Description

Technical Field

[0001] This application belongs to the field of vehicle technology, and in particular relates to a chassis and a vehicle. Background Technology

[0002] In current chassis, there are sharp or right-angled structures on the chassis edges. During the sealing process, it is difficult for sealant, sealing foam, and other structures to fully adhere to these sharp or right-angled structures, making it difficult to guarantee the sealing effect. Utility Model Content

[0003] In view of the above problems, this application provides a chassis and vehicle that can alleviate the problem of poor sealing effect of the chassis at acute or right-angle structures.

[0004] In a first aspect, some embodiments of this application provide a chassis, including:

[0005] A first structural segment, on which a battery device is provided; the first structural segment has a first surface, a second surface, and a connecting surface connecting the first surface and the second surface, the first surface and the second surface being spaced apart in the height direction of the first structural segment; a first support member, connected to the first structural segment, the first support member having a third surface, one end of the third surface being connected to the first surface, and the included angle between the third surface and the first surface being greater than the included angle between the connecting surface and the first surface; the other end of the third surface being connected to the second surface, and the included angle between the third surface and the second surface being greater than the included angle between the connecting surface and the second surface; a sealing structure, connected to the first surface, the second surface, and the third surface.

[0006] In the technical solution of this embodiment, a first support member is provided on the first structural segment. The angle change at the intersection of the first surface and the third surface, and the second surface and the third surface is relatively gentle, which makes it easy for the sealing structure to be pasted on the first surface, the second surface and the third surface. It also makes the sealing structure more stably bonded to the intersection of the first surface and the third surface, and the second surface and the third surface, thereby improving the sealing effect of the sealing structure and reducing the bonding difficulty of the sealing structure.

[0007] In some embodiments, the first structural segment includes at least two first beams spaced apart along a first direction, each first beam having a first surface; the first structural segment also includes at least two second beams connected to the first beams, the second beams extending along the first direction, and the at least two second beams spaced apart along a second direction perpendicular to the first direction, each second beam having a second surface; the first beam or the second beam has a connecting surface; and a first support member is connected to the first beam and the second beam.

[0008] The technical solution of this embodiment provides some specific structures of the first structural segment. The first support is set at the connection between the first beam and the second beam so that the connection between the third surface and the second surface, and between the third surface and the first surface is relatively smooth. This facilitates the connection of the sealing structure to the first beam and the second beam, and also enables the sealing structure to be more stably connected to the connection part of the first beam and the second beam. This improves the connection stability and sealing effect of the sealing structure and reduces the bonding difficulty of the sealing structure.

[0009] In some embodiments, the second beam has an inclined surface that is inclined relative to the second surface, the first support member is a plate-like structure and is connected to the inclined surface, one end of the first support member is connected to the first surface, and the other end of the first support member is connected to the second surface.

[0010] The technical solution of this embodiment provides some specific structures of the second beam, with an inclined surface provided on the second beam and the first support member connected to the inclined surface, so that the sealing structure can be more stably connected to the connection part of the first beam and the second beam.

[0011] In some embodiments, the first support is sealed to the first beam; and / or the first support is sealed to the second beam.

[0013] In some embodiments, the battery device includes a housing and battery cells housed within the housing, with a first beam and / or a second beam forming part of the housing structure.

[0014] In the technical solution of this embodiment, a portion of the battery pack housing is used as a first beam and / or a second beam to save space on the first beam and / or the second beam, thereby increasing the space occupied by the battery pack. This facilitates the installation of a larger capacity battery pack on the chassis and improves the vehicle's range.

[0015] In some embodiments, the chassis further includes a second structural segment detachably connected to the first structural segment, and a sealing structure is also connected to the second structural segment to fill at least a portion of the gap between the second structural segment and the first structural segment.

[0016] In this embodiment, the chassis includes a second structural segment, and the second structural segment is detachably connected to the first structural segment to facilitate the replacement, maintenance, and installation of the first structural segment and the battery device; a sealing structure is provided between the first structural segment and the second structural segment to seal at least part of the gap between the first structural segment and the second structural segment, thereby improving the sealing effect of the connection between the first structural segment and the second structural segment.

[0017] In some embodiments, a second support member is connected to the second structural segment, the second support member has a fourth surface, the second support member is connected to the first support member, and the fourth surface is connected to the third surface; a sealing structure is also connected to the fourth surface, and a portion of the sealing structure is located between the third surface and the fourth surface.

[0018] The technical solution of this embodiment provides some specific structures of the second structural segment, sets up a second support member, and makes the second support member correspond to the first support member, so that the second structural segment can better correspond to and connect with the first structural segment, and also makes the sealing structure better seal the gap between the connection part of the second structural segment and the first structural segment, thereby improving the sealing performance.

[0019] In some embodiments, the second structural segment includes a third beam and a fourth beam connected to the third beam. The third beam has a fifth surface on the side facing the first structural segment, and the fifth surface is connected to the first surface. The fourth beam has a sixth surface on the side facing the first structural segment, and the sixth surface is connected to the second surface. A second support member is connected to the third beam and the fourth beam, and both ends of the second support member are connected to the fifth surface and the sixth surface, respectively. A sealing structure is also connected to the fifth surface and the sixth surface, with a portion of the sealing structure located between the first surface and the fifth surface, and a portion of the sealing structure located between the second surface and the sixth surface.

[0020] The technical solution of this embodiment provides some specific structures for the second structural segment. The second support member is set at the connection between the third beam and the fourth beam, and the fourth surface and the fifth surface, as well as the fourth surface and the sixth surface, are all set at obtuse angles. This facilitates the connection of the sealing structure to the third beam and the fourth beam, and also enables the sealing structure to be more stably connected to the connection between the third beam and the fourth beam. As a result, the sealing structure can better seal the gap between the connection between the second structural segment and the first structural segment, thereby improving the sealing performance.

