According to the invention, as the dimming connecting piece and the guiding support frame are additionally arranged, the designed length of the dimming screw is reduced, and torsion borne by the dimming screw is reduced; and besides, the guiding support frame fixed with the lamp housing is changed to support the heavier reflector component, so that the vibration resistance of the dimming mechanism is improved, further, the reliability and stability of the combined headlamp are bettered.
Description
Technical field
The present invention relates to automobile lighting system, particularly relate to the light modulation structure of illuminating lamp.
Background technology
As shown in Figure 1, minicar on current domestic and international market, the mode that the light modulation structure of comination headlamp normally adopts light modulation screw rod 1 and instant and near light reflector assembly 2 to be directly connected and fixed by plastic clamp 3, be that the adjustable side of light modulation screw rod is outside lamp housing, the other end puts in lamp housing, directly and reflector assembly by plastic clamp etc., be connected and fixed.The problem that this class formation exists is: 1, light modulation screw rod is long, and the front end reflector assembly that load capacity is larger again makes the suffered torsion of light modulation screw rod larger, light modulation difficulty, and the vibration resistance of dimming mechanism is bad; 2, light modulation screw rod is directly connected with reflector assembly, and reflector assembly wears no resistance, and falls under easily causing after reflector assembly mounting points wearing and tearing, the fault such as light modulation inefficacy, has a strong impact on light fixture reliability, even reduces lamp lighting performance, affects traffic safety.
Summary of the invention
The invention provides a kind of combined automobile headlight dimming mechanism, intend effectively reduce because of reflector assembly, wear no resistance and the long reflector assembly mounting points wearing and tearing that cause of light modulation screw torque after under fall, the problem such as light modulation difficulty, light modulation inefficacy.
For addressing the above problem, the present invention proposes following technical scheme:
Dimming mechanism of automobile headlamp of the present invention comprises light modulation screw rod and the spherical fixed card on traditional structure, and light modulation screw rod is mounted on lamp housing, and one end is outside lamp housing, and for regulating power input, the other end puts in lamp housing.Spherical fixed card is for being connected with the reflector assembly of headlamp.On traditional structure basis, light modulation connector and guide support frame have been increased.Light modulation connector one end and light modulation bolt are threaded connection, and the other end is by ball head structure and spherical fixed card clamping; Described guide support frame is arranged in lamp housing, and described light modulation connector is contained in guide support frame, can before and after guide support frame, slide.
Have above improvement visible, the present invention is mainly divided into light modulation bindiny mechanism light modulation screw rod, light modulation connector, guide support frame, spherical fixed card four parts.Light modulation connector and guide support frame two parts in traditional dimming mechanism, have been increased, shorten the design length of light modulation screw rod, reduce the suffered torsion of light modulation screw rod, and the carrying object of the larger reflector assembly of weight is transferred on the guide support frame fixing with lamp housing, dimming mechanism anti-vibration performance is promoted, improve the reliability and stability of comination headlamp.
The present invention has following advantages;
1, can effectively reduce because of reflector assembly wear no resistance and the long reflector assembly mounting points wearing and tearing that cause of light modulation screw torque after under fall, the problem such as light modulation difficulty, light modulation inefficacy;
2, dimming mechanism anti-vibration performance promotes, and improves the reliability and stability of comination headlamp;
3, simple in structure, applied widely.

In figure, 1-light modulation screw rod, 2-reflector assembly, 3-plastic clamp, 4-light modulation screw rod, 5-light modulation connector, 6-guide support frame, the spherical fixed card of 7-.
The specific embodiment
Below in conjunction with accompanying drawing, further describe structure of the present invention and working method:
As shown in Figure 1, the mode that the light modulation fixed structure of existing comination headlamp adopts light modulation screw rod 1 and instant and near light reflector assembly 2 to be directly connected and fixed by plastic clamp 3 conventionally, there is the problem that reflector assembly 2 wears no resistance and light modulation screw rod 1 moment of torsion is long, fall under easily causing after the 2 mounting points wearing and tearing of reflector assembly, the fault such as light modulation difficulty, light modulation inefficacy.
As shown in Figures 2 and 3, the present invention has increased light modulation connector 5 and guide support frame 6 two parts in traditional dimming mechanism, between comination headlamp lamp intracavity reflecting body assembly and lamp housing, be used for adjusting comination headlamp horizontal direction light angle, whole mechanism is divided into light modulation screw rod 1, light modulation connector 5, guide support frame 6, spherical fixed card 7 four parts.
Light modulation screw rod 1 is arranged on lamp housing, and one end, outside lamp housing, for regulating power input, can adopt manual adjustments, also connects motor, realizes automatically and regulating.Light modulation screw rod 1 other end puts in lamp housing.Light modulation connector 5 one end and light modulation bolt 1 are threaded connection, the ball head structure of the other end and 7 clampings of spherical fixed card.Spherical fixed card 7 is connected with the reflector assembly of headlamp.Guide support frame 6 is the boss structures that are integrally formed in lamp housing inner side, and position, on the installing hole of light modulation screw rod 1, connects before and after this boss structure, forms guided way in passage.Light modulation connector 5 is contained in guide support frame, and its cross section is " work " type, and both sides coordinate with the guided way in guide support frame 6, can before and after guide support frame, slide.
As shown in Figure 4 A and 4 B shown in FIG., A-A is the section key diagram after comination headlamp light modulation connector 5 coordinates with guide support frame 6.During light modulation, light modulation connector 5 slides in the parallel orbit of guide support frame 6, and light modulation connector 5 is interference fit with guide support frame 6, and " work " type structural design of light modulation connector 5 guarantees self-locking and the kinetic stability of mechanism well.
Working method of the present invention is as follows: during light modulation, rotate light modulation bolt 1, drive light modulation connector 5 to move in guide support frame 6, thereby drive the reflector assembly 2 being fixed in spherical fixed card 7 to move, realize comination headlamp dimming function.The design length of light modulation screw rod 1 has not only shortened in this mechanism by light modulation connector 5 and guide support frame 6 structures, reduced the suffered torsion of light modulation screw rod 1, also the carrying object of the larger reflector assembly of weight is transferred to the integrated guide support frame 6 of lamp housing on, dimming mechanism anti-vibration performance is promoted.
Light modulation screw rod material of the present invention has been changed into the composite material of nylon and ripple fibre by traditional round steel 20, effectively reduce the impact wear between each parts of dimming mechanism in comination headlamp vibration or light modulation process, improves the reliability and stability of comination headlamp.
