An engine room heat exhausting structure configured to discharge heat from an engine room, is provided, which includes an engine room accommodating an engine with cylinders lined up in a front-and-rear direction of a vehicle, a wheelhouse provided outside the engine room in a vehicle width direction, an exhaust emission control device disposed between the engine and the wheelhouse, a wheelhouse liner configured to protect an inner wall of the wheelhouse, a discharging part provided rearward of the exhaust emission control device and configured to discharge into the wheelhouse a part of air cooled the exhaust emission control device, and a guiding part provided to the wheelhouse liner and configured to guide the air discharged into the wheel house to underneath the vehicle in a rear part of the wheelhouse.

A fan structure is provided with a fan, a fan support, a base, and a motor. The fan is provided with a rotational shaft rotatable about a rotational shaft, and a blade coupled to the rotational shaft to rotate about the rotational axis together with the rotational shaft. The fan support rotatably supports the rotational shaft. The base slidably supports the fan support so as to be slidable in the sliding direction. The motor includes a motor main body supported by a fan support opposite to the rotational shaft of the fan in the axial direction along the rotational axis, and a motor rotational shaft connected to the rotational shaft so as to rotate the rotational shaft.

A power supply system (10) is used for supplying power to a power system of an electric tractor and comprises a bracket (100) that is provided above and below a frame of a transport trailer, first cases (200) that are provided on the bracket and first power battery packs that are suspended inside the first case. Each of the first cases is provided with a first ventilation structure and a second ventilation structure (211) so that while the transport trailer is moving, wind can enter the first case from the first ventilation structure and be discharged from the second ventilation structure, thus achieving further cooling and heat dissipation for the first power battery packs and avoiding service life being impacted due to the first power battery pack overheating.

The present disclosure discloses an all-terrain vehicle. The all-terrain vehicle includes: a signal acquirer; an engine; an engine controller; a first differential; a first wheel; a driving motor; a motor controller; a battery power source electrically connected with the driving motor; a second differential in transmission connection with the driving motor; and second wheels in transmission connection with the second differential and are located at both lateral sides of the second differential. Therefore, by connecting and matching the first differential, the engine, the driving motor and the second differential with the corresponding components, the hybrid all-terrain vehicle allows intelligent four-wheel drive, reduces energy consumption, and has a compact and reasonable structure.
