The separately provided keycap waterproof layer 30 is used for waterproofing the keycap area. The first fitting part 31 and the second fitting part 32 are connected to The fitting of the accommodating part 21 realizes the waterproofing of the keycap area, preventing moisture and dust from entering, and does not affect the use of the keycap 11 . This invention effectively solves the problem in the prior art that the keyboard has poor waterproof and dustproof performance, which seriously affects the service life of the keyboard.

It should be noted that the main waterproof layer 20 and the keycap waterproof layer 30 are both integrally formed structures. This arrangement makes the structures of the two simple and compact, and they are easy to cooperate. The main waterproof layer 20 and the keycap waterproof layer 30 of the same set are interchangeable. It has strong properties and is conducive to production and processing. In this embodiment, the fit means that the two parts may be in contact with each other, but it does not limit whether the two parts that are attached to each other are fixedly connected. After the assembly is completed, the two parts that are attached to each other are compact in structure and difficult to generate bubbles. This way When the keycap 11 is pressed, a certain gap can be generated in the partially fitting area to adapt to the deformation of the keycap waterproof layer 30 when the keycap 11 is pressed. At the same time, the integrally formed keycap waterproof layer 30 protects the keycap 11 and the gap between the keycap 11 from being affected by moisture or dust. This arrangement can reduce the amount of space required between the keycap 11 and the keyboard body 12 The waterproof and dustproof setting transfers the waterproof and dustproof requirements to the keycap waterproof layer 30 so that the keycap 11 and the keyboard body 12 can cooperate more closely. The accommodating part 21 is specifically a recessed accommodating cavity on the main body waterproof layer 20. The recessed accommodating cavity can completely place the first fitting part 31 and the second fitting part 32 of the keycap waterproof layer 30 into the accommodating cavity, so that The arrangement can provide the user with a visual effect that the main waterproof layer 20 and the keycap waterproof layer 30 are on the same plane. Furthermore, such an arrangement facilitates the subsequent setting of patterns or patterns on the surface of the keyboard, and the pattern display effect on the same plane is better.

In another optional embodiment, before the keycap waterproof layer 30 comes into contact with the keycap 11 , glue can be applied on the first fitting portion 31 to connect the top pressing area of the keycap 11 with the first fitting portion. 31 is closely combined, specifically, glue application can be performed, and after bonding, the glue is solidified through high-temperature baking, so that the first bonding portion 31 is tightly bonded with the keycap 11 .

The second accommodation structure 212 is attached to the second fitting part. 32 fit. The second accommodation structure 212 arranged in a mesh shape can completely isolate the keycap 11 according to the fit of the second fitting portion 32 . After the second fitting portion 32 is combined with the second accommodation structure 212 , the first fitting portion 31 Divided into multiple corresponding single keycaps 11, this arrangement makes the waterproof layers between the keycaps 11 independent. When the key is pressed down, the independent first fitting portion 31 is close to the deformation of its own side wall to adapt to the keycap 11. When pressed down, the adjacent keycap 11 is prevented from being pressed down, which can effectively improve the accuracy of tapping the keycap 11. At the same time, such an arrangement can connect the second fitting portion 32 with the second accommodation structure. 212 better fit, ensuring a tight combination between the keycap waterproof layer 30 and the main body waterproof layer 20, making the structure more compact.

As shown in FIGS. 1 to 6 , in the technical solution of Embodiment 1, the accommodating part 21 includes a first accommodating structure 211 , the keycap waterproof layer 30 further includes a third fitting part 33 , and the first accommodating structure 211 surrounds a plurality of The keycap 11 is provided with a third fitting part 33 surrounding the first fitting part 31 and the second fitting part 32 , and the third fitting part 33 is fitted with the first receiving structure 211 . This arrangement seals all the keycaps 11 , and the integrally formed keycap waterproof layer 30 completely prevents moisture or dust from entering the gaps between the keycaps 11 . It should be noted that, in order to further improve the sealing effect, the third fitting part 33 can be completely fitted with the first accommodation structure 211, and the width of the first accommodation structure 211 is greater than the width of the third fitting part 33, so that the side walls of the accommodation part 21 A certain groove is left between the keyboard and the third fitting portion 33 . Filling the groove with sealant further blocks the entry of water vapor and other substances. This arrangement is more conducive to the waterproof performance of the keyboard. It should be noted that since the second accommodating structure 212 needs to surround the entire keycap area, the second accommodating structure 212 has a larger frame, and the corresponding first accommodating structure 211 is arranged around the above-mentioned frame, which can improve the waterproof layer of the main body. Better adhesion between 20 and keycap waterproof layer 30. Furthermore, the first accommodation structure 211 and the second accommodation structure 212 may be an integrally formed structure, which is more conducive to the waterproof and dustproof performance of the waterproof layer.

