Abstract
The utility model discloses the upper frame bar structure of a kind of automobile front door frame, including upper frame bar body, described upper frame bar body includes cylinder and extension board, described cylinder is by the open column shape structure of sheet material roll-forming, in the middle part of described extension board, bending and bending angle are more than 90 degree, described extension board is positioned at the top of cylinder, and the lower end of extension board is connected with the front side of cylinder, and the upper end of described extension board is horizontally disposed with.Upper frame bar body includes that cylinder and extension board, cylinder open column shape structure improve the structural strength of whole upper frame bar body, and in the middle part of extension board, bending and bending angle are more than 90 degree, and the setting of bending also contributes to improve overall structural strength.The lower end of extension board is connected with the front side of cylinder, and the upper end of extension board is horizontally disposed with.The frontside area of upper frame bar body is relatively big, and after therefore upper frame bar body is installed with opponent's part, sealing is relatively strong, good decorative property.
Description
Technical field
This utility model relates to a kind of auto parts and components, especially relates to the upper frame bar structure of a kind of automobile front door frame.
Background technology
In the past, as car door, it is known to by the door frame constituting window frame being fixed on can opening and closing relative to vehicle body
The car door of door body (door panel) that arranges of mode.Such door frame possesses: be fixed on the upper ledge of door body
Bar, and towards vehicle both sides extend column and connect two heel posts lower end and along two heel posts towards vehicle lower side extend
Main frame.
Automotive door frame structure mainly goes out the folding part of many by roll forming and has the shape of cross section of complexity, and
Sealability and dicoration are played a decisive role by shape of cross section when assembling with other opponent's part, and rise with other assembly coordinates
The section structure relying primarily on doorframe determine, the shortcoming that existing automobile front door frame is primarily present is: overall intensity
More weak, and overall install with opponent's part after sealing poor, affect normally using of front truck doorframe.
Summary of the invention
Technical problem to be solved in the utility model is to provide the upper frame bar structure of a kind of automobile front door frame, has structure
Intensity is high, it is adaptable to install.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: the upper frame bar knot of a kind of automobile front door frame
Structure, including upper frame bar body, described upper frame bar body includes cylinder and extension board, and described cylinder is by sheet material roll-forming
Open column shape structure, in the middle part of described extension board, bending and bending angle are more than 90 degree, and described extension board is positioned at the upper of cylinder
Side, the lower end of extension board is connected with the front side of cylinder, and the upper end of described extension board is horizontally disposed with.
The upper surface of described cylinder is provided with the first groove of sleeve configuration, and the cross section of the first described groove is oval
Shape structure, a sidewall of the first described groove withstands on the inner side of described extension board lower end, and the leading flank of described cylinder sets
Being equipped with the second groove of sleeve configuration, the cross section of the second described groove is inverted U-shape structure and Open Side Down, described
The bottom surface of two grooves is against the bottom surface of the first described groove.Arrange the first groove on cylinder, the second groove can be effectively increased
The structural strength of cylinder.In addition the first groove, the second groove can coordinate opponent's part to install so that easy for installation and sealing
Well.
Described extension board includes upper plate and the lower plate overlapped up and down, and described upper plate is connected with the upper surface of cylinder, institute
The lower plate stated is connected with the front end face of cylinder, there is gap between bottom and the bottom of lower plate of described upper plate.Extend
The lower end of plate is connected with cylinder, and its respective outer side edges cylinder is arranged.
The top of described upper plate bends downwards and constitutes horizontal U-shape structure part, and the top of described lower plate is inserted described
U-shape structure part in, lower plate is fixed by described U-shape structure part.The upper end of extension board is the dual-side of whole sheet material, logical
Cross and be rolled into U-shape structure part and fix connection, not only add the structural strength of extension board upper end, and simplify whole upper ledge
Fixing of bar body.
Compared with prior art, the utility model has the advantage of that upper frame bar body includes cylinder and extension board, cylinder is empty
Heart column structure improves the structural strength of whole upper frame bar body, and in the middle part of extension board, bending and bending angle are more than 90 degree, curved
The setting of folding also contributes to improve overall structural strength.The lower end of extension board is connected with the front side of cylinder, the upper end of extension board
It is horizontally disposed with.The frontside area of upper frame bar body is relatively big, and after therefore upper frame bar body is installed with opponent's part, sealing is relatively strong, decoration
Property is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
