Description

  The present invention relates to a flip-up type hood hinge that, when a vehicle collides with an obstacle, jumps up the rear end of the hood with the press of an actuator, and relaxes and absorbs the impact when the obstacle falls on the hood The present invention relates to a hinge cover suitable for a device and a flip-up hood hinge device.

  FIG. 13 shows a flip-up hood structure disclosed in Patent Document 1. In this hood structure, the hood 10 is interposed between the corresponding portion of the vehicle body B and supports the rear end portion of the hood 10 so that it can be opened and closed in a normal state, and when a collision load is input to the front end portion of the vehicle body. A hinge device (a hood hinge) 30 is used that enables a rear end of the hood to be flipped up by pressing a part of the constituent members with an actuating actuator 40. The hinge device 30 includes a hood side link 31, a vehicle body side link 32, an intermediate link 33 disposed between the links 31, 32, a lock piece 38 and a spring 39.

  Among these, the link 31 has one end attached to the lower surface of the hood 10 and the other end connected to one end of the intermediate link 33 by a fulcrum pin 34 so as to be rotatable. A receiving piece 43 that contacts the rod 41 of the actuator 40 is mounted on the front side of the link 31. The link 32 corresponds to a bracket attached to the vehicle body B side, and includes a rear upper U-shaped engaging portion 32a, a sliding hole 35 extending from the front side to the middle of the rear, and a downward direction from the rear end of the sliding hole 35. An extended holding portion 35a is formed. A lock piece 38 is rotatably connected to the link 32 via a pin 37. The lock piece 38 has a lock claw 38a at the tip, and is urged clockwise by a spring 39 arranged between the front side portion of the link 32 and the fulcrum pin 34 is fitted to the engagement portion 32a. The state is held by the lock claw 38a. The hood 10 is normally opened and closed around the fulcrum pin 34 in this state. Further, a guide pin 36 planted on the other end side of the intermediate link 33 is slidably engaged with the sliding hole 35. In addition, when the front end of the vehicle body collides with an obstacle such as a pedestrian, the actuator 40 operates so as to project the rod 41 instantaneously through the control unit while the sensor detects it.

As shown in FIG. 13A, the hinge device 30 as described above is rotated upward about the engaging portion 32 a by lifting the front end portion of the hood 10 as shown in FIG. On the other hand, when the vehicle collides frontward with an obstacle, as shown in FIG. 13B, the rod 41 of the actuator 40 protrudes and hits the receiving piece 43 to press the link 31 upward. Then, the lock piece 38 is pushed in a direction in which the fulcrum pin 34 pushes away the lock claw 38 a and is rotated counterclockwise against the urging force of the spring 39. As a result, the fulcrum pin 34 comes out of the engaging portion 32a, and the rear end portion of the hood 10 is flipped up. At that time, the guide pin 36 is finally engaged with the holding portion 35 a while being moved rearward of the vehicle body along the sliding hole 35. In this flip-up state, the impact when the obstacle falls on the hood can be efficiently reduced or absorbed.
JP 2005-225392 A

  In the above-described flip-up hood structure, when the hood 10 is switched from the closed state covering the engine room to the normal open state, the constituent members of the hinge device 30 are exposed as shown in FIG. Look worse. This is because, among the constituent members of the hinge device 30, the receiving piece 43, which is pressed upward by the actuator 40, is located inside the hood, so that it can be easily seen in the hood open state, resulting in an appearance deterioration factor.

  As a countermeasure, for example, it is conceivable to cover a member disposed inside the hood among the constituent members of the hinge device 30 with a dedicated cover. However, such a cover becomes expensive if it is made rigid so that it can withstand even when the rod 41 of the actuator 40 comes into contact, for example, and if a through hole for the rod is formed, the appearance characteristics are not satisfied. Further, the flip-up hood hinge device as shown in the present invention, that is, the link that is a component member of the hinge device is normally constrained via a lever, and the actuator rod is used. If the structure is such that the lever is switched to an unconstrained state when the lever is flipped up, the rod will press against the lever via the cover-corresponding portion, which causes a delay in the operation timing.

  Therefore, an object of the present invention is for a hinge that can improve the appearance characteristics without impairing the pressing operation of the actuator even if it covers the constituent members arranged inside the hood among the constituent members of the flip-up hood hinge device. It is an object of the present invention to provide a cover and a flip-up hood hinge device including the same.

