Description

Technical Field

[0001] The invention relates to the technical field of cursor mobile device, in particular to a trackball cursor movement control device. Background Art

[0002] At present, the cursor movement of an external terminal device (such as a computer) is generally controlled by a mouse. Since the mouse is moved by the user, it is relatively arbitrary and difficult to achieve precise control. In particular, for usage scenarios where the cursor needs to be controlled to move in a straight line horizontally or vertically (such as drawing a straight line), it is difficult to achieve this using traditional mouse control methods. Summary of the invention

[0003] In order to overcome the defects in the prior art, the task of the present invention is to provide a trackball cursor movement control device which is more convenient for controlling the cursor to move linearly in the horizontal or vertical direction.

[0004] The task of the present invention is achieved through the following technical solutions:

[0005] A trackball cursor movement control device comprises a shell, a trackball, an X-axis, a Y-axis, an oblique axis, and a photoelectric sensing circuit board placed in the shell. The X-axis, the Y-axis, and the oblique axis are all horizontally arranged in the shell and can rotate freely around their own axes. The X-axis and the Y-axis are both provided with counterweights. The trackball is supported by the X-axis, the Y-axis, and the oblique axis. By rolling the trackball, at least one of the X-axis, the Y-axis, and the oblique axis can be driven to rotate. An opening is provided on the upper surface of the shell for exposing the top of the trackball to facilitate rolling the trackball. The diameter of the opening is smaller than the diameter of the trackball so as to prevent the trackball from falling off. The photoelectric sensing circuit board is fixedly arranged in the shell and a photoelectric sensing head thereon faces the trackball so that the photoelectric sensing head can sense the moving distance and direction of the trackball and generate a corresponding moving signal. The photoelectric sensing circuit board can transmit the moving signal to an external terminal device so as to control the movement of the cursor of the external terminal device.

[0006] As a preferred technical solution, the counterweight is a counterweight plate arranged at at least one end of the X-axis and the Y-axis, and / or the counterweight is at least one thickened shaft segment arranged on the X-axis and the Y-axis.

[0007] As a preferred technical solution, the angles between the oblique axis and the X-axis and the Y-axis are all 45°.

[0008] As a preferred technical solution, the X-axis, the Y-axis and the oblique axis are all arranged in the housing through bearings.

[0009] As a preferred technical solution, a light board is also provided in the shell, and a translucent material is provided on the shell to facilitate the light from the light board to pass through. The light board is mounted outside the trackball and fixedly connected to the shell, and the light board is electrically connected to the photoelectric sensing circuit board so that the light emitting state of the light board can be controlled according to the movement signal.

[0010] As a preferred technical solution, the shell includes a detachably connected upper cover, a lower cover and an annular decorative lamp cover, the outer edge of the decorative lamp cover is detachably connected to the middle hole of the upper cover, the inner circle of the decorative lamp cover is the opening, the upper surface of the lamp panel is provided with lamp beads and fixedly connected to the bottom of the decorative lamp cover, and the decorative lamp cover is made of a light-transmitting material.

[0011] Compared with the prior art, the trackball cursor movement control device of the present invention has the following advantages: ① When the trackball is rolled horizontally to control the cursor to move horizontally and linearly, the trackball will drive the Y axis perpendicular to the rolling direction to rotate; when the trackball is rolled vertically to control the cursor to move vertically and linearly, the trackball will drive the X axis perpendicular to the rolling direction to rotate. By arranging counterweights on the X axis and the Y axis, the rotational inertia of the X axis and the Y axis is larger than that of the oblique axis, so that it is easier to control the cursor to move horizontally or vertically by rolling the trackball; ② The trackball is supported by arranging three axes, namely, the X axis, the Y axis and the oblique axis, which are arranged in a triangle, and the angles between the oblique axis and the X axis and the Y axis are all 45°, so that the cursor can be controlled to move horizontally and linearly, vertically and obliquely at 45° by rolling the trackball, which is more convenient to control than controlling the cursor to move in other directions; ③ A light board is built in, and the light board can control the light-emitting state of the light board according to the movement signal, which can increase the use experience and visual effect of the product.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0020] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or indirectly connected through an intermediate component. The "photoelectric sensor circuit board" and "photoelectric sensor head" in this article are both relatively mature existing technologies, and their specific structures and working principles will not be described and limited in detail in this article.

