That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0031] It should be noted that the term "plurality" used in this document refers to two or more. "And / or" describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. The character " / " generally indicates an "or" relationship between the associated objects.

[0032] In recent years, with the development of the photography industry, cameras have increasingly required an increasing number of auxiliary devices during use, such as mobile phones, photographic lighting, monitors, follow focus devices, wireless image transmission systems, stabilizers, microphones, and more. Since these devices require power, and to achieve the multi-purpose functionality of photographic batteries, photographic batteries can be equipped with a variety of power ports to power external auxiliary devices. For example, in addition to conventional D-Tap and V-mount ports, these batteries may also be equipped with USB-A, Type-C, and DC ports. In this context, since photographic batteries may need to power multiple types of devices, effective control of these ports to ensure safety and power efficiency is a pressing technical issue.

[0033] Based on the above technical problems, the present invention proposes a new battery for photography. Figure 1 As shown, the photographic battery in the embodiment of the present application includes: a battery module 100 , a first port module 200 , a second port module 300 and a Bluetooth module 400 .

[0034] Among them, the battery module 100 includes a battery pack for storing electrical energy; the first port module 200 is electrically connected to the battery module 100, and the first port module 200 is used to enable the battery pack to supply power to the photographic equipment.

The Bluetooth module 400 is electrically connected to the battery module 100 and can communicate with a battery control terminal to receive control signals for the controllable port. Optionally, the battery control terminal may include, for example, a smartphone, tablet computer, or desktop computer.

The voltage conversion circuit 301 is electrically connected to the battery module 100 and is used to convert the output voltage of the battery pack; the anti-reverse connection circuit 302 is connected between the voltage conversion circuit 301 and the DC output port 303 to prevent the DC output port 303 from transmitting voltage to the voltage conversion circuit 301; and the DC output port 303 is used to connect to an external device.

[0037] exist Figure 2 In the illustrated embodiment, the provision of a reverse polarity protection circuit 302 ensures that only the battery module 100 can supply power to external devices via the DC output port 303. This prevents a user from mistakenly connecting the DC output port 303 to a power source, whereby the power voltage is reversely applied to the battery module 100 via the DC output port, potentially damaging the camera battery. Optionally, the external device may include a mobile phone, a camera, a photographic light, a laptop, a monitor, a focus controller, a wireless image transmitter, a stabilizer, a microphone, or the like. In a specific implementation, the reverse polarity protection circuit 302 may be a unidirectional switching device, such as a diode.

[0038] In some optional embodiments, if the second port module 300 includes at least two DC output ports 303 and voltage conversion circuits 301 corresponding to the at least two DC output ports 303, then the at least two DC output ports 303 can be connected to different anti-reverse connection circuits 302, and different anti-reverse connection circuits 303 are connected to different voltage conversion circuits 301. That is, the embodiment of the present application can have multiple Figure 2 The circuit structure of the voltage conversion circuit 301, the anti-reverse connection circuit 302 and the DC output port 303 shown in FIG.

[0039] In some optional embodiments, referring to Figure 3As shown, the battery module 100 includes, in addition to the battery pack 101, a BMS (Battery Management System) module 102 and a main control circuit 103. The BMS module 102 is electrically connected to the battery pack 101, the main control circuit 103 is electrically connected to the BMS module 102, and the voltage conversion circuit 301 is electrically connected to the BMS module 102 and the main control circuit 103. The DC output port 303 can also be communicatively connected to the main control circuit 103 to provide feedback of port status information to the main control circuit 103.

[0040] Optionally, the BMS module 102 can provide monitoring and protection for the battery pack 101 during its charge and discharge process, such as temperature monitoring, voltage monitoring, current monitoring, overcurrent protection, over-temperature protection, short-circuit protection, undervoltage protection, and overvoltage protection. This prevents abnormal conditions from occurring during the charge and discharge process and adversely affecting the performance of the battery pack 101, thereby extending its service life. The port status information fed back by the DC output port 303 to the main control circuit 103 may include, for example, one or more parameters such as current, voltage, and power.

[0041] In some optional embodiments, referring to Figure 4 As shown, the second port module 300 may include a voltage conversion circuit 304, a USB-A protocol module 305, and a USB-A port 306.

