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 is by the first connecting plate, second
Connecting plate and the integrally formed double T font structures of third connecting plate, first connecting plate, the shape of the second connecting plate are identical, institute
State the first connecting plate, the width dimensions of the second connecting plate are set as the 3/5~3/4 of third connecting plate width dimensions, and described
First connecting plate, the second connecting plate outer end face be aligned with the outer end face of third connecting plate, first connecting plate second connects
Plate passes through FDS connection type and is fixedly mounted on floor crossmember, and the third connecting plate SPR connection type is fixedly mounted on door
On sill beam.
Preferably, the distance between both first connecting plate, second connecting plate outer wall is less than between floor crossmember inner wall
Distance 1mm.
Preferably, the length dimension of the third connecting plate is identical as the length dimension of floor crossmember.
Preferably, being respectively provided in the plate face of the first connecting plate of the aluminum profile connector, the second connecting plate and third connecting plate
There is pre-determined bit 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 to rivet with FDS, SPR, the assembly tie point after riveting has enough stiffness and strength.Floor crossmember, door
Sill beam and connector are aluminium extruded section, no die cost, and because riveted joint is structurally reasonable when riveting, technique is simpler, even
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 main view of aluminum profile connector.
Fig. 2 is the top view of aluminium profile structure.
Fig. 3 is the cross section structure schematic diagram of floor crossmember.
Fig. 4 is the schematic diagram of the section structure of aluminum profile connector, floor crossmember and sill strip connecting assembly.
Fig. 5 is the schematic perspective view of aluminum profile connector, floor crossmember and sill strip 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 5, including aluminum profile connector 1, floor crossmember
2 and sill strip 3, the aluminum profile connector 1 is integrally formed double by the first connecting plate 11, the second connecting plate 12 and third connecting plate 13
T font structure, first connecting plate 11, the shape of the second connecting plate 12 are identical, first connecting plate 11, the second connecting plate
12 width dimensions are set as the 3/5~3/4 of 13 width dimensions of third connecting plate, and first connecting plate 11, second connects
The outer end face of fishplate bar 12 is aligned with the outer end face of third connecting plate 13, the length dimension and floor crossmember of the third connecting plate 13
2 length dimension is identical, and first connecting plate 11, the second connecting plate 12 are fixedly mounted on floor by FDS connection type 4
On crossbeam 2, the third connecting plate SPR connection type 5 is fixedly mounted on sill strip 3.
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, are fixed together with SPR by part.Floor crossmember, threshold
The assembly sequency of beam and connector three can convert, such as: first connector and floor crossmember are connected and fixed, form component, then
It connect with sill strip or is first connected and fixed connector and sill strip again, form component, then connect again with floor crossmember.It can be with
Convenience flexible choice when according to practical set installs order.
For the ease of aluminum profile connector 1 is mounted on floor crossmember 2, both first connecting plate 11, second connecting plate 12
The distance between outer wall is less than distance 1mm between 2 inner wall of floor crossmember.
