Description

Technical Field

[0001] The utility model relates to a mouse, in particular to a mouse in which a ratcheting force associated with an operating roller is designed with magnetic suction force and can even be switched to a state without ratcheting force. Background Art

[0002] As the input peripherals of data processing systems continue to develop, the mouse is still an indispensable input peripheral for most data processing systems. The mouse is used to perform cursor operations on the display of the data processing system, positioning and clicking functions, and the data processing system follows the amount of rotation of the mouse wheel to execute specific control instructions, such as scrolling windows on the display, zooming in and out of images, or adjusting the volume.

[0003] The scroll wheel of the mouse of the prior art has a concave side, and the concave side wall relative to the circumference of the scroll wheel forms a corrugated surface. The mouse of the prior art is equipped with an interference member that interferes with the scroll wheel to provide a ratchet force related to the operation of the scroll wheel. The interference member interferes with the corrugated surface in the scroll wheel, so that the scroll wheel will present multiple segment senses for each rotation of the scroll wheel. The segment sense of the operation of the scroll wheel can provide a function similar to a scale. However, the scroll wheel structure of the mouse of the prior art that provides a mechanical ratchet force is complex, and its manufacturing cost is also high.

[0004] In addition, the ratchet force associated with the operation of the scroll wheel of the mouse provided by the prior art can be adjusted, that is, the distance between the end of the interference member and the corrugated surface in the scroll wheel can be adjusted, so that the specific control command executed can produce different execution degrees according to the segment sense of the operation of the scroll wheel. For example, when the end of the interference member contacts the corrugated surface in the scroll wheel, the scroll wheel is rotated and each time a segment sense is generated, the data processing system executes to scroll the window on the display by three lines. When the end of the interference member does not contact the corrugated surface in the scroll wheel, the rotation of the scroll wheel is not interfered by the interference member and will continue for a period of time, that is, the scroll wheel rotates in a smooth and segment-free manner, so that the specific control command executed can directly execute the maximum degree of instruction. For example, when the user operates the scroll wheel of the mouse to scroll the window on the display from the top to the bottom, it is not necessary to repeatedly turn the scroll wheel to make it rotate. It only needs to turn the scroll wheel once, and the window on the display can continue to scroll until the window on the display scrolls to the position required by the user and then stops rotating the scroll wheel. However, the adjustment devices for adjusting the ratchet force associated with the operating wheel in the prior art mouse are quite complicated, and the prior art mouse even uses a motor to drive the interference member.

[0025] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0026] See also Figure 1 , Figure 2 and Figure 3 , which is the mouse 1 of the first preferred embodiment of the present utility model. Figure 1 A mouse 1 according to a first preferred embodiment of the present invention is schematically shown in a top view. Figure 2 The mouse 1 of the first preferred embodiment of the present invention is schematically illustrated with a three-dimensional schematic diagram, wherein the internal components and members thereof are shown to show that the second permanent magnetic element 16 is located at the first position. Figure 3 Another three-dimensional schematic diagram schematically illustrates the internal components and members of the mouse 1 of the first preferred embodiment of the present invention to show that the second permanent magnetic element 16 is located at the second position.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the mouse 1 of a preferred embodiment of the present invention comprises a housing 10 , a roller 12 , a first annular permanent magnetic element 14 and a second permanent magnetic element 16 .

[0028] The housing 10 has an opening 100. The housing 10 includes an upper housing 102 and a lower housing 104. The opening 100 is formed on the upper housing 102.

[0029] like Figure 1 As shown, the roller 12 is rotatably fixed in the housing 10. A portion of the roller 12 is exposed outside the opening 100 of the housing 10, so that the user can operate the exposed portion of the roller 12.

[0030] The annular first permanent magnetic element 14 is fixed on the inner wall 122 of the roller 12. The annular first permanent magnetic element 14 is magnetized into a plurality of first polarity magnetic regions (or first magnetic parts, the same below) 142 and a plurality of second polarity magnetic regions (or second magnetic parts, the same below) 144 along the circumferential direction d1. The plurality of first polarity magnetic regions 142 and the plurality of second polarity magnetic regions 144 are arranged alternately. It should be emphasized that the annular first permanent magnetic element 14 is a single element, rather than combining a plurality of permanent magnetic elements into one element.

[0031] The second permanent magnetic element 16 is disposed in the housing 10, so that the second permanent magnetic element 16 generates a magnetic interaction force with any one of the plurality of first polarity magnetic regions 142 and the plurality of second polarity magnetic regions 144. Thus, the mouse 1 of the first preferred embodiment of the utility model utilizes the magnetic interaction force between the second permanent magnetic element 16 and the annular first permanent magnetic element 14 as a ratchet force, so that the user can feel a segmented hand feeling when operating the scroll wheel 12 to rotate.

