Description

Technical Field

[0001] The utility model relates to the technical field of keyboard structure and design, in particular to a keyboard with a soft-spring type sound-absorbing structure. Background Art

[0002] In modern society, keyboards are widely used in various computers and electronic devices as an important tool for human-computer interaction. Traditional keyboard designs, especially gasket keyboards, usually adopt an upper and lower shell structure, with the gasket gasket sandwiched between the upper and lower covers to achieve stability and shock absorption. However, this design not only increases the complexity and cost during production and assembly, but also seems relatively cumbersome in terms of disassembly and maintenance, which is not conducive to the user's DIY (Do It Yourself) modification needs.

[0003] Specifically, traditional gasket keyboards require precise alignment of the upper and lower shells and the use of screws or other fasteners to fix them in multiple locations, which not only increases the complexity of the production process, but also increases the manufacturing cost of the product. At the same time, for consumers, if they want to personalize the keyboard or simply clean and maintain it, they need professional tools and skills to remove and reinstall these fasteners, which undoubtedly increases the user's usage threshold.

[0004] In addition, the sound and vibration generated by traditional keyboards when typing are also a focus of users. Although the gasket can reduce noise and vibration to a certain extent, due to the limitations of the upper and lower shell structures, its shock absorption and silencing effects still need to be improved. Especially in occasions that require a quiet environment, such as libraries, offices, or when working late at night, the noise of the keyboard may become a factor that disturbs others.

[0005] Therefore, how to provide a keyboard with simple structure, convenient assembly, low cost and excellent shock absorption and noise reduction performance has become a technical problem to be solved by the present utility model. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a keyboard with a soft-elastic sound-absorbing structure in response to the defects existing in the above-mentioned prior art, so as to solve the problems proposed in the above-mentioned background technology that the traditional gasket keyboard has a complex structure, high assembly cost, inconvenient disassembly and assembly, and the sound-absorbing and shock-absorbing effect needs to be improved.

[0007] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0008] A keyboard with a soft-elastic sound-absorbing structure, comprising a lower shell, a PCB board, a key, a positioning plate, and a plurality of silicone soft-elastic particles arranged between the PCB board and the lower shell;

[0009] The key comprises a shaft body, a shaft seat and a key cap, the shaft body is connected to the PCB board through the shaft seat, and the key cap is installed above the shaft body;

[0010] The silicone soft elastic particle comprises an annular outer side surface, a ring-shaped notch is provided in the middle of the annular outer side surface of the silicone soft elastic particle, and the outer side surface of the PCB board is evenly distributed with a card slot 2 matching the ring-shaped notch; the silicone soft elastic particle is connected with the PCB board through the ring-shaped notch so that the PCB board is clamped on the lower shell through the silicone soft elastic particle, so as to limit the soft elastic movement of the PCB board in the left and right and front and back directions in the shell cavity through the soft elastic effect of the silicone particle;

[0011] The lower shell includes a shell cavity, in which a positioning plate is arranged above a PCB board, and avoidance holes matching the outer side surface of the key are evenly distributed on the PCB board, and the PCB board is sleeved on the outer side surface of the key through the avoidance holes.

[0012] As a further solution of the utility model, the fixed connection between the positioning plate and the lower shell positions the PCB board in the shell cavity through the silicone soft bullet particles, so as to limit the upper and lower soft elastic movement of the PCB board in the shell cavity through the soft elastic effect of the silicone soft bullet particles.

[0013] As a further solution of the utility model, the silicone soft elastic particles have deformability and are used to provide cushioning when the user presses the keyboard to achieve a soft elastic effect.

[0014] As a further solution of the present invention, the PCB board, the keys and the positioning plate are connected to form a keyboard module with an integrated structure.

[0015] As a further solution of the utility model, the keyboard module is detachably connected to the lower shell by means of a snap connection using soft silicone bullets.

[0016] As a further solution of the present invention, the keyboard module can be disassembled from the lower shell for DIY modification and maintenance.

[0017] As a further solution of the utility model, the positioning plate has a protruding connection portion facing the bottom of the shell cavity, the positioning plate is fixedly connected to the PCB board through the protruding connection portion, and the outer side of the key is fixedly connected to the positioning plate.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Abandoning the traditional upper shell design, the keyboard structure of the present application has achieved significant lightness. This lightness not only reduces the use of raw materials and reduces production costs, but also makes the entire keyboard more portable, providing great convenience for users at a time when mobile office is becoming increasingly popular.

[0020] 2. The "no upper shell required" design greatly improves the ease and efficiency of assembly. Traditional gasket keyboards require precise alignment and fastening of the upper and lower shells, but this technical solution makes the assembly process faster and smoother. This not only reduces the complexity and error rate in the production process, but also provides users with a more friendly DIY modification experience.

[0021] 3. The design without upper shell and the use of silicone soft bullets further enhance the shock absorption and noise reduction effect of the keyboard. Without the obstruction of the upper shell, the silicone soft bullets can more effectively absorb and disperse the impact force generated when typing, thereby reducing the resonance and noise between the keyboard and the desktop or other hard objects. This is especially important in occasions that require a quiet working environment.

[0022] 4. From an environmental protection perspective, the "no need for upper shell" design also reflects resource conservation and environmental protection, reduces the production and waste of upper shells, helps reduce environmental pollution and waste of resources, and is in line with the current social trend of sustainable development.

[0023] 5. The keyboard module and the lower shell are detachably connected. When users need to perform DIY modification or maintenance, they only need to simply release the connection between the silicone soft bullet and the card slot to easily disassemble and assemble the keyboard module from the lower shell. This design greatly meets the personalized needs of users and reduces the threshold for modification and maintenance.

