In some embodiments, the first magnetic member 21 may be a magnet, ferrite, or ferromagnetic member (e.g. a metal member such as iron, nickel, or cobalt), and the fixing module 20 may be fastened to the base 10 by fastening, adhering, or screwing.
For example, as shown in fig. 2 to 5, in the present embodiment, the fixing module 20 includes a first magnet 22, a fixing base 23 and a shaft 24, wherein the first magnet 22 is a permanent magnet (e.g. an alnico magnet or a ndfeb magnet) and has two different poles of N pole and S pole, the first magnetic member 21 is a metal gear plate (e.g. a metal plate such as iron, nickel or cobalt) and is attracted to one of the poles of the first magnet 22, so that the whole first magnetic member 21 can have the first pole, and the first magnetic member 21 and the first magnet 22 are assembled on the fixing base 23. Specifically, taking the perspective of fig. 5 as an example, assuming that the magnetic pole of the first magnet 22 near the left half of the fixed seat 23 is N pole, the magnetic pole of the first magnet 22 far from the right half of the fixed seat 23 is S pole, and the first magnetic member 21 is attracted to the surface of the first magnet 22 far from the right half of the fixed seat 23, so that the first magnetic member 21 is S pole.
As shown in fig. 2 to 5, in the present embodiment, the first magnetic member 21 has a first shaft hole 212, the first magnet 22 is a ring magnet and has a first central hole 221, one end of the shaft 24 is fixed on the fixing base 23, and the other end of the shaft 24 passes through the first shaft hole 212 and the first central hole 221. Here, the fixing base 23 further has a limiting post 233 at the center, one end of the shaft 24 is inserted into and fixed to the limiting post 233, the first central hole 221 of the first magnet 22 is sleeved around the limiting post 233 to obtain radial limitation, the first shaft hole 212 of the first magnetic member 21 is sleeved on the shaft 24 and is adsorbed to the first magnet 22 to obtain radial limitation, and the first magnetic member 21, the first magnet 22 and the fixing base 23 are coaxially arranged.
As shown in fig. 2 to 5, the roller module 30 is rotatably disposed on the base 10, in this embodiment, the roller module 30 is rotatably assembled to the shaft 24, so that the roller module 30 and the fixing module 20 are coaxially disposed, and the roller module 30 can rotate relative to the base 10 and the fixing module 20. The roller module 30 includes a second magnetic member 31 and a roller 35, wherein the roller 35 is connected to the second magnetic member 31 and can rotate synchronously with each other, and the housing 61 of the mouse 60 may be provided with a through hole 611 (as shown in fig. 2), and a partial area of the roller 35 penetrates through the through hole 611, so that a part of the roller 35 is exposed outside the housing 61 for a user to operate, for example, the roller 35 can be operated to roll to control the computer display to scroll up and down. In addition, the roller 35 may be sleeved with a ring 36 (e.g. a rubber ring or a silicone ring) to protect the roller 35 and improve the operation comfort.
As shown in fig. 2 to 5, the second magnetic member 31 of the roller module 30 and the first magnetic member 21 of the fixed module 20 are adjacent to each other and maintain a distance D1 (as shown in fig. 5, the distance D1 may be 0.5mm, 1mm, 2mm, etc.), which facilitates the rotation of the roller module 30 with respect to the fixed module 20. For example, as shown in fig. 5, in the embodiment, the roller 35 of the roller module 30 is further provided with at least one protruding column 351, and the protruding column 351 is propped against the fixed module 20, for example, the protruding column 351 can be propped against the fixed seat 23 or the first magnetic member 21, so that the second magnetic member 31 and the first magnetic member 21 can maintain a distance D1 and the fixed module 20 can obtain an axial limit through the dimension design of the protruding column 351. Alternatively, in another embodiment, as shown in fig. 8, which is an exploded perspective view of the second embodiment of the roller input device of the present invention, the distance D1 between the first magnetic member 21 and the second magnetic member 31 may also have a spacer 313, and the spacer 313 is integrally formed on the surface of the first body 211 of the first magnetic member 21 or the surface of the second body 311 of the second magnetic member 31, for example, in this embodiment, the spacer 313 is a plurality of protrusions integrally formed on the surface of the second body 311 of the second magnetic member 31, and the spacer 313 may contact the surface of the first body 211 of the first magnetic member 21, so that the distance D1 between the second magnetic member 31 and the first magnetic member 21 is maintained, and the fixing module 20 obtains an axial limit, and the roller 35 of the roller module 30 may not need to be provided with a protruding column 351.
