Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) technology, specifically a UAV propeller protective cover. Background Technology

[0002] A drone propeller guard is an external protective device specifically designed for drones. Its core function is to reduce the risk of propeller damage during flight due to collisions, entanglement, or accidental contact through physical isolation and structural protection, thereby improving flight safety. It is typically installed around the drone propeller and is usually made of lightweight, high-strength materials (such as plastics, carbon fiber, and aluminum alloys), forming a barrier to: 1. Prevent the propeller from directly colliding with obstacles (such as tree branches, walls, and power lines); 2. Avoid propeller cuts to people or animals (especially during low-altitude flights or in densely populated areas); 3. Reduce the risk of foreign objects getting tangled (such as kite strings or ropes) and prevent loss of control due to blade jamming.

[0003] The existing drone propeller guards are installed separately on the outside of the four drone propellers. While this sequential installation allows for targeted disassembly and replacement of damaged parts, it also increases the installation time, significantly increases labor intensity, and reduces installation efficiency. Therefore, an improvement is needed. Summary of the Invention

The bottom of the synchronous pressing plate is elastically connected to the inner wall of the protective cover splicing frame through a first connecting spring.

[0007] Preferably, the inner wall of the first connecting spring is slidably connected to the surface of the first limiting sliding rod.

[0008] Preferably, the splicing and disassembly mechanism includes a movable splicing plate, a drive block, a second locking and fixing assembly, an auxiliary disassembly assembly, and a third connecting spring; The movable splicing plate is slidably installed in the inner cavity of the drone protective cover. The driving block is fixedly installed in the middle of the top of the movable splicing plate. The second locking and fixing component is installed on the outer side inside the movable splicing plate. The auxiliary disassembly component is movably sleeved in the middle of the movable splicing plate, and the bottom end of the auxiliary disassembly component extends to the bottom of the drone protective cover. The bottom of the movable splicing plate is elastically connected to the inner wall of the drone protective cover through a third connecting spring.

[0009] Preferably, the protruding portions on both sides of the top of the drive block are slidably connected to the inner wall of the inclined groove formed on the triangular transmission block.

[0010] Preferably, the second locking and fixing assembly includes an L-shaped transmission block, a second fixing and clamping block, and a second connecting spring; The L-shaped transmission block is slidably installed on the outer side inside the movable splicing plate, and the second fixing clamping block is fixedly installed on the outer end of the L-shaped transmission block. The inner end of the second fixing clamping block is elastically connected to the inner wall of the movable splicing plate through the second connecting spring.

[0011] Preferably, the auxiliary disassembly assembly includes a transmission rotary disk, a transmission connecting rod, and a drive rotating rod; The transmission rotary disk is movably sleeved in the middle of the movable splicing disk and located below the inner end of the second fixed clamping block. The transmission connecting rod is fixedly sleeved in the middle of the transmission rotary disk. The bottom end of the transmission connecting rod is slidably connected to the top of the drive rotating rod movably sleeved at the bottom of the drone protective cover.

[0012] Preferably, the protruding portion at the top of the transmission rotary disk is slidably connected to the inner wall of the inner groove of the L-shaped transmission block.

[0013] Preferably, a shielding component is installed at the bottom of the drone protective cover, the shielding component including a shielding cover, a first magnet and a second magnet; The shielding cover is hinged to the bottom of the drone protective cover. The first magnet is located inside one side of the shielding cover, and the second magnet is installed inside the drone protective cover and located directly above the first magnet.

