In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

Referring to fig. 1 to 5, an embodiment of the present invention provides an electronic device 1000, where the electronic device 1000 includes a housing 100 and a front camera 200, the front camera 200 may at least partially protrude out of the housing 100 or be completely accommodated in the housing 100, the front camera 200 includes an image sensor 21 and an optical assembly 22, the image sensor 21 is disposed on an optical axis L1 of the optical assembly 22, the optical assembly 22 includes a light incident surface 220 facing away from the image sensor 21, a distance between the light incident surface 220 and the image sensor 21 is a first distance D1 in a case where the front camera 200 at least partially protrudes out of the housing 100, a distance between the light incident surface 220 and the image sensor 21 is a second distance D2 in a case where the front camera 200 is completely accommodated in the housing 100, and the second distance D2 is smaller than the first distance D1 (as shown in fig. 6 and 7).

In this way, by enabling the front camera 200 to partially extend out of the casing 100 and be completely accommodated in the casing 100, and adjusting the distance between the light incident surface 220 and the image sensor 21, the screen occupation ratio of the electronic device 1000 can be improved, and meanwhile, the problem that the imaging quality is affected by the limitation of the thickness of the electronic device 1000 on the size of the front camera 200 is solved, so that the image sensor 21 with a larger size can be used as much as possible, and the imaging quality of the front camera 200 is improved.

Specifically, there are two technical solutions for the front camera 200 of the existing electronic device at present, the first is to place the front camera 200 inside the electronic device, and the front camera is also inside the electronic device in an operating state, and an opening is formed on a screen for front imaging.

The second is that telescopic mechanical structure (or the telescopic mechanical structure of side) about adopting, when leading camera 200 during operation, stretches out leading camera 200 from electronic equipment's inside and then shoots, when leading camera 200 was out of work, with the inside of leading camera 200 shrink to electronic equipment, electronic equipment's full screen display can be realized to this kind of scheme.

However, in any of the above solutions, the front camera 200 is limited by the thickness of the electronic device, and the height dimension of the front camera is compressed, so that the front camera 200 can only use the image sensor 21 with a smaller size to reduce the height dimension of the front camera, thereby affecting the imaging quality of the front camera 200.

In view of this, the present application provides an electronic device 1000, which aims to adjust the overall height of the front camera 200 on the premise of ensuring that the overall screen display and the thickness of the electronic device 1000 are constant, so as to adopt an image sensor 21 with a larger size as much as possible on the premise of ensuring the reasonable height size of the front camera 200, thereby improving the imaging quality.

For convenience of explanation, a mobile phone may be described as a specific example of the electronic device 1000 according to the embodiment of the present application. It is understood that the electronic apparatus 1000 may be other devices with a front camera 200 besides a mobile phone, such as a tablet computer, an e-book reader, an MP3 player, an MP4 player, a car computer, a desktop computer, a smart tv, or a wearable device.

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 the image sensor 21 and the optical assembly 22, so that the distance from the light incident surface 220 of the optical assembly 22 away from the image sensor 21 to the image sensor 21 is adjustable, thereby compressing the height of the front camera 200 when the front camera 200 is disposed inside the electronic device 1000. Further, as shown in fig. 4 and 5, only when there is a shooting requirement, the front camera 200 may be at least partially extended out of the housing 100, so as to increase the distance between the light incident surface 220 and the image sensor 21, thereby meeting the shooting requirement, and thus enabling the front camera 200 to provide better shooting effects of photos and videos for users.

Specifically, the housing 100 may be made of metal or plastic. The housing 100 may be configured to receive the image sensor 21, the optical assembly 22, and the like, and it is understood that, as shown in fig. 2 to 5, the housing 100 may be formed with an avoiding hole 13, and when the front camera 200 moves in a direction perpendicular to the optical axis L1, the front camera may extend out of the housing 100 or retract into the housing 100 through the avoiding hole 13.

As shown in fig. 6-9, the image sensor 21 is disposed on an optical axis L1 of the optical assembly 22, the optical assembly 22 may include a lens set for imaging, and the optical assembly 22 includes an incident surface 220 facing away from the image sensor 21. As shown in fig. 4-6, when the front camera 200 is in the working state, at least a portion of the front camera 200 extends out of the housing 100, and a distance between the light incident surface 220 and the image sensor 21 is a first distance D1; as shown in fig. 2-3 and 7, when the front camera 200 is not used, the front camera 200 may be completely accommodated in the housing 100, and a distance between the light incident surface 220 and the image sensor 21 is a second distance D2, and the second distance D2 is smaller than the first distance D1.

