[0027] Such as Figures 1 to 5As shown in the figure, an anti-theft device for an electric vehicle motor includes a protection box 1. The front side wall of the protection box 1 is recessed relative to the left and right side walls. On the top surface of the front side wall of the protection box 1, an installation box 2 and an induction box 3 are fixedly installed. The induction box 3 is fixedly installed on the back surface of the installation box 2. A plurality of elastic extrusion structures 4 are arranged through the front surface of the installation box 2, and the number of the elastic extrusion structures 4 is several and evenly distributed. A touch pressure induction component is arranged on the front surface of the induction box 3. A clamping component 9 is arranged through the surface of the induction box 3. The touch pressure induction component includes a pressure sensor 6. The pressure sensor 6 and the clamping component 9 are respectively arranged corresponding to different elastic extrusion structures 4 before and after. On the top surface of the back side wall of the protection box 1, a top plate 10 is hinged. A lifting door 11 is slidably installed on the front surface of the top plate 10. The bottom surface of the lifting door 11 is attached to the top surface of the installation box 2. The clamping component 9 is slidably connected to the back surface of the lifting door 11. A lock body 18 that is engaged with the side wall of the protection box 1 is arranged on the surface of the lifting door 11. An electric vehicle motor body 17 is fixedly installed inside the protection box 1.

[0028] More specifically, by arranging a plurality of elastic extrusion structures 4 on the front surface of the installation box 2, and only one elastic extrusion structure 4 will push the clamping component 9 backward during the backward movement, so that the clamping component 9 slides away from the surface of the lifting door 11. Then, use the key to open the lock body 18, and then the lifting door 11 can be slid upward to open the lifting door 11 and the top plate 10, which is convenient for the maintenance of the electric vehicle motor body 17 fixedly placed in the protection box 1. During the backward movement of the remaining plurality of elastic extrusion structures 4, the surface of the pressure sensor 6 will be extruded. The pressure sensing signal generated by the pressure sensor 6 is processed by the touch pressure induction component and then transmitted to the processor of the electric vehicle. After being processed by the processor, an alarm is triggered, so that the vehicle owner can be informed in time.

[0029] The elastic extrusion structure 4 includes a limit sliding groove 401. The limit sliding groove 401 is opened inside the installation box 2. A limit sliding block 402 is slidably installed on the inner wall surface of the limit sliding groove 401. A key head 403 is fixedly installed on the front surface of the limit sliding block 402. The key head 403 protrudes from the front surface of the installation box 2 and is slidably arranged. A telescopic column 404 is fixedly installed on the back surface of the limit sliding block 402. The telescopic column 404 penetrates through the back surface of the installation box 2 and is slidably arranged. A spring 405 is sleeved on the surface of the telescopic column 404. The spring 405 is fixedly installed between the back surface of the limit sliding block 402 and the back inner wall of the limit sliding groove 401.

[0030] Specifically, pressing the button head 403 drives the limit slider 402 and the telescopic column 404 to move backward synchronously, so that the spring 405 is compressed, and the telescopic column 404 presses the pressure sensor 6 or the locking component 9. When the telescopic column 404 presses the pressure sensor 6, an alarm is triggered through the touch sensing component. When the telescopic column 404 presses the locking component 9, the locking component 9 moves backward and disengages from the surface of the lifting door 11. When the button head 403 is no longer pressed, the spring 405 rebounds, driving the limit slider 402 and the button head 403 to move forward and reset.

[0031] The touch sensing component includes a groove 5, a pressure sensor 6, a cable cavity 7, and a signal generator 8. The groove 5 is opened on the front surface of the sensing box 3. The number of grooves 5 is one less than the number of elastic extrusion structures 4. The groove 5 is located directly behind the telescopic column 404. The pressure sensor 6 is fixedly installed on the back surface of the inner wall of the groove 5. The cable cavity 7 is opened in the sensing box 3 and is communicated with several grooves 5. Small holes for threading are opened on the rear side walls of the grooves 5. A signal generator 8 for processing signals is fixedly installed on the inner surface of the wall of the cable cavity 7. The signal generator 8 is electrically connected to the pressure sensor 6.

