Abstract
The utility model discloses a car headlight dimmer, which comprises a casing (1), a motor (3), a transmission mechanism, screws (9) and a circuit board (2). An insert (4) is arranged between the motor (3) and the circuit board (2), the casing (1) consists of a front casing (1.1) and a back casing (1.2) in a connected manner, a flat face (3.1) of the motor (3) is parallel to a front panel of the circuit board (2), and a back panel of the circuit board (2) is abutted against a back end face of the back casing (1.2). When in assembly, the back end face of the back casing is arranged on a worktable, the circuit board is arranged below while the motor is arranged thereon, the insert between the circuit board and the motor is uniform in stress and not easy to deform or be loosened, and accordingly normal operation of the dimmer can be guaranteed.
Description
Technical field
The utility model relates to automobile lamp accessory field, particularly a kind of headlight for vehicles light adjuster.
Background technology
Headlight for vehicles light adjuster generally is positioned at the inside of headlight for vehicles, adjusts the speculum of headlight by adjuster and adjusts the horizontal level of light, thereby change the irradiating angle of the light of headlight for vehicles, satisfies when driving driving at night the demand to light.The patent No. provides a kind of automobile front shining lamp adjustment drive unit for 02280210 utility model patent, this dimming drive device drives Worm wheel transmission mechanism by motor, and the drive ball stud is done stretching motion, ball stud promotion mirror motion, thereby the adjustment of realization light horizontal level.The structure that the housing of this headlight for vehicles light adjuster is, splits around, motor, transmission mechanism and circuit board all are located in the housing, and connect by inserted sheet between circuit board and the motor.But circuit board and motor will be installed in the housing together when problem is to assemble, when mounted, the inserted sheet discontinuity between circuit board and the motor is distorted easily, thereby can produce looseningly, influences the operate as normal of adjuster.
Summary of the invention
Technical problem to be solved in the utility model is: provide the inserted sheet between a kind of circuit utmost point and the motor to be difficult for producing the headlight for vehicles light adjuster of distortion.
The technical scheme in the invention for solving the above technical problem is: a kind of headlight for vehicles light adjuster, comprise housing, motor, transmission mechanism, double-screw bolt and circuit board, be provided with inserted sheet between described motor and the circuit board, described housing is connected and composed by procapsid and back casing, the flat horizontal surface of described motor and the frontal plane of described circuit board be arranged in parallel, and the rear end face of the back plane of described circuit board and described back casing offsets.
Described transmission mechanism comprise the worm screw of the output shaft that is arranged on described motor, the worm gear that is meshed with described worm screw, with first gear of the coaxial setting of described worm gear and second gear that is meshed with first gear; The axis hole wall of described second gear is provided with the internal thread that matches with described double-screw bolt.
Compared with prior art, advantage of the present utility model is: the flat horizontal surface of the motor of this headlight for vehicles light adjuster and the frontal plane of circuit board be arranged in parallel, and the rear end face of the back plane of circuit board and described back casing offsets.Rear end face in when assembling with back casing is placed on the workbench, at this moment circuit board down, motor is last, the inserted sheet between circuit board and the motor is stressed evenly like this, is difficult for producing being out of shape, and can not become flexible, and can guarantee the adjuster operate as normal.
Description of drawings
Accompanying drawing is the decomposition texture schematic diagram of the utility model headlight for vehicles light adjuster.
In the accompanying drawing: 1 housing, 1.1 procapsids, 1.2 back casings, 2 circuit boards, 3 motors, 3.1 flat horizontal surfaces, 4 inserted sheets.5 worm screws, 6 worm gears, 7 first gears, 8 second gears, 9 double-screw bolts.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in drawings, a kind of headlight for vehicles light adjuster, comprise housing 1, motor 3, transmission mechanism, double-screw bolt 9 and circuit board 2, be provided with inserted sheet 4 between described motor 3 and the circuit board 2, described housing 1 is connected and composed by procapsid 1.1 and back casing 1.2, the flat horizontal surface 3.1 of described motor 3 be arranged in parallel with the frontal plane of described circuit board 2, and the rear end face of the back plane of described circuit board 2 and described back casing 1.2 offsets.
In this specific embodiment, described transmission mechanism comprise the worm screw 5 of the output shaft that is arranged on described motor 3, the worm gear 6 that is meshed with described worm screw 5, with first gear 7 of described worm gear 6 coaxial settings and second gear 8 that is meshed with first gear 7; The axis hole wall of described second gear 8 is provided with the internal thread that matches with double-screw bolt 9.
When needs are regulated the light of headlight for vehicles, rotation by circuit board 2 control motors 3, transmission by worm screw 5 and the worm gear 6 that is meshed with it reduces rotating speed, and further rotating speed is reduced by the transmission with first gear 7 of worm gear 6 coaxial settings and second gear 8 that is meshed with first gear 7; Because the rotation of second gear 8, double-screw bolt 9 in second gear, 8 axis holes rotates simultaneously, because the front end of double-screw bolt 9 is connected with the bulb push rod, therefore the rotation of double-screw bolt 9 will promote moving forward and backward of bulb push rod, thereby can drive the reflective mirror motion of headlight for vehicles, change the irradiating angle of the light of headlight for vehicles, satisfy when driving driving at night demand light.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
