[0033] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] With the development of science and technology, electric vehicles have gradually been widely used. In order to improve the user experience, electric vehicles are often provided with a variety of charging modes to meet the different needs of users.

[0036] In the related art, in the slow charging mode, the vehicle battery is often powered by a power conversion module integrated in the motor controller, wherein the motor controller is electrically connected to the external charging interface through a high-voltage wiring harness.

[0037] However, in general, the distance between the power supply interface of the motor controller and the external charging interface of the electric vehicle is relatively long, which will result in a long high-voltage wire harness. If the high-voltage wire harness cannot be effectively fixed, it is easy for the high-voltage wire harness to loosen during the driving of the vehicle and rub against the ground, causing damage, thus creating a high-voltage safety risk.

[0038] In order to solve the above technical problems, the present disclosure provides a sub-frame assembly, such as Figure 1 As shown, the subframe assembly includes a subframe 1, a motor controller 2 and a wiring harness assembly 3. Figure 2 As shown, the subframe 1 includes a first crossbeam 11, a second crossbeam 12, a third crossbeam 13 and a first longitudinal beam 14. The first crossbeam 11 and the second crossbeam 12 are fixedly connected to the first end and the second end of the first longitudinal beam 14 respectively. The third crossbeam 13 is fixedly connected to the first longitudinal beam 14 and is located between the first crossbeam 11 and the second crossbeam 12. The motor controller 2 is fixedly connected to the third crossbeam 13, and the side of the motor controller 2 has a first power supply interface 21. Figure 1 , Figure 2 As shown, the wiring harness assembly 3 includes a first wiring harness 31 and multiple brackets 32. The first wiring harness 31 is connected to the motor controller 2, the first crossbeam 11, the first longitudinal beam 14 and the second crossbeam 12 in sequence through the multiple brackets 32. The two ends of the first wiring harness 31 are respectively provided with a first connector 311 and a second connector 312. The first connector 311 is connected to the first power supply interface 21, and the second connector 312 is used to connect to the external power supply interface of the vehicle.

[0039] In the sub-frame assembly disclosed in the embodiment of the present disclosure, the first wire harness 31 can be fixed to the sub-frame 1 and the motor controller 2 by means of a plurality of brackets 32, thereby reducing the risk of the first wire harness 31 becoming loose during the driving of the vehicle, and further reducing the possibility of the first wire harness 31 being damaged due to friction with the ground and causing high-voltage safety risks.

[0040] In addition, in the related art, the power supply interface on the motor controller is often set at the bottom of the motor controller, which will cause the high-voltage wire harness connected to the power supply interface to be in a relatively low position, which will increase the probability of the high-voltage wire harness rubbing against the ground and causing it to be damaged. In comparison, in the embodiment of the present disclosure, the first power supply interface 21 is set on the side of the motor controller 2, which can make the overall height of the first wire harness 31 higher than the high-voltage wire harness in the related art. Compared with the related art, it can reduce the possibility of the first wire harness 31 rubbing against the ground and causing it to be damaged, thereby further reducing the high-voltage safety risk during vehicle driving.

[0041] like Figure 2 As shown, the height of the first power supply interface 21 is higher than the height of the first beam 11. In this way, the first wire harness 31 can be directly fixed on the top of the first beam 11, so that the first wire harness 31 can be supported by the first beam 11, thereby reducing the possibility of the first wire harness 31 being loosened and rubbing against the ground.

[0042] like Figure 1 As shown, the subframe 1 further includes a second longitudinal beam 15, the two ends of the second longitudinal beam 15 are respectively fixedly connected to the first cross beam 11 and the second cross beam 12, and the middle of the second longitudinal beam 15 is fixedly connected to the third cross beam 13, wherein the second longitudinal beam 15 and the first longitudinal beam 14 are respectively located on both sides of each cross beam. Further, the second longitudinal beam 15 is symmetrical with the first longitudinal beam 14, thereby ensuring that the second longitudinal beam 15 and the first longitudinal beam 14 are subjected to relatively uniform forces, thereby improving the stability of the subframe assembly.

