Description

trackball structure

technical field

The invention relates to a trackball structure, which is applied to a mouse or a positioning device with a trackball to control the position of a cursor on a computer screen.

Background technique

Since Apple Computer introduced the mouse into the market in 1984, the mouse has become an indispensable input device when controlling a personal computer. Because of the shape of the mouse and the wires connected to it, it looks like a mouse and is called a mouse.

A general mouse is provided with a partially exposed trackball. When force is applied to roll the trackball, the two discs inside the mouse that are at right angles to each other will rotate with the trackball. At the same time, through optical detection, the The rotation speed of the two discs is converted into the moving distance on the Cartesian coordinates, so the cursor on the screen will relatively move from the initial position to the target position when the electronic instrument connected with the mouse is connected. However, such a mouse uses the wrist as the axis to apply force to move the mouse, so under long-term use, it is easy to cause soreness and damage to the wrist.

Of course, in order to satisfy various users' working patterns and habits of using computers, the design of the mouse is constantly innovating and improving. Therefore, the mouse developed so far has many items, and each has different functions and characteristics.

Such as the "improved structure of the third axis of the mouse" in the No. 364640 patent case of Taiwan, China, the "structural improvement of the optical trackball structure" in the No. 486121 patent case, and the "movable window in two directions simultaneously" in the No. 511749 patent case The technologies disclosed in the "mouse with scroll bar" and the "mouse in the palm" of the No. 547724 patent case, no matter whether these patent cases use an optical structure or a mechanical structure, mainly use the track that is generally arranged at the bottom of the mouse body The ball is set above the mouse body instead, so you can roll the trackball with your fingers, move the cursor, or even provide other functions, so it can effectively solve the situation that the desktop space is insufficient when the general mouse is moving, and it is not easy to bring desktop dust to the mouse. Inside, it is still necessary to continuously roll the trackball with the finger to move the cursor from the initial position to the target position. Although it is convenient to use, it is easy to cause soreness and damage to the base of the finger after long-term use.

Furthermore, although the technology of controlling the cursor with a joystick has been developed later, the cursor can be moved to the target position by pushing the joystick without continuously rolling the trackball, but after the joystick is pushed and released, its The restoring force of returning to the center position will put pressure on the fingers pushing the joystick. Once the joystick is farther from the center position, the pressure on the fingers will be greater, so long-term use will easily cause finger pain.

Contents of the invention

The main purpose of the present invention is to provide a trackball structure, which can be operated in a simplified manner with the least number of hands, conforms to ergonomics, and moves the cursor to a target position in a short time.

According to the trackball structure disclosed in the present invention, it is used to control the movement of the cursor. The trackball structure includes a main body, a storage groove, a trackball and a plurality of sensing components, wherein the storage groove is arranged on the main body, and the trackball part is exposed. is placed in the accommodation groove to control the movement of the cursor, and the sensing components are arranged around the trackball in the accommodation groove to sense the direction of pressure. When the trackball rolls and continuously touches in one direction When pressing on the sensing component, the cursor can continuously move in the aforementioned direction, and when the trackball is released, the cursor will stop moving, so it can be manipulated in a simplified way with the least amount of hand parts, and it is ergonomic, and in Move the cursor to the target position in a short time.

In order to further understand the purpose, structural features and functions of the present invention, the detailed description is as follows in conjunction with the accompanying drawings.

Detailed ways

According to the trackball structure disclosed in the present invention, it is applied to a mouse with a trackball or a positioning device (such as: a notebook computer, etc.), and the mouse or the positioning device is at least composed of a main body, a trackball, a cursor control assembly, It is composed of electrical signal induction device and electrical signal transmission device, etc. When the trackball is rolled, the electrical signal sensing device will generate a corresponding electrical signal, causing the electrical signal transmission device to transmit the electrical signal to the cursor control component and electronic equipment, and then control the position of the cursor through the cursor control component according to the electrical signal. The working principle of the ball mouse or the positioning device is a fairly mature technology, and will not be described in detail below.

Please refer to the three-dimensional combined view of the first embodiment of the present invention shown in FIG. 1 and the exploded view of the first embodiment of the present invention shown in FIG. It includes a body 10 , an accommodating slot 20 , a trackball 30 and a sensing component 40 .

The main body 10 is composed of an upper shell 11 and a base 12. The upper shell 11 is in a raised arc shape, which is convenient for the user to hold and manipulate, and fully conforms to the current ergonomic design concept.
