[0081] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0082] It should be understood that the terms "device" and / or "module" as used herein are one method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0083] Unless the context clearly indicates an exception, words such as "a," "an," "a kind," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0084] With the rapid development of biometric technology, palm recognition has gained increasing attention as an emerging method of identity verification. However, existing palm recognition door lock designs are ill-suited for all users, resulting in limited recognition range, reduced accuracy, and a poor user experience.

[0085] To address these issues, a smart lock and door are needed to improve recognition accuracy and optimize user experience.

[0086] To make palm biometric technology applicable to more users and improve its accuracy and practicality, some embodiments of this application provide a smart door lock that can adjust the optical axis angle of the recognition camera as needed, thereby improving recognition accuracy and enhancing user experience.

[0087] Figure 1 is an exemplary side view of a smart door lock according to some embodiments of this application.

[0088] In some embodiments, the smart lock 100 may include a lock body 110, which includes a palm biometric module 120 and a bracket 130.

[0089] The door lock body 110 refers to the structure used to achieve locking and unlocking.

[0090] In some embodiments, the door lock body 110 further includes a locking structure (not shown in the figure) for achieving locking, such as a bolt, an electromagnetic lock, etc. In some embodiments, the door lock body 110 may include an unlocking control mechanism (not shown in the figure). The unlocking control mechanism is used to control the locking structure of the door lock body 110 to unlock. For example, the unlocking control mechanism can control the bolt to retract. As another example, the unlocking control mechanism can control the electromagnet of the electromagnetic lock to demagnetize.

[0091] In some embodiments, a second panel 160 for inputting a password may also be provided on the door lock body 110. Further details regarding the second panel 160 are provided in the following description.

[0092] The palm biometric module 120 refers to a module that uses palm biometrics to control the unlocking of door locks. In some embodiments, palm biometrics may refer to palm vein recognition. Palm vein recognition is a biometric technology that uses the uniqueness of palm veins for identification. Its main principle is to utilize the absorption characteristics of deoxyhemoglobin in veins to 760nm near-infrared light, obtain vein information by scanning the palm, and compare it with pre-stored vein information to achieve identification.

[0093] Figure 2 is an exemplary schematic diagram of the tilt angle of a palm biometric module and the optical axis angle of a recognition camera according to some embodiments of this application.

[0094] In some embodiments, as shown in FIG2, the length direction of the side of the palm biometric module 120 is denoted as M, and the direction M has an angle α with the vertical direction Y.

[0095] In some embodiments, as shown in FIG2, a recognition camera 121 is provided on the palm biometric module 120, and the palm biometric module 120 is signal-connected to the unlocking control mechanism; when the recognition camera 121 is working, the optical axis N of the recognition camera 121 forms an angle b with the vertical direction Y. In some embodiments, the recognition camera 121 is used to scan the palm to obtain palm vein images, and then obtain vein information. When the recognition camera 121 is working, it refers to the state when the recognition camera 121 is scanning the palm.

[0096] In some embodiments, when the recognition camera 121 is not working, the optical axis N of the recognition camera 121 can form an angle b with the vertical direction Y. This angle can be acute, right, obtuse, etc., and can be set according to actual needs.

[0097] In some embodiments, the tilt angle α of direction M relative to the vertical direction Y can be preset to 60°, and correspondingly, the angle b between the recognition camera 121 and the vertical direction can be preset to 30°. The tilt angle α or the angle b can be determined based on the natural outstretched angle of an adult's hand. In some embodiments, when the recognition camera 121 is working, the angle b formed by the optical axis N of the recognition camera 121 and the vertical direction Y is an acute angle, and the angle b can be adjustable or fixed. See the related description below for further details.

[0098] In some embodiments, the identification camera 121 may be an infrared camera.

[0099] The bracket 130 refers to the structure used to support and install the various components on the door lock body 110.

[0100] In some embodiments, as shown in FIG1, the palm biometric module 120 is mounted on the upper part of the door lock body 110 via a bracket 130. For example, the palm biometric module 120 can be positioned in the middle or near the top of the upper part of the door lock body 110, depending on actual usage requirements. By mounting the palm biometric module 120 on the upper part of the door lock body 110, users are less likely to accidentally touch the door lock panel (e.g., the second panel) when performing palm biometric recognition, and the scanning and recognition range of the recognition camera 121 can also be increased.

[0101] In some embodiments, the tilt angle α of the orientation M of the palm biometric module 120 can be determined by the shape and installation angle of the bracket 130. In some embodiments, the bracket 130 can be rotated to adjust the tilt angle α of the orientation M of the palm biometric module 120, as described in Figures 3 and 4 below for further details.

[0102] In some embodiments, as shown in FIG1, the bracket 130 includes a first mounting bracket 131. The first mounting bracket 131 is a mounting bracket for mounting the palm biometric module 120. In some embodiments, the palm biometric module 120 is mounted on the mounting surface of the first mounting bracket 131, and the mounting surface is inclined relative to the vertical direction. The mounting surface of the first mounting bracket 131 can be the inner side surface of the first mounting bracket 131. In some embodiments, the inclination angle of the mounting surface relative to the vertical direction can be consistent with the inclination angle α of the palm biometric module 120. When a user extends their palm for recognition, it is usually tilted at a certain angle. In some embodiments, the aforementioned inclination angle α and the included angle β can be fixed and can be preset according to actual needs. For example, the inclination angle α of direction M relative to the vertical direction Y can be set to 60°, and the included angle β of the recognition camera 121 with the vertical direction can be set to 30°.

[0103] By setting up a bracket including a first mounting frame, the palm biometric module is mounted on the mounting surface of the first mounting frame, and the recognition camera is fixed at a reasonable tilt angle. This makes the recognition range of the recognition camera more in line with the user's palm-out habits, thereby improving recognition speed and efficiency. At the same time, this setting helps to make the installation of the palm biometric module more convenient and reduces wear caused by frequent rotation of the recognition camera. This can improve recognition accuracy and user experience while extending the product's lifespan.

