Automobile rollover prevention device

Abstract

The invention discloses an automobile rollover prevention device comprising an automobile body. Brackets are mounted on the left side and the right side of the automobile body, racks are arranged in the brackets, the brackets are connected with the racks, and an air cylinder is arranged outside the racks and is electrically connected with the automobile body; and a jacking rod is mounted at the bottom of the air cylinder, a fixing block is mounted at the bottom of the jacking rod, second rotating rods are mounted on the left side and the right side of the fixing block correspondingly, and supporting rods are connected to the exteriors of the second rotating rods in a sleeving mode. According to the automobile rollover prevention device, through cooperation of the supporting rods, the fixing block and the jacking rod, under the effect of a buffering piece, the supporting rods and the fixing block are mutually connected and move along with rotating of the jacking rod, thus the stabilityof the fixing block is improved, and the service life of the fixing block is prolonged; and under the effect of idler wheels, the two sides of the automobile body can be supported through the idler wheels, the unfolding area of the automobile body is decreased, the safety of the automobile body is improved, and the automobile rollover prevention device is suitable for being used and popularized.

[0002] There are many kinds of existing automobile safety devices, such as installing a bumper on the car body to strengthen the reliability and sensitivity of the control system, and some distance measuring devices are installed on the car body to realize early warning. These safety devices are all from Different angles guarantee the safety of the car to a certain extent. In addition, if the car encounters a sharp turn or dodges during high-speed driving, the car will lose its balance due to the centrifugal force, which will seriously cause the car to roll over. When this type of accident occurs in a car, the usual way is to reduce the height of the car chassis, thereby lowering the center of gravity of the car body, or widening the width of the two sides of the car body, etc., but after reducing the height of the car chassis, the car is required to have a good The condition of the road surface will limit the driving range of the car, and widening the width of the two sides of the car will restrict the development of the car model, and will also reduce the flexibility of the car. In the prior art, for example, the invention patent application number is 98236213.7 It includes a telescopic rollover frame symmetrically arranged on both sides of the chassis of the car. The rollover frame is composed of a telescopic strut composed of at least two sleeves and a ground-touching rollover rod fixed at the front end of the telescopic strut. , an elastic member is placed in the cavity of the telescopic strut, and a return locking hole corresponding to the lock pin provided on the automobile is provided at one end of the ground-touching rollover bar. The elastic member is a spring, and the There are two telescopic support rods on one side and three on the other side. Although the invention has a simple structure, there are many deficiencies and defects. In the existing equipment, there are defects in the design of the telescopic rollover frame. The telescopic rollover frame can affect the vehicles on both sides, affecting the normal formation of the vehicle, and there are potential safety hazards. Once it scratches with the test vehicles on both sides, the consequences are unimaginable. The expansion area of ​​the telescopic rollover frame when it is used If it is too large, it will block the sight of the vehicles behind. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a vehicle anti-rollover device to overcome the defects in the prior art.
