[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the smart lock includes a housing 1 and a cover plate assembly 2. The housing 1 has a panel 11 on one side and a mounting groove 12. The opening of the mounting groove 12 is located on the panel 11. The keyhole end of the lock cylinder and the doorbell button 4 are disposed within the mounting groove 12. The cover plate assembly 2 is detachably disposed within the mounting groove 12 to seal the opening of the mounting groove 12. A trigger part 211 is provided on the cover plate assembly 2 at a position opposite to the doorbell button 4 to trigger the doorbell button 4 when the cover plate assembly 2 is pressed.

[0027] Specifically, such as Figure 2 As shown, the housing 1 has a mounting groove 12. The housing 1 can be integrally formed to form the mounting groove 12, or the housing 1 can consist of multiple parts, which together enclose the mounting groove 12. The specific formation method of the mounting groove 12 can be set according to actual needs and is not limited here.

[0028] It should be noted that the bottom wall of the mounting groove 12 faces the opening of the mounting groove 12. A first clearance hole is provided on the bottom wall of the mounting groove 12, and the keyhole end of the lock cylinder passes through the first clearance hole and extends into the mounting groove 12, with the keyhole 3 facing the opening of the mounting groove 12 so as to unlock with a key.

[0029] A second clearance hole is also provided on the bottom wall of the mounting groove 12. The doorbell button 4 is located at the second clearance hole and is at least partially located within the mounting groove 12. The rebound direction of the doorbell button 4 faces the opening of the mounting groove 12.

[0030] In this embodiment, both the keyhole end of the lock cylinder and the doorbell button 4 are located within the mounting groove 12. The opening of the mounting groove 12 is closed by the cover plate assembly 2, allowing the keyhole 3 and the doorbell button 4 to share the cover plate assembly 2. The cover plate assembly 2 seals the mounting groove 12, reducing the entry of external dust into the keyhole 3. Furthermore, concealing the keyhole 3 within the mounting groove 12 enhances the overall aesthetics. Pressing the cover plate assembly 2 also triggers the doorbell button 4. The cover plate assembly 2 is easy to identify and operate, improving the user experience. When unlocking with a key is required, the cover plate assembly 2 can be removed from the mounting groove 12. The shared cover plate assembly 2 for the doorbell button 4 and keyhole 3 saves space on the panel 11, resulting in a simpler and more aesthetically pleasing layout, further improving the user experience.

[0031] In this embodiment, the cover plate assembly 2 is inserted into the mounting slot 12.

[0032] Specifically, the dimensions of the mounting groove 12 are matched with the outer contour dimensions of the cover assembly 2, so that the cover assembly 2 can close the opening of the mounting groove 12, while triggering the doorbell button 4 when the cover assembly 2 is pressed.

[0033] Understandably, the cover plate assembly 2 is installed in the mounting slot 12 by plugging in, without the need for fasteners. This facilitates the installation and removal of the cover plate assembly 2, while also simplifying the overall structure and improving aesthetics.

[0034] In this embodiment, as Figures 2 to 5 As shown, the cover assembly 2 includes an inner cover 21 and an outer cover 22. The inner cover 21 is elastic, and a trigger part 211 is disposed on the inner cover 21. The outer cover 22 is connected to the inner cover 21, and the outer cover 22 faces the outside of the mounting groove 12.

[0035] The inner cover 21 is elastic. For example, the inner cover 21 can be made of rubber, silicone, etc.

[0036] like Figure 3 and Figure 4As shown, a trigger portion 211 is disposed on the inner cover 21, and the trigger portion 211 can be a boss protruding from the inner cover 21. The trigger portion 211 can be separately formed from the inner cover 21, or it can be integrally formed with the inner cover 21. When the trigger portion 211 is integrally formed with the inner cover 21, the reliability of the connection between the trigger portion 211 and the inner cover 21 can be improved, and the assembly process can be simplified.

[0037] In this embodiment, the cover assembly 2 includes an inner cover 21 and an outer cover 22. The inner cover 21 is elastic. When the outer cover is pressed, the outer cover 22 squeezes the inner cover 21, causing the inner cover 21 to press the doorbell button via the trigger part 211. When the outer cover 22 is released, the inner cover 21 resets and simultaneously drives the outer cover 22 to reset. The outer cover 22 can protect the inner cover 21 and improve its service life. The outer cover 22 can be made of the same material as the panel 11 to improve overall uniformity.

[0038] In this embodiment, as Figure 4 As shown, the inner cover 21 has a spring-loaded part 212 on its bottom wall facing the mounting groove 12 so that the cover assembly 2 can be driven to reset by the spring-loaded part 212 when the cover assembly 2 is released.

[0039] Multiple spring-loaded portions 212 can be provided, and the multiple spring-loaded portions 212 are spaced apart on the inner cover 21. For example, two spring-loaded portions 212 are provided, and the two spring-loaded portions 212 are disposed opposite to each other on the inner cover 21. By providing multiple spring-loaded portions 212, it is beneficial to improve the overall elasticity, so as to improve the sensitivity of pressing the doorbell button 4 on the outer shell 1.

