Technical Field

[0001] This utility model relates to the field of keyboard tray mechanism technology, specifically to a storage rack and device. Background Technology

[0002] In a competitive market, devices are becoming increasingly functional, with some requiring multiple LCD displays for viewing various data and images. These displays need keyboards for inputting information and commands. If each display had its own keyboard, it would not only increase manufacturing and maintenance costs but also make the device bulky and require more floor space. Sharing a single keyboard across multiple displays solves these problems.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a rack and device to solve the technical problem that multiple monitors cannot share a single keyboard in related technologies.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: a shelf is provided, comprising: a mounting column, on which at least two first products are mounted, the at least two first products being spaced apart around the axis of the mounting column; a rotating frame, on which a second product is mounted, the rotating frame being rotatably connected to the mounting column so that the second product and any one of the first products are located on the same side of the mounting column.

[0006] Furthermore, the rotating frame has mounting holes, the axis of which coincides with the axis of the mounting hole, a mounting post passes through the mounting hole, and a bearing is installed between the mounting hole and the mounting post.

[0007] Furthermore, the rack includes a rotation damper, which is mounted on a mounting column and connected to the rotating frame. The rotation axis of the rotation damper coincides with the rotation axis of the rotating frame, and the rotation damper is used to adjust the rotation speed of the rotating frame.

[0008] Furthermore, the shelf includes a limiting sleeve that extends along the axis of the mounting column and is fitted onto the mounting column. A rotational damper is mounted on the outer circumferential surface of the limiting sleeve, and damper limiting portions are respectively provided at both ends of the rotational damper on the limiting sleeve.

[0009] Furthermore, the rotary damper includes: a damping copper sleeve, which is fitted onto the limiting sleeve; and an expansion sleeve, which is fitted onto the damping copper sleeve. The radial expansion degree between the expansion sleeve and the limiting sleeve is adjustable, and the expansion sleeve is connected to the rotating frame.

[0010] Furthermore, the limiting sleeve is provided with limiting grooves distributed circumferentially around the axis of the limiting sleeve, and limiting sidewalls are formed at both ends of the limiting grooves. The tightening sleeve is provided with limiting protrusions corresponding to the limiting sidewalls, and the limiting protrusions can abut against the limiting sidewalls.

[0011] Furthermore, a tray is installed on the rotating frame, on which a second product is loaded. The end of the tray near the rotating frame is connected to the rotating frame. The tray is rotatably arranged around its extension direction so that the tray can switch between a working state and a storage state. When the tray is in the working state, the tray is unfolded, and when the tray is in the storage state, the tray is folded.

[0012] Furthermore, the shelf includes: a flip block, which is connected to one end of the tray near the rotating frame; and a damping hinge shaft, one end of which is connected to the rotating frame and the other end of which is connected to the flip block; wherein, there are two flip blocks and two damping hinge shafts, and the two flip blocks are located on both sides of the rotating frame.

[0014] An apparatus comprising the aforementioned rack. Beneficial effects: 1. The rotating frame is rotatably connected to the mounting column, allowing the second product to rotate to a designated position on the mounting column. This ensures the second product is on the same side of the mounting column as the designated first product. For example, when the first product is a display screen and the second product is a mouse or keyboard, rotating the frame at a certain angle allows switching between different display screens. This ensures the mouse or keyboard is on the same side of the mounting column as the designated display screen, facilitating the use of the same mouse or keyboard to view different monitors and input information and commands.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] According to an embodiment of this utility model, a storage rack is provided; please refer to [link / reference]. Figures 1 to 12 It includes: a mounting column 1, on which at least two first products 10 are mounted, and the at least two first products 10 are spaced apart around the axis of the mounting column 1; a rotating frame 2, on which a second product 20 is mounted, and the rotating frame 2 is rotatably connected to the mounting column 1 so that the second product 20 and any one of the first products 10 are located on the same side of the mounting column 1.

[0020] It should be noted that the quantity of the first product 10 is at least two, and can be set to two, three, four, etc., depending on actual usage requirements. The installation method of the first product 10 can also be selected as needed. For example, if the quantity of the first product 10 is small and the installation space around the mounting column 1 is large enough, the first product 10 can be directly installed on the mounting column 1. When the space around the mounting column 1 is insufficient to install the first product 10, other structures can be used to support the first product 10.

