Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation for unmanned aerial vehicles, in particular to a battery heat dissipation structure for surveying and mapping unmanned aerial vehicles. Background Art

[0002] Drone mapping is a technology that uses drones and high-precision measurement equipment such as lidar to collect and map geographic data. Through the lidar, camera, GPS, inertial navigation system and other devices carried by the drone, spatial information such as the ground, buildings, and terrain can be quickly and efficiently acquired, and accurate three-dimensional models and maps can be generated. The power supply of the drone comes from the built-in battery, and the drone battery is usually fixed inside the drone through a battery box to maintain the normal power supply of the drone. The heat generated during the battery operation needs to be discharged, thereby reducing the heat loss generated by the battery and extending the battery life.

[0003] Currently, when the battery temperature is too high, the method used is to let it stand for a period of time for natural cooling, but natural cooling takes a lot of time and cannot supply power, thus affecting the operation of the drone equipment. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a battery heat dissipation structure for a surveying and mapping UAV, which is characterized by comprising a battery box, a box cover, a suction fan, an exhaust fan, a grille plate, and a limit spring. A connection box cover is arranged on one side of the upper end of the battery box, and a mounting groove is arranged on the bottom of the battery box, wherein a suction fan is installed in one of the mounting grooves, and an exhaust fan is installed in the other mounting groove. Grooves are arranged on the longer side walls on both sides of the battery box, and the grille plate is connected at the notch of the groove of the battery box. A limit spring is fixedly connected to the shorter side wall on one side of the battery box.

[0005] A plurality of ventilation channels are arranged on the bottom of the groove on the battery box, and the other end port of the ventilation channel is located at the notch of the installation groove of the battery box.

[0006] T-shaped blocks are provided on the outer walls of the longer side panels on both sides of the battery box.

[0007] The battery box is slidably connected in a T-shaped slot arranged on the drone body through a T-shaped block.

[0008] Furthermore, a ventilation hole is provided on the bottom of the battery installation slot provided on the drone body.

[0009] Furthermore, the battery is fixed in the battery box via a limit spring.

[0010] Furthermore, the battery box is provided with a snap-on connection component with the drone body, which is limited and fixed after installation.

[0011] Beneficial effects of the utility model:

[0012] The utility model installs a suction fan and an exhaust fan on the bottom surface of the battery box where the motor is installed, so as to enhance the air circulation in the battery box to process the heat generated during battery operation and effectively dissipate heat. In addition, grid plates are installed at the grooves and notches arranged on the side walls on both sides of the battery box. The grid plates and the bottom of the grooves arranged on the battery box form a chamber. The gas entering the battery box enters the chamber through the ventilation duct, takes away the heat in the chamber, and improves the heat dissipation efficiency of the battery.
