Description

Technical Field

[0001] The invention relates to the technical field of automobile component structures, and in particular to an integrated structure of wheel hub motor wheel side pipelines and an automobile. Background Art

[0002] In the field of new energy vehicle technology, wheel hub motors are widely used as a new structure. In the wheel end layout, the high and low voltage wiring harnesses of the wheel hub motor and the outlet of the cooling pipes are difficult to arrange in order to avoid the damping shock absorbers of the McPherson suspension. In addition, the front independent suspension is affected by the steering rod and jumps up and down. The wheel hub motor itself is restricted by the installation space of the brake caliper or brake drum, which makes the matching space between the wheel hub motor and the McPherson suspension quite compact, resulting in interference between the high and low voltage wiring harnesses and cooling pipes and other wheel hub motor wiring harnesses and the surrounding moving parts.

[0003] In order to solve this problem, there is an existing technology that proposes that a double wishbone front independent suspension can be matched with a hub motor. The hub motor wiring harnesses such as the high and low voltage wiring harnesses, cooling pipes and lubrication pipes of the hub motor body can be arranged along the upper control arm or lower control arm of the double wishbone suspension. In this way, the pipelines can be well fixed to avoid the swing of the pipelines during the up and down jumping of the suspension system. At the same time, by arranging the brake caliper and the steering rod relative to each other, the interference of the steering rod with the pipeline can be avoided, thereby ensuring the stability and rationality of the wiring harness layout structure.

[0004] However, this structure also has some problems. This structure directly fixes the pipeline on the control arm. Although this method of fixing the wiring harness can solve the problem of wiring harness swinging, in actual application, because the pipeline needs to adapt to the wheel hop and steering functions, if the pipeline is completely fixed on the control arm, then during wheel hop and steering, the pipeline and the wheel end joint will have relative displacement through the fixed connection between the pipeline and the suspension, and the pipeline will be pulled, which can easily cause damage to the pipeline or fall off.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0080] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0081] The present application relates to an integrated structure of wheel-side pipelines of a hub motor, involving a wheel rim, a hub motor and a suspension. The present application fixes the pipelines to the hub motor and the suspension through a fixed structure, and leaves a telescopic margin for the pipelines to adapt to wheel hop and / or steering between the hub motor and the suspension, so that the pipelines are not subjected to pulling during actual use, and damage to the pipelines caused by pulling the pipelines due to wheel hop and / or steering will not occur, thereby improving the service life of the pipelines.

[0082] Specifically, Figures 1 to 30 As shown, a wheel hub motor wheel side pipeline integrated structure of the present application includes a rim 1, a hub motor and a suspension, the hub motor includes an outer rotor shell 2 fixedly connected to the rim 1 and a stator shell 5 fixedly connected to the suspension, a high-voltage wiring harness interface 51, a low-voltage wiring harness interface 52 and a water cooling pipeline interface 53 are provided at one end of the stator shell 5 close to the vehicle body, the high-voltage wiring harness interface 51 is connected to the high-voltage wiring harness, and the low-voltage wiring harness interface 52 is connected to the low-voltage wiring harness; the water cooling pipeline interface 53 is connected to a cooling water pipe, a plurality of fixing structures for fixing the high-voltage wiring harness, the low-voltage wiring harness and the cooling water pipe are provided between the stator shell 5 and the suspension; the high-voltage wiring harness, the low-voltage wiring harness and the cooling water pipe between adjacent fixing structures have a telescopic margin to adapt to wheel bouncing and / or steering.

[0083] like Figure 1 , 15As shown in Figures 28, a high-voltage wiring harness is connected to the high-voltage wiring harness interface 51, one end of which is connected to the high-voltage wiring harness interface 51 on the stator housing 5, and the other end is connected to the vehicle-mounted MCU; a low-voltage wiring harness is connected to the low-voltage wiring harness interface 52, one end of which is connected to the low-voltage wiring harness interface 52 on the stator housing 5, and the other end is connected to the in-vehicle communicator; a cooling water pipe is connected to the water-cooling pipe interface 53, one end of which is connected to the water-cooling pipe interface 53 on the stator housing 5, and the other end is connected to the radiator assembly or the charger water pipe assembly; a fixing structure for fixing the high-voltage wiring harness, the low-voltage wiring harness and the cooling water pipe is provided between the stator housing 5 and the suspension.

