Description

Retractable camera modules and electronics

technical field

The present application relates to the field of camera modules, and in particular, to miniaturized and retractable camera modules and electronic devices for terminal equipment.

Background technique

With the popularization of mobile electronic devices, the related technologies of camera modules used in mobile electronic devices to help users acquire images (eg, videos or images) have been rapidly developed and advanced. Currently in the market, a camera module configured in a mobile electronic device (eg, a smart phone) needs to achieve a multi-zoom shooting function.

In order to achieve multiple zoom shooting, at least one telephoto camera module needs to be configured (here, the telephoto camera module refers to a camera module with a larger effective focal length). Moreover, with the increase of the zoom factor, the total focal length of the telephoto camera module will increase accordingly, which leads to the continuous increase of the overall height and size of the camera module, which is difficult to adapt to the development trend of thin and light electronic devices.

In order to solve the technical contradiction between the height design of the camera module and the high-magnification zoom shooting function, most manufacturers use the periscope camera module to replace the traditional vertical camera module. Compared with the traditional upright camera module, the periscope camera module is provided with light turning elements (for example, prisms, mirrors, etc.) to change the imaging optical path, thereby reducing the overall height and size of the camera module at the same time. To meet the optical design requirements with a large effective focal length.

However, the periscope camera module has a relatively more complex structure, which on the one hand leads to an increase in the cost, and on the other hand, directly leads to an increase in the difficulty of the process. In terms of optical performance, although the periscope camera module has a relatively large effective focal length, its effective focal length is a fixed value, that is, the optical performance of the periscope camera module has relatively poor adjustability. In order to meet the diverse needs of consumers for camera modules, it is usually necessary to configure multiple camera modules for electronic devices, that is, to configure multiple camera modules for electronic devices, which not only brings about a surge in cost, but also further exacerbates process difficulty.

Therefore, a new type of camera module solution is required.

Correspondingly, in the embodiment of the present application, as shown in FIG. 1 and FIG. 2 , through the retractable sleeve assembly 33 , the optical lens 20 can be telescopically moved relative to the photosensitive chip 12 so that the Switch between a state and a second state, wherein when in the first state, the retractable sleeve assembly 33 is driven to move upward relative to the photosensitive chip 12 to drive the optical lens 20 relative to the photosensitive chip 12 moves upward to increase the distance between the optical lens 20 and the photosensitive chip 12 , as shown in FIG. 1 . As shown in FIG. 2 , when in the second state, the retractable sleeve assembly 33 is driven to be moved downward relative to the photosensitive chip 12 to drive the optical lens 20 to move toward the photosensitive chip 12 relative to the photosensitive chip 12 . move down to reduce the distance between the optical lens 20 and the photosensitive chip 12 . It should be understood that the first state is the working state of the retractable camera module 100 , and the second state is the non-working state of the retractable camera module 100 .

That is, in the embodiment of the present application, compared with the traditional upright camera module, the retractable camera module 100 has two states: a working state and a non-working state, wherein, when in the working state, The optical lens 20 is extended as the retractable sleeve assembly 33 is stretched upward, so that the distance between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements (here, the shooting requirements represent all The total optical length between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements); when in the non-working state, the optical lens 20 is retracted as the retractable sleeve assembly 33 is retracted downward. retracted, so that the overall height dimension of the retractable camera module 100 is reduced, so as to meet the size requirements for assembling the retractable camera module 100 in a terminal device. That is, in the working state and the non-working state, the distance between the optical lens 20 and the photosensitive chip 12 is adjusted by the retractable sleeve assembly 33, so that in the working state, the optical lens 20 The distance between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements, and in the non-working state, the distance between the optical lens 20 and the photosensitive chip 12 is shortened as much as possible, so that the retractable The overall height dimension of the camera module 100 can be reduced as much as possible.

More specifically, when the retractable camera module 100 is in a working state, the retractable sleeve assembly 33 is driven to be extended upward in a direction away from the photosensitive chip 12 . The overall height dimension of the retractable camera module 100 gradually increases. Correspondingly, when the retractable sleeve assembly 33 is fully extended, the overall height dimension of the retractable camera module 100 reaches the maximum value. Here, in order to For convenience of description, the maximum value is defined as the maximum height dimension, and the height dimension of the retractable camera module 100 represents the distance between the top surface and the bottom surface of the retractable camera module 100 .

