A high voltage unit installed in a vehicle includes a high voltage component and a casing that accommodates the high voltage component. The casing includes a side wall provided with a pressure receiving portion that receives impact in a horizontal direction and a planer portion on which the high voltage component is arranged, the planer portion being adjacent to an inner side of the side wall. The high voltage component is arranged on the planer portion with a gap from the side wall provided with the pressure receiving portion. An area corresponding to the gap of the planer portion includes a portion, between the pressure receiving portion and the high voltage component, provided with a brittle portion, and includes a portion, other than the brittle portion, provided with a high strength portion having higher strength than the brittle portion.

The present disclosure is directed towards systems, vehicles, and assemblies that include an prime mover, a transmission, and a coupler. The coupler couples the prime mover and the transmission. A preferred embodiment includes a system for forming a rigid body that includes a rotational prime mover and a transmission assembly. The transmission assembly transmits at least a portion of the rotational energy from the prime mover to a driven member at a frequency. The system includes a first and a second bridging member. Coupling the first bridging member to the second bridging member forms a symmetric bridge or coupler. The symmetric bridge is symmetric about a first plane of symmetry. Furthermore, coupling a first portion of the bridge to the rotational prime mover and coupling a second portion of the bridge to the transmission assembly forms the rigid body. The rigid body further includes the bridge.

A power transmission apparatus includes a first electric motor, a power split mechanism, a second electric motor, a case, a support wall, and a breather mechanism. The case accommodates the first electric motor, the power split mechanism, and the second electric motor. The support wall is provided between the power split mechanism and the second electric motor. The breather mechanism is located in a rotational angle range that is at least equal to 90 degrees and is smaller than 180 degrees. The breather mechanism has a through hole and a breather chamber. The breather chamber is provided at a case inner side end of the through hole and is opened in a direction that does not oppose a virtual surface that passes through the rotational axis at a rotational angle of 90 degrees of the second electric motor.

A fuel cell vehicle includes a fuel cell stack, a tank, a discharge flow path discharging a fluid discharged from the fuel cell stack, a muffler attached to the discharge flow paths, and a vehicle member defining a first chamber and a second chamber, the first chamber accommodating the fuel cell stack and the second chamber being disposed behind the first chamber and accommodating the tank and the muffler. The second chamber is also provided with a front portion and a rear portion continuous with the front portion, the rear portion being shorter than the front portion in average length in a vehicle width direction. The muffler is disposed between the tank and one of a pair of side wall portions defining side walls of the front portion in the vehicle width direction.

The invention is directed to a graspable human propulsion device which contains a ducted fan assembly on the aft portion of a longitudinal structure which the user grasps onto, which acts to propel the user along the longitudinal direction of the device while the user is mounted on a human transportation apparatus, such as a skateboard. The user can orient the device so that the ducted fan assembly leads ahead or trails behind the user, according to user preference. In one embodiment, the user controls the direction and amount of thrust by use of a spring twist throttle mechanism. In another embodiment, the user controls the direction and amount of thrust by use of a trigger and switch mechanism. The fore latch and the aft latch allow the user to clamp the device onto a skateboard deck for ease in transporting while on foot.

A hydraulic-circulation powered engine includes: a housing, defining a chamber inside; a rotating disk, a periphery thereof configured with a plurality of sequentially arranged driven elements, the rotating disk configured inside the chamber, and a rotating shaft outputting power configured on a shaft center of the rotating disk and extended out of the housing; a plurality of nozzles, configured on the chamber, and sequentially arranged outside the periphery of the rotating disk, allowing the nozzles to face the driven elements; a liquid pressurizing driver, configured with liquid outlet in communication with the nozzles; and a power supply, in electric connection with the liquid pressurizing driver, allowing the liquid pressurizing driver to be driven to output liquid to each nozzle, thereby ejecting liquid toward the driven elements configured on the periphery of the rotating disk so as to drive the driven elements to turn the rotating disk and rotating shaft.
