[0059] According to one embodiment of the present application, an electronic device 2 is proposed, comprising: a camera module 1 as described above, and therefore having all the beneficial effects of the camera module 1, which will not be repeated here.

[0060] According to some embodiments of the present application, optionally, the electronic device further includes: a frame 20; a display screen, covered on the frame 20, wherein the camera module 1 is arranged in the frame 20, and a through hole 200 is provided on the frame 20, and the through hole 200 is arranged opposite to the light-through hole 190; or the housing 19 of the camera module 1 is the frame 20 of the electronic device.

[0061] In this embodiment, the electronic device further includes a frame 20 and a display screen, and the display screen covers the frame 20 for displaying. Figure 10 、 Figure 11 and Figure 12 As shown, the camera module 1 is arranged in the frame 20, and the frame 20 is provided with a corresponding through hole 200, and the through hole 200 is arranged opposite to the light hole 190, thereby realizing the entry of light, that is, the camera module itself has a shell 19, so that the camera module is used as a component to facilitate the assembly of the electronic device; in another embodiment, as Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, or as Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the shell 19 of the camera module 1 is the frame 20 of the electronic device, that is, the shell 19 of the camera module 1 is used as the frame 20 of the electronic device, that is, the shell 19 of the camera module 1 and the frame 20 of the electronic device are the same, and accordingly, the through hole 200 and the light hole 190 are the same. When the camera module 1 is applied to the electronic device 2, the display screen is covered on the shell 19 to reduce the number of components.

[0062] Optionally, when the shell 19 of the camera module 1 is a frame 20 of an electronic device, the camera module 1 also includes a bracket, and the first prism 10, the lens group 12 and the second prism 14 are all arranged on the bracket, and at least one of the first prism 10 and the second prism 14 is rotatably connected to the bracket, so that the camera module 1 can constitute an assembly.

[0063] According to one embodiment of the present application, the present application replaces two separate periscopic cameras with two groups of lenses (the first lens group 120 and the second lens group 122) and prisms (for example, the first prism 10 and the second prism 14), a shared chip (for example, the photosensitive chip 16), and a circuit board, thereby reducing the size of the module. Optionally, by adjusting the positions of the lenses, the combination of different focal lengths can be achieved, and the prism above the chip (for example, the first prism 10) can be rotated to achieve the sharing of the same chip by the two groups of lenses, thereby being smaller in size than two periscopic cameras and achieving the switching of multiple zoom modes.

[0064] Optionally, the camera module 1 includes two groups of lenses (for example, the first lens group 120 and the second lens group 122), three prisms (for example, the first prism 10, the first sub-prism 140, and the second sub-prism 142), a common chip and circuit board, a bracket, and the like. The light-out prism (for example, the first prism 10) can be rotated by 90°. When not rotated, the light passes from the first sub-prism 140 to the light-out prism through the first lens group 120 to reach the chip for imaging, which is the zoom state. When the light-out prism is rotated by 90°, the light can reach the chip from the second sub-prism 142, the second lens group 122, and the light-out prism, thereby achieving the switching of different focal lengths.

[0065] The shapes, sizes, and lens spacings of the lenses in the first lens group 120 and the second lens group 122 are different, and the shapes and positions of the lenses need to be adjusted according to actual needs. Both the first lens group 120 and the second lens group 122 can be moved by a certain position (for example, driven by a coil and a magnet).

[0066] Embodiment of rotating the light-out prism: the two sides of the light-out prism are fixed with rotating shafts 180, and memory alloy wires (for example, memory alloy pieces 1820) are fixed on the upper and lower sides of the rotating shafts 180, respectively. The sizes of the memory alloy wires on the two sides are the same, and the memory alloy wires are not deformed when not powered, and the light-out prism does not rotate. When the memory alloy wires are powered, the lengths of the memory alloy wires are shortened, and the memory alloy wires on the two sides pull the rotating shafts 180 to rotate.

[0067] According to one embodiment of the present application, the prism above the chip (for example, the first prism 10) can be in a fixed state, and the light-in prism (for example, the second prism 14) can be rotated by 90°. Before rotation, it serves as a rear camera for shooting. After the second prism 14 is rotated, it serves as a front camera for shooting, and can achieve functions such as zoom and zoom macro. The embodiments proposed in the present application can share one periscopic camera for front and rear shooting. The front camera can also be equipped with a wide-angle camera, thereby having wide-angle and long-focus functions.

[0068] Optionally, the electronic device 2 includes a mobile phone, a tablet computer, a wearable device, a security device, and the like.
