Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a chassis and a vehicle. Background Technology

[0002] As the automotive industry continues to advance towards high-quality development, the market is demanding faster upgrades and replacements of intelligent electric vehicles. To address this challenge, automakers are beginning to adopt a decoupled development approach for the body and chassis. Currently, many chassis designs are still based on the traditional non-load-bearing body's connected structure, or are optimizations and improvements on that structure.

[0003] The decoupled development of the vehicle body and chassis not only improves production efficiency and flexibility, but also opens up possibilities for achieving more advanced chassis technologies. One important research direction is how to achieve independent driving of the chassis. Utility Model Content

[0004] In view of the above problems, this application provides a chassis and vehicle that can improve the integration of the chassis and realize independent driving of the chassis.

[0005] In a first aspect, this application provides a vehicle chassis, the chassis including a lower body, a first front bulkhead, battery cells, and functional components. The lower body has a receiving cavity. The first front bulkhead is connected to the lower body. The battery cells are received in the receiving cavity. The functional components are disposed on the first front bulkhead.

[0006] In the above solution, by setting a first front bulkhead in the chassis, functional components are mounted on the first front bulkhead, allowing the chassis to be driven independently. This also simplifies the assembly structure of the chassis and upper body. This results in a chassis with high adaptability and a high degree of matching with the entire vehicle, adapting to the functional components required by different models and improving the chassis's integration. Furthermore, this high degree of integration and modularity can better simplify the number of parts and production steps, thereby reducing production costs.

[0007] In some embodiments, the lower body includes an energy compartment frame, which includes two first crossbeams disposed opposite each other along a first direction and two first longitudinal beams disposed opposite each other along a second direction. The first longitudinal beams are connected to the first crossbeams. The two first crossbeams and the two first longitudinal beams enclose a receiving cavity for accommodating a single battery cell, and the first and second directions intersect.

[0008] In the above solution, the battery cells are installed in the housing cavity, allowing the energy compartment frame to also function as a battery box. This reduces some redundant structures in traditional batteries, increases the vehicle's driving range, and achieves weight reduction and cost reduction. The energy compartment frame also protects the battery cells 30, reducing the risk of external impacts and improving reliability.

[0009] In some embodiments, the first front bulkhead is connected to two first longitudinal beams.

[0010] In the above solution, by connecting the first front bulkhead to two first longitudinal beams, the impact force can be dispersed onto the first longitudinal beams upon impact, thereby improving the safety performance of the passenger compartment. Simultaneously, modular design and assembly can be achieved, simplifying the production process and improving production efficiency.

[0011] In some embodiments, the first front bulkhead is connected to the first crossbeam.

[0012] In the above solution, by connecting the first front bulkhead to the first crossbeam, the impact force can be dispersed onto the first crossbeam upon impact, thereby improving the safety performance of the passenger compartment. Simultaneously, modular design and assembly can be achieved, simplifying the production process and improving production efficiency.

[0013] In some embodiments, the lower body further includes an energy compartment frame and a front compartment frame. The front compartment frame is connected to the energy compartment frame. The front compartment frame includes a front bumper beam, a second crossbeam, and two second longitudinal beams. The second crossbeam and the front bumper beam are arranged opposite each other along a first direction, and the two second longitudinal beams are arranged opposite each other along a second direction. The second longitudinal beams are connected to the second crossbeam and the front bumper beam.

[0014] In the above scheme, a front anti-collision beam, a second crossbeam, and two second longitudinal beams are set up, which together with other components form a roughly quadrilateral structure. This structure has good support stability and is easy to arrange other structures.

[0015] In some embodiments, the first front bulkhead and the second crossbeam are an integral structure.

[0016] The above solution helps reduce the number of connections, making the entire front area a whole, which helps improve the overall rigidity and strength of the structure, reduces the deformation of the chassis when subjected to external forces, simplifies the number of parts, simplifies the assembly process, and reduces production costs.

[0017] In some embodiments, the first front panel includes a main body and a reinforcing part, the reinforcing part protruding from the main body along the thickness direction of the main body.

[0018] In the above scheme, by setting a reinforcing part on the main body, the overall strength of the first front bulkhead is increased, thereby reducing the possibility of deformation of the first front bulkhead when it is impacted and improving the reliability of the chassis.

[0019] In some embodiments, the first front bulkhead is connected to the second crossbeam, which facilitates modular design and assembly, thereby improving adaptability to different vehicle models, simplifying the production process, and increasing production efficiency.

[0020] In some embodiments, the functional components include at least one of a braking system, a battery management system, a communication system, and a thermal management system.

