[0049] The embodiment of the present invention provides a photography auxiliary device, referring to Figures 1 to 4 The photography auxiliary device includes a first power supply body 100, the first power supply body 100 is provided with at least one expansion interface 10, and the expansion interface 10 is used to expand functional accessories 200;

[0050] The first power supply body 100 includes a housing 110 , a battery module 120 disposed in the housing 110 , and a power interface 130 disposed on a surface of the housing 110 . The power interface 130 is at least used for connecting to an external device.

[0051] The photography assist device proposed in this embodiment is an auxiliary device in the field of photography, which is used to provide assistance for photography work. The assistance includes, but is not limited to, power supply. The photography assist device can realize different auxiliary functions by configuring different expansion function accessories.

[0052] The photography assistance device primarily includes a first power supply body 100, which includes an expansion interface 10 for connecting to an expansion function accessory 200. The expansion function accessory 200 connects to the expansion interface 10 on the first power supply body 100, thereby being integrated with the first power supply body 100. The number of expansion interfaces 10 can be one or more, such as two or three, depending on the actual situation. When multiple expansion interfaces 10 are provided, the types of the expansion interfaces 10 can be all the same, all different, or some the same and others different. The expansion interfaces 10 can be of various types, including, but not limited to, threaded openings and wedge-shaped slots. Furthermore, it should be noted that the expansion interface 10 defined in this embodiment is not limited to a recessed connection structure such as a hole, hole, or slot; it can also be other types, such as a screw or hook. There is no limitation on the structural form of the expansion interface 10, as long as the expansion function accessory 200 can be connected to the first power supply body 100 through the expansion interface 10. Furthermore, one expansion interface 10 may be compatible with a plurality of expansion function accessories 200 , that is, a plurality of expansion function accessories 200 may be replaceably installed at one expansion interface.

[0053] The first power supply body 100 is a core component and includes a housing 110, a battery module 120, and a power interface 130. The housing 110 is generally rod-shaped or columnar, and has an internal cavity for accommodating components (such as the battery module 120). The housing 110 can be made of high-strength, lightweight engineering plastic, providing good protection and convenience. The housing 110 can include a body and a cover, which is located at one end of the body and serves to seal the cavity. The cover can be detachably connected to the body (such as a snap connection, screw connection, etc.), or it can be flexibly connected to the body (such as a rotating connection, sliding connection, etc.). The battery module 120 is housed in the cavity of the housing 110 and can use a large-capacity lithium battery pack to meet the power requirements of long-term shooting. The power interface 130 is located on the surface of the housing, such as a Type-C interface or USB interface, to facilitate connection to external devices and thus power external devices. The external device involved can be a photographic device, such as a video camera, a camera, etc., or other electrical equipment. In addition, if the expansion function accessory 200 is an electrical equipment, the first power supply body 100 can also connect the expansion function accessory 200 to the expansion function accessory 200 by plugging a power cord through its power interface 130 to supply power to the expansion function accessory 200. The number of power interfaces 130 can be one or more, and the setting position of the power interface 130 can be a circumferential side surface, an axial end surface, etc. of the shell 110. Of course, the user can also plug an external power source through the power interface 130 to charge the first power supply body 100.

[0054] The expansion function accessories 200 can be designed to suit different usage requirements. For example, a fill light module uses an LED array to provide auxiliary lighting for filming scenes; a fan module uses a high-power fan to provide air cooling for live broadcasts; and an audio acquisition module is equipped with a high-sensitivity microphone for high-quality audio recording. This is for illustrative purposes only and is not restrictive. The expansion function accessories 200 are designed based on actual needs. Each of these expansion function accessories 200 features a connection structure that matches the expansion interface 10 of the first power supply body 100, such as an internal threaded interface, a snap-on interface, or a magnetic interface, ensuring a secure connection and easy removal. There can be two or more expansion function accessories 200. The first power supply body 100 serves as the base carrier. Different expansion function accessories 200 can be assembled with the first power supply body 100 to create different product forms and be applied in different usage scenarios. Depending on the actual usage scenario, users can select or replace the corresponding expansion function accessories 200 from the multiple expansion function accessories 200 and use them in combination with the first power supply body 100.

[0055] In actual use, the first power supply body 100 can be used as a power supply, and is connected to the photographic equipment by plugging a power cord through the power interface 130. The battery module 120 can provide a stable power supply for the photographic equipment.

