[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0034] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0036] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0037] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0038] The term "plurality" used in this application refers to two or more (including two).

[0039] In related technologies, the upper and lower bodies are first connected as a whole before being assembled with the battery, electric drive, and other components. However, once connected, the upper and lower bodies are difficult to decouple. This limits their design and structure during R&D, making it difficult to change the lower body, resulting in long R&D cycles and high vehicle costs.

[0040] In view of this, an embodiment of the present application provides a technical solution, which sets a connecting structure on the upper body so that the lower body and the upper body can be detachably connected through a connecting piece, thereby realizing the separation and decoupling of the upper body and the lower body, so that the lower body can be replaced according to needs, shortening the R&D cycle and reducing costs.

[0041] The technical solutions described in the embodiments of this application are applicable to chassis and vehicles. The vehicles can be fuel vehicles, gas vehicles or new energy vehicles. The new energy vehicles can be pure electric vehicles, hybrid vehicles or extended-range vehicles, etc.

[0042] Figure 1 is an exploded schematic diagram of a vehicle provided in some embodiments of the present application; Figure 2 is a partial cross-sectional schematic diagram of the vehicle shown in Figure 1; and Figure 3 is a structural schematic diagram of an upper vehicle body provided in some embodiments of the present application.

[0043] As shown in FIG. 1 to FIG. 3 , an embodiment of the present application provides a vehicle, which includes an upper body 1 and a lower body 2 , wherein the upper body 1 is connected to the lower body 2 .

[0046] The embodiment of the present application does not limit the type of connection structure 1a. The connection structure 1a can be a structure such as a hole, a groove, or a structure such as a bolt, a stud, a pin, or other structures that can cooperate with the connecting member 3 to detachably connect the lower body 2 and the upper body 1.

[0047] In some examples, the connection structure 1a may include a through-hole, and the connection member 3 may include a bolt that passes through the through-hole and is threadedly connected to the lower body 2 to detachably connect the upper body 1 and the lower body 2. In other examples, the connection structure 1a may include a threaded hole, and the connection member 3 may include a bolt that passes through the lower body 2 and is threadedly connected to the wall of the threaded hole to detachably connect the upper body 1 and the lower body 2. In still other examples, the connection structure 1a may include a bolt integrated into the upper body 1, and the connection member 3 may include a nut. The bolt of the upper body 1 passes through the lower body 2 and is threadedly engaged with the nut to detachably connect the upper body 1 and the lower body 2.

[0048] It should be noted that the above examples are only for illustrating the connection structure 1a. The connection structure 1a is not limited to the above three structures. The connection structure 1a can also be in other forms, such as screws, slots, pins or other structures.

[0049] The number of the connecting structure 1a may be one or more.

[0050] In some examples, there are multiple connection structures 1a. The multiple connection structures 1a can have the same structure, for example, all of the multiple connection structures 1a are through holes or all of the multiple connection structures 1a are bolts. Alternatively, the multiple connection structures 1a can have different structures, for example, some of the connection structures 1a are plain holes and some of the connection structures 1a are threaded holes.

[0051] The embodiment of the present application provides a connection structure 1a on the upper body 1, so that the lower body 2 and the upper body 1 can be detachably connected via a connector 3, thereby achieving separation and decoupling of the upper body 1 and the lower body 2. This allows the lower body 2 to be replaced as needed, shortening the development cycle and reducing costs. The upper body 1 can be matched with lower bodies 2 of different shapes, meeting the user's demand for diverse shapes.

[0052] In some embodiments, the connection structure 1 a includes a connection hole.

[0053] The connection hole can be a through hole or a blind hole. The connection hole can be a plain hole or a threaded hole.

[0054] By providing the connection hole, the connection member 3 can be inserted into the connection hole to detachably connect the upper vehicle body 1 and the lower vehicle body 2. The connection hole is easy to form, which can simplify the forming process of the upper vehicle body 1.

[0055] In some embodiments, the connection hole is a plain hole. For example, a bolt, stud or the like can pass through the connection hole and be threadedly connected to the lower body 2 to detachably connect the upper body 1 and the lower body 2 .

[0056] In another embodiment, the connecting hole is a threaded hole, and the hole wall of the connecting hole can be threadedly connected to the connecting member 3 to facilitate detachable connection between the upper body 1 and the connecting member 3.

[0057] In some embodiments, the axial direction of the connecting hole is parallel to the height direction Z of the upper vehicle body 1 .

