Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

After long-term research, the inventor of the application finds that the imaging quality of the camera assembly of the electronic equipment is reduced in the using process. For example, the camera assembly may be imaged with black dots or blobs. The reason for the degradation of image quality is that the components of the camera assembly may collide with each other during the manufacturing process of the camera assembly, generating dust or debris. And there are gaps between the components of the camera assembly from which dust or mist can enter the interior space of the camera assembly. Dust or water mist in the internal space of the camera assembly may be deposited and attached to the lens or other optical elements, and block incident light of the camera assembly, resulting in degradation of imaging quality. In the related art, dust or water mist in the internal space of the camera assembly can be removed only by disassembling, cleaning, reassembling and testing. This method can damage the components, and is very likely to be scrapped, which can increase the cost greatly. And electronic equipment is in the in-process of using, and after dust or water smoke got into in camera subassembly inner space, the degree of difficulty and the cost of maintenance are equally higher. In order to improve the above technical problem, the present application proposes the following embodiments.

The handset is the electronic device 1 equipped with a cellular communication module. The mobile phone is illustrated here as an example, but the electronic device 1 is not limited to the mobile phone. The electronic device 1 may also be, for example, a tablet computer, a notebook computer, a wearable device, etc.

The housing 20 and the display screen 30 cooperate to form an accommodating space, and the camera assembly 10 is disposed in the accommodating space. The housing 20 is formed with a through hole through which light passes, and the camera assembly 10 is disposed corresponding to the through hole to receive light incident from the through hole.

Optionally, the display screen 30 may include a touch module, so that a user can perform information interaction with the electronic device 1 by touching the display screen 30, and the information of the interaction can be processed by the electronic control board.

Referring to fig. 1 to 3, in an embodiment of the present application, a camera head assembly 10 includes a lens 12, a driving device 11, and a filter assembly 13.

And a spacing piece can be arranged between every two lenses to adjust the spacing between the lenses and/or shield and eliminate stray light. The lens 12 may also be designed and manufactured according to the related art, and will not be described in detail.

The lens 12 is mounted on the driving device 11 for driving the lens 12 to move. The driving device 11 may be a voice coil motor or a piezoelectric driver, and is not particularly limited herein. The camera module 10 further includes a circuit board 17 and a sensor 18, the circuit board 17 is disposed on the driving device 11 side, and the sensor 18 is disposed on the circuit board 17. External light can be transmitted to the sensor 18 through the lens 12, and the sensor 18 can convert an optical signal into an electrical signal, and then the electrical signal is processed to form an image which can be displayed by the electronic device 1. The driving device 11 can drive the lens 12 to displace, and change the distance between the lens 12 and the sensor 18, thereby achieving the effect of focusing. The driving device 11 is connected to the filter assembly 13, and the filter assembly 13 is disposed between the circuit board 17 and the driving device 11. External light can be transmitted to the filter assembly 13 through the lens 12, the filter assembly 13 can filter light with a specific wavelength, and the light filtered by the filter assembly 13 is transmitted to the sensor 18 and converted into an electric signal. Wherein, human eyes can only receive light rays (namely visible light) in a specific wavelength range. The sensor 18 is capable of receiving the non-visible (e.g., infrared) portion of the light, which may cause the non-visible portion of the light to affect the imaging of the sensor 18. By arranging the filtering component 13, the invisible light part which can be received by the sensor 18 in the light can be filtered, so as to ensure the imaging quality.

Further, the filter assembly 13 includes a carrier 131 and a filter 132, and the filter 132 is disposed on the carrier 131. The stage 131 is disposed between the circuit board 17 and the driving device 11, and is used for carrying the filter 132 and the driving device 11. The filter 132 is disposed corresponding to the lens 12 to receive and filter the light emitted from the lens 12. The optical filter 132 may be a reflective filter or an absorptive filter, and is not limited in this respect. For example, the filter 132 may employ a blue glass infrared cut filter. The filter 132 is disposed corresponding to the sensor 18 so that the light filtered by the filter 132 can be transmitted to the sensor 18.

