[0001] This application belongs to the technical field of electronic products, and particularly relates to an imaging module and an electronic device. Background Art

[0002] With the development of the electronic product industry, the photographing and imaging functions of electronic devices have increasingly become the focus of attention. In the prior art, an electronic device is internally provided with an imaging module, and the imaging module includes a photosensitive chip and a lens assembly. By driving the overall or partial movement of the lens assembly to approach or move away from the photosensitive chip, focusing is achieved, thereby improving the photographing and imaging effects. However, in order to accurately focus, the moving distance of the lens assembly is large, resulting in a slow focusing speed. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide an imaging module and an electronic device, which can solve the problem of slow focusing speed of the imaging module of the electronic device in the related art.

[0004] In a first aspect, the embodiments of this application provide an imaging module, including:

[0005] A first lens, a second lens, and a photosensitive chip, the first lens, the second lens, and the photosensitive chip are arranged at intervals along the optical axis direction of the imaging module,

[0006] One of the first lens and the second lens is a first moving member, and the other is a second moving member; alternatively, one of the first lens and the photosensitive chip is a first moving member, and the other is a second moving member; alternatively, one of the second lens and the photosensitive chip is a first moving member, and the other is a second moving member;

[0007] A connecting component, the connecting component is respectively connected to the first moving member and the second moving member, so that the moving directions of the first moving member and the second moving member are opposite;

[0008] When the first moving member moves in a first direction, the second moving member moves in the reverse direction of the first direction, and the first direction is parallel to the optical axis direction.

[0009] In a second aspect, the embodiments of this application further provide an electronic device, including a housing and an imaging module, and the imaging module is arranged in the housing.

[0010] In the embodiment of the present application, a connection component is added to the camera module to connect the first moving member and the second moving member. Then, under the action of the connection component, when the first moving member moves, the second moving member moves in the opposite direction. That is to say, two of the first lens, the second lens and the photosensitive chip approach or move away from each other. When the first moving member and the second moving member are the first lens and the second lens respectively, while adjusting the distance between the first lens and the photosensitive chip and the distance between the second lens and the photosensitive chip, then, compared with only one lens moving for focusing, the moving amount of the first lens or the second lens for achieving focusing is reduced, and the moving time is shortened, which is beneficial to improving the focusing speed and focusing efficiency; when the first moving member is the first lens or the second lens and the second moving member is the photosensitive chip, the distance between the first lens or the second lens and the photosensitive chip quickly decreases or increases. To achieve focusing, the moving amount of the first lens or the second lens is reduced, which is beneficial to improving the focusing speed and focusing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0029] The camera module and electronic device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0030] Please refer to Figures 1 - 5 , the camera module disclosed in the embodiments of the present application includes a first lens 100, a second lens 200, an image sensor chip 300, a driving member 400, and a connecting component. Among them, the first lens 100, the second lens 200, and the image sensor chip 300 are arranged at intervals along the optical axis a direction of the camera module. External light passes through the first lens 100 and the second lens 200 in sequence and forms an image on the image sensor chip 300. The image sensor chip 300 receives the light and converts it into an electrical signal, and further processes the electrical signal through the device to achieve image presentation.

[0031] Optionally, the photosensitive chip 300 can be a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor); the number of the first lenses 100 can be one or more, and the number of the second lenses 200 can also be one or more. The embodiments of the present application do not limit the number of the first lenses 100 and the second lenses 200.

[0032] One of the first lens 100 and the second lens 200 is a first moving member, and the other is a second moving member. Specifically, the first lens 100 is the first moving member and the second lens 200 is the second moving member, or the first lens 100 is the second moving member and the second lens 200 is the first moving member. Or, one of the first lens 100 and the photosensitive chip 300 is a first moving member, and the other is a second moving member. Specifically, the first lens 100 is the first moving member and the photosensitive chip 300 is the second moving member, or the first lens 100 is the second moving member and the photosensitive chip 300 is the first moving member. Or, one of the second lens 200 and the photosensitive chip 300 is a first moving member, and the other is a second moving member. Specifically, the second lens 200 is the first moving member and the photosensitive chip 300 is the second moving member, or the second lens 200 is the second moving member and the photosensitive chip is the first moving member. That is to say, any two of the first lens 100, the second lens 200 and the photosensitive chip 300 are respectively the first moving member and the second moving member.

