Description

Technical Field

[0001] This application relates to the field of smart home, and in particular to an electric height-adjustable desk bracket and an electric height-adjustable desk. Background Technology

[0002] An electric height-adjustable desk is a type of desk whose desktop height can be adjusted as needed. It is convenient to use and widely used in homes, offices, and other places.

[0003] Electric height-adjustable desks typically have hooks attached to their sides for hanging objects. Common hook installation methods include adhesive and magnetic attachment, but both are prone to detachment. To make the hooks more secure, some electric height-adjustable desks use welded hooks.

[0004] Although welding provides high strength, the weld joint is usually not smooth, resulting in an uneven rust-proof layer when applied, such as with paint. Over time, this rust-proof layer is prone to peeling off, leading to rapid corrosion at the weld. Utility Model Content

[0005] This application provides an electric height-adjustable desk bracket and an electric height-adjustable desk, enabling the adjustment of the desk's dimensions for convenient use. The technical solution is as follows:

[0006] In a first aspect, embodiments of this application provide an electric height-adjustable desk bracket, which includes a desktop assembly and two support assemblies;

[0007] The desktop assembly includes two crossbeams and two longitudinal beam supports. The two crossbeams are arranged in parallel and spaced apart. The two longitudinal beam supports are respectively arranged at both ends of the crossbeams, and each longitudinal beam support is connected to the two crossbeams.

[0008] The longitudinal beam support arm includes a top plate, a side plate, and a first hook. The top plate is connected to the cross beam, one side of the side plate is connected to one side of the top plate, and the first hook is connected to the other side of the side plate away from the top plate. The top plate, the side plate, and the first hook are an integrated structural component.

[0009] The two support components are located at the two ends of the crossbeam, and each support component includes a lifting leg and a housing. The housing is located at the top of the lifting leg and connected to the lifting leg. The housing is located between the two crossbeams and connected to the crossbeam.

[0010] In some examples, the first hook includes a first straight portion, a second straight portion, and a third straight portion. One end of the first straight portion is connected to the side plate. The first straight portion, the second straight portion, and the third straight portion are connected in sequence. The lines of intersection of the first straight portion and the second straight portion, the lines of intersection of the second straight portion and the third straight portion, and the lines of intersection of the side plate and the top plate are parallel to each other.

[0011] In some examples, the side plate is perpendicular to the top plate, the first straight portion is perpendicular to the second straight portion, and the third straight portion is perpendicular to the second straight portion.

[0012] In some examples, the desktop assembly further includes a connecting beam and a second hook, the connecting beam being connected to the top surfaces of the two crossbeams respectively, the second hook being located between the two crossbeams and on the side of the connecting beam closer to the crossbeams, and the second hook being connected to the crossbeams.

[0013] In some examples, the crossbeam includes an inner tube and two outer tubes, the two ends of the inner tube being inserted into the two outer tubes and slidingly engaged with the outer tubes, and the outer tubes being connected to the housing.

[0014] In some examples, the outer tube has a slot near the side wall of the housing, the slot extending to the bottom surface of the outer tube, the bottom surface of the outer tube being along the lifting direction of the lifting leg, and the surface of the outer tube near the lifting leg;

[0015] A support rod is connected to the side wall of the box near the outer tube. The support rod is located in the slot to support the outer tube.

[0016] In some examples, the slot includes a guide area and a restriction area, the guide area being located on the side of the restriction area near the bottom surface of the outer tube, and the width of the guide area being greater than the width of the restriction area.

[0017] In some examples, the outer tube has a through-hole on the side wall away from the housing, and the through-hole faces the restricted area.

[0018] In some examples, the bottom surface of the outer tube has a locking hole, and the crossbeam also includes a locking bolt located in the locking hole for abutting against the surface of the inner tube; the desktop assembly also includes a tray located on the side of the crossbeam near the lifting leg, the edge of the tray having a flange located between the bolt head of the locking bolt and the bottom surface of the outer tube.

