[0002] With the rise of social media, people are keen to use image capture devices to take photos and videos. As the video shooting and time-lapse photography functions of image capture devices become more widespread, the power consumption of image capture devices has increased significantly, and the demand for battery life has increased substantially.

[0003] In related technologies, image capture devices primarily rely on external chargers or independent power banks for charging. The former requires a fixed outlet, making it unsuitable for outdoor and mobile shooting needs, while the latter, though portable, suffers from issues such as tangled cables and loose connections. This results in limitations in the charging methods for image capture devices, including restricted usage scenarios and unstable connections. Consequently, the charging process for image capture devices is cumbersome and inflexible, making it difficult to replenish power promptly in diverse shooting scenarios. Utility Model Content

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0011] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an image capture system provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the image capture system includes a support device 100 and an image capture device 200. The support device 100 fixes the image capture device 200 inside it, using its own structure and related components to fix the image capture device 200 in a stable position. It can also fix other accessories, such as microphones, flashes, monitors, follow focus devices, handheld stabilizers, etc., through various connection points and clamps on the support device 100 to meet the needs of expanding the image capture device 200 in different shooting scenarios.

[0012] When the image capture device 200 needs charging, in related technologies, an external charger or a separate power bank can be used to charge it. However, using an external charger is limited by fixed power outlets, resulting in poor charging flexibility. If the image capture device 200 is fixed to the bracket device 100, the connecting cable needs to pass through relevant components on the bracket device 100 or through other accessories to connect to the image capture device 200, making the wiring complex and prone to causing unstable charging.

[0013] To address the aforementioned issues, this utility model provides a support device that can charge the image capture device while it is mounted on the support device, thereby improving the flexibility and stability of charging.

[0014] Specifically, please refer to Figure 2 ,like Figure 2 As shown, the bracket device 100 includes a bracket body 20 and a first interface 30. The bracket body 20 has a accommodating space for accommodating an image capture device. The bracket body 20 includes a first surface 20a, which is opposite to the lens of the image capture device 200.

[0015] The first interface 30 is movably located on the first surface 20a, and its movability is diverse. For example, the first interface 30 can rotate around a rotation axis at multiple angles to adjust its orientation to adapt to different connection angles. The first interface 30 can also twist at a certain angle along its own axis to compensate for installation deviations and ensure precise docking. The first interface 30 can also extend and retract along a set direction, flexibly meeting connection requirements of different distances by changing the extension length. Thus, the movable location of the first interface 30 on the first surface 20a can significantly improve the adaptability of the support equipment in various scenarios.

[0016] When the image capture device 200 is mounted on the bracket device 100, the first interface 30 is electrically connected to the image capture device 200. The first interface 30 can be electrically connected to the image capture device 200 by insertion; therefore, the first interface 30 can be any interface that matches the jack on the image capture device 200, such as a TYPE-C interface, a pogo pin interface, or a Mini USB interface. The first interface 30 can also be electrically connected to the image capture device 200 by magnetic attraction; therefore, the first interface 30 can be a magnetic interface.

[0017] The bracket device is also equipped with an expansion interface 40, which is an interface for connecting auxiliary devices. Auxiliary devices can be selfie sticks, tripods, external microphones, and fill lights, etc. The expansion interface 40 can include 1 / 4 screw thread, folding two-prong interface, etc.

[0018] A 1 / 4" screw thread is used for connection; for example, screwing the 1 / 4" screw at one end of the selfie stick into the 1 / 4" screw thread allows for a secure connection between the image capture device 200 and the selfie stick. A folding two-claw interface typically consists of a connecting component with two foldable "claw-like" structures. The claws can be fixed to specific parts of the device (such as the frame of the image capture device 200) by clamping or snapping. When connecting the selfie stick, the two claws are unfolded to clamp the device, and locking them allows for extended use. The folded state makes it easy to store and carry.

[0019] like Figure 2 As shown, the expansion interface 40 also includes a magnetic quick-release interface 41, an audio interface 42, and a cold shoe 43. The magnetic quick-release interface 41 is located on the bottom surface of the bracket body 20. It is an interface that uses magnetism to achieve quick connection and disassembly. Its structure generally includes a magnetic module and a matching connecting component. When a selfie stick or other device with a magnetic end approaches the magnetic interface on the image capture device 200 or the stabilizer, it can be quickly attracted and fixed. When disassembling, it can be easily pulled apart.