As shown in fig. 2 to 5, the second magnetic member 31 of the roller module 30 includes a second body 311 and a plurality of second teeth 315, and the plurality of second teeth 315 are annularly arranged around the second body 311 to form the second magnetic member 31 in a gear shape, and keep the plurality of second teeth 315 at a distance without contacting each other. In the present embodiment, the second magnetic element 31 and the first magnetic element 21 are coaxially disposed, each second tooth portion 315 of the second magnetic element 31 has a second side face 316 facing each first tooth portion 215, the second side face 316 has a second magnetic pole, and the second magnetic pole and the first magnetic pole are mutually different-name poles and can attract each other, for example, when the first magnetic pole of the first side face 216 of the first magnetic element 21 is an N pole, the second magnetic pole of the second side face 316 of the second magnetic element 31 is an S pole.
In some embodiments, the second magnetic element 31 may be a magnet, ferrite, or ferromagnetic element (e.g., a metal element such as iron, nickel, or cobalt).
For example, as shown in fig. 2 to 5, in the embodiment, the roller module 30 further includes a second magnet 32, wherein the second magnet 32 is a permanent magnet (e.g. alnico magnet or ndfeb magnet) and has two different poles of N pole and S pole, the second magnetic member 31 is a metal gear plate (e.g. a metal plate such as iron, nickel or cobalt), the diameter of the second magnetic member 31 is the same as that of the first magnetic member 21, and the second magnetic member 31 is attracted to one of the poles of the second magnet 32, so that the whole second magnetic member 31 has the second magnetic pole. Specifically, taking the perspective of fig. 5 as an example, assuming that the magnetic pole of the second magnet 32 near the left half of the fixed seat 23 is N pole, the magnetic pole of the second magnet 32 far from the right half of the fixed seat 23 is S pole, and the second magnetic member 31 is attracted to the surface of the second magnet 32 near the left half of the fixed seat 23, so that the second magnetic pole of the second magnetic member 31 is N pole.
Referring to fig. 4 to 7, according to the above embodiment of the present invention, when the user operates the roller 35 to rotate relative to the fixed module 20, the second magnetic member 31 can rotate synchronously with the roller 35. In addition, during the rotation process of the second magnetic member 31, when the position of the first side surface 216 of each first tooth portion 215 of the first magnetic member 21 corresponds to the position of the second side surface 316 of each second tooth portion 315 of the second magnetic member 31 (as shown in fig. 6), the first magnetic pole of the first side surface 216 and the second magnetic pole of the second side surface 316 are different from each other, so that the first side surface 216 of each first tooth portion 215 and the second side surface 316 of each second tooth portion 315 have magnetic attraction force, and the user can feel the feel of a pause. In addition, when the positions of the first side surface 216 of each first tooth portion 215 of the first magnetic member 21 and the positions of the second side surface 316 of each second tooth portion 315 of the second magnetic member 31 are shifted from each other (as shown in fig. 7), there is no magnetic attraction between the first side surface 216 of each first tooth portion 215 and the second side surface 316 of each second tooth portion 315, so that the user can feel a paragraph touch through the change of the magnetic attraction between the first magnetic member 21 and the second magnetic member 31 during the rotation of the roller 35, and compared with the conventional mechanism, the embodiment of the invention has the advantages of avoiding mechanical errors, reducing running noise, reducing friction loss, and the like.
In addition, the user can control the rotation speed of the roller module 30 according to the actual use requirement to reduce the magnetic attraction force between the first magnetic member 21 and the second magnetic member 31, for example, when the rotation speed of the roller module 30 is higher, the magnetic attraction force when the first side surface 216 of the first magnetic member 21 and the second side surface 316 of the second magnetic member 31 correspond to each other is reduced, so as to reduce the resistance during operation to meet different use situations. In addition, when the rotational speed of the roller module 30 is greater than the threshold value, the magnetic attraction force between the first side surface 216 and the second side surface 316 becomes 0, so that the user does not generate resistance when operating the roller 35, and can perform rapid rotation or finer operation, so as to be suitable for some use cases (such as long-time or long-distance rolling of the roller 35, or finer rolling operation).