  In order to achieve the above object, the hinge cover of the present invention is interposed between the hood and the vehicle body and supports the hood so that it can be opened and closed, and operates when a collision load is input to the front end of the vehicle body. The actuator is used in a hinge device that allows a hood to be lifted by pressing a part of the component member, and covers the portion of the hinge device that includes a portion that is pressed by the actuator. A contact portion that does not hinder the pressing operation is formed.

  The hinge cover described above is pressed by an actuator that operates when at least a collision load is input to the front end of the vehicle body among the components of the flip-up hood hinge device interposed between the vehicle body and the hood. It is essential that the area including the area to be covered is covered and that the abutment part that does not hinder the original pressing operation by operating the actuator is essential. Here, “food” is also called a hood. The “collision load” is usually detected by a sensor or the like provided at the front end of the hood that an obstacle has collided with the front end of the hood, and the detection signal is sent to the control unit from the control unit to the actuator. Will be sent. For example, in the case of the flip-up type hood hinge device shown in the embodiment, the “pressed portion by the actuator” corresponds to the pushing portion (23a) of the lever pressed by the rod of the actuator. When applied to a lifting hood hinge device (hood hinge), the receiving piece (43) pressed by the rod of the actuator corresponds.

Moreover, it is more preferable that the above-mentioned this invention is actualized as follows.
(1) The abutment portion is configured to be easily partitioned through a plurality of slit portions (claim 2).
(2) The contact portion is configured to be easily deformed through a plurality of slit portions (claim 3).

Thus, an abutment portion that does not interfere with the original pressing operation by operating the actuator is formed. For this reason, in the present invention, in the structure in which the hood is flipped up by pressing the structural member of the hinge device by the actuator, even if the structural member of the hinge device arranged on the inner surface side of the hood is covered, the pressing operation of the actuator is applied to the cover. Since it is performed without any trouble through the formed contact portion, the appearance characteristics can be improved without impairing the pressing operation of the actuator.

  The cover for hinges according to claim 2 can be easily separated through a plurality of slit portions as illustrated in FIGS. 1 and 2 as the contact portion of the cover that does not hinder the pressing operation of the actuator. It is the structure currently formed, and as an advantage, the design separation load requested | required by the contact part can be easily satisfied by the number of slit parts, the width dimension of the connection part between slit parts, etc.

  The cover for hinges according to claim 3 is configured to be easily deformed by a plurality of slit portions as illustrated in FIG. 9 as an abutting portion of the cover that does not hinder the pressing operation of the above-described actuator, As an advantage, the design deformation load required for the abutting portion can be easily satisfied by the number of slit portions, the slit width dimension, and the like.

  A sensor 14 is provided as a collision detection means for detecting a collision with an obstacle such as a pedestrian on the front side of the front bumper 13 and / or the hood 15 mounted on the lower side of the front end portion 10 of the vehicle body. . The sensor 14 is connected to the control unit 7 in the vehicle interior. The control unit 7 determines whether or not to raise the hood 15 according to the detection output of the sensor 14, and outputs an operation signal to the actuator 6 when determining that the hood 15 is to be raised. The actuator 6 has a push-up rod 6a, a gas generating means 6b, etc., and the gas generating means 6b generates gas in response to an operation signal from the control unit 7, and the rod 6a protrudes instantaneously by the gas pressure. is there.

(Hinge device) The left and right hinge devices 2 are interposed between the rear end side of the hood 15 and the vehicle body (the rear end side in the engine room), and support the rear end portion 15a of the hood 15 so as to be freely opened and closed. Any configuration may be employed as long as the hood rear end portion 15a can be raised by pressing a part of the constituent members with the actuator 6 described above, that is, can be flipped up. This example is embodied as shown in FIGS. Since the left and right hinge devices 2 and the left and right actuators 6 are structurally the same on the left and right sides (however, in the case of the hinge device 2, the bent shape of the first arm 20 is changed), only one will be described. The other is omitted.

  1-4, the hinge apparatus 2 has the 1st link 21, the 2nd link 22, the lever 23, and the urging | biasing spring 24 which urges | biases the lever 23 to one direction, These are vehicle bodies. Between the bracket 5 fixed to the side and the bracket 3 fixed to the hood 15 (outer panel 17 thereof) side. Accordingly, the hinge device 2 is configured as the hinge unit product 20 by the first link 21, the second link 22, the lever 23, the urging spring 24, and the bracket 3, but is regarded as the hinge unit product 20 including the bracket 5.

