[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. The term "multiple" refers to two or more, unless otherwise explicitly limited. Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those skilled in the art. In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0041] Auto-focusing refers to the ability to automatically adjust the focal length of the lens to keep the image clear according to the distance between the measured object and the vision system. It is based on the principle of light reflection of objects, the sensor on the camera receives the reflected light, which is processed by a computer and focused by a focusing device. In the related art, when the lens assembly in the electronic device is automatically focused, the lens moves along the optical axis. Due to the limited space of the electronic device, the lens assembly has a short stroke during automatic focusing.

[0042] This disclosure first provides an exemplary embodiment of a lens assembly, such as... Figure 1 and Figure 2 As shown, the lens assembly includes: a bracket 10, a first carrier 20, a second carrier 30, and a drive member 50. The first carrier 20 is disposed on the bracket 10 and is movable relative to the bracket 10 in a first direction. The second carrier 30 is used to support the lens, is disposed on the first carrier 20, and is movable relative to the first carrier 20 in the first direction. The drive member 50 includes a first drive part, a second drive part, and a third drive part. The first drive part is disposed on the bracket 10, the second drive part is disposed on the first carrier 20, and the third drive part is disposed on the second carrier 30. The first drive part and the second drive part cooperate to drive the first carrier 20 to move relative to the bracket 10 in the first direction, and the second drive part and the third drive part cooperate to drive the second carrier 30 to move relative to the first carrier 20 in the first direction.

[0043] The lens assembly provided in this embodiment includes a bracket 10, a first carrier 20, a second carrier 30, and a driving member 50. The first carrier 20 can move relative to the bracket 10 along a first direction, and the second carrier 30 can move relative to the first carrier 20 along the first direction. The driving member 50 drives the first carrier 20 to move relative to the bracket 10 along the first direction and drives the second carrier 30 to move relative to the first carrier 20 along the first direction, thereby realizing multi-level movement of the lens assembly, which can improve the formation of autofocus and improve the imaging quality of the lens assembly.

[0044] The lens assembly provided in this disclosure will be described below through several embodiments:

[0045] In some embodiments of this disclosure, the bracket 10 is relatively fixed in position within the electronic device 100. For example, the bracket 10 can be fixedly connected to the motherboard or mid-frame of the electronic device 100. The bracket 10 is used to support the first carrier 20 and the second carrier 30. The bracket 10 is provided with a first hole 101 along a first direction, and the first carrier 20 is disposed in the first hole 101 and can slide along the first hole 101. The first carrier 20 is provided with a second hole 201 along the first direction, and the second carrier 30 is disposed in the second hole 201 and can slide along the second hole 201.

[0046] like Figure 4 As shown, a first hole 101 is provided on the bracket 10, and the first hole 101 is arranged along a first direction. The first hole 101 can be a through hole penetrating the bracket 10 along the first direction, and the sidewall of the first hole 101 is parallel to the first direction. The first carrier 20 is disposed in the first hole 101, and the first carrier 20 moves along the sidewall of the first hole 101, that is, the sidewall of the first hole 101 guides the movement of the first carrier 20.

[0047] To prevent the first carrier 20 from rotating within the first hole 101, the bracket 10 can be configured as an anti-torsion structure. For example, the first hole 101 on the bracket 10 can be a rectangular hole, or a guide structure extending in a first direction can be provided on the side wall of the first hole 101. For example, a guide groove or guide protrusion extending in a first direction can be provided on the side wall of the first hole 101.

[0048] For example, the support 10 can be in the form of a cuboid or approximately cuboid, and the first hole 101 on the support 10 is a rectangular or approximately rectangular through hole. The sidewall of the first hole 101 is perpendicular to the end face of the support 10, thereby enabling the first carrier 20 to move in a first direction perpendicular to the end face of the support 10.

[0049] like Figure 5 As shown, the first carrier 20 can move relative to the support 10 along a first direction, thereby enabling the lens assembly to achieve a first-stage movement. A second hole 201 is provided on the first carrier 20, penetrating through it in the first direction. The second carrier 30 is disposed within the second hole 201. The sidewall of the second hole 201 is parallel to the first direction, and the second carrier 30 moves along the sidewall of the second hole 201; that is, the sidewall of the second hole 201 guides the movement of the second carrier 30. The second carrier 30 can move within the second hole 201 along the first direction, thereby achieving a second-stage movement of the lens assembly.

