[0003] In related technologies, the identification module of the biometric unit is usually in a normally open state, which greatly increases the power consumption of the identification module and leads to high power consumption of the biometric unit. At the same time, the biometric unit in related technologies cannot back up the user's identification records, making it impossible for the user to view the identification records of the biometric unit.

At the same time, the identification records of the identification module can be sent to the cloud database for backup using the communication module, so that users can view the identification records of the biometric unit of this utility model embodiment.

[0010] Therefore, the biometric unit of this utility model embodiment has the characteristics of low power consumption and enabling users to view identification records.

[0016] In some embodiments, the biometric unit of this utility model further includes a rear cover, which is disposed on the side of the circuit board away from the cylinder and is connected to the circuit board.

[0017] In some embodiments, the circuit board is provided with a first positioning hole, the rear cover is provided with a second positioning hole corresponding to the first positioning hole, and the rear end of the cylinder is provided with a first positioning rod corresponding to the first positioning hole, the first positioning rod extending into the first positioning hole and the second positioning hole in sequence.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following is in conjunction with the appendix Figure 1-5 This invention describes a biometric identification unit according to an embodiment of the present invention.

[0027] The biometric unit of this utility model embodiment includes a cylinder 1, a first cover 2, a circuit board 3, an identification module 4, a control device 5, a wake-up module 6, and a communication module 12.

[0028] The cylinder 1 has a front end 101 and a rear end 102 opposite to each other in a first direction, and the front end 101 and the rear end 102 are respectively provided with a front port 1011 and a rear port 1021; a first cover 2 is provided on the front end 101 to seal the front port 1011. Circuit board 3 is located at the rear end 102 to close the rear port 1021; The control device 5 is located on the side of the circuit board 3 facing the outside of the cylinder 1. The identification module 4 is located on the side of the circuit board facing the inside of the cylinder, and the identification module is connected to the control module via signals.

[0029] The wake-up module 6 is located on the side of the circuit board 3 facing the inside of the cylinder 1, and the wake-up module 6 is connected to the control device 5 via signals. The communication module 12 is located on the circuit board 3, and the communication module 12 is located on the side of the circuit board facing the outside of the cylinder. The communication module 12 is connected to the control device 5 via signal.

[0030] It is understandable that when the wake-up module collects wake-up information, it transmits the wake-up information to the controller 5, and the controller 5 controls the recognition module 4 to start. When the wake-up module does not collect wake-up information, it transmits the non-wake-up information to the controller 5, and the controller 5 controls the recognition module 4 to turn off.

[0031] Meanwhile, the controller 5 can use the communication module to send the identification records of the identification module 4 to the cloud database for backup, so that users can view the identification records of the biometric unit in this embodiment of the utility model.

[0032] Therefore, the biometric unit of this utility model embodiment can start and stop the identification module 4 as needed. When identification is not required, the identification module 4 can be turned off, which can reduce the power consumption of the identification module 4 and thus reduce the power consumption of the biometric unit. At the same time, the identification records of the identification module 4 can be sent to the cloud database for backup using the communication module, so that users can view the identification records of the biometric unit of this utility model embodiment.

[0033] By setting up the communication module 12, the controller 5 can use the communication module 12 to send the identification results to the outside world, such as sending the identification results to the cloud database as identification records for storage, so that users can view them, which can further improve the comfort of using the biometric unit of this utility model embodiment.

[0034] Therefore, the biometric unit of this utility model embodiment has the characteristics of low power consumption and enabling users to view identification records.

[0035] The following is in conjunction with the appendix Figure 1-5 The biometric unit of this utility model embodiment is further described below.

[0036] like Figure 1 As shown, the biometric unit of this utility model embodiment includes a cylinder 1, a first cover 2, and a circuit board 3.

[0037] The cylinder 1 has a front end 101 and a rear end 102 opposite to each other in a first direction, and the front end 101 and the rear end 102 are respectively provided with a front port 1011 and a rear port 1021.