In some embodiments, the threshold is inversely proportional to the spacing D1 between the first magnetic member 21 and the second magnetic member 31. That is, the larger the distance D1 between the first magnetic element 21 and the second magnetic element 31, the smaller the threshold value.
In addition, as shown in fig. 4 and 5, the first magnetic element 21 and the second magnetic element 31 in the embodiment of the present invention generate magnetic poles by means of attracting magnets, so that the effects of reducing cost and manufacturing steps can be achieved without performing additional magnetizing operations on the first magnetic element 21 and the second magnetic element 31, and the magnetic force of the first magnetic element 21 and the second magnetic element 31 can be maintained and is not easy to be attenuated with time.
As shown in fig. 2 to 5, in the present embodiment, the base 10 is a semicircular hollow housing with a groove 102, and the base 10 is further provided with a slot 101 and a shaft hole 103, wherein the slot 101 and the shaft hole 103 are respectively located at two opposite sides of the groove 102. The roller 35 of the roller module 30 has a receiving groove 352 at one side, and the fixing module 20 and the roller module 30 are both accommodated in the receiving groove 352, so that the fixing module 20 and the roller module 30 can be assembled to form an assembly and then mounted in the groove 102 of the base 10 together, for example, in the embodiment, the fixing base 23 has a fastening portion 231, after the fixing module 20 and the roller module 30 are assembled, the fastening portion 231 of the fixing base 23 can be fastened and fixed in the fastening groove 101 of the base 10, and the end portion of the shaft 24 is inserted into the shaft hole 103 of the base 10, so that the fixing module 20 and the roller module 30 can be mounted in the groove 102 of the base 10 quickly.
As shown in fig. 5, in the present embodiment, the fastening portion 231 of the fixing base 23 further has a guiding inclined surface 232. Therefore, in the process of installing the fixing base 23 to the base 10, the user can apply force to press the fixing base 23 into the groove 102, and the buckling part 231 can be smoothly buckled in the buckling groove 101 through the guidance of the guiding inclined surface 232, so that the convenience of assembly is improved without using any auxiliary tool.
In some embodiments, at least one of the first body 211 of the first magnetic member 21 and the second body 311 of the second magnetic member 31 may be provided with a hollowed-out hole 312. For example, as shown in fig. 4, in the present embodiment, the second body 311 of the second magnetic member 31 is further provided with a hollowed hole 312 to reduce the magnetic attraction between the first body 211 of the first magnetic member 21 and the second body 311 of the second magnetic member 31, so as to reduce the resistance during operation and avoid affecting the operation feel.
As shown in fig. 4 and 5, the roller input device 1 further includes a roller sensing module 40, the roller sensing module 40 includes a magnet 41 and a Hall sensor 42 (Hall sensor), the magnet 41 is disposed on the roller 35, wherein the magnet 41 may be a permanent magnet (e.g. alnico magnet or ndfeb magnet) and has two different poles of N pole and S pole. In this embodiment, another accommodating groove 353 is provided on the other side of the roller 35 of the roller module 30 opposite to the accommodating groove 352, the magnet 41 is fixed in the accommodating groove 353 and can rotate synchronously with the roller 35, and the hall sensor 42 is disposed on the circuit board 70 and adjacent to the magnet 41. Therefore, when the magnet 41 rotates synchronously with the roller 35, the hall sensor 42 senses the magnetic field change to determine the distance, position or rotation speed of the roller 35.