Correspondingly, when the retractable camera module 100 is in a non-working state, the retractable sleeve assembly 33 is driven to be retracted downward in a direction close to the photosensitive chip 12 . The overall height dimension of the telescopic camera module 100 is gradually reduced. Correspondingly, when the telescopic sleeve assembly 33 is fully retracted, the overall height dimension of the telescopic camera module 100 reaches a minimum value, here , for the convenience of description, the minimum value is defined as the minimum height dimension, and the height dimension of the retractable camera module 100 represents the distance between the top surface and the bottom surface of the retractable camera module 100 .

Specifically, when the retractable camera module 100 is configured as the rear camera module of the terminal device, that is, when the retractable camera module 100 is installed on the back of the terminal device, the minimum The height dimension is basically the same as the thickness dimension of the terminal device. Here, the minimum height dimension is substantially consistent with the thickness dimension of the terminal device, indicating that after the retractable camera module 100 is installed in the terminal device, its upper end surface is flush with the back of the terminal device, or, slightly below the back of the terminal device. Of course, according to actual requirements, the upper end surface of the retractable camera module 100 can also be higher than the back surface of the terminal device, but generally speaking, for the sake of beauty, the protruding height cannot be too large, and can generally be controlled between 0mm and between 5mm.

Correspondingly, when the retractable camera module 100 is configured as a rear camera module of a terminal device, in the working state, the optical lens 20 of the retractable camera module 100 will be extended out, so that the distance between the optical lens 20 and the photosensitive chip 12 meets the requirements for the optical back focus value of zoom shooting, so that the imaging quality can be guaranteed. As shown in FIG. 1 , in a working state, the height of the retractable camera module 100 is significantly larger than the thickness of the terminal device. It should be understood that, in a specific implementation, the maximum height size and the minimum height size depend on the requirements of the terminal device for the optical zoom magnification.

Specifically, taking the use of the retractable idol module to achieve 5x optical zoom as an example, the range of the minimum height size is 8mm-11mm, preferably, the range of the minimum height size is 9mm-10mm; The range of the maximum height dimension is 23mm-26mm, preferably, the range of the maximum height dimension is 24mm-25mm. Taking the use of the retractable idol module to achieve 10x optical zoom as an example, the range of the minimum height size is 9mm-12mm, preferably, the range of the minimum height size is 10mm-11mm; the maximum height The size is in the range of 28mm-32mm, preferably, the maximum height dimension is in the range of 29mm-31mm.

In addition, when in the working state, the optical back focus value of the retractable camera module 100 is the largest, and when in the non-working state, the optical back focus value of the retractable camera module 100 is the smallest. More specifically, taking the retractable camera module 100 being used for 5x optical zoom as an example, in the working state, the optical back focus value of the retractable camera module 100 ranges from 13mm to 17mm. , preferably 14 to 16 mm; in a non-working state, the optical back focus value of the retractable camera module 100 ranges from 1 mm to 3 mm, preferably 1.5 mm to 2.5 mm.

In addition, when in the working state, the mechanical back focus of the retractable camera module 100 is the largest, and when the retractable camera module 100 is in the non-working state, the mechanical back focus of the retractable camera module 100 is the smallest. Here, the mechanical back focus of the retractable camera module 100 represents the distance from the cut plane of the lower surface of the last optical lens 22 in the optical lens 20 to the image plane. The value of the mechanism back focus is relatively close to the optical back focus value of the retractable camera module 100 , and is basically reduced by about 0.5 mm on the basis of the optical back focus value.

In addition, it should be understood that when the retractable camera module 100 is in a working state, the retractable sleeve assembly 33 is driven to be extended upward in a direction away from the photosensitive chip 12. At this time, the The overall height dimension of the telescopic sleeve assembly 33 gradually increases, and accordingly, when the telescopic sleeve assembly 33 is fully extended, the overall height dimension of the telescopic sleeve assembly 33 reaches a maximum value. Correspondingly, when the retractable camera module 100 is in a non-working state, the retractable sleeve assembly 33 is driven to be retracted downward in a direction close to the photosensitive chip 12 . The overall height dimension of the telescopic sleeve assembly 33 gradually decreases, and accordingly, when the telescopic sleeve assembly 33 is fully retracted, the overall height dimension of the telescopic sleeve assembly reaches a minimum value. Specifically, in the embodiment of the present application, the minimum height dimension of the telescopic sleeve assembly 33 ranges from 6 mm to 9 mm, and the maximum height dimension of the telescopic sleeve assembly 33 ranges from 18.6 mm to 28.6 mm.

