Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, specifically to a modular support, suspension system, and vehicle. Background Technology

[0002] The suspension system is the structure that connects the vehicle frame and the wheels. In the field of traditional power vehicles, engine power is transmitted to the wheels through a series of transmission devices and drive shafts. The suspension system needs to be designed to avoid the transmission devices, which takes up a lot of space and has poor versatility.

[0003] New energy vehicles represent the future direction of automotive development, and electric wheels are one technological approach within this field. Electric wheels can eliminate many transmission components, providing more installation space for batteries and other auxiliary mechanisms. Each wheel can be controlled independently, enabling complex drive configurations. However, thermal management must be considered for electric wheels, as the limited size of the in-wheel motor necessitates efficient cooling within a confined space. Existing suspension systems cannot fully utilize the advantages of electric wheels and are not conducive to the arrangement of electric wheel cooling systems. Therefore, developing a suspension system that is suitable for and leverages the advantages of electric wheels is an urgent task to be addressed.

[0004] In summary, existing suspension systems suffer from poor versatility and fail to meet the usage requirements of some vehicles. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a modular support, suspension system, and vehicle. The modular support provides mounting positions for cooling pipes of cantilever arms and wheels, while also providing connection interfaces for the vehicle frame or steering system. By standardizing and integrating the structure of the modular support, it achieves a compact and versatile structure with minimal space occupation, enabling modular design, production, installation, and replacement of the suspension system.

[0006] The solution to achieve the technical objective of this invention is a modular support, comprising:

[0007] The body has a first part and a second part set at an angle. The first part is provided with a slewing interface for connecting to a vehicle frame or steering system, and the second part is provided with a cantilever mounting interface. The cantilever mounting interface and the slewing interface are arranged sequentially from bottom to top and are both located on the first side of the body.

[0008] A cover plate is connected to the body and together with the body forms a pipeline arrangement cavity. The pipeline arrangement cavity and the cantilever mounting interface are located on the second side of the body opposite to the first side.

[0009] The rotary interface has a central through hole for pipes to pass through; the modular support is provided with at least two cable passages that communicate with the pipe arrangement cavity, and the cable passages lead to the first side.

[0010] In some embodiments, the body includes a base plate and two outer side plates connected to both sides of the base plate, wherein the base plate and the outer side plates are both bent plates to form a first part and a second part.

[0011] In some embodiments, the two sides of the base plate are respectively connected to the middle of the two outer side plates, or the outer side plate protrudes from one side of the base plate and a groove is formed on the other side of the base plate, so as to form two receiving spaces on both sides of the base plate, one of which, together with the cover plate, forms the pipeline arrangement cavity.

[0012] In some embodiments, the rotary interface has at least one ring of connecting holes arranged circumferentially along the central through hole; the modular support is connected to the frame or steering system via threaded fasteners provided in the connecting holes.

[0013] In some embodiments, the rotary interface is a cover connected to the end of the second part; the central through hole and the connecting hole are both located on the top surface of the cover and are in communication with the cavity of the cover.

[0014] In some embodiments, the side of the housing is provided with a neck wire hole communicating with the cavity of the housing, and the neck wire hole leads to the wire passage.

[0015] In some embodiments, at least one of the base plate and the two outer side plates is provided with a weight-reducing groove; the base plate is also provided with a group of reinforcing ribs arranged at an angle to each other, and at least some of the reinforcing ribs in the group of reinforcing ribs are connected to one or both of the outer side plates.

[0016] In some embodiments, the first part is further provided with a gas spring mounting interface, which is located above the cantilever mounting interface; the cantilever mounting interface includes an upper arm interface and a lower arm interface that are spaced apart.

[0017] Based on the same inventive concept, the present invention also provides a suspension system including the aforementioned modular support.

[0018] Based on the same inventive concept, the present invention also provides a vehicle including the above-described suspension system.