[0020] An audio interface 42 is located on the top surface of the bracket body 20 and is used to connect an audio device to the image capture device 200. The audio device can be an audio acquisition device, an audio playback device, or a terminal integration device. The audio acquisition device can be a microphone or voice recorder, the audio playback device can be headphones, speakers, or other similar devices, and the terminal integration device can be a mobile phone, computer, or television. The audio device and the image capture device 200 are electrically connected via the audio interface 42. The audio interface 42 receives the sound signal acquired by the audio acquisition device and transmits the acquired sound signal to the image capture device 200. The audio interface 42 can also transmit the audio signal output by the image capture device 200 to the audio playback device for playback.

[0021] The cold shoe 43 is located on the top surface of the bracket body 20, providing a stable mounting base for accessories such as flash units, microphones, monitors, fill lights, and tripods. The cold shoe 43 typically has a metal or plastic interface with a slot, and the accessory end is designed with a corresponding clip for electrical connection to the slot. After electrical connection, it is locked with screws or clips to ensure the accessory does not wobble during shooting. In some embodiments, the cold shoe 43 may also integrate contacts to simultaneously achieve fixing and power supply or fixing and data transmission functions.

[0022] It should be noted that the number and location of the expansion interfaces 40 can be set as needed. Figure 2 The present invention is illustrated by an example of a magnetic quick-release interface 41, an audio interface 42, and a cold shoe 43, and by an example of the magnetic quick-release interface 41 being located at the bottom of the bracket body 20, and the audio interface 42 and the cold shoe 43 being located at the top of the bracket body 20. However, the present invention does not impose any restrictions on the number or position of the expansion interfaces 40.

[0023] Please see Figure 3 , Figure 3 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 3 As shown, the bracket device 100 also includes a power supply circuit 10, which is electrically connected to the first interface 30. When the image capture device 200 is installed on the bracket device 100, the image capture device 200 is electrically connected to the first interface 30, and the power supply circuit 10 charges the image capture device 200 through the first interface 30.

[0024] Therefore, the bracket device 100 combines charging and support functions. When the image capture device 200 is installed on the bracket device 100, the bracket device 100 can charge the image capture device 200 without the need for an additional charger or power bank, making charging more convenient and flexible, and expanding the range of application scenarios. The bracket device 100 charges the image capture device 200 through its own interface, ensuring a stable connection and improving charging stability.

[0025] In some embodiments, please refer to the following: Figure 2 and Figure 3 The bracket device 100 also includes a second interface 50, and the bracket body 20 also includes a second surface 20b. The second interface 50 is disposed on the second surface 20b, which is opposite to the lens of the image capture device 200. The second interface 50 is connected to the power supply circuit 10, and when the external charger 300 is connected to the bracket device 100, the second interface 50 is electrically connected to the external charger 300.

[0026] The external charger 300 and the second interface 50 are electrically connected by insertion or by magnetic attraction. The power supply circuit 10 outputs the first charging current from the external charger 300 to the image capture device 200 to charge the image capture device 200. The power supply circuit 10 also receives the second charging current from the external charger 300 and converts it into electrical energy for storage, so that the external charger 300 can charge the support device 100.

[0027] Therefore, when the external charger 300 is connected to the bracket device 100 through the second interface 50, the external charger 300 charges the image capture device 200 through the power supply circuit 10 to replenish the power of the image capture device 200, and also charges the bracket device 100 through the power supply circuit 10 to replenish the power of the bracket device 100. Thus, when there is no external charger 300, the bracket device 100 can replenish the power of the image capture device 200 in a timely manner.

[0028] Please see Figure 4 , Figure 4 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 4 As shown, the bracket device 100 includes a first interface 30, a second interface 50, and a power supply circuit 10, and the power supply circuit 10 includes a first power supply circuit 11, which is located between the first interface 30 and the second interface 50.

[0029] When the external charger 300 is electrically connected to the second interface 50, the external charger 300 outputs a first charging current to the first power supply circuit 11. The first power supply circuit 11 receives the first charging current and outputs the first charging current to the image capture device 200 to charge the image capture device 200.

