Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] This application provides a finger vein recognition mechanism to reduce the impact of dust in the environment on the finger vein recognition area and improve the recognition rate. The specific implementation process of this application is described below.

[0035] Please see Figures 1 to 6 The finger vein recognition device provided in this application includes:

[0036] The finger vein assembly, the track box 01 and the sliding track structure; the track box 01 is provided with a containing space, part of the finger vein assembly penetrates the track box 01 and is located in the containing space, and the side wall of the finger vein assembly is movably connected with the inner wall of the containing space through the sliding track structure; the finger vein assembly comprises a working position and a storage position, in the storage position, the identification module 02 on the finger vein assembly is located in the containing space; in the working position, the finger vein assembly is controlled to slide around the sliding track structure, so that the upper end of the finger vein assembly slides out of the containing space.

[0037] The finger vein assembly is provided with an identification module 02, which is a key component for identifying the characteristics of the user's finger vein, capturing and analyzing the fine image of the finger vein, and realizing identity verification. The track box 01 is provided with an opening, which communicates with the containing space, and part of the whole finger vein assembly can pass through the opening of the track box 01 and extend to the outside, so that the user can place the finger for identification. The side wall of the finger vein assembly is connected with the sliding track structure, and the sliding function of the finger vein assembly is realized through the sliding track structure.

[0038] The track box 01 is provided with a containing space for containing and protecting the finger vein assembly, and the opening position and size of the track box 01 need to match the finger vein assembly to ensure that the finger vein assembly can smoothly slide at the outlet.

[0039] After part of the finger vein assembly penetrates the opening on the track box 01, the two sides of the part are close to the two inner walls in the containing space, and the two sides of the part are connected with the two inner walls of the containing space through the sliding track structure, so that the finger vein is controlled to slide around the sliding track structure.

[0040] For details, please refer to Figure 3 and Figure 4 The finger vein assembly comprises a working position and a storage position, when in the working position, the identification module 02 on the finger vein assembly is in the external environment, at this time, the user can perform finger vein identification on the identification module 02; when not in use, the finger vein assembly is controlled to be in the storage position, at this time, the identification module 02 faces the containing space, and the back of the finger vein assembly is attached to the opening on the track box 01, so that the containing space is in a relatively sealed state, and thus the dust in the environment is not easy to fall on the identification module 02.

[0041] In addition, the finger vein structure is divided into an upper end and a lower end by the sliding track structure, when in the working position, the upper end carrying the identification module 02 slides out of the identification area, and the lower end slides into the containing space.

[0042] In this embodiment, the finger vein assembly is movably connected with the accommodation space in the track box 01 through the sliding rail structure. When the finger vein assembly is not needed for finger vein identification, the finger vein assembly can be controlled to slide around the sliding rail structure to be in the storage position, the identification module 02 is placed in the accommodation space to realize the protection of the identification module 02, and in use, the finger vein identification mechanism is controlled to slide to be in the working position, and the identification module 02 is slid out, thereby reducing the influence of dust and other pollutants in the environment on the identification module 02, improving the identification rate, reducing the identification error rate, and improving the user experience.

[0043] In an optional embodiment, the sliding rail structure includes sliding bosses 16 and track grooves 17. The sliding bosses 16 are arranged on both sides of the finger vein assembly, the track grooves 17 are arranged on the inner walls of both sides of the accommodation space, the sliding bosses 16 are located in the track grooves 17, and the sliding bosses 16 can move in the track grooves 17.

[0044] The sliding bosses 16 are arranged on both sides of the finger vein assembly. By arranging one sliding boss 16 on each side, the stability and balance of the finger vein assembly during sliding are ensured. The sliding bosses 16 are arranged in an integral manner with the finger vein assembly. The track grooves 17 are arranged on the inner walls of both sides of the accommodation space, corresponding to the positions of the sliding bosses 16. The track grooves 17 are arc-shaped or linear, depending on the required sliding range and space layout. The track grooves 17 not only provide a stable moving track for the sliding bosses 16, but also limit the movement range of the sliding bosses 16, ensuring that the finger vein assembly will not exceed the predetermined position during sliding.

[0045] When the finger vein assembly needs to be moved, the user can manually operate the sliding bosses 16 to move in the track grooves 17. With the movement of the sliding bosses 16, the finger vein assembly rotates around the sliding bosses 16 and gradually moves from the storage position to the working position (or vice versa). In this process, the track grooves 17 play a guiding and limiting role, ensuring smooth sliding and accurate positioning of the assembly.

