An installation part for connecting to the vehicle body is arranged on the bottom plate assembly, and a wiring harness fixing part for fixing the wiring harness is arranged on the support plates and the bottom plate assembly.

[0007] According to the above technical means, the controller is fixed by the integrally formed body. The bracket is connected to the vehicle body through the installation part, the overlapping parts of the controller are supported by the support surfaces, and the wiring harness of the controller for connecting to the vehicle body is fixed by the wiring harness fixing part on the bracket, greatly reducing the space occupied in the front cabin of the vehicle body. The integrally formed bracket eliminates the assembly process and improves the assembly accuracy with the vehicle body and the control.

[0008] Further, the two ends of the controller along the first direction have protruding parts, and avoiding grooves are arranged on the sides of the two support plates facing the accommodation space for avoiding the protruding parts of the controller.

[0009] According to the above technical means, a part of the controller is located in the accommodation space. The supporting surface supports and fixes the lapping part of the controller, and the avoiding groove on the support plate avoids the protruding part of the controller, further reducing the occupied space of the motor control assembly.

[0039] In the related art, the motor controller assembly includes a controller and a bracket. The bracket is formed by welding and splicing multiple components, and the utilization rate of the space layout is relatively low. There are overlapping edges between the components of the bracket, which need to be connected by welding points. The investment cost of the tooling is high, and the accuracy of the bracket formed by welding and splicing is poor, affecting the assembly accuracy with the vehicle body and the controller.

[0040] As Figure 1-8 shown, this embodiment proposes a bracket for supporting the controller 1. The controller 1 has a wire harness 11 for connecting to the vehicle body, and the two ends of the controller 1 along the first direction X have overlapping portions 12; the bracket includes an integrally formed body 2. The body 2 includes two support plates 21 arranged at intervals along the first direction X and a bottom plate assembly 22 connected to the two support plates 21. An accommodation space for accommodating the controller 1 is formed between the two support plates 21. The ends of the two support plates 21 away from the bottom plate assembly 22 are respectively bent toward the side away from the accommodation space to form support surfaces 211 for supporting the overlapping portions 12 of the controller 1. An installation portion 221 for connecting to the vehicle body is provided on the bottom plate assembly 22, and a wire harness fixing portion 23 for fixing the wire harness 11 is provided on the support plates 21 and the bottom plate assembly 22.

[0041] In this application, the controller 1 is fixed by the integrally formed body 2. The bracket is connected to the vehicle body through the installation portion 221. The overlapping portions 12 of the controller 1 are supported by the support surfaces 211, and the wire harness 11 of the controller 1 for connecting to the vehicle body is fixed by the wire harness fixing portion 23 on the bracket, greatly reducing the space occupied in the front cabin of the vehicle body. The integrally formed bracket eliminates the assembly process and improves the assembly accuracy with the vehicle body and the control.

[0042] In some embodiments, both ends of the controller 1 in the first direction X have protruding portions 13, and avoiding grooves 214 are provided on one side of the two support plates 21 facing the accommodation space for avoiding the protruding portions 13 of the controller 1.

[0043] In this application, a part of the controller 1 is located in the accommodation space. The lapping portion 12 of the controller 1 is supported and fixed by the support surface 211, and the protruding portion 13 of the controller 1 is avoided through the avoiding groove on the support plate 21, further reducing the occupied space of the motor control assembly.

[0044] Specifically, a reserved notch 215 is provided at the outer edge of the support surface 211, reserving space for the engine oil detection caliper.

[0045] In some embodiments, a hemming structure 212 is provided on the support surface of at least one support plate 21; one end of the bottom plate assembly 22 in the second direction Y is provided with a stepped surface 222, and the stepped surface 222 protrudes toward the accommodation space so that there is a gap between the stepped surface 222 and the vehicle body; a wire harness fixing portion 23 is provided on the stepped surface 222, the hemming structure 212 and the support plate 21; wherein, the first direction X intersects with the second direction Y, and a first avoiding notch 213 for avoiding the stepped surface 222 is provided at one end of the support plate 21 adjacent to the stepped surface 222.

[0046] Specifically, there is a gap between the stepped surface 222 and the vehicle body, and the height of the gap is 20 mm - 25 mm. The stepped surface 222 is an integrated wire protection box installation point and air filter installation point, and the integrated wire protection box can be installed below the stepped surface 222, making the structure more compact.

[0047] In this application, the hemming structure 212 is located outside the controller 1. The three-phase power wire harness 111 assembly of the controller 1 is fixed through the wire harness fixing portion 23 on the hemming structure 212, the engine wire harness assembly 112 and the PTC input wire harness assembly 113 of the controller 1 are fixed through the wire harness fixing portion 23 on the support plate 21, and the integrated wire protection box installation point and the air filter are fixed through the wire harness fixing portion 23 on the stepped surface 222, ensuring the reliability of the wire harness 11 connection.

[0048] Specifically, the wire harness fixing portion 23 is a mounting hole or a mounting post. The wire hoop is fixed through the mounting hole and the mounting post, and the wire harness 11 is fixed through the wire hoop.

