When an element is referred to as being "connected" to another element, it can be directly connected to the other element or can have a middle element.

[0044] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0045] Please refer to Figure 1In an embodiment of the present application, a back support assembly 100 is provided, which comprises a back support bracket 10, a back support 20, and a locking assembly 30. The back support bracket 10 is configured to be connected with a photography shoulder support 200, and the photography shoulder support 200 is configured to mount a photography equipment. The back support 20 is rotationally connected with the back support bracket 10. The locking assembly 30 is arranged between the back support bracket 10 and the back support 20, and is configured to lock or unlock the relative rotation between the back support bracket 10 and the back support 20.

[0046] The back support bracket 10 serves as a basic component connected with the photography shoulder support 200, and plays a role in bearing and transmitting force, thereby ensuring the stable connection between the entire back support assembly 100 and the photography equipment. The back support 20 is rotationally connected with the back support bracket 10, so that the back support 20 can rotate relative to the back support bracket 10, and thus the angle can be flexibly changed according to the actual needs of the user.

[0047] The locking assembly 30 is configured to control the relative rotation state of the back support 20 and the back support bracket 10. When it is necessary to adjust the angle of the back support 20, the locking assembly 30 is unlocked, and the back support 20 can be freely rotated. When the angle is adjusted to a suitable angle, the locking assembly 30 plays a role, and increases the friction force or directly limits the rotation through mechanical structures (such as screw tightening, buckle clamping, etc.), thereby fixing the relative rotation between the back support bracket 10 and the back support 20, and making the back support 20 maintain a stable posture during shooting, thereby providing reliable support for the photography equipment.

[0048] Since the back support 20 is rotatable, the user can easily adjust the angle of the back support 20 according to different shooting scenes and personal physical conditions. Whether standing shooting, bending shooting, or half-squatting shooting, etc., the most comfortable and most stable angle for the equipment can be found, thereby greatly enhancing the adaptability in various shooting environments, achieving the most comfortable and stable support effect, and thus the user can maintain a good shooting state for a longer time, and the work efficiency is improved. Moreover, the locking assembly 30 can effectively prevent the back support 20 from rotating due to accidental collision, body shaking, etc. during shooting, thereby ensuring that the photography equipment always maintains at the expected position and angle, and reducing the shaking and displacement during shooting. For high-precision photography tasks (such as macro photography, long-focus lens shooting, etc.), the shooting quality can be significantly improved, and clearer and more stable pictures can be shot.

[0049] Please refer to Figure 2 In some embodiments, the back support assembly 100 further comprises:

[0050] The rotating assembly 40 comprises a rotating block 41 arranged on one of the back support bracket 10 and the back support 20, and a mounting groove 42 arranged on the other one of the back support bracket 10 and the back support 20. The rotating block 41 is located in the mounting groove 42 and can be driven to rotate around the central axis of the mounting groove 42.

[0051] The rotating block 41 is arranged on one of the back support bracket 10 or the back support 20, and the corresponding mounting groove 42 is arranged on the other one. When the rotating block 41 is located in the mounting groove 42, a rotating space around the axis of the mounting groove 42 can be obtained, and the mounting groove 42 provides a precise movement track and support for the rotating block 41, which can effectively reduce the jamming and resistance in the rotating process, so that the photographer can adjust the angle of the back support 20 more easily and accurately.

[0052] The rotating block 41 can rotate smoothly in the mounting groove 42 by external driving, such as manual force applied by the photographer, thereby driving the back support 20 to rotate relative to the back support bracket 10 to adjust the angle of the back support 20. After the back support 20 is rotated to a suitable angle by the rotating block 41, the locking assembly 30 locks the relative rotating state of the back support bracket 10 and the back support 20, so that they remain relatively stationary, ensuring the stability of the back support 20 during shooting.