[0104] In some embodiments, as shown in FIG1, the bracket 130 may further include a second mounting bracket 132 connected to the first mounting bracket 131, the second mounting bracket 132 being used to mount the unlocking control mechanism.

[0105] In some embodiments, the first mounting bracket 131 is connected to the top of the second mounting bracket 132. For example, the bottom of the first mounting bracket 131 can be snapped onto the top of the second mounting bracket 132.

[0106] By setting up a second mounting bracket that connects to the first mounting bracket, it is easier to quickly install and adjust the various components on the door lock body.

[0107] In some embodiments, as shown in FIG1, the palm biometric module 120 is fixedly mounted on the mounting surface of the first mounting bracket 131 by a fastener 140. The mounting surface of the first mounting bracket 131 is provided with a through hole for the recognition camera 121 to pass through (see FIG7). For example, the fastener 140 can be a nut, which cooperates with bolts on the mounting surface of the first mounting bracket 131 to fix the palm biometric module. By setting the fastener and the through hole, it is beneficial to maintain the stability of the palm biometric module and ensure the recognition effect of the recognition camera.

[0108] In some embodiments, as shown in FIG1, the door lock body 110 is further provided with a first panel 150 and a second panel 160.

[0109] The first panel 150 refers to the panel located on the user-facing side outside the palm biometric module 120.

[0110] In some embodiments, a first panel 150 covers a first mounting bracket 131, and the first panel 150 and the palm biometric module 120 are located on opposite sides of the first mounting bracket 131.

[0111] The second panel 160 is a panel located on the outside of the door lock body 110, facing the user.

[0112] In some embodiments, the second panel 160 can be used for password input. As shown in Figures 1 and 2, in some embodiments, the second panel 160 can be parallel to the length direction of the door lock body 110. In some embodiments, the second panel 160 can be parallel to the vertical direction Y. In some embodiments, the first panel 150 is inclined relative to the second panel 160.

[0113] In some embodiments of this application, by setting a first panel and a second panel, the internal structure of the smart lock can be protected.

[0114] In some embodiments, the unlocking control mechanism determines whether to unlock based on the recognition result of palm biometrics. The recognition result can refer to whether the information acquired by the recognition camera 121 matches pre-stored information. Taking palm vein recognition as an example, the acquired vein information is matched with pre-stored vein information. If the matching degree exceeds a preset value, the recognition result is successful; if the matching degree does not exceed the preset value, the recognition result is unsuccessful; if the matching degree cannot be obtained, the recognition result is abnormal, etc. For example, when the palm biometrics recognition result is successful, the palm biometrics module 120 sends an unlocking command to the unlocking control mechanism, which then unlocks the door upon receiving the unlocking command.

[0115] In some embodiments, the smart lock 100 further includes a processing module (not shown), with the palm biometric module 120 and the unlocking control mechanism both signal-connected to the processing module. The processing module refers to a device or component that processes data and generates instructions, such as a central processing unit (CPU), a graphics processing unit (GPU), an application-specific integrated circuit (ASIC), or any combination thereof. Data may originate from the palm biometric module 120, and instructions may be sent to the unlocking control mechanism. The processing module may also include other components related to the above; for example, the processing module may also refer to a computer, mobile phone, server, circuit board with computing capabilities, etc.

[0116] In some embodiments, the processing module may include an ARM Cortex-A9 processor and 2GB DDR3 memory. In other embodiments, the processing module may also include an Intel Core i5 processor and 4GB DDR4 memory. In some embodiments, the processing module may perform tilt correction on the acquired image based on the distance information between the recognition camera 121 and the palm to eliminate the influence caused by palm tilt. In some embodiments, the processing module may perform noise reduction, enhancement, and feature extraction on the image acquired by the recognition camera 121 to improve recognition accuracy.

[0117] Figure 3 is an exemplary structural schematic diagram of a palm biometric module, support, and angle adjustment component according to some embodiments of this application; Figure 4 is an exemplary exploded view of a palm biometric module, support, and angle adjustment component according to some embodiments of this application.

[0118] In some embodiments, as shown in Figures 3 and 4, the smart door lock 100 further includes an angle adjustment component 310.

[0119] The angle adjustment component 310 is used to adjust the angle formed between the optical axis of the recognition camera 121 and the vertical direction. In some embodiments, the angle adjustment component 310 can adjust the aforementioned tilt angle a and angle b through the adjustment bracket 130.

[0120] In some embodiments, as shown in Figures 3 and 4, the angle adjustment assembly 310 includes a motor 311. For example, the motor 311 may be a micro motor, with a rated voltage of 5V and a rated speed of 300rpm.

[0121] In some embodiments, the motor 311 can drive the bracket 130 to rotate, thereby causing the recognition camera 121 to rotate. For example, the motor 311 can drive the bracket 130 to rotate, thereby causing the palm biometric module 120 to rotate, which in turn changes the angle b between the optical axis N of the recognition camera 121 and the vertical direction Y, thereby adjusting the shooting range of the recognition camera 121.

[0122] In some embodiments, the processing module can adjust the rotation angle of the motor 311 driving the bracket 130 by a preset angle based on the recognition result. For example, when recognition fails, the processing module can control the motor 311 driving the bracket 130 to rotate by a preset angle. Alternatively, the processing module can also adjust the rotation angle of the motor 311 driving the bracket 130 by receiving instruction signals from control devices (such as remote controls, mobile phones, touch controls on smart door locks, etc.).

[0123] In some embodiments, by providing the angle adjustment component 310, the support 130 can be adjusted for users of different ages, heights, or hand-out habits. Hand-out habits refer to the user's preferred posture for performing hand biometrics; for example, hand-out habits may include the angle between the palm plane and the horizontal plane.

[0124] For example, for active children, the sensitivity and adjustment range of the angle adjustment component 310 can be increased; for elderly users, the recognition time after each adjustment of the bracket 130 angle can be extended, the number of adjustments to the bracket 130 can be reduced, or the time interval between each adjustment can be extended.

