[0021] Reference Figure 1-Figure 4 A UAV tripod includes a frame 1, which is welded from an aluminum alloy material in the prior art, and the specific specifications and models are customized according to the specifications of the assembled UAV, which can maximize the adaptability of the UAV. An assembly hole 2 is opened at the mounting position of the frame 1, and will not affect the normal use of other components. The assembly hole 2 is a reserved fixing position, and is concentratedly opened according to the hole position and the fixing position at the bottom of the UAV. The assembly bar 3 is an extension component of the frame 1, and its material is the same as the frame 1, both of which are aluminum alloy. The function of the assembly bar 3 is mainly to limit the buffer support component of the frame 1.

[0022] An elastic bag 5 for reducing the impact effect is provided on the assembly bar 3. The elastic bag 5 is elliptical and buried between the assembly bar 3 and the first alloy rod 4. It is mainly used to alleviate the impact of the first alloy rod 4 when it is subjected to impact force, thereby indirectly increasing the service life of the assembly bar 3. The assembly bar 3 is fixedly connected to the side wall of the frame 1 by welding, and welding can increase the connection strength between the two. The assembly bar 3 is symmetrically provided with a first alloy rod 4 for transmitting impact force. After the frame 1 contacts the ground, the first alloy rod 4 generates an impact force transmission component, which is transmitted through multiple components to concentrate and disperse the impact force, thereby maximizing the stability of the frame 1 and the drone, and the first alloy rod 4 is against the elastic bag 5, and the outer side of the first alloy rod 4 is tightly pressed against the elastic bag 5, and is only in contact and pressed against the elastic bag 5 when the first alloy rod 4 floats. One end of the first alloy rod 4 passes through the assembly bar 3, and the other end of the first alloy rod 4 passes through the assembly bar 3, so that it is fixed in the assembly bar 3 as a whole.

[0023] The assembly strip 3 is symmetrically provided with a second alloy rod 7 for transmitting impact force. The second alloy rod 7 is arranged on the first alloy rod 4, and their functions are both impact force transmitting components, and secondly impact force dispersing components. The second alloy rod 7 is C-shaped, and the C-shape can improve the wrapping of the first alloy rod 4, and can quickly transmit the impact force to the first alloy rod 4, and the inner wall is against one end of the first alloy rod 4 through a buffer body 6. The buffer body 6 is a prior art, and it is made of rubber and other materials with good buffering. Its function is to reduce the damage of the impact force of the second alloy rod 7 to the first alloy rod 4. The outer wall of the second alloy rod 7 is against the assembly strip 3, and the outer wall of the second alloy rod 7 is beveled, which can avoid the second alloy rod 7 from causing fatal damage to the assembly strip 3 when it floats.

[0024] The second alloy rod 7 is provided with a plurality of elastic shafts 8 for absorbing impact force. The elastic shafts 8 are mainly used to assist in dispersing impact. The elastic shafts 8 are linearly arranged on the second alloy rod 7, and their number is arranged according to the length of the second alloy rod 7. The elastic shafts 8 are provided with compression springs for improving the absorption efficiency. The compression springs are prior art. One end of the elastic shaft 8 is fixedly connected to the assembly bar 3, which can reduce the damage of the impact force to the assembly bar 3.

[0025] The second alloy rod 7 is provided with a hydraulic column 10 for improving the descent stability of the UAV. The hydraulic column 10 is a prior art and is mainly used to improve the landing stability of the UAV and avoid unnecessary bumps. The hydraulic column 10 is fixedly connected to the second alloy rod 7 through a connector 9. The connector 9 is an auxiliary connecting component in the prior art, and the connector 9 is fixedly connected to the first alloy rod 4 and the second alloy rod 7 by welding. Welding can improve the connection strength between the two.

[0026] The hydraulic column 10 is provided with a plurality of supporting legs 13 for contacting the rugged ground. The supporting legs 13 are all in the shape of curved strips, which can maximize the contact area of ​​the frame 1. At the same time, a rubber surface can be set at the middle end of the supporting legs 13 to further reduce the impact force. The hydraulic column 10 is provided with a hydraulic rod 11 for transmitting force. The hydraulic rod 11 is a prior art and can be extended and retracted into the hydraulic column 10 through downward pressure. The hydraulic rod 11 is provided with a centralizing plate 12 for fixing the supporting legs 13. The centralizing plate 12 is used to centrally fix the supporting legs 13, and the centralizing plate 12 is fixedly connected to the hydraulic rod 11 through ball bearings. The ball bearings are prior art and can provide the supporting legs 13 with a small angle adjustment to adapt to different terrains. The supporting legs 13 are fixedly connected to the centralizing plate 12 through fasteners, and the fasteners are auxiliary connecting components.

[0027] The working principle of the utility model is as follows: the frame 1 is assembled with the drone by screws, and then when the drone lands, the support legs 13 uniformly transmit the received impact force to the hydraulic column 10. The hydraulic column 10 will float up and down when impacted, and the floating effect will immediately drive the floating of the second alloy rod 7. The floating of the second alloy rod 7 can disperse part of the impact force until the remaining impact force is dispersed by the first alloy rod 4.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
