[0020] The following is combined with Figure 1-4 The utility model is further described with reference to the accompanying drawings and implementation methods.
[0021] A shock-absorbing landing gear for a surveying and mapping UAV for surveying and mapping geographic information includes a base 7, the upper side of which is fixedly connected to symmetrical fixing blocks 9, the upper sides of which are respectively hinged to the two ends of a connecting block 10, the connecting block 10 being triangular in shape, and the two fixing blocks 9 being arranged along the same straight line;
[0022] The two sides of the upper end of the connecting block 10 are respectively hinged to one end of the connecting rod 1 2, and the two sides of the middle part of the connecting block 10 are respectively hinged to one end of the connecting rod 2 11. The connecting rod 1 2 and the connecting rod 2 11 are arranged in parallel. The other ends of the two connecting rods 1 2 are respectively hinged to the two sides of the upper end of the support block 17, and the two sides of the lower end of the support block 17 are respectively hinged to the other ends of the two connecting rods 2 11. The upper sides of the two connecting rods 1 2 are fixedly connected to the drone platform support block 12, and the upper side of the drone platform support block 12 is fixedly connected to the drone support platform 1;
[0023] The connecting rod 2 11 and the connecting rod 1 2 are connected to the buffer assembly.
[0024] In this embodiment, when the drone lands on the drone support platform 1, due to the action of gravity, the connecting rod 1 2 and the connecting rod 2 11 swing, the support block 17 moves, and the buffer assembly buffers the force applied to the drone support platform 1, thereby achieving the stability of the connecting rod 1 2 and the connecting rod 2 11.
[0025] The buffer assembly includes a sleeve 6, and the lower ends of the sleeves 6 are hinged on both sides of the connecting rod 2 11. The round rod of the connecting rod 3 is inserted into each of the sleeves 6. The outer end hinge block of each connecting rod 3 is hinged to the corresponding connecting rod 1 2. Each of the sleeves 6 fixes one end of the spring 1 4, and the other end of each spring 1 4 is fixedly connected to the outer end hinge block of the connecting rod 3. Each spring 1 4 is respectively sleeved around the corresponding sleeve 6 and the round rod of the connecting rod 3.
[0026] When the UAV support platform 1 is parallel to the ground, the angle between the axis of the sleeve 6 and the ground is 30 degrees.
[0027] In this embodiment, the connecting rod 1 swings to drive the connecting rod 3 to move, the connecting rod 3 moves along the sleeve 6 and drives the sleeve 6 to swing, and the spring 1 4 produces elastic deformation to achieve a buffering function.
[0028] One side of the connecting rod 11 is fixedly connected to a fixed shaft 16, and the fixed shaft 16 is hingedly connected to the outer end of the moving rod 15. The round axis of the moving rod 15 is inserted into the limiting cylinder 13, and the lower end of the limiting cylinder 13 is hinged to a limiting block 8, and the limiting block 8 fixes the base 7.

[0030] In this embodiment, the other end of the connecting rod 2 11 realizes the support and shock-absorbing and buffering functions through a buffer support assembly composed of a limit cylinder 13, a movable rod 15 and a spring 2 14. When the connecting rod 1 2 and the connecting rod 2 11 swing downward, the spring 2 14 undergoes elastic deformation, and the movable rod 15 moves in the limit cylinder 13 to realize the buffering and shock-absorbing function.
[0031] During use, the UAV lands on the UAV support platform 1. Due to the action of gravity, the connecting rod 2 swings downward, and the connecting rod 2 drives the connecting rod 11 to swing through the support block 17. The connecting rod 11 drives the moving rod 15 to move in the limit cylinder 13, and the spring 2 14 undergoes elastic deformation. At the same time, the connecting rod 2 drives the connecting rod 3 to move, and the connecting rod 3 moves along the sleeve 6 and drives the sleeve 6 to swing. The spring 1 4 produces elastic deformation. The elastic deformation of the spring 1 4 and the spring 2 14 buffers the vibration force and gravity, thereby realizing the shock absorption function.