[0032] Further, such as Figure 2 and Figure 3 As shown, the mouse 1 of the first preferred embodiment of the present invention further comprises an auxiliary fixing member 18. The second permanent magnetic element 16 is fixed on the auxiliary fixing member 18. The auxiliary fixing member 18 can be movably fixed in the housing 10, thereby enabling the second permanent magnetic element 16 to move between the first position and the second position. Figure 2 As shown, when the second permanent magnetic element 16 is located at the first position, the second permanent magnetic element 16 generates a magnetic interaction force with any one of the plurality of first polarity magnetic regions 142 and the plurality of second polarity magnetic regions 144. At this time, the mouse 1 of the first preferred embodiment of the utility model uses the magnetic interaction force between the second permanent magnetic element 16 and the annular first permanent magnetic element 14 as a ratchet force, so that the user can feel the hand when operating the scroll wheel 12 to rotate. Figure 3 As shown, when the second permanent magnetic element 16 is located at the second position, the second permanent magnetic element 16 will not generate magnetic interaction force with any of the plurality of first polarity magnetic regions 142 and the plurality of second polarity magnetic regions 144. At this time, the mouse 1 of the first preferred embodiment of the utility model is switched to a state without ratchet force, so that the user can operate the scroll wheel 12 to rotate without a sense of stoppage, that is, the scroll wheel 12 rotates smoothly without a sense of stoppage.

[0033] In a specific embodiment, if Figure 2 and Figure 3As shown, the auxiliary fixing member 18 is rotatably fixed in the housing 10. The second permanent magnetic element 16 can switch between the first position and the second position following the rotation of the auxiliary fixing member 18.

[0034] In another specific embodiment, the auxiliary fixing member 18 can be slidably or otherwise movably fixed in the housing 10. It should be noted that the structure of the slidable or otherwise movably fixed auxiliary fixing member 18 is not shown in the figure.

[0035] In a specific embodiment, each first polarity magnetic region 142 has a first polarity, for example, Figure 2 , Figure 3 Each second polarity magnetic region 144 has a second polarity opposite to the first polarity, for example, Figure 2 , Figure 3 The second permanent magnetic element 16 is magnetized into a third magnetic region (or third magnetic portion, the same below) 162 and a fourth magnetic region (or fourth magnetic portion, the same below, not marked in FIG. Figure 2 , Figure 3 In other words, the annular first permanent magnetic element 14 has a plurality of first polarity magnetic regions 142 and a plurality of second polarity magnetic regions 144 along the circumferential direction d1, and the plurality of first polarity magnetic regions 142 and the plurality of second polarity magnetic regions 144 are arranged alternately. The third magnetic region 162 has a first polarity, for example, Figure 2 , Figure 3 As shown by the N pole indicated in the figure. The fourth magnetic region has a second polarity, for example, an S pole. In other words, the second permanent magnetic element 16 has a first polarity end (corresponding to the third magnetic region 162, and the polarity is the same as the first polarity magnetic region 142) and a second polarity end (corresponding to the fourth magnetic region, and the polarity is the same as the second polarity magnetic region 144). The second permanent magnetic element 16 is fixed on the auxiliary fixing member 18 so that the third magnetic region 162 faces the annular first permanent magnetic element 14. Continue to refer to Figure 2 and Figure 3, the second permanent magnetic element 16 has an N pole toward the third magnetic zone 162 of the annular first permanent magnetic element 14. When the user operates the roller 12 to rotate and drive the annular first permanent magnetic element 14 to rotate to the second polarity magnetic zone 144 with an S pole at the lowest position, a magnetic attraction force occurs between the third magnetic zone 162 and the second polarity magnetic zone 144 (i.e., the second polarity magnetic zone 144 with an S pole at the lowest position). When the user operates the roller 12 to rotate and drive the annular first permanent magnetic element 14 to rotate to the first polarity magnetic zone 142 with an N pole at the lowest position, a magnetic repulsion force occurs between the third magnetic zone 162 and the first polarity magnetic zone 142 (i.e., the first polarity magnetic zone 142 with an N pole at the lowest position). The magnetic interaction force between the second permanent magnetic element 16 and the annular first permanent magnetic element 14 is used as a ratchet force. In this way, the user will have a segmented feel when operating the roller 12 to rotate.

[0036] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 , which schematically depicts a mouse 2 according to a second preferred embodiment of the present invention. Figure 4 A mouse 2 according to a second preferred embodiment of the present invention is schematically depicted in a top view. Figure 5 The internal components and members of the mouse 2 of the second preferred embodiment of the present invention are schematically depicted in a three-dimensional schematic diagram. Figure 6 The mouse 2 of the second preferred embodiment of the present invention is schematically depicted in a side view, wherein the internal components and members thereof are shown to show that the second permanent magnetic element 26 thereof is located at a first position. Figure 7 Another side view schematically illustrates the internal components and members of the mouse 2 of the second preferred embodiment of the present invention to show that the second permanent magnetic element 26 is located at the second position.

[0037] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the mouse 2 of the second preferred embodiment of the present invention comprises a housing 20 , a roller 22 , a first annular permanent magnetic element 24 and a second permanent magnetic element 26 .

[0038] The housing 20 has an opening 200. The housing 20 includes an upper housing 202 and a lower housing 204. The opening 200 is formed on the upper housing 202.

[0039] like Figure 4 As shown, the roller 22 is rotatably fixed in the housing 20. A portion of the roller 22 is exposed outside the opening 200 of the housing 20. The roller 22 includes a rotation axis 222. The rotation axis 222 extends outward from the rotation center 220 of the roller 22.