[0021] Specifically, the rotating frame 2 is rotatably connected to the mounting column 1, and the second product 20 can be rotated to a designated position on the mounting column 1 so that the second product can be located on the same side of the mounting column 1 as the designated first product 10. For example, when the first product 10 is a display screen and the second product 20 is a mouse or keyboard, by rotating the rotating frame 2 at a certain angle, it is possible to switch between different display screens, so that the mouse or keyboard is located on the same side of the mounting column 1 as the designated display screen, making it convenient for users to use the same set of mouse or keyboard to view different monitors and input information and commands.

[0022] Preferably, for example, when the first product 10 is a display screen, and there are two first products 10, the two display screens can be directly mounted on the mounting post 1, with the two display screens facing away from each other. In this case, the rotation angle of the rotating frame 2 is 180°. See [link / reference] Figure 1 When using monitor 101, keyboard 201 and mouse 202 are located on the same side as monitor 101, facilitating input control of monitor 101 via keyboard 201 and mouse 202; see also Figure 3 When using monitor 2 102, simply rotate the rotating bracket 2 horizontally by 180° with the mounting column 1 as the axis. By rotating the rotating bracket 2 by 180°, the keyboard 201 and mouse 202 are located on the same side as monitor 2 102, which facilitates input control of monitor 2 102 through the keyboard 201 and mouse 202.

[0023] The rack in this embodiment enables multiple monitors to share a single keyboard or mouse, reducing equipment manufacturing and maintenance costs, simplifying the overall structure of the equipment, and reducing the equipment's footprint. It also solves the technical problem in related technologies where multiple monitors cannot share a single keyboard.

[0024] In the shelf of this embodiment, see Figure 5 or Figure 10 The rotating frame 2 has a mounting hole 21, the axis of which coincides with the axis of the mounting hole 21. A mounting post 1 passes through the mounting hole 21, and a bearing 22 is installed between the mounting hole 21 and the mounting post 1. Specifically, by setting the bearing 22, the rotating frame 2 can effectively reduce frictional resistance during rotation. The mounting hole 21 and the mounting post 1 are rotatably connected by the bearing 22, ensuring that the rotating frame 2 can rotate smoothly around the mounting post 1.

[0025] Preferably, the bearing 22 is an angular contact ball bearing, which enables it to withstand not only radial loads but also axial loads, so that the rotating frame 2 does not move or shift axially.

[0026] In the shelf of this embodiment, see Figure 5 or Figure 10The rack includes a rotation damper 3, which is mounted on the mounting column 1 and connected to the rotating frame 2. The rotation axis of the rotation damper 3 coincides with the rotation axis of the rotating frame 2. The rotation damper 3 is used to adjust the rotation speed of the rotating frame 2. By setting the rotation damper 3, the rotation damper 3 can add a damping effect during the rotation of the rotating frame 2 when it is manually rotated, making the feel more comfortable and ensuring that the rotating frame 2 will not move too fast or too violently due to inertia during the rotation.

[0027] In the shelf of this embodiment, see Figure 5 or Figure 10 The shelf includes a limiting sleeve 4, which extends along the axis of the mounting column 1 and is fitted onto the mounting column 1. A rotational damper 3 is mounted on the outer circumferential surface of the limiting sleeve 4, and damper limiting portions 41 are respectively provided at both ends of the rotational damper 3 on the limiting sleeve 4. Specifically, the position of the rotational damper 3 is limited by the damper limiting portions 41 to prevent unnecessary axial displacement or loosening of the rotational damper 3 during rotation.

[0028] It should be noted that the mounting post 1 is a fixing component, and the limiting sleeve 4 is radially limited to the mounting post 1 through a flat key or keyway structure. The mounting hole 21 is a multi-segment stepped hole, and the limiting sleeve 4 is also located inside the mounting hole 21.

[0029] In some embodiments, a damper mounting groove 43 is recessed on the outer peripheral surface of the limiting sleeve 4, the axis of the damper mounting groove 43 coincides with the axis of the limiting sleeve 4, and a damper limiting portion 41 is formed on the bottom end face of the damper mounting groove 43. A shaft elastic retaining ring 72 is installed on the top of the damper mounting groove 43 as a damper limiting portion at the top of the rotary damper 3, and the shaft elastic retaining ring 72 is groundably disposed with respect to the top of the rotary damper 3.