[0021] like Figure 1-5 As shown, the trackball cursor movement control device of the present invention comprises a housing 1, a trackball 2, an X-axis 3, a Y-axis 4, an oblique axis 5, and a photoelectric sensing circuit board 6 placed in the housing 1. The X-axis 3, the Y-axis 4, and the oblique axis 5 are all horizontally arranged in the housing 1 through bearings 7 and can freely rotate around their own axes. Compared with the oblique axis 5, the X-axis 3 and the Y-axis 4 are both provided with a counterweight plate 8 at one end, and the middle of the X-axis 3 and the Y-axis 4 are both provided with a thickened shaft section. The X-axis 3, the Y-axis 4, and the oblique axis 5 are arranged in a triangle, and the angles between the oblique axis 5 and the X-axis 3 and the Y-axis 4 are all 45°. The trackball 2 is supported by the X-axis 3, the Y-axis 4, and the oblique axis 5. The X-axis 3, the Y-axis 4, and the oblique axis 5 can be driven by rolling the trackball 2. At least one of the inclined axes 5 rotates, and an opening 131 is provided on the upper surface of the housing 1 for exposing the top of the trackball 2 to facilitate rolling the trackball 2. The diameter of the opening 131 is smaller than the diameter of the trackball 2 to prevent the trackball 2 from falling off. The photoelectric sensing circuit board 6 is fixedly arranged in the housing 1 and is located directly below the trackball 2 through the pressing block 63. The photoelectric sensing head 61 on the photoelectric sensing circuit board 6 faces the trackball 2, so that the photoelectric sensing head 61 can sense the moving distance and direction of the trackball 2 and generate a corresponding moving signal. The data line interface 62 at the bottom of the photoelectric sensing circuit board 6 can transmit the moving signal to an external terminal device (such as a computer) to control the cursor movement of the external terminal device.

[0022] When in use, when the trackball 2 is rolled horizontally to control the cursor to move horizontally and linearly, the trackball 2 will drive the Y axis 4 perpendicular to the rolling direction to rotate. When the trackball 2 is rolled vertically to control the cursor to move vertically and linearly, the trackball 2 will drive the X axis 3 perpendicular to the rolling direction to rotate. By arranging a counterweight plate 8 on the X axis 3 and the Y axis 4 and arranging a thickened axis section on the X axis 3 and the Y axis 4, the rotational inertia of the X axis 3 and the Y axis 4 is larger than that of the oblique axis 5, so that when the cursor is controlled to move horizontally or vertically by rolling the trackball 2, the X axis 3 and the Y axis 4 are rotated horizontally or vertically. It becomes easier to control; by setting three axes, namely, the X-axis 3, the Y-axis 4 and the oblique axis 5, which are arranged in a triangle, to support the trackball 2, and the angles between the oblique axis 5 and the X-axis 3 and the Y-axis 4 are all 45 degrees, so that the cursor can be controlled to move horizontally, vertically and 45 degrees obliquely by rolling the trackball 2, which is more convenient to control than controlling the cursor to move in other directions. Controlling the cursor to move horizontally, vertically and 45 degrees obliquely is precisely the most important and commonly used usage scenario in certain fields.

[0023] As a preferred embodiment, the shell 1 includes a detachably connected upper cover 11, a lower cover 12 and an annular decorative lamp cover 13, the outer edge of the decorative lamp cover 13 is detachably connected to the middle hole of the upper cover 11 by a snap mechanism, the inner circle of the decorative lamp cover 13 is an opening 131, and a lamp board 9 is also provided in the shell 1. The lamp board 9 is a lamp board 9 with a marquee lighting effect, and lamp beads 91 are provided on the upper surface of the lamp board 9. The lamp board 9 is sleeved on the outside of the trackball 2 and fixedly connected to the decorative lamp cover 13. The decorative lamp cover 13 is made of a light-transmitting material. The lamp board 9 is electrically connected to the photoelectric sensing circuit board 6 through a lamp line 92 so that the lighting state of the lamp board 9 can be controlled according to the mobile signal. This design can increase the user experience and visual effect of the cursor movement control device of the trackball 2 of the present invention, and is easy to disassemble and maintain.
