Description

Foldable portable electric height-adjustable table Technical Field

[0001] This application relates to the field of electric height-adjustable desk technology, specifically a foldable and portable electric height-adjustable desk. Background Technology

[0002] An electric height-adjustable desk is a modern piece of office furniture that uses an electric drive system to raise and lower the desktop to meet user needs in different scenarios. It typically consists of legs, a desktop, an electric drive system, and a controller. The legs are generally telescopic, commonly featuring two- or three-section lifting columns to provide different height ranges.

[0003] For example, patent CN210055077U discloses a three-section electric height-adjustable table. It includes a tabletop and support legs. The support legs are connected to the bottom of the tabletop, and a main beam is set at the bottom of the tabletop, with a support leg connected to each end of the main beam. Each support leg consists of three sections of tubes of different thicknesses, designated as tube number one, tube number two, and tube number three, which are nested together to form a cavity through which the three tubes pass. An electric push rod is installed within the cavity. This invention has the characteristics of simple structure, unstable lifting process, limited space adjustment, and unstable lifting drive.

[0004] In everyday use, when the aforementioned electric height-adjustable desk is folded, a gap of a certain width appears between the tabletop and the legs. Children are typically active and curious about their surroundings, and their self-protection awareness is relatively weak. While playing, they often don't notice these potentially dangerous gaps and can easily reach in and touch them, resulting in their hands getting caught and causing accidental injury. Therefore, the gap between the tabletop and legs of this electric height-adjustable desk, when folded, poses a significant risk of children getting their hands caught. Therefore, it is necessary to provide a foldable and convenient electric height-adjustable desk to solve this problem.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] 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.

[0028] As shown in Figures 1-5, this application provides a foldable portable electric height-adjustable table, including a height-adjustable table assembly 1. The height-adjustable table assembly 1 includes a first tabletop 11, a first mounting frame 13 fixedly installed at the bottom of the first tabletop 11, and a hinge 15 fixedly installed at one end of the first mounting frame 13. A second mounting frame 14 is fixedly installed at the movable end of the hinge 15, and a second tabletop 12 is fixedly installed on the second mounting frame 14. The second tabletop 12 can be rotated along the hinge point with the first tabletop 11 to be suitable for folding the first tabletop 11 and the second tabletop 12 (as shown in Figure 2).

[0029] It should be noted that the combination of the second mounting frame 14 and the first mounting frame 13 is defined as a frame group;

[0030] A lifting assembly 2 is provided at the lower end of the lifting table assembly 1. The lifting assembly 2 includes four sets of movable table legs 21 located at the lower end of the lifting table assembly 1. A movable part 25 is fixedly installed at one end of each movable table leg 21. The movable part 25 is connected to the frame assembly via a damping hinge. The damping hinge is a common existing technology. Its internal structure and working principle will not be explained in detail here. Its function is to provide a certain resistance and stability for the connection between the movable table leg 21 and the frame assembly, so as to ensure that the rotation of the movable table leg 21 is smooth and controllable during the lifting process of the table.

[0031] A supporting table leg 22 is movably sleeved at one end of the movable table leg 21. A mounting cavity (not shown in the figure) adapted to the movable table leg 21 is provided on the supporting table leg 22. A push rod motor 23 is fixedly installed on the bottom surface of the inner wall of the mounting cavity, and the output end of the push rod motor 23 is fixedly installed with the movable table leg 21.

[0032] It should be noted that a controller can be fixedly installed at the bottom of the first tabletop 11. This controller is connected to the push rod motor 23 via a circuit. The user can send corresponding command signals to the push rod motor 23 by operating the buttons and other control elements on the controller. After receiving the command, the push rod motor 23 controls its own operation according to the signal requirements, thereby pushing the movable table leg 21 to move up and down within the mounting cavity of the supporting table leg 22, ultimately realizing the automatic lifting function of the entire height-adjustable table.

[0033] Meanwhile, a connecting rod 24 is fixedly installed between the two sets of horizontally arranged support table legs 22. The connecting rod 24 is used to reinforce and support the support table legs 22, so as to enhance the stability and strength of the entire support structure, so that the lifting table can better bear the weight during use and reduce problems such as shaking or deformation caused by unstable support.

