The camera module 102 can enable the terminal 100 to implement functions such as image acquisition or instant video calls.

Please refer to FIG. 1 and FIG. 2 together. FIG. 2 is a schematic structural diagram of the terminal 100 provided in an embodiment of the present application in another working state. The camera module 102 includes a light turning component 1021. The light turning assembly 1021 may be fully or partially contained in the terminal body 101. As shown in FIG. 1, the light turning assembly 1021 is all contained in the terminal body 101. As shown in FIG. 2, the light turning assembly 1021 is partially housed in the terminal body 101.

Among them, the camera module 102 further includes a camera component 1022. The photographing component 1022 is housed in the terminal body 101. The photographing component 1022 and the light turning component 1021 together form a photographing module 102 to realize the photographing function.

Further, please refer to FIGS. 2 to 4 together. FIG. 3 is a structural diagram of the camera module 102 shown in FIG. 1 in the first state; FIG. 4 is the camera module 102 shown in FIG. 1 in the second state. Schematic diagram below. Among them, in the first state and the second state of the camera module 102, part or all of the light turning components 1021 are located outside the terminal body 101. At this time, the camera module 102 can be used for shooting.

The light turning assembly 1021 may be set at the first position or the second position. As shown in FIG. 3, the light turning assembly 1021 is set at the first position. As shown in FIG. 4, the light turning assembly 1021 is set at the second position. When the light turning assembly 1021 is set at the first position, it can realize the front-shooting function. When the light turning assembly 1021 is set in the second position, it can realize the rear camera function.

It is understandable that when the light turning assembly 1021 is in the first position and when the light turning assembly 1021 is in the second position, the position of the light turning assembly 1021 relative to the terminal body 101 remains unchanged, except that the image capturing surface of the light turning assembly 1021 is relative to the terminal body. 101 has changed. For example: when the user uses the terminal, when the light turning assembly 1021 is in the first position, the image collection surface of the light turning assembly 1021 faces the user, and the camera module 102 can be used as the front camera of the terminal 100; when the light turning assembly 1021 When in the second position, the image collection surface of the light steering assembly 1021 faces away from the user, and the camera module 102 can be used as a rear camera of the terminal 100 at this time.

In the embodiment of the present application, the light steering assembly 1021 may be set in different positions to realize the front-facing and rear-facing functions, so as to realize the switching of the front and rear cameras of the terminal 100. In the embodiment of the present application, the terminal 100 adopts the same camera by switching the position of the light steering component 1021, which can realize the function of the front camera and the function of the rear camera, thereby reducing the cost of the camera of the terminal 100.

Further, when the light turning assembly 1021 is set in the first position, the light turning assembly 1021 is partially housed in the terminal body 101, and the part of the light turning assembly 1021 that extends beyond the terminal body 101 can collect the light on the front surface of the terminal body 101.

As shown in FIG. 2, in the embodiment of the present application, part of the light turning assembly 1021 is housed in the terminal body 101 and part of the light turning assembly 1021 extends beyond the terminal body 101 for description. In other embodiments, the light turning assembly 1021 can also be fully contained in the terminal body 101. The orientation of the front surface of the terminal body 101 is the same as the orientation of the display screen of the terminal body. It can be understood that when the user uses the terminal body, the front surface of the terminal body faces the user, and the user can directly observe the front surface of the terminal body.

In the embodiment of the present application, the camera module 102 collects light through the part of the light steering component 1021 that exceeds the terminal body 101 to realize the front-shooting function, so that one or both sides of the terminal body 101 can all be arranged with display screens, which improves the terminal The screen-to-body ratio of the main body 101 can realize a full screen.

Further, when the light turning assembly 1021 is set in the second position, the light turning assembly 1021 is partially housed in the terminal body 101, and the part of the light turning assembly 1021 that extends beyond the terminal body 101 can collect the light on the rear surface of the terminal body 101. Realize the rear camera function.

Wherein, the front surface of the terminal body 101 and the rear surface of the terminal body 101 are disposed opposite to each other. It can be understood that the orientation of the rear surface of the terminal body 101 is opposite to the orientation of the display screen of the terminal body. When the user uses the terminal body, the rear surface of the terminal body is set opposite to the user, and the user cannot directly observe the rear surface of the terminal body.

In the embodiment of the present application, the camera module 102 collects light through the part of the light steering component 1021 that exceeds the terminal body 101 to realize the rear camera function, so that one or both sides of the terminal body 101 can all be arranged with display screens, which improves the terminal The screen-to-body ratio of the main body 101 can realize a full screen.

