Electronic device

Abstract

The present application discloses an electronic device, which includes a housing and a front camera. Among them, the front camera can at least partially protrude outside the housing or be completely accommodated inside the housing. The front camera includes an image sensor and an optical component. The image sensor is disposed on the optical axis of the optical component. The optical component includes a light incident surface facing away from the image sensor. When the front camera at least partially protrudes outside the housing, the distance between the light incident surface and the image sensor is a first distance. When the front camera is completely accommodated inside the housing, the distance between the light incident surface and the image sensor is a second distance, and the second distance is less than the first distance. In this way, by enabling the front camera to partially protrude outside the housing and be completely accommodated inside the housing, and at the same time the distance between the light incident surface and the image sensor is adjustable, while increasing the screen-to-body ratio of the electronic device, a relatively large-sized image sensor can be used as much as possible to improve the imaging quality of the front camera.

Description

Technical Field

[0001] This application relates to the field of electronic devices, and in particular, to an electronic device. Background Art

[0002] An electronic device is generally provided with a front camera. In related technologies, due to the limitation of the thickness of the mobile phone, most of the front camera modules use fixed-focus cameras, and the size of the imaging sensor is small, resulting in limited imaging quality of the front camera. Summary of the Invention

[0003] An embodiment of this application provides an electronic device.

[0004] The electronic device provided by the embodiment of this application includes a housing and a front camera. The front camera can at least partially extend outside the housing or be completely accommodated inside the housing. The front camera includes an image sensor and an optical component. The image sensor is disposed on the optical axis of the optical component. The optical component includes a light incident surface facing away from the image sensor. When the front camera at least partially extends outside the housing, the distance between the light incident surface and the image sensor is a first distance. When the front camera is completely accommodated inside the housing, the distance between the light incident surface and the image sensor is a second distance, and the second distance is less than the first distance.

[0005] In this way, by enabling the front camera to partially extend outside the housing and be completely accommodated inside the housing, and at the same time by adjusting the distance between the light incident surface and the image sensor, it is possible to improve the screen-to-body ratio of the electronic device while solving the problem that the imaging quality of the front camera is affected by the limited size of the front camera due to the thickness limitation of the electronic device. Thus, an image sensor with a larger size can be used as much as possible to improve the imaging quality of the front camera.

[0038] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0039] Please refer to Figures 1 - 5, an embodiment of the present application provides an electronic device 1000. The electronic device 1000 includes a housing 100 and a front camera 200. The front camera 200 can at least partially extend outside the housing 100 or be completely accommodated inside the housing 100. The front camera 200 includes an image sensor 21 and an optical component 22. The image sensor 21 is disposed on the optical axis L1 of the optical component 22. The optical component 22 includes a light incident surface 220 facing away from the image sensor 21. When the front camera 200 at least partially extends outside the housing 100, the distance between the light incident surface 220 and the image sensor 21 is a first distance D1. When the front camera 200 is completely accommodated inside the housing 100, the distance between the light incident surface 220 and the image sensor 21 is a second distance D2, and the second distance D2 is less than the first distance D1 (as Figure 6 and Figure 7 shown).

[0040] In this way, by enabling the front camera 200 to partially extend outside the housing 100 and be completely accommodated inside the housing 100, and at the same time by adjusting the distance between the light incident surface 220 and the image sensor 21, it is possible to improve the screen-to-body ratio of the electronic device 1000 while solving the problem that the imaging quality of the front camera 200 is affected by the limited size of the front camera 200 due to the thickness limitation of the electronic device 1000. Thus, an image sensor 21 with a relatively large size can be used as much as possible to improve the imaging quality of the front camera 200.

[0041] Specifically, there are currently two technical solutions for the front camera 200 of existing electronic devices. The first is to place the front camera 200 inside the electronic device, and it is also inside the electronic device during the working state, and an opening is made on the screen for front imaging.

[0042] The second is to adopt an up-and-down telescopic mechanical structure (or a side telescopic mechanical structure). When the front camera 200 is working, the front camera 200 is extended from the inside of the electronic device for shooting. When the front camera 200 is not working, the front camera 200 is retracted into the inside of the electronic device. This solution can achieve a full-screen display of the electronic device.

[0043] However, no matter which of the above solutions, the front camera 200 is limited by the thickness of the electronic device, and the height dimension of itself is compressed. As a result, the front camera 200 can only use an image sensor 21 with a relatively small size to reduce its own height dimension, thereby affecting the imaging quality of the front camera 200.

[0044] In view of this, an electronic device 1000 is provided in the present application. The purpose is to make the overall height of the front camera 200 adjustable on the premise of ensuring the full-screen display and a certain thickness of the electronic device 1000, so that under the condition of ensuring the reasonable height dimension of the front camera 200, an image sensor 21 with a larger size can be used as much as possible to improve the imaging quality.

[0045] For the convenience of description, a mobile phone can be used as a specific example of the electronic device 1000 in the embodiment of the present application for description. It can be understood that in addition to mobile phones, the electronic device 1000 can also be other devices equipped with a front camera 200, such as tablet computers, e-book readers, MP3 players, MP4 players, in-vehicle computers, desktop computers, smart TVs, or wearable devices, etc.

[0046] Then, in order to ensure a certain thickness of the electronic device 1000 and improve the imaging effect of the front camera 200, the front camera 200 in the present application includes an image sensor 21 and an optical component 22. In this way, by setting the distance from the light incident surface 220 of the optical component 22 facing away from the image sensor 21 to the image sensor 21 to be adjustable, the height dimension of the front camera 200 when the front camera 200 is disposed inside the electronic device 1000 can be compressed. Further, as Figure 4 and Figure 5 shown, only when there is a shooting requirement, the front camera 200 can be at least partially extended outside the housing 100 so that the distance between the light incident surface 220 and the image sensor 21 is increased to meet the shooting requirement, so that the front camera 200 can provide users with better photo and video shooting effects.

