Abstract
The utility model relates to a new energy automobile and a floor lower girder structure of the new energy automobile. The floor lower girder structure comprises a pair of girders located at doorsills of the lower portions of floors on the two sides of an automobile body respectively, the inner side of each girder is welded to the corresponding floor of the automobile body, and the outer side of each girder is welded to the corresponding doorsill of the automobile body. By the adoption of the structure, each girder and the corresponding doorsill form a cavity, the strength of the girder structure is improved, the transverse crumpling amount of the automobile body during side impact is reduced, and passengers and a battery are protected.
Description
Technical field
The utility model relates to the production field of new-energy automobile, is specifically related to girder work under the floor of new-energy automobile.The utility model also relates to a kind of new-energy automobile that comprises girder work under above-mentioned floor.
Background technology
For body construction design, new-energy automobile is to have increased all larger batteries of a volume and weight with respect to traditional fuel vehicle maximum difference.The battery of new-energy automobile is usually placed in body platform bottom.The layout of battery makes new-energy automobile, with respect to traditional fuel vehicle structure, larger variation occur.The longeron of tradition fuel vehicle is by middle part, floor, and in new-energy automobile, battery has taken the position of traditional fuel vehicle longeron, can only lean on the girder work at threshold place, bottom, floor to make up, and the battery of new-energy automobile is also arranged on this longeron, so under the floor of new-energy automobile, girder work will have very high intensity.
Under new-energy automobile floor, as shown in Figure 1, Fig. 1 central sill 1 is the longeron designing for making up girder construction that new-energy automobile lacks in the relative traditional vehicle of battery location to girder work.In prior art, longeron both sides are all overlapped on floor.The crucial attachment point of arranging battery on beam, bears battery weight.The weight of this structure battery is carried on longeron, and passes to floor by longeron, and the weight of battery is finally born by individual layer floor, body construction intensity a little less than.In addition, only have individual layer floor to exist between the closed housing that longeron and floor form and threshold, when auto against, this individual layer floor is subject to lateral impact forces, and car body can produce along horizontal larger feedback contracting amount, causes car body to produce moderate finite deformation; Because the transverse pitch of battery and longeron inner side is very little, be only 15mm again, cause battery in collision easily to be impacted.
Therefore, girder work under a kind of new-energy automobile floor is provided, makes it have higher intensity, thereby when automobile is subject to lateral impact forces, car body is measured along horizontal feedback contracting, improve the safety of auto body and battery, with regard to becoming those skilled in the art, need the problem of solution badly.
Utility model content
The technical problems to be solved in the utility model is to provide girder work under a kind of new-energy automobile floor, strengthens the intensity of girder work, and when minimizing automobile is subject to lateral impact forces, car body is measured along horizontal feedback contracting, improves the safety of auto body and battery.
For solving the problems of the technologies described above, under new-energy automobile of the present utility model floor, girder work comprises that the pair of inside of vehicle body both sides is fixed on the girder work of floor downside, the battery of described new-energy automobile is installed on described girder work bottom, and the outside of described girder work is fixed on threshold bottom.
Preferably, described girder work comprises a pair of upper longeron and a pair of lower longeron that is positioned at longeron below, and described upper longeron inner side is fixed on floor downside, and outside is fixed on body sill, described lower longeron inner side is fixed on longeron, and outside is fixed on body sill.
The beneficial effects of the utility model are: girder work inner side is fixed on floor downside; girder work outside is fixed on threshold bottom; make to form cavity between longeron and floor, threshold; improved the intensity of girder work; while having reduced side impact, cross-car is presented contracting amount, has protected the safety of occupant and battery.Further, described girder work comprises a pair of upper longeron and a pair of lower longeron that is positioned at longeron below, has formed two cavitys, has further improved the intensity of girder work.

Fig. 2 is a kind of specific embodiment A-A cross sectional representation of girder work under floor provided by the utility model;
Fig. 3 be as shown in Figure 2 under plate girder work adopt the A-A cross sectional representation of upper and lower two longerons;
Fig. 4 is the birds-eye view of girder work under plate as shown in Figure 2;
Fig. 5 is the structural representation of brace panel 6;
Fig. 6 is the structural representation of brace panel 7.
The specific embodiment
Under new-energy automobile floor, girder work as shown in Figure 1, comprises a pair of longeron 1 that is positioned at floor downside of vehicle body both sides.For longeron, take near vehicle body central axis is inner side, and take away from vehicle body central axis is outside.Longeron inner side is fixed on body platform 3.In order to improve longeron intensity, under new-energy automobile of the present utility model floor, the outside of longeron 1 is fixed on threshold 2 bottoms.This connection mode makes floor 3, longeron 1, threshold 2 form a closed housing, than both sides inside and outside longeron under floor in prior art, is all fixed on the intensity that body platform 3 has strengthened girder work.
In order further to improve the intensity of girder work, girder work can be comprised of two parts: a pair of upper longeron 4 and a pair of lower longeron 5 that is positioned at upper longeron below, described upper longeron 4 inner sides are fixed on floor 3 downsides, outside is fixed on body sill 2, form a closed housing with floor 3 and threshold 2, described lower longeron 5 inner sides are fixed on longeron 4, outside is fixed on body sill 2, form another closed housing with upper longeron 4, by forming the closed housing of two stacks, promoted the intensity of girder work.
Apparently, girder work provided by the utility model is also not limited to the version of above-mentioned upper longeron and lower longeron combination, from theory, can only there is above-mentioned upper girder work or only there is above-mentioned lower girder work, all can meet the object that improves longeron intensity.
The battery of new-energy automobile is arranged on longeron 1, and for convenient for assembly, described girder work below is provided with the first battery mounting hole 8, the second battery mounting hole 10 and battery mounting-positioning holes 9.Battery is arranged in mounting hole site by Bolt Connection.
Because the battery of new-energy automobile is arranged on longeron 1, longeron is born battery weight, for avoiding causing each battery position of mounting hole local deformation of longeron because bearing battery weight load, described battery mounting hole place is provided with brace panel 6 and brace panel 7, brace panel is centered by mounting hole, side plays flange, as shown in Figure 5, Figure 6.The weight of battery is loaded on longeron by brace panel, avoids longeron directly to bear battery weight and produces compared with large deformation, has alleviated the impact of battery on longeron intensity.
Except girder work under above-mentioned floor, the utility model also provides a kind of new-energy automobile that comprises girder work under above-mentioned floor, and other each several part structures of this new-energy automobile please refer to prior art, do not repeat them here.
By reference to the accompanying drawings the preferred specific embodiment of the utility model and embodiment are explained in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken possessing those skilled in the art, can also make a variety of changes without departing from the concept of the premise utility.
