Problems solved by technology

When the user presses the button, the hard bottom layer is in conflict with the metal shrapnel at the bottom of the button panel, and the touch is not good, and it is difficult for the light emitted from the bottom of the button panel to pass through the bottom layer formed with the button pattern, making the button The visual effect of the button pattern of this kind of button panel is also not ideal, and also causes the visual effect of the whole button panel to be not good simultaneously

Embodiment Construction

[0019] see figure 1 and figure 2 , a key panel structure 100 of an electronic device according to a preferred embodiment of the present invention. The key panel structure 100 includes at least a soft surface layer 10 , a hard layer 20 , an adhesive layer 30 , a light guide layer 40 and a soft bottom layer 50 .

[0020] The soft surface layer 10 is made of a transparent and elastic polymer material, such as rubber (Rubber), thermoplastic polyurethane (Thermoplastic Polyurethane, TPU) or a combination of the two materials or other similar materials. The soft surface layer 10 has a thin sheet structure and its thickness is between 0.1-0.2 mm, preferably 0.2 mm. The soft surface layer 10 serves as the surface layer of the key panel structure 100 , and a key outline 12 is formed on the surface thereof. The key outline 12 is protruded or concave on the soft surface layer 10 , which is formed by hot pressing the soft surface layer 10 with a mold. In this embodiment, the key outl...

Abstract

The invention provides a key panel structure of an electronic device, which comprises a soft surface layer, a hard layer, a back adhesive layer, a light guide layer and a soft bottom layer. The surface of the soft surface layer is provided with a key outline, key patterns are printed on the hard layer, a light guide outline is printed on the bottom face of the light guide layer, a holding portion is formed on the soft bottom layer, and the soft surface layer, the hard layer, the back adhesive layer, the light guide layer and the soft bottom layer are sequentially lapped while the key outline, the key patterns, the light guide outline and the holding portion are disposed correspondingly. The key panel has fine visual effect and key touching. The invention further provides a method for manufacturing the key panel structure.

Description

technical field [0001] The present invention relates to a key panel structure of an electronic device and a method for manufacturing the key panel structure. Background technique [0002] With the rapid development of information technology, electronic devices such as mobile phones have become indispensable tools in people's daily life. In order to be convenient for users to carry, electronic devices are developing in the direction of being light, thin, short and small. On the key panel of electronic devices, the development direction is not only toward thinness, but also pursues the refinement of its visual and tactile sensations. [0003] The traditional manufacturing method of the key panel is generally to provide a key board and several keys, the key board is provided with several key holes, and the several keys cooperate with the key holes to form the whole key board. Since the keys are embedded in the key holes, the keys are The panel has a bumpy feeling, and the aes...
