Description

Technical Field

[0001] This application relates to the field of high-voltage system technology for new energy vehicles, and in particular to a high-voltage accessory module for new energy vehicles. Background Technology

[0002] With the continuous development and application of new energy technologies, the controllers of new energy vehicles are becoming more and more functional and larger in size. Therefore, the requirements for the layout of the engine compartment are becoming more and more stringent, requiring more controllers to be placed in a limited space to meet the performance and functional requirements.

[0003] In related technologies, new energy vehicles generally adopt two modes: pure electric and hybrid. In actual production processes, most adopt the technology of converting oil to electric, that is, changing the traditional engine drive mode of drilling rigs by using multiple high-voltage motors and continuously variable speed hydraulic coupling reducers, replacing the parallel engine drive with AC motor parallel drive.

[0004] However, in order to meet the demand for rapid market launch, the above-mentioned oil-to-electric conversion technology disperses or partially concentrates the high-voltage electrical appliances, high-voltage distribution boxes, thermal management and other components required by the vehicle in the chassis, which brings great difficulties to assembly and maintenance. Summary of the Invention

[0015] In one embodiment, a high-voltage distribution box is used to redistribute the power supply voltage to the power battery. It includes a distribution box body and connection ports, with the connection ports located on both sides of the distribution box body. The distribution box body is connected to the main frame.

[0016] In one embodiment, a power converter, disposed on a horizontal frame of the main frame of the thermal management assembly, is used to convert the high voltage distributed by the high voltage distribution box into a low voltage and supply power to the required components.

[0017] In one embodiment, the main frame includes a plurality of vertical frames and a plurality of horizontal frames. The vertical frames are vertically disposed on top of the thermal management assembly, and the horizontal frames are connected to the vertical frames.

[0019] The horizontal frame includes a first horizontal group, a second horizontal group, a third horizontal group, and a fourth horizontal group;

[0020] The first vertical frame and the third vertical frame are connected by a first horizontal group and a second horizontal group, and the second vertical frame and the third vertical frame are connected by a third horizontal group and a fourth horizontal group.

[0021] In one embodiment, the main frame further includes a first mounting plate, which is an L-shaped plate. The two ends of the first mounting plate are respectively connected to the fourth horizontal group and the third vertical frame. A power converter is provided on the first mounting plate.

[0022] In one embodiment, the main frame further includes a second mounting plate, which is a U-shaped plate, and the side plates of the second mounting plate are respectively connected to the horizontal frame of the third vertical frame.

[0042] Figure 1 This invention relates to a high-voltage accessory module for new energy vehicles. The high-voltage accessory module includes a thermal management component 10 and a main frame 20. The main frame 20 is disposed on top of the thermal management component 10. Suspension 80 is provided at both the front and rear ends of the main frame 20. A protective plate 210 is provided on the outer surface of the main frame 20. An assembly space can be obtained by assembling the main frame 20, the protective plate 210 and the thermal management component 10.

[0043] The high-pressure accessory module also includes an electric air compressor 30, an auxiliary power unit 40, a high-voltage distribution box 50, a low-voltage controller 60, and a power converter 70, among other accessories, which are arranged within the assembly space. The connection ports for these accessories are located on both sides of the main frame 20, and several openings are provided on the protective plate 210 corresponding to these connection ports. After assembly, it is connected to the vehicle frame via suspension mounts 80. The suspension mounts 80 include a front suspension mount 810 and a rear suspension mount 820. The front suspension mount 810 is located on both sides of the vertical frame at the front end of the main frame 20, and the rear suspension mount 820 is located at the rear end of the main frame 20. The suspension mounts 80 are rubber mounts.

[0044] By mounting the main frame 20 on the thermal management component 10, and defining a mounting cavity with a gap between the main frame 20 and the thermal management component 10, accessories other than the thermal management component 10 in the high-pressure accessory module are placed in the mounting cavity and the gap. By placing the accessories in a limited space, a high degree of integration can be achieved. The high-pressure accessory module is relatively small overall, which can save more layout space for the chassis. At the same time, the high-pressure accessory module is connected to the vehicle frame through the front suspension 810 and the rear suspension 820, which helps to alleviate the vibration transmitted by the frame and improves the vibration reduction effect of the module.