[0084] When installing the stator housing 5 facing the vehicle body, first fix the stator housing 5 to the vehicle body suspension, then connect the wiring harness and water pipe structure in sequence, connect one end of the high-voltage wiring harness to the high-voltage wiring harness interface 51 on the stator housing 5, and the other end to the vehicle-mounted MCU, and then use the fixed structure to fix the high-voltage wiring harness to avoid shaking or friction with the ground during use; connect one end of the low-voltage wiring harness to the low-voltage wiring harness interface 52 on the stator housing 5, and the other end to the in-vehicle communicator, and similarly use the fixed structure to fix the low-voltage wiring harness; connect one end of the cooling water pipe to the water cooling pipe interface 53 on the stator housing 5, and the other end to the radiator assembly or the charger water pipe assembly, and use the fixed structure to fix the cooling water pipe; complete the connection between the stator housing 5 and the suspension as well as the wiring harness and water pipe.

[0085] The high-voltage harness interface 51, the low-voltage harness interface 52, and the water-cooling pipe interface 53 of the present application have different directions in addition to the different connection objects. Fig.28 As shown, the low-voltage harness interface 52 is along the tangential direction of the circumference of the stator housing 5, and the high-voltage harness interface 51 and the water-cooling pipeline interface 53 are along the axial direction parallel to the stator housing 5. Through this arrangement, the harness that is easy to be entangled can be arranged from different directions. In addition, the positions of the high-voltage harness interface 51, the low-voltage harness interface 52 and the water-cooling pipeline interface 53 on the stator housing 5 are also different and do not overlap with each other.

[0086] The wheel assembly structure used in the present application is the same, that is, the stator housing 5 and the rim 1 structure of the front and rear wheels are the same, but the suspension structure connected to the stator housing 5 is different. Considering that the front wheels of the vehicle need to have a steering function, while the rear wheels do not need to steer, the suspension of the vehicle of the present application is divided into two types, namely, the front suspension 3 and the rear suspension 4. Figures 1 to 14As shown, the front suspension 3 includes a steering knuckle 31 connected to the stator housing 5, and also includes a shock absorber 33, a vehicle body longitudinal beam 32 and a front bracket 34 structure; the rear suspension 4 includes a joint head 41 fixedly connected to the stator housing 5, and also includes a rear vehicle body longitudinal beam spring arm 42 and a rear bracket 43. In actual application, the front suspension and the rear suspension also involve many other structural components, but except for the above components, other components are not connected to the pipeline structure of this application, and therefore are not within the scope of this application.

[0087] Because the functions of the front suspension 3 and the rear suspension 4 are different, and the connection forms with the stator housing 5 are different, the fixing structure of the front wheel wiring harness and water pipe pipeline of the present application is different from the fixing structure of the rear wheel wiring harness and water pipe pipeline. That is, the fixing structure of the present application includes a front suspension fixing bracket for fixing the high-voltage wiring harness, low-voltage wiring harness and cooling water pipe between the front suspension and the stator housing 5 of the front wheel, and a rear suspension fixing bracket for fixing the high-voltage wiring harness, low-voltage wiring harness and cooling water pipe between the rear suspension and the stator housing 5 outside the rear wheel.

[0088] In a further embodiment of the present application, the front suspension fixing bracket is optimized. Specifically, Figures 2 to 6 As shown, the front suspension fixing bracket includes a plurality of first high-voltage wire harness fixing brackets 38, which are arranged in sequence and spaced apart along the extension direction of the front suspension high-voltage wire harness 35, and are used to fix the front suspension high-voltage wire harness 35 to the steering knuckle 31 and the vehicle body longitudinal beam 32 in the front suspension.

[0089] like Figures 2 to 6As shown, there are three first high-voltage harness fixing brackets 38 of the present embodiment, which are respectively used to fix the front suspension high-voltage harness 35 to the steering knuckle 31, to fix the front suspension high-voltage harness 35 to the front end position of the vehicle body longitudinal beam 32, and to fix the front suspension high-voltage harness 35 to the rear end position of the vehicle body longitudinal beam 32, that is to say, there are five fixing points corresponding to the front suspension high-voltage harness 35, namely the stator housing 5, the steering knuckle 31, the front end position of the vehicle body longitudinal beam 32, the rear end position of the vehicle body longitudinal beam 32 and the vehicle-mounted MCU (the interface corresponding to the vehicle-mounted MCU at the front of the vehicle body). The front suspension high-voltage harness 35 between the steering knuckle 31 and the stator housing 5 is very short, and the structure is relatively stable and not prone to shaking; the front suspension high-voltage harness 35 between the steering knuckle 31 and the front end position of the vehicle body longitudinal beam 32 is relatively long, and this part of the front suspension high-voltage harness 3 5 extends approximately in the Y direction of the vehicle body, and needs to cope with wheel hop and steering. Therefore, the front suspension high-voltage wire harness 35 between the two first high-voltage wire harness fixing brackets 38 of the steering knuckle 31 and the vehicle body longitudinal beam 32 in this embodiment is a bending structure with a telescopic margin to adapt to wheel hop and steering. The telescopic margin can avoid the problem of interference during steering and wheel hop. The front suspension high-voltage wire harness 35 between the front end position of the vehicle body longitudinal beam 32 and the rear end position of the vehicle body longitudinal beam 32 is arranged approximately along the X direction of the vehicle body. This part of the front suspension high-voltage wire harness 35 does not participate in the wheel hop and steering process, and is arranged along the vehicle body longitudinal beam 32, so it can be directly fixed. The front suspension high-voltage wire harness 35 between the rear end position of the vehicle body longitudinal beam 32 and the vehicle-mounted MCU is shorter, has a stable structure, and is not prone to shaking.

