Obviously, the described embodiments These are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present invention.

As shown in Figures 1 to 3, Embodiment 1 of the present invention provides a keyboard, including: a top waterproof layer 10, a keycap 20, and a support assembly 30. The top waterproof layer 10 includes a first fitting portion 11, a second fitting portion part 12 and the third fitting part 13; the keycap 20 includes a pressing surface 21, a first through hole 22 and a keycap side wall 23.

The first support structure 31 Fitted with the third fitting part 13, an accommodation gap 40 is set between the first support structure 31 and the vertical plane where the bottom side of the adjacent keycap 20 is located. When the keycap 20 is pressed, the deformation area of the top waterproof layer 10 is located within the accommodation gap 40. The first laminating part 11 , the second laminating part 12 and the third laminating part 13 can completely cover the keyboard for waterproof purposes. The first through hole 22 is provided to facilitate the connection between the pressing surface 21 and the first laminating part 11 The air in the space is discharged, so that the connection between the pressing surface 21 and the first fitting part 11 can be closer. The accommodating gap 40 can accommodate the deformation area of the top waterproof layer 10 when the keycap 20 is pressed, avoiding the deformation of the top waterproof layer 10 The top waterproof layer 10 that affects the adjacent keycaps 20 and is deformed at the same time can be stored, avoiding affecting the pressing feel of the keycaps 20 and improving the keyboard usage experience. Moreover, the setting position of the top waterproof layer 10 is both before and after the keycap 20 is pressed. The fixed position avoids the failure of the top waterproof layer 10 due to deformation and failure to return to the original position, and improves the service life of the keyboard. The invention effectively solves the problem in the prior art that the deformation of the waterproof layer of the keyboard affects the pressing feel of the keyboard. It should be noted that there are multiple keycaps 20 in order to cope with the use of the keyboard. Figures 1 and 2 are only assembly diagrams of a single keycap 20. An elastic member is provided under the keycap 20 so that the keycap 20 can be Rebound. It should be noted that the uppermost end of the accommodating gap 40 is the bonding surface between the third bonding portion 13 and the first support structure 31 . In this embodiment, fitting means that the two fitting parts may be in contact with each other, but it is not limited to whether the two fitting parts are fixedly connected. After the assembly is completed, the two fitting parts are compact in structure and less likely to generate bubbles.

As shown in Figures 1 to 3, in the technical solution of Embodiment 1, the deformation area is the deformation part 14 of the top waterproof layer 10, and the deformation part 14 is connected to the second fitting part 12 and the third fitting part 13 respectively. When the keycap 20 is pressed, the deformation portion 14 can be completely accommodated in the accommodation gap 40 . The deformation part 14 is provided for the deformation of the top waterproof layer 10 when pressed. The purpose of this arrangement is to control the deformation of the top waterproof layer 10 within the deformation part 14, and at the same time, it can avoid the second fitting part 12 from contacting the side wall of the keycap. 23 is pulled, causing the second fitting portion 12 to fall off from the keycap side wall 23 .

As shown in FIGS. 1 to 3 , in the technical solution of Embodiment 1, the deformation part 14 includes a bending section 141 and a bending section 142 , and the bending section 141 is provided between the bending section 142 and the second fitting part 12 . The bending section 142 is connected to the third fitting portion 13 . Furthermore, the deformation part 14 is divided into a bending section 141 and a bending section 142. The deformation amount of the deformation part 14 close to the second fitting part 12 is larger, and the deformation position changes more, so the bending section 141 can adapt to larger range of deformation, and at the same time, the bending section 142 is arranged to be connected with the third fitting part 13. In order to play a certain supporting and connecting role and prevent the deformation part 14 from driving the third fitting part 13 to fall off, the bending section 142 is provided to allow the deformation. The third bonding part 13 is far away in the area and will not affect the bonding of the third bonding part 13 .

As shown in FIGS. 1 to 3 , in the technical solution of Embodiment 1, the bending section 142 can rotate around the connection point 131 between the bending section 142 and the third bonding portion 13 . The connection point 131 and the bending section 142 are provided to rotate around the connection point 131 between the bending section 142 and the third fitting part 13 so that the bending section 142 changes the positional relationship with the third fitting part 13 through rotation, thereby avoiding stretching. The deformation causes the third fitting portion 13 to be subjected to a tensile force, causing the third fitting portion 13 to fall off.

