JP7730792B2 - Cable mounting structure and window regulator - Google Patents

Description

The present invention relates to a cable mounting structure and a window regulator.

Window regulators are used as devices for raising and lowering vehicle window glass (see, for example, Patent Document 1).

The window regulator shown in Patent Document 1 comprises a carrier plate that holds the window glass, a cable connected at one end to the carrier plate, a drum connected at the other end of the cable, and a drive motor that rotates the drum. The drive motor rotates the drum, winding or unwinding the cable, which raises or lowers the carrier plate and thereby raises or lowers the window glass.

The cable is connected to the carrier plate by housing the cable end and spring in the housing of the carrier plate. The spring is arranged around the end, with one end seating surface contacting the bottom of the end housing and the other end seating surface contacting the flange portion of the end.

Japanese Patent Application Laid-Open No. 2020-90888

However, because the outer diameter of the spring is smaller than the outer diameter of the flange at the end, a gap forms between the inner wall of the end housing and the outer surface of the spring. This gap can cause axial misalignment between the spring and the end, causing the spring to hit the inner wall of the housing and generating abnormal noise.

The purpose of this disclosure is to provide a cable mounting structure and window regulator that can reduce the generation of abnormal noise by suppressing axial misalignment of the spring.

The cable mounting structure disclosed herein is a mounting structure for mounting a cable to a carrier plate, wherein the cable has a cable body and a terminal member. The terminal member is disposed at the end of the cable body. The terminal member has a terminal member body and a spring seat. The terminal member body has a spring disposed around it. The seat is disposed on the side of the spring opposite to the side to which the cable is connected. The carrier plate has a housing portion. The housing portion houses the terminal member and the spring. The housing portion has a first housing portion and a second housing portion. The seat portion is slidable in the first housing portion. The second housing portion is disposed on the side of the first housing portion from which the cable extends, restricts movement of the spring in a direction perpendicular to the axis of the terminal member body, and has a smaller cross-sectional area perpendicular to the axis than the first housing portion. The second housing portion has an end face and an inner surface. The end face has a first penetration portion formed therein through which the cable is inserted, and restricts movement of the terminal member beyond a predetermined level toward the side to which the cable is connected. The inner surface is formed along the axis from the outer edge of the end surface and is arranged around the spring. The inner surface has a sloped portion on the end surface side of the inner surface, which is the part of the inner surface that approaches the terminal member when tension is generated in the cable, that slopes closer to the axis as it approaches the end surface.

The window regulator of the present disclosure comprises a carrier plate, a cable, a cable guide, and a drum. The carrier plate holds the window glass. One end of the cable is connected to the carrier plate and pulls the carrier plate in a predetermined direction. The cable guide changes the direction of the cable. The other end of the cable is connected to the drum and winds or unwinds the cable that is routed around the cable guide. The cable has a cable body and a terminal member. The terminal member is arranged at the end of the cable body. The terminal member has a terminal member body and a seat. A spring is arranged around the terminal member body. The spring seat is arranged on the side of the spring opposite to the side to which the cable is connected. The carrier plate has a housing portion. The housing portion houses the terminal member and the spring. The housing portion has a first housing portion and a second housing portion. The seat of the first housing portion is slidable. The second housing section is located on the side of the first housing section from which the cable extends, restricts movement of the spring in a direction perpendicular to the axis of the terminal member body, and has a smaller cross-sectional area perpendicular to the axis than the first housing section. The second housing section has an end face and an inner surface. The end face has a first penetration section through which the cable is inserted, and restricts movement of the terminal member beyond a predetermined level toward the side where the cable is connected. The inner surface is formed along the axis from the outer edge of the end face and is located around the spring. The inner surface has an inclined portion on the end face side of the inner surface, which is the part of the inner surface that the terminal member approaches when tension is generated in the cable, that slopes toward the axis as it approaches the end face.

This disclosure provides a cable mounting structure and window regulator that can reduce the generation of abnormal noise by suppressing axial misalignment of the spring.

