[0013] Furthermore, the distribution box also provides redundant power supply to the secondary power distribution unit.

[0014] Furthermore, the distribution box is also directly connected to the three-level power distribution unit to supply power to the actuation equipment of the special armored vehicle.

[0024] (1) The starter motor is electrically connected to the engine and is used to start the engine; the ECU controller is electrically connected to the engine and is used to control the engine rotation; the generator and the engine form a generator set; the input terminal of the power controller is electrically connected to the generator and the output terminal is electrically connected to the main distribution box, and is used to control and regulate the electrical energy generated by the generator and input it to the main distribution box; the main distribution box is electrically connected to the battery and is used to receive the battery's electrical energy or charge the battery, and the main distribution box is also electrically connected to the ECU controller, the starter motor, and the distribution box, and is used to provide electrical energy to the ECU controller, the starter motor, and the distribution box; the distribution box is electrically connected to the input of the secondary distribution unit and is used to provide electrical energy to the secondary distribution unit; the output of the secondary distribution unit is electrically connected to the input of the tertiary distribution unit and is used to provide electrical energy to the tertiary distribution unit; the output of the tertiary distribution unit is electrically connected to the terminal load and is used to supply power to the terminal load.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] This embodiment provides a power distribution system based on a special armored vehicle, referring to... Figures 1-4 The power distribution system includes: a power unit, a power supply unit, a primary power distribution unit, a distribution box, a secondary power distribution unit, a tertiary power distribution unit, and terminal loads, wherein:

[0037] The power unit includes an engine, a starter motor, and an ECU controller. The starter motor is electrically connected to the engine for starting it. The ECU controller is also electrically connected to the engine for controlling its rotation. The power supply unit includes a generator, a battery, and a power controller. The generator and engine form a generator set. The power controller's input is electrically connected to the generator, and its output is electrically connected to the primary power distribution unit, for inputting the electrical energy generated by the generator to the primary power distribution unit. The primary power distribution unit is electrically connected to the battery for receiving or charging its electrical energy. It is also electrically connected to the ECU controller, the starter motor, and the distribution box to supply power to these components. Yes, for example, when the generator needs to start, the starter motor converts the electrical energy from the battery into mechanical energy, driving the flywheel on the generator to rotate, thereby driving the various components of the generator to perform a working cycle until the generator starts. After the generator starts, the starter motor automatically disconnects the circuit between itself and the battery. The distribution box is electrically connected to the input of the secondary distribution unit to provide electrical energy to the secondary distribution unit. The distribution box is also directly electrically connected to the tertiary distribution unit to provide electrical energy to the actuating equipment (such as baffles and heat dissipation louvers). The output of the secondary distribution unit is electrically connected to the input of the tertiary distribution unit to provide electrical energy to the tertiary distribution unit. The output of the tertiary distribution unit is electrically connected to the terminal load to supply power to the terminal load.

[0038] Thus, the power distribution system forms a three-level power distribution network. The first-level power distribution unit can directly supply the output energy of the power unit to the ECU controller and the starter motor, while reducing the impact of surges on the operation of the ECU controller and the starter motor. The second-level power distribution unit can realize the process power-on and controllable power supply of the terminal load, thus realizing a stable power supply for special armored vehicles.

[0039] Furthermore, the power distribution box is also electrically connected to the ECU controller and power controller, providing redundant power to them. This further ensures a stable power supply for the special armored vehicle, particularly guaranteeing a reliable and stable power supply to its power and power units. This ensures the vehicle has reliable driving power, preventing it from becoming immobile due to power loss. Simultaneously, the power distribution box also provides redundant power to the secondary power distribution unit, further ensuring a stable power supply for the special armored vehicle. (Refer to...) Figure 1 The distribution box is also directly connected to the tertiary power distribution unit for powering the actuation equipment of the special armored vehicle. In this embodiment, the actuation equipment includes the wave deflector motor and the heat dissipation louver motor of the special armored vehicle. When performing special operations missions such as wading or amphibious operations, special armored vehicles often use wave deflectors to reduce the impact of water waves on the driver's operation. The louvers are mainly used for temperature regulation and gas exchange in the engine compartment of the special armored vehicle, and to prevent debris from entering the engine during rain, snow, or wading / amphibious operations.