[0053] In this embodiment, the design of the rotating block 41 and the mounting groove 42 makes the rotating connection between the back support 20 and the back support bracket 10 more compact, not only saving space, but also ensuring the mechanical strength and stability of the entire back support assembly 100. Compared with some complex rotating connection structures, the design of the rotating block 41 and the mounting groove 42 in this embodiment is more simple and efficient, reduces the risk of failure caused by too many parts, and improves the reliability of the back support assembly 100.

[0054] It should be noted that the rotating block 41 can be arranged on the back support bracket 10, and the mounting groove 42 can be arranged on the back support 20. Of course, the rotating block 41 can be arranged on the back support 20, and the mounting groove 42 can be arranged on the back support bracket 10, which can be set according to actual conditions.

[0055] Please refer to Figure 3 and Figure 4 In some embodiments, the mounting groove 42 is provided with a connecting column 421 arranged along the axis thereof, the connecting column 421 is provided with a connecting hole 422, the rotating block 41 is provided with a connecting shaft 411 matched with the connecting hole 422, and the connecting shaft 411 cooperates with the connecting hole 422 to connect the rotating block 41 and the mounting groove 42.

[0056] The connecting column 421 is arranged along the central axis of the mounting groove 42 and becomes the core support structure of the entire rotating connection. The connecting hole 422 on the connecting column 421 is matched with the connecting shaft 411 on the rotating block 41. When the connecting shaft 411 is inserted into the connecting hole 422, the connection between the rotating block 41 and the mounting groove 42 is realized. This connection not only provides a support point for the rotating block 41 to rotate around the central axis of the mounting groove 42, but also limits the degree of freedom of the rotating block 41 during rotation, so that it can only rotate around the central axis of the connecting column 421.

[0057] In this embodiment, the cooperation of the connecting shaft 411 and the connecting hole 422 provides stable support structure for the rotation of the rotating protrusion 41, making the connection between the back support 20 and the back support bracket 10 more reliable, and effectively reducing the shaking and deviation during rotation, ensuring that the back support 20 remains stable during rotation, improving the accuracy of angle adjustment. During shooting, even if the angle of the back support 20 needs to be adjusted frequently, the stability of the photographic equipment can be ensured, and the shooting effect is not affected by the shaking of the back support 20.

[0058] In addition, the design of the connecting shaft 411 and the connecting hole 422 facilitates production and manufacturing. In the production process, the connecting column 421, the connecting hole 422, the rotating protrusion 41 and the connecting shaft 411 can be accurately manufactured by using molds and other methods, improving production efficiency and product quality. At the same time, in the assembly process, the cooperation of the connecting shaft 411 and the connecting hole 422 is simple and intuitive, reducing the assembly difficulty and improving the assembly efficiency, which is conducive to reducing the production cost and improving the market competitiveness of the product.

[0059] Please refer to Figures 2 to 4 In some embodiments, the rotating protrusion 41 is provided on the back support 20, and the rotating protrusion 41 is provided with a plurality of first channels 412 in the radial direction. The mounting groove 42 is provided on the back support bracket 10, and the back support bracket 10 is provided with a second channel 11 communicating with the mounting groove 42.

[0060] The locking assembly 30 includes a resisting module 31 movably provided in the first channel 412 and a locking module 32 movably provided in the second channel 11. The resisting module 31 can extend into the second channel 11 through the first channel 412 to lock the rotating protrusion 41 and the mounting groove 42. The locking module 32 is used to drive the resisting module 31 to exit the second channel 11 to unlock the rotating protrusion 41 and the mounting groove 42.

[0061] The rotating protrusion 41 is provided on the back support 20, and the plurality of first channels 412 provided in the radial direction of the rotating protrusion 41 provides a moving space for the resisting module 31. The mounting groove 42 is located on the back support bracket 10, and the second channel 11 on the back support bracket 10 communicates with the mounting groove 42, which builds a channel basis for the cooperation of the resisting module 31 and the locking module 32. Moreover, the resisting module 31 and the locking module 32 are respectively arranged in the first channel 412 and the second channel 11, which fully utilizes the internal space of the back support 20 and the back support bracket 10, without increasing too much external volume and weight. It not only ensures the simplicity of the back support assembly 100 as a whole, but also does not affect the realization of its function, and is also convenient for installation and maintenance.

