[0037] In some embodiments, a finger vein camera 3 may be provided on the sensing panel 2. The finger vein camera 3 may be an infrared CCD finger vein camera. For example, the lens of the finger vein camera 3 may be a variable focal length lens or a lens with a miniature pan-tilt unit. The FOV (Field of View) angle of the lens may be 112 degrees horizontally and 153 degrees vertically. The finger vein camera 3 may be communicatively connected to the main control unit to facilitate the overall control of the smart lock. Preferably, two finger vein cameras 3 may be provided. The finger vein cameras 3 may be arranged in a straight line in the middle of the sensing panel 2.

[0038] Optionally, such as Figure 1-2As shown, the above-mentioned induction panel may further include an infrared lamp 4. The above-mentioned infrared lamp 4 may be an infrared light-emitting diode (LED). The above-mentioned infrared lamp 4 may be used to emit near-infrared light of a specific wavelength to capture an image of a finger vein. The above-mentioned specific wavelength may be 850 nm or 760 nm. Red blood cells have an absorption peak at the above-mentioned specific wavelength, which can make the finger vein easier to be recognized by the above-mentioned dorsal finger vein camera 3. The above-mentioned infrared lamp 4 may be arranged around the above-mentioned dorsal finger vein camera. At least four infrared lamps 4 may be arranged on the above-mentioned induction panel. Among them, the above-mentioned infrared lamp 4 is communicatively connected to the above-mentioned main control unit to facilitate the main control unit to control the startup and shutdown of the above-mentioned infrared lamp 4.

[0039] Optionally, as Figure 2 shown, the arrangement of at least four of the above-mentioned infrared lamps 4 on the above-mentioned induction panel may include, but is not limited to: the "day" shape and the "well" shape. For example, Figure 2 is a schematic diagram of the "day" shape arrangement.

[0040] Optionally, as Figure 2 shown, at least one dorsal finger vein camera may be arranged on the above-mentioned induction panel. Figure 2 is an example of arranging two dorsal finger vein cameras. Among them, the angle of the FOV of the lens of a single dorsal finger vein camera is 130-160 degrees horizontally and 130-160 degrees vertically, so as to collect a more comprehensive dorsal finger image to a greater extent.

[0041] Optionally, as Figure 2 shown, the arrangement of more than two of the above-mentioned dorsal finger vein cameras includes, but is not limited to: horizontal distribution or vertical distribution. For example, Figure 2 is an example of vertical distribution.

[0042] Optionally, as Figure 4 shown, a fingerprint groove 14 may be arranged on the inner side of the above-mentioned handle. The above-mentioned fingerprint groove 14 may be the part that fits with the finger tip of the user in the use state, as Figure 2 shown as a row of finger tip-shaped grooves. A fingerprint detector is arranged at the corresponding position of the above-mentioned fingerprint groove 14. The above-mentioned fingerprint detector may be a semiconductor fingerprint head or an optical fingerprint head. The above-mentioned fingerprint detector is used to further increase the identification information of the current user and can be used as one of the alternative unlocking methods or user registration conditions to further increase the accuracy of the above-mentioned smart door lock.

[0043] Optionally, as Figure 4 shown, the inner side of the above-mentioned handle may include at least one concave structure 11. The above-mentioned concave structure 11 may be as Figure 1 and Figure 4The image shows a series of grooves forming a finger contour. In use, these grooves conform to the user's fingers. These grooves make the grip on the handle 1 more comfortable for the user.

[0044] Optionally, such as Figure 3 As shown, the aforementioned sensing panel may further include a panel mounting recess 11. The aforementioned dorsal vein camera can be disposed in the aforementioned panel mounting recess 11. The aforementioned recessed structure 11 may have an angular difference with the aforementioned sensing panel 2. The aforementioned panel mounting recess 21 can be used to adjust the distance and angle between the aforementioned dorsal vein camera 3 on the aforementioned sensing panel 2 and the user's finger in the use state, so that the aforementioned dorsal vein camera 3 can better acquire the dorsal veins of multiple fingers of the user. The depth and angle of the aforementioned panel mounting recess 21 are not specifically limited and can be set according to the actual situation.

[0045] Optionally, such as Figure 4 As shown, the inner side of the handle 1 may include a sensing area 12. The sensing sensor 5 may be disposed within the sensing area. The sensing area 12 may be embedded within the inner side of the handle 1. One end of the inner side of the handle 1 may be provided with a sensing guide protrusion structure 13. The sensing guide protrusion structure 13 may be used to guide the user to place their fingers in the corresponding positions on the inner side of the handle. In use, the sensing guide protrusion structure 13 may conform to the user's fingers.

[0046] Figure 5 This is a structural diagram of the inner side of the handle of a smart door lock according to other embodiments of this disclosure. Figure 5 It includes a sliding panel 15, a detachable sensing area 151, a fixing screw hole 16, and a connecting groove 17.