In order to realize that the telescopic sleeve assembly 33 can be telescopically moved relative to the photosensitive chip 12 , a driving force needs to be provided for the telescopic sleeve assembly 33 . As shown in FIG. 3 , in the embodiment of the present application, the driving force of the telescopic sleeve assembly 33 is provided by the driving element 31 , that is, in the embodiment of the present application, the telescopic sleeve assembly 33 It is a passive component itself and needs an external driving force to drive its movement.

As shown in FIG. 3 , it should be noted that in the embodiment of the present application, the upper end 331 of the retractable sleeve assembly 33 on which the optical lens 20 is mounted corresponds to the photosensitive chip 12 , and needs to be An unobstructed imaging path is maintained between the optical lens 20 and the photosensitive chip 12 , that is, no other components can be provided between the optical lens 20 and the photosensitive chip 12 . Therefore, in the embodiment of the present application, preferably, the driving element 31 is arranged on the side of the photosensitive chip 12 , that is, the driving element 31 is arranged on a certain side of the photosensitive chip 12 . For example, the driving element 31 is mounted on the circuit board 11 at a position on one side of the photosensitive chip 12 . In order to ensure the stability of the driving element 31 , more preferably, the driving element 31 is mounted on the area where the reinforcing plate 15 protrudes from the circuit board 11 .

Moreover, considering that: on the one hand, the interior space of the retractable camera module 100 is limited, and on the other hand, the photosensitive chip 12, the filter element 14, etc. Sensitive and fragile element, therefore, it is more preferable to mount the drive element 31 on the outside of the telescopic sleeve assembly 33 . It should be understood that when the driving element 31 is installed on the outer side of the telescopic sleeve assembly 33, the deployment position of the driving assembly is also located at the side of the photosensitive chip 12 and is relatively farther away from the photosensitive chip chip 12.

It is worth mentioning that when the driving element 31 is installed on one side of the photosensitive chip 12 or the outer side of the retractable sleeve assembly 33, the driving element 31 is all located in the retractable camera mode. Therefore, the retractable camera module 100 according to the embodiment of the present application has a compact structure.

It should be understood that the function of the driving element 31 is to provide a driving force for driving the telescopic sleeve assembly 33 to extend and retract. In a specific implementation, the force provided by the driving element 31 can directly act on the retractable sleeve assembly 33 to drive the retractable sleeve assembly 33 to perform a telescopic motion relative to the photosensitive chip 12 , As shown in Figure 4.

Further, in consideration of the relative positional relationship between the telescopic sleeve assembly 33 and the driving element 31 , the telescopic assembly 30 further includes a space between the driving element 31 and the telescopic sleeve assembly 33 . The transmission mechanism 32 between the transmission mechanism 32 transmits the driving force generated by the driving element 31 and acts on the telescopic sleeve assembly 33 through the transmission mechanism 32 .

Correspondingly, the transmission mechanism 32 includes a power receiving end 321 and a power output end 322, wherein the power receiving end 321 is coupled to the driving element 31 to receive the driving force generated by the driving element 31, and the The power output terminal 322 is used for outputting the driving force received by the power receiving terminal 321 .

In some examples of the present application, the power output end 322 can act on the upper end 331 of the telescopic sleeve assembly 33 , that is, the driving force generated by the driving element 31 is transmitted and acted on by the transmission mechanism 32 At the upper end 331 of the telescopic sleeve assembly 33, by driving the upper end 331 to drive other parts of the telescopic sleeve assembly 33 to move, so as to drive the telescopic sleeve assembly 33 to move relative to each other For the purpose of the telescopic movement of the photosensitive chip 12 .

It is worth mentioning that, in the embodiment of the present application, the optical lens 20 is mounted on the upper end 331 of the retractable sleeve assembly 33 , therefore, when the power output end 322 of the transmission mechanism 32 acts When the upper end 331 of the retractable sleeve assembly 33 is located, the telescopic motion of the optical lens 20 and the retractable sleeve assembly 33 will be relatively smoother and smoother.

