Description
Technical field
The present invention relates to car lamp device, in particular it relates to a kind of low-power DC Motor Drives device and application thereof。Described low-power DC Motor Drives device is for car light type conversion。
Background technology
Automobile lighting lamp is necessary for the illuminating effect that the automobile in traveling provides best。But, under actual road traffic environment, when two automobile meetings travelled in opposite directions, the high light of headlamp can cause dazzling the eyes of driver to have the danger of generation vehicle accident。
To this, the use that the settling mode currently mainly taked is 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, currently the majority vehicle head lamp all adopts combined lamp, forms a whole use by the light fixture such as headlamp, front directional。
Although, as it has been described above, the assembling lamp used that formed a whole by the light fixture such as headlamp, front directional has the advantages such as readily accessible, assembling, cleaning, but there is also the problem that the restriction of lamp installation space causes。It is proposed to this end that headlamp light type conversion integration, namely far, low beam use same light source, when driving by regulate internal structure switch light type conversion functional requirement。
But, in the occasion of the described combined lamp light fixture such as headlamp, front directional being formed a whole and using, once light type mapping function is not good or loses efficacy, will the illumination functions of infringement light type conversion, thus easily caused by safety and vehicle accident。As can be seen here, in car lighting lamp, light type conversion is particularly important, and it will directly influence the safety of running car。
For this, existing people researchs and develops multiple light type converting means。
Such as, application number is the Chinese utility model patent of " 200720129230.3 ", disclose a kind of light type converting means, it is characterized in that: described fixing catch is located at the leading edge of reflector body, described adjusting apparatus includes electromagnetic valve and active blade, described electromagnetic valve is provided with motion bar, with and described active blade connect, described active blade is to be connected with described fixing catch with pin connected assembly, in order to by the described pin connected assembly rotating shaft as active blade, described active blade is to be extended with and the linking arm of the described perpendicular shape of active blade body, with and the motion bar of described electromagnetic valve connect。
But, the light type converting means according to described utility model patent, its modular construction relative complex, and its main purpose is in that the protection minimizing of power consumption and temperature rise amplitude, it is difficult to reach switching flexibly, the combination type functional requirement of simple in construction。
It addition, during driver drives vehicle, there will be the situation of meeting and climb and fall unavoidably。Particularly automobile is when night running, 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 will result in driver too by force 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 widely uses light type mapping device and realizes the light type conversion control of automobile, and electromagnetic actuator is widely used in light type mapping device。The action utilizing the absorption of the electric magnet in electromagnetic actuator and resilience can realize the switching of light type, and its action is comparatively reliable。
But, in actual applications, bigger collision noise can be sent during due to the electromagnetic actuation in existing electromagnetic actuator and release, thus attracting the complaint of some users。Under the overall situation increasingly emphasizing user's comfort now, noise when reducing electromagnetic actuator work just seems and is extremely necessary。Additionally, electric magnet can produce stronger vibrations when adhesive and release, also shake easily caused by light shape, and this vibrations also can cause the faults such as connection loosens, and affects the reliability of light type mapping device。
Additionally, number of patent application is " 201410226360.3 ", denomination of invention discloses a kind of light type converting means being mainly used in vehicle xenon headlamp for " the light type converting means of a kind of car headlamp ", use shearing dynamic iron core type electromagnetic valve (light type conversion driving device), and include: the clamper being fixed on reflecting mirror, it is characterized in that, clamper is fixed with electromagnet, described electromagnet is connected with connecting bushing by axostylus axostyle, described connecting bushing matches with movable light shield plate, described movable light shield plate matches by its angle of freely rotatable change around rotating shaft。
But, light type converting means according to above-mentioned car headlamp, movable light shield plate is around one side shaft fulcrum, by changing the angle change of movable light shield plate, cause the change of shaded effect, the change at the shading position that the angle change of its movable light shield plate brings is restricted, and affects light type transform effect；
It addition, the light type converting means according to above-mentioned car headlamp, the stop structure of its spacing simply simple one end, only serving position-limiting action, without noise reduction, therefore operating noise is big。
As it is shown in figure 1, the operation principle of the system of the shearing dynamic iron core type electromagnetic valve of use is as follows in the past:
When driver needs to use car light road function, press light type conversion driving lever, BCM (i.e. the light type conversion electromagnetic valve module of hardware and software platform) can to solenoid valve, electromagnetic force is produced after coil electricity, iron core is moved, linkage drives dark slide to move down, it is achieved road function, automatically electromagnetic valve is returned to initial position by spring force after power-off。In actual applications, bigger collision noise can be sent during due to the electromagnetic actuation in existing electromagnetic actuator and release, thus also attracting the complaint of some users。
Under the overall situation increasingly emphasizing user's comfort now, noise when reducing electromagnetic actuator work just seems and is extremely necessary。Additionally, electric magnet can produce stronger vibrations when adhesive and release, also shake easily caused by light shape, and this vibrations also can cause the faults such as connection loosens, and affects the reliability of light type mapping device。
Therefore, the light type converting means of conventional car headlamp there is the problem that easily occur clamping stagnation in light type change procedure；Moment of torsion output instability, noise is big, and compatibility is not good。
