Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a camera module and electronic device. Background Technology

[0002] As the performance requirements of mobile phone camera modules increase, better image quality is needed. Existing camera modules are not waterproof and dustproof, allowing moisture or dust particles from the outside to enter the internal cavity of the camera module, affecting the image quality. Summary of the Invention

[0003] This application provides a camera module and an electronic device including the camera module. The camera module provided in this embodiment is waterproof, dustproof, and has good photo quality.

[0004] In a first aspect, a camera module is provided. The camera module includes a module circuit board, a first lens assembly, an airbag, and a housing. The module circuit board is located on the light-emitting side of the first lens assembly. The airbag surrounds the first lens assembly. A first end of the airbag is connected to the light-incident side of the first lens assembly, and a second end of the airbag is connected to the module circuit board. The airbag seals the space between the first lens assembly and the module circuit board. When the first lens assembly moves away from the module circuit board, the airbag stretches. When the first lens assembly moves towards the module circuit board, the airbag contracts. The housing is fixed to the module circuit board and sleeved around the airbag.

[0005] Understandably, when the camera module switches from a non-shooting state to a shooting state, and the first lens assembly moves away from the module circuit board (i.e., when the camera module rises), the airbag extends, and some of the gas between the airbag and the first lens assembly enters the inner cavity of the first lens assembly. When the camera module switches from a shooting state to a non-shooting state, and the first lens assembly moves closer to the module circuit board (i.e., when the camera module descends), the airbag contracts, and the gas that entered the inner cavity of the first lens assembly returns to the space between the airbag and the first lens assembly. This ensures that the air pressure inside the airbag remains balanced during the movement of the first lens assembly, and there is no pressure difference resistance during the lifting and lowering of the first lens assembly, thus ensuring smooth lifting and lowering of the first lens assembly.

[0006] This application utilizes an airbag within the camera module to seal the first lens assembly, preventing external moisture and dust particles from entering the inner cavity of the first lens assembly. This prevents external moisture from entering and causing condensation on the lenses, and also prevents external dust particles from entering and adhering to the lenses, thus avoiding any impact on the camera module's image quality. The camera module of this application produces excellent image quality. Furthermore, the airbag in this embodiment completely encloses the first lens assembly, resulting in better waterproofing and dustproofing of the camera module.

[0007] Meanwhile, the inner cylinder of the housing is sleeved around the airbag and fixed to the module circuit board. In other words, the airbag is located inside the space enclosed by the housing and the module circuit board. Compared to placing the airbag between the housing and the module circuit board, the airbag will not protrude outwards from the housing when it expands and contracts. Instead, it will be contained within the space between the housing and the module circuit board. This helps protect the airbag, prevents it from being exposed outside the camera module and rubbing against other components, avoids friction damage to the airbag, and extends the service life of the airbag.

[0008] In one possible implementation, the first lens assembly includes a first lens bracket, which includes an incident light end and an emitting light end opposite to the incident light end. A protrusion is provided on the outer side of the first lens bracket, near the incident light end, and a first end is fixed to the protrusion. This application provides a protrusion on the first lens bracket near the incident light end to facilitate the connection of the first end of the airbag to the first lens bracket. Simultaneously, the protrusion increases the contact area between the first end of the airbag and the first lens bracket, making the first end of the airbag more securely connected to the first lens bracket.

[0009] In one possible implementation, the protrusion has an installation space along its periphery, and the first end of the airbag is fixed to the installation space. On the one hand, the installation space can limit the first end of the airbag, ensuring that the first end of the airbag is stably fixed to the protrusion. On the other hand, the first end of the airbag and the protrusion have an overlapping portion on the Z-axis, which is beneficial to achieving a thinner camera module.

[0010] In one possible implementation, the first end is fixed to the installation space via in-mold injection molding, ensuring the connection strength between the airbag and the first lens group support, as well as ensuring a seamless connection between the airbag and the first lens group support. Of course, in other implementations, the first end of the airbag can also be fixed to the protrusion by means of adhesive or other methods.

[0011] In one possible implementation, the camera module further includes a fixing bracket, which includes a holding part and a fixing part connected to the holding part. The fixing part is fixed to the module circuit board, and the holding part is connected to the side of the second end facing away from the module circuit board.

[0012] In other words, this implementation connects the second end of the airbag to the module circuit board via a fixed bracket. This is more convenient than directly connecting the second end of the airbag to the module circuit board, effectively improving product assembly efficiency. Simultaneously, the second end of the airbag is essentially clamped between the fixed bracket and the module circuit board. Compared to adhesive bonding, the second end of the airbag is more securely fixed to the module circuit board, extending the lifespan of the camera module.

[0013] Furthermore, the fixing bracket effectively prevents the second end of the airbag from being stretched during extension and retraction. Understandably, when the camera module switches from a non-shooting state to a shooting state, the airbag is stretched, and the second end of the airbag will experience a pulling force towards the first end. Repeated stretching can affect the adhesion between the second end and the module circuit board. This application addresses this by providing a fixing bracket, where the holding part of the fixing bracket presses the second end against the module circuit board, preventing the tensile force from each stretching of the airbag from being transmitted to the second end, ensuring the adhesive strength between the second end and the module circuit board, and extending the lifespan of the airbag.

[0014] In one possible implementation, the pressure-holding part includes a pressure groove, and the second end is fixed within the pressure groove. It is understood that the pressure-holding part, by providing a pressure groove, avoids directly pressing the pressure-holding part against the second end of the airbag, as the pressure force would damage the second end. The pressure groove accommodates and fixes the second end, preventing damage to the second end of the airbag. Of course, in other embodiments, the pressure-holding part may not include a pressure groove, and the pressure-holding part may directly press against the second end of the airbag.

[0015] In one possible implementation, when the airbag contracts, it is in its natural state, and the airbag is corrugated in the direction of movement of the first lens assembly. It is understood that in this embodiment, by shaping the contracted (natural) airbag into a regular corrugated shape, it is ensured that the airbag does not deform excessively during contraction, preventing it from deforming and protruding and getting stuck between adjacent components of the camera module, thus affecting the normal shooting of the camera module.

