Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figure 1 The present invention describes a corner module device 10 and a vehicle having the same according to an embodiment of the present invention.

[0021] like Figure 1 As shown, the corner module device 10 according to an embodiment of the present utility model includes: wheel assembly 1, steering knuckle 2, fixing member 3, and steering drive 4.

[0022] In this embodiment, the steering knuckle 2 is located on the wheel assembly 1. As part of some embodiments of this application, the steering knuckle 2 can be fixedly connected to the wheel assembly 1, and the steering knuckle 2 can be fixed to the hub motor of the wheel assembly 1. For example, the steering knuckle 2 can be bolted to the hub motor of the wheel assembly 1. The steering knuckle 2 is rotatably connected to the fixing member 3, and the steering knuckle 2 can rotate relative to the shaft of the steering drive 4. Furthermore, the steering knuckle 2 can rotate relative to the fixing member 3.

[0023] The steering drive 4 is mounted on the fixing member 3. In some embodiments of this application, the steering drive 4 can be screwed, welded, snapped, etc., to the fixing member 3. The steering drive 4 is connected to the steering knuckle 2 in a transmission manner. In some embodiments of this application, the steering drive 4 can include a drive mechanism, which can be configured as a drive motor. The steering drive 4 is used to drive the steering knuckle 2 to rotate relative to the fixing member 3. The steering drive 4 can output power through the output axis of the steering knuckle 2 to drive the steering knuckle 2 to rotate relative to the fixing member 3 around the rotation axis of the steering drive 4, thereby driving the wheel assembly 1 to move, so as to achieve the effect of driving the wheel assembly 1 to turn.

[0024] Furthermore, the steering knuckle 2 is provided with a receiving space 5, and at least a portion of the steering actuator 4 is received within the receiving space 5. This arrangement allows the steering knuckle 2 and the steering actuator 4 to be arranged closely, thereby reducing the overall space occupied by the steering knuckle 2 and the steering actuator 4. Alternatively, the fixing member 3 is provided with a receiving space 5, and at least a portion of the steering actuator 4 is received within the receiving space 5. This arrangement allows the steering actuator 4 and the fixing member 3 to be arranged closely, thereby reducing the overall space occupied by the steering actuator 4 and the fixing member 3. Alternatively, the steering knuckle 2 and the fixing member 3 jointly define the receiving space 5, and at least a portion of the steering actuator 4 is received within the receiving space 5. This arrangement allows the steering knuckle 2, the fixing member 3, and the steering actuator 4 to be arranged closely, thereby reducing the overall space occupied by the steering knuckle 2, the fixing member 3, and the steering actuator 4. This makes the component layout of the corner module device 10 compact, reduces the Z-axis (vehicle height direction) dimension, and allows the corner module device 10 to occupy less space in the vehicle height direction, thereby improving the space utilization of the corner module device 10. This makes the corner module device 10 suitable for various vehicle models, especially low-roof models, which helps to expand the applicability of the corner module device 10.

[0025] In the above embodiments, by housing at least a portion of the steering drive 4 within the housing space 5, the component layout of the corner module device 10 is made compact, so that the corner module device 10 occupies less space in the height direction of the vehicle, thereby improving the space utilization of the corner module device 10, providing more space for arranging other components of the vehicle, and also helping to increase the number of vehicle models that the corner module device 10 can adapt to, thus improving the adaptability range of the corner module device 10.

[0026] In some embodiments of this application, such as Figure 1 As shown, the steering knuckle 2 includes: a rotating body 21, a first connecting part 22, and a second connecting part 23. The rotating body 21 is disposed on the wheel assembly 1. As some embodiments of this application, the rotating body 21 can be fixed to the hub motor of the wheel assembly 1. The rotating body 21 can be welded, screwed, etc., to the hub motor. Along the rotation axis direction of the steering knuckle 2, the first connecting part 22 and the second connecting part 23 are respectively disposed at both ends of the rotating body 21. As some embodiments of this application, the rotating body 21, the first connecting part 22, and the second connecting part 23 can be integrally formed, which provides better overall integrity.