[0033] The connecting assembly is respectively connected to the first moving member and the second moving member. Under the connection action of the connecting assembly, the moving directions of the first moving member and the second moving member are opposite.

[0034] Specifically, when the first moving member moves along the first direction, the second moving member moves along the reverse direction of the first direction, and the first direction is parallel to the direction of the optical axis a. The first direction is Figures 1 - 2 and Figure 5 the direction indicated by the arrow in. The first direction can be the direction in which the first lens 100, the second lens 200 and the photosensitive chip 300 are arranged, or the direction in which the photosensitive chip, the second lens 200 and the first lens 100 are arranged. Optionally, the connecting assembly can only play a transmission role, that is, when the first connecting member moves along the first direction, the connecting assembly drives the second moving member to move along the reverse direction of the first direction; or, the connecting assembly plays a driving role, and the connecting assembly can drive the first moving member and the second moving member to move in opposite directions at the same time.

[0035] In an embodiment of the present application, a connection component is added to the camera module to connect the first moving member and the second moving member. Then, under the action of the connection component, when the first moving member moves, the second moving member moves in the opposite direction. That is to say, two of the first lens 100, the second lens 200, and the photosensitive chip 300 move simultaneously to approach or move away from each other.

[0036] When the first moving member and the second moving member are the first lens 100 and the second lens 200 respectively, the distance between the first lens 100 and the photosensitive chip 300 and the distance between the second lens 200 and the photosensitive chip 300 are adjusted simultaneously. Then, compared with only one lens moving for focusing, the moving amount of the first lens 100 or the second lens 200 for achieving focusing is reduced, and the moving time is shortened, which is beneficial to improving the focusing speed and focusing efficiency; when the first moving member is the first lens 100 or the second lens 200, and the second moving member is the photosensitive chip 300, the distance between the first lens 100 or the second lens 200 and the photosensitive chip 300 decreases or increases rapidly. To achieve focusing, the moving amount of the first lens 100 or the second lens 200 is reduced, which is beneficial to improving the focusing speed and focusing efficiency.

[0037] Optionally, when the first lens 100 has a greater impact on the optical system of the camera module, the position of the first lens 100 is fixed, and the first moving member and the second moving member are the second lens 200 and the photosensitive chip 300 respectively; when the second lens 200 has a greater impact on the optical system of the camera module, the position of the second lens 200 is fixed, and the first moving member and the second moving member are the first lens 100 and the photosensitive chip 300 respectively, to ensure the stability of the camera module.

[0038] In an optional embodiment, the connection component can be a driving component. That is to say, the connection component has the function of driving the first moving member and the second moving member to move. Specifically, the driving component includes a first driving member and a second driving member. The first driving member is connected to the first moving member, and the second driving member is connected to the second moving member. When the first driving member drives the first moving member to move in the first direction, the second driving member drives the second moving member to move in the opposite direction of the first direction.

[0039] Optionally, the first driving member and the second driving member can be driving members such as linear modules that can generate linear displacement; the first driving member can be a first deformation element, and the second driving member can be a second deformation element. Further optionally, the deformation element can be an electro-induced deformation element such as a shape memory alloy. When the first deformation element and the second deformation element are energized, the first deformation element and the second deformation element both generate deformations, thereby driving the first moving member and the second moving member to approach or move away from each other.

[0040] In another embodiment, the connecting component is a transmission component 500, and the first moving member and the second moving member are drivingly connected through the transmission component 500. When the first moving member moves in the first direction, the first moving member drives the second moving member to move in the opposite direction of the first direction through the transmission component 500. That is to say, the connecting component does not have the power to drive the first moving member or the second moving member to move, and the connecting component only plays a role of driving connection.

[0041] With this embodiment, when the first moving member is driven to move in the first direction, relying on the driving connection of the transmission component 500, the second moving member can be directly driven to move in the opposite direction. In this way, it is not necessary to separately drive the first moving member and the second moving member, which is beneficial to saving driving power and simplifying the driving structure.

[0042] In an alternative embodiment, the transmission component 500 includes a rotating member 511, a first transmission member 512, and a second transmission member 513. The rotating member 511 is rotatably arranged. Optionally, when the imaging module is applied to an electronic device, the rotating member 511 is rotatably arranged on the housing of the electronic device, and the rotation of the rotating member 511 is realized by fixing the position of the rotating member 511 relative to the housing. The first transmission member 512 is connected to the first moving member, the second transmission member 513 is connected to the second moving member, and the rotating member 511 is drivingly connected to the first transmission member 512 and the second transmission member 513 respectively. Optionally, the first transmission member 512 can be directly fixedly connected to the first moving member by welding, bonding or other means, and the second transmission member 513 can also be directly fixedly connected to the second moving member by welding, bonding or other means.