[0056] When the function needs to be expanded, the corresponding expansion function accessories 200 are selected according to the actual use requirements and assembled with the first power supply body 100 through a detachable connection. Based on the above example expansion function accessories 200, in specific applications, they may include the following:

[0057] Example 1: When installing the fill light module, the first power supply body 100 can be electrically connected to the fill light module, and the whole can be used as a fill light device in scenes such as live broadcast or video shooting;

[0058] Example 2: When the fan module is installed, the first power supply body 100 can be electrically connected to the fan module, and the whole can be used as a desktop fan in scenarios such as live broadcasting;

[0059] Example 3: When the audio acquisition module is installed, the first power supply body 100 can be electrically connected to the audio acquisition module, and the audio acquisition module can record audio and transmit the collected audio data to a photographic device or a storage device.

[0060] In the photography auxiliary device of the present invention, the first power supply body 100 is used as the core power supply module. The user can connect external devices through its power interface 130 to provide power supply for the external devices (such as cameras, etc.); on this basis, modular assembly can be performed through at least one expansion interface 10 on the first power supply body 100 and the expansion function accessories 200, thereby transforming the original single-function battery box into a multi-functional integrated photography auxiliary device. That is, the photography auxiliary device can flexibly configure and combine various expansion function accessories 200 according to different shooting requirements, thereby adapting to a variety of photography scenes and applying them, achieving a dual improvement in functionality and applicability, and can meet the diverse and professional usage needs in photography work.

[0061] In some embodiments, reference Figure 1 and Figure 2 , the expansion interface 10 includes:

[0062] A first expansion interface 101 is provided along the axial end surface of the housing 110 , and / or a second expansion interface 102 is provided on the circumferential side surface of the housing 110 .

[0063] The first expansion interface 101 is located on the axial end face of the shell 110. The choice of this position is consistent with the rod-shaped or columnar overall shape of the shell 110. Since the axial end face is the end area of ​​the shell 110, the space is relatively independent, which can provide a stable installation base for the expansion function accessory 200. Its structural form can be designed according to needs, such as threaded ports, snap-on structures, etc., as long as it can achieve a stable connection with the expansion function accessory 200. For example, when the expansion function accessory 200 is a fill light module, the fill light module is installed on the axial end face of the shell 110 through the first expansion interface 101.

[0064] The second expansion interface 102 is provided on the circumferential side of the housing 110. As the side area of ​​the housing 110, the circumferential side has greater space utilization. Similarly, its structural form also has diverse forms, such as wedge-shaped card slots and magnetic interfaces. Taking the fan module as an example, the fan module is installed on the circumferential side of the housing 110 through the second expansion interface 102. The fan's air outlet direction can be towards the camera operator or camera equipment, which can achieve a more efficient cooling effect in scenes such as live broadcasts.

[0065] It is worth noting that the expansion interface 10 may include only the first expansion interface 101, only the second expansion interface 102, or both the first expansion interface 101 and the second expansion interface 102. When both exist, the two can cooperate with each other to achieve simultaneous installation of multiple expansion function accessories 200, further enhancing the versatility of the device.

[0066] In some embodiments, reference Figure 1 and Figure 2 , the first expansion interface 101 includes:

[0067] A screw 1011 is provided along a first axial end surface of the housing 110 , and a threaded interface 1012 is provided along a second axial end surface of the housing 110 .

[0068] In this embodiment, in the axial direction of the housing 110, the first power supply body 100 can be connected to the corresponding extended function accessory 200 through the screw 1011 and the threaded interface 1012 respectively provided on the end surfaces of the housing. Specifically, the extended function accessory 200 with a screw hole structure can be directly screwed onto the screw 1011 on the first end surface of the housing 110 through threaded engagement, while the extended function accessory 200 with a screw structure can be screwed into the threaded interface 1012 on the second end surface of the housing 110, thereby achieving a stable and reliable detachable connection between the first power supply body 100 and the extended function accessory 200.

[0069] The threaded connection can withstand greater external forces than some traditional snap or magnetic connections. In complex usage scenarios such as movement and vibration of the photographic equipment, it can still ensure that the first power supply body 100 and the expanded function accessory 200 maintain a tight connection, avoiding functional failure due to loose connection, and effectively ensuring the smooth progress of shooting. The operation is simple and easy to understand. The photographer does not need to use additional tools, and can complete the installation and disassembly of the expanded function accessory 200 by manual twisting, which greatly shortens the equipment assembly time.