[0019] Secondly, this application also provides an electric height-adjustable desk, which includes a desktop, a drive mechanism, and an electric height-adjustable desk support as described in the first aspect. The desktop is connected to at least a portion of the two crossbeams and the two longitudinal beam supports. The drive mechanism is at least partially located in the housing and is used to drive the lifting legs to rise and fall.

[0020] The beneficial effects of the technical solutions provided in this application include at least the following:

[0021] The table is height-adjustable by a desktop assembly and two support assemblies. The desktop assembly supports the tabletop. Each support assembly includes lifting legs and a housing. The housing houses the drive mechanism that adjusts the height of the lifting legs. The desktop assembly includes two crossbeams and two longitudinal beam supports. The two longitudinal beam supports are located at both ends of the crossbeams and connected to them, forming a support structure that stably supports the tabletop. Each longitudinal beam support includes a top plate, side plates, and a first hook. The top plate connects to the crossbeams, providing better support for the tabletop. The first hook connects to the edge of the side plate away from the top plate and can be used to hang objects. The top plate, side plates, and first hook are integrated components. Compared to welding the side plates and first hooks, the integrated longitudinal beam support provides a smoother connection between the first hook and the side plate. The rust-preventive layer, applied by painting or other methods, adheres more firmly to the connection, is less prone to peeling, and helps delay corrosion. Attached Figure Description

[0039] Figure 1 This is a structural schematic diagram of an electric height-adjustable desk bracket provided in an embodiment of this application. Figure 1 As shown, the electric height-adjustable desk support includes a desktop assembly 10 and two support assemblies 20.

[0040] Figure 2 This is an exploded structural diagram of an electric height-adjustable desk support provided in an embodiment of this application, as shown below. Figure 2 As shown, the desktop assembly 10 includes two crossbeams 11 and two longitudinal beam supports 12, with the two crossbeams 11 arranged in parallel and spaced apart. The two longitudinal beam supports 12 are respectively arranged at both ends of the crossbeams 11, and each longitudinal beam support 12 is connected to the two crossbeams 11 respectively.

[0041] Figure 3 This is a partial structural diagram of an electric height-adjustable desk bracket provided in an embodiment of this application, as shown below. Figure 3 As shown, the longitudinal beam support arm 12 includes a top plate 121, a side plate 122 and a first hook 123. The top plate 121 is connected to the cross beam 11, one side of the side plate 122 is connected to one side of the top plate 121, and the first hook 123 is connected to the other side of the side plate 122 away from the top plate 121. The top plate 121, the side plate 122 and the first hook 123 are an integrated structural component.

[0042] Two support components 20 are located at both ends of the crossbeam 11. Each support component 20 includes a lifting leg 21 and a housing 22. The housing 22 is located at the top of the lifting leg 21 and is connected to the lifting leg 21. The housing 22 is located between the two crossbeams 11 and is connected to the crossbeam 11.

[0043] By setting up a desktop assembly 10 and two support assemblies 20, the desktop assembly 10 can be used to support the desktop board 100. The support assembly 20 includes lifting legs 21 and a housing 22. The housing 22 can be used to install a drive mechanism that drives the lifting legs 21 to adjust the height of the electric height-adjustable table. The desktop assembly 10 includes two crossbeams 11 and two longitudinal beam supports 12. The two longitudinal beam supports 12 are respectively arranged at both ends of the crossbeams 11 and connected to them, thus forming a support structure to stably support the desktop board 100. The longitudinal beam supports 12 include a top plate 121, a side plate 122, and a first hook 123. The top plate 121 is connected to the crossbeams 11 and can better support the desktop board 100. The first hook 123 is connected to the edge of the side plate 122 away from the top plate 121 and can be used to hang objects. The top plate 121, side plate 122 and first hook 123 are integrated structural components. Compared with the side plate 122 and first hook 123 connected by welding, the connection between the integrated longitudinal beam support arm 12, the first hook 123 and the side plate 122 is smoother. The anti-rust layer formed by painting or other methods is also more firmly attached to the connection and is not easy to peel off, which helps to delay corrosion.