[0032] Specifically, after the telescopic column 404 presses the pressure sensor 6, the pressure sensor 6 generates a pressure-induced electrical signal, which is transmitted to the signal generator 8 through a wire. Finally, after being processed by the signal generator 8, the signal is transmitted to the processor of the electric vehicle, thereby triggering an alarm. Through the cable cavity 7 and the small holes, different pressure sensors 6 can be connected to the signal generator 8 using wires.

[0033] The locking component 9 includes a moving groove 904, which is opened on the front surface of the sensing box 3 and is located directly behind a single telescopic column 404. A moving column 901 is slidably installed on the inner surface of the wall of the moving groove 904. A baffle 902 is fixedly installed on the back surface of the moving column 901. The baffle 902 penetrates through the back surface of the sensing box 3 and is slidably arranged. A locking block 903 is fixedly installed on the back surface of the baffle 902. The locking block 903 is of an L-shaped structure, and its horizontal part is slidably inserted into the back surface of the lifting door 11.

[0034] Specifically, when the telescopic column 404 moves backward, it drives the moving column 901 to slide backward in the moving groove 904, and further causes the baffle 902 and the locking block 903 fixedly installed on the back surface of the moving column 901 to move backward, so that the horizontal part of the locking block 903 slides away from the surface of the lifting door 11. On the premise that the lock body 18 has been opened, the lifting door 11 can slide upward.

[0035] A sliding connection member 12 is provided between the top plate 10 and the lifting door 11. The sliding connection member 12 includes a T-shaped slider 121 and a T-shaped chute 122. The T-shaped slider 121 is fixedly installed on the front surface of the top plate 10, the T-shaped chute 122 is opened on the back surface of the lifting door 11, the T-shaped slider 121 is slidably installed on the inner wall surface of the T-shaped chute 122, and a clamping groove 13 is opened on the back surface of the lifting door 11. The horizontal portion of the clamping block 903 is slidably inserted into the inner wall surface of the clamping groove 13.

[0036] Specifically, by sliding the T-shaped slider 121 in the T-shaped chute 122, the lifting door 11 can slide up and down stably and reliably along the front surface of the top plate 10. Furthermore, when the clamping block 903 is slidably inserted into the clamping groove 13, the lifting door 11 can be reliably fixed, so that the top plate 10 and the lifting door 11 are reliably locked.

[0037] A handle 14 is fixedly installed on the front surface of the lifting door 11, and a ventilation hole 15 and a wire passing hole 16 are opened on the side surface of the protection box 1.

[0038] Specifically, the handle 14 makes it more convenient to open the lifting door 11 and the top plate 10. The ventilation hole 15 facilitates the heat dissipation of the electric vehicle motor body 17 located inside the protection box 1, and the wire passing hole 16 is used to provide a wire passing space for the cables of the electric vehicle motor body 17.

[0039] In summary: By providing a plurality of elastic extrusion structures 4 on the front surface of the installation box 2, and only one elastic extrusion structure 4 will push the locking component 9 backward during the backward movement, so that the locking component 9 slides away from the surface of the lifting door 11. Then, use the key to open the lock body 18, and then the lifting door 11 can be slid upward to open the lifting door 11 and the top plate 10, which is convenient for the maintenance of the electric vehicle motor body 17 fixedly placed in the protection box 1. The remaining plurality of elastic extrusion structures 4 will squeeze the surface of the pressure sensor 6 during the backward movement. The pressure sensing signal generated by the pressure sensor 6 is processed by the touch sensing component and then transmitted to the processor of the electric vehicle. After being processed by the processor, an alarm is triggered, so that the vehicle owner can be informed in time.
