Technical Field

[0001] This utility model relates to the field of keyboard device technology, and in particular discloses a keyboard device with an arc-shaped arrangement of keyboard keys. Background Technology

[0002] With the development of computer technology, the keyboard, as an important input device for computers, has become an indispensable part of people's daily work and life. Traditional keyboard devices usually adopt a flat layout design, with the keys arranged on a single plane. During long periods of typing, users need to move their fingers up and down frequently, which can easily lead to wrist and finger fatigue, and may even cause occupational diseases such as carpal tunnel syndrome. Utility Model Content

[0003] This invention provides a keyboard device with arc-shaped key arrangement, aiming to solve the problems of existing keyboard planar layouts that easily lead to user muscle fatigue and insufficient ergonomic support.

[0004] This utility model relates to a keyboard device with arc-shaped arranged keyboard keys, comprising: a housing, wherein an arc-shaped space with a concave shape is provided inside the housing; an arc-shaped positioning plate, wherein the arc-shaped positioning plate is arranged in an arc shape and matches the curvature of the arc-shaped space, and the arc-shaped positioning plate is disposed in the arc-shaped space; and keyboard keys, wherein the keyboard keys are disposed on the arc-shaped positioning plate such that the cross-section of the keyboard keys is arranged in an arc shape, and the top of the keyboard keys extends into the outer space of the housing.

[0005] As a further improvement of this utility model, the outer shell includes a base plate and a face frame. The top surface of the base plate is concave and arc-shaped. An arc-shaped positioning plate is disposed on the base plate. The face frame is arc-shaped and covers the top surface of the base plate. The face frame is provided with through holes for keyboard keys to pass through.

[0006] As a further improvement of this utility model, the arc-shaped positioning plate is provided with multiple flexible components, and the base plate is provided with support components corresponding to the multiple flexible components, with the flexible components disposed on the support components.

[0007] As a further improvement of this utility model, the base plate is rectangular, a first support part is provided on the first long side of the base plate, a second support part is provided on the second long side of the base plate, the first support part is higher than the second support part, and an arc-shaped connecting part is provided on both short sides of the base plate. The top of the arc-shaped connecting part is a concave arc-shaped edge, and one end is connected to the top of the first support part and the other end extends to the top of the second support part.

[0008] As a further improvement of this utility model, the curvature of the arc-shaped positioning plate is preset so that the central axes of the keyboard keys intersect at the same point.

[0009] As a further improvement of this utility model, the bottom surface of the arc-shaped positioning plate is provided with mounting areas corresponding to each row of keyboard keys. Each mounting area has a PCB board corresponding to each row of keyboard keys. The arc-shaped positioning plate has multiple rows of fixing holes, with each fixing hole fixing one keyboard key. As a further improvement of this utility model, the keyboard keys include key switches and keycaps. The key switches are fixedly installed in the fixing holes, and the keycaps are installed on the key switches, with the top of the keycaps extending into the outer space of the casing.

[0010] As a further improvement of this utility model, the top surface of each row of keycaps is inclined at a preset angle relative to its bottom surface, and the preset angle gradually increases along the spatial arrangement order from high to low.

[0011] The beneficial effects achieved by this utility model are as follows:

[0012] This invention provides a keyboard device with arc-shaped key layout. By designing the keyboard's input area as an arc structure, the overall key input area forms a three-dimensional structure with horizontally arranged arcs, which better conforms to the natural downward angle and movement habits of human fingers. The user's hand can naturally float above the keyboard, and the fingertips only need to move within the natural swing range of the knuckles to switch between different rows of keys, without the need for additional vertical lifting or pressing actions, effectively improving input efficiency and reducing muscle burden. At the same time, since the central axes of the keyboard keys intersect at the same point, the actuation force of each key is more consistent, improving the consistency and accuracy of typing feel. In addition, the arc-shaped matching design of the arc-shaped positioning plate and the base plate enhances structural stability. The preset tilt angle design of the top surface of each row of keycaps relative to the bottom surface further improves typing stability and the service life of the device. Compared with existing flat keyboards, the arc-shaped keyboard structure of this invention has significant advantages in ergonomics and can effectively reduce muscle fatigue caused by prolonged typing.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Figure 1 and Figure 2 A schematic diagram of one embodiment of the keyboard device with arc-shaped arranged keys according to this utility model is shown. Figure 1 This is a schematic diagram of the overall structure of the keyboard device with arc-shaped arranged keys. Figure 2 This is an exploded view of a keyboard device with arc-shaped key layout. Figure 1 and Figure 2 As shown, the keyboard device with arc-shaped keyboard keys includes: a housing 1, an arc-shaped positioning plate 2, and keyboard keys 3.