[0058] The height direction Z of the vehicle body may be the height direction Z of the vehicle body in a driving state.

[0059] The connecting member 3 can extend into the connecting hole along the height direction Z, which makes it easy to disassemble and assemble the connecting member 3.

[0060] In some embodiments, the upper body 1 is provided with a nut 6. The nut 6 is provided with a threaded hole. The threaded hole of the nut 6 can serve as the connecting structure 1a. Optionally, the nut 6 can include a hexagonal flange nut.

[0061] Exemplarily, the upper body 1 may include an upper body sheet metal component 11 and a nut 6 , and the nut 6 may be welded to the upper body sheet metal component 11 .

[0062] In some embodiments, the upper body 1 is provided with a plurality of connection holes. Some of the connection holes are through holes, and some of the connection holes are threaded holes. The threaded holes of the upper body 1 can be through holes or blind holes.

[0063] In some embodiments, the upper body 1 includes a front arm beam assembly 12. This embodiment of the present application can integrate the front arm beam assembly originally belonging to the lower body 2 into the upper body 1, which can simplify the structure of the lower body 2 and facilitate the installation of the battery system, drive system and other structures on the lower body 2.

[0064] In some embodiments, the front arm beam assembly 12 may include a front arm beam, a bracket, and other components (eg, standard parts) integrated on the front arm beam. The front arm beam may provide support for some components of the vehicle, such as lamps.

[0065] In some embodiments, the front arm beam assembly 12 is provided with a connection structure 1a. The front arm beam assembly 12 has high strength. Providing the connection structure 1a on the front arm beam assembly 12 can improve the connection strength and connection stability between the upper body 1 and the lower body 2.

[0066] In some embodiments, the upper body 1 includes a rear floor assembly 13. This embodiment of the present application can integrate the rear floor assembly originally belonging to the lower body 2 into the upper body 1, simplifying the structure of the lower body 2 and facilitating the installation of structures such as the battery system and the drive system on the lower body 2.

[0067] In some embodiments, the rear floor assembly 13 includes a rear floor, a seat mounting structure disposed on the rear floor, standard components disposed on the rear floor row, and other components disposed on the rear floor. The rear floor can carry seats or other components.

[0068] In some embodiments, the rear floor assembly 13 is provided with a connection structure 1a. Providing the connection structure 1a on the rear floor assembly 13 and connecting the rear floor assembly 13 to the lower body 2 can improve the connection strength and stability between the upper body 1 and the lower body 2.

[0069] In some embodiments, the upper body 1 includes a dash panel assembly 14. This embodiment of the present application can integrate the dash panel assembly 14, which originally belonged to the lower body 2, into the upper body 1, thereby simplifying the structure of the lower body 2 and facilitating the installation of structures such as the battery system and the drive system on the lower body 2.

[0070] In some embodiments, the dash panel assembly 14 includes a dash panel and other components mounted on the dash panel (e.g., standard components and brackets). The dash panel serves as an important barrier between the engine compartment and the driver's cabin. It not only absorbs and transmits energy during a collision, provides sufficient rigidity for the vehicle body frame, but also affects the sealing performance of the entire vehicle.

[0071] In some embodiments, the dash panel assembly 14 is provided with a connecting structure 1a. Providing the connecting structure 1a on the dash panel assembly 14 and connecting the dash panel assembly 14 to the lower body 2 can improve the connection strength and connection stability between the upper body 1 and the lower body 2.

[0072] In some embodiments, the upper body 1 includes a front arm beam assembly 12 , a rear floor assembly 13 , and a front wall panel assembly 14 .

[0073] In some embodiments, the lower body 2 includes a front floor 25, and the rear floor assembly 13 includes a rear floor. The front floor 25 is closer to the front of the vehicle than the rear floor. The front floor 25 is integrated with the lower body 2, and the middle of the upper body 1 is hollowed out.

[0074] In some embodiments, the front arm beam assembly 12 is disposed at the front end of the upper body 1 close to the front of the vehicle.

[0075] In some embodiments, the upper vehicle body 1 further includes a rear panel assembly 15. The front panel assembly 14 is located on a side of the rear panel assembly 15 close to the front of the vehicle.

[0076] In some embodiments, the rear panel assembly 15 includes a rear panel and other components (such as standard parts, brackets, locks, etc.) arranged on the rear panel. The rear panel is a car covering, which is the tailgate of the car trunk and one of the main load-bearing structural components at the rear of the car.