In particular, in these examples, since the driving element 31 is disposed on the side of the photosensitive chip 12 , the power output end 322 of the transmission mechanism 32 acts on the upper end 331 of the telescopic sleeve assembly 33 (The upper end portion 331 corresponds to the photosensitive chip 12 ), in such a positional relationship, preferably, the transmission mechanism 32 further includes a steering element for steering the driving force generated by the driving element 31 323 , the steering element 323 is disposed between the driving element 31 and the upper end 331 of the telescopic sleeve assembly 33 . It should be understood that, by configuring the steering element 323 , the driving force generated by the driving element 31 can be more smoothly transmitted to the upper end 331 of the telescopic sleeve assembly 33 . In a specific implementation, the steering element 323 includes, but is not limited to, pulleys, gears, crank connecting rods, and the like.

In other examples of the present application, the power output end 322 can also act on the lower end 332 of the telescopic sleeve assembly 33 , that is, the driving force generated by the driving element 31 is transmitted through the transmission mechanism 32 and act on the lower end 332 of the telescopic sleeve assembly 33 to drive the lower end 332 to drive other parts of the telescopic sleeve assembly 33 to move, so as to drive the telescopic sleeve assembly 33 For the purpose of telescopic movement relative to the photosensitive chip 12 .

Of course, in other examples of the application, the power output end 322 can also act on other positions of the telescopic sleeve assembly 33 , for example, the middle position, the middle upper position, the middle lower position of the telescopic sleeve assembly 33 Locations, etc., are not limited by this application. It is worth mentioning that in other examples of the present application, the power output end 322 can also directly act on the optical lens 20 , that is, the power output end 322 can directly act on the telescopic sleeve mounted on the The optical lens 20 of the upper end portion 331 of the barrel assembly 33 .

It is also worth mentioning that, in other examples of the present application, the driving element 31 can also drive the telescopic sleeve assembly 33 to perform telescopic movement relative to the photosensitive chip 12 in other ways. For example, in some examples of the present application, the telescopic assembly 30 further includes an elastic restoring member 34 disposed between the photosensitive chip 12 and the upper end 331 of the telescopic sleeve assembly 33 , the elastic restoring member 34 One end of the retractable sleeve assembly 33 is in contact with the upper end 331 of the retractable sleeve assembly 33 , wherein, in a natural state, the elastic restoring member 34 will bounce upward due to its own elasticity, so as to drive the retractable sleeve assembly 33 to do away from the protruding movement of the photosensitive chip 12 . Accordingly, in these examples, the driving element 31 may act on the upper end 331 of the retractable sleeve assembly 33 or the optical lens 20 through the transmission mechanism 32 (eg, lead wire) to provide pullback The driving force of the retractable sleeve assembly 33 or the optical lens 20 . Correspondingly, in the process of pulling back the elastic restoring member 34 by the driving mechanism, the elastic restoring member 34 is compressed and the driving mechanism is applied to the retractable sleeve assembly 33 or the optical lens 20 The driving force of the optical lens 20 is balanced with the elastic force of the elastic restoring member 34, so that the optical lens 20 can be pulled back and kept in a non-working state. That is, in these examples, the driving element 31 directly acts on the retractable sleeve assembly 33 (or the optical lens 20 ) to drive the retractable sleeve assembly 33 to act relative to the photosensitive chip 12 The retracting movement of the telescopic sleeve assembly 33 relative to the photosensitive chip 12 is driven by the elastic restoring member 34 instead of being directly driven by the driving element 31 .

Correspondingly, in these examples, the driving element 31 is disposed on the side of the photosensitive chip 12 , and the power output end 322 of the transmission mechanism 32 acts on the upper end 331 ( The upper end portion 331 corresponds to the photosensitive chip 12). Under such a positional relationship, preferably, the transmission mechanism 32 further includes a steering element 323 for steering the driving force generated by the driving element 31, and the steering element 323 is disposed on the driving element 31 and the upper end 331 of the telescopic sleeve. It should be understood that, by configuring the steering element 323 , the driving force generated by the driving element 31 can be more smoothly transmitted to the upper end 331 of the telescopic sleeve assembly 33 . In a specific implementation, the steering element 323 includes, but is not limited to, pulleys, gears, crank connecting rods, and the like.