[0047] Optionally, such as Figure 1-5 As shown, the handle 1 may have a communicating groove 17 on its inner side. The handle 1 may also include a sliding panel 15. The communicating groove 17 may be a groove formed inside the handle 1, and the communicating groove 17 may penetrate the inner side of the handle 1. The sliding panel 15 may engage with the communicating groove 17. The sliding panel 15 may include a fixing screw hole 16. In the installed state, the sliding panel 15 can be fixed to the inner side of the handle 1 by bolts. The fixing screw hole 16 may be located at the corner of the sliding panel 15. For example, as... Figure 5As shown, the aforementioned fixing screw holes 16 can be located at the four corners of the aforementioned sliding panel 15. The type of bolt is not limited, as long as it is of suitable size and provides a secure hold. The aforementioned sliding panel 15 and the aforementioned connecting groove 17 form a continuous surface on the inner side of the aforementioned handle 1, making it more comfortable for the user's fingers to contact the aforementioned handle 1. The aforementioned sliding panel 15 can surround the removable sensing area 151 to protect it. The removable sensing area 151 can be inspected and replaced by sliding the aforementioned sliding panel 15 out of the aforementioned handle 1, thereby reducing the maintenance cost of the aforementioned smart lock.

[0048] In its uninstalled state, the sliding panel 15 can be a sliding structure. The sliding panel 15 may also include a detachable sensing area 151 and a detachable sensing area 151 mounting slot. The detachable sensing area 151 can be an arc-shaped structure disposed within the sliding panel 15. The detachable sensing area 151 mounting slot can be a hollow structure. The detachable sensing area 151 can be detachably disposed within the detachable sensing area 151 mounting slot. In the installed state, the sensing side of the detachable sensing area 151 is located on the outer surface inside the handle 1, allowing the sensing sensor 5 to more accurately sense the user's finger. In the installed state, the outer surfaces of the detachable sensing area 151 and the sliding panel 15 can be continuous, so that the user's tactile sensation when using the door handle is not affected. The sensing sensor 5 is disposed within the detachable sensing area 151.

[0049] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "difficulty in replacing damaged sensing areas of sliding panels." The specific factors contributing to the difficulty in replacing damaged sensing areas of sliding panels are as follows: In most door handles, the sensing area is directly embedded inside the door handle during manufacturing, making it difficult to replace if the sensor within the sensing area malfunctions or is damaged. Solving these factors resolves the problem of difficulty in replacing damaged sensing areas of sliding panels. To achieve this effect, embodiments of this disclosure design a detachable sliding panel structure, allowing the sensing area to be slid out of the door handle for repair or replacement when it malfunctions or is damaged, thus completing the replacement with a new sensing area. This improves the flexibility of sensing area replacement.

[0050] Some embodiments of this disclosure provide a smart lock, which offers a structure for recognizing finger veins and thus offers high security. Specifically, the reason why most smart locks have poor security is that fingerprint and facial recognition unlocking only acquire external information about the user through a conventional camera, lacking a structure to recognize deeper user characteristics, resulting in poor security. Based on this, some embodiments of this disclosure provide a smart lock including a handle, a sensor panel, and a main control unit. A gap exists between the handle and the sensor panel. A sensor is disposed within the handle and is communicatively connected to the main control unit. In use, the gap accommodates the user's finger, and the sensor detects the finger. A finger vein camera is disposed on the sensor panel and is communicatively connected to the main control unit. In use, the finger vein camera captures images of the finger veins of at least one finger placed in the gap. By using a finger vein camera on the sensor panel to capture the user's finger veins, and by maintaining a certain distance between the camera and the user's hand during use, the smart lock can acquire more finger vein information. Therefore, a smart door lock with a finger dorsal vein recognition structure is provided, which has higher security.

[0051] In some embodiments, a door with a smart lock may include a door body and, for example, a door lock. Figure 1-4 The corresponding smart door locks in those embodiments. The aforementioned smart door lock can be fixed to the door body by bolts or by fitting. The material of the door body is not limited, as long as it serves the basic function of a door. The aforementioned smart door lock can be located on the opening / closing side of the door body, and its specific location is not limited. The aforementioned smart door lock may also include an outer panel. The aforementioned outer panel matches the aforementioned inner panel. The aforementioned outer panel may be located on the portion of the door where the door lock is located on the outside of the door.

[0052] Some embodiments of this disclosure provide a door with a smart lock, which can provide a door with a dorsal vein lock capable of recognizing multiple finger veins. Specifically, the reason why most doors with smart locks can only recognize a single finger is that most doors with smart locks have too few dorsal vein lock cameras, which cannot collect more dorsal vein information, resulting in significant limitations. Based on this, some embodiments of this disclosure provide a door with a smart lock, which includes a door body and such as... Figure 1-4 The corresponding smart locks in those embodiments. Therefore, while ensuring the basic functions of the door, a smart lock structure with more finger vein recognition cameras is provided, mitigating the limitations of single finger vein camera recognition and improving the user experience.

[0053] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
