Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a corner module for a vehicle and a vehicle having the corner module. Background Technology

[0002] With the rapid development of vehicle technology, users are increasingly demanding higher motion efficiency from vehicle corner modules. However, the traditional mounting method for the lower bushing and bracket of the in-wheel motor shock absorber in existing technology typically employs an open-split bracket structure. This design requires the in-wheel motor bracket to extend inwards towards the vehicle along the motor axis, while also reserving sufficient tooling space in the X direction. This necessitates high bracket strength, resulting in an overly robust bracket structure that increases manufacturing costs and hinders weight reduction. Therefore, it is evident that existing corner modules still have significant room for improvement in terms of structural optimization, cost control, mechanical performance enhancement, and adaptability.

[0003] Therefore, there is a need to provide improved corner modules for vehicles and vehicles having such corner modules in order to at least partially solve the problems existing in the prior art. Utility Model Content

The corner module includes: a shock absorber assembly and a hub motor mounting bracket. The shock absorber assembly has a first end and a second end opposite to the first end. The hub motor mounting bracket has a first arm and a second arm. The first arm has a first inner side, and the second arm has a second inner side. The first inner side and the second inner side are respectively provided with a first protrusion and a second protrusion. The first protrusion and the second protrusion are respectively provided with a first mounting hole and a second mounting hole. The central axes of the first mounting hole and the second mounting hole are parallel to the X-direction. The first protrusion and the second protrusion are connected to the first end of the shock absorber assembly.

[0005] Optionally, the shock absorber assembly is provided with a lower shock absorber bushing at the first end, and the lower shock absorber bushing is provided with mounting holes at both ends. The shock absorber assembly is connected to the hub motor mounting bracket through the lower shock absorber bushing.

[0006] Optionally, the lower bushing of the shock absorber includes an inner tube, a rubber body, an outer tube, and a pin on the inner tube.

[0007] Optionally, the lower bushing rubber body is provided with a recess, and the lower bushing outer tube is press-fitted into the recess.

[0008] Optionally, the lower bushing inner tube pin is further provided with a limiting portion, and the lower bushing inner tube and the lower bushing rubber body abut against the limiting portion.

[0009] Optionally, the lower bushing rubber body is clamped between the limiting portions.

[0010] Optionally, the hub motor mounting bracket further has an outer side, which forms a first edge with the first inner side and a second edge with the second inner side. The first protrusion and the second protrusion are respectively a distance from the first edge and the second edge, such that when the lower bushing of the shock absorber is installed with the hub motor mounting bracket, the projection of the lower bushing of the shock absorber in the XZ plane is located within the projection of the hub motor mounting bracket in the XZ plane.

[0030] The exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is by no means a limitation of the present invention or its applications or uses. Furthermore, the dimensions and proportions of the components in the drawings are merely schematic and do not strictly correspond to actual products.

[0031] In a first aspect of this invention, a corner module 1 for a vehicle is provided. For example... Figures 1 to 11 As shown, the corner module 1 includes a shock absorber assembly 800 and a hub motor mounting bracket 700. The shock absorber assembly 800 has a first end 820 and a second end 830 opposite to the first end 820. The hub motor mounting bracket 700 has a first arm 750 and a second arm 760. The first arm 750 has a first inner side 751, and the second arm 760 has a second inner side 762. The first inner side 751 and the second inner side 762 are respectively provided with a first protrusion 710 and a second protrusion 720. The first protrusion 710 and the second protrusion 720 are respectively provided with a first mounting hole and a second mounting hole (not shown). The central axis of the first mounting hole and the second mounting hole is parallel to the X direction. The first protrusion 710 and the second protrusion 720 are connected to the first end 820 of the shock absorber assembly 80.