Fig. 9 is an exploded perspective view of a third embodiment of the roller input device of the present invention, and fig. 10 is a cross-sectional view of the third embodiment of the roller input device of the present invention. As shown in fig. 9 and 10, the roller input device 2 of the present embodiment is different from the roller input device 1 of the first embodiment at least in that the first magnetic member 21a of the roller input device 2 of the present embodiment is a ferrite magnet, and the first magnetic member 21a can make each of the first teeth 215a arranged around the first body 211a have the first magnetic pole (for example, N pole) through the magnetizing operation. The second magnetic member 31a is also a ferrite magnet, each of the second teeth 315a arranged around the second body 311a may have the second magnetic pole (e.g., S pole) by magnetizing the second magnetic member 31a, the shaft 24 is directly fixed to the center of the first magnetic member 21a, the second magnetic member 31a is rotatably connected to the shaft 24, and the roller 35 is connected to the outer periphery of the second magnetic member 31a to be rotatable synchronously with the second magnetic member 31 a. Therefore, compared with the first embodiment, the present embodiment can omit the first magnet 22 and the second magnet 32, thereby reducing the assembly tolerance and improving the production efficiency.
As shown in fig. 9 and 10, the distance D1 is also maintained between the first magnetic element 21a and the second magnetic element 31a, when the user operates the roller 35 to rotate relative to the first magnetic element 21a, the second magnetic element 31a can rotate synchronously with the roller 35, and the user can feel the paragraph touch through the magnetic attraction change between the first magnetic element 21a and the second magnetic element 31a during the rotation of the roller 35, and the user can control the rotation speed of the roller 35 according to the actual use requirement to reduce the magnetic attraction between the first magnetic element 21a and the second magnetic element 31a, thereby reducing the resistance during the operation and meeting different use situations.
Fig. 11 is an exploded perspective view of a fourth embodiment of the wheel input device of the present invention, and fig. 12 is a cross-sectional view of the fourth embodiment of the wheel input device of the present invention. As shown in fig. 11 and 12, in the roller input device 3 of the present embodiment, compared with the roller input device 2 of the third embodiment, the first magnetic member 21b of the roller input device 3 of the present embodiment is also a ferrite magnet as is the second magnetic member 31b, the first magnetic member 21b can make each of the first teeth 215b arranged around the first body 211b have the first magnetic pole (for example, N pole) through the magnetizing operation, the second magnetic member 31b can make each of the second teeth 315b arranged around the second body 311b have the second magnetic pole (for example, S pole) through the magnetizing operation, the shaft 24 is directly fixed at the center of the first magnetic member 21b, the second magnetic member 31b is rotatably assembled on the shaft 24, and the roller 35 is connected to the outer periphery of the second magnetic member 31b so as to be capable of rotating synchronously with the second magnetic member 31 b.
As shown in fig. 11 and 12, the difference between the present embodiment and the third embodiment is that each first tooth portion 215b of the first magnetic member 21b of the present embodiment further has an outer side surface 217 away from the first body 211b, and the outer side surface 217 also has the first magnetic pole (for example, N pole) described above. The roller module 30b further includes a third magnetic member 33, the third magnetic member 33 includes an annular body 331 and a plurality of third teeth 335, the annular body 331 integrally extends from the second magnetic member 31b and surrounds the first magnetic member 21b, the annular body 331 has an inner circumference 332, the plurality of third teeth 335 are annularly arranged on the inner circumference 332 and maintain a distance D2 from the plurality of first teeth 215b, each third tooth 335 has a third magnetic pole, and the third magnetic pole and the first magnetic pole are mutually different from each other.
Therefore, as shown in fig. 11 and 12, when the user operates the roller 35 to rotate relative to the first magnetic member 21b, the second magnetic member 31b and the third magnetic member 33 can rotate synchronously with the roller 35, and during the rotation of the roller 35, the magnetic attraction between the first magnetic member 21b and the third magnetic member 33 can be changed in addition to the magnetic attraction between the first magnetic member 21b and the second magnetic member 31b, so that the feeling of the section touch is more obvious, and the user can control the rotation speed of the roller 35 according to the actual use requirement, so as to reduce the magnetic attraction between the first magnetic member 21b, the second magnetic member 31b and the third magnetic member 33, thereby reducing the resistance during the operation and meeting different use situations.
Although the present invention has been described with respect to the preferred embodiments, it should be understood by those skilled in the art that the present invention is not limited thereto, and that modifications and variations of the invention as herein defined may be made without departing from the spirit of the invention.
