Magnetic Attenuation Type High-Speed Optical Wheel

Abstract

The present invention belongs to the technical field of mice, and specifically relates to a magnetic damping type high-speed optical wheel. 【Solution means】The magnetic damping type high-speed optical wheel of the present invention includes a PCBA board, a central button, a left swing part, and a right swing part mounted on the PCBA board. A frame is mounted on the surface of the PCBA board by a PCB board, and an optical sensor electrically connected to the PCBA board is mounted inside the frame. A plurality of light passing holes are evenly formed on the outer periphery of the magnetic outer shaft, and the plurality of light passing holes are formed at intervals on both sides of the IR / PT. When the first position of the magnetic outer shaft is in the on state, it is turned off when the magnetic outer shaft rotates one step. When the first position is in the off state, it is turned on when the magnetic outer shaft rotates one step, and the magnetic outer shaft can enter the next cycle by continuing to rotate. A pressing part and a shaft sleeve are attached to the magnetic damping type high-speed optical wheel. When the magnetic outer shaft on which the first and second magnetic gears are evenly formed rotates by the drive of the shaft sleeve, when the first and second magnetic gears face each other, the adsorption force between the two magnetic gears becomes the strongest. When the positions of the first magnetic gear and the second magnetic gear are displaced, the adsorption force between the two magnetic gears gradually weakens. Since both the first and second magnetic gears include 24 teeth, when the first or second magnetic gear rotates one full circle, it moves 24 steps, and one step corresponds to one step-by-step operation feeling.

Technical Field

[0001] The present invention belongs to the technical field of mice, and specifically relates to a magnetic damping type high-speed optical wheel.

Background Art

[0002] A mouse is an external input device used for a computer and is an indicator that determines the vertical and horizontal coordinate positions of the computer's display system. The input device is called a mouse because its outer shape resembles a mouse. The full name of the mouse is "mouse device", but it is usually abbreviated as mouse. The purpose of using a mouse is to simplify computer operations and reduce complex operations performed by the keyboard. An infrared light source is attached to a mouse that uses an optical wheel. Such a mouse has very high responsiveness and a refresh frequency, and has the advantages of good flexibility and accuracy during operation.

[0003] In the prior art, the wheel of a mechanical encoder obtains a stepped operation feeling due to the structure of the encoder itself. Specifically, a plastic face gear is attached inside the encoder, and the raster wheel obtains a stepped operation feeling when the iron wire on the wheel contacts the wheel. However, the stepped operation feeling of the conventional mechanical encoder is too mechanical, lacks smoothness, and has the drawback of affecting the touch feeling.

Means for Solving the Problems

[0005] To achieve the above object, the present invention provides the following technical matters. The magnetic damping type high-speed optical wheel of the present invention includes a PCBA substrate, a central button, a left swing part, and a right swing part mounted on the PCBA substrate. A frame is mounted on the surface of the PCBA substrate by a PCB substrate, and an optical sensor electrically connected to the PCBA substrate is mounted inside the frame. A magnetic inner shaft fixed by a metal shaft is mounted inside the frame, and a first magnetic gear is evenly formed on the surface of the magnetic inner shaft. The outer peripheral surface of the magnetic inner shaft abuts against a magnetic outer shaft, and the outer peripheral surface of the metal shaft is movably coupled to the inner wall of the magnetic inner shaft. A second magnetic gear corresponding to the first magnetic gear is formed on the inner peripheral surface of the magnetic outer shaft, and a shaft sleeve is mounted on the surface of the magnetic outer shaft.

[0006] One end of the metal shaft is inserted into the inner wall of the frame, the metal shaft and the magnetic inner shaft are integrally formed by injection molding, a coupling part is integrally formed on one side of the magnetic inner shaft, a coupling hole is formed on the surface of the frame, and the surface of the coupling part is detachably coupled to the inside of the coupling hole.

[0007] Two positioning protrusions are symmetrically formed on the inner wall of the shaft sleeve, and two sets of positioning parts are symmetrically formed on the outer peripheral surface of the magnetic outer shaft. One set of positioning parts includes two positioning plates, and the two positioning plates of each set of positioning parts are movably coupled to the two positioning protrusions. A positioning rubber ring is mounted between the magnetic outer shaft and the shaft sleeve, and a rubber ring is mounted on the outer peripheral surface of the shaft sleeve.

[0008] The side wall on the surface of the positioning rubber ring abuts against the surface of the magnetic outer shaft, and the outer side wall of the positioning rubber ring abuts against the back side wall of the shaft sleeve. A recess is formed on the surface of the outer peripheral surface of the positioning rubber ring, and the side wall on the back side of the recess slidably abuts against the surface of the positioning protrusion.

