Description

Technical Field

[0001] This utility model relates to office equipment, and more specifically, to an electric height-adjustable desk. Background Technology

[0002] As people spend more and more time sitting at work, they gradually realize that prolonged sitting is actually detrimental to improving work efficiency. People have begun to try alternating between sitting and standing while working, and gradually, height-adjustable desks have emerged. Using height-adjustable desks for standing work has become a popular and healthy way of working.

[0003] Currently available height-adjustable desks can be broadly categorized by their height adjustment mechanism into: automatic height-adjustable desks, manual height-adjustable desks, and desktop height-adjustable desks. Automatic height-adjustable desks typically use electricity as their power source, with an electric motor controlling a mechanical device to adjust the desk's height. Manual height-adjustable desks, on the other hand, are more traditional, requiring manual adjustment of the mechanical structure, hydraulic rods, or pneumatic rods to achieve height adjustment.

[0004] Among them, the desktop height-adjustable desk, which is applied to the desktop of the traditional office desk, can achieve the same effect as the height-adjustable desk, making it convenient for people to switch between standing and sitting office. At present, desktop height-adjustable desks on the market usually use gas springs to achieve manual height adjustment, which makes up for the shortcomings of existing office desks that cannot meet the height adjustment. However, the gas spring method has the problems of inconvenience in adjustment and low adjustment precision. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric height-adjustable table.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an electric height-adjustable desk, comprising:

[0007] Support frame;

[0008] The height-adjustable table is connected to the supporting base frame via a scissor-type lifting assembly.

[0009] The scissor lift assembly is connected between the support base and the lifting table. The ends of the two sliding ends of the scissor lift assembly are slidably connected to the support base and the lifting table, respectively. The support base and the lifting table are provided with guide frames for the sliding ends to slide. The sliding end of the scissor lift assembly is provided with a damping structure that slides within the guide frame to provide damping force for the displacement of the sliding end of the scissor lift assembly.

[0010] The present invention is further configured such that: the scissor lift assembly includes two sets of first hinge arms and second hinge arms, the middle parts of the first hinge arms and the second hinge arms are hinged to each other, the first hinge arms and the second hinge arms are respectively hinged to the support base and the lifting table on the same side, and the other ends of the first hinge arms and the second hinge arms are slidably connected to the guide frame through a damping structure.

[0011] The present invention is further configured such that: the damping structure includes a rotating pin and a damping block, the damping block has a polygonal cross-section, and the outer surface of the damping block is in contact with the inner wall of the guide frame.

[0012] The present invention is further configured such that: a plurality of damping ridges are distributed in a ring array on the outer surface of the damping block, and the length direction of the damping ridges is perpendicular to the length direction of the guide frame.

[0013] The present invention is further configured such that: the scissor lift assembly further includes an electric push rod, the fixed end of the electric push rod is hinged between two first hinged arms, and the telescopic end of the electric push rod is hinged to two second hinged arms through a hinge rod.

[0014] The present invention is further configured such that: the damping block located on the second hinge arm has a cross-section of a regular octagon, and each side of the damping block is provided with at least two damping ridges.

[0015] The present invention is further configured such that: the lifting table includes a supporting table and a keyboard tray, the keyboard tray is fixedly connected to the bottom surface of the supporting table through a bridge frame, and a lifting controller is fixedly connected to the bottom of the supporting table.

[0016] The present invention is further configured such that: a wireless charging module is provided on the supporting table, and the wireless charging module is connected in parallel with the lifting controller.

[0017] The present invention is further configured such that: a long groove is provided on the support table, and a cable management box is detachably connected to the support table, and the cable management box is provided with a plurality of through holes for accommodating cable bundles.

[0018] In summary, this utility model has the following beneficial effects:

[0019] This application incorporates a damping structure on the scissor lift assembly between the support base and the lifting table, which, in conjunction with the guide frame on the support base and the lifting table, increases the damping force of the scissor lift assembly. This replaces the gas spring method commonly used in the market, allowing for both electric height adjustment and increased damping force between the scissor lift assembly and the guide frame. This ensures good support stability when placing hardware devices such as laptops, monitors, and keyboards on the lifting table.

[0020] The damping structure in this application consists of a rotating pin and damping blocks. The damping blocks on the first and second hinge arms have octagonal and quadrilateral cross-sections, respectively. When the electric push rod extends, it pushes the hinge rod to deflect the two second hinge arms. At this time, the horizontal height of the damping blocks on the second hinge arms changes and they are displaced along the length of the guide frame, exhibiting an arc-shaped trajectory. The octagonal damping blocks have a greater chance of flipping when driven by the electric push rod, thus facilitating the movement of the second hinge arms. The damping blocks on the first hinge arm have a square structure, which is less prone to deflection than the octagonal blocks, thereby increasing the sliding damping between the first hinge arm and the guide frame. After adjustment to the specified height, it can play a good anti-slip role and maintain the adjustment accuracy.