[0090] The first high-voltage wire harness fixing bracket 38 of the present embodiment is a cable tie, a buckle or other forms of structure, as long as it can satisfy the function of fixing the front suspension high-voltage wire harness 35, and has the function of fixing the front suspension high-voltage wire harness 35 to the steering knuckle 31, the front end position of the vehicle body longitudinal beam 32, and the rear end position of the vehicle body longitudinal beam 32.

[0091] The front suspension fixing bracket includes a plurality of first low-voltage harness fixing brackets 39, such as Figures 7 to 11 As shown, a plurality of first low-voltage harness fixing brackets 39 are arranged in sequence and spaced apart along the extension direction of the low-voltage harness, and are used to fix the front suspension low-voltage harness 36 to the stator housing 5 and the steering knuckle 31, shock absorber 33, and vehicle body longitudinal beam 32 in the front suspension.

[0092] like Figures 7 to 11As shown, the front suspension low-voltage wire harness 36 of this embodiment is relatively long, and a total of six first low-voltage wire harness fixing brackets 39 are provided, which are used to fix the front suspension low-voltage wire harness 36 to the stator housing 5, fix the front suspension low-voltage wire harness 36 to the steering knuckle 31 (there are two first low-voltage wire harness fixing brackets 39 on the steering knuckle 31), fix the front suspension low-voltage wire harness 36 to the shock absorber 33, fix the front suspension low-voltage wire harness 36 to the front end position of the vehicle body longitudinal beam 32, and fix the front suspension low-voltage wire harness 36 to the front end position of the vehicle body longitudinal beam 32. The wiring harness 36 is fixed at the rear end position of the vehicle body longitudinal beam 32, and the first low-voltage wiring harness fixing bracket 39 can adopt a snap-on structure, that is, a snap-on structure is reserved at the front end position of the stator housing 5, the steering knuckle 31, the shock absorber 33, the vehicle body longitudinal beam 32, and the rear end position of the vehicle body longitudinal beam 32, and then when installing the front suspension low-voltage wiring harness 36, the snap-on structure on the front suspension low-voltage wiring harness 36 is directly fixed to the corresponding snap, so that the front suspension low-voltage wiring harness 36 can be fixed.

[0093] For the front suspension low-voltage wiring harness 36, the front suspension low-voltage wiring harness 36 between the low-voltage wiring harness interface 52 on the front wheel stator housing 5 and the first low-voltage wiring harness fixing bracket 39 on the stator housing 5 is relatively short, and the fixation on the stator housing 5 is extremely stable, so no special design is required; the front suspension low-voltage wiring harness 36 between the first low-voltage wiring harness fixing bracket 39 at the front end position of the vehicle body longitudinal beam 32 and the first low-voltage wiring harness fixing bracket 39 on the shock absorber 33 is relatively long, and needs to adapt to wheel hop and steering. The first low-voltage wiring harness fixing bracket 39 before the shock absorber 33 is following The motor bounces and turns, so the front suspension low-voltage wiring harness 36 between the front end position of the vehicle body longitudinal beam 32 and the two first low-voltage wiring harness fixing brackets 39 of the shock absorber 33 is a bending structure with a telescopic margin to adapt to the wheel bounce and steering; the front suspension low-voltage wiring harness 36 between the first low-voltage wiring harness fixing bracket 39 on the shock absorber 33 and the in-vehicle communicator is fixed by multiple first low-voltage wiring harness fixing brackets 39, and this part of the front suspension low-voltage wiring harness 36 does not participate in the adaptation process of wheel bounce and steering, so it only needs to be fixed without any other arrangement.

