In the working state, the optical lens of the telescopic camera module is extended for imaging. In the non-working state, the optical lens of the telescopic camera module is retracted to reduce the overall height dimension of the telescopic camera module.

Description

Technical Field

[0001] This application relates to the field of camera modules, and more particularly to miniaturized scalable camera modules and electronic devices for terminal devices. Background Technology

[0002] With the widespread adoption of mobile electronic devices, the technology related to camera modules used in these devices to help users acquire images (e.g., videos or pictures) has developed and progressed rapidly. Currently, camera modules configured in mobile electronic devices (e.g., smartphones) need to achieve multi-zoom shooting capabilities.

[0003] To achieve multi-zoom shooting, at least one telephoto camera module is required (here, a telephoto camera module refers to a camera module with a large effective focal length). Furthermore, as the zoom level increases, the total focal length of the telephoto camera module also increases, leading to a continuous increase in the overall height of the camera module, making it difficult to adapt to the trend of thinner and lighter electronic devices.

[0004] To resolve the technical conflict between the height design of camera modules and high-magnification zoom capabilities, most manufacturers have adopted periscope camera modules to replace traditional vertical camera modules. Compared to traditional vertical camera modules, periscope camera modules incorporate light-deflecting elements (such as prisms and mirrors) to alter the imaging optical path, thereby achieving a reduction in the overall height of the camera module while meeting the optical design requirements for a larger effective focal length.

[0005] However, periscope camera modules have a more complex structure, which leads to both increased costs and greater manufacturing difficulty. In terms of optical performance, while periscope camera modules have a relatively large effective focal length, this effective focal length is fixed, meaning their optical performance has relatively poor adjustability. To meet diverse consumer demands for camera modules, multiple camera modules are typically required for electronic devices—that is, multi-camera modules—which not only significantly increases costs but also further complicates manufacturing.

[0006] Therefore, a new type of camera module solution is needed. Summary of the Invention

[0007] One advantage of this application is that it provides a retractable camera module and electronic device, wherein the optical lens of the retractable camera module is retractable relative to its photosensitive chip to switch between an active state and an inactive state. In the active state, the optical lens of the retractable camera module is extended for imaging, and in the inactive state, the optical lens of the retractable camera module is retracted to reduce the overall height of the retractable camera module. In this way, the technical contradiction between height design and a large effective focal length in traditional vertical camera modules is resolved.

[0008] Another advantage of this application is that it provides a retractable camera module and an electronic device, wherein the distance between the optical lens and the photosensitive chip in the retractable camera module can be adjusted by a telescopic component, so that the optical performance of the retractable camera module has better adjustability to adapt to different imaging needs.

[0068] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0069] Exemplary scalable camera module like Figures 1 to 3 As shown, a retractable camera module based on an embodiment of this application is illustrated, wherein the retractable camera module 100 includes: a photosensitive component 10, an optical lens 20 held on the photosensitive path of the photosensitive component 10, and a telescopic component 30 for adjusting the relative positional relationship between the optical lens 20 and the photosensitive component 10.

[0070] More specifically, in this embodiment, the optical lens 20 includes a lens barrel 21 and at least one optical lens 22 mounted within the lens barrel 21. Those skilled in the art will understand that the resolving power of the optical lens 20 is directly proportional to the number of optical lenses 22; that is, the higher the resolving power, the more optical lenses 22 are required. Therefore, preferably, in this embodiment, the optical lens 20 includes multiple optical lenses 22, for example, 4, 5, or 6 optical lenses 22.

[0071] Furthermore, in this embodiment, the optical lens 20 has a large effective focal length, enabling the retractable camera module 100 to be used as a telephoto camera module. More specifically, in this embodiment, the effective focal length of the optical lens 20 ranges from 19mm to 29mm. For example, when the retractable camera module 100 is used to achieve 5x optical zoom, the effective focal length of the optical lens 20 ranges from 19mm to 23mm, preferably from 20mm to 22mm. As another example, when the retractable camera module 100 is used to achieve 10x optical zoom, the effective focal length of the optical lens 20 ranges from 26mm to 30mm, preferably from 27mm to 29mm.

[0072] It is worth mentioning that, in this embodiment, the type of optical lens 20 is not limited to this application; it can be implemented as an integrated optical lens or as a separate optical lens. Specifically, when the optical lens 20 is implemented as an integrated optical lens, the lens barrel 21 has an integrated structure, and multiple optical lenses 22 are assembled within the lens barrel 21. When the optical lens 20 is implemented as a separate lens, the lens barrel 21 includes at least two barrel units, and multiple optical lenses 22 are respectively assembled in the at least two barrel units to form multiple lens units. The multiple lens units are assembled together by active calibration to form the optical lens 20.

[0073] like Figures 1 to 3As shown in this embodiment, the photosensitive component 10 includes: a circuit board 11, a photosensitive chip 12, a bracket 13, and a filter element 14, wherein the circuit board 11 serves as a mounting substrate for the photosensitive component 10. In this embodiment, the photosensitive chip 12 is electrically connected to the circuit board 11 (e.g., the photosensitive chip 12 is electrically connected to the circuit board 11 via leads) so that the circuit board 11 provides the control circuitry and electrical power required for the operation of the photosensitive chip 12. The bracket 13 is disposed on the circuit board 11 to support other components, wherein the bracket 13 has a light window 130 corresponding to at least a photosensitive area of ​​the photosensitive chip 12. For example, in some specific examples of this application, the filter element 14 may be mounted on the bracket 13 so that the filter element 14 is held in the photosensitive path of the photosensitive chip 12. In this way, as external light passes through the filter element 14 to reach the photosensitive chip 12, stray light in the external light can be filtered by the filter element 14 to improve the image quality.

[0074] It is worth mentioning that, in other examples of this application, the filter element 14 can also be mounted on the bracket 13 in other ways. For example, a filter element bracket can be first set on the bracket 13, and then the filter element 14 can be mounted on the filter element bracket. That is, in this example, the filter element 14 can be indirectly mounted on the bracket 13 through other support members. Of course, in other examples of this application, the filter element 14 can also be mounted at other locations of the retractable camera module 100. For example, the filter element 14 can be implemented as a filter film and attached to the surface of a certain optical lens 22 of the optical lens 20. This is not limited to this application.

[0075] To increase the bottom strength of the photosensitive component 10, in some examples of this application, the photosensitive component 10 further includes a base plate 15 disposed on the lower surface of the circuit board 11. For example, a steel plate (i.e., the base plate is a steel plate) may be disposed on the lower surface of the circuit board 11 to strengthen the circuit board 11. Accordingly, the base plate 15 may be configured to have a shape and size consistent with the circuit board 11 to strengthen the circuit board 11 as a whole after being stacked on the lower surface of the circuit board 11. Of course, in some examples of this application, the size of the base plate 15 may be smaller than that of the circuit board 11 to strengthen a local part of the circuit board 11. Of course, in some other examples of this application, the size of the base plate 15 may be larger than that of the circuit board 11, such that after being stacked on the back of the circuit board 11, a portion of the base plate 15 extends from the side of the circuit board 11, wherein the portion of the base plate 15 extending out of the circuit board 11 forms a new mounting substrate. That is, in the embodiments of this application, both the circuit board 11 and the base plate 15 can serve as mounting substrates for the photosensitive component 10, for mounting other parts thereon.

[0076] like Figures 1 to 3 As shown in the embodiment of this application, the telescopic component 30 includes: a first driving element 31, a transmission mechanism 32, and a telescopic sleeve component 33, wherein the first driving element 31, the transmission mechanism 32, and the telescopic sleeve component 33 cooperate to adjust the phase position relationship between the optical lens 20 and the photosensitive component 10.

[0077] Accordingly, in this embodiment, the retractable sleeve assembly 33 is mounted on the mounting substrate of the photosensitive assembly 10. For example, it can be mounted on the circuit board 11, or on the area of ​​the base plate 15 extending out of the circuit board 11. Preferably, in this embodiment, the lower end 332 of the retractable sleeve assembly 33 is mounted on the area of ​​the base plate 15 extending out of the circuit board 11, so that the base plate 15 provides a flat and sufficiently strong mounting surface for the retractable sleeve assembly 33. Furthermore, when the retractable sleeve assembly 33 is mounted on the base plate 15, the central axis of the retractable sleeve assembly 33 is preferably aligned with the central axis of the photosensitive chip 12. That is, preferably, after being mounted on the mounting substrate of the photosensitive assembly 10, the retractable sleeve assembly 33 is also held on the photosensitive path of the photosensitive chip 12.

[0078] Furthermore, such as Figures 1 to 3As shown, in this embodiment, the optical lens 20 is mounted within the retractable sleeve assembly 33 to be held on the light-sensing path of the photosensitive chip 12. That is, in this embodiment, the optical lens 20 and the retractable sleeve assembly 33 are structurally related. Specifically, in... Figures 1 to 3 In the illustrated example, the optical lens 20 is mounted on the upper end 331 of the telescopic sleeve assembly 33 such that when the telescopic sleeve assembly 33 is driven to move telescopically relative to the photosensitive chip 12, the optical lens 20 mounted in the telescopic sleeve assembly 33 can follow the movement of the telescopic sleeve assembly 33 to adjust the relative positional relationship between the optical lens 20 and the photosensitive chip 12.

[0079] It is worth mentioning that, in other examples of this application, the optical lens 20 may be installed at other locations on the retractable sleeve assembly 33, for example, near its upper end 331, or in the middle of the retractable sleeve assembly 33. This is not limited to this application. Furthermore, in some examples of this application, in order to reduce the lateral dimension of the retractable camera module 100, the lens barrel 21 may not be configured for the optical lens 20; instead, the cylinder of the retractable sleeve assembly 33 may be used as the lens barrel 21 for the at least one optical lens 22. This is also not limited to this application.

