Description
Technical field
This utility model relates to car lamp device, and specifically, this utility model relates to a kind of light type converting means shading
Plate buffer rubber gasket.
Background technology
Automobile lighting lamp is necessary for the illuminating effect that the automobile in travelling provides optimal.But, in actual road
Under the traffic environment of road, when two automobile meetings travelled in opposite directions, the high light of headlamp can cause dazzling the eyes of driver
And have the danger that vehicle accident occurs.
To this, the settling mode currently mainly taked is that the use of the headlamp etc. to automobile carries out light type conversion.
The different situation used according to light type conversion and requirement, use different headlamps.On the other hand, the biggest portion
Separating vehicles headlamp all uses combined lamp, will form a whole use by the light fixture such as headlamp, front directional.
Although, as it has been described above, the assembling lamp used that the light fixture such as headlamp, front directional is formed a whole
Have readily accessible, assemble, the advantage such as cleaning, but there is also lamp installation space and limit the problem caused.For
This, it is proposed that the conversion integration of the light type of headlamp, the farthest, low beam use same light source, lead to when driving
Overregulate internal structure to switch the functional requirement of light type conversion.
But, at the described combined lamp light fixture such as headlamp, front directional being formed a whole and using
Occasion, once light type mapping function is the best or loses efficacy, and by the illumination functions of infringement light type conversion, thus easily causes
Safety and vehicle accident.As can be seen here, in car lighting lamp, light type conversion is particularly important, and it will directly affect
Safety to running car.
To this end, existing people researchs and develops multiple light type converting means.
But, the problem that the need that the light type converting means of conventional car headlamp exists improve is: light type changed
Journey easily occurs clamping stagnation；Moment of torsion output instability, noise is big.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is: provide a kind of light type converting means shading
Plate buffer rubber gasket, according to light type converting means used in sunshade board buffer rubber gasket described in the utility model, light type becomes
During change, light type is stable, it is not easy to clamping stagnation occur, and its compact conformation is simple, reduces noise.
The technical scheme of a kind of light type converting means used in sunshade board buffer rubber gasket of the present utility model is as follows:
A kind of light type converting means used in sunshade board buffer rubber gasket, is arranged between movable light shield plate and clamper,
Described movable light shield plate can be under Spur Gear Driving mechanism drives, for fulcrum at car headlamp bottom it
Front to spinning upside down, carry out with light type conversion match shading switching,
It is characterized in that,
Movable light shield plate 5 is provided above buffer rubber gasket, described buffer rubber gasket bag near clamper 6 side
Including rubber ring main part and the buffer edge part of nearly clamper 6 setting, described rubber ring main part is cylindricality,
For the location of movable light shield plate, described buffer edge part is the thin rubber limit of a sucker shape.
Described rubber ring main part runs through movable light shield plate 5 and arranges, and rubber blanket itself is an elastic component, fixed
Plane is dependent on the rubber ring main part of centre, the bounce being designed to absorption rubber of buffer edge, can make screening
Tabula rasa is an existing buffering before contacting with clamper (fixing dark slide), thus reduces noise and avoid light type to tremble
Dynamic.
According to a kind of light type converting means used in sunshade board buffer rubber gasket described in the utility model, it is characterised in that:
Described buffer edge part is radially slotted, a thin rubber limit for sucker shape.
According to a kind of light type converting means used in sunshade board buffer rubber gasket described in the utility model, it is characterised in that:
Described movable light shield plate is disposed in proximity to two ends above clamper 6 side.
According to a kind of electric motor type light type conversion driving means described in the utility model, housing 1 is installing rotary gear shaft
Sub-unit one end offside is provided with the torsion spring driving movable light shield plate 5, the installation center of described torsion spring and rotary gear shaft
The center of rotation of sub-unit is distance away, and the most described torsion spring is the center of rotation with rotary gear shaft sub-unit
Non-coaxial installation.
Different from general torsion spring design, it is non-coaxial mounting design at this.Purpose is to make torsion spring at full row
In journey, keep the most constant torque value, it is to avoid the clamping stagnation in light type change procedure.It addition, at movable light shield plate
During rotation, the point of application of torsion spring can slide on the straight flange of torsion spring, thereby ensures that torsion spring is the most permanent
Fixed torque value.
When headlamp is realized to low-beam function by high beam function, described movable light shield plate 5 is by spring force certainly
Moving and be returned to initial position, headlamp realizes low-beam function.Reduction can be played because of movable light shield plate 5 contact folder simultaneously
The effect of the noise that holder 6 causes.
According to light type converting means used in sunshade board buffer rubber gasket described in the utility model, light in light type change procedure
Type is stable, it is not easy to clamping stagnation occur, and its compact conformation is simple, reduces noise.