[0027] At least one of the first connecting portion 22 and the second connecting portion 23 can be rotatably connected to the fixing member 3. The steering drive 4 is located between the first connecting portion 22 and the second connecting portion 23. The steering drive 4 can drive the steering knuckle 2 to rotate around the axis of the steering knuckle 2 by driving the first connecting portion 22 or the second connecting portion 23 to steer the wheel assembly 1. Along the axis of rotation of the steering knuckle 2, the lower component of the first connecting portion 22 and the second connecting portion 23 can provide support for the steering drive 4 to improve structural stability and robustness. Furthermore, this arrangement allows the steering drive 4 and the steering knuckle 2 to be compactly arranged to reduce the Z-axis dimension and improve the space utilization of the corner module device 10. In addition, the design of this application can reduce unsprung mass, which is beneficial to improving vehicle handling performance and comfort.

[0028] In some embodiments of this application, such as Figure 1 As shown, the fixing member 3 includes: a fixing body 31, a third connecting part 32, and a fourth connecting part 33. Along the rotation axis direction of the steering knuckle 2, the third connecting part 32 and the fourth connecting part 33 are respectively disposed at both ends of the fixing body 31. As some embodiments of this application, the fixing body 31, the third connecting part 32, and the fourth connecting part 33 can be integrally formed, which results in better overall integrity.

[0029] The steering drive 4 is located between the third connecting part 32 and the fourth connecting part 33. This arrangement allows the steering drive 4 and the fixing member 3 to be arranged compactly, thereby reducing the Z-axis dimension and improving the space utilization of the corner module device 10. Furthermore, along the rotation axis direction of the steering knuckle 2, the lower component of the third connecting part 32 and the fourth connecting part 33 can provide support for the steering drive 4, thereby improving structural stability and robustness.

[0030] In some embodiments of this application, such as Figure 1As shown, the rotating body 21 and the fixed body 31 are spaced apart along the direction intersecting the axis of rotation of the steering knuckle 2, so that the rotating body 21 can rotate relative to the fixed body 31, thereby reducing the risk of interference between the rotating body 21 and the fixed body 31 when they rotate relative to each other, thus improving the smoothness and safety of the operation of the corner module device 10. In addition, the rotating body 21 can have a large rotation range, which is beneficial to realize large-angle steering of the wheel assembly 1 (for example, a large 90° steering angle can be realized).

[0031] Furthermore, at least a portion of the rotating body 21 protrudes in a direction away from the fixed body 31, and / or at least a portion of the fixed body 31 protrudes in a direction away from the rotating body 21. That is, at least a portion of the rotating body 21 can protrude in a direction away from the fixed body 31 to expand the receiving space 5. At least a portion of the steering drive 4 can be received within the receiving space 5, and at least a portion of the steering drive 4 can be located between the rotating body 21 and the fixed body 31. As some embodiments of this application, the steering knuckle 2 can be constructed in a C-shape to form or together with the fixing member 3 form the receiving space 5.

[0032] Alternatively, at least a portion of the fixed body 31 may protrude in a direction away from the rotating body 21 to expand the receiving space 5, and at least a portion of the steering drive 4 may be received within the receiving space 5, with at least a portion of the steering drive 4 located between the rotating body 21 and the fixed body 31. As some embodiments of this application, the fixing member 3 may be constructed in a C-shape to form or together with the steering knuckle 2 to form the receiving space 5.

[0033] Alternatively, at least a portion of the rotating body 21 protrudes in a direction away from the fixed body 31, and at least a portion of the fixed body 31 also protrudes in a direction away from the rotating body 21, thereby expanding the receiving space 5. At least a portion of the steering drive 4 can be received within the receiving space 5, and at least a portion of the steering drive 4 can be located between the rotating body 21 and the fixed body 31. As some embodiments of this application, the steering knuckle 2 and the fixing member 3 can both be constructed in a C-shape, and the steering knuckle 2 and the fixing member 3 together form the receiving space 5. This arrangement allows the steering drive 4, steering knuckle 2, and fixing member 3 to be arranged compactly, thereby reducing the space occupied and improving the space utilization of the corner module device 10.

[0034] The corner module device 10 proposed in this application is beneficial to reducing the space occupied in the X direction (the length direction of the vehicle) and the Y direction (the width direction of the vehicle), and is beneficial to realizing large-angle steering of the wheel assembly 1 (for example, it can realize a large 90° steering angle).

