[0009] The buffer mechanism is arranged on the two sets of supporting legs. The buffer mechanism is used to achieve buffering of the drone and adjust the buffering state. The buffer mechanism includes a groove, a rotating bar and a positioning assembly. A set of grooves is opened on each of the two sets of supporting legs. A set of rotating bars is rotatably installed between the front and rear inner walls of the two sets of grooves. A set of positioning assemblies is provided on the front side of each of the two sets of supporting legs.

[0010] Preferably, the positioning assembly includes a connecting plate, an insertion rod, a return spring and a pull block.

Two groups of guide rods are fixedly installed on the top of the two groups of buffer plates. One end of the two groups of guide rods passes through the bottom of the corresponding rotating bar and extends to the interior of the corresponding rotating bar. Two groups of dampers are fixedly installed between the top of the two groups of buffer plates and the bottom of the corresponding rotating bar.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The buffer structure of a drone provided in this embodiment is shown in Figures 1 to 3, including a drone body 1, two sets of support legs 2 are fixedly installed at the bottom of the drone body 1, and a buffer mechanism 3 is arranged on the two sets of support legs 2. The buffer mechanism 3 is used to realize the buffering of the drone and adjust the buffering state. The buffer mechanism 3 includes a groove 31, a rotating bar 32 and a positioning component 37. A group of grooves 31 are opened on the two sets of support legs 2, and a group of rotating bars 32 are rotatably installed between the front and rear inner walls of the two sets of grooves 31. A group of positioning components 37 are provided on the front sides of the two sets of support legs 2. The bottom of the drone body 1 is fixedly installed. There is a camera 4, and two groups of lighting lights 5 are fixedly installed on the bottom of the drone body 1. The two groups of lighting lights 5 are located on both sides of the camera 4. At least two groups of indicator lights 6 are fixedly installed on the outer surfaces of both sides of the drone body 1. Two groups of rubber pads 7 are fixedly installed on the bottom of the two groups of supporting legs 2. Through the camera 4, the drone can be used for shooting and field of view transmission when in use, so that the user can control the flight. At the same time, under the action of the lighting lights 5 and the indicator lights 6, the clarity of the flight field can be improved when flying at night, and the position of the drone can be easily obtained, which ensures the use effect of the structure and is conducive to the promotion and use of the structure.

[0028] The positioning assembly 37 includes a connecting plate 371, an insertion rod 372, a return spring 373 and a pull block 374. The front outer surfaces of the two groups of rotating bars 32 are each provided with two groups of slots, and the front sides of the two groups of supporting legs 2 are each provided with a group of connecting plates 371. The rear outer surfaces of the two groups of connecting plates 371 are each fixedly installed with two groups of insertion rods 372. The four groups of insertion rods 372 all pass through the corresponding supporting legs 2 and extend into the corresponding grooves 31, and one end of one group of insertion rods 372 on the two groups of connecting plates 371 extends into the corresponding slot. A group of return springs 373 are fixedly connected between the rear outer surfaces of the two groups of connecting plates 371 and the front outer surfaces of the corresponding supporting legs 2, and a group of pull blocks 374 are fixedly installed on the front outer surfaces of the two groups of connecting plates 371.

[0029] The buffer mechanism 3 also includes a buffer plate 33, a guide rod 34, a damper 35 and a buffer spring 36. A group of buffer plates 33 are provided directly below the two groups of rotating bars 32. Two groups of guide rods 34 are fixedly installed on the tops of the two groups of buffer plates 33. One end of the two groups of guide rods 34 passes through the bottom of the corresponding rotating bar 32 and extends to the inside of the corresponding rotating bar 32. Two groups of dampers 35 are fixedly installed between the tops of the two groups of buffer plates 33 and the bottoms of the corresponding rotating bars 32. A group of buffer springs 36 are sleeved on the two groups of dampers 35. Through the buffer mechanism 3 As well as the positioning component 37 thereon, when the drone is in use, the damper 35 and the buffer spring 36 can cooperate to provide a buffer when the drone lands to protect the drone. When the drone is not in use, the buffer plate 33 can be retracted so that the support leg 2 can stably support the drone for placement. This solves the problem that some existing drones are still supported by springs when not in use, and cannot be placed stably by relying solely on spring support, and are prone to shaking or even falling. Removing the spring is inconvenient for next use and is time-consuming and labor-intensive, thereby improving the practicality of the structure.

[0030] Working principle: When the drone is in use, especially when it lands, it first contacts the ground through the two sets of buffer plates 33, and the two sets of buffer plates 33 then compress the buffer springs 36, and release the kinetic energy into thermal energy buffering through the dampers 35 to ensure the safe landing of the drone. When the drone is not in use and idle, the two sets of pull blocks 374 are pulled to drive the various plug rods 372 on the two sets of connecting plates 371 to move outward and stretch the two sets of return springs 373, so that the plug rods 372 originally inserted in the corresponding slots on the two sets of rotating bars 32 are disengaged. At this time, the two sets of rotating bars 32 are rotated to make the two sets of buffer plates 33 flip up, and then the two sets of pull blocks 374 are released. Under the rebound action of the two sets of return springs 373, the plug rods 372 are reset, and the two sets of plug rods 372, which are different from the original corresponding ones, are inserted into the slots on the two sets of rotating bars 32 in this state, fixing the two sets of flipped rotating bars 32. At this time, the drone is stably placed by the two sets of supporting legs 2.

[0031] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be understood as limiting the present invention.
