A connecting piece and a shaft which can cause a lamp bowl of the head lamp downwards right rotate are arranged on the external wall of the lamp bowl of the head lamp. The inner wall of a shield of the head lamp is provided with a return spring of the lamp bowl of the head lamp and a shaft sleeve for containing a shaft of the lamp bowl of the head lamp, the connecting piece is connected with an electromagnet, and the contact end of the electromagnet is connected with a sensitization controlling circuit. The utility model efficiently solves the problem that driver's eyes are stimulated by light, and the sight is affected at the time of meeting at night, and the utility model has the advantages of reasonable design, simple structure, convenient installation and repair, etc.

Description

Automatic steering variable-focus means for vehicle headlight

The utility model relates to a kind of device that makes the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic steering change irradiating angle and direction.

It is reported that the headlight of installing on the automobile all can not rotate at present, therefore when nighttime meeting, both sides' vehicle need carry out conversion light, otherwise will influence safety traffic.Though someone has designed the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht that rotates with bearing circle, but still can't resolve the problem of nighttime meeting.

The purpose of this utility model is in order to overcome above-mentioned deficiency, to provide a kind of reasonable in design, simple in structure, be convenient to installation, maintenance, can making the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic steering change the device of irradiating angle and direction.

Technical solution of the present utility model is, when solving cars meeting at night, driver's eyes are not subjected to the stimulation of headlight light, realize that the headlight automatic steering changes the purpose of irradiating angle and direction, outer wall at headlight lamp bowl is provided with attaching parts and makes the axle of headlight lamp bowl to the lower right rotation, inwall at big lamp shield is provided with headlight lamp bowl retracing spring and for the axle sleeve of adorning headlight lamp bowl axle, is connected with electromagnet on the attaching parts of headlight lamp bowl outer wall.On electromagnet, be connected with the sensitization control circuit.

The utility model compared with the prior art, owing on Der Scheinwerfer mit FernlichtAbblendlichtStandlicht lamp bowl and big lamp shield, be provided with the device that can make the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic steering change irradiating angle and direction, when therefore not only having solved nighttime meeting effectively, driver's eyes are subjected to the problem of light stimulus effects vision, and have reasonable in design, simple in structure, be convenient to advantages such as installation, maintenance.

Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail

Fig. 1 is sensitization control circuit figure of the present utility model

Fig. 2 is structural representation of the present utility model and working state figure.

Referring to Fig. 1, Fig. 2, on the left and right sides outer wall of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht lamp bowl 4, be welded with the axle 2 that is oblique line that Der Scheinwerfer mit FernlichtAbblendlichtStandlicht lamp bowl 4 is rotated to the lower right.On the outer wall of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht lamp bowl 4 bottoms, be welded with an attaching parts 8 that has axis hole.On attaching parts 8, be connected with pull bar 7 by bearing pin.The other end at pull bar 7 is connected with the square pivoted arm 6 that has positioning shaft hole by bearing pin, and square pivoted arm 6 is fixed on the car body by the fix shaft that is inserted in the positioning shaft hole.The other end of square pivoted arm 6 is connected on the drive link 5 of electromagnet DT by bearing pin.Attaching parts 8, pull bar 7, square pivoted arm 6, drive link 5 are made by iron plate.Inwall at big lamp shield 1 is fastened with the sheet retracing spring 9 that headlight lamp bowl 4 is resetted by screw 10.A, B terminals at electromagnet DT are connected with by photoconductive cell Rm, resistance R ₁, R ₂, R ₃, potential device W, capacitor C ₁, C ₂, IC ₁, IC ₂, diode D ₁, D ₂, the sensitization control circuit that constitutes of relay J, relay switch JK, change-over switch SW.Its photoconductive cell Rm and resistance R ₁, potential device W series connection.Resistance R ₂An end be connected resistance R ₁And on the point of attachment between the photoconductive cell Rm, the other end is connected on resistance R ₃, capacitor C ₁Parallel connection point on, and and IC ₁Input end e connect.IC ₁A end be connected potential device W and IC ₂G end between point of attachment on.Diode D ₁Negative pole end and IC ₁Mouth b connect positive terminal and diode D ₂Positive terminal and an end of relay be connected.Change-over switch SW and power positive end, IC ₂F end, an end of relay J connect.Capacitor C ₂An end link to each other with the positive pole of power supply, the other end links to each other with the negative pole of power supply, and in parallel with electromagnet DT.Between electromagnet DT and power cathode, be connected with relay switch JK.Photoconductive cell Rm, resistance R ₃The other end, diode D ₂Negative pole end and IC ₁, IC ₂Input end d, h link to each other with the negative pole of power supply.Be provided with collector G at photoconductive cell Rm place.Collector G and photoconductive cell Rm are contained in the columnar shell, and with its position that is installed in the place ahead of automobile cab or is convenient to receive the other side's car bulb.Electromagnet DT is installed in the big lamp shield 1.Other components and parts are contained in the can, and change-over switch SW is installed in gauge panel place in driving or the place of being convenient to handle.Change-over switch SW for automatically, manually, stop change-over switch.When day driving installs without this, change-over switch is placed the P position.During night travel, change-over switch is placed the n position.If this device when automatically part breaks down, places the q position with change-over switch SW, make the headlight handling maneuver that follows the pattern of, promptly manually behaviour does.This device may command headlight rotates 9 °～10 ° to the lower right.
