[0030] The present disclosure provides a capture device, which refers to various tools and technical equipment configured to capture still images or dynamic videos. Capture devices are widely used in a variety of fields, including photography, filmmaking, television broadcasting, video production, and content creation in daily life. Capture devices can include mobile phones, still cameras, video cameras, action cameras, and the like.

[0031] Camera equipment typically includes a bracket and a cover. The bracket is used to mount a lens module, and the cover is used to cover and protect the lens module. The cover and bracket can rotate relative to each other to facilitate assembly and disassembly, facilitating maintenance of the lens module. In some technical solutions, the cover and bracket are connected via a snap-fit ​​structure, which has poor position stability and can easily cause the cover to tilt relative to the bracket, affecting the use of the camera.

[0032] Reference Figure 7 、 Figure 8 and Figure 9 In some possible embodiments of the present disclosure, a support 100 of a photographing device includes a storage space 120, a lens module is disposed within the storage space 120, and a cover 200 and the support 100 rotate relative to each other for assembly or disassembly. When the cover 200 is assembled with the support 100, it can cover the storage space 120, thereby protecting the lens module in the storage space 120. The cover 200 may be a part of the photographing device or an external structure of the photographing device.

[0033] In the disclosed embodiment, the bracket 100 can be fixed to the housing of the camera device, or the bracket 100 can form a part of the housing of the camera device. One end of the bracket 100 along the rotation axis L is provided with a mounting structure such as a mounting hole, which is used to mount the lens module. The cover 200 can be assembled to the end of the bracket 100 provided with the mounting structure, thereby covering and protecting the lens module.

[0034] It should be noted that the cover 200 can be a light shield made of a non-transparent material, or it can be at least partially translucent, that is, when the cover 200 is assembled on the bracket 100, the lens module can still achieve shooting. The cover 200 is used to provide protection against dust, water, collision, damage and scratches. Figure 2 、 Figure 4 、 Figure 5 and Figure 6 In a possible embodiment of the present disclosure, the cover body 200 is formed with a through hole, and a light-transmitting member 600 is embedded in the through hole. The light-transmitting member 600 is arranged opposite to the lens module.

[0035] In the embodiments of the present disclosure, the cover 200 and the bracket 100 can be assembled or disassembled relative to each other, and the two can be assembled and disassembled by relative rotation or by relative sliding. The relative rotation and disassembly of the two can be achieved by means of a snap connection or a threaded connection. In some possible embodiments of the present disclosure, both the cover 200 and the bracket 100 are provided with a threaded structure, and the two can be assembled or disassembled by the threaded structure. When the cover 200 and the bracket 100 are assembled in place, the threaded structure can limit the relative movement of the cover 200 and the bracket 100 along the assembly direction X. In some embodiments, the light-transmitting member 600 and the cover 200 can be integrally formed.

[0036] In which, the assembly direction X is a direction parallel to the rotation axis L of the cover body 200 and the bracket 100, and the threaded structure includes an internal thread set on the cover body 200 and an external thread set on the bracket 100; or, the threaded structure includes an internal thread set on the bracket 100 and an external thread set on the cover body 200.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The embodiment of the present disclosure also provides an installation structure, which includes a locking structure 300. The locking structure 300 includes a limiting recess 310 and a limiting member 320 respectively arranged on the cover body 200 and the bracket 100. The limiting member 320 includes a limiting protrusion 321 that can extend into or out of the limiting recess 310.

[0038] In the embodiment of the present disclosure, the locking structure 300 includes a limiting recess 310 and a limiting member 320, and the limiting recess 310 and the limiting member 320 are respectively arranged on the cover body 200 and the bracket 100, that is, one of the limiting recess 310 and the limiting member 320 is arranged on the cover body 200, and the other of the limiting recess 310 and the limiting member 320 is arranged on the bracket 100.

[0039] In one embodiment, the limiting recess 310 is provided on the cover 200, and the limiting member 320 is provided on the bracket 100. In another embodiment, the limiting recess 310 is provided on the bracket 100, and the limiting member 320 is provided on the cover 200. The following description uses the example in which the limiting protrusion 321 is connected to the bracket 100 and the limiting recess 310 is connected to the cover 200.

[0040] It should be noted that the limiting recess 310 and the limiting protrusion 321 can be located on the end surfaces of the cover 200 and the bracket 100, respectively, along the assembly direction X. Alternatively, when the bracket 100 and the cover 200 are sleeved together, the limiting recess 310 and the limiting protrusion 321 can be located on the peripheral side surfaces of the cover 200 and the bracket 100, respectively. In one example, the limiting protrusion 321 and the limiting recess 310 are both located on the outer peripheral side of the cover 200; in another example, the limiting protrusion 321 and the limiting recess 310 are both located between the inner peripheral side of the cover 200 and the outer peripheral side of the bracket 100. The technical solution provided by the embodiment of the present disclosure is that during the assembly or disassembly process of the bracket 100 and the cover 200, the limiting protrusion 321 and the limiting recess 310 move relative to each other. When the two are aligned, the limiting protrusion 321 enters the limiting recess 310, and the inner wall of the limiting recess 310 abuts the limiting protrusion 321, thereby preventing the bracket 100 and the cover 200 from moving relative to each other, that is, locking the bracket 100 and the cover 200 relative to each other. Conversely, when the limiting protrusion 321 and the limiting recess 310 are misaligned, the bracket 100 and the cover 200 can be unlocked relative to each other, thereby facilitating the assembly or disassembly of the bracket 100 and the cover 200. The provision of the locking structure 300 can improve the connection stability between the bracket 100 and the cover 200 and reduce the possibility of the cover 200 tilting relative to the bracket 100.

