The present embodiment is described by taking an example in which the retractable camera assembly 100 is extended in the positive Z-axis direction. The rear cover 320 is provided with mounting holes 420, and the retractable camera assembly 100 is disposed to correspond to the mounting holes 420. The object-side end of the retractable camera assembly 100 is disposed in the mounting hole 420, and collects light through the mounting hole 420.

In other words, the lens module is a lens of the rear camera. In other embodiments, the location of the mounting holes 420 includes, but is not limited to, being either side of the bezel 311, or a corner of the bezel 311, etc.

It is to be understood that the electronic device 1000 described above is an application form of the retractable camera head assembly 100 provided in the present application, and the components included in the electronic device 1000 described above and the structure of each component and the like should not be construed as limiting the retractable camera head assembly 100 provided in the present application.

Referring to fig. 4 and 5, the retractable camera assembly 100 includes a housing case 1, a lens module 2, a photosensitive module 3, a supporting frame 4 and a driving module 5.

Referring to fig. 2, 4 and 5, the receiving case 1 is mounted in the mounting hole 420 and fixed with respect to the rear cover 320. The housing case 1 has a housing cavity 1 a. The accommodating cavity 1a is used for accommodating the lens module 2, the photosensitive module 3 and the support frame 4.

Referring to fig. 6, the accommodating case 1 includes a top plate 111 and a bottom plate 112 disposed opposite to each other, and a peripheral side plate 113 connected between the top plate 111 and the bottom plate 112. The top plate 111 and the peripheral side plate 113 may be integrally formed, and the bottom plate 112 may be fixedly connected to the peripheral side plate 113 by means of fastening, screwing, or the like. The top plate 111 includes an outer wall 111a and an inner wall 111b opposite to each other, and an opening 111c penetrating the outer wall 111a and the inner wall 111 b. The opening 111c communicates with the housing chamber 1 a. The surface of the bottom plate 112 facing the top plate 111 is a bottom wall, and the bottom wall is also a surface of the bottom plate 112 facing the opening 111 c.

Referring to fig. 4 and 5, at least a portion of the lens module 2 is located in the accommodating case 1. Specifically, the lens module 2 includes a lens housing 21 and a lens group (not shown) disposed in the lens housing 21. The optical axis direction of the lens group is the positive direction of the Z axis. The size of the outer peripheral surface of the lens module 2 is matched with the size of the opening 111c, so that the lens module 2 can extend out or retract through the opening 111c, and the integrity of the appearance is kept.

Further, referring to fig. 5 and 6 in combination, the bottom of the lens housing 21 is provided with an extending edge 211. When the lens module 2 is in the extended state, the extended edge 211 of the lens housing 21 abuts against the top plate 111 to limit the maximum extension process of the lens module 2.

Referring to fig. 5, the photosensitive module 3 is fixed in the accommodating case 1 and disposed opposite to the lens module 2. Specifically, the photosensitive module 3 includes, but is not limited to, an image sensor 31 (see fig. 11), a flexible circuit board 32 electrically connected to the image sensor 31, and the like. The image sensor 31 is disposed on the flexible circuit board 32, and the image sensor 31 and the lens set are disposed opposite to each other along the Z-axis direction. The photosensitive module 3 may further include a steel patch of the flexible circuit board 32. Wherein the steel is supplemented to the side of the flexible circuit board 32 facing away from the image sensor 31. Optionally, the photosensitive module 3 may further include a filter 33. The filter 33 is disposed between the image sensor 31 and the lens set. The filter 33 includes, but is not limited to, an infrared filter 33 to filter the infrared light emitted through the lens assembly, so that the visible light emitted into the image sensor 31 has less interference.

