Detailed Implementation

[0037] The following will describe the concept, specific structure and technical effects of this utility model clearly and completely with reference to the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0038] Various embodiments of the present invention will be described more fully below. The present invention may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present invention to the specific embodiments disclosed herein, but rather the present invention should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of the present invention.

[0039] See Figure 1-2 As shown, this application provides a power adapter and a power system having the same, the specific solution of which is as follows:

[0040] In a first aspect, a power conversion device is proposed, the conversion device comprising: a conversion body 1 and at least one conversion plate 2.

[0041] The adapter 1 has a power interface 11 and at least one battery mounting position 12 on its surface, and the battery mounting position 12 is electrically connected to the power interface 11. The adapter plate 2 has an output terminal 3 on one side and an input terminal 4 on the other side. The output terminal 3 can be electrically connected to the power device 7 or the adapter 1; the input terminal 4 can be electrically connected to a spare battery 5. The adapter 1 is as follows... Figure 12 As shown, the overall structure is compact, lightweight and easy to carry. By connecting the spare battery 5 to the adapter 1, the spare battery 5 can be centrally stored, avoiding forgetting to bring the spare battery 5 or scattering the spare battery 5 in various devices.

[0042] like Figure 15 As shown, the adapter board 2 is provided with a voltage conversion circuit board 23. The voltage conversion circuit board 23 is used to adjust the voltage value of the output terminal 3 so as to convert the electrical energy of the backup battery 5 and transmit it to the adapter body 1 or the electrical device 7.

[0043] It should be noted that this embodiment does not specifically limit the specific location and number of battery mounting positions 12 on the adapter body 1. As long as it is possible to connect the battery mounting position 12 of the adapter body 1 to the spare battery 5 through the adapter plate 2, and the spare battery 5 will not affect each other when installed in the battery mounting position 12, multiple battery mounting positions 12 can be provided on the adapter body 1.

[0044] In some alternative embodiments, such as Figure 5 , Figure 7 and Figure 10As shown, at least one side of the adapter plate 2 is provided with a quick-release structure 61. The quick-release structure 61 is used for detachable connection with the electrical device 7, or the battery mounting position 12, or the spare battery 5; the quick-release structure 61 includes a snap-fit ​​block 62, and / or a snap-fit ​​groove 63, and / or a movable buckle. By providing a quick-release structure 61 on at least one side of the adapter plate 2, the mechanical connection between the adapter plate 2 and different components can be made more accurate. When the adapter plate 2 and the component are provided with corresponding shapes, the user can visually match the adapter plate 2 and the component.

[0045] It should be noted that this embodiment does not specifically limit the location or shape of the quick-release structure 61. In practical applications, users can set the shape of the quick-release structure 61 according to the different external features of the connected components.

[0046] In some optional embodiments, the adapter plate 2 includes a first adapter plate 21; the backup battery 5 includes a first backup battery 51; the output terminal 3 of the first adapter plate 21 is provided with a quick-release structure 61 for connecting the electrical device 7. The quick-release structure 61 is used to connect the electrical device 7 or to alternately connect the electrical device 7 and the battery mounting position 61. The input terminal 4 of the first adapter plate 21 is provided with a contact pin 64, and the first adapter plate 21 is used to connect the first backup battery 51 through the contact pin 64 to convert the electrical energy of the first backup battery 51 and transmit it to the electrical device 7. In a specific usage scenario, the user connects the input terminal 4 of the first adapter board 21 to the first backup battery 51. Furthermore, the user connects the output terminal 3 of the first adapter board 21 to the device 7 via the quick-release structure 61. This establishes an electrical connection between the first backup battery 51 and the device 7, allowing the first backup battery 51 to power the device 7. Figure 3 As shown, the electrical device 7 is a supplementary light. When the model of the first backup battery 51 is not compatible with the electrical device 7, the first adapter board 2 can be used to convert the power supply interface of the first backup battery 5 to make it compatible with the electrical device 7, so as to realize the power supply for different models of electrical devices 7.

[0047] In some optional embodiments, there may be multiple types of first adapter plates 21. Different quick-release structures 61 may be provided on the surface of different types of first adapter plates 21 and second adapter plates 22. Different quick-release structures 61 can be used with different electrical devices 7, and can also be connected with different battery mounting positions 12 of the adapter body 1.

