Problems solved by technology

[0003] Because the linear moving screw moves axially through the nut part of the motor magnet axis, and uses the rectangular hole positioning of the motor casing to perform linear movement, but the linear moving screw does not perform axial positioning, resulting in When the linear screw is extended, the closer to the maximum stroke, the greater the axial sway, which makes the stability of the movement displacement poorer.

Abstract

The invention relates to a car lamp steering system driving device. The car lamp steering system driving device is characterized by comprising a base, a lamp support, a stepper motor assembly, a movable piece and a rotating rocker arm. The lamp support is connected with the base in a pivot mode, the stepper motor assembly is arranged on the base and provided with an output screw shaft, the output screw shaft can rotate but can not move along the axial direction, the movable piece is provided with a main body and a connecting part, the main body is meshed with the output screw shaft, the rotating rocker arm is provided with a first end and a second end, the first end is fixed on a lamp support, and the second end is connected with the connecting part of the movable piece. Due to the fact that the output screw shaft of the stepper motor assembly is transmitted in a rotating movement mode and fixed on a supporting part on the base, and thus the moving stability of the movable piece is greatly improved.

Description

technical field [0001] The invention relates to a headlight capable of changing the irradiation angle, in particular to a driving device for a car light steering system driven by a stepping motor to achieve the adjustment effect. Background technique [0002] The known driving device for the steering system of the vehicle lights, such as the structure disclosed in US Patent No. 7,223,001, includes a headlight support and a linear actuator, which is used to drive the headlight support deflection, and includes a motor (motor), a linear-movement screw (linear-movement screw) and a set of components (coupling part), the linear-movement screw is connected between the motor and the component, and has a The cavity is used for inserting the coupling end of the headlamp support base. Thus, when the screw rod is driven by the motor to move axially, the assembly part can drive the headlight support base to rotate, so as to achieve the purpose of adjusting the irradiation direction of ...