[0019] As can be seen from the above technical solution, the modular support provided by the present invention includes a body and a cover plate. The body has a first part and a second part arranged at an angle. The first part is provided with a rotary interface for connecting to the vehicle frame or steering system, and the second part is provided with a cantilever mounting interface. The cantilever mounting interface and the rotary interface are arranged sequentially from bottom to top and are both located on the first side of the body to meet the connection requirements between the modular support and the wheel, vehicle frame / steering system, while making full use of space and improving the applicability of the modular support. The cover plate is connected to the body and together with the body forms a pipeline arrangement cavity. The pipeline arrangement cavity and the cantilever mounting interface are located on the second side of the body opposite to the first side. That is, a space is provided on the opposite side connecting the modular support to the cantilever and connecting the wheel to accommodate the space required for wheel thermal management. This ensures that the arrangement of the pipelines required for wheel cooling on the cantilever and wheel mounting side does not interfere with the structures such as the cantilever located on the first side, facilitating assembly and management. The rotary interface has a central through hole for pipes to pass through; the modular support is provided with at least two cable passages connected to the pipe arrangement cavity. The cable passages lead to the first side. The cooling pipes required by the wheel are introduced into the space of the frame through the central through hole of the modular support and the corresponding through hole of the object component. The modular support provides support and positioning for the pipes, and the pipes are arranged in a dedicated pipe arrangement cavity. The pipe routing is neat and orderly. With the use of a cover plate, the pipes can be protected. This can meet the cooling needs of different wheels and provide a feasible arrangement scheme for the thermal management of the wheels.

[0020] The modular support provided by this invention, when connected to the vehicle frame via a rotary interface, functions similarly to the existing fixed connection between the frame and suspension. When the wheel steers, the modular support is fixed relative to the frame, while the wheel rotates relative to the modular support under the action of the cantilever and steering knuckle. When connected to the steering system via the rotary interface, the modular support is hinged to the wheel via the cantilever. The steering system drives the modular support to rotate, which in turn drives the wheel, enabling 360° steering of the suspension relative to the frame. This allows for individual control of each electric wheel, enabling various driving modes such as diagonal driving, lateral driving, and stationary turning, meeting different driving needs and effectively improving the vehicle's maneuverability. The modular support provides mounting positions for the cantilever, wheel cooling pipes, etc., and also provides connection interfaces for the frame or steering system. Through standardized and integrated design of the modular support structure, it is compact, highly versatile, and occupies little space, enabling modular design, production, installation, and replacement of the suspension system.

[0034] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] To address the technical problem of poor versatility and inability to meet the needs of some vehicles in existing suspension systems, this invention provides a modular support, suspension system, and vehicle. The modular support provides mounting positions for cantilever arms, wheel cooling pipes, etc., and also provides connection interfaces for the chassis or steering system. Through standardized and integrated design of the modular support structure, it achieves a compact and highly versatile structure with minimal space occupation, enabling modular design, production, installation, and replacement of the suspension system. The invention is further described in detail below through three specific embodiments:

[0036] Example 1

[0037] like Figures 1-7 As shown, this embodiment provides a modular support 100, including a body 110 and a cover plate 140. The body 110 has a first part 111 and a second part 112 arranged at an angle. The first part 111 is provided with a rotary interface 120 for connecting the frame 600 or the steering system, and the second part 112 is provided with a cantilever mounting interface 130. The cantilever mounting interface 130 and the rotary interface 120 are arranged sequentially from bottom to top and are both located on the first side 113 of the body 110 to meet the connection requirements between the modular support 100 and the wheel, frame 600 / steering system. At the same time, since the cantilever mounting interface 130 and the rotary interface 120 are both located on the first side 113 of the body 110, the cantilever mounting interface 130 and the rotary interface 120 can have enough space to make full use of space and improve the applicability of the modular support 100. The cover plate 140 is connected to the body 110 and together with the body 110 forms a pipe arrangement cavity 150. The pipe arrangement cavity 150 and the cantilever mounting interface 130 are located on the second side 114 of the body 110 opposite to the first side 113. That is, on the side opposite to the cantilever and wheel connected to the modular support 100, a space is provided to accommodate the heat management of the wheel. This ensures that the arrangement of the pipes 400 required for wheel cooling on the cantilever and wheel mounting side does not interfere with the structure such as the cantilever located on the first side 113, which is convenient for assembly and management. The rotary interface 120 has a central through hole 121 for the pipe 400 to pass through; the modular support 100 is provided with at least two cable passages 160 that communicate with the pipe arrangement cavity 150. The cable passages 160 lead to the first side 113. The pipes 400 of the cooling system required by the wheel are introduced into the space of the frame 600 through the central through hole 121 of the modular support 100 and the corresponding through hole of the object. The modular support 100 provides support and positioning for the pipes 400, and the pipes 400 are arranged in a dedicated pipe arrangement cavity 150. The pipes 400 are neatly and orderly arranged. With the use of the cover plate 140, the pipes 400 can be protected. This can meet the cooling needs of different wheels and provide a feasible arrangement scheme for the thermal management of the wheel.

