The invention provides a mouse encoder.
Referring to fig. 1 to 4, in an embodiment of the present invention, the mouse encoder includes a circuit board 10, a mounting base 30, and an encoder disc 50. The circuit board 10 is provided with an optical transmitter 11, a first optical receiver 13 and a second optical receiver 15, the first optical receiver 13 is communicated with the optical transmitter 11 to form a first optical path, and the second optical receiver 15 is communicated with the optical transmitter 11 to form a second optical path; the mounting seat 30 is arranged on the circuit board 10; the coding disc 50 is rotatably arranged on the mounting base 30 and can be lifted relative to the mounting base 30; when the encoding disc 50 rotates relative to the mounting seat 30, the first light path and the second light path can be blocked in sequence along the rotation direction of the encoding disc 50; when the code wheel 50 is lifted relative to the installation, the first light path and the second light path can be blocked simultaneously.
In an embodiment of the present invention, the circuit board 10 may be configured to mount the optical transmitter 11, the first optical receiver 13, and the second optical receiver 15, and may detect a change in an optical signal of a first optical path formed between the optical transmitter 11 and the first optical receiver 13 and a change in an optical signal of a second optical path formed between the optical transmitter 11 and the second optical receiver 15. The optical transmitter 11, the first optical receiver 13, and the second optical receiver 15 may be fixed to the circuit board 10 by soldering, so as to achieve mechanical connection and electrical connection at the same time. Of course, the present application is not limited thereto, and in other embodiments, the optical transmitter 11, the first optical receiver 13, and the second optical receiver 15 may be adhered to the circuit board 10 by glue. And the first optical receiver 13 and the second optical receiver 15 may be in a separate arrangement, i.e. two receiving dies are packaged separately. Of course, the first optical receiver 13 and the second optical receiver 15 may be integrally disposed, that is, two receiving dies are integrally packaged. The mounting block 30 may be used to mount the code wheel 50 so that the code wheel 50 can be rotated and raised and lowered well. The code wheel 50 may be used to connect with a mouse wheel of a mouse to block a first optical path formed between the optical transmitter 11 and the first optical receiver 13 and/or a second optical path formed between the optical transmitter 11 and the second optical receiver 15 when the mouse wheel is driven. That is, when the code wheel 50 is driven by the mouse wheel to rotate forward, the first light path formed between the light emitter 11 and the first light receiver 13 can be blocked first; when the code wheel 50 is driven by the mouse wheel to rotate backwards, a second light path formed between the light emitter 11 and the second light receiver 15 can be blocked first; when the code wheel 50 is driven by the mouse wheel to descend, the code wheel can simultaneously block a first optical path formed between the optical transmitter 11 and the first optical receiver 13 and a second optical path formed between the optical transmitter 11 and the second optical receiver 15, so that the circuit board 10 respectively and correspondingly identifies the corresponding operation of the mouse wheel according to the optical signal changes of the first optical path and the second optical path: forward scrolling, backward scrolling, and pressing operations.
When the mouse encoder of the technical scheme of the invention is applied to a mouse, when a mouse roller of the mouse rolls forwards, the mouse roller can drive the encoding disc 50 of the mouse encoder to rotate forwards relative to the mounting seat 30. At this time, the code wheel 50 may block a first optical path formed between the optical transmitter 11 and the first optical receiver 13, and then the circuit board 10 may detect that an optical signal of the first optical path changes first, so as to recognize the operation of the mouse wheel scrolling forward, so that the mouse completes the corresponding instruction input according to the operation of the mouse wheel scrolling forward. When the mouse wheel of the mouse rolls backward, the mouse wheel can drive the code disc 50 of the mouse encoder to rotate backward relative to the mounting seat 30. At this time, the code wheel 50 may block a first optical path formed between the optical transmitter 11 and the second optical receiver 15, and then the circuit board 10 may detect that an optical signal of the second optical path changes first, so as to recognize a backward scrolling operation of the mouse wheel, so that the mouse completes a corresponding instruction input operation according to the backward scrolling operation of the mouse wheel.