(Cover) The cover 4 is used in the hinge device 2 described above, and covers a portion of the constituent members of the hinge device 2 including the portion pressed by the actuator 4 and does not hinder the pressing operation of the actuator 4. 45 is formed. This example is embodied as shown in FIGS. 1, 7, and 8. In the cover 4, the position of the link insertion portion is changed between the left hinge device 2 and the right hinge device 2 so as to be on the right side or the left side. To do.

  In FIGS. 1, 7, and 8, the cover 4 is formed of a resin injection molded body, and the hinge device 2 is attached to the hood 15 side via the flange 3, and the hinge device 2 is connected to the first link 21. The container is almost covered except for the base end side. Specifically, the peripheral wall rising from the container bottom wall 4a has a slightly lower front side portion 40 disposed on the front side of the vehicle body, a rear side wall 41 disposed on the windshield side, and both side walls 42 and 43. ing. In addition, a link insertion portion 44 is formed between the rear side wall 41 and the side wall 43 so that the first link 21 can be inserted into the cover with a margin.

  A contact portion 45 is formed in the container bottom wall 4 a in a state of being partitioned by a plurality of slit portions 46. The contact portion 45 is set at a position corresponding to the rod 6 a of the actuator 6 or a position corresponding to the pressing portion 23 a of the lever 23 constituting the hinge device 2, and from the front of the link insertion portion 44 toward the side wall 42. It is formed at the displaced location. In this example, a plurality of slit portions 46 are formed at equal intervals on a circular line, and the slit portions 46 are connected to the bottom wall 4a by a breaking connection portion 45a. In terms of shape, a plurality of slit portions 46 and connection portions 45 a may be formed on the oval or square line as the contact portion 45. Further, in terms of design, as the slit portion 46 and the connection portion 45a, when the rod 6a hits the contact portion 45 as shown in FIG. 2B, the contact portion 45 does not impair the normal operation of the actuator 6. The number and length of the slit portions 46 that are easily divided from the bottom wall 4a, the width of the connection portion 45a, and the like are set.

  A plurality of mounting engaging portions 47 are provided on the inner surfaces of the side walls 42 and 43 so as to face each other. As inferred from FIGS. 8 (b) and 8 (d), each engaging portion 47 has a configuration in which an overhanging portion of an inner cavity is formed on the inner surface of the side wall, and two claw portions 48 are formed in the overhanging portion. is there. Each claw portion 48 is partitioned by a U-shaped slit portion 47a. In FIG. 7, 49a is an auxiliary mounting hole for fixing the cover 4 to the bracket 3 with bolts or the like as needed, 49b is a clearance hole for releasing a member for mounting the bracket 3 on the hood side, 49c is a positioning portion for the cover, 49d is a temporary fixing part. These are appropriately employed according to the specific cover configuration and shape.

(Operation) The mounting procedure and operation characteristics of the cover 4 will be described.
(A) The cover 4 can be easily attached to the bracket 3 on the hinge device side by the following operation. That is, for example, the cover 4 is configured so that the cover-side engagement portion 47 corresponding to the bracket both-side locking hole 34 described above is aligned with the bracket 3 as indicated by an imaginary line in FIG. When pressed against the bracket side, the claw portions 48 of the respective engaging portions 47 are pushed by the corresponding piece portions 31 and are displaced so as to reduce the amount of protrusion once. Then, it is engaged with the locking hole 34 and attached with four engaging forces. When reinforcing the mounting strength, for example, the screw member is locked to the corresponding portion of the bracket 3 from the mounting hole 49a. Thus, in this structure, since the cover member 4 is covered by the cover 4 except for the base end side of the first arm 21 among the constituent members of the hinge device 2, the appearance characteristics can be improved.

