[0002] A drone is an aircraft that can fly without a human on board. It generally refers to a multi-rotor aircraft that can take off and land autonomously and navigate autonomously through remote control or autonomous flight control systems. Currently, drones are widely used in commercial, entertainment, and agricultural fields, covering a variety of uses such as aerial photography, cargo transportation, agricultural monitoring, and search and rescue.

[0003] Usually, drones are equipped with landing gear, which is a structure used to protect the drone when taking off or landing on the ground. Generally speaking, the landing gear is fixedly installed on the bottom of the drone. Although the landing gear can play a protective role, it is one of the important factors that increase the size of the drone when the drone is stored or transported. In response to this, technicians in this field have proposed a folding landing gear, but due to the introduction of a folding structure, the stability of the landing gear is often reduced when it is in use, and the landing gear is prone to accidental folding.

[0004] Therefore, it is necessary to develop a new UAV landing gear to solve the technical problem that the portability and stability of the UAV landing gear in the prior art are difficult to maintain at the same time. Utility Model Content

[0005] The utility model aims to provide a drone and a drone landing gear to solve the technical problem in the prior art that the portability and stability of the drone landing gear are difficult to maintain at the same time.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A drone landing gear comprises a base, on which a plurality of landing assemblies are mounted, wherein the landing assemblies comprise a first landing support and a second landing support which are spaced apart from each other;

[0008] A storage seat is installed on the base between the first landing bracket and the second landing bracket; a first storage position is formed between the storage seat and the base, and a second storage position is provided on a side of the storage seat away from the base;

[0009] The landing assembly is configured with a landing state and a storage state; when the landing assembly is in the storage state, the first landing support is located at the first storage position, and the second landing support is located at the second storage position.

The first storage support portion and the second storage support portion are respectively abutted against the base.

[0012] Optionally, a first arc-shaped guide groove is provided on the base at a position corresponding to the landing assembly, and a first bolt and a second bolt are passed through the first guide groove;

[0013] The head of the first bolt is located at one side of the base, the rod of the first bolt passes through the first guide groove and the first landing bracket, and is bolted with a first nut;

[0014] The head of the second bolt is located at one side of the base, the rod of the second bolt passes through the first guide groove and the second landing bracket, and is threadedly connected with a second nut.

[0015] Optionally, the first storage support portion, the second storage support portion and the storage extension portion are respectively provided with second guide grooves at positions corresponding to the first guide grooves;

[0037] Embodiment 1:

[0038] The drone landing gear provided in this embodiment is applied to a drone to provide support and protection for the drone during landing and take-off. In this embodiment, the structure of the drone landing gear is improved to enable it to have a certain degree of retractability while maintaining the stability of the drone during take-off or landing.

[0039] like Figures 1 to 3 As shown, the drone landing gear in this embodiment includes a base 10, on which are mounted a plurality of landing assemblies 20, the landing assemblies 20 including a first landing support 21 and a second landing support 22 arranged at intervals; wherein the landing support is a cantilevered arc-shaped arm, capable of providing support for the drone. A storage seat 30 is mounted on the base 10 between the first landing support 21 and the second landing support 22; a first storage position is formed between the storage seat 30 and the base 10, and a second storage position is provided on the side of the storage seat 30 away from the base 10.

[0040] The lifting assembly 20 is configured with a lifting state and a storage state; Figure 1 As shown, when the landing assembly 20 is in the landing state, on the base 10, the first landing support 21, the storage seat 30 and the second landing support 22 are sequentially arranged at intervals; Figure 2 As shown, when the landing assembly 20 is in the stowed state, the first landing gear 21 is located at the first stowed position, and the second landing gear 22 is located at the second stowed position. At this time, the first landing gear 21 and the second landing gear 22 are equivalent to being stacked on the base 10, thereby improving the stowability of the UAV landing gear.

[0041] Specifically, the landing gear of the UAV in this embodiment has a landing assembly 20 that can switch between a storage state and a retracted state. When in the landing state, each landing support is independently arranged to protect and support the UAV; when in the retracted state, by moving the first landing support 21 and the second landing support 22, the first landing support 21 is located at the first storage position, and the second landing support 22 is located at the second storage position, that is, located on both sides of the storage seat 30. The first landing support 21 and the second landing support 22 are equivalent to being stacked on the base 10, thereby being equivalent to stacking the two landing supports together, thereby making the UAV more compact when stored. At the same time, when in the landing state, each landing support is still independently arranged and directly installed on the base 10, and there will be no accidental folding, which has the advantage of high stability. It can be understood that the UAV landing gear in this embodiment achieves improved storability by directly overlapping and stacking two landing brackets, without the need to fold the landing brackets themselves. Therefore, the UAV and UAV landing gear in this embodiment can improve portability while maintaining stability.

