DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1, an exemplary embodiment of a computer mouse includes an upper shell 10, a lower shell 20 mounted to a bottom of the upper shell 10, a first button 30, and a second button 40.
Referring to FIGS. 2 to 4, the upper shell 10 includes an arc-shaped top plate 12, a first side plate 14 extending down from a first side of the top plate 12, and a second side plate 16 extending down from a second side of the top plate 12 opposite to the first side. Mounted on the top plate 12 are a right mechanical button 122, a left mechanical button 120, and a scrolling wheel 124 between the right mechanical button 122 and the left mechanical button 120, at a front end of the top plate 12.
The first side plate 14 defines an opening 140 therein, adjacent to a front end of the first side plate 14. Two first blocks 17 protrude from an inner surface of the first side plate 14, at top and bottom sides of a rear end of the opening 140. Each first block 17 defines a C-shaped first pivot slot 172. Two slanted guiding surfaces 174 are formed at opposite sides bounding an opening of the first pivot slot 172. The second side plate 16 defines an opening 160 therein, adjacent to a front end of the second side plate 16. Two second blocks 18 protrude from an inner surface of the second plate 16, at top and bottom sides of a rear end of the opening 180. Each second block 18 defines a C-shaped second pivot slot 182. Two slanted guiding surfaces 184 are formed at opposite sides bounding an opening of the second pivot slot 182. An inset bar-shaped portion 162 is formed in a front end of the opening 160. A depressed semicircular avoiding groove 16 is defined in the second side plate 16, adjacent to the front end of the opening 160.
The first button 30 includes a flat base plate 32 and an arc-shaped side plate 34. The base plate 32 includes a front end and a rear end opposite to the front end. The side plate 34 is connected to the front end and the rear end. A distance between the base plate 32 and the side plate 34 gradually increases from the rear end towards the front end, thereby the side plate 34 forms a raised portion 340, adjacent to the front end. A connecting block 36 extends from the rear end of the base plate 32. Mounted on the connecting block 36 is a pivot post 360 parallel to the base plate 32. An obstructing tongue 35 protrudes from the front end of the base plate 32, away from the rear end of the base plate 32.
The second button 40 includes a first plate 42, a second plate 44 opposite to the first plate 42, and a supporting plate 46 perpendicularly connected between the first and second plates 42 and 44. The second plate 44 is substantially arc-shaped, and narrower and shorter than the first plate 42. The first plate 42 is longer than the supporting plate 46. An engaging portion 48 is formed at a rear end of the first plate 42. Two posts 420 perpendicularly protrude from top and bottom ends of the engaging portion 48. An arc-shaped operating portion 422 protrudes from a front end of the first plate 42, opposite to the second plate 44.
Referring to FIG. 5, in assembly, the first button 30 is accommodated in the upper shell 10, with the side plate 34 exposed from the opening 140 of the first side plate 14. The pivot post 360 of the first button 30 passes through the opening between the guiding surfaces 174 of the first blocks 17, to rotatably engage in the first pivot slots 172 of the first blocks 17. The base plate 32 is located inside the upper shell 10, and the obstructing tongue 35 resists against the inner surface of the first side plate 14. Therefore, the first button 30 rotatably attaches to the first side plate 14 about the pivot post 360. The obstructing tongue 35 can prevent the first button 30 from rotating out of the upper shell 10 through the opening 140, because of engagement between the obstructing tongue 35 and the inner surface of the first side plate 14.
The second button 40 is accommodated in the upper shell 10, with the front end of the first plate 42 exposed from the opening 160. The posts 420 of the second button 40 pass through the opening between the guiding surfaces 184, to rotatably engage in the second pivot slots 182 of the second blocks 18. The second plate 44 is located in the upper shell 10, and the first plate 42 covers the opening 160. The front end of the first plate 42 resists against an outer surface of the inset portion 162 of the second side plate 16. The operating portion 422 faces the avoiding groove 16.
Referring to FIGS. 6 and 7, in use, if a user needs to achieve the function of a shift button of a keyboard, the user can press the raised portion 340 of the first button 30 on the mouse to rotate the first button 30 inwards relative to the upper shell 10, causing the base plate 32 of the first button 30 to press a corresponding inner structure of the mouse to activate the shift button function of the keyboard. If the user needs to achieve the function of a ctrl button of the keyboard, the user can operate the operating portion 422 of the second button 40, to rotate the second button 40 outwards relative to the upper shell 10, causing the engaging portion 48 to rotate inwards relative to the upper shell 10 to press a corresponding inner structure of the mouse to activate the ctrl button function of the keyboard.
In other embodiments, the structure of the second plate 16 is the same as the structure of the first plate 14, correspondingly two first buttons 30 respectively attach to the second plate 16 and the first plate 14. In use, two first buttons 30 can be operated to rotate inwards relative to the shell 10, the base plates 32 press the corresponding inner structures of the mouse to respectively activate the shift button and the ctrl button functions of the keyboard.
The structure of the first plate 14 can be the same as the structure of the second plate 16, correspondingly two second buttons 40 respectively attach to the second plate 16 and the first plate 14. In use, the buttons are operated to rotate outwards relative to the upper shell 10, causing the engaging portions 48 to press the corresponding inner structures of the mouse to respectively activate the shift button and the ctrl button functions of the keyboard.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
