Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an anti-collision structure for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles, also known as drones, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. With the development of science and technology, drones are widely used in various environments. Existing drones are generally equipped with obstacle avoidance functions, so drones do not have corresponding anti-collision mechanisms when in use, or only have wing protection mechanisms. Although this is no problem in normal use, it cannot be well protected when the drone is conducting aerial surveys. In this way, once a collision occurs during the test, it is not only prone to damage, but also prone to imbalance after the collision.

[0003] Announcement No. CN 218786091 U discloses an anti-collision mechanism for an aerial survey UAV. When used in aerial surveys, an anti-collision frame can be flexibly installed on the landing gear, so that the upper end of the UAV can be protected by the anti-collision frame. At the same time, the protection effect of the side of the UAV can be increased by the balance frame, and the advantage of increasing the balance performance of the UAV can be achieved. It is also convenient for personnel to use the anti-collision frame as a temporary handle for carrying and moving during aerial surveys. However, the patent still has the following problems in actual use:

[0004] Although the anti-collision mechanism of the aerial survey UAV installs an anti-collision frame on the landing gear to protect the upper end of the UAV through the anti-collision frame, and increases the protection effect of the side of the UAV through the balance frame, the landing gear cannot be adjusted. When there are stones or obstacles on the landing ground, the landing gear cannot effectively clear or avoid the obstacles, thereby affecting the landing stability of the UAV. The anti-collision frame is relatively hard in texture. Although it can effectively protect the UAV when a collision occurs, the impact force will be transmitted to the inside of the UAV, causing damage to the internal parts of the UAV.

[0005] Therefore, a UAV anti-collision structure is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide an anti-collision structure for a UAV to solve the problem that the anti-collision mechanism for the aerial survey UAV proposed in the above-mentioned background technology can protect the upper end of the UAV by installing an anti-collision frame on the landing gear, and increase the protection effect of the side of the UAV by a balance frame, but the landing gear cannot be adjusted. When there are stones or obstacles on the landing ground, the landing gear cannot effectively clear or avoid the obstacles, thereby affecting the landing stability of the UAV. The anti-collision frame is relatively hard in texture. Although it can effectively play a protective role when the UAV collides, the impact force will be transmitted to the inside of the UAV, thereby causing damage to the internal parts of the UAV.

[0022] 1. By setting up the landing protection mechanism, not only can the elastic force of the first buffer spring be utilized to make the moving roller contact the ground first when the UAV lands, and drive the second supporting rotating rod to squeeze the transverse moving bracket, under the action of the sliding connection between the transverse sliding sleeve and the transverse sliding rod, the first supporting rotating rod rotates and drives the transverse sliding sleeve to squeeze the second buffer spring, so that the transverse sliding sleeve drives the second rotating support and the second supporting rotating rod to move relative to each other, and under the action of the sliding connection between the buffer sliding rod and the buffer sliding sleeve, the third supporting rotating rod rotates and drives the buffer sliding sleeve to squeeze the third buffer spring, thereby realizing the rotation of the second supporting rotating rod.

The elastic force of the first buffer spring, the second buffer spring, the third buffer spring and the fourth buffer spring can effectively reduce the impact force between the drone and the ground when it lands, thereby achieving an anti-collision effect.

The fixing knob drives the fixing bolt to rotate, so that the fixing pressure plate moves outside the fixing bolt, and the camera body can be pressed, which is convenient for installation and disassembly of the camera body. The landing bracket, the supporting connecting rod and the landing bottom plate can be used to provide secondary support for the UAV, and the landing stability of the UAV can be further improved.

[0023] 2.

[0042] Secondly, by utilizing the elastic force of the first buffer spring 107, when the drone lands, the moving roller 123 first contacts the ground, and drives the second supporting rotating rod 116 to squeeze the transverse moving bracket 108. Under the action of the sliding connection between the transverse sliding sleeve 111 and the transverse sliding rod 110, the first supporting rotating rod 112 rotates and drives the transverse sliding sleeve 111 to squeeze the second buffer spring 114, so that the transverse sliding sleeve 111 drives the second rotating support 115 and the second supporting rotating rod 116 to move relative to each other. 19, the third support rotating rod 121 can be rotated and the buffer sliding sleeve 119 can be driven to squeeze the third buffer spring 120, so as to realize the rotation adjustment of the second support rotating rod 116, which can adapt to roads with different slopes, enable the UAV to automatically adjust the level, and improve the landing stability of the UAV. When the moving roller 123 rotates outward, the main rotating gear 124 is driven to rotate.

When the cleaning scraper 134 needs to be replaced, the meshing rack 130 is driven to move by pressing the unlocking button 132. The meshing connection between the meshing rack 130 and the mounting gear 129 can be used to move the mounting pin 131 to the inside of the mounting box 128, and the cleaning scraper 134 can be quickly taken out of the mounting slot 127 for easy installation. The cleaning scraper 134 can be quickly replaced. When the ground where the UAV lands has stones that are stuck in the mud and cannot move, the third buffer spring 120 is used to rotate the second supporting rotating rod 116, and the entire UAV can be translated to one side, so that the UAV can automatically avoid obstacles and further protect the UAV. The elastic force of the first buffer spring 107, the second buffer spring 114, the third buffer spring 120 and the fourth buffer spring 122 can effectively reduce the impact force between the UAV and the ground when landing, thereby achieving an anti-collision effect.

[0043] Finally, by rotating the motor 136 to drive the rotating connecting shaft 137 and the rotating disk 138 to rotate, the camera body 149 can be flipped to the inner side of the camera bracket 135, so as to protect the camera body 149, and by the clamping motor 141 to drive the first sprocket transmission assembly 142 and the clamping two-way threaded rod 143 to rotate, the clamping threaded sleeve 144 drives the fixed bracket 145 to move relatively, so as to preliminarily limit the camera body 149, and by rotating the fixing knob 146 to drive the fixing bolt 147 to rotate, the fixing pressure plate 148 moves on the outside of the fixing bolt 147, so as to press the camera body 149, and facilitate the installation and disassembly of the camera body 149, and the landing bracket 103, the supporting connecting rod 104 and the landing base plate 105 can be used to provide secondary support to the UAV, thereby further improving the landing stability of the UAV.
