[0033] Reference below Figure 1-Figure 6 An electric drive assembly 100 according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 6 As shown, the electric drive assembly 100 according to the embodiment of the present utility model includes: a shell body 10 and a heat exchanger 30 .

[0035] An oil pan 20 is disposed at the bottom of the shell body 10 , and an accommodating space 22 is defined between the shell body 10 and the oil pan 20 . A heat exchanger 30 is located in the accommodating space 22 , and the heat exchanger 30 is suitable for dissipating heat from the lubricating medium in the shell body 10 .

[0036] It should be noted that the heat exchanger 30 is located in the accommodating space 22 defined by the shell body 10 and the oil pan 20, so that the heat exchanger 30 will be integrated inside the electric drive assembly 100, so that the overall electric drive assembly 100 can be made smaller, thereby realizing the miniaturized design of the electric drive system. At the same time, when the heat exchanger 30 is located in the accommodating space 22, the use of connecting pipelines can be reduced, thereby further reducing the volume of the electric drive assembly 100 and achieving a certain degree of lightweight.

[0037] According to the electric drive assembly 100 of the embodiment of the utility model, the heat exchanger 30 is arranged in the accommodating space 22 between the shell body 10 and the oil pan 20, so that the electric drive assembly 100 can be made smaller, thereby realizing the miniaturized design of the electric drive assembly 100. At the same time, the heat exchanger 30 in the accommodating space 22 can also reduce the use of connecting pipes, thereby further reducing the volume of the electric drive assembly 100, thereby achieving a certain degree of lightweight, and making the electric drive assembly 100 easier to install.

[0038] In some embodiments, Figure 1-Figure 3 As shown, the heat exchanger 30 is connected to the housing body 10 and / or the oil sump 20 .

[0039] It should be noted that the heat exchanger 30 is connected to the shell body 10 and / or the oil pan 20, so that the heat exchanger 30 can be more stable when the accommodating space 22 is set, so that the heat exchanger 30 is not easy to shake in the accommodating space 22, thereby affecting the heat dissipation of the lubricating medium.

[0040] For example, the heat exchanger 30 can be connected to the shell body 10, or to the oil pan 20, or can be connected to both the shell body 10 and the oil pan 20. Preferably, in the present embodiment, the heat exchanger 30 is connected to the oil pan 20. After the heat exchanger 30 is connected to the oil pan 20, it is installed as a whole below the shell body 10, thereby making the installation of the heat exchanger 30 easier.

[0041] Thus, the heat exchanger 30 is connected to the shell body 10 and / or the oil pan 20 , which can make the heat exchanger 30 more stable after being arranged in the accommodating space 22 , and can also facilitate the installation of the heat exchanger 30 .

[0042] In some embodiments, Figure 4-Figure 6 As shown, at least one oil guide port 31 is formed on the shell of the heat exchanger 30 , and the oil guide port 31 is suitable for connecting the shell body 10 and the oil pan 20 .

[0043] It should be noted that the oil guide port 31 can connect the shell body 10 with the oil pan 20, that is, the oil guide port 31 can connect the two sides of the heat exchanger 30 in the direction of the flow of the lubricating medium, so that the lubricating medium flowing out of the shell body 10 can enter the oil pan 20 through the oil guide port 31 after flowing onto the heat exchanger 30, thereby facilitating the oil pan 20 to collect the lubricating medium, and then facilitating the subsequent entry of the lubricating medium into the heat exchanger 30.

[0044] Furthermore, in this embodiment, the oil guide port 31 can be constructed as a notch, such as an arc-shaped notch, so that when the lubricating medium flows on the heat exchanger 30 and flows through the arc-shaped notch, it can pass through the heat exchanger 30 through the arc-shaped notch and enter the oil pan 20.

[0045] Therefore, by setting the oil guide port 31 on the heat exchanger 30, the shell body 10 is connected with the oil pan 20, so that the lubricating medium flowing out of the shell body 10 can enter the oil pan 20 through the oil guide port 31 when flowing onto the heat exchanger 30, so that the oil pan 20 can collect the lubricating medium.

[0046] In some embodiments, Figure 4-Figure 6 As shown, a plurality of oil guide ports 31 are disposed on the peripheral edge of the heat exchanger 30 and the plurality of oil guide ports 31 are distributed at intervals.

[0047] It should be noted that by arranging a plurality of oil guide ports 31 on the heat exchanger 30, the efficiency of the lubricating medium entering the oil pan 20 is made higher. At the same time, the plurality of oil guide ports 31 are arranged on the peripheral edge of the heat exchanger 30 and are distributed at intervals. In this way, when the plurality of oil guide ports 31 are arranged on the heat exchanger 30, they will not occupy too much space of the heat exchanger 30 and are not easily affected in the heat exchange capacity of the heat exchanger 30. At the same time, the plurality of oil guide ports 31 are distributed at intervals, so that the lubricating medium on the heat exchanger 30 can have multiple paths to enter the oil pan 20, so that the oil pan 20 can collect the lubricating medium more efficiently.