[0043] When the first moving member drives the first transmission member 512 to move in the first direction, the rotating member 521 rotates and drives the second transmission member 513 to move in the opposite direction of the first direction, and then the second transmission member 513 drives the second moving member to move in the opposite direction of the first direction.

[0044] The embodiments of the present application do not limit the specific structures of the rotating member 511, the first transmission member 512, and the second transmission member 513. It is only necessary to be able to convert the linear movement power into rotational power by relying on the rotating member 511 and the first transmission member 512, and further convert the rotational power into linear movement power in the opposite direction by relying on the rotating member 511 and the second transmission member 513.

[0045] This embodiment avoids an overly complex transmission structure through the conversion process of movement-rotation-movement, realizes that the first transmission member 512 stably drives the second transmission member 513 to move during the movement, and is beneficial to the first moving member and the second moving member to stably move in opposite directions.

[0046] Of course, in other embodiments, the transmission assembly may also adopt other mating structures other than the rotating member 511, the first transmission member 512, and the second transmission member 513, as long as the first moving member and the second moving member can move in opposite directions.

[0047] In an alternative embodiment, referring to Figure 1 and Figure 2 as shown, the rotating member 511 is a gear, the first transmission member 512 is a first transmission guide rail, and the second transmission member 513 is a second transmission guide rail. The first transmission guide rail and the second transmission guide rail extend along the direction of the optical axis a respectively. The gear is rotatably arranged between the first transmission guide rail and the second transmission guide rail, that is to say, the gear can rotate in place. Optionally, the housing of the electronic device may be provided with support columns, and the gear is sleeved outside the support columns, and the gear can rotate relative to the support columns.

[0048] The gear is in transmission cooperation with the first transmission guide rail and the second transmission guide rail respectively. Specifically, a plurality of first engaging teeth 512a are arranged at intervals along the direction of the optical axis a on the first transmission guide rail, and a plurality of second engaging teeth 513a are arranged at intervals along the direction where the optical axis a is located on the second transmission guide rail. The first engaging teeth 512a and the second engaging teeth 513a both face the gear, and the first engaging teeth 512a and the second engaging teeth 513a are respectively engaged with the gear.

[0049] In this way, when the first transmission guide rail moves, the rotation of the gear is realized by relying on the meshing action between the first engaging teeth 512a and the gear. When the gear rotates, the second transmission guide rail is driven to move in the reverse direction by relying on the second engaging teeth 513a; similarly, when the second transmission guide rail moves, the rotation of the gear is realized by relying on the meshing action between the second engaging teeth 513a and the gear. When the gear rotates, the first transmission guide rail is driven to move in the reverse direction by relying on the first engaging teeth 512a.

[0050] Optionally, both the first transmission guide rail and the second transmission guide rail can be racks.

[0051] With this embodiment, when the first moving member moves, the first moving member drives the first transmission guide rail 511 to move, and the gear is relied on to drive the second transmission guide rail to move in the reverse direction, thereby driving the second moving member to move in the reverse direction, so that two of the first lens 100, the second lens 200, and the photosensitive chip 300 move simultaneously and in opposite directions. Directly using the gear as the rotating member 511 eliminates the need to set up a complex transmission structure for the rotating member 511. Moreover, the tooth meshing method makes the moving speed stable and balanced, avoiding the situation of picture jitter in the imaging module.

[0052] In another embodiment, referring to Figure 3 and Figure 4As shown, the rotating member 511 is a rotating rod, which is rotatably arranged around its own axis. The rotating rod is provided with a spiral groove 511a. Both the first transmission member 512 and the second transmission member 513 extend into the spiral groove 511a, and both the first transmission member 512 and the second transmission member 513 can move relative to the rotating rod along the extending direction of the spiral groove 511a. Specifically, when the first transmission member 512 moves, the first transmission member 512 acts on the groove wall surface of the spiral groove 511a, and the first transmission member 512 can only move along the extending direction of the spiral groove 511a. Therefore, the rotating rod can be driven to rotate in place. During the rotation of the rotating rod, the groove wall surface of the spiral groove 511a acts on the second transmission member 513 again, so that the second transmission member 513 also moves along the extending direction of the spiral groove 511a, realizing the reverse movement of the second transmission member 513.

