[0007] The above structure facilitates the connection between the fingerprint collection device and the storage end, avoiding the carrying restriction caused by the fixed line and the breakage at the connection between the connecting line and the shell.

[0008] Preferably, a groove is provided at the bottom of the inner wall of one end of the installation groove away from the rotation groove, and the first rebound component is located inside the groove.

[0009] Through the above structure, the height of the baffle can be reduced, so that the slide plate and the pressure plate can be lowered to a lower position to match the rotation angle of the fingerprint identifier when it is pressed down.

[0010] Preferably, the first rebound component includes a baffle fixed between the inner walls of the groove and the inner walls of the mounting groove, a slide plate is slidably provided inside the groove, a pressure plate is fixed on the top of the slide plate, and a second spring is fixed between the slide plate and the groove for pressing the pressure plate flush with the top of the shell.

[0011] Through the above structure, when the fingerprint is not collected, the bottom space of the fingerprint identifier can be blocked. When collecting fingerprints, the fingerprint identifier can be used to better collect fingerprints and limit the position of the finger.

[0012] Preferably, an arc-shaped groove for positioning fingers is provided on the top of the pressing plate.

[0013] The above structure allows the user's fingers to fit better.

[0014] Preferably, the second rebound component includes a guide rod fixed inside the guide groove, a slider is slidably provided on the guide rod, the slider is fixed on both sides of the movable end of the fingerprint identifier, and a first spring for pressing the fingerprint identifier is fixed between the slider and the bottom of the inner wall of the guide groove.

[0015] Through the above structure, the fingerprint identifier can be reset when it rotates along the rotating shaft at the rotating groove, so that the fingerprint identifier is always in the state shown in the figure and the figure after collection, and does not affect the next collection and use; at the same time, the coordinated setting of the guide groove and the slider allows the fingerprint identifier to rotate more smoothly.

[0016] The beneficial effects of the utility model are as follows:

[0017] Compared with the prior art, the device is compact and easy to carry. Through the coordinated arrangement of the fingerprint identifier, the second rebound component and the first rebound component, the fingerprint identifier can be in full contact with the finger and the finger can be positioned during fingerprint collection, thereby avoiding the knuckles from being easily suspended in the air, resulting in the collected fingerprints being unable to be read and causing low collection efficiency.

[0023] Example 1

[0024] See also Figure 1-4 The present embodiment provides a fingerprint collection device including a housing 100 and a fingerprint identifier 120. The housing 100 is provided with a mounting groove 110. One end of the inner wall of the mounting groove 110 is provided with a rotating groove 210 for rotating one end of the fingerprint identifier 120. Both sides of the inner wall of the mounting groove 110 are provided with guide grooves 220 coaxially arranged with the rotation axis of the fingerprint identifier 120. A second rebound component 230 for pressing the active end of the fingerprint identifier 120 is provided inside the guide groove 220; the housing 100 is provided with a first rebound component 130 for positioning a finger near the active end of the fingerprint identifier 120.

[0025] When using this embodiment, the user places the finger whose fingerprint is to be collected on the fingerprint identifier 120, and then presses the finger downward, and the fingerprint identifier 120 and the pressure plate 440 both move downward. At this time, the fingerprint identifier 120 is in full contact with the finger knuckles. Compared with the prior art, the device is compact and easy to carry. Through the coordinated arrangement of the fingerprint identifier 120, the second rebound component 230 and the first rebound component 130, the fingerprint identifier 120 can be in full contact with the finger, and the finger can be positioned during fingerprint collection, thereby avoiding the knuckles being easily suspended, resulting in the collected fingerprints being unable to be read, resulting in low collection efficiency.

[0026] In this embodiment, the housing 100 is provided with a data connection port 140 for plugging in a data cable.

[0027] The data connection port 140 may be located at the top of the housing 100 or at the side wall of the housing 100 .

[0032] Through the above structure, when the fingerprint is not collected, the bottom space of the fingerprint identifier 120 can be blocked. When the fingerprint is collected, the fingerprint identifier 120 can be used to better collect the fingerprint and the finger can be limited.

[0033] In this embodiment, an arc-shaped groove for positioning fingers is provided on the top of the pressing plate 440 .

[0034] The above structure allows the user's fingers to fit better.

[0035] In this embodiment, the second rebound component 230 includes a guide rod 310 fixed inside the guide groove 220, a slider 330 is slidably provided on the guide rod 310, the slider 330 is fixed on both sides of the movable end of the fingerprint identifier 120, and a first spring 320 for pressing the fingerprint identifier 120 is fixed between the slider 330 and the bottom of the inner wall of the guide groove 220.

[0036] The curvature of the guide rod 310 is consistent with that of the guide groove 220 ; a stop bar for limiting the two ends of the pressure plate 440 is fixedly provided on the top of the inner wall of the installation groove 110 to prevent the pressure plate 440 from being separated from the installation groove 110 .

[0037] Through the above structure, when the fingerprint identifier 120 rotates along the rotating shaft at the rotating groove 210, the fingerprint identifier 120 can be reset, so that the fingerprint identifier 120 is always in the same position as above after the collection is completed. Figure 1 and Figure 2 The state shown does not affect the next collection and use; at the same time, the coordinated setting of the guide groove 220 and the slider 330 allows the fingerprint identifier 120 to rotate more smoothly.
