Wheel Module for Mouse Devices

Abstract

The invention discloses a roller module applied to a mouse device. The roller module comprises a fixed base, a swing base and a roller, wherein the swing base can be installed on the fixed base in the mode of swinging up and down relative to the fixed base through a rotary shaft, the roller is installed on the swing base in the mode of rotating relative to the swing base, a pressing plate is arranged at the bottom side of the swing base, and when the roller is pressed by force, the swing base is driven to rotate by a predetermined angle relative to the fixed base, and the pressing plate is made to press a microswitch of the mouse device. The strength of a user pressing the roller can be directly transmitted to the pressing plate below the swing base through the swing base moving relative to the fixed base, then the microswitch is pressed, the roller of a mouse can be easily pressed, and therefore the roller module is easier to use and saves more effort.

Description

technical field [0001] The invention relates to a wheel module, which is applied to a mouse device, in particular to a wheel module which is convenient for a user to press the wheel. Background technique [0002] A mouse device and a keyboard are common input devices in computer equipment, and are used to move a cursor position on a screen or to type. [0003] A mouse device is usually configured with a left button, a right button and a scroll wheel. When users browse the contents of files on the screen, such as text files, spreadsheets, graphic files or web pages, etc., sometimes it is necessary to adjust the boundary range or size displayed on the screen. At this time, use the scroll wheel on the mouse device to achieve the above purposes. The wheel module in the prior art generally includes a wheel and a detector for detecting the rotation state of the wheel. Generally speaking, the scroll wheel is usually assembled in the housing of the mouse and partially exposed to ...

AI Technical Summary

Problems solved by technology

However, in the existing mouse device, the micro switch is generally arranged on the side of the scroll wheel, which requires a lot of force when pressing the scroll wheel, and the scroll wheel must be tilted when pressed.

Therefore, the mouse wheel is more laborious to use, and the tilted mouse wheel also makes the rotation and scrolling of the mouse wheel unable to be precisely controlled
