Abstract
Description
Technical Field
[0001] This application belongs to the field of photography technology, specifically relating to a camera module and electronic device. Background Technology
[0002] In existing telephoto camera modules, in order to improve the optical magnification, one approach is to use a telephoto camera for digital zoom, and another approach is to add a telephoto camera module with an even longer focal length. The former approach results in a decrease in image clarity due to digital zoom, while the latter approach increases the number of cameras, occupies more stacking space, and makes electronic devices thicker and heavier, affecting the user experience. Utility Model Content
[0003] This application aims to provide a camera module and electronic device that solves the problems of decreased image clarity and increased bulkiness caused by increasing optical magnification.
[0004] To solve the above-mentioned technical problems, this application is implemented as follows:
[0005] In a first aspect, embodiments of this application propose a camera module, comprising:
[0006] The shooting component includes a light path conversion structure, a focusing lens, and a photosensitive chip arranged in sequence. Light is converted by the light path conversion structure, passes through the focusing lens, and is transmitted to the photosensitive chip for imaging.
[0007] The zoom assembly includes a zoom carrier, a first lens group having a first focal length, and a second lens group having a second focal length. The first lens group and the second lens group are spaced apart on the zoom carrier along a first direction. The zoom carrier moves relative to the optical path conversion structure along the first direction. Light rays passing through the first lens group or the second lens group are directed to the light-incident surface of the optical path conversion structure to switch the shooting mode of the camera module.
[0008] Secondly, embodiments of this application provide an electronic device, including:
[0009] shell;
[0010] Camera modules, such as the camera modules mentioned above;
[0011] The camera module is assembled with the housing.
[0012] In this embodiment, a zoom component is added. Since the zoom component includes a first lens group with a first focal length and a second lens group with a second focal length, under the drive of the zoom carrier, light passing through the first lens group can be directed through the first light-transmitting hole to the light-incident surface of the optical path conversion structure, enabling the camera module to achieve zoom in the first focal length. Alternatively, light passing through the second lens group can be directed through the first light-transmitting hole to the light-incident surface of the optical path conversion structure, enabling the camera module to achieve zoom in the second focal length. The camera module in this embodiment can achieve zoom in both the first and second focal lengths, effectively improving the optical focusing capability of the camera module and ensuring image clarity and quality. Furthermore, by adding the zoom component, the structure is simple, occupies less stacking space, avoids bulky electronic devices, and helps ensure a better user experience.

[0044] The following is combined with Figures 1-18 This application describes the camera module and electronic device.
[0045] like Figures 1 to 6 As shown, the camera module 100 includes: a shooting component 10, which includes a light path conversion structure 13, a focusing lens 11, and a photosensitive chip 12 arranged sequentially. Light is converted by the light path conversion structure 13, passes through the focusing lens 11, and is transmitted to the photosensitive chip 12 for imaging; and a zoom component 20, which includes a zoom carrier 22, a first lens group 23 having a first focal length, and a second lens group 24 having a second focal length. The first lens group 23 and the second lens group 24 are spaced apart on the zoom carrier 22 along a first direction. The zoom carrier 22 moves relative to the light path conversion structure 13 along the first direction. Light passing through the first lens group 23 or the second lens group 24 is incident on the light-incident surface of the light path conversion structure 13 through the first light-transmitting hole 2111 to switch the shooting mode of the camera module 100.
[0046] In this embodiment, a zoom component 20 is added. Since the zoom component 20 includes a first lens group 23 with a first focal length and a second lens group 24 with a second focal length, driven by the zoom carrier 22, light passing through the first lens group 23 can be directed through the first light-transmitting hole 2111 to the light-incident surface of the light path conversion structure 13, enabling the camera module 100 to achieve zoom in the first focal length; alternatively, light passing through the second lens group 24 can also be directed through the first light-transmitting hole 2111 to the light-incident surface of the light path conversion structure 13, enabling the camera module 100 to achieve zoom in the second focal length. The camera module 100 in this embodiment can achieve zoom in both the first and second focal lengths, effectively improving the optical focusing capability of the camera module 100 and ensuring image clarity and quality. Furthermore, in this embodiment, by adding the zoom component 20, the structure is simple, occupying less stacking space, avoiding bulky electronic devices, and contributing to a better user experience.