[0016] In one possible implementation, the housing includes an inner cylinder and an outer cylinder. The inner cylinder is fixed to the module circuit board and disposed on the outer periphery of the airbag. The outer cylinder is sleeved outside the inner cylinder. The camera module also includes a driving component for driving the outer cylinder and moving it relative to the inner cylinder in the direction of movement of the first lens assembly, so as to avoid the outer cylinder obstructing the movement of the first lens assembly.

[0017] In one possible implementation, the inner cylinder includes a positioning groove, and the fixing bracket portion is housed within the positioning groove. It is understood that a limiting relationship can be formed between the positioning groove of the inner cylinder and the fixing portion of the fixing bracket, allowing the inner cylinder to be quickly installed on the module circuit board. Simultaneously, the fixing bracket and the inner cylinder have an overlapping portion along the Z-axis, which is beneficial for the thinning of the camera module.

[0018] In one possible implementation, the drive assembly includes a drive unit, a screw, and a slider. The screw is fixed to the outside of the inner cylinder, and the slider includes a first part and a second part. The first part is rotatably connected to the screw, and the second part is connected to the outer cylinder. The drive unit is used to drive the screw to rotate and control the outer cylinder to move relative to the inner cylinder in the direction of movement of the first mirror assembly.

[0019] In one possible implementation, the drive assembly further includes a spring, which is elastically connected between the second part and the outer cylinder. This embodiment, by placing a spring between the second part and the outer cylinder, indirectly pushes or pulls the outer cylinder upwards or downwards, resulting in smoother movement of the outer cylinder during ascent or descent compared to a direct connection between the second part and the outer cylinder.

[0020] In one possible implementation, the camera module further includes a second lens assembly, which is located between the first lens assembly and the module circuit board.

[0021] In one possible implementation, the camera module further includes a photosensitive chip, which is fixed to and electrically connected to the module circuit board. The photosensitive chip is used to acquire optical images and convert them into electrical signals.

[0022] Secondly, an electronic device is provided. The electronic device includes a housing and the aforementioned camera module, with the camera module disposed within the housing. The electronic device equipped with the aforementioned camera module exhibits good image capture performance. Attached Figure Description

[0055] Please see Figure 1 and Figure 2 , Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 100 from another angle.

[0056] For ease of description, the width direction of electronic device 100 is defined as the X-axis. The length direction of electronic device 100 is defined as the Y-axis.

It can be understood that the coordinate system of electronic device 100 can be flexibly set according to specific practical needs.

[0057] Electronic device 100 may include one or more of the following: housing 10, display screen 20, camera module 30, motherboard 40, and battery 50. It should be noted that... Figure 1 , Figure 2 The accompanying drawings below only schematically illustrate some components included in the electronic device 100; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 , Figure 2 As well as the accompanying drawings below. Furthermore, since the motherboard 40 and camera module 30 are internal structures of the electronic device 100, Figure 1 The motherboard 40 and camera module 30 are schematically shown by dashed lines. In other embodiments, when the electronic device 100 is a device of some other form, the electronic device 100 may not include a display screen and a motherboard.

[0058] The housing 10 may include a frame 11 and a back cover 12. The back cover 12 is fixedly connected to one side of the frame 11. The display screen 20 is fixed to the side of the frame 11 away from the back cover 12, that is, the display screen 20 and the back cover 12 are respectively mounted on opposite sides of the frame 11. The display screen 20, the frame 11, and the back cover 12 can together enclose the interior of the electronic device 100. The interior of the electronic device 100 can be used to house components of the electronic device 100, such as a camera module 30, a motherboard 40, a receiver, a microphone, or a battery 50, etc.

[0059] The display screen 20 is used to display images, videos, etc., and can also integrate touch functionality. The display screen 20 can be a flat screen or a curved screen. The display screen 20 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a flexible light-emitting diode (FLED) display, a Miniled LED, a MicroLED, a Micro-OLED, a quantum dot light-emitting diode (QLED), or other similar displays.

[0060] In addition, the camera module 30 is located inside the electronic device 100. The camera module 30 can be used to capture ambient light from outside the electronic device 100. The camera module 30 is electrically connected to the motherboard 40. In this way, the camera module 30 and the motherboard 40 can transmit signals to each other.

[0061] In this embodiment, the camera module 30 is a rear-facing camera module. The camera module 30 can be a standard camera module, a telephoto camera module, a wide-angle camera module, an ultra-telephoto camera module, or an ultra-wide-angle camera module. The rear-facing camera module 30 is located below the rear cover 12, which has a light-transmitting hole 121. The light-transmitting hole 121 penetrates two opposite surfaces of the rear cover 12. The light-transmitting hole 121 connects the interior of the electronic device 100 to the exterior of the electronic device 100. The rear-facing camera module 30 can capture images from the rear of the electronic device 100 through the light-transmitting hole 121 to achieve image capture.

[0062] Of course, in other embodiments, the camera module 30 can also be a front-facing camera module. When the camera module 30 is a front-facing camera module, it is located below the display screen 20. The display screen 20 is provided with a light-transmitting part, and the front-facing camera module 30 collects light from in front of the electronic device 100 through the light-transmitting part to achieve shooting.

[0063] The motherboard 40 is located inside the casing 10, and integrates a processor, memory, and other various circuit devices. It also includes a display screen 20, a camera module 30, and a coupling processor. The processor may include one or more processing units, such as an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU). Different processing units may be independent devices or integrated into one or more processors.

[0064] The processor can generate operation control signals based on the instruction opcode and timing signals to control the fetching and execution of instructions.

[0065] The processor may also include internal memory for storing instructions and data. In some embodiments, the processor's memory may be a cache memory. This memory can store instructions or data that the processor has used or that are used frequently. If the processor needs to use the instruction or data, it can retrieve it directly from this memory. This avoids repeated accesses, reduces processor latency, and thus improves system efficiency.

[0066] In some embodiments, the processor may include one or more interfaces. Interfaces may include inter-integrated circuit (I2C) interfaces, inter-integrated circuit sound (I2S) interfaces, pulse code modulation (PCM) interfaces, universal asynchronous receiver / transmitter (UART) interfaces, mobile industry processor interfaces (MIPI), general-purpose input / output (GPIO) interfaces, subscriber identity module (SIM) interfaces, and / or universal serial bus (USB) interfaces, etc. The processor can connect to relevant functional modules through at least one of these interfaces.

