Key, keyboard, manufacturing method for keyboard and mobile phone with keyboard

Abstract

The invention provides a key with patterns. The key comprises a base material layer, two opposite surfaces of the base material layer are an appearance surface and a bottom surface respectively, the base material layer of the key is provided with at least one gap penetrating the thickness of the base material layer, and the gap forms the patterns, wherein the key also comprises an elastic body layer which is attached to the bottom surface of the base material layer, at least one of the patterns comprises a closed ring, and gaps for forming the closed ring are continuous. An isolated part isolated by the patterns with the closed ring on the key can be stably kept on the key without adding a connecting point according to the key with the patterns, and the sensitivity of the key is not influenced. The invention also provides a keyboard with the key, a manufacturing method for the keyboard and a mobile phone comprising the keyboard. The method of the invention is convenient to operate, can realize mechanized production, and reduces the cost.

Description

technical field [0001] The invention relates to a button with patterns. The present invention also relates to a keyboard including the above-mentioned keys, a manufacturing method thereof and a mobile phone with the above-mentioned keyboard. Background technique [0002] Such as Figure 1a and Figure 1b As shown, among them, Figure 1b yes Figure 1a An enlarged view of a key 21 on the keyboard 2 of the present invention, the keyboard in the prior art includes a plurality of keys 21 with a pattern formed on the base material layer usually by etching, and the pattern consists of penetrating through the thickness of the base material layer The slit 211 constitutes. For some patterns that include closed loops, such as the numerals "4", "9", "0", letters "A", "P", etc., isolated portions are formed inside the closed loop pattern that are isolated from the surrounding substrate layer Therefore, it is necessary to add connection points 20 so that the isolated parts in these c...

AI Technical Summary

Problems solved by technology

Although this structure does not need to add connection points through the adhesive effect of the thin film on the appearance surface of the keyboard 2 formed by the base material layer, it can also keep the rest of the base isolated on the key 21 in the pattern with a closed ring after etching. The part of the material layer will not come off due to the effect of external force or gravity, but because the elasticity and stretchability of the film covered on the keyboard 2 are very small, when the keyboard 2 is in use, the degree to which a single key 21 is pressed will be affected. The limitation of the surrounding film reduces the sensitivity of the key 21

Moreover, as the usage time increases, the elasticity of the film will further decrease and the deformation that occurs after the keys 21 are pressed together is difficult to recover, and it will loosely cover the keyboard 2, which will affect the appearance of the keyboard 2 and be easily damaged.

In addition, after these films are damaged, because the strength of the double-sided adhesive is not enough, the keys 21 cannot be strongly supported. Therefore, the formed isolated parts are still easy to fall off from the keys 21, which affects the use and performance of the keyboard 2.