Referring to fig. 5 and fig. 6, the position of the photosensitive module 3 fixed to the accommodating case 1 will not be described in detail. In this embodiment, the bottom plate 112 is provided with a step hole 112a communicating with the accommodating cavity 1a, an outer peripheral edge of the photosensitive module 3 is matched with an inner peripheral edge of the step hole 112a to seal the step hole 112a, and the image sensor 31 of the photosensitive module 3 is located in the accommodating cavity 1a and opposite to the lens group. In the present embodiment, the photo-sensing module 3 can be assembled to the housing case 1 through the stepped hole 112a from the outside of the housing case 1, and thus, a portion of the photo-sensing module 3 is exposed outside the housing case 1 to be electrically connected to the electrical connection structure on the middle frame 310 of the electronic device 1000. Of course, in other embodiments, the photosensitive module 3 may also be fixed on the side of the bottom plate 112 facing the top plate 111.

In the embodiment of the present application, the photosensitive module 3 and the lens module 2 form a camera module. The camera module comprises but is not limited to a main camera, a wide-angle camera, a long-focus camera, a macro camera and the like.

The supporting frame 4 is located between the lens module 2 and the photosensitive module 3. The supporting frame 4 supports the lens module 2. The supporting frame 4 is fixedly connected to one side of the lens module 2 facing the bottom plate 112. The supporting frame 4 is a hollow structure.

Specifically, referring to fig. 5, the supporting frame 4 has a supporting frame hole 4a, and the supporting frame hole 4a corresponds to the lens group of the lens module 2 and the image sensor 31 of the photosensitive module 3, so that the light of the lens group is emitted to the image sensor 31 through the supporting frame hole 4 a. Alternatively, the supporting frame 4 may be disposed substantially along the X-Y plane, the supporting frame 4 is supported at the bottom of the lens module 2, and when the supporting frame 4 moves along the Z-axis direction, the lens module 2 also moves along the Z-axis direction.

Referring to fig. 7, the driving module 5 is disposed on one side of the supporting frame 4. In the present embodiment, the driving module 5 and the support frame 4 are arranged in the X-axis direction.

Referring to fig. 7 and 8, the driving module 5 includes a driving unit 51 and a slider 52 connected to the driving unit 51. The driving unit 51 includes, but is not limited to, a structure for providing a driving force for a micro motor or the like. In the present embodiment, the driving unit 51 is a micro motor. The driving unit 51 is connected to the slider 52 in a specific connection manner including, but not limited to, a direct connection or an indirect connection. The indirect connection means that the driving unit 51 is connected with the sliding block 52 through a screw rod-nut combination, a worm wheel-worm combination, a gear-screw rod combination, a transmission belt/rope/chain-transmission wheel combination and the like.

In this embodiment, referring to fig. 7 and 8, the sliding block 52 has a supporting slope 521. The support slope 521 supports one end of the support frame 4. The driving unit 51 is used for driving the slider 52 to move back and forth along the first direction, so that the supporting frame 4 drives the lens module 2 to extend out of the accommodating case 1 or retract into the accommodating case 1 along the second direction. Wherein the first direction intersects the second direction. In the present embodiment, the first direction is the Y-axis direction, and the second direction is the Z-axis direction.

Specifically, the driving unit 51 is configured to drive the supporting slope 521 of the slider 52 to move back and forth along a first direction, the slider 52 generates component forces in the first direction and a second direction on the supporting frame 4 during the movement, and the supporting frame 4 moves along the second direction along with the movement of the slider 52 because the supporting frame 4 is relatively fixed in the first direction and the supporting frame 4 is movable in the second direction in the accommodating frame. For example, when the driving unit 51 drives the inclined supporting surface 521 of the slider 52 to move in the positive Y-axis direction, the slider 52 generates component forces in the positive Y-axis direction and the positive Z-axis direction on the supporting frame 4, and since the supporting frame 4 is constrained in the positive Y-axis direction and cannot move, and the supporting frame 4 can move in the positive Z-axis direction, the supporting frame 4 moves in the positive Z-axis direction under the action of the slider 52, and the lens module 2 is pushed to extend out of the accommodating case 1.

