Description

Technical Field

[0001] This invention belongs to the technical field of instruments or dashboards for special vehicles, including display consoles, and particularly relates to a keyboard bracket, a display console, and an operating method. Background Technology

[0002] A display console is a human-machine interface device with functions such as operation, control, and display. Certain special vehicles (such as military command vehicles, electronic warfare vehicles, communication command vehicles, and telemetry and control vehicles) are equipped with multi-functional display consoles or similar instruments / dashboards. These consoles are typically accompanied by a specific keyboard. Due to changes in the operating environment and operators, it is often necessary to adjust the keyboard to different angles and positions for optimal usability. However, existing display consoles and similar instruments / dashboards generally use a fixed keyboard design, which is insufficient to meet the specific keyboard angle requirements of users. Summary of the Invention

[0003] The purpose of this invention is to provide a keyboard stand, a display console, and an operating method to solve the problem that the existing display consoles generally use fixed keyboards, especially the fixed keyboard design for special vehicles, which cannot adapt to angle adjustments under various needs.

[0004] In a first aspect, the present invention provides a keyboard stand for a display console. The keyboard stand includes a base, an operating area on the top of the base, a plurality of operating keys on the operating area, and a plurality of adjustment components on the bottom of the base for supporting the base. The adjustment components include a gear, a first rack, a second rack, and a support shaft. A first end of the support shaft is rotatably connected to a predetermined position on the base, and a second end of the support shaft is rotatably connected to the gear. The gear meshes with the first rack and the second rack. The gear is capable of moving along the first rack and the second rack, and when the gear moves, it can drive the first end to rise or fall.

[0005] This application provides an adjustment component at the bottom of the base to support it. This component includes mutually transmitting gears, a first rack, a second rack, and a support shaft. When the angle or position of the keyboard bracket needs adjustment, one of the first and second racks drives the gear to roll along their respective extension directions. Simultaneously, the rolling gear causes the support shaft to oscillate, thus changing the angle of the base and achieving the desired adjustment of the keyboard bracket. Having multiple adjustment components at the bottom of the base allows for greater flexibility in angle and position adjustments, better meeting various angle adjustment needs, especially for special vehicles operating in different environments (particularly mountainous terrain).

[0006] In addition, by making the adjustment component include a gear, a first rack and a second rack, the locking function of the base can be well realized when the gear and the first rack and the second rack are relatively stationary under the meshing of the gear, the first rack and the second rack. This makes the keyboard bracket more stable after the angle and position are adjusted, and can better meet the keyboard operation needs of special vehicles in complex working environments.

[0007] In one embodiment, both the first rack and the second rack extend in a horizontal direction. The first rack is fixed to the side wall of the display console, and the second rack is movable in a horizontal direction. The adjustment component is configured such that when the second rack moves in a horizontal direction, the gear drives the second end of the support shaft to move in a horizontal direction, and the first end of the support shaft swings around the second end of the support shaft.

[0008] In one embodiment, the base is generally square in shape, the keyboard bracket includes four adjustment components, the base includes a first side and a second side opposite to the first side; two adjustment components are provided below the first side and below the second side, the second racks included in the two adjustment components below the first side are collinearly arranged, the second racks included in the two adjustment components below the second side are collinearly arranged, and the two second racks below the first side and the two second racks below the second side are arranged parallel to each other.

[0009] In one embodiment, a groove extending along the movement direction of the second rack is provided on the outer wall of the operating area, and a protrusion is provided on the second rack. The protrusion extends out from the inner side of the groove and can slide along the groove.

[0010] In one embodiment, a plurality of receiving slots and a cleaning component corresponding to each of the plurality of receiving slots are provided between adjacent plurality of operation keys.

[0011] In one embodiment, the receiving groove includes a first inclined surface and a second inclined surface. When the keyboard bracket is in a horizontal state, the receiving groove is vertically recessed downward along the upper surface of the keyboard bracket, so that the entire receiving groove is located below the vertical direction of the operation keys, thereby allowing dust or debris to fall naturally into the bottom of the groove under the action of gravity.