In addition, since the code disc 50 of the mouse encoder of the present disclosure can also be lifted relative to the mounting base 30, when the mouse wheel is pressed, the mouse wheel can drive the code disc 50 to descend relative to the mounting base 30. At this time, the code wheel 50 can block the first optical path and the second optical path at the same time, and then the circuit board 10 can detect the optical signal changes occurring at the same time of the first optical path and the second optical path, so as to recognize the operation that the mouse wheel is pressed, so that the mouse can complete the corresponding instruction input according to the pressing operation of the mouse wheel. Therefore, the mouse encoder in the scheme can not only recognize the front and back rotation of the mouse wheel, but also recognize the pressing determination of the mouse wheel. Therefore, the using function of the mouse encoder is diversified, and the practicability of the mouse encoder is improved.
Referring to fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, a receiving groove 31 is formed in a surface of the mounting base 30 facing the circuit board 10, the receiving groove 31 is covered on an outer side of the optical transmitter 11, the first optical receiver 13 and the second optical receiver 15, and the code wheel 50 is rotatably disposed in the receiving groove 31.
It can be understood that, through the cover of the mounting seat 30 for the optical transmitter 11, the first optical receiver 13, the second optical receiver 15 and the code disc 50, the optical transmitter 11, the first optical receiver 13, the second optical receiver 15 and the code disc 50 can be installed more hermetically, and the influence of external dust on the optical transmitter 11, the first optical receiver 13, the second optical receiver 15 and the code disc 50 is reduced, so that the work precision and the service life of the optical transmitter 11, the first optical receiver 13, the second optical receiver 15 and the code disc 50 are ensured. Meanwhile, due to the arrangement, the space occupation can be reduced due to the fact that the installation among the mouse encoders is compact, and the overall size of the mouse encoder is favorably reduced. The mounting seat 30 may have a substantially arch shape, so that the upper end of the mounting seat 30 has a circular arc shape to be more adapted to the shape of the code wheel 50. In order to improve the convenience of repairing and replacing the light emitter 11, the first light receiver 13, the second light receiver 15 and the code wheel 50 located in the receiving groove 31, the mounting seat 30 may be detachably connected to the circuit board 10. For example, the outer wall surface of the mounting seat 30 may be connected with a connecting plate 351, the connecting plate 351 is provided with a mounting hole, a screw passes through the mounting hole and is inserted into the circuit board 10, so that the mounting seat 30 and the circuit board 10 can be stably connected, and meanwhile, the mounting process is simple. Of course, the present application is not limited thereto, and in other embodiments, the mounting base 30 may be connected to the circuit board 10 by a snap. In order to improve the convenience of processing and molding the receiving groove 31, the mounting seat 30 may include a housing 35 of the face cover 33, and the face cover 33 and the housing 35 are disposed opposite to each other in the axial direction of the encoding disk 50 and enclose the receiving groove 31 and the notch of the receiving groove 31. The face cover 33 and the housing 35 may be connected by screws, or may be fixed by snap connection or magnetic attraction, so as to improve the convenience of assembling the two. At this time, the connection plate 351 may be provided on the housing 35, and opposite ends of the rotation shaft of the code wheel 50 may pass through the face cover 33 and the housing 35, respectively, so as to be connected to the mouse wheel.
Referring to fig. 3, fig. 4, fig. 5 and fig. 6, in an embodiment of the present invention, the code wheel 50 is formed with a plurality of first reflective surfaces 51, and the plurality of first reflective surfaces 51 are distributed at intervals along a circumferential direction of the code wheel 50; the groove side wall of the accommodating groove 31 is formed with a second reflecting surface 311, and the second reflecting surface 311 is located above the first light receiver 13 and the second light receiver 15; the optical signal emitted from the optical transmitter 11 is formed into a first optical path to the first optical receiver 13 via the first reflection surface 51 and the second reflection surface 311, and the optical signal emitted from the optical transmitter 11 is formed into a second optical path to the second optical receiver 15 via the first reflection surface 51 and the second reflection surface 311.
