Description
[technical field]
The present invention relates to a kind of auto body encapsulating method, particularly relate to a kind of auto body gusset Expansion sealing method.
[background technology]
Automobile is more and more important in the modern means of communication for us, and people are also more and more higher to the requirement of its each side, and wherein, the leak tightness and the The noise of automobile are subjected to common concern.Prior art below in conjunction with 1 pair of auto body side panel sealing of accompanying drawing method is made brief description: body side wall is owing to exist closed box strength beam structure, so there is the bypass cavity structure, when running at high speed, can produce High Speed Airflow Within at the gusset cavity, the gusset High Speed Airflow Within is the root that produces the hot-tempered and transfer car external noise of cavity wind, and suppressing that wind makes an uproar must blocking-up gusset cavity air-flow.In present side panel sealing method, be to fill compressed sponge or adopt the PU foaming in place at the gusset cavity, foaming by sponge expansion or PU fills up the cavity of gusset, and blocking-up gusset cavity air-flow plays the leak free effect.But the sealing property of this encapsulating method can not satisfy people's requirement, and noise reduction is very little.
A kind of technology of automobile sealed structure is disclosed among the Chinese patent CN200620072346.3, a kind of technology of automobile sealed doorframe is disclosed among the Chinese patent CN96208568.5, a kind of technology of carrier sealing arrangement is disclosed among the Chinese patent CN95209972.1, though above-mentioned patent all discloses different packing techniquies, all fail to solve the problem of present existence.
[summary of the invention]
Technical matters to be solved by this invention provides a kind of auto body gusset Expansion sealing method, its objective is the sealing property that strengthens gusset, sound insulation and noise reduction.
For solving the problems of the technologies described above, the technical solution used in the present invention is: place at least 5 place's noise insulation blocks at vehicle side, comprise noise insulation block under noise insulation block on the A post, the A post, B post noise insulation block, C post noise insulation block, rear wheel cover noise insulation block.Noise insulation block is installed on the top of side wall assembly front end on the A post, stop noise from machinery space, noise insulation block is installed on the bottom of side wall assembly front end under the A post, stop noise from the chassis, described noise insulation block is made up of four parts: both sides are plastic dam, middle edge position design plastic stent, filled with foaming material in the middle of plastic stent and the baffle plate, and plastic buckle is installed.
Particularly, have square hole on the body side wall assembly, with buckle form and body contact, noise insulation block and vehicle body sheet metal component cavity section keep the gap of 4～5mm to noise insulation block by square hole.
Compared with prior art, the present invention has following beneficial effect: adopt the high velocity air of technique scheme gusset cavity capable of blocking more than 85%, both can strengthen the sealing property of whole vehicle body, can play the effect of sound insulation and noise reduction again.Because the noise insulation block middle edge is a plastic stent, the expanded material materials are few, and are not only simple in structure, and save cost, and sealing is even, the sealing efficiency height, and the sound insulation and noise reduction effect is obvious.This scheme just is provided with noise insulation block in the side wall assembly part, and the workshop has good workability, and the efficient height is fit to produce in enormous quantities.
[description of drawings]
With reference to respective drawings, will become more clear in conjunction with preferred implementation other purposes of the present invention, details, feature and advantage, described embodiment only is exemplary introduction and unconfined intention, wherein:

Be labeled as among the figure: 1, noise insulation block 3, B post noise insulation block 4, C post noise insulation block 5, rear wheel cover noise insulation block 6, side wall assembly 7, baffle plate 8, support 9, expanded material 10, buckle 11, turbulence noise (dotted arrow) 12, pass-by noise (solid arrow) under noise insulation block 2, the A post on the A post
[specific embodiment]
With reference to gusset High Speed Airflow Within expressed among Fig. 1, can find out that noise source mainly is turbulence noise 11 and pass-by noise 12.Turbulence noise 11 mainly is because cavity is inhomogeneous, and the pipe resistance is big, and high velocity air and the friction of cavity obstacle form eddy current at cavity wall, produce the turbulence pneumatic noise; Turbulence air-flow itself also can cause sheet metal component resonance, produces cavity plate resonance noise.Pass-by noise 12 comprises that mainly motor noise, tire make an uproar etc.
With reference to Fig. 2 to Fig. 7, according to a preferred embodiment of the invention, placing 5 place's noise insulation blocks on the side wall assembly 6 altogether: noise insulation block 2, B post noise insulation block 3, C post noise insulation block 4, rear wheel cover noise insulation block 5 under noise insulation block 1, the A post on the A post.Each noise insulation block can both play the effect that stops turbulence noise 11; For stopping of pass-by noise 12: wherein noise insulation block 1 is installed on side wall assembly 6 upper front end on the A post, stop noise from machinery space, noise insulation block 2 is installed on that side wall assembly 6 front end bottoms, B post noise insulation block 3 are installed on side wall assembly 6 middle and lower parts, C post noise insulation block 4 is installed on to survey and encloses assembly 6 rear end lower under the A post, they mainly stop the noise from the chassis, rear wheel cover noise insulation block 5 is installed on side wall assembly 6 upper rear end, stops the noise from boot compartment.
According to the difference of gusset cavity cross section, the noise insulation block shape at each position also has nothing in common with each other, but all is made up of four parts: wherein both sides are plastic dam 7; Middle edge position design plastic stent 8; Plastic stent 8 and baffle plate 7 middle filled with foaming material 9; And installation plastic buckle 10.What wherein play a major role is expanded material 9, through after the coating baking, and foamed material 9 meeting foaming and intumescings, expansion rate is 600%, thereby fills up the whole cavity of gusset, plays the effect of sound insulation and noise reduction.Have square hole on the body side wall assembly 6, noise insulation block by square hole with plastic buckle 9 and body contact, accurate positioning, easy for installation; Noise insulation block and vehicle body sheet metal component cavity section keep the gap of 4～5mm, do not influence pre-processing, electrophoresis, painting technology.
Though in conjunction with specific embodiments the present invention is described in detail; but obviously the invention specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