[0047] Specifically, the housing 100 can be made of materials such as metal or plastic. The housing 100 can be used to accommodate the image sensor 21, the optical component 22, etc. It can be understood that, as Figures 2 - 5 shown, an avoidance hole 13 can be formed on the housing 100. When the front camera 200 moves in a direction perpendicular to the optical axis L1, it can extend outside the housing 100 or retract into the housing 100 through the avoidance hole 13.

[0048] As Figures 6 - 9 shown, the image sensor 21 is disposed on the optical axis L1 of the optical component 22. The optical component 22 can include a lens group for imaging. The optical component 22 includes a light incident surface 220 facing away from the image sensor 21. As Figures 4 - 6 shown, when the front camera 200 is in a working state, the front camera 200 is at least partially extended outside the housing 100. At this time, the distance between the light incident surface 220 and the image sensor 21 is the first distance D1; as Figures 2 - 3 、 Figure 7When the front camera 200 is not in use, the front camera 200 can be completely accommodated in the housing 100. At this time, the distance between the light incident surface 220 and the image sensor 21 is the second distance D2, and the second distance D2 is less than the first distance D1.

[0049] It can be understood that in order to meet the camera requirements and improve the camera quality, it is possible to choose to increase the size of the image sensor 21 or use a lens with higher resolution and larger aperture. However, the longer the optical total length of the lens paired with the larger-sized image sensor 21, the greater the height dimension of the front camera 200, and thus the thickness dimension of the electronic device 1000 will also increase. In the first embodiment of the present application, by making the front camera 200 of the electronic device 1000 movable relative to the housing 100 so as to at least partially extend out of the housing 100 or be completely accommodated in the housing 100, after the front camera 200 extends out of the housing 100, the distance from the light incident surface 220 to the image sensor 21 is increased, so that a large-sized image sensor 21 can be used while ensuring a certain thickness of the electronic device 1000, and the shooting quality of the front camera 200 is ensured.

[0050] Please refer to Figures 2 - 5 , and Figure 10 , in some embodiments, the electronic device 1000 may include a first driving mechanism 300. The first driving mechanism 300 is used to drive the front camera 200 to extend out of the housing 100 or retract into the housing 100 along a predetermined direction, and the predetermined direction is perpendicular to the optical axis L1. In this way, making the predetermined direction in which the first driving mechanism 300 drives the front camera 200 to move perpendicular to the optical axis L1 can achieve the anti-shake function.

[0051] Specifically, the first driving mechanism 300 may be in the form of a lead screw motor drive, a belt drive, a gear and rack drive, etc. The present application embodiment does not impose a fixed limit on the specific transmission method of the first driving mechanism 300. As long as the first driving mechanism 300 can drive the front camera 200 to move in a direction perpendicular to the optical axis L1 so that the front camera 200 can extend out of the housing 100 or retract into the housing 100 in a direction perpendicular to the optical axis L1.

[0052] Thus, when the user needs to use the front camera 200 for shooting, the first driving mechanism 300 can first pop out the entire module of the front camera 200 out of the housing 100, and then adjust the specific positions of the optical component 22 and the image sensor 21 after popping out of the housing 100 to obtain a better shooting effect. At this time, it can be understood that the first driving mechanism 300 is mainly used to drive the front camera 200 to extend and retract on the plane of the electronic device 1000, so as to realize the state conversion of the front camera 200 inside and outside the electronic device 1000 (that is, inside and outside the housing 100). That is to say, at this time, the predetermined direction can be any angular direction in the plane where the electronic device 1000 is located. For example, it can extend along the length direction or the width direction of the electronic device 1000, as long as the predetermined direction is perpendicular to the optical axis L1 to achieve the anti-shake function.

[0053] Please refer to Figure 10 , in some embodiments, the first driving mechanism 300 may include a bracket 31 and a driving component 32. The bracket 31 can be connected to the driving component 32, the front camera 200 can be installed on the bracket 31, and the driving component 32 can drive the bracket 31 to move relative to the housing 100, so as to drive the front camera 200 to extend out of the housing 100 or retract into the housing 100.

[0054] In this way, setting the bracket 31 can install the front camera 200 on the bracket 31 so that the front camera 200 and the bracket 31 form a structurally compact whole, and thus the front camera 200 can be driven to move relative to the housing 100 by driving the bracket 31 to move.

[0055] Specifically, the bracket 31 can be a plastic part or a metal part such as an alloy part. A positioning groove 310 can be formed on the bracket 31 for rigidly fixing structures such as the front camera 200. The bracket 31 can include a top plate 311 and a bottom plate 312. In the state where the front camera 200 is completely accommodated in the housing 100, the top plate 311 of the bracket 31 is flush with the surface of the housing 100, or in other words, the top plate 311 of the bracket 31 seals the avoidance hole 13 on the housing 100.

[0056] The driving assembly 32 can be connected to the bracket 31. Specifically, the driving assembly 32 can include a driving motor 320 and a transmission assembly 321. The driving motor 320 can be a stepping motor. The transmission assembly 321 can include a screw 3210 and a nut 3211. The driving assembly 32 can also include a speed reducer 3212, such as a harmonic speed reducer 3212. Among them, the driving motor 320 can be fixedly installed on the housing 100. The nut 3211 can be installed on the lower surface of the bottom plate 312. Mounting holes 3120 can be formed on the bottom plate 312. The screw 3210 can pass through the bottom plate 312 through the mounting holes 3120 and pass through the nut 3211. Thus, the housing 100, the driving assembly 32, the bracket 31 and the front camera 200 form a structurally compact whole.

