Description

Technical Field

[0001] This utility model relates to the field of keycap structure technology, specifically a keycap structure. Background Technology

[0002] As the core interactive component of a keyboard, the keycaps are printed with letters, numbers, symbols, or function markings on their surface, directly guiding users to complete input operations. When in use, the keycaps are connected to mechanical switches or membrane switches via the bottom cross-shaped hinge. When pressed, they trigger signal transmission, thereby transmitting text.

[0003] For example, the utility model patent disclosed in publication number CN218866956U, a plastic keycap structure, relates to the field of keycap technology. This utility model includes a keycap body, two snap-fit ​​plates rotatably disposed on the keycap body, and two limiting plates disposed on the keycap body. The two limiting plates are horizontally disposed on both sides of the snap-fit ​​plates. Two snap-fit ​​blocks are fixedly installed on the side walls of each snap-fit ​​plate near the limiting plate. The snap-fit ​​plates are snapped into the limiting plates through the snap-fit ​​blocks. Two support plates are disposed on the keycap body. One end of each support plate is fixedly connected to the keycap body, and the other end is fixedly connected to each limiting plate in a corresponding manner. The snap-fit ​​blocks and limiting plates can fix the snap-fit ​​plates on the keycap body for easy use. By releasing the restriction between the snap-fit ​​blocks and the limiting plates, the snap-fit ​​plates can rotate on the keycap body. The snap-fit ​​plates provide a good leverage point for pulling the keycap body upward. By holding the two snap-fit ​​plates by hand, the keycap body can be easily pulled out of the keyboard.

[0004] While the aforementioned keycaps are easy to remove from the keyboard, they suffer from insufficient noise reduction during use and lack sufficient personalization. Therefore, a new keycap structure is urgently needed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a keycap structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a keycap structure, comprising a keycap housing for support, and a protective sleeve fixedly disposed on the outer end face of the keycap housing.

[0007] A cross-shaped retaining plate is fixedly disposed on the inner end face of the keycap housing, and the cross-shaped retaining plate is used for support and limiting.

[0008] The docking pin is fixedly disposed on the inner end face of the cross plate, and a cross pin groove is provided at the center of the inner end face of the docking pin. A protective pad is provided at the center of the lower end face of the docking pin.

[0009] A reinforcing rib is fixedly disposed between the docking shaft and the cross plate, and the reinforcing rib is used to strengthen the support of the docking shaft and the cross plate.

[0010] Preferably, the top of the protective cover is provided with a positioning slot, and the upper surface of the protective cover is provided with anti-slip protrusions at equal intervals. Multiple sets of anti-slip protrusions can increase the contact friction between the user's fingers and the top of the keycap shell, thereby improving the anti-slip performance of the keycap shell during use.

[0011] Preferably, a limiting plate is provided at the center of the upper end face of the keycap shell. The limiting plate is fixedly engaged with the protective shell through the positioning slot. The limiting plate facilitates subsequent light transmission, allowing users to quickly and easily change the identification color of the font on the keycap.

[0012] Preferably, four sets of LED beads are equidistantly arranged on the inner end face of the keycap housing opposite the limiting transparent plate. The limiting transparent plate is made of transparent material, and the LED beads can produce different colors. Then, through the light transmittance of the limiting transparent plate, the color of the upper part of the limiting transparent plate is changed, thereby improving the functional versatility of the keycap housing during use.

[0013] Preferably, the lower end face of the keycap housing is provided with support guide rods near the four corners, and a rubber silencing pad is provided on the lower end face of the support guide rod. The rubber silencing pad is made of rubber. At the same time, the support guide rod can be supported on the bottom of the keyboard in advance by the rubber silencing pad to prevent the side wall of the keycap housing from contacting the keyboard and thus generating noise.

[0014] Preferably, the docking hinge protrudes from the bottom of the keycap housing, and the bottom plane of the support guide rod is lower than the bottom plane of the docking hinge. During use, the support guide rod is lower than the bottom of the docking hinge, which facilitates early positioning with the bottom support of the keyboard and prevents excessive contact between the docking hinge and the key switch. At the same time, the docking hinge protruding from the bottom of the keycap housing also provides sufficient support and guiding space for the keycap housing when it is connected to the key switch, preventing the keycap housing from contacting the keyboard shell when it moves down, thus affecting quietness.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a docking hinge, a support guide rod, a rubber noise-reducing pad, and a protective pad, provides sufficient guiding space for the keycap shell when it is in use. This prevents the keycap shell from directly contacting the keyboard shell, thereby reducing friction noise from the keycap shell's vertical movement and the keyboard. At the same time, when the keycap shell moves down to the key switch, the rubber noise-reducing pad provides elastic cushioning with the keyboard shell, and the protective pad provides secondary elastic cushioning to the outside of the key switch. This not only improves the protection of the docking hinge and the key switch but also reduces noise when the keycap shell moves down, thus improving the quietness of the keycap shell during use.

