Electronic device with waterproof keyboard

Abstract

An electronic device with a waterproof keyboard includes a casing, a touch-press circuit arranged in the casing, a waterproof keyboard arranged in the casing and corresponding to the top of the touch-press circuit, and a pressure cover. The waterproof keyboard includes a hard layer, an elastic cushion body, a waterproof ring and a plurality of keys, the top surface of the elastic cushion body cannot be combined with the bottom surface of the hard layer relative to the displacement of the hard layer, and the waterproof ring is connected to the bottom surface of the elastic cushion body. Used to abut against the shell and surround the touch circuit, the plurality of keys are connected to the elastic pad and expose the hard layer. The gland is used to bond to the housing and press against the hard layer. In the present invention, a hard layer is arranged on the elastic pad, so that the waterproof ring can be pressed against the inner wall of the casing more stably and tightly, so as to improve the waterproof effect of the waterproof keyboard.

Description

technical field [0001] The invention relates to an electronic device with a waterproof keyboard, in particular to an electronic device with a waterproof keyboard that utilizes a waterproof pad body to achieve a waterproof function. Background technique [0002] refer to figure 1 , is a traditional electronic device 1 with waterproof buttons, which includes a casing 11, a touch circuit 12 arranged in the casing 11, a waterproof keyboard 13 arranged in the casing 11 and corresponding to the top of the touch circuit 12, and A gland 14 combined on the waterproof keyboard 13, the waterproof keyboard 13 and the gland 14 are locked by screws, the waterproof keyboard 13 includes a rubber pad 131 and a plurality of buttons 132 arranged on the rubber pad 131, and the rubber pad A waterproof ring 133 is formed on the bottom surface of 131 . When the button 132 is pressed, the rubber pad 131 is partially deformed and presses the touch switch on the pressure circuit 12 everywhere. [0...

Problems solved by technology

[0004] However, the disadvantage of this structure is that since the rubber pad 131 is a flexible material, it is easier to bend and deform due to extrusion or other forces (for example, in the process of screw locking with screws, the rubber pad 131 is partially deformed due to the torsion of the screw. twisted to produce bending deformation), once the rubber pad 131 is bent and deformed, it is impossible to ensure that the gland 14 can be evenly pressed against the rubber pad 131, and then it may cause the waterproof ring 133 to partially contact with the shell 11 due to insufficient pressure. There is a gap between them, so that water or liquid can easily pass between the waterproof ring 133 and the shell 11, destroying the touch circuit 12, and after testing, the waterproof level that this structure can achieve is only about IPX4
