Description

Opening/closing body structure of motor vehicle and method for manufacturing opening/closing body structure

Technical Field

The present invention relates to an opening/closing body structure of a motor vehicle and a method for manufacturing the opening/closing body structure.

The present application claims priority based on japanese patent application No. 2020-140903 filed on 8/24/2020, and the contents thereof are incorporated herein.

Background

As an opening/closing body structure of an automobile, for example, a structure is known in which a front portion of a side door is supported by a vehicle body via a door hinge, and a rear portion is supported by the vehicle body by a door lock device and a receiver mechanism in a state in which the side door is closed. An upper cross member and a lower cross member are provided in the side door, for example, as reinforcing members. The front end portion of the upper cross member is supported by the vehicle body by a door hinge, and the rear end portion of the upper cross member is supported by the vehicle body by a door lock device. The front end portion of the lower cross member is supported by the vehicle body by a door hinge, and the rear end portion of the lower cross member is supported by the vehicle body by a receiver mechanism.

In this case, for example, an insertion member (hereinafter, referred to as a hook) is provided at the rear end portion of the lower cross member, and a receiving member (hereinafter, referred to as a receiver) is provided at the rear side pillar (C pillar) of the vehicle body. The hooks are inserted into the receptacles when the side door is closed.

When an impact load, for example, a side impact load is input from a side vehicle in a state where the hook is fitted into the receiver, the hook is engaged with the receiver by the input impact load. Accordingly, it is possible to suppress a situation in which a part of the input impact load is dispersed to the lower cross member and the rear side pillar is deformed toward the vehicle cabin (for example, refer to patent document 1).

Problems to be solved by the invention

In addition, it is considered that a deviation occurs when a side door is generally attached (assembled) to a vehicle body. Therefore, in a state where the hook is fitted into the receptacle, a gap caused by assembly tolerance or the like needs to be secured between the receptacle and the hook.

However, in the case where a gap is secured between the receiver and the hook, when an impact load is input due to, for example, a side collision, a time delay is considered to occur before the hook engages with the receiver. Therefore, it is difficult to appropriately suppress deformation of the rear side pillar, the center pillar, and the door (i.e., the vehicle body) toward the vehicle cabin due to the impact load.

The present invention provides an opening/closing body structure of a motor vehicle and a method for manufacturing the opening/closing body structure, which can suitably suppress deformation of a vehicle body toward a vehicle cabin due to an impact load input to the vehicle.

Means for solving the problems

The present invention adopts the following structure.

(1) The opening/closing body structure of a motor vehicle according to the present invention includes: an opening/closing body provided in an opening portion of a vehicle body so as to be openable and closable; a hook provided on one of the opening/closing body and the vehicle body; and a receiver provided on the other of the opening/closing body and the vehicle body so as to engage with the hook, the receiver including a pin group having a plurality of pins supported so as to be movable forward and backward with respect to an entering direction of the hook and so as to be adjacent to each other.

According to the configuration of the above-described aspect (1), the receiver is provided with a pin group having a plurality of pins. The plurality of pins are supported so as to be movable in a direction of insertion of the hooks and so as to be adjacent to each other while being in contact with each other. Thus, the opening/closing body is closed, the hooks are abutted against a part of the plurality of pins, and the hooks press in the abutted part of the pins. Thus, the whole circumference of the hook is contacted in a surrounded state by the surrounding pins adjacent to a part of the pins.

Therefore, even if a gap due to assembly tolerance or the like is set between the receiver housing and the hook, the gap between the hook and the receiver housing can be buried by the adjacent surrounding pins. That is, the hook can be held in contact with the receptacle. Thus, when an impact load is input to the vehicle due to, for example, a collision or a stress in a state where the hook is fitted into the receiver, the hook and the receiver can be quickly engaged (locked) by the input impact load, and the impact load can be quickly dispersed from each column to the opening/closing body. Therefore, deformation of the vehicle body toward the vehicle cabin due to the impact load input to the vehicle can be suitably suppressed.

Here, for example, in the case where the opening/closing body is a side door, a hook is provided on a door cross member of the side door, and a receiver is provided on the pillar. Therefore, for example, when an impact load due to a side collision is input from the side of the vehicle, the hook and the receiver can be quickly engaged (locked) by the input impact load, and the impact load can be quickly dispersed from each pillar to the door cross member. This can suitably suppress deformation of the pillar toward the vehicle cabin due to an impact load input to the vehicle.

(2) In the aspect of (1) above, the pins of the pin group may have a circular or polygonal cross section, and the plurality of pins may be supported in a dense honeycomb shape by being in contact with adjacent pins.

According to the configuration of the above-described aspect (2), the cross section of the pin is formed in a circular shape or a polygonal shape. Further, the plurality of pins are supported in the most dense honeycomb shape by the contact of the adjacent pins. Thus, the gap between the hook and the receptacle can be further suitably filled with adjacent surrounding pins. Thus, the receiver and the hook can be used to allow for a deviation that occurs when the opening/closing body is mounted (assembled) to the vehicle body.