As shown in Figures 3, 4 and 7, in the technical solution of Embodiment 1, the keyboard further includes a support assembly 40. The support assembly 40 includes a support layer 42. The support layer 42 is disposed between the keyboard body 12 and the body waterproof layer 20. During this time, the support layer 42 is attached to the keyboard body 12. The support layer 42 includes a third accommodation structure 421. The third accommodation structure 421 is mesh-shaped. The third accommodation structure 421 forms a plurality of third through holes 422. Each keycap 11 is connected to the keyboard body 12. Each third through hole 422 is provided in one-to-one correspondence, and each keycap 11 can pass through the third receiving structure 421 and fit with the first fitting portion 31 . The support layer 42 is provided to support the main body waterproof layer 20 and protect the keyboard body 12 within the support layer 42, thereby playing a role in overall protection. The third accommodation structure 421 is mesh-shaped to provide support for the second accommodation structure 212, and at the same time isolates the main waterproof layer 20 from the keyboard body 12. The keyboard body 12 is provided with electronic components, and is wrapped with the support layer 42. The remaining parts are isolated and can form a certain seal. At the same time, it can provide more material choices for the main waterproof layer 20 to adapt to more waterproof materials with higher plasticity, which can increase the design scope of the overall appearance of the keyboard and reduce design restrictions. It should be noted that the sizes of the first through hole 213 and the third through hole 422 are in clearance fit with the corresponding keycap 11 , thereby avoiding restrictions on the use of the keycap 11 by the support layer 42 or the main waterproof layer 20 .

As shown in Figures 8 and 9, in the technical solution of Embodiment 2 provided by this invention, the main waterproof layer 20 and the keycap waterproof layer 30 are an integrated structure, and the first accommodation structure 211, the second accommodation structure 212, the second sticker The joint part 32 and the third joint part 33 are integrated. The support assembly 40 also includes a first support structure 41. The first support structure 41 is a mesh structure. The first support structure 41 and the second joint part 32 are bonded. A support structure 41 and the second fitting portion 32 are both disposed in the gap between adjacent keycaps 11 , and the first support structure 41 is an integrally formed structure. The first fitting portion 31 fits the keycap 11 to avoid the sliding phenomenon between the pressing area of the main waterproof layer 20 and the keycap 11, and avoids the keycap area of the main waterproof layer 20 from moving. The first support structure 41 and The arrangement of the second fitting part 32 increases the structural strength of the main waterproof layer corresponding to the gap between the keycaps 11 and increases the weight of the second fitting part 32. When the keycaps 11 are pressed down, the first fitting The pulling ability of the part 31 to the second fitting part 32 is greatly reduced, so that the position where the main waterproof layer 20 needs to be deformed is on the side wall of the keycap 11, which isolates the pulling of the waterproof layer of the adjacent keycap 11, thereby solving the problem of keyboard pressing. Problems arising from associated phenomena. This invention effectively solves the problem in the prior art that when the main waterproof layer 20 of the keyboard is a whole, when the key cap is pressed, the surrounding key caps will be connected, resulting in low keyboard input accuracy.

It should be noted that the main waterproof layer 20 adopts an integrated structure to achieve optimal waterproof performance. This arrangement can reduce the waterproof and dustproof treatment required inside the keyboard, simplifying the internal structure and making it more conducive to production. In this embodiment, the fit means that the two parts may be in contact with each other, but it does not limit whether the two parts that are attached to each other are fixedly connected. After the assembly is completed, the two parts that are attached to each other are compact in structure and difficult to generate bubbles. This way When the keycap 11 is pressed, a certain gap can be generated in the partially fitting area to adapt to the deformation of the main waterproof layer 20 when the keycap 11 is pressed. The first support structure 41 adopts an integrated structure, which is beneficial to improving its own structural strength. At the same time, when the first support structure 41 is integrated, the tensile force on the second fitting portion 32 in a single gap can be increased, and the overall structure The second fitting part 32 is also formed into a whole, and the first fitting part 31 and the waterproof layer on the side of the keycap 11 are separated independently, which further avoids the interlocking movement of adjacent keycaps and improves the accuracy of tapping the keycap 11 sex. Specifically, the first support structure 41 includes a support frame 412. A second through hole 411 is formed between the support frame 412. The second through hole 411 is used for the keycap 11 to pass through. There are multiple second through holes 411 and the second through hole 411 is The through hole 411 has a clearance fit with the corresponding keycap 11, and the support frame 412 connects the entire second fitting part 32 to form a whole, increasing the anti-deformation ability of the second fitting part 32, and cooperating with the first fitting part 31 and The fitting of the top of the keycap 11 causes all the deformation of the waterproof layer required for the keycap 11 to be pressed down on the waterproof layer on the side wall of the keycap 11, so that the waterproof layer of the adjacent keycap 11 will not be pressed down together, further ensuring that Typing accuracy.

