Description

The present invention relates to a vehicle opening / closing body structure.

A structure is known in which a rear door that covers the rear door opening of the vehicle body so as to be openable and closable, and a support pillar that is connected to the vehicle body at one end and the other end is connected to the rear door. In such a structure, a ball joint provided on the rear door and a socket provided on the other end of the support column and oscillatingly accommodating the ball joint to connect the other end of the support column and the rear door. And further prepare.

A gap is required for manufacturing between the ball joint and the socket. However, the vibration of the vehicle while the vehicle is running may cause the ball joint and the socket to repeatedly come into contact with each other to generate noise. The grease injected between the ball joint and the socket suppresses the noise if the time elapsed after the vehicle is manufactured is short. However, due to the outflow and deterioration of grease over time, the ball joint and the socket may repeatedly come into contact with each other due to vibration during the running of the vehicle to generate noise.

Therefore, Patent Document 1 discloses a structure in which an annular cushion member is attached to a ball joint base that supports the ball joint at the rear door. In the structure of Patent Document 1, when the rear door covers the rear door opening of the vehicle body while the vehicle is running, the cushion member attached to the base of the ball joint abuts on the opening end of the socket to cause the ball. Noise caused by repeated contact between the joint and the socket is reduced.

By the way, in the structure as described in Patent Document 1, when assembling the socket to the ball joint at the time of manufacturing the vehicle, it is necessary to assemble the socket to the ball joint while compressing the cushion member attached to the base of the ball joint. A very large load is required to compress the cushion member, which may deteriorate the workability of assembling the socket to the ball joint.

Therefore, the present invention provides a vehicle opening / closing body structure that can prevent deterioration of workability of assembling the socket to the ball joint while reducing noise caused by repeated contact between the ball joint and the socket while the vehicle is running. The purpose is.

The present invention includes an opening / closing body that freely opens and closes an opening of a vehicle body, a support pillar having one end connected to the vehicle body and the other end connected to the opening / closing body, a ball joint provided in the opening / closing body, and a support pillar. A socket is provided at the other end to connect the other end of the support column and the opening / closing body by accommodating the ball joint so as to be swingable, and the opening / closing body is provided at the support column and covers the opening of the vehicle body. A vehicle equipped with an elastic body that sometimes applies a force in the direction of pulling the socket away from the ball joint and does not apply a force in the direction of pulling the socket away from the ball joint when the opening / closing body does not cover the opening of the vehicle body. It is an opening / closing body structure.

According to this configuration, an opening / closing body that covers the opening of the vehicle body so as to be openable / closable, a support pillar having one end connected to the vehicle body and the other end connected to the opening / closing body, and a ball joint provided in the opening / closing body are supported. In a vehicle opening / closing structure provided at the other end of a pillar and having a socket for connecting the other end of the support pillar and the opening / closing body by accommodating the ball joint so as to be swingable, the opening of the vehicle body is opened / closed. When the body is covered, an elastic body provided on the support column applies a force in the direction of pulling the socket away from the ball joint, and the force causes the ball joint and the socket to repeatedly contact each other while the vehicle is running. Can reduce the noise caused by. On the other hand, when the opening / closing body does not cover the opening of the vehicle body, the elastic body does not apply a force in the direction of pulling the socket away from the ball joint. By assembling, the elastic body does not get in the way, and deterioration of workability of assembling the socket to the ball joint can be prevented.

In this case, the elastic body is provided at the socket base that supports the socket at the other end of the support column, and is a ball joint that supports the ball joint with the opening / closing body when the opening / closing body covers the opening of the vehicle body. By contacting either the base or the opening / closing body, a force is applied in the direction of pulling the socket away from the ball joint, and when the opening / closing body does not cover the opening of the vehicle body, the ball joint, the ball joint base and the opening / closing body are separated from each other. Therefore, it is preferable not to apply a force in the direction of pulling the socket away from the ball joint.

According to this configuration, the elastic body is provided at the socket base that supports the socket at the other end of the support column, and the ball joint and the opening / closing body support the ball joint when the opening / closing body covers the opening of the vehicle body. By contacting either the ball joint base or the opening / closing body, a force is applied in the direction of pulling the socket away from the ball joint, and when the opening / closing body does not cover the opening of the vehicle body, the ball joint, the ball joint base and the opening / closing body are opened and closed. By separating from the body, no force is applied in the direction of pulling the socket away from the ball joint, so the simple structure can reduce the noise caused by repeated contact between the ball joint and the socket while the vehicle is running, and is an elastic body. This can prevent deterioration of workability of assembling the socket to the ball joint.