[0067] The memory can be used to store computer executable program code, which includes instructions. The memory may include a program storage area and a data storage area. The program storage area may store the operating system, at least one application program required for a function (such as a camera function, a video recording function, etc.), etc. The data storage area may store data created during the use of the electronic device 100 (such as image data, video data, etc.). Furthermore, the memory may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc. The processor executes various functional methods or data processing of the electronic device 100 by running instructions stored in the memory and / or instructions stored in memory located within the processor, for example, causing the display screen 20 to display a target image, causing the camera module 30 to capture a target image, etc. The battery 50 is used to power the electronic device 100.

[0068] Electronic device 100 may also include one or more functional modules such as antenna modules, mobile communication modules, sensor modules, motors, microphone modules, and speaker modules. The functional modules are coupled to a processor. Antenna modules are used to transmit and receive electromagnetic wave signals. Antenna modules may include multiple antennas, each of which can cover one or more communication frequency bands. Different antennas can be reused to improve antenna utilization. Mobile communication modules can provide solutions for wireless communication applications including 2G / 3G / 4G / 5G on electronic device 100. Sensor modules may include one or more pressure sensors, gyroscope sensors, barometric pressure sensors, magnetic sensors, accelerometers, distance sensors, proximity sensors, fingerprint sensors, temperature sensors, touch sensors, or ambient light sensors. Motors can generate vibration alerts. Motors can be used for incoming call vibration alerts or for touch vibration feedback. Microphone modules are used to convert sound signals into electrical signals. Speaker modules are used to convert electrical signals into sound signals.

[0069] The following description uses camera module 30 as an example of a rear-facing camera module.

[0070] Please see Figure 2 and Figure 3 , Figure 3 yes Figure 2 A schematic diagram of the electronic device 100 in another state. Among them, Figure 2 The camera module of the electronic device shown is in a non-shooting state. Figure 3 The camera module of the electronic device shown is in shooting mode.

[0071] In this embodiment, some of the camera modules 30 can extend outside the electronic device 100 through the light-transmitting hole 121 (e.g., Figure 3 The camera module 30 can be fixedly connected to the wall of the light-transmitting hole 121. That is, the camera module 30 in this embodiment is a retractable camera module 30. The camera module 30 can be in two states: a shooting state and a non-shooting state. The shooting state can be the process from the start of shooting to the end of shooting. The non-shooting state can be the state after shooting has ended, or the state before shooting has started.

[0072] It is understandable that when the camera module 30 is not in a shooting state, such as Figure 2 The camera module 30 is housed inside the electronic device 100, and the thickness of the camera module 30 in the Z-axis direction is a first thickness. When the camera module 30 is in the shooting state, such as Figure 3The camera module 30 extends beyond its outer edge, and the thickness of the camera module 30 in the Z-axis direction is a second thickness. The first thickness is less than the second thickness. Thus, this embodiment can significantly reduce the thickness of the camera module 30 in the Z-axis direction by adding an additional state of the camera module 30 (i.e., the non-shooting state of the camera module 30), thereby achieving a thinner design for the camera module 30.

[0073] The structure of the camera module 30 will be described in detail below with reference to the accompanying drawings.

[0074] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 2 A schematic diagram of the structure of the camera module 30 of the electronic device 100 shown; Figure 5 yes Figure 4 The exploded view of the camera module 30 is shown.

[0075] The camera module 30 may include a module circuit board 31, a photosensitive chip 32, a module bracket 33, a filter 34, a lens assembly 35, an airbag 36, a mounting bracket 37, a housing 38, and a drive assembly 39. Of course, in other embodiments, the camera module 30 may not include a mounting bracket.

[0076] The photosensitive chip 32, also known as an image sensor or photosensitive element, is used to acquire optical images and convert them into electrical signals. The photosensitive chip 32 is fixed to and electrically connected to the module circuit board 31. At this time, signals can be transmitted between the photosensitive chip 32 and the module circuit board 31.

[0077] For example, the module circuit board 31 is provided with a recess 311. The photosensitive chip 32 is located in the recess 311. In this way, the camera module 30 is less likely to increase in thickness due to the photosensitive chip 32 and the module circuit board 31 stacking together.

[0078] Additionally, the module circuit board 31 may be provided with a clearance notch B to avoid other components of the camera module 30. A reinforcing plate 312 is fixed to the surface of the module circuit board 31 facing away from the photosensitive chip 32 to enhance the overall strength of the module circuit board 31.

[0079] Please see Figure 6 and Figure 7 , Figure 6 yes Figure 5 A schematic diagram of the module support 33 in the structure shown; Figure 7 yes Figure 6 The diagram shows the module support 33 from another angle. Figure 7 The module bracket 33 shown is composed of Figure 6The module bracket 33 shown is obtained by rotating it 180 degrees to the left and right.

[0080] The module bracket 33 may include a fixing hole 331, a receiving groove 332, and a light-transmitting hole 333. The module bracket 33 has a first surface 334 and a second surface 335 disposed opposite to each other. The fixing hole 331 is formed on the first surface 334, the receiving groove 332 is formed on the second surface 335, and the light-transmitting hole 333 penetrates through the first surface 334 and the second surface 335 and communicates with the receiving groove 332. The receiving groove 332 is used to receive a filter 34, which is fixed within the receiving groove 332. The fixing hole 331 is used for connection to a portion of the lens assembly structure, and the light-transmitting hole 333 allows ambient light from the lens assembly to pass through.

[0081] Please see Figure 6 , Figure 8 and Figure 9 , Figure 8 yes Figure 6 The diagram shows the structure of the module bracket 33 mounted on the module circuit board 31. Figure 9 yes Figure 8 The diagram shows a cross-sectional view of the structure along the AA direction.