Below, a window regulator will be described with reference to the drawings as an example of an object movement device according to the present disclosure, along with a description of a cable attachment structure for attaching a cable to a carrier plate. Note that the embodiment shown below is merely an example, and the object movement device and cable attachment structure are not limited to the following embodiment.

(Overview of window regulator 1)
The window regulator 1 is disposed on a door panel of a vehicle door. The window regulator 1 is a mechanism for raising and lowering a window glass W (an example of a movable object) of the vehicle. Fig. 1 is a perspective view of the window regulator 1 attached to the vehicle, as viewed from the outside of the vehicle. Fig. 2 is a perspective view of the window regulator 1 attached to the vehicle, as viewed from the inside of the vehicle.

As shown in Figures 1 and 2, the window regulator 1 includes a guide rail 2, a carrier plate 3 (an example of a moving member), a cable guide 4, a drive unit 5, and cables 6 and 7.

The guide rail 2 is arranged along the lifting direction of the window glass W (only a portion of which is shown by a dotted line). The guide rail 2 is a member that guides the carrier plate 3 in the lifting direction of the window glass W.

The carrier plate 3 holds the lower end of the window glass W. The carrier plate 3 is a member that engages with the guide rail 2 and is slidably guided in the direction in which the window glass W is raised and lowered. The carrier plate 3 rises and falls along the guide rail 2.

The cable guide 4 changes the direction of movement of the cable 6. The cable guide 4 is arranged at the upper end of the guide rail 2. The cable guide 4 is, for example, a pulley.

Drive unit 5 winds and unwinds cables 6 and 7. Drive unit 5 is located at the lower end of guide rail 2. Drive unit 5 is provided with a drum (not shown), to which the ends of cables 6 and 7 are connected.

The up-down direction when the cable guide 4 is attached to the vehicle is indicated by A. Within the up-down direction A, the upward direction toward the cable guide 4 is indicated by arrow A1, and the downward direction toward the drive unit 5 is indicated by arrow A2. Furthermore, the fore-and-aft direction of the vehicle when the cable guide 4 is attached to the vehicle is indicated by B. Within the fore-and-aft direction B, the forward direction is indicated by arrow B1, and within the fore-and-aft direction B, the rearward direction is indicated by arrow B2. Furthermore, the width direction of the vehicle, which is perpendicular to the up-and-down direction A and the fore-and-aft direction B, is indicated by C. Within the width direction C, the inward direction when the cable guide 4 is attached to the vehicle is indicated by arrow C1, and the outward direction is indicated by arrow C2.

Cable 6 is an elevation cable used to elevate carrier plate 3. One end of cable 6 is connected to carrier plate 3. Cable 6 extends upward from carrier plate 3, is wound around cable guide 4, and extends downward from cable guide 4. The other end of cable 6 is connected to the drum.

Cable 7 is a lowering cable used to lower carrier plate 3. One end of cable 7 is connected to carrier plate 3. Cable 7 extends downward from carrier plate 3. The other end of cable 7 is connected to the drum. The cable attachment structure for attaching cables 6 and 7 to carrier plate 3 will be described in detail below.

Cables 6 and 7 can be made of known materials made by twisting together multiple metal wires or resin fiber wires.

The drive unit 5 includes a drum (not shown), a motor 12, a drum housing 13, and a motor housing 14. The ends of cables 6 and 7 are connected to the drum. The drum winds and unwinds the cables 6 and 7. The motor 12 rotates the drum. The motor 12 is rotatable in both directions, rotating the drum in both directions. This causes the cables 6 and 7 connected to the drum to be wound onto or unwound from the drum. As shown in Figures 1 and 2, the motor 12 is integral with the motor housing 14. The output shaft (not shown) of the motor 12 is connected to the drum via a reduction mechanism (not shown) located in the motor housing 14, rotating the drum. The drum housing 13 houses the drum. The drum housing 13 and motor housing 14 are fastened together with fastening members such as bolts.

