Description
Technical field
This utility model relates to a kind of passenger vehicle afterbody crash-proof bracket, belongs to automobile manufacturing field.
Background technology
Taking more than 9 people (including operating seat), generally have square compartment, for the commercial car of carrying passenger and personal luggage thereof, this kind of vehicle is mainly used in public transport and group's transport uses.Passenger vehicle has monolayer, also has bilayer；Have hinged, also have drawbar trailer type.There are two, single-door, or have luggage compartment.Most passenger vehicles adopt Diesel Driven, currently also have pure electric vehicle, all-metal body.Calculate the consumed energy and shared path area according to number of passengers, mass transportation facilities is than individual vehicle economy, and this is the one of the main reasons that many countries first develop public transport passenger vehicle.Saying from world wide, car manufacturing and universal ratio are wide, therefore as the Coach Manufacture of public transport main body, no matter are from design concept or designing technique, all show quite ripe, and Bus Technology level and the capacity of scientific research in Europe occupy first place in the world.The designed capacity of Chinese Bus Industry and manufacture level, occupy important position in the world.The afterbody crash-proof bracket of passenger vehicle is positioned at the rear end of passenger vehicle, and when there is rear-end collision, it is stress bear maximum pressure at first, and existing afterbody crash-proof bracket beam strength is not high, and when passenger vehicle collides, its framework is yielding causes danger.
Utility model content
For the deficiency that prior art exists, technical problem to be solved in the utility model is to provide a kind of passenger vehicle afterbody crash-proof bracket, and support safety is reliable, and intensity is high.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of passenger vehicle afterbody crash-proof bracket, including two upper support bars be arrangeding in parallel, lower support bar, two outer support bars be arrangeding in parallel and two inner bracing pieces；Described inner bracing piece is arranged between upper support bar and lower support bar, and the angle of inner bracing piece and upper support bar is 79 degree, is provided with reinforcement support bar between inner bracing piece and lower support bar, and the angle strengthening support bar and inner bracing piece is 36 degree；Described lower support bar is fixing with the end of upper support bar is connected outer support bar, and the two ends of lower support bar are respectively arranged with the obtuse angle bending of 127 degree；The lower bracing piece of L-type it is provided with between bending part bottom, obtuse angle and the outer support bar of described lower support bar；Described upper support bar is included in the middle part of upper support rod rear end, upper support bar by center line to end and upper support bar front end；Described upper support bar front end differs 89mm every its horizontal range of 100mm in their extension direction, and the vertical height of continuity is 200mm；Differing 3mm every its horizontal range of 100mm in their extension direction in the middle part of described upper support bar, the vertical height of continuity is 500mm；Differing 2mm every its horizontal range of 100mm in their extension direction in the middle part of described upper support bar, the vertical height of continuity is 500mm.
Optimizing, above-mentioned passenger vehicle afterbody crash-proof bracket, described be provided with bending bracing piece between adjacent outer support bar and inner bracing piece, the bending angle of bending bracing piece is 89 degree.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Rear anti-crash is supported beam it is divided into upper support bar, lower support bar, outer support bar and inner bracing piece, ease of assembly, it is to avoid the assembling inconvenience that in prior art, whole framework weight is brought more greatly.Upper support bar, lower support bar, outer support bar and inner bracing piece are by increasing bending bracing piece, lower bracing piece and strengthening support bar, and the mode modeled by 3D is simulated, define crisscross supporting network, add the skeleton strengths in tension and compression in all angles, in collision experiment, it is designed to the mode that arc combines with linear type, and its radian is through calculating best arc configuration, enhance the bulk strength of a support component, in an impact, reduce deformation, improve intensity, add the safety of passenger vehicle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1 be upper support bar, 2 be lower support bar, 3 be outer support bar, 4 be inner bracing piece, 5 for strengthening support bar, 6 be lower bracing piece, 7 for bending bracing piece.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with accompanying drawing and specific embodiment.
This utility model is a kind of passenger vehicle afterbody crash-proof bracket, including two upper support bars be arrangeding in parallel, lower support bar, two outer support bars be arrangeding in parallel and two inner bracing pieces；Described inner bracing piece is arranged between upper support bar and lower support bar, and the angle of inner bracing piece and upper support bar is 79 degree, is provided with reinforcement support bar between inner bracing piece and lower support bar, and the angle strengthening support bar and inner bracing piece is 36 degree；Described lower support bar is fixing with the end of upper support bar is connected outer support bar, and the two ends of lower support bar are respectively arranged with the obtuse angle bending of 127 degree；The lower bracing piece of L-type it is provided with between bending part bottom, obtuse angle and the outer support bar of described lower support bar；Described upper support bar is included in the middle part of upper support rod rear end, upper support bar by center line to end and upper support bar front end；Described upper support bar front end differs 89mm every its horizontal range of 100mm in their extension direction, and the vertical height of continuity is 200mm；Differing 3mm every its horizontal range of 100mm in their extension direction in the middle part of described upper support bar, the vertical height of continuity is 500mm；Differing 2mm every its horizontal range of 100mm in their extension direction in the middle part of described upper support bar, the vertical height of continuity is 500mm.Described being provided with bending bracing piece between adjacent outer support bar and inner bracing piece, the bending angle of bending bracing piece is 89 degree.
