To meet this demand, various different types of power bank mounting brackets and accessories have emerged on the market.

[0003] In the related art, the bracket for clamping the power bank is usually directly locked on a cage (that is, a camera protection rack or an energy expansion mounting bracket) by screws. This mounting method mainly locks the bracket for clamping the power bank directly on the side of the cage and other positions by screws to meet the user's demand for stable installation of the power bank.

[0004] Although the mounting method in the related art can effectively fix the power bank, it has several obvious defects.

[0051] Referring to Figure 1 and Figure 2 , Figure 1 FIG. Figure 2 is a schematic structural view of a photographic auxiliary support assembly in an embodiment of the present utility model,

[0052] An embodiment of the present utility model provides a photographic auxiliary support assembly, which includes:

[0053] A main support 100, the main support 100 includes a first arm 110 and a second arm 120. One end of the second arm 120 is rotatably connected to one end of the first arm 110, and the first arm 110 is used to provide an installation place for a photographic device;

[0054] An extension support 200, the extension support 200 is detachably connected to the second arm 120, and the extension support 200 is used for detachably installing a mobile power supply.

[0055] In this embodiment, the photographic auxiliary support assembly is mainly applied to the field of photography, such as long-time photography and scenarios requiring multi-device expansion. Specifically, the photographic auxiliary support assembly is designed to be installed on a cage (a protection frame for a photographic device) to provide more installation positions. The assembly includes a main support 100 and an extension support 200. The main support 100 includes a first arm 110 and a second arm 120, wherein one end of the second arm 120 is rotatably connected to one end of the first arm 110, and the first arm 110 is used to provide an installation place for a photographic device.

[0056] Among them, the rotatable connection manner between the first arm 110 and the second arm 120 can be a rotating shaft, a hinge or a spherical joint, etc. Exemplarily, the rotating shaft connection manner can be to connect the first arm 110 and the second arm 120 together through an axis, allowing the two to rotate around the axis. This structure is simple and stable and can provide precise angle adjustment. The rotating shaft generally includes a shaft fixed on the first arm 110 and a hole sleeved on the second arm 120, and the two are fixed by a shaft pin or a bolt.

[0057] For another example, the hinge connection method is similar to a common door hinge, and connects the first arm 110 and the second arm 120 through two meshing metal sheets. This connection method allows the arms to rotate in a plane and is usually used in application scenarios that require frequent angle adjustment.

[0058] To meet the requirements of some complex shooting angles, a spherical joint can be adopted. The spherical joint connection method uses a spherical joint to connect the first arm 110 and the second arm 120. The spherical joint can be fixed on the first arm 110, and the ball socket is fixed on the second arm 120. The spherical joint provides the greatest degree of freedom, enabling the arms to be adjusted at multiple angles in three-dimensional space.

[0059] During the photography process, it is inevitable to move the photographic device. Therefore, to ensure its light weight and durability, the material of the photographic auxiliary support assembly can be aluminum alloy or carbon fiber to ensure its light weight and durability.

[0060] In this embodiment, the extension bracket 200 is detachably connected to the second arm 120 and is used for detachably installing devices such as a mobile power supply. The reason for detachably installing the extension bracket 200 on the second arm is to facilitate the user to replace the extension bracket 200 with a corresponding function according to specific needs. For example, the extension bracket 200 can be a clamping bracket 210 for clamping a mobile power supply, an NP-F battery base 220, or a signal transmission device (commonly known as a video transmitter), etc. As for the material of the extension bracket 200, aluminum alloy or carbon fiber can also be used.

[0061] Among them, image transmission refers to an image transmission device, which is mainly used to transmit the real-time images captured by a camera to a display screen for the director or photographer to monitor the shooting effect in real time. The image transmission device sends the video signal to a remote display device wirelessly or by wire, providing instant image feedback at the shooting scene. The image transmission device usually consists of a transmitter and a receiver. The transmitter is installed on the camera and wirelessly transmits the captured video signal to the receiver, which is connected to a display screen or monitor to display the real-time image. The image transmission device is very important in scenarios where real-time monitoring and adjustment of the shooting angle are required, ensuring the accuracy and efficiency of shooting. The NP-F battery base 220 is a bracket or base for installing and connecting NP-F series batteries. The NP-F battery is a rechargeable battery widely used in photographic equipment (similar to a mobile power bank), featuring high capacity and long battery life. The NP-F battery base 220 can firmly hold the battery and provide a stable power supply for the photographic equipment through the power interface on the base. The battery base usually has a safety locking mechanism to ensure that the battery does not loosen or fall off during shooting. By using the NP-F battery base 220, users can conveniently replace the battery to ensure that the device does not interrupt operation due to insufficient power during long-term shooting.

