[0042] Figure 1 is a schematic diagram of an exploded structure of an electronic device according to an exemplary embodiment. Figure 1As shown, the electronic device may include: a housing 1, a screen module 2, a camera module 3, a light transmission device 4 and other structures. An accommodating space is formed inside the housing 1, which can be used to assemble the camera module 3 or other unmentioned functional modules.

[0043] exist Figure 1 In the embodiment shown, the housing 1 includes a side frame 11 and a back plate 12; the side frame 11 may include a left side frame 111, a right side frame 112, a top side frame 113 and a bottom side frame (not shown in the figure), etc., to form a side structure of the electronic device. The back plate 12 is located on the back side (i.e. Figure 1 The left side shown), and the front side of the housing 1 (i.e. Figure 1 The right side of the housing 1 is open so that the housing 1 and the screen module 2 can be assembled together. In one embodiment, the back plate 12 and the side frame 11 can be an integral structure; in another embodiment, the back plate 12 and the side frame 11 can be a split structure so that the side frame 11 and the back plate 12 can be assembled together to form the housing 1.

[0044] In one embodiment, if Figure 1 The top side frame 113 shown may be provided with an opening 1130; in other embodiments, the opening 1130 may be opened in other side areas of the side frame 11 except the top side frame 113, such as the left side frame 111, the right side frame 112 or the bottom side frame, etc., and the present disclosure is not limited to this.

[0045] Figure 2 is a schematic diagram of a three-dimensional structure of a light transmission device according to an exemplary embodiment; Figure 3 FIG. 1 is a schematic diagram showing a light transmission device and a housing realizing relative movement according to an exemplary embodiment. Figure 2-3 As shown, the electronic device may include a bracket 5 , and the light transmission device 4 may be mounted on the bracket 5 , so that the light transmission device 4 can move synchronously with the bracket 5 , thereby achieving posture switching of the light transmission device 4 through the bracket 5 .

[0046] In one embodiment, the support 5 may include: Figure 2 The slider 50 shown in FIG. 1 , and the housing 1 may include (for example, specifically located on the top side frame 113 included in the housing 1) Figure 3 The slide rail 114 shown enables the bracket 5 to achieve relative sliding with the housing 1 through the cooperation between the slide rail 114 and the slider 50, and drives the light transmission structure 4 to form relative movement with the housing 1, thereby achieving the posture switching of the light transmission structure 4. In other embodiments, the bracket 5 can also achieve relative movement with the housing 1 in other ways, and the present disclosure is not limited to this.

[0047] Figure 4 FIG. 1 is a schematic diagram of a panel side of a light transmission device in a first posture according to an exemplary embodiment. Figure 4 As shown, when the light transmission device 4 is in the first posture, the camera module 3 is located inside the housing 1, and the light transmission device 4 extends from the housing 1 to transmit the light on the panel side to the camera module 3, so that the camera module 3 is implemented as a front camera. However, since the light transmission device 4, the camera module 3, etc. do not occupy any space of the screen module 2, it is helpful to obtain the largest possible screen-to-body ratio on the electronic device, and even form a full screen (that is, the panel side of the electronic device is completely or substantially completely covered by the display area of ​​the screen module 2).

[0048] Figure 5 FIG. 1 is a schematic diagram of a back panel side of a light transmission device in a first posture according to an exemplary embodiment. Figure 5 As shown, when the light conducting structure 4 (in Figure 5 When the light conducting structure 4 is in the first posture and is blocked by the bracket 5, the light conducting structure 4 can be moved out of the opening 1130 to the outside of the housing 1; for example, Figure 5 In the illustrated embodiment, the light conducting structure 4 is moved upward relative to the housing 1 so as to be moved out of the housing 1 .

[0049] In one embodiment, the back plate 12 of the housing 1 may be provided with a notch 120 communicating with the opening 1130; accordingly, the bracket 5 may include a bracket body 51 and a cover body 52. ​​The bracket body 51 is used to match the light transmission device 4 and the housing 1 respectively, for example, the bracket body 51 can be assembled with the light transmission device 4, and the bracket body 51 can form a relative slide with the housing 1; and the cover body 52 is used to match the notch 120 to open or close the notch 120.

[0050] Figure 6 According to an exemplary embodiment, a Figure 5 The cross-sectional view in the AA direction is shown. Figure 6 As shown, after the light transmission device 4 is moved out from the inside of the housing 1, the light on the panel side can be directed toward the light transmission device 4. For example, the incident direction of the light on the panel side is Figure 6 As shown, from right to left; and under the action of the light transmission device 4, the transmission direction of the light on the panel side can be changed, so that the light on the panel side changes from "from right to left" to "from top to bottom", so that the light on the panel side finally passes through the opening 1130 and is emitted to the lens of the camera module 3, so that the camera module 3 completes the shooting operation using the light on the panel side.

