Description

Technical Field

[0001] The utility model relates to the technical field of plant protection UAVs, and in particular to a lightweight shell of a plant protection UAV. Background Art

[0002] A plant protection drone primarily consists of a flight platform, control system, power system, and spraying or seeding system. The flight platform serves as the foundation for each module, providing a framework for the various systems and providing mounting interfaces for the power system, control system, spraying system, and onboard equipment. The chassis protects the internal modules from water and dust.

[0003] Existing agricultural drone casings have shortcomings such as numerous parts, heavy weight, and complex wiring. Furthermore, to facilitate assembly and maintenance of internal components, the drone casing is composed of a removable upper and lower shells. These are typically secured with bolts, resulting in inefficient assembly and disassembly, hindering maintenance and ease of operation. Furthermore, in existing technology, most peripheral components used in conjunction with the drone casing assembly are secured to the casing via brackets, which increases the drone's weight, hindering its portability and ensuring long-range flight.

[0004] In view of the above-mentioned defects, a lightweight shell of a plant protection UAV is provided. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problem and to propose a lightweight shell for a plant protection drone.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a lightweight housing for a plant protection drone, comprising a metal frame, an upper shell and a lower shell constituting the drone housing being fixed to the metal frame, and peripheral components being mounted on the lower shell;

[0007] The upper shell and the lower shell are fixed by a snap-fit structure. A wiring harness is arranged inside the lower shell. A mounting seat is fixed through the lower shell by a snap-fit structure. An antenna is screwed and connected to the outer side of the mounting seat.

[0008] Preferably, the peripheral components are directly fixed to the lower shell by bolts, and the lower shell is formed with ribs at positions for fitting the peripheral components, and the peripheral components include a gimbal and a radar.

[0009] Preferably, the snap-fit structure includes a male buckle fixed at the lower edge of the upper shell, and a female buckle that cooperates with the male buckle is fixed at the upper edge of the lower shell.

[0010] Preferably, the snap-fitting end of the male buckle is a spherical structure, and an arc-shaped groove that fits the spherical structure is formed in the female buckle. The end of the female buckle is formed with an inclined surface. During the docking process of the upper shell with the lower shell, the snap-fitting end of the male buckle drives the female buckle to open by pressing the inclined surface until the male buckle is embedded in the arc-shaped groove, thereby completing the assembly of the upper shell and the lower shell.

[0011] Preferably, a cavity is formed in the lower shell to match the arrangement of the wiring harness, and a wire sealing ring is fixed in the cavity to match the wiring harness passing through.

[0012] Preferably, the wire-passing sealing ring is made of rubber, and when the wire harness passes through the wire-passing sealing ring, the wire-passing sealing ring is tightly wrapped around the outside of the wire harness.

[0013] Preferably, the clamping structure includes a notch formed through the upper shell, a retaining ring is fixed in the notch, and an annular groove for the retaining ring to press into is formed at the inner end of the notch.

[0014] Preferably, a buckle ring capable of passing through the retaining ring is formed on the outer wall of the mounting seat, and the end surfaces where the buckle ring and the retaining ring slide against each other form a slope structure.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this application, through the setting of the snap-fit structure, after completing the fixation of the lower shell and the metal frame, the male buckle is aligned with the female buckle, and then the upper shell and the lower shell are pressed together. When the snap-fit end of the male buckle passes through the female buckle, the female buckle will restore its deformation and tighten its opening, thereby limiting the male buckle from slipping outward, and facilitating the operation of the user while ensuring the stability of the docking of the lower shell and the upper shell.

[0017] 2. In this application, the wire sealing ring is made of rubber. When the wire harness passes through the wire sealing ring, the wire sealing ring is tightly wrapped around the outside of the wire harness. The wire harness passes through the wire sealing ring in the space of the lower shell and is connected to the drone arm, thereby protecting the electronic components and circuits inside the drone from the intrusion of moisture and other impurities, thereby achieving the protection purpose.

[0018] 3. In this application, the gimbal and radar are directly fixed to the lower shell by bolts, eliminating other plastic parts such as brackets, making the drone shell lightweight. By setting the ribs, the strength and rigidity of the product can be improved without increasing the wall thickness of the product, thereby saving materials, reducing weight and reducing costs, making it easier for users to carry while improving the drone's endurance.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-8 The utility model provides a technical solution: a lightweight shell of a plant protection drone, including a metal frame 1, an upper shell 2 and a lower shell 3 constituting the drone shell are fixed on the metal frame 1, and peripheral parts are installed on the lower shell 3.

[0031] A drone's metal frame is a crucial component of its structure. It typically needs to be lightweight, high-strength, and corrosion-resistant to meet the drone's performance requirements during flight. Common materials for drone metal frames include aluminum alloys and titanium alloys, which are widely used for their lightweight and high-strength properties.

[0032] Drone peripherals can enhance the functionality of the drone, improve flight safety, enhance the user experience, or facilitate portability and storage.

