Description
Technical field
This utility model relates to a kind of passenger vehicle high intensity rear wall frame, belongs to automobile manufacturing field.
Background technology
Taking more than 9 people (including operating seat), typically have square compartment, for carrying passenger and the commercial car of 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 use Diesel Driven, currently also have pure electric vehicle, all-metal body.According to the energy consumed in number of passengers calculating and shared path area, 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.For world wide, car manufacturing and universal ratio are wide, therefore as the Coach Manufacture of public transport main body, either 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 rear frame of passenger vehicle is positioned at the tail end of passenger vehicle, and when passenger vehicle generation rear-end impact, it bears main shock pressure, if intensity is the highest, then passenger on car is caused bigger injury.
Utility model content
The deficiency existed for prior art, technical problem to be solved in the utility model is to provide a kind of passenger vehicle high intensity rear wall frame, 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 high intensity rear wall frame, including upper end skeleton, middle part skeleton, front end indulges skeleton and skeleton is indulged in rear end；Described upper end skeleton includes that stay tube is propped up in two upper ends, and it is bending-like that the two ends of stay tube are propped up in upper end, and the plane that stay tube place is propped up in two upper ends is vertically arranged；Described two upper ends are propped up and are provided with 3 bending tubes between stay tube, and bending tube and upper end support sealing of tube and fix；Described middle part skeleton includes two midfoot support pipes, and the two ends of midfoot support pipe are bending-like, and two midfoot support pipe place planes be arranged in parallel；Being provided with 3 connecting tubes between described two midfoot support pipes, connecting tube is fixed with midfoot support sealing of tube；Described front end is indulged skeleton and is included that two are arranged at upper end and prop up the vertical pole between stay tube and midfoot support pipe and two vertical bend pipes being arranged at midfoot support pipe bottom, and two vertical poles be arranged in parallel；Described rear end is indulged skeleton and is included two rear longitudinal tubule (L tubule)s be arrangeding in parallel, and the upper end of rear longitudinal tubule (L tubule) is bending-like and props up with two upper ends that stay tube is fixing to be connected；Fixing with the top of two midfoot support pipes in the middle part of described rear longitudinal tubule (L tubule) and be connected, the lower end of rear longitudinal tubule (L tubule) is connected by two arms and vertical bend pipe are fixing；Parallel between described bending tube being uniformly distributed, the distance between bending tube is that the 2/7 of the length of stay tube is propped up in upper end.
Optimizing, above-mentioned passenger vehicle high intensity rear wall frame, be provided with reinforced pipe between described vertical bend pipe and two midfoot support pipes, reinforced pipe and midfoot support pipe are 45 degree of angles.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Rear wall frame is divided into upper end skeleton, middle part skeleton, front end indulges skeleton and skeleton, ease of assembly are indulged in rear end, it is to avoid the assembling inconvenience that in prior art, whole framework weight is brought more greatly.Upper end skeleton, middle part skeleton, front end indulges skeleton and rear end is indulged skeleton and is simulated by the way of 3D models, define crisscross supporting network, add the skeleton strengths in tension and compression in all angles, in collision experiment, be designed to the mode that arc combines with linear type, and its radian is through calculating the configuration of optimal arc, 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 for upper end prop up stay tube, 2 be bending tube, 3 be midfoot support pipe, 4 be connecting tube, 5 be vertical pole, 6 be vertical bend pipe, 7 be rear longitudinal tubule (L tubule), 8 be reinforced pipe.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of passenger vehicle high intensity rear wall frame, and including upper end skeleton, middle part skeleton, front end indulges skeleton and skeleton is indulged in rear end；Described upper end skeleton includes that stay tube is propped up in two upper ends, and it is bending-like that the two ends of stay tube are propped up in upper end, and the plane that stay tube place is propped up in two upper ends is vertically arranged；Described two upper ends are propped up and are provided with 3 bending tubes between stay tube, and bending tube and upper end support sealing of tube and fix；Described middle part skeleton includes two midfoot support pipes, and the two ends of midfoot support pipe are bending-like, and two midfoot support pipe place planes be arranged in parallel；Being provided with 3 connecting tubes between described two midfoot support pipes, connecting tube is fixed with midfoot support sealing of tube；Described front end is indulged skeleton and is included that two are arranged at upper end and prop up the vertical pole between stay tube and midfoot support pipe and two vertical bend pipes being arranged at midfoot support pipe bottom, and two vertical poles be arranged in parallel；Described rear end is indulged skeleton and is included two rear longitudinal tubule (L tubule)s be arrangeding in parallel, and the upper end of rear longitudinal tubule (L tubule) is bending-like and props up with two upper ends that stay tube is fixing to be connected；Fixing with the top of two midfoot support pipes in the middle part of described rear longitudinal tubule (L tubule) and be connected, the lower end of rear longitudinal tubule (L tubule) is connected by two arms and vertical bend pipe are fixing；Parallel between described bending tube being uniformly distributed, the distance between bending tube is that the 2/7 of the length of stay tube is propped up in upper end.Being provided with reinforced pipe between described vertical bend pipe and two midfoot support pipes, reinforced pipe and midfoot support pipe are 45 degree of angles.
