Description

Technical Field

[0001] The present invention relates to the technical field of lifting tables, and in particular to an intelligent lifting table system which can be electrically lifted, lifted and flipped. Background Art

[0002] The automatic lifting table can drive the desktop to rise and fall through a motor, thereby adjusting the height of the desktop. This allows users to alternate between sitting and standing, avoiding sitting for long periods of time and affecting human health.

[0003] For example, the Chinese patent document with the publication number CN215649735U previously applied by our company discloses an ultra-small quick-install lifting device, comprising: a table top portion and a table leg portion; the table top portion comprises a plurality of panels split in a first direction of the table top; the table leg portion comprises a lifting leg installed on one of the panels and supporting the table top portion in a raised state; the lifting leg is assembled through a pivot shaft and generates rotational folding along a second direction of the table top; the lifting leg does not exceed the coverage range of the panel on which it is located at least in a folded state; the first direction and the second direction are intersecting.

[0004] In the above technical solution, the folding combination of different parts can achieve a minimized storage state for easy packaging and transportation. However, the inventors found in the long-term use that the desktop of the lifting table is generally installed horizontally to adapt to most usage scenarios. When the user's arm rests on the desktop, due to the angle between the upper arm and the forearm, the arm will be suspended for a long time, thus affecting the comfort of long-term use. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent lifting table system that can be electrically raised and lowered and electrically flipped, so that users can fully support their arms when using the table in different postures, thereby improving the comfort of long-term use.

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] like Figures 1 to 5As shown, the present invention discloses an intelligent lifting table system that can be electrically lifted and flipped, including a desktop 2, the desktop 2 is connected to a column 1, the desktop 2 includes a fixed part 21 and a rotatable rotating part 22, a rotating support seat 3 is provided under the desktop 2, the rotating support seat 3 is used to connect the fixed part 21 and the rotating part 22, and provide a rotation center for the rotation of the rotating part 22, the rotating support seat 3 is connected to a driving device, when the user uses the lifting table, the driving device can drive the rotating part 22 to rotate around the rotation center provided by the rotating support seat 3, the setting angle of the rotating part 22 can be adjusted to adapt to the angle between the upper arm and the forearm, so that the desktop 2 can fully contact the user's arm to fully support the arm, thereby improving the comfort of long-term use.

[0025] In this embodiment, the specific structure of the rotating support seat 3 includes a support frame 31 and a rotating frame 32. The support frame 31 is fixed to the fixed portion 21, and one end of the rotating frame 32 is fixed to the rotating portion 22, and the other end is rotatably connected to the support frame 31. In this way, the intersection of the rotating frame 32 and the support frame 31 can form a rotation center for the rotating portion 22 to rotate, and the rotation center is opposite to the intersection of the fixed portion 21 and the rotating portion 22. In this way, it is possible to avoid an excessive gap between the rotating portion 22 and the fixed portion 21 when the rotating portion 22 rotates, thereby ensuring that when the angle between the rotating portion 22 and the fixed portion 21 is adjusted, the desktop 2 as a whole always has a good aesthetic appearance;

[0026] In addition, a rotatable lead screw 4 is provided on the support frame 31, and the setting direction of the lead screw 4 is consistent with the extension direction of the support frame 31. With this design, the drive device and the rotating support seat and other components 3 can be installed on the desktop 2 without being installed on the column 1. In this way, the load borne by the column 1 can be reduced to improve the overall stability of the lifting table. The outer periphery of the lead screw 4 is provided with a slider 5 that can form a threaded fit with the lead screw 4. A connecting rod 6 is provided between the support frame 31 and the rotating frame 32. One end of the connecting rod 6 is rotatably connected to the slider 5, and the other end is rotatably connected to the rotating frame 32. The slider 5 is connected to the rotating frame 32 through Move along the direction of the lead screw 4, and the connecting rod 6 drives the rotating frame 32 to rotate around the rotation center. In this way, the lead screw 4 is driven to rotate by the driving device, so that the slider 5 which is sleeved on the outer periphery of the lead screw 4 and forms a threaded match with the lead screw 4 can slide along the direction of the lead screw 4. Since one end of the connecting rod 6 is rotatably connected to the slider 5 and the other end is rotatably connected to the rotating frame 32, as the slider 5 slides, the rotating frame 32 can be driven by the connecting rod 6 to rotate around the rotation center provided by the rotating support seat 3, thereby realizing the adjustment of the angle between the rotating part 22 and the fixed part 21;

[0027] Among them, the connecting rod 6 abuts against the rotating frame 32, and the rotating frame 32 abuts against the supporting frame 31. In this way, when the screw 4 rotates, the connecting rod 6 abutting against the inner wall of the rotating frame 32 and the supporting frame 31 can limit the slider 5 in the radial direction when the slider 5 slides, thereby preventing the slider 5 from rotating with the rotation of the screw 4, so as to ensure the stability of the slider 5 moving along the direction of the screw 4 as the screw 4 rotates.