[0021] In some embodiments, the second support is sealed to the third beam; and / or the second support is sealed to the fourth beam.

[0022] In the technical solution of this embodiment, the second support member is sealed to the third beam and / or the fourth beam to improve the sealing performance of the connection between the second support member and the third beam, and between the second support member and the fourth beam, thereby improving the sealing performance of the entire chassis.

[0023] In some embodiments, there are two second structural segments, and the two second structural segments are respectively connected to opposite sides of the first structural segment.

[0024] In the technical solution of this embodiment, the chassis has a three-section structure and two second structural sections, so that the two second structural sections can be used to support the electric drive system, the electronic control system, the steering system, the suspension system or other systems respectively.

[0025] In some embodiments, the length direction of the first support member is parallel to the length direction of the second beam; or the length direction of the first support member is perpendicular to the length direction of the second beam.

[0026] The technical solution of this embodiment provides some positional relationships between the first support member and the second beam, so that the first support member can have different installation positions and can adapt to different structures.

[0027] In some embodiments, the sealing structure includes foam or putty.

[0028] The technical solution of this embodiment provides some specific structures for sealing structures, so that the sealing structure can be connected to the first structural segment and the sealing structure can be easily disassembled and replaced.

[0059] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0060] During chassis manufacturing, sealing structures are typically required at the joints between different components of the frame to prevent external impurities (gravel, water, etc.) from entering the chassis interior or passenger compartment through gaps in the joints. Currently, chassis joints often feature sharp or right angles. At these joints, sealant, sealing foam, and other sealing materials struggle to adhere perfectly to the corresponding structures at the corners, and the sealants are prone to detachment, resulting in poor sealing performance.

[0061] For example, at the connection between the crossbeam and the longitudinal beam of the frame, the upper surface of the crossbeam and the side of the longitudinal beam form a right angle structure; at this time, it is difficult to completely adhere the two surfaces at the intersection using sealant or sealing foam.

[0062] To improve the sealing effect at the connection structure, one current solution involves setting different sealing structures on the two sides of the right-angle structure. For example, at the connection between the crossbeam and longitudinal beam of the chassis, sealing foam is placed on the upper surface of the crossbeam, while sealant is placed on the side of the longitudinal beam. At the connection between the crossbeam and longitudinal beam, the sealant and the sealing foam interfere with each other to achieve a "handshake" effect. However, this solution has a complex manufacturing process, and removing the sealing structure during chassis inspection and maintenance is difficult, as is reinstalling it.

[0063] Based on the above considerations, in order to alleviate the problem of poor sealing effect of the chassis at acute or right angle structures, this application provides a chassis in which a first support member is provided on the first structural section of the chassis, so that the included angle between the third surface and the first surface is greater than the included angle between the connecting surface and the first surface, and the included angle between the third surface and the second surface is greater than the included angle between the connecting surface and the second surface, so that the connection between the first surface and the third surface, and the second surface and the third surface is smoother.

[0064] In such a chassis, the angle changes at the intersections of the first and third surfaces, and the second and third surfaces are relatively gentle, which makes it easier to attach the sealing structure to the first, second, and third surfaces. This allows the sealing structure to be more stably bonded to the intersections of the first and third surfaces, and the second and third surfaces, thereby improving the sealing effect of the sealing structure and reducing the difficulty of bonding the sealing structure.

[0065] The chassis disclosed in this application can be applied to vehicles, which can refer to large cars, small cars, special-purpose vehicles, etc. For example, according to the power source, the vehicle can be a pure electric vehicle, a gasoline vehicle, an electric-gasoline hybrid vehicle, etc.; according to the vehicle type, the car can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0066] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0067] refer to Figure 1 Vehicle 1000 comprises an upper body 200 and a chassis 100. The upper body 200 refers to the superstructure of vehicle 1000, primarily comprising the passenger compartment, body panels, and interior trim, responsible for providing a safe and comfortable space for occupants and shaping the exterior appearance of vehicle 1000. The chassis 100 refers to the lower structure of vehicle 1000, containing mechanical components related to driving, handling, and power transmission. The chassis 100 serves as the basic load-bearing platform for vehicle 1000, directly affecting its dynamic performance and reliability.

[0068] In a monocoque chassis, the upper body 200 and the chassis 100 are integrally machined to jointly bear the load of the vehicle 1000; in a non-monocoque chassis, the upper body 200 is independently mounted on the chassis.

[0069] Firstly, reference Figures 2 to 8This application provides a chassis 100, including a first structural segment 20, a first support member 30, and a sealing structure. The first structural segment 20 is equipped with a battery device 50. The first structural segment 20 has a first surface 211, a second surface 221, and a connecting surface connecting the first surface 211 and the second surface 221. The first surface 211 and the second surface 221 are spaced apart along the height direction of the first structural segment 20. The first support member 30 is connected to the first structural segment 20 and has a third surface 301. One end of the third surface 301 is connected to the first surface 211, and the angle between the third surface 301 and the first surface 211 is greater than the angle between the connecting surface and the first surface 211. The other end of the third surface 301 is connected to the second surface 221, and the angle between the third surface 301 and the second surface 221 is greater than the angle between the connecting surface and the second surface 221. The sealing structure is connected to the first surface 211, the second surface 221, and the third surface 301.

[0070] In the diagram, the X-axis represents the length of chassis 100, the Y-axis represents the width of chassis 100, and the Z-axis represents the height of chassis 100.

[0071] The first structural segment 20 is part of the structure of the chassis 100. The first structural segment 20 can be part of the main frame of the chassis 100, and the sealing structure can be located at the connection between the first structural segment 20 and other structures of the main frame. The first structural segment 20 can also be a bracket structure on the chassis 100 for supporting the battery device 50. In this case, the bracket structure can be connected to the chassis 100, and the sealing structure can be located at the connection between the bracket structure and the chassis 100.