[0082] The module bracket 33 is fixed to the module circuit board 31, with its second surface 335 facing the module circuit board 31. The light-transmitting hole 333 is directly opposite the photosensitive chip 32 disposed on the module circuit board 31. The filter 34 is fixed within the receiving groove 332 and positioned above the photosensitive chip 32. Exemplarily, the module bracket 33 can be fixedly connected to the module circuit board 31 by means of adhesive bonding, etc., and the filter 34 can be fixedly connected to the module bracket 33 by means of adhesive bonding, etc. Of course, in other embodiments, the module bracket can also be fixed to the module circuit board by other connection methods, and the filter can also be fixedly connected to the module bracket by other connection methods.

[0083] The filter 34 can be used to filter infrared light passing through the lens assembly and allow the filtered light to propagate to the photosensitive chip 32, thereby ensuring the electronic device 100 ( Figure 1 It has better clarity. The filter 34 can be, but is not limited to, a blue glass filter 34. For example, the filter 34 can also be a reflective infrared filter, or a double-pass filter (a double-pass filter allows visible light and infrared light in the light to pass through simultaneously, or allows visible light in the light to pass through simultaneously with other light of a specific wavelength (e.g., ultraviolet light), or allows infrared light to pass through simultaneously with other light of a specific wavelength (e.g., ultraviolet light).

[0084] Please see Figure 10 and Figure 11 , Figure 10 yes Figure 5 A schematic diagram of the structure of the lens assembly 35 shown. Figure 11 yes Figure 10 The diagram shows the structure of the lens assembly 35 mounted on the lens bracket.

[0085] The lens assembly 35 may include a first lens group assembly 351, a second lens group assembly 352, a guide post 353, and a driving member (not shown). The first lens group assembly 351 and the second lens group assembly 352 pass through the guide post 353 in sequence. The second lens group assembly 352 is disposed on the light-emitting side of the first lens group assembly 351. The driving member is used to drive the first lens group assembly 351 and the second lens group assembly 352 to move relative to the guide post 353. The guide post 353 is used to guide the first lens group assembly 351 and the second lens group assembly 352 so that the first lens group assembly 351 and the second lens group assembly 352 do not deflect during movement. Of course, in other embodiments, the lens assembly 35 may not include the driving member, and the driving component 39 of the camera module 30 may also be used to drive the first lens group assembly 351 and the second lens group assembly 352 of the lens assembly 35 to move relative to the guide post 353.

[0086] Please refer to the following: Figure 12 , Figure 12 yes Figure 11 The diagram shows a cross-sectional view of the structure along the BB direction.

[0087] The first mirror assembly 351 may include a first mirror group 511 and a first mirror group support 512. The first mirror group support 512 is a hollow structure with both ends connected, and the first mirror group 511 is fixedly connected inside the first mirror group support 512. In this embodiment, the first mirror group 511 may include two sub-mirror groups 5111, which are fixedly spaced and fixed inside the first mirror group support 512 along the optical axis of the first mirror group 511. Of course, in other embodiments, the first mirror group 511 may include only one sub-mirror group 5111, or the first mirror group 511 may include multiple sub-mirror groups 5111.

[0088] The first lens group support 512 includes a light-incident end 512a and a light-exit end 512b disposed opposite to the light-incident end 512a. A protrusion 5121 is provided on the outer side of the first lens group support 512, which is close to the light-incident end 512a. The protrusion 5121 is used to connect other structures of the camera module 30.

[0089] The first lens group bracket 512 has a fixing groove 5122 inside, and the first lens group 511 is fixedly connected to the fixing groove 5122. The first lens group 511 can be fixed to the fixing groove 5122 by applying adhesive. It can be understood that the fixing groove 5122 is also used to limit the first lens group 511, ensuring that the first lens group 511 is stably fixed to the first lens group bracket 512.

[0090] It is understood that the sub-lens group 5111 may include a lens barrel 5112 and at least one lens (not shown) fixed inside the lens barrel 5112. For example, there may be multiple lenses, with their optical axes overlapping to form a lens group, thereby achieving better optical performance. The lens barrel 5112 can be fixed to the fixing groove 5122 by adhesive bonding. Of course, in some embodiments, the lens barrel 5112 may also be integrally formed with the first lens group support 512, thereby reducing the steps of fixing the lens barrel 5112 to the first lens group support 512 and improving the assembly efficiency of the first lens group assembly 351.

[0091] The second mirror group assembly 352 may include a second mirror group (not shown) and a second mirror group support 522. The second mirror group support 522 is a hollow structure with both ends connected. The second mirror group is fixedly connected inside the first mirror group support 512. The second mirror group may include one or more sub-mirror groups (not shown). The structures of the sub-mirror groups of the second mirror group and the sub-mirror groups 5111 of the first mirror group 511 are similar and will not be described in detail.

[0092] The second lens support 522 includes an incident light end 522a and an exit light end 522b opposite to the incident light end 522a. The inner diameter of the second lens support 522 is larger than the outer diameter of the exit light end 512b of the first lens support 512. As a result, when the first lens support 512 moves toward the second lens support 522, the exit light end 512b of the first lens support 512 can partially extend into the interior of the second lens support 522. Thus, the first lens support 512 and the second lens support 522 have an overlapping portion in the Z-axis, which is beneficial for achieving a thinner camera module 30 in the Z-axis direction.

[0093] In this embodiment, a limiting block 5221 is also provided inside the second lens group support 522. The limiting block 5221 is used to prevent the first lens group support 512 from excessively extending into the second lens group support 522, thereby avoiding collision between the first lens group support 512 and the second lens group and damage to the second lens group. Of course, in other embodiments, the limiting block 5221 can also be provided on the outside of the first lens group support 512 to prevent the first lens group support 512 from excessively extending into the second lens group support 522.

[0094] like Figure 10 and Figure 11 In this embodiment, there are two guide posts 353, which are spaced apart and pass through the opposite sides of the first mirror assembly 351 and the second mirror assembly 352. By providing two guide posts 353, it is ensured that both sides of the first mirror assembly 351 and the second mirror assembly 352 are provided with guide posts 353, and the forces on both sides of the first mirror assembly 351 and the second mirror assembly 352 are balanced, so that the first mirror assembly 351 and the second mirror assembly 352 can move more smoothly.

[0095] Of course, in one embodiment of another, the lens assembly 35 includes only a first lens group assembly 351, a guide post 353, and a driving member. The first lens group assembly 351 is slidably connected to the guide post 353, and the driving member is used to drive the first lens group assembly 351 to slide along the guide post 353. That is, the lens assembly 35 does not include a second lens group assembly. In another embodiment of another, the lens assembly may also include multiple lens group assemblies.

