Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of keyboards, in particular to a high-comfort curved keyboard. Background Art
[0002] When using a traditional computer keyboard, people's left and right palms are usually placed on the keyboard, keeping a certain angle with the arms, rather than parallel in a natural state. This unnatural posture can easily lead to hand fatigue and discomfort, and often causes problems such as finger soreness, stiffness, and inflexibility. Therefore, we urgently need a technical solution to solve this problem.
[0003] With the popularity of computers and keyboards, people increasingly rely on keyboards for work and daily life. However, long-term keyboard operation has a negative impact on hand health. The design of traditional keyboards does not take into account the principles of ergonomics, resulting in unnatural hand postures when users use the keyboard, increasing the burden on hand muscles, which in turn causes a series of problems.
[0004] In order to solve this problem, various ergonomic keyboards have appeared on the market. However, people have become accustomed to using conventional keyboards. The excessive pursuit of ergonomic keyboards has caused strong discomfort in actual applications, making it difficult for most ergonomic keyboards to be popularized. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a high-comfort curved keyboard which adopts a certain degree of ergonomic design, can improve the comfort of keyboard use and does not completely abandon the habit of many years of use.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a high-comfort curved keyboard, comprising a bottom shell, an armrest pad arranged at the rear of the bottom shell, and a key seat arranged at the front of the bottom shell, the key seat comprising a main key area and a keypad key area, the main key area gradually thickens from both ends to the middle, the armrest pad comprises a hand rest area corresponding to the main key area and an extension area corresponding to the keypad key area, the front edge of the hand rest area is equal to the rear edge of the main key area in thickness, the left edge, the right edge and the rear edge of the hand rest area gradually increase in thickness to the front edge, and the thickness of the extension area is equal to the thickness of the right edge of the hand rest area;
[0007] The armrest pad comprises a base material layer connected to the bottom shell and a soft covering layer covering the base material layer; a hot melt adhesive film layer is arranged between the base material layer and the soft covering layer.
[0008] Preferably, the area where the thickness of the armrest pad gradually increases is a curved transition.
[0009] Preferably, the thickness of the front edge of the bottom shell is greater than the thickness of the rear edge.
[0010] Preferably, the middle portion of the main button area is bent inwardly into a fan shape.
[0011] Preferably, the keypad key area is a rectangle of equal thickness, the width of the keypad key area is constant, and the thickness of each part of the keypad key area is equal.
[0012] The beneficial effect of the utility model is that the utility model provides a high-comfort curved keyboard. Due to the design of the armrest pad, the comfort of the wrist is effectively solved, and it only bulges upward within the range of the main keyboard area, which conforms to the user's habit of operating both hands within the range of the main keyboard area for a long time, and the comfort is relatively high. The soft coating layer is bonded to the base layer by a hot-melt adhesive hot-pressing process, which not only greatly simplifies the bonding process and assembly difficulty of the soft coating layer, but also effectively prevents the middle part of the soft coating layer from being misaligned and wrinkled due to the lack of fixation with the base layer, and affects the comfort of the wrist, effectively avoiding slippage at the wrist, and significantly improving the user experience.

[0017] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0018] like Figures 1 to 4As shown, a high-comfort curved keyboard comprises a bottom shell 1, an armrest pad 2 arranged at the rear of the bottom shell 1, and a key base 3 arranged at the front of the bottom shell 1, wherein the key base 3 comprises a main key area 31 and a small keypad key area 32, wherein the main key area 31 gradually thickens from both ends to the middle, and the armrest pad 2 comprises a hand rest area 21 corresponding to the main key area 31 and an extension area 22 corresponding to the small keypad key area 32, wherein the thickness of the front edge of the hand rest area 21 and the rear edge of the main key area 31 are The thickness of the left edge, right edge and rear edge to the front edge of the hand support area 21 gradually increases, and the thickness of the extension area 22 is equal to the thickness of the right edge of the hand support area 21; the armrest pad 2 includes a base material layer 23 connected to the bottom shell 1 and a soft covering layer 24 covering the base material layer 23; a hot melt adhesive film layer 25 is provided between the base material layer 23 and the soft covering layer 24, and the soft covering layer 24 is bonded to the surface of the base material layer 23 by a hot pressing process.
[0019] In actual application, the design of the armrest pad 2 effectively solves the problem of the comfort of the wrist, and it only bulges upward within the range of the main keyboard area, which is in line with the user's habit of operating with both hands within the range of the main keyboard area for a long time, and is relatively comfortable. The soft coating layer 24 is bonded to the base layer 23 by a hot-melt adhesive hot-pressing process, which not only greatly simplifies the bonding process and assembly difficulty of the soft coating layer 24, but also effectively prevents the middle part of the soft coating layer 24 from being misaligned and wrinkled due to the lack of fixation with the base layer 23, and the problem of affecting the comfort of the wrist, effectively avoiding slippage at the wrist, and significantly improving the user experience.
[0020] In this embodiment, the area where the thickness of the armrest pad 2 gradually increases is a curved surface transition, which further improves the comfort of the armrest pad 2.
[0021] In this embodiment, the thickness of the front edge of the bottom shell 1 is greater than the thickness of the rear edge. After adopting this structural design, the curved keyboard as a whole has a certain inclination angle, which is convenient for the user's fingers to tap the keyboard keys, reduces finger fatigue, and improves the accuracy and comfort of fingers when typing.
[0022] In this embodiment, the middle part of the main key area 31 is bent inward into a fan shape. After adopting this structural design, the parts of the main key area 31 corresponding to the left and right hands are inclined outward. The inclination angle just matches the angle between the left and right hands when the hands stay on the main keyboard area. The user's hands tend to be more naturally relaxed when typing. Even if the user uses the keyboard to type for a long time, it is not easy to feel hand soreness and fatigue, which is very practical.
[0023] In this embodiment, the keypad key area 32 is a rectangle of equal thickness, the width of the keypad key area 32 is unchanged, and the thickness of each part of the keypad key area 32 is equal, so that the user can identify the positions of the keypad key area 32 and the main key area 31 without visual observation.
