This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office on June 18, 2021, with application number 202110689584.8 and titled "Sealing Structure, Camera Module, and Electronic Equipment", the entire contents of which are incorporated herein by reference In this application.

technical field

The present application relates to the structure of a camera module, in particular to a sealing structure, a camera module and electronic equipment.

Background technique

Since the terminal is equipped with a camera, major manufacturers have been committed to optimizing and upgrading the terminal's camera function, and even the terminal's camera function has gradually changed from an auxiliary function to a terminal's main function.

However, as the terminal camera becomes more powerful in terms of optical functions, the size of the camera module also becomes larger. For example, the higher the pixel requirements for the image captured by the terminal, the more lenses the corresponding terminal camera needs, and the corresponding terminal camera module will also become prominent. In order to avoid the outstanding camera module from affecting the appearance and refinement of the terminal. Major manufacturers will design the camera module as a pop-up structure. In this way, the camera will only pop out when it is in use, and it will be in a retracted state when it is not in use, so that the protrusion will not affect the appearance of the terminal.

However, the camera module with pop-up structure often faces the problem of difficult sealing, and cannot be effectively waterproof and dustproof.

Contents of the invention

In view of this, the present application provides a camera module, which is sealed and connected between the camera module base and the movable structure of the camera module through a sleeve-type waterproof rubber part, so that the movable structure of the camera module When the structure moves relative to the base of the shooting module to drive the lens to move, the waterproof and dustproof of the shooting module is realized.

In the first aspect, the embodiment of the present application provides a sealing structure. The sealing structure includes a sleeve-type seal. The outer member is sealed and combined, and the inner member is sleeved on the outer member. When the relative displacement between the inner member and the outer member reaches the maximum, the sleeve type seal is in a natural state of not generating traction on the inner member and the outer member.

Due to the structural characteristics of the sleeve type seal itself, that is, the sleeve type seal is a sleeve structure, when one end of the sleeve type seal is sealed with the inner member, and the periphery of the other end of the sleeve type seal is sealed with the outer member After the combination, the sleeve seal can realize the sealing between the inner member and the outer member only by virtue of its own structural characteristics, without any resistance between the inner member and the outer member that hinders the relative movement of the inner member and the outer member An example is frictional resistance.

At the same time, when the relative displacement between the inner member and the outer member reaches the maximum, the sleeve type seal is fully stretched, and is in a natural state without any traction force on the inner member and the outer member.

For example, taking a camera module with a sleeve-type seal as an example, the drivable structure of the camera module is used as the inner member, and the base of the camera module is used as the outer member. When the relative displacement between the inner member and the outer member reaches the maximum value, the relative displacement between the drivable structure and the base reaches the maximum value, that is, the drivable structure is in the protruding state, the shooting module is in the working state, and the telescopic The seal is in its natural state.

And, further, in order to ensure that the two ports of the sleeve seal can be tightly combined with the inner member and the outer member respectively, in some embodiments of the present application, the caliber of the port where the sleeve seal is sealed with the inner member It is smaller than the caliber of the other port where the sleeve seal is sealingly combined with the outer member.

In order to reduce the length of time that the sleeve seal is in a redundant state, in a possible implementation of the first aspect, when the relative displacement between the inner member and the outer member is 0, the sleeve seal is also in the non-aligned inner member The natural state of generating traction with the external member.

For example, continue to take the shooting module with a sleeve-type seal as an example, the movable structure of the shooting module is used as the internal component, and the base of the shooting module is used as the external component. When the relative displacement between the internal component and the external component is 0, That is to say, the relative displacement between the movable structure of the shooting module and the base of the shooting module is 0, and the movable structure is in a contracted state. At this time, the sleeve-type seal is also in a position that does not generate traction on the movable structure and the base. natural state.

In combination with the above-mentioned embodiments, it can be seen that no matter whether the relative displacement between the inner member and the outer member is the maximum value or 0, that is, no matter whether the shooting module is in the working state or in the shrinking state, the sleeve seal is in a natural state, so The time that the sleeve type seal is in a redundant state can be reduced, so that the sleeve type seal is not easy to form creases, the aging speed of the sleeve type seal is slowed down, and the service life of the sleeve type seal is prolonged.

In a possible implementation manner of the first aspect, during the relative movement of the inner member and the outer member, the sleeve type seal is in a redundant state.

In order to enable the sleeve-type seal to better deform with the relative movement of the inner member and the outer member, in a possible implementation of the first aspect, the sleeve-type seal is made of a flexible material, such as a sleeve The cartridge seal may be a watertight rubber.

In the second aspect, an embodiment of the present application provides a camera module, the camera module includes a lens, a movable structure, a fixed structure, and a sealing structure in any possible implementation of the first aspect, and the movable structure serves as The internal component, the fixed structure is used as the external component, and the lens is set on the movable structure. When the movable structure drives the lens to pop up to the pop-up position, the relative displacement between the movable structure and the fixed structure reaches the maximum, and the sleeve seal is in the wrong position. The natural state of traction produced by structures and fixed structures.