[0062] During use, taking the clamping bracket 210 of the expansion bracket 200 for clamping the mobile power bank as an example, during a long-term photography or shooting process, the photographic device needs continuous power supply. At this time, the mobile power bank can be installed on the clamping bracket 210 of the expansion bracket 200. If it is necessary to adjust the position of the mobile power bank to avoid blocking the lens or changing the center of gravity, the user only needs to apply an external force to push the second arm 120 to rotate, thereby driving the expansion bracket 200 and the mobile power bank to swing to a suitable position together, so as to avoid the position of the mobile power bank from interfering with the user's operation of the photographic device. There is no need to disassemble and reinstall, and the operation is very convenient.

[0063] For another example, when using the image transmission device, the cameraman can install the photographic auxiliary bracket assembly on the camera cage and flexibly adjust the position of the bracket through the rotatable connection of the first arm 110 and the second arm 120 of the main bracket 100. The expansion bracket 200 is installed at the end of the second arm 120, and the transmitter is installed on the expansion bracket 200.

[0064] After shooting starts, the image transmission device transmits the real-time captured images to the monitor in the director's hand via wireless signals. In some scenarios, due to the complex on-site environment, it may be necessary to frequently adjust the position and angle of the camera during shooting to capture the best pictures. As the position of the transmitter of the image transmission device also changes accordingly, the position of the transmitter may affect the signal transmission quality or block the camera's field of view.

[0065] At this time, the cameraman can apply an external force to make the second arm 120 rotate around the connection point of the first arm 110, thereby driving the extension bracket 200 and the transmitter of the video transmission device to swing to a preset position for position adjustment. For example, the cameraman swings the second arm 120 to the left to avoid the field of view of the camera and at the same time adjusts to the position with the best signal transmission effect. This adjustment process does not require disassembling any components and can be completed with simple manual operations, greatly improving the convenience and efficiency of the operation.

[0066] In the technical solution of this embodiment, by rotatably connecting the first arm 110 and the second arm 120 of the main bracket 100, the second arm 120 can rotate relative to the first arm 110 under the action of an external force to drive the mobile power supply to move for position adjustment. Then, by detachably connecting the extension bracket 200 to the second arm 120, the user can detach the extension bracket 200 for installing the mobile power supply and replace it with an extension bracket with other functions (for example, replacing it with an NP-F battery base); during the actual shooting process, to prevent the position of the mobile power supply from interfering with the user's operation of the photographic device, the user can apply an external force to push the second arm 120 to rotate, which can drive the extension bracket 200 and the mobile power supply to swing to a suitable position together. The adjustment process does not require disassembling and reinstalling the extension bracket 200, and the operation is very convenient.

[0067] Continue to refer to Figure 1 and Figure 2 , in this embodiment, the extension bracket 200 includes a clamping bracket 210 for clamping the mobile power supply, and the clamping bracket 210 is detachably and rotatably connected to the second arm 120.

[0068] In this embodiment, the extension bracket 200 includes a clamping bracket 210 for clamping the mobile power supply. Among them, the clamping bracket 210 can clamp the mobile power supply in various ways. For example, through a screw clamp or a quick-release locking mechanism, etc. These methods can ensure that the mobile power supply is firmly fixed on the clamping bracket 210 in different usage environments.

[0069] Exemplarily, the screw clamp can achieve clamping by means of screw rotation. Structurally, the screw clamp includes a screw rod and two clamping arms. The user rotates the screw rod to gradually bring the clamping arms closer together, thereby clamping the mobile power supply. The screw clamp can provide a large clamping force and can precisely adjust the clamping force.

[0070] The quick release locking mechanism uses a locking device and a release device to achieve quick clamping and release. Structurally, the quick release locking mechanism includes a locking rod and a release button. When the locking rod is pushed to the locking position, the mobile power supply is fixed; when the release button is pressed, the locking rod returns to the initial position and releases the mobile power supply. This mechanism is easy to operate and is suitable for scenarios where the mobile power supply needs to be frequently disassembled and assembled.