[0125] For example, for taller users, the angle adjustment component 310 can adjust the bracket 130 to make the included angle b smaller, and for shorter users, the angle adjustment component 310 can adjust the bracket 130 to make the included angle b larger, so that the user can make recognition at a comfortable angle.

[0126] For example, before starting the palm scan, the recognition camera 121 can acquire an image of the user's previous action. The processing module can predict the user's palm-out habit based on the image of the previous action and adjust the support 130 accordingly. For instance, it can match the image against a historical database. If a matching palm-out habit is found, the processing module can control the angle adjustment component 310 to adjust the support 130 to the corresponding angle. If no matching palm-out habit is found, the image of the previous action is stored in the historical database, and the palm-out habit and the angle of the support 130 corresponding to subsequent successful recognition are also stored in the historical database. The matching can be based on image similarity or a machine learning algorithm.

[0127] In some embodiments, the angle adjustment component 310 can also rotate the bracket 130 by manual adjustment, as described below for further details.

[0128] In some embodiments of this application, by setting an angle adjustment component including a motor, the angle between the recognition camera and the vertical direction can be adjusted more conveniently, so as to adjust the shooting range of the recognition camera of the palm biometric module according to the usage needs, meet the usage needs of users of different ages, heights and palm placement habits, and enable the smart door lock to adapt to more users and improve the user experience.

[0129] In some embodiments of this application, by setting up a smart door lock that includes a door lock body, and the door lock body includes a palm biometric module and a bracket, the accuracy of palm biometric recognition can be improved. By keeping the optical axis of the recognition camera at a reasonable tilt angle, users can complete palm biometric recognition by placing their palms at a naturally relaxed angle, which can improve the user experience.

[0130] In some embodiments, the motor 311 is driven to the bracket 130. For example, the motor 311 may be driven to the bracket 130 via gears or via a key.

[0131] In some embodiments, as shown in Figures 3 and 4, the angle adjustment component 310 includes a rotating shaft 312, and the angle adjustment component 310 also includes a first gear 321 and a second gear 322.

[0132] The pivot 312 is the axis of rotation of the angle adjustment assembly 310. In some embodiments, the pivot 312 may be fixed, and the bracket 130 may rotate about the axis of the pivot 312.

[0133] In some embodiments, as shown in Figures 3 and 4, the motor 311 is connected to the first gear 321, the bracket 130 is connected to the second gear 322, the second gear 322 is sleeved on the outside of the rotating shaft 312, and the first gear 321 meshes with the second gear 322.

[0134] The first gear 321 and the second gear 322 cooperate to achieve power transmission. In some embodiments, different transmission ratios of the first gear and the second gear can be set according to actual needs.

[0135] In some embodiments, the first gear 321 can rotate under the drive of the motor 311, and drive the second gear 322 to rotate through gear meshing. The rotation of the second gear 322 causes the bracket 130 to rotate around the rotating shaft 312.

[0136] In some embodiments, as shown in Figures 3 and 4, the second gear 322 can be an incomplete gear, and the number of teeth of the second gear 322 can be set by technicians according to actual needs.

[0137] In some embodiments of this application, by setting a rotating shaft, a first gear, and a second gear, the tilt angle of the bracket can be adjusted more flexibly, better adapting to the usage needs of different scenarios.

[0138] In some embodiments, the angle adjustment assembly 310 includes a manual adjustment device (not shown).

[0139] For example, a rotating wheel is rotatably mounted on the door lock body 110, and a sleeve is mounted on the bracket 130 and is sleeved on the rotating shaft 312 and can rotate relative to the rotating shaft 312. The sleeve is fixed relative to the bracket 130, and the rotating wheel is connected to the sleeve in a transmission. By turning the rotating wheel, the sleeve can drive the bracket 130 to rotate relative to the rotating shaft 312.

[0140] For example, a locking device is provided on the door lock body 110. The locking device is used to lock and unlock the relative position of the door lock body 110 and the bracket 130. When the locking device is unlocked, the user can manually rotate the bracket 130 around the pivot 312. After rotating to the appropriate position, the locking device will be locked.

[0141] In some embodiments of this application, by setting a manual adjustment device, more usage scenarios can be met, and users can make personalized settings according to their own needs and flexibly adjust the tilt angle of the palm biometric module.

[0142] In some embodiments, as shown in Figures 3 and 4, the bracket 130 is provided with a mounting slot 133 for accommodating the palm biometric module 120. For example, the palm biometric module 120 can be partially embedded in the mounting slot 133 of the bracket 130, and a portion of the edge of the palm biometric module 120 can be adapted to the edge of the mounting slot 133. By providing a mounting slot on the bracket, the palm biometric module can be better installed and protected.

[0143] Figure 5 is an exemplary schematic diagram illustrating the adjustment of the angle between the optical axis of the recognition camera and the vertical direction according to some embodiments of this application.

[0144] Referring to Figure 5, in some embodiments, the angle b between the optical axis N of the recognition camera 121 and the vertical direction Y varies from 20° to 45°. In some embodiments, the angle b between the optical axis N of the recognition camera 121 and the vertical direction Y can vary from 20° to 30°. In some embodiments, the angle b between the optical axis N of the recognition camera 121 and the vertical direction Y can vary from 30° to 45°. In some embodiments, the angle b between the optical axis N of the recognition camera 121 and the vertical direction Y can be 30°, 35°, 45°, etc.

[0145] During the testing of the smart lock 100, multiple test subjects with different heights and palm extension habits were selected for comparative testing. Test results showed that when the angle b between the optical axis N of the recognition camera 121 and the vertical direction Y was used as the range of 20° to 45°, the palm vein recognition response time for different test subjects was consistently less than 1 second. Particularly noteworthy is that, within this angle range, most test subjects only needed to extend their palms naturally, without requiring deliberate posture adjustments, to achieve efficient and stable palm vein recognition and unlocking operations.