As shown in FIGS. 1 to 3 , in the technical solution of Embodiment 1, the connection point 131 is provided at a position where the third fitting portion 13 extends in a direction close to the keycap. The connection point 131 is set away from the first support structure 31 so that the bending section 142 can rotate at a large angle. This arrangement allows the bending section 141 to be located in the accommodation gap 40 when the keycap 20 is pressed, and to be stretched. The state prevents the curved section 141 from always being in a deformed and compressed state, and can prevent the curved section 141 from being deformed for a long time, resulting in the failure of the curved section 141, thereby improving the long-term use of the top waterproof layer 10 material.

As shown in FIGS. 1 to 3 , in the technical solution of Embodiment 1, when the keycap 20 is not pressed, the deformation portion 14 is located outside the accommodation gap 40 . Such an arrangement allows the deformation part 14 to be completely located above the accommodation gap 40, making the deformation part 14 invisible to the accommodation gap 40 when the keycap 20 is not pressed, and improving the overall visual appearance of the keyboard. In terms of waterproof performance, water accumulation at the accommodation gap 40 is avoided.

As shown in FIGS. 1 to 3 , in the technical solution of Embodiment 1, when the keycap 20 is not pressed, the bending section 142 and the third fitting portion 13 are located in the same plane, and the bending section 141 is arc-shaped. 141 is located on the side of the plane close to the keycap 20 . The curved section 141 arranged in an arc makes the top waterproof layer 10 of the keyboard integrated when viewed from top to bottom, avoiding the appearance of ravine lines and conducive to the formation of lumps when designing the appearance. The bending section 142 and the third fitting portion 13 are located in the same plane. This arrangement can also hide the connection points, making the overall presentation effect obvious and reducing the amount of material required. On the premise that the waterproof performance of the above keyboard is stable, the structure of the keyboard does not need to be more stable.

It should be noted that in the technical solution of Embodiment 1, the top waterproof layer 10 needs to be pre-pressed into the shape of the keycap 20 before assembly, as shown in Figure 3. After the assembly is completed, the top waterproof layer 10 formed is The assembly effect of the keycap 20 is shown in Figures 2 and 3. When the keycap 20 is not pressed, the keycap 20 lifts up the waterproof layer around the entire keycap 20 , thereby hiding the accommodation gap 40 of the keycap 20 under normal conditions, further enhancing the appearance effect. When the keycap is pressed, the deformation portion 14 can be completely accommodated in the accommodation gap 40 . The deformation part 14 not only provides the stretching length of the waterproof layer required for pressing the keycap 20, but also simultaneously guides the waterproof layer of the keycap side wall 23 downward, thereby maintaining the integrity of the appearance; the initial molding deformation is designed The depth of the part 14 is shallow, and the waterproof layer has downward resilience before the keycap 20 is pressed, so that the waterproof layer can still be close to the keycap 20 during a quick pressing operation, further enhancing the appearance of the product during operation. effect and improve the pressing feel of the keyboard.

It should be noted that, as shown in FIGS. 4 and 5 , the technical solution of the second embodiment is different from the technical solution of the first embodiment in that the connection point 131 of the second embodiment is disposed on the first support structure 31 At the corners, such an arrangement can further reduce the length of the bending section 142 and reduce the material of the top waterproof layer 10 . When the top waterproof layer 10 uses softer materials, such an arrangement is more conducive to the formation of the top waterproof layer 10 . The top waterproof layer 10 in the present invention is an integrally formed structure. The advantage of such an arrangement is strong waterproof performance. At the same time, it can avoid the structural complexity of the keyboard due to the waterproof design, and is also conducive to reducing the overall thickness of the keyboard.

As shown in FIGS. 6 to 8 , in the technical solution of the third embodiment, when the keycap 20 is not pressed, at least part of the deformation portion 14 is located within the accommodation gap 40 . The difference between the third embodiment and the first embodiment is that the top waterproof layer 10 is provided with an extra deformation part 14, that is, the bending section 141 and the bending section 142 are lengthened to a certain extent. This arrangement can completely avoid the second fitting part 12 and The third fitting portion 13 falls off, which can effectively increase the service life of the top waterproof layer 10 .

