Description

[Technical field]

[0001] The present disclosure relates to the technical field of electronic devices, and in particular to a camera module and an electronic device. [Background technology]

[0002] Cameras are an important part of electronic devices (such as mobile phones, tablet computers, camera devices, surveillance devices, drones, etc.) that acquire images. For aesthetics and portability, there is a demand for the development of miniaturization of electronic devices, and there is also a demand for cameras with the same focus adjustment range to become smaller and smaller.

[0003] Liquid lenses are lightweight and can meet the needs of miniaturization of electronic devices, and therefore are increasingly being applied to electronic devices (e.g., mobile phones, tablet computers, etc.). However, the yield of camera modules using liquid lenses is currently low, so the cost of electronic devices using liquid lenses is high. Summary of the Invention [Problem to be solved by the invention]

[0008] When assembling the camera module of the present disclosure, the liquid lens may be assembled to the motor and the solid lens may be assembled independently to the motor by fixing the fixed body to the second end and fixing the support to the first end, in which case the second optical axis is joined to the first optical axis. In this way, the liquid lens and the solid lens are assembled to the motor, respectively, and the manufacturing error of the solid lens and the assembly error with the motor do not cause an accumulation of assembly errors in the attachment of the liquid lens, so that the alignment between the second optical axis of the solid lens and the first optical axis of the liquid lens becomes accurate, and the precision requirements of the camera module meet the design requirements. In other words, the yield of the camera module of the present disclosure can be increased, which is advantageous for reducing the manufacturing cost of the camera module of the present disclosure, making it easier to apply the camera module of the present disclosure to electronic devices, and meeting the development needs for miniaturization of electronic devices.

[0014] The description of the accompanying drawings constitutes a part of the accompanying drawings of the present disclosure to provide a further understanding of the present disclosure, and the illustrative embodiments of the present disclosure and the description thereof are used to interpret the present disclosure and are not intended to unduly limit the present disclosure.

[0015] In order to more clearly explain the technical solutions in the embodiments of the present disclosure, the following will briefly describe the accompanying drawings that need to be used in the description of the embodiments. Obviously, the accompanying drawings in the following description are only some embodiments of the present disclosure, and those skilled in the art can further obtain other accompanying drawings based on these accompanying drawings without any creative work.

[0016] In order to further clarify the objectives, technical solutions and advantages of the present disclosure, the present disclosure will be described in more detail below in combination with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely used to interpret the present disclosure and do not limit the protection scope of the present disclosure.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terms used in the specification of this disclosure are intended to describe specific embodiments only and are not intended to be limiting of the present invention.

[0018] For ease of understanding, the following will first explain and define technical terms used in the embodiments of the present disclosure.

[0019] The optical axis is the direction in which an optical system transmits light rays and refers to the chief ray of the central field of view. For symmetrical transmission systems, it usually coincides with the center line of rotation of the optical system.

[0020] Focal length, also called focal length, is a measurement method for measuring the convergence or divergence of light in an optical system. It refers to the distance from the optical center of a lens to the focal point when a scene at infinity is imaged sharply on the focal plane through the lens. In the case of a fixed-focus lens, the focal length is constant because the position of its optical center is constant, while in the case of a zoom lens, the focal length of the lens changes depending on the optical center of the lens, so the focal length is adjustable.

[0021] A long focal length lens is a photographic lens with a focal length longer than that of a standard lens, and is also called a telephoto lens. The focal length varies from 100mm to 800mm, and some are even longer.

[0022] At present, electronic devices such as mobile phones, tablet computers, cameras, surveillance devices, drones, etc. are playing an increasingly important role in people's lives, bringing a lot of convenience and enjoyment to people's lives. Cameras are an important part of electronic devices for capturing images, but there are many types and brands of electronic devices with image capture functions, so consumers can choose from a wide range of electronic devices. How to attract consumers' attention and improve product competitiveness has become an increasingly important issue for electronic device manufacturers.

