[0054] Please also refer to Figures 1 to 3 . Figure 1 This is a schematic diagram of the electronic lock of this utility model. Figure 2This is an exploded view of the outer assembly of the electronic lock of this utility model. Figure 3 This is an exploded view of the outer assembly of the electronic lock of this utility model from another perspective. As shown, the electronic lock 10 of this utility model includes an outer assembly 100, an inner assembly 200, and a latch assembly 300. The outer assembly 100 is disposed on the outer side of a door panel 20. The outer assembly 100 includes a housing 110, an input module 120, a lock assembly 130, and a sleeve 140. The inner assembly 200 is disposed on the inner side of the door panel 20 and is electrically connected to the outer assembly 100 of the electronic lock 10. The inner assembly 200 of the electronic lock may include a control circuit for controlling the operation of the electronic lock 10, and an internal power supply for providing the power required for the operation of the electronic lock, but this utility model is not limited thereto. The latch assembly 300 is connected between the outer assembly 100 and the inner assembly 200. The latch assembly 300 includes a latch housing 310 and a latch 320. The latch housing 310 is fixed to the door panel 20. The latch 320 is movably mounted on the latch housing 310.

[0055] Input module 120 is disposed on housing 110 for receiving user input. In this embodiment of the invention, input module 120 is provided with multiple buttons 122. Each button 122 is marked with a corresponding button character. The button character marked on button 122 can be Arabic numerals or graphic symbols, but the invention is not limited thereto. On the other hand, input module 120 is also provided with multiple button circuits (not shown) corresponding to the multiple buttons 122 respectively. Each button circuit is used to generate a button signal when a corresponding button 122 is pressed. When the button signal generated by input module 120 corresponds to or matches the authentication data pre-stored by the control circuit of inner assembly 200, the control circuit can control electronic lock 10 to perform a predetermined operation, such as unlocking or locking. For example, when the control circuit controls electronic lock 10 to perform locking operation, latch 320 of latch assembly 300 will extend outward; when the control circuit controls electronic lock 10 to perform unlocking operation, latch 320 of latch assembly 300 will retract inward.

[0056] The lock assembly 130 includes a lock housing 132, a lock cylinder assembly 134, and a drive plate 137. The lock housing 132 is fixed to the housing 110. For example, the housing 110 has a fixing portion 111 and a through hole H, through which the lock housing 132 passes to be locked to the fixing portion 111 of the housing 110 by a screw S1. In this embodiment of the invention, the fixing portion 111 extends inward from the hole wall W of the through hole H, but the invention is not limited thereto. The lock cylinder assembly 134 is disposed within the lock housing 132. The drive plate 137 is connected to the lock core 135 of the lock cylinder assembly 134 to rotate with the lock core 135 of the lock cylinder assembly 134, and the drive plate 137 passes through the through hole H to be connected to the latch assembly 300. A keyhole 136 is formed on the lock core 135 of the lock cylinder assembly 134 to receive a key for an unlocking operation or a locking operation. For example, when the electronic lock 10 fails or loses power, the user can insert a key into the keyhole 136 and turn the key so that the lock core 135 drives the latch 320 of the latch assembly 300 to extend outward or retract inward via the drive plate 137.

[0057] The sleeve 140 is fitted onto the lock housing 132. The sleeve 140 has a first positioning structure 142, while the housing 110 has a second positioning structure 112. The second positioning structure 112 of the housing 110 is used to engage with the first positioning structure 142 of the sleeve 140 to prevent the sleeve 140 from rotating relative to the housing 110. In this embodiment, the first positioning structure 142 is a groove, and the second positioning structure 112 is a protrusion, but this is not a limitation of the present invention. On the other hand, when the lock housing 132 is fixed to the housing 110, the flange 133 of the lock housing 132 abuts against the sleeve 140 to clamp the sleeve 140 between the lock housing 132 and the housing 110 (please refer to both). Figure 4 and Figure 5 In this embodiment of the invention, the sleeve 140 may be made of a metal material and may have a knurled surface, but the invention is not limited thereto.