In some embodiments of the present application, the fixing structure may be the base of the camera module.

In some other embodiments of the present application, the movable structure can be divided into a moving part and a guiding part, wherein a guiding chute is provided on the moving part, and the moving part is slidably connected to the guiding part through the guiding chute, and the movable structure is slidably connected to the guiding part through the guiding chute. The part is fixed on the base, and the lens is installed on the moving part, so that when the moving part slides relative to the guide part, the lens can be driven to move.

In a possible implementation of the second aspect, when the movable structure drives the lens to shrink to the retracted position, the relative displacement between the movable structure and the fixed structure is 0, and the sleeve seal is also in the wrong position between the movable structure and the fixed structure The natural state that produces traction.

In the third aspect, the embodiment of the present application provides an electronic device, the electronic device includes the camera module described in the second aspect and its possible implementation manners and the middle frame of the terminal, the camera module is fixed in the middle frame of the terminal, and the lens It is set on the movable structure. When shooting with the shooting module, the movable structure drives the lens to pop up to the pop-up position outside the middle frame of the terminal to complete the focusing of the shooting module. When shooting without the shooting module, the movable structure Drive the lens to shrink to the retracted position inside the middle frame of the terminal, so that the lens will not protrude outside the middle frame of the terminal.

Wherein, the pop-up position refers to the position where the movable structure is located when the camera module can finish focusing. At this time, the movable structure drives the lens to protrude from the middle frame of the terminal, so that the surface of the camera module facing away from the terminal display is higher than the surface of the terminal middle frame facing away from the terminal display; the retracted position means that the user does not use the camera module , the position of the movable structure. At this time, the movable structure drives the lens to shrink to the inside of the terminal middle frame, so that the surface of the camera module facing away from the terminal display screen can be lower than the surface of the terminal middle frame facing away from the terminal display screen, or the same as the surface of the terminal middle frame facing away from the terminal display screen. The surface is flush.

When the user does not use the camera module, the movable structure can drive the lens to completely shrink into the middle frame of the terminal without affecting the overall appearance of the electronic device; when the user uses the camera module, the movable structure can drive the lens to pop out of the terminal The middle frame, and make the camera module focus. In this way, the exposure time of the shooting module is reduced, thereby reducing the wear and tear of the shooting module, and prolonging the service life of the shooting module.

detailed description

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manner of the present application will be described in detail below in conjunction with the accompanying drawings.

The present application provides an electronic device including a pop-up camera module, and the electronic device includes a camera module and a terminal middle frame. Wherein, the camera module includes a base and a movable structure, the base is installed in the middle frame of the terminal, and the movable structure can move relative to the base. When focusing, the movable structure in the shooting module drives the lens to move relative to the photosensitive component on the base to complete focusing, and part of the structure of the shooting module pops out of the terminal middle frame after focusing. When resetting, the movable structure in the camera module drives the lens to move in reverse to complete the reset, and the camera module shrinks to the middle frame of the terminal after the reset is completed.

Since the electronic device requires the camera module to be able to pop up or shrink into the middle frame of the terminal, and the movable structure inside the camera module and the base can move with each other, there is a problem of insufficient sealing between the movable structure and the base. Insufficient sealing between the movable structure and the base will cause water vapor to penetrate into the interior of the shooting module through the gap between the shooting module and the middle frame of the terminal and between the movable structure and the base, thereby causing water vapor in the shooting module. The circuit board is rusted or short-circuited, which eventually causes the camera module to fail and cannot be used, shortening the service life of the camera module. In addition, water vapor will also cause fogging inside the camera module, affecting the shooting effect of the camera module.

In order to prevent external water vapor and dust from entering the interior of the camera module, thereby avoiding the adverse effects of external water vapor and dust on the components in the camera module, ensuring the normal use of the camera module, and prolonging the service life of the camera module, this application provides A camera module with a sealed structure.

Specifically, the shooting module includes a lens, a movable structure, a base and a sleeve-type seal. Wherein, the base is installed in the middle frame of the terminal and connected with the optical photosensitive component, and the movable structure is connected with the lens. The movable structure includes a moving part and a guiding part, the movable structure is fixed to the base through the guiding part of the movable structure, and the moving part of the movable structure moves relative to the base. The sleeve type seal is a cylindrical structure, the periphery of one port of the cylindrical structure is installed on the moving part of the movable structure, the periphery of the other port of the cylindrical structure is installed on the base, and the movable structure is opposite to the base During the moving process, the sleeve seal is in a redundant state, and when the relative displacement between the movable structure and the base reaches the maximum, the sleeve seal is in a natural state. Among them, the natural state refers to the state that the sleeve seal is in the state of not generating external traction. In the redundant state, the distance between one port and the other port of the sleeve seal is smaller than that of the next port to the other port in the natural state. port distance.