[0057] In this way, the driving motor 320 can drive the screw 3210 to rotate through the speed reducer 3212. The nut 3211 is rigidly fixed on the bottom plate 312 and rotates with the screw 3210. Thus, the nut 3211 drives the bracket 31 to move relative to the housing 100 in a predetermined direction, thereby driving the front camera 200 to extend out of the housing 100 or retract into the housing 100. It can be understood that arranging the bracket 31 to mount the front camera 200 can make the movement of the front camera 200 more stable, and the bracket 31 can provide a supporting effect for the front camera 200.

[0058] Please refer to Figure 10 , in some embodiments, the first driving mechanism 300 can further include a guiding assembly 33. The guiding assembly 33 can connect the housing 100 and the bracket 31. The guiding assembly 33 can be used to guide the movement of the bracket 31. In this way, the guiding assembly 33 connects the housing 100 and the bracket 31, so that the guiding assembly 33, the housing 100 and the bracket 31 form a structurally compact whole; the setting of the guiding assembly 33 can provide a guiding effect for the movement of the bracket 31 relative to the housing 100, and at the same time make the movement of the bracket 31 relative to the housing 100 more stable.

[0059] Please refer to Figure 10 , in some embodiments, the guiding assembly 33 can include a mounting base 330 and a guide rod 331. The mounting base 330 can connect the housing 100. One end of the guide rod 331 can be connected to the mounting base 330. The guide rod 331 can be inserted into the bracket 31, and the bracket 31 can move relative to the guide rod 331. In this way, the guiding assembly 33 is connected to the housing 100 through the mounting base 330 and connected to the bracket 31 through the guide rod 331. Thus, the guiding assembly 33 is arranged on the housing 100 and provides a stable guiding effect for the bracket 31 through the guide rod 331, with a simple structure and a reliable guiding effect.

[0060] Specifically, it can be understood that if the guiding component 33 is not provided and only the driving component 32 is used to drive the bracket 31 to move relative to the housing 100, the movement of the bracket 31 will be unstable. The guiding component 33 in this application may include a mounting base 330 and a guide rod 331. The mounting base 330 can be in various regular or irregular shapes such as circular, oval, polygonal, etc. The mounting base 330 can be used as a base for fixing the guide rod 331 and is fixed within the housing 100. The guide rod 331 can be inserted through the mounting hole 3120 on the bracket 31 onto the bottom plate 312 of the bracket 31 and fixed to the mounting base 330 through the fixing hole 3300 on the mounting base 330. The bracket 31 can move relative to the guide rod 331 under the action of the driving component 32. The guide rod 331 can provide a guiding function for the movement of the bracket 31 relative to the housing 100, and at the same time make the movement of the bracket 31 relative to the housing 100 more stable.

[0061] Please refer to Figure 9 , in some embodiments, the electronic device 1000 may include a second driving mechanism 400. The second driving mechanism 400 can be used to drive at least part of the optical component 22 to move along the optical axis L1 to adjust the distance between the light incident surface 220 and the image sensor 21. In this way, the imaging quality of the front camera 200 can be improved without affecting the thickness of the electronic device 1000.

[0062] Specifically, the second driving mechanism 400 can be used to drive at least part of the optical component 22 to move along the optical axis L1. In this way, in the first embodiment of this application, the front camera 200 can be driven by the first driving mechanism 300 to extend and retract on the plane of the electronic device 1000, so as to realize the state conversion of the front camera 200 inside and outside the electronic device 1000 (that is, inside and outside the housing 100). The second driving mechanism 400 can be used to drive the front camera 200 to extend and retract along the optical axis L1, that is, to extend and retract perpendicular to the plane of the electronic device 1000. In this way, the distance between the optical component 22 and the image sensor 21 can be adjusted.

[0063] The second driving mechanism 400 can be driven in the form of a spring and a fitting, or can be controlled by a stepper motor and a gearbox, or can be realized by a large-stroke autofocus motor. The specific implementation form of the second driving mechanism 400 is not limited in this application embodiment.

[0064] It can be easily understood that in the first embodiment of the present application, the front camera 200 is ejected out of the housing 100 by the first driving mechanism 300, and then the distance between the light incident surface 220 and the image sensor 21 is adjusted by the second driving mechanism 400. In this way, when a large-sized image sensor 21 is used to improve the imaging effect of the front camera 200, the overall height of the front camera 200 inside the housing 100 will not be increased, thus increasing the overall thickness of the electronic device 1000. In this way, the height dimension of the front camera 200 can be compressed when the front camera 200 is arranged inside the electronic device 1000 to avoid affecting the thickness of the electronic device 1000, and the imaging quality of the front camera 200 can also be improved.

[0065] In some embodiments, the second driving mechanism 400 can be configured to drive at least a part of the optical components 22 to move away from the image sensor 21 along the optical axis L1 during the process that the first driving mechanism 300 drives the front camera 200 to extend out of the housing 100. Thus, in the first embodiment, the second driving mechanism 400 and the first driving mechanism 300 can work simultaneously, so that during the process that the first driving mechanism 300 drives the front camera 200 to extend out of the housing 100, the second driving mechanism 400 can drive at least a part of the optical components 22 to move away from the image sensor 21 along the optical axis L1. In this way, when there is a need to use the front camera 200, the front camera 200 can be adjusted to a suitable imaging position more quickly, improving the shooting efficiency and the user experience.

[0066] Please refer to Figure 9 、 Figure 11 and Figure 12 In some embodiments, the front camera 200 may include a substrate 23, the image sensor 21 is disposed on the substrate 23, and the second driving mechanism 400 is connected to the optical components 22 and the substrate 23. Thus, the image sensor 21 can be fixed on the bracket 31 through the substrate 23, and the second driving mechanism 400 is connected to the optical components 22 and the substrate 23, so that the second driving mechanism 400 can drive at least a part of the optical components 22 to move away from or close to the substrate 23 along the optical axis L1.

