JP 2007-138533 A

  By the way, the work of attaching the closed cable to the actuator is time-consuming and complicated. Therefore, there is room for improvement in the mounting structure of the closed cable. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle door closer in which a closed cable can be easily attached.

(1) A vehicular door closer that solves the above-mentioned problem is a motor that moves the movable body via a power conversion mechanism, a closed cable connected to a latch device that fixes the vehicle door, a movable body that pulls the closed cable. A cable connecting portion to which the close cable is connected is provided at an axial end of the moving body having an axial shape, and the cable connecting portion extends along an axial direction of the moving body. The cable connection portion is provided with an engagement recess in which an engagement end of an inner cable of the closed cable is engaged, and provided so as to pass from the axial end surface of the cable connection portion to the engagement recess. and the insertion groove is provided that the inner cable of the closing cable is inserted, the axial end surface of the cable connecting portion, the axis from the axial center portion of said cable connecting portion As going to the orthogonal direction outwardly inclined so as to approach the opening of the engaging recess.

In this configuration, since the axial end surface of the cable connection portion is inclined as described above, when the inner cable is moved so that the engagement end portion of the inner cable is directed to the end surface of the moving body, the engagement end portion is moved to the end surface. Along with the engagement end into the engagement recess. Thus, according to the above configuration, the inner cable and the moving body can be easily connected.

(2) In the door closer for the vehicle, the axial end surface of the cable connecting portion inclined so as to approach the opening of the engaging recess as going to the orthogonal direction outer side of the axis from the axial center portion of said cable connecting portion And an extension area that is an extension of the inclination area and extends on the opposite side to the inclination area with respect to the axial center.

  When connecting the inner cable to the moving body, when the engaging end of the inner cable is moved toward the end surface of the moving body, the engaging end of the inner cable is opposite to the inclined area from the center of the moving body. There is a case where it is shifted to the side. Also in this case, according to the above configuration, the engagement end comes into contact with the extension region, and the engagement end moves to the inclined region. Therefore, the engagement end portion is less likely to deviate from the path of moving from the end surface of the moving body toward the engagement concave portion as compared with a case where such an extension region does not exist. This reduces the occurrence of a situation where the engagement end does not enter the engagement recess.

  (3) The vehicle door closer further includes: a case that accommodates the moving body, the case having an opening through which the close cable is inserted, and a cap that covers the opening of the case. Attached to a closed cable.

  According to this configuration, the operation of inserting the closed cable through the opening of the case and the operation of covering the opening of the case with the cap can be performed in a series of operations. This simplifies the assembly operation.

  (4) The vehicle door closer further includes a cancel mechanism that cuts off power transmission from the motor to the latch device based on an operation of a cancel cable. According to this configuration, the operation of the latch device based on the driving of the motor is released by operating the cancel cable.

  (5) In the vehicle door closer, the moving body has a screw portion, and the power conversion mechanism includes a wheel to which the moving body is screwed, the wheel being rotated by the rotational power of the motor; It has an insertion hole to be inserted, guides the moving body so as to move in the axial direction, and rotates integrally with the moving body by engaging the moving body with the moving body so that it cannot rotate relative to the moving body in the circumferential direction. And a guide for obtaining, wherein the cancel mechanism restricts the rotation of the guide when the cancel cable is not operated, and releases the restriction on the rotation of the guide based on the operation of the cancel cable.

  According to this configuration, the rotation of the guide is controlled based on the operation of the cancel cable. When the rotation of the guide is restricted, the moving body moves in the axial direction. On the other hand, when the restriction on the rotation of the guide is released, power transmission from the motor to the latch device via the guide and the moving body is cut off. That is, the power transmission via the guide and the moving body is controlled by operating the cancel cable.

  (6) In the vehicle door closer, the case has a boss that supports the outer of the cancel cable and the inner cable of the cancel cable is inserted, and the case cancels the inner cable of the cancel cable. It has a guide portion for guiding to a cable receiving portion of the mechanism.

  According to this configuration, when the inner cable of the cancel cable is engaged with the cable receiving portion, when the inner cable is inserted into the boss of the case, the inclination of the inner cable is limited by the boss of the case and the guide portion of the case. You. In this way, the occurrence of a situation in which the end of the inner cable does not engage with the cable receiving portion is reduced.

  The above vehicle door closer is easy to attach the close cable.

The vehicle door closer will be described with reference to FIGS.
FIG. 1 is a front view showing the vehicle door 1, and FIG. 2 is a plan view of the vehicle door 1. As shown in FIG. 1, a vehicle door 1 is attached to a vehicle body 2 (vehicle body) so as to be openable and closable, and opens and closes a doorway. A vehicle door closer 10 is mounted in the vehicle door 1. The vehicle door closer 10 includes a latch device 20, an actuator 40 that drives the latch device 20, and a close cable 31 that connects the latch device 20 and the actuator 40. Preferably, a cancel cable 35 is connected to the actuator 40.