[0030] In some embodiments, please continue reading Figure 4 The power supply circuit 10 also includes a second power supply circuit 12, which is connected to both the first interface 30 and the first power supply circuit 11. When the image capture device 200 is electrically connected to the first interface 30, the second power supply circuit 12 charges the image capture device 200. When the external charger 300 is electrically connected to the second interface 50, the second power supply circuit 12 receives the second charging current output by the external charger 300, converts the second charging current into electrical energy for storage, and the first power supply circuit 11 outputs the first charging current output by the external charger 300 to the image capture device 200 to charge the image capture device 200.

[0031] Therefore, the power supply circuit 10 is divided into two branches: a first power supply circuit 11 and a second power supply circuit 12. When the image capture device 200 is electrically connected to the first interface 30, the second power supply circuit 12 charges the image capture device 200. When the external charger 300 is electrically connected to the second interface 50, the external charger 300 charges the image capture device 200 through the first power supply circuit 11 and charges the support device 100 through the second power supply circuit 12.

[0032] In some embodiments, please continue reading Figure 4 The support device 100 also includes a controller 13, which is connected to the first power supply circuit 11 and the second power supply circuit 12 respectively. The controller 13 detects the connection status of the first interface 30 and the second interface 50 to control the working status of the first power supply circuit 11 and the second power supply circuit 12 respectively.

[0033] The controller 13 detects the electrical connection status between the first interface 30 and the image capture device 200. If the detection result indicates that the image capture device 200 is electrically connected to the first interface 30, the controller 13 controls the second power supply circuit 12 to charge the image capture device 200.

[0034] The controller 13 detects the electrical connection status between the second interface 50 and the external charger 300. If the detection result indicates that the external charger 300 is electrically connected to the second interface 50, the controller 13 controls the operation of the first power supply circuit 11, so that the external charger 300 charges the image capture device 200 through the first power supply circuit 11. The controller 13 also controls the operation of the second power supply circuit 12, so that the second power supply circuit 12 stores the electrical energy output by the external charger 300, thereby enabling the external charger 300 to charge the bracket device 100.

[0035] Please see Figure 5 , Figure 5 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 5 As shown, the first power supply circuit 11 includes a first switch unit 111. The first end of the first switch unit 111 is connected to the second interface 50, the second end of the first switch unit 111 is connected to the first interface 30 at the first node a, and the control end of the first switch unit 111 is connected to the controller 13.

[0036] The first switching unit 111 can be a transistor, MOSFET, thyristor, or other switching transistor. The control terminal of the first switching unit 111 receives a control signal sent by the controller 13, which controls the first switching unit 111 to be turned on or off. When the first switching unit 111 is in the on state, the first interface 30 and the second interface 50 are connected; when the first switching unit 111 is in the off state, the first interface 30 and the second interface 50 are disconnected.

[0037] Therefore, when the external charger 300 is electrically connected to the second interface 50, the control signal controls the first switch unit 111 to be in the conducting state, and the first charging current output by the external charger 300 is output to the image capture device 200 through the first switch unit 111 and the first interface 30 to charge the image capture device 200.

[0038] In some embodiments, please continue reading Figure 5 The second power supply circuit 12 includes a first energy storage unit 121 and a charge / discharge management unit 122. The charge / discharge management unit 122 is connected to the first switching unit 111 in two ways. The first way is that one end of the charge / discharge management unit 122 is connected to the first switching unit 111 and the first interface 30 at the first node a, and the other end of the charge / discharge management unit 122 is connected to the first energy storage unit 121. The charge / discharge management unit 122 is also connected to the controller 13. The second way is that one end of the charge / discharge management unit 122 is connected to the first switching unit 111 and the second interface 50, and the other end of the charge / discharge management unit 122 is connected to the first energy storage unit 121. The charge / discharge management unit 122 is also connected to the controller 13. Figure 5 The first method is shown as an example.

[0039] When the image capture device 200 is electrically connected to the first interface 30, the first energy storage unit 121 outputs a first voltage, and the charge and discharge management unit 122 boosts the first voltage to obtain a second voltage, and outputs the second voltage to the image capture device 200 to charge the image capture device 200.