[0014] Preferably, the first magnet and the second magnet are exactly the same size and their magnetic poles are opposite.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of a push-button component, a first locking and fixing component, and a drive block, allows for the installation of a drone protective cover and its splicing frame at the bottom of a drone propeller. First, the first locking and fixing component on the top of the drone protective cover is inserted into the bottom outer end of the drone propeller. Simultaneously, the push-button component on one side is pushed downwards, causing the drive block and the movable splicing plate to move downwards. This drives the top portion of the first locking and fixing component towards each other. Finally, the push-button component is released, releasing the top portion of the first locking and fixing component and allowing it to move in opposite directions. This allows the drone protective cover and its splicing frame to be quickly installed on the bottom outer side of the drone propeller, significantly reducing labor intensity and improving installation efficiency. This invention, through the cooperation of structures such as a second locking and fixing component and an auxiliary disassembly component, allows for the disassembly and repair of a single drone protective cover when necessary. First, the bottom of the auxiliary disassembly component can be rotated, causing the entire auxiliary disassembly component to rotate and move the second locking and fixing component. This allows the protruding part of the second locking and fixing component to disengage from the push-button component, thereby releasing the single protective cover splicing frame from its splicing and fixing effect. Ultimately, the single drone protective cover can be disassembled for repair, further improving the efficiency of subsequent repair and replacement. This invention utilizes a combination of a first magnet and a second magnet. Since the magnetic poles of the first magnet and the second magnet are opposite, they attract each other. When the two magnets are in contact, the protective cover can be fixed and blocked at the bottom of the auxiliary disassembly component. This achieves the effect of shielding and protecting the auxiliary disassembly component when it is not in use, thereby preventing accidental disassembly of a single drone protective cover. At the same time, it strengthens the fixing effect of splicing a single drone protective cover at the four corners of the protective cover splicing frame.

[0016] This invention, by setting up a triangular transmission block and a drive block, can drive the movable splicing plate and the drive block to move up and down synchronously when the drive pressing component moves up and down. Since the protruding parts on both sides of the top of the drive block slide along the inclined groove inside the triangular transmission block, the two first fixed clamping blocks will move horizontally towards or away from each other, thus achieving the effect of quick installation and locking of the protective cover component at the bottom of the UAV propeller.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 9As shown, the present invention provides a drone propeller protective cover, including a drone body 100, and further including: a drone propeller 200 disposed on the outside of the drone body 100; a protective cover assembly 300 mounted on the bottom of the outside of the drone propeller 200; a first locking and fixing assembly 400 mounted on the top of the four corners of the protective cover assembly 300; and a splicing and disassembly mechanism 500 slidably mounted inside the protective cover assembly 300 and located directly below the first locking and fixing assembly 400; wherein, the first locking and fixing assembly 400... The 00 includes a second limiting sliding rod 410 fixedly installed above the splicing and disassembly mechanism 500. A first fixing clamping block 420 is slidably installed on both sides of the surface of the second limiting sliding rod 410. A triangular transmission block 430 is provided at the bottom of the inner side of the first fixing clamping block 420. The protective cover assembly 300 includes a drone protective cover 310 installed on the bottom of the outer side of the drone propeller 200. A protective cover splicing frame 320 is spliced ​​between the drone protective covers 310. A pressing component 330 is provided inside the protective cover splicing frame 320.

[0021] When the push-button component 330 is pushed downwards, the splicing and disassembly mechanism 500 moves downwards synchronously. At this time, the top of the splicing and disassembly mechanism 500 drives the triangular transmission block 430 and the first fixing clamping block 420 to move towards each other. Moreover, due to the design of the second limiting sliding rod 410, the horizontal movement of the two triangular transmission blocks 430 and the first fixing clamping block 420 is restricted. Then, the first fixing clamping block 420 is inserted into the inner cavity at the bottom of the outer side of the drone propeller 200. Finally, the push-button component 330 is released, so that the triangular transmission block 430 and the first fixing clamping block 420 are released and reset. Then, the outer end of the first fixing clamping block 420 is inserted into the inner cavity at the bottom of the drone propeller 200 from opposite directions, so that the drone protective cover 310 and the protective cover splicing frame 320 are synchronously fixed and installed at the bottom of the drone propeller 200.

[0022] like Figure 3 and Figure 4 As shown, the pressing component 330 includes a first limiting sliding rod 331, a synchronous pressing plate 332, and a first connecting spring 333; The first limiting sliding rod 331 is fixedly installed inside the protective cover splicing frame 320, and the synchronous pressing plate 332 is slidably installed on the surface of the first limiting sliding rod 331. The bottom of the synchronous pressing plate 332 is elastically connected to the inner wall of the protective cover splicing frame 320 through the first connecting spring 333.

[0023] Using the above solution: when the middle of the synchronous pressing plate 332 at a certain position is pushed, the synchronous pressing plate 332 and the splicing and disassembly mechanism 500 will move downward synchronously as a whole. This will cause the top part of the splicing and disassembly mechanism 500 to drive the triangular transmission block 430 and the first fixing clamping block 420 to move towards each other, so as to release the fixing effect of the drone protective cover 310 and the protective cover splicing frame 320 on the bottom of the drone propeller 200, and achieve the effect of quickly disassembling the drone protective cover 310 and the protective cover splicing frame 320 as a whole.

