Description

Electric adjustable lifting table top structure

Technical Field

The invention relates to the field of electric furniture, in particular to an electric adjustable lifting table top structure.

Background

Traditional desk is fixed structure, the desktop of desk is planar structure, not only can not incline, also can not go up and down, consequently, there are two drawbacks, on the one hand people in the use, can feel tired because of the time overlength of bending over a desk, especially more inconvenient to the use, on the other hand is because the desk in some families or the office space is not specific to give one person and uses, and everyone's height is all different, children's height can be along with the increase of age and constantly increase, so this kind of desk just can't satisfy the high demand under the different states.

The lifting table solves the problems, the lifting table is generally electric or manual, and the manual lifting table achieves the effect of lifting adjustment or table top adjustment of the table through a manual operation mechanical transmission structure. Although the purpose of flexible adjustment is achieved, the operation is troublesome and laborious.

The automatic lifting table generally uses electricity as a power source, the height of the lifting table is adjusted by controlling a mechanical device through a motor, and the height of the lifting table can also be adjusted by controlling an air pressure rod or a hydraulic rod through a compressor. Its advantages are low electric consumption, high shape stability and beautiful appearance, and wide lifting range. However, such automatic lifting tables still cannot meet the increasingly diversified use requirements. For example, for table top adjustment controls: translation or turnover of the table top. These functions are needed to be developed and novel control schemes need to be simultaneously satisfied to meet the expected requirements of the public.

The two groups of turning assemblies also need to meet the effect of synchronous control, so that the two groups of turning assemblies also have synchronous motion states. Specifically, the upset subassembly includes: the second lead screw, the turnover transmission part and the support arm. The second screw rod is arranged on the second component, and the second screw rod and the first screw rod are arranged along the width direction of the table top. The second screw sleeve is sleeved on the second component, the second screw sleeve is hinged to one end of the support arm, and the other end of the support arm is hinged to the connecting part on the table top plate. Therefore, the second screw rod, the second screw sleeve and the support arm form a slide block connecting rod structure, and the inclining direction of the support arm is the same as the inclining direction of the table top plate. In order to ensure that the table top can be stably overturned, the end part of the table top is hinged on the translation end through the rotating part.

The rotation of the second screw rod is driven by the second motor and the gear box, and the running states of the two groups of overturning components are synchronous, so that the control of the two second motors is synchronous.

The second screw rod synchronously displaces with the translation end, the turnover transmission part drives the second screw rod to rotate, and the support arm moves along with the threaded sleeve on the second screw rod;

the bottom surface of the table top plate comprises a rotating part and a connecting part, the rotating part comprises a rotating shaft of a turnover fulcrum of the table top plate of the seat, and the second screw rod is vertical to the rotating shaft in space. Therefore, the table top plate takes the rotating part as a pivot, and the table top plate is continuously lifted along with the upward inclination of the support arm.