[0038] The modular support 100 provided by this invention, when fixedly connected to the frame 600 via the rotary interface 120, is the same as the prior art scheme in which the frame 600 is fixedly connected to the suspension. When the wheel is turning, the modular support 100 is fixed relative to the frame 600, and the wheel rotates relative to the modular support 100 under the action of the cantilever and the steering knuckle. When connected to the steering system via the rotary interface 120, the modular support 100 is hinged to the wheel via the cantilever. The steering system drives the modular support 100 to rotate, which in turn drives the wheel to rotate, realizing the 360° steering function of the suspension relative to the frame 600. It can take advantage of the feature that each wheel of the electric wheel can be controlled independently, realizing multiple driving modes such as diagonal driving, lateral driving, and stationary turning, meeting different driving needs, and effectively improving the maneuverability of the car. The modular support 100 provides mounting positions for the cooling system pipes 400 of the cantilever and wheels, and also provides connection interfaces for the frame 600 or steering system. By standardizing and integrating the structure of the modular support 100, it is compact, versatile, and occupies little space, realizing the modular design, production, installation and replacement of the suspension system.

[0039] like Figures 1-5 As shown, this embodiment does not specifically limit the structure and forming method of the body 110. The body 110 can be a one-piece structure or multiple structures welded together. Based on the shape of the body 110, in one embodiment, the body 110 includes a base plate 115 and two outer side plates 116 connected to both sides of the base plate 115. The base plate 115 and the outer side plates 116 are both bent plates to form the first part 111 and the second part 112.

[0040] To facilitate molding and assembly with other suspension components, such as the suspension itself, preferably in this embodiment, the base plate 115 is perpendicular to both outer plates 116.

[0041] like Figures 2-3 As shown, this embodiment does not specifically limit the forming method of the pipeline arrangement cavity 150. As a feasible implementation method, the two sides of the bottom plate 115 are respectively connected to the middle of the two outer side plates 116, or the outer side plates 116 protrude from one side of the bottom plate 115 and the other side of the bottom plate 115 is provided with a groove, so as to form two receiving spaces on both sides of the bottom plate 115, one of which is enclosed by the cover plate 140 to form the pipeline arrangement cavity 150.

[0042] like Figures 2-5 As shown, in order to adapt to the needs of different vehicles and achieve different functions, in this embodiment, the rotary interface 120 is provided with at least one ring of connecting holes 122 arranged circumferentially along the central through hole 121; the modular support 100 is connected to the frame 600 or the steering system through threaded fasteners provided in the connecting holes 122.

[0043] When the modular support 100 is fixedly connected to the frame 600 via the rotary interface 120, the connecting hole 122 is only used to install threaded fasteners connecting to the frame 600. When the modular support 100 is fixedly connected to the output shaft of the steering system via the rotary interface 120 to achieve the technical effect of the suspension and wheels rotating relative to the frame 600, as a preferred embodiment, the modular support 100 still needs to have a connection with the frame 600, but it is still necessary to ensure that the modular support 100 can rotate relative to the frame 600 with the output shaft of the steering system, so that the frame 600 can bear the force between the wheel and the suspension and improve the overall support strength.

