[0037] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

These terms are mainly used for better describing the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0039] In addition, in addition to being used to indicate the orientations or positional relationships, the above-mentioned terms can also be used to indicate other meanings, for example, the term “upper” can also be used to indicate a certain dependent relationship or connection relationship in some cases. Those of ordinary skill in the art can understand the specific meanings of these terms in the present application according to the specific circumstances.

[0040] In addition, the terms “mounting”, “setting”, “provided with”, “connection”, “connected” should be understood broadly. For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium, or internal communication between two devices, elements or components. Those of ordinary skill in the art can understand the specific meanings of the above-mentioned terms in the present application according to the specific circumstances.

[0041] In addition, the terms “first”, “second” and the like are mainly used to distinguish different devices, elements or components, and the specific types and structures of which can be the same or different, and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of “multiple” is two or more.

[0042] As mentioned in the background, in the related art, the lens barrel is usually fixed by dispensing adhesive between the two side walls of the lens barrel and the inner wall of the lens carrier. If the adhesive shrinks, the true circularity in the lens barrel will change, which will cause the position of the lens to change, and seriously affect the imaging quality.

[0043] To solve the above problems, the application provides a camera module and an electronic device. By clamping and matching the first clamping part on the outer circumferential surface of the lens barrel and the second clamping part in the lens carrier accommodating cavity, the position of the lens barrel is prevented from changing due to the shrinkage of the adhesive, effectively solving the problem of the change of the position of the lens caused by the shrinkage of the adhesive and the like, thereby ensuring the accuracy of the path of light when passing through the lens, improving the clarity and contrast of imaging, and ensuring the imaging quality.

[0044] The technical solutions of the application will be further described below with reference to specific embodiments and the accompanying drawings.

[0045] Referring to Figures 1 to 5 The application provides a camera module 1, which comprises a plurality of lenses 100 and a lens carrier 200. Each lens 100 comprises a lens barrel 110 and a lens (not shown in the figure) arranged in the lens barrel 110. The outer circumferential surface of the lens barrel 110 is provided with a first clamping part 1101. The lens carrier 200 has an accommodating cavity 210. The plurality of lenses 100 are arranged in the accommodating cavity 210. The plurality of lenses 100 are arranged along the optical axis direction of the lens 100, and at least one lens 100 is configured to be movable along the optical axis direction of the lens 100 to realize zooming or focusing of the camera module 1. The accommodating cavity 210 is provided with a second clamping part 2101. The second clamping part 2101 is clamped and matched with the first clamping part 1101 to limit the plurality of lens barrels 110 along the optical axis direction.

[0046] The optical axis direction of the lens is the direction indicated by the arrow X in Figure 3

[0047] It should be noted that the outer circumferential surface of the lens barrel 110 is understood as the outer surface of the lens barrel 110 facing the inner wall of the accommodating cavity 210.

[0048] In addition, at least one movable part capable of moving along the optical axis direction can be arranged in the accommodating cavity 210. At least one lens 100 is mounted on the movable part, so that the lens can move along the optical axis direction of the lens 100 to realize zooming or focusing of the camera module 1. The movable part is provided with a second clamping part 2101 clamped and matched with the first clamping part 1101 to limit the lens barrel 110 along the optical axis direction, so as to prevent the lens barrel 110 from moving relative to the movable part along the optical axis direction.

[0049] ​By clamping the first clamping part 1101 of the outer circumferential surface of the lens barrel 110 and the second clamping part 2101 in the accommodating cavity 210 of the lens carrier 200, the lens barrel 110 can be effectively limited when the plurality of lenses 100 move along the optical axis direction. When the adhesive between the lens barrel 110 and the accommodating cavity 210 shrinks, the shrinkage of the adhesive will generate a certain force, and the clamping structure can provide sufficient resistance to offset this shrinkage force, avoiding the change of the position of the lens barrel 110 due to the shrinkage of the adhesive. Since the position of the lens barrel 110 is stable, the roundness in the lens barrel 110 can also be better maintained, reducing the change of the lens position caused by the change of the roundness, effectively solving the problem of the change of the lens position caused by the shrinkage of the adhesive and other factors, thereby ensuring the accurate path of light when passing through the lens, improving the clarity and contrast of the image, and ensuring the imaging quality.

