Abstract

A mouse device includes a housing, a keyswitch, a swing arm, a wheel seat, and a wheel. The housing includes a bottom board. The keyswitch is located over the bottom board and includes a button. The swing arm includes a pivotal portion and first and second extending portions. The pivotal portion is pivotally connected to the bottom board. The first extending portion is connected to the pivotal portion and abuts against the button. The second extending portion is connected to the pivotal portion. The wheel seat is located over the bottom board and configured to laterally swing toward the second extending portion to move the second extending portion, so as to rotate the swing arm to press the button by the first extending portion. The swing arm is located at a side of the wheel seat. The wheel is rotatably disposed in the wheel seat.

First claim

1 . A mouse device, comprising:
a housing comprising a bottom board; a keyswitch located over the bottom board and comprising a button; a swing arm comprising:
a pivotal portion pivotally connected to the bottom board;
a contact point contacting the button; and
a trigger point, wherein a distance from the contact point to a rotation axis of the swing arm is greater than a distance from the trigger point to the rotation axis;
a wheel seat located over the bottom board and configured to laterally swing toward the swing arm to force the trigger point, so as to rotate the swing arm to press the button by the contact point, wherein the swing arm is located at a side of the wheel seat; and a wheel rotatably disposed in the wheel seat.

2 . The mouse device of claim 1 , wherein the swing arm abuts against the wheel seat.

3 - 4 . (canceled)

5 . The mouse device of claim 1 , wherein the wheel seat comprises a first magnet, the swing arm comprises a second magnet, and identical poles of the first magnet and the second magnet are opposite to each other.

6 . The mouse device of claim 1 , further comprising a position-returning member disposed at a side of the swing arm away from the wheel seat and configured to return the swing arm toward the wheel seat.

7 . The mouse device of claim 6 , wherein the housing further comprises a blocking wall disposed on the bottom board, the swing arm is located between the wheel seat and the blocking wall, and the position-returning member is disposed between the swing arm and the blocking wall.

8 . The mouse device of claim 1 , wherein the keyswitch and the wheel seat are located at an identical side of the swing arm.

9 . The mouse device of claim 1 , wherein the housing further comprises a supporting structure disposed on the bottom board and comprising two retaining walls, the wheel seat comprises an extending pillar, and the extending pillar is retained between the two retaining walls.

10 . The mouse device of claim 9 , wherein the extending pillar comprises an insert piece, an accommodating groove and an insertion groove communicated to each other are formed between the two retaining walls, the accommodating groove accommodates a part of the extending pillar, and the insertion groove is located between the accommodating groove and the bottom board and configured to be inserted by the insert piece.

11 . The mouse device of claim 10 , wherein when the insert piece is located outside the insertion groove, the extending pillar is rotatably retained between the two retaining walls, and when the insert piece inserts into the insertion groove, the insert piece is engaged between two inner walls of the insertion groove.

12 . The mouse device of claim 10 , wherein a junction between the accommodating groove and the insertion groove has a chamfered structure.

13 . The mouse device of claim 1 , further comprising:
another keyswitch located over the bottom board and comprising another button; and another swing arm comprising another pivotal portion pivotally connected to the bottom board; wherein the another swing arm is located at another side of the wheel seat, and the side and the another side of the wheel seat are opposite to each other.

14 . The mouse device of claim 1 , wherein the swing arm further comprises:
a first extending portion connected to the pivotal portion, wherein the contact point is on the first extending portion; and a second extending portion connected to the pivotal portion, wherein the trigger point is on the second extending portion.
