The fixing method of the above functional modules has also changed from the previous single panel to a multi-fixed panel structure, which ensures strength and easy assembly and disassembly while ensuring functionality.

[0004] At present, the functional modules of electronic locks are installed on the panel structure, and the panel structure with the functional modules needs to be disassembled and assembled as a whole during disassembly and assembly, which makes the installation and disassembly more complicated and inefficient. For example, the invention patent with patent application number 201721257057.5 discloses a panel lock, including: a panel with a shaft mounting hole; a shaft that can be pivotally inserted into the shaft mounting hole; a locking structure that is connected to the shaft driving, and the locking structure is in a locked or unlocked state through the pivoting movement of the shaft; a handle that is detachably connected to the shaft, and the shaft is pivoted by rotating the handle; an electronic locking module that is arranged on the inner side of the panel, and the electronic locking module has a locked state and an unlocked state. When the electronic locking module is in the locked state, the electronic locking module locks the shaft to make the shaft fixed; when the electronic locking module is in the unlocked state, the electronic locking module releases the shaft, and the shaft can pivot relative to the shaft mounting hole.

[0005] However, as can be directly seen from the drawings of the disclosed specification, the connection relationship between the various components of the electronic lock is fixed by screws, so a professional screwdriver is required for connection during the assembly process, and electronic locks often require professionals to install on-site. Therefore, how to improve the convenience of installation and operation of smart door locks and improve installation efficiency is a technical problem that technical personnel in this field need to solve.

The end of the clutch pin 402 away from the driver 403 corresponds to the locking opening 1041. A concave locking groove 305 is provided on the outer wall of the handle turn block 302 on one side facing the clutch assembly 400. When the driver 403 drives the clutch pin 402 to move linearly, the clutch pin 402 passes through the locking opening 1041 to abut or disengage from the locking groove 305 of the handle turn block 302. When the clutch pin 402 abuts against the locking groove 305, the handle turn block 302 is limited in the circumferential direction and thus locked. When the clutch pin 402 disengages from the locking groove 305, the handle turn block 302 can be rotated and thus unlocked.

[0072] Reference Fig.10 and Fig.16The rotation limiting mechanism includes an elastic limiting member 801 and a limiting groove 802. The limiting groove 802 is arranged on the outer circumferential surface of the handle rotating block 302. Two limiting grooves 802 are arranged at intervals along the circumferential direction. One end of the elastic limiting member 801 is connected to the mounting seat 100 or the handle cover plate 200, and the other end is provided with a limiting protrusion 8011 which always has a tendency to elastically abut against the outer circumferential surface of the rotating block. When the limiting protrusion 8011 elastically abuts against the limiting groove 802, the limiting protrusion 8011 limits the handle rotating block 302 in the circumferential direction. Since the limiting protrusion 8011 has a certain elasticity, when the handle rotating block 302 rotates under the action of external force, the limiting protrusion 8011 can be separated from the limiting groove 802 and thus elastically abut against the outer circumferential surface of the handle rotating block 302. The elastic limiting member 801 in this embodiment is arranged on the handle cover plate 200. The elastic limiting member 801 is an arc-shaped plate body. The arc-shaped plate body is perpendicular to a side surface of the handle cover plate 200 facing the mounting seat 100 and one end of the arc-shaped plate body is integrally connected to the handle cover plate 200. The limiting protrusion 8011 is integrally connected to the other end of the arc-shaped plate body. An arc-shaped opening is opened on the handle cover plate 200 at a position corresponding to the position of the arc-shaped plate body, so that the end of the arc-shaped plate body close to the limiting protrusion 8011 is cantilevered and has a certain elasticity. The distance between the end of the arc-shaped plate body away from the limiting protrusion 8011 and the outer cylindrical surface of the handle turn block 302 gradually decreases to zero to the distance between the limiting protrusion 8011 and the outer cylindrical surface of the handle turn block 302, so that the limiting protrusion 8011 is always elastically abutted against the outer cylindrical surface of the handle turn block 302.

[0073] The rotation limit mechanism also includes an angle limit assembly, which includes a limit block 803 and an arc-shaped limit groove 804. The limit block 803 is integrally arranged on the annular abutment surface 107 and is located at the limit opening 1042. The arc-shaped limit groove 804 is opened on the step surface 304 and passes through the outer cylindrical surface of the handle turn block 302. The arc-shaped limit groove 804 is coaxial with the center line of the handle turn block 302. When the handle turn block 302 is installed in the first installation cavity, the limit block 803 is limited in the arc-shaped limit groove 804, and the two limit grooves 802 are respectively close to the two ends of the arc-shaped limit groove 804. In this embodiment, when the handle turn block 302 is rotated, when the limit block 803 abuts against one end of the arc-shaped limit groove 804, the limit protrusion 8011 elastically abuts against the limit groove 802 near the end of the arc-shaped limit groove 804, and at this time, the locking groove 305 corresponds to the locking opening 1041; when the handle turn block 302 is rotated in the reverse direction, when the limit block 803 abuts against the other end of the arc-shaped limit groove 804, the limit protrusion 8011 elastically abuts against the other limit groove 802, and at this time, the locking groove 305 deviates from the locking opening 1041.

[0074] Reference Fig.17 and Fig.18When the handle turning block 302 is in use, since the handle turning block 302 rotates on the base 101, it will be worn after a period of use. Therefore, a washer 900 is arranged between the step surface 304 and the annular abutting surface 107, and the washer 900 includes a circular tube portion 901 and an annular portion 902 integrally connected to one end of the circular tube portion 901. The circular tube portion 901 is installed in the mounting hole 111, and the two side surfaces of the annular portion 902 abut against the step surface 304 and the annular abutting surface 107 respectively. On the abutment surface 107, a positioning groove 903 corresponding to the limit block 803 is provided on the annular portion 902 of the gasket 900. When the gasket 900 is assembled on the step surface 304 and the annular abutment surface 107, the limit block 803 is correspondingly embedded in the positioning groove 903, so that when the handle turn block 302 rotates, the gasket 900 will not rotate with the handle turn block 302. After using it for a period of time, you only need to replace the gasket 900, thereby extending the service life of the handle turn block 302.

[0075] The control principle of the password control module 22 adopts the existing conventional technology and will not be described in detail in this embodiment. Structurally, it includes a circuit board 221 and a key board 222 fixedly connected to the circuit board 221. Sliders 122 are provided on the side walls of the circuit board 221 facing the two side panels 12, and the circuit board 221 and each key on the key board 222 pass through.

[0076] The electronic lock also includes a decorative panel 3, which covers the opening on the side of the installation cavity away from the bottom plate 11. The decorative panel 3 is provided with a key slot corresponding to the key plate 222 and a through hole for the handle component 500 to pass through. The edges of the decorative panel 3 facing the two side plates 12 are correspondingly abutted against the edges of the side of the two side plates 12 away from the bottom plate 11 and are fixed by glue.
