Problems solved by technology

However, the operation feel of the silicone rubber keyboard is worse than that of the chocolate keyboard, and there will be swelling in the environment above 50°C, and it cannot meet the salt spray requirements
[0004] In addition, due to the relatively harsh working environment, once the circuit board inside the reinforced keyboard is damp, it is difficult to find and deal with it in time. If the circuit board is burned due to a short circuit, it will not only cause losses, but also affect normal use.

Embodiment Construction

[0021] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , figure 2 A reinforced keyboard suitable for harsh environments is shown, comprising: a protective case (1) and a chocolate keyboard (2), the chocolate keyboard (2) is embedded in the front of the protective case (1), and the front of the chocolate keyboard (2) Covered with a keyboard protective film (3), the keyboard protective film (3) is provided with a keyboard film pressing frame (4) for fixing the keyboard protective film (3) on the front of the chocolate keyboard (2); the keyboard film pressing frame ( 4) There is a key relief groove matching the chocolate keyboard (2) on the top, which is used to compress the keyboard protective film (3) around the key. The relative positions of the keyboard membrane pressing frame (4) and the front of the chocolate keyboard (2) are provided with screw holes, and the keyboard membrane...

Abstract

The invention discloses a reinforced keyboard suitable for severe environments, which comprises a protective shell and a chocolate keyboard, the chocolate keyboard is embedded in the front surface ofthe protective shell, the front surface of the chocolate keyboard is covered with a keyboard protective film, and the keyboard protective film is provided with a keyboard film pressing frame for fixing the keyboard protective film on the front surface of the chocolate keyboard; An alarm and a key switch used for controlling the alarm are arranged on the side wall of the protection shell, a humidity-sensitive resistor is arranged in the protection shell, and the alarm, the key switch and the humidity-sensitive resistor are connected through a humidity alarm circuit. The keyboard can meet the anti-rain and anti-sand-dust requirements, can be used in a salt mist environment, and is effectively prevented from being corroded by salt mist. The keyboard film pressing frame is fixed on the chocolate keyboard through the fastening screws and is easy to disassemble and assemble, and the keyboard protection film is convenient to replace. The humidity inside the protective shell is monitored in real time through the hygristor, once the humidity is too high, the alarm gives an alarm in time, and the keyboard circuit board is prevented from being burnt due to short circuit caused by dampness.

Description

technical field [0001] The invention relates to the field of reinforced computers, in particular to a reinforced keyboard suitable for harsh environments. Background technique [0002] Portable ruggedized equipment must be suitable for environments such as anti-salt spray, anti-rain, anti-sand and dust, and high temperature and humidity. The weak point of this kind of equipment is the design of the keyboard, which is generally used in the industry as chocolate keyboards and silicone rubber keyboards. The chocolate keyboard has a good hand feel and has been widely used in reinforced products in recent years, but its key substrate is galvanized steel, which cannot meet the requirements of salt spray; its structure cannot directly meet the requirements of sand and dust. [0003] The silicone rubber keyboard keys are integrated silicone, used in conjunction with the keyboard circuit board, to prevent rain, sand and dust. However, the operation feel of the silicone rubber keybo...
