Embodiment 1

[0022] Such as figure 1 As shown, an anti-rollover system for an electric vehicle includes an electric vehicle battery pack 1 , a screw guide rail 2 , a stepping motor 3 , a PLC controller, and a pressure sensor 4 . The two sides of the bottom of the electric vehicle battery pack 1 are respectively fixed on the two sliders 203 of the screw guide rail 2, the two ends of the screw guide rail 2 are the first support base 201 and the second support base 202, and the stepping motor is fixed on the second support base 202. On the second support base 202, the pressure sensor 4 is fixed below the first support base 201, the data output end of the pressure sensor 4 is connected with the data input end of the PLC controller, the data output end of the PLC is connected with the stepping motor 3, and the PLC controller According to the data collected by the pressure sensor 4, the stepper motor 3 is controlled to rotate forward or reverse to drive the electric vehicle battery pack 1 on the...

Embodiment 2

[0028] Such as Figure 6 As shown, on the basis of Embodiment 1, in order to prevent the electric vehicle battery pack 1 moving at high speed and the body of the electric vehicle from violently colliding under extreme conditions, the first supporting base 201 and the second supporting base 202 can also be respectively Two baffles 5 are added on the side close to the battery pack 1 of the electric vehicle to protect the battery pack 1 of the electric vehicle. In order to increase the protection effect, a layer of elastic material 6 with a thickness of 2-12 mm can be covered on the baffle 5 for buffering , As a preference, use a rubber gasket with a thickness of 8mm. In addition, the stroke of the slider 203 can also be limited on the PCL controller to prevent the electric vehicle battery pack 1 from colliding with the electric vehicle body.

Abstract

An anti-rollover system of an electric vehicle comprises an electric vehicle battery pack, a lead screw guide rail, a stepper motor, a PLC and a pressure sensor. The electric vehicle battery pack is fixed to two sliding blocks of the lead screw guide rail. The two ends of the lead screw guide rail are provided with a first supporting seat and a second supporting seat. The stepper motor is fixed tothe second supporting seat. The pressure sensor is fixed to the lower portion of the first supporting seat. The data output end of the pressure sensor is connected with the data input end of the PLC.The data output end of the PLC is connected with the stepper motor. The PLC controls the stepper motor to rotate according to data collected by the pressure sensor so as to drive the electric vehiclebattery pack on the sliding blocks to move left and right. According to the provided anti-rollover system of an electric vehicle, the electric vehicle battery pack is utilized to adjust the gravity center of the electric vehicle, torsional moment of a part of centrifugal force is offset through gravity center shifting, and thus the rollover probability when the electric vehicle turns is greatly decreased.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to an anti-rollover system of the electric vehicle. Background technique [0002] When the car is running, emergency avoidance or turning speed is too fast, it is easy to cause a tipping accident due to excessive centrifugal force, causing serious losses. At present, some vehicle center of gravity adjustment systems prevent rollover by adjusting the center of gravity of the vehicle when the vehicle is turning. Patent CN200810232901 discloses a vehicle anti-rollover system, which resists part of the centrifugal moment by lowering the center of gravity of the vehicle when turning. Patent CN200910143765 discloses a car with an anti-rollover system and the anti-rollover system. When the vehicle is turning, the center of gravity is offset by tilting the car left / right to offset a part of the centrifugal force torsion moment. The above two center of gravity adjustment systems have complex structur...