[0044] The top plate 121, the side plate 122, and the first hook 123 are integrated structural components, meaning that the top plate 121, the side plate 122, and the first hook 123 can be formed through an integrated processing technology, for example, by bending the same sheet material. This not only ensures a tight connection between the first hook 123 and the side plate 122, making it less prone to breakage, but also reduces processing costs.

[0045] Figure 4 This is a structural schematic diagram of a longitudinal beam support arm provided in an embodiment of this application, as shown below. Figure 4 As shown, the first hook 123 includes a first straight portion 1231, a second straight portion 1232, and a third straight portion 1233. One end of the first straight portion 1231 is connected to the side plate 122. The first straight portion 1231, the second straight portion 1232, and the third straight portion 1233 are connected in sequence. The lines of intersection of the first straight portion 1231 and the second straight portion 1232, the lines of intersection of the second straight portion 1232 and the third straight portion 1233, and the lines of intersection of the side plate 122 and the top plate 121 are parallel to each other.

[0046] Since the three intersecting lines are parallel, the top plate 121, the side plate 122, and the first hook 123 can be bent in the same direction during processing, simplifying the process. The intersecting lines can be the bending lines used when bending the sheet metal.

[0047] The first straight section 1231, the second straight section 1232, and the third straight section 1233 can all be straight plate-like structures.

[0048] In some examples, the side plate 122 is perpendicular to the top plate 121, the first straight portion 1231 is perpendicular to the second straight portion 1232, and the third straight portion 1233 is perpendicular to the second straight portion 1232. In the longitudinal beam support arm 12, the bent portions are bent at right angles, which not only makes processing easier but also prevents objects from easily falling off the first hook 123 when suspended.

[0049] Figure 5 This is a schematic diagram of the structure of a desktop component provided in an embodiment of this application, such as... Figure 5 As shown, the crossbeam 11 includes an inner tube 111 and two outer tubes 112. The two ends of the inner tube 111 are inserted into the two outer tubes 112, and the inner tube 111 and the outer tubes 112 are in sliding fit.

[0050] By configuring the crossbeam 11 to include an inner tube 111 and two outer tubes 112, and inserting both ends of the inner tube 111 into the two outer tubes 112, the inner tube 111 and the outer tubes 112 can slide relative to each other, thereby adjusting the length of the two ends of the inner tube 111 inserted into the outer tubes 112 to change the length of the crossbeam 11.

[0051] The top plate 121 and the side plate 122 can be perpendicular to each other. The top plate 121 can be connected to the top surface of the outer tube 112, and the side plate 122 is opposite to the end of the crossbeam 11. The top plate 121 can be used to connect to the tabletop 100.

[0052] like Figure 5 As shown, the outer wall of the inner tube 111 has scale lines 1111 distributed along the length direction from one end to the other.

[0053] Because the outer wall of the inner tube 111 has graduation lines 1111 distributed along its length from one end to the other, the length of both ends of the inner tube 111 inserted into the outer tube 112 can be precisely controlled when the length of the crossbeam 11 is changed. This ensures that the two inner tubes 111 are inserted into the outer tube 112 at the same length, giving the desktop assembly 10 sufficient assembly precision. When the electric height-adjustable table needs to be repositioned, the length of both ends of the inner tube 111 inserted into the outer tube 112 can be precisely adjusted according to the space size and the graduation lines 1111, thereby adjusting the length of the crossbeam 11 and allowing the electric height-adjustable table to adapt to different spaces.

[0054] The length of the inner tube 111 inserted into the outer tube 112 can be adjusted by a small-scale fine adjustment, such as 0mm to 10mm, or by a larger-scale adjustment, such as 10cm to 20cm.

[0055] like Figure 5 As shown, the scale line 1111 can be located on the top surface of the inner tube 111. The top surface of the inner tube 111 is the surface of the inner tube 111 away from the lifting leg 21 along the lifting direction of the lifting leg 21, while the bottom surface of the inner tube 111 is the surface of the inner tube 111 close to the lifting leg 21 along the lifting direction of the lifting leg 21.