[0043] The embodiment of the present disclosure does not limit the specific material and molding method of the multiple brackets 32.

[0044] For example, the plurality of brackets 32 are all made of metal material and formed by casting.

[0045] For another example, some of the multiple brackets 32 are made of metal material and are formed by casting, and another part of the brackets 32 are made of plastic and are formed by injection molding.

[0046] Optionally, the vehicle external power supply interface is disposed on the vehicle housing and is disposed at a position close to the second cross beam 12 so as to facilitate electrical connection between the second connector 312 and the vehicle external power supply interface.

[0047] The motor controller 2 provided in the embodiment of the present disclosure will be further described below in conjunction with the accompanying drawings.

[0048] In some embodiments, Figure 2 As shown, the motor controller 2 also has a second power supply interface 22, and the second power supply interface 22 is located on the side of the first power supply interface 21. The wiring harness assembly 3 also includes a second wiring harness 33, and the second wiring harness 33 is connected to the motor controller 2 and the first crossbeam 11 through a plurality of brackets 32. The two ends of the second wiring harness 33 are respectively provided with a third connector 331 and a fourth connector 332, and the third connector 331 is connected to the second power supply interface 22, and the fourth connector 332 is used to be electrically connected to the vehicle air conditioner.

[0049] In this way, the second wiring harness 33 can be fixed to the subframe 1 and the motor controller 2 through multiple brackets 32, thereby reducing the risk of the second wiring harness 33 loosening during the driving of the vehicle, and further reducing the possibility of the second wiring harness 33 being damaged by friction with the ground and causing high-voltage safety risks.

[0050] In addition, in the embodiment of the present disclosure, the second power supply interface 22 is arranged on the side of the first power supply interface 21, that is, the second power supply interface 22 is also arranged on the side of the motor controller 2. As a result, the overall height of the second wiring harness 33 can be higher than the high-voltage wiring harness in the related technology, thereby increasing the overall height of the second wiring harness 33, and further reducing the probability of the second wiring harness 33 rubbing against the ground and causing damage, thereby further reducing the high-voltage safety risk.

[0051] Optionally, the second wire harness 33 is used to supply power to the vehicle air conditioner.

[0052] In the disclosed embodiment, the wiring harness assembly 3 further includes an interlocking connector 37, which is used to connect to the vehicle central control and detect whether at least one connector in the first wiring harness 31 and the second wiring harness 33 is fully connected. Thus, it can be ensured that the connector is fully connected to the interface on the vehicle, thereby reducing the risk of high voltage during the use of the vehicle.

[0053] Optionally, the interlocking connector 37 has an interlocking terminal, and one or more connectors among the first connector 311, the second connector 312, the third connector 331 and the fourth connector 332 have an interlocking mating terminal, and the interlocking terminal is electrically connected to the interlocking mating terminal. After the connectors are connected properly, the interlocking terminal, the interlocking mating terminal and the vehicle central control can form a detection loop. At this time, the vehicle central control sends a signal that charging can be performed. Therefore, when the vehicle is charging, it can be ensured that the connector is well connected to each power supply interface on the vehicle, thereby reducing the high voltage risk during the vehicle charging process.

[0054] In some embodiments, in combination Figure 3 As shown, multiple brackets 32 include a first bracket 321, which is fixed to the motor controller 2 and located on the side of the first power supply interface 21 away from the second power supply interface 22, and the first bracket 321 is used to fix the first wiring harness 31 and the second wiring harness 33 to support the first wiring harness 31 and the second wiring harness 33.