[0067] Specifically, the substrate 23 can be fixed in the positioning groove 310 of the bracket 31, and the image sensor 21 is disposed on the substrate 23. For example, it can be adhered to the substrate 23 or installed on the substrate 23 by other fixing means. The second driving mechanism 400 can be connected to the optical components 22 and the substrate 23, so that the second driving mechanism 400 can drive at least a part of the optical components 22 to move away from or close to the substrate 23 along the optical axis L1.

[0068] Please refer to Figure 9 、 Figure 11 andFigure 12 , in some embodiments, the optical component 22 includes a lens barrel 221 and a first lens group 223 disposed within the lens barrel 221. The first lens group 223 includes an incident light surface 220. The second driving mechanism 400 connects the lens barrel 221 and the substrate 23.

[0069] Specifically, the first lens group 223 can be used to collect external optical signals, and the lens barrel 221 can protect the first lens group 223. The substrate 23 can be fixed in the positioning groove 310 of the bracket 31, and the image sensor 21 is disposed on the substrate 23. Since the second driving mechanism 400 connects the lens barrel 221 and the substrate 23, the second driving mechanism 400 can drive the lens barrel 221 to move away from or close to the substrate 23 along the optical axis L1. The lens barrel 221 can protect the first lens group 223 disposed within it, and at the same time, the first lens group 223 is driven to move away from or close to the substrate 23 along the optical axis L1 to move to a suitable position for a better imaging effect.

[0070] Please refer to Figure 9 , Figure 11 and Figure 12 , in some embodiments, the optical component 22 may further include a second lens group 224. The second lens group 224 is coaxially disposed with the first lens group 223. The second lens group 224 is disposed between the image sensor 21 and the first lens group 223, and the second lens group 224 remains fixed relative to the image sensor 21. Specifically, the first lens group 223 and the second lens group 224 are used for imaging. In the first embodiment, when the second driving mechanism 400 operates, the first lens group 223 moves along the optical axis L1 relative to the second lens group 224 and the image sensor 21, and the second lens group 224 remains fixed. Of course, in some other embodiments, only the image sensor 21 may be disposed on the substrate 23 and remain fixed, and the second driving mechanism 400 drives the first lens group 223 and the second lens group 224 to move together.

[0071] Please refer to Figure 9 , Figure 11 and Figure 12, in some embodiments, the second driving mechanism 400 may include an elastic member 41. The elastic member 41 may be connected to the lens barrel 221, and the elastic member 41 provides a force for the lens barrel 221 to move in a direction away from the image sensor 21. In this way, after the front camera 200 pops out of the housing 100, the distance between the lens barrel 221 and the image sensor 21 can be adjusted by the elastic member 41, that is, the distance between the first lens group 223 and the image sensor 21 can be adjusted; at the same time, the elastic member 41 can also enable the front camera 200 to be retracted into the housing 100. When the front camera 200 is retracted into the housing 100, the height dimension of the front camera 200 can be compressed through the cooperation of the elastic member 41 and other components, so as not to affect the thin and light design of the electronic device 1000.

[0072] Specifically, the elastic member 41 may be a spiral spring, and the central axis of the elastic member 41 coincides with the optical axis L1. One end of the elastic member 41 is rigidly fixed to the substrate 23, and the other end of the elastic member 41 is fixed in the accommodation groove formed by the lens barrel 221 facing the elastic member 41. When the front camera 200 is completely accommodated in the housing 100, the elastic member 41 is in a compressed state; during the process of the first driving mechanism 300 driving the front camera 200 to extend out of the housing 100, when the second driving mechanism 400 drives at least part of the optical components 22 to move in a direction away from the image sensor 21 along the optical axis L1, the elastic member 41 gradually changes from a compressed state to a relaxed state to provide a force for the lens barrel 221 to move in a direction away from the image sensor 21.

[0073] In addition, the second driving mechanism 400 further includes a guiding member 42. The guiding member 42 may be multiple guiding columns. In the first embodiment, the three guiding members 42 are distributed in an equilateral triangle, and the center surrounded by the three guiding members 42 coincides with the optical axis L1. The guiding member 42 can be inserted on the lens barrel 221, so that when the lens barrel 221 moves along the optical axis L1 in a direction away from or close to the image sensor 21, the guiding member 42 can guide the movement of the lens barrel 221.

[0074] Please refer to Figure 9 、 Figure 11 And Figure 12 , in some embodiments, a first fitting 2211 may be provided on the lens barrel 221, and a second fitting 14 may be provided on the housing 100. During the process of the first driving mechanism 300 driving the front camera 200 to extend out of the housing 100, the lens barrel 221 gradually moves in a direction away from the image sensor 21 under the action of the force and the first fitting 2211 and the second fitting 14.

[0075] Specifically, in the first embodiment, the lens barrel 221 may include a connected first part 225 and a second part 226, wherein the diameter of the second part 226 is greater than that of the first part 225, and the first part 225 is disposed on the surface of the second part 226 to form a stepped structure. The first part 225 and the second part 226 may be annular, and the first lens group 223 may be disposed on the first part 225.

[0076] The first fitting 2211 may be annular, concentric with the lens barrel 221, and the first fitting 2211 may be disposed on the second part 226 and surround the first part 225. The first fitting 2211 may be rigidly fixed on the upper surface of the second part 226, or the first fitting 2211 may be directly formed during the machining of the lens barrel 221, so that the first fitting 2211 and the lens barrel 221 are integrally formed.