[0040] When the external charger 300 is electrically connected to the second interface 50, the external charger 300 outputs a second charging current to the charge / discharge management unit 122. The controller 13 sends a first charging power of the first energy storage unit 121 to the charge / discharge management unit 122. The charge / discharge management unit 122 adjusts the second charging current based on the first charging power to obtain a first target current, and outputs the first target current to the first energy storage unit 121 to charge the first energy storage unit 121.

[0041] The first target current generated by the charge and discharge management unit 122 is different if the first charging power is different, that is, the charging current for charging the first energy storage unit 121 is different, which in turn determines the electrical energy transmitted to the first energy storage unit 121.

[0042] In some embodiments, the power supply circuit 10 further includes a second energy storage unit 123, which is connected to the charge / discharge management unit 122, and the initial charge of the second energy storage unit 123 is less than the initial charge of the first energy storage unit 121. That is, when neither the first energy storage unit 121 nor the second energy storage unit 123 is performing a charge / discharge operation, the charge stored in the second energy storage unit 123 is less than the charge stored in the first energy storage unit 121.

[0043] The battery capacity is expressed in terms of State of Charge (SOC), which represents the percentage of the battery's remaining usable capacity and is used to measure the current available capacity of the energy storage unit.

[0044] For example, the initial charge of the first energy storage unit 121 is 90%, and the initial charge of the second energy storage unit 123 is 80%. The initial charge of the first energy storage unit 121 is greater than the initial charge of the second energy storage unit 123.

[0045] When the image capture device 200 is electrically connected to the first interface 30, if the real-time power of the first energy storage unit 121 is less than or equal to the first power threshold, the second energy storage unit 123 outputs a third voltage. The charge and discharge management unit 122 boosts the third voltage to obtain a fourth voltage and outputs the fourth voltage to the image capture device 200 to charge the image capture device 200.

[0046] The first power threshold can be set as needed. In this embodiment, the first power threshold is 2%, that is, when the real-time SOC of the first energy storage unit 121 is less than or equal to 2%, the second energy storage unit 123 continues to charge the image capture device 200.

[0047] It should be noted that both the first energy storage unit 121 and the second energy storage unit 123 are rechargeable devices, such as batteries.

[0048] Therefore, when the real-time power of the first energy storage unit 121 with high power is low and cannot meet the charging needs of the image capture device 200, in this embodiment, the second energy storage unit 123 is used to charge the image capture device 200 so as to replenish the power of the image capture device 200 in a timely manner.

[0049] In some embodiments, when the external charger 300 is electrically connected to the second interface 50, the charge and discharge management unit 122 receives the first charging power sent by the controller 13, and adjusts the second charging current to the first target current based on the first charging power to charge the first energy storage unit 121.

[0050] As the charging process progresses, the real-time charge level of the first energy storage unit 121 continuously increases. When the real-time charge level of the first energy storage unit 121 reaches the rated charge level, the charge / discharge management unit 122 receives the second charging power of the second energy storage unit 123 sent by the controller 13. Then, the charge / discharge management unit 122 adjusts the second charging current based on the second charging power to obtain a second target current, and outputs the second target current to the second energy storage unit 123 to charge the second energy storage unit 123.

[0051] Therefore, when the external charger 300 is electrically connected to the second interface 50, it first charges the first energy storage unit 121 with a higher initial charge, and after the first energy storage unit 121 is fully charged, it then charges the second energy storage unit 123 with a lower initial charge.

[0052] Please see Figure 6 , Figure 6 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 6 As shown, the power supply circuit 10 also includes a current detection circuit 14, which is connected between the first node a and the first interface 30, and is also connected to the controller 13.

[0053] Optionally, the current detection circuit 14 may employ a Hall sensor detection scheme, a shunt resistor detection scheme, a current transformer detection scheme, or a dedicated current detection chip.

[0054] When the external charger 300 is electrically connected to the second interface 50, the external charger 300 outputs a first charging current to the first power supply circuit 11 to charge the image capture device 200. The current detection circuit 14 detects the first charging current to obtain a detection current and outputs the detection current to the controller 13. The controller 13 then determines the first charging power or the second charging power based on the detection current.

[0055] The controller 13 can determine the current state of the image capture device 200 based on the detected current, and then determine the charging power to the first energy storage unit 121 and the second energy storage unit 123 based on the state of the image capture device 200.

