1. Technical Field
The present disclosure relates to slide-type button assemblies and, particularly, to a slide-type button assembly used in a portable electronic device.
2. Description of Related Art
Slide-type button assemblies have been widely used in portable electronic devices such as mobile phones and personal digital assistants (PDAs).
A typical slide-type button assembly includes a sliding member slidably mounted in a cavity defined in a housing of a portable electronic device. The sliding member can slide between at least two positions. Different positions correspond to different functions. Thus a user can select different functions by sliding the sliding member.
However, contaminants, e.g., water and dust, may enter into space between the sliding member and the cavity, thus the portable electronic device.
Therefore, there is room for improvement within the art.
Many aspects of the slide-type button assembly can be better understood with reference to the following drawings. These drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present slide-type button assembly. Moreover, in the drawings like reference numerals designate corresponding sections throughout the several views.
The present slide-type button assembly is suitable for use in a portable electronic device, e.g., mobile phone and personal digital assistant (PDA).

The body member 10 includes a bottom wall 11 and a sidewall 12 perpendicular with the bottom wall 11. The sidewall 12 defines an opening 121. The switch 30 is fastened to the bottom wall 11, facing the opening 121. The body member 10 further includes an assembled portion 17. The assembled portion 17 includes two stopping blocks 13 and two resisting blocks 14. The two stopping blocks 13 perpendicularly and symmetrically protrude from an interior side of the sidewall 12, adjacent to the opening 121. The two stopping blocks 13 are for abutting against the sliding member 40. The two resisting blocks 14 protrude from the bottom wall 11 adjacent to the opening 121. One end of each resisting block 14 forms an extending end 142 facing a corresponding stopping block 13 and slightly angled towards the sidewall 12, thus a cross section of each resisting block 14 is a tilted L-shape. The elastic members 50 are respectively disposed between the sliding members 40 and the resisting blocks 14. The elastic members 50 can compress the sliding member 40 to tightly abut against an inner side of the sidewall 12, thus efficiently avoid any space exposed between the sliding member 40 and the sidewall 12 (
The cover member 20 includes a cutout 21 defined therethrough and corresponding to the opening 121. The cutout 21 and the opening 121 cooperatively surround a channel through which the sliding member 40 is inserted into the body member 10.
The switch 30 has a plurality of gear positions. In this embodiment, the switch 30 has two gear positions. Each gear position corresponds to one function of the portable electronic device. The switch 30 includes a main body 31 and a dialing post 32 swinging relative to the main body 31 driven by the sliding member 40.
The sliding member 40 includes a main portion 41, two resisting portions 42, two projections 43, an operating portion 44, and two posts 45. The main portion 41 includes a first surface 411 and a second surface 412 opposite to the first surface 411. The two resisting portions 42 perpendicularly protrude from both ends of the main portion 41. The two posts 45 respectively protrude from one resisting portion 42, slightly angled away from the main portion 41 (

In use, an external force is applied on the operating portion 44 until the the sliding member 40 is slid towards one stopping block 13. One elastic member 50 is compressed, and the other elastic member 50 is stretched. The sliding member 40 is continued to be slid until one resisting portion 42 are for abutting against a corresponding stopping block 13. At this time, the dialing post 32 of the switch 30 has been turned to a gear position. It is to be understood, if the sliding member 40 is slid to another direction, the dialing post 32 of the switch 30 can be turned to another gear position.
The slide-type button assembly 100 can effectively protect water or dust from entering into the body member 10, using the sliding member 40 compressed by the two elastic members 50.
It is to be understood, however, that even through 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 sections 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.