[0050] To prevent the second carrier 30 from rotating within the second hole 201, the first carrier 20 can be configured as an anti-torsion structure. For example, the second hole 201 on the first carrier 20 can be a rectangular hole, or a guide structure extending in a first direction can be provided on the side wall of the second hole 201. For example, a guide groove or guide protrusion extending in the first direction can be provided on the side wall of the second hole 201.

[0051] For example, the first carrier 20 may have a cuboid or approximately cuboid structure, and the second hole 201 on the first carrier 20 is a rectangular or approximately rectangular through hole. The sidewall of the second hole 201 is perpendicular to the end face of the first carrier 20, thereby enabling the second carrier 30 to move in a first direction perpendicular to the end face of the first carrier 20.

[0052] The lens assembly has a first state and a second state. When the lens assembly is in the first state, the first carrier 20 and the second carrier 30 are embedded in the bracket 10. When the lens assembly is in the second state, the first carrier 20 protrudes from the bracket 10 along the first direction, and the second carrier 30 protrudes from the first carrier 20 along the first direction.

[0053] In the first state, the first carrier 20 is received in the holder 10, and the second carrier 30 is received in the first carrier 20. In the second state, the first carrier 20 is extended from the holder 10, and the second carrier 30 is extended from the first carrier 20.

[0054] In some embodiments, the holder 10, the first carrier 20 and the second carrier 30 have the same size in the first direction. In the first state, the side of the first carrier 20 close to the light-incoming side is flush with the side of the holder 10 close to the light-incoming side, and the side of the second carrier 30 close to the light-incoming side is flush with the side of the first carrier 20 close to the light-incoming side. The side of the first carrier 20 away from the light-incoming side is flush with the side of the holder 10 away from the light-incoming side, and the side of the second carrier 30 away from the light-incoming side is flush with the side of the first carrier 20 away from the light-incoming side.

[0055] In the first state, the first carrier 20 and the second carrier 30 are embedded in the holder 10, i.e., in the first state, the first carrier 20 and the second carrier 30 do not protrude from the holder 10 in the first direction, thereby saving space in the electronic device 100 and increasing the maximum travel of the autofocus as much as possible in the limited space.

[0056] As shown in FIG. 1, the lens assembly 100 includes a holder 10, a first carrier 20 and a second carrier 30. Figure 6 The lens can include one or more optical lenses. In the lens assembly, the first carrier 20 and the second carrier 30 can drive the entire lens to move in the first direction. Alternatively, the first carrier 20 and the second carrier 30 can drive part of the lenses to move, which is not limited in the embodiments of the present disclosure.

[0057] In some embodiments, the lens assembly further includes a connecting spring 40, as shown in FIG. 2. Figure 3 The connecting spring 40 includes a first deformation part 401 and a second deformation part 402. The first deformation part 401 connects the holder 10 and the first carrier 20, and the second deformation part 402 connects the first carrier 20 and the second carrier 30.

[0058] In the first state, the first deformation part 401 and the second deformation part 402 are not deformed. In the second state, the first deformation part 401 and the second deformation part 402 are deformed. The first deformation part 401 has elasticity, and generates an elastic force after being deformed, which is used for resetting the first carrier 20. The second deformation part 402 has elasticity, and generates an elastic force after being deformed, which is used for resetting the second carrier 30.

[0059] Optionally, the connecting spring 40 can further comprise a first connecting portion 403, a second connecting portion 404 and a third connecting portion 405. The first connecting portion 403 is connected with the first deformation portion 401 and fixed to the support 10. The second connecting portion 404 is connected with the second deformation portion 402 and fixed to the second carrier 30. The third connecting portion 405 is connected with the first deformation portion 401 and the second deformation portion 402 respectively and fixed to the first carrier 20.