[0041] In the disclosed embodiment, the stopper 320 can be elastically deformable. During assembly of the cover 200 and the bracket 100, the stopper 320 is constrained by the space between the cover 200 and the bracket 100, transitioning from a stable, undeformed state to a deformed state to accumulate elastic potential energy. In other embodiments, the stopper 320 may not be elastically deformable, and may accumulate the potential energy required for locking solely through positional changes between the structures. This can prevent the cover 200 and the bracket 100 from loosening or misaligning during assembly, and also make disassembly relatively easy.

[0042] In some possible embodiments of the present disclosure, the limiting member has elastic deformation capability. When the cover body 200 is assembled in place relative to the bracket 100, the limiting protrusion 321 of the limiting member 320 is opposite to the limiting recess 310. Under the action of elastic potential energy, the limiting member 320 recovers from the deformed state to the stable state, so that the limiting protrusion 321 enters the limiting recess 310, realizing the engagement between the limiting protrusion 321 and the limiting recess 310, thereby limiting the relative rotation of the cover body 200 and the bracket 100, that is, the locking structure 300 locks the relative rotation of the cover body 200 and the bracket 100.

[0043] When the cover 200 needs to be disassembled relative to the bracket 100, an external force is applied to the cover 200 and the bracket 100 to rotate in the opposite direction. The external force overcomes the elastic force of the limit member 320, causing the limit member 320 to switch from a stable state to a deformed state, and the limit protrusion 321 withdraws from the limit recess 310 to release the restriction of the locking structure 300 on the rotation of the cover 200 relative to the bracket 100, that is, the locking structure 300 unlocks the relative rotation of the cover 200 and the bracket 100.

[0044] In the embodiment of the present disclosure, the locking structure 300 locks or unlocks the relative rotation of the cover body 200 and the bracket 100 through the cooperation between the limiting protrusion 321 and the limiting recess 310. It can be understood that when the inner contour of the limiting recess 310 is adapted to the outer contour of the limiting protrusion 321, the limiting recess 310 can cover the outer contour of the limiting protrusion 321, and the limiting protrusion 321 and the limiting recess 310 can fit better, which not only facilitates the assembly or disassembly of the cover body 200 and the bracket 100, but also provides a stable locking effect when locking, reducing the possibility of the cover body 200 rotating crookedly relative to the bracket 100.

[0045] In the disclosed embodiment, the inner contour of the position-limiting recess 310 matches the outer contour of the position-limiting protrusion 321 and covers the outer contour of the position-limiting protrusion 321. Specifically, the outer contour of the position-limiting protrusion 321 is smaller than that of the position-limiting recess 310. When the cover 200 and the bracket 100 are assembled, the position-limiting protrusion 321 can completely enter the position-limiting recess 310. Furthermore, the shape of the position-limiting recess 310 is similar to that of the position-limiting protrusion 321. For example, both are regular or irregular shapes such as square, triangle, circle, or ellipse. This allows the position-limiting protrusion 321 and the position-limiting recess 310 to better fit and have a larger fitting area, thereby increasing the stability of the position-limiting structure.

[0046] Specifically, the limiting recess 310 is a limiting groove or a limiting hole, and the limiting recess 310 includes an open side for the limiting recess 310 to extend into, and the projection of the limiting recess 310 corresponding to the open side covers the projection of the limiting recess 310 corresponding to the open side.

[0047] In the embodiment of the present disclosure, the limiting recess 310 can be a limiting groove, which includes a groove bottom surface opposite to the open side and two groove side surfaces arranged adjacent to the groove bottom surface. The two groove side surfaces are arranged in sequence along the rotation direction R and enclose the groove bottom surface to form the limiting recess 310. When the cover body 200 and the bracket 100 are assembled in place, the limiting protrusion 321 enters the limiting recess 310 and abuts against the two groove side surfaces. The limiting groove can be open or closed at both ends along the groove side surfaces, and the present disclosure does not limit this.

[0048] In the embodiment of the present disclosure, the limiting recess 310 can be a limiting hole, and the axial direction of the limiting hole can be parallel to the assembly direction X, or can be set perpendicular to the assembly direction X, that is, the axial direction of the limiting hole is set along the radial direction of the shell. The radial cross-section of the limiting hole can be a regular or irregular shape such as a circle, square, ellipse, diamond, etc. When the cover body 200 and the bracket 100 are assembled in place, the limiting protrusion 321 enters the limiting recess 310 and abuts against the inner wall of the limiting hole. Among them, the limiting hole can be a blind hole or a through hole, which is not limited in comparison in the present disclosure.