[0038] Furthermore, the cylinder 1 is cylindrical, and the cylindrical cylinder 1 has a front end 101 and a rear end 102 that are opposite each other in its axial direction. The first direction can be understood as the axial direction of the cylindrical cylinder 1. At the same time, the front end 101 and the rear end 102 are respectively provided with a front port 1011 and a rear port 1021, and both the front port 1011 and the rear port 1021 are connected to the internal space of the cylinder 1.

[0039] like Figure 1 As shown, the first cover 2 is located at the front end 101 to seal the front port 1011, and the circuit board 3 is located at the rear end 102 to close the rear port 1021.

[0040] By providing a first cover 2 at the front end 101 to seal the front port 1011 and a circuit board 3 at the rear end 102 to seal the rear port 1021, the first cover 2, the circuit board 3 and the cylinder 1 can jointly define the receiving cavity 103. In order to make the receiving cavity 103 a sealed space, the first cover 2 and the circuit board 3 can be connected to the front end 101 and the rear end 102 of the cylinder 1 respectively by means of adhesive bonding and hot melt welding.

[0041] Optionally, circuit board 3 can be a PCB board.

[0042] like Figure 4 As shown, the circuit board 3 has an identification module 4 on the side facing the inside of the cylinder 1, which is used to collect identification information. In other words, the identification module 4 on the circuit board 3 is located in the receiving cavity 103 defined by the first cover 2, the circuit board 3 and the cylinder 1.

[0043] It is understandable that the recognition module 4 located in the cavity 103 will not be interfered with by other components in the external space. For example, the recognition module 4 located in the cavity 103 will not be interfered with by dust generated by other components in the external space, which can avoid affecting the recognition effect of the recognition module 4 and also extend the service life of the recognition module 4.

[0044] It also includes a controller 5, which is mounted on the circuit board 3 and is connected to the identification module 4 to receive and analyze the identification information collected by the identification module 4.

[0045] Optionally, the controller 5 can be an MCU, that is, the controller 5 can be a microprocessor. The MCU can be integrated on the circuit board 3 and connected to the recognition module 4 to receive and analyze the recognition information collected by the recognition module 4. At the same time, the MCU has the function of storing data, and the user can store their biometric information (e.g., palm vein, fingerprint, face) in the MCU.

[0046] It also includes a wake-up module 6, which is located on the circuit board 3 and is connected to the controller 5 to transmit wake-up information to the controller 5.

[0047] It also includes a communication module 12, which is mounted on the circuit board 3 and connected to the controller 5.

[0048] Optionally, the communication module may be a WiFi communication module, a 4G communication module, or a 5G communication module.

[0049] Thus, the controller 5 can use the communication module 12 to send the recognition results to the outside world, such as sending the recognition results to the cloud database for storage as recognition records, so that users can view them.

[0050] In some embodiments, the identification module 4 includes a camera component 401, which includes a camera 4011. The camera 4011 is used to acquire image information. The camera 4011 is signal-connected to the control device 5 and transmits the acquired image information to the control device 5. On the one hand, the image information can be stored in the control device 5 as user-reserved information. On the other hand, the control device 5 can compare the image information with the user-reserved information.

[0051] The biometric unit of this utility model connects the camera 4011 to the control module 5. The camera 4011 can transmit the image information it collects to the control module 5. At the same time, the control module 5 can also control the working state of the camera 4011, that is, control the opening and closing of the camera 4011.

[0052] In some embodiments, the camera assembly 401 further includes a fill light 4012, which is signal-connected to the controller 5 so that the controller can control the fill light 4012 to start and stop. The circuit board 3 is provided with a light shield 9, which has a first mounting groove 901, and the fill light 402 is disposed in the first mounting groove 901 of the light shield 9.

[0053] Optionally, the supplementary light 402 is an infrared supplementary light. By setting the infrared supplementary light, the camera can be illuminated when it is acquiring image information, thereby making the image information acquired by the camera clearer.

[0054] In some embodiments, the wake-up module 6 includes a transmitter 7 and a receiver 8, wherein the transmitter 7 is used to transmit signals and the receiver 8 is used to receive signals.

[0055] The transmitter 7 and receiver 8 are respectively located on both sides of the supplementary light 402. Correspondingly, the light shield 9 has a second mounting groove 902 and a third mounting groove 903, and the transmitter 7 and receiver 8 are respectively located in the second mounting groove 902 and the third mounting groove 903.

