Description

Technical Field

[0001] The utility model relates to a high-strength manganese steel chassis beam structure of an off-road tourist sightseeing vehicle, and belongs to the field of tourist sightseeing vehicle manufacturing. Background Art

[0002] The sightseeing bus uses batteries to generate power, which is environmentally friendly and pollution-free, and effectively utilizes resources. The sightseeing bus has a personalized control system, flexible steering, comfortable feel, light and smooth, simple driving, electric recyclable, and long life.

[0003] Most chassis connecting beam structures are made of steel because the chassis is subjected to complex forces. It must bear various loads from the road surface and the load inside the vehicle. At the same time, the front suspension assembly, rear suspension assembly, steering assembly, energy assembly and power assembly need to be installed on the chassis structure, so the strength and stiffness of the chassis beam are required to be high. The stability and structural deformation resistance of the high-strength manganese steel chassis of tourist sightseeing vehicles are also of great significance. Therefore, in response to the above problems, a high-strength manganese steel chassis beam structure for off-road tourist sightseeing vehicles is proposed. Utility Model Content

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a high-strength manganese steel chassis beam structure for off-road tourist sightseeing vehicles, including side beam frames, a middle cross beam frame, a middle longitudinal beam frame, an oblique support beam frame, a seat connecting beam and a pillar. The bottoms of both sides of the side beam frames are respectively welded and fixed to each other with a side corresponding to the middle cross beam frame through a group of distributed oblique support beam frames, and pillars are vertically welded on the same group of oblique support beam frames, and the top ends of the pillars of the same group are welded and fixed to each other at corresponding positions of the bottom of the same seat connecting beam.

[0006] Furthermore, the middle position of the middle longitudinal beam frame and the middle position of the middle cross beam frame are welded and fixed to each other.

[0007] Furthermore, the oblique support beam and the corresponding oblique support beam in another group form a triangular support structure.

[0008] Furthermore, the seat connecting beam is provided with a plurality of connecting holes.

[0009] Furthermore, one side edge of the seat connecting beam is welded and fixed to a corresponding portion of the side beam frame.

[0010] Compared with the prior art, the advantages of the utility model are that the side beams, the middle cross beams and the middle longitudinal beams are welded together in grids, and at the same time, multiple groups of oblique support beams are welded to form triangular supports in each grid structure space, forming a stable structure with good strength and not easy to bend and deform.