[0044] This embodiment does not limit the specific connection structure between the modular support 100 and the frame 600. For example, in some embodiments, an axially positioned, radially rotatable outer bushing can be added to the output shaft of the steering system. The outer bushing is fixedly connected to the bottom of the frame 600. Then, after the output shaft is fixedly connected to the rotary interface 120, the force between the modular support 100, the wheel, and the ground is stably transmitted to the frame 600 by the outer bushing. In some embodiments, the frame 600 and the modular support 100 can also be indirectly connected through a rotary support 300 connected to the frame 600. Specifically, for example... Figure 6 As shown, the slewing support 300 has an inner ring and an outer ring that can rotate relative to each other. One of the inner rings is fixedly connected to the frame 600, and the other is fixedly connected to the slewing interface 120. The slewing support 300 is coaxial with the central through hole 121 and the output shaft of the steering system. At this time, the connecting hole 122 of the slewing interface 120 has at least two turns. The connecting hole 122 of the inner ring is used to install the threaded fastener for connecting the output shaft, and the connecting hole 122 of the outer ring is used to install the threaded fastener for connecting the slewing support 300. The output shaft of the steering system is not shown in the figure. Figure 6 Of the two rings of bolts shown, the inner ring bolt passes through the connecting hole 122 on the outer ring of the rotary interface 120 to connect the inner ring of the rotary interface 120 and the rotary support 300, and the outer ring bolt connects the frame 600 and the outer ring of the rotary support 300.

[0045] In order to further control the weight of the modular support 100 while meeting the structural strength requirements, the rotary interface 120 is a cover connected to the end of the second part 112; the central through hole 121 and the connecting hole 122 are both located on the top surface of the cover and are connected to the cavity of the cover.

[0046] like Figure 5As shown, in order to further facilitate the arrangement and installation of the cooling system pipes 400 and to avoid the components installed on the modular support 100, in this embodiment, the side of the cover is provided with a neck wire hole 123 that communicates with the cavity of the cover. The neck wire hole 123 leads to the wire passage 160. That is, in this solution, the pipes 400 of the vehicle cooling system used to cool the wheels pass through the central cavity of the output shaft, then pass through the central through hole 121 and the neck wire hole 123 in sequence, and then enter the pipe arrangement cavity 150 for arrangement through the wire passage 160 near the neck wire hole 123. Finally, they pass out through the wire passage 160 near the cantilever mounting interface 130 and are supported and connected to the wheel by the cantilever assembly 200.

[0047] In order to control the weight of the modular support 100, in this embodiment, as follows: Figures 1-6 As shown, at least one of the two outer side plates 116 on the base plate 115 is provided with a weight-reducing part 118. As an optional embodiment, the weight-reducing part 118 provided on the outer side plate 116 can be a through hole; the weight-reducing part 118 on the base plate 115 can be a blind groove or a through hole. When the weight-reducing part 118 on the base plate 115 is a through hole, in some embodiments, the through hole can be directly used as a wire passage 160. The specific implementation can be adapted according to actual needs, and this embodiment does not impose specific limitations.

[0048] To enhance the connection strength between the base plate 115 and the side plate, and to ensure the support strength of the modular support 100, in this embodiment, as follows: Figure 1 , Figure 2 , Figures 5-6 As shown, the base plate 115 is also provided with a group of reinforcing ribs arranged at an angle to each other. At least some of the reinforcing ribs 117 in the group of reinforcing ribs are connected to one or two outer plates 116. That is, the reinforcing ribs 117 can be provided only on the base plate 115, or they can connect the base plate 115 and one of the outer plates 116, or they can connect the base plate 115 and two outer plates 116.

[0049] This embodiment does not limit the extension direction of the reinforcing ribs 117 or the angle between them. As a preferred embodiment, the reinforcing rib group includes two types of reinforcing ribs 117, one with an extension direction parallel to the outer plate 116 and the other with an extension direction perpendicular to the outer plate 116, in order to optimize the structural strength of the bottom plate 115 and the outer plate 116.

[0050] As one implementation method, in order to achieve shock absorption and adjust the vehicle height in conjunction with other components, the first part 111 is also provided with a gas spring mounting interface 170, such as... Figure 1 As shown, the gas spring mounting interface 170 is located above the cantilever mounting interface 130.

[0051] In order to stably transmit the torque between the wheel and the frame 600, in this embodiment, the cantilever mounting interface 130 includes an upper arm interface 131 and a lower arm interface 132 that are spaced apart in the height direction.

[0052] As one implementation method, such as Figure 1 and Figure 2 As shown, both the cantilever mounting interface 130 and the gas spring mounting interface 170 include two mounting seats respectively provided on the two outer side plates 116, and the mounting seats have mounting holes for the pin shaft to pass through. To ensure the strength of the mounting seats, preferably, the mounting seats are supported by reinforcing ribs 117.

