[0002] In the field of photography equipment, expansion frames, as important auxiliary devices, are widely used in various photography equipment such as cameras, camcorders, and action cameras to meet users' needs for expanding the functionality of their devices. To ensure the stability of the photography equipment when placed on the ground, and to avoid wear and scratches caused by direct contact between the lens and the surface, traditional expansion frames typically employ a foldable support structure combined with a fully enclosed design. This design distributes the weight of the equipment through the support structure, and the fully enclosed shell isolates the lens from external contact, achieving a significant effect in terms of physical protection.

[0003] However, since photographic equipment (such as smart cameras and action cameras) usually integrates wireless signal transceiver modules such as Wi-Fi and Bluetooth, foldable support components can physically obstruct the wireless signal transceiver modules of the photographic equipment, interfering with the wireless signal transmission function of the photographic equipment. This makes it impossible for the photographic equipment to perform data transmission and remote control functions with other devices, greatly limiting the convenience and functionality of the photographic equipment. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes an extension frame for a photographic device, comprising:

[0006] The frame has an inner space for accommodating the camera device, and one side of the frame has a hollow opening corresponding to the position of the signal transceiver terminal of the camera device.

[0007] The support member is provided with an avoidance opening. The support member is movably connected to one side of the frame and can be unfolded or folded relative to the frame. When the support member is folded, the avoidance opening is aligned and closed with the hollow opening.

The first connecting arm and the second connecting arm are spaced apart and opposite to each other, forming a notch. The first connecting arm is provided with a first connecting hole communicating with the notch. The second connecting arm is provided with a second connecting hole communicating with the notch.

[0012] The connecting part is housed within the notch, and the two ends of the rotating shaft are respectively housed within the first connecting hole and the second connecting hole.

[0031] Please refer to Figures 1 to 3 One embodiment of this application proposes an expansion frame 100 for a photographic device, including a frame 10 and a support member 20. The inner side of the frame 10 has a receiving space 11 for accommodating the photographic device. One side of the frame 10 is provided with a hollow opening 12 corresponding to the position of the signal transceiver terminal of the photographic device. The support member 20 is provided with an avoidance opening 21. The support member 20 is movably connected to one side of the frame 10 and can be unfolded or folded relative to the frame 10. When the support member 20 is folded, the avoidance opening 21 is aligned and closed with the hollow opening 12.

[0032] The inner accommodating space 11 of the frame 10 is designed to accommodate different models of photographic equipment. Through precise dimensional design, it tightly encloses the equipment, providing basic physical protection against damage such as collisions and scratches during daily use, transportation, or placement. The perforated opening 12 on one side of the frame 10 precisely corresponds to the signal transceiver position of the photographic equipment. This opening 12 eliminates the shielding effect on wireless signals, ensuring the normal operation of the wireless signal transceiver module and enabling functions such as data transmission and remote control.

[0033] The support component 20 is movably connected to one side of the frame 10, and has both unfolded and folded states. In the unfolded state, the support component 20, through its structural design, distributes the weight of the photographic equipment, stably supporting the equipment on the placement surface and preventing tipping due to an unstable center of gravity. This provides reliable placement stability for the photographic equipment and avoids direct contact between the lens and the placement surface, preventing wear and scratches. In the folded state, the clearance opening 21 of the support component 20 aligns and closes with the hollow opening 12 of the frame 10, maintaining the integrity of the signal transmission channel while reducing the overall volume of the expansion frame 100 for easy storage and carrying. Furthermore, the clearance opening 21 design of the support component 20 minimizes interference with signal transmission even when the equipment is unfolded.

[0034] The expansion frame 100 of this application solves the problem of physical obstruction of wireless signals through the combined design of the hollow opening 12 and the avoidance opening 21. The wireless signal of the photography equipment can efficiently penetrate the frame 10. In terms of data transmission, it can realize fast and stable transmission of files such as photos and videos, reducing transmission interruptions and delays. In terms of remote control function, users can control the photography equipment in real time and accurately through mobile APP and other devices, which greatly improves the intelligent user experience of the photography equipment.

[0035] Please refer to Figure 2 In some embodiments, a connecting part 13 is provided on one side of the frame 10. The connecting part 13 is provided with a shaft hole 131 and a rotating shaft 132 passing through the shaft hole 131. A bushing 133 is provided on the rotating shaft 132 and is located in the shaft hole 131. The support member 20 is connected to both ends of the rotating shaft 132.

