Abstract

The invention discloses a vehicle knob structure. In cooperation with a decoder and lamplight, the vehicle knob structure is convenient to manipulate and emits light with uniform brightness and color. The vehicle knob structure resolves problems of unevenness of t brightness and color of a light ring of a key and unevenness of brightness and color of laser engraving, and prevents lamp positions arranged on a circuit board from being seen from the exterior of the key. The vehicle knob structure can be universally used as any vehicle knob key, such as knob keys of instrument controllers, knob keys of sound system controllers, knob keys of air conditioning controllers, and knob keys in vehicles.

Description

A kind of automobile-used knob key structure

Technical field

This product is the design of knob outward appearance and background illumination structure in a kind of automobile-used control panel.The instrument of this structure is backlight to be applicable to automobile instrument, automobile controller, any need and to use the fields such as the motor vehicle of background illumination knob, household electrical appliances, instrument, equipment.

Background technology

In current automobile-used control panel, the application of knob is because effect is direct, be easier to intuitive operation, and more and more adopted by depot, but the background illumination effects of knob does not also arrive optimized degree, mainly be limited by the structural design of knob below and the design of electronic circuits of part electrical equipment, due to the blocking or interfere of structure, cause the required demonstration character in knob button surface to occur the more unequal undesirable conditions of light and shade, the still domestic solution without maturation.For this kind of situation, we hereby develop and are applicable to the knob backing structure that general automobile is used, and to overcome brightness disproportionation, improve the utilization factor of light source, reduce light loss.

Summary of the invention

Disclosed by the invention is a kind of automobile-used knob structure, comprise even photochromic ring, knob main body, the transparent ring of light, described even photochromic ring is coordinated and is embedded in knob main body by machinery, the described transparent ring of light is contained in knob body interior by physical construction, what described even photochromic ring adopted is a kind of printing opacity but opaque material, described agent structure be also adopt a kind of printing opacity but opaque material, in described agent structure, have laser radium carving character to show, what the described transparent ring of light adopted is a kind of transparent material.

Disclosed by the invention is a kind of automobile-used knob structure, by with the coordinating of demoder and light, can make operation more convenient, and brightness, the color of the light that sends are more even; Solve aperture brightness, color inhomogeneous of button, also solved the inhomogeneous of the brightness of laser radium carving, color, avoided can seeing in the outside of button the lamp position of arranging on circuit board; The present invention can be common to any automobile-used knob button, comprises the various knob buttons in instrument controller, acoustic controller, air-conditioner controller and car.

Accompanying drawing explanation:

Fig. 1 is a kind of automobile-used knob key structure figure.

Accompanying drawing is indicated list:

1, even photochromic ring 2, knob main body 3, the transparent ring of light

4, light emitting diode 5, circuit board 6, demonstration character

7, potentiometer or scrambler

specific embodiments:

Specific embodiments:

Design respectively even photochromic ring, knob main body and the transparent ring of light by computer three-dimensional software;

Make respectively even photochromic ring mould, knob body die and transparent ring of light mould;

Utilize even photochromic ring mould and the even photochromic shaped part of material injection moulding, utilize knob body die and material injection moulding knob body element, utilize the transparent smooth part of transparent ring of light mould and material injection moulding;

Knob main body radium carving character is produced;

First even photochromic ring is fit into knob main body from knob main body top, the more transparent ring of light is fit into knob main body from knob main body below.

Through custom-designed structure, knob can be broken the normal procedure in design.From design level, need not too much scruple structure limitation, character is put and can be broken through routine, increases feeling of freshness and modern sense, and can knob shaped also can be designed as abnormity, and at all need not consider reach designing requirement in volume production process.

Traditional knob backing structure is to allow single LEDs act under the vertical projection character of each knob, and because LED is pointolite, and brightness is comparatively concentrated, easily in pattern, leaves " hot spot " that be commonly called as, the i.e. situation of brightness irregularities; This situation, because structure is limited, therefore cannot effectively improve, only has the LED of increasing quantity to improve hot spot number, inhomogeneous to cover.Under the objective condition of miniaturization, not there is redundant space to put more LED, so the present invention passes through physical arrangement, the pointolite of LED is become to discrete light source through some particles generation refractions and reflection effect in the process structure of particular design, thereby effectively improve uniform properties at arrival sensitive surface.

Claims

1. this automobile-used knob key structure, is made up of knob, the ring of light, illuminating source; Main body is the structure that there is the trough of belt of silk-screen character on a surface, and top is equipped with an even photochromic ring with buckle, and agent structure inside has groove and is effectively connected with scrambler or potentiometer; Lower floor's luminous component of agent structure is light emitting diode and the transparent even ring of light, and all devices below agent structure are assemblied on circuit board.

2. according in this automobile-used knob key structure described in right 1, knob main body coordinates with the form of draw-in groove with buckle with even photochromic ring.

3. according in this automobile-used knob key structure described in right 1, what the color of even photochromic ring can be according to people need to select different colors.

4. according in this automobile-used knob key structure described in right 1, the mode that light reflects by twice even light and knob main body inner wall, reduce the limitation due to lumination of light emitting diode angle, the bright blackening that the vision of bringing demonstrates, makes the effect showing reach more even.