Optionally, the USB-A port 306 can also be used to charge the battery pack in the battery module 100. If the second port module 300 includes multiple USB-A ports 306, then these multiple USB-A ports 306 can be connected to the same USB-A protocol module 305 or to different USB-A protocol modules 305. In other words, if the second port module 300 includes multiple USB-A ports 306, then the output voltages of these multiple USB-A ports 306 when supplying power to the outside can be the same or different.

[0043] Optionally, the USB-A protocol module 305 is used to manage and process digital signals from external devices connected to the USB-A port 306, and the voltage conversion circuit 304 is used to transform the output voltage of the battery module 100 to a target output voltage and output the target output voltage to the USB-A port 306. After the USB-A port 306 is connected to an external device, the USB-A protocol module 305 converts the electrical signals from the USB-A port 306 into digital signals that can be recognized and processed by a computer or other device, parses and processes the USB communication protocol, ensures normal data transmission and communication flow between devices, monitors errors during the data transmission process, corrects them when possible, or provides error feedback, and ensures that the data transmission rate meets the negotiation between the device and the host to achieve optimal transmission efficiency.

[0044] In some optional embodiments, referring to Figure 5 As shown, in addition to the battery pack 101, the battery module 100 may also include a BMS module 102 and a main control circuit 103. The BMS module 102 is electrically connected to the battery pack 101, the main control circuit 103 is electrically connected to the BMS module 102, and the voltage conversion circuit 304 is electrically connected to the BMS module 102 and the main control circuit 103. The USB-A port 306 can also be communicatively connected to the main control circuit 103 to feedback port status information to the main control circuit 103. Optionally, the port status information fed back by the USB-A port 306 to the main control circuit 103 may include one or more parameters such as current, voltage, and power.

[0045] In some optional embodiments, referring to Figure 6 As shown, the second port module 300 may include: a power processor 307, a voltage conversion circuit 308, and a Type-C port 309. The Type-C port 309 is used to connect to an external device or a charging power source; the voltage conversion circuit 308 is electrically connected to the Type-C port 309; and the power processor 307 is connected between the battery module 100 and the voltage conversion circuit 308 to implement charge and discharge control of the Type-C port 309. Optionally, the power processor 307 can identify whether to supply power to an external device or charge the battery module 100, thereby enabling charge and discharge control of the Type-C port 309.

[0046] Optionally, the Type-C port 309 can be communicatively connected to the power processor 307 to feed back port status information (such as one or more parameters such as current, voltage, power, etc.) to the power processor 307.

[0047] Optionally, the Type-C port 309 can be connected to an Emark identification module, which is electrically connected to the power processor 307. In this case, the Emark identification module can detect and identify the external device connected to the Type-C port 309 and determine its power requirements. The power processor 307 then identifies and confirms the external device based on the Emark identification module and controls the voltage conversion circuit 308 to output the corresponding voltage.

[0048] In some optional embodiments, a display module may be further provided on the photographic battery. The display module is electrically connected to the battery module 100 and is used to present a battery control interface corresponding to the photographic battery.

[0049] Optionally, the battery control interface corresponding to the photographic battery may display one or more of the following information: the remaining battery power of the photographic battery, the remaining discharge time of the photographic battery, the temperature of the photographic battery, the attribute information of each port of the photographic battery (such as the type of each port, etc.), the power supply status of each port of the photographic battery, the abnormal alarm information of the photographic battery, the controls corresponding to each port of the photographic battery (the external power supply function of the port can be turned off or the external output power of the port can be adjusted through the control), the switch control of the photographic battery (the external power supply function of the photographic battery can be turned on or off through the switch control), the status information display mode switching control (the display mode of the battery control interface can be adjusted through the switching control, such as the display color, interface layout, etc.), the health status of the photographic battery, the number of times the photographic battery is charged, the number of times the photographic battery is discharged, the remaining life of the photographic battery, the charging threshold of the photographic battery, the discharge threshold of the photographic battery, etc.

[0050] In some optional embodiments, a key module may also be provided on the photographic battery, which is electrically connected to the battery module 100; wherein the key module is used to turn on or off the display module; and / or the key module is used to turn on or off the external power supply of the photographic battery.