[0032] Specifically, in this embodiment, such as Figures 1 to 11 As shown, the hub motor mounting bracket 700 has a first arm 750 and a second arm 760, which are connected to each other by an upper beam to form an integral frame, thus making the hub motor mounting bracket 700 generally have an "n" shaped structure. A first protrusion 710 and a second protrusion 720 protrude from a first inner side 751 and a second inner side 762 in the Y direction, respectively, and the central axes of the first mounting hole on the first protrusion 710 and the second mounting hole on the second protrusion 720 are parallel to the X direction, which is parallel to the central axis of the hub motor 1300. The first end 820 of the shock absorber assembly 800 is provided with a dog-bone type mounting structure. This dog-bone type mounting structure has mounting holes, allowing the use of press-fit bolts 730. These bolts pass through the mounting holes of the dog-bone type mounting structure and the first and second mounting holes of the first protrusion 710 and the second protrusion 720, respectively, to press the dog-bone type mounting structure onto these protrusions, thus connecting the shock absorber assembly 800 to the hub motor mounting bracket 700. This design optimizes the layout, significantly reducing the space occupied by the hub motor mounting bracket 700 in the X direction, improving space utilization, and simultaneously reducing component weight, effectively enhancing the lightweight design. Furthermore, by rationally distributing the connection points, the structural strength of the hub motor mounting bracket 700 is significantly improved, increasing its support rigidity and stability, thereby achieving a balance between rigidity and lightweight design.

[0033] like Figures 1 to 5 as well as Figures 7 to 9 As shown, the shock absorber assembly 800 has a lower shock absorber bushing 850 at its first end 820. The lower shock absorber bushing 850 has mounting holes 863 at both ends. The shock absorber assembly 800 is connected to the hub motor mounting bracket 700 through the mounting holes 863 of the lower shock absorber bushing 850. Specifically, in this embodiment, the lower shock absorber bushing 850 has mounting holes 863 at both ends. The central axis of the mounting holes 863 is parallel to the X-direction. A press-fit bolt 730 can pass through the mounting holes 863, the first mounting hole, and the second mounting hole, connecting the lower shock absorber bushing 850 to the hub motor mounting bracket 700. In other words, in this embodiment, the lower shock absorber bushing 850 has a dog-bone mounting structure. By installing a lower bushing for the shock absorber, vibrations, noise, and impacts from the road surface can be effectively absorbed and attenuated, improving the vehicle's NVH (noise, vibration, and harshness) performance. This not only improves vehicle comfort but also protects the shock absorber itself and related connecting components from excessive impact stress and safeguards the system's durability.

[0034] like Figures 7 to 9 As shown, the lower bushing 850 of the shock absorber includes an inner tube 851, a rubber body 852, an outer tube 853, and a pin 861. The pin 861 is arranged axially on both sides of the inner tube 851 along the lower bushing 850. The inner tube 851, the rubber body 852, and the outer tube 853 are coaxially arranged. The pin 861 has a mounting portion 864. The mounting hole 863 is provided on the mounting portion 864. The central axis CC of the inner tube 851, the rubber body 852, and the outer tube 853 is perpendicular to the central axis of the mounting hole 863. Specifically, in this embodiment, in the installed state, the lower bushing rubber body 852 is arranged around the outside of the lower bushing inner tube 851, with the inner surface of the lower bushing rubber body 852 contacting the outer surface of the lower bushing inner tube 851. Similarly, the lower bushing outer tube 853 is arranged around the outside of the lower bushing rubber body 852, with the inner surface of the lower bushing outer tube 853 contacting the outer surface of the lower bushing rubber body 852. Furthermore, the damper lower bushing 850 has two lower bushing inner tube shaft pins 861 at its end. Each of the lower bushing inner tube shaft pins 861 has an approximately rectangular mounting portion with a damper lower bushing mounting hole. The central axes of the two damper lower bushing mounting holes are parallel to each other and perpendicular to the central axis CC of the lower bushing inner tube 851, the lower bushing rubber body 852, and the lower bushing outer tube 853. This arrangement ensures the installation accuracy and stability of the damper assembly 800, reduces wear, and provides better vibration damping.

[0035] like Figures 7 to 9 As shown, the lower bushing rubber body 852 has a recess, and the lower bushing outer tube 853 is press-fitted into the recess. By embedding the lower bushing outer tube 853 into the recess, the friction and contact area between the lower bushing outer tube 853 and the lower bushing rubber body 852 are increased, enhancing the bonding strength between the rubber body and the lower bushing outer tube 853. This effectively fixes the lower bushing outer tube 853 within the lower bushing rubber body 852, making it more stable when subjected to external impacts and vibrations. Furthermore, this structural design helps improve the overall seismic performance of the shock absorber assembly, preventing misalignment of the lower bushing outer tube 853 under prolonged use or extreme conditions, thereby extending the service life and performance of the shock absorber. Additionally, the recessed design effectively reduces wear caused by the relative movement between the lower bushing outer tube 853 and the lower bushing rubber body 852, further enhancing the system's stability and reliability.