[0096] like Figure 8 , Figure 11 and Figure 12 The module circuit board 31 is located on the light-emitting side of the lens assembly 35. Specifically, the guide post 353 is fixedly connected to the fixing hole 331 of the module bracket 33 to indirectly fix the lens assembly 35 to the module circuit board 31. Ambient light can pass through the first lens group assembly 351, the second lens group assembly 352, and the filter 34 in sequence and be sensed by the photosensitive chip 32.

[0097] Figure 12 When the camera module 30 is in a non-shooting state, both the second lens assembly 352 and the first lens assembly 351 are close to the photosensitive chip 32, reducing the thickness of the camera module 30 and allowing it to be housed inside the electronic device 100. When the camera module 30 changes from a non-shooting state to a shooting state, the first lens assembly 351 and the second lens assembly 352 can move away from the photosensitive chip 32, and part of the camera module 30 extends out of the rear cover 12 of the electronic device 100. Figure 3 It has reached the shooting state and is able to take pictures.

[0098] Of course, in other embodiments, the second lens assembly can also remain fixed. When the camera module is in a non-shooting state, the first lens assembly moves closer to the second lens assembly, reducing the thickness of the camera module and allowing it to be housed inside the electronic device. When the camera module changes from a non-shooting state to a shooting state, the first lens assembly can move away from the second lens assembly, and part of the camera module extends out of the back cover of the electronic device, achieving the shooting state and enabling it to take pictures.

[0099] Please see Figure 13 , Figure 14 and Figure 15 , Figure 13 yes Figure 5 The schematic diagram shown is of the module circuit board 31, lens assembly 35 and airbag 36 in a non-shooting state. Figure 14 yes Figure 13 The diagram shown is a schematic representation of the structure in the CC direction. Figure 15 yes Figure 13 The diagram shown is a schematic of the structure in the shooting state.

[0100] The airbag 36 includes a first end 361 and a second end 362 that are disposed opposite to each other. The airbag 36 surrounds the lens assembly 35. The first end 361 of the airbag 36 is connected to the light-incident side of the first lens group assembly 351, and the second end 362 of the airbag 36 is connected to the module circuit board 31. The airbag 36 seals the space between the first lens group assembly 351 and the module circuit board 31. It can also be understood that the airbag 36 wraps around the lens assembly 35.

[0101] Understandably, camera module 30 ( Figure 4 When switching from non-shooting to shooting mode, as the lens assembly 35 moves away from the module circuit board 31 (i.e., when the camera module rises), the airbag 36 extends (e.g., when switching from non-shooting to shooting mode). Figure 15 The gas between the airbag 36 and the lens assembly 35 enters the inner cavity of the lens assembly 35. When the camera module 30 switches from shooting mode to non-shooting mode, and the lens assembly 35 moves along the direction closer to the module circuit board 31 (i.e., when the camera module descends), the airbag 36 contracts (as shown in the image). Figure 13 The gas that enters the inner cavity of the lens assembly 35 returns to the space between the airbag 36 and the lens assembly 35, so that the air pressure inside the airbag 36 remains in a balanced state during the movement of the lens assembly 35. There is no air pressure difference resistance during the lifting and lowering of the lens assembly 35, ensuring smooth lifting and lowering of the lens assembly 35.

[0102] This application uses an airbag 36 inside the camera module 30 to seal the lens assembly 35, preventing external moisture and dust particles from entering the inner cavity of the lens assembly 35. This prevents external moisture from entering the inner cavity of the lens assembly 35 and forming water mist on the lens, and prevents external dust particles from entering the inner cavity of the lens assembly 35 and adhering to the lens, thus avoiding affecting the image quality of the camera module 30. The camera module 30 of this application has good image quality. At the same time, the airbag 36 in this embodiment completely encloses the lens assembly 35, making the camera module 30 more waterproof and dustproof.

[0103] Of course, in embodiments where the lens assembly 35 only includes the first lens group assembly 351 and the guide post 353, the airbag 36 surrounds the first lens group assembly 351 and the guide post 353. The first end 361 of the airbag 36 is connected to the light-incident side of the first lens group assembly 351, and the second end 362 is connected to the module circuit board 31. The airbag 36 seals the space between the first lens group assembly 351 and the module circuit board 31. When the first lens group assembly 351 moves away from the module circuit board 31, the airbag 36 stretches; when the first lens group assembly 351 moves towards the module circuit board 31, the airbag 36 contracts.

[0104] In other embodiments, when the lens assembly includes multiple lens groups, the airbag encloses all the lens groups of the lens assembly to prevent external moisture from entering the inner cavity of the lens assembly and forming water mist on the lenses of the multiple lenses of the lens assembly 35, or to prevent external dust particles from entering the inner cavity of the lens assembly 35 and adhering to the lenses of the multiple lens groups of the lens assembly 35, so as to avoid affecting the shooting effect of the camera module 30.

[0105] In this embodiment, the airbag 36 can be made of silicone, a material with a certain degree of flexibility and elasticity, to facilitate its stretching and contraction. Of course, the airbag 36 can also be made of other flexible and elastic materials besides silicone. When the airbag 36 contracts, it is in its natural state, and is corrugated in the direction of movement of the first lens assembly 351. It is understood that in this embodiment, by shaping the contracted (natural) airbag 36 into a regular corrugated shape, excessive deformation is prevented during contraction, avoiding the airbag 36 from deforming and protruding and getting stuck between adjacent components of the camera module 30, thus affecting the normal shooting of the camera module 30.

[0106] In this embodiment, as Figure 14 The first end 361 of the airbag 36 is fixedly connected to the protrusion 5121 of the first lens group support 512. This application provides the protrusion 5121 near the light-incident end 512a of the first lens group support 512 to facilitate the connection of the first end 361 of the airbag 36 to the first lens group support 512. Simultaneously, the protrusion 5121 increases the contact area between the first end 361 of the airbag 36 and the first lens group support 512, making the first end 361 of the airbag 36 more firmly connected to the first lens group support 512.

