1. Technical Field
The present disclosure relates to a pointing device for notebook computers.
2. Description of Related Art
Notebook computers include a pointing device, such as a touchpad. The pointing device includes an enclosure for mounting a touch panel. However, the touch panel cannot rebound when it is operated.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
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.”
The mounting panel 10 includes a panel body 11. The panel body 11 defines an opening 111 for receiving the touch panel 30. The mounting panel 10 further includes a positioning portion 12. The positioning portion 12 includes a bottom portion 13 extending from an edge of the opening 111 and two positioning arms 15 extending from the bottom portion 13. Each positioning arm 15 includes an arm body 151 and a positioning flange 153 extending from the arm body 151. The bottom portion 13 is substantially parallel to the touch panel 30. The arm body 151 is slanted and extends from the bottom portion 13. The mounting panel 10 further includes two resisting tabs 17 extending inward from two edges of the opening 111. Each resisting tab 17 is L-shaped and is substantially parallel to the touch panel 30. The two positioning arms 15 are located between the two resisting tabs 17. The mounting panel 10 further includes an associating tab 19 extending inward from an edge of the opening 111.
The touch panel 30 includes an outer panel 31 and an inner panel 33 mounted to the outer panel 31. The inner panel 33 includes a main body 331 attached to the outer panel 31, a connector 333 extending from the main body 331, and a sensor 335 extending from the main body 331. The cross section of the main body 331 is less than that of the outer panel 31 taken along a plane substantially parallel to the panel body 11. The main body 331 defines a side edge 3311 substantially perpendicular to the panel body 11.
The touch panel 30 is pressed and the main body 331 moves down. The two positioning arms 15 are deformed. The two resisting tabs 17 resist the main body 331 when the main body 331 moves down to a position, thereby preventing the main body 331 from moving down. The associating tab 19 contacts the sensor 335 when the main body 331 is in the position. When the touch panel 30 is free, the two positioning arms 15 rebounds to enable the main body 331 to be in the original position.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
