DETAILED DESCRIPTION

[0033] 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.

[0034] In the present disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts in the direction of gravity when the corresponding parts are in use, and "inner" and "outer" refer to the inner and outer parts relative to the outline of the parts or structures themselves. In addition, it should be noted that the terms used, such as "first" and "second", 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.

[0035] like Figure 2 As shown, the present disclosure provides a steering knuckle of a vehicle, comprising: a steering knuckle body 2 for connecting to a wheel hub motor 1 , a wire through hole 21 being provided on the steering knuckle body 2 for a first wire harness 4 connected to the wheel hub motor 1 to pass through.

[0036] Through the above technical scheme, in the steering knuckle of the vehicle provided by the present invention, the steering knuckle body 2 is installed on the side of the hub motor 1, and a wire through hole 21 is provided on the steering knuckle body 2 for the first wiring harness 4 extending from the side of the hub motor 1 to pass through, so that the space occupied by the first wiring harness 4 and the steering knuckle body 2 overlap, avoiding the first wiring harness 4 and the steering knuckle body 2 from occupying too much space on the side of the hub motor 1, and providing sufficient space for the arrangement and installation of other components.

[0037] As an optional embodiment, one end of the steering knuckle body 2 is a mounting end 22, which is used to connect to the hub motor 1, and the mounting end 22 is in contact with the side of the hub motor 1. A wire through hole 21 is opened at the mounting end 22, and the wire through hole 21 is arranged on the part where the steering knuckle body 2 is connected to the hub motor 1, so as to make full use of the space of the steering knuckle body 2, reduce the space occupied by the first wiring harness 4 on the side of the hub motor 1, and provide sufficient space for the arrangement and installation of other components.

[0038] Optionally, a bolt hole 24 for connecting to the hub motor 1 is provided on the mounting end 22, and an axial hole 23 is provided on the mounting end 22. The aperture of the wire through hole 21 is smaller than the aperture of the axial hole 23. The axial hole 23 is used to connect the main shaft. For example, the bolt hole 24 is arranged on the inner side of the axial hole 23, which reduces the space occupied on the side of the hub motor 1 compared to being arranged on the outer side of the axial hole 23. The aperture of the wire through hole 21 is smaller than the aperture of the axial hole 23. Because the diameter of the first wiring harness 4 must be smaller than the diameter of the main shaft, a too large wire through hole 21 will increase the occupied space.

[0039] Among them, the wire through hole 21 and the shaft hole 23 are arranged adjacent to each other and a partition 25 is provided between the wire through hole 21 and the shaft hole 23. On the one hand, the partition 25 can prevent the shaft hole 23 from being connected with the wire through hole 21 to cause a larger hole diameter and reduce the strength of the steering knuckle body 2. On the other hand, the partition 25 isolates the first wire harness 4 from the main shaft to prevent the first wire harness 4 from contacting the main shaft and causing wear.

[0040] like Figure 1-5 As shown, the second object of the present disclosure is to provide a wheel edge angle module, comprising: a hub motor 1, which is used to be arranged in a wheel hub, the hub motor 1 comprises a stator bracket 3, and a first wiring hole 7 is opened on the stator bracket 3; and the steering knuckle of the above-mentioned vehicle, the projection of the wire through hole 21 in the axial direction of the hub motor 1 at least partially overlaps with the first wiring hole 7.

[0041] For example, the stator bracket 3 is fixedly arranged on one side of the hub motor 1 and is arranged perpendicular to the driving shaft of the hub motor 1. The steering knuckle body 2 is arranged on the side of the stator bracket 3 away from the hub motor 1. The stator bracket 3 is provided with a first wiring hole 7, so that the first wiring harness 4 is arranged and 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 is provided with a wire through hole 21. The projection of the wire through hole 21 in the axial direction of the hub motor 1 at least partially overlaps with the first wiring hole 7, so that the first wire harness 4 can pass through the wire through hole 21, thereby avoiding the first wire harness 4 and the steering knuckle body 2 from occupying too much space on the side of the stator bracket 3, and providing sufficient space for the arrangement and installation of other components.

[0042] As an optional implementation, Figure 1 As shown, the projection of the wire through hole 21 in the axial direction of the hub motor 1 completely covers the first wiring hole 7, and the area of ​​the wire through hole 21 is larger than the area of ​​the first wiring hole 7, which facilitates the first wiring harness 4 to pass through the wire through hole 21 and the first wiring hole 7, and also facilitates the installation and removal of the first wiring harness 4 and the connector used to connect the first wiring harness 4.

[0043] As an optional implementation, Figure 3 As shown, the first wiring hole 7 is arranged on the radial center line of the hub motor 1, for example, on the longitudinal radial center line of the hub motor 1, so as to solve the problem of pipeline arrangement of the hub motor 1 and symmetrical arrangement of the left and right wheels, so that the hub motors 1 in four directions of the vehicle can use the same hub motor 1, thereby eliminating the need for two hub motors 1 to cope with the installation of the left and right wheels, reducing the types of motor parts and components, and facilitating production and material management in the workshop.

