[0044] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below with reference to the drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions in the embodiments of this specification, rather than limitations on the technical solutions of this specification. Without conflict, the technical features in the embodiments of this specification and the embodiments can be combined with each other.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element. The term "more than two" includes two or more than two.

[0046] Please refer to the attached Figures 1-5 to describe the assembly method of the camera module according to the embodiments of the present application.

[0047] It can be understood that the camera module 100 of the present application includes, but is not limited to, a vertical camera module or a horizontal camera module. The camera module 100 can be used in shooting devices such as cameras. The camera module 100 can include a first module and a second module. The first module includes a lens 30, and the second module includes a motor 10. The motor 10 has a first housing 20, and the first housing 20 is provided with a first opening 201.

[0048] As Figure 1 shown, the assembly method of the camera module includes:

[0049] S10: Control the first module and / or the second module to move along the Z direction of the optical axis of the lens 30 until the first module extends into a preset position inside the first housing 20 from the first opening 201.

[0050] For example, control the first module to move along the Z direction of the optical axis until the first module extends from the first opening 201 to a preset position inside the first housing 20, or control the second module to move along the Z direction of the optical axis until the first module extends from the first opening 201 to a preset position inside the first housing 20, or control the first module and the second module to move towards each other along the Z direction of the optical axis until the first module extends from the first opening 201 to a preset position inside the first housing 20.

[0051] It can be understood that the preset position refers to the designed position. Generally, it is the position of the first module when a part of the first module is inside the first housing 20 and just abuts against the second module. It can also be other designed positions. Only the insertion depth during assembly needs to be controlled, and there are no excessive restrictions here.

[0052] S20: Control the limiting member 40 to move along the installation direction to the outside of the first housing 20.

[0053] For example, when the limiting member 40 is located above the first housing 20, the installation direction can be the downward direction of the Z direction of the optical axis. In this way, the limiting member 40 can be installed along the Z direction of the optical axis, which is convenient for reducing the installation difficulty of the limiting member 40.

[0054] S30: Fix and connect the limiting member 40 and the first housing 20 to prevent the first module from separating from the first housing 20.

[0055] In this way, during assembly, the lens 30 can be installed without disassembling the motor 10, making the assembly process of the lens 30 and the motor 10 relatively simple, which is beneficial to improving the assembly efficiency of the camera module. Moreover, the limiting member 40 is located outside the first housing 20 to facilitate reducing the setting difficulty of the limiting member 40.

[0056] It can be understood that the various parts of the motor 10 in the related art are not modularized, resulting in a relatively complex assembly process when the lens 30 is assembled with the motor 10. In this application, multiple mechanisms of the camera module are modularized. During assembly, the first module only needs to extend along the optical axis direction into the first opening 201 to complete the assembly with the second module. In this way, the assembly process of the camera module is simplified, which is beneficial to improving the assembly efficiency of the camera module 100.

[0057] According to the assembly method of the camera module in the embodiment of the present application, the first module and / or the second module can move in the Z direction of the optical axis to achieve their assembly, and the limiting member 40 can move along the installation direction to the outside of the first housing 20 to prevent the first module from separating from the first housing 20. In this way, the lens 30 and the motor 10 can be assembled without disassembling the motor 10, thus simplifying the assembly process of the camera module and being beneficial to improving the assembly efficiency of the camera module 100.

[0058] In some embodiments, the second module is provided with a guide member 50, such as Figure 2 shown, S10: Controlling the first module and / or the second module to move along the direction Z of the optical axis of the first module until the first module extends from the first opening 201 to a preset position within the first housing 20 includes:

[0059] S11: Controlling the first module and / or the second module to move along the direction Z of the optical axis until the first module is in guiding cooperation with the guide member 50;

[0060] S12: Controlling the first module and / or the second module to continue to move along the direction Z of the optical axis until the first module extends from the first opening 201 to a preset position within the first housing 20.

[0061] In this way, through the setting of the guide member 50, it is convenient to play a guiding role for the first module and / or the second module during the assembly process of the first module and the second module, that is, guiding first and then installing, thereby improving the assembly efficiency of the camera module.