(Carrier plate 3)
Fig. 3 is a perspective view showing the carrier plate 3 and the cables 6, 7. Fig. 4A is a front view of the carrier plate 3. Fig. 4B is a top view of the carrier plate 3. Fig. 4C is a bottom view of the carrier plate 3. Fig. 4D is a bottom view of the carrier plate 3. The cables 6, 7 and springs 8, 9 are shown in Fig. 4A, but are omitted in Figs. 4B to 4D.

As shown in Figures 4A to 4D, the carrier plate 3 has a generally inverted triangular shape when viewed from the front. The carrier plate 3 has an ascending cable end storage section 21, a descending cable end storage section 22, an insertion section 23, an insertion section 24, and a support section 25.

As shown in FIG. 3, cable 6 is attached to the ascending cable end housing 21. Cable 7 is attached to the descending cable end housing 22. The ascending cable end housing 21 and the descending cable end housing 22 are located near the center of the carrier plate 3 in the fore-and-aft direction B. The ascending cable end housing 21 is located further forward in the forward direction B1 than the descending cable end housing 22.

Both ends of the guide rail 2 are inserted into the insertion sections 23 and 24. The insertion section 23 is located forward (B1) from the ascending cable end housing 21. The forward (B1) end 2a (see Figure 2) of the guide rail 2 is inserted into the insertion section 23. The insertion section 24 is located rearward (B2) from the descending cable end housing 22. The rearward (B2) end 2b (see Figure 2) of the guide rail 2 is inserted into the insertion section 24. This allows the carrier plate 3 to be movably supported on the guide rail 2. Support sections 25 are provided at the forward (B1) end and rearward (B2) end of the carrier plate 3. Support holes are provided in the support sections 25, and fastening members are inserted into the support holes to fasten the window glass W to the support sections 25. In this way, the carrier plate 3 supports the window glass W.

(Cables 6 and 7)
The end portions of the cables 6 and 7 attached to the carrier plate 3 have the same configuration, so the cable 6 will be taken as an example for explanation.

Figure 5 is a perspective view showing the end of the cable 6. As shown in Figure 5, the cable 6 has a cable main body 31 and a terminal member 32. The terminal member 32 is disposed at the end of the cable main body 31. The terminal member 32 has a terminal member main body 33 and a seat portion 34. The terminal member main body 33 is cylindrical. The cable main body 31 is connected to one end face of the terminal member main body 33. As shown in Figure 6, a spring 8 is disposed around the terminal member 32. The spring 8 is, for example, a coil spring. The seat portion 34 is provided on the end face of the terminal member main body 33 opposite the cable main body 31. The seat portion 34 is formed in a disk shape with a larger diameter than the terminal member main body 33. The spring 8 disposed around the terminal member main body 33 abuts against the seat portion 34. In this embodiment, the outer diameter of the seat portion 34 is larger than the outer diameter of the spring 8.

Figure 7 is a cross-sectional view along cables 6 and 7 in Figure 3. Figure 7 is a perspective cross-sectional view of the position between FF in Figure 4B. As shown in Figure 7, like cable 6, cable 7 also has a cable body 41 and a terminal member 42, and terminal member 42 has a terminal member body 43 and a seat portion 44. A spring 9 is disposed around the terminal member body 43. Spring 9 is similar to spring 8 and is, for example, a coil spring.

As shown in Figure 7, the spring 8, which is arranged around the terminal member body 33 of the cable 6, is positioned between the seat 34 and the end face 71 of the ascending cable end housing 21. When the cable 6 is pulled in the upward direction A1, it is compressed between the seat 34 and the end face 71 of the ascending cable end housing 21.

The spring 9, which is arranged around the terminal member body 43 of the cable 7, is positioned between the seat 44 and the end face 61 of the ascending cable end housing 21. When the cable 7 is pulled downward A2, it is compressed between the seat 44 and the end face 61 of the descending cable end housing 22.

(Downward cable end storage section 22)
Fig. 8A is an enlarged view of the vicinity of the descending cable end housing 22 in Fig. 4B. Fig. 8B is a perspective view of the descending cable end housing 22. Fig. 9 is a perspective cross-sectional view taken along the line D-D in Fig. 4A.

