Touchpad device

Abstract

A touchpad device includes a substrate, a circuit board, a connection plate, a resilient member, a triggering member, a first balance bar, a second balance bar, a first swing plate, and a second swing plate. The circuit board is disposed above the substrate and includes a trigger switch. The connection plate has a hollow hole corresponding to the trigger switch. The resilient member is disposed between the substrate and the circuit board. The triggering member corresponds to the hollow hole. The first balance bar is disposed between a first side of the connection plate and the substrate, and the second balance bar is disposed between a second side of the connection plate and the substrate. The swing plates are disposed between the substrate and the circuit board and are pressable to move with respect to the substrate, thereby driving the triggering member to move toward the trigger switch.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This non-provisional application claims priority under 35 U.S.C. § 119(a) to Patent Application No. 110117178 filed in Taiwan, R.O.C. on May 12, 2021, the entire contents of which are hereby incorporated by reference.BACKGROUNDTechnical Field

[0002] The instant disclosure relates to an input device, in particular, to a touchpad device.Related Art

[0003] Touchpads are common input devices widely applied in computers. The touchpad is provided for sensing the movement or pressing of a user's finger(s) to control the cursor to perform an action (e.g., to move, to click, or the like).SUMMARY

[0004] A touchpad known to the inventor has a touchpad and a substrate. The touchpad has a pivot side, and the touchpad is pivotally fixed on the substrate through the pivot side. When a portion of the touchpad away from the pivot side is pressed, the touchpad swings downwardly with respect to the substrate by taking the pivot side as the swing axis so as to gene...