[0024] like Figure 3 and Figure 4 As shown, the inner wall of the first connecting spring 333 is slidably connected to the surface of the first limiting sliding rod 331.

[0025] The above solution is adopted because the design of the first limiting sliding rod 331 can limit the overall up and down movement of the synchronous pressing plate 332, while also limiting the passive extension and retraction of the first connecting spring 333.

[0026] like Figure 4 , Figure 5 and Figure 9 As shown, the splicing and disassembly mechanism 500 includes a movable splicing plate 510, a drive block 520, a second locking and fixing assembly 530, an auxiliary disassembly assembly 540, and a third connecting spring 550. The movable splicing plate 510 is slidably installed in the inner cavity of the drone protective cover 310. The drive block 520 is fixedly installed in the middle of the top of the movable splicing plate 510. The second locking and fixing component 530 is installed on the outer side inside the movable splicing plate 510. The auxiliary disassembly component 540 is movably sleeved in the middle of the movable splicing plate 510, and the bottom end of the auxiliary disassembly component 540 extends to the bottom of the drone protective cover 310. The bottom of the movable splicing plate 510 is elastically connected to the inner wall of the drone protective cover 310 through the third connecting spring 550.

[0027] The above solution is adopted: when the movable splicing plate 510 moves downward, it will compress the third connecting spring 550. When the movable splicing plate 510 loses the downward pressing force, the elastic force of the third connecting spring 550 will be released, which can help push the movable splicing plate 510 to move upward and reset.

[0028] like Figure 5 As shown, the protruding parts on both sides of the top of the drive block 520 are slidably connected to the inner wall of the inclined groove opened on the triangular transmission block 430.

[0029] Using the above solution: when the movable splicing plate 510 and the drive block 520 move up and down as a whole, the protruding parts on both sides of the top of the drive block 520 will slide and connect inside the inclined groove of the triangular transmission block 430, thereby enabling the drive triangular transmission block 430 and the first fixed clamping block 420 to move towards or away from each other.

[0030] like Figure 9 As shown, the second locking and fixing assembly 530 includes an L-shaped transmission block 531, a second fixing and clamping block 532, and a second connecting spring 533; The L-shaped transmission block 531 is slidably installed on the outer side inside the movable splicing plate 510. The second fixing clamping block 532 is fixedly installed on the outer end of the L-shaped transmission block 531. The inner end of the second fixing clamping block 532 is elastically connected to the inner wall of the movable splicing plate 510 through the second connecting spring 533.

[0031] Using the above solution: Due to the elastic force of the second connecting spring 533, the L-shaped transmission block 531 and the second fixing clamping block 532 can be pushed to move outward, so that the second fixing clamping block 532 can be locked inside the protective cover splicing frame 320, thereby achieving the effect of fixing the UAV protective cover 310 to the four corners of the protective cover splicing frame 320.

[0032] like Figure 4 and Figure 5 As shown, the auxiliary disassembly assembly 540 includes a transmission rotary disk 541, a transmission connecting rod 542, and a drive rotary rod 543; The transmission rotary disk 541 is movably sleeved in the middle of the movable splicing disk 510 and located below the inner end of the second fixed clamping block 532. The transmission connecting rod 542 is fixedly sleeved in the middle of the transmission rotary disk 541. The bottom end of the transmission connecting rod 542 is slidably connected to the top of the drive rotating rod 543, which is movably sleeved at the bottom of the UAV protective cover 310.

[0033] The above solution allows the movable splicing plate 510 and the transmission connecting rod 542 to slide smoothly downwards, while still maintaining the effect of synchronous rotation of the transmission connecting rod 542 and the drive rotating rod 543, due to the design of the bottom end of the transmission connecting rod 542 slidingly connected to the top of the drive rotating rod 543.

[0034] like Figure 4 As shown, the protruding part at the top of the transmission rotary disk 541 is slidably connected to the inner wall of the inner groove of the L-shaped transmission block 531.

