Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The present invention provides an embodiment of a power system layout structure of a pure electric vehicle, including a carrier 1, which is the basic frame of the entire power system. A battery pack 2 is fixedly connected to the top of the carrier 1. The battery pack 2 is the core power source of the pure electric vehicle. A plurality of connecting plates 3 are fixedly connected to the front and rear sides of the battery pack 2. A wiring harness is fixed to the connecting plate 3. A fixing ring 4 is fixedly connected to the front side of the connecting plate 3 to fix the wires. A reset spring 5 is fixedly connected to the right side of the fixing ring 4. After the operation is completed, the fixing ring 4 is automatically reset. A fixing plate 6 is fixedly connected to the right side of the reset spring 5. The fixing plate 6 fixes the reset spring 5 to prevent movement.

[0032] The front side of the fixing ring 4 is fixedly connected with a handle 17, through which the fixing ring 4 can be operated portablely. The left side of the fixing ring 4 is fixedly connected with a limit block 8, and the fixing effect is achieved by the limit block 8. The front side of the connecting plate 3 is fixedly connected with a fixing ring 2 9. The other half of the wiring device, the left side of the fixing ring 2 9 is fixedly connected with a handle 2 10, as above, so that the user can operate the fixing ring 2 9 portablely. The left side of the fixing ring 2 9 is fixedly connected with a reset spring 2, as above, so that the fixing ring 2 9 automatically resets after the operation is completed. The left side of the reset spring 2 is fixedly connected with a fixing plate 2 11, as above, to prevent the reset spring 2 from moving. The top of the carrier 1 is fixedly connected with a heat dissipation component for dissipating heat from the bottom of the vehicle.

[0033] Reference Figure 1 、 Figure 2 and Figure 4The heat dissipation component includes a heat absorbing plate 12. The heat absorbing plate 12 is an important part of the heat dissipation component and is responsible for absorbing heat from the motor 13. A heat dissipation fan 14 is fixedly connected to the top of the heat absorbing plate 12. The heat dissipation fan 14 is installed on the top of the heat absorbing plate 12 and is mainly used to quickly discharge the heat absorbed by the heat absorbing plate 12. A plurality of protective shells 15 are fixedly connected to the top of the battery pack 2 to provide physical protection to prevent the external environment from damaging the battery pack 2. A plurality of heat dissipation holes 16 are provided inside the protective shell 15. The design of the heat dissipation holes 16 can effectively promote air circulation and help dissipate heat. A temperature detector 17 is fixedly connected to the front side of the battery pack 2 to monitor the operating temperature of the battery in real time. When a certain temperature is reached, the heat dissipation fan 19 is started to rotate. A heat absorbing plate 18 is fixedly connected to the bottom of the battery pack 2 to further improve the heat dissipation effect. A plurality of heat dissipation fans 19 are fixedly connected to the bottom of the heat absorbing plate 18 to discharge the heat absorbed by the heat absorbing plate 18.

[0034] Reference Figure 1 and Figure 2 , the rear side of the fixing plate 1 6 is fixedly connected to the front side of the connecting plate 3, and the fixing plate 1 6 supports and fixes the wiring device. The rear side of the fixing plate 2 11 is fixedly connected to the front side of the connecting plate 3. As above, a limiting groove is provided inside the fixing ring 2 9 to limit and guide the movement of the limiting block 8 to ensure that it slides within a predetermined range. The outer portion of the limiting block 8 is slidably connected to the inner portion of the limiting groove to play a role in positioning and limiting, and can stay at a specific position. The left side of the carrier 1 is fixedly connected to a motor 13, which is the power source of the device;

[0035] The bottom of the heat absorbing plate 12 is fixedly connected to the top of the motor 13. The heat absorbing plate is designed for heat exchange and heat absorption by the motor 13. A plurality of wheels are fixedly connected to the far side of the carrier 1. The driving end of the motor 13 is fixedly connected to two rotating rods, which are responsible for driving the wheels to rotate, thereby moving the entire device. The far sides of the two rotating rods are fixedly connected to the inside of the wheels, providing the device with mobility. The front side of the battery pack 2 is fixedly connected to the power supply tube 1, and the top of the power supply tube 1 is fixedly connected to the charging port 20 to facilitate charging operations and ensure that the battery pack 2 can continuously supply power. The rear side of the battery pack 2 is fixedly connected to the power supply tube 2, and the left side of the power supply tube 2 is fixedly connected to the right side of the motor 13 to ensure stable operation of the motor 13.

[0036] Working principle: When in use, when it is necessary to fix the internal wires, press the handle 1 7 to move the fixing ring 1 4, remove the limit block 8 and the limit groove inside the fixing ring 2 9, turn the handle 2 10 to drive the fixing ring 2 9 to move, and place the wires inside it. At this time, the fixing ring 1 4 is automatically reset by the reset spring 1 5, and the handle 2 10 is turned to drive the fixing ring 2 9 to move, so that the limit block 8 falls into the limit groove inside the fixing ring 2 9, thereby completing the fixation of the wires and achieving a neat and easy to organize effect.

[0037] When dissipating heat from the bottom of the vehicle, the heat absorbing plate 12 is close to the top of the motor 13 to absorb the heat generated by the motor 13. At this time, the heat absorbing plate 12 is dissipated by the cooling fan 14. The protective shell 15 on the top of the battery pack 2 is provided with heat dissipation holes 16, which can ventilate and dissipate heat for the battery pack 2. The protective shell 15 also plays a protective role for the battery pack 2. When the vehicle speed is too fast, the temperature of the battery pack 2 rises rapidly. When the temperature detector 17 reaches a certain temperature, the heat absorbing plate 18 at the bottom absorbs heat from the battery pack 2. The heat absorbing plate 18 is quickly dissipated by the multiple cooling fans 19 at the bottom, thereby achieving the heat dissipation effect.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
