[0035] In order to more clearly explain the above-mentioned purposes, features and advantages of the present application, the specific implementation methods of the present application are described in detail in this section in conjunction with the accompanying drawings. In addition to the various implementation methods described in this section, the present application can also be implemented in other different ways. Without violating the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and substitutions, so the present application is not limited by the specific embodiments disclosed in this section. The scope of protection of the present application shall be subject to the claims.

[0036] like Figures 3 to 8As shown, the embodiment of the present application provides a bracket assembly for a hybrid power module and a hybrid power module for a vehicle including the bracket assembly. The hybrid power module for a vehicle may include a bracket 1, a motor rotor, a motor stator 2, a motor shaft and a connecting frame 3. The motor rotor, the motor stator 2, the motor shaft, etc. may constitute a motor. The hybrid power module for a vehicle may also include, for example Figure 1 The clutch shown in the figure can be installed on the radial inner side of the motor rotor. The bracket assembly for the hybrid power module according to the embodiment of the present application can include a bracket 1 and a connecting frame 3.

[0037] The bracket 1 may be a single-piece structure, and includes a bearing support portion 11 , a motor stator support portion 12 and a transition connection portion 13 .

[0038] like Figure 3 and Figure 4 As shown, the bearing support portion 11 and the motor stator support portion 12 may be annular extending along the axial direction A and the circumferential direction C of the motor, and the transition connection portion 13 may be annular extending along the radial direction R and the circumferential direction C of the motor, and the bearing support portion 11 and the motor stator support portion 12 are connected through the transition connection portion 13. The bearing support portion 11 and the motor stator support portion 12 may extend from the radial inner end portion and the radial outer end portion of the transition connection portion 13 to the same side along the axial direction A, respectively. The bearing support portion 11 is parallel to the motor stator support portion 12, and the bearing support portion 11 is located radially inside the motor stator support portion 12.

[0039] The motor rotor can be connected to the motor shaft, and the motor shaft can rotate relative to the motor stator 2. The motor shaft can be sleeved with a bearing 4, and the bearing 4 can be installed on the radial inner side of the bearing support part 11. The bearing support part 11 and the outer ring of the bearing 4 cooperate, and the motor stator 2 can be located on the radial inner side of the motor stator support part 12.

[0040] The bearing support portion 11, the motor stator support portion 12 and the transition connection portion 13 can be integrally formed, that is, the bracket 1 can be a single-piece part, rather than a combined component formed by two or more parts connected together by welding, bolting, riveting, etc. For example, the bracket 1 can be integrally formed by a stamping or spinning process, preferably by a spinning process. Compared with stamping, the mold cost used for spinning is lower. Figure 1 and Figure 2 Compared with the separately formed stator frame 100 and bearing frame 200 shown, the integrally formed bracket 1 of the present application has a higher material utilization rate and can generate less waste and save raw materials compared with the solution of processing them separately and then assembling them together.

[0041] like Figure 3 and Figure 4As shown, different parts of the bracket 1 may have different thicknesses, for example, the thickness of the transition connection portion 13 may be greater than the thickness of the bearing support portion 11 and the thickness of the motor stator support portion 12. Different parts of the bracket 1 may have different thicknesses by using a spin forming process.

[0042] The connecting frame 3 can be detachably connected to the transition connection portion 13, and the connecting frame 3 can be provided with an adapter component mounting hole. The connecting frame 3 can be used to connect the vehicle hybrid power module to the adapter component (such as a gearbox housing). The present application does not limit the specific shape of the connecting frame 3, and the specific shape of the connecting frame 3 can be adjusted according to the adapter component, for example Figure 7 and Figure 8 Two types of connecting brackets 3 are shown as examples.