[0049] In the disclosed embodiment, the projection of the limiting structure corresponding to the opening side is the projection of the limiting structure on a plane parallel to the opening side. For example, when the limiting structure is provided on the end surface of the cover body 200 along the assembly direction X, the limiting recess 310 and the limiting protrusion 321 correspond to the projection of the opening side, that is, the projection of the limiting recess 310 and the limiting protrusion 321 along the assembly direction X. When the limiting structure is provided on the circumferential side of the cover body 200, the limiting recess 310 and the limiting protrusion 321 correspond to the projection of the opening side, that is, the projection of the limiting recess 310 and the limiting protrusion 321 along the radial direction of the cover body 200.

[0050] Reference Figure 7 and Figure 8 In some possible embodiments of the present disclosure, the limiting member 320 is bent to form a limiting protrusion 321. The limiting concave portion 310 formed by the bending setting has a simple structure and can save materials. In addition, the limiting member 320 is set as an integral part, and the structural strength is high.

[0051] In the disclosed embodiment, the stopper 320 can be bent at an obtuse or acute angle to form a triangular stopper protrusion 321; alternatively, the stopper 320 can be bent in an arc shape to form a stopper protrusion 321 having an arcuate surface. The triangular structure and the arcuate surface not only facilitate contact with the stopper recess 310 but also provide guidance. Under the action of an external force, the triangular structure and the arcuate surface abut against the edge of the stopper recess 310, thereby guiding the stopper 320 to undergo elastic deformation and transition to a deformed state, thereby unlocking the relative rotation between the cover 200 and the bracket 100.

[0052] In the embodiment of the present disclosure, the limiting member 320 may be a plate-like structure or a rod-like structure to facilitate bending, wherein the radial cross-section of the rod-like structure may be a regular or irregular shape such as a circle, square, triangle, or trapezoid.

[0053] Reference Figure 7 and Figure 10In one possible embodiment of the present disclosure, the retaining member 320 is a plate-like structure that is bent to form a triangular retaining protrusion 321. The bent portion of the retaining member 320 is rounded, and the retaining recess 310 is a retaining groove with a radial cross-sectional profile that matches the retaining recess 310. This arrangement provides a larger contact area between the retaining protrusion 321 and the retaining recess 310, providing a better locking effect.

[0054] Reference Figure 8 and Figure 11 In another possible embodiment of the present disclosure, the stopper 320 is a cylindrical rod-shaped structure that is bent to form a triangular stopper protrusion 321. The bent portion of the stopper 320 is rounded, and the stopper recess 310 is a stopper hole with a square radial cross-section. The stopper hole is a through hole through which the stopper protrusion 321 passes. This configuration allows the cover 200 to be thinner, saving material, and the stopper hole can limit the rotation of the stopper 320.

[0055] Reference Figure 9 and Figure 12 In some other possible embodiments of the present disclosure, the end of the stopper 320 is gradually reduced in size to form a stopper protrusion 321. The stopper protrusion 321 is provided at the end of the stopper 320. The deformation direction of the stopper 320 is set along the central axis of the stopper 320. The stopper 320 can provide a more reliable elastic force when it is compressed or stretched than when it is bent, and it occupies less space, making it easier to assemble in a narrow space.

[0056] In the disclosed embodiment, the stopper 320 may be a columnar structure, and its radial cross-section may be a regular or irregular shape such as a circle, square, diamond, or ellipse. The stopper protrusion 321 may be a pyramidal structure formed by multiple planes, or a conical or hemispherical structure formed by arcuate surfaces, thereby facilitating the unlocking of the relative rotation between the housing and the bracket 100.

[0057] In addition, the limiting member 320 can also include an elastic part and a spherical structure. The elastic part drives the spherical structure to move through elastic deformation. The spherical structure forms a limiting protrusion 321, and the spherical structure is rotated to reduce friction, thereby reducing the wear between the limiting member 320 and the shell.

[0058] Reference Figure 5 and Figure 9 In another possible embodiment of the present disclosure, the stopper 320 is cylindrical in shape. A hemispherical stopper protrusion 321 is formed on the end of the stopper 320 away from the bracket 100. The stopper recess 310 is a hemispherical or cylindrical stopper hole, so that the stopper protrusion 321 and the stopper recess 310 are shaped to match each other. This arrangement allows the hemispherical surface to receive force more evenly and achieves linear contact with the housing, thereby reducing friction and wear.

[0059] Reference Figure 1 、 Figure 3 、 Figure 5 and Figure 6 In some possible embodiments of the present disclosure, the limiting recess 310 is provided on the cover body 200 , and the cover body 200 includes a mating surface 210 in contact with the limiting member 320 .