[0071] The detachable design of the clamping frame 210 in this embodiment can be realized by means of buckles, bolts or magnetic connections, so that the user can easily remove the clamping frame 210 from the second arm 120. The rotatable connection method includes using a rotating shaft, a spherical joint, etc. These structures can allow the clamping frame 210 to be flexibly adjusted in angle after being installed on the second arm 120.

[0072] In actual use, when the user needs to replace other expansion brackets 200 (for example, replace with NP-F battery base 220), the clamping frame 210 can be easily removed from the second arm 120, which is easy to operate. For another example, during a long shooting process, if a mobile power supply needs to be replaced, the clamping frame 210 can be quickly removed by simply unlocking the buckle or rotating the bolt, and then reinstalled on the second arm 120 after replacing a new mobile power supply.

[0073] At the same time, the rotatable design of the clamping frame 210 allows the user to adjust the angle and position of the mobile power supply as needed during the shooting process. In conjunction with the swing function of the second arm 120, the user can apply external force to make the clamping frame 210 and the mobile power supply rotate and swing together. For example, when the position of the mobile power supply needs to avoid the flip screen of the camera or other equipment, the user can easily adjust the position of the second arm 120 and the clamping frame 210 to ensure the best shooting effect and equipment layout.

[0074] The clamping frame 210 of the present embodiment is detachable and rotatable to cooperate with the swing function of the second arm 120. The user can easily disassemble the clamping frame 210 to replace other expansion brackets 200 (for example, replace it with an NP-F battery base 220) or replace a mobile power supply. The quick disassembly and adjustment functions ensure the stable operation of the device during the shooting process and avoid shooting interruptions due to power problems; the rotatable clamping frame 210 and the swingable second arm 120 enable the user to flexibly adjust the position and angle of the mobile power supply to meet the needs of different shooting scenes.

[0075] See also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the exploded structure of a photography auxiliary bracket assembly in one embodiment of the utility model. Figure 3 The figure is a schematic diagram of the exploded structure of the photography auxiliary bracket assembly in one embodiment of the utility model.

[0076] In this embodiment, the clamping bracket 210 includes:

[0077] A first clamping arm 211, one side of the first clamping arm 211 is rotatably connected to the other end of the second support arm 120;

[0078] A second clamping arm 212, the second clamping arm 212 is movably installed at one end of the first clamping arm 211, and the second clamping arm 212 can reciprocate in the first direction to loosen or clamp the mobile power supply.

[0079] In this embodiment, the clamping bracket 210 is composed of a first clamping arm 211 and a second clamping arm 212. Specifically, one side of a clamping arm is rotatably connected to the other end of the second support arm 120, allowing the clamping bracket 210 to be adjusted at different angles. The second clamping arm 212 is movably installed at one end of the first clamping arm 211 and can reciprocate in the first direction (usually the horizontal direction) to loosen or clamp the mobile power supply. Among them, there are various ways to achieve pressing between the first clamping arm 211 and the second clamping arm 212. Among them, a tension spring can be installed between the first clamping arm 211 and the second clamping arm 212, and the elastic force generated by the tension spring clamps the two clamping arms together. When the user applies an external force to pull open the clamping arms, the mobile power supply can be placed in or taken out; after releasing the external force, the tension spring will automatically clamp the clamping arms to fix the mobile power supply.

[0080] In some embodiments, the first clamping arm 211 and the second clamping arm 212 can also be connected by bolts. Rotating the bolts can adjust the distance between the clamping arms to achieve the purpose of clamping or loosening the mobile power supply. The user can precisely control the clamping force by rotating the bolts to ensure that the mobile power supply is firm and does not loosen.

[0081] In some embodiments, soft pads are provided on the inner walls of the first clamping arm 211 and the second clamping arm 212. The material of the soft pads can be rubber, silica gel or other soft and durable materials; the reason for setting the soft pads is that the soft pads can effectively prevent the surface of the mobile power supply from being scratched or damaged during the clamping process and protect the appearance of the mobile power supply. Most importantly, the surface of the soft pads has a high coefficient of friction, which can increase the clamping force and prevent the mobile power supply from sliding or loosening during use. In this way, the clamping bracket 210 in this embodiment can flexibly adjust and firmly fix the mobile power supply, while providing effective protection and anti-slip functions to ensure the stability and safety of the mobile power supply in various use scenarios.