[0094] In this embodiment, the arrangement of the front suspension high-voltage harness 35 and the front suspension low-voltage harness 36 are separated in position. The front suspension high-voltage harness 35 is directly connected to the steering knuckle 31 from the stator housing 5, and then arranged along the vehicle body longitudinal beam 32, and finally connected to the vehicle-mounted MCU. The front suspension low-voltage harness 36 is fixed on the stator housing 5 and then connected to the steering knuckle 31, and then connected to the shock absorber 33, and then arranged along the vehicle body longitudinal beam 32, and finally connected to the in-vehicle communicator. In the area adapted to wheel hop and steering, the front suspension high-voltage harness 35 and the front suspension low-voltage harness 36 are separated in the Z direction. The front suspension high-voltage harness 35 between the front end of the steering knuckle 31 and the vehicle body longitudinal beam 32 and the front suspension low-voltage harness 36 between the steering knuckle 31 and the shock absorber 33 are isolated from each other in the Z direction, and there will be no entanglement problem.

[0095] The front suspension fixing bracket of this embodiment includes a plurality of first water pipe fixing brackets 310, which are arranged in sequence and spaced apart along the extension direction of the cooling water pipe, and are used to fix the front suspension cooling water pipe 37 to the steering knuckle 31 and the front bracket 34 in the front suspension.

[0096] like Figures 12-14 As shown, there are two first water pipe fixing brackets 310 in this embodiment, which are used to fix the front suspension cooling water pipe 37 to the steering knuckle 31 and the cooling water pipe to the front bracket 34 respectively. One end of the front suspension cooling water pipe 37 is connected to the water cooling pipe interface 53 of the stator housing 5, and then fixed to the steering knuckle 31 through one first water pipe fixing bracket 310, fixed to the front bracket 34 through another first water pipe fixing bracket 310, and finally connected to the radiator of the vehicle body.

[0097] The front suspension cooling water pipe 37 between the first water pipe fixing bracket 310 on the steering knuckle 31 and the water cooling pipe interface 53 is shorter, so it can be directly fixed and installed; the front suspension cooling water pipe 37 between the first water pipe fixing bracket 310 on the steering knuckle 31 and the first water pipe fixing bracket 310 on the front bracket 34 is longer, and is approximately arranged along the Y direction of the vehicle body, and needs to participate in the wheel hop and steering. Therefore, the front suspension cooling water pipe 37 between the two first water pipe fixing brackets 310 of the steering knuckle 31 and the front bracket 34 is a bending structure with a telescopic margin to adapt to wheel hop and steering; the front suspension cooling water pipe 37 between the first water pipe fixing bracket 310 of the front bracket 34 and the radiator does not participate in wheel hop and steering, and can be directly fixed and installed.

[0098] That is, the front suspension high-voltage harness 35, the front suspension low-voltage harness 36 and the front suspension cooling water pipe 37 of this embodiment are all fixedly connected to the stator housing 5 and the steering knuckle 31. For the area where winding interference is easy to occur, the front suspension high-voltage harness 35, the front suspension low-voltage harness 36 and the front suspension cooling water pipe 37 are separated in the Z direction, and the problem of winding will not occur. Specifically, the front suspension high-voltage harness between the two first high-voltage harness fixing brackets 38 at the front end of the steering knuckle 31 and the vehicle body longitudinal beam 32, the front suspension cooling water pipe between the two first water pipe fixing brackets 310 at the steering knuckle 31 and the front bracket 34, and the front suspension low-voltage harness between the two first low-voltage harness fixing brackets 39 at the front end of the vehicle body longitudinal beam 32 and the shock absorber 33 are arranged at intervals along the Z direction.

[0099] The first water pipe fixing bracket 310 of the present embodiment can adopt a snap-on structure. By providing a snap-on structure on the steering knuckle 31 and the front bracket 34, a corresponding snap-on is installed on the front suspension cooling water pipe 37. Then, when installing the front suspension cooling water pipe 37, the snap-on on the front suspension cooling water pipe 37 is directly snapped into the snap-on structure on the steering knuckle 31 and the front bracket 34, thereby completing the fixation of the front suspension cooling water pipe 37 to the steering knuckle 31 and the front bracket 34.

[0100] In practical application, the structure is not limited to the above-mentioned first high-voltage wire harness fixing bracket 38, the first low-voltage wire harness fixing bracket 39 and the first water pipe fixing bracket 310, as long as it can meet the corresponding requirements.

[0101] In other embodiments of the present application, the present embodiment optimizes the above-mentioned rear suspension fixing bracket, specifically, Figures 16 to 26 As shown, the rear suspension fixing bracket includes a plurality of second high-voltage wire harness fixing brackets 47, which are arranged in sequence and spaced apart along the extension direction of the rear suspension high-voltage wire harness 44, and are used to fix the rear suspension high-voltage wire harness 44 to the joint head 41 and the rear bracket 43 in the rear suspension.

