[0037] The present application provides a photography expansion accessory, which is mainly applied to a photography and videography shooting device.

[0038] Referring to Figure 1 and Figure 2 , in an embodiment of the present application, the photography expansion accessory comprises:

[0039] An expansion plate 10, the upper surface of the expansion plate 10 is used for mounting a photography and videography device, the lower surface of the expansion plate 10 is used for connecting with a photography and videography accessory, and the expansion plate 10 is provided with a containing cavity 20 penetrating through the upper and lower surfaces thereof; and

[0040] A mounting seat 30, the mounting seat 30 is connected with the expansion plate 10 and can be movably loaded into or exited from the containing cavity 20, and the mounting seat 30 is used for mounting a tracker 40.

[0041] In the present embodiment, the photographic expansion accessories include, but are not limited to, rabbit cages, handles, and shoulder supports, etc. Among them, the camera rabbit cage is a bracket device specially designed for cameras. Its shape is similar to a cage, which wraps the camera in it to provide protection for the camera. Its solid shell and buffer design can effectively resist external force impact, reduce repair or replacement costs, extend the service life of the camera, and provide expansion interfaces for the camera to adapt to the use of more accessories.

[0042] In the present embodiment, the expansion board 10 is the core component of the entire rabbit cage. High-strength and lightweight aluminum alloy or carbon fiber composite materials can be used to ensure the overall structure is solid without increasing the overall weight of the photographic and video equipment. The overall shape of the expansion board 10 is in line with the size of the photographic and video equipment, avoiding interference with the normal use of the photographic and video equipment.

[0043] The lower surface of the expansion board 10 is usually provided with a plurality of standardized interface structures. For example, it is equipped with a plurality of standard screw interfaces, such as 1 / 4 screw interfaces, cold shoe interfaces, and Arri positioning holes, etc. It is convenient to install various accessories, such as external microphones, LED lights, monitors, viewfinders, handles, etc. According to different shooting needs, it can be flexibly configured to improve the shooting effect and the diversification and professionalization of creation.

[0044] The upper surface of the expansion board 10 is provided with a mounting rod for directly connecting the photographic and video equipment. One end of the mounting rod is rotatably connected to the main body of the expansion board 10 and is provided with a rotating tool, for example, a thin sheet-shaped wrench. The other end is provided with a standard screw interface that can be quickly connected with the camera or other photographic and video equipment. A receiving cavity 20 is reserved on one side of the expansion board 10, which can accommodate the mounting seat 30 and ensure that the internal space is sufficient to avoid interference with the tracker 40 signal. At the same time, the tracker 40 is hidden in the expansion board 10, which does not affect the overall appearance of the expansion board 10. For example, the present application sets a receiving cavity 20 at the position of the expansion board 10 corresponding to the camera battery compartment. When the camera needs to replace the battery, the battery can pass through the receiving cavity 20 on the expansion board 10, without affecting the normal replacement of the battery. When the camera is normally used, the tracker 40 can also be set in the receiving cavity 20 by fully utilizing the space of the receiving cavity 20.

[0045] In this embodiment, the mounting base 30 is mainly used to fix the tracker 40. To avoid interference from metal materials on wireless signals, the mounting base 30 is made of high-strength engineering plastics (such as ABS or PC plastic) or other non-metallic materials with low electromagnetic shielding performance. Simultaneously, to enhance installation stability, soft cushioning materials such as rubber or silicone can be embedded inside. The mounting base 30 is designed as an independent component, with dimensions and shape matching the receiving cavity 20. Furthermore, the mounting base 30 is not limited to connection with the extension plate 10; it can also be connected to other photography and videography extension accessories such as handles and shoulder supports. The tracker 40 can be fixed to the mounting base 30 by threaded connection or by clips (vertical snap-in, angled snap-in, rotational snap-in).

