Description
Technical field
This utility model belongs to body of a motor car framework technology field, is specifically related to a kind of thermoforming car body frame structure.
Background technology
In recent years, in response to the policy of country, country and automobile factory were all at Devoting Major Efforts To Developing new-energy automobile.Body of a motor car accounts for the 30% of automobile gross mass, and under no-load condition, the electric quantity consumption of about 70% is on body quality.For electric automobile, on the basis of original electricity, for how increasing the course continuation mileage of electric automobile, one of them important solution is exactly body lightening design.Vehicle body is carried out lightweight and can not only reduce the consumption for the energy and the pollution of environment, moreover it is possible to significantly improve the course continuation mileage of pure electric automobile, pure electric automobile is carried out body lightening design and is just particularly important.
Under Vehicle mass reduction main trend, improving bus body strength and be always the problem of vehicle body research and development while how alleviating tare, the collision safety performance of electric automobile receives extensive concern.The bus body strength collision performance of automobile is most important, and body in white is the skeleton of whole automobile, and complete automobile collision contribution rate is more than 60%, so the intensity improving body in white has important effect to collision security performance.
The method improving bus body strength mainly increases the thickness of sheet metal component and replaces two kinds of methods of high intensity Metal plate, but the thickness improving Metal Sheets for Body-manufacturing can increase complete vehicle weight, affect fuel utilization ratio or the energy content of battery, thickness increase simultaneously directly affects feasibility of welds, and effect is not clearly.To being also intended to replace high-strength plate from the point of view of high-end car to increase car body strength, but this kind of method reduces waste, needs research staff to want System Thinking, designs a kind of organization plan and most integral strength is significantly increased.
It is weak which position intensity current solution car body intensity scheme is mainly, just switch to thermoforming sheet material in this region and meet car body performance to increase local strength, but thermoforming is big due to intensity, so forming ability is poor, without planning use these materials cause late stage process to realize difficulty big, debugging cycle is long, is the most sometimes limited by manufacture and cannot directly switch high-strength material to make up intensity.In addition the use thermoforming that the later stage is the most unordered increases intensity and significantly causes the waste of resource, and cost is increased, although supplements local strength, but does not but have the intensity of the whole vehicle body of maximum lift, does not has to use maximally effective for thermoforming performance.
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of thermoforming frame structure and vehicle body.Optimum raising integral strength and collision performance is come by design thermoforming frame structure, considering that practical situation and the bus body strength key area of the collision of vehicle body apply thermoforming frame structure to increase bus body strength, the complexity simultaneously realized according to technique carries out rational deployment to thermoforming frame structure.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, it is provided that the thermoforming car body frame structure that a kind of reasonable in design, vehicle body bulk strength are high, anticollision performance is effectively optimized.

Described A column reinforcement plate, B column reinforcement plate, B post upper reinforcing plate, B post lower reinforcing plate and strengthen the cross section of connecting plate all in " U " type or " several " type.
Described A column reinforcement plate, B column reinforcement plate, B post upper reinforcing plate, B post lower reinforcing plate and reinforcement connecting plate are thermoforming plate 22MnB5 punch forming.
Bottom described A column reinforcement plate and offer rivet hole, A column reinforcement plate and B post lower reinforcing plate on B post lower reinforcing plate and mate stake-fastening with threshold longeron.
The thickness of described A column reinforcement plate, B post upper reinforcing plate and reinforcement connecting plate is 1mm；The thickness of described B column reinforcement plate and B post lower reinforcing plate is 1.5mm.
It is equipped with upper-lower door hinge mounting hole on described A column reinforcement plate and B column reinforcement plate；It is additionally provided with lock pin installing hole and lightening hole on described B column reinforcement plate；Described B post upper reinforcing plate is provided with painting electrophoresis liquid-leaking nozzle.
Use technique scheme, acquired provide the benefit that:
This utility model reasonable in design, by carrying out integrally-built improvement to the gusset weak link of whole vehicle body so that whole car body frame structure, in the case of guaranteeing active strength, reduces the weight of whole framework；This utility model entirety uses U-shaped or a few font, has been greatly reinforced the anticollision performance of body side wall, effectively prevents the amount of invading in side impact, when there is central collision, it is also possible to when impact force is delivered to gusset, and the most flexible flattening of gusset；This utility model is in order to carry out respective outer side edges with the threshold longeron of aluminum alloy material, thus overall body shell is designed to half hollow structure, it is achieved the stake-fastening of the structure of two kinds of unlike materials.
