Abstract
The invention discloses a rear floor margin plate of an automobile. The margin plate consists of a rear floor margin plate front section, a rear floor margin plate rear section and reinforcers, wherein the rear floor margin plate front section and the rear floor margin plate rear section are all L-shaped, and mutually welded to form a margin plate main structure; two parallel reinforcers are welded at the inner side of the rear floor margin plate front section and correspond to the position welded with a rear suspended damping spring support at the bottom of the rear floor margin plate front section; the reinforcers are vertical to two L-shaped surfaces of the rear floor margin plate front section; a semi-enclosed reinforcing structure for reinforcing the rear-suspended damping spring support is formed by enclosure of the two reinforcers and the two L-shaped surfaces of the rear floor margin plate front section; the upper edge of the rear floor margin plate front section is provided with sectional turnups; and a plurality of parallel ribbings are distributed on the rear floor margin plate rear section, gradually enlarged from back to forth, and arranged in a scattered way. The rear floor margin plate has the advantages of using less part, effectively improving welding technology, improving the intensity of the automobile rear-suspension system and the finished automobile, and improving riding comfort of passengers.
Description
Technical field
The invention relates to automotive body structure, particularly, the invention relates to a kind of rear floor margin plate of automobile structure.
Background technology
Rear floor margin plate of automobile is the important composition parts of automotive floor panel assembly, its upper edge will be connected with the floor, back, the bottom will be welded with longeron, and front and back also will partly connect wheel hub bag and back skirtboard, so its structural strength has a direct impact the strength and stiffness of body shell.All there is defective in the rear floor margin plate of present many automobiles on structure design, adopt whole stamping forming single piece such as rear floor margin plate, is unfavorable for the stock and the transportation of punch forming and part; Reinforcement or additional strengthening that rear floor margin plate uses are less, and Position Design is unreasonable etc., causes its intensity not high, can occur distortion or cracking in the time of serious, causes safety misadventure hidden danger; To after the suspend support zone of damping spring do not have special structure to strengthen design, cause rear overhang system unbalance stress, instability.
The said structure design is also unreasonable, causes body shell intensity and rigidity relatively poor, and occupant's travelling comfort is reduced, and very big for aspects such as the life-span influence of vehicle body,
Summary of the invention
The technical problem to be solved in the present invention is the shortcoming that overcomes prior art, provides that a kind of reasonable in design, assembling are simple, intensity rear floor margin plate of automobile structure preferably.
Technical scheme of the present invention is as follows:
A kind of rear floor margin plate of automobile, described side plate is made up of rear floor margin plate leading portion and rear floor margin plate back segment and reinforcement, and rear floor margin plate leading portion and rear floor margin plate back segment are L shaped, and welding forms the side plate agent structure mutually; In rear floor margin plate leading portion inboard, position corresponding to the damping spring support that after the welding of rear floor margin plate leading portion bottom, suspends, weld two parallel reinforcements, reinforcement is vertical with two faces of the L of rear floor margin plate leading portion, two two faces strengthening the L of version and rear floor margin plate leading portion surround together to after the semiclosed additional strengthening that the damping spring support strengthens that suspends.
The upper limb of described rear floor margin plate leading portion has the segmentation flange.
Be distributed with at least 3 parallel beadings on the rear floor margin plate back segment, and progressively increase dispersed placement to front distance by the back.
Described two reinforcements have knock hole at a distance of 45mm on the reinforcement.
Rear floor margin plate of automobile structure of the present invention compared with prior art has following advantage:
1, this side plate structure has adopted simple partitioned organization, and the segmentation welding helps drawing and part stock and transportation.
2, this side plate structure supports correspondence position at the back suspension spring has increased reinforcement, symmetric design, make side plate carry herein stressed evenly, when automobile bumpiness, can be better with stressed dispersion, effectively dissolve, bear and guide impulsive force, thereby thereby improve the cushioning ability of rear overhang system of automobile and the service life of side plate from shock mitigation system.
3, reasonable in design to the layout of two reinforcements distance, can make full use of the finite space of side plate, reach and strengthen vehicle body and reverse requirement with rigidity, increased the stability of rear overhang system, for the occupant provides the more comfortable environment of taking.
4, reinforcement has two circular holes when satisfying intensity, has both effectively utilized this location, hole, can reduce the weight of part again.
5, in rear floor margin plate back segment branch beading is arranged, and by back segment forward progressively distance increase dispersed placement, help strengthening part strength, and played the collision energy-absorbing effect, improve the anti-collision capacity that knocks into the back of automobile.
Description of drawings
Fig. 1 is the assembly axonometric drawing of rear floor margin plate of automobile structure.
Fig. 2 is the front view of rear floor margin plate of automobile structure.
The specific embodiment
Referring to Fig. 1 and Fig. 2, rear floor margin plate of automobile is made up of rear floor margin plate leading portion 2, rear floor margin plate back segment 1 and two reinforcements 3.The cross section of rear floor margin plate leading portion 2 and rear floor margin plate back segment 1 is L shaped, welding forms the side plate agent structure mutually, its upper limb is welded to connect by the back floor of flange and automobile, L shaped bottom surface and automobile longitudinal girder are welded to connect, the front end of rear floor margin plate leading portion 2 also welds with rear floor margin plate, the front end lower edge has one section arc flange, is used for and the welding of wheel hub bag, and the rear end of rear floor margin plate back segment 1 is welded to connect the back skirtboard.
Be welded with two parallel reinforcements 3 in the inboard of rear floor margin plate leading portion 2, the position that its position of weld is supported corresponding to the damping spring that suspends below the L type bottom surface of rear floor margin plate leading portion and after the installation of longeron one welding, reinforcement 3 is vertical with two faces of the L of rear floor margin plate 2, two two faces strengthening the L of version 3 and rear floor margin plate leading portion 2 surround together to after the damping spring that suspends support the semiclosed additional strengthening of strengthening.Reinforcement 3 has knock hole at a distance of 45mm on the reinforcement 3 in addition.
In addition, have segmentation flange 4 at the upper limb of rear floor margin plate leading portion, flange height 18mm is distributed with 5 parallel beadings 5 on the rear floor margin plate back segment 1, and by after increase gradually for example forward, dispersed placement, actv. improves part life and intensity.
