Problems solved by technology
[0003] However, when a non-axial force is applied, that is, when the angle between the impact force and the axis of the shell is between 0-90°, the force on both sides is different, and it is on the side of the shell close to the impact force. Stress concentration makes the shell present a certain angle relative to the connecting part, which may easily cause the buffer card and the connecting part to be stuck, resulting in weakened buffering effect. Moreover, the device is a disposable device and cannot be reused

Embodiment Construction
[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0018] See Figure 1~2 In the embodiment of the present invention, an improved automobile cushioning device includes a housing 2 and a connecting portion 1. The head end of the connecting portion 1 is placed in the housing 2 and is restricted by a restricting tooth 6. The teeth 6 are clamped on the step at the head end of the connecting part 1 to prevent the connecting part 1 from slipping out of the housing 2. The housing 2 is a cap-sha...

The invention discloses an improved automobile buffering device. The improved automobile buffering device comprises a shell and a connecting part, wherein the head end of the connecting part is arranged in the shell and limited through limiting teeth, the limiting teeth are clamped on the step of the head end of the connecting part, the shell is of a bottle-cap-shaped structure of which one end is open, a buffering ball used for buffering impact is arranged between the shell and the end of the connecting part, and the buffering ball is made of rubber and is of a hollow structure. The improved automobile buffering device has the advantages that the buffering ball can achieve a buffering effect as long as the included angle formed between the external acting force and the axis direction of the shell is smaller than 90 degrees; in addition, the contact face of buffering cards and the step of the head end of the connecting part is an inclined face, the included angle formed between the inclined face and the shell ranges from 30 degrees to 45 degrees, the contact face is relatively smooth, therefore, higher smoothness is achieved when relative movement is generated between the buffering cards and the connecting part, and the buffering card jamming phenomenon caused by non-axial impact is especially reduced although energy consumption of the buffering cards is reduced as movement is smoother.
Description
Technical field [0001] The invention relates to the technical field of automobile machinery, in particular to an improved automobile buffer device. Background technique [0002] Chinese invention patent CN 206186951 U discloses an automobile buffer device. When an impact is received, the shell compresses the spring. During the extrusion process, it is blocked by the buffer card one by one to gradually reduce the impact force. Finally, when the spring is compressed to the end , The spring pad plays a buffering role. The buffer pad is made of special materials, has good compression resistance and elasticity, and can effectively relieve the discomfort of the driver and passengers after being impacted. [0003] However, when subjected to a non-axial force, that is, when the angle between the impact force and the axis of the shell is between 0-90°, the force on both sides is different, and the force on the side of the shell near the impact force is different. The stress concentration m...