It is particularly preferred that by forming the cross section of the pin as a hexagon in a polygon, the gap between the hook and the receptacle can be suitably filled with adjacent surrounding pins.

(3) In the aspect of (1) or (2) above, the receiver may include: a housing portion housing the pin group; and a flange portion provided in the housing portion and attached to the vehicle body.

According to the configuration of the aspect (3), the receiver is configured to be a simple structure in which the housing portion is attached to the vehicle body by the flange portion by the housing portion supporting pin group. In addition, by housing the pin group in the housing portion and attaching the flange portion to the vehicle body, the attachment work of the receiver can be facilitated.

(4) In the aspect of (3) above, the pin group may include: a plate fixed to an inside of the housing portion; a support rod which passes through the through hole of the plate and is mounted on the pin; and a spring fitted to the support rod and biasing the pin to a support position.

According to the configuration of the above (4), the support rod is inserted into the through hole of the plate, and the pin is attached to the inserted support rod. The plate is secured to the interior of the housing portion. The spring is fitted to the support rod, and the pin is biased to the support position by the elastic force of the spring.

Thus, the plurality of pins can be supported by the housing portion via the plate so as to be movable forward and backward in the direction of the hook entry and so as to be adjacent to each other without gaps (for example, in a honeycomb shape).

(5) In the aspect of (4) above, in the pin group, the pin may be pressed against the hook by the entrance of the hook, so that the hook is accommodated in the housing portion against the urging force of the spring, and the pin may return to the supporting position under the urging force of the spring by the withdrawal of the hook.

According to the configuration of the above (5), the hook is accommodated in the housing portion by the hook being brought into contact with the pin against the urging force of the spring. In addition, by withdrawing the hook, the pin is returned to the supporting position under the force of the spring. Thus, in a state where the hook is withdrawn, the appearance of the pin group (i.e., the receiver) can be ensured. Thus, the opening/closing body structure of the motor vehicle can be applied to, for example, a door, a trunk, a hood, and the like for opening/closing an opening of a normal motor vehicle. Further, by applying the opening/closing body structure of the motor vehicle to the door, the trunk, the hood, and the like, the impact load due to the collision can be appropriately dispersed to the door, the trunk, the hood, and the like, and deformation to the vehicle cabin of the vehicle body can be suppressed.

(6) In the aspect of the above (4) or (5), the support rod may have: a shaft portion that passes through the through hole, and has a tip end portion attached to the pin, and in which the spring interposed between the pin and the plate is fitted and attached; and a head portion formed at a base end portion of the shaft portion on the opposite side of the tip end portion, the head portion being locked to the plate under the urging force of the spring.

According to the configuration of the above (6), the shaft portion of the support rod is inserted through the through hole of the plate, and the tip end portion of the shaft portion is attached to the pin. The spring fitted to the shaft is interposed between the pin and the plate. The head portion is formed at a base end portion of the shaft portion opposite to the distal end portion, and is locked to the plate by the urging force of the spring.

Thus, the support bar (i.e., the pin) can be supported by the plate without being pulled out of the through hole of the plate.

(7) In any one of the aspects (1) to (6), the opening/closing body may be provided with a cross member that reinforces a main body that covers the opening, and the hook may include: a first hook portion provided at a portion of the cross member corresponding to the receiver in a state where the opening/closing body is closed; and a second hook portion extending from the first hook portion toward the receiver in a state where the opening/closing body is closed, the hook being formed in an L-shape in cross section by the first hook portion and the second hook portion.

According to the configuration of the above (7), the first hook portion of the hook is directly provided to the cross member without interposing the bracket, for example. Thus, for example, when an impact load due to a collision is input to the vehicle, the input impact load can be quickly transmitted and dispersed to the cross member via the hook. This can suitably suppress deformation of the vehicle body toward the vehicle cabin due to an impact load input to the vehicle.

The first hook portion and the second hook portion are formed in an L-shape in cross section, and the second hook portion extends toward the receiver.

Here, when an impact load is input to the vehicle due to, for example, a collision or the like, the cross member is stretched in the longitudinal direction by the input impact load. Therefore, considering the load in the direction in which the hooks are bent, the second hook portion jumps up from the receiver.

The gap between the second hook and the receptacle is then filled with a plurality of pins. Therefore, when the cross member is stretched in the longitudinal direction, the second hook portion is supported by the plurality of pins, and the hooks can be made less flexible. This can prevent the second hook from jumping up from the receiver when the cross member is stretched in the longitudinal direction. Therefore, the impact load can be quickly dispersed to the cross member, and deformation of the vehicle body toward the vehicle cabin due to the impact load input to the vehicle can be suitably suppressed.

(8) In the aspect of (7) above, the opening/closing body may be a side door provided with the cross member in the up-down direction, the front and rear portions of the side door may be supported by the vehicle body by a door hinge and a door locking device, respectively, so that the side door opens and closes the opening formed in the side portion of the vehicle body, the front and rear ends of the cross member in the upper side may be supported by the vehicle body by the door hinge and the door locking device in a state in which the side door is closed, the rear end portion corresponding to the receiver may be provided with the hook in a state in which the side door is closed, and the front end portion of the cross member in the lower side and the hook may be supported by the vehicle body by the door hinge and the receiver, respectively.