[0012] In one embodiment, the cleaning assembly includes a suction tube with a suction port movable along the bottom of the receiving groove.

[0013] In one embodiment, the receiving groove is provided with a storage strip, which is laid at the bottom of the receiving groove along the extending direction of the receiving groove; the suction port of the suction tube is provided with an openable baffle, and the storage strip is provided with a slot. When the baffle is in the open state, the baffle extends beyond the edge of the storage strip, and at least a portion of the baffle is engaged in the slot, so that the suction port can drive the storage strip to move via the baffle.

[0014] Secondly, the present invention also provides a display console, the display console including a keyboard bracket as described in any of the foregoing embodiments, the display console having a keyboard placement area, and the keyboard bracket being disposed in the keyboard placement area.

[0015] Thirdly, the present invention also provides a method for operating a keyboard stand, for operating a keyboard stand as described in any of the foregoing embodiments, including adjusting at least one adjustment component so that the predetermined position of the keyboard stand reaches a predetermined height, thereby changing the overall posture of the keyboard stand.

[0016] Fourthly, the present invention also provides another method for operating a keyboard stand, comprising the following steps:

[0017] Step S1: Adjust multiple adjustment components to allow dust and debris near the operation keys to fall into the storage strip in the receiving slot;

[0018] Step S2: Control the suction tube to move along the bottom of the receiving tank to suck away the dust and debris at the bottom of the receiving tank;

[0019] Step S3: Pull the storage belt to move it along the receiving groove, and the storage belt will carry the dust and debris attached to its surface away from the receiving groove area.

[0020] Compared with the prior art, the keyboard stand and operating method of the present invention can achieve at least one of the following beneficial effects:

[0021] This invention provides a keyboard stand, a display console, and an operating method. The keyboard stand includes a base, with several operation keys on the top and several adjustment components on the bottom. By adjusting the components, the base can be raised or lowered to a predetermined position, thereby changing the overall position and posture of the keyboard. This solves the problem that the fixed keyboard design in the prior art cannot adapt to angle adjustments under various needs. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0036] It should also be noted that the directional terms such as left, right, up, down, and front / back in this embodiment are only relative concepts or references to the normal use of the product, and should not be considered restrictive. In this embodiment, the positive direction of the Z-axis refers to up, the negative direction of the Z-axis refers to down, the positive direction of the Y-axis refers to front, the negative direction of the Y-axis refers to back, the positive direction of the X-axis refers to left, and the negative direction of the X-axis refers to right.

[0037] Embodiments of the present invention provide a display and control console 100, such as Figure 1 As shown, the system includes an interconnected control panel 110 and a base 120. The control panel 110 has an operating area 200, which serves as the working space for a keyboard support 210. The keyboard support 210 includes several operation keys 211. On one hand, the operation keys of the keyboard support 210 can be adapted to specific buttons to meet specific operating environments. For example, these specific buttons could be remote control switches, emergency light switches, or other similar operation buttons. On the other hand, in this embodiment, the angle of the keyboard support 210 can be adjusted to move the operation keys 211 to suitable positions to accommodate the operator's habits. In specific implementations, multiple operation keys 211 can be selectively arranged in rows, columns, or other configurations.

[0038] Specifically, in this embodiment, the keyboard support 210 includes a base 220, with an operating area on the top of the base 220, and operating keys 211 disposed on the upper surface of the base 220. It should be noted that in this embodiment, the base 220 can be adjusted by adjusting the adjustment component 230 to completely remove the keyboard support 210 from the surface of the operating table 110, or the base 220 can always be positioned within the operating area 200 of the operating table 110, as long as it meets the operational needs.

