Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle cooling, in particular to a device for cooling an unmanned aerial vehicle using airflow. Background Art

[0002] With the advancement of technology, drones can be seen frequently in our daily life. A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an onboard computer. It usually consists of a flight control system and an autonomous navigation system, and can perform flight missions through remote control or preset navigation plans.

[0003] During the flight of the drone, the battery is needed to provide it with energy. However, the battery is prone to heat up when used for a long time or in a high temperature environment. Once overheated, the drone is likely to lose control or even be damaged. Therefore, it is necessary to dissipate heat. When the existing drone cools the battery through airflow, the cooling range is small and the cooling effect needs to be improved. Therefore, a device for cooling the drone using airflow is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that when the existing drone cools the battery through airflow, the cooling range is small and the cooling effect needs to be improved, and proposes a device for cooling the drone using airflow.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for cooling a drone using airflow, comprising a drone body, a bottom shell installed at the bottom of the drone body, a partition plate arranged between the bottom shell and the bottom of the drone body, a battery compartment for placing batteries arranged in the drone body, a heat dissipation hole arranged on the surface of the partition plate, at least one horizontal groove and an inclined ventilation groove arranged on both sides of the drone body, the ventilation groove is connected to the horizontal groove and to the partition plate, a second air outlet hole connected to the horizontal groove is arranged at one end of the drone body, and a first air outlet hole for air outlet is arranged at one end of the bottom shell close to the second air outlet hole;

[0007] An air inlet is provided at the bottom of the bottom shell, and an air inlet mechanism is arranged in the air inlet. The air inlet mechanism is arranged at the bottom of the bottom shell for air intake.

[0008] As a further solution of the utility model, the air intake mechanism includes a mounting shaft, which is fixedly connected to the bottom of the bottom shell. The mounting shaft is circularly connected to a closing plate used in conjunction with the air inlet. Torsion springs are fixedly connected between both sides of the closing plate and the mounting shaft. A limit plate for limiting the angle of the closing plate is fixedly connected to the side of the closing plate close to the mounting shaft. A second air guide plate inclined downward is provided on the side of the closing plate away from the mounting shaft, and a gap is provided between the second air guide plate and the bottom of the bottom shell.

[0009] As a further solution of the utility model, the inner walls on both sides of the bottom shell are fixedly connected with guide rails, a filter screen is slidably connected between the two guide rails, and the bottom of the filter screen is in contact with the surface of the closing plate.

[0010] As a further solution of the utility model, a baffle used in conjunction with the filter screen is fixedly connected to the bottom of the partition, and the baffle is located on one side of the filter screen and is in contact with the filter screen.

[0011] As a further solution of the utility model, a plurality of first protective columns are fixedly connected in the first air outlet.

[0012] As a further solution of the utility model, a second protective column is fixedly connected to each of the second air outlets.

[0013] As a further solution of the utility model, the bottom of each of the ventilation slots is fixedly connected with a first air guide plate which is arranged obliquely.

[0014] In the present application, when the drone body is flying, when the airflow passes through the second air guide plate, the wind force is used to blow the second air guide plate, thereby causing the closing plate to rotate downward, and then natural air is guided into the bottom shell through the closing plate, and then part of the air is discharged through the first air outlet, thereby carrying the heat from the bottom of the battery. At the same time, part of the air enters the ventilation groove under the guidance of the first air guide plate, and then is discharged through the second air outlet after passing through the horizontal groove, thereby taking away the heat from the side of the battery, and the heat dissipation effect is better. When the closing plate rotates downward, the filter moves downward under the action of its own weight, and then filters the air to prevent flying insects or other foreign objects from entering the bottom shell. When not in use, the closing plate is reset under the action of the torsion spring, which is convenient for product storage and prevents the closing plate from breaking.

[0015] Beneficial effects:

[0016] In the utility model, the device for cooling the drone by airflow is provided by providing ventilation slots and transverse slots on the inner wall of the drone body. The ventilation slots and transverse slots are used in combination to allow air to pass through the sides of the battery, thereby improving the heat dissipation effect on the battery.

[0017] In the utility model, the drone uses an airflow cooling device, and the closing plate can be rotated through the setting, so that when the product is not in use, the closing plate can be reset under the action of the torsion spring, which is convenient for product storage and avoids the closing plate from breaking;

[0018] In the utility model, ventilation grooves and transverse grooves are arranged on the inner side wall of the drone body. The ventilation grooves and the transverse grooves are used in combination to allow air to pass through the sides of the battery, thereby improving the heat dissipation effect on the battery. At the same time, when the product is not in use, the closing plate can be reset under the action of the torsion spring, which is convenient for product storage and avoids the closing plate from breaking.
