Abstract
Systems and methods are disclosed for a lock assembly having a touchscreen. The lock assembly includes an interior assembly and an exterior assembly having an exterior lock housing and a touchscreen assembly. The touchscreen assembly includes a touchscreen having selectable icons on a front surface thereof, a printed circuit board assembly (PCBA), and a support structure. The PCBA includes input regions corresponding to the selectable icons and light emitters. The support structure is configured to reflect light emitted from the light emitters through the front surface of the touchscreen.
Claims27
A lock assembly comprising:
- an interior assembly and an exterior assembly, the exterior assembly comprising an exterior lock housing and a touchscreen assembly, the touchscreen assembly comprising:
- a touchscreen having a plurality of selectable icons on a front surface of the touchscreen;
- a printed circuit board assembly (PCBA) comprising:
- a plurality of input regions, each input region corresponding to one of the plurality of selectable icons;
- a plurality of light emitters positioned on the PCBA;
- and
- a plurality of PCBA windows defined through the PCBA, each of the plurality of PCBA windows being positioned adjacent to a corresponding one of the plurality of light emitters;
- and
- a support structure facing the plurality of light emitters on the PCBA and on an opposite side of the PCBA than the touchscreen, the support structure having a plurality of icon cavities, each of the plurality of icon cavities configured to reflect light emitted from the plurality of light emitters through the front surface of the touchscreen;
- wherein the plurality of icon cavities are aligned with the plurality of PCBA windows such that light reflected by the support structure passes through the PCBA.
A touchscreen assembly comprising:
- a touchscreen having a plurality of selectable icons on a front surface of the touchscreen;
- a printed circuit board assembly (PCBA) comprising:
- a plurality of input regions, each input region corresponding to one of the plurality of selectable icons;
- a plurality of light emitters positioned on the PCBA;
- and
- a plurality of PCBA windows defined through the PCBA, each of the plurality of PCBA windows being positioned adjacent to a corresponding one of the plurality of light emitters;
- and
- a support structure facing the plurality of light emitters on the PCBA and on an opposite side of the PCBA than the touchscreen, the support structure having a plurality of icon cavities, each of the plurality of icon cavities structured to reflect light emitted from the plurality of light emitters through the front surface of the touchscreen, the plurality of light emitters positioned between the touchscreen and the support structure;
- wherein the plurality of icon cavities is aligned with the plurality of PCBA windows such that light reflected by the support structure passes through the PCBA.
A lock assembly comprising:
- an interior assembly and an exterior assembly, the exterior assembly comprising an exterior lock housing and a touchscreen assembly, the touchscreen assembly comprising:
- a touchscreen having a plurality of icons on a front surface of the touchscreen;
- a printed circuit board assembly (PCBA) having a front face directed toward the touchscreen and an opposite rear face directed away from the touchscreen, the PCBA including a plurality of PCBA windows;
- a plurality of light emitters positioned on the rear face of the PCBA, each of the plurality of light emitters being positioned adjacent to a corresponding one of the plurality of PCBA windows;
- and
- a support structure facing the rear face of the PCBA, the support structure having a plurality of icon cavities, each of the plurality of icon cavities structured to reflect light emitted from the plurality of light emitters toward the front surface of the touchscreen;
- wherein the plurality of icon cavities is aligned with the plurality of PCBA windows such that light reflected by the support structure passes through the PCBA.
