Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with a quick-release protective cover for the propeller. Background Technology

[0002] The aircraft industry is currently in its early stages. As drone technology matures, drones are being used more and more widely in various industries. Drones have been widely used in many fields such as communication, rescue, forest fire prevention, and security. Drones are mainly composed of a frame and multiple propeller blades. The propeller blades are usually exposed to the outside air. During the flight of a drone, the high-speed rotating propeller blades exposed to the outside air are prone to damaging objects, and the high-speed rotating propeller blades exposed to the outside air pose a risk of scratching users.

[0003] Chinese patent CN208264555U discloses a drone with a propeller guard, comprising: a drone frame, propeller blades, a motor, and a guard. The motor is mounted on the drone frame. Each propeller blade has a central mounting hole, and the motor's output shaft is inserted into the mounting hole. The guard covers the propeller blades, with a gap between the guard and the blades. The guard is mounted on the motor's housing. By attaching the guard to the outside of the propeller blades, the blades are prevented from being directly exposed to the outside environment, thus preventing damage to objects during flight, preventing blades from tangling in the event of a collision between two drones, and preventing injuries to the user from rotating propeller blades.

[0004] However, the aforementioned drones with propeller shields cannot be easily disassembled and replaced after the shields are damaged by impact. The non-convenient disassembly and assembly of the protective shells requires staff to use professional tools or complicated procedures, such as disassembling the entire frame and reworking the welding, which prolongs the repair time and affects the normal use efficiency of the drone. Utility Model Content

[0005] The purpose of this invention is to provide a drone with a quick-release protective cover for the propeller, so as to solve the problem mentioned in the background art that the protective cover cannot be easily disassembled and replaced.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drone with a quick-release protective cover for a propeller includes: a drone body, on both sides of a connecting arm of the drone body, a retractable groove is provided, an insertion mechanism is slidably installed in the retractable groove, an insertion port is provided on the upper surface of the connecting arm, the insertion port can be used to insert a plug, thereby applying lateral limitation to the plug, and a protective shell is fixedly installed on the upper surface of the plug, so that the plug inserted into the insertion port can drive the protective shell to be fitted around the propeller.

[0008] Preferably, the insertion port is connected to the shrinkage groove, and a limiting groove is provided on both sides of the insertion block, so that the limiting groove can be flush with and connected to the shrinkage groove provided on both sides of the connecting arm, and the limiting groove can be inserted into the insertion port along with the insertion block and be flush with the insertion end of the insertion mechanism.

[0009] Preferably, the insertion mechanism includes a U-shaped frame, which is slidably installed in the shrinkage groove. Limiting blocks are fixedly installed at both ends of the inner side of the U-shaped frame. The limiting blocks can slide into the limiting groove along with the sliding of the U-shaped frame, thereby applying a vertical limit to the insertion block.

[0010] Preferably, rubber push plates are fixedly installed at both ends of the outer surface of the U-shaped frame.

[0011] Preferably, a guide post is fixedly installed at one end of the shrinkage groove, and the guide post slides through the U-shaped frame and is fitted with a spring on its outer surface.

[0012] Preferably, the two ends of the spring are fixedly connected to one end inside the shrink groove and one end of the U-shaped frame, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the connecting arm, shrink groove, insertion port, protective shell, insertion block, limiting groove, and insertion mechanism, when installing the protective shell, the operator can slide the insertion mechanism backward through the shrink groove and be subjected to a forward spring force. Then, the operator can insert the insertion block of the protective shell into the insertion port to apply a lateral limiting force to the insertion block. As the insertion block is fully inserted, it will drive the limiting grooves on both sides to be flush with the insertion end of the insertion mechanism. The fully inserted insertion block will also drive the protective shell to be fitted around the propeller. Then, the operator can release the pull on the insertion mechanism, allowing it to automatically reset and insert into the limiting grooves on both sides of the insertion block by means of internal elastic thrust. This mechanism applies a vertical limiting force to the insert block, thus securing the protective shell in place. Disassembly is simple: just pull the insert mechanism back to allow it to slide out of the limiting slots on both sides of the insert block. Then, the worker can pull up the protective shell to lift the insert block out of the limiting slots. Installation requires only three core actions: "pull back the insert mechanism → insert the insert block → release and reset," eliminating the need for complex alignment or multiple tools. Workers can complete the process quickly with one or both hands, significantly reducing installation time. Disassembly simply requires pulling the insert mechanism back to disengage it from the limiting slots, allowing the worker to directly pull up the protective shell to remove the insert block without reverse rotation, screw removal, or damage to other structures, significantly improving the efficiency of the protective shell's assembly and disassembly.

