[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0017] Combination Figure 1-3 As shown, the UAV includes a frame 1, a fixed frame 3 is provided in the frame, a pair of oppositely arranged fixed sleeves 4 are rotatably provided in the fixed frame, each fixed sleeve 4 is provided with a main rod 5 facing outward, a connecting rod 7 is transversely provided at the bottom of the main rod 5 through a connecting sleeve 6, supporting feet 8 are provided at both ends of the connecting rod 7, a propeller assembly 9 is provided on the top of the supporting foot 8, a guide rod 10 is provided between the two fixed sleeves 4 in the fixed frame, a guide sleeve 11 is provided on the guide rod 10, a pair of pull blocks 12 are rotatably provided on the guide sleeve 11, the pull blocks 12 are respectively rotatably connected to the fixed sleeves 4 on the same side, and a spring 13 is provided on the guide rod 10 between the guide sleeve 11 and the fixed frame 3.
[0018] The frame is the main carrier of the entire drone. Two cavities are formed in the frame 1, one of which is used to install the power supply assembly 2, and the other cavity is provided with a fixing frame 3. The power supply assembly provides power for the flight of the entire drone. Placing the power supply assembly alone in the cavity can effectively avoid interference from other components. The power supply assembly provides a power source to the propeller assembly. Under the action of the propeller assembly, the drone performs flight actions. Since the propeller assembly is not the focus of this device, it will not be described here.
[0019] After the drone has finished flying and landed at the designated location. First, the support feet come into contact with the ground. Under the action of gravity, the two fixed sleeves will rotate slightly upward. At this time, under the pull of the pull block, the guide sleeve will move a short distance upward along the guide rod, and the spring will be compressed under the push of the guide sleeve. Until the drone lands smoothly at the designated location, the spring will recover its deformation, and the guide sleeve will reset under the action of the spring. During the entire descent of the drone, the spring can buffer the drone and allow it to stably complete the descent action, which can make the drone safer during take-off and landing.
[0020] In this structure, the support foot 8 includes a sleeve 81 installed on the connecting rod 7, and the bottom of the sleeve is respectively provided with a support foot 82 and a support rod 83 from the outside to the inside, and the bottom of the support rod 83 is installed to the middle of the support foot. The sleeve serves as the support foot installation body, and the top of the sleeve is provided with a propeller assembly, and the bottom is respectively provided with a support foot and a support rod. The bottom of the support foot is bent inward to form a support block, and the support rod supports the support foot. Under the action of the support rod, the support foot is more reliable and strong.
[0021] Further as a preferred structure, Figure 1 The bottom of the front end of the frame 1 is connected to a stand frame 18, and a shallow groove (blocked in the figure) is opened at the front end of the stand frame 18. The upper and lower ends of the stand frame 18 are formed with internal threaded columns 19, and a matching visual element 20 is arranged in the shallow groove. The drone also includes a block 21, and locking screws 22 are respectively inserted into the two ends of the block. The locking screws are screwed into the internal threaded column 19 to lock the visual element.
[0022] During the use of the drone, the visual element is used as a tool for shooting and recording. The visual element is covered with a protective shell. When it is to be installed on the stand of the drone, the visual element is first placed in the shallow groove as required, and then the block is taken out. The block is placed opposite to the internal thread column, and then the locking screw is inserted into the block. After the locking screw is screwed into the corresponding internal thread column, the visual element is fixed on the stand.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
