Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0036] See Figure 1 , Figure 2 This invention provides a hexagonal prism-shaped wave-transparent landing gear, as exemplified by an embodiment of the present invention. Figure 1 , Figure 2 As shown, the landing gear may include:

[0037] A six-way support base 1, the six-way support base 1 includes a central six-way 11, and six first transverse carbon tubes 12 are evenly distributed along its circumference; each of the first transverse carbon tubes 12 is provided with a mounting bracket 13 and a landing gear mounting bracket 14.

[0038] The landing gear body 2 includes six longitudinal carbon tubes 21, six second transverse carbon tubes 22, and six bottom tees 23. The six second transverse carbon tubes 22 are connected by the six bottom tees 23 to form a closed hexagonal structure. The lower ends of the six longitudinal carbon tubes 21 are respectively connected to the longitudinal connection ports of the six bottom tees 23. The lower ends of the six longitudinal carbon tubes 21 are respectively connected to the landing gear mounting seats 14 on the six first transverse carbon tubes 12, so that the interior of the landing gear body 2 forms a hexagonal prism-shaped load-bearing space.

[0039] The shock-absorbing mounting device 3 includes six load adapters 31, six shock absorbers 32, and a load adapter plate 33. The six load adapters 31 are respectively connected to the mounting seats 13 on the six first transverse carbon tubes 12, the six shock absorbers 32 are respectively connected to the six load adapters 31, and the load adapter plate 33 is respectively connected to the six shock absorbers 32.

[0040] To facilitate wiring, this embodiment of the application may also provide an internal hollow space for the central six-way connector 11 to form a connection and maintenance space. The six-way support base 1 also includes a six-way lower cover plate 15.

[0041] A mounting shim 34 is provided at the connection position between the load transfer plate 33 and the shock absorber 32.

[0042] To facilitate installation with the wing, embodiments of this application may also provide an arm folding assembly 4 at the distal end of each of the first transverse carbon tubes 12.

[0043] To enhance anti-collision performance, embodiments of this application may also provide anti-collision foam 24 on both the longitudinal carbon tube 21 and the second transverse carbon tube 22.

[0044] In order not to affect the detection accuracy and signal stability of radar and other payloads, the embodiments of this application may also provide that the first transverse carbon tube 12, the longitudinal carbon tube 21 and the second transverse carbon tube 22 are all made of aramid material, and the bottom tee 23 is made of nylon and glass fiber material.

[0045] To further improve the strength of the landing gear body 2, this embodiment of the application can provide a landing gear reinforcement support 5, which is located inside the landing gear body 2 and connected to the six longitudinal carbon tubes 21; the landing gear reinforcement support 5 is used to limit the deformation and swaying of the landing gear body 2 in two directions on the horizontal plane.

[0046] Furthermore, the landing gear reinforcement support 5 is fixed at a position above two-thirds of the height of the longitudinal carbon tube 21. Specifically, the landing gear reinforcement support 5 includes two first tee joints 51, two second tee joints 52, four third tee joints 53, two first auxiliary support carbon tubes 54, two second auxiliary support carbon tubes 55, and two third auxiliary support carbon tubes 56.

[0047] The hexagonal prism-shaped radar-transparent landing gear provided in this application greatly increases the load space for landing gear of the same volume. The landing gear parts are made of radar-transparent materials: aramid and nylon with glass fiber, which will not affect the detection accuracy and signal stability of radar and other loads.

[0048] The hexagonal prism-shaped wave-transparent landing gear provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 , Figure 2 As shown, the hexagonal prism-shaped wave-transparent landing gear includes an arm folding assembly 4, a six-way support 1, a shock-absorbing mounting device 3, a landing gear reinforcement support 5, and a landing gear body 2.

[0050] The arm folding assembly 4 includes an arm folding component, which is fixedly connected to the landing gear body 2. The six-way support 1 consists of a central six-way 11, a six-way lower cover plate 15, and six mounting seats 13 for fixing the upper UAV central cabin components, etc. A first transverse carbon tube 12 connects to the central six-way 11, is connected in series with the mounting seats 13, and is connected to the folding component. The shock-absorbing mounting device 3 consists of a load converter 31 connected in series with the first transverse carbon tube 12, a shock absorber 32, a load converter plate 33, and a converter plate mounting gasket 34. The landing gear reinforcement support 5 consists of a first tee 51, a second tee 52, a third tee 53, a first auxiliary support carbon tube 54, a second auxiliary support carbon tube 55, and a third auxiliary support carbon tube 56. The landing gear body 2 consists of six longitudinal carbon tubes 21, a second transverse carbon tube 22, a bottom tee 23, and anti-collision foam 24.