[0023] For the sake of aesthetics and portability, electronic devices also need to meet the development needs of miniaturization. In order to obtain a larger number of focal adjustments, the size of the lens is also becoming larger and larger, and in addition to setting the focal adjustment space, the volume of the camera module is also becoming larger and larger, which needs to occupy a very large amount of internal space in the electronic device, which seriously affects the layout of other internal elements of the electronic device.

[0024] Therefore, liquid lenses, which can meet the development needs of miniaturization of electronic devices, are increasingly applied to electronic devices (such as mobile phones, tablet computers, etc.). However, currently, the yield of camera modules using liquid lenses is low, which increases the cost of the camera modules, which is disadvantageous for applying the camera modules to electronic devices and further restricts the development of miniaturization of electronic devices.

[0025] Based on this, the present disclosure provides a camera module and optimizes the assembly structure, thereby increasing the mass production yield of the camera module of the present disclosure, reducing the manufacturing cost of the camera module of the present disclosure, and further advantageously reducing the application cost of liquid lenses in electronic devices.

[0026] The camera module of the present disclosure will now be described in conjunction with the accompanying drawings.

FIG. 2 is a schematic half-sectional view of a camera module shown in another embodiment. FIG. 3 is a schematic structural diagram of a camera module shown in another embodiment.

FIG. 10 is a schematic side view of the liquid lens shown in FIG. 9.

[0028] In some embodiments of the present disclosure, as shown in Figures 1, 2a, 2b or 3 to 5, a camera module 10 is provided, which includes a liquid lens 100, a motor 200 and a solid lens 300, where the liquid lens 100 includes a fixed body 120 and a support 110 spaced apart from the fixed body 120, the liquid lens 100 is provided with a first optical axis 130, the motor 200 includes a rotor component 210 and a stator component 220, where the rotor component 210 includes a first end 211 fixedly connected to the support 110, the rotor component 210 is movable along the direction of the first optical axis 130 relative to the stator component 220 to adjust the curvature of the liquid lens 100, the stator component 220 includes a second end 221 fixedly connected to the fixed body 120, and the solid lens 300 includes a second optical axis 310 fixed to the stator component 220 and joining the first optical axis 130.

[0029] In this way, when assembling the camera module 10 of the present disclosure, the fixed body 120 is fixedly connected to the second end 221, and the support 110 is fixedly connected to the first end 211, so that the liquid lens 100 can be assembled to the motor 200, and the solid lens 300 can be assembled independently to the motor 200, in which case the second optical axis 310 is joined to the first optical axis 130. In this way, the liquid lens 100 and the solid lens 300 are respectively assembled to the motor 200, and the manufacturing error of the solid lens 300 and the assembly error with the motor 200 do not cause an accumulation of assembly errors in the attachment of the liquid lens 100 and affect the attachment accuracy of the liquid lens 100, so that the alignment between the second optical axis 310 of the solid lens 300 and the first optical axis 130 of the liquid lens 100 is accurate. Furthermore, when attaching the liquid lens 100, fine adjustment control is performed on the attachment error of the liquid lens 100 based on the error of the solid lens 300, so that the alignment between the first optical axis 130 of the liquid lens 100 and the second optical axis 310 of the solid lens 300 can be made more accurate, so that the precision requirements of the camera module can satisfy the design requirements, and the scrap rate can be reduced. That is, according to the structure of the camera module of the present disclosure, the accumulation of errors can be reduced, and the yield of the camera module of the present disclosure can be increased, which is advantageous for reducing the manufacturing cost of the camera module of the present disclosure, makes it easier to apply the camera module of the present disclosure to electronic devices, and meets the development needs for miniaturization of electronic devices.

