[0002] In a mechanical keyboard, the fixing and installation methods of the keyboard often have a great influence on the feel and sound performance of the keyboard. Common structures of customized keyboards include tray (hull) structures, top cover installation structures, bottom installation structures, sandwich installation, washer (sheet) structures, etc. The core of the above structures is to improve the use experience by changing the way of fixing the shaft body and relying on the overall assembly of the upper and lower housings. When typing on the keyboards with the above structures, the entire housing will shake together with the shaft body. When the housing is relatively heavy, this phenomenon is not very obvious, but when the housing is light, the vibration feedback seriously affects the typing experience, the improvement of the feel during the knocking and using process is not obvious, the acoustic optimization is greater than the feel optimization, and the buffer stroke of the keyboard has certain limitations.

[0021] Embodiment 1

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a magnetic levitation keyboard buffer structure includes a base 1 and a keyboard inner liner 2, and the base 1 and the keyboard inner liner 2 are connected by a magnetic levitation buffer structure; the magnetic levitation buffer structure includes a magnetic levitation component 3 and a buffer limiting member 4; the magnetic levitation component 3 is arranged between the keyboard inner liner 2 and the base 1 below, and includes a first magnet 31 and a second magnet with the same magnetic poles facing each other, wherein the first magnet 31 is fixedly connected to the keyboard inner liner 2, and the second magnet is fixedly connected to the base 1 ( Figure 1 、 Figure 2 not shown in); the buffer limiting member 4 is arranged between the edge of the keyboard inner liner 2 and the base 1, and is divided into two major parts: a limiting component 41 and a buffer reset component 42; the keyboard inner liner 2 floats above the base 1 under the repulsive force between the first magnet 31 and the second magnet, and the function of the buffer limiting member 4 is to confine the keyboard inner liner 2 within the magnetic force range of the magnetic levitation component 3 and enable the keyboard inner liner 2 to automatically reset after being displaced by an external force;

[0023] Among them, the function of the limiting component 41 is to guide and limit the displacement of part of the keyboard inner liner 2 in the horizontal direction when the keyboard is subjected to an external force (such as hitting the keyboard), and conduct the force to the buffer reset component 42 to cause it to deform. After the external force is removed, under the action of the buffer reset component 42, the keyboard inner liner 2 can return to its original position;

[0024] In practical applications, the limiting component 41 is composed of a fixed seat 411, a connecting rod 412 and a contact member 413; the fixed seat 411 is fixedly connected to the base 1; one end of the connecting rod 412 is hinged to the fixed seat 411, and the other end contacts the edge of the keyboard inner liner 2 through the contact member 413; the buffer reset component 42 is arranged between the fixed seat 411 and the connecting rod 412.

[0025] To reduce the friction between the keyboard inner liner 2 and the base 1 during use, reduce wear, reduce losses and noises, a sealed bearing is selected as the contact member 413 that abuts against the edge of the keyboard inner liner 2, which can ensure the smoothness of pressing and rebounding during keyboard use.

[0026] In practical applications, a leaf spring is used as the buffer and reset component 42, which has a simple structure, occupies little space, and is convenient for disassembly, maintenance, and replacement.

[0027] To ensure the balance and stability of the structure, a set of buffer and limit components 4 are provided on each of the left and right sides of the keyboard inner housing 2. The number of each set is three, one of which is located on the side and two are located at the top corners, inclined 45° inward. In practical applications, longitudinal limit and installation components are also symmetrically arranged on the edge of the keyboard inner housing 2 to further limit the longitudinal movement space of the inner housing and also to prevent the keyboard inner housing 2 from disengaging from the installation position, ensuring the integrity of the overall keyboard structure.

[0028] Through the combined action of the magnetic levitation component 3 and the buffer and limit component 4, the inner housing can stably levitate above the keyboard base 1. There is no direct mechanical connection between the keyboard inner housing 2 and the outer shell, which can reduce mechanical friction and the noise when typing on the keyboard. Through the buffering and rebound of the magnetic levitation component 3, the typing feel of the keyboard is improved. The magnetic levitation design enables the keyboard installation structure to have sufficient buffer travel, and since the inner housing has become an independent whole relative to the base 1 in this structure, the sound feedback when typing on the keyboard is also significantly improved.

[0029] To ensure that the number of the magnetic levitation components 3 is at least two and is symmetrically distributed left and right to ensure the balance of both sides of the keyboard.