[0077] The second fitting 14 may be in the shape of a cam, and the second fitting 14 may have an inclined surface or an inclined curved surface. The second fitting 14 may be fixedly connected to the housing 100, such as being welded or adhesively fixed inside the housing 100. In the first embodiment, when the front camera 200 is completely accommodated in the housing 100, the second fitting 14 and the first fitting 2211 may abut against each other, so that the second fitting 14 can cooperate to compress the gap between the lens barrel 221 and the image sensor 21, reducing the size of the front camera 200; when the front camera 200 extends out of the housing 100 along a predetermined direction perpendicular to the optical axis L1, the first fitting 2211 moves along the predetermined direction to move away from the second fitting 14, so that the lens barrel 221 gradually moves away from the image sensor 21 under the action of the force and the first fitting 2211 and the second fitting 14, until when the front camera 200 is completely ejected out of the housing 100 as a whole, the lens barrel 221 also moves to the working position along the optical axis L1, and the end of the second fitting 14 may abut against the first fitting 2211.

[0078] In addition, please refer to Figure 8 、 Figure 11 and Figure 12, in some embodiments, the lens barrel 221 may have a light incident port 2212, and the first fitting 2211 protrudes from the light incident port 2212 along the direction of the optical axis L1. It can be understood that the light incident port 2212 of the lens barrel 221 can collect external light and facilitate the photosensitivity of the image sensor 21. At this time, the first fitting 2211 is disposed on the second part 226 and surrounds the first part 225. Since the first lens group 223 can be disposed on the first part 225, in order to protect the first part 225 of the lens barrel 221 when adjusting the distance between the first lens group 223, that is, between the lens barrel 221 and the image sensor 21, and to prevent the second fitting 14 from interfering with the first part 225 of the lens barrel 221, the first fitting 2211 can protrude from the light incident port 2212 along the direction of the optical axis L1.

[0079] Please refer to Figure 11 and Figure 12 , in some embodiments, the second fitting 14 may include a mating surface 140 facing the image sensor 21. Along the direction in which the front camera 200 extends out of the housing 100, the distance H between the mating surface 140 and the image sensor 21 gradually increases, and the first fitting 2211 can abut against the mating surface 140.

[0080] In this way, when the first driving mechanism 300 drives the front camera 200 to retract into the housing 100, the first fitting 2211 can cooperate with the second fitting 14 to move the lens barrel 221 of the front camera 200 along the optical axis L1 towards the image sensor 21, so as to compress the thickness dimension of the front camera 200, and further enable the front camera 200 to be completely retracted into the housing 100.

[0081] Specifically, the mating surface 140 of the second fitting 14 facing the image sensor 21 can be an inclined surface or an inclined curved surface. Along the direction in which the front camera 200 extends out of the housing 100, the distance between the mating surface 140 and the image sensor 21 gradually increases. In the first embodiment, as Figure 7 and Figure 11 shown, when the front camera 200 is completely accommodated in the housing 100, the distance H between the mating surface 140 and the image sensor 21 is the smallest, the distance between the light incident surface 220 and the image sensor 21 is the first distance D1, and at this time the elastic member 41 is in a compressed state. The second fitting 14 cooperates with the first fitting 2211 to compress the gap between the lens barrel 221 and the image sensor 21, reducing the size of the front camera 200.

[0082] As Figure 6 and Figure 12As shown, after the front camera 200 is turned on, the first driving mechanism 300 operates to drive the bracket 31 to drive the front camera 200 to extend out of the housing 100 along a predetermined direction perpendicular to the optical axis L1. During the pop-up process, since the distance H between the mating surface 140 of the second mating member 14 and the image sensor 21 gradually increases, that is, the thickness of the second mating member 14 in the direction of the optical axis L1 gradually decreases, space is created for the lens barrel 221 to move along the optical axis L1 away from the image sensor 21. Furthermore, under the action of the force, the first mating member 2211 and the second mating member 14, the lens barrel 221 moves along the optical axis L1 in the direction away from the image sensor 21 until the front camera 200 is completely popped out of the housing 100, and at the same time, the lens barrel 221 also moves to a suitable position, and the front camera 200 starts to work.

[0083] When the front camera 200 is turned off, the first driving mechanism 300 operates to drive the entire front camera 200 to retract into the housing 100 along a predetermined direction perpendicular to the optical axis L1. During the retraction, since the thickness of the second mating member 14 in the direction of the optical axis L1 gradually increases, that is, the distance H between the mating surface 140 and the image sensor 21 gradually decreases, thereby realizing that in the direction of the optical axis L1, the second mating member 14 compresses the lens barrel 221 provided with the first mating member 2211 downward, reducing the height of the front camera 200 itself, so that the front camera 200 can be retracted into the housing 100.

[0084] Please refer to Figure 9 , in some embodiments, the front camera 200 may further include a housing 24. The housing 24 may be rectangular. The lens barrel 221, the first lens group 223, the second lens group 224, and the image sensor 21 may be installed in the housing 24, and the housing 24 may be connected to the substrate 23. The housing 24 can protect the image sensor 21, the first lens group 223, and the second lens group 224. In addition, the housing 24 may include a limiting surface away from the image sensor 21. When the lens barrel 221 pops out along the optical axis L1 in the direction away from the image sensor 21, the limiting surface can limit the further pop-up of the lens barrel 221.

[0085] Specifically, in one embodiment, the front camera 200 may be provided with a large-stroke autofocus motor to realize the movement of the lens barrel 221 relative to the image sensor 21. At the same time, the front camera 200 may have autofocus and optical image stabilization functions, so as to ensure that after adjusting the distance between some optical components 22 and the light incident surface 220, the optical components 22 can have a better and more stable imaging effect. As follows Figure 13 As shown, the large working stroke of the autofocus motor of the front camera 200 can be divided into two strokes, and the purposes of the two strokes are different.

