Embodiment 1

[0013] This embodiment provides a kind of unmanned aerial vehicle cabin door switch driven by double safety cutter, such as Figure 1 to Figure 3 As shown, it includes cutter body 1, locking hook 2, sheath 3, cutter 4 and ejector pin 5. One side of the cutter body is provided with two cavities for cutter installation, and the opposite side of the cutter body On the other side where the cutter is installed, there is a cutter body mounting seat. The cutter body mounting seat is composed of two ear seats arranged in parallel. The two cutter installation cavities are on the same level, and the two cavities are installed The cutter specifications and parameters are the same, the resistance of the cutter is 2-3.5Ω, the safety current is a DC current of 50mA for 1min without ignition, and the ignition current is 450-850mA; the locking hook is installed between the two ear sockets 10 through the shaft , the locking hook is located at the upper end of the rotating shaft and is provided...

Abstract

The invention discloses a cabin door switch of an unmanned aerial vehicle driven by double-insurance cutting machines. The cabin door switch comprises a cutting machine body, a locking hook, a jacket, cutting machines and a top latch, and is mainly applied to opening the cabin door of the unmanned aerial vehicle; by utilizing propulsive force of the cutting machine, the locking hook is pushed to be separated from a buckling ring of a cabin door cover; and by using the double cutting machine machines, the reliability of the cabin door switch is improved. The switch is small in size, is easy to control and is high in reliability.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle equipment, and relates to a hatch control switch, in particular to an unmanned aerial vehicle hatch switch driven by double safety cutters. Background technique [0002] During the flight of the UAV, the hatches are required to be tightly closed, but in some cases, the hatches are required to be opened in a controlled manner. For example, when the UAV is recovered, it is required to control the opening of the umbrella hatch. After the parachute drone opens the canopy in the air, the canopy flips backwards under the action of the airflow to throw out the guiding parachute. After the guiding parachute is taken out of the umbrella bag, the main parachute is opened, and the opened parachute carries the drone. Descend smoothly and land at a small speed. Parachute drones generally open the canopy in two ways: one is to open the canopy by controlling the electronically controlled lock of...