[0043] like Figure 7 As shown, the connecting frame 3 may be a fan-shaped flat plate, and the connecting frame 3 may be provided with holes for bolt connection or riveting. Figure 8 As shown, the connecting frame 3 can be a strip-shaped curved plate, and the connecting frame 3 can include a first section 31, a bent connecting section 32, and a second section 33. The first section 31 extends along the radial direction of the motor as a whole, and the first section 31 can be bent or straight. The second section 33 extends along the radial direction of the motor as a whole, and the length of the second section 33 along the radial direction of the motor can be smaller than the length of the first section 31 along the radial direction of the motor. The bent connecting section 32 connects the first section 31 and the second section 33 together, and the bent connecting section 32 can make the first section 31 and the second section 33 at least partially staggered in the radial direction of the motor. Similarly, Figure 8 The connecting bracket 3 shown can be appropriately provided with holes for bolting or riveting.

[0044] The connecting frame 3 can be made by stamping, which has low cost. The detachable connecting frame 3 is easy to replace. By replacing the connecting frame 3, the vehicle hybrid power module can adapt to adapter components of different specifications, and the same vehicle hybrid power module can be adapted to different adapter components, which has high flexibility.

[0045] like Figures 4 to 6 As shown, the transition connection portion 13 may be provided with a connection frame mounting hole 131, and a plurality of connection frame mounting holes 131 may be provided along the circumferential direction C of the bracket 1, and the connection frame 3 may be mounted on the connection frame mounting hole 131 by means of bolts 31. There may be a plurality of connection frames 3, and the plurality of connection frames 3 are arranged along the circumferential direction C of the bracket 1. By connecting a plurality of connection frames 3 to the bracket 1, the size of each connection frame 3 may be small, and the structure may be simplified, so that the connection frame 3 may be manufactured in a low-cost manner. The connection frame 3 is easy to modify, and the modification cost is low.

[0046] It is understandable that the bolt 31 here can be a sealing bolt. The connecting frame 3 can also be mounted to the bracket 1 by riveting, welding, etc.

[0047] The rotor position sensor 5 may be connected to the transition connection portion 13, and the rotor position sensor 5 may face the motor rotor or the rotor bracket (used to connect the motor rotor and the motor shaft). More specifically, the stator portion of the rotor position sensor 5 may be connected to the transition connection portion 13. The transition connection portion 13 may be provided with a sensor mounting hole 132, and the sensor mounting hole 132 may be located radially inward of the connecting frame mounting hole 131.

[0048] Here, the sensor installation hole 132 may be a blind hole opened toward the inner side of the bracket 1 (the inner side of the hybrid power module), so that oil leakage at the sensor installation hole 132 can be avoided.

[0049] like Figure 3 and Figure 4 As shown, the outer peripheral surface of the bracket 1 can be provided with a sealing ring installation groove 133, and the sealing ring installation groove 133 can be located at the connection transition position between the motor stator support part 12 and the transition connection part 13. The sealing ring installation groove 133 is used to install a sealing ring, and the sealing ring can seal the cavity containing the oil used to cool the hybrid power module for the vehicle.

[0050] The bracket 1 can be made of steel. When manufacturing the bracket 1, the raw steel can be cut into a disc of suitable size, and then the disc-shaped steel sheet can be installed on a spinning machine. The steel sheet is deformed and stretched by the spinning machine to form a blank with a three-dimensional shape. Finally, the blank is machined. The size accuracy of the blank after spinning is low. The outer dimensions of the bracket 1 are accurate through machining, and some holes (such as the connecting frame mounting hole 131, the sensor mounting hole 132), grooves (such as the sealing ring mounting groove 133), chamfers and other features can also be processed.

[0051] The bracket assembly for a hybrid power module and the hybrid power module for a vehicle of the present application have the following beneficial effects.

[0052] (1) The bracket 1 is integrally formed to increase material utilization, reduce waste generated during the manufacturing process, and has a simple structure and good reliability.

[0053] (2) Since the mold cost used in spin forming is low, the cost of the bracket can be reduced.

[0054] (3) The connecting frame 3 that can be detachably mounted to the bracket 1 is easy to replace. By replacing the connecting frame 3, the vehicle hybrid power module can be adapted to adapter components of different specifications, which has high flexibility.