[0062] In some embodiments, the first module is provided with a focusing magnet 304, and the second module is provided with a yoke 70, such as Figure 3 shown, S11: Controlling the first module and / or the second module to move along the direction Z of the optical axis until the first module is in guiding cooperation with the guide member 50 includes:

[0063] S101: Controlling the first module and / or the second module to move along the direction Z of the optical axis until the focusing magnet 304 and the yoke 70 reach a pre-fitting position;

[0064] S102: After the first module and / or the second module move to the pre-fitting position, controlling the first module and / or the second module to continue to move along the direction Z of the optical axis until the first module is in guiding cooperation with the guide member 50.

[0065] It can be understood that the pre-fitting position is generally a position where the yoke 70 on the second module is within the magnetic field range of the focusing magnet 304 of the first module, and it is the position of the first module when the focusing magnet 304 and the yoke 70 just sense the magnetic attraction between the two.

[0066] In this way, when installing the first module, even if the relative positions of the first module and the second module are misaligned, the magnetic attraction between the yoke 70 and the focusing magnet 304 can be used for adjustment, so that the side of the first module provided with the focusing magnet 304 can be accurately aligned with the side of the second module provided with the yoke 70, thereby preventing the first module from being installed in the wrong direction, that is, the yoke 70 can play an anti-fooling or positioning role in the installation of the first module. Thus, magnetic attraction first and then guiding is achieved, thereby improving the accuracy of guiding cooperation.

[0067] In some embodiments, such asFigure 14 and Figure 15 As shown in Figure 15 , the second module is provided with a rollable guiding ball 52, and the first module is provided with a guide rail 53 that cooperates with the guiding ball 52, or the second module is provided with a guide rail 53, and the first module is provided with a rollable guiding ball 52 that cooperates with the guide rail 53. Thus, the guiding ball 52 can be used to guide the first module, and when the first module moves in the Z direction along the optical axis, the guide rail 53 and the guiding ball 52 are in rolling friction. In this way, it is convenient to reduce the frictional force received by the first module, thereby reducing the energy consumption required for the movement of the first module.

[0068] As Figure 4 shown in Figure 4 , S11: Controlling the first module and / or the second module to move in the Z direction along the optical axis until the first module is in guiding cooperation with the guiding member 50 includes:

[0069] S111: Controlling the first module and / or the second module to move in the Z direction along the optical axis until the guiding ball 52 and the guide rail 53 are in guiding cooperation.

[0070] Thus, the guiding ball 52 and the guide rail 53 can be used to guide the first module, and when the first module moves in the Z direction along the optical axis, the guide rail 53 and the guiding ball 52 are in rolling friction. In this way, it is convenient to reduce the frictional force received by the first module. At the same time, the cooperation between the guiding ball 52 and the guide rail 53 is beneficial to improving the movement stability of the first module when moving in the Z direction along the optical axis.

[0071] In some embodiments, the guiding member 50 includes a guiding rod, and the first module is provided with a guiding groove 3021, or the guiding member 50 includes a guiding groove 3021, and the first module is provided with a guiding rod; As Figure 5 shown in Figure 5 , controlling the first module and / or the second module to move in the Z direction along the optical axis until the first module is in guiding cooperation with the guiding member 50 includes:

[0072] S112: Controlling the first module and / or the second module to move in the Z direction along the optical axis until the guiding groove 3021 and the guiding rod are in guiding cooperation.

[0073] In this way, by setting the guiding member 50 as a guiding rod, it is convenient to use the sliding cooperation between the guiding rod and the guiding groove 3021 to guide the first module during the assembly process of the first module, thereby improving the assembly efficiency of the camera module.

[0074] In some implementation manners, the guiding member 50 can be configured as a guide rail 53, a guiding column, a guiding groove 3021, or other structures that can achieve guiding, which are not limited herein.

[0075] In some embodiments, the guiding rod includes a metal guiding rod, and the metal guiding rod is detachably connected to the second module.