[0107] For example, the protrusion 5121 has an installation space 5123, which is arranged along the periphery of the protrusion 5121, and the first end 361 of the airbag 36 is fixed to the installation space 5123. In this embodiment, the installation space 5123 is an installation groove. On the one hand, the installation space 5123 can limit the first end 361 of the airbag 36, ensuring that the first end 361 of the airbag 36 is stably fixed to the protrusion 5121. On the other hand, the first end 361 of the airbag 36 and the protrusion 5121 have an overlapping part on the Z-axis, which is beneficial to achieving a thinner camera module 30. Of course, in other embodiments, the first end 361 can also be directly fixed to the surface of the protrusion 5121.

[0108] In this embodiment, the first end 361 of the airbag 36 is fixed to the installation space 5123 by in-mold injection molding, ensuring the connection strength between the airbag 36 and the first lens group support 512, and also ensuring a seamless connection between the airbag 36 and the first lens group support 512. Of course, in other embodiments, the first end 361 of the airbag 36 can also be fixedly connected to the protrusion 5121 by means of adhesive or other methods.

[0109] Please see Figure 16 and Figure 17 , Figure 16 yes Figure 5 A schematic diagram of the fixed bracket 37 in the structure shown; Figure 17 yes Figure 16 The diagram shows the structure of the fixed bracket 37 from another angle. Figure 17 The fixed bracket 37 shown is composed of Figure 16 The fixed bracket shown is obtained by rotating it 180 degrees to the left and right.

[0110] In this embodiment, the second end 362 of the airbag 36 is indirectly connected to the module circuit board 31 via a fixing bracket 37. For example, the second end 362 of the airbag 36 is bonded to the fixing bracket 37, and the fixing bracket 37 is bonded to the module circuit board 31 to ensure a seamless connection between the second end 362 of the airbag 36 and the module circuit board 31.

[0111] Of course, in another embodiment, the connection between the second end 362 of the airbag 36 and the fixed bracket 37, and the connection between the fixed bracket 37 and the module circuit board 31, may not be limited to the above description, as long as there is a seamless connection between the second end 362 of the airbag 36 and the module circuit board 31.

[0112] The fixing bracket 37 may include a holding portion 371 and a fixing portion 372, with the fixing portion 372 connected to the holding portion 371. In this embodiment, the holding portion 371 is annular, and there are three fixing portions 372, which are spaced apart and connected to the outer edge of the holding portion 371. In this embodiment, the fixing portions 372 are spaced apart and connected to the outer edge of the holding portion 371, which saves material, reduces cost, and lowers the weight of the camera module 30 compared to fixing portions 372 being connected to the entire outer edge of the holding portion 371. Of course, in other embodiments, the shape of the holding portion 371 can be other shapes, and the number of fixing portions 372 can be one, two, or more than three.

[0113] Please refer to the following: Figure 13 and Figure 14The fixing part 372 is fixed to the module circuit board 31, and the pressing part 371 is connected to the side of the second end 362 of the airbag 36 facing away from the module circuit board 31. In other words, this embodiment uses the fixing bracket 37 to connect the second end 362 of the airbag 36 to the module circuit board 31, which is more convenient than directly connecting the second end 362 of the airbag 36 to the module circuit board 31 and effectively improves product assembly efficiency. At the same time, the second end 362 of the airbag 36 is essentially clamped between the fixing bracket 37 and the module circuit board 31, allowing for a more stable fixation to the module circuit board 31 compared to adhesive bonding.

[0114] In addition, the fixing bracket 37 can effectively prevent the second end 362 of the airbag 36 from being stretched during the extension and retraction process. It is understandable that when the camera module 30 switches from a non-shooting state to a shooting state, the airbag 36 is stretched, and the second end 362 of the airbag 36 will be subjected to a pulling force towards the first end 361. After repeated stretching, this can affect the adhesive strength between the second end 362 and the module circuit board 31. This application addresses this by providing the fixing bracket 37, so that the pressing part 371 of the fixing bracket 37 presses the second end 362 against the module circuit board 31, preventing the tensile force from each stretching of the airbag 36 from being transmitted to the second end 362, ensuring the adhesive strength between the second end 362 and the module circuit board 31, and extending the lifespan of the airbag 36.

[0115] It is understood that this embodiment does not limit the specific shape of the fixing bracket 37, as long as it can press the second end 362 onto the module circuit board 31.

[0116] In this embodiment, as Figure 14 and Figure 17 The holding portion 371 may include a pressing groove 3711, and the second end 362 is fixed within the pressing groove 3711. It is understood that the pressing portion 371, by providing the pressing groove 3711, avoids directly pressing the pressing portion 371 against the second end 362 of the airbag 36, as the pressing force would damage the second end 362. The pressing groove 3711 accommodates and fixes the second end 362, preventing damage to the second end 362 of the airbag 36. Of course, in other embodiments, the pressing portion may not include a pressing groove, and the pressing portion may directly press against the second end of the airbag.

[0117] like Figure 18 , Figure 18 yes Figure 14 The diagram shows a partial structural schematic of the structure shown. In this embodiment, the surface where the pressing part 371 contacts the second end 362 of the airbag 36 is the contact surface 3712. The contact surface 3712 is an arc surface to avoid scratching the second end 362 when the pressing part 371 contacts the second end 362, thus extending the life of the airbag 36. Of course, in other embodiments, the contact surface 3712 may not be an arc surface.

[0118] In another implementation scenario of other embodiments, the second end 362 of the airbag 36 can also be directly connected to the module circuit board 31, for example, by adhesive bonding, such as by applying glue, to ensure a seamless connection between the second end 362 of the airbag 36 and the module circuit board 31. Alternatively, the second end 362 of the airbag 36 can also be fixedly connected to the module circuit board 31 by other connection methods besides adhesive bonding, as long as a seamless connection between the second end 362 of the airbag 36 and the module circuit board 31 is ensured.

