Technical Field

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

[0002] UAV aircraft are widely used in many fields due to their advantages such as maneuverability, quick response, unmanned flight and low operating requirements. The UAV industry is developing rapidly. The UAV landing gear is generally fixed at the bottom of the UAV fuselage to support the UAV fuselage upward. It is an important component that can ensure the safe landing and take-off stability of the UAV.

[0003] During the landing process of a drone, its landing gear needs to withstand the corresponding impact force. The traditional landing gear has a fixed structure, and the impact of long-term use will have a certain impact on the structural strength, and the buffering effect cannot be adapted to drones of different weights. Therefore, we propose a drone landing gear. Utility Model Content

[0004] The purpose of the utility model is to provide a landing gear for an unmanned aerial vehicle (UAV). A support rod is arranged below a base plate, and a connecting rod is fixed above the support rod and passes through the top of the base plate. A spring between the two can provide a buffering force between the support rod and the base plate, thereby protecting the structure. The compression degree of the spring is variable, thereby changing the hardness of the spring to meet the use of UAVs of different weights, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of UAV landing gear, including a base plate and a support rod, the support rod is arranged below the base plate, and both ends of the support rod are bent upwards; connecting rods are vertically fixed on both sides of the surface of the support rod, and the connecting rod can slide through the top of the base plate, and the outer ring of the connecting rod above the base plate is screwed with a nut, and the nut is in contact with the surface of the base plate, and a spring is sleeved on the outer ring of the connecting rod between the base plate and the support rod; a rubber sheet is attached to the bottom of the support rod, and a clamping strip is integrally connected to the top of the rubber sheet, and the clamping strip is inserted into a clamping slot opened at the bottom of the support rod.

[0006] By adopting the above technical solution, the structure is installed on both sides of the bottom of the drone using the perforations on the surface of the mounting rod. The degree of compression of the spring is changed by turning the nut, thereby changing its hardness and softness, making it suitable for use with drones of different weights. The rubber sheet at the bottom can also provide protection and reduce wear.

[0007] Optionally, a thread is arranged around the upper outer ring of the connecting rod, and the nut is screwed to the outer ring of the connecting rod through the thread.

[0008] By adopting the above technical solution, the nut is screwed onto the outer ring of the connecting rod through the thread of the outer ring of the connecting rod.

[0009] Optionally, a limit plate is fixed to the top of the connecting rod, and the limit plate is fixed to the top of the connecting rod by welding.

[0010] By adopting the above technical solution, the limiting plate can prevent the nut from slipping due to being twisted upward.

[0011] Optionally, mounting rods are vertically fixed on both sides of the surface of the base plate, and the mounting rods are perpendicular to the surface of the base plate.

[0012] By adopting the above technical solution, the bottom plate is fixed to the bottom of the drone using the mounting rods on both sides of the bottom plate.

[0013] Optionally, a through hole is formed on the top surface of the mounting rod, and the through hole passes through the top of the mounting rod.

[0014] By adopting the above technical solution, the bolts connecting the mounting rod and the drone can pass through the top of the mounting plate through the perforation.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The technical solution of the present application sets a support rod below the base plate, and fixes a connecting rod above the support rod that passes through the top of the base plate. The spring between the two can provide a buffering force between the support rod and the base plate, thereby protecting the structure. The compression degree of the spring is variable, thereby changing the hardness of the spring to meet the needs of drones of different weights.

[0017] 2. The technical solution of the present application fixes the rubber sheet at the bottom of the support rod by inserting the upper clamping strip into the clamping slot, so that the rubber sheet can be easily removed and the severely worn rubber sheet can be replaced.

[0022] See also Figure 1-2The utility model provides a technical solution: a UAV landing gear, including a base plate 1 and a support rod 2, mounting rods 11 are vertically fixed on both sides of the surface of the base plate 1, the mounting rods 11 are perpendicular to the surface of the base plate 1, the mounting rods 11 on both sides have the same length, and a through hole 111 is opened on the top surface of the mounting rod 11, the through hole 111 passes through the top of the mounting rod 11, and a bolt can pass through the through hole 111 to pass through the top of the mounting rod 11, and then connect with the UAV to achieve the installation and fixation of the base plate 1.

[0023] The support rod 2 is arranged below the base plate 1, and both ends of the support rod 2 are bent upward, and connecting rods 3 are vertically fixed on both sides of the surface of the support rod 2, and the connecting rod 3 can slide through the top of the base plate 1, and the upper outer ring of the connecting rod 3 is evenly surrounded by threads 32. The outer ring of the connecting rod 3 above the base plate 1 is screwed with a nut 34 through the thread 32, and the nut 34 is in contact with the surface of the base plate 1. A spring 31 is sleeved on the outer ring of the connecting rod 3 between the base plate 1 and the support rod 2, and the two ends of the spring 31 are respectively in contact with the bottom surface of the base plate 1 and the upper surface of the support rod 2. When the nut 34 is twisted up and down, the length of the spring 31 can be changed to change its soft and hard state, and its buffering effect can be changed to ensure the adaptation to drones of different weights. A limiting plate 33 is fixed on the top of the connecting rod 3, and the limiting plate 33 is fixed to the top of the connecting rod 3 by welding. The limiting plate 33 can limit the nut 34 to prevent it from being screwed off from the top.

[0024] A rubber sheet 4 is attached to the bottom of the support rod 2, and a clamping strip 41 is integrally connected to the top of the rubber sheet 4. A clamping groove 21 is opened on the bottom surface of the support rod 2, and one end of the clamping groove 21 is connected to the outside, so that the clamping strip 41 is inserted into the clamping groove 21 through the through end, so as to achieve the purpose of sticking the rubber sheet 4 to the bottom surface of the support rod 2. The support rod 2 contacts the ground through the rubber sheet 4, which protects the surface of the support rod 2, and the rubber sheet 4 can be removed and replaced when it is severely worn.

[0025] When in use, the mounting rod 11 is passed through the connecting bolt through the perforation 111 on the top thereof, and then the mounting rod 11 is fixed to the bottom of the drone by the connecting bolt. The bottom plate 1 and other structures are installed under both sides of the drone. Before use, the degree of compression of the spring 31 is adjusted according to the weight of the drone. When the drone is light, the nut 34 is screwed upward and the degree of compression of the spring 31 is relatively low. When landing, the support rod 2 first touches the ground. The spring 31 with a low degree of compression can provide a sufficiently light and slow-descent buffering effect for the light drone, ensuring a smooth landing; and when the drone is heavy, the nut 34 is screwed downward and the degree of compression of the spring 31 is relatively high. When landing, the support rod 2 first touches the ground. The spring 31 with a high degree of compression can provide a more stable buffering effect for the heavier drone, ensuring a smooth landing. The bottom of the support rod 2 touches the ground through the rubber sheet 4, which has a protective effect on the bottom of the support rod 2, and the card strip 41 above the rubber sheet 4 can be pulled out from the card slot 21, which is convenient for replacing the rubber sheet 4 with severe wear.
