Abstract
The invention discloses a rear floor assembly of a passenger car. The rear floor assembly of the passenger car comprises a rear floor body assembly, a rear traction hook reinforcing beam assembly welded to the rear floor body assembly, and a framework assembly formed by a rear floor cross beam assembly and a rear longitudinal beam assembly in a welding mode. The rear longitudinal beam assembly comprises a rear longitudinal beam connection plate, a rear longitudinal beam reinforcing plate, a rear longitudinal beam front section and a rear longitudinal beam rear section, wherein the rear longitudinal beam rear section is connected with the rear longitudinal beam front section through the rear longitudinal beam connection plate in a point welding mode to form a rear longitudinal beam sub-assembly, and the rear longitudinal beam reinforcing plate is welded to the rear longitudinal beam sub-assembly. By means of the rear floor assembly of the passenger car, when a three-cage car is changed into a two-cage car or the two-cage car is changed into the three-cage car, only the rear longitudinal beam rear section needs replacing, namely the change is achieved only by increasing or decreasing the length of the rear longitudinal beam rear section, change of the whole rear longitudinal beam assembly is not needed, and therefore re-development of the rear longitudinal beam assembly caused by the different lengths of rear overhangs is avoided.
Description
Technical field
The invention belongs to the manned vehicle technical field, more precisely, relate to a kind of rear floor structure assembly of manned vehicle.
Background technology
The competition, particularly middle-size and small-size market for automobiles of present domestic motor market, the pace of product renewal is fast, and low-cost high-quality is the major embodiment of competitive power.The body drawing of middle-size and small-size car also will have low-cost and short characteristics of cycle simultaneously pursuing high-quality design, thus the design of the hardware and software platform of vehicle body highlight particularly important.Realize on same lower body platform maximum difficult point that wing-rooms on either side of a one-story house and three-box car maximize to share be after the maximization of floor assembly share, because the difference of three railway carriage or compartments and two-box automobile maximum is exactly the variation that is rear overhang length, rear overhang length is to be determined by the length on rear floor, after rear overhang changes can with minimum cost and failure-free design plan reach share be after the main points that design of floor assembly, be also difficult point.
Summary of the invention
In order to solve problems of the prior art, floor assembly after a kind of manned vehicle is provided, it can satisfy, and the maximization of floor assembly shares after three-box car and two-box automobile.
in order to realize above-mentioned purpose, technical scheme of the present invention is: floor assembly after a kind of manned vehicle, comprise rear floor body assembly, and be welded on rear towing hook strength beam assembly on rear floor body assembly, also comprise by rear floor crossmember assembly, the frame assembly of floor side member assembly weld together, described floor side member assembly comprises back rail junction plate, floor side member brace panel and floor side member leading portion, the floor side member back segment, the floor side member back segment is joined together to form the floor side member branch unit by back rail junction plate and the spot welding of floor side member leading portion, floor side member brace panel and floor side member branch unit weld together.
Preferably, described rear towing hook strength beam assembly comprises rear towing hook deep beam, and the rear towing hook reinforcement vertical beam, the rear towing hook adapter plate that are welded on respectively rear towing hook deep beam both sides.
Preferably, described rear floor crossmember assembly comprises rear floor crossmember body, and the rear floor crossmember connecting panel that is welded on rear floor crossmember body two ends.
Rear floor assembly of the present invention, when three-box car changes two-box automobile or two-box automobile and changes three-box car, only need change floor side member back segment, the length that namely increases or reduce the floor side member back segment can realize, and need not change whole floor side member assembly, avoided causing because of rear overhang length difference the exploitation again of floor side member assembly.Rear floor assembly of the present invention, its cost is low, and in rear floor assembly, a plurality of main parts size can share, and are applicable to a plurality of vehicles, can reduce the input of frock fund.Rear floor assembly of the present invention, its time-to-market is short, just can a plurality of vehicles use as long as do very little change, has reduced the risk of exploitation.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
With reference to figure 1-Fig. 5, floor assembly after a kind of manned vehicle of the present invention, comprise rear floor body assembly 2, and be welded on rear towing hook strength beam assembly 1 on rear floor body assembly 2, consist of a rear floor branch unit, comprise that also rear floor branch unit is welded into rear floor assembly with frame assembly again by the frame assembly of rear floor crossmember assembly 3, floor side member assembly 4 weld togethers.Can realize the switching of this assembly of different automobile types on same secondary welding jig.Rear floor body assembly 2 comprises rear floor body 5 and the back seat adapter plate 6 of weld together.Described floor side member assembly 4 comprises back rail junction plate 8, floor side member brace panel 9 and floor side member leading portion 10, floor side member back segment 7, floor side member back segment 7 is joined together to form the floor side member branch unit by back rail junction plate 8 and 10 spot welding of floor side member leading portion, floor side member brace panel 9 again with floor side member branch unit weld together, consist of floor side member assembly 4.Above-mentioned structure, make when three-box car changes two-box automobile or two-box automobile and changes three-box car, only need change floor side member back segment 7, the length that namely increases or reduce floor side member back segment 7 can realize, and need not change whole floor side member assembly 4, avoided causing because of rear overhang length difference the exploitation again of floor side member assembly.
Preferably, described rear towing hook strength beam assembly 1 comprises rear towing hook deep beam 12, and the rear towing hook reinforcement vertical beam 11, the rear towing hook adapter plate 13 that are welded on respectively rear towing hook deep beam 12 both sides.During welding, rear towing hook body 14 first can be welded together to form rear towing hook adapter plate branch unit with rear towing hook adapter plate 13, rear towing hook is strengthened vertical beam 11 and rear towing hook deep beam 12 is welded together to form rear towing hook strength beam branch unit, after last, towing hook adapter plate branch unit and rear towing hook strength beam branch unit are welded as rear towing hook strength beam assembly, can realize the switching of this assembly of different automobile types on same secondary welding jig.Above-mentioned structure, make when three-box car changes two-box automobile or two-box automobile and changes three-box car, the length of towing hook adapter plate 13 after only needing to increase or reduce has been avoided causing rear towing hook to strengthen the exploitation again of vertical beam 11 or whole rear towing hook strength beam assembly 1 because rear floor body changes.