Further, referring to fig. 3 to 6, the lens 12, the driving device 11 and the filter assembly 13 together enclose an inner space 50 of the camera assembly 10. The camera assembly 10 also includes a heating element 15 and an exhaust vent 16. The heating member 15 is provided in the internal space 50, and the heating member 15 is electrically connected to the circuit board 17 and capable of generating heat to heat the internal space 50. The heating member 15 may be in the form of a heating resistor, a heating pipe, or the like, and is not particularly limited. The exhaust hole 16 communicates the internal space 50 with the outside for exhausting the gas of the internal space 50. Specifically, the heating member 15 may be disposed on a side of the driving device 11 facing the internal space 50 or a side of the stage 131 of the optical filter assembly 13 facing the internal space 50, and is not particularly limited herein. The exhaust hole 16 may be provided in the driving device 11 or in the stage 131 of the filter assembly 13, and is not particularly limited herein. In one embodiment, referring to fig. 6 and 7, the heating element 15 is embedded on the side of the carrier 131 exposed from the inner space 50, and the exhaust hole 16 penetrates through the driving device 11 to communicate the inner space 50 with the outside.

By providing the heating member 15 in the internal space 50 of the camera assembly 10, the internal space 50 can receive heat generated by the heating member 15 and the temperature thereof is increased. After the temperature of the internal space 50 is increased, the water mist in the internal space 50 or attached to the side wall thereof can be converted into water vapor to be mixed with the air, or the attached dust can be dropped to be mixed with the air in the internal space 50. Exhaust hole 16 intercommunication inner space 50 and external world to make the gas that inner space 50 has steam and dust can give vent to anger to the external world from exhaust hole 16, and then realized the dust removal defogging to camera subassembly 10 inside, reduce the influence of dust or water smoke to optical property in the camera subassembly 10, improved the imaging quality, and can reduce camera subassembly 10's maintenance cost.

The following is an exemplary description of the operation of the camera assembly 10 for removing dust and fog:

during the manufacturing or using process of the electronic device 1, the circuit board 17 or a chip in the electronic control board of the electronic device 1 can preview the image of the camera assembly 10, and whether a light-shielding object exists or not can be detected during the preview. Whether dust removal and defogging are needed can be determined by judging whether black spots or black clusters exist in the image. For example, if the light transmittance is detected and the light transmittance is lower than a certain threshold value, it is determined that dust or mist is present in the internal space 50 of the camera module 10. Or judging that the size of the black spot black cluster is larger than a certain threshold value, judging that the internal space 50 has dust or water mist. When it is determined that there is dust or water mist in the interior space 50, the electronic control board can send prompt information to the display 30, so that the user can determine whether to start dedusting and demisting. In other embodiments, the user may also actively trigger the instruction to begin dedusting and defogging.

After the command to start the dust removal and defogging is triggered, the heating elements 15 located in the interior space 50 are activated to vaporize the water mist in the interior space 50 or to shed the dust, so as to fuse the dust or the water mist with the air in the interior space 50. The air in the inner space 50 can be discharged to the outside through the exhaust holes 16, so as to achieve the purpose of removing dust and mist.

The air in the internal space 50 can be exhausted through the exhaust hole 16 after being heated and expanded. The air of the inner space 50 can also create a negative pressure through the air discharge means 40, thereby sucking it out. For example, during the manufacturing process, a dust and mist removing process may be provided, and after the heating member 15 is heated, the external exhaust device 40 may be used to suck the air in the internal space 50 out of the exhaust hole 16. As well, during use, the electronic apparatus 1 may further include an exhaust device 40, the exhaust device 40 being disposed corresponding to the exhaust hole 16 of the camera head assembly 10, for exhausting the gas in the internal space 50 of the camera head assembly 10 through the exhaust hole 16. In the dedusting and demisting process, the chip can simultaneously carry out preview detection on imaging to confirm whether black spot black lumps are eliminated and whether the temperature or airflow needs to be further adjusted.

