[0003] During the charging and discharging processes of existing UAV batteries, a large amount of heat is generated. If the heat dissipation is poor, it will not only cause the battery temperature to rise, affecting the battery performance and service life, but may also pose a safety hazard. The heat dissipation area is small, and the battery is placed inside the UAV during use, which is not conducive to heat dissipation, resulting in a high local temperature and affecting the service life. Summary of the Utility Model

[0005] The utility model is realized as follows: An unmanned aerial vehicle with a battery heat dissipation function includes a body. An air inlet is opened at the front side of the bottom of the body, and an air outlet is opened at the rear side of the bottom of the body. A placement groove is opened inside the body between the air inlet and the air outlet. A first blocking door is rotatably arranged at the front side of the placement groove, and second blocking doors for blocking the first blocking door are rotatably arranged at both sides of the air inlet. Limiting blocks are arranged at the four corners inside the placement groove, and a battery is slidably arranged between the four limiting blocks. A positioning component for positioning the battery is arranged at the bottom of the placement groove, and an air flow channel for dissipating heat from the surface of the battery is formed between two adjacent limiting blocks.

Specific embodiments

[0018] In order to make the purpose, technical solutions and advantages of the present 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 the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a drone with a battery heat dissipation function, including a fuselage 1, an air inlet 2 is provided at the front side of the bottom of the fuselage 1, an air outlet 23 is provided at the rear side of the bottom of the fuselage 1, a placement groove 3 is provided inside the fuselage 1 and between the air inlet 2 and the air outlet 23, a first blocking door 18 is rotatably provided at the front side of the placement groove 3, and second blocking doors 19 for blocking the first blocking door 18 are rotatably provided at both sides of the air inlet 2. Limiting blocks 5 are provided at the four corners inside the placement groove 3, and a battery 4 is slidably provided between the four limiting blocks 5. A positioning component for positioning the battery 4 is provided at the bottom of the placement groove 3. An air flow channel 12 for dissipating heat from the surface of the battery 4 is formed between two adjacent limiting blocks 5. An air inlet hole 20 corresponding to the air flow channel 12 is provided at the front side of the first blocking door 18, and an air outlet hole 21 corresponding to the air flow channel 12 is provided at the rear side of the placement groove 3.

[0020] In this embodiment, the first blocking door 18 can use a clamping structure to fix the first blocking door 18 to ensure stability in the closed state.

[0021] The second blocking door 19 is in an open state under normal weather conditions. When it rains or in bad seasons, by closing the second blocking door 19, it is possible to prevent rainwater from entering the battery 4 and causing damage to the battery 4.

[0022] The first blocking door 18 and the second blocking door 19 can be controlled to open and close through a remote controller.

[0023] When the battery 4 ages and needs to be replaced, the battery 4 can be replaced by opening the first blocking door 18.

[0024] When the drone battery 4 starts to work, the heat generated will be dissipated through the surface of the battery 4. External cold air enters the air inlet 2, then enters the air flow channel 12 through the air inlet hole 20 at the front side of the first blocking door 18. The cold air flows in the air flow channel 12, contacts the surface of the battery 4 and absorbs heat, and then becomes hot air. The hot air flows to the air outlet hole 21 at the rear side of the placement groove 3 and then is discharged outside the fuselage 1 through the air outlet 23. In this way, a continuous air convection is formed, effectively reducing the surface temperature of the battery 4 and improving the overall safety and reliability of the drone.

[0025] Furthermore, a power input module 13 is provided at the rear side of the battery 4, a power connection module 14 adapted to the power input module 13 is provided at the rear side of the placement groove 3. A convex strip 17 is provided at the rear side of the battery 4 and on one side of the power input module 13. A rubber sleeve 15 is sleeved on the surface of the power connection module 14, and a plurality of second grooves 16 adapted to the convex strip 17 are provided on the surface of the rubber sleeve 15.

[0026] In this embodiment, the rubber sleeve 15 not only provides good insulation performance but also reduces the vibration and impact of the battery 4 during flight.

[0027] By docking the convex strip 17 with the second groove 16, the stability and accuracy of the electrical connection between the battery 4 and the airframe 1 are ensured.

[0028] Furthermore, a positioning block 6 is fixedly connected to the bottom of the battery 4. A first groove 7 is formed inside the positioning block 6. The positioning assembly includes a positioning groove 22 provided at the bottom of the placement groove 3. A fixing block 8 that can be inserted into the first groove 7 is movably provided in the positioning groove 22. A telescopic spring 10 is provided between the bottom end of the fixing block 8 and the positioning groove 22. A movable rod 9 is fixedly connected to the top of the fixing block 8. A handle 11 is rotatably provided at the bottom of the movable rod 9.

[0029] In this embodiment, when the battery 4 needs to be positioned, first rotate the handle 11 to drive the movable rod 9 to descend, thereby driving the fixing block 8 to descend, so that the fixing block 8 is in the positioning groove 22 and does not interfere with the insertion of the battery 4 into the placement groove 3. Then insert the battery 4 into the placement groove 3. After the power input module 13 is docked with the power connection module 14, rotate the handle 11 to drive the movable rod 9 to ascend, thereby driving the fixing block 8 to ascend, so that the fixing block 8 is inserted into the first groove 7, and positioning can be carried out.

[0030] When the battery 4 needs to be removed, rotate the handle 11 to drive the movable rod 9 to descend, thereby driving the fixing block 8 to descend, so that the fixing block 8 is disengaged from the first groove 7 and the fixing block 8 is in the positioning groove 22, and the battery 4 can be taken out.

[0031] The working principle and usage process of the present utility model: After the present utility model is installed, when the drone battery 4 starts to work, the heat generated will be dissipated through the surface of the battery 4. External cold air enters the air inlet 2 and then enters the air flow channel 12 through the air inlet holes 20 on the front side of the first sealing door 18. The cold air flows in the air flow channel 12, contacts the surface of the battery 4 and absorbs heat, and then becomes hot air. The hot air flows to the air outlet holes 21 at the rear side of the placement groove 3 and then is discharged outside the airframe 1 through the air outlet 23. In this way, a continuous air convection is formed by repeating the cycle.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