[0086] Among them, Stroke 1 belongs to the telescopic stroke along the optical axis L1. The purpose is to reduce the height of the entire module when the front camera 200 is closed, so that the front camera 200 can be retracted into the housing 100 of the electronic device 1000; Stroke 2 belongs to the autofocus stroke of the front camera 200.

[0087] After the front camera 200 is turned on, the first driving mechanism 300 drives the front camera 200 to pop out of the electronic device 1000 along a predetermined direction. After the popping is completed, the large-stroke autofocus motor of the front camera 200 works, driving the lens barrel 221 to move to the vertex C of Stroke 1. Then, autofocus is performed using Stroke 2 according to the imaging clarity of the front camera 200.

[0088] After the front camera 200 is turned off, the large-stroke autofocus motor of the front camera 200 first works, driving the lens barrel 221 to move to the bottom point of Stroke 2 (i.e., the vertex of Stroke 1) C. Then, it continues to move along the optical axis L1 towards the image sensor 21 until it reaches the zero point D of the full stroke of the autofocus motor. Then, the first driving mechanism 300 drives the front camera 200 to retract into the electronic device 1000 along a predetermined direction.

[0089] In some embodiments, the electronic device 1000 includes a display screen covering the front camera 200. The front camera 200 collects images through the display screen, and the image sensor 21 can move relative to the display screen along the optical axis L1 to adjust the distance between the light incident surface 220 and the image sensor 21.

[0090] In this way, a full-screen display effect of the electronic device 1000 can be achieved. At the same time, the image sensor 21 can move relative to the display screen along the optical axis L1 to adjust the distance between the light incident surface 220 and the image sensor 21, so that the imaging quality of the front camera 200 can be improved on the premise of meeting the thin and light requirements of the electronic device 1000.

[0091] Specifically, in the above-mentioned Embodiment 1, the front camera 200 can pop out at the top or side of the housing 100, and then the lens barrel 221 can move relative to the image sensor 21 along the optical axis L1 in a direction away from the image sensor 21 to adjust the distance from the light incident surface 220 to the image sensor 21, so as to meet the imaging conditions of the front camera 200 using a large-size image sensor 21.

[0092] In addition, as Figures 14 - 16As shown, in the second embodiment, the implementation manner of the present application can also adjust the distance between the light incident surface 220 and the image sensor 21 by moving the image sensor 21 relative to the display screen along the optical axis L1. At this time, the height of the front camera 200 itself can be adjusted according to whether the front camera 200 is in the on state or the off state, so as to achieve the purpose of reducing the height of the front camera 200 in the off state, and it can also be used for zooming of the front camera 200. For the front camera 200 in the second embodiment, since the front camera 200 is on the screen side and the screen cannot be opened for the front camera 200 to perform telescopic movement, the telescopic movement of the front camera 200 can be set to move relative to the display screen.

[0093] Please refer to Figures 14 - 17 , in some implementation manners, the light incident surface 220 can be fixed relative to the display screen, and the electronic device 1000 can include a first driving structure 500, and the first driving structure 500 can be used to drive the image sensor 21 to extend out of the housing 100 or retract into the housing 100. In this way, on the premise of meeting the thin and light requirements of the electronic device 1000, full-screen display of the electronic device 1000 can be achieved, and the imaging quality of the front camera 200 can be improved.

[0094] Specifically, the first driving structure 500 can be in the form of a lead screw motor drive, a belt drive, a gear and rack drive, etc. The present application implementation manner does not make a fixed limitation on the specific transmission manner of the first driving structure 500. As long as the first driving structure 500 can drive the image sensor 21 to move along the optical axis L1 to extend out of the housing 100 or retract into the housing 100. It should be noted that the housing 100 in the second embodiment can include the battery back cover 12 of the electronic device 1000.

[0095] In this way, when the user needs to use the front camera 200 for shooting, the first driving structure 500 drives the image sensor 21 to extend out of the housing 100 to adjust the distance between the image sensor 21 and the light incident surface 220, so that the distance from the light incident surface 220 to the image sensor 21 increases. Thus, it is possible to use a large-size image sensor 21 while ensuring a certain thickness of the electronic device 1000, and ensure the shooting quality of the front camera 200.

[0096] Please refer to Figure 17, in some embodiments, the front camera 200 includes a substrate 23 and a housing 25 connected to the substrate 23. The image sensor 21 is disposed on the substrate 23. The first driving structure 500 is configured to drive the housing 25 to move, so as to drive the substrate 23 to extend out of the housing 100 or retract into the housing 100. In this way, the housing 25 can protect the image sensor 21 disposed on the substrate 23, such that when the first driving structure 500 drives the housing 25 to move to drive the substrate 23 to extend out of the housing 100, the image sensor 21 is covered by the housing 25.

[0097] Specifically, the substrate 23 can be provided to mount the image sensor 21 thereon, such that the image sensor 21 and the substrate 23 form a structurally compact whole. The housing 25 is connected to the substrate 23, such that the housing 25, the substrate 23 and the image sensor 21 form a structurally compact whole. The housing 25 can protect the image sensor 21, and the image sensor 21 on the substrate 23 can be driven to move relative to the housing 100 by driving the housing 25 to move.

[0098] Specifically, the substrate 23 can be bonded or welded to the housing 25. The substrate 23 can be rectangular. The outer contour of the housing 25 can be in the shape of a cube or a cuboid. The housing 25 and the substrate 23 can be plastic parts or metal parts such as alloy parts. The image sensor 21 can be bonded to the substrate 23 or mounted on the substrate 23 by other fixing means. The first driving structure 500 can be mounted inside the housing 100 and connected to the housing 25. In the second embodiment, the housing 100 can include a rear cover 12, and a through hole 120 is formed on the rear cover 12, so that under the drive of the first driving structure 500, the housing 25 can drive the substrate 23 to extend out of the rear cover 12 through the through hole 120.

