Description

Technical Field

[0001] The present invention relates to the field of image shooting technology, and in particular to a lens module and electronic equipment. Background Art

[0002] Currently, electronic devices such as mobile phones, computers, and notebooks are usually equipped with lens modules to facilitate people's activities such as shooting and video chatting through mobile phones, computers, and notebooks. Among them, the lens module includes a lens, which is one of the important components in the lens module for optical imaging. There are many types of lenses. Based on the focal length, they can be divided into short-focus lenses, medium-focus lenses, and long-focus lenses; based on the change in focal length, they can be divided into fixed-focus lenses and zoom lenses. Among them, to achieve zoom in the lens module, the industry mainly uses multiple lenses and switches between multiple lenses to achieve zoom. That is, currently, it is standard to set three or more lens modules in electronic devices, resulting in a larger overall size and higher cost of the electronic devices. Then, in order to reduce costs, another zoom solution has emerged in the industry, that is, setting the lens in the lens module as a manual zoom lens, and achieving zoom through manual focus adjustment.

[0003] When the lens in the lens module is a manual zoom lens, when shooting through the lens module is required, the user needs to manually adjust the focus of the lens. However, when the user manually adjusts the focus of the lens, it is usually judged by the changes in the camera image whether the focus is adjusted in place, and the feel of adjusting the focus hardly changes, resulting in the user being unable to judge whether the desired focal length position is adjusted based on the change in the feel. Therefore, in the process of manual focus adjustment, it is easy to fail to rotate in place or rotate excessively. The user usually needs to make multiple adjustments before adjusting to the desired focal length. The focus adjustment is cumbersome and time-consuming, resulting in a poor user experience. Summary of the Invention

[0004] The embodiments of the present application disclose a lens module and an electronic device, which can make the lens module have a significant change in feel when manually adjusted to a certain focal length, thereby shortening the user's adjustment time for the focal length of the lens module and improving the user's experience.

[0005] To achieve the above objectives, in a first aspect, embodiments of the present application disclose a lens module, comprising:

[0006] Base sleeve;

[0007] a lens module, the lens module being slidably disposed on the base sleeve along an optical axis direction of the lens module, and the lens module being provided with an insertion portion;

[0008] The rotating sleeve is covered by the lens module and is rotatably connected to the base sleeve around the optical axis. The top of the rotating sleeve is provided with a first light hole coaxial with the optical axis, and the wall of the rotating sleeve is provided with a first slide groove spirally extending along the wall toward the top of the rotating sleeve. The first slide groove includes a plurality of slide groove sections connected in sequence, and the slopes of at least two of the plurality of slide groove sections are different from each other. The insertion portion is slidably inserted into the first slide groove along the extension direction of the first slide groove, so that when the rotating sleeve rotates, the lens module can be driven to move along the optical axis direction through the insertion portion and the first slide groove.

[0009] In this embodiment, a rotating sleeve is provided over the lens module and is rotatably connected to the base sleeve about an optical axis. A first light hole coaxial with the optical axis is provided on the top of the rotating sleeve, so that external light can enter the lens module through the first light hole to be converged on the lens module and form an image. A first slide groove is provided on the wall of the rotating sleeve, extending spirally along the wall toward the top of the rotating sleeve. The first slide groove includes a plurality of slide groove sections connected in sequence. An insert portion is slidably inserted into the first slide groove along the extension direction of the first slide groove. When the rotating sleeve rotates relative to the base sleeve about the optical axis, the insert portion slides along the extension direction of the first slide groove to drive the lens module to slide relative to the base sleeve along the optical axis, so that the lens module can move along the optical axis, so that the lens module can adjust the focal length by rotating the rotating sleeve, and the image captured by the lens module can be clear.

[0010] In addition, the first slide groove includes a plurality of slide groove sections connected in sequence, and the slopes of at least two of the plurality of slide groove sections are different from each other. The insertion part is slidably inserted into the first slide groove along the extension direction of the first slide groove, so that when the rotating sleeve rotates, the lens module can be driven to move along the optical axis direction through the cooperation between the insertion part and the first slide groove, that is, the rotating sleeve is rotated, and the groove wall of the first slide groove on the rotating sleeve can squeeze the insertion part to slide along the extension direction of the first slide groove. When the insertion part slides in the slide groove sections with different slopes, on the one hand, different friction resistances can be generated between the insertion part and the groove wall of the slide groove section, so that the force for rotating the rotating sleeve is different, so that the user can rotate the rotating sleeve. The rotating sleeve can have different hand feelings when rotating; on the other hand, when the user rotates the rotating sleeve, a step difference feeling is generated when the insertion part slides in the slide groove sections with different slopes, so that the change in the user's hand feeling when rotating the rotating sleeve is more obvious, thereby reminding the user that the lens module is adjusted to a certain focal length. Compared with the first slide groove being composed of slide groove sections with the same slope, the user needs to judge whether to adjust the lens module to the focal length by observing the changes in the captured image, which causes the user to repeatedly rotate the rotating sleeve for multiple times to successfully focus. This method can effectively shorten the user's adjustment time for the focal length of the lens module and improve the user's experience.

[0011] In a possible implementation of the first aspect, the multiple chute sections include multiple first chute sections and multiple second chute sections, the multiple first chute sections and the multiple second chute sections are arranged at intervals, the first chute section extends along the circumference of the rotating sleeve, the second chute section is arranged on the rotating sleeve at an angle to the first chute section, and the angle at the connection between the first chute section and the second chute section is an obtuse angle.

[0012] Therefore, when the insertion part slides from the first slide groove section into the second slide groove section, or slides from the second slide groove section into the first slide groove section, the change in friction resistance between the insertion part and the first slide groove can be relatively obvious, and the step difference between the first slide groove section and the second slide groove section is also relatively obvious, so that the user can clearly feel the change in hand feel, and the reminder to the user that the lens module has been adjusted to a certain focal length position is more obvious.

[0013] In a possible implementation of the first aspect, a guide member is provided on the side of the base sleeve facing the lens module, and a second slide groove extending along the optical axis direction is provided on the guide member. The insertion portion is sequentially inserted into the second slide groove and the first slide groove, and the insertion portion is slidably connected to the second slide groove along the extension direction of the second slide groove.

[0014] By sequentially inserting the insertion portion into the second slide groove and the first slide groove, when the rotating sleeve is rotated to drive the insertion portion to slide along the first slide groove, the insertion portion also slides along the extension direction of the second slide groove at the same time. That is, rotating the rotating sleeve can drive the insertion portion to slide along the optical axis, so that the insertion portion can drive the lens module to move along the optical axis, so that the lens module can always be located in the light path reflected by the scene, so that the lens module can focus under the drive of the insertion portion.

[0015] In a possible implementation of the first aspect, the insertion portion is a sliding shaft, and there are multiple sliding shafts, and the multiple sliding shafts are evenly distributed on the lens module around the optical axis. There are multiple first sliding grooves and multiple second sliding grooves, and the multiple first sliding grooves and multiple second sliding grooves correspond one-to-one to the multiple sliding shafts.

[0016] This reduces the contact area between the insertion portion and the walls of the first and second chute slots, minimizing frictional resistance during sliding. Furthermore, all parts of the lens module around the optical axis can be moved simultaneously via the sliding shaft, resulting in smoother, more secure, and more labor-saving movement.

[0017] In a possible implementation of the first aspect, the guide member is a tubular structure extending toward the lens module, the tubular structure has a lumen, the lens module can be slidably accommodated in the lumen, and the second slide groove is opened on the wall of the tubular structure and connected to the lumen.

[0018] Thus, the lens module can move along the optical axis in the tube cavity of the tubular structure, so that while the lens module can realize movement along the optical axis by sliding the insertion part in the first slide groove and the second slide groove, it can also be restricted by the tube wall of the tubular structure from moving in a direction perpendicular to the optical axis, so that the lens module can only move along the optical axis, thereby making the focal point of the lens module always on the light path reflected by the scene, thereby making the adjustment of the focal length of the lens module simple and quick.

[0019] In a possible implementation of the first aspect, the lens module further includes:

[0020] an outer sleeve, the outer sleeve being sleeved on the outside of the rotating sleeve, the top of the outer sleeve being provided with a second light-passing hole coaxial with the optical axis, the outer sleeve being fixedly connected to the base sleeve and rotatably connected to the rotating sleeve around the optical axis, the rotating sleeve being located between the outer sleeve and the base sleeve;

[0021] A shift assembly, wherein the outer sleeve is rotatably connected to the rotating sleeve around the optical axis through the shift assembly.

[0022] Thus, the outer sleeve can have a protective effect on the rotating sleeve, preventing foreign matter such as dust and fibers from entering the rotating sleeve and affecting the rotation of the rotating sleeve. In addition, the outer sleeve is rotatably connected to the rotating sleeve around the optical axis via the shift assembly, so that when the insertion portion slides along two slide groove sections with different slopes, the friction between the outer sleeve and the rotating sleeve is different. This can make the force required to rotate the rotating sleeve different when the insertion portion slides along the two slide groove sections with different slopes, so that the user will have a different feel when rotating the rotating sleeve, thereby allowing the user to adjust the focal length of the lens module more quickly, thereby providing the user with a better user experience.