[0035] In some embodiments of this application, such as Figure 1As shown, along the rotation axis direction of the steering knuckle 2, the steering drive 4 can have an upper side and a lower side. The first connecting part 22 and the third connecting part 32 can be located on the same side (upper or lower side) of the steering drive 4. The first connecting part 22 and the third connecting part 32 can be stacked and rotatably engaged. As some embodiments of this application, the first connecting part 22 and the third connecting part 32 can be pivotally connected by a connector, such as a ball pin, bearing bolt, etc., so that the first connecting part 22 can rotate relative to the third connecting part 32 around the rotation axis direction of the steering knuckle 2. This arrangement is reasonable, which is beneficial to improving the smoothness of the rotation of the steering knuckle 2, and can make the first connecting part 22, the third connecting part 32, and the steering drive 4 arranged compactly to improve space utilization.

[0036] In some embodiments of this application, such as Figure 1 As shown, along the rotation axis direction of the steering knuckle 2, the steering drive 4 can have an upper side and a lower side. The second connecting part 23 and the fourth connecting part 33 can be located on the same side (upper or lower side) of the steering drive 4. The second connecting part 23 and the fourth connecting part 33 can be stacked and rotatably engaged. As some embodiments of this application, the second connecting part 23 and the fourth connecting part 33 can be pivotally connected by a connector, such as a ball pin, bearing bolt, etc., so that the second connecting part 23 can rotate relative to the fourth connecting part 33 about the rotation axis direction of the steering knuckle 2. This arrangement is reasonable, which is beneficial to improving the smoothness of the rotation of the steering knuckle 2, and can make the second connecting part 23, the fourth connecting part 33, and the steering drive 4 arranged compactly to improve space utilization.

[0037] As some embodiments of this application, along the rotation axis direction of the steering knuckle 2, the steering drive 4 may have an upper side and a lower side, the second connecting part 23 and the fourth connecting part 33 may be located on the same side (upper side or lower side) of the steering drive 4, the second connecting part 23 and the fourth connecting part 33 may be spaced apart along the direction intersecting the rotation axis direction of the steering knuckle 2, the steering drive 4 may be drively connected to the second connecting part 23, and the steering drive 4 may be fixedly connected to the fourth connecting part 33.

[0038] In some embodiments of this application, such as Figure 1As shown, the steering drive 4 may further include a drive component and an output shaft. The drive component can be the drive mechanism described in the above embodiment, and can be configured as a drive motor. The drive component can be drivenly connected to the output shaft, and the output shaft can be drivenly connected to the second connecting part 23. The drive component outputs power and transmits the power sequentially to the output shaft and the second connecting part 23 to drive the second connecting part 23 to rotate around the pivot of the steering knuckle 2, thereby driving the steering knuckle 2 to rotate and thus driving the wheel assembly 1 to steer. By setting the drive component and the output shaft, the effect of driving the wheels to steer can be achieved. The structure is simple, the power transmission path is short, and the power transmission effect is good. Furthermore, by driving the second connecting part 23 located at the end of the steering knuckle 2, the driving effect is improved, and the steering knuckle 2 rotates smoothly.

[0039] In some embodiments of this application, the output shaft may be formed with an external spline, and the second connecting portion 23 may be formed with an internal spline. The external spline can mate with the internal spline so that the output shaft can be splinedly connected to the second connecting portion 23, thereby enabling the steering drive 4 to be driveably connected to the steering knuckle 2. By splinedly connecting the steering drive 4 to the steering knuckle 2, the connection stability can be improved, and the power transmission efficiency can be increased.

[0040] In some embodiments of this application, the internal spline of the second connecting part 23 can be constructed as a tapered spline. The tapered spline has axial positioning characteristics, which can position the mating position of the output shaft and the second connecting part 23 to reduce installation difficulty and assembly error. Furthermore, this configuration can make the surface contact stress distribution more uniform, effectively disperse alternating loads, reduce the risk of damage to the output shaft due to excessive stress, and help extend the service life of the output shaft.

[0041] In some embodiments of this application, the taper of the taper spline is Ø, which satisfies the relationship: 2°≤Ø≤5°. Ø can be 2°, 3°, 5°, etc. This setting is reasonable, reduces assembly errors, makes the surface contact stress distribution more uniform, effectively disperses alternating loads, and helps to extend the service life of the output shaft.

