Abstract
The invention relates to a knob, which comprises a knob cover cap with an indicating lamp window, a circuit board positioned behind the cover cap, a light source fixed on the circuit board and a light guide column fixed on the cover cap, wherein the light guide column is fixed in the cover cap; the light emergency surface positioned at one end of the light guide column is opposite to the indicating lamp window; the other end of the light guide column extends to the circuit board; the light incidence surface of the light guide column is opposite to the light source; the light source is positioned on the rotary central line of the cover cap; and when the cover cap rotates, the light guide column rotates along with the cover cap, and the light incidence surface of the light guide column is always opposite to the light source. The knob only adopts one light emitting diode (LED) lamp and is not limited by the gear limitation of a positioning encoder; the knob has a simple structure and is low in cost; and the knob can be applied to any controller required to adopt a positioning function.
Description
Technical field
The present invention relates to knob, relate in particular to the knob with indicating knob current state backlight or gear.
Background technology
The knob of existing use indicating knob current state backlight or gear generally comprises the lid with transparent window, gear place corresponding under lid all can have corresponding pointing character to indicate residing gear, LED lamp is all set under each gear, when lid rotates, we just can see the pointing character being illuminated by the LED lamp of respective notch by transparent window.This structure need to adopt a plurality of LED lamps, and cost is higher.Also having a kind of mode is on position encoder, to configure LED lamp (LED quantity is consistent with numbers of gear steps), and cost is also higher, and structure is also complicated.
Summary of the invention
Based on this, be necessary to provide a kind of knob simple in structure, with low cost.
A knob, it comprise be provided with pilot lamp window knob block, be positioned at wiring board after block and fixing light source in the circuit board.Described knob also comprises the light-guiding pillar being fixed on block, and one end of described light-guiding pillar bright dipping is fixed in described block and pilot lamp window opposite position, and remainder is outside described block, and it is relative with light source that wiring board is stretched in light inlet one end of light-guiding pillar; Described light source is for being positioned on block rotation centerline; When block rotation, light-guiding pillar is with block rotation, and the incidence surface of light-guiding pillar is relative with light source all the time; On described wiring board, have deep-slotted chip breaker, described light source fixing in the circuit board with the opposing side of block, described light-guiding pillar is just relative with light source through its incidence surface after deep-slotted chip breaker.
In a preferred embodiment, described light-guiding pillar is L-type substantially.
Knob of the present invention only adopts a LED lamp, and is not subject to the constraint of position encoder gear restriction, and simple in structure, cost is low.So long as can adopt knob of the present invention above need to adopting the controller of positioning action.
Accompanying drawing explanation
Fig. 1 is the front view of the knob of an embodiment.
Fig. 2 is the A-A cut-open view of the knob of Fig. 1.
Fig. 3 is the explosive view of the knob of Fig. 1.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, knob of the present invention is described in further detail.
As shown in Figure 1 to Figure 3, in an embodiment, knob of the present invention mainly comprises knob block (hereinafter to be referred as block) 10, be positioned at wiring board 20 after block, be fixed on the light source 30 on wiring board 20 and be fixed on the light-guiding pillar 40 on block 10.One of them knob only needs to arrange a light source.Preferably, light source adopts LED lamp.
Block 10 is rotary symmetrical lid substantially, and it is fixed on the housing of equipment conventionally movably, and wiring board 20 is fixed in apparatus casing.The gear sign of knob can be arranged on apparatus casing, also can be arranged on the on-rotatably moving part (parts that do not rotate with knob) of knob.The rotation centerline of block 10 is through light source 30.On block 10, be provided with indication window 12.This indication window 12 can be the visual windows that transparent material is made, and also can be formed in the opening on block.In block 10, be formed with one for accommodating the host cavity of light-guiding pillar 40, this host cavity is from the through indication window 12 of block opening.
In the present embodiment, light-guiding pillar 40 is L-type substantially, or is roughly shorter U-shapedly on one side, and its xsect can be the arbitrary shapes such as circle, square, triangle.The first end of light-guiding pillar 40 is formed with incidence surface, and its second end is formed with exiting surface.Light-guiding pillar 40 is fixed on block 10, and its second end stretches in host cavity, and its exiting surface is near (indication window is visual windows or opening) or stretch out (indication window is opening) indication window 12.The first end of light-guiding pillar 40 stretches to wiring board 20, and its incidence surface is relative with light source 30.
In the present embodiment, in order to reduce the whole height of knob, on wiring board 20, have deep-slotted chip breaker 22.Light source 30 is fixed on wiring board 20 sides opposing with block 10.Light-guiding pillar 40 is through deep-slotted chip breaker 22 bendings, thereby the incidence surface of its first end is just relative with light source 30.When 10 whens rotation of block, light-guiding pillar 40 is with block 10 in the interior movement of deep-slotted chip breaker 22, and the incidence surface of light-guiding pillar 40 is relative with light source 30 all the time, thus by the light conduction of light source 30 to blocking a shot 10 indication window 12, be knob indication rotation status.
In other embodiment, light-guiding pillar can be substantially S-type, or the repeatedly bending shape of approximate S type, is arranged between wiring board and block and realizes leaded light.Corresponding, light source is fixed on wiring board towards the one side of block.The height of the knob of this structure is higher compared with above-described embodiment.
To sum up, the present invention utilizes a light source that is arranged on knob rotation center and light-guiding pillar being fixed on block to realize the function of indicating knob current state or gear, no matter knob still turns clockwise counterclockwise, incidence surface and the light source relative position that all can guarantee light-guiding pillar are constant, and indication window can be thrown light in knob rotary course always.Knob of the present invention have advantages of be not subject to position encoder gear restriction constraint, simple in structure, cost is low.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
