[0001] This application relates to the technical field of unmanned aerial vehicles, and in particular to a collision protection structure for an unmanned aerial vehicle. Background Art
[0002] An unmanned aerial vehicle, abbreviated as "UAV" and with the English abbreviation "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, or is operated completely or intermittently autonomously by an on - vehicle computer. Currently, UAV technology has been widely applied, and UAVs can replace humans in performing some tasks that are difficult or dangerous for humans.
[0003] To avoid damage to the UAV when it collides with a location during recovery, some existing UAVs are equipped with spring buffer components on their support legs. However, after long - term use, the springs will rust due to aging, reducing their original elasticity. When replacing them, the staff needs to replace the support legs together, increasing the replacement cost and making it inconvenient for normal use. Utility Model Content

Detailed Description of the Embodiment
[0019] The following further describes the present application in detail with reference to the Figures 1 - 3 drawings.
[0020] The embodiment of the present application discloses a collision protection structure for a drone. Refer to Figures 1 - 3, a collision protection structure for a drone, comprising a drone body 1, on which a support leg rod 2 is fixed, and screw joints 6 are arranged at both ends of the support leg rod 2; further comprising a buffer mechanism, a screw sleeve 5 is screwed onto the screw joint 6, and the buffer mechanism is installed on the screw sleeve 5 for buffering and shock-absorbing the drone body 1. The buffer mechanism includes an insertion rod 8 sleeved on the screw sleeve 5, the insertion rod 8 is slidably connected to the screw sleeve 5, a fixed block 4 is fixed at the protruding end of the insertion rod 8, a fixed column 10 is sleeved on the fixed block 4, and the fixed column 10 is slidably connected to the fixed block 4. The insertion rod 8 and the screw sleeve 5 are slidably connected. Therefore, the screw sleeve 5 can rotate freely on the insertion rod 8. During installation, only by aligning and screwing the screw sleeve 5 clockwise can the buffer mechanism be installed on the support leg rod 2, which is convenient for operation. Through the design of the screw sleeve 5, it is also unnecessary to use tools during the installation process, and the staff can operate with their hands, improving the practicality and facilitating subsequent maintenance.
[0021] In this embodiment, as Figure 3 shown, a support foot pad 3 is fixed at the bottom end of the fixed column 10. Further comprising a buffer spring 12, the buffer spring 12 is sleeved outside the fixed column 10 and is respectively connected to the fixed block 4 and the support foot pad 3. When the drone body 1 lands, first, the support foot pad 3 contacts the ground, and the collision force will be transmitted to the fixed column 10, causing the fixed column 10 to move upward. At this time, the support foot pad 3 squeezes the buffer spring 12, and part of the collision force will be transmitted to the buffer spring 12, so as to slow down the force through the characteristics of the buffer spring 12 itself, thereby realizing the function of buffering and anti-collision.
[0022] In this embodiment, as Figure 3 shown, a screw joint 6 is also arranged at the top end of the fixed column 10, and a nut 11 is screwed onto the screw joint 6. When the buffer spring 12 is damaged or cannot play a normal buffering role, unscrew and remove the nut 11, and pull out the fixed column 10 to replace it, reducing the cumbersome steps of traditional overall replacement and lowering the replacement cost.
[0023] In this embodiment, as Figure 3 shown, an insertion slot 7 is opened on the end face of the support leg rod 2, and the insertion rod 8 is adapted to the insertion slot 7. This setting further improves the installation stability of the buffer anti-collision mechanism and improves the practicality.
[0024] In this embodiment, as Figure 3 shown, a positioning piece 9 is fixed on the insertion rod 8, and the positioning piece 9 can be connected to the support leg rod 2. When the insertion rod 8 is inserted into the insertion slot 7, the positioning piece 9 fits against the end face of the support leg rod 2, playing a limiting role.
[0025] In this embodiment, as Figure 3As shown, a chamfer is provided at the notch of the insertion slot 7. The chamfer enables the insertion rod 8 to be inserted into the insertion slot 7 more smoothly, facilitating the installation operation and having practicality.
[0026] The implementation principle of a drone collision protection structure according to an embodiment of the present application is as follows: During installation, only need to align the insertion rod 8 and insert it into the insertion slot 7. At this time, the screwed sleeve 5 is sleeved on the support leg rod 2, and by clockwise screwing the screwed sleeve 5, the buffer mechanism can be installed on the support leg rod 2. The operation is convenient. Through the design of the screwed sleeve 5, it is also unnecessary to use tools during the installation process, and the staff can operate with their hands, improving the practicality and facilitating subsequent maintenance. When the buffer spring 12 is damaged or cannot play a normal buffering role, unscrew and remove the nut 11, and pull out the fixed column 10 to replace it, reducing the cumbersome steps of traditional overall replacement and reducing the replacement cost. By providing the screwed sleeve 5 and the screwed joint 6, it is convenient for the installation and disassembly of the buffer mechanism, which helps the assembly of the drone. By providing the fixed block 4, the fixed column 10 and the nut 11, after long-term use, when the buffer spring 12 is damaged, it can be replaced separately, avoiding traditional overall replacement, reducing the replacement cost, and the installation and disassembly are both relatively convenient. Moreover, by providing the insertion rod 8 and the insertion slot 7, the installation stability of the buffer and anti-collision mechanism is further improved, and the practicality is enhanced.
