DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0038] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0039] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0040] The first aspect of the present application provides a camera module, such as Figure 1 , Figure 2 and Figure 3 As shown, the camera module includes a housing 1, a lens 2, a photosensitive part 3 and a focusing mechanism 4. The housing 1 is fixedly connected to the lens 2. The photosensitive part 3 is stacked with the lens 2. The focusing mechanism 4 is connected to the photosensitive part 3 so as to be able to drive the photosensitive part 3 to approach and move away from the lens 2.

[0041] In the embodiment of the present application, the focusing mechanism 4 can adjust the relative position between the photosensitive part 3 and the focus by driving the photosensitive part 3 to approach and move away from the lens 2, so as to improve the imaging quality of the camera module of the present application. The housing 1 is fixedly connected to the lens 2, so as to prevent the lens 2 from being hit by the outside world or driven by the driving component, and from impacting the housing 1, so as to reduce the damage of the camera module during use. At the same time, the restricted movement of the lens 2 is also conducive to the relative isolation of the inside of the housing 1 from the outside world, which can reduce the pollution of the camera module of the present application by impurities such as dust, so as to maintain its imaging quality after a period of use and improve durability.

[0042] In the embodiment of the present application, the housing 1 can be used as a component for supporting the lens 2, and can also be used as a component for supporting the focusing mechanism 4 and the photosensitive part 3. The focusing mechanism 4 and the photosensitive part 3 can be connected to the housing 1 to realize their functions. The housing 1 can include multiple sub-components, and the multiple sub-components cooperate with each other to form the housing 1. The lens 2 is connected to one or more of the sub-components to facilitate the disassembly and replacement of the lens 2.

[0043] In the embodiment of the present application, the lens 2 can capture the optical signal of the object being photographed. The lens 2 can be connected to the housing 1 by a detachable connection such as a bolt connection, so as to limit the relative movement of the lens 2 relative to the housing 1.

[0044] In the embodiment of the present application, the photosensitive part 3 can sense the light signal from the lens 2 and convert the light signal into an electrical signal. The electrical signal can form an image. The photosensitive part 3 can be a photoelectric sensor such as a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS).

[0045] In the embodiment of the present application, the focusing mechanism 4 can adjust the distance between the lens 2 and the photosensitive part 3, thereby achieving focusing.

[0046] In the embodiment of the present application, the housing 1 can be connected to the lens 2 by using processes such as bonding and integral molding to limit the movement of the lens 2 relative to the housing 1.

[0047] In the embodiment of the present application, the stacked arrangement of the photosensitive portion 3 and the lens 2 is conducive to light directly passing through the lens 2 and falling on the photosensitive portion 3, which is conducive to forming an image.

[0048] In the embodiment of the present application, the focus mechanism 4 is connected to the photosensitive part 3 so as to be able to drive the photosensitive part 3 to approach and move away from the lens 2. The focus mechanism 4 can achieve focusing by directly driving the photosensitive part 3 to approach and move away from the lens 2, or can drive the photosensitive part 3 to approach or move away from the lens 2, and generate a restoring force to force the photosensitive part 3 to return to the initial position when the photosensitive part 3 approaches or moves away from the lens 2, and after focusing and shooting are completed, the photosensitive part 3 returns to the initial position.

[0049] In some of the embodiments of this application, Figure 3 As shown, the focusing mechanism 4 includes a driving component 41 and a resetting component 42. The driving component 41 is connected to the photosensitive part 3 to drive the photosensitive part 3 to approach the lens 2. The resetting component 42 is used to provide a resetting force to the photosensitive part 3 when the photosensitive part 3 approaches the lens 2.

[0050] In the embodiment of the present application, the driving component 41 can adjust the distance between the lens 2 and the photosensitive part 3 to achieve focusing by driving the photosensitive part 3 to approach the lens 2. After completing the focusing and shooting, the driving component 41 stops driving the photosensitive part 3, so that the reset component 42 can drive the photosensitive part 3 to return to the initial position, which is conducive to the next focusing.

[0051] In the embodiment of the present application, the driving component 41 can directly contact with the photosensitive part 3 to generate a force to achieve focusing. The driving component 41 is in contact with the photosensitive part 3 through a push rod and other structures.

