[0002] Photographic flash units are commonly used supplementary lighting devices in photography, widely applied in portrait photography, commercial photography, news photography, and many other fields. Existing photographic flash units typically use a hot shoe mount to attach to the camera or video camera for synchronized triggering. However, when photographers need to flexibly adjust the light source angle or when the camera is far from the subject, a fixed-mount flash unit is insufficient.

[0003] To overcome the limitations of fixed mounting, some photography accessory manufacturers have developed handheld mounts that allow flash units to be detached from the camera and used as independent light sources. These mounts typically provide mounting interfaces for securing the flash unit. However, existing handheld mounts only serve as physical mounting platforms and do not provide power to the flash unit, forcing photographers to carry spare batteries or replace the flash unit's built-in batteries, impacting shooting continuity and convenience.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Please see Figures 1 to 8 This embodiment provides a photographic device 100, which includes photographic equipment 20, equipment bracket 10, and an adapter cable (not shown in the figure). The photographic equipment 20 can be mounted on the equipment bracket 10 for easy handheld use by a user. The adapter cable is used to electrically connect the equipment bracket 10 and the photographic equipment 20 to supply power to the photographic equipment 20.

[0032] Please see Figure 1 and Figure 2 In some embodiments, the photographic equipment 20 includes an equipment body 21, a hot shoe 22, and a second electrical plug 23. The hot shoe 22 is disposed at the bottom of the equipment body 21, and the second electrical plug 23 is disposed on the side wall of the equipment body 21.

[0033] The photographic equipment 20 can be a flash, soft light, microphone, or other similar device. The bottom of the main body 21 of the equipment is provided with a hot shoe 22, which can be installed and fixed onto photographic equipment such as cameras and video cameras to achieve the installation and fixation of the photographic equipment 20.

[0034] The bottom surface of the hot shoe mount 22 is provided with a hot shoe contact 221, which is used to connect with the corresponding electrical contacts of the camera or camcorder for signal transmission. The bottom surface of the hot shoe mount 22 is also provided with an unlocking spring pin 222, which provides appropriate elastic support when the photographic equipment 20 is connected to or disconnected from the camera. When the photographic equipment 20 is mounted on the camera, the unlocking spring pin 222 is compressed, allowing the hot shoe mount 22 to be securely locked onto the camera; when it is necessary to remove the photographic equipment 20, the unlocking spring pin 222 returns to its elastic state, allowing the photographic equipment 20 to be easily removed.

[0035] The second power plug 23 is located on the side wall of the equipment body 21 and is used to connect to the adapter cable so that the equipment bracket 10 can provide power to the photographic equipment 20.

[0036] Please see Figure 2 and Figure 3 In some embodiments, the photographic equipment 20 also includes a knob 24. The knob 24 is threaded onto the top of the hot shoe 22 and is rotatable about the axis of the hot shoe 22. When the knob 24 is rotated clockwise and approaches the hot shoe 22, the knob 24 presses against the upper surface of the hot shoe 22 to secure it firmly to the camera or equipment holder 10, thus locking the photographic equipment 20 to the camera or equipment holder 10. When the knob 24 is rotated counterclockwise, the pressure on the hot shoe 22 is released, allowing the photographic equipment 20 to be detached from the camera or equipment holder 10.

[0037] Please see Figures 1 to 4 In some embodiments, the equipment holder 10 includes a housing 11, a connector 12, and a power supply unit 13.

[0038] The connector 12 is mounted on the housing 11 and is used for detachable connection with the photographic equipment 20. The power supply unit 13 includes a built-in power supply 131, a control module 132, and a first electrical plug 133. The built-in power supply 131 and the control module 132 are housed within the housing 11, and the control module 132 is electrically connected to the built-in power supply 131. The first electrical plug 133 is located on the side wall of the housing 11 and is electrically connected to the control module 132. The first electrical plug 133 is used for electrical connection with the photographic equipment 20, enabling the control module 132 to control the built-in power supply 131 to charge the photographic equipment 20.

[0039] Specifically, the housing 11 constitutes the main structure of the equipment stand 10, housing the power supply unit 13 and providing a grip base. A connector 12 is mounted on the housing 11 for detachable connection to the photographic equipment 20, ensuring quick installation and removal of the equipment. The connector 12 can be designed with different adapter interfaces depending on the type of photographic equipment 20, such as a cold shoe mount, snap-fit ​​structure, or magnetic connection, to meet the installation requirements of different photographic equipment 20.