Please continue to refer to FIGS. 5 and 6. FIG. 5 is a schematic structural diagram of the camera module shown in FIG. 1 in a third state; FIG. 6 is a structural schematic diagram of the camera module shown in FIG. 5 at another angle. Among them, the camera module 102 is in the third state, and the camera module 102 is located inside the terminal body 101. The camera module 102 includes a circuit board 21, an image sensor (not marked in the figure), and a lens 22. It is understandable that the photographing component 1022 includes a circuit board 21, an image sensor, and a lens 22 to realize an imaging function. The image sensor is mounted on the circuit board 21. The lens 22 is located on the side of the image sensor away from the circuit board 21.

Among them, the circuit board 21 includes a rigid circuit board and a flexible circuit board. The image sensor is mounted on the rigid circuit board to ensure the stability of the image sensor and improve the reliability of the camera module 102. The flexible circuit board is used to electrically connect other components in the terminal 100. Since the flexible circuit board can be bent and deformed, the circuit board can be fixed to a required place through bending and deformation, which is beneficial to the arrangement of other remote devices of the terminal 100.

Further, please continue to refer to FIGS. 3 and 5, the light turning assembly 1021 includes a fixed portion 23, a light turning portion 24 and a moving portion 25. The light turning part 24 and the moving part 25 are attached to the fixed part 23. The light turning portion 24 is located on the side of the lens 22 away from the circuit board 21 and is arranged opposite to the lens 22 at intervals. Wherein, the light turning part 24 is used to obtain light from the outside to obtain a scene.

In the embodiment of the present application, external light enters the light redirecting part 24 from a first direction, and the light redirecting part 24 converts the light in the first direction into light in the second direction, and finally enters the lens 22. Wherein, the first direction is perpendicular to the second direction. For example, the first direction can be a horizontal direction, and the second direction is a vertical direction.

Further, please refer to FIGS. 3 to 7 together. FIG. 7 is a schematic structural diagram of the camera module shown in FIG. 4 from another angle. The moving part 25 is connected to the light turning part 24 for driving the light turning part 24 to move relative to the lens 22.

As shown in FIG. 5, when the light turning portion 24 is at the third position, the distance between the lens 22 and the light turning portion 24 is the first distance. At this time, the camera module 102 is located inside the terminal 100, and the terminal 100 does not need to use the camera module 102. It can be understood that when the light turning portion 24 is located in the third position, the light turning portion 24 is located in the terminal body 101.

As shown in FIG. 4, when the light turning portion 24 moves from the third position to the first position, the distance between the lens 22 and the light turning portion 24 is the second distance. The second distance is greater than the first distance. At this time, the light turning portion 24 of the camera module 102 is located outside the terminal 100, and the terminal 100 can use the camera module 102 to take pictures. It can be understood that when the light turning portion 24 is located at the first position, part or all of the light turning portion 24 is exposed to the terminal body 101.

When the light turning portion 24 is located at the first position, the light collected by the light turning portion 24 is reflected to the lens 22 to form an image on the image sensor. It is understandable that when imaging on the image sensor, the camera module 102 captures an image. When the light turning part 24 is located at the third position, the light turning part 24 is housed in the terminal 100. When the light turning part 24 moves from the third position to the first position, the light turning part 24 extends from the inside of the terminal 100 to the outside of the terminal 100. When the light turning part 24 is located outside the terminal 100, the light can be transmitted to the lens 22 through the light turning part 24, so that the camera module 102 can take pictures.

In the embodiment of the present application, the camera module 102 includes a light turning part 24, a moving part 25 and a lens 22. The light collected by the light turning portion 24 can be reflected to the lens 22 to form an image on the image sensor. The moving part 25 is used to drive the light turning part 24 to move relative to the lens 22 to prevent the circuit board 21 connected to the lens 22 from moving when the lens 22 moves, and the circuit board 21 is bent and deformed, thereby avoiding the electrical performance of the circuit board 21. The failure affects the imaging of the camera module 102.

Wherein, when the camera module 102 needs to take a picture, the moving part 25 drives the light turning part 24 to move up and framing. When the camera module 102 does not need to take a picture, the moving part 25 drives the light turning part 24 to move down, so that the light turning part 24 is retracted. The inside of the terminal 100, therefore, there is no need to provide a light-transmitting part for capturing the scene on the mobile phone, thereby increasing the screen-to-body ratio of the terminal 100.

In one embodiment, please continue to refer to FIG. 5 to FIG. 7, the light turning portion 24 is provided with a light transmitting portion 26. The light-transmitting part 26 is used to collect light. When the light turning portion 24 is located at the first position or the second position, the light entering through the light transmitting portion 26 is reflected by the light turning portion 24 to the lens 22.

