The certain length (d1) in corresponding border of two expansion adhesive tape, in said first direction, described first expansion adhesive tape and described the
Three expansion adhesive tape separate certain interval (d2, d3) with described second expansion adhesive tape.
Further, described first direction is perpendicular to described second direction.
Further, described interior panel beating has two horizontal plate faces and a vertical plate face, described two horizontal plate faces and described perpendicular
Straight panel face has been respectively formed on perforate, and described first expands adhesive tape and the described 3rd expands adhesive tape by opening in described two horizontal plate faces
Hole is injected in described cavity, and described second expands adhesive tape is injected in described cavity by the perforate in described vertical plate face.
Further, described first direction is the length direction of automobile, and described second direction is the width of automobile.
Further, described first expands adhesive tape, the second expansion adhesive tape and the 3rd expansion adhesive tape uniform thickness.
Further, described first expansion adhesive tape and the 3rd expansion adhesive tape protrude from described second in this second direction
The length (d1) expanding adhesive tape is 5mm.
Further, described first expands adhesive tape and the 3rd expansion adhesive tape with described second expansion adhesive tape in described first party
Gap (d2, d3) upwards is 5mm.
By the partition-type structures of vehicle body b post lower cavity of the present utility model, can tight closure vehicle body b post lower cavity
, and wind-dryness can be separated, and then car load nvh performance can be improved.
Brief description
Fig. 1 is the schematic diagram of the partition-type structures of vehicle body b post lower cavity of the utility model one embodiment.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is further elaborated.It should be appreciated that this place is retouched
The specific embodiment stated only in order to explain the utility model, is not used to limit the utility model.
Fig. 1 is the schematic diagram of the partition-type structures of vehicle body b post lower cavity of the utility model one embodiment.Under vehicle body b post
The partition-type structures of portion's cavity include interior panel beating 4 and outer panel beating 5, and both pass through to be welded to connect, and form a cavity between the two, described
Interior panel beating 4 has two horizontal plate faces 41 and a vertical plate face 42, and this two horizontal plate face 41 and this vertical plate face 42 have been respectively formed on
Perforate, these perforates are formed in other process of automobile.Tapping in vertical plate face 42 is injected with through adhesive supplier
The the second expansion adhesive tape 2 extending along a first direction, the tapping in two horizontal plate faces 41 is injected with along one the through adhesive supplier
The first expansion adhesive tape 1 and the 3rd expansion adhesive tape 3 that two directions extend, described first expands adhesive tape 1, described second expansion adhesive tape 2
With the described 3rd expansion adhesive tape 3, preferably there is identical thickness.Described first direction perpendicular to described second direction, in this reality
Apply in example, described first direction is the length direction of automobile, described second direction is the width of automobile.In described second party
Upwards, the border of the close described second expansion adhesive tape 2 of described first expansion adhesive tape 1 and described 3rd expansion adhesive tape 3 protrudes from
Certain length d1 in corresponding border of described second expansion adhesive tape 2, in said first direction, described first expands adhesive tape 1 He
Described 3rd expansion adhesive tape 3 is spaced one from certain interval d2 and d3 with described second expansion adhesive tape 2, implements in the utility model one
In example, consider and expand the frothing percentage (being 6-12 times in the present embodiment) of adhesive tape and the size of cavity, the first expansion adhesive tape 1
Length d1 protruding from the second expansion adhesive tape 2 in a second direction with the 3rd expansion adhesive tape 3 is set to 5mm, the first expansion adhesive tape 1
Expand adhesive tape 2 gap d 2 in a first direction with the 3rd expansion adhesive tape 3 with second and d3 is disposed as 5mm.By between setting
Gap d1 and d2, can prevent from expanding adhesive tape mutual generation planted agent's force phenomenon in foaming process, local shrinkage cavity and then closure
Not tight.In an embodiment of the present utility model, expand adhesive tape after painting electrophoresis baking foaming, just fill up interior panel beating
The cavity being formed between 4 and outer panel beating, thus the hot-tempered bang path made an uproar with wind in road can be separated, improve the nvh effect of car load；And
And, because first expands adhesive tape 1, second expansion adhesive tape 2 and the 3rd expansion adhesive tape 3 by perforate injection existing on plates of automobile
In cavity between panel beating need not extra openings or reaming on panel beating, simplify the utility model vehicle body b post lower cavity
Partition-type structures manufacturing procedure；Further, the plugging material due to adopting expands adhesive tape for heat, therefore compared to whole
By the way of the plugging material cut-off that cannot expand, the weight of partition-type structures can be substantially reduced.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in the utility model
Protection domain within.
