[0041] A door lock is a type of lock installed on a door body. With the development of technology, smart lock-type door locks are gradually replacing the use of mechanical lock-type door locks. Among them, a smart lock usually includes a front panel assembly, a rear panel assembly, and a lock body assembly located between the two to enable the lock body assembly to be locked and unlocked through both the front panel assembly and the rear panel assembly. Further, in related technologies, more and more smart locks gradually adopt palm vein recognition technology to identify and unlock users. However, during the actual operation of the vein recognition module, when the temperature in the external environment changes greatly, especially in areas with large temperature differences between day and night. At this time, the natural air in the external environment will liquefy or vaporize after contacting the vein recognition module, resulting in fogging on the vein recognition module and affecting the recognition of the palm vein recognition module for users.

[0042] Therefore, based on the above considerations, in order to solve the problem that the recognition of the vein recognition module on the current front panel assembly is easily affected by the temperature change in the external environment, the present application proposes a new front panel assembly applied to a door lock. The front panel assembly innovatively provides a sealing shell in the accommodation cavity of the body, and the vein recognition module is arranged in the sealed cavity of the sealing shell, so as to provide a sealed space isolated from the external environment for the vein recognition module, thereby isolating the influence of the temperature change in the external environment on the recognition work of the vein recognition module.

[0043] Next, the structure of the front panel assembly proposed in the present application will be explained and described by way of embodiments. In an embodiment of the present application, please refer to Figures 1 to 6 , the front panel assembly 100 proposed in the present application includes a body 10, a sealing shell 20, and a vein recognition module 30. The body 10 is provided with an accommodation cavity 11; the sealing shell 20 is arranged in the accommodation cavity 11, the sealing shell 20 is provided with a sealed cavity 21 and an identification hole 22, the identification hole 22 communicates with the sealed cavity 21, and a light-transmitting part 12 is formed at the position of the body 10 corresponding to the identification hole 22; the vein recognition module 30 is arranged in the sealed cavity 21 and is arranged corresponding to the identification hole 22.

[0044] The body 10 can be used to provide an installation position for installing and carrying the sealing shell 20, the vein recognition module 30, and other components in the front panel assembly 100, such as a circuit board, a motor, or a communication module, etc., so as to facilitate the assembly of the various components in the front panel assembly 100 into a whole for use. Among them, when the front panel assembly 100 is in the normal use and installation state, the projection of the body 10 in the vertical plane can be rectangular, and of course, it can also be waist-shaped or oval, etc. The present application does not limit the shape of the body 10. Further, the accommodation cavity 11 provided on the body 10 can be used to install at least the sealing shell 20. That is, other components in the front panel assembly 100, such as a circuit board, a motor, or a communication module, etc., can also be provided in the accommodation cavity 11. Or, in some embodiments, other components in the front panel assembly 100 can be provided in other cavities of the body 10. In addition, the light-transmitting part 12 provided on the body 10 can be used for the vein recognition module 30 to perform external recognition. Among them, the light-transmitting part 12 and other area parts of the body 10 can be integrally structured. Of course, they can also be separately structured. For example, as introduced below, the light-transmitting plate 15 forms the light-transmitting part 12. Or, the body 10 can be entirely made of a transparent material, but except for the position corresponding to the recognition hole 22, a light-shielding layer is pasted or coated at other positions.

[0045] The sealing shell 20 can be used to form a sealing cavity 21 to improve the isolation and sealing effect on the vein recognition module 30. Among them, the sealing shell 20 can be any shape such as a cuboid or an approximate cuboid. The shape of the sealing cavity 21 can be the same as that of the sealing shell 20, so that the wall thickness of each part of the sealing shell 20 can be relatively uniform, thereby improving the manufacturing convenience. At the same time, such a setting can also realize that the sealing cavity 21 has a larger volume when the size of the sealing shell 20 is limited. Of course, in other embodiments, the shape of the sealing cavity 21 and the shape of the sealing shell 20 can also be set to be different. Further, the recognition hole 22 provided on the sealing shell 20 can be used for the vein recognition module 30 located inside the sealing shell 20 to perform external recognition. Among them, the shape of the recognition hole 22 can be the same as that of the vein recognition module 30. In addition, the sealing shell 20 can be directly connected to the body 10, and of course, it can also be indirectly connected to the body 10 through a carrier provided independently of the body 10. In addition, the sealing shell 20 can be connected to the body 10 in any connection manner such as adhesive connection, threaded connection, snap connection, or magnetic attraction connection. The present application does not limit the connection manner of the sealing shell 20 to the body 10.

[0046] The vein recognition module 30 may be a palm vein recognition module type, which obtains the image features of the palm vein and compares it with the palm vein image template pre-stored by the user in the door lock, thereby realizing the recognition of the user. Among them, since the recognition principle of the vein recognition module 30 is an existing technology, the specific structure and recognition process of the vein recognition module 30 are not described in detail here.

[0047] The front panel assembly 100 of the technical solution of the present application sets the vein recognition module 30 in the sealed shell 20 in the body 10, so that the body 10 and the sealed shell 20 can provide a closed space for accommodating the vein recognition module 30. At this time, the direct contact between the vein recognition module 30 and the external environment is isolated, so that the vein recognition module 30 can be stably in a relatively balanced temperature environment to avoid the phenomenon that the natural air in the external environment is liquefied or vaporized and fogged on the vein recognition module 30 due to temperature changes, thereby ensuring that the palm vein recognition module 30 can perform the recognition work normally and effectively, thereby improving the stability of the door lock to recognize the user. At the same time, installing the vein recognition module 30 in the sealed shell 20 and then installing it on the body 10 as a whole at one time is also conducive to improving the convenience of assembling the front panel assembly 100.

[0049] In this embodiment, the sealing shell 20 is split into a front shell 23 and a rear shell 24, so that the two can be manufactured separately and independently, and then assembled together to enclose the sealing cavity 21. At this time, the structure of the split front shell 23 and the rear shell 24 can be simplified, which is conducive to improving the convenience of manufacturing the sealing shell 20. Among them, the front shell 23 and the rear shell 24 can both be a cover structure, of course, one can also be a cover structure and the other can be a plate structure, ensuring that the sealing cavity 21 can be enclosed. In addition, the front shell 23 and the rear shell 24 can be any connection method such as adhesive connection, threaded connection, snap connection or magnetic connection, and the present application does not limit the connection method of the front shell 23 and the rear shell 24.
