[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] In the present disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower positions of the corresponding parts in the direction of gravity when in use, and "inner" and "outer" refer to the inner and outer positions relative to the contour of the parts or structures themselves. In addition, it should be noted that the terms used, such as "first, second, third", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0030] like Figure 1 and Figure 4 As shown, the present disclosure provides a steering knuckle for a vehicle, comprising: a steering knuckle body 2, which is used to connect with a wheel hub motor 1, the steering knuckle body 2 comprises a first section 21 and a second section 22, one end of the first section 21 is used to connect with the wheel hub motor 1, and the other end extends in a direction away from the wheel hub motor 1 and is connected to the second section 22, so that an avoidance space 7 is formed on the steering knuckle body 2.

[0031] Through the above technical scheme, in the steering knuckle for a vehicle provided by the present invention, the steering knuckle body 2 is installed on the wheel hub motor 1, the first section 21 of the steering knuckle body 2 is connected to the wheel hub motor 1, the first section 21 extends a distance to the side away from the wheel hub motor 1 and is connected to the second section 22 to form an avoidance space 7 between the first section 21 and the second section 22, so that the wheel hub motor 1 has a larger installation space, so as to provide sufficient space for the arrangement and installation of other components.

[0032] In some embodiments, the second section 22 extends upward from the other end of the first section 21 .

[0033] As an optional embodiment, there can be multiple angles between the first section 21 and the second section 22. For example, in the present disclosure, the first section 21 and the second section 22 are vertically arranged and the first section 21 is used to be vertically arranged with the side of the hub motor 1, so that the second section 22 can extend in a direction parallel to the stator bracket 3, and the distance between each part of the second section 22 and the hub motor 1 is equal, which is convenient for installing parts.

[0034] As an optional embodiment, a mounting seat 8 is provided on the first section 21, and the mounting seat 8 is used to connect to the hub motor 1. The mounting seat 8 is provided with bolt holes. For example, the mounting seat 8 is arranged perpendicular to the first section 21 and is arranged outside the avoidance space 7, that is, it extends in a direction away from the second section 22 and to the side, so as to avoid occupying the space in the avoidance space 7.

[0035] Optionally, the distance between the second section 22 and the side of the hub motor 1 is B, and B is the sum of the length of the first section 21 and the thickness of the mounting seat 8, so as to ensure that the avoidance space 7 has a sufficient size for installing components.

[0036] As an optional embodiment, the steering knuckle body 2 also includes a third section 23 for connecting to the steering rod. The third section 23 is connected to the end of the second section 22 away from the first section 21 and extends toward the avoidance space 7. The third section 23 extends toward the avoidance space 7 to make full use of the distance between the second section 22 and the hub motor 1 and avoid the third section 23 occupying other space.

[0037] like Figure 1-4 As shown, the second purpose of the present disclosure is to provide a wheel corner module, including: a hub motor 1, and the above-mentioned steering knuckle for a vehicle, one end of the first section 21 is connected to the hub motor 1, and the other end extends to the side away from the hub motor 1 and is connected to the second section 22 to form an avoidance space 7.

[0038] In one embodiment, the hub motor 1 includes a stator bracket 3, which is provided with a connection hole 31 for allowing the wiring harness to pass through; one end of the first section 21 is connected to the stator bracket 3, and the stator bracket 3 is spaced apart from the second section 22, and the avoidance space 7 is located on the side of the stator bracket 3 facing the steering knuckle body 2.

[0039] For example, the stator bracket 3 is arranged on one side of the hub motor 1, and a connecting hole 31 is opened on the stator bracket 3, so that the pipeline layout is installed on the side of the hub motor 1, and will not occupy the radial dimension space of the hub motor 1. The steering knuckle body 2 is installed on the stator bracket 3, and the steering knuckle body 2 includes a first section 21 and a second section 22. One end of the first section 21 is connected to the stator bracket 3, and the other end extends to the side away from the stator bracket 3 and is connected to the second section 22, so that there is a spacing between the second section 22 and the stator bracket 3, thereby reducing the space occupied by the side of the stator bracket 3 and providing sufficient space for the layout and installation of other components.

