For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0013] The camera module and its installation method, and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0014] refer to Figure 1-Figure 3 The camera module disclosed in the embodiment of the present application includes a lens barrel 100, a first lens 200 and a second lens 300. The lens barrel 100 serves as an installation base for the first lens 200 and the second lens 300, and the first lens 200 and the second lens 300 are respectively installed in the lens barrel 100.

[0015] Specifically, refer to Figure 1 As shown, the lens barrel 100 includes a first barrel portion 110, a connecting portion 120 and a second barrel portion 130 which are connected in sequence and formed in one piece, a first lens 200 is disposed in the first barrel portion 110, and a second lens 300 is disposed in the second barrel portion 130. Specifically, the first barrel portion 110 forms a first chamber, the first chamber serves as a mounting chamber for the first lens 200, the first lens 200 is disposed in the first chamber, and the second barrel portion 130 forms a second chamber, the second chamber serves as a mounting chamber for the second lens 300, and the second lens 300 is disposed in the second chamber. The number of the first lens 200 may be one or more, the first lens 200 and the first barrel portion 110 form a first lens group, the number of the second lens 300 may be one or more, the second lens 300 and the second barrel portion 130 form a second lens group.

[0016] Optionally, the first barrel 110, the connecting portion 120 and the second barrel 130 are sequentially arranged along the axial direction of the lens barrel 100. The lens barrel 100 may be made of plastic, and the first barrel 110, the connecting portion 120 and the second barrel 130 may be formed into an integral structure by injection molding. Alternatively, the lens barrel 100 may be made of metal, and the first barrel 110, the connecting portion 120 and the second barrel 130 may be formed into an integral structure by casting. Of course, the lens barrel 100 may also be made of other materials.

[0017] Optionally, the structures and sizes of the first barrel 110 and the second barrel 130 may be the same or different, and the connecting portion 120 may be a connecting strip, a connecting block, etc. The embodiment of the present application does not limit the specific structure of the connecting portion 120, and the first barrel 110 and the second barrel 130 can be connected to realize an integrated molding process of the lens barrel 100.

[0018] In this arrangement, only one lens barrel 100 is needed to simultaneously install the first lens 200 and the second lens 300, thereby forming different lens groups. It is not necessary to produce a lens barrel 100 for each lens group separately, and the number of lens barrels 100 produced is reduced, which is conducive to saving production costs, and the lens barrel 100 is integrally formed, which is conducive to simplifying the production process. After the first lens 200 and the second lens 300 are installed in the lens barrel 100, the lens barrel 100 can be directly installed, which is conducive to simplifying the assembly process, ensuring that the relative position of the first lens 200 and the second lens 300 is accurate, that is, the relative position of the lens of the first lens group and the lens of the second lens group is accurate, avoiding a large position deviation between the two after installation and affecting the camera performance of the camera module.

[0019] In addition, each lens group needs to be tested. In this case, since one lens barrel 100 is used, the camera module only needs to be tested once, which reduces the number of tests and helps to reduce the difficulty of testing.

[0020] The connecting portion 120 is a breakable structure. When the connecting portion 120 is subjected to an external force, the connecting portion 120 is in a disconnected state to separate the first barrel portion 110 from the second barrel portion 130. Optionally, the connecting portion 120 may be a plastic structure or a metal structure, and the connecting portion 120 may be broken by cutting, and the cutting method may be laser cutting or ultrasonic cutting, etc., and the external force comes from the cutting force. The connecting portion 120 may also be broken by etching, and the external force is an etching force. Of course, other methods that can break the connecting portion 120 may also be used, as long as the first barrel portion 110 and the second barrel portion 130 can be separated.

[0021] With such arrangement, after the lens barrel 100 is installed, the connecting portion 120 can be broken to separate the first barrel portion 110 and the second barrel portion 130 , and the first barrel portion 110 and the second barrel portion 130 can move relative to each other to adjust the distance between the first lens 200 and the second lens 300 to achieve focusing.

[0022] In an optional embodiment, the connecting portion 120 may be a connecting ring, a first end of the connecting ring is connected to the first barrel portion 110 , and a second end of the connecting ring is connected to the second barrel portion 130 .

[0023] In another embodiment, the connecting portion 120 includes a connecting rib, which is a strip-shaped structure. A first end of the connecting rib is connected to the first barrel portion 110 , and a second end of the connecting rib is connected to the second barrel portion 130 .