It is understood that the optical path between the optical transmitter 11 and the first and second optical receivers 13 and 15 is conducted through the first and second reflection surfaces 51 and 311, and the first reflection surface 51 is disposed on the code wheel 50. The position of the first reflection surface 51 can be changed by the rotation of the code wheel 50 without additionally providing a light blocking member for blocking the light path between the light emitter 11 and the first and second light receivers 13 and 15, so that the light path between the first reflection surface 51 and the second reflection surface 311 is changed. Therefore, the structure of the mouse encoder is simplified, and the manufacturing cost of the mouse encoder is reduced. Of course, the present application is not limited thereto, and in other embodiments, the encoding disk 50 is not formed with the first reflecting surfaces 51, and the encoding disk 50 is additionally connected with the light blocking members, and the light blocking members may sequentially pass directly between the light emitter 11 and the first and second light receivers 13 and 15 during the rotation of the encoding disk 50. That is, when the encoding disk 50 is rotated, the optical path between the light emitter 11 and the first and second light receivers 13 and 15 is blocked by the plurality of flag members.
Referring to fig. 3 and 4, in an embodiment of the invention, a plurality of light-reflecting grooves 53 are formed on a lateral peripheral surface of the code wheel 50, the light-reflecting grooves 53 are distributed at intervals along a circumferential direction of the code wheel 50, and a groove bottom wall of the light-reflecting groove 53 is formed as the first reflecting surface 51.
It can be understood that the first reflective surface 51 is formed by forming the reflective groove 53, so that the groove is formed on the side circumferential surface of the encoding disk 50 without an additional structure, thereby improving the convenience of processing and forming the first reflective surface 51. Meanwhile, because the first reflecting surface 51 is located in the reflecting groove 53, the groove side wall of the reflecting groove 53 can reflect and gather light to a certain extent, so that the light is enhanced, and the first light receiver 13 and the second light receiver 15 can stably and effectively receive light signals. The first reflecting surface 51 can be an inclined surface, so that the first reflecting surface 51 is relatively flat and the convenience of processing and molding is further improved. Of course, the present application is not limited thereto, and in other embodiments, the first reflective surface 51 may also be a circular arc surface to perform better convergence enhancement on the light.

It is understood that the first light shielding cover 313 can provide a good isolation between the optical transmitter 11 and the first and second optical receivers 13 and 15, so that the optical signal emitted from the optical transmitter 11 can only pass through the first reflective surface 51, the first light-transmitting hole 3133 and the second reflective surface 311 to the first and second optical receivers 13 and 15 in sequence. Therefore, the position of the first reflection surface 51 is changed when the first encoder rotates, the first optical path between the light emitter 11 and the first light receiver 13 or the second optical path between the light emitter 11 and the second light receiver 15 can be stably and effectively changed, and the circuit board 10 is further ensured to effectively identify the rolling operation of the mouse wheel. Meanwhile, the cavity wall of the first light-gathering cavity 3131 may also reflect and gather some light rays, so as to enhance the intensity of the light rays and further facilitate the stable and effective reception of the light signals by the first light receiver 13 and the second light receiver 15. The first light-shielding cover 313 may be integrated with the mounting base 30 to improve the sealing performance of the first light-collecting cavity 3131 and the stability of the connection of the first light-shielding cover 313. Of course, the present application is not limited thereto, and in other embodiments, the first light shielding cover 313 may be fixed to the mounting base 30 by gluing. The second reflecting surface 311 may be an inclined surface, so that the second reflecting surface 311 is relatively flat and the convenience of processing and forming is improved. Of course, the present application is not limited thereto, and in other embodiments, the second reflective surface 311 may also be a circular arc surface to perform better convergence enhancement on the light.