In this case, the elastic body preferably has an annular shape surrounding the periphery of the socket base.

According to this configuration, since the elastic body has an annular shape surrounding the periphery of the socket base, it is not necessary to strictly determine the direction of the elastic body when the elastic body is provided on the socket base, and the production is easy. ..

In this case, the support column does not have to apply either a tensile force or a compressive force between the vehicle body and the opening / closing body when the opening / closing body covers the opening of the vehicle body.

According to this configuration, the support column does not apply any tensile force or compressive force between the vehicle body and the opening / closing body when the opening / closing body covers the opening of the vehicle body, and the support pillar is a ball joint during the running of the vehicle. Since noise is likely to be generated due to repeated contact between the socket and the socket, the above-mentioned vehicle opening / closing structure of the present invention is effective.

According to the vehicle opening / closing body structure of the present invention, it is possible to prevent deterioration of workability of assembling the socket to the ball joint while reducing noise caused by repeated contact between the ball joint and the socket while the vehicle is running.

The support column 30 has a substantially cylindrical shape. The support column 30 has a nested structure in which circular tubes having different diameters are combined with each other, and is expandable and contractible in the telescopic portion 33. The support pillar 30 only expands and contracts according to the opening / closing operation of the opening / closing body 20, and when the opening / closing body 20 covers the opening 11 of the vehicle body 10, a tensile force is applied between the vehicle body 10 and the opening / closing body 20. And neither compressive force is applied.

The vehicle opening / closing body structure 1 includes a ball joint 40 provided in the opening / closing body 20. Further, the vehicle opening / closing body structure 1 is provided at the other end 32 of the support pillar 30, and a socket for connecting the other end 32 of the support pillar 30 and the opening / closing body 20 by accommodating the ball joint 40 so as to be swingable. 50 is provided. The ball joint 40 is supported by the opening / closing body 20 by the ball joint base 41. Specifically, the ball joint base 41 is a bracket attached to the opening / closing body 20. The socket 50 is supported by a columnar socket base 51 at the other end 32 of the support column 30.

As shown in FIGS. 1, 2, 3 (A) and 3 (B), the vehicle opening / closing body structure 1 includes an elastic body 100 provided on the support column 30. The elastic body 100 is provided on the socket base 51 that supports the socket 50 at the other end 32 of the support column 30. The elastic body 100 is made of synthetic rubber. As shown in FIGS. 3 (A) and 3 (B), the elastic body 100 has an annular shape including a mounting hole 101 surrounding the periphery of the socket base 51. As shown in FIG. 3B, the elastic body 100 has a ball joint 40 and a tapered portion 102 that follows the shape of the ball joint base 41 on the side of the socket 50. Further, the elastic body 100 has a groove 103 for removing water on the side of the other end 32 of the support column 30.

Hereinafter, the operation of the vehicle opening / closing body structure 1 of the present embodiment will be described. As shown in FIG. 2, when the opening / closing body 20 does not cover the opening 11 of the vehicle body 10, the elastic body 100 does not apply a force in the direction of pulling the socket 50 away from the ball joint 40. When the opening / closing body 20 does not cover the opening 11 of the vehicle body 10, the elastic body 100 moves away from the ball joint 40, the ball joint base 41, and the opening / closing body 20 in the direction of pulling the socket 50 away from the ball joint 40. Do not apply force.

On the other hand, as shown in FIG. 4, when the opening / closing body 20 covers the opening 11 of the vehicle body 10, the elastic body 100 applies a force F in the direction of pulling the socket 50 away from the ball joint 40. When the opening / closing body 20 covers the opening 11 of the vehicle body 10, the elastic body 100 comes into contact with any of the ball joint 40, the ball joint base 41, and the opening / closing body 20 to move the socket 50 from the ball joint 40. A force F in the pulling direction is applied. That is, when the elastic body 100 comes into contact with any of the ball joint 40, the ball joint base 41, and the opening / closing body 20, a reaction force that presses the end of the socket 50 against the ball joint 40 is generated.

In the present embodiment, when the opening / closing body 20 covers the opening 11 of the vehicle body 10, the elastic body 100 comes into contact with the ball joint base 41, thereby pulling the socket 50 away from the ball joint 40. Add. Even if the elastic body 100 abuts on the ball joint 40 and applies a force F in the direction of pulling the socket 50 away from the ball joint 40 when the opening / closing body 20 covers the opening 11 of the vehicle body 10. Often, a force F in the direction of pulling the socket 50 away from the ball joint 40 may be applied by contacting the opening / closing body 20.