[0048] For example, in this embodiment, four oil guide ports 31 are provided on the heat exchanger 30, and each oil guide port 31 is located at the middle position of a side of the heat exchanger 30, so that the lubricating medium can enter the oil pan 20 faster, thereby allowing the oil pan 20 to collect the lubricating medium faster.

[0049] Therefore, by arranging a plurality of oil guide ports 31 on the peripheral edge of the heat exchanger 30, the lubricating medium can enter the oil pan 20 more quickly, and the plurality of oil guide ports 31 are arranged at intervals so that the oil guide ports 31 on the heat exchanger 30 can have multiple paths to enter the oil pan 20, thereby making the oil pan 20 more efficient in collecting the lubricating medium.

[0050] In some embodiments, Figure 6 As shown, a guide groove 21 is provided in the oil pan 20 , and an oil inlet is provided on a side of the heat exchanger 30 facing the oil pan 20 , and the oil inlet extends into the guide groove 21 .

[0051] It should be noted that by providing a guide groove 21 in the oil pan 20, the lubricating medium can have a flow direction when moving in the oil pan 20. At the same time, the oil inlet of the heat exchanger 30 faces the oil pan 20 and extends into the guide groove 21, so that the lubricating medium can flow to the oil inlet and enter the heat exchanger 30 to complete the heat exchange.

[0052] For example, in the present embodiment, a plurality of guide grooves 21 are provided in the oil pan 20, and each oil guide port 31 of the heat exchanger 30 is directly opposite to a guide groove 21, so that after the oil flows into the oil pan 20 from the oil guide port 31, it can directly flow to the oil inlet through the guide groove 21, and at the same time, the guide grooves 21 directly opposite to the oil guide port 31 will intersect at the center position of the oil pan 20, and the guide grooves 21 in contact with the oil inlet will connect the intersection and the oil inlet, so that the lubricating medium can be gathered together and then enter the oil inlet, so that more lubricating medium can enter the heat exchanger 30, thereby improving the heat exchange efficiency of the heat exchanger 30.

[0053] An oil drain plug 24 is also provided at the intersection of the guide grooves 21 , so that the lubricating medium in the oil pan 20 can be easily discharged, thereby facilitating the subsequent maintenance of the electric drive assembly 100 .

[0054] Thus, by providing the guide groove 21 in the oil pan 20, the lubricating medium in the oil pan 20 can be guided to the oil inlet of the heat exchanger 30, thereby improving the heat exchange efficiency of the heat exchanger 30. Figure 4-Figure 5 As shown, the heat exchanger 30 is provided with a first clamping portion 32 , and the shell body 10 or the oil pan 20 is provided with a second clamping portion 23 , and the first clamping portion 32 is clamped and matched with the second clamping portion 23 .

[0055] It should be noted that the first clamping portion 32 and the second clamping portion 23 are clamped together so that the heat exchanger 30 can be fixed on the shell body 10 or the oil pan 20. This reduces the use of bolts, thereby reducing the weight of the electric drive assembly 100, thereby achieving a lightweight design of the electric drive assembly 100. At the same time, the use of clamping fixation can also ensure the connection stability of the heat exchanger 30.

[0056] For example, in this embodiment, the first clamping portion 32 is configured as a buckle, and the second clamping portion 23 is arranged on the oil pan 20 and configured as a slot, so that the heat exchanger 30 can be well fixed on the oil pan 20, and the oil inlet can also be extended into the guide groove 21 of the oil pan 20. In this way, the oil pan 20 can be installed on the shell body 10 to complete the assembly of the electric drive assembly 100.

[0057] Therefore, the heat exchanger 30 is fixed by snapping together the first snap-fitting portion 32 and the second snap-fitting portion 23 on the shell body 10 or the oil pan 20 . At the same time, the use of bolts can be reduced through the snap-fit ​​connection, thereby reducing the weight of the electric drive assembly 100 and further realizing a lightweight design of the electric drive assembly 100 .

[0058] In some embodiments, Figure 4-Figure 6 As shown, the heat exchanger 30 is further provided with an oil outlet 33 , which is located on a side of the heat exchanger 30 facing the shell body 10 and is connected to an integrated oil circuit of the shell body 10 .