According to the configuration of the aspect (8), the front end portion of the upper cross member is supported by the vehicle body via the door hinge, and the rear end portion of the upper cross member is supported by the vehicle body via the door lock device. A hook is provided at the rear end portion of the lower cross member, and the front end portion is supported by the vehicle body via a door hinge, and the hook is supported by the vehicle body via a receiver.

Thus, for example, when an impact load due to a collision is input to the vehicle, the input impact load can be quickly transmitted to the upper side cross member via the door lock device and to the lower side cross member via the receiver and the hook. Accordingly, the input impact load can be rapidly dispersed in the upper side cross member and the lower side cross member, and deformation of the vehicle body (i.e., the pillar) toward the vehicle cabin due to the impact load input to the vehicle can be suitably suppressed.

(9) In any one of the aspects (1) to (8), in the pin group, a tip of the pin facing the outside of the vehicle body may be disposed along the surface of the vehicle body in a state where the hook is withdrawn from the receptacle.

According to the configuration of the above-described aspect (9), the tips of the plurality of pins are arranged along the surface of the vehicle body in a state where the hooks are withdrawn from the receiver. The plurality of pins are completely aligned without gaps (e.g., in a honeycomb shape) in such a manner as to be adjacent to each other in contact. This makes it possible to provide a receiver for a motor vehicle without affecting the appearance.

(10) The method for manufacturing an opening/closing body structure of a motor vehicle according to the present invention includes: an opening/closing body provided in an opening portion of a vehicle body so as to be openable and closable; a hook provided on one of the opening/closing body and the vehicle body; and a receiver provided on the other of the opening/closing body and the vehicle body so as to engage with the hook, the receiver including: a housing portion provided on the other of the opening/closing body and the vehicle body; and a pin group which is housed in the housing portion and has a plurality of pins supported so as to be movable forward and backward with respect to an entering direction of the hook and so as to be adjacent to each other in contact with each other, wherein the method for manufacturing the opening/closing body structure of the motor vehicle includes the steps of: a first step of assembling the pin group by supporting the plurality of pins on a plate so as to be movable forward and backward in the direction of the hook and so as to be adjacent to each other in contact with each other; and a second step of accommodating the pin group in the housing portion and fixing the plate to the housing portion.

According to the manufacturing method of the aspect of the above (10), in the first step, the plurality of pins are supported by the plate so as to be movable forward and backward with respect to the entering direction of the hooks and so as to be adjacent to each other by assembling the pin group. Next, in the second step, the pin group is accommodated in the housing portion, and the plate is fixed to the housing portion. Thus, the plurality of pins can be simply accommodated in the housing portion, and the receiver can be easily manufactured.

Effects of the invention

According to the aspect of the present invention, the hook is quickly engaged with the receiver under the impact load input to the vehicle, and the impact load can be quickly dispersed to the opening/closing body. This can suitably suppress deformation of the vehicle body toward the vehicle cabin due to an impact load input to the vehicle.

Detailed Description

An opening/closing body structure of an automobile and a method for manufacturing the opening/closing body structure according to an embodiment of the present invention will be described below with reference to the drawings. In the drawing, arrow FR indicates the front of the vehicle, arrow UP indicates the upper side of the vehicle, and arrow LH indicates the left side of the vehicle.

< vehicle >

As shown in fig. 1, a vehicle 10 is, for example, an automobile, and includes a body side portion (side portion of the body) 12, a front opening portion (opening portion) 13, a rear opening portion (opening portion) 14, a front door structure (opening/closing structure of the automobile) 15, and a rear door structure (opening/closing structure of the automobile) 16.

The vehicle body side portion 12 constitutes, for example, a left side portion (side portion) of the vehicle body 11. The vehicle body side portion 12 includes, for example, a rocker 21, a front pillar 22, a center pillar 23, a rear side pillar (pillar) 24, and a roof rail 25.

The front opening 13 is formed into a substantially rectangular opening by, for example, the front pillar 22, the center pillar 23, the roof rail 25, and the rocker 21. The front opening 13 is configured to support a front door structure 15 as an openable and closable structure.

The rear opening 14 is formed in the vehicle body rear of the front opening 13. The rear opening 14 is formed in a substantially rectangular shape by, for example, a center pillar 23, a rear side pillar 24, a roof rail 25, and a roof rail 21. The rear opening 14 serves as an opening/closing body structure and supports the rear door structure 16 to be opened and closed.

The front door structure 15 and the rear door structure 16 are substantially identical in structure. Accordingly, the rear side door structure 16 will be described in detail below, and the detailed description of the front side door structure 15 will be omitted.

< rear side door Structure >

The rear side door structure 16 includes, for example, a side door (opening/closing body) 31, a first door hinge (door hinge) 32, a second door hinge (door hinge) 33, a door lock device 34, and a receiver mechanism 35.

The side door 31 is a door that opens and closes the rear opening 14. The side door 31 includes, for example, a door body (main body) 36, a first cross member 37, a second cross member (cross member, upper cross member) 38, and a third cross member (cross member, lower cross member) 39.

