It is understood that the cover assembly 100 is applied to a mobile terminal, which may be a mobile phone, a tablet computer, a notebook computer, or the like. The cover plate assembly 100 covers the flash, which emits light through the flash lens 20.

Through the clamp plate 30 supports the apron 10 with the flash light lens 20 to fixed connection joint strip 40, joint strip 40 supports hold the apron 10 with flash light lens 20, with sealed the apron 10 with joint line 14 between the flash light lens 20 prevents to ooze between apron 10 and the flash light lens 20, has improved the security.

In the present embodiment, the front surface 11 and the back surface 12 of the cover plate 10 are both flat surfaces. The front face 11 is parallel to the back face 12. The perimeter of the cover plate 10 extends along an elliptical racetrack curve. The cover plate 10 may cover one camera module and one flash lamp, and may also cover two camera modules and one flash lamp. The cover plate 10 is made of glass. The cover plate 10 covers the functional device in the region outside the flash hole 13 to prevent the functional device from being directly observed by a user to improve appearance performance, and the cover plate 10 protects the flash in the region outside the flash hole 13. The geometrical centre axis of the flash hole 13 is substantially perpendicular to the front face 11. The flash lamp hole 13 is formed by a milling process.

In the present embodiment, the strobe lens 20 is fixed to the strobe hole 13. The lens 20 is parallel to the cover plate 10. The flash lens 20 covers the flash hole 13. The inner peripheral side wall of the cover plate 10 at the flash lamp hole 13 is tightly matched with the outer peripheral side wall of the flash lamp lens 20, and the cover plate 10 and the flash lamp lens 20 are combined to form a composite cover plate. The flash lens 20 meets the optical requirements for light supplement in photography. The cover plate 10 does not need to meet the optical requirements for image capture. The cost of the cover plate assembly 100 is reduced. The joint seam 14 is an annular seam. The joint seam 14 is a fitting gap between the strobe lens 20 and the cover plate 10.

In this embodiment, the pressing plate 30 supports the cover plate 10 and the flash lens 20 and presses the flash to stabilize the structure of the cover plate 10, the flash lens 20 and the flash, thereby improving the shooting performance. The pressing plate 30 has a first surface 31 facing the cover plate 10 and a second surface 32 disposed opposite to the first surface 31. The sealing rubber strip 40 is fixed to the first surface 31 of the pressing plate 30. The sealing rubber strip 40 is an annular rubber strip. The sealing rubber strip 40 is clamped between the pressing plate 30, the cover plate 10 and the flash lamp lens 20. The sealing rubber strip 40 is deformed under the clamping force of the pressing plate 30, the cover plate 10 and the flash lamp lens 20 to seal the joint seam 14, so that water stains are prevented from permeating into the joint seam 14 between the cover plate 10 and the camera lens 20.

Further, referring to fig. 4 and 5, the flashlight piece 20 has an exit surface 22 facing the user and an incident surface 23 disposed opposite to the exit surface 22. The exit face 22 is flush with the front face 11. The incident surface 23 exposes the flash hole 13. The exit surface 22 is a flat surface. The exit surface 22 is flush with the front surface 11, so that the side of the cover plate assembly 100 facing the user is flat and smooth, and the appearance structure of the cover plate assembly 100 is improved.

The first opening 131 and the second opening 132 are both circular openings. The cap plate 10 further has an inner circumferential surface 133 extending from the first opening 131 to the second opening 132. The flash lens 20 has an outer peripheral surface 21 connecting the incident surface 22 and the exit surface 23, and the outer peripheral surface 21 is fitted to the inner peripheral surface 133. The bonding seam 14 is formed between the outer circumferential surface 21 and the inner circumferential surface 133. The supporting force of the sealant 40 on the pressing plate 30 applies an elastic supporting force to both the cover plate 10 and the camera lens 20. The cover plate 10 may be fixed with respect to the pressure plate 30. The elastic support force of the sealant 40 on the flash lens 20 makes the inner circumferential surface 133 and the outer circumferential surface 21 closer to each other, so as to reduce the width of the joint seam 14 and improve the sealing performance of the cover plate assembly 100. Since the aperture of the first opening 131 is smaller than the aperture of the second opening 132, the flash lens 20 is not easily ejected out of the flash hole 13, and the structure of the cover plate assembly 100 is more stable. The entrance face 22 enters the flash light rays. The exit surface 23 emits flash light rays. The outer peripheral surface 21 is provided with a light shielding layer 24 for shielding the flash light. The flash lamp lens 20 is arranged opposite to a flash lamp of the mobile terminal, and the flash lamp emits flash lamp light through the flash lamp lens 20. The entrance surface 22 is provided with fresnel corrugations so that the flash lens 20 forms a fresnel lens. The light of the flash lamp is incident through the incident surface 22 and is emitted through the emitting surface 23 to form a condensed beam, so that the condensation is realized, and the light supplementing effect is achieved. When the flash lens 20 is applied to a mobile terminal, the incident surface 22 faces away from a user and the exit surface 23 faces toward the user. The incident surface 22 is formed by milling, and the dimensional accuracy of the incident surface 22 is high, so that the incident surface 22 refracts light precisely, and a good illumination effect is ensured. The exit surface 23 is a flat surface, so that the surface tension of the exit surface 23 is equalized, and the flash lamp lens 20 can bear a large pressure on the exit surface 23. The exit surface 23 can be formed by a polishing process, so that the exit surface 23 of the flash lamp lens 20 is smooth, impurities are not easy to remain on the exit surface 23, and the accuracy of the emergent light of the exit surface 23 is ensured.