[0099] At this time, it can be understood that in the state where the front camera 200 is completely accommodated in the housing 100, the outer surface of the substrate 23 can be used as part of the appearance of the electronic device 1000. Then the substrate 23 and the housing 100 can be made of the same material, such that the overall appearance of the electronic device 1000 is more consistent and beautiful. In particular, in the state where the front camera 200 is completely accommodated in the housing 100, the outer surface of the substrate 23 can be flush with the outer surface of the rear cover 12. The top plate 311 of the substrate 23 being flush with the surface of the housing 100 can make the electronic device 1000 relatively flat and beautiful.

[0100] Please refer to Figure 17 and Figure 18, in some embodiments, the optical component 22 includes a lens barrel 221 and a lens group 222 disposed within the lens barrel 221. The lens group 222 includes an incident light surface 220. The lens barrel 221 is at least partially disposed within the housing 25, and the housing 25 is movable relative to the lens barrel 221. The lens barrel 221 can be fixed to the chassis 100 through a mounting member 26. Thus, the lens barrel 221 can provide a certain degree of protection for the lens group 222 disposed therein.

[0101] Specifically, a through hole 250 can be formed on the housing 25. The through hole 250 can be used to provide an avoidance space 71 for the lens barrel 221 when the housing 25 is driven by the first driving structure 500 to move relative to the lens barrel 221. The lens group 222 within the lens barrel 221 can be used to collect external light for subsequent imaging. The lens barrel 221 can be fixed to the chassis 100 through the mounting member 26. In the case where the chassis 100 includes a middle frame 11, the lens barrel 221 can be mounted on the middle frame 11 of the chassis 100 through the mounting member 26. In this way, when the first driving structure 500 operates, the lens barrel 221 and the internal lens group 222 are relatively fixed, and only the position of the image sensor 21 is adjusted to adjust the distance between the image sensor 21 and the incident light surface 220.

[0102] It should also be noted that, in some other embodiments, the lens group 222 can include a first lens group and a second lens group. The first lens group can be disposed within the lens barrel 221, and the second lens group can be disposed between the image sensor 21 and the first lens group. By compressing the gap inside the lens group 222 during the driving process of the first driving structure 500, it is possible to compress the height of the front camera 200 and achieve zooming in a state where the front camera 200 is completely accommodated within the chassis 100.

[0103] Please refer to Figure 17 and Figure 18 , in some embodiments, the mounting member 26 can be fixed to the chassis 100, and the lens barrel 221 can be connected to the mounting member 26 through a thread 261. Thus, the lens barrel 221 can be fixed to the chassis 100 together with the mounting member 26, and the fixing method of the lens barrel 221 and the mounting member 26 is simple and reliable.

[0104] Specifically, a threaded structure 261 is formed at the end of the lens barrel 221 close to the mounting member 26. A mating hole 260 is formed on the mounting member 26. The lens barrel 221 is mounted on the mounting member 26 through the threaded structure 261 and the mating hole 260. The mounting member 26 can be fixed to the middle frame 11 of the housing 100. For example, it can be rigidly mounted on the middle frame 11 of the housing 100 by fixing screws, so that the lens barrel 221 is fixed inside the housing 100 together. It can be understood that the mounting member 26, the lens barrel 221 and the middle frame 11 of the housing 100 form a structurally compact whole. Fixing the mounting member 26 on the housing 100 and the lens barrel 221 on the mounting member 26, the whole is fixed on the middle frame 11 of the housing 100 together, so that it can be used as the force base point when the image sensor 21 makes telescopic movement along the optical axis L1.

[0105] Please refer to Figures 14 - 15 , in some embodiments, the housing 100 includes a rear cover 12. The front camera 200 extends or retracts into the housing 100 through the rear cover 12. When the substrate 23 retracts into the housing 100, the outer surface of the substrate 23 is flush with the outer surface of the rear cover 12. In this way, by making the front camera 200 extend or retract into the housing 100 through the rear cover 12, it is possible to achieve a full-screen display of the electronic device 1000 and improve the imaging quality of the front camera 200 without increasing the thickness of the electronic device 1000; when the substrate 23 retracts into the housing 100, by making the outer surface of the substrate 23 flush with the outer surface of the rear housing, the appearance of the electronic device 1000 is flat and more beautiful.

[0106] Specifically, in the second embodiment, the embodiment of the present application can also adjust the distance between the light incident surface 220 and the image sensor 21 by moving the front camera 200 relative to the rear cover 12 along the optical axis L1. At this time, the height of the front camera 200 itself can be adjusted according to whether the front camera 200 is in the on state or the off state, so as to achieve the purpose of compressing the height of the front camera 200 in the off state, and it can also be used for zooming of the front camera 200.

[0107] For the front camera 200 in the second embodiment, since the front camera 200 is on the screen side and the screen cannot be opened for the front camera 200 to perform telescopic movement, the telescopic movement of the front camera 200 can be set relative to the rear cover 12 of the housing 100.

[0108] Among them, the first driving structure 500 drives the housing 25 of the front camera 200 to move along the optical axis L1, and further drives the substrate 23 connected to the housing 25 to move along the optical axis L1 relative to the rear cover 12 of the housing 100, and then drives the image sensor 21 to move along the optical axis L1 relative to the rear cover 12. At this time, the rear cover 12 is provided with a perforation 120 in the corresponding area of the substrate 23, and the size and shape of the perforation 120 correspond to the size and shape of the substrate 23, so that the substrate 23 can perform a telescopic action.

