Description

Technical Field

[0001] The utility model relates to the technical field of keycaps, in particular to a thermosublimation color printing light-transmitting keycap. Background Technique

[0002] When a computer is in use, commands and shortcut keys usually need to be input through the keyboard to facilitate the control of the computer. The keycap is a component on the top of the keyboard, and numbers, letters, and symbols corresponding to it are set on its surface for easy identification by users.

[0003] In existing keycaps, characters or patterns are color-printed on the surface of the keycap. The thermosublimation technology is used to print the characters or patterns on the surface of the keycap. Under vacuum high-temperature heating through the thermosublimation process, the ink on the transfer paper is transferred to the surface of the keycap. The keycap uses PPT material, so it is easy for the surface of the keycap to adhere to colors or patterns. However, the PPT material is a semi-transparent material with poor light-shielding effect. The appearance of the keycap will be light-transmitting, and the characters cannot emit light alone, which is likely to cause light pollution. If light-shielding powder is added, although the light-transmitting of the keycap can be avoided, the material properties will be changed, resulting in the easy peeling off of the pattern after color printing. Moreover, during the use of the keycap, due to the relatively brittle nature of the PPT material itself, the shaft body is likely to crack when the keycap pin is inserted into the keyboard. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a thermosublimation color printing light-transmitting keycap to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A thermosublimation color printing light-transmitting keycap, including a keycap body, an exterior layer is fixed at the bottom of the keycap body, and an anti-fouling film is coated on the bottom and around the exterior layer, and a buffer layer is fixed inside the keycap body.

[0006] By adopting the above technical solution, the keycap body is made of PC material with good toughness and not easy to deform. Therefore, the phenomenon of pin breakage and deformation can be avoided. At the same time, with the setting of the buffer layer, on the one hand, it buffers the keycap body to further avoid the phenomenon of pin breakage, and on the other hand, it can avoid the keycap body from colliding with the keyboard housing and keyboard shaft to generate noise. And the keycap body is not light-transmitting, while the exterior layer is made of PPT material and is semi-transparent. With the character slot, only the character position of the keyboard can be light-transmitting, which is convenient for night identification and avoids the generation of light pollution. And the PPT material exterior layer is convenient for thermosublimation color printing of characters or patterns on the surface of the exterior layer, and the adhesion is stable so that the characters are not easy to fall off. At the same time, with the Teflon anti-fouling film covering the exterior layer after color printing, it has good self-lubricating, non-sticking and other characteristics. On the one hand, it protects the characters, reduces the wear of the characters and extends the service life. On the other hand, dirt such as sweat stains, oil stains, and dust is difficult to adhere to the keycap, and it is convenient to clean.

[0007] Further, the keycap body is made of PC material, and the exterior layer is made of PPT material.

[0008] By adopting the above technical solution, the keycap body is made of PC material with good toughness and not easily deformed, so the phenomenon of pin breakage and deformation can be avoided. And the exterior layer of PPT material facilitates thermal sublimation printing of characters or patterns onto the surface of the exterior layer, with stable adhesion and the characters not easily falling off.

[0009] Further, the buffer layer is made of transparent silica gel, and the bottom of the buffer layer is adapted to the inner wall of the keycap body.

[0010] By adopting the above technical solution, firstly, it buffers the keycap body to further avoid the phenomenon of pin breakage. Secondly, it can prevent the keycap body from colliding with the keyboard housing and the keyboard axis to generate noise, and the transparent silica gel does not affect light transmission.

[0011] Further, the anti-fouling film is a Teflon coating.

[0012] By adopting the above technical solution, the Teflon anti-fouling film has good self-lubricating and non-sticking properties. Firstly, it protects the characters, reduces wear on the characters, and extends the service life. Secondly, dirt such as sweat stains, oil stains, and dust is difficult to adhere to the keycap, and it is convenient to clean.

[0013] Further, ribs and pins are respectively fixed inside the keycap body, a slot is opened at the top of the pin, and a character slot is opened on one side of the bottom of the keycap body.

[0014] By adopting the above technical solution, when assembling the keycap, align the pin and the slot with the keyboard axis, and then slip the pin and the slot over the top of the keyboard axis to complete the assembly work. And the ribs increase the connection stability between the pin and the keycap body, and the character slot facilitates the user to identify the corresponding function of the keycap.

[0015] Further, there are four ribs, and the four ribs are distributed in a circular array.

[0016] By adopting the above technical solution, the ribs increase the connection stability between the pin and the keycap body, and increasing the number of ribs can further enhance the stability.

[0017] Further, the slot is in a "cross" shape.

[0018] By adopting the above technical solution, the cross-shaped slot can be adapted to the key axes of most mechanical keyboards on the market, with wide applications and convenient for sales.

[0019] Further, a resistance-increasing sleeve is arranged inside the slot, and the resistance-increasing sleeve is made of silica gel.