As shown in FIGS. 8 to 10 , in the technical solution of the second embodiment, the support assembly 40 further includes a support layer 42 , the support layer 42 is disposed between the first support structure 41 and the keyboard body 12 , and the support layer 42 and the keyboard body 12 12, the keycap 11 can fit through the support layer 42 and the first fitting portion 31. The support layer 42 is provided to isolate the keyboard body 12 from the first support structure 41 .

As shown in FIG. 8 , in the technical solution of the second embodiment, a fitting gap is set between the first support structure 41 and the third receiving structure 421 , and the height of the fitting gap is H, 0.15 mm ≤ H ≤ 0.5 mm. The purpose of setting the fitting gap is that when the first support structure 41 is bonded under the second fitting part 32, such a setting enhances the overall deformation resistance of the second fitting part 32, thereby making the main waterproof layer 20 on the keycap 11 is pressed, its deformation position is between the first support structure 41 and the side wall of the keycap 11, thereby preventing the second fitting portion 32 from driving the adjacent keycaps 11 to move, and the interlocking between the main waterproof layer 20 and the keycap 11. There is a gap between them, thereby improving the accuracy of pressing the keycap 11 and the pressing feel. It should be noted that the height setting of the fitting gap needs to be set according to the actual pressing depth of the keycap 11. If the height of the fitting gap is too high, the deformation area of the main waterproof layer 20 will be too large, and the elastic deformation will fail, resulting in permanent damage to the waterproof layer. There is a risk of deformation. At the same time, the first support structure 41 is subject to a large force, and there is also a risk of damage. If the height of the fit gap is selected to be small, the deformation area of the main waterproof layer 20 will be relatively small, and the first support structure 41 will easily come into contact with the components below, which will cause the bottom components and the first support structure 41 to Relative motion between them causes wear. In this embodiment, the selected height of the fitting gap is 0.2 mm. On the one hand, the setting of the fitting gap is to provide an activity space for the first support structure 41 so that the first support structure 41 can stretch the second fitting portion 32 downward. , so that the fitting effect of the main waterproof layer 20 is better. On the other hand, the first support structure 41 has a certain amount of deformation. Setting the fitting gap can make the deformation amount of the first support structure 41 within the height range of the fitting gap. Further The keyboard body 12 is protected from the ground. This setting can improve the comfort of using the keyboard. It should be noted that the depth of the gap between the keycaps 11 is relatively deep. When the main waterproof layer 20 is installed on the keycaps, the keycaps can easily drive the adjacent keycaps 11 during use. Therefore, in the first step through the keyboard model, the main waterproof layer 20 is pressed into the shape of the keyboard. In the second step, the first support structure 41 is used to fix the shape. There is a gap of 0.2mm between the first support structure 41 and the support layer 42. It is convenient for the keycap 11 to move up and down when pressed.