The door main body 36 is formed in a shape that covers the rear opening 14 in a state where the side door 31 is closed. The door main body 36 is shown with the outer door panel removed for ease of understanding of the structure. A first cross member 37, a second cross member 38, and a third cross member 39 are provided in the door body 36, for example. The first cross member 37, the second cross member 38, and the third cross member 39 are reinforcing members that reinforce the door main body 36, and are formed, for example, by bending along the outer door panel.

The first cross member 37 extends from, for example, a front portion 36a of the door main body 36 toward the vehicle body rear along the body belt line 41 to a rear portion 36b of the door main body 36.

The front end portion 38a of the second cross member 38 is disposed in the vicinity of the lower portion of the front end portion 37a of the first cross member 37. The second cross member 38 extends toward the rear of the vehicle body at a downward slope from the front portion 36a to the rear portion 36b of the door body 36, for example.

The third beam 39 is disposed along the second beam 38, for example, below the second beam 38 at a relatively large interval. The third cross member 39 extends toward the rear of the vehicle body at a downward slope from the front portion 36a to the rear portion 36b of the door body 36, for example.

As shown in fig. 1 and 2, the front end portion 38a of the second cross member 38 and the front portion 36a of the door main body 36 are rotatably supported by the center pillar 23 via the first door hinge 32. The front end 39a of the third cross member 39 and the front portion 36a of the door main body 36 are rotatably supported by the center pillar 23 via the second door hinge 33.

Thus, the side door 31 is provided to the center pillar 23 via the first door hinge 32 and the second door hinge 33 so as to be openable and closable.

The first door hinge 32 and the second door hinge 33 have the same structure as those of a door hinge used in a general motor vehicle, and thus detailed description thereof is omitted.

A latch mechanism 43 of the door lock device 34 is provided at the rear of the side door 31. Specifically, the latch mechanism 43 is provided, for example, at the rear end portion 38b of the second cross member 38 and the rear portion 36b of the door main body 36 (specifically, at the rear center portion in the up-down direction of the rear portion 36 b). The latch mechanism 43 is locked to a striker (not shown) of the rear pillar 24 in a state where the side door 31 is closed.

That is, in a state where the side door 31 is closed, the front end portion 38a of the second cross member 38 is supported by the center pillar 23 via the first door hinge 32, and the rear end portion 38b of the second cross member 38 is supported by the rear side pillar 24 via the door locking device 34. Thereby, the side door 31 is kept in a state of being closed by the door locking device 34.

The door locking device 34 (i.e., the latch mechanism 43 and the striker) has the same structure as that of a door locking device used in a normal motor vehicle, and therefore, a detailed description thereof is omitted.

In addition, a hook 45 of the receiver mechanism 35 is provided at the rear of the side door 31.

< acceptor mechanism >

As shown in fig. 1 to 3, the receiver mechanism 35 includes a hook 45 and a receiver 46.

The hook 45 is provided, for example, at the rear end 39b of the third cross member 39 and the rear portion 36b of the door main body 36 (specifically, at the rear lower portion in the up-down direction in the rear portion 36 b). The rear end portion 39b of the third cross member 39 corresponds to the receiver 46 in a state where the side door 31 is closed. The hook 45 has a first hook portion 48 and a second hook portion 49.

The first hook 48 is attached to the rear end 39b of the third cross member 39 and the rear portion 36b of the door main body 36 (specifically, the upper and lower rear portions of the rear portion 36 b) by a pair of bolts 51 and nuts 52, for example. That is, the first hook 48 is provided directly at the rear end 39b of the third cross member 39 without interposing a bracket between the rear end 39b of the third cross member 39 and the first hook 48, for example.

The first hook 48 is disposed at a position corresponding to a receiver 46 described later in a state where the side door 31 is closed.

The second hook portion 49 extends from a distal end portion 48a of the first hook portion 48 toward a receiver 46 (described later) in a state where the side door 31 is closed, for example. The second hook portion 49 is formed in, for example, a rectangular shape in cross section.

The hook 45 is formed of a first hook portion 48 and a second hook portion 49 in an L-shape in cross section.

The receiver 46 is provided on the rear pillar 24 so as to engage with the second hook portion 49 of the hook 45 in a state where the side door 31 is closed. The receiver 46 includes a housing portion 55, a flange portion 56, and a pin group 57.

As shown in fig. 3 to 5, the housing portion 55 includes a housing peripheral wall 58 and a housing bottom 59.

The housing peripheral wall 58 has, for example, a pair of long walls 61 and a pair of short walls 62. The pair of long walls 61 are arranged in parallel at a distance from each other at positions opposed to each other. One short wall 62 of the pair of short walls 62 is formed at one end of the pair of long walls 61, and the other short wall 62 of the pair of short walls 62 is formed at the other end of the pair of long walls 61.

The case peripheral wall 58 is formed into a rectangular frame in cross section by a pair of long walls 61 and a pair of short walls 62. A housing bottom 59 is integrally formed at the bottom side of the housing peripheral wall 58. A bottom opening 59a is formed in the case bottom 59, for example.