As shown in Figures 7 and 9, the descending cable end storage section 22 accommodates the terminal member 42 of the cable 7 and the spring 9. As shown in Figures 8A, 8B, and 9, the inner space of the descending cable end storage section 22 is formed in a polygonal prism shape. The inner space of the descending cable end storage section 22 has a cross section perpendicular to its central axis, the axis P, that is formed in a polygonal shape. It is preferable that the cross section of the inner space of the descending cable end storage section 22 be formed in the shape of an octagonal prism, for example. Note that in this specification, "octagon" does not only refer to a perfect octagon, but also includes approximate octagons that are visually reminiscent of an octagon.

As shown in Figure 8B, the descending cable end housing 22 has an end face 61, an inner surface 62, an opening 63, and a through-hole 64. As shown in Figure 7, the cable 7 extends in the downward direction A2 from the end face 61. The end face 61 is positioned on the downward direction A2 side. The end face 61 is positioned perpendicular to the up-down direction A.

The inner surface 62 is arranged to extend from the periphery of the end face 61 in the upward direction A1. The inner surface 62 has side portions 621 that form the sides of the polygonal cross-sectional shape. In this embodiment, the inner surface 62 is formed into an octagonal shape, resulting in eight side portions 621. The eight side portions 621 are arranged parallel to the axis P. Note that only some of the eight side portions 621 are indicated by reference numerals. The opening 63 is provided at the end of the inner surface 62 opposite the end face 61. The through-hole 64 penetrates the wall of the descending cable end housing 22. The through-hole 64 is formed through the center of the end face 61 to the outer edge of the end face 61, and then extends from that outer edge along the vertical direction A through one side portion 621 of the inner surface 62 to the opening 63. Of the side portions 621 described below, the one with the through-hole 64 formed therein is referred to as the side portion 621a. The side portion 621a is the surface of the inner surface 62 facing in the inward direction C1. The side surface portion 621a is arranged perpendicular to the width direction C.

The cable 7 is attached to the descending cable end housing 22 by passing the cable main body 41 through the through-hole 64 and inserting the terminal member 42 and spring 9 through the opening 63.

(Ascent cable end storage section 21)
Next, the ascending cable end housing 21 to which the cable 6 is attached will be described. Fig. 10A is an enlarged view of the vicinity of the ascending cable end housing 21 in Fig. 4C. Fig. 10B is a perspective view of the ascending cable end housing 21 as viewed from the inward direction C1 side. Fig. 10C is a perspective view of the ascending cable end housing 21 as viewed from the outward direction C2 side. Fig. 10D is a cross-sectional view perpendicular to the front-rear direction B. The cross-section position of Fig. 10D is the same as the perspective cross-section between E and E in Fig. 4A. Fig. 11 is a perspective cross-sectional view between E and E in Fig. 4A. Fig. 11 is a view in which a terminal member 32 and a spring 8 are added to Fig. 10D.

As shown in Figure 7, the ascending cable end storage section 21 stores the terminal member 32 of the cable 6 and the spring 8. As shown in Figures 10A to 10C, the internal space of the ascending cable end storage section 21 has a polygonal cross section perpendicular to its central axis, the axis Q. It is preferable that the cross section of the ascending cable end storage section 21 be formed, for example, in the shape of an octagonal prism. Note that in this specification, "octagon" does not only refer to a perfect octagon, but also includes approximate octagons that are visually reminiscent of an octagon.

As shown in FIG. 10B, the ascending cable end storage section 21 has an end face 71, an inner surface 72, an opening 73, and a through-hole 74. As shown in FIG. 11, the cable 6 extends in the upward direction A1 from the end face 71. The end face 71 is disposed on the upward direction A1 side. The end face 71 is disposed perpendicular to the up-down direction A.

The inner surface 72 is arranged to extend from the periphery of the end surface 71 in the downward direction A2. The opening 73 is provided at the end of the inner surface 72 opposite the end surface 71. The through-hole 74 penetrates the wall of the ascending cable end storage section 21. The through-hole 74 is formed through the center of the end surface 71 to the outer edge of the end surface 61, and then extends from that outer edge along the vertical direction A through the inner surface 72 to the opening 63.