[0080] Accordingly, in the embodiments of this application, such as Figure 1 and Figure 2 As shown, through the retractable sleeve assembly 33, the optical lens 20 can retractably move relative to the photosensitive chip 12 to switch between a first state and a second state. In the first state, the retractable sleeve assembly 33 is driven to move upward relative to the photosensitive chip 12, thereby causing the optical lens 20 to move upward relative to the photosensitive chip 12, increasing the distance between the optical lens 20 and the photosensitive chip 12. Figure 1 As shown. Figure 2 As shown, in the second state, the retractable sleeve assembly 33 is driven to move downward relative to the photosensitive chip 12, thereby causing the optical lens 20 to move downward relative to the photosensitive chip 12, reducing the distance between the optical lens 20 and the photosensitive chip 12. It should be understood that the first state is the operating state of the retractable camera module 100, and the second state is the non-operating state of the retractable camera module 100.

[0081] In other words, in this embodiment, compared to a traditional vertical camera module, the retractable camera module 100 has two states: a working state (the first state) and a non-working state (the second state). When in the working state, the optical lens 20 extends upward as the retractable sleeve assembly 33 extends, so that the distance between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements (here, the shooting requirements mean that 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 retracts downward as the retractable sleeve assembly 33 retracts, so that the overall height of the retractable camera module 100 is reduced, thereby meeting the size requirements for assembling the retractable camera module 100 in a terminal device. That is, in both working and non-working states, the distance between the optical lens 20 and the photosensitive chip 12 is adjusted by the retractable sleeve assembly 33 so that when in working state, the distance between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements, while when in non-working state, the distance between the optical lens 20 and the photosensitive chip 12 is shortened as much as possible so that the overall height of the retractable camera module 100 is reduced as much as possible.

[0082] More specifically, when the retractable camera module 100 is in operation, the retractable sleeve assembly 33 is driven to extend upwards away from the photosensitive chip 12. At this time, the overall height of the retractable camera module 100 gradually increases. Correspondingly, when the retractable sleeve assembly 33 is fully extended, the overall height of the retractable camera module 100 reaches its maximum value. Here, for ease of description, this maximum value is defined as the maximum height. Furthermore, the height of the retractable camera module 100 represents the distance between the top surface and the bottom surface of the retractable camera module 100.

[0083] Accordingly, when the retractable camera module 100 is in a non-working state, the retractable sleeve assembly 33 is driven to retract downwards in a direction close to the photosensitive chip 12. At this time, the overall height of the retractable camera module 100 gradually decreases. Correspondingly, when the retractable sleeve assembly 33 is fully retracted, the overall height of the retractable camera module 100 reaches its minimum value. Here, for ease of description, this minimum value is defined as the minimum height dimension. Furthermore, 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.

[0084] Specifically, when the retractable camera module 100 is configured as a rear camera module of a terminal device, that is, when the retractable camera module 100 is installed on the back of the terminal device, the minimum height dimension is substantially the same as the thickness dimension of the terminal device. Here, "substantially the minimum height dimension is the same as the thickness dimension of the terminal device" means that when the retractable camera module 100 is installed on the terminal device, its upper surface is flush with or slightly lower than the back of the terminal device. Of course, depending on actual needs, the upper surface of the retractable camera module 100 can also be higher than the back of the terminal device, but generally, for aesthetic reasons, the protruding height should not be too large, and is generally controlled between 0mm and 5mm.

[0085] Accordingly, 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 is extended so that the distance between the optical lens 20 and the photosensitive chip 12 meets the requirements of the optical back focal value for zoom shooting, thereby ensuring image quality. Figure 1 As shown, when in operation, the height of the retractable camera module 100 is significantly greater than the thickness of the module body. It should be understood that, in specific implementations, the maximum and minimum height dimensions depend on the optical zoom ratio requirements of the terminal device.

[0086] Specifically, taking the retractable camera module for achieving 5x optical zoom as an example, the minimum height dimension ranges from 8mm to 11mm, preferably from 9mm to 10mm; the maximum height dimension ranges from 23mm to 26mm, preferably from 24mm to 25mm. Taking the retractable statue module for achieving 10x optical zoom as an example, the minimum height dimension ranges from 9mm to 12mm, preferably from 10mm to 11mm; the maximum height dimension ranges from 28mm to 32mm, preferably from 29mm to 31mm.

[0087] Furthermore, when in working condition, the optical back focal length of the retractable camera module 100 reaches its maximum, and when in non-working condition, the optical back focal length of the retractable camera module 100 reaches its minimum. More specifically, taking the retractable camera module 100 used for 5x optical zoom as an example, when in working condition, the optical back focal length of the retractable camera module 100 ranges from 13mm to 17mm, preferably from 14mm to 16mm; when in non-working condition, the optical back focal length of the retractable camera module 100 ranges from 1mm to 3mm, preferably from 1.5mm to 2.5mm.

[0088] Furthermore, when in operation, the mechanical back focal length of the retractable camera module 100 is at its maximum, and when not in operation, it is at its minimum. Here, the mechanical back focal length of the retractable camera module 100 represents the distance from the cross-section of the lower surface of the last optical lens 22 in the optical lens 20 to the image plane. The value of the mechanical back focal length is quite close to the optical back focal length of the retractable camera module 100, essentially decreasing by about 0.5mm.

[0089] Furthermore, it should be understood that when the retractable camera module 100 is in the working state, the retractable sleeve assembly 33 is driven to extend upwards away from the photosensitive chip 12. At this time, the overall height of the retractable sleeve assembly 33 gradually increases, and correspondingly, when the retractable sleeve assembly 33 is fully extended, its overall height reaches its maximum value. Conversely, when the retractable camera module 100 is in the non-working state, the retractable sleeve assembly 33 is driven to retract downwards towards the photosensitive chip 12. At this time, the overall height of the retractable sleeve assembly 33 gradually decreases, and correspondingly, when the retractable sleeve assembly 33 is fully retracted, its overall height reaches its minimum value. Specifically, in the embodiments of this application, the minimum height of the retractable sleeve assembly 33 ranges from 6mm to 9mm, and the maximum height of the retractable sleeve assembly 33 ranges from 18.6mm to 28.6mm.

[0090] In order for the retractable sleeve assembly 33 to be retractably movable relative to the photosensitive chip 12, a driving force needs to be provided to the retractable sleeve assembly 33. For example... Figure 3 As shown in the embodiment of this application, the driving force of the telescopic sleeve assembly 33 is provided by the first driving element 31. That is, in the embodiment of this application, the telescopic sleeve assembly 33 itself is a passive component and requires an external driving force to drive its movement.

[0091] like Figure 3 As shown, it should be noted that in this embodiment, 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 a clear imaging path must be maintained between the optical lens 20 and the photosensitive chip 12. That is, no other components that obstruct imaging should be present between the optical lens 20 and the photosensitive chip 12. Therefore, in this embodiment, preferably, the first driving element 31 is disposed on the side of the photosensitive chip 12, that is, the first driving element 31 is disposed at a certain position on one side of the photosensitive chip 12, for example, the first driving element 31 is mounted on the circuit board 11 at a certain position on one side of the photosensitive chip 12. To ensure the stability of the first driving element 31, more preferably, the first driving element 31 is mounted on the area of ​​the base plate 15 extending out of the circuit board 11.

[0092] Furthermore, considering that the internal space of the retractable camera module 100 is limited, and that the retractable sleeve assembly 33 houses sensitive and fragile components such as the photosensitive chip 12 and the filter element 14, in some specific examples of this application, the first driving element 31 can be mounted on the outside of the retractable sleeve assembly 33. It should be understood that when the first driving element 31 is mounted on the outside of the retractable sleeve assembly 33, the deployment position of the driving component is also located on the side of the photosensitive chip 12 and relatively further away from it. Of course, in other specific examples of this application, the first driving element 31 can also be mounted inside the retractable sleeve assembly 33, so that the retractable camera module 100 has a more compact structural arrangement.

[0093] It should be understood that the function of the first driving element 31 is to provide a driving force for extending and retracting the retractable sleeve assembly 33. In a specific implementation, the force provided by the first driving element 31 can be directly applied to the retractable sleeve assembly 33 to drive the retractable sleeve assembly 33 to perform an extension and retraction movement relative to the photosensitive chip 12.

[0094] Furthermore, considering the relative positional relationship between the telescopic sleeve assembly 33 and the first driving element 31, the telescopic assembly 30 further includes the transmission mechanism 32 disposed between the first driving element 31 and the telescopic sleeve assembly 33, so as to transmit the driving force generated by the first driving element 31 to the telescopic sleeve assembly 33 through the transmission mechanism 32. Figure 4 As shown.

[0095] Accordingly, 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 first driving element 31 to receive the driving force generated by the first driving element 31, and the power output end 322 is used to output the driving force received by the power receiving end 321.

[0096] In some examples of this 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 first driving element 31 is transmitted through the transmission mechanism 32 and acts on the upper end 331 of the telescopic sleeve assembly 33, so as to drive the other parts of the telescopic sleeve assembly 33 to move by driving the upper end 331, so as to achieve the purpose of driving the telescopic sleeve assembly 33 to perform telescopic movement relative to the photosensitive chip 12.

