Abstract
The utility model discloses an automobile front floor, which comprises a body with the cross section in a reverse U shape, wherein a projected part in the middle part of the body is a floor center passage. The utility model is characterized in that the left side of the front part of the floor center passage is provided with a first arc surface and a second arc surface which are downwards recessed, the right side is provided with a third arc surface and a fourth arc surface which are downwards recessed, the left side of the back part of the floor center passage is provided with a downwards recessed fifth arc surface, the right side is provided with a downwards recessed sixth arc surface, and technical liquid leakage holes are arranged in the center of the bottom part of each arc surface. Through the CAE verification, the utility model has the advantages that the rigidity of the novel floor structure is obviously improved through being compared with the original structure, and at the same time, a large number of complicated ribs are omitted, so the stretching and coating manufacturability can be greatly improved, the rigidity and the collision rule requirements of the automobile body structure can be met, in addition, the smooth and fast installation of a chassis and internal and external decorative parts on the automobile body can be ensured, the installation cost is saved, and the assembling precision can be improved.
Description
Technical field
The utility model relates to automobile component, is specifically related to a kind of automobile front floor, is applicable to the vehicle of engine behind front wheel.
Background technology
At present, under the background of soaring oil prices and energy-conserving and environment-protective, the body drawing emphasis is that rigidity and requirement of strength are satisfied in the consideration lightweight simultaneously in the world.Preceding floor level is bigger, need improve strength and stiffness from structure, and wherein good rigidity is to improving member's traveling comfort, and reducing the interior noise of car has important effect.The floor of A00 level vehicle body generally is to adopt the method for arranging the large amount of complex rib to improve the rigidity on floor at present, this design-calculated shortcoming is, rigidity is relatively poor, forming mould is comparatively complicated, increased the moulding difficulty, and be unfavorable for leakage when the electrophoresis workshop section of application workshop, rigidity higher NVH (noise, vibration, sound the shake harsh feeling) performance requriements that can not meet the demands simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of automobile front floor, and it is rational in infrastructure, is easy to moulding, the rigidity height, and crashworthiness is good, can put forward the NVH performance of automobile.
A kind of automobile front floor described in the utility model, comprise that cross-sectional plane is the body of " several " font, the part of body middle part projection is the floor centre gangway, it is characterized in that: be provided with the first recessed cambered surface on the left side of centre gangway front portion, floor and second cambered surface, the right are provided with the 3rd recessed cambered surface and the 4th cambered surface, be provided with recessed the 5th cambered surface, the right on the left side at centre gangway rear portion, floor and be provided with the 6th recessed cambered surface.
Described a kind of automobile front floor, bottom centre in first cambered surface is provided with the first technology liquid-leaking nozzle, bottom centre in second cambered surface is provided with the second technology liquid-leaking nozzle, bottom centre in the 3rd cambered surface is provided with the 3rd technology liquid-leaking nozzle, bottom centre in the 4th cambered surface is provided with the 4th technology liquid-leaking nozzle, bottom centre in the 5th cambered surface is provided with the 5th technology liquid-leaking nozzle, is provided with the 6th technology liquid-leaking nozzle in the bottom centre of the 6th cambered surface.These six technologies play an important role in the coating process of body in white with liquid-leaking nozzle.
The utility model has replaced original complicated rib with recessed cambered surface, through the CAE checking, the ratio of rigidity original structure of this novel floor structure is significantly improved, and simultaneously owing to cancelled the large amount of complex rib, the manufacturability of drawing with application is had greatly improved; Not only satisfy body structure rigidity and collision laws and regulations requirement, and guaranteed that chassis, interior exterior trim part are smooth on vehicle body, fast speed is installed, saved cost of installation, improved assembly precision.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment
Referring to a kind of automobile front floor shown in Figure 1, comprise that cross-sectional plane is the body of " several " font, the part of body middle part projection is a floor centre gangway 15, be provided with the first recessed cambered surface 1 and second cambered surface 2, the right on the left side of centre gangway front portion, floor and be provided with the 3rd recessed cambered surface 3 and the 4th cambered surface 4, be provided with recessed the 5th cambered surface 5, the right on the left side at floor centre gangway 15 rear portions and be provided with the 6th recessed cambered surface 6;
Referring to Fig. 2 and Fig. 3, bottom centre in first cambered surface 1 is provided with first technology liquid-leaking nozzle 9, bottom centre in second cambered surface 2 is provided with second technology liquid-leaking nozzle 10, bottom centre in the 3rd cambered surface 3 is provided with the 3rd technology liquid-leaking nozzle 11, bottom centre in the 4th cambered surface 4 is provided with the 4th technology liquid-leaking nozzle 12, be provided with the 5th technology with liquid-leaking nozzle 7 in the bottom centre of the 5th cambered surface 5, be provided with the 6th technology with liquid-leaking nozzle 8 in the bottom centre of the 6th cambered surface 6.
Can see from accompanying drawing, the arc surfaced that the cross section on floor becomes to rise and fall, entirely board plane one is shared, and six big cambered surfaces have replaced traditional rib shape, and the floor convex rib structure degree of depth that the degree of depth of this cambered surface is more traditional is darker, the degree of depth is about 20mm, and traditional rib height is about 10mm.Six big cambered surfaces are arranged in centre gangway 15 left and right sides, preceding floor respectively, this structure improves a lot the rigidity of structure of floor level, and have the technology liquid-leaking nozzle in the bottom of cambered surface, lay respectively at the bottom centre of cambered surface 1-6, be convenient to the enforcement of coating process, and the quality of application is greatly improved compared with traditional rib floor.