[0076] In this way, it is convenient to reduce the difficulty of loading and unloading the metal guide rod and is conducive to the later maintenance of the metal guide rod. In particular, the metal guide rod has high structural strength, which is conducive to improving the structural stability of the guide rod, and the outer peripheral wall of the metal guide rod is easily set as a smooth surface, thereby facilitating the reduction of the friction force received by the guide rod. Among them, the detachable connection method includes but is not limited to snap connection or bolt connection, etc.

[0077] In some embodiments, such as Figure 12 and Figure 13 shown, the guide rod includes a guide protrusion, and the guide protrusion is integrally injection-molded with the second module.

[0078] Thus, through the sliding fit between the guide protrusion and the guide groove, it is convenient to enhance the movement stability of the first module in the direction of the optical axis, and the guiding fit method between the guide protrusion and the guide groove is relatively simple, which is conducive to reducing the setting difficulty of the guiding fit.

[0079] In some embodiments, such as Figure 11 shown, the lens 30 includes a lens 301 and a bracket 302. The bracket 302 is a hollow structure, the lens 301 is arranged in the hollow structure, and an installation position 303 for arranging the focusing magnet 304 is provided on the outer side of the bracket 302.

[0080] It can be understood that the lens 30 of the present application is an integrated lens. Part of the bracket 302 is located in the first housing 20, that is, the limiting member 40 is used to limit the separation of the bracket 302 from the first housing 20 so as to realize the function of limiting the separation of the first module from the first housing 20. At the same time, the lens 301 is embedded in the bracket 302 and an installation position 303 for arranging the focusing magnet 304 is provided on the outer side of the bracket 302. In this way, when the focusing coil 13 is provided on the motor 10, the energization of the focusing coil 13 can drive the focusing magnet 304 to directly drive the lens 30 to move along the optical axis direction Z to achieve focusing. In this way, the camera module 100 of the present application does not need to be provided with a separate focusing carrier, so as to simplify its installation steps and is conducive to improving production efficiency. At the same time, the focusing magnet 304 can be directly installed on the lens 30, and further makes the arrangement of the lens 30 and the focusing magnet 304 more compact. In particular, the bracket 302 replaces the function of the lens barrel, so that the lens 30 of the present application can omit the lens barrel, thereby reducing the radial size of the lens 30 and facilitating the miniaturization design of the lens 30.

[0081] In some implementation manners, for example, when the lens 30 is an integrated lens, when the first module is located above the second module, the installation direction P can be the direction in which the optical axis direction Z is downward, and the first module can move along the installation direction P until it extends into the first housing 20. In this way, the first module can move downward from the upper direction of the first module until it extends into the first housing 20.

[0082] Among them, it should be noted that in order to ensure the smoothness of the optical path of the lens 30, a light passing hole for avoiding the optical path is provided on the base 11 of the second module. Generally, the radial dimension of a non-integrated lens is less than the aperture of the light passing hole. However, since the lens 30 of the first module in the present application is an integrated lens with the lens 301 embedded in the bracket 302, the radial dimension of the lens 30 in the present application is larger than that of a conventional non-integrated lens and will be greater than the size of the light passing hole, resulting in the lens 30 in the present application being unable to move upward from the lower side of the second module (i.e., in the direction of the optical axis Z) until it is assembled with the second module. Therefore, the first module in the present application can only move downward along the optical axis Z to achieve assembly with the second module.

[0083] In some implementation manners, the installation position 303 can be a groove or a planar area for bonding a magnet, which is not limited herein.

[0084] In some embodiments, as Figure 11 shown, the bracket 302 is provided with anti-collision protrusions 305. The anti-collision protrusions 305 are arranged at intervals around the lens 301, and the anti-collision protrusions 305 are adapted to abut against the limiting member 40 (such as Figure 7 and Figure 8 the limiting member 40 shown in). In this way, when the lens 30 performs autofocus, the anti-collision protrusions 305 can be used to abut against the limiting member 40 to limit the further movement of the lens 30, thereby playing a role in protecting the lens 30.

