Requirement processed, so xenon headlight is equipped with automatic horizontal light adjusting system.And halogen regenerative-cycle headlamp luminous flux is relatively low, and nothing
Regulation Qiang Zhiyaoqius, it is contemplated that the factor of cost, is only equipped with hand-operating light device so general.
As depicted in figs. 1 and 2, existing automatic horizontal light adjusting system is by being respectively arranged in vehicle body front axle and rear axle
1,1 controller 3 of 2 height sensors and 2 stepper motors 2 form.When bodywork height changes
Time, front axle and rear axle height sensor can export different voltage signals or pwm signal in real time to controller,
Controller can calculate vehicle body relative to initial bit according to output signal and the vehicle body wheelbase of antero posterior axis height sensor
The inclination angle put, then adjusts the irradiation height of headlamp, thus compensates this change by controlling stepper motor.
The system of existing this automatic horizontal light adjusting system constitutes complexity, and with high costs, dimming mode also relative to
Complicated.

For installing the luminous source of headlight on light modulation support.
Further, according to the automatic horizontal light adjusting system for car headlamp described in the utility model, described
2 d.c. motors rotating shaft by drive mechanism connect light modulation axle.
Further, according to the automatic horizontal light adjusting system for car headlamp described in the utility model, described
The main support of height sensor is fixed on the parts that automobile chassis suspension is the most constant with vehicle body holding, secondary
Frame is fixed on automobile chassis suspension to be had on the parts of relative motion with vehicle body.
Further, according to the automatic horizontal light adjusting system for car headlamp described in the utility model, described
Height sensor be installed on automobile hind axle position.
Further, according to the automatic horizontal light adjusting system for car headlamp described in the utility model, described
Height sensor be installed on automobile front axle position.
The beneficial effect that this utility model reaches: automatic horizontal light adjusting system of the present utility model includes a vehicle body height
Degree sensor and 2 d.c. motors, compare existing light adjusting system and save 1 controller and 1 height sensor,
And the stepper motor of 2 high costs has been changed into the d.c. motor of 2 low costs, simplifying whole light adjusting system
While also greatly reduce the cost of automatic horizontal light adjusting system.

Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown on figure 3, automatic horizontal light adjusting system described in the utility model includes 1 for detecting bodywork height
The height sensor of change and 2 are for controlling the d.c. motor that front shining lamp adjustment mechanism carries out dimming, vehicle body
The main support of height sensor is fixed on the parts that automobile chassis suspension is the most constant with vehicle body holding, and assistant support is solid
It is scheduled on automobile chassis suspension to have on the parts of relative motion with vehicle body.2 d.c. motor correspondence regulations two respectively are big
The dimming mechanism of lamp.
In a preferred embodiment, height sensor is installed on shaft position after vehicle body, in other embodiments,
Height sensor can also be arranged at vehicle body front axle, but dimming effect is not as being installed on rear axle.Because rear axle
Loading the impact on body gesture relatively big, rear stall people and luggage case are fully loaded with under making vehicle body rear axle height significantly
Fall, causes light the most upwards to irradiate, and front-seat seat people, little on the impact of front axle bodywork height.
As shown in Figure 4, the dotted arrow in figure represents that mechanical connection, solid line represent electrical connection.2 d.c. motors
Being driven by respective driving control circuit, the signal output part of described height sensor connects driving and controls electricity
The signal input part on road, the signal output part drive connection d.c. motor of described driving control circuit, described 2 straight
The rotating shaft of stream motor installs light modulation axle by drive mechanism respectively, and each light modulation axle is connected respectively in two headlights
Light modulation support, for installing the luminous source of headlight on light modulation support.
Height sensor detects bodywork height change in real time, and exports different pwm signals in real time to driving
Control circuit, drives control circuit that pwm signal is converted into voltage signal.Car is detected when driving control circuit
When the input voltage of body height sensor is variant with the voltage within motor, work order can be sent and drive direct current horse
Reaching rotation, thus drive the flexible of light modulation axle, d.c. motor, in driving light modulation axle telescopic process, promotes light modulation
Frame fore-aft motion, thus adjust car light irradiation direction, when input voltage and motor that height sensor detected
When internal voltage is consistent, d.c. motor quits work, and light modulation completes.
When dimming elongate axis, promoting forward light modulation support, light is aimed downwardly, as shown in Figure 5；When light modulation axle
During contraction, pulling back light modulation support, light upwards irradiates, as shown in Figure 6.
Automatic horizontal light adjusting system of the present utility model includes a height sensor and 2 d.c. motors, phase
1 controller and 1 height sensor is saved than existing light adjusting system, and by the stepper motor of 2 high costs
Change the d.c. motor of 2 low costs into, while simplifying whole light adjusting system, also greatly reduce automatic water
The cost of Heibei provincial opera photosystem.
