  • Publication number: 20200069046
    Abstract: An elevation working platform includes a lower support and an upper support. At least one group of X-type elevation mechanisms is provided between the lower support and the upper support. The elevation working platform further includes an elastic element. A first end of the elastic element is connected between two end points of a first support rod or a second support rod. A second end of the elastic element is connected to the lower support or a second hinging seat capable of sliding relative to the lower support. Using the X-type elevation mechanisms, the front and back positions of the upper support do not change in an elevating process of the upper support, the structure is simple and practical, and the cost is relatively low.

  • Patent number: 10579030
    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.
