[0029] like Figures 1 to 6As shown, this embodiment provides an electronic lock rear handle reset module. The rear handle reset module is installed inside an indoor electronic lock. The handle is connected to the reset module to drive the lock body inside, thereby opening the lock. The rear handle reset module includes a housing 1, a handle head 2, a rotating plate 3, and a reset spring 4. The housing 1 is fixed inside a bottom housing 7. One side of the housing 1 is an opening. A first through hole 11 is provided in the middle of the housing 1. The handle head 2 is located in the first through hole 11 and rotates within the first through hole 11. The rotating plate 3 and the reset spring 4 are located inside the housing 1 and are sleeved on the handle head 2. A driving plate 31 is provided at the top of the rotating plate 3. A baffle 12 is provided inward in the housing 1. The two ends of the reset spring 4 are clamped on the driving plate 31 and the baffle 12. When the handle head 2 drives the rotating plate 3 to rotate, the driving plate 31 constrains the reset spring 4. When the first end of the handle rotates, the other end of the return spring 4 will rest against the baffle 12. During the rotation, the two ends of the return spring 4 will separate to generate pressure. When the handle head 2 is released, the two ends of the return spring 4 will come together to achieve the effect of reset. The rotating plate 3 is engaged and fixedly connected with the handle head 2. The rotation of the handle head 2 drives the rotating plate 3 to rotate. A bushing 5 is provided between the first through hole 11 and the handle head 2. The bushing 5 can reduce the friction between the outer shell 1 and the handle head 2. A step 13 is provided in the first through hole 11. The step 13 can restrict the bushing 5 from sliding in one direction. A protruding ring 21 is provided on the surface of the handle head 2. The protruding ring 21 can restrict the other end of the bushing 5 from sliding. The bushing 5 is located between the step 13 and the protruding ring 21. By using the bushing 5, friction can be reduced, noise can be reduced, service life can be improved, and the handle head can be prevented from shaking.

[0030] As an optional embodiment, the bushing 5 can be a plastic ring or a bearing, both of which can achieve a noise reduction effect and reduce friction.

[0031] As an optional embodiment, a retaining spring 6 is installed at the end of the handle head 2. The retaining spring 6 is used to prevent the rotating piece 3 from falling off. There is an annular groove at the end of the handle head 2. The retaining spring 6 will be inserted into the annular groove to fix it.

[0032] As an optional embodiment, the outer shell 1 is provided with blocks 14 on both sides. The blocks 14 restrict the rotating piece 3 from continuing to rotate. During the rotation of the rotating piece 3, in order to reach the range of the set rotation angle of the handle head 2, the handle is provided with a block 14. The block 14 is integral with the outer shell 1 and is stamped. The block 14 is inclined inward, which solves the problem that the vertical block 14 in the prior art is prone to deformation during use. The inward inclination of the block 14 can increase the pressure force and make it less prone to deformation.

[0033] As an optional embodiment, the handle head 2 is provided with slots 22 on both sides, and the rotating plate 3 is provided with a locking block 32 on the inner side. The locking block 32 is locked into the slots 22 for fixation. This facilitates the rotation of the handle head 2 to drive the rotating plate 3 to rotate, making installation convenient.

[0034] As an optional embodiment, a limiting protrusion 15 is provided in the first through hole 11, and a notch 51 is provided on the bushing 5 corresponding to the limiting protrusion 15. The limiting protrusion 15 and the notch 51 are connected to each other to restrict the rotation of the bushing 5.

[0035] As an optional embodiment, the front end of the protruding ring 21 of the handle head 2 is a square structure, and the surface of the square structure is recessed 23. The square structure is positioned to install the handle, and the recessed 23 is positioned to facilitate the installation of the handle.

[0036] As an optional embodiment, it also includes a bottom shell 7, which is used to fix it to the door panel. A positioning protrusion 16 is provided at the contact position between the outer shell 1 and the bottom shell 7. The positioning protrusion 16 is to facilitate the installation of the outer shell 1 on the bottom shell 7, and to make the installation more secure and less likely to fall off.

[0037] As an optional embodiment, the surface of the outer shell 1 is provided with a plurality of screw holes 17. After the screw passes through the bottom shell 7, it is threadedly connected to the screw holes 17 of the outer shell 1. The existing installation method is that the screw passes through the outer shell 1 and the screw is threadedly connected to the bottom shell 7. This has the problem of being unstable because the thickness of the bottom shell 7 is relatively thin, and the area of ​​the threaded connection is limited, making it easy to loosen and fall off. If the bottom shell 7 is made thicker, the cost will be high. Therefore, the screw installation direction is adjusted, and the screw is threadedly connected to the outer shell 1 more securely. The outer shell 1 is connected to the handle head 2 and is provided with a stop block 14, so the outer shell 1 can be thicker than the bottom shell 7.

[0038] In the prior art, the contact between metal surfaces can easily cause friction, resulting in noise. Over time, wear and tear can occur, causing the handle head to wobble. Therefore, an electronic lock rear handle reset module is provided. By setting a bushing 5 between the first through hole 11 of the outer shell 1 and the handle head 2, the bushing 5 can reduce the friction between the outer shell 1 and the handle head 2, reduce noise, improve service life, and prevent the handle head from wobble.

[0039] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
