[0002] A computer keyboard is a device used to input instructions and data to operate computer equipment. It is the most commonly used input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc., can be input into the computer, thereby issuing commands and inputting data.

[0003] A standard keyboard consists of a support frame and keyboard components housed within it. These components include a circuit board, keyboard switches, and several keys. Users input commands into the computer by pressing the corresponding keys. As keyboards have evolved, they have evolved to meet different usage requirements in various scenarios. For example, in office settings, keyboards are used daily with rapid keystrokes, necessitating both extended lifespan and noise reduction. However, conventional keyboards generate significant vibration and noise from the interaction of their various components during keystrokes, making it difficult to meet these noise reduction requirements. Utility Model Content

[0004] The purpose of this application is to provide a keyboard structure that aims to improve the problem of excessive vibration noise emitted by keyboards when typing in related technologies, and to meet the noise reduction requirements.

[0005] This application provides a keyboard structure, including a keyboard assembly. The keyboard assembly includes an outer support frame, an inner support frame fitted into the outer support frame, a keyboard component disposed in the inner support frame, and a noise-absorbing component. The noise-absorbing component includes a plurality of foam layers disposed between the keyboard component and the outer support frame, and a noise-absorbing adhesive layer disposed between the outer support frame and the inner support frame. The plurality of foam layers are sequentially disposed along the height of the outer support frame. The noise-absorbing adhesive layer is located on one side of the plurality of foam layers and is also located between the keyboard component and the outer support frame.

[0006] Furthermore, an installation groove is provided between the outer support frame and the inner support frame, and the installation groove extends along the inner wall of the edge of the outer support frame; the sound-absorbing adhesive layer is disposed in the installation groove and extends along the length of the installation groove.

[0007] Furthermore, the sound-absorbing adhesive layer includes an upper adhesive portion and a lower adhesive portion connected in sequence, and there is a cavity between the upper adhesive portion and the lower adhesive portion for cooperating with the keyboard component. The cavity is located on one side of the keyboard component and faces the keyboard component.

[0008] Furthermore, the sound-absorbing adhesive layer also includes a support portion, which is located between the upper adhesive portion and the lower adhesive portion, and the upper adhesive portion and the lower adhesive portion abut against the support portion.

[0009] Furthermore, the keyboard component includes a support plate, a circuit board, a keyboard switch, and keyboard keys disposed in the inner support frame; the cavity faces the support plate, and the support plate abuts against the upper adhesive part and the lower adhesive part.

[0010] Furthermore, it also includes a support assembly, which includes a lower support cover disposed on the outer support frame. The lower support cover is disposed below the outer support frame and has a plurality of support pads disposed circumferentially along the edge of the outer support frame.

[0011] Furthermore, it also includes a telescopic assembly, which includes a support base disposed on the lower support cover, a guide slide disposed on the support base, and a push rod slidably connected to the guide slide; the support base has a lower hinge block, which is hinged to the lower support cover; the guide slide has a guide hole; the push rod includes a rod body slidably connected to the guide hole, the rod body abutting against the guide hole, and the rod body has an upper hinge block, which is hinged to the keyboard assembly.

[0012] Furthermore, the outer support frame has an upper adapter groove on its side for fitting and installing the telescopic component, and one end of the telescopic component is fitted into the upper adapter groove; the upper adapter groove is divided into an upper mounting groove and an upper main body cavity, the support seat and the guide slide seat are fitted into the upper main body cavity, and the upper hinge block is fitted into and rotatably connected to the upper mounting groove.

[0013] The beneficial effects of this application are:

[0014] 1. A keyboard structure according to this application, by setting a noise-absorbing component and utilizing several foam layers disposed between the keyboard component and the outer support frame, when the keyboard component is pressed by the operator, the keyboard component can avoid direct contact with the outer support frame in the direction of keyboard height. The vibration generated by the keyboard component will be absorbed and buffered by the several foam layers, thereby reducing the noise generated by the keyboard component contacting the outer support frame. On the other hand, the noise-absorbing adhesive layer can fill the gap between the outer support frame and the inner support frame, thereby reducing the contact area between the outer support frame and the inner support frame and reducing the collision noise between the outer support frame and the inner support frame. On the other hand, the noise-absorbing adhesive layer located between the keyboard component and the outer support frame can prevent the keyboard component from directly contacting the outer support frame in the width direction of the keyboard, further reducing the noise generated by the keyboard component contacting the outer support frame, thereby effectively reducing the noise during keyboard typing and meeting the noise reduction requirements.

