It can be understood that the shielding member 40 has an overall conical structure, and the cross-sectional area of the shielding member 40 gradually increases in the direction away from the connecting member 20. And a third through hole 41 is provided inside the shielding member 40, and the cross-sectional area of the third through hole 41 also gradually increases in the direction away from the connecting member 20.

[0054] Through the above settings, the shielding member 40 can shield the transition surface 12, avoid the transition surface 12 from reflecting light, causing light loss and affecting the fingerprint recognition performance of the electronic device. Further, the above settings can also prevent the shielding member 40 from blocking the light transmitted by the screen 50, so that the light transmitted by the screen 50 can reach the diaphragm surface 32 of the fingerprint module 30.

[0055] Optionally, as Figures 1 to 6As shown, in the embodiment of the present utility model, on the plane where the transition surface 12 is located, the shielding member 40 has a first projection, and the area of the first projection is adapted to the area of the transition surface 12.

[0056] As Figures 1 to 6 shown, in the embodiment of the present utility model, the area of the first projection of the shielding member 40 on the plane where the transition surface 12 is located is set to be adapted to the area of the transition surface 12. It can be understood that on the plane where the transition surface 12 is located, the shielding member 40 has a first projection, and the area of the first projection is equal to the area of the transition surface 12. Or, on the plane where the transition surface 12 is located, the shielding member 40 has a first projection, and the area of the first projection is larger than the area of the transition surface 12.

The transition surface 12 is connected to one end of the first through hole 11 close to the screen 50. The setting of the transition surface 12 can prevent the frame 10 from blocking the light transmitted by the screen 50, so that the light transmitted by the screen 50 can reach the diaphragm surface 32 of the fingerprint module 30.

[0062] When the distance between the fingerprint module 30 and the screen 50 conforms to the optical path design value, the frame body 10, the end of the connecting member 20 away from the shielding member 40, and the fingerprint module 30 can be connected through the fixing member 60 to prevent the fingerprint module 30 from loosening due to the shaking of the electronic device or other external forces, resulting in a change in the distance between the fingerprint module 30 and the screen 50.

[0063] Exemplarily, the fixing member 60 can be glue, and the frame body 10, the end of the connecting member 20 away from the shielding member 40, and the fingerprint module 30 are bonded by the glue to prevent the distance between the fingerprint module 30 and the screen 50 from changing.