[0048] In a specific application, the first adapter plate 21 and the second adapter plate 22 can be adapter plates 2 that can be used with different electrical devices 7. In actual operation, there are often multiple types of electrical devices 7 that need to be powered. When the electrical device 7 changes from one that matches the quick-release structure 61 of the first adapter plate 21 to one that matches the quick-release structure 61 of the second adapter plate 22, the user can remove the first adapter plate 21 from the electrical device 7, remove the second adapter plate 22 from the battery mounting position 12 of the adapter body 1, and then directly connect the quick-release structure 61 of the second adapter plate 22 to the electrical device 7, and connect the quick-release structure 61 of the first adapter plate 21 to the battery mounting position 21 of the adapter body 1, thus realizing the replacement of the adapter plate 2 for connecting the electrical device 7. This configuration allows for more diverse connection schemes between the adapter body 1, the adapter plate 2, and the electrical device 7, effectively adapting to the diverse connection needs of devices in actual applications.

[0049] In some alternative embodiments, such as Figure 2 As shown, the adapter plate 2 further includes a second adapter plate 22; the backup battery 5 further includes a second backup battery 52. ​​The output terminal 3 of the second adapter plate 22 is provided with a quick-release structure 61 for connecting to the battery mounting position 12, and the input terminal 4 of the second adapter plate 22 is provided with a contact pin 64. The second adapter plate 22 connects to the second backup battery 52 via the contact pin 64 to convert the electrical energy of the second backup battery 52 and output it to the power interface 11 of the adapter body 1. In one specific embodiment, quick-release structures 61 are provided on both sides of the second adapter plate 22, enabling a stable mechanically detachable connection between the backup battery 5, the second adapter plate 22, and the battery mounting position 12.

[0050] In one specific embodiment, such as Figure 2 As shown, the first adapter board 21 is also provided with a power cable 212 on the input terminal 4, one end of which is connected to the power interface 11. The first adapter board 21 is electrically connected to the power interface 11 through the power cable 212.

[0051] When a spare battery 5 is installed on the battery mounting position 12 of the adapter body 1, the first adapter plate 2 can be electrically connected to the power interface 11 of the adapter body 1 by setting the power cable 212. This allows the electrical device 7 to connect to the second spare battery 52 through the path of the first adapter plate 21-power cable 212-power interface 11-adapter body 1-battery mounting position 12-second adapter plate 22, and obtain power from the second spare battery 52.

[0052] The first adapter plate 21 has multiple uses. In a specific application, when one side of the first adapter plate 21 is connected to the electrical equipment 7 and the other side is connected to the adapter body 1, the other side can also be connected to the first backup battery 51, such as... Figure 2 As shown, the user can choose between the first backup battery 51 and the second backup battery 52 on the adapter 1 to achieve multiple charging schemes. When the first backup battery 51 is connected to the first adapter plate 21 and the second backup battery 52 is connected to the second adapter plate 2 connected to the adapter 1, the user can choose to power the device 7 through the first backup battery 51 or through the second backup battery 52 according to actual needs.

[0053] It should be noted that this embodiment does not specify the specific model of the backup battery 5. In practical applications, the first backup battery 51 and the second backup battery 52 can be the same or different models. The adapter in this embodiment is precisely capable of realizing the power conversion and power supply connection between different models of batteries and different models of electrical equipment 7. Users can select the required backup battery 5 according to their actual needs.

[0054] Furthermore, such as Figure 1 , Figure 13 and Figure 14 As shown, the first backup battery can be omitted, and a power cable 212 connecting to the adapter body 1 can be provided at the input terminal 4 of the adapter plate 2. This allows the adapter plate 2 to be connected to the adapter body 1 only through the power cable 212 at the input terminal 4, and to obtain power from the second backup battery 52 from the adapter body 1. In this case, the quick-release structure 61 and contact pin 64 for connecting the first backup battery 51 can be omitted at the input terminal 4 of the adapter plate 2.