[0082] Continue to refer to Figure 2 , in this embodiment, the clamping bracket 210 further includes a first locking member 212b and an elastic member 212c;

[0083] One end of the first clamping arm 211 is configured with a first guiding post 211a and a second guiding post 211b arranged in parallel;

[0084] One end of the second clamping arm 212 facing the first clamping arm 211 is provided with a guiding groove 212a for the first guiding post 211a and the second guiding post 211b to extend into;

[0085] Among them, an elastic member 212c is installed in the first guiding post 211a. One end of the elastic member 212c abuts against the bottom of the guiding groove 212a for elastically supporting the second clamping arm 212. A first locking member 212b extends into the guiding groove 212a from the other end of the second clamping arm 212 and is threadedly connected to the second guiding post 211b.

[0086] In this embodiment, the first locking member 212b is used to lock the second clamping arm 212 to prevent it from loosening when clamping the mobile power supply. In this embodiment, the first locking member 212b can be a screw rod. Specifically, the screw rod is locked by rotation. One end of the screw rod is fixed to the second clamping arm 212, and the other end passes through the guiding groove 212a and is threadedly connected to the second guiding post 211b. The user can tighten the screw rod to the second guiding post 211b by rotating it to lock and fix the second clamping arm 212.

[0087] The elastic member 212c in this embodiment is used to provide elastic support so that the second clamping arm 212 can automatically expand when the locked state is released, facilitating the user to pick up and place the mobile power supply. In this embodiment, the elastic member 212c can be a tension spring. Specifically, the tension spring is installed in the first guiding post 211a, with one end fixed to the bottom of the guiding groove 212a and the other end connected to the second clamping arm 212. When the pulling of the second clamping arm 212 is released, the elastic force of the tension spring will automatically pull the second clamping arm 212 back to approach the second clamping arm 212, thereby clamping the mobile power supply.

[0088] Of course, in some embodiments, a spring can also be used. Specifically, the spring is also a common form of the elastic member 212c and can be installed inside or outside the first guiding post 211a or the second guiding post 211b. One end is fixed to the bottom of the guiding groove 212a, and the other end abuts against the second clamping arm 212. When the locking is released, the elastic force of the spring will automatically expand the clamping arm, facilitating the user's operation.

[0089] In actual use, when the user needs to take or place the mobile power supply, the cooperation between the first guide column 211a and the second guide column 211b and the guide groove 212a can ensure the stability and alignment of the two clamping frames 210, and prevent the clamping arms from being misaligned. In addition, the elastic member 212c is installed in the first guide column 211a, and one end of the elastic member 212c abuts against the bottom of the guide groove 212a, providing elastic support so that the second clamping arm 212 can move smoothly along the guide column.

[0090] In the locking operation scenario, the user applies an external force to the two clamping arms to bring them together. At this time, the first locking member 212b can be rotated to extend it from the other end of the second clamping arm 212 into the guide groove 212a and threadedly connected with the second guide column 211b, thereby locking and fixing the mobile power supply. When the user needs to release the locking state, he only needs to rotate the first locking member 212b to disengage it from the second guide column 211b, and the elastic force of the elastic member 212c will automatically open the two clamping arms, making it convenient for the user to take out the mobile power supply.

[0091] In this embodiment, the cooperation between the first guide column 211a and the second guide column 211b and the guide groove 212a provides a stable guide in the scene of taking and placing the mobile power supply, ensuring the smoothness and accuracy of the clamping process. The introduction of the first locking member 212b makes the user more convenient and quick in the locking operation, improving the user experience. When the user releases the locking effect of the first locking member 212b, the elastic member 212c can automatically open the two clamping arms, greatly facilitating the user's operation of taking and placing the mobile power supply.

[0092] Continue reading Figure 1 In this embodiment, the first arm 110 has a first side portion 110a and a second side portion 110b that are arranged opposite to each other. The first side portion 110a is used for detachably connecting a photographic device, and the second side portion 110b is used for detachably connecting a support frame or a gimbal quick-release plate.

[0093] In this embodiment, the first side portion 110a is mainly used for detachably connecting the photographic device. Specifically, the first side portion 110a can be designed with a dovetail groove. The dovetail groove can be directly connected to the rabbit cage to ensure a stable connection. In addition, the dovetail groove can also be compatible with other accessories, such as the arc-shaped small board of the stabilizer, so that the user can flexibly switch between different devices, providing greater applicability and convenience.

