Abstract: A device for controlling high beam and low beam of a headlight includes a fixing plate formed with a recess and bored with two pin holes, two curved slots and a sliding slot. A valve base secured on the fixing plate is installed therein with an electromagnetic valve having a valve rod inserted in the interior and a spring fitted on the valve rod. A positioning seat is mounted on the valve rod and has one side provided with a connecting rod to be inserted through two mutually overlapped ends of two connecting plates and in the sliding slot of the fixing plate. Two boards are oppositely and pivotally assembled on the fixing plate, having their lower sides respectively and pivotally connected with the upper ends of the two connecting plates by insert pins, which are then inserted in the two curved slots of the fixing plate.

Abstract: A step motor used to adjust a headlight's up and down includes a supporting pole, a magnet, a coil and a circuit board. The circuit board has a power input terminal subsequently connected with a voltage regulator IC, a control IC, a transistor and a driver. In addition, the driver is connected with the coil; the control IC is connected with a signal input terminal further connected with a vehicle compute; the power input terminal is connected with a vehicle power source. So when a vehicle is started, power can flow through and regulated by the voltage regulator IC. Then it runs through the control IC to command the driver to drive the negative coil to induce the magnet to rotate clockwise or counterclockwise, enabling the supporting pole to move inward or outward to horizontally balance the headlight.

Abstract: A step-by-step motor able to carry out up-and-down transmission includes a housing, a top rod, a circuit board, a magnet, a coil unit and a cover. The top rod is inserted in an insert hole of the housing, having a wall bored with a cut recess. The circuit board has a position-limiting switch received in an engage groove of the housing and provided with a sidewise rod inserted in the cut recess of the top rod. The magnet is fixed with a connecting member connecting a bearing, and the lower end of the top rod is engaged with the connecting member. The coil unit is fitted around the magnet and positioned in the housing, and the cover is covered on the bottom of the housing. The magnet is driven by the coil unit to rotate and actuate the top rod to move upward or downward steadily.

Abstract: An automobile headlight high-low switching device includes a fixing plate, an electromagnetic valve, a driven device and a light-shielding board. The fixing plate has a recess, a sliding slot and a pivotal pin. The electromagnetic valve is fixed on the fixing plate, provided with a valve shaft mounted with a spring. The driven device is connected with the valve shaft, having a projecting bar at a bottom to plug into the sliding slot. The light-shielding board has a pivotal hole used to be pivotally fixed with the pivotal bar of the fixing plate, a through hole to be inserted through by the projecting bar of the driven device. With the simple components, the automobile headlight high-low switching device can be not only operated smoothly but also assembled quickly to effectively lower manufacturing cost.

Abstract: A brushless motor includes a bottom base, a circuit board, a rotator, a big gear, a big driven gear, a driving gear and a lid. Positioned around a shaft base inside the bottom base are two stopping posts that form an included angle with the shaft base. A positioning plate is formed at the bottom of the driving gear, restricted to move between the two stopping posts to keep the driving gear rotated in a preset angle. And, a single injection mold can make various bottom bases with diverse rotating angles for being used in the brushless motor employed for different lamps, achieving the purpose of reducing manufacturing cost.

Abstract: An adjusting device for automobile headlamp projection angle comprises a case, a bearing ring, a connection beam, a magnet, a main axle, a pair of forward-wound coil and backward-wound coil, a pair of active transmission gear wheel and passive transmission gear wheel, and a circuit board. The circuit board controls the charging of the coils, determining the poiarity of the magnet, whereby the transmission gear wheels will move and drive an up or down shift of the main axle. A stopping piece mounted on the passive transmission gear wheel will move and confine the movement of the main axle between an upper and a lower limits, which limits are controlled by a handle on the circuit board. Therefore, over-extension and over-contraction of the main axle can be prevented. Further, the transmission will be more sensitive, and the total volume of the device will be small.
