Description

An electrically adjustable lift table desktop structure

technical field

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

Background technique

The traditional table is a fixed structure, and the table top of the table is a flat structure, which can not only be tilted, but also can not be lifted, so there are two disadvantages. It is more inconvenient to use. On the other hand, because the desks in some homes or offices are not specific for one person, and everyone's height is different, and the height of children will continue to grow with age. , so this kind of table cannot meet the height requirements in different states.

The birth of the lifting table solves the above problems. The lifting table is generally divided into electric and manual. The manual lifting table can achieve the effect of table lifting adjustment or desktop adjustment by manually operating the 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 the power source, and the height of the lifting table is adjusted by the motor control mechanism. The advantages are that the power consumption is small, the style is stable and beautiful, and the range of lifting is large. However, such automatic lifting desks are still unable to meet the increasingly diversified use needs. For example, for the adjustment control of the tabletop: translation or flip of the tabletop. These functions are in urgent need of development, and need to meet the needs of novel control design in parallel, in order to meet the expectations of the public.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an electrically adjustable lifting table top structure, which solves the problem that the table top board can be adjusted to its own and comfortable position when the chair is not moving, especially the problem that the table top angle can be flipped.

The technical scheme of the present invention is: an electrically adjustable lifting table top structure, comprising a support frame as a structural carrier. The support frame serves as the basis for carrying and also serves as the basic frame of the desktop. Specifically, the support frame is a frame formed by splicing profiles and having the length direction of the desktop and the width direction of the desktop. The outer shell is generally installed on the outside of the support frame, which can ensure the appearance of the desktop board is beautiful.

The entire table top structure of the lifting table is installed on the legs of the lifting table, and the table top plate has the functions of in-plane translation and tilting.

In addition to the basic frame, the table top structure of the elevating table also includes electrically controlled adjustment components, namely: a translation component and a flip component. Both the translation component and the flip component are arranged in the support frame. Specifically, the flip component is arranged on the translation component, and the desktop board is arranged on the flip component. Therefore, the principle of motion is that the translation component can move in a plane with the flip component and the desktop board on the flip component, and the flip component provides the power to tilt the desktop board.

The translation assembly is a linear telescopic structure, and there are two sets of translation assemblies; the two sets of translation assemblies are arranged in parallel, so they have a uniform direction of expansion; the two sets of parallel assemblies are driven synchronously, so they have a unified operating state. Specifically, the translation assembly includes: a first part and a second part that play a guiding effect. The first part and the second part are both hollow square tubes, and the second part is nested in the first part. Therefore, the second part can slide and extend along the first part, and the end of the second part protruding relative to the first part is the translation end. The sliding and telescopic direction of the second component is the adjustable translation direction.

The transmission problem is solved by the screw structure between the first part and the second part. Specifically, a first screw rod is arranged in the first part, and a first screw sleeve is installed at the end of the second part, and the first screw The sleeve is assembled on the first screw rod, and when the first screw rod rotates forward or reverse, the second part will slide relative to the first part along with the first screw sleeve.

The first screw rod is driven by the translational transmission part, and a gear box is matched at the end of the first screw rod. The gear box is also matched with a transmission rod perpendicular to the first screw rod. A group of translation components is provided, and the transmission rod is driven by a first motor and a gear box.

The flipping assembly is a sliding block linkage mechanism to drive the lifting structure, and the flipping assembly is also provided with two groups, and each flipping assembly is matched with a translation assembly. The two sets of flipping components also need to satisfy the effect of synchronous control, so the two sets of flipping components also have a synchronous motion state. Specifically, the flipping assembly includes: a second screw rod, a flipping transmission part, and a support arm. The second screw rod is arranged on the second component, and both the second screw rod and the first screw rod are arranged along the width direction of the desktop. A second screw sleeve is sleeved on the second part, 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 connection part on the desktop board. Therefore, the second screw rod, the second screw sleeve and the support arm form a slider link structure, and the tilt direction of the support arm is the same as the tilt direction of the desktop board. In order to satisfy that the desktop board can be turned stably, the end of the desktop board 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 operating states of the two sets of turning components are synchronized, so the control of the two second motors is synchronized.

a second screw rod that displaces synchronously with the translation end, an overturning transmission part that drives the second screw rod to rotate, and a support arm that moves with the screw sleeve on the second screw rod;

The bottom surface of the desktop board includes a rotating part and a connecting part, the rotating part includes a rotating shaft for the pivot point of the seat desktop board, and the second screw rod is perpendicular to the rotating shaft in space. Therefore, the table board takes the rotating part as a fulcrum, and the table board is continuously raised as the support arm is tilted upward.

The advantages of the present invention are:

1. This structure can realize the horizontal movement and angular tilting of the desktop board of the lifting table, and adopts electric control, which can meet the diverse needs of use.

2. The motor and screw drive are used as the main energy supply, which can ensure the stability of the movement of the desktop board. At the same time, the transmission response of the structure is fast, and the purpose of fast adjustment can be achieved.

3. The overall structure has good stability, low noise, and good operation and use. Moreover, the structural arrangement is reasonable and easy to maintain and repair.
