[0090] The transmitter 7 and the receiver 8 are arranged on the two sides of the light supplement lamp 402 respectively, and correspondingly, the light shield cover 9 has a second accommodating groove 902 and a third accommodating groove 903, and the transmitter 7 and the receiver 8 are arranged in the second accommodating groove 902 and the third accommodating groove 903 respectively.

[0091] For example, the wake-up module 6 can be an infrared distance measuring sensor, the transmitting end of the infrared distance measuring sensor is used as the transmitter 7, and the receiving end of the infrared distance measuring sensor is used as the receiver 8, the transmitting end of the infrared distance measuring sensor can emit infrared signals, and the receiving end of the infrared distance measuring sensor can receive infrared signals.

[0093] The infrared distance sensor is connected with the control module 5, and can transmit the distance information collected by the infrared distance sensor to the control module 5 in real time; the control module 5 compares the distance information with a preset value; when the infrared distance sensor detects that the distance between the object and the infrared distance sensor is less than or equal to the preset value, the control module 5 controls the recognition module 4 to start the camera of the camera assembly 401 and the light supplement lamp 402; when the infrared distance sensor detects that the distance between the object and the infrared distance sensor is greater than the preset value, the control module 5 controls the recognition module 4 to not start the camera of the camera assembly 401 and the light supplement lamp 402.

[0097] Therefore, when the infrared distance sensor detects that the distance between the object and the infrared distance sensor is less than or equal to the preset value, the control module 5 controls the sound module 10 to play voice, and the specific voice content can be set according to the identification requirement.

[0098] The biometric component of the embodiment of the utility model can play voice when collecting identification information, for example, playing voice guiding the user to correctly collect (enter) information on the biometric component, so that the comfort degree of user experience can be greatly improved.

[0099] In some embodiments, the biometric component of the embodiment of the utility model further comprises a light module 11, and the light module 11 is connected with the control module 5.

[0100] The light module 11 is arranged on the circuit board 3, so as to expose the light module 11 on the circuit board 3 to the outside; the size of the circuit board 3 is set to be greater than the size of the shell 1, that is, the diameter of the circuit board 3 is set to be greater than the diameter of the end surface of the shell 1 in contact with the circuit board 3, so that part of the circuit board 3 can be exposed to the outside, and thus the light module 11 can be arranged on the part of the circuit board 3 exposed to the outside.

[0101] It can be understood that when the diameter of the circuit board 3 is set to be greater than the diameter of the end surface of the shell 1 in contact with the circuit board 3, the first notch 3011 and the second notch 3021 on the circuit board 3 in the above embodiment will not be provided.

[0102] As shown in the figure, the light module 11 is a lamp bead 111, and the lamp bead 111 is at least a plurality of lamp beads 111 arranged on the external circuit board 3 along the circumferential direction of the circuit board 3.

[0103] Correspondingly, the shell 1 is provided with a light transmission ring 112 relative to the external part of the circuit board 3, which can make the light emitted by the lamp bead 111 more uniform, and can also avoid the light of the lamp bead 111 from stimulating the user's eyes and affecting the user's experience.

[0104] Therefore, when the infrared distance sensor detects that the distance between the object and the infrared distance sensor is less than or equal to the preset value, the control module 5 controls the light module 11 to turn on the light, which can guide the user to the position of the biometric component and facilitate the user to identify the position of the biometric component.

[0105] It can be understood that the function of the light module 11 is to guide the user to the position of the biometric component, that is, the light module 11 should be turned on before the user starts to identify on the biometric component.

[0106] Therefore, the preset value of the control module 5 controlling the light module 11 to turn on the light tube can be set to be greater than the preset value of controlling the camera and the voice module in the above embodiment, that is, the light module 11 is turned on before the user starts to identify on the biometric component, which can further improve the comfort of the user experience.

[0107] Optionally, the lamp bead 111 can be a multi-color lamp bead 111, and the control module 5 can display different colors by controlling the lamp bead 111 to show the identification state to the user, for example, when the user identification is successful, the control module 5 controls the lamp bead 111 to display green, and when the user identification fails, the control module 5 controls the lamp bead 111 to display red, which can more intuitively inform the user of the identification result, and further improve the comfort of the user experience.

[0108] The biometric component of the embodiment of the utility model can turn on the light module 11 before identifying on the biometric component to guide the user to the position of the biometric component, and can also display different colors according to the identification result of the user.

[0109] In some embodiments, the biometric component of the embodiment of the utility model further comprises a communication module 12, which is arranged on the circuit board 3, and the communication module 12 is connected with the control module 5.

[0110] Optionally, the communication module can be a WiFi, 4G communication module and a 5G communication module.

[0111] Therefore, the control module 5 can send the identification result to the outside world by using the communication module 12, for example, send the identification result to the cloud database as an identification record for storage, so as to facilitate the user to view.

[0112] In some embodiments, the circuit board 3 is provided with a wiring terminal 14 on the side away from the shell 1, and the wiring terminal 14 is connected with the control module 5.

[0113] Optionally, the rear cover 13 is provided with a third gap 133 for the wiring terminal 14 to pass through.

[0114] The biological recognition assembly of the embodiment of the utility model discloses a wiring terminal 14, which can be connected with related equipment, and the control module 5 can control the related equipment through the wiring terminal 14, for example, the related equipment is a door lock assembly, and the control module 5 can control the door lock assembly to open or close through the wiring terminal 14.

[0115] For example, the control module 5 can control the door lock assembly to open or close according to the comparison result of the identification information collected by the identification module 4 and the identification information stored in the control module 5, when the comparison result is the same, the control module 5 controls the door lock assembly to open, and when the comparison result is different, the control module 5 controls the door lock assembly to close.
