Embodiment Construction

[0014] See Figure 1 to Figure 3 . figure 1 It is a three-dimensional schematic diagram of the input device of an embodiment. figure 2 for figure 1 Schematic diagram of the decomposition. image 3 for figure 1 Schematic diagram of the cross-section. The input device 10 of this embodiment is suitable for, but not limited to, environments with varying pressure or temperature differences. Among them, the environment where the pressure difference or the temperature difference changes is, for example, an environment with a large altitude difference in a short time, such as in the cabin of a sailing aircraft or the cabin of a submarine diving in the sea. In addition, the input device 10 of this embodiment uses a keyboard as an example, but is not limited to this.

[0015] The input device 10 of this embodiment includes a board layer 100, a circuit layer 200, a key layer 300, a protective layer 400, and a liquid-tight space 500. The board layer 100 has a first through hole 110. The ...

Abstract

An input device in an environment where pressure changes. The input device comprises a plate layer, a circuit layer, a keypad layer, a protection layer, and a sealed and liquid-tight space. The keypad layer is attached to the plate layer. The sealed and liquid-tight space is formed between the plate layer and the keypad layer. The circuit layer is disposed in the sealed and liquid-tight space. Furthermore, the plate layer has a first hole, and the circuit layer has a second hole corresponding to the first hole. The protection layer is attached to the plate layer and corresponds to the sealed and liquid-tight space. The air permeable rate of the protection layer is between 10% and 50% so that the inside pressure and the outside pressure of the input device can reach an equilibrium.

Description

【Technical Field】 [0001] The present invention relates to an input device, in particular to an input device suitable for a pressure difference environment. 【Background technique】 [0002] Nowadays, computers are widely used by the general public, and the keyboard is one of the main input devices of the computer. However, the traditional keyboard is not dustproof and waterproof. Therefore, the keyboard is easy to accumulate dirt after long-term use. What's more, if the user accidentally spills liquid on the keyboard, it will easily cause damage to the keyboard. [0003] In order to solve the problem of waterproof and dustproof, the industry has designed a silicone or rubber keyboard with excellent waterproof and airtightness. However, in an environment where the pressure changes or the temperature difference changes, the keys of the aforementioned silicone keyboard or rubber keyboard are prone to body deformation due to the influence of the pressure difference or the temperature ...