According to the present embodiment, the opening / closing body 20 that covers the opening 11 of the vehicle body 10 so as to be openable / closable, the support pillar 30 having one end 31 connected to the vehicle body 10 and the other end 32 connected to the opening / closing body 20, and the opening / closing body. A socket provided at the ball joint 40 provided in the support column 20 and the other end 32 of the support column 30 and connecting the other end 32 of the support column 30 and the opening / closing body 20 by accommodating the ball joint 40 so as to be swingable. In the vehicle opening / closing body structure 1 provided with the 50, when the opening / closing body 20 covers the opening 11 of the vehicle body 10, the direction in which the socket 50 is separated from the ball joint 40 by the elastic body 100 provided on the support pillar 30. Since the force F is applied to the force F, it is possible to reduce the noise caused by the repeated contact between the ball joint 40 and the socket 50 while the vehicle is running. On the other hand, when the opening / closing body 20 does not cover the opening 11 of the vehicle body 10, the opening / closing body 20 covers the opening 11 because the elastic body 100 does not apply a force F in the direction of pulling the socket 50 away from the ball joint 40. By assembling the socket 50 to the ball joint 40 in a state where the socket 50 is not installed, the elastic body 100 does not get in the way, and deterioration of workability of assembling the socket 50 to the ball joint 40 can be prevented.

That is, even in a structure in which a cushion member is attached to a ball joint base that supports the ball joint at the rear door as in the structure described in Patent Document 1, noise due to repeated contact between the ball joint and the socket is reduced. It is possible. However, in such a structure, when assembling the socket to the ball joint at the time of manufacturing the vehicle, it is necessary to assemble the socket to the ball joint while compressing the cushion member attached to the base of the ball joint. A very large load is required to compress the cushion member, which may deteriorate the workability of assembling the socket to the ball joint.

However, according to the present embodiment, when the support pillar 30 is assembled to the vehicle body 10 while the socket is assembled to the ball joint, the opening / closing body 20 is in an open state, and the elastic body 100 provided on the support pillar 30 is the ball joint 40. Since the elastic body 100 is separated from the ball joint base 41 and the opening / closing body 20, the support column 30 can be assembled to the vehicle body 10 while assembling the socket 50 to the ball joint 40 without the elastic body 100 coming into contact with the ball joint base 41 or the like. it can.

Further, according to the present embodiment, when the elastic body 100 is provided at the socket base 51 that supports the socket 50 at the other end 32 of the support column 30, and the opening / closing body 20 covers the opening 11 of the vehicle body 10. , The ball joint 40, the ball joint base 41 that supports the ball joint 40 by the opening / closing body 20, and the opening / closing body 20 are brought into contact with each other, thereby applying a force F in the direction of pulling the socket 50 away from the ball joint 40, and the vehicle body 10 When the opening / closing body 20 does not cover the opening 11 of the above, the force F in the direction of pulling the socket 50 away from the ball joint 40 is not applied by separating the opening / closing body 20 from the ball joint 40, the ball joint base 41, and the opening / closing body 20. The simple structure can reduce noise caused by repeated contact between the ball joint 40 and the socket 50 while the vehicle is running, and the elastic body 100 can prevent deterioration of workability of assembling the socket 50 to the ball joint 40.

Further, according to the present embodiment, since the elastic body 100 has an annular shape surrounding the periphery of the socket base 51, it is necessary to strictly determine the direction of the elastic body 100 when the elastic body 100 is provided on the socket base 51. It is easy to manufacture.

Further, according to the present embodiment, when the opening / closing body 20 covers the opening 11 of the vehicle body 10, the support pillar 30 applies both a tensile force and a compressive force between the vehicle body 10 and the opening / closing body 20. However, since noise is likely to be generated due to repeated contact between the ball joint 40 and the socket 50 while the vehicle is running, the vehicle opening / closing body structure 1 of the present invention is effective.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and is implemented in various forms. For example, the vehicle opening / closing body structure 1 of the present embodiment is also applied in a mode in which the upper end portion thereof is pivotally supported by the vehicle body so that the opening / closing body 20 can rotate around a rotation axis parallel to the horizontal direction. It is possible. Further, the support pillars 30 may be arranged at any position between the vehicle body 10 and the opening / closing body 20, and the quantity thereof can be changed as appropriate. Further, the opening / closing body 20 may be a side door as well as a rear door. Further, the opening / closing body 20 does not necessarily have to cover the entire opening 11 of the vehicle body 10, and may, for example, cover a part of the loading platform of a freight vehicle such as a truck so as to be openable / closable.
