1 is a perspective view of a mouse according to an embodiment of the present invention. Figure 2 is a partial side elevational view of the pivoting structure of Figure 1. 3 is a perspective view of the battery cover of FIG. 1 closed to the main body. 4 is a partial side elevational view of the pivoting structure of FIG. 3. Referring to FIG. 1 , the mouse 100 of the present embodiment includes a main body 110 and a pivot structure 120 . The main body 110 has an opening 112 through which a user can insert a battery (not shown) into the main body 110.

Referring to FIG. 2 at the same time, the pivot structure 120 includes a battery cover 122 and a torsion spring 124. The battery cover 122 is pivotally disposed on the main body 110 with the first position P1 of the main body 110 as an axis, and is unfolded or closed by the rotation of the main body 110. Opening 112 (shown in Figure 1). The torsion spring 124 is pivotally disposed on the main body 110 with the second position P2 of the main body 110 as an axis.

It should be noted that the first spring arm 124a of the torsion spring 124 is fixed to the main body 110, and the second spring arm 124b is slidably disposed on the battery cover 122. During the process of transitioning from the battery cover 122 to the main body 110 (as shown in FIGS. 3 and 4) to the main body 110 (as shown in FIGS. 1 and 2), the second spring arm 124b is in the battery. The cover 122 slides to drive the torsion spring 124 to deform. In other words, when the torsion spring 124 and the battery cover 122 are different shafts, if the second spring arm 124b is fixed to the battery cover 122, the overall structure cannot be actuated. Therefore, the second spring arm 124b of the torsion spring 124 is slidably disposed on the battery cover 122, so that the overall structure has sufficient freedom to operate smoothly under the condition that the torsion spring 124 and the battery cover 122 have different axes.

Referring to FIG. 1 and FIG. 2, in the embodiment, the battery cover 122 includes a rotating shaft 122a, a cover 122b, and a connecting portion 122c. The battery cover 122 is pivotally disposed at a first position P1 of the main body 110 by a rotating shaft 122a. The cover 122b is used to cover the opening 112. The connecting portion 122c is connected between the rotating shaft 122a and the lid 122b. When the user wants to close the cover 122b, the cover 112 can be pressed down to the opening 112, and the rotating shaft 122a is rotated in the pivoting direction D to the state shown in FIG. 4, and the cover 112 and the main body are provided.

Referring to FIG. 2 and FIG. 4, it is noted that in the process of the second spring arm 124b approaching the rotating shaft 122a along the sliding groove S, the force arm for biasing the connecting portion 122c with the rotating shaft 122a as a fulcrum is gradually shortened. In other words, as the cover 122b is closer to the fully deployed state, the force force of the upper body 122b decreases as the elastic position of the torsion spring 124 decreases and the second spring arm 124b biases the force arm of the connecting portion 122c. Gradually, it can avoid the user's use troubles caused by the elastic force on the cover 122b. In addition, referring to FIG. 5 , in the embodiment, the main body 110 has the protrusions 114 located at the second position P2 (shown in FIGS. 2 and 4 ), and the torsion springs 124 are sleeved on the protrusions 114 . The pivot is disposed on the main body 110. Referring to FIGS. 2 and 4, the second spring arm 124b has a circular arc-shaped structure C for contacting the connecting portion 122c so as to be smooth when sliding along the connecting portion 122c.

In summary, the torsion spring of the present invention has the first spring arm fixed to the main body and the second spring arm slidably disposed on the battery cover, so that the pivoting structure can be separated from the battery cover by the different axis of the torsion spring. The second spring arm smoothly moves relative to the sliding of the battery cover. With this configuration, the torsion spring does not have to be coaxial with the battery cover and can be disposed in a sufficient space to reduce the difficulty in configuration. In addition, during the deployment of the cover body, the force of the cover body can be gradually reduced by the gradual shortening of the force arm of the second spring arm to the connection portion, so as to avoid the user being too strong due to the cover body. It is elastic and creates discomfort.
