Abstract
Description
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 a computer's display system. The input device is called a mouse because its outer shape resembles a mouse. The full name of a mouse is "mouse device", but it is usually abbreviated as a mouse. The purpose of using a mouse is to simplify computer operations and reduce complex operations performed by a 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 convenience 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 abuts against the wheel. However, the stepped operation feeling of the conventional mechanical encoder is too mechanical, has poor smoothness, and has the drawback of affecting the touch feeling.
Summary of the Invention
Problems to be Solved by the Invention
[0004] The objective of the present invention is to solve the problem of the stepped operation feel of mechanical encoders being too mechanical, resulting in poor smoothness and affecting tactile feel and durability, by providing a magnetically damped high-speed optical wheel to solve the problems of conventional technology. [Means for solving the problem]
[0005] To achieve the above objective, the present invention provides the following technical aspects. The magnetically attenuated high-speed optical wheel of the present invention includes a PCBA substrate, a central button mounted on the PCBA substrate, a left-side oscillating part, and a right-side oscillating part, a frame mounted on the surface of the PCBA substrate by a PCB substrate, and an optical sensor electrically connected to the PCBA substrate 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 circumferential surface of the magnetic inner shaft abuts against the magnetic outer shaft, and the outer circumferential 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 circumferential surface of the magnetic outer shaft, and a shaft sleeve is attached to 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 molded by injection molding, a coupling portion is integrally molded 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 portion is detachably coupled into the hole of the coupling hole.
[0007] Two positioning protrusions are formed symmetrically on the inner wall of the shaft sleeve, and two sets of positioning parts are formed symmetrically on the outer circumferential surface of the magnetic outer shaft. Each set of positioning parts includes two positioning plates, and the two positioning plates of each set of positioning parts are movably coupled to two positioning protrusions. A positioning rubber ring is attached between the magnetic outer shaft and the shaft sleeve, and a rubber ring is attached to the outer circumferential surface of the shaft sleeve.
[0008] The side walls of the surface of the positioning rubber ring abut against the surface of the magnetic outer shaft, and the outer side walls of the positioning rubber ring abut against the side walls on the back of the shaft sleeve. A recess is formed on the outer surface of the positioning rubber ring, and the side walls on the back of the recess slidably abut against the surface of the positioning projection.
[0009] A positioning groove is formed on the outer 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 connected to the inner wall of the positioning groove.
[0010] A left-side oscillating section and a right-side oscillating section are electrically connected to the upper part of the PCBA substrate, and a pressing section is integrally formed on the surface of the frame, with the pressing section being formed between the left-side oscillating section and the right-side oscillating section.
[0011] The optical sensor includes an optical receiver and an optical transmitter, both of which are mounted inside a frame, and optical passage holes are formed in a matrix pattern on the side surface of the magnetic outer shaft. [Effects of the Invention]
[0012] The following effects of the present invention can be achieved by the matters of the present invention. (1) The magnetically attenuated high-speed optical wheel of the present invention is fitted with a metal shaft, a magnetic inner shaft, a magnetic outer shaft, a first magnetic gear, and a second magnetic gear. 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 misaligned, the attractive force between the first magnetic gear and the second magnetic gear gradually weakens, and when the first magnetic gear and the second magnetic gear are positioned opposite each other, the attractive force between the first magnetic gear and the second magnetic gear gradually strengthens. By changing the attractive force between the first magnetic gear and the second magnetic gear, a stepped operating feel can be obtained when using the magnetically attenuated high-speed optical wheel of the present invention. Compared to the wheel of a mechanical encoder, the magnetically attenuated high-speed optical wheel of the present invention has the advantages of smooth operation, feel and durability, and can prevent wear of internal components.
[0013] (2) The magnetically attenuated high-speed optical wheel of the present invention is fitted with a shaft sleeve and a rubber ring. The attachment of the rubber ring increases the frictional force, allowing the shaft sleeve to rotate easily. When the shaft sleeve is rotated by an external force, the external force is greater than the attractive force between the first magnetic gear and the second magnetic gear, and the shaft sleeve can continue to rotate due to inertia. In the magnetically attenuated high-speed optical wheel of the present invention, the first magnetic gear and the second magnetic gear do not come into mechanical contact, so by rapidly rotating the shaft sleeve, it is possible to quickly navigate through and read web pages.
[0014] When implementing any of the products or methods of the present invention, it is not necessary for all of the effects of the invention to be achieved simultaneously. [Brief explanation of the drawing]

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. Those 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", "perimeter", 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 an embodiment of the present invention, the following technical matters are provided, that is, a magnetic damping type (Magnetic Damping) high-speed optical wheel (Optical Wheel). The magnetic damping type high-speed optical wheel includes a PCBA (Printed Circuit Board Assembly) substrate 1 and a middle button 2 attached on the PCBA substrate 1. A frame 4 is attached to 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 attached inside the frame 4.