[0085] In some embodiments, as Figure 14 shown, the motor 10 includes: an anti-shake carrier 12. The anti-shake carrier 12 is sleeved on the lens 30, and the guiding member 50 is located between the anti-shake carrier 12 and the lens 30. In this way, the arrangement of the anti-shake carrier 12 can utilize the space outside the radial direction of the lens 30, thereby reducing the space occupied in the direction of the optical axis Z of the lens 30, and further facilitating the reduction of the size of the camera module 100 in the direction of the optical axis Z of the lens 30.

[0086] In some embodiments, the anti-shake carrier 12 is provided with a focusing coil 13. The focusing coil 13 is used to drive the focusing magnet 304 to drive the lens 30 to move along the optical axis direction, and the focusing coil 13 is arranged close to the guiding member 50.

[0087] In this way, the focusing coil 13 can be used to drive the focusing magnet 304 to drive the lens 30 to move along the optical axis direction to achieve focusing. In particular, the focusing coil 13 is arranged close to the guiding member 50. For example, the focusing coil 13 and the guiding member 50 are located on the same side of the anti-shake carrier 12, so that the focusing coil 13 and the guiding member 50 can be arranged on the same side, thereby facilitating the reduction of the setting difficulty.

[0088] In some embodiments, as Figure 8As shown, the yoke 70 is disposed on the anti-shake carrier 12 and on the side of the focusing coil 13 away from the focusing magnet 304. The yoke 70 is adapted to magnetically attract the focusing magnet 304.

[0089] It can be understood that to ensure the cooperation stability between the bracket 302 and the guide member 50, it is necessary to ensure a relatively close contact between the bracket 302 and the guide member 50. Therefore, in this application, a yoke 70 is disposed on the side of the focusing coil 13 away from the focusing magnet 304. For example, the yoke 70 can be a steel sheet. In this way, it is convenient to utilize the magnetic attraction between the yoke 70 and the focusing magnet 304, so that the bracket 302 has a tendency to move closer to the guide member 50, thereby ensuring a relatively close contact between the bracket 302 and the guide member 50, and further facilitating the improvement of the cooperation stability between the bracket 302 and the guide member 50. At the same time, the yoke 70 can reduce magnetic interference, ensuring that the focusing coil 13 can more stably drive the focusing magnet 304 to drive the lens 30 to move along the optical axis direction to achieve focusing.

[0090] At the same time, when installing the lens 30, due to the magnetic attraction between the yoke 70 and the focusing magnet 304 disposed on the lens 30, the side of the lens 30 where the focusing magnet 304 is disposed can be more accurately aligned with the yoke 70, thereby preventing the lens 30 from being installed in the wrong direction, that is, the yoke 70 can play a role in preventing misinstallation or positioning for the installation of the lens 30.

[0091] In some embodiments, as Figures 6-10 shown, the limiting member 40 includes a pressing piece. The pressing piece is provided with a second opening 41 for passing through the lens 30. The maximum aperture of the second opening 41 is smaller than the maximum aperture of the first opening 201.

[0092] In this way, it is convenient to utilize the second opening 41 with a smaller maximum aperture to limit the lens 30, thereby restricting the separation of the lens 30 from the first housing 20. Moreover, the inner wall of the second opening 41 is misaligned with the light passing area of the lens 30, so that the inner wall of the second opening 41 will not interfere with the optical path of the lens 30, facilitating the light transmission of the lens 30. In particular, constructing the limiting member 40 as a pressing piece provided with the second opening 41 makes the structure of the limiting member 40 relatively simple, which is beneficial to reducing the setting difficulty of the limiting member 40 and reducing the cost.

[0093] In some embodiments, the limiting member 40 includes at least one pressing piece. The at least one pressing piece is located outside the first housing 20 and shields a part of the first opening 20. The pressing piece is used to limit the separation of the first module and the first housing 20.

[0094] For example, the limiting member 40 may include a pressing piece disposed outside the first housing 20. The pressing piece shields a part of the first opening 201 and is adapted to abut against the first module. In this way, by partially shielding the first opening 201 with the pressing piece, it is equivalent to reducing the maximum aperture of the first opening 201, thereby achieving the effect of restricting the separation of the first module from the first housing 20.

