[0024] As a technical optimization solution of the present invention, by providing a baffle 7, the card board 4 can be shielded and protected to avoid the card board 4 being accidentally touched, thereby improving the working stability of the card board 4.

[0025] refer to Figure 2 A rubber pad 8 is fixedly connected to the surface of the return-shaped limit frame 2, and the top of the rubber pad 8 is fixedly connected to the surface of the drone body 1.

[0026] As a technical optimization solution of the utility model, by providing a rubber pad 8, the stability between the U-shaped transparent protective plate 3 and the drone body 1 can be filled, thereby preventing the U-shaped transparent protective plate 3 from loosening during use.

[0027] refer to Figure 2 The front and rear sides of the inner wall of the U-shaped transparent protective plate 3 are both provided with trapezoidal grooves 9, and a trapezoidal block 10 is arranged inside the trapezoidal groove 9, and the surface of the trapezoidal block 10 is fixedly connected to the surface of the return-shaped limit frame 2.

[0028] As a technical optimization solution of the utility model, by providing the trapezoidal groove 9 and the trapezoidal block 10, the U-shaped transparent protective plate 3 can be limited to avoid shaking of the U-shaped transparent protective plate 3 during use.

[0029] refer to Figure 3A transparent plate 11 is fixedly connected to the front and rear sides of the inner cavity of the U-shaped transparent protective plate 3 , and the height of the transparent plate 11 is less than the height of the U-shaped transparent protective plate 3 .

[0030] As a technical optimization solution of the present invention, by providing a transparent plate 11, the front and rear sides of the lens of the drone body 1 can be protected to avoid damage to the lens of the drone body 1.

[0033] The working principle and use process of the utility model are as follows: when the drone body 1 lands, it drives the U-shaped transparent protective plate 3 and the transparent plate 11 to move downward. When the drone body 1 touches the ground, the U-shaped transparent protective plate 3 blocks the protrusions on the ground and contacts the bottom of the drone body 1. The transparent plate 11 blocks and protects the front and rear sides of the bottom of the drone body 1. When the U-shaped transparent protective plate 3 needs to be removed, the top of the card plate 4 is pushed to rotate toward the side close to the shrapnel 5. The shrapnel 5 is compressed by the card plate 4, and the bottom of the card plate 4 is separated from the card block 6. At this time, the U-shaped transparent protective plate 3 loses its fixation and moves downward. The U-shaped transparent protective plate 3 drives the trapezoidal groove 9 to separate from the trapezoidal block 10. At this time, the U-shaped transparent protective plate 3 is disassembled. When the U-shaped transparent protective plate 3 needs to be used, the above-mentioned disassembly steps can be reversed to complete the installation, thereby having the effect of bottom anti-collision.

[0034] To sum up: the bottom anti-collision device for the drone has the advantage of bottom anti-collision through the coordinated use of the drone body 1, the return limit frame 2, the U-shaped transparent protective plate 3, the card plate 4, the shrapnel 5 and the card block 6, and solves the problem that the traditional drone lacks a bottom anti-collision structure. When the drone lands on the ground, when there are protrusions on the ground, the protrusions will hit the bottom of the drone, which can easily reduce the safety of the drone.