[0062] When it is necessary to lock the rotating lug 41 and the mounting groove 42, i.e., to fix the relative position of the backrest 20 and the backrest support 10, the second channel 11 is aligned with one of the first channels 412 by applying force to the rotating lug 41. At this time, the abutting module 31 can extend into the second channel 11 through the first channel 412, and the abutting module 31 interacts with the inner wall of the second channel 11 to form a frictional force or a clamping force, thereby limiting the rotation of the rotating lug 41 in the mounting groove 42, achieving the locking of the backrest 20 and the backrest support 10.

[0063] When it is necessary to unlock the rotating lug 41 and the mounting groove 42 in order to adjust the angle of the backrest 20, the locking module 32 plays a role. The locking module 32 drives the abutting module 31 to exit the second channel 11 by applying an external force (such as a manually operated lever, button, or other device). Once the abutting module 31 exits the second channel 11, the rotating lug 41 is no longer restricted and can freely rotate in the mounting groove 42, and the relative position of the backrest 20 and the backrest support 10 is unlocked, so that the angle can be adjusted.

[0064] The design of the locking assembly 30 of the present embodiment can provide efficient and reliable locking effect. Specifically, the design of the plurality of first channels 412 and the cooperating second channel 11 enables the abutting module 31 to lock the rotating lug 41 and the mounting groove 42 at multiple positions, increasing the stability and reliability of the locking. During the shooting process, even if subjected to a larger external force impact or vibration, the relative position of the backrest 20 and the backrest support 10 can be effectively fixed, ensuring the stability of the photographic equipment and improving the shooting quality.

[0065] In the present embodiment, the first channels 412 are provided in plurality, and the abutting module 31 is correspondingly provided in plurality. The provision of the plurality of first channels 412 provides different extension position options for the plurality of abutting modules 31, which can lock the backrest 20 at different positions according to actual needs, further enhancing the adjustability and flexibility of the backrest assembly 100. Photographers can choose the most suitable locking position according to different shooting scenes and body postures to obtain the best support and stability.

[0066] Please continue to refer to Figure 3 In some embodiments, the abutting module 31 includes an abutting piece 311 and a first reset piece 312, the abutting piece 311 is movably arranged in the first channel 412, and the first reset piece 312 acts on the abutting piece 311 to drive the abutting piece 311 to extend into the second channel 11 to be clamped.

[0067] The abutting member 311 is movable in the first channel 412, and the first reset member 312 serves as a power source to provide a continuous force to the abutting member 311. When the back support 20 needs to be locked with the back support bracket 10, the abutting member 311 moves along the first channel 412 to the second channel 11 under the action of the first reset member 312 until it extends into the second channel 11. At this time, the abutting member 311 is clamped with the inner wall of the second channel 11, thereby limiting the rotation of the rotating lug 41 in the mounting groove 42, and achieving the relative position fixation of the back support 20 and the back support bracket 10. When unlocking is needed, the locking module 32 overcomes the force of the first reset member 312 to drive the abutting member 311 to exit the second channel 11, so that the back support 20 and the back support bracket 10 can rotate relative to each other, and the unlocking operation is completed.

[0068] Further, the first reset member 312 is arranged to enable the abutting member 311 to automatically extend to the second channel 11 for clamping without external intervention, thereby achieving the automatic locking of the relative position of the back support 20 and the back support bracket 10. After adjusting the angle of the back support 20, the photographer does not need to perform additional operations to ensure the stability of the back support 20, thereby reducing the instability of the equipment due to careless operation and improving the convenience and stability of shooting. Moreover, the first reset member 312 continuously provides a force to the abutting member 311, so that the clamping force of the abutting member 311 in the second channel 11 is more stable and reliable. During shooting, even if a certain vibration or external force is applied, the action of the first reset member 312 can ensure that the abutting member 311 always remains in the clamped state and is not easily loosened, thereby effectively preventing the relative rotation between the back support 20 and the back support bracket 10, further improving the stability of the shooting equipment and ensuring the quality of the shooting picture.

