Background

The mouse is used for controlling a cursor on a computer screen and operating the computer. After the first mouse around the world was manufactured from the united states in 1968, the mouse has become an integral part of computer equipment, whether it be text processing, game contests, industrial drawing, design drawing or media production. Early mice used a trackball as a detection of mouse displacement, and with technological progress and to improve the working efficiency, the mice have been gradually changed into a form of displacement detection using an optical or laser module. In addition, to improve the functionality and convenience of the mouse, the mouse has evolved from the earliest wired single-key mouse to the wireless multi-key roller mouse nowadays. In order to meet the operation requirements of different users, various home electronics manufacturers are also producing mice with different shapes according to different industrial requirements or personal preference, and in addition, how to improve the comfort and sensitivity of the mouse keys such as left and right keys, middle keys, and pressing or operation is also becoming more important.

In the current mouse design, the mouse wheel is utilized to perform forward and backward rotation operation (for example, to control the vertical scroll bar of the window operation interface to move up and down) and press triggering operation, however, the existing mouse wheel can only provide a single rolling hand feeling (such as a stepless rolling hand feeling, a click section rolling hand feeling, etc.), and the user cannot adjust the rolling hand feeling by himself. Therefore, when the user needs different rolling hand feeling of the roller, the user must purchase a new mouse additionally, which is costly, thereby greatly limiting the flexibility and operation convenience of the mouse device, and also reducing the working efficiency when using an unsuitable mouse device. Therefore, how to improve the above problems is a focus of attention of those skilled in the art.

As shown in fig. 1 and 2, the mouse device 2 of the present embodiment includes a wheel module 1 and a housing 3. The case 3 of the mouse device 2 has a through hole 4 on its surface to communicate with the internal space of the case 3. The roller module 1 is disposed in the inner space of the housing 3, and a portion of the roller 11 of the roller module 1 extends out of the through hole 4 of the housing 3, such that the portion of the roller 11 is exposed outside the housing 3 for a user to operate. The mouse device 2 is used for controlling the electronic computer by hand operation or holding movement of the user, for example, moving a cursor displayed in a screen or rolling a roller 11 to control the vertical scroll bar of the window operation interface to move up and down. Other embodiments and operation principles of the mouse device 2 for controlling the electronic computer are well known to those skilled in the art, and will not be described herein.

As shown in fig. 2 to 8, the roller module 1 of the present embodiment includes a base 10, a roller 11, a magnetic conductive element 12, a swing arm 13, a driving motor 14, and an actuator 15. The roller 11 is disposed on the base 10, and the roller 11 can freely rotate on the base 10. The magnetic conductive element 12 is disposed at one side of the roller 11, and when the roller 11 rotates according to an external force, the roller 11 drives the magnetic conductive element 12 to rotate at the same time, that is to say, the roller 11 and the magnetic conductive element 12 can rotate synchronously. The swing arm 13 is disposed on the base 10, and the swing arm 13 includes a magnetic element 130, in this embodiment, the swing arm 13 can swing relative to the magnetic element 12, and in the process of swinging the swing arm 13, the swing arm 13 drives the magnetic element 130 to move at the same time, and determines whether a magnetic attraction force is generated between the magnetic element 130 and the magnetic element 12 according to the relative position between the swing arm 13 and the magnetic element 12, so that the roller module 1 switches between different use states (such as a paragraph mode or a fast rolling mode). The drive motor 14 is disposed on the base 10. The actuating member 15 is disposed between the driving motor and the swing arm 13, and the actuating member 15 has a curved surface 150. In the present embodiment, the driving motor 14 can drive the actuating member 15 to rotate, and the curved surface 150 of the actuating member 15 contacts the swing arm 13 during the rotation of the actuating member 15, so that the swing arm 13 swings to different positions along the curved surface 150 of the actuating member 15 relative to the magnetic conductive element 12.

The other detailed construction of the roller module 1 of the present embodiment is further described below.

As shown in fig. 2 to 8, the roller 11 of the present embodiment includes a fixed shaft body 110. The roller 11 is pivotally connected to the base 10 by a fixing shaft 110, so that the roller 11 can freely rotate on the base 10 through the fixing shaft 110. The magnetic conductive element 12 is disposed on one side of the roller 11 by penetrating through the fixed shaft 110 of the roller 11, that is, the magnetic conductive element 12 is coaxially disposed on the fixed shaft 110 of the roller 11, so that the roller 11 and the magnetic conductive element 12 can perform synchronous rotation. In the present embodiment, the magnetic conductive element 12 is, for example, a gear, but the invention is not limited thereto.

As shown in fig. 2 to 8, the drive motor 14 of the present embodiment includes a drive shaft body 140. The actuating element 15 is disposed on the driving shaft 140 of the driving motor 14, and when the driving motor 14 is started, the driving shaft 140 starts to rotate and drives the actuating element 15 to rotate. In the present embodiment, the appearance of the actuator 15 is, for example, a fan-shaped structure, and a side of the fan-shaped structure near the driving motor 14 has a curved surface 150, but the present invention is not limited to the appearance of the actuator 15. In the present embodiment, the driving motor 14 is, for example, a stepper motor, but the invention is not limited thereto.