[0045] Figure 2 This is one of the internal structural schematic diagrams of a high-voltage accessory module for new energy vehicles according to an embodiment of the present invention. The high-voltage accessory module includes a thermal management component 10 and a main frame 20. The main frame 20 is disposed on top of the thermal management component 10, and a protective plate 210 is disposed on the outer surface of the main frame 20. Suspension mounts 80 are connected to both the front and rear ends of the main frame 20. The main frame 20 defines a mounting cavity above the thermal management component 10. The mounting cavity includes a first mounting cavity 220 and a second mounting cavity 230. The first mounting cavity 220 is disposed above the front end of the thermal management component 10, i.e., on the front side of the main frame 20, and the second mounting cavity 230 is disposed above the rear end of the thermal management component 10, i.e., on the rear side of the main frame 20.

[0046] Then, an electric air compressor 30 and an auxiliary power unit 40 are installed in the first mounting cavity 220. The electric air compressor 30 is located in the left half of the first mounting cavity 220, and the auxiliary power unit 40 is located in the right half of the first mounting cavity, that is, the electric air compressor 30 and the auxiliary power unit 40 are arranged side by side. Simultaneously, one air compressor port of the electric air compressor 30 is connected to the air inlet of the auxiliary power unit 40 via a pipe. (Refer to...) Figure 2 The pipe connected to the air compressor port passes through the protective plate 210 on one side of the main frame 20. The pipe goes from one side of the main frame 20, through the front end of the main frame 20, around to the other side of the main frame 20, and then from the other side of the main frame 20, through the front end of the main frame 20, around to one side of the main frame 20, and then through the protective plate 210.

[0047] The electric air compressor 30 is integrated with the auxiliary power unit 40. The electric air compressor 30 needs to be connected to the air filter and the filter element needs to be replaced regularly. The auxiliary power unit 40 also needs to have its filter element replaced regularly. Therefore, the whole unit is arranged on the front side above the component housing 110 of the thermal management component 10.

[0048] A high-voltage distribution box 50 is installed within the second mounting cavity 230. The high-voltage distribution box 50 includes a distribution box body 510 and connection ports 520. The distribution box body 510 is connected to the main frame 20 by bolts. The connection ports 520 are located on both sides of the distribution box body 510, and the protective plate 210 has openings at the connection ports 520. The connection ports 520 include, but are not limited to, low-voltage interfaces, high-voltage interfaces, charging interfaces, pre-charge resistor interfaces, communication interfaces, and water pump power supply interfaces. These connection ports 520 are integrated into a specific area of ​​the distribution box body 510 of the high-voltage distribution box 50.

[0049] A main frame 20 is set on top of the heat pipe assembly 10. The main frame 20 forms a first mounting cavity 220 and a second mounting cavity 230 based on the frame. An electric air compressor 30, an auxiliary power unit 40, and a high-voltage power distribution box 50 are then set in the mounting cavity. The high-voltage accessories are set in a limited space, which can achieve a high degree of integration. At the same time, a protective plate 210 is set on the outer surface of the main frame 20, which not only protects the accessories inside the module, but also facilitates the maintenance of accessories in a single mounting cavity, thereby improving maintenance efficiency. Furthermore, a suspension 80 is set on the main frame 20, which can effectively reduce the vibration transmitted by the frame and improve the vibration reduction effect of the module.

[0050] Figure 3 This is a second schematic diagram of the internal structure of a high-voltage accessory module for new energy vehicles according to an embodiment of the present invention. A low-voltage controller 60 is also provided between the first mounting cavity 220 and the second mounting cavity 230, and the connection interface of the low-voltage controller 60 is located on the side.