[0051] Then, by pointing the lens of the camera module 2 inside the shell 1 toward the opening 1130 (for example, from bottom to top), even if the screen module 2 does not have an opening adapted to the camera module 3 (in the relevant technology, the light on the panel side directly passes through the opening and is emitted to the lens of the camera module 3), the light on the panel side can still be collected by the light transmission device 4, and the camera module 3 is prompted to complete the shooting of the panel side, that is, the camera module 3 can realize the function of the "front camera" in the relevant technology.

[0052] In one embodiment, the light transmission device 4 may include a mirror. When the light transmission device 4 is in the first posture, Figure 6 As shown, the mirror can be oriented between the incident direction of the light on the panel side (horizontally, such as from right to left) and the lens direction of the camera module 3 (vertically, such as from bottom to top). For example, the mirror can be at an angle of 45° to the above-mentioned incident direction and lens direction, respectively, so that the light on the panel side can be transmitted to the lens of the camera module 3 by the mirror.

[0053] In another embodiment, the light transmission device 4 may include a right-angle prism, such as an isosceles right-angle prism, etc., which is not limited in the present disclosure. When the light transmission device 4 is in the first posture, such as Figure 6 As shown, the inclined surface of the right-angle prism is between the incident direction of the light on the panel side and the lens direction of the camera module 13. For example, the inclined surface can be at an angle of 45° to the above-mentioned incident direction and lens direction respectively, so as to transmit the light on the panel side to the lens of the camera module 3.

[0054] In other embodiments, the right-angle prism may also be assembled in other ways, and the inclined surface is not necessarily directed toward the light on the panel side and the light on the back panel side. For example, the first right-angle surface of the right-angle prism may be directed toward the light on the panel side and the light on the back panel side, so that the light on the panel side and the light on the back panel side can be incident on the inside of the right-angle prism from the first right-angle surface, reflected by the inclined surface to the second right-angle surface, and emitted from the second right-angle surface to the lens of the camera module 3.

[0055] Figure 7 FIG. 1 is a schematic diagram of a panel side of a light transmission device in a second posture according to an exemplary embodiment. Figure 7 As shown, when the light transmission device 4 is in the second posture, the light transmission device 4, the camera module 3, etc. are all located inside the housing 1, and the user can Figure 7 When viewed from the panel side as shown, only the screen module 2 etc. can be seen, that is, the light transmission device 4, the camera module 3 etc. will not occupy any space of the screen module 2, which helps to obtain the largest possible screen-to-body ratio, or even form a full screen.

[0056] Figure 8FIG. 1 is a schematic diagram of a back panel side of a light transmission device in a second posture according to an exemplary embodiment. Figure 8 As shown, when the light transmission device 4 is in the second posture, the bracket 5 can close the opening 1130; in one embodiment, the bracket body 51 of the bracket 5 can be adapted to the opening 1130 in terms of specifications, so that the bracket body 51 can just fill the gap formed by the opening 1130 on the side frame 11, and the cover body 52 can be adapted to the notch 120 on the back panel 12 in terms of specifications, so that the cover body 52 can just fill the gap formed by the notch 120 on the back panel 12, so that the side frame 11 and the back panel 12 can appear more integrated visually to ensure the overall aesthetics of the electronic device.

[0057] exist Figure 5-8 In the illustrated embodiment, corresponding to the opening 1130 and the notch 120 formed on the housing 1, the bracket 5 may be in an L-shaped structure, including a bracket body 51 located at the top and a cover body 52 located at the back panel side. In one case, the user may apply a first external force from bottom to top to the cover body 52, so that the cover body 52 may drive the bracket body 51 and the housing 1 to form a relative slide under the action of the first external force, so as to switch the light transmission device 4 to the first posture; in other words, the user may push the cover body 52 upward with a finger, so as to move the light transmission device 4 out of the interior of the housing 1, thereby achieving the light transmission function on the panel side. In another case, the user can apply a second external force from top to bottom to the bracket body 51, so that the bracket body 51 can drive the cover body 52 and the shell 1 to form a relative slide under the action of the second external force, so as to switch the light transmission device 4 to the second posture, and the bracket body 51 closes the opening 1130 and the cover body 52 closes the gap 120; in other words, the user can press the bracket body 51 downward with a finger to move the light transmission device 4 into the shell 1, that is, to retract the light transmission device 4.

[0058] Fig. 9 FIG. 1 is a schematic diagram showing a method for driving and controlling a light transmission device according to an exemplary embodiment. Fig. 9 As shown, the electronic device may include a driving device 6 such as a servo motor, and the driving device 6 may drive the light transmission device 4 to achieve posture switching. For example, the driving device 6 may directly drive the light transmission device 4 to enable the light transmission device 4 to achieve movement and posture switching; or, when the light transmission device 4 can move synchronously with other structures such as a bracket 5, the driving device 6 may also drive other structures such as the bracket 5 to drive the light transmission device 4 to achieve movement and posture switching.