[0019] [[ID=二十]] Inside the frame 4, a magnetic inner shaft 6 fixed by a metal shaft 5 is attached. On the surface of the magnetic inner shaft 6, first magnetic gears 7 are evenly formed. 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. On the inner peripheral surface of the magnetic outer shaft 8, second magnetic gears 9 corresponding to the first magnetic gears 7 are formed, 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 gears 7 on the magnetic inner shaft 6 project in the direction approaching the magnetic outer shaft 8, and the second magnetic gears 9 on the inner wall of the magnetic outer shaft 8 project in the direction approaching the magnetic inner shaft 6. Both the first magnetic gears 7 and the second magnetic gears 9 are arranged in a matrix shape, and the first magnetic gears 7 and the second magnetic gears 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 gears 7 and the second magnetic gears 9 are arranged to face each other, the adsorption force between the first magnetic gears 7 and the second magnetic gears 9 becomes the strongest. As the magnetic outer shaft 8 continues to rotate, when the positions of the first magnetic gears 7 and the second magnetic gears 9 are arranged to be displaced, the adsorption force between the first magnetic gears 7 and the second magnetic gears 9 gradually weakens. As the magnetic outer shaft 8 continues to rotate, when the first magnetic gears 7 and the second magnetic gears 9 are arranged to face each other again, the adsorption force between the first magnetic gears 7 and the second magnetic gears 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 gears 7 and the second magnetic gears 9 are not mechanically connected and are assembled integrally 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 molded by injection molding, a coupling portion 11 is integrally molded on one side of the magnetic inner shaft 6, a coupling hole 12 is formed on the surface of the frame 4, and 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 molded by injection molding, and the metal shaft 5 can be inserted into a circular recess in the inner wall of the frame 4. A bevel 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 undergoes elastic deformation due to the bevel of the coupling portion 11. Next, the coupling portion 11 of the magnetic inner shaft 6 is coupled into the hole of the coupling hole 12, thereby fixing the magnetic inner shaft 6 so that it cannot rotate.
[0023] Specifically, two positioning protrusions 13 are formed symmetrically (i.e., opposite each other) on the inner wall of the shaft sleeve 10, and two sets of positioning parts are formed symmetrically on the outer circumferential surface of the magnetic outer shaft 8. Each set of positioning parts includes two positioning plates 14, and the two positioning plates 14 of each set of positioning parts 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 circumferential 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 molded 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 shaft sleeve 10, the position of the gap between two adjacent positioning plates 14 corresponds to the position of the positioning projection 13. When inserting the magnetic outer shaft 8 into the shaft sleeve 10, the position of the magnetic outer shaft 8 is determined by the positioning projection 13 and the positioning plates 14. 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 magnetic outer shaft 8 can be prevented from falling.
[0025] Specifically, the back side wall 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 back side wall of the shaft sleeve 10. A recessed portion 17 is formed on the outer surface of the positioning rubber ring 15, and the back side wall of the recessed portion 17 slidably abuts against the surface of the positioning projection 13.
[0026] A positioning groove 18 is formed on the outer 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 connected to the inner wall of the positioning groove 18.
[0027] In this embodiment, a recessed portion 17 corresponding to a positioning projection 13 is formed on the positioning rubber ring 15. The positioning rubber ring 15 is made of rubber, and 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. This tightly connects the magnetic outer shaft 8 and the shaft sleeve 10, preventing 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 to the outside of the positioning rubber ring 15, the fixing portion 19 can be inserted into the positioning groove 18 of the shaft sleeve 10. This firmly connects the positioning rubber ring 15 to the shaft sleeve 10 and prevents the positioning rubber ring 15 from falling off.
[0028] Specifically, the left-side oscillating part 20 and the right-side oscillating part 21 are electrically connected to the upper part of the PCBA board 1, and a pressing part 22 is integrally formed on the surface of the frame 4, with the pressing part 22 being formed between the left-side oscillating part 20 and the right-side oscillating part 21.
[0029] In this embodiment, an annular groove is formed on the frame 4, and a support portion (not shown) corresponding to the annular groove is formed on the mouse shell. The shaft sleeve 10 rotates relative to the connection point between the support portion and the annular groove, thereby causing the frame 4 to oscillate, and the left oscillating portion 20 and the right oscillating portion 21 can be pressed by the push portion 22 integrally formed on the surface of the frame 4. By pressing the left oscillating portion 20 and the right oscillating portion 21 with the push portion 22, the frame 4 moves downward, and the central button 2 can be pressed with the frame 4 as it moves downward. This enables the realization of various functions, increases the functionality of the mouse, and allows the present invention to be used in various places.