As shown in FIGS. 6 to 8 , in the technical solution of the third embodiment, when the keycap 20 is not pressed, the second fitting portion 12 is completely fitted to the keycap side wall 23 . Furthermore, the second fitting part 12 can be completely fitted with the keycap side wall 23 , increasing the degree of integration between the two as much as possible, thus better preventing the second fitting part 12 from being removed from the keycap side wall 23 fall off. It should be noted that the technical solution of the third embodiment is to arrange the connection point 131 outside the third fitting part 13. Such an arrangement enables the curved section 141 to be located in the accommodation gap 40 when the keycap 20 is pressed, and can obtain The stretched state prevents the curved section 141 from always being deformed and compressed, and can prevent the curved section 141 from being deformed for a long time, which would lead to the failure of the curved section 141, thereby improving the long-term use of the top waterproof layer 10 material. It should be noted that in the technical solution of Embodiment 3, the top waterproof layer 10 needs to be pre-pressed into the shape of the keycap 20 before assembly. As shown in FIG. 8 , after the assembly is completed, the top waterproof layer 10 and The assembly effect of the keycap 20 is shown in Figures 6 and 7. When the keycap 20 is not pressed, the top waterproof layer 10 assembly only rests on the keycap 20 without any other interaction force. The deformation portion 14 not only provides the stretching length of the top waterproof layer 10 required for pressing the keycap 20, but also simultaneously guides the waterproof layer of the keycap side wall 23 downward, thereby maintaining the integrity of the appearance.

It should be noted that the present invention also provides Embodiment 4 and Embodiment 5. As shown in FIGS. 9 and 10 , in the technical solution of Embodiment 4, when the keycap 20 is not pressed down, the deformation part 14 is The curved section 141 is provided under the keycap 20. This arrangement further increases the length of the deformation portion 14 to ensure that the fit of each part is not affected by pulling, which is beneficial to increasing the actual service life of the keyboard itself.

As shown in Figures 11 and 12, in the technical solution of Embodiment 5, the difference between Embodiment 5 and Embodiment 3 is that the location of the connection point 131 is the same as that in Embodiment 2. In this way, the bending section 141 and the bending section are arranged 142 is lengthened to a certain extent. This arrangement can completely prevent the second laminating part 12 and the third laminating part 13 from falling off, and can also reduce the use of materials to a certain extent and reduce production costs.

As shown in Figures 13 to 15, in the technical solution of Embodiment 6 provided by the present invention, the keyboard in Embodiment 6 is further improved based on the technical solutions in Embodiment 1 to Embodiment 5, and the keyboard also includes adhesive tape. The adhesive layer 50 is disposed between the pressing surface 21 and the first laminating part 11. The adhesive layer 50 is bonded to the pressing surface 21 and the first laminating part 11 respectively. There are a plurality of first through holes 22. , the central axis of each first through hole 22 is arranged in a direction perpendicular to the pressing surface 21 . Such an arrangement ensures that the angular relationship between the side wall of the first through hole 22 and the pressing surface 21 is constant, the adhesive layer 50 and the first through hole 22 cooperate evenly, and the angle formed by the side wall of the first through hole 22 and the pressing surface is equal. , will not cause the risk of puncture to the adhesive layer 50, and at the same time make the adhesive layer 50 better adhered.

It should be noted that in the technical solution of Embodiment 6, the pressing surface 21 can be a flat surface, which is suitable for thin and light keyboards. The pressing surface 21 can also adapt to the arc surface of the fingers, and is suitable for thicker keycaps 20. The arc surface The purpose of setting is to improve the tactile feeling when the keycap 20 comes into contact with fingers. This setting results in a certain gap between the keycap 20 and the top waterproof layer 10, which may easily lead to insufficient adhesion of the waterproof layer, causing the waterproof layer and the keycap to There are air bubbles between the keycaps 20 , which seriously affects the user experience when the keycaps 20 are pressed. The top waterproof layer 10 adopts an integrated structure to cover the entire keycap area, so as to achieve the best waterproof performance. This setting can reduce the waterproof and dustproof treatment required inside the keyboard, simplifying the internal structure and making it more conducive to production. The top waterproof layer 10 is made of a certain flexible material. Specifically, the materials include PU, TPU, TPE, LSR, Silicone, Rubber and other flexible materials; the adhesive layer 50 can use double-sided tape as the connecting material, which is simple and easy to obtain. , convenient for production and processing.

As shown in FIG. 14 , in the technical solution of Embodiment 6, the cross section of the first through hole 22 is circular, and the maximum size of the cross section of the first through hole 22 is 0.05 to 0.2 mm. The circular arrangement of the first through hole 22 further reduces the risk of the adhesive layer 50 being punctured. At the same time, the circular through hole is easy to process, and the structural strength of the circular through hole is higher than that of other shapes. higher. The aperture is 0.05 to 0.2mm, which is used for exhaust at 21 places where the adhesive layer 50 is attached to the contact pressing surface to improve the attachment yield; at the same time, the small aperture of the micro through hole will not leave any trace on the appearance; through hole It can be realized through post-process CNC, laser, electric discharge and other processing, or mold forming.