[0044] Alternatively, if Figure 1 and Figure 4 As shown, the wheel angle module also includes a first connector 6, which is connected to the first wiring hole 7. A through hole is formed on the first connector 6 for the first wiring harness 4 to pass through. The first wiring harness 4 passes through the through hole and is connected to the first connector 6. For example, the first wiring harness 4 is constructed as a high-voltage line, which is the power line of the hub motor 1. For example, the first wiring hole 7 is set on the radial center line in the longitudinal direction of the hub motor 1 to match the arrangement and installation of the steering knuckle body 2, and being set on the radial center line in the longitudinal direction will not involve the problem of different angles and directions of the left and right wheels. Of course, in other embodiments, the first wiring hole 7 can also be set on the radial center line in the transverse direction of the hub motor 1.

[0045] Optionally, the projection of the through hole in the axial direction of the hub motor 1 coincides with the first wiring hole 7 , ensuring that the first wiring harness 4 can pass through the first wiring hole 7 through the through hole.

[0046] As an optional implementation, Figure 1 and Figure 3-4 As shown, the stator bracket 3 is further provided with a connection hole 5, and the connection hole 5 is used for allowing at least one of the second wire harness 10 and the cooling pipe to pass through, and the connection hole 5 is used to connect the second wire harness 10 and the cooling pipe.

[0047] Optionally, there are multiple connecting holes 5, and the multiple connecting holes 5 are symmetrically arranged on both sides of the steering knuckle body 2, which is also to solve the problem of pipeline arrangement of the motor and symmetrical arrangement of the left and right wheels.

[0048] Optionally, the connecting hole 5 includes a water inlet hole 52 and a water outlet hole 53 for connecting the cooling pipe. For example, the water inlet hole 52 and the water outlet hole 53 are symmetrically arranged along the radial center line of the hub motor 1, and the radial center line is the longitudinal radial center line. The size and structure of the water inlet hole 52 and the water outlet hole 53 are exactly the same. The cooling pipe can be used as both a water inlet pipe and a water outlet pipe, so there is no problem of different positions of the water inlet holes 52 and the water outlet holes 53 of the left and right wheels.

[0049] Optionally, the connecting hole 5 also includes a second wiring hole 51 for connecting the second wiring harness 10, and the wheel corner module also includes a second connector 9. The second wiring harness 10 is connected to the second wiring hole 51 through the second connector 9. For example, the second wiring harness 10 is a low-voltage line, and the second wiring hole 51 is symmetrically provided with two along the radial center line of the hub motor 1. For example, the radial center line is a longitudinal radial center line. The second wiring harness 10 can be selectively connected to one of the second wiring holes 51. The second wiring harness 10 is the signal line of the hub motor 1. The second wiring hole 51 is provided with two and the radial center line of the hub motor 1 is set. The second wiring harness 10 is provided with a group and passes through one of the second wiring holes 51. The other second wiring hole 51 is reserved for the symmetrical wheel to solve the problems of pipeline layout of the motor and symmetrical layout of the left and right wheels.

[0050] Among them, the diameter of the second wiring harness 10 is smaller than the diameter of the first wiring harness 4. Because the diameter of the first wiring harness 4 is larger than the diameter of the second wiring harness 10, that is, the diameter of the high-voltage line is larger than the diameter of the low-voltage line, the first wiring harness 4 occupies a larger space, so the first wiring hole 7 for connecting the first wiring harness 4 is set in the center and passes through the wire through hole 21 to reduce the occupied space on the side of the stator bracket 3. There must be two water inlet holes 52 and two water outlet holes 53, so they can only be set symmetrically along the radial center line.

[0051] Alternatively, if Figure 1 and Figure 3-5As shown, a mounting hole 8 is provided at the center of the stator bracket 3, one end of the steering knuckle body 2 is mounted at the mounting hole 8, and the other end extends upward, the first wiring hole 7 and the connecting hole 5 are both arranged above the mounting hole 8, the first wiring harness 4, the second wiring harness 10 and the cooling pipe are all extended in the same direction as the steering knuckle body 2, and the first wiring harness 4, the second wiring harness 10 and the cooling pipe are all fixed on the steering knuckle body 2 by a fixing device to move synchronously with the steering knuckle body 2, 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 the space requirement, the steering knuckle body 2 extends upward, the first wiring hole 7 and the connecting hole 5 are arranged above the mounting hole 8, so that the pipeline can occupy a smaller space when fixed to the steering knuckle; at the same time, because other components are installed below the stator bracket 3, the pipeline can be led out from the top to better utilize the space.

[0052] The third object of the present disclosure is to provide a vehicle, comprising: the above-mentioned wheel corner module. The wheel corner module in the present disclosure, the first wiring harness 4 is arranged and installed on the side of the hub motor 1, and will not occupy the radial dimension space of the hub motor 1. The first wiring harness 4 can pass through the wire through hole 21 to avoid the first wiring harness 4 and the steering knuckle body 2 occupying too much space on the side of the stator bracket 3, providing sufficient space for the arrangement and installation of other components.

[0053] 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.

[0054] 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.

[0055] 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.
