Description
Technical field
The utility model belongs to body structure technical field, more particularly to a kind of beam structure, preceding floor assembly and vehicle
?.
Background technique
The preceding floor assembly of existing vehicle is welded by punching press sheet metal part, structure type be divided into monoblock type and
Split type two kinds.As depicted in figs. 1 and 2, existing split type front floor of automobile body includes preceding floor panel 1a, preceding connecting plate
2a, left connection board 3a, right connection board 4a, front beam 5a, rear cross beam 6a, front chair connecting plate 7a, back seat connecting plate 8a, left-hand door
Sill inner panel 9a, right threshold internal plate 10a, lower-left stringer 11a, bottom right stringer 12a, lower-left stringer connecting plate 13a and bottom right stringer connect
The inside of fishplate bar 14a, lower-left stringer 11a and bottom right stringer 12a are respectively welded lower stringer liner plate, lower-left stringer connecting plate 13a
Outside and left threshold internal plate 9a weld, the outside of bottom right stringer connecting plate 14a and right threshold internal plate 10a are welded.
In front floor of vehicle body sheet metal forming, lower-left stringer 11a, the bottom right stringer 12a, lower stringer of vehicle body longitudinal direction are generally first passed through
The front beam 5a of liner plate, the lower-left stringer connecting plate 13a of vehicle body transverse direction and bottom right stringer connecting plate 14a and vehicle body transverse direction and
Rear cross beam 6a constitutes the staggered groined type frame of transverse and longitudinal, then by left connection board 3a and right connection board 4a respectively and in left-hand door sill
Plate 9a and right threshold internal plate 10a splicing, it is total with left and right side wall respectively finally by left threshold internal plate 9a and right threshold internal plate 10a
It is shaped to bonding relation.
When head-on crash occurs for vehicle, impact force passes through the lower-left stringer 11a and bottom right stringer 12a, left-hand door on preceding floor
Sill inner panel 9a and right threshold internal plate 10a and floor panel 1a are transmitted backward.Since the channel of front floor of automobile body centre is (by preceding company
Fishplate bar 2a and floor panel 1a composition) structure is simpler, lack the structure that can effectively transmit head-on crash power, so that before vehicle body
The center on floor is bent rapidly under the action of head-on crash power, is caused front floor of automobile body integrally to distort, is jeopardized occupant safety.
When side collision occurs for vehicle, since front floor of automobile body has the staggered groined type frame of transverse and longitudinal, make its opposite side
To impact force transmit to form barrier.Due in the panel construction of existing front floor of automobile body, front beam 5a and rear cross beam 6a it
Between generally use front and back split type structure, at a distance of 350mm or so between front beam 5a and rear cross beam 6a, touched when side occurs for vehicle
When hitting, lateral impact force can not be mutually transmitted between front beam 5a and rear cross beam 6a, lateral impact force can not also be transmitted
It is transferred to the vehicle body other side to floor or by lateral impact force, causes lateral impact force not shunt sufficiently in time, makes vehicle
The impact force of body side is concentrated, and finally be will lead to unilateral crew module's deformation seriously, is seriously threatened occupant safety.
In addition, existing front floor of automobile body assembly uses punching press sheet metal part welding structure, for general arrangement demand, precedingly
It needs to provide installation point on plate for number of modules, but due to the limitation of metal plate punching technique, can not be integrally formed, can only use will
Sheet metal part splits into stamping parts small rack, the small rack scheme with preceding floor welded again.Existing floor assembly structure, on the one hand
Increase stamping die, welding fixture quantity, cost is caused to increase considerably, on the other hand, welding sequence excessively improves welding
Dimension control difficulty, reduces production efficiency.At the same time, excessive sheet metal part welding, floor assembly weight before causing
Measure larger, integration degree is low, and lightweight coefficient is low.
