Description
Technical Field
[0001] This utility model relates to the field of smart door lock technology, and in particular to a physically energy-saving smart door lock. Background Technology
[0002] In today's era of rapid technological advancement, smart door locks, as a smart home product that combines convenience and security, are gradually entering thousands of households and various commercial venues. Currently, most smart door locks on the market use normally open facial recognition modules. This design exposes the camera to the external environment for extended periods, leading to a series of problems.
[0003] On the one hand, energy waste is a significant problem. In densely populated areas, such as company entrances and shopping mall doors, the frequent flow of people causes normally open facial recognition cameras to frequently trigger their wake-up mechanisms due to various factors. Common human body sensing and changes in lighting conditions can cause cameras to remain in continuous operation, constantly consuming power. This not only increases user costs but also significantly shortens battery life, requiring frequent battery replacements and causing considerable inconvenience to users.
[0004] On the other hand, component wear and false triggering are also serious problems. Exposed lenses are highly susceptible to environmental influences, easily accumulating dust and getting scratched, affecting the camera's recognition accuracy and performance. Furthermore, due to its normally open nature, the false recognition rate is high; for example, a pedestrian passing by may activate the camera, causing the door lock system to perform a large amount of unnecessary calculations, further increasing energy consumption and reducing the overall operating efficiency and stability of the door lock system. Utility Model Content
[0005] The purpose of this invention is to develop an intelligent door lock that can effectively solve the problems of energy waste, component wear and tear and false triggering.
[0006] To achieve the above objectives, this utility model discloses a physically energy-saving smart door lock, comprising: a lock body, wherein a recognition area is provided on the surface of the lock body, the recognition area being recessed within the surface of the lock body, and two parallel first guide rails and second guide rails are provided on the surface of the lock body; a camera module, the camera module being integrated into the lock body between the first guide rails and the second guide rails; a sliding cover system, the sliding cover system comprising a cover plate, a first guide mechanism and a second guide mechanism, the first guide mechanism and the second guide mechanism being fixed to the side of the cover plate facing the lock body, the first guide mechanism being slidably connected to the first guide rail, and the second guide mechanism being slidably connected to the second guide rail; and a photosensitive sensor, the photosensitive sensor being integrated with the camera module, wherein when the cover plate slides along the guide rails to expose the camera module, the photosensitive sensor is used to activate the camera.
[0007] By adopting the above scheme, the cover plate is slidably connected to the first and second guide rails on the lock body via the first and second guide mechanisms. In the non-use state, the cover plate covers the recognition area, blocking the camera module. At this time, the camera is in a turned-off state, avoiding frequent triggering and wake-up due to factors such as human body sensing and changes in light, thus greatly reducing unnecessary power consumption. Only when the cover plate slides along the guide rails to expose the camera module will the photosensitive sensor detect changes in light and activate the camera. This design ensures that the camera is only turned on when needed, effectively reducing energy waste and extending battery life. Because the camera module is integrated into the lock body and located in a recessed area within the recognition area, it is protected by the cover plate in the non-use state, preventing the lens from being directly exposed to the external environment, reducing the possibility of dust adhesion and scratches, thereby reducing component wear and extending the lifespan of the camera module.
[0008] Furthermore, a first magnetic element is provided at one end of the identification area, and a second magnetic element is provided at the other end; a third magnetic element is provided on the cover plate corresponding to the first magnetic element, and a fourth magnetic element is provided on the cover plate corresponding to the second magnetic element.
[0009] By employing the above solution, when the cover slides to one end of the recognition area, a strong magnetic force is generated between the magnetic components, enabling the cover to quickly and accurately position and close in that position. Users no longer need to laboriously adjust the cover's position, making operation easier and more convenient, and improving the smoothness and comfort of use. The magnetic attraction provides clear tactile and audible feedback when the cover opens or closes. Users can clearly perceive whether the cover has reached the correct position when operating it, avoiding repeated operations due to uncertainty about the cover's status, further enhancing convenience and user experience.
[0010] Furthermore, the first magnetic attraction element and the third magnetic attraction element are neodymium magnet groups with opposite poles, and the second magnetic attraction element and the fourth magnetic attraction element are neodymium magnet groups with opposite poles.
[0011] By employing the above-described design, the opposite poles of the neodymium magnets generate magnetic attraction instantly. When the user slides the cover close to the end of the recognition area, the neodymium magnets quickly activate, attracting the cover into place. This rapid response characteristic makes operating the cover smoother for the user, eliminating the need to wait for the cover to slowly position itself, thus greatly improving efficiency.
[0012] Furthermore, the first guide rail and the second guide rail are concave groove structures; the first guide mechanism and the second guide mechanism are convex rail structures adapted to the concave groove structure.
