[0027] As Figure 1-6 It is a schematic structural diagram of a switch lock with precise positioning in a preferred embodiment of the present utility model. In this embodiment, a switch lock with precise positioning includes a lock box 1. An installation cavity 11 is opened at the front end of the lock box 1. An installation position 13 is opened on one side inside the installation cavity 11. A motor 5 is assembled in the installation position 13 by screw connection. A rotation position 12 is fixedly installed at the center inside the installation cavity 11. A gear 2 is rotatably connected to the rotation position 12, and the gear 2 is meshed with the output gear at the bottom of the motor 5. A knob structure 3 is rotatably connected to the middle of the gear 2. A circuit board 4 is fixedly installed at the front end of the gear 2 inside the installation cavity 11. A connecting plate 6 is clamped at the opening of the installation cavity 11. A sealing plate 7 is fixedly connected to the outer wall surface of the connecting plate 6, which serves to protect the components inside the installation cavity 11.
[0028] In this embodiment, a connection hole 21 is opened on the surface of the gear 2, and the knob structure 3 is rotatably connected in the connection hole 21. A semi-circular arc groove 22 is opened on the surface of the gear 2 directly below the connection hole 21.
[0029] In this embodiment, a fixing block 31 is fixedly connected to the upper part of the outer wall of the knob structure 3. A threaded hole is opened on the surface of the fixing block 31. One end of the outer wall of the knob structure 3 is fixedly connected to a magnet installation position 32. A magnet 33 is installed in the magnet installation position 32. A connection groove 34 is opened on the top surface of the knob structure 3.
[0030] In this embodiment, a Hall element 41 is soldered on the surface of the circuit board 4.
[0031] In this embodiment, a battery installation cavity 14 is provided above the rear end of the lock box 1. A battery 15 is installed in the battery installation cavity 14. A protective cover 9 is slidably connected to the opening of the battery installation cavity 14. This structural design provides a protective effect on the battery 15.
[0032] In this embodiment, a knob 8 is rotatably connected to the surface of the rear end of the lock box 1 at a position opposite to the rotation position 12. A connecting rod 81 is fixedly connected to the bottom of the knob 8. The connecting rod 81 passes through the lock box 1 and is connected to the knob structural member 3. A connecting hole 82 is provided on the surface of the connecting rod 81. The connecting hole 82 and the threaded hole 35 are fixedly connected by a fastener 36. This structural design enables the rotation function of the knob structural member 3 to be realized through the operation of the knob 5.
[0033] In this embodiment, a connection position 23 is provided on the surface of the rear end of the gear 2. A clutch limiting piece 24 is assembled in the connection position 23. This structural arrangement functions as a clutch and a limit, assisting the rotation of the knob 8 and the motor 5, thereby effectively solving the problems of the knob 8 not being able to rotate or the motor 5 not being able to stall.
[0034] Working principle
[0035] During specific use, when driven by the motor 5, the motor 5 rotates electrically and drives the gear 2 to rotate together. When the edge of the semi-circular arc groove 22 of the gear touches the fixed block 31 in the knob structural member 3 placed in the semi-circular arc groove 22, it will drive the knob structural member 3 to rotate, thereby driving the lock tongue placed in the connection groove 34 at the top of the knob structural member 3 to rotate, so as to realize the function of the motor 5 driving the door lock.
[0036] When unlocking is driven by the motor 5, the magnet 33 placed in the magnet installation position 32 below the knob structural member 3 will rotate together. When the magnet 33 rotates above the Hall element 41 on the circuit board 4, the motor 5 stops operating to achieve the effect of precise positioning and prevent damage to the structure caused by excessive rotation.
[0037] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