[0023] In a possible implementation of the first aspect, the shift assembly includes:

[0024] a first shifting member, the first shifting member being disposed on the rotating sleeve;

[0025] a second shifting member, the second shifting member being disposed on the outer sleeve;

[0026] an abutment drive assembly, the abutment drive assembly being provided on the rotating sleeve and / or the outer sleeve, the abutment drive assembly being used to provide a force for the rotating sleeve to bear against the outer sleeve, so as to generate friction when the rotating sleeve rotates relative to the outer sleeve;

[0027] When the insertion portion slides in one of the multiple sliding groove sections, the first stop member and the second stop member are opposite to each other along the optical axis direction, and a first friction force exists between the outer sleeve and the rotating sleeve. When the insertion portion slides in another sliding groove section with a different slope among the multiple sliding groove sections, the first stop member and the second stop member are staggered along the optical axis direction, and a second friction force exists between the outer sleeve and the rotating sleeve, and the first friction force and the second friction force are different from each other.

[0028] When the insertion portion slides in different slide groove sections, the relative positions of the first gear member and the second gear member along the optical axis direction change, so that the sliding contact area between the outer sleeve and the rotating sleeve changes, thereby generating different first friction forces and second friction forces between the outer sleeve and the rotating sleeve, so that the feel of rotating the rotating sleeve can be changed, and this change does not require additional operation. The different feel can be produced by rotating the rotating sleeve, and the operation is simple and convenient.

[0029] In a possible implementation of the first aspect,

[0030] The first shifting member is a protruding member, which protrudes from the rotating sleeve and faces the outer sleeve;

[0031] The second shifting member is a groove recessed in a direction away from the rotating sleeve. When the inserting portion slides in one of the multiple chute sections, the protruding member is located in the groove. When the inserting portion slides in another chute section with a different slope among the multiple chute sections, the protruding member is located outside the groove.

[0032] Therefore, when the rotating sleeve is rotated, the protrusion can slide into the groove and slide in the groove, so that the rotating sleeve and the outer sleeve are in direct contact and rotationally connected to form a first friction force, and the protrusion can also slide out of the groove, the protrusion contacts and rotates with the outer sleeve, so that a second friction force is formed between the rotating sleeve and the outer sleeve, so that the contact area of the rotational connection between the rotating sleeve and the outer sleeve can have a more obvious change, so that the first friction force and the second friction force can have a significant difference, so that the feel of rotating the rotating sleeve has a significant change, and the structures of the first gear member and the second gear member are simple and easy to implement.

[0033] In a possible implementation of the first aspect, there are multiple grooves, and the multiple grooves are arranged on the outer sleeve at intervals along the circumference of the outer sleeve, and the multiple grooves are located on the same circle perpendicular to the optical axis, and the protrusion can slide between the multiple grooves.

[0034] A plurality of grooves are arranged on the outer sleeve at intervals along the circumference of the outer sleeve, and the plurality of grooves are located on the same circle perpendicular to the optical axis. The protruding member slides between the plurality of grooves, so that each groove corresponds to a focal length position, so that the lens module can have a plurality of focal length positions that are easy to adjust into place, thereby enabling the lens module to quickly and clearly capture scenes at different distances.

[0035] In a possible implementation of the first aspect, a guiding portion is provided on the groove wall of adjacent grooves, and a blocking portion is provided on the groove wall of the first groove. The first groove is a groove located at both ends of the multiple grooves, and the blocking portion is opposite to the guiding portion provided on the groove wall of the first groove.

[0036] Therefore, by arranging guiding portions on the groove walls of adjacent grooves, the protruding piece can smoothly slide out of one groove and slide into the other groove. At the same time, the rotating sleeve can also be smoothly abutted toward the outer sleeve under the action of the abutment driving assembly, thereby reducing the probability of the rotating sleeve tilting during rotation; blocking portions are provided on the groove walls of the first grooves located at both ends of the multiple grooves, which can prevent the protruding piece from sliding out of the groove combination when sliding into the grooves located at both ends of the multiple grooves, thereby avoiding the slow focusing speed of the lens module caused by the protruding piece sliding out of the groove located at the edge.

[0037] In a possible implementation of the first aspect, a surface of the rotating sleeve provided with the first gear member is further provided with a first protrusion protruding toward the outer sleeve, and / or a surface of the outer sleeve provided with the second gear member is further provided with a second protrusion protruding toward the rotating sleeve. When the first gear member and the second gear member are opposite to each other along the optical axis, the rotating sleeve is rotationally connected to the outer sleeve through the first protrusion and / or the second protrusion. When the first gear member and the second gear member are staggered along the optical axis, the rotating sleeve is rotationally connected to the outer sleeve through the first gear member or the second gear member.

[0038] Therefore, compared with the first friction force generated between the side of the rotating sleeve facing the outer sleeve and the side of the outer sleeve facing the rotating sleeve, the first friction force can be effectively reduced; compared with the second friction force generated between the side of the rotating sleeve facing the outer sleeve and the side of the outer sleeve facing the rotating sleeve, the second friction force can be effectively reduced. In this way, the first friction force and the second friction force to be overcome by rotating the rotating sleeve can be smaller, so that the rotation of the rotating sleeve can be light and smooth, thereby improving the user experience.

[0039] In a possible implementation of the first aspect, the abutment drive assembly includes a first magnetic member and a second magnetic member arranged relative to each other, the first magnetic member is arranged on the side of the rotating sleeve where the first gear member is provided, and the second magnetic member is arranged on the side of the outer sleeve where the second gear member is provided, and the first magnetic member and the second magnetic member provide magnetic force for the rotating sleeve to lean toward the outer sleeve.

[0040] In this way, the rotating sleeve always tends to lean toward the outer sleeve, so that during the rotation of the rotating sleeve, there is always friction between the rotating sleeve and the outer sleeve, which facilitates the change of the magnitude of the friction between the rotating sleeve and the outer sleeve.

[0041] In a possible implementation of the first aspect, the outer sleeve includes a cylinder body and a reinforcement end cover arranged on the light incident side of the cylinder body, the reinforcement end cover is provided with a third light hole coaxial with the optical axis, and the second gear is arranged on the reinforcement end cover.

[0042] In this way, the outer sleeve has better structural strength, and the second gear member is arranged on the reinforced end cover, and the second gear member can be manufactured separately on the reinforced end cover. Compared with the production of the second gear member being arranged on the outer sleeve with a cylindrical body, the production process is simplified.

[0043] In a possible implementation of the first aspect, a second magnet is provided at one end of the outer sleeve located on the light incident side, and the second magnet is used for mounting a polarization filter.

[0044] The polarizing filter can be conveniently mounted on the lens module via the second magnet, so that the lens module can capture images with bright colors.

[0045] In a possible implementation of the first aspect, the lens module further includes:

[0046] A focus ring, which is sleeved on the outside of the outer sleeve and is rotatably connected to the outer sleeve;

[0047] A clamping piece, one end of which is connected to the focus ring, and the other end of which is connected to the rotating sleeve, so as to drive the rotating sleeve to rotate when the focus ring rotates.

[0048] Thus, the rotating sleeve can be driven to rotate by rotating the adjusting ring, which makes the rotating sleeve rotation operation more convenient and comfortable compared to rotating the rotating sleeve by an adjusting shaft connected to the rotating sleeve and protruding from the outer peripheral wall of the outer sleeve.

[0049] In a possible implementation of the first aspect, the outer sleeve is provided with an avoidance groove extending along the circumference of the outer sleeve, and one end of the clamping member is inserted into the avoidance groove and is slidably connected to the avoidance groove;

[0050] The focus ring is provided with a clamping structure, and one end of the clamping member passes through the avoidance groove and is clamped with the clamping structure.

[0051] Therefore, rotating the adjustment ring can drive the clamping part to rotate relative to the outer sleeve, thereby driving the rotating sleeve to rotate, and the clamping part is inserted into the avoidance groove and is slidably connected to the avoidance groove, so that the avoidance groove can limit the rotation of the clamping part to prevent the focusing ring from being rotated too much, causing the first sliding groove on the rotating sleeve to collide with the insertion part, thereby causing the lens module to shake.

[0052] In a possible implementation of the first aspect, a third magnet and a lower cover are provided at one end of the base sleeve away from the lens, the third magnet is provided between the base sleeve and the lower cover, and the third magnet is used for mounting the lens module and the main body of the electronic device.

[0053] Thus, the lens module can be conveniently mounted on the main body of the electronic device through the magnetic adsorption of the third magnet, thereby simplifying the mounting process of the lens module and the main body of the electronic device.

[0054] In a possible implementation of the first aspect, the lens module includes a supporting seat and a lens assembly arranged on the supporting seat, the lens assembly is arranged on the side of the supporting seat facing the light incident, the insertion portion is arranged on the supporting seat, and the supporting seat slides relative to the base sleeve along the extension direction of the first sliding groove through the insertion portion.

[0055] Thus, the supporting seat can slide relative to the base sleeve along the extension direction of the first slide groove through the insertion part, so that the lens assembly can slide relative to the base sleeve along the extension direction of the first slide groove, so that when the insertion part is damaged by friction due to sliding along the first slide groove and needs to be replaced, only the supporting seat and the insertion part need to be replaced, avoiding the situation where the lens assembly needs to be replaced due to friction damage caused by sliding along the first slide groove, and saving the cost of repairing and replacing parts of the lens module.

[0056] In a second aspect, an embodiment of the present application further discloses an electronic device, comprising:

[0057] main body;

[0058] The lens module according to any one of the first aspects, wherein the lens module is detachably mounted on the main body; and

[0059] A photosensitive chip is arranged on the main body and is located at the image side end of the lens module.