[0051] like Figure 3 As shown, the boom assembly is connected to the boom folding component via a latch, enabling the boom to unfold and fold. The landing gear mounting base 14 is located directly below the boom folding component, providing the strongest possible fixed support for the boom while maximizing space for the centrally mounted load.

[0052] like Figure 4 As shown, the central six-way connector 11 connected in series with the first transverse carbon tube 12 and the six mounting brackets 13 form a plane, which serves as the mounting plane for the upper center compartment and power compartment of the UAV. The hollow part in the center of the central six-way connector 11 can provide a certain space for connection, wiring and maintenance. The lower cover plate 15 of the six-way connector is pressed with the central six-way connector 11 by screws, which can ensure the electromagnetic compatibility of the UAV system to a certain extent. The presence of the first transverse carbon tube 12 can ensure the flatness requirements of the central six-way connector 11 and the six mounting brackets 13, and provide a certain rigidity support for the upper center compartment and power compartment of the landing gear.

[0053] like Figure 5 As shown, the load suspended at the center of the landing gear is connected to the landing gear through the load adapter 31, shock absorber 32, load adapter plate 33, and adapter plate mounting shim 34. The inverted shock absorber 32 can provide the load with a wide range of three-dimensional high damping impact resistance.

[0054] like Figure 6As shown, the landing gear reinforcement support 5 consists of two first tees 51, two second tees 52, four third tees 53, two first auxiliary support carbon tubes 54, two second auxiliary support carbon tubes 55, and two third auxiliary support carbon tubes 56. It can fix the deformation and swaying of the landing gear body 2, which is composed of six longitudinal carbon tubes 21, in two directions on the horizontal plane. The landing gear reinforcement support 5 is fixed above two-thirds of the height of the longitudinal carbon tubes 21, ensuring reinforcement while saving considerable internal mounting space in the landing gear. Considering the wave transmission requirements of the load and the required strength and stiffness, the auxiliary support carbon tubes of the landing gear reinforcement support 5 are made of aramid material, and the tees are made of nylon with glass fiber reinforcement.

[0055] like Figure 7 As shown, six longitudinal carbon fiber tubes 21, six second transverse carbon fiber tubes 22, and a bottom tee 23 together form the landing gear body 2 frame. The anti-collision foam 24 on the longitudinal carbon fiber tubes 21 buffers the impact of the motor mount on the longitudinal carbon fiber tubes 21 after the arm is folded. The anti-collision foam 24 on the second transverse carbon fiber tubes 22 buffers the impact of the UAV on the ground during landing. Similarly, to ensure the wave-transmitting properties of the landing gear body 2 and the required strength of the landing gear itself, the longitudinal carbon fiber tubes 21 and the second transverse carbon fiber tubes 22 are made of aramid material, and the bottom tee 23 is made of nylon with glass fiber reinforcement.

[0056] The landing gear configuration is shown in the diagram. Figure 7 As shown, compared to the traditional four-sided pyramidal landing gear structure, such as Figure 8 As shown, within the same volume range, this landing gear can carry a larger volume load and form a more stable support.

[0057] In summary, the hexagonal prism-shaped wave-transparent landing gear provided in this application, compared to the traditional quadrilateral landing gear, can carry a larger load within the same volume and has higher stability; the main body of the landing gear below uses wave-transparent material while ensuring strength, which can meet the wave-transparency requirements of the load. Furthermore, actual verification has shown that this landing gear can meet the strength requirements for carrying a 35KG load and during takeoff and landing.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0059] As can be seen from the above description of the embodiments, those skilled in the art can clearly understand that this application can be implemented by means of software plus necessary general-purpose hardware platforms. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product.

[0060] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, for system or system embodiments, since they are basically similar to method embodiments, the description is relatively simple, and relevant parts can be referred to the descriptions in the method embodiments.
