Description

Technical Field

[0001] The utility model relates to the field of intelligent door locks, and in particular to an intelligent door lock clutch protection device. Background Art

[0002] With the widespread adoption of smart door locks in home security, the designs of smart door locks on the market are increasingly focused on user convenience and intelligence. However, most current smart door lock panels are typically made of plastic. While plastic panels offer advantages such as lightness and ease of processing, they lack significant protection and damage resistance. In actual use, if the door lock panel is pried open, the clutch components are exposed and easily damaged. This can not only render the door lock inoperable but also pose serious risks to property safety.

[0003] The clutch is a key component of smart door locks, responsible for opening and closing the lock under the control of electronic signals. However, because the clutch is typically fixed directly to the assembly cavity inside the door lock, it is the first component to bear the brunt of the force when the door lock panel is pried open, making it vulnerable to direct damage or failure. Therefore, how to effectively protect the clutch and prevent its exposure and damage caused by panel breakage has become a key issue in improving the security of smart door locks. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides an intelligent door lock clutch protection device. By adding a protective cover on the outside of the clutch and adopting a positioning installation structure, it can not only significantly enhance the anti-destruction ability of the clutch, but also ensure the stable connection between the protective cover and the shell, thereby improving the overall safety performance of the door lock and reducing the risk of the clutch being damaged.

[0005] The utility model is realized by the following technical solutions: an intelligent door lock clutch protection device, comprising a housing, wherein the housing has an assembly cavity for installing a clutch;

[0006] a clutch, the clutch being fixedly mounted in the assembly cavity;

[0007] A protective cover is installed in the assembly cavity and wrapped around the outside of the clutch. The protective cover is fixedly connected to the housing, and the clutch shaft of the clutch passes through the protective cover.

[0008] As a preferred technical solution, a first screw hole is provided on the protective cover, and a second screw hole is provided on the shell corresponding to the first screw hole, and the protective cover is locked and fixed to the shell by screws.

[0009] As a preferred technical solution, the protective cover has an extension portion, which extends in a direction away from the clutch. A bending portion is provided at one end of the extension portion, and the bottom end surface of the bending portion is positioned and mounted on the bottom surface of the assembly cavity.

[0010] As an optimal technical solution, the bottom end surface of the bent portion and the positioning and mounting surface of the shell are both provided with positioning protrusions, and the positions of the shell corresponding to the positioning protrusions are both provided with positioning recesses, and the positioning protrusions are snapped into the positioning recesses to complete the positioning.

[0011] As a preferred technical solution, the protective cover is a metal protective cover, and an axial hole is provided at the upper end thereof corresponding to the position of the clutch shaft, and the clutch shaft passes through the axial hole.

[0012] The beneficial effect of the present invention is that the present invention not only significantly enhances the anti-destruction ability of the clutch by adding a protective cover on the outside of the clutch and adopts a positioning installation structure, but also ensures a firm connection between the protective cover and the shell, thereby improving the overall safety performance of the door lock and reducing the risk of the clutch being damaged.

[0018] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 and Figure 2 As shown, an intelligent door lock clutch protection device of the present invention includes a housing 1, wherein the housing 1 has an assembly cavity 8 for installing a clutch 91;

[0021] It also includes a clutch 91, which is fixedly installed in the assembly cavity 8;

[0022] The protective cover 3 is installed in the assembly cavity 8 and wrapped around the outside of the clutch 91. The protective cover 3 is fixedly connected to the housing 1, and the clutch shaft 2 of the clutch 91 passes through the protective cover 3.

[0023] In this embodiment, a first screw hole 4 is provided on the protective cover 3, and a second screw hole is provided on the shell 1 corresponding to the first screw hole. The protective cover 3 is locked and fixed to the shell 1 by screws. Of course, other fixing methods can also be used.

[0024] In order to prevent the protective cover 3 from affecting the position of other components and to increase the stability of the protective cover 3 after installation, in this embodiment, the protective cover 3 has an extension portion 5, which extends in a direction away from the clutch 91. A bending portion 6 is provided at one end of the extension portion 5, and the bottom end surface of the bending portion 6 is positioned and installed with the bottom surface of the assembly cavity 8. During installation, one end of the protective cover 3 is first positioned and installed, and then the screws are tightened to fix it. This is very convenient and can effectively prevent the displacement of the protective cover 3.

[0025] Among them, Figure 2 As shown, the bottom end surface of the bending portion 6 and the positioning and installation surface of the shell 1 are both provided with positioning protrusions 7, and the positions corresponding to the positioning protrusions 7 on the shell 1 are both provided with positioning recesses, and the positioning protrusions 7 are snapped into the positioning recesses to complete the positioning.

[0026] In this embodiment, in order to improve the overall strength of the protective cover 3, the protective cover 3 is a metal protective cover, and an axial hole 9 is provided at the upper end thereof corresponding to the position of the clutch shaft 2. The clutch shaft 2 passes through the axial hole 9, and the protective cover 3 can completely wrap the clutch 91. When the panel of the smart door lock is damaged, the clutch 91 can also be protected by the protective cover 3 to prevent the clutch 91 from being damaged and opening the smart door lock.

[0027] The utility model adds a protective cover to the outside of the clutch and adopts a positioning installation structure, which not only significantly enhances the anti-destruction ability of the clutch, but also ensures a stable connection between the protective cover and the shell, thereby improving the overall safety performance of the door lock and reducing the risk of the clutch being damaged.