[0030] In addition, the camera module of the present disclosure has the following advantages by applying the liquid lens. The liquid lens 100 is a liquid lens with a variable curvature, and the refractive power can be continuously changed by driving, adjusting, and controlling the liquid lens, thereby realizing continuous focusing from a distant view to a close view. This focusing method reduces the requirements for the driving stroke of the motor 200 and enables focusing at a very close distance, thereby greatly improving the optical magnification and realizing background blur macro photography close to the viewing angle commonly used by single-lens reflex cameras. The liquid material has the properties of an ultra-low refractive index and ultra-low dispersion, which is lower than that of fluorite used in the super telephoto of single-lens reflex cameras, and therefore greatly reduces the change in chromatic aberration during focusing. Therefore, in combination with electronic zoom, the liquid lens 100 can realize macro imaging with a higher magnification. That is, the camera module of the present disclosure can guarantee the macro effect and sufficiently reduce the size of the entire module, and further meet the development needs for miniaturization of electronic devices.

[0031] In addition, by applying the liquid lens 100, the camera module of the present disclosure can reduce the change in FOV (angle of view) from distant views to close views, and there is almost no breathing effect from distant views to general close views, making it suitable for video capture.

[0032] When assembling the camera module of the present disclosure, the solid lens 300 may be attached first, followed by the liquid lens 100, or the liquid lens 100 may be attached first, followed by the solid lens 300. By fine-tuning the attachment position of the solid lens 300, the alignment between the first optical axis 130 of the liquid lens 100 and the second optical axis 310 of the solid lens 300 can be made more accurate.

[0033] The specific realization form of the "liquid lens 100" is diverse and can be selected arbitrarily.

[0034] In one example, liquid lens 100 includes a lens body (not numbered) and a liquid (not shown) disposed within the lens body, with the lens body provided with movable supports 110. In this manner, the movement of rotor component 210 can push or pull support 110 to change the shape of the lens body, adjust the shape of the liquid within the lens body, and adjust the curvature of liquid lens 100, such that the focal length of liquid lens 100 changes accordingly.

[0035] In addition, specific implementation forms of the "fixed connection" between the stator component 220 and the fixed body 120 include at least one of engagement fixation, screw fixation, adhesive fixation, welding fixation, and fusion fixation, but are not limited to these.

[0036] Similarly, specific implementations of the “fixed connection” between the rotor component 210 and the support 110 include, but are not limited to, at least one of engagement fixation, screw fixation, adhesive fixation, welding fixation, and fusion fixation.

[0037] A conventional camera module is mainly composed of a solid lens 300, which includes a lens group consisting of multiple lenses (not shown), and a motor 200 directly couples the lens barrel to which the lens group is fixed so as to move the lens barrel as a whole a fixed distance or rotate it a fixed angle, thereby achieving autofocus and / or optical image stabilization.

[0038] The lens material of the conventional solid lens is made of glass, optical plastic, etc., and has a constant radius of curvature after processing and molding. It is mounted on the drive of the motor 200, and by moving in the optical axis direction, the focus position is changed, and continuous focus from distant to close is realized. There is a limit to it, that is, when the lens group is moved to realize macro imaging, the stroke movement amount is large, and especially when an ultra-close image is formed by a telephoto lens, the required movement amount is too large, and it is difficult to realize it in electronic devices such as mobile phones and tablet computers because the stroke of the motor 200 is limited or the internal space of the electronic device is limited. In particular, when using the solid lens 300 to realize long focal length adjustment, the stroke of the motor 200 is required to be sufficiently long, and it is also necessary to leave sufficient space inside the electronic device, which is disadvantageous to the development of miniaturization of electronic devices or cannot be used in small electronic devices.

[0039] As shown in Fig. 1, Fig. 2a, Fig. 2b or Fig. 5, in some embodiments, the stator component 220 includes a housing 223 with a second end 221, the housing 223 with a receiving cavity 2231 and a first opening 2232 communicating with the receiving cavity 2231, the first opening 2232 is provided at the second end 221, the rotor component 210 is provided in the receiving cavity 2231, and the support 110 passes through the first opening 2232 and is fixedly connected to the rotor component 210. In this way, the rotor component 210 is provided in the receiving cavity 2231 and protected by the housing 223, which is advantageous to extend the service life of the rotor component 210 and reduce interference during running, and further improve the accuracy of the motor 200.