It can be understood that, in order to meet the requirement of image capturing and improve the image capturing quality, the size of the image sensor 21 may be increased or a lens with higher resolving power and larger aperture may be adopted, however, the optical total length of the lens collocated with the image sensor 21 with a larger area is also larger, so the height size of the front camera 200 is also increased, and the thickness size of the electronic device 1000 is increased accordingly. In the first embodiment of the present application, the front camera 200 of the electronic device 1000 is movable relative to the casing 100 to at least partially extend out of the casing 100 or be completely accommodated in the casing 100, so that after the front camera 200 extends out of the casing 100, the distance from the light incident surface 220 to the image sensor 21 is increased, and therefore, the large-sized image sensor 21 can be used to ensure the shooting quality of the front camera 200 while ensuring a certain thickness of the electronic device 1000.

Referring to fig. 2-5 and fig. 10, in some embodiments, the electronic device 1000 may include a first driving mechanism 300, wherein the first driving mechanism 300 is configured 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, the predetermined direction in which the first driving mechanism 300 drives the front camera 200 to move is perpendicular to the optical axis L1, and the anti-shake function can be realized.

Specifically, the first driving mechanism 300 may be a screw motor driving type, a belt driving type, a rack and pinion driving type, and the like, and the embodiment of the present application does not inherently limit the specific driving type of the first driving mechanism 300. As long as the first driving mechanism 300 can drive the front camera 200 to move in the direction perpendicular to the optical axis L1 so that the front camera 200 can be extended out of the housing 100 or retracted into the housing 100 in the direction perpendicular to the optical axis L1.

Thus, when a user needs to use the front camera 200 to shoot, the first driving mechanism 300 can eject the whole module of the front camera 200 out of the casing 100, and then adjust the specific positions of the optical assembly 22 and the image sensor 21 after ejecting out of the casing 100 to obtain a better shooting effect. At this time, it can be understood that the first driving mechanism 300 is mainly used for driving 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 (i.e. inside and outside the housing 100), that is, the predetermined direction may be any angle direction in the plane of the electronic device 1000, for example, the predetermined direction extends along the length direction of the electronic device 1000, or the predetermined direction extends along the width direction, as long as the predetermined direction is perpendicular to the optical axis L1 to realize the anti-shake function.

Referring to fig. 10, in some embodiments, the first driving mechanism 300 may include a bracket 31 and a driving assembly 32. The bracket 31 may be connected to a driving assembly 32, the front camera 200 may be mounted on the bracket 31, and the driving assembly 32 may move relative to the casing 100 by driving the bracket 31, so as to extend or retract the front camera 200 out of or into the casing 100.

In this way, the bracket 31 is arranged to mount the front camera 200 on the bracket 31, so that the front camera 200 and the bracket 31 form a compact whole, and thus the front camera 200 can be driven to move relative to the casing 100 by driving the bracket 31 to move.

Specifically, the bracket 31 may be a plastic or alloy metal member, and the positioning groove 310 may be formed on the bracket 31 for rigidly fixing the front camera 200 and other structures. The holder 31 may include a top plate 311 and a bottom plate 312, and in a state where the front camera 200 is completely accommodated in the housing 100, the top plate 311 of the holder 31 is flush with the surface of the housing 100, or the top plate 311 of the holder 31 seals the avoiding hole 13 of the housing 100.

The driving assembly 32 may be connected with the bracket 31, and specifically, the driving assembly 32 may include a driving motor 320 and a transmission assembly 321. The driving motor 320 may be a stepping motor, the transmission assembly 321 may include a screw 3210 and a nut 3211, and the driving assembly 32 may further include a reducer 3212, such as a harmonic reducer 3212. The driving motor 320 may be fixedly mounted with the casing 100, the nut 3211 may be mounted on the lower surface of the bottom plate 312, a mounting hole 3120 may be formed on the bottom plate 312, and the screw 3210 may penetrate through the mounting hole 3120 on the bottom plate 312 and penetrate through the nut 3211, so that the casing 100, the driving assembly 32, the bracket 31, and the front camera 200 form a compact whole.

Thus, the driving motor 320 can drive the screw 3210 to rotate through the reducer 3212, the nut 3211 is rigidly fixed on the bottom plate 312 to rotate along with the screw 3210, so that the nut 3211 drives the bracket 31 to move in a predetermined direction relative to the casing 100, thereby driving the front camera 200 to extend out of the casing 100 or retract into the casing 100. It can be understood that the bracket 31 is provided to mount the front camera 200, so that the movement of the front camera 200 is more stable, and the bracket 31 can provide a supporting function for the front camera 200.

Referring to fig. 10, in some embodiments, the first driving mechanism 300 may further include a guide assembly 33, the guide assembly 33 may connect the casing 100 and the bracket 31, and the guide assembly 33 may be used to guide the bracket 31 to move. In this way, the guiding component 33 connects the casing 100 and the bracket 31, so that the guiding component 33, the casing 100 and the bracket 31 form a compact whole; the guiding component 33 can provide guiding function for the movement of the bracket 31 relative to the casing 100, and at the same time, make the movement of the bracket 31 relative to the casing 100 more stable.