[0102] like Figures 16 to 19As shown, there are two second high-voltage harness fixing brackets 47 of this embodiment, which are used to fix the rear suspension high-voltage harness 44 to the joint head 41 and the rear suspension high-voltage harness 44 to the rear bracket 43, that is, there are four fixing points corresponding to the rear suspension high-voltage harness 44, namely the stator housing 5, the joint head 41, the rear bracket 43 and the vehicle-mounted MCU (the interface corresponding to the vehicle-mounted MCU at the rear of the vehicle body). The rear suspension high-voltage harness 44 between the joint head 41 and the stator housing 5 is very short, and the structure is relatively stable and not easy to shake; the rear suspension high-voltage harness 44 between the joint head 41 and the rear bracket 43 The rear suspension high-voltage wiring harness 44 between the two second high-voltage wiring harness fixing brackets 47 on the joint head 41 and the rear bracket 43 is relatively long, and this part of the rear suspension high-voltage wiring harness 44 extends approximately in the Y direction of the vehicle body, and needs to cope with wheel hop. Therefore, in this embodiment, the rear suspension high-voltage wiring harness 44 between the joint head 41 and the two second high-voltage wiring harness fixing brackets 47 on the rear bracket 43 is a bending structure with a telescopic margin to adapt to wheel hop. Leaving the telescopic margin can avoid the problem of pulling interference during wheel hop; the rear suspension high-voltage wiring harness 44 between the rear bracket 43 and the vehicle-mounted MCU is shorter, has a stable structure, and is not prone to shaking.

[0103] The second high-voltage wire harness fixing bracket 47 of this embodiment is a cable tie, a buckle or other forms of structure, as long as it can meet the function of fixing the rear suspension high-voltage wire harness 44, and has the function of fixing the rear suspension high-voltage wire harness 44 to the joint head 41 and the rear bracket 43.

[0104] The rear suspension fixing bracket of this embodiment includes multiple second low-voltage wire harness fixing brackets 48, which are arranged in sequence and spaced apart along the extension direction of the rear suspension low-voltage wire harness 45, and are used to fix the rear suspension low-voltage wire harness 45 to the joint head 41 and the rear bracket 43 in the rear suspension.

[0105] like Figures 20-24 As shown, the rear suspension low-voltage wiring harness 45 of this embodiment is longer than the rear suspension high-voltage wiring harness 44, and a total of four second low-voltage wiring harness fixing brackets 48 are provided, which are respectively used to fix the rear suspension low-voltage wiring harness 45 to the joint head 41, fix the low-voltage wiring harness to the spring arm 42 (two second low-voltage wiring harness fixing brackets 48 are provided on the spring arm 42), and fix the rear suspension low-voltage wiring harness 45 to the rear bracket 43. The second low-voltage wiring harness fixing bracket 48 can adopt a snap-on structure, that is, a snap-on structure is reserved on the joint head 41, the spring arm 42, and the rear bracket 43. Then, when installing the rear suspension low-voltage wiring harness 45, the snap-on structure on the rear suspension low-voltage wiring harness 45 is directly fixed to the corresponding snap, thereby completing the fixation of the rear suspension low-voltage wiring harness 45.

[0106] For the rear suspension low-voltage wiring harness 45, the rear suspension low-voltage wiring harness 45 between the low-voltage wiring harness interface 52 on the rear wheel stator housing 5 and the second low-voltage wiring harness fixing bracket 48 on the joint head 41 is relatively short, and the fixation on the stator housing 5 is extremely stable, so no special design is required; the rear suspension low-voltage wiring harness 45 between the second low-voltage wiring harness fixing bracket 48 on the joint head 41 and the second low-voltage wiring harness fixing bracket 48 on the spring arm 42 is relatively long and needs to adapt to wheel jump, so the rear suspension low-voltage wiring harness 45 between the two second low-voltage wiring harness fixing brackets 48 of the joint head 41 and the spring arm 42 is a bending structure with a telescopic margin to adapt to wheel jump; the rear suspension low-voltage wiring harness 45 between the second low-voltage wiring harness fixing bracket 48 on the spring arm 42 and the in-vehicle communicator has a second low-voltage wiring harness fixing bracket 48 for fixing, and this part of the rear suspension low-voltage wiring harness 45 does not participate in the adaptation process of wheel jump, so it only needs to be fixed without other arrangements.