[0046] The connection between the mounting base 30 and the extension plate 10 can be rigid or flexible. For example, the mounting base 30 can be connected to the extension plate 10 via a safety rope or fixed to the extension plate 10 with screws. The mounting base 30 can be movably inserted into or removed from the receiving cavity 20. During normal use, the mounting base 30 is fixed within the receiving cavity 20 of the extension plate 10. When installing or removing the tracker 40, the mounting base 30 needs to be detached from or exposed within the extension plate 10 for easy user installation and removal of the tracker 40. Specifically, the mounting base 30 and the extension plate 10 can be adjusted using threaded adjustment structures, sliding guides, magnetic attraction, and snap-fit ​​mechanisms, allowing for horizontal or vertical adjustment of the mounting base 30 relative to the extension plate 10, or separation of the mounting base 30 from the extension plate 10, during installation or removal of the tracker 40. For example, rotating the mounting base 30 around a rotation axis at a certain position within the extension plate 10 rotates the mounting base 30 to the removal position of the tracker 40. A fixing structure exists between the mounting base 30 and the expansion plate 10, so that when the mounting base 30 enters the receiving cavity 20, it can be fixed within the receiving cavity 20 of the expansion plate 10, preventing displacement due to vibration or improper operation. This also conceals the tracker 40, improving the space utilization of the expansion plate 10 and saving space. For example, the mounting base 30 is fixed by a snap-fit ​​and slot connection. The connection between the mounting base 30 and the expansion plate 10 makes the installation and removal of the tracker 40 more convenient. When the user needs to replace the battery, a simple operation is sufficient, requiring no additional tools.

[0047] Reference Figure 3 and Figure 4 As shown, in one embodiment, the mounting base 30 is rotatably connected to the expansion plate 10, so that the mounting base 30 can be rotated to be inserted into or removed from the receiving cavity 20; a locking structure 50 is provided between the mounting base 30 and the expansion plate 10, the locking structure 50 being used to lock the mounting base 30 when it is inserted into the receiving cavity 20.

[0048] In this embodiment, one side of the mounting base 30 is rotatably connected to the expansion plate 10 via a rotating structure, allowing the mounting base 30 to be inserted into or removed from the receiving cavity 20 by rotation. The support point for rotation can be located on the lower surface of the expansion plate 10 on one side of the receiving cavity 20, so that the mounting base 30 rotates open towards the lower surface of the expansion plate 10, i.e., away from the direction in which the expansion plate 10 is installed, ensuring that the mounting base 30 does not interfere with other components of the expansion plate 10 during rotation. Simultaneously, the tracker 40 can be installed and removed without removing the entire expansion plate 10 from the photographic equipment. The rotating structure can be a combination of a rotating shaft and a rotating hole. The rotating shaft can be located on the mounting base 30 or on the mounting base 30 itself; the corresponding rotating hole is located on another structure to mate with the rotating shaft. The design of the rotating shaft allows the mounting base 30 to rotate within a certain angle range (e.g., adjustable by 90°), enabling the mounting base 30 to quickly enter and exit the receiving cavity 20. The mounting base 30 is in the open state when it is removed from the receiving cavity 20 via the rotating shaft, and in the closed state when it is fixed inside the receiving cavity 20 by the locking structure 50. In the open state, the user can assemble and disassemble the tracker 40, and also replace the battery of the camera equipment. In the closed state, the tracker 40 can be concealed inside the expansion plate 10.

[0049] In this embodiment, a locking structure 50 is provided between the mounting base 30 and the expansion plate 10. The locking structure 50 is used to lock the mounting base 30 when it is inserted into the receiving cavity 20. The locking structure 50 can be located on the lower surface of the mounting base 30, i.e., the lower surface of the expansion plate 10, for easy user operation. The locking structure 50 can be disposed on the expansion plate 10 or the mounting base 30 on the other side of the receiving cavity 20, opposite to the rotating structure. One part of the locking structure 50 is disposed on the mounting base 30, and the other part is disposed on the expansion plate 10. The two parts cooperate to fix the mounting base 30 in the receiving cavity 20. For example, the locking mechanism can be fixed by a buckle and a slot connection. When the mounting base 30 rotates into the receiving cavity 20, the buckle enters the slot to achieve mechanical locking and prevent accidental rotation caused by external vibration or operation.