Referring to fig. 5, in an embodiment of the present invention, the code wheel 50 is provided with a plurality of first through holes 55, the plurality of first through holes 55 all penetrate through two opposite sidewall surfaces of the code wheel 50 in the axial direction and are distributed at intervals along the circumferential direction of the code wheel 50, and one of the two opposite sidewall surfaces of the code wheel 50 is formed as the first reflection surface 51 in a region between every two adjacent first through holes 55.
It will be appreciated that the first reflecting surface 51 is formed by forming the first reflecting surface 51 in the area between each adjacent two of the first through holes 55 of the code wheel 50, so that the first reflecting surface 51 is indirectly formed by opening the first through holes 55 through the code wheel 50. In this case, the first through hole 55 is easily processed, thereby facilitating the formation of the first reflecting surface 51. The first through hole 55 may be a rectangular hole or a square hole, so that the shape of the first through hole 55 is regular, and the complexity of processing the first through hole 55 is further simplified. In addition, the present invention is not limited to this, and in another embodiment, a reflective film may be attached to a side wall surface of the code wheel 50 in the axial direction thereof, and the reflective film may be formed as the first reflective surface 51. In this case, the material of the code wheel 50 may be opaque. In an embodiment of the present invention, when one of the two opposite side wall surfaces of the code wheel 50 is formed as the first reflection surface 51 in the area between each two adjacent first through holes 55, the groove side wall of the accommodating groove 31 is provided with the second light shield 314, the second light shield 314 and the groove side wall of the accommodating groove 31 surround to form the second light condensation cavity 3141, and the second light shield 314 is provided with the second light transmission hole 3143 at the position corresponding to the first reflection surface 51; the first light receiver 13 and the second light receiver 15 are both located in the second light-condensing cavity 3141, and the groove sidewall of the accommodating groove 31 is formed with a second reflection surface 311 at a position corresponding to the second light-transmitting hole 3143.
It can be understood that the second light shield 314 can provide a good isolation between the optical transmitter 11 and the first optical receiver 13 and the second optical receiver 15, so that the optical signal emitted from the optical transmitter 11 can only be transmitted to the first optical receiver 13 and the second optical receiver 15 through the first reflection surface 51, the second light-transmitting hole 3143 and the second reflection surface 311 in sequence. Therefore, the position of the first reflection surface 51 is changed when the first encoder rotates, the first optical path between the light emitter 11 and the first light receiver 13 or the second optical path between the light emitter 11 and the second light receiver 15 can be stably and effectively changed, and the circuit board 10 is further ensured to effectively identify the rolling operation of the mouse wheel. Meanwhile, the cavity wall of the second light-focusing cavity 3141 may also perform a reflective focusing function on some light rays, so as to enhance the intensity of the light rays and further facilitate the stable and effective reception of the light signals by the first light receiver 13 and the second light receiver 15. The second light shielding cover 314 may be an integral structure with the mounting base 30, so as to improve the sealing performance of the second light condensing cavity 3141 and the stability of the connection of the second light shielding cover 314. Of course, the present application is not limited thereto, and in other embodiments, the second light shielding cover 314 is fixed to the mounting base 30 by gluing.
Referring to fig. 5 and 6, in an embodiment of the invention, a light-gathering groove 3145 is further disposed on a surface of the second light-shielding cover 314 where the second light-transmitting hole 3143 is formed, and the light emitter 11 is located in the light-gathering groove 3145.