[0009] A positioning groove is formed on the surface of the outer peripheral surface of the shaft sleeve, and a fixing portion is integrally formed on the surface of the positioning rubber ring. The surface of the fixing portion is detachably coupled to the inner wall of the positioning groove.

[0010] A left swing portion and a right swing portion are electrically connected to the upper part of the PCBA board, and a pressing portion is integrally formed on the surface of the frame. The pressing portion is formed between the left swing portion and the right swing portion.

[0011] The optical sensor includes a photoreceiver and an optical transmitter. Both the photoreceiver and the optical transmitter are mounted inside the frame, and light passing holes are formed in a matrix on the side surface of the magnetic outer shaft.

Advantages of the Invention

[0012] According to the present invention, the following advantages of the invention can be achieved. (1) In the magnetic damping type high-speed optical wheel of the present invention, a metal shaft, a magnetic inner shaft, a magnetic outer shaft, a first magnetic gear and a second magnetic gear are mounted. When the magnetic outer shaft rotates due to the drive of the shaft sleeve, if the positions of the first magnetic gear and the second magnetic gear are displaced, the adsorption force between the first magnetic gear and the second magnetic gear gradually weakens. When the first magnetic gear and the second magnetic gear are made to face each other, the adsorption force between the first magnetic gear and the second magnetic gear gradually becomes stronger. By changing the adsorption force between the first magnetic gear and the second magnetic gear, when using the magnetic damping type high-speed optical wheel of the present invention, a stepped operation feeling can be obtained. Compared with the wheel of a mechanical encoder, the magnetic damping type high-speed optical wheel of the present invention has the advantages of good smoothness, touch feeling and durability, and can prevent wear of internal parts.

[0013] (2) A shaft sleeve and a rubber ring are attached to the magnetic damping type high-speed optical wheel of the present invention. By attaching the rubber ring, the frictional force can be increased, and the shaft sleeve can be easily rotated. When the shaft sleeve is rotated by an external force, the external force is greater than the adsorption force between the first magnetic gear and the second magnetic gear, and the shaft sleeve can continue to rotate due to inertia. In the magnetic damping type high-speed optical wheel of the present invention, since the first magnetic gear and the second magnetic gear do not mechanically contact each other, by quickly rotating the shaft sleeve, it is possible to read while quickly moving the web page.

[0014] When implementing any product or method of the present invention, it is not necessary to necessarily exhibit all the effects of the above-mentioned inventions simultaneously.

Embodiments for Carrying out the Invention

[0016] Hereinafter, the technical matters of the present invention will be described in more detail with reference to the drawings according to the embodiments of the present invention. It should be noted that the following embodiments are merely illustrative of the present invention and do not represent all embodiments of the present invention. A person skilled in the art can imagine other embodiments based on the following embodiments without creative research, and it is natural that such embodiments are included in the scope of the claims of the present invention.

[0017] In the specification of the present invention, it should be noted that the directions or positions defined by terms such as "opening", "upper", "lower", "heat", "upper part", "middle part", "length", "back side", "periphery", etc. represent the directions or positions on the drawing, and do not explicitly or implicitly indicate that the modules or components of the present invention have specific directions, positions, structures or operations. That is, there is no intention to limit the present invention by such terms.

[0018] Referring to FIGS. 1 to 10, in the embodiment of the present invention, the following technical matters are provided, that is, a magnetic damping type high-speed optical wheel. The magnetic damping type high-speed optical wheel includes a PCBA (Printed Circuit Board Assembly) substrate 1 and a middle button 2 mounted on the PCBA substrate 1. A frame 4 is mounted on the surface of the PCBA substrate 1 by a PCB (Printed Circuit Board) substrate 3, and an optical sensor electrically connected to the PCBA substrate 1 is mounted inside the frame 4.

[0019] Inside the frame 4, a magnetic inner shaft 6 fixed by a metal shaft 5 is attached, and a first magnetic gear 7 is evenly formed on the surface of the magnetic inner shaft 6. The outer peripheral surface of the magnetic inner shaft 6 abuts against a magnetic outer shaft 8, and the outer peripheral surface of the metal shaft 5 is movably coupled to the inner wall of the magnetic inner shaft 6. A second magnetic gear 9 corresponding to the first magnetic gear 7 is formed on the inner peripheral surface of the magnetic outer shaft 8, and a shaft sleeve 10 is attached to the surface of the magnetic outer shaft 8.