[0050] Reference Figure 3 and Figure 4 As shown, the locking structure 50 includes: a locking groove 51 disposed on one of the expansion plate 10 and the mounting base 30; and a locking assembly 52 disposed on the other of the expansion plate 10 and the mounting base 30. The locking assembly 52 is used to form a locking engagement with the locking groove 51 to lock the mounting base 30 or to release the locking engagement with the locking groove 51 to release the mounting base 30.

[0051] In the embodiment, the mounting seat 30 is effectively locked or released in the accommodating cavity 20 by the cooperation of the locking groove 51 and the locking assembly 52. The locking groove 51 is arranged on the lower surface of one of the expansion board 10 or the mounting seat 30, and is generally in the shape of a long rectangular groove, which is used to form a locking state in cooperation with the locking assembly 52. The depth and width of the locking groove 51 are sufficient for the locking assembly 52 to be firmly clamped, so as to avoid loosening due to vibration or improper operation during use. The locking assembly 52 is arranged on the other side of the expansion board 10 or the mounting seat 30 of the locking groove 51. The locking assembly 52 generally includes a resilient member, which moves the locking assembly 52 to the locking groove 51, so that the locking assembly 52 enters the locking groove 51, thereby realizing the locking effect. When locked, the locking assembly 52 is kept in the locking groove 51 by the resilient member; when unlocked, the user pushes the locking assembly 52 to move out of the locking groove 51, thereby releasing the cooperation between the two and allowing the mounting seat 30 to rotate freely on the expansion board 10. After the user releases the locking assembly 52, the locking assembly 52 will reset to the position when locked under the action of the resilient member. At this time, the mounting seat 30 is rotated to the locked position, so that the locking assembly 52 reenters the locking groove 51, and the locking is completed.

[0052] Referring to Figure 5 In an embodiment, the locking assembly 52 is arranged on the mounting seat 30, and the locking assembly 52 includes:

[0053] A locking switch 53 is slidably arranged on the mounting seat 30, and the surface of the locking switch 53 is configured with an operation part 531 protruding from the mounting seat 30. One end of the locking switch 53 is provided with a lock tongue part 532, which can extend into the locking groove 51 to form a locking cooperation or exit the locking groove 51 to cancel the locking cooperation with the locking groove 51 by sliding the locking switch 53.

[0054] A first resilient member 54 is arranged on the mounting seat 30 and acts on the locking switch 53. The first resilient member 54 is used to provide an elastic force for the sliding reset of the locking switch 53.

[0055] In the embodiment, the locking assembly 52 is arranged on the lower surface of the mounting base 30, and the locking slot 51 is arranged on the lower surface of the expansion board 10 relative to the locking assembly 52. The locking switch 53 in the locking assembly 52 is arranged on the mounting base 30 and can slide horizontally along the lower surface of the expansion board 10. For the convenience of description, the direction in which the locking switch 53 moves towards the locking slot 51 is defined as the front pushing direction, and the direction in which the locking switch 53 moves away from the locking slot 51 is defined as the rear pushing direction. The main body of the locking switch 53 is hidden in the mounting base 30, and the mounting base 30 is provided with a limiting through slot at the position of the lower surface corresponding to the locking switch 53. The surface of the locking switch 53 facing the limiting through slot is provided with a protruding operation part 531, and the operation part 531 slides in the limiting through slot, serving as the operation object of the user to drive the movement of the main body of the locking switch 53, thereby completing the locking and unlocking operations. Referring to Figure 5 As shown in the figure, the limiting through slot has an inclined surface in the front pushing direction of the operation part 531 of the locking switch 53, and the inclined surface is inclined towards the inside of the limiting through slot. In this way, the user can conveniently push the operation part 531 of the locking switch 53 in the rear pushing direction, thereby pushing the locking switch 53.

