Double-air-cylinder spring-resetting-type automatic anti-stabbing safety device

Abstract

The invention discloses a double-air-cylinder spring-resetting-type automatic anti-stabbing safety device. A high-rigidity support structure is mounted and fixed to a vehicle body in front of tires, thus permanent-magnetic thorn-attracting magnet blocks at the lower end of the high-rigidity support structure can attract small steel thorn objects in front of the tires in the whole vehicle travelling and parking processes, and whether the steel thorn objects are attracted or not is detected through long powered-on infrared detectors on the two sides of the support structure, and after it is detected that the thorn objects exist, a computer of a system receives a signal and sends the signal to an air way control valve; and an air way at the end, connected with the air cylinder, of the valve is opened, compressed air enters to push a piston rod to stretch out, and an air cylinder rod pushes an electromagnet mechanism to downwards move along a support guiding groove through idler wheels; and meanwhile the movable electromagnet blocks generating magnetism after being powered-on is powered on, thus the electromagnet blocks originally without the magnetism take the effect withhigher magnetism than permanent magnets, and damage to a vehicle and passengers due to the fact that the tires of the vehicle are punctured is effectively prevented.

Description

technical field [0001] The invention discloses a double-cylinder spring return type automatic anti-stab safety device, which belongs to the technical field of vehicle safety. Background technique [0002] With the rapid development of China's automobile industry and the substantial increase in car ownership, the number of casualties and property losses caused by traffic accidents in my country has also increased significantly each year. The passive safety performance of automobiles has naturally received more and more attention from the majority of Chinese people. Manufacturers are also increasingly taking the safety of their products as the focus of publicity. More and more of the world's latest safety technology research results have been introduced into China, and more and more Chinese engineers and R&D personnel have begun to focus on vehicle The field of tire safety technology. In the existing vehicle tire safety technology, for the patent No. 200920025397.4, the cont...

Problems solved by technology

In the existing vehicle tire safety technology, for the patent No. 200920025397.4, the content of the invention is to hang the inventive device described in it in front of the tire, and hang a magnet on the car through two ropes. This method is simple in structure. The operation is convenient, but although this method can allow small pieces of iron and steel sharp objects such as iron nails to be absorbed by the magnet, because the rope is soft, if the vehicle is bumped or accelerated or decelerated, it is easy to make the magnet and the iron nails on it Hitting the vehicle parts such as tires is easy to cause damage to the vehicle parts, and the rope is easily cut off by the swing of the magnet for a long time, causing the vehicle tires to be punctured by the falling nail-containing magnet block

Most importantly, when the magnet attracts too much steel and other objects, if it cannot be found in time, it cannot be cleaned up in time. If it accumulates too much, it will fall back to the front of the tire due to insufficient magnet attraction during bumps, and the tire will be rolled over and cause secondary damage. puncture risk

[0003] Patent No. 201420091299.1 installs the stab-proof iron-absorbing device on the axle through the bracket. The magnet block on the invented device is installed on the bracket with a spring. The magnet block swings irregularly, causing the sharp objects attracted to the magnet to touch the tires and components, especially the elastic bumps aggravate the shaking of the magnet block, and it is easy to make the sharp iron objects attracted to it fall on the front of the tire. Secondary puncture damage from tire

Most importantly, when the magnet attracts too much steel and other objects, if it cannot be found in time, it cannot be cleaned up in time. If it accumulates too much, it will fall back to the front of the tire due to insufficient magnet attraction during bumps, and the tire will be rolled over and cause secondary damage. puncture risk