In the above-mentioned shooting module, one port of the sleeve-type seal is connected to the movable structure, and the other port is fixed on the base, so that when the movable structure moves relative to the base, the sleeve-type seal and the A port to which the movable structure is connected is capable of moving following the movement of the movable structure, while a port to which the sleeve seal is connected to the base remains fixed. In this way, in the process of moving the movable structure relative to the base, the sleeve seal seals between the movable structure and the base through its own structural characteristics; at the same time, when the movable structure and the base are relatively stationary In this state, the sleeve seal realizes the connection between the movable structure and the base through one port connected to the movable structure, the other port fixed to the base and the structural characteristics of the sleeve seal itself. between the seals.

Secondly, as mentioned above, when the relative displacement between the movable structure and the base is the largest, the sleeve type seal is in a natural state that does not generate traction force on the movable structure or the base, and when the movable structure relative to the base During movement, the sleeve seal is redundant. In the above two states, there is no frictional resistance between the sleeve seal and the base or the movable structure, that is, the movable structure does not need to overcome the frictional resistance during the movement process, therefore, the above-mentioned sealing structure reduces the The driving force of the movable structure can further reduce the volume of the driving device that provides the driving force for the movable structure, making the internal structure design of the electronic device more reasonable, saving the space inside the electronic device, and making the overall structure of the electronic device more compact. for compact.

It should be understood that the electronic device to which the technical solution of the present application is applicable may be any device with a camera module, for example, the electronic device may be a smart phone, a tablet computer, a laptop computer, a wearable device, a head-mounted display, Video equipment, folding mobile phones, smart large screens, etc., this application does not impose any restrictions on the specific form of electronic equipment.

The specific structures of the camera module, electronic equipment and sleeve-type seals in this application will be described in detail below in conjunction with the accompanying drawings.

In order to clearly show how to prevent water vapor from entering the camera module in electronic equipment through sleeve seals, before introducing the camera module with sleeve seals, a brief introduction is made between the camera module in electronic equipment and the middle frame of the terminal. The relative position and connection mode.

FIG. 1A shows a perspective view of the electronic device 1 , where the camera module 10 is in a retracted state. FIG. 1B shows a perspective view of the electronic device 1 , where the camera module 10 is in an extended state.

As shown in FIG. 1A , when the user does not need to take pictures, the camera module 10 shrinks to a retracted position (not shown) inside the terminal middle frame 20 . The photographing module 10 should be able to completely shrink into the interior of the terminal middle frame 20 to complete the reset of the photographing module 10 so that the photographing module 10 does not protrude from the terminal middle frame 20, thereby reducing the contact time between the photographing module 10 and the outside world, thereby reducing The wear and tear of the camera module 10 is taken. Moreover, the shooting surface 600 of the camera module 10 in the contracted state is flush with the middle frame surface 800 of the terminal middle frame 20, which improves the overall aesthetics of the electronic device 1. Wherein, the shooting surface 600 is a side of the shooting module 10 facing away from the display screen of the electronic device 1 (see FIG. 1A ), and the middle frame surface 800 is a side of the terminal middle frame 20 facing away from the display screen of the electronic device 1 (see FIG. Figure 1A).

In some embodiments of the present application, the shooting surface 600 of the shooting module 10 is lower than the middle frame surface 800 of the terminal middle frame 20, so that the shooting module 10 does not protrude from the middle frame surface 800 of the terminal middle frame 20, reducing The time for the camera module 10 to be in contact with the outside world can further reduce wear and tear of the camera module 10 to prolong the service life of the camera module 10 .

As shown in FIG. 1B , when the user takes a picture, the camera module 10 pops up to a pop-up position (not shown) outside the middle frame 20 of the terminal. At this time, the shooting surface 600 of the shooting module 10 protrudes from the middle frame surface 800 of the terminal middle frame 20 , and the focusing of the shooting module 10 is completed, and then the shooting demand of the user is realized through the shooting module 10 . Specifically, the photographing surface 600 of the photographing module 10 protrudes from the surface 800 of the middle frame of the terminal middle frame 20 by a predetermined distance, so as to complete the focusing of the photographing module 10 .

In some embodiments of the present application, the preset distance is related to the focal length of the camera module 10. When the focal length of the camera module 10 is larger, the preset distance is also larger, that is, the camera surface 600 of the camera module 10 protrudes The position of the middle frame surface 800 of the terminal middle frame 20 is higher; when the focal length of the shooting module 10 is smaller, the preset distance is also smaller, that is, the shooting surface 600 of the shooting module 10 protrudes from the middle frame of the terminal middle frame 20 The lower the surface 800 is. It can be understood that the driving force required for the ejection or contraction of the lens of the camera module 10 driven by the movable structure 300 is provided by a driving device (not shown).

In some embodiments of the present application, the driving end of the driving device is connected to the movable structure 300 , and the fixed end of the driving device is connected to the terminal middle frame 20 . For example, the driving device is a voice coil motor (voice coil motor, VCM), and the voice coil motor includes a carrier and a substrate, wherein the carrier is connected to the movable structure 300, and the substrate is fixedly connected to the terminal middle frame 20 with adhesive backing.

