  • Patent number: 11797106
    Abstract: A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes an actuating screw and a stopper. The actuating screw is screwed into the stopper. While the actuating screw is rotated in response to a rotational force, the actuating screw is moved in a screwing manner, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by a first stopping part of the stopper, the keycap is switched from the pressable state to a non-pressable state.

  • Patent number: 11784013
    Abstract: A mouse device includes a casing and plural key modules. The plural key modules are installed on two opposite sides of the casing. Each key module includes a switch, an elastic element, a keycap and a stopper. The switch and the elastic element are disposed within the casing. The keycap is detachably connected with the elastic element. The elastic element is arranged between the keycap and the switch. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved in a direction toward the switch and the elastic element is moved with the keycap, so that the switch is triggered by the elastic element. The stopper is detachably connected between the keycap and the elastic element. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.

  • Patent number: 11614807
    Abstract: A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes a movable block, a push block and a stopper. While the movable block is pushed and moved in response to a pushing force, the push block is correspondingly moved. While the push block is moved, the stopper is pushed by the push block, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.