[0039] In some embodiments of this application, the bottom of the base 220 is provided with a plurality of adjustment components 230 for supporting the base 220. The adjustment components 230 include a gear 232, a first rack 2321, a second rack 2322, and a support shaft 231. The first end 2311 of the support shaft is rotatably connected to a predetermined position of the base 220, and the second end 2312 of the support shaft is rotatably connected to the gear 232. The gear 232 meshes with the first rack 2321 and the second rack 2322. The gear 232 can move along the first rack 2321 and the second rack 2322. When the gear 232 moves, it can drive the first end 2311 of the support shaft to be raised or lowered.

[0040] This application provides an adjustment component 230 for supporting the base 220 at its bottom. The adjustment component 230 further includes a gear 232, a first rack 2321, a second rack 2322, and a support shaft 231 that are interconnected. When the angle or position of the keyboard bracket needs adjustment, one of the first rack 2321 and the second rack 2322 drives the gear 232 to roll along the extension direction of the first rack 2321 and the second rack 2322. Simultaneously, during the rolling process, the gear 232 drives the support shaft 231 to oscillate, causing the angle of the base 220 to change accordingly, thereby achieving the purpose of adjusting the keyboard bracket. When multiple adjustment components 230 are provided at the bottom of the base 220, the base 220 can have more possibilities for angle and position adjustment, better meeting the angle adjustment needs under various requirements, especially better meeting the adjustment needs of instruments or dashboards such as special vehicle display consoles in different environments (especially in mountainous environments).

[0041] In addition, by including a gear 232, a first rack 2321, and a second rack 2322 in the adjustment component 230, the locking function of the base 220 can be well realized when the gear 232 is relatively stationary with the first rack 2321 and the second rack 2322 under the meshing of the gear 232, the first rack 2321, and the second rack 2322. This makes the keyboard bracket more stable after the angle and position are adjusted, and can better meet the keyboard operation needs of instruments or dashboards such as special vehicle display consoles in complex working environments.

[0042] It should be noted that the number of adjustment components 230 used to support the base 220 is not specifically limited; in specific implementations, there may be one, two, three, four, or more than five. In specific implementations, the keyboard bracket 210 may also selectively include other support structures for supporting the base 220; for example, the keyboard bracket 210 may include a support column (not shown in the figure), with one end of the support column fixedly connected to the operating table 110, and the other end of the support column ball-jointed to the central area of ​​the lower surface of the base 220, and the adjustment component 230 connected to an area outside the central area of ​​the lower surface of the base 220 via the first end 2311 of the support shaft.

[0043] It should be explained that the "predetermined position of the base" in this application refers to a position on the base for connection with the support shaft and for raising or lowering as the support shaft moves. For example, the predetermined position can be the lower surface of the base or the side wall of the base. When the keyboard bracket includes multiple adjustment components, the predetermined position can be selectively set to an area on the lower surface of the base other than the geometric center.

[0044] In some preferred embodiments of this application, the base 220 has four adjustment components 230 at its bottom. In this embodiment, the base 220 is generally square, and the adjustment components 230 are distributed below the four corners of the base 220 to adjust the height of the four corners, thereby achieving multi-degree-of-freedom adjustment of the base 220 as a whole, allowing the base 220 to reach different positions. It should be noted that the structural form of the base 220 is not specifically limited. In specific implementations, the base 220 can also be selectively arranged in a circular shape.

