The utility model solves the problems of the technologies described above adopted technical scheme: automobile reading lamp light conductor assembly structure, comprise reflective mirror and light conductor, this reflective mirror has installing hole, aforesaid light conductor is located on the installing hole of reflective mirror, the outside that it is characterized in that described light conductor forms draw-in groove and positioning bar, the front end of described light conductor forms annular shoulder portion, accordingly, the slot that the rear end face of described reflective mirror has the buckle of the wedge shape coordinating with aforementioned draw-in groove clamping and coordinates with aforementioned positioning bar, described reflective mirror has the position-arresting part fitting with aforementioned shoulder portion around installing hole, aforesaid buckle and slot are arranged around installing hole.
Described light conductor comprises connecting portion and takes shape in successively from front to back the first convex lens, the second convex lens and the 3rd convex lens on connecting portion, the front end face of aforementioned the first convex lens has exiting surface, the rear end face of aforesaid the 3rd convex lens has incidence surface, and the outside of aforementioned connecting portion forms described draw-in groove and positioning bar.
The light of illuminator enters after light conductor, through multiple convex lens to the gathering of light with refraction after from light conductor exiting surface out, wherein a small part light reflects from light conductor edge surface, can be absorbed by near face frame light conductor and the face of speculum, from light conductor exiting surface light out, part is after speculum refraction, and entirely through transmissive mirror out, it is better that field of illumination forms brightness value uniformity to last light.Light conductor is made convex lens form, utilizes luminous intensity distribution assistant software, by the adjustment to the multiple convex lens profiles of light conductor, can realize fast the adjustment to opticpath and distribution of light, bright dipping is reached meet the illumination functions of designing requirement.The light conductor of convex lens form has reduced the wall thickness of product, is easy to the injection molded of product.
As preferably, described connecting portion indent forms a built-in groove, front end projection one back-up block, and the second described convex lens and the 3rd convex lens take shape in this built-in groove and expose end, the first described convex lens take shape on back-up block, and this back-up block root is formed with described shoulder portion.
Further, the axis of described the first convex lens and the length direction of light conductor are an obtuse angle.Be beneficial to light and form preferably effect of brightness value uniformity in field of illumination.
As improvement, the rear end face of described the 3rd convex lens offers groove, and this groove forms incidence surface.
Further, described slot is two and is arranged in buckle both sides.
Compared with prior art, the utility model has the advantage of: light conductor packs in reflective mirror, by being clasped of its draw-in groove and reflective mirror, retreat to packing direction into thereby placed restrictions on light conductor; The circular bead surface of light conductor head, in assembly direction and reflective mirror laminating, has been placed restrictions on light conductor and has been continued to enter to assembly direction; The positioning bar of light conductor coordinates with slot, reaches light conductor and packs after reflective mirror in level two directions not play into.Reach the restriction of light conductor three direction frees degree in reflective mirror, realized being fixedly connected with of light conductor.Integral installation small volume, and, install convenient firm.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As Fig. 1, shown in Fig. 2 and Fig. 3, automobile reading lamp light conductor assembly structure in the present embodiment comprises reflective mirror 2 and light conductor 3, this reflective mirror 2 has installing hole 1, light conductor 3 is located on the installing hole 1 of reflective mirror 2, shown in Fig. 4 and Fig. 5, the outside of light conductor 3 forms draw-in groove 37 and positioning bar 35, the front end of light conductor 3 forms annular shoulder portion 36, accordingly, the slot 23 that the rear end face of reflective mirror 2 has the buckle 22 of the wedge shape coordinating with draw-in groove 37 clampings and coordinates with positioning bar 35, reflective mirror 2 has the position-arresting part 24 fitting with shoulder portion 36 around installing hole 1, buckle 22 and slot 23 are arranged around installing hole 1.And slot 23 is two and is arranged in buckle 22 both sides.The length direction of the axis of the first convex lens 31 and light conductor 3 is an obtuse angle.The rear end face of the 3rd convex lens 33 offers groove 39, and this groove 39 forms incidence surface.
Shown in Fig. 4 and Fig. 5, light conductor 3 comprises connecting portion 34 and takes shape in successively from front to back the first convex lens 31, the second convex lens 32 and the 3rd convex lens 33 on connecting portion 34, the front end face of the first convex lens 31 has exiting surface, the rear end face of the 3rd convex lens 33 has incidence surface, and the outside of connecting portion 34 forms draw-in groove 37 and positioning bar 35.Connecting portion 34 indents form a built-in groove 341, front end projection one back-up block 38, the second convex lens 32 and the 3rd convex lens 33 take shape in this built-in groove 341 and expose end, and the first 31, convex lens take shape on back-up block 38, and these back-up block 38 roots are formed with shoulder portion 36.
