Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, specifically a palm vein recognition mechanism for smart door locks. Background Technology

[0002] A palm vein smart lock is a type of smart lock that uses the vein patterns in the palm of the hand for identification. It incorporates a near-infrared LED light source and an optical sensor. When a hand is placed in the lock's recognition area, near-infrared light penetrates the palm. Because hemoglobin in veins has a strong absorption capacity for near-infrared light, while surrounding tissues have a weaker absorption capacity, an image of the vein is formed on the optical sensor. The lock's built-in processor extracts features from the acquired vein image, converts it into a digital signal, and compares it with a palm vein template pre-stored in the lock. If the comparison result matches, the lock opens; if the comparison result does not match, the lock refuses to open and issues a corresponding prompt.

[0003] In actual use, the palm vein recognition mechanism of smart door locks often fails to accurately capture the palm vein image when children use the smart door lock because the position and angle of the recognition camera are fixed. Children have to raise their hands and stand on tiptoe to put their palms within the camera's recognition range. This process is not only inconvenient to operate, but also easily leads to incomplete information collection, ultimately causing recognition failure.

[0004] Therefore, those skilled in the art have provided a palm vein recognition mechanism for smart door locks to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a palm vein recognition mechanism for smart door locks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A palm vein recognition mechanism for a smart door lock includes a smart door lock body. An adjustment component is disposed inside the smart door lock body. The adjustment component includes a groove formed inside the smart door lock body. A fitting groove is formed on the top of the inner wall of the groove. A rotary motor is fixedly connected to one side of the inner wall of the groove. A connecting shaft is fixedly connected to the transmission end of the rotary motor. A worm gear is fixedly sleeved on the side surface of the connecting shaft. A worm wheel is meshed with the top of the worm gear. A rotating shaft is fixedly connected to the other side of the worm wheel. A mounting plate is fixedly sleeved on the side surface of the rotating shaft. A guide rod is fixedly connected to the other side of the mounting plate. A guide groove is formed on one side of the inner wall of the groove, and the guide groove is adapted to the guide rod. A recognition camera is fixedly connected to one side of the mounting plate.

[0008] As a further embodiment of this utility model: a password operation panel is fixedly connected to one side of the smart door lock body, a fingerprint recognition panel is provided at the bottom of the password operation panel, and a control button is fixedly connected to the bottom of the smart door lock body.

[0009] As a further improvement of this utility model: a connecting seat is fixedly connected to one side of the smart door lock body, and a handle is connected to one side of the connecting seat.

[0010] As a further improvement of this utility model: a hidden groove is provided on one side of the smart door lock body, a cover plate is movably connected inside the hidden groove, and an emergency charging port is provided on the other side of the inner wall of the hidden groove.

[0011] As a further improvement of this utility model: a flexible rubber pad is provided inside the fitting groove, the fitting groove is adapted to the mounting plate, and the guide groove and guide rod are symmetrically distributed.

[0012] As a further improvement of this utility model: the surface of the cover plate is coated with an anti-corrosion coating, and the emergency charging port is a universal Type-C interface.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By installing the adjustment component, children only need to press the control button to make the recognition camera tilt accurately downwards. This allows children to easily place their palms within the camera's recognition range without having to lift their hands or stand on tiptoe. This effectively avoids incomplete information collection due to children's inconvenience in operation, thereby significantly improving the success rate of palm vein recognition and ensuring the normal unlocking of the smart door lock.

[0015] 2. During the rotation of the mounting plate, the guide rod slides along the guide groove. This design effectively ensures the stability of the mounting plate during rotation, preventing it from shifting or shaking. The stable mounting plate ensures that the recognition camera maintains an accurate position and posture after the angle is adjusted, further improving the accuracy of image acquisition and recognition effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Reference Figure 1 - Figure 5This embodiment provides a palm vein recognition mechanism for a smart lock, including a smart lock body 1. An adjustment component 2 is disposed inside the smart lock body 1. The adjustment component 2 includes a groove 201, which is formed inside the smart lock body 1. A fitting groove 202 is formed on the top of the inner wall of the groove 201. A rotary motor 203 is fixedly connected to one side of the inner wall of the groove 201. A connecting shaft 204 is fixedly connected to the transmission end of the rotary motor 203. A worm gear 205 is fixedly sleeved on the side surface of the connecting shaft 204. A worm wheel 206 is meshed with the top of the worm gear 205. A rotating shaft 207 is fixedly connected to the other side of the worm wheel 206. A mounting plate 208 is fixedly sleeved on the side surface of the rotating shaft 207. A guide rod 209 is fixedly connected to the other side of the mounting plate 208. A guide groove 210 is formed on one side of the inner wall of the groove 201. The guide groove 210 and the guide rod 209... To accommodate this, a recognition camera 211 is fixedly connected to one side of the mounting plate 208. When a child opens the door, pressing the control button 5 activates the rotary motor 203. The transmission end of the rotary motor 203 drives the connecting shaft 204 to rotate, and the worm gear 205, which is fixedly sleeved on the side surface of the connecting shaft 204, rotates synchronously. The rotation of the worm gear 205 drives the worm wheel 206 to rotate, which in turn drives the mounting plate 208 and the rotating shaft 207 to rotate. During the rotation of the mounting plate 208, the guide rod 209 slides along the guide groove 210, ensuring the stability of the mounting plate 208 during rotation and preventing it from shifting or wobbling. The mounting plate 208 causes the recognition camera 211 to tilt downwards for the child's convenience. The child places their palm within the recognition range of the recognition camera 211, and the recognition camera 211 begins to capture the vein image of the child's palm to unlock the door.
