DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides: a primer-free laptop backlight keycap, such as Figure 1-Figure 5As shown, it includes a keycap shell 1 for limiting the light-transmitting rubber cap top cover 12 and a light-transmitting rubber cap top cover 12 for protecting the keycap shell 1 and being snap-fitted with the keycap shell 1; an inner groove 2 is provided on the top surface of the keycap shell 1, a bottom groove 5 is provided on the bottom surface of the keycap shell 1, and a light-transmitting plate 4 is installed through the center of the keycap shell 1; a bracket 8 is snap-fitted inside the bottom groove 5, and an air cushion 11 is provided at the center of the bracket 8.

[0031] Preferably, the inner groove 2 and the bottom groove 5 are opened to the same depth, and a plurality of groups of slots 3 are opened at equal intervals on the inner wall of the inner groove 2. The keycap shell 1 itself is made of PVE structural material and is not light-transmitting. The inner groove 2 opened on the upper surface of the keycap shell 1 and the bottom groove 5 opened on the lower surface of the keycap shell 1 are both integrally die-cast. Since the die-casting depths of the inner groove 2 and the bottom groove 5 are the same as a whole, the keycap shell 1 as a whole does not need to be divided into the front and back sides during later processing and production, making the processing more convenient. During later processing, the inner groove 2 is positioned on one side where the slot 3 is opened, and the bottom groove 5 is positioned on one side where the clamping column 6 and the bracket 7 are installed. The opened slot 3 is ensured to cooperate with the positioning block 15, so that the keycap shell 1 and the light-transmitting rubber cap top cover 12 are connected. The clamping column 6 and the bracket 7 limit the bracket 8, so that the keycap shell 1 as a whole can be bounced up, ensuring that the keycap shell 1 and the light-transmitting rubber cap top cover 12 can be used stably after cooperation.

[0032] The depths of the inner groove 2 and the bottom groove 5 are consistent, which means that the upper and lower surfaces of the keycap shell are symmetrical in structure. This design makes it unnecessary to distinguish the front and back sides of the keycap shell during the manufacturing process, simplifying the manufacturing process. The inner wall of the inner groove 2 is opened at equal distances for connecting with the light-transmitting rubber cap top cover 12. This design allows a stable connection between the keycap shell 1 and the light-transmitting rubber cap top cover 12.

[0033] The inner tank 2 and the bottom tank 5 are both manufactured by integral die-casting, and this process can ensure the structural strength and dimensional accuracy of the product.

[0034] Since the key cap housing 1 has a symmetrical structure, there is no need to distinguish between the upper and lower parts during processing, which can improve production efficiency and reduce error rates.

[0035] The arrangement of the card slot 3 ensures the cooperation with the positioning card block 15 , thereby ensuring the accurate connection between the key cap housing 1 and the light-transmitting rubber cap top cover 12 .

[0036] The clamping column 6 and the bracket 7 limit the bracket 8, ensuring that the keycap housing 1 can be used stably after assembly without loosening or displacement.

[0037] Due to the design of the clamping column 6 and the bracket 7, the key cap housing 1 can be bounced as a whole, which can provide better touch and feedback during use and enhance the user experience.

[0038] The stable connection between the key cap housing 1 and the light-transmitting rubber cap top cover 12 ensures the long-term stable use of the keyboard and reduces the frequency of maintenance and replacement.

[0039] In summary, the design of this keycap shell has obvious advantages in structure, manufacturing and use, which can improve production efficiency, ensure product quality and provide a good user experience.

[0040] Furthermore, the light-transmitting plate 4 is an acrylic plate, and the upper and lower sides of the light-transmitting plate 4 are respectively parallel to the inner surface of the keycap shell 1. The main body of the light-transmitting plate 4 is an acrylic plate to ensure its high transmittance, so that the light on the keyboard mold can be efficiently transmitted to illuminate the light-transmitting rubber cap top cover 12. Since the light-transmitting plate 4 is embedded and installed in the center of the keycap shell 1, and the upper and lower surfaces are consistent with the keycap shell 1, the light-transmitting plate 4 will not affect the use of the bracket 8 and the air cushion 11.

[0041] Furthermore, two groups of clamping columns 6 are symmetrically installed on one side of the bottom groove 5, and two groups of brackets 7 are symmetrically installed on the other side of the bottom groove 5. The distance between the two groups of brackets 7 is greater than the distance between the two groups of clamping columns 6. The clamping columns 6 installed in the bottom groove 5 are engaged with the two groups of support rods 9 on one side of the bracket 8, so that one end of the bracket 8 can be fixed, and the bracket 7 installed on the other side of the bottom groove 5 can assist in limiting one end of the bracket 8, ensuring that the bracket 8 can elastically support the keycap shell 1.

