Rotating mechanism；When specific assembly, which can connect with plates of automobile, so that rotating mechanism is able to drive automobile lamp
It is whole to be rotated at least one direction.
In automobile lamp provided in an embodiment of the present invention, rotating mechanism can be used in the light modulation of automobile lamp.What light modulation referred to
It is after automobile lamp is installed on the corresponding installation site of metal plate of automobile, due to the part and rigging error of plates of automobile, auto lamp
Tool meeting relative theory design position has deviation, and the light shape for also allowing for car light has position deviation, needs according to normal place
The light shaped position of car light is adjusted, the position deviation of light shape is modified, the light shape that automobile lamp could be made to issue
Meet the requirement of regulation and actual use.The purpose that rotating mechanism is arranged is to drive part or all of light by the rotation of the mechanism
Element, more either entire car light are rotated at least one direction, so that the light shape of car light be made to be calibrated to correct position
It sets.
Specifically, in automobile lamp provided in an embodiment of the present invention, above-mentioned rotating mechanism can be preferably using spiral
Rotating mechanism.Screw type rotary mechanism has self-locking performance, and the rotating mechanism that light modulation is used on car light uses screw type rotary mechanism,
It is arranged on lamp body by screw rod, nut and is formed, it converts rotational motion into linear motion, and a components are specific around itself
The eccentric straight-line movement of axis is actually the rotary motion that the components are carried out around this specific axis, and car light uses this principle pair
The angle of light shape carries out position correction.
Fig. 4 is that automobile lamp provided in an embodiment of the present invention is applied on automobile and the Contrast on effect of the prior art is illustrated
Figure.
It is illuminated as shown in figure 4, being arranged using the automobile lamp for having car light mould group in automobile front, I is the prior art
The schematic diagram being mounted on vehicle body sheet metal 4, II is that automobile lamp of the invention is mounted on the schematic diagram on vehicle body sheet metal 4, from sky
Between occupy on, it can be seen that the present invention compared with the prior art, can be by the opening (opening especially in up and down direction) of car light
It is made very small, can adapt to the more vehicle configuration with technology sense and the following sense.
Herein it should be added that, the so-called front and rear, left and right of the embodiment of the present invention, up and down with the automobile lamp pacify
The front and rear, left and right of vehicle body coordinate system when loaded on vehicle body, unanimous between the higher and lower levels, the light direction of lenticular body 1 is front-rear direction, lamp body
The direction of 2 side is rear end, and the light direction of lenticular body 1 is front end.
The embodiment of the present invention also provides a kind of automobile, comprising: automobile lamp as described in any one of the above embodiments.
In automobile provided in an embodiment of the present invention, finally go out light due to being provided with lenticular body in automobile lamp as car light
Element adapts to the demand that vehicle light shape constantly becomes smaller so that the volume of car light greatly reduces；In addition, avoiding setting for lens
The loss caused by car light energy is set, optical efficiency is substantially increased.
Automobile lamp and automobile primary provided in an embodiment of the present invention will have following advantage:
One, the optical element due to lenticular body as the final light out of automobile front, the part and lamp body are directly connected
It connects, avoids the setting of lens in the prior art, therefore size of the car light on three-dimensional can greatly reduce, more favorably
In the shape-designing of car light, car light can be made smaller；
Two, due to saving final out optical element of the lens as the automobile lamp using car light mould group in the prior art,
Therefore the optical loss for avoiding lens about 15%, so that the optical efficiency of car light is significantly improved, certain
The power requirement of car light is also reduced in degree, is saved the energy, is reduced costs；
Three, since the mismachining tolerance and rigging error of lens in car light in the prior art are to the optical property shadow of car light
Sound is larger, and vehicle light shape is smaller and smaller and more curved, so that the refraction matched outside is passed through in the setting of lens to car light mould group
Afterwards, performance loss is also more serious, therefore present invention eliminates the setting of lens, using lenticular body as optical element is finally gone out, makes
The precision for obtaining car light optical system is improved, and optical property is more secure.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
