Cavity in use；The white body position bottom plate Chong Liang of certain OEM needs to be filled at present, but this position cavity can not set up peace
Hole (but with installation bolt) is filled, cavity inside space is again larger, and patch type cavity filling material can not to this large volume cavity
It is filled up completely.In conclusion needing to design insertion installing type height filling on the inside of the bottom plate weight beam that one can use bolt installation
Foaming material.
Summary of the invention
The utility model provides a kind of car floor weight beam inside insertion high filling-foam material of installing type.This filling material cost
Low, expansion ratio is high.Packing material can combine closely after expanding with white body steel plate.Meanwhile fixing sleeve is in conjunction with steel plate
Degree is high, is not easy to generate filler material displacement or obscission in foaming process, solves existing automobile packing material big empty
Chamber and when can not set up mounting hole, also may be mounted on steel plate and completes to fill to cavity.
To achieve the above object, the utility model uses following technical scheme:
A kind of car floor weight beam inside insertion high filling-foam material of installing type, including frame board, EVA foaming layer, it is described
Frame board and car floor weight beam cavity similar shape are leaned in the one circle EVA foaming layer of outer rim cladding of frame board in the lower part of frame board
Nearly skeleton outer rim integrally produces a fixing sleeve, and the fixing sleeve is avoided in EVA foaming layer, which covers in car floor weight beam cavity
Bolt on to fixed skeleton.
Moreover, being formed with two anti-pivoted arms along outer rim on skeleton.The length of anti-pivoted arm is 30~50mm, anti-pivoted arm width 8
Two 110~120mm of anti-pivoted arm spacing of~10mm, 10~13mm of anti-pivoted arm thickness.
Moreover, the fixing sleeve appearance is square column type, the inner hole of upper lower open mouth, fixing sleeve can block to be up-narrow and down-wide
The hole of tight bolt.
Moreover, being formed with a circle reinforcing rib, the inner edge of reinforcing rib and EVA foaming layer on the inner edge frame board of EVA foaming layer
Contact.
Moreover, skeleton plate thickness 1.5~3mm, EVA foaming layer with a thickness of 4~6mm.
Moreover, frame board is connect with EVA foaming layer by two-shot process.
The utility model has the beneficial effects that
1, it is inserted into the high filling-foam material of installing type on the inside of car floor weight beam provided by the utility model, has combined bone
Frame fills the advantages of material, and it is also mountable when mounting hole itself to have the characteristics that the big cavity of filling, cavity steel plate can not be opened, with compared with
Big market potential.
2, compound upper plug-in type square hole skeleton structure in the utility model EVA foaming layer, so that install convenient, is not easy to take off
It falls.
3, the utility model has devised anti-pivoted arm structure simultaneously, allows part during installation and supports when passing through electrophoresis liquid
Imperial external force acts on it and is subjected to displacement.
4, car floor weight beam internal cavity is passing through 20-30min, and after 150-210 DEG C of high-temperature baking, EVA foaming layer is carried out
It is sticked to after foaming on the inside of bottom plate weight beam on steel plate, is closely combined into one, cavity passage barrier is effectively reached hermetically sealed,
So as to improve the purpose of interior sound insulation vibration and noise reducing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the inner hole structure schematic diagram of fixing sleeve；
Fig. 3 is the utility model scheme of installation in bottom plate weight beam cavity.
Specific embodiment
Below in conjunction with attached drawing, the technical solution in the utility model is clearly and completely described, the embodiment
Only the utility model preferred embodiment, is not all of embodiment.
It is inserted into the high filling-foam material of installing type on the inside of a kind of car floor weight beam, including frame board 5, EVA foaming layer 1, anti-
Pivoted arm 2 and fixing sleeve 4, the frame board and car floor weight beam cavity similar shape, in the one circle EVA foaming of outer rim cladding of frame board
Layer, 4~6mm of thickness of EVA foaming layer are formed with a circle reinforcing rib 3, reinforcing rib and EVA on the inner edge frame board of EVA foaming layer
The inner edge of foaming layer contacts, and a fixing sleeve is integrally produced on the frame board of EVA foaming layer cladding, it is solid that EVA foaming layer avoids this
Fixed set, the fixing sleeve appearance are square column type, and upper lower open mouth, the inner hole 6 of fixing sleeve is up-narrow and down-wide hole, the fixing sleeve set
To fixed skeleton on the bolt 8 of car floor weight beam cavity 7.
Skeleton is rotated by external impacts in order to prevent, is formed with two anti-pivoted arms along outer rim on skeleton, the two anti-pivoted arm
Length be 30~50mm.8~10mm of anti-pivoted arm width, 10~13mm of anti-pivoted arm thickness.
By transparency height, the strong organic glass of toughness is molded for frame board and fixing sleeve.Frame board and EVA foamed board are logical
Two-shot process is crossed to connect together.This foaming material is larger suitable for cavity and can not open the white body internal cavity of mounting hole,
And OEM cooperation welding installation bolt in cavity is needed, it can save in this way expense and the time of modification mold, simple easily behaviour
Make.
The manufacturing method of the utility model are as follows:
Firstly, resin and other raw mixtures are kneaded, squeeze out, are granulated, obtain for body of a motor car cavity
The particle of EVA foaming layer.Organic glass (PMMA) is molded by the frame board with fixing sleeve by injection molding machine again.Finally again
EVA expanded beads and frame board organic glass (PMMA) are subjected to injection molding by injection molding machine, so that EVA foaming layer and having
The frame board secondary injection molding of fixing sleeve.
The foaming material of injection molding is inserted directly into the installation bolt of bottom plate weight beam, so that automobile cavity packing material is steady
Fixed installation is on the steel plate.It foams, is completely filled in cavity cross section through the EVA foaming layer of overbaking workshop, by automobile bottom
The cavity truncation of plate weight beam is that several areolas realize the target for reducing noise.And without difficulty after the foaming of automobile cavity packing material
Smelling, good with vehicle body steel plate viscosity, injection mold is simple, and die cost is lower, is greatly saved manufacturing cost.