[0040] 1 or 2a and 2b, in some embodiments, the stator component 220 includes a magnet module 224 mounted on a side wall of the receiving cavity 2231, the rotor component 210 includes a movable bracket 213 and a voice coil module 214 mounted on the movable bracket 213, the movable bracket 213 and the side wall of the receiving cavity 2231 are spaced apart from each other, and the end of the movable bracket 213 is adhesively fixed to the support 110, and the voice coil module 214 and the magnet module 224 are magnetically engaged with each other. In this way, the voice coil module 214 and the magnet module 224 are magnetically excited and engaged with each other to realize the movement of the voice coil relative to the magnet module 224, and can further be interlocked to move the movable bracket 213, which finally transmits a displacement force to the support 110 and realizes the curvature of the liquid lens 100 being adjusted by the motor 200.

[0041] 5, in one embodiment, the rotor component 210 further includes an elastic piece 212, which is fixedly connected to the movable bracket 213, and the movable bracket 213 is fixedly connected to the support 110 through the elastic piece 212, so that the movable bracket 213 presses or pulls the liquid lens 100 through the elastic piece 212. In this way, the movable bracket 213, in combination with the elastic piece 212 of the above embodiment, can realize the pressing or pulling of the liquid lens 100 and adjust the shape of the liquid inside the lens body. After the driving force of the magnet module 224 is removed, the elastic piece 212 can automatically return, and can be linked to return the liquid lens 100, the movable bracket 213, and the voice coil module 214.

[0042] 6 and 7, in one embodiment, the housing 223 includes a clamp portion 203 disposed in the receiving cavity 2231, the solid lens 300 is at least partially disposed in the receiving cavity 2231, and the solid lens 300 includes a buckle portion 320 that engages with the clamp portion 203. In this manner, the engagement between the clamp portion 203 and the buckle portion 320 allows the solid lens 300 to be disposed in the receiving cavity 2231 in an engaged and fixed manner, which is advantageous to improving the installation efficiency.

[0043] Furthermore, in one embodiment, the housing 223 is provided with a second opening 2233 communicating with the accommodating cavity 2231, the second opening 2233 is provided opposite the first opening 2232, and the clamp portion 203 is provided adjacent to the first opening 2232. In this manner, by using the second opening 2233 as an entrance for attaching the solid lens 300, it becomes easier to insert the solid lens 300 into the accommodating cavity 2231 from the second opening 2233, and the buckle portion 320 is engaged and fixed to the clamp portion 203.

[0044] Moreover, in one embodiment, the solid lens 300 includes a third end 330 provided opposite the buckle portion 320, the third end 330 being provided in the second opening 2233, and adhesively fixed to the housing 223. In this manner, when the solid lens 300 is fixed in the housing 223 by fitting the buckle portion 320 with the clamp portion 203, the solid lens 300 can be further fixed with an adhesive so as to firmly fix the solid lens 300 to the housing 223, thereby improving the drop resistance of the camera device of the present disclosure and improving the reliability of the camera device of the present disclosure.

[0045] It should be noted that the manner of fixing the solid lens 300 to the housing 223 can be varied. As shown in FIG. 2a, in another embodiment, the housing 223 includes an annular housing 2234 and a base 2235, the annular housing 2234 is hollow, and a first opening 2232 is provided at one end of the annular housing 2234, the solid lens 300 is fixed to the base 2235, and the base 2235 is provided at the other end of the annular housing and fixedly connected to the annular housing 2234 to form a receiving cavity 2231. In this way, the solid lens 300 can be modularly assembled to the base 2235, the stator component 220 and the rotor component 210 can be modularly assembled to the annular housing 2234, and the base 2235 can be assembled to the annular housing 2234 to simultaneously realize the assembly of the solid lens 300 to the motor 200, which is favorable for improving the assembly efficiency.

[0046] 8 to 10, in some embodiments, the housing 223 is provided with a guide portion 2236, the guide direction of the guide portion 2236 is provided along the depth direction of the receiving cavity 2231, and the support 110 includes a stopper portion 111, which is guide-fitted into the guide portion 2236 so as to limit the movement range of the support 110 in the axial direction of the first optical axis 130. In this way, the engagement between the stopper portion 111 and the guide portion 2236 can limit the movement range of the support 110, which is advantageous to ensuring the reliability of the focus adjustment process of the liquid lens 100.