[0056] Specifically, if the detected current is greater than the first current threshold, the controller 13 determines that the image capture device 200 is currently in operation, and then determines the first charging power or the second charging power as the first power.

[0057] If the detected current is less than or equal to the first current threshold and greater than the second current threshold, the controller 13 determines that the image capture device 200 is currently in a screen-off standby state, and then determines the first charging power or the second charging power as the second power.

[0058] If the detected current is less than or equal to the second current threshold, the controller 13 determines that the image capture device 200 is currently in a powered-off state, and then determines the first charging power or the second charging power as the third power.

[0059] The first and second current thresholds can be set as needed. The first, second, and third power are all based on the rated power of the external charger 300, with the first power being less than the second power and the second power being less than the third power.

[0060] For example: if the rated power of the charger is P, then the first power P1 = P - 10W, the second power P2 = P - 2.5W, and the third power P3 = P - 0.5W.

[0061] If the first current threshold is 500mA and the second current threshold is 100mA, then if the detected current is greater than 500mA, the first charging power or the second charging power is determined to be the first power P1. If the detected current is less than or equal to 500mA and greater than 100mA, then the first charging power or the second charging power is determined to be the second power P2. If the detected current is less than or equal to 100mA, then the first charging power or the second charging power is determined to be the third power P3.

[0062] The following explanation uses a specific example to illustrate the logic for determining the first, second, and third power. Here, the current detection circuit 14 employs a Hall sensor detection scheme, setting the first current threshold to 500mA, the second current threshold to 100mA, and the charger's rated power to P. Therefore, the first power is determined to be P-10W, the second power to be P-2.5W, and the third power to P-0.5W.

[0063] When the current I detected by the Hall sensor is greater than 500mA, the controller 13 determines that the image capture device 200 is in a working state, such as shooting state, preview state or saving state, and then determines that the first charging power or the second charging power is P-10W. According to the power of P-10W, the first energy storage unit 121 is charged first, and then the second energy storage unit 123 is charged.

[0064] When the current detected by the Hall sensor is 500mA≥I>100mA, the controller 13 determines that the image capture device 200 is in a screen-off standby state, and then determines that the first charging power or the second charging power is P-2.5W. According to the power of P-2.5W, the first energy storage unit 121 is charged first, and then the second energy storage unit 123 is charged.

[0065] When the current I detected by the Hall sensor is ≤100mA, the controller 13 determines that the image capture device 200 is in a power-off state, and then determines that the first charging power or the second charging power is P-0.5W. According to the power of P-0.5W, the first energy storage unit 121 is charged first, and then the second energy storage unit 123 is charged.

[0066] Therefore, in this embodiment, the controller 13 determines the current state of the image capture device 200 based on the detected current, and determines the first charging power or the second charging power according to the principle of prioritizing power supply to the image capture device 200, so as to prioritize ensuring the power demand of the image capture device 200 and replenish the power of the image capture device 200 in a timely manner.

[0067] Please see Figure 7 , Figure 7 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 7 As shown, the charge / discharge management unit 122 includes a first charge / discharge management chip 1221 and a second charge / discharge management chip 1222. The first terminal of the first charge / discharge management chip 1221 is connected to the first energy storage unit 121, and the second terminal of the first charge / discharge management chip 1221 is connected to the first node a. The first charge / discharge management chip 1221 is also connected to the controller 13. The first terminal of the second charge / discharge management chip 1222 is connected to the second energy storage unit 123, and the second terminal of the second charge / discharge management chip 1222 is connected to the first node a. The second charge / discharge management chip 1222 is also connected to the controller 13.

[0068] When the image capture device 200 is electrically connected to the first interface 30, the first energy storage unit 121 outputs a first voltage. The first charge / discharge management chip 1221 boosts the first voltage to obtain and output a second voltage to charge the image capture device 200. As the energy of the first energy storage unit 121 is consumed, when the real-time energy level of the first energy storage unit 121 is less than or equal to a first energy threshold, the second energy storage unit 123 outputs a third voltage. The second charge / discharge management chip 1222 boosts the third voltage to obtain and output a fourth voltage to continue charging the image capture device 200.