[0020] Both the magnetic inner shaft 6 and the magnetic outer shaft 8 have magnetic fields. The first magnetic gear 7 on the magnetic inner shaft 6 protrudes in a direction approaching the magnetic outer shaft 8, and the second magnetic gear 9 on the inner wall of the magnetic outer shaft 8 protrudes in a direction approaching the magnetic inner shaft 6. Both the first magnetic gear 7 and the second magnetic gear 9 are arranged in a matrix shape, and the first magnetic gear 7 and the second magnetic gear 9 in the natural state are arranged to correspond one by one. When the magnetic outer shaft 8 rotates by the drive of the shaft sleeve 10, when the first magnetic gear 7 and the second magnetic gear 9 are arranged to face each other, the adsorption force between the first magnetic gear 7 and the second magnetic gear 9 becomes the strongest. As the magnetic outer shaft 8 continues to rotate and the positions of the first magnetic gear 7 and the second magnetic gear 9 are arranged to be displaced, the adsorption force between the first magnetic gear 7 and the second magnetic gear 9 gradually weakens. As the magnetic outer shaft 8 continues to rotate and the first magnetic gear 7 and the second magnetic gear 9 are arranged to face each other again, the adsorption force between the first magnetic gear 7 and the second magnetic gear 9 becomes strong again. Thereby, when using the magnetic damping type high-speed optical wheel of the present invention, a stepped operation feeling can be obtained. The first magnetic gear 7 and the second magnetic gear 9 are not mechanically connected and are assembled together by the adsorption force of a plurality of magnetic gears. Thereby, a stepped operation feeling can be obtained, and the problem that the smoothness of a mechanical encoder is not good and it is too mechanical can be solved.

[0021] Specifically, one end of the metal shaft 5 is inserted into the inner wall of the frame 4. The metal shaft 5 and the magnetic inner shaft 6 are integrally formed by injection molding. A coupling portion 11 is integrally formed on one side of the magnetic inner shaft 6. A coupling hole 12 is formed on the surface of the frame 4. The surface of the coupling portion 11 is detachably coupled into the hole of the coupling hole 12.

[0022] In this embodiment, the metal shaft 5 and the magnetic inner shaft 6 are integrally formed by injection molding, and the metal shaft 5 can be inserted into the circular recess of the inner wall of the frame 4. An inclined surface is formed on the coupling portion 11 of the magnetic inner shaft 6. When the magnetic inner shaft 6 is assembled to the frame 4, the coupling portion 11 on the magnetic inner shaft 6 abuts against the surface of the frame 4, and the frame 4 is elastically deformed by the inclined surface of the coupling portion 11. Next, by coupling the coupling portion 11 of the magnetic inner shaft 6 into the hole of the coupling hole 12, the magnetic inner shaft 6 can be fixed so as not to rotate.

[0023] Specifically, two positioning protrusions 13 are formed symmetrically (i.e., facing each other) on the inner wall of the shaft sleeve 10, and two sets of positioning portions are formed symmetrically on the outer peripheral surface of the magnetic outer shaft 8. One set of positioning portions includes two positioning plates 14, and the two positioning plates 14 of each set of positioning portions are movably coupled to the two positioning protrusions 13. A positioning rubber ring 15 is attached between the magnetic outer shaft 8 and the shaft sleeve 10, and a rubber ring 16 is attached to the outer peripheral surface of the shaft sleeve 10.

[0024] In this embodiment, the shaft sleeve 10 is mounted on the magnetic outer shaft 8, the metal shaft 5 and the magnetic inner shaft 6 are integrally formed by injection molding, and the metal shaft 5 and the magnetic outer shaft 8 are movably coupled. That is, the metal shaft 5 can rotate relative to the magnetic outer shaft 8. By inserting the magnetic outer shaft 8 into the inside of the shaft sleeve 10, the position of the gap between two adjacent positioning plates 14 and the position of the positioning protrusion 13 are made to correspond. When the magnetic outer shaft 8 is inserted into the inside of the shaft sleeve 10, the positioning protrusion 13 and the positioning plate 14 determine the position of the magnetic outer shaft 8. By attaching the positioning rubber ring 15 between the magnetic outer shaft 8 and the shaft sleeve 10, the position of the magnetic outer shaft 8 can be determined and the fall of the magnetic outer shaft 8 can be prevented.

[0025] Specifically, the inner side wall of the back side of the positioning rubber ring 15 abuts against the surface of the magnetic outer shaft 8, and the outer side wall of the positioning rubber ring 15 abuts against the inner side wall of the back side of the shaft sleeve 10. A recessed portion 17 is formed on the surface of the outer peripheral surface of the positioning rubber ring 15, and the inner side wall of the back side of the recessed portion 17 slidably abuts against the surface of the positioning protrusion 13.