[0094] Among them, the Arca-Swiss Plate is a standardized quick-release plate system, which was first designed and promoted by Arca-Swiss, a Swiss photographic equipment manufacturer. This system is widely used in the support and fixation of photographic and video equipment. Due to its versatility and stability, the Arca-Swiss Plate has become an industry standard and is adopted by many photographic equipment manufacturers.

[0095] The Arca small plate is usually a rectangular metal plate with a standard dovetail groove design. The structure of the dovetail groove enables the Arca small plate to slide firmly into and lock in a compatible quick-release clamp.

[0096] For the second side portion 110b of this embodiment, it can be designed as an Arca quick-release small plate, which is suitable for quick installation and disassembly. With this design, the second side portion 110b can be conveniently connected to a support frame (the support frame can be a common tripod, monopod or other types of photographic support frames) or a pan-tilt head, achieving stable support and quick installation operations.

[0097] In this embodiment, the dovetail groove design of the first side portion 110a can not only be directly docked with the cage, but also be compatible with other accessories, such as the Arca standard small plate, enabling users to flexibly switch between different devices to meet various shooting needs. The Arca quick-release small plate design of the second side portion 110b enables quick connection and disassembly. Users can conveniently install the support frame or pan-tilt head onto the photographic device, greatly simplifying the operation steps and improving the shooting efficiency.

[0098] Refer to Figures 3 to 5 , Figure 3 which is an exploded structural schematic diagram of a photographic auxiliary support assembly in an embodiment of the present utility model, Figure 4 which is a side view of a photographic auxiliary support assembly in an embodiment of the present utility model, Figure 5 is Figure 4 the sectional view at A-A in

[0099] In this embodiment, the first arm 110 includes:

[0100] A first rotating member 111 is provided at one end of the first arm 110 or one end of the second arm 120. One of the first arm 110 and the second arm 120 is connected to the rotating end of the first rotating member 111. The first rotating member 111 is configured to rotate a preset angle under an external force.

[0101] In this embodiment, the first arm 110 includes a first rotating member 111. The first rotating member 111 is provided at one end of the first arm 110 or one end of the second arm 120. One of the first arm 110 and the second arm 120 is connected to the rotating end of the first rotating member 111. The first rotating member 111 can adopt various forms, such as a rotating shaft, a hinge, or a spherical joint. These rotating members can rotate to a preset angle under an external force and remain at that angle.

[0102] Specifically, the rotating shaft consists of a fixed shaft and a rotatable arm and can achieve 360-degree rotation. Friction pads or gear structures can be configured inside it to ensure stable retention after rotating to a preset angle.

[0103] For the hinge, it allows the first arm 110 and the second arm 120 to rotate in a plane. The hinge can be maintained at a preset angle by setting a limiter or a spring device.

[0104] The spherical joint can provide multi-directional rotational freedom. Through the internal friction pads or locking devices, it can be fixed in place after reaching the preset angle. The damping component provides resistance through internal damping materials (such as silicone or hydraulic oil), making the rotation process smoother and enabling stable retention at the preset angle.

[0105] During actual use, the user can adjust the angle of the second arm 120 by applying an external force. For example, during shooting, the position of the power bank needs to be adjusted to avoid blocking the camera lens or changing the center of gravity of the device. Through the first rotating member 111, the user can easily rotate the arm to quickly adjust the power bank to the required preset position.

[0106] Suppose during shooting, the user finds that the power bank blocks the flip screen of the camera or affects the stability of the camera due to the center of gravity problem. The user only needs to apply an external force to push the second arm 120. At this time, the rotating shaft of the first rotating member 111 rotates, and the second arm 120 will also be adjusted to a new angle accordingly. Due to the internal friction pads or locking devices of the rotating member, the second arm 120 can be stably retained after reaching the preset angle, avoiding affecting the device stability due to loosening or accidental rotation. If a damping component is used, the adjustment process will be smoother and can effectively absorb vibrations, further improving the stability of the device. In this way, the user can adjust the angle of the second arm 120 by applying an external force without complex tools and operations, improving the adjustment efficiency and convenience of the device.