[0045] For a single adjustment component 230, the adjustment component 230 includes a gear 232, a first rack 2321, a second rack 2322, and a support shaft 231. The first end 2311 of the support shaft is rotatably connected to a predetermined position on the base 220, and the second end 2312 of the support shaft is rotatably connected to the gear 232. The gear 232 meshes with the first rack 2321 and the second rack 2322. The gear 232 rotates along the first rack 2321 and the second rack 2322 to achieve displacement. In specific implementation, the first rack 2321 is further fixed to the operating area 200 of the operating table 110 (i.e., the side wall of the display and control console 100), and the second rack 2322 can slide relative to the operating table 110. Under the drive of the second rack 2322, the gear 232 meshing with it rotates and displaces, thereby causing the second end 2312 of the support shaft to move horizontally, and causing the first end 2311 of the support shaft to swing, so as to raise or lower the corresponding position of the base 220. At this time, if the other adjustment components 230 are kept still, that is, if the other positions of the base 220 remain unchanged, the first end 2311 of the support shaft changes in height due to the position change of the second end 2312 of the support shaft, referring to... Figure 3-4 In contrast Figure 1-2 The first end 2311 of the support shaft is lifted, thereby causing the keyboard bracket 210 to rise at that position, thus changing the overall position of the keyboard bracket 210.

[0046] In some embodiments of this application, both the first rack 2321 and the second rack 2322 are further configured as straight racks, and both the first rack 2321 and the second rack 2322 extend in the horizontal direction. The first rack 2321 is fixed to the side wall of the display console 100, for example, the side wall surface of the first rack 2321 is fixed to the side wall of the display console 100. The second rack 2322 can move in the horizontal direction. The adjustment component 230 is configured such that when the second rack 2322 moves in the horizontal direction, the gear 232 drives the second end 2312 of the support shaft to move in the horizontal direction, and the first end 2311 of the support shaft swings around the second end 2312 of the support shaft. During the swinging process of the first end 2311 of the support shaft around the second end 2312 of the support shaft, the position of the base 220 is adjusted.

[0047] In other embodiments, the base 220 is further selectively made into a square structure, the keyboard bracket 210 includes four adjustment components 230, the base 220 includes a first side and a second side opposite to the first side; two adjustment components 230 are provided below the first side and below the second side respectively, the second racks 2322 included in the two adjustment components 230 below the first side are collinearly arranged, the second racks 2322 included in the two adjustment components 230 below the second side are collinearly arranged, and the two second racks 2322 below the first side and the two second racks 2322 below the second side are arranged parallel to each other.

[0048] Reference Figure 5 A groove 240 extending along the movement direction of the second rack 2322 is provided on the outer wall of the entire operating area 200. A protrusion 241 is provided on the second rack 2322, extending from the inner side of the groove 240 and capable of sliding along the groove 240. In a specific implementation, the groove 240 is a through groove penetrating the side wall of the operating area 200, and the protrusion 241 at least partially protrudes from the groove 240, so that the protrusion 241 is at least partially located on the outer side of the operating area 200. The portion of the protrusion 241 located on the inner side of the groove 240 is fixedly connected to the second rack 2322, thereby allowing the second rack 2322 to be directly controlled from the outside by the portion of the protrusion 241 located on the outer side of the operating area 200, and also allowing the movement trajectory of the second rack 2322 to extend along the direction of the groove 240.

[0049] Furthermore, in some other embodiments, the protrusion 241 is provided with a positioning hole, and a plurality of limiting holes are distributed along the surface of the slide groove 240. When the protrusion 241 reaches the predetermined position, one end of the positioning pin can be inserted into the positioning hole, and the other end can be inserted into the limiting hole, thereby limiting the relative position of the protrusion 241 and the slide groove 240, thereby achieving the limiting of the second rack 2322.

[0050] In other embodiments, a spring pin is provided on the protrusion 241. When the protrusion 241 reaches the predetermined position, the spring pin pops out and abuts and locks inside the slide groove 240, thereby limiting the relative position of the protrusion 241 and the slide groove 240, and thus achieving the limiting of the second rack 2322.

[0051] In an implementation that includes multiple adjustment components 230, one adjustment component 230 can be adjusted individually or multiple adjustment components 230 can be adjusted simultaneously so that the keyboard support 210 can achieve multiple positional states. That is, both the spatial position and the posture can be adjusted, thereby giving the keyboard support 210 better adaptability.