On the basis of the relative position and connection mode of the camera module in the working state and contracted state described above, the waterproof rubber part 200 as the sleeve type seal is taken as an example below, and the details are shown in Figure 2A and Figure 2B Introduce the specific structure of the camera module in this application.

Fig. 2A is a sectional view of the electronic device 1 provided by some embodiments of the present application along the section A-A in Fig. 1A, in which the camera module 10 is shrunk into the middle frame 20 of the terminal; Fig. 2B is the electronic device provided by some embodiments of the present application 1 A cross-sectional view along the section B-B in FIG. 1B , where the camera module 10 pops out of the middle frame 20 of the terminal.

As shown in Figure 2A, the present application provides a camera module 10, which includes a first connection part 100, a waterproof rubber part 200, a movable structure 300, a base 400, a circuit board 500 and an optical sensing component 510, wherein the movable structure 300 includes a moving part 310 and a guide part 320, the moving part 310 of the movable structure 300 is provided with a chute, the chute of the moving part 310 can accommodate the guide part 320, and the moving part 310 passes through the chute and The guide part 320 is movably connected. The waterproof rubber part 200 includes a port 210 and another port 220 .

Wherein, one port 210 of the waterproof rubber part 200 is sealed and combined with the moving part 310 of the movable structure 300, and the other port 220 of the waterproof rubber part 200 is sealed and combined with the base 400, and the guide part 320 of the movable structure 300 is fixed on the base 400 , the optical sensor component 510 is installed on the circuit board 500 , and the circuit board 500 is fixed on the base 400 . The camera lens (not shown) of the camera module 10 is mounted on the movable part 310 of the movable structure 300. When the camera module 10 works, the light passes through the lens and reaches the optical sensing part 510 to realize the camera function of the camera module 10 .

In some embodiments of the present application, the circuit board 500 may be a flexible printed circuit (FPC) or a printed circuit board (Process Control Block, PCB).

In the embodiment shown in FIG. 2A, when the user does not use the camera module 10, the camera module 10 is in a contracted state, that is, the camera surface 600 of the camera module 10 is flush with the middle frame surface 800 of the terminal middle frame 200 , that is, the moving part 310 of the movable structure 300 is at a retracted position inside the terminal middle frame 20 .

At this time, the displacement of the moving part 310 of the movable structure 300 relative to the base 400 is 0, the position of one port 210 of the waterproof rubber part 200 is lower than the position of the other port 220 of the waterproof rubber part 200, and the waterproof rubber part 200 passes through a The port 210 and the further port 220 achieve a seal between the moving part 310 of the movable structure 300 and the base 400 .

In the embodiment shown in FIG. 2B, when the user uses the camera module 10, the camera module 10 is in a working state, that is, the camera surface 600 of the camera module 10 protrudes from the middle frame surface 800 of the terminal middle frame 200 by default. distance, that is, the moving part 310 of the movable structure 300 can pop up to the pop-up position outside the terminal middle frame 20 .

At this time, the relative displacement between the moving part 310 of the movable structure 300 and the base 400 is the largest, and the position of one port 210 of the waterproof rubber part 200 is higher than the position of the other port 220 of the waterproof rubber part 200, and the waterproof rubber part 200 achieves sealing between the moving part 310 of the movable structure 300 and the base 400 through a port 210 and another port 220 .

It can be understood that during the ejection process of the moving part 310 of the movable structure 300 relative to the base 400, a port 210 connected between the waterproof rubber part 200 and the moving part 310 of the movable structure 300 moves along with the movement of the moving part 310, and the waterproof rubber The other port 220 connecting the part 200 to the base 400 is fixed on the base 400. During this process, the waterproof rubber part 200 is still connected to the movable part 310 and the other port 220 of the movable structure 300 Seal between bases 400 .

FIG. 3A and FIG. 3B respectively show the sealing methods of the camera module 10 in other solutions. In the shooting module 10 shown in Figure 3A, the lens is set on the movable structure 300, and the position of the terminal middle frame 20 is set with a bimodal liquid silicone rubber 200', and when the movable structure 300 drives the lens to pop up or shrink The side of the bimodal liquid silicone gel 200' close to the movable structure 300 is pressed against the side of the movable structure 300 close to the bimodal liquid silicone gel 200', and then the camera module 10 is realized in this close contact. Sealing; or, as shown in FIG. 3B , the O-ring 200 ″ is clamped on the movable structure 300, so that when the movable structure 300 drives the lens out or contracts, the O-ring 200 ″ is close to the terminal middle frame One side of 20 is in close contact with the side of the terminal middle frame 20 close to the O-ring 200 ″, and then the camera module is also sealed in this close contact manner.