Referring to fig. 10, in some embodiments, the guiding assembly 33 may include a mounting base 330 and a guide rod 331, the mounting base 330 may be connected to the casing 100, one end of the guide rod 331 may be connected to the mounting base 330, the guide rod 331 may be inserted into the bracket 31, and the bracket 31 may move relative to the guide rod 331. In this way, the guiding component 33 is connected with the casing 100 through the mounting seat 330 and connected with the bracket 31 through the guide rod 331, so that the guiding component 33 is arranged on the casing 100, and the guide rod 331 provides a stable guiding function for the bracket 31, and the structure is simple and the guiding function is reliable.

Specifically, it can be understood that if the guide assembly 33 is not provided, the bracket 31 is driven to move relative to the casing 100 only by the driving assembly 32, so that the movement of the bracket 31 is unstable. The guide assembly 33 in the present application may include a mounting seat 330 and a guide rod 331, the mounting seat 330 may have various regular or irregular shapes such as a circle, an ellipse, a polygon, etc., the mounting seat 330 may serve as a base for fixing the guide rod 331 to be fixed in the cabinet 100, and the guide rod 331 may be inserted through the mounting hole 3120 of the bracket 31 on the bottom plate 312 of the bracket 31 and fixed on the mounting seat 330 through the fixing hole 3300 of the mounting seat 330. The bracket 31 is movable relative to the guide rod 331 under the action of the driving assembly 32, and the guide rod 331 can provide a guiding function for the movement of the bracket 31 relative to the casing 100, and simultaneously, the movement of the bracket 31 relative to the casing 100 is more stable.

Referring to fig. 9, in some embodiments, the electronic device 1000 may include a second driving mechanism 400, and the second driving mechanism 400 may be configured to drive at least a portion of the optical assembly 22 to move along the optical axis L1 to adjust the distance between the light incident surface 220 and the image sensor 21. Thus, the imaging quality of the front camera 200 can be improved, and the thickness of the electronic device 1000 is not affected.

Specifically, the second driving mechanism 400 may be configured to drive at least a portion of the optical assembly 22 to move along the optical axis L1, such that, in the first embodiment of the present application, the front camera 200 may be driven by the first driving mechanism 300 to extend and retract on the plane of the electronic device 1000, thereby implementing state transition of the front camera 200 inside and outside (i.e., inside and outside the housing 100) of the electronic device 1000, and the second driving mechanism 400 may be configured to drive the front camera 200 to extend and retract along the optical axis L1, i.e., to extend and retract along the plane perpendicular to the electronic device 1000, thereby implementing distance adjustment between the optical assembly 22 and the image sensor 21.

The second drive mechanism 400 may be driven by means of a spring and a mating member, may be controlled by means of a stepper motor and a gear box, or may be implemented by a large stroke autofocus motor. The embodiments of the present application do not inherently limit the specific implementation of the second driving mechanism 400.

It can be easily understood that, in the embodiment of the present application, the front camera 200 is ejected out of the casing 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, so that when the 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 in the casing 100 is not increased, and the overall thickness of the electronic device 1000 is increased. Thus, the height of the front camera 200 can be reduced when the front camera 200 is arranged inside the electronic device 1000, the thickness of the electronic device 1000 is prevented from being affected, and the imaging quality of the front camera 200 can be improved.

In some embodiments, the second driving mechanism 400 may be configured to drive at least a portion of the optical assembly 22 to move along the optical axis L1 in a direction away from the image sensor 21 during the process of the first driving mechanism 300 driving the front camera 200 to extend out of the housing 100. As such, in the first embodiment, the second driving mechanism 400 and the first driving mechanism 300 may work simultaneously, so that during the process of the first driving mechanism 300 driving the front camera 200 to extend out of the housing 100, the second driving mechanism 400 can drive at least part of the optical assembly 22 to move along the optical axis L1 in a direction away from the image sensor 21. Like this, can adjust leading camera 200 to suitable formation of image position more fast when having leading camera 200 user demand, improve and shoot efficiency and improve user experience.

Referring to fig. 9, 11 and 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 assembly 22 and the substrate 23. In this way, the image sensor 21 can be fixed on the bracket 31 through the substrate 23, and the second driving mechanism 400 connects the optical assembly 22 and the substrate 23, so that the second driving mechanism 400 can drive at least part of the optical assembly 22 to move along the optical axis L1 in a direction away from the substrate 23 or close to the substrate 23.

Specifically, the substrate 23 may be fixed on the positioning groove 310 of the bracket 31, and the image sensor 21 is disposed on the substrate 23, and may be, for example, adhered to the substrate 23 or mounted on the substrate 23 by other fixing means. The second driving mechanism 400 may connect the optical assembly 22 and the substrate 23, such that the second driving mechanism 400 may drive at least a portion of the optical assembly 22 to move along the optical axis L1 in a direction away from the substrate 23 or close to the substrate 23.

