Description

Technical Field

[0001] The utility model relates to a clutch module for magnetic attraction positioning. Background Art

[0002] Prior art, such as Chinese utility model patent document with publication number CN212201643U, discloses a clutch device of a fingerprint lock, comprising: a lock seat for mounting a lock core, a handle being rotatably connected to the lock seat; a square shaft connecting block, an upper end of which is movably inserted into the handle and a lower end of which is connected to the lock core; a driving assembly, which is vertically fixed in the handle; a clutch assembly, which is vertically arranged in the handle, a clutch spring is arranged at the upper end of the clutch assembly, the clutch spring is connected to the driving assembly, and a transmission block is arranged at the lower end of the clutch assembly; when the driving assembly is working, the clutch spring can be driven to be compressed, and when the clutch spring is compressed, the transmission block can be driven to move downward and the lower end of the transmission block is inserted into the square shaft connecting block.

[0003] In the prior art, when the square shaft is not inserted into the square hole, the handle can rotate relative to the square shaft connecting block at will, and it will not drive the square shaft connecting block to rotate, so that the lock cannot be unlocked. When unlocking, the driving motor can drive the transmission block to move vertically downward until the square shaft is inserted into the square hole. At this time, the rotation of the handle will drive the square shaft connecting block to rotate, and the unlocking action can be performed.

[0004] Based on the above, the problem with the existing clutch structure is that the handle can be rotated at will in the clutch disengaged state. Although the handle has elastic elements such as torsion springs to constrain its reset, as the elastic force of the elastic elements decays, there may be position deviation when the handle is rotated to reset, resulting in the square shaft and the square hole not being 100% aligned. In this case, when the driving motor drives the square shaft to move, there may be a situation where it cannot be plugged into the square hole, which needs further improvement. Utility Model Content

The setting of the plane 510 can create space for the arrangement of the wiring groove 100. The setting of the wiring groove 100 is to realize the wiring of the driving motor 50. The control wire of the driving motor 50 needs to pass through the wiring groove 100 and extend forward to the indoor lock body for power connection.

[0027] See Figure 1 and Figure 2 Figure 2 , the integrated housing 10 includes an upper housing 110 and a lower housing 120 which are connected to each other;

[0028] A positioning plug post 111 is provided on the front lower wall surface of the upper housing 110, and a plug hole 121 which is plugged with the positioning plug post 111 is provided on the front upper wall surface of the lower housing 120;

[0029] A fixed collar 130 is sleeved on the rear parts of the upper housing 110 and the lower housing 120;

[0030] Mounting positioning ear seats 140 are respectively provided on the left and right on the outer wall of the upper housing 110 and the outer wall of the lower housing 120.

[0031] With the above structure for the upper housing 110 and the lower housing 120, screwless assembly can be realized. The fixed collar 130 can restrict the connection between the upper housing 110 and the lower housing 120.

[0032] The function of the mounting positioning ear seats 140 is to be used for positioning and assembling with the outdoor lock body.

[0033] See Figure 2 Figure 2 , both the front and rear ends of the wiring groove 100 are open. The open setting can not only facilitate demolding better, but also be convenient for wire routing.

[0034] Furthermore, the wiring groove 100 is provided on the upper housing 110.

[0035] See Figure 2 and Figure 4, the rear side of the integrated housing 10 is provided with an opening, a manual trigger 410 is movably arranged inside the integrated housing 10, the rear end of the manual trigger 410 passes through the opening at the rear side of the integrated housing 10 and extends to the rear of the integrated housing 10, a first elastic element 420 for applying a backward acting force to the manual trigger 410 is arranged inside the integrated housing 10, and a second elastic element 430 is connected between the front end of the manual trigger 410 and the second clutch 30.

[0036] The function of the manual trigger 410 is that when the drive motor 50 cannot operate, the manual trigger 410 can be pushed forward by a tool, so as to push the second clutch 30 forward through the second elastic element 430, so as to realize the plug-in fit of the second clutch 30 with the first clutch 20 forward.

[0037] See Figure 4 , the manual trigger 410 includes two drive rods 411, a trigger rod 412 is connected to the rear ends of the two drive rods 411, and the drive rods 411 are arranged to move back and forth relative to the integrated housing 10;

[0038] The trigger rod 412 is arranged behind the integrated housing 10;

[0039] Two second elastic elements 430 are provided and are respectively connected to the drive rods 411.

[0040] Further, sliding tracks are respectively integrated on the left and right inside the integrated housing 10, and the drive rods 411 are slidably arranged in the sliding tracks. When the drive rods 411 are moved to the frontmost end of the sliding tracks, the drive rods 411 push the second clutch 30 to be plugged and coupled with the first clutch 20. In this process, the second elastic element 430 will be compressed and store energy. When the manual trigger 410 is released, the second elastic element 430 will drive the drive rods 411 back to the rearmost end of the sliding tracks.

[0041] See Figure 1 and Figure 2 , the first clutch 20 is fixedly connected with a square rod 200 for connecting the lock tongue and the indoor lock.

[0042] See Figure 3, a drive rod 520 is installed on the motor shaft of the drive motor 50. A spring 530 is sleeved on the drive rod. The second clutch 30 is slidably arranged at the front end of the drive rod 520. The front end of the spring 530 is connected to the second clutch 30. A drive pin 540 is arranged on the drive rod 520, and the drive pin 540 is inserted into any pitch of the spring 530. When the drive motor 50 drives the drive rod 520 to rotate, the drive pin 540 rotates along with the drive rod 520. Under the action of the drive pin 540, it drives the spring 530 to move forward, and the second clutch 30 is pushed forward by the spring 530.