  The latch device 20 is mounted on an end of the vehicle door 1. The latch device 20 is engaged with the striker 3 fixed to the vehicle body 2 and maintains the vehicle door 1 in a half-door state or a fully-closed state. The latch device 20 operates based on the operation of the inside door handle 4 and the outside door handle 5 (hereinafter, referred to as “door handles 4 and 5”). When the operating power from any of the door handles 4 and 5 is transmitted to the latch device 20, the latch device 20 releases the engagement with the striker 3 and opens the vehicle door 1.

The latch device 20 operates by transmitting the power of the motor 41 of the actuator 40, and shifts the vehicle door 1 from the half-door state to the fully closed state.
The actuator 40 cuts off the transmission of power from the motor 41 to the latch device 20 based on the operation of one of the door handles 4 and 5 while the motor 41 is being driven. Thus, in the latch device 20, the interference between the operation by one of the door handles 4 and 5 and the operation by the power of the actuator 40 is suppressed.

An example of the latch device 20 will be described with reference to FIGS. In FIG. 3, a part of the case 21 is omitted.
The latch device 20 includes a case 21 for accommodating various components, a latch 22 rotatably mounted on the case 21, a pole 23 rotatably mounted on the case 21 and restricting rotation of the latch 22, and a latch 22. A lever for rotation (hereinafter, referred to as “latch lever 24”) and a link mechanism 25 to which the door handles 4 and 5 are connected are provided.

  The latch 22 has a concave portion 22a into which the striker 3 is inserted, a first claw portion 22b and a second claw portion 22d arranged so as to sandwich the concave portion 22a, and a pressing portion 22f pressed by the latch lever 24. The first claw portion 22b is arranged on the vehicle inner side in the vehicle width direction than the second claw portion 22d. A first engaging portion 22c that engages with the pawl 23 is provided on the tip of the first claw portion 22b on the side opposite to the concave portion 22a. A second engaging portion 22e that engages with the pawl 23 is provided at the tip of the second claw portion 22d on the concave portion 22a side.

  The latch 22 is located between a first position where the opening 22x of the concave portion 22a faces the approach path of the striker 3 and a second position where the first claw portion 22b is arranged to cross the approach path. Rotate with. The latch 22 is biased to rotate from the second position toward the first position (see the arrow A in FIG. 3A). In the first position, the latch 22 contacts the stopper 26. At an intermediate position between the first position and the second position, the latch 22 is locked by the engagement between the pawl 23 and the second engaging portion 22e of the second claw portion 22d. In the second position, the latch 22 is locked by the engagement between the first engaging portion 22c of the first claw portion 22b and the pawl 23. The state in which the latch 22 is disposed at the first position is referred to as an "open latch state", and the state in which the latch 22 is disposed at an intermediate position is referred to as a "half latch state". It is called "half-door state." The state where the latch 22 is located at the second position is referred to as a “full latch state”.

  The latch 22 operates as follows. When the vehicle door 1 is open, the latch 22 is located at the first position, as shown in FIG. When the vehicle door 1 is closed and the latch 22 moves toward the striker 3, the striker 3 moves relatively to the latch 22, and the striker 3 enters the recess 22 a of the latch 22. Then, the latch 22 rotates and shifts to the second position via the intermediate position as shown in FIG. 3B (see the position of the latch 22 in FIG. 3C).

The latch lever 24 in the latch device 20 will be described.
The latch lever 24 has a contact portion 24a that contacts the pressing portion 22f of the latch 22. The latch lever 24 is located between an initial position where the latch 22 does not interfere with the latch 22 (see FIG. 3A) and an end position where the latch 22 can be rotated to the second position (see the latch lever 24 in FIG. 3C). Rotate with. The latch lever 24 is biased to rotate from the end position toward the initial position (see the arrow B in FIG. 3A). The latch lever 24 is connected to the latch-side end 32 a of the inner cable 32 of the close cable 31. When the inner cable 32 is pulled, the latch lever 24 rotates from the initial position toward the terminal position.

  When the latch lever 24 starts rotating toward the end position when the latch 22 is located at the intermediate position, the contact portion 24a of the latch lever 24 contacts the pressing portion 22f of the latch 22. When the latch lever 24 rotates to the end position, the latch 22 is pushed by the latch lever 24 and rotates to the second position.

Next, the link mechanism 25 will be described.
The link mechanism 25 transmits the operating power of the door handles 4 and 5 to the latch device 20 and the actuator 40.

  When one of the door handles 4, 5 is operated, the operating power is transmitted to the pawl 23 of the latch device 20 via the link mechanism 25. When power based on the operating power of the door handles 4 and 5 is applied to the pawl 23, the pawl 23 rotates from a position where it engages with the latch 22 to a position where it does not engage with the latch 22. At this time, the latch 22 returns from the intermediate position to the first position or from the second position to the first position. That is, the operation of the door handles 4 and 5 enables the opening and closing of the vehicle door 1.