[0034] Furthermore, storage slots 16 are provided on both sides of the first tabletop 11. The storage slots 16 are open and a protective component 3 is provided inside the storage slots 16. The protective component 3 includes two sets of fixed seats 31 fixedly installed at both ends of the inner wall of the storage slot 16, and a fixed rod 32 is fixedly installed between the two sets of fixed seats 31 vertically arranged. A sliding block 33 is slidably installed on the fixed rod 32, and a connecting rod 34 is fixedly installed on the side of the two sets of sliding blocks 33 that are close to each other. A protective plate 35 is hinged to one end of the connecting rod 34.

[0035] It should be noted that the protective plate 35 and the connecting rod 34 can be installed using a damping hinge, so that the protective plate 35 can remain at any angle during rotation.

[0036] Furthermore, a shielding part 36 is fixedly installed at one end of the protective plate 35. The shielding part 36 is adapted to contact and adhere to the side of the first table board 11 when the protective plate 35 is completely inside the storage slot 16.

[0037] When protective component 3 is needed, the user can pull the connecting rod 34 out of the storage slot 16 along the fixed rod 32, since the sliding block 33 can slide on the fixed rod 32. At this time, the protective plate 35 is hinged to the connecting rod 34 and can rotate around the hinge point. By using a damping hinge, the damping force generated by the damping hinge during the rotation of the protective plate 35 can keep it at any angle, allowing the user to adjust the protective plate 35 to a suitable blocking state according to the position and angle of the gap between the tabletop and the table legs. When protective component 3 is not needed, push the connecting rod 34 to make the sliding block 33 slide along the fixed rod 32, pushing the protective plate 35 back into the storage slot 16.

[0038] When the protective panel 35 is unfolded, it can effectively cover the gap between the tabletop and the table legs when the first tabletop 11 and the second tabletop 12 are folded. Especially in environments with children, it can reduce the risk of children accidentally sticking their fingers into the gap and getting pinched, ensuring the safety of users. At the same time, the protective component 3 is normally stored in the storage slot 16 without taking up extra space.

[0039] To prevent the protective plate 35 from sliding on the fixed rod 32 via the sliding block 33 when it is folded in the storage slot 16, as shown in Figures 3-4, a waist groove 17 is provided on the side of the first table board 11 and connected to the storage slot 16. A side rod 37 is fixedly installed on the side of the sliding block 33. The side rod 37 passes through the waist groove 17, and a rotating part 38 is movably sleeved at one end of the side rod 37. It should be noted that one end of the side rod 37 passes through the rotating part 38, and an anti-detachment part (not shown in the figure) is provided at one end of the rotating part 38 to prevent the rotating part 38 from falling off the side rod 37.

[0040] A buckle 39 is fixedly installed at one end of the rotating part 38, and a buckle hole 18 adapted to the buckle 39 is opened on the side of the first table 11. The buckle 39 is made of flexible material.

[0041] When the protective plate 35 is folded into the storage slot 16, the sliding block 33 is located on the fixed rod 32 near the bottom of the storage slot 16, and the connecting rod 34 and the protective plate 35 connected to it are also in the storage slot 16. At this time, the side rod 37 fixed to the side of the sliding block 33 passes through the waist slot 17, and one end of the side rod 37 passes through the rotating part 38, and the rotating part 38 is prevented from falling off by the anti-detachment part.

[0042] To fix the position of the protective plate 35, the user holds and rotates the rotating part 38. Since the side rod 37 is fixedly connected to the sliding block 33, and the rotating part 38 can rotate around one end of the side rod 37, the rotation of the rotating part 38 causes the buckle 39 to rotate as well. The buckle 39 is made of a flexible material, and during rotation, it gradually presses against the side of the first tabletop 11. As the rotation angle increases, the buckle 39 eventually aligns with the buckle hole 18 on the side of the first tabletop 11 and engages within the buckle hole 18. At this point, the side rod 37 is against one end of the waist groove 17, and the position of the entire protective plate 35 is fixed, preventing it from sliding on the fixed rod 32 via the sliding block 33.

[0043] When the protective plate 35 needs to be used again, rotate the rotating part 38 in the opposite direction to disengage the fastener 39 from the fastener hole 18. At this time, the protective plate 35 is no longer restricted in position and can be pulled out of the storage slot 16 for use by sliding the sliding block 33 on the fixing rod 32.