[0047] The specific fitting structure between the guide portion 2236 and the stopper portion 111 is diverse, and includes, but is not limited to, a guide plate and a guide block, a chute and a slider, and the like.

[0048] In some embodiments, the solid lens 300 and the liquid lens 100 are combined to form a long focal length lens structure, in this way, compared with the traditional long focal length lens, the movement stroke can be reduced, and the size of the module can be sufficiently reduced while ensuring the macro effect, and the traditional Hall sensor can also accurately sense the actual position of the solid lens 300, which is advantageous for reducing application costs.

[0049] In one example, the shortest focus distance F of the focus range of the long focal length lens is ≧1 cm. Furthermore, the camera module of the present disclosure can realize super macro adjustment and has better image acquisition performance. For example, the shortest focus distance F of the focus range may be 1 cm and the corresponding focus range may be from 1 cm to infinity, or the shortest focus distance F of the focus range may be 1.5 cm and the corresponding focus range may be from 1.5 cm to infinity, or the shortest focus distance F of the focus range may be 2 cm and the corresponding focus range may be from 2 cm to infinity, or the shortest focus distance F of the focus range may be 3 cm and the corresponding focus range may be from 3 cm to infinity, or the shortest focus distance F of the focus range may be 7 cm and the corresponding focus range may be from 7 cm to infinity, or the shortest focus distance F of the focus range may be 10 cm and the corresponding focus range may be from 10 cm to infinity, or the shortest focus distance F of the focus range may be 20 cm and the corresponding focus range may be from 20 cm to infinity, or the shortest focus distance F of the focus range may be 30 cm and the corresponding focus range may be from 30 cm to infinity.

[0050] Similarly, the shortest focus distance F of the focus range of the long focal length lens of the present disclosure may be ≧2 cm, ≧3 cm, ≧7 cm, ≧10 cm, ≧20 cm, ≧30 cm, etc.

[0051] In some embodiments, the first end 211 is adhesively fixed to the support 110. In this way, when assembling the camera module of the present disclosure, in the process of adhesively fixing the first end 211 to the support 110, an initial fixation by adhesive can be performed first. In this case, the positional relationship between the movable member of the liquid lens 100 and the moving member of the motor 200 can still be fine-tuned, that is, the positional relationship between the rotor component 210 and the support 110 can still be fine-tuned. If the positions of the liquid lens 100 and the motor 200 meet the assembly requirements, they are reliably adhesively fixed. Furthermore, by correcting the positioning error and / or manufacturing error of the liquid lens 100 and the motor 200, the assembly error of the liquid lens 100 and the motor 200 can meet the manufacturing requirements, and the accuracy requirements of the camera module can meet the design requirements, and the yield of the camera module of the present disclosure can be increased, which is advantageous for reducing the manufacturing cost of the camera module of the present disclosure.

[0052] 2a, 2b or 5, in one example, the camera module 10 further includes a first adhesive layer 11, and the first end 211 is adhesively fixed to the support 110 via the first adhesive layer 11. In this manner, the first adhesive layer 11 facilitates the fixing of the stator component 210 to the support 110. In order to facilitate the initial fixing and correct positioning errors or manufacturing errors, an adhesive such as a solid or liquid, or a double-sided adhesive may be provided on the rotor component 210 in advance and then cured to firmly fix the rotor component 210 to the support 110.

[0053] Optionally, the first adhesive layer 11 is formed by solidifying the adhesive. In this way, after the rotor component 210 and the support 110 are initially fixed with the adhesive, during the gradual solidification, it can be measured whether the assembly error between them meets the requirements, and if not, it can be further fine-tuned to ensure that the assembly error between the liquid lens 100 and the motor 200 meets the manufacturing requirements and guarantees the precision requirements of the camera module. The adhesive includes, but is not limited to, a thermosetting adhesive and an ultraviolet curing adhesive.

