The passenger cabin 311 is located inside the fuselage 312, and is used to form a passenger space and/or a cargo space, so as to provide a protection space and a living environment for passengers, and also has certain cargo capacity. Further, the fuselage 312 may be an independently-carried frame-type body structure, resulting in a stronger structural stability of the fuselage 312. For example, the fuselage 312 is a frame structure, which is formed by bending, stamping and welding steel profiles, has low weight and strong torsional strength, and can be applied to various types of vehicles, so that the type of the vehicle 300 provided by the application is not limited, and for example, when the vehicle 300 is used as a land vehicle 300, the vehicle can be a car, an urban off-road vehicle, a commercial vehicle, and the like.

The power system 32 is coupled to the fuselage 312, and the type of power system 32 is not limited and may be a land power system, a flight power system, a hydrodynamic system, and the like. For example, powertrain 32, such as a land powertrain, may include at least one of the drive train, steering train, and brake train configurations, and may further include at least one of the following: wheels, tracks, mechanical feet, or other structures that may provide land travel power to the vehicle 300 under the drive of the drive mechanism enable the vehicle 300 to meet land travel requirements.

In some embodiments, the vehicle 300 may further include a power battery pack 33 disposed within the fuselage 312, the power battery pack 33 being configured to provide a source of energy for the vehicle 300, such as for providing electrical energy to the power system 32. The high-voltage distribution box 200 is electrically connected to the power battery pack 33, and is used for controlling the power battery pack 33, or/and monitoring the operation state of the power battery pack 33, so as to ensure the safe operation of the power battery pack 33.