In the embodiment of the present application, since the light turning portion 24 moves relative to the lens 22, the light turning portion 24 is provided with a light transmitting portion 26 for collecting light. The light passing through the light turning portion 26 is only reflected by the light turning portion 24 to the lens. After 22, the image is finally formed on the image sensor to avoid the situation that the circuit board 21 connected to the lens 22 is driven to move when the lens 22 moves, and the circuit board 21 is bent and deformed.

Further, the light turning part 24 includes a total reflection prism 241. The total reflection prism 241 has a first surface 2411 and a second surface 2412. The first surface 2411 is perpendicular to the second surface 2412. The total reflection prism 241 further includes a third surface 2413 connecting the first surface 2411 and the second surface 2412. The angles formed between the third surface 2413 and the first surface 2411 and the second surface 2412 are both 45 degrees. That is, the third surface 2413 is the hypotenuse of the total reflection prism 241.

As shown in FIGS. 5 and 6, the light turning portion 24 is located inside the fixing portion 23, that is, the light turning portion 24 is located inside the terminal body 101, and the camera module 102 does not need to take pictures at this time.

Further, please refer to FIG. 7 and FIG. 8 together. FIG. 8 is a partial structural diagram of the side surface of the camera module 102 shown in FIG. 7. As shown in FIG. 7, the light turning portion 24 is located outside the fixing portion 23, that is, the light turning portion 24 is located outside the terminal body 101, and the camera module 102 is used for taking pictures at this time.

In the embodiment of the present application, external light enters the first surface 2411 and then is reflected to the second surface 2412, or external light enters the second surface 2412 and is reflected to the first surface 2411, and finally enters the lens 22. After the light enters from one right-angled side of the total reflection prism 241, it is reflected on the third surface 2413, and is emitted from the other right-angled side of the total reflection prism 241.

As shown in FIG. 8, in an embodiment, after external light enters the first surface 2411 of the total reflection prism 241, it is reflected on the third surface 2413 and then exits from the second surface 2412, and finally enters the camera. In another embodiment, external light passes through the light-transmitting portion 26, enters the second surface 2412 of the total reflection prism 241, is reflected on the third surface 2413 and then exits the first surface 2411, and finally enters the camera. . That is, after external light enters one right-angle side of the total reflection prism 241, it is emitted from the other right-angle side of the total reflection prism 241.

In the embodiment of the present application, after external light enters from one right-angle side of the total reflection prism 241, the hypotenuse of the total reflection prism 241 can be all reflected to the other right-angle side of the total reflection prism 241, and finally all enter the lens. 22. It is avoided that external light enters from the hypotenuse of the total reflection prism 241, resulting in that only part of the light enters the lens 22 and affects the imaging quality of the camera module 102, thereby improving the utilization of light and improving the camera module 102 Reliability of imaging.

In one embodiment, please refer to FIGS. 3 and 7 to 10 together. FIG. 9 is a schematic structural view of the side of the camera module 102 shown in FIG. 3; FIG. 10 is a cross-section of the structure shown in FIG. 9 along line AA Schematic.

As shown in FIG. 3, the second surface 2412 of the total reflection prism 241 faces the other light-transmitting part 26 (for example, the second light-transmitting part 262 ), and the first surface 2411 of the total reflection prism 241 faces the lens 22. The light enters the total reflection prism 241 from the light-transmitting part 26 and finally enters the lens 22. As shown in FIG. 7, the first surface 2411 of the total reflection prism 241 faces a transparent portion 26 (for example, the first transparent portion 261 ), and the second surface 2412 of the total reflection prism 241 faces the lens 22. The light enters the total reflection prism 241 from the light-transmitting part 26 and finally enters the lens 22.

As shown in FIG. 10, the moving part 25 further includes a rotating member 251. The rotating member 251 is connected to the total reflection prism 241. The rotating member 251 drives the total reflection prism 241 to rotate to transform the first surface 2411 facing the lens 22 into a second surface 2412 facing the lens 22. Alternatively, the rotating member 251 drives the total reflection prism 241 to rotate to transform the second surface 2412 facing the lens 22 into the first surface 2411 facing the lens 22. As shown in FIG. 4 and FIG. 7, the second surface 2412 of the total reflection prism 241 faces the lens 22 (as shown in FIG. 7), and the total reflection prism 241 can face the first surface 2411 toward the lens 22 under the action of the rotating member 251 (as shown in FIG. 4).
