Simultaneously, 2 of rubber cushion blocks work in installation process, install the meaning that just loses its existence.When just installing, rubber cushion blocks 2 and glass cement 3 consistency of thickness, but rubber cushion blocks 2 is solid-state, glass cement 3 is emulsifiable paste shapes.Glass cement 3 can shrink in solidification process, and glass cement 3 one sides are held sheet metal 1, and one side is held windshield 4, has formed the tensile force f that imposes on windshield 4 thus
Draw, according to application force and the antagonistic force principle of power, 4 need of rubber cushion blocks 2 place's windshields bear pressure F
PressReach equilibrium of forces.So, windshield 4 just can be subjected to the effect of stress between rubber cushion blocks 2 and glass cement 3, and stress was brought out easily when automobile travelled on bad road, caused glass breakage.
Summary of the invention
The purpose of this invention is to provide a kind of novel automobile wind shield glass mounting structure, eliminate the stress that bear in windshield installation end place, reduce the risk that windshield breaks.
For achieving the above object, the present invention has adopted following technical scheme:
Automobile wind shield glass mounting structure of the present invention comprises sheet metal, glass cement, windshield and solubility cushion block.The lower surface of described windshield is captiveed joint with the upper surface of described sheet metal by described glass cement.Described solubility cushion block is mixed by water-soluble material and compacting forms, and meets can complete reaction to dissolve after water washes away.The lower surface of described windshield installation end is captiveed joint with the upper surface of described solubility cushion block, described glass cement is positioned at the side away from described windshield installation end of described solubility cushion block, the lower surface of described solubility cushion block and the upper surface of described sheet metal are fitted, and described solubility cushion block keeps solid-state in installation process.
Preferably, described solubility cushion block hardness is Shao A60, and described solubility cushion block is under current scour, and disintegration rate is not more than 1 minute, makes described solubility cushion block can reach enough intensity when mounted, and rapidly disappears when current scour.
Preferably, described solubility cushion block is made up of sodium bicarbonate and organic acid, and described organic acid is citric acid or tartaric acid.
Preferably, described solubility cushion block is made up of sodium bicarbonate and a kind of organic acid, and both blending ratios are according to both chemical equation proportionings in water, can react rapidly after making the solubility cushion block meet water, and the reacted aqueous system be neutrality.
Preferably, described solubility cushion block is captiveed joint with described windshield by double faced adhesive tape.
Preferably, described solubility cushion block some be positioned at the outside of described windshield under on its thickness direction.Help to reduce the mounting structure size of described windshield like this, increase the field range of described windshield.
After changing original rubber cushion blocks into the solubility cushion block, the solubility cushion block both can have been finished spacing function had been installed, can before dispatching from the factory, be disappeared by water-soluble solution again, can not make windshield be subjected to the effect of stress with glass cement, reduce the glass breakage risk of bringing out stress when windshield travels on bad road and causing.