The cable 6 is attached to the lifting cable end storage section 21 by passing the cable main body 31 through the through-hole 74 and inserting the terminal member 32 and spring 8 through the opening 73.

As shown in Figures 10B and 10C, the ascending cable end housing 21 has a first housing 51 and a second housing 52. As shown in Figure 11, the seat 34 can slide in the first housing 51. The first housing 51 is the portion of the ascending cable end housing 21 on the downward direction A2 side. The cross-sectional area of the first housing 51 along the vertical direction A is constant. The central axis of the first housing 51 coincides with the central axis of the terminal member 32 when the cable 6 is attached to the first housing 51. This coincident axis is indicated as axis Q. The outer peripheral edge of the seat 34 slides against the inner surface 75 of the first housing 51.

The first storage section 51 has a polygonal cross-sectional shape perpendicular to the axis Q. As shown in Figures 10B and 10C, the inner surface 75 has side portions 751 that form multiple side surfaces of a polygonal prism. In this embodiment, the inner surface 75 is formed into an octagonal shape, and therefore has eight side portions 751. The eight side portions 751 are arranged parallel to the axis Q. Note that only some of the eight side portions 751 are indicated by reference numerals. An opening 73 is formed at the end of the first storage section 51 opposite the second storage section 52.

As shown in Figures 10B and 10C, the second housing portion 52 is disposed on the side of the first housing portion 51 from which the cable 6 extends (upward A1 side). As shown in Figure 11, the second housing portion 52 restricts movement of the spring 8 in a direction perpendicular to the axis Q, and has a smaller cross-sectional area perpendicular to the axis Q than the first housing portion 51.

As shown in Figures 10B and 10C, the second accommodating section 52 has an end face 71 and an inner surface 76. The end face 71 has a first penetration portion 77 formed therein, through which the cable 6 is inserted. The first penetration portion 77 penetrates the end face 71 in the vertical direction A. The first penetration portion 77 is formed through the center of the end face 71 to the outer edge of the end face 71. The first penetration portion 77 is formed in a groove shape. In this embodiment, the first penetration portion 77 is formed from near the center of the end face 71 toward the inner direction C1. The end face 71 restricts movement of the terminal member 32 toward the side where the cable 6 is connected (upward direction A1) beyond a predetermined limit. The end face 71 is disposed perpendicular to the vertical direction A.

The inner surface 76 is formed along the axis o from the outer edge of the end face 71. As shown in FIG. 11 , when the cable 6 is attached to the ascending cable end storage section 21, the inner surface 76 is positioned around the spring 8. The inner surface 76 of the second storage section 52 and the inner surface 75 of the first storage section 51 form the inner surface 72 of the ascending cable end storage section 21 described above.

The second storage section 52 has a polygonal cross-sectional shape perpendicular to the axis o. As shown in Figures 10B and 10C, the inner surface 76 has side portions 761 that form the sides of the polygonal cross-sectional shape. The side portions 761 form multiple side surfaces of a polygonal prism. In this embodiment, the second storage section 52 is formed into an octagonal shape, so eight side portions 761 are provided. Note that only some of the eight side portions 761 are indicated by reference numerals.

As shown in Figures 10A to 10D, the inner surface 76 has an inclined portion 78. The inclined portion 78 is formed on one of the side surface portions 761a of the multiple side surface portions 761. As shown in Figure 11, the inclined portion 78 is inclined toward the end surface 71 of the side surface portion 761a (an example of a surface) of the inner surface 76, to which the terminal member 32 approaches when tension is generated in the cable 6, so as to approach the axis Q as it approaches the end surface 71.

The side surface portion 761a on which the inclined portion 78 is formed is the surface of the multiple side surface portions 761 facing inward in the C1 direction. All of the side surface portions 761, except for the side surface portion 761a, are formed parallel to the axis Q. Each of the side surface portions 751 of the first storage section 51 is arranged on the end face 71 side of each of the side surface portions 761 so as to correspond to each of the side surface portions 761. Each of the side surface portions 761, except for the side surface portion 761a, is arranged parallel to each of the side surface portions 751. The side surface portion 761 is positioned closer to the axis Q than the side surface portion 751. Therefore, a step 771 is formed between the side surface portion 761 and the side surface portion 751, as shown in Figures 10A to 10C.