[0107] In this embodiment, the rear suspension high-voltage wiring harness 44 and the rear suspension low-voltage wiring harness 45 are arranged in a separated position. The rear suspension high-voltage wiring harness 44 is directly connected from the stator housing 5 to the joint head 41, and then connected to the rear bracket 43; while the rear suspension low-voltage wiring harness 45 of this embodiment is led out from the stator housing 5, connected to the joint head 41, then connected to the spring arm 42, and finally connected to the rear bracket 43. The rear suspension low-voltage wiring harness 45 between the joint head 41 and the rear bracket 43 is passed through the second low-voltage wiring harness fixing bracket 48 on the spring arm 42. The connection between the rear suspension low-voltage wiring harness 45 and the rear bracket 43 and the connection between the rear suspension high-voltage wiring harness 44 and the rear bracket 43 are arranged at intervals in the X direction. Because the rear wheel of the vehicle only has wheel hop and does not involve steering, the rear suspension low-voltage wiring harness 45 and the rear suspension high-voltage wiring harness 44 can only produce relative movement along the Z direction, and there is no relative movement along the X and Y directions. By separating in the X direction, the rear suspension low-voltage wiring harness 45 and the rear suspension high-voltage wiring harness 44 between the joint head 41 and the rear bracket 43 will not have the problem of entanglement and interference.

[0108] The rear suspension fixing bracket of this embodiment includes a plurality of second water pipe fixing brackets 49, which are arranged in sequence and spaced apart along the extension direction of the rear suspension cooling water pipe 46, and are used to fix the rear suspension cooling water pipe 46 to the joint head 41 in the rear suspension.

[0109] like Fig.25 , 26 As shown, there are two second water pipe fixing brackets 49 in this embodiment, which are used to fix the rear suspension cooling water pipe 46 to the joint head 41. One end of the rear suspension cooling water pipe 46 is connected to the water cooling pipe interface 53 of the stator housing 5 of the rear suspension wheel, and then fixed to the joint head 41 through the second water pipe fixing bracket 49, and finally connected to the motor water pipe assembly of the vehicle body.

[0110] The rear suspension cooling water pipe 46 between the second water pipe fixing bracket 49 on the joint head 41 and the water cooling pipe interface 53 is shorter, so it can be directly fixed and installed; the rear suspension cooling water pipe 46 between the second water pipe fixing bracket 49 on the joint head 41 and the second water pipe fixing bracket 49 on the rear bracket 43 is longer, and is approximately arranged along the Y direction of the vehicle body, and needs to participate in the wheel hop, so the rear suspension cooling water pipe 46 between the two second water pipe fixing brackets 49 of the joint head 41 and the rear bracket 43 is a bending structure with a telescopic margin to adapt to wheel hop; the rear suspension cooling water pipe 46 between the second water pipe fixing bracket 49 of the rear bracket 43 and the motor water pipe assembly does not participate in wheel hop adaptation, and can be directly fixed and installed.

[0111] That is, the rear suspension high-voltage wiring harness 44, the rear suspension low-voltage wiring harness 45 and the rear suspension cooling water pipe 46 of this embodiment are all fixedly connected to the stator housing 5 and the joint head 41. For the area where entanglement interference is prone to occur, the rear suspension high-voltage wiring harness 44, the rear suspension low-voltage wiring harness 45 and the rear suspension cooling water pipe 46 are separated in the X direction. Specifically, the rear suspension high-voltage wiring harness between the two second high-voltage wiring harness fixing brackets 47 of the joint head 41 and the rear bracket 43, the rear suspension low-voltage wiring harness between the two second low-voltage wiring harness fixing brackets 48 of the joint head 41 and the spring arm 42, and the rear suspension cooling water pipe between the two second water pipe fixing brackets 49 of the joint head 41 and the rear bracket 43 are arranged at intervals along the X direction, so there will be no problem of mutual entanglement.

[0112] The second water pipe fixing bracket 49 of the present embodiment can adopt a snap-on structure. By providing a buckle plate structure on the joint head 41 and the rear bracket 43, a corresponding buckle is installed on the rear suspension cooling water pipe 46. Then, when installing the rear suspension cooling water pipe 46, the buckle on the rear suspension cooling water pipe 46 is directly buckled into the buckle plate structure on the joint head 41 and the rear bracket 43, thereby completing the fixation of the rear suspension cooling water pipe 46 to the joint head 41 and the rear bracket 43.

[0113] In practical application, the structures of the second high-voltage wire harness fixing bracket 47 , the second low-voltage wire harness fixing bracket 48 and the second water pipe fixing bracket 49 are not limited thereto, as long as they can meet corresponding requirements.

[0114] In other embodiments of the present application, the present embodiment optimizes the above-mentioned wheel rim 1 and wheel hub motor structure. Specifically, Figures 28-30 As shown, the rim 1 of this embodiment is a hollow spokeless annular structure. Since the rim 1 is a spokeless annular structure, the weight of the rim 1 is extremely small, which greatly reduces the weight of the wheel assembly. At the same time, the spokeless rim 1 structure has a larger internal space, which is more convenient for the installation and arrangement of the hub motor.