[0035] Using the above solution: when the rotating drive rod 543 drives the transmission connecting rod 542 and the transmission rotating disk 541 to rotate synchronously, the protruding part at the top of the transmission rotating disk 541 will move on the inner wall of the inner groove of the L-shaped transmission block 531, thereby driving the L-shaped transmission block 531 and the second fixed clamping block 532 to move inward until the second fixed clamping block 532 is disengaged from the interior of the protective cover splicing frame 320, thereby achieving the splicing and fixing effect between the single UAV protective cover 310 and the protective cover splicing frame 320.

[0036] like Figure 6 As shown, a shielding component 600 is installed at the bottom of the drone protective cover 310. The shielding component 600 includes a shielding cover 610, a first magnet 620, and a second magnet 630. The shield 610 is hinged to the bottom of the drone protective cover 310. The first magnet 620 is located inside one side of the shield 610, and the second magnet 630 is installed inside the drone protective cover 310 and located directly above the first magnet 620.

[0037] The above solution is adopted: by designing the protective cover 610, the bottom of the auxiliary disassembly component 540 can be protected when it is not in use.

[0038] like Figure 6 As shown, the first magnet 620 and the second magnet 630 are exactly the same size and their magnetic poles are opposite.

[0039] The above solution is adopted because the first magnet 620 and the second magnet 630 have opposite magnetic poles, which can create a mutual attraction force between them. This can stabilize the shielding cover 610 on the top of the drone protective cover 310 and achieve a stable shielding effect on the auxiliary disassembly component 540.

[0040] Working principle and usage process of this invention: First, when the operator needs to install the drone protective cover 310 and the protective cover splicing frame 320 as a whole on the outer bottom of the drone propeller 200, the synchronous pressing plate 332 can be pushed vertically downward along the surface of the first limiting sliding rod 331, and the first connecting spring 333 can be compressed. At this time, the downward movement of the synchronous pressing plate 332 can drive the multiple movable splicing plates 510 and the drive block 520 to move downward synchronously as a whole, so that the protruding parts on both sides of the top of the drive block 520 slide along the inner wall of the inclined groove of the triangular transmission block 430, thereby driving the two triangular transmission blocks 430 and the first fixing clamping block 420 to slide horizontally towards each other along the surface of the second limiting sliding rod 410. Then, the first fixing clamping block 420 can be inserted into the inner cavity at the bottom of the outer side of the drone propeller 200. Then, the synchronous pressing plate 332 is released, causing the first connecting spring 333 to release its elasticity and push it, the movable splicing plate 510, and the driving block 520 to move upward as a whole. This causes the protruding parts on both sides of the top of the driving block 520 to slide along the inclined groove of the triangular transmission block 430, thereby driving the triangular transmission block 430 and the first fixing clamping block 420 to be driven to reset in opposite directions. Finally, the outer end of the first fixing clamping block 420 is locked in the inner cavity at the bottom of the drone propeller 200, so that the drone protective cover 310 and the protective cover splicing frame 320 are fixedly installed at the bottom of the drone propeller 200.

[0041] When a drone protective cover 310 is damaged and needs to be disassembled and replaced for repair, the shielding cover 610 can be opened by first pulling it open. Then, rotating the drive rod 543 will drive the transmission connecting rod 542 and the transmission rotating disk 541 to rotate synchronously. This will cause the protruding part at the top of the transmission rotating disk 541 to slide along the inner wall of the inner groove of the L-shaped transmission block 531, so that the L-shaped transmission block 531 and the second fixing clamping block 532 will move synchronously inward until the second fixing clamping block 532 is completely disengaged from the inside of the synchronous pressing plate 332, thus releasing the overall fixing and splicing effect of the single drone protective cover 310 and the protective cover splicing frame 320. Subsequently, the drive rotating rod 543 can be pulled to drive the transmission connecting rod 542, transmission rotating disk 541, movable splicing disk 510 and drive block 520 to move downward as a whole. Finally, the protruding parts on both sides of the top of the drive block 520 slide on the inner wall of the inclined groove of the triangular transmission block 430, thereby causing the two triangular transmission blocks 430 and the first fixed clamping block 420 to move in opposite directions. This causes the outer end of the first fixed clamping block 420 to disengage from the inner cavity of the bottom of the drone propeller 200, releasing the fixing effect of the single drone protective cover 310 on the bottom of the drone propeller 200. Then, the single drone protective cover 310 can be removed for replacement and maintenance.