[0021] In the above scheme, by integrating multiple functional components into the first front bulkhead, it is beneficial to improve the integration of the chassis, enabling independent driving of the chassis while improving the overall performance of the chassis.

[0022] In some embodiments, the functional components include a braking system and a thermal management system. The first front bulkhead includes a first mounting area and a second mounting area. The braking system is disposed in the first mounting area, and the thermal management system is disposed in the second mounting area. The first mounting area and the second mounting area are spaced apart.

[0023] In the above scheme, the front bulkhead is usually located at the front of the vehicle, close to the air intake. The thermal management system is installed on the front bulkhead, which can directly use the cold air in the front compartment of the vehicle for heat dissipation, improve cooling efficiency, and at the same time improve the space utilization of the front bulkhead and improve the integration of the chassis.

[0024] In some embodiments, the surface of the functional component facing away from the vehicle body does not exceed the surface of the first front bulkhead facing away from the vehicle body.

[0025] The above scheme, through the above settings, helps to reduce the possibility of interference between functional components and the upper body, thereby improving the chassis's adaptability to different vehicle models.

[0026] Secondly, embodiments of this application provide a battery device, including the chassis and upper body as described in any of the foregoing embodiments. The upper body and the chassis are detachably connected.

[0027] In some embodiments, the upper body includes a second front bulkhead, which is detachably connected to a first front bulkhead of the chassis.

[0028] In the above scheme, the first front bulkhead and the second front bulkhead are detachably connected to achieve separation, decoupling and connection of the first front bulkhead and the second front bulkhead, thereby enabling independent development of the upper body and chassis. At the same time, it increases the installation area of ​​functional components, allowing the chassis to be replaced and functions added as needed, shortening the development cycle and reducing costs.

[0029] In some embodiments, a sealing member is provided between the first front bulkhead and the second front bulkhead.

[0030] In the above solution, the sealing component can achieve a seal between the first front bulkhead and the second front bulkhead, reduce impurities entering the passenger compartment, improve passenger experience, and enhance vehicle reliability.

[0031] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0053] As the automotive industry continues to advance towards high-quality development, the market is demanding faster upgrades of intelligent electric vehicles. To address this challenge, automakers are beginning to adopt a decoupled development approach for the vehicle body and chassis. In traditional vehicle design, the decoupling surface between the chassis and the upper body is typically located between the front crossbeam and the front bulkhead, which is part of the upper body and is used to mount some key devices and systems.

[0054] However, this traditional design presents some challenges when developing a self-driving chassis. The lack of a front bulkhead in traditional vehicle chassis design means that many devices that would normally be mounted on the front bulkhead cannot be directly installed on the improved self-driving chassis.

[0055] The lack of a front bulkhead means these components lack suitable mounting locations, thus affecting the chassis's independent driving capability. These issues directly impact the chassis's independent driving function, limiting its performance and reliability.

[0056] To address the aforementioned technical problems, this application provides a technical solution that involves installing a first front bulkhead in the chassis to mount functional components, enabling the chassis to drive independently. This also simplifies the assembly structure of the chassis and upper body. This results in a highly adaptable chassis with a high degree of vehicle compatibility, allowing it to accommodate the functional components required by different vehicle models and improving the chassis's integration. Furthermore, this high degree of integration and modularity can better simplify the number of parts and production steps, thereby reducing production costs.

[0057] The technical solutions described in the embodiments of this application are applicable to vehicles. Vehicles can be gasoline-powered vehicles, natural gas-powered vehicles, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc.

[0058] Figure 1 This is a schematic diagram of the exploded structure of a vehicle provided in an embodiment of this application.

[0059] like Figure 1 As shown in the figure, this application embodiment provides a vehicle 100, which includes a chassis 1 and an upper body 2, with the upper body 2 connected to the chassis 1. The upper body 2 and the chassis 1 are detachably connected.

[0060] For example, the upper body 2 and the chassis 1 are detachably connected by a connector. This application does not limit the type of connector; in some examples, the connector may include at least one of bolts, nuts, studs, screws, and pins. In other examples, the connector may also include a snap-fit.

[0061] In this embodiment, the upper body 2 and the chassis 1 are detachably connected, which can realize the separation, decoupling and connection of the upper body 2 and the chassis 1, thereby enabling the independent development of the upper body 2 and the chassis 1. The upper body 2 and the chassis 1 can be replaced as needed, shortening the R&D cycle and reducing costs.

