Abstract
The invention relates to an automobile anti-collision device, in particular to a pneumatic automobile anti-collision device. The pneumatic automobile anti-collision device comprises a front bumper, a push rod, an air cylinder, a return-blocking air valve, a pneumatic safety valve, a linkage air valve assembly, an air compressor and a corresponding connecting pipeline. When a poking rod of the linkage air valve assembly is pushed forwards, compressed air in the air compressor enters a front pneumatic chamber of the air cylinder through a prior linkage air valve of the linage air valve assembly, and therefore the front bumper is tightly attached to the front portion of an automobile bumper. On dangerous circumstances, the poking rod is pushed backwards, the compressed air enters a rear pneumatic chamber of the air cylinder through a rear linkage air valve, the front bumper is made to move forwards quickly, and therefore impact force is converted to compression force for air in the rear pneumatic chamber so as to reduce or eliminate damage caused to an automobile, a driver and passengers by impact. Compared with the prior art, the pneumatic automobile anti-collision device has the advantages of being simple in structure, easy to manufacture and install, convenient to operate and control and good in anti-collision effect. When the pneumatic automobile anti-collision device is installed on the automobile, a good protection effect can be achieved, and therefore losses caused by traffic accidents can be avoided and reduced to the maximum.