(A) In the normal state (when the collision load is not input to the vehicle body front end portion 10), the hinge device 2 lifts the front end portion of the hood 15 as schematically shown in FIG. The hood 15 is rotated from the closed state of the imaginary line to the upper direction, that is, the open state of the solid line, with the pivot 19a as the center. At this time, as shown in FIG. 3, the first link 21 is restrained to the bracket 3 side by the restricting portion 23 b of the lever 23, so that the second link 22 and the bracket 3 (and the hood 15) rotate the first link 21. It is moved as a unit in the opening direction in conjunction with

(C) On the other hand, when the vehicle 1 travels, the sensor 14 detects that an obstacle (such as a pedestrian) has collided with the front end 10 of the hood, and the detection signal is sent to the control unit 7 to perform the control. When an operation signal is transmitted from the unit 7 to the gas generating means 6b of the actuator 6, the gas generating means 6b is driven to instantly protrude the rod 6a of the actuator 6. Then, in this structure, when the rod 6a hits the cover side contact portion 45, the contact portion 45 is partitioned by the plurality of slit portions 46, so that the connecting portion 45a is broken by the pressing force of the rod 6a and the container bottom wall Easy separation from 4a. Then, as shown in FIG. 2B, the push portion 23a of the lever 23 is attached via the contact portion 52 from which the rod 6a is separated (or when the divided contact portion 52 is dropped, the rod 6a alone). It rotates against the urging force of the urging spring 24 toward the window 33, and as a result schematically shown in FIG. 6, the rear end of the hood 15 is raised in the direction of the arrow in FIG. In this flip-up state, the impact when the obstacle falls on the hood can be efficiently mitigated or absorbed at the rear end side of the hood.

  In the process of switching to the hood flip-up mode of FIG. 6, when the lever device 23 is pushed upward from the state shown in FIG. The side restricting portion 23bb is rotated in the opposite direction to the pressing portion 23a, and as a result, the second link 22 is moved away from the bracket 3 with the pivot 19e of the second link 22 as a fulcrum.

(First Modification) The modification of FIG. 9 is the same as the above embodiment except for the configuration of the contact portion of the cover 4 to which the rod 6a of the actuator 6 abuts. Will be omitted, and the changes will be described in detail. That is, the contact portion 50 is formed by setting the corresponding portion of the container bottom wall 4a to a thin circular portion, and forming the thin circular portion into a plurality of elastic piece portions 51 that can be easily deformed with the base end as a fulcrum. . In other words, each elastic piece portion 51 is defined by a plurality of slit portions 52 that extend radially from the center hole of the thin circular portion toward a circle line. When each elastic piece 51 is pressed against the rod 6a as shown in FIG. 9 (b), the elastic piece 51 is deformed upward with the base end on the circular line as a fulcrum, thereby allowing the rod 6a to pass. In other words, in this configuration, when the rod 6a of the actuator 6 hits each elastic piece 51 constituting the abutting portion 50, each elastic piece 51 easily does not impair the normal operation of the actuator 6. The number of the elastic piece portions 51 and the slit portions 52 is set so as to be deformed.

(Second Modification) The modification of FIG. 10 is the same as the above-described embodiment except that the configuration of the contact portion with which the rod 6a of the actuator 6 abuts is further changed. A description will be given in detail by omitting the duplicated description with reference numerals. That is, the abutting portion 53 is formed by easily deforming a corresponding portion of the container bottom wall 4a by a bellows configuration, and more specifically, a circular central portion 55 larger in diameter than the rod 6a, and the central portion And a bellows portion 54 formed around 55. When the central portion 55 is pressed against the rod 6a as shown in FIG. 10B, the contact portion 53 presses the lever-side pressing portion 23a with the extending action of the bellows portion 54. In other words, in this configuration, when the rod 6 a of the actuator 6 hits the central portion 55 constituting the contact portion 53, the bellows portion 54 is easily extended without impairing the normal operation of the actuator 6. Shape etc. are set.

(Third Modification) The modification of FIG. 11 is the same as the above-described embodiment except that the configuration of the contact portion of the above-described cover 4 on which the rod 6a of the actuator 6 abuts is further changed. A description will be given in detail by omitting the duplicated description with reference numerals. That is, the abutting portion 56 is formed by detaching the corresponding portion of the container bottom wall 4a by a cap configuration, and has an engaging portion 57 having a concave cross section formed around the abutting portion. The engaging portion 57 is detachably fitted to the locked portion 4b having a convex cross section formed on the inner periphery of the opening provided in the container bottom wall 4a corresponding to the contact portion 56. The contact portion 56 is formed in a circular shape, but may be formed in an ellipse or a square shape. Further, in terms of design, when the engaging portion 57 and the locked portion 4b are configured to be engaged, when the rod 6a of the actuator 6 hits the abutting portion 56 as shown in FIG. The portion 56 is set so as to be easily detached from the container bottom wall 4a without impairing the normal operation of the actuator 6.