[0036] In this embodiment, the connecting part 13 serves as the connecting hub between the support member 20 and the frame 10. Its core function is to provide an installation carrier and movable foundation for the rotating shaft 132 and the support member 20. The precisely set shaft hole 131 ensures the accuracy of the installation position of the rotating shaft 132, thereby guaranteeing that the support member 20 can rotate stably around a fixed axis during unfolding and folding, maintaining the overall structural stability of the expansion frame 100. Simultaneously, the connecting part 13 is integrally formed with the frame 10 or combined using a high-strength connection process, ensuring that the connecting part 13 itself has sufficient strength to withstand the gravity and external forces applied by the photographic equipment when the support member 20 is unfolded.

[0037] The rotating shaft 132 is a key component that enables the rotation of the support member 20. Its two ends are firmly connected to the support member 20, converting the external force applied by the user onto the support member 20 into its own rotational power. The rotation of the rotating shaft 132 within the shaft hole 131 drives the support member 20 to unfold or fold, enabling it to perform its corresponding function in different states. The rotating shaft 132 must possess high strength and rigidity to prevent deformation or breakage during frequent rotation and under the weight of the equipment, ensuring the reliable operation of the support member 20.

[0038] The bushing 133 is fitted around the rotating shaft 132 and located in the shaft hole 131, mainly serving to reduce friction, improve wear resistance, and protect the rotating shaft 132 and the frame 10. During the rotation of the rotating shaft 132, the bushing 133 acts as an intermediate medium, reducing direct contact and friction between the rotating shaft 132 and the inner wall of the shaft hole 131, thus reducing component wear and extending the service life of the rotating shaft 132 and the frame 10. At the same time, the bushing 133 also provides a certain positioning and guiding function for the rotating shaft 132, ensuring that the rotating shaft 132 remains stable during rotation, avoiding wobbling or deviation, and further improving the smoothness and stability of the rotation of the support member 20.

[0039] The combined design of the connecting part 13, the rotating shaft 132, and the bushing 133 enhances the stability of the connection between the support member 20 and the frame 10 compared to traditional simple connection methods. The anti-friction properties of the bushing 133 effectively reduce wear between components, allowing the support member 20 to maintain good rotational performance even after long-term and frequent unfolding and folding operations. This reduces the possibility of functional failure of the expansion frame 100 due to damage to the connection structure, extends the overall service life of the expansion frame 100, and reduces the user's usage and maintenance costs.

[0040] In some embodiments, a storage cavity 14 is provided on one side of the frame 10, and the support member 20 is stored in the storage cavity 14 when folded.

[0041] In this embodiment, the storage cavity 14 provided on one side of the frame 10 has a shape that matches the contour of the folded support member 20, and a depth that matches the folded thickness of the support member 20, ensuring that the support member 20 can be completely embedded within it. After folding, the support member 20 is stored in the storage cavity 14, and the frame 10 forms a protective shell, preventing the support member 20 from colliding or rubbing against external objects during carrying or transportation, reducing the risk of damage to the support member 20, and extending its service life. Moreover, by storing the support member 20 inside the frame 10, the overall volume of the expansion frame 100 is further reduced, achieving a more compact form.

[0042] Please continue to refer to this. Figure 2 In some embodiments, the support member 20 includes a first arm 22, a second arm 23 and a third arm 24 connected in sequence. The first arm 22 and the third arm 24 are parallel and opposite to each other. The end of the first arm 22 facing away from the second arm 23 extends inward to form a first connecting arm 25. The end of the third arm 24 facing away from the second arm 23 extends inward to form a second connecting arm 26. The first connecting arm 25 and the second connecting arm 26 are spaced apart and opposite to each other and form a notch 27. The first connecting arm 25 is provided with a first connecting hole 251 communicating with the notch 27. The second connecting arm 26 is provided with a second connecting hole 261 communicating with the notch 27.

[0043] The connecting part 13 is housed in the notch 27, and the two ends of the rotating shaft 132 are respectively housed in the first connecting hole 251 and the second connecting hole 261.

[0044] In this embodiment, the first arm 22 and the third arm 24 are arranged parallel to each other and opposite to each other, forming the main load-bearing structure of the support member 20. In the unfolded state, they directly bear the weight of the photographic equipment and form stable support through contact with the placement surface; in the folded state, they retract towards the frame 10, reducing the overall volume of the extension frame 100, making it easier to store and carry.

[0045] The second arm 23 serves as the hub connecting the first arm 22 and the third arm 24, playing a crucial role in integrating and transmitting the forces of the two arms while maintaining the rigidity and stability of the overall structure of the support member 20 and preventing twisting and deformation under stress.

[0046] The first connecting arm 25 extends inward from the end of the first support arm 22 facing away from the second support arm 23, and the first connecting hole 251 on it mates with one end of the rotating shaft 132. It is not only the connecting carrier between the support member 20 and the connecting part 13, but also accurately transmits external force to the rotating shaft 132 during the rotation of the support member 20, guiding the rotation trajectory of the first support arm 22 and ensuring the accuracy of rotation.

