Mouse and its pivoting structure

The present invention relates to a pivoting structure and a mouse therewith, and more particularly to a pivoting structure using a torsion spring and a mouse having the same.

The mouse is a must-have peripheral device for the computer, and the cursor position on the computer screen can be easily controlled by moving the mouse. The wireless mouse does not need to be connected to the computer via a signal cable, and allows the user to operate the wireless mouse without being twisted by the signal cable. Based on the above advantages, the wireless mouse has gradually become a popular computer peripheral device. The wireless mouse is equipped with a radio circuit device such as a transmitting/receiving antenna, a carrier generator, an antenna driving amplifier, a detector, a comparator, and a decoder in the mouse body to utilize the radio wave by the transmitting/receiving antenna. The transfer mode is transmitted to the receiver on the host computer to control the operation of the host computer. The power required for the wireless mouse to operate must be supplied by the battery, so the wireless mouse will have a battery cover to cover the battery installed in the wireless mouse.

It is known that a battery cover is configured such that one end is pivotally connected to a mouse, and the battery cover can be unfolded or closed to the mouse by relative rotation of the mouse. In order to enable the battery cover to be unfolded to the mouse in an automatic pop-up manner, a torsion spring can be placed on the rotating shaft of the battery cover, wherein the two spring arms of the torsion spring are respectively fixed to the mouse and the battery cover to exert the elastic force thereof. The battery cover is automatically deployed to the mouse. However, the rotating shaft of the battery cover must be as close as possible to the outer surface of the mouse to avoid structural interference with the mouse casing when the battery cover is rotated, thereby making the configuration space at the rotating shaft limited, which causes difficulty in the configuration of the torsion spring.

The invention provides a mouse, and the configuration space of the torsion spring of the pivoting structure is sufficient.

The above described features and advantages of the present invention will be more apparent from the following description.

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 to the opening 112 (shown in FIG. 1) by the rotation of the main body 110. The torsion spring 124 includes a first spring body 124a, a second spring body 124b, a first spring arm 124c, a second spring arm 124d, and a third spring arm 124e. The first spring body 124a is pivotally disposed on the main body 110 with the second position P2 of the main body 110 as an axis. The first spring arm 124c is coupled between the first spring body 124a and the second spring body 124b. The second spring arm 124d extends from the first spring body 124a and is fixed to the main body 110. The third spring arm 124e extends from the second spring body 124b and is fixed to the battery cover 122.

It should be noted that in the process of changing from the battery cover 122 to the main body 110 (as shown in FIG. 3 and FIG. 4 ) to the main body 110 (as shown in FIG. 1 and FIG. 2 ), the suspended ceiling The two springs 124b are deformed and displaced. In other words, in the case where the torsion spring 124 and the battery cover 122 are different shafts, if the second spring body 124b is not present and the fixed first spring body 124a is directly connected to the battery cover 122, the overall structure cannot be actuated. Therefore, the second spring body 124b is disposed between the battery cover 122 and the first spring body 124a, 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. The engagement state between the 110s is fixed.

Figure 5 is a partial perspective view of the pivoting structure of Figure 4. Referring to FIG. 5, in detail, the connecting portion 122c of the embodiment has a card slot T, and the third spring arm 124e is a card slot T that is locked to the connecting portion 122c. During the rotation of the rotating shaft 122a in the pivoting direction D by the state shown in FIG. 2 to the state shown in FIG. 4, the third spring arm 124e is driven by the connecting portion 122c, and the torsion spring 124 is deformed. And store the elastic potential energy. Referring to FIG. 3 and FIG. 4, when the user wants to expand the cover 122b, the engagement state between the cover 112 and the main body 110 can be released. At this time, the elastic position energy stored in the torsion spring 124 is released, and the third spring arm 124e of the torsion spring 124 drives the battery cover 122 to be deployed on the main body 110 by elastic force (as shown in FIGS. 1 and 2).

Referring to FIG. 5 , in the embodiment, the main body 110 has a protrusion 114 at a second position P2 (shown in FIG. 2 and FIG. 4 ), and the torsion spring 124 is pivoted in a manner of being disposed on the protrusion 114 . In the body 110. In addition, the third spring arm 124e has a bent structure L for being locked to the connecting portion 122c so as to be fixed to the connecting portion 122c.

In summary, the torsion spring of the present invention has a second spring body connected between the first spring body and the battery cover, and the pivoting structure can be made by the second structure in the case where the torsion spring is different from the battery cover. The displacement and deformation of the spring body are smoothly operated. 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.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