Referring to fig. 4 to 6, the structure of the driving device 11 will be described exemplarily:

the driving device 11 includes a stator 111 and a mover 112, the mover 112 is movably mounted to the stator 111, and the lens 12 is mounted to the mover 112. The driving device 11 is a voice coil motor for example, and will be further described. A permanent magnet or a coil is mounted in the stator 111, and a permanent magnet or a coil is also mounted in the mover 112. The mover 112 is movable relative to the stator 111 by a force. For example, by supplying current to the coil, the coil is subjected to an ampere force. The mover 112 is capable of moving relative to the stator 111 under the influence or reaction of an ampere force. The lens 12 can be driven to move by the movement of the mover 112, so that the purpose of focusing is achieved. The mover 112 is spaced apart from the stator 111, and a gap 113 is formed between the mover 112 and the stator 111, and the gap 113 communicates the internal space 50 with the outside. Air can enter into the inner space 50 through the gap 113 between the mover 112 and the stator 111. When the exhaust hole 16 is exhausted, air enters the internal space 50 through the gap 113, thereby maintaining the air pressure balance in the internal space 50.

The stator 111 of the driving device 11 is connected to the stage 131 of the filter module 13, and the filter module 13 is disposed on one side of the driving device 11. The heating member 15 may be provided to the stage 131 of the filter assembly 13 or the stator 111 to heat the inner space 50. The exhaust hole 16 may be provided in the stage 131 or the stator 111 of the filter unit 13.

In one embodiment, a gasket 19 is disposed between the stator 111 and the filter assembly 13, and the gasket 19 is disposed on the peripheral side of the filter assembly 13 to prevent gas from entering between the stator 111 and the filter assembly 13. Specifically, the periphery of the stage 131 of the filter assembly 13 is provided with a gasket 19 facing the stator 111, and both sides of the gasket 19 are respectively abutted against the stator 111 and the stage 131 to partially shield a gap therebetween. The gasket 19 is provided so that the stator 111 and the portion of the stage 131 that is not in contact with the gasket 19 are spaced apart from each other. The spaced-apart gap communicates with the interior space 50 or is a portion of the interior space 50. In the present embodiment, the exhaust hole 16 is bent, and one end of the exhaust hole 16 close to the internal space 50 faces the filter assembly 13. That is, one end of the exhaust hole 16 close to the internal space 50 faces a gap between the stage 131 and the stator 111. With such an arrangement, the influence of the opening of the exhaust hole 16 on the installation of the lens 12 and the movement of the mover 112 can be reduced, and the overall structure of the camera assembly 10 can be optimized.

Further, referring to fig. 8 and 9, the camera head assembly 10 further includes an air-lock device 14, wherein the air-lock device 14 is disposed in a gap 113 between the stator 111 and the mover 112, and is used for selectively preventing air from entering the inner space 50 through the gap 113. In the course of performing the dust removal and defogging, the gas in the internal space 50 is discharged through the exhaust hole 16, and the external air enters through the gap between the mover 112 and the stator 111. The air entering from the outside may contain dust or mist, and in order to reduce the secondary pollution of the air entering from the outside to the inner space 50, the air closing device 14 is required to be arranged in the gap 113 between the mover 112 and the stator 111. The selective prevention of gas entry by the gas block 14 may include several aspects, for example, the gas block 14 may move or rotate to open or close part or all of the gap 113 between the mover 112 and the stator 111 to prevent most of the gas from entering the inner space 50 from the gap 113 to reduce the entering dust or mist. As another example, the air-trap 14 may have a selective permeability, allowing clean air to pass through the air-trap 14, and not allowing dust and mist to pass through the air-trap 14, so as to keep the dust and mist out. For another example, the air closing device 14 may combine the above two modes to reduce the entering of dust and water mist, so that the air closing device 14 can reduce the influence on the relative movement of the mover 112 and the stator 111, and increase the reliability of the use of the camera assembly 10.

