Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model display knob is described in further detail.
Display knob of the present utility model is particularly useful for the knob backing structure of automobile, the display knob of such as automobile audio.
As shown in Figures 1 to 4, in a preferred embodiment, display knob of the present utility model comprises knob body, LCD display, reflection shield, LED, scrambler and circuit board.Wherein, LED, scrambler and LCD display all realize being electrically connected with circuit board.Scrambler, by opto-electronic conversion, converts the mechanical quantity such as angular displacement, angular velocity of display knob to corresponding electric pulse with digital output to LCD display, is shown by LCD display.
Knob body comprises transparency cover and knob shell.The wherein roughly rounded sheet of transparency cover, transparency cover adopts the PC material of all-transparent to make.Knob shell comprises the circular open that is tightly connected with transparency cover and the groove structure under shed.
Reflection shield comprises reflection wall and bracing frame.Reflection wall is the madial wall of reflection shield.Reflection wall is formed with the cavity of up big and down small truncated cone-shaped.LED is positioned at the circle center of the under shed of this cavity.The upper shed of the cavity of reflection wall is positioned at the below of LCD display.Therefore, as shown in Figure 3, the light that LED is launched converges after the reflection wall reflection of reflection shield, then exposes to LCD display, makes LCD display display setting content.Converge by arranging the pointolite light beam of reflection shield to LED, expose to LCD display again, therefore, when reaching the display effect of LCD display, can save the power consumption of LED, namely more low power LED also can reach and make the better display effect of LCD display, and LCD display printing opacity can be made even by the optically focused of reflection wall, can not produce hot spot, display effect is better, strengthens Consumer's Experience.Annular outer edge is extended to horizontal direction in the upper shed of reflection wall.Bracing frame is formed as cylindric.The annular outer edge of reflection shield wall is fixedly connected with the top of the inwall of bracing frame.Bracing frame is set in the periphery of reflection wall, can effectively fixes and protect reflection wall.
LCD display is arranged at below transparency cover.Annular sidewall is extended downwards in the periphery of transparency cover, and the upper end of bracing frame is embedded in annular sidewall.Meanwhile, because transparency cover and knob enclosing cover are tightly connected, therefore, the parallel rays of light after reflection shield reflection that LED is launched can not be emitted to the place beyond transparency cover, and the edge of transparency cover there will not be the ring of light, thus there will not be the phenomenon of light leak.
Also optical filter is provided with in the below of LCD display.Optical filter is placed or is fixed in the annular outer edge of reflection shield.Optical filter is set in LCD display bottom surface, the light of LED light line after reflection shield reflection, then mating plate is just mapped to LCD display after filtration, light can be made more even, strengthen the display effect of LCD display.
The top of scrambler is embedded in knob shell, thus namely produces different output signals by scrambler by rotating knob shell, thus LCD display shows different displaying contents.Wherein, the lower limb of knob shell is provided with multiple buckle.Be provided with on the top of the periphery of scrambler and the multiple snap-fit be clasped.Therefore, adopt buckle and snap-fit that the connection between knob shell and scrambler can be made more firm, reduce display knob rocking in rotary course.Knob shell and scrambler are formed with a container cavity, and reflection shield, bracing frame are all contained in this container cavity, thus make the compact conformation showing knob, can save the space of display knob, reduce the volume of display knob.
Display knob of the present utility model adopts LCD display, the displaying contents of LCD display can free setting as required, and ceaselessly convert displaying contents in the process that can rotate at display knob, therefore, do not need the display area strengthening display knob that the displaying contents of display knob can be made more rich and varied; On the other hand, reflection shield is provided with between LCD display and LED, the light launched as the LED of pointolite converges after the reflection wall reflection of reflection shield, be irradiated to LCD display again, content in LCD display is shown, reflection shield is set and enables the light exposing to LCD display make LCD display printing opacity even, can not hot spot be produced, display effect is better, strengthens Consumer's Experience.
In preferred embodiment, display knob of the present utility model is applied to automobile audio.The display circuit board of knob is connected with the main frame of automobile audio, and after the main frame of automobile audio is energized, the light of the transmitting of LED reflexes to LCD display through reflection shield, and user can pass through transparency cover and sees displaying contents in LCD display.Can utilize the broadcasting of LCD display display automobile sound equipment, stopping and volume status, thus user more clearly can obtain the information such as broadcasting and volume of current sound equipment.
Although carry out in conjunction with above specific embodiment description of the present utility model, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all like this substitute, improve and change be all included in the spirit and scope of attached claim.
