[0025] like Figures 1-6 As shown, a new type of electronic lock includes:

[0026] A semi-finished face cover assembly 1 includes a face cover 11, a motor assembly 14 fixed inside the face cover 11, and a locking rod 15 connected to the end of the output shaft of the motor assembly 14. The lower end of the face cover 11 away from the locking rod 15 has an upper glue-filling cavity 17. Motor fixing bones 13 protrude from both the front and rear sides of the inner wall of the face cover 11. The motor assembly 14 is located between the motor fixing bones 13 and is fixedly connected to the motor fixing bones 13. The lower part of the upper glue-filling cavity 17 away from the locking rod 15 has multiple upper wire fixing grooves 16. The wires of the motor assembly 14 extend through the upper wire fixing grooves 16. The motor assembly 14 is fixed between the motor fixing bones 13 inside the face cover 11, and the wires of the motor assembly 14 pass through the upper wire fixing grooves 16, so that the motor assembly 14 and its wires are integrated on the face cover 11.

[0027] A bottom cover semi-finished assembly 2 is fixed to the lower end of the top cover semi-finished assembly 1. The bottom cover semi-finished assembly 2 includes a bottom cover 21, a mechanical switch 23 fixed to the outside of the bottom cover 21, and a signal switch 26 fixed to the inside of the bottom cover 21. The bottom cover 21 has a lower glue filling cavity 27 located directly below the upper glue filling cavity 17 at its upper end. The inner wall of the lower glue filling cavity 27 has a glue filling hole 24 communicating with the outside. The bottom cover 21 has an outer switch fixing groove 22, and a mechanical switch fixing post is fixed to the bottom of the outer switch fixing groove 22. The mechanical switch 23 is located inside the outer switch fixing groove 22 and is fixedly connected to the mechanical switch fixing post. The bottom cover 21 has an inner switch fixing groove 25, and a signal switch fixing post is fixed to the bottom of the inner switch fixing groove 25. The signal switch 26 is located inside the inner switch fixing groove 25 and is fixedly connected to the signal switch fixing post. Multiple lower wire fixings are located on the upper left side of the lower glue filling cavity 27. The wires of the signal switch 26 and the mechanical switch 23 extend through the lower wire fixing groove 28. The number and distribution of the lower wire fixing groove 28 correspond one-to-one with the number and distribution of the upper wire fixing groove 16. The mechanical switch 23 is fixed inside the outer switch fixing groove 22 by the mechanical switch fixing post, while the signal switch 26 is fixed inside the inner switch fixing groove 25 by the signal switch fixing post. The wires of the mechanical switch 23 and the signal switch 26 pass through the lower wire fixing groove 28. In this way, the mechanical switch 23 and the signal switch 26 and their wires are integrated on the bottom cover 21. This allows for separate functional testing of the front cover semi-finished component 1 and the bottom cover semi-finished component 2. After testing, the front cover semi-finished component 1 and the bottom cover semi-finished component 2 can be assembled. In this way, the front cover semi-finished component 1 and the bottom cover semi-finished component 2 form two independent semi-finished products, increasing the convenience of finished product assembly and reducing the generation of defective products.

[0028] A waterproof component 3 is embedded and installed on the upper end of the cover 11. The waterproof component 3 is sleeved on the outside of the output shaft. By setting the waterproof component 3, the waterproof performance between the output shaft and the cover 11 can be improved.

[0029] like Figures 1-5 As shown, a lever is fixed to the outside of the output shaft of the motor assembly 14. The lever is located on one side of the waterproof assembly 3. The lever can trigger the button of the signal switch 26. During the process of the motor assembly 14 driving the locking lever 15 to rotate and lock, the lever can trigger the button of the signal switch 26 to send a locked signal.

[0030] like Figures 1-6As shown, the lower glue-filling cavity 27 and the upper glue-filling cavity 17 form an internal glue-filling area. The glue-filling hole 24 is connected to the external switch fixing groove 22. After the front cover semi-finished component 1 and the bottom cover semi-finished component 2 are fixed, glue can be poured into the interconnected internal glue-filling area formed by the lower glue-filling cavity 27 and the upper glue-filling cavity 17 through the glue-filling hole 24, so that the glue wraps the wire, thereby achieving the internal and external waterproof function.

[0031] like Figures 1-2 As shown, a silicone ring groove 12 is formed on the upper end of the cover 11 near the locking rod 15. The output shaft of the motor assembly 14 moves through the silicone ring groove 12. The waterproof assembly 3 includes a waterproof silicone ring 31, a bracket mounting groove 32, and a bracket 33. The waterproof silicone ring 31 is fitted over the output shaft of the motor assembly 14 and inserted into the silicone ring groove 12. A bracket mounting groove 32 is formed on the outer wall of the waterproof silicone ring 31. The bracket 33 is installed inside the bracket mounting groove 32. Installing the bracket 33 inside the bracket mounting groove 32 increases the hardness of the waterproof silicone ring 31. Inserting the waterproof silicone ring 31 into the silicone ring groove 12 allows the output shaft to pass through the silicone ring groove 12 when installing the motor assembly 14, thus improving the waterproofness between the output shaft of the motor assembly 14 and the cover 11.
