Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a collision protection device for UAV propellers. Background Technology

[0002] With the widespread application of drone technology in aerial photography, logistics, agricultural plant protection, and other fields, the propeller, as the core power component of drones, directly affects the operational efficiency and flight safety of drones due to its operational safety and integrity. Currently, most drone propeller anti-collision protection devices on the market have relatively simple structures, mostly adopting a fixed integrated protective frame design, which can only achieve basic anti-collision functions.

[0003] Such fixed structures have obvious limitations: on the one hand, they cannot flexibly adjust the protection strength and range according to different usage scenarios. For example, when operating in an open environment, a fixed protective frame will increase the overall weight of the drone, resulting in a decrease in endurance; on the other hand, when operating in a complex obstacle environment, the existing protective structure is difficult to provide comprehensive protection and is prone to damage to the propeller due to collisions, making it difficult to meet diverse usage needs. Therefore, this application proposes a collision protection device for drone propellers to solve the above problems. Utility Model Content

The positioning sleeve 2 is fitted and fixed on the base of the propeller body 1 by bolts, thereby realizing the installation of multiple protective frames 3 and the outer protective ring frame 4 on the bottom side and periphery of the propeller blades of the propeller body 1. Figure 2 As shown, at this time, multiple protective frames 3 and outer protective ring frames 4 can protect the bottom side and periphery of the propeller body 1 blade. An inner protective ring frame 5 is connected to the outer protective ring frame 4. The height of the outer protective ring frame 4 and the inner protective ring frame 5 is higher than the propeller body 1 blade. Multiple protective frames 6 are installed on the inner protective ring frame 5, and the protective frames 6 are located on the bottom side of the propeller body 1 blade. The other end of the protective frames 6 is attached to the positioning sleeve 2. The side of the protective frames 6 that connects to the positioning sleeve 2 can use a magnetic attraction structure to ensure that the protective frames 6 are magnetically attached to the positioning sleeve 2. If the upper and lower periphery of the propeller body 1 blade needs protection, the inner protective ring frame 5 can be attached to the upper side of the outer protective ring frame 4, so that the outer protective ring frame 4 and the inner protective ring frame 5 form a semi-enclosed shape. Figure 4As shown, the combination of the upper and lower protective frames 6 and 3, as well as the outer protective ring frame 4 and inner protective ring frame 5, can protect the upper and lower sides of the propeller body 1 blade. The outer protective ring frame 4 and inner protective ring frame 5 form a ring after docking, and their two sides are connected by a docking sleeve 7. The docking sleeve 7 has slots on both sides for inserting the outer protective ring frame 4 and inner protective ring frame 5 into each other, and is secured with bolts. The inner protective ring frame 5 fits snugly against the outer protective ring frame 4, and the inner protective ring frame 5 provides internal protection. After the inner protective ring frame 5 is attached to the outer protective ring frame 4, both ends are connected by the second docking sleeve 8. The second docking sleeve 8 has a large slot on one side, which is used to insert the outer protective ring frame 4 and the inner protective ring frame 5 into the large slot of the second docking sleeve 8 after they are attached together and locked with bolts. After the inner protective ring frame 5 is attached to the outer protective ring frame 4, the first protective frame 3 and the second protective frame 6 are located on the lower and upper sides of the propeller blade of the propeller body 1, respectively. If there are many obstacles in the working environment, the inner protective ring frame 5 is attached to the outer protective ring frame 4, so that the outer protective ring frame 4 and the inner protective ring frame 5 form a ring shape. Figure 1 and 3 As shown, at this time, the protective frame 1 (3), outer protective ring frame 4, inner protective ring frame 5, and protective frame 2 (6) can provide overall protection for the underside and periphery of the blade.

[0026] Example 2

[0027] Based on Embodiment 1, an embodiment with a top protective frame 9 is also provided, such as... Figure 5 As shown, the outer protective ring frame 4 and the inner protective ring frame 5 form a circular joint, and a top protective frame 9 is connected to the upper side. The top protective frame 9, the outer protective ring frame 4, and the inner protective ring frame 5 are connected by a connecting sleeve 10. The connecting sleeve 10 has slots on both sides and the top side, which are used to insert the outer protective ring frame 4 and the inner protective ring frame 5 into the slots on both sides of the connecting sleeve 10 when they are joined. The top slot is used for the insertion of the top protective frame 9, and it is fixed by bolts. The top protective frame 9 consists of a ring-shaped outer frame and multiple protective strips. By connecting the top protective frame 9 to the circular outer protective ring frame 4 and the inner protective ring frame 5, the inner protective ring frame 5, the outer protective ring frame 4, and the top protective frame 9 are connected by the connecting sleeve 10. Figure 5 As shown, the propeller body 1 can achieve overall protection of the upper and lower sides of the blades and the periphery through the protective frame 1 3, the protective frame 2 6, the outer protective ring frame 4, the inner protective ring frame 5 and the top protective frame 9.

[0028] The operational steps for this application are as follows:

[0029] Positioning sleeve 2 is fitted and fixed onto the base of propeller body 1 using bolts, thereby installing multiple protective frames 3 and outer protective ring frame 4 on the bottom and periphery of the propeller body 1 blades. Figure 2As shown, at this time, multiple protective frames 3 and outer protective ring frames 4 can protect the bottom side and the periphery of the propeller body 1 blades;

[0030] If the upper and lower outer sides of the propeller blades of the propeller body 1 need protection, the inner protective ring frame 5 can be fitted and mated to the upper side of the outer protective ring frame 4, so that the outer protective ring frame 4 and the inner protective ring frame 5 form a semi-enclosed shape, such as Figure 4 As shown, the combination of the upper and lower protective frames 6, 3, outer protective ring frame 4 and inner protective ring frame 5 can protect the upper and lower sides of the propeller body 1 blade.

[0031] If the working environment has many obstacles, the inner protective ring frame 5 should be fitted and connected to the outer protective ring frame 4, so that the outer protective ring frame 4 and the inner protective ring frame 5 form a ring shape. Figure 1 and 3 As shown, at this time, the protective frame 1 3, the outer protective ring frame 4, the inner protective ring frame 5, and the protective frame 2 6 can provide overall protection for the underside and periphery of the blade;

[0032] Simultaneously, according to requirements, the top protective frame 9 is connected to the annular outer protective ring frame 4 and inner protective ring frame 5. The inner protective ring frame 5, outer protective ring frame 4, and top protective frame 9 are connected via a connecting sleeve 10. Figure 5 As shown, the propeller body 1 can achieve overall protection of the upper and lower sides of the blades and the periphery through the protective frame 1 3, the protective frame 2 6, the outer protective ring frame 4, the inner protective ring frame 5 and the top protective frame 9.
