Explanation of the invention (1) The present invention "key structure with double hardness and its manufacturing method" relates to a key structure with both rigid and soft materials and its manufacturing method; by this, a top surface layer is obtained It is hard, and the other is a soft and flexible key structure to provide a very good pressing feel and accurate and reliable transmission of pressing displacement. Buttons are widely used in our lives. They can be found in keyboards, digital phones or remote controls for appliances, and mobile phones. However, in the application of these keys, the key hardness can be roughly divided into two categories; one is hard, and the other is flexible and soft. Although hard keys can faithfully transmit displacement when pressed, they are also due to The keys are hard as a whole, and the touch feels rather stiff when they are pushed back. Although soft keys are softer and more flexible, they are often soft due to the softness. When the key is pressed, the pressure is not sure. Or the pressing pressure channel is offset by the deformation of the button itself, so that there is considerable room for improvement in operation accuracy. In the current technology, in response to the above-mentioned problem, there is a method such as the manufacturing method and structure of a key protection device No. 8 4 1 1 0 3 30 shown in the attachment, please refer to the fifth figure. A transparent plastic sheet (101) is adhered to the rubber key body (10), and a layer of black plastic ink (2) is printed on the back of the transparent plastic sheet. The glyph or pattern is printed with a layer of white plastic oil ink to form the expected key structure. The method of making it is as shown in the fourth figure. This type of keys can indeed obtain the structural characteristics of both the hard key surface and the flexible soft key body; however, because of its sticky substance,

Description of the invention (2) The materials are adhered to each other, and the plastic ink is still coated between the adhesive surfaces. The production process is complicated and the bonding strength is not satisfactory, so the actual implementation is not as expected. For this reason, the present inventor has a deep need for improvement in view of the above-mentioned conventional key structure, which is based on his experience in designing and manufacturing this type of product. The present invention is designed and modified, and the simpler design as far as possible in structure and manufacturing method is promoted, which can also have the advantages of simple manufacturing and reliable structure, and can achieve better use results. The main purpose of the present invention is to provide a key structure with both quality and softness; in order to obtain a key structure with an upper surface layer that is hard and other positions that are flexible and soft, to provide a very good pressing feel and reliability. The transfer presses the displacement action. The purpose of the second invention of the present invention is to provide a method for forming a key with both quality and softness; it is to make two kinds of original parts with different hardness (such as Rubber) and make higher hardness raw materials to be injection-molded first. Then, it is placed in another integral molding mold, and the elastic raw materials are injected into the mold, and the two are molded into one body, thereby obtaining a key structure with an upper surface layer that is hard and other elastic and soft. In order to further understand the individual purpose, technical means, characteristics, effects, etc. of the structure, characteristics, and manufacturing method of the present invention, a more detailed embodiment of the present invention is provided, and the accompanying drawings are described in detail as follows: The "key structure with double hardness and its manufacturing method" of the present invention is shown in the second figure of the manufacturing flow chart of the present invention, and the steps are as follows: Explanation (3) First, let the raw materials (such as Rubber Rubber) with a hardness of about 80 H s to 90 H s be injected into the mold to form the blank material of the hard surface layer (1 1); The hard surface layer (1 1) of the key body (1) is formed into the expected shape; 3. The hard surface layer (1 1) formed in advance is placed in another mold, and the hardness is about 40 H s. ~ 60 H s of raw material (rubber Rubber) to form the elastomer (1 2), which is combined with the hard surface layer (1) which is placed in the mold first; 4. The button body is to be removed from the mold (1) After printing, it is the table of the button body (1) (1 1) Print the number or text symbol on it to complete the expected key body (1) ° By the above-mentioned manufacturing method, since the key body (1) of the present invention is integrally formed from two different hardness raw materials, two The two are completely combined with each other, as shown in the third figure, and the upper layer has a structure with a hardness of 80 H s ~ 9 0 H s, while the lower layer has elasticity and a hardness of 4 0 H s ~ 6 0 H s ; When the user presses the button, the surface (1 1) part can accurately transmit its expected displacement action, while the lower layer elastomer (1 2) part can provide appropriate flexibility, making pressing easy. It is laborious and can quickly restore the normal key structure. 'Based on the above, the "key structure with double hardness and its manufacturing method" of the present invention has indeed achieved the expected effect, and can effectively solve the shortcomings of the habit. Furthermore, it is of great practical value; The same or similar inventions appear in domestic or foreign publications or public use, and they have already met the patents.