It can be seen that whether the above-mentioned two kinds of annular seals are arranged on the terminal middle frame 20 and closely abut against the movable structure 300 , or are arranged on the movable structure 300 and closely abut against the terminal middle frame 20 , they will During the process that the movable structure 300 drives the lens to pop up or shrink, a frictional resistance that hinders the movement of the movable structure 300 is generated between the movable structure 300 and the terminal middle frame 20. This frictional resistance will not only accelerate the damage of the above-mentioned seals, Moreover, in order to overcome the impact of this frictional resistance on the movement of the movable structure 300, the electronic device 1 needs a driving device capable of generating a greater driving force to drive the movable structure 300 to move, and high-standard driving devices are often bulky , will occupy the internal space of the originally narrow electronic device 1 .

Compared with the above two solutions, this application fixes the two

port peripheries

220 and 210 of the sleeve-type waterproof rubber part 200 on the base 400 and the moving part 310 of the movable structure 300 respectively, wherein, with the movable The fixed port 210 of the moving part 310 of the structure 300 follows the movement of the moving part 310 when the moving part 310 of the movable structure 300 drives the lens to pop up or shrink, while the other end 220 fixed to the base 400 is in the movable structure 300 Keep the lens fixed during ejection or retraction.

In this way, when the movable structure 300 drives the lens to pop up to the pop-up position, the waterproof rubber part 200 only needs to rely on its own structural characteristics to stretch to a natural state with the movement of the movable structure 300 , thereby realizing the sealing of the camera module 10 .

Moreover, during the movement of the movable structure 300 relative to the base 400 , the waterproof rubber part 200 is in a redundant state, and no frictional resistance hindering the movement of the movable structure 300 will be generated.

Through the aforementioned method, not only the loss of the waterproof rubber part 200 itself is reduced, the service life of the waterproof rubber part 200 is improved, but also the driving force for the movement of the movable structure 300 is reduced, and the power consumption of the camera module 10 is reduced. The reduction of the driving force for the movement of the mobile structure 300 also reduces the volume of the driving device that provides the driving force, further reducing the space occupied by the driving device, saving the internal space of the terminal middle frame 200 of the electronic device 1, and optimizing the electronic device 1. Spatial arrangement of other functional components.

Further, for the same electronic device 1, the distance between the pop-up position of the camera module 10 in the working state and the retracted position in the contracted state is fixed, that is, the user uses the camera module 10 When shooting, the stroke of the shooting module 10 popping up from the contracted state to the position where the shooting function can be completed is fixed.

Among them, the working state refers to the state where the camera module 10 protrudes from the middle frame surface 800 of the terminal middle frame 20 to the pop-up position and can complete focusing (refer to FIG. 1B); The state of the terminal frame 20 (refer to FIG. 1A ), the position of the movable structure 300 and a port 210 of the waterproof rubber part 200 connected to the moving part 310 of the movable structure 300 is called the initial position.

Simultaneously, when the initial position of a port 210 of the movable part 310 of the waterproof rubber part 200 connected to the movable structure 300 is equal to the position of the other port 220 connected between the waterproof rubber part 200 and the base 400, the redundancy of the waterproof rubber part 200 The remaining length is lower than that of the waterproof rubber part 200 when the initial position of the port 210 connected to the movable part 310 of the movable structure 300 is lower than the position of the other port 220 where the waterproof rubber part 200 is connected to the base 400 The redundant length of is longer.

Therefore, in order to make the best use of the waterproof rubber part 200 without causing waste of the waterproof rubber part 200, in some embodiments of the present application, for the redundant length of the waterproof rubber part 200, it can be connected according to the waterproof rubber part 200. The relative positional relationship between the initial position of one port 210 of the movable structure 300 and the initial position of the other port 220 connecting the waterproof rubber part 200 to the base 400 is designed.

Wherein, the redundant length of the waterproof rubber part 200 refers to the difference between the distance between one port 210 and the other port 220 of the waterproof rubber part 200 and the original length of the waterproof rubber part 200 . That is, the farther the distance between one port 210 of the waterproof rubber part 200 and the other end 220, the smaller the redundant length of the waterproof rubber part 200; the closer the distance between one port 210 of the waterproof rubber part 200 and the other port 220, The redundant length of the waterproof rubber part 200 is larger.

Specifically, FIG. 4A is _a partially enlarged view of the area P1 in FIG. 2A , showing a schematic diagram of the state of the waterproof rubber member 200 when the camera module 10 is in a contracted state. FIG. 4B is a partially enlarged view of P ₂ in FIG. 2B , showing a schematic diagram of the working state of the waterproof rubber part 200 in the camera module 10 . In FIG. 4A and FIG. 4B , the position where the waterproof rubber part 200 is connected to the moving part 310 of the movable structure 300 is the first end 311 .

As shown in Figure 4A, the camera module 10 is in a contracted state, a port 210 of the waterproof rubber part 200 is connected to the first end 311 of the moving part 310 of the movable structure 300, and the other port 220 of the waterproof rubber part 200 is connected to the base The top end 410 of 400 is connected, and the first end 311 of the moving part 310 of the movable structure 300 is at the same level as the top end 410 of the base 400, and the waterproof rubber part 200 is in a redundant state at this time.