[0013] By adopting the above solution, the cover plate can move precisely along the slide rail during sliding without any deviation or wobbling. The structural design of the protruding slide rail and the concave slide groove makes the connection between the cover plate and the lock body more concealed, resulting in a cleaner and more aesthetically pleasing appearance. The mating parts of the slide rail and slide groove do not protrude from the surface of the lock body, avoiding any impact on the overall appearance of the door lock due to protruding components.
[0014] Furthermore, the concave groove structure and the convex rail structure are T-shaped structures.
[0015] By adopting the above solution, the T-shaped structure increases the connection area and contact points between the cover plate and the lock body, which can effectively resist the torsional force that may be generated during the sliding of the cover plate and maintain the stable sliding of the cover plate.
[0016] Furthermore, the camera module includes a telephoto lens and a wide-angle lens, with the photosensor located between the telephoto lens and the wide-angle lens.
[0017] By adopting the above approach, the telephoto lens has a longer shooting distance and stronger ability to capture distant scenes, making it suitable for shooting details such as faces and objects at a distance. The wide-angle lens, on the other hand, has a wider field of view, capable of capturing a larger area, such as simultaneously capturing environmental information around the doorway as well as multiple people approaching the door. When visitors gather at the doorway, the wide-angle lens can comprehensively record their positions and movements.
[0018] Furthermore, the photosensitive sensor is equipped with a light-shielding tube, the opening of which is parallel to the lens axis of the telephoto lens.
[0019] By adopting the above solution, various stray lights may exist in the environment where smart door locks are used, such as reflected light from walls, ceilings, or other light sources. If this stray light directly shines on the photosensor, it will cause the sensor to receive inaccurate light intensity, thus affecting the judgment of ambient light. The light-shielding tube can effectively block these stray lights, allowing only light from specific directions to enter the sensor.
[0020] Furthermore, a Hall sensor is provided inside the lock body to sense the position of the cover plate.
[0021] By employing the above scheme, the Hall sensor can accurately sense the position of the cover, thus clearly determining whether the cover is open or closed. When a user slides the cover to expose the camera module for facial recognition, the Hall sensor quickly detects the change in the cover's position and transmits the signal to the door lock's control system. Upon receiving the signal, the system can immediately activate the camera module for facial recognition. When the user slides the cover closed, the sensor detects the position change again, and the system can automatically shut down the camera module, saving power.
[0022] Furthermore, the cover plate is made of an opaque material.
[0023] By adopting the above solution, the opaque cover can prevent external light from causing unnecessary interference to the photosensitive sensor.
[0024] Furthermore, the lock body also includes a hidden gripping groove, the gripping groove is provided with anti-slip texture, and the groove opening is rounded.
[0025] By adopting the above solution, the concealed gripper groove does not affect the overall simplicity and aesthetics of the door lock when not in use, maintaining the lock's refined appearance. The anti-slip texture and rounded corners both help reduce wear on the gripper groove. The anti-slip texture distributes the pressure of fingers on the gripper groove, preventing excessive localized wear; the rounded corners reduce stress concentration at the groove edges, lowering the risk of edge wear.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional normally open facial recognition modules often trigger the wake-up mechanism due to factors such as human body sensing and changes in light. However, when this smart door lock is not in use, the cover plate covers the recognition area and blocks the camera module, keeping the camera in a closed state. This avoids these unnecessary wake-ups, effectively reducing power consumption and user costs. 2. By reducing unnecessary power consumption, the battery life is extended, the frequency of battery replacement is reduced, bringing convenience to users and reducing the trouble and extra expenses that may be caused by frequent battery replacements; 3. The camera module is integrated into the lock body and located in a recessed area within the recognition zone. When not in use, it is protected by a cover plate, and the lens is not directly exposed to the external environment, which greatly reduces the adhesion of dust, ensures the cleanliness of the camera, helps maintain its good recognition performance, avoids direct contact between the lens and external objects, reduces the possibility of scratches, protects the optical components of the camera, extends the service life of the camera module, and reduces the repair and replacement costs caused by component damage. 4. Traditional normally open designs have a high false recognition rate. A pedestrian passing by can activate the camera, causing the lock system to perform a large amount of unnecessary calculations. This smart lock, however, only activates the camera when the cover slides to reveal the camera module, triggering a change in light detected by the photosensor. This effectively reduces the false recognition rate and unnecessary calculations. With fewer unnecessary calculations, the lock system can dedicate more resources to processing valid recognition tasks, improving overall system efficiency and stability. It also reduces system malfunctions and lags that may result from accidental triggering and unnecessary calculations. Attached Figure Description