[0055] In some optional embodiments, a connector 211 is provided on the input electrical terminal 4 of the first adapter plate 21; one end of the power cord 212 is fixedly or detachably connected to the first adapter plate 21 via the connector 211. In one specific embodiment, the power cord 212 is detachably connected to the connector 211 of the first adapter plate 2, which allows the user to store the power cord 212 separately when the first adapter plate 2 is not needed to connect to the adapter body 1.

[0056] In some optional embodiments, a logic circuit board is provided within the first adapter board 21 and / or the second adapter board 22; the logic circuit board includes a control chip, a comparison circuit, a detection circuit, and a power switching circuit interconnected with each other. The detection circuit is used to detect the charge values ​​of the first backup battery 51 and the second backup battery 52 respectively; the comparison circuit is used to compare the charge values; the power switching circuit switches between being powered by the first backup battery 51 or the second backup battery 52 according to the comparison result of the comparison circuit.

[0057] In some optional embodiments, the adapter 1 includes a power management circuit, which is electrically connected to the power interface 11 and the battery mounting position 12. In practical applications, the power management circuit is a dual MOSFET power switching circuit.

[0058] In some optional embodiments, the adapter further includes a battery pack containing multiple removable spare batteries 5. The battery pack is equipped with an electrical connection structure and a locking structure 65 that mates with the input terminal 4. In practical applications, the battery pack is a universal battery pack, allowing users to place or replace different numbers and types of batteries according to their actual needs.

[0059] In an optional embodiment, the battery pack can be adapted to batteries of different specifications such as 2S, 4S, or 6S. When the battery specifications in the battery pack do not match the model of the power device 7, by configuring an adapter board 2 with different interfaces and performing voltage boosting or bucking through the voltage conversion circuit inside the adapter board 2, it is possible to enable batteries of different specifications to output the power required by the power device 7. This is suitable for a variety of practical application scenarios, effectively solves the power supply problem of the power device 7, and ensures the smooth progress of shooting.

[0060] It should be noted that in a usage scenario with a first adapter plate 21 and a second adapter plate 22, and the first adapter plate 21 connected to the adapter body 1, the user can supply power to the electrical device 7 in multiple ways. For example, when the first adapter plate 21 is directly connected to the first backup battery 51, and the second adapter plate 22 on the battery mounting position 12 is connected to the second backup battery 52, the user can choose to supply power to the electrical device 7 through the first backup battery 51 or through the second backup battery 52.

[0061] In a specific application scenario, the detection circuit in the logic circuit board of the first adapter board 2 and / or the second adapter board 2 can detect the remaining power in the first backup battery 51 and the second backup battery 52, as well as the current and voltage status in the adapter body 1. The comparison circuit can further compare the remaining power of the first backup battery 51 and the second backup battery 52. ​​The control chip can send a signal to the power switching circuit according to the comparison result obtained by the comparison circuit to adjust the power supply to the device 7 via the first backup battery 51 or the second backup battery 52. ​​In practical applications, the control chip can set the order of power supply via the first backup battery 51 or the second backup battery 52. ​​For example, the device 7 can be powered by the first backup battery 51 first, and when the power of the first backup battery 51 is exhausted or drops to a preset value, the power supply can be switched to the second backup battery 52.

[0062] It should be noted that since this embodiment does not specifically limit the number of battery mounting positions 12 on the adapter 1, the user can install the second backup battery 52 on multiple battery mounting positions 12. There can be multiple second backup batteries 52. Furthermore, when there are multiple second backup batteries 52, the power supply sequence between the multiple second backup batteries 52 can be adjusted by the control chip.

[0063] In some optional embodiments, the output terminal 3 and / or the input terminal 4 of the adapter board 2 include: a V-port, and / or an A-port, and / or a D-TAP interface, and / or a customized interface. By setting different input terminals 4 and output terminals 3, power can be supplied from batteries of different specifications to devices of different specifications. Among them, an adapter board adapted to V-port batteries is as follows: Figure 4 , Figure 5 , Figure 6 As shown.