As shown in Figure 4B, the camera module 10 is in the pop-up state, a port 210 of the waterproof rubber part 200 is connected to the first end 311 of the moving part 310 of the movable structure 300, and another port 220 higher than the waterproof rubber part 200 is connected At the top 410 of the base 400 , and the lowest end of the moving part 310 of the movable structure 300 is higher than the top 410 of the base 400 , the waterproof rubber part 200 is in a natural state.

Combining FIG. 4A and FIG. 4B , the waterproof rubber part 200 is in a redundant state during the moving process, and the stroke of a port 210 connecting the waterproof rubber part 200 to the first end 311 of the moving part 310 of the movable structure 300 is S ₁ . Moreover, the relative displacement of one port 210 of the waterproof rubber part 200 connected to the first end 311 of the moving part 310 relative to the other port 220 of the waterproof rubber part 200 fixed to the top 410 of the base 400 is also S ₁ .

At this moment, the distance between one port 210 of the waterproof rubber part 200 connected to the moving part 310 of the movable structure 300 and the other port 220 of the waterproof rubber part 200 connected to the top 410 of the base 400 is L ₁ .

5A is _a partially enlarged view of the P1 area in FIG. 2A, showing that the initial position of a port 210 where the waterproof rubber part 200 is connected to the movable structure 300 is lower than the other port 220 where the waterproof rubber part 200 is connected with the base 400 The state diagram of the position. FIG. 5B is a partially enlarged view of the area P2 in FIG. 2B , showing a schematic view of the working state of the waterproof rubber part ₂₀₀ in the camera module 10 . In Fig. 5A and Fig. 5B, the position where the waterproof rubber part 200 is connected to the moving part 310 of the movable structure 300 is the second end 312, and the port 210 where the waterproof rubber part 200 is connected to the movable structure 300 in the contracted state is at a distance from the other end. The vertical distance of one port 220 is equal to the vertical distance between one port 210 connecting the waterproof rubber member 200 and the movable structure 300 to the other port 220 in the pop-up state.

As shown in FIG. 5A , the camera module 10 is in a contracted state, one port 210 of the waterproof rubber part 200 is connected to the second end 312 of the moving part 310 of the movable structure 300, and the other port 220 of the waterproof rubber part 200 is connected to the base The top end 410 of the base 400 is connected, and the second end 312 of the moving part 310 of the movable structure 300 is lower than the top end 410 of the base 400, and the waterproof rubber part 200 is in a natural state at this time.

As shown in Figure 5B, the camera module 10 is in the pop-up state, a port 210 of the waterproof rubber part 200 is connected to the second end 312 of the moving part 310 of the movable structure 300, and the other port 220 of the waterproof rubber part 200 is connected to At the top 410 of the base 400 , and the stroke of a port 210 of the waterproof rubber part 200 is S ₁ , the waterproof rubber part 200 is also in a natural state at this time.

5A and 5B, it can be seen that the stroke of a port 210 connecting the waterproof rubber part 200 to the second end 312 of the movable part 310 of the movable structure 300 is S ₁ , but because the port 210 of the waterproof rubber part 200 is connected to the movable The second end 312 connected to the moving part 310 of the moving structure 300 is originally lower than the other port 220 of the waterproof rubber part 200 and the top 410 of the base 400 (the distance is S ₂ ), so the first port 210 of the waterproof rubber part 200 The relative displacement between the other port 220 connecting the waterproof rubber member 200 to the top 410 of the base 400 is actually ΔS, ie (S ₁ −S ₂ ), and as mentioned above, S ₂ =ΔS.

At this time, the distance between one port 210 of the waterproof rubber part 200 connected to the second end 312 of the movable part 310 of the movable structure 300 and the other port 220 of the waterproof rubber part 200 connected to the top 410 of the base 400 is L ₂ .

Comparing FIG. 4A with FIG. 5A, it can be seen that since the vertical distance L3 between the moving part 310 of the movable structure ₃₀₀ and the base 400 is fixed, for the waterproof rubber part 200 of the same length, when the camera module 10 is in a contracted state , when one port 210 of the waterproof rubber part 200 is connected to the first end 311 of the moving part 310, the distance between one port 210 of the waterproof rubber part 200 and the other port 220 _of the waterproof rubber part 200 is also L3, and When one port 210 of the waterproof rubber part 200 is connected to the second end 312 of the moving part 310 , the distance between one port 210 and the other port 220 of the waterproof rubber part 200 is L ₄ , obviously L ₃ is smaller than L ₄ . Therefore, with the connection method shown in FIG. 4A , the redundant length of the waterproof rubber part 200 is greater than that of the waterproof rubber part 200 when the connection method shown in FIG. 5A is adopted. It can be understood that since in FIG. 5A and FIG. 5B , S ₂ =ΔS, and the waterproof rubber part 200 is in a natural state, so L ₂ is equal to L ₄ .

