Abstract
To provide a floor panel of a vehicle body capable of ensuring maintenance property of accessory equipment installed under the floor and rigidity of the vehicle body in a high-dimensionally compatible manner. In this floor panel (a rear floor panel 1) of the vehicle body provided with an inspection port 4 for accessing the accessory equipment installed under the floor, a cross member extending in the direction of width of the vehicle body is divided into parts, a part of it is constituted of another member (a center cross member 8) capable of being repeatedly attached and detached, and the part composed of the above member is provided at a position where it crosses above the inspection port.
Description
Technical field
The present invention relates to a kind of base plate of car body, specifically, relate to have the base plate of the car body of access hole, it is used for maintenance person near the attendant equipments such as for example Fuel Tank under the base plate that is set at railway carriage.
Background technology
Though the Fuel Tank of automobile is provided under the base plate of railway carriages such as below of back seat, but, in order to ensure the maintaining performance that is set at attendant equipment equipment such as valve type on the Fuel Tank and pump, sometimes access hole is arranged on the base plate of car body, closes this access hole with the cap seal of detachable.
On the other hand; for restraining vehicle body distortion and vibration; and when side collision, protect operator's compartment to avoid the purpose of impact; on the base plate of car body, be provided with the strengthening part (crossbeam) (please refer to patent documentation 1: Japanese patent gazette spy opens 2001-247058 number) that extends along the width over sides of car body direction now.
Yet, when crossbeam being set in order to ensure the needed rigidity of base plate, if make the position of crossbeam preferential, so, the equipment under the base plate of railway carriage of being set at Fuel Tank etc. serves as that the position of the access hole of maintenance object just is restricted, and the position of the shape of Fuel Tank or attendant equipment equipment is limited in this crossbeam position.And in contrast, if make the position of access hole preferential, so, the position of crossbeam just is restricted, thereby is difficult to increase actv. intensity.That is, guarantee to be set at the maintenance of the equipment under the base plate of railway carriage and guarantee rigidity of vehicle body these two is difficult to simultaneously accomplished by suitably disposing crossbeam by suitably disposing access hole.
Summary of the invention
The present invention is the scheme that proposes in order to solve problem of the prior art as described above, its main purpose is, a kind of base plate of such car body is provided, and the maintenance and the rigidity of vehicle body that make Fuel Tank for example etc. be set at the attendant equipment under the base plate of railway carriage can be guaranteed simultaneously well.
In order to realize above-mentioned purpose, the base plate of car body of the present invention (back base plate 1) has access hole 4, described access hole 4 is used for maintenance person near the attendant equipment under the base plate that is set at railway carriage, the base plate of described car body is characterised in that, the crossbeam that the Width along car body of the base plate of car body extends is cut apart, and with the part in the crossbeam (centre cross member 8) but constitute by the individual components of repeated disassembled and assembled, the part that is made of above-mentioned individual components is set on the position across the top of above-mentioned access hole.
Structure according to the base plate of car body of the present invention, because can be on across the position above the access hole with beam erection, so, on the suitable position of the deformation pattern in the time of not only crossbeam can being arranged on the side surface of considering base plate and being subjected to colliding, and, can be when the attendant equipment under the base plate that is set at railway carriage be overhauled, the part across the top of access hole in the crossbeam is unloaded, so, can not hinder upkeep operation.Therefore, aspect improving base plate and being set at the degree of freedom of the design of plant under the base plate of railway carriage, can obtain effect preferably.
Description of drawings
Fig. 1 is the overall perspective view of back of the present invention base plate.
Fig. 2 is the exploded perspective view of main portion of the periphery of expression access hole.
The specific embodiment
With reference to the accompanying drawings, the present invention is described in detail.
Shown in Figure 1 is is suitable for an example of back of the present invention base plate 1, and illustrative here is the structure that is applicable to from the back seat installation portion 2 of rear cabin to the part of the spare tyre accommodation section 3 of baggage container.
After this base plate 1 forms by steel plate is carried out punch forming, has only represented its part among the figure.In order to try hard to guarantee needed rigidity, what back base plate 1 adopted is spatial structure, that is, and and in the convex-concave shape that has formed respectively on the overall width direction and on the fore-and-aft direction based on reinforced rib.
Under the base plate of railway carriage, be provided with Fuel Tank, as depicted in figs. 1 and 2, on the approximate centre position of in the birds-eye view of back base plate 1, being seen, be provided with the access hole 4 of the attendant equipment installation portion (not shown) that is used for the approaching above-mentioned Fuel Tank of maintenance person.This access hole 4 is covered with by lid 5 usually, and described lid 5 usefulness bolt B 1 are fixing, so that can carry out repeated disassembled and assembled.
The purpose of the car body distortion when realizing that suppressing vehicle body side is collided on the suitable position of the upper surface of back base plate 1, is provided with the crossbeam that extends along the width over sides of car body direction.This crossbeam is made of an offside crossbeam 6,7 and centre cross member 8, and described side crossbeam 6,7 is provided with in the mode of extending to the outside of car body from the left and right sides of access hole 4, and described centre cross member 8 is across above access hole 4.The medial extremity of two the side crossbeams 6,7 about being divided into and the two ends of centre cross member 8 are connected by bolt B 2.Thus, centre cross member 8 structurally becomes the parts that can carry out dismounting repeatedly.
The cross sectional shape of each crossbeam 6～8 forms trapezoidal; About the both ends of side crossbeam 6,7 be closed, be connected on the base plate 1 of back in modes such as welding and be formed the osed top cross section by being set at flange 9 on its lower edge.In addition, about side crossbeam 6,7 on the part that has root that regards to back base plate 1 on, connecting the child seat usefulness fixed link 10 that forms by the round bar shape material bending.
Like this, according to the structure of hull bottom plate of the present invention, owing to made the structure of setting up the centre cross member 8 of dismounting freely on across the position above the access hole 4, so, be set in maintenance when the attendant equipment under the base plate of railway carriage, as long as unload centre cross member 8.Therefore, not only guaranteed the rigidity of back base plate 1, can also guarantee that maintenance person can be from access hole 4 near the equipment under the base plate that is set at railway carriage.Therefore, the rigidity of the setting degree of freedom of the position of access hole 4 and back base plate 1 these two can be guaranteed well simultaneously.
Claims (1)
1. the base plate of a car body, it has access hole, and described access hole is used for maintenance person near the attendant equipment that is set under the cabin floor,
It is characterized in that: the crossbeam that the Width along car body of the base plate of car body extends is cut apart, and but the part of this crossbeam individual components by repeated disassembled and assembled constituted, the part that is made of above-mentioned individual components is set on the position across the top of above-mentioned access hole.
