[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0027] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0029] Reference Figure 1-5 The present embodiment provides a drone battery intelligent temperature control protection module, including a drone bracket 11 and a control mainboard 5. A battery box 1 is clamped on the top surface of the drone bracket 11. A cross mounting groove 8 is opened at the center of the bottom surface of the battery box 1. A cross supporting frame 9 is bolted to the bottom surface of the cross mounting groove 8. An electronic gas fire extinguishing disk 10 is arranged between the inner bottom surface of the cross mounting groove 8 and the cross supporting frame 9. The surface of the cross supporting frame 9 is against the surface of the drone bracket 11.

[0030] Therefore, in this embodiment, the electronic gas fire extinguishing disk 10 and the drone bracket 11 can be separated by the cross supporting frame 9, and a part of the space can be reserved to prevent the drone bracket 11 from blocking the electronic gas fire extinguishing disk 10 and reducing the accuracy of temperature monitoring.

[0031] Furthermore, the inner bottom surface of the battery box 1 is provided with a plurality of battery compartments 2, and a battery main body 14 is provided inside the battery compartment 2. An arc flow channel 12 is opened on the side of the cross mounting groove 8. When the entire device is actually used, it is mainly used for surface clamping and installation of the drone bracket 11, and the drone is powered by external connection. The battery main body 14 generates heat during the power supply process, causing the temperature of the entire battery box 1 to rise. When the temperature rises to reach the temperature threshold set by the electronic gas fire extinguishing disk 10, the heptafluoropropane gas inside the electronic gas fire extinguishing disk 10 overflows, flows along the arc flow channel 12, and contacts the surface of the battery box 1 to cool the surface, thereby realizing intelligent temperature protection of the drone battery main body 14, preventing the battery from being damaged by overheating, and improving the safety of the entire device.

[0032] When the entire device is connected for power supply and use, a mainboard compartment 4 is provided on the top surface of the battery box 1, a control mainboard 5 is provided inside the mainboard compartment 4, a multi-channel line 6 is connected to the top surface of the control mainboard 5, and a multi-directional switch 7 is connected to the end of the multi-channel line 6. When the entire battery box 1 is actually used, the drone is mainly connected to the bottom surface of the external drone through the top of the multi-channel line 6 to power the drone. At the same time, the drone is connected to the surface of the drone bracket 11 through structures such as bolts and screw holes on the surface to connect the entire battery box 1 with the external drone and power it. The connection between the battery main body 14 inside each battery compartment 2 and the control mainboard 5 is controlled by the multi-directional switch 7, so as to realize the control of the power supply of each battery main body 14. A sealing cover 3 is provided at the corresponding position between the bottom surface of the battery box 1 and the battery compartment 2, and the sealing cover 3 is provided. One side edge of the cover 3 is hinged to the surface of the battery box 1, and the side surface of the sealing cover 3 away from the hinge is screwed to the surface of the battery box 1, and the bottom of the battery compartment 2 is sealed by the sealing cover 3. Opening the sealing cover 3 can realize the replacement and installation of the internal battery body 14, and it can be achieved that after the power supply of the battery body 14 inside a battery compartment 2 is completed, the multi-directional switch 7 is rotated counterclockwise or clockwise to the control switch of the next battery compartment 2 to power the next group of battery bodies 14, thereby realizing the guidance control of multiple battery bodies 14. Through this structure, the battery body 14 with insufficient power can be removed for replacement or charging, and the power supply of the entire drone is not affected during the disassembly process, so that the battery body 14 can be replaced and installed while the drone power supply is uninterrupted.