[0060] In the embodiment of the present disclosure, the mating surface 210 can be a circumferential surface or an end surface of the cover 200. When the limiting recess 310 is provided on the end surface of the cover 200, the mating surface 210 is the end surface of the cover 200 facing the bracket 100 along the rotation axis L. When the limiting recess 310 is provided on the outer circumference of the cover 200, the mating surface 210 is the outer circumference of the cover 200. When the limiting recess 310 is provided on the inner circumference of the cover 200, the mating surface 210 is the inner circumference of the cover 200. It can also be understood that the mating surface 210 is the surface of the cover 200 on which the limiting recess 310 is provided.

[0061] In the disclosed embodiment, the stopper 320 contacts the mating surface 210. Specifically, during assembly or disassembly of the cover 200 relative to the bracket 100, the stopper 320 elastically deforms under the restraint of the mating surface 210, causing the stopper protrusion 321 to contact and move relative to the mating surface 210. It is understood that the relative movement between the stopper protrusion 321 and the mating surface 210 may cause wear of the stopper protrusion 321 and / or the mating surface 210, thereby generating dust. This dust may enter the lens module, scratching or otherwise affecting the imaging of the lens module. Furthermore, wear of the paint layer on the surface of the cover 200 may also affect its lifespan and aesthetics.

[0062] Reference Figure 5 and Figure 6 In some possible embodiments of the present disclosure, the limiting protrusion 321 and the mating surface 210 are in high-pair fit, that is, the contact between the limiting protrusion 321 and the mating surface 210 is point contact or line contact. For example, the limiting protrusion 321 can be configured as a cone or a hemispherical shape. The mating surface 210 in the high-pair fit can be the end surface of the cover body 200 or the peripheral side surface of the cover body 200.

[0063] For example, the mating surface 210 is the end face of the cover 200, and the stopper protrusion 321 is a hemispherical structure. The contact between the two is point contact, resulting in a small contact area. This reduces the generation of dust during relative motion. This reduces the possibility of dust scratching the lens module or obstructing it, thereby affecting image quality. Furthermore, the placement of the stopper protrusion 321 on the end face reduces its radial space occupation on the cover 200, thereby reducing the radial dimensions of the mounting structure.

[0064] Reference Figure 1 and Figure 3In some other possible embodiments of the present disclosure, the mating surface 210 is a peripheral surface of the cover body 200, and the peripheral surface surrounds the rotation axis L of the cover body 200 and the bracket 100. Compared with the case where the mating surface 210 is set on the end surface, the mating surface 210 is set on the peripheral surface at a greater distance from the lens module, and the peripheral surface and the lens module are not opposite, which has less impact on the lens module. Even if dust is generated by the friction between the limit member 320 and the cover body 200, it is difficult to enter the lens module, thereby reducing the possibility of dust scratching the lens module or blocking the lens module, thereby affecting the shooting quality.

[0065] Reference Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 In some possible embodiments of the present disclosure, the limiting recess 310 is arranged on the cover body 200, the limiting member 320 also includes a connecting structure 322, the limiting protrusion 321 is connected to the bracket 100 through the connecting structure 322, and at least one of the limiting protrusion 321 and the connecting structure 322 is elastically arranged.

[0066] In the embodiment of the present disclosure, the connection structure 322 and the limiting protrusion 321 can be connected by integral molding, snap connection, threaded connection, interference fit, bonding, welding, riveting, fastener 500 connection, etc. For example, the connection structure 322 and the limiting protrusion 321 are integrally formed.

[0067] In the disclosed embodiment, the connection structure 322 and the bracket 100 can be connected by integral molding, snap-fitting, threaded connection, interference fit, bonding, welding, riveting, or connection with fasteners 500. In one example, the connection structure 322 and the bracket 100 are connected by fasteners 500 such as screws. In another example, the connection structure 322 and the bracket 100 are snap-fitted, and both the fastener 500 connection and snap-fitting are easy to disassemble, thereby facilitating the disassembly and maintenance of the limiter 320.

[0068] Reference Figure 5 and Figure 9 In a possible embodiment of the present disclosure, the connecting structure 322 is a cylindrical structure, the limiting protrusion 321 is arranged at the end of the connecting structure 322, and the connecting structure 322 is provided with a flange near the end of the limiting protrusion 321, and the bracket 100 is provided with a snap-fit ​​hole 113, the connecting structure 322 is accommodated in the snap-fit ​​hole 113, and the flange and the snap-fit ​​hole 113 are interference fit to achieve snap-fit ​​fixation between the two.

[0069] In the disclosed embodiment, the position-limiting member 320 can be elastically configured in whole or in part. In one example, the position-limiting protrusion 321 of the position-limiting member 320 is elastically configured. During assembly or disassembly of the cover 200 and the bracket 100, the position-limiting protrusion 321 undergoes elastic deformation to enter or exit the position-limiting recess 310. In another example, the connection structure 322 of the position-limiting member 320 is elastically configured. During assembly or disassembly of the cover 200 and the bracket 100, the connection structure 322 undergoes elastic deformation to allow the position-limiting protrusion 321 to enter or exit the position-limiting recess 310. In yet another example, both the position-limiting protrusion 321 and the connection structure 322 are elastically configured. During assembly or disassembly of the cover 200 and the bracket 100, both the position-limiting protrusion 321 and the connection structure 322 undergo elastic deformation to allow the position-limiting protrusion 321 to enter or exit the position-limiting recess 310.

