The disclosure provides an assist wheel including a wheel, a handrim, an elastic component, two contact components, a driving assembly, two film sensors. The wheel is configured to be rotatably disposed on a wheelchair frame. The handrim is disposed on the wheel and rotatable with respect to the wheel. Two opposite ends of the elastic component are respectively connected to the wheel and the handrim. The two contact components are respectively disposed on the wheel and the handrim. The driving assembly is configured to be fixed to the wheelchair frame. The two film sensors are disposed on the driving assembly and respectively pressed by the two film sensors. Each of the two film sensors is configured to generate a sensor value. The controller is configured to receive the sensor values from the two film sensors and signal the driving assembly.

Assist wheel

An engaging device for a wheel is provided. The engaging device includes a wheel hub and a transmitting member. The wheel hub is located in the center of a wheel. The wheel hub has a plurality of engaging holes. The transmitting member has a plurality of grooves, wherein an elastic member is provided in each of the grooves. One end of the elastic member is connected to the groove, and the other end of the elastic member is connected to an engaging member. The shapes of the engaging members and the engaging holes correspond to each other, so that the engaging members fit into the engaging holes.

Engaging device for wheel and wheel set having removable power module

A reinforcement structure for a disc motor being received in the flat space formed at a side of a wheel center for driving the wheel to rotate as it can be activated to perform a rotation movement by the interactions of an electromagnetic field formed from its stators and a magnetic field resulting from its rotator, comprises: a rib structure, arranged inside a shell housing the disc-like stator for enhancing the structure integrity thereof without causing the thickness thereof to increase and thus maximizing the usefulness of the motor's limited space; and a fixing element, for fixing the stators to the inner side of the motor's outer shell for preventing the stators to be deformed by the magnetic force from the permanent magnets mounted on the rotors while preventing the stators from being attracted by the permanent magnets of the rotors, and thus enabling the motor to operate smoothly.

Reinforcement structure for disc motor

The present invention provides a metal hydride canister apparatus having structures capable of discharging hydrogen gas uniformly and exchanging heat effectively, comprising: a shell having a joint arranged in a central hole located on top of the shell, and two via holes arranged respectively at a side of the central hole; a filtering rod connecting to the joint; a pipe having a first end, a second end and a middle section between the first end and the second end; and a metal hydride stored inside the shell; wherein, the first end and the second end of the pipe pass the corresponding via hole in respective, and the middle section of the pipe forms a twin spiral structure wrapping around the filtering rod, the middle section having a first loop interconnecting to a second loop. In a preferred embodiment of the present invention, the filtering rod can be a hollow rod extending toward the bottom of the shell, and is welded on the joint that is further welded to the central hole, in addition, the first end and the second end of the pipe are welded onto the corresponding via holes and are exposed to the outside of the shell, and the first loop and the second loop of the middle section can have equal diameters or different diameters.