[0060] In this embodiment, the lens module is detachably mounted on the main body, allowing the lens module to be mounted on the electronic device as an interchangeable lens. This allows the electronic device to be combined with lens modules having different focusing ranges, thereby enabling the electronic device to capture images similar to those of a single-lens reflex camera. Furthermore, the photosensitive chip is mounted on the main body, located on the image side of the lens module. This not only allows the photosensitive chip to receive light passing through the lens assembly, but also, compared to mounting the photosensitive chip on the lens module, increases the range of movement of the lens assembly along the optical axis, broadening the focusing range of the lens module, but also effectively prevents damage to the photosensitive chip caused by disassembly of the lens module.

[0061] Compared with the prior art, this application has at least the following beneficial effects:

[0062] In the present application, a rotating sleeve is provided over the lens module and is rotatably connected to the base sleeve about an optical axis. A first light hole coaxial with the optical axis is provided on the top of the rotating sleeve, so that external light can enter the lens module through the first light hole to be converged on the lens module and form an image. A first slide groove is provided on the wall of the rotating sleeve, extending spirally along the wall toward the top of the rotating sleeve. The first slide groove includes a plurality of slide groove segments connected in sequence. An insertion portion is slidably inserted into the first slide groove along the extension direction of the first slide groove. When the rotating sleeve rotates relative to the base sleeve about the optical axis, the insertion portion slides along the extension direction of the first slide groove to drive the lens module to slide relative to the base sleeve along the optical axis, so that the lens module can move along the optical axis, so that the lens module can adjust the focal length by rotating the rotating sleeve, and the image captured by the lens module can be clear.

[0063] In addition, the first slide groove includes a plurality of slide groove sections connected in sequence, and the slopes of at least two of the plurality of slide groove sections are different from each other. The insertion part is slidably inserted into the first slide groove along the extension direction of the first slide groove, so that when the rotating sleeve rotates, the lens module can be driven to move along the optical axis direction through the cooperation between the insertion part and the first slide groove, that is, the rotating sleeve is rotated, and the groove wall of the first slide groove on the rotating sleeve can squeeze the insertion part to slide along the extension direction of the first slide groove. When the insertion part slides in the slide groove sections with different slopes, on the one hand, different friction resistances can be generated between the insertion part and the groove wall of the slide groove section, so that the force for rotating the rotating sleeve is different, so that the user can rotate the rotating sleeve. The rotating sleeve can have different hand feelings when rotating; on the other hand, when the user rotates the rotating sleeve, a step difference feeling is generated when the insertion part slides in the slide groove sections with different slopes, so that the change in the user's hand feeling when rotating the rotating sleeve is more obvious, thereby reminding the user that the lens module is adjusted to a certain focal length. Compared with the first slide groove being composed of slide groove sections with the same slope, the user needs to judge whether to adjust the lens module to the focal length by observing the changes in the captured image, which causes the user to repeatedly rotate the rotating sleeve for multiple times to successfully focus. This method can effectively shorten the user's adjustment time for the focal length of the lens module and improve the user's experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0097] The technical solution of this application will be described in detail below with reference to specific embodiments and drawings.

[0098] Example 1

[0099] The embodiment of the present application provides a lens module, such as Figure 1-Figure 5 As shown, it includes a base sleeve 1, a lens module 2 and a rotating sleeve 3, wherein the lens module 2 is along the optical axis direction of the lens module 2 (as shown in FIG. Figure 1The cam 31 is connected to the base sleeve 1 and the lens module 2 is connected to the lens module 2 by the first sliding groove 32, so that the lens module 2 can be moved along the optical axis by the first sliding groove 32 when the rotating sleeve 3 is rotated.

[0100] It should be explained that the top of the rotating sleeve 3 mentioned above refers to the end of the rotating sleeve 3 facing the object side.

[0101] It should also be explained that the different slopes of at least two of the above-mentioned multiple chute segments mean that when the wall of the rotating sleeve 3 is unfolded into a plane, the slopes of at least two chute segments on the wall of the chute are different.

[0102] In this embodiment, the rotating sleeve 3 is covered on the lens module 2 and is rotatably connected to the base sleeve 1 around the optical axis. A first light hole 31 coaxial with the optical axis is provided on the top of the rotating sleeve 3, so that external light can enter the lens module 2 through the first light hole 31 to converge on the lens module 2 and form an image. A first slide groove 32 is provided on the wall of the rotating sleeve 3, which spirally extends along the wall toward the top of the rotating sleeve 3. The first slide groove 32 includes a plurality of slide groove sections connected in sequence. The insertion portion 23 is slidably inserted into the first slide groove 32 along the extension direction of the first slide groove 32. When the rotating sleeve 3 rotates relative to the base sleeve 1 around the optical axis, the insertion portion 23 is slidable along the extension direction of the first slide groove 32 to drive the lens module 2 to slide relative to the base sleeve 1 along the optical axis direction, so that the lens module 2 can move along the optical axis direction, thereby adjusting the distance between the lens module 2 and the photosensitive chip, so that the lens module 2 can adjust the focal length by rotating the rotating sleeve 3, so that the image captured by the lens module 2 can be clear.

[0103] The first slide groove 32 includes a plurality of slide groove sections connected in sequence, and the slopes of at least two of the plurality of slide groove sections are different from each other. The insertion portion 23 is slidably inserted into the first slide groove 32 along the extension direction of the first slide groove 32, so that when the rotating sleeve 3 rotates, the lens module 2 can be driven to move along the optical axis direction through the cooperation of the insertion portion 23 and the first slide groove 32, that is, the rotating sleeve 3 is rotated, and the groove wall of the first slide groove 32 on the rotating sleeve 3 can squeeze the insertion portion 23 to slide along the extension direction of the first slide groove 32, so that when the insertion portion 23 slides in the slide groove sections with different slopes, on the one hand, different friction resistances can be generated between the insertion portion 23 and the groove wall of the slide groove section, so that the force for rotating the rotating sleeve 3 is different. The user can have different hand feelings when rotating the rotating sleeve 3; on the other hand, when the user rotates the rotating sleeve 3, a step difference feeling is generated when the insertion portion 23 slides in the slide groove sections with different slopes, so that the change in the user's hand feeling when rotating the rotating sleeve 3 is more obvious, thereby reminding the user that the lens module 2 is adjusted to a certain focal length. Compared with the first slide groove 32 being composed of slide groove sections with the same slope, the user needs to judge whether to adjust the lens module 2 to the focal length by observing the changes in the captured image, which causes the user to repeatedly rotate the rotating sleeve 3 multiple times before successfully adjusting the focus. This can effectively shorten the user's adjustment time for the focal length of the lens module 110 and improve the user experience.

[0104] It should be explained that the above-mentioned step difference feeling means that at least two slide groove sections with different slopes can form a roughly stepped first slide groove 32, so that when the insertion part 23 slides in the first slide groove 32, the insertion part 23 is like sliding on a step, and the feeling of blockage, change in sliding distance, etc. is generated.

[0105] The slopes of at least two of the above-mentioned multiple chute sections are different from each other, and the slope of one of the multiple chute sections may be larger. For example, the slope of one of the chute sections may be a slope along the wall of the rotating sleeve 3 toward the top of the rotating sleeve 3, and the angle between the groove wall of the chute section and the optical axis is 30°; the slope of another of the multiple chute sections may be smaller. For example, the slope of another chute section may be a slope along the wall of the rotating sleeve 3 toward the top of the rotating sleeve 3, and the angle between the groove wall of the chute section and the optical axis is 90°, that is, the chute section extends along the circumferential direction of the rotating sleeve 3, or the slope of another chute section is a slope along the wall of the rotating sleeve 3 toward the top of the rotating sleeve 3, and the angle between the groove wall of the chute section and the optical axis is 60°. As long as the slopes of at least two chute sections can be different from each other and the user can have a more obvious hand feel, it is not limited here.

[0106] In addition, the slopes of at least two of the multiple chute segments are different from each other. The number of chute segments with different slopes can be two, three, or four, which is not limited here.

[0107] Alternatively, as Figure 4 and Figure 6 As shown, the multiple chute sections include a first chute section 321 and a second chute section 322. The first chute section 321 extends along the circumference of the rotating sleeve 3, and the second chute section 322 is arranged on the rotating sleeve 3 at an angle to the first chute section 321, and the angle at the connection between the first chute section 321 and the second chute section 322 is an obtuse angle.

[0108] Therefore, when the insertion part 23 slides from the first slide groove section 321 into the second slide groove section 322, or slides from the second slide groove section 322 into the first slide groove section 321, the change in friction resistance between the insertion part 23 and the first slide groove 32 can be relatively obvious, and the step difference between the first slide groove section 321 and the second slide groove section 322 is also relatively obvious, so that the user can clearly feel the change in hand feel, and the reminder to the user that the lens module 2 has been adjusted to a certain focal length position is more obvious.

[0109] The first chute section 321 extends along the circumference of the rotating sleeve 3, and the second chute section 322 is arranged on the rotating sleeve 3 at an angle to the first chute section 321. The angle between the first chute section 321 and the second chute section 322 is an obtuse angle. When the first chute section 321 and the second chute section 322 are sequentially connected along the direction of the optical axis, they can jointly form a stepped first chute 32. The location where the first chute section 321 and the second chute section 322 connect with each other can be smoothly transitioned, so that when the insert portion 23 slides from one of the two into the other, the insert portion 23 can slide smoothly, making the rotation of the rotating sleeve 3 smooth and effortless.

[0110] In addition, the first slide groove section 321 extends along the axial direction of the rotating sleeve 3, that is, the extension direction of the first slide groove section 321 is perpendicular to the optical axis, so that when the insertion part 23 slides to the first slide groove section 321, the insertion part 23 can be maintained in the first slide groove section 321 without external force, so that the lens module 2 can maintain the focal length corresponding to the first slide groove section 321 when focusing on the focal length, which facilitates the user to shoot at this focal length.