[0040] The power supply unit 13 consists of a built-in power supply 131, a control module 132, and a first electrical plug 133. The built-in power supply 131 serves as an independent power source for the equipment stand 10, allowing the equipment stand 10 to provide power to the photographic equipment 20 without an external power source. The control module 132 is used to regulate and manage the power supply process, ensuring charging stability and safety, such as voltage regulation and overcharge protection. The first electrical plug 133 is located on the side wall of the housing 11 and can be electrically connected to the corresponding second electrical plug 23 on the photographic equipment 20, thereby establishing a power transmission path.

[0041] After the photographic equipment 20 is mounted onto the connector 12 on the equipment stand 10, the first power plug 133 can be connected to the second power plug 23 of the photographic equipment 20 via an adapter cable. The control module 132 then initiates the charging process, enabling the photographic equipment 20 to draw power from the built-in power supply 131 of the equipment stand 10. This avoids the problem of traditional handheld docks being unable to charge, improves the battery life of the photographic equipment, and reduces the risk of shooting interruptions due to insufficient power. It is also more stable during use, improving the ease of operation for photographers.

[0042] It is conceivable that in other embodiments, the connector 12 of the equipment holder 10 can employ different fixing methods, such as magnetic connection or quick-release clips, to accommodate different types of photographic equipment 20. The first electrical plug 133 can be designed as a flexible contact, a Type-C interface, or an aviation connector, etc., to improve versatility. The built-in power supply 131 can be a replaceable battery, allowing users to replace the battery as needed, thereby extending the usage time of the equipment holder 10.

[0043] Please see Figure 5 In some embodiments, the housing 11 includes an outer shell 111 and an inner sleeve 112. The outer shell 111 has a receiving cavity, a built-in power supply 131 is fixed to the bottom of the receiving cavity, and the sleeve 112 is received at the top of the receiving cavity. A control module 132 is fixed inside the sleeve 112 and is capable of moving with the sleeve 112 within the receiving cavity to connect with the built-in power supply 131.

[0044] Specifically, the outer casing 111 includes a main body 1111, a bottom cover 1112, a top cover 1113, a front decorative cover 1114, and a rear decorative cover 1115. The main body 1111 has a columnar structure with openings at both ends and a hollow interior. The bottom cover 1112 is installed at the bottom of the main body 1111 to close the bottom opening. The bottom cover 1112 may have a connection hole 11121 for threaded connection with an external support, allowing the photographic device 100 to be fixed to an external support such as a tripod or photographic pole. The top cover 1113 is installed at the bottom of the main body 1111 to close the top opening. A connecting seat 12 is provided on the top surface of the top cover 1113 for connection with the hot shoe 22 of the photographic equipment 20. The front decorative cover 1114 and the rear decorative cover 1115 are set on the front and rear side walls of the shell body 1111 to beautify the appearance of the equipment bracket 10 and prevent external forces from impacting its internal structure, thus playing a certain protective role.

[0045] In some embodiments, the inner sleeve 112 has a mounting cavity for mounting and fixing the control module 132, allowing the control module 132 to move downwards within the cavity along with the inner sleeve 112, enabling the control module 132 to connect to the interface of the built-in power supply 131 for power transmission. When it is necessary to replace the internal module, the inner sleeve 112 and the control module 132 can be moved upwards as a whole, disconnecting the control module 132 from the built-in power supply 131 for easy maintenance or replacement.

[0046] Please see Figure 8 In some embodiments, the connecting seat 12 includes a base plate 121 and a metal pressure plate 122. The base plate 121 is fixed to the top surface of the housing 11, and the base plate 121 has an open front end groove 1211 for engaging with the hot shoe 22 of the photographic equipment 20. The metal pressure plate 122 is disposed inside the base plate 121, and spring pieces 1221 are provided on both sides of the metal pressure plate 122. The spring pieces 1221 are accommodated in the groove 1211 and are used to elastically abut against the hot shoe 22 of the photographic equipment 20.

