DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] refer to Figures 1 to 6 :

[0024] The utility model provides a portable ground battery 4 box, which can be connected to most links of a drone and switch power without delay, including a box body 1, a power switch 2, and a display screen 3. A 12S lithium battery 4 is arranged on the inner side of the box body 1, and a power switch 2 and a display screen 3 are arranged on the side of the box body 1. The box body 1 also includes a heat dissipation fin 5, an electric plug 6, a heat dissipation fan 7, and a power management module 8. A partition 9 is arranged on the inner cavity of the box body 1, and the partition 9 divides the inner cavity of the box body 1 into a battery compartment 10 and a function compartment 11. The battery 4 is installed in the battery compartment 10, and the heat dissipation fin 5 and the power management module 8 are installed in the function compartment 11. The heat dissipation fan 7 is installed on the box body 1 near one side of the function compartment 11. The box body 1 is also provided with a heat dissipation hole 12 on the other side corresponding to the heat dissipation fan 7. The electric plug 6 is installed on the box body 1 near the display screen 3. On the side, all components of the ground battery 4 box are installed inside the box body 1 or fixed on the side wall of the box body 1, the 12S lithium battery 4 is connected in series to the power management module 8 by wires, and the power management module 8 is connected to the multi-function power supply and discharge plug 6 and fixed on the box body 1, the power management module 8 is cooled by the heat dissipation fins 5, the cooling fan 7 and the display screen 3 are connected to the power management module 8 by the power supply line and powered by it, the multi-function power supply and discharge plug 6 can simultaneously power the XT-30\XT-90 connector, a single ground battery 4 box can power most electrical systems on the drone, such as flight control, motor, and electric speed controller, and has an uninterrupted power switching function after the drone test state is switched, to ensure that the operating state of the drone link is consistent in the two states, the ground battery 4 box is a closed installation method, and all components are fixed to the box body 1 with fixing bolts after installation.

[0025] Here, the main storage and discharge devices of the battery box 4 are two 12S lithium batteries 4, which are connected in series through a power cord to the transformer circuit board and then to the multi-function power supply and discharge plug 6. The plug supplies power to the energy storage lithium battery 4 and the drone electronic equipment. On the left side of the plug is a liquid crystal display 3, which can clearly display information such as the voltage of the energy storage lithium battery 4, the interface input and output voltage, so that the user can clearly understand the current device status of the battery box 4.

[0026] The present invention also includes a positioning module 13 and a heating module 14. The positioning module 13 is installed on one side of the functional compartment 11 near the power management module 8. The heating module 14 is installed on the inner wall of the box body 1 in the battery 4 installation mold area, and is used to heat and keep the battery 4 warm in extremely cold weather. The heating module 14 is arranged on the side wall of the box body 1, and the distance from the battery 4 is 10-20mm. For example, a PTC heating sheet can be used. In order to prevent the overheating from scalding the battery 4, a thin sheet heat insulation cover can be arranged between the heating module 14 and the battery 4 to isolate the battery 4. In order to dissipate some heat, the ground battery 4 box has both heating and heat dissipation devices. In the heat dissipation device, the cooling fan 7 and the heat dissipation holes 12 form convection to take away the heat from the heat dissipation fins 5. At the same time, because the heat resistance temperature of nylon PA66 is about 60-70°C, the temperature of the heating plate inside the ground battery 4 box is not more than 50°C, so it can be ensured that the ground battery 4 box can still work under the outdoor temperature of -20°C to 30°C, ensuring that a single ground power box can meet most of the power needs of the drone and reduce the pressure on the maintenance personnel.

[0027] Specifically, UAV testing and flight environments are often carried out in the field. The ground battery box 4 needs to be temporarily placed in an unmarked place for various reasons. At this time, the Beidou positioning system is needed to assist maintenance personnel in finding the ground battery box 4. This design uses the TOPGNSS series high-precision GNSS RTK positioning and orientation module board with a positioning accuracy of less than 5m.

[0028] A wiring hole 15 is provided on one side of the partition plate 9 for wiring.

[0029] It also includes a second partition 169, which is arranged in the box body 1 and on the other side of the partition 9, wherein the second partition 169 divides the battery compartment 10 into a first battery compartment 17 and a second battery compartment 18, and the two batteries 4 are stored in the first battery compartment 17 and the second battery compartment 18 respectively.

[0030] The outer side of the box body 1 is also provided with a shape slot 19 , and the shape slot 19 includes a corner slot 191 and a middle slot 192 . The corner slot 191 is located at the four corner positions of the box body 1 , and the middle slot 192 is located at the outer side of the partition 9 .

[0031] The box body 1 further comprises a box cover 20, which is detachably fixedly connected to the box body 1 by bolts.

[0032] The battery 4 is a 12S lithium battery 4, the electric plug 6 is a multifunctional power supply and discharge plug 6, the box body 1 is made of nylon PA66 with a density of 1.15g / cm3, and is preferably made by 3D printing, the positioning module 13 is a Beidou locator, and the power management module 8 is an AD / AD circuit board

[0033] Specifically, the box body 1 and the box cover 20 are made of nylon PA66 and are fixed by fixing bolts to ensure their low cost and light weight while the strength can meet the use requirements. All equipment is fixed on the box body 1, which can provide a maximum voltage of 48V for the drone electronic system without a fixed power supply, a stable power supply, and connect a multi-function plug through the power management module 8 to adapt to the drone power requirements of different voltages, XT-30\XT-90 and other different types of plugs. At the same time, when the drone is changing its state, the ground battery 4 box can ensure that the drone link is converted without intervals, ensuring the stability of the drone link state.

[0034] Specifically, when this battery box 4 is in use, when the onboard link and flight control of the large unmanned aerial vehicle are changing between the test and flight states, in order to ensure that the aircraft state is consistent in the two states, the power is generally restarted. At this time, the ground power supply and the onboard power supply need to be switched uninterruptedly. The power management module 8 of this ground battery box 4 has a voltage-stabilized power supply switching module, which has automatic switching of DC12V-48V voltage.

[0035] Specifically, when in use, the battery box can be connected to a corresponding battery box frame by means of the shape slot 19 on the box body, or connected to the battery box mounting position on the drone, and plugged therein, which is very convenient to use.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
