Abstract
The invention provides a passenger-car double floor based on modularized assembly and a mounting method thereof. The double floor is characterized by comprising an upper-layer floor, a lower-layer floor and a floor support arranged between the two layer floors, wherein a hollow cavity capable of placing parts, wires, and the like is formed between the two layers of floors to effectively save the in-car space. The mounting method comprises the following steps: a, mounting the floor support on the lower-layer floor; b, mounting the parts on the lower-layer floor; c, assembling the lower-layer floor, the mounted parts and the upper-layer floor into a whole; and d, mounting the assembled upper-layer floor, the lower-layer floor and the internal parts on a frame. The passenger-car double floor based on modularized assembly and the mounting method thereof adopt a layered structure of the upper-layer floor and the lower-layer floor, can optimize the whole car arrangement, improve the in-car space, enhance the whole car strength, facilitate the mounting modularization and systematization and improve the mounting efficiency.
Description
Technical field
The invention belongs to manned vehicle manufacturing technology field, specially refer to a kind of manned vehicle floor and assembly method thereof.
Background technology
Present engine behind front wheel forerunner, the manned vehicle of self-supporting body, the design form of single layer structure is all adopted on its floor, its individual layer floor can only be at the lower disposed fuel tank, pipeline, parts such as a spot of wire harness and part chassis member, therefore have in front deck and instrument carrier panel, arrange a large amount of parts, make in front deck and the instrument carrier panel quite compact, there are following several deficiencies in the car load that assembles this kind individual layer floor: 1, its underfloor numerous parts can only progressively be installed on the general assembly main line, can't modularization install, production efficiency is low, and cause general assembly main line station more, main line is longer, thereby causes workshop building to enlarge, and productive temp descends; 2, the parts of front deck internal placement are very many, and complicated, as storage battery, safety box, ABS etc., cause front deck to be arranged and are quite full, and cause the space of script ventilation and heat occupied, are unfavorable for engine radiating, influence car load temperature field flow field performance; 3, a lot of parts are arranged in instrument carrier panel inside, as some appliance electronic components and wire harness etc., influence the aesthetic property of car load assembling, and can reduce the storage space at car load instrument carrier panel place; 4, the intensity of car load front and side is relatively poor.
Summary of the invention
First purpose of the present invention is to propose a kind of passenger-car double floor based on the modularization assembling, can modularization assembled portion parts between the double floor, not only can improve the production efficiency of car load assembling, can also increase the car load space, double floor helps strengthening the intensity of positive and construction profile to a certain extent simultaneously.
Passenger-car double floor key based on modularization assembling of the present invention is that described floor is made up of upper and lower two-layer floor, is provided with floor stand between the two-layer floor.Form cavity between the two-layer floor, can settle parts and wire harness etc., effectively save interior space.
At least be provided with two floor stand that become cross layout between the described two-layer floor, can effectively strengthen the intensity of automobile front and construction profile.
The cross section of described floor stand is a U-shaped, can be when guaranteeing floor stand intensity expendable weight, thereby alleviate complete vehicle weight.
Described upper and lower two-layer floor is fixed by bolt and/or welding manner and floor stand, preferably adopt the welding of lower floor and floor stand, upper floor and floor stand are utilized the mode of bolt, so not only connect firm, and easy to assembly, help enhancing productivity.
Described upper strata and/or lower floor are provided with the lid that can open and close, to make things convenient for the work such as parts maintenance in later stage.
Second purpose of the present invention is the assembly method that proposes above-mentioned passenger-car double floor based on the modularization assembling, and this method key is to comprise following steps:
A, floor stand is assemblied on the lower floor;
B, parts are assemblied on the lower floor;
C, lower floor is assembled into one together with parts that assemble and upper floor;
D, the upper and lower layer floor and the in-to-in parts thereof that will assemble are installed on the vehicle frame.
In the above-mentioned a step, floor stand is to be assemblied on the lower floor by the mode of welding; In the above-mentioned c step, floor stand and upper floor are utilized bolt, thereby lower floor is assembled into one together with parts that assemble and upper floor, mounting structure is firm like this, efficiency of assembling is high.
Passenger-car double floor based on the modularization assembling of the present invention, adopt the hierarchy of upper floor and lower floor, between the two, form cavity, be used for arranging parts, not only can optimize car load arranges, improves interior space, strengthens car load intensity, increases safety, the floor of integral type can be improved aerodynamics simultaneously, reduces air resistance, and then reduces automobile fuel consumption.
The assembly method of the passenger-car double floor based on modularization assembling of the present invention, help the modularization and the systematization of assembling, improve efficiency of assembling, simultaneously can also realize producing in the mode that the branch wiring is set in general assembly main line collateral branch, reduce main line length, reduce and produce investment, improve productive temp.