As shown in FIG. 15 , in the technical solution of Embodiment 6, the hole wall of the first through hole 22 is arranged in a straight line along the direction of the central axis. Such an arrangement makes it easier for the processing of the first through hole 22 to start from the pressing surface 21 or end from the pressing surface 21, which can reduce the processing requirements of the first through hole 22. Such an arrangement is more compact and can reduce the need for material removal. This reduces the overall structural strength of the keycap 20 and leads to the risk of damage.

As shown in FIG. 16 , in another optional embodiment, in the direction of the first through hole 22 on the keycap 20 away from the central axis of the pressing surface, the hole wall of the first through hole 22 gradually moves away from the central axis. Such an arrangement allows the first through hole 22 to remove more material and reduce the overall weight; at the same time, it can increase faster exhaustion when the adhesive layer 50 is applied. In addition, when the adhesive layer 50 is liquid glue, the glue entering the first through hole 22 will form a conical solid after solidification. Since the diameter of the hole on the pressing surface 21 is small, the formed solid cannot pass through, so that the solid will be formed. The adhesive layer 50 and the keycap 20 are integrated and cannot be separated. This arrangement effectively increases the service life of the keycap. It should be noted that the first through hole 22 can be realized through post-process CNC, laser, electric discharge and other processing, or mold forming. It should be noted that part of the first through hole 22 can have the hole wall arranged in a straight line along the direction of the central axis, and part of the first through hole 22 can have the hole wall gradually arranged away from the central axis. Through the combination, it is possible to realize the entry of liquid glue to form a limit, and also to realize The role of exhaust.

On the basis of the above embodiments, further improvements have been made in Embodiment 6 of the present invention. The keycap 20 further includes a limiting portion 24. The limiting portion 24 surrounds the pressing surface 21. The limiting portion 24 forms an adhesive bond with the pressing surface 21. The receiving cavity of the connecting layer 50. Such an arrangement allows the adhesive layer 50 to be limited within a certain range, which facilitates assembly; at the same time, the arrangement of the limiting portion 24 can support the area of the pressing surface 21 to obtain the top waterproof layer 10. This arrangement can avoid the problem of the adhesive layer 50 being damaged. The uneven thickness causes the first bonding portion 11 to be uneven after the top waterproof layer 10 is bonded. Furthermore, in order to increase the flatness of the first bonding part 11 and the connection effect between the adhesive layer 50 and the first bonding part 11 , liquid glue can also be filled around the adhesive layer 50 , and the liquid glue solidifies to make the bonding The layer 50 is integrated with the keycap 20 and will not form defects such as bubbles with the first laminating part 11 when bonded to the first laminating part 11. This arrangement can also reduce the processing accuracy of the adhesive layer 50, and further Suitable for production.

In the technical solution of Embodiment 6, the adhesive layer 50 may be a sheet-shaped adhesive, and the adhesive layer 50 is adhered to the first bonding part 11 and the pressing surface 21 respectively. The sheet-shaped adhesive of the adhesive layer forms a general arc shape to correspond to the arrangement of the keycap 20 , and the sheet-shaped adhesive is more suitable for installation in the limiting portion 24 . The sheet-like adhesive is generally in the shape of a sheet, and may specifically be a double-sided adhesive layer, capable of directly bonding the first bonding part 11 and the pressing surface 21 . When the keycap 20 is in an arc shape in accordance with finger pressing, the pressing surface 21 can be pressed closely to the pressing surface 21 to improve the pressing feel. It should be noted that the thickness of the double-sided adhesive layer is selected to be the same as the depth of the accommodation cavity formed by the limiting portion 24, so that better adhesion can be achieved. Liquid glue can also be used for the adhesive layer 50 , and part of the liquid glue enters the first through hole 22 . Specifically, the liquid glue can use glue with a large viscous resistance, so that the glue can partially enter the first through hole 22 and completely solidify before passing through the first through hole 22 to form a cylinder. The cylinder and the first through hole 22 The side walls are fixedly connected, which can increase the connection effect of the adhesive layer 50 so that the entire adhesive layer 50 is completely fixed to the keycap 20 . It should be noted that the adhesive layer 50 can be bonded using a variety of adhesives. For example, a combination of liquid glue and a sheet-like adhesive can achieve a reliable bonding effect and exhaust effect.