[0072] A battery device 50 is provided on the first structural section 20. At this time, the first structural section 20 can be the energy storage section of the chassis 100. The chassis 100 can also include a front compartment section and / or a rear compartment section. The front compartment section can be used to arrange the electric drive system, electronic control system, steering system, suspension system, etc., and the rear compartment section can be used to arrange the rear-drive electric drive system, suspension system, etc.

[0073] The first surface 211 refers to a surface on the first structural segment 20. When the first structural segment 20 is connected to other structures, the first surface 211 is the surface on the first structural segment 20 facing the other structures. For example, when the first structural segment 20 is connected to the front compartment segment, the first surface 211 can be the surface on the first structural segment 20 facing the front compartment segment.

[0074] The second surface 221 refers to a surface on the first structural segment 20. When the first structural segment 20 is connected to other structures, the second surface 221 can be another surface on the first structural segment 20 facing other structures. Since the first structural segment 20 is usually a structure with an uneven surface, the first surface 211 and the second surface 221 are spaced apart in the height direction of the first structural segment 20, that is, the first surface 211 and the second surface 221 are at different heights. The second surface 221 can be parallel to the first surface 211 or it can be set at an angle to the first surface 211.

[0075] The connecting surface refers to the surface that is connected to the first surface 211 and the second surface 221. For example, the included angles between the connecting surface and the first surface 211 and between the connecting surface and the second surface 221 are both small, which can easily lead to poor adhesion performance of the sealing structure at the connection points between the connecting surface and the first surface 211 and between the connecting surface and the second surface 221.

[0076] The battery device 50 refers to the structure in the chassis 100 used to provide electrical energy. The battery device 50 may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include multiple battery cells 52, which are connected in series, parallel, or mixed connection via a busbar. The battery device 50 is connected to the first structural section 20 by means of screwing, welding, snap-fitting, or other methods, in which case the first structural section 20 can serve as an energy storage section.

[0077] The first support member 30 refers to the structure on the chassis 100 used to support the sealing structure. The first support member 30 can be a prismatic structure, a cylindrical structure, or a structure of other shapes. The number of first support members 30 can be one or more. The first support member 30 is connected to the first structural segment 20. The first support member 30 can be connected to the first structural segment 20 by welding, bonding, or other means. The material of the first support member 30 can include metal, plastic, or other materials.

[0078] The third surface 301 refers to the surface on the first support member 30. When the first structural segment 20 is connected to other structures, the third surface 301 can be the surface of the first support member 30 facing other structures. When the first support member 30 is connected to the first structural segment 20, one end of the third surface 301 is connected to the first surface 211, and the other end of the third surface 301 is connected to the second surface 221. At this time, the sealing structure can be bonded to the first surface 211, the second surface 221, and the third surface 301.

[0079] The angle between the third surface 301 and the first surface 211 is greater than the angle between the connecting surface and the first surface 211. In other words, the connection between the third surface 301 and the first surface 211 is gentler than the connection between the connecting surface and the first surface 211. This reduces the difficulty of bonding the sealing structure and lowers the risk of detachment. For example, the angle between the connecting surface and the first surface 211 can be 90°, in which case the angle between the third surface 301 and the first surface 211 can be greater than 90°.

[0080] The angle between the third surface 301 and the second surface 221 is greater than the angle between the connecting surface and the second surface 221. In other words, the connection between the third surface 301 and the second surface 221 is gentler than the connection between the connecting surface and the second surface 221. This reduces the difficulty of bonding the sealing structure and lowers the risk of detachment. For example, the angle between the connecting surface and the second surface 221 can be 90°, in which case the angle between the third surface 301 and the second surface 221 can be greater than 90°.

[0081] The sealing structure refers to the structure in the chassis 100 used to seal the gap between the first structural section 20 and other connected structures. Depending on the specific structure and function of the first structural section 20, the other structures connected to the first structural section 20 can be other structures of the frame or structures on the upper body 200.

[0082] The sealing structure may include foam, sealant, putty or other sealing structures; when the first structural segment 20 is connected to other structures, the sealing structure is located between the first structural segment 20 and other structures to seal the gap between the first structural segment 20 and other structures, reducing the risk of external debris (such as gravel, dust, water, etc.) entering the chassis 100 or the crew compartment.

[0083] The sealing structure is connected to the first surface 211, the second surface 221 and the third surface 301. Different parts of the sealing structure are connected to the first surface 211, the second surface 221 and the third surface 301 respectively to seal the gaps corresponding to the first surface 211, the second surface 221 and the third surface 301.

[0084] When the sealing structure is bonded to the first surface 211, the connecting surface, and the second surface 221, the bending angle of the sealing structure at the intersection of the connecting surface and the first surface 211 and the intersection of the connecting surface and the second surface 221 is relatively large. It is difficult for the sealing structure to fully fit with the first surface 211, the second surface 221, and the connecting surface, resulting in a poor sealing effect.

[0085] Accordingly, a first support member 30 is provided so that the sealing structure is connected to the first surface 211, the second surface 221 and the third surface 301, and the connection between the first surface 211 and the third surface 301 and the connection between the second surface 221 and the third surface 301 is smoother, which reduces the difficulty of bonding the sealing structure, reduces the risk of the sealing structure detaching and improves the sealing effect.

[0086] In this embodiment, a first support member 30 is provided on the first structural segment 20. The angle change at the intersection of the first surface 211 and the third surface 301, and the second surface 221 and the third surface 301 is relatively gentle, which makes it easy for the sealing structure to be pasted on the first surface 211, the second surface 221 and the third surface 301. It also makes the sealing structure more stably bonded to the intersection of the first surface 211 and the third surface 301, and the second surface 221 and the third surface 301, thereby improving the sealing effect of the sealing structure and reducing the bonding difficulty of the sealing structure.