It should be noted that in the technical solution of the second embodiment, in order to ensure the feel of the keycap 11 when pressed, the main waterproof layer 20 is made of a thin flexible material, and the thinner main waterproof layer 20 is pre-pressed into the shape of the keycap. After that, the fit with the keycap 11 is better, and the first fit part 31 and the keycap 11 are better fitted to avoid the gap between the pressing area of the main waterproof layer 20 and the keycap 11, solving the existing problem of Technical problem is that there is a gap between the medium-thick main body waterproof layer 20 and the keycap 11, resulting in poor hand feel. In an optional embodiment, the thickness of the main waterproof layer 20 ranges from 0.01 mm to 0.2 mm. Such a thickness can ensure precise structure during the molding process, so as to facilitate subsequent better assembly of the keyboard. The setting of the waterproof layer also needs to consider the actual pressing feel of the keycap 11. When the thickness of the main waterproof layer 20 is between 0.01mm and 0.1mm, even if the main waterproof layer 20 is added to the keycap 11, it will not affect the actual keycap. 11 pressing feel, and the main body waterproof layer 20 within this range facilitates processing and production. Furthermore, when the thickness of the main waterproof layer 20 is between 0.01mm and 0.05mm, the thickness of the main waterproof layer 20 is further reduced, so that when it is attached to the keycap 11, its elasticity is relatively greater and can better Adapt to the size of the keycaps. Specifically, the thickness is 0.03mm in this embodiment. This setting makes the thickness of the main waterproof layer 20 moderate, which can improve its flexibility so that it can fit easily with the keycap 11. Materials with higher flexibility can better adapt to the keycap. 11 is pulled when pressed, reducing the impact of the waterproof layer on the feel of the keycap 11 when pressed. The thinner the flexible material, the higher the processing difficulty and the corresponding higher processing and production costs. The thicker the flexible material, the lower the processing difficulty and the higher the material cost. Therefore, a moderate thickness selection can balance the processing difficulty and production cost.

As shown in Figures 8, 9 and 11, in the technical solution of the second embodiment, the support assembly 40 also includes a buffer structure 43. The buffer structure 43 is provided between the main waterproof layer 20 and the support layer 42. The buffer structure 43 includes The first limiting portion 431 can surround the first supporting structure 41 , and the buffering structure 43 is in contact with the supporting layer 42 .

The first support structure 41 is used The hard material has a certain weight and high hardness, which can ensure the structural fixation of the second fitting portion 32 of the main waterproof layer 20 to facilitate subsequent assembly with the keycap 11 . The bottom waterproof layer 60 is used to waterproof the bottom of the keyboard as a whole, and fits with the main waterproof layer 20 to wrap the keyboard as a whole. This arrangement makes the keyboard a whole, and the upper surface of the keyboard is waterproof and dustproof through the main waterproof layer 20. The bottom is waterproof and dustproof through the bottom waterproof layer 60 , and the sides are waterproof and dustproof through the combination of the bottom waterproof layer 60 and the main waterproof layer 20 . Specifically, an adhesive can be provided between the bottom waterproof layer 60 and the main waterproof layer 20 , or the two can be integrated into one through hot pressing, which can enhance the waterproof performance of the keyboard.

The flexible material has a certain ability of elastic deformation to adapt to the work of the keycap 11 . The bottom waterproof layer 60 is made of waterproof leather, textile or nano fabric material. Such materials have a higher texture and better touch, making it more comfortable when transferring the keyboard. The first support structure 41 is made of hard materials such as PC, PET, PI, LCP or FR4. Specifically, PC material is used because the flexible material is not hard enough and is prone to deformation during assembly and pressing. Therefore, a hard first support material is used to support the flexible main waterproof layer. On the one hand, such an arrangement can give the first support structure 41 a certain hardness and weight to achieve the effect of stretching the second fitting portion 32 downward; On the one hand, the above-mentioned material has a certain elastic deformation ability and can better adapt to the ability to cope with the deformation of the main waterproof layer 20 when the keycap 11 is pressed down.

There will also be related phenomena, which will greatly affect the user's actual experience and even affect the user's consideration of using a waterproof keyboard again. Furthermore, when the waterproof layer is made of a thicker material, providing the first support structure 41 can form certain constraints on the thicker material that is not easy to form to a certain extent, so that the waterproof layer can effectively fit with the keycap 11 , however, due to the low degree of deformation of thicker materials, there is a high probability that unformed parts will appear during molding, which in turn makes the setting of the first support structure 41 easy to affect the waterproof layers of the keycaps 11 on both sides. Under the force of the support structure 41, a related reaction occurs. Although the problem of fit between the waterproof layer and the keycap 11 can be solved to a certain extent, the related problem cannot be completely solved. The use of a thinner waterproof layer and the setting of the first support structure 41 can avoid the problem of difficult molding. At the same time, after the assembly is completed, the keycap 11 can better adapt to the deformation of the waterproof layer when pressed, and the deformation of the waterproof layer does not occur. The first support structure 41 will not be driven to affect the waterproof layer of the adjacent keycap 11, and the waterproof layer will not be involved.