[0053] By adopting this embodiment, only by opening a spiral groove 511a on the rotating member 511, the cooperation between the rotating member 511 and the first transmission member 512 and the cooperation between the rotating member 511 and the second transmission member 513 can be realized, which is beneficial to simplifying the structure of the rotating member 511.

[0054] In an alternative embodiment, the rotating rod is provided with a spiral blade 5111, and the spiral blade 5111 forms the spiral groove 511a. Optionally, the surfaces of both the first transmission member 512 and the second transmission member 513 can be matched with the surface of the spiral blade 5111.

[0055] By adopting this embodiment, the spiral groove 511a is directly formed by the spiral blade 5111, and there is no need to separately open a spiral groove 511a on the rotating member 511, which is beneficial to simplifying the process; moreover, the depth of the spiral groove 511a formed by the spiral blade 5111 is relatively large, which is more conducive to the stable cooperation between the first transmission member 512 and the second transmission member 513 and the rotating member 511 respectively.

[0056] In another embodiment, the rotating rod is provided with a first thread, and the first thread forms the spiral groove 511a. Both the first transmission member 512 and the second transmission member 513 are provided with a second thread, and the first thread is matched with the second thread. Specifically, both the first thread and the second thread include multiple turns of thread protrusions. The spiral groove 511a is formed between two adjacent turns of thread protrusions of the rotating rod. The thread protrusions of the second thread extend into the spiral groove 511a, which is similar to the structure of the cooperation between the internal thread and the external thread in the prior art. Optionally, the rotating rod, the first transmission member 512 and the second transmission member 513 can all adopt threaded fasteners with threads such as bolts and screws, and there is no need to separately set the first thread and the second thread.

[0057] In this embodiment, the rotating rod is in threaded engagement with the first transmission member 512 and the second transmission member 513 to achieve a transmission connection, which is beneficial to increasing the transmission cooperation area between the rotating rod and the first transmission member 512, and increasing the transmission cooperation area between the rotating rod and the second transmission member 513, and is more conducive to the stable movement of the first transmission member 512 and the second transmission member 513.

[0058] Of course, the rotating rod can also form the spiral groove 511a in other ways, and the formation method of the spiral groove 511a is not limited to the above embodiment.

[0059] In a further embodiment, referring to Figure 1 , Figures 3 - 5 As shown, the first moving member is the first lens 100, the second moving member is the second lens 200, and the transmission assembly 500 further includes a first connecting member 514 and a second connecting member 515. The first transmission member 512 is connected to the first lens 100 through the first connecting member 514. Optionally, the first connecting member 514 and the first transmission member 512, and the first connecting member 514 and the first lens 100 can be connected by welding, bonding or other means; the second transmission member 513 is connected to the second lens 200 through the second connecting member 515. Optionally, the second connecting member 515 and the second transmission member 513, and the second connecting member 515 and the second lens 200 can be connected by welding, bonding or other means.

[0060] In this way, the first connecting member 514 and the second connecting member 515 are provided to avoid the problem that the first transmission member 512 is not convenient to be directly connected to the first lens 100, and avoid the problem that the second transmission member 513 is not convenient to be directly connected to the second lens 200.

[0061] In the solution of the present application, the imaging module further includes a driving member 400, and the driving member 400 is connected to the first moving member, and the driving member 400 can drive the first moving member to move in the first direction. That is to say, the driving member 400 can be connected to the first lens 100, the driving member 400 can also be connected to the second lens 200, or can be connected to the photosensitive chip 300. Optionally, the driving member 400 can be a driving motor, a linear module or other driving members 400 that can generate a linear driving force, and the specific structure of the driving member 400 is not limited in the embodiments of the present application.

[0062] In this embodiment, by directly driving the first moving member by the driving member 400, it is beneficial for the lens to move relative to the photosensitive chip 300 quickly to achieve focusing and improve the focusing efficiency.

[0063] Of course, in other embodiments, the imaging module may not be provided with the driving member 400, and the first moving member can be driven to move in the first direction by an external force or an external driving mechanism.

