Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles with a heat dissipation structure, in particular to a unmanned aerial vehicle with a heat dissipation structure. Background Art

[0002] 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. If a drone is left stationary for a long time while flying or in a standby state, the temperature of the fuselage may continue to rise. Long-term high temperature will affect the service life of the drone, so the drone needs to be equipped with a heat dissipation component;

[0003] For example, a drone with a heat dissipation structure disclosed in the utility model with authorization announcement number CN216626444U includes: a control box, the bottom end of the control box is detachably connected to a base plate, one side of the bottom end of the base plate is connected to a motor by bolts, the output end of the motor is fixedly connected to a No. 1 fan blade, a No. 2 fan blade is installed on the bottom end of the base plate and on the side away from the No. 1 fan blade, a transmission mechanism is arranged between the No. 1 fan blade and the No. 2 fan blade, the central axis of the No. 2 fan blade is rotatably connected to the bottom end of the base plate through the transmission mechanism, and a temperature sensor is fixedly installed in the middle of the upper end of the base plate. The utility model has the following advantages: by arranging the No. 1 fan blade, the No. 2 fan blade, the transmission mechanism and the temperature sensor, the temperature sensor can detect the temperature inside the control box. Temperature. When the temperature of the control box is at normal level, the No. 1 fan blade rotates for normal heat dissipation. When the temperature is too high, the temperature sensor transmits a signal to the electric telescopic rod of the transmission mechanism, so that the transmission mechanism drives the No. 1 and No. 2 fan blades to rotate at the same time to increase the air volume. A motor is connected to one side of the bottom end of the bottom plate of the device by bolts, and the output end of the motor is fixedly connected to the No. 1 fan blade. The No. 2 fan blade is installed on the bottom end of the bottom plate and on the side away from the No. 1 fan blade. The direction of the blade for heat dissipation is downward and lower than the control box. When the drone lands, the lower end of the blade will touch the ground, making it inconvenient for the drone to land. In addition, a through hole is opened on the bottom plate of the device, and dust will enter the control box when air circulates, making subsequent cleaning inconvenient. Utility Model Content

[0018] 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, 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.

[0019] Example

[0020] Please refer to Figure 1 - Figure 4 As shown, the utility model provides a drone with a heat dissipation structure, including a lower protective shell 1 and an upper protective shell 2. Connecting solenoids 4 are formed at diagonal positions inside the shells of the lower protective shell 1 and the upper protective shell 2. A connecting screw 3 passing through the connecting solenoid 4 is passed through the upper protective shell 2. The upper end of the connecting screw 3 is not provided with a thread. The connecting screw 3 is screwed with the connecting solenoid 4 located in the lower protective shell 1 below. A connecting plate 5 is formed at a diagonal position outside the upper protective shell 2. A power motor 7 is installed at the end of the connecting plate 5. A power blade 6 is fixedly installed on the output shaft of the power motor 7. A card slot 15 is opened on the upper end surface of the lower protective shell 1. A convex plate 16 is formed on the lower end surface of the upper protective shell 2. The convex plate 16 can be inserted into the card slot 15, so that the connection between the upper protective shell 2 and the lower protective shell 1 is more stable.

[0021] When connecting the upper protective shell 2 and the lower protective shell 1, insert the convex plate 16 on the lower end surface of the upper protective shell 2 into the slot 15 on the upper end surface of the lower protective shell 1, and then screw the connecting screw 3 to screw it with the connecting screw 4 inside the lower protective shell 1 to connect the upper protective shell 2 and the lower protective shell 1;

[0022] like Figure 1 - Figure 4 As shown, the front and rear side walls of the lower protective shell 1 are both provided with mounting grooves 8, a filter frame 9 is fixed to the outside of the mounting groove 8 by mounting screws 10, a filter screen 11 is laid on the filter frame 9, mounting frames 12 are formed on the front and rear inner walls of the lower protective shell 1, and left-right symmetrical cooling fans 13 are arranged on the mounting frames 12, and a supporting frame 14 is arranged on the lower surface of the lower protective shell 1. After installation, the two sets of cooling fans 13 have the same blowing direction, which is convenient for accelerating heat dissipation;

[0023] When heat dissipation is required, the cooling fans 13 are controlled by the remote control to operate. One group of cooling fans 13 introduces outside air, and the other group of cooling fans 13 draws out the internal air, so as to speed up the air circulation and replacement. After the air is filtered by the filter screen 11 on the filter frame 9, dust and debris are intercepted, and the amount of dust entering the lower protective shell 1 is reduced. When disassembling and cleaning, the filter screen 11 is disassembled and cleaned, and it is determined whether the interior needs to be cleaned according to the actual situation;

[0024] Specific working principle:

[0025] Before using the device, insert the convex plate 16 on the lower end face of the upper protective shell 2 into the groove 15 on the upper end face of the lower protective shell 1, then screw the connecting screw 3 to screw it with the connecting screw 4 inside the lower protective shell 1, connect the upper protective shell 2 and the lower protective shell 1, control the power motor 7 through the remote control to drive the power blades 6 to rotate, complete the take-off, and control the cooling fan 13 to run through the remote control. One group of cooling fans 13 introduces outside air, and the other group of cooling fans 13 draws out internal air to speed up air circulation and replacement. After the air is filtered by the filter 11 on the filter frame 9, dust and debris are trapped.
