[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] The following is for reference. Figures 1 to 9 A mechanical and electronic dual-purpose combination lock according to an embodiment of the present invention includes a housing 1 and a keypad assembly 2. The keypad assembly 2 is mounted on the housing 1. The housing 1 has a mounting compartment 4, which has a battery cavity 402 and a lock cylinder mounting cavity 404. A mechanical lock cylinder 5 is installed in the lock cylinder mounting cavity 404. The mechanical lock cylinder 5 is connected to a push plate 501. The upper surface of the push plate 501 has a push plate protrusion 502, and the push plate protrusion 502 is fitted with a protrusion spring 503. A magnet 6 is provided at the top of the mounting compartment 4. The top of the outer casing 1 is provided with a guide tube 3. Inside the guide tube 3 are a frame 10, a telescopic motor 7, a telescopic rod 701, a pin 702, a return spring 703, a moving guide 8, and an opening part 9. The moving guide 8 and the opening part 9 are connected. The telescopic motor 7 is fixed to the frame 10 and connected to the telescopic rod 701. The pin 702 and the return spring 703 are installed on the telescopic rod 701. The surface of the moving guide 8 is provided with a guide groove 801, and one end of the pin 702 is placed in the guide groove 801.
[0028] This structure uses a telescopic motor 7 or a mechanical lock cylinder 5 to push the opening element 9 out of the guide tube 3, achieving both mechanical and electronic operation for ease of use. The telescopic motor 7 is controlled by the button panel assembly 2. After the password is entered into the button panel assembly 2, the button panel assembly 2 outputs voltage to start the telescopic motor 7. The telescopic rod 701 of the telescopic motor 7 moves forward. When the telescopic rod 701 touches the bottom surface of the opening element 9, the opening element 9 and the moving guide 8 move together within the guide tube 3, so that the opening element 9 is finally exposed outside the guide tube 3. The opening element 9 is placed in the recess of the lock body, and the entire outer shell 1 can be twisted to rotate, thereby opening the lock body.
[0029] Additionally, a conductive spring is installed inside the battery cavity 402. The spring is connected to the button panel assembly 2 via a conductive wire, and the button panel assembly 2 is connected to the telescopic motor 7 via a conductive wire. A battery is placed in the battery cavity 402, and the conductive spring is connected to the battery electrodes to supply power to the button panel assembly 2. One end of the pin 702 is placed in the guide groove 801 of the moving guide member 8. The pin 702 moves within the guide groove 801. When the telescopic rod 701 retracts, the pin 702 presses against the inner wall of the guide groove 801, causing the moving guide member 8 to return to its original position.
[0030] When frame 10 is close to magnet 6, magnet 6 acts on frame 10, and magnet 6 is magnetically attracted to frame 10, which drives frame 10 to reset.
[0031] Furthermore, when the mechanical lock cylinder is opened, the protruding spring 502 on the push plate 501 acts as a buffer. When the opening part is under pressure, the opening part retracts towards the guide tube to avoid the opening part from making strong contact with the lock cylinder and causing wear.
[0032] The mounting chamber 4 of this structure is fixed with a positioning guide post 401. The push plate 501 is provided with a guide hole 504, through which the positioning guide post 401 passes. The positioning guide post 401 is used to limit the direction of the push plate 501's vertical movement, ensuring that the push plate 501 and the protruding spring 503 can correspond to the position of the frame 10. When the push plate 501 moves upward, the protruding spring 503 can push the frame 10 to move, causing the frame 10 to push the telescopic motor 7, the moving guide 8, and the opening part 9 to move together. Finally, the opening part 9 is exposed outside the guide tube 3.
[0033] The mounting compartment 4 of this structure has a through-hole 403, which corresponds to the mechanical lock cylinder 5. The key can pass through this through-hole 403 and be inserted into the mechanical lock cylinder 5, allowing the mechanical lock cylinder 5 to be pushed inwards.
[0034] The front end of the guide tube 3 of this structure is provided with two guide protrusions 301, and the opening member 9 is located between the two guide protrusions 301.
[0035] The guide member 8 of this structure is provided with a shaft hole 803, and one end of the telescopic rod 701 passes through the shaft hole 803.
[0036] The opening member 9 of this structure has an opening recess 902. One end of the telescopic rod 701 passes through the movable guide member 8 and is positioned within the opening recess 902. The opening recess 902 restricts the position of one end of the telescopic rod 701. The side wall of the movable guide member 8 of this structure has a guide recess 802, and the opening member 9 has a locking head 901, which is fastened onto the guide recess 802. The opening member 9 is connected to the movable guide member 8 and moves together during movement.
[0037] The top of the mounting compartment 4 in this structure is glued to the magnet 6 to fix the position of the magnet 6. The inner wall of the lock cylinder mounting cavity 404 in this structure has a notch 405 through which the push plate 501 passes. The notch 405 is used to limit the range of movement of the push plate 501 and prevent the push plate 501 from deviating from its direction when moving.
[0038] The button panel assembly 2 described in this structure includes a sealant 201, a button housing 202, a circuit board 203, and a digital tube 204. The digital tube 204 is mounted on the circuit board 203, and the sealant 201 and the button housing 202 are sequentially mounted on the circuit board 203. The sealant 201 serves a sealing function, and the digital tube 204 displays the operating status.
[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
