The vertical groove barrel is sleeved outside the floating barrel. The cam barrel is sleeved outside the vertical groove barrel. The relative axial positions of the vertical groove barrel and the cam barrel are stable and unchanged. The cam barrel can rotate relative to the vertical groove barrel. A cam groove is provided on the barrel body of the cam barrel. A vertical groove extending along its axial direction is provided on the barrel body of the vertical groove barrel. The roller passes through the cam groove and the vertical groove and is connected to the floating barrel. Based on this, by rotating the cam barrel, the roller can be driven to axially move along the cam groove and the vertical groove, thereby driving the floating barrel and the optical lenses mounted on the floating barrel to axially move. However, the roller occupies a certain space in the radial direction of the lens structure, resulting in poor structural compactness and a large volume of the lens structure. Summary of the Utility Model

[0003] Embodiments of this application provide a lens structure and a camera, aiming to solve the problem that the roller occupies a certain space in the radial direction of the lens structure, resulting in poor structural compactness and a large volume of the lens structure.

The second through hole is provided at one end of the groove close to the linkage ring, and the fastener passes through the second through hole.

[0015] In some embodiments, the floating lens barrel includes a lens mounting part and a floating linkage part both in a ring shape. The floating linkage part is connected to one end of the lens mounting part and surrounds the outer periphery of the lens mounting part. The groove is provided on the end face of the floating linkage part facing the lens mounting part.

[0016] In some embodiments, along the axial direction of the floating lens barrel, the projection of the floating linkage part coincides with a part of the projection of the vertical groove barrel.

[0017] In some embodiments, an external thread is provided on the outer ring surface of the linkage ring.

[0021] For the lens structure provided by the embodiments of the present application, the floating lens barrel, the vertical groove barrel and the linkage ring are sleeved in sequence from inside to outside. The connection part of the linkage ring is slidably connected to the vertical groove of the vertical groove barrel, and the part of the connection part passing through the vertical groove is linked and connected to the floating lens barrel via a fastener. Based on this, by axially moving the linkage ring relative to the vertical groove, the floating lens barrel and the optical lens mounted on the floating lens barrel can be driven to axially move, so that the lens structure can realize the axial movement of the floating lens barrel with a simplified and optimized structural design. Moreover, since the connection part only occupies the existing inner space of the linkage ring and does not need to additionally increase the radial dimension of the lens structure; and since the fastener extends along the axial direction of the floating lens barrel and axially fastens the connection part and the floating lens barrel, there is no need to additionally increase the radial dimension of the lens structure either. Therefore, the structural design of the lens structure can be compacted, the structural compactness of the lens structure can be improved, the internal space requirement of the lens structure can be reduced, the radial dimension and volume of the lens structure can be compressed, which is beneficial to the miniaturization of the lens structure.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clear and understandable, the following will describe the present application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0032] In this application, unless otherwise clearly defined and limited, terms such as "installed", "connected", "linked", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In this application, "axial direction" refers to the extending direction of the central axis of the corresponding structure, "circumferential direction" refers to the surrounding direction of the outer peripheral surface of the corresponding structure, and "radial direction" refers to any diameter direction perpendicular to the central axis of the corresponding structure.

[0034] In some cases, the lens structure includes a floating lens barrel, a vertical groove barrel, a cam barrel, and a roller. The floating lens barrel is used to install optical lenses. The vertical groove barrel is sleeved outside the floating lens barrel. The cam barrel is sleeved outside the vertical groove barrel. The relative axial positions of the vertical groove barrel and the cam barrel are stable and unchanged. The cam barrel can rotate relative to the vertical groove barrel. The barrel body of the cam barrel is provided with a cam groove extending in a curve. The barrel body of the vertical groove barrel is provided with a vertical groove extending along its axial direction. The roller passes through the cam groove and the vertical groove and is connected to the floating lens barrel. Based on this, by rotating the cam barrel, the roller can be driven to axially move along the cam groove and the vertical groove, so as to drive the floating lens barrel and the optical lenses installed on the floating lens barrel to axially move. However, the roller will occupy a certain space in the radial direction of the lens structure, resulting in poor structural compactness and large volume of the lens structure.

[0035] Therefore, the embodiments of this application provide a lens structure, which can optimize and compact the structural design of the lens structure, can reduce the radial size and volume of the lens structure, and is beneficial to the miniaturization of the lens structure.

