Embodiment 1

[0020] like figure 1 , image 3 As shown, the automobile collision buffer device of the present invention can design the cross-sectional area ratio of the buffer cylinder 4 and the combined oil cylinder 1 according to the weight of the vehicle body itself and the collision strength. When the cross-sectional area of ​​the buffer cylinder 4 is small, the shock absorber 6 is not connected. In buffer cylinder 4.

[0021] The automobile collision buffer device of the present invention includes a hydraulic oil pipeline 3 connecting the combined oil cylinder 1 and the buffer oil cylinder 4. There are three combined oil cylinders 1, and the cross-sectional areas increase sequentially from left to right, with the leftmost oil cylinder being the first oil cylinder. That is, A cylinder, A cylinder is provided with a piston 2, and the previous cylinder is the piston of the next cylinder, that is, the A cylinder is the piston of the B cylinder, and the B cylinder is the piston of the C cy...

Embodiment 2

[0026] like figure 2 , image 3 As shown, the automobile collision buffer device of the present invention includes a hydraulic oil pipeline 3 connecting the combined oil cylinder 1 and the buffer oil cylinder 4. There are three combined oil cylinders 1, and the cross-sectional areas increase sequentially from left to right, with the leftmost oil cylinder being the first One oil cylinder, that is, A oil cylinder, A oil cylinder is provided with a piston 2, and the previous oil cylinder is the piston of the next oil cylinder, that is, the A oil cylinder is the piston of the B oil cylinder, and the B oil cylinder is the piston of the C oil cylinder. A pressure relief valve 5, a control valve 10 is provided on the hydraulic main pipe 9 leading to the brake system on the wall of the buffer cylinder 4, and a buffer cylinder piston 7 connected to the shock absorber 6 is also provided on the buffer cylinder 4, and a rotary valve is provided on the buffer cylinder piston 7. spring 8....

Abstract

The invention relates to a buffer device for collision of an automobile, in particular to an automotive passive safety device, wherein the front part and the rear part of a passenger compartment have the functions of buffering and absorbing energy. The buffer device comprises a plurality of combined oil cylinders, a buffer oil cylinder and hydraulic oil pipelines, wherein the leftmost oil cylinder is used as the first oil cylinder, a piston is arranged on the first oil cylinder, and the previous oil cylinder is used as a piston of the latter oil cylinder; the hydraulic oil pipelines are used for communicating the buffer oil cylinder and all combined oil cylinders; and a pressure release valve is arranged on the wall of the buffer oil cylinder, a control valve is arranged on a hydraulic main pipe arranged on the wall of the buffer oil cylinder and leading to a brake system, a buffer oil cylinder piston is further arranged on the buffer oil cylinder, and a rotating spring is arranged at one end of the buffer oil cylinder piston. When the collision of an automobile happens slightly, moderately or seriously, the buffer device can play a buffer role, and the brake system of the automobile is activated, so that large impact force capable of causing damage to human bodies is not generated instantly, and the safety of a driver and passengers inside the automobile is protected to the largest extent; and the buffer device is simple and reliable in structure.

Description

technical field [0001] The invention relates to an automobile collision buffer device, in particular to an automobile passive safety device which buffers and absorbs energy at the front and rear of the passenger compartment. Background technique [0002] In the collision accidents of automobiles, the front and rear collisions account for the vast majority. Therefore, it is of great significance to study the collision safety of the front and rear of automobiles. When a slight collision occurs, most of the existing automobiles are rigidly connected between the anti-collision steel beam and the body girder, which is easy to generate a large impact force and cause injury to the driver and passengers; in the event of a severe collision, the existing When the car is collapsing and absorbing energy, the impact force fluctuates greatly, and it is very easy to produce a large impact force that will cause serious damage to the human body. [0003] Based on this, the present invention...