The housing portion 55 has a space in which a top portion 55a is opened and a pin group 57 (described later) is accommodated in the interior 63. The housing 55 is formed so as to be receivable in a post interior 65 of the rear post 24 from an opening 24a of the rear post 24.

The flange portion 56 protrudes outward from, for example, the top portion 55a of the housing portion 55 with respect to the housing peripheral wall 58. Mounting holes 66 are formed through the flange 56 at positions corresponding to the pair of short walls 62.

The flange portion 56 is in contact with the surface (the surface of the vehicle body)) 24b of the rear side pillar 24 in a state where the housing portion 55 is received in the pillar interior 65 from the opening 24a of the rear side pillar 24. In this state, the bolts 67 pass through the pair of mounting holes 66 and are inserted into the mounting holes 68 of the rear side posts 24. The bolt 67 inserted into the mounting hole 68 is screw-coupled with the nut 69.

Thus, the flange portion 56 (i.e., the receiver 46) is mounted to the rear side post 24 with a pair of bolts 67. The housing 55 accommodates a pin group 57.

The pin group 57 includes a plate 72, a plurality of support rods (screws) 73, a plurality of pins 74, and a plurality of springs 75.

The plate 72 is, for example, a resin material, and is formed in a rectangular plate shape in plan view so as to be capable of being pushed into the inner surface 58a of the case peripheral wall 58. Thus, the plate 72 is accommodated at a predetermined position in the interior 63 of the housing 55 from the opening of the top 55a of the housing 55. Thus, the plate 72 is pressed into the inner surface 58a of the case peripheral wall 58, for example, and fixed to a predetermined position in the interior 63 of the case 55. In this state, the front surface 72a of the plate 72 is disposed on the opening side of the housing portion 55, and the rear surface 72b of the plate 72 is disposed on the housing bottom portion 59 side.

In the embodiment, the plate 72 is pressed into the housing portion 55, but the present invention is not limited to this. As another example, the plate 72 may be fitted into and fixed to the groove portion of the case peripheral wall 58, or the plate 72 may be fixed to the case peripheral wall 58 by fastening a connecting member such as a bolt.

The plate 72 has a plurality of through holes 77. The plurality of through holes 77 are formed in a circular shape, for example, and penetrate from the front surface 72a to the rear surface 72b of the plate 72. Hereinafter, the surface 72a of the plate 72 is also sometimes referred to as "plate surface 72a", and the back surface 72b of the plate 72 is sometimes referred to as "plate back surface 72b".

The plurality of through holes 77 are arranged in a honeycomb shape over the entire area of the plate 72, for example. The support rods 73 penetrate through the plurality of through holes 77.

The support rod 73 has a shaft portion 78 and a head portion 79. The shaft portion 78 is, for example, a rod formed in a cylindrical shape, and has a screw portion 78a at a tip end portion. A head 79 is formed at a base end portion of the shaft portion 78 on the opposite side of the screw portion 78a. The head 79 protrudes in a radial direction perpendicular to the axis of the shaft 78, is larger than the shaft 78, and is formed larger than the through hole 77.

Here, the screw portion 78a of the support rod 73 passes through the through hole 77 from the plate back surface 72b side, and the support rod 73 protrudes from the plate surface 72a side toward the opening (i.e., the top portion 55 a) of the housing portion 55. In this state, the head 79 is in contact with the plate back surface 72b, and the support rod 73 is supported so as not to be pulled out from the through hole 77 to the opening side of the housing portion 55.

A spring 75 is fitted and attached to a shaft portion 78 protruding from the through hole 77 to the plate surface 72a side from the screw portion 78a side. The spring 75 is, for example, a compression coil spring formed so as to be fitted to the shaft 78.

The threaded portion 78a of the shaft portion 78, for example, protruding from the spring 75 is screwed into the threaded hole 74a of the base end portion of the pin 74. Thus, shaft portion 78 is mounted coaxially with pin 74.

The pin 74 is a rod formed of, for example, a metal material and having a circular cross section, and protrudes in a radial direction orthogonal to the axis of the shaft 78 to be larger than the shaft 78. The spring 75 is interposed between the base end portion of the pin 74 and the surface 72a of the plate 72 in a compressed state.

The pin 74 is biased toward the opening of the housing portion 55 by the force of the spring 75, and the head 79 of the support lever 73 is locked to the plate back surface 72b. The head 79 is locked to the plate back surface 72b, whereby the support rod 73 can be prevented from being pulled out of the through hole 77 of the plate 72. Thus, the support rod 73 is supported by the plate 72, and the pin 74 is disposed at the support position.

In this way, the plurality of pins 74 are arranged at the supporting positions in a state where the plate 72 is fixed to the housing portion 55 by press-fitting. In this state, the distal ends 74b of the plurality of pins 74 on the opening side of the housing portion 55 face the outside of the rear side post 24, and the plurality of pins 74 are arranged (aligned) along the surface 24b of the rear side post 24.

The plurality of pins 74 are pressed against the inner portion 63 of the housing portion 55 with respect to the entering direction of the second hook portion 49 (i.e., the axial direction of the support rod 73) as will be described later. Thereby, the plurality of pins 74 are supported so as to be movable from the support position toward the plate 72 against the urging force of the springs 75.

