When a collision occurs, the second rigid structure of the device deforms to absorb energy. The material of the second rigid structure is steel and has sufficient anti-collision ability to protect the batteries in the lower box body of the rear vehicle battery box.
[0003] However, the rear side beam structure of the lower box body of the battery box of the existing new energy vehicle battery box and the anti-collision structure in the device are all arranged together, which cannot quickly disperse the collision force and achieve a better effect of alleviating the collision force.

[0012] The utility model provides a right beam structure of the lower box of a battery box, which has the following beneficial effects:
[0013] 1. In this device, by setting a buffer frame, when it is impacted, it starts to disperse the pressure on the front and rear sides.

DETAILED DESCRIPTION
[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0020] refer to Figure 1-3The utility model provides a technical solution: a right beam structure of a lower box body of a battery box, comprising a lower box body 1 of the battery box, the front and rear sides of the lower box body 1 of the battery box are fixedly connected with connecting plates 2, the right sides of the two connecting plates 2 are respectively rotatably connected with movable plates 4, by setting the movable plates 4, when the buffer frame 5 is hit, the buffer frame 5 moves to the left, the intersection of the two movable plates 4 is jointly rotatably connected with a rotating shaft 3, by setting the rotating shaft 3, the rotation of the movable plate 4 is achieved, the other side of the movable plate 4 is rotatably connected with the buffer frame 5, the buffer frame 5 is fixedly connected with a rubber pad 6, by setting the rubber pad 6, it contacts with the collision object, and distributes the impact force to different structures respectively, quickly distributes the impact force, and reduces the impact on the lower box body 1 of the battery box, one side of the rubber pad 6 is fixedly connected with a second anti-pressure plate 8, and the right side of the lower box body 1 of the battery box is fixedly connected with a first anti-pressure plate 10.
[0021] Among them, the right side of the first pressure-resistant plate 10 is fixedly connected with a steel structure body 11. By setting the steel structure body 11, it has higher strength and reduces the deformation of the lower box body 1 of the battery box during impact. The side of the steel structure body 11 facing away from the first pressure-resistant plate 10 is fixedly connected with a fixed frame 12.
[0022] The inner wall of the fixing frame 12 is fixedly connected with a rubber pad 13 .
[0023] The second anti-compression plate 8 is filled with foam. By providing the second anti-compression plate 8 , the impact force can be absorbed and dispersed when a collision occurs. The front and rear sides of the second anti-compression plate 8 are fixedly connected to the buffer frame 5 .
[0024] The left side of the second anti-compression plate 8 is fixedly connected with a shock-absorbing plate 9. By providing the shock-absorbing plate 9, most vibrations can be alleviated.
[0025] The front and rear sides of the shock absorbing plate 9 are fixedly connected in the buffer frame 5 , and the front and rear sides of the rubber pad 6 are fixedly connected in the buffer frame 5 .
[0026] The working principle of the utility model is as follows: when the external impact force is applied to the right beam of the lower box body 1 of the battery box, it will first hit the rubber pad 6, and at the same time, the buffer frame 5 starts to move to the left under the action of the force, and a certain impact force will be relieved during the movement. When the impact force is large, the buffer frame 5 will be pushed to the left to the limit, shortening the distance between the connecting plate 2 and the buffer frame 5. At the same time, under the action of the second pressure-resistant plate 8, most of the impact force can be relieved. Due to the foam arranged in the second buffer plate, the impact force can be absorbed and dispersed when it is collided. At the same time, the impact force is greatly weakened by using the shock-absorbing plate 9. The steel structure body 11 has a strong hardness, which greatly reduces the deformation of the lower box body 1 of the battery box during the collision.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
