Touchpad device

A touchpad device comprises a base plate, at least one support plate, a circuit board, a first extension structure and a second extension structure. The base plate is configured to be secured to the housing. The support plate is coupled to the bottom plate and is configured to swing relative to the bottom plate. The circuit board is attached to the side, away from the bottom plate, of the supporting plate. The first extension structure is arranged on the bottom plate and extends towards the supporting plate. The second extension structure is provided with the supporting plate and extends towards the bottom plate. The first extension structure partially extends to the side, close to the supporting plate, of the second extension structure, or the second extension structure partially extends to the side, close to the bottom plate, of the first extension structure. 一种触控板装置，包含底板、至少一支撑板、电路板、第一延伸结构以及第二延伸结构。底板配置以固定至壳体。支撑板耦接底板，并配置以相对于底板摆动。电路板贴附至支撑板远离底板的一侧。第一延伸结构设置于底板，并朝向支撑板延伸。第二延伸结构设置支撑板，并朝向底板延伸。第一延伸结构部分地延伸至第二延伸结构靠近支撑