[0111] Optionally, there are multiple first chute sections 321 and multiple second chute sections 322 , and the multiple first chute sections 321 and the multiple second chute sections 322 are arranged at intervals.

[0112] In this way, the insertion portion 23 can slide in multiple first slide groove sections 321 and multiple second slide groove sections 322, so that the lens module 2 can be adjusted between multiple focal lengths, that is, the lens module 110 can have multiple focusing focal lengths, so that the lens module 110 can take clearer pictures of scenes at different distances, and can remind the user that the lens module 110 is adjusted to different focal lengths through changes in hand feel.

[0113] Among them, multiple first sliding groove sections 321 and multiple second sliding groove sections 322 are arranged at intervals, and along the direction of the cylinder wall of the rotating sleeve 3 toward the cylinder top of the rotating sleeve 3, multiple first sliding groove sections 321 and multiple second sliding groove sections 322 can be arranged at intervals in sequence, that is, in the process of the insertion portion 23 sliding along the first sliding groove 32 from the end of the rotating sleeve 3 away from the cylinder top to the end close to the cylinder top, the insertion portion 23 will first slide in the first sliding groove section 321, then slide in the second sliding groove section 322, and then slide in the other adjacent first sliding groove section 321, and slide alternately in the first sliding groove section 321 and the second sliding groove section 322 in sequence. In this way, the insertion end can slide alternately in the first sliding groove section 321 and the second sliding groove section 322 in sequence, so that different hand feels can be generated in the process of rotating the rotating sleeve 3, so as to remind the user that the lens module 110 is adjusted to different focal lengths.

[0114] For example, the first slot section 321, which is the farthest from the top of the rotating sleeve 3, can be set as the initial focal length position of the lens module 2. Along the direction toward the top of the rotating sleeve 3, the first slot section 321, which is the second farthest from the top of the rotating sleeve 3, corresponds to a focal length of 15 cm for the camera module. The first slot section 321, which is the third farthest from the top of the rotating sleeve 3, corresponds to a focal length of 10 cm. Similarly, different first slot sections 321 can correspond to different focal lengths. The second slot section 322, which is connected between two adjacent first slot sections 321, can be set as the path along which the insert portion 23 slides when adjusting the focal length. In this way, when the insert portion 23 slides from the second slot section 322 into the first slot section 321, the frictional resistance encountered by the insert portion 23 is reduced, making the user feel that rotating the rotating sleeve 3 becomes light and effortless, thereby reminding the user that the focal length adjustment of the lens module 2 is basically in place and that it is necessary to slow down the rotation of the rotating sleeve 3 or stop rotating the rotating sleeve 3.

[0115] Of course, multiple first slide groove sections 321 and multiple second slide groove sections 322 are arranged at intervals, and it is also possible that when the insertion part 23 slides along the first slide groove 32 from the end of the rotating sleeve 3 away from the first light hole 31 to the end close to the top of the rotating sleeve 3, the insertion part 23 will first slide in the second slide groove section 322, then slide in the first slide groove section 321, and then slide in another adjacent second slide groove section 322, and slide alternately in the second slide groove section 322 and the first slide groove section 321 in turn.

[0116] In some embodiments, as Figure 4-Figure 7 As shown, a guide member 11 is provided on the side of the base sleeve 1 facing the lens module 2, and a second slide groove 111 extending along the optical axis direction is provided on the guide member 11. The insertion portion 23 is sequentially inserted into the second slide groove 111 and the first slide groove 32, and the insertion portion 23 is slidably connected to the second slide groove 111 along the extension direction of the second slide groove 111.

[0117] Therefore, the insertion portion 23 is sequentially inserted into the second slide groove 111 and the first slide groove 32, so that when the rotating sleeve 3 is rotated to drive the insertion portion 23 to slide along the first slide groove 32, the insertion portion 23 also slides along the extension direction of the second slide groove 111 at the same time, that is, the rotation of the rotating sleeve 3 can drive the insertion portion 23 to slide along the optical axis, so that the insertion portion 23 can drive the lens module 2 to move along the optical axis, so that the lens module 2 can always be located in the light path reflected by the scene, so that the lens module 2 can focus under the drive of the insertion portion 23.

[0118] Among them, the insertion part 23 can have a variety of structural forms. For example, the insertion part 23 can be a sliding block or a sliding shaft 231, so that the contact area between the insertion part 23 and the groove wall of the first slide groove 32 and the groove wall of the second slide groove 111 is smaller, so that the friction resistance encountered by the sliding of the insertion part 23 can be smaller. Of course, the structure of the insertion part 23 can also be other forms, which is not limited here.

[0119] In addition, the number of insertion parts 23 can be one, so that the rotation of the rotating sleeve 3 only needs to overcome the friction resistance of one insertion part 23, which is light and labor-saving; it can also be multiple, such as two, three, four, etc., so that the lens module 2 can be moved through multiple insertion parts 23 at the same time, smoothly and firmly.

[0120] Optionally, when the insertion portion 23 is a sliding shaft 231, and the number of the sliding shafts 231 is multiple, the multiple sliding shafts 231 are evenly distributed on the lens module 2 around the optical axis, the number of the first sliding grooves 32 and the second sliding grooves 111 are both multiple, and the multiple first sliding grooves 32 and the multiple second sliding grooves 111 correspond one-to-one to the multiple sliding shafts 231.

[0121] Thus, all parts of the lens module 2 around the optical axis can be moved simultaneously through the sliding shaft 231, and the movement is more stable, firm, light and labor-saving.

[0122] Among them, multiple sliding shafts 231 are evenly distributed around the optical axis on the lens module 2, and multiple first sliding grooves 32 and multiple second sliding grooves 111 correspond one-to-one to the multiple sliding shafts 231, and the corresponding multiple first sliding grooves 32 are evenly distributed around the optical axis on the copper wall of the rotating sleeve 3, and the multiple second sliding grooves 111 are evenly distributed around the optical axis on the side of the base sleeve 1 facing the lens module 2.

[0123] The number of the sliding shafts 231 can be any number such as two, three, four, etc., and is not limited here.

[0124] The above-mentioned guide member 11 can have multiple implementation methods. In one possible implementation method, the guide member 11 can be a guide rod arranged on the side of the base sleeve 1 facing the lens module 2. The guide rod extends along the optical axis, and the second slide groove 111 is arranged on the guide rod. The structure is simple and can reduce the weight of the lens module 110.

[0125] In another possible implementation, Figure 7 As shown, the guide member 11 is a tubular structure extending toward the lens module 2 , the tubular structure having a tubular cavity 112 , the lens module 2 can be slidably accommodated in the tubular cavity 112 , and the second slide groove 111 is opened on the wall of the tubular structure and communicates with the tubular cavity 112 .

[0126] Thus, the lens module 2 can move along the optical axis in the tube cavity 112 of the tubular structure, so that while the lens module 2 can realize movement along the optical axis by sliding the insertion part 23 in the first slide groove 32 and the second slide groove 111, it can also be restricted by the tube wall of the tubular structure from moving in a direction perpendicular to the optical axis, so that the lens module 2 can only move along the optical axis, so that the focus of the focal length of the lens module 2 can always be on the light path reflected by the scene, thereby making it possible to make the adjustment of the focal length of the lens module 2 simple and quick.

[0127] The cross-sectional shape of the tubular structure's lumen 112 along the optical axis can have various shapes, such as a rectangle, a circle, or an ellipse, and this is not limited here. Accordingly, the shape of the projection of the lens module 2 along the optical axis can match the cross-sectional shape of the tubular structure's lumen 112 along the optical axis, i.e., a rectangle, a circle, or an ellipse, and this is not limited here.

[0128] The above-mentioned insertion portion 23 is arranged on the lens module 2 and can be arranged at multiple positions of the lens module 2. The insertion portion 23 can be arranged on the outer peripheral wall of the lens module 2 surrounding the optical axis. For example, the lens module 2 can include a lens assembly 22 and a shell surrounding the outer periphery of the lens module 2, and the insertion portion 23 can be arranged on the shell; or the insertion portion 23 can be arranged on the side of the lens module 2 facing the base sleeve 1; of course, the insertion portion 23 can also be arranged at other positions on the lens module 2, which is not limited here.

[0129] Alternatively, as Figure 7 As shown, the lens module 2 may include a supporting seat 21 and a lens assembly 22 arranged on the supporting seat 21, the lens assembly 22 is arranged on the side of the supporting seat 21 facing the light incident, and the insertion portion 23 is arranged on the supporting seat 21, and the supporting seat 21 slides relative to the base sleeve 1 along the extension direction of the first sliding groove 32 through the insertion portion 23.

[0130] Thus, the supporting seat 21 can slide relative to the base sleeve 1 along the extension direction of the first sliding groove 32 through the insertion part 23, so that the lens assembly 22 can slide relative to the base sleeve 1 along the extension direction of the first sliding groove 32, so that when the insertion part 23 is damaged by friction due to sliding along the first sliding groove 32 and needs to be replaced, only the supporting seat 21 and the insertion part 23 need to be replaced, avoiding the situation where the lens assembly 22 needs to be replaced due to friction damage caused by the insertion part 23, thereby saving the cost of repairing and replacing parts of the lens module 110.