[0056] Similarly, the top surface of the outer tube 112 is along the lifting direction of the lifting leg 21, and the outer tube 112 is away from the surface of the lifting leg 21. The bottom surface of the outer tube 112 is along the lifting direction of the lifting leg 21, and the outer tube 112 is close to the surface of the lifting leg 21.

[0057] When the electric height-adjustable desk is in normal position, the lifting direction of the lifting leg 21 can be vertical. The lifting leg 21 can include a base rod 211 and a lifting rod 212. One end of the lifting rod 212 can be sleeved on the base rod 211, and the other end of the lifting rod 212 is connected to the housing 22. The lifting rod 212 can move relative to the base rod 211 along its own length.

[0058] By arranging the scale line 1111 on the top surface of the inner tube 111, when adjusting the length of the two ends of the inner tube 111 inserted into the outer tube 112, it is convenient to observe the scale line 1111 and the end face of the inner tube 111 from above the desktop component 10.

[0059] In some examples, the inner tube 111 has a rectangular cross-section, and the width of the top surface of the inner tube 111 is smaller than the width of the side surface adjacent to the top surface. The width directions of both the top and side surfaces of the inner tube 111 are perpendicular to the length direction of the inner tube 111. The width of the side surface of the inner tube 111 can be the distance between the top and bottom surfaces of the inner tube 111.

[0060] The inner tube 111, with a rectangular cross-section, has strong resistance to bending, especially due to the wider side surface, which enhances its resistance to bending in the vertical direction. The rectangular cross-section of the inner tube 111 also provides a flat top surface, facilitating the arrangement of the scale lines 1111.

[0061] Figure 6 This is a partial structural diagram of a desktop component provided in an embodiment of this application, such as... Figure 6 As shown, the bottom surface of the outer tube 112 may have a locking hole 112a. The crossbeam 11 also includes a locking bolt 1121, which is located in the locking hole 112a. The locking bolt 1121 is used to abut against the surface of the inner tube 111.

[0062] Before adjusting the length of the inner tube 111 inserted into the outer tube 112, the locking bolt 1121 can be loosened first. After adjustment, the locking bolt 1121 can be tightened to press against the surface of the inner tube 111, preventing the inner tube 111 from loosening.

[0063] For example, the locking bolt 1121 can be threaded to the outer tube 112.

[0064] In some examples, the same outer tube 112 may have two or more locking holes 112a, each of which may be provided with a locking bolt 1121 to more stably lock the inner tube 111.

[0065] like Figure 6 As shown, the outer tube 112 has a slot 112b on the side wall near the box 22, and the slot 112b extends to the bottom surface of the outer tube 112.

[0066] Reference Figure 3 As shown, a support rod 221 is connected to the side wall of the box 22 near the outer tube 112. The support rod 221 is located in the slot 112b to support the outer tube 112.

[0067] When assembling the desktop assembly 10 and the support assembly 20, the two crossbeams 11 and the two longitudinal beam supports 12 can be fitted over the two housings 22, aligning the slots 112b with the support rods 221. Gradually lower the desktop assembly 10, allowing the support rods 221 to slide from the bottom of the outer tube 112 into the slots 112b.

[0068] like Figure 6 As shown, the card slot 112b includes a guide area 112c and a restriction area 112d. The guide area 112c is located on the side of the restriction area 112d near the bottom surface of the outer tube 112, and the width of the guide area 112c is greater than the width of the restriction area 112d.

[0069] The width direction of the guide area 112c and the width direction of the restriction area 112d are both parallel to the length direction of the outer tube 112.

[0070] When assembling the desktop assembly 10 and the support assembly 20, the wider guide area 112c facilitates the alignment of the support rod 221, guiding the support rod 221 to slide into the narrower restrictive area 112d. The narrower width of the restrictive area 112d and the smaller gap between it and the support rod 221 reduce the wobbling of the desktop assembly 10, making the electric height-adjustable desk bracket more stable.