[0042] It is worth mentioning that two groups of support rods 9 are respectively installed at both ends of the bracket 8. The two groups of support rods 9 on one side of the bracket 8 are clamped and installed with the clamping column 6, and the two groups of support rods 9 on the other side of the bracket 8 are movably fitted inside the bracket 7. The support rods 9 installed at both ends of the bracket 8 cooperate with the clamping column 6 and the bracket 7 respectively, so that the bracket 8 can support the keycap shell 1, so that the keycap shell 1 as a whole can bounce up stably to ensure the pressing touch of the keycap, meet the pressing touch of the notebook keyboard during use, and make the keycap pressing more comfortable.

[0043] Specifically, a through hole 10 is opened in the center of the bracket 8, and the diameter of the through hole 10 is larger than the diameter of the air cushion 11. The air cushion 11 is movably extended from the inside of the through hole 10 into the fitting bottom groove 5 for movably installation. The through hole 10 opened in the center of the bracket 8 enables the air cushion 11 to extend out and fit the bottom of the keycap shell 1, so that the bracket 8 can cooperate with the air cushion 11 to lift the keycap shell 1 to meet the pressing requirements, and can clearly define the typing feel to ensure that there will be no accidental touches, continuous typing, or word jamming during the use of the keycaps.

[0044] The light-transmitting plate 4 is made of an acrylic plate, which is known for its high transparency and is very suitable for components that require light to pass through. The light-transmitting plate 4 is parallel to the inner surface of the keycap housing 1 and is embedded in the center of the keycap housing 1. This design ensures the light-transmitting effect without affecting the functions of the bracket 8 and the air cushion 11.

[0045] The clamping column 6 inside the bottom groove 5 is engaged with the support rod 9 of the bracket 8 to ensure that one end of the bracket 8 can be fixed, and the bracket 7 assists in limiting the other end of the bracket 8. This design enables the bracket 8 to elastically support the keycap shell 1.

[0046] The support rods 9 at both ends of the bracket 8 cooperate with the clamping column 6 and the bracket 7 respectively, ensuring the overall stability of the keycap housing 1 and providing appropriate elasticity when pressed, thereby improving the tactile feeling during use.

[0047] The through hole 10 opened in the center of the bracket 8 allows the air cushion 11 to extend out and fit the bottom of the keycap shell 1. This design allows the air cushion 11 to provide additional cushioning when the keycap shell 1 is pressed, making the pressing of the keycap more comfortable.

[0048] The cooperation between the air cushion 11 and the bracket 8 ensures that the keycap will not have problems such as accidental touch, continuous typing or word jamming during use, thereby improving the typing accuracy and the overall user experience.

[0049] In summary, these design details not only ensure the light transmittance and aesthetics of the keyboard, but also improve the stability and comfort of the keyboard through fine structural design. Through the cooperation of the bracket and the air cushion, this keycap shell design can provide a more precise and comfortable typing experience, especially on laptop keyboards that require frequent keystrokes. These designs take into account durability, touch and user interaction, thereby improving the performance of the keyboard and user satisfaction as a whole.

[0050] In addition, the light-transmitting rubber cap top cover 12 is a polycarbonate structure, and a connecting card plate 13 is fixedly installed at the bottom of the light-transmitting rubber cap top cover 12. The light-transmitting rubber cap top cover 12 is a polycarbonate structure, so that the light-transmitting rubber cap top cover 12 maintains a high transparency state, and at the same time reduces the state of oiling during long-term use. The connecting card plate 13 at the bottom of the light-transmitting rubber cap top cover 12 can be completely inserted into the inner groove 2 to limit the light-transmitting rubber cap top cover 12, so as to ensure that the light-transmitting rubber cap top cover 12 will not be separated from the keycap shell 1 during the use of the keyboard. When the light-transmitting rubber cap top cover 12 needs to be removed and replaced, the light-transmitting rubber cap top cover 12 needs to be lifted up by a removal tool; the light-transmitting rubber cap top cover 12 is made of transparent polycarbonate (PC) material. The polycarbonate material has good transparency, which can make the internal structure clear at a glance, and also has a certain hardness and toughness, which is suitable as a material for keyboard components. The polycarbonate material may have a certain degree of self-lubrication, which means that when the light-transmitting rubber cap top cover 12 rubs against other parts, it can reduce the direct friction between metal or plastic, thereby reducing wear and extending the service life. Due to the self-lubricating property, this design may reduce the friction sound during key operation, making the keyboard quieter. At the same time, good rebound characteristics and reduced friction also help to improve the user's typing experience. The self-lubricating property reduces friction and wear, which may significantly extend the service life of the keyboard, especially in the case of high-frequency use. The traditional light-transmitting rubber cap top cover 12 generally uses POM plus glass fiber or PA plus glass fiber, and the material is difficult to mold and opaque. The self-lubricating PCR PC material developed by itself is used, with a density of 1.21. The low density can achieve plastic reduction and weight reduction; the color is transparent and saves power consumption; during molding, the mold can be shared, the defective rate is low, and molding is easy; no odor is beneficial to occupational health; easy to recycle, convenient for overall material recycling; good toughness, convenient disassembly; excellent rigidity, good structural support; ESG is easy, and PCR is easy to achieve.

