[0034] As Figure 1 and Figure 2 shown, the parachute installation mechanism provided by the embodiment of the present utility model includes: a hoop belt 100, a first buckle member 200, and a second buckle member 300 connected to the parachute assembly 400; the hoop belt 100 is used to tighten the fuselage 500 of the unmanned aerial vehicle, and the first buckle member 200 is connected to the hoop belt 100; the second buckle member 300 is adapted to and detachably connected to the first buckle member 200.

[0035] In an alternative embodiment, the hoop belt 100 can be configured with a shrinking elastic force to tighten the fuselage 500 of the unmanned aerial vehicle. In this embodiment, to improve the stability of the parachute installation mechanism, the hoop belt 100 adopts a rigid structure and is tightened by a buckle 120, thereby tightening the fuselage 500 of the unmanned aerial vehicle. The second buckle member 300 is adapted to and detachably connected to the first buckle member 200. The disassembly and replacement of the parachute assembly 400 can be achieved by disassembling the second buckle member 300 and the first buckle member 200, and the operation is more convenient.

[0036] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in the embodiment of the present utility model, the first buckle member 200 is provided with a chute 201, and the second buckle member 300 includes a slider 301 adapted to the chute 201. During assembly, the slider 301 is slidably engaged with the chute 201, so that the first buckle member 200 and the second buckle member 300 can be cooperatively connected.

[0037] In addition, the top of the chute 201 is open and the bottom is closed. The slider 301 is slidably engaged with the chute 201 from top to bottom, and the closed structure at the bottom of the chute 201 bears the slider 301, so as to ensure that the second buckle member 300 is assembled in place relative to the first buckle member 200 and the position is relatively stable.

[0038] As Figure 3 and Figure 5 shown, the first buckle member 200 further includes an elastic plunger 202, and the extending direction of the elastic plunger 202 is perpendicular to the extending direction of the chute 201; the second buckle member 300 or the parachute assembly 400 is provided with a positioning hole 401 adapted to the elastic plunger 202; in the state where the first buckle member 200 is connected to the second buckle member 300, the elastic plunger 202 is engaged with the positioning hole 401, thereby improving the accuracy of alignment between the first buckle member 200 and the second buckle member 300, and the elastic force of the elastic plunger 202 relieves the problem of relative looseness and tremor between the first buckle member 200 and the second buckle member 300.

[0039] In addition, the elastic plunger 202 has a spherical head adapted to the positioning hole 401. When disassembling, the spherical head can be slid out of the positioning hole 401 under the action of an external force, so as to ensure that the first buckle member 200 and the second buckle member 300 can be smoothly disassembled.

[0040] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, the strap 100 includes: a belt body 110 and a buckle 120 connecting the belt body 110; in the state where the buckle 120 is locked, the buckle 120 pulls the belt body 110, so that the belt body 110 contracts and tightens the fuselage 500 of the drone.

[0041] In an alternative embodiment, the buckle 120 can be a snap device or a threaded fastener for tightening the belt body 110, so that the belt body 110 contracts and tightens the fuselage 500 of the drone.

[0042] In this embodiment, anti-slip bumps 101 are provided on the inner side of the belt body 110. By contacting the fuselage 500 of the drone through a plurality of spaced anti-slip bumps 101, the friction force is increased to prevent the belt body 110 from sliding relative to the fuselage 500 of the drone.

[0043] In this embodiment, the belt body 110 encloses to form a tightening area and has a first movable end 111 and a second movable end 112; the buckle 120 includes a hook portion 121 connected to the first movable end 111 and a fastening portion 122 connected to the second movable end 112, and the fastening portion 122 is adapted to the hook portion 121.

[0044] Further, the fastening portion 122 includes: a lock sleeve 1221 and a dial 1222; the dial 1222 is hinged to the belt body 110 around a first rotating shaft 1223, the lock sleeve 1221 is hinged to the dial 1222 around a second rotating shaft 1224, and the first rotating shaft 1223 and the second rotating shaft 1224 are parallel and spaced apart; in the locked state of the buckle 120, the lock sleeve 1221 is hooked on the hook portion 121, the acting force of the belt body 110 makes the dial 1222 tend to fit the belt body 110, and makes the first rotating shaft 1223 located between the hook portion 121 and the second rotating shaft 1224. In the locked state, the dial 1222 pulls the lock sleeve 1221 through the second rotating shaft 1224, the lock sleeve 1221 hooks the hook portion 121, and then can pull the first movable end 111 and the second movable end 112 closer, and the tightening area formed by the belt body 110 is tightened, so as to tighten the fuselage 500 of the drone.

[0045] The drone provided by the embodiment of the present invention is equipped with the parachute installation mechanism described in the above embodiment, and the drone has the technical effects of the above parachute installation mechanism, which will not be elaborated here.

[0046] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