Referring to fig. 9, 11 and 12, in some embodiments, the optical assembly 22 includes a lens barrel 221 and a first lens group 223 disposed in the lens barrel 221, the first lens group 223 includes a light incident surface 220, and the second driving mechanism 400 is connected to the lens barrel 221 and the substrate 23.

Specifically, the first lens group 223 may be configured to collect an external optical signal, and the lens barrel 221 may protect the first lens group 223. The substrate 23 may be fixed on the positioning groove 310 of the holder 31, the image sensor 21 is disposed on the substrate 23, and since the second driving mechanism 400 connects the lens barrel 221 and the substrate 23, the second driving mechanism 400 may drive the lens barrel 221 to move along the optical axis L1 in a direction away from the substrate 23 or in a direction close to the substrate 23. The lens barrel 221 can protect the first lens group 223 disposed in the lens barrel 221, and the first lens group 223 is driven to move along the optical axis L1 in a direction away from the substrate 23 or close to the substrate 23 to move to a proper position, so as to obtain a better imaging effect.

Referring to fig. 9, 11 and 12, in some embodiments, the optical assembly 22 may further include a second lens group 224, the second lens group 224 is disposed coaxially 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 is fixed relative to the image sensor 21. Specifically, the first lens group 223 and the second lens group 224 are used for imaging, and in the first embodiment, when the second driving mechanism 400 is operated, the first lens group 223 moves along the direction of the optical axis L1 relative to the second lens group 224 and the image sensor 21, and the second lens group 224 remains stationary. Of course, in other embodiments, only the image sensor 21 may be disposed on the substrate 23 and kept stationary, and the second driving mechanism 400 drives the first lens group 223 and the second lens group 224 to move together.

Referring to fig. 9, 11 and 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 to the lens barrel 221 to move in a direction away from the image sensor 21. In this way, the distance between the lens barrel 221 and the image sensor 21, that is, the distance between the first lens group 223 and the image sensor 21, after the front camera 200 is ejected out of the housing 100, can be adjusted by the elastic member 41; meanwhile, the elastic element 41 can also compress the height of the front camera 200 through the cooperation of the elastic element 41 and other components when the front camera 200 is retracted into the casing 100, so as to avoid affecting the lightness and thinness of the electronic device 1000.

Specifically, the elastic member 41 may be a spiral spring, and the center line 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 a receiving groove formed in 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; in the process that the first driving mechanism 300 drives the front camera 200 to extend out of the housing 100, in the case that the second driving mechanism 400 drives at least part of the optical assembly 22 to move along the optical axis L1 in the direction away from the image sensor 21, the elastic member 41 gradually changes from the compressed state to the relaxed state to provide the lens barrel 221 with a force moving in the direction away from the image sensor 21.

In addition, the second driving mechanism 400 further includes a guide 42, the guide 42 may be a plurality of guide posts, in the first embodiment, three guide 42 are distributed in a regular triangle, and a center enclosed by the three guide 42 coincides with the optical axis L1, the guide 42 may 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 the image sensor 21 or close to the image sensor 21, the guide 42 may guide the movement of the lens barrel 221.

Referring to fig. 9, 11 and 12, in some embodiments, the lens barrel 221 may have a first fitting component 2211, and the housing 100 may have a second fitting component 14, and when the first driving mechanism 300 drives the front camera 200 to extend out of the housing 100, the lens barrel 221 gradually moves away from the image sensor 21 under the action of the force and the first fitting component 2211 and the second fitting component 14.

Specifically, in the first embodiment, the lens barrel 221 may include a first portion 225 and a second portion 226 connected, wherein the diameter of the second portion 226 is larger than that of the first portion 225, and the first portion 225 is disposed on the surface of the second portion 226 to form a step structure. The first portion 225 and the second portion 226 may be annular, and the first lens group 223 may be disposed on the first portion 225.

First fitting 2211 may be annular, first fitting 2211 may be concentric with barrel 221, and first fitting 2211 may be disposed on second portion 226 and surround first portion 225. First fitting piece 2211 may be rigidly fixed on the upper surface of second portion 226, or first fitting piece 2211 may be directly formed during the processing of lens barrel 221, so that first fitting piece 2211 and lens barrel 221 are integrally formed.

