Abstract
The invention relates to a rear apron board of an automotive body. The rear apron board comprises a board body and is characterized in that the left lower part of the board body is provided with a first X-shaped reinforcing rib, and the right lower part of the board body is provided with a second X-shaped reinforcing rib; the middle upper part of the board body is provided with a first horizontal reinforcing rib, the middle lower part of the board body is sequentially provided with a second horizontal reinforcing rib, a third horizontal reinforcing rib and an S-shaped reinforcing rib from top to bottom; and a first vertical reinforcing rib and the second vertical reinforcing rib are arranged between the first horizontal reinforcing rib and the second horizontal reinforcing rib. Because the rear apron board is provided with the first X-shaped reinforcing rib and the second X-shaped reinforcing rib, local rigidity of the point of the reinforcing ribs is improved, the additional arrangement of a reinforcing plate at the reinforcement point is avoided, the weight of the automotive body is reduced, and the cost is saved. Because the two horizontal reinforcing ribs and the two vertical reinforcing ribs are connected in a square shape, the static rigidity and the dynamic rigidity of a metal plate at the point are obviously improved, and the vibration resistance is improved.
Description
Technical field
The invention belongs to automobile body components, be specifically related to skirtboard behind a kind of auto body.
Background technology
Along with the transformation of automobile consumption idea, the customer more and more payes attention to NVH (Noise, the noise of automobile when paying attention to conventional security performances such as whether vehicle body ftractures; Vibration, vibration; Harshness, uncomfortable property) performance, the quality of NVH performance affects a car to a great extent and whether is in great demand.Therefore, the equal great strength of each big auto vendor promotes the NVH performance of automobile, and common practice is to reduce perhaps acoustics packing on auto body of automobile driving source vibration, to reduce the vibration noise of client, and often method difficulty or cost increase; And the Optimal Structure Designing on the vehicle body panel beating panel (panel constructions such as closure member, top cover, floor, dash shield, back skirtboard) of transmitting vibrations noise comparatively lags behind, and also is that increase panel beating thickness, the local brace panel of increase improve sheet metal component rigidity and avoid the transmitting vibrations noise usually.Below all reduced the automobile cost performance.Event needs the plates of automobile structure that a kind of rigidity is high, in light weight, vibration performance is good.
Summary of the invention
For solve skirtboard rigidity behind this car vehicle body more weak and be prone to cause that the problem of vibration noise, the present invention provide that a kind of rigidity is high, in light weight, skirtboard behind the auto body that can reduce car load vibration and noise level.
Skirtboard behind a kind of auto body of the present invention comprises plate body, it is characterized in that: the lower left quarter at said plate body is provided with first " X " shape reinforced rib, is provided with second " X " shape reinforced rib at the right lower quadrant of said plate body;
Be provided with the first horizontal reinforced rib in the middle and upper part of said plate body, be provided with the second horizontal reinforced rib, the 3rd horizontal reinforced rib from top to bottom successively in the middle and lower part of said plate body with the serpentine reinforced rib;
Between the said first horizontal reinforced rib and the second horizontal reinforced rib, be provided with first vertical strengthening ribs and second vertical strengthening ribs, this twice vertical strengthening ribs and the horizontal reinforced rib of twice are connected to form " mouth " shape structure.
Skirtboard behind described a kind of auto body between said serpentine reinforced rib and second " X " shape reinforced rib, also is provided with the 4th horizontal reinforced rib and the 5th horizontal reinforced rib from top to bottom successively.
Further, the lower end of edge, stage casing and first " X " the shape reinforced rib of said serpentine reinforced rib and second " X " shape reinforced rib flushes.
Further, the length of the said the 5th horizontal reinforced rib is greater than the 4th reinforced rib, and the lower end of lower edge and second " X " the shape reinforced rib of the 5th horizontal reinforced rib flushes.
The present invention has following advantage:
1) owing to be provided with first " X " shape reinforced rib and second " X " shape reinforced rib, thereby improved the local stiffness at this place, avoided playing the muscle place and set up brace panel, reduced tare, practiced thrift cost at this;
2) because the horizontal reinforced rib of twice is connected with the twice vertical strengthening ribs and is " mouth " font, make the quiet rigidity and the dynamic stiffness of this place's panel beating significantly improve, promoted the anti-vibration performance;
3) because horizontal reinforced rib, vertical strengthening ribs and " X " type reinforced rib cooperatively interact, promoted the rigidity property of whole back skirtboard, strong support is provided practicing thrift cost, the vibration of reduction car load and noise level.
Description of drawings
Fig. 1 is the structural representation of skirtboard behind the present invention.
The specific embodiment
Further specify structure of the present invention below in conjunction with accompanying drawing.
Referring to skirtboard behind a kind of auto body shown in Figure 1, plate body is a sheet-metal member, is provided with first " X " shape reinforced rib 2 at the lower left quarter of plate body 1, is provided with second " X " shape reinforced rib 3 at the right lower quadrant of said plate body 1;
Be provided with the first horizontal reinforced rib 4 in the middle and upper part of plate body 1, be provided with second horizontal reinforced rib the 5, the 3rd horizontal reinforced rib 6 from top to bottom successively in the middle and lower part of plate body 1 with serpentine reinforced rib 7;
Between the first horizontal reinforced rib 4 and the second horizontal reinforced rib 5, be provided with first vertical strengthening ribs 8 and second vertical strengthening ribs 9, this twice vertical strengthening ribs and the horizontal reinforced rib of twice are connected to form " mouth " shape structure.
Further, between serpentine reinforced rib 7 and second " X " shape reinforced rib 3, also be provided with the 4th horizontal reinforced rib 10 and the 5th horizontal reinforced rib 11 from top to bottom successively.
Further, the lower end of edge, stage casing and first " X " the shape reinforced rib 2 of serpentine reinforced rib 7 and second " X " shape reinforced rib 3 flushes.
Further, the length of the said the 5th horizontal reinforced rib 11 is greater than the 4th reinforced rib 10, and the lower end of lower edge and second " X " the shape reinforced rib 3 of the 5th horizontal reinforced rib 11 flushes.
The about 20mm of width of first " X " shape reinforced rib 2 and second " X " shape reinforced rib 3.
First vertical strengthening ribs 8 and second vertical strengthening ribs 9 are arranged in skirtboard middle part, back, the about 25mm of width, and with respect to XZ (Y=0) plane left-right symmetric, both are at a distance of about 50mm, the about 90mm of vertical extension.
The right section bending extension that is inclined upwardly of serpentine reinforced rib 7 is with second " X " shape reinforced rib, 3 common parcel the 4th horizontal reinforced rib 10 and the 5th horizontal reinforced ribs 11.
More than each reinforced rib play the muscle direction all to vehicle body rear (positive directions X), play the about 5mm of muscle height, and determine it to play the muscle chamfering according to factors such as technological formings.
Further feature muscle on the back skirtboard, position, hole information according to the function of back skirtboard, with peripheral body structure coupling its layout of decision and form.
