Description
Technical field:
The utility model relates to a kind of far and near lamp control apparatus of car light.
Background technology:
The far and near lamp control apparatus of existing a kind of car light, it comprises housing, coil assembly, a permanent magnet and a bulb, described housing is an end opening vertically, the other end is provided with the tail-hood sealing, tail-hood is provided with a pad, the pad center is provided with a connecting element, described permanent magnet in the form of a ring and be fixedly arranged on the pad of tail-hood, described coil assembly is that central authorities are provided with the line wheel that perforation and outer rim are arranged with wire rod, be provided with one in the connecting element and act on the retracing spring that line is taken turns, the line wheel is located between permanent magnet inner ring surface and the connecting element and can be moved forward and backward under the application force of retracing spring and permanent magnet, and described bulb connects the online end that is different from the housing tail-hood of taking turns.Produce the magnetic field opposite with permanent magnet polarity when the coil assembly on the line wheel is switched on, the effect that makes the line wheel overcome retracing spring is adsorbed mutually with permanent magnet backward, moves the high lamp of formation (lamp far away) backward thereby drive bulb; When the coil assembly outage on the line wheel, the line wheel resets under the effect of retracing spring, bulb is moved forward form low lamp (low beam).But there is following defective in it: 1, described permanent magnet is fixed on the pad of tail end cover bottom, and the line wheel is located between permanent magnet inner ring surface and the connecting element, so the heat that coil produced of line wheel can pass to permanent magnet earlier, pass to tail-hood by permanent magnet again and realize heat radiation, can not fast heat be distributed, influence the service life of permanent magnet and coil; 2, all draw because of the power input line of bulb and coil from the sidewall of housing, so when the line wheel moves forward and backward, the power input line that it will inevitably involve bulb power input line and coil, retractility and smooth degree that bulb is moved in housing are affected; 3, because the power input line of bulb and coil is all drawn from the side-wall hole of housing, cover so must be provided with on the lateral wall of housing with the corresponding line ball of side-wall hole, complex structure, manufacturing cost is higher; 4, be typically provided with water proof ring between the joint portion of tail-hood and housing, because no any screens structure on the tail-hood, so before tail-hood and housing assembling, water proof ring generally can not be installed on the tail-hood in advance; 5, described pad and the connecting element that is installed on the tail-hood is one-body molded by hardware, the structure relative complex, and be located at because of permanent magnet on the pad of tail-hood, so when product assembles, must arrange special pressure magnet personnel, the cost of labor height, and production efficiency is lower.