The driving unit 51 can also drive the supporting inclined plane 521 of the sliding block 52 to move along the reverse direction of the Y axis, the acting force of the supporting inclined plane 521 on the supporting frame 4 towards the positive direction of the Z axis is reduced, and the supporting frame 4 can be retracted into the accommodating shell 1 under the action of an external force or under the driving of the sliding block 52.

By arranging the slide block 52 in the driving module 5, the slide block 52 is pushed to move along a first direction, wherein the first direction is the transverse occupying direction of the retractable camera assembly 100, so that the space reserved for the slide block 52 in the first direction is small, in addition, a supporting inclined plane 521 is arranged on the slide block 52 to convert into a pushing force towards a second direction so as to push the lens module 2 to extend out of the accommodating shell 1, in the process of retracting the lens module 2, the slide block 52 is gradually retracted to an initial position by driving to retract an acting force on the lens module 2, and the lens module 2 is retracted to the accommodating shell 1 under the action of an external force or the slide block 52; the movement of the slider with the supporting slope 521 gradually raises the supporting frame 4 or provides a retraction space for the supporting frame 4, so that the extension stability of the lens module 2 in extension or retraction can be improved.

The embodiment of the present application in which the lens module 2 is retracted into the housing case 1 is not particularly limited, and includes, but is not limited to, the following embodiments.

Optionally, referring to fig. 9a, at least one elastic element 61 is disposed in the accommodating case 1. The elastic member 61 is elastically connected between the supporting frame 4 and the top plate of the accommodating case 1. Further, the elastic member 61 is sleeved on the guide rod 62, and the guide rod 62 extends along the Z-axis direction. When the lens module 2 is in the extended state, the elastic member 61 is in a compressed state. When the slider 52 moves toward the direction approaching the driving unit 51, the pushing force of the slider 52 against the lens module 2 is gradually reduced or even disappears, and the lens module 2 retracts to the accommodating case 1 along the supporting slope 521 under the pushing force of the elastic member 61.

By arranging the elastic element 61, the supporting frame 4 gradually extends out of the accommodating shell 1 along the supporting inclined plane 521 under the action of the slide block 52 in the direction of the Z axis, and simultaneously the elastic element 61 is gradually extruded so as to extend out of the lens module 1, so that the focal distance of the camera module can be adjusted to be clear for imaging; after the camera module is used, the slider 52 moves in the opposite direction along the Y axis under the action of the driving unit 51, the acting force of the slider on the support frame 4 is reduced, and the support frame is gradually retracted into the accommodating case 1 under the action of the elastic member 61, so that the camera module is accommodated.

Alternatively, referring to fig. 9b, the elastic element 61 is elastically connected between the supporting frame 4 and the bottom plate 112 of the accommodating case 1. Further, the elastic member 61 is sleeved on the guide rod 62, and the guide rod 62 extends along the Z-axis direction.

When the lens module 2 is in the extended state, the elastic member 61 is in a stretched state. When the slider 52 moves toward the direction approaching the driving unit 51, the pushing force of the slider 52 on the lens module 2 is gradually reduced or even disappears, and the lens module 2 retracts to the accommodating case 1 along the supporting inclined plane 521 under the action of the elastic member 61.

The lens module 2 can be extended or retracted into the housing case 1 in the optical axis direction (Z-axis direction) by the driving module 5. Since the photosensitive module 3 is fixed to the accommodating case 1, the lens module 2 can move along the optical axis direction relative to the photosensitive module 3, or the image distance (or back focal length) of the lens module 2 changes along with the expansion and contraction of the lens module 2. Therefore, the camera module in which the lens module 2 is located is also called a retractable camera module or an extendable camera module. It can be understood that the number of the retractable camera modules in the electronic device 1000 is one or more.

The lens module 2 has at least two states including an extended state and a retracted state with respect to the photosensitive module 3 (or with respect to the housing case 1). The following description will be given taking as an example a state in which the lens module 2 is extended to the maximum extension process, but the extended state in the present application may be a state in which the lens module is extended but does not reach the maximum extension process. The lens module 2 moves from the retracted state to the extended state, and optical zooming of the camera module is achieved.