[0046] Please continue to refer to Figure 2 and Figure 5 In this optional embodiment, the sliding bosses 16 include first bosses 03 and second bosses 04, the track grooves 17 include straight grooves 05 and curved grooves 06, the first bosses 03 are inserted into the straight grooves 05, and the second bosses 04 are inserted into the curved grooves 06, so that when the finger vein assembly is controlled to slide, the first bosses 03 move in the straight grooves 05 and the second bosses 04 move in the curved grooves 06.

[0047] On the same side of the accommodating space, the straight slot 05 and the curved slot 06 are arranged at the same time. In the sliding process, the first boss 03 moves linearly along the straight slot 05, and the second boss 04 moves along the curved slot 06. In the process of changing from the storage position to the working position, the second boss 04 gradually approaches the opening position on the track box 01 along the curved slot 06. When it is completely in the working position, the angle between the recognition module 02 and the track box 01 is about 90 degrees, which can be 90 degrees, 75 degrees, 95 degrees, etc. The specific angle is not limited here, and the actual implementation is used as the reference.

[0048] In this embodiment, the bottom plate 07 is arranged in the accommodating space, the second limiting block 08 is arranged on the bottom plate 07, the bottom of the finger vein assembly is provided with the limiting groove 09, and the limiting groove 09 is clamped outside the second limiting block 08 in the working position. In this embodiment, the second limiting block 08 is integrally formed with the bottom plate 07. In the process of changing from the storage position to the working position of the finger vein assembly, the limiting groove 09 is gradually sleeved and penetrated from the outside of the second limiting block 08 along with the movement of the finger vein assembly. By arranging the second limiting block 08, the excessive sliding of the finger vein assembly is avoided, and the stability of the finger vein assembly in the working position is ensured.

[0049] In this optional embodiment, the finger vein assembly includes the recognition module 02 and the module box 10. The side of the module box 10 is movably connected to the inner wall of the accommodating space through the sliding rail structure, and the recognition module 02 is embedded on the upper surface of the module box 10.

The module box 10 can slide around the sliding rail structure. In the storage position, the side of the module box 10 corresponding to the recognition module 02 faces the accommodating space, and the opposite side faces outward. The recognition module 02 can be fixed on the module box 10 in the form of bolt / screw connection, or can be fixed by means of glue.

[0051] In this optional embodiment, the module box 10 includes the front cover 11 and the rear cover 12 which are connected to each other. The recognition module 02 is fixed on the front cover 11, and the first boss 03 and the second boss 04 are arranged on the two sides of the front cover 11.

[0052] Please continue to refer to Figure 5 In this embodiment, the module box 10 is composed of the front cover 11 and the rear cover 12. The front cover 11 and the rear cover 12 are connected by means of buckling or bolt. On the two sides of the front cover 11, the first boss 03 and the second boss 04 are arranged on each side at the same time. The first boss 03 and the second boss 04 are integrally formed with the front cover 11 respectively. In the storage position, the front cover 11 faces the storage position, and the rear cover 12 faces away from the storage position (faces the outside).

[0053] In this optional embodiment, the rear cover 12 is provided with a hand hook position 13, and the hand hook is recessed from the rear cover 12 to the front cover 11. In this embodiment, in order to facilitate the user to manually control the finger vein assembly to change from the storage position to the working position, the hand hook position 13 is arranged on the rear cover 12, and the hand hook position 13 is at the upper end of the finger vein assembly. The user can exert an outward pulling force at the hand hook position 13, thereby pulling the upper end of the finger vein assembly outward, and gradually exposing the identification module 02 to the outside (i.e., the working position).

[0054] In an optional embodiment, in the storage position, the surface of the rear cover 12 is flush with the surface of the track box 01.

[0055] In this optional embodiment, the two sides of the module box 10 are provided with first limiting blocks 14, so that when the finger vein assembly is in the storage position, the first limiting blocks 14 are clamped on the inner wall of the containing space. In this embodiment, by arranging the first limiting blocks 14 on the two sides of the module box 10, the first limiting blocks 14 are clamped on the inner wall of the containing space in the storage position, thereby fixing the finger vein assembly in the storage position, preventing accidental sliding, and the first limiting blocks 14 also serve as limiting blocks to prevent the finger vein assembly from being excessively inserted into the containing space.

[0056] In an optional embodiment, the present application further includes a key body assembly 15, which is arranged on the track box 01 and adjacent to the finger vein assembly. The key body assembly 15 includes a key shell, an operation panel, a key plate, and a circuit board arranged in the key shell, and the key plate is connected to the circuit board and the operation panel.
