Title:
PIEZORESISTOR MULTI-DIRECTION INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/063522
Kind Code:
A1
Abstract:
A piezoresistor multi-direction input device, comprising an upper cover (2), a base (1), a rocker module (3), a reset module (4), an electrical module (5) and a terminal module (6). A conducting elastic member (53) of the electrical module (5) is installed at the upper cover (2). The base (1) and piezoresistor (51) surround and thus form a cavity, in which an operation rocker (31) causes an eccentric wheel (30) of an upper rocking arm (32) or lower rocking arm (33) to rotate. The eccentric wheel (30) changes height in an axial direction, causing the elastic member to deform variously, thereby causing the surface of the piezoresistor (51) to receive various pressures, and causing the piezoresistor (51) to output various resistance values, realizing control of a screen cursor. By providing a structure in which the rocking arm seat (34) or base (1) structure is adapted to the upper rocking arm (32) and lower rocking arm (33), the rocker (31) has a simple structure, is easily assembled, has a good touch pressure feel, and by providing the eccentric wheel (30) integrated with the upper rocking arm (32) and lower rocking arm (33), various pressures and resistances can be realized, thereby realizing rocker operations in more directions, and display of a wide range of cursor brightnesses, improving user experience.