[0052] In this embodiment, when adjustment is required, the following steps are taken: adjust at least one adjustment component (optionally, lock other adjustment components at the same time) so that a specific position of the keyboard support 210 reaches a predetermined height, thereby changing the overall posture of the keyboard support 210.

[0053] After prolonged use of the control panel 110, dust or debris will inevitably accumulate in the control area 200, especially near the control buttons 211. Some dust and debris can easily obstruct or hinder the operation of the control buttons 211. In some cases, cleaning the control buttons 211 requires specific cleaning tools; otherwise, accidental activation of the control buttons 211 may occur.

[0054] Reference Figures 6 to 7 , Figure 7 yes Figure 3 A partially enlarged view of the structure at point C shows that, in this embodiment, the keyboard support 210 is provided with multiple receiving slots 250, and correspondingly, multiple cleaning components 260 are provided. Specifically, the receiving slot 250 includes a first inclined surface 251 and a second inclined surface 252. When the keyboard support 210 is in a horizontal state, the receiving slot 250 is recessed vertically downward along the upper surface of the keyboard support 210, so that the receiving slot 250 is located entirely below the vertical direction of the operation keys, allowing dust or debris to fall naturally into the bottom of the slot under the action of gravity.

[0055] It should be noted that the height of each corresponding position of the keyboard stand 210 can be adjusted by adjusting component 230. This not only changes the angle of the keyboard stand 210 to achieve various tilting and deflection postures, but also causes the keyboard stand 210 to shake, so that accumulated dust or debris falls into the receiving groove 250. That is, whether in a natural state or through movement, the receiving groove 250 can collect dust or debris.

[0056] After the receiving tank 250 collects dust or debris, it generally accumulates at the bottom of the tank under gravity. The cleaning component 260 includes a retractable suction tube 261, whose suction port can move along the bottom of the receiving tank 250 to suck away the dust and debris. In specific implementations, the cleaning component 260 also includes a drive component 262 that controls the extension and retraction of the suction tube 261. In one embodiment, a linear motor can be selected to directly drive the movement of the suction tube 261's opening, in which case the suction tube 261 is configured as a flexible tube. Alternatively, the drive component 262 can selectively include a telescopic unit (e.g., a cylinder or hydraulic cylinder) or a lead screw and slider assembly. It is understood that the drive assembly 262 is installed within the operating area 200. The drive end of the drive assembly 262 can move along the length of the receiving groove 250. The drive end of the drive assembly 262 is connected to the suction port of the suction pipe 261. When the drive end of the drive assembly 262 moves within the receiving groove 250, it can drive the suction port of the suction pipe 261 to move within the receiving groove 250. A suction pump is provided at the end of the suction pipe 261 (i.e., the end away from the suction port). When the suction pump is working, it can generate suction, thereby sucking away the dust in the receiving groove 250 through the suction pipe 261.

[0057] In this embodiment, the receiving groove 250 extends in a straight line to facilitate the suction tube 261 to suck away dust and debris.

[0058] In other embodiments, the suction tube 261 is configured as a polygonal structure that matches the shape of the tank bottom to achieve thorough cleaning of dust or debris at the bottom of the tank.

[0059] In other embodiments, the slope length of the first inclined plane 251 is greater than the slope length of the second inclined plane 252, and the slope of the first inclined plane 251 is less than the slope of the second inclined plane 252.

[0060] It should be noted that the receiving slots 250 are not only arranged horizontally along the direction shown in the figure. In other embodiments, multiple receiving slots 250 and corresponding cleaning components 260 are also provided along the longitudinal direction.

[0061] In this embodiment, the following steps are taken when cleaning is required:

[0062] Step S1: Adjust multiple adjustment components 230 so that dust and debris near the operation key 211 fall into the receiving slot 250 under the action of gravity;

[0063] Step S2: Control the suction tube 261 to move along the bottom of the receiving tank 250, thereby sucking away the dust and debris that fall into the receiving tank 250.

