Description
Technical field
The invention belongs to field of automobile, and knot is connect with sill strip more particularly, to a kind of body platform crossbeam
Structure.
Background technique
Aluminium has the advantages that density is low, light-weight.Consider from lightweight angle, aluminium is a good material, but aluminium sheet
Molding part, die cost is high when manufacture, difficult forming, and intensity, rigidity are not so good as steel part.The part of aluminium profile structure,
Squeezed out when itself there is enough intensity and rigidity, manufacture for cross-section, manufacturing expense is low, therefore aluminium often in a manner of profile
Occur on vehicle body.It is MIG weldering, riveting that common connection type is connected between profile.Part deformation is big when MIG is welded, and precision is difficult to ensure
Card.Because riveting equipment occupied space is big, weight weight when riveting, there are significant limitation, structures for connection between profile and profile piece
Space, which not enough often leads to riveting process, cannot achieve.Now it is badly in need of a kind of connection structure solved between aluminum profile.
Summary of the invention
The technical problems to be solved by the present invention are: when solving aluminum profile connection because riveting equipment occupied space is big cannot
The problem of riveting.A kind of sectional material joint is designed, is riveted between aluminum profile by sectional material joint, the tie point after riveting has enough
Strength and stiffness, be able to satisfy car body rigidity requirement, while riveting process is simpler efficiently simplifies riveting process, allow riveting
Connection technology is on vehicle body using more universal.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of body platform crossbeam and door
Sill beam connection structure, including aluminum profile connector, floor crossmember and sill strip, the aluminum profile connector include integrally formed first
First joint face of joint face, the second joint face and third joint face, the aluminum profile connector connects by the way that FDS connection type is fixed
It connects on floor crossmember, the second joint face of the aluminum profile connector and the interior side elevation of sill strip are solid by FDS connection type
It is fixed, it is fixedly connected between the third joint face and the end of sill strip of the aluminum profile connector by self-plugging rivet.
Preferably, being provided with reinforcing rib between the first joint face and the second joint face of the aluminum profile connector.
Preferably, the region that aluminum profile connector is in contact with floor crossmember, sill strip is attached fixation by MIG repair welding.
Preferably, being provided on the first joint face of the aluminum profile connector, the second joint face and third joint face predetermined
Position hole.
Compared with prior art, usefulness of the present invention is: connecting between floor crossmember, sill strip, connector, passes through frock clamp
Positioning clamps, and completes riveting with FDS, core pulling riveting, the assembly tie point after riveting has enough stiffness and strength.Floor is horizontal
Beam, sill strip and connector are aluminium extruded section, no die cost, and because riveted joint is structurally reasonable when riveting, technique is simpler
It is single, it connects relatively reliable.
Detailed description of the invention:
The following further describes the present invention with reference to the drawings.
Fig. 1 is the structural schematic diagram of aluminum profile connector.
Fig. 2 is the attachment structure schematic diagram of aluminum profile connector and floor crossmember.
Fig. 3 is the outside structure diagram of connecting assembly.
Fig. 4 is the inside structure schematic diagram of connecting assembly.
Specific embodiment:
The present invention will be described in detail With reference to embodiment:
A kind of body platform crossbeam and sill strip connection structure as shown in Figures 1 to 4, including aluminum profile connector 1, floor crossmember
2 and sill strip 3, the aluminum profile connector 1 includes integrally formed first joint face 11, the second joint face 12 and third joint face
13, the first joint face 11 of the aluminum profile connector 1 is fixedly connected on floor crossmember 2 by FDS connection type, the aluminium profiles
The interior side elevation of the second joint face 12 and sill strip 3 of material connector 1 is fixed by FDS connection type, the aluminum profile connector 1
It is fixedly connected between third joint face 13 and the end of sill strip 3 by self-plugging rivet 4.
Floor crossmember 2 and aluminum profile connector 1 are assembled, positioning clamping is carried out to two parts with frock clamp, passes through FDS work
Skill is attached fixed composition component one.Component one is assembled together with sill strip, two parts are determined with frock clamp
Position clamps, and is attached fixation by FDS technique and self-plugging rivet 4, just completes the company of floor crossmember, connector and sill strip
It connects.
Core of the invention is by designing extrudate connector, and the cooperation of control joint size and floor crossmember sectional dimension is closed
System.Connector and floor crossmember are positioned by frock clamp within the scope of manufacturing tolerance and clamped, is fixed with FDS, formation group
Then component and sill strip are carried out positioning clamping by frock clamp again by part, be fixed on one with FDS, high-intensitive self-plugging rivet
It rises.The assembly sequency of floor crossmember, sill strip and connector three can convert.Such as: first connector is connect with floor crossmember solid
It is fixed, form component, then connect with sill strip or be first connected and fixed connector and sill strip again, formation component, then again with
Floor crossmember connection.Convenience flexible choice when can be according to practical set installs order.
In order to increase the whole use intensity of aluminum profile connector 1, the first joint face 11 of the aluminum profile connector 1 is connect with second
Reinforcing rib is provided between face 12.
After completing assembly connection, region that aluminum profile connector 1 is in contact with floor crossmember 2, sill strip 3 pass through MIG repair welding into
Row is connected and fixed, and can improve the stiffness and strength of tie point position.
In addition, carrying out positioning clamping, the first joint face of the aluminum profile connector 1 to two parts for the ease of frock clamp
11, pre-determined bit hole is provided on the second joint face 12 and third joint face 13.
It is emphasized that: it is obvious to a person skilled in the art that the present invention is not limited to the above exemplary embodiments is thin
Section, and without departing from the spirit or essential characteristics of the present invention, the present invention can be realized in other specific forms.
Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, model of the invention
It encloses and is indicated by the appended claims rather than the foregoing description, it is intended that the meaning and model that the equivalent requirements of the claims will be fallen in
All changes in enclosing are included within the present invention.