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.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a keycap structure, comprising a keycap housing 4 for support, and a protective sleeve 1 fixedly disposed on the outer end face of the keycap housing 4.

[0024] A cross-shaped retaining plate 8 is fixedly installed on the inner end face of the keycap housing 4. The cross-shaped retaining plate 8 is used for support and limiting.

[0025] The docking shaft 3 is fixedly installed on the inner end face of the cross plate 8, and a cross shaft groove 5 is provided at the center of the inner end face of the docking shaft 3. A protective pad 10 is provided at the center of the lower end face of the docking shaft 3.

[0026] The reinforcing rib 9 is fixedly installed between the docking hinge 3 and the cross-shaped hinge 8. The reinforcing rib 9 is used to strengthen the support between the docking hinge 3 and the cross-shaped hinge 8. The four sets of reinforcing ribs 9 can provide sufficient support and connection between the cross-shaped hinge 8 and the docking hinge 3, so that the keycap shell 4 has sufficient support and guiding foundation when it is not in contact with the keyboard shell.

[0027] The top of the protective cover 1 is provided with a positioning slot 2, and the upper surface of the protective cover 1 is provided with anti-slip protrusions 11 at equal intervals. Multiple sets of anti-slip protrusions 11 can increase the contact friction between the user's fingers and the top of the keycap shell 4, thereby improving the anti-slip performance of the keycap shell 4 during use.

[0028] A limiting plate 12 is provided at the center of the upper surface of the keycap housing 4. The limiting plate 12 is fixedly connected to the protective shell 1 through the positioning slot 2. The limiting plate 12 can facilitate the subsequent light transmission, making it convenient for users to quickly and easily change the identification color of the font on the keycap.

[0029] Four sets of LED beads 13 are equidistantly arranged on the inner end face of the keycap housing 4, opposite the limiting plate 12. The limiting plate 12 is made of transparent material, and the LED beads 13 can produce different colors. Then, through the light transmittance of the limiting plate 12, the color of the upper part of the limiting plate 12 is changed, thereby improving the functional versatility of the keycap housing 4 during use.

[0030] Supporting guide rods 6 are provided near the four corners of the lower end face of the keycap housing 4, and rubber silencing pads 7 are provided on the lower end face of the supporting guide rods 6. The rubber silencing pads 7 are made of rubber. At the same time, the supporting guide rods 6 can be supported on the bottom of the keyboard in advance by the rubber silencing pads 7 to prevent the side wall of the keycap housing 4 from contacting the keyboard and thus generating noise.

[0031] The docking hinge 3 protrudes from the bottom of the keycap housing 4, and the bottom plane of the support guide rod 6 is lower than the bottom plane of the docking hinge 3. When in use, the support guide rod 6 is lower than the bottom of the docking hinge 3, which makes it easier to pre-position with the bottom support of the keyboard and prevent the docking hinge 3 from making excessive contact with the key switch. At the same time, the docking hinge 3 protruding from the bottom of the keycap housing 4 also makes it easier to provide sufficient support and guiding space for the keycap housing 4 when it is connected to the key switch, preventing the keycap housing 4 from contacting the keyboard shell when it moves down and affecting the quietness.

[0032] Working principle: During use, the mating hinge 3 protruding from the bottom of the keycap housing 4 provides sufficient guiding space for the keycap housing 4, preventing direct contact between the keycap housing 4 and the keyboard housing, thereby reducing friction noise from the vertical movement of the keycap housing 4 and the keyboard. At the same time, when the keycap housing 4 moves down to the key switch, the rubber silencing pad 7 provides elastic cushioning with the keyboard housing, and the protective pad 10 provides secondary elastic cushioning to the outside of the key switch. This not only improves the protection of the mating hinge 3 and the key switch, but also reduces the noise when the keycap housing 4 moves down, thereby improving the quietness of the keycap housing 4 during use. Since the mating hinge 3 does not contact the keyboard housing, multiple sets of reinforcing ribs 9 can strengthen the support strength of the mating hinge 3 side and the cross-shaped clamping plate 8, improving the stability of the vertical movement of the keycap housing 4. In addition, the support guide rod 6 can support and limit the bottom of the mating hinge 3 and the keyboard housing, preventing the keycap housing 4 from moving down too far and causing damage to the key switch.

[0033] 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.
