[0024] Example 1

[0025] This embodiment is an all-in-one controller for hybrid electric vehicles, and its structural diagram is shown in FIG. Figure 1-Figure 4As shown, the controller includes a main shell 1 and an upper cover 2, on which a strong electric terminal 3 and a signal line connector 4 are installed. The inner bottom wall of the main shell 1 is installed with a vehicle controller 5, an extended-range controller 6 and a rectifier 7 through thermal silicone grease, and can also be installed through thermal aluminum strips. The strong electric terminal 3 and the signal line connector 4 are electrically connected to the vehicle controller 5, the extended-range controller 6 and the rectifier 7 through a wiring harness. The vehicle controller 5 is adapted to a 72V battery pack and a 2kW mid-mounted motor, and has functions such as controlling a Hall sensor, an electric door lock, a turning handle, reversing, braking, anti-theft, button slow descent, a one-line communication, and voice broadcasting. The extended-range controller 6 is adapted to a 72V battery pack and a 5kW generator set, and has a damper motor. Control function, throttle motor control function, automatic manual start and stop function of the generator set, the rectifier 7 is suitable for a maximum current of 150A, and has the function of converting the AC power of the generator set into DC power for the battery to increase the endurance, the signal line connector 4 is used to integrate the weak current signals of the vehicle controller 5 and the range extender controller 6 and output them to the outside, and a plurality of heat dissipation fins 8 are integrally formed on the main shell 1, and the heat dissipation fins 8 are used to conduct heat to the outside of the main shell 1; after the signal line connector 4 and the upper cover 2 are screwed and fixed, they are located in the main shell 1, and an opening is opened on the upper cover 2 to facilitate the connection of the cable and the signal line connector 4. This embodiment integrates the vehicle controller 5, the range extender controller 6 and the rectifier 7, so it is also a three-in-one controller.

[0026] like Figure 1 and Figure 2 As shown: In this embodiment, a plurality of through holes 9 are provided on the upper cover 2, and screws for fixing the main shell and the upper cover are arranged in the through holes. Threaded holes for matching the screws are provided on the main and object bodies. The front and rear sides of the bottom end of the main shell 1 are fixedly connected with a first mounting plate 10, and a plurality of long strip mounting holes 11 are provided on the first mounting plate 10 to facilitate adjustment of the mounting position. The all-in-one controller can be installed in a suitable position through the mounting holes 11 on the first mounting plate 10. At the same time, the main shell 1 and the upper cover 2 can be disassembled, and the internal vehicle controller 5, range extender controller 6 and rectifier 7 are very convenient to install.

[0027] In order to better connect the Figure 1 and Figure 3 As shown: In this embodiment, the high-voltage terminal 3 includes a 72V input terminal 301 of the vehicle controller, a UVW output terminal 302 and an extended-range controller input UVW terminal 303, and the signal line connector 4 includes a second mounting plate 13, a plurality of first plug interfaces 1301 arranged on the upper surface of the second mounting plate 13 and a plurality of second plug interfaces 1302 arranged on the lower surface of the second mounting plate 13, and the second mounting plate 13 is fixedly connected to the upper cover 2.

[0028] like Figure 1 and Figure 2As shown: In this embodiment, the heat dissipation fins 8 are fixedly connected to the right side of the main shell 1, and a waterproof vent valve 12 is installed on the upper cover 2.

[0029] The vehicle controller 5, the range extender controller 6 and the rectifier 7 are installed on the inner bottom wall of the main shell 1 through thermal grease, which can quickly transfer heat to the main shell 1 as a whole when in use, and a plurality of heat dissipation fins 8 are integrally formed on the main shell 1, which can increase the contact area with the air.

[0030] like Figure 4 As shown: In this embodiment, two positioning holes 14 are provided on the upper surface of the main shell 1, and a positioning column 15 corresponding to the positioning hole 14 is fixedly connected to the lower surface of the upper cover 2. The positioning column includes a cylinder and a cone connected to the cylinder, and a cross groove that divides the positioning column into four equal parts. The cross groove divides the entire positioning column into four deformation bodies. Through this structure, the purpose of positioning can be achieved, and the convenience, firmness and stability of the upper cover and the main shell after installation can be ensured during installation.

[0031] In addition, further, the main shell 1 and the upper cover 2 can be better combined together through the positioning holes 14 and the positioning posts 15. Since the sizes of the positioning posts 15 on the left and right sides are different, the outer diameters of the two positioning posts are different, and the positioning holes that match the two positioning posts also have diameters that are different. After the left and right ends of the upper cover 2 are placed incorrectly, the positioning holes and the positioning posts will not correspond, thereby forcing the staff to turn the upper cover 2 over, which plays a role in preventing mistakes.

[0032] Example 2

[0033] The difference from implementation 1 is that, Figure 5 and Figure 6 As shown, the heat dissipation fins 8 are fixedly connected to the lower surface of the main shell 1, and the interior of the main shell 1 is provided with a first chamber 101 and a second chamber 102. The vehicle controller 5, the range extender controller 6 and the rectifier 7 are all installed inside the first chamber 101. The inner bottom wall of the second chamber 102 is installed with an inverter 16 through thermal grease. The inverter 16 is used to invert DC power into 220V AC power. The high-voltage terminal 3 also includes an inverter 220V output terminal 304. In addition to integrating the vehicle controller 5, the range extender controller 6 and the rectifier 7, this embodiment also integrates the inverter 16, so it is also called a four-in-one controller.

[0034] In this way, the vehicle's 72V DC power can be inverted into 220V AC power to cope with sudden power outages, thereby realizing a four-in-one design of the vehicle controller 5, the range extender controller 6, the rectifier 7, and the inverter 16. This not only makes the internal structure compact, saves the controller's installation space, and makes the controller's functions more centralized, but also is conducive to the development trend of systematization and integration.

[0035] like Figure 5 and Figure 6 As shown: In this embodiment, a cooling fan 17 connected to the second chamber 102 is installed on the front of the main housing 1, and an air outlet is installed on the back of the main housing 1. The cooling fan 17 is provided to send external air into the interior of the main housing 1, so that the heat of multiple components and the internal hot air are discharged from the air outlet, thereby improving the heat dissipation effect. A dustproof net can be provided in the air outlet to intercept large particles of dust entering, thereby better reducing the entry of dust into the interior of the main housing 1 and preventing dust accumulation;

[0036] An air switch 18 is installed inside the second chamber 102 . The air switch 18 is used to protect the inverter 16 when the inverter 16 is overloaded.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
