Conventional protective covers can only provide a certain degree of protection in the event of a collision by being placed on the outside of the drone propeller. In the event of a collision, it is easy to cause imbalance problems after a hard collision, causing the drone to flip over and lose control. Summary of the invention

[0009] According to a further technical solution, the expansion mounting ring is symmetrically provided with sliding ring grooves, a permanent magnetic arc block is slidably mounted on the sliding ring groove, the control connecting rod is mounted on the permanent magnetic arc block, a return spring is mounted on the permanent magnetic arc block, and a control electromagnet is mounted inside the expansion mounting ring.

[0010] According to a further technical solution, an adjusting motor is installed on the inner wall of the protective half ring, and the adjusting motor is dynamically connected to the angle adjusting ring.

[0011] According to a further technical solution, the angle adjustment ring is provided with a matching telescopic portion, and a terminal end of the matching telescopic portion is connected to the protective arc sheet.

[0012] Beneficial effects of the present invention: The high-protective UAV propeller protective cover of the present invention is provided with a sliding elastic protective device on the outer side of the protective semi-ring through the setting of the collision protection function. Therefore, when a collision occurs during flight, the outer elastic protective device first performs a collision buffering effect, and the collision extrusion causes the protective arc sheet to be compressed and retracted, thereby achieving a collision buffering effect through the retraction and pneumatic transmission buffer structure. The pneumatic transmission causes the buffering bag strips in the intervals between the elastic protection strips to be inflated and expanded, so that during the collision process, the expansion of the buffering bag strips can achieve a further collision buffering effect and improve the elasticity of the outer side of the elastic protection strips in the combined state so that it has a certain rebound effect, so as to avoid the problem of hardware damage and imbalance of the UAV caused by hard collision and the existence of subsequent collision injuries. The UAV is suitable for use by UAV beginners and when the UAV is flying in a location with a large number of people such as indoors. The high-protective UAV propeller protective cover of the present invention further improves the protection performance and handling capacity through the setting of the collision protection function and the structural expansion and angle adjustment of the elastic protection device. The transmission structure drives the expansion control device to perform the expansion operation during the collision process, thereby driving the elastic protection strips in the merged state to separate and expand from each other. A telescopic film is installed between the elastic protection strips, so that an umbrella-shaped arc surface protection effect is formed on the outer side of the propeller during the expansion process. The separation of the three elastic protection strips reduces the hardness and increases the elasticity, thereby achieving the function of improving the outer protection range and the collision elastic effect, and a certain shielding effect is achieved through the expansion of the telescopic film and the arc surface dispersion state of the elastic protection strip, thereby avoiding the problem that splashes on the outer side of the collision fly into the propeller range along the edge or the gap between the elastic protection strips, which is dangerous; The high-protection UAV propeller protective cover of the present invention realizes the effect of preventing unbalanced falling by setting the collision protection function and adjusting the angle of the elastic protective device in the unfolded state. The angle adjustment structure drives the elastic protective device to adjust the position relative to the protective semi-ring, thereby driving the umbrella-shaped arc surface structure composed of the elastic protective strips in the separated state to adjust the angle after the collision, thereby performing the imbalance recovery adjustment function. When the propeller blade is damaged, the elastic protective device in the unfolded state is driven to deflect 90 degrees through the angle control structure, so that the umbrella-shaped arc surface structure in the unfolded state is placed on the upper side of the overall structure, thereby achieving the airflow balance effect of vertical deceleration and avoiding unilateral power loss through the umbrella-shaped arc surface structure, thereby avoiding the problem of unbalance caused by unilateral power loss of the UAV due to collision propeller damage, and when multiple sets of protective covers are placed in the unfolded state at the same time and placed in the upper position through angle adjustment, a vertical balance slow landing effect can be achieved, which can be used for safe landing when there is a problem with the collision body and it is not suitable for continued flight or there is insufficient power.

[0016] Combine the following Figure 1-5 The present invention is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front, and back directions mentioned below are the same as Figure 1 The up-down, left-right, front-back directions of the projection relationship itself are consistent.

[0017] A highly protective UAV propeller protective cover described in conjunction with Figures 1-5 includes a mounting block 11, the mounting block 11 is mounted with an extension chassis 12, the extension chassis 12 is mounted with a protective half ring 13, the protective half ring 13 is symmetrically rotated and mounted with an angle adjustment ring 41 on both sides, the angle adjustment ring 41 is slidably mounted with an elastic protective device 15, the elastic protective device 15 includes a protective arc sheet 21, and the two ends of the protective arc sheet 21 are provided with an adjustment mounting portion 23, the adjustment mounting portion 23 is mounted with a deployment control device 25, the deployment control device 25 includes a deployment mounting ring 35, and the deployment control device 25 includes a deployment mounting ring 35. The open mounting ring 35 is installed with three groups of control connecting rods 38, and the outer two groups of control connecting rods 38 can slide along the unfolded mounting ring 35. The control connecting rods 38 are installed with an elastic protective part 30, and the elastic protective part 30 includes three groups of elastic protective strips 31. The two ends of the elastic protective strips 31 are connected to the corresponding control connecting rods 38. Two adjacent elastic protective strips 31 are connected with a telescopic film 33, and the telescopic film 33 is installed with an inflatable cushioning airbag strip 34. The elastic protective strip 31 is provided with a functional groove 32, and the cushioning airbag strip 34 is placed in the functional groove 32.

[0018] During operation, the installation block 11 is connected and fixed to the propeller base, so that the propeller can rotate within the range of the protective semi-ring 13. When a collision occurs during flight, the protective arc sheet 21 is compressed and retracted due to collision extrusion, thereby achieving a collision buffering effect through retraction and pneumatic transmission buffer structure. The pneumatic transmission inflates the buffer airbag strip 34, so that during the collision, the expansion of the buffer airbag strip 34 can achieve further collision buffering effect and have a certain rebound effect to avoid the problem of hardware damage and imbalance of the drone caused by hard collision. At the same time, during the collision, the transmission structure drives the outer control connecting rod 38 to slide outward, thereby driving the elastic protective strip 31 to slide outward and pull the telescopic film 33, thereby forming an umbrella-shaped arc surface protection effect on the outer side of the propeller. The separation of the three elastic protective strips 31 reduces the hardness and increases the elasticity, thereby achieving the function of improving the outer protection range and the collision elasticity effect, and plays a certain role. At the same time, the angle adjustment structure allows the protective arc piece 21 to be adjusted relative to the protective semi-ring 13, thereby driving the umbrella-shaped arc surface structure composed of the separated elastic protective strip 31 to adjust the angle, thereby achieving the imbalance recovery effect. When the propeller blade is damaged, the angle control structure drives the protective arc piece 21 to deflect 90 degrees, so that the umbrella-shaped arc surface structure composed of the separated elastic protective strip 31 is placed on the upper side of the protective semi-ring 13, thereby achieving the vertical direction deceleration and avoiding the airflow balance effect of unilateral power loss through the umbrella-shaped arc surface structure, thereby avoiding the problem of imbalance caused by unilateral power loss of the drone due to propeller damage in the event of a collision. At the same time, when multiple sets of protective covers are placed on the upper side of the protective semi-ring 13 at the same time, a vertical balance and slow landing effect can be achieved, which can be used for safe landing when there is a problem with the collision body and it is not suitable for continued flight or there is insufficient power.