[0064] In the field of photography, different camera and equipment brands may develop proprietary transmission or power supply interfaces, making them incompatible. However, by providing multiple brand-specific interfaces on adapter board 2, cross-brand compatibility during charging and data transfer can be achieved. The V-mount is a lithium-ion battery interface standard used for quick installation and stable power supply to devices and batteries, suitable for mainstream lighting equipment, monitors, stabilizers, and professional cameras. The A-mount is a dedicated battery interface standard for photographic equipment and a mainstream power supply interface. The D-TAP interface is a power supply interface suitable for high-power lighting equipment, follow focus systems, and wireless image transmission devices.

[0065] In a specific application, the battery pack contains multiple backup batteries, specifically 4S batteries. Figure 10 and Figure 11 As shown, the output terminal 3 of the adapter board 2 needs to be connected to an X100 camera that is compatible with 6S batteries. The required battery voltage is approximately 21V, while the battery voltage of the 4S battery in the battery pack is only 14.8V, which cannot directly meet the power supply requirements. In this case, the voltage conversion circuit in the adapter board 2 can boost the voltage of the 4S battery and then output it to the X100 device through a customized interface. This enables the 4S battery to power the standard 6S battery device.

[0066] In another specific application process, such as Figure 7 and Figure 8 As shown, the output terminal 3 of the adapter board 2 is equipped with a snap-fit ​​block 62 and a snap-fit ​​groove 63 that are compatible with the battery port of the F970 camera. The F970 battery that is compatible with the F970 camera is a 2S battery. It can be understood that the output voltage of the 4S battery in the battery pack can directly meet the power supply requirements at this time. Therefore, the voltage conversion circuit in the adapter board 2 can step down the voltage of the 4S battery to achieve the 7.4V of the 2S battery, so as to realize the power supply of the 4S battery to the standard equipment of the 2S battery.

[0067] In a specific application, a locking structure 65 can also be provided on the surface of the adapter plate 2. The locking structure 65 can be a movable buckle controlled by a knob. The user can control the tightness of the connection between the adapter plate 2 and other components by rotating the knob.

[0068] When the device 7 connected to the adapter board 2 is a V-port dedicated device, the power supply voltage of the 4S battery in the battery pack can be directly adapted to the V-port dedicated device. In this case, there is no need for the adapter board 2 to convert the power supply voltage, and it can directly supply power to the device 7. This is suitable for applications that only require interface conversion.

[0069] In some alternative embodiments, the power interface 11 includes a 3-pin connector output interface, and / or a USB-C interface, and / or a DC interface. By providing multiple different power interfaces 11, more different models of devices can be connected to the adapter 1.

[0070] In some optional embodiments, a heat dissipation structure 13 is provided on at least one side of the adapter 1. In a specific usage process, since backup batteries 5 are connected to the battery mounting positions 12 of the adapter 1, heat may be generated at the adapter 1 during the conversion and transmission of electrical energy, reducing the efficiency of power transmission. By providing the heat dissipation structure 13, the heat at the adapter 1 can be effectively transferred to the outside, ensuring the stable operation of the adapter 1. It should be noted that this embodiment does not specifically limit the specific shape and structure of the heat dissipation structure 13; the heat dissipation structure 13 can be a heat dissipation strip-shaped hole, such as... Figure 1 As shown.

[0071] Secondly, a power supply system is proposed, which has any of the power adapters in the aforementioned technical solutions, and can be adapted to various types of batteries to stably provide power to various electrical devices such as cameras, video cameras, and lighting equipment, thereby effectively improving the efficiency of shooting operations.

[0072] This embodiment provides a power adapter and a power system incorporating it. The power adapter includes an adapter body and at least one adapter plate. The adapter body has a power interface and at least one battery mounting position on its surface, with the battery mounting position electrically connected to the power interface. One side of the adapter plate has an output terminal, and the other side has an input terminal. The output terminal can be electrically connected to a power-consuming device or the adapter body; the input terminal can be electrically connected to a backup battery. The adapter plate contains a voltage conversion circuit board for adjusting the voltage value of the output terminal, enabling the conversion and transmission of power from the backup battery to the adapter body or the power-consuming device. This is suitable for situations with various types of power-consuming devices and different types of backup batteries, allowing for the unified conversion and transmission of power from different specifications of backup batteries to the power-consuming devices, providing sufficient power for their operation. The power system incorporating this adapter can stably provide power to the power-consuming devices using various types of batteries, ensuring the smooth operation of filming.
