Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a reversible clutch device and a smart lock. Background Technology

[0002] Smart locks generally control the on / off state of the transmission system by incorporating a clutch mechanism between the handle and the lock body. This clutch mechanism is typically installed inside the smart lock's panel. Existing clutch mechanisms usually consist of a base shell, a clutch assembly, and a cover plate. In practical installation, some smart locks on the market use a forward-mounted method: a positioning post is installed on the front panel shell, passing through the clutch assembly's base shell and then screwed onto the cover plate, thus clamping and fixing the base shell and cover plate to the front panel shell. Other smart locks use a reverse-mounted method: the clutch assembly's cover plate is directly attached to the back panel shell, and then screwed from the back panel shell to the cover plate for connection and fixation.

[0025] Reference Figure 5 and Figure 6According to a first aspect of the present invention, a reversible clutch device includes a base shell 110 and a clutch assembly 120. The base shell 110 has a mounting cavity 111. One end of the base shell 110 has at least two cylindrical insertion holes 112, and the other end of the base shell 110 has an opening 1111 communicating with the mounting cavity 111. The base shell 110 has at least one mounting portion 113 at the opening 1111. The mounting portion 113 has threaded fastener through holes 1131, and all the threaded fastener through holes 1131 correspond one-to-one with all the cylindrical insertion holes 112. The clutch assembly 120 is mounted in the mounting cavity 111. The inner wall of the threaded fastener through hole 1131 has threads for screwing with threaded fasteners, or the mounting portion 113 has a threaded hole on one side of the threaded fastener through hole 1131, and the inner wall of the threaded hole has threads for screwing with threaded fasteners. Reference Figure 1 and Figure 2 In the clutch device provided by this utility model, the cylindrical insertion hole 112 on the bottom shell 110 can be used for the insertion of the positioning pin 410 on the front panel shell 400, and the threaded fastener through hole 1131 on the mounting part 113 can be used for the installation of threaded fasteners screwed to the positioning pin 410, thereby meeting the requirements for proper installation. Secondly, referring to... Figure 3 and Figure 4 The threaded fastener through hole 1131 or threaded hole on the mounting part 113 can be directly screwed to the threaded fastener installed on the back shell 200 of the panel, thereby meeting the reverse installation requirements. At the same time, since the mounting part 113 of the bottom shell 110 is directly fixed to the panel by the threaded fastener, it can also ensure that the bottom shell 110 is firmly fixed when reversed.

[0026] In the specific implementation process, when the inner wall of the threaded fastener through hole 1131 is threaded, the threaded fastener installed on the back cover housing 200 of the panel can be screwed into the threaded fastener through hole 1131, thereby eliminating the need for setting the threaded hole; of course, when the mounting part 113 is provided with a threaded hole, the threaded fastener installed on the back cover housing 200 of the panel can also be screwed into the threaded hole.

[0027] Furthermore, the clutch device provided by this utility model can ensure that the bottom shell 110 is securely fixed, whether it is installed on the front shell 400 of the panel or the back shell 200 of the panel. Based on this, the clutch device does not need to be provided with a cover plate for closing the opening 1111, so as to reduce the number of parts and reduce costs.

[0028] Of course, in other embodiments, the clutch device may also be provided with a cover plate, which closes the opening 1111. In specific implementation, the cover plate may be disposed between the mounting portions 113 and the cover plate may be connected and fixed to the bottom shell 110; or, the cover plate may be simultaneously placed on the mounting portion 113, and the cover plate may be provided with through holes corresponding to the threaded fastener through holes 1131 or threaded holes. Thus, when the clutch device is installed on the front shell 400 of the panel, the threaded fastener may pass through the through holes and threaded fastener through holes 1131 on the cover plate and then be screwed to the positioning post 410, thereby fixing the cover plate and the bottom shell 110 to the front shell 400 of the panel. When the clutch device is installed on the back shell 200 of the panel, the first threaded fastener 300 on the back shell 200 may pass through the through holes on the cover plate and then be screwed to the mounting portion 113, thereby fixing the cover plate and the bottom shell 110 to the back shell 200 at the same time.

[0029] In practical implementation, the clutch device is equipped with an electric drive device (not shown in the figure). The electric drive device is used to operate the clutch assembly 120 to close and open, thereby controlling the on and off transmission between the handle 600 and the lock body. The electric drive device can be built into the mounting cavity 111 of the bottom shell 110, or it can be placed outside the bottom shell 110.

[0030] Reference Figure 1 and Figure 5 According to some embodiments of this utility model, four mounting portions 113 are arranged in a rectangular shape, and each mounting portion 113 is provided with a threaded fastener through hole 1131. The threaded fastener through hole 1131 has threads, and four cylindrical insertion holes 112 are provided. With the above arrangement, there are four connection positions between the clutch device and the front shell 400 or the back shell 200 of the panel to ensure that the clutch device is firmly installed.

[0031] It is conceivable that in some other embodiments, only one mounting part 113 may be provided. In this case, the mounting part 113 is arranged in a ring around the opening 1111, and four threaded fastener through holes 1131 may be provided on the mounting part 113 at the same time.