[0026] A positioning groove 18 is formed on the surface of the outer peripheral surface of the shaft sleeve 10, and a fixing portion 19 is integrally formed on the surface of the positioning rubber ring 15. The surface of the fixing portion 19 is detachably coupled to the inner wall of the positioning groove 18.

[0027] In this embodiment, a recessed portion 17 corresponding to the positioning protrusion 13 is formed on the positioning rubber ring 15. The material of the positioning rubber ring 15 is rubber. By assembling the positioning rubber ring 15 between the magnetic outer shaft 8 and the shaft sleeve 10, the frictional force between the magnetic outer shaft 8 and the shaft sleeve 10 can be increased. Thereby, the magnetic outer shaft 8 and the shaft sleeve 10 can be tightly coupled to prevent the magnetic outer shaft 8 or the shaft sleeve 10 from sliding relative to each other. A fixing portion 19 is integrally formed on the positioning rubber ring 15. Since the fixing portion 19 is formed to protrude outside the positioning rubber ring 15, the fixing portion 19 can be inserted into the positioning groove 18 of the shaft sleeve 10. Thereby, the positioning rubber ring 15 can be firmly coupled to the shaft sleeve 10 to prevent the positioning rubber ring 15 from falling off.

[0028] Specifically, a left swing portion 20 and a right swing portion 21 are electrically connected to the upper portion of the PCBA board 1, and a pressing portion 22 is integrally formed on the surface of the frame 4. The pressing portion 22 is formed between the left swing portion 20 and the right swing portion 21.

[0029] In this embodiment, an annular groove is formed on the frame 4, and a supporting portion (not shown) corresponding to the annular groove is formed on the shell of the mouse. By rotating the shaft sleeve 10 relative to the connection portion between the supporting portion and the annular groove, the swing of the frame 4 can be realized, and the left swing portion 20 and the right swing portion 21 can be pressed by the pressing portion 22 integrally formed on the surface of the frame 4. By pressing the left swing portion 20 and the right swing portion 21 with the pressing portion 22, the frame 4 moves downward, and the central button 2 can be pressed by the frame 4 moving downward. Thereby, various functions can be realized, the functions of the mouse can be increased, and the present invention can be used in various places.

[0030] Specifically, the optical sensor includes an optical receiver 23 and an optical transmitter 24. Both the optical receiver 23 and the optical transmitter 24 are mounted inside the frame 4, and optical through-holes 25 are formed in a matrix on the side surface of the magnetic outer shaft 8.

[0031] In this embodiment, the optical transmitter 24 transmits an optical signal, and the optical receiver 23 can receive the optical signal of the optical transmitter 24. Specifically, the optical receiver 23 can receive the optical signal of the optical transmitter 24 only when the optical signal of the optical transmitter 24 passes through the optical through-hole 25 of the magnetic outer shaft 8. By intermittently receiving the optical signal of the optical transmitter 24, the optical receiver 23 can detect the rotation of the shaft sleeve 10 and read while moving the web page.

[0032] When using a magnetic attenuation type high-speed optical wheel, the user can rotate the shaft sleeve 10 by bringing a finger into contact with the rubber ring 16 of the shaft sleeve 10 and relying on the frictional force between the finger and the rubber ring 16. Since the metal shaft 5 and the magnetic inner shaft 6 are integrally formed by injection molding, the shaft sleeve 10 can be driven so that the magnetic outer shaft 8 rotates together with the shaft sleeve 10. The light passing holes 25 on the magnetic outer shaft 8 rotate together with the magnetic outer shaft 8. The optical transmitter 24 of the optical sensor transmits an optical signal, and the optical receiver 23 can detect the rotation of the shaft sleeve 10 by receiving the optical signal of the optical transmitter 24 that has passed through the light passing holes 25. Since both the first magnetic gear 7 and the second magnetic gear 9 include 24 teeth, when the first magnetic gear 7 and the second magnetic gear 9 make one full rotation, the first magnetic gear 7 and the second magnetic gear 9 move 24 steps. One step of the first magnetic gear 7 or the second magnetic gear 9 corresponds to one stepwise operation, and one optical signal is output when the first magnetic gear 7 or the second magnetic gear 9 rotates one step. Therefore, by transmitting 24 signals when the first magnetic gear 7 or the second magnetic gear 9 makes one full rotation, it is possible to read while moving the web page. 12 light passing holes 25 are formed in the magnetic outer shaft 8 of this embodiment. When the magnetic outer shaft 8 rotates, the light passing holes 25 on the magnetic outer shaft 8 rotate together with the magnetic outer shaft 8, so that the optical signal is intermittently transmitted between the optical receiver 23 and the optical transmitter 24 (that is, the optical receiver 23 intermittently receives the optical signal of the optical transmitter 24), and a pulse voltage can be output. When the magnetic outer shaft 8 rotates by an amount corresponding to one tooth, a pulse of one half wave period is output, and when the magnetic outer shaft 8 makes one full rotation (360 degrees), 24 half wave pulses are output. The list of output signals is as shown in FIG. 9. As shown in FIG. 9, the rotational phase differences t1, t2, t3, t4 are all greater than 10 ms.

