Angle-adjustable air-spray anti-rollover device and method

Abstract

The invention discloses an angle-adjustable air-spray anti-rollover device and a method and belongs to the technical field of vehicle active safety. The device comprises a compressor, a left air sprayport, a right air spray port, a left universal ball joint, a right universal ball joint, a left vertical guide rail, a right vertical guide rail, a left high pressure air pump, a right high pressureair pump, a left control motor and a right control motor. According to the device, the air spray ports can achieve multi-angle air spray at different positions of the guide rails according to a rollover danger signal, anti-rollover torque is formed, the device can work under different modes according to the rollover danger degree, and the anti-rollover effect is achieved. The invention further discloses the adjustment method of the device. The device and method are suitable for vehicles of different types, the device is simple in structure, the air spray effect can be adjusted in real time when the rollover danger occurs, the danger of rollover of the vehicles is reduced, the safety of the vehicles can be improved, and the driving stability of the vehicles is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to an angle-adjustable air jet anti-rollover device and method. Background technique [0002] Car rollover is a serious traffic accident, which brings huge losses. Once a car rolls over, it will not only threaten the safety of the drivers and passengers in the car, but also cause serious secondary accidents. Rollover accidents often occur in a short period of time, and it is difficult to control only by the driver's operation. It is necessary for the anti-rollover device to intervene quickly and efficiently to achieve the anti-rollover effect. [0003] In order to solve the above anti-rollover problem, Shen Xiaohua from Suzhou City, Jiangsu Province invented a vehicle anti-rollover device and method (application number 201610889959.4), which includes a slider sensor switch control system and an anti-rollover system. , the anti-rollover system includes an upper anti...

[0003] In order to solve the above anti-rollover problem, Shen Xiaohua from Suzhou City, Jiangsu Province invented a vehicle anti-rollover device and method (application number 201610889959.4), which includes a slider sensor switch control system and an anti-rollover system. , the anti-rollover system includes an upper anti-rollover unit and a lower anti-rollover unit. This invention connects a gravity hammer through an electronic controller. When the vehicle is about to rollover, the weight of the higher side of the vehicle is increased by the movement of the gravity hammer so that The vehicle quickly restores its balance to prevent the vehicle from rolling over, but the gravity hammer increases the mass of the vehicle, and the movement of the gravity hammer takes a certain time, and the response speed is not fast enough

[0004] Jing Yajie of Chang'an University invented an emergency safety device for anti-rollover of automobiles (public number CN206623830U), which includes an electronic control unit, a vehicle motion state monitoring mechanism for real-time monitoring of vehicle motion state, and two Set of telescopic support mechanism, when the vehicle motion state monitoring mechanism detects that the vehicle rolls over, the electronic control unit controls the piston rod of the drive cylinder corresponding to the rollover direction to extend out, and the solid rubber ball of the universal wheel at the lower part of the tapered support cover touches the ground Full contact can prevent the vehicle from rolling over, but the supporting structure has a certain impact on the original structure of the car, and the structure is relatively complicated and not very practical

[0005] Gong Weidong of Jiangsu Jinmi Intelligent Technology Co., Ltd. invented a control method for vehicle anti-rollover system based on tension sensing (application number 201610953138.2). Springs and tension sensors are installed on both sides of the vehicle, and the deformation of the spring and the sensor The collected signal judges the rollover tendency of the car, so as to achieve the purpose of anti-rollover by adjusting the jet module. However, the jet direction and jet pressure of the jet module in this invention are fixed, and real-time adjustment cannot be achieved.
