Fixedly the one binding has a motor frame 111, CD-ROM drive motor 130 to be arranged in the motor frame 111 on the anti-dazzle device 110, and CD-ROM drive motor 130 is in order to drive hunting gear 140.
Drive device 160 and comprise two firm framves 161, a drivening rod 162 and an inverted impulse body 163, two firm framves 161 and be located at fixedly anti-dazzle device 110 opposite sides, and two supports 112 and two firm frame 161 corresponding and left-right symmetric.Tool one arc pendulum space in the firm frame 161.Inverted impulse body 163 is installed with rotationally in the pivot spaces of motor frame 111; And inverted impulse body 163 1 end one are attached on the quadrant gear 142; In this embodiment quadrant gear 142 be arranged at driven wheel 141 in CD-ROM drive motor 130 rotating shafts transmission of power that is meshing with each other, aforesaid pivoted body 163 is with quadrant gear 142 reciprocal turns.And drivening rod 162 1 end groups are located at inverted impulse body 163 other ends, and the bearing of trend of drivening rod 162 is vertical each other with normal F, and drivening rod 162 is subject in the two firm framves 161 toward the displacement of restrike of arc pendulum.
Movable anti-dazzle device 120; Spacing movably fixedly between anti-dazzle device 110 and the firm frame 161; Movable anti-dazzle device 120 tops have light shielding part, and the salient of movable anti-dazzle device 120 utilization one forms two caulking grooves 121, and caulking groove 121 is open outwardly along normal F direction; Two caulking grooves, 121 left and right symmetricallies are disposed at movable anti-dazzle device 120; And drivening rod 162 2 ends are installed with respectively in two caulking grooves 121, borrow the space of two caulking grooves 121 to allow drivening rod 162 along the free displacement of normal F direction, and the displacement of drivening rod 162 vertical normal F directions then can drive activity anti-dazzle device 120.
Other is provided with balanced connecting rod 143; Balanced connecting rod 143 1 ends are fixed in the pivot axle center of quadrant gear 142; The bearing of trend of balanced connecting rod 143 is vertical each other with normal F, and balanced connecting rod 143 is arranged at the fixedly opposite side of anti-dazzle device 110, then is provided with a piece 144 at balanced connecting rod 143 other ends; Balanced connecting rod 143 and the spacing rotationally revolution space in two supports 112 of axle piece 144; And balanced connecting rod 143 is with axle piece 144 interlock drivening rods 162, makes balanced connecting rod 143 and drivening rod 162 carry out the reciprocating action of similar seesaw in fixing anti-dazzle device 110 2 sides, so as to keeping the degree of stability of movable anti-dazzle device 120 when the displacement.Balanced connecting rod 143 is arranged at fixedly the same side of anti-dazzle device 110 with CD-ROM drive motor 130 in this embodiment, promptly with respect to the opposite side of light source 101.
In detail, hunting gear 140 is because of the effect of CD-ROM drive motor 130, and drive activity anti-dazzle device 120; That is movable anti-dazzle device 120 carries out start up or down along arrow D; Movable anti-dazzle device 120 starts to location only must stop the supply of power of CD-ROM drive motor 130 after making light source 101 produce the light type of passing light or country beam, and movable anti-dazzle device 120 just can be because of the effect of reset attachment 150; And return to originally initial position, so can carry out the light type adjustment of another time again.
In addition, see also the manner of execution scheme drawing of the utility model that Fig. 4 illustrates.Originally the start of CD-ROM drive motor 130 is to rotate to be the master, and when driven wheel 141 drove quadrant gear 142, it was main with what rotate as flowing mode in fact still.Then, inverted impulse body 163 is with quadrant gear 142 reciprocal turns.And drivening rod 162 1 ends are installed in inverted impulse body 163; So inverted impulse body 163 drives drivening rod 162 and rotates; According to reason drivening rod 162 should continue quadrant gear 142 in the past the mode of restrike of arc pendulum come start; But this embodiment not only limits the reciprocal start scope of quadrant gear 142; Make drivening rod 162 only can be in limited scope back and forth start, more the caulking groove 121 through drivening rod 162 and movable anti-dazzle device 120 absorbs the amount of power of doing of the non-above-below direction along arrow D of quadrant gear 142.But be 110 displacements of movable anti-dazzle device 120 relative fixed anti-dazzle devices, the movable anti-dazzle device 120 of this embodiment is along 110 upper and lower displacements of arrow D relative fixed anti-dazzle device.
In order to keep the degree of stability of movable anti-dazzle device 120 when the displacement; This embodiment has designed balanced connecting rod 143 in addition; When movable anti-dazzle device 120 displacements; Can make activity anti-dazzle device 120 both sides that balanced connecting rod 143 and drivening rod 162 corresponding reciprocally swingings are arranged respectively, reach the balance of action stress whereby; This embodiment will make balanced connecting rod 143 and drivening rod 162 be set to be parallel to each other, and make movable anti-dazzle device 120 when displacement, can carry out start more stably, and movable stress disperses balance.It should be noted that balanced connecting rod 143 is merely keeps the degree of stability of movable anti-dazzle device 120 when displacement, and inessential assembly.
Can know by above-mentioned embodiment; Use the car light switching mechanism 100 of the utility model; Being adjusted into as flowing mode of movable anti-dazzle device 120 is parallel to fixedly that anti-dazzle device 110 moves up and down, and the assembling process that not only can simplify the internal structure of an organization more reduces the quantity and the cost-cutting of part simultaneously.In addition, this kind of the movable anti-dazzle device 120 of this embodiment made flowing mode, can have more stable lamp handover mechanism near far away.
Though the utility model discloses as above with all embodiments; Right its is not in order to limit the utility model; Anyly be familiar with this art; In spirit that does not break away from the utility model and scope, when can doing various changes and retouching, so the protection domain of the utility model is as the criterion when looking the scope that appending claims defines.