[0047] In this embodiment of the application, the camera module 100 may include a shooting component 10, and the focusing lens 11 in the shooting component 10 may be an autofocus (AF) lens. The shooting component 10 may also include an autofocus sensor. The AF lens can detect the distance between the subject and the lens according to the autofocus sensor and automatically adjust the focal length of the lens so that the subject forms a clear image on the image plane of the photosensitive chip 12.
[0048] Specifically, the photosensitive chip 12 is a semiconductor device that converts light into electrical signals, and is an important component of the camera module 100. When light shines on the photosensitive chip 12, the photosensitive elements in the chip absorb photon energy, exciting electrons and generating electrical signals. These electrical signals are then transmitted to the signal processing circuit, where they are amplified, converted from analog to digital, and finally converted into digital image signals. The photosensitive chip 12 can be of the type of charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS).
[0049] Specifically, the photosensitive chip 12 can be disposed on the light-emitting side of the focusing lens 11. The photosensitive chip 12 can be arranged corresponding to the light-emitting surface of the focusing lens 11. In some embodiments, the photosensitive chip 12 can be arranged opposite to the light-emitting surface of the focusing lens 11 so that the light collected by the focusing lens 11 can be transmitted to the photosensitive chip 12 for imaging. In other embodiments, the shooting assembly 10 can also include a rear reflector, which can be disposed between the photosensitive chip 12 and the focusing lens 11. The rear reflector can change the path of light so that the light collected by the focusing lens 11 can be transmitted to the photosensitive chip 12 for imaging. Moreover, it can also extend the light transmission path, which facilitates the realization of telephoto function and miniaturization design of the camera module 100. Specifically, the rear reflector can be a mirror or a prism, etc.
[0050] In some embodiments, the shooting assembly 10 may further include an optical path conversion structure 13 for converting light paths. The optical path conversion structure 13 may be disposed between the zoom carrier 22 and the focusing lens 11. The light-incident surface of the optical path conversion structure 13 may be disposed opposite to the first lens group 23 or the second lens group 24, and the light-exit surface of the optical path conversion structure 13 may be disposed opposite to the light-incident surface of the focusing lens 11.
[0051] In this embodiment, the light path conversion structure 13 can serve as a front reflector to change the path of light, thereby ensuring that the light collected by the first lens group 23 or the second lens group 24 is transmitted to the focusing lens 11. Furthermore, it can also extend the light transmission path, making it easier for the camera module 100 to achieve telephoto functionality and miniaturization.
[0052] Specifically, the optical path conversion structure 13 can be a reflector or a prism, etc.
[0053] Specifically, the camera module 100 may include a first direction, a second direction, and a third direction that intersect each other, wherein the first direction and the second direction may be perpendicular or approximately perpendicular, the first direction and the third direction may be perpendicular or approximately perpendicular, and the second direction and the third direction may be perpendicular or approximately perpendicular. Figure 1 As shown, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction.
[0054] Specifically, the camera module 100 further includes a zoom assembly 20, which includes a first lens group 23 and a second lens group 24. The first lens group 23 and the second lens group 24 are arranged at intervals along a first direction on the zoom carrier 22. Since the zoom carrier 22 can move relative to the optical path conversion structure 13 along the first direction, the zoom carrier 22 can drive the first lens group 23 and the second lens group 24 to move synchronously along the first direction.
[0055] In some embodiments, the zoom assembly 20 further includes a base 21, and the zoom carrier 22 can be movably connected to the base 21 along a first direction.
[0056] Specifically, the base 21 includes a base plate 211, which can be disposed between the zoom assembly 20 and the shooting assembly 10. The base plate 211 is provided with a first light-transmitting hole 2111. In this way, the first lens group 23 and the second lens group 24 can change positions under the drive of the zoom carrier 22, so that the first lens group 23 or the second lens group 24 can be opposite to the first light-transmitting hole 2111, thereby realizing the switching of the shooting mode of the camera module 100.
[0057] In other embodiments, the shooting component 10 may include a base 15, which may be provided with a third light-transmitting hole 154. The zoom carrier 22 may be movably connected to the base 15. In this way, the first lens group 23 and the second lens group 24 can change positions under the drive of the zoom carrier 22, so that the first lens group 23 or the second lens group 24 can be opposite to the third light-transmitting hole 154.