[0047] The second connecting arm 26 is positioned opposite to the first connecting arm 25, and the second connecting hole 261 engages with the other end of the rotating shaft 132. Together with the first connecting arm 25, it forms the rotation fulcrum of the support member 20. The two work together to ensure that the support member 20 can rotate smoothly around a fixed axis when unfolded and folded, thus guaranteeing the stability and reliability of the movement of the support member 20.

[0048] The notch 27 is formed by the first connecting arm 25 and the second connecting arm 26 at intervals and opposite to each other. It is used to accommodate the connecting part 13 of the frame 10, provide space for the connection between the connecting part 13 and the support member 20, and at the same time, prevent the connecting part 13 from interfering with other parts of the support member 20 during the rotation of the support member 20, so as to ensure the smoothness of the rotation.

[0049] The first connecting hole 251 and the second connecting hole 261 are respectively connected to the notch 27, precisely fitting both ends of the rotating shaft 132. The size of the holes fits tightly with the rotating shaft 132, restricting the axial movement of the rotating shaft 132, making the rotating shaft 132 the fixed axis of rotation of the support member 20, ensuring the positioning accuracy of the support member 20 in different states, thereby ensuring the alignment accuracy of the support member 20 and the hollow opening 12 of the frame 10, and maintaining the integrity of the signal transmission channel.

[0050] The three-section arm structure of this embodiment, together with the parallel first arm 22 and the third arm 24, forms a stable triangular support system. Compared with traditional single-arm or double-arm support, the anti-tipping ability is significantly improved, providing more reliable physical support for the photography equipment. Moreover, when the support member 20 is folded, the precise fit between the notch 27 and the connecting part 13, as well as the positioning of the first connecting hole 251 and the second connecting hole 261 on the rotating shaft 132, allows the clearance opening 21 to be precisely aligned and closed with the hollow opening 12 of the frame 10, forming an unobstructed signal transmission channel. This design effectively avoids signal obstruction caused by the rotation deviation of the support member 20, and even after frequent unfolding and folding operations, it can still ensure the stable transmission of wireless signals of the photography equipment, meeting the user's continuous demand for intelligent functions of the photography equipment.

[0051] In some embodiments, the third arm 24 is provided with a handle position 28, which protrudes outside the storage cavity 14 when the support member 20 is folded.

[0052] The handle 28 on the third arm 24 features a recessed or protruding design. When the support member 20 is folded, the handle 28 protrudes from the storage cavity 14, conforming to ergonomic design and facilitating finger application. Users can easily pull the support member 20 out of the storage cavity 14 and unfold it simply by gripping the handle 28 with their thumb or forefinger. The operation can be completed with one hand without the need for tools, greatly improving efficiency.

[0053] Furthermore, the protruding position of the handle position 28 and the rotation axis 132 of the support member 20 form a reasonable torque arm, which allows the user to more accurately control the rotation angle of the support member 20 when applying force, ensuring a smooth unfolding process and accurate positioning, and avoiding jamming or misalignment of the support member 20 due to uneven force application.

[0054] In some embodiments, the size of the clearance opening 21 is greater than or equal to the size of the cutout opening 12.

[0055] The cutout opening 12 is a signal window reserved in the frame 10 for the signal transceiver of the photography equipment, and its size must cover the physical area of ​​the signal module (such as the location of the Wi-Fi antenna). The clearance opening 21 is a corresponding structure on the support member 20, and its size is designed to be greater than or equal to the size of the cutout opening 12. This ensures that when the support member 20 is folded, even if there are processing errors or assembly deviations, the clearance opening 21 can completely cover the cutout opening 12, avoiding signal blockage caused by misalignment.

[0056] In some embodiments, the frame 10 includes a first border 15, a second border 16, a third border 17, and a fourth border 18 connected end to end. The first border 15 is parallel to and opposite to the third border 17, and the second border 16 is parallel to and opposite to the fourth border 18.

[0057] The support member 20 is connected to at least one of the first frame 15, the second frame 16 and the third frame 17.

[0058] In this embodiment, the first frame 15 and the third frame 17 are arranged parallel to each other and opposite to each other, forming the main load-bearing sides of the frame 10. When the photographic equipment is placed inside the frame 10, the first frame 15 and the third frame 17 jointly bear the weight of the equipment in the length direction, evenly distributing the weight of the equipment throughout the entire frame 10 structure. At the same time, they are also one of the main connection points of the support member 20, and through cooperation with the support member 20, the vertical support stability of the frame 10 is further enhanced.

[0059] The second frame 16 and the fourth frame 18 serve as auxiliary frames perpendicular to the first and third frames 17. Their main function is to constrain and fix the frame 10, preventing deformation under stress. Together with the first and third frames 17, they form a closed quadrilateral structure, ensuring sufficient rigidity in all directions and providing comprehensive physical protection for the photographic equipment.