[0040] The connecting hole 31 is arranged corresponding to the avoidance space 7. For example, one end of the first section 21 is connected to the center of the stator bracket 3, and the avoidance space 7 is located on one side of the center of the stator bracket 3, that is, the steering knuckle body 2 is connected to the center of the stator bracket 3. Since the second section 22 extends upward, the connecting hole is arranged above the first section 21. The avoidance space 7 provides space for the pipeline connected to the connecting hole 31, so that when other parts of the stator bracket 3 are installed, the pipeline can be led out from the side of the hub motor 1 to reduce the radial dimension space occupied by the hub motor 1. In addition, the steering knuckle body 2 extends upward to be connected to the steering rod and the frame. The connecting hole 31 is arranged above the center of the stator bracket 3, so that the pipeline can occupy less space when fixed to the steering knuckle body 2; at the same time, because other parts are installed below the stator bracket 3, the pipeline led out from the top can also make better use of the space.

[0041] As an optional implementation, Figure 1-3 As shown, a pipeline is connected to the connection hole 31, the pipeline extends in the same direction as the steering knuckle body 2 and is fixed to the steering knuckle body 2 by a fixing device 6 so as to move synchronously with the steering knuckle body 2. For example, the fixing device 6 can be a clamp, a buckle, etc. The pipeline is led out to the frame along the steering knuckle body 2, and swings and turns with the steering knuckle body 2 during steering, thereby reducing the relative movement distance of the pipeline, reducing the risk of interference between the pipeline and other components and reducing the space requirement.

[0042] Optionally, the pipeline may include a low-voltage wire harness, a cooling water pipe, a high-voltage wire harness, etc. For example, the present disclosure takes a high-voltage wire harness as an example because the high-voltage wire harness is thicker and more representative. The pipeline includes a wire harness 5, for example, the wire harness 5 is a high-voltage wire harness. The wheel corner module also includes a connector 4, and the connecting hole 31 includes a connector mounting hole. The connector 4 is connected to the connector mounting hole. A through hole is formed on the connector 4 for the wire harness 5 to pass through. The wire harness 5 is connected to the connector 4 and passes through the through hole. The high-voltage wire harness is the power cord of the hub motor 1, and the wire harness 5 is connected to the connecting hole 31 through the connector 4.

[0043] Optionally, the projection of the through hole in the axial direction of the hub motor 1 coincides with the connector mounting hole, ensuring that the wiring harness 5 can pass through the connector mounting hole through the through hole.

[0044] Among them, Figure 3 As shown, the spacing between the second section 22 and the stator bracket 3 is B, the connector 4 protrudes from the stator bracket 3 and the protruding distance is H, the wiring harness 5 is bent along the steering knuckle body 2 and the bending radius is R, and (BH) ≥ R, that is, it is necessary to reserve enough bending space for the wiring harness 5, so that the wiring harness 5 will not bend into a dead angle when it is bent and led upward, so that the wiring harness 5 has a certain curvature, avoiding skin damage and breakage, and improving the reliability of the motor.

[0045] In addition, the diameter of a single wire harness 5 is D, for example, D=13.5 mm-15 mm, and R≥5D, that is, the bending radius of the wire harness 5 is much larger than the diameter of the single wire harness 5, and sufficient space is reserved for the bending of the wire harness 5.

[0046] The third object of the present disclosure is to provide a vehicle, comprising: the above-mentioned wheel edge angle module. The wheel edge angle module in the present disclosure has a spacing between the second section 22 of the steering knuckle body 2 and the hub motor 1, so that the hub motor 1 has a larger installation space, providing sufficient space for the arrangement and installation of other components.

[0047] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0049] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
