Abstract
The invention discloses a new energy electric automobile body beam frame, which designs a beam frame structure of a bearing type automobile body into a whole, wherein the beam frame consists of three parts, namely an automobile body front longitudinal beam structure, a front floor beam frame structure and a rear floor beam frame structure.
Description
Technical field
The present invention directly applies to field of automobile body design, especially new-energy automobile body drawing, is specifically related to a kind of New-energy electric vehicle vehicle body roof beam structure.
Background technology
Existing motorcar body mainly self-supporting body, beam frame structure incorporates in the structure of vehicle body, because the propulsion source-battery system of New-energy electric vehicle is arranged on vehicle body, and majority of case is under power brick is arranged in body platform, so large weight hanging is on vehicle body, high to the requirement of strength of vehicle body, what existing self-supporting body design mainly carried is the weight of lifting on vehicle body, and the ability of hanging battery is extremely weak, because power brick exists risk in vehicle collisions, the protection power brick needed is not damaged by collision, the method of designing of the overall roof beam structure of vehicle body of the present invention can effectively solve this problem.
Summary of the invention
For deficiency of the prior art, the object of the present invention is to provide a kind of New-energy electric vehicle vehicle body roof beam structure, protection power brick is not damaged by collision, and is arranged on to solve power brick requirement of strength vehicle body met simultaneously under various working condition.
To achieve these goals, the technical scheme that the present invention takes is:
The beam frame structure of self-supporting body is designed to as a whole, is made up of front stringpiece of vehicle body structure, front floor bearer shelf structure, rear floor bearer shelf structure three part, because self-supporting body roof beam structure and vehicle body merge, three
The emphasis of the design when the transition of part roof beam structure effectively connects, by the design of three-dimensional joint, front rail structure is effectively connected with front floor bearer shelf structure, calculated by cae analysis, the structure optimizing three-dimensional joint makes its power transmission smooth and easy, realize front rail structure and front floor bearer to put up and be integrated stressed roof beam structure, simultaneously by bridge transition mode, front floor bearer shelf structure is effectively connected with rear floor bearer shelf structure, optimizes bridge structure and forward and backward beam frame structure one-tenth is integrated jointly bear vehicle body stressed.Such design can make power brick hang on unit body beam frame structure; reach vehicle body roof beam structure effective dispersed cell bag hanging pulling force; solve the problem that body platform cannot bear power brick hanging pulling force, no matter be simultaneously central collision, side impact and after the situation such as to touch and well can protect the not oppressed damage of power brick.
Beneficial effect
The main advantage of the present invention is the method for designing by changing self-supporting body; self-supporting body is made effectively to bear the function of New-energy electric vehicle vehicle body hanging power brick; and provide enough protection intensity to power brick; and by this method of designing; side impact sill strip intrusion volume can reduce 200mm, power brick is reduced 50mm by amount of compression.

Detailed description of the invention
Embodiment 1
In order to overcome the defect that above-mentioned prior art exists, the present invention proposes a kind of New-energy electric vehicle body rail frame method of designing, is arranged on to solve power brick requirement of strength vehicle body met simultaneously under various working condition.
Vehicle Body Design Method of the present invention, the beam frame structure of self-supporting body is designed to as a whole, by front stringpiece of vehicle body structure, front floor bearer shelf structure, rear floor bearer shelf structure three part composition, because self-supporting body roof beam structure and vehicle body merge, the emphasis of the design when the transition of three part roof beams structure effectively connects, by the design of three-dimensional joint, front rail structure is effectively connected with front floor bearer shelf structure, by CAE system analysis computation, the structure optimizing three-dimensional joint makes its power transmission smooth and easy, realize front rail structure and front floor bearer to put up and be integrated stressed roof beam structure, simultaneously by bridge transition mode, front floor bearer shelf structure is effectively connected with rear floor bearer shelf structure, before optimization bridge structure makes, rear beam frame structure becomes one, and jointly to bear vehicle body stressed.Such design can make power brick hang on unit body beam frame structure; reach vehicle body roof beam structure effective dispersed cell bag hanging pulling force; solve the problem that body platform cannot bear power brick hanging pulling force, no matter be simultaneously central collision, side impact and after the situation such as to touch and well can protect the not oppressed damage of power brick.
The main advantage of the present invention is the method for designing by changing self-supporting body; self-supporting body is made effectively to bear the function of New-energy electric vehicle vehicle body hanging power brick; and provide enough protection intensity to power brick; and by this method of designing, the performance such as bus body strength, rigidity can be made to increase.
Last it is noted that obviously, above-described embodiment is only for the application's example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among the protection domain of the application's type.