[0049] In some embodiments, a bending portion 223 bent toward the side away from the accommodation space is provided at one end of the bottom plate assembly 22 away from the stepped surface 222, and the wire harness fixing portion 23 is provided on the bending portion 223.

[0050] In this application, the bent portion is bent towards the vehicle body direction for fixing the high-voltage power line harness assembly 114 and the engine compartment wire harness assembly 115.

[0051] Specifically, on one side of the bottom plate assembly 22 adjacent to the stepped surface 222, a second avoidance notch 27 and a third avoidance notch 28 are provided. The second avoidance notch 27 is used to avoid the engine outlet water pipe 116, and the third avoidance space provides an assembly space for the connecting electrical pipeline 117 of the controller 1.

[0052] In some embodiments, at least one connecting rib 24 communicating the bottom plate assembly 22 and the two support plates 21 is provided on the body 2. The connecting rib 24 includes a first reinforcing rib 241 provided on the bottom plate assembly 22 and two second reinforcing ribs 242 communicating with both ends of the first reinforcing rib 241. The first reinforcing rib 241 extends along the first direction X, and the two second reinforcing ribs 242 are respectively provided on the two support plates 21.

[0053] In this application, the outer shape section of the bracket is a U-shaped structure. By means of the connecting rib 24 connecting the bottom plate assembly 22 and the support plate 21, the strength of the bracket can be improved.

[0054] Specifically, the first reinforcing rib 241 of the connecting rib 24 is arranged along the first direction X, so that the bracket will not be bent along the second direction Y. The U-shaped bracket extends along the first direction X, and the strength in the first direction X can be ensured through its own structure. The second reinforcing rib 242 on the support plate 21 is directly connected to the first reinforcing rib 241 and is integrally formed by stamping to ensure the strength between the support plate 21 and the bottom plate assembly 22.

[0055] In some embodiments, the bottom plate assembly 22 is provided with a mounting rib 25 protruding towards the side away from the accommodation space. The mounting portion 221 is a mounting hole provided at the mounting rib 25 for connecting to the vehicle body; the connecting rib 24 protrudes towards the accommodation space.

[0056] In this application, the mounting rib 25 protrudes towards the vehicle body side, which is convenient for fitting with the vehicle body so that the mounting portion 221 can be fixed to the vehicle body. The protruding direction of the mounting rib 25 is opposite to the protruding direction of the connecting rib 24. The concave-convex structural design further improves the overall strength of the bracket.

[0057] Specifically, the mounting rib 25 is recessed downward, so that after the connecting bolt connects the bracket and the vehicle body, the connecting bolt is located in the recessed groove of the mounting rib 25 and will not affect the assembly of the controller 1.

[0058] Furthermore, the mounting rib 25 includes a third reinforcing rib 251 and a fourth reinforcing rib 252, and the third reinforcing rib 251 and the fourth reinforcing rib 252 are respectively located on both sides of the connecting rib 24.

[0059] In this application, the third reinforcing rib 251 and the fourth reinforcing rib 252 located on both sides of the connecting rib 24 are connected to the vehicle body to ensure the fixing effect between the bracket and the vehicle body.

[0060] Specifically, the fourth reinforcing rib 252 adopts a circular structure to increase the contact area with the vehicle body as much as possible, and then is connected to the vehicle body through the mounting holes at the fourth reinforcing rib 252.

[0061] In some embodiments, the third reinforcing rib 251 includes a first extension portion 2511 and a second extension portion 2512. One end of the first extension portion 2511 extends to one of the support plates 21, and the other end extends to the other support plate 21; the bottom plate assembly 22 further includes a reverse protruding rib 26 disposed between the first extension portion 2511 and the second extension portion 2512, and the reverse protruding rib 26 protrudes toward the side of the accommodation space.

[0062] In this application, both ends of the first extension portion 2511 of the third reinforcing rib 251 extend to the two support plates 21 respectively, serving the purpose of strengthening the bottom plate assembly 22. One end of the second extension portion 2512 is bent upward for connection with the vehicle body. The first extension portion 2511 and the second extension portion 2512 are separated by the reverse protruding rib 26 to prevent the length of the third reinforcing rib 251 along the second direction Y from being too long and affecting the strength, further ensuring the strength of the bottom plate assembly 22.

[0063] Specifically, a space for arranging the engine wire harness assembly 112 is reserved between the end of the second extension portion 2512 and the support plate 21; the second extension portion 2512 extends outward away from the accommodation space, so that the engine outlet pipe 116 passes under the controller 1.

[0064] The bracket of this application fixes the controller 1 through the integrally formed body 2. The bracket is connected to the vehicle body through the mounting portion 221, supports the overlapping portion 12 of the controller 1 through the support surface 211, and fixes the wire harness 11 for connecting the controller 1 to the vehicle body through the wire harness fixing portion 23 on the bracket, greatly reducing the space occupied in the front cabin of the vehicle body. The integrally formed bracket eliminates the assembly process and improves the accuracy of assembly with the vehicle body and the controller.

[0065] The embodiment of this application provides a motor controller assembly, including the controller 1 and the above-mentioned bracket.

[0066] Specifically, the motor controller assembly further includes a cover body covering the controller 1, which will not be elaborated here.