As shown in fig. 5 and 6, the plurality of pins 74 are supported (filled) in the most dense honeycomb shape by, for example, adjacent pins 74 being in contact with each other. Specifically, the plurality of pins 74 are arranged in a dense honeycomb shape by, for example, arranging one of the distances between centers of the adjacent pins 74 so as to be D/2 with respect to the diameter D of the cross-sectional circle.

That is, the plurality of pins 74 of the pin group 57 are movable forward and backward with respect to the entry direction of the second hook portion 49, and the plurality of pins 74 having a honeycomb shape without gaps are supported by the housing portion 55 via the plate 72. The arrangement of the plurality of pins 74 is not limited to the honeycomb shape.

Returning to fig. 3 to 5, the receiver 46 is configured to have a simple structure in which the pin group 57 is supported in the inner space of the housing portion 55, and the housing portion 55 is attached to the rear post 24 by the flange portion 56.

Further, by housing the pin group 57 in the housing portion 55 and attaching the flange portion 56 to the rear post 24, the attachment work of the receiver 46 can be facilitated.

As shown in fig. 7, when the side door 31 is closed in the arrow a direction, the second hook portion 49 of the hook 45 enters the pin group 57. The second hook 49 is abutted against the tip 74b of some of the pins 74. The tip 74b of the pin 74 of the portion where the second hook portion 49 abuts is pressed against the plate 72 by the second hook portion 49.

The pin 74 pressed against the second hook portion 49 is moved from the supporting position toward the plate 72 against the urging force of the spring 75 by the pressing force of the second hook portion 49. The pin 74 pressed against the second hook portion 49 moves toward the plate 72, and the second hook portion 49 is accommodated in the interior 63 of the housing portion 55. Thus, the entire circumference of the second hook portion 49 is contacted in a surrounded state by the surrounding pins 74 adjacent to a part of the pins 74.

Accordingly, even if a gap due to assembly tolerance or the like is set between the receiver 46 and the hook 45, the gap between the second hook portion 49 and the receiver 46 can be buried by the surrounding pin 74 adjacent to a part of the pin 74. That is, the second hook portion 49 is supported by the surrounding pin 74 adjacent to a part of the pin 74. Thus, the second hook portion 49 can be held in contact with the receptacle 46.

Here, in a state where the second hook portion 49 is fitted into the receiver 46, for example, an impact load F1 is input from the left side to the vehicle 10 due to a side collision or stress. In this case, the second hook 49 can be quickly engaged (locked) with the receiver 46 by the input impact load F1. Thus, a part of the impact load F1 can be quickly dispersed as the load F2 to the side door 31 (specifically, the third cross member 39). Accordingly, deformation of the vehicle body 11 (in particular, the rear side pillar 24) toward the vehicle cabin due to the impact load F1 input to the vehicle 10 can be appropriately suppressed.

The first hook portion 48 of the hook is provided directly at the rear end portion 39b of the third cross member 39 without interposing a bracket therebetween, for example. Therefore, for example, when the impact load F1 caused by a collision is input to the vehicle 10 from the left side, a part of the input impact load F1 can be quickly dispersed as a load F2 to the side door 31 (specifically, the third cross member 39) via the hook 45.

This can further suitably suppress deformation of the vehicle body 11 (in particular, the rear pillar 24) toward the vehicle cabin due to the impact load F1 input to the vehicle 10.

The hook 45 is formed in an L-shaped cross section by a first hook portion 48 and a second hook portion 49, and the second hook portion 49 extends toward the receiver 46.

Here, when the impact load F1 is input from the left side to the vehicle 10 due to, for example, a collision or the like, the third cross member 39 is stretched toward the front (longitudinal direction) of the vehicle body as indicated by an arrow B. Therefore, considering the load F3 in the bending direction acting on the hook 45, the second hook portion 49 jumps from the receiver 46.

Then, the gap between the second hook portion 49 and the receiver 46 is buried by the surrounding pin 74 adjacent to the pin 74 of the portion where the second hook portion 49 abuts. Therefore, when the third cross member 39 is pulled toward the front of the vehicle body as indicated by arrow B, the second hook portion 49 can be supported by the surrounding pins 74 adjacent to a part of the pins 74, and the hook 45 can be made less flexible.

Thus, when the third cross member 39 is pulled, the second hook portion 49 is prevented from jumping up from the receiver 46, and a part of the impact load F1 can be quickly dispersed as a load F2 to the third cross member 39. Therefore, the deformation of the vehicle body 11 (the rear pillar 24) toward the vehicle cabin due to the impact load F1 input to the vehicle 10 can be further suitably suppressed.

As shown in fig. 1 and 7, the front end portion 38a of the second cross member 38 is supported by the center pillar 23 via the first door hinge 32. In addition, in a state where the side door 31 is closed, the rear end portion 38b of the second cross member 38 is supported by the door lock device 34 on the rear side pillar 24.