[0087] refer to Figures 3 to 6 In some embodiments, the first structural segment 20 includes at least two first beams 21 spaced apart along a first direction, each first beam 21 having a first surface 211; the first structural segment 20 also includes at least two second beams 22 connected to the first beams 21, each second beam 22 extending along the first direction, and at least two second beams 22 spaced apart along a second direction perpendicular to the first direction, each second beam 22 having a second surface 221; the first beam 21 or the second beam 22 has a connecting surface; and the first support member 30 is connected to the first beam 21 and the second beam 22.

[0088] The first beam 21 refers to the beam structure in the first structural segment 20. The first beam 21 is a supporting structure in the first structural segment 20, providing support and installation foundation for other structures installed on the first structural segment 20. For example, the first beam 21 can be the crossbeam of the chassis 100.

[0089] The first beam 21 can be a box girder structure, an I-beam structure, or a beam structure of other shapes; the number of first beams 21 is at least two, and the number of first beams 21 can be two, three, or more; the material of the first beam 21 can include metal, plastic, or other materials.

[0090] The number of first beams 21 is at least two, and can be two, three or more. At least two first beams 21 are arranged at intervals along a first direction. The length direction of the first beams 21 can be perpendicular to the first direction or at an angle to it. In this case, the battery device 50 can be positioned between two adjacent first beams 21. The first direction can be the length direction X of the chassis 100 or the width direction Y of the chassis 100; for example, the first direction is the length direction X of the chassis 100.

[0091] The first beam 21 has a first surface 211, that is, the first surface 211 is the surface on the first beam 21. When the first structural member 20 is connected to other structures, the first surface 211 is the surface of the first beam 21 facing the other structures. The first surface 211 is the surface on the first beam 21 that carries the sealing structure. The sealing structure is at least partially connected to the first beam 21. The sealing structure can completely cover the first surface 211 or only cover a part of the first surface 211.

[0092] The second beam 22 refers to another beam structure in the first structural segment 20. The second beam 22 is also a supporting structure in the first structural segment 20, providing support and installation foundation for other structures installed on the first structural segment 20. For example, the second beam 22 can be a longitudinal beam of the chassis 100 or a sill beam of the chassis 100.

[0093] The second beam 22 can be a box girder structure, an I-beam structure, or a beam structure of other shapes; the material of the second beam 22 can include metal, plastic, or other materials; the second beam 22 extends along the first direction, that is, the length direction of the second beam 22 is parallel to the first direction; the number of second beams 22 is at least two, and the number of second beams 22 can be two, three, or more, with at least two second beams 22 arranged at intervals along the second direction, in which case the battery device 50 can be disposed between two adjacent second beams 22.

[0094] The second direction is perpendicular to the first direction. The second direction can be either the length direction X of the chassis 100 or the width direction Y of the chassis 100. For example, the first direction is the length direction X of the chassis 100, and the second direction is the width direction Y of the chassis 100.

[0095] For example, there are two first beams 21 and two second beams 22. The length direction of the first beam 21 is parallel to the width direction Y of the chassis 100, and the two first beams 21 are arranged at intervals along the length direction X of the chassis 100. The length direction of the second beam 22 is parallel to the length direction X of the chassis 100, and the two second beams 22 are arranged at intervals along the width direction Y of the chassis 100. The two second beams 22 are respectively connected to the two first beams 21 on both sides along the width direction Y of the chassis 100. At this time, the two first beams 21 and the two second beams 22 form an internal space to accommodate the battery device 50.

[0096] The second beam 22 has a second surface 221, which is a surface on the second beam 22. Since the second surface 221 and the first surface 211 are spaced apart in the height direction of the first structural segment 20, and a connecting surface connects the first surface 211 and the second surface 221, the connecting surface can be a surface on the first beam 21 or a surface on the second beam 22. For example, the second surface 221 is above the first surface 211, and the connecting surface is a surface on the second beam 22.

[0097] The first support member 30 is connected to the first beam 21 and the second beam 22, that is, the first support member 30 is located at the connection between the first beam 21 and the second beam 22; the first support member 30 can be connected to the first beam 21 by welding, screwing or other means, and the first support member 30 can also be connected to the second beam 22 by welding, screwing or other means.

[0098] When the first support 30 is connected to the first beam 21 and the second beam 22, one end of the third surface 301 is connected to the first surface 211, and the other end of the third surface 301 is connected to the second surface 221. The connection between the first surface 211 and the third surface 301, and the connection between the second surface 221 and the third surface 301, are relatively flat to facilitate the installation of the sealing structure.

[0099] When the first support member 30 is connected to the first beam 21 and the second beam 22, the first support member 30 may have other surfaces besides the third surface 301; wherein, one other surface of the first support member 30 may be connected to the first surface 211, and another other surface of the first support member 30 may be connected to the connecting surface, and the first support member 30 may be a triangular prism structure.

[0100] This embodiment provides some specific structures of the first structural segment 20. The first support member 30 is set at the connection between the first beam 21 and the second beam 22, so that the connection between the third surface 301 and the second surface 221, and between the third surface 301 and the first surface 211 is relatively smooth. This facilitates the connection of the sealing structure to the first beam 21 and the second beam 22, and also enables the sealing structure to be more stably connected to the connection part of the first beam 21 and the second beam 22, thereby improving the connection stability and sealing effect of the sealing structure and reducing the bonding difficulty of the sealing structure.

[0101] refer to Figures 3 to 6 In some embodiments, the second beam 22 is provided with an inclined surface 222 that is inclined relative to the second surface 221. The first support member 30 is a plate-shaped structure and is connected to the inclined surface 222. One end of the first support member 30 is connected to the first surface 211, and the other end of the first support member 30 is connected to the second surface 221.

