Abstract
The utility model relates to a wind channel fixed beam and use passenger train of this wind channel fixed beam, wind channel fixed beam include main part and overlap part, the wind channel fixed beam is by the panel fashioned piece of bending of bending, the piece of bending has the hem of bending to the main part outward, overlap part by the hem forms, the overlap part sets up on the main part side, the root of overlap part is provided with closing opening. This wind channel fixed beam is through the shaping of bending of a sheet material, has avoided leading to the fact the too big consequence of deflection because stress that the welding results in is too big, has guaranteed its uniformity and precision, and, adopt ordinary girder construction and fixed stay wind channel function integrated roof beam structural cross section, simplified current technology, reduced the influence of human factor to the installation quality.
Description
Technical field
This utility model is related to a kind of car skeleton parts, more particularly to a kind of air channel fixed beam.This utility model is also
It is related to a kind of passenger vehicle including this air channel fixed beam.
Background technology
Air channel fixed beam is the key components and partss of Bus Frame, and its Main Function is that fixing offer for air channel positions and prop up
Support, the manufacturing of therefore air channel fixed beam needs to ensure that it has concordance, and deflection is little, to reach the mesh of stable fixation
's.Traditional technique is formed by a rectangular tube and a l shape pipe welding, and the part that rectangular tube is constituted is main part, l shape
The outstanding edge of pipe is divided into overlap part, in order to install and to fix air channel.Because traditional handicraft is formed for welding, meeting in welding process
Produce larger stress, and affected by anthropic factor during welding, therefore can lead to traditional fixed beam deflection relatively
Greatly, precision and concordance cannot ensure, bring very burden to follow-up air channel fixation.A kind of guarantee installation accuracy is therefore provided
Necessary with conforming air channel fixed beam.
Content of the invention
The purpose of this utility model is to provide a kind of air channel fixed beam so as to ensure that the essence in the fixation procedure of air channel
Degree and concordance.
For achieving the above object, technical solutions of the utility model are:
A kind of air channel fixed beam, including main part and overlap part, described air channel fixed beam is by sheet metal bending molding
Bending part；Bending part has the flanging to bending outside main part, and described overlap part is formed by described flanging.
Described overlap part is arranged on the side of described main part, and the root of described overlap part is provided with closing
Mouthful.
Described air channel fixed beam is integrally formed for roll-in.
Described closing mouth is formed by online welded closed.
Described closing mouth first connecting portion formed by the root of overlap part, second connecting portion by with strip width direction
The overlap joint flanging that the corresponding edges part bending of side is formed is formed.
A kind of passenger vehicle, including air channel fixed beam, described air channel fixed beam includes main part and overlap part, described air channel
Fixed beam is by the bending part of sheet metal bending molding；Bending part has the flanging to bending outside main part, described overlap part
Formed by described flanging.
Described overlap part is arranged on the side of described main part, and the root of described overlap part is provided with closing
Mouthful.
Described air channel fixed beam is integrally formed for roll-in.
Described closing mouth is formed by online welded closed.
Described closing mouth first connecting portion formed by the root of overlap part, second connecting portion by with strip width direction
The overlap joint flanging that the corresponding edges part bending of side is formed is formed.
The beneficial effects of the utility model are: this utility model passes through one piece of plate bending and molding, it is to avoid due to welding
The stress leading to is excessive and causes the excessive consequence of deflection it is ensured that its consistency and precision.And, using common girder construction
With the fixing girder construction section supporting air channel function integrated, simplify existing process, decrease anthropic factor to installation quality
Impact.
Brief description
Fig. 1 is specific embodiment of the utility model structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
Specific embodiment of the utility model, as shown in figure 1, this utility model air channel fixed beam is to be passed through by one piece of plate
The integrally formed bending part of roll-in.Air channel fixed beam is integrally rectangular, and including main part 1 and overlap part 2, bending part has
To the flanging of the outer bending of main part 1, described overlap part 2 is formed by described flanging；Overlap part 2 is arranged on described main part
Divide on 1 side, the root 4 of above-mentioned overlap part 2 is provided with closing mouth 5, and described closing mouth 5 is arranged on integrally formed bending part
At closure, formed by first connecting portion and second connecting portion, wherein, first connecting portion is formed by the root of described overlap part 2,
Second connecting portion is formed by the overlap joint flanging that the corresponding edges of strip width direction side are bent to form, and described overlap joint flanging is
Closure flange 3, is formed with closing mouth 5 between this closure flange 3 and root 4 of overlap part 2, and, this closing mouth 5 passes through to fly
Rim portion 2 is welded to each other with closure flange 3 and is formed.The bending angle θ of the root 3 of overlap part 2 is 90 degree it is ensured that installing
Preferably operate fixing air channel beam in journey, fixing hole 6 is provided with overlap part 2, air channel beam can be conveniently installed.
When using, by air channel fixed beam positioning stablity, fixing hole be aligned needs the screwed hole of installation locking, using screw
Fastening can complete to install.
In other specific embodiments of the present utility model, during the bending place of overlap part may be provided at plate shaping
Other positions, as at the seamed edge of described main part.
In other specific embodiments of the present utility model, the wrap direction of closure flange can be outside, partly puts down with overlap
Row overlap joint.
In other specific embodiments of the present utility model, the closed manners of closing mouth can use rivet using after flange overlap joint
Be connected closure.
In other specific embodiments of the present utility model, air channel fixed beam can adopt other bending integral forming process
Produce, be such as integrally formed using bender.
The above embodiment is only that preferred implementation of the present utility model is described, not new to this practicality
The scope of type is defined, and on the premise of without departing from this utility model design spirit, those skilled in the art are new to this practicality
Impartial deformation and improvement that the technical scheme of type is made, all should fall into the protection model that claims of the present utility model determine
