Abstract
The utility model relates to a center channel structure of an automobile body bottom plate, which comprises a center channel body and two lateral flanged edges integrally formed with the center channel body. A first concave cavity is axially arranged in the middle of the center channel body; reinforcing ribs are respectively axially arranged on the two lateral flanged edges; a smooth transitional surface with a trapezoidal cross section is disposed in the rear portion of the center channel body; the center channel body increases a lapping surface between the center channel body and a front floor board; and lapping positions are made into the structure of a sealing beam. As the rear portion with the reinforcing ribs and the center channel body is made into the smooth transitional surface, the center channel structure increases transfer paths of forward impact force, improves side-impact performance and solves the problem that passengers in the middle of a rear row have restricted space between legs.
Description
Technical field
The utility model relates to a kind of auto body base arrangement, refers in particular to the middle channel architecture of body bottom panel.
Background technology
Two along with the automotive market competition is more and more fierce, and client is also more and more higher for the requirement of vehicle safety performance.When automobile crashes, protect pedestrian and passenger's personal safety to greatest extent, reduce vehicle and in-built damage thereof as far as possible.Therefore, require vehicle structure design that good collision energy-absorbing and power transmission effect will be arranged, should reduce in the collision process as far as possible, protect occupant safety again as far as possible, also will accomplish to reduce the loss of vehicle pedestrian's extent of injury.
As the body bottom panel part, main purpose does not lie in energy-absorbing, and is the more effective impact force that will collide generation by underframe longitudinal member or decomposition of crossbeam actv. and transmission, thereby avoids the crew module position to deform.General body structure is to transmit decomposing force by the longitudinal and cross beam that independent design is welded on the vehicle body.Traditional base arrangement design is that the base plate relevant position arranges that two longerons are connected with front side member, impact force from front side member be delivered on the underframe longitudinal member and threshold on.Most designs can be decomposed into the impact force in the place ahead four paths and transmit.If there is not fine consideration impact force to be delivered on the threshold smoothly on the structure design, the power that overwhelming majority longeron transmits can only be by the underframe longitudinal member transmission, can't reduce transmission power, may cause base cross members to produce distortion and folding, the occupant is caused certain injury risk.Because this local thing of arranging of middle passage is many, should consider the arrangement space of back row's leg room, parking brake, shift handle etc., also to consider the layout of bottom freeing pipe.So it is particularly important that the design of middle channel architecture seems.
The utility model content
The purpose of this utility model provides a kind of middle channel architecture of auto body base plate, problem such as too concentrates to solve in the middle of the present back seat the less and power of transmitting when before bumping in occupant leg space.
The technical scheme that its technical matters that solves the utility model adopts is: the middle channel architecture that a kind of auto body base plate is provided, it comprise in channel body and with described in integrated two side flangings of channel body, be axially arranged with first cavity in described in the middle of the channel body, described two side flangings axially are provided with reinforced rib respectively, and the rear portion of described middle channel body forms the cross section and is trapezoidal level and smooth transition face.
Described reinforced rib is second cavity.
The cross section of described second cavity is trapezoidal.
The cross section of described first cavity is trapezoidal.
The invention has the beneficial effects as follows: with respect to prior art, the enclosed beam of the both sides of channel architecture has disperseed a part of power in the utility model, and this has just guaranteed well that the floor keeps balance when power is transmitted, and integral body is transmitted backward.In addition, in forward and backward seat crossbeam and the middle passage behind brace panel, the middle passage brace panel constitute two beams together and supporting threshold.Improved the side impact performance.Because this middle passage has increased the faying surface with the floor, and the structure of enclosed beam is made in the place that will overlap.In addition, middle channel rear portion is made level and smooth transition face, also solves the narrow problem of back row's middle passenger leg room.The bang path of power, raising side impact performance when bumping before passage has increased in being somebody's turn to do.Improved occupant's traveling comfort.
Description of drawings
Fig. 1 is the block diagram of the middle channel architecture of the utility model auto body base plate.
Fig. 2 is the enlarged drawing in the vertical section of midway location of the middle channel architecture of the utility model auto body base plate.
Fig. 3 is the middle channel architecture of the utility model auto body base plate and the longitudinal section of preceding floor assembly.
The specific embodiment
With the specific embodiment the utility model is further elaborated with reference to the accompanying drawings below.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the middle channel architecture of the auto body base plate that the utility model provides, should in channel architecture 10 comprise in channel body and with this in integrated two side flangings of channel body, should be axially arranged with first cavity 12 in the middle of the middle channel body, this two side flanging axially is provided with reinforced rib respectively, in the present embodiment, this reinforced rib is the second less cavity 14.Formation cross section in the rear portion of channel body is trapezoidal level and smooth transition face 16 in being somebody's turn to do.The cross section of first cavity 12 that this centre is bigger roughly is trapezoidal.It is trapezoidal that the cross section of second cavity 14 that this is less also roughly is.This second less cavity 14 has starting section and cross section, back, and this starting section is connected with front side member, and back cross section is connected with the floor, back.Should in channel architecture 10 dual-sides increased faying surface with preceding floor 20, and the place that will overlap (promptly two less second cavity 14) makes the structure of enclosed beam.Should middle channel architecture 10 form the structure of two cavitys 17,18 with the formation enclosed beam with this 20 welding backs, preceding floor.
Please refer to Fig. 3, before high speed, bump when taking place, power along front side member and a left side, preceding floor/right vertical beam tie-beam body to middle path 10 transmission.The enclosed beam of wherein middle passage both sides has disperseed a part of power, and this has just guaranteed well that the floor keeps balance when power is transmitted, and integral body is transmitted backward.In addition, in forward and backward seat crossbeam and the middle passage behind brace panel, the middle passage brace panel constitute two beams together and supporting threshold, improved the side impact performance.Because this middle passage has increased the faying surface with the floor, and the structure of enclosed beam is made in the place that will overlap.In addition, middle channel rear portion is made level and smooth transition face, solves the narrow problem of back row's middle passenger leg room.Middle passage has increased the faying surface with the floor, and the structure of enclosed beam is made in the place that will overlap.The bang path of power, raising side impact performance when bumping before having increased.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