[0030] Embodiment 2

[0031] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a magnetic levitation keyboard buffer structure includes a base 1 and a keyboard inner housing 2, and the base 1 and the keyboard inner housing 2 are connected through a magnetic levitation buffer structure; the magnetic levitation buffer structure includes a magnetic levitation component 3 and a buffer and limit component 4; the magnetic levitation component 3 is arranged between the keyboard inner housing 2 and the base 1 below, and includes a first magnet 31 and a second magnet with the same magnetic poles facing each other. Among them, the first magnet 31 is fixedly connected to the keyboard inner housing 2, and the second magnet is fixedly connected to the base 1 ( Figure 1 、 Figure 2 not shown in); the buffer and limit component 4 is arranged between the edge of the keyboard inner housing 2 and the base 1, and is divided into two major parts: a limit component 41 and a buffer and reset component 42; the keyboard inner housing 2 levitates above the base 1 under the repulsive force between the first magnet 31 and the second magnet, and the role of the buffer and limit component 4 is to confine the keyboard inner housing 2 within the magnetic force range of the magnetic levitation component 3 and enable the keyboard inner housing 2 to automatically reset after being displaced by an external force;

[0032] The function of the limit component 41 is to guide and limit the displacement of the keyboard inner housing 2 in the horizontal direction when the keyboard is subjected to external forces (such as hitting the keyboard), and conduct the force to the buffer and reset component 42 to cause it to deform. After the external force is removed, under the action of the buffer and reset component 42, the keyboard inner housing 2 can return to its original position;

[0033] In practical applications, the limit component 41 is composed of a fixed seat 411, a connecting rod 412, and a contact member 413; the fixed seat 411 is fixedly connected to the base 1; one end of the connecting rod 412 is hinged to the fixed seat 411, and the other end contacts the edge of the keyboard inner housing 2 through the contact member 413; the buffer and reset component 42 is arranged between the fixed seat 411 and the connecting rod 412.

[0034] To reduce the friction between the keyboard inner housing 2 and the base 1 during use, reduce wear, reduce losses and noise, a sealed bearing is selected as the contact member 413 that abuts against the edge of the keyboard inner housing 2, which can ensure the smoothness of pressing and rebounding during keyboard use, and also extend the service life of the keyboard.

[0035] In practical applications, a leaf spring is used as the buffer and reset component 42, which has a simple structure, occupies a small space, and is convenient for disassembly, maintenance, and replacement.

[0036] To ensure the balance and stability of the structure, a set of buffer and limit components 4 are arranged on each of the left and right sides of the keyboard inner housing 2, with three in each group. One is located on the side, and two are located at the top corners, slanting inward at 45°; in practical applications, longitudinal limit mounting components are also symmetrically arranged on the edge of the keyboard inner housing 2 to further limit the longitudinal movement space of the inner housing, and also to prevent the keyboard inner housing 2 from slipping out of the installation position, ensuring the integrity of the overall keyboard structure;

[0037] Through the combined action of the magnetic levitation component 3 and the buffer and limit component 4, the inner housing can stably levitate above the keyboard base 1. There is no direct mechanical connection between the keyboard inner housing 2 and the outer shell, which can reduce mechanical friction and noise when hitting the keyboard. Through the buffering and rebounding of the magnetic levitation component 3, the keyboard hitting feel is improved. The magnetic levitation design enables the keyboard installation structure to have sufficient buffer travel, and it is not easy to produce a sense of fatigue after long-term use. And because the inner housing has become an independent whole relative to the base 1 under this structure, the sound feedback when hitting the keyboard is also significantly improved.

[0038] Chamfers 411-a are provided on both sides of the fixed seat 411, which is convenient for setting at the corresponding positions of the top corners of the keyboard inner housing 2. A deformation cavity 411-b is arranged inside, which provides sufficient space for the deformation of the leaf spring and is also convenient for users to replace leaf springs of different specifications by themselves to adjust the feel.

[0039] In practical applications, the three buffer limit members 4 on the same side of the keyboard are fixed by a fixing bracket to ensure the stability of the installation structure and the assembly accuracy. At the same time, it can also ensure that the buffer limit members 4 on both sides are evenly stressed during use.

[0040] To ensure that the number of magnetic levitation components 3 is at least two and they are symmetrically distributed left and right to ensure the balance on both sides of the keyboard; similarly, multiple groups of magnetic levitation components 3 can be set and arranged at equal intervals, and users can adjust the buffer stroke and feel of the keyboard by increasing or decreasing the number of magnetic levitation components 3.

[0041] Advantages of the implementation of the present utility model:

[0042] With the combined action of the magnetic levitation components and the buffer limit members, the inner container can be stably suspended above the keyboard base. There is no direct mechanical connection between the keyboard inner container and the outer shell, which can reduce mechanical friction and the noise generated when typing on the keyboard, and effectively extend the service life of the installation structure; the buffer effect and rebound of the magnetic levitation components improve the typing feel of the keyboard. The magnetic levitation design enables the keyboard installation structure to have a sufficient buffer stroke, and it is not easy to cause fatigue during long-term use. Moreover, since the inner container has become an independent whole relative to the base under this structure, the sound feedback when typing on the keyboard is also significantly improved.