The front end 39a of the third cross member 39 is supported by the center pillar 23 via the second door hinge 33. In a state where the side door 31 is closed, the hook 45 is provided at the rear end portion 39b corresponding to the receiver 46 (specifically, the pin group 57). Thus, the third cross member 39 is supported at the front end 39a by the second door hinge 33 on the center pillar 23 and at the rear end 39b by the receiver mechanism 35 on the rear side pillar 24 in a state where the side door 31 is closed.

Thus, the front portion of the side door 31 is supported by the center pillar 23 via the first door hinge 32 and the second door hinge 33, and the rear portion of the side door 31 is supported by the rear side pillar 24 via the door locking device 34 and the receiver mechanism 35, so that the side door 31 opens and closes the rear opening 14.

As described above, according to the opening/closing body structure of the motor vehicle of the embodiment, for example, when the impact load F1 caused by the side collision is input to the vehicle 10 from the left side, a part of the input impact load F1 can be promptly dispersed to the second cross member 38 via the door lock device 34. Further, a part of the input impact load F1 can be quickly dispersed to the third cross member 39 via the hook 45.

That is, the input impact load F1 can be quickly dispersed to the second beam 38 and the third beam 39. This can further suitably suppress deformation of the vehicle body 11 (i.e., the rear pillar 24) toward the vehicle cabin due to the impact load F1 input to the vehicle 10.

In addition, as shown in fig. 6 and 8, the plurality of pins 74 are supported in the most dense honeycomb shape by the adjacent pins 74 being in contact with each other. Thus, the gap between the second hook portion 49 and the receiver 46 can be suitably filled by the surrounding pin 74 adjacent to the pin 74 of the portion where the second hook portion 49 abuts.

Here, it is considered that, for example, a deviation occurs when the side door 31 is attached (assembled) to the vehicle body 11 (i.e., the center pillar 23) (see fig. 1). Even in this case, the second hook 49 can be held in a state of contacting the receiver 46 by the surrounding pins 74 adjacent to the part of the pins 74 against which the second hook 49 abuts.

That is, the deviation generated when the side door 31 is mounted to the vehicle body 11 (i.e., the center pillar 23) can be allowed by the receiver 46 and the hook 45.

In the embodiment, an example in which the cross section of the pin 74 is formed in a circular shape is described, but the present invention is not limited thereto. As another example, the cross section of the pin 74 may be formed into a polygonal shape, for example. In particular, it is preferable that the pin 74 is formed in a hexagonal cross section, so that the gap between the pin 74 and the second hook 49 can be further suitably filled with the surrounding pin 74 adjacent to a part of the pin 74 that is in contact with the second hook 49.

As shown in fig. 5 and 7, when the side door 31 is opened in the arrow C direction, the second hook 49 is retracted from the pin group 57. Thus, the pin 74 of the portion against which the second hook portion 49 abuts returns to the supporting position by the urging force of the spring 75 due to the withdrawal of the second hook portion 49. By returning a part of the pins 74 to the supporting position, the tips 74b of a part of the pins 74 are disposed (aligned) along the surface 24b of the rear side column 24.

Here, as described above, the plurality of pins 74 are completely aligned in a honeycomb shape. Thus, the pins 74 return to the supporting position by the withdrawal of the second hooks 49, so that the tips 74b of the plurality of pins 74 are disposed (aligned) entirely along the surface 24b of the rear side column 24.

This prevents the exterior appearance from being impaired even when the receiver 46 is provided in the vehicle. That is, the opening/closing body structure of the motor vehicle can be applied to, for example, the side door 31 for opening/closing the rear opening 14 of a normal motor vehicle.

< front side door Structure >

As shown in fig. 1, the front side door structure 15 does not include only a cross member corresponding to the second cross member 38 of the rear side door structure 16, and the other structures are similar to the rear side door structure 16.

According to the front side door structure 15, a third cross member (cross member, lower cross member) 85 is provided in the side door (opening/closing body) 84. The front end portion 85a of the third cross member 85 is supported by the first door hinge 86 to the front pillar 22, and the rear end portion 85b of the third cross member 85 is supported by the receiver mechanism 88 to the center pillar 23.

The receiver mechanism 88 of the front side door structure 15 is configured similarly to the receiver mechanism 35 of the rear side door structure 16. That is, the hook of the receiver mechanism 88 is attached to the rear end portion 85b of the third cross member 85, and the receiver of the receiver mechanism 88 is attached to the vehicle body 11 (specifically, the center pillar 23).

The front portion of the side door 84 of the front side door structure 15 is supported by the front pillar 22 by a first door hinge 86 and a second door hinge (door hinge) 87 so that the side door 84 of the front side door structure 15 opens and closes the front opening 13. In a state where the side door 84 is closed, the rear portion of the side door 84 is supported by the center pillar 23 by the door lock device 89 and the receiver mechanism 88.

According to the front side door structure 15, the deformation of the vehicle body 11 (i.e., the center pillar 23) toward the vehicle cabin due to the impact load input to the vehicle 10 can be suitably suppressed, as in the rear side door structure 16.

In addition, according to the front side door structure 15, the exterior appearance of the vehicle is not affected in the same way as the rear side door structure 16.