[0036] The following describes the specific implementation of this application in detail in combination with specific embodiments:

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, some embodiments of the present application provide a lens structure, including a floating lens barrel 10, a vertical groove barrel 20 and a linkage ring 30. The vertical groove barrel 20 is sleeved outside the floating lens barrel 10, and a vertical groove 21 extending along its axial direction is provided on the barrel wall of the vertical groove barrel 20; the linkage ring 30 is sleeved outside the vertical groove barrel 20, and a connecting portion 31 is convexly provided inside the ring of the linkage ring 30. The connecting portion 31 is slidably connected to the vertical groove 21 and is connected to the floating lens barrel 10 via a fastener (not shown in the figure) extending along the axial direction of the floating lens barrel 10.

[0038] It should be noted that the floating lens barrel 10 is in a cylindrical shape and is used for mounting optical lenses.

[0039] The vertical groove barrel 20 is in a cylindrical shape and is sleeved on the outer periphery of the floating lens barrel 10. The vertical groove barrel 20 can be connected to components other than the floating lens barrel 10 and the linkage ring 30 in the lens structure (such as the driving barrel below) to stabilize its installation position, especially the axial position of the vertical groove barrel 20 remains stable. A vertical groove 21 is provided on the barrel wall of the vertical groove barrel 20. The vertical groove 21 extends along the axial direction of the vertical groove barrel 20, and the vertical groove 21 penetrates the barrel wall of the vertical groove barrel 20 along the groove depth direction of the vertical groove 21.

[0040] The linkage ring 30 is in a ring shape and is sleeved on the outer periphery of the vertical groove barrel 20. At least one connecting portion 31 is provided inside the ring of the linkage ring 30. The connecting portion 31 extends along the radial direction of the linkage ring 30. The connecting portion 31 can be a convex block or a convex strip, etc. The shape of the connecting portion 31 can be but is not limited to a rectangle, a waist shape, etc. The connecting portion 31 passes through and is slidably connected to the vertical groove 21. The vertical groove 21 can constrain and guide the moving direction, moving path and moving stroke of the connecting portion 31. The part of the connecting portion 31 passing through the vertical groove 21 can be connected to the floating lens barrel 10 via a fastener, so that the linkage ring 30 is linked and connected to the floating lens barrel 10, so that the linkage ring 30 can drive the floating lens barrel 10 to move axially along the vertical groove 21. Among them, the fastener extends along the axial direction of the floating lens barrel 10, and the fastener axially fastens the connecting portion 31 and the floating lens barrel 10. Among them, the fastener can be but is not limited to bolts, pins, buckles, snap fasteners, etc.

[0041] The lens structure provided by the embodiment of the present application sleevingly arranges the floating lens barrel 10, the vertical groove barrel 20, and the linkage ring 30 in sequence from the inside to the outside, and enables the connecting portion 31 of the linkage ring 30 to be slidably connected to the vertical groove 21 of the vertical groove barrel 20, and enables the portion of the connecting portion 31 passing through the vertical groove 21 to be linked and connected to the floating lens barrel 10 via a fastener. Based on this, by axially moving the linkage ring 30 relative to the vertical groove 21, the floating lens barrel 10 and the optical lens mounted on the floating lens barrel 10 can be driven to axially move, so that the lens structure can realize the axial movement of the floating lens barrel 10 with a simplified and optimized structural design. Moreover, since the connecting portion 31 only occupies the existing inner space of the linkage ring 30 and does not require an additional increase in the radial dimension of the lens structure; and since the fastener extends axially along the floating lens barrel 10 and axially fastens the connecting portion 31 and the floating lens barrel 10, there is no need to additionally increase the radial dimension of the lens structure either; therefore, the structural design of the lens structure can be compacted, the structural compactness of the lens structure can be improved, the internal space requirement of the lens structure can be reduced, the radial dimension and volume of the lens structure can be compressed, which is beneficial to the miniaturization of the lens structure.

[0042] Among them, in some application scenarios, the axial movement of the floating lens barrel 10 and the optical lens mounted on the floating lens barrel 10 can change the focal length of the lens structure and change the shooting angle of view and the framing range. In this case, based on the setting of this embodiment, the lens structure can realize the axial movement of the floating lens barrel 10 with a simplified, optimized, and compacted structural design, so as to realize the zoom operation.

[0043] In other application scenarios, the axial movement of the floating lens barrel 10 and the optical lens (which can be a focusing lens) mounted on the floating lens barrel 10 can adjust the image distance and accurately align the focus with the subject, so as to obtain a clear image. In this case, based on the setting of this embodiment, the lens structure can realize the axial movement of the floating lens barrel 10 with a simplified, optimized, and compacted structural design, so as to realize the focusing (focusing) operation.