[0109] When the front camera 200 is in the working state, the substrate 23 extends out from the perforation 120 relative to the rear cover 12, and the outer surface of the substrate 23 is higher than the outer surface of the rear cover 12; when the front camera 200 is in the closed state, the substrate 23 retracts from the perforation 120 relative to the rear cover 12, and the outer surface of the substrate 23 is flush with the outer surface of the rear cover 12, making the appearance of the electronic device 1000 flat and more beautiful.

[0110] Please refer to Figures 19 - 20 , in some embodiments, the electronic device 1000 further includes a protective case 700 and a second driving structure 600. The protective case 700 has an avoidance space 71. The second driving structure 600 can drive the protective case 700 to at least partially extend out of the housing 100 or retract into the housing 100. When the protective case 700 at least partially extends out of the housing 100, the protective case 700 is tightly connected to the housing 100. When the first driving structure 500 drives the image sensor 21 to extend out of the housing 100, the image sensor 21 is located in the avoidance space 71.

[0111] In this way, when the image sensor 21 extends out of the housing 100, the image sensor 21 is located in the avoidance space 71, avoiding the image sensor 21 being directly exposed to the external environment.

[0112] Specifically, the housing 100 may include a rear cover 12, and a perforation 120 may be formed on the rear cover 12. In the third embodiment, the protective case 700 may be movably disposed on the housing 100, for example, movably disposed on the rear cover 12, and may move along the optical axis L1 relative to the rear cover 12 under the action of the second driving structure 600. The protective case 700 may be a hollow structure, and the hollow part may serve as the avoidance space 71 for accommodating the image sensor 21 when the image sensor 21 extends out of the housing 100.

[0113] The second driving structure 600 can be fixed on the rear cover 12 and is used to drive the protective shell 700 to extend at least partially out of the rear cover 12 or retract into the rear cover 12 through the perforation 120 on the rear cover 12. The first driving structure 500 can be fixed on the housing 100 and is connected to the outer shell 25 of the front camera 200 to drive the outer shell 25 to move along the optical axis L1, thereby driving the image sensor 21 on the substrate 23 to move along the optical axis L1. When the protective shell 700 extends at least partially out of the housing 100, the protective shell 700 is tightly connected to the housing 100. When the first driving structure 500 drives the image sensor 21 to extend out of the housing 100, the image sensor 21 is located in the avoidance space 71. Since the protective shell 700 is tightly connected to the housing 100, the image sensor 21 is prevented from being directly exposed to the external environment.

[0114] Please refer to Figures 19 - 20 , in some embodiments, during the process that the second driving structure 600 drives the protective shell 700 to extend at least partially out of the housing 100, the first driving structure 500 drives the image sensor 21 to extend out of the housing 100 and into the avoidance space 71. In this way, the image sensor 21 is prevented from being directly exposed to the external environment, which plays a protective role for the image sensor 21.

[0115] Specifically, in the third embodiment, the housing 100 includes a rear cover 12. A movable protective shell 700 is provided on the rear cover 12. The installation position of the protective shell 700 corresponds to the position of the front camera 200. The second driving structure 600 drives the protective shell 700 to perform telescopic movement relative to the rear cover 12, and the first driving structure 500 drives the outer shell 25 to expand and contract to adjust the distance between the image sensor 21 on the substrate 23 connected to the outer shell 25 and the light incident surface 220. Among them, the first driving structure 500 is driven by the second driving structure 600. When the second driving structure 600 drives the protective shell 700 to move, it will drive the first driving structure 500 to drive the outer shell 25 to expand and contract. In this way, the image sensor 21 is not directly exposed to the outside, which plays a protective role for the image sensor 21.

[0116] In some embodiments, the electronic device 1000 can include a driving component, and the driving component is used to drive at least one of the image sensor 21 and the optical component 22 to move relative to the other to adjust the distance between the image sensor 21 and the light incident surface 220. In this way, by adjusting the distance between the image sensor 21 and the light incident surface 220 through the driving component, while increasing the screen-to-body ratio of the electronic device 1000, the problem that the imaging quality of the front camera 200 is affected by the limited size of the front camera 200 due to the thickness limitation of the electronic device 1000 can be solved. Thus, an image sensor 21 with a relatively large size can be used as much as possible to improve the imaging quality of the front camera 200.

[0117] Specifically, the driving component is used to drive at least one of the image sensor 21 and the optical component 22 to move relative to the other. It can be that the driving component drives the image sensor 21 to move relative to the optical component 22, or it can be that the driving component drives the optical component 22 to move relative to the image sensor 21.

[0118] In the first embodiment, please refer to Figures 1 - 5 , Figure 9 and Figure 10 . The driving component may include a first driving mechanism 300 and a second driving mechanism 400. The driving component performs a first drive to drive the front camera 200 to extend out of the housing 100 or retract into the housing 100 through the first driving mechanism 300, and can also drive the optical component 22 to move along the optical axis L1 through the second driving mechanism 400 to adjust the distance between the light incident surface 220 and the image sensor 21.

[0119] Please refer to Figure 16 . In the second embodiment, the driving component may include a first driving structure 500, so that the driving component can perform a second drive to drive the housing 25 of the front camera 200 to move along the optical axis L1, and then drive the substrate 23 connected to the housing 25 to move relative to the rear cover 12 of the housing 100 along the optical axis L1, and then drive the image sensor 21 to move relative to the rear cover 12 along the optical axis L1; or, please refer to Figure 19 and Figure 20 . In the third embodiment, the driving component may include a first driving structure 500 and a second driving structure 600 to implement the second drive. Among them, the second driving structure 600 is used to drive at least part of the protective shell 700 to extend out of the housing 100, and the first driving structure 500 is used to drive the image sensor 21 to extend out of the housing 100 and into the avoidance space 71 during the process that at least part of the protective shell 700 extends out of the housing 100.