[0077] In some embodiments, the upper body 1 includes a rear floor assembly 13, a front panel assembly 14, and two first longitudinal beams 16, each of which connects the rear floor assembly 13 and the front panel assembly 14. The first longitudinal beams 16 are provided with a connecting structure 1a.

[0078] The two first longitudinal beams 16 have relatively high strength. Providing the connection structure 1 a on the first longitudinal beams 16 can improve the connection strength and connection stability between the upper vehicle body 1 and the lower vehicle body 2 .

[0079] In some embodiments, the first longitudinal beam 16 extends along the longitudinal direction X of the vehicle. Two first longitudinal beams 16 are spaced apart along the width direction Y of the vehicle. Optionally, the longitudinal direction X, the width direction Y, and the height direction Z are perpendicular to each other. For example, the longitudinal direction X is parallel to the arrangement direction of the front and rear ends of the vehicle.

[0080] In some embodiments, the first longitudinal beam 16 may be a rocker beam of the upper body 1 .

[0081] In some embodiments, the rear floor assembly 13 , the front panel assembly 14 , and the two first longitudinal beams 16 together form a support surface 10 a for clamping the sealing component 7 with the lower vehicle body 2 .

[0082] The supporting surface 10 a can stably press against the sealing component 7 to improve the airtightness and watertightness of the passenger compartment S.

[0083] In some embodiments, the support surface 10 a is annular, and the lower vehicle body 2 and the support surface 10 a clamp an annular sealing component 7 to achieve sealing of the passenger compartment S.

[0084] An embodiment of the present application further provides a vehicle, which includes an upper body 1, a lower body 2 and a connector 3 according to any of the aforementioned embodiments. The connector 3 cooperates with the connecting structure 1a to detachably connect the lower body 2 and the upper body 1.

[0085] The embodiments of the present application do not limit the type of connector 3. In some examples, the connector 3 may include a fastener. Alternatively, the fastener may include at least one of a bolt, a nut, a stud, a screw, and a pin. In other examples, the connector 3 may include a buckle.

[0086] The number of the connecting member 3 may be one or more.

[0087] In some examples, there are multiple connectors 3. The multiple connectors 3 can be made of the same component, for example, all of the multiple connectors 3 are bolts. Alternatively, the multiple connectors 3 can also be made of different components, for example, some of the connectors 3 are bolts and some of the connectors 3 are screws.

[0088] By providing the connecting piece 3, the upper body 1 and the lower body 2 are separated into two independent assemblies.

[0089] By disassembling and assembling the connecting parts 3, the upper body 1 and the lower body 2 can be separated, decoupled and connected, thereby realizing independent development of the upper body 1 and the lower body 2, so that the upper body 1 and the lower body 2 can be replaced according to needs, shortening the R&D cycle and reducing costs.

[0090] In some embodiments, there may be multiple connectors 3. The positions of the multiple connectors 3 can be set according to the connection strength requirements of the upper body 1 and the lower body 2.

[0091] In some embodiments, the connection member 3 comprises a bolt.

[0092] Exemplarily, there are multiple connecting members 3, and at least some of the multiple connecting members 3 are bolts.

[0093] The bolts can be threadedly connected to the upper vehicle body 1 or to the lower vehicle body 2 .

[0094] The bolts are highly standardized and easy to replace. The bolt connection method is easy to disassemble and assemble, which helps to improve the assembly efficiency of the upper body 1 and the lower body 2.

[0095] Compared with the upper body 1 and the lower body 2 connected by welding, rotary tapping riveting (FD), self-piercing riveting (PR), bonding and other processes, the upper body 1 and the lower body 2 are connected by bolts, which can achieve the decoupling of the physical structures of the upper body 1 and the lower body 2.

[0096] In some embodiments, the vehicle further includes a sealing component 7 , which is sandwiched between the upper vehicle body 1 and the lower vehicle body 2 . Exemplarily, the supporting surface 10 a and the lower vehicle body 2 sandwich the sealing component 7 .

[0097] The embodiment of the present application does not limit the manner in which the sealing component 7 achieves sealing. For example, the sealing component 7 may achieve sealing through compression deformation. Alternatively, the sealing component 7 may also achieve sealing through bonding or other methods.

[0098] The embodiment of the present application does not limit the material of the sealing component 7. For example, the sealing component 7 can be made of an elastic and compressible material, such as rubber, foam, etc. Alternatively, the sealing component 7 can also be made of a solidified colloid.

[0099] The sealing component 7 can achieve sealing between the upper body 1 and the lower body 2, reduce impurities entering the passenger compartment S, improve passenger experience, and enhance vehicle reliability.