[0097] It is worth mentioning that, in this embodiment, the optical lens 20 is mounted on the upper end 331 of the telescopic sleeve assembly 33. Therefore, when the power output end 322 of the transmission mechanism 32 acts on the upper end 331 of the telescopic sleeve assembly 33, the telescopic movement of the optical lens 20 and the telescopic sleeve assembly 33 will be relatively more stable and smooth.

[0098] Specifically, in these examples, since the first 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 portion 331 of the retractable sleeve assembly 33 (the upper end portion 331 corresponds to the photosensitive chip 12), in this positional relationship, preferably, the transmission mechanism 32 further includes a steering element 323 for steering the driving force generated by the first driving element 31, the steering element 323 being disposed between the first driving element 31 and the upper end portion 331 of the retractable sleeve assembly 33. It should be understood that by configuring the steering element 323, the driving force generated by the first driving element 31 can be transmitted more smoothly to the upper end portion 331 of the retractable sleeve assembly 33. In specific implementations, the steering element 323 includes, but is not limited to, pulleys, gears, crank connecting rods, etc.

[0099] In some other examples of this application, the power output end 322 may also act on the lower end 332 of the telescopic sleeve assembly 33. That is, the driving force generated by the first driving element 31 is transmitted through the transmission mechanism 32 and acts on the lower end 332 of the telescopic sleeve assembly 33, so as to drive the other parts of the telescopic sleeve assembly 33 to move by driving the lower end 332, so as to achieve the purpose of driving the telescopic sleeve assembly 33 to perform telescopic movement relative to the photosensitive chip 12.

[0100] 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, such as the middle position, the upper middle position, the lower middle position, etc. of the telescopic sleeve assembly 33, and this is not limited to this application. It is worth mentioning that in other examples of this application, the power output end 322 can also act directly on the optical lens 20, that is, the power output end 322 can directly act on the optical lens 20 installed on the upper end 331 of the telescopic sleeve assembly 33.

[0101] It is also worth mentioning that, in other examples of this application, the first driving element 31 can also drive the retractable sleeve assembly 33 to perform a telescopic movement relative to the photosensitive chip 12 in other ways. For example, in some examples of this application, the telescopic assembly 30 further includes an elastic return member 34 disposed between the photosensitive chip 12 and the upper end portion 331 of the retractable sleeve assembly 33, one end of the elastic return member 34 abutting against the upper end portion 331 of the retractable sleeve assembly 33. In its natural state, the elastic return member 34 will spring upward due to its own elasticity, thereby driving the retractable sleeve assembly 33 to extend away from the photosensitive chip 12. Accordingly, in these examples, the first driving element 31 can act on the upper end portion 331 of the retractable sleeve assembly 33 or the optical lens 20 through the transmission mechanism 32 (e.g., a lead wire) to provide a driving force to pull back the retractable sleeve assembly 33 or the optical lens 20. Accordingly, during the process of pulling back the elastic return member 34 via the drive mechanism, the elastic return member 34 is compressed, and the driving force applied by the drive mechanism to the telescopic sleeve assembly 33 or the optical lens 20 is balanced with the elastic force of the elastic return member 34, so that the optical lens 20 can be pulled back and held in a non-operating state. That is, in these examples, the first drive element 31 acts directly on the telescopic sleeve assembly 33 (or the optical lens 20) to drive the telescopic sleeve assembly 33 to retract relative to the photosensitive chip 12, while the extension movement of the telescopic sleeve assembly 33 relative to the photosensitive chip 12 is driven by the elastic return member 34 rather than directly by the first drive element 31.

[0102] Accordingly, in these examples, the first 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 portion 331 of the telescopic sleeve assembly 33 (the upper end portion 331 corresponds to the photosensitive chip 12). In this positional relationship, preferably, the transmission mechanism 32 further includes a steering element 323 for steering the driving force generated by the first driving element 31, the steering element 323 being disposed between the first driving element 31 and the upper end portion 331 of the telescopic sleeve. It should be understood that by configuring the steering element 323, the driving force generated by the first driving element 31 can be transmitted more smoothly to the upper end portion 331 of the telescopic sleeve assembly 33. In specific implementations, the steering element 323 includes, but is not limited to, pulleys, gears, crank connecting rods, etc.

[0103] Furthermore, in these examples, to ensure that the retractable camera module 100 can be kept in a non-operating state, the telescopic assembly 30 may further include a limiting element, wherein when the optical lens 20 is pulled back by the first drive element 31, the limiting element can prevent the retractable sleeve assembly 33 from being bounced back by the elastic return member 34 by restricting the transmission mechanism 32 (e.g., a rope). In specific implementations, the limiting element may be implemented as the first drive element 31 itself, that is, when in a non-operating state, the first drive element 31 can still provide a force to prevent the retractable sleeve assembly 33 from bouncing back. Of course, the limiting element may also be a component disposed outside the first drive element 31, which is not limited to this application.

[0104] It is worth mentioning that, in some examples of this application, the first driving element 31 can directly act on the telescopic sleeve assembly 33, without needing to provide the transmission mechanism 32 between the first driving element 31 and the telescopic sleeve assembly 33, such as... Figure 6 As shown.

[0105] Furthermore, when the retractable camera module 100 is in operation, the optical lens 20 is moved away from the photosensitive chip 12 by the retractable sleeve assembly 33, so that the distance between the optical lens 20 and the photosensitive chip 12 meets the shooting requirements. Correspondingly, because the distance between the optical lens 20 and the photosensitive chip 12 is increased, the imaging optical path between them is lengthened, making it more likely that stray light from the outside will enter the photosensitive chip 12 and affect the image quality.

[0106] To address the issue of stray light affecting imaging, in some examples of this application, the retractable camera module 100 further includes a guide sleeve 40 that extends retractably between the photosensitive chip 12 and the upper end portion 331 of the retractable sleeve assembly 33. The guide sleeve 40 has through-holes 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, through its shape and size design, constrain the imaging light from the optical lens 20 and isolate stray light from outside the guide sleeve from entering the photosensitive chip 12.

[0107] In a specific example of this application, such as Figure 3 As shown, one end of the guide sleeve 40 is fixed to the upper end 331 of the telescopic sleeve assembly 33, and the other end is fixed above the photosensitive chip 12 (e.g., fixed to the bracket 13). In a first state, the telescopic sleeve assembly 33 is driven to move upward relative to the photosensitive chip 12, causing the guide sleeve 40 to be stretched upward relative to the photosensitive chip 12. In a second state, the telescopic sleeve assembly 33 is driven to move downward relative to the photosensitive chip 12, causing the guide sleeve 40 to be shortened downward relative to the photosensitive chip 12. That is, in this specific example, the conductive sleeve can extend and retract together with the telescopic sleeve assembly 33.

[0108] To ensure sufficient imaging light enters the photosensitive chip 12, in this embodiment, preferably, the inner diameter of the guide sleeve 40 gradually increases from top to bottom, and the lower end face of the guide sleeve 40 covers the photosensitive area of ​​the photosensitive chip 12 in the projection area. That is, the lower end face of the guide sleeve 40 can completely cover the photosensitive area of ​​the photosensitive chip 12, thus ensuring that the imaging light entering the photosensitive chip 12 through the guide sleeve 40 can completely cover the imaging area of ​​the photosensitive chip 12.

[0109] Furthermore, such as Figures 1 to 3As shown in this embodiment, the retractable sleeve assembly 33 has a multi-section structure, that is, the retractable sleeve assembly 33 includes multiple nested sleeve units 333. These multiple sleeve units 333 can interact with each other, allowing them to extend or retract relative to the photosensitive chip 12 after being driven. Here, the interaction between the multiple sleeve units 333 indicates that there is force transmission or direct contact between them. Preferably, in this embodiment, adjacent sleeve units 333 are in contact with each other, for example, arranged in a nested manner to form the retractable sleeve assembly 33.

[0110] For example, in some specific examples of this application, the multiple sleeve units 333 of the telescopic sleeve assembly 33 are nested together, and a guide groove 330A is provided between two adjacent sleeve units 333 (e.g., as shown in the example). Figure 6 As shown), the guide groove 330A allows for telescopic movement between the inner and outer sleeve units 333 in the optical axis direction. In other examples of this application, the multiple sleeve units 333 of the telescopic sleeve assembly 33 are interlocked, and a guide rail 330B is provided between adjacent sleeve units 333 (e.g., as shown). Figure 3 As shown), the guide rail 330B allows the inner and outer sleeve units 333 to perform a spiral extension and retraction movement in the optical axis direction. That is, the inner sleeve unit 333 can perform a spiral upward or spiral downward movement under the action of the outer sleeve unit 333.

[0111] In this embodiment, the lower end 332 of the outermost sleeve unit 333 of the multi-sleeve unit 333 forms the lower end 332 of the telescopic sleeve assembly 33, and the upper end 331 of the innermost sleeve unit 333 of the multi-sleeve unit 333 forms the upper end 331 of the telescopic sleeve assembly 33. That is, in this embodiment, the optical lens 20 is mounted on the innermost sleeve unit 333, and the outermost sleeve unit 333 is mounted on the mounting substrate of the photosensitive component 10.

[0112] Accordingly, when the telescopic sleeve assembly 33 is in operation and driven, the outermost sleeve unit 333 is fixed, and the inner sleeve units 333 are extended upward one by one to move away from the photosensitive chip 12, thereby increasing the total optical length between the optical lens 20 and the photosensitive chip 12 to meet shooting requirements.

[0113] In specific implementations, 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, when in operation, 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 innermost sleeve unit 333 is lifted upwards to drive the outer sleeve units 333 to move upwards layer by layer. In this way, the optical lens 20 is moved away from the photosensitive chip 12. In this driving mode, the multi-section sleeve units 333 can be configured with nested inner and outer sections, and adjacent sleeve units 333 can slide up and down.