It should be noted that, in the present embodiment, the fixed shaft 110 of the roller 11 and the driving shaft 140 of the driving motor 14 are parallel to each other, that is, the extending direction of the fixed shaft 110 and the extending direction of the driving shaft 140 are parallel to each other, and in such a structural design, the driving motor 14 is disposed on the base 10 in a transverse manner, so that the usage of the internal space of the housing 3 (as shown in fig. 1) of the mouse device 2 is effectively reduced, and the thin design of the mouse device 2 is facilitated.

As shown in fig. 2 to 8, the swing arm 13 of the present embodiment includes a swing portion 131, a pushing portion 132, and a pivoting portion 133. The pivot portion 133 is connected between the swing portion 131 and the pushing portion 132, and the swing arm 13 is pivoted to the base 10 by the pivot portion 133. The magnetic element 130 is disposed on the swinging portion 131, and determines whether there is a magnetic attraction between the magnetic element 130 and the magnetic conductive element 12 according to a relative position between the swinging portion 131 and the magnetic conductive element 12, for example, the swinging portion 131 is driven to a position corresponding to the magnetic conductive element 12 during the swinging of the swinging arm 13, and at this time, the magnetic element 130 is disposed between the swinging portion 131 and the magnetic conductive element 12, so that a magnetic attraction is generated between the magnetic element 130 and the magnetic conductive element 12 to form a non-contact magnetic levitation section sense. In addition, in the process of driving the actuator 15 to rotate by the driving motor 14, the curved surface 150 of the actuator 15 contacts the pushing portion 132 of the swing arm 13, so that the pushing portion 132 moves along the curved surface 150 of the actuator 15 and drives the swing portion 131 to swing to different positions. In the present embodiment, the magnetic element 130 is embedded on the surface of the swing portion 131 facing the magnetic conductive element 12, but the invention is not limited thereto.

As shown in fig. 2 to 8, the base 10 of the present embodiment includes a bearing 100. The bearing 100 is located between the magnetically permeable element 12 and the actuator 15. The swing arm 13 is pivotally connected to the bearing 100 of the base 10 by a pivot portion 133, so that the swing arm 13 swings rotationally about the bearing 100.

As shown in fig. 2 to 8, the roller module 1 of the present embodiment further includes a bearing housing 16. The bearing sleeve 16 is sleeved on the bearing 100 of the base 10, and when the swing arm 13 is pivoted on the bearing 100 of the base 10 by the pivot portion 133, the bearing sleeve 16 is located between the bearing 100 and the pivot portion 133. In the process of driving the actuating member 15 to rotate by the driving motor 14 and driving the swing arm 13 to swing, the bearing sleeve 16 can effectively prevent the pivot part 133 of the swing arm 13 from directly contacting with the bearing 100 of the base 10 to rub against each other, and under such structural design, the service life of the swing arm 13 can be greatly prolonged, and the swing arm 13 can be smoother and simultaneously reduce the friction sound in the swinging process.

As shown in fig. 2 to 8, the roller module 1 of the present embodiment further includes an elastic member 17. One end of the elastic element 17 is abutted against the pushing portion 132 of the swing arm 13, and the other end of the elastic element 17 is abutted against the base 10. In the process that the driving motor 14 drives the actuating piece 15 to rotate and drives the swing arm 13 to swing, the elastic restoring force of the elastic element 17 is used for helping the swing arm 13 to act, so that the swing arm 13 swings to the target position smoothly. In the present embodiment, the elastic element 17 is, for example, a torsion spring, but the invention is not limited thereto.

As shown in fig. 2 to 8, the roller module 1 of the present embodiment further includes a noise reduction element 18, and the base 10 further includes a first stop protrusion 101 and a second stop protrusion 102. The noise reduction element 18 is connected to the actuator 15 with the first and second stop ledges 101 and 102 facing each other and being located between the drive motor 14 and the actuator 15. In the process that the driving motor 14 drives the actuating member 15 to rotate and drives the swing arm 13 to swing, the actuating member 15 drives the noise reduction element 18 to abut against the first stop protrusion 101 or the second stop protrusion 102, so that the actuating member 15 is positioned at a proper position and does not move any more. In the present embodiment, the noise reduction element 18 is made of a soft material, so that when the noise reduction element 18 abuts against the first stop protrusion 101 or the second stop protrusion 102, almost no sound occurs, and the sound generated in the process of driving the actuator 15 to rotate by the driving motor 14 and driving the swing arm 13 to swing is effectively reduced.

The detailed operation of the roller module of this embodiment is further described below.

