Description
Technical field
The present invention relates to a kind of remote controler, in particular to a kind of remote controler navigation keys.
Background technique
With the development of industrial technology with innovation, consumer increasingly payes attention to user experience, now individually leads on a remote control
The backlight effect of boat button is single region, without that can show the knot of two different backlight areas respectively in different modes
Structure.For example, the key up and down of the navigation button can realize navigation feature, left and right press key is wished after entering specific Video Applications
F.F., rewind function can be achieved, technically realized the function, can corresponding backlight area independently to light function also unreal
It is existing, e.g., on key it is equipped with two backlight areas, when navigation, pressing the navigation button can realize the backlight lightening of periphery, when F.F., fast
When moving back, pressing the navigation button can realize the backlight lightening of inside.Or for different user demands, the same button is pressed,
Need to determine the control model of remote controler by different backlight lightening modes, in the prior art for user demand so
There is no similar technical solution.
Summary of the invention
The object of the present invention is to provide a kind of remote controler navigation keys structures with separate backlight region, it can be achieved that individually pressing
Button lights the scheme in two separate backlight regions.
The object of the present invention is achieved like this: a kind of remote controler navigation keys structure with separate backlight region, including
Rear cover, pcb board, metal dome, conducting resinl and the front cover being stacked from the bottom to top, be provided on the front cover navigation by
Button, four angles of the navigation button as four function buttons, described the navigation button include shell made of non-transparent material and
Inner casing made of the transparent material of interior of shell is set, be located on the shell function button region offer the first loophole and
Second loophole, the first loophole inside is corresponding to offer the first type chamber, and correspondence offers second type chamber inside the second loophole,
Mutual optical isolation between first type chamber and second type chamber, the inner casing are divided into the first inner casing and the second inner casing, are separately positioned on
One type chamber and second type are intracavitary, and the conducting resinl below the navigation button is divided into the first conducting resinl and the second conducting resinl, the first conducting resinl
It is set in the second conducting resinl periphery, and forms optical isolation between each other, is corresponding with below the first conducting resinl and the second conducting resinl solely
Light source is found, the button portion of corresponding function key, the enclosure bottom below function button region are provided on first conducting resinl
It is fitted in the button portion with the first inner casing bottom surface, the boss with the cooperation of second type chamber is machined on second conducting resinl,
The boss protrudes into the setting of second type chamber and fills up second type chamber, and its top surface is fitted on the second inner casing bottom surface, and first is conductive
Impermeable light processing is done on glue and the second conducting resinl surface except the base, and first conducting resinl and the first inner casing fit area are done