[0071] like Figure 6 As shown, the outer tube 112 has a through hole 112e on its side wall away from the box 22, and the through hole 112e is directly opposite the restricted area 112d.

[0072] The through hole 112e facing the restricted area 112d allows for easy observation of the relative position of the support rod 221 and the restricted area 112d during the assembly of the desktop component 10 and the support component 20.

[0073] Furthermore, after the desktop assembly 10 and the support assembly 20 are assembled in place, they can be easily fastened. For example, the support rod 221 can be a bolt, and the support rod 221 is detachably connected to the housing 22. After the desktop assembly 10 and the support assembly 20 are assembled in place, the bolt can be tightened so that the bolt head presses the outer tube 112 against the side wall of the housing 22 near the surface of the housing 22.

[0074] like Figure 6 As shown, the desktop assembly 10 may also include a tray 13 located on the side of the crossbeam 11 near the lifting leg 21. The edge of the tray 13 has a flange 131 located between the bolt head of the locking bolt 1121 and the bottom surface of the outer tube 112.

[0075] The tray 13 is positioned below the crossbeam 11 and can be used to hold items. For example, the cables of electrical appliances placed on the electric height-adjustable table can be placed in the tray 13.

[0076] The tray 13 is installed by using the engagement of the bolt head of the locking bolt 1121 with the flange 131, so that the tray 13 does not affect the length adjustment of the crossbeam 11, and the installation is simple and convenient.

[0077] The tray 13 can be elastic. During assembly, the tray 13 can be installed after the locking bolt 1121 is installed. By pressing the tray 13, the tray 13 is deformed so that the flange 131 abuts against the locking bolt 1121.

[0078] like Figure 6 As shown, the desktop assembly 10 also includes a connecting beam 14 and a second hook 15. The connecting beam 14 is connected to the top surface of the outer tube 112, which is connected to the same housing 22, in one of the two crossbeams 11. The second hook 15 is located between the two crossbeams 11, and is located on the side of the connecting beam 14 closer to the outer tube 112. The second hook 15 is connected to the outer tube 112.

[0079] Connecting the outer tube 112 via the connecting beam 14 improves the stability of the desktop assembly 10. Additionally, the second hook 15 can be used for cable management. Positioning the second hook 15 directly below the connecting beam 14 creates a space between the hook 15 and the beam 14 to secure the cables and prevent them from becoming loose.

[0080] For example, the second hook 15 can be welded to the outer tube 112.

[0081] In some examples, the second hook 15 can also be connected to the connecting beam 14, so that the second hook 15 is also assembled when the connecting beam 14 is assembled.

[0082] Figure 7 This is a structural schematic diagram of an electric height-adjustable desk provided in an embodiment of this application, as shown below. Figure 7 As shown, the electric height-adjustable desk includes a desktop panel 100, a drive mechanism, and as shown in the figure. Figures 1-6 Any of the electric height-adjustable desk supports 200 shown. The desktop 100 is at least partially connected to two crossbeams 11 and two longitudinal beam supports 12, and the drive mechanism is at least partially located in the housing 22, the drive mechanism being used to drive the height-adjustable legs 21 to rise and fall.

[0083] For example, the drive mechanism may include a motor to electrically drive the lifting leg 21.

[0084] The specific structure of the drive mechanism can be the same as that in related technologies, as long as it can drive the lifting leg 21 to rise and fall.

[0085] The electric height-adjustable desk may include multiple desktop panels 100, each with a different length. This allows the desktop panels 100 to be replaced after adjusting the dimensions of the electric height-adjustable desk support 200, so that the dimensions of the desktop panels 100 match the dimensions of the electric height-adjustable desk support 200.

[0086] In some examples, the desktop panel 100 can be made of wood, and the electrically adjustable desk bracket 200 can be connected to the desktop panel 100 using screws. For example, screws can be screwed into the desktop panel 100 from below the top plate 121. The screws can be self-tapping screws. After adjusting the dimensions of the electrically adjustable desk bracket 200, the screws can be re-screwed to secure the desktop panel 100.

[0087] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