The second mating member 14 may be cam shaped and the second mating member 14 may have a ramped or inclined surface. The second mating member 14 may be fixedly connected to the casing 100, for example, welded or adhered to the inside of the casing 100. In the first embodiment, when the front camera 200 is completely accommodated in the chassis 100, the second fitting member 14 and the first fitting member 2211 may abut together, so that the second fitting member 14 may fit the gap between the compression lens barrel 221 and the image sensor 21, and the size of the front camera 200 is reduced; when the front camera 200 extends out of the chassis 100 in a predetermined direction perpendicular to the optical axis L1, the first mating member 2211 moves in the predetermined direction to move away from the second mating member 14, so that the lens barrel 221 gradually moves away from the image sensor 21 under the action of the acting force and the first mating member 2211 and the second mating member 14 until the front camera 200 is completely ejected out of the chassis 100, the lens barrel 221 also moves to the working position along the optical axis L1, and the end of the second mating member 14 can abut against the first mating member 2211.

In addition, referring to fig. 8, 11 and 12, in some embodiments, the lens barrel 221 may have a light inlet 2212, and the first fitting piece 2211 protrudes from the light inlet 2212 along the direction of the optical axis L1. It can be understood that the light inlet 2212 of the lens barrel 221 can collect external light and facilitate the light sensing of the image sensor 21, at this time, the first fitting piece 2211 is disposed on the second portion 226 and disposed around the first portion 225, and since the first lens group 223 can be disposed on the first portion 225, in order to protect the first portion 225 of the lens barrel 221 when adjusting the first lens group 223, i.e. the distance between the lens barrel 221 and the image sensor 21, and avoid the second fitting piece 14 from interfering with the first portion 225 of the lens barrel 221, the first fitting piece 2211 can protrude out of the light inlet 2212 along the direction of the optical axis L1.

Referring to fig. 11 and 12, in some embodiments, the second mating member 14 may include a mating surface 140 facing the image sensor 21, and the distance H between the mating surface 140 and the image sensor 21 increases gradually along the direction that the front camera 200 extends out of the housing 100, and the first mating member 2211 may abut against the mating surface 140.

As such, when the first driving mechanism 300 drives the front camera 200 to retract into the chassis 100, the first fitting piece 2211 may cooperate with the second fitting piece 14 to move the lens barrel 221 of the front camera 200 along the optical axis L1 toward the image sensor 21, so as to compress the thickness dimension of the front camera 200, thereby enabling the front camera 200 to fully retract into the chassis 100.

Specifically, the mating surface 140 of the second mating member 14 facing the image sensor 21 may be an inclined surface or an inclined curved surface, and the distance between the mating surface 140 and the image sensor 21 gradually increases along the direction in which the front camera 200 extends out of the housing 100. In the first embodiment, as shown in fig. 7 and 11, 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, the elastic element 41 is in the compressed state, and the second mating element 14 mates with the first mating element 2211 to compress the gap between the lens barrel 221 and the image sensor 21, so as to reduce the size of the front camera 200.

As shown in fig. 6 and 12, after the front camera 200 is opened, the first driving mechanism 300 operates, and the driving bracket 31 drives the front camera 200 to extend out of the housing 100 in a predetermined direction perpendicular to the optical axis L1, during the ejection process, since the distance H between the mating surface 140 of the second mating member 14 and the image sensor 21 is gradually increased, that is, the thickness of the second mating member 14 in the direction of the optical axis L1 is gradually decreased, a space is made for the lens barrel 221 to move along the optical axis L1 in the direction away from the image sensor 21, and further the lens barrel 221 moves along the optical axis L1 in the direction away from the image sensor 21 under the action of the force and the first mating member 2211 and the second mating member 14 until the front camera 200 is completely ejected out of the housing 100, and the lens barrel 221 also moves to a proper position, so that the front camera 200 starts to operate.

When the front camera 200 is closed, the first driving mechanism 300 operates to drive the front camera 200 to be integrally retracted into the casing 100 along the predetermined direction perpendicular to the optical axis L1, and while the front camera is retracted, the thickness of the second fitting piece 14 in the direction along the optical axis L1 is gradually increased, that is, the distance H between the fitting surface 140 and the image sensor 21 is gradually reduced, so that the front camera can be retracted into the casing 100 along the optical axis L1, the lens barrel 221 provided with the first fitting piece 2211 is compressed downwards by the second fitting piece 14, the height of the front camera 200 is reduced, and the front camera 200 can be retracted into the casing 100.

Referring to fig. 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 mounted in the housing 24, and the housing 24 may be connected to the substrate 23. The housing 24 may protect the image sensor 21, the first lens group 223, and the second lens group 224. In addition, the housing 24 may include a stopper surface away from the image sensor 21, and when the lens barrel 221 is ejected in a direction in which the optical axis L1 is too far away from the image sensor 21, the stopper surface may restrict the lens barrel 221 from continuing to eject.

In particular, in one embodiment, the front camera 200 may be provided with a large stroke autofocus motor to effect movement of the lens barrel 221 relative to the image sensor 21. Meanwhile, the front camera 200 may have auto-focusing and optical anti-shake functions, so that the optical assembly 22 may have a better and more stable imaging effect after adjusting the distance between the optical assembly 22 and the light incident surface 220. As shown in fig. 13 below, the large working stroke of the autofocus motor of the front camera 200 can be divided into two strokes, and the purpose of the two strokes is different.

