Description

Technical Field

[0001] This application relates to the field of computer input device technology, and in particular to a keyboard support structure. Background Technology

[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] As keyboards have evolved, they have evolved to meet different usage needs in various scenarios. For example, in scenarios where only numbers need to be input, keyboards are simplified to an 18-key layout; while in scenarios with lower number input requirements, the number pad on the right side of a standard keyboard is simplified and removed, resulting in an 87-key layout. To accommodate the user's input posture, conventional keyboards are equipped with a support structure, namely foldable or unfoldable legs on the back cover. By extending or folding the legs from the back cover, the keyboard can be positioned at different angles relative to the desktop, allowing it to be raised or placed horizontally. However, this support structure only offers two modes—folding or unfolding—making it difficult to meet higher adjustment needs and limiting its adaptability. Utility Model Content

[0004] The purpose of this application is to provide a keyboard support structure that aims to improve the limited keyboard support modes in related technologies, increase keyboard comfort, and enhance the user experience.

[0005] This application provides a keyboard support structure, including a lower support assembly, a telescopic assembly disposed on the lower support assembly, and an upper support assembly disposed on the telescopic assembly; the telescopic assembly includes a support base disposed on the lower support assembly, a guide slide seat disposed on the support base, and a push rod slidably connected to the guide slide seat; the support base has a lower hinge block, which is hinged to the lower support assembly; the guide slide seat 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 upper support assembly.

[0006] Furthermore, the guide slide is provided with a locking block for cooperating with the push rod. The locking block is detachably connected to the side of the guide slide near the upper support assembly, and the guide hole is located in the locking block.

[0007] Furthermore, the guide slide has several limiting grooves on the side near the upper support assembly, and the locking block 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.

[0008] Furthermore, the telescopic assembly also includes a telescopic drive member for driving the push rod, the telescopic drive member being disposed on the support base and facing the push rod, and the end of the push rod away from the upper support assembly being connected to the telescopic drive member.

[0009] Furthermore, the lower support assembly includes a lower support cover, and the side of the lower support cover is provided with a lower adapter groove for adapting and installing the telescopic assembly, and one end of the telescopic assembly is fitted into the lower adapter groove.

[0010] Furthermore, a hinge assembly is provided at the connection between the lower support cover and the upper support assembly, and the lower support cover is rotatably connected to the upper support assembly through the hinge assembly; the hinge assembly includes a hinge pivot, a first connecting hinge and a second connecting hinge rotatably connected to the hinge pivot, the first connecting hinge is disposed on the lower support cover, and the second connecting hinge is disposed on the upper support assembly.

[0011] Furthermore, the lower adapter groove is divided into a lower mounting groove and a lower main body cavity. The support seat is fitted into the lower main body cavity, and the lower hinge block is fitted into and rotatably connected to the lower mounting groove.

[0012] Furthermore, a clearance groove is provided at one end of the support base near the lower mounting groove.

[0013] Furthermore, the upper support assembly includes an upper support cover, which has an upper adapter groove for fitting and installing the telescopic assembly, and the other end of the telescopic assembly is fitted into the upper adapter groove.

[0014] The beneficial effects of this application are:

[0015] 1. A keyboard support structure according to this application comprises a lower support component, a telescopic component, and an upper support component. The lower support component is placed on the desktop for support, and the upper support component supports the keyboard keys. The telescopic component utilizes a support base, a guide slide, and a push rod. By simply driving the push rod to slide within the guide hole of the guide slide, the upper support component can be driven to swing, thereby causing the keyboard keys to swing. Since the sliding of the push rod has several adjustable strokes, the upper support component can achieve a large range of swing, thus realizing multi-angle adjustment. Compared with the two support modes of keyboards in related technologies, the keyboard support structure can achieve a wider range of angle adjustment, effectively increasing the keyboard adjustment range and improving the comfort of the operator.

[0016] 2. A keyboard support structure of this application installs a telescopic component by opening corresponding lower and upper adapter slots on the lower and upper support covers, so that the telescopic component is fitted into the support component in a fitting manner. On the one hand, this can prevent the telescopic component from protruding from the keyboard and occupying additional space outside the keyboard. On the other hand, it can protect the telescopic component and prevent it from failing due to external collisions, thereby increasing the stability and service life of the keyboard support structure.

