Abstract
The utility model discloses the connection structure of a kind of vehicle body and suspension, comprise outside plate and interior brace panel; Described interior brace panel and outside plate form a cavity body structure in this junction.Improve by this cavity body structure the support strength that suspension is connected with vehicle body greatly, complete automobile collision bang path is complete, improves the safety performance of vehicle collision.
Description
Technical field
The utility model relates to a kind of automotive body structure, particularly relates to the structure of a kind of small passenger car vehicle body and suspension junction.
Background technology
In prior art, the structure of suspension and vehicle body junction, for veneer adds the structure of interior brace panel, and the structure of interior brace panel and the structure of outside plate consistent, become fit-state.As the publication number Chinese invention patent application that is CN2841459Y discloses the connection structure between a kind of automotive suspension and vehicle body, this connection structure comprises automotive suspension and vehicle body, and comprising the reinforcement be arranged on vehicle body, automotive suspension is connected on vehicle body by this reinforcement.There are the following problems for this kind of structure: one is the intensity that inner panel is combined with outside plate, and the thickness being equivalent to outside plate increases, and intensity improves little, and when bending distortion occurs outside plate, inner panel is also out of shape thereupon; Two is that inner and outer plates deforms simultaneously, and cause energy transferring path herein to be destroyed, collision energy can not be delivered to body tail, adds the distortion of bottom, floor; Three is structures that outside plate adds inner panel, and the material of product is high tensile steel plate, and thickness is 1.8mm, because high tensile steel plate self-formed shaping easily rebounds, there is bounce-back in product, easily occurs that product laminating is not in place during welding, gap is large, poor welding quality, impact structural strength herein; Four is existing suspensions and the welding of vehicle body inner and outer plates structure, and adopts spot welding weld with protection the connection jointly completed herein, the operation of protection weldering need online under complete, add the operating time under manufacturing line, productive temp increases, production efficiency reduction.
Utility model content
The technical problems to be solved in the utility model is to provide the connection structure of a kind of vehicle body and suspension, improve not quite for existing vehicle body and suspension connecting structure intensity, the product laminating problem causing poor welding quality not in place, it is by improving the connection structure of this suspension and vehicle body, interior brace panel and outside plate is made to form the structure of cavity, improve the intensity that suspension is connected with vehicle body greatly, complete automobile collision bang path is complete, and safety performance promotes.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the connection structure of a kind of vehicle body and suspension, comprises outside plate and interior brace panel; Described interior brace panel and outside plate form a cavity body structure in this junction.Improve by this cavity body structure the support strength that suspension is connected with vehicle body greatly, complete automobile collision bang path is complete, improves the safety performance of vehicle collision.
In order to improve the support strength of this cavity body structure further, described cavity body structure comprises cavity top plate portion and fits with described outside plate and the support plate portion be connected, in step transition between cavity top plate portion and support plate portion.
In order to improve the welding quality of interior strength plates and the Joint strenght with outside plate, described support plate portion is provided with outwards turnover a clinch of fitting with described outer panel structure.
As preferred technical scheme, described clinch is provided with some somes welding holes.Interior brace panel and outside plate adopt spot welding to be connected.
Further, described interior brace panel is an integrally-built sheet metal component.
The utility model structure is simple, and forming process is simple, and this structure welding process is at the scene simple, convenient fixing; Compare original structure, this structure produced on-site technique welding quality promotes, and improves on-the-spot production efficiency, and is welded and fixed conveniently, easy to operate; Form the structure of cavity with outside plate, improve the intensity that suspension is connected with vehicle body greatly, complete automobile collision bang path is complete, and safety performance promotes; The welding manner of interior brace panel and outside plate all adopts point welding process, without the need to operating under manufacturing line, improve the beat of existing production, improve production efficiency.

Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
See Fig. 1, the connection structure of a kind of vehicle body and suspension, comprises outside plate 1 and interior brace panel 2.This interior brace panel 2 forms a cavity body structure with outside plate 1 in this junction.See Fig. 2, this cavity body structure comprises the support plate portion 22 being arranged on interior brace panel 2 upper cavity top plate portion 21 and being bent towards outside plate direction by this cavity top plate portion 21.See Fig. 3 and Fig. 4, between cavity top plate portion 21 and support plate portion 22, be provided with step transition 23.In the present embodiment, this step transition 23 is one-level step.
Outside plate 1, in groove structure, is provided with two sidewalls.The support plate portion 22 of this interior brace panel 2 is provided with the clinch 24 outwards bent by support plate portion 22.This clinch 24 and outside plate 1, in bonding structure, clinch 24 are provided with multiple somes welding holes.This clinch 24 comprises and the laminating of outside plate 1 bottom surface and the laminating with outside plate 1 sidewall with the bonding structure of outside plate 1.Interior brace panel 2 is by being welded to connect on outside plate 1.
Suspension is supported on the cavity top plate portion 21 of this interior brace panel 2 in cavity body structure, and improve the intensity that suspension is connected with vehicle body greatly, complete automobile collision bang path is complete, and safety performance promotes.
Specific embodiment is to more clearly understand the utility model, do not limit as to the one of the utility model right, under the prerequisite not departing from the utility model aim, various change can be had, all these to the apparent amendment of described those skilled in the art by be included in this claim scope within.