[0095] Alternatively, the limiting member 40 includes two pressing pieces, both of which are disposed outside the first housing 20. Both pressing pieces shield a part of the first opening 201 and are adapted to abut against the first module, and the minimum distance between the two pressing pieces is less than the minimum aperture of the first opening 201. In this way, by partially shielding the first opening 201 with the two pressing pieces, it is equivalent to reducing the maximum aperture of the first opening 201, thereby achieving the effect of restricting the separation of the first module from the first housing 20. Among them, the two pressing pieces can be arranged symmetrically on both sides of the first opening 201.

[0096] In some embodiments, the motor 10 includes a base 11 and an anti-shake carrier 12. The base 11 is provided with a single-layer ball 112 that can roll. The anti-shake carrier 12 is used to mount the lens 30 and abuts against the single-layer ball 112. A damping member 60 is connected between the anti-shake carrier 12 and the base 11. The damping member 60 is used to apply a damping force to the anti-shake carrier 12 in the other direction when the anti-shake carrier 12 moves in one of the first direction X or the second direction Y. The first direction X and the second direction Y are both located in a plane perpendicular to the optical axis of the lens 30 and intersect.

[0097] It can be understood that the single-layer ball 112 in the present application may include a single ball or a ball group composed of a plurality of balls arranged in the horizontal direction. In this way, when the anti-shake carrier 12 moves relative to the base 11 to achieve the anti-shake function of the lens 30, the setting of the single-layer ball 112 can reduce the driving force output by the anti-shake coil 14 while satisfying the relative movement between the anti-shake carrier 12 and the base 110. At the same time, the anti-shake carrier 12 and the single-layer ball 112 are in rolling friction, so as to reduce the friction force suffered by the anti-shake carrier 12 during movement, thereby improving the load capacity of the anti-shake coil 14.

[0098] For example, when the anti-shake carrier 12 moves in the first direction X, if the anti-shake carrier 12 has a tendency to move in the second direction Y, the damping member 60 will apply a damping force to the anti-shake carrier 12 in the second direction Y, thereby preventing the anti-shake carrier 12 from moving in the second direction Y, and further ensuring that the anti-shake carrier 12 can move stably in the first direction X, thereby reducing the problem of the lens 30 being offset, and further improving the anti-shake effect of the motor 10.

[0099] Or when the anti-shake carrier 12 moves along the second direction Y, if the anti-shake carrier 12 has a tendency to move in the first direction X, the damping member 60 will apply a damping force to the anti-shake carrier 12 in the first direction X, thereby preventing the anti-shake carrier 12 from moving in the first direction X, and further ensuring that the anti-shake carrier 12 can move stably in the second direction Y, and further reducing the problem of the lens 30 shifting, and further improving the anti-shake effect of the motor 10.

[0100] Thus, the movement stability of the anti-shake carrier 12 when moving along the first direction X or the second direction Y can be improved, and further the problem of the lens 30 shifting can be reduced, and further the anti-shake effect of the motor 10 can be improved.

[0101] In some embodiments, the motor 10 further includes: an anti-shake coil 14, the anti-shake coil 14 is fixedly arranged on the base 11, a first anti-shake magnet 121 and a second anti-shake magnet 122 are arranged on the anti-shake carrier 12, the first anti-shake magnet 121 is arranged along the first direction X, the second anti-shake magnet 122 is arranged along the second direction Y, after the anti-shake coil 14 is energized, the first anti-shake magnet 121 drives the anti-shake carrier 12 to move along the first direction X under the action of the magnetic field generated by the anti-shake coil 14 to realize the anti-shake function of the lens 30 in the first direction X, or the second anti-shake magnet 122 drives the anti-shake carrier 12 to move along the second direction Y under the action of the magnetic field generated by the anti-shake coil 14 to realize the anti-shake function of the lens 30 in the second direction Y.