[0102] Inclined surface 222 refers to the surface on the second beam 22, which is inclined relative to the second surface 221. Depending on the relative position of the first beam 21 and the second beam 22, the inclined surface 222 can be inclined from the second surface 221 toward the direction where the first surface 211 is located. The inclined surface 222 can be formed by cutting the second beam 22, or by connecting wedge-shaped pieces, trapezoidal pieces or other structural pieces to the second beam 22.

[0103] The first support member 30 is a plate-shaped structure and is connected to the inclined surface 222. Since one end of the third surface 301 is connected to the first surface 211 and the other end is connected to the second surface 221, the first support member 30 can be a plate-shaped structure with a uniform thickness according to the inclination direction of the inclined surface 222. At this time, the third surface 301 is parallel to the inclined surface 222. The first support member 30 can also be a plate-shaped structure with a non-uniform thickness so that both ends of the third surface 301 can be connected to the first surface 211 and the second surface 221.

[0104] For example, when the second beam 22 is a box girder, its interior is a hollow structure. When the inclined surface 222 is formed by cutting the second beam 22, it is a hollow annular surface. In this case, the area on the inclined surface 222 that can contact the sealing structure is small, which can easily lead to unstable sealing structure connections. Therefore, a first support member 30 is provided on the inclined surface 222 to increase the connection area of ​​the sealing structure and improve its connection stability.

[0105] This embodiment provides some specific structures of the second beam 22. An inclined surface 222 is provided on the second beam 22, and the first support member 30 is connected to the inclined surface 222, so that the sealing structure can be more stably connected to the connection part of the first beam 21 and the second beam 22.

[0106] In some embodiments, the first support member 30 is sealed to the first beam 21; and / or the first support member 30 is sealed to the second beam 22.

[0107] The first support member 30 is sealed to the first beam 21. The first support member 30 can be sealed to the first beam 21 by welding, sealing bonding or other means. The first support member 30 is sealed to the second beam 22. The first support member 30 can also be sealed to the second beam 22 by welding, sealing bonding or other means.

[0108] Because the sealing structure connects the first surface 211, the second surface 221, and the third surface 301, it is difficult for the sealing structure to cover the connection points between the first support member 30 and the first beam 21, and between the first support member 30 and the second beam 22. Therefore, the first support member 30 is sealed to the first beam 21 and / or the second beam 22 to improve the overall sealing performance of the chassis 100 and reduce the risk of external impurities (such as gravel, dust, water, etc.) entering the interior of the chassis 100 or the passenger compartment.

[0109] In this embodiment, the first support member 30 is sealed to the first beam 21 and / or the second beam 22 to improve the sealing performance of the connection between the first support member 30 and the first beam 21, and between the first support member 30 and the second beam 22, thereby improving the sealing performance of the entire chassis 100.

[0110] refer to Figure 11 In some embodiments, the battery device 50 includes a housing 51 and battery cells 52 housed within the housing 51, with a first beam 21 and / or a second beam 22 forming part of the structure of the housing 51.

[0111] The housing 51 refers to the structure in the battery device 50 that provides a mounting base for other structures, such as the battery cell 52. The housing 51 can be a prismatic, cylindrical, or other shaped structure. The material of the housing 51 can include metal, plastic, or other materials.

[0112] The housing 51 can adopt various structures. For example, the housing 51 may include a first part and a second part, which overlap each other and together define a receiving space for accommodating the battery cell 52; the second part may be a hollow structure with one end open, and the first part may be a plate-like structure, with the first part covering the open side of the second part so that the first part and the second part together define the receiving space; the first part and the second part may also be hollow structures with one side open, with the open side of the first part covering the open side of the second part.

[0113] A battery cell 52 refers to the smallest unit that makes up the battery device 50. There can be one, two, or more battery cells 52. When there are multiple battery cells 52, they can be connected in series, in parallel, or in a mixed configuration. A mixed configuration means that multiple battery cells 52 are connected in both series and parallel. Multiple battery cells 52 can be directly connected in series, in parallel, or in a mixed configuration and then housed in the housing 51. Alternatively, multiple battery cells 52 can first be connected in series, in parallel, or in a mixed configuration to form a battery module, and then multiple battery modules can be connected in series, in parallel, or in a mixed configuration to form a whole and housed in the housing 51.

[0114] The first beam 21 can be part of the structure of the housing 51. In this case, the first beam 21 can serve as part of the structure of the battery device 50, providing an installation foundation and support protection for the battery cells 52. The first beam 21 can also serve as part of the structure of the chassis 100, providing support for the chassis 100. Compared to the independent structures of the chassis 100 and the battery device 50, the first beam 21 can simultaneously serve as part of both the housing 51 and the chassis 100. In other words, a part of the housing 51 can directly serve as a structural component of the chassis 100, improving the structural efficiency of the housing 51 and saving some structural space occupied by the chassis 100, thereby allowing the battery device 50 to have a larger installation space.

[0115] Similar to the first beam 21, the second beam 22 can also be part of the structure of the housing 51. In this case, the second beam 22 can serve as part of the battery device 50, providing an installation foundation and support for the battery cells 52. The second beam 22 can also serve as part of the chassis 100, providing support for the chassis 100. Compared to the independent structures of the chassis 100 and the battery device 50, allowing the second beam 22 to simultaneously function as part of both the housing 51 and the chassis 100—meaning a part of the housing 51 directly becomes part of the chassis 100's structural components—improves the structural efficiency of the housing 51, saves space occupied by parts of the chassis 100's structure, and thus allows the battery device 50 to have a larger installation space.

[0116] In this embodiment, a portion of the structure of the housing 51 of the battery device 50 is used as the first beam 21 and / or the second beam 22 to save the first beam 21 and / or the second beam 22, and to increase the space occupied by the battery device 50, thereby facilitating the installation of a larger capacity battery device 50 on the chassis 100 and improving the range of the vehicle 1000.

