Electric vehicle rollover prevention device

Abstract

The invention discloses an electric vehicle rollover prevention device which is characterized by comprising a passive telescopic buffer mechanism, the passive telescopic buffer mechanism is connectedwith a hydraulic shock absorber in series, one end of the hydraulic shock absorber is connected with an axle of an electric vehicle, and the other end of the hydraulic shock absorber is connected withthe passive telescopic buffer mechanism; the passive telescopic buffer mechanism comprises a supporting plate, the supporting plate is connected with a hydraulic damper, a first air chamber is arranged on the other face of the supporting plate, and the end, deviating from the supporting plate, of the first air chamber is connected with a frame of the electric vehicle ; the shape of the first airchamber changes along with pressure; and the frame of the electric vehicle is further provided with a second air chamber, the first air chamber is communicated with the second air chamber, the secondair chamber is further communicated with a passive inflator, one end of the inflator is connected with the axle, and the other end of the inflator is connected with the frame. According to the scheme,the device has the beneficial effects that the structure is simple, the design is reasonable, the electric vehicle can be prevented from rolling over when running on a bumpy road surface, and the electric vehicle can also be prevented from rolling over when turning.

Description

technical field [0001] The invention relates to the safety field of electric vehicles, in particular to an anti-rollover device for electric vehicles. Background technique [0002] With the discovery of technology, there are more and more small and environmentally friendly electric vehicles. However, due to the narrow body of electric vehicles, once potholes appear on the road during driving, the body tilts at a larger angle and the deflection speed is also faster, which will form an inertia that continues to tilt, resulting in rollover. That is to say, an electric vehicle placed in a pothole at rest may not necessarily roll over, but a sudden drop on one side may easily cause rollover. And even when driving on a flat road, the speed will be faster due to the flat road. When turning, due to the centrifugal force, it is easy to roll outwards. Contents of the invention [0003] The present invention aims at the deficiencies in the prior art, and provides a simple structure...

Problems solved by technology

However, due to the narrow body of electric vehicles, once potholes appear on the road during driving, the body tilts at a larger angle and the deflection speed is faster, which will form an inertia that continues to tilt, resulting in rollover

That is to say, an electric vehicle placed in a pothole at rest may not necessarily roll over, but a sudden drop on one side may easily cause rollover

Moreover, even when driving on a flat road, the speed will be faster due to the smooth road surface. When turning, due to the centrifugal force, it is easy to roll outwards.