Therefore, if the waterproof rubber part 200 is connected as shown in FIG. 4A , creases will be formed on the waterproof rubber part 200 , which will accelerate the aging of the waterproof rubber part 200 and shorten the service life of the waterproof rubber part 200 . Therefore, when the lengths of the waterproof rubber parts 200 are the same, the redundancy of the waterproof rubber parts 200 can be reduced by adopting the connection method shown in FIG. The aging degree of the waterproof rubber part 200 is extended.

Comparing Fig. 4B with Fig. 5B, it can be seen that since the vertical distance between the moving part 310 of the movable structure 300 and the base 400 is fixed, and because the waterproof rubber part 200 and the moving part 310 of the movable structure 300 in Fig. A port 210 connected to one end 311, another port 220 connected to the top 410 of the waterproof rubber part 200 and the base 400, the vertical distance between them is S1 _; the waterproof rubber part 200 and the movable structure 300 in Fig. 5B A port 210 connected to the second end 312 of the mobile part 310, and another port 220 connected to the top 410 of the waterproof rubber member 200 and the base 400, the vertical distance between them is ΔS, it can be seen that S1 is greater _than ΔS.

The distance L between a port 210 where the waterproof rubber part 200 is connected to the second end 312 of the movable part 310 of the movable structure 300 in FIG. 5B and another port 220 where the waterproof rubber part 200 is connected to the top 410 of the base 400 ₁ ; a port 210 where the waterproof rubber part 200 is connected to the second end 312 of the movable structure 300 moving part 310 among Fig. 5B, and another port 220 that is connected to the top 410 of the waterproof rubber part 200 and the base 400 is L ₂ , because S ₁ is greater than ΔS, so L ₁ is also greater than L ₂ . That is, the length of the waterproof rubber part 200 when the connection method in FIG. 5A is adopted is smaller than the length of the waterproof rubber part 200 when the connection method in FIG. 4A is adopted. Therefore, when the waterproof rubber part 200 adopts the connection method shown in FIG. 5A and FIG. 5B , the length of the waterproof rubber part 200 can be set shorter.

To sum up, in order to achieve the purpose of saving waterproof rubber materials, when the camera module 10 is in the contracted state, the position of a port 210 connecting the waterproof rubber part 200 to the movable part 310 of the movable structure 300 can be lower than that of the waterproof rubber 200 and the base 400 The position where the top end 410 is connected, that is, the connection method shown in FIG. 5A and FIG. 5B is adopted.

Further, with the above connection method, the waterproof rubber part 200 is in a natural state when the camera module 10 is in a contracted state, and the waterproof rubber part 200 is also in a natural state when the camera module 10 is in a working state, and the waterproof rubber part 200 is only in a movable state. The moving part 310 of the structure 300 is in a redundant state only when it moves relative to the base 400, which effectively reduces the time for the waterproof rubber 200 to be in a redundant state, and avoids the occurrence of damage caused by the waterproof rubber 200 being in a redundant state for a long time. Creases or microcracks will accelerate the aging of the waterproof rubber part 200 to prolong the service life of the waterproof rubber part 200 .

In some embodiments of the present application, the redundant form of the waterproof rubber part 200 can be a relatively gentle multi-wave waterproof rubber 200a as shown in FIG. 6A, or a relatively steep multi-wave waterproof rubber as shown in FIG. 6B. As for the part 200b, it can be understood that when the peak-valley structure of the waterproof rubber part 200 is the same, the greater the number of waveforms, the longer the redundancy;

In some embodiments of the present application, the redundant form of the waterproof rubber part 200 can also be a single wave waterproof rubber part 200c as shown in FIG. 6C, or a non-wave waterproof rubber part 200d as shown in FIG. 6D.

Further, in order to meet the different focusing requirements of different users for the camera module 10, for example, if the user has higher requirements for the pixels of the image captured by the terminal, the corresponding terminal camera needs more lenses, and the corresponding terminal camera module The volume of 10 will also become larger, so that the vertical distance between the pop-up position and the outer surface 800 of the shooting module 10 protruding to the middle frame surface 800 of the terminal middle frame 20 will be higher; The lower it is, the fewer lens groups the corresponding terminal camera needs, and the corresponding terminal shooting module 10 will not protrude particularly, so that the pop-up position of the shooting module 10 protruding to the terminal middle frame 20 is relatively lower than the surface of the middle frame. 800 is also lower. In some other embodiments of the present application, the height of the pop-up position relative to the middle frame surface 800 of the terminal middle frame 200 requires different shooting modules 10, and the redundant length of the waterproof rubber part 200 can also be adjusted according to the height of the shooting module 10. The focus needs to be designed.

Specifically, if the shooting module 10 needs to protrude higher than the position of the frame surface 800 of the terminal middle frame 20 when focusing, a waterproof rubber part 200 with a long redundant length is used to seal the shooting module 10; if When the shooting module 10 completes the shooting function, the lower the pop-up position of the shooting module protruding from the terminal middle frame 20 is, the waterproof rubber piece with a smaller redundant length is used to seal the shooting module 10 . For example, if the focal length of the camera module 10 is greater, then correspondingly, the distance that the camera module 10 needs to protrude to the middle frame surface 800 of the terminal middle frame 20 is greater, so a waterproof rubber with a larger redundant length can be used. Part 200 is used to realize the sealing of the camera module 10 .

