In the utility model, by providing a buffer device, when the drone is controlled to stop flying, the support rod will first contact the ground, and the support rod will be forced to move toward the inside of the sleeve, the movement of the support rod toward the inside of the sleeve drives the cross plate to move, the movement of the cross plate drives the hinged plate to move, the movement of the hinged plate pushes the two sliders to move away from each other on the surface of the slide rod, the movement of the two sliders on the surface of the slide rod away from each other will drive the first spring to stretch, and then the resilience of the first spring is used to reduce the impact force of the ground on the fuselage during landing. Through the cooperation of the above structure, the device can reduce the possibility of the drone rolling over when it is stopped and protect the fuselage body at the same time.

[0013] 2. In the utility model, a limit device is provided. When the elastic potential energy of the buffer device is weakened after long-term use and needs to be replaced, the pull rod is pulled first. The movement of the pull rod drives the cross plate to move on the surface of the extension rod. The movement of the cross plate on the surface of the extension rod squeezes the second spring, causing the second spring to be compressed. At the same time, the movement of the cross plate on the surface of the extension rod also drives the insertion rod to move. The movement of the insertion rod causes it to move out from the inside of the socket. The separation of the insertion rod and the socket causes the sleeve to lose the limit in the inside of the mounting seat. At this time, the sleeve can be removed from the inside of the mounting seat to complete the corresponding disassembly operation. Through the cooperation of the above-mentioned structure, the buffer device can be replaced in time when it needs maintenance in the later stage, thereby further improving the practicality of the device.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] See also Figure 1-4 The utility model provides a technical solution: a geographical terrain surveying and mapping UAV, comprising a fuselage body 1, and wings 2 are fixedly installed at the four corners of the fuselage body 1.

[0023] The specific arrangement and function of the buffer device 3 and the limit device 4 will be described in detail below.

[0024] In this embodiment: a buffer device 3 is provided on the bottom surface of the fuselage body 1, and the buffer device 3 includes four mounting seats 31, and the four mounting seats 31 are fixedly installed on the bottom surface of the fuselage body 1, and sleeves 32 are movably installed inside the four mounting seats 31, and a support rod 33 is slidably connected inside the sleeve 32.

[0025] In this embodiment, the arrangement of the support rod 33 and the sleeve 32 has the effect of supporting the fuselage body 1 .

[0026] Specifically, a slide bar 34 is fixedly installed between every two sleeves 32 , two sliders 35 are slidably connected to the surface of the slide bar 34 , and a first spring 36 is fixedly installed between the two sliders 35 .

[0027] In this embodiment, the first spring 36 is provided to limit the position of the slider 35 on the surface of the slide rod 34 .

[0028] Specifically, a horizontal plate 38 is fixedly installed between each two support rods 33, and two hinge plates 37 are hinged on the surface of the horizontal plate 38, and one end of the hinge plate 37 away from the horizontal plate 38 is hinged to the slider 35. The setting of the hinge plate 37 has the effect of driving the slider 35 to move on the surface of the slide rod 34.

[0029] In this embodiment: the outer wall surfaces of the four mounting seats 31 are each provided with a limiting device 4, the limiting device 4 includes an extension rod 41, the extension rod 41 is fixedly installed on the outer wall surfaces of the four mounting seats 31, and a horizontal strip 42 is slidably connected between every two extension rods 41, and a pull rod 43 is fixedly installed on the surface of the horizontal strip 42. When the elastic potential energy of the buffer device 3 is weakened after long-term use and needs to be replaced, first pull the pull rod 43. The movement of the pull rod 43 drives the cross plate 42 to move on the surface of the extension rod 41. The movement of the cross plate 42 on the surface of the extension rod 41 will squeeze the second spring 47, so that the second spring 47 is compressed. At the same time, the movement of the cross plate 42 on the surface of the extension rod 41 also drives the insertion rod 44 to move. The movement of the insertion rod 44 causes itself to move out from the inside of the socket 45. The separation of the insertion rod 44 and the socket 45 causes the sleeve 32 to lose its limit in the inside of the mounting seat 31. At this time, the sleeve 32 can be removed from the inside of the mounting seat 31 to complete the corresponding disassembly operation. Through the cooperation of the above-mentioned structure, the buffer device 3 can be replaced in time when it needs maintenance in the later stage, thereby further improving the practicality of the device.

[0030] Specifically, two insertion rods 44 are fixedly mounted on the surface of the horizontal strip plate 42 , and an insertion hole 45 is formed on the outer wall surface of each sleeve 32 .

[0031] In this embodiment, the provision of the insertion rod 44 and the insertion hole 45 has the effect of limiting the sleeve 32 inside the mounting seat 31 .

[0032] Specifically, a limiting plate 46 is fixedly mounted on the end surface of each extension rod 41 away from the mounting seat 31 , and a second spring 47 is fixedly mounted between the limiting plate 46 and the horizontal strip plate 42 .

[0033] In this embodiment, the second spring 47 is provided to limit the position of the horizontal strip 42 on the surface of the extension rod 41 .

[0034] Working principle: by setting the buffer device 3, when the drone is controlled to stop flying, the support rod 33 will first contact the ground, and the support rod 33 will move toward the inside of the sleeve under the force, and the support rod 33 will move toward the inside of the sleeve 32 to drive the cross plate 38 to move, and the movement of the cross plate 38 will drive the hinged plate 37 to move, and the movement of the hinged plate 37 will push the two sliders 35 to move away from each other on the surface of the slide bar 34, and the movement of the two sliders 35 on the surface of the slide bar 34 to move away from each other will drive the first spring 36 to stretch, and then the resilience of the first spring 36 is used to reduce the impact force of the ground on the fuselage during landing. Through the cooperation of the above structure, the device can reduce the possibility of the drone rolling over when it is stopped and protect the fuselage body 1 at the same time. When the elastic potential energy of the buffer device 3 is weakened after long-term use and needs to be replaced, first pull the pull rod 43. The movement of the pull rod 43 drives the cross plate 42 to move on the surface of the extension rod 41. The movement of the cross plate 42 on the surface of the extension rod 41 will squeeze the second spring 47, so that the second spring 47 is compressed. At the same time, the movement of the cross plate 42 on the surface of the extension rod 41 also drives the insertion rod 44 to move. The movement of the insertion rod 44 causes itself to move out from the inside of the socket 45. The separation of the insertion rod 44 and the socket 45 causes the sleeve 32 to lose its limit in the inside of the mounting seat 31. At this time, the sleeve 32 can be removed from the inside of the mounting seat 31 to complete the corresponding disassembly operation. Through the cooperation of the above-mentioned structure, the buffer device 3 can be replaced in time when it needs maintenance in the later stage, thereby further improving the practicality of the device.