[0051] It should be noted that the above embodiments can be implemented separately or in combination. For example, in the embodiment of the present application, the second port module 300 can include one or more ports in the above embodiments, and the number of each port can be one or more. Specifically, in one embodiment of the present application, Figure 7 As shown, the first port module 200 of the photographic battery may include a D-Tap input and output port and a V-port input and output port; the second port module 300 may include: a DC12V output port, a DC8V output port, a USB-A output port, a Type-C port 1, and a Type-C port 2. It should be noted that Figure 7The ports shown in the figure are only examples. In implementation, any type and any number of ports can be set according to actual needs, and the output voltage of the port can be set according to actual needs.

[0052] Continue to refer to Figure 7 As shown, the DC12V voltage conversion circuit is connected to the DC12V output port via a reverse polarity protection circuit, and the DC8V voltage conversion circuit is connected to the DC8V output port via a reverse polarity protection circuit. Because a reverse polarity protection circuit is provided between the DC8V output port and the DC8V voltage conversion circuit, and between the DC12V output port and the DC12V voltage conversion circuit, power is ensured to the DC output port and external load only when the correct polarity is present. If the user incorrectly connects the power adapter, the reverse polarity protection circuit will prevent power from passing through, protecting the device and power supply from damage, thereby improving the safety of photographic batteries.

[0053] The DC12V voltage conversion circuit and the DC8V voltage conversion circuit are both connected to the main control circuit 103 and the BMS module 102. The DC8V voltage conversion circuit controls the output of 8V voltage to the DC8V output port to accommodate 8V external loads such as cameras, 8V lamps, and digital products. The DC12V voltage conversion circuit controls the output of 12V voltage to the DC12V output port to accommodate 12V external loads such as 12V lamps and digital products.

[0054] Continue to refer to Figure 7 As shown, the USB-A voltage conversion circuit is electrically connected to the main control circuit 103, the BMS module 102, and the USB-A protocol processing module, respectively, and the USB-A output port is electrically connected to the USB-A protocol processing module; the USB-A protocol processing module is used to manage and process the digital signal of the external load connected to the USB-A output port, and the USB-A voltage conversion circuit is used to transform the output voltage of the battery pack 101 to the target output voltage and output the target output voltage to the USB-A output port. After the USB-A output port is connected to the external load, the USB-A protocol processing module converts the electrical signal from the USB-A output port into a digital signal that can be recognized and processed by a computer or other device, parses and processes the USB communication protocol, ensures normal data transmission and communication process between devices, monitors errors during data transmission, corrects them as much as possible or provides error feedback, and ensures that the data transmission rate meets the negotiation between the device and the host to achieve optimal transmission efficiency.

[0055] Continue to refer to Figure 7As shown, the DC-DC power processor 1 is electrically connected to the BMS module 102, the main control circuit 103, the DC-DC voltage conversion circuit 1 and the Emark identification module respectively, and the Type-C port 1 is electrically connected to the DC-DC voltage conversion circuit 1 and the Emark identification module respectively; the DC-DC voltage conversion circuit 1 is used to transform the output voltage of the battery pack 101 to the target output voltage and output the target output voltage to the Type-C port 1, and the Emark identification module is used to detect and identify the external device connected to the Type-C port 1 and determine its power supply requirements. The DC-DC power processor 1 identifies and confirms the external device according to the Emark identification module and controls the DC-DC voltage conversion circuit 1 to output the target output voltage. Specifically, when the Type-C port 1 is connected to an external load, the Emark identification module detects and identifies the external device connected to the Type-C port 1 and determines its power supply requirements, and outputs a digital signal to the DC-DC power processor 1. After receiving the signal, the DC-DC power processor 1 transmits the control signal to the DC-DC voltage conversion circuit 1 to control the DC-DC voltage conversion circuit 1 to output the voltage required by the external device. As can be seen, the technical solution of the embodiment of the present application can automatically identify the needs of external devices and output the corresponding voltage, effectively improving the output and input functions of Type-C port 1 and realizing the fast discharge function of the Type-C port. At the same time, Type-C port 1 can not only charge devices such as mobile phones and laptops, but also charge the battery pack 101.

