Description

Technical Field

[0001] The utility model relates to a roller of a mouse, in particular to a mouse and a magnetic roller module thereof. Background Art

[0002] The mouse includes a shell and a roller assembly and an encoder configured in the shell. The user can control the page scroll displayed on the screen to scroll up and down or left and right by turning the roller in the roller assembly to make the rolling roller interact with the encoder.

[0003] In order to allow the user to feel the scale when turning the scroll wheel, a magnetic scale-sensing structure is currently added to the mouse. However, the existing magnetic scale-sensing structure has an object between the magnet and the magnetically attracted part, such as a rubber ring mounted on the scroll wheel. In other words, the magnetically attracted part is indirectly attracted by the magnet, resulting in a weakened effect of the magnetic attraction of the magnetically attracted part by the magnet, thereby affecting the scale feel of the user when turning the scroll wheel.

[0004] Furthermore, since the existing roller assembly is already equipped with the above-mentioned magnetic scale sensing structure, there is no remaining space for adding other functional components, such as light-guiding and illuminating components, and the existing encoders are all arranged outside the roller assembly, which is cumbersome and has been criticized for a long time.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] The utility model provides a mouse and a magnetic roller module thereof, such as Figure 8 As shown, the mouse includes a magnetic roller module (hereinafter referred to as the roller module) and a shell M, and the roller module is arranged in the shell M.

[0033] like Figures 1 to 7 As shown, the roller module of the present invention comprises: a frame 1, a rotating wheel 2, a stationary wheel 3, a first magnetic object 4, a second magnetic object 55 and an additional component 5.

[0034] The frame body 1 is provided with a frame positioning portion 11 and another frame positioning portion 12 which are opposite to each other. In one embodiment, at least one through hole 13 is further provided.

[0035] The rotating wheel 2 has a rotating shaft 21 (defined as an axial direction, without an element symbol) and a first outer wheel surface 201 and a second outer wheel surface 202 facing each other. The rotating shaft 21 passes through the rotating wheel 2 in the axial direction, and the two ends of the rotating shaft 21 protrude from the first and second outer wheel surfaces 201 and 202 respectively. A rotating sheet 26 is fixedly provided (fixedly arranged) on the first outer wheel surface 201. The rotating sheet 26 has a hollow portion 261. The inner edge of the rotating sheet 26 corresponding to the hollow portion 261 protrudes inwardly with a plurality of inner protruding teeth 262. The second outer wheel surface 202 is concavely provided with a first recessed chamber 23.

[0036] The present invention does not limit the fixing method of the rotating plate 26. In this embodiment, a plurality of first side concave teeth 22 are arranged around the second outer wheel surface 202 in a circle, so that the rotating plate 26 is fixed to the second outer wheel surface 202 by locking each inner convex tooth 262 with each first side concave tooth 22.

[0037] The stationary wheel 3 has a second recessed chamber 31 and an axis positioning portion 321. In one embodiment, the stationary wheel 3 can be a cover-shaped wheel, so it has a cover edge 301 and the second recessed chamber 31 serving as a cover-shaped space. A first wheel axle 32 protrudes axially in the second recessed chamber 31. The first wheel axle 32 is a hollow shaft with a hollow portion, and the hollow portion of the first wheel axle 32 becomes the axis positioning portion 321.

[0038] The stationary wheel 3 is stationarily disposed on the frame 1. The stationary wheel 3 is fixed with a stationary plate 34, and a plurality of externally protruding teeth 342 protrude outwardly from the outer periphery of the stationary plate 34. The present invention does not limit the fixing method of the stationary plate 34. In this embodiment, a plurality of second side concave teeth 311 surrounding each other in a circle are disposed on the cover mouth edge 301, so that each externally protruding tooth 342 is engaged with each second side concave tooth 311, so that the stationary plate 34 is fixed to a wheel surface of the stationary wheel 3 corresponding to the cover mouth edge 301, and the stationary plate 34 covers the corresponding second concave chamber 31. In addition, the stationary plate 34 may also have a hollow portion 341 to allow one end portion of the aforementioned first wheel shaft 32 to be fixed as shown in FIG. Figure 4 As shown, the shaft positioning portion 321 protrudes out and is exposed.

[0039] The present invention also does not limit how the stationary wheel 3 is stationarily disposed on the frame 1. In this embodiment, a clamping block 33 is disposed on the other wheel surface of the stationary wheel 3, and the aforementioned other frame positioning portion 12 is a clamping structure that can clamp the clamping block 33, so that the stationary wheel 3 is constrained by the frame 1 and cannot rotate relative to the frame 1.

[0040] The two ends of the rotating shaft 21 are rotatably overlapped with the frame positioning portion 11 and rotatably inserted into the shaft positioning portion 321, respectively, so that the rotating wheel 2 is bridged between the frame positioning portion 11 and the shaft positioning portion 321, and the rotating wheel 2 can rotate relative to the stationary wheel 3. It should be noted that at this time, the stationary wheel 3 is hung outside the rotating wheel 2 on the first outer wheel surface 201, and the stationary sheet body 34 is appropriately located in the hollow portion 261 of the rotating sheet body 26 and is coaxially arranged with each other, and each outer protruding tooth 342 and each inner protruding tooth 262 are spaced and opposite to each other.