[0114] Specifically, as mentioned above, in some other examples, when in operation, the power output end 322 of the transmission mechanism 32 in the telescopic assembly 30 directly acts on the lower end 332 of the telescopic sleeve assembly 33. Under the action of the power output end 322, the outermost sleeve unit 333 is rotated to drive the outermost sleeve units 333 to rotate upwards layer by layer. In this way, the optical lens 20 is moved away from the photosensitive chip 12. In this driving mode, the multi-sleeve units 333 can be arranged in a nested configuration with adjacent sleeve units 333 being able to slide spirally.

[0115] It is worth mentioning that, as mentioned above, in this embodiment, the minimum height of the retractable camera module 100 should meet a preset requirement. Therefore, in this embodiment, the height of each segment of the multi-section 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 9.5mm, the height of each segment of the sleeve unit 333 is less than or equal to 9.5mm. Preferably, in this embodiment, each segment of the multi-section sleeve unit 333 has the same height.

[0116] Furthermore, it should be readily understood that in this embodiment, the maximum height of the retractable camera module 100 is determined by the height of each segment of the multi-sleeve unit 333 and the total number of segments of the multi-sleeve unit 333. That is, to a certain extent, the maximum height of the retractable camera module 100 can be controlled by controlling the number of segments of the multi-sleeve unit 333. Specifically, in this embodiment, the number of segments of the multi-sleeve unit 333 is determined based on the quotient of the maximum height of the retractable sleeve assembly 33 and the height of the sleeve unit 333.

[0117] 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, the sleeve units 333 in the multi-section sleeve unit 333 have the same height dimension, 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 unit 333.

[0118] To better understand the design of the height and number of sections of the single sleeve unit 333 of the retractable sleeve assembly 33, a specific example is provided.

[0119] In this specific example, the terminal device requires a height of 9.5mm for the retractable camera module 100. The effective focal length of the optical lens 20 of the retractable camera module 100 is 21mm, and the total optical length of the retractable camera module 100 is also 21mm. The height of the optical lens 20 is 7.3-7.5mm. In this specific example, when in working condition, the required height from the optical lens 20 to the photosensitive chip 12 is 24mm, the height of the optical lens 20 is 7.3mm, and the required height of the retractable camera module 100 is 9.5mm. Therefore, the telescopic component 30 must be provided for the optical lens 20 to ensure that the optical lens 20 is positioned at the appropriate height in working condition, thereby ensuring that the TTL meets the requirements and the retractable camera module 100 can capture images normally.

[0120] In this specific example, the outermost sleeve unit 333 of the retractable sleeve assembly 33 is fixed to the circuit board 11 or other fasteners (e.g., the base plate 15 as described above), and the overall extension length of the retractable sleeve assembly 33 is approximately 24 mm. To ensure that the retractable sleeve assembly 33 can be completely retracted within the retractable camera module 100, the height of each sleeve unit 333 is less than 9.5 mm (it is worth noting that due to the height of components such as the circuit board 11, the height of each sleeve unit 333 may require further control). Therefore, the retractable sleeve assembly 33 must have at least three sections.

[0121] Furthermore, in this embodiment, due to the limited motion control precision of the telescopic component 30, and the varying relative positions between the telescopic camera module 100 and the subject during actual shooting, it is preferable to perform focusing and / or optical image stabilization on the telescopic camera module 100 to improve shooting quality when using it for shooting. That is, in this embodiment, the telescopic camera module 100 further includes a second driving element 50.

[0122] In a specific example of this application, the second driving element 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 relative positional relationship between the optical lens 20 and the image sensor 12 for optical focusing and / or optical image stabilization. Specifically, the second driving element 50 includes, but is not limited to, a voice coil motor, piezoelectric ceramics, etc.

[0123] In another specific example of this application, the second driving element 50 may be configured to act on a certain position of the retractable sleeve assembly 33, for example, acting on the innermost sleeve unit 333 of the retractable sleeve assembly 33, so as to perform optical focusing and / or optical image stabilization by driving the retractable sleeve assembly 33 and the optical lens 20 as a whole.

[0124] In another specific example of this application, the second driving element 50 may be configured to act on the photosensitive chip 12, that is, the second driving element 50 drives the photosensitive chip 12 to move in order to fine-tune the relative positional relationship between the photosensitive chip 12 and the optical lens 20, so as to perform optical focusing and / or optical image stabilization.

[0125] In summary, a retractable camera module 100 based on the embodiments of this application is explained, wherein the optical lens 20 of the retractable camera module 100 is retractable relative to its photosensitive chip 12 to switch between a working state and a non-working state. 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 20 of the retractable camera module 100 is retracted to reduce the overall height of the retractable camera module 100. In this way, the technical contradiction between height design and a large effective focal length in traditional vertical camera modules is resolved.

[0126] Exemplary scaling component 1 Figure 7 The illustration shows a perspective view of a specific example of the telescopic component 30 of the telescopic camera module 100 according to an embodiment of the present application. Figure 8 The illustration shows an exploded perspective view of the telescopic component 30 according to an embodiment of this application. Figure 7 and Figure 8 As shown in this specific example, the telescopic assembly 30 includes: a first driving element 31, a transmission mechanism 32, and an elastic return member 34, wherein the first driving element 31, the transmission mechanism 32, and the elastic return member 34 cooperate to drive the telescopic sleeve assembly 33 to switch between a working state and a non-working state.

[0127] Specifically, such as Figure 7 and Figure 8 As shown, in this specific example, the first driving element 31 is disposed on the side of the photosensitive chip 12. For example, the first driving element 31 is mounted on the circuit board 11 at a certain position on one side of the photosensitive chip 12. To improve the mounting stability of the first driving element 31, in other examples of this application, the first driving element 31 can be mounted on the area of ​​the base plate 15 extending out of the circuit board 11. In some specific examples, when the first driving element 31 is mounted on the area of ​​the base plate 15 extending out of the circuit board 11, the first driving element 31 is located outside the retractable sleeve assembly 33.

[0128] like Figure 7 and Figure 8 As shown, in this specific example, the transmission mechanism 32 includes a lead wire 320A. One end of the lead wire 320A is connected to the first driving element 31 for transmitting the force generated by the first driving element 31. The other end of the lead wire 320A is fixed to the telescopic sleeve assembly 33 or to the optical lens 20 of the telescopic sleeve assembly 33. Preferably, when the other end of the lead wire 320A is fixed to the telescopic sleeve assembly, the other end of the lead wire 320A is fixed to the upper end portion 331 of the telescopic sleeve assembly 33. That is, in this example, the power output end 322 of the transmission mechanism 32 acts on the upper end portion 331 of the telescopic sleeve assembly 33 or the optical lens 20.

[0129] Accordingly, when the retractable camera module 100 is controlled to switch from the working state to the non-working state, the first driving element 31 can be activated to generate a force to pull the lead wire 320A, so as to pull the retractable sleeve assembly 33 or the optical lens 20 downward to the non-working state.

[0130] Furthermore, in order to allow the retractable sleeve assembly 33 to return to its working state, such as... Figure 7 and Figure 8 As shown, in this specific example, the telescopic assembly 30 further includes an elastic return member 34 disposed between the upper end 331 of the telescopic sleeve assembly 33 and the circuit board 11. The elastic return member 34 can be implemented as a spring, leaf spring, or other elastic element.

[0131] Specifically, in such Figure 7 and Figure 8In the illustrated example, one end of the elastic return member 34 is fixed to the circuit board 11, and the other end is fixed to the upper end 331 of the telescopic sleeve assembly 33. In this way, the elastic return member 34 is disposed between the upper end 331 of the telescopic sleeve assembly 33 and the circuit board 11.

[0132] Accordingly, when the retractable camera module 100 is in a non-operating state, the first driving element 31 drives the retractable sleeve assembly 33 (or the optical lens 20) downward via the lead wire 320A as a transmission mechanism 32. During the downward movement, the elastic return member 34 is compressed, and after reaching the corresponding position, the first driving element 31 applies a force to keep the elastic return member 34 in a compressed state. When the retractable camera module 100 is in an operating state, the force applied by the first driving element 31 to the lead wire 320A decreases or disappears, thereby causing the retractable sleeve assembly 33 to extend upward under the elastic force of the elastic return member 34, thereby driving the optical lens 20 mounted on the retractable sleeve assembly 33 to extend upward, increasing the total optical length of the retractable camera module 100. That is, when the retractable camera module 100 is switched from a non-working state to a working state, the compressed elastic recovery member 34 rebounds upward to drive the retractable sleeve assembly 33 to extend upward, so that the optical lens 20 is moved away from the photosensitive chip 12 to meet the shooting requirements.

[0133] It is worth mentioning that, in this specific example, preferably, the elastic recovery member 34 and the lead wire 320A are disposed below the telescopic sleeve assembly 33, that is, below the optical lens 20. With this positioning, the elastic recovery member 34 and the lead wire 320A are reasonably arranged within the space defined by the telescopic sleeve assembly 33, so as to improve the utilization rate of the module and effectively control the overall size (especially the size in the height direction) of the telescopic camera module 100.

[0134] It should be noted that, such as Figure 7 and Figure 8As shown, in this specific example, the optical lens 20 is mounted on the upper end 331 of the retractable sleeve assembly 33 and corresponds to the photosensitive chip 12. The first driving element 31 is located on one side of the photosensitive chip 12. That is, there is a certain lateral distance between the optical lens 20 (the upper end 331 of the retractable sleeve assembly 33) and the first driving element 31. To facilitate the arrangement of the lead wire 320A, in this embodiment, the transmission mechanism 32 further includes at least one pulley 3230 as a steering element 323, so as to reduce the internal space of the module occupied by the lead wire 320A by means of the at least one pulley 3230.