[0030] In some embodiments, a retaining ring 71 for a bore is installed at the bottom of the bearing 22, and the retaining ring 71 abuts against the bottom of the bearing 22 to limit the bearing 22.

[0031] In some embodiments, the end of the limiting sleeve 4 near the bearing 22 abuts against the bearing 22 to axially limit the bearing 22.

[0032] In the shelf of this embodiment, see Figure 5 or Figure 10The rotary damper 3 includes: a damping copper sleeve 31, which is fitted onto the limiting sleeve 4; and an expansion sleeve 32, which is fitted onto the damping copper sleeve 31. The radial tension between the expansion sleeve 32 and the limiting sleeve 4 is adjustable, and the expansion sleeve 32 is connected to the rotating frame 2. Thus, the radial tension between the expansion sleeve 32 and the limiting sleeve 4 is adjustable, and by adjusting the damping torque of the rotary damper 3, optimal rotational resistance and comfort can be achieved.

[0033] In some embodiments, one end of the expansion sleeve 32 is fixed to the rotating frame 2 by a screw, and the part that fits onto the mounting post 1 is an open design. At the same time, a damping copper sleeve 31 is installed inside the expansion sleeve 32 ring. The damping copper sleeve 31 contacts the limiting sleeve 4. The damping copper sleeve 31 is also an open design. In this way, by simply tightening the screw at the opening of the expansion sleeve 32, the radial tightness between the expansion sleeve 32 and the limiting sleeve 4 can be adjusted by tightening the damping copper sleeve 31, thereby adjusting the damping torque of the rotary damper 3.

[0034] In some embodiments, the damping copper sleeve 31 is made of oil-immersed copper, which has wear resistance and self-lubricating properties.

[0035] In some embodiments, the outer side of the rotating bracket 2 has a hole for inserting an Allen wrench to adjust the screw at the opening of the tightening sleeve 32 at any time.

[0036] In the shelf of this embodiment, see Figure 1 and Figures 11-12 The limiting sleeve 4 is provided with limiting grooves 42 distributed circumferentially around the axis of the limiting sleeve 4. The two ends of the limiting grooves 42 respectively form limiting sidewalls 421. The tightening sleeve 32 is provided with limiting protrusions 321 corresponding to the limiting sidewalls 421. The limiting protrusions 321 can abut against the limiting sidewalls 421. In this way, the stroke of the rotating frame 2 can be limited. The two ends of the limiting grooves 42 respectively form the starting point and the ending point of the stroke, so that the rotating frame 2 can only complete a certain angle of rotation on the mounting column 1.

[0037] Preferably, when there are two first products 10, the rotation angle of the rotating frame 2 is 180°, and the central angle of the limiting groove 42 is 180°, ensuring that the rotating frame 2 can only rotate 180° on the mounting column 1. By setting the limiting groove 42 and the limiting protrusion 321, the positions of the two first products 10 can be positioned respectively, so that the rotating frame 2 can be accurately aligned with the required first product 10, improving the comfort of use.

[0038] In the shelf of this embodiment, see Figure 2 or Figure 4A tray 5 is installed on the rotating frame 2, and a second product 20 is loaded on the tray 5. The end of the tray 5 near the rotating frame 2 is connected to the rotating frame 2. The tray 5 is rotatably arranged around the extension direction of the tray 5 so that the tray 5 can switch between working state and storage state. When the tray 5 is in working state, the tray 5 is unfolded. When the tray 5 is in storage state, the tray 5 is folded.

[0039] It should be noted that when the second product 20 is a keyboard, the tray 5 is used as a keyboard tray. The wider the keyboard tray, the more area the operator can place their arm when using the keyboard, and the more comfortable the operator is to use it. However, the problem with a wider keyboard tray is that it increases the footprint of the keyboard tray.

[0040] In summary, in order to solve the above problems and further reduce the footprint of the keyboard tray and the usable area of ​​the device, the tray 5 in this application has a flipping function, which allows the second product to be folded in the non-working state for easy storage and to reduce the footprint of the tray 5. When the second product 20 is a keyboard, it can save the footprint of the device while ensuring the comfort of operating the keyboard, especially during the process of device shutdown or transportation, to avoid bumping the keyboard tray.