[0146] In some embodiments of this application, by limiting the range of the angle between the optical axis of the recognition camera and the vertical direction to a reasonable range, the recognition range of the recognition camera can be adapted to the palm angle of most users. This ensures recognition effect and efficiency while allowing users to perform palm biometric unlocking at a more comfortable angle.

[0147] In some embodiments, the palm biometric module 120 further includes a supplemental lighting component 330 and an indicator component.

[0148] The supplementary lighting component 330 is used to provide supplementary lighting for the palm vein image captured by the recognition camera. For example, the supplementary lighting component 330 may include a supplementary light.

[0149] In some embodiments, the supplementary lighting assembly 330 includes at least one infrared supplementary light. The infrared supplementary light is used to provide supplementary lighting for the infrared camera. In some embodiments, the light-sensing wavelength range of the identification camera 121 is 700nm-1100nm, and the wavelength range of the infrared supplementary light is 800nm-1000nm.

[0150] For example, the resolution of the recognition camera 121 can be 1280×720 pixels, the light-sensing wavelength range of the recognition camera 121 is 700nm-1000nm, and the supplementary lighting component 330 includes an infrared supplementary light, the infrared supplementary light model is C789, the emission wavelength is 850nm, and the emission power is 1W.

[0151] For example, the resolution of the recognition camera 121 can be 1920×1080 pixels, the light-sensing wavelength range is 800nm-1100nm, and the supplementary light component 330 includes two infrared supplementary lights, the infrared supplementary light model is E345, the light emission wavelength is 940nm, and the light emission power is 0.5W.

[0152] In some embodiments of this application, by setting at least one infrared fill light and setting a reasonable wavelength range for the recognition camera and the wavelength range for the infrared fill light, the recognition effect of palm biometrics can be better guaranteed.

[0153] In some embodiments of this application, by setting up a supplementary lighting component, supplementary lighting can be provided in poor lighting conditions, thereby ensuring the recognition effect of the palm biometric door lock and improving the user experience.

[0154] Figure 6 is an exemplary schematic diagram of a recognition camera scanning and recognizing a palm according to some embodiments of this application.

[0155] In some embodiments, as shown in Figures 3 and 6, the smart lock 100 also includes an indicator component.

[0156] The indicator component is a component used to guide a user to place their palm in the correct position. In some embodiments, the indicator component includes an indicator light 340 on the palm biometric module 120 and an indicator mark 610 on the door lock body 110.

[0157] In some embodiments, as shown in FIG3, the indicator component includes three indicator lights 340 disposed on the palm biometric module 120 (e.g., next to the recognition camera 121). The three indicator lights 340 are red, green, and blue light-emitting diodes, respectively. For example, the red, green, and blue light-emitting diodes can represent recognition failure, recognition success, and recognition error, respectively. In some embodiments, the indicator component may also include only one indicator light 340, using different colors or different flashing frequencies to represent different recognition results.

[0158] In some embodiments, as shown in FIG6, the indicator 610 may be disposed on the outside of the door lock body 110, and the position may be above the position of the indicator light 340. When the indicator light 340 is lit, the indicator 610 may be illuminated to guide the user. In some embodiments, the indicator 610 is palm-shaped.

[0159] In some embodiments of this application, by setting an indicator component, the working status of the palm biometric module can be indicated, and the user can be guided to place their palm in the correct position, thereby improving recognition efficiency.

[0160] Figure 7 is an exemplary structural diagram of a palm vein recognition door lock according to some embodiments of this application.

[0161] In some embodiments, as shown in FIG7, the first mounting bracket 131 is provided with at least three mounting through holes 180 including via holes.

[0162] Mounting through hole 180 refers to a through hole used for mounting indicator components, recognition camera 121, and supplementary lighting components 330, etc.

[0163] In some embodiments, the indicator component, the recognition camera 121, and the supplementary lighting component 330 are each mounted in at least one of at least three mounting holes 180. For example, the three mounting holes 180 may be respectively mounted one-to-one with the indicator component, the recognition camera 121, and the supplementary lighting component 330. Alternatively, each of the indicator component, the recognition camera 121, and the supplementary lighting component 330 may be mounted in multiple mounting holes 180. For example, multiple indicator lights 340 may be mounted in multiple mounting holes 180; multiple infrared supplementary lights may be mounted in multiple mounting holes 180. Alternatively, the indicator component, the recognition camera 121, and the supplementary lighting component 330 may all be mounted in the same mounting hole 180.

[0164] In some embodiments, as shown in FIG7, the first panel 150 is provided with a through hole corresponding to the mounting through hole 180, so as to protect the internal structure while ensuring light transmission.

[0165] In some embodiments, as shown in Figures 1 and 7, a light-transmitting element 170 is provided in the mounting through hole 180 corresponding to the supplementary lighting component 330.

[0166] The light-transmitting element 170 is used to transmit the light emitted by the indicator component.

[0167] In some embodiments of this application, by providing at least three mounting through holes, the stable installation of the palm vein recognition module can be ensured, and by providing a light-transmitting element, the indicating effect of the indicator component can be ensured, thereby improving the user experience.

[0168] Some embodiments of this application also provide a door, including the smart door lock 100 described above.

[0169] In view of this, the core of this application is to provide a smart door lock that can effectively save space on the smart door lock panel and improve the neatness and rationality of the smart door lock panel layout.

[0170] Another core aspect of this application is the provision of a gate.

[0171] In related technologies, the doorbell button and the keyhole of a smart lock each occupy a separate space, resulting in an extremely unreasonable layout of the smart lock panel.

[0172] Therefore, how to overcome the above-mentioned technical defects is a problem that urgently needs to be solved by those skilled in the art.

[0173] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0210] It should be further noted that, referring to Figure 16, the smart door lock body 1000 disclosed in this application embodiment also includes a glass panel 104, a light-shielding ring 105, a sealing ring 106, a middle frame 107, a fixing bracket 108, and a lock cylinder 109.

[0211] The smart lock body 1000 and the lock body 100 can be the same component or different components.

