The lock system supplies power to ensure its normal battery life. The vehicle-mounted power storage device is connected to the vehicle-mounted control unit. When the battery management system of the vehicle-mounted control unit detects that the power supply of the vehicle-mounted power storage device that supplies power to it is disconnected, the control actuator locks the accelerator. Pedal 21.

The specific working process of the hydraulic oil circuit of the present invention is described in conjunction with the accompanying drawings:

In the state of FIG. 4 , at this time, the vehicle-mounted control unit 14 judges that there are people in the vehicle and the vehicle is running. When the pressure drops to a certain level, the pressure relay 12 sends a signal to start the oil pump 1, and the oil is sucked from the oil tank 10 to supply pressure oil to the system. The left position is connected to the circuit, and there is no control pressure at the control port of the second hydraulic control check valve 7, and its effect is equivalent to that of a common check valve. There is control pressure oil at the control port of the first hydraulic control check valve 4, and when the control pressure is greater than the resultant force of the pressure below the hydraulic control check valve and the spring force, the first hydraulic control check valve 4 is connected up and down, and the pressure oil passes through The throttle valve 2 and the second hydraulic control check valve 7 enter the rodless chamber of the double-acting hydraulic cylinder 6, the piston rod 5 slowly moves to the right, and the pressure oil finally flows back to the oil tank 10 through the first hydraulic control check valve 4 ; The outlet of the oil pump 1 is connected to the pilot proportional relief valve 9, which can adjust the input current of the proportional relief valve to adjust the working pressure of the hydraulic system, thereby changing the thrust of the piston rod 5.

In the state shown in Figure 5, the right position of the three-position four-way electromagnetic reversing valve 3 is connected to the circuit. At this time, the first hydraulic control check valve 4 is equivalent to an ordinary check valve, and the second hydraulic control check valve 7 is connected up and down. Through, the pressure oil enters the rod cavity of the hydraulic cylinder, and the piston rod 5 slowly moves to the left. The reciprocating motion of the piston rod 5 can be realized by periodically switching the positions of the three-position four-way electromagnetic reversing valve 3 .

In the state shown in Figure 6, the middle position of the three-position four-way electromagnetic reversing valve 3 is connected to the circuit, and the first hydraulic control check valve 4 and the second hydraulic control check valve 7 form a two-way hydraulic lock. Both the hydraulic control check valve 4 and the second hydraulic control check valve 7 are equivalent to ordinary check valves. The piston rod 5 of the hydraulic cylinder is locked in the hydraulic cylinder and cannot be moved by external force, thereby limiting the throttle action and realizing remote control. Lockout and anti-theft functions. And when the oil pump 1 is not working, the piston rod 5 can also be locked reliably for a long time.

In the state shown in Figure 7, the middle position of the three-position three-way solenoid valve 8 and the left position of the three-position four-way solenoid valve are connected to the circuit. 1 and the accumulator 11 supply oil to the hydraulic cylinder at the same time, so that the piston rod 5 moves quickly to prevent the user from continuing to step on the accelerator.

In the state shown in Fig. 8, the left position of the three-position three-way electromagnetic reversing valve 8 is connected to the oil circuit, and the oil pump 1 starts to work to supply oil to the accumulator 11, so that the accumulator 11 stores energy. When the pressure of the accumulator 11 rises to the set pressure, the pressure switch 12 sends a signal to stop the oil pump 1 .

The hydraulic system of the device can be combined with the existing anti-lock braking (ABS) system on the car, which reduces the cost of modification and is easy to implement. There are oil pump 1, accumulator 11, and pressure relay 12 in the anti-lock hydraulic system.