[0054] Based on any of the above embodiments, in some embodiments, the second end 221 is adhesively fixed to the fixed body 120. In this way, the stator component 220 and the fixed body 120 can also be initially fixed, and can be further adaptively fine-tuned to further improve the adjustment flexibility between the liquid lens 100 and the motor 200 to compensate for larger manufacturing errors and reduce the impact of the accumulation of manufacturing errors on assembly accuracy.

[0055] 2a, 2b or 5, in one example, the camera module 10 further includes a second adhesive layer 12, and the second end 221 is adhesively fixed to the fixed body 120 via the second adhesive layer 12. In this manner, the second adhesive layer 12 facilitates adhesive fixation of the stator component 220 and the fixed body 120. In order to facilitate initial fixation and correct positioning errors or manufacturing errors, an adhesive such as a solid or liquid, or a double-sided adhesive may be provided on the stator component 220 in advance and then cured to firmly fix the stator component 220 and the fixed body 120.

[0056] Optionally, the second adhesive layer 12 is formed by solidifying the adhesive. In this way, after the initial fixing of the stator component 220 and the fixed body 120 with the adhesive, during the gradual solidification, it can be measured whether the assembly error of the two meets the requirements, and if not, it can be further fine-tuned to ensure that the assembly error of the liquid lens 100 and the motor 200 meets the manufacturing requirements and guarantees the precision requirements of the camera module. The adhesive includes, but is not limited to, a thermosetting adhesive and an ultraviolet curing adhesive.

[0057] Similarly, an adhesive method can be adopted as a method for fixing the solid lens 300 and the stator component 220, which allows initial fixing first and then hardening, making it easy to make fine adjustments during hardening, thereby improving the attachment accuracy of the solid lens 300 and the stator component 220 and further improving the accuracy with which the camera module acquires images.

[0058] 5 or 8, in some embodiments, the rotor component 210 further includes an elastic piece 212, and the first end 211 is fixedly connected to the support 110 through the elastic piece 212, and the rotor component 210 presses or pulls the liquid lens 100 through the elastic piece 212. By realizing the pressing or pulling of the liquid lens 100 by the elastic piece 212, the shape of the liquid inside the lens body can be adjusted, and after the driving force by the rotor component 210 is removed, the elastic piece 212 can automatically return and be linked to return the liquid lens 100.

[0059] Furthermore, the elastic piece 212 is adhesively fixed to the support 110. In this way, by adhesively fixing the first end 211 to the support 110 via the elastic piece 212, an initial fixation by adhesion can be performed first in the process of adhesively fixing the support 110. In this case, the positional relationship between the movable member of the liquid lens 100 and the moving member of the motor 200 can still be fine-tuned, that is, the positional relationship between the rotor component 210 and the support 110 can be fine-tuned. When the positions of the liquid lens 100 and the motor 200 meet the assembly requirements, the liquid lens 100 can automatically elastically return by being reliably adhesively fixed, and the installation accuracy is improved.

[0060] In one example, a through hole 2121 is provided in the center of the elastic piece 212, a first avoidance space 230 is provided between the elastic piece 212 and the liquid lens 100, and the first avoidance space 230 communicates with the through hole 2121. In this way, the solid lens 300 can be provided in the first avoidance space 230 through the through hole 2121, making full use of the space to make the structure of the camera module more compact and favorable for the miniaturization design of the camera module. At the same time, the liquid lens 100 can be deformed by using the first avoidance space 230 to make full use of the internal space of the camera module.

[0061] As shown in FIG. 8 to FIG. 10, in one embodiment, the second end 221 includes a first adhesive receiving surface 201 provided on the end face of the second end 221 and a receiving surface 202 provided below the first adhesive receiving surface 201, and the fixed body 120 includes a second adhesive receiving surface 121 provided opposite the first adhesive receiving surface 201 and a mating surface 122 in contact with the receiving surface 202. In this way, the first adhesive receiving surface 201 and / or the second adhesive receiving surface 121 can be used to receive the adhesive. For example, the adhesive is applied to the first adhesive receiving surface 201 using a dispenser, and then the mating surface 122 of the fixed body 120 is provided on the receiving surface 202, so that the second adhesive receiving surface 121 and the first adhesive receiving surface 201 can be easily fixed by the adhesive. At the same time, the liquid lens can be prevented from being excessively pulled by using the receiving surface 202 to be engaged with the mating surface 122.

