Description

Technical Field

[0001] The invention relates to a mouse device, in particular to a mechanical mouse. Background Art

[0002] Mechanical mouse is also called turntable mouse. When dragging the mouse, it drives the ball to rotate, and the ball drives the roller to rotate. The photoelectric pulse signal generated by the grating signal sensor installed at the end of the roller reflects the displacement change of the mouse in the vertical and horizontal directions, and then controls the movement of the cursor arrow on the screen through the processing and conversion of the computer program. It does not have a sheet-shaped round wheel perpendicular to each other at the bottom, but uses a four-way rolling colloid ball instead. When the ball rolls, it will drive a pair of shafts to rotate (X shaft and Y shaft respectively). There is a circular decoding wheel at the end of the shaft, and the decoding wheel is attached with a metal conductive sheet that is in direct contact with the brush. When the shaft rotates, these metal conductive sheets will contact the brush in turn, and there will be two forms of "on" or "off", the former corresponds to the binary number "1", and the latter corresponds to the binary number "0". Next, these binary signals are sent to the dedicated chip inside the mouse for analysis and processing and generate corresponding coordinate change signals. As long as the mouse moves on a plane, the ball will drive the shaft to rotate, thereby changing the on-off state of the decoding wheel, generating a set of different coordinate offsets, which will be reflected on the screen, that is, the cursor can move with the movement of the mouse.

[0003] This type of mechanical mouse uses a rotating shaft to directly drive the grating disk when changing the light signal, and the rotation speed of the grating disk determines the transmission speed of the light signal, the sensitivity of the mouse and the positioning accuracy. Due to the size of the mouse, the rotation speed of the grating disk of the existing mechanical mouse is not high enough to meet the accuracy of some games or large-screen use.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-6 As shown, the specific embodiment of the present invention is a mechanical mouse, including a rolling ball 10, a horizontal and vertical roller shaft 20 (the two roller shafts are vertically arranged, and are mutually horizontal and vertical roller shafts in the drawings) a bottom plate 3 and a circuit board 31 installed on the bottom plate, wherein the horizontal and vertical roller shafts 20 are fixed on the bottom plate 30 through an axis frame 21, and the rolling ball 10 is arranged between the horizontal and vertical roller shafts 20, and a rotating disk 22 is respectively arranged at one end of the horizontal and vertical roller shafts 20, and each rotating disk 22 corresponds to a transmission shaft assembly 23, and the transmission shaft assembly 23 includes a bracket 231, a bracket installed on the bracket The transmission shaft 232 on the rotating disk 22 and the small roller 233 installed on the transmission shaft, the small roller 233 is in close contact with the corresponding rotating disk 22, the rotating disk 22 drives the small roller 233 to rotate by friction, and the small roller 233 drives the transmission shaft 232 to rotate; the end of the transmission shaft 232 is also fixedly installed with a grating disk 40, the grating disk 40 is installed with a light pair tube 41 composed of a light emitting element and a photosensitive element, and the light pair tube 41 is mounted on the circuit board 31, and the rolling of the ball 10 is converted into the rotation of the grating disk 40, so that the light pair tube 41 outputs a signal. When the rolling ball 10 is rotated, according to the rotation direction, the rolling ball 10 drives the horizontal and vertical rollers 20 to rotate together, and the rollers 20 on both sides respectively rotate the grating disk 40 through the rotating disk 22 and the small roller 233, and the light signal between the light pair tube 41 is converted into an electrical signal; driven by the rotating disk 22 and the small roller 233, the grating disk 4 rotates faster, and the mouse is more accurate and sensitive to use.

[0022] The grating disk 40 is provided with a grating ring composed of a number of evenly distributed light holes 42, and the center of the grating ring is the rotation center point of the grating disk 40; in order to reduce light interference, the bracket 231 close to one end of the grating disk 40 is an opaque panel with a light slit 234, and the width of the light slit 234 matches the size of the light hole 42. The light emitted by the light-emitting element passes through the light slit and then to the light hole 42 and is then received by the photosensitive element. Since the output response frequency depends on the photosensitive element, adding the light slit makes the light transmission more uniform and has strong anti-interference performance, further increasing the sensitivity of the mouse.

[0023] The mouse also has a function of adjusting the sensitivity level. Specifically, the small roller 233 is mounted on the transmission shaft 232 so as to slide left and right. The small roller 233 is provided with an adjustment seat 50. The radial position of the small roller 233 in the rotating disk 22 can be adjusted by moving the adjustment seat 50 to adjust the transmission ratio. Figure 1 As shown in the figure, when the adjustment seat is close to the center of the turntable, the small roller rotates slowly and the sensitivity level is low. Figure 2 As shown, when the position adjustment seat moves to the periphery of the turntable, the small roller drives the grating disk to rotate faster, and the sensitivity level is higher. During operation, an adjustment block 51 extending from the bottom plate 30 is provided at the bottom of the position adjustment seat 50. The adjustment block 51 is set in a groove 52 opened in the bottom plate. By moving the position of the adjustment block in the groove of the bottom plate, the relative position of the position adjustment seat and the center of the roller circle is controlled. The speed ratio of the horizontal rolling axis and the vertical rolling axis can also be adjusted separately, which is more suitable for existing wide-screen computers.

[0024] In order to adjust the sensitivity of the mouse within the maximum range, the length of the transmission shaft 232 is greater than or equal to the radius of the turntable 22. When the small roller is close to the center of the turntable, the rotation speed is slow. When the small roller moves to the periphery of the turntable, the rotation speed increases.

[0025] In order to prevent the small roller from slipping, the cross section of the transmission shaft 232 is a square structure, and the through hole in the small roller 233 is a matching square shape, which increases the adhesion of the small roller on the transmission shaft.

[0026] The working principle of the mouse is as follows: when the roller ball is rotated, the roller ball drives the horizontal and vertical rollers to rotate along the direction of rotation. The turntable at one end of the horizontal and vertical rollers is driven by a transmission shaft assembly, and the transmission shaft assembly drives the grating disk to rotate. The rolling of the roller ball is converted into the rotation of the grating disk, thereby causing the light-pairing tube to output a signal; the mouse has multi-level sensitivity, and can control the position of the small roller wheel by moving the adjustment block in the groove of the bottom plate. When the small roller wheel is in the center area of ​​the turntable, the driving speed is slower, and when the small roller wheel is in the outer circle area of ​​the turntable, the driving speed is faster. By changing the driving speed of the small roller on the turntable in this way, the effect of changing the transmission ratio of the grating disk is achieved, and finally different sensitivities and precisions of the mouse are achieved. The speed ratio of the horizontal and vertical roller axes can also be adjusted separately, which is more suitable for use with existing wide-screen computers.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any slight modification, equivalent substitution and improvement made to the above embodiment based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
