The pressure plate 30 is fixed on the back surface 12 of the cover plate 10 , the sealing strip 40 is fixed on the opposite side of the pressure plate 30 and the joint 14 , and the sealing strip 40 seals the joint 14 . It can be understood that the cover assembly 100 is applied to a mobile terminal, which may be a mobile phone, a tablet computer, or a notebook computer. The cover assembly 100 covers the flashlight, and the flashlight emits light through the flashlight lens 20 .

The cover plate 10 and the flash lamp lens 20 are supported by the pressing plate 30, and the sealing rubber strip 40 is fixedly connected, and the sealing rubber strip 40 is pressed against the cover plate 10 and the flash lamp lens 20 to seal the The bonding seam 14 between the cover plate 10 and the flash lens 20 prevents water seepage between the cover plate 10 and the flash lens 20 and improves safety.

In this embodiment, the front 11 and the back 12 of the cover plate 10 are both flat surfaces. The front side 11 is parallel to the back side 12 . The peripheral edge of the cover plate 10 extends along the curve of the elliptical racetrack. The cover plate 10 can cover a camera module and a flash, or can cover two camera modules and a flash. The cover plate 10 is made of glass. The cover plate 10 covers the functional device in the area outside the flashlight hole 13, preventing the user from directly observing the functional device, so as to improve the appearance performance, and the cover plate 10 is opposite to the area outside the flashlight hole 13. Flash for protection. The geometric central axis of the flashlight hole 13 is substantially perpendicular to the front face 11 . The flash lamp hole 13 is formed by milling process.

In this embodiment, the flash lens 20 is fixed to the flash hole 13 . The lens 20 is parallel to the cover plate 10 . The flash lens 20 covers the flash hole 13 . The inner peripheral sidewall of the cover plate 10 at the flashlight hole 13 is closely matched with the outer peripheral sidewall of the flashlight lens 20 , and the cover plate 10 and the flashlight lens 20 are combined to form a composite cover plate. The flash lens 20 satisfies the supplementary light optical requirements for photography and shooting. The cover plate 10 does not need to meet the optical requirements for photographing and shooting. The cost of the cover plate assembly 100 is reduced. The joint seam 14 is an annular seam. The joining seam 14 is an assembly gap between the flash 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 is used to cover the flash, so that the structure of the cover 10, the flash lens 20 and the flash is stable, and the shooting performance is improved. The pressing plate 30 has a first surface 31 facing the cover plate 10 and a second surface 32 opposite to the first surface 31 . The sealing strip 40 is fixed on the first surface 31 of the pressing plate 30 . The sealing rubber strip 40 is an annular rubber strip. The sealing strip 40 is clamped between the pressing plate 30 , the cover plate 10 and the flash lens 20 . The sealing strip 40 is deformed under the clamping force between the pressure plate 30, the cover plate 10 and the flash lens 20, and seals the joint 14 to prevent water stains from coming from the cover plate 10 and the flash lens 20. Infiltrate into the bonding seam 14 between the camera lenses 20 .

Further, please refer to FIG. 4 and FIG. 5 , the flash light sheet 20 has an exit surface 22 facing the user and an incident surface 23 opposite to the exit surface 22 . The emitting surface 22 is flush with the front surface 11 . The incident surface 23 exposes the flash lamp hole 13 . The emitting surface 22 is a flat surface. The emitting surface 22 is flush with the front surface 11 , so that the side of the cover assembly 100 facing the user is flat and smooth, and the appearance structure of the cover assembly 100 is improved.

In this embodiment, the flash hole 13 has a first opening 131 disposed on the front surface 11 and a second opening 132 disposed on the rear surface 12, and the diameter of the first opening 131 is smaller than that of the second opening 132 caliber.

The cover plate 10 also has an inner peripheral 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 outgoing surface 23 , and the outer peripheral surface 21 is matched with the inner peripheral surface 133 . The joint seam 14 is formed between the outer peripheral surface 21 and the inner peripheral surface 133 . The sealant 40 exerts an elastic resisting force on both the cover plate 10 and the camera lens 20 by the supporting force of the pressure plate 30 . The cover plate 10 can be fixed relative to the pressing plate 30 . The elastic resisting force of the sealant 40 on the flash lens 20 makes the inner peripheral surface 133 and the outer peripheral surface 21 closer together, so as to reduce the width of the bonding seam 14 and increase the thickness of the cover plate. The sealing performance of the assembly 100. Since the caliber of the first opening 131 is smaller than the caliber of the second opening 132 , the flash lens 20 is not easy to push out of the flash hole 13 , and the structure of the cover assembly 100 is more stable. The incident surface 22 incident flash light. The emitting surface 23 emits flash light. The outer peripheral surface 21 is provided with a light shielding layer 24 for shielding the light from the flashlight. The flash lens 20 is arranged opposite to the flash of the mobile terminal, and the flash emits flash light through the flash lens 20 . The incident surface 22 is provided with Fresnel corrugations, so that the flash lens 20 forms a Fresnel lens. The light from the flash light enters through the incident surface 22 and exits through the exit surface 23 to form a focused beam, thereby achieving light convergence and achieving a supplementary light effect. When the flash lens 20 is applied to a mobile terminal, the incident surface 22 faces away from the user, and the outgoing surface 23 faces 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 accurately and ensures a better lighting effect. The exit surface 23 is a flat surface, so that the surface tension of the exit surface 23 is balanced, and the flash lens 20 can bear relatively large pressure on the exit surface 23 .