[0021] Damping ridges are provided on the damping blocks, and the length direction of the damping ridges is perpendicular to the length direction of the guide frame, so that there is a large damping friction force between the damping blocks and the guide frame, which restricts the sliding deviation of the first scissor arm or the second scissor arm.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 and Figure 3As shown, the electric height-adjustable desk includes: a support base 1, a height-adjustable tabletop 2, and a scissor-type lifting assembly 3 disposed between the support base 1 and the height-adjustable tabletop 2. The ends of the lifting assembly on the same vertical side are hinged to the support base and the height-adjustable tabletop 2 respectively via hinge seats, and the ends on the other vertical side are slidably connected to the support base and the height-adjustable tabletop 2 respectively. Specifically, in this embodiment, four guide frames 4 are fixedly connected to the support base 1 and the height-adjustable tabletop 2 by screws. Furthermore, the sliding end of the scissor-type lifting assembly 3 is provided with a damping structure that slides within the guide frames 4, which provides a damping force to resist displacement when the sliding end of the scissor-type lifting assembly 3 moves within the guide frames 4.

[0029] like Figure 2 and Figure 3 As shown, the scissor lift assembly 3 includes two sets of first hinge arms 31 and second hinge arms 32. The middle parts of the first hinge arms 31 and the second hinge arms 32 are hinged to each other. In this embodiment, the two second hinge arms 32 are located between the two first hinge arms 31. The first hinge arms 31 and the second hinge arms 32 on the same side are respectively hinged to the support base 1 and the lifting table 2. The other ends of the first hinge arms 31 and the second hinge arms 32 are slidably connected to the guide frame 4 through a damping structure. In this embodiment, the sliding end of the second hinge arm 32 located on the inner side is slidably connected to the lifting table 2 through the guide frame 4 and the damping assembly. The first hinge arm 31 located on the outer side is slidably connected to the support base 1 through the guide frame 4. A synchronous rod is fixedly connected between the sliding ends of the two first hinge arms 31. An electric push rod 33 is rotatably connected to the synchronous rod. When the electric push rod 33 extends or retracts, the angle between the first hinge arms 31 and the second hinge arms 32 is adjusted to realize the lifting and lowering of the lifting table 2.

[0030] like Figure 3 and Figure 4As shown, the damping structure includes a rotating pin 5 and a damping block 6. The damping block 6 has a polygonal cross-section, and its outer surface is in contact with the inner wall of the guide frame 4. Furthermore, a plurality of damping ridges 7 are arranged in a circular array on the outer surface of the damping block 6. The length direction of the damping ridges 7 is perpendicular to the length direction of the guide frame 4. In this embodiment, the damping block 6 located on the second hinge arm 32 has a regular octagonal cross-section, and each side of the damping block 6 is provided with at least two damping ridges 7. The damping block 6 located on the first hinge arm 31... The damping block 6 is rectangular, and the damping block 6 on the first hinge arm 31 is attached to the inner wall of the guide frame 4. Each surface of the damping block 6 is provided with at least two damping ridges 7. The damping ridges 7 and the damping block 6 are made of polyurethane and are a single piece. During installation, the damping block 6 deforms to make the surfaces of the damping ridges 7 and the damping block 6 adhere tightly to the surface of the guide frame 4. Thus, under the deformation and compression force of the damping ridges 7 and the damping block 6, the sliding damping force of the first hinge arm 31 and the second hinge arm 32 is increased. When the electric push rod 33 drives the lifting table 2 to rise, although the increased damping force increases the resistance of the extension and retraction of the electric push rod 33, it also enables a slower and smoother adjustment when the lifting table 2 is raised and lowered, facilitating height adjustment. At the same time, the increased damping force also provides good stability when items are placed on the lifting table 2.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the lifting table 2 includes a supporting table 21 and a keyboard tray 22. The keyboard tray 22 is fixedly connected to the bottom surface of the supporting table 21 via a bridging frame 23. A lifting controller 24 is fixedly connected to the bottom of the supporting table 21. The bridging frame 23 adopts a Z-shaped or arched structure, and both ends of the bridging frame 23 are fixedly connected to the supporting table 21 and the keyboard tray 22 via screws. The bridging frame 23 is in the form of a thin sheet, and the bridging frame 23 has staggered hollow parts to further reduce the load and provide basic support connection strength. Several L-shaped pieces are fixedly connected to the side of the keyboard tray 22 located under the supporting table 21 to limit the keyboard position. The support tabletop 21 is equipped with a wireless charging module 8, which is connected in parallel with the lifting controller 24. By setting the wireless charging module 8, wireless charging of smart devices such as mobile phones can be achieved. The support tabletop 21 also has a long slot, and a cable management box 9 is detachably connected to the support tabletop 21. The cable management box 9 has several through holes to accommodate wires, so that wired keyboards, mice and other hardware can be connected to devices such as monitors or laptops through the through holes of the cable management box 9, and the mess of wires on the desktop can be avoided.