[0030] Specifically, the optical sensor includes an optical receiver 23 and an optical transmitter 24, both of which are mounted inside the frame 4, and optical passage 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 from the optical transmitter 24. Specifically, the optical receiver 23 can receive the optical signal from the optical transmitter 24 only when the optical signal from the optical transmitter 24 passes through the optical passage hole 25 of the magnetic outer shaft 8. By intermittently receiving the optical signal from the optical transmitter 24, the optical receiver 23 can detect the rotation of the shaft sleeve 10, allowing the user to view web pages while navigating them.
[0032] When using a magnetically attenuated high-speed optical wheel, the user can rotate the shaft sleeve 10 by placing their finger against the rubber ring 16 of the shaft sleeve 10 and using the frictional force between their finger and the rubber ring 16. Since the metal shaft 5 and the magnetic inner shaft 6 are integrally molded 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 hole 25 on the magnetic outer shaft 8 rotates together with the magnetic outer shaft 8, and 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 from the optical transmitter 24 that has passed through the light-passing hole 25. Since both the first magnetic gear 7 and the second magnetic gear 9 contain 24 teeth, when the first magnetic gear 7 and the second magnetic gear 9 rotate one full turn, 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 rotates once, it is possible to browse a webpage while navigating it. In this embodiment, 12 optical passage holes 25 are formed in the magnetic outer shaft 8, and as the magnetic outer shaft 8 rotates, the optical passage holes 25 on the magnetic outer shaft 8 rotate together with the magnetic outer shaft 8, so that optical signals are intermittently transmitted between the optical receiver 23 and the optical transmitter 24 (i.e., the optical receiver 23 intermittently receives the optical signals from 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, it outputs a pulse of one half-wave period, and when the magnetic outer shaft 8 rotates once (360 degrees), it outputs 24 half-wave pulses. A list of output signals is shown in Figure 9. As shown in Figure 9, the rotational phase differences t1, t2, t3, and t4 are all greater than 10 ms.
[0033] Both the magnetic inner shaft 6 and the magnetic outer shaft 8 are magnetic. The first magnetic gear 7 on the magnetic inner shaft 6 protrudes toward the magnetic outer shaft 8, and the second magnetic gear 9 on the inner wall of the magnetic outer shaft 8 protrudes toward the magnetic inner shaft 6. Both the first magnetic gear 7 and the second magnetic gear 9 are arranged in a matrix, and in their natural state, one of each magnetic gear 7 and 9 corresponds to the other. When the magnetic outer shaft 8 rotates due to the drive of the shaft sleeve 10, the attractive force between the first magnetic gear 7 and the second magnetic gear 9 is strongest when they are positioned to face each other. As the magnetic outer shaft 8 continues to rotate, the attractive force between the first magnetic gear 7 and the second magnetic gear 9 gradually weakens as their positions shift. As the magnetic outer shaft 8 continues to rotate, the attractive force between the first magnetic gear 7 and the second magnetic gear 9 becomes strong again when they are positioned to face each other again. As a result, when using the magnetically attenuated high-speed optical wheel of the present invention, a stepped feel of operation can be obtained. Since both the first magnetic gear 7 and the second magnetic gear 9 contain 24 teeth, when the first magnetic gear 7 and the second magnetic gear 9 rotate once, they move 24 steps. One step of the first magnetic gear 7 or the second magnetic gear 9 corresponds to one stepped 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 once, the computer can detect the mouse wheel moving through a web page.
[0034] When the user rapidly rotates the shaft sleeve 10, if an external force cancels out the attractive 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 attractive force between the first magnetic gear 7 and the second magnetic gear 9 supports the shaft sleeve 10 continuing to rotate when the external force is removed. The rotating shaft sleeve 10 drives the magnetic outer shaft 8 to rotate, allowing for quick selection of functions and rapid browsing of web pages. Finally, due to the structural resistance and the attractive 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 positioned corresponding to each other.
[0035] An annular groove is formed on the frame 4, and a support part (not shown) corresponding to the annular groove is formed on the mouse shell. The shaft sleeve 10 rotates relative to the connection point between the support part and the annular groove, thereby causing the frame 4 to oscillate, and the push part 22 on the frame 4 can press the left oscillating part 20 and the right oscillating part 21. By pressing the left oscillating part 20 and the right oscillating part 21 with the push part 22, the frame 4 moves downward, and the central button 2 can be pressed with the frame 4 as it moves downward. This enables the realization of various functions, increases the functionality of the mouse, and allows the present invention to be used in various places.
[0036] As described above, by attaching the push part 22 and the shaft sleeve 10 to the magnetically attenuated high-speed optical wheel, the problems that arise when using conventional mechanical encoders—such as being too mechanical, having poor operational smoothness, and affecting the tactile feel—can be solved.
