Description

Portable Keyboard {Portable Keyboard}

The present invention relates to a portable keyboard in which all components of the portable keyboard are formed of a soft material. Since all materials are soft, the keyboard can be folded during transport. Moreover, it is easily assembled and has a waterproof function with little effort, time and cost.

4 shows a conventional keyboard. The keyboard 10 has a rigid bottom plate 1a. The circuit board 2a is mounted on the rigid lower plate 1a. One end of the lower plate 1a is connected to the transmission line. A piece body 3a is formed on the circuit body 2a. A plurality of elastic bodies 31a are integrally formed on the piece body 3a with respect to the joint portion 21a on the circuit board 2a. Moreover, a rigid top cover 4a is also mounted. The plurality of through holes 41a are mounted on the top cover 4a at positions relative to the plurality of elastic bodies 31a so that the plurality of through holes 41a are mounted with the keys 5 in the through holes 41a so that the elastic bodies 31a are the keys 5a. Is accommodated in). Thus, when the user presses the key 5a, the elastic body 31a moves downward to resist and act on the junction on the circuit board 2a so that the signal is transmitted to the main frame by the transmission line.

However, in the conventional keyboard 10a, the lower board 1a, the circuit board 2a, the upper cover 4a and the keyboard 5a are made of a rigid material and cannot be folded. The entire keyboard thus occupies a volume and is inconvenient to carry. On the other hand, since the above components in the assembly are assembled by locking, the lower plate 1a and the upper cover 4a are combined. This is inconvenient in assembly. In particular, the manufacturing process is difficult when the key 5a is assembled. Thus, the assembly of the entire keyboard increases labor, time and cost. On the other hand, in the conventional keyboard 10a, the upper portion of the upper cover 4a has a gap around the key 5a. When water falls to the keyboard 10a by circumference, the circuit in the keyboard 10a is short-circuited and thus the entire keyboard is broken.

Therefore, the main object of the present invention is to provide a portable keyboard in which all components of the portable keyboard are formed of a soft material. The keyboard contains the following components. Flexible bottom plate is mounted. The flexible circuit thin film is arranged on the flexible bottom plate and one end thereof is connected to the transmission line. The flexible piece is installed on the flexible circuit thin film and has a plurality of elastic bodies, the elastic body being positioned relative to the junction of the flexible thin film. Moreover, a flexible top cover is integrally formed on the top cover with a plurality of key portions located above the flexible piece and protruding upwards. The position of the key portion corresponds to the position of the elastic body such that a flexible top cover is formed on top of the flexible piece and a number of elastic bodies of the flexible piece are accurately received in the key portion. Thus, a complete keyboard is formed when the periphery of the aforementioned components are combined by sticking. Since the aforementioned components are soft, the keyboard can be folded in transit. Moreover, it can be easily assembled with less labor, time and cost and has a waterproof function.

Another object of the present invention is to provide a method with high accuracy in keyboard assembly, in which the periphery of all components is assembled together. Assembled happily with less time, effort and money.

Another object of the present invention is to provide a high accuracy method in keyboard assembly, in which no gap is formed between the top plate and the bottom cover. The entire keyboard is tightly sealed.

Various objects and features of the present invention will be more readily understood by the following detailed description that is described in connection with the accompanying drawings.

1 and 2 show a portable keyboard. In the present invention, the components in the keyboard are formed of a soft material. The soft material is TPU (thermoplastic polyurethane film). According to the upward direction, the keyboard 10 is located on the flexible lower plate 1 in the form of an elongated strip, and is positioned on the flexible lower plate, and each wire 211 and 221 and a plurality of joints 212 and 222 are provided. The lower circuit thin film 21 and the upper circuit thin film 21 mounted thereon, and the insulating thin film 23 is mounted therebetween, and the through hole 231 is located in the insulating thin film at the position with respect to the bonding portions 212 and 222. And a flexible circuit thin film 2 having 22). The joints 212 and 222 on the two film sheets 21 and 22 are conductive through contact. One end of the flexible circuit thin film 2 is connected to a small circuit board 24, which is then also connected to the main frame via a transmission line.

On the other hand, the flexible piece 3 is arrange | positioned at the flexible circuit thin film 3 company. A plurality of elastic bodies 31 are formed integrally with the flexible piece 3. The elastic body 31 is positioned relative to the junctions 212, 333 of the flexible circuit thin film 2.

In the present invention, the flexible top cover 4 is also mounted. The flexible top cover 4 is arranged above the flexible piece 3. In this embodiment, the flexible top cover 4 is mounted to have upper and lower lamination films 41 and 43. Each of the upper and lower lamination films 41 and 43 is equipped with a plurality of coalesced key portions 44 protruding upwards such that a plurality of elastic bodies 31 on the flexible piece portion 3 are key portions 44. Can be accommodated within. Peripheral portions of the upper and lower laminate films 41, 43 extend to the combination portions 411, 431 to be combined with the flexible lower plate 1. In addition, a piece body 42 having a flat surface is mounted between the upper and lower lamination films. The size of the piece body 42 is smaller than the size of the upper and lower lamination films 41 and 43. Indications for key functions such as A, B, C, 1, 2, 3 ... are printed on the piece body 42. By punching, the piece body 42 is punched into the key portion 44 on the upper thin film 41 so that an indication of the key is in the key portion 44. Thus, the marking can also be seen from above the upper thin film 41. Of course, those skilled in the art may print this indication on the inner surface of the key portion 44 or on the inner surface of the key portion 44 of the upper lamella film 41 or the lower lamella 43. Alternatively, the printed mark may be printed directly on the elastic body 31. Thus, the printed marks do not fall off.

Referring again to FIG. 1, when assembling, the flexible lower plate 1, the flexible circuit thin film 2, the flexible piece 3, and the flexible upper cover 4 are arranged in the order of facing down. The periphery of these components is then firmly combined with high accuracy to assemble the keyboard. Assembly work is convenient. If a keyboard is desired to be used, simply press any key 44 on the flexible top cover 4 so that the elastic body 31 in the key 44 moves downward relative to the flexible circuit thin film 2. By pressing, the bonding portion 222 of the upper thin film 22 is brought into contact with the bonding portion 212 of the upper thin film 21 to have conductivity. According to Fig. 3, if the keyboard is desired to be carried, the keyboard can be folded into a substantially cylindrical shape since all the components of the keyboard are soft to save space. Therefore, it can be easily transported in a small space.

In the present invention, since all components of the keyboard are soft, the keyboard can be folded for convenient transportation. At the time of assembly, the periphery of the components is combined with high accuracy, so the present invention can be assembled with less labor, time and cost. Because of the high accuracy that acts to combine the periphery of the keyboard 10, no gap is present between the flexible bottom plate and the flexible top cover 4. The entire keyboard is firmly sealed and waterproof. Moreover, keyboards are designed for ergonomic needs.

Although the present invention has been described based on the preferred embodiments, it should be understood that the present invention is not limited thereto. Various modifications and variations are possible to those skilled in the art from the foregoing description. Such modifications therefore fall within the scope of the present invention within the spirit described in the appended claims.
