Abstract
The invention provides an automobile rear floor cross beam reinforcing structure. The automobile rear floor cross beam reinforcing structure comprises a rear floor cross beam connecting part, a connecting part reinforcing plate, a seat reinforcing plate and a rear frame cross beam. The connecting part reinforcing plate is connected with the rear floor cross beam connecting part in a welded mode, a cavity is formed by the seat reinforcing plate and the rear frame cross beam, and the rear floor cross beam connecting part is connected with the seat reinforcing plate, The rear floor cross beam reinforcing structure comprises two parts so that forming can be promoted, the die development cost and difficulty are reduced, the utilization rate of part materials is high, following production efficiency and quality are guaranteed, and part material thickness matching is optimized; by increasing the thickness of the connecting part reinforcing plate, high stress on a rear floor is reduced in a low-cost state, no reinforcing plate needs to be additionally arranged, and therefore the development cost is reduced.
Description
Technical field
The present invention relates to body of a motor car field, more particularly, to a kind of automobile rear floor reinforcing structure for cross beams.
Background technology
The structure of existing rear floor crossmember is monoblock type, and after its monoblock type, floor crossmember material use is low, difficult forming,
Exist heavily stressed, need the extra reinforcing plate that increases to solve heavily stressed problem, cost increases, and Seat-fixed point Virtual Analysis intensity
Not enough and panel beating type facial disfigurement is larger.
Content of the invention
In order to solve the problems of the prior art, the invention provides a kind of.
The invention provides a kind of automobile rear floor reinforcing structure for cross beams, including after floor crossmember connector, connector add
Strong plate, seat reinforcing plate and Rear frame crossbeam, described connector reinforcing plate and described rear floor crossmember connector pass through welding even
Connect, described seat reinforcing plate forms a cavity with described Rear frame crossbeam, described rear floor crossmember connector is added with described seat
Strong plate connects.
As a further improvement on the present invention, described rear floor crossmember connector is additionally provided with fixing hole, described seat adds
Strong plate is provided with the via corresponding with described fixing hole position.
As a further improvement on the present invention, this automobile rear floor reinforcing structure for cross beams also includes back seat lower plate, described
Back seat lower plate is connected with described seat reinforcing plate upper surface.
As a further improvement on the present invention, described back seat lower plate is also connected with described rear floor crossmember connector.
As a further improvement on the present invention, the thickness of described connector reinforcing plate is more than described rear floor crossmember connector
Thickness.
The invention has the beneficial effects as follows：Floor crossmember reinforcement structure is divided into two parts to be beneficial to molding afterwards, reduces mould
Development cost and difficulty, part material utilization rate high it is ensured that subsequent production efficiency and quality, the optimization of the thick coupling of part material,
Strengthen plate thickness by increasing connector, heavily stressed at floor after reducing under inexpensive state, it is increased without extra reinforcing plate,
Reduce development cost.
Brief description
Fig. 1 is a kind of structural representation of the rear floor crossmember connector of present invention automobile rear floor reinforcing structure for cross beams；
Fig. 2 is a kind of present invention automobile rear floor reinforcing structure for cross beams overall structure diagram；
Fig. 3 is the cross section structural representation at Fig. 2 A-A.
Specific embodiment
Reference：Floor crossmember connector 2- connector reinforcing plate 3- seat reinforcing plate 4- Rear frame crossbeam after 1-
5- back seat lower plate.
As shown in Figure 1 to Figure 3, the invention discloses a kind of automobile rear floor reinforcing structure for cross beams, including after floor crossmember
Connector 1, connector reinforcing plate 2, seat reinforcing plate 3 and Rear frame crossbeam 4, described connector reinforcing plate 2 and described rear floor
Crossbeam connector 1 passes through to be welded together, and is so prevented from the cracking of rear floor crossmember or wrinkling, but also can increase
Plus the stock utilization of connector reinforcing plate 2, the thickness of described connector reinforcing plate 2 is more than described rear floor crossmember connector 1
Thickness, described seat reinforcing plate 3 and described Rear frame crossbeam 4 form a cavity, described rear floor crossmember connector 1 with described
Seat reinforcing plate 3 connects, the stress on floor after can reducing, and is increased without extra reinforcing plate, reduces development cost.
It is additionally provided with fixing hole, described seat reinforcing plate 3 is provided with and described fixed hole position on described rear floor crossmember connector 1
Put corresponding via, the cavity formed by seat reinforcing plate 3 and with described Rear frame, be conducive to transmission and the dispersion of power,
Improve the intensity of fixing hole, reduce panel beating deflection, improve the safety coefficient of Seat-fixed point.
This automobile rear floor reinforcing structure for cross beams also includes back seat lower plate 5, and described back seat lower plate 5 and described seat add
Strong plate 3 upper surface connects, and described back seat lower plate 5 is also connected with described rear floor crossmember connector 1, so can improve seat
Installation strength.
Rear floor crossmember is adopted split-type structural by the present invention, is connected to Rear frame crossbeam 4 by increasing seat reinforcing plate 3
The cavity being formed with seat reinforcing plate 3, by topological optimization, part thickness carries out matching optimization, after reducing under inexpensive state
Heavily stressed at floor, it is increased without extra reinforcing plate, reduces cost of parts, be beneficial to transmission and the dispersion of power simultaneously, improve
Seat-fixed point intensity, reduces panel beating deflection, improves the safety coefficient of Seat-fixed point, realizes part material utilization rate
Raising, lightweight, low cost.
Above content is to further describe it is impossible to assert with reference to specific preferred implementation is made for the present invention
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, some simple deduction or replace can also be made, all should be considered as belonging to the present invention's
Protection domain.