[0024] With this embodiment, the volume of the connecting rib is relatively small, which is beneficial to reducing the fracture area and shortening the fracture time. After the lens barrel 100 is installed, it is more beneficial to quickly separate the first barrel portion 110 and the second barrel portion 130.

[0025] In an optional embodiment, the number of the connecting rib is one.

[0026] In another embodiment, a plurality of connecting ribs are arranged at intervals in the circumferential direction of the lens barrel 100. Optionally, the plurality of connecting ribs may be evenly or unevenly distributed in the circumferential direction of the lens barrel 100, and the structure of each connecting rib may be the same or different. In this embodiment, the number of connecting ribs is two, and the two connecting ribs are arranged opposite to each other. Of course, the connecting ribs may also be arranged in other numbers.

[0027] With this embodiment, the number of connecting ribs increases, and the area where the first barrel portion 110 and the second barrel portion 130 are connected by the connecting ribs increases, which is conducive to a more stable connection between the first barrel portion 110 and the second barrel portion 130.

[0028] In an alternative embodiment, reference Figure 1 As shown, the connection portion 120 is provided with a marking structure 121 for indicating the fracture position. Optionally, the marking structure 121 can be a scale line, a marking groove, or other structures. The embodiment of the present application does not limit the specific form of the marking structure 121, as long as it can indicate the fracture position.

[0029] Further optionally, when the marking structure 121 is a marking groove, the marking groove can be directly formed when the lens barrel 100 is produced; when the marking structure 121 is a scale line, it can be manually marked after the lens barrel 100 is produced.

[0030] According to this embodiment, by setting the marking structure 121, it is helpful to accurately determine the fracture position and ensure the fracture position is accurate.

[0031] Of course, in other embodiments, the connection portion 120 may not be provided with the marking structure 121 , and any position of the connection portion 120 may be broken to separate the first barrel portion 110 and the second barrel portion 130 .

[0032] In an optional embodiment, the connection between the connection part 120 and the first barrel part 110 is a first connection, the connection between the connection part 120 and the second barrel part 130 is a second connection, and the marking structure 121 is located between the first connection and the second connection. Along the direction from the first connection to the marking structure 121, and along the direction from the second connection to the marking structure 121, the size of the connection part 120 is constant, and optionally, along the axial direction of the lens barrel 100, the size of the connection part 120 does not change.

[0033] It should be noted that the size of the connecting portion 120 refers to the size in the direction perpendicular to the axis of the lens barrel 100. Optionally, the connecting portion 120 is a connecting rib, and the number of the connecting ribs is two, in which case the size of the connecting portion 120 refers to the size in the direction in which the two connecting ribs are arranged.

[0034] In another embodiment, the size of the connection portion 120 decreases along the direction from the first connection to the marking structure 121 and along the direction from the second connection to the marking structure 121. That is, the closer to the first barrel 110, the larger the size of the connection portion 120. Similarly, the closer to the second barrel 130, the larger the size of the connection portion 120. The closer to the marking structure 121, the smaller the size of the connection portion 120.

[0035] Optionally, the connecting portion 120 may be provided with a groove, the groove comprising a first groove wall surface and a second groove wall surface that are connected, the first groove wall surface and the second groove wall surface are respectively inclined relative to the axis of the lens barrel 100, and the marking structure 121 is located at the connection between the first groove wall surface and the second groove wall surface. Further optionally, the first groove wall surface and the second groove wall surface may be a plane or a curved surface.

[0036] With this embodiment, the size of the connecting portion 120 at the marking structure 121 is relatively small, and the fracture is performed at the marking structure 121, so that the fracture area is smaller, which is beneficial to shorten the duration of the fracture. After the lens barrel 100 is installed, it is more conducive to the rapid separation of the first barrel portion 110 and the second barrel portion 130.

[0037] In an optional embodiment, the port of the first barrel 110 away from the second barrel 130 is the first mounting port 110a, and the port of the second barrel 130 away from the first barrel 110 is the second mounting port 130a. The first lens 200 can be arranged in the first barrel 110 through the first mounting port 110a, and the second lens 300 can be arranged in the second barrel 130 through the first mounting port 110a, or the first lens 200 can be arranged in the first barrel 110 through the second mounting port 130a, and the second lens 300 can be arranged in the second barrel 130 through the second mounting port 130a. In other words, the first lens 200 and the second lens 300 can be installed from the same side of the lens barrel 100.