Further, in these examples, in order to enable the retractable camera module 100 to be kept in a non-working state, the retractable assembly 30 may further include a limiting element, wherein when the optical lens 20 is closed by the When the driving element 31 is pulled back, the limiting element can prevent the retractable sleeve assembly 33 from being rebounded by the elastic restoring member 34 by restricting the transmission mechanism 32 (eg, a rope). In a specific implementation, the limiting element can be implemented as the driving element 31 itself, that is, when the driving element 31 is in a non-working state, the driving element 31 can still provide a protection against the retractable sleeve assembly 33 being returned The force of the bullet. Of course, the limiting element may also be an element disposed outside the driving element 31 , which is not limited by this application.

It is worth mentioning that when the retractable camera module 100 is in the working state, the optical lens 20 is moved away from the photosensitive chip 12 under the action of the retractable sleeve assembly 33, so that all The distance between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements. Correspondingly, since the distance between the optical lens 20 and the photosensitive chip 12 is increased, the imaging optical path between the optical lens 20 and the photosensitive chip 12 is extended, resulting in more external stray light. It may enter the photosensitive chip 12 to affect the image quality.

In order to solve the problem that stray light affects imaging, in some examples of the present application, the retractable camera module 100 further includes an upper end portion that is retractably extended to the photosensitive chip 12 and the retractable sleeve assembly 33 A guide sleeve 40 between 331 , the guide sleeve 40 has a through hole corresponding to the optical lens 20 and the photosensitive chip 12 . It should be understood that the guide sleeve 40 disposed between the optical lens 20 and the photosensitive chip 12 can be designed by its own shape and size, on the one hand to constrain the imaging light from the optical lens 20, and on the other hand In one aspect, stray light from outside the conduction sleeve is isolated from entering the photosensitive chip 12 .

In a specific example of the present application, as shown in FIG. 3 , one end of the guide sleeve 40 is fixed to the upper end 331 of the telescopic sleeve assembly 33 , and the other end of the guide sleeve 40 is fixed above the photosensitive chip 12 . (For example, it is fixed on the bracket 13 ), wherein, when in the first state, the retractable sleeve assembly 33 is driven to move upward relative to the photosensitive chip 12 to drive the guide sleeve 40 to move relative to the photosensitive chip 12 . The photosensitive chip 12 is elongated upward; when in the second state, the retractable sleeve assembly 33 is driven to be moved downward relative to the photosensitive chip 12 to drive the guide sleeve 40 to be relatively The photosensitive chip 12 is shortened downward. That is, in this specific example, the conducting sleeve is capable of telescopic movement along with the telescopic sleeve assembly 33 .

In order to ensure that enough imaging light enters the photosensitive chip 12 , in the embodiment of the present application, preferably, the inner diameter of the guide sleeve 40 gradually increases from top to bottom, and the lower part of the guide sleeve 40 is The end face covers the photosensitive area of the photosensitive chip 12 in the projection area of the photosensitive chip 12 . That is, the lower end surface of the guide sleeve 40 can completely cover the photosensitive area of the photosensitive chip 12, so that the imaging light entering the photosensitive chip 12 through the guide sleeve 40 can completely cover the photosensitive area The imaging area of the chip 12 .

Further, as shown in FIG. 1 to FIG. 3 , in the embodiment of the present application, the telescopic sleeve assembly 33 has a multi-section structure, that is, the telescopic sleeve assembly 33 includes a plurality of sections nested in each other. Sleeve unit 333 . The multi-section sleeve units 333 can interact with each other so as to be able to extend relative to the photosensitive chip 12 or to retract relative to the photosensitive chip 12 after being driven. Here, the multi-section sleeve units 333 can interact with each other, which means that there is force transmission or direct contact between the multi-section sleeve units 333 . Preferably, in the embodiment of the present application, two adjacent sleeve units 333 of the multi-segment sleeve units 333 are in contact with each other, for example, they are arranged in a layer-by-layer nesting manner, so as to form all the The retractable sleeve assembly 33 is described.