[0070] Furthermore, the bidirectional adaptability of screw 1011 and threaded interface 1012 significantly expands the types of connectable expansion accessories 200. Expansion accessories 200 of varying specifications and functions, as long as they possess a compatible threaded structure, can be connected and combined with the first power supply unit 100, further expanding the functional boundaries of the photography assistance device and meeting the professional needs of photographers in a wider range of shooting scenarios. Furthermore, the standardized threaded connection design facilitates the rapid integration of newly developed expansion accessories 200 into the photography assistance device system, reducing product upgrade costs and enhancing the product's market competitiveness and sustainable development capabilities.

[0071] In some embodiments, reference Figure 4 , the photography auxiliary device also includes:

[0072] The first expansion function accessory includes a first fill light 210 . The first fill light 210 is detachably disposed on the first power supply body 100 through the first expansion interface 101 and is electrically connected to the first power supply body 100 .

[0073] In this embodiment, the first fill light 210 has a connection structure compatible with the first expansion interface 101 on the first power supply body 100. The first fill light 210 is connected to the first expansion interface 101 so as to be detachably mounted on one end of the first power supply body 100. In conjunction with the previous embodiment, a screw 1011 is provided on the first end surface of the first power supply body 100 along the axial direction, and a threaded interface 1012 is provided on the second end surface. The first fill light 210 can be provided with a corresponding threaded opening or screw structure. Through threaded engagement, the first fill light 210 can be detachably mounted on one end of the first power supply body 100. The first fill light 210 can integrate an LED light-emitting component and a drive circuit. The drive circuit can be electrically connected to the battery module 120 of the first power supply body 100 via contact conduction or cable plug-in connection, thereby powering the first fill light 210 through the first power supply body 100.

[0074] The first fill light 210 can effectively improve the lighting conditions of the shooting scene. When shooting in low-light environments or at night, it can supplement the light to avoid problems such as heavy shadows and underexposure on the subject, making the image more saturated in color and clearer in details, thereby improving the quality and visual effects of the captured image. In specific use, the user can hold the first power supply body 100 and direct the first fill light 210 toward the subject to provide fill light. Usage scenarios include but are not limited to these.

[0075] Among them, the type of the first fill light 210 can be a pocket light. The small size and lightweight design of the pocket light type first fill light 210 make it have good portability, including but not limited to this.

[0076] In some embodiments, reference Figure 4 , the first fill light 210 includes:

[0077] The lamp holder 211 has a lamp control board inside, and a power supply interface 2111 electrically connected to the lamp control board is provided on the surface of the lamp holder 211. The lamp holder 211 is detachably connected to the first power supply body 100;

[0078] The lamp body 212 is rotatably mounted on the lamp holder 211 and is electrically connected to the lamp body control board.

[0079] In this embodiment, the first fill light 210 is mainly composed of a lamp holder 211 and a lamp body 212. The lamp holder 211 has an integrated lamp body control board, and a power interface 2111 electrically connected to the lamp body control board is provided on its surface. The power interface 2111 can be connected to the power interface 130 of the first power supply body 100 through a plug-in cable adapter to achieve power transmission and data interaction. Optionally, the power interface 2111 can adopt an interface type such as a Type-C interface. At the same time, the lamp holder 211 is provided with a threaded structure or a screw structure that matches the screw 1011 or the threaded interface 1012 of the first power supply body 100, and a detachable connection with the first power supply body 100 is achieved through threaded engagement. The lamp body 212 is rotatably mounted on the lamp holder 211 and is electrically connected to the lamp body control board in the lamp holder 211, and realizes the lighting function under the drive of the lamp body control board.

[0080] Among them, Figure 4 As shown, the lamp body 212 can be connected to the lamp holder 211 via a ball hinge structure. For example, the lamp holder 211 is provided with a hinge seat 213, and the lamp body 212 is provided with a spherical hinge portion 214. The spherical hinge portion 214 is assembled and accommodated in the hinge groove of the hinge seat 213, thereby realizing the rotatable setting of the lamp body 212 on the lamp holder 211. Users can freely adjust the illumination angle of the lamp body 212 according to the actual shooting scene and needs to accurately project light onto the subject, effectively avoiding blind spots and meeting the fill light requirements of various shooting angles.