[0056] In the embodiment, the locking switch 53 is provided with a locking tongue part 532 at one end facing the locking slot 51, and the locking tongue part 532 can move with the locking switch 53. When the locking switch 53 is pushed in the front pushing direction to the limiting position of the limiting through slot, the locking tongue part 532 can extend into the locking slot 51 to fix the mounting base 30 and the expansion board 10. The first elastic member 54 is connected between the locking switch 53 and the mounting base 30, and the first elastic member 54 provides the elastic force for the movement of the locking switch 53. When the locking tongue part 532 is in locking cooperation with the locking slot 51, the first elastic member 54 always acts on the locking switch 53, so that the locking tongue part 532 always maintains in the locking slot 51. For example, the first elastic member 54 can be a spring. When the locking cooperation is released, the user pushes the operation part 531 of the locking switch 53 in the rear pushing direction, so that the locking tongue part 532 exits the locking slot 51. At this time, the user can take out the mounting base 30 from the accommodating cavity 20. Further, the cross section of the locking tongue part 532 is a right trapezoid, and the upper surface is horizontally arranged, and the lower surface is obliquely arranged. In this way, when the user puts the mounting base 30 into the accommodating cavity 20, the obliquely arranged lower surface of the locking tongue part 532 abuts against the expansion board 10, and the locking tongue part 532 is pushed backward through the expansion board 10. The user does not need to push the locking switch 53 in the rear pushing direction, but only needs to press the mounting base 30 to put it into the accommodating cavity 20.

[0057] Referring to Figure 5 As shown in the figure, in an embodiment, the expansion board 10 is provided with a connecting shaft 11, and the mounting base 30 is rotatably sleeved on the connecting shaft 11 to form a rotary connection with the expansion board 10. The connecting shaft 11 is sleeved with a second elastic member 12, and the second elastic member 12 acts on the mounting base 30 to provide the elastic force for the rotary reset of the mounting base 30.

[0058] In the embodiment, the expansion board 10 is provided with a connecting shaft 11 fixed at the expansion board 10 close to the lower surface, and the mounting seat 30 is provided with a rotating hole and is rotatably sleeved on the connecting shaft 11, and the expansion board 10 does not interfere with the rotation of the mounting seat 30 when rotating. The mounting seat 30 is in and out of the accommodating cavity 20 through the rotating method through the connecting shaft 11. The expansion board 10 can be provided with a limiting structure on one side of the connecting shaft 11 to limit the rotation angle of the mounting seat 30. The connecting shaft 11 is also sleeved with a second elastic member 12, which acts on the mounting seat 30 and is used to provide the mounting seat 30 with an elastic force for returning to rotation. For example, the second elastic member 12 can be a torsion spring, the main body of the torsion spring is sleeved on the connecting shaft 11, and the torsion arms of the torsion spring are connected with the mounting seat 30 and the expansion board 10 respectively. The rotating opening state of the mounting seat 30 is the initial state, and the mounting seat 30 enters the accommodating cavity 20 to be the locked state. When the user releases the locked cooperation, the mounting seat 30 is automatically withdrawn from the accommodating cavity 20 to the initial state through the second elastic member 12, without the need for the user to manually take out.

[0059] Referring to Figure 5 As shown in the figure, in an embodiment, the mounting seat 30 is provided with a mounting cavity 31 and a sealing cover 32 detachably connected with the mounting cavity 31 and used for closing the mounting cavity 31, and the mounting cavity 31 is used for mounting the tracker 40.