[0033] The upper shell 2 and the lower shell 3 are fixed by a snap-fit structure. A wiring harness 9 is arranged inside the lower shell 3. A mounting base 10 is fixed through the lower shell 3 by a snap-fit structure. The outer side of the mounting base 10 is screwed and connected to the antenna 11.

[0034] The lower shell 3 is fixed to the metal frame 1 with bolts to ensure the stability of the drone shell relative to the metal frame 1. Under the premise of ensuring the safe and stable assembly of the lower shell 3, the upper shell 2 and the lower shell 3 are fixed together by a snap-fit structure, achieving the purpose of facilitating the assembly of the drone shell.

[0035] The antenna 11 is a key component in the drone communication system, responsible for transmitting and receiving electromagnetic waves to enable communication between the drone and the ground control station or other drones. The setting of the snap-on structure also facilitates the assembly of drone accessories and is convenient for users to assemble and use.

[0036] The wiring harness 9 is a very important component of the drone. It is responsible for connecting various components on the drone, such as the engine, sensors, batteries, etc., to achieve power and signal transmission.

[0037] Specifically, such as Figure 3 and Figure 4 As shown, the peripheral components are directly fixed to the lower shell 3 by bolts, and the lower shell 3 is formed with ribs at positions for fitting the peripheral components. The peripheral components include a pan-tilt head 4 and a radar 5.

[0038] The peripheral components are directly fixed to the lower shell 3 by bolts, eliminating the need for brackets and making the drone shell lighter.

[0039] Ribs, also known as reinforcing ribs, can increase the strength and rigidity of the product without increasing the wall thickness, thereby saving material, reducing weight, and lowering costs. The provision of ribs enhances the stable and secure placement of peripheral components relative to the lower shell 3.

[0040] The gimbal 4 is used to mount and secure payloads such as cameras, ensuring stable camera footage and precise pointing and tracking during flight. The radar 5 is specifically designed to detect and track drones, enabling automatic obstacle avoidance and reducing the risk of operational errors.

[0041] Specifically, such as Figure 6 As shown, the snap-fit structure includes a male snap 6 fixed to the lower edge of the upper shell 2, and a female snap 7 fixed to the upper edge of the lower shell 3 to engage with the male snap 6. The snap-fitting end of the male snap 6 is spherical, and the female snap 7 is formed with an arcuate groove that engages with the spherical structure. The end of the female snap 7 is formed with an inclined surface. During the docking process between the upper shell 2 and the lower shell 3, the snap-fitting end of the male snap 6 presses on the inclined surface, forcing the female snap 7 to open until the male snap 6 fits into the arcuate groove, completing the assembly of the upper shell 2 and the lower shell 3.

[0042] After completing the fixation of the lower shell 3 and the metal frame 1, align the male buckle 6 fixed on the bottom of the upper shell 2 with the female buckle 7 on the top of the lower shell 3, and then press the upper shell 2 and the lower shell 3 together so that the snapping end of the male buckle 6 acts on the inclined surface of the female buckle 7, causing the female buckle 7 to open outward. When the snapping end of the male buckle 6 passes through the female buckle 7, the female buckle 7 will restore its deformation and tighten its opening, thereby limiting the male buckle 6 from slipping outward, and facilitating the operation of users while ensuring the docking stability of the lower shell 3 and the upper shell 2.

[0043] Specifically, such as Figure 4 As shown, a cavity is formed in the lower shell 3 to match the arrangement of the wiring harness 9, and a wire sealing ring 8 is fixed in the cavity to match the wiring harness 9 passing through;

[0044] The cable gland 8 is made of rubber. When the wiring harness 9 passes through it, it tightly wraps around the outside of the harness 9. The harness 9 passes through the gland within the space of the lower housing 3 and connects to the drone arm. This protects the drone's internal electronic components and wiring from moisture and other impurities, eliminating other plastic components like brackets, achieving lightweight design and facilitating maintenance. The drone's cable gland 8 needs to possess excellent chemical, temperature, and pressure resistance to adapt to diverse operating environments.

[0045] Specifically, such as Figure 5 and Figure 6 As shown, the clamping structure includes a notch 201 formed through the upper shell 2, a retaining ring 202 is fixed in the notch 201, and an annular groove is formed at the inner end of the notch 201 to fit the retaining ring 202.

[0046] When fixing the mounting base 10 , the mounting base 10 needs to be passed through the slot 201 from the inside to the outside. When the retaining ring 202 is embedded in the annular groove, the mounting base 10 can be fixed. At this time, the antenna 11 can be screwed and fixed on the outside of the mounting base 10 .

[0047] The outer wall of the mounting base 10 is formed with a retaining ring 1001 that can pass through the retaining ring 202. The end surfaces of the retaining ring 1001 and the retaining ring 202 that slide against each other form a sloped structure. After the retaining ring 202 passes through the retaining ring 1001, the end surfaces of the retaining ring 202 and the retaining ring 1001 that abut against each other form a flat structure, thereby preventing the retaining ring 202 from sliding out of the annular groove. The sloped structure is a common design that allows two components to slide and abut more smoothly during connection, reducing friction and wear. It can also help provide a certain degree of guidance during assembly or disassembly.

[0048] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