[0053] As an example, Figure 6 This is a schematic diagram illustrating an application scenario for the modular support 100. The modular support 100's swivel interface 120 is fixedly connected to the steering system and rotatably connected to the vehicle frame 600 via the swivel support 300. The suspension arm and gas spring 500 are respectively connected to the suspension arm mounting interface 130 and gas spring mounting interface 170 on the first side 113 of the modular support 100 via pins. The pipeline 400 is arranged within the pipeline arrangement cavity 150 on the second side 114. The modular support 100 is bolted to the inner ring of the swivel support 300 via the outer ring connecting hole 122 of the swivel interface 120 and the bolt hole of the inner ring of the swivel support 300. The outer ring of the 00 is fixed to the frame 600 by bolts. The inner and outer rings of the slewing support 300 can rotate relative to each other, realizing the rotational movement of the modular support 100 relative to the frame 600. The modular support 100 is connected to the flange hole at the end of the output shaft of the steering system through the inner ring connecting hole 122 on its slewing interface 120. The steering torque provided by the steering system can be transmitted to the modular support 100 through the output shaft, realizing the active steering function and other mode control functions of the entire suspension system.

[0054] Example 2

[0055] Based on the same inventive concept, this embodiment provides a suspension system, including the modular support 100 provided in embodiment 1, and the two ends of the cantilever assembly 200 are respectively hinged to the cantilever mounting interface 130 and the wheel to meet the wheel bounce during driving.

[0056] When the swivel interface 120 of the modular support 100 is fixedly connected to the frame 600, since the suspension cannot rotate relative to the frame 600, a shock-absorbing spring can be installed between the wheel and the frame 600 to achieve wheel shock absorption. When the swivel interface 120 of the modular support 100 is fixedly connected to the output shaft of the steering system used for steering control, the suspension drives the wheel to rotate under the action of the output shaft. The suspension and the wheel rotate relative to the frame 600 as a whole. In order to achieve shock absorption and to adjust the suspension height in combination with other components, the first part 111 is also provided with a gas spring mounting interface 170. The gas spring mounting interface 170 is located above the cantilever mounting interface 130. One end of the gas spring 500 is rotatably mounted to the gas spring mounting interface 170 through a pin, and the other end can be rotatably connected to the upper or lower cantilever through a pin or hinged to the non-rotating part of the wheel. This embodiment is not limited to any of these, and can be adapted to the needs of the vehicle.

[0057] Example 3

[0058] Based on the same inventive concept, this embodiment provides a vehicle including the suspension system of Embodiment 2, which naturally possesses all the aforementioned beneficial effects. This invention does not specifically limit the type or category of the vehicle; it can be any type of vehicle in the prior art, such as a passenger car, bus, or truck. Other undescribed structures of the vehicle can be referred to relevant prior art disclosures, and will not be elaborated here.

[0059] In summary, the modular support 100, suspension system, and vehicle provided by this invention have at least the following beneficial effects:

[0060] The modular support 100 provided by this invention mainly consists of a detachably connectable body 110 and a cover plate 140. The modular support 100 provides installation interfaces for components of the suspension system such as the cantilever, air spring 500, and piping 400. The piping 400 is arranged in a dedicated space, with a neat and orderly routing. The cover plate 140, used in conjunction with the modular support 100, provides protection for the piping 400. The modular support 100 standardizes and integrates the air spring 500 interface, suspension arm interface, frame 600 interface, and piping 400 arrangement space, resulting in a compact structure that occupies little space, enabling modular design, production, installation, and replacement of the suspension system.

[0061] The modular support 100 of the present invention is fixedly connected to the output shaft of the steering system and can rotate relative to the frame 600 when the frame 600 can rotate. This enables the suspension system to rotate relative to the frame 600, achieving a 360° steering function for the suspension relative to the frame 600. It can take advantage of the characteristic that each wheel of the electric wheel can be controlled independently, realizing multiple driving modes such as diagonal driving, lateral driving, and stationary turning, meeting different driving needs and effectively improving the maneuverability of the vehicle.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
