Description

Technical Field

[0001] This utility model relates to a display stand, specifically to a display stand with automatic height adjustment. Background Technology

[0002] Whether in an office or at home, a desk is used when operating a monitor. Different people have different needs for desktop height, and desks with a fixed height cannot meet the needs of different users. Therefore, height-adjustable automatic height desks have been introduced to the market. However, these automatic height desks not only have complex mechanisms, but also cannot adaptively adjust according to changes in the user's height.

[0003] For example, in the prior art, Chinese utility model patent with publication number CN201528820U discloses an automatic monitor lifting and swinging desk, which includes a desktop, a desk body, a monitor clamping device, an automatic lifting and swinging device, and a control device; the desktop has a monitor protrusion opening, the lower part of the desktop is fixedly connected to the desk body, the lower part of the monitor clamping device that can fix the monitor is mounted on the automatic lifting and swinging device and can adjust the height position and tilt angle, the upper part of the monitor clamping device extends above the desktop through the monitor protrusion opening and can be moved down to the bottom of the desktop to be retracted.

[0004] The aforementioned patent allows for height adjustment of the display via buttons. Its adjustment principle is as follows: the program control cabinet starts the lifting box motor, which drives the lifting box worm gear and worm wheel, causing the wire rope wheel to rotate. This pulls the wire rope, which, through the wire rope clamp, raises the automatic swing box of the display. The automatic swing box moves upward along the track via rollers on both sides until it reaches the position of the upper lifting sensor switch. The lifting sensor switch then sends a signal, stopping the lifting box motor. However, the lifting device in this patent is not only complex in structure and bulky, but also cannot adaptively adjust according to the user's height. Therefore, this utility model proposes a display stand that can automatically adjust its height according to the user's height. Utility Model Content

[0005] This invention aims to solve the problem that existing desks cannot adaptively adjust their height according to the user's height, and proposes an automatically height-adjustable monitor stand that can adaptively adjust the desktop height according to the user's height, thereby improving the user's experience and convenience.

[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows:

[0007] An automatically height-adjustable display stand includes an operating surface, a base supporting the operating surface, and a lifting device disposed between the operating surface and the base. The operating surface is provided with a position sensor for detecting the current user's height, a control box connected to the position sensor, and a start / stop control button connected to the control box. The lifting device includes a power unit and a lifting mechanism connected thereto. The control box is connected to the power unit, receives signals from the position sensor and the start / stop control button, and outputs corresponding control commands to the power unit.

[0008] Furthermore, two bases are provided below the operating table, and a lifting housing is movably connected to the base. The top of the lifting housing is fixedly connected to the bottom of the operating table, and two lifting mechanisms are provided, which are respectively located in the left and right lifting housings.

[0009] Furthermore, the operating platform has a cavity inside, and the power unit is fixedly installed in the cavity, located between the left and right lifting mechanisms. The lifting mechanism includes a rack fixedly connected to the base and a traveling gear meshing with the rack. A transmission shaft is provided on one side of the power unit, and the transmission shaft is connected to the output end of the servo motor. The two ends of the transmission shaft are respectively connected to the traveling gear in the lifting mechanism.

[0010] Furthermore, the traveling gear is rotatably mounted on a gear mounting bracket, which is fixedly connected to the operating table surface.

[0011] Furthermore, the bottom of the control panel is provided with an opening that allows the top of the rack to pass through.

[0012] Furthermore, two bearing seats for mounting the traveling gear are provided below the gear mounting bracket. The opposing sides of these two bearing seats are engaged with the left and right sides of the non-meshing surface of the rack to provide guidance.

[0013] Furthermore, the lifting housing, operating table, gear mounting bracket, and traveling gear form a whole and are securely fitted to the outside of the rack.

[0014] Furthermore, the operating table surface is provided with multiple snap-fit ​​components for fixing the display, each snap-fit ​​component including a snap-fit ​​part and a detachable locking part.

[0015] Furthermore, two position sensors are provided and distributed on the left and right sides directly in front of the user's seat.

[0037] Example 1

[0038] As the most basic embodiment of this utility model, such as Figure 1 and Figure 2 As shown, this utility model provides an automatically height-adjustable display stand, including an operating surface 1, a base 2 supporting the operating surface 1, and a lifting device disposed between the operating surface 1 and the base 2. The operating surface 1 is equipped with a position sensor 12 for detecting the current user's height, a control box connected to the position sensor 12, and a start / stop control button connected to the control box. Two position sensors 12 are provided and distributed on the left and right sides directly in front of the user's seat. The control box is also connected to the power unit in the lifting device, receiving signals from the position sensors 12 and the start / stop control button, and outputting corresponding control commands to the power unit in the lifting device.

[0039] The position sensor 12, control box, and power unit are all connected to the power supply 11 via signal line 13.

[0040] Specifically, in this solution, the lifting device includes a power unit and a lifting mechanism 3 connected thereto. Preferably, the power unit is a servo motor 4. The start / stop control button is a "lock / unlock button," which can also work with an indicator light to show whether the lifting table is currently unlocked or locked. The control box receives the signal from the start / stop control button and outputs start / stop control commands to the servo motor 4. The position sensor 12 detects the current user's height and sends the signal to the control box. The control box receives and processes the signal and then outputs commands to the servo motor 4 to control the lifting mechanism 3 to rise or fall.

[0041] Preferably, in this solution, the position sensor 12 uses an IX series multi-point laser sensor. Multi-point laser sensors are mature sensors used in industry. Their detection principle mainly involves image recognition via a camera, tracking a designated point, and using laser light to measure the height and height difference of that point. The IX series multi-point laser sensor can measure the user's current height.