[0021] The outer casing 1 has an arc-shaped space with a concave shape.

[0022] The arc-shaped positioning plate 2 is set in an arc shape and matches the curvature of the arc space. The arc-shaped positioning plate 2 is set in the arc space.

[0023] The keyboard keys 3 are mounted on the arc-shaped positioning plate 2, so that the cross-section of the keyboard keys 3 is arranged in an arc shape, and the top of the keyboard keys 3 extends into the external space of the outer shell 1.

[0024] Specifically, the bottom surface of the outer casing 1 is designed as a flat structure for easy placement. The outer casing 1 has a concave arc-shaped space inside, so that when viewed from its cross-section, the top surface of the outer casing 1 presents a concave arc-shaped structure. To achieve an arc-shaped layout for the keyboard input area, the inner surface of the outer casing 1 has a concave arc-shaped space. An arc-shaped positioning plate 2, which supports the keyboard keys 3, is then placed within this arc-shaped space. Finally, the keyboard keys 3 are installed onto the arc-shaped positioning plate 2, resulting in the keyboard keys 3 being arranged in an arc shape in cross-section.

[0025] Furthermore, such as Figure 2As shown, the outer casing 1 includes a base plate 11 and a face frame 12. The top surface of the base plate 11 is concave arc-shaped, and an arc-shaped positioning plate 2 is disposed on the base plate 11. The face frame 12 is arc-shaped and covers the top surface of the base plate 11. The face frame 12 is provided with a through hole 121 for the keyboard keys 3 to pass through.

[0026] Preferably, the base plate 11 and the face frame 12 are detachably connected to facilitate assembly and maintenance.

[0027] Furthermore, such as Figure 2 As shown, in order to reduce the vibration generated when the keyboard key 3 is input, the arc-shaped positioning plate 2 is provided with multiple flexible parts 21, and the base plate 11 is provided with support parts 111 corresponding to the multiple flexible parts 21. The flexible parts 21 are set on the support parts 111.

[0028] Specifically, the flexible component 21 is preferably made of silicone. This flexible component 21 has shock-absorbing capabilities, used to absorb mechanical vibrations generated during input, thereby improving input stability and extending the device's lifespan.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, the base plate 11 is rectangular. A first support portion 112 is provided on the first long side of the base plate 11, and a second support portion 113 is provided on the second long side of the base plate 11. The first support portion 112 is higher than the second support portion 113. An arc-shaped connecting portion 114 is provided on both short sides of the base plate 11. The top of the arc-shaped connecting portion 114 is a concave arc-shaped edge, and one end is connected to the top of the first support portion 112, while the other end extends to the top of the second support portion 113.

[0030] Specifically, by setting the first support part 112 higher than the second support part 113, the overall shape of the keyboard device presents an arc structure from high to low, which conforms to the ergonomic principle and allows users to maintain a comfortable wrist posture and reduce fatigue when using the keyboard for a long time.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, the curvature of the arc-shaped positioning plate 2 is preset so that the central axes of the keyboard keys 3 intersect at the same point.

[0032] Specifically, by making the central axes of the keyboard keys 3 intersect at the same point, the arrangement of the keyboard keys 3 is made more in line with the natural curvature of the human hand. This ensures that the keycap surface and the user's natural downward pressing angle are consistent, reducing the interference of key angle deviation on input force and direction. It also avoids input errors or inconsistent key travel due to inconsistent angles, effectively improving typing accuracy and tactile stability. It is especially suitable for scenarios involving long-term input or multi-finger simultaneous typing, thus improving typing comfort.

[0033] Furthermore, such as Figure 2 and Figure 5 As shown, in order to improve the structural strength and modular maintenance performance of the keyboard, the bottom surface of the arc-shaped positioning plate 2 is provided with an installation area corresponding to each row of keyboard keys 3. The installation area is equipped with a PCB board 4 corresponding to each row of keyboard keys 3. The arc-shaped positioning plate 2 is provided with multiple rows of fixing holes 22, and each fixing hole 22 is used to fix one keyboard key 3.

