Description

Technical Field

[0001] The present application relates to the technical field of truck thermal management units, and in particular to a thermal management unit for a medium-sized hybrid truck. Background Art

[0002] The thermal management unit of a medium-sized hybrid truck is a complex system that integrates multiple circulation loops. These loops achieve temperature management of various key components of the vehicle through precise control of controllers and components.

[0003] For example, a typical thermal management system for a medium-sized hybrid truck consists of an outer shell and a circuit mounted within it. The circuits can be configured to meet thermal management requirements, including: a first circuit for dissipating heat from the range extender controller, electronic controller, and motor assembly; a second circuit for heating and dissipating the battery pack; a third circuit for circulating refrigerant, providing cooling for the vehicle's air conditioning system; and a fourth circuit for providing heating for the vehicle's air conditioning system. The outer shell primarily serves as a support and protective structure, housing the aforementioned circuits within its interior. However, maintenance of the typical outer shell requires removing the side panels by loosening bolts and other fasteners to access and maintain components within the circuits. Removing or securing the outer shell panels by removing or installing fasteners increases maintenance efforts for the medium-sized hybrid truck's thermal management system. Therefore, we propose a thermal management system for a medium-sized hybrid truck that reduces the need to open or close the outer shell, thereby improving maintenance convenience.

[0008] Furthermore, the two groups of auxiliary opening and closing components are both located above the inlet and outlet pipes of the circulation loop portion, and there is a gap between the auxiliary opening and closing components and the inlet and outlet pipes of the circulation loop portion.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0018] The present application discloses a medium-sized hybrid truck thermal management unit. Figures 1 to 4 The thermal management system for a medium-sized hybrid truck consists of an outer shell and a circulation system. The circulation system can be configured with the following circuits based on thermal management needs: a first circulation system for dissipating heat from the range extender controller, electronic controller, and motor assembly; a second circulation system for heating and dissipating heat from the battery pack; a third circulation system for the refrigerant, providing cooling for the vehicle's air conditioning; and a fourth circulation system for providing heating for the vehicle's air conditioning. The inlet and outlet pipes for each circuit in the circulation system can be extended outside the outer shell and connected to corresponding components via piping. The outer shell includes a chassis 10, side covers 20, and two sets of auxiliary opening and closing assemblies 30. The sides of the chassis 10 are formed with openings that communicate with its interior, and the side covers 20 are positioned to cover the openings. The two sets of auxiliary opening and closing assemblies 30 are mounted on opposite sides of the chassis 10, and the sides of both sets of auxiliary opening and closing assemblies 30 closest to the side covers 20 are connected to the side covers 20. The side cover 20 can be supported and adjusted by two sets of auxiliary opening and closing components 30 to adjust the position of the side cover 20 at the opening of the chassis 10 and complete the opening and closing operation of the chassis 10.

[0019] In this embodiment, the auxiliary opening and closing assembly 30 may include a deflection positioning arm 31, a first connecting arm 32, a second connecting arm 33, a push arm 34, and a linear drive source 35. The two ends of the deflection positioning arm 31 are rotatably connected to the chassis 10 and the side cover 20, respectively. The adjacent ends of the first connecting arm 32 and the second connecting arm 33 are rotatably connected by a pin, and the other end of the first connecting arm 32 and the other end of the second connecting arm 33 are rotatably connected to the chassis 10 and the side cover 20, respectively. Therefore, when the connection between the first connecting arm 32 and the second connecting arm 33 generates a deflection movement, the change in the angle between the first connecting arm 32 and the second connecting arm 33 can be used to drive the side cover 20 to move, and the side cover 20 is supported by the deflection positioning arm 31 that can deflect and move to generate deflection, thereby realizing the covering or deflection movement of the side cover 20 at the opening of the chassis 10 to above the opening of the chassis 10. One end of the push arm 34 is rotatably connected to the chassis 10, and the other end of the push arm 34 is rotatably connected to the side cover 20, and the push arm 34 and the second connecting arm 33 are connected at the same position as the side cover 20. The lower end of the linear drive source 35 is rotatably connected to the chassis 10, and the output end of the linear drive source 35 is rotatably connected to the middle part of the push arm 34. When the output end of the linear drive source 35 produces telescopic movement, it can drive the push arm 34 to deflect, and the push arm 34 and the second connecting arm 33 are connected at the same position as the side cover 20, so that the second connecting arm 33 can also move and realize the automatic opening and closing of the side cover 20. The linear drive source 35 can adopt a power source with an output end that can move along a straight line, such as an electric push rod, a hydraulic push rod, or a pneumatic push rod already in the prior art. In addition, the two sets of auxiliary opening and closing components 30 are both located above the inlet and outlet pipes of the circulation loop part, and there is a gap between the auxiliary opening and closing components 30 and the inlet and outlet pipes of the circulation loop part to avoid interference with movement.

[0020] In this embodiment, the side cover 20 includes a cover plate 21 and two side panels 22. The length and height of the cover plate 21 are respectively adapted to the length and height of the opening of the chassis 10 so that it can cover the opening. The two side panels 22 can be formed on opposite sides of the cover plate 21 by bending operations, so that when the side cover 20 covers the opening of the chassis 10, the two side panels 22 extend to the sides of the opening of the chassis 10. A first boss 23 and a second boss 24 are formed on the side of the side panel 22 facing away from the chassis 10, and the first boss 23 is used for rotational connection with the deflection positioning arm 31, and the second boss 24 is used for rotational connection with the push arm 34 and the second connecting arm 33, respectively.

[0021] In this embodiment, the side cover 20 may further include a shielding pad 25 made of an elastic material. The shielding pad 25 has at least two symmetrically formed buckles 26, and the side panel 22 has a socket that mates with the buckles 26. The side panel 22 can be fastened to the buckles 26 by the sockets, thereby securing the shielding pad 25 to the inner side of the cover 21 and positioning the shielding pad 25 between the cover 21 and the chassis 10. When the side cover 20 is used to shield an opening from the chassis 10, the shielding pad 25 can be used to block the gap between the cover 21 and the chassis 10, thereby improving the sealing effect of the side cover 20 on the opening.

[0022] The system of the present invention may further include a control system for controlling the operation of the linear drive source to automatically operate the side cover. It should be understood that the control system is not particularly limited and can be implemented using existing control technologies, which will not be described in detail here.

[0023] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