[0042] Furthermore, if Figure 3 As shown, the storage seat 30 includes a storage base 33 mounted on the base 10, and a storage extension portion 34 is extended outward from the storage base 33, that is, the storage extension portion 34 is at least partially suspended, and a first storage position is formed between the storage extension portion 34 and the base 10; one end of the storage extension portion 34 is connected to the first storage support portion 31, and the other end of the storage extension portion 34 is connected to the second storage support portion 32, and the first storage support portion 31 and the second storage support portion 32 are respectively abutted on the base 10. It can be understood that through the above arrangement, the three-point support form is adopted, so that the stability of the storage seat 30 is improved.

[0043] Furthermore, if Figures 3 to 6 As shown, a first arc-shaped guide groove 101 is opened on the base 10 at a position corresponding to the landing assembly 20, and a first bolt (not shown) and a second bolt (not shown) are passed through the first guide groove 101; the head of the first bolt is located at one side of the base 10, the rod of the first bolt passes through the first guide groove 101 and the first landing bracket 21, and is bolted with a first nut (not shown); the head of the second bolt is located at one side of the base 10, the rod of the second bolt passes through the first guide groove 101 and the second landing bracket 22, and is threadedly connected with a second nut (not shown).

[0044] It should be pointed out that when the nut is loosened, the screw rod can move along the first guide groove 101, so that the user can change the position of the landing gear. After the position of the landing gear is confirmed, the user can tighten the nut again, and the landing gear and the base 10 are sandwiched between the nut and the head of the bolt, so that the landing gear is abutted against the base 10. Through the above arrangement, the position of the landing gear can be flexibly adjusted.

[0045] Furthermore, the first storage support portion 31, the second storage support portion 32 and the storage extension portion 34 are respectively provided with a second guide groove 35 corresponding to the position of the first guide groove 101; the first storage support portion 31 and the second storage support portion 32 are respectively rotatably connected to the storage extension portion 34, and the end portion of the first storage support portion 31 and the end portion of the second storage support portion 32 are respectively movably connected to the base 10.

[0046] Among them, magnetic blocks are respectively installed at the ends of the first storage support part 31 and the ends of the second storage support part 32, and magnetic suction parts are installed at the positions corresponding to the magnetic blocks on the base 10. The magnetic blocks can be magnetically connected to the magnetic suction parts, and the magnetic suction parts can be structures that can be magnetically attracted, such as armatures.

[0047] In order to facilitate understanding by those skilled in the art, the process of switching the landing assembly 20 from the landing state to the stowed state is described below:

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, the initial first landing bracket 21 and the second landing bracket 22 are located on both sides of the storage seat 30; then, the nut on the first landing bracket 21 is loosened so that the first landing bracket 21 can move, and then, in the direction away from the base 10, the magnetic force on the first storage support portion 31 is overcome, and the first storage support portion 31 is lifted, so that the first landing bracket 21 can move to between the storage extension portion 34 and the base 10 (the first storage position), and then the nut is tightened again. At this time, the first landing bracket 21 and the base 10 are pressed between the nut and the head of the first bolt, and the end of the first storage support portion 31 is magnetically connected to the base 10 again; at this time, the first landing bracket 21 enters between the base 10 and the storage extension portion 34;

[0049] like Figure 3 , Figure 5 and Figure 6As shown, the nut on the second landing bracket 22 is loosened so that the second landing bracket 22 can move. Then, the second landing bracket 22 is moved to the storage base 33 along the first guide groove 101 and the second guide groove 35. It should be pointed out that since its nut needs to be moved from the bottom of the first guide groove 101 to the bottom of the second guide groove 35, the first guide groove 101 is provided with an avoidance groove 102 at the projection position of the second guide groove 35. When the second landing bracket 22 moves upward along the second storage support portion 32, its nut can pass through the avoidance groove 102 and move to the bottom of the second guide groove 35. After the second landing bracket 22 moves to the storage extension portion 34, the nut is tightened again so that the second landing bracket 22 and the storage extension portion 34 are pressed between the nut and the head of the second bolt, thereby locking the second landing bracket 22 on the storage extension portion 34. In addition, an avoidance hole is provided at the position of the storage extension portion 34 corresponding to the nut to avoid the movement of the nut. Through the above setting, there is no need to remove parts from the drone landing gear, which effectively prevents the loss of parts and has an anti-fool function.

[0050] On the basis of the above embodiment, the first landing bracket 21 and the second landing bracket 22 are respectively provided with two waist-shaped holes 23 corresponding to the positions of the first guide groove 101 .

[0051] On the basis of the above embodiment, there are two groups of landing assemblies 20, and the two groups of landing assemblies 20 are symmetrically arranged.

[0052] In summary, the UAV landing gear provided in this embodiment improves portability while maintaining stability and also has the advantages of high flexibility.

[0055] In summary, the drone provided in this embodiment improves portability while maintaining take-off and landing stability, and also has the advantages of high flexibility.

[0056] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
