DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example

[0027] See Figures 1 to 4 As shown, a waterproof integrated electronic lock structure includes a lock housing 1 and a lock cover 2. A control circuit board is disposed in the lock housing. In this embodiment, the control circuit board is a conventional structure of the prior art and is simply applied. The lock cover is provided with a key area 3, a fingerprint recognition area 4 and a keyhole. The lock housing is provided with a circuit board box 5. The control circuit board 8 is located in the circuit board box and is sealed into a whole with glue. Through the above structure, the control circuit board can be processed into a whole, thereby improving the sealing and waterproof performance, and also facilitating the integration of the control circuit board, which is highly practical.

[0028] During assembly, the circuit board box is secured to the lock housing via screws. The box comprises a body 51 and a lid 52. The body is provided with several snap-fit ​​slots 53 along its edges, and the lid is integrally formed with several snap-fit ​​protrusions 54. The lid is connected to the body, and the snap-fit ​​protrusions snap into place within the snap-fit ​​slots. The control circuit board is located within the body and sealed with glue. Wire grooves 9 are provided on the bottom walls of the body and lid, and a wire pressing plate 10 is provided within the grooves. The wires of the control circuit board are threaded through the grooves and pressed into place by the wire pressing plate. This structure improves the stability and convenience of the connection. When maintenance is required, the lid can be opened for operation. Control buttons are provided on the body, located within the keypad area. A waterproof rubber pad 6 is provided on the inner surface of the lock lid, located at the interface between the lock lid and the circuit board box. This waterproof rubber pad improves the seal between the lock lid and the circuit board box, further enhancing waterproof performance and enhancing practicality.

[0029] In actual use, a waterproof rubber ring is installed at the connection between the lock housing and the lock cover. A sealing ring slot 7 is provided on the front edge of the lock housing. During assembly, the waterproof rubber ring is locked in the sealing ring slot. When the lock cover is connected to the lock housing, the end edge of the lock cover abuts against the waterproof rubber ring. This improves the sealing and waterproof performance of the connection between the lock housing and the lock cover, and enhances stability and reliability in use.

[0030] In actual application, the circuit board box is a plastic structure, and the buttons on the control circuit board pass through the circuit board box and are located in the button area, thereby improving the effectiveness and sealing of the overall structure.

[0031] The utility model has positive effects: the structure of the utility model is reasonably set up, and a circuit board box is provided, and the circuit board is placed in the circuit board box and sealed into a whole with glue, which is beneficial to improving the overall waterproof, anti-fog, anti-freeze, anti-condensation, moisture-proof, sun-proof and dust-proof performance. In addition, the provision of a waterproof pad can further improve the overall waterproof stability, and it has strong applicability and good practicality.

[0032] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0033] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
