It should be understood that the handle body can be directly fixedly connected to the door body 5 according to the actual situation (not shown in the figure), as long as the basic functional requirements of the user's grip are met, they are all technical solutions defined in this application.

Wherein, the finger vein module 3 is embedded on the handle body 1, and the collection window 31 of the finger vein module 3 is arranged along the extending direction of the finger held by the user. Here, “embedded” means that the vein module 3 is described as an integral unit, and its collection window 31 is exposed to the handle body 1 .

Please also refer to FIG. 3 , which is a schematic view of the use state of the smart handle according to this embodiment. As shown in the figure, the handle body 1 is arranged vertically. When the user is holding the handle body 1 , his thumb is set approximately vertically or at a small angle to the vertical direction, and fingers except the thumb are generally set horizontally or at a small angle to the horizontal direction. Specifically, in this solution, the finger vein module 3 is embedded on the rear side of the handle body 1 . The collection window 31 is exposed on the rear side of the handle body 1 and is arranged along the lateral direction to adapt to the holding posture of other fingers except the thumb. With such a setting, in the posture of holding the vertical handle, the user's four fingers can be located at the matching acquisition window, that is, the identity verification is carried out synchronously in the posture of the user opening the door, and then after the verification is passed, the original posture directly To complete the door opening operation, one action can complete the finger vein identification and door opening operation, which is simple and reliable.

It should be noted that the orientation words such as "front" and "rear" used in this article are based on the angle at which the user faces the door lock, that is to say, the side of the handle body close to the user is the "front" side , the side of the handle body away from the user is the "rear" side. Apparently, the use of the above-mentioned orientation words is only used to clearly understand the essence of the solution, and does not constitute a limit to the scope of protection of the application.

In order to improve the processing technology, the handle body 1 preferably adopts a split structure, which can be combined with front and rear splits or upper and lower splits, which is convenient for assembly and controllable in manufacturing cost. There is an opening 111 in the middle of the rear structural member 11; the finger vein module 3 is disposed in the handle body 1, and its collection window 31 is located in the opening 111, so as to obtain user's finger vein information. At the same time, the overall appearance of the handle has no obvious convex structure. On the basis of adding the user identification function, it does not have any substantial impact on the original basic assembly relationship of the handle, and has good adaptability.

The collection window 31 is located at the back of the handle body 1 and is not within the direct line of sight of the user. It may be necessary to adjust the finger position to ensure alignment with the collection window 31 . Further, the design of the guide structure can be added. The surface of the handle body 1 around the collection window 31 is a concave curved surface 112 that fits the user's finger pulp. The user can quickly and accurately adjust the finger to the verification collection position based on the finger pulp perception. This constructs the guidance and limitation of finger placement, thereby effectively improving the recognition rate.

As shown in FIG. 1 and FIG. 4 , verification switches (not shown in the figure) are arranged at both ends of the acquisition window 31 , and the verification switches are arranged on the power supply circuit of the finger vein module 3 . Under normal conditions, the finger vein module 3 is in a standby state. When the user performs identity verification, the finger is placed on the collection window 31 to trigger the verification switch synchronously, and the finger vein recognition module starts to work after being powered on. That is to say, the finger vein module 3 and the verification system can be activated immediately after use, ensuring the service life of the system and components. The verification switch is preferably a metal capacitive touch switch, and a push switch can also be selected as required.

As shown in the figure, the outer side of the verification switch is a blind bump 32. On the one hand, it is more convenient for the user to perceive. At the same time, the blind bump 32 has the function of guiding and limiting, and cooperates with the concave surface 112 on the outer periphery of the collection window 31 to maximize Maximize the recognition rate. Specifically, the blind bump 32 can be set on the rear structural member 11, or it can be integrated on the finger vein module 3 and adopt an integrated design with the rear structural member, as long as it can meet the needs of the power supply line after the user triggers it. The general functional requirements are all within the protection scope of this application.