[0047] The base plate 121 has a groove 1211 that allows the hot shoe 22 of the photographic equipment 20 to slide into and lock into place along the extension direction of the groove 1211, enabling quick installation and disassembly. A metal pressure plate 122 is disposed within the base plate 121, and spring tabs 1221 are provided on both sides of the plate. The spring tabs 1221 are housed within the groove 1211 and are used to elastically abut against the hot shoe 22 of the photographic equipment 20, thereby providing appropriate clamping force during installation to ensure that the photographic equipment 20 is not easily loosened after being locked in, while allowing appropriate external force to be applied to disassemble when necessary.

[0048] Please see Figure 8The top cover 1113 is provided with a mounting groove, and the mounting groove is provided with a positioning boss 11132 and a screw hole 11131 for positioning and mounting the base plate 121, so that the base plate 121 can be fixed to the top cover 1113 by screws, so as to ensure that the connecting seat 12 can be stably fixed to the housing 11.

[0049] In some embodiments, a hot shoe contact groove 11133 is also provided in the mounting slot, and the base plate 121 is provided with an opening that meets the hot shoe contact groove 11133, so that when the hot shoe mount 22 is installed with the equipment bracket 10, the hot shoe contact 221 of the photographic equipment 20 can be accommodated in the hot shoe contact groove 11133 to prevent the hot shoe contact 221 from being scratched. In addition, the base plate 121 and the metal pressure plate 122 are provided with through holes 123, which are used to accommodate the unlocking spring pin 222 on the hot shoe mount 22 to prevent damage to the unlocking spring pin 222.

[0050] Please see Figure 6 and Figure 7 In some embodiments, the control module 132 includes a boost module electrically connected to the built-in power supply 131 to boost the voltage output of the built-in power supply 131.

[0051] Furthermore, the boost module includes a first circuit board 1321 and a transformer 1322. The first circuit board 1321 has a first electrical connection terminal 13211 on the side facing the built-in power supply 131. The first electrical connection terminal 13211 is used for electrical connection with the built-in power supply 131, thus electrically connecting the first circuit board 1321 to the built-in power supply 131. The transformer 1322 is located on the side of the first circuit board 1321 opposite to the electrical connection terminal, and is used to boost the current output from the built-in power supply 131.

[0052] Specifically, the main function of the boost module is to adjust the output voltage of the built-in power supply 131 to meet the voltage requirements of the photographic equipment 20. The boost module consists of a first circuit board 1321, a transformer 1322, and multiple capacitors. The circuits on the first circuit board 1321 are responsible for voltage regulation and control signal transmission.

[0053] In other embodiments, the photographic equipment 20 is specifically a flash unit, which may include a flash tube, a boost circuit, and a battery. The boost circuit connects the battery to the flash tube, enabling the boost circuit to convert the battery's power supply voltage into a high voltage of several hundred volts (e.g., 330V) and output it to the flash tube. The flash unit's second power connector is located on the boost circuit, allowing the output of the transformer 1322 within the equipment holder 10 to be connected in parallel with the output of the flash unit's built-in boost circuit via an adapter cable, thereby improving the flash unit's recycle speed.

[0054] In one example, transformer 1322 can boost an input voltage from several volts (V) to tens of volts to hundreds of volts (e.g., 330V) to supply the flash tube.

[0055] In some embodiments, the first electrical connection terminal 13211 on the first circuit board 1321 is used to electrically connect with the second electrical connection terminal 1313 of the built-in power supply 131 to achieve stable power transmission. This allows the DC power from the built-in power supply 131 to enter the first circuit board 1321 through the first electrical connection terminal 13211, where it is processed in the circuitry of the first circuit board 1321 and then transmitted to the transformer 1322 for voltage boosting.

[0056] The low voltage provided by the built-in power supply 131 is converted into a high voltage that meets the requirements of the photographic equipment 20, thereby ensuring that the photographic equipment 20 can work stably. By integrating a boost module into the equipment holder 10, direct power supply to the photographic equipment 20 is achieved, avoiding the problem that traditional handheld bases cannot meet different voltage requirements, and improving the applicability of the equipment holder 10.

[0057] Please see Figure 5 In some embodiments, the control module 132 further includes a charging module electrically connected to the boost module. A first plug 133 is fixed to the charging module; the charging module can communicate with an external charging device to charge the built-in power supply 131.

