Description

A keyboard with armrests and a protective cover Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a keyboard with armrests and a protective cover. Background Technology

[0002] In modern office and daily life scenarios, keyboards are widely used as an important input device. During daily use, keyboards are exposed to environmental factors such as dust and liquid splashes, which can easily lead to key malfunctions, short circuits, and other problems, significantly impacting the keyboard's lifespan and performance. Furthermore, prolonged use of the keyboard for typing can easily cause wrist and arm fatigue, and may even lead to wrist joint problems, affecting the user's health and work efficiency.

[0003] Currently, most keyboard protection measures on the market use separate dust covers, which require additional placement and storage during use, making them inconvenient to use and prone to loss. While improving keyboard comfort often involves a separate wrist rest in front of the keyboard, these wrist rests are detachable from the keyboard, leading to unstable placement and inconvenience in carrying them. Furthermore, separate dust covers and wrist rests increase user costs and take up more desk space. Therefore, there is an urgent need for a keyboard design that integrates protection and comfortable support, while also being easy to use and carry. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a keyboard with armrests and a protective cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a keyboard with armrests and a protective cover, including a keyboard body, a first folding plate, and a second folding plate. The first folding plate and the second folding plate are respectively connected to the front and rear sides of the keyboard body. Both the first folding plate and the second folding plate have multiple folding parts. When the first folding plate and the second folding plate are unfolded and located on the key surface of the keyboard body, they constitute the protective cover structure of the keyboard body. When the folding part of the first folding plate is folded into a geometric shape at the front edge of the keyboard body, it constitutes the armrest structure of the keyboard body.

[0007] Furthermore, the first folding plate includes a first connector, a first folding portion, a second folding portion, a third folding portion, and a fourth folding portion arranged sequentially. The first connector is connected to the front side of the keyboard body. When the first folding plate is folded into an armrest structure, the second folding portion, the third folding portion, and the fourth folding portion together form a geometric shape with a triangular cross-section, and the fourth folding portion abuts against the junction of the first folding portion and the second folding portion.

[0008] Furthermore, the first connector is detachably connected to the front side of the keyboard body.

[0009] Furthermore, the first connector is provided with a first magnetic attraction element, and the front side of the keyboard body is provided with a second magnetic attraction element, and the first magnetic attraction element and the second magnetic attraction element can attract each other magnetically.

[0010] Furthermore, the width of the first fold is smaller than the width of the second fold, the third fold, or the fourth fold, and larger than the key height of the keyboard body.

[0011] Furthermore, the second folding plate includes a second connector, a fifth folding portion, and a sixth folding portion arranged in sequence, and the second connector is connected to the rear side of the keyboard body.

[0012] Furthermore, when the first folding plate and the second folding plate unfold and cooperate to form the protective cover structure, the sixth folding part comes into contact with the fourth folding part.

[0013] Furthermore, the sixth fold is provided with a third magnetic attractor, and the fourth fold is provided with a fourth magnetic attractor, and the third magnetic attractor and the fourth magnetic attractor can attract each other magnetically.

[0014] Furthermore, the front of the keyboard body is provided with a limiting groove, and the side of the sixth fold that contacts and cooperates with the fourth fold can be inserted into the limiting groove.

[0015] Furthermore, the top of the second connector protrudes from the front of the keyboard body.

[0016] The beneficial effects of this utility model compared with the prior art are as follows: A keyboard with an armrest and a protective cover includes a keyboard body, a first folding plate, and a second folding plate. The first and second folding plates are respectively connected to the front and rear sides of the keyboard body. Both the first and second folding plates have multiple folds. When both the first and second folding plates are unfolded and positioned on the key surface of the keyboard body, they form a protective cover structure for the keyboard body. When the folds of the first folding plate are folded into a geometric shape at the front edge of the keyboard body, they form an armrest structure for the keyboard body. This utility model, through the cooperation of the first and second folding plates, not only forms an effective protective cover structure, which can comprehensively resist external interference such as dust and liquid splashes, preventing keyboard malfunctions caused by external factors, but also significantly improves the keyboard's lifespan and operational stability. Furthermore, it can quickly transform into an armrest structure, providing comfortable support for the user's wrists and arms, effectively relieving fatigue caused by prolonged keyboard use, reducing the risk of wrist joint diseases, and improving user comfort and health. Furthermore, the keyboard's armrest and protective cover structures are both achieved through folding panels, eliminating the need for additional dust covers and wrist rests. This not only reduces user costs but also saves desktop space. The folding panels are connected to the keyboard body, making them easy to carry and use. This solves the problems of existing separate protective and support components being easily lost or unstable when placed, greatly improving the convenience and practicality of the keyboard.

