Description

Technical Field

[0001] The utility model relates to the field of computer peripherals, in particular to a visual key for a notebook keyboard. Background Art

[0002] Keyboard keys are generally provided with suggestive letter patterns for people's convenience. Different countries use different languages, so the suggestive letter patterns on keyboards are also different. Currently, there are two ways to make letter patterns on traditional keyboards. One is to spray directly on the keyboard, and the other is to engrave the pattern on the keycap by laser engraving. Then, a corresponding backlight module is set on the keyboard, so that the pattern is displayed on the keycap through the backlight. The keycap patterns made by these two methods are fixed and cannot be changed. However, in actual production, due to the relatively low demand for keyboards in some minority languages, there is often a problem of backlog of inventory during production. In addition, a laser engraving mold is required for each language, and the mold development cost is high. Utility Model Content

[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0017] Example 1

[0018] See also Figure 1 and Figure 2 The embodiment of the utility model includes: a visual key for a notebook keyboard, the visual key is installed on a keyboard substrate 5 and includes: a support frame 4, a key cap 3 and a patch-type light-emitting module 2, the upper surface of the top of the key cap 3 is a plane,

[0019] The top of the keycap 3 is provided with a wire hole 301 that passes through the upper and lower surfaces of the keycap, and the wire hole 301 is arranged in the middle position near the top side of the keycap 3. The inner side surface of the top of the keycap 3 is also provided with two horizontal avoidance grooves 303 and four vertical avoidance grooves 304 and two connecting blocks 302. The bottom of the support frame 4 is fixed on the key position installed on the keyboard substrate 5. The top of the support frame 4 is provided with a clamping structure matching the connecting block 302 and a protruding structure opposite to the horizontal avoidance groove 303 and the vertical avoidance groove 304. Through the cooperation of the clamping structure and the connecting block 302, the keycap 3 can be stably installed on the top of the support frame 4.

[0020] The patch-type light-emitting module 2 is fixed on the top upper surface of the keycap 3 by bonding, and the center line of the patch-type light-emitting module 2 coincides with the center line of the keycap 3. The power supply line of the patch-type light-emitting module 2 continuously passes through the wire hole 301 and the keyboard substrate 5 and is connected to the power supply mechanism arranged under the keyboard substrate 5.

[0021] The size of the patch-type light-emitting module 2 is smaller than the size of the top upper surface of the keycap 3. In actual implementation, the size of the top upper surface of the keycap 3 is generally 0.8 to 1 mm larger than the size of the patch-type light-emitting module 3. In this way, when the patch-type light-emitting module 2 is attached to the top upper surface of the keycap 3, there will be no part that exceeds the position of the keycap 3, which can prevent the circuit from being damaged and affecting the photoelectric effect. A transparent press protection structure 1 is also provided on the top of the patch-type light-emitting module 2. The transparent press protection structure 1 is a transparent adhesive layer sprayed with UV light-curing adhesive. The size of the transparent adhesive layer is the same as the size of the top upper surface of the keycap 3. In this way, the patch-type light-emitting module 2 can be wrapped to prevent the patch-type light-emitting module 2 from being damaged when the keycap 3 is pressed multiple times, thereby affecting the photoelectric effect.

[0022] Example 2

[0023] See also Figure 1 and Figure 2The embodiment of the utility model includes: a visual key for a notebook keyboard, the visual key is installed on a keyboard substrate 5 and includes: a support frame 4, a key cap 3 and a patch-type light-emitting module 2, the upper surface of the top of the key cap 3 is a plane,

[0024] The top of the keycap 3 is provided with a wire hole 301 that passes through the upper and lower surfaces of the keycap, and the wire hole 301 is arranged in the middle position near the top side of the keycap 3. The inner side surface of the top of the keycap 3 is also provided with two horizontal avoidance grooves 303 and four vertical avoidance grooves 304 and two connecting blocks 302. The bottom of the support frame 4 is fixed on the key position installed on the keyboard substrate 5. The top of the support frame 4 is provided with a clamping structure matching the connecting block 302 and a protruding structure opposite to the horizontal avoidance groove 303 and the vertical avoidance groove 304. Through the cooperation of the clamping structure and the connecting block 302, the keycap 3 can be stably installed on the top of the support frame 4.

[0025] The patch-type light-emitting module 2 is fixed on the top upper surface of the keycap 3 by bonding, and the center line of the patch-type light-emitting module 2 coincides with the center line of the keycap 3. The power supply line of the patch-type light-emitting module 2 continuously passes through the wire hole 301 and the keyboard substrate 5 and is connected to the power supply mechanism arranged under the keyboard substrate 5.

[0026] The size of the SMD light-emitting module 2 is smaller than the size of the top surface of the keycap 3. In practice, the size of the top surface of the keycap 3 is generally 0.8 to 1 mm larger than the size of the SMD light-emitting module 3. This way, when the SMD light-emitting module 2 is attached to the top surface of the keycap 3, no part of it will extend beyond the keycap 3, thus preventing damage to the circuit and affecting the photoelectric effect.

[0027] The top of the SMD light-emitting module 2 is also equipped with a transparent press-on protection structure 1. This transparent press-on protection structure 1 is a press cap made of transparent PET injection molding. The outer contour dimensions of the press cap are the same as the upper surface dimensions of the keycap top. A bezel is provided in the middle of the back of the press cap, and the dimensions of the bezel match the dimensions of the light-emitting module. During installation, the SMD light-emitting module 2 is adhered to the upper surface of the keycap top on one side, and the other side is entirely embedded in the bezel. The bezel is then adhered and fixed to the press cap via the bezel. This effectively prevents damage to the SMD light-emitting module 2 when the keycap 3 is pressed, which could affect the photoelectric effect.

[0028] Through the above-mentioned embodiments 1 and 2, the patch-type light-emitting module 2 is fixed on the top of the keycap 3 to replace the backlight module, and then a transparent UV light-curing adhesive layer or a transparent PET pressure cap is set above the patch-type light-emitting module 2 to protect the patch-type light-emitting module 2 from circuit damage without affecting the use effect of the patch-type light-emitting module 2. Through this structure, the light-emitting pattern of each patch-type light-emitting module 2 can be independently controlled as needed during actual use, so that the actual user can switch the prompt letter mode as needed during use to meet the needs of use in different languages, and even DIY patterns according to his own preferences. Such a keyboard can simultaneously meet the requirements of key recognition in different countries and languages. On the one hand, the number of laser engraving screen molds can be reduced during keyboard production, the development cost can be reduced, the amount of paint used during production can be reduced, and it is more environmentally friendly. On the other hand, the versatility of the keyboard is significantly improved, and the keyboard can be effectively prevented from being squeezed in inventory due to small languages.