[0062] Figure 2 This is a partial structural diagram of the underbody of a chassis provided in an embodiment of this application. Figure 3 This is a partial cross-sectional structural diagram of a vehicle provided in an embodiment of this application.

[0063] like Figures 1 to 3 As shown, this application embodiment provides a chassis for a vehicle 100. The chassis 1 includes a lower body 10, a first front bulkhead 20, a battery cell 30, and functional components 40. The lower body 10 has a receiving cavity 11. The first front bulkhead 20 is connected to the lower body 10. The battery cell 30 is received in the receiving cavity 11. The functional components 40 are disposed on the first front bulkhead 20.

[0064] In some embodiments, the lower body 10 has one or more receiving cavities 11, each of which can house a battery cell 30. Optionally, the lower body 10 may include a cover 14, which may be disposed above the battery cell 30. Optionally, the cover 14 may be used as the floor of the passenger compartment of the vehicle 100, thereby saving parts of the vehicle 100, increasing the driving range of the vehicle 100, and achieving the effects of weight reduction and cost reduction.

[0065] In some embodiments, the battery cell 30 is connected to the cover plate 14. The cover plate 14 can support multiple battery cells 30.

[0066] In some embodiments, the battery cell 30 is bonded to the cover plate 14. Bonding the battery cell 30 to the cover plate 14 can also improve the overall rigidity of the cover plate 14 and reduce the deformation of the cover plate 14 when the vehicle 100 is involved in a collision.

[0067] In some embodiments, the lower body 10 may further include a protective plate 15, which is located below the battery cell 30 and covers the receiving cavity 11 from below. The protective plate 15 can seal the receiving cavity 11, reduce external impurities impacting the battery cell 30, and improve the cycle life of the battery cell 30.

[0068] The battery cell 30 can be the smallest unit capable of independent charging and discharging. The battery cell 30 may include a lithium-ion secondary battery cell 30, a lithium-sulfur battery cell 30, a sodium-lithium-ion battery cell 30, a sodium-ion battery cell 30, or a magnesium-ion battery cell 30, etc., and this application embodiment is not limited to this. The battery cell 30 may be cylindrical, flat, cuboid, or other shapes, and this application embodiment is not limited to this either. The battery cell 30 may be a cylindrical battery cell 30, a cuboid battery cell 30, or a pouch battery cell 30.

[0069] The first front bulkhead 20 serves as a crucial barrier separating the engine compartment and the driver's cab. It not only absorbs and transfers energy during a collision, providing sufficient rigidity to the vehicle frame, but also affects the overall vehicle sealing. Optionally, the bulkhead near the front of the vehicle can be referred to as the first front bulkhead 20. Optionally, the functional component 40 can be located on the side of the first front bulkhead 20 facing the engine compartment, or on the side of the first front bulkhead 20 facing the driver's cab.

[0070] In some examples, the first front bulkhead 20 and the second front bulkhead 60 of the upper body 2 are connected to form a complete front bulkhead that isolates the engine compartment and the cab.

[0071] In some examples, the first front bulkhead 20 may be provided with ventilation holes or ducts to guide hot or cold air into the vehicle interior, ensuring the effective operation of the air conditioning and ventilation systems.

[0072] Optionally, the first front bulkhead 20 may be provided with mounting holes, mounting bosses or other mounting structures for mounting the functional component 40.

[0073] Optionally, the chassis 1 may also include a drive system, a steering system, a braking system 41, and a control system. These devices can be respectively mounted on the lower body 10. The control system and the battery cell 30 are respectively connected to the input end of the drive system, and the output end of the drive system is connected to the wheels. At the same time, the control system is also connected to the input end of the steering system and the braking system 41, and the steering system and the braking system 41 and their output ends are respectively connected to the wheels, so that the chassis 1 integrates a system that can operate independently.

[0074] Optionally, functional component 40 may include some or all of the devices in the above system.

[0075] In this embodiment, the battery cell 30 is integrated on the chassis 1 to achieve the integration of CTC (Cell to Chassis) battery chassis 1.

[0076] This embodiment of the application provides a first front bulkhead 20 within the chassis 1, on which functional components 40 are mounted, enabling the chassis 1 to be driven independently. This also simplifies the assembly structure of the chassis 1 and the upper body 2. This results in high adaptability of the chassis 1, high compatibility with the overall vehicle, and the ability to accommodate the functional components 40 required by different vehicle models, thus improving the integration of the chassis 1. Furthermore, this high degree of integration and modularity can better simplify the number of parts and production steps, thereby reducing production costs.