In one embodiment, the air-lock device 14 includes a driving member 141 and a blocking member 142, and the driving member 141 is mounted to the stator 111 or the mover 112. The driving member 141 is connected with the shutter 142 to drive the shutter 142 to selectively block the gap 113. The driving member 141 can drive the shielding member 142 to move, so that the shielding member 142 shields the gap 113 between the stator 111 and the mover 112, or the shielding member 142 cancels shielding of the gap 113. After the shielding member 142 shields the gap 113, at least part or all of the dust and mist passing through the gap 113 can be shielded and prevented from entering the internal space 50. After the shielding piece 142 cancels shielding of the gap 113, the movement of the mover 112 relative to the stator 111 is less affected by the shielding piece 142, so as to ensure the normal operation of the focusing function of the camera assembly 10. Optionally, the shield 142 is made of a waterproof and air permeable material so that the shield 142 can prevent the ingress of dust mist and can allow the ingress of clean air to reduce the pollution of the interior space 50 caused by the air entering from the gap 113. Alternatively, the gap 113 between the mover 112 and the stator 111 is provided in a ring shape, and the air-lock device 14 may be provided in plural numbers along the gap 113 so as to block the gap 113 as much as possible.

Referring to fig. 9, in an embodiment, the gas closing device 14 further includes a heat conducting member 143, the heat conducting member 143 is mounted on the stator 111, the driving member 141 is a memory alloy, and the memory alloy connects the shielding member 142 and the heat conducting member 143 to drive the shielding member 142 to move. The memory alloy has two-way memory, and can drive the shielding piece 142 to move when the temperature changes; when the temperature is recovered, the shielding piece 142 can be driven to reset. The arrangement of the memory alloy advantageously utilizes the heating element 15 disposed in the interior space 50 as an energy source. By using the memory alloy, the space occupied by the air-lock device 14 can be reduced, which is beneficial to the miniaturization of the camera assembly 10 and can improve the space utilization rate. By providing the heat conducting member 143, the heat generated by the heating member 15 can be efficiently conducted to the memory alloy, so that the memory alloy can be deformed conveniently, and the shielding member 142 can be driven conveniently.

In another embodiment, the shielding member 142 is movably mounted to the mover 112 or the stator 111, the driving member 141 is an electromagnetic driving member, the driving member 141 may be mounted to the mover 112 or the stator 111, and the driving member 141 may be disposed outside the driving device 11. The electromagnetic driving element is magnetically connected with the shutter 142 to drive the shutter 142 to move. The electromagnetic driving method does not require a direct connection between the shielding member 142 and the driving member 141, and the shielding member 142 can be driven by a magnetic field. The electromagnetic driving method can reduce the modification or damage of the structure of the stator 111 or the mover 112 itself due to the installation of the air-lock device 14, improve the stability of the operation of the driving device 11, and reduce the influence of the air-lock device 14 on the driving device 11.

Further, the mover 112 is provided with a bumper 112a at a side facing the filter assembly 13, and the stator 111 is provided with a notch 111a accommodating the bumper 112 a. The bumper 112a is provided to protrude from the mover 112 in a direction toward the filter assembly 13. When the mover 112 moves toward the filter assembly 13, the bumper 112a may abut against the bottom of the notch 111a to limit the stroke of the mover 112, thereby reducing the impact of the mover 112 or the lens 12 on the filter assembly 13 and protecting the filter assembly 13 and the lens 12. The notch 111a communicates the gap 113 with the internal space 50, and air in the gap 113 can enter the internal space 50 through the notch 111 a. The notch 111a is provided such that the air in the gap 113 has a large intake air amount at the notch 111a and a small intake air amount at the other portions. The gas closing means 14 may be provided in correspondence with the notch 111a so as to block the gap 113 at the notch 111a where the amount of intake gas is large, thereby preventing most of the gas from entering into the internal space 50. A small portion of air can enter the interior space 50 from the unobstructed gap 113 to equalize the air pressure of the interior space 50.

The above embodiments are merely examples, and not intended to limit the scope of the present application, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present application, or those directly or indirectly applied to other related arts, are included in the scope of the present application.