[0060] The frame 10 adopts a quadrilateral frame structure, which is formed by connecting the first frame 15, the second frame 16, the third frame 17, and the fourth frame 18 end to end, forming a stable rectangular or square accommodating space 11. This structure is based on the principle of quadrilateral stability in mechanics, and provides a stable enclosure frame for the photographic equipment through the mutual support and constraint of the four frames.

[0061] The support member 20 is connected to at least one of the first frame 15, the second frame 16, and the third frame 17. The different connection positions determine the force direction and rotation axis of the support member 20. For example, when the support member 20 is connected to the first frame 15, the unfolded support force mainly acts on the direction of the third frame 17 opposite to the first frame 15, distributing the weight of the photography equipment to different frames through the lever principle to maintain overall balance; while when connected to the second frame 16, it can achieve lateral support to adapt to different placement scenarios.

[0062] In this embodiment, the design of the support member 20, which can be connected to different frames, allows the expansion frame 100 to adapt to diverse usage scenarios. When shooting outdoors, if the device needs to be placed on a slope, the support member 20 can be connected to the second frame 16 to provide lateral support and keep the device level; when shooting on a table, connecting it to the first frame 15 provides conventional vertical support. This flexible support method meets the user's need for device stability in different environments and greatly expands the application range of the expansion frame 100.

[0063] In some embodiments, the support member 20 is connected to the first frame 15 and the third frame 17.

[0064] The support member 20 is connected to both the first frame 15 and the third frame 17, forming a symmetrical support structure with two fulcrums. This design is based on the principle of symmetrical balance and the force distribution mechanism in mechanics. When the photographic equipment is placed inside the extension frame 100, the equipment's weight is transmitted to the support member 20 through the frame 10. Since the two ends of the support member 20 are connected to the first frame 15 and the third frame 17 respectively, the weight is evenly distributed across the two parallel frames, forming a stable closed-loop force distribution. In the unfolded state, the support member 20 vertically transmits the equipment's weight to the placement surface, reducing stress concentration at a single fulcrum. When folded, both ends rotate synchronously to ensure precise alignment between the clearance opening 21 and the hollow opening 12 of the frame 10, maintaining the integrity of the signal transmission channel.

[0065] In this embodiment, the support member 20 serves as a link between the first frame 15 and the third frame 17, undertaking the core function of weight distribution. When the weight of the device is applied to the frame 10, the support member 20 evenly distributes the force to the connection points at both ends, preventing one frame from being subjected to excessive pressure and deforming, thus ensuring the structural stability of the frame 10. Moreover, since both ends are connected simultaneously, the support member 20 maintains synchronous movement during unfolding and folding, avoiding rotational jamming or offset caused by uneven force on one end. This synchronicity ensures that the clearance opening 21 on the support member 20 and the hollow opening 12 of the frame 10 are always precisely aligned, maintaining unobstructed signal transmission channels even after frequent operation.

[0066] In some embodiments, one end of the second frame 16 is movably connected to the first frame 15, and the other end of the second frame 16 is detachably connected to the third frame 17, with the support member 20 connected to the second frame 16.

[0067] The second frame 16 features a design with one end movable and the other detachable, enabling dynamic opening and closing of the frame 10 structure. One end is movably connected to the first frame 15 via a damping pivot 132, allowing for 180° opening and closing rotation; the other end is detachably connected to the third frame 17 using a magnetic snap-on clip or quick-release screw. When the photographic equipment needs to be operated, the detachable connection is released, allowing the second frame 16 to rotate around the damping pivot 132, creating a single-sided open space for easy access to the photographic equipment from the storage space 11.

[0068] The support member 20 is connected to the second frame 16, forming an efficient cooperation with the quick-opening and closing design of the second frame 16. When it is necessary to operate the photography equipment (such as changing the battery or installing the lens), the user only needs to quickly open the second frame 16. The support member 20 will not obstruct the operating space, and after the operation is completed, the second frame 16 can be quickly closed, allowing the support member 20 to return to its original position and continue to play its supporting role.

[0069] In some embodiments, the outer side wall of the frame 10 is provided with a plurality of expansion interfaces 19, the expansion interfaces 19 including at least one of a cold shoe interface and a threaded hole.

[0070] In this embodiment, a variety of expansion interfaces 19, such as a cold shoe interface and threaded holes, are provided on the outer wall of the frame 10, providing rich ways to connect external devices and expand the functions of the photography equipment. The cold shoe interface is quickly connected and fixed to external devices (such as fill lights and microphones) through mechanical clips; the threaded holes adopt standard thread specifications, which are suitable for screw fixing of tripods, gimbals, and other equipment, and achieve a stable connection by utilizing the friction of the thread engagement.

[0071] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