[0131] Among them, when the guide member 11 is a tubular structure, and the cross-sectional shape of the lumen 112 of the tubular structure along the optical axis direction is a rectangle, the cross-sectional shape of the lens assembly 22 along the optical axis direction may be a rectangle matching the lumen 112, so that the cavity wall of the lumen 112 can limit the movement of the lens assembly 22 in the direction perpendicular to the optical axis; the cross-sectional shape of the support seat 21 along the optical axis direction may be circular, and the outer peripheral wall of the support seat 21 may be movably abutted against the cavity wall of the lumen 112, or it may be a combination of circular and rectangular, that is, the outer peripheral wall of the support seat 21 may be formed by multiple arc surfaces and multiple planes spaced apart and connected, and the plane part may be movably abutted against the cavity wall of the lumen 112, so that the cavity wall of the lumen 112 can limit the movement of the support seat 21 in the direction perpendicular to the optical axis, thereby further limiting the movement of the lens assembly 22 in the direction perpendicular to the optical axis.

[0132] In addition, the lens assembly 22 is disposed on the supporting base 21 . The lens assembly 22 may be bonded to the supporting base 21 , or may be connected to the supporting base 21 via screw threads, which is not limited here.

[0133] The insertion portion 23 is arranged on the bearing seat 21. The insertion portion 23 and the bearing seat 21 can be integrally formed, or the insertion portion 23 can be fixed to the bearing seat 21 by bonding, or an insertion hole can be provided on the bearing seat 21, and the insertion portion 23 and the insertion hole are fixed in the insertion hole by interference fit. This is not limited here.

[0134] In some embodiments, as Figure 4 and Figure 8 As shown, the lens module 110 also includes an outer sleeve 4, which is sleeved on the outside of the rotating sleeve 3. A second light hole 41 coaxial with the optical axis is provided on the top of the outer sleeve 4. The outer sleeve 4 is fixedly connected to the base sleeve 1 and is rotatably connected to the rotating sleeve 3 around the optical axis. The rotating sleeve 3 is located between the outer sleeve 4 and the base sleeve 1.

[0135] Thus, the outer sleeve 4 can protect the rotating sleeve 3 to prevent foreign matter such as dust and fibers from entering the rotating sleeve 3 and affecting the rotation of the rotating sleeve 3 .

[0136] In addition, a second light hole 41 coaxial with the optical axis is provided on the top of the outer sleeve 4, so that the light reflected by the external scene can reach the lens module 2 through the second light hole 41 and the first light hole 31, thereby ensuring that the lens module 110 can capture the image of the scene.

[0137] Among them, the outer sleeve 4 is fixedly connected to the base sleeve 1. The outer sleeve 4 can be bonded to the base sleeve 1, or the outer sleeve 4 can be clamped to the base sleeve 1, or the outer sleeve 4 can be threadedly fixedly connected to the base sleeve 1 through a threaded pair, which is not limited here.

[0138] Alternatively, as Figures 9-11 As shown, the lens module 110 also includes a gear assembly 5, through which the outer sleeve 4 is rotatably connected to the rotating sleeve 3 around the optical axis. The gear assembly 5 is used to make the friction between the outer sleeve 4 and the rotating sleeve 3 different when the insertion portion 23 slides along two slide groove sections with different slopes.

[0139] Thus, the outer sleeve 4 is rotatably connected to the rotating sleeve 3 around the optical axis through the gear assembly 5, so that when the insertion part 23 slides along the two slide groove sections with different slopes, the friction between the outer sleeve 4 and the rotating sleeve 3 is different. When the insertion part 23 slides along the two slide groove sections with different slopes, the force required to rotate the rotating sleeve 3 is different, so that the user will have a different feel when rotating the rotating sleeve 3, thereby enabling the user to adjust the focal length of the lens module 110 more quickly, thereby providing the user with a better user experience.

[0140] Among them, Figure 10 and Figure 11As shown, the gear assembly 5 includes a first gear member 51, a second gear member 52 and an abutment drive assembly 53, wherein the first gear member 51 is arranged on the rotating sleeve 3, the second gear member 52 is arranged on the outer sleeve 4, and the abutment drive assembly 53 is arranged on the rotating sleeve 3 and / or the outer sleeve 4, and the abutment drive assembly 53 is used to provide the rotating sleeve 3 with a force to bear against the outer sleeve 4 so that a friction force is generated when the rotating sleeve 3 rotates relative to the outer sleeve 4; when the insertion portion 23 slides in one of the multiple slide groove sections, the first gear member 51 and the second gear member 52 are opposite to each other along the optical axis, and there is a first friction force between the outer sleeve 4 and the rotating sleeve 3; when the insertion portion 23 slides in another slide groove section with a different slope among the multiple slide groove sections, the first gear member 51 and the second gear member 52 are staggered along the optical axis direction, and there is a second friction force between the outer sleeve 4 and the rotating sleeve 3, and the first friction force and the second friction force are different from each other.

[0141] Therefore, when the insertion portion 23 slides in different slide groove sections, the relative positions of the first gear member 51 and the second gear member 52 along the optical axis direction change, so that the sliding contact area between the outer sleeve 4 and the rotating sleeve 3 changes, thereby generating different first friction forces and second friction forces between the outer sleeve 4 and the rotating sleeve 3, so that the feel of rotating the rotating sleeve 3 can be changed, and this change does not require additional operation. The different feel can be produced by rotating the rotating sleeve 3, and the operation is simple and convenient.

[0142] The abutment drive assembly 53 is used to provide the rotating sleeve 3 with a force to bear against the outer sleeve 4, so that the rotating sleeve 3 can abut against the outer sleeve 4, so that friction can be generated between the two when the rotating sleeve 3 rotates relative to the outer sleeve 4. At the same time, the outer sleeve 4 can also provide bearing for the rotating sleeve 3 when the rotating sleeve 3 rotates, thereby avoiding the rotating sleeve 3 from tilting in the direction perpendicular to the optical axis due to the change in the relative position between the first gear member 51 and the second gear member 52, thereby avoiding the first light hole 31 from moving in the direction perpendicular to the optical axis relative to the lens module 2 due to the tilt of the rotating sleeve 3 in the direction perpendicular to the optical axis, thereby affecting the shooting quality.

[0143] Among them, the abutment drive component 53 is arranged on the rotating sleeve 3 and / or the outer sleeve 4. The abutment drive component 53 can be arranged on the rotating sleeve 3; or the abutment drive component 53 can be arranged on the outer sleeve 4; or a part of the abutment drive component 53 can be arranged on the rotating sleeve 3, and the other part can be arranged on the outer sleeve 4, which is not limited here.

[0144] There are many ways to implement the first shift member 51 and the second shift member 52. In one possible implementation, Figure 10 and Figure 11As shown, the first gear member 51 is a protrusion 511, which protrudes from the rotating sleeve 3 and faces the outer sleeve 4; the second gear member 52 is a groove 521 that is recessed in the direction away from the rotating sleeve 3. When the insertion portion 23 slides in one of the multiple slide groove sections, the protrusion 511 is located in the groove 521, and the rotating sleeve 3 is rotationally connected to the outer sleeve 4 to form a first friction force. When the insertion portion 23 slides in another slide groove section with a different slope among the multiple slide groove sections, the protrusion 511 is located outside the groove 521, and the rotating sleeve 3 is rotationally connected to the outer sleeve 4 through the protrusion 511 to form a second friction force.

[0145] Therefore, when the rotating sleeve 3 is rotated, the protrusion 511 can slide into the groove 521 and slide in the groove 521, so that the rotating sleeve 3 and the outer sleeve 4 are in direct contact and rotationally connected to form a first friction force, and the protrusion 511 can also slide outside the groove 521, and the protrusion 511 contacts and rotates with the outer sleeve 4 to form a second friction force between the rotating sleeve 3 and the outer sleeve 4, so that the contact area of the rotational connection between the rotating sleeve 3 and the outer sleeve 4 can have a more obvious change, so that the first friction force and the second friction force can have a significant difference, so that the feel of rotating the rotating sleeve 3 has a significant change, and the structure of the first gear member 51 and the second gear member 52 is simple and easy to implement.

[0146] Of course, the first shifting member 51 may also be a groove 521 on the rotating sleeve 3 that is recessed away from the outer sleeve 4 , and the second shifting member 52 may also be a protruding member 511 that protrudes from the outer sleeve 4 and faces the rotating sleeve 3 , which is not limited here.

[0147] The protruding member 511 protrudes from the rotating sleeve 3 and faces the rotating outer sleeve 4. The protruding member 511 can be provided on a surface of the rotating sleeve 3 facing the outer sleeve 4. The protruding member 511 can be integrally formed with the rotating sleeve 3, can be adhered to the rotating sleeve 3 by adhesive, or can be rotatably embedded in the rotating sleeve 3, without limitation herein.

[0148] In addition, when the multiple sliding groove sections include a first sliding groove section 321 and a second sliding groove section 322, when the insertion portion 23 slides in the first sliding groove section 321, the protrusion 511 can be located in the groove 521, and the rotating sleeve 3 and the outer sleeve 4 are in direct contact and rotationally connected to form a first friction force, that is, the contact area between the rotating sleeve 3 and the outer sleeve 4 can be relatively large, and the first friction force formed is relatively large; when the insertion portion 23 slides in the second sliding groove section 322, the protrusion 511 can be located outside the groove 521, and the protrusion 511 and the outer sleeve 4 are rotationally connected to form a second friction force, that is, at this time, the friction force between the rotating sleeve 3 and the outer sleeve 4 is generated by the mutual contact friction between the protrusion 511 and the outer sleeve 4, and the second friction force formed can be smaller. In this way, there can be a significant difference between the first friction force and the second friction force, so that the feel of rotating the rotating sleeve 3 can have a significant change, to remind the user that the lens module 2 has moved to the focusing position.