[0056] For example, the wake-up module 6 can be set as an infrared ranging sensor, with the transmitter of the infrared ranging sensor as the transmitter 7 and the receiver of the infrared ranging sensor as the receiver 8. The transmitter of the infrared ranging sensor can emit infrared signals, and the receiver of the infrared ranging sensor can receive infrared signals.

[0057] The transmitter of the infrared ranging sensor emits infrared signals to the outside world in real time. When an object approaches the infrared ranging sensor, the infrared signal is reflected by the object to the receiver of the infrared ranging sensor. The distance between the object and the infrared ranging sensor can be calculated based on the time difference between transmission and reception. The specific measurement principle is existing technology and will not be elaborated here.

[0058] The infrared ranging sensor is connected to the controller 5 and can transmit the distance information it collects to the controller 5 in real time. The controller 5 compares the distance information with a preset value. When the infrared ranging sensor detects that the distance between the object and the infrared ranging sensor is less than or equal to the preset value, the controller 5 controls the recognition module 4 to activate the camera and the fill light 402 of the camera component 401. When the infrared ranging sensor detects that the distance between the object and the infrared ranging sensor is greater than the preset value, the controller 5 controls the recognition module 4 to not activate the camera and the fill light 402 of the camera component 401.

[0059] Therefore, the identification module 4 of this utility model embodiment, by setting up a wake-up module 6 including an infrared distance sensor and connecting the wake-up module 6 to the control device 5, can activate the identification module 4 when identification is needed and not activate the identification module 4 when identification is not needed, thereby reducing the power consumption of the biometric identification unit while meeting the identification requirements.

[0060] In some embodiments, the biometric unit of this utility model further includes a rear cover 13, which is disposed on the side of the circuit board 3 away from the cylinder 1 and is connected to the circuit board 3.

[0061] In some embodiments, the circuit board 3 is provided with a first positioning hole 301, the rear cover 13 is provided with a second positioning hole 111 corresponding to the first positioning hole 301, and the rear end 102 of the cylinder 1 is provided with a first positioning rod 104, which extends into the first positioning hole 301 and the second positioning hole 111 in sequence.

[0062] In some embodiments, there are multiple first positioning holes 301, which are spaced apart in the circumferential direction of the circuit board 3; there are multiple first positioning rods 104, which correspond one-to-one with the multiple first positioning holes 301; there are multiple second positioning holes 111, which correspond one-to-one with the multiple first positioning holes 301.

[0063] In some embodiments, such as Figure 5 As shown, the front port 1011 is provided with a front step 10111, and the first cover 2 is provided inside the front port 1011 and abuts against the front step 10111.

[0064] The biometric identification unit of this utility model can limit the first cover 2 located at the front port 1011 by setting a front step 10111 at the front port 1011. At the same time, in order to facilitate the installation of the first cover 2 into the front port 1011, a chamfer can be set at the front port 1011.

[0065] Optionally, the first cover 2 is a transparent plate. By setting the first cover 2 as a transparent plate, such as a glass plate or a transparent acrylic plate, the recognition module 4 of the image acquisition device can acquire clearer image information.

[0066] In some embodiments, the circuit board 3 has a wiring terminal 14 on the side opposite to the cylinder 1, and the wiring terminal 14 is connected to the control device 5.

[0067] Optionally, the rear cover 13 is provided with a third notch 133 for the wiring terminal 14 to pass through.

[0068] The biometric unit of this utility model embodiment is provided with a wiring terminal 14, which can be connected to related devices. The controller 5 can control the related devices through the wiring terminal 14. For example, the related devices are door lock components, and the controller 5 can control the door lock components to open or close through the wiring terminal 14.

[0069] For example, the controller 5 can control the door lock assembly to open or close based on the comparison result between the identification information collected by the identification module 4 and the identification information stored in the controller 5. When the comparison result is the same, the controller 5 controls the door lock assembly to open; when the comparison result is different, the controller 5 controls the door lock assembly to close.

[0070] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