[0015] 2. Through the design of guide posts, springs, U-shaped frames, and limiting blocks, when installing the protective shell, the worker pinches the rubber push plate and pulls the U-shaped frame backward, causing it to slide along the guide post towards the rear of the shrinkage groove. During this process, the spring is compressed and stores elastic potential energy, while the limiting block moves backward with the U-shaped frame and exits its initial position. Then, the worker can insert the protective shell's insert block into the insertion port. The inserted insert block can drive the limiting grooves on both sides to align with the shrinkage groove and be flush with the limiting block on the inner side of the U-shaped frame. Then, the worker can release the rubber push plate to allow the compressed spring to release its elastic potential energy and push the U-shaped frame to slide forward along the guide post. This allows the U-shaped frame to drive the inner limiting block forward and insert it into the limiting groove, forming a vertical limiting on the insert block. Combined with the lateral limiting formed by the insertion of the insert block into the insertion port, this completes the assembly of the protective shell.

[0016] During disassembly, the operator pinches the rubber push plate again, pulls the U-shaped frame backward, and compresses the spring to disengage the limiting block from the limiting groove, releasing the vertical limitation. At this point, the protective shell is pulled upward to pull the insert block out of the insertion port, completely releasing the lateral limitation and completing the disassembly process. Throughout the process, the guide column ensures that the U-shaped frame slides only along the axial direction to avoid lateral displacement and jamming. The rubber push plate provides a non-slip feel for easy manual application of force and cushioning. The elastic potential energy of the spring drives automatic locking and unlocking. No external energy is required. The purely mechanical drive meets the lightweight requirements of the drone body. In terms of operation, the purely mechanical structure combined with simple push and pull actions lowers the threshold of use. No professional tools or complicated training are required, significantly improving the efficiency of disassembly and assembly of the protective shell. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2As shown, a drone with a quick-release protective cover for a propeller includes: a drone body 1, a retraction groove 102 on both sides of a connecting arm 101 of the drone body 1, an insertion mechanism 2 slidably installed in the retraction groove 102, an insertion port 103 on the upper surface of the connecting arm 101, an insertion block 105 can be inserted into the insertion port 103 to achieve lateral limiting of the insertion block 105, and a protective shell 104 is fixedly installed on the upper surface of the insertion block 105 so that the insertion block 105 inserted into the insertion port 103 can drive the protective shell 104 to be fitted around the propeller. The insertion port 103 is connected to the shrinkage groove 102. Limiting grooves 106 are provided on both sides of the insertion block 105, so that the limiting grooves 106 can be flush with and connected to the shrinkage grooves 102 provided on both sides of the connecting arm 101, and the limiting grooves 106 can be inserted into the insertion port 103 together with the insertion block 105 and be flush with the insertion end of the insertion mechanism 2.

[0023] Through the design of the connecting arm 101, shrink groove 102, insertion port 103, protective shell 104, insertion block 105, limiting groove 106, and insertion mechanism 2, when installing the protective shell 104, the operator can slide the insertion mechanism 2 backward through the shrink groove 102 and be subjected to a forward spring force. Then, the operator can insert the insertion block 105 of the protective shell 104 into the insertion port 103 to apply a lateral limiting force to the insertion block 105. As the insertion block 105 is fully inserted, it will cause the limiting grooves 106 on both sides to align with the insertion end of the insertion mechanism 2. The fully inserted insertion block 105 will also cause the protective shell 104 to be fitted around the propeller. The operator can then release the pull on the insertion mechanism 2, allowing it to automatically reset and insert into the grooves 106 on both sides of the insertion block 105 using its internal elastic thrust. The limiting groove 106 is used to apply a vertical limiting force to the insert 105, thereby securing the protective shell 104. During disassembly, simply pull the insert mechanism 2 back to allow it to slide out of the limiting groove 106 on both sides of the insert 105. Then, the operator can pull up the protective shell 104 to lift the insert 105 out of the limiting groove 106. During installation, only three core actions are required: "pull back the insert mechanism 2 → insert the insert 105 → release and reset". No complicated alignment or multiple tools are needed. The operator can complete the installation quickly with one or two hands, greatly shortening the installation time. During disassembly, simply pull the insert mechanism 2 back to disengage it from the limiting groove 106, and then pull up the protective shell 104 to remove the insert 105. There is no need for reverse rotation, screw removal, or damage to other structures, which significantly improves the disassembly and assembly efficiency of the protective shell 104.

