Abstract
The preceding floor of a kind of automobile body-in-white provided by the utility model, including left front floor, centre gangway and right preceding floor, are integrally formed as complete front floor of vehicle body board member.The utility model only needs a stamping procedure when manufacturing, and is the processing for completing the preceding floor of automobile body-in-white without other welding sequences.Production efficiency is so not only increased, the stock utilization of floor assembly, can reduce the exploitation of corresponding mould, fixture, cubing before also improving, and reach and shorten vehicle productive temp, shorten the construction cycle and reduce the purpose of development cost.
Description
Technical field
Automotive field is the utility model is related to, particularly a kind of preceding floor of automobile body-in-white.
Background technology
As shown in Fig. 2, the preceding floor of most of vehicles is all fraction block structure at present, wherein fraction block structure just necessarily wraps
The parts such as left front floor 1, right preceding floor 3 and centre gangway 2 are included, the number of parts for so needing to develop is with regard to more, at the same time
Welding sequence also can be relatively complicated, including left front floor assembly, it is right before the small assembly such as floor assembly, centre gangway assembly weldering
Connect, the welding of floor assembly before finally carrying out again, is welded and also needs to carry out the spot welding seal between part in welding process, application is also
Need to carry out weld seam sealing；Furthermore different parts just needs different moulds and cubing, different welding sequences just needs not
Same welding fixture, adds the productive temp of vehicle, adds construction cycle and the cost of vehicle.
Utility model content
The technical problem to be solved by the present invention is to provide one kind on the premise of proof strength and security, it can reduce
The amount of parts of preceding floor assembly, the welding sequence of floor assembly before reduction, and then improve the automobile body-in-white of production efficiency
Preceding floor.
To achieve these goals, the technical solution that the utility model is taken is：
The preceding floor of the automobile body-in-white, including left front floor, centre gangway and right preceding floor, be integrally formed for
Complete front floor of vehicle body board member.
The front floor of vehicle body board member also has the preceding ground prelaminar part extended forward at the centre gangway front end.
Ground prelaminar part front end tilts obliquely upward before described.
The raised portion in ground prelaminar part front end stage casing passes through arc with the preceding ground prelaminar part horizontal component junction before described
Shape face seamlessly transits.
It is additionally provided with the front floor of vehicle body board member from the raised portion in the preceding ground prelaminar part front end stage casing and extends to institute
State the reinforcing rib at front floor of vehicle body board member rear portion.
Using above-mentioned technical proposal, include the front floor of vehicle body board member on left front floor, centre gangway and right preceding floor three
It is integrally formed, when manufacture only needs a stamping procedure, is to complete the preceding floor of automobile body-in-white without other welding sequences
Processing.Production efficiency is so not only increased, the stock utilization of floor assembly before also improving, can reduce corresponding mould, folder
Tool, the exploitation of cubing, reach and shorten vehicle productive temp, shorten the construction cycle and reduce the purpose of development cost.
Preceding floor is anterior in front of centre gangway, and left front floor part and floor part before the right side can be prevented along centre gangway
The bending edge on both sides produces deformation, improves the transverse strength of front floor of vehicle body board member.Stick up obliquely upward preceding ground prelaminar part front end
Rise, can also improve the transverse strength of front floor of vehicle body board member.After reinforcing rib, the longitudinal strength of front floor of vehicle body board member
Get a promotion.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of automobile front floor in background technology.
Mark in figure for：
1. ground prelaminar part, 5. raised portions, 6. reinforcing ribs before left front floor, 2. centre gangways, 3. right preceding floors, 4..
Embodiment
Below against attached drawing, by the description of the embodiment, making to the utility model embodiment further detailed
Explanation, with help those skilled in the art to the present utility model design, technical solution have it is more complete, accurate and deeply
Understanding.
As shown in Figure 1, the utility model provides a kind of preceding floor of automobile body-in-white, including left front floor 1, centre gangway
2 and right preceding floor 3.Three is split structure in traditional structure, integral by being weldingly connected.First its structure is changed
Into left front floor 1, centre gangway 2 and right preceding 3 three of floor are integrally formed by stamping equipment, become complete front floor of vehicle body
Board member.
The front floor of vehicle body board member is also improved in structure, to ensure the intensity and safety on the preceding floor of automobile body-in-white
Property.2 length of centre gangway is shortened to be had before centre gangway 2 positioned at front floor of vehicle body board member middle and back, front floor of vehicle body board member
The preceding ground prelaminar part 4 extended forward at end, essentially a plane, equipped with some grooves, mounting hole.But the preceding ground prelaminar part 4
Front end tilts obliquely upward, and raised portion 5 in ground 4 stage casing of prelaminar part passes through with 4 horizontal component junction of preceding ground prelaminar part before it
Arcwall face seamlessly transits.This structure makes the transverse strength of front floor of vehicle body board member be improved.Arc surface prevents warping part
5 are divided to be damaged with horizontal component junction intensity.
The raised portion 5 that 4 front end stage casing of prelaminar part in the past is additionally provided with front floor of vehicle body board member extends to front floor of vehicle body
The reinforcing rib 6 at board member rear portion.Reinforcing rib 6 can lift the longitudinal strength of front floor of vehicle body board member.
The preceding floor of this automobile body-in-white reduce before floor assembly amount of parts, while reduce before floor assembly weldering
Process is connect, and keeps original feature not change, its intensity can also be guaranteed.Main engine plants' production work can also be reduced at the same time
Sequence, site area, reduce vehicle number of parts, reduce the investment of mould, fixture, cubing, reduce cost.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implement and from
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that the utility model methodology and technical solution carry out
Into, or it is not improved by the utility model design and technical solution directly apply to other occasions, the utility model protect
Within the scope of shield.