[0070] The technical solution provided by the embodiment of the present disclosure sets a connecting structure 322 to facilitate the assembly of the limiting member 320 and the bracket 100, and one of the limiting protrusion 321 and the connecting structure 322 has an elastic setting to meet the elastic deformation requirement, and the structure is more flexible.

[0071] Reference Figure 7 and Figure 10 In some possible embodiments of the present disclosure, along the relative rotation direction R between the cover body 200 and the bracket 100, a connecting structure 322 is provided at one end of the limiting protrusion 321, and a bending portion 323 is provided at the other end of the limiting protrusion 321, and the bending portion 323 is bent in a direction away from the cover body 200.

[0072] In the embodiment of the present disclosure, the bending portion 323 is provided at the free end of the limiting member 320, that is, the bending portion 323 can move freely relative to the limiting protrusion 321. The limiting member 320 provided with the bending portion 323 can be a plate-like structure, a rod-like structure, etc., and the portion of the bending portion 323 that is bent relative to the limiting protrusion 321 can be chamfered. The bending portion 323 can prevent the limiting member 320 from being deformed after repeated use and thereby blocking the rotation of the cover body 200. In other words, it can prevent the bending portion 323 from tilting toward the rotation center of the cover body 200 after the limiting member 320 is deformed, and from entering the rotation trajectory of the cover body 200 during assembly, thereby preventing the cover body 200 from rotating. Setting the bending portion 323 away from the rotation center of the cover body 200 in advance can effectively avoid the above-mentioned problem.

[0073] According to the technical solution provided by the embodiment of the present disclosure, only one end of the limiting protrusion 321 is connected to the bracket 100 through the connecting structure 322, and the other end is freely set, thereby reducing constraints and facilitating the deformation of the limiting member 320. In addition, the setting of the bending portion 323 can guide the limiting member 320 away from the protruding structure on the cover body 200 during the relative rotation of the cover body 200 and the bracket 100, so as to reduce the possibility of the limiting member 320 causing rotation jamming.

[0074] Reference Figure 8 and Figure 11 In some possible embodiments of the present disclosure, the limiting member 320 includes at least two connecting structures 322 , and the at least two connecting structures 322 are arranged on both sides of the limiting protrusion 321 .

[0075] In the embodiment of the present disclosure, the two sides of the limiting protrusion 320 can be the two sides along the radial direction of the cover body 200, or the two sides of the limiting protrusion 320 can be the two sides along the circumferential direction of the cover body 200, or the two sides of the limiting protrusion 320 can be the opposite or adjacent two sides in other directions on the limiting protrusion 320.

[0076] Reference Figure 8 and Figure 11 In one embodiment, at least two connecting structures 322 are provided at both ends of the position-limiting protrusion 321 along the relative rotation direction R between the cover 200 and the bracket 100. Providing connecting structures 322 at both ends of the position-limiting protrusion 321 ensures a more balanced force on the position-limiting protrusion 321, and both ends are restricted, resulting in higher positioning accuracy and less likely to fail due to excessive deflection.

[0077] Reference Figure 8 and Figure 11 In one possible embodiment of the present disclosure, the limiting member 320 is a rod-shaped structure, the middle portion of the limiting member 320 is bent to form a limiting protrusion 321, and connecting structures 322 are provided at both ends of the limiting member 320 to be respectively fixed to the bracket 100. In another possible embodiment of the present disclosure, the limiting member 320 is a plate-shaped structure, the middle portion of the limiting member 320 is bent to form a limiting protrusion 321, and connecting structures 322 are provided at both ends of the limiting member 320 to be respectively fixed to the bracket 100.

[0078] Reference Figure 7 、 Figure 8 、 Figure 10 and Figure 11 In some possible embodiments of the present disclosure, the connecting structure 322 includes a first structural portion 3221 and a second structural portion 3222, the first structural portion 3221 is connected to the limiting protrusion 321, and the first structural portion 3221 and the second structural portion 3222 are arranged at an angle, wherein at least the second structural portion 3222 in the connecting structure 322 is connected to the bracket 100.

[0079] In the embodiment of the present disclosure, the first structural portion 3221 and the second structural portion 3222 form an angle, that is, the axial direction of the first structural portion 3221 and the second structural portion 3222 form an angle, or the surfaces where the first structural portion 3221 and the second structural portion 3222 form an angle. The angle between the first structural portion 3221 and the second structural portion 3222 can be an obtuse angle, an acute angle, a right angle, etc., and the present disclosure does not limit this.

[0080] In the embodiment of the present disclosure, at least the second structural portion 3222 of the connecting structure 322 is connected to the bracket 100 . The second structural portion 3222 may be connected to the bracket 100 , or both the first connecting portion and the second connecting portion may be connected to the bracket 100 .