[0033] Both the magnetic inner shaft 6 and the magnetic outer shaft 8 have magnetism. The first magnetic gear 7 on the magnetic inner shaft 6 protrudes in the direction approaching the magnetic outer shaft 8, and the second magnetic gear 9 on the inner wall of the magnetic outer shaft 8 protrudes in the direction approaching the magnetic inner shaft 6. Both the first magnetic gear 7 and the second magnetic gear 9 are arranged in a matrix, and the first magnetic gear 7 and the second magnetic gear 9 in the natural state are arranged in a one-to-one correspondence. When the magnetic outer shaft 8 rotates driven by the shaft sleeve 10, when the first magnetic gear 7 and the second magnetic gear 9 are arranged to face each other, the adsorption force between the first magnetic gear 7 and the second magnetic gear 9 is the strongest. As the magnetic outer shaft 8 continues to rotate, when the positions of the first magnetic gear 7 and the second magnetic gear 9 are arranged to be displaced, the adsorption force between the first magnetic gear 7 and the second magnetic gear 9 gradually weakens. As the magnetic outer shaft 8 continues to rotate, when the first magnetic gear 7 and the second magnetic gear 9 are arranged to face each other again, the adsorption force between the first magnetic gear 7 and the second magnetic gear 9 becomes strong again. Thereby, when using the magnetic damping type high-speed optical wheel of the present invention, a step-by-step operation feeling can be obtained. Both the first magnetic gear 7 and the second magnetic gear 9 include 24 teeth. When the first magnetic gear 7 and the second magnetic gear 9 rotate one full circle, the first magnetic gear 7 and the second magnetic gear 9 move 24 steps. One step of the first magnetic gear 7 or the second magnetic gear 9 corresponds to one step-by-step operation, and one optical signal is output when the first magnetic gear 7 or the second magnetic gear 9 rotates one step. Therefore, by transmitting 24 signals when the first magnetic gear 7 or the second magnetic gear 9 rotates one full circle, the computer can detect the operation of the mouse wheel moving the web page.

[0034] When the user quickly rotates the shaft sleeve 10, if the external force cancels out the adsorption force between the first magnetic gear 7 and the second magnetic gear 9, the shaft sleeve 10 can continue to rotate due to inertia. The adsorption force between the first magnetic gear 7 and the second magnetic gear 9 supports the continuous rotation of the shaft sleeve 10 when the external force is removed. The rotating shaft sleeve 10 drives the magnetic outer shaft 8 to rotate, so that functions can be quickly selected and web pages can be read quickly. Finally, due to the resistance of the structure and the adsorption force between the first magnetic gear 7 and the second magnetic gear 9, the rotation of the magnetic outer shaft 8 stops, and the first magnetic gear 7 and the second magnetic gear 9 are arranged corresponding to each other one by one.

[0035] An annular groove is formed on the frame 4, and a supporting part (not shown) corresponding to the annular groove is formed on the shell of the mouse. When the shaft sleeve 10 rotates relative to the connection position between the supporting part and the annular groove, the rocking of the frame 4 can be realized, and the left rocking part 20 and the right rocking part 21 can be pushed by the pushing part 22 on the frame 4. By pushing the left rocking part 20 and the right rocking part 21 with the pushing part 22, the frame 4 moves downward, and the central button 2 can be pressed by the downward moving frame 4. Thereby, various functions can be realized, the functions of the mouse can be increased, and the present invention can be used in various places.

[0036] As described above, by attaching the pushing part 22 and the shaft sleeve 10 to the magnetic damping type high-speed optical wheel, when using a conventional mechanical encoder, the problems of being too mechanical, poor smoothness in use, and affecting the touch feel can be solved.

[0037] It should be noted that in this specification, although the matters with the first, second, etc. can distinguish any structure or operation from other objects or operations, there is no intention to limit the relationship or order between the structures or operations of the present invention by such matters.