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0036] Please refer to Embodiment 1 of this utility model. Figure 1As shown, a physically energy-saving smart door lock is provided, including a lock body 1, a camera module 2, a sliding cover system 3, and a photosensitive sensor 4. The lock body 1 has a recessed recognition area 11 on its surface, and two parallel, outwardly protruding T-shaped first guide rails 111 and second guide rails 112 are provided on the upper and lower sides of the recognition area 11. The camera module 2 is integrated on the lock body 1 between the first guide rails 111 and the second guide rails 112. The camera module 2 includes a telephoto lens 21 and a wide-angle lens 22. The photosensitive sensor 4 is placed between the two lenses. The sliding cover system 3 includes a cover plate 31, a first guide mechanism, and a second guide mechanism 312. The cover plate 31 is made of 3mm thick black ABS opaque material, and its size covers the recognition area 11. When the recognition area 11 is completely covered, the outer surface of the cover plate 31 is aligned with the outer surface of the lock body 1, improving the overall aesthetics. The inner side of the cover plate 31 is fixed with a first guide mechanism and a second guide mechanism 312 with a concave T-shaped sliding groove structure. The first guide mechanism is slidably connected to the first guide rail 111, and the second guide mechanism 312 is slidably connected to the second guide rail 112. The photosensitive sensor 4 is integrated with the camera module 2. When the cover plate 31 slides along the guide rail to expose the camera module 2, the photosensitive sensor 4 is used to activate the camera. The cover plate 31 is slidably connected to the first guide rail 111 and the second guide rail 112 on the lock body 1 through the first guide mechanism and the second guide mechanism 312. In the non-use state, the cover plate 31 covers the recognition area 11, blocking the camera module 2. At this time, the camera is in the off state, avoiding frequent triggering and wake-up caused by human body sensing, light changes, etc., thereby greatly reducing unnecessary power consumption. Only when the cover plate 31 slides along the guide rail to expose the camera module 2 will the photosensitive sensor 4 detect the light change and activate the camera. This design allows the camera to be turned on only when needed, effectively reducing energy waste and extending battery life. Since the camera module 2 is integrated into the lock body 1 and located in the recess of the recognition area 11, it is protected by the cover plate 31 when not in use, which avoids the lens being directly exposed to the external environment, reduces the possibility of dust adhesion and scratches, thereby reducing component wear and extending the service life of the camera module 2.
[0037] It should be noted that the first guide rail 111 and the second guide rail 112 can be set horizontally, vertically, or tilted, as long as they can be opened by sliding. In this embodiment 1, the recognition area 11 is tilted to facilitate the recognition of the human body and keep it facing the face.
[0038] In some embodiments, to improve the sliding effect of the cover plate 31 and prevent it from detaching from the lock body 1, a first magnetic element 113 is provided at one end of the recognition area 11, and a second magnetic element 114 is provided at the other end. The cover plate 31 is provided with a third magnetic element 313 corresponding to the first magnetic element 113, and a fourth magnetic element 314 corresponding to the second magnetic element 114. When the cover plate 31 slides to one end of the recognition area 11, a strong magnetic attraction is generated between the magnetic elements, enabling the cover plate 31 to quickly and accurately position and close at that position. Users do not need to laboriously adjust the position of the cover plate 31, making operation easier and more convenient, and improving the smoothness and comfort of use. The magnetic attraction will produce obvious tactile and auditory feedback when the cover plate 31 is opened or closed. When operating the cover plate 31, users can clearly perceive whether the cover plate 31 has reached the correct position, avoiding repeated operations due to uncertainty about the cover plate 31's status, further enhancing the convenience and user experience. In this embodiment 1, the first magnetic element 113 and the third magnetic element 313 employ neodymium magnets with opposite poles, and the second magnetic element 114 and the fourth magnetic element 314 employ neodymium magnets with opposite poles. This opposite-pole design of the neodymium magnets allows for instantaneous magnetic attraction. When the user slides the cover 31 close to the end of the recognition area 11, the neodymium magnets quickly activate, attracting the cover 31 into place. This rapid response characteristic makes operating the cover 31 smoother, eliminating the need to wait for it to slowly position itself, thus greatly improving efficiency.
[0039] It should be noted that in this embodiment 1, the first guide rail 111 and the second guide rail 112 are concave groove structures; the first guide mechanism and the second guide mechanism 312 are convex slide rail structures adapted to the concave groove structure. The concave groove structure and the convex slide rail structure are T-shaped structures, which increases the connection area and contact points between the cover plate 31 and the lock body 1, effectively resisting the torsional force that may be generated during the sliding of the cover plate 31, and maintaining the stable sliding of the cover plate 31.