For example, in some specific examples of the present application, the multi-segment sleeve units 333 of the telescopic sleeve assembly 33 are sleeved with each other, and between two adjacent sleeve units 333 A guide groove 330A (eg, as shown in FIG. 6 ) is provided, and the guide groove 330A allows telescopic movement between the inner and outer two sleeve units 333 in the direction of the optical axis. In some other examples of the present application, the multi-segment sleeve units 333 of the telescopic sleeve assembly 33 are sleeved with each other, and between two adjacent segments of the sleeve units 333 are provided A guide rail 330B (for example, as shown in FIG. 3 ), the guide rail 330B allows a helical telescopic movement between the inner and outer two sleeve units 333 in the direction of the optical axis, that is, the sleeve unit located in the inner layer The 333 can perform a spiral upward movement or a spiral downward movement under the action of the sleeve unit 333 located in the outer layer.

In the embodiment of the present application, the lower end 332 of the outermost sleeve unit 333 of the multi-segment sleeve unit 333 forms the lower end 332 of the telescopic sleeve assembly 33, and the multi-segment sleeve unit 333 The upper end 331 of the innermost sleeve unit 333 of the body 333 forms the upper end 331 of the retractable sleeve assembly 33, that is, in the embodiment of the present application, the optical lens 20 is installed in the innermost On the sleeve unit 333 of the outermost layer, the sleeve unit 333 of the outermost layer is mounted on the mounting substrate of the photosensitive element 10 .

Correspondingly, when the telescopic sleeve assembly 33 is driven in the working state, the sleeve units 333 in the outermost layer are fixed, and the sleeve units 333 in the inner layer are moved upward one by one. It is extended to move away from the photosensitive chip 12 , so that the total optical length between the optical lens 20 and the photosensitive chip 12 can be increased to meet the shooting requirements.

In a specific implementation, the structural configuration between the multi-section sleeve units 333 is determined based on the driving mode of the telescopic assembly 30 . Specifically, as mentioned above, in some examples, in the working state, the power output end 322 of the transmission mechanism 32 in the telescopic assembly 30 directly acts on the upper end 331 of the telescopic sleeve assembly 33 , under the action of the power output end 322, the sleeve unit 333 located in the innermost layer is lifted up to drive the outer sleeve unit 333 to move upward layer by layer. In this way, the optical lens 20 is kept away from the photosensitive chip 12 . In this driving mode, the multi-segment sleeve units 333 may adopt a structural configuration in which the inner and outer sleeves are nested and the two adjacent sleeve units 333 can slide up and down.

Specifically, as mentioned above, in other examples, in the working state, the power output end 322 of the transmission mechanism 32 in the telescopic assembly 30 directly acts on the lower end of the telescopic sleeve assembly 33 332, under the action of the power output end 322, the sleeve unit 333 located in the outermost layer is rotated to drive the outer sleeve unit 333 to rotate and move upward layer by layer. In this way , to drive the optical lens 20 away from the photosensitive chip 12 . In this driving mode, the multi-segment sleeve units 333 can adopt a structural configuration in which the inner and outer sleeves are nested and the two adjacent sleeve units 333 can be helically slidable.

It is worth mentioning that, as mentioned above, in the embodiment of the present application, the minimum height dimension of the retractable camera module 100 should meet the preset requirements. Therefore, in the embodiment of the present application, the multi-section The height of each sleeve unit 333 connected to the sleeve unit 333 is not higher than the required height of the retractable camera module 100 . For example, when the height of the retractable camera module 100 is 9.5 mm, the height of each section of the sleeve unit 333 is less than or equal to 9.5 mm. Preferably, in the embodiment of the present application, each of the sleeve monomers 333 in the multi-section sleeve monomers 333 has a consistent height dimension.

In addition, it should be easily understood that, in the embodiment of the present application, the highest height dimension of the retractable camera module 100 is determined by the height dimension of each sleeve unit 333 in the multi-segment sleeve units 333 and the The total number of segments of the multi-segment sleeve unit 333 is determined. That is, to a certain extent, the maximum height dimension of the retractable camera module 100 can be controlled by controlling the number of sections of the multi-section sleeve unit 333 . That is, in the embodiment of the present application, the number of sections of the multi-section sleeve unit 333 is determined based on the quotient of the maximum height dimension of the telescopic sleeve assembly 33 and the height of the sleeve unit 333 .

For example, in a specific example, the height dimension of the sleeve unit 333 is equal to the minimum height dimension of the telescopic sleeve assembly 33 , and each sleeve unit in the multi-section sleeve unit 333 333 have consistent height dimensions, and the maximum height dimension of the telescopic sleeve assembly 33 is equal to the sum of the height dimensions of the multi-section sleeve units 333 .

