It is controlled by a radio remote control device or an autonomous program control device. It has multiple functions such as aerial flight, mission payload, ground control, etc. At this stage, in order for operators to take timely measures to avoid damage or accidents when starting and stopping the drone, distance sensors are installed on the drone for early warning.
[0003] According to the Chinese patent publication number CN219257745U, "A disaster warning drone with a shock-absorbing structure", it mainly describes that through the installation of a shock-absorbing mechanism, the shock absorber can alleviate the impact force caused by severe bumps on the drone body, and the spring can reduce the impact force generated when the drone body falls, which can better protect the disaster warning drone and increase its service life. In this process, the drone starts and stops at different positions. Using a single distance sensor for monitoring will cause the drone body to deviate when it lands, resulting in impact damage.
[0004] Therefore, a UAV with an impact warning structure is proposed to solve the problem that during this process, the UAV starts and stops at different positions, and using a single distance sensor for monitoring will cause the UAV body to deviate when it lands, resulting in impact damage. Utility Model Content

[0007] As a preferred technical solution of the utility model, a spring rod is fixedly connected to the upper end of the pad, a fixing sleeve is sleeved on the spring rod and the fixing sleeve is fixedly connected to the bottom side of the drone body. By arranging the spring rod and the fixing sleeve, the pad can be stably limited on the bottom side of the drone body.

By providing the sleeve rod, the position of the contact block can be limited, which is convenient for replacement.
[0009] As a preferred technical solution of the utility model, a limit rod is inserted on the rotating rod, and the limit rod is in contact with the rotating bar. By providing the limit rod, the contact block can be replaced during disassembly.
[0010] As a preferred technical solution of the utility model, a support ball is rotatably embedded on the rotating bar, and the support ball contacts the contact block. The friction between the rotating bar and the contact block is reduced by providing the support ball.
[0011] The utility model has the following advantages: by installing connecting blocks and distance sensors on the four sides of the pad, the distance between the drone and the ground is monitored when the drone is landing, and the operator is reminded to make adjustments so that the drone can rise and fall directly. Then, when the pad contacts the ground, force is applied to the plug rod and the baffle plate to squeeze the first spring and the spring rod, forming a double buffering effect, which increases and decreases the deviation of the drone when it lands, thereby reducing impact damage.

DETAILED DESCRIPTION
[0016] The utility model will be further described below in conjunction with the accompanying drawings.
[0017] Please refer to Figure 1-3 The drone with an impact warning structure shown in the figure comprises a drone body 1, both sides of the bottom end of the drone body 1 are fixedly connected with convex strips 2, both ends of the convex strips 2 are rotatably connected with rotating strips 3 through rotating shafts, a rotating rod 4 is inserted into the bottom side of the rotating strip 3, a contact block 5 is sleeved on the rotating rod 4, a connecting sleeve 6 is arranged between the two contact blocks 5, a plug rod 7 is welded on one side of the connecting sleeve 6, and a pad 8 is arranged between the four plug rods 7. When the pad 8 and the contact block 5 are subjected to force, the spring rod 14 is squeezed and shrinks, and the plug rod 7 moves to the side away from the pad 8, so that the baffle 10 squeezes the first spring 11 , and provide reverse force, so that the impact force of the drone falling to the ground is reduced, a limit slot 9 is provided on the pad 8 and the plug rod 7 is inserted into the limit slot 9, the plug rod 7 is located in the limit slot 9 and is fixedly connected with a baffle 10, and the baffle 10 contacts with a first spring 11, and the first spring 11 is sleeved on the plug rod 7, and the four sides of the pad 8 that are far away from each other are fixedly connected with connecting blocks 12, and the bottom side of the connecting block 12 is fixedly connected with a distance sensor 13. The four distance sensors 13 provide distance monitoring, which can remind the staff to make adjustments, so that the drone body 1 can land smoothly, provide early warning and reduce impact.
[0018] Among them, the bottom side of the drone body 1 is fixedly connected to the fixing sleeve 15, the fixing sleeve 15 is sleeved with the spring rod 14, and the spring rod 14 is fixedly connected to the upper end of the pad 8. By arranging the spring rod 14 and the fixing sleeve 15, the pad 8 can be stably limited on the bottom side of the drone body 1.
[0019] The connecting sleeve 6 is rotatably connected to the sleeve rod 17 through a bearing. The sleeve rod 17 is integrally formed with the rotating rod 4 by casting. By providing the sleeve rod 17, a larger diameter than the rotating rod 4 can be used to provide a limit for the contact block 5.
[0020] The rotating bar 3 contacts the limiting rod 16, and the limiting rod 16 is inserted into the rotating rod 4. By providing the limiting rod 16, the rotating bar 3 can be stuck on the rotating rod 4, so that the contact block 5 can be replaced during disassembly.
[0021] The contact block 5 contacts the supporting ball 18 , and the supporting ball 18 is rotatably embedded in the rotating bar 3 . By providing the supporting ball 18 , the rotational friction between the rotating bar 3 and the contact block 5 is reduced.
[0022] Working principle: When the drone body 1 is landing, the four distance sensors 13 can be used to monitor the ground and remind the staff to control the drone body 1 until the four sides are parallel to the ground, and then continue to control the drone body 1 to move downward, which can greatly improve the accuracy of the drone's impact warning. At this time, the pad 8 contacts the ground and transmits pressure to the spring rod 14, causing the spring rod 14 to contract. At this time, the two corresponding rotating bars 3 move outward, and the contact block 5 rotates, while causing the rotating rod 4 to pull the connecting sleeve 6 and the plug 7. At this time, the baffle 10 moves synchronously, and the first spring 11 contracts. The spring rod 14 cooperates with the first spring 11 to provide buffering, which can greatly improve the buffering effect of the drone.