[0020] By adopting the above technical solution, the friction between the keyboard axis and the slot is increased through the resistance-increasing sleeve, thereby reducing the occurrence of the phenomenon that the keycap drops off.

[0029] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0030] Example 1:

[0031] A thermosublimation color printing light-transmitting keycap, as Figures 1-4 shown, includes a keycap body 1. The keycap body 1 is made of PC material, which has good toughness and is not easily deformed. Therefore, the phenomenon of the pin 5 breaking and deforming can be avoided; an exterior layer 2 is fixed to the bottom of the keycap body 1. The exterior layer 2 is made of PPT material, and the material is semi-transparent. In combination with the character groove 3, only the character position of the keyboard can be light-transmitting, which is convenient for night recognition and avoids the generation of light pollution. Moreover, the PPT material exterior layer 2 is convenient for thermosublimation color printing characters or patterns onto the surface of the exterior layer 2, and the adhesion is stable so that the characters are not easily peeled off; an anti-fouling film 7 is coated on the bottom and around the exterior layer 2. The anti-fouling film 7 is a Teflon coating, which has good self-lubricating, non-sticking and other characteristics. One is to protect the characters, reduce the wear of the characters and extend the service life. The other is that dirt such as sweat stains, oil stains, and dust is difficult to adhere to the keycap and is convenient to clean; a buffer layer 8 is fixed inside the keycap body 1. The buffer layer 8 is made of transparent silicone. The bottom of the buffer layer 8 is adapted to the inner wall of the keycap body 1. One is to buffer the keycap body 1 to further avoid the phenomenon of the pin 5 breaking, and the other is to avoid the generation of noise when the keycap body 1 collides with the keyboard housing and the keyboard axis.

[0032] Refer to Figures 2-4 , in the above embodiment, ribs 4 and pins 5 are respectively fixed inside the keycap body 1. There are four ribs 4, and the four ribs 4 are distributed in an annular array. The stability of the connection between the pin 5 and the keycap body 1 is increased through the ribs 4; a slot 6 is opened at the top of the pin 5. The slot 6 is in a "cross" shape, which is convenient for connecting with the keyboard axis; a character groove 3 is opened on one side of the bottom of the keycap body 1, which is convenient for the user to identify the function corresponding to the keycap.

[0033] Example 2:

[0034] On the basis of the above Example 1, in order to increase the stability of the connection between the keycap and the keyboard axis, the following settings are now made.

[0035] Refer to Figures 1-4 , in the above embodiment, a resistance-increasing sleeve 9 is arranged inside the slot 6. The resistance-increasing sleeve 9 is made of silicone. The friction between the keyboard axis and the slot 6 is increased through the resistance-increasing sleeve 9, thereby reducing the phenomenon of the keycap falling off.

[0036] The implementation principle of the utility model is as follows: first, the keycap body 1, the character groove 3, the rib 4, the pin 5 and the slot 6 are processed and formed by injection molding, and then the keycap body 1 is placed in another injection molding machine to process the outer layer 2 by secondary injection molding, and the outer layer 2 is fixed to the keycap body 1, and then the buffer layer 8 and the resistance increasing sleeve 9 are processed and formed by secondary injection molding again, and then the thermal sublimation technology is used to print additional characters or patterns on the surface of the outer layer 2, and then the Teflon coating is coated on the surface of the outer layer 2 to form an anti-fouling film 7, thereby completing the processing of the keycap;

[0037] When assembling the keycap, align the pin 5 and the slot 6 with the keyboard shaft, and then put the pin 5 and the slot 6 on the top of the keyboard shaft to complete the assembly work. At the same time, the friction between the keyboard shaft and the slot 6 is increased by the resistance increasing sleeve 9, thereby reducing the phenomenon of the keycap falling off, and the rib 4 increases the stability of the connection between the pin 5 and the keycap body 1;

[0038] When the keycaps are in use, the keycap body 1 is made of PC material, which has good toughness and is not easy to deform, so the pin 5 can be prevented from breaking and deforming. At the same time, with the setting of the buffer layer 8, the keycap body 1 is buffered to further prevent the pin 5 from breaking. Secondly, it can prevent the keycap body 1 from colliding with the keyboard shell and the keyboard axis to produce noise. The keycap body 1 is opaque, and the outer layer 2 is semi-transparent made of PPT material. With the character groove 3, only the character position of the keyboard can be translucent, which is convenient for night recognition and avoids light pollution. The outer layer 2 made of PPT material is convenient for thermal sublimation color printing of characters or patterns to the surface of the outer layer 2, and the adhesion is stable so that the characters are not easy to fall off. At the same time, with the Teflon anti-fouling film 7, it has good self-lubrication, non-stick and other characteristics. First, it protects the characters, reduces the wear of the characters and prolongs the service life. Second, sweat stains, oil stains, dust and other dirt are difficult to adhere to the keycaps and are easy to clean.
