Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, in particular to an anti-skid keyboard armrest cover structure. Background Art

[0002] 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.

[0003] In order to solve this problem, keyboard armrests came into being. However, the existing armrests on the market adopt a method of laying sponge on the upper cover, and then wrapping leather cloth or elastic cloth on the sponge. Since the leather cloth or elastic cloth is only fixed to the edge of the upper cover at the edge, but there is no fixation in the middle area of ​​the leather cloth or elastic cloth, in actual use, when the wrist is placed on the keyboard armrest and there is a slight lateral deviation during typing, the middle part of the leather cloth or elastic cloth will shift sideways because it is not fixed, and wrinkles will form in the direction of the lateral shift, causing discomfort at the wrist, seriously affecting the user experience of the keyboard armrest, and the defects are obvious. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a non-slip keyboard armrest cover structure which can effectively prevent the leather cloth or elastic cloth on the surface of the keyboard armrest from lateral displacement and improve the typing comfort.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a non-slip keyboard armrest upper cover structure, comprising an upper cover body, a wear-resistant surface layer covering the upper cover body, and a filling layer filled between the upper cover body and the wear-resistant surface layer, a hot melt adhesive layer with a thickness of 1-2 mm is provided between the upper surface and the lower surface of the filling layer, and the hot melt adhesive layer covers the entire upper surface of the upper cover body and the entire inner surface of the wear-resistant surface layer.

[0006] Preferably, the filling layer is made of breathable sponge material, the wear-resistant surface layer is made of breathable elastic fabric, and the hot-melt adhesive layer is provided with ventilation holes.

[0007] Preferably, the filling layer is made of a breathable sponge material, the wear-resistant surface layer is made of a leather material, and both the wear-resistant surface layer and the hot-melt adhesive layer are provided with air holes.

[0008] Preferably, the upper cover body, the filling layer and the hot melt adhesive layer are formed by heat-pressing and bonding through a heating and pressing process.

[0009] Preferably, the edge of the wear-resistant surface layer is provided with a reinforced edge by extending outward, and the reinforced edge is turned inward to the lower edge of the upper cover body.

[0010] The beneficial effect of the utility model is that the utility model provides a non-slip keyboard armrest upper cover structure. In actual production and manufacturing, the upper cover body, the filling layer and the hot melt adhesive layer are formed by hot pressing and bonding through a heating and pressing process. It has the advantages of easy automatic bonding, firm and reliable bonding and high assembly efficiency. The soft coating layer is bonded to the base material layer by a hot pressing process of hot melt adhesive, which not only greatly simplifies the bonding process and assembly difficulty of the soft coating layer, but also the hot melt adhesive layer with a thickness of 1-2 mm can not only achieve the bonding strength between the upper cover body, the filling layer and the wear-resistant surface layer, but also avoid the hardening of the wear-resistant surface layer caused by excessive addition of hot melt adhesive and affect the comfort. In actual use, it can also effectively prevent the middle part of the soft coating layer and the base material layer from being misaligned and wrinkled due to lack of fixation, and affect the comfort of the wrist, effectively avoid sliding at the wrist, and significantly improve the use experience.

[0014] 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.

[0015] like Figures 1 to 3 As shown, a non-slip keyboard armrest upper cover structure includes an upper cover body 1, a wear-resistant surface layer 2 coated on the upper cover body 1, and a filling layer 3 filled between the upper cover body 1 and the wear-resistant surface layer 2, and a hot melt adhesive layer 4 with a thickness of 1-2 mm is provided between the upper surface and the lower surface of the filling layer 3, and the hot melt adhesive layer 4 covers the entire upper surface of the upper cover body 1 and the entire inner surface of the wear-resistant surface layer 2.

[0016] In actual manufacturing, the upper cover body 1, the filling layer 3 and the hot melt adhesive layer 4 are hot-pressed and bonded by a heating and pressing process. It has the advantages of easy automatic bonding, firm and reliable bonding and high assembly efficiency. The soft coating layer is bonded to the base material layer by a hot-pressing process of hot melt adhesive, which not only greatly simplifies the bonding process and assembly difficulty of the soft coating layer, but also the hot melt adhesive layer 4 with a thickness of 1-2 mm can not only achieve the bonding strength between the upper cover body 1, the filling layer 3 and the wear-resistant surface layer 2, but also avoid the hardening of the wear-resistant surface layer 2 due to excessive addition of hot melt adhesive and affect the comfort. In actual use, it also effectively prevents the middle part of the soft coating layer and the base material layer from being misaligned and wrinkled due to lack of fixation, and affects the comfort of the wrist, effectively avoiding slippage at the wrist, and significantly improving the use experience.

[0017] In this embodiment, the filling layer 3 is made of breathable sponge material, the wear-resistant surface layer 2 is made of breathable elastic fabric, and the hot melt adhesive layer 4 is provided with ventilation holes. Due to the design of the ventilation holes, even if the user's wrist contacts the upper cover of the armrest for a long time during typing, there will be no problem of sweat accumulation due to airtightness, and the user will feel more comfortable.

[0018] It should be supplemented that: the filling layer 3 is made of breathable sponge material, the wear-resistant surface layer 2 is made of leather material, and the wear-resistant surface layer 2 and the hot-melt adhesive layer 4 are both provided with ventilation holes, which can also achieve the above-mentioned technical effect.

[0019] In this embodiment, the edge of the wear-resistant surface layer 2 is provided with a reinforced edge 5 extending outward, and the reinforced edge 5 is turned inward to the lower edge of the upper cover body 1. When assembled with the bottom shell of the keyboard armrest, the reinforced edge 5 is clamped between the upper cover body 1 and the bottom shell, which not only realizes the all-round wrapping of the upper cover body 1 of the keyboard armrest, and the texture and comfort are significantly improved, but also strengthens the connection tightness between the wear-resistant surface layer 2 and the upper cover body 1, which is more reliable and durable.
