The specific embodiment
It should be noted that, principle, feature and the advantage of the power transmission for floor for automobile assembly of the present utility model and distressed structure, floor for automobile assembly and automobile will be illustrated by way of example below, yet all descriptions are only used for describing, and they should be interpreted as the utility model is formed to any restriction.In addition, in each mentioned herein embodiment, described or implicit any single technical characterictic, or be shown or lie in any single technical characterictic in each accompanying drawing, still can between these technical characterictics (or its equivalent), proceed combination in any or delete, thereby obtain of the present utility model more other embodiment that may directly not mention in this article.
As previously mentioned, the purpose of this utility model is the feature of operating mode of touching according to vehicle side column, designs better Path of Force Transfer and more rational deformation pattern, thereby a kind of floor assembly power transmission and distressed structure of novelty are provided.According to above mentality of designing, need to consider to guarantee to touch under operating mode and impact force can be passed to threshold at Flank Pole, via threshold, again impact force is delivered to non-collision side; And through optimal design allow and control in channel architecture allow it that a certain amount of distortion occurs, thereby reduce the distortion of occupant side lower floor and threshold, car door.So, by power transmission and the distressed structure of floor assembly and sill strip, just can effectively alleviate the extent of injury of occupant in post touches.
In order to solve the problems of the technologies described above, please refer to shown in Fig. 2, the utility model has provided an exemplary power transmission and distressed structure.Wherein, this power transmission and distressed structure comprise threshold 4, floor 5, single seat crossbeam 6, centre gangway 7, single seat crossbeam 6 is transversely arranged on floor 5 and its two ends are connected with centre gangway 7 with threshold 4 respectively, and centre gangway 7 is arranged in along the longitudinal on floor 5 and is convex.In addition, on threshold 4 and centre gangway 7, be also provided with respectively threshold brace panel and center channel reinforcing plate.So, just by centre gangway 7, formed first area 1 respectively, by single seat crossbeam 6 and floor 5, formed second area 2, and by threshold 4 and threshold brace panel, formed the 3rd region 3, wherein, aspect structural strength, the intensity of above-mentioned second area 2 is greater than the intensity in the 3rd region 3, and the intensity in the 3rd region 3 is greater than the intensity of first area 1, the intensity that is second area 2 is the strongest, is secondly the 3rd region 3, is finally first area 1.By adopting above structure, power transmission that just can be by such floor assembly and sill strip and distressed structure reduce the deflection that touches occupant side lower floor under operating mode and threshold, car door at Flank Pole, effectively protect driver and crew, improve traffic safety performance.
Again as shown in Figure 3, in this preferred embodiment example of the present utility model, can find out the impact force bang path of the power transmission for floor for automobile assembly of the present utility model and distressed structure and the design of deformation pattern.
For the structure going out demonstrated in Figure 3, it should be noted that in design: aspect layout, the direction that single seat crossbeam 6 can be arranged to the impact force F of the input of transmitting when Flank Pole occurring touch is positioned at same longitudinal plane, or and the direction of this impact force F be positioned at two adjacent longitudinal planes (it is upper and lower that the maximum spacing between the two is controlled at 30mm).In addition,, under optional situation, threshold brace panel can be arranged symmetrically in as far as possible to the both sides of single seat crossbeam 6.In addition, under optional situation, center channel reinforcing plate and single seat crossbeam 6 transversely can be arranged in parallel as far as possible.
In above example, for the impact force F from side surface direction, first the 3rd region 3 comes in contact with rigid column, then produces impact force, and first such impact force passes to the 3rd region 3, and also first the 3rd region 3 deforms.When the 3rd region 3 deforms, impact force F is passed through to second area 2.Can requirement be set according to intensity, second area 2 does not deform and just impact force is passed to first area 1, and first area 1 distortion to a certain degree occurs and remaining impact force is delivered to non-shock side (referring to the transmission power f schematically indicating in Fig. 3).In above example, can be designed to after the 3rd region 3 distortion reach predetermined deformation degree, first area 1 just starts to deform, for example in Fig. 3 just with the visualization of Wave curved illustration illustrate the distortion at first area 1 and 3 places, the 3rd region.It should be noted that, only to allow first area 1 that predetermined deformation degree occurs in this example, the 3rd region 3 and first area 1 all stop distortion subsequently, and they will no longer carry the remainder of impact force, but by first area 1, remaining impact force are delivered to non-collision side.
As previously mentioned, according to above these mentalities of designing of the present utility model, can adopt a series of designs and modification to realize impact force transmission and the deformation pattern of novel floor assembly and doorsill structure.Thus, such power transmission and distressed structure installation can be applied on floor for automobile assembly and automobile, thereby give full play of the aforementioned techniques advantage that the utility model has.
More than enumerate example and illustrated in detail the power transmission for floor for automobile assembly of the present utility model and distressed structure, floor for automobile assembly and automobile, these examples are only for explanation principle of the present utility model and embodiment thereof, but not to restriction of the present utility model, in the situation that not departing from spirit and scope of the present utility model, those of ordinary skill in the art can also make various distortion and improvement.Therefore, all technical schemes that are equal to all should belong to category of the present utility model and be limited by every claim of the present utility model.
