Mouse wheel and mouse wheel assembly thereof

Abstract

The invention discloses a mouse wheel and a mouse wheel assembly thereof. The mouse wheel assembly comprises the mouse wheel and a photocoupling pair transistor. The mouse wheel comprises a rolling-ball position-clamping mechanism, an outer wheel and a grate rolling shaft. The grate rolling shaft comprises a rolling shaft and multiple grates which are distributed by taking the rolling shaft as thecenter along the circumferential direction and are arranged on the rolling shaft. The grates are made of non-transparent material. The outer wheel is arranged on the outer surface of the grates in asleeving manner. Position-clamping grooves are uniformly distributed in the inner surface of the outer wheel. The rolling-ball position-clamping mechanism is provided with a movable rolling ball. Therolling ball matches the position-clamping grooves to movably clamp positions. The photocoupling pair transistor comprises an infrared pulse transmitting tube and an infrared impulse receiving tube, both of which are arranged on two sides of each grate. During rolling of the mouse wheel, emitting light clusters of the photocoupling pair transistor can be cut off in an alternating manner. A mouse can fulfill the functions of turning over pages, rolling and zooming. The service lifetime of the mouse is prolonged. The mouse wheel is high in function precision, more stable in working performance,more uniform and comfortable in rolling feel and great in rolling sense and can be suitable for different environments.

Description

technical field [0001] The invention belongs to the fields of mouse accessories, electronic products and computer peripheral equipment, and in particular relates to a mouse scroll wheel and a mouse scroll wheel assembly thereof. Background technique [0002] When people use a mouse to operate computers and other devices, functions such as scrolling up and down, page turning, and zooming of the operation content are required on the screen. At present, most mice on the market are realized by mechanical encoders. This method has the following disadvantages: [0003] 1. Due to the mechanical encoder, the service life is limited, generally 100,000-300,000 times. [0004] 2. During use, due to the mechanical type, it is easy to have poor contact, resulting in inaccurate page turning, scrolling, zooming, etc., and skipping phenomena (more or less page turning, too large or too small scrolling, too large or too small zooming) . [0005] 3. It is easy to be affected by the use envi...