[0107] Continue to refer to Figures 3 to 5 In this embodiment, one end of the first arm 110 is constructed with a mounting post 110c;

[0108] The first rotating member 111 includes:

[0109] A first rotating shaft 111a, one end of the first rotating shaft 111a is fixedly connected to one end of the mounting post 110c;

[0110] A first rotating part 111b, rotatably sleeved on the first rotating shaft 111a. The first rotating part 111b is used to connect to one end of the support arm, and the first rotating part 111b can rotate a preset angle under the action of an external force;

[0111] The first damping component 111c is provided at one end of the first rotating shaft 111a away from the swing arm 121. The first damping component 111c is used to apply rotational damping when the first rotating member 111b rotates relative to the first rotating shaft 111a under an external force, so that the first rotating member 111b remains at a preset angle.

[0112] In this embodiment, only one end of the first support arm 110 is constructed with the mounting post 110c as an example. In other embodiments, a hole can be directly drilled on the first support arm 110 for mounting the first rotating member 111b. Specifically, a through hole 220c is constructed through the side wall of the first support arm 110 for mounting the first rotating member 111b.

[0113] The first rotating member 111 in this embodiment includes: a first rotating shaft 111a and a first rotating part. One end of the first rotating shaft 111a is fixedly connected to one end of the mounting post 110c, providing a stable rotation fulcrum. The first rotating member 111b is rotatably sleeved on the first rotating shaft 111a and is used to connect to one end of the support arm. The first rotating member 111b can be rotated to a preset angle under an external force.

[0114] The first damping component 111c is then provided at one end of the first rotating shaft 111a away from the support arm, and is used to apply rotational damping when the first rotating member 111b rotates relative to the first rotating shaft 111a, so that the first rotating member 111b remains at the preset angle.

[0115] Specifically, a plurality of grooves are provided on the first rotating member 111b and are circumferentially distributed, and a plurality of protrusions are provided on the surface of the first damping component 111c facing the first rotating member 111b. The first damping component 111c includes an elastic member 212c. When the first rotating member 111b rotates under an external force, the contact between the groove and the protrusion causes the elastic member 212c to be compressed, generating a damping force. When the first rotating member 111b rotates to the preset position, the protrusion falls back into the groove under the action of the elastic member 212c. The compression and release process of the elastic member 212c provides a smooth damping effect for the rotation of the first rotating member 111b, enabling it to remain stable after reaching the preset angle.

[0116] Furthermore, the grooves on the first rotating member 111b and the protrusions on the first damping assembly 111c are distributed along the circumferential angle. Specifically, the grooves and protrusions can be evenly arranged on the circumferences of the first rotating member 111b and the first damping assembly 111c. For example, the grooves and protrusions are arranged at an interval of every 10 degrees. Therefore, on the entire 360-degree circumference, there are a total of 36 grooves and 36 corresponding protrusions. This setting with an interval of every 10 degrees enables the first rotating member 111b to stably stay at a new preset angular position every time it rotates 10 degrees under an external force. In this way, the user can accurately adjust and stabilize the position of the device at multiple preset angles between 0 degrees and 360 degrees to meet various usage requirements.

[0117] This design of distribution along the circumferential angle enables the grooves and protrusions to accurately align and generate damping force whenever the first rotating member 111b rotates under an external force, regardless of the angle it rotates to.

[0118] Refer to Figure 3 , in this embodiment, the second arm 120 includes a swing arm 121 and a second rotating member 122. One end of the swing arm 121 is rotatably connected to one end of the first arm 110, and the second rotating member 122 is installed at the other end of the swing arm 121 or the extension bracket 200. One of the swing arm 121 and the extension bracket 200 is connected to the rotating end of the second rotating member 122, and the second rotating member 122 rotates a preset angle under an external force.

[0119] In this embodiment, the swing arm 121 is mainly a component for connecting the first arm 110 and the extension bracket 200, and it needs to have sufficient supporting force. To provide sufficient supporting force, starting from its material, specifically, aluminum alloy can be used. Aluminum alloy has the characteristics of light weight and high strength, which can provide sufficient supporting force while reducing the overall weight. The corrosion resistance of aluminum alloy makes it suitable for various environmental conditions and increases the durability of the device.