It can be appreciated that by disposing the light emission in the light-gathering groove 3145, the groove sidewall of the light-gathering groove 3145 can provide a certain light emission and gathering effect to reduce the loss of power of the light during the transmission process. Further, a groove top wall of the light collection groove 3145 above the light emitter 11 may be formed as the third reflection surface 3147. At this time, the optical signal emitted from the optical transmitter 11 sequentially passes through the third emitting surface, the first reflecting surface 51, and the second reflecting surface 311 to form a first optical path to the first optical receiver 13, and the optical signal emitted from the optical transmitter 11 sequentially passes through the third reflecting surface 3147, the first reflecting surface 51, and the second reflecting surface 311 to form a second optical path to the second optical receiver 15. By providing the third reflecting surface 3147, the light emitting direction of the light emitter 11 can be set in a vertical direction, that is, the light emitter 11 can be mounted on the circuit board 10 upright, thereby improving the convenience of mounting. The third reflective surface 3147 can be an inclined surface, and the third reflective surface 3147 is smooth, so that the convenience of processing and molding is improved. Of course, the third reflective surface 3147 may also be a circular arc surface to enhance the light convergence. In addition, the present invention is not limited to this, and in other embodiments, the third reflection surface 3147 is not formed, the optical transmitter 11 is installed in an inclined manner, and the emitted optical signal may be directly transmitted to the first reflection surface 51.
Referring to fig. 7, in an embodiment of the present invention, the accommodating groove 31 is formed with a first reflecting wall 315 and a second reflecting wall 316 on two opposite groove side walls in the axial direction of the encoding disk 50; the periphery of the code wheel 50 is provided with a plurality of second through holes 57, the plurality of second through holes 57 penetrate through two opposite side wall surfaces of the code wheel 50 in the axial direction and are distributed at intervals along the circumferential direction of the code wheel 50, one second through hole 57 is located between the first reflection wall 315 and the second reflection wall 316, an optical signal emitted by the optical transmitter 11 passes through the first reflection wall 315 and the second reflection wall 316 to form a first optical path to the first optical receiver 13, and an optical signal emitted by the optical transmitter 11 passes through the first reflection wall 315 and the second reflection wall 316 to form a second optical path to the second optical receiver 15.
It is understood that the first reflective wall 315 and the second reflective wall 316 are formed on two opposite side walls of the accommodating groove 31, so that the code wheel 50 can be disposed relatively in the middle of the accommodating groove 31, and the light emitter 11 and the first light receiver 13 and the second light receiver 15 can be disposed on two opposite sides of the code wheel 50. The overall structure of the mouse encoder is relatively regular, so that the stability of the overall structure is improved. The first reflective wall 315 and the second reflective wall 316 may be both inclined surfaces, so that the first reflective wall 315 and the second reflective wall 316 are relatively flat and easy to machine. Of course, the present application is not limited thereto, and in other embodiments, the first reflective wall 315 and the second reflective wall 316 may also be curved surfaces.
Referring to fig. 7 and 8 in combination, in an embodiment of the invention, a third light shielding cover 317 is disposed on a side wall of the accommodating groove 31, the third light shielding cover 317 and the side wall of the accommodating groove 31 surround to form a third light-transmitting cavity 3171, and a third light-transmitting hole 3173 is disposed at a position of the third light shielding cover 317 corresponding to the first reflective wall 315; the first light receiver 13 and the second light receiver 15 are both located in the third light-transmitting cavity 3171, and a second reflective wall 316 is formed on a groove sidewall of the accommodating groove 31 at a position corresponding to the third light-transmitting hole 3173.
It is understood that the third light shield 317 can provide a good isolation between the optical transmitter 11 and the first optical receiver 13 and the second optical receiver 15, so that the optical signal emitted by the optical transmitter 11 can only pass through the first reflective wall 315, the second through hole 57, the third light-transmitting hole 3173 and the second reflective wall 316 to the first optical receiver 13 and the second optical receiver 15. Therefore, the position of the third light hole 3173 is changed when the first encoder rotates, the light path between the first reflection wall 315 and the second reflection wall 316 can be blocked, and then the first light path between the light emitter 11 and the first light receiver 13 or the second light path between the light emitter 11 and the second light receiver 15 can be stably and effectively changed, so that the circuit board 10 can effectively identify the rolling operation of the mouse wheel.
Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the mouse encoder further includes an elastic member 70, and the elastic member 70 is disposed on the mounting base 30 and elastically abuts against a lower surface of the code wheel 50.
It can be understood that the code wheel 50 can be driven by the mouse wheel to descend, so that the elastic member 70 is compressed to generate an elastic force. When the elastic element 70 is reset, the code disc 50 can be driven to ascend, so that the code disc 50 can be reset effectively and quickly with a few sounds.
Referring to fig. 2 and fig. 3 in combination, in an embodiment of the present invention, the elastic member 70 is a torsion spring, the torsion spring has a first torsion arm 71 abutting against the lower surface of the code wheel 50, and the first torsion arm 71 is formed with a protruding section 711 facing the code wheel 50; the side circumference of the code wheel 50 is provided with a plurality of limiting grooves 59, the limiting grooves 59 are distributed at intervals along the circumference of the code wheel 50, and the protruding section 711 of the first torsion arm 71 is embedded in one limiting groove 59.
It can be understood that, by abutting the protruding section 711 of the first torsion arm 71 with the limiting groove 59 (in the process that the encoder is driven by the mouse wheel to rotate, the protruding sections 711 of the first torsion arm 71 are embedded into the limiting groove 59 one by one), a certain resistance can be provided to generate a hand feeling when the encoding disc 50 is driven by the mouse wheel to rotate, so that the user can control the rotation speed of the mouse wheel conveniently. Namely, the effect that the mouse wheel rolls too fast to influence the instruction input (for example, the mouse wheel turns pages too fast and moves too fast) is reduced. The elastic member 70 is a torsion spring, so that one elastic member 70 can limit the code wheel 50 and can also limit the damping during the rotation process, thereby reducing the manufacturing cost. Wherein, the torsion spring may further include a second torsion arm 73, and the second torsion arm 73 may be connected to the mounting seat 30 to improve the stability of the torsion spring mounting. Further, the installation block 37 is disposed in the accommodation groove 31 of the installation seat 30, the installation block 37 may be provided with an installation groove 371, and the main body portion 75 of the torsion spring (the first torsion arm 71 and the second torsion arm 73 are connected to both ends of the main body portion 75) may be accommodated in the installation groove 371, so as to further limit and fix the torsion spring through the groove wall of the installation groove 371. At this time, the first torsion arm 71 of the torsion spring may extend below the code wheel 50 through the groove sidewall of the mounting groove 371, and the second torsion arm 73 of the torsion spring is inserted into the groove bottom wall of the mounting groove 371. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the elastic member 70 may also be an elastic sheet.
Referring to fig. 2 and 3, in an embodiment of the present invention, the mounting base 30 is provided with a guide block 39, and when the encoder descends relative to the mounting base 30, the first torsion arm 71 of the elastic element 70 is guided by the guide block 39 and collides with the mounting base 30 when elastically returning.
It can be understood that when the encoding disc 50 is driven to descend by the mouse wheel, the elastic member 70 can be driven by the guiding block 39, and then the elastic member 70 can collide with the mounting seat 30 to generate a prompt sound when elastically returning, so as to prompt the user to press a certain operation. Therefore, the possibility of missing or repeated pressing of the pressing operation of the mouse wheel can be reduced, and the convenience of the mouse in use is improved. Wherein the upper end of the guide block 39 may form a first guide surface to guide the elastic member 70 to rotate when the encoder descends with respect to the mounting seat 30. Further, the lower end of the guide block 39 may be formed with a second guide surface so that the second guide surface may rotate to return to the initial position by bypassing the guide block 39 during the returning and raising of the first torsion arm 71 of the elastic member 70. The first guide surface and the second guide surface may both be inclined surfaces, with the first guide surface being inclined downwardly and the second guide surface being inclined upwardly.