[0055] A first bracket 321 is provided on the side of the first power supply interface 21. The first bracket 321 supports the first wire harness 31 and the second wire harness 33, and can maintain the fixed position of the first wire harness 31 and the second wire harness 33 at a relatively high position to prevent the first wire harness 31 and the second wire harness 33 from sagging due to excessive deflection, causing friction with the ground and damage, and the possibility of high-voltage safety risks. In addition, since the first bracket 321 is provided on the side of the first power supply interface 21, the first bracket 321 can support the first wire harness 31 and the second wire harness 33 at a relatively close position, thereby reducing the torque of the first wire harness 31 and the second wire harness 33 on the first bracket 321 due to their own weight, and further reducing the possibility of the first wire harness 31 and the second wire harness 33 sagging.

[0056] Optionally, the first bracket 321 is fixed on the housing of the motor controller 2 .

[0057] In some embodiments, Figure 3 As shown, the wire harness assembly 3 further includes a wire harness tube 34 , which is sleeved outside the first wire harness 31 and the second wire harness 33 .

[0058] In this way, the first wire harness 31 and the second wire harness 33 can be restrained by the wire harness tube 34, thereby preventing the first wire harness 31 and the second wire harness 33 from being distributed in a disorderly manner or even entangled with other equipment. Thus, the possibility of the first wire harness 31 and the second wire harness 33 interfering with other structures can be avoided.

[0059] Optionally, the wire harness tube 34 is made of insulating material and has a certain elasticity, thereby improving the stability of the wire harness tube 34 in restraining the first wire harness 31 and the second wire harness 33. For example, the wire harness tube 34 can be made of rubber material.

[0060] In some embodiments, Figure 3 As shown, the plurality of brackets 32 further include a second bracket 322 . The second bracket 322 is fixed to the first cross beam 11 and is fixedly connected to the cable harness tube 34 .

[0061] In this way, the wiring tube 34 can be fixed to the first cross beam 11 through the second bracket 322, that is, the first wire harness 31 and the second wire harness 33 can be fixed to the first cross beam 11 through the second bracket 322, thereby improving the stability of fixing the first wire harness 31 and the second wire harness 33, and further reducing the possibility of the first wire harness 31 and the second wire harness 33 getting loose.

[0062] In some embodiments, Figure 4 As shown, the second bracket 322 has a first harness portion 3221 and a second harness portion 3222. The first harness portion 3221 is located at the top of the first beam 11 and is fixedly connected to the first harness 31. The second harness portion 3222 is located at the side of the first beam 11 and is fixedly connected to the second harness 33.

[0063] Since the first wire harness 31 and the second wire harness 33 have different directions, two wire harness parts are provided on the second bracket 322, and the first wire harness 31 and the second wire harness 33 are fixed by the two wire harness parts respectively to prevent the first wire harness 31 and the second wire harness 33 from being entangled with other structures after being dispersed. In addition, the first wire harness part 3221 is arranged on the top of the first beam 11, that is, the first wire harness 31 can be arranged on the top of the first beam 11, so that the first wire harness 31 can be supported by the first beam 11, thereby reducing the possibility of the first wire harness 31 being loosened. In addition, since the power supply port of the vehicle air conditioner is often arranged near the first beam 11 and away from the lower side of the second beam 12, the second wire harness part 3222 is arranged on the side of the first beam 11 to fix the bending of the second wire harness part 3222.

[0064] Optionally, the first cable tie portion 3221 and the second cable tie portion 3222 may be, for example but not limited to, cable ties.

[0065] In some embodiments, in combination Figure 1 , Figure 4 As shown, the first end of the first longitudinal beam 14 protrudes from the first cross beam 11 , and the plurality of brackets 32 further include a third bracket 323 . The third bracket 323 is fixed to the first end and fixedly connected to the first wiring harness 31 .

[0066] In this way, the first wire harness 31 can be fixed to the first end of the first longitudinal beam 14, so as to bend the first wire harness 31. Moreover, after the first wire harness 31 is fixed by the third bracket 323, it can be directly fixed to the top of the first longitudinal beam 14, so that the first wire harness 31 is supported by the first longitudinal beam 14, thereby reducing the possibility of bending of the first wire harness 31.

