The space occupation is large, and the light weight and high reliability requirements cannot be met. SUMMARY

[0003] The electric energy distribution assembly of the new energy flying car provided by the embodiment of the application can realize the connection of multiple layers of circuits in a limited space through the arrangement of the busbar stack, thereby improving the space utilization.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an electric energy distribution assembly of a new energy flying car, comprising

[0005] The box body comprises an upper cavity.

[0006] A plurality of electric energy distribution systems are arranged on both sides of the upper cavity. The electric energy distribution system comprises a plurality of electrical element modules, at least including a solid-state relay module arranged at one end of the upper cavity and a wire harness module arranged on one side of the box body.

[0007] The stack busbar is arranged along the length direction of the solid-state relay module. The stack busbar comprises a plurality of conductive busbars of the stack busbar and a plurality of insulating layers of the stack busbar. The plurality of insulating layers of the stack busbar are arranged in a vertical direction in a stack.

The wire harness module is electrically connected to the conductive busbars of the stack output busbar and the conductive busbars of the stack busbar, and is electrically connected to the electrical element modules.

[0009] Compared with the prior art, the utility model has the advantages that:

[0010] The design of the stacked main busbar and the stacked output busbar makes the power transmission path more compact, reduces the space occupation, and through the stacked arrangement, the connection of multiple layers of circuits can be realized in limited space, thereby improving the space utilization. At the same time, each electrical element module (such as solid-state relay module, wire harness module, etc.) in the power distribution assembly is connected through the conductive busbar, forming a modular structure, which is not only convenient for installation and maintenance, but also makes the entire assembly more compact and orderly.

[0011] Traditional wire connection often has the problems of messy lines and complex wiring, while after using busbar connection, the power transmission path is more clear and simple, reducing the interference and conflict between lines, improving the reliability of the assembly, and reducing the weight of the whole machine.

[0012] The busbar is usually made of lightweight and high-strength metal materials (such as aluminum and its alloys), which has higher conductivity and lower weight compared to traditional wires, which makes the entire power distribution assembly achieve significant lightweight while ensuring performance.

[0013] The setting of multiple sets of power distribution systems means that when one set of power distribution system fails, the failed system can be quickly cut off, and other power distribution systems still support power distribution, providing continuous power supply for the flying car. This redundant design greatly improves the reliability of the system.

[0017] As an improvement, the electrical element module further comprises an explosion-proof fuse and a relay, which are electrically connected through the busbar, and together constitute a double protection mechanism for the system; the explosion-proof fuse can quickly melt and cut off the circuit when the current abnormally increases to a dangerous level, preventing safety accidents such as equipment damage and fire. The relay can monitor the slight changes of current, voltage and other parameters in real time, and quickly act when potential faults are detected, providing timely protection.
