Description
Technical field
This utility model belongs to automotive lighting components technical field and in particular to a kind of light modulation screw arbor assembly and its sealing connect
Access node structure.
Background technology
Automobile lamp is the important leverage of safe driving, and the stability of car light and reliability are then by each assembling knot
Structure determines, wherein more special is the sealing of light modulation structure.In automobile front component, the sealing of light modulation structure
Property is to ensure that automobile front light shape is good, illumination is sufficient and the key factor of steady operation.
Car light sealing affects the actual effect of automotive lighting, if the sealing of light modulation structure and lamp body drain pan is not
Good, when rainwater weather, muddy road, lamp interior is easily intake, and causes to haze inside lamp body, and condensing water droplet draws
Play that the illuminance that sends of car light is greatly lowered, road lighting obscures, serious conditions may result in car light disabler, causes to drive a vehicle
Dangerous.
As shown in figure 1, the light modulation structure of routine generally includes umbrella shape light modulation screw (1a), sealing ring (2a), flat shim
(3a) with Flos Mume pad (4a), first sealing ring (2a) is inserted in the gear tray bottom that umbrella shape dims screw (1a)；Spiral shell will be dimmed again
Silk penetrates lamp body drain pan installing hole, the space thickness of installing hole thickness >=between sealing ring (2a) and flat shim (3a)；Then will
Flat shim (3a) is inserted in umbrella shape light modulation screw (1a) bottom；Quincuncial cushion piece (4a) is inserted in umbrella shape light modulation screw (1a) and presses the most at last
Dim at the draw-in groove of screw (1a) to umbrella shape；After Flos Mume pad (4a) sticks into draw-in groove, umbrella shape light modulation screw (1a) is formed tight
Gu effect, allow it cannot resilience.
In above-mentioned light modulation structure, what light fixture was sealed is only sealing ring (2a), this sealing ring (2a) position
It is in the gear cap bottom that umbrella shape dims screw (1a), specification is usually：External diameter 9mm × internal diameter 6mm × thickness 1.5mm, works as tune
When lamp body drain pan locked by light screw, sealing ring (2a) is clamped between gear cap and lamp body drain pan.Now, the sealing property of car light
Just by sealing ring (2a), the tight linear contact and drain pan between maintains.Sealing ring (2a) dimensional thickness specification is less, by prunus mume (sieb.) sieb.et zucc.
Flower pad (4a) screens ensures its compactness contacting with lamp body drain pan, and required precision is too high, and material requires error very little, pipe
Control risk is larger, and sealing ring (2a) thickness is too thin, after being used for multiple times, makes sealing ring (2a) and drain pan mutually produce a large amount of mills
Damage, so that light fixture water inlet risk is significantly increased, car light service life greatly reduces.
This light modulation structure requires very high, highest permission 0.1mm to the fit dimension of Flos Mume pad (4a) and umbrella shape screw
Error, if size is bigger than normal, Flos Mume pad (4a) cannot stick in umbrella shape screw draw-in groove, umbrella shape screw cannot be formed with
The fixation of effect, when umbrella shape screw carries out light modulation rotation, Flos Mume pad (4a) and flat shim (3a) are both possible to come off thus making
Light modulation structure is become thoroughly to lose efficacy, lamp assembly also therefore becomes scrap.As size is less than normal, Flos Mume pad (4a) can stick into umbrella
In shape light modulation screw (1a) draw-in groove, but can be excessively loosening, so still cannot ensure good sealing property, have into water wind
Danger.So, this light modulation structure requires very, to be unfavorable for mass production for the quality of fit between part.