Referring to fig. 10 to 12, the lens module 2 is in a retracted state, and the camera module is in a non-operating state, i.e., a storage state. Referring to fig. 13 to 15, the lens module 2 is in a half-extended state, and the camera module is in a working state or a non-working state. Referring to fig. 16 to 18, the lens module 2 is in an extended state, and the lens module 2 is in an imaging position of the camera module, at this time, the camera module is in a working state.

In the electronic device with a fixed camera proposed in the general technology, because the module thickness of the camera is limited by the lightness and thinness of the electronic device (the thickness of the electronic device), after the module thickness of the camera is limited, the light-sensing area of the camera is also limited accordingly, so that the light-sensing area of the camera is relatively small, and the imaging definition, the fidelity and the like of the camera are influenced to a certain extent. Moreover, the existing camera is very sensitive to height, and an excessively high module can cause the rear cover of the electronic equipment to form a sharp bulge, which affects the appearance of the whole appearance of the electronic equipment such as a mobile phone.

This application can follow one side that back lid 320 deviates from display screen 200 through the lens module 2 of the scalable camera subassembly 100 of design, when scalable camera subassembly 100 is in the state of stretching out, for the module thickness of the normal work of scalable camera subassembly 100, that is to say, the module thickness of scalable camera subassembly 100 no longer receives the restriction of electronic equipment 1000's thickness, has realized that the module thickness of scalable camera subassembly 100 is great relatively and electronic equipment 1000's thickness is less compatibility relatively. Because the retractable camera assembly 100 has a relatively large thickness in the extended state, the size of the photosensitive module 3 of the retractable camera assembly 100 can be set to be relatively large (i.e., the large-sized image sensor 31), so that the lighting area of the retractable camera assembly 100 is relatively large, and a better quality image can be obtained. In the present embodiment, the surface on which the photosensitive module 3 is located is substantially parallel to the X-Y plane, and the electronic apparatus 1000 itself has a large space on the X-Y plane, so the electronic apparatus 1000 also has the potential to accommodate a large photosensitive module 3. When the retractable camera assembly 100 is in the retracted state, the lens module 2 retracts to be accommodated in the accommodating space 410, and at this time, the retractable camera assembly 100 does not form a protruding protrusion on the rear cover 320, which is beneficial to the good appearance of the electronic device 1000 and the touch feeling of the hand touch of the user.

In addition, compared with the scheme that the rear cover 320 extends from the side of the housing 300, in the scheme that the camera module extends from the side, because the extending direction of the camera module intersects with the facing direction of the camera module, the camera module extends integrally, that is, the lens module 2 and the photosensitive module 3 extend together, and the requirements of zooming the lens module 2 relative to the photosensitive module 3 and setting the outsole image sensor 31 when the camera module extends cannot be met; still because relations such as cell-phone thickness, lens module 2 and drive module 5 can only be along the direction mode of arranging that stretches out, consequently, whole camera subassembly is great relatively in the ascending size in the direction of stretching out, and the scalable camera subassembly 100 that this embodiment provided not only can realize lens module 2 and zoom when stretching out and can set up the demand of big end image sensor 31, can also effectually avoid the too big problem of scalable camera subassembly 100 in the electronic equipment 1000 in the direction of stretching out.

In other words, the sliding slope 441 has the same inclination angle as the supporting slope 521. By providing the sliding inclined surface 441 on the protruding portion 44, the support stability of the slider 52 for the support frame 4 is increased by the abutting sliding between the sliding inclined surface 441 and the support inclined surface 521.

The initial position of the connection portion 522 is a position close to the first fixing plate 541 or a position abutting against the first fixing plate 541. At this time, the projection 44 is located at the second position S2 of the supporting slope 521. The end position of the connecting portion 522 is a position close to the second fixing plate 542 or a position abutting against the second fixing plate 542, and at this time, the protruding portion 44 is located at the first position S1 of the supporting inclined surface 521 (where the second position S2 is a position where the supporting inclined surface 521 is close to the top plate 111).