  Further, the link mechanism 25 operates the cancel mechanism 43 (see below) of the actuator 40 as follows based on the operation of the door handles 4 and 5. That is, when one of the door handles 4 and 5 is operated, the operation power is transmitted to the cancel lever 61 (see below) of the actuator 40 via the link mechanism 25. When the operating power of the door handles 4 and 5 is applied to the cancel lever 61, the cancel lever 61 shuts off the transmission of power from the actuator 40 to the latch device 20 (that is, shutting off means that power is not transmitted).

The actuator 40 will be described with reference to FIGS.
The actuator 40 includes a motor 41, a spindle 53 as a moving body, a power conversion mechanism 42 that moves the spindle 53 in the axial direction (along the center axis C of the spindle 53) by the rotational power of the motor 41, and a motor 41. A cancel mechanism 43 for canceling the movement of the spindle 53 based on the driving. Further, the actuator 40 includes a case 44 and two caps (hereinafter, referred to as a “first cap 45” and a “second cap 46”, respectively).

  FIG. 4 is an exploded perspective view of the actuator 40. FIG. 4 shows the case 44, the spindle 53, the first cap 45, and the second cap 46, and other components are omitted. FIG. 5A is a plan view of the actuator 40, and FIG. 5B is a view in which the case half 44p is removed.

  As shown in FIGS. 4 to 6, the case 44 includes a pair of case halves 44p and 44q. One of the pair of case halves 44p and 44q covers one side of the housing space, and the other covers the other side of the housing space. The spindle 53, the motor 41, the power conversion mechanism 42, and the cancellation mechanism 43 are housed in a housing space formed by the pair of case halves 44p and 44q.

  Two bosses (hereinafter, referred to as “first boss 44a” and “second boss 44b”) are provided on the side surface of the case 44. A first opening 44c is provided on an end face of the first boss 44a. A second opening 44d is provided at an end surface of the second boss 44b. The first boss 44a is covered with a first cap 45 that covers the first opening 44c. The second boss 44b is covered with a second cap 46 that covers the second opening 44d.

  As shown in FIGS. 5B and 6B, the power conversion mechanism 42 includes a worm gear 51 fixed to the output shaft of the motor 41, and a worm wheel 52 ("wheel") meshing with the worm gear 51 on the outer surface. ), And a guide 54 through which the spindle 53 is inserted.

The worm wheel 52 is formed in a ring shape. On the inner peripheral surface of the worm wheel 52, a screw that meshes with the screw portion 53a of the spindle 53 is provided.
The spindle 53 is screwed into the worm wheel 52 and moves in the front-rear direction by rotating relative to the worm wheel 52. “Front” in the front-rear direction indicates the end of the spindle 53 to which the closed cable 31 is connected, and “rear” indicates the opposite side of the front. The spindle 53 is urged forward by a coil spring 56.

  At the front end of the spindle 53, a cable connection part 70 to which the close cable 31 is connected is provided. Two convex portions 53b projecting from the peripheral surface are provided on the front peripheral surface of the spindle 53 (portion where no screw is provided) (see FIG. 6B). The two convex portions 53b are arranged at positions opposite to each other with respect to the center axis C of the spindle 53.

  The spindle 53 has a position where the closed cable 31 is most pulled out from the case 44 (hereinafter, referred to as a “minimum pulling position”), and a position where the closed cable 31 is pulled most into the case 44 (hereinafter, referred to as a “maximally pulled position”). Move between.

  As shown in FIG. 6B, the guide 54 has an insertion hole 54a through which the spindle 53 is inserted. On the inner surface of the insertion hole 54a, a guide groove 54b into which the projection 53b of the spindle 53 enters is provided. The guide groove 54b extends along the axial direction of the spindle 53. The protrusion 53b of the spindle 53 enters the guide groove 54b, whereby the rotation of the spindle 53 with respect to the guide 54 is restricted. That is, the guide 54 is engaged with the spindle 53 so as not to rotate relatively in the circumferential direction, and the guide 54 supports the spindle 53 so as to be relatively movable in the axial direction. A regulating section 55 for regulating the rotation of the guide 54 is provided on the outer surface of the guide 54. The restricting portion 55 has a restricting surface 55a with which the engaging body 60 of the cancel mechanism 43 contacts. The outer shape of the cross section of the guide 54 in the restricting portion 55 is formed, for example, as shown in FIG. 8, in a shape obtained by bending each side of the regular octagon toward the center. In this example, the curved surface is a surface corresponding to the regulating surface 55a.

