Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1, the utility model provides a dimming mechanism for automobile headlamp, dimming mechanism includes:
the lamp base 1 is used for fixing a lamp and is used as a supporting piece of a dimming mechanism;
the light adjusting screw rod 2 is provided with threads and penetrates through the lamp base 1;
the light adjusting gear 3 is sleeved and fixed on the light adjusting screw rod 2;
the limiter 4 is sleeved at one end of the dimming screw 2 with threads and is provided with a thread groove block 41 matched with the threads on the dimming screw 2;
the dimming support 5 is connected with the other end of the limiter 4;
wherein, the extreme end of the screw thread of the light adjusting screw rod 2 is provided with a flanging limiting block 21; drive the screw rod 2 of adjusting luminance through rotating the gear 3 of adjusting luminance and rotate, adjust luminance the screw rod 2 and cooperate through screw thread and screw thread groove block 41 to drive stopper 4 and remove, when screw thread groove block 41 removed to the screw thread end, turn-ups stopper 21 supported the side of screw thread groove block 41, in order to realize adjusting luminance and be difficult for breaking away from between the support 5 of adjusting luminance.
Specifically, the lamp base 1 has a through hole 11;
the through hole 11 is matched with the dimming screw rod 2, and the dimming screw rod 2 can rotate in the through hole 11.
Specifically, the dimming screw 2 includes a rotation region 22 and a thread region 23 with a stopper 24 between the rotation region 22 and the thread region 23;
the light adjusting gear 3 is sleeved and fixed in the rotating area 22, and the limiter 4 is sleeved in the threaded area 23;
after the light adjusting screw 2 passes through the through hole 11, the stopper 24 will abut against the lamp base 1.
In particular, the stop 4 also has a travel zone 42;
the travel zone 42 is to the right of the thread groove block 41 and has an inner wall 43;
when the side surface of the limiting groove block 41 is abutted against the flanging limiting block 21, the side surface is the maximum position of the stroke area 42, and when the flanging limiting block 21 is abutted against the inner wall 43, the side surface is the minimum position of the stroke area 42.
Specifically, the limiter 4 further comprises a connecting rod 44, and the limiter 4 is connected with the dimming bracket 5 through the connecting rod 44; the connecting rod 44 is cylindrical as a whole and has a spherical end.
Specifically, the dimming stand 5 is fitted with the connection rod 44, and the connection rod 44 is rotatable within the dimming stand 5.
Specifically speaking, clockwise rotation dimming gear 3 drives dimming screw 2 and carries out synchronous rotation, and screw thread through dimming on the screw 2 and the screw thread groove piece 41 on the stopper 4 mutually support, drive stopper 4 removes to drive the motion of adjusting luminance support 5, when stopper 4 removes the end to threaded area 43, turn-ups stopper 21 can block screw thread groove piece 41, thereby prevents that stopper 4 and dimming screw 2 from droing. In addition, when the light adjusting gear 3 rotates counterclockwise, the light adjusting screw 2 rotates synchronously, at the moment, the thread on the light adjusting screw 2 is matched with the stopper 4, the stopper 4 moves towards the direction close to the lamp base 1, the thread groove block 41 gradually becomes far away from the flanging limiting block 21, and when the flanging limiting block 21 abuts against the inner wall 43 of the stroke area 42, the stopper 4 reaches the minimum stroke. When the stopper 4 moves to the limit distance of both ends, the stopper 4 can rotate together with the dimming screw 2, and at this time, since the connection position of the stopper 4 and the dimming support 5 is a cylinder and a sphere, the stopper 4 can rotate in the dimming support 5 and can be connected with the dimming support 5.
When the movement amount of the existing dimming mechanism is large, the fixing buckle is easy to fall off from the dimming mechanism, so that the dimming system fails, and the use of the whole headlamp is influenced. Dimming disabled vehicles need to exit dimming lines and workers need to repair and replace new lamps. The dimming mechanism after optimizing is limited to prevent the sliding when the dimming mechanism is limited, and the dimming mechanism is moved in a fixed stroke, so that the dimming mechanism is more stable in use, and unnecessary manpower and material loss are effectively reduced.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