[0058] Furthermore, the charging module includes a second circuit board 1323, a charging interface 1324, and a wiring socket 1325. The second circuit board 1323 is electrically connected to the first circuit board 1321; the wiring socket 1325 is disposed on the second circuit board 1323; the inner end of the first plug 133 is inserted into the wiring socket 1325, thereby electrically connecting the first plug 133 to the second circuit board 1323. The charging interface 1324 is disposed on the second circuit board 1323 and is used for electrical connection with an external charging device to charge the built-in power supply 131.

[0059] Specifically, the second circuit board 1323 is connected and fixed to the first circuit board 1321 by two fixing posts 1329, and electrical conduction is achieved through the metal channels within the fixing posts 1329. A wiring socket 1325 is provided on the second circuit board 1323 to connect to the inner end of the first electrical plug 133, thus achieving electrical connection between the first electrical plug 133 and the second circuit board 1323. This plug-in design ensures convenient modular assembly while improving the stability of the electrical connection, preventing poor contact due to vibration or mechanical stress during system use.

[0060] The charging interface 1324 on the second circuit board 1323 can serve as a connection port for external charging devices. The charging interface 1324 can be a Type-C port, a USB port, a DC port, or a wireless charging module. The external charging device can be a charging adapter, a power bank, or other DC power supply device. It charges the built-in power supply 131 through the charging interface 1324, allowing the device to replenish its power at any time during use and improving its battery life.

[0061] Please see Figure 7 In some embodiments, the control module 132 further includes a third circuit board 1326, a switch button 1327, and an indicator light 1328. The third circuit board 1326 is disposed on and electrically connected to the second circuit board 1323. The switch button 1327 is disposed on the third circuit board 1326 and extends from the side wall of the housing 11; the switch button 1327 is used to control the flow of current from the built-in power supply 131 to the first electrical plug 133. The indicator light 1328 is disposed on the third circuit board 1326 and is used to display the usage status of the equipment holder 10.

[0062] Specifically, the switch button 1327, serving as a user interaction component, is mounted on the third circuit board 1326 and partially extends out of the side wall of the housing 11, allowing for convenient operation by the user. When the user presses the switch button 1327, the third circuit board 1326 sends a control signal to the second circuit board 1323, causing current to flow and thus powering the photographic equipment 20; when the user presses the switch button 1327 again, the current is cut off, stopping the power supply.

[0063] Indicator light 1328 is mounted on the third circuit board 1326 and displays the usage status of the equipment holder 10. Indicator light 1328 can display different colors or flashing patterns depending on the connection status of the built-in power supply 131. For example, when the power is on and working normally, indicator light 1328 is constantly lit; when the battery is low, indicator light 1328 flashes to prompt the user to charge; when the device is in standby mode, indicator light 1328 is off. This visual status feedback allows the user to intuitively judge the device's working status and avoid equipment malfunctions caused by insufficient power or misoperation.

[0064] Please see Figure 7In some embodiments, the built-in power supply 131 includes a plurality of rechargeable batteries 1311 and a fourth circuit board 1312. The plurality of rechargeable batteries 1311 are electrically connected to the fourth circuit board 1312. The fourth circuit board 1312 has a second electrical connection terminal 1313 on its side opposite to the rechargeable batteries 1311. The second electrical connection terminal 1313 matches a first electrical connection terminal 13211 on a first circuit board 1321. When the first electrical connection terminal 13211 is plugged into the second electrical connection terminal 1313, the first circuit board 1321 is electrically connected to the rechargeable batteries 1311.

[0065] Specifically, the fourth circuit board 1312 is located at one end of the multiple rechargeable batteries 1311 to manage the energy distribution of the rechargeable batteries 1311, ensure the stability of the output voltage and current, and support necessary power protection functions such as overcharge, over-discharge and short circuit protection.

[0066] The fourth circuit board 1312 has a second electrical connection terminal 1313 on its side opposite to the rechargeable battery 1311. The second electrical connection terminal 1313 can be plugged into the first electrical connection terminal 13211 on the first circuit board 1321. The first electrical connection terminal 13211 and the second electrical connection terminal 1313 can be connected by a socket and pin to quickly establish an electrical connection without the need for additional complex wiring, which facilitates replacement and maintenance.

[0067] Of course, in some other embodiments, the connection between the second electrical connection terminal 1313 and the first electrical connection terminal 13211 can be achieved by using a contact point structure or other devices.