[0051] Preferably, the height of the connecting card plate 13 is consistent with the depth of the inner groove 2, and the outer surface of the connecting card plate 13 is plugged in and installed against the inner wall of the light-transmitting plate 4. The connecting card plate 13 can be completely inserted into the inner groove 2, and the outer surface of the connecting card plate 13 can stably fit the inner wall of the light-transmitting plate 4, thereby improving the connectivity between the light-transmitting rubber cap top cover 12 and the keycap shell 1.

[0052] It is worth mentioning that two groups of deformation grooves 14 are respectively opened on the two sides of the connecting card plate 13 corresponding to each group of card slots 3, and a group of positioning blocks 15 are fixedly installed on the outside of the connecting card plate 13 between each two groups of deformation grooves 14. The deformation grooves 14 opened on each side of the connecting card plate 13 enable the connecting card plate 13 between the two groups of deformation grooves 14 to have the ability to deform, so that after the connecting card plate 13 is inserted into the inner groove 2, the position where the positioning block 15 is installed can shrink inward until the positioning block 15 is inserted into the card slot 3 and then restored, thereby ensuring the stability of the use of the positioning block 15 and the stability of the connection with the card slot 3.

[0053] Specifically, the positioning block 15 is elastically inserted into the slot 3, and the lower surface of the light-transmitting rubber cap top cover 12 fits the top surface of the keycap shell 1. After the positioning block 15 is inserted into the slot 3, the light-transmitting rubber cap top cover 12 fits the top surface of the keycap shell 1, reducing the entry of dust between the keycap shell 1 and the light-transmitting rubber cap top cover 12, and avoiding the light-transmitting plate 4 or the light-transmitting rubber cap top cover 12 being covered by the entry of dust during use, resulting in problems in the use of the keycap.

[0054] The design of the deformation groove 14 enables the connecting card 13 to have a certain deformation ability when inserted into the inner groove 2. This design allows the connecting card 13 to adapt to the shape of the keycap housing 1 during installation, ensuring that the connecting card 13 can be smoothly inserted into the inner groove 2.

[0055] The positioning block 15 fixedly installed between each group of deformation grooves 14 can be elastically inserted into the slot 3 after the connecting card plate 13 is inserted into the inner slot 2. This design ensures the stability of the connection and allows the positioning block 15 to be firmly positioned in the inner slot 2.

[0056] The lower surface of the light-transmitting rubber cap top cover 12 is fitted with the top surface of the keycap shell 1. This design reduces the possibility of dust entering between the keycap shell 1 and the light-transmitting rubber cap top cover 12, thereby protecting the light-transmitting plate 4 and the light-transmitting rubber cap top cover 12 from dust.

[0057] The tight fit of the light-transmitting rubber cap top cover 12 ensures the stability of the keycap during use, avoids keycap use problems caused by the entry of dust or other foreign matter, and improves the overall durability of the keyboard.

[0058] These design details further emphasize the durability, stability and user experience of the keyboard structure. Through the design of the deformation groove 14 and the positioning card block 15, the connecting card plate 13 can be flexibly combined with the keycap shell 1 while maintaining a stable connection. The installation method of the transparent rubber cap top cover 12 not only improves the appearance integrity of the keyboard, but also reduces maintenance requirements and ensures long-term reliability. These designs take into account mechanical strength, dust protection and comfort, thereby improving the overall performance of the keyboard.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
