Description
Technical field
The utility model relates to a kind of automotive body structure, especially relates to a kind of automobile top-cap crossbeam body contact structure.
Background technology
The safety problem of Passenger motor vehicle more and more receives designer and user's concern; It is particularly important that the complete vehicle structure safety performance seems; China has complete collision Star-Class Assessment System and strong inspection rules; Requirement has the safety of the good body structure of structural strength with the protection occupant, and while structure and the body structure that technology is simple, with low cost, passenger protection is respond well also can improve the competitive position of vehicle.Car roof skeleton and vehicle right and left gusset, front structure, rear structure are fixed together; At vehicle generation side collision or when rolling; An impact force part is delivered to threshold, seat crossbeam through gusset center pillar lower end; A part is delivered to roof rail, roof cross beam through gusset center pillar upper end, and is distributed to whole vehicle body through these framing members, and the car roof skeleton plays and reduces body distortion; Prevent the effect that passenger's living space is invaded, so the crashworthiness of the design of roof skeleton structure must consider that side collision and automobile roll the time; The roof panel cross member of orthodox car is connected with roof rail through connecting panel, and roof rail is connected with gusset center pillar upper end again; Therefore roof cross beam and gusset center pillar are to link together indirectly; There is the structural weak layer in the centre, because roof rail be the cavity structure along the car body fore-and-aft direction, when generation collision is under the impact force effect perpendicular to the roof rail direction again; The easy deformation in compression of roof rail cavity structure; And roof panel cross member can not provide enough intensity supports to this, causes center pillar upper end direction in car to be invaded, and influences occupant's living space.The Chinese patent document discloses the patent of " a kind of crossbeam of automobile top-cap "; Its Granted publication number is CN 201712674 U; Granted publication day is on January 19th, 2011, and this utility model comprises the crossbeam that is arranged on automobile top-cap middle part, and crossbeam is by inner panel and outside plate is affixed forms; Its inside has cavity, can transmit the load in the side collision well." a kind of crossbeam of automobile top-cap " patent of introducing is above strengthened the structure of roof panel cross member; But at automobile generation side collision or when rolling; Impact force is transmitted to roof panel cross member from center pillar and roof rail; What bear impact force earlier is roof panel cross member and the connection structure of the two, just is passed to the roof panel cross member body then, so the connection structure intensity of reinforcement roof panel cross member and center pillar, roof rail also is an aspect of body structure safety assurance.
The utility model content
The utility model is for the intensity problem on the weak side of the automobile top-cap crossbeam body contact structure that overcomes prior art, provides a kind of and improves connecting bridge intensity, and simple automobile top-cap crossbeam body contact structure.
To achieve these goals; The utility model adopts following technical scheme: a kind of automobile top-cap crossbeam body contact structure, comprise roof rail, roof rail brace panel, center pillar top inner panel, center pillar master brace panel, and plate portion is folded mutually in roof rail and the center pillar top; The roof rail brace panel is overlying on outside roof rail and the center pillar top inner panel; Center pillar master brace panel is overlying on outside the inner panel of center pillar top, also comprises roof panel cross member, and described roof panel cross member is an arch; Cross-beam body that is provided with the arch stage casing and the crossbeam pin of under the arch two ends, stretching, described crossbeam pin be located at roof rail and center pillar top inner panel outward, in roof rail brace panel and the center pillar master brace panel.The roof panel cross member of orthodox car; Basically be a writing board shape; With roof rail only be the welding of pressing close on limit and limit; Then below strengthen being connected of roof panel cross member and roof rail through welding a connecting panel, roof rail is connected with gusset center pillar top, roof cross beam and gusset center pillar link together indirectly; For this reason, be designed to arch to roof cross beam now, promptly be provided with respectively to the crossbeam pin that extends below being flat roof cross beam body two ends; The crossbeam pin inserts the roof rail and the center pillar top inner panel outside; Crossbeam pin outside covers roof rail brace panel and center pillar master brace panel again, and like this, roof panel cross member and center pillar have been realized direct connection; And in roof panel cross member was contained in roof rail after extending below, whole connection structure had the bigger ability of resisting side collision force; Roof panel cross member and the connecting panel between the roof rail in the traditional design have been cancelled in the roof panel cross member of arch design, have also practiced thrift cost.
As preferably, described roof panel cross member is provided with the stress buffer section between cross-beam body and crossbeam pin, and described stress buffer section is an arc.When automobile generation side collision; The suffered impact force of roof panel cross member is delivered on the cross-beam body from the crossbeam pin because cross-beam body is identical with the side collision force direction, and between crossbeam pin and cross-beam body angle near the right angle; So big easy deformation of cross-beam body and crossbeam pin place stress; With the stress buffer section that is designed to arc here, dispersive stress reduces distortion preferably.
As preferably, described roof panel cross member stress buffer section is provided with reinforced rib.The stress buffer section is the significant points that the suffered side collision force of roof panel cross member is transmitted and born; If the intensity of stress buffer section itself is low excessively; Can cause the stress buffer section promptly to deform in the cross-beam body in that side collision force is passed to, this obviously is unsafe, so stress buffer section itself also should have higher bend resistance intensity; Reinforced rib is set on the stress buffer section can improves bend resistance intensity preferably, when manufacturing, can accomplish with a punching press of body.
As preferably, described roof panel cross member is an integral structure.Can adopt a high efficiency drawing in process of production for the intensity that improves roof panel cross member itself reaches, roof panel cross member adopts integral structure, reduces production process, and is easy installation and reliable.
Therefore, the utlity model has following beneficial effect: the intensity of automobile top-cap crossbeam body contact structure has been improved in (1); (2) simple in structure, produce easy installation and reliable.