[0102] In some embodiments, the base 11 is provided with mounting grooves 111, there are a plurality of mounting grooves 111, the plurality of mounting grooves 111 are spaced apart from each other around the centroid of the base 11 in the circumferential direction of the base 11, and each mounting groove 111 is provided with a ball. In this way, the movement stability between the anti-shake carrier 12 and the base 11 can be enhanced by using a plurality of balls.

[0103] In some embodiments, as Figure 16 shown, the damping member 60 includes a body portion 61, a first elastic deformation portion 62 and a second elastic deformation portion 63, the body portion 61 is connected between the anti-shake carrier 12 and the base 11, the first elastic deformation portion 62 is adapted to elastically deform in the first direction X, and the second elastic deformation portion 63 is adapted to elastically deform in the second direction Y.

[0104] It can be understood that the first elastic deformation part 62 is adapted to apply a damping force in the first direction X, and the second elastic deformation part 63 is adapted to apply a damping force in the second direction Y. For example, when the anti-shake carrier 12 moves in the first direction X, if the driving force applied by the anti-shake coil 14 is greater than the elastic restoring force generated after the deformation of the first elastic deformation part 62, the anti-shake carrier 12 can move in the first direction X. If the anti-shake carrier 12 has a tendency to move in the second direction Y, it will cause the second elastic deformation part 63 to deform. At this time, the second elastic deformation part 63 will generate a damping force on the tendency of the anti-shake carrier 12 to move in the second direction Y under the action of its own elastic restoring force, thereby preventing the anti-shake carrier 12 from moving in the second direction Y, and further ensuring that the anti-shake carrier 12 can move stably in the first direction X, further reducing the problem of the lens 30 shifting, and further improving the anti-shake effect of the motor 10.

[0105] Or when the anti-shake carrier 12 moves in the second direction Y, if the driving force applied by the anti-shake coil 14 is greater than the elastic restoring force generated after the deformation of the second elastic deformation part 63, the anti-shake carrier 12 can move in the second direction Y. If the anti-shake carrier 12 has a tendency to move in the first direction X, it will cause the first elastic deformation part 62 to deform. At this time, the first elastic deformation part 62 will generate a damping force on the tendency of the anti-shake carrier 12 to move in the first direction X under the action of its own elastic restoring force, thereby preventing the anti-shake carrier 12 from moving in the first direction X, and further ensuring that the anti-shake carrier 12 can move stably in the second direction Y, further reducing the problem of the lens 30 shifting, and further improving the anti-shake effect of the motor 10.

[0106] In some embodiments, the motor 10 further includes: a focusing coil 13, and the focusing coil 13 is installed on the anti-shake carrier 12 and is used to drive the lens 30 to move in the direction Z of the optical axis.

[0107] It can be understood that in a scenario where the focusing magnet 304 is provided on the lens 30, after the focusing line coil is energized, the focusing coil 13 will generate a magnetic field. Under the action of the magnetic field, it will drive the focusing carrier part to drive the lens 301 part to move synchronously in the direction Z of the optical axis, thereby adjusting the focal length of the lens 30, and further realizing the autofocus of the camera module 100.

[0108] Among them, the damping member 60 is configured as an electrical connection piece, and the electrical connection piece is electrically connected between the focusing coil 13 and the electrical connection terminal on the base 11.

[0109] It can be understood that the focusing coil 13 needs to be electrically connected to a power supply device such as a battery through an electrical connection wire. In this application, by embedding a connection terminal in the base 11 and using the damping member 60 as the electrical connection structure between the focusing coil 13 and the connection terminal, the damping member 60 can play a role in electrically connecting the focusing coil 13 and the connection terminal while assisting in realizing the anti-shake function.

[0110] In this way, it is convenient to use the damping member 60 in the anti-shake function to achieve the electrical connection between the focusing coil 13 and the connection terminal, thereby increasing the function of the damping member 60. At the same time, there is no need to separately set the electrical connection structure between the focusing coil 13 and the connection terminal, which is convenient for reducing the number of its structures, thereby facilitating the simplification of the structural setting of the camera module 100. And due to the reduction of the number of structures, it is convenient to reduce the volume of the camera module 100, which is conducive to realizing the miniaturized design of the camera module 100.