[0149] In another possible implementation of the first gear member 51 and the second gear member 52, the first gear member 51 may be an arc-shaped groove, which extends around the optical axis and has openings at both ends in its own extension direction, that is, the arc-shaped groove may be enclosed by two concentric arc surfaces, and the second gear member 52 is a protrusion 511 protruding toward the arc-shaped groove, and the distance between the two arc surfaces of the arc-shaped groove is slightly smaller than the dimension of the protrusion 511 along the relative directions of the two arc surfaces; when the insertion part 23 slides in one of the multiple slide groove sections, the protrusion 511 may be located in the arc-shaped groove and may slide in the arc-shaped groove, and a first friction force is formed between the rotating sleeve 3 and the outer sleeve 4 through the rotational connection between the protrusion 511 and the arc-shaped groove; when the insertion part 23 slides in another slide groove section with a different slope among the multiple slide groove sections, the protrusion 511 is located outside the arc-shaped groove, and the rotating sleeve 3 and the outer sleeve 4 are rotationally connected through the protrusion 511 to form a second friction force. Therefore, when the protrusion 511 is located in the arc groove and slides in the arc groove, the protrusion 511 can generate a large friction resistance with the two arc surfaces of the arc groove to form a first friction force; when the protrusion 511 is located outside the arc groove, the protrusion 511 will slide in contact with the outer sleeve 4 or the rotating sleeve 3, and the contact area is small. A small friction resistance is generated between the protrusion 511 and the outer sleeve 4 or the rotating sleeve 3 to form a second friction force, so that the feel of rotating the rotating sleeve 3 can have a significant change, so as to remind the user that the lens module 2 has moved to the focusing position.

[0150] Exemplarily, when the multiple slide groove sections include a first slide groove section 321 and a second slide groove section 322, when the insertion portion 23 slides in the first slide groove section 321, the protrusion 511 can be located in the arc groove, and the rotating sleeve 3 and the outer sleeve 4 are rotatably connected to the arc groove through the protrusion 511 to form a first friction force; when the insertion portion 23 slides in the second slide groove section 322, the protrusion 511 can be located outside the arc groove, and the rotating sleeve 3 and the outer sleeve 4 are rotatably connected to the outer sleeve 4 through the protrusion 511 to form a second friction force.

[0151] Alternatively, the protruding member 511 may be a projection or a ball, both of which are simple and easy to implement, and are not limited to this. Furthermore, when the protruding member 511 is a ball, the contact between the ball and the outer sleeve 4 can be point contact, which can effectively reduce the frictional resistance between the protruding member 511 and the outer sleeve 4.

[0152] In addition, when the first stop member 51 is a protruding member 511 and the second stop member 52 is a groove 521 on the outer sleeve 4 that is recessed in a direction away from the rotating sleeve 3, as shown in FIG. Figure 11 and Figure 12 As shown, there are multiple grooves 521, and the multiple grooves 521 are arranged on the outer sleeve 4 at intervals along the circumference of the outer sleeve 4, and the multiple grooves 521 are located on the same circle perpendicular to the optical axis. The protruding member 511 can slide between the multiple grooves 521, that is, the multiple grooves 521 can form a groove combination 52a (such as Figure 12 As shown in the multiple grooves in the dotted box, one groove combination 52a may correspond to one protruding member 511, and the protruding member 511 may slide between the multiple grooves 521 in the corresponding groove combination 52a.

[0153] Thus, multiple grooves 521 are arranged on the outer sleeve 4 at intervals along the circumference of the outer sleeve 4, and the multiple grooves 521 are located on the same circle perpendicular to the optical axis, forming a groove combination 52a. A protrusion 511 slides between the multiple grooves 521 in a groove combination 52a, so that each groove 521 corresponds to a focal length position, so that the lens module 110 can have multiple focal length positions that are easy to adjust into place, thereby enabling the lens module 110 to quickly and clearly capture scenes at different distances.

[0154] The number of the grooves 521 can be any number such as two, three, four, etc., and is not limited here.

[0155] Exemplarily, when the number of grooves 521 is four, the four grooves 521 are located on the same circle perpendicular to the optical axis to form a groove combination 52a. The focal length positions corresponding to the four grooves 521 are defined as the initial focal length position, 15cm focal length position, 10cm focal length position and 5cm focal length position in a clockwise or counterclockwise direction, so that when the rotating sleeve 3 is rotated to make the protrusion 511 slide between the four grooves 521, the user can be reminded that the lens module 2 is moved to the initial focal length position, 15cm focal length position, 10cm focal length position or 5cm focal length position, so that the user can quickly find the initial focal length, 15cm focal length, 10cm focal length or 5cm focal length of the lens module 110, thereby improving the user's experience.

[0156] In addition, the distance between two adjacent grooves 521 among the multiple grooves 521 corresponds to the displacement of the insertion portion 23 when sliding from one of the multiple slide groove sections to another adjacent slide groove section with the same slope (such as the displacement from the first slide groove section 321 to the adjacent another first slide groove section 321), and also corresponds to the distance that the lens module 2 moves from one focal length position to another adjacent focal length position.

[0157] Alternatively, as Figure 11 and Figure 12 As shown, a guiding portion 5211 is provided on the groove wall of the adjacent grooves 521, and a blocking portion 5212 is provided on the groove wall of the first groove 521. The first groove 521 is the groove 521 located at both ends among the multiple grooves 521, and the blocking portion 5212 is opposite to the guiding portion 5211 provided on the groove wall of the first groove 521.

[0158] Thus, by providing guide portions 5211 on the groove walls of adjacent grooves 521, the protruding member 511 can smoothly slide out of one groove 521 and slide into another groove 521. At the same time, the rotating sleeve 3 can be smoothly abutted against the outer sleeve 4 under the action of the abutment drive assembly 53, thereby reducing the probability of the rotating sleeve 3 tilting during rotation. Blocking portions 5212 are provided on the groove walls of the first grooves 521 located at the two ends of the multiple grooves 521 to prevent the protruding member 511 from sliding out of the groove combination 52a when sliding into the grooves 521 located at the two ends of the multiple grooves 521, thereby avoiding the slow focusing speed of the lens module 110 caused by the protruding member 511 sliding out of the groove combination 52a.

[0159] Among them, the guide portion 5211 can be a slope arranged on the groove wall, one end of the slope is connected to the bottom surface of the groove 521, and the other end of the slope is connected to the surface of the outer sleeve 4; or the guide portion 5211 can be an arc-shaped slope arranged on the groove wall, one end of the slope is connected to the bottom surface of the groove 521, and the other end of the slope is connected to the surface of the outer sleeve 4. Of course, the guide portion 5211 can also be other structural forms, which are not limited here.

[0160] The above-mentioned blocking portion 5212 can be a protrusion set on the groove wall to prevent the protruding piece 511 from sliding out of the groove 521 through the groove wall, or it can be a plane set on the groove wall and perpendicular to the bottom surface of the groove 521. The above structures are simple and easy to implement, and are not limited here.

[0161] Alternatively, as Figure 12 As shown, the number of groove combinations 52a is at least two, and the at least two groove combinations 52a are evenly arranged along the circumference of the outer sleeve 4, and the at least two groove combinations 52a are located on the same circle perpendicular to the optical axis; the number of protrusions 511 is at least two, and the at least two protrusions 511 correspond one-to-one to the at least two groove combinations 52a.

[0162] Therefore, at least two groove combinations 52a are evenly arranged along the circumference of the outer sleeve 4, and at least two groove combinations 52a are located on the same circle perpendicular to the optical axis. At least two protrusions 511 correspond one-to-one to at least two groove combinations 52a, which can prevent the rotating sleeve 3 from tilting when it leans against the outer sleeve 4 under the action of the abutment drive assembly 53 when the protrusion 511 is located outside the groove 521, thereby avoiding the influence of the tilt of the rotating sleeve 3 on the shooting of the lens module 2.

[0163] The number of the groove combinations 52a can be any number among two, three, four, etc., and is not limited thereto. The number of the protrusions 511 can also be any number among two, three, four, etc., and is not limited thereto.

[0164] In some embodiments, as Figure 10-13 As shown, the surface of the rotating sleeve 3 provided with the first gear 51 is also provided with a first protrusion 33 protruding toward the outer sleeve 4, and the surface of the outer sleeve 4 provided with the second gear 52 is also provided with a second protrusion 42 protruding toward the rotating sleeve 3. When the first gear 51 and the second gear 52 are opposite to each other along the optical axis, the rotating sleeve 3 and the outer sleeve 4 are rotationally connected through the first protrusion 33 and the second protrusion 42 to form a first friction force. When the first gear 51 and the second gear 52 are staggered along the optical axis, there is a gap between the first protrusion 33 and the outer sleeve 4, and between the second protrusion 42 and the rotating sleeve 3. The rotating sleeve 3 is rotationally connected to the outer sleeve 4 through the first gear 51 or the second gear 52 to form a second friction force.

[0165] Alternatively, a first protrusion 33 protruding toward the outer sleeve 4 is also provided on the surface of the rotating sleeve 3 on which the first gear member 51 is provided. When the first gear member 51 and the second gear member 52 are opposite to each other along the optical axis, the rotating sleeve 3 and the outer sleeve 4 are rotatably connected through the first protrusion 33 to form a first friction force. When the first gear member 51 and the second gear member 52 are staggered along the optical axis, there is a gap between the first protrusion 33 and the outer sleeve 4, and the rotating sleeve 3 is rotatably connected to the outer sleeve 4 through the first gear member 51 or the second gear member 52 to form a second friction force.

