Abstract
The utility model relates to a light-leakage preventing structure for motormeter hands, which consists of a meter frame, a dial, a hand light shading component, a hand light transmitting component and a hand cap. The dial is arranged on the meter frame; the light transmitting component is provided with a coupling shaft; the meter frame is provided with a shaft hole, and the coupling shaft is arranged in the hole; the light shading component is in cylindrical tubular shape and sleeved outside the coupling shaft; the outer circumference of the upper end of the light shading component is provided with an annular step; the hand cap is sleeved outside the light transmitting component and the light shading component; the lower end of the hand cap extends to the dial, and the inner wall of the extending part of the hand cap, the lower side of the annular step and the outer wall of the light shading component form an reverse U-shaped annular groove; the meter frame around the upper end of the shaft hole is provided with an annular boss which extends upward to the annular groove. The annular groove and the annular boss form a C-shaped gap so as to prevent light leakage. Therefore, light leakage halo on the dial is effectively prevented, which is convenient for users to observe.
Description
Technical field:
The utility model relates to physical field, relates in particular to auto meter, particularly a kind of anti-light leakage structure of automobile meter pointer.
Background technology:
In the instrument of middle-to-high end car, more clear for instrument is shown behind bright lamp, need prevent that the light of light source from spilling forward from the instrument carrier panel rear.Light leak often takes place down in the pointer cap of instrument, forms tangible halation at instrument carrier panel, influences the display resolution and the contrast ratio of instrument.In the prior art, a circle boss is set on the instrument framework, injects in the pointer cap, be used for preventing light leak, but still have part light to arrive on the instrument carrier panel by the reflection of pointer shading piece and pointer light guide.
Summary of the invention:
The purpose of this utility model is to provide a kind of anti-light leakage structure of automobile meter pointer, and the anti-light leakage structure of described this automobile meter pointer will solve in the prior art reflection by pointer shading piece and pointer light guide of light behind the Automobile instrument and arrive on the instrument carrier panel, influences the display resolution of instrument and the technical matters of contrast ratio.
The anti-light leakage structure of this automobile meter pointer of the present utility model is by the instrument framework, dial plate, the pointer shading piece, pointer light guide and pointer cap constitute, described dial plate is arranged on the instrument framework, described pointer light guide is provided with a coupling rod, be provided with the axis hole that cooperates with described coupling rod in the described instrument framework, coupling rod is arranged in the described axis hole, wherein, described pointer shading piece is cylindrical tube, the pointer shading piece is set in the outside of coupling rod, the upper end excircle of pointer shading piece is provided with circular step, described pointer cap sleeve is located at the periphery of pointer light guide and pointer shading piece, extend to described dial side the lower end of pointer cap, the inwall of pointer cap lower end extension, the outer wall of the downside of described circular step and pointer shading piece constitutes the circular groove that the cross section is inverted U, the instrument framework of end periphery is provided with annular boss on the axis hole, and described annular boss extends up in the described circular groove.
Further, the inwall of axis hole bottom is provided with the ring-type inner convex platform, and described ring-type inner convex platform is positioned at the below of pointer shading piece lower surface.
Further, the inside and outside wall of the outer wall of the downside of the inwall of pointer cap lower end extension, described circular step, pointer shading piece and annular boss is provided with and eliminates reflecting surface or eliminate reflectance coating.
Principle of work of the present utility model is: the outer wall of the inwall of pointer cap lower end extension, the downside of circular step, pointer shading piece and the inside and outside wall of annular boss cooperate formation C type gap, thereby avoid light leak.The ring-type inner convex platform of axis hole bottom can prevent that light from passing through from the outer wall of pointer shading piece lower end simultaneously.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model utilizes the downside of the inwall of pointer cap lower end extension, circular step, the outer wall of pointer shading piece and the inside and outside wall of annular boss to cooperate formation C type gap, thereby avoids light leak.The ring-type inner convex platform of axis hole bottom can prevent that light from passing through from the outer wall of pointer shading piece lower end simultaneously.Effectively prevent the light leak halation on the dial plate, increased the display resolution and the contrast ratio of auto meter, made things convenient for the user to observe.
