The camera 10 and the flash 20 are located on the second surface 304 side of the cover main body 30, i.e., the camera 10 and the flash 20 are located on the side of the housing 50. In this embodiment, the light emitted from the flash 20 travels from the second surface 304 toward the first surface 302. Referring to fig. 8, the cover main body 30 is provided with first through holes 32 communicating with opposite side surfaces of the cover main body 30, and in particular, the first through holes 32 communicate the first surface 302 with the second surface 304. With reference to fig. 4 in particular, the perpendicular projection of the flash 20 on the second surface 304 falls within the range of the first through hole 32, i.e. the flash 20 corresponds to the first through hole 32. With reference to fig. 1 and 4, the composite cover plate 300 further includes a light transmissive prism 402 and a light blocking sleeve 404, the light transmissive prism 402 and the light blocking sleeve 404 being interconnected to form the unitary body 40. In one embodiment, the light-transmissive prism 402 and the light-shielding sleeve 404 are integrally formed of a transparent material such as glass or plastic, and the light-shielding sleeve 404 is a non-light-transmissive structure formed by coating an ink layer or other light-shielding layer on the surface of the transparent material. In other embodiments, the transparent prism 402 is made of glass or plastic, the light shielding sleeve 404 is made of metal or colored plastic, and the transparent prism 402 and the light shielding sleeve 404 are integrally connected by adhering or welding. Specifically, referring to fig. 4, the light shielding sleeve 404 is received in the first through hole 32 and contacts an inner wall (the first inner wall 320) of the first through hole 32, the transparent prism 402 is located on the surface of the cover main body 30 and covers the first through hole 32, and the light emitted from the flash 20 enters the light shielding sleeve 404 and then passes through the transparent prism 402. In one embodiment, a sealing ring (not shown) is disposed between the light shielding sleeve 404 and the first through hole 32 to seal and prevent water or impurities from entering the interior of the housing 50 through the installation gap between the first light-transmitting member 42 and the light shielding sleeve 404, thereby affecting the operation of the flash lamp 20 and even damaging the flash lamp 20.

Shading sleeve 404 and printing opacity prism 402 interconnect as an organic whole and easily install or dismantle at first through-hole 32, shading sleeve 404 blocks that the flash light 20 light that gets into first through-hole 32 gets into apron main part 30 from the inner wall of first through-hole 32 and scurries light to camera 10, printing opacity prism 402 protects flash light 20 and is used for seeing through the light that flash light 20 sent outside compound apron 300, flash light 20 does not influence the normal work of camera 10, improve camera module 100 and shoot the effect, it is true to shoot picture and video picture, improve user experience.

Referring to fig. 4, in the present embodiment, the transparent prism 402 is disposed on the first surface 302. The light emitted from the flash lamp 20 enters the first through hole 32 (specifically, enters the light shielding sleeve 404 in the first through hole 32), and then passes through the light-transmitting prism 402 and propagates to the outside. The transparent prism 402 protects the flash lamp 20 from colliding with the flash lamp 20 and prevents water vapor and dust from entering the flash lamp 20. The light blocking sleeve 404 blocks light from entering the cover main body 30 from the first inner wall 320 to propagate to the camera head 10 position. Further, the vertical projection of the transparent prism 402 on the first surface 302 covers the first through hole 32, thereby enhancing the protection of the transparent prism 402 for the flash lamp 20.

In one embodiment, the light blocking sleeve 404 is an interference fit with the first through hole 32 to hold a surface of the light blocking sleeve 404 against the first interior wall 320 so that light emitted from the flashlight 20 enters the first through hole 32 without entering a gap between the light blocking sleeve 404 and the first interior wall 320.