[0059] It should be noted that the oil outlet 33 of the heat exchanger 30 is located on the side of the heat exchanger 30 facing the shell body 10, and the oil outlet 33 is directly connected to the integrated oil circuit of the shell body 10, so that after the oil pan 20 is assembled on the shell body 10, the oil outlet 33 of the heat exchanger 30 can be connected to the integrated oil circuit, which makes the assembly of the electric drive assembly 100 easier. At the same time, the oil outlet 33 is directly connected to the integrated oil circuit of the shell body 10, which reduces the use of connecting pipelines, thereby reducing the weight of the electric drive assembly 100 and realizing the lightweight design of the electric drive assembly 100. At the same time, reducing the use of pipelines can also make the electric drive assembly 100 smaller, thereby realizing the miniaturized design of the electric drive assembly 100.

[0060] Among them, a sealing ring is arranged on the oil outlet 33 so that the oil outlet 33 has good sealing performance when connected with the integrated oil circuit, thereby ensuring the normal operation of the electric drive assembly 100.

[0061] Therefore, the oil outlet 33 of the heat exchanger 30 is directly connected to the integrated oil circuit of the shell body 10, which can reduce the use of connecting pipelines, thereby achieving a lightweight and miniaturized design of the electric drive assembly 100, and also making the assembly of the electric drive assembly 100 easier.

[0062] In some embodiments, Figure 4-Figure 6 As shown, the heat exchanger 30 is further provided with a water inlet 34 and a water outlet 35 , which are located on the side of the heat exchanger 30 facing the shell body 10 and are connected to the integrated water channel of the shell body 10 .

[0063] It should be noted that the water inlet 34 and the water outlet 35 of the heat exchanger 30 are located on the side of the heat exchanger 30 facing the shell body 10, and the water inlet 34 and the water outlet 35 are directly connected to the integrated water circuit of the shell body 10, so that after the oil pan 20 is assembled on the shell body 10, the water inlet 34 and the water outlet 35 of the heat exchanger 30 can be connected to the integrated water circuit, which makes the assembly of the electric drive assembly 100 easier. At the same time, the water inlet 34 and the water outlet 35 are directly connected to the integrated water circuit of the shell body 10, which reduces the use of connecting pipes, thereby reducing the weight of the electric drive assembly 100 and realizing the lightweight design of the electric drive assembly 100. At the same time, reducing the use of pipes can also make the electric drive assembly 100 smaller, thereby realizing the miniaturized design of the electric drive assembly 100.

[0064] Among them, sealing rings are provided on the water inlet 34 and the water outlet 35 so that the water inlet 34 and the water outlet 35 have good sealing when connected to the integrated water circuit, thereby ensuring the normal operation of the electric drive assembly 100.

[0065] Therefore, the water inlet 34 and the water outlet 35 of the heat exchanger 30 are directly connected to the integrated water circuit of the shell body 10, which can reduce the use of connecting pipes, thereby achieving a lightweight and miniaturized design of the electric drive assembly 100, and also making the assembly of the electric drive assembly 100 easier.

[0066] In some embodiments, Figure 4-Figure 6 As shown, the oil outlet 33 , the water inlet 34 and the water outlet 35 are located at the corners of the heat exchanger 30 and one of the oil outlet 33 , the water inlet 34 and the water outlet 35 is disposed at each corner.

[0067] It should be noted that the oil outlet 33, the water inlet 34 and the water outlet 35 are located at the corners of the heat exchanger 30, which can provide a certain guiding effect when the heat exchanger 30 is connected to the shell body 10, and each corner is provided with one of the oil outlet 33, the water inlet 34 and the water outlet 35, so that the oil outlet 33, the water inlet 34 and the water outlet 35 do not interfere with each other. At the same time, the oil outlet 33, the water inlet 34 and the water outlet 35 located at the corners can also make full use of the internal flow channel of the heat exchanger 30, thereby making the heat exchange efficiency of the heat exchanger 30 higher.

[0068] Therefore, the oil outlet 33, the water inlet 34 and the water outlet 35 are located at the corners and each corner is provided with one of the oil outlet 33, the water inlet 34 and the water outlet 35. This can play a certain guiding role when assembling the heat exchanger 30 and the shell body 10, and can also make full use of the internal flow channel of the heat exchanger 30, so that the heat exchange efficiency of the heat exchanger 30 is higher.

[0069] The utility model also provides a vehicle 1000 .

[0071] According to the vehicle 1000 of the embodiment of the utility model, in the electric drive assembly 100 thereon, by arranging the heat exchanger 30 in the accommodating space 22 between the shell body 10 and the oil pan 20, the electric drive assembly 100 can be made smaller, thereby realizing the miniaturized design of the electric drive assembly 100. At the same time, the heat exchanger 30 in the accommodating space 22 can also reduce the use of connecting pipelines, thereby further reducing the volume of the electric drive assembly 100, thereby achieving a certain degree of lightweight, and making the electric drive assembly 100 easier to install.