  As shown in FIGS. 7A and 7B, the cancel mechanism 43 includes an engaging body 60 that engages with the restricting portion 55 of the guide 54 and a cancel lever 61 that moves the engaging body 60. As shown in FIG. 8, the engagement body 60 has a main body 60a and a protruding part 60b protruding from the main body 60a. The main body 60a has an engagement surface 60c curved along the regulating surface 55a of the guide 54. The engaging body 60 has a contact position (see a solid line in FIG. 8) where the engaging surface 60c contacts the regulating surface 55a of the guide 54, and a separating position (see FIG. 8) in which the engaging surface 60c separates from the regulating surface 55a of the guide 54. (See the two-dot chain line).

  The cancel lever 61 has a lever main body 62, an insertion hole 63 through which the protrusion 60 b of the engagement body 60 is inserted, and a cable receiving portion 64 that engages with the engagement end 36 b of the inner cable 36 of the cancel cable 35. .

  The cancel lever 61 rotates between a first position and a second position. The first position indicates a position where the cancel lever 61 restricts the rotation of the guide 54. Hereinafter, this position is referred to as a “regulation position”. The second position indicates a position where the cancel lever 61 releases the rotation restriction of the guide 54. Hereinafter, this position is referred to as a “release position”. The cancel lever 61 is urged to move from the release position to the restriction position. When the inner cable 36 is pressed by the cancel cable 35, the cancel lever 61 rotates from the restriction position to the release position.

  The insertion hole 63 includes a first portion 63a separated from the rotation center of the cancel lever 61 by a first distance, a second portion 63b separated from the rotation center of the cancel lever 61 by a second distance shorter than the first distance, and a second portion 63b. It is composed of a connecting portion 63c connecting the first portion 63a and the second portion 63b. With the rotation of the cancel lever 61, the engagement body 60 moves as follows. When the cancel lever 61 is located at the regulation position, the protruding portion 60b of the engagement body 60 is disposed on the first portion 63a of the insertion hole 63, and the engagement body 60 is positioned at the contact position. At this time, the engagement body 60 comes into contact with the regulating portion 55 of the guide 54. When the cancel lever 61 is located at the release position, the protrusion 60b of the engagement body 60 is located at the second portion 63b of the insertion hole 63, so that the engagement body 60 is positioned at the separated position. At this time, the engagement body 60 separates from the regulating portion 55 of the guide 54. That is, the rotation of the guide 54 is restricted by the arrangement of the cancel lever 61 at the restricted position. The rotation restriction of the guide 54 is released by disposing the cancel lever 61 at the release position.

The power conversion mechanism 42 operates as follows.
When the rotation of the guide 54 is restricted, the rotation of the spindle 53 is also restricted by the engagement between the projection 53b of the spindle 53 and the guide groove 54b. Therefore, when the rotation of the guide 54 is restricted and the worm wheel 52 rotates in a predetermined direction via the worm gear 51 by the drive of the motor 41, the spindle 53 moves rearward.

  When the rotation restriction of the guide 54 is released, the spindle 53 and the guide 54 can rotate integrally by the engagement between the projection 53b of the spindle 53 and the guide groove 54b. Therefore, when the rotation of the guide 54 is released and the worm wheel 52 rotates in a predetermined direction via the worm gear 51 by driving the motor 41, the spindle 53 and the guide 54 rotate integrally. Since the spindle 53 is urged forward by the coil spring 56, the spindle 53 and the guide 54 move forward while rotating integrally.

The operation of the vehicle door closer 10 in the half-door state will be described.
The motor 41 is controlled to be driven when the latch 22 is in the half-latch state (that is, when the latch 22 is in the half-door state and the latch 22 is located at the intermediate position).

  When the latch 22 enters the half-latched state, the motor 41 is driven. When the door handles 4 and 5 are not operated, the cancel lever 61 is located at the regulation position and the rotation of the guide 54 and the spindle 53 is regulated. Move backward. Thereby, the inner cable 32 of the closed cable 31 is pulled. Then, the latch lever 24 rotates due to the pulling of the inner cable 32 of the close cable 31, and the latch 22 rotates to the second position in conjunction with this. As a result, the latch 22 enters the full latch state, and the vehicle door 1 enters the fully closed state.

  When one of the door handles 4 and 5 is operated while the motor 41 is being driven, the inner cable 36 of the cancel cable 35 operates via the link mechanism 25, and the cancel lever 61 is operated based on the operation of the inner cable 36. Rotate. When the cancel lever 61 rotates from the regulation position to the release position, the engagement body 60 moves to the separated position, and the engagement between the engagement body 60 and the guide 54 is released. Then, by driving the motor 41, the spindle 53 and the guide 54 rotate integrally, and the spindle 53 moves forward by the urging force of the coil spring 56. Since the latch lever 24 of the latch device 20 returns to the initial position, the engagement between the latch lever 24 and the latch 22 is released.