[0064] In this embodiment, not all dust or debris will fall to the bottom of the receiving groove 250. Most of the dust and debris will accumulate at the bottom of the receiving groove 250, and some of the dust and debris will adhere to the groove wall of the receiving groove 250. Therefore, in order to ensure a better cleaning effect, a replaceable storage strip 253 is added. The storage strip 253 is laid at the bottom of the receiving groove 250 and is set along the extension direction of the receiving groove 250.

[0065] In this embodiment, the storage strap 253 includes a continuous first segment and a second segment. The first segment covers the bottom of the receiving groove 250, and the second segment extends and flips to the back of the keyboard bracket 210. The storage strap 253 can move along the receiving groove 250 to gradually switch the first segment covering the receiving groove 250 to the second segment, thus realizing the replacement of the storage strap 253. This allows the dust and debris attached to the first segment to flip to the back of the keyboard bracket 210 and fall off under the action of gravity. In this embodiment, a storage compartment (not shown in the figure) is also provided at the bottom of the operating area 200. The storage compartment can collect the dust and debris that fall from the back of the keyboard bracket 210.

[0066] In this embodiment, the storage strip 253 covers part of the surface of the receiving groove 250. This is because the movement of the storage strip 253 will objectively cause dust and debris to move. If the entire surface of the receiving groove 250 is covered, some dust and debris may return to the vicinity of the operation key 211. However, since the storage strip 253 covers part of the surface of the receiving groove 250, even if some dust and debris move, they will only accumulate at the edge of the storage strip 253 and remain inside the receiving groove 250.

[0067] In other embodiments, the receiving strip 253 covers the entire surface of the receiving groove 250.

[0068] In other embodiments, the surface of the storage strip 253 is adhesive, which can attract dust and debris.

[0069] This embodiment has been further optimized, referring to... Figure 8 As mentioned above, most of the dust and debris accumulates at the bottom of the receiving groove 250, while some adheres to the groove wall. With the collection strap 253 installed, some of the dust and debris adheres to the collection strap 253, while the remaining dust and debris often stays at the edge 254 of the collection strap. Therefore, in this embodiment, the suction tube 261 is further optimized. Figure 8 A schematic diagram of the suction port of the suction tube 261 is shown. A first baffle 2611 and a second baffle 2612 are provided at the suction port of the suction tube 261. The first baffle 2611 and the second baffle 2612 can rotate around the suction port of the suction tube 261. It can be understood that one end of the first baffle 2611 and the second baffle 2612 is hinged to a connecting ring (not shown in the figure). The connecting ring is fitted at the suction port of the suction tube 261. The ends of the first baffle 2611 and the second baffle 2612 away from the connecting ring can move radially towards both sides of the suction port, thereby realizing the rotation of the first baffle 2611 and the second baffle 2612 around the suction port.

[0070] Please refer to this section. Figure 9 , Figure 9 yes Figure 6 An enlarged view of region D should be provided. Figure 7 In this state, the suction tube 261 is still in its initial state. Figure 9 In the middle, the storage belt 253 has a first slot 2531 and a second slot 2532 on the side away from the suction port of the suction tube 261, which correspond to the first baffle 2611 and the second baffle 2612 respectively. When the suction port of the suction tube 261 reaches the corresponding position of the first slot 2531 and the second slot 2532, such as Figure 10As shown, the first baffle 2611 and the second baffle 2612 can be opened manually. That is, the first baffle 2611 and the second baffle 2612 open radially from the axial direction of the suction tube 261 to both sides of the suction tube 261, thereby respectively engaging with the first slot 2531 and the second slot 2532. The first baffle 2611 and the second baffle 2612 respectively pass over the edges of the storage strap 253 on the first inclined surface 251 and the second inclined surface 252, as shown in the specific reference. Figure 10 , Figure 10 yes Figure 9 The diagram shows the structure of area aa with the suction tube 261 in the engaged state. The first baffle 2611 and the second baffle 2612 of the suction tube 261 are open and respectively engaged in the first slot 2531 and the second slot 2532. At this time, if the suction tube 261 is pulled back to the initial position, the first baffle 2611 and the second baffle 2612 are limited by the first slot 2531 and the second slot 2532, which causes them to drive the collection belt 253 to move. Thus, on the one hand, the collection belt 253 is switched; on the other hand, the first baffle 2611 and the second baffle 2612 respectively cover the edges of the collection belt 253 on the first slope 251 and the second slope 252, so that the first baffle 2611 and the second baffle 2612 can carry the dust and debris located at the edge of the collection belt 253 into the collection belt 253 or carry it to the area without the operation button 211, thereby further achieving the cleaning purpose.