[0034] Specifically, for each row of keyboard keys 3, this embodiment provides a corresponding PCB board 4. Given that this embodiment uses a curved spatial layout for the keyboard keys 3, the circuit board needs a similar structure to ensure accurate signal input for the keyboard keys 3. If a single circuit board were used in a traditional approach, the entire circuit board would need to be designed as a curved structure to match the layout of the keyboard keys 3. However, a curved circuit board is not a conventional structure, requiring mold making and design processes for production, significantly increasing production costs. In this embodiment, multiple PCB boards 4 are preferably used, each corresponding to a row of keyboard keys 3 (each row of keyboard keys 3 has the same tilt angle), to respectively realize the signal input function of each row of keyboard keys 3. Compared to using a single PCB board 4, the arrangement of multiple PCB boards 4 in this embodiment eliminates the need for separate mold making and design for the entire curved PCB board 4 during the production stage, significantly reducing production costs. Furthermore, compared to a single curved PCB board 4, it facilitates modular maintenance; if a single PCB board 4 is damaged, only the damaged PCB board 4 needs to be replaced, rather than the entire board. Additionally, the arrangement of multiple PCB boards 4 allows each PCB board 4 to be installed individually; each PCB board 4 is smaller and can be more securely installed and fixed compared to a single PCB board 4, thus improving structural strength.

[0035] Specifically, the mounting part 23 can be fixed by clips or screws to ensure that the PCB board 4 is firmly installed on the arc-shaped positioning plate 2 and will not loosen due to long-term use.

[0036] Furthermore, such as Figure 2 and Figure 5 As shown, the keyboard key 3 includes a key switch 31 and a keycap 32. The key switch 31 is fixedly installed in the fixing hole 22, and the keycap 32 is installed on the key switch 31. The top of the keycap 32 extends into the external space of the outer shell 1.

[0037] Specifically, the key switch 31 can adopt common mechanical switch structures, such as blue switch, red switch, brown switch and other different types of switches, to meet the needs of different users for key feel.

[0038] Furthermore, such as Figure 6 As shown, in order to improve typing comfort, the top surface of each row of keycaps 32 is tilted at a preset angle relative to its bottom surface, and the preset angle gradually increases along the spatial arrangement order from high to low.

[0039] It is important to understand that when a user types using the keyboard device of this embodiment, due to the arc-shaped arrangement of the keyboard keys 3, when the user's fingers strike the higher keys 3 (i.e., the keys 3 furthest from the user), the fingers are in an extended state; when the user's fingers strike the lower keys 3 (i.e., the keys 3 closer to the user), the fingers are in a bent state. To accommodate these changes in finger shape, in this embodiment, the top surface of each row of keycaps 32 is tilted at a preset angle relative to its bottom surface, and this preset angle gradually increases along the spatial arrangement from high to low. This allows the user's fingers to contact the upper surface of the keycaps 32 at a more natural angle, regardless of whether the fingers are extended or bent, improving typing comfort and accuracy. Figure 6 As shown in (A), the keycaps positioned higher have a smaller angle of inclination between their top and bottom surfaces; as Figure 6 As shown in (B), for keycaps in a lower position, the tilt angle of their top surface relative to their bottom surface is significantly larger.

[0040] This embodiment designs the keyboard's input area as an arc-shaped structure, creating a horizontally arc-shaped three-dimensional structure that better suits the natural downward angle and movement habits of the human finger. The user's hand can naturally float above the keyboard, and the fingertips only need to move within the natural swing range of the knuckles to switch between different columns, eliminating the need for additional vertical lifting or pressing movements, effectively improving input efficiency and reducing muscle strain. Simultaneously, because the central axes of the keyboard keys 3 intersect at the same point, the trigger force of each key is more consistent, improving the consistency and accuracy of typing feel. Furthermore, the arc-shaped matching design of the arc-shaped positioning plate 2 and the base plate 11 enhances structural stability; the preset tilt angle design of the top surface of each row of keycaps 32 relative to the bottom surface further improves typing stability and the device's lifespan. Compared to existing flat keyboards, the arc-shaped keyboard structure of this invention has significant advantages in ergonomics, effectively reducing muscle fatigue caused by prolonged typing.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