In the sixth embodiment described above, the keycap 20 further includes a second through hole, and the top waterproof layer 10 further includes a second fitting portion 12 . The second through hole is provided on the keycap side wall 23 of the keycap 20 . The joint portion 12 and the keycap side wall 23 are bonded by liquid glue, and part of the liquid glue enters the second through hole. The second through hole provided on the side wall of the key cap 23 is beneficial to the adhesion between the second fitting part 12 and the side wall of the key cap 20 , and the liquid glue as the bonding substance can completely fix the entire adhesive layer 50 on the key cap 20 At the same time, the first through hole 22 and the second through hole are arranged in different directions, so that there is a staggered structural force between the adhesive layer 50 and the keycap 20, which can effectively prevent the adhesive layer 50 from falling off the keycap 20. , thereby improving the actual service life of the adhesive layer 50 .

As shown in Figures 17 and 18, the technical solution of Embodiment 7 of the present invention provides an electronic device. The electronic device includes a keyboard and a device body. The keyboard is the keyboard of any one of Embodiments 1 to 6. The keyboard Signal connection with the main body of the device. The keyboard arranged in this way can ensure the appearance integrity of the waterproof layer fitting the keycap, and the first through hole 22 is processed on the keycap 20 to ensure the exhaust function when the first fitting part 11 is fitted with the pressing surface 21. At the same time, the micropores have extremely small diameters, and there are no traces on the appearance. The signal connection between the keyboard and the main body of the device. The electronic device can be a notebook computer, a tablet device or other electronic devices. The signal connection is such that the above-mentioned keyboard can serve the electronic device to realize the function of the keyboard. The keyboard is easy to carry and transfer, and has good waterproof and dustproof capabilities. Suitable for harsh environments and able to cope with diverse living environments. It should be noted that the signal connection method can be a wireless signal connection, such as Bluetooth and other wireless signal connection means, which is more convenient. You can also set up a wired connection to interactively transmit signals through data lines, making data transmission more stable and convenient.

It should be noted that in the technical solution of Embodiment 7, the keyboard also includes a second support structure 32, a touch module 60, a bottom mounting plate 70 and a bottom waterproof layer 80. The keycap 20 is provided on the keyboard module. The module and the touch module 60 are jointly arranged on the bottom mounting plate 70; the second support structure 32 is arranged between the top waterproof layer 10 and the first support structure 31, because the top waterproof layer 10 is to increase the resistance of the keycap 20 when it is pressed. The feel is that the whole body is made of flexible materials. The thinner top waterproof layer 10 is highly elastic and easy to deform. The second support structure 32 is provided for buffering, so as to facilitate the support function of the top waterproof layer 10 and at the same time provide a certain hardness so that The top waterproof layer 10 can be better stretched to achieve a beautiful effect. The setting of the touch module 60 facilitates the electronic device to have the function of a mouse, and the electronic device can have more functions through the keyboard. When the keyboard is used as an external keyboard for a notebook computer, the touch module 60 can be used to replicate the notebook The computer's touchpad prevents the laptop from overheating and affecting the keyboard's operating feel, thereby increasing the keyboard's practicality. When the keyboard is used as an external keyboard for a tablet computer, the usage functions of the tablet computer can be increased. Most existing tablet computers can be installed with Microsoft computer operating systems. The touch module 60 can be configured to adapt to the above computer operating systems and turn the tablet computer into a notebook type. For computer use, such a setting allows the electronic device to have more functions and more space for operation. Due to the provision of the touch module 60, the keyboard forms a hand rest between the keycap area and the touch module 60. The hand rest can support the base of the palm when using the keyboard and can support the hand. At the same time, it reduces the pressure of the hand on the keycap area, thereby extending the service life of the keyboard. The keyboard also includes a bottom waterproof layer 80 , which wraps the keyboard. The bottom waterproof layer 80 is bonded with the top waterproof layer 10 . The top waterproof layer 10 is made of flexible materials. Specifically, the materials include PU, TPU, TPE, and LSR. , Silicone, Rubber and other flexible materials. The thickness of the top waterproof layer 10 ranges from 0.01mm to 0.2mm. Such a thickness can ensure precise structure during the molding process, so as to facilitate subsequent better assembly of the keyboard.