[0050] In addition, when the camera module 1 is a three-group periscopic zoom camera module, it is composed of three different lenses 100. The three-group periscopic zoom camera module 1 can provide continuous optical zoom from low to high magnification, for example, optical zoom between 3 times and 5 times. By moving the second and third lenses 100, the focal lengths of the lenses are changed to achieve different zoom effects. This zooming method can meet the needs of users in different shooting scenes without losing image quality, and can easily cope with shooting distant scenes and close-up shots. In addition, since multiple lenses 100 are used, the light can be more precisely controlled and adjusted to improve the clarity, contrast, and color reproduction of the image. The lens carrier 200 is a voice coil motor lens carrier 200, mainly composed of a coil, a magnet, a spring, and a carrier. The carrier is a component that carries the lens, that is, the "lens carrier 200". When the coil is energized, it will generate a force in the magnetic field, pushing the sliding seat 230 in the lens carrier 200 to move the lens barrel 110, thereby achieving focusing or zooming functions. By controlling the size and direction of the current in the coil, the displacement of the sliding seat 230 can be accurately controlled. The voice coil motor lens carrier 200 can respond to control signals in a very short time, quickly adjust the lens position, meet the needs of high-speed automatic focusing and zooming, and achieve micron-level or even higher precision lens displacement control to ensure the clarity and accuracy of the image. In addition, when the three-group periscopic zoom camera module is applied to smartphones and tablets, it can solve the problem of difficult installation of long focal length lenses in the trend of thinness. By using a periscopic structure inside the body, the light path is changed using a prism to refract light inside the body, thereby achieving high magnification optical zoom without increasing the thickness of the body.

[0051] In one possible embodiment, the participants Figure 4 and Figure 5The first clamping portion 1101 is a clamping protrusion provided on the outer peripheral surface of the lens barrel 110 , and the second clamping portion 2101 is a clamping groove provided on the inner wall of the accommodating cavity 210 .

[0052] Thus, the snap-fitting protrusion can be tightly embedded in the snap-fitting groove, so that the position of the lens barrel 110 in the accommodating cavity 210 is accurately fixed to prevent it from moving in the direction of the optical axis. Since the position of the lens barrel 110 is effectively fixed, the lens in the lens barrel 110 can also be kept in an accurate position, which can ensure that the path of light passing through the lens is accurate, thereby improving the clarity and color reproduction of the image. In addition, when producing and assembling the camera module 1, the design of the snap-fitting protrusion and the snap-fitting groove enables the lens barrel 110 to be quickly and accurately installed in the accommodating cavity 210 of the lens carrier 200. The operator only needs to align the snap-fitting protrusion of the lens barrel 110 with the snap-fitting groove and push it in to complete the camera assembly. The installation of the barrel 110 improves production efficiency. In addition, when the terminal requires an extremely small size, this clamping structure can achieve stable fixation of the lens barrel 110 without increasing additional space. The sizes of the clamping protrusions and the clamping grooves can be designed according to actual needs, so that the camera module 1 can maintain good performance and stability while meeting the small size requirements. The design of the clamping structure can better cooperate with other components of the small-sized camera module 1 and optimize the overall layout. For example, the position of the clamping groove can be reasonably arranged on the lens carrier 200 to leave more space for other electronic components or optical components, thereby improving the integration of the camera module 1.

[0053] Of course, the first clamping portion 1101 and the second clamping portion 2101 are not limited to the above forms. For example, the first clamping portion 1101 can also be a clamping groove set on the outer surface of the lens barrel 110, and the second clamping portion 2101 can be a clamping protrusion set on the inner wall of the accommodating cavity 210.

[0054] In one possible embodiment, see Figure 6 The locking protrusion extends along a first direction, and the first direction is perpendicular to the optical axis.

[0055] Among them, the first direction is Figure 6 The direction indicated by arrow Y.