[0036] like Figures 7 to 9As shown, the lower bushing inner tube pin 861 is also provided with a limiting portion 865, and the lower bushing inner tube 851 and the lower bushing rubber body 852 abut against the limiting portion 865. Specifically, in this embodiment, the lower bushing inner tube pin 861 is provided with a cylindrical portion and a limiting portion 865. In the installed state, the cylindrical portion of the lower bushing inner tube pin 861 is disposed inside the lower bushing inner tube 851 and contacts the inner surface of the lower bushing inner tube 851. The two cylindrical portions of the two lower bushing inner tube pins 861 are spaced apart by a certain gap in the axial direction CC of the lower bushing inner tube 851, so that the two ends of the lower bushing inner tube 851 and the two ends of the lower bushing rubber body 852 abut against the limiting portion 865. Figure 8 As shown in more detail, the lower bushing inner tube 851 is entirely clamped between two limiting portions 865, and the lower bushing rubber body 852 is also clamped between the limiting portions 865. This arrangement not only restricts the movement of the lower bushing inner tube shaft pin 861 into the lower bushing inner tube 851, but also prevents relative misalignment between the lower bushing inner tube 851 and the lower bushing rubber body 852 during use, increasing the overall stability of the damper lower bushing 850, thereby improving the vibration resistance and reliability of the damper assembly.

[0037] like Figures 2 to 6 As shown, the hub motor mounting bracket 700 also has an outer mounting bracket 770, which forms a first edge 771 with the first inner side 751, and a second edge 772 with the second inner side 762. The first protrusion 710 and the second protrusion 720 are respectively a distance from the first edge 771 and the second edge 772, such that when the lower damper bushing 850 is installed with the hub motor mounting bracket 700, the projection of the lower damper bushing 850 in the XZ plane is located within the projection of the hub motor mounting bracket 700 in the XZ plane. That is, in the installed state, the lower damper bushing 850 is completely positioned between the first arm 750 and the second arm 760 of the hub motor mounting bracket 700, thus optimizing the position of the central axis CC of the lower bushing inner tube 851, the lower bushing rubber body 852, and the lower bushing outer tube 853. Specifically, as... Figure 4As shown, in the prior art, the central axis of the lower bushing of the shock absorber is located at position U in the XZ plane, and the distance between position U and the wheel center O of the corner module is L. However, in the corner module of this invention, the central axes of the inner tube 851, rubber body 852, and outer tube 853 of the lower bushing are located at position U' in the XZ plane, and the distance between position U' and the wheel center O of the corner module is L'. This distance L' is significantly smaller than L. Therefore, this design significantly reduces the space occupied by the hub motor mounting bracket 700 in the X direction, improves space utilization, and reduces component weight, effectively enhancing the lightweighting level and possessing broad practicality and economic value.

[0038] like Figures 1 to 11 As shown, corner module 1 also includes a hub motor 1300, a shock absorber assembly 800, a hub motor mounting bracket 700, and the hub motor 1300, which are connected to each other by bolts. This design enhances the support rigidity of the hub motor mounting bracket, improves the stability of the overall structure, and significantly improves the installation reliability of the modular components. The detachable connection via bolts and other fasteners ensures easy disassembly and installation during maintenance and replacement, facilitating subsequent operation and repair.

[0039] like Figure 2 As shown, the central axes of the first and second mounting holes are parallel to the central axis of the lower bushing mounting hole 863 of the shock absorber. This arrangement ensures precise alignment and positioning of each component during installation, making the installation more stable and avoiding loosening or performance degradation that may result from component misalignment or deviation. It also further improves the seismic resistance and service life of the entire system.

[0040] In a second aspect of this invention, a vehicle is also provided, which is equipped with any of the aforementioned corner modules. For the sake of brevity, further details are omitted here.