Wherein, the relevant description about the redundant length and the corresponding shape of the waterproof rubber part 200 can refer to the introduction of the different lengths corresponding to the different redundant forms of the waterproof rubber part 200 in FIG. 4A to FIG.

The mobile phone 1 realizes the display function through the GPU, the display screen 194, and the application processor. The display screen 194 is used to display images, videos and the like.

The mobile phone 1 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

The ISP is used for processing the data fed back by the camera 193 . For example, when taking a picture, open the shutter, the light is transmitted to the photosensitive element of the camera through the lens, and the light signal is converted into an electrical signal, and the photosensitive element of the camera transmits the electrical signal to the ISP for processing, and converts it into an image visible to the naked eye. ISP can also perform algorithm optimization on image noise, brightness, and skin color. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP may be located in the camera 193 .

Camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects it to the photosensitive element. The photosensitive element may be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, and then transmits the electrical signal to the ISP to convert it into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. DSP converts digital image signals into standard RGB, YUV and other image signals. In some embodiments, the mobile phone 1 may include 1 or N cameras 193, where N is a positive integer greater than 1.

Digital signal processors are used to process digital signals. In addition to digital image signals, they can also process other digital signals. For example, when the mobile phone 1 selects a frequency point, the digital signal processor is used to perform Fourier transform on the energy of the frequency point.

Video codecs are used to compress or decompress digital video. Mobile phone 1 can support one or more video codecs. In this way, the mobile phone 1 can play or record video in multiple encoding formats, for example: moving picture experts group (moving picture experts group, MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

The external memory interface 12 can be used to connect an external memory card. The internal memory 121 may be used to store computer-executable program codes including instructions.

The Hall sensor 18L, the mobile phone 1 can use the Hall sensor 18L to collect the positions of the motor 191 and the camera 193 . In some embodiments, when the mobile phone 1 takes pictures or records videos, the mobile phone 1 can detect the current in the focusing coil of the motor 191 according to the Hall sensor 18L, and then obtain the actual position of the camera 193 according to the detected current.

The pressure sensor 18A is used to sense the pressure signal and convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 18A may be located on the display screen 194 . There are many types of pressure sensors 18A, such as resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors. A capacitive pressure sensor may be comprised of at least two parallel plates with conductive material. When a force is applied to the pressure sensor 18A, the capacitance between the electrodes changes. The mobile phone 1 determines the strength of the pressure based on the change in capacitance. When a touch operation acts on the display screen 194, the mobile phone 1 detects the intensity of the touch operation according to the pressure sensor 18A. The mobile phone 1 can also calculate the touched position according to the detection signal of the pressure sensor 18A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities may correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, an instruction to view short messages is executed. When a touch operation whose intensity is greater than or equal to the first pressure threshold acts on the icon of the short message application, the instruction of creating a new short message is executed.

The gyro sensor 18B can be used to determine the motion posture of the mobile phone 1 . In some embodiments, the angular velocity of the mobile phone 1 about three axes (ie, x, y and z axes) can be determined by the gyro sensor 18B. The gyro sensor 18B can be used for image stabilization. Exemplarily, when the shutter is pressed, the gyro sensor 18B detects the shaking angle of the mobile phone 1, calculates the distance that the lens module needs to compensate according to the angle, and allows the lens to counteract the shaking of the mobile phone 1 through reverse movement to achieve anti-shake. The gyro sensor 18B can also be used for navigation and somatosensory game scenes.

The acceleration sensor 18C can detect the acceleration of the mobile phone 1 in various directions (generally three axes). When the mobile phone 1 is stationary, the magnitude and direction of gravity can be detected. It can also be used to recognize the posture of mobile phones, and can be used in applications such as horizontal and vertical screen switching, pedometers, etc.

FIG. 9 is a block diagram of the software structure of the mobile phone 1 according to the embodiment of the present application. The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the Android system is divided into four layers, which are respectively the application program layer, the application program framework layer, Android runtime (Android runtime, AR) and system libraries, and the kernel layer from top to bottom.

The application layer can consist of a series of application packages.

As shown in FIG. 9, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and short message.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 9, the application framework layer can include window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

A window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the touch screen, capture the touch screen, etc.

Content providers are used to store and retrieve data and make it accessible to applications. Said data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build applications. A display interface can consist of one or more views. Examples include views that display text and views that display images.

The phone manager is used to provide the communication function of the mobile phone 1 .

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears on the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application program running in the background, or a notification that appears on the touch screen in the form of a dialog window. For example, prompting text information in the status bar, issuing a prompt sound, vibrating the electronic device, and flashing the indicator light, etc.

Android Runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

A system library can include multiple function modules. For example: Surface Manager (Surface Manager, SM), Media Library (Media Libraries, ML), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of various commonly used audio and video formats, as well as still image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.
