Abstract: The present disclosure relates to security mechanisms for electric motors and associated systems. For example, the present technology includes a powertrain assembly having (1) a motor having multiple sets of coils; (2) a drive circuitry electrically coupled to the multiple sets of coils; and (3) a security unit electrically coupled to the drive circuitry and the multiple sets of coils. The security unit is configured to short-circuit at least one set of the multiple sets of coils responsive to a signal from a controller. The signal indicates that the motor is, or has been, turned off.

Abstract: The present disclosure relates to hub apparatuses and associated systems. An embodiment of the hub apparatus includes a rotor assembly, a shaft, and a stator assembly. The rotor assembly includes first/second housing components and multiple magnets mounted on one or both of the first and second housing components. The stator assembly includes (1) a coil assembly positioned corresponding to the magnets; (2) a main circuit board fixedly coupled to the coil assembly; and (3) a battery assembly positioned inside the coil assembly and carried by the main circuit board.

Abstract: The present disclosure relates to a hub apparatus and associated charging systems. In some embodiments, the hub apparatus includes (1) a housing assembly defining an internal space; (2) a shaft positioned to extend through the housing assembly; (3) a stator assembly fixedly coupled to the shaft; (4) a side cover fixedly coupled to the shaft and rotatably coupled to the housing assembly, the side cover having a base portion and a mating portion extending from the base portion; and (5) a pair of first connectors positioned through the mating portion. Each of the first connectors comprising a terminal end and a contact portion. The terminal end is electrically coupled to a battery assembly via a wire bundle fixedly coupled to the side cover. The contact portion is configured to electrically couple to an external power source so as to charge the battery assembly through a wired connection.

Abstract: A cover assembly for covering a pivot of an electronic device is disclosed. The pivot connects a first component and a second component of the electronic device. The cover assembly is disposed at one side of the pivot, and the cover assembly includes a first covering element and a second covering element. A first end of the first covering element is connected to the first component, and a second end of the first covering element includes a first limit part. A first end of the second covering element is connected to the second component, and a second end of the second covering element includes a second limit part. The first covering element is overlapped with the second covering element. When the pivot rotates, the first limit part and the second limit part move correspondingly.

Abstract: A cover assembly applied to an electronic device is disclosed. The electronic device includes a first component and a second component, and an opening is formed between the first component and the second component. The cover assembly includes a cover element, at least one first moving element, at least one second moving element and an elastic element. The cover element is disposed in the opening, attached to the second component, and abutted against the first component. The first moving element is connected to the cover element and includes at least one first moving part. The second moving element is connected to the second component and includes at least one second moving part. The elastic element is connected between the first moving element and the second moving element, and provides an elastic force to make the cover element continuously abutted against the first component and cover the opening.
