Description

Landing gear placing cabin Technical Field The utility model belongs to the technical field of unmanned aerial vehicles, and particularly relates to a landing gear placement cabin. Background In the design of the fixed wing unmanned aerial vehicle, the cabin for placing the cabin door which can be opened and closed is configured for the landing gear, so that the aerodynamic resistance in the flight process can be effectively reduced, the energy consumption of a power system is reduced, and the design is very important for improving the flight speed and the cruising ability of the unmanned aerial vehicle. At present, the conventional cabin door opening and closing scheme of a manned aircraft or a large unmanned aircraft generally depends on a driving mechanism with complex structure and large weight to realize reliable opening and closing of the cabin door, and the design emphasis is often on meeting the high load or redundant safety requirements, so that the overall structure is heavy. Although the method has feasibility on a large-scale platform, when the method is applied to a small-scale fixed wing unmanned aerial vehicle, the weight of the whole machine is obviously increased, so that the key performance indexes such as endurance, bearing capacity and the like of the small-scale unmanned aerial vehicle are greatly weakened against the design principles of light weight, simplicity and reliability of the small-scale unmanned aerial vehicle. Disclosure of utility model The utility model aims to provide a landing gear placing cabin, which solves the technical problems of complex structure and large weight of a cabin door opening and closing scheme in the prior art. The utility model discloses a landing gear placement cabin, comprising: The cabin body is internally provided with a storage cavity, and the bottom of the cabin body is provided with an inlet and an outlet; The cabin door is rotationally connected to one side of the bottom of the cabin body and used for opening and closing the inlet and the outlet through overturning; The top end of the landing gear penetrates through the inlet and outlet and is rotationally connected in the Chu Naqiang; One end of the switching rod is rotatably connected to the inner side wall of Chu Naqiang; the transverse pushing rod is arranged at the other end of the switching rod; One end of the push-pull rod is in universal joint with the transfer rod, and the other end of the push-pull rod is in universal joint with the cabin door; One end of the elastic piece is connected with the switching rod, and the other end of the elastic piece is connected with the cabin body; the landing gear can be rotated upwards to be stored in the Chu Naqiang, and the transverse pushing rod can be pushed in the process of rotating upwards to be stored, so that the transfer rod is driven to rotate. The landing gear storage and cabin door opening and closing linkage is realized, so that the landing gear storage and cabin door opening and closing linkage mechanism has the advantages of simple structure, light weight and high reliability on the premise of ensuring functions, realizes overall light weight, reduces operation steps and additional driving mechanisms, improves structural integration level and control portability, is easy to process and manufacture, and reduces the difficulty of production and maintenance. Based on the technical scheme, the scheme of the application can be improved as follows: preferably, it comprises: The limiting block is arranged on the inner side wall of the Chu Naqiang and used for limiting the rotation angle of the adapter rod, by adopting the scheme, the cabin door is stably kept in an open state, the cabin door is prevented from shaking or shifting due to small external force in the open state, and the reliability and the safety of the system are enhanced. Preferably, it comprises: by adopting the scheme, the friction force is greatly reduced, the abrasion of parts is reduced, the service life of the parts is prolonged, and the movement smoothness is improved. Preferably, it comprises: The cabin door is provided with reliable support, can be stably arranged on the cabin body, plays a role in guiding and limiting the overturning of the cabin door, enhances the connection strength between the cabin door and the cabin body, and ensures the structural stability of the whole landing gear placing cabin. Preferably, the connector comprises: the support rod is arranged at the bottom of the cabin body; The overturning plate is arranged on the surface of the cabin door and is in pivot connection with the bottom end of the supporting rod, by adopting the scheme, the cabin door can realize overturning movement relative to the cabin body, stable support and guide are provided for the cabin door, the cabin door can not shake or deviate in the movement process, the structural stability is enhanced, and the fault risk caused by unstable movement of the cabin door is reduced.