[0117] refer to Figure 2 In some embodiments, the chassis 100 further includes a second structural segment 10 detachably connected to the first structural segment 20, and a sealing structure is also connected to the second structural segment 10 to fill at least a portion of the gap between the second structural segment 10 and the first structural segment 20.

[0118] The second structural section 10 is a part of the structure of the chassis 100; wherein the second structural section 10 can be a part of the main frame of the chassis 100, and the first structural section 20 can be a part of the main frame of the chassis 100. The second structural section 10 is connected to the first structural section 20 and forms the main frame.

[0119] The second structural section 10 is detachably connected to the first structural section 20. The second structural section 10 can be detachably connected to the first structural section 20 by screwing, riveting, snapping or other means. This arrangement facilitates the installation, disassembly and maintenance of the second structural section 10 and the first structural section 20.

[0120] When the second structural segment 10 is connected to the first structural segment 20, the first surface 211, the second surface 221 and the third surface 301 are respectively connected to different positions of the second structural segment 10.

[0121] When the second structural segment 10 is detachably connected to the first structural segment 20, the sealing structure is located at the connection between the first structural segment 20 and the second structural segment 10 and fills at least part of the gap between the first structural segment 20 and the second structural segment 10 to achieve a sealing effect; the sealing structure can completely fill the gap between the first structural segment 20 and the second structural segment 10 to achieve a sealing effect, or it can only partially fill the gap between the first structural segment 20 and the second structural segment 10 to specifically seal part of the structure.

[0122] In this embodiment, the chassis 100 includes a second structural segment 10, and the second structural segment 10 is detachably connected to the first structural segment 20 to facilitate the replacement, maintenance, and installation of the first structural segment 20 and the battery device 50; a sealing structure is provided between the first structural segment 20 and the second structural segment 10 to seal at least part of the gap between the first structural segment 20 and the second structural segment 10, thereby improving the sealing effect of the connection between the first structural segment 20 and the second structural segment 10.

[0123] refer to Figures 7 to 10 In some embodiments, a second support member 40 is connected to the second structural segment 10. The second support member 40 has a fourth surface 401. The second support member 40 is connected to the first support member 30, and the fourth surface 401 is connected to the third surface 301. A sealing structure is connected to the fourth surface 401, and a portion of the sealing structure is located between the third surface 301 and the fourth surface 401.

[0124] The second support member 40 refers to a structure on the chassis 100 used to cooperate with the first support member 30 and press against the sealing structure. When the second structural segment 10 is connected to the first structural segment 20 and the sealing structure is located between the second structural segment 10 and the first structural segment 20, the second support member 40 can be pressed against the sealing structure. The second support member 40 can be a prismatic structure, a cylindrical structure, or other shapes. The number of second support members 40 can be one or more. The second support member 40 is connected to the first structural segment 20 by welding, bonding, or other means. The material of the second support member 40 can include metal, plastic, or other materials.

[0125] The fourth surface 401 refers to the surface on the second support member 40. The fourth surface 401 can be the surface of the second support member 40 facing the first structural segment 20. The fourth surface 401 corresponds to the third surface 301 and is parallel to the third surface 301. When the second structural segment 10 is connected to the first structural segment 20, the fourth surface 401 corresponds to the third surface 301. The sealing structure is located between the fourth surface 401 and the third surface 301, and the two sides of the sealing structure are respectively connected to the fourth surface 401 and the third surface 301 to seal the gap between the fourth surface 401 and the third surface 301.

[0126] When the second structural segment 10 is connected to the first structural segment 20 and the sealing structure is located between the second structural segment 10 and the first structural segment 20, the second support member 40 is connected to the first support member 30, and the fourth surface 401 is connected to the third surface 301. At this time, the fourth surface 401 can be connected to the third surface 301 through the sealing structure, and the gap between the fourth surface 401 and the third surface 301 is sealed by the sealing structure.

[0127] When the second structural segment 10 is connected to the first structural segment 20, the second support member 40 can better press the sealing structure against the first support member 30. At this time, the sealing structure can better fit the first surface 211, the third surface 301 and the connection between them, and the sealing structure can also better fit the corresponding part of the second structural segment 10, thereby improving the sealing effect of the sealing structure.

[0128] This embodiment provides some specific structures of the second structural segment 10, and sets up a second support member 40, which corresponds to the first support member 30, so that the second structural segment 10 can better correspond to and connect with the first structural segment 20, and also so that the sealing structure can better seal the gap between the second structural segment 10 and the first structural segment 20, thereby improving the sealing performance.

[0129] refer to Figures 7 to 10 In some embodiments, the second structural segment 10 includes a third beam 11 and a fourth beam 12 connected to the third beam 11. The third beam 11 has a fifth surface 111 on the side facing the first structural segment 20, and the fifth surface 111 is connected to the first surface 211. The fourth beam 12 has a sixth surface 121 on the side facing the first structural segment 20, and the sixth surface 121 is connected to the second surface 221. The second support member 40 is connected to the third beam 11 and the fourth beam 12. The sealing structure is also connected to the fifth surface 111 and the sixth surface 121. A portion of the sealing structure is located between the first surface 211 and the fifth surface 111, and a portion of the sealing structure is located between the second surface 221 and the sixth surface 121.

[0130] The third beam 11 refers to the beam structure in the second structural segment 10. The third beam 11 is a supporting structure in the second structural segment 10, providing support and installation foundation for other structures installed on the second structural segment 10.

[0131] The third beam 11 can be a box girder structure, an I-beam structure, or a beam structure of other shapes; the number of third beams 11 can be one, two, or more; the material of the third beam 11 can include metal, plastic, or other materials.

[0132] The third beam 11 has a fifth surface 111 on the side facing the first structural segment 20, that is, the fifth surface 111 is a surface on the third beam 11. At this time, at least a portion of the first structural segment 20 is connected to the third beam 11, and at least a portion of the sealing structure is connected to the third beam 11.