The first stroke is a telescopic stroke along the optical axis L1, and is to reduce the height of the whole 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; the second stroke belongs to the auto-focusing stroke of the front camera 200.

After the front camera 200 is turned on, the first driving mechanism 300 drives the front camera 200 to pop out to the outside of the electronic device 1000 along a predetermined direction, and after the pop-up is completed, the large-stroke auto-focusing motor of the front camera 200 works to drive the lens barrel 221 to move to the vertex C of the first stroke, and then the automatic focusing is performed by applying the second stroke according to the imaging definition of the front camera 200.

After the front camera 200 is closed, the large-stroke auto-focusing motor of the front camera 200 works first to drive the lens barrel 221 to move to the bottom point of the stroke two (i.e., the top point of the stroke one), and then continues to move along the optical axis L1 toward the direction close to the image sensor 21 until the lens barrel moves to the zero point D of the full stroke of the auto-focusing motor; the first driving mechanism 300 then drives the front camera 200 to retract into the electronic device 1000 along a predetermined direction.

In some embodiments, the electronic device 1000 includes a display screen covering the front camera 200, the front camera 200 captures images through the display screen, and the image sensor 21 is movable 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.

Therefore, the overall screen display effect of the electronic device 1000 can be achieved, and meanwhile, the image sensor 21 can move along the optical axis L1 relative to the display screen 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 light weight and the thinness of the electronic device 1000.

Specifically, in the first mentioned embodiment, the front camera 200 may be ejected at the top or the side of the chassis 100, and then the lens barrel 221 may be moved along the optical axis L1 with respect to the image sensor 21 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 condition of the front camera 200 to which the large-sized image sensor 21 is applied.

As shown in fig. 14 to 16, in the second embodiment, the distance between the light incident surface 220 and the image sensor 21 can be adjusted by moving the image sensor 21 along the optical axis L1 with respect to the display screen. At this time, the height of the front camera 200 itself can be adjusted according to whether the front camera 200 is in the open state or the closed state, so that the purpose of compressing the height of the front camera 200 in the closed state is achieved, and the front camera 200 can be zoomed. In the front camera 200 according to the second embodiment, since the front camera 200 is located at the screen side, the screen cannot be perforated to allow the front camera 200 to perform the telescopic motion, and thus the telescopic motion of the front camera 200 can be set to be a motion relative to the display screen.

Referring to fig. 14-17, in some embodiments, the light incident surface 220 may be fixed relative to the display screen, and the electronic device 1000 may include a first driving structure 500, and the first driving structure 500 may be configured to drive the image sensor 21 to extend out of the housing 100 or retract into the housing 100. Therefore, on the premise of meeting the requirement of the lightness and thinness of the electronic device 1000, the comprehensive screen display of the electronic device 1000 can be realized, and the imaging quality of the front camera 200 can be improved.

Specifically, the first driving structure 500 may be a screw motor driving type, a belt driving type, a rack and pinion driving type, and the like, and the embodiment of the present application does not inherently limit the specific driving type 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 casing 100 or retract into the casing 100, it should be noted that the casing 100 in the second embodiment may include the battery rear cover 12 of the electronic device 1000.

Thus, when a user needs to use the front camera 200 to shoot, the first driving structure 500 drives the image sensor 21 to extend out of the housing 100 to adjust the distance from the image sensor 21 to the light incident surface 220, so that the distance from the light incident surface 220 to the image sensor 21 is increased, and thus, the large-sized image sensor 21 can be used under the condition that a certain thickness of the electronic device 1000 is ensured, and the shooting quality of the front camera 200 is ensured.

Referring to fig. 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, and the first driving structure 500 is configured to drive the housing 25 to move, so as to extend the substrate 23 out of the casing 100 or retract the substrate 23 into the casing 100. In this way, the housing 25 can protect the image sensor 21 disposed on the substrate 23, so that the image sensor 21 is covered by the housing 25 when the first driving structure 500 drives the housing 25 to move to drive the substrate 23 to extend out of the casing 100.

Specifically, the substrate 23 is configured to mount the image sensor 21 on the substrate 23, so that the image sensor 21 and the substrate 23 form a compact whole, the housing 25 is configured to be connected to the substrate 23, so that the housing 25, the substrate 23 and the image sensor 21 form a compact whole, the housing 25 can protect the image sensor 21, and the housing 25 can be driven to move to drive the image sensor 21 on the substrate 23 to move relative to the chassis 100.

