Abstract

A control circuit applied to a lifting platform controls a motor to adjust the height of a platform. The control circuit includes an AC/DC conversion circuit, a DC/DC conversion circuit, a detection unit, and a control unit. The detection unit detects an output end of the AC/DC conversion circuit and provides a detection signal. The control unit provides a PWM signal according to the detection signal to control the DC/DC conversion circuit so that the DC/DC conversion circuit converts a DC voltage to an output voltage. When the control unit realizes that the DC voltage or a DC power provided by the AC/DC conversion circuit is less than a power supply threshold according to the detection signal, the control unit decreases a duty cycle of the PWM signal to maintain the DC voltage or the DC power to be greater than or equal to the power supply threshold.

Abstract

An actuator having a manual rotating mechanism and an anti-pinch mechanism includes an actuating body, a manual rotating mechanism, and an anti-pinch mechanism. The actuating body has a stretchable tube. The manual rotating mechanism has a sleeve assembly and a manual rotating wheel. The sleeve assembly has a central shaft and a connecting plate. The anti-pinch mechanism has a clutch wheel which is fixed to the stretchable tube and is movably sleeved around the central shaft. When the stretchable tube is blocked during a retraction stroke, the clutch wheel is detached from the connecting plate such that the clutch wheel follows the stretchable tube to idle. Therefore, the stretchable tube can be manually rotated to retract and the anti-pinch effect during the stretchable tube being retracted can be achieved.

Abstract

An elevating post includes a transmission (10), a driver (20), an outer tube (30) and a moving assembly (40). The driver (20) is connected to the transmission (10). The outer tube (30) receives the transmission (10) and the driver (20) and has a tube body (31) with a longitudinal trough (311). Two closed sections (312, 313) are separately disposed outside two ends of the longitudinal trough (311). The moving assembly (40) is operatably connected to the transmission (10) and has a plate (43) protruding from the tube body (31) by passing through the longitudinal trough (311) and being movable in the longitudinal trough (311).

Abstract

A power-driven table stand with combining mechanotronics includes: a horizontal bar structure (10); a pair of supporters (20), connected at two sides of the horizontal bar structure (10); a pair of vertical post structures (30), connected to each of the supporters (20) and having a motor (31); and an electrical device (40), having a controller (41) and a guide wiring (45), wherein the controller (40) is disposed on the horizontal bar structure (10), the guide wiring (45) is stored and hidden in the horizontal bar structure (10) and each of the supporters (20), and electrically connected to the controller (41) and the motor (31). Accordingly, power wires and signal wires can be effectively and properly stored and hidden.

Abstract

An electric table stand for simple assembly and adjustment includes a beam structure (10), support bars (20), and upright structures (30). Each of the support bars (20) includes a base (21) and a plurality of arms (211, 212, 213) extended from the base (21), wherein an accommodating space (A) is defined by the base (21) and the arms (211, 212, 213). One arm (213) of each of the support bars (20) supports one end of the beam structure (10), and the beam structure (10) is operatively moved in or out of the accommodating space (A). The upright structures (30) are connected to the support bars (20). Accordingly, it is easy to adjust and position each support bar (20) and each upright structure (30) on the beam structure (10).

Abstract

A linear actuator includes a sliding rod, a motor and a buffer assembly. The motor connects the sliding rod to drive the sliding rod. The buffer assembly is disposed at an end of the sliding rod and includes an elastic element and an outer sleeve. The elastic element is received in the outer sleeve. The sliding rod connects the outer sleeve. The outer sleeve is movable along an axial direction of the sliding rod. The elastic element separately pushes an inner wall of the outer sleeve and the sliding rod. The elastic element is pre-compressed along the axial direction of the sliding rod. The buffer assembly can absorb vibration and impact caused by the motor driving the sliding rod.

Abstract

A linear actuator (1) with a buffering mechanism includes an actuator main body (10), a quick release mechanism (30) and a buffering member (50). The actuator main body (10) includes a housing base (11), an outer tube (14) connected to the housing base (11) and an extendable tube (15) penetrating into the outer tube (14). The quick release mechanism (30) is installed on the actuator main body (10). The buffering member (50) is arranged at one side of the outer tube (14). One end of the buffering member (50) is connected to the outer tube (14) or the housing base (11), and another end of the buffering member (50) is connected to the extendable tube (15). Accordingly, the impact force generated during the rapid retraction of the extendable tube can be reduced.
