USER-INTERFACE ASSEMBLY AND METHOD FOR INTEGRATING TOUCH ASSEMBLY INTO USER-INTERFACE ASSEMBLY

WIPO Patent Application WO/2018/195684

A1

A user-interface assembly disclosed herein comprises: a supporting frame (1); a part for providing a switch function to the user-interface assembly and to be received in a recess formed in the supporting frame (1); and an overlay (5) for covering and adhering to an upper surface of the supporting frame (1) and an upper surface of the part by a back adhesive (8) when the part is received in the recess; wherein a transition zone (11, 24) is provided around the part under the overlay (5), which transition zone extends at least from a sidewall of the recess toward the part such that the overlay (5) can smoothly transit from the upper surface of the supporting frame (1) to the upper surface of the part. Also disclosed herein is a method for integrating a touch assembly (3) into a user-interface assembly, the touch assembly (3) having a top surface and a bottom surface, the user-interface assembly having a supporting frame (1) and a recess for receiving the touch assembly (3), and the method comprising: placing the top surface of the touch assembly (3) on a flat table (26); positioning the supporting frame (1) at a predetermined position relative to the touch assembly (3) such that at least one portion of the touch assembly (3) is located within the recess; and injecting a flowable adhesive (28) into a gap between the portion of the touch assembly (3) and a corresponding portion of the recess from a direction of a bottom of the supporting frame (1) to fix the touch assembly (3) onto the supporting frame (1),, so that an amount of the injected flowable adhesive can be adapted according to a different volume of the gap. According to the present invention, a flat design of a user-interface assembly can be achieved in a cost effective manner.