[0069] Due to the automatic clamping function of the abutting member 311, the photographer does not need to perform complex locking operations during the operation process. After adjusting the angle of the back support 20, the abutting member 311 will automatically complete the clamping under the action of the first reset member 312, thereby greatly simplifying the operation process, saving time, and improving the shooting efficiency.

[0070] In the embodiment, the abutting module 31 cooperates with the abutting member 311 and the first reset member 312, which has a simple structure and is easy to produce and manufacture. Compared with some complex locking mechanisms, the structure requires fewer parts, has a lower cost, is convenient to maintain and repair, reduces the use cost, and improves the market competitiveness of the product.

[0071] Please continue to refer to Figure 3 In some embodiments, the locking module 32 includes a pressing member 321 and a second reset member 322. The pressing member 321 is movably arranged in the second channel 11 and is used to drive the abutting module 31 to exit the second channel 11. The second reset member 322 acts on the pressing member 321 to provide a force to reset the pressing member 321.

[0072] When the photographer needs to adjust the angle of the backrest 20, the pressing member 321 is pressed manually, and the pressing member 321 moves in the second channel 11 and contacts the abutting module 31 to apply a pushing force to the abutting module 31, so as to overcome the force of the first reset member 312 on the abutting member 311, and push the abutting member 311 back from the second channel 11 to the first channel 412, thereby releasing the locking state of the backrest 20 and the backrest support 10, and allowing the backrest 20 to rotate freely relative to the backrest support 10.

[0073] When the photographer releases the pressing member 321, the second reset member 322 applies a force to the pressing member 321 to reset the pressing member 321 to the initial position, so as to prepare for the next unlocking operation. In this way, through the cooperation of the pressing member 321 and the second reset member 322, the convenient unlocking and resetting functions of the backrest assembly 100 are realized.

[0074] In this embodiment, the photographer only needs to press the pressing member 321 to easily drive the abutting module 31 to exit the second channel 11 and realize the unlocking of the backrest 20, and the operation is very convenient. This simple and intuitive operation method reduces the operation difficulty of the user, and even a novice photographer who is not familiar with the device can quickly master the unlocking method, thereby improving the ease of use of the device. Moreover, the second reset member 322 enables the pressing member 321 to automatically reset after completing the unlocking operation, without the need for the photographer to manually reset the pressing member 321, thereby saving operation time and avoiding possible device failure or misoperation due to forgetting to reset the pressing member 321.

[0075] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the rotating block 41 is provided with a limiting groove 413, and the limiting groove 413 is formed with limiting end faces 414 at opposite ends in the rotating direction of the rotating block 41.

[0076] The limiting block 423 is arranged in the limiting groove 413 and used to abut against the limiting end faces 414 to limit the angle range of the rotating block 41 relative to the mounting groove 42.

[0077] When the rotating block 41 rotates in the mounting groove 42, as the rotation proceeds, the limiting block 423 will gradually approach the limiting end face 414 at both ends of the limiting groove 413. When the limiting block 423 abuts against the limiting end face 414 at one end, it will prevent the rotating block 41 from continuing to rotate in that direction, thereby limiting the rotation limit position of the rotating block 41 in that direction. Similarly, when rotating in the opposite direction, the limiting block 423 will abut against the limiting end face 414 at the other end, again limiting the rotation of the rotating block 41, and ultimately determining the angular range of rotation of the rotating block 41 relative to the mounting groove 42.

[0078] In this embodiment, through the design of the limiting groove 413 and the limiting block 423, the rotation angle range of the back support 20 relative to the back support bracket 10 can be accurately limited. Photographers can understand the maximum and minimum angles of rotation of the back support 20 in advance according to the shooting needs, so as to more accurately adjust the back support 20 to the appropriate position, improving the accuracy and professionalism of shooting.