[0041] The first magnetic object 4 is disposed in the second recessed chamber 31 of the stationary wheel 3 and is covered by the stationary plate 34 . The stationary plate 34 is further magnetically attracted by the first magnetic object 4 and conducts magnetism, so that the outer protruding teeth 342 of the stationary plate 34 magnetically attract the inner protruding teeth 262 of the rotating plate 26 .

[0042] Thus, as long as the user turns the rotating wheel 2, a better scale feel will be generated because the outer protruding teeth 342 magnetically attract the inner protruding teeth 262. It should also be noted that due to the magnetic attraction between the outer protruding teeth 342 and the inner protruding teeth 262, when the user quickly turns the rotating wheel 2, the rotating wheel 2 can rotate several times at a time and will not stop rotating after a few turns.

[0043] The additional component 5 includes a circuit board 51, a Hall sensor 511, a second wheel shaft 53 and a second magnetic object 55, and in one embodiment, at least one light emitting element 512. The circuit board 51 is fixed to the frame 1, and the Hall sensor 511 is arranged on the circuit board 51; the second wheel shaft 53 is coaxially wrapped around the rotating shaft 21 in the aforementioned first recessed chamber 23 of the rotating wheel 2; as for the second magnetic object 55 (the polarity of the magnetic pole is the south pole and the north pole respectively), it is arranged on the second wheel shaft 53 in the first recessed chamber 23, and the Hall sensor 511 is arranged as Figure 7 The second magnetic object 55 is shown to generate magnetic induction at one end of the corresponding rotating shaft 21, for example, the Hall sensor 511 and the aforementioned end of the rotating shaft 21 can be linearly opposite to each other along the aforementioned axial direction, and the second magnetic object 55 at this time surrounds the rotating shaft 21 to produce a better magnetic induction effect. Among them, the circuit board 51 (at least having an encoding circuit), the Hall sensor 511 and the second magnetic object 55 are combined into a magnetic induction encoder (without component symbols).

[0044] The present invention does not limit how the second magnetic object 55 is disposed on the second wheel shaft 53. In this embodiment, the second magnetic object 55 is disposed on the second wheel shaft 53 as follows: Figure 4 and Figure 6 As shown, a groove 531 in the shape of a ring is formed in an axially recessed manner at one end of the second wheel shaft 53 and surrounds the rotating shaft 21 . The second magnetic object 55 in the shape of a ring can be embedded and fixed in the groove 531 .

[0045] It should be noted that the second wheel shaft 53 and the second magnetic object 55 jointly occupy a partial space in the aforementioned first recessed chamber 23 .

[0046] Thus, since the rotating wheel 2 leaves a special space for the first recessed chamber 23, the roller module of the present invention can also be equipped with an additional component 5 in a limited space; furthermore, by means of the additional magnetic induction encoder (one of the functions of the additional component 5), the roller module of the present invention also has the effect of an encoder.

[0047] The additional component 5 may further include at least one light-emitting element 512 as mentioned above. The present invention does not limit the number of the light-emitting elements 512. In this embodiment, two light-emitting elements 512 are arranged on the circuit board 51, and the rotating wheel 2 includes a light-guiding wheel body 24 that can guide light. The light-guiding wheel body 24 has the aforementioned rotating shaft 21, the first outer wheel surface 201 and the second outer wheel surface 202. The light emitted by each light-emitting element 512 first passes through the two through holes 13, and then is projected into the remaining space of the first recessed chamber 23 (the remaining space occupied by the second wheel shaft 53 and the second magnetic object 55). The light projected by the two light-emitting elements 512 is guided through the light-guiding wheel body 24, so that the rotating wheel 2 of the roller module of the present invention can also have a light-guiding effect (another function of the additional component 5), so as to utilize the light-guiding to allow the light-guiding wheel body 24 to transmit light to the outside.

[0048] In order to allow only a specific portion of the light guide wheel body 24 to transmit light to the outside, the roller module of the utility model further includes a light shielding sheet 28, which is attached to the second outer wheel surface 202 of the light guide wheel body 24, so that the light shielding sheet 28 only partially covers the second outer wheel surface 202, and the aforementioned rotating sheet body 26 also only partially covers the first outer wheel surface 201, and at the same time, a plurality of light shielding sheets 28 are arranged around the outer wheel of the light guide wheel body 24. Figure 7 A light shielding rubber ring 29 is shown, so that only an annular portion of the rotating wheel 2 adjacent to the outer circumference can transmit light through the light guide.

[0049] Thus, the utility model has the effect of squeezing a magnetic attraction structure that can produce a better scale feel and an additional component 5 that can be combined into a magnetic induction encoder into the limited space of the roller module. In one embodiment, the additional component 5 can also have a light-guiding effect.

[0050] It should also be noted that the rotating sheet 26 and the stationary sheet 34 are both thin sheets with a thickness of 0.3 mm to 0.8 mm, so the space occupied by the rotating sheet 26 and the stationary sheet 34 can be reduced to a certain extent.

[0051] like Figure 8 The mouse of the present invention is shown in FIG. 1 . The housing M of the mouse has a receiving space M1 . The roller module is received in the receiving space M1 . The rotating wheel 2 is partially exposed outside the housing M. The frame 1 is fixed to the housing M.

[0052] In summary, the mouse and its magnetic roller module of the utility model can achieve the expected purpose of use and solve the deficiencies of the prior art, so a patent utility model is proposed. The above-mentioned embodiments are only preferred embodiments for fully illustrating the utility model, and the protection scope of the utility model is not limited thereto. Equivalent substitutions or changes made by technicians in this technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the utility model shall be subject to the claims.
