Abstract
The utility model discloses a kind of saloon car rear floor spare wheel pool structure, it is characterized in that: the bottom surface (1) of described spare tyre pool structure is step-like progressively recessed in three grades, a boss (2) is provided with in the center of bottom surface (1), centered by boss (2), be radially distributed with one group of reinforced rib along bottom surface to sidewall penetration type, this reinforced rib is concave bar (3).The utility model is by the reinforced rib of alternative arrangement, improve significantly to spare tyre pond rigidity, mode, during welding, improve the problem stepping on spare tyre pond plastic deformation, and promote car load NVH performance, avoid in the process of running car, occur spare tyre pond low-frequency resonance phenomenon, reduce the risk of spare tyre pond cracking in the examination of road.During painting electrophoresis, electrophoresis liquid is collected along the step surface of concave bar and bottom surface to center lowest surfaces, and the quantity of liquid-leaking nozzle is reduced 1 ~ 2, thus reduces the quantity of blocking piece, reduces costs, and is worth industrially promotion and application.
Description
Technical field
The utility model relates to auto body field, especially relates to a kind of saloon car rear floor spare wheel pool structure.
Background technology
The NVH performance of automobile is the standard of the evaluation automotive performance quality that latest developments are got up.The structure design of car body each several part all should consider the impact on auto NVH performance.Spare tyre pond, floor is place the place of spare tyre, and spare tyre pond is deep draw region, more special to the performance requriements of material herein, therefore causes the yield strength of selected material herein lower.Cause spare tyre pond rigidity and mode bad.As in welding process, step down in panel beating plastic deformation on spare tyre pond, affect client's sensory evaluation, in driving procedure, affect car load NVH performance, and occur low-frequency resonance, the problem of spare tyre pond cracking in causing road to be tried; In driving process, be easy to, because resonance causes the generation of noise in car, reduce NVH performance, affect the quality of vehicle.Therefore structure design herein just seems particularly important.In order to improve performance herein, the method for conventional enhancing rigidity is that the rear flooring material of replacing or increase material material are thick, or increases reinforcement in spare tyre attachment point peripheral region, rear floor.
The equal Shortcomings part of above-mentioned improved procedure: more conversion materials can increase Sheet Metal Forming Technology difficulty, changes and expects that thick or increase reinforcement can make tare rise, reduce fuel economy, cost can be made simultaneously to increase.And rigidity and the Modal Performances in spare tyre pond, floor is improved by favorably situated reinforced rib, be more and more used.
Utility model content
Given this, the purpose of this utility model is to provide a kind of saloon car rear floor spare wheel pool structure, solve the problem that existing spare tyre pond rigidity is not high, by reasonable Arrangement reinforced rib, rear floor spare tyre pool structure rigidity and mode are improved, improve the panel beating distortion of spare tyre pond and car load NVH performance, and avoid low-frequency resonance phenomenon occurs.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of saloon car rear floor spare wheel pool structure, its bottom surface be three grades step-like progressively recessed, be provided with a boss in the center of bottom surface, centered by boss, be radially distributed with one group of reinforced rib along bottom surface to sidewall penetration type, this reinforced rib is concave bar.Electrophoresis liquid can pool together along the step surface of concave bar and bottom surface to center lowest surfaces, is furnished with three liquid-leaking nozzles at junction.The width of above-mentioned concave bar is 30 ~ 50mm, and the degree of depth is 5 ~ 10mm.Adopt technique scheme, by arranging the bottom surface of spare tyre pool structure in step-like, and arrange radial concave bar, and then improve rigidity and the mode in rear spare tyre pond, floor, improve the panel beating distortion of spare tyre pond and car load NVH performance, avoid the generation of low-frequency resonance phenomenon.
The beneficial effects of the utility model: the utility model is more simple than existing spare tyre pool structure, and punching press formability is good.First by the bottom surface of spare tyre pool structure is arranged in step-like, and radially one group of concave bar is distributed with along bottom surface to sidewall penetration type centered by the boss of bottom surface, spare tyre pond rigidity, mode is made to improve significantly, the utility model effectively prevent and occur spare tyre pond low-frequency resonance phenomenon in the process of running car, reduces the risk of spare tyre pond cracking in the examination of road.During painting electrophoresis, electrophoresis liquid is collected along the step surface of concave bar and bottom surface to center lowest surfaces, and the quantity of liquid-leaking nozzle is reduced 1 ~ 2, thus reduces the quantity of blocking piece, reduces costs, and is worth industrially promotion and application.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is birds-eye view of the present utility model.
Fig. 2 is block diagram of the present utility model.
Wherein, 1, bottom surface; 2, boss; 3, concave bar; 4, liquid-leaking nozzle; 5, the first concave bar; 6, the second concave bar.
Detailed description of the invention
Embodiment,
Refer to Fig. 1, with headstock direction for front end, tailstock direction is rear end.Saloon car rear floor spare wheel pool structure, its first half shape is semicircular arc with spare tyre profile, and latter half extends along circular arc tangential line direction.
Wherein, the bottom surface 1 of spare tyre pool structure is step-like progressively recessed in three grades, is provided with a boss 2, for the face of weld of wheel support in the center of bottom surface 1; Centered by boss 2, be radially distributed with one group of reinforced rib along bottom surface to sidewall penetration type, this reinforced rib is concave bar 3, and its width is 30 ~ 50mm, and the degree of depth is 5 ~ 10mm, and concave bar is uniform and quantity is intensive; Spare tyre pond also offers three liquid-leaking nozzles 4.During painting electrophoresis, electrophoresis liquid is collected along the step surface of concave bar and bottom surface to center lowest surfaces, and liquid-leaking nozzle is arranged on this junction.
In the semi arch region of spare tyre pool structure front portion, with uniform at least 5 reinforced ribs of decile angle, run through sidewall along second-order bottom surface; Latter half is centered by boss, and arc type is evenly arranged at least 6 muscle.
Refer to Fig. 2, in order to dispersive stress is concentrated, by cae analysis, improve first concave bar 5, second concave bar 6 liang of places in above-mentioned reinforced rib, wherein, the first concave bar 5 is positioned at the center in the semi arch region of spare tyre pool structure front portion; Second concave bar 6 is positioned at the center, bottom surface 1 of spare tyre pool structure:
1, for the first concave bar, change termination into outer splayed by uniform cross section, dispersive stress is concentrated.
2, for the second concave bar, by the development length of this muscle from lateral wall shortens to R angle, bottom surface root, i.e. the sidewall of spare tyre pool structure and bottom surface intersection.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as adopt the various improvement that method of the present utility model is conceived and technical scheme is carried out; or directly apply to other occasion, all within protection domain of the present utility model without improving.
