Invention Example

detailed description

In order to achieve the above purpose, so as to increase the extended ear plates at both ends of the keycap, the keycap cannot be taken out, and the keycap anti-keying function is realized, which reduces the return to the repair rate. If it is forcibly disassembled, it will break and be damaged and cannot be used, thereby improving the keyboard. The effect of service life will be described clearly and completely in the following with reference to the drawings in the embodiments of the present invention.

As shown in FIGS. 1 to 5, the present invention provides a key-tight keyboard.

Example 1

As shown in FIG. 1, in an embodiment of the present invention, a key-tight keyboard includes a key core middle plate 2 and a key cap 3, and the key caps 3 are arranged in an array and installed on the key core mid plate 2 .

Further, a face cover is installed on the key core middle plate 2 in cooperation with the key cap 3.

As shown in FIGS. 3 and 4, in order to prevent the keycap 3 from being taken out, so as to realize the keycap anti-keying function, the keycap 3 is provided with an overhanging ear plate 7 on each side, the overhanging ear plate 7 and the keycap 3 It is fixed in a vertical distribution, and the fixing method of the overhanging ear plate 7 and the key cap 3 is an integrated fixing. For product stability and size limitation, the ratio of the overhanging ear plate 7 to the keycap 3 is less than one-fifth and greater than one-tenth; the actual protruding sides of the keycap are usually between 1 mm and 3 mm between. The protruding structure can usually be set to a square bar shape, a semicircular convex shape, or a small rectangular shape or a square shape. Of course, it can be set to an ear shape.

Example 2

A key-tight keyboard, as shown in FIGS. 2 and 5, the embodiment of the present invention is further limited on the basis of Embodiment 1.

Further, the material of the key cap 3 is silicone, and the key core middle plate 2 at the lower end of the key cap 3 is provided with a key cap silicone particle 5, a cavity is opened at the bottom of the key cap silicone particle 5, and the side of the key cap silicone particle 5 The key core middle plate 2 is provided with a key cap parallel rod 6, and the key cap parallel rod 6 is provided with fixing rods at both ends. In order to increase the knocking feeling of the key cap 3, the key cap silicone particles 5 are respectively provided with keys installed on both sides帽剪脚4. Since most of the scissor-type keyboard is made to imitate the use of the notebook keyboard, the keystroke is short, about 2-2.5mm. However, it is clear that our design is a relatively long key-stroke design with a scissor-structured keyboard. The key stroke is about 2.5-3.5mm. The keycap scissor leg 4 is different from the ordinary keycap scissor leg, except for the elastic material that can be used. Commonly used elastic materials, for example: TPU is a thermoplastic elastomer, rubber, thermoplastic elastomer TPE, styrene-based block copolymer type thermoplastic elastomer, polyolefin-based thermoplastic elastomer (TPO), etc.

Further, a double-layer conductive film 1 is installed on the top of the key core middle plate 2, and the double-layer conductive film 1 is disposed at a quarter of the top of the key core middle plate 2 from right to left.

Example 3

A key-tight keyboard, as shown in FIGS. 1 to 5, the embodiment of the present invention is further limited on the basis of Embodiment 1 and Embodiment 2.

Further, in order to improve the recognition in a dark environment, an LED lamp is installed on the key core middle plate 2 at the lower end of the key cap 3, the LED lamp is in a ring shape, a control switch is provided on the LED lamp, and the lower edge of the key cap 3 cooperates The LED light is provided with transparent materials.

Of course, in the above solution, the material of the overhanging ear plate 7 is set to be a hard material or a hard plastic; or a soft material can also be used to prevent the keycap from being pulled out and lost, and can also avoid damage, even after being removed You can also install it again and continue to use it. The soft material here may be TPU is a thermoplastic elastomer, rubber, thermoplastic elastomer TPE, styrene-based block copolymer type thermoplastic elastomer, polyolefin-based thermoplastic elastomer (TPO), etc. The overhanging ear plate 7 is integrally provided with the key cap 3, and the overhanging ear plate 7 is made of hard plastic material or elastic material. Alternatively, the overhanging ear plate 7 and the keycap 3 are fixedly arranged separately, and the overhanging ear plate 7 is made of hard plastic material or elastic material. The hard plastic material here is a hard plastic commonly used in ordinary electronic products, and the elastic material here may use the soft material described in this paragraph.

It should be noted that the extended ear plates 7 are added at both ends of the key cap 3, so that after the upper shell is added, the key cap 3 cannot be taken out, thereby realizing the key cap anti-keying function. If it is forcibly removed, it will break and be damaged and cannot be used, thereby improving The life of the keyboard.
