Roller module for mouse device

The invention relates to a roller module, which is applied to a mouse device, in particular to a roller module which is convenient for a user to press a roller.

The mouse device and keyboard are common input devices in computer devices for moving the cursor position or typing on the screen.

The mouse device is usually equipped with a left button, a right button and a scroll wheel. When the user browses the contents of the file on the screen, such as a text file, a spreadsheet, a picture file or a web page, etc., it is sometimes necessary to adjust the boundary range or size displayed on the screen. In this case, the wheel on the mouse device can be used. To achieve the above objectives. The wheel module in the prior art generally includes a wheel and a detector for detecting the rotation state of the wheel. In general, the rollers are typically assembled within the housing of the mouse and partially exposed to the housing, such as disclosed in U.S. Patent No. 5,921,261. However, in the conventional mouse device, the micro switch is generally disposed on the side of the roller, and a large force is required to press the roller, and the roller must be tilted when pressed. Therefore, the mouse wheel is more laborious to use, and the tilted mouse wheel also causes the rotation of the mouse wheel to be scrolled and cannot be accurately controlled.

In view of this, the present inventors have felt that the above-mentioned deficiency can be improved, and it is a research and cooperation with the application of the theory, and finally proposes a present invention which is rational in design and effective in improving the above-mentioned deficiency.

The main object of the present invention is to provide a roller module applied to a mouse device, which can facilitate the user to apply force to press the roller.

In order to solve the above technical problem, the present invention provides a roller module mounted on a mouse device, the mouse device has a micro switch, and the roller module includes a fixed seat, a swing seat and a roller. The swing seat is attached to the fixed seat through the rotating shaft so as to be swingable up and down with respect to the fixed seat. The roller is mounted to the rocking seat in a manner of rotating relative to the rocking seat, and the bottom side of the rocking seat has a pressure plate. When the roller is pressed by the force, the swing seat is rotated by a predetermined angle with respect to the fixed seat, so that the pressure plate is pressed against the micro switch of the mouse device.

According to the roller module provided by the present invention, the rotation axis of the rotating shaft is defined as a first center, and the rotating axis of the roller is defined as a second center. The distance from the first center to the second center is defined as the swing radius. With the first center of the circle as the center and the radius of the swing as the radius, the swinging circumference is formed. The point at which the pressure plate and the micro switch contact each other is defined as a pressure contact, and the pressure contact is located on the swing circumference.

According to the roller module provided by the present invention, the center of rotation of the rotating shaft is defined as a first center, and the axis of rotation of the roller is defined as a second center. The distance from the first center to the second center is defined as a first force arm, and the point at which the pressure plate and the micro switch contact each other is defined as a pressure contact, and the distance from the first center to the pressure contact is defined as a second force arm, and the second force The arm is less than or equal to the first arm.

The beneficial technical effect of the present invention is that the user presses the force of the roller through the swing seat relative to the fixed seat, and can directly transmit to the pressure plate below the swing seat, thereby pressing against the micro switch, and the roller of the mouse can be easily pressed and used. It's easier and less laborious.

A first screw hole 1121 is defined in the first bottom plate 112, and a second screw hole 1221 is defined in the second bottom plate 122. The fixing base 10 can be locked to the mouse device 100 by using a fixing member (not shown) such as a screw to pass through the first screw hole 1121 of the first bottom plate 112 and the second screw hole 1221 of the second bottom plate 122. Figure 1) above. A window 212 is further defined on the first wall surface 21 for the optical reading module (not shown) to detect the rotation state of the roller 40. A recess 222 is further defined in the second wall surface 22, and the rotating shaft 41 of the roller 40 can straddle the recess 222. on.

The pressing plate 25 is formed on the inclined surface portion 24 on the bottom side of the rocking seat 20, and in the present embodiment, the inclined surface portion 24 is formed into a pressing plate 25 by press. The pressure plate 25 may be, but not limited to, a bump, a bump, a horizontal strip, or a plate member. In the present embodiment, the pressure plate 25 is a plate shape. The pressure plate 25 may be integrally formed with the rocking seat 20 or may be additionally added to the rocking seat 20, and the assembly of the pressure plate 25 and the rocking seat 20 is not limited in this embodiment.

Please refer to FIG. 6, FIG. 7, and FIG. In the present embodiment, for convenience of description, the rotation axis of the rotating shaft 30 is defined as the first center C1, the rotation axis of the roller 40 is the second center C2, and the distance from the first center C1 to the second center C2 is defined as the swing radius. R. A swinging circumference D is formed with the first center C1 as a center and a swing radius R as a radius. The point at which the pressure plate 25 contacts the microswitches 50 is defined as a press contact T1, and the press contact is located on the swing circumference R.

When the user presses the roller 40, the rocking seat 20 is rotated by a predetermined angle with respect to the fixed seat 10, and the pressure plate 25 located at the bottom side of the rocking seat 20 is pressed against the micro switch 50. In other words, the second center C2 and the pressing contact T1 move back and forth on the swing radius R, and the user presses the force of the roller 40 to directly press the micro switch 50, thereby achieving the purpose of labor saving.

The pressure contact T1 between the pressure plate 25 and the micro switch 50 is not necessarily at the swing radius R.