All of these are based on technical means and principles well known to ordinary technicians in this field to enhance the waterproof ability of the product, and can also ensure the stability and durability of the keyboard in a humid or dusty environment, and further improve the user experience.

[0041] The fixed connection between the positioning plate 5 and the lower shell 1 positions the PCB board 4 in the shell cavity 10 through the silicone soft elastic particles 3, and is used to limit the up and down soft elastic movement of the PCB board 4 in the shell cavity 10 through the soft elastic effect of the silicone soft elastic particles 3.

[0049] Embodiment 1:

[0050] The present embodiment provides a keyboard with a soft-spring type sound-absorbing structure, which is intended to solve the complexity of the traditional gasket structure keyboard in terms of assembly, disassembly and maintenance, while improving its shock absorption and sound-absorbing performance.

[0051] Specifically, the keyboard includes a lower shell 1, a PCB board 4, a key 12, a positioning plate 5 and a plurality of silicone soft bullets 3. Among them, the key 12 is composed of a shaft body 7, a shaft seat 11 and a key cap 8. The shaft body 7 is firmly connected to the PCB board 4 through the shaft seat 11, and the key cap 8 is installed on the shaft body 7. The silicone soft bullet 3 has an annular notch 9, which cooperates with the card slot 2 on the outer side of the PCB board 4 to achieve a card connection. This connection method not only simplifies the assembly process, but also reduces the production cost.

[0052] During the implementation process, the PCB board 4, the key 12 and the positioning plate 5 are first connected to form an integrated keyboard module. This step greatly improves production efficiency and facilitates subsequent assembly and maintenance. Next, in the shell cavity 10 of the lower shell 1, the keyboard module is detachably connected to the lower shell 1 through the silicone soft bullet particles 3. Due to the soft elastic effect of the silicone soft bullet particles 3, the movement of the keyboard module in the shell cavity 10 is subject to certain restrictions, thereby enhancing the stability and service life of the keyboard.

[0053] Silicone soft bullet 3 uses silicone material within the ShoreA hardness range, and the hardness value range of silicone soft bullet 3 is roughly between ShoreA 30-50. This range ensures that the silicone has sufficient elasticity to provide good cushioning and shock absorption effects, while ensuring the connection stability and detachability of the keyboard module. Through this design, users can enjoy fast and smooth keyboard operation while also easily performing DIY modification and maintenance.

[0054] In addition, the silicone soft particles 3 can provide effective cushioning when the user presses the keyboard, achieving a soft spring effect. This not only improves the comfort of using the keyboard, but also reduces the noise and vibration to a certain extent. Especially in occasions where a quiet environment is required, such as in a library or when working late at night, the noise reduction performance of the keyboard is particularly important.

[0055] It is worth mentioning that since the keyboard module and the lower shell 1 are detachably connected, when the user needs to perform DIY modification or maintenance, he only needs to simply release the connection between the silicone soft bullet 3 and the card slot 2 to easily disassemble and assemble the keyboard module from the lower shell 1. This design greatly meets the personalized needs of users and reduces the threshold for modification and maintenance.

[0056] In summary, the keyboard with a soft-elastic noise-absorbing structure provided in this embodiment provides a keyboard solution with a simple structure, easy assembly, low cost and excellent performance by simplifying the assembly process, reducing production costs, improving shock-absorbing and noise-absorbing performance and meeting user DIY needs.

[0057] Embodiment 2:

[0058] The present embodiment provides a soft-spring type silencer keyboard with an innovative structure and a manufacturing method thereof. The structure abandons the traditional gasket upper and lower shells 1 and only requires a lower shell 1. Through the ingenious combination of the silicone soft spring particles 3 and the PCB board 4, the keyboard module is stably fixed and conveniently disassembled and assembled.

[0059] Specifically, the keyboard structure includes a lower shell 1, a PCB board 4, a key 12, a positioning plate 5, and a plurality of silicone soft bullets 3. Among them, the key 12 is composed of a shaft body 7, a shaft seat 11, and a key cap 8. The shaft body 7 is firmly connected to the PCB board 4, the shaft seat 11 plays a supporting and fixing role, and the key cap 8 is installed above the shaft body 7. The silicone soft bullet 3 is designed to be able to be stuck on the PCB board 4, which not only provides a stable fixing effect, but also allows the entire keyboard module to be easily installed in the lower shell 1.

[0060] During the assembly process, the PCB board 4, the shaft body 7, the positioning plate 5 and the keycap 8 are first pre-assembled into a complete keyboard module. This step greatly simplifies the subsequent installation process. Then, the keyboard module is clamped in the lower shell 1 through the silicone soft bullets 3, realizing a new structure without screws. The silicone soft bullets 3 not only limit the left and right and front and back movements of the PCB board 4 in the shell cavity 10, but also cooperate with the limit of the lower shell 1 through the hole below it, so as to firmly fix the entire keyboard module on the lower shell 1.

[0061] It is worth mentioning that the keyboard structure in this embodiment is extremely convenient when consumers need to disassemble and assemble the keyboard. Users only need to stand up the keyboard and pull down the entire module with force, and use the soft elastic deformation characteristics of the silicone soft elastic particles 3 to easily pull the entire keyboard module out of the lower shell 1. This design greatly meets the user's needs for keyboard modification and maintenance.

[0062] In addition, the keyboard structure of this embodiment also has excellent soft elastic and noise reduction performance. Since there is no additional limit structure under the keyboard module, the keyboard can produce natural deformation when pressed, providing a buffer force for the user, thereby effectively reducing fatigue. At the same time, the silicone soft bullet particles 3 serve as a separation layer between the keyboard module and the lower shell 1, effectively eliminating the resonant sound generated when tapping the keyboard, achieving the effect of shock absorption and noise reduction.

[0063] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0064] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