[0032] It should be noted that, in the specific implementation process, the above-mentioned threaded fastener through hole 1131 and cylindrical part insertion hole 112 can also be provided in only 2, 3 or more, and the clutch device can also meet the usage requirements.

[0033] Reference Figure 5 and Figure 6According to some embodiments of the present invention, the outer contour of the bottom shell 110 is rectangular, and the four mounting parts 113 are arranged one-to-one at the four corners of the bottom shell 110. In this way, the occupation of the cylindrical insertion hole 112 and the mounting part 113 on the internal space of the mounting cavity 111 can be minimized.

[0034] Reference Figure 3 and Figure 5 According to some embodiments of this utility model, the side of the mounting part 113 facing away from the cylindrical insertion hole 112 is a first support surface 1132, which is used to abut against the back shell 200 of the panel. Therefore, when the clutch device is installed on the back shell 200 of the panel, the first support surface 1132 on the mounting part 113 can fit together with the back shell 200 of the panel, ensuring that the bottom shell 110 is firmly installed.

[0035] Reference Figure 1 and Figure 6 According to some embodiments of this utility model, the bottom shell 110 has a second support surface 114 on the side opposite to the mounting portion 113, and the second support surface 114 is used to abut against the back shell 200 of the panel. Therefore, when the clutch device is installed on the back shell 200 of the panel, the second support surface 114 on the mounting portion 113 can fit together with the back shell 200 of the panel, ensuring that the bottom shell 110 is firmly installed.

[0036] Reference Figure 6 According to some embodiments of the present invention, the side wall of the cylindrical insertion hole 112 has an arc-shaped positioning surface 1121. The arc-shaped positioning surface 1121 is used to abut and fit against the positioning post 410 on the front shell 400 of the panel. Thus, when the clutch device is installed on the front shell 400 of the panel, the bottom shell 110 can be positioned by utilizing the cooperation between the positioning post 410 and the arc-shaped positioning surface 1121.

[0037] According to some other embodiments of the present invention, the clutch device may also include a cover plate (not shown in the figure), which is connected and fixed to the bottom shell 110 and closes the opening 1111.

[0038] Reference Figure 3 and Figure 4 According to a second aspect of the present invention, the smart lock includes a panel and the aforementioned reversible clutch device. The back cover 200 of the panel is provided with at least two screw mounting holes 210. All screw mounting holes 210 correspond one-to-one with all threaded fastener through holes 1131 or all threaded holes. A first threaded fastener 300 is installed in the screw mounting hole 210. The first threaded fastener 300 is screwed into the corresponding threaded fastener through hole 1131 or threaded hole.

[0039] In the specific implementation process, when the panel is provided with a back shell 200, the panel also has a front shell 400. The front shell 400 and the back shell 200 enclose a closed cavity to protect the clutch device and other components inside the panel. The handle 600 passes through the front shell 400 and is then connected to the clutch assembly 120 of the clutch device.

[0040] The clutch device provided by this utility model allows the threaded fastener through hole 1131 or threaded hole on the mounting part 113 to be directly screwed into the first threaded fastener 300 installed in the screw mounting hole 210 on the back shell 200, thereby satisfying the reverse installation requirement. At the same time, since the mounting part 113 of the bottom shell 110 is directly fixed to the back shell 200 of the panel through the first threaded fastener 300, it can also ensure that the bottom shell 110 is firmly fixed when reversed.

[0041] Reference Figure 1 and Figure 2 According to the third aspect of the present invention, the smart lock includes a panel and the aforementioned reversible clutch device. The front shell 400 of the panel is provided with at least two positioning posts 410. All positioning posts 410 are inserted into all cylindrical insertion holes 112 in a corresponding manner. A second threaded fastener 500 is installed in the threaded fastener through hole 1131. The second threaded fastener 500 is screwed to the corresponding positioning post 410.

[0042] In practical implementation, when the clutch device is installed in a front-mounted manner on the panel, the back cover 200 is not required. When the panel is installed on the door, the clutch device and the second threaded fastener 500 are both concealed between the door and the front cover 400, achieving an anti-theft function. The handle 600 rotatably passes through the front cover 400 and connects to the clutch assembly 120 of the clutch device.

[0043] The clutch device provided by this utility model has a cylindrical insertion hole 112 on the bottom shell 110 for inserting the positioning pin 410 on the front shell 400, and a threaded fastener through hole 1131 on the mounting part 113 for installing the second threaded fastener 500 screwed to the positioning pin 410, thereby meeting the requirements for proper installation.

[0044] In practice, the second threaded fastener 500 and the first threaded fastener 300 can be either screws or bolts.

[0045] In practice, the panel installed on the side of the door closer to the outside is called the front panel, and the panel installed on the side of the door closer to the inside is called the rear panel. Smart locks usually have at least one of the front panel and the rear panel.

[0046] Typically, the clutch mechanism is installed in the front panel using a forward mounting method, while it is installed in the rear panel using a reverse mounting method. However, for different models of smart locks, some smart locks use a reverse mounting method for the front panel and a forward mounting method for the rear panel, some smart locks use a forward mounting method for both the front and rear panels, or some smart locks use a reverse mounting method for both the front and rear panels.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