[0081] Reference Figure 8 and Figure 11 In a possible embodiment of the present disclosure, the limiting member 320 is a rod-shaped structure, and a connecting structure 322 is provided at both ends of the limiting member 320. Taking one of the connecting structures 322 as an example, the first structure portion 3221 and the second structure portion 3222 are rod-shaped structures, and the axes of the two are arranged at right angles. The first structure portion 3221 and the second structure portion 3222 are both connected to the bracket 100 to limit the rotation of the limiting member 320 relative to the bracket 100.

[0082] Reference Figure 7 and Figure 10 In another possible embodiment of the present disclosure, the limiting member 320 is a plate-shaped structure, and the limiting member 320 is provided with a connecting structure 322. The maximum surface of the first structural part 3221 in the connecting structure 322 is perpendicular to the maximum surface of the second structural part 3222, and the maximum surface of the second structural part 3222 is connected to the end face of the bracket 100, which not only ensures the connection stability between the second structural part 3222 and the bracket 100, but also enables the first structural part 3221 to guide the limiting protrusion 321 to the peripheral side of the cover body 200.

[0083] The technical solution provided by the embodiment of the present disclosure, in which the first structural portion 3221 and the second structural portion 3222 are arranged at an angle, makes the connection structure 322 more flexible, facilitates the connection of the connection structure 322 with different surfaces on the bracket 100, and can achieve more directional limitation with the bracket 100 to improve the stability of the connection.

[0084] Reference Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In some possible embodiments of the present disclosure, the locking structure 300 further includes a latching protrusion 330 and a latching recess 340. The latching protrusion 330 is provided on at least one of the bracket 100 and the cover 200, and the latching recess 340 is provided on the other of the bracket 100 and the cover 200. When the cover 200 and the bracket 100 are assembled, the latching protrusion 330 extends into the latching recess 340 and abuts against the inner wall of the latching recess 340 along the assembly direction X, thereby limiting relative movement of the cover 200 and the bracket 100 along the assembly direction X.

[0085] The engaging protrusion 330 is provided on the end surface of the bracket 100 along the assembly direction X, and the engaging recess 340 is provided on the end surface of the cover 200 along the assembly direction X. Alternatively, when the bracket 100 and the cover 200 are telescopically engaged, the engaging protrusion 330 is provided on a circumferential side surface of the bracket 100 surrounding the rotation axis L, and the engaging recess 340 is provided on a circumferential side surface of the cover 200 surrounding the rotation axis L.

[0086] In one example, the snap-fit ​​protrusion 330 is arranged on the inner peripheral side of the bracket 100, and the snap-fit ​​recess 340 is arranged on the outer peripheral side of the cover body 200; in another example, the snap-fit ​​protrusion 330 is arranged on the outer peripheral side of the bracket 100, and the snap-fit ​​recess 340 is arranged on the inner peripheral side of the cover body 200.

[0087] Reference Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In one possible embodiment of the present disclosure, the cover 200 is sleeved onto the outer circumference of the bracket 100. Four engaging protrusions 330 are evenly arranged along the axial direction on the outer circumference of the bracket 100, and four engaging recesses 340 are correspondingly arranged on the inner circumference of the cover 200. Taking one set of engaging protrusions 330 and recesses 340 as an example, the engaging protrusions 330 are formed with engaging recesses 340. Along the circumference of the bracket 100, one end of the engaging recess 340 is provided with an opening, and the other end is provided with a limiting inner wall 341. When the cover 200 and the bracket 100 are assembled, the engaging protrusions 330 enter the engaging recess 340 through the opening. The engaging recess 340 abuts against the inner wall of the engaging recess 340 along the assembly direction X and the limiting inner wall 341 along the rotational direction R, thereby preventing over-assembly.

[0088] Because the assembly and disassembly directions of the engaging protrusion 330 and the engaging recess 340 are limited to only one degree of freedom in the rotational direction R, i.e., one direction of the rotational direction R is for assembly and the other for disassembly, while this allows for quick assembly and disassembly, it is prone to loosening and misalignment when the camera is subjected to external forces, resulting in an insecure assembly. Therefore, a locking structure 300 is required to prevent loosening and misalignment during assembly and facilitate disassembly.

[0089] Reference Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 In some possible embodiments of the present disclosure, a fixing structure 110 is provided on one side of the bracket 100 along the rotation axis L toward the cover body 200 , and the fixing structure 110 is detachably connected to the connecting structure 322 .

[0090] In the disclosed embodiment, the fixing structure 110 is used to detachably connect the bracket 100 to the connecting structure 322, such as by snapping, threading, fastener 500 connection, suction connection, etc. For example, the fixing structure 110 and the connecting structure 322 are connected by fasteners 500; alternatively, the fixing structure 110 and the connecting structure 322 are snapped together.

