Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a truss-type UAV frame. Background Technology

[0002] A truss structure is a type of structure consisting of members connected to each other at both ends by hinges. These members primarily bear axial forces, including tension and compression. Mechanically, it is a very efficient load-bearing structure, capable of supporting large external loads with a relatively light self-weight through proper member arrangement and connection methods.

[0003] However, existing technologies have at least the following technical problems: When existing drones are in use, the unbalance caused by changes in rotor lift can generate very large torsional forces on the arms. If the body strength is insufficient or the connection strength between the body and the arms is insufficient, the drone will twist and deform, seriously affecting flight attitude and flight control, and even causing a crash. In addition, existing drones are prone to damage upon landing due to the poor performance of the bottom cushioning components, which cannot effectively protect the drone. Therefore, we provide a truss-type drone frame. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a truss-type drone frame, which solves the following problems: When existing drones are in use, the unbalance caused by changes in rotor lift leads to very large torsional forces on the arms. If the body strength is insufficient, or the connection strength between the body and the arms is insufficient, the drone will twist and deform, seriously affecting flight attitude and flight control, and even causing crashes. In addition, existing drones suffer from poor bottom cushioning components upon landing, which can lead to damage to the body and cannot effectively protect the drone.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A truss-type drone frame includes a drone body. Two sets of buffer components are provided at the bottom of the drone body. Each buffer component is fixedly connected to a support foot at its bottom. Multiple connecting rods are fixedly connected to the outside of the drone body. One end of each connecting rod is movably connected to a rotor connector.

[0009] Preferably, the rotor connectors are fixedly connected by connecting members.

[0010] The technical effect of adopting the above-mentioned further solution is that the connecting member mainly bears axial force, including tension and compression, which enables the rotor connecting member to withstand larger external loads.

[0011] Preferably, a reinforcing member is fixedly connected between the connecting member and the connecting rod.

[0012] The technical effect of adopting the above-mentioned further solution is that strengthening the tie can stabilize and support the connecting tie, thereby improving the stability of the connecting tie during use.

[0013] Preferably, the shape formed by the connecting tie, the connecting rod and the reinforcing tie is triangular.

[0014] The technical effect of adopting the above-mentioned further solution is that the triangular structure makes the reinforcing tie, connecting tie and rotor connecting parts more stable.

[0015] Preferably, the connecting tie and the reinforcing tie are made of carbon fiber material.

[0016] The technical effect of adopting the above-mentioned further solutions is that carbon fiber materials have the advantages of being lightweight and having high strength.

[0017] Preferably, the buffer assembly includes four connecting columns located at the bottom of the UAV body. A rotating shaft is rotatably connected to each opposite side of the connecting column. A connecting plate is fixedly connected to the outside of each rotating shaft. A first connecting plate is fixedly connected to one side of the connecting plate. A damper is fixedly installed on one side of the first connecting plate. A second connecting plate is fixedly connected to one end of the damper. A connecting block is fixedly connected to one side of the second connecting plate. A rectangular column is rotatably connected to one side of the connecting block. The bottom of the rectangular column is fixedly connected to a support foot. A restoring spring is fixedly connected between the first and second connecting plates, and the restoring spring is located outside the damper.

[0018] The technical effect of adopting the above-mentioned further solution is that the damper and the restoring spring can effectively absorb the force brought by the connecting block, thereby achieving buffering of the support foot.

[0019] Preferably, a telescopic rod is fixedly connected to the bottom of the connecting column, and the bottom of the telescopic rod is fixedly connected to the support foot.

[0020] The technical effect of adopting the above-mentioned further solution is that the telescopic rod can restrict the position of the support foot, making the support foot more stable when moving.

[0023] 1.

[0024] 2. This utility model, by setting up connecting pull members and reinforcing pull members, allows the rotor connecting member to withstand large external loads, including tensile and compressive forces, by mainly bearing axial forces, thus preventing aircraft crashes.

Detailed Implementation

[0031] This application provides a truss-type drone frame. By incorporating a buffer assembly, the frame, in conjunction with the connecting column, pivot, connecting plate, first connecting disc, damper, restoring spring, second connecting disc, connecting block, rectangular column, and telescopic rod, provides a buffering effect on the support feet during drone descent, preventing damage from collisions with the ground. The connecting tie mainly bears axial forces, including tension and compression, enabling the rotor connector to withstand larger external loads and preventing crashes. The reinforced tie provides stability and support to the connecting tie, improving its stability during use.

