Abstract: An electric shelf which has at least one column to be installed on a wall, a slidable component arranged on the column to slide along the column vertically, at least one layer of shelf board component connected to the slidable component to move simultaneously with the slidable component, and a linear driving device connected to the slidable component and the column to actuate the slidable component to move relative to the column. Advantages of the present disclosure compared to prior arts include a simpler structure and less space occupied by the shelf board component.

Abstract: The present disclosure discloses an electric lifting media wall, comprising a base, a lifting component including at least one group of lifting columns with lower ends connected to the base and a drive mechanism driving the lifting columns to ascend or descend, a support frame for connection with a display mounting rack that is connected to the lifting columns and ascends or descends along with the lifting columns synchronously, and a wall shroud that shrouds outside the lifting component and the support frame. The electric lifting media wall is adjustable in height, high in bearing capability, multifunctional, convenient in assembly and disassembly, easy for later maintenance, and small in package size.

Abstract: The present disclosure discloses an exercise bicycle with a desk plate, which comprises a frame, a supporting foot, a seat and a desk plate, the frame including a first upright column to support the desk plate and a second upright column to support the seat, wherein a first lifting assembly is provided on the first upright column to connect the desk plate and the first upright column, and enables the adjustment of the upper and lower positions of the desk plate relative to the first upright column. The height of the desk plate can be adjusted by the first lifting assembly to accommodate users with different figures. It's more ergonomic since the height of the upright column supporting the desk plate can be adjusted. When packing, lower the upright column to the minimum can largely reduce the size of the package.

Abstract: The present disclosure discloses a desk-mounted lifting platform comprising a workbench, an upper support and a low support. The workbench is connected to the upper support. A first lifting arm and a second lifting arm are arranged between the upper support and the lower support. The first lifting arm and the second lifting arm are X-shaped and hinged at an intersection thereof. An upper end of the first lifting arm is hinged with the upper support. A lower end of the first lifting arm is slidably fitted on the lower support. A lower end of the second lifting arm is hinged with the lower support. An upper end of the second lifting arm is slidably fitted on the upper support. A gas spring is arranged between the upper support and the lower support. The gas spring is used for providing a lifting force to lift the upper support.

Advantages of the present disclosure compared to prior arts include a simpler structure and less space occupied by the shelf board component.

Abstract: The invention provides a lifting desk control method including a motor drive unit, a current detection unit and an arithmetic unit. The control method comprises the steps of: detecting current a at the current time t1 and current b at time t2; calculating the current change rate L=(b?a)/(t2?t1); and comparing L with a set value, judging that an obstacle is encountered if the set value is exceeded, and issuing a stopping or retreating instruction to a motor by the motor drive unit. The scheme employed by the invention is to calculate the change rate of current, so judgment is made with higher accuracy and whether an obstacle is encountered is judged with high sensitivity.