[0038] In another embodiment, the first lens 200 is disposed in the first barrel 110 through the first mounting opening 110a, and the second lens 300 is disposed in the second barrel 130 through the second mounting opening 130a. In other words, the first lens 200 and the second lens 300 are installed from both sides of the lens barrel 100, respectively.

[0039] In this embodiment, the first mounting port 110a is closer to the mounting position of the first lens 200, and the second mounting port 130a is closer to the mounting position of the second lens 300. Therefore, the first lens 200 and the second lens 300 are installed respectively using the first mounting port 110a and the second mounting port 130a. The first lens 200 does not need to be installed to the first barrel 110 from the second mounting port 130a via the connecting portion 120, and the second lens 300 does not need to be installed to the second barrel 130 from the first mounting port 110a via the connecting portion 120. This makes the installation process of the first lens 200 and the second lens 300 more convenient, and also avoids the installation process of the first lens 200 and the second lens 300 from affecting the connecting portion 120.

[0040] In an optional embodiment, the port of the first barrel portion 110 close to the second barrel portion 130 is the first port 110 b , and the caliber of the first installation port 110 a may be equal to the caliber of the first port 110 b .

[0041] In another embodiment, the diameter of the first installation opening 110a is larger than the diameter of the first port 110b. Figure 1-Figure 3 As shown, the inner wall surface of the first barrel portion 110 may be a conical surface or a stepped surface, and the inner wall surface of the first barrel portion 110 may also be set to other structures, as long as the diameter of the first installation opening 110a is larger than the diameter of the first port 110b.

[0042] Optionally, along a direction perpendicular to the axis of the lens barrel 100, the cross-sectional shape of the inner wall surface of the first barrel portion 110 can be a circular structure, and the first lens 200 is a circular lens. Of course, the cross-sectional shape of the inner wall surface of the first barrel portion 110 can also be other structures, and the embodiment of the present application does not limit this.

[0043] In this embodiment, the first installation opening 110 a has a larger diameter, which makes it easier for the first lens 200 to extend into the first barrel 110 , thereby achieving the installation process of the first lens 200 .

[0044] In an optional embodiment, the port of the second barrel portion 130 close to the first barrel portion 110 is the second port 130 b , and the caliber of the second installation port 130 a is equal to the caliber of the second port 130 b .

[0045] In another embodiment, the diameter of the second installation opening 130a is larger than the diameter of the second port 130b. Figure 1-Figure 3 As shown, the inner wall surface of the second barrel portion 130 may be a conical surface or a stepped surface, and the inner wall surface of the second barrel portion 130 may also be set to other structures, as long as the diameter of the second installation opening 130a is larger than the diameter of the second port 130b.

[0046] Optionally, along a direction perpendicular to the axis of the lens barrel 100, the cross-sectional shape of the inner wall surface of the second barrel portion 130 can be a circular structure, and the second lens 300 is a circular lens. Of course, the cross-sectional shape of the inner wall surface of the second barrel portion 130 can also be other structures, and the embodiment of the present application does not limit this.

[0047] With this embodiment, the second installation opening 130 a has a larger diameter, which makes it easier for the second lens 300 to extend into the second barrel 130 , thereby achieving the installation process of the second lens 300 .

[0048] In an optional embodiment, the camera module also includes a spacer 400, which is used to separate adjacent lenses and improve imaging stray light and other problems caused by the edges of the lenses. There are multiple first lenses 200, and multiple first lenses 200 and the first barrel 110 form a first lens group. The first lenses 200 are arranged at intervals along the axial direction of the first barrel 110, and a spacer 400 is provided between two adjacent first lenses 200 to separate the two adjacent first lenses 200 through the spacer 400; there are multiple second lenses 300, and multiple second lenses 300 and the second barrel 130 form a second lens group. The second lenses 300 are arranged at intervals along the axial direction of the second barrel 130, and a spacer 400 is provided between two adjacent second lenses 300 to separate the two adjacent second lenses 300 through the spacer 400.

[0049] Based on the camera module disclosed in this application, an embodiment of this application also discloses an electronic device, wherein the electronic device includes a device housing and the camera module, and the camera module is arranged in the device housing to realize the camera function of the electronic device. Of course, in addition to the device housing and the camera module, the electronic device may also include functional devices such as circuit boards and sensors.