[0166] Alternatively, a second protrusion 42 protruding toward the rotating sleeve 3 is provided on the surface of the outer sleeve 4 on which the second gear member 52 is provided. When the first gear member 51 and the second gear member 52 are opposite to each other along the optical axis, the rotating sleeve 3 and the outer sleeve 4 are rotatably connected through the second protrusion 42 to form a first friction force. When the first gear member 51 and the second gear member 52 are staggered along the optical axis, there is a gap between the second protrusion 42 and the rotating sleeve 3, and the rotating sleeve 3 is rotatably connected to the outer sleeve 4 through the first gear member 51 or the second gear member 52 to form a second friction force.

[0167] Thus, when the first stopper 51 and the second stopper 52 are relative to each other along the optical axis direction, the first friction force formed between the rotating sleeve 3 and the outer sleeve 4 can be generated between the first protrusion 33 and the outer sleeve 4, and between the second protrusion 42 and the rotating sleeve 3, or between the first protrusion 33 and the outer sleeve 4, or between the second protrusion 42 and the rotating sleeve 3. Compared with the first friction force generated between the side of the rotating sleeve 3 facing the outer sleeve 4 and the side of the outer sleeve 4 facing the rotating sleeve 3, the first friction force can be effectively reduced. When the shifting member 51 and the second shifting member 52 are staggered along the optical axis direction, the rotating sleeve 3 is rotatably connected to the outer sleeve 4 through the first shifting member 51 or the second shifting member 52 to form a second friction force. Similarly, compared with the second friction force generated between the side of the rotating sleeve 3 facing the outer sleeve 4 and the side of the outer sleeve 4 facing the rotating sleeve 3, the second friction force can be effectively reduced. In this way, the first friction force and the second friction force to be overcome by rotating the rotating sleeve 3 can be smaller, so that the rotation of the rotating sleeve 3 can be light and smooth, thereby improving the user experience.

[0168] For example, when the first gear member 51 is a protrusion 511 and the second gear member 52 is a groove 521, a second protrusion 42 protruding toward the rotating sleeve 3 can be provided on the surface of the outer sleeve 4 where the groove 521 is provided. When the protrusion 511 and the groove 521 are opposite to each other along the optical axis, that is, when the protrusion 511 is located in the groove 521, the rotating sleeve 3 and the outer sleeve 4 are rotatably connected to the rotating sleeve 3 through the second protrusion 42 to form a first friction force. When the protrusion 511 and the groove 521 are staggered along the optical axis, that is, when the protrusion 511 is located outside the groove 521, there is a gap between the second protrusion 42 and the rotating sleeve 3, and the rotating sleeve 3 is rotatably connected to the outer sleeve 4 through the protrusion 511 to form a second friction force. The structure is simple and easy to implement, and can effectively avoid the rotating sleeve 3 from tilting significantly when the protrusion 511 slides into or out of the groove 521.

[0169] The number of the aforementioned first protrusions 33 is at least two, and the at least two first protrusions 33 are evenly spaced about the optical axis; and the number of the second protrusions 42 is at least two, and the at least two second protrusions 42 are evenly spaced about the optical axis. Alternatively, only the number of the first protrusions 33 is at least two, and the at least two first protrusions 33 are evenly spaced about the optical axis. In this case, the number of the second protrusion 42 is one, or the outer sleeve 4 is not provided with the second protrusion 42 protruding toward the rotating sleeve 3. Alternatively, only the number of the second protrusions 42 is at least two, and the at least two second protrusions 42 are evenly spaced about the optical axis. In this case, the number of the first protrusion 41 is one, or the rotating sleeve 3 is not provided with the first protrusion 41 protruding toward the outer sleeve 4.

[0170] In this way, when the rotating sleeve 3 leans against the outer sleeve 4, there are at least two contact positions between the rotating sleeve 3 and the outer sleeve 4, and at least the two contact positions are located on the same circle and in the same radial direction, which can effectively prevent the rotating sleeve 3 from tilting under the action of the abutment drive assembly 53. Compared with the first protrusion 33 being a complete circular ring structure around the optical axis, or the second protrusion 42 being a complete circular ring structure around the optical axis, the weight of the rotating sleeve 3 or the outer sleeve 4 can be reduced, saving material.

[0171] The first protrusion 33 and the second protrusion 42 may have various structures. For example, the first protrusion 33 or the second protrusion 42 may be a rectangular protrusion, an arc-shaped protrusion, or a prismatic protrusion, which is not limited here.

[0172] In addition, the number of the first protrusions 33 can be two, three, or four, and is not limited here. The number of the second protrusions 42 can be two, three, or four, and is not limited here.

[0173] The above-mentioned abutment drive assembly 53 for providing the rotating sleeve 3 with a force to bear against the outer sleeve 4 also has multiple implementations. In a first possible implementation, as shown in FIG. Figure 9 and Figure 10 As shown, the abutment drive assembly 53 includes a first magnetic member 531 and a second magnetic member 532 arranged opposite to each other. The first magnetic member 531 is arranged on the side of the rotating sleeve 3 where the first gear member 51 is provided, and the second magnetic member 532 is arranged on the side of the outer sleeve 4 where the second gear member 52 is provided. The first magnetic member 531 and the second magnetic member 532 provide magnetic force for the rotating sleeve 3 to lean toward the outer sleeve 4.

[0174] In this way, the rotating sleeve 3 can always have a tendency to lean towards the outer sleeve 4, so that during the rotation of the rotating sleeve 3, there is always friction between the rotating sleeve 3 and the outer sleeve 4, which facilitates the change of the magnitude of the friction between the rotating sleeve 3 and the outer sleeve 4.

[0175] Among them, the first magnetic part 531 may include multiple first magnets, the multiple first magnets are evenly spaced around the optical axis, and the multiple first magnets are located on the same circle perpendicular to the optical axis; the second magnetic part 532 may include a magnetic ring, the central axis of the magnetic ring is parallel to the optical axis, and the magnetic ring is arranged opposite to the multiple first magnets.

[0176] In this way, the magnetic force between the multiple first magnets and the magnetic ring can be evenly distributed around the optical axis, so that the displacement of each part of the rotating sleeve 3 when it leans against the outer sleeve 4 can be the same, preventing the rotating sleeve 3 from tilting when the rotating sleeve 3 rotates.

[0177] Of course, the first magnetic component 531 may also include a magnetic ring, and the second magnetic component 532 may also include multiple magnets. The multiple magnets are evenly spaced around the optical axis and located on the same circle perpendicular to the optical axis, and are arranged opposite to the magnetic ring.

[0178] The above-mentioned first magnetic component 531 may also include multiple first magnets, which are evenly spaced around the optical axis, and the multiple first magnets are located on the same circle perpendicular to the optical axis; the second magnetic component 532 includes multiple second magnets, which are evenly spaced around the optical axis, and the multiple second magnets are located on the same circle perpendicular to the optical axis, the multiple first magnets and the multiple second magnets are arranged one by one along the optical axis direction, and the multiple first magnets and the multiple second magnets are opposite in polarity.

[0179] In a second possible implementation of the abutment drive assembly 53, the abutment drive assembly 53 may include multiple elastic members, which extend along the optical axis direction. The multiple elastic members are evenly spaced around the optical axis direction, and the multiple elastic members are located on the same circle perpendicular to the optical axis. One end of the elastic member is connected to the outer sleeve 4, and the other end of the elastic member is connected to the rotating sleeve 3. The elastic member can provide the rotating sleeve 3 with an elastic force to bear in the direction of the outer sleeve 4. The structure is simple and easy to implement.

[0180] The elastic member may be any one of a spring, a spring sheet, etc., which is not limited here.

[0181] In some embodiments, as Figure 14-16 As shown, the outer sleeve 4 includes a cylinder 43 and a reinforcement end cover 44 arranged on the light incident side of the cylinder 43. The reinforcement end cover 44 is provided with a third light hole 441 coaxial with the optical axis, and the second stop member 52 is provided on the reinforcement end cover 44.

[0182] In this way, the outer sleeve 4 can have better structural strength, and the second gear member 52 is arranged on the reinforced end cover 44. The second gear member 52 can be separately manufactured on the reinforced end cover 44, which simplifies the manufacturing process compared to the second gear member 52 being arranged on the outer sleeve 4 with the cylinder body 43.

[0183] Among them, the connection between the reinforcement end cover 44 and the cylinder 43 can be a bonding connection between the reinforcement end cover 44 and the cylinder 43, or a snap connection between the reinforcement end cover 44 and the cylinder 43, or a threaded connection between the reinforcement end cover 44 and the cylinder 43 by screws, which is not limited here.

[0184] In some embodiments, as Figure 14-16 As shown, a second magnet 45 is provided at one end of the outer sleeve 4 on the light incident side, and the second magnet 45 is used to install a polarization filter (not shown in the figure).

[0185] Thus, the polarization filter can be conveniently mounted on the lens module 110 through the second magnet 45 , so that the lens module 110 can capture images with bright colors.

[0186] A polarizing filter is a color filter that selectively allows light vibrating in a certain direction to pass through. The polarizing filter primarily comprises a lens body and a rear frame rotatably connected to the lens body. The rear frame is primarily made of carbon steel. The carbon steel rear frame can be attracted by the second magnet 45, allowing the polarizing filter to be conveniently attached to the light-entering end of the lens module 110, facilitating photography.

[0187] There can be multiple second magnets 45 , and the multiple second magnets 45 can be evenly spaced around the optical axis and arranged on one end of the light incident side of the outer sleeve 4 , so that the polarizing filter can be adsorbed and installed firmly and stably.

