[0002] Shock absorbers are used to suppress the shock caused by the rebound of the spring after absorbing shock and the impact from the road. They are widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the car. At present, the shock absorbers used in automobiles are basically hydraulic shock absorbers. When the vehicle is driving on a bumpy road, the piston rod of the hydraulic shock absorber continuously retracts and retracts in the cylinder body, and the shock-absorbing oil in the cylinder body continuously flows up and down through the valve plate in the valve body to buffer the impact force and reduce the degree of bumpiness.

[0003] Existing hydraulic shock absorbers can often adjust the damping force by changing the cross-sectional area or pore size of the oil channel. However, this adjustment method has insufficient controllability, is complicated to operate, and is inconvenient to adjust.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Embodiment 1, as Figure 1-Figure 3 As shown, the electronically controlled variable damping shock absorber is composed of a hydraulic cylinder and a shock absorbing spring to form a shock absorber body. The shock absorber is installed at the wheel to start the shock absorbing effect during the vehicle driving process. When the softness and hardness of the shock absorber need to be adjusted, the driver can remotely adjust the solenoid valve 7 through the control unit 10 in the cab, and use the control unit 10 and the power distribution unit 9 to issue a control instruction. During the control instruction issuance stage, the circuit controller of the vehicle will generate a control instruction and send it to the solenoid valve 7 to realize power supply to the solenoid valve 7 through the power distribution unit 9. The device uses electronic control to achieve remote adjustment, and the solenoid valve 7 of the shock absorber is connected to the power distribution unit 9 through a wire 8. The user can use the control unit 10 in the car to remotely adjust the softness and hardness of the shock absorber without manual adjustment. When the solenoid valve 7 receives the control instruction, it will control the hydraulic oil at the hydraulic oil tank 20 to flow in the cylinder barrel of the hydraulic cylinder 12. Since the opening degree of the valve can be precisely controlled, the piston rod 13 of the hydraulic cylinder 12 will also drive the piston head 19 to make corresponding adjustments, thereby achieving the effect of adjusting the vibration reduction.

[0022] Embodiment 2, as Figure 1-Figure 3 As shown, an electrically controlled variable damping shock absorber, in which the damping coefficient of the shock absorber can be changed by adjusting the control current of the solenoid valve 7. By changing the current size of the hydraulic oil environment inside the hydraulic cylinder 12, the electromagnetic coil 18 on the outer wall of the piston rod 13 can be used to change the circulation speed and damping coefficient of the hydraulic pressure inside the shock absorber, thereby realizing the softness and hardness adjustment of the shock absorber.

[0023] How it works

[0024] It should be noted that the utility model is an electrically controlled variable damping shock absorber. When in use, the shock absorber is installed at the wheel to activate the shock absorbing effect during the vehicle's driving process. When the softness or hardness adjustment of the shock absorber is required, the driver can remotely adjust the solenoid valve 7 through the control unit 10 in the cab, and use the control unit 10 and the power distribution unit 9 to issue a control instruction. During the control instruction issuance stage, the vehicle's circuit controller will generate a control instruction and send it to the solenoid valve 7 to realize power supply to the solenoid valve 7 through the power distribution unit 9. The device uses electric control to realize remote adjustment, and the solenoid valve 7 of the shock absorber is connected to the power distribution unit 9 through a wire 8. The user uses the control unit 10 in the vehicle to remotely adjust the solenoid valve 7. The hardness and softness of the shock absorber can be debugged at a long distance without manual adjustment. When the solenoid valve 7 receives the control command, it will control the hydraulic oil in the hydraulic oil tank 20 to flow in the cylinder of the hydraulic cylinder 12. Since the opening degree of the valve can be precisely controlled, the damping coefficient of the shock absorber can be changed by adjusting the control current of the solenoid valve 7. By changing the current of the hydraulic oil environment inside the hydraulic cylinder 12, the electromagnetic coil 18 on the outer wall of the piston rod 13 can be used to change the circulation speed and damping coefficient of the hydraulic pressure inside the shock absorber, thereby realizing the hardness and softness adjustment of the shock absorber. The piston rod 13 of the hydraulic cylinder 12 will also drive the piston head 19 to make corresponding adjustments, thereby achieving the effect of adjusting the vibration reduction.