[0050] With this embodiment, the camera module of the electronic device is provided with an integrally formed lens barrel 100 to respectively install the first lens 200 and the second lens 300, and after the lens barrel 100 is installed, the relative position of the first lens 200 and the second lens 300 is accurate, so as to avoid a large position deviation between the two and affect the camera performance of the camera module. Moreover, after the lens barrel 100 is installed, the connecting portion 120 can be broken to separate the first barrel portion 110 and the second barrel portion 130, and the first barrel portion 110 and the second barrel portion 130 can move relative to each other to adjust the distance between the first lens 200 and the second lens 300 to achieve focusing, without affecting the camera function of the camera module.

[0051] In addition, each lens group needs to be tested. In this case, since one lens barrel 100 is used, the camera module only needs to be tested once, which reduces the number of tests and helps to reduce the difficulty of testing.

[0052] In an optional embodiment, the first barrel portion 110 is movable relative to the second barrel portion 130 , and focusing can be achieved by manually adjusting the position of the first barrel portion 110 relative to the second barrel portion 130 .

[0053] In another embodiment, reference Figure 2 and Figure 3 As shown, the electronic device further includes a driving mechanism 500, which includes a driving fixed member 510 and a driving movable member 520. The driving movable member 520 can move relative to the driving fixed member 510, the first barrel 110 is connected to the driving movable member 520, and the second barrel 130 is connected to the driving fixed member 510. Optionally, the first barrel 110 and the driving movable member 520 can be fixedly connected by bonding, welding, etc.; the second barrel 130 and the driving movable member 520 can be fixedly connected by a connecting glue 511. Of course, the two can also be fixedly connected by welding, etc.

[0054] The driving fixed member 510 interacts with the driving movable member 520, and the driving movable member 520 moves relative to the driving fixed member 510, so that the driving movable member 520 drives the first barrel 110 to move axially relative to the second barrel 130 along the lens barrel 100, thereby adjusting the distance between the first lens 200 and the second lens 300 to achieve focusing of the camera module.

[0055] Optionally, the driving mechanism 500 may be a zoom motor, which may include a magnetic part and a coil. When the coil is energized, the coil generates a magnetic field, the magnetic part is subjected to the Lorentz force in the magnetic field, and the magnetic part and the coil generate relative motion. When the position of the coil is fixed, the coil is the driving fixed part 510, and the magnetic part is the driving movable part 520; when the position of the magnetic part is fixed, the coil is the driving movable part 520, and the magnetic part is the driving fixed part 510. Of course, the zoom motor may also use structures other than the magnetic part and the coil to drive the first barrel 110 to move, and the driving mechanism 500 may also use other driving parts other than the zoom motor.

[0056] In addition, the zoom motor also includes a shell 530, and the driving fixed part 510 and the driving movable part 520 are both arranged in the shell 530. The shell 530 is also provided with an incident port 531. A reflector 700 is provided in the shell 530. The reflector 700 can be but is not limited to a prism. The light incident surface of the reflector 700 is opposite to the incident port 531, and the light emitting surface of the reflector 700 is opposite to the second barrel 130. A photosensitive chip is provided on the side of the lens barrel 100 facing away from the reflector 700. In this way, light enters the shell 530 through the incident port 531, and passes through the reflector 700, the second lens 300 and the first lens 200 in sequence to finally reach the photosensitive chip to achieve imaging.

[0057] With this embodiment, the camera module is directly installed inside the driving mechanism 500, and the different components of the driving mechanism 500 are respectively connected to the first barrel 110 and the second barrel 130. The driving movable part 520 is used to drive the first barrel 110 to move relative to the second barrel 130, which is beneficial for the first barrel 110 to quickly move to the focusing position and realize fast focusing without manual focusing.

[0058] In an alternative embodiment, reference Figure 2 and Figure 3 As shown, the electronic device further includes a guide track 610 and a guide member, one of the housing 530 and the first barrel 110 is provided with the guide track 610, the other of the housing 530 and the first barrel 110 is connected to the guide member, the extension direction of the guide track 610 is parallel to the axial direction of the lens barrel 100, and the guide track 610 is guided and matched with the guide member. In this arrangement, the guide track 610 and the guide member are used to guide the movement direction of the first barrel 110, which is conducive to the first barrel 110 accurately moving relative to the second barrel 130 along the axial direction of the lens barrel 100, and accurately adjusting the focal length of the camera module.

