Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV anti-collision structure. Background Technology

[0002] Unmanned vehicles, also known as drones, are devices operated using radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. These include unmanned aerial vehicles, unmanned vehicles, and robot dogs.

[0003] During flight, drones are easily damaged by impacts from external objects. Therefore, some people usually install anti-collision structures on the power equipment of drones. For example, Chinese utility model patent with announcement number CN212473898U discloses a drone anti-collision device.

[0004] However, in actual use, it has been found that the existing anti-collision structures used on drones are difficult to disassemble, which prolongs the time for maintenance or replacement of parts, especially in scenarios with frequent maintenance (such as agricultural spraying and logistics transportation), and may cause operation delays. Utility Model Content

[0005] The purpose of this invention is to provide a collision avoidance structure for unmanned aerial vehicles (UAVs) that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drone anti-collision structure, comprising a drone body, protective components, anti-collision pads, limiting components, and locking components.

[0007] The drone's main body is equipped with several support rods on its sides, each with a thruster at its end. A protective assembly is located outside the thruster, a collision pad is located outside the protective assembly, a limiting assembly is mounted on the support rod, and a locking assembly is mounted on the protective assembly. The protective assembly is fixed to the limiting assembly via the locking assembly. The protective assembly protects the thruster, the collision pad provides impact cushioning, and the locking assembly facilitates the installation and removal of the protective assembly.

[0008] In a preferred embodiment of this invention, the protective assembly includes a first protective cover, a second protective cover, and a trainer, with hinges fixed to one end of the first and second protective covers. The first and second protective covers, when installed together, protect the propeller and provide anti-collision protection. The hinges connect the first and second protective covers, allowing them to rotate relative to each other for easy opening and closing.

[0009] As a preferred embodiment of this invention, both the first and second protective covers are semi-circular in shape, and both are made of carbon fiber sheet. When the first and second protective covers are combined and installed, they form a complete circular ring, improving the protective effect. The first and second protective covers made of carbon fiber sheet offer good impact resistance and are lightweight.

[0010] As a preferred embodiment of this invention, the anti-collision pad has several pressure relief holes that extend through it, and the anti-collision pad is made of rubber. The rubber anti-collision pad, combined with the pressure relief holes, provides a cushioning effect and improves its anti-collision capability.

[0011] In a preferred embodiment of this invention, the limiting component includes a locking bar, positioning blocks, locking screw holes, and limiting blocks. The locking bar is fixed to the support rod. Several positioning blocks are provided and fixed to the outer side of the locking bar. The locking screw holes are formed on the side wall of the locking bar. The limiting blocks are fixed to both ends of the locking bar. The locking bar is used to install the locking component, the positioning blocks serve a positioning function, the locking screw holes are used to cooperate with bolts to fix the locking component, and the limiting blocks serve to restrict the position of the locking component.

[0012] In a preferred embodiment of this invention, the locking assembly includes a retaining sleeve, a positioning groove, and a connecting hole. The retaining sleeve is fixed to the other end of the first and second protective covers and is fitted onto the locking bar. The positioning groove is located on the inner side of the retaining sleeve and cooperates with the positioning block. The connecting hole passes through the retaining sleeve and is aligned with the locking screw hole and secured by a bolt. By unscrewing the bolt, the first and second protective assemblies can be opened, and the retaining sleeve fixed to the first and second protective covers will detach from the locking bar.

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

[0014] This invention protects the thruster with a protective component, which, together with a crash pad, effectively buffers the impact of collisions. The multiple protective structures significantly reduce the risk of thruster damage. The protective component opens and closes via a hinge, facilitating quick insertion or removal of the thruster. The locking component and the positioning block and positioning groove of the limiting component work together to achieve precise installation. The bolt connection simplifies the disassembly and assembly of the protective component, making it easy to maintain or replace later. The cooperation between the positioning block and the positioning groove ensures the precise installation position of the protective component. The dual limiting effect of bolt fixing and the limiting block effectively prevents the protective component from loosening or shifting during the flight of the UAV, ensuring the continuity of the protective effect.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a drone anti-collision structure, including a drone body 1, a protective component 2, an anti-collision pad 3, a limiting component 4, and a locking component 5.

