A waterproof structure for a button, comprising a casing (1), a button (2) and a flexible piece (3); the flexible piece (3) is located on the casing (1); the button (2) is movably connected to the casing (1) and contacts the flexible piece (3); the flexible piece (3) is integral with the casing (1) and comprises a tubular structure (31) provided with a flexible wall (32), the flexible wall (32) being an arc-shaped structure and protruding into the tubular structure (31). The dedicated arc-shaped flexible wall is designed to provide flexible travel required for breakover of the button, so as to satisfy a tensile deformation requirement when the button (2) is depressed. In addition, the flexible piece (3) is an interior part of the product and is not readily subject to casing limitations; the flexing length of the flexible piece can be set adjustably, effectively improving the feel when touching the button (2). Moreover, the button (2) is an independent element, and the shape and color thereof can be flexibly designed, thus better satisfying customer requirements and product design requirements. |