[0058] Furthermore, the camera module 100 can have a first shooting mode and a second shooting mode. In the first shooting mode, the first lens group 23 can be arranged opposite to the first light-transmitting hole 2111, so that the light collected by the first lens group 23 can be directed onto the light-incident surface of the light path conversion structure 13, enabling the camera module 100 to achieve shooting at a first focal length. In the second shooting mode, the second lens group 24 can be arranged opposite to the first light-transmitting hole 2111, so that the light collected by the second lens group 24 can be directed onto the light-incident surface of the light path conversion structure 13, enabling the camera module 100 to achieve shooting at a second focal length. The camera module 100 can switch between the first shooting mode and the second shooting mode, enabling the camera module 100 to simultaneously achieve two optical zooms, which can improve the zoom performance of the camera module 100 and enrich the application scenarios of the camera module 100.
[0059] Currently, in optical imaging systems, the coordinated operation of the optical path conversion structure and the lens is crucial for achieving high-quality imaging. As a reversing and reflecting component, the alignment of the optical path conversion structure with the lens's optical center directly determines the performance of the optical system. When their optical centers are aligned, light can propagate precisely along a predetermined path, reducing aberrations and improving image sharpness, color reproduction, and focusing accuracy, thereby significantly enhancing optical performance.
[0060] From an optical perspective, light rays refract and reflect according to the law of reflection when passing through a lens. If the light path conversion structure is not aligned with the lens's optical center, the light's propagation path will deviate from the ideal state. For example, in a camera's viewfinder system, if the prism light path conversion structure deviates from the lens's optical center, the viewfinder image may appear blurry or distorted, making it difficult for the photographer to accurately judge the shooting effect.
[0061] However, due to the limitations of the mechanical structure, when the optical path conversion structure is used as a movable deflection component, it will inevitably tilt during movement. Once the optical path conversion structure tilts, the reflection angle of the light will change, and the light rays that originally travel along the optical axis of the lens will be deflected. This deflection will not only introduce aberrations such as coma and astigmatism, but also cause uneven distribution of light on the image sensor, resulting in problems such as blurred edges and vignetting, and ultimately leading to a significant decrease in optical performance.
[0062] In this embodiment, different optical zooms can be achieved by adjusting the positions of the first lens group 23 and the second lens group 24. The optical centers of all components in the imaging assembly 10 can be aligned, which is beneficial for improving the optical performance of the camera module 100. Both the front reflector and the rear reflector can be fixedly connected to the base 15, ensuring that the optical centers of the front reflector, focusing lens 11, rear reflector, and image sensor 12 are aligned. That is, the optical centers of the front reflector, focusing lens 11, rear reflector, and image sensor 12 are on the same optical axis, which improves imaging reliability. Taking the focusing lens 11 as an example, the optical center of the focusing lens 11 refers to its optical center point, which is the center point where light converges or disperses.
[0063] In this embodiment, the focal length of the focusing lens 11 can be f1, the first focal length f2 of the first lens group 23 can be A times f1, that is, the first focal length f2 satisfies: f2=A*f1, and the second focal length f3 of the second lens group 24 can be B times f1, that is, the second focal length f3 satisfies: f3=B*f1. f1 can be 23mm, 24mm, 26mm, 30mm, or 35mm, etc., and A and B can both be natural numbers greater than 1. A and B are different so that the camera module 100 can realize two optical zooms. In one specific embodiment, the focal length f1 of the focusing lens 11 is 23mm, A is 3, B is 5, the corresponding first focal length f2 can be 69mm, and the second focal length f3 can be 115mm.
[0064] Specifically, the base 21 can be the main structure of the zoom assembly 20. The zoom assembly 20 can be assembled with the shooting assembly 10 through the base 21. The base 21 can also be used to support and mount the zoom carrier 22. The zoom carrier 22 can be used to support and mount the first lens group 23 and the second lens group 24. The zoom carrier 22 can be provided with a first mounting hole 223 and a second mounting hole 224. The first lens group 23 can be installed in the first mounting hole 223, and the second lens group 24 can be installed in the second mounting hole 224. The conduction direction of the first mounting hole 223, the optical axis direction of the first lens group 23, the conduction direction of the second mounting hole 224, and the optical axis direction of the second lens group 24 are all the same as the conduction direction of the first light-transmitting hole 2111. In the first shooting mode, the first mounting hole 223 can be set opposite to the first light-transmitting hole 2111. In the second shooting mode, the second mounting hole 224 can be set opposite to the first light-transmitting hole 2111.