[0044] In other application scenarios, the axial movement of the floating lens barrel 10 and the optical lens mounted on the floating lens barrel 10 can change the axial length of the lens structure. In this case, based on the setting of this embodiment, the lens structure can realize the axial movement of the floating lens barrel 10 with a simplified, optimized, and compacted structural design, so as to realize the switching between the retracted state and the extended state, which is convenient for the storage and use of the lens structure.

[0045] Please refer to Figure 2 、 Figure 3 、 Figure 4 , in some embodiments of the present application, there are multiple connecting portions 31, and the vertical grooves 21 are arranged in one-to-one correspondence with the connecting portions 31.

[0046] It should be noted that there are at least two connecting parts 31. The number of vertical slots 21 is equal to the number of connecting parts 31, and the positions of the vertical slots 21 correspond to the positions of the connecting parts 31. Each connecting part 31 is slidably connected to each vertical slot 21 one by one. As Figure 2 shown, in some embodiments, there are three connecting parts 31 and three vertical slots 21. The three connecting parts 31 are slidably connected to the three vertical slots 21 one by one.

[0047] By adopting the above solution, the linkage ring 30 can be provided with multiple connecting parts 31, each connecting part 31 can be slidably connected to each vertical slot 21 one by one, and each connecting part 31 can be linked and connected to the floating lens barrel 10 via fasteners respectively. Based on this, multiple-point constraints can be formed between the vertical slot barrel 20 and the linkage ring 30 via multiple groups of connecting parts 31 and vertical slots 21, and multiple-point fixation can be formed between the floating lens barrel 10 and the linkage ring 30 via multiple connecting parts 31, thereby improving the smoothness of the axial movement of the linkage ring 30 driving the floating lens barrel 10, improving the positioning accuracy of the optical lens installed on the floating lens barrel 10, and improving the image quality and service performance of the lens structure. Moreover, the setting of multiple connecting parts 31 can also enable the linkage ring 30 and the floating lens barrel 10 to disperse the force, so as to reduce the risk of component wear or damage caused by excessive single-point force; it can also enhance the overall structural strength and connection strength of the lens structure, so as to enable the lens structure to reliably resist external impacts and vibrations; thus, the service life of the lens structure can be extended.

[0048] Of course, in other embodiments, there can be one connecting part 31.

[0049] Please refer to Figure 2 , in some embodiments of the present application, each connecting part 31 is arranged in a non-uniform angular circle.

[0050] It should be noted that when the linkage ring 30 is provided with multiple connecting parts 31, each connecting part 31 is arranged in a non-uniform angular circle, that is, non-circular array distribution. As Figure 2 shown, in some embodiments, there are three connecting parts 31, and the central angles between adjacent two connecting parts 31 are 90°, 120°, and 150° respectively, so that the three connecting parts 31 are arranged in a non-uniform angular circle.

[0051] By adopting the above solution, by arranging the connecting parts 31 in a circumferential manner with unequal angles, on the one hand, it is convenient to achieve anti-fool assembly among the linkage ring 30, the vertical groove cylinder 20, and the floating lens barrel 10. It can reduce the risk of incorrect assembly positions of the components of the lens structure, improve the assembly accuracy and efficiency of the lens structure, and improve the use reliability of the lens structure. On the other hand, an asymmetric stress dispersion method can be formed between the linkage ring 30 and the floating lens barrel 10, which can effectively disperse the stress from all directions, reduce the situation of excessive single-point force, and improve the overall mechanical stability, durability, and service life of the lens structure.

[0052] Of course, in other embodiments, the connecting parts 31 can be arranged in a circumferential manner with equal angles.

[0053] Please refer to Figure 2 , Figure 3 , Figure 4 , in some embodiments of the present application, the connecting part 31 is provided with a first through hole 311, and the fastener is inserted through the first through hole 311.

[0054] It should be noted that the connecting part 31 is provided with a first through hole 311, and the first through hole 311 is arranged at one end of the connecting part 31 away from the inner ring surface of the linkage ring 30, that is, at one end of the connecting part 31 close to the floating lens barrel 10. The first through hole 311 penetrates the connecting part 31 along the axial direction of the linkage ring 30, that is, the first through hole 311 is a through hole. The shape of the first through hole 311 is set according to the fastener. For example, the first through hole 311 can be a circular hole, a rectangular hole, etc. The fastener is integrally formed relative to the connecting part 31, and the fastener can be inserted through the first through hole 311 and is separately connected to the connecting part 31.