[0042] As a specific embodiment of this application, such as Figure 1 As shown, both the steering knuckle 2 and the fixing member 3 can be constructed as a C-shaped structure. The steering knuckle 2 and the fixing member 3 can jointly define the receiving space 5. At least a part of the steering actuator 4 can be received in the receiving space 5. The steering actuator 4 is enclosed by the receiving space 5 formed by the steering knuckle 2 and the fixing member 3. This arrangement can make the component layout of the corner module device 10 compact, so that the corner module device 10 occupies less space in the height direction of the vehicle, thereby improving the space utilization of the corner module device 10, providing more space for the vehicle to arrange other components, and is conducive to increasing the number of vehicle models that the corner module device 10 can adapt to, and is conducive to improving the adaptation range of the corner module device 10.

[0043] Along the height direction of the vehicle, such as Figure 1 As shown, the third connecting part 32 can be stacked on top of the first connecting part 22, and the third connecting part 32 can be located above the first connecting part 22. Both the first connecting part 22 and the third connecting part 32 can be located above the steering drive 4. The first connecting part 22 and the third connecting part 32 can be pivotally connected by a connector, such as a ball joint, bearing bolt, etc., so that the first connecting part 22 can rotate relative to the third connecting part 32 about the rotation axis of the steering knuckle 2.

[0044] Along the height direction of the vehicle, such as Figure 1 As shown, the fourth connecting part 33 can be stacked on top of the second connecting part 23, and the fourth connecting part 33 can be located above the second connecting part 23. Both the fourth connecting part 33 and the second connecting part 23 can be located below the steering drive 4. The second connecting part 23 and the fourth connecting part 33 can be pivotally connected by a connector, such as a ball joint, bearing bolt, etc., so that the second connecting part 23 can rotate relative to the fourth connecting part 33 about the rotation axis of the steering knuckle 2.

[0045] Furthermore, the fourth connecting portion 33 may have a clearance hole, the axis of which may coincide with the axis of the output shaft. The output shaft may pass through the clearance hole and be drively connected to the second connecting portion 23. The output shaft may transmit power to the second connecting portion 23 to drive the steering knuckle 2 to rotate around the axis of the steering knuckle 2, thereby driving the wheel assembly 1 to steer. In addition, the second connecting portion 23 and the fourth connecting portion 33 may provide support for the steering drive 4 to improve the placement stability of the steering drive 4. Moreover, this arrangement is compact to reduce the Z-axis dimension and improve the space utilization of the corner module device 10.

[0046] In some embodiments of this application, such as Figure 1 As shown, the corner module device 10 may further include: an upper control arm structure 6 and a lower control arm structure 7. The upper control arm structure 6 and the lower control arm structure 7 can be connected to the vehicle body or suspension via bushings. Both the upper control arm structure 6 and the lower control arm structure 7 can be hinged to the fixing member 3. The upper control arm structure 6 and the lower control arm structure 7 can be hinged to the fixing member 3 via connecting members. As some embodiments of this application, the connecting member can be a bolt and a bushing used in conjunction. As some embodiments of this application, the connecting member can be a cylindrical pin. The upper control arm structure 6 and the lower control arm structure 7 can control the vertical movement trajectory of the wheel and suppress the interference of lateral forces on the shock absorber, which is beneficial to improving steering accuracy and cornering handling. By hinged to the fixing member 3 and the upper control arm structure 6 and the lower control arm structure 7, the upper control arm structure 6 and the lower control arm structure 7 can rotate relative to the fixing member 3, so that the upper control arm structure 6 and the lower control arm structure 7 can bear longitudinal loads and lateral forces, and effectively absorb road impacts and transmit them to the vehicle body, which is beneficial to ensuring driving stability.

[0047] The vehicle according to the embodiments of this application includes the corner module device 10 of the above embodiments. By housing at least a portion of the steering drive 4 within the housing space 5, the component layout of the corner module device 10 is made compact, so that the corner module device 10 occupies less space in the height direction of the vehicle, thereby improving the space utilization of the corner module device 10, providing more space for arranging other components of the vehicle, and also facilitating an increase in the number of vehicle models that the corner module device 10 can adapt to, thus expanding the adaptability range of the corner module device 10.