[0040] Specifically, the spring-loaded part 212 includes a spring-loaded seat and a spring-loaded post. The spring-loaded seat is disposed on the inner cover 21, and the spring-loaded post is disposed on the side of the spring-loaded seat opposite to the inner cover 21. Multiple spring-loaded posts can be provided, spaced apart on the spring-loaded seat. By providing multiple spring-loaded posts, the overall stability is improved, and the elasticity of the spring-loaded part 212 is also enhanced. The spring-loaded seat and the spring-loaded post can be integrally formed with the spring-loaded seat. This integral forming method improves the overall connection strength and facilitates processing.

[0041] It is understandable that a spring-loaded part 212 is provided on the inner cover 21. When the inner cover 21 is pressed, the spring-loaded part 212 is easily compressed, which makes it easier for the trigger part 211 to press the doorbell button 4. When the pressure on the inner cover 21 is released, the spring-loaded part 212 can push the inner cover 21 to reset, which helps to ensure that the inner cover 21 can be reliably reset.

[0042] In this embodiment, as Figure 2 , Figure 4 and Figure 5As shown, the cover plate assembly 2 also includes a fixing rod 23, which is connected to the inner cover body 21. The fixing rod 23 has an elastic snap-fit ​​part 231 in the middle. The bottom wall of the mounting groove 12 is provided with a mounting hole 13 corresponding to the position of the fixing rod 23. The fixing rod 23 passes through the mounting hole 13, and the elastic snap-fit ​​part 231 snaps onto the bottom wall of the mounting groove 12 on the side away from the inner cover body 21.

[0043] The fixing rod 23 can be a silicone fixing rod 23 or a rubber fixing rod 23, giving the fixing rod 23 a certain degree of elasticity to facilitate the installation and removal of the fixing rod 23. The fixing rod 23 is connected to the inner cover 21. Exemplarily, the fixing rod 23 can be integrally formed with the inner cover 21 to improve the reliability of the connection between the fixing rod 23 and the inner cover 21.

[0044] The elastic locking part 231 is provided on the fixing rod 23. The elastic locking part 231 can be integrally formed with the fixing rod 23 to facilitate the processing of the elastic locking part 231 and save assembly steps. In the axial direction of the fixing rod 23, the cross-section of the elastic locking part 231 gradually increases from the end away from the inner cover 21 to the end closer to the inner cover 21, so as to facilitate the elastic locking part 231 passing through the mounting hole 13 and make it difficult for the elastic locking part 231 to disengage from the mounting hole 13 on the side of the bottom wall of the mounting groove 12 away from the inner cover 21.

[0045] In this embodiment, by providing a fixing rod 23 on the inner cover 21 and an elastic snap-fit ​​part 231 on the fixing rod 23, when installing the cover assembly 2, the fixing rod 23 passes through the mounting hole 13. By pulling the fixing rod 23, the elastic snap-fit ​​part 231 on the fixing rod 23 passes through the mounting hole 13 and abuts against the bottom wall of the mounting groove 12 on the side away from the inner cover 21. This makes it difficult for the fixing rod 23 to come out of the mounting hole 13, thus improving the reliability of the connection of the cover assembly 2.

[0046] In this embodiment, as Figure 2 and Figure 4 As shown, the fixing rod 23 is located on both sides of the elastic snap-fit ​​part 231 as the first connecting section 233 and the second connecting section 232, respectively. The diameter of the second connecting section 232 is smaller than the diameter of the mounting hole 13, and the second connecting section 232 is far away from the inner cover 21.

[0047] It is understandable that setting the diameter of the second connecting segment 232 to the diameter of the connecting hole allows the second connecting segment 232 to be quickly passed through the connecting hole when installing the fixing rod 23, which helps to improve the installation efficiency of the fixing rod 23.

[0048] In this embodiment, as Figure 3 and Figure 4As shown, the outer cover 22 is provided with a first groove 221 facing the inner cover 21, and the inner cover 21 is inserted into the first groove 221.

[0049] It is understandable that by providing a first groove 221 on the outer cover 22 and inserting the inner cover 21 into the first groove 221, the connection between the inner cover 21 and the outer cover 22 can be facilitated. No other connecting parts are needed between the inner cover 21 and the outer cover 22, making the overall structure more compact.

[0050] In this embodiment, as Figures 3 to 5 As shown, the cover assembly 2 also includes a first magnetic element 24, which is disposed between the inner cover 21 and the outer cover 22. A second magnetic element (not shown in the figure) is disposed inside the housing 1. The first magnetic element 24 and the second magnetic element are magnetically attracted to each other.

[0051] A second magnetic component is provided inside the housing 1. The specific installation position of the second magnetic component is not limited here, as long as it can attract each other with the first magnetic component 24.

[0052] For example, the first magnetic element 24 can be a metal sheet, and the second magnetic element can be a magnet.