[0077] like Figures 1 to 4 As shown, in some optional embodiments, the lower body 10 includes an energy compartment frame, which includes two first crossbeams 12 arranged opposite each other along a first direction X and two first longitudinal beams 13 arranged opposite each other along a second direction Y. The first longitudinal beams 13 are connected to the first crossbeams 12. The two first crossbeams 12 and the two first longitudinal beams 13 enclose a receiving cavity 11 for accommodating a battery cell 30, and the first direction X and the second direction Y intersect.

[0078] Optionally, the first direction X can be the width direction of the vehicle 100, and the second direction Y can be the length direction of the vehicle 100.

[0079] Optionally, the first longitudinal beam 13 can be directly connected to the first transverse beam 12, or it can be indirectly connected to the first transverse beam 12 through other components.

[0080] For example, two first crossbeams 12 are spaced apart along the second direction Y, and two first longitudinal beams 13 are spaced apart along the first direction X.

[0081] Optionally, the two first crossbeams 12 and the two first longitudinal beams 13 can be arranged alternately and connected end to end. The first longitudinal beam 13 can also extend beyond the first crossbeam 12 along its own length direction, and the first crossbeam 12 can also extend beyond the first longitudinal beam 13 along its own length direction.

[0082] This application does not limit whether the structures of the two first crossbeams 12 are the same; the structures of the two first crossbeams 12 can be the same or different. The same applies to the first longitudinal beam 13, which will not be described in detail here.

[0083] Optionally, the first direction X and the second direction Y are perpendicular.

[0084] In some embodiments, the two first crossbeams 12 and the two first longitudinal beams 13 can enclose a receiving cavity 11, in which the battery cell 30 is installed. This allows the energy compartment frame to function as a battery housing simultaneously, thereby reducing some redundant structures in traditional batteries, increasing the driving range of the vehicle 100, and achieving weight reduction and cost reduction. The energy compartment frame protects the battery cell 30, reducing the risk of the battery cell 30 being subjected to external impacts and improving reliability. In some examples, the cover plate 14 is fixedly connected to the first crossbeam 12. In other examples, the cover plate 14 is detachably connected to the first crossbeam 12; exemplaryly, the cover plate 14 can be bolted to the first crossbeam 12. In some examples, the cover plate 14 is fixedly connected to the first longitudinal beam 13. In other examples, the cover plate 14 is detachably connected to the first longitudinal beam 13; exemplaryly, the cover plate 14 can be bolted to the first longitudinal beam 13.

[0085] like Figures 1 to 4 As shown, in some alternative embodiments, the first front bulkhead 20 is connected to two first longitudinal beams 13.

[0086] Optionally, the first front bulkhead 20 can be directly connected to the first longitudinal beam 13, or it can be indirectly connected to the first longitudinal beam 13 through other components.

[0087] Optionally, the first front bulkhead 20 can be formed by stamping or other methods.

[0088] Optionally, the first front bulkhead 20 can be connected to the first longitudinal beam 13 by welding, riveting, bolting, or other means.

[0089] Optionally, the lower body 10 may also include a shock absorber tower 50, which can be directly connected to the first front bulkhead 20, or can be detachably connected via a connector.

[0090] For example, the shock absorber tower 50 is a metal structural component mounted on the vehicle shock absorber, and the shock absorber and shock absorber spring of the suspension system can be mounted on the shock absorber tower 50.

[0091] This embodiment of the application connects the first front bulkhead 20 to two first longitudinal beams 13, so that when the first front bulkhead 20 is subjected to an impact, the impact force can be dispersed to the first longitudinal beams 13, thereby improving the safety performance of the passenger compartment. At the same time, it can also realize modular design and assembly, simplify the production process, and improve production efficiency.

[0092] like Figures 1 to 4 As shown, in some alternative embodiments, the first front bulkhead 20 is connected to the first crossbeam 12.

[0093] It is understood that the number of first crossbeams 12 includes two, one of which is close to the front of the vehicle 100 and the other is close to the rear of the vehicle 100. The first front bulkhead 20 is connected to the first crossbeam 12 close to the front of the vehicle 100.

[0094] This embodiment of the application connects the first front bulkhead 20 to the first crossbeam 12, so that the first front bulkhead 20 can disperse the impact force onto the first crossbeam 12 when it is hit, thereby improving the safety performance of the passenger compartment. At the same time, it can also realize modular design and assembly, simplify the production process, and improve production efficiency.

