Description

Technical Field

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

[0002] The keycaps trigger the keyboard circuit by pressing the switch, converting the physical action into an electrical signal that is transmitted to the device. The characters (letters, numbers, symbols) on the keycaps are intuitive indicators for users to operate the keyboard, making it convenient for users to use quickly and easily.

[0003] For example, the utility model patent disclosed in publication number CN208400761U discloses a keycap with a simple structure, easy manufacturing, and low cost. This utility model includes a body, a light-blocking base layer on the top of the body, and a character cutout portion on the light-blocking base layer. The body is a monochrome PBT keycap body, and the character cutout portion directly displays the upper surface of the body. A transition layer is provided on the side of the body, connecting to the edge of the light-blocking base layer; the edge of the transition layer is irregular, making each keycap unique.

[0004] While the aforementioned keycaps facilitate character printing, their internal support stability is insufficient. Furthermore, the keycaps are a single piece, making it difficult to replace the top keycap plate according to needs and aesthetics, thus reducing their practicality. Therefore, there is an urgent need for a keycap with a support structure to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a keycap with a support 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 with a support structure, comprising a keycap shell for support, four sets of reinforcing ribs evenly arranged on the inner end face of the keycap shell, and a fixing sleeve fixedly arranged on the inner end face of the four sets of reinforcing ribs, wherein each of the four sets of reinforcing ribs has a weight-reducing groove.

[0007] A positioning slot is provided at the center of the upper end face of the reinforcing rib plate, and the positioning slot is used for positioning and damping limit.

[0008] A locking groove is provided at equal intervals at the upper opening of the keycap housing, and the locking groove is used for sealing and limiting.

[0009] A positioning device is provided, which is then sealed and fixedly fastened to the upper end face of the keycap housing via the locking groove.

[0010] Preferably, the positioning device includes a fixed bushing, a locking cover plate is fixedly provided at the center of the upper end face of the fixed bushing, and LED beads are provided at the four corners of the lower end face of the locking cover plate. Four sets of positioning shafts are equidistantly arranged on the lower end face of the locking cover plate, three sets of sealing rings are equidistantly arranged on the side end face of the locking cover plate, positioning plates are symmetrically arranged on the side end face of the locking cover plate, and a light-transmitting plate is embedded and fixed in the top of the locking cover plate.

[0011] Preferably, the locking cover plate is slidably engaged with the inside of the fixing sleeve through the fixing bushing, which can effectively improve the stability of the locking cover plate being positioned inside the keycap housing.

[0012] Preferably, the locking cover plate is slidably inserted into the positioning slot via the positioning shaft, which can improve the accuracy of the subsequent locking cover plate being connected to the upper part of the keycap housing, and also improve the stability of the damping locking between the positioning shaft and the positioning slot.

[0013] Preferably, the locking cover plate is fitted to the upper end face of the keycap housing by means of the sealing ring and the locking groove, thereby sealing and fixing it. The limiting engagement between the sealing ring and the locking groove can effectively improve the stability and convenience of subsequent docking between the locking cover plate and the upper part of the keycap housing.

[0014] Preferably, the positioning plate is fitted and connected to the side of the keycap housing. The positioning plate can quickly guide the installation of the locking cover and also facilitate the user to quickly disassemble and support the locking cover.

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

[0016] 1. This utility model, by setting a positioning device, effectively improves the stability of the connection between the locking cover plate and the upper part of the keycap housing when docking and installing the locking cover plate or the light-transmitting plate. The sealing ring and locking groove limit the connection, and the positioning shaft and positioning slot damping limit the connection. The four sets of reinforcing ribs inside the keycap housing can comprehensively improve the internal support stability of the keycap housing. At the same time, the detachable design of the locking cover plate and the keycap housing can effectively improve the convenience of subsequent use and maintenance of the equipment. It can also be matched with different light-transmitting plates according to needs, which also improves the adaptability of the equipment. Attached Figure Description

[0026] Positioning slot 6 is located at the center of the upper end face of the reinforcing rib plate 4. Positioning slot 6 is used for positioning and damping limit.

[0027] Locking grooves 7 are equidistantly arranged at the upper opening of the keycap housing 3. Locking grooves 7 are used for sealing and limiting.

[0028] Positioning device 2 is sealed and fixed to the upper end face of keycap housing 3 through locking groove 7.

[0029] like Figure 5 and Figure 6The positioning device 2 includes a fixed bushing 25, a locking cover plate 21 is fixedly installed at the center of the upper end face of the fixed bushing 25, and LED beads 23 are installed at the four corners of the lower end face of the locking cover plate 21. Four sets of positioning shafts 26 are equidistantly arranged on the lower end face of the locking cover plate 21. Three sets of sealing rings 22 are equidistantly arranged on the side end face of the locking cover plate 21. Positioning plates 24 are symmetrically arranged on the side end face of the locking cover plate 21. A light-transmitting plate 27 is embedded and fixed in the top of the locking cover plate 21.

[0030] like Figure 1 The locking cover 21 is slidably engaged with the inside of the fixing sleeve 1 through the fixing bushing 25, which can effectively improve the stability of the locking cover 21 in the keycap housing 3.

[0031] like Figure 6 The locking cover 21 is slidably inserted into the positioning slot 6 via the positioning shaft 26, which can improve the accuracy of the locking cover 21 being connected to the upper part of the keycap housing 3, and also improve the stability of the damping locking between the positioning shaft 26 and the positioning slot 6.

[0032] like Figure 2 The locking cover 21 is fitted to the locking groove 7 by the sealing ring 22 and then sealed and fixedly attached to the upper end face of the keycap housing 3. The limiting engagement between the sealing ring 22 and the locking groove 7 can effectively improve the stability and convenience of subsequent docking between the locking cover 21 and the upper part of the keycap housing 3.

[0033] like Figure 5 The positioning plate 24 is fitted and connected to the side of the keycap housing 3. The positioning plate 24 can quickly guide the installation of the locking cover 21 and also facilitate the user to quickly disassemble and support the locking cover 21.

[0034] Working principle: When docking and installing the locking cover plate 21 or the light-transmitting plate 27, the positioning of the four sets of positioning shafts 26 and the positioning slots 6 can improve the accuracy of positioning the locking cover plate 21 or the light-transmitting plate 27 to the upper part of the keycap housing 3. At the same time, the limiting structure of the sealing ring 22 and the locking groove 7 and the damping limiting of the positioning shaft 26 and the positioning slot 6 can effectively improve the stability of docking between the locking cover plate 21 and the upper part of the keycap housing 3. The detachable design of the locking cover plate 21 and the keycap housing 3 can effectively improve the convenience of subsequent use and maintenance of the equipment.