[0055] By adopting the above solution, by making the connecting part 31 be provided with a first through hole 311 and making the fastener be inserted through the first through hole 311 and be separately connected to the connecting part 31, on the one hand, the connecting part 31 and the fastener can be integrally formed and then separately connected, which is convenient for modular and standardized production of the linkage ring 30 and the fastener respectively. On the other hand, it allows the fastener to be connected and fixed to the connecting part 31 through a simple action (such as an insertion or screwing-in action), without complex welding or integral forming processes, thereby simplifying the assembly process between the fastener and the connecting part 31, promoting a clear connection interface and fastening points between the fastener and the connecting part 31, and improving the connection reliability and connection strength between the fastener and the connecting part 31.

[0056] Moreover, the first perforation 311 is disposed adjacent to the side of the connecting portion 31 away from the inner circumferential surface of the linkage ring 30. With this arrangement, on the basis that the connecting portion 31 can penetrate through the first perforation 311, the extending length of the connecting portion 31 in the radial direction of the linkage ring 30 can be minimized as much as possible, so as to compress the occupied space of the connecting portion 31 in the radial direction of the linkage ring 30, thereby improving the structural compactness of the lens structure, reducing the internal space requirement of the lens structure, compressing the radial dimension and volume of the lens structure, and facilitating the miniaturization of the lens structure.

[0057] Please refer to Figure 2 、 Figure 3 、 Figure 4 , in some embodiments of the present application, the floating lens barrel 10 is provided with a second perforation 11 extending along the axial direction of the floating lens barrel 10, and a fastener is inserted through the second perforation 11.

[0058] It should be noted that the floating lens barrel 10 is provided with a second perforation 11, and the second perforation 11 is disposed near the outer edge of the end face of the floating lens barrel 10. The second perforation 11 extends along the axial direction of the floating lens barrel 10, and the second perforation 11 can be a blind hole or a through hole. The shape of the second perforation 11 is set according to the fastener. For example, the second perforation 11 can be a circular hole, a rectangular hole, etc. The fastener is integrally formed relative to the floating lens barrel 10, and the fastener can be inserted through the second perforation 11 and is detachably connected to the floating lens barrel 10.

[0059] By adopting the above scheme, by providing the floating lens barrel 10 with a second perforation 11 and enabling the fastener to be inserted through the second perforation 11 and detachably connected to the floating lens barrel 10, on the one hand, the floating lens barrel 10 and the fastener can be integrally formed and then detachably connected, which is convenient for modular and standardized production of the floating lens barrel 10 and the fastener respectively. On the other hand, it is allowed that the fastener is connected and fixed to the floating lens barrel 10 through a simple action (such as an insertion or screwing action), without complicated welding or integral forming processes, thereby simplifying the assembly process between the fastener and the floating lens barrel 10, promoting a clear connection interface and fastening points between the fastener and the floating lens barrel 10, and improving the connection reliability and connection strength between the fastener and the floating lens barrel 10.

[0060] Moreover, the second perforation 11 is disposed adjacent to the outer circumferential surface of the floating lens barrel 10. With this arrangement, on the basis that the floating lens barrel 10 can be provided with the second perforation 11, the required radial dimension of the floating lens barrel 10 can be minimized as much as possible, thereby improving the structural compactness of the lens structure, reducing the internal space requirement of the lens structure, compressing the radial dimension and volume of the lens structure, and facilitating the miniaturization of the lens structure.

[0061] Of course, in other embodiments, the fastener may be integrally connected to the connecting portion 31, such that the first through hole 311 is omitted from the connecting portion 31; or, the fastener may be integrally connected to the floating lens barrel 10, such that the second through hole 11 is omitted from the floating lens barrel 10. In this case, the fastener may be, but is not limited to, a snap fastener, a plug fastener, etc.

[0062] Please refer to Figure 2 、 Figure 3 、 Figure 4 , in some embodiments of the present application, the floating lens barrel 10 is provided with grooves 12 corresponding one-to-one to the connecting portions 31. One end of the groove 12 close to the linkage ring 30 communicates with the outside of the floating lens barrel 10, and the connecting portion 31 is fitted into the groove 12.

