Light-leaking-preventing instrument pointer structure

Abstract

The invention discloses a light-leaking-preventing instrument pointer structure comprising a pointer shaft, a pointer body and a cap cover. The pointer body extends from one end of the pointer shaft and comprises an upper light guide surface and two side light guide surfaces which are arranged at the two sides respectively. The cap cover is provided with two notch edges and a through hole which is arranged between the two notch edges. At least a part of the two notch edges is utilized to cover the upper light guide surface of the pointer body so that the light leaking situation of the pointer body can be reduced.

Description

technical field [0001] The invention relates to a light-leakage-proof instrument pointer structure, in particular to a light-leakage-proof instrument pointer structure in which light is directly irradiated on the pointer for luminous display. Background technique [0002] In the existing technology, various automobiles and motorcycles use instruments to display driving speed, gasoline consumption, vehicle temperature and other indications, so as to clearly identify the state of the vehicle. The instrument can clearly see the position indicated by the pointer during the day or in a place with sufficient light, but at night or in a dark place, it needs the assistance of light to clearly see the position indicated by the pointer on the instrument. [0003] like figure 1 , 2 As shown, it is an existing light-emitting structure of an instrument, including a base 11, an instrument panel 12, a light-emitting element 13, a pointer 14, a cap 15 and a motor 16, wherein the light-emi...

Problems solved by technology

[0004] However, since the pointer 14 and the cap 15 are engaged with each other, as figure 2 As shown, it is easier to generate a gap between the pointer 14 and the cap 15. When the light emitting element 13 is lit, the light source of the light emitting element 13 will leak through the gap between the pointer 14 and the cap 15, thus causing the The problem of light leakage of the pointer 14; in order to overcome the above problems, the manufacturer usually processes and coats a color coating on the upper surface 141 and the two side surfaces 142 of the pointer 14 to reduce the light leakage of the pointer 14

However, since the color coating must be coated on the upper surface 141 and the two side surfaces 142 at the same time, the effect of light leakage can be reduced, so the manufacturing hours and production cost of the pointer 14 are relatively increased.