[0081] In some embodiments, reference Figure 5 , the photography auxiliary device also includes:

[0082] The second expansion function accessory includes a second fill light 220 . The second fill light 220 is detachably disposed on the circumferential side of the first power supply body 100 through the second expansion interface 102 and is electrically connected to the first power supply body 100 .

[0083] In this embodiment, the second fill light 220 has a connection structure compatible with the second expansion interface 102 on the first power supply body 100. The second fill light 220 is connected to the second expansion interface 102 so as to be detachably mounted on the circumferential side of the first power supply body 100. For example, the circumferential side of the first power supply body 100 is provided with a magnetic interface or a snap-on interface (i.e., the second expansion interface 102), which has conductive contacts disposed therein and is electrically connected to the battery module 120 within the first power supply body 100. The second fill light 220 is provided with a magnetic structure or a snap-on structure corresponding to the position of the circumferential side interface of the first power supply body 100, and has conductive connection points on its contact surface. When the second fill light 220 is fixed to the circumferential side of the first power supply body 100 via magnetic attraction or snap-on means, the conductive connection points come into close contact with the conductive contacts of the first power supply body 100, thereby achieving electrical connection with the first power supply body 100. Alternatively, the second fill light 220 can be electrically connected to the first power supply 100 via a magnetic induction coil. For example, a high-frequency alternating current generating circuit and a transmitting coil are built into the circumferential side of the first power supply 100. The transmitting coil is electrically connected to the high-frequency alternating current generating circuit, which is in turn controlled by a control circuit within the first power supply 100. A receiving coil and a rectifier and voltage-stabilizing circuit are located at the position of the second fill light 220 corresponding to the first power supply 100. The receiving coil is connected to the rectifier and voltage-stabilizing circuit, and the output of the rectifier and voltage-stabilizing circuit is connected to the LED array and light control circuit within the second fill light 220. When the second fill light 220 approaches the circumferential side of the first power supply 100, the transmitting coil of the first power supply 100, driven by the high-frequency alternating current generating circuit, generates an alternating magnetic field. The receiving coil of the second fill light 220 induces an electromotive force in the alternating magnetic field, which is converted into stable direct current by the rectifier and voltage-stabilizing circuit to power the LED array.

[0084] The second fill light 220 can effectively improve the lighting conditions of the shooting scene. When shooting in low-light environments or at night, it can provide additional light to avoid problems such as heavy shadows and underexposure on the subject, making the image more saturated in color and clearer in details, thereby improving the quality and visual effects of the captured image. In specific use, the user can place the first power supply body 100 on an object such as a table, so that the first fill light 210 can be directed towards the subject for fill light. Usage scenarios include but are not limited to this.

[0085] The second fill light 220 may be a magnetic light, including but not limited to a magnetic light.

[0086] In some embodiments, reference Figure 5 The second fill light 220 includes:

[0087] The lamp board 221 is adapted to the circumferential side profile of the first power supply body 100 and is magnetically attached to the first power supply body 100 .

[0088] In this embodiment, the second fill light 220 adopts the structural form of a lamp board 221. The shape of the lamp board 221 is highly adapted to the circumferential side profile of the first power supply body 100 and is arc-shaped, which can achieve a close fit with the first power supply body 100. In addition, the second expansion interface 102 adopts a magnetic expansion interface structure. For example, the circumferential side of the first power supply body 100 is built-in with an annular magnetic array. The annular magnetic array is composed of a plurality of evenly distributed strong magnets. The back of the lamp board 221 is provided with a magnetic patch corresponding to the annular magnetic array to ensure that the lamp board 221 can be tightly magnetically attached to the circumferential side of the first power supply body 100. This magnetic attachment connection method greatly simplifies the installation process. The photographer only needs to bring the lamp board 221 close to the circumferential side of the first power supply body 100, and it can be automatically adsorbed and fixed under the action of magnetic force. No tools are required, and the connection is firm and stable. When disassembling, it can be separated with just a little force, which is convenient and efficient. In addition, the light board 221 has a light and thin structural design. After being adsorbed on the first power supply body 100, it is almost integrated with the first power supply body 100. The structure is compact and does not significantly increase the size and weight of the device, making it convenient for photographers to carry and operate.

[0089] In some embodiments, reference Figure 5 and Figure 6 , the photography auxiliary device also includes:

[0090] The third expansion function accessory includes a tripod 230 , which is detachably connected to the first power supply body 100 via the first expansion interface 101 .