[0135] In this specific example, at least one pulley 3230 is disposed between the first driving element 31 and the photosensitive chip 12. Preferably, the at least one pulley 3230 has the same mounting height as the first driving element 31. For example, when the first driving element 31 is mounted in the area of ​​the circuit board 11 or the base plate 15 extending from the circuit board 11, the at least one pulley 3230 is mounted on the circuit board 11 such that the at least one pulley 3230 has nearly the same mounting height as the first driving element 31. In this way, the lead wire 320A between the first driving element 31 and the at least one pulley 3230 remains nearly horizontal, making the transmission of force smoother.

[0136] In this specific example, the number of at least one pulley 3230 corresponds to the number of leads 320A. That is, preferably, each lead 320A changes direction via a corresponding pulley 3230. The number of leads 320A is greater than or equal to one, for example, two, three, or four. When the number of leads 320A is greater than one, preferably, the leads 320A are arranged uniformly about the optical axis of the retractable camera module 100. Furthermore, the number of leads 320A should not be excessive, as too many leads 320A would occupy more module space, hindering module miniaturization.

[0137] Furthermore, such as Figure 7 and Figure 8 As shown in the embodiment of this application, the multiple sleeve units 333 of the telescopic sleeve assembly 33 are sleeved together, and a guide groove 330A is provided between two adjacent sleeve units 333, which allows the inner and outer sleeve units 333 to move telescopically in the optical axis direction.

[0138] Specifically, in this example, the retractable sleeve assembly 33 has a trapezoidal cross-section, with its dimensions gradually increasing from its upper end 331 to its lower end 332. Preferably, in this specific example, the shape of the elastic return member 34 matches the shape of the retractable sleeve assembly 33; that is, in this specific example, the elastic return member 34 has a structure that is smaller at the top and larger at the bottom. Here, the fact that the shape of the elastic return member 34 matches the shape of the retractable sleeve assembly 33 does not mean that the shape of the elastic return member 34 is identical to the shape of the retractable sleeve assembly 33, but only that the elastic return member 34 has a structure that is larger at the top and smaller at the bottom. For example, in such... Figure 7 and Figure 8 In the illustrated example, the elastic recovery member 34 extends vertically downwards from top to bottom, and then extends outwards and downwards, so that the elastic recovery member 34 has a structure that is larger at the top and smaller at the bottom.

[0139] It is worth mentioning that, in order to keep the retractable camera module 100 in a non-working state, the retractable assembly 30 may further include a limiting element. When the optical lens 20 is pulled back by the first driving element 31 via the lead wire 320A, the limiting element can prevent the retractable sleeve assembly 33 from being bounced back by the elastic return member 34 by restricting the lead wire 320A. In a specific implementation, the limiting element may be implemented as the first driving element 31 itself; that is, when in a non-working state, the first driving element 31 can still provide a force to prevent the retractable sleeve assembly 33 from bouncing back. Of course, the limiting element can also be a component disposed outside the first driving element 31, and this is not limited to this application.

[0140] In summary, the telescopic component 30 based on this specific example of the present application is explained, which, through the cooperation of the first driving element 31, the transmission mechanism 32, and the elastic return member 34, realizes the switching of the telescopic camera module 100 between its working and non-working states. Furthermore, since the elastic return member 34 can rebound quickly, the telescopic camera module 100 can be switched to the working state very quickly, thereby improving work efficiency.

[0141] Exemplary Scalable Component 2 Figure 9 The illustration shows a schematic diagram of another specific example of the telescopic component 30 of the telescopic camera module 100 according to an embodiment of this application. For example... Figure 9 As shown, in this specific example, the telescopic component 30 includes: a first driving element 31 and a transmission mechanism 32, wherein the transmission mechanism 32 includes a gear 324 and a transmission element 325.

[0142] Specifically, the first driving element 31 is disposed on the side of the photosensitive chip 12. For example, the first driving element 31 is mounted on the circuit board 11 at a certain position on one side of the photosensitive chip 12. To improve the mounting stability of the first driving element 31, in other examples of this application, the first driving element 31 can be mounted on the area of ​​the base plate 15 extending out of the circuit board 11. In some specific examples, when the first driving element 31 is mounted on the area of ​​the base plate 15 extending out of the circuit board 11, the first driving element 31 is located outside the retractable sleeve assembly 33.

[0143] like Figure 9 As shown, one end of the conveying member is fixed to the telescopic sleeve assembly 33 (e.g., the upper end 331 of the telescopic sleeve assembly 33), and the other end is tractably connected to the first driving element 31 via the gear 324. That is, in this specific example, the output end of the transmission mechanism 32 acts on the telescopic sleeve assembly 33, for example, the upper end 331 of the telescopic sleeve assembly 33. The gear 324 acts as a steering element 323, which redirects the force generated by the first driving element 31 to drive the conveying member 325 along its transmission direction. It should be understood that the gear 324 allows for a more flexible arrangement of the relative positions of the first driving element 31 and the conveying member 325, thus making fuller use of the internal space of the module.

[0144] It is worth mentioning that in other examples of this application, the other end of the transmission component can also be directly fixed to the optical lens 20, which is not limited to this application.

[0145] It should be noted that, in this specific example, the conveying element extends almost vertically from the upper end 331 of the retractable sleeve assembly 33 and the circuit board 11. Figure 9 There is no number 11 in the text. Accordingly, when the conveyor is actuated, the conveyor 325 can drive the upper end 331 of the telescopic sleeve assembly 33 to move telescopically relative to the photosensitive chip 12 along the transmission direction of the conveyor, so as to achieve the purpose of moving the optical lens 20 away from or closer to the photosensitive chip 12. That is, in this embodiment, the power output end 322 of the transmission mechanism 32 acts on the upper end 33 of the telescopic sleeve assembly 33 or the optical lens 20.

[0146] Furthermore, such as Figure 9As shown in this embodiment, the multiple sleeve units 333 of the telescopic sleeve assembly 33 are interlocked, and a guide groove 330A is provided between two adjacent sleeve units 333, which allows the inner and outer sleeve units 333 to extend and retract in the optical axis direction. In this example, the telescopic sleeve assembly 33 has a trapezoidal cross-section, the size of which gradually increases from its upper end 331 to its lower end 332.

[0147] Specifically, when the retractable camera module 100 is in the working state, the first driving element 31 generates a driving force in a first direction to drive the transmission member 325 upward through the gear 324, thereby driving the upper end 331 of the retractable sleeve assembly 33 or the optical lens 20 upward, so as to increase the distance between the optical lens 20 and the photosensitive chip 12 to meet the shooting requirements. When the retractable camera module 100 is in the non-working state, the first driving element 31 generates a driving force in the opposite direction to the first direction to drive the transmission member 325 downward through the gear 324, thereby driving the upper end 331 of the retractable sleeve assembly 33 or the optical lens 20 downward, so as to reduce the distance between the optical lens 20 and the photosensitive chip 12, thereby reducing the overall height of the retractable camera module 100.

[0148] In a specific implementation, the conveyor 325 can be implemented as a conveyor chain or a conveyor belt. It is worth noting that, in a specific implementation, since the strength of the conveyor belt may not be sufficient to support the telescopic movement of the optical lens 20, a support member can also be provided for the conveyor belt in this specific example. Accordingly, the conveyor belt is mounted on the support member to prevent deformation of the conveyor belt, thereby ensuring that the optical lens 20 can be telescopically extended to the corresponding height.

[0149] It is worth mentioning that, in order to keep the retractable camera module 100 in a non-operating state, the retractable component 30 may further include a limiting element, wherein the limiting element is used to restrict the movement of the conveyor 325. In a specific implementation, the limiting element may be implemented as the first driving element 31 itself, that is, when in a non-operating state, the limiting element can restrict the movement of the conveyor 325. Of course, the limiting element may also be a component disposed outside the first driving element 31, which is not limited to this application.

[0150] In summary, based on this specific example of the present application, the telescopic component 30 is explained, which realizes the switching of the telescopic camera module 100 between its working and non-working states through the cooperation of the first drive element 31, the gear 324 and the transmission element 325.

[0151] Exemplary Scalable Component 3 Figure 10 The illustration shows a schematic diagram of yet another specific example of the telescopic component 30 of the telescopic camera module 100 according to an embodiment of this application. For example... Figure 10 As shown in this specific example, the telescopic component 30 includes: a first driving element 31 and a transmission mechanism 32.

[0152] In particular, such as Figure 10 As shown, the retractable sleeve assembly 33 includes multiple sleeve units 333, which are nested together and have a spiral guide rail 330B between adjacent sleeve units 333. With this structural configuration, when the outermost sleeve unit 333 is driven to rotate in a first direction (e.g., clockwise), the inner sleeve unit 333 moves spirally upward under the guidance of the guide rail 330B; and when the outermost sleeve unit 333 is driven to rotate in a second direction (e.g., clockwise), the inner sleeve unit 333 moves spirally downward under the guidance of the guide rail 330B.

[0153] like Figure 10 As shown, in this specific example, the first driving element 31 is disposed on the side of the photosensitive chip 12. For example, the first driving element 31 is mounted on the circuit board 11 at a position on one side of the photosensitive chip 12. To improve the mounting stability of the first driving element 31, preferably, the first driving element 31 can be mounted on the area of ​​the base plate 15 that extends out of the circuit board 11. In some specific examples, when the first driving element 31 is mounted on the area of ​​the base plate 15 that extends out of the circuit board 11, the first driving element 31 is located outside the retractable sleeve assembly 33.