[0079] Please refer to Figure 6 In some embodiments, the back support 20 includes a base 21 and a back support pad 22, and the rotating block 41 is connected to one side of the base 21, and the back support pad 22 is detachably connected to the other side of the base 21.

[0080] Among them, the rotating block 41 is connected to one side of the base 21, so that the back support 20 can realize the rotation function relative to the back support bracket 10 by cooperating the rotating block 41 with the mounting groove 42 on the back support bracket 10, meeting the needs of adjusting the position of the back support 20 under different shooting angles.

[0081] The detachable connection between the back support pad 22 and the other side of the base 21 not only takes into account the need to replace the back support pad 22 due to wear, dirt, and other reasons during use, but also allows users to choose back support pads 22 of different materials, thicknesses, or shapes according to their needs and preferences. For example, when shooting for a long time, users may choose a softer and thicker back support pad 22 to increase comfort; in a specific shooting environment, a back support pad 22 with special functions (such as waterproof and anti-slip) may be chosen.

[0082] In this embodiment, the back support pad 22 is detachably connected to the base 21, greatly facilitating the maintenance and replacement of the back support pad 22. If the back support pad 22 is dirty or damaged during use, the user can easily detach it for cleaning, repair, or replacement of a new back support pad 22, without the need to replace the entire back support 20, reducing the cost of use. Moreover, this detachable design allows users to customize the back support pad 22 according to their own needs and preferences, by replacing back support pads 22 of different materials, thicknesses, or shapes, users can find the most suitable comfort and support effect for themselves, improving the experience during shooting.

[0083] Further, the detachable back support pad 22 can be detached during transportation or storage, reducing the overall volume of the back support 20, facilitating packaging and transportation. At the same time, it can also avoid unnecessary extrusion and damage to the back support pad 22 during transportation and storage, improving the portability and durability of the equipment.

[0084] In some embodiments, the back support pad 22 is detachably connected to the base 21 by a magic tape; and / or,

[0085] The rotating block 41 is connected with a rotating seat 415, and the base 21 is connected with the rotating seat 415 through a rotating shaft 416, and the base 21 can be driven to oscillate relative to the rotating block 41; and / or,

[0086] A plurality of buffer members 417 are arranged between the rotating block 41 and the base 21.

[0087] The magic tape is composed of a hook surface and a velvet surface, and the back support pad 22 and the base 21 are respectively provided with the two surfaces. When the two surfaces are in contact and pressed together, the hooks of the hook surface will be hooked with the velvet of the velvet surface, thereby realizing the connection of the back support pad 22 and the base 21. When disassembly is needed, the hook surface and the velvet surface can be separated by applying a certain external force, achieving the purpose of detachability.

[0088] In this embodiment, the connection mode of the magic tape makes the replacement of the back support pad 22 extremely convenient. Users can quickly detach the old back support pad 22 and replace it with a new one according to different shooting scenes, personal preferences or the use of the back support pad 22, without the need for any tools, saving time and effort.

[0089] The rotating seat 415 is connected with the rotating block 41, providing a support point and a basis for rotation for the base 21. The base 21 is installed on the rotating seat 415 through the rotating shaft 416, and when subjected to external force, the base 21 can oscillate relative to the rotating block 41 within a certain range, thereby further increasing the flexibility of the angle adjustment of the back support 20.

[0090] In this embodiment, on the basis of the original rotating block 41 and the mounting groove 42 cooperating to realize rotation, the base 21 can also oscillate relative to the rotating block 41, making the back support 20 able to adapt to more complex shooting postures and angle requirements, providing photographers with more rich shooting angle options.

[0091] The buffer member 417 is usually elastic, and when the back support 20 is subjected to vibration, impact or collision due to angle adjustment during use, the buffer member 417 can absorb and disperse these energies, slow down the impact force through its own deformation, thereby protecting the connection structure between the rotating block 41 and the base 21, reducing the possibility of wear and damage.