[0024] The drone body 1 has several support rods 101 mounted on its side. Each support rod 101 has a thruster 102 mounted at its end. A protective component 2 is located outside the thruster 102, a collision pad 3 is located outside the protective component 2, a limiting component 4 is mounted on the support rod 101, and a locking component 5 is mounted on the protective component 2. The protective component 2 is fixed to the limiting component 4 via the locking component 5. The protective component 2 protects the thruster 102, the collision pad 3 provides a collision buffer, and the locking component 5 facilitates the installation and removal of the protective component 2. The thruster 102 includes a motor and a propeller, used for takeoff of the drone body.

[0025] Specifically, the protective assembly 2 includes a first protective cover 201, a second protective cover 202, and a trainer, with a hinge 203 fixed to one end of the first protective cover 201 and the second protective cover 202. The first protective cover 201 and the second protective cover 202, when installed together, protect the thruster 102, providing an anti-collision effect. The hinge 203 connects the first protective cover 201 and the second protective cover 202, allowing them to rotate relative to each other for easy opening and closing.

[0026] Furthermore, both the first protective cover 201 and the second protective cover 202 are semi-circular in shape, and both are made of carbon fiber sheet. When the first protective cover 201 and the second protective cover 202 are combined and installed, they form a complete circular ring, improving the protective effect. The first protective cover 201 and the second protective cover 202, made of carbon fiber sheet, have good impact resistance and are lightweight.

[0027] Furthermore, the anti-collision pad 3 has several pressure relief holes 301 that extend through it. The anti-collision pad 3 is made of rubber. The rubber anti-collision pad 3, in conjunction with the pressure relief holes 301, provides a buffering effect and improves its anti-collision capability.

[0028] Specifically, the limiting component 4 includes a locking bar 401, a positioning block 402, a locking screw hole 403, and a limiting block 404. The locking bar 401 is fixed to the support rod 101. Several positioning blocks 402 are provided and fixed on the outer side of the locking bar 401. The locking screw hole 403 is formed on the side wall of the locking bar 401. The limiting block 404 is fixed at both ends of the locking bar 401. The locking bar 401 is used to install the locking component 5, the positioning block 402 has a positioning effect, the locking screw hole 403 is used to cooperate with bolts to fix the locking component 5, and the limiting block 404 restricts the position of the locking component 5.

[0029] Specifically, the locking assembly 5 includes a retaining sleeve 501, a positioning groove 502, and a connecting hole 503. The retaining sleeve 501 is fixed to the other end of the first protective cover 201 and the second protective cover 202. The retaining sleeve 501 is sleeved on the locking bar 401. The positioning groove 502 is formed on the inner side of the retaining sleeve 501 and cooperates with the positioning block 402. The connecting hole 503 passes through the retaining sleeve 501 and is aligned with the locking screw hole 403 and fixed by bolts. By unscrewing the bolts, the first protective cover 201 and the second protective cover 202 can be opened. After opening, the retaining sleeve 501 fixed on the first protective cover 201 and the second protective cover 202 will detach from the locking bar 401.

[0030] In summary, this UAV collision avoidance structure achieves both collision protection and ease of use through the coordinated action of multiple components. Structurally, the support rod 101 on the side of the UAV body 1 provides a mounting base for the thruster 102, while the protective component 2, through the merging of the first protective cover 201 and the second protective cover 202, encloses the thruster 102 internally to form a protective barrier. The two components are connected by a hinge 203 to allow for rotational opening and closing, facilitating installation and maintenance.

[0031] The limiting component 4 and the locking component 5 work together to fix the protective component 2: the locking bar 401 of the limiting component 4 provides an installation carrier for the locking component 5, and the positioning block 402 and the positioning groove 502 on the inner side of the sleeve 501 are precisely aligned to achieve positioning and prevent the protective component 2 from being installed off-center; after the sleeve 501 is fitted onto the locking bar 401, the connecting hole 503 is aligned with the locking screw hole 403, and the protective component 2 is stably installed on the support rod 101 by bolt fixing, and the limiting block 404 further restricts the position of the sleeve 501 to prevent it from sliding.

[0032] When the drone collides, the outermost anti-collision pad 3 comes into contact with the collision object first. The rubber material itself has elastic deformation capability, and together with the pressure relief hole 301 on it, it can quickly release the impact force and reduce the force transmitted to the protective component 2. The first protective cover 201 and the second protective cover 202 made of carbon fiber resist the remaining impact force with their high strength characteristics, and finally achieve multiple protections for the thruster 102.

[0033] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
