Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle protection, in particular to a propeller protection frame for an unmanned aerial vehicle. Background Art

[0002] The function and use of drones is aerial photography. Both photographers and filmmakers cannot do without the support of drones. Drones can also be used in agriculture. Farmers can use drones to spray pesticides on a large scale.

[0003] Some existing drones do not have their propellers protected. When the operator controls the drone to fly at low altitude in a place with trees, the operator may cause the drone's propeller to hit some branches or flying birds if he is not careful. In order to fly, the propeller of the drone often rotates at a faster speed. The high-speed rotating propeller is easily damaged when it hits these things, thus causing a crash. For this reason, we provide a drone propeller protection framework to solve the above problems. Utility Model Content

[0014] III) Beneficial effects

[0015] Compared with the prior art, the UAV propeller protection frame has the following beneficial effects:

[0016] The utility model cooperates with the top cover and the limiting mechanism and other components. First, the top cover can protect the propeller. After the top cover is placed inside the protective frame, the propeller will be protected inside the protective frame, so that other objects cannot easily touch the propeller, thereby preventing the propeller from being damaged. The limiting mechanism can limit the position of the plug-in block. After the top cover is inserted into the protective frame, the plug-in block can be inserted into the top cover to fix the position of the top cover. Then the limiting mechanism fixes the position of the plug-in block to prevent the plug-in block from detaching from the top cover, thereby preventing the top cover from falling from the protective frame. It is very convenient and solves the problem that the propeller is easily touched by other objects.

[0017] The utility model cooperates between the insert block and the limit shell, so that when the top cover is put into the protective frame, the top cover will move with the limit block, so that the limit block is inserted into the protective frame first, so as to prevent one side of the top cover from tilting up during the take-off of the drone. The limit shell can limit the position of the insert block, so that the top cover cannot move directly upward, so as to prevent the insert block from being unable to limit the position of the top cover, which is very easy to use.

[0027] The outer surface of the top cover 5 is fixedly connected to the limit block 7, and the upper surface of the top cover 5 is slidably connected to the insert block 8. The top cover 5 will fix the position of the limit block 7, and will move with the limit block 7 when the top cover 5 moves. The position of the top cover 5 is limited by inserting the insert block 8 into the interior of the top cover 5.

[0028] The outer surface of the plug block 8 is fixedly connected with a spring 9, and the outer surface of the plug block 8 is slidably connected with a limit shell 10. A limit mechanism 11 is arranged above the fuselage body 1. The spring 9 can push the plug block 8 to move after being compressed, and the limit shell 10 can limit the direction in which the plug block 8 can move, thereby avoiding deviation in the moving position of the plug block 8.

[0029] The limiting mechanism 11 includes a slider 1101, the outer surface of the slider 1101 is slidably connected to the inside of the plug block 8, the outer surface of the slider 1101 is slidably connected to a support block 1102, the upper surface of the support block 1102 is fixedly connected to the bottom surface of the limiting shell 10, and the position of the plug block 8 is limited by inserting the slider 1101 into the inside of the plug block 8, so that the plug block 8 cannot move, and the support block 1102 can control the position to which the slider 1101 can move, thereby avoiding deviation in the moving position of the slider 1101.

[0030] The outer surface of the support block 1102 contacts the outer surface of the protective frame 3, and the bottom surface of the support block 1102 is fixedly connected to the upper surface of the fuselage body 1. The support block 1102 can prevent the protective frame 3 from vibrating, and the position of the support block 1102 is fixed by the fuselage body 1.

[0031] The support block 1102 is internally slidably connected to a slide bar 1103, the upper surface of the slide bar 1103 is fixedly connected to the bottom surface of the slider 1101, and the support block 1102 can control the direction of movement of the slide bar 1103 to avoid deviation in the position of the slide bar 1103, and will move with the slide bar 1103 when the slider 1101 moves.

[0032] A spring 2 1104 is fixedly connected inside the support block 1102. One end of the spring 2 1104 away from the support block 1102 is fixedly connected to the bottom surface of the slider 1101. The spring 2 1104 is sleeved on the outer surface of the slide bar 1103. The support block 1102 will fix the position of the spring 2 1104, and when the spring 2 1104 is compressed, it can push the slider 1101 to move.

[0035] The upper surface of the insert block 8 is fixedly connected with a resistance-increasing block 12, and a support foot 13 is installed under the fuselage body 1. The resistance-increasing block 12 allows the user to move the insert block 8 more easily, and the support foot 13 can make it easier for the fuselage body 1 to land.

[0036] Working principle: When using the device, you first need to screw the protective frame 3 onto the support rod 2, then install the propeller on the fuselage body 1, and put the top cover 5 onto the protective frame 3. At this time, you need to insert the limit block 7 into the protective frame 3 first, and then put the top cover 5 flat. The spring 1 9 will push the plug block 8 into the top cover 5, so that the top cover 5 cannot move. After the plug block 8 is inserted into the appropriate position inside the top cover 5, the spring 2 1104 will push the support block 1102 into the plug block 8, thereby completely fixing the position of the plug block 8, so that the propeller will be protected in the protective frame 3 and the top cover 5.