Connection ports are provided on the side of the assembly housing 110 at the corresponding valve bodies. Figure 2 The thermal management component 10 shown has an L-shaped top housing 110. The first main frame 20 is located at the top front of the housing 110, and the second main frame 20 is located at the top rear of the housing 110. Figure 2 and Figure 3 It can be seen that the electric air compressor 30 and the auxiliary power unit 40 are both fixed to the first main frame 20 by bolts, and the high-voltage distribution box 50 is fixed to the second main frame 20 by bolts. In addition, it can be seen from... Figure 2 and Figure 3It is known that there is a space of a certain size between the high voltage distribution box 50 and the front top of the thermal management component 10. A power converter 70, such as a DC / DC converter, is installed in this space, and the connection terminals of the power converter 70 are all located on both sides. The protective plate 210 on the main frame 20 has an opening at the corresponding location of the connection terminal.

[0052] The main frame 20 includes several vertical frame bodies 240 and several horizontal frame bodies 250. The vertical frame bodies 240 are vertically mounted on the top of the thermal management assembly 10 by bolts. Adjacent vertical frame bodies 240 are connected by horizontal frame bodies 250, and the horizontal frame bodies 250 and vertical frame bodies 240 are fixed together by bolts. Therefore, the vertical frame bodies 240 and horizontal frame bodies 250 can define and form a first mounting cavity 220 and a second mounting cavity 230.

[0053] Reference Figure 2 and Figure 3 As shown, the vertical frame 240 includes a first vertical frame 241, a second vertical frame 242, and a third vertical frame 243. The first vertical frame 241 and the third vertical frame 243 are vertically arranged on the top front side of the component housing 110, and the second vertical frame 242 is vertically arranged on the top rear side of the component housing 110. That is, the first vertical frame 241 and the second vertical frame 242 are respectively arranged at the top two ends of the thermal management component 10, and the third vertical frame 243 is arranged between the first vertical frame 241 and the second vertical frame 242 and is vertically arranged on the top of the thermal management component 10.

[0054] The horizontal frame 250 includes a first horizontal group 251, a second horizontal group 252, a third horizontal group 253, and a fourth horizontal group 254. The first horizontal group 251 connects the top of the first vertical frame 241 and the third vertical frame 243. The second horizontal group 252 is located at the top of the front end of the component housing 110 and connects the bottom of the first vertical frame 241 and the third vertical frame 243. The third horizontal group 253 connects the top of the second vertical frame 242 and the third vertical frame 243. The fourth horizontal group 254 is located at the top of the rear end of the component housing 110 and connects the second vertical frame 242 and the third vertical frame 243.

[0055] Reference Figure 2 and Figure 3 As shown, the main frame 20 also includes a first mounting plate 260, which is L-shaped. The first mounting plate 260 is disposed between the top of the component housing 110 and the high-voltage distribution box 50, specifically, both ends of the first mounting plate 260 are connected to the fourth horizontal group 254 and the third vertical frame 243, respectively. Therefore, the power converter 70 is connected to the first mounting plate 260 by bolts.

[0056] The main frame 20 also includes a second mounting plate 270, which is a U-shaped plate. The side plates of the second mounting plate 270 are connected to the horizontal frame of the third vertical frame 243.

[0057] A main frame 20 is set on top of the heat pipe assembly 10. The main frame 20 forms a first mounting cavity 220 and a second mounting cavity 230 based on the frame. An electric air compressor 30, an auxiliary power unit 40, a high-voltage power distribution box 50, and a low-voltage controller 60 are then set in the mounting cavity. A power converter 70 is set between the main frame 20 and the heat pipe assembly 10. The high-voltage accessories are set in a limited space, which can achieve a high degree of integration. At the same time, a protective plate 210 is set on the outer surface of the main frame 20, which not only protects the accessories inside the module, but also facilitates the maintenance of accessories in a single mounting cavity, improving maintenance efficiency. Furthermore, a suspension 80 is set on the main frame 20, which can effectively reduce the vibration transmitted by the frame and improve the vibration reduction effect of the module.