[0119] It is understandable that in embodiments where the second end 362 of the airbag 36 is directly bonded to the module circuit board 31, the camera module may also include a fixing bracket 37. The difference is that the fixing part 372 can be fixed to the module circuit board 31, and the pressing part 371 is located on the side of the second end 362 of the airbag 36 facing away from the module circuit board 31 to prevent the second end of the airbag from being pulled. It is understandable that when the camera module switches from a non-shooting state to a shooting state, the airbag is stretched, and the second end of the airbag will be subjected to a pulling force towards the first end. After multiple stretching cycles, the adhesion between the second end and the module circuit board may be affected. This application addresses this by providing a fixing bracket, so that the pressing part of the fixing bracket presses the second end against the module circuit board, preventing the tensile force from each stretching of the airbag from being transmitted to the second end, ensuring the adhesion between the second end and the module circuit board, and extending the lifespan of the airbag.

[0120] In some implementation scenarios, the pressure-holding part may include a pressure groove, with the second end confined within the pressure groove. It is understood that the pressure-holding part, by providing a pressure groove, prevents the pressure-holding part from directly pressing against the second end of the airbag, as the pressing force would damage the second end. The pressure groove merely confines the second end without causing damage. Of course, in other embodiments, the pressure-holding part may not include a pressure groove, and the pressure-holding part may directly press against the second end of the airbag.

[0121] Please see Figure 5 , Figure 19 and Figure 20 , Figure 19 yes Figure 5 An exploded view of the shell 38 of the structure shown; Figure 20 yes Figure 4 The diagram shows the structure of the housing 38 in the DD direction.

[0122] The housing 38 may include an inner cylinder 381, an outer cylinder 382, ​​and a light-transmitting plate 383. In this embodiment, both the inner cylinder 381 and the outer cylinder 382 are hollow structures with openings at both ends. The outer cylinder 382 is sleeved outside the inner cylinder 381 and is movable relative to the inner cylinder 381. The light-transmitting plate 383 is fixedly connected to the outer cylinder 382 and covers one opening of the outer cylinder 382.

[0123] In this embodiment, the outer cylinder 382 is slidably connected to the inner cylinder 381. For example, the inner cylinder 381 may include a cylinder body 3811, a first mounting block 3812, and a second mounting block 3813. The first mounting block 3812 and the second mounting block 3813 are connected to opposite ends of the cylinder body 3811. A sliding rod 3814 is fixed between the first mounting block 3812 and the second mounting block 3813. A mating part 3821 is provided on the side of the inner wall of the outer cylinder 382 away from the light-transmitting plate 383. The mating part 3821 may include a through hole 3822, and the sliding rod 3814 passes through the through hole 3822 of the mating part 3821, so that the outer cylinder 382 moves along the direction in which the sliding rod 3814 extends. It is understood that the outer cylinder 382 moves relative to the inner cylinder 381 along the sliding rod 3814, and the sliding rod 3814 serves to guide the outer cylinder 382, ​​preventing the outer cylinder 382 from deflecting during movement.

[0124] In this embodiment, there are three first mounting blocks 3812, which are arranged along the outer edge of one end of the cylinder 3811. There is one second mounting block 3813, which is arranged along the outer edge of the other end of the cylinder 3811. Each second mounting block 3813 has three mounting holes 3815, which are respectively corresponding to the three first mounting blocks 3812. There are three sliding rods 3814, which are installed between the corresponding first mounting blocks 3812 and the mounting holes 3815. Of course, in other embodiments, the number of first mounting blocks 3812, the number of mounting holes 3815, and the number of sliding rods 3814 may not be limited to the above description and can be set as needed.

[0125] The inner cylinder 381 may also include a third mounting block 3816, and the second mounting block 3813 is also provided with a fixing hole 3817. The third mounting block 3816 is arranged opposite to the fixing hole 3817 for a portion of the components of the drive assembly 39.

[0126] In this embodiment, the cylindrical body 3811 is provided with a notch A near the second mounting block 3813 to avoid other components of the camera module 30.

[0127] Please see Figure 21 , Figure 21 yes Figure 19 A schematic diagram of the outer cylinder 382 of the structure shown from another angle.

[0128] The inner wall of the outer cylinder 382 is further provided with a first receiving portion 5 and a second receiving portion 6 spaced apart. The first receiving portion 5 may include a top wall 51 and a peripheral wall 52, which together form a first receiving hole 53. The peripheral wall 52 has a first opening 54 that communicates with the first receiving hole 53. The second receiving portion 6 may include a top wall 61 and a peripheral wall 62, which together form a second receiving hole 63. The peripheral wall 62 has a second opening 64 that communicates with the second receiving hole 63. The second opening 64 is disposed opposite to the first opening 54. The first receiving portion 5 and the second receiving portion 6 are used to cooperate with the drive assembly 39 to realize the movement of the outer cylinder 382 relative to the inner cylinder 381.

[0129] like Figure 3 , Figure 22 and Figure 23 , Figure 22 yes Figure 4 A schematic diagram of the cross-sectional structure of the camera module 30 in the EE direction;

[0130] Figure 23 yes Figure 19 A schematic diagram of the inner cylinder 381 in the structure shown from another angle.

[0131] The housing 38 is fixed to the module circuit board 31 and sleeved around the outer periphery of the airbag 36. Specifically, the inner cylinder 381 is fixed to the module circuit board 31 and disposed around the outer periphery of the airbag 36. In this embodiment, the second mounting block 3813 of the inner cylinder 381 is fixed to the module circuit board 31. The inner cylinder 381 may include a positioning groove 3818, which is formed on the surface of the second mounting block 3813 facing away from the first mounting block 3812. When the inner cylinder 381 is fixed to the module circuit board 31, a portion of the structure of the fixing bracket 37 (fixing part 372) is received within the positioning groove 3818.

[0132] It is understandable that the positioning groove 3818 of the inner cylinder 381 and the fixing part 372 of the fixing bracket 37 can form a limiting relationship, so that the inner cylinder 381 of the housing 38 can be quickly installed on the module circuit board 31. At the same time, the fixing bracket 37 and the inner cylinder 381 have an overlapping part in the Z-axis, which is beneficial to the thinning of the camera module 30.

[0133] In this embodiment, the number of positioning grooves 3818 corresponds to the number of fixing parts 372, and the fixing parts 372 are disposed in the corresponding positioning grooves 3818. Of course, in other embodiments, the inner cylinder may not include positioning grooves.

