Abstract
The utility model provides a front floor assembly and an automobile, and belongs to the technical field of automobiles. The front floor assembly comprises a front floor, floor front longitudinal beams and front longitudinal beam upper stiffening plates. The front floor comprises a first surface and a second surface, the second surface is opposite to the first surface, and the front longitudinal beam upper stiffening plates are mounted on the first surface, and each floor front longitudinal beam comprises front longitudinal beam back plates which are mounted on the second surface, at least one stiffening beam is arranged on the second surface in a protrusive mode, and the portion, corresponding to the stiffening beam, of the first surface sink towards the corresponding stiffening beam and form a groove. The front longitudinal beam upper stiffening plates cover the corresponding grooves so as to form at least one closed cavity in an encircling mode. By means of the front floor assembly, the strength and the non-deformability ability of the front floor are improved, the probability that the front floor deforms when the automobile is bumped directly is reduced, the survival space of a driver can be increased effectively, and damage on passengers caused by impact is reduced.
Description
Technical field
The utility model relates to automobile technical field, particularly a kind of front floor assembly and automobile.
Background technology
The vehicle body of automobile is the basis of car load, vehicle body lower body especially, and it is the basis of the various aspects of performance such as vehicle security, traveling comfort, reliability.
The leading portion energy-absorption box of the front bumper of vehicle body, front anti-collision beam, left-right longeron is main energy-absorbing, the crumple parts of automobile.If meet accident, the high speed head-on crash can occur in automobile, and under the effect of powerful impact force, the leading portion energy-absorption box of the front bumper of vehicle body, front anti-collision beam, left-right longeron produces the crumple distortion, absorbs and damp impacts power, to reduce the damage distortion of automobile.And opposite, in order to guarantee passenger's residing region security in head-on crash, must guarantee to comprise later on that at front coaming plate A post, front floor assembly zone do not allow larger crumple distortion, to reduce the crumple distortion passenger is damaged.
Planar design is all adopted on the front floor of the vehicle body of existing automobile, and longitudinal strength relies on stiffening plate on floor front side member and the longeron fully.Yet the longitudinal strength in front floor own is relatively poor.In the central collision process, the shrinkage on front floor is large, badly influences passenger's safety.
The utility model content
In view of this, be necessary to provide a kind of intensity that can the front floor of Effective Raise regional area, reduce the crumple space in major-minor driver zone, thereby reduce front floor assembly and automobile to passenger's injury.
In order to address the above problem, according to first aspect of the present utility model, a kind of front floor assembly is provided, it comprises stiffening plate on front floor, floor front side member and the front side member, described front floor comprises that first surface reaches second relative with described first surface, stiffening plate is installed in described first surface on the described front side member, and described floor front side member comprises plate behind the front side member that is installed on described second; Convex with at least one strength beam on described second, and the described first surface position corresponding with each strength beam is recessed to form groove to described corresponding strength beam; Stiffening plate is covered on described groove on the described front side member, and surrounds together at least one closed cavity with described respective slot.
Further, the cross section semicircular in shape of each described groove.
Further, plate comprises at least one host cavity of plate body being installed and being formed by described installation plate body depression behind the described front side member, and described installation plate body is installed on described second, and described strength beam is contained in the corresponding host cavity.
Further, stiffening plate comprises fixed plate body and at least one lid that is bent to form by described fixed plate body on the described front side member, and described fixed plate body is fixed in described first surface, and described lid is covered on described respective slot.
Further, the cross section of each described lid takes the shape of the letter U.
On the other hand, the utility model also provides a kind of automobile, and this automobile comprises vehicle body, and this vehicle body comprises above-mentioned front floor assembly.
The beneficial effects of the utility model:
Front floor assembly of the present utility model and automobile have improved intensity and the non-deformability on front floor by the common closed cavity that forms of stiffening plate on strength beam and front floor and the front side member; Thereby reduced the distortion of front floor assembly in automobile central collision process, living space that can the Effective Raise chaufeur has reduced collision impact and has caused injury to the passenger.
Description of drawings
Fig. 1 represents the part-structure scheme drawing of the utility model automobile, and this automobile comprises front floor;
The partial enlarged drawing on front floor in Fig. 2 presentation graphs 1;
Fig. 3 represents the schematic cross-section of the front floor assembly of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Please in conjunction with reference Fig. 1, the utility model provides a kind of automobile, and it comprises vehicle body.This vehicle body comprises front floor assembly 1.
Front floor assembly 1 comprises stiffening plate 13 on front floor 11, floor front side member (not shown) and the front side member.Front floor 11 comprise first surface 111 with relative with first surface 111 second 113.Please in conjunction with reference Fig. 2, convex with at least one strength beam 115 on second 113, to improve the intensity on front floor 11.The corresponding position of first surface 111 and each strength beam 115 is to corresponding strength beam 115 depressions, to form groove 117.Preferably, the cross section semicircular in shape of each groove 117.
Please in conjunction with reference Fig. 3, the floor front side member comprises plate 12 behind the front side member.Plate 12 comprises at least one host cavity 124 of plate body 121 being installed and being formed by the middle part depression that plate body 121 is installed behind the front side member.The diapire of each host cavity 124 is provided with a through hole 126.Plate body 121 is installed is installed on second 113, and strength beam 115 is contained in the corresponding host cavity 124.
Please in conjunction with reference Fig. 3, stiffening plate 13 comprises the lid 131 that fixed plate body 133 and at least one cross section that is bent to form by fixed plate body 133 take the shape of the letter U on the front side member.Fixed plate body 133 is installed in first surface 111, and lid 131 is covered on corresponding groove 117, to form a closed cavity 15.The reason of closed cavity 15 interior gas pressure intensities, reduce the crumple distortion on front floor 11, intensity, impact resistance and the resistance to bending of front floor assembly 1 have been improved, thereby reduced the distortion of front floor area, living space that can the Effective Raise chaufeur has reduced collision impact and has caused injury to the passenger.
From the above: front floor assembly of the present utility model and automobile have improved intensity and the non-deformability on front floor 11 by the 13 common closed cavities 15 that form of stiffening plate on strength beam 115 and front floor 11 and the front side member; Thereby reduced the distortion of front floor assembly 1 in automobile central collision process, living space that can the Effective Raise chaufeur has reduced collision impact and has caused injury to the passenger.
Above-described only is an embodiment of the present utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