[0017] 3. A keyboard support structure of this application, by setting a locking block with a guide hole on the guide slide, and the locking block being detachably connected to the guide slide, can conveniently disassemble the locking block to repair and maintain the push rod, and can conveniently replace the locking block with a different hole diameter to adapt to push rods of different diameters, so as to meet the pushing force requirements of keyboards of different weights and sizes, making the keyboard support structure compact and easy to manufacture.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] 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.

[0029] 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.

[0030] Reference Figure 1 as well as Figure 2 This application provides a keyboard support structure, including a lower support component 1, a telescopic component 2 disposed on the lower support component 1, and an upper support component 3 disposed on the telescopic component 2. The lower support component 1 is used to place on a desktop for support, the upper support component 3 supports the keyboard keys, and the telescopic component 2 is used to extend and retract to adjust the angle between the lower support component 1 and the upper support component 3.

[0031] Specifically, in this embodiment, for ease of description, the side of the keyboard used for support on the desktop is designated as the bottom, the side facing the keyboard keys 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. The lower support assembly 1 includes a lower support cover 11, which is located below one side of the upper support assembly 3. In order to install the telescopic assembly 2, the side of the lower support cover 11 has a lower adapter groove 111 for fitting and installing the telescopic assembly 2. One end of the telescopic assembly 2 in the length direction is fitted into the lower adapter groove 111.

[0032] Reference Figure 2 as well as Figure 3 There are two telescopic components 2, which are respectively disposed on both sides of the lower support cover 11. Taking a single telescopic component 2 as an example, the telescopic component 2 includes a support seat 21 disposed on the lower support component 1, a guide slide seat 22 disposed on the support seat 21, and a push rod 23 slidably connected to the guide slide seat 22. The support seat 21 is used to provide support for the guide slide seat 22 and the push rod 23. The support seat 21 is cylindrical and has a cavity inside to accommodate the installation of the guide slide seat 22 and the push rod 23. The end of the support seat 21 near the lower support cover 11 has a lower hinge block 211, which is hinged to the lower support cover 11 of the lower support component 1.

[0033] In this embodiment, to prevent the telescopic component 2 from protruding and occupying space outside the keyboard, the lower adapter slot 111 is divided into a lower mounting slot 1111 and a lower main body cavity 1112. The support base 21 is fitted into the lower main body cavity 1112, and the lower hinge block 211 is fitted into and rotatably connected to the lower mounting slot 1111. This arrangement allows the telescopic component 2 to be fitted into the lower support cover 11. On the one hand, it can prevent the telescopic component 2 from protruding from the lower support cover 11 and occupying additional space outside the keyboard. On the other hand, it can protect the telescopic component 2 and prevent it from failing due to external collisions, thereby increasing the stability and service life of the keyboard support structure. Meanwhile, considering the swinging requirements of the telescopic component 2, a clearance groove 212 is provided at one end of the support base 21 near the lower mounting groove 1111. The clearance groove 212 extends along the length of the support base 21 and faces the edge and inner wall of the lower support cover 11. With this arrangement, the clearance groove 212 can provide more swinging space when the telescopic component 2 swings or is installed, making the structure of the telescopic component 2 compact and easy to assemble. It is understood that the size and specific position of the clearance groove 212 can be adjusted according to actual needs.

[0034] The guide slide 22 is installed on one end of the support base 21 near the upper support cover 31. Specifically, the guide slide 22 can be installed on the support base 21 via a threaded connection. The guide slide 22 has a guide hole 221 for engaging the push rod 23, the shape of which is adapted to the shape of the push rod 23. The push rod 23 includes a rod body 231 slidably connected to the guide hole 221, abutting against the guide hole 221. The rod body 231 has an upper hinge block 232, which is hinged to the upper support assembly 3. Since different keyboards have different weights and sizes, the size and shape of the push rod 23 will also vary. To better accommodate different push rods 23, the guide slide 22 is provided with a locking block 222 for engaging the push rod 23. The locking block 222 is detachably connected to the side of the guide slide 22 near the upper support assembly 3, and the guide hole 221 is located in the locking block 222. In this embodiment, the guide slide 22 has several limiting grooves on the side near the upper support assembly 3. These limiting grooves are evenly arranged along the edge of the guide slide 22. The locking block 222 has corresponding protrusions 2221. The limiting grooves and protrusions 2221 are the same in number and correspond one-to-one. The protrusions 2221 are fitted into the limiting grooves. With this arrangement, when the diameter or shape of the push rod 23 changes, only the guide slide 22 with the corresponding guide hole 221 needs to be replaced for quick adaptation, without the need to redesign and manufacture the entire telescopic assembly 2. In addition, the telescopic assembly 2 also includes a telescopic drive member 24 for driving the push rod 23. The telescopic drive member 24 is disposed on the support 21 and faces the push rod 23. The end of the push rod 23 away from the upper support assembly 3 is connected to the telescopic drive member 24. In this embodiment, the telescopic drive member 24 is an electric cylinder. The telescopic drive member 24 is installed and fixed in the cavity of the support 21, and the piston end of the telescopic drive member 24 is connected to the push rod 23.