[0063] It should be noted that the floating lens barrel 10 is provided with grooves 12. One end of the groove 12 close to the linkage ring 30 (i.e., one end of the groove 12 close to the outer cylindrical surface of the floating lens barrel 10) communicates with the outside of the floating lens barrel 10. The number of grooves 12 provided is equal to the number of connecting portions 31 provided, the setting position of the groove 12 corresponds to the setting position of the connecting portion 31, the connecting portion 31 is fitted into the groove 12 one-to-one, and the groove 12 can limit, position, and accommodate the connecting portion 31.

[0064] By adopting the above solution, the floating lens barrel 10 can limit, position, and accommodate the connecting portion 31 one-to-one through the groove 12. Based on this, on the one hand, it can provide precise guidance and positioning for the connection between the linkage ring 30 and the floating lens barrel 10, can quickly and accurately fit the connecting portion 31 into the groove 12 during assembly, can improve the assembly accuracy and assembly efficiency between the linkage ring 30 and the floating lens barrel 10, can reduce the risk of misalignment or shaking between the linkage ring 30 and the floating lens barrel 10, and can improve the connection stability and connection reliability between the linkage ring 30 and the floating lens barrel 10. On the other hand, a part of the connecting portion 31 can be accommodated in the groove 12, and the connecting portion 31 and the floating lens barrel 10 can share part of the space, thereby improving the structural compactness of the lens structure, reducing the internal space requirement of the lens structure, compressing the radial dimension and volume of the lens structure, and facilitating the miniaturization of the lens structure.

[0065] Please refer to Figure 2 、 Figure 3 、 Figure 4 , in some embodiments of the present application, the bottom of the groove 12 is provided with a second through hole 11 extending along the axial direction of the floating lens barrel 10. The second through hole 11 is provided at one end of the groove 12 close to the linkage ring 30, and the fastener passes through the second through hole 11.

[0066] It should be noted that in the embodiment where the floating lens barrel 10 is provided with both the groove 12 and the second through hole 11, the second through hole 11 can be provided at the bottom of the groove 12, especially at one end of the groove 12 close to the linkage ring 30 (i.e., one end of the groove 12 close to the outer cylindrical surface of the floating lens barrel 10).

[0067] By adopting the above solution, on the basis of obtaining the effects of the embodiment where "the floating lens barrel 10 is provided with the groove 12" and the embodiment where "the floating lens barrel 10 is provided with the second through hole 11", by arranging the second through hole 11 at one end of the groove 12 close to the linkage ring 30, the operation convenience of "assembling and disassembling the fastener along the axial direction of the floating lens barrel 10 to the second through hole 11" can be improved, thereby improving the assembling convenience and assembling efficiency of the floating lens barrel 10, the fastener, and the linkage ring 30.

[0068] Of course, in other embodiments, the second through hole 11 can be provided at other positions on the bottom of the groove 12, for example, at the middle part of the groove 12 along the radial direction of the floating lens barrel 10.

[0069] Please refer to Figure 2 、 Figure 3 、 Figure 4 , in some embodiments of the present application, the floating lens barrel 10 includes a lens mounting portion 13 and a floating linkage portion 14 that are both annular. The floating linkage portion 14 is connected to one end of the lens mounting portion 13 and surrounds the outer periphery of the lens mounting portion 13. The groove 12 is provided on the end face of the floating linkage portion 14 facing the lens mounting portion 13.

[0070] It should be noted that the lens mounting portion 13 is annular and is used for mounting optical lenses. The floating linkage portion 14 is also annular. The floating linkage portion 14 is connected to one end of the lens mounting portion 13 along the axial direction of the lens mounting portion 13. The floating linkage portion 14 surrounds the outer periphery of the lens mounting portion 13 and is used for constructing a connection with the connecting portion 31 of the linkage ring 30. Along the axial direction of the floating linkage portion 14, the end face of the floating linkage portion 14 facing the lens mounting portion 13 is provided with the above-mentioned groove 12.

[0071] By adopting the above solution, the floating lens barrel 10 can mount optical lenses through the lens mounting portion 13 and construct a connection with the linkage ring 30 through the floating linkage portion 14 surrounding the outer periphery of the lens mounting portion 13. Based on this, the structural design of the floating lens barrel 10 can be simplified and optimized.

[0072] Moreover, since a stepped space is formed at the connection between the floating linkage part 14 and the lens mounting part 13, by arranging the groove 12 on the end face of the floating linkage part 14 facing the lens mounting part 13, it is convenient to limit, position and accommodate the connecting part 31 via the groove 12. On this basis, it can be promoted that the connecting part 31 fitted in the groove 12 can share part of the space with the floating linkage part 14 locally, and the part exceeding the notch of the groove 12 can share the axial space with the lens mounting part 13. Based on this, the setting of the connecting part 31 basically does not need to additionally increase the radial dimension and axial dimension of the lens structure, so that the structural compactness of the lens structure can be improved, the internal space requirement of the lens structure can be reduced, the volume of the lens structure can be compressed, and the miniaturization of the lens structure can be facilitated.

