Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to a UAV with a landing gear storage structure. Background Art
[0002] A drone, or unmanned aerial vehicle, is an aircraft controlled by radio remote control or an onboard computer program. It does not require a human pilot and can perform a variety of missions, including military reconnaissance, surveillance, and target strikes. It can also be used in civilian applications such as agricultural plant protection, geographic mapping, disaster monitoring, aerial photography, and express delivery. While the development of drone technology has brought numerous benefits, it has also sparked discussions and regulations regarding privacy, security, and legal issues.
[0003] However, during the use of drones, existing drone landing gear designs often require manual operation on the ground, which not only increases the preparation time before flight, but may also cause safety hazards due to improper operation.
[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a drone with a landing gear storage structure. Utility Model Content
[0005] The purpose of the utility model is to provide a UAV with a landing gear storage structure to solve the problems raised in the above background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A technical solution for a drone with a landing gear storage structure includes a drone body, wings are arranged around the drone body, a landing gear is arranged at the bottom of the drone body, a drive assembly is connected to the top of the landing gear, the drive assembly includes a folding seat, the folding seat is hollow and has a micro motor installed inside, the output end of the micro motor is connected to a driving bevel gear, a connecting shaft is arranged above the driving bevel gear, a transmission bevel gear is sleeved on the connecting shaft, worms are installed at both ends of the connecting shaft, a worm wheel is meshed and connected above the worm, an eccentric connecting rod is installed at an eccentric position on the side of the worm wheel, the tail end of the eccentric connecting rod is connected to a landing gear mounting seat, the landing gear mounting seat is connected to the landing gear, and the landing gear mounting seat is rotatably connected to the folding seat.
[0008] As a preferred technical solution, the worm gear is rotationally connected to the folding seat via a rotating shaft.
[0009] As a preferred technical solution, the worms at both ends of the coupling are distributed in opposite directions so as to drive the two worm wheels to move synchronously towards each other.
[0010] As a preferred technical solution, the landing gear mounting seat and the landing gear are assembled and connected by bolts.
[0011] As a preferred technical solution, the driving bevel gear is meshed with the transmission bevel gear to ensure power transmission.
[0012] As a preferred technical solution, the eccentric connecting rod is rotationally connected to the side wall of the worm gear.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] This utility model provides a drone with a landing gear stowage structure. Driven by a micromotor, the landing gear stowage structure enables automatic stowage and deployment, significantly enhancing the drone's convenience and safety. The motor's rotational power is transmitted to the connecting shaft through the meshing of the drive bevel gear and the transmission bevel gear, thereby driving the rotation of the worm gear at each end. Due to the meshing relationship between the worm and the worm wheel, the worm wheel rotates accordingly. This rotational motion is converted into linear motion of the landing gear mounting base via an eccentric connecting rod, thereby enabling automatic deployment and stowage and folding of the landing gear, improving the drone's overall safety and reliability.

[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution for a drone with a landing gear storage structure: comprising a drone body 1, wings 2 are arranged around the drone body 1, a landing gear 3 is arranged at the bottom of the drone body 1, a driving assembly is connected to the top of the landing gear 3, the driving assembly includes a folding seat 31, the folding seat 31 is hollow, and a micro motor 33 is installed inside, the output end of the micro motor 33 is connected to a driving bevel gear 34, a connecting shaft 35 is arranged above the driving bevel gear 34, a transmission bevel gear 36 is mounted on the connecting shaft 35, the driving bevel gear 34 is meshed with the transmission bevel gear 36 to ensure power transmission, the connecting shaft 35 A worm 37 is installed at both ends. The worms 37 located at both ends of the connecting shaft 35 are distributed in opposite shapes to facilitate driving the two worm gears 38 to move synchronously toward each other. A worm gear 38 is meshed and connected above the worm 37. The worm gear 38 is rotatably connected to the folding seat 31 through a rotating shaft 381. An eccentric connecting rod 39 is installed at an eccentric position on the side of the worm gear 38. The eccentric connecting rod 39 is rotatably connected to the side wall of the worm gear 38. The tail end of the eccentric connecting rod 39 is connected to the landing gear mounting seat 32. The landing gear mounting seat 32 is connected to the landing gear 3. The landing gear mounting seat 32 and the landing gear 3 are assembled and connected by bolts. The landing gear mounting seat 32 is rotatably connected to the folding seat 31.
[0021] Specifically, when the micromotor 33 receives a start signal, it begins to rotate, driving the bevel gear 34 in conjunction with it. Because the bevel gear 34 is tightly meshed with the transmission bevel gear 36, this rotational motion is effectively transmitted to the coupling 35. The coupling 35, a core transmission component, has worms 37 mounted on either end. These worms 37 are designed to be arranged in opposite directions to ensure synchronous and opposite motion of the worm gears 38 on either side.
[0022] As the connecting shaft 35 rotates, the worm gears 37 at each end begin to rotate and mesh with the worm gear 38 above. The worm gear mechanism, with its unique transmission characteristics—a high transmission ratio and self-locking properties—enables stable and reliable rotation of the worm gear 38. As the eccentric connecting rod 39 swings with the rotation of the worm gear 38, the landing gear mounting base 32 connected to its tail end also moves. Because the landing gear mounting base 32 is bolted to the landing gear 3, this movement directly drives the landing gear 3 to deploy or retract.
[0023] The working principle and use process of the utility model: After the utility model is installed, it works according to the above implementation method until all working steps are completed.
[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
