A power switching device for switching power between translational motion and rotational motion includes an active gear, a transmission mechanism, a translation mechanism, a functional gear, and a reset mechanism. The active gear can rotate in a first direction or a second direction opposite the first direction. The translation mechanism includes a runner and a pushing member. The active gear can switch between a first position and a second position. In the first position, the active gear meshes with the runner and rotates in the first direction or the second direction to drive the runner to rotate. In the second position, the active gear meshes with the transmission gear and rotates in the second direction to drive the functional gear to rotate.

The invention relates to an actuator with an anti-backbend chain, a drive motor, and a worm which can be driven by the drive motor and which comprises a helical groove. The anti-backbend chain has engagement means and is guided along the worm, and the chain is in engagement with the worm by means of the engagement means and the helical groove to drive the anti-backbend chain. Such an actuator should have a more compact design and should optionally exhibit less wear. For this purpose, the core diameter of the worm is larger than twice the distance from the motor axis to the motor exterior along which the anti-backbend chain is guided, and the anti-backbend chain is guided at least partly along the drive motor by means of the engagement means.

An extension/contraction mechanism capable of preventing a swing of an extension/contraction part when it is extended or contracted is provided. An extension/contraction mechanism according to one aspect of the present disclosure is an extension/contraction mechanism including a telescopic extension/contraction part and a base part that supports the extension/contraction part so that it can be extended/contracted, in which the extension/contraction mechanism includes a support part that contacts an inner peripheral surface or an outer peripheral surface of the extension/contraction part in order to prevent a wobble in a root part of the extension/contraction part with respect to the base part, and the support part is provided on a side surface of the base part that is opposed to the inner peripheral surface or the outer peripheral surface of the extension/contraction part that the support part contacts.

One embodiment provides a drive system that includes a drive device with at least one drum for spooling at least one wire rope. A mounting device is connected to the drive device and a single-axis tracker. At least one partial pulley is connected to a torque tube. The at least one partial pulley is configured to accept the at least one wire rope and to transfer leveraged drive forces to the torque tube.

The present invention discloses a distributed active/passive hybrid cable drive system, including a direct current motor, a magnetorheological actuator module, and a drive gear set. The direct current motor provides power for the system, the magnetorheological actuator adjusts output, a cable is driven to move by using a reel fixedly connected to an output shaft, the power is transmitted to a tail end by using the cable along a Bowden cable, and the tail end is connected to a controlled object, to implement control. The distributed active/passive hybrid cable drive system can implement controllable force output with large torque, small inertia, and high bandwidth, and has a small volume, high efficiency, and low costs compared with a pure motor drive system.

A sealing profile receiving device having first and second holding units for receiving and holding first and second sealing profile elements, and a casting unit for casting a connecting portion for connecting the first and second sealing profile elements and/or for casting first and second end terminations of the first and second sealing profile elements. A first and/or second and/or third drive unit for driving at least one holding and/or clamping and/or ejector element is/are provided and includes a chain comprising a plurality of chain links arranged at least between two guide faces of a guide unit for guiding the chain and/or chain links, such that an adjusting force can be exerted in the pulling and pushing directions of the chain by the first and/or second and/or third drive unit.

This application relates to an actuation system for assistive wearable devices such as exoskeletons designed to actuate a joint of a wearer of the device. The actuation system comprises a cable that connects a guide member arranged on one side of the joint and active components arranged on the other side of the joint. Applying a tension to the cable causes the cable to apply a force to the joint in a superior direction, which translates into a torque of the joint. The actuation system provides the advantages of having a low profile, and being substantially flexible, compliant, lightweight, and comfortable, while having good controllability and force delivery capabilities.