[0134] In this embodiment, the inner cylinder 381 of the housing 38 is sleeved around the outer periphery of the airbag 36 and fixed to the module circuit board 31. That is, the airbag 36 is located inside the space enclosed by the housing 38 and the module circuit board 31. Compared with placing the airbag 36 between the housing 38 and the module circuit board 31, the airbag 36 will not protrude outward from the housing 38 when it is extended or retracted. Instead, it is contained in the space between the housing 38 and the module circuit board 31. This is beneficial to protect the airbag 36, prevent the airbag 36 from being exposed to the outside of the camera module 30 and causing friction with other devices, avoid friction damage to the airbag 36, and extend the service life of the airbag 36.

[0135] Please see Figure 22 and Figure 24 , Figure 24 yes Figure 3 Another exploded structural diagram of the structure shown.

[0136] The drive assembly 39 drives the outer cylinder 382, ​​causing it to move relative to the inner cylinder 381 in the direction in which the first lens assembly 351 moves. It is understood that when the camera module 30 switches from a non-shooting state to a shooting state, the lens assembly 35 moves away from the module circuit board 31, and simultaneously, the drive assembly 39 also drives the outer cylinder 382 to move away from the module circuit board 31, preventing the housing 38 from interfering with the movement of the lens assembly 35. The camera module 30 partially extends out of the electronic device 100. When the camera module 30 switches from a shooting state to a non-shooting state, the lens assembly 35 moves closer to the camera module 30, and simultaneously, the drive assembly 39 also drives the outer cylinder 382 to move closer to the module circuit board 31. The camera module 30 is then housed inside the electronic device 100.

[0137] like Figure 24 and Figure 25 , Figure 25 yes Figure 4 The diagram shows a cross-sectional view of the camera module 30 in the FF direction.

[0138] The drive assembly 39 may include a drive unit 391, a screw 392, and a slider 393. The screw 392 is fixed to the outside of the inner cylinder 381. For example, the screw 392 is connected between the third mounting block 3816 and the fixing hole 3817. The slider 393 includes a first part 3931 and a second part 3932. The first part 3931 is rotatably connected to the screw 392, and the second part 3932 is connected to the outer cylinder 382. The drive unit 391 is partially located within the clearance notch B of the module circuit board 31 and is rotatably connected to the screw 392. The drive unit 391 is electrically connected to the module circuit board 31, and the module circuit board 31 controls the drive unit 391 to drive the screw 392 to rotate, thereby controlling the movement of the outer cylinder 382 relative to the inner cylinder 381 in the direction of movement of the first mirror assembly 351.

[0139] In some embodiments, the drive assembly 39 may further include a spring 394, which is elastically connected between the second portion 3932 and the outer cylinder 382. For example, there are two second portions 3932 connected to opposite sides of the first portion 3931, which is located between the first receiving portion 5 and the second receiving portion 6. One second portion 3932 extends into the first receiving hole 53 through the first opening 54, and the other second portion 3932 extends into the second receiving hole 63 through the second opening 64. There are also two springs 394: one spring 394 is received in the first receiving hole 53 and its two ends are fixedly connected to the bottom wall of the first receiving hole 53 and the corresponding second portion 3932, respectively; the other spring 394 is received in the second receiving hole 63 and its two ends are fixedly connected to the bottom wall of the second receiving hole 63 and the corresponding second portion 3932, respectively.

[0140] like Figure 25 and Figure 26 , Figure 26 yes Figure 25 The diagram shows the structure of the camera module 30 in another state.

[0141] When the camera module 30 switches from a non-shooting state to a shooting state, the drive unit 391 drives the screw 392 to rotate in the first direction, and the slider 393 moves away from the fixing hole 3817. The second part 3932 of the slider 393 compresses the spring 394 to push the outer cylinder 382 upward, so that the camera module 30 is in the shooting state (e.g., ...). Figure 26 When the camera module 30 switches from the shooting state to the non-shooting state, the drive unit 391 drives the screw 392 to rotate in the second direction, wherein the first direction and the second direction are opposite. The slider 393 moves towards the direction closer to the fixing hole 3817, and the spring 394 pulls the outer cylinder 382 down, so that the camera module 30 is in the non-shooting state (e.g., ...). Figure 25 ).

[0142] In this embodiment, a spring 394 is provided between the second part 3932 and the outer cylinder 382. The outer cylinder 382 is indirectly pushed or pulled by the spring 394 to rise or fall. Compared with the second part 3932 being directly connected to the outer cylinder 382, ​​the outer cylinder 382 moves more smoothly during the rising or falling process.

[0143] Meanwhile, by setting a second part 3932 on both sides of the first part 3931, the force balance on both sides of the first part 3931 is ensured. Thus, the slider 393 will not be stuck on the screw 392 due to the different forces on both sides during the movement, and the slider 393 can move more smoothly.

[0144] Of course, in other embodiments, the slider 393 may also include only the first part 3931, with the middle part of the slider 393 rotatably connected to the screw 392, and the outer cylinder 382 fixedly connected to the side near the outer cylinder 382.

[0145] In this embodiment, as Figure 26 The camera module 30 may also include cover plates 70. Specifically, there are two cover plates 70. One cover plate 70 is fixedly connected to the opening of the first receiving hole 53 to confine the second part 3932 within the first receiving hole 53, so that the second part 3932 will not disengage from the first receiving hole 53 due to the elastic force of the spring 394. One cover plate 70 is fixedly connected to the opening of the second receiving hole 63 to confine the other second part 3932 within the second receiving hole 63, so that the other second part 3932 will not disengage from the second receiving hole 63 due to the elastic force of the spring 394. In other words, both cover plates 70 ensure a stable pushing relationship between the outer cylinder 382 and the slider 393.

[0146] Please refer to it again. Figure 22 The drive unit 391 may include a motor 3911 and a reduction gear 3912. The motor 3911 drives the reduction gear 3912 to rotate, and the reduction gear 3912 is rotatably connected to the screw 392 to drive the screw 392 to move. Of course, in other embodiments, the drive unit 391 may be other drive components, not limited to those described above. Alternatively, the drive unit 391 in this embodiment may also be used to drive the lens assembly 35 to retract.