Specifically, the substrate 23 may be bonded or welded to the housing 25, the substrate 23 may be rectangular, the outer contour of the housing 25 may be square or rectangular, the housing 25 and the substrate 23 may be plastic or alloy, and the image sensor 21 may be bonded to the substrate 23 or mounted on the substrate 23 by other fixing methods. The first driving structure 500 may be installed inside the casing 100 and connected to the housing 25, and in the second embodiment, the casing 100 may include a rear cover 12, and the rear cover 12 is formed with a through hole 120, so that the housing 25 may drive the substrate 23 to extend out of the rear cover 12 through the through hole 120 under the driving of the first driving structure 500.

At this time, it can be understood that the outer surface of the substrate 23 may serve as a partial appearance of the electronic device 1000 in a state where the front camera 200 is completely accommodated in the casing 100, and then the substrate 23 may be made of the same material as the casing 100, so that the overall appearance of the electronic device 1000 is consistent and more beautiful, and particularly, the outer surface of the substrate 23 may be flush with the outer surface of the rear cover 12 in a state where the front camera 200 is completely accommodated in the casing 100. The top plate 311 of the substrate 23 is flush with the surface of the casing 100, so that the electronic device 1000 is relatively flat and beautiful.

Referring to fig. 17 and 18, in some embodiments, the optical assembly 22 includes a lens barrel 221 and a lens group 222 disposed in the lens barrel 221, the lens group 222 includes a light incident surface 220, the lens barrel 221 is at least partially disposed in the housing 25, the housing 25 is movable relative to the lens barrel 221, and the lens barrel 221 can be fixed to the chassis 100 by the mounting member 26. Thus, the lens barrel 221 can protect the lens group 222 disposed therein to a certain extent.

Specifically, a through hole 250 may be formed in the housing 25, and the through hole 250 may be used to provide an avoiding 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 in the lens barrel 221 can be used for collecting external light for subsequent imaging. The lens barrel 221 may be fixed to the casing 100 by a mounting member 26, and in the case that the casing 100 includes the middle frame 11, the lens barrel 221 may be mounted on the middle frame 11 of the casing 100 by the mounting member 26, so that when the first driving structure 500 operates, the lens barrel 221 and the inner lens group 222 are relatively fixed, and the distance between the image sensor 21 and the light incident surface 220 is adjusted only by adjusting the position of the image sensor 21.

It should be noted that, in other embodiments, the lens group 222 may include a first lens group and a second lens group, the first lens group may be disposed in the lens barrel 221, and the second lens group may be disposed between the image sensor 21 and the first lens group, and by compressing a gap inside the lens group 222 during the driving process of the first driving structure 500, the front camera 200 may be highly compressed in a state where the front camera 200 is completely accommodated in the casing 100, and zooming may be achieved.

Referring to fig. 17 and 18, in some embodiments, the mounting member 26 may be fixed to the casing 100, and the lens barrel 221 may be connected to the mounting member 26 by a screw 261. Thus, the lens barrel 221 can be fixed to the chassis 100 by the mounting member 26, and the manner of fitting and fixing the lens barrel 221 to the mounting member 26 is simple and reliable.

Specifically, the end of the lens barrel 221 near the mounting part 26 is formed with a screw 261 structure, the mounting part 26 is formed with a fitting hole 260, the lens barrel 221 is mounted on the mounting part 26 through the screw 261 structure fitting hole 260, and the mounting part 26 can be fixed on the middle frame 11 of the casing 100, for example, can be rigidly mounted on the middle frame 11 of the casing 100 through a fixing screw, so that the lens barrel 221 is fixed inside the casing 100 together. It can be understood that the mounting member 26 and the lens barrel 221 are integrally formed with the middle frame 11 of the housing 100 in a compact structure, and the mounting member 26 is fixed to the housing 100, and the lens barrel 221 is fixed to the mounting member 26 and is integrally fixed to the middle frame 11 of the housing 100, thereby being able to serve as a base point of a force when the image sensor 21 performs a telescopic movement along the optical axis L1.

Referring to fig. 14-15, in some embodiments, the housing 100 includes a rear cover 12, and the front camera 200 extends or retracts into the housing 100 through the rear cover 12, and in a state where the substrate 23 is retracted into the housing 100, an outer surface of the substrate 23 is flush with an outer surface of the rear cover 12. In this way, by extending or retracting the front camera 200 out of or into the casing 100 through the rear cover 12, the overall screen display of the electronic device 1000 and the imaging quality of the front camera 200 can be improved without increasing the thickness of the electronic device 1000; by making the outer surface of the substrate 23 flush with the outer surface of the rear case in the state where the substrate 23 is retracted into the casing 100, the appearance of the electronic device 1000 is flat and more beautiful.

Specifically, in the second embodiment, the distance between the light incident surface 220 and the image sensor 21 can be adjusted 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 open state or the closed state, so that the purpose of compressing the height of the front camera 200 in the closed state is achieved, and the front camera 200 can be zoomed.