  Thus, when the latch 22 is in the half-latch state and the latch 22 is shifting to the full-latch state by driving the motor 41, and when the door handles 4 and 5 are operated, the motor 41 is operated based on the operation. The transmission of power from the motor to the latch 22 is interrupted. Therefore, the latch 22 can be smoothly shifted to the open latch state based on the operation of the door handles 4 and 5.

Next, a connection structure between the closed cable 31 and the spindle 53 will be described.
As shown in FIG. 6B, the engagement end 32 b of the inner cable 32 of the close cable 31 engages with the cable connection 70 of the spindle 53. The engagement end 32b of the inner cable 32 is configured as a portion wider than the line width (that is, the diameter) of the inner cable 32, and the distal end of the engagement end 32b is configured as a convex curved surface. For example, the engagement end 32b may be configured as a sphere, a bullet, or an ellipsoid.

  A first cap 45 is attached to an end of the closed cable 31 (see FIG. 4). As shown in FIG. 6B, the first cap 45 covers the first opening 44c of the case 44. The first cap 45 is a portion that protrudes from the center of the cap body 45a and covers the periphery of the first opening 44c of the case 44 (that is, the side surface of the first boss 44a). Boss 45b. The cap body 45a has a lid 45p and a peripheral wall 45q provided along the periphery of the lid 45p. The boss 45b projects from the lid 45p of the cap body 45a toward the side opposite to the peripheral wall 45q. The boss hole 45c of the boss 45b is provided with a step 45d in which the outer 33 of the closed cable 31 is arranged.

  With reference to FIGS. 9A to 9D, the structure of the cable connection unit 70 will be described. 9A is a front view of the cable connecting portion 70, FIG. 9B is a side view thereof, FIG. 9C is a rear view thereof, and FIG. 9D is along the line DD. It is sectional drawing.

  The cable connecting portion 70 is provided with a concave portion (hereinafter, referred to as an “engaging concave portion 72”) behind the end surface 71 of the cable connecting portion 70 (that is, the end surface 71 of the spindle 53). The engagement recess 72 accommodates the engagement end 32 b of the inner cable 32 of the closed cable 31. The front surface 72c in the engagement concave portion 72 is inclined perpendicular to the center axis C of the spindle 53 or forward toward the bottom surface 72a of the engagement concave portion 72 in order to prevent the engagement end portion 32b of the inner cable 32 from coming off. (See FIG. 9D).

  The end face 71 of the cable connection part 70 is inclined. Specifically, end face 71 includes inclined region 71a. The inclined region 71a is inclined so as to approach the opening 72b of the engagement recess 72 as going outward from the center of the spindle 53. Preferably, end face 71 includes an extension area 71b extending on the opposite side of inclined area 71a with respect to the center of spindle 53. The inclined region 71a and the extended region 71b are continuous and form a flat or curved surface.

  The cable connecting portion 70 is provided with a groove (hereinafter, referred to as “insertion groove 73”) through which the inner cable 32 of the close cable 31 is inserted. The insertion groove 73 is provided on the side surface of the spindle 53 where the engagement recess 72 opens, and is provided from the end face 71 to the engagement recess 72. The insertion groove 73 extends along the center axis C of the spindle 53. The insertion groove 73 is configured such that the center axis C of the spindle 53 passes through the insertion groove 73. The end face 71 of the spindle 53 is divided into two with the insertion groove 73 interposed therebetween. A tapered surface 73b is provided between the inner surface 73a of the insertion groove 73 and the end surface 71.

With reference to FIGS. 10A to 10D, a method of connecting the inner cable 32 of the closed cable 31 and the cable connection unit 70 will be described.
As shown in FIG. 10A, before connecting the inner cable 32 to the cable connection part 70, the inner cable 32 is previously arranged at a predetermined position with respect to the first cap 45. Specifically, the latch side end 32 a of the inner cable 32 is attached to the latch lever 24 of the latch device 20. Then, since the inner cable 32 is pulled by the latch lever 24, the engagement end portion 32b of the inner cable 32 is arranged at a predetermined position. Then, the spindle 53 is arranged at the minimum traction position.

  Next, as shown in FIG. 10B, the tip of the first cap 45 is inserted into the first boss 44a of the case 44. Then, the engagement end 32 b of the inner cable 32 is arranged so as to face the end surface 71 of the spindle 53.

  Next, as shown in FIG. 10C, when the first cap 45 is inserted up to the intermediate portion of the first boss 44a of the case 44, the engaging end 32b is moved along the end surface 71 of the spindle 53 into the engaging recess. 72, and comes into contact with the side surface of the spindle 53 (the portion between the end surface 71 and the engagement concave portion 72). At this time, the inner cable 32 is curved, and the elasticity thereof causes the engaging end 32b to press the side surface.