[0030] As shown in Figures 1 to 3, this utility model embodiment provides a keyboard with armrests and a protective cover, including a keyboard body 1, a first folding plate 2, and a second folding plate 3. The keyboard body 1 is a conventional rectangular computer keyboard. The first folding plate 2 and the second folding plate 3 are respectively connected to the front and rear sides of the keyboard body 1. Both the first folding plate 2 and the second folding plate 3 have multiple folds. When both the first folding plate 2 and the second folding plate 3 are unfolded and located on the key surface of the keyboard body 1, they constitute the protective cover structure of the keyboard body 1. When the folds of the first folding plate 2 are folded into a geometric shape at the front edge of the keyboard body 1, they constitute the armrest structure of the keyboard body 1.

[0031] The protective cover structure, formed by unfolding the first folding plate 2 and the second folding plate 3, effectively prevents dust accumulation in the gaps between the keyboard keys and avoids liquid spills that could cause short circuits or other malfunctions, significantly improving the keyboard's lifespan and stability. For example, in an office setting, it reduces damage caused by spilled coffee or other beverages; in a home environment, it prevents children from dropping food crumbs into the keyboard while playing. Simultaneously, the armrest structure formed by folding the first folding plate 2 is ergonomically designed, providing comfortable support for the user's wrists and arms. During prolonged typing or gaming, it effectively relieves wrist fatigue, reduces the risk of wrist joint diseases (such as mouse hand), and improves user comfort. Furthermore, since both the armrest and protective cover structures are achieved through folding plates, there is no need for additional dust covers and wrist rests, reducing user costs, saving desktop space, and making the keyboard easy to carry and use. This solves the problems of existing separate protective and support components being easily lost or unstable when placed.

[0032] As shown in Figure 2, the first folding plate 2 includes a first connector 21, a first folding part 22, a second folding part 23, a third folding part 24, and a fourth folding part 25 arranged sequentially. The first connector 21 is detachably connected to the front side of the keyboard body 1. When the first folding plate 2 is folded into an armrest structure, the second folding part 23, the third folding part 24, and the fourth folding part 25 together form a geometric shape with a triangular cross-section, and the fourth folding part 25 abuts against the junction of the first folding part 22 and the second folding part 23.

[0033] In one embodiment, the first connector 21 is a rectangular thin plate with four evenly distributed first magnetic attractors on its back side. Correspondingly, four second magnetic attractors are embedded in the front side of the keyboard body 1. The first and second magnetic attractors are neodymium iron boron magnets, which provide stable attraction and are easy to disassemble. The first folding part 22, the second folding part 23, the third folding part 24, and the fourth folding part 25 are all rectangular plates, and the folding parts are connected by flexible connecting strips that can be bent, allowing for flexible folding while maintaining a certain structural strength.

[0034] When the armrest structure is needed, the second fold 23 is folded counterclockwise around the connection between the first fold 22 and the second fold 23; then, the third fold 24 is folded counterclockwise around the connection between the second fold 23 and the third fold 24, forming an angle with the second fold 23; finally, the fourth fold 25 is folded counterclockwise around the connection between the third fold 24 and the fourth fold 25, bringing it abutting against the junction of the first fold 22 and the second fold 23. At this point, the second fold 23, the third fold 24, and the fourth fold 25 together form a geometric shape with an equilateral triangle cross-section, providing stable and comfortable support for the user's wrist.