[0095] like Figures 1 to 4 As shown, in some optional embodiments, the lower body 10 further includes an energy compartment frame and a front compartment frame. The front compartment frame is connected to the energy compartment frame. The front compartment frame includes a front anti-collision beam 18, a second crossbeam 16, and two second longitudinal beams 17. The second crossbeam 16 and the front anti-collision beam 18 are arranged opposite each other along a first direction X, and the two second longitudinal beams 17 are arranged opposite each other along a second direction Y. The second longitudinal beams 17 are connected to the second crossbeam 16 and the front anti-collision beam 18.

[0096] This application does not limit the connection method between the second longitudinal beam 17, the second cross beam 16, and the front bumper beam 18. Exemplarily, the second longitudinal beam 17 and the second cross beam 16 can be connected by integral molding, welding, threaded connection, riveting, or FDS (Front-Drop Wire) connection. The same applies to the second longitudinal beam 17 and the front bumper beam 18, which will not be elaborated further in this application.

[0097] Optionally, the first direction X and the second direction Y are perpendicular.

[0098] The front anti-collision beam 18, the second crossbeam 16, and the two second longitudinal beams 17 are provided to form a roughly quadrilateral structure, either by themselves or by combining with other components. This structure has good support stability and is easy to arrange other structures. Figure 4 This is a schematic diagram of the underbody structure of a chassis provided in an embodiment of this application. Figure 5 This is a partial cross-sectional structural schematic diagram of another vehicle provided in the embodiments of this application.

[0099] like Figure 1 , Figure 2 as well as Figure 4 and Figure 5 As shown, in some alternative embodiments, the first front bulkhead 20 and the second crossbeam 16 are an integral structure.

[0100] Optionally, the integrated structure formed by the first front bulkhead 20 and the second crossbeam 16 can be plate-shaped as a whole, with a plate-shaped structure provided in the area where the first front bulkhead 20 is located to form the first front bulkhead 20, and a reinforcing structure provided in the area where the second crossbeam 16 is located to form the second crossbeam 16.

[0101] Optionally, the second crossbeam 16 and the first crossbeam 12 can be connected by the first front bulkhead.

[0102] The embodiments of this application, through the above-described configuration, help to reduce the number of connections, making the entire front area a whole, which helps to improve the overall rigidity and strength of the structure, reduce the deformation of the chassis 1 when subjected to external forces, and at the same time simplify the number of parts, simplify the assembly process, and reduce production costs.

[0103] like Figure 1 , Figure 2 as well as Figure 4 and Figure 5 As shown, in some alternative embodiments, the first front panel 20 includes a main body 21 and a reinforcing part 22, the reinforcing part protruding from the main body 21 along the thickness direction of the main body 21.

[0104] Optionally, the number of reinforcing parts 22 may include multiple reinforcing parts 22, which are spaced apart.

[0105] Optionally, the reinforcing part 22 can be a reinforcing rib.

[0106] Optionally, the reinforcing part 22 may extend along the first direction X or along the second direction Y.

[0107] Optionally, the main body 21 can be a plate-like structure. Optionally, the main body 21 can be a single plate-like structure or a multi-layer plate-like structure. For example, when the main body 21 is a multi-layer plate-like structure, the reinforcing part 22 can be located between the multi-layer plate-like structures. For example, when the main body 21 is a single plate-like structure, the two sides of the first front bulkhead 20 along the thickness direction are a first side facing the front compartment of the vehicle 100 and a second side facing the energy compartment of the vehicle 100, respectively. The reinforcing part 22 can be provided only on the first side, only on the second side, or both on the first and second sides. The energy compartment of the vehicle 100 can be the space in the middle of the vehicle 100 where the battery cells 30 are stored, and the front compartment of the vehicle 100 can be the space at the front of the vehicle 100.

[0108] In this embodiment of the application, a reinforcing part 22 is provided on the main body 21 to increase the overall strength of the first front bulkhead 20, thereby reducing the possibility of deformation of the first front bulkhead 20 when subjected to an impact and improving the reliability of the chassis 1.

[0109] like Figures 1 to 4As shown, in some alternative embodiments, the first front bulkhead 20 is connected to the second crossbeam 16.

[0110] Optionally, the first front bulkhead 20 and the second crossbeam 16 are separate structures, and the first front bulkhead 20 and the second crossbeam 16 can be fixedly connected by bolts, welding or other means.

[0111] The embodiments of this application, through the above-described settings, facilitate modular design and assembly, thereby improving adaptability to different vehicle models, simplifying the production process, and increasing production efficiency.

[0112] In some alternative embodiments, functional component 40 includes at least one of braking system 41, battery management system, communication system, and thermal management system 42.