[0065] Specifically, in this embodiment, the number and type of lenses in the first lens group 23 are not specifically limited, nor are the number and type of lenses in the second lens group 24.
[0066] Specifically, the first light-transmitting hole 2111 can be circular or polygonal. In this embodiment, the shape and size of the first light-transmitting hole 2111 are not specifically limited and can be designed according to actual needs.
[0067] Optionally, the base 21 includes a base plate 211, which is disposed between the shooting component 10 and the zoom carrier 22. The base plate 211 is provided with a first light-transmitting hole 2111, through which light passing through the first lens group 23 or the second lens group 24 is directed to the light-incident surface of the light path conversion structure 13. A first guide member 214 is provided on the side of the base plate 211 facing the zoom carrier 22, and a second guide member 221 corresponding to the first guide member 214 is provided on the zoom carrier 22. The second guide member 221 and the first guide member 214 slide in a first direction.
[0068] In this embodiment, the first guide member 214 and the second guide member 221 slide in a first direction, which can improve the reliability and stability of the zoom carrier 22 driving the first lens group 23 and the second lens group 24 to move.
[0069] Specifically, the number of the first guide member 214 and the second guide member 221 may be the same or different.
[0070] In some embodiments, the number of first guide members 214 may include at least two. These at least two first guide members 214 may be symmetrically arranged on opposite sides of the first light-transmitting hole 2111 in a second direction, where the second direction intersects the first direction. This improves the uniformity of force distribution on the zoom carrier 22 and ensures the reliability and stability of the zoom carrier 22 sliding relative to the base 21 along the first direction. Specifically, the at least two first guide members 214 located on the same side of the first light-transmitting hole 2111 in the second direction may be arranged at intervals along the first direction.
[0071] Similarly, the number of second guide members 221 can be at least two. These at least two second guide members 221 can be symmetrically arranged on opposite sides of the first light-transmitting hole 2111 in the second direction. The second direction intersects the first direction, which can improve the uniformity of force on the zoom carrier 22 and ensure the reliability and stability of the zoom carrier 22 sliding relative to the base 21 along the first direction. Specifically, the at least two second guide members 221 located on the same side of the first light-transmitting hole 2111 in the second direction can be arranged at intervals along the first direction.
[0072] Specifically, the structures of the first guide member 214 and the second guide member 221 can be adapted.
[0073] In some optional embodiments, the first guide member 214 is a slide rail extending along a first direction, and the second guide member 221 is a slider. The slider can slide and engage with the slide rail along the first direction, which can also reduce the sliding friction between the first guide member 214 and the second guide member 221, so as to ensure the reliability and stability of the sliding engagement between the first guide member 214 and the second guide member 221.
[0074] In some optional embodiments, the first guide member 214 is a guide rod extending along a first direction, and the second guide member 221 is a groove, so that the guide rod can slide with the groove, which can reduce the sliding friction between the first guide member 214 and the second guide member 221, and facilitate the reliability and stability of the sliding engagement between the first guide member 214 and the second guide member 221.
[0075] Optionally, the shape of the cross-section of the groove perpendicular to the first direction includes one of U-shape, V-shape, and arc shape, which can improve the structural diversity of the groove.
[0076] Specifically, the shapes of the second guide members 221 arranged at different positions on the zoom carrier 22 can be different, such as... Figure 7 and Figure 8 As shown, the bottom of the zoom carrier 22 is provided with four support feet, and the support feet are provided with second guide members 221. The second guide member 221 on the left side of the zoom carrier 22 is a U-shaped groove, and the second guide member 221 on the right side of the zoom carrier 22 is a V-shaped groove. Alternatively, it can be designed that the second guide member 221 on the right side of the zoom carrier 22 is a U-shaped groove, and the second guide member 221 on the left side of the zoom carrier 22 is a V-shaped groove. In this way, the shapes of the second guide members 221 on the two sides of the zoom carrier 22 are different, so that the sliding friction between the two sides of the zoom carrier 22 and the base 21 is different, which makes it easier to ensure that the zoom carrier 22 slides more stably along the first direction.