[0212] This application also discloses a door, including a smart door lock 100 as disclosed in any of the above embodiments, and a door panel, wherein the smart door lock 100 is disposed on the door panel.

[0213] Since the door uses the smart door lock 100 disclosed in the above embodiments, the door also has the technical advantages of the smart door lock 100, which will not be described in detail in this application embodiment.

[0214] This application provides a smart door lock 100 and a door, wherein the smart door lock includes a smart door lock body and a doorbell button panel assembly. The smart door lock body has a mounting space containing a doorbell button and a lock cylinder keyhole. The doorbell button panel assembly is fastened to the mounting space and can conceal the doorbell button and lock cylinder keyhole. This smart door lock can concentrate the doorbell button and lock cylinder keyhole in one mounting space. Normally, the doorbell button panel assembly can hide the lock cylinder keyhole; when mechanical unlocking is required, the doorbell button panel assembly can be removed to expose the lock cylinder keyhole, and the key can be inserted into the lock cylinder keyhole to mechanically unlock. Compared with the prior art, the smart door lock disclosed in this application can effectively save space on the smart door lock panel, thereby further improving the neatness and rationality of the smart door lock panel layout.

[0215] Among related technologies, more advanced door locks generally have functions such as digital password verification, fingerprint recognition, facial recognition, and vein recognition. Over time, keypad marks will be left on the keypad area of ​​the door lock, making it easy for criminals to obtain the door lock password, which poses a significant security risk.

[0216] Therefore, how to improve the security performance of door locks has become a technical problem that urgently needs to be solved by those skilled in the art.

[0217] To improve the security performance of door locks, this application describes the structure of door locks in detail with reference to the accompanying drawings.

[0218] Referring to Figures 17 to 21, in order to achieve the above objectives, this application provides a door lock, including a panel glass, a camera, and a button module. The panel glass includes a substrate 01, which includes a camera area 11 and a button area 12. A light-transmitting layer 13 is provided on the front of the camera area 11, and the back of the camera area 11 corresponds to the camera. An anti-fingerprint layer 14 is provided on the front of the button area 12, and the back of the button area 12 corresponds to the button module.

[0219] The button area 12 of the panel glass in this application has an anti-fingerprint layer 14 on its front, so that no fingerprint marks are left during button pressing, thereby improving the security performance of the door lock. The camera area 11 has a light-transmitting layer 13 on its front, which can improve the lighting effect at the door lock camera.

[0220] It should be noted that the aforementioned anti-fingerprint layer 14 can be an anti-fingerprint film or a frosted layer. Any structure that does not leave a fingerprint mark when pressed on it can be understood as the anti-fingerprint layer 14.

[0221] The aforementioned cameras may include one or more of the following: facial recognition cameras, vein recognition cameras (palm vein, facial vein, etc.), and surveillance cameras (fisheye, image, etc.).

[0222] As shown in Figures 17 to 20, the area of ​​the anti-fingerprint layer 14 is not less than the area of ​​the button area 12, and the anti-fingerprint layer 14 covers the entire button area 12. Because the anti-fingerprint layer 14 covers the entire button area 12, fingerprints pressed on the button area 12 will not leave any marks.

[0223] It should be noted that button area 12 can be understood as the smallest area encompassing all buttons, as shown in the figure. Its shape is related to the arrangement of all buttons. In the figure, the buttons are arranged in a rectangular pattern, therefore button area 12 is a rectangular structure; if the buttons are arranged in a circular pattern, then button area 12 is circular.

[0224] The shape of the anti-fingerprint layer 14 may be the same as or different from the shape of the button area 12. For example, in the figure, the shape of the button area 12 is rectangular, and the shape of the anti-fingerprint layer 14 is also rectangular, but its area is larger than that of the button area 12. Other shapes of the anti-fingerprint layer 14 are also possible, which will not be elaborated here.

[0225] In addition, except for the camera area 11, the entire front of the substrate 01 is provided with an anti-fingerprint layer 14 to prevent fingerprints from remaining on areas other than the button area 12, thereby further improving security.

[0226] As shown in Figure 21, the button area 12 includes at least two sub-button areas 1210, and the anti-fingerprint layer 14 includes at least two sub-anti-fingerprint layers 1410. The sub-anti-fingerprint layer 1410 corresponds one-to-one with the sub-button area 1210, that is, one sub-button area 1210 corresponds to one sub-anti-fingerprint layer 1410.

[0227] The area of ​​the sub-fingerprint-proof layer 1410 is not less than the area of ​​the sub-button area 1210; the sub-fingerprint-proof layer 1410 covers the entire sub-button area 1210. Therefore, no fingerprint marks will be left when the button is pressed.

[0228] The shape of the aforementioned sub-fingerprint-proof layer 1410 may be the same as or different from the shape of the sub-button area 1210. In the illustration, the sub-button area 1210 is circular, and the sub-fingerprint-proof layer 1410 is also circular. Alternatively, the shape of the sub-button area 1210 can also be rectangular, elliptical, etc. In this application, the number and structural form of the sub-button areas 1210 can be adjusted according to requirements. The illustration shows 11 circular sub-button areas 1210, each with its own sub-fingerprint-proof layer 1410.

[0229] In some examples, the back of the sub-button area 1210 is provided with a semi-transparent black layer, which hides the sub-button area 1210 when the button is not illuminated. Of course, in some examples, the back of the sub-button area 1210 may not have a semi-transparent black layer, and the aforementioned semi-transparent black layer is a silkscreen semi-transparent black layer.

[0230] The sub-button area 1210 can be either flat or curved. When the sub-button area 1210 is curved, the anti-fingerprint layer 1410 is a frosted layer, which improves the tactile feel of pressing the button. When the sub-button area 1210 is flat, the anti-fingerprint layer 14 can be an anti-fingerprint film, which is easy to apply and reduces the cost of the glass panel.

[0231] The light-transmitting layer 13 of the aforementioned camera area 11 is made of light-transmitting material to facilitate image acquisition; specifically, it is a glossy light-transmitting layer 13.