[0052] In some of the embodiments of this application, Figure 3 As shown, the reset assembly 42 includes a connecting portion 421 and a sealed cavity 420. The sealed cavity 420 is located on the side of the photosensitive portion 3 away from the lens 2. At least a portion of the connecting portion 421 is located in the sealed cavity 420. The connecting portion 421 is connected to the photosensitive portion 3 and can move closer to the lens 2 with the photosensitive portion 3.

[0053] It is understandable that the sealed cavity 420 has a certain pressure, and when the connecting portion 421 approaches the lens 2 under the action of the photosensitive portion 3, the pressure in the sealed cavity 420 can change, so that the external air generates a restoring force on the connecting portion 421 and acts on the photosensitive portion 3. The photosensitive portion 3 subjected to the restoring force can return to the initial position under the action of the driving assembly 41 when the driving force is removed.

[0054] In the embodiment of the present application, when in the initial position, the pressure in the sealed cavity 420 of the photosensitive portion 3 is equal to the atmospheric pressure.

[0055] In some of the embodiments of this application, Figure 3 As shown, the reset assembly 42 includes a support portion 422 , which is sleeved on the outside of the connecting portion 421 and connected to the side wall of the sealing cavity 420 .

[0056] It can be understood that the supporting portion 422 can support the connecting portion 421 , which is beneficial for the connecting portion 421 to move with the photosensitive portion 3 .

[0057] In some of the embodiments of this application, Figure 3 As shown, the support portion 422 includes a shell 4221 and a rolling body 4222. The shell 4221 is sleeved on the outside of the connecting portion 421 and connected to the side wall of the sealing cavity 420. The rolling body 4222 is located between the connecting portion 421 and the shell 4221 and can roll relative to the connecting portion 421 and the shell 4221.

[0058] It can be understood that the outer shell 4221 is sleeved on the outer side of the connecting portion 421 and connected to the side wall of the sealing cavity 420, providing support for the rolling body 4222. The rolling body 4222 rolls relative to the connecting portion 421 and the outer shell 4221, which can replace the sliding between the connecting portion 421 and the side wall of the sealing cavity 420, which is conducive to the connecting portion 421 changing the pressure in the sealing ring.

[0059] In the embodiment of the present application, the rolling body 4222 can be a sphere, a cylinder, a needle roller or other structures.

[0060] In the embodiment of the present application, the support portion 422 may further include a retaining frame, which serves to limit the rolling body 4222 and prevent it from falling off between the connecting portion 421 and the outer shell 4221 .

[0061] In some of the embodiments of this application, Figure 3 As shown, the reset assembly 42 further includes a sealing portion 423 , the sealing cavity 420 has a first opening 4201 , a portion of the connecting portion 421 extends from the first opening 4201 into the sealing cavity 420 , and the sealing portion 423 seals the first opening 4201 .

[0062] It is understandable that the first opening 4201 facilitates the connection part 421 to extend into the sealed cavity 420, so that the connection part 421 is subjected to the pressure in the sealed cavity 420 to generate a reset force on the photosensitive part 3. The sealing part 423 seals the first opening 4201, which can improve the sealing performance of the sealed cavity 420 and reduce the situation where the outside air enters the sealed cavity 420. This is conducive to maintaining the reset effect generated by the reset component 42.

[0063] In the embodiment of the present application, the sealing portion 423 may be made of an elastic material such as rubber, and seals the first opening 4201 .

[0064] In some embodiments of the present application, the air pressure in the sealed cavity 420 is less than the standard atmospheric pressure.

[0065] It is understandable that such a configuration is beneficial for the external air to generate pressure on the photosensitive part 3 when the connecting part 421 and the photosensitive part 3 are close to the lens 2. The pressure is the restoring force.

[0066] In some embodiments of the present application, the driving component 41 includes a magnet 411 and a coil 412 . The magnet 411 and the coil 412 are arranged relatively to each other along the moving direction of the photosensitive portion 3 , and the magnet 411 is connected to the photosensitive portion 3 .

[0067] It is understandable that when the coil 412 is energized, the magnetism of the side facing the magnet 411 is the same as that of the magnet 411, thus generating a repulsive force. The repulsive force is along the moving direction of the photosensitive part 3, so that the photosensitive part 3 is close to the lens 2, thus achieving focusing.