[0154] like Figure 10 As shown, in this specific example, a transmission mechanism 32 is provided between the first driving element 31 and the lower end 332 of the telescopic sleeve assembly 33, so that the driving force generated by the first driving element 31 is applied to the lower end 332 of the telescopic sleeve assembly 33 through the transmission structure. In this specific example, the transmission mechanism 32 is implemented as a gear transmission mechanism 326, and the lower end 332 of the telescopic sleeve assembly 33 meshes with the gear transmission mechanism 326. That is, in this specific example, the transmission mechanism 32 forms the power output end 322 of the transmission mechanism 32, and the power output end 322 acts on the lower end 332 of the telescopic sleeve assembly 33.

[0155] Specifically, when the retractable camera module 100 is in operation, the first driving element 31 generates a driving force in a first direction, which acts on the lower end 332 of the retractable sleeve assembly 33 through the gear transmission mechanism 326. Correspondingly, under the action of the driving force, the outermost sleeve unit 333 of the retractable sleeve assembly 33 rotates in the first direction, causing the inner sleeve unit 333 to move spirally upward, thereby moving the optical lens 20 away from the photosensitive chip 12 to meet shooting requirements, such as... Figure 11A As shown.

[0156] When the retractable camera module 100 is in a non-working state, the first driving element 31 generates a driving force opposite to the first direction to act on the lower end 332 of the retractable sleeve assembly 33 through the gear transmission mechanism 326. Correspondingly, under the action of the driving force, the outermost sleeve unit 333 of the retractable sleeve assembly 33 rotates in the opposite direction to the first direction, causing the inner sleeve unit 333 to move spirally downwards, thereby bringing the optical lens 20 closer to the photosensitive chip 12 to reduce the distance between the optical lens 20 and the photosensitive chip 12, thus achieving the purpose of reducing the overall height of the retractable camera module 100. Figure 11B As shown.

[0157] It is worth mentioning that, in this specific example, since the gear transmission mechanism 326 has a small structural size, while the lower end 332 of the corresponding meshing telescopic sleeve assembly 33 has a large diameter, this may result in a transmission ratio greater than 1, that is, the rotation speed of the telescopic sleeve assembly 33 is slow, which affects the working efficiency of the telescopic camera module 100.

[0158] To address the aforementioned efficiency issues, in some variations of this specific example, the transmission mechanism 32 can be adjusted to a gear 325 and a worm gear structure. That is, the first driving element 31 drives the gear 325 to rotate, and the gear 325 then drives the worm gear to move. The worm gear acts on the upper end 331 of the optical lens 20 or the telescopic sleeve assembly 33. Through such a transmission mechanism 32, the working efficiency can be improved.

[0159] In summary, based on this specific example of the present application, the telescopic component 30 is explained, which realizes the switching of the telescopic camera module 100 between its working state and non-working state through the cooperation of the first driving element 31, the gear 325 transmission structure and the guide rail 330B disposed on the telescopic sleeve component 33.

[0160] Exemplary Scalable Component 4 Figure 12The illustration shows a schematic diagram of yet another specific example of the telescopic component 30 of the telescopic camera module 100 according to an embodiment of this application. For example... Figure 12 As shown in this specific example, the telescopic component 30 includes: a first driving element 31 and a transmission mechanism 32.

[0161] like Figure 12 As shown in this specific example, the transmission mechanism 32 is a telescopic device 327, which is disposed on the mounting substrate of the photosensitive component 10. One end of the telescopic component 30 is connected to the retractable sleeve assembly 33 (e.g., the upper end 331 of the retractable sleeve assembly 33). Under the action of the first driving element 31, the telescopic device 327 will perform telescopic movement to drive the retractable sleeve assembly 33 to perform telescopic movement, thereby achieving the technical objective of moving away from or closer to the optical lens 20 to the photosensitive chip 12.

[0162] like Figure 12 As shown, in this specific example, the telescopic device 327 includes a base 3271 mounted on the mounting substrate of the photosensitive component 10, and the first driving element 31 is mounted on the base 3271. Further, the telescopic device 327 also includes a transmission assembly 3272 and a telescopic member 3273. The transmission assembly 3272 transmits the driving force generated by the first driving element 31 to the telescopic member 3273. One end of the telescopic member 3273 is coupled to the transmission assembly 3272 to receive the driving force from the transmission assembly 3272. The telescopic member 3273 drives the telescopic sleeve assembly 33 to perform telescopic movement.

[0163] Specifically, such as Figure 12 As shown in this specific example, the transmission assembly 3272 includes transmission elements such as a gear set 3274, a lead screw 3275, and a slider 3276. The gear set 3274 is connected to the output end of the first driving element 31 and is used to transmit and steer the force generated by the first driving element 31. The lead screw 3275 is mounted on the base 3271 and connected to the gear set 3274. The slider 3276 is sleeved on the lead screw 3275. One end of the telescopic member 3273 is connected to the slider. On block 3276, the structure is configured such that when the first driving element 31 is started and begins to work, the first driving element 31 can transmit the force generated by the first driving element 31 to the telescopic member 3273 through the gear set 3274, the lead screw 3275 and the slider 3276, so as to drive the telescopic member 3273 to perform telescopic movement, thereby driving the telescopic sleeve assembly 33 to perform telescopic movement, so as to achieve the purpose of adjusting the distance between the optical lens 20 and the photosensitive chip 12.

[0164] Accordingly, such as Figure 12 As shown, in this specific example, the telescopic member 3273 includes multiple connecting rods 3277 that are hinged to each other, wherein the multiple connecting rods 3277 are hinged to each other to form multiple hinge points 3278, wherein the uppermost connecting rod 3277 is fixed to the upper end 331 of the telescopic sleeve assembly 33, and the lowermost connecting rod 3277 is fixed to the slider 3276.

[0165] Accordingly, when in operation, the first driving element 31 generates a driving force in a first direction. This driving force is transmitted through the transmission assembly 3272 and drives the slider 3276 to slide in the first direction. The sliding slider 3276 can drive the multiple connecting rods 3277 of the telescopic member 3273 to pivot, thereby causing the telescopic sleeve assembly 33 to extend upwards. This increases the distance between the optical lens 20 and the photosensitive chip 12 to meet the shooting requirements. Figure 13A As shown.

[0166] When not in operation, the driving force is generated in the opposite direction to the first driving force. This driving force is transmitted through the transmission assembly 3272 and drives the slider 3276 to slide in the opposite direction to the first direction. The sliding slider 3276 drives the multiple connecting rods 3277 of the telescopic member 3273 to pivot, thereby retracting the telescopic sleeve assembly 33 and the optical lens 20 downwards, thus reducing the overall height of the telescopic camera module. Figure 13B As shown.

[0167] Preferably, in this specific example, the number of the plurality of hinge points 3278 of the telescopic member 3273 is consistent with the number of sleeve units 333 of the telescopic sleeve assembly 33. More preferably, the plurality of hinge points 3278 are respectively connected to their respective corresponding sleeve units 333. Taking the example that the telescopic member 3273 includes 3 hinge points 3278 and the telescopic sleeve assembly 33 includes 3 sleeve units 333, wherein the 3 hinge points 3278 are respectively fixed to the 3 sleeve units 333 of the telescopic sleeve assembly 33.

[0168] In summary, based on this specific example of the present application, the telescopic component 30 is explained, which realizes the switching of the telescopic camera module 100 between its working state and non-working state through the cooperation of the first driving element 31 and the telescopic component 30.

[0169] Specific examples Figure 14AThe illustration shows a perspective cross-sectional view of yet another specific example of the retractable camera module according to an embodiment of this application. Figure 14B The illustration shows yet another specific example of the retractable camera module according to an embodiment of this application. (See diagram below.) Figure 14A and Figure 14B As shown, in this specific example, the retractable camera module 100 includes: a photosensitive component 10, an optical lens 20 held on the photosensitive path of the photosensitive component 10, and a telescopic component 30 configured to adjust the relative positional relationship between the optical lens 20 and the photosensitive component 10.

[0170] like Figure 14A and Figure 14B As shown, in this specific example, the photosensitive assembly 10 includes: a circuit board 11, a photosensitive chip 12, a bracket 13, and a filter element 14. The photosensitive chip 12 is electrically connected to the circuit board 11 (e.g., the photosensitive chip 12 is electrically connected to the circuit board 11 via leads) to provide the control circuitry and electrical power required for the operation of the photosensitive chip 12 via the circuit board 11. The bracket 13 is disposed on the circuit board 11 to support other components, and the bracket 13 has a light window 130 corresponding to at least a photosensitive area of ​​the photosensitive chip 12. For example, in some specific examples of this application, the filter element 14 may be mounted on the bracket 13 such that the filter element 14 is held in the photosensitive path of the photosensitive chip 12. Thus, as external light passes through the filter element 14 to reach the photosensitive chip 12, stray light in the external light can be filtered by the filter element 14 to improve image quality. In this specific example, the bracket 13 is implemented as a molded bracket integrally formed on the circuit board 11 to cover at least a portion of the circuit board 11.

[0171] To increase the bottom strength of the photosensitive component 10, in this specific example, the photosensitive component 10 further includes a base plate 15 disposed on the lower surface of the circuit board 11. For example, a steel plate (i.e., the base plate 15 is a steel plate) may be disposed on the lower surface of the circuit board 11 to strengthen the circuit board 11. In this specific example, the size of the base plate 15 is larger than that of the circuit board 11, such that after being stacked on the back of the circuit board 11, a portion of the base plate 15 extends from the side of the circuit board 11, wherein the portion of the base plate 15 extending out of the circuit board 11 forms a mounting substrate.