[0044] In summary: By protecting and shielding both sides of the folded first tabletop 11 and second tabletop 12, when in use, the side of the folded first tabletop 11 and second tabletop 12 symmetrical to the hinge 15 should contact the bottom surface, and then;

[0045] When the first tabletop 11 and the second tabletop 12 are in the folded state, the user holds the second tabletop 12 and rotates it around the hinge point with the first tabletop 11, using the hinge 15 as the axis, so that the first tabletop 11 and the second tabletop 12 are on the same plane, forming a complete tabletop. At this time, the frame assembly (composed of the first mounting frame 13 and the second mounting frame 14) provides stable support for the tabletop.

[0046] When unfolding is required, the user holds the second tabletop 12 and rotates it clockwise around the hinge point with the first tabletop 11, using the hinge 15 as the axis. During rotation, the frame assembly (first mounting frame 13 and second mounting frame 14) works together to provide stable support for the tabletop. As the rotation angle gradually increases, the second tabletop 12 and the first tabletop 11 gradually come to lie on the same plane, completing the unfolding of the desktop and presenting a fully usable desktop form.

[0047] After the desktop is unfolded, the user presses the corresponding button according to their needs. The controller transmits the command signal to the push rod motor 23 through the circuit. After receiving the signal, the push rod motor 23 pushes the movable table leg 21 that is tightly fixed to it. Under the push of the push rod motor 23, the movable table leg 21 begins to move up and down within the supporting table leg 22. At the same time, the connecting rod 24 between the two sets of horizontally arranged supporting table legs 22 enhances the stability and strength of the entire support structure, so that the height-adjustable table can better bear the weight during the height adjustment process, reducing swaying or deformation, until the desktop is adjusted to the user's desired height.

[0048] When in situations requiring protection, such as with children, the user activates the protective component 3. The user reaches into the storage slots 16 on either side of the first tabletop 11 and grasps the connecting rod 34. Since the sliding block 33 can slide freely on the fixed rod 32, the user can easily pull the connecting rod 34 out of the storage slot 16 along the fixed rod 32, and the protective plate 35 is pulled out accordingly. Because the protective plate 35 is connected to the connecting rod 34 via a damping hinge, the user gently rotates the protective plate 35 according to the actual position and angle of the gap between the tabletop and the table legs. The damping force generated by the damping hinge allows the protective plate 35 to remain at any desired angle, thus accurately and effectively covering the gap between the tabletop and table legs when the first tabletop 11 and the second tabletop 12 are folded.

[0049] When the protective panel 35 needs to be stored after use, the user pushes the connecting rod 34, causing the sliding block 33 to slide along the fixed rod 32, pushing the protective panel 35 back into the storage slot 16. Next, the user holds the rotating part 38 and rotates it. Since the side rod 37 is fixedly connected to the sliding block 33, and the rotating part 38 can rotate around one end of the side rod 37, the rotation of the rotating part 38 causes the buckle 39 to rotate as well. The buckle 39 is made of flexible material and gradually presses against the side of the first tabletop 11 during rotation. As the rotation angle increases, the buckle 39 eventually aligns with the buckle hole 18 on the side of the first tabletop 11 and engages within the buckle hole 18. At this point, the side rod 37 is against one end of the waist groove 17, and the position of the entire protective panel 35 is firmly fixed, preventing it from sliding on the fixed rod 32 via the sliding block 33.

[0050] When the table needs to be stored, the user first ensures that the protective panel 35 has been folded and secured in the storage slot 16 as described above. Then, holding the second tabletop 12 again, rotate it counterclockwise around the hinge 15 to fold it together with the first tabletop 11. Throughout the folding process, the damping hinges between the movable table legs 21 and the frame assembly ensure smooth rotation. After folding, place the unprotected side against the ground to save space and facilitate storage.

[0051] The protective component 3 effectively covers the gaps created when the tabletop and legs are folded, reducing the risk of children accidentally putting their fingers into the gaps and getting injured. This significantly ensures user safety, making it especially suitable for families or places with children. When not in use, the protective component 3 is stored in the storage slot 16, taking up no extra space and further improving space utilization efficiency.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
