Problems solved by technology
This structure can effectively prevent external impact and protect the safety of the occupants in the vehicle. However, due to the large amount of plate materials used in this structure, the mass of the vehicle body is large, which leads to a high center of mass of the vehicle and a large fuel consumption of the vehicle. , the second will affect the driving stability of the vehicle

The invention discloses a vehicle body based on the truss skeleton thin shell structure of a composite load bearing type base board. The vehicle body comprises a load bearing type base board, wherein the load bearing type base board is connected with a skeleton formed by a truss structure, a vehicle body shell is connected with the skeleton, the load bearing type base board comprises a non-load bearing type floor board and a split type vehicle frame connected with the floor board, the floor board comprises a front floor board and a back floor board connected with the front floor board, and the front floor board is connected with a left-right floor board; a vehicle frame installing groove is arranged between the front floor board and the left-right floor board, the vehicle frame installinggroove is internally connected with the split type vehicle frame, and the split type vehicle frame comprises a front vehicle frame and a back vehicle frame which are not connected with each other; and a board piece splicing place of the vehicle body shell is arranged at a skeleton girder which forms the truss structure. The vehicle body is low in barycenter, light in weight, and good in protection property.
Description
technical field [0001] The invention belongs to an automobile body, and in particular relates to a vehicle body structure of a truss bearing composite thin shell structure based on a non-bearing floor. Background technique [0002] At present, protective vehicles at home and abroad all adopt non-load-bearing body structure, and the bottom plate adopts non-load-bearing bottom plate structure. After the chassis structure of the vehicle is arranged, the bottom plate of this structure makes the center of mass of the vehicle high, especially after the vehicle is equipped with equipment, making the The center of mass of the vehicle is further increased, which affects the driving stability of the vehicle; at the same time, because the non-load-bearing vehicle body adopts an integral frame structure, the height of the vehicle is high and the mass is large, so it does not use transportation. The body shells are all welded and assembled from plates. The anti-impact method of the body...
