## Background
BACKGROUND
1. Technical Field
The present disclosure relates to mice, and particularly to a multifunctional mouse.
2. Description of Related Art
Universal Serial Bus (USB) interfaces are widely used in computers. When a portable electronic device such as a digital camera or an MP3/MP4 player is connected to a computer by a USB interface, the portable electronic device and the computer can transmit data to each other by the USB interface. Furthermore, the computer can also charge the battery of the portable electronic device by the USB interface.
Mice are often used to operate computers. Nowadays, many mice can also be connected to computers by USB interfaces. Generally, when a mouse is connected to a USB interface, the USB interface cannot be used to charge a battery.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
FIG. 1 and FIG. 2 schematically show a mouse 100, according to an exemplary embodiment in which the mouse 100 is a combination mouse and battery charger. As shown in FIG. 5, the mouse 100 can be connected to a Universal Serial Bus (USB) interface 91 of a computer 90 to operate the computer 90. The mouse 100 includes a housing 10, a circuit board 20, a supporting mechanism 30, and a battery chamber 40. The circuit board 20, the supporting mechanism 30, and the battery chamber 40 are all received in the housing 10.
The housing 10 includes a cover 12 and a main body 14. The cover 12 is a curved panel. The main body 14 includes a base panel 140 and an assembling frame 141. The base panel 140 is a planar board, and the assembling frame 141 is perpendicularly connected to a periphery of the base panel 140. The shape and size of the assembling frame 141 corresponds to the shape and size of the cover 12, such that the cover 12 can be assembled to the assembling frame 141.
The circuit board 20 is mounted on the base panel 140 and is surrounded by the assembling frame 141. The circuit board 20 includes a conventional USB mouse operating circuit 211 and a USB connector 212, and further includes a conventional charging circuit 213 and at least one first charging connector 22. The USB connector 212 can be connected to the USB interface 91 of the computer 90. The USB mouse operating circuit 211 and the charging circuit 213 are both electrically connected to the USB connector 212. The first charging connector 22 is a bent elastic sheet that perpendicularly extends from the top surface of the circuit board 20 and is electrically connected to the charging circuit 213. When the USB connector 212 is connected to the USB interface 91, both the USB mouse operating circuit 211 and the charging circuit 213 can be connected to the computer 90 by the USB connector 212 and the USB interface 91.
The supporting mechanism 30 includes a supporting board 31, a holding frame 32, and a fixing member 34. The supporting board 31 is a planar sheet perpendicularly connected to the assembling frame 14 and positioned parallel with the base panel 140 and the circuit board 20. One side of the supporting board 31 is positioned adjacent to the first charging connector 22. The holding frame 32 is an approximately U-shaped frame formed on the supporting board 31 and opening towards a side of the supporting board 31. The fixing member 34 includes a connecting protrusion 342 and a fixing component 344. The connecting protrusion 342 is formed on the supporting board 31 and positioned adjacent to the opening of the holding frame 32. The fixing component 344 is a bar rotatably mounted on the connecting protrusion 342. The fixing component 344 can be rotated to block the opening of the holding frame 32.
The battery chamber 40 includes a battery tray 42, a receiving frame 44, and at least one second charging connector 48. The battery tray 42 is a planar board, which can be received in the holding frame 32. The receiving frame 44 is an approximately U-shaped frame formed on the battery tray 42. Also referring to FIG. 3 and FIG. 4, a battery 50 can be received in the receiving frame 44. The second charging connector 48 is a bent elastic sheet mounted on the receiving frame 44 and configured to correspond to the battery 50 and the first charging connector 22. When the battery 50 is received in the receiving frame 44, the poles of the battery 50 can be electrically connected to the second charging connector 48. When the battery tray 42 is received in the holding frame 32 and the receiving frame 44 and the holding frame 32 are positioned to open towards a same direction, the second charging connector 48 can be electrically connected to the first charging connector 22.
The mouse 100 can be used to operate the computer 90, and can also be used to charge the battery 50 while the mouse 100 is connected to the computer 90. When the mouse 100 is used as a battery charger, the battery tray 42 is received in the holding frame 23. The receiving frame 44 and the holding frame 32 are positioned to open towards a same direction, and the second charging connector 48 contacts the first charging connector 22 and is electrically connected to the first charging connector 22. The battery 50 is then received in the receiving frame 44, and the poles of the battery 50 contact the second charging connector 48 and is electrically connected to the second charging connector 48. The fixing component 344 is rotated to block the receiving frame 44 and the battery 50. Thus, the battery 50 is held in the receiving frame 44, and the battery chamber 40 is held in the holding frame 32. Finally, the cover 12 is assembled to the assembling frame 141.
In use, the assembled mouse 100 with the battery 50 received therein is connected to the computer 90. The USB connector 212 is connected to the USB interface 91, such that the USB mouse operating circuit 211 and the charging circuit 213 are both connected to the USB interface 91. The USB mouse operating circuit 211 can be used to operate the computer 90 by conventional methods. Furthermore, the battery 50 is synchronously connected to the USB interface 91 by the second charging connector 48, the first charging connector 22, and the charging circuit 213. Thus, the computer 90 can charge the battery 50 during operation of the mouse 100.
When the battery 50 is fully charged, the cover 12 is detached from the main body 14, the fixing member 344 is rotated to release the battery chamber 40 and the battery 50. The battery chamber 40 and the battery 50 can be removed together from the opening of the holding frame 32, and the battery 50 is then removed from the battery chamber 40 via the opening of the battery chamber 40. In this way, the first charging connector 22, the second charging connector 48, and the battery 50 can be protected from damages due to friction generated between each other.
Apparently, the mouse 100 can also be used without receiving the battery chamber 40 and/or the battery 50 therein. The supporting mechanism 30 can be integrated with the housing 10.
The mouse 100 can be used to operate the computer 90 as a conventional USB mouse, and can also be used to charge the battery 50 during use. Thus, the mouse 100 is multifunctional and can take full advantage of the USB interface 91 connected thereto.
It is to be further understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