[0028] In addition, the advantage of using the lead screw 4 as a matching component for the sliding of the slider 5 in this embodiment is that, since the lead screw 4 has higher precision, the slider 5 can have a shorter unit sliding distance, so that the angle between the rotating part 22 and the fixed part 21 can be adjusted more accurately, so as to facilitate adjustment to the most comfortable angle for the user.

[0029] In this embodiment, the specific structure of the driving device includes a driving motor 71 and a right-angle gear box 72, wherein the right-angle gear box 72 is a component for changing the movement direction of the shaft, and mainly comprises a bevel gear pair that meshes with each other inside;

[0030] The right-angle gear box 72 is fixed to the support frame 31, one end of the lead screw 4 is connected to the output end of the right-angle gear box 72, and the output end of the drive motor 71 is connected to the input end of the right-angle gear box 72. In this way, through the setting of the right-angle gear box 72, the drive motor 71 can be installed on one side of the support frame 31, so that the overall structure of the drive device is more compact, and after the output end of the drive motor 71 rotates, the lead screw 4 can be driven to rotate through the transmission action of the right-angle gear box 72, so that by controlling the drive motor 71, the sliding distance of the slider 5 on the lead screw 4 can be adjusted, so that the adjustment of the angle between the rotating part 22 and the fixed part 21 is more convenient.

[0031] In this embodiment, the rotating support seat 3 is further symmetrically arranged below the desktop 2. The symmetrically arranged rotating support seat 3 can improve the stability of the connection between the fixed portion 21 and the rotating portion 22. Since the symmetrically arranged rotating support seat 3 is located on both sides of the desktop 2, the fixed portion 21 can be subjected to more uniform force and run more smoothly when rotating, thereby facilitating the entire fixed portion 21 of the desktop 2 to rotate smoothly.

[0032] Secondly, since the rotating support seat 3 is symmetrically arranged, a synchronization rod 8 is arranged, and the two ends of the synchronization rod 8 are respectively connected to the right-angle gear boxes 72 on both sides to realize power transmission. In this way, the rotating frames 32 on both sides can be driven by a single drive motor 71 to rotate around the rotation center provided by the rotating support seat 3 at the same time, thereby further making the overall driving device more compact.

[0033] In this embodiment, a first clearance arc 211 and a second clearance arc 221 are respectively provided at the coupling point of the fixed portion 21 and the rotating portion 22. Therefore, by setting the first clearance arc 211 and the second clearance arc 221, a certain space can be reserved between the fixed portion 21 and the rotating portion 22 to prevent interference with the rotation of the rotating portion 22, thereby ensuring the stability of the rotating portion 22 during rotation.

[0034] In this embodiment, a mounting frame 9 is further provided below the desktop 2, and the mounting frame 9 is fixed to the fixed portion 21. The mounting frame 9 is used to install the column 1. A support rod 10 is provided on the mounting frame 9, and the support rod 10 includes a fixed bracket 101 and a movable bracket 102. The fixed bracket 101 is fixed to the mounting frame 9. Firstly, the setting of the mounting frame 9 can improve the overall strength of the fixed portion 21, and can provide an installation position for the support rod 10, that is, the movable bracket 102 is fixed to the rotating portion 22, and the fixed bracket 101 and the movable bracket 102 are rotatably connected through a rotating shaft. A torsion spring 11 is provided on the rotating periphery, and resistance is provided to the rotation between the fixed bracket 101 and the movable bracket 102 through the torsion spring 11, and the movable bracket 102 is connected to the rotating portion 22, so that the torsion spring 11 can balance the dead weight of the rotating portion 22, so that it is convenient for the connecting rod 6 to drive the rotating frame 32 to rotate around the rotation center provided by the rotating support seat 3.

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