[0091] In the embodiment of the present disclosure, the fixing structure 110 can be provided on the end surface of the bracket 100 to make the end surface structure of the bracket 100 simpler and smoother. Alternatively, the fixing structure 110 can be provided protruding from the end surface of the bracket 100 to facilitate the positioning of the limiting protrusion 321 on the peripheral side of the cover 200. In addition, the fixing structure 110 can also be provided on the peripheral side of the bracket 100.

[0092] Reference Figure 7 and Figure 10 In a possible embodiment of the present disclosure, the fixing structure 110 includes a connecting hole 111 arranged on the end face of the bracket 100, and the second structural part 3222 of the plate-like structure is also correspondingly provided with a connecting hole 111. The fastener 500 passes through the connecting hole 111 between the bracket 100 and the second structural part 3222 to fix the limiter 320 to the bracket 100.

[0093] On this basis, the fixed structure 110 also includes a positioning column 114 arranged on the end face of the bracket 100. The positioning column 114 is parallel to the axis of the connecting hole 111. A corresponding positioning hole 3223 is opened on the second structural part 3222 of the plate-like structure. The positioning column 114 extends into the positioning hole 3223, which can guide the bracket 100 and the connecting hole 111 on the second structural part 3222 to be aligned, and the positioning column 114 and the positioning hole 3223 can also cooperate to limit the rotation of the limit member 320 relative to the bracket 100.

[0094] One of the positioning post 114 and the positioning hole 3223 can be chamfered to facilitate mutual guidance and cooperation between the two. There can be one or more positioning posts 114 and one or more positioning holes 3223, and multiple positioning posts 114 are matched with multiple positioning holes 3223 in a one-to-one correspondence. For example, there are two positioning holes 3223, which are symmetrically arranged around the connecting hole 111.

[0095] Reference Figure 8 and Figure 11 In another possible embodiment of the present disclosure, the fixing structure 110 protrudes from the end surface of the bracket 100 and is formed with a snap-fit ​​groove 112. The snap-fit ​​groove 112 is "L"-shaped, and the first structural portion 3221 and the second structural portion 3222 of the rod-shaped structure respectively extend into the snap-fit ​​groove 112.

[0096] Reference Figure 9 and Figure 12In another possible embodiment of the present disclosure, the fixing structure 110 protrudes from the end surface of the bracket 100 and is formed with a snap-fit ​​hole 113. The contour of the snap-fit ​​hole 113 is adapted to the connecting structure 322 of the columnar structure. The connecting structure 322 is snapped into the snap-fit ​​hole 113, and the limiting protrusion 321 protrudes from the outside of the snap-fit ​​hole 113.

[0097] In the embodiment of the present disclosure, the fixing structure 110 can be integrally formed and set on the bracket 100, or can be set on the bracket 100 by fasteners 500, clamping, bonding, welding, etc.

[0098] The technical solution provided by the embodiment of the present disclosure is to provide a fixing structure 110 , and the fixing structure 110 is detachably connected to the connecting structure 322 , so as to facilitate the disassembly and maintenance of the limiting member 320 relative to the bracket 100 .

[0099] It should be noted that the locking structure 300 can be provided as one or more, and the multiple locking structures 300 are evenly distributed around the rotation axis L. Figure 13 and Figure 15 In some possible embodiments of the present disclosure, there are two locking structures 300 , and the two locking structures 300 are centrally symmetrically distributed about the rotation axis L. This makes the forces on the cover 200 and the bracket 100 more balanced and improves the locking effect.

[0100] On this basis, the embodiment of the present disclosure further provides a lens assembly, referring to Figure 13 、 Figure 14 and Figure 15 The lens assembly includes the mounting structure and the elastic structure 400 of the embodiment of the present disclosure. The elastic structure 400 is arranged between the cover body 200 and the bracket 100.

[0101] In the disclosed embodiment, the elastic structure 400 is capable of elastically deforming to provide an elastic force, and the elastic structure 400 is elastically deformable at least along the rotation axis L of the cover 200 and the bracket 100. For example, the elastic structure 400 is elastically deformable not only along the rotation axis L but also along the radial direction of the cover 200.

[0102] In the disclosed embodiment, the elastic structure 400 can be connected to the cover 200 and the bracket 100 by snapping, bonding, or the like. For example, an annular receiving groove is formed on both the cover 200 and the bracket 100, and the elastic structure 400 is snapped into the receiving groove. The elastic structure 400 can be made of rubber, elastic plastic, or the like.

[0103] In the embodiment of the present disclosure, the elastic structure 400 can also be used as a sealing component. Specifically, the elastic structure 400 is arranged between the bracket 100 and the cover body 200, and surrounds the periphery of the accommodating space 120 of the bracket 100. The elastic structure 400 can be a ring-shaped sealing ring, a sealing gasket, etc. When the cover body 200 and the bracket 100 are assembled, the accommodating space 120 (that is, the area where the lens module is located) is sealed.

[0104] It is understandable that the elastic structure 400 is elastic, and elastic deformation of the elastic structure 400 can improve its contact tightness with the bracket 100 / cover body 200, thereby compensating for the small gap between the cover body 200 and the bracket 100 to improve the sealing effect.