[0100] In some embodiments, the sealing component 7 may have the advantages of being dustproof, waterproof, soundproof, wear-resistant, and easy to maintain.

[0101] In some embodiments, the sealing member 7 surrounds the passenger compartment S of the vehicle.

[0102] The passenger compartment S may be a space for passengers to sit in, which is formed by the upper vehicle body 1 and the lower vehicle body 2. For example, the passenger compartment S may be provided with seats, armrests and other components.

[0103] The annular sealing component 7 can increase the sealing area, separate the passenger compartment S from the external environment, reduce external impurities entering the passenger compartment S through the space between the upper body 1 and the lower body 2, improve passenger experience, and enhance vehicle reliability.

[0104] In some embodiments, the sealing member 7 is bonded to the lower body 2. In some examples, glue may be applied to the lower body 2 and then the sealing member 7 may be bonded to the lower body 2; in alternative examples, the sealing member 7 may include adhesive backing and may be directly bonded to the lower body 2.

[0105] The embodiment of the present application can reduce the offset of the sealing component 7 and the misalignment of the sealing component 7 when disassembling and assembling the upper body 1 and the lower body 2, thereby improving assembly efficiency; in addition, the sealing component 7 is bonded to the lower body 2, which can also improve the sealing performance.

[0106] In some embodiments, the material of the sealing component 7 includes EPDM (Ethylene Propylene Diene Monomer).

[0107] EPDM rubber has strong rebound force and good sealing performance.

[0108] In some embodiments, the vehicle further includes a vehicle interior, a human-computer interaction system, and an entertainment system installed on the upper body 1 .

[0109] In some embodiments, the vehicle includes a chassis 4 , which includes a lower body 2 and a battery cell 8 , and the battery cell 8 is mounted on the lower body 2 .

[0110] The battery cell 8 is the smallest unit that can independently realize charging and discharging. The battery cell 8 may include a lithium-ion secondary battery cell, a lithium-sulfur battery cell, a sodium-lithium-ion battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell, etc., and the embodiments of the present application do not limit this. The battery cell 8 may be cylindrical, flat, rectangular, or other shapes, etc., and the embodiments of the present application do not limit this. The battery cell 8 is generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft-pack battery cells, and the embodiments of the present application do not limit this.

[0111] In this embodiment, battery cells 8 are mounted on the lower body 2, allowing the lower body 2 to also function as a battery housing. This reduces some of the redundant structure of traditional batteries, improves vehicle range, and reduces weight and costs. The battery cells 8 are integrated into the chassis 4, achieving CTC (cell to chassis) integration.

[0112] In some embodiments, the chassis 4 may further include a drive system and a chassis system, wherein the chassis system includes a transmission system, a travel system, a steering system, and a braking system. The drive system may include a motor.

[0113] The embodiment of the present application integrates the battery system, drive system and chassis system together, reducing the number of components, saving space, improving structural efficiency, and significantly reducing vehicle weight and increasing battery life.

[0114] The chassis 4 of the present embodiment is highly adaptable, offering improved compatibility with the vehicle and enabling rapid and flexible mass production. Its high degree of integration and modularity allows for cross-platform adaptation to future vehicle models of all levels and types. Furthermore, this high degree of integration and modularity simplifies the number of parts and production steps, reducing costs while increasing battery capacity and range.

[0115] By setting up an independent upper body 1 and lower body 2, the complete chassis system, battery system and drive system can be integrated on the lower body 2, and the entire vehicle interior, human-computer interaction system and entertainment system can be integrated on the upper body 1, so that the entire chassis 4 can be designed and operated independently of the upper body 1, and the vehicle drive part and passenger compartment S can be independently developed and assembled.

The reinforcement plate and standard components may be mounted on the front longitudinal beam. Optionally, the standard components may include bolts or studs. The front longitudinal beam can collapse and absorb energy in the event of a severe collision, thereby protecting the lives of passengers in the vehicle.

[0122] In some embodiments, the lower vehicle body 2 further includes a front anti-collision beam 292 , which is connected to the front longitudinal beam assembly 291 .

[0123] For example, the front anti-collision beam 292 may be detachably connected to the front longitudinal beam assembly 291 or may be non-detachably connected.

[0124] In some embodiments, the front anti-collision beam 292 is detachably connected to the front longitudinal beam assembly 291. Alternatively, the front anti-collision beam 292 is connected to the front longitudinal beam assembly 291 by bolts.
