Description

Technical Field

[0001] The utility model relates to a non-contact type electromagnetic roller of a mouse, belonging to the field of mice. Background Art

[0002] A mouse is a very common and frequently used computer input device, which can position the cursor on the current screen and operate the screen elements where the cursor passes through through buttons and scroll wheels; the standard name of "mouse" should be "mouse", and the use of mouse is to make computer operation easier, replacing the cumbersome keyboard commands.

[0003] The scroll wheel of a general mouse is of the contact type (encoder), which has the disadvantage that when the scroll wheel is rotated, there will be wear and tear, thereby reducing the service life of the scroll wheel and the mouse. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model provides a non-contact electromagnetic scroll wheel for a mouse. The technical solution of the utility model is:

[0005] A non-contact type electromagnetic scroll wheel for a mouse comprises a scroll wheel body, the scroll wheel body comprises a bottom plate and a scroll wheel bracket mounted on the bottom plate, a scroll wheel and a scroll wheel magnetic unit are rotatably mounted in a mounting groove of the scroll wheel bracket, a Hall chip bracket is mounted on the outer side of the scroll wheel bracket, a Hall element is mounted on the Hall chip bracket, and a scroll wheel magnetic unit corresponding to the Hall element is mounted on the side of the scroll wheel; when the scroll wheel rotates, the Hall element performs statistics on the scrolling data of the scroll wheel through induction with the scroll wheel magnetic unit, and outputs the corresponding signal to a computer through a micro control unit.

[0006] The roller magnetic unit is an electromagnet, which rotates the roller after being energized. When the roller rotates, the roller data is output through the induction between the electromagnet and the Hall element on the roller, and the rotation angle, speed and number of revolutions of the roller are calculated by the microcontroller unit and then transmitted to the computer.

[0007] The roller magnetic unit is a magnet, and there are several levels of magnets on the roller. The magnet is driven to rotate by the roller. When the roller is rotated, the output of the roller data is completed through the induction of the magnet and the Hall element on the roller, and the rotation angle, speed and number of circles of the roller are calculated by the micro control unit and then transmitted to the computer.

[0008] The Hall element is a Hall sensor.

[0009] The advantages of the utility model are:

[0010] (1) The previous method of coding switch (contact type) will cause wear and tear, resulting in damage to the roller or malfunction. The new structure is non-contact and has no wear problem, which greatly extends the service life of the roller and mouse.

[0011] (2) The damping coefficient of the roller is electronically controlled by applying pressure to the electromagnet.

[0012] (3) You can also add a mouse wheel shuttle mode (when viewing a multi-page document, you can quickly flip through the document pages). BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 4 The utility model relates to a non-contact electromagnetic scroll wheel for a mouse, comprising a scroll wheel body, the scroll wheel body comprising a bottom plate 1 and a scroll wheel bracket 2 mounted on the bottom plate 1, a scroll wheel 3 and a scroll wheel magnetic unit being rotatably mounted in a mounting groove of the scroll wheel bracket 2, a Hall chip bracket 4 being mounted on the outer side of the scroll wheel bracket 2, a Hall element 5 (the Hall element is a Hall sensor) being mounted on the Hall chip bracket 4, and a scroll wheel magnetic unit corresponding to the Hall element 5 being mounted on the side of the scroll wheel 3; when the scroll wheel 3 rotates, the Hall element 5 performs statistics on the scrolling data of the scroll wheel 3 through induction with the scroll wheel magnetic unit, and outputs the corresponding signal to a computer through a micro control unit.

[0019] like Figure 2As shown, the roller magnetic unit is an electromagnet. After the electromagnet is energized, the roller rotates. When the roller 3 is rotated, the electromagnet and the Hall element 5 on the roller 3 are inductively sensed to output the data of the roller 3, and the rotation angle, speed and number of revolutions of the roller are calculated by the microcontroller unit and then transmitted to the computer.

[0020] This embodiment replaces the original encoder and can realize the shuttle function of the mouse wheel by the inertia of the wheel and the magnetic force of the control electromagnet when the wheel rotates faster.

[0021] Fast rotation: When the inertia force of the roller is less than the magnetic force, the roller will stop and the electromagnet will attract it.

[0022] Slow rotation: When the inertial force is smaller than the magnetic force, increasing the magnetic force of the electromagnet will increase, the roller will stop, and the electromagnet will attract it.

[0023] Turn one grid: Utilize the characteristics of electromagnet NS to produce a grid-by-grid effect. Electromagnet can be used to control the problem of slow or fast rotation.

[0024] like Figure 3 As shown, the roller magnetic unit is a magnet, and there are several levels of magnets on the roller 3. The magnet is driven to rotate by the roller 3. When the roller 3 is rotated, the output of the roller data is completed through the induction of the magnet and the Hall element 5 on the roller 3, and the rotation angle, speed and number of revolutions of the roller are calculated by the micro control unit and then transmitted to the computer.

[0025] The working principle of this embodiment is: there are 24-level magnets on the scroll wheel 3. When it rotates, the NS magnetic force will create a sense of segmentation, which will have the same feel as the traditional encoder. Then, through the rotation of the magnet scroll wheel and chip detection, the angular speed and number of circles of the scroll wheel can be calculated and transmitted to the computer, replacing the original encoder. When the scroll wheel rotates faster, the inertia of the scroll wheel (magnetic force of the magnet) can be used to realize the shuttle function of the mouse scroll wheel.

[0026] Fast rotation: When the inertia force of the roller is less than the magnetic force, the roller will stop and be attracted by the magnet; Turn one grid: Use the characteristics of the magnet NS to produce a grid-by-grid effect.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