[0059] The present disclosure can control the drive device 6 in a variety of ways. In one embodiment, the electronic device may include: Fig. 9The control device 7 shown, for example, may include a CPU inside an electronic device, etc., which is not limited by the present disclosure. The control device 7 may be connected to the driving device 6, and the control device 7 may send a first control command to the driving device 6 upon receiving a front camera activation instruction (such as a user triggering a physical button on the electronic device, enabling a software function on the electronic device, etc., which is not limited by the present disclosure), so that the driving device 6 drives the light transmission device 4 to a first posture, and the control device 7 may send a second control command to the driving device 6 upon receiving a camera shutdown instruction (such as a user triggering a physical button on the electronic device, enabling a software function on the electronic device, etc., which is not limited by the present disclosure), so that the driving device 6 drives the light transmission device 4 to a second posture.

[0060] In other embodiments, the driving device 6 may be controlled in other ways. For example, the electronic device may be configured with a function key (physical key or virtual key) for the driving device 6, and the user may trigger the function key to control the driving logic of the driving device 6 so that the driving device 6 drives the light transmission device 4 to achieve posture switching.

[0061] Fig.10 FIG. 1 is a schematic diagram of a three-dimensional structure of another light transmission device according to an exemplary embodiment. Fig.10 As shown, when the electronic device includes a bracket 5, the bracket 5 may include a sliding portion 5A and a rotating portion 5B. The sliding portion 5A may slide relative to the housing 1; for example, a slider 50 is provided on the sliding portion 5A. Figure 2-3 Similar to the illustrated embodiment, the slider 50 can cooperate with the slide rail 114 on the housing 1 so that the sliding portion 5A and the housing 1 can slide relative to each other.

[0062] The light transmission device 4 is fixedly mounted on the rotating portion 5B, and the rotating portion 5B is rotatably connected to the sliding portion 5A, so that the rotating portion 5B can slide relative to the housing 1 under the drive of the sliding portion 5A, and the rotating portion 5B further drives the light transmission device 4 to achieve relative movement with the housing 1, thereby prompting the light transmission device 4 to achieve posture switching between the first posture and the second posture.

[0063] In one embodiment, the interior of the sliding portion 5A may be formed as follows: Fig.10The accommodating space 501 shown in the figure can be used to accommodate the rotating part 5B; wherein, the side wall of the accommodating space 501 can include a circular hole 502, and the outer wall of the rotating part 5B can include a protrusion 503, so that the sliding part 5A and the rotating part 5B can achieve relative rotation under the cooperation between the circular hole 502 and the protrusion 503. Since the sliding part 5A and the housing 1 can only achieve relative sliding and no relative rotation, it is equivalent to the relative rotation between the light transmission device 4 and the housing 1.

[0064] When the light transmission device 4 is in the first posture, the rotating portion 5B can be rotated toward the panel side to a first angle, that is, the light transmission device 4 and the housing 1 are kept in a first posture. Figure 6 As shown in the relative position relationship, the light transmission device 4 can transmit the light on the panel side to the lens of the camera module 3, so that the camera module 3 is realized as a "front camera".

[0065] Fig.11 Another embodiment of the present invention is shown in FIG. Figure 5 The cross-sectional view in the AA direction is shown. Fig.11 As shown in FIG. 1 , when the light transmission device 4 is in the first posture, the rotating portion 5B can be rotated toward the back plate side to a second angle, that is, the light transmission device 4 and the housing 1 are kept as shown in FIG. Fig.11 As shown in the relative position relationship, the light transmission device 4 can transmit the light on the back panel side to the lens of the camera module 3, so that the camera module 3 is realized as a "rear camera".

[0066] In one embodiment, the user can apply a corresponding thrust to the rotating portion 5B to change the relative position relationship between the rotating portion 5B and the sliding portion 5A, and adjust the light transmission device 4 to the position as shown in FIG. Figure 6 or Fig.11 Status shown.

[0067] In one embodiment, if Fig. 9 The driving device 6 shown can be used to drive the rotation of the rotating part 5B. Similar to the above-mentioned embodiment, in one case, the driving device 6 can be driven and controlled by the control device 7, and in another case, the driving device 6 can be driven and controlled by the function keys on the electronic device, or other driving methods are used, which will not be described in detail here.

[0068] To sum up, the present invention improves the structure of the electronic device, such as by adopting structures such as light transmission devices, so that the camera module can at least realize the camera function of the front camera, and can avoid occupying the panel space of the screen module, which helps to increase the screen-to-body ratio of the electronic device and even realize a full screen.