[0120] If further weight reduction is required, carbon fiber can be used. Carbon fiber material is not only extremely light but also has very high strength and rigidity. Its excellent seismic resistance can effectively reduce the blurring caused by vibration during shooting, and at the same time, the durability of carbon fiber also enables the device to work stably for a long time.

[0121] During actual use, the second arm 120 provides the user with the ability to flexibly adjust the position and angle of the device through its designed mobility. For example, during shooting, if it is necessary to adjust the position of the mobile power supply to avoid blocking the camera lens or changing the center of gravity of the device, the user can apply an external force to push the swing arm 121 to rotate it around the first arm 110.

[0122] Suppose that during the shooting process, the user finds that the mobile power supply affects the balance of the camera. At this time, the user can apply an external force to rotate the swing arm 121 around the first arm 110 to move the mobile power supply to a new position. At this time, under the action of the second rotating member 122, the user can further finely adjust the expansion bracket 200 so that the mobile power supply is stably maintained at a new preset angle.

[0123] Further, referring to Figures 6 to 8 , Figure 6 is the front view of the photographic auxiliary bracket assembly in an embodiment of the present invention, Figure 7 is Figure 6 the sectional view taken along line B-B in Figure 8 is Figure 7 the enlarged view at C in

[0124] In this embodiment, the second rotating member 122 includes:

[0125] A second rotating shaft 122a, one end of the second rotating shaft 122a is fixedly connected to the swing arm 121, and a gasket 122d is fixedly sleeved at one end of the second rotating shaft 122a close to the swing arm 121;

[0126] A second rotating member 122c, rotatably sleeved on the second rotating shaft 122a and located on the side of the gasket 122d facing away from the swing arm 121. The second rotating member 122c is used to connect to the expansion bracket 200, and the second rotating member 122c can rotate relative to the second rotating shaft 122a under the action of an external force;

[0127] A second damping assembly 122b, disposed at one end of the second rotating shaft 122a away from the swing arm 121. The second damping assembly 122b is used to apply a rotational damping when the second rotating member 122c rotates relative to the second rotating shaft 122a under the action of an external force, so that the second rotating member 122c is maintained at a preset angle.

[0128] In this embodiment, one end of the second rotating shaft 122a is fixedly connected to the swing arm 121 to ensure the structural stability. A gasket 122d is fixedly sleeved at one end close to the swing arm 121 to provide additional support and cushioning. The second rotating member 122c is rotatably sleeved on the second rotating shaft 122a and located on the side of the gasket 122d facing away from the swing arm 121. The second rotating member 122c is used to connect to the expansion bracket 200 and can rotate relative to the second rotating shaft 122a under the action of an external force, allowing flexible angle adjustment. The second damping assembly 122b is disposed at one end of the second rotating shaft 122a away from the swing arm 121. Its function is to apply a rotational damping when the second rotating member 122c rotates relative to the second rotating shaft 122a, so that the second rotating member 122c can be maintained at a preset angle. The damping assembly may include an elastic member 212c or other damping materials to provide a smooth rotational effect and a stable angle maintaining ability.

[0129] During actual use, the user can adjust the angle of the second rotating member 122c by applying an external force. For example, when it is necessary to adjust the position of the mobile power supply on the expansion bracket 200 to avoid blocking the camera lens or changing the center of gravity of the device, the user can push the swing arm 121. Due to the presence of the second damping component 122b, the rotation process will become smooth, and after reaching the required angle, the second rotating member 122c can be stably held and will not move due to loosening.

[0130] In this embodiment, the second rotating member 122c allows the user to easily adjust the position and angle of the device under the action of an external force. After reaching the preset angle, the damping force provided by the second damping component 122b can keep the second rotating member 122c stably in the required position, avoiding affecting the use effect due to accidental loosening.

[0131] Continue to refer to Figure 5 and Figure 6 In this subsequent embodiment, the photographic auxiliary bracket assembly further includes a second locking member 300. The second locking member 300 is provided at the other end of the mounting post 110c and is used to release the first arm 110 and the second arm 120 when adjusting the position of the mobile power supply, allowing the first arm 110 to rotate relative to the second arm 120 under the action of an external force; and locking the first arm 110 and the second arm 120 when fixing the position of the mobile power supply to prevent the first arm 110 from rotating relative to the second arm 120 under the action of an external force.