With continued reference to fig. 4, the light-transmitting prism 402 includes an outer surface 402a facing away from the cover main body 30, the outer surface 402a is a concave curved surface, and the outer surface 402a is used for changing the propagation path of the light emitted from the flash lamp 20. Specifically, the outer surface 402a may be a spherical surface recessed in the light-transmitting prism 402, or may be an aspherical surface. The transparent prism 402 acts like a concave lens, as shown in fig. 9, when the light of the flash 20 is emitted from the outer surface 402a of the transparent prism 402, the outer surface 402a increases the divergence angle of the light, so as to expand the light coverage of the flash 20, which is beneficial to improving the shooting effect of the camera module 100.

An edge of the light-transmitting prism 402 contacts a surface of the cover main body 30, and in particular, as shown in fig. 4, the light-transmitting prism 402 further includes an inner surface 402b opposite the outer surface 402a, the inner surface 402b contacting the surface of the cover main body 30. In this embodiment, the inner surface 402b contacts the first surface 302 of the cover main body 30, so that there is no gap between the transparent prism 402 and the cover main body 30, and the light of the flash 20 emitted from the first through hole 32 enters the transparent prism 402 and is diffused by the transparent prism 402, thereby improving the utilization rate of the light of the flash 20. In one embodiment, the edge of the inner surface 402b is attached to the surface of the cover main body 30 by a light shielding adhesive, i.e., the edge of the inner surface 402b is attached to the first surface 302 by a light shielding adhesive. On the one hand, the light blocking glue fixes the light-transmitting prism 402 to the cover main body 30, and on the other hand, the light blocking glue prevents the light of the flash lamp 20 that has entered the light-transmitting prism 402 from being refracted and then emitted from the inner surface 402b to enter the cover main body 30, further preventing light leakage.

In one embodiment, the first light transmissive member 42 has a shape that is the same as the shape of the interior of the light blocking sleeve 404 so that the first light transmissive member 42 can fit seamlessly into the light blocking sleeve 404.

Referring specifically to fig. 4, in the present embodiment, the first light-transmitting member 42 abuts against the light-transmitting prism 402. Specifically, the light emitting surface 424 of the first light transmissive member 42 abuts against the inner surface 402b of the transparent prism 402, so that there is no gap between the transparent prism 402 and the first light transmissive member 42, and the light of the flash 20 passing through the first light transmissive member 42 enters the transparent prism 402 and is diffused by the transparent prism 402, thereby improving the utilization rate of the light of the flash 20. Further, the light emitting surface 424, the inner surface 402b and the first surface 302 are coplanar, and after the light of the flash lamp 20 enters the first through hole 32, the light first enters the light shielding sleeve 404, the light shielding sleeve 404 shields the light from entering the cover main body 30, and the light enters the first light-transmitting member 42 and the light-transmitting prism 402 in sequence and finally exits from the outer surface 402 a.

In one embodiment, the second through hole 34 is a circular through hole, but in other embodiments, the second through hole 34 may be a through hole with other shapes, such as a rectangular shape, a tapered shape, and the like. In this embodiment, the second through hole 34 does not intersect with the first through hole 32, so that the light path of the flash 20 and the light path of the camera 10 are separated, and mutual influence is avoided. The second light transmission piece 44 is accommodated in the second through hole 34, the second light transmission piece 44 is used for protecting the camera 10, specifically, the second light transmission piece 44 is made of a transparent material with strength greater than that of the cover plate main body 30, the second light transmission piece 44 is wear-resistant and not prone to scratching, the second light transmission piece 44 ensures long-time normal use of the camera 10, and the second light transmission piece 44 is combined with the low-cost cover plate main body 30 to reduce the cost of the composite cover plate 300. In one embodiment, the second light-transmitting member 44 has the same shape as the second through hole 34, so that the second light-transmitting member 44 can be installed in a seamless fit with the second through hole 34, and further, a sealing ring (not shown) is further disposed between the second light-transmitting member 44 and the second through hole 34 to perform a sealing and waterproof function, so as to prevent water or impurities from entering the second through hole 34 from an installation gap between the second light-transmitting member 44 and the second through hole 34 to affect the operation of the camera 10, or even damage the camera 10.
