Description
Technical Field
The invention relates to the technical field of automobile headlamps, in particular to a split type reflector dimming structure.
Background
As important elements essential for exterior modeling of automobiles, automotive headlamps are increasingly provided with more and more functions, and the designs of headlamps are also becoming diverse.
In the case of a relatively conventional reflex headlamp, fig. 1a shows a front view of a dimming structure of a two-chamber reflex headlamp of the prior art, and fig. 1b shows an isometric view of a dimming structure of a two-chamber reflex headlamp of the prior art, as shown in fig. 1a and 1b, a low beam dimming unit and a high beam dimming unit are usually arranged in a lamp body of a two-chamber reflex headlamp.
The low-beam dimming unit includes a low-beam left-right dimming structure 103 and a low-beam up-down dimming structure 104, and the high-beam dimming unit includes a high-beam up-down dimming structure 105 and a high-beam left-right dimming structure 106.
Although both the low beam reflector 102 and the high beam reflector 101 can achieve both vertical and horizontal dimming, the low beam shape of a single reflector cannot be ensured well.
In order to solve the problem, the near light function can be split into two cavities, and the two cavities and the far light form a three-reflection-cavity headlamp.
Fig. 2a shows a front view of a three-cavity reflective headlamp dimming structure of the prior art, fig. 2b shows an isometric view of the three-cavity reflective headlamp dimming structure of the prior art, such as the three-cavity reflective headlamp dimming structure shown in fig. 2a and 2b, which fixes two low beam reflectors 202 together for dimming, the low beam dimming unit includes a low beam left and right dimming structure 203 and a low beam up and down dimming structure 204, the high beam reflector 201 is a single dimming structure, and the high beam dimming unit includes a high beam up and down dimming structure 205 and a high beam left and right dimming structure 206.
The three-cavity reflective headlamp dimming structure shown in fig. 2a and 2b has the disadvantage that the relative positions of the two low beam reflective cavities cannot be adjusted, and are limited by the process and precision, so that the deviation is easily generated, and the low beam shape is deteriorated.
In addition, fig. 3a discloses a front view of a manual dimming structure in the prior art, and fig. 3b discloses an axonometric view of the manual dimming structure in the prior art, such as the common manual dimming structure shown in fig. 3a and 3b, which is composed of a housing 301, a dimming ball screw 302 and a dimming bracket 303, and the dimming point 304 of the ball is driven by a screw-nut linear motion mechanism to translate and rotate for realizing internal or external dimming.
When the lamp is used for internal dimming, the defect is that a dimming tool is required to extend into the lamp body by opening the rear cover of the lamp body, so that the dimming step is added, and the process is complex;
when the lamp is used for external dimming, the external dimming can be carried out by using a dimming tool, but the sealing risk is high, and the leakage of the lamp body is easy to occur;
in addition, the structure can only be used for realizing manual dimming, and cannot be simultaneously applied to two modes of manual dimming and electric dimming.
