Abstract
The invention discloses a kind of automobile rear floor reinforced support, this rear floor reinforced support is the U-shaped Troffer of cross-sectional plane, its upper end is used for welding with rear wheel cover reinforcement, rear wheel cover strut member, its lower end is provided with for welding flange with first of rear floor welded, and the top of its two side is provided with second welds flange for what weld with rear wheel cover and floor side member.This rear floor reinforced support efficiently reduces the deflection of the landing edge of rear wheel cover and floor side member, improves the fatigue resistance of rear wheel cover, avoids rear wheel cover and easily cracks.
Description
Technical field
The present invention relates to the parts of automobile, relate to a kind of automobile rear floor reinforced support in particular.
Background technology
The connection structure of existing automobile rear floor and its Surrounding Parts as shown in Figure 4, comprise rear floor 2, rear wheel cover 3, floor side member 4, rear wheel cover reinforcement 5, rear wheel cover strut member 6 and shelf 7, described floor side member 4 is positioned at the below on rear floor 2, weld with the lower surface on rear floor 2 and flanging side face respectively, described rear wheel cover 3 is positioned at the outside on rear floor 2, its lower end is welded with floor side member 4, its upper end is welded with rear wheel cover reinforcement 5, described shelf 7 welds with rear wheel cover reinforcement 5, rear wheel cover strut member 6 is welded with between the lower surface and rear wheel cover 3 inside face of shelf 7.
When rear wheel cover bears the power F that car chassis passes over, power F upwards passes through rear wheel cover reinforcement 5, rear wheel cover strut member 6, shelf 7 transmitting force f1 to body top section and opposite side, downward path is by rear wheel cover 3 transmitting force f2 to floor side member 4 lateral surface, and additional bending moment M makes the landing edge of rear wheel cover 3 lower end and floor side member 4 yielding; The action effect sharing power due to f2 is bad, and f1 causes more greatly additional bending moment M comparatively large, under the reverse load effect of chassis, easily rear wheel cover endurance failure occurs, produces vehicle body crackle, affects vehicle body service life.
Summary of the invention
The object of this invention is to provide a kind of automobile rear floor reinforced support, to reduce the stress of rear wheel cover lower end and floor side member lap-joint, improve the fatigue resistance of rear wheel cover.
Automobile rear floor reinforced support of the present invention, this rear floor reinforced support is the U-shaped Troffer of cross-sectional plane, its upper end is used for welding with rear wheel cover reinforcement, rear wheel cover strut member, its lower end is provided with for welding flange with first of rear floor welded, and the top of its two side is provided with second welds flange for what weld with rear wheel cover and floor side member.
Automobile rear floor reinforced support of the present invention, its upper end is welded with rear wheel cover reinforcement, rear wheel cover strut member respectively, and its lower end and rear floor welded, the top of its two side is welded with rear wheel cover.Rear wheel cover reinforcement and rear wheel cover strut member are by the upper end closed of rear floor reinforced support, rear floor is by the lower end closed of rear floor reinforced support, rear wheel cover is by the top closure of its two side, rear floor reinforced support is made to have welded the closed cavity body structure of rear formation one with its Surrounding Parts, firm structure stiffness is higher, and is conducive to absorbing energy.When rear wheel cover bears the power that car chassis passes over, rear floor reinforced support can by a part of force transmission to shelf, rear floor and floor side member, decrease the moment of flexure of the lap-joint of rear wheel cover lower end and floor side member, namely the deflection of the landing edge of rear wheel cover and floor side member is efficiently reduced, improve the fatigue resistance of rear wheel cover, avoid rear wheel cover and easily crack.

Fig. 2 is the structural representation of the present invention and its Surrounding Parts;
Fig. 3 is the section-drawing along AA line in Fig. 2;
Fig. 4 is the structural representation of existing automobile rear floor and its Surrounding Parts.
Detailed description of the invention
In order to explain technical scheme of the present invention further, below by coming by reference to the accompanying drawings, the present invention will be described in detail.
As shown in Figure 1, this automobile rear floor reinforced support 1 is the U-shaped Troffer of cross-sectional plane, its upper end is used for welding with rear wheel cover reinforcement 5 and rear wheel cover strut member 6, its lower end is provided with first welds flange 12 for what weld with rear floor 2, and the top of its two side is provided with second welds flange 8 for what weld with rear wheel cover 3 and floor side member 4.
The annexation of this automobile rear floor reinforced support and its Surrounding Parts as shown in Figures 2 and 3, the upper end of rear floor reinforced support 1 one sidewall protected by the first via hole 10 and rear wheel cover reinforcement 5 solderedly to connect, the upper end of another sidewall of rear floor reinforced support 1 and diapire protects soldered connecing by the second via hole 11 with rear wheel cover strut member 6.The lower end of rear floor reinforced support 1 is welded with rear floor 2 by the first welding flange 12, and the top of its two side is welded with rear wheel cover 3 by the second welding flange 8.Rear wheel cover reinforcement 5 and rear wheel cover strut member 6 are by the upper end closed of rear floor reinforced support 1, rear floor 2 is by the lower end closed of rear floor reinforced support 1, rear wheel cover 2, by the top closure of its two side, makes rear floor reinforced support 1 weld the closed cavity body structure of rear formation one with its Surrounding Parts.
When rear wheel cover 3 bears the power F that car chassis passes over, because the upper end of rear floor reinforced support 1 is welded with rear wheel cover reinforcement 5 and rear wheel cover strut member 6, form the path of upwards power transmission f3.Soldering turret electrode 13 passes from the 3rd via hole 9, is connected on rear floor 2 with rear wheel cover 3 lower end by spot welding 14, forms the path of downward power transmission f4.The sidewall of rear floor reinforced support 1 is connected with rear wheel cover 3 by the second flange, and the lower end of the second flange is welded with floor side member 4, and the lower end of rear floor reinforced support 1 is connected with rear floor 2 by spot welding, forms the path of downward power transmission f5.Chassis Input Forces F is shared by f3, f4, f5, relative to existing structure, due to newly-increased f5 power transmission, f4 is made to be less than f2, f3 is less than f1, thus additional bending moment M is reduced, the stress that the landing edge place reducing rear wheel cover 3 root and floor side member 4 bears, effectively reduces the deflection of the landing edge of rear wheel cover 3 and floor side member 4.
