[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Referring to Figures 1-5 , an embodiment provided by the present utility model: a stable mechanism for UAV mapping, including a body 1. Fixed plates 2 are integrally provided at four ends of the body 1. Propellers 3 are provided at one ends of the four fixed plates 2. Support rods 4 are installed at the four corners of the bottom end of the body 1. The bottom ends of two support rods 4 on the same side are provided with a bottom plate 6. A pair of mounting plates 7 are installed at the bottom ends of the two bottom plates 6. A plurality of steel wire ropes 11 are provided in the middle of the two pairs of mounting plates 7. Support plate members 10 are installed at the bottommost parts of the two pairs of mounting plates 7. By installing a pair of mounting plates 7 at the bottom ends of the two bottom plates 6 and arranging a plurality of steel wire ropes 11 in the middle of the two pairs of mounting plates 7, when the UAV lands on the ground, the support plate member 10 at the bottom of the mounting plate 7 contacts the ground first. The contact stress between the two causes the plurality of annular steel wire ropes 11 to be compressed for buffering, avoiding the situation that the contact stress between the support plate member 10 and the ground is too large and causing the body 1 to tip over. This not only improves the stable structure of the body 1 but also enhances the safety performance of the UAV.

[0029] A first motor 13 is provided in the middle of the interior of the body 1. A fixed frame 14 is provided at the output end of the first motor 13. A camera 16 is rotatably provided in the middle of the fixed frame 14. A second motor 15 is provided inside one end of the fixed frame 14. The output end of the second motor 15 is connected to the camera 16. By designing the first motor 13, it is convenient to control the rotation of the fixed frame 14. By designing the second motor 15, it is convenient to control the rotation of the camera 16, greatly improving the monitoring range of the camera 16. A pair of fixing bolts 5 are provided at the connection between the four support rods 4 and the body 1. Arranging a pair of fixing bolts 5 at the connection between the four support rods 4 and the body 1 facilitates the replacement of the support rods 4 in the later stage. At both ends of the connection between the two pairs of mounting plates 7 and the bottom plate 6 and the support plate member 10, connection bolts 8 are installed. Threaded sleeves of connection nuts 9 are provided at one ends of the eight connection bolts 8. By using the cooperation between the connection bolts 8 and the connection nuts 9, the entire buffering structure of the steel wire rope 11 is installed between the bottom plate 6 and the support plate member 10, facilitating the replacement of the damaged buffering structure and the support plate member 10 in the later stage and reducing the maintenance cost of the UAV. Half holes 12 are opened on both sides of the bottom ends of the two support plate members 10. By opening half holes 12 on both sides of the bottom ends of the two support plate members 10, it is avoided that the connection bolts 8 protrude and affect the flatness of the support plate member 10.

[0030] Working principle: A pair of mounting plates 7 are installed at the bottom ends of two base plates 6, and a plurality of wire ropes 11 are arranged in the middle of these two pairs of mounting plates 7. When the drone lands on the ground, the support plate members 10 at the bottom of the mounting plates 7 first come into contact with the ground, and the contact stress between the two causes the plurality of annular wire ropes 11 to be compressed for buffering, avoiding the situation that the contact stress between the support plate members 10 and the ground is too large, which may cause the body 1 to roll over. This not only improves the stable structure of the body 1 but also enhances the safety performance of the drone. The buffer structure of the entire wire rope 11 is installed between the base plate 6 and the support plate members 10 through the combined use of connecting bolts 8 and connecting nuts 9, which facilitates the replacement of the damaged buffer structure and support plate members 10 in the later stage and reduces the maintenance cost of the drone.