[0105] In the technical solution provided by the embodiments of the present disclosure, the elastic structure 400 elastically deforms at least along the rotation axis L of the cover 200 and the bracket 100 to provide a driving force to move the cover 200 and the bracket 100 away from each other along the assembly direction X. When the cover 200 and the bracket 100 are assembled, this driving force can make the engagement protrusion 330 and the engagement recess 340 fit more tightly, and also facilitate the alignment of the limiting protrusion 321 and the limiting recess 310, thereby improving the locking effect of the locking structure 300. In addition, the elastic structure 400 also elastically deforms to fill the small gap between the cover 200 and the bracket 100, thereby sealing the accommodating space 120 (i.e., the area where the lens module is located).

[0106] On this basis, in some possible embodiments of the present disclosure, the shooting device further includes a lens module, the lens module is connected to the bracket 100, the bracket 100 includes an accommodating space 120, and the lens module is disposed in the accommodating space 120.

Four engaging protrusions 330 are evenly arranged along the axial direction on the outer periphery of the bracket 100, and four engaging recesses 340 are correspondingly arranged on the inner periphery of the cover 200. The engaging protrusions 330 and the engaging recesses 340 mate with each other to restrict movement of the cover 200 and bracket 100 along the assembly direction X. Furthermore, the locking structure 300 also includes a limiting member 320 and a limiting recess 310. Each component of the limiting member 320 is elastically configured and integrally formed.

[0109] Reference Figure 1 、 Figure 2 、 Figure 7 、 Figure 10 and Figure 13 In one possible embodiment of the present disclosure, a limiting recess 310 is disposed on the outer periphery of the cover 200.

The limiting recess 310 is a limiting groove with a radial cross-sectional profile that matches the limiting recess 310. Along the relative rotation direction R of the cover 200 and the bracket 100, a connecting structure 322 is disposed at one end of the limiting protrusion 321, and a bent portion 323 is disposed at the other end of the limiting protrusion 321. The bent portion 323 bends away from the cover 200. The connecting structure 322 includes a first structural portion 3221 and a second structural portion 3222. The maximum surface of the first structural portion 3221 is arranged perpendicular to the maximum surface of the second structural portion 3222, and the second structural portion 3222 is connected to the bracket 100. The fixing structure 110 includes a connecting hole 111 provided on the end surface of the bracket 100. The second structural portion 3222 is also provided with a corresponding connecting hole 111. The fastener 500 passes through the connecting holes 111 of the bracket 100 and the second structural portion 3222 to fix the limiter 320 to the bracket 100. The fixing structure 110 also includes a positioning post 114 provided on the end surface of the bracket 100. The positioning post 114 is parallel to the axis of the connecting hole 111. The second structural portion 3222 of the plate-like structure is provided with corresponding positioning holes 3223. There are two positioning holes 3223, which are symmetrically arranged around the circumference of the connecting hole 111.

[0110] Reference Figure 3 、 Figure 4 、 Figure 8 、 Figure 11 and Figure 14 In another possible embodiment of the present disclosure, a limiting recess 310 is provided on the outer circumference of the cover 200. The limiting member 320 is a cylindrical rod-shaped structure that is bent to form a triangular limiting protrusion 321. The bent portion of the limiting member 320 is rounded. The limiting recess 310 is a limiting hole with a square radial cross-section. The limiting hole is a through hole that allows the limiting protrusion 321 to pass through. Connecting structures 322 are provided at both ends of the limiting member 320 to be fixed to the bracket 100 respectively. The connecting structures 322 include a first structural portion 3221 and a second structural portion 3222 arranged at right angles. The fixing structure 110 protrudes from the end surface of the bracket 100 and is formed with a snap-fitting groove 112. The snap-fitting groove 112 is "L"-shaped. The first structural portion 3221 and the second structural portion 3222 of the rod-shaped structure respectively extend into the snap-fitting groove 112.

[0111] Reference Figure 5 、 Figure 6 、 Figure 9 、 Figure 12 and Figure 15In another possible embodiment of the present disclosure, a limiting recess 310 is provided on the end surface of the cover 200. The limiting member 320 is a cylindrical structure. A hemispherical limiting protrusion 321 is formed on the end of the limiting member 320 away from the bracket 100. The limiting recess 310 is a hemispherical or cylindrical limiting hole. The limiting protrusion 321 makes point contact with the mating surface 210. The fixing structure 110 protrudes from the end surface of the bracket 100 and is formed with a snap-fitting hole 113. The contour of the snap-fitting hole 113 matches the cylindrical connecting structure 322. The connecting structure 322 is snap-fitted into the snap-fitting hole 113, and the limiting protrusion 321 protrudes outside the snap-fitting hole 113.

[0112] The mounting structure of the above embodiment facilitates easy assembly and disassembly of the cover 200 and bracket 100. The retaining protrusion 321 and the retaining recess 310 provide a strong locking effect.