[0015] 2. In a keyboard structure of this application, the sound-absorbing adhesive layer is laid and extended along the mounting groove, so that the sound-absorbing adhesive layer can cover and fill the gap between the outer support frame and the inner support frame to achieve a better sound-absorbing effect; at the same time, the sound-absorbing adhesive layer is set as an upper adhesive part and a lower adhesive part with a cavity, and a support part is set in the cavity. The cavity can cooperate with the keyboard component to avoid interference between the keyboard component and the sound-absorbing adhesive layer. On the other hand, the cavity can reduce the material cost of the sound-absorbing component while ensuring the sound-absorbing effect, making the keyboard structure easier to manufacture.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0028] Reference Figure 1 as well as Figure 2 This application provides a keyboard structure, including a keyboard assembly 1. The keyboard assembly 1 includes an outer support frame 11, an inner support frame 12 fitted and mounted on the outer support frame 11, a keyboard component 13 disposed on the inner support frame 12, and a noise-reducing component 14. Specifically, the outer support frame 11 serves as the external frame of the keyboard structure for supporting and mounting the inner support frame 12. The outer support frame 11 has an outer wall and an inner wall, with the inner wall forming a cavity. The inner support frame 12 is disposed in the cavity and abuts against the inner wall of the outer support frame 11. The inner support frame 12 is used to mount and limit the keyboard component 13. The keyboard component 13 includes a support plate 131 disposed on the inner support frame 12, a circuit board, a keyboard switch, and keyboard keys. The keyboard component 13 is prior art and can be purchased; its specific structure and working principle will not be described in detail.

[0029] Reference Figure 2 as well as Figure 3The noise-reducing component 14 is used to reduce the noise emitted by the keyboard assembly 1 when it is typed. The noise-reducing component 14 includes several foam layers disposed between the keyboard assembly 13 and the outer support frame 11, and a noise-reducing adhesive layer 143 disposed between the outer support frame 11 and the inner support frame 12. In this embodiment, for ease of description, the side of the keyboard that is supported on the desktop is designated as the bottom, the side of the keyboard keys facing is designated as the top, the right side of the keyboard in the width direction when in use is designated as the right side, and the left side of the keyboard in the width direction when in use is designated as the left side. Specifically, the several foam layers are arranged sequentially along the height of the outer support frame 11. In this embodiment, there are two foam layers, namely a first foam layer 141 and a second foam layer 142. The first foam layer 141 and the second foam layer 142 are arranged sequentially along the height direction of the keyboard and are located below the support plate 131. By setting the first foam layer 141 and the second foam layer 142, when the operator uses the keyboard structure, the support plate 131 contacts the foam layer, thereby preventing the keyboard component 13 from directly contacting the outer support frame 11 in the direction of keyboard height. The vibration generated by the keyboard component 13 will be absorbed and buffered by the foam layer, thereby reducing the noise generated by the keyboard component 13 contacting the outer support frame 11.

[0030] The sound-absorbing adhesive layer 143 is located on one side of several foam layers, and is also located between the keyboard component 13 and the outer support frame 11. In this embodiment, there is a mounting groove between the outer support frame 11 and the inner support frame 12, and the mounting groove extends along the inner wall of the edge of the outer support frame 11; the sound-absorbing adhesive layer 143 is disposed in the mounting groove and extends along the length direction of the mounting groove. It can be understood that the length of the sound-absorbing adhesive layer 143 extending along the length direction of the mounting groove can be adjusted according to actual needs.

[0031] It is worth mentioning that, considering the cost of the sound-absorbing adhesive layer 143 and its fit with the keyboard component 13, the sound-absorbing adhesive layer 143 includes an upper adhesive portion 1431 and a lower adhesive portion 1432 connected in sequence. A cavity for fitting the keyboard component 13 is provided between the upper adhesive portion 1431 and the lower adhesive portion 1432. The cavity is located on one side of the keyboard component 13 and faces it. In this embodiment, the cavity faces the support plate 131, and the support plate 131 abuts against the upper adhesive portion 1431 and the lower adhesive portion 1432. Simultaneously, the sound-absorbing adhesive layer 143 also includes a support portion 1433, located between the upper adhesive portion 1431 and the lower adhesive portion 1432. The support portion 1433 can specifically be a rigid plastic or stainless steel sheet. The upper adhesive portion 1431 and the lower adhesive portion 1432 abut against the support portion 1433, meaning the support portion 1433 separates and supports the upper adhesive portion 1431 and the lower adhesive portion 1432. With this design, the sound-absorbing adhesive layer 143 can cover and fill the gap between the outer support frame 11 and the inner support frame 12 to achieve a better sound-absorbing effect. Simultaneously, the cavity can cooperate with the support portion 1433 of the keyboard component 13, preventing interference between the support portion 1433 and the sound-absorbing adhesive layer 143. During vibration, the support portion 1433 directly acts on the sound-absorbing adhesive layer 143, ensuring the sound-absorbing effect. The cavity design also reduces the material cost of the sound-absorbing component 14, as only the support portion 1433 is needed to support the upper adhesive portion 1431 and the lower adhesive portion 1432, making the keyboard structure easier to manufacture. It should be noted that the cavity between the upper adhesive portion 1431 and the lower adhesive portion 1432 can also be filled with the same material, making the upper adhesive portion 1431 and the lower adhesive portion 1432 a solid, integrated structure, eliminating the need for the support portion 1433.