[0132] In this embodiment, the photographic auxiliary bracket assembly further includes a second locking member 300. The second locking member 300 is provided at the other end of the mounting post 110c. When adjusting the position of the mobile power supply, the second locking member 300 releases the lock between the first arm 110 and the second arm 120, enabling the first arm 110 to rotate freely relative to the second arm 120 under the action of an external force. When fixing the position of the mobile power supply, the second locking member 300 locks the first arm 110 and the second arm 120, preventing the first arm 110 from rotating relative to the second arm 120 under the action of an external force.

[0133] Among them, the second locking member 300 can adopt various forms, including but not limited to screw locking members, spring locks, etc.; taking the screw locking member as an example, the user can adjust its tightness. When the position needs to be adjusted, rotate the screw locking member to release the arm; when the position needs to be fixed, tighten the screw locking member to lock the arm. Of course, it is also possible to release the lock by compressing the spring and restore the locked state of the spring to provide a fast and stable locking method.

[0134] In actual use, suppose the photographer needs to adjust the position of the mobile power supply to avoid blocking the camera lens or changing the center of gravity of the device. First, the photographer rotates or pulls up the second locking member 300 to put it into the release mode. At this time, the first arm 110 can rotate freely relative to the second arm 120 under the action of external force. After the photographer adjusts the positions of the first arm 110 and the second arm 120 to find the best position of the mobile power supply, he tightens or presses down the second locking member 300 to put it into the locking mode, thereby fixing the positions of the first arm 110 and the second arm 120.

[0135] See also Figure 9 , Figure 9 Schematic diagram of the structure of the photography auxiliary bracket assembly in another embodiment of the utility model. In this embodiment, the expansion bracket 200 includes an NP-F battery base 220, which is detachably mounted on the second arm 120 and is used to install an NP-F battery.

[0136] In this embodiment, the NP-F battery base 220 is designed to accommodate and fix the NP-F battery to ensure that the battery is stable and immobile during use. The NP-F battery base 220 can be installed on the second arm 120 by means of buckles, screws, etc., and the user can quickly install or remove the battery base.

[0137] When the user needs to provide continuous power to the photographic device, the NP-F battery can be installed on the NP-F battery base 220, and then the battery base can be fixed on the second arm 120. For example, during a long shooting process, the user finds that the battery is low. At this time, through the quick release mechanism, the user can quickly remove the NP-F battery, replace it with a spare battery, and install it on the NP-F battery base 220 to ensure uninterrupted shooting.

[0138] Further, see Figure 9 In this embodiment, the other end of the second arm 120 is configured with a threaded hole 120a;

[0139] The NP-F battery base 220 has a mounting surface 220a that abuts against the second arm 120, and a bearing surface 220b for bearing the NP-F battery. A through hole 220c is constructed from the bearing surface 220b toward the mounting surface 220a. The through hole 220c is used for a bolt to pass through and be threadedly connected with the threaded hole 120a, so that the mounting component is relatively fixed to the second arm 120.

[0140] In this embodiment, the user can first install the NP-F battery base 220 onto the second arm 120, and then align the mounting surface 220a of the NP-F battery base 220 with the threaded hole 120a of the second arm 120. By passing a bolt through the through hole 220c and screwing it into the threaded hole 120a, the battery base is firmly fixed to the second arm 120. Once the NP-F battery base 220 is fixed, the user can install the NP-F battery onto the bearing surface 220b of the battery base. During use, the NP-F battery can be removed and replaced from the battery base at any time without having to disassemble the battery base.

[0141] In addition, since the second arm 120 is designed as a swingable structure, after the NP-F battery base 220 is installed, the user can flexibly adjust the position of the NP-F battery by adjusting the swing angle of the second arm 120. This can ensure that during shooting, the NP-F battery does not block the camera lens or affect the center of gravity of the device.

[0142] For example, during shooting, when the battery runs out of power, the user only needs to remove the depleted NP-F battery from the battery base and install a new one, without having to disassemble and reinstall the battery base. At the same time, by adjusting the swing angle of the second arm 120, it is possible to ensure that the battery is in the optimal position, avoiding blocking and center of gravity problems.

[0143] The above are only some or preferred embodiments of the present utility model. Whether in terms of text or drawings, they cannot limit the scope of protection of the present utility model. Any equivalent structural transformation made using the content of the specification and drawings of the present utility model under the overall concept of the present utility model, or any direct / indirect application in other related technical fields, is included within the scope of protection of the present utility model.