[0077] Specifically, such as Figure 9 As shown, the corresponding base plate 211 has limiting grooves 2112 on both sides along the second direction, and the two guide rods are at least partially embedded in the limiting grooves 2112, so that the zoom carrier 22 can slide along the first direction with less resistance through the two guide rods, which can greatly reduce the required driving force.
[0078] In some alternative embodiments, the base 21 may further include a surrounding plate 212 and a top plate 213. One end of the surrounding plate 212 is connected to the circumferential side of the top plate 213, and the other end is connected to the circumferential side of the bottom plate 211. The top plate 213 is provided with a second light-transmitting hole 2131 opposite to the first light-transmitting hole 2111. The top plate 213, the surrounding plate 212, and the bottom plate 211 enclose and form an accommodating space, and the zoom carrier 22 is disposed in the accommodating space.
[0079] In this embodiment, a receiving space can be formed by using a top plate 213, a surrounding plate 212, and a bottom plate 211. By placing the zoom carrier 22 within the receiving space, the first lens group 23 and the second lens group 24 can be protected within the receiving space.
[0080] In some embodiments, the base plate 211 and the enclosure plate 212 can be integrally formed, and the enclosure plate 212 can be spliced and fixed to the top plate 213. In other embodiments, the base plate 211 and the enclosure plate 212 can be spliced and fixed, and the enclosure plate 212 and the top plate 213 can be integrally formed. Specifically, the base 21 is generally rectangular in shape.
[0081] Specifically, the second light-transmitting aperture 2131 can be used to transmit external light. In the first shooting mode, external light can pass through the second light-transmitting aperture 2131, the first lens group 23, the first light-transmitting aperture 2111, and the focusing lens 11 in sequence, and then be transmitted to the image sensor 12, wherein the second lens group 24 can be hidden; in the second shooting mode, external light can pass through the second light-transmitting aperture 2131, the second lens group 24, the first light-transmitting aperture 2111, the light path conversion structure 13, and the focusing lens 11 in sequence, and then be transmitted to the image sensor 12, wherein the first lens group 23 can be hidden.
[0082] Specifically, the second light-transmitting hole 2131 can be a circular hole or a square hole, etc. In this embodiment of the application, the shape and size of the second light-transmitting hole 2131 are not specifically limited.
[0083] In some alternative embodiments, a first coil 215 is provided on the side of the base 21 facing the zoom carrier 22, and a first magnet 222 is provided on the side of the zoom carrier 22 facing the base 21. The first coil 215 and the first magnet 222 are at least partially opposite to each other along a second direction. When the first coil 215 is energized, it drives the first magnet 222 to move along a first direction. The second direction intersects with the first direction.
[0084] In this embodiment, the zoom carrier 22 can be driven by the cooperation of the first coil 215 and the first magnet 222, which is relatively simple and convenient.
[0085] Specifically, the first coil 215 and the first magnet 222 can cooperate with each other, such as Figures 8 to 10 As shown, the first coil 215 is arranged on the right side of the base 21, and the corresponding first magnet 222 is arranged on the right side of the zoom carrier 22; the first coil 215 is arranged on the left side of the base 21, and the corresponding first magnet 222 is arranged on the left side of the zoom carrier 22.
[0086] Specifically, the first coil 215 can also be arranged on both sides of the base 21 in the second direction, i.e., the left and right sides, so that the zoom carrier 22 can achieve dual-sided driving. Alternatively, the first coil 215 can be arranged only on one side of the base 21 in the second direction, i.e., the left or right side, so that the zoom carrier 22 can achieve single-sided driving, which is beneficial to reducing the size of the camera module 100.
[0087] Specifically, a first receiving groove 2121 may be provided on the inner side of the enclosure plate 212 to receive the first coil 215. A second receiving groove may be provided on the outer side of the zoom carrier 22 to receive the first magnet 222.
[0088] Specifically, the camera module 100 may further include a first flexible circuit board 31, and the first coil 215 may be connected to the first flexible circuit board 31 to enable power supply.
[0089] In some embodiments, the first light-transmitting hole 2111 may be positioned opposite to the light-incident surface of the focusing lens 11.
[0090] Specifically, in this embodiment, the number of the first coil 215 and the first magnet 222 can be arranged according to the driving force requirements.