[0056] Since the snap-fit ​​protrusion extends perpendicularly to the optical axis, it can provide strong resistance to the lens barrel 110 in the optical axis direction, preventing the lens barrel 110 from being displaced in the optical axis direction. Moreover, the snap-fit ​​protrusion perpendicular to the optical axis direction does not occupy too much space in the optical axis direction, so that the camera module 1 can effectively limit the lens barrel 110 while meeting the small size requirements.

[0057] In one possible embodiment, see Figure 6The two clamping protrusions are symmetrically arranged on the outer peripheral surface of the lens barrel 110 along the first direction.

[0058] The two symmetrically arranged snap-fit ​​protrusions can provide balanced supporting force for the lens barrel 110 in the direction of the optical axis. When the lens barrel 110 is subjected to external force, the two snap-fit ​​protrusions share the force together, preventing the lens barrel 110 from tilting or displacing due to unilateral force, ensuring the stability of the position of the lens barrel 110 in the accommodating cavity 210 of the lens carrier 200. The symmetrical snap-fit ​​structure can make the lens barrel 110 more evenly stressed during installation and use, reducing the risk of deformation of the lens barrel 110 due to uneven force, helping to maintain the shape and dimensional accuracy of the lens barrel 110, ensuring the accurate position of the lens in the lens barrel 110, and thus improving the imaging quality.

[0059] In one possible embodiment, see Figure 2 and Figure 4 The mirror carrier 200 includes an opening 220 communicating with the accommodating cavity 210 ; the surface of the snap-fit ​​protrusion facing the opening 220 is flush with the surface of the lens barrel 110 facing the opening 220 .

[0060] Therefore, when the lens barrel 110 is inserted into the accommodating cavity 210 of the lens carrier 200, since the surface of the snap-fitting protrusion facing the opening 220 is flush with the surface of the lens barrel 110 facing the opening 220, the lens barrel 110 can enter the accommodating cavity 210 more smoothly through the opening 220, reducing the jamming or obstruction that may be caused by the uneven surface, making the assembly process more efficient. When the camera module 1 needs to be maintained or the lens barrel 110 needs to be replaced, the flush surface makes it easier to remove the lens barrel 110 from the opening 220, reducing the difficulty and time cost of maintenance. Moreover, when the lens barrel 110 is combined with the lens carrier 200, the snap-fitting protrusion and the lens carrier 200 will not produce local stress concentration due to the uneven surface, thereby reducing the risk of damage to the lens barrel 110 and the lens carrier 200 due to uneven force during use.

[0061] In one possible embodiment, see Figure 3 Along the optical axis direction of the lens 100 , the thickness of the clamping protrusion is smaller than the thickness of the lens barrel 110 , and the clamping protrusion is located in the middle of the lens barrel 110 .

[0062] In the direction of the optical axis, the thickness of the clamping protrusion is less than the thickness of the lens barrel 110, so that in a limited space, the combination of the lens barrel 110 and the lens carrier 200 is more compact, and the thinner clamping protrusion can better adapt to this environment, so that the camera module 1 can be more easily installed in a narrow space without interfering with other components, and the clamping protrusion is located in the middle of the lens barrel 110, which can make the stress of the lens barrel 110 more evenly distributed on the lens barrel 110 when subjected to external force. Compared to setting the clamping protrusion at the edge position, the middle position can better resist bending and twisting force, improving the structural stability of the lens barrel 110.

[0063] In a possible embodiment, the clamping protrusion is integrally formed on the lens barrel 110.

[0064] The integral forming makes the clamping protrusion and the lens barrel 110 an integral whole without connection gaps or weak points, enhancing the overall structural strength of the lens barrel 110, and compared to the clamping protrusion connected by welding, bonding or other means, the integrally formed clamping protrusion is less likely to break or fall off, which improves the reliability and durability of the camera module 1, prolongs its service life, and the clamping protrusion can be formed simultaneously in the process of the lens barrel 110, without the need for additional processing steps or assembly links, simplifying the production process, reducing production costs and improving production efficiency.