[0232] The camera area 11 can be understood as the smallest area that encloses all the buttons, as shown in the figure. Its shape is related to the arrangement of all the cameras.

[0233] The shape of the light-transmitting layer 13 may be the same as or different from the shape of the camera area 11. For example, in the figure, the camera area 11 is rectangular, and the shape of the light-transmitting layer 13 is also rectangular, but its area is larger than that of the camera area 11. Other shapes of the light-transmitting layer 13 are also possible, which will not be elaborated here.

[0234] The camera area 11 may include multiple sub-camera areas 1110, each sub-camera area 1110 corresponding to one camera. The light-transmitting layer 13 includes at least two sub-light-transmitting layers 1310, each sub-light-transmitting layer 1310 corresponding to one sub-camera area 1110, that is, one sub-camera area 1110 corresponds to one sub-light-transmitting layer 1310.

[0235] The area of ​​the sub-transparent layer 1310 is not less than the area of ​​the sub-camera area 1110; the sub-transparent layer 1310 covers the entire sub-camera area 1110. This improves the lighting effect of the sub-camera area.

[0236] The shape of the aforementioned sub-light-transmitting layer 1310 may be the same as or different from the shape of the sub-camera area 1110. In the illustration, the sub-camera area 1110 is circular, and the sub-light-transmitting layer 1310 is also circular. Alternatively, the shape of the sub-camera area 1110 can also be rectangular, elliptical, etc. In this application, the number and structural form of the sub-camera areas 1110 can be adjusted according to requirements. The illustration shows 11 circular sub-camera areas 1110, each with its own sub-light-transmitting layer 1310.

[0237] In some examples, an infrared ink layer is provided on the back of the sub-camera area 1110, and the sub-camera area 1110 is hidden when the button is not illuminated. Of course, in some examples, the back of the sub-camera area 1110 may not have an infrared ink layer, and the aforementioned infrared ink layer may be printed.

[0238] In the examples described above, substrate 01 is one or more alkaline earth metal oxides selected from MgO, CaO, SrO, and BaO. Substrate 01 with the above structure can improve the physical properties of the glass panel and enhance its wear resistance and thermal shock resistance.

[0239] The door lock provided in this application includes a panel glass, a camera, and a button module. The panel glass includes a substrate, which includes a camera area and a button area. A light-transmitting layer is provided on the front of the camera area, and the back of the camera area corresponds to the camera. An anti-fingerprint layer is provided on the front of the button area, and the back of the button area corresponds to the button module. Because the panel glass of this application has a light-transmitting layer on the camera area and an anti-fingerprint layer on the front of the button area, the lighting effect at the door lock camera is improved, and no fingerprint marks are left during button presses, thereby improving the security performance of the door lock.

[0240] In some embodiments, the technical solution of the door lock in Figures 17 to 21 can be applied to the smart door lock 100 in other views.

[0241] In related technologies, charging smart locks typically involves using a data cable to connect a power bank or a data cable to a charger connected to a power outlet. However, when a smart lock suddenly runs out of power, it becomes inconvenient to use a power bank or charger, causing difficulty in opening the door and negatively impacting the user experience.

[0242] As shown in Figures 22 to 24, the solar charging device in this embodiment includes a second connector 1, a first housing 2, and a second housing 3. The first housing 2 has a first mounting cavity 21, and the second housing 3 has a second mounting cavity 31. Solar panels 10 are disposed in both the first mounting cavity 21 and the second mounting cavity 31. Both the first housing 2 and the second housing 3 are connected to the second connector 1, and the first housing 2 and the second housing 3 can rotate relative to each other via the second connector. The first mounting cavity 21 and the second mounting cavity 31 are connected through a first wire hole 5 passing through the second connector 1, so that the solar panels 10 in the first housing 2 and the solar panels 10 in the second housing 3 are connected via a cable passing through the first wire hole 5.

[0243] For example, the first housing 2 and the second housing 3 can be rotated relative to each other via the second connector 1 to a folded state where they are close together and an unfolded state where they are distributed 180°. In the folded state, the solar panels 10 inside the first housing 2 and the second housing 3 are close together. In the unfolded state where they are distributed 180°, the solar panels 10 inside the first housing 2 and the second housing are located on the same side, so that they can be charged simultaneously by solar energy. Therefore, when it is necessary to store or transport the solar charging device, the first housing 2 and the second housing 3 can be rotated relative to each other to the folded state. When it is necessary to charge the solar charging device, the first housing 2 and the second housing 3 can be rotated relative to each other to the 180° distributed state. The first shell 2 and the second shell 3 have a folded state that fits together and an unfolded state that is distributed at 180°. This does not mean that the relative positions of the first shell 2 and the second shell 3 are only in the folded state that fits together and the unfolded state that is distributed at 180°. The first shell 2 and the second shell 3 can also be rotated relative to each other to other required angles. For example, the first shell 2 and the second shell 3 can also be distributed at angles of 45°, 90°, 120° or 160°, etc., which are not limited here.

[0244] In some embodiments, the solar charging device can be used to charge the smart door lock 100 of this application, or it can be used in conjunction with the smart door lock 100 of this application.

[0245] For example, as shown in FIG26, the second connector 1 can be a square shaft, and the two opposite sides of the second connector 1 are provided with rounded corners so that the first housing 2 and the second housing 3 can rotate around the second connector 1.

[0246] The outer contours of both the first housing 2 and the second housing 3 can be square. Of course, the shapes of the first housing 2 and the second housing 3 can be set as needed and are not intended to limit this application.

[0247] Process holes can be provided on the second connector 1 to improve its overall strength. The location, shape, and number of process holes can be set according to actual needs, and will not be detailed here.

[0248] In this embodiment, as shown in FIG24, the first mounting cavity 21 and the second mounting cavity 31 are connected through the first wire hole 5 penetrating the second connector 1.