As shown in Figure 10B, a second through-hole 79 is formed in the side portion 761a. The second through-hole 79 penetrates the side portion 761a in the width direction C. The second through-hole 79 is connected to the first through-hole 77 and is formed in a groove shape along the axis Q. The second through-hole 79 is located in the center of the side portion 761a in the front-to-rear direction B. As shown in Figures 10A and 10C, the inclined portions 78 are located so as to sandwich the second through-hole 79. The inclined portions 78 are located on both sides of the second through-hole 79 in the front-to-rear direction B.

As shown in FIG. 10C, the second through portion 79 is formed from the side portion 761a to the side portion 751a, which is located on the opposite side of the end face 61 of the side portion 761a. The second through portion 79 is connected to the opening 73. The first through portion 77 and the second through portion 79 form the above-mentioned through portion 74.

As shown in Figure 11, when tension is applied to the cable 6, the seat 8a at the end of the spring 8 on the end face 71 side comes into contact with the inclined portion 78 as the terminal member 32 moves. When tension is applied to the cable 6, the spring 8 also tends to move in the direction of arrow G (the direction between arrows A1 and C1) where the through-hole 74 is formed, following the curvature of the guide rail 2. However, because the spring 8 is in contact with the inclined portion 78, the movement of the spring 8 is restricted. This prevents the spring 8 from tilting and rotating, thereby reducing the sound of the seat 8a of the spring 8 hitting the end face 71.

(Features, etc.)
In the window regulator 1 of this embodiment, the provision of the second housing 52 in the lifting cable end housing 21 suppresses axial misalignment of the spring 8, thereby reducing the generation of abnormal noise. Furthermore, the provision of the inclined portion 78 in the second housing 52 causes the inclined portion 78 to come into contact with a portion of the seat 8a at one end of the spring 8, thereby suppressing tilt of the spring 8 and inhibiting rotation of the spring 8. This reduces the generation of noise caused by the end face 71 of the lifting cable end housing 21 hitting the seat 8a of the spring 8.

In the window regulator 1 of this embodiment, the second housing portion 52 has a polygonal cross-sectional shape perpendicular to the axis Q. This suppresses rotation of the spring 8 and reduces the occurrence of impact noise.

In the window regulator 1 of this embodiment, by providing an inclined portion 78 on the side surface portion 761a where the second through-hole 79 is formed, movement of the spring 8 in the direction in which the cable 6 is pulled can be suppressed, thereby reducing the occurrence of axial misalignment.

(Other embodiments)
Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment, and various modifications are possible without departing from the gist of the present disclosure.

(A)
In the above embodiment, a window regulator 1 that moves a window glass as an object was used as an example of an object moving device, but this is not limited to this, and the present disclosure can be applied to any device that drives an object by winding and sending out a cable using a drum.

(B)
In the above embodiment, the cross-sectional shape perpendicular to the axis Q of the inner space of the ascending cable end accommodating portion 21 is polygonal, but this is not limited to this and may be, for example, circular.

Furthermore, the cross-sectional shapes of the first storage section 51 and the second storage section 52 may be different. For example, the cross-sectional shape of the inner space of the second storage section 52 may be octagonal, and the cross-sectional shape of the inner space of the first storage section 51 may be circular.

(C)
In the above embodiment, the ascending cable end accommodating portion 21 has the inclined portion 78, and the descending cable end accommodating portion 22 does not have the inclined portion 78, but this is not limiting, and the descending cable end accommodating portion 22 may have the inclined portion 78, and the ascending cable end accommodating portion 21 may not have the inclined portion 78. Furthermore, both the ascending cable end accommodating portion 21 and the descending cable end accommodating portion 22 may have the inclined portion 78.

(D)