[0040] In some embodiments, the photosensor 4 is equipped with a light-shielding tube 41, the opening of which is parallel to the lens axis of the telephoto lens 21. In the environment where the smart door lock is used, various stray lights may exist, such as reflected light from walls, ceilings, or other light sources. If these stray lights directly illuminate the photosensor 4, it will cause the light intensity received by the sensor to be inaccurate, thus affecting the judgment of ambient light. The light-shielding tube 41 can effectively block these stray lights, allowing only light from specific directions to enter the sensor.
[0041] In some embodiments, a Hall sensor is installed inside the lock body 1, positioned at the right edge of the cover 31 when it is closed, to sense the position of the cover 31. The Hall sensor can accurately sense the position of the cover 31, thereby clearly determining whether the cover 31 is open or closed. When the user slides the cover 31 to expose the camera module 3 for facial recognition, the Hall sensor can quickly detect the change in the position of the cover 31 and transmit the signal to the door lock control system. After receiving the signal, the system can immediately start the camera module 3 to perform facial recognition. When the user slides the cover 31 to close, the sensor detects the position change again, and the system can automatically turn off the camera module 3 to save power.
[0042] It should be noted that in some embodiments, the cover plate 31 is made of an opaque material. The cover plate 31 can be made of metal or plastic. This can prevent external light from causing unnecessary interference to the photosensor 4. Furthermore, the positions of the concave sliding groove structure and the convex sliding rail structure can be interchanged.
[0043] In this embodiment 1, the lock body 1 also includes a concealed gripping groove 12. The gripping groove 12 has anti-slip textures, and its opening is rounded. The concealed gripping groove 12 does not affect the overall simplicity and aesthetics of the lock when not in use, maintaining the lock's refined appearance. Both the anti-slip textures and the rounded corners help reduce wear on the gripping groove 12. The anti-slip textures distribute the pressure of fingers on the gripping groove 12, preventing excessive localized wear; the rounded corners reduce stress concentration at the groove edges, lowering the risk of edge wear.
[0044] Operating instructions: Standby mode: Cover plate 31 covers the identification area 11, the third magnetic element 313 is attached and fixed to the first magnetic element 113, the light shield 41 completely blocks the photosensitive sensor 4, and the camera module 2 is powered off and enters sleep mode.
[0045] When recognition is required, the user touches and drags the cover plate 31 to the right. The T-shaped slide rail guide mechanism ensures that the slide is not deviated. When it reaches the right end, the fourth magnetic element 314 and the second magnetic element 114 are attracted and locked. The Hall sensor detects the displacement of the cover plate 31 and triggers the main control chip to start the photosensitive sensor 4. The photosensitive sensor 4 detects the ambient light through the light shield 41. After confirming exposure, it activates the camera module 2 to perform face recognition.
[0046] After the reset is complete and recognition is finished, push the cover 31 to the left. The first magnetic element 113 and the third magnetic element 313 will then attract and close the module. The Hall sensor detects the position signal, and the main control chip immediately cuts off the power to the camera module 2.
[0047] It should be noted that the camera module 2 may contain only one telephoto lens 21, and the magnetic element may be replaced with a ferrite magnet to reduce costs.
[0048] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional normally open facial recognition modules often trigger the wake-up mechanism due to factors such as human body sensing and changes in light. However, when the smart door lock is not in use, the cover plate 31 covers the recognition area 11 and blocks the camera module 2, and the camera is in a closed state, avoiding these unnecessary wake-ups, effectively reducing power consumption and reducing user operating costs. 2. By reducing unnecessary power consumption, the battery life is extended, the frequency of battery replacement is reduced, bringing convenience to users and reducing the trouble and extra expenses that may be caused by frequent battery replacements; 3. The camera module 2 is integrated into the lock body 1 and located in the recess of the recognition area 11. When not in use, it is protected by a cover plate 31, so the lens is not directly exposed to the external environment, which greatly reduces the adhesion of dust, ensures the cleanliness of the camera, helps maintain its good recognition performance, avoids direct contact between the lens and external objects, reduces the possibility of scratches, protects the optical components of the camera, extends the service life of the camera module 2, and reduces the repair and replacement costs caused by component damage. 4. Traditional normally open designs have a high false recognition rate. A pedestrian passing by may activate the camera, causing the lock system to perform a large amount of unnecessary calculations. This smart lock, however, only activates the camera when the cover 31 slides to expose the camera module 2, and the photosensor 4 detects a change in light. This effectively reduces the false recognition rate and unnecessary calculations. With fewer unnecessary calculations, the lock system can dedicate more resources to processing valid recognition tasks, improving overall system efficiency and stability. It also reduces system failures and lags that may result from accidental triggering and unnecessary calculations.
[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