When the user wants to switch the roller module 1 from the use state of the paragraph mode shown in fig. 2, 4 and 5 to the use state of the quick roll mode shown in fig. 6,7 and 8, the user starts the driving motor 14 to drive the actuator 15 to rotate in the first direction D1, during the rotation of the actuator 15 in the first direction D1, the curved surface 150 of the actuator 15 contacts the pushing portion 132 of the swing arm 13, the pushing portion 132 of the swing arm 13 moves along the curved surface 150 of the actuator 15, so that the swing arm 13 swings in the counter-clock direction and drives the swing portion 131 to swing from the first position P1 to the second position P2, and during the movement of the pushing portion 132 along the curved surface 150 of the actuator 15, the pushing portion 132 compresses the elastic element 17, and at the same time, the actuator 15 drives the noise reduction element 18 to move from the position abutting against the first stop boss 101 to the position abutting against the second stop boss 102.

As mentioned above, when the swing portion 131 of the swing arm 13 is located at the second position P2, the magnetic element 130 located at the swing portion 131 is far away from the magnetic conductive element 12, and the magnetic element 130 is completely separated from the range that can be sensed by the magnetic conductive element 12 at the second position P2, so that there is no magnetic attraction between the magnetic element 130 and the magnetic conductive element 12, and the roller module 1 is further switched from the use state of the paragraph mode to the use state of the fast rolling mode. In the use state of the roller module 1 in the fast rolling mode, the magnetic conductive element 12 is not affected by any resistance generated by the magnetic attraction force, so that the roller 11 can rotate rapidly without generating a sectional sense in the process of rotating.

When the user wants to switch the roller module 1 from the use state of the quick-rolling mode shown in fig. 6, 7 and 8 to the use state of the paragraph mode shown in fig. 2, 4 and 5, the user starts the driving motor 14 to drive the actuator 15 to rotate in the second direction D2 opposite to the first direction D1, and during the rotation of the actuator 15 in the second direction D2, the elastic restoring force generated by the elastic element 17 pushes the pushing portion 132 of the swing arm 13 to move along the curved surface 150 of the actuator 15, so that the swing arm 13 swings in the clockwise direction and drives the swinging portion 131 to swing from the second position P2 to the first position P1, at the same time, the actuator 15 drives the noise reduction element 18 to move from the position abutting against the second stop protrusion 102 to the position abutting against the first stop protrusion 101, and when the actuator 15 abuts against the first stop protrusion 101, the curved surface 150 of the actuator 15 is separated from the pushing portion 132 contacting the swing arm 13.

As mentioned above, when the swing portion 131 of the swing arm 13 is located at the first position P1, the magnetic element 130 and the magnetic conductive element 12 located on the swing portion 131 correspond to each other, and the magnetic element 130 is located within a range that can be sensed by the magnetic conductive element 12 at the first position P1, so that the magnetic attraction force is provided between the magnetic element 130 and the magnetic conductive element 12, and the roller module 1 is further switched from the use state of the fast rolling mode to the use state of the paragraph mode. In the usage state of the roller module 1 in the paragraph mode, since the magnetic conductive element 12 and the roller 11 are coaxially disposed, and the magnetic conductive element 12 is influenced by the resistance generated by the magnetic attraction force, the roller 11 generates paragraph sense in the rotation process, that is, in the case that the magnetic conductive element 12 is a gear, the gear and the magnetic element 130 are mutually induced to generate magnetic attraction force, and the tooth-shaped outer surface of the gear is matched with the change of wave crest and wave trough, so that the roller 11 generates clear paragraph sense when rotating.

It should be noted that, as shown in fig. 2,4 and 5, when the roller module 1 is in the use state of the paragraph mode, the elastic restoring force generated by the elastic element 17 abuts against the pushing portion 132 (as shown in fig. 4) of the swing arm 13, so that the swing portion 131 of the swing arm 13 abuts against the stop plate 103 extending from the base 10, and the swing portion 131 of the swing arm 13 is located at the first position P1 opposite to the magnetic conductive element 12. As shown in fig. 6,7 and 8, when the roller module 1 is in the use state of the fast rolling mode, the curved surface 150 of the actuating member 15 and the pushing portion 132 of the swing arm 13 abut against each other, and the actuating member 15 drives the noise reduction element 18 to abut against the second stop portion 102, so that the swing portion 131 of the swing arm 19 is positioned at the second position P2 far from the magnetic conductive element 12.

In summary, in the mouse device of the embodiment of the invention, the roller module drives the actuator to rotate by the driving motor, and in the process of rotating the actuator, the curved surface of the actuator contacts the swing arm, so that the swing arm swings to different positions along the curved surface of the actuator relative to the magnetic conductive element, and whether the magnetic attraction force is generated between the magnetic element and the magnetic conductive element is determined according to the relative position between the swing arm and the magnetic conductive element, so that the roller module changes between the paragraph mode or the fast rolling mode. In addition, through the structural design of the noise reduction element and the bearing sleeve, the roller module is smoother in the operation process of switching the use mode state and simultaneously reduces the noise.