[0059] Optionally, the other of the housing 530 and the first barrel 110 is provided with an arc groove, the guide member can be a ball 620, the first part of the ball 620 is located in the arc groove, and the other part of the ball 620 extends into the guide track 610. When the first barrel 110 moves relative to the second barrel 130, the ball 620 rolls in the arc groove, the position of the ball 620 relative to the arc groove is fixed, and the ball 620 rolls in the guide track 610. In this way, the friction between the ball 620 and the guide track 610 is rolling friction, and the friction is small, which is conducive to the first barrel 110 to move more smoothly relative to the second barrel 130.

[0060] The electronic device disclosed in the embodiments of the present application may be a smart phone, a tablet computer, an e-book reader, a wearable device, an electronic game console, or the like. The embodiments of the present application do not limit the specific types of electronic devices.

[0061] Based on the camera module disclosed in the present application, the present application embodiment further discloses a method for installing the camera module, which specifically includes: S100, forming an integrally formed lens barrel 100, wherein the lens barrel 100 comprises a first barrel portion 110, a connecting portion 120 and a second barrel portion 130 connected in sequence. Optionally, the lens barrel 100 may be made of plastic material and formed into an integrally formed lens barrel 100 by injection molding; or, the lens barrel 100 may be made of metal material and formed into an integrally formed lens barrel 100 by casting.

[0062] S200, Reference Figure 1 As shown, the first lens 200 is installed into the first barrel 110 through the first installation opening 110a, and the second lens 300 is installed into the second barrel 130 through the second installation opening 130a, wherein the first installation opening 110a is the end of the first barrel 110 away from the second barrel 130, and the second installation opening 130a is the end of the second barrel 130 away from the first barrel 110. In other words, the first lens 200 and the second lens 300 are installed from both sides of the lens barrel 100, respectively.

[0063] The first mounting port 110a is relatively close to the mounting position of the first lens 200, and the second mounting port 130a is relatively close to the mounting position of the second lens 300. Therefore, the first lens 200 and the second lens 300 are respectively mounted using the first mounting port 110a and the second mounting port 130a. The first lens 200 does not need to be mounted to the first barrel 110 via the connecting portion 120 from the second mounting port 130a, and the second lens 300 does not need to be mounted to the second barrel 130 via the connecting portion 120 from the first mounting port 110a. This makes the mounting process of the first lens 200 and the second lens 300 more convenient, and also prevents the mounting process of the first lens 200 and the second lens 300 from affecting the connecting portion 120.

[0064] S300, installing the lens barrel 100. Optionally, the first barrel portion 110 and the second barrel portion 130 of the lens barrel 100 are respectively connected to different parts of the driving mechanism 500 of the electronic device, specifically, the first barrel portion 110 is connected to the magnetic member, and the second barrel portion 130 is connected to the coil, so as to install the camera module.

[0065] S400, applying a force to the connection part 120 to put the connection part 120 in a broken state, so as to separate the first barrel part 110 and the second barrel part 130. Optionally, the connection part 120 may be cut by laser cutting or ultrasonic cutting to break the connection part 120, so as to separate the first barrel part 110 and the second barrel part 130, in which case the force is a cutting force; or the connection part 120 may be broken by etching to separate the first barrel part 110 and the second barrel part 130, in which case the force is an etching force.

[0066] By using the above-mentioned installation method, the first lens 200 and the second lens 300 are first installed to the same lens barrel 100, and then the connecting portion 120 of the lens barrel 100 is broken to form the first lens group and the second lens group. The first lens group and the second lens group can move relative to each other to adjust the distance between the first lens 200 and the second lens 300 to achieve focusing. In this way, only one lens barrel 100 needs to be produced, which is conducive to saving production costs, and after the camera module is installed, the installation position of the first lens 200 and the second lens 300 is guaranteed to be accurate, so as to avoid the position deviation of the two being large and affecting the camera performance of the camera module. In addition, each lens group needs to be tested. In this case, since one lens barrel 100 is used, only the camera module needs to be tested once, which reduces the number of tests and helps to reduce the difficulty of the test.
