Problems solved by technology

[0007] However, since the light is refracted by the light emitting part and then attenuated in the process of spreading toward the tip of the pointer, the brightness of the illuminated area is uneven.
Especially when the instrument panel is not in a regular shape, for example, when a "コ"-shaped instrument panel is adopted, during the movement of the pointer, the distance from the part on the instrument panel that is expected to be illuminated to the center of rotation is in a state of constant change, thus The problem of uneven brightness is more obvious, thus affecting the visibility of the instrument panel

Embodiment Construction

[0076] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0077] The pointer instrument panel 1 of the present invention is, for example, a tachometer mounted on a vehicle such as an automobile or a two-wheeled vehicle, and the rotation speed of the engine mounted on the vehicle is indicated by the rotation of the pointer, thereby notifying the user (driver) of the tachometer. Know the engine speed.

Abstract

The invention relates to a dashboard structure. The dashboard structure is provided with a character panel located at a dashboard dial side, a pointer driven to rotate by a driving portion, a housingfor mounting the pointer, and a light source for illumination; the character panel is provided with a light-transmitting belt; an indication portion representing measurements is formed on the light-transmitting belt; the pointer indicates the measurements of the indication portion; the pointer is provided with a light shielding portion; seen from the dashboard dial side, the light shielding portion extends along the length direction of the pointer and covers one side of the rotation direction of the pointer; the light shielding portion is used for shielding light emitted from one side of the rotation direction of the pointer; one side of the pointer, which is shielded by the light shielding portion, is p provided with a refracting portion; the refracting portion is located between the rotation center of the center side of the pointer and the front end of the pointer in the length direction of the pointer; and the refracting portion refracts the light from one side of the pointer whichis shielded by the light shielding portion to one side of the pointer which is not shielded by the light shielding portion. With the dashboard structure adopted, light emitted from the light source can be fully utilized, and optimal observation performance can be ensured with the intensity of the light source not required to be strengthened.

Description

technical field [0001] The invention relates to a pointer instrument panel structure, in particular to a pointer instrument panel structure with lighting function. Background technique [0002] Conventionally, as such an analog meter panel structure, for example, an analog meter (speedometer) described in Patent Document 1 below is known. [0003] This type of pointer speedometer has: a dial with a gauge scale, a transmissive pointer that rotates in accordance with the speed, a drive unit that drives the pointer to rotate, a light source for lighting the pointer, a housing for mounting the pointer, and A circuit board with a control unit. [0004] Figure 11 is the main view of the prior art pointer, Figure 12 will be Figure 11 Shown is the front view of the pointer assembled on the case. [0005] Such as Figure 11 , Figure 12 As shown, the pointer 300 includes a pointer base 302 installed on the instrument panel housing 400, an indicating part (pointer body) 301 ins...