[0133] The fifth surface 111 is connected to the first surface 211. At this time, the third beam 11 is connected to the first beam 21. The length direction of the third beam 11 can be the same as the length direction of the first beam 21. For example, the length direction of the third beam 11 can be parallel to the width direction Y of the chassis 100.

[0134] The fourth beam 12 refers to another beam structure in the second structural segment 10. The fourth beam 12 is also a supporting structure in the second structural segment 10, providing support and installation foundation for other structures installed on the second structural segment 10. The fourth beam 12 can be a box beam structure, an I-beam structure, or a beam structure of other shapes. The material of the fourth beam 12 can include metal, plastic, or other materials.

[0135] The number of fourth beams 12 can be one, two, or more. For example, there can be two fourth beams 12 connected to both sides of the third beam 11. In this case, the two fourth beams 12 and the third beam 11 can enclose an internal space to accommodate structures such as electric drive systems and electric control systems.

[0136] The sixth surface 121 is a surface on the fourth beam 12, and the sixth surface 121 is a surface on the fourth beam 12 facing the first structural segment 20; when the first surface 211 and the second surface 221 are located at different heights of the first structural segment 20, the sixth surface 121 and the fifth surface 111 are also located at different heights.

[0137] When the second structural segment 10 is connected to the first structural segment 20, the fifth surface 111 is connected to the first surface 211, and a portion of the sealing structure is located between the fifth surface 111 and the first surface 211. Both sides of this portion of the sealing structure are connected to the fifth surface 111 and the first surface 211 respectively to seal the gap between the fifth surface 111 and the first surface 211.

[0138] When the second structural segment 10 is connected to the first structural segment 20, the sixth surface 121 is connected to the second surface 221, and a portion of the sealing structure is located between the sixth surface 121 and the second surface 221. Both sides of this portion of the sealing structure are connected to the sixth surface 121 and the second surface 221 respectively to seal the gap between the sixth surface 121 and the second surface 221.

[0139] Since the fourth surface 401 of the second support member 40 is connected to the third surface 301 of the first support member 30, and the third surface 301 is connected to the second surface 221, and the sixth surface 121 is connected to the fourth surface 401, the connection part between the sixth surface 121 and the second surface 221 can correspond to the connection part between the third surface 301 and the second surface 221.

[0140] When the second structural segment 10 is connected to the first structural segment 20, the second support member 40 can better press the sealing structure against the first support member 30. At this time, the sealing structure can better fit the second surface 221, the third surface 301 and the connection between them. At the same time, the sealing structure can also better fit the fourth surface 401, the sixth surface 121 and the connection between them, thereby improving the sealing effect of the sealing structure.

[0141] This embodiment provides some specific structures of the second structural segment 10. The second support member 40 is set at the connection between the third beam 11 and the fourth beam 12, and the fourth surface 401 and the fifth surface 111, and the fourth surface 401 and the sixth surface 121 are all set at obtuse angles. This facilitates the connection of the sealing structure to the third beam 11 and the fourth beam 12, and also enables the sealing structure to be more stably connected to the connection part of the third beam 11 and the fourth beam 12. As a result, the sealing structure can better seal the gap between the connection part of the second structural segment 10 and the first structural segment 20, thereby improving the sealing performance.

[0142] In some embodiments, the second support member 40 is sealed to the third beam 11; and / or the second support member 40 is sealed to the fourth beam 12.

[0143] The second support member 40 is sealed to the third beam 11. The second support member 40 can be sealed to the third beam 11 by welding, sealing bonding or other means. The second support member 40 is sealed to the fourth beam 12. The second support member 40 can also be sealed to the fourth beam 12 by welding, sealing bonding or other means.

[0144] When the second structural section 10 is connected to the first structural section 20, the sealing structure may not be able to cover the connection points between the second support member 40 and the third beam 11, and between the second support member 40 and the fourth beam 12. Therefore, the second support member 40 is sealed to the third beam 11 and / or the fourth beam 12 to improve the overall sealing performance of the chassis 100 and reduce the risk of external impurities (such as gravel, dust, water, etc.) entering the interior of the chassis 100 or the passenger compartment.

[0145] In this embodiment, the second support member 40 is sealed to the third beam 11 and / or the fourth beam 12 to improve the sealing performance of the connection between the second support member 40 and the third beam 11, and the second support member 40 and the fourth beam 12, thereby improving the sealing performance of the entire chassis 100.

[0146] refer to Figure 2 In some embodiments, there are two second structural segments 10, and the two second structural segments 10 are respectively connected to opposite sides of the first structural segment 20.

[0147] There are two second structural sections 10, and the two second structural sections 10 are located on opposite sides of the first structural section 20. At this time, the two second structural sections 10 can serve as the front compartment section and the rear compartment section of the chassis 100, respectively. The front compartment section can be used to arrange the electric drive system, the electronic control system, the steering system, the suspension system, etc., and the rear compartment section can be used to arrange the rear-drive electric drive system, the suspension system, etc.

[0148] When there are two second structural segments 10, both second structural segments 10 have a second structural segment 10, and the two second structural segments 10 are respectively connected to the opposite sides of the first structural segment 20; when a second support member 40 is provided on the second structural segment 10, the two second structural segments 10 are respectively provided with a second support member 40.

[0149] When there are two second structural segments 10, there are also two first structural segments 20 of the first structural segment 20, and the two first structural segments 20 are located on opposite sides of the first structural segment 20. Each first structural segment 20 is provided with one or more first support members 30, and the two first structural segments 20 are respectively connected to the two second structural segments 10.

[0150] For example, the first structural section 20 is the energy storage section, and the two second structural sections 10 are the front storage section and the rear storage section, respectively. The chassis 100 is a three-section structure. When the first beam 21 and the second beam 22 are both part of the housing 51 of the battery device 50, the two second structural sections 10 can be removed from the first structural section 20 to facilitate quick replacement and maintenance of the battery device 50, and also to facilitate the replacement of the battery device 50.

