When entering the state of anti-theft and anti-theft, the motor drives the reduction gear to drive the lock cylinder 11 to shift and brake. The oil seal base pestle 13 and the power oil seal seat rod 15 reset and close the brake cylinder port 7 and the fuel tank port 8 under the action of a reset spring. At this time, the power oil supply is cut off, the wheels are braked, and the steel core transmission locks the guide The cover cannot move the car at this time. Embodiment 1 of the latch cover lock: Referring to FIG. 8, a lock bolt 46 is installed in the shaft hole 48 of the lock base 47. The left end of the steel core wire 24 is fixed to the lock bolt 46, and the other end passes through the flexible shaft jacket 25 and the brake. The oil circuit is connected to the lock cylinder 11 of the power oil circuit lock. The flexible shaft jacket 25 is mounted on the socket 43 and the inner diameter is fixed on the lock socket 47 via a nut 44. A return spring 45 is fitted between the lock bolt 46 and the socket 43 and is set on steel On the core wire 24. The lock base 47 is mounted on the trigger cover or the vehicle body via the screw 54. The steel core wire 24 can be directly connected to the lock core 11 of the car anti-theft device, or it can be connected to the joystick installed in the cab, corresponding to the lock bolt 46. A lock ring or a drill hole is drilled on the body or the trigger cover. The working process of this embodiment is as follows: The movement causes the steel core wire 24 to move to the right, and the lock bolt 46 is pulled out from the lock ring or the keyhole to open the trigger cover. On the contrary, the steel core wire 24 is under the action of the reset spring 45 Insert the lock ring or lock hole to lock the trigger cover. Embodiment 2 of the latch cover: Referring to FIG. 10, there is a shaft hole 55 in the lock seat 47, and the left end of the cable 52 passes through the cable sleeve 53 and is connected to the latch puller in the cab of the car, and the right end is connected with the bolt seat. 49 is fastened and connected with the cable cover hook through the cable sleeve 53. A return spring 45 is installed between the bolt seat 49 and the sleeve seat 50. A bolt groove 56 corresponding to the lock bolt 46 is opened on the bolt seat 49 A lock bolt 46, a steel core wire 24, and a shaft hole 8 are provided below the bolt seat 49, and the structure is the same as that of the first embodiment. The working principle of this embodiment is: When the steel core wire 24 is moved as described in the embodiment 1, the lock bolt 46 is inserted into or withdrawn from the bolt groove 56 on the bolt seat 49, so that the opening handle of the latch cover is locked or released.

When the invention works, the user first sets his own power-on password. After the password is set, the microprocessor automatically saves the password permanently, and the user can also change his own password at will. In use, the preset password can only be selected properly. To achieve the purpose of starting the car, otherwise it will automatically be in the function of anti-theft and anti-theft, it will also disconnect the brake oil circuit and the power oil circuit, leading to the lock of the lock. The first three digits of the power-on password switch the central door lock. The other 2-5 digits are anti-theft functions, and any 6 or more digits are anti-theft functions. The anti-robbery function is: When the car robber drives the car out for 1-3 minutes (can be set ), The microprocessor controls the central door lock, the power oil circuit and brake oil circuit locks are closed, the power is off, the wheels are braked, and the cover is locked, and an alarm sounds. Only after the correct power-on password is selected, Cancel the alarm function.
