Abstract
The utility model provides an integral U-shaped beam structure for a bus body, comprising an outer frame structure, an inner frame structure is arranged in the outer frame structure, and a roof outer trimming, side window glass, a roller covering skin and a storage room door are arranged outside the outer frame structure; the integral U-shaped beam structure for the bus body is characterized in that the outer frame structure is provided with more than two integral U-shaped beams with downward openings, and a longitudinal beam, two ends of which are fixedly arranged on the adjacent beams respectively so as to connect the U-shaped beams and form the outer frame structure, wherein the U-shaped beams are arrayed longitudinally. In the design scheme of the utility model, in the light of a keel structure, a plurality of independent U-shaped beams are connected into a closed integral outer frame by the longitudinal beam in longitudinal direction; the technical characteristics are as follows: when the bus body is impacted by lateral side force, the main force bearing points are positioned on the junction positions of the upper edge and the lower edge of the side window glass along a skeleton, the integral U-shaped beam at the position is integral square steel, material change caused by welding does not exist, the deformation is little, and fracture can not happen, so that the safety of passengers is ensured.
Description
Affiliated technical field
The utility model relates to a kind of structure of bus body, the integrally-built improvement of particularly a kind of bus body.
Background technology
Domestic bus body general frame structure all is to adopt six sheets (both frame assembly was enclosed in front wall frame assembly, rear wall frame assembly, roof skeleton assembly, left side, frame assembly, floor frame assembly are enclosed in the right side) to weld the outside frame structure that forms as shown in Figure 3 at present, be provided with bearing wall and frame structure 10 in the outside frame structure, the outside frame structure is provided with outer attachment (not shown) such as the outer mask of roof, side window glass, roll-in covering, luggage door outward.
As shown in Figure 3, because this kind car body frame structure has the longeron 40 that extends through the tailstock from headstock, so body structure stresses is stressed longitudinally, and when vehicle was subjected to clashing into, its longitudinal stress major part was absorbed by longeron 40 and alleviated vertical body distortion.But this structure on side window pillar 400 stop portion 41, down the connection structure of stop portion 51 is the welding that side window pillar 400 docks with longeron 40, thereby produce unavoidable on the weak sidely, it is relatively poor to cause side direction to resist impulsive force.When vehicle was subjected to clashing into, the stressed centrostigma of body shell exactly was positioned at the intersection of the upper and lower edge of side window glass skeleton, also was the last stop portion 41 of side window pillar 400, following stop portion 51.As shown in Figure 4, under the external force F effect that bump produces, stressed centrostigma is the welded structure that the following stop portion 51 of side window pillar 400 docks with longeron 40 owing to employing side window pillar 400, rupture easily in the commissure, in like manner, another stressed centrostigma is the also fracture easily of last stop portion 41 weld seams of side window pillar 400 among Fig. 3, thereby also makes car load produce bigger distortion, causes passenger's injures and deaths.Injures and deaths statistics to repeatedly passenger vehicle traffic accident shows that most of passenger's injures and deaths all are that the serious side distortion of vehicle body causes, and have become one of top priority of present enhancing bus safety so increase the intensity of vehicle body section.
Summary of the invention
The utility model provides a kind of bus body integral type U type girder construction, and its purpose is to solve in the existing passenger vehicle structure vehicle body side bigger problem of ability that is hit, the car load safety that improves passenger vehicle.
The technical solution adopted in the utility model is:
Bus body integral type U type girder construction, comprise the outside frame structure, be provided with bearing wall and frame structure in the outside frame structure, the outside frame structure is provided with the outer mask of roof, side window glass, roll-in covering, luggage door outward, it is characterized in that: the outside frame structure has the downward opening integral type U type crossbeam more than two, U type crossbeam is vertically arranged, and has two ends and is fixedly arranged on longeron on the adjacent beams respectively with the adjacent U type crossbeam outside frame that is formed by connecting.
The beneficial effects of the utility model are: the utility model design concept is from the shape of bionics keel, its principle is that skeleton integral body can be born vertical, horizontal external force, external force is disperseed, make the distortion of health section keep certain scope forever, thereby guaranteed the safety of internal organ.The utility model design plan is vertically connecting into an osed top outside frame integral body by longeron (respectively is longeron, waist rail and storage room longeron under car body top cover longeron, the side window glass according to different parts) respectively just in view of this keel structure with a plurality of independently " U " type crossbeam beam; Its technical characterstic is when vehicle body is subjected to the side direction external force collision, main stress point is in the intersection of the upper and lower edge of side window glass skeleton, and integral type " U " type beam is whole square steel herein, being welded the material of being brought changes, deflection is minimum, can not produce fracture, thereby guarantee passenger's safety.
Description of drawings
Fig. 1: be structure three-dimensional scheme drawing of the present utility model;
Fig. 2: be " A " local enlarged diagram among Fig. 2;
Fig. 3: be the structure three-dimensional scheme drawing of the conventional vehicle body of prior art;
Fig. 4: be " B " local enlarged diagram among Fig. 4.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, present embodiment outside frame structure has some downward opening integral type U type crossbeams 1 and vertically arranges, U type crossbeam 1 cross section as shown in Figure 1, some two ends are welded in longeron 20 (being respectively longeron under car body top cover longeron, the side window glass, waist rail and storage room longeron according to the position difference) on the adjacent U type crossbeam respectively with the adjacent U type crossbeam outside frame that is formed by connecting.Be provided with bearing wall and frame structure 10 in the outside frame structure, the outside frame structure is provided with the outer mask of roof, side window glass, roll-in covering, luggage door (not shown) outward.
When the external force F that bump produces among Fig. 2 acts on vehicle body side U type crossbeam 1, its stressed centrostigma 31 (also being the intersection of side window glass lower edge skeleton) since U type crossbeam for penetrating stress point, whole stressed, stressed centrostigma 31 places among Fig. 2 are welded the material of being brought and are changed, avoided owing to the rotten fracture that produces of material, it is minimum material deformation, guaranteed the safety of car load, in like manner, stressed centrostigma 21 among Fig. 1 (also being the intersection of side window glass upper edge skeleton) has also been avoided owing to the rotten fracture that produces of material, be minimum material deformation, guaranteed the safety of car load.
The above, only be that this practicality is done any restriction to technical scope of the present utility model, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