[0062] In some embodiments, the positioning structure can better align the liquid lens 100 and the motor 200, thereby improving the assembly accuracy of the two.

[0063] 2b, the first end 211 is provided with a first positioning portion 204, and the support 110 is provided with a second positioning portion 112 that is positioned and fitted into the first positioning portion. In this way, by positioning and fitting the first positioning portion 204 and the second positioning portion 112, the assembly accuracy of the first end 211 and the support 110 can be improved.

[0064] In one example, the second end 221 is provided with a third positioning portion 222, and the fixed body 120 is provided with a fourth positioning portion 123 that is positioned with and fits into the third positioning portion. In this way, by positioning and fitting the third positioning portion 222 and the fourth positioning portion, the assembly accuracy of the second end 221 and the fixed body 120 can be improved.

[0065] The specific structures between the "first positioning portion" and the "second positioning portion", and between the "third positioning portion" and the "fourth positioning portion" are diverse and include at least one of a positioning convex portion and a positioning concave portion, a positioning convex portion and a positioning hole, etc., but are not limited to these.

[0066] In one example, a recess is provided in the third positioning portion 222, and a protrusion that fits into the recess is provided in the fourth positioning portion 123. In this way, by fitting the protrusion and the recess, positioning can be achieved when assembling the fixed body 120 and the second end portion 221, and at the same time, it can also function as a stopper, and further improve the assembly accuracy of both and the strength of the fixation between them.

[0067] As shown in FIGS. 3 to 5, in some embodiments, the camera module further includes a substrate 400, the substrate 400 is fixed to the stator component 220, a filter 410 is provided on the substrate 400, and the filter 410 and the solid lens 300 are spaced apart to form a second avoidance space 420. In this way, the filter 410 is fixed to the stator component 220 via the substrate 400, and the light output from the solid lens 300 can be filtered, so that the interference can be reduced and the effective light captured by the image sensor 520 can be enhanced. At the same time, the second avoidance space 420 forms a focus adjustment space for the solid lens 300 to facilitate focus adjustment of the solid lens 300.

[0068] The filter 410 is an infrared filter 410 and can further filter infrared light to reduce interference of infrared light with the capture of a particular image.

[0069] Furthermore, in one embodiment, the camera module further includes an image sensor component 500, which includes an image transmission circuit board 510 and an image sensor 520 disposed on the image transmission circuit board 510, and the image sensor 520 is disposed directly below the filter 410. In this way, the image sensor component 500 can be directly integrated into the camera module, which is advantageous to improve the assembly efficiency of the electronic device, and is advantageous to ensure that the assembly error of the camera module in the electronic device does not affect the electronic device from acquiring image information, and to improve the accuracy of the image information acquired by the electronic device.

[0070] According to another embodiment of the present disclosure, as shown in FIG. 11, there is further provided an electronic device 1 including a controller 20 and a camera module 10 as described in any of the above embodiments, the controller 20 being communicatively connected to a motor.

[0071] By using the above-mentioned camera module 10, the electronic device of the present disclosure has the same focus adjustment range and can be designed to be compact, especially when ultra-close focus can be achieved.In addition, since the manufacturing cost of the camera module 10 of the present disclosure is low, it is further advantageous in reducing the manufacturing cost of the electronic device of the present disclosure.

[0072] The electronic devices may include handheld devices, in-vehicle devices, wearable devices, surveillance devices, cellular phones, smart phones, personal digital assistant (PDA) computers, tablet computers, portable computers, laptop computers, video cameras, video recorders, cameras, smart watches, smart wristbands, in-vehicle computers, and other electronic devices with imaging capabilities.