[0040] The annular first permanent magnetic element 24 is fixed on the circumference 224 of the rotating shaft 222 of the roller 22. The annular first permanent magnetic element 24 is magnetized along the circumferential direction d2 into a plurality of first polarity magnetic regions 242 and a plurality of second polarity magnetic regions 244. The plurality of first polarity magnetic regions 242 and the plurality of second polarity magnetic regions 244 are arranged alternately. It should be emphasized that the annular first permanent magnetic element 24 is a single element, rather than a plurality of permanent magnetic elements being joined into one element.

[0041] The second permanent magnetic element 26 is disposed in the housing 20, so that the second permanent magnetic element 26 generates a magnetic interaction force with any one of the plurality of first polarity magnetic regions 242 and the plurality of second polarity magnetic regions 244. Thus, the mouse 2 of the second preferred embodiment of the present invention utilizes the magnetic interaction force between the second permanent magnetic element 26 and the annular first permanent magnetic element 24 as a ratchet force, so that the user can feel a step when operating the scroll wheel 22 to rotate.

[0042] Further, if Figure 4 , Figure 5 and Figure 6 As shown in FIG. 2 , the mouse 2 of the second preferred embodiment of the present invention further comprises an auxiliary fixing member 28. The second permanent magnetic element 26 is fixed on the auxiliary fixing member 28. The auxiliary fixing member 28 is movably fixed in the housing 20, thereby enabling the second permanent magnetic element 26 to move between the first position and the second position. Figure 5 and Figure 6 As shown, when the second permanent magnetic element 26 is located at the first position, the second permanent magnetic element 26 generates a magnetic interaction force with any one of the plurality of first polarity magnetic regions 242 and the plurality of second polarity magnetic regions 244. At this time, the mouse 2 of the second preferred embodiment of the utility model uses the magnetic interaction force between the second permanent magnetic element 26 and the annular first permanent magnetic element 24 as a ratchet force, so that the user can feel the hand when operating the scroll wheel 22 to rotate. Figure 7 As shown, when the second permanent magnetic element 26 is located at the second position, the second permanent magnetic element 26 will not generate magnetic interaction force with any of the plurality of first polarity magnetic regions 242 and the plurality of second polarity magnetic regions 244. At this time, the mouse 2 of the second preferred embodiment of the utility model is switched to a state without ratchet force, so that the user can operate the scroll wheel 22 to rotate without a sense of stoppage, that is, the scroll wheel 22 rotates smoothly without a sense of stoppage.

[0043] In a specific embodiment, if Figure 5 , Figure 6 and Figure 7 As shown, the auxiliary fixing member 28 is slidably fixed in the housing 20. The second permanent magnetic element 26 can switch between the first position and the second position following the sliding of the auxiliary fixing member 28.

[0044] In another specific embodiment, the auxiliary fixing member 28 is rotatably or other movably fixed in the housing 20. It should be noted that the structure of the rotatable or other movably fixed auxiliary fixing member 28 is not shown in the figure.

[0045] In a specific embodiment, each first polarity magnetic region 242 has a first polarity, for example, Figure 5 , Figure 6 and Figure 7 Each second polarity magnetic region 244 has a second polarity opposite to the first polarity, for example, Figure 5 , Figure 6 and Figure 7 The S pole is indicated in . Figure 5 As shown, the second permanent magnet element 26 is magnetized into a third magnetic region 262 and a fourth magnetic region 264. The third magnetic region 262 has a first polarity, for example, Figure 5 The fourth magnetic region 264 has a second polarity, for example, Figure 5 The second permanent magnetic element 26 is fixed on the auxiliary fixing member 28 so that the third magnetic region 262 faces the annular first permanent magnetic element 24 .

[0046] When the user operates the roller 22 to rotate and drive the annular first permanent magnetic element 24 to rotate to the second polarity magnetic zone 244 with the S pole at the lowest position, a magnetic attraction force occurs between the third magnetic zone 262 and the second polarity magnetic zone 244 (i.e., the second polarity magnetic zone 244 with the S pole at the lowest position). When the user operates the roller 22 to rotate and drive the annular first permanent magnetic element 24 to rotate to the first polarity magnetic zone 242 with the N pole at the lowest position, a magnetic repulsion force occurs between the third magnetic zone 262 and the first polarity magnetic zone 242 (i.e., the first polarity magnetic zone 242 with the N pole at the lowest position). The magnetic interaction force between the second permanent magnetic element 26 and the annular first permanent magnetic element 214 acts as a ratchet force. In this way, the user will have a segmented feel when operating the roller 22 to rotate.

[0047] Through the above detailed description of the utility model, it can be clearly understood that the ratchet force related to the operation of the scroll wheel of the mouse of the utility model adopts the design of magnetic suction. The scroll wheel structure of the mouse of the utility model is simple. In addition, the magnetic suction force of the mouse of the utility model as the ratchet force can be switched to a state without ratchet force, which is more convenient for the user to operate and improves the user experience.

[0048] Of course, the present invention may have many other embodiments.