  Further, as shown in FIG. 10D, when the first cap 45 is inserted into the first boss 44a of the case 44 until the first cap 45 is attached to the first boss 44a of the case 44, the first cap 45 is bent by elasticity. The inner cable 32 enters the insertion groove 73 while returning to the original position, and accordingly, the engagement end 32b enters the engagement recess 72. As shown above, when the first cap 45 is inserted into the first boss 44 a of the case 44, the inner cable 32 is connected to the spindle 53.

  Next, a connection structure between the cancel cable 35 and the cancel lever 61 will be described with reference to FIGS. As shown in FIG. 5B, the engagement end 36 b of the inner cable 36 of the cancel cable 35 engages with the cable receiving portion 64 of the cancel lever 61. The engagement end 36b of the inner cable 36 is configured as a portion wider than the line width (that is, the diameter) of the inner cable 36, and the distal end surface of the engagement end 36b is configured as a convex curved surface. For example, the engagement end 36b may be configured as a sphere or an ellipsoid.

  A second cap 46 is attached to an end of the cancel cable 35 (see FIG. 4). As shown in FIG. 6A, the second cap 46 covers the second opening 44d of the case 44. The second cap 46 has a cap body 46a that covers the periphery of the second opening 44d of the case 44 (that is, the side surface of the second boss 44b), and a boss 46b through which the cancel cable 35 is inserted. The cap body 46a has an end 46p and a peripheral wall 46q provided along the periphery of the end 46p. The boss 46b extends in the same direction as the direction in which the peripheral wall 46q projects at the end 46p. The boss 46b is inserted through the second boss 44b of the case 44. The boss hole 46c of the boss 46b is provided with a step 46d in which the outer 37 of the cancel cable 35 is arranged.

  As shown in FIG. 11A, the case 44 is provided with a guide portion 44e for guiding the inner cable 36 of the cancel cable 35. The guide portion 44e is provided so as to protrude from a case half 44p different from the case half 44q that supports the cancel lever 61. The guide portion 44e includes, for example, two guide pins 44f, and the two guide pins 44f are arranged so as to sandwich the inner cable 36. Further, the two guide pins 44f are arranged at a position where the distance from the case-side opening 44g of the second boss 44b is equal to the distance from the cable receiving portion 64 or around the same. The two guide pins 44f are arranged at intervals in a direction intersecting the insertion direction of the inner cable 36, and the distance between the two guide pins 44f is determined by the insertion end 36b of the inner cable 36. It is set to a size that can be used. The two guide pins 44f are arranged such that the engagement ends 36b come into contact with each other when the engagement ends 36b of the inner cable 36 are located outside the predetermined range. The predetermined range refers to a region formed by the entire path or a part of the path of the engagement end 36b capable of engaging the engagement end 36b of the inner cable 36 with the cable receiving portion 64. .

  The cable receiving portion 64 of the cancel lever 61 has the following structure. The cable receiving portion 64 of the cancel lever 61 accommodates a part (preferably half) of the engaging end 36b of the cancel cable 35. The inner surface of the cable receiving portion 64 is formed into a concave curved surface such that when the engaging end portion 36b rolls while being housed in the cable receiving portion 64, the engaging end portion 36b comes into contact with the rolling range. . For example, when the engagement end portion 36b is a sphere, the cable receiving portion 64 is formed as a concave curved surface having a predetermined radius.

  With reference to FIGS. 11A and 11B, an engagement method for engaging the inner cable 36 of the cancel cable 35 with the cable receiving portion 64 of the cancel lever 61 will be described.

  First, before the inner cable 36 is engaged with the cancel lever 61, the inner cable 36 is previously arranged at a predetermined position with respect to the second cap 46. Specifically, the other end 36a of the inner cable 36 (that is, the end opposite to the engagement end 36b) is attached to the latch device 20. Then, the engagement end 36b of the inner cable 36 is arranged at a predetermined position.

  Next, the boss 46b of the second cap 46 is inserted into the second boss 44b of the case 44. As shown in FIG. 11A, when the boss 46b of the second cap 46 is inserted up to half of the boss 46b, the engaging end 36b is inserted between the pair of guide pins 44f or comes into contact with the guide pins 44f. . When the engagement end 36b contacts the guide pin 44f, the outside of the engagement end 36b contacts the guide pin 44f. In this manner, the inner cable 36 is suppressed from being disposed outside between the two guide pins 44f. When the second cap 46 is inserted into the second boss 44b of the case 44 until the second cap 46 is attached to the second boss 44b of the case 44, as shown in FIG. The portion 36b is received in the cable receiving portion 64 of the cancel lever 61. As described above, by inserting the second cap 46 into the second boss 44b of the case 44, the inner cable 36 and the cancel lever 61 are engaged.