[0073] Of course, in other embodiments, the floating lens barrel 10 can adopt other structural designs.

[0074] Please refer to Figure 2 、 Figure 3 、 Figure 4 , in some embodiments of the present application, along the axis of the floating lens barrel 10, the projection of the floating linkage part 14 coincides with part of the projection of the vertical groove barrel 20.

[0075] By adopting the above scheme, by making the projection of the floating linkage part 14 along the axis of the floating lens barrel 10 coincide with part of the projection of the vertical groove barrel 20 along the axis of the floating lens barrel 10, the floating linkage part 14 and the vertical groove barrel 20 can share part of the radial space, the space occupied by the floating lens barrel 10 and the vertical groove barrel 20 in the radial direction of the lens structure can be compressed, so that the required radial dimension and volume of the lens structure can be reduced, the internal space requirement of the lens structure can be reduced, the structural compactness of the lens structure can be improved, and the miniaturization of the lens structure can be facilitated.

[0076] Please refer to Figure 1 、 Figure 3 、 Figure 4 , in some embodiments of the present application, an external thread 32 is provided on the outer ring surface of the linkage ring 30. Among them, the external thread 32 can be but is not limited to a multi-start thread. Correspondingly, the lens structure can include a driving barrel (not shown in the figure). An internal thread is provided inside the driving barrel. The driving barrel is sleeved outside the linkage ring 30 and is in threaded connection with the linkage ring 30. The rotation of the driving barrel can drive the linkage ring 30 to move axially.

[0077] By adopting the above solution, by providing an external thread 32 on the outer ring surface of the linkage ring 30, it is convenient for the lens structure to be sleeved outside the linkage ring 30 and threadedly connected and matched with the linkage ring 30 through a driving cylinder provided with an internal thread, so as to drive the linkage ring 30 to drive the floating lens barrel 10 to axially move synchronously relative to the vertical groove 21 through the rotation of the driving cylinder. Based on this, it is convenient to realize the axial movement of the linkage ring 30, improve the operation convenience and controllability of the axial movement of the linkage ring 30, and improve the adjustment accuracy of the axial movement stroke of the linkage ring 30 and the floating lens barrel 10.

[0078] Of course, in other embodiments, other methods can be used to drive the linkage ring 30 to axially move. For example, a dial block can be provided on the outer periphery of the linkage ring 30 to directly drive the linkage ring 30 to axially move through the dial block.

[0079] Please refer to Figure 1 、 Figure 3 、 Figure 4 In some embodiments of the present application, one end of the vertical groove 21 in its extending direction communicates with the outside of the vertical groove cylinder 20. That is, one end of the vertical groove 21 in the axial direction of the vertical groove cylinder 20 communicates with the outside of the vertical groove cylinder 20.

[0080] By adopting the above solution, it is convenient to perform the cooperation between the linkage ring 30 and the vertical groove cylinder 20, the cooperation between the connecting portion 31 and the vertical groove 21, and the fastening operation of the connecting portion 31 and the floating lens barrel 10 by the fastener from the end side where the vertical groove 21 communicates with the outside of the vertical groove cylinder 20. Based on this, it is beneficial to improve the assembly convenience and assembly efficiency of the linkage ring 30, the vertical groove cylinder 20, and the floating lens barrel 10, thereby improving the assembly convenience and assembly efficiency of the lens structure.

[0081] Moreover, the design with one end of the vertical groove 21 open basically does not affect the guiding effect and restraining effect of the vertical groove 21 on the axial movement of the connecting portion 31, thereby maintaining the structural reliability and service performance of the lens structure.

[0082] Of course, in other embodiments, both opposite ends of the vertical groove 21 in its extending direction can communicate with the outside of the vertical groove cylinder 20.

[0083] Please refer to Figure 1 Some embodiments of the present application provide a camera, including the lens structure provided by the embodiments of the present application. The lens structure provided by the embodiments of the present application can be installed on the main body frame of the camera.

[0084] By adopting the above solution, the camera can adopt the lens structure provided by the embodiments of the present application to improve the overall structural compactness, compress the overall volume, and achieve the overall miniaturization and miniaturization.

[0085] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
