The present application relates to the technical field of a wheel, and particularly to a stored energy transmission mechanism and stored energy-driven wheel. In particular, a stored energy transmission mechanism is integrated with a rotating component, which is used to drive the rotating component. The stored energy transmission mechanism includes a center shaft, an elastic component, a transmission cover, a flywheel, and a flywheel seat. The elastic component is sleeved outside the center shaft and positioned in the transmission cover, with one end being fixedly connected with the center shaft and the other end being fixedly connected with the transmission. When the transmission cover is rotated and fitted with the center shaft, it can tighten the elastic component to store energy.

The present invention provides a coupling device for coupling a rotary actuator to a mechanical device having a rotatable shaft. The coupling device comprises a spring return module with a first rotatable coupling configured to engage a first portion of the shaft, and a spring engaged with the first rotatable coupling, wherein the first rotatable coupling is rotatable about a rotation axis, and wherein rotation of the rotatable coupling about the rotation axis in a first direction causes mechanical energy to be stored in the spring. The coupling device further comprises an actuator coupling module comprising a second rotatable coupling. The second rotatable coupling is configured to engage a second portion of the shaft, the second rotatable coupling being further engageable with an output of the rotary actuator. The second rotatable coupling is rotatable about the rotation axis, the second rotatable coupling being rotatable relative to the first rotatable coupling about the rotation axis.

The present invention provides a spring return device comprising a rotatable drive coupling configured for releasably engaging a rotatable drive part on a first side of the device and configured for releasably engaging a rotatable drive part on an opposite second side of the device. A spring is engaged with the drive coupling, and a retainer retains the spring. The drive coupling is rotatable relative to the retainer, wherein rotation of the drive coupling relative to the retainer in a first direction causes mechanical energy to be stored in the spring. The spring return device further comprises a limiter element that is arranged to rotate with the drive coupling, and one or more stopping surfaces comprising a first stopping surface arranged to abut a first limiter surface on the limiter element when the drive coupling is in a first predetermined rotational position, to thereby limit rotation of the drive coupling relative to the retainer in a second direction, the second direction being opposite to the first direction. The spring return device of the invention may facilitate reversing the direction of operation of the spring return device.

Various embodiments of the teachings herein include an actuating drive comprising: a drive element; an actuation element; and a restoring spring. The drive element drives the actuation element indirectly about an actuation axis. The actuation element includes a shaft portion concentric to the actuation axis and extends at least partially circumferentially. The restoring spring includes a wound flat spring providing a restoring torque on the actuation element, acting tangentially on the shaft portion, and a free spring end tangentially fastened to the shaft portion. The free spring end is radially externally disposed with respect to the spring axis and fastened tangentially to the shaft portion. The spring is mounted rotatably so the spring axis is radially spaced apart from the actuation axis and aligned parallel to the actuation axis.

The invention discloses an energy storage device, comprising a mounting seat, a first spring energy storage component, a second spring energy storage component, a one-way limiter, a transmission component, and a generator; the first spring energy storage component comprises a first rotating shaft, a first spring, and a first spring barrel; the second spring energy storage component comprises a second rotating shaft, a second spring, and a second spring barrel. The device uses two spring energy storage components to collect the gravitational potential energy of different dispersion points at the same time, and store it in the corresponding spring, then through the action of the one-way limiter, the energy of the spring with larger energy storage can be released and converted into electrical energy.

This invention generally relates to pull back toy cars. Specifically, this invention discloses mechanisms relating to uses of a gearbox contained inside an wheel assembly in order to create vibration sensitivity to enhance user experiences. More specifically, the unique feature of placing more than one gearbox in the wheel assembly offers the pull back toy car with more variety in terms of play style, including a wheel-like pull back toy car, a two-wheel pull back toy car with various levels of vibration set by a user. Further, this invention includes the user of a handle attached to a gearbox so that the location of the gearbox placed within the wheel assembly can be changed so that the level of vibration of the wheel assembly or the toy vehicle can also be adjusted freely by the user.

According to embodiments of the disclosed technology, systems and methods are provided for a mobile gateway I.T. system that is configured to receive a message from a source for transmission to a destination and multiple varying communication channels on which to transmit the message to the destination. The system may use a logic control library that is tightly coupled to the mobile gateway and the communication channels. The logic control library may be configured to select a first communication channel from the communication channels to route the message for transmission to the destination. The logic control library may be further configured to select a second communication channel from the communication channels to route the message for transmission to the destination in response to a period of time expiring without receiving a confirmation protocol from the destination via the first communication channel.