[0060] The first deformation portion 401 is connected with the first connecting portion 403 and the second connecting portion 404 respectively. The first deformation portion 401 can be a sheet structure or a spring. When the first deformation portion 401 is a sheet structure, the first deformation portion 401 can be provided along a preset folding line. The folding line shaped first deformation portion 401 can be deformed when the first carrier 20 moves relative to the support 10, and the deformation is to make the first deformation portion 401 have a straightening trend. The connecting spring 40 can be an integral structure, for example, the connecting spring 40 can be formed by stamping or cutting.

[0061] The second deformation portion 402 is connected with the third connecting portion 405 and the second connecting portion 404 respectively. The second deformation portion 402 can be a sheet structure or a spring. When the second deformation portion 402 is a sheet structure, the second deformation portion 402 can be provided along a preset folding line. The folding line shaped second deformation portion 402 can be deformed when the second carrier 30 moves relative to the first carrier 20, and the deformation is to make the second deformation portion 402 have a straightening trend.

[0062] The first connecting portion 403 can be connected to the support 10 by riveting, welding or bolt connection, etc. The second connecting portion 404 can be connected to the second carrier 30 by riveting, welding or bolt connection, etc. The third connecting portion 405 can be connected to the first carrier 20 by riveting, welding or bolt connection, etc.

[0063] In order to avoid the support 10 interfering with the deformation of the first deformation portion 401, the first carrier 20 is provided with a first avoiding gap 22 for avoiding the first deformation portion 401 when the first carrier 20 moves in the first direction.

[0064] The first avoiding gap 22 is provided in the projection area of the first deformation portion 401 in the first direction on the first carrier 20. The area of the first avoiding gap 22 is greater than the area of the projection area of the first deformation portion 401 in the first direction on the first carrier 20. The depth of the first avoiding gap 22 is greater than or equal to the stroke of the first carrier 20, and the depth of the first avoiding gap 22 is the size of the first avoiding gap 22 in the first direction.

[0065] In order to avoid the second carrier 30 interfering with the deformation of the second deformation part 402, a second avoiding gap 32 is arranged on the second carrier 30, and the second avoiding gap 32 is used to avoid the second deformation part 402 when the second carrier 30 moves in the first direction.

[0066] The second avoiding gap 32 is arranged in the projection area of the second deformation part 402 in the first direction on the second carrier 30. The area of the second avoiding gap 32 is greater than the area of the projection area of the second deformation part 402 in the first direction on the second carrier 30. The depth of the second avoiding gap 32 is greater than or equal to the stroke of the second carrier 30, and the depth of the second avoiding gap 32 is the size of the second avoiding gap 32 in the first direction.

[0067] In some embodiments, the bracket 10 is provided with a first connecting spring 41 on the side close to the light entrance side of the lens assembly, and a second connecting spring 42 on the side away from the light entrance side of the lens assembly. By arranging the first connecting spring 41 and the second connecting spring 42 on the two sides of the bracket 10 respectively, the reset spring force of the first carrier 20 and the second carrier 30 can be improved, and the stability of the movement of the first carrier 20 and the second carrier 30 can be improved.

[0068] It should be noted that the first connecting spring 41 and the second connecting spring 42 are both the connecting spring 40 described above. That is, the first connecting spring 41 and the second connecting spring 42 have the same structure, and the first connecting spring 41 and the second connecting spring 42 have the same connection mode. In this way, the uniformity of the force received by the first carrier 20 and the second carrier 30 during movement can be improved, and the stability of the autofocus can be improved. Of course, in some embodiments, the structure of the first connecting spring 40 and the second connecting spring 42 can be different, and the embodiments of the present disclosure are not limited thereto.

In order to improve the balance of the movement of the first carrier 20, the magnet 53 can be arranged on the opposite sides of the first carrier 20, respectively.

[0072] The third mounting portion 31 is provided on the second carrier 30, and the second coil 52 is mounted on the third mounting portion 31.

In order to improve the balance of the movement of the second carrier 30, the second coil 52 can be arranged on the opposite sides of the second carrier 30, respectively.

[0073] In some embodiments, the driving member 50 can further include a flexible circuit board 54, and the flexible circuit board 54 is connected to the first coil 51 and the second coil 52, respectively.
