Waterproof keyboard
A waterproof keyboard, including a keypad and a plurality of keys passing through the keypad. The keypad includes a compressive waterproof layer, a plate structure, and a plurality of through-holes, the compressive waterproof layer covering the plate structure, and the through-hole passing through the compressive waterproof layer and the plate structure. Each of the keys passes through one of the through-holes, and the compressive waterproof layer and the plate structure are clamped by means of a slot that is formed on a lateral surface of the key, to enable the key to be sealed with the compressive waterproof layer to form a sealed layer, so as to achieve the waterproof effect.
1. A waterproof keyboard, comprising:
a keypad, comprising a compressive waterproof layer, a plate structure, and a plurality of through-holes, the compressive waterproof layer covering the plate structure, and the through-holes passing through the compressive waterproof layer and the plate structure;
a plurality of keys, passing through the through-hole, and each of the keys comprising:
a shell, an opening portion being formed on an upper surface of the shell, and a slot being formed on a lateral surface of the shell, wherein the shell passes through the compressive waterproof layer and the plate structure, and the compressive waterproof layer and the plate structure are clamped by the slot, to enable the shell to be sealed with the compressive waterproof layer; and
a trigger mechanism, passing through the opening portion of the shell, to receive an external force so as to move relative to the shell; and
a circuit board, located below the trigger mechanism, and to be triggered by movement of the trigger mechanism.
2. The waterproof keyboard according to claim 1 , wherein the cross sectional area of the shell gradually decreases from a lower flange of the slot to a lower surface of the shell.
3. The waterproof keyboard according to claim 1 , wherein the compressive waterproof layer is formed on an upper surface of the plate structure by means of spraying.
4. The waterproof keyboard according to claim 1 , wherein the compressive waterproof layer is made of an elastic material.
5. The waterproof keyboard according to claim 4 , wherein the elastic material is selected from at least one of a Polyurethane (PU) waterproof material, a PolyVinyl Chloride (PVC) waterproof material, and a silica waterproof material.
6. The waterproof keyboard according to claim 1 , wherein a positioning post is formed on a lower surface of the shell, a plurality of positioning holes is provided in the circuit board, and each of the positioning posts is inserted into one of the positioning holes in the circuit board for fixing.
