A control module of a window shade includes a drive axle affixed with a sleeve, an arrester assembled around the sleeve, a cord drum connected with an operating cord, a clutch operable to couple and decouple the cord drum with respect to the drive axle, and a release unit including a stick that is operatively connected with the arrester. The arrester blocks rotation of the drive axle in a locking state, and has an unlocking state allowing rotation of the drive axle. The operating cord is pulled to drive the cord drum in rotation and turn the clutch to a coupling state, such that the rotation of the cord drum is transmitted through the clutch to drive the drive axle in rotation for raising the shading structure. Moreover, the stick is operable to switch the arrester from to the unlocking state for lowering the shading structure by gravity action.

A gear reducer has a helical gear, an eccentric shaft that is joined to the helical gear and has a first supporting portion that is offset in a rotation radial direction with respect to a rotation shaft of the helical gear, and a slider plate that is disposed at a radial direction outer side of the eccentric shaft. Further, the gear reducer has a transmitting gear that is supported at a first supporting portion, and whose rotation around its own axis is restricted due to the transmitting gear being engaged with the slider plate, and that revolves due to the helical gear rotating together with the eccentric shaft, and has an output gear body that rotates due to the transmitting gear revolving. The transmitting gear has a pair of restricting projections that project-out toward the slider plate side, and the slider plate is disposed between the pair of restricting projections.

A gear train side latching mechanism may include a bracket having one or more guiding features, a handle mechanically coupled to the bracket via the one or more guiding features such that the handle is linearly movable with respect to the bracket, a rack mechanically coupled to the handle comprising a first plurality of gear teeth and configured to move linearly relative to the bracket in a fixed relation to the handle, a driving gear rotatably coupled to the bracket and comprising a compound circular spur gear having a second plurality of gear teeth on an outer diameter of the driving gear and a third plurality of gear teeth on an inner diameter of the driving gear, wherein the second plurality of gear teeth are mechanically coupled to the first plurality of gear teeth, and an actuator gear rotatably coupled to the bracket and comprising a fourth plurality of gear teeth mechanically coupled to the third plurality of gear teeth and further comprising one or more features configured to engage with a corresponding engagement feature of a mechanical member. The gear train side latching mechanism may be arranged such that linear motion of the handle relative to the bracket transmits mechanical energy to the actuator gear via the rack and the driving gear to cause the actuator gear to mechanically interact with the engagement feature to transmit mechanical energy to the engagement feature.

A feeder includes a housing, an ejection structure, and a driving module. The housing includes a discharge channel. The discharge channel has an accommodating space and a discharge port communicated with each other. The ejection structure includes an ejection blade. The ejection blade is rotatably disposed in the accommodating space. The driving module is configured to rotate the ejection structure, so that the ejection blade ejects the feed located in the accommodating space away from the discharge port. The driving module includes a position-returning member configured to maintain the ejection structure in a first rotational orientation relative to the housing. The driving module is further configured to rotate the ejection structure relative to the housing to exceed a second rotational orientation and then release the ejection structure.

A flexible driver, a robot joint, a robot and an exoskeleton robot, the transmission mechanism including an active rotating member, a driven rotating member and a rope, which form a rope drive relationship; wherein, the rope is tightly wound around rotating surfaces of the active rotating member and the driven rotating member, and a rotational central axis of the active rotating member is perpendicular to a rotational central axis of the driven rotating member. An output end of the driving mechanism is connected to the active rotating member, to drive rotation of the active rotating member. The output mechanism includes a flexible driving part, and an output part which is used for connecting to an external actuator. The driven rotating member drives rotation of the output part through the flexible driving part. The flexible driver drives flexibly the actuator through a compact structure as well as reliable and high-efficient transmission.

A differential actuator including: a shuttle supported for rotation around a central axis and including a body portion, a first pinion gear connected to the body portion, and a second pinion gear connected to the body portion; a first component including a first plurality of teeth meshed with the first pinion gear and supported for rotation around the central axis; and a second component including a second plurality of teeth meshed with the second pinion gear and supported for rotation around the central axis. For a first operating mode of the differential actuator: the shuttle is arranged to be rotated by an actuator in a first circumferential direction around the central axis; and the first pinion gear is arranged to rotate the first component in the first circumferential direction around the central axis.

A first operation mechanism 3 includes a first driving source 30 which generates a driving force based on a drive command and a first driving mechanism 32 which inclines a left-side traveling pedal 1c by the driving force from the first driving source 30. The first driving mechanism 32 has a first abutting portion 32a which abuts a pedal surface of the left-side traveling pedal 1c and a first driving unit 32b which inclines the left-side traveling pedal 1c by inclining the first abutting portion. The first driving unit 32b is arranged in a position shifted to a lateral side from a space in which the first abutting portion 32a moves.

A mechanical device for grasping an object without a power source includes a receiver and at least one grabber assembly secured to the receiver. The grabber assembly includes first and second arms with proximal end portions and distal end portions, hooks disposed at the distal end portions, and a mechanical linkage disposed near the proximal end portion of the first arm and the second arm. The mechanical linkage kinematically couples the first arm to the second arm. Displacement of the first arm or the second arm against the object causes movement of the mechanical linkage and thus movement of the second arm or first arm, respectively.

A locking device for a top of a convertible vehicle is proposed, comprising a locking support (22), a locking hook (28), which can be shifted in a translational and rotational manner so as to be displaced between a release position and a locked position, and a driving mechanism for the locking hook (28), said driving mechanism comprising a driving motor (64) and driving a slide (36) movable on the locking support (22). The slide (36) is connected to a driving section of the locking hook (28) via a pull-link arrangement (46) in such a manner that the locking hook (28) undergoes a pivoting movement when the slide (36) is moved. The locking support (22) has an insert having a guiding track for a guiding element which is arranged on the pull-link arrangement (46) or on the locking hook (28), and the guiding track defines a pivot position of the locking hook (28) with respect to the locking support (22).