[0064] In an alternative embodiment, with reference to Figure 6 As shown, the driving member 400 includes an energized coil 410 and a magnetic member 420 which are oppositely arranged. One of the energized coil 410 and the magnetic member 420 is connected to the first moving member. When the energized coil 410 is energized, one of the energized coil 410 and the magnetic member 420 drives the first moving member to move relative to the other of the energized coil 410 and the magnetic member 420 in the first direction. Specifically, when the energized coil 410 is energized, the energized coil 410 generates an induced magnetic field, and the magnetic member 420 is affected by the Lorentz force in the induced magnetic field, and the magnetic member 420 moves relative to the energized coil 410.

[0065] Optionally, the second lens 200 is the first moving member, and the energized coil 410 and the second lens 200 can be connected by welding, bonding or the like. The position of the magnetic member 420 is fixed. Further optionally, when the imaging module is applied to an electronic device, the magnetic member 420 can be fixedly connected to the housing of the electronic device to fix its position; or, the magnetic member 420 and the second lens 200 are connected by welding, bonding or the like, and the position of the energized coil 410 is fixed. Further optionally, when the imaging module is applied to an electronic device, the energized coil 410 can be fixedly connected to the housing of the electronic device to fix its position. Of course, the energized coil 410 or the magnetic member 420 can also be connected to the first lens 100 or the photosensitive chip 300.

[0066] Compared with using a driving motor with a complex structure as the driving member 400, the structures of the magnetic member 420 and the energized coil 410 are simple, which is beneficial to reducing the occupied space of the driving member 400 and reducing the volume of the imaging module.

[0067] In this embodiment, the magnetic member 420 is connected to the second lens 200, and the position of the energized coil 410 is fixed. By passing currents in different directions through the energized coil 410, the magnetic member 420 can drive the second lens 200 to move in different directions along the optical axis a.

[0068] In another embodiment, the driving member 400 may include an electro-deformable element. The electro-deformable element may be a bimetallic strip, a piezoelectric sheet, etc. The electro-deformable element is connected to the first moving member, that is, the electro-deformable element can be connected to the first lens 100, can also be connected to the second lens 200, and can also be connected to the photosensitive chip 300. When the electro-deformable element is energized, the electro-deformable element deforms and drives the first moving member to move in the first direction.

[0069] Optionally, when an electric current of different directions is applied to the electro-deformation element, the directions of deformation generated by the electro-deformation element are opposite, and the electro-deformation element drives the first moving member to move in different directions along the optical axis a. Alternatively, when the electro-deformation element is energized, the electro-deformation element generates deformation, and the electro-deformation element drives the first moving member to move in the first direction; when the electro-deformation element is de-energized, the electro-deformation element recovers the deformation, and the electro-deformation element drives the first moving member to move in the reverse direction of the first direction. Further optionally, the driving member 400 may further include an elastic member. One end of the elastic member is connected to the first moving member, and the other end of the elastic member is connected to the second moving member. When the electro-deformation element drives the first moving member to move in the first direction, the elastic member generates elastic deformation. When the electro-deformation element is de-energized, the elastic member recovers the elastic deformation and drives the electro-deformation element to recover the deformation.

[0070] Compared with using a driving motor with a complex structure as the driving member 400, the structure of the electro-deformation element is simple, which is beneficial to reducing the occupied space of the driving member 400 and the volume of the camera module.

[0071] In an optional embodiment, the first lens 100 is the first moving member, the second lens 200 is the second moving member, and the position of the photosensitive chip 300 is fixed, and the position of the photosensitive chip 300 is not affected by the movement of the second lens 200.

[0072] In another embodiment, refer to Figure 5 As shown, the first lens 100 is the first moving member, the second lens 200 or the photosensitive chip 300 is the second moving member. The second lens 200 is fixedly connected to the photosensitive chip 300, and the photosensitive chip 300 can move along the direction of the optical axis a with the second lens 200. Optionally, the second lens 200 and the photosensitive chip 300 can be encapsulated into the same module, so as to realize the relative fixation of the second lens 200 and the photosensitive chip 300; or, the second lens 200 and the photosensitive chip 300 are connected by welding, bonding and other methods to realize the relative fixation of the two. Of course, the method of realizing the fixed connection between the second lens 200 and the photosensitive chip 300 is not limited to this.

[0073] Adopting this embodiment, when the first moving member and the second moving member move simultaneously, the position of the second lens 200 relative to the photosensitive chip 300 is fixed, and only the position of the first lens 100 relative to the photosensitive chip 300 changes, which is beneficial to increasing the tolerance of the optical system of the camera module and improving the stability of the camera module.