[0060] In the embodiment, the mounting seat 30 is provided with a mounting cavity 31, which is a closed internal space with one side opening, and the mounting cavity 31 is used for mounting the tracker 40. For example, the opening of the mounting cavity 31 is located on the upper surface of the mounting seat 30, and the tracker 40 can be disassembled only when the mounting seat 30 is taken out of the accommodating cavity 20. The mounting cavity 31 is arranged in the central region of the mounting seat 30, and the inner side of the cavity can be provided with a positioning protrusion or a groove to help align the mounting position of the tracker 40, prevent installation errors, and ensure that the tracker 40 can be stably embedded. The detachable connection structure is adopted between the sealing cover 32 and the mounting cavity 31, which can adopt buckle, magnetic attraction or threaded connection and the like. Among them, the buckle connection mode includes: vertical clamping, oblique angle clamping and rotating clamping. For example, the threaded connection mode is adopted between the sealing cover 32 and the mounting cavity 31. Through the effective closing of the sealing cover 32, a relatively closed environment can be formed in the mounting cavity 31, which prevents harmful substances such as dust and water vapor from entering, helps to prolong the service life of the tracker 40, and improves the working stability of the equipment.

[0061] Referring to Figure 5 As shown in the figure, in an embodiment, the mounting cavity 31 is provided with an elastic buffer 33, which is used for contacting and elastically buffering the tracker 40.

[0062] In the embodiment, the elastic buffer 33 is arranged in the installation cavity 31 to ensure the stability of the tracker 40 after installation. The elastic buffer 33 can be uniformly arranged along the inner wall of the installation cavity 31, or be arranged as several independent buffer pads according to the contact surface of the tracker 40. The elastic buffer 33 is made of high-elastic and wear-resistant material, such as silica gel, EVA foam or TPU, and has good buffering performance and environmental resistance. The shape of the elastic buffer 33 matches the profile of the outer shell of the tracker 40. The elastic buffer 33 forms a buffer layer between the tracker 40 and the installation cavity 31, absorbs external mechanical vibration and impact, effectively prevents the tracker 40 from being displaced or damaged due to vibration, and improves the stability of the equipment in a dynamic environment. Meanwhile, the close contact between the elastic buffer 33 and the surface of the tracker 40 not only increases the friction between the tracker 40 and the installation cavity 31, but also automatically adjusts the small gap between the tracker 40 and the installation cavity 31 to some extent, so that the installation effect is more stable and reliable.

[0063] Referring to Figure 3 and Figure 4 In an embodiment, the outer surface of the mounting seat 30 is provided with a first opening 34 communicating with the installation cavity 31.

[0064] In the embodiment, the first opening 34 is reserved on the outer surface of the mounting seat 30, and the first opening 34 communicates with the internal installation cavity 31. The number and shape of the first opening 34 can be designed according to actual needs. For example, the first opening 34 is located on the side of the mounting seat 30. The first opening 34 serves as a communication passage between the internal installation cavity 31 and the outside, which helps the air in the installation cavity 31 to communicate, improves the heat accumulation caused by the long-time work of the tracker 40, and improves the heat dissipation performance of the equipment and keeps the tracker 40 running at a suitable working temperature. Meanwhile, the signal of the tracker 40 can be transmitted outward through the first opening 34, and in addition, the user can also observe whether the tracker 40 is placed in the installation cavity 31 through the first opening 34.

[0065] Referring to Figure 3 and Figure 4 In an embodiment, the expansion board 10 is provided with a second opening 35 communicating with the accommodating cavity 20 and opposite to the first opening 34.

[0066] In the embodiment, the second opening 35 is reserved on the outer surface of the expansion board 10, and the second opening 35 communicates with the internal accommodating cavity 20 and is opposite to the first opening 34. The signal of the tracker 40 can be transmitted outward through the second opening 35, and in addition, the user can also observe whether the tracker 40 is placed in the installation cavity 31 through the second opening 35 and the first opening 34.

[0067] Referring to Figure 6 and Figure 7As shown, in an embodiment, the photographic and video equipment has a battery compartment for mounting a battery and a compartment cover that can close or open the battery compartment, and the accommodating cavity 20 is positioned corresponding to the position of the compartment cover.

[0068] In the embodiment, the conventional expansion board 10 leaves space in the position of the battery compartment of the photographic and video equipment for battery replacement, and the position of the accommodating cavity 20 is arranged in the corresponding position of the battery compartment of the photographic and video equipment, so that the space of the expansion board 10 is fully utilized, and the installation of the tracker 40 is very concealed.
