Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment:

a high-strength bottom protection plate of an unmanned aerial vehicle comprises an unmanned aerial vehicle main body 1 and supports 2, wherein four groups of supports 2 are arranged at the bottom end of the unmanned aerial vehicle main body 1 at equal intervals, sliding grooves 3 are formed in the four groups of supports 2, first springs 4 are sleeved in the four groups of sliding grooves 3, a protection plate 5 is arranged at the lower part of the unmanned aerial vehicle main body 1, movable grooves 6 are formed in four corners of the protection plate 5, limit blocks 7 are welded in the four groups of movable grooves 6, the limit blocks 7 are sleeved in the sliding grooves 3, when the unmanned aerial vehicle is used, the sliding grooves 3 can be matched with the limit blocks 7 when the protection plate 5 slides along the supports 2 through the design, so that the protection plate 5 is more stable when sliding along the supports 2, the stability of the device when sliding is improved, the four groups of movable grooves 6 are respectively sleeved outside the four groups of supports 2, the bottom ends of the four groups of supports 2 are all in threaded connection with, and the diameter of the limit bolt 8 is larger than that of the movable groove 6, and through the design, the limit bolt 8 can limit the movable groove 6, so that the guard plate 5 can only move in the range limited by the limit bolt 8, and the normal use of the device is ensured.

The middle part of the protection plate 5 is provided with a waterproof device, the waterproof device comprises a limiting groove 9, a limiting ring 10, a protective cover 11, a second spring 12, a touch switch 13 and an LED lamp tube 14, the central position of the protection plate 5 is provided with the limiting groove 9, the bottom end of the limiting groove 9 is welded with the limiting ring 10 in a thermoplastic mode, the protective cover 11 is sleeved inside the limiting ring 10, the two sides of the bottom end of the protective cover 11 are provided with transverse extending parts, the length of the protective cover 11 is equal to the distance between the protection plate 5 and the bottom end of the unmanned aerial vehicle main body 1, through the design, when the protective cover 11 receives buoyancy of water and thrust of the ground, the protective cover 11 can play a protective role on a camera at the bottom of the unmanned aerial vehicle main body 1, so that the normal use of the device is ensured, the protective cover 11 is elastically connected with the bottom end of the limiting ring 10 through the second spring 12, the LED lamp tube 14 is glued to the, touch switch 13's input passes through the wire and is connected with 1 internal power supply electricity of unmanned aerial vehicle main part, there is touch switch 13 bottom left side of unmanned aerial vehicle main part 1 through the screw fixation, touch switch 13's vertical horizontal position and the vertical horizontal position of the left side wall of protection casing 11 are in same vertical line, through this design, when protection casing 11 moves upwards along spacing groove 9 and spacing ring 10, protection casing 11's top can contact each other with touch switch 13, thereby make protection casing 11 play the camera and play the switch-on circuit and make LED fluorescent tube 14 luminous when waterproof effect, so that the user seeks.

The working principle is as follows: when there is more debris in the place that unmanned aerial vehicle main part 1 descends, backplate 5 receives the promotion of debris and receives ascending effort, backplate 5 atress is along support 2 rebound, stopper 7 is along spout 3 up-sliding under the drive of backplate 5, first spring 4 contracts under stopper 7 and spout 3 combined action and holds the power, when the bottom of support 2 and ground contact, backplate 5 reachs the biggest rise height, when picking up unmanned aerial vehicle main part 1 again, first spring 4 resumes to initial form, backplate 5 removes to initial position department along spout 3 through stopper 7 under the effect of the elastic force of first spring 4.

When unmanned aerial vehicle main part 1 met the condition that ground has ponding at the descending in-process simultaneously, the bottom and the surface of water of protection casing 11 contacted each other, and protection casing 11 moves upwards along spacing groove 9 and spacing ring 10 under the effect of the buoyancy of the promotion on ground and the surface of water, when the top of protection casing 11 with touch switch 13 contacted each other, the power supply of 1 internal power source of unmanned aerial vehicle main part to LED fluorescent tube 14, LED fluorescent tube 14 is luminous.
