Description

Roller module, mouse device and input device Technical Field The present utility model relates to a roller module, a mouse device, and an input device, and more particularly, to a roller module, a mouse device, and an input device for controlling an input device to perform user-defined input operations according to a rotation angle detection result of a rotation sensor. Background With the progress and development of technology, computers have been widely used in every person's daily life. In the current usage habit of a personal computer, a mouse is one of the indispensable input devices, for example, a user can rotate a wheel (e.g. by toggling a finger) to implement a corresponding input operation, such as scrolling a web page. However, the above design cannot allow the user to adjust the corresponding relationship between the rotation angle of the roller and the display screen operated by the input device, so as to limit the flexibility and convenience of the mouse. In addition, in practical application, in order to enable the user to effectively control the rotation degree of the roller, a paragraph sense mechanism is usually arranged in the mouse to provide paragraph sense for the rotation of the roller in stages, and the user can feel the paragraph sense when the roller rotates through finger touch, so that the actual rotation angle of the roller is controlled. The conventional paragraph sense mechanism for the mouse mostly generates paragraph sense through contact interference among internal components of the mouse, but after the mechanism is designed to be used for a period of time, the internal components of the mouse are worn out due to frequent contact interference, so that the mechanism cannot generate expected paragraph sense and fails; in addition, since the number of the internal components of the mouse for generating the segment feeling is too large, the design of the segment feeling mechanism is complex and occupies too much internal space of the mouse, so that the configuration flexibility of the internal components of the mouse is affected and the design of the mouse is not facilitated to be light and thin. Disclosure of utility model In view of the problems in the prior art, the present utility model provides a roller module, a mouse device and an input device, so as to solve the above problems. Accordingly, an object of the present utility model is to provide a roller module for an input device, the roller module comprising: A roller bracket; the roller is rotatably arranged on the roller bracket; A rotation sensor arranged on at least one side of the roller for detecting the rotation angle of the roller when the roller is forced to rotate, and The control circuit board is electrically connected with the rotation sensor and defines the corresponding relation between the rotation angle and the display picture controlled by the input device so as to control the input device to execute user-defined input operation. As an alternative solution, the rotation sensor includes: a magnet member disposed on the roller, and The at least one Hall effect sensor is arranged on the roller bracket, the at least one Hall effect sensor and the at least one magnet piece are opposite to each other, and the at least one Hall effect sensor is used for detecting the magnetic flux change of the magnet piece relative to the at least one Hall effect sensor along with the rotation of the roller when the roller is stressed to rotate so as to judge the rotation angle of the roller.
