In terms of mobile phones, with the advancement of technology and the widespread use of full-screen mobile phones, the installation of fingerprint recognition systems under the screen of mobile phones has greatly improved the user experience and security performance. Mobile phones can use fingerprint recognition technology to unlock mobile phones and make mobile payments. Therefore, during the production process of mobile phones, it is of utmost importance to test the fingerprint recognition system under the mobile phone screen.

[0014] like Figures 1 to 4As shown, in this embodiment, the utility model includes a main body module 1 and several test modules 2, the test modules 2 are evenly distributed on the main body module 1, the test module 2 includes a locking assembly 200 and a pressing assembly 21, the main body module 1 is provided with several first guide columns 10, the locking assembly 200 includes a locking plate 2000 which is limitedly matched with the first guide column 10, the pressing assembly 21 is slidably matched with the first guide column 10, the locking assembly 200 is connected to the pressing assembly 21, a rigid rod 210 is provided on the pressing assembly 21, a weight assembly 22 is provided at one end of the rigid rod 210 close to the locking assembly 200, and a fingerprint simulation bump 23 is provided at the other end of the rigid rod 210. It can be seen that the main module 1 supports the locking component 20 and the pressing component 21, and the pressing component 21 is slidably fitted on the main module 1. The fingerprint simulation protrusion 23 simulates the force of the finger pressing the mobile phone screen through the weight of the weight component 22. Because the locking component 20 is connected to the pressing component 21, the locking component 20 is limited and matched with the main module 1 through the locking plate 200, so the pressing component 21 is also limited and matched. The locking component 20 and the pressing component 21 are evenly distributed on the main module 1, so that different forces and different fingerprint simulation protrusions 23 can be used to test the fingerprint under the mobile phone screen.

[0015] like Figure 2 As shown, in this embodiment, the main body module 1 further includes a turntable fixing seat 11 and a turntable element 12, a plurality of guide wheels 13 are evenly arranged on the turntable fixing seat 11, the guide wheels 13 are rotationally matched with the turntable fixing seat 11, the turntable element 12 is limitedly matched with the plurality of guide wheels 13, and a plurality of the first guide posts 10 are evenly fixed on the turntable element 12. It can be seen that, because the first guide posts 10 are fixed on the turntable element 12, and the first guide posts 10 are matched with the locking assembly 20 and the pressing assembly 21, the turntable element 12 is matched through the transmission of the guide wheels 13, so that the same mobile phone screen can be tested by different pressing assemblies 21.

[0016] like Figure 4As shown, in this embodiment, the locking assembly 20 further includes a locking fixed seat 201 and a moving plate 202, the locking fixed seat 201 is connected to the pressing assembly 21, the moving plate 202 is floatingly matched on the locking fixed seat 201 through an elastic body 203, the elastic body 203 is arranged between the locking fixed seat 201 and the moving plate 202, the locking fixed seat 201 and the moving plate 202 are limitedly matched, and the locking plate 200 is connected to the moving plate 202. It can be seen that the locking assembly 3 uses the elastic body 203 to floatly match with the locking fixed seat 201, and the locking plate 200 is connected and matched with the moving plate 202. When the operator presses the moving plate 202, the locking plate 200 moves away from the first guide column 10, so that the limiting relationship with the main module 1 is destroyed, and the pressing assembly 21 moves due to the weight of the counterweight.

[0017] like Figure 2 As shown, in this embodiment, both sides of the circular edge of the turntable element 12 are provided with chamfers, and the chamfers are matched with the outer edge of the guide wheel 13. It can be seen that when the turntable element 12 and the guide wheel 13 are in transmission cooperation, the guide wheel 13 drives the turntable element 12 to rotate, so that different forces and different pressing components 21 can be used to test the fingerprint under the mobile phone screen.

[0018] like Figure 1 to Figure 2 As shown, in this embodiment, the turntable fixing seat 11 is provided with holes, and the turntable element 12 is provided with a plurality of notches corresponding to the plurality of rigid rods 210, and the rigid rods 210 pass through the holes and the notches. It can be seen that the holes provided on the turntable fixing seat 11 and the notches provided on the turntable element 12 are to allow the rigid rods 210 to slide and cooperate, so that the turntable element 12 will not be constrained by the turntable fixing seat 11 during rotation, and different rigid rods 210 can slide to test the fingerprint under the mobile phone screen.

[0019] like Figure 3 As shown, in this embodiment, the weight assembly 22 includes a plurality of counterweights 220, a weight fixing plate 221 and a plurality of second guide posts 222, the second guide posts 222 are fixed on the weight fixing plate 221, the weight fixing plate 221 is slidably matched with the first guide post 10, and the plurality of counterweights 220 are slidably matched with the second guide posts 222. It can be seen that the second guide post 222 is fixed on the weight fixing plate 221, the counterweight 310 is slidably matched with the second guide post 222, and the counterweight 310 is stacked up and down, so different numbers of the counterweights 310 can be placed on the weight fixing plate 221 according to the test requirements.

[0020] In this embodiment, the working principle of the utility model is as follows:

[0021] like Figures 1 to 4 As shown, when a mobile phone needs to be tested for an under-screen fingerprint, the operator fixes the mobile phone to be tested on the test fixture below the main body module 1, rotates the guide wheel 13, and places one of the pressing components 21 on the main body module 1 facing the mobile phone to be tested. Then, according to the test requirements, a number of the counterweight weights 310 are stacked on the weight component 22, and then the movable plate 22 is pressed. Due to the gravity of the counterweight weights 310, the pressing component 21 drives the fingerprint simulation protrusion 23 to move downward and contact the mobile phone to be tested. After the test is completed, the operator manually resets the pressing component 21 and limits it with the locking plate 200. This is repeated multiple times to complete the test of the fingerprint under the mobile phone screen.

[0022] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