[0188] In other embodiments, Figure 17 and Figure 18 As shown, the lens module 110 also includes a focusing ring 6 and a clamping member 34. The focusing ring 6 is sleeved on the outside of the outer sleeve 4, and the focusing ring 6 is rotatably connected to the outer sleeve 4; one end of the clamping member 34 is connected to the focusing ring 6, and the other end is connected to the rotating sleeve 3 to drive the rotating sleeve 3 to rotate when the focusing ring 6 rotates.

[0189] Thus, the rotating sleeve 3 can be driven to rotate by rotating the adjusting ring. Compared with rotating the rotating sleeve 3 through the adjusting shaft connected to the rotating sleeve 3 and protruding from the outer peripheral wall of the outer sleeve 4, the rotating operation of the rotating sleeve 3 can be made convenient and comfortable.

[0190] Moreover, the adjusting ring is sleeved on the outer side of the outer sleeve 4, and can also protect the outer sleeve 4 to prevent foreign objects from scratching the outer sleeve 4.

[0191] In addition, the adjustment ring can be a metal adjustment ring, so that the adjustment ring has a better appearance, or the adjustment ring can be a plastic adjustment ring, which can reduce the weight of the lens module 110. This is not limited here.

[0192] The above-mentioned clamping member 34 can be implemented in various ways. For example, the clamping member 34 can be a protrusion arranged on the outer peripheral wall of the rotating sleeve 3, or a clamping shaft clamped on the outer peripheral wall of the rotating sleeve 3, or a stud threadedly connected to the outer peripheral wall of the rotating sleeve 3, which is not limited here.

[0193] In some embodiments, along the optical axis, the size of the outer sleeve 4 may be slightly smaller than the size of the rotating sleeve 3, that is, part of the rotating sleeve 3 may be exposed on the outer sleeve 4. At this time, the clamping member 34 can avoid the outer sleeve 4 and extend directly from the rotating sleeve 3 to the focusing ring 6, thereby preventing the clamping member 34 from interfering with the outer sleeve 4 when rotating under the drive of the focusing ring 6.

[0194] In other embodiments, Figure 17 As shown, the outer sleeve 4 is provided with an avoidance groove 46 extending along the circumference of the outer sleeve 4, and one end of the clamping member 34 is passed through the avoidance groove 46 and is slidably connected to the avoidance groove 46; a clamping structure 61 is provided on the focusing ring 6, and one end of the clamping member 34 is clamped with the clamping structure 61 after passing through the avoidance groove 46.

[0195] Therefore, rotating the adjustment ring can drive the clamping member 34 to rotate relative to the outer sleeve 4, thereby driving the rotating sleeve 3 to rotate, and the clamping member 34 is inserted into the avoidance groove 46 and is slidably connected to the avoidance groove 46, so that the avoidance groove 46 can limit the rotation of the clamping member 34 to prevent the focusing ring 6 from being rotated at an excessive angle, causing the first sliding groove 32 on the rotating sleeve 3 to collide with the insertion portion 23, thereby causing the lens module 2 to shake.

[0196] The size of the avoidance groove 46 along the circumferential direction of the outer sleeve 4 may correspond to the extension size of the first sliding groove 32 , and may also correspond to the moving distance of the lens module 2 .

[0197] In addition, a mounting groove is provided on the outer peripheral wall of the outer sleeve 4, which extends along the optical axis, and one end is connected to the end of the avoidance groove 46, and the other end passes through the end of the outer sleeve 4 away from the light incident side, so that when the outer sleeve 4 is sleeved on the rotating sleeve 3, the clamping part 34 connected to the rotating sleeve 3 can be slidably passed through the mounting groove on the outer sleeve 4, and finally slide into the avoidance groove 46, so that the installation operation of the outer sleeve 4, the clamping part 34 and the rotating sleeve 3 is convenient and quick.

[0198] Alternatively, as Figure 19-20 As shown, the clamping structure 61 is a clamping hole 611 or a clamping groove 612 , and when the clamping structure 61 is the clamping groove 612 , the clamping groove 612 is provided on the inner wall of the focus ring 6 .

[0199] Therefore, when the snap-fit structure 61 is a snap-fit hole 611, the snap-fit component 34 can be inserted into the snap-fit hole 611, which can effectively prevent the snap-fit component 34 from detaching from the adjustment ring when rotating the focus ring 6, thereby preventing the rotating sleeve 3 from failing to rotate; when the snap-fit structure 61 is a snap-fit groove 612, and the snap-fit groove 612 is arranged on the inner wall of the focus ring 6, the snap-fit component 34 can be hidden in the focus ring 6, so that the lens module 110 can have a better appearance.

[0200] Among them, along the circumference of the focus ring 6, the sizes of the clamping hole 611 and the clamping groove 612 match the sizes of the clamping part 34 to prevent the clamping part 34 from having a gap with the focus ring 6 in the circumference of the focus ring 6, that is, in the rotation direction of the focus ring 6, resulting in the clamping part 34 being able to rotate only when the focus ring 6 is rotated to a certain angle, thereby avoiding the user's experience being reduced due to the fact that the clamping part 34 can only be driven to rotate after the focus ring 6 is rotated to a certain angle.

[0201] Alternatively, as Figure 21 As shown, the lens module 110 further includes a support member 7 , one end of the support member 7 is connected to the base sleeve 1 , and the other end of the support member 7 is rotatably connected to the focus ring 6 .

[0202] As a result, the focusing ring 6 can be rotatably connected to the base sleeve 1 through the support 7, preventing the base sleeve 1 from being damaged by friction due to the rotation of the focusing ring 6, and avoiding the influence of friction damage on the rotation of the rotating sleeve 3, thereby avoiding the influence on the focus of the lens module 2.

[0203] Among them, the support member 7 can be a tubular structure mounted on the outer sleeve 4, and the outer diameter of the tubular structure support member 7 is the same as the outer diameter of the focusing ring 6, or the support member 7 can be a plurality of support protrusions detachably connected to the base sleeve 1, which is not limited here.

[0204] In addition, one end of the support member 7 is connected to the base sleeve 1. The support member 7 and the base sleeve 1 can be bonded together, or they can be threadedly connected by screws, or they can be snap-connected together, which is not limited here.

[0205] In some embodiments, as Figure 22 As shown, a third magnet 8 and a lower cover 9 are provided at one end of the base sleeve 1 away from the lens. The third magnet 8 is provided between the base sleeve 1 and the lower cover 9. The third magnet 8 is used for mounting the lens module 110 and the main body of the electronic device.

[0206] Therefore, the lens module 110 can be conveniently mounted on the main body of the electronic device through the magnetic adsorption of the third magnet 8 , thereby simplifying the mounting process of the lens module 110 and the main body of the electronic device.

[0207] In addition, the third magnet 8 is arranged between the base sleeve 1 and the lower cover 9, and the third magnet 8 can be hidden between the base sleeve 1 and the lower cover 9, thereby preventing the third magnet 8 from accidentally slipping and being lost.

[0208] There can be multiple third magnets 8 , which are evenly spaced around the optical axis between the base sleeve 1 and the lower cover 9 , so that the lens module 110 and the main body of the electronic device can be installed more firmly and stably.

[0209] Optionally, the above-mentioned lens module 2 can be a lens module 2 with a telephoto lens, so that when the rotating sleeve 3 is rotated, the insertion portion 23 slides along the first sliding groove 32 on the rotating sleeve 3 to drive the lens module 2 to move along the optical axis, so that the lens module 2 can be adjusted to different focal length positions, thereby enabling the lens module 110 to capture images of better quality.

[0210] Optionally, the top of the rotating sleeve 3 is provided with a first light hole 31, and the top of the outer sleeve 4 is provided with a second light hole 41, so that light can pass through the second light hole 41 and the first light hole 31 to reach the lens assembly 22. The supporting seat 21 supporting the lens assembly 22 and the bottom of the base sleeve 1 are also provided with light holes coaxial with the first light hole 31 and the second light hole 41, so that light can reach the photosensitive chip after passing through the lens assembly 22, so as to achieve the purpose of shooting.

[0211] In addition, when the lens module 110 is an interchangeable lens, that is, when the lens module 110 is detachably arranged on an electronic device (such as a mobile phone, a laptop computer, etc.), a photosensitive chip for receiving light and converting light into an electrical signal can be arranged on the outside of the lens module 110. At this time, the lower cover 9 of the lens module 110 is also provided with a light hole coaxial with the first light hole 31 and the second light hole 41. The photosensitive chip can be arranged at a position opposite to the light hole on the electronic device. After the external light passes through the lens assembly 22, it can reach the photosensitive chip, and when the focusing ring 6 is manually rotated or the sleeve 3 is rotated, the lens assembly 22 can be moved along the direction of the optical axis to adjust the distance between the lens assembly 22 and the photosensitive chip, thereby achieving the purpose of adjusting the focal length.

[0212] Example 2

[0213] This embodiment also provides an electronic device, Figure 23 As shown, it includes a main body 120, a lens module 110 of any one of the first embodiments, and a photosensitive chip. The lens module 110 is detachably arranged on the main body 120, and the photosensitive chip is arranged on the main body 120 and is located at the image side end of the lens module 110.

[0214] It should be explained that the image side end of the lens module 110 mentioned above refers to the end of the lens module 110 facing away from the object side.

[0215] In this embodiment, the lens module 110 is detachably arranged on the main body 120, so that the lens module 110 can be arranged on the electronic device 100 as an interchangeable lens, and the electronic device 100 can be combined with lens modules 110 with different focusing ranges, so that the shooting of the electronic device 100 can have the shooting effect of a SLR camera.
