Description

Technical Field

[0001] This utility model relates to the technical field of self-propelled electric drive products, and in particular to a three-electric system layout structure for an electric self-propelled machine. Background Technology

[0002] In existing technologies, non-road electric drive products typically rely on the "three-electric system" as the core power and control architecture. The three-electric system generally includes three main parts: power battery, motor and electronic control. The power battery is responsible for storing and outputting electrical energy, the motor converts electrical energy into mechanical power to drive the vehicle, and the electronic control system monitors and regulates the transmission of electrical energy and the driving state to ensure the safety and stability of the system.

[0003] Existing electric self-propelled vehicles have many shortcomings in the layout of the three-electric system. First, in terms of space utilization, the dispersed placement of components such as the power battery, high-voltage box, electrical control box, and drive motor results in excessively long connecting cables, which not only increases the complexity and weight of the vehicle layout but also leads to higher energy loss and safety risks. Second, in terms of heat dissipation, the traditional layout fails to effectively combine the spatial relationship between the temperature manager and the power supply components, resulting in insufficient heat dissipation of the power battery and related components. Utility Model Content

[0004] The purpose of this utility model is to provide a three-electric system layout structure for an electric self-propelled machine, which solves the problem that heat dissipation efficiency, wiring safety, and protection safety of the three-electric components cannot be improved by optimizing the structural space layout.

[0005] To achieve this objective, the present invention adopts the following technical solution: An electric self-propelled machine's three-electric system layout structure, installed on a vehicle, includes: a temperature manager, a power supply component, an electric drive component, and an electrical control box. The temperature manager is located at the front of the vehicle body and is used to provide cooling / heating to the three-electric system components and the vehicle's cab air conditioning. The power supply component is located in the middle of the vehicle body and is used to balance the machine's center of gravity and distribute power to the electric drive component and the temperature manager. The power supply component is wiredly connected to the electric drive component, which is used to drive more independent components. The electric drive component and the electrical control box are located at the rear of the power supply component, and the electrical control box is used to distribute power and drive the electric drive component.

[0006] Preferably, the power supply component includes: a high-voltage box and a power battery, the power battery being located at the rear end of the temperature manager, the high-voltage box being located close to the power battery, and the high-voltage box being connected to the electrical control box by wires.

[0007] Preferably, the temperature manager is connected to the high-voltage box wiring.

[0008] Preferably, the electrical control box is located at the rear end of the power battery.

[0009] Preferably, the electric drive assembly includes a first motor and a second motor, wherein the first motor and the second motor are respectively disposed at the rear end of the power battery.

[0010] Preferably, the electrical control box is connected to the wires of the first motor and the second motor respectively.

[0011] Preferably, the first motor and the second motor are provided in multiples.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In use, because the power supply component is located behind the temperature manager, the high-voltage wire connecting the power supply component and the temperature manager is shorter, saving space and optimizing the structural layout. This ensures safe wiring and provides safety protection for the three electrical components. The power supply component is then connected to the temperature manager via wires. The temperature manager then draws in external air and cools it, subsequently distributing the cooled gas or liquid to the electrical control box, power supply component, electric drive component, and the vehicle's cab to cool them down. This solves the problem of not being able to improve heat dissipation efficiency, wiring safety, and the safety protection of the three electrical components through optimized structural layout.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] refer to Figure 1 As shown in the figure, this utility model embodiment provides a three-electric system layout structure for an electric self-propelled machine, installed on a vehicle, including: a temperature manager 1, a power supply component 3, and an electric drive component 4. The temperature manager 1 is located at the front end of the vehicle body and is used to provide cooling / heating to the three-electric system components and the vehicle's cab air conditioning. The power supply component 3 is located in the middle of the vehicle body and is used to balance the center of gravity of the entire machine and to distribute power to the electric drive component 4 and the temperature manager 1. The power supply component 3 is connected to the electric drive component 4 by wires, and the electric drive component 4 is used to drive more independent components. The electric drive component 4 and the electric control box 2 are located at the rear end of the power supply component 3. The electric control box 2 is used to distribute power and drive the electric drive component 4. The temperature manager 1 is a system integrating hardware and control software. Its core function is to regulate the temperature of the target object through heating, cooling, heat conduction, or insulation, thereby ensuring its operational safety, efficiency, and lifespan.

[0021] refer to Figure 1 As shown, the power supply component 3 includes a high-voltage box 301 and a power battery 302. The power battery 302 is located at the rear end of the temperature manager 1, and the high-voltage box 301 is located close to the power battery 302. The high-voltage box 301 is connected to the electrical control box 2 by wires.