[0249] The first mounting cavity 21 and the second mounting cavity 31 are connected by a first wire hole 5 that passes through the second connector 1. Specifically, the first wire hole 5 passes through the side wall of the first mounting cavity 21 adjacent to the second connector 1, and the side wall of the second connector 1 and the second mounting cavity 31 adjacent to the second connector 1 in sequence.

[0250] It is understood that the first housing 2 is provided with a first mounting cavity 21, and the second housing 3 is provided with a second mounting cavity 31. Solar panels 10 can be installed inside both the first housing 2 and the second housing 3. Both the first housing 2 and the second housing 3 can rotate relative to the second connector 1. When the first housing 2 and the second housing 3 are rotated to a folded state, it facilitates the storage or transportation of the solar charging device. When the first housing 2 and the second housing 3 are rotated to an unfolded state, the light-receiving area is increased, facilitating charging through the solar panels 10. When it is necessary to charge electronic devices, solar energy can be used to charge the solar charging device, which in turn charges the electronic devices, improving ease of use. Furthermore, since solar panels 10 are installed inside both the first mounting cavity 21 and the second mounting cavity 31, a first wire hole 5 connects the first mounting cavity 21 and the second mounting cavity 31, allowing the solar panels 10 in the first mounting cavity 21 and the solar panels 10 in the second mounting cavity 31 to be connected in series via a cable passing through the first wire hole 5. The cable passes through the first cable hole 5, and the inner wall of the first cable hole 5 can limit the cable, thereby making the cable distribution more orderly, improving the overall simplicity and aesthetics, and also providing protection for the cable, which is conducive to improving the user experience.

[0251] In this embodiment, as shown in FIG24, the first housing 2 is hinged to the second connector 1 via the first hinge shaft 23, and the second housing 3 is hinged to the second connector 1 via the second hinge shaft 33, and the first hinge shaft 23 and the second hinge shaft 33 are arranged in parallel and spaced apart.

[0252] It is understood that the first housing 2 is hinged to the second connector 1 via the first hinge shaft 23, and the second housing 3 is hinged to the second connector via the second hinge shaft 33. The rotation of the first housing 2 and the second housing 3 within a certain angle range can be independent of each other. When the first housing 2 and the second housing 3 are distributed at 180°, the side of the first housing 2 away from the first mounting cavity and the side of the second housing 3 away from the second mounting cavity can be located on the same plane. Thus, the side of the first housing 2 away from the first mounting cavity and the side of the second housing 3 away from the second mounting cavity can be stably fixed on a plane. At the same time, the solar panel 10 in the first groove and the solar panel 10 in the second groove can both face the direction away from the fixed plane to receive sunlight.

[0253] In this embodiment, as shown in FIG24, a first wire-passing groove 22 is provided at the bottom of the first mounting cavity 21 corresponding to the outlet of the first wire-passing hole 5. A second wire-passing groove 32 is provided at the bottom of the second mounting cavity 31 corresponding to the outlet of the first wire-passing hole 5.

[0254] It is understandable that by setting a first wire guide groove 22 at the bottom of the first mounting cavity 21 and a second wire guide groove 32 at the bottom of the second mounting cavity 31, when it is necessary to insert or pull the cable into the first wire guide hole 5, there is operating space between the cable and the bottom of the first wire guide groove 22 and the second wire guide groove 32, which makes it convenient for manual handling of the cable for insertion or pulling. This avoids the situation where the cable is close to the bottom wall of the first mounting cavity 21 or the second mounting cavity 31, which is inconvenient for operation when inserting or pulling the cable without the first wire guide groove 22 and the second wire guide groove 32.

[0255] In this embodiment, as shown in FIG24, a connecting plate 4 is provided on both the first housing 2 and the second housing 3. The first housing 2 is connected to the second connector 1 through the connecting plate 4, and the second housing 3 is connected to the second connector 1 through the connecting plate 4.

[0256] For example, connecting plates 4 are provided at both ends of the side of the first housing 2 adjacent to the second connecting member 1, and the second connecting member 1 is located between the two connecting plates 4 connected to the first housing 2. Similarly, connecting plates 4 are provided at both ends of the side of the second housing 3 adjacent to the second connecting member 1, and the second connecting member 1 is located between the two connecting plates 4 connected to the first housing 2. Each connecting plate 4 is provided with a first connecting hole, and the second connecting member 1 is provided with a second connecting hole corresponding to each first connecting hole. The connecting plates 4 and the second connecting member 1 are hinged together by hinge shafts inserted into the first and second connecting holes. Further, the connecting plate 4 connected to the first housing 2 is integrally formed with the first housing 2, and the connecting plate 4 connected to the second housing 3 is integrally formed with the second housing 3, which can improve the overall connection strength. Of course, the specific arrangement of the connecting plates 4 can be adjusted as needed, and is not limited here.

[0257] It is understandable that by setting the connecting plate 4, it is easy to connect the first housing 2 and the second housing 3 to the second connecting member 1.

[0258] In this embodiment, as shown in Figures 24 and 25, a second wire hole is provided on the side wall of the first housing 2 or the second housing 3 so that the external data cable 8 can be connected to the charging board inside the first housing 2 or the second housing 3 through the second wire hole.

[0259] Specifically, the data cable 8 passes through the second cable hole from the outside and connects to the charging board inside the first housing 2 or the second housing 3. The external end of the data cable 8 is provided with a charging plug to facilitate charging electronic products (e.g., smart locks). When the charging board is located inside the first housing 2, the second cable hole is located on the first housing 2; when the charging board is located in the second housing 3, the second cable hole is located on the second housing 3.

[0260] For example, the sidewall where the second wire hole is located can be the sidewall of the first housing 2 or the second housing 3 that is away from the second connector 1.

[0261] It is understandable that by providing a second cable hole for the data cable 8 to pass through on the side wall of the first housing 2 or the second housing 3, the data cable 8 can be limited by the hole wall of the second cable hole, which helps to make the wiring more orderly and also avoids the data cable 8 being squeezed by the folding of the first housing 2 and the second housing 3, which helps to improve the service life of the data cable 8.