[0056] Optionally, refer to Figure 7 As shown, the photographic battery may also include a Type-C port 2, wherein the DC-DC power processor 2 is electrically connected to the BMS module 102, the main control circuit 103, and the DC-DC voltage conversion circuit 1, respectively, and the Type-C port 2 is electrically connected to the DC-DC voltage conversion circuit 1; the DC-DC voltage conversion circuit 2 is used to transform the output voltage of the battery pack 101 to a target output voltage and output the target output voltage to the Type-C port 2, thereby realizing the fast discharge function of the Type-C port 2. At the same time, the Type-C port 2 can not only charge devices such as mobile phones and laptops, but also charge the battery pack 101.

[0057] Continue to refer to Figure 7As shown, the D-Tap input and output ports and the V-port input and output ports are electrically connected to the BMS module 102, respectively. The D-Tap input and output ports and the V-port input and output ports are mainly used to power photographic equipment and photographic fill lights. The BMS module 102 monitors the electrical parameters of the battery pack 101 and controls the input and output of the battery pack 101 according to the electrical parameters of the battery pack 101. When the electrical parameters of the battery pack 101 are abnormal, the connection with the external load is disconnected. When the D-Tap input and output ports and the V-port input and output ports are connected to the external load, if there are no abnormalities, the BMS module 102 controls the output voltage of the battery pack 101 and outputs the output voltage to the D-Tap input and output ports and the V-port input and output ports, and supplies power to the external load through the D-Tap input and output ports and the V-port input and output ports.

[0058] Optionally, refer to Figure 7 As shown, the photographic battery may further include a display module electrically connected to the main control circuit 103 for displaying electrical parameter information of the battery pack 101 and each port. For example, the display module may display information such as the charge and discharge status of each port, as well as information such as the battery pack 101's power level, voltage, current, and power. This allows users to better manage and use the battery, avoiding power outages or battery health issues at critical moments.

[0059] Optionally, refer to Figure 7 As shown, the camera battery may further include a key module electrically connected to the main control circuit 103 and used to control the camera battery to be turned on or off, thereby allowing the user to better manage and use the battery. Optionally, the key module may also turn on or off the display module, thereby allowing the user to view or hide battery status information at any time as needed.

[0060] Optionally, refer to Figure 7 As shown, the camera battery may further include a Bluetooth module 400, which is electrically connected to the main control circuit 103 and is used to communicate with the battery control terminal. After the Bluetooth module 400 is connected to the battery control terminal, the battery control terminal can read information such as the camera battery's charge level, voltage, current, temperature, and port voltage and current status. It can also control the camera battery's on and off status and various ports, thereby enabling remote control of the camera battery.

[0061] It should be noted that the photographic battery in the embodiment of the present application may be a V-mount battery, or other types of batteries mainly used to power photographic equipment.

[0062] In a specific application scenario, refer to Figure 7As shown, assuming that the second port module includes a DC12V output port, a DC8V output port, a USB-A output port, a Type-C port 1, and a Type-C port 2, these ports and the first port module are all supplying power to the outside, and the total output power is greater than 125W (the value is only an example), then the display module of the photographic battery and / or the interface of the battery control terminal may prompt that the remaining power is insufficient and the power is about to be cut off. The power cut follows the principle of first cutting off the controllable ports and then cutting off the uncontrollable ports. For the controllable ports: the power cut begins according to the principle of cutting off the power first after the last port is inserted. If the output power is still greater than 125W after all the controllable ports are disconnected, the battery can continue to supply power. If the output current exceeds 14A (the value is only an example), the photographic battery performs overcurrent protection, and the BMS module cuts off the entire battery output. At this time, the photographic battery is completely powered off. In this case, the display module of the photographic battery can continue to display, or it can be turned off and no longer display, and can resume work after reconnecting to the device.

[0063] Assuming that the first port module does not supply power to the outside, and only the DC12V output port, DC8V output port, USB-A output port, Type-C port 1 and Type-C port 2 in the second port module are supplying power to the outside, and the total output power is greater than 110W (the value is only an example), then the display module of the photographic battery and / or the interface of the battery control terminal may prompt that the remaining power is insufficient and the power is about to be cut off. The power off follows the principle of powering off the last inserted port first, starting from the last inserted port, until the output power is less than 110W, the prompt information on the display module of the photographic battery and / or the interface of the battery control terminal disappears, and the battery operation returns to normal.

[0064] Optionally, in an embodiment of the present application, the user can also control one or more parameters of the closing, opening and output power of each port through the display module of the photographic battery and / or the interface of the battery control terminal.