[0172] like Figure 14A and Figure 14BAs shown in the embodiment of this application, the telescopic component 30 includes: a first driving element 31, a transmission mechanism 32, and a telescopic sleeve component 33, wherein the first driving element 31, the transmission mechanism 32, and the telescopic sleeve component 33 cooperate to adjust the phase position relationship between the optical lens 20 and the photosensitive component 10.

[0173] In this specific example, the retractable sleeve assembly 33 is disposed on the base plate 15, wherein the optical lens 20 is fixed within the retractable sleeve assembly 33. Specifically, in this example, the retractable sleeve assembly 33 has a lower end portion 332 and an upper end portion 331 relative to the lower end portion 332, and the optical lens 20 is mounted on the upper end portion 331 of the retractable sleeve assembly 33. Accordingly, the first driving element 31 is configured to drive the retractable sleeve assembly 33 to retract relative to the photosensitive chip 12 along the photosensitive path. Therefore, in this specific example, through the first driving element 31 and the retractable sleeve assembly 33, the optical lens 20 is retractably movable relative to the photosensitive chip 12 to switch between an active state and an inactive state. When in the active state, the retractable sleeve assembly 33 is driven to extend upward relative to the photosensitive chip 12, thereby causing the optical lens 20 to move upward relative to the photosensitive chip 12, thus increasing the distance between the optical lens 20 and the photosensitive chip 12. When in the inactive state, the retractable sleeve assembly 33 is driven to retract downward relative to the photosensitive chip 12, thereby causing the optical lens 20 to move downward relative to the photosensitive chip 12, thus decreasing the distance between the optical lens 20 and the photosensitive chip 12.

[0174] like Figure 15 and Figure 16 As shown, in this specific example, the retractable sleeve assembly 33 includes: a fixed portion 336 disposed on the base plate 15; a plurality of movable portions 337 embedded in the fixed portion 336 and nested within each other; and at least one support frame 338 disposed between each pair of adjacent movable portions 337 to structurally reinforce the corresponding movable portion 337. Specifically, in this specific example, the fixed portion 336 forms the lower end portion 332 of the retractable sleeve assembly 33, and the innermost movable portion 337 of the plurality of movable portions 337 forms the upper end portion 331 of the retractable sleeve assembly 33. That is, in this specific example, the optical lens 20 is fixed to the innermost movable portion 337.

[0175] like Figure 14A , 14B , Figure 15 and Figure 16 As shown, in this specific example, the fixing part 336 includes a housing 3361 disposed on the base plate 15 and a first sleeve 3362 embedded within the housing 3361, wherein the first sleeve 3362 has a first helical guide rail 3363 recessed in its inner surface, and a first guide groove 3364 recessed in its inner surface and extending vertically. Figure 14A , 14B , Figure 15 and Figure 16 As shown, the plurality of movable parts 337 include a first movable part 3371 embedded in the fixed part 336, wherein the first driving element 31 is configured to act on the first movable part 3371 so that the first movable part 3371 moves spirally upward or downward along the first helical guide rail 3363.

[0176] More specifically, the first movable part 3371 includes a second sleeve 3372 tractably connected to the first drive element 31. The second sleeve 3372 has a first guide head 3373 protruding from its outer surface. When the second sleeve 3372 is embedded in the first sleeve 3362, the first guide head 3373 is fitted into the first helical guide rail 3363, so that after the second sleeve 3372 is driven by the first drive element 31, the second sleeve 3372 moves spirally upward or downward along the first helical guide rail 3363.

[0177] In this specific example, such as Figure 14A , 14B , Figure 15 and Figure 16 As shown, the second sleeve 3372 has an annular rack 3374 formed on its outer surface, and the first sleeve 3362 also has a receiving groove 3365. The telescopic assembly 30 further includes a gear post 320D disposed in the receiving groove 3365. The gear post 320D meshes with the annular rack 3374 of the second sleeve 3372. The force provided by the first driving element 31 acts on the gear post 320D to transmit the force to the second sleeve 3372 through the gear post 320D as a transmission mechanism 32. In this specific example, the first driving element 31 can be implemented as a stepper motor.

[0178] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16As shown, in this specific example, the first movable part 3371 further includes a third sleeve 3375 embedded in the second sleeve 3372, wherein the third sleeve 3375 has a second helical guide rail 3376 recessed on its inner surface, and a second guide groove 3377 recessed on its inner surface and extending vertically.

[0179] Specifically, in this particular example, the outer shell 3361 is made of metal, and the first sleeve 3362 is made of plastic. That is, the outer shell 3361 is a metal shell 3361, and the first sleeve 3362 is a plastic sleeve. Here, when the outer shell 3361 is implemented as a metal shell 3361, the metal shell 3361 forms a signal shield, which helps to prevent external noise from interfering with imaging. Furthermore, the first sleeve 3362 embedded in the metal shell 3361 can strengthen the structural strength of the metal shell 3361. Also, when the first sleeve 3362 is implemented as a plastic sleeve, it can reduce the overall weight of the retractable sleeve assembly 33. Of course, in other examples of this application, the outer shell 3361 and the first sleeve 3362 can also be made of other materials. The materials used to make the outer shell 3361 and the first sleeve 3362 can be the same or different, and this is not limited to this application.

[0180] Specifically, in this particular example, the second sleeve 3372 is made of metal, and the third sleeve 3375 is made of plastic. That is, the second sleeve 3372 is a metal sleeve, and the third sleeve 3375 is a plastic sleeve. Here, when the second sleeve 3372 is implemented as a metal sleeve, the second sleeve 3372 is exposed to the outside environment in the working state of the retractable camera module 100. Therefore, the second sleeve 3372 made of metal can extend its lifespan, and the second sleeve 3372 made of metal has relatively high strength. Correspondingly, the third sleeve 3375 embedded in the second sleeve 3372 can strengthen the structural strength of the second sleeve 3372, and when the third sleeve 3375 is implemented as a plastic sleeve, it can reduce the overall weight of the first movable part 3371. Furthermore, when the third sleeve 3375 is made of plastic, it is easier to process the second helical guide rail 3376 on its inner surface.

[0181] Of course, in other examples of this application, the second sleeve 3372 and the third sleeve 3375 may also be made of other materials. The outer shell 3361 and the first sleeve 3362 may be made of the same material or different materials. This is not limited by this application.

[0182] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16 As shown in this specific example, the at least one support frame 338 includes a first support frame 3381 embedded in the first sleeve 3375. The first support frame 3381 has a second guide head 3382 formed at its lower end 332. When the first support frame 3381 is embedded in the first sleeve 3362, the second guide head 3382 is engaged in the first guide groove 3364 of the first sleeve 3362, so that when the first support frame 3381 is moved upward or downward with the first movable part 3371, the first support frame 3381 moves vertically upward or downward along the first guide groove 3364.

[0183] Here, when the first support frame 3381 moves synchronously upward or downward along the first guide groove 3364 with the first movable part 3371, the first support frame 3381 embedded in the first movable part 3371 can provide sufficient support strength for the first movable part 3371 to ensure the stability of the telescopic sleeve assembly 33 during the extension or retraction process.

[0184] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16 As shown, in this specific example, the first support frame 3381 has a third guide groove 3383 formed through its side surface and extending vertically, and a movable space 3384 formed through its side surface. Figure 16 As shown, the third guide groove 3383 is formed through the inner and outer sides of the first support frame 3381, and in this specific example, the third guide groove 3383 has a U-shaped structure. Figure 16 As shown, the movable space 3384 is formed through the inner and outer sides of the first support frame 3381. Specifically, in this specific example, the movable space 3384 is enclosed by the upper edge, lower surface and inner wall of the first support frame 3381.

[0185] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16As shown in this specific example, the plurality of movable parts 337 further include a second movable part 3391. The second movable part 3391 includes a fourth sleeve 3392. The fourth sleeve 3392 has a third guide head 3393 protruding from its outer surface. The fourth sleeve 3392 is embedded in the first support frame 3381, and the third guide head 3393 passes through the third guide groove 3383 and is fitted into the second helical guide rail 3376 of the third sleeve 3375. When the third sleeve 3375 is driven to move helically upward or downward, the fourth sleeve 3392 is driven to move vertically upward or downward along the second helical guide rail 3376 and under the action of the third guide groove 3383.

[0186] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16 As shown, in this specific example, the second movable part 3391 further includes a fifth sleeve 3394, which has a fourth guide head 3395 protruding from its outer surface and a third helical guide rail 3396 recessed from its inner surface. The fifth sleeve 3394 is embedded in the fourth sleeve 3392 and the fourth guide head 3395 is movably supported in the movable space 3384 of the first support frame 3381. When the first support frame 3381 is driven to move vertically upward or downward, the fifth sleeve 3394 is driven by the first support frame 3381 to move helically upward or downward.

[0187] Specifically, in this particular example, the fourth sleeve 3392 is made of metal, and the fifth sleeve 3394 is made of plastic. That is, the fourth sleeve 3392 is a metal sleeve, and the fifth sleeve 3394 is a plastic sleeve. Here, when the fourth sleeve 3392 is implemented as a metal sleeve, it is exposed to the outside world in the working state of the retractable camera module 100. Therefore, the fourth sleeve 3392 made of metal can extend its lifespan, and the fourth sleeve 3392 made of metal has relatively high strength. Correspondingly, the fifth sleeve 3394 embedded in the fourth sleeve 3392 can strengthen the structural strength of the fourth sleeve 3392, and when the fifth sleeve 3394 is implemented as a plastic sleeve, it can reduce the overall weight of the second movable part 3391. Furthermore, when the fifth sleeve 3394 is made of plastic, it is easier to process the third helical guide rail 3396 on its inner surface.