[0053] Weight reduction holes can be provided on the first magnetic component 24. Multiple weight reduction holes can be provided at intervals. By providing weight reduction holes, the weight of the first magnetic component 24 can be reduced, thereby reducing the overall weight of the cover plate assembly 2.

[0054] In this embodiment, the first magnetic element 24 is disposed between the inner cover 21 and the outer cover 22. The inner cover 21 and the outer cover 22 are connected, so that the inner cover 21, the outer cover 22 and the first magnetic element 24 can form a whole. At the same time, through the mutual attraction between the first magnetic element 24 and the second magnetic element in the housing 1, the cover plate assembly 2 can be reliably fixed in the mounting groove 12.

[0055] In this embodiment, as Figure 3 and Figure 5 As shown, the inner cover 21 has a second groove 213 on the side facing the first magnetic component 24. The first magnetic component 24 is disposed in the second groove 213, and the inner cover 21 has a connecting post 214 facing the first magnetic component 24. The first magnetic component 24 has a plug hole corresponding to the position of the connecting post 214, and the connecting post 214 passes through the plug hole.

[0056] For example, there may be two connecting posts 214, and two fixing holes 241 are provided on the corresponding first magnetic element 24. The two connecting posts 214 and the two fixing holes 241 are connected one-to-one.

[0057] It is understandable that by placing the first magnetic element 24 in the second groove 213, the first magnetic element 24 can be limited, and by cooperating with the connecting post 214 and the fixing hole 241 of the first magnetic element, the first magnetic element 24 can be connected to the inner cover 21, so that the first magnetic element 24 can be stably fixed on the inner cover 21.

[0058] In this embodiment, as Figure 2 and Figure 3 As shown, the smart lock also includes a light source 5 and a light guide 6. The light source 5 is disposed in the mounting groove 12. The cover plate assembly 2 has a display area (not shown in the figure). The light guide 6 is disposed between the light source 5 and the display area. The light source 5 is used to emit light towards the light guide 6 to illuminate the display area through the light guide 6.

[0059] The light source 5 can be an LED lamp, and a circuit board 7 is provided inside the housing 1. The LED lamp is electrically connected to the circuit board 7. The light source 5 can be set as a ring, and the light source 5 is set at the bottom circumferential direction of the mounting groove 12.

[0060] For example, the shape of the display area can be the doorbell button 4 marking. Specifically, the display area can be set on the outer cover 22, which is made of a light-transmitting material. A light-shielding material is coated on the outer cover 22, and the light-shielding material avoids the doorbell button 4 marking part. When the light source 5 is lit, the doorbell button 4 marking part can be lit.

[0061] like Figure 3 As shown, the light guide 6 is disposed circumferentially in the mounting groove 12 and is positioned opposite to the light source 5. The outer cover 22 has a light guide ring 222 circumferentially on its edge. The light guide ring 222 and the outer cover 22 are integrally formed, and the light guide ring 222 and the light guide 6 are positioned opposite to each other. When the light source 5 emits light to the light guide 6, the light guide 6 transmits the light to the display area through the light guide ring 222.

[0062] In this embodiment, a light source 5 and a light guide 6 are set in the mounting groove 12, and a display area is set on the cover plate assembly 2. The light guide 6 is set between the light source 5 and the display area. After the light source 5 emits light, the light can be transmitted to the display area through the light guide 6, thereby illuminating the display area and realizing the light prompt of the doorbell button 4, which is beneficial to improving the user experience.

[0063] In this embodiment, the smart lock also includes a control unit (not shown in the figure). The light source 5 is electrically connected to the control unit. The control unit is used to receive a trigger signal and control the light source 5 to turn on or off according to the trigger signal.

[0064] Specifically, the trigger signal is divided into an on trigger signal and an off trigger signal. When the trigger signal is an on trigger signal, the control unit controls the light source 5 to turn on; when the trigger signal is an off trigger signal, the control unit controls the light source 5 to turn off. The method by which the control unit controls the light source 5 to turn on or off by receiving the trigger signal is a conventional existing technology, and its specific setting and working principle will not be described in detail here.

[0065] For example, the activation trigger signal can be the visitor signal detected by the infrared sensor 8. Specifically, such as... Figure 3 As shown, an infrared sensor 8 can be installed on the corresponding panel 11 of the housing. The infrared sensor 8 detects the presence of visitors. When the infrared sensor 8 detects a visitor, it sends a visitor signal to the control unit, which then controls the light source 5 to turn on. The activation trigger signal can also be a detected numeric keypad touch operation, NFC card operation, palm vein recognition operation, or fingerprint recognition operation. The deactivation trigger signal can be a password, NFC card, palm vein recognition, or fingerprint recognition successful verification signal.

[0066] It can be understood that the control unit in this embodiment controls the light source 5 to turn on or off according to the received trigger signal, which improves the intelligence of the control of the light source 5. Furthermore, it can light up or turn off the button indicators as needed, which can not only improve the user experience but also save power resources.

[0067] The door in this embodiment includes the smart lock described above.
