Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle landing gear, in particular to a lightweight folding landing gear for unmanned aerial vehicle. Background Art

[0002] A drone is an aircraft that can fly autonomously or remotely without an operator. A multi-rotor drone is a special unmanned rotorcraft with three or more rotor shafts. With the development and popularization of drones, the landing gear of drones has also become more diverse. The quality of the landing gear of drones also directly affects the stability and safety of drones during takeoff and landing.

[0003] The landing gear of multi-rotor drones on the market is mostly fixed structure, and the aircraft tripod cannot be changed whether in take-off or transport state. The patent application with authorization announcement number CN206511111U discloses a landing gear for drones, including a bilaterally symmetrical sleeve, a support rod and a landing rod. The sleeve is connected to the top of the support rod, and the sleeve can be installed on the aircraft. The landing rod is connected to the bottom of the support rod through a sleeve, and landing balls are symmetrically arranged at both ends of the landing rod; the landing gear is made of carbon fiber material, and the outer layer of the landing ball is made of rubber; when the drone lands on the ground, the landing ball contacts the ground and can slide on the ground, so that the drone can maintain better stability when landing; the landing gear made of carbon fiber material is light in weight and has good mechanical properties, which plays a good buffering role when the drone takes off or lands.

[0004] However, since there is a strict ratio between the wheelbase and the height of the landing gear of a drone, the height of the landing gear must meet certain requirements when the aircraft takes off. The larger the wheelbase, the higher the landing gear height. The fixed landing gear cannot be folded and will take up more volume, which will further affect the volume of the aircraft during storage or transportation and bring extremely invariable. Utility Model Content

[0005] In order to overcome the defect that the landing gear in the prior art cannot be folded, the utility model provides a lightweight folding landing gear for a UAV.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a lightweight folding landing gear for unmanned aerial vehicles, including a fixed support seat and a main body, the upper end of the main body is provided with a mounting groove, the fixed support seat is hinged in the mounting groove at the upper end of the main body through a rotating shaft, a sliding groove connected to the mounting groove is provided in the fixed support seat, a connecting rod is slidably connected in the sliding groove, a spring connected to the connecting rod is provided at the bottom of the sliding groove, a limiting groove and a locking groove matching with the connecting rod are provided on the fixed support seat, a strip groove is provided on the front side of the main body, a dial button connected to the connecting rod is provided in the strip groove, and a tripod is connected to the bottom of the main body.

[0007] As a further improvement of the utility model, a barrel groove is provided at the bottom of the main body, and the tripod is inserted into the barrel groove.

[0008] As a further improvement of the utility model, the tripod is a carbon fiber tube.

[0009] As a further improvement of the utility model, a foot pad is provided at the bottom of the tripod.

[0010] As a further improvement of the utility model, the foot pad is a rubber pad.

[0011] As a further improvement of the present invention, the limiting groove is arranged on the side surface of the fixed support seat, and the locking groove is arranged on the bottom surface of the fixed support seat.

[0012] Compared with the prior art, the utility model has the following beneficial effects: in this solution, the landing gear is designed with folding and unfolding positions. After unfolding, the landing gear will not cause the position of the landing gear to change due to flight or transportation, thereby increasing the reliability of the aircraft during operation; after folding, it will not take up more volume, thereby facilitating the storage or transportation of the UAV.

[0022] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0023] Reference Figures 1 to 7 The embodiment of the utility model discloses a lightweight folding landing gear for a drone, including a fixed support seat 1 and a main body 2. The upper end of the main body 2 is provided with a mounting groove 7. The fixed support seat 1 is hinged in the mounting groove 7 at the upper end of the main body 2 through a rotating shaft 5. A sliding groove 8 connected to the mounting groove 7 is provided in the fixed support seat 1. A connecting rod 10 is slidably connected in the sliding groove 8. A spring 9 connecting the connecting rod 10 is provided at the bottom of the sliding groove 8. A limiting groove 11 and a locking groove 12 matching with the connecting rod 10 are provided on the fixed support seat 1. The limiting groove 11 is provided on the side of the fixed support seat 1, and the locking groove 12 is provided on the bottom of the fixed support seat 1. A strip groove 14 is provided on the front side of the main body 2. A dial button 6 connecting the connecting rod 10 is provided in the strip groove 14. A tripod 3 is connected to the bottom of the main body 2.

[0024] Among them, a foot pad 4 is provided at the bottom of the tripod 3, and the foot pad 4 is a rubber pad, which plays a good buffering role during takeoff or landing, and plays an anti-skid role to make the aircraft takeoff and landing more stable.

[0025] When in use, when the UAV landing gear changes from a folded state to an unfolded state, the button 6 on the front side of the main body 2 is toggled, and the button 6 controls the connecting rod 10 to slide in the slide groove 8. The connecting rod 10 compresses the spring 9, and the end of the connecting rod 10 disengages from the limit groove 11, and the tripod 3 is rotated. After the tripod 3 rotates, the top of the connecting rod 10 is tangent to the arc surface of the fixed support seat 1 and slides. When it is rotated to the unfolded state of the tripod, the button 6 is released, and the connecting rod 10 is reset under the action of the spring 9, so that the top of the connecting rod 10 bounces into the locking groove 12. At this time, the main body 2 is toggled as the force point of the fixed support seat 1, thereby supporting a heavier UAV, and the protrusion at the bottom of the fixed support seat 1 is supported on the fixed support seat 1.

[0026] When the landing gear of the UAV changes from the unfolded state to the folded state, the dial button 6 on the front side of the main body 2 is toggled, and the dial button 6 controls the connecting rod 10 to slide in the slide groove 8. The connecting rod 10 compresses the spring 9, thereby unlocking the end of the connecting rod 10 from the locking groove 12, and rotating the tripod 3. After the tripod 3 rotates, the top end of the connecting rod 10 is tangent to the arc surface of the fixed support seat 1 and slides. When it is rotated to the folded state of the tripod, the dial button 6 is released, and the connecting rod 10 is reset under the action of the spring 9, so that the top end of the connecting rod 10 bounces into the limit groove 11.

[0027] The bottom of the main body 2 is provided with a barrel groove 13, and the tripod 3 is inserted into the barrel groove 13. The tripod 3 is a carbon fiber tube, and the overall design adopts a lightweight design and adopts carbon fiber material, which has high strength and is lighter.

[0028] It should be understood that the specific embodiments described herein are only used to understand the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.