Next, the operation of the actuator 40 will be described.
As described above, the actuator 40 is configured such that the portion to which the close cable 31 is connected (that is, the cable connection portion 70) and the portion to which the cancel cable 35 is engaged (that is, the cable receiving portion 64 of the cancel lever 61) are inside the case 44. Are located in For this reason, waterproofness is higher than a structure in which these portions are exposed.

  By the way, when the cable connecting part 70 and the cable receiving part 64 are arranged in the case 44, the cable connecting part 70 and the cable receiving part 64 are arranged outside the case 44 depending on the structure of the cable connecting part 70 and the cable receiving part 64. There is a possibility that the transportability of the actuator 40 may be reduced as compared with the case where it is performed.

  For example, it is assumed that the cable connecting portion 70 has a structure in which the engaging end 32b of the inner cable 32 is inserted into the cable connecting hole while visually checking. In this case, the connection between the inner cable 32 and the cable connection part 70 is performed as follows. The spindle 53, the motor 41, the power conversion mechanism 42, the cancel mechanism 43, and the like are arranged in the case half 44q, and the cable connection hole is placed in a state where the cable connection hole can be viewed without attaching the other case half 44p. Then, the inner cable 32 and the cable connection part 70 are connected in the opened state. The same applies to the connection of the cancel cable 35. Thereafter, the other case half 44p is put on the case half 44q on which the motor 41 and the like are mounted. In the module assembled in this manner, the latch device 20 and the actuator 40 are connected by the close cable 31 and the cancel cable 35. However, such a module in which two devices are connected by a cable has a problem that the cable may be caught by an obstacle during the transportation in the assembly factory, and the transportability is poor. From the viewpoint of transportability, it is desirable that the actuator 40 has a case 44 in which the spindle 53, the motor 41, the power conversion mechanism 42, the cancel mechanism 43, and the like are not connected.

  Therefore, the actuator 40 according to the embodiment can connect the close cable 31 and the cancel cable 35 to the actuator 40 even after the spindle 53, the motor 41, the power conversion mechanism 42, the cancel mechanism 43, and the like are housed in the case 44. Has a possible structure. That is, as shown in FIGS. 10A to 10D, after the above-described actuator 40 accommodates the spindle 53, the motor 41, the power conversion mechanism 42, the cancellation mechanism 43, and the like in the case 44, The closed cable 31 can be connected to the cable connection unit 70. Further, as shown in FIGS. 11A and 11B, the cancel cable 35 can be engaged with the cable receiving portion 64. Therefore, the actuator 40 can be transported without being connected to the latch device 20. Thus, there is an advantage that the actuator 40 according to the embodiment is easy to carry.

  Further, the actuator 40 according to the embodiment also has an advantage that the area that can be arranged is large as described below. In the structure of the conventional actuator 40, a planetary gear mechanism is used instead of the spindle 53, and the planetary gear mechanism and the cable connection lever are arranged along the rotation center axis of the carrier of the planetary gear mechanism. . On the other hand, the cable connection section 70 is provided at the tip of the spindle 53. The diameter of the guide 54 through which the spindle 53 is inserted can be configured to be approximately the thickness (length in the rotation axis direction) of the planetary gear mechanism. Therefore, the thickness of the actuator 40 according to the embodiment is larger than the thickness of the conventional actuator 40 (the thickness of the planetary gear mechanism + the thickness of the cable connection lever) by the thickness of the cable connection lever. It can be made small. Since the internal space of the vehicle door 1 is narrow, the area that can be arranged in the vehicle door 1 increases as the thickness of the device mounted in the vehicle door 1 decreases. In this regard, since the actuator 40 according to the embodiment can be configured to be thinner than the conventional actuator 40, the mountable area in the vehicle door 1 is increased.

Hereinafter, effects of the vehicle door closer 10 according to the present embodiment will be described.
(1) In the present embodiment, the spindle 53 is provided with the engagement recess 72 and the insertion groove 73. The engagement end 32b of the inner cable 32 of the close cable 31 engages with the engagement recess 72. The insertion groove 73 is provided so as to extend from the end surface 71 of the spindle 53 (that is, the end surface 71 of the cable connection portion 70) to the engagement concave portion 72. The inner cable 32 of the close cable 31 is inserted into the insertion groove 73. Further, the end face 71 of the spindle 53 is inclined so as to approach the opening 72b of the engagement recess 72 as going outward from the center.

  In this configuration, since the end surface 71 of the spindle 53 is inclined as described above, when the inner cable 32 is moved so that the engagement end 32b of the inner cable 32 faces the end surface 71 of the spindle 53, the engagement end 32b Moves along the end face 71 of the spindle 53, and the engagement end 32 b enters the engagement recess 72. As described above, according to the above configuration, the inner cable 32 and the spindle 53 can be easily connected.

  (2) In the present embodiment, the end surface 71 of the spindle 53 is formed by an inclined region 71a inclined so as to approach the opening 72b of the engagement concave portion 72 from the center to the outside, and an extension of the inclined region 71a and the center. And an extension region 71b extending on the opposite side to the inclined region 71a with respect to the portion.