[0035] In one embodiment, the first connector 21 and the front side of the keyboard body 1 can also be connected by a snap-fit ​​method, that is, the first connector 21 is provided with four elastic snaps, and the front side of the keyboard body 1 is provided with corresponding slots.

[0036] The armrests, formed by folding into different geometric shapes, can provide support tailored to user needs and usage scenarios, effectively relieving wrist fatigue caused by prolonged keyboard use and reducing the risk of joint pain caused by prolonged wrist suspension or improper support.

[0037] In one embodiment, the width of the first fold 22 is smaller than the width of the second fold 23, the third fold 24, or the fourth fold 25, but larger than the height of the keys on the keyboard body 1. This design ensures that when unfolded to form a protective cover, the second fold 23, the third fold 24, and the fourth fold 25 naturally cover the surface of the keyboard keys, avoiding the problem of incomplete folding caused by insufficient width of the first fold 22.

[0038] As shown in Figure 2, the second folding plate 3 includes a second connector 31, a fifth folding part 32 and a sixth folding part 33 arranged in sequence. The second connector 31 is connected to the rear side of the keyboard body 1.

[0039] The second connector 31 is a long strip of plastic plate, which is fixed to the rear side of the keyboard body 1 with strong double-sided adhesive. Its position is adapted to the width of the keyboard to ensure that the second folding plate 3 can completely cover the rear half of the keyboard when unfolded. The fifth folding part 32 and the sixth folding part 33 are both rectangular plastic plates. The width of the sixth folding part 33 is greater than the width of the fifth folding part 32. The two are connected by a flexible PVC folding strip, which can be flexibly bent and is not easy to break.

[0040] Three third magnetic attractors are embedded near the edge of the sixth folding part 33 and are arranged in a straight line; correspondingly, when the first folding plate 2 is unfolded to form the front half of the protective cover, the edge of the fourth folding part 25 is provided with a fourth magnetic attractor corresponding to the position of the third magnetic attractor.

[0041] When keyboard protection is needed, unfold the second folding plate 3 from the back of the keyboard. Using the connection between the second connector 31 and the fifth folding part 32 as an axis, flip the fifth folding part 32 upwards to a horizontal position. Then, using the connection between the fifth folding part 32 and the sixth folding part 33 as an axis, fold the sixth folding part 33 forward until it contacts the fourth folding part 25 of the first folding plate 2. At this time, the third and fourth magnetic components attract each other, making the protective cover tightly closed, effectively preventing dust and liquid from entering the keyboard.

[0042] In one embodiment, a limiting groove 11 is provided on the front of the keyboard body 1, and the side of the sixth folding part 33 that contacts and cooperates with the fourth folding part 25 can be inserted into the limiting groove 11. As shown in Figure 2, Figure 2 illustrates the state in which the bottom of the sixth folding part 33 is inserted into the limiting groove 11. In this state, the sixth folding part 33 is in an inclined vertical state, which is equivalent to the function of a shield to meet the special needs of the user when operating the keyboard.

[0043] As shown in Figure 1, when the second folding plate 3 is folded into the state shown in Figure 1, the sixth folding part 33 is in an upright state, and the lower side of the sixth folding part 33 is magnetically connected to the side of the second connector 31 so that the sixth folding part 33 can maintain an upright state. The sixth folding part 33 in the upright state can be used as a backrest, that is, lightweight electronic devices such as mobile phones and tablets can be placed at a certain angle in front of the sixth folding part 33. The upper side of the electronic device is in contact with the front side of the sixth folding part 33, and the lower side of the electronic device is stuck in the limiting groove 11, thereby making it convenient for the user to view the content on the electronic device.

[0044] In one embodiment, the top of the second connector 31 protrudes from the front of the keyboard body 1. This design allows the protruding top of the second connector 31 to reasonably avoid keyboard keys or conform to the shape of the keyboard surface, preventing interference with the keyboard during the unfolding and closing of the folding panel, thus improving the product's adaptability and compatibility.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