[0024] like Figure 3As shown, the insertion mechanism 2 includes a U-shaped frame 203, which is slidably installed in the shrinkage groove 102. Limiting blocks 204 are fixedly installed at both ends of the inner side of the U-shaped frame 203. The limiting blocks 204 can slide into the limiting groove 106 as the U-shaped frame 203 slides, thereby applying a vertical limit to the insertion block 105. Rubber push plates 205 are fixedly installed at both ends of the outer surface of the U-shaped frame 203. A guide post 201 is fixedly installed at one end inside the shrinkage groove 102. The guide post 201 slides through the U-shaped frame 203 and has a spring 202 fitted on its outer surface. The two ends of the spring 202 are fixedly connected to one end inside the shrinkage groove 102 and one end of the U-shaped frame 203, respectively.

[0025] Through the design of the guide post 201, spring 202, U-shaped frame 203, and limiting block 204, when installing the protective shell 104, the worker holds the rubber push plate 205 and pulls the U-shaped frame 203 backward, causing it to slide along the guide post 201 towards the rear of the contraction groove 102. During this process, the spring 202 is compressed and stores elastic potential energy, while the limiting block 204 moves backward with the U-shaped frame 203 and exits its initial position. Then, the worker can insert the insert block 105 of the protective shell 104 into the insertion port 103, and the inserted insert block 105 can drive the two sides... The limiting groove 106 is aligned with the shrink groove 102 and flush with the limiting block 204 on the inner side of the U-shaped frame 203. Then, the staff can release the rubber push plate 205 to release the elastic potential energy of the compressed spring 202 and push the U-shaped frame 203 to slide forward along the guide post 201. This allows the U-shaped frame 203 to move the inner limiting block 204 forward and insert it into the limiting groove 106, forming a vertical limiting on the insert 105. This, together with the insertion of the insert 105 into the insertion port 103, forms a lateral limiting, thus realizing the assembly of the protective shell 104.

[0026] During disassembly, the operator pinches the rubber push plate 205 again, pulls the U-shaped frame 203 backward, and compresses the spring 202 to make the limiting block 204 exit from the limiting groove 106, releasing the vertical limiting. At this time, the protective shell 104 is pulled upward to drive the insertion block 105 out of the insertion port 103, completely releasing the lateral limiting and completing the disassembly process of the protective shell 104. Throughout the process, the guide column 201 ensures that the U-shaped frame 203 slides only along the axial direction to avoid lateral displacement and jamming. The rubber push plate 205 provides a non-slip feel to facilitate manual force application and buffering force. The elastic potential energy of the spring 202 drives automatic locking and unlocking. No external energy is required. The pure mechanical drive meets the lightweight requirements of the UAV body 1. In terms of operation, the pure mechanical structure combined with simple push and pull actions lowers the threshold of use. No professional tools and complicated training are required, which significantly improves the disassembly and assembly efficiency of the protective shell 104.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: When installing the protective shell 104, the worker holds the rubber push plate 205 and pulls the U-shaped frame 203 backward, causing it to slide along the guide post 201 towards the rear of the contraction groove 102. During this process, the spring 202 is compressed and stores elastic potential energy, and the limiting block 204 can move backward with the U-shaped frame 203 and exit its initial position. Then, the worker can insert the insert block 105 of the protective shell 104 into the insertion port 103. The inserted insert block 105 can drive the limiting grooves 106 on both sides to align with the contraction groove 102 and be flush with the limiting block 204 on the inner side of the U-shaped frame 203. The fully inserted insert block 105 will also drive the protective shell 104 to be fitted around the propeller. Then, the worker can release the grip on the rubber push plate 205, allowing the compressed spring to release its potential energy. Spring 202 releases elastic potential energy to push U-shaped frame 203 to slide forward along guide post 201, thereby allowing U-shaped frame 203 to move the inner limiting block 204 forward and insert it into the limiting groove 106, forming a vertical limiting on the insert 105, and cooperating with the lateral limiting formed by the insertion of the insert 105 into the insertion port 103, thus realizing the assembly of the protective shell 104. When disassembling, it is necessary to squeeze the rubber push plate 205 again to pull the U-shaped frame 203 backward and compress the spring 202 to make the limiting block 204 exit from the limiting groove 106, releasing the vertical limiting. At this time, the protective shell 104 is pulled upward to drive the insert 105 out of the insertion port 103, completely releasing the lateral limiting, and completing the disassembly process of the protective shell 104. In the whole process, only simple pushing and pulling actions are needed to complete the assembly and disassembly of the protective shell 104.

[0028] In summary, through a purely mechanical structural design, the disassembly and assembly process of the protective shell 104 is simplified to standardized actions such as pushing and pulling, requiring no professional tools or complex training, which significantly improves the disassembly and assembly efficiency of the protective shell 104.