[0092] In this embodiment, the buffer 417 can adopt a spring, and the elastic deformation of the spring can absorb and disperse the impact force generated during rotation, so that the rotation of the rotating block 41 is more stable. At the same time, due to the existence of the buffer 417, the rotating block 41 can float within a certain range, and can be adjusted in position on the base 21 in a small amplitude according to the actual situation, so as to be more fitted to the back of the photographer.

[0093] Please refer to Figure 7 The embodiment of the application also provides a photography shoulder support 200, which comprises a shoulder support body 201 and a back support assembly 100 as described above, and the back support assembly 100 is connected with the shoulder support body 201.

[0094] Among them, the shoulder support body 201 serves as the main bearing part of the whole device, providing shoulder support for the photographer, so that he can stably hold the photography equipment. And the back support assembly 100 is connected with the shoulder support body 201, which further enhances the stability and adaptability of the whole device. Through the cooperation of the shoulder support body 201 and the back support assembly 100, the photography shoulder support 200 can be flexibly adjusted according to the body posture of the photographer, the shooting angle requirement and other factors, providing stable support for the photography equipment and ensuring the smooth progress of shooting.

[0095] In this embodiment, after the back support assembly 100 is connected with the shoulder support body 201, a more stable support system is formed. The back support 20 can share part of the weight of the photography equipment, and work together with the shoulder support body 201 to make the photography equipment more stable during shooting, reduce the picture blur caused by shaking, and improve the shooting quality.

[0096] Further, the various angle adjustment functions of the back support assembly 100, such as rotation and swing, enable the photographer to easily adjust the angle of the photography equipment according to different shooting scenes and requirements. Whether it is to shoot a high-angle panorama, a low-angle close-up, or to shoot from different sides, the angle of the back support 20 and the shoulder support body 201 can be flexibly adjusted to achieve the shooting, greatly increasing the flexibility and creative space of shooting.

[0097] Traditional photography shoulder supports are often single-function, and if you want to realize two different support modes of back support and chest support, you usually need to equip two independent parts or adopt a more complex and fixed structure design. This not only increases the overall volume of the photography equipment, but also occupies a lot of space when carrying and storing, bringing great inconvenience to the photographer in outdoor shooting, mobile shooting and other scenes.

[0098] In order to solve the above technical problems, please refer to Figure 8 and Figure 9In some embodiments, the back support assembly 100 further comprises a connecting bracket 101, which is rotatably connected with the shoulder support body 201, and the back support bracket 10 is detachably connected with the connecting bracket 101.

[0099] It should be understood that the rotatable connection between the connecting bracket 101 and the shoulder support body 201 is based on the principle of mechanical rotation. When an external force is applied, the connecting bracket 101 can rotate relative to the shoulder support body 201. This rotational movement can change the position of the back support 20 in three-dimensional space, such as tilting up and down or swinging left and right.

[0100] Since the back support bracket 10 is detachably connected with the connecting bracket 101, the back support bracket 10 can be installed in a forward or reverse direction according to actual needs. When the back support function is needed, the back support bracket 10 is installed in reverse, and at this time the back support 20 can naturally fit the back (as shown in Figure 7 When the chest support function is needed, the back support bracket 10 is installed in the forward direction, and the back support 20 can fit the chest (as shown in Figure 8

[0101] At the same time, based on the rotatable connection between the back support 20 and the back support bracket 10, the back support 20 can also be adjusted between the horizontal and vertical directions to meet the needs of photographers in different shooting poses and environments.

[0102] The present embodiment solves the problem of single support mode and inconvenient switching of traditional photography shoulder support by adjusting the installation direction of the back support assembly 100 and the rotational operation of the back support 20. Moreover, since no additional independent components are needed, the overall space occupied is reduced, greatly enhancing the portability of the photography equipment, making it easier for photographers to carry and transport equipment in outdoor shooting, mobile shooting and other scenarios, reducing the burden and improving work efficiency.

