Description
Technical field
The present invention relates to car lamp device, in particular it relates to a kind of electric motor type light type conversion driving means is used
Rotary gear shaft sub-unit structure and application thereof.
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
There is 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.
Such as, the Chinese utility model patent of Application No. " 200720129230.3 ", disclose a kind of light type
Converting means, it is characterised in that: described fixing catch is located at the leading edge of reflector body, described adjusting apparatus bag
Containing electromagnetic valve (light type converting means) and active blade, described electromagnetic valve (light type converting means) is provided with
Motion bar, uses and described active blade connects, and described active blade is to fix with described with pin connected assembly
Catch connects, in order to by described pin connected assembly as the rotary shaft of active blade, described active blade is to prolong
Stretch and have and the linking arm of the described perpendicular shape of active blade body, use and described electromagnetic valve (light type conversion dress
Put) motion bar connect.
But, according to the light type converting means of described utility model patent, its modular construction is relative complex, and its
Main purpose is to protect minimizing and the temperature rise amplitude of power consumption, it is difficult to reach to switch flexible, the group of simple in construction
Box-like Functional Requirement.
It addition, during driver drives vehicle, there will be the situation of meeting and climb and fall unavoidably.Particularly automobile is at row at night
When sailing, when the car bulb gone in the same direction and climb and fall, the reflection light on road surface can affect the vision of driver, if too
Will result in by force driver and do not see road ahead, so needing driver to switch the light type of automobile in time, if
Switching is not in time, it is possible to cause vehicle accident.Therefore, modern vehicle is widely used light type mapping device and realizes vapour
The light type conversion of car controls, and electromagnetic actuator is widely used in light type mapping device.Utilize electromagnetic actuator
In electric magnet absorption and the action of resilience can realize the switching of light type, and its action is the most reliable.
But, in actual applications, can send out during due to the electromagnetic actuation in existing electromagnetic actuator and release
Go out bigger collision noise, thus attract the complaint of some users.The most increasingly emphasizing user's comfort
Overall situation under, noise when reducing electromagnetic actuator work just seems and is extremely necessary.Additionally, electric magnet
Stronger vibrations can be produced when adhesive and release, the most easily cause light shape to shake, and this vibrations also can cause
Connect faults such as loosening, affect the reliability of light type mapping device.
It addition, number of patent application be " 201410226360.3 ", invention entitled " a kind of car headlamp
Light type converting means " disclose a kind of light type converting means being mainly used in vehicle xenon headlamp, use shearing
Dynamic iron core type electromagnetic valve (light type conversion driving means), and include: the clamper being fixed on reflecting mirror, it is special
Levying and be, clamper is fixed with electromagnet, described electromagnet is connected with connecting bushing by axostylus axostyle, institute
Stating connecting bushing to match with movable light shield plate, it is freely rotatable that described movable light shield plate matches by around rotary shaft
Change its angle.
But, according to the light type converting means of above-mentioned car headlamp, movable light shield plate turns around one side shaft fulcrum
Dynamic, changed by the angle changing movable light shield plate, cause the change of shaded effect, the angle of its movable light shield plate
The change at the shading position that change brings receives restriction, affects light type transform effect；
It addition, according to the light type converting means of above-mentioned car headlamp, the link stopper of its most simple spacing one end
Structure, only serves position-limiting action, and without noise reduction, therefore operating noise is big.
As it is shown in figure 1, use the work of the system of shearing dynamic iron core type electromagnetic valve (light type converting means) in the past
Make principle as follows:
When driver needs to use car light road function, press light type conversion driving lever, BCM (the i.e. light of hardware and software platform
Type conversion electromagnetic valve module) can power to electromagnetic valve (light type converting means), produce electromagnetic force after coil electricity,
Iron core is moved, and linkage drives dark slide to move down, it is achieved road function, automatic by spring force after power-off
Electromagnetic valve is returned to initial position.In actual applications, due to the electromagnetic actuation in existing electromagnetic actuator
Bigger collision noise can be sent during with release, thus also attract the complaint of some users.
Under the overall situation the most increasingly emphasizing user's comfort, reduce when electromagnetic actuator works
Noise just seems and is extremely necessary.Additionally, electric magnet can produce stronger vibrations when adhesive and release, also hold
Easily causing light shape to shake, and this vibrations also can cause the faults such as connection loosens, affect light type mapping device can
By property.
Therefore, the light type converting means of conventional car headlamp there is the problem that in light type change procedure easily
Clamping stagnation occurs；Moment of torsion output instability, cost is high, and noise is big, and compatibility is the best.

Output and reduction noise.
Further, since overcome tradition light type converting means to be mainly used in the light type converter unit of xenon headlight, this
Invention is applicable to the occasion such as xenon headlight and Halogen light, promotes it compatible.