[0069] The first power threshold can be set as needed. In this embodiment, the first power threshold is 2%. That is, when the real-time SOC of the first energy storage unit 121 is less than or equal to 2%, the second energy storage unit 123 is switched to charge the image capture device 200. This can prevent the first energy storage unit 121 from running out of power.

[0070] In some embodiments, when the first energy storage unit 121 charges the image capture device 200, the second charge and discharge management chip 1222 also disables the charging enable to prevent the electrical energy output by the first energy storage unit 121 from charging the second energy storage unit 123, thereby avoiding the charging self-circulation phenomenon and enabling timely replenishment of power to the image capture device 200.

[0071] Therefore, when charging the image capture device 200, the first energy storage unit 121, which initially has a high charge level, first charges the image capture device 200, and prevents the electrical energy output by the first energy storage unit 121 from being transferred to the second energy storage unit 123, thus avoiding a charging self-cycle. When the first energy storage unit 121 is about to run out of power, the second energy storage unit 123, which initially has a low charge level, then continues to charge the image capture device 200.

[0072] When the external charger 300 is electrically connected to the second interface 50, the external charger 300 outputs a second charging current. The first charge / discharge management chip 1221 adjusts the second charging current based on the first charging power to obtain and output a first target current to charge the first energy storage unit 121. As the real-time charge of the first energy storage unit 121 increases, when the real-time charge of the first energy storage unit 121 reaches the rated charge, the second charge / discharge management chip 1222 receives the second charging current and adjusts it based on the second charging power to obtain and output a second target current to charge the second energy storage unit 123.

[0073] Therefore, when the external charger 300 charges the first energy storage unit 121 or the second energy storage unit 123, the first energy storage unit 121 with a high original charge is charged first, and the second energy storage unit 123 with a low original charge is charged only after the first energy storage unit 121 is fully charged.

[0074] Please see Figure 8 , Figure 8 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 8 As shown, the charge / discharge management unit 122 includes a third charge / discharge management chip 1223 and a boost chip 1224. The first end of the third charge / discharge management chip 1223 is connected to the second node b point together with the first energy storage unit 121 and the second energy storage unit 123. The second end of the third charge / discharge management chip 1223 is connected to the second interface 50. The third charge / discharge management chip 1223 is also connected to the controller 13.

[0075] When the external charger 300 is electrically connected to the second interface 50, the controller 13 sends a first charging power to the third charge / discharge management chip 1223. Based on the first charging power, the third charge / discharge management chip 1223 adjusts the second charging current output by the external charger 300 to obtain and output a first target current to charge the first energy storage unit 121. Similarly, when the real-time charge level of the first energy storage unit 121 reaches the rated charge level, the controller 13 sends a second charging power to the third charge / discharge management chip 1223. Based on the second charging power, the third charge / discharge management chip 1223 adjusts the second charging current output by the external charger 300 to obtain and output a second target current to charge the second energy storage unit 123.

[0076] In related technologies, the number of energy storage units and charge / discharge management chips are usually corresponding. In this embodiment, one charge / discharge management chip is used to charge the first energy storage unit 121 and the second energy storage unit 123 respectively, saving one charge / discharge management chip and reducing circuit costs.

[0077] The boost chip 1224 is connected between the second node b and the first interface 30. When the image capture device 200 is electrically connected to the first interface 30, the boost chip 1224 boosts the first voltage output from the first energy storage unit 121 to obtain and output a second voltage to charge the image capture device 200. When the energy in the first energy storage unit 121 is about to be depleted, the boost chip 1224 boosts the third voltage output from the second energy storage unit 123 to obtain and output a fourth voltage to charge the image capture device 200.

[0078] In this embodiment, a boost chip 1224 is used to boost the first voltage output from the first energy storage unit 121 and the third voltage output from the second energy storage unit 123, respectively. Compared with the one-to-one configuration of each energy storage unit corresponding to a boost chip in related technologies, this saves one boost chip and reduces circuit costs. In this embodiment, the boost chip 1224 is a BOOST boost IC.

[0079] It should be noted that the models of the first charge / discharge management chip 1221, the second charge / discharge management chip 1222, the third charge / discharge management chip 1223, and the boost chip 1224 can be set as needed. The first charge / discharge management chip 1221, the second charge / discharge management chip 1222, and the third charge / discharge management chip 1223 can be the same model of chip or different models of chip.