[0033] Furthermore, the arc-shaped flow channel 12 is evenly distributed in a linear array on the side of the cross mounting groove 8, the end of the arc-shaped flow channel 12 penetrates the bottom surface of the battery box 1, and the flow direction of the arc-shaped flow channel 12 is the longitudinal axis direction, ensuring that the arc-shaped flow channel 12 can be distributed along the inner wall of the cross mounting groove 8, so that the coverage area is larger during cooling, which is convenient for rapid cooling. The adjacent battery compartments 2 are of the same size, and the battery main body 14 is electrically connected to the control mainboard 5. A power display screen 13 is provided on the outer surface of the battery box 1 at a position corresponding to the battery compartment 2, and the power display screen 13 is electrically connected to the battery main body 14 through the control mainboard 5. The control motherboard 5 is connected to the battery body 14, and monitors the power according to the discharge current generated by the directional movement of electrons inside the battery body 14, and monitors the power percentage and the supported flight time through the power display screen 13, so as to facilitate real-time monitoring of the power of the battery body 14 and timely replacement when the power is insufficient. The bottom surface of the battery box 1 is evenly distributed with battery compartments 2, and the cross mounting groove 8 is located between adjacent battery compartments 2. The adjacent side connections on the outside of the battery box 1 are chamfered at 45 degrees, and the inner wall of the cross mounting groove 8 is gap-matched with the surface of the drone bracket 11. Specific embodiment 2:

[0035] The only difference between this embodiment and the first embodiment is that, in order to ensure the stability of the installation of the battery box 1 and the drone bracket 11, during the actual installation, screw holes can be provided on the outer surface of the battery box 1, and the edge of the battery compartment 2 adjacent to the battery box 1 can be positioned by bolts to prevent it from falling off.

[0036] When the battery box 1 is installed on the drone bracket 11, in addition to using its own structure for locking and positioning, additional bolts, screws and other structures can be added according to installation requirements for further fixing. Specific embodiment three:

[0038] The only difference between this embodiment and embodiment one or two is that, when actually in use, the electronic gas fire extinguishing disk 10 is provided with a temperature sensor and an MCU component on its surface, the temperature of the battery box 1 is sensed by the temperature sensor, and the temperature data is sent to the MCU, the gas release of the electronic gas fire extinguishing disk 10 is controlled by the MCU, and the temperature threshold of the temperature sensor is set by the MCU, thereby realizing the protection of the temperature of the battery box 1.

[0039] The principle of electronic gas fire extinguishing is based on Gaseous Fire Suppression (GFS) technology. By releasing active components in the electronic gas, such as fluoride ions and free radicals, the chemical environment of high-temperature areas is changed to achieve a cooling effect. Specific embodiment four:

[0041] The difference between this embodiment and any one of the first to third embodiments is that the drone bracket 11 and the battery box 1 need to be connected to an external drone when actually used, and used in conjunction with the drone. Figure 6 and Figure 7 As shown, during installation, the drone can be connected to the surface of the drone bracket 11 through a connecting rod arranged at the bottom. The specific connection method can adopt one or more of bolt connection, screw connection, mortise and tenon connection, or the bottom of the drone can be directly connected to the surface of the drone bracket 11 through bolts. In actual use, the surface of the drone bracket 11 is provided with corresponding grooves, screw grooves and other structures according to the drone connection method. While ensuring that the drone bracket 11 is connected to an external drone, the specific connection structure can be set in combination with the drone connection method in the prior art.

[0042] In summary, the present application 1 adopts a cross mounting groove 8 provided on the bottom surface of the battery box 1 to engage with the surface of the drone bracket 11, and uses the battery body 14 inside the multiple battery compartments 2 provided inside to power the drone connected externally, and uses the internal electronic gas fire extinguishing disk 10 to monitor the temperature. When the temperature of the battery body 14 is too high, the heptafluoropropane inside the electronic gas fire extinguishing disk 10 overflows and flows along the arc flow channel 12, and hits the surface of the battery box 1 to cool the surface, thereby realizing intelligent temperature protection of the drone battery body 14, preventing the battery temperature from being damaged by overheating, and improving the safety of the entire device;

[0043] At the same time, a cross mounting groove 8 is provided on the inner bottom surface of the battery box 1 to be snap-fitted with the surface of the drone bracket 11, and the battery body 14 inside the multiple battery compartments 2 arranged internally is used to power the externally connected drone, and the power supply is guided through the cooperation of the multi-directional switch 7 and the multi-channel line 6. An independent battery compartment 2 is provided to store the battery body 14, which is convenient for partial replacement of the battery body 14 without the need for overall disassembly and assembly, thereby facilitating the rapid installation of the battery box 1 and the drone body and the rapid replacement of the battery body 14.
