Abstract
The utility model relates to a light school bus with a frame structure. Rectangular square pipes are adopted to form a frame of the whole bus. Six large frame assemblies, including a welded ceiling, a left side enclosure, a right side enclosure, a front enclosure, a rear enclosure and a floor, are positioned and welded together in stereo folded tires to form a frame enclosed ring structure. In the frame enclosed ring structure, ceiling transverse shed bars and side window upper beams in the side enclosure frames are welded together to form an upper framework, side enclosure columns, rear enclosure columns and floor transverse cross arms are welded together, and the floor cross arms are connected with a bus frame via a bracket assembly, such that a one-body enclosed ring frame structure of the whole bus is formed. The beneficial effects of the light school bus with a frame structure are that three-dimensional stereo modeling is employed to form a bus body, rectangular square pipes are adopted to form the frame of the whole bus, and a ceiling frame, side enclosures and a floor frame form an enclosed ring structure on the same cross section, therefore, the strength of the whole bus is ensured and damage coefficients are reduced to the maximum once the bus bumps or overturns.
Description
Technical field
The present invention relates to a kind of light-duty school bus of skeleton structure, especially grow a moulding, the school bus of square tube skeleton, enclosed ring design, belongs to automobile skeleton structure technical field.
Background technology
At present according to statistics, school bus accident 75% is to occur in rural area, and the rural area level of economic development is relatively low, 12 years school bus Frequent Accidents, country, for rectifying school bus market, has promulgated a series of special school bus standards and implementing regulations, the universal common cry of the whole society that become of special school bus.School bus market becomes will have the segmenting market of growth potential most future, and will will be explosive growth at the five-year.
Summary of the invention
The purpose of this utility model is to provide a kind of skeleton enclosed construction of light-duty school bus, to ensure integral strength, reduces to greatest extent injury coefficient in the time bumping, turn on one's side.
The technical scheme that the utility model adopts is: the light-duty school bus of this skeleton structure, car load skeleton adopts rectangle square tube, welding ceiling, left-side, right side wall, front wall, back wall, the large stretch of frame assembly in floor six, close up positioning welding in tire in solid and jointly form skeleton enclosed ring.
The light-duty school bus of described skeleton structure, described enclosed ring is the side window upper cross beam welding in the horizontal canopy bar of ceiling and side wall frame assembly, forms top skeleton; Side wall pillar, back wall pillar and the welding of floor cross-arm, floor cross-arm is connected with vehicle frame by bracket assembly again, and car load has just formed the closed-loop skeleton structure of one like this.
The light-duty school bus of described skeleton structure, described ceiling frame assembly is formed by multiple horizontal canopy bars and the vertical support of ceiling welding.
The light-duty school bus of described skeleton structure, described right side wall frame assembly connects square steel by side wall pillar, side window pillar, back wall pillar, side window entablatrance, side window cross sill, floor and the welding of gusset diagonal ligament forms.
The light-duty school bus of described skeleton structure, described floor frame assembly is formed by the vertical support of multiple floors cross-arm and floor welding.
The light-duty school bus of described skeleton structure, described front wall frame assembly is formed by grit square tube welding under grit, air regulator on sector tube, air regulator.
The light-duty school bus of described skeleton structure, described rear wall frame assembly is formed by back door stile, upper ledge, lower frame and connection support welding.
The beneficial effects of the utility model are: vehicle body adopts 3 D stereo modeling, car load skeleton adopts rectangle square tube, on same cross-sectional plane, ceiling skeleton, gusset, floor frame (except rear tyre arc place) form enclosed ring, ensure like this integral strength, in the time bumping, turn on one's side, reduce to greatest extent injury coefficient.
The assemblies such as front wall assembly, back wall assembly and gusset, ceiling attach together welding at DNA mitochondrial DNA, have ensured welding quality.Skeleton combines with outer covering piece, and vehicle body moulding location is easy, solder joint is few, efficiency is high; The hidden weld seam of car load, has alleviated welding job amount.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated to annexation and technical meaning:
As shown in Figure 1, Figure 2, shown in Fig. 7, compared with the inside and outside panel beating welded structure of the utility model structure and traditional passenger vehicle, the welding manner that adopts square tube to combine with inside and outside panel beating.Car load skeleton adopts rectangle square tubes soldering, closes up welding in tire form by left side, right side, ceiling, front wall, back wall, the large stretch of frame assembly in floor six in solid.The horizontal canopy bar 5 of ceiling welds with the side window entablatrance 8 in side wall frame assembly, side wall pillar 2, back wall pillar 4 etc. weld with floor cross-arm 6, floor cross-arm 6 is connected with vehicle frame by bracket assembly 7 again, car load has just formed the closed-loop skeleton structure of one like this, improve the rigidity of car load, the injury coefficient to passenger while having reduced because of collision, rolling body distortion.
Wherein:
Left and right gusset frame assembly connects square steel 11 by column 2, side window pillar 3, back wall pillar 4, side window entablatrance 8, side window cross sill 9, floor and 10 weldings of gusset diagonal ligament form.
Ceiling frame assembly is formed by multiple horizontal canopy bars 5 and the vertical support of ceiling 12 weldings.
Floor frame assembly is formed by the vertical support of multiple floors cross-arm 6 and floor 17 weldings.
Front wall is formed by square tube weldings such as grits 19 under grit 18, air regulator on sector tube 1, air regulator.
