Description
Technical field
The utility model belongs to electric vehicle structure technical field; Relate to a kind of electric car body collision energy-absorbing structure specifically.
Background technology
Along with the development of auto trade, the safety performance of automobile more and more receives everybody concern, also be the index of a measurement car Combination property, for passive security, size and the direction of the crumple distortion of vehicle body are the key factors affecting passenger safety, in auto against, importantly protect the safety of occupant, so the distortion of driving room is in an impact less better, automobile considers this point when designing, when auto against, allow the first crumple of a part of mechanism, absorb the Impact energy of a part, thus reduce the impact being delivered to and driving room, therefore the structure design of car load vehicle body is most important, especially even more important to electric car body, not only replace conventional iron material part with aluminum alloy, also must ensure bus body strength problem with new construction, as the framing member that vehicle offset collision is the most key, the intensity of front side member, particularly the intensity of front side member back segment sinker area is most important for vehicle offset capability, for 40% offset collision, because vehicle only participates in collision less than the structure of half, car body is relatively soft, car body is out of shape seriously in an impact, larger car body intrusion volume can cause passenger's living space not enough, particularly vehicle dash panel plate intrusion volume is larger, shank is caused to injure larger, so design that the high novel electric automobile collision endergonic structure of a kind of structural safety performance just seems very important.
Summary of the invention
Goal of the invention of the present utility model:
Mainly in order to design a kind of novel electric car body collision energy-absorbing structure; the life security of actv. protection chaufeur; under the prerequisite of structural strength ensureing electronlmobil itself, absorb the routed energy colliding and produce to greatest extent, reduce the Impact energy being delivered to and driving room.
The technical solution of the utility model is:
Provide a kind of electric car body collision energy-absorbing structure, comprise front side member assembly, wheel cover is provided with at the two ends, side of front side member assembly, at the sill strip that the rearward end of front side member assembly is respectively arranged with front apron and is connected with front side member assembly, front wall cross sill is also provided with between sill strip, also side wall assembly is provided with in the rear upper end of front side member assembly, top between side wall assembly is also provided with roof drip assembly, the front apron brace panel of car load width is also provided with at the rear upper of front side member assembly, brace panel on the left of front wall is provided with on the left of front apron brace panel, it is bolted to connection.
Described front side member assembly is aluminum alloy material integral casting forming.
Described front side member back segment arranges the horn opening mode that rearward end cross-sectional area is greater than leading section.
Described front apron brace panel is moulded in "Ji" type structure.
On the left of described front wall, the cross sectional shape of brace panel adopts "Ji" type structure.
The beneficial effects of the utility model are:
This battery-driven car body structure design safety is reasonable, absorbs the routed energy colliding and produce to greatest extent, greatly reduces the Impact energy being delivered to and driving room, under the prerequisite of structural strength ensureing electronlmobil itself, and the life security of actv. protection chaufeur.