[0041] It should be noted that, see Figure 2 or Figure 4 When the first product 10 is a display screen, when the tray 5 is in the storage state, the tray 5 is folded and the tray 5 is in a nearly parallel position with the display screen, so that the keyboard 201 is directly in front of the display screen. During the equipment is not in use or during transportation, it protects the screen of the fragile LCD monitor from being bumped or broken.

[0042] In some embodiments, when the second product 20 is a keyboard, the keyboard is fixed to the tray 5 by screws or a pressure plate.

[0043] In the shelf of this embodiment, see Figure 6The tray includes: a flip block 6, which is connected to the end of the tray 5 near the rotating frame 2; and a damping hinge shaft 61, one end of which is connected to the rotating frame 2, and the other end of which is connected to the flip block 6. There are two flip blocks 6 and two damping hinge shafts 61, located on opposite sides of the rotating frame 2. By setting the flip blocks 6, one end of the damping hinge shaft 61 is hydraulically pressed into the rotating frame 2, and the other end is hydraulically pressed into the two flip blocks 6. The two flip blocks 6 are then fixed to the tray 5 with screws, ultimately achieving the flipping action and giving the tray 5 a flipping function. The damping hinge shaft 61 provides resistance relief during the unfolding or folding of the tray 5, ensuring that the keyboard tray can stop at any position within its travel range. This prevents the tray 5 from not naturally rebounding after being folded, requiring a certain amount of force to move. In this case, the tray 5 can protect the monitor screen and save space.

[0044] In some embodiments, the damping hinge shaft 61 employs a prior art damping hinge shaft, and the damping directions provided by the two components are symmetrical. Through force analysis, the torque required for the two embedded damping hinges is calculated. For example, the final effect is that the required operating force is maintained at approximately 40N whether the keyboard tray 5 is flipped up or down, while ensuring that the keyboard tray will not flip freely when it is flipped up to 90°, and will only flip down when a 40N force is applied by a person.

[0045] In some embodiments, see Figure 7 When the pallet 5 is in the working state, the pallet 5 unfolds. A first flip-limiting protrusion 56 is provided on the pallet 5. The first flip-limiting protrusion 56 is an elongated protrusion structure arranged along the rotation axis of the pallet 5. It abuts against the lower end face of the rotating frame 2 along the first flip-limiting protrusion 56, thereby limiting the stroke of the rotating frame 2; see also Figure 8 When the tray 5 is in the retracted state, it is folded. A second flip-limiting protrusion 57 is provided on the tray 5. The second flip-limiting protrusion 57 is an elongated protrusion structure arranged along the rotation axis of the tray 5. The second flip-limiting protrusion 57 abuts against the upper end face of the rotating frame 2, thereby limiting the stroke of the rotating frame 2. At this time, the flip range of the rotating frame 2 is 0° to 90°. When the tray 5 is in the working state, the flip angle of the rotating frame 2 is 0°. When the tray 5 is in the retracted state, the flip angle of the rotating frame 2 is 90°. The second product 20 and the first product 10 are approximately parallel or parallel to each other.

[0046] In the shelf of this embodiment, see Figure 9The rotating frame 2 is provided with a first wiring groove 23, which is connected to the first wiring inlet 231 and the first wiring outlet 232 respectively; the tray 5 is provided with a second wiring inlet 51 and a second wiring groove 52 connected to the second wiring inlet 51, the second wiring inlet 51 is connected to the first wiring outlet 232, and the second wiring groove 52 is used to provide wiring for the second product 20.

[0047] Specifically, the rotating frame 2 is provided with a first cable routing groove 23, which extends along the structural direction of the rotating frame 2. One end of the first cable routing groove 23 is connected to a first cable inlet 231 provided on the rotating frame 2, and the other end is connected to a first cable outlet 232, used to guide and accommodate the cable connecting the second product 20. The cable passes through the first cable outlet 232 and the second cable inlet 51 and enters the second cable routing groove 52. For example, when the first product 10 is a display screen and the second product 20 is a mouse or keyboard, the display screen and the keyboard or mouse are connected by cables through the above cable routing groove.