[0065] Of course, the clamping protrusion is not limited to being integrally formed on the lens barrel 110, for example, it can also be a threaded connection, a threaded hole is machined on the lens barrel 110, and then a clamping protrusion with external threads is screwed into the threaded hole for fixation. This way is convenient to install and disassemble, and can be adjusted and replaced as needed. At the same time, threaded connection can provide better stability and reliability, but the machining accuracy and fit of the threads need to be ensured; or press-fit, separately manufactured clamping protrusions are pressed into the pre-machined holes on the lens barrel 110 using a press or other equipment, and fixed by interference fit. This way is relatively simple to operate and has low cost, but the size of the pressing force needs to be controlled to avoid damage to the lens barrel 110; or adhesive fixing, using a suitable adhesive to paste the clamping protrusion on the lens barrel 110; and mechanical clamping, by designing a special clamping device to clamp the clamping protrusion on the lens barrel 110, as known by those skilled in the art.

[0066] In a possible embodiment, the clamping groove is a rectangular groove, and the clamping protrusion is a rectangular protrusion matching the rectangular groove.

[0067] In the direction of the optical axis, the rectangular protrusion can be closely fitted in the rectangular groove, effectively preventing the movement of the lens barrel 110 in this direction, and in the plane perpendicular to the optical axis, the rectangular structure can also limit the rotation and lateral displacement of the lens barrel 110, ensuring the stable and accurate position of the lens barrel 110 in the mirror carrier 200 accommodating cavity 210. The rectangular clamping structure has a larger contact area than other shapes (such as a circular shape), which can provide a stronger clamping force, making the connection between the lens barrel 110 and the mirror carrier 200 more secure and less likely to loosen or fall off. Even under the impact of external force or vibration, it can maintain a stable clamping state.

[0068] Of course, the shapes of the clamping groove and the clamping protrusion are not limited to the above forms, and can also be trapezoidal clamping grooves and trapezoidal clamping protrusions, semicircular clamping grooves and semicircular clamping protrusions, or triangular clamping grooves and triangular clamping protrusions, and the like. Those skilled in the art should know.

[0069] In a possible embodiment, an adhesive is provided between the clamping groove and the clamping protrusion.

[0070] The adhesive can be ultraviolet curing glue, which can quickly cure under ultraviolet irradiation, has a fast curing speed, a high bonding strength, and good transparency, and does not significantly affect the optical performance. In addition, the shrinkage rate of the ultraviolet curing glue is relatively low, which can reduce the impact on the circularity and other properties of the lens barrel 110. Alternatively, the adhesive can be a heat-curing glue, which is cured by heating. The bonding strength after curing is high, and the stability is good. The curing temperature and time can be adjusted according to different process requirements to meet different process requirements. The heat-curing glue usually has good temperature resistance and can maintain stable bonding performance within a certain temperature range. The adhesive can also be a two-component epoxy glue, which has a high bonding strength, good chemical corrosion resistance, and electrical insulation. The shrinkage rate is relatively low, and the hardness after curing is high, which can provide good support and fixing effect. Herein, the adhesive is not limited.

[0071] In this way, the clamping groove and the clamping protrusion not only have mechanical clamping, but also have the bonding force of the adhesive, forming double fixation, which greatly enhances the connection stability between the lens barrel 110 and the mirror carrier 200, thereby effectively preventing the loosening of the clamping part. In addition, compared with directly setting the adhesive on the lens barrel 110 body in the related art, the adhesive is set on the clamping protrusion in the present embodiment, which avoids the influence of the shrinkage of the adhesive on the circularity and other changes in the lens barrel 110, causing the position of the lens to change and affecting the imaging quality.

[0072] In a possible embodiment, referring to Figure 7 and Figure 8The clamping protrusion is provided with a plug-through hole 1101a; the clamping groove is provided with a plug-in column 2101a; the plug-in column 2101a is plugged into the plug-through hole 1101a along the thickness direction of the clamping protrusion; and a welding layer is arranged between the plug-through hole 1101a and the plug-in column 2101a.