[0042] The workflow of this utility model is as follows:

[0043] Before use, the monitor stand is locked. After the user sits down in front of the monitor stand, they click the "Unlock" button on the operating panel 1. The position sensor 12 detects the user's current height and sends the detection signal to the control box. The control box compares and calculates the height with the previously recorded height and then outputs a control command to the servo motor 4, which drives the lifting mechanism 3 to adjust the height to match the user's current height. After adjustment, the user clicks the "Lock" button on the operating panel 1. Alternatively, the monitor stand can automatically lock after each adjustment, and the next adjustment can begin when the user presses the "Unlock" button.

[0044] This utility model's display stand can adaptively adjust according to the user's height, improving the user experience and convenience. The height of the display stand changes depending on the user's height and posture, such as changing from a sitting to a reclining or standing position. After pressing the control button, the height of the display stand can be readjusted according to the user's current posture.

[0045] Example 2

[0046] As a preferred embodiment of the present invention, this embodiment provides an automatically height-adjustable display stand. Unlike embodiment 1, this embodiment further limits the lifting device used.

[0047] There are many existing lifting devices, such as screw jacks, hydraulic jacks, and telescopic electric cylinders, all of which can be used in this solution. However, considering factors such as floor space, lifting efficiency, and lifting accuracy, this embodiment provides a solution such as... Figure 4 The lifting device shown is a gear and rack structure 6.

[0048] To improve lifting stability, two bases 2 are provided below the operating platform 1, and a lifting housing 9 is movably connected to the base 2. The top of the lifting housing 9 is fixedly connected to the bottom of the operating platform 1. Two lifting mechanisms 3 are provided, one in each of the left and right lifting housings 9. Specifically, in this design, the lifting mechanism 3 includes a rack 6 fixedly connected to the base 2 and a traveling gear 7 meshing with the rack 6.

[0049] like Figure 3As shown, the operating platform 1 has an internal cavity, and the power unit of the lifting device is fixedly installed in this cavity, located between the left and right lifting mechanisms 3. The power unit is a servo motor 4, with a drive shaft 5 on one side. The drive shaft 5 is rotatably connected to two bearings 16. The drive shaft 5 is connected to the output end of the servo motor 4 to achieve transmission; specifically, the two are connected by chain drive, synchronous toothed belt drive, or gear drive. The rotation of the servo motor 4 drives the drive shaft 5 to rotate in the bearings 16. The two ends of the drive shaft 5 are respectively connected to the traveling gears 7 in the two lifting mechanisms 3 to achieve transmission. Preferably, the drive shaft 5 and the traveling gear 7 can be connected by chain drive, synchronous toothed belt drive, or gear drive. Preferably, in this solution, the traveling gear 7 is an integral coaxial double-tooth structure, and the drive shaft 5 is connected to the gear on the side that is not meshed with the rack 6.

[0050] In this design, the traveling gear 7 is rotatably mounted on the gear mounting bracket 14, and an opening 17 is provided at the bottom of the operating table to allow the top of the lifting mechanism 3 to pass through. This opening 17 allows the upper end of the rack 6 to extend into the operating table surface 1, providing space for the operating table surface 1 to move up and down. The gear mounting bracket 14 passes through the opening 17 and is fixedly connected to the operating table surface 1. Two bearing seats 15 are provided below the gear mounting bracket 14, and the two ends of the traveling gear 7 are rotatably connected to the two bearing seats 15. The opposite sides of these two bearing seats 15 contact the left and right sides of the non-meshing surface of the rack 6, serving as a guide to restrict the traveling gear 7 to move only up and down along the rack 6.

[0051] In this design, the lifting housing 9 encloses the traveling gear 7 and the rack 6, and together with the traveling gear 7 and the gear mounting bracket 14, it is stably attached to the outside of the rack 6. This ensures that the entire assembly consisting of the lifting housing 9, the operating table 1, the gear mounting bracket 14, and the traveling gear 7 is stably connected to the rack 6, and can only move up and down in the vertical direction along the rack 6 under the drive of the power unit.

[0052] In this embodiment, the lifting device uses a servo motor 4, which drives two lifting mechanisms 3 to move synchronously via a transmission shaft 5. The transmission shaft 5 and the traveling gear 7 in the lifting mechanism 3 are driven by a chain, synchronous belt, or gear, resulting in relatively high transmission accuracy. The power unit of the lifting device is located inside the operating platform 1, and the lifting mechanism 3 is located inside the lifting housing 9, with no exposed complex structures, resulting in a simple structure and small footprint.

[0053] The working principle of the lifting device is as follows:

[0054] After receiving the control command from the control box, the servo motor 4 is activated, driving the transmission shaft 5 connected to it to rotate. The rotation of the transmission shaft 5 drives the walking gears 7 connected to both ends to rotate, causing the entire assembly consisting of the lifting housing 9, the operating table 1, the gear mounting bracket 14, and the walking gears 7 to move up and down in the vertical direction along the rack 6, thus realizing the synchronous lifting of the left and right lifting mechanisms 3.

[0055] Example 3

[0056] Based on Example 1 or Example 2, this example further improves as follows:

[0057] Furthermore, to improve the stability of the monitor during height adjustment, the operating surface 1 is provided with multiple latching components 10 for fixing the monitor. Each latching component 10 includes a locking element 101 and a detachable locking element 102. Preferably, the detachable locking element 102 is a bolt, and the operating surface 1 has corresponding screw holes. The locking element 101 is connected to the screw holes of the operating surface 1 by bolts. When the locking element 102 is not tightened, its position can be rotated and adjusted to match the position of the monitor base 2. After adjustment, the locking element 102 is locked to achieve fixation. In this solution, four sets of latching components 10 are provided, located around the monitor base 2.

[0058] It should be noted that all parts not described herein are implemented using existing technologies. Those skilled in the art can make adaptive adjustments to achieve the objectives of this invention.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
