Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This utility model provides a technical solution: a Velcro keycap, comprising:

[0026] The keycap base shell and the Velcro assembly located on the upper part of the keycap base shell are detachably connected to the keycap cover via the Velcro assembly.

[0027] The hook and loop assembly includes a hook and loop sheet 8 and a hook and loop hook 9. One side of the hook and loop sheet 8 is provided with a velvet surface 81, and one side of the hook and loop hook 9 is provided with a hook surface 91 that is bonded to the velvet surface 81. The side of the hook and loop sheet 8 opposite to the velvet surface 81 is provided with a first adhesive layer 82 that is bonded to the keycap base shell, and the side of the hook and loop hook 9 opposite to the hook surface 91 is provided with a second adhesive layer 92 that is bonded to the keycap cover.

[0028] The keycap cover includes a transparent inner liner 7 and a cover body 2. The transparent inner liner 7 is bonded to the inner cavity of the cover body 2. The outer side of the cover body 2 is opaque, while the upper surface of the cover body 2 is translucent. The transparent inner liner 7 is bonded to the cover body 2 using a one-shot injection molding process (the transparent material is PC or PMMA). The cover body 2 is wrapped with the transparent inner liner using a two-shot injection molding process. The outer side of the cover body 2 is opaque while the upper surface is translucent, creating a unique visual effect for backlit character display. This allows the keycap cover to clearly display the characters during use. At the same time, the opaque outer part prevents light scattering (the light-shielding material is plastic with added light-shielding agent), enhancing the clarity of the display.

[0029] The keycap cover also includes a detachable TPU cover 10. A TPU surface layer 12 is bonded to the finger groove on the upper surface of the TPU cover 10. An alternating transparent beam 11 is integrally formed on the inner top of the TPU cover 10.

[0030] In a further preferred embodiment, the TPU cover 10 increases the diversity of keycap covers. The TPU material has good wear resistance and anti-slip properties, which can improve the user experience. The TPU surface layer bonded in the finger groove on the upper surface further optimizes the feel. The alternating arrangement of the transparent beams 11 can achieve a specific light transmission effect while ensuring the structural strength of the cover. Furthermore, it can be replaced with a silicone cover or a stamped metal cover according to the user's usage habits, thereby increasing the diversity of keycap covers.

[0031] The keycap base includes a base 1 and an inner shell 3. The inner shell 3 is snapped into the inner cavity of the base 1. The base 1 is an opaque base, and the inner shell 3 is a light-transmitting shell.

[0032] In this embodiment, the base 1 is an opaque base, and the inner shell 3 is a light-transmitting shell, which allows light to pass through the inner shell 3. Combined with different keycap covers, it can achieve a variety of light transmission effects. In keyboard applications, it can precisely control the light transmission area and improve the visual effect of the keycaps.

[0033] The inner shell 3 has a connecting key core 4 fixedly connected to the top. The lower surface of the connecting key core 4 has a cross-shaped connecting mounting hole 5 for plugging into the key. The lower surface of the base 1 has a groove 6. The connecting key core 4 is used to securely connect with the key. The cross-shaped connecting mounting hole 5 is compatible with common key structures and is easy to install.

[0034] The upper end of the inner shell 3 is provided with a protruding frame 31 that penetrates the base 1. The top of the inner shell 3 is provided with a mounting groove 32 located in the inner cavity of the protruding frame 31. The Velcro velvet piece 8 and the Velcro hook piece 9 are both set in the mounting groove 32.

[0035] In a further preferred embodiment, the protruding frame 31 of the inner shell 3 penetrates the base 1, increasing the stability of the connection between the inner shell 3 and the base 1. At the same time, the mounting groove 32 provides a dedicated mounting position for the Velcro assembly, making the installation of the Velcro velour 8 and the Velcro hook 9 more standardized and ensuring the connection effect between the two. Since the Velcro assembly can be completely hidden inside the protruding frame 31, the keycaps are not too high, thus improving the effect during use.

[0036] The first adhesive layer 82 is bonded to the bottom of the mounting groove 32, and the second adhesive layer 92 is bonded to the lower surface of the transparent inner liner 7. The stacking thickness of the Velcro velvet piece 8 and the Velcro hook piece 9 is 1mm. The 1mm stacking thickness ensures the connection strength while minimizing the impact on the overall thickness of the keycap and maintaining the compact structure of the keycap. The Velcro components can be purchased and used directly, and have good wear resistance. At the same time, the specifications of the Velcro hook piece 9 and the Velcro velvet piece 8 are smaller than the top view cross section of the mounting groove 32, thereby ensuring the light transmission effect.

[0037] It is worth noting that any material that can be glued with double-sided tape can be made into a keycap cover, which greatly expands the design possibilities of keycap covers and meets users' personalized customization needs.

[0038] In use, the Velcro velour 8 is firmly attached to the bottom of the mounting groove 32 of the keycap base shell through the first adhesive layer 82, and the Velcro hook 9 is attached to the transparent inner liner 7 of the keycap cover through the second adhesive layer 92. By utilizing the interlocking properties between the velour surface 81 of the Velcro velour 8 and the hook surface 91 of the Velcro hook 9, the keycap cover and the keycap base shell can be detachably connected.

[0039] When you need to replace the keycap cover, simply press the keycap cover to gently separate the Velcro hook 9 from the Velcro velour 8, so that you can remove the old keycap cover and replace it with the new one. The operation is simple and convenient.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