[0262] In this embodiment, as shown in Figures 22, 24 and 25, a protective sleeve 6 is provided inside the second wire hole, and the data cable 8 passes through the protective sleeve 6.

[0263] Specifically, the protective sleeve 6 can have a circular cross-section, and it can wrap around the data cable 8 to provide protection for the data cable 8. For example, the protective sleeve 6 can be made of silicone.

[0264] Understandably, by setting up the protective sleeve 6 and passing the data cable 8 through the protective sleeve 6, the wall of the second cable hole can be prevented from squeezing or abrading the data cable 8, which helps to improve the service life of the data cable 8.

[0265] In this embodiment, as shown in Figures 24 and 25, the solar charging device further includes a limiting member 7, which is disposed in the first housing 2 or the second housing 3, and is used to limit the data line 8.

[0266] Understandably, by setting the limiting component 7 to limit the data line 8, the data line 8 cannot be removed from the first housing 2 or the second housing 3, thus improving the reliability of the data line 8 connection.

[0267] In this embodiment, as shown in FIG25, the limiting member 7 includes a first card holder 71, on which a first card slot is provided, and the data line 8 is inserted into the first card slot. The first card holder 71 is used to limit the data line 8 along the first direction.

[0268] Furthermore, as shown in Figure 25, the limiting member 7 also includes a second card holder 72, on which a second card slot is provided, and the data cable 8 is inserted into the second card slot. The second card holder 72 is used to limit the data cable 8 along the second direction.

[0269] Specifically, the first card holder 71 and the second card holder 72 can be integrally formed with the first housing 2 or the second housing 3 to improve the sturdiness of the first card holder 71 and the second card holder 72.

[0270] For example, the second card holder 72 is located on the side of the first card holder 71 away from the second cable guide hole, and the first direction and the second direction are arranged at an angle. For example, the first direction and the second direction are 90°, that is, the data cable 8 passes through the first card slot, bends 90°, and is then inserted into the second card slot. The position of the first card slot is opposite to the position of the second cable guide hole, and the first direction is consistent with the radial direction of the second cable guide hole. After the data cable 8 passes through the second cable guide hole, it can be easily inserted directly into the first card slot.

[0271] Furthermore, as shown in Figure 25, the limiting member 7 in this embodiment also includes a third card holder 73. The third card holder 73 is provided with a third card slot and is located between the first card holder 71 and the second card holder 72. The third card holder 73 limits the data line 8 in the first direction. By setting the third card holder 73 to limit the data line 8, the reliability of limiting the data line 8 is improved. The third card holder 73 can be integrally formed with the first housing 2 or the second housing 3.

[0272] In this embodiment, by setting a first card holder 71 and a second card holder 72, and setting a first card slot on the first card holder 71 and a second card slot on the second card holder 72, the data line 8 can be limited in the first direction and the second direction respectively, which changes the routing direction of the data line 8, increases the resistance of the data line 8 exiting from the first housing 2 and the second housing 3, and helps to improve the connection strength of the data line 8.

[0273] In this embodiment, as shown in FIG25, one end of the protective sleeve 6 abuts against the first card holder 71.

[0274] It is understandable that one end of the protective sleeve 6 located inside the first housing 2 or the second housing 3 abuts against the first retainer 71. The first retainer 71 can limit the movement, so that when the protective sleeve 6 is inserted into the second wire hole, it can be confirmed in time whether the protective sleeve 6 is installed in place, while preventing the protective sleeve 6 from entering the first housing 2 or the second housing 3.

[0275] In this embodiment, a limiting groove 9 is provided on the side of the first housing 2 that is away from the first mounting cavity 21. A limiting groove 9 is also provided on the side of the second housing 3 that is away from the second mounting cavity 31.

[0276] For example, double-sided foam tape can be installed in the limiting groove. One side of the double-sided foam tape is bonded to the limiting groove of the first housing 2 or the second housing 3, and the other side can be fixed to the side of the electronic product that needs to be charged, so as to facilitate charging of the electronic product.

[0277] In this embodiment, by providing limiting grooves on the first housing 2 and the second housing 3, it is convenient to provide fasteners (e.g., double-sided foam tape or magnets) to fix the first housing 2 and the second housing 3 within the limiting grooves.

[0278] The electronic device in this embodiment includes a device body (not shown in the figure) and the solar charging device described above, which is used to charge the device body.

[0279] Specifically, fixing members can be provided in the limiting grooves of the side of the first housing 2 away from the first mounting cavity 21 and the side of the second housing 3 away from the second mounting cavity, so as to fix the first housing 2 and the second housing 3.

[0280] For example, the device itself can be a smart lock, doorbell, or camera.

[0281] When charging the device body using the solar charging device in this embodiment, the first housing 2 and the second housing 3 can be flipped to the unfolded state, and the side of the second housing 3 facing away from the first mounting cavity 21 and the side of the second housing 3 facing away from the second mounting cavity 31 can be fixed to one side of the device body to facilitate charging the device body.

[0282] The solar charging device of the present application improves the convenience of charging, is easy to carry, has a simple appearance, and helps to enhance the user experience.

[0283] The door in this embodiment includes the aforementioned electronic device.

[0284] In some embodiments, the electronic device may be the smart door lock 100 of this application.

[0285] Specifically, the first housing 2 and the second housing 3 of the solar charging device can both be fixed to the door to charge the device body on the door.

[0286] The above embodiments belong to the technical field of charging devices, specifically disclosing a solar charging device, electronic device, and door. The solar charging device includes a second connector, a first housing, and a second housing. The first housing has a first mounting cavity, and the second housing has a second mounting cavity. Solar panels are disposed in both the first and second mounting cavities. Both the first and second housings are connected to the second connector, and the first and second housings can rotate relative to each other via the second connector. The first and second mounting cavities are connected through a first wire hole penetrating the second connector, allowing the solar panels in the first and second housings to be connected via a cable passing through the first wire hole. This application improves the convenience of charging, is easy to carry, has a simple appearance, and enhances the user experience.