[0091] In this embodiment, the tripod 230 has a connection structure that is compatible with the first expansion interface 101 on the first power supply body 100. The tripod 230 is connected to the first expansion interface 101 so as to be detachably arranged on the other end of the first power supply body 100. In combination with the aforementioned embodiment, a screw 1011 is provided on the first end face along the axial direction of the first power supply body 100, and a threaded interface 1012 is provided on the second end face. The tripod 230 can be provided with a corresponding threaded opening or screw structure. Through threaded engagement, the tripod 230 can be detachably arranged on the other end of the first power supply body 100.

[0106] In some embodiments, reference Figure 7 and Figure 9 The mount 240 has an arc-shaped assembly groove 2401 along one side of its thickness direction that matches the circumferential side profile of the first power supply body 100, and a V-shaped clamping portion 2402 for clamping with the photographic equipment on the other side.

[0107] In this embodiment, the mount 240 in the expanded functional accessory 200 has a targeted structural design, and one side thereof along the thickness direction is provided with an arc-shaped assembly groove 2401 that is adapted to the circumferential side profile of the first power supply body 100. The arc-shaped assembly groove 2401 adopts a high-precision injection molding process, and the inner wall is smooth and the size is precise. When the mount 240 is assembled to the first power supply body 100, the arc-shaped assembly groove 2401 can tightly fit the cylindrical profile of the first power supply body 100. Compared with the plane contact connection method, the contact area is greatly increased, and the risk of loose connection due to shaking is reduced. Among them, the conductive connector 241 is located in the arc-shaped assembly groove 2401. A V-shaped clamping portion 2402 is provided on the other side of the mount 240. The V-shaped clamping portion 2402 can be made of high-strength alloy material, and its two side walls are provided with anti-slip textures, and a bayonet 2402C can be set. The opening angle and dimensions of the V-shaped mounting portion 2402 have been optimized to accommodate the V-shaped slots of commonly available photographic equipment, such as shoulder mounts and tripods. When the V-shaped mounting portion 2402 of the mount 240 is engaged with the V-shaped slot on the photographic equipment, the elastic snap mechanism on the sidewall of the V-shaped slot automatically engages and locks with the snap-in notch 2402C on the V-shaped mounting portion 2402, ensuring that the mount 240 is securely mounted on the photographic equipment. To remove the mount 240, the mount 240 can be easily removed by pressing the unlocking button on the elastic snap mechanism to release the lock from the snap-in notch 2402C on the V-shaped mounting portion 2402. The universal design of the V-shaped mounting portion 2402 allows it to be adapted to mainstream brands and models of photographic equipment on the market, enabling quick installation and removal, effectively enhancing the versatility of the photography auxiliary device.

The hanging plate 250 can be a single plate or a composite plate composed of multiple plates stacked and connected. This embodiment does not limit this. The hanging plate 250 has a connection structure that is compatible with the second expansion interface 102 on the first power supply body 100. The hanging plate 250 is connected to the second expansion interface 102 so as to be detachably arranged on the circumferential side of the first power supply body 100. For example, based on the second expansion interface 102 provided on the circumferential side of the first power supply body 100, the hanging plate 250 is connected to the second expansion interface 102 by passing fasteners (such as bolts) to achieve a stable and detachable connection with the first power supply body 100.

[0112] In actual use, the user can mount the auxiliary photography device on a photographic device via the mounting plate 250, and power is provided by the first power supply unit 100. For example, the photographic device may be a shoulder-mounted camera, with a camera mounted on the mounting socket of the shoulder-mounted camera assembly. The auxiliary photography device is mounted on the rear side of the shoulder-mounted camera assembly via the mounting plate 250. When the camera battery is low, a cable can be connected directly to the camera via the power port 130 of the first power supply unit 100, providing power to the camera. The type of photographic device is not limited and can be other than this example.

[0113] Among them, the hanging plate 250 can adopt a structural design such as the V-shaped clamping part 2402 of the hanging seat 240, or it can also adopt a structural design such as a fastener (such as a bolt) to be detachably connected to the photographic equipment. This embodiment does not limit this.

[0114] In some embodiments, reference Figure 11 , the photography auxiliary device also includes:

[0115] The sixth expanded function accessory includes a second power supply body 260 , which has the same structure as the first power supply body 100 , and the second power supply body 260 is detachably connected to the first power supply body 100 .