[0103] Further, the rotatable connection between the connecting bracket 101 and the shoulder support body 201 enables the back support assembly 100 to be angle-adjusted in multiple directions, and the photographer can easily adjust the position of the back support 20 according to different shooting angle needs. The detachable connection between the back support bracket 10 and the connecting bracket 101 also provides additional possibilities for angle adjustment, such as replacing the connecting bracket 101 of different shapes or sizes to change the adjustment range and method of the back support 20, providing photographers with more personalized angle adjustment options.

[0104] In addition, the detachable connection design allows the photographer to detach the back support bracket 10 when not in use. This can greatly reduce the size of the entire photography equipment, making it easier to put into a photography bag or other storage equipment, reducing the burden, while also better protecting the photography equipment and avoiding damage due to collisions during transportation. ​

[0105] Please refer to Figure 10 In some embodiments, one of the back support bracket 10 and the connecting bracket 101 is provided with a sliding groove 102, and the other is provided with a sliding block 103 matched with the sliding groove 102. The sliding block 103 and the sliding groove 102 are in sliding fit to make the back support bracket 10 slide relative to the connecting bracket 101.

[0106] The back support assembly 100 further comprises a locking structure 104 for locking the back support bracket 10 and the connecting bracket 101.

[0107] In this embodiment, the sliding fit between the back support bracket 10 and the connecting bracket 101 is achieved through the design of the sliding groove 102 and the sliding block 103. When one component is provided with a sliding groove 102 and the other is provided with a sliding block 103 matched therewith, the sliding block 103 can smoothly slide in the sliding groove 102. This design is based on the principle of mechanical sliding. The sliding groove 102 provides a guide and motion trajectory for the sliding block 103, so that the back support bracket 10 can linearly slide relative to the connecting bracket 101 within a certain range. Through this sliding mode, the photographer can flexibly adjust the relative position between the back support bracket 10 and the connecting bracket 101 according to actual needs, thereby further optimizing the position and angle of the back support 20 to better adapt to different shooting postures and scenes.

[0108] After the back support bracket 10 is slid to the appropriate position, the locking structure 104 fixes the back support bracket 10 and the connecting bracket 101 together to prevent them from moving relative to each other due to external force or vibration during shooting. The locking structure 104 usually adopts a mechanical locking method, such as tightening with a bolt, clamping with a buckle, etc. Taking the bolt locking as an example, when the back support bracket 10 is slid to the desired position, the bolt is tightened to generate pressure that tightly fixes the back support bracket 10 and the connecting bracket 101 together, thereby ensuring that the relative position between them remains stable.

[0109] In this embodiment, the sliding fit of the sliding groove 102 and the sliding block 103 provides more possibilities for the position adjustment of the back support bracket 10. The photographer can not only adjust the angle through the rotation of the connecting bracket 101 and the shoulder support body 201 and the rotation of the back support 20, but also change the position of the back support 20 through the sliding of the back support bracket 10 relative to the connecting bracket 101. This multi-dimensional adjustment method greatly enhances the flexibility of the back support assembly 100 and can better meet the precise requirements for the position and angle of the back support 20 in different shooting scenes.

[0110] The locking structure 104 can reliably fix the back support bracket 10 and the connecting bracket 101 together after the back support bracket 10 is adjusted to a suitable position. During the shooting process, the photographic equipment may be affected by various external forces, such as slight shaking when handheld shooting, external environmental vibration, etc. The locking structure 104 can effectively prevent the relative movement between the back support bracket 10 and the connecting bracket 101, thereby ensuring that the back support 20 can continuously and stably provide support for the photographic equipment, and improving the stability of shooting and the picture quality.

[0111] Further, the design of the sliding groove 102 and the sliding block 103 makes the sliding operation of the back support bracket 10 simple and intuitive. Photographers can easily push the back support bracket 10 to slide in the sliding groove 102, and quickly find a suitable position of the back support 20. The operation of the locking structure 104 is also generally convenient, such as tightening and loosening of the bolts, or opening and closing of the buckles, which can be completed in a short time, and the photographers can quickly adjust the back support assembly 100 between different shooting scenes.