[0080] Please see Figure 9 , Figure 9 This is a structural schematic diagram of a support device provided in an embodiment of this utility model, as shown below. Figure 9As shown, the charge and discharge management unit 122 also includes a second switch unit 1225 and a third switch unit 1226, wherein the second switch unit 1225 is connected between the second node b and the first energy storage unit 121, and the third switch unit 1226 is connected between the second node b and the second energy storage unit 123.

[0081] The control terminal of the second switching unit 1225 is also connected to the controller 13, and the control terminal of the third switching unit 1226 is also connected to the controller 13. The controller 13 sends corresponding second control signals and third control signals to the second switching unit 1225 and the third switching unit 1226, respectively. The second control signal controls the second switching unit 1225 to turn on or off, so as to control the connection state between the second node b and the first energy storage unit 121. The third control signal controls the third switching unit 1226 to turn on or off, so as to control the connection state between the second node b and the second energy storage unit 123.

[0082] When the first energy storage unit 121 charges the image capture device 200, or when the external charger 300 charges the first energy storage unit 121, the controller 13 controls the second switch unit 1225 to be in the conducting state via the second control signal, and the second node b is connected to the first energy storage unit 121. Furthermore, the controller controls the third switch unit 1226 to be in the off state via the third control signal, and the second node b is disconnected from the second energy storage unit 123 to prevent charging self-circulation.

[0083] When the second energy storage unit 123 charges the image capture device 200, or when the external charger 300 charges the second energy storage unit 123, the controller 13 controls the third switch unit 1226 to be in the conducting state via the third control signal, and the second node b is connected to the second energy storage unit 123. Furthermore, the controller controls the second switch unit 1225 to be in the off state via the second control signal, and the second node b is disconnected from the first energy storage unit 121 to prevent charging self-circulation.

[0084] Therefore, by controlling the connection state between the second node b and the first energy storage unit 121 through the second switch unit 1225, and controlling the connection state between the second node b and the second energy storage unit 123 through the third switch unit 1226, the phenomenon of charging self-circulation can be prevented, and the accuracy and efficiency of charging can be improved.

[0085] In some embodiments, please continue reading Figure 9 The charge and discharge management unit 122 also includes a fourth switch unit 1227, which is connected between the boost chip 1224 and the first interface 30. The control terminal of the fourth switch unit 1227 is connected to the controller 13.

[0086] The controller 13 sends a fourth control signal to the fourth switch unit 1227. The fourth control signal controls the fourth switch unit 1227 to turn on or off, thereby controlling the connection status between the boost chip 1224 and the first interface 30.

[0087] When the first energy storage unit 121 charges the image capture device 200, or the second energy storage unit 123 charges the image capture device 200, the controller 13 controls the fourth switch unit 1227 to be in the conducting state through the fourth control signal, and the boost chip 1224 establishes a connection with the first interface 30, so that the second voltage or the fourth voltage can be output to the image capture device 200.

[0088] When the external charger 300 is electrically connected to the second interface 50, the controller 13 controls the fourth switch unit 1227 to be in the off state through the fourth control signal, and the boost chip 1224 is disconnected from the first interface 30. Then, the first charging current is transmitted to the image capture device 200, and the second charging current is output to the first energy storage unit 121 or the second energy storage unit 123. The fourth switch unit 1227 is in the off state, which can prevent the first charging current from flowing back to the first energy storage unit 121 or the second energy storage unit 123, so as to replenish the image capture device 200 with power in time, reduce the charging interference between the first energy storage unit 121 or the second energy storage unit 123 and the image capture device 200, and improve the charging stability.

[0089] It should be noted that the second switching unit 1225, the third switching unit 1226, and the fourth switching unit 1227 are all switching transistors such as transistors, MOSFETs, and thyristors.

[0090] In summary, when the image capture device is mounted on the bracket device, the first interface is electrically connected to the image capture device, and the power supply circuit charges the image capture device through the first interface. Therefore, when the image capture device is mounted on the bracket device, the bracket device can charge the image capture device without the need for a socket or connecting cable, improving the flexibility and stability of charging the image capture device.