[0067] In some embodiments, the plurality of brackets 32 further include a fourth bracket 324 , which is fixed to the second end of the first longitudinal beam 14 and fixedly connected to the first wire harness 31 .

[0068] In this way, after the first wire harness 31 leaves the top of the first longitudinal beam 14, it needs to be fixedly connected to the second cross beam 12, and the first wire harness 31 is fixed by the fourth bracket 324 located at the second end of the first longitudinal beam 14, so that the first wire harness 31 can be guided. In addition, the first wire harness 31 is fixed to the second end through the fourth bracket 324, which can also strengthen the fixing effect of the first wire harness 31 to prevent the first wire harness 31 from loosening.

[0069] In some embodiments, in combination Figure 4 As shown, the plurality of brackets 32 further include a fifth bracket 325 . The fifth bracket 325 is fixed to the second cross beam 12 and fixedly connected to the second connector 312 .

[0070] In this way, the second connector 312 can be fixed to prevent the electrical connection between the second connector 312 and the vehicle's external charging interface from loosening, thereby ensuring the stability of the electrical connection between the second connector 312 and the vehicle's external charging interface.

[0071] In some embodiments, Figure 3 As shown, the wiring harness assembly 3 also includes a pipe clamp 35, which is fixed to the first longitudinal beam 14 and fixedly connected to the first wiring harness 31. Figure 4 As shown, the tube clamp 35 has a tube binding portion 351, and the tube binding portion 351 is used to fix the liquid tube.

[0072] In this way, by means of the pipe clamp 35 fixed on the first longitudinal beam 14, on the one hand, the first wire harness 31 can be fixed to the first longitudinal beam 14 by means of the pipe clamp 35, so as to strengthen the fixing effect between the first wire harness 31 and the first longitudinal beam 14, so as to prevent the first wire harness 31 from loosening and hanging from the side of the top of the first longitudinal beam 14 when subjected to lateral force, thereby causing the first wire harness 31 to loosen from the fixing of other brackets 32; on the other hand, the pipe clamp 35 has a bundle tube portion 351, which can fix the liquid pipe on the vehicle, thereby fixing the liquid pipe to the subframe 1, thereby preventing the liquid pipe from loosening, and improving the stability of vehicle operation. Therefore, by means of the pipe clamp 35, the stability of the whole vehicle operation can be improved in different aspects.

[0073] Optionally, the tube binding portion 351 may be, for example but not limited to, a cable tie. In this way, the fixing efficiency of the liquid tube can be achieved more conveniently.

[0074] Alternatively, the liquid pipe may be, for example but not limited to, a vehicle water pipe assembly.

[0075] In some embodiments, Figure 3 As shown, the wiring harness assembly 3 also includes a first threaded staple 36, which is fixed to the first longitudinal beam 14 and is located between the fourth bracket 324 and the pipe clamp 35. The first threaded staple 36 is used to be fixedly connected to the first wiring harness 31 to strengthen the fixing effect of the first wiring harness 31 and the first longitudinal beam 14, thereby improving the stability of the fixing of the first wiring harness 31.

[0076] In some embodiments, Figure 4 As shown, the wiring harness assembly 3 also includes a second threaded staple 38, which is fixed to the second cross beam 12 and located between the fourth bracket 324 and the fifth bracket 325. The first threaded staple 36 is used to be fixedly connected to the first wiring harness 31 to fix the first wiring harness 31 on one side of the second cross beam 12, so that after the first wiring harness 31 leaves the first longitudinal beam 14, the deflection thereof is large due to the long distance between the first longitudinal beam 14 and the fifth bracket 325, and the situation of sagging can be reduced. In this way, the risk of the first wiring harness 31 being loosened during the driving of the vehicle can be further reduced, and the possibility of the first wiring harness 31 being damaged due to friction with the ground and causing high-voltage safety risks can be reduced.

[0077] Based on the same concept, an embodiment of the present disclosure further provides a vehicle, the vehicle comprising the subframe assembly provided by the first aspect and possible implementations thereof.