[0115] The wheel hub motor of this embodiment includes an outer rotor housing 2. The wheel hub motor wheel edge integrated structure of this embodiment mainly illustrates the connection structure between the wheel hub motor and the wheel rim 1. The wheel hub motor includes an outer rotor housing 2 and a stator housing 5. The outer rotor housing 2 is fixedly connected to the wheel rim 1 and rotates with the wheel. The stator housing 5 is non-rotating and fixedly connected to the vehicle body suspension. The outer rotor housing 2 is sleeved inside the wheel rim 1, that is, the internal space of the wheel rim 1 is fully utilized for the installation of the outer rotor housing 2. The end of the outer rotor housing 2 away from the vehicle body is fixedly connected to the wheel rim 1, and the end of the outer rotor housing 2 close to the vehicle body is rotatably connected to the stator housing 5 around the axis.

[0116] In this embodiment, a first connection structure is provided at the end of the rim 1 away from the vehicle body, and a second connection structure is provided at the end of the outer rotor housing 2 away from the vehicle body. The first connection structure and the second connection correspond to each other, and the outer rotor housing 2 and the rim 1 are fixedly connected as a whole through the first connection structure and the second connection structure.

[0117] The outer rotor housing 2 is fixed in the rim 1 through the first connection structure and the second connection structure, so that the outer rotor housing 2 is flush with the end of the rim 1 away from the vehicle body.

[0118] In this embodiment, the outer rotor housing 2 of the hub motor is inserted axially into the rim 1 so that the first connection structure and the second connection structure are aligned; connecting bolts are driven into the first connection structure and the second connection structure to fix the outer rotor housing 2 and the rim 1 as a whole.

[0119] This embodiment also optimizes the first connection structure and the second connection structure. Specifically, Figures 29-30 As shown, the first connection structure is located on the inner side of the circumference of the rim 1 away from the vehicle body, and the second connection structure is located on the outer side of the circumference of the outer rotor housing 2 away from the vehicle body. The first connection structure and the second connection structure are connected as a whole in the axial direction.

[0120] In order to maximize the use of the internal space of the rim 1, the first connection structure is designed in this embodiment at the inner side of the circumference of the rim 1 away from the vehicle body. Therefore, the connection between the rim 1 and the outer rotor housing 2 is at the inner side of the circumference of the rim 1 away from the vehicle body. This connection arrangement minimizes the occupation of the internal space of the rim 1 by the connection structure of the rim 1 and the outer rotor housing 2. At the same time, the arrangement of the connection structure at a position close to the inner side of the end circumference greatly facilitates the assembly of the two components.

[0121] During actual assembly, the end of the outer rotor housing 2 provided with the second connection structure is inserted into the rim 1 along the axial direction of the outer rotor housing 2 from the end of the rim 1 close to the vehicle body, so that the second connection structure fits together with the first connection structure in the axial direction.

[0122] The outer rotor housing 2 is a cylindrical structure. During assembly, one end provided with the second connection structure is inserted into the rim 1 axially from the end of the rim 1 close to the vehicle body, so that the second connection structure fits together with the first connection structure in the axial direction.

[0123] Furthermore, this embodiment defines the relative positions of the first connecting structure and the second connecting structure during assembly, such as Fig. 27 , 29 As shown in FIG. 30 , the first connection structure is located at a side of the second connection structure away from the vehicle body.

[0124] Therefore, when the end of the outer rotor housing 2 provided with the second connection structure is inserted into the rim 1 along the axial direction from the end of the rim 1 close to the vehicle body, the end of the outer rotor housing 2 away from the vehicle body does not extend beyond the rim 1, and the second connection structure on the outer rotor housing 2 is located on the side of the first connection structure of the rim 1 close to the vehicle body. The outer rotor housing 2 makes maximum use of the internal space of the rim 1 without being exposed to affect its use.

[0125] This embodiment also optimizes the specific structures of the first connection structure and the second connection structure. Figures 27-30 As shown, the first connection structure of this embodiment includes a flange 11, which is an annular structure located at the end of the rim 1 away from the vehicle body. The outer circumferential side of the flange 11 is connected to the rim 1, and a plurality of first screw holes 12 arranged at equal intervals along the circumferential direction are provided on the flange 11. The second connection structure includes a plurality of lugs 21 arranged at the outer circumferential side of the end of the outer rotor housing 2 away from the vehicle body. The plurality of lugs 21 are arranged at equal intervals along the circumferential direction on the outer rotor housing 2. The lugs 21 are plate-shaped structures extending in the radial direction. The lugs 21 are provided with second screw holes 22. The lugs 21 are fixedly connected to the flange 11 by bolts axially penetrated through the first screw holes 12 and the second screw holes 22.