[0068] In some of the embodiments of this application, Figure 3 As shown, the driving component 41 includes a magnet 411 and a coil 412 . The magnet 411 and the coil 412 are arranged relatively to each other along the moving direction of the photosensitive portion 3 , and the coil 412 is connected to the photosensitive portion 3 .

[0069] It is understandable that when the coil 412 is energized, the magnetism of the side facing the magnet 411 is the same as that of the magnet 411, thus generating a repulsive force. The repulsive force is along the moving direction of the photosensitive part 3, so that the photosensitive part 3 is close to the lens 2, thus achieving focusing.

[0070] In some embodiments of the present application, the coil 412 is electrically connected to the photosensitive portion 3 .

[0071] In the embodiment of the present application, the photosensitive part 3 is electrically connected to the coil 412, and the coil 412 can be powered to generate a magnetic field to repel the magnet 411. In this way, the distance between the photosensitive part 3 and the lens 2 can be adjusted to achieve the focusing function.

[0072] In some of the embodiments of this application, Figure 3 As shown, the number of the driving components 41 is at least two, and two of the at least two driving components 41 are respectively located on two opposite sides of the reset portion.

[0073] It is understandable that the two driving components 41 can generate driving forces at different positions of the photosensitive part 3, so that the focusing of the photosensitive part 3 can be achieved. The driving forces generated by the two driving components 41 can form a balanced state with the reset force generated by the reset component 42. This state is conducive to improving the photosensitive part 3 to maintain a relatively stable state when it is close to the lens 2, so as to complete the focusing.

[0074] In some of the embodiments of this application, Figure 4 As shown, the housing 1 has a housing cavity 100 , the housing cavity 100 has a second opening 101 , the photosensitive portion 3 is located in the housing cavity 100 , and the lens 2 seals the second opening 101 .

[0075] It is understandable that the accommodating cavity 100 can accommodate the lens 2 and the photosensitive part 3. The second opening 101 is conducive to the photosensitive part 3 being placed in the accommodating cavity 100, and the housing 1 protects and supports the photosensitive part 3. The lens 2 seals the second opening 101, which can reduce the external impurities from contacting the photosensitive part 3 through the second opening 101, so that the sealing of the accommodating cavity 100 can be improved, and the photosensitive part 3 can be prevented from being contaminated.

[0076] In the embodiment of the present application, the lens 2 can be connected to the housing 1 through a bonding or one-piece molding process, thereby sealing the second opening 101 .

[0077] In some of the embodiments of this application, Figure 3 and Figure 5 As shown, the camera module includes a power supply 5 , the accommodating cavity 100 has a third opening 102 , the power supply 5 seals the third opening 102 , and the power supply 5 is electrically connected to the photosensitive portion 3 .

[0078] In the embodiment of the present application, the power supply 5 is electrically connected to the photosensitive part 3, and can supply power to the photosensitive part 3. The third opening 102 is helpful for designers to arrange the position of the photosensitive part 3. By sealing the third opening 102 by the power supply 5, the contamination of the photosensitive part 3 by external impurities is reduced. The power supply 5 located at the third opening 102 can also be supported by the housing 1 to improve its stability.

[0079] In the embodiment of the present application, the power supply 5 can be connected to the housing 1 by bonding or integral molding, thereby sealing the third opening 102 .

[0080] In some of the embodiments of this application, Figure 1 As shown, the camera module also includes a filter 6, which is located between the lens 2 and the photosensitive part 3.

[0081] It can be understood that the filter 6 helps the camera module of the present application to select the light that contacts the photosensitive part 3 and reduce the influence of stray light on the photosensitive part 3, thereby improving the imaging quality of the photosensitive part 3.

[0082] A second aspect of the present application provides an electronic device, which includes a camera module as described in the above embodiment.

[0083] It can be understood that, due to the adoption of the camera module of the above-mentioned embodiment, the electronic device of the present application has the same technical effect as the above-mentioned camera module, which will not be repeated here.

[0084] In the embodiment of the present application, the electronic device may be a product such as a smart phone, a smart watch, a laptop computer or a tablet computer.

[0085] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