In order to better understand the design of the height and the number of sections of the single-segment sleeve unit 333 of the telescopic sleeve assembly 33, a specific example is provided.

In this specific example, the height requirement of the terminal device for the retractable camera module 100 is 9.5 mm, the effective focal length of the optical lens 20 of the retractable camera module 100 is 21 mm, and the retractable camera module 100 has an effective focal length of 21 mm. The total optical length of the camera module 100 is also 21 mm, and the height of the optical lens 20 is 7.3-7.5 mm. In this specific example, in the working state, the height of the optical lens 20 to the photosensitive chip 12 is 24 mm, the height of the optical lens 20 is 7.3 mm, and the retractable camera module 100 needs The height dimension is 9.5mm, therefore, the telescopic assembly 30 must be provided for the optical lens 20, so that the optical lens 20 is in a corresponding height position in the working state, so that the TTL meets the requirements. The module 100 can shoot normally.

In this specific example, the outermost sleeve unit 333 of the telescopic sleeve assembly 33 is fixed on the circuit board 11 or other fixing parts (for example, the reinforcing plate 15 as described above), the The overall extension length of the telescopic sleeve assembly 33 is approximately 24 mm. In order to allow the retractable sleeve assembly 33 to be completely retracted into the retractable camera module 100, the height of each sleeve unit 333 is less than 9.5 mm (it is worth mentioning that due to the existence of all the The height of the circuit board 11 and other components, the height of each sleeve unit 333 may need to be further controlled), therefore, the number of sections of the telescopic sleeve assembly 33 should be at least three.

Further, in the embodiment of the present application, since the motion control precision of the telescopic assembly 30 is limited, and in the specific shooting process, the relative positional relationship between the telescopic camera module 100 and the subject is not The same, therefore, when using the retractable camera module 100 for shooting, preferably, the retractable camera module 100 needs to be focused to improve the shooting quality. That is, in the embodiment of the present application, the retractable camera module 100 further includes a focusing mechanism 50 .

In a specific example of the present application, the focusing mechanism 50 is disposed between the retractable sleeve assembly 33 and the optical lens 20, and is configured to drive the optical lens 20 to fine-tune the optical lens The relative positional relationship between 20 and the photosensitive chip 12 is used for optical focusing. Specifically, the focusing mechanism 50 includes, but is not limited to, a voice coil motor, piezoelectric ceramics, and the like.

In another specific example of the present application, the focusing mechanism 50 may be configured to act on a certain position of the telescopic sleeve assembly 33 , for example, act on the innermost sleeve of the telescopic sleeve assembly 33 The barrel unit 333 is used to perform optical focusing by driving the retractable sleeve assembly 33 and the optical lens 20 as a whole.

In yet another specific example of the present application, the focusing mechanism 50 may be configured to act on the photosensitive chip 12 , that is, the focusing mechanism 50 may fine-tune the photosensitive chip 12 by driving the photosensitive chip 12 to move. The distance between the optical lens 20 and the optical lens 20 for optical focusing.

To sum up, the retractable camera module 100 is illustrated based on the embodiment of the present application, wherein the optical lens 20 in the retractable camera module 100 is retractable relative to the photosensitive chip 12 thereof, so as to be able to operate and not work In the working state, the optical lens 20 of the retractable camera module 100 is extended for imaging, and in the non-working state, the optical lens of the retractable camera module 100 20 is retracted to reduce the overall height dimension of the retractable camera module 100. In this way, the technical contradiction between the height design and the larger effective focal length of the conventional vertical camera module is resolved.

FIG. 6 illustrates a schematic perspective view of a specific example of the telescopic assembly 30 of the telescopic camera module 100 according to an embodiment of the present application. FIG. 7 is a schematic exploded perspective view of the telescopic assembly 30 shown in FIG. 6 . As shown in FIG. 6 and FIG. 7 , in this specific example, the telescopic assembly 30 includes: a driving element 31 , a transmission mechanism 32 and an elastic recovery member 34 , wherein the driving element 31 , the transmission mechanism 32 and the The elastic restoring member 34 cooperates to drive the telescopic sleeve assembly 33 to switch between a working state and a non-working state.