[0091] Optionally, there may be multiple first magnets 222, including at least two target magnets. The at least two target magnets are located on the same side of the zoom carrier 22 in the second direction. The magnetic poles of the at least two target magnets facing the first coil are arranged alternately with the N pole and the S pole along the first direction. That is, the at least two first magnets 222 located on the same side of the zoom carrier 22 in the second direction can be arranged alternately with the N pole and the S pole facing the first coil 215 in the first direction, so that the force direction of the first magnets 222 is the same, which makes it easier to ensure the driving of the zoom carrier 22.
[0092] like Figure 10As shown, several first coils 215 are arranged in parallel, and several first magnets 222 are arranged in a strip. The four first coils 215 on the left side of the base 21 are designated as first coil 215-1, first coil 215-2, first coil 215-3, and first coil 215-4; the other four first coils 215 are designated as first coil 215-5, first coil 215-6, first coil 215-7, and first coil 215-8. First coils 215-1 and 215-5 are arranged opposite each other along a second direction; first coils 215-2 and 215-6 are arranged opposite each other along a second direction; first coils 215-3 and 215-7 are arranged opposite each other along a second direction; and first coils 215-4 and 215-8 are arranged opposite each other along a second direction. Taking the two first magnets 222-1 and 222-2 on the left side of the first zoom carrier 22 and the two first magnets 222-3 and 222-4 on the right side of the zoom carrier 22 as examples, the first magnets 222-1 and 222-3 are arranged opposite each other along the second direction, and the first magnets 222-2 and 222-4 are also arranged opposite each other along the second direction. The N poles of the first magnets 222-1 and 222-3 face the first coil 215, and the S poles of the first magnets 222-2 and 222-4 face the first coil 215.
[0093] Specifically, after the first coil 215 is energized, a magnetic field is generated, which drives the first magnet 222 to move the zoom carrier 22 along the positive or negative direction of the first direction, thereby realizing the change of optical focal length. Specifically, the first coils 215-1 and 215-5 are energized simultaneously, followed by the first coils 215-2 and 215-6, then the first coils 215-3 and 215-7, and finally the first coils 215-4 and 215-8. This sequential energization generates an induced magnetic field. The first magnet 222, under the influence of this induced magnetic field, generates a driving force along the positive direction of the first direction, allowing the zoom carrier 22 to drive the first lens group 23 and the second lens to move along the positive direction of the first direction. This allows the first lens group 23 to be aligned with the first light-transmitting aperture 2111. The camera module 100 can be switched to the first shooting mode to achieve shooting at the first focal length; conversely, when the first coil 215 is energized in the reverse direction, the first coils 215-4 and 215-8 are energized simultaneously, the first coils 215-3 and 215-7 are energized simultaneously, the first coils 215-2 and 215-6 are energized simultaneously, and the first coils 215-1 and 215-5 are energized simultaneously, which generates a driving force in the negative direction of the first direction, so that the second lens group 24 can be opposite to the first light-transmitting hole 2111, and the camera module 100 can be switched to the second shooting mode to achieve shooting at the second focal length.
[0094] Specifically, the base 21 can be an in-mold injection (IM) structure, with multiple metal wires embedded inside, such as... Figures 11 to 13 As shown, the first coil 215 can be soldered to the metal circuit through the solder pad 32 to conduct electricity, so as to be connected to the first flexible circuit board 31 through the metal circuit to realize current driving.

[0096] Optionally, the base 15 is connected to the side of the base 21 away from the zoom carrier 22, which can enable the assembly between the shooting component 10 and the zoom component 20.

[0098] In this embodiment, light passing through the first lens group 23 or the second lens group 24 can pass through the third light-transmitting hole 154 and then be incident on the light-incident surface of the light path conversion structure 13, ensuring the reliability of imaging.
[0099] Specifically, the shape of the third light-transmitting hole 154 may be the same as or different from the shape of the first light-transmitting hole 2111. The third light-transmitting hole 154 may be a circular hole or a square hole, etc. In this embodiment, the shape and size of the third light-transmitting hole 154 are not specifically limited.

[0108] In some embodiments, the third guide 155 is a slide rail extending along the optical axis of the focusing lens 11, and the fourth guide is a slider. The slider is slidably connected to the slide rail along the optical axis of the focusing lens 11, which can reduce the sliding friction between the focusing carrier 16 and the second receiving part 152, and effectively ensure the reliability of the focusing carrier 16 driving the focusing lens 11 to move along the optical axis of the focusing lens 11.
