Specific embodiment
The application is described in further detail below by specific embodiment and in conjunction with attached drawing.It is described in text
"front", "rear", "left", "right", "upper", "lower" are using the rear floor assembly structure in attached drawing as reference.
As shown in Figure 1, its structural schematic diagram for rear floor assembly structure provided by the present application.The rear floor assembly structure
Including middle plate 1 and back plate 2, middle plate 1 and back plate 2 are an integral molding structure, it is preferred to use Sheet Metal Forming Technology, to realize higher material
Utilization rate and processing efficiency.Middle plate 1 and back plate 2 are respectively equipped with multiple location holes 10 and reinforcing rib 20, and location hole 10 is configured as
It is fixedly arranged on plate 1 and back plate 2 on vehicle body, such as the components such as vehicle seat.Location hole 10 is preferably heavy platform location hole, heavy platform location hole
Setting not only meet process requirements (such as prevent location hole 10 deformation and keep bolt plug connector positioning accuracy), and
And it is conducive to the loss of weight of vehicle body.And reinforcing rib 20 is conducive to floor assembly structure after enhancing then under the premise of not increasing stiffening plate
Intensity.As long as so may be used it is understood that reinforcing rib 20 is arranged in the position that middle plate 1 and back plate 2 are not provided with aperture
The intensity of floor assembly structure after enhancing to the full extent.
Further, fuel tank access hole 11 is preferably ladder mouth-shaped, so when needing leakproof fuel cell access hole 11, lid
Body (not shown) can be sealed with the upper surface of fuel tank access hole 11 and side, i.e. the upper surface and side of fuel tank access hole 11
Face is used as the palette face of lid, so that the sealing performance of fuel tank access hole 11 is more preferable.Part reinforcing rib 20 is examined along fuel tank
The two sides distribution for repairing mouth 11, so when Impact energy is larger, the reinforcing rib 20 being distributed along the two sides of fuel tank access hole 11 can be with
With body distortion to absorb energy, it is ensured that fuel tank access hole 11 not by enormous impact, and then can guarantee fuel system not by
Severe crush damage.
Further, part reinforcing rib 20 is distributed along the whole body that spare tyre places position 21, so improves automobile spare tire placement
The modal stiffness of position 21, springs back after preventing forming parts, reduces the vibration of spare tyre, improve the safety coefficient of automobile.Simultaneously
In order to improve the anti-corrosion ability that spare tyre places position 21, need to coat one layer on the surface that spare tyre places position 21 by way of electrophoresis
Anticorrosive paint, and in order to avoid when electrophoretic painting erosion resistant coating anticorrosive paint spare tyre place position 21 in deposit, in these reinforcing ribs
There is part reinforcing rib 20 through there is coating liquid-leaking nozzle 201 in 20, so many remaining coating can be timely by coating liquid-leaking nozzle 201
Outflow, to make spare tyre place the inside acquisition of position 21 more evenly and smooth corrosion-inhibiting coating, so that extending spare tyre places position
21 service life.Meanwhile the setting of coating liquid-leaking nozzle 201 also mitigates the weight that spare tyre places position 21, makes the design of automobile
More meet lightweight standard, ensure that automobile integrally has more excellent quality.
Further, it is U-shaped structure (i.e. annular section structure) that spare tyre, which places position 21, and its is recessed in back plate 2, recessed
Depth be 60mm-80mm, preferably 70mm, the annular section structure of semi-surrounding has been thusly-formed, effectively to indicate spare tyre
Installation site.It is installed for convenience of spare tyre and fixed, the center that spare tyre places position 21 is equipped with the locating piece 211 for positioning spare tyre.
To guarantee that the tail portion of automobile chassis is unlikely to problem that is too low and causing automobile entirety chassis low, the bottom surface that spare tyre places position 21 is high
Degree need to be designed as (referring to Fig. 2, the difference in height of the two is h) not less than the floor height of middle plate 1.
Please continue to refer to Fig. 1, the two sides of back plate 2 are equipped with flange 22, and flange 22 is configured as with the stringer of automobile (in figure not
Show) it is fixed, it is greatly improved the dimensional stability of flange 22.The specifically whole body that is coated on stringer of flange 22, and by flange
22 are welded on stringer, to realize the fixation of back plate 2 Yu stringer.It is understood that the two sides of middle plate 1 may also set up and turn over
Side, the application is without specifically limiting herein.
Further, multiple salient points 23 for being used to indicate welding region are additionally provided in back plate 2, welding region is located at salient point 23
Lower section, by be arranged salient point 33 can help staff know back plate 2 which region be welding region.
Present invention also provides a kind of automobile, which includes above-mentioned rear floor assembly structure, by using above-mentioned rear ground
Plate assembly structure improves the rear floor strength of automobile, while solving the problems, such as that rear floor is overweight, to accordingly reduce oil
Consumption, correspondingly reduces the use cost of consumer.
Obviously, above-described embodiment of the application is just for the sake of clearly illustrating the application example, and being not is pair
The restriction of presently filed embodiment.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claim of this application within the spirit and principle of application