[0035] Reference Figure 4 as well as Figure 5To facilitate connection and rotation, a hinge assembly 4 is provided at the connection between the lower support cover 11 and the upper support assembly 3. The lower support cover 11 is rotatably connected to the upper support assembly 3 via the hinge assembly 4. In this embodiment, the hinge assembly 4 includes a hinge pivot 41, a first connecting hinge 42 rotatably connected to the hinge pivot 41, and a second connecting hinge 43. The first connecting hinge 42 is located on the lower support cover 11, and the second connecting hinge 43 is located on the upper support assembly 3. Specifically, the hinge assembly 4 is located at one end of the lower support cover 11 near the upper support assembly 3. There are two hinge assemblies 4, located at opposite ends of the length direction at the connection between the lower support assembly 11 and the upper support assembly 3. Taking a single hinge assembly 4 as an example, the hinge pivot 41 is rotatably connected between the lower support cover 11 and the upper support assembly 3. The first connecting hinge 42 is threadedly connected to the lower support cover 11, and the second connecting hinge 43 is threadedly connected to the upper support assembly 3. With this configuration, the hinge component 4 can connect the lower support component 1 and the upper support component 3 to ensure the connection strength; when the lower support component 1 and the upper support component 3 are unfolded, the hinge component 4 acts as a limit, and the lower support component 1 and the upper support component 3 can move along a predetermined path to unfold.

[0036] Reference Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The upper support assembly 3 includes an upper support cover 31. Similarly, the upper support cover 31 has an upper adapter groove 311 for fitting and installing the telescopic assembly 2. The other end of the telescopic assembly 2 is fitted into the upper adapter groove 311. The upper adapter groove 311 is divided into an upper mounting groove and an upper main body cavity. The upper hinge block 232 is fitted and hinged in the upper mounting groove. The support seat 21 and the guide slide seat 22 are fitted into the upper main body cavity to achieve a fitted installation.

[0037] To facilitate the installation of the hinge assembly 4, the upper support cover 31 has an adapter groove whose shape matches the shape of the hinge assembly 4, and the hinge assembly 4 is fitted into the adapter groove. More specifically, the adapter groove is divided into a pivot groove and a hinge groove. The hinge pivot 41 is fitted into the pivot groove, which is a through groove with clearances on both sides to facilitate the installation and engagement of the hinge pivot 41. The second connecting hinge 43 is connected to the upper support cover 31 by a threaded connection. When the lower support assembly 1 and the upper support assembly 3 are unfolded, the first connecting hinge 42 flips on the lower support cover 11 around the hinge pivot 41, and the second connecting hinge 43 flips on the upper support cover 31 around the hinge pivot 41, thereby ensuring angle adjustment between the two.

[0038] In addition, the upper support cover 31 also has an upper flange 312 that cooperates with the lower support cover 11. The lower support cover 11 has a lower cavity that cooperates with the upper flange 312. The upper flange 312 is fitted into or disengaged from the lower cavity. That is, the upper support cover 31 cooperates with the lower support cover 11 by fitting the upper flange 312, so that the upper support cover 31 and the lower support cover 11 are tightly fitted, which facilitates positioning, installation and opening and closing. The hinge assembly 4 is also located in the lower cavity.

[0039] Reference Figure 6 as well as Figure 7 When adjustment is needed, the telescopic drive component 24 is activated, and the piston-end drive push rod 23 extends from the guide slide seat 22. The extended push rod 23 lifts the upper support assembly 3, causing the upper support assembly 3 to form an angle with the lower support assembly 1. 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 24 can also be a cylinder. It is understood that the telescopic assembly 2 does not depend on the telescopic drive component 24 for operation. In some embodiments, the guide slide hole 221 can be fitted with the rod body 231 by interference fit or damping connection. Even without the telescopic drive component 24, the rod body 231 can still be fixed by extending to different lengths and abutting against the guide slide hole 221, thereby enabling a wide range of angle adjustments.

[0040] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
