[0028] It should be understood that, although the terms first, second, third, etc. may be used to describe various information in this article, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "at the time of..." or "when..." or "in response to determination".

In addition, the receiving groove 110 has a bottom wall 111 and a side wall 112 connected to the bottom wall 111, the circuit board 210 is disposed opposite to the bottom wall 111, and the fixing component 300 is disposed between the circuit board 210 and the bottom wall 111, so that the fixing component 300 can be disposed in the receiving groove 110, reducing the impact of the fixing component 300 on the appearance of the biological information collection device.

[0038] like Figures 2 to 3 As shown, in some optional embodiments, the fixing assembly 300 includes a stud 320 and a bolt 310, at least a portion of the stud 320 is disposed in the first mounting hole 211 and is electrically connected to the circuit board 210, the stud 320 has a screw hole opening toward the bottom wall 111, and the bolt 310 is connected to the bottom wall 111 and is threadedly connected to the screw hole.

[0039] In these optional embodiments, at least part of the studs 320 are disposed in the first mounting holes 211 and electrically connected to the circuit board 210, the static electricity of the circuit board 210 is discharged through the studs 320, the screw holes of the studs 320 face the bottom wall 111, and the bolts 310 are connected to the bottom wall 111 and connected to the screw holes to fix the circuit board 210 and the mounting block 100 to each other. The static electricity of the information collection module 200 is released to the mounting block 100 through the studs 320 and the bolts 310 to achieve the release of static electricity.

[0040] Optionally, in order to ensure that the stud 320 installed in the first mounting hole 211 is firmly combined with the circuit board 210 , the center line of the first mounting hole 211 on the circuit board 210 is perpendicular to the surface of the circuit board 210 .

[0041] Optionally, the outer wall of the stud 320 is fixed to the inner wall of the first mounting hole 211 by hot melt adhesive. Of course, in other embodiments, the stud 320 can also be fixed to the inner wall of the first mounting hole 211 by solder.

[0042] Optional, such as Figure 3As shown, the stud 320 may be partially located in the first mounting hole 211 , that is, one end of the stud 320 away from the bottom wall 111 is located in the mounting hole and is fixedly connected to the first mounting hole 211 by welding.

[0043] The stud 320 may also be completely located in the first mounting hole 211 and fixedly connected to the first mounting hole 211 by welding.

[0044] like Figure 3 As shown, in some optional embodiments, the circuit board 210 includes at least two first mounting holes 211, and each first mounting hole 211 is centrally symmetrically arranged.

[0046] like Figures 2 to 4 As shown, in some optional embodiments, the information collection module 200 also includes a conductive ring body 220 and a fingerprint collector 230, the conductive ring body 220 and the fingerprint collector 230 are located on the side of the circuit board 210 away from the bottom wall 111, the conductive ring body 220 is sleeved on the outside of the fingerprint collector 230, and the conductive ring body 220 is electrically connected to the circuit board 210; the conductive ring body 220 includes a second mounting hole 221, the second mounting hole 221 is connected to the first mounting hole 211, and one end of the fixing component 300 passes through the first mounting hole 211 and is connected to the second mounting hole 221.

When fingerprint recognition is performed, the finger will contact the conductive ring 220 sleeved on the outside of the fingerprint collector 230 when it is attached to the fingerprint collector 230. The conductive ring 220 is used to realize the liveness recognition function, and its main principle is to use the fact that the impedance of the metal changes with the temperature. Here, the impedance range of the conductive ring 220 can be calculated according to the normal temperature range of the human body. When the finger presses the fingerprint collector 230, due to the different temperatures of the real finger and the fake finger, the biometric information collection device detects that the impedance of the conductive ring 220 is different. When the impedance is outside the set impedance range, it is determined to be a fake finger, otherwise it is a real finger.

[0048] The conductive ring body 220 includes a second mounting hole 221, which is connected to the first mounting hole 211, and one end of the fixing component 300 passes through the first mounting hole 211 and is connected to the second mounting hole 221. The fixing component 300 is connected to the second mounting hole 221 through the first mounting hole 211 to fix the conductive ring body 220 and the mounting block 100 to each other.

[0052] In these optional embodiments, one end of the bolt 310 is connected to the bottom wall 111, and the other end of the bolt 310 is threadedly connected to the second mounting hole 221. The bolt 310 can not only fix the information acquisition module 200 and the mounting block 100, but also be reused as an electrostatic release component, so that the number of components of the biological information acquisition device is reduced and the structure is simpler.

[0056] In these optional embodiments, the third mounting hole 113 is disposed on the bottom wall 111, and the third mounting hole 113 is a through hole, so that the fixing component 300 can be installed outside the receiving groove 110. The fixing component 300 enters the receiving groove 110 from outside the receiving groove 110 through the third mounting hole 113 to connect the information collection module 200, thereby facilitating the installation of the biological information collection device.

[0057] like Figure 5 As shown, in some optional embodiments, the circuit board 210 is provided with a pin 400 on the side facing the bottom wall 111, and the bottom wall 111 is provided with an avoidance hole 500.

[0059] Optionally, the third mounting hole 113 and the avoidance hole 500 are staggered on the bottom wall 111 to avoid mutual interference between the connecting wires and the fixing assembly 300 .
