Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a stopper structure for a rear bumper in a vehicle.

(Prior Art) Examples of conventional rear bumper stopper structures include those shown in FIGS. 3 and 4.

A vehicle (the figure shows a van-type vehicle) 1 has a frame structure, and a frame 2 is covered with a rear panel 3 and a tail cloth 4, and a rear bumper 5 is provided on the rear side of the rear panel 3.
The left and right stays 7 of the stiffeners 6 of the rear bumper 5 are attached to the tail cross 4 through the rear panel 3, and stoppers 8 are attached to the left and right ends of the frame 2, respectively, so as to face the respective attachment points. There is. Note that 9 is the vehicle floor and 10 is the rear gate.

(Problems to be Solved by the Invention) However, in such a conventional rear bumper stopper structure, the stoppers 8 that face the left and right stays 7 of the rear bumper 5 are attached to the left and right ends of the frame 2. Because the structure was such that the rear bumper 5 had a structure of only
There was a problem that deformation of the rear panel 3 due to the above cannot be prevented to the minimum.

(Means for solving the problem) This invention was made by focusing on such conventional problems, and as a means to solve the problem, it is provided with a frame structure, and the rear member of the frame is made up of a rear panel, a tail cross, etc. In a vehicle that is covered with a rear bumper and further provided with a rear bumper on the rear side of the rear panel, a central portion of the rear member of the frame;
A through hole is formed in the rear panel and the tail cross between the center portion of the rear bumper and extends in the front-rear direction, a stopper is passed through the through hole, and the front end of the stopper is attached to the rear member to maintain a gap. The rear end of the stopper is opposed to the stiffener of the rear bumper with a gap therebetween, and a reinf having a hole communicating with the through hole is attached to the tail cross, and the reinf is attached to the reinf of the stopper. The purpose is to solve the above-mentioned problems by attaching it via bolts.

(Function) According to the above means, since the impact force on the rear bumper is received by the rear member of the frame via the stopper, excessive impact force is not applied to the rear panel.

(Example) This invention will be explained below based on the drawings.

FIG. 1 is a diagram showing an embodiment of this invention,
This corresponds to the - line sectional view in FIG. 3 above.
Moreover, since this example was implemented in the vehicle 1 described in the above-mentioned prior art, the same parts are denoted by the same reference numerals.

First, to explain the configuration, frame 2 of vehicle 1
The rear panel 3 and tail cross 4 between the center of the rear member 11 and the center of the rear bumper 5 are provided with through holes 12, 1 that penetrate in the front-rear direction.
3 is open. A stopper 14 is passed through the through holes 12 and 13, and the front end of the stopper 14 faces the rear member 11 with a gap A maintained, and the rear end of the stopper 14 faces the rear bumper 11.
is opposed to the stiffener 6 with a gap B maintained therebetween.

A reinf 15 having a hole (numerical omitted) communicating with the through hole 13 is attached to the tail cross 4. The stopper 14 is attached to the rainf 15.
is attached with bolts 16. Incidentally, the bolt hole 17 of the rainf 15 is formed in an elongated shape, and the bolt 16 can be adjusted by moving in the bolt hole 17 in the front and rear direction.

Next, the effect will be explained.

If a forward impact force is applied to the rear bumper 5 of the vehicle 1, that is, if the vehicle 1 has a slight collision with a following vehicle or if the vehicle 1 has a slight collision with a fixed object etc. when reversing, the impact input to the rear bumper 5 will be reduced. The force F is transmitted from the stiffener 6 to the tail cross 4 through the left and right stays 7, and is received by the left and right stoppers 8 (see FIG. 4).

At the same time, at the center of the rear bumper 5, the gap B between the rear end of the stopper 14 and the stiffener 6 of the rear bumper 5 becomes zero as the rear bumper 5 is deformed by the impact force F. continue,
A component force fo of the impact force F is transmitted to the stopper 14. Due to the force fo, the tail cross 4 and rear panel 3 move forward together with the stopper 14 via the rainf 15 until the gap A between the front end of the stopper 14 and the rear member 11 of the frame 2 becomes zero, and the gap A becomes zero. Then, tail cross 4
And the rear panel 3 stops moving, and the stopper 1
4 is received by the rear member 11 of the frame 2.

Therefore, the deformation (displacement) of the rear panel 3 can be managed by adjusting the gap A. For example, if the gap A is set so that the displacement of the rear panel 3 does not hinder the opening and closing of the rear gate 10, excessive impact will not be applied to the rear panel 3, and deformation of the rear panel 3 can be prevented to a minimum. At the same time, impact energy is absorbed by minimal deformation of the rear bumper 5, tail cross 4, and rear panel 3.

(Effects of the invention) The present invention provides a vehicle having a frame structure, a rear member of the frame covered with a rear panel, a tail cloth, etc., and a rear bumper provided on the rear side of the rear panel. A through hole is formed in the rear panel and the tail cross between the rear panel and the center portion of the rear bumper, and a stopper is passed through the through hole, and the front end of the stopper is inserted into the rear member into the gap. The rear ends of the stoppers are opposed to the stiffeners of the rear bumper with a gap therebetween, and a reinf having a hole communicating with the through hole is attached to the tail cross, and the reinf has a hole communicating with the through hole. Because the stopper is attached via a bolt, in the event of a minor collision with the vehicle, etc., the gap between the rear end of the stopper and the rear bumper becomes zero as the rear bumper deforms due to the impact force, and then The impact force is transmitted to the stopper,
The tail cross and rear panel move forward together with the stopper via the rainf until the gap between the front end of the stopper and the rear member becomes zero. When the gap becomes zero, the tail cross and rear panel stop moving, and the force from the stopper is transferred to the frame. It is received by the rear member, so that no severe impact is applied to the rear panel, and deformation of the rear panel can be minimized by adjusting the gap. Collision can be prevented by minimizing deformation of the rear bumper, tail cross, and rear panel. It has the effect of being able to absorb energy.