[0151] In this embodiment, the chassis 100 has a three-section structure and there are two second structural sections 10, so that the two second structural sections 10 can be used to support the electric drive system, the electronic control system, the steering system, the suspension system or other systems respectively.

[0152] refer to Figures 3 to 6 In some embodiments, the length direction of the first support member 30 is parallel to the length direction of the second beam 22; or the length direction of the first support member 30 is perpendicular to the length direction of the second beam 22.

[0153] The length direction of the first support member 30 refers to the direction of the long side of the orthographic projection of the third surface 301 along the height direction of the first structural segment 20. The length direction of the first support member 30 can be parallel to the length direction of the second beam 22 or perpendicular to the length direction of the second beam 22. That is, the arrangement of the first support member 30 can be set according to the relative position of the first beam 21 and the second beam 22, or according to the other structures on the first structural segment 20, the space on the first structural segment 20, or according to the structure of the second structural segment 10.

[0154] When a second support member 40 is provided on the second structural segment 10, the second support member 40 can correspond to the first support member 30 so that the sealing structure can better seal the gap between the second structural segment 10 and the first structural segment 20.

[0155] This embodiment provides some positional relationships between the first support member 30 and the second beam 22, so that the first support member 30 can have different installation positions and can adapt to different structures.

[0156] In some embodiments, the sealing structure includes foam or putty.

[0157] Foam refers to a foamed material with sealing properties. Foam has a porous structure and elasticity, allowing it to fill gaps, absorb vibrations, and isolate the environment through its deformation and elasticity, thus achieving a sealing effect. Foam has good elasticity, enabling it to adapt to irregular surfaces; it also has a low density and good insulation and weather resistance. Foam materials can include polyethylene, polyurethane, rubber, or other materials.

[0158] Putty is a highly malleable, uncured adhesive material. It has strong adhesion and can tightly bond to surfaces. After curing, it has high strength, which helps to block debris and achieve a seal. Putty also has good weather resistance and malleability.

[0159] The sealing structure includes foam or putty to effectively seal the gap between the second structural section 10 and the first structural section 20. At the same time, the foam and putty are easy to disassemble and install. When the second structural section 10 is removed from the first structural section 20, the foam or putty is easy to remove and easy to reinstall during the process of reinstalling the second structural section 10 on the first structural section 20.

[0160] This embodiment provides some specific structures for sealing structures, so that the sealing structures can be connected to the first structural segment 20 and can be easily disassembled and replaced.

[0161] In some embodiments, the chassis 100 includes two second structural segments 10, a first structural segment 20, a first support 30, a second support 40, and a sealing structure.

[0162] Two first structural sections 20 are detachably connected to both sides of the first structural section 20 along the length X of the chassis 100.

[0163] The first structural section 20 is equipped with a battery device 50. The first structural section 20 includes two first beams 21 and two second beams 22. The two first beams 21 and the two second beams 22 are part of the structure of the housing 51 of the battery device 50.

[0164] The length direction of the two first beams 21 is parallel to the width direction Y of the chassis 100, and the two first beams 21 are spaced apart along the length direction X of the chassis 100; the length direction of the two second beams 22 is parallel to the length direction X of the chassis 100, the two second beams 22 are spaced apart along the width direction Y of the chassis 100, and the two second beams 22 are connected to the two sides of the first beams 21 along the width direction Y of the chassis 100. The two second beams 22 also serve as the threshold beams of the chassis 100.

[0165] The first beam 21 has a first surface 211 facing the second structural segment 10, and the second beam 22 has a second surface 221 facing the second structural segment 10. A connecting surface connects the first surface 211 and the second surface 221.

[0166] The first support member 30 is sealed to the first surface 211 and the connecting surface. The first support member 30 has a third surface 301 facing the second structural segment 10. The two sides of the third surface 301 are respectively connected to the first surface 211 and the second surface 221.

[0167] The second structural section 10 includes a third beam 11 and a fourth beam 12 connected to the third beam 11. The length direction of the third beam 11 is parallel to the width direction Y of the chassis 100. There are two fourth beams 12, which are respectively connected to both sides of the third beam 11 along its length direction. The length direction of the fourth beam 12 is set at an angle to the length direction of the third beam 11.

[0168] The third beam 11 has a fifth surface 111 on the side facing the first structural segment 20, and the fourth beam 12 has a fourth surface 401 on the side facing the first structural segment 20.

[0169] The second support member 40 is connected to the sealed connection between the third beam 11 and the fourth beam 12, and the second support member 40 has a sixth surface 121 facing the first structural segment 20.

[0170] When the second structural segment 10 is connected to the first structural segment 20, the first surface 211 corresponds to the fifth surface 111, the second surface 221 corresponds to the sixth surface 121, and the third surface 301 corresponds to the fourth surface 401; one side of the sealing structure is connected to the second structural segment 10 and covers a portion of the fifth surface 111, the fourth surface 401, and the two sixth surfaces 121; the other side of the sealing structure is connected to the first structural segment 20 and covers a portion of the first surface 211, the third surface 301, and the two second surfaces 221.

[0171] Secondly, embodiments of this application also provide a vehicle 1000, including a chassis 100 provided in some embodiments of the first aspect.

[0172] In the vehicle 1000, on the second structural section 10 and the first structural section 20 of the chassis 100, the sealing structure can better fit the second structural section 10 and the first structural section 20, and can better seal the gap between the second structural section 10 and the first structural section 20.

[0173] The second structural section 10 and the first structural section 20 are detachable, so as to facilitate the overall replacement of the first structural section 20, or the partial replacement or repair of the battery device 50 on the first structural section 20; during the reinstallation of the second structural section 10 and the first structural section 20, the sealing structure is easy to lay out and can fit tightly to the second structural section 10 and the first structural section 20.