[0126] The flange 11 and the ear plate 21 are corresponding structures, and the side of the flange 11 facing the vehicle body is tightly fitted with the side of the ear plate 21 facing away from the vehicle body. The first screw holes 12 arranged equidistantly along the circumferential direction on the flange 11 and the second screw holes 22 on the ear plate 21 correspond to each other one by one, and are fixedly connected as a whole by bolts penetrating the first screw holes 12 and the second screw holes 22.

[0127] During actual assembly, one end of the outer rotor housing 2 provided with the ear plate 21 is inserted into the rim 1 along the axial direction of the outer rotor housing 2 from the end of the rim 1 close to the vehicle body, so that the ear plate 21 and the flange 11 are fitted together in the axial direction, and the ear plate 21 is located on the side of the flange 11 facing the vehicle body; the outer rotor housing 2 and the rim 1 are rotated around the axial direction, so that the first screw hole 12 on the flange 11 and the second screw hole 22 on the ear plate 21 are aligned in the axial direction; bolts are driven into the aligned first screw hole 12 and second screw hole 22 from the side of the rim 1 away from the vehicle body, and the order of driving the bolts is to drive them symmetrically with the axis of the rim 1 as the center, until all the bolts are driven in, and the connection between the rim 1 and the outer rotor housing 2 is completed.

[0128] Furthermore, in this embodiment, a riveted nut is installed at the end of the bolt on one side of the flange 11. The riveted nut can protect the exposed end of the bolt on one hand, and can enhance the tightness of the connection between the bolt and the rim 1 and the outer rotor housing 2 on the other hand, ensuring that the bolt is tightly fixed in the first screw hole 12 and the second screw hole 22.

[0129] During the actual assembly of the present application: insert one end of the outer rotor housing 2 provided with the ear plate 21 into the rim 1 along the axial direction of the outer rotor housing 2 from the end of the rim 1 close to the vehicle body, so that the ear plate 21 and the flange 11 are fitted together in the axial direction, and the ear plate 21 is located on the side of the flange 11 facing the vehicle body; rotate the outer rotor housing 2 and the rim 1 around the axial direction, so that the first screw hole 12 on the flange 11 and the second screw hole 22 on the ear plate 21 are aligned in the axial direction; drive bolts into the aligned first screw hole 12 and second screw hole 22 from the side of the rim 1 away from the vehicle body, and the order of driving the bolts is to drive them symmetrically with the axis of the rim 1 as the center, until all the bolts are driven in, and the fixed connection between the rim 1 and the outer rotor housing 2 is completed;

[0130] Install the stator housing 5 and the suspension, respectively fix the stator housing 5 of the front wheel and the front suspension, and fix the stator housing 5 of the rear wheel and the rear suspension;

[0131] Assemble the front suspension harness and water pipes, connect one end of the front suspension high-voltage harness 35 to the high-voltage harness interface 51 of the stator housing 5 of the front wheel, and use a plurality of first high-voltage harness fixing brackets 38 to fix the front suspension high-voltage harness 35 in turn at the steering knuckle 31, the front end of the vehicle body longitudinal beam 32, and the rear end of the vehicle body longitudinal beam 32. Finally, insert the end of the front suspension high-voltage harness 35 into the vehicle-mounted MCU. When fixing the front suspension high-voltage harness 35 with the first high-voltage harness fixing bracket 38, arrange the front suspension high-voltage harness 35 between the two first high-voltage harness fixing brackets 38 of the steering knuckle 31 and the vehicle body longitudinal beam 32 into a bending structure with a telescopic margin to accommodate wheel bouncing and steering.

[0132] Connect one end of the front suspension low-voltage wire harness 36 to the low-voltage wire harness interface 52 of the stator housing 5 of the front wheel, and use a plurality of first low-voltage wire harness fixing brackets 39 to fix the front suspension low-voltage wire harness 36 to the stator housing 5, the steering knuckle 31, the shock absorber 33, the front end of the vehicle body longitudinal beam 32, and the rear end of the vehicle body longitudinal beam 32 in sequence, and finally insert the end of the front suspension low-voltage wire harness 36 into the vehicle-mounted communicator. When the front suspension low-voltage wire harness 36 is fixed by the first low-voltage wire harness fixing bracket 39, the front suspension low-voltage wire harness 36 between the front end of the vehicle body longitudinal beam 32 and the two first low-voltage wire harness fixing brackets 39 of the shock absorber 33 is arranged into a bending structure with a telescopic margin to adapt to wheel bounce and steering;