[0032] Reference Figure 4 as well as Figure 5In addition, the keyboard structure also includes a support component 2 and a telescopic component 3. The support component 2 includes a lower support cover 21 disposed on the outer support frame 11. The lower support cover 21 is disposed below the outer support frame 11 and has a plurality of support pads disposed circumferentially along the edge of the outer support frame 11. The telescopic component 3 is used to adjust the height of the keyboard component 1 to suit the usage needs of different operators. There are two telescopic components 3, which are located on both sides of the lower support cover 21 and connected to the outer support frame 11 respectively. Taking a single telescopic component 3 as an example, the telescopic component 3 includes a support base 31 set on the lower support cover 21, a guide slide 32 set on the support base 31, and a push rod 33 slidably connected to the guide slide 32. The support base 31 has a lower hinge block 311, which is hinged to the lower support cover 21. The guide slide 32 has a guide hole 321. The push rod 33 includes a rod body 331 slidably connected to the guide hole 321, which abuts against the guide hole 321. The rod body 331 has an upper hinge block 332, which is hinged to the outer support frame 11 of the keyboard component 1.

[0033] The support base 31 provides support for the guide slide 32 and the push rod 33. The support base 31 is cylindrical and has an internal cavity to accommodate the installation of the guide slide 32 and the push rod 33. The end of the support base 31 near the lower support cover 21 has a lower hinge block 311, which is hinged to the lower support cover 21 of the support assembly 2. The guide slide 32 is installed at the end of the support base 31 near the outer support frame 11. Specifically, the guide slide 32 can be installed on the support base 31 via a threaded connection. The guide slide 32 has a guide hole 321 for engaging the push rod 33, and the shape of the guide hole 321 matches the shape of the push rod 33. The push rod 33 includes a rod body 331 that slidably connects to the guide hole 321. The rod body 331 abuts against the guide hole 321. The rod body 331 has an upper hinge block 332, which is hinged to the upper support assembly 2. Since different keyboards have different weights and sizes, the size and shape of the push rod 33 will also change. In order to better adapt to different push rods 33, the guide slide 32 is provided with a locking block 322 for cooperating with the push rod 33. The locking block 322 is detachably connected to the side of the guide slide 32 near the upper support component 2, and the guide hole 321 is located in the locking block 322.

[0034] In this embodiment, the guide slide 32 has several limiting grooves on the side near the upper support component 2. These limiting grooves are evenly arranged along the edge of the guide slide 32. The locking block 322 has corresponding protrusions. The number of limiting grooves and protrusions are the same and correspond one-to-one. The protrusions are fitted into the limiting grooves. With this configuration, when the diameter or shape of the push rod 33 changes, it can be quickly adapted by simply replacing the guide slide 32 with the corresponding guide hole 321, without having to redesign and manufacture the entire telescopic component 3.

[0035] In addition, the telescopic assembly 3 also includes a telescopic drive member 34 for driving the push rod 33. The telescopic drive member 34 is disposed on the support base 31 and faces the push rod 33. The end of the push rod 33 away from the upper support assembly 2 is connected to the telescopic drive member 34. In this embodiment, the telescopic drive member 34 is an electric cylinder. The telescopic drive member 34 is installed and fixed in the cavity of the support base 31, and the piston end of the telescopic drive member 34 is connected to the push rod 33.

[0036] In this embodiment, to avoid the telescopic component 3 protruding and occupying space other than the keyboard, the outer support frame 11 has an upper adapter groove 111 on its side for fitting and installing the telescopic component 3. One end of the telescopic component 3 is fitted into the upper adapter groove 111. The upper adapter groove 111 is divided into an upper mounting groove 1111 and an upper main body cavity 1112. The support base 31 and the guide slide 32 are fitted into the upper main body cavity 1112, and the upper hinge block 332 is fitted into and rotatably connected to the upper mounting groove 1111. Correspondingly, the lower support cover 21 has a lower adapter groove, which is divided into a lower mounting groove and a lower main body cavity. The support base 31 is fitted into the lower main body cavity, and the lower hinge block 311 is fitted into and rotatably connected to the lower mounting groove. With this configuration, the telescopic component 3 is fitted into the lower support cover 21 in a fitting manner, which can prevent the telescopic component 3 from protruding from the lower support cover 21 and occupying additional space outside the keyboard. At the same time, it can protect the telescopic component 3 and prevent it from failing due to external collisions, thereby increasing the stability and service life of the keyboard support structure.

[0037] Reference Figure 6 as well as Figure 7 During adjustment, the telescopic drive component 34 is activated, and the piston-end drive push rod 33 extends from the guide slide 32. The extended push rod 33 lifts the upper support component 2, causing the upper support component 2 and the lower support component 2 to form an angle. Since the stroke of the piston end can be adjusted within a range, the keyboard can be adjusted at multiple angles within that range. It should be noted that the telescopic drive component 34 can also be a cylinder. It is understood that the telescopic component 3 does not depend on the telescopic drive component 34 for operation. In some embodiments, the guide slide hole 321 can be fitted with the rod body 331 by interference fit or damping connection. Even without the telescopic drive component 34, the rod body 331 can still be fixed by extending at different lengths within the guide slide hole 321, thereby enabling a wide range of angle adjustments.