[0073] Thus, the clamping protrusion is welded in the clamping groove, so that the clamping groove and the clamping protrusion are not only mechanically clamped but also fixed by the adhesive layer, forming double fixation, which greatly enhances the connection stability between the lens barrel 110 and the lens carrier 200, thereby effectively preventing the clamping part from loosening. In addition, the plug-through hole 1101a is arranged on the clamping protrusion, the plug-in column 2101a is arranged in the clamping groove, and the welding layer is arranged between the plug-through hole 1101a and the plug-in column 2101a, so that the connection strength is higher, and the adhesive does not need to be arranged at the clamping protrusion, thereby avoiding the influence of the adhesive shrinkage on the change of the true circularity in the lens barrel 110, the change of the lens position, and the influence on the imaging quality.

[0074] For example, the plug-through hole 1101a is a buried injection metal through hole, and the plug-in column 2101a is a buried injection metal column.

[0075] In a possible embodiment, referring to Figure 4 The accommodation cavity 210 includes at least one sliding seat 230 and a guide slide rail 240 matched with the sliding seat 230, the guide slide rail 240 is arranged on the inner wall of the accommodation cavity 210, the second clamping part 2101 is formed on the sliding seat 230, and at least one lens barrel 110 is arranged on the sliding seat 230.

[0076] Thus, the position of the lens 100 is adjusted in the optical axis direction by moving the sliding seat 230, so that the distance between the lenses 100 is changed to adjust the focal length, thereby providing the optical zoom effect and meeting the shooting requirements in different scenes.

[0077] In a possible embodiment, the camera module 1 has an entrance end and an exit end, the entrance end is provided with a prism 300, the exit end is provided with a photosensitive chip 400, and the sliding seat 230 is arranged close to the exit end.

[0078] By arranging the sliding seat 230 near the light-emitting end, the light can reach the image sensor or other receiving device as quickly as possible after being focused and adjusted by the lens group, thereby reducing the propagation path inside the camera module 1, thereby reducing the interference that the light may receive during the propagation process, such as reflection, scattering, etc., and improving the clarity and contrast of the imaging. In addition, since the sliding seat 230 is close to the light-emitting end, the impact on the imaging is more direct and obvious when performing a zoom operation, and the focal length and focus can be adjusted more accurately, so that the image can maintain a high quality at different zoom factors, reducing the occurrence of optical defects such as aberrations and distortions. In addition, in some camera modules 1 with automatic zoom functions, arranging the sliding seat 230 near the light-emitting end can make it more convenient to connect and cooperate with external control devices (such as motors, sensors, etc.). In this way, more precise zoom control can be achieved, and the degree of automation and ease of operation of the camera module 1 can be improved.

[0079] Among them, see Figure 2 , a prism 300 is provided at the light-inlet end, and a photosensitive chip 400 is provided at the light-outlet end. The prism 300 can change the propagation direction of the light at the light-inlet end, especially in the camera module 1 with a periscope design, the prism 300 can turn the light entering in the horizontal direction 90 degrees, so that it propagates along the optical axis direction of the lens 100, so that the telephoto zoom function can be achieved without increasing the thickness of the device, meeting the design requirements of modern electronic devices for light and thinness. The photosensitive chip 400 is located at the light-outlet end, responsible for receiving the light processed by the lens 100 and the prism 300, and converting it into Electrical signals, these electrical signals are subsequently processed and encoded to eventually form an image. That is to say, the prism 300 and the photosensitive chip 400 cooperate with each other in the optical system to jointly determine the quality and effect of the imaging. The prism 300 provides suitable light conditions for the photosensitive chip 400 by steering and preliminarily processing the light, and the photosensitive chip 400 converts the light into electrical signals to capture and record the image. For example, in a low-light environment, the prism 300 can enhance the sensitivity of the photosensitive chip 400 by increasing the amount of light entering, thereby obtaining a clearer and brighter image.

[0080] An embodiment of the present application further provides an electronic device, which includes the camera module 1 in any one of the above embodiments.

[0081] The electronic device may be any electronic device such as a smart phone, a digital camera, a tablet computer or a drone.

[0082] In addition, the camera module in the embodiment of the present application can have the same structure as the camera module 1 in the above embodiment and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiment, and the embodiment of the present application will not be repeated here.