[0188] Of course, in other examples of this application, the second sleeve 3372 and the third sleeve 3375 may also be made of other materials. The outer shell 3361 and the first sleeve 3362 may be made of the same material or different materials. This is not limited by this application.

[0189] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16 As shown, in this specific example, the at least one support frame 338 includes a second support frame 3385 embedded within the fifth sleeve 3394. The second support frame 3385 has a fifth guide head 3386 protruding from its outer surface. When the second support frame 3385 is embedded within the fifth sleeve 3394, the fourth guide head 3395 is movably disposed within the third guide groove 3383 of the first support frame 3381. Accordingly, when the fifth sleeve 3394 is driven by the first support frame 3381 to move spirally upward or downward, the second support frame 3385 is driven by the fifth sleeve 3394 and moves vertically upward or downward under the action of the third guide groove 3383.

[0190] It should be understood that when the second support frame 3385 is driven by the fifth sleeve 3394 and moves vertically upward or downward under the action of the third guide groove 3383, the second support frame 3385 embedded in the second movable part 3391 can provide sufficient support strength for the second movable part 3391 to ensure the stability of the telescopic sleeve assembly 33 during the extension or retraction process.

[0191] Furthermore, such as Figure 14A , 14B , Figure 15 and Figure 16As shown, in this specific example, the second support frame 3385 has a vertically extending guide portion 3387 protruding from its outer surface. The third movable portion 3411 includes a sixth sleeve 3412 fitted between the second support frame 3385 and the fifth sleeve 3394. The sixth sleeve 3412 has a sixth guide head 3413 protruding from its outer surface and a vertically extending guide groove 3414 recessed from its inner surface. When the sixth sleeve 3412 is fitted between the second support frame 3385 and the fifth sleeve 3394, the sixth guide head 3413 is fitted into the third helical guide rail 3396 of the fifth sleeve 3394, and the guide groove 3414 is fitted into the guide portion 3387. Correspondingly, when the fifth sleeve 3394 is driven to move spirally upward or downward by the first support frame 3381, the sixth sleeve 3412 is driven to move vertically upward or downward along the third spiral guide rail 3396 and under the action of the guide part 3387 and the guide groove 3414.

[0192] Preferably, in this specific example, the sixth sleeve 3412 is made of metal. Of course, in other examples of this application, the sixth sleeve 3412 may also be made of other materials, such as plastic. It is worth noting that in this specific example, when in operation, the sixth sleeve 3412 forms the upper end portion 331 of the telescopic sleeve assembly 33.

[0193] It is also worth mentioning that, although the above-described telescopic sleeve assembly 33 includes one fixed part 336, three movable parts 337 and two support frames 338 as an example, those skilled in the art should understand that in other specific embodiments of this specific example, the telescopic sleeve assembly 33 may also include a greater number of movable parts 337 and a greater number of support frames 338, which is not limited to this application.

[0194] As described above, in this specific example, the first driving element 31 is implemented as a stepper motor, and the transmission mechanism 32 is implemented as a gear 320D, so that the first movable part 3371 of the retractable sleeve assembly 33 is driven through the cooperation between the stepper motor and the gear 320D. However, in specific implementations, since the stepper motor and gear 320D have a large structural volume, installing them inside the retractable sleeve assembly 33 may cause the overall size of the retractable camera module 100 to be too large, which cannot meet the current trend of miniaturization of module structure. Furthermore, since the efficiency of the stepper motor in driving the retractable sleeve assembly 33 is low when it is working, it may also be accompanied by motor noise. Therefore, in other specific embodiments of this specific implementation, the first driving element 31 may also be a ring ultrasonic motor.

[0195] Specifically, the annular ultrasonic motor includes a stator 51 and a mover 52. The stator 51 is made by connecting an annular piezoelectric ceramic sheet to an annular metal plate. The electrode arrangement and excitation method of the annular piezoelectric ceramic sheet can generate traveling waves in the stator 51. The annular metal plate is made into a comb shape to increase the amplitude of the wave.

[0196] It has been verified that replacing the stepper motor with a ring ultrasonic motor as the power source for the telescopic sleeve assembly 33 can improve driving efficiency and make the drive quieter.

[0197] Specifically, such as Figure 17 As shown, in this specific example, the bottom of the second sleeve 3372 is mounted on the mover 52 of the annular ultrasonic motor, wherein the stator 51 of the annular ultrasonic motor is mounted on the base plate 15. Accordingly, when current is applied to the annular ultrasonic motor, the mover 52 of the annular ultrasonic motor can rotate to drive the first movable part 3371 of the retractable sleeve assembly 33 connected thereto (more specifically, the second sleeve 3372 of the first movable part 3371). In particular, in this specific example, the annular ultrasonic motor has a reinforcing structure on the outside of its stator 51, more specifically, a boss on the outside of its stator 51, which can be fixed to other parts of the retractable sleeve assembly 33 to improve the support strength of the stator 51 of the annular ultrasonic motor.

[0198] Furthermore, such as Figure 18 and 19 As shown, in this specific example, the circuit board 11 has a circular circuit board body 111 and a flexible board connection plate 112 electrically connected to the circuit board body 111, and the circuit board 11 further includes terminals 113 formed at the periphery of the circuit board 11. Figure 18 and 19 As shown, in this specific example, the retractable camera module 100 further includes a second driving element 50 for driving the photosensitive component 10 to perform optical focusing and / or optical image stabilization.

[0199] In this specific example, the pins of the second drive element 50 are electrically connected to the terminal 113 to provide the second drive element 50 with the power required for operation via the circuit board 11. Figure 19As shown, in this specific example, the second driving element 50 includes a fixing part 336 and a driving part, wherein the photosensitive component 10 is disposed on the driving part. Here, the driving part has an annular mounting cavity; therefore, in this specific embodiment, the circuit board body 111 is implemented as an annular structure so that the shape of the circuit board 11 is adapted to the mounting cavity of the driving part.

[0200] Accordingly, after the second driving element 50 is turned on, the driving unit can carry the photosensitive component 10 to move along its set photosensitive path for optical focusing, and / or adjust its pose in the plane set by the photosensitive component 10 for optical image stabilization.

[0201] It is worth mentioning that, in this specific example, since the second driving element 50 only needs to drive the photosensitive component 10 to move, the required driving force is small, that is, the structure of the second driving element 50 can be miniaturized. In specific implementations, the second driving element 50 can be a ball motor, an SMA motor, or an ultrasonic motor, and its specific selection is not limited by this application.

[0202] Furthermore, such as Figure 14A As shown, in this specific implementation, the outer shell 3361 of the telescopic sleeve assembly 33 is provided with an installation space for installing the flexible board connecting plate 112, that is, an installation gap is reserved at the corresponding position of the outer shell 3361 for leading out the flexible board connecting plate 112.

[0203] It is worth mentioning that, in this specific example, the second driving element 50 may only have a focusing function or only have an optical image stabilization function, which is not limited by this application.

[0204] In summary, based on this specific example of the retractable camera module 100, when in operation, the retractable sleeve assembly 33 extends upward under the action of the first driving element 31 to move the optical lens 20 away from the photosensitive component 10, ensuring that the distance between the optical lens 20 and the photosensitive component 10 meets the requirements for telephoto shooting. Furthermore, to achieve better imaging of the captured object, the second driving element 50 of the retractable camera module 100 can drive the photosensitive component 10 to change its relative positional relationship with the optical lens 20 for optical focusing and / or optical image stabilization. When the retractable camera module 100 is not in operation, the retractable sleeve assembly 33 retracts downward under the action of the first driving element 31, causing the optical lens 20 to retract downward, thereby reducing the overall height of the retractable camera module 100.

[0205] Exemplary electronic devices According to another aspect of this application, an electronic device is also provided.

[0206] Figure 20 The illustration shows a schematic diagram of an electronic device according to an embodiment of this application. For example... Figure 20 As shown, the electronic device 200 according to an embodiment of this application includes an electronic device body 210 and a retractable camera module 100 as described above, assembled on the electronic device body 210. Specifically, the minimum height dimension of the retractable sleeve assembly 33 is less than or equal to the thickness dimension of the electronic device 200.

[0207] In a specific implementation, the retractable camera module 100 can be deployed on the back of the electronic device body 210 as a rear-facing camera module. Alternatively, it can be positioned at the front of the electronic device body 210 as a front-facing camera module. The specific installation location of the retractable camera module 100 on the electronic device body 210 is not limited by this application.

[0208] In particular, compared to conventional upright camera modules, the retractable camera module 100, in its working state, can extend its optical lens 20 to increase its total optical length until it meets the shooting requirements.

[0209] Figure 21 Another schematic diagram of an electronic device 200 according to an embodiment of this application is shown. Figure 21 As shown, the electronic device 200 according to an embodiment of this application includes an electronic device body 210, a retractable camera module 100 assembled on the electronic device body 210 as described above, and a second camera module 220 assembled on the electronic device body 210. In particular, compared to the retractable camera module 100, the second camera module 220 has a relatively smaller effective focal length.

[0210] That is, in such Figure 21 In the illustrated electronic device 200, the electronic device 200 is configured with a multi-camera module, that is, the retractable camera module 100 is used together with an existing short-focus camera module as the image sensor of the electronic device 200. During operation, the retractable camera module 100 and the second camera module 220 can cooperate with each other to provide richer imaging functions.