[0022] During operation, the power battery 302 provides electrical energy to the high-voltage box 301, which then transmits the internal electrical energy to the electrical control box 2 via wires. The electrical control box 2 then distributes the electrical energy to the temperature manager 1 and the electric drive assembly 4 via wires. Since the temperature manager 1 is fixedly connected to the front of the vehicle body, it is not obstructed by the wheels and draws in external air for cooling. The cooled air or liquid is then distributed to the electrical control box 2, the power supply assembly 3, the electric drive assembly 4, and the vehicle's passenger compartment for further cooling. Simultaneously, because the power battery 302 is in close contact with the temperature manager... 1. At the rear, the temperature manager 1 provides protection for the power battery 302 pack, preventing damage to the power battery 302 from collisions and sharp objects. Since the power battery 302 is in close contact with the temperature manager 1, there is no gap between the power battery 302 and the temperature manager 1, thereby saving space and improving the utilization rate of components. On the other hand, the integrated temperature manager 1 at the front provides the air conditioning cooling / heating function for the cab. It can also be removed when not needed, such as when the machine is not equipped with a cab, and when other systems (such as the hydraulic system) need heat dissipation. It can also be integrated for unified management. It should be explained that the high-voltage box 301 is located near the power battery 302. Its main function is to minimize the distance between the high-voltage box 301 and the power battery 302, reduce wire tangling, and minimize the length of the high-voltage wire connecting the high-voltage box 301 and the power battery 302. At the same time, the high-voltage box 301 and the power battery 302 can be covered by a cover, thus eliminating the need for additional complex protection measures and reducing the risk of exposure of the constantly energized high-voltage wires. On the other hand, the high-voltage box 301, which is located near the power battery 302, can be integrated with the power battery 302 into a single housing through overall encapsulation. Although the power battery 302 is located close to the rear of the temperature manager 1, it is still positioned at the front of the vehicle. Because existing tractors often carry heavy rear-mounted implements during operation, the center of gravity of the entire vehicle shifts significantly to the rear, reducing the load on the front wheels. Therefore, by keeping the power battery 302 at the front of the vehicle, its own weight can balance the heavy rear-mounted implements, making the center of gravity of the entire vehicle closer to the geometric center of gravity in both static and dynamic states. After the front-mounted power battery 302 is replaced, the center of gravity of the entire machine can be balanced by the weight of the power battery 302 itself, so no additional load is required, resulting in lower energy consumption and higher driving efficiency when the vehicle is unloaded.

[0023] refer to Figure 1 As shown, the electric drive assembly 4 includes a first motor 401 and a second motor 402, which are respectively disposed at the rear end of the power battery 302.

[0024] When the aforementioned electrical control box 2 distributes electrical energy to the electric drive assembly 4, it drives the electric drive assembly 4 to operate. Since the first motor 401 and the second motor 402 in the electric drive assembly 4 are directly connected to the gearbox, the first motor 401 and the second motor 402 drive the axle (not shown) and the power output shaft (not shown) respectively through the gearbox. When the vehicle is moving, the first motor 401 is directly connected to the gearbox, and the gearbox transmits power from the first motor 401 to drive the axle (rear axle), while the second motor 402 is in standby mode. When the output shaft is needed during operation, the second motor 402 is started, causing the second motor 402 to drive the gearbox, which then transmits power to external equipment, while the first motor 401 continues to drive the axle.

[0025] refer to Figure 1 As shown, the electrical control box 2 is located at the rear end of the power battery 302.

[0026] The electrical control box 2 is located at the rear of the power battery 302 and on top of the gearbox. The gearbox is fixedly connected to the first motor 401 and the second motor 402, which shortens the distance between the electrical control box 2 and the first motor 401 and the second motor 402. Consequently, the length of the high-voltage wires connecting the electrical control box 2 to the first motor 401 and the second motor 402 is shortened, reducing the weight of the high-voltage wires. At the same time, the electrical control box 2 is located on top of the gearbox, which keeps it away from the ground, thus using the vehicle body to protect it and effectively preventing damage from external physical impacts, flying stones, mud and water impacts, etc. On the other hand, without affecting the height of the cab floor, the rear electrical control box 2 can be located between the power battery 302 and the electric drive assembly 4. In situations where space is limited, or in scenarios with multiple motors, or when the motors are distributed, multiple electrical control boxes 2 can be arranged near the motors. It should be explained that the electrical control box 2 is not just a simple power distribution function, but has a hybrid function that can drive multiple motors and distribute their power. Therefore, the electrical control box 2 can also drive multiple motors through its internal control structure to make the motors work. The control structure can use one or more programmable logic controllers (PLC), digital signal processors (DSP), CAN bus control, etc.

[0027] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
