Problems solved by technology

[0003] However, the above-mentioned existing waterproof structure realizes the waterproof effect through two parts of the sealing ring and the waterproof sheet, so the problem of increasing the number of parts and increasing the cost arises.
Moreover, the existing structure is a waterproof structure dedicated to the rotary knob, which is not suitable for the operation body that can not only be rotated but also pressed.

Embodiment Construction

[0023] Next, specific embodiments of the present invention will be described with reference to the drawings.

[0024] figure 1 It is a perspective view of an electronic device to which the present invention is applied. Reference numeral 11 denotes the electronic equipment, and 12 denotes the main body of the electronic equipment. An electronic circuit, a CD / DVD player, and the like are incorporated in a metal casing to constitute the device main body 12 . Reference numeral 13 is a mounting bracket made of synthetic resin provided on the front of the machine body 12, and a CD / DVD insertion port (not shown in the figure) is provided on the mounting bracket. Symbol 14 is the front panel that can be opened and closed freely and is arranged on the front of the mounting bracket 13. When the switch button 17 is operated, the front panel will move from figure 1 The shown closed state turns the lower end as a fulcrum by about 90 degrees to become an open state. In this opened sta...

Abstract

The invention provides an electronic machine, which can utilize a waterproof part to prevent water from entering the inside of the machine through the periphery of an operation part capable of performing a press operation and a rotation operation. The electronic machine provided by the invention is provided with a front panel with an opening, an electronic substrate arranged on the inside of the front panel, a switch mounted on the electronic substrate and provided with an operation shaft capable of performing the press operation and the rotation operation, the operation part mounted on the operation shaft and comprising an annular knob and a button rotated integrally with the knob, and a waterproof close cover arranged between the operation part and the switch and made of rubber material, wherein the waterproof close cover is used for covering the opening of the front panel, is glidingly and freely embedded on an annular bulge wall which is arranged coaxially with the operation shaft and erected on the front panel, and meanwhile is integrally and rotationally fixed on the operation part with the knob.

Description

technical field [0001] The present invention relates to an electronic device, and more particularly, to an electronic device including a waterproof operating body capable of both pressing and rotating operations. Background technique [0002] Electronic devices such as audio devices such as radios, CD players, and DVD players, and navigation devices used outdoors or on ships must take waterproof measures to prevent water from entering the interior of the device from the operation buttons. As an example of such a waterproof structure, in the waterproof structure of the rotary operation knob described in the following patent document 1, such as Figure 9 As shown, the sealing ring 7 is in contact with the inner peripheral edge of the hole of the front face support 2B, and the waterproof sheet 8 is positioned in front of the sealing ring 7, and the outer peripheral end of the waterproof sheet 8 is over the position where the sealing ring 7 and the front face support 2B are in co...