  When connecting the inner cable 32 and the spindle 53, when the engagement end 32 b of the inner cable 32 is moved toward the end surface 71 of the spindle 53, the engagement end 32 b of the inner cable 32 May be arranged on the opposite side to the inclined region 71a. Even in this case, according to the above configuration, the engagement end 32b comes into contact with the extension region 71b, and the engagement end 32b moves to the inclined region 71a. Therefore, the engagement end portion 32b is less likely to deviate from the path of moving from the end surface 71 of the spindle 53 toward the engagement concave portion 72 as compared with the case where the extension region 71b does not exist. Thereby, the occurrence of a situation where the engagement end portion 32b does not enter the engagement concave portion 72 is reduced.

  (3) In the present embodiment, the vehicle door closer 10 includes the case 44 and the first cap 45. The first cap 45 covers the first opening 44c of the case 44. The first cap 45 is attached to the closed cable 31. According to this configuration, the operation of inserting the closed cable 31 into the first opening 44c of the case 44 and the operation of covering the first opening 44c of the case 44 with the first cap 45 can be performed in a series of operations. This simplifies the assembly operation.

  (4) In the present embodiment, the vehicle door closer 10 includes the cancel mechanism 43. The cancel mechanism 43 cuts off power transmission from the motor 41 to the latch device 20 based on the operation of the cancel cable 35. According to this configuration, the operation of the latch device 20 based on the driving of the motor 41 is released by operating the cancel cable 35.

  (5) In the present embodiment, the power conversion mechanism 42 of the actuator 40 includes the worm wheel 52 and the guide 54. The worm wheel 52 has a spindle 53 screwed therein and is rotated by the rotating power of the motor 41. The guide 54 has an insertion hole 54a through which the spindle 53 is inserted, guides the spindle 53 to move in the axial direction, and engages with the spindle 53 so that it cannot rotate relative to the spindle 53 in the circumferential direction. It can rotate integrally with the spindle 53. The cancel mechanism 43 regulates the rotation of the guide 54 when the cancel cable 35 is not operated, and releases the regulation of the guide 54 based on the operation of the cancel cable 35.

  According to this configuration, the rotation of the guide 54 is controlled based on the operation of the cancel cable 35. The rotation of the guide 54 causes the spindle 53 to move in the axial direction. When the spindle 53 moves, the latch device 20 operates. On the other hand, when the rotation restriction of the guide 54 is released, power transmission from the motor 41 to the latch device 20 via the guide 54 and the spindle 53 is cut off. That is, the operation of the cancel cable 35 controls the transmission of power from the motor 41 to the latch device 20 via the guide 54 and the spindle 53.

  (6) In the present embodiment, the case 44 has the second boss 44b. The second boss 44b supports the outer 37 of the cancel cable 35. The inner cable 36 of the cancel cable 35 is inserted through the second boss 44b. On the other hand, the case 44 has a guide portion 44e. The guide section 44 e guides the inner cable 36 of the cancel cable 35 to the cable receiving section 64 of the cancel mechanism 43.

  According to this configuration, when the inner cable 36 of the cancel cable 35 is inserted into the second boss 44 b of the case 44 when the inner cable 36 of the cancel cable 35 is engaged with the cable receiving portion 64, the inclination of the inner cable 36 It is limited by the second boss 44b and the guide portion 44e of the case 44 (see FIGS. 11A and 11B). In this way, the occurrence of a situation in which the engagement end portion 36b of the inner cable 36 does not engage with the cable receiving portion 64 is reduced.

<Other embodiments>
In the present embodiment, in the actuator 40, the moving body that pulls the closed cable 31 is configured as the spindle 53, but the structure of the moving body is not limited to this. For example, the moving body can be configured as a lever that rotates around a spindle. In this case, the lever is rotated by the rotational power of the motor 41. At the end of the lever, a connection portion similar to the cable connection portion 70 is provided. Thereby, the effect (1) is obtained.

  In the present embodiment, the spindle 53 is provided with the cable connection portion 70, and the end surface 71 of the cable connection portion 70 is configured to include the inclined region 71a and the extension region 71b. On the other hand, the end surface 71 may be configured to include the plurality of inclined regions 71a without including the extension region 71b. For example, the two inclined regions 71a are arranged so that the pair of inclined regions 71a are mirror-symmetric with respect to the central axis of the cable connection part 70 (the central axis C of the spindle 53). And the engagement recessed part 72 is provided so that it may correspond to each of a pair of inclination area 71a. According to this structure, when the engagement end portion 32b of the inner cable 32 of the close cable 31 abuts on one of the pair of inclined regions 71a, it enters the engagement concave portion 72 corresponding to the abutted inclined region 71a.
