Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Such as Fig. 1-5, the utility model proposes a kind of skeleton seal for sedan B-post inner chamber, including skeleton 1, its
Upper end is provided with two liquid pass holes 11 for running through, and the cross section of liquid pass hole 11 is Long Circle；Skeleton 1 is provided with and sedan B-post inner chamber
Raised 19 for matching；Contiguous block 16 is connected with the lateral wall of skeleton 1, the side wall of the end of contiguous block 16 is provided with paired falling
Thorn claw 15；Foaming layer has been respectively and fixedly connected with the lateral wall of skeleton 1 and the madial wall of liquid pass hole 11；Some vacuum cavities 14, its
Side by side located at the inside of skeleton 1；Clamping foaming layer 4, its end to end outside for being wrapped in contiguous block 16.
The material of above-mentioned clamping foaming layer 4 and foaming layer can select EVA, and the material of skeleton 1 can select PA66.
The shape of skeleton 1 matches with the section of sedan B-post internal cavities.
Due in skeleton 1 and non-physical, but with the structure of vacuum cavity 14, when partial noise travels to skeleton 1, very
Absolutely empty chamber 14 is the propagation of cut-off noise, and the effective noise that reduces travels to in-car from the external world.
The top and bottom of above-mentioned contiguous block 16 are respectively equipped with a tank 18 through its side wall；The bottom of tank 18 and
The side wall of contiguous block 16 is provided with and connects into a positioning convex for straight-flanked ring 17；Above-mentioned clamping foaming layer 4 respectively with tank 18,
Contiguous block 16 and positioning convex 17 are affixed.Tank 18 coordinates positioning convex 17, consolidates the position of clamping foaming layer 4, Bu Hui
There is dislocation in expansion process even to come off, it is ensured that its sealing effectiveness.
The equidistant laid out in parallel in skeleton 1 of above-mentioned vacuum cavity 14, and vacuum cavity 14 longitudinal section area equation.
The vacuum cavity 14 of cloth causes that its effect is more uniform, increased blocking of the skeleton 1 to noise.
The upper end or lower end border of the lateral wall of above-mentioned skeleton 1 are provided with positioning along 12；Above-mentioned foaming layer includes outside foaming layer
2, its lateral wall and positioning respectively with skeleton 1 is affixed along 12.The middle part border of the side wall of above-mentioned liquid pass hole 11 is provided with interior convex
Play 13；Above-mentioned foaming layer includes inner side foaming layer 3, and it is affixed with the side wall of liquid pass hole 11 and interior positioning convex 13 respectively.Positioning edge
12 and interior positioning convex 13 positioning action is played to outside foaming layer 2 and inner side foaming layer 3 respectively, it is to avoid it is in expansion process
Generation dislocation even comes off, it is ensured that its sealing effectiveness.
Above-mentioned contiguous block 16 has two, and both are located at the same side of skeleton 1.Prevent the utility model from using process
In, rotation is produced, so as to influence its sealing.
When using, two hangnail claws 15 are inserted simultaneously in the hole on sedan B-post metal plate, fix the utility model.
Now, the part of clamping foaming layer 4 is stretched into the hole on B post metal plates.By after the high-temperature baking of Painting Shop electrophoresis operation, outward
Side foaming layer 2 expands, and fills the cavity in B posts；Inner side foaming layer 3 is expanded, and liquid pass hole 11 is blocked；Clamping foaming layer 4
Expansion, and the hole on B post metal plates and its peripheral cavity are filled up.Now, the cavity in B posts is completely filled, and thoroughly blocks
The propagation of noise.
The above-mentioned skeleton seal for sedan B-post inner chamber of the utility model, simple structure, sealing is comprehensive.This reality
With new after being heated, the cavity in sedan B-post can be blocked by outside foaming layer 2, blocked noise transmission, improved car
Interior comfortableness.Can be fully sealed for installing hole of the present utility model on sheet metal component by clamping foaming layer 4, reinforced
While, the integrality of the utility model sealing is further increased, ensure that and block noise path completely.By skeleton
Vacuum cavity 14 in 1, can prevent noise from being propagated by skeleton 1, enough further to produce blocking effect to noise.
Preferred embodiment of the present utility model is more than above are only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