[0040] Specifically, in this embodiment, referring to Figure 1 The primary power distribution unit includes the main power distribution box; the secondary power distribution unit includes the troop compartment electrical integrated control box, the power compartment electrical integrated control box, and the operation panel; and the tertiary power distribution unit includes the electrical integrated control boxes for different subsystems of the special armored vehicle.

[0041] Reference Figure 2 The power distribution box is equipped with a power switch 2, which includes power switches corresponding to the secondary power distribution units. These switches are used to independently open / close the power supply path from the power distribution box to the secondary power distribution units, enabling individual control and short-circuit protection for each terminal load branch of the special armored vehicle. This ensures that a short circuit in one branch does not affect other branches. Power switch 2 also includes a powertrain emergency power switch, used to open / close the power supply path from the power distribution box to the ECU controller and power controller, providing emergency power to them. Additionally, power switch 2 includes an actuation equipment power supply switch.

[0042] Specifically, the distribution box comprises a housing 1, a power switch 2 (each branch has an independent fuse mode; relying on the thermal protection of the power switch 2, it can be operated independently and ensures that each branch does not affect the others in the event of a short circuit), a power switch guardrail 3 (to prevent accidental touch and misoperation), and a bridge circuit (integrating four bridge relays to meet the forward and reverse control requirements of the motors for the heat dissipation louvers and wave deflectors). Figure 3 Inside the casing 1, you can see the internal bridge circuit hardware 6), connector input / output port 4 (which realizes the input and output of power distribution box), and emergency working socket 5 (two-wire system, which provides 24V emergency working power output when the main switch is not turned on, and can be used for lighting, etc.).

[0043] In this embodiment, the power distribution box is equipped with ten power switches 2, the specific functions of which are shown in the table below:

[0044]

[0045]

[0046] Reference Figure 3 and Figure 4The distribution box contains a bridge circuit consisting of four relays, used to control the forward and reverse rotation of the anti-surge motor and the heat dissipation louver motor. Taking the heat dissipation louver as an example, first, the "Anti-surge Action Power" switch on the distribution box is turned on, and a 24V control signal is input to interface "01" via a control device (not shown). Interface "04" is grounded. At this time, "02" and "03" output 24V power to drive the heat dissipation louver to unfold. After the heat dissipation louver is fully unfolded, the contact status is fed back (a sensor is installed on the heat dissipation louver), and the control signal input stops. When a 24V control signal is input to interface "04" and interface "01" is grounded, 24V power is output from interfaces "05" and "006" to drive the heat dissipation louver to retract. After the heat dissipation louver is fully retracted, the contact status is fed back, and the control signal input stops.

[0047] The circuit (not shown) that supplies power to the secondary power distribution unit inside the power distribution box consists of multiple branches formed from the power input interface of the power distribution box. Each branch is equipped with a switch, and the outputs of these branches are electrically connected to the troop compartment electrical integrated control box, the power compartment electrical integrated control box, the cockpit electrical integrated control box, and the input terminal of the operation panel in the secondary power distribution unit.

[0048] This power distribution network not only optimizes the control of traditional vehicle power distribution networks and various loads on the vehicle, but also coordinates the relationship between generator power and terminal load equipment. It provides multiple protections for critical loads related to driving safety (such as ECU controllers and power controllers) and secondary power distribution units, and can also achieve forward and reverse control of motor equipment through bridge circuits. Furthermore, it enhances system robustness by ensuring stable power supply to critical equipment and enabling degraded vehicle status awareness during operation (i.e., allowing the special armored vehicle to continue operating even after a power failure of non-critical equipment that does not affect special measurement and driving).

[0049] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