[0058] Based on the above configuration, the appearance design of the sleeve 140 of this utility model is not limited by the lock assembly 130, and different processing steps (e.g., knurling, surface treatment, etc.) can be performed on the sleeve 140 and the housing 110, thereby increasing the design flexibility of the outer assembly 100 of the electronic lock 10 of this utility model in terms of appearance. Taking this embodiment as an example, the sleeve 140 has a first ring portion 144 with a larger outer diameter and a second ring portion 146 with a smaller outer diameter. The surface of the first ring portion 144 of the sleeve 140 can be knurled or otherwise surface treated. Furthermore, the housing 110 has an annular protrusion 113 that protrudes relative to the hole wall W of the through hole H, so that the inner diameter of the annular protrusion 113 corresponds to (or is equal to) the outer diameter of the second ring portion 146. The second ring portion 146 of the sleeve 140 is used to insert into the through hole H to abut against the annular protrusion 113 of the housing 110. When the lock housing 132 is fixed to the housing 110, the edge of the first ring portion 144 of the sleeve 140 can be substantially flush with the housing 110 (e.g., Figure 1 As shown), so that the knurled surface (or other machined surface) on the first ring portion 144 and the outer surface of the housing 110 form a special shape combination. If the sleeve 140 and the housing 110 are integrally manufactured, it is difficult to perform knurling on the sleeve 140 without affecting the adjacent parts of the housing 110.

[0059] Please refer to Figure 4 and refer to them together. Figures 1 to 3 . Figure 4 This is a cross-sectional view of the electronic lock of this utility model installed on a door panel 20. As shown, a supporting protrusion 114 is formed on the rear side of the housing 110. When the outer assembly 100 of the electronic lock 10 is installed on the outer side of the door panel 20, the supporting protrusion 114 extends into the mounting hole 22 of the door panel 20 to support the housing 110, thereby increasing the stability of the outer assembly 100 when installed on the door panel 20. In this embodiment of the utility model, the housing 110 and the supporting protrusion 114 are integrally formed. Figure 4 In the middle, the mounting hole 22 of the door panel 20 has a first predetermined diameter D1.

[0060] Based on the above configuration, since the housing 110 and the supporting protruding wall 114 are integrally formed, the outer assembly 100 of the electronic lock 10 of this utility model can be stably installed to the door panel 20 without additional installation components, thereby increasing the convenience of installing the outer assembly 100 to the door panel 20.

[0061] Please refer to Figure 5 and refer to them together. Figures 1 to 3 . Figure 5This is a cross-sectional view of the electronic lock of this utility model installed on another door panel 20'. As shown in the figure, the outer assembly 100 of the electronic lock 10 of this utility model further includes an auxiliary mounting member 150 for fixing to the rear side of the housing 110. In this embodiment, the auxiliary mounting member 150 is fixed to the rear side of the housing 110 by screws S2 (such as screws S2). Figure 3 (As shown) It is detachably fixed to the rear side of the lock housing 110, but the fixing method of the auxiliary mounting member 150 is not limited to this. When the outer assembly 100 of the electronic lock 10 is installed on the outer side of the door panel 20', the auxiliary mounting member 150 is used to extend into the mounting hole 22' of the door panel 20' to support the housing 110, thereby increasing the stability of the outer assembly 100 when installed on the door panel 20'. Figure 4 In the present invention, the mounting hole 22' of the door panel 20' has a second predetermined diameter D2, and the second predetermined diameter D2 is different from the first predetermined diameter D1. In this embodiment of the present invention, the second predetermined diameter D2 is larger than the first predetermined diameter D1.

[0062] Based on the above configuration, when the outer assembly 100 of the electronic lock 10 of this utility model is to be installed onto the door panel 20' with a mounting hole 22' of a larger diameter, the auxiliary mounting component 150 can be fixed to the rear side of the housing 110 first to increase the stability of the outer assembly 100 when installed onto the door panel 20'. Therefore, the outer assembly 100 of the electronic lock 10 of this utility model can selectively use the auxiliary mounting component according to the mounting hole size of the door panel.

[0063] In addition, the electronic lock 10 of this utility model includes a waterproof gasket 160, which is disposed on the housing 110. The waterproof gasket 160 is used to cover the rear side of the housing 110 to prevent water from entering the rear side of the electronic lock 100.

[0064] On the other hand, in other embodiments of this invention, the input module 120 can receive user input in other ways. For example, the input module can be a touch module to receive user touch input; or the input module can be a wireless input module (Bluetooth module or near-field communication module, etc.) to receive user wireless signal input.

[0065] Compared to prior art, conventional electronic locks can only use a plastic injection-molded shell to cover the lock assembly, thus limiting the appearance design of the outer assembly of conventional electronic locks. The outer assembly 100 of this electronic lock utilizes a sleeve 140 to cover the lock assembly 130, and the appearance of the sleeve 140 is not limited by the lock assembly 130, thereby increasing the design flexibility of the outer assembly 100 of this electronic lock 10. Furthermore, the outer assembly 100 of this electronic lock 10 can be installed onto a door panel with mounting holes of different diameters using a supporting protrusion 114 or an auxiliary mounting component 150, increasing the convenience of installing the outer assembly 100 onto the door panel.

[0066] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