[0048] In the shelf of this embodiment, see Figure 9 The rotating frame 2 has a clearance groove 24 at one end near the tray 5, and a first cable outlet 232 is provided in the clearance groove 24; the tray 5 has a protrusion 53 at one end near the rotating frame 2 corresponding to the clearance groove 24, the protrusion 53 is embedded in the clearance groove 24, the protrusion 53 has a second cable inlet 51 and a cable channel 54 connected to the second cable inlet 51, and the cable channel 54 is collinear with the rotation axis of the tray 5.

[0049] In this embodiment, the rotating rack 2 has a clearance groove 24 at one end near the tray 5. This clearance groove 24 is used to accommodate the protrusion 53 and has a first cable routing outlet 232 inside. Correspondingly, the tray 5 has a protrusion 53 at the position corresponding to the clearance groove 24 at one end near the rotating rack 2. The protrusion 53 can be stably embedded in the clearance groove 24 when the tray 5 is in the working position or the storage position. The protrusion 53 has a second cable routing inlet 51 and a cable routing channel 54 communicating with it. When the protrusion 53 is embedded in the clearance groove 24, the second cable routing inlet 51 and the first cable routing outlet 232 are spatially connected, and the cable routing channel 54 leads to the second cable routing groove 52.

[0050] Specifically, the central axis of the cable routing channel 54 is collinear with the rotation axis of the tray 5 as it rotates, preventing the cable at the rotation center of the tray 5 from being squeezed or bent during the rotation process and preventing the cable from being damaged. At the same time, by constraining the cable routing path on the rotation axis, the space of the cable is limited, preventing it from being exposed or tangled during the movement. In addition, the overall neatness and reliability of the wiring are improved, and the aesthetics of the equipment are enhanced.

[0051] In some embodiments, a winding post is provided inside the protrusion 53 for organizing and splitting the cable. For example, when the second product includes a keyboard 201 and a mouse 202, the cable entering the second cable entry 51 can be split into two strands and connected to the keyboard 201 and the mouse 202 respectively.

[0052] In some embodiments, the back of the rotating frame 2 is provided with a rotating frame cover plate 25, and the back of the tray 5 is provided with a tray cover plate 55. The back of the rotating frame 2 and the tray 5 are machined with grooves, and the keyboard and mouse cables can be routed in the grooves, and then covered by the rotating frame cover plate 25 and the tray cover plate 55.

[0053] It should be noted that when flipping the tray 5, you can choose to remove the mouse 202 from the tray 5, or you can add a special fixing device to fix the mouse 202 to prevent the mouse 202 from falling.

[0054] In some embodiments, when the first product 10 is a display screen and the second product 20 is a mouse or keyboard, when operating with display one 101, the tray 5 is initially positioned opposite to display one 101. When switching to display two, simply drag the tray 5 manually around the mounting post 1 as the axis and rotate it horizontally 180° to reach display two 102. During the entire rotation of the rotating frame 2, the rotation damper 3, through the cooperation of the expansion sleeve 32 and the damping copper sleeve 31, ensures that the rotation of the rotating frame 2 is smooth. The limiting groove and the limiting protrusion of the limiting sleeve 4 interact to achieve the stroke positioning of the rotating frame 2.

[0055] When tray 5 needs to be switched from the retracted state to the working state, the operator manually applies force to make tray 5 rotate around the embedded damping hinge axis until tray 5 is unfolded, at which point tray 5 is perpendicular to the display screen. After the keyboard is finished using, when tray 5 needs to be switched from the working state to the retracted state, the operator manually applies force again to make tray 5 rotate back to the upper 90° position around the embedded damping hinge axis. The keyboard and mouse are then flipped upwards, no longer occupying equipment space, while providing effective screen protection for monitor 1.

[0056] In the device of this embodiment, the device includes the aforementioned shelf.

[0057] This application provides a device that integrates the aforementioned rack design. By combining the rack with the main body of the device, it enables the keyboard or mouse to be flexibly switched between different displays when the device carries multiple displays. For example, the rotating frame 2 in the device can support the keyboard and rotate smoothly around the axis of the mounting column 1, ensuring that the user can easily and quickly position the keyboard to the position corresponding to the desired display. This allows multiple displays to share a single keyboard or mouse, reducing manufacturing and maintenance costs, simplifying the overall structure of the device, and reducing its footprint.

[0058] Meanwhile, the flip function of the second product 20 allows the second product to be folded when it is not in operation, which significantly reduces the overall footprint of the device and effectively protects the first product 10 from external impact damage, thus improving the safety of the display screen.