[0032] Example 1

[0033] The technical solutions in this application do not effectively solve the following problems: When existing drones are in use, imbalances caused by changes in rotor lift result in very large torsional forces on the arms. If the fuselage strength is insufficient, or the connection strength between the fuselage and the arms is insufficient, the drone will twist and deform, seriously affecting flight attitude and flight control, and even causing a crash. In addition, existing drones suffer damage to the fuselage upon landing due to ineffective bottom cushioning components, failing to effectively protect the fuselage. The overall approach is as follows:

[0034] like Figures 1 to 4 To address the problems existing in the prior art, this utility model provides a truss-type drone frame, including a drone body 1. Two sets of buffer components 4 are provided at the bottom of the drone body 1. Support feet 5 are fixedly connected to the bottom of each buffer component 4. Multiple connecting rods 11 are fixedly connected to the outside of the drone body 1. One end of the multiple connecting rods 11 is movably connected to a rotor connector 12. Connecting pullers 2 are fixedly connected between the rotor connectors 12. Reinforcing pullers 3 are fixedly connected between the connecting pullers 2 and the connecting rods 11.

[0035] By adopting the above technical solution, these connecting members 2 mainly bear axial force, including tension and pressure, during use, enabling the rotor connecting member 12 to withstand larger external loads. At the same time, the reinforcing member 3 can play a role in stabilizing and supporting the connecting member 2, improving the stability of the connecting member 2 during use.

[0036] Specifically, the shape formed by the connecting tie 2, the connecting rod 11 and the reinforcing tie 3 is a triangle, and the connecting tie 2 and the reinforcing tie 3 are made of carbon fiber material.

[0037] By adopting the above technical solution, the triangular structure makes the reinforcing tie 3, the connecting tie 2 and the rotor connecting 12 more stable, and the carbon fiber material has the advantages of light weight and high strength.

[0038] In this embodiment, the connecting member 2 mainly bears the axial force, including tension and compression, so that the rotor connector 12 can withstand a large external load. At the same time, the reinforcing member 3 can stabilize and support the connecting member 2, improving the stability of the connecting member 2 during use. The triangular structure makes the reinforcing member 3, the connecting member 2 and the rotor connector 12 more stable. Carbon fiber material has the advantages of light weight and high strength.

[0039] Example 2

[0040] like Figures 1 to 4 The buffer assembly 4 includes four connecting columns 41 located at the bottom of the UAV body 1. A rotating shaft 42 is rotatably connected to the opposite side of each connecting column 41. A connecting plate 43 is fixedly connected to the outside of the rotating shaft 42. A first connecting plate 44 is fixedly connected to one side of the connecting plate 43. A damper 45 is fixedly installed on one side of the first connecting plate 44. A second connecting plate 47 is fixedly connected to one end of the damper 45. A connecting block 48 is fixedly connected to one side of the second connecting plate 47. A rectangular column 49 is rotatably connected to one side of the connecting block 48. The bottom of the rectangular column 49 is fixedly connected to the support foot 5. A restoring spring 46 is fixedly connected between the first connecting plate 44 and the second connecting plate 47, and the restoring spring 46 is located outside the damper 45.

[0041] By adopting the above technical solution, the buffer component 4 can be used for buffering when the UAV body 1 lands again. Specifically, when the UAV body 1 lands, the support foot 5 will collide with the ground and generate a force. This force will push the rectangular column 49 to slide. While sliding, the rectangular column 49 will exert a force on the connecting block 48. The damper 45 and the restoring spring 46 can effectively absorb the force brought by the connecting block 48, thereby achieving buffering of the support foot 5.

[0042] Specifically, a telescopic rod 40 is fixedly connected to the bottom of the connecting column 41, and the bottom of the telescopic rod 40 is fixedly connected to the support foot 5.

[0043] By adopting the above technical solution, the telescopic rod 40 can restrict the position of the support foot 5, making the support foot 5 more stable when moving.

[0044] Working principle: During use, the connecting tie 2 mainly bears the axial force, including tension and compression, enabling the rotor connector 12 to withstand a large external load. At the same time, the reinforcing tie 3 can stabilize and support the connecting tie 2, improving the stability of the connecting tie 2 during use. The triangular structure makes the reinforcing tie 3, the connecting tie 2, and the rotor connector 12 more stable. Carbon fiber material has the advantages of light weight and high strength. The buffer component 4 can be used for buffering when the UAV body 1 lands. Specifically, when the UAV body 1 lands, the support foot 5 will collide with the ground and generate a force. This force will push the rectangular column 49 to slide. While sliding, the rectangular column 49 will exert a force on the connecting block 48. The damper 45 and the restoring spring 46 can effectively absorb the force brought by the connecting block 48, thereby achieving buffering of the support foot 5. At the same time, the telescopic rod 40 can restrict the position of the support foot 5, making the support foot 5 more stable when moving.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