In addition, according to the front side door structure 15, similarly to the rear side door structure 16, the receiver mechanism 88 can allow for a deviation that occurs when the side door 84 is mounted to the vehicle body 11 (i.e., the front pillar 22).

In addition, the front side door structure 15 can obtain the same effects as the rear side door structure 16.

< method for manufacturing opening/closing Structure of Motor vehicle >

Next, a method for manufacturing the rear door structure 16 will be described with reference to fig. 3 to 5 as a typical example of a method for manufacturing an opening/closing body structure of an automobile.

First, as shown in fig. 3 and 4, in the first step, the plurality of pins 74 are supported by the plate 72 in a honeycomb shape so as to be movable in the direction of entry of the hooks 45.

Specifically, for example, the shaft portion 78 of the support rod 73 is inserted through the through hole 77 from the screw portion 78a toward the plate back surface 72b. The support rod 73 is projected from the plate surface 72a side, and the head 79 of the support rod 73 is abutted against the plate back surface 72b.

Next, the spring 75 is fitted from the screw portion 78a to the shaft portion 78 protruding from the through hole 77 to the plate surface 72a side. Then, the screw portion 78a is screwed into the screw hole 74a of the base end portion of the pin 74, and the support rod 73 is coaxially attached to the pin 74. In this state, the spring 75 is interposed between the base end portion of the pin 74 and the plate surface 72a in a compressed state.

The pin 74 is biased in a direction away from the plate surface 72a by the biasing force of the spring 75, and the head 79 of the support lever 73 is locked to the plate back surface 72b. The head 79 is locked to the plate back surface 72b, so that the support rod 73 is attached to the plate 72, and the pin 74 is disposed at the support position.

Through the above steps, the other support rods 73 are attached to the plate 72, and the other plurality of pins 74 are arranged at the support positions. The plurality of pins 74 attached to the plate 72 are supported in the shape of a dense honeycomb by, for example, arranging the tips 74b on the same surface and contacting the adjacent pins 74.

The plurality of pins 74 are supported so as to be movable in the direction of entry of the second hook 49 (i.e., the axial direction of the support rod 73). This completes the first step of assembling the pin group 57 outside the housing 55.

Next, as shown in fig. 3 and 5, in the second step, the housing 55 of the receiver 46 is housed in the post interior 65 of the rear post 24 from the opening 24a of the rear post 24. By receiving the housing portion 55, the surface 24b of the rear post 24 contacts the flange portion 56 of the receptacle 46. In this state, bolts 67 are inserted into a pair of attachment holes 66 (see fig. 4) of the flange portion 56, and are screwed to the rear post 24. Thus, the flange portion 56 (i.e., the housing portion 55) is attached to the rear post 24 by the pair of bolts 67.

In the housing portion 55 attached to the rear pillar 24, the pin group 57 is accommodated in the interior 63 from an opening (i.e., the top portion 55 a) of the housing portion 55. The plate 72 of the accommodated pin group 57 is pressed into the inner surface 58a of the housing peripheral wall 58, whereby the plate 72 is fixed to the housing portion 55. In this state, the distal ends 74b of the plurality of pins 74, which are disposed opposite (in alignment with) the outside of the rear side column 24, are disposed along the surface 24b of the rear side column 24.

In this way, according to the method of manufacturing the opening/closing body structure of the vehicle, in the first step, the plurality of pins 74 are supported in the plate 72 so as to be movable in the direction of entry of the hooks (specifically, the second hooks 49) and so as to be honeycomb-shaped. Next, in the second step, the pin group 57 having the plurality of pins 74 and the like supported by the plate 72 is accommodated in the housing 55. The received plate 72 is pressed into the housing portion 55 to be fixed. Thus, the plurality of pins 74 (i.e., the pin group 57) can be simply accommodated in the housing portion 55, and the receiver 46 can be easily manufactured.

The technical scope of the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

For example, in the above embodiment, the front door structure and the rear door structure 16 are described as the opening/closing body structure of the vehicle, but the present invention is not limited thereto. As another example, the opening/closing body structure of the motor vehicle may be applied to a trunk, a shade, or the like. Even when the opening/closing body structure of the motor vehicle is applied to a trunk, a hood, or the like, the effect of appropriately dispersing an impact load caused by a collision to the trunk, the hood, or the like and suppressing deformation to the vehicle cabin of the vehicle body 11 can be obtained in the same manner as the front door structure, the rear door structure 16, or the like.

In the above embodiment, for example, the example in which the hook 45 is provided to the side door 31 on the rear side of the vehicle body and the receiver 46 is provided to the rear pillar 24 has been described, but the present invention is not limited thereto. As another example, for example, the receiver 46 may be provided in the side door 31, and the hook 45 may be provided in the rear pillar 24.

In the above embodiment, for example, the example of the impact load F1 input from the left side to the vehicle 10 due to the side collision has been described, but the impact load is not limited to the load due to the side collision or the like.

In addition, the components in the above-described embodiments may be appropriately replaced with well-known components within a range not departing from the gist of the present invention, and the above-described modifications may be appropriately combined.