[0071] It should be noted that, in order to achieve better cleaning results, the first baffle 2611 is adapted to the shape of the storage band 253 on the first inclined surface 251, and the second baffle 2612 is adapted to the shape of the storage band 253 on the second inclined surface 252. After the first baffle 2611 and the second baffle 2612 are opened, at least one side of the first baffle 2611 and the second baffle 2612 is in close contact with the groove surface of the receiving groove 250.

[0072] In this embodiment, when a complete and thorough cleaning is required, the following operating steps are adopted:

[0073] Step S1: Adjust multiple adjustment components 230 so that dust and debris near the operation key 211 fall into the receiving slot 250 under the action of gravity, and most of them fall into the storage strip 253;

[0074] Step S2: Control the suction port of the suction tube 261 to move along the bottom of the receiving groove 250 to suck away the dust and debris at the bottom of the receiving groove 250.

[0075] Step S3: Pull the storage belt 253 to move it along the extension direction of the receiving groove 250, and the dust and debris attached to its surface are carried away from the area of ​​the receiving groove 250.

[0076] Furthermore, in conjunction with the first baffle 2611 and the second baffle 2612, the following steps may also be included before step S3 (i.e., step S2):

[0077] Step S21: When the suction tube 261 reaches the predetermined position, the first baffle 2611 and the second baffle 2612 of the suction port are opened, so that the first baffle 2611 and the second baffle 2612 are inserted into the corresponding slots of the storage strip 253.

[0078] Step S22: Move the suction tube 261 to the initial state. The first baffle 2611 and the second baffle 2612 drive the storage belt 253 to move, and remove the dust and debris in the area covered by the baffles from the keyboard area.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

1. A keyboard stand for use on a display console, characterized in that, The keyboard support includes a base, an operating area on the top of the base with several operating keys, and several adjustment components at the bottom of the base for supporting the base. Each adjustment component includes a gear, a first rack, a second rack, and a support shaft. A first end of the support shaft is rotatably connected to a predetermined position on the base, and a second end of the support shaft is rotatably connected to the gear. The gear meshes with the first rack and the second rack. The gear can move along the first rack and the second rack, and when the gear moves, it causes the first end of the support shaft to rise or fall. Both the first rack and the second rack extend in the horizontal direction. The first rack is fixed to the side wall of the display console, and the second rack can move in the horizontal direction. The adjustment component is configured such that when the second rack moves in the horizontal direction, the gear meshing with the second rack rotates and is displaced. The gear drives the second end of the support shaft to move in the horizontal direction, and the first end of the support shaft swings around the second end of the support shaft. The outer wall of the operating area is provided with a groove extending along the movement direction of the second rack. The second rack is provided with a protrusion that extends from the inner side of the groove and can slide along the groove. The groove is a through groove that passes through the side wall of the operating area. The protrusion at least partially protrudes from the groove so that at least part of the protrusion is located outside the operating area. The part of the protrusion located inside the groove is fixedly connected to the second rack, so that the second rack can be directly controlled from the outside by the part of the protrusion located outside the operating area. At the same time, the movement trajectory of the second rack extends along the direction of the groove. The protrusion is provided with a positioning hole, and a plurality of limiting holes are distributed along the surface of the groove.