In the front camera 200 according to the second embodiment, since the front camera 200 is located on the screen side, the screen cannot be perforated to allow the front camera 200 to perform the telescopic motion, and therefore, the front camera 200 can be arranged to be telescopic with respect to the rear cover 12 of the housing 100.

The first driving structure 500 drives the housing 25 of the front camera 200 to move along the optical axis L1, and then drives the substrate 23 connected to the housing 25 to move along the optical axis L1 relative to the rear cover 12 of the chassis 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 through hole 120 in a region corresponding to the substrate 23, and the size and shape of the through hole 120 correspond to the size and shape of the substrate 23 so that the substrate 23 can be extended and contracted.

When the front camera 200 is in a working state, the substrate 23 extends out of the through hole 120 relative to the rear cover 12, and the outer surface of the substrate 23 is higher than that of the rear cover 12; when the front camera 200 is in the closed state, the substrate 23 is retracted from the through hole 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, so that the electronic device 1000 has a flat and more beautiful appearance.

Referring to fig. 19 to 20, in some embodiments, the electronic device 1000 further includes a protective shell 700 and a second driving structure 600, the protective shell 700 has an avoidance space 71, the second driving structure 600 can drive the protective shell 700 to at least partially extend out of the housing 100 or retract into the housing 100, the protective shell 700 is tightly connected to the housing 100 when the protective shell 700 at least partially extends out of the housing 100, and the image sensor 21 is located in the avoidance space 71 when the first driving structure 500 drives the image sensor 21 to extend out of the housing 100.

Thus, by positioning the image sensor 21 in the escape space 71 with the image sensor 21 protruding outside the housing 100, the image sensor 21 is prevented from being directly exposed to the external environment.

Specifically, the cabinet 100 may include a rear cover 12, and the rear cover 12 may have a perforation 120 formed thereon. In the third embodiment, the protective casing 700 may be movably disposed on the casing 100, for example, movably disposed on the rear cover 12, and may be moved along the optical axis L1 with respect to the rear cover 12 by the second driving structure 600. The protective case 700 may have a hollow structure, and the hollow portion may serve as an escape space 71 for accommodating the image sensor 21 when the image sensor 21 protrudes out of the housing 100.

A second driving mechanism 600 may be secured to the rear cover 12 for driving the protective shell 700 at least partially out of the rear cover 12 or back into the rear cover 12 through the through-hole 120 in the rear cover 12. The first driving structure 500 may be fixed on the casing 100 and connected to the housing 25 of the front camera 200 to drive the housing 25 to move along the optical axis L1 so as to drive the image sensor 21 on the substrate 23 to move along the optical axis L1. Under the condition that the protective shell 700 at least partially extends out of the machine shell 100, the protective shell 700 is tightly connected with the machine shell 100, and under the condition that the first driving structure 500 drives the image sensor 21 to extend out of the machine shell 100, the image sensor 21 is positioned in the avoidance space 71, and due to the tight connection between the protective shell 700 and the machine shell 100, the image sensor 21 is prevented from being directly exposed to the external environment.

Referring to fig. 19 to 20, in some embodiments, during the process that the second driving mechanism 600 drives the protective shell 700 to at least partially extend out of the casing 100, the first driving mechanism 300 drives the image sensor 21 to extend out of the casing 100 and into the avoiding space 71. Thus, the image sensor 21 is prevented from being directly exposed to the external environment, and the image sensor 21 is protected.

Specifically, in the third embodiment, the housing 100 includes the rear cover 12, the movable protective housing 700 is disposed on the rear cover 12, the disposition position of the protective housing 700 corresponds to the position of the front camera 200, the second driving structure 600 drives the protective housing 700 to perform telescopic motion relative to the rear cover 12, and the first driving structure 500 drives the housing 25 to extend and retract, so as to adjust the distance between the image sensor 21 on the substrate 23 connected to the housing 25 and the light incident surface 220, wherein the first driving structure 500 is driven by the second driving structure 600, and when the second driving structure 600 drives the protective housing 700 to move, the first driving structure 500 is driven to drive the housing 25 to extend and retract. Thus, the image sensor 21 is not directly exposed to the outside, and the image sensor 21 is protected.

In some embodiments, the electronic device 1000 may include a driving component for driving at least one of the image sensor 21 and the optical assembly 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, the distance between the image sensor 21 and the light incident surface 220 is adjusted by the driving component, so that the screen occupation ratio of the electronic device 1000 is improved, and meanwhile, the problem that the imaging quality is affected by the limitation of the thickness of the electronic device 1000 on the size of the front camera 200 is solved, so that the image sensor 21 with a larger size can be used as far as possible, and the imaging quality of the front camera 200 is improved.

Specifically, the driving component is used for driving at least one of the image sensor 21 and the optical assembly 22 to move relative to the other, and may be used for driving the image sensor 21 to move relative to the optical assembly 22, or driving each component to drive the optical assembly 22 to move relative to the image sensor 21.
