Description

Technical Field

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

[0002] With the advancement of technology and the improvement of people's living standards, new energy vehicles are attracting increasing market attention due to their advantages such as clean energy and high level of intelligence.

[0003] Improving the space utilization and passenger comfort of vehicles is a research direction in vehicle technology. Utility Model Content

[0004] This application provides an energy compartment, chassis, and vehicle for use in vehicles, which helps to improve space utilization and enhance passenger comfort.

[0005] According to a first aspect of this application, an energy compartment for a vehicle is provided, comprising a frame and battery cells housed within the frame. The frame includes a sill beam and a floor assembly. The sill beam is located on at least one side of the battery cell along the width direction of the vehicle, and has a first recess recessed into a first upper surface of the sill beam, extending through the sill beam along the width direction. The floor assembly includes a floor and a longitudinal beam connected to the floor. The floor is located above the battery cell and connected to the sill beam, and the longitudinal beam is located above the floor. The longitudinal beam and the floor enclose a second recess, which is disposed opposite to and opens toward the first recess along the width direction. Thus, the space between the first and second recesses can be used to arrange a guide rail assembly for a vehicle sliding door, such that the guide rail assembly shares at least a portion of the space in the vehicle height direction with the sill beam, and shares at least a portion of the space in the vehicle width direction with the sill beam and the floor assembly, fully utilizing the existing space of the energy compartment and reducing the additional space occupied by the guide rail assembly in the vehicle width and height directions. As can be seen, the energy compartment provided in this application embodiment can better adapt to the sliding door of the vehicle, which is conducive to reducing the overall width of the vehicle with the energy compartment, lowering the height of the vehicle floor, realizing vehicle miniaturization and improving the user's boarding and alighting experience.

[0006] In some embodiments, the longitudinal beam has a first top wall away from the floor, and the first top wall is provided with a first connecting portion, through which the first top wall can be connected to the upper body of the vehicle. Thus, the longitudinal beam can be connected to the upper body via the first connecting portion, which helps to improve the connection strength and stability between the energy compartment and the upper body.

[0007] In some embodiments, along the width direction, the first top wall has an outer edge near the second recess and an inner edge away from the second recess, with the first connecting portion closer to the inner edge. The first connecting portion is offset from the center of the first top wall in the width direction and is closer to the inner edge of the first top wall, allowing for a larger area to be reserved between the outer edge of the first top wall and the first connecting portion, facilitating the arrangement of a seal on the upper side of the first top wall, thereby achieving a seal between the longitudinal beam and the upper vehicle body.

[0008] In some embodiments, the first top wall has a second upper surface, and a second recess is recessed into the second upper surface. The second recess not only opens toward the first recess but also opens upwards, which facilitates the arrangement of the sliding door guide rail assembly within the second recess and reduces interference.

[0009] In some embodiments, the first top wall has a second upper surface, and the first and second upper surfaces are flush along the height direction of the vehicle. On the one hand, this facilitates the simultaneous connection of the vehicle's upper body to the longitudinal beams and the sill beams, and also facilitates the installation of continuous seals between the upper body and the longitudinal beams, and between the upper body and the sill beams, with each section of the seal at the same height, which is beneficial for improving the sealing effect; on the other hand, the longitudinal beams and the sill beams can share at least a portion of the space in the height direction, which is beneficial for improving space utilization.

[0010] In some embodiments, the floor assembly includes two crossbeams connected to the floor, the crossbeams being disposed on the upper side of the floor, and at least a portion of a longitudinal beam connecting the two crossbeams. This helps to enhance the structural strength of the floor assembly.

[0011] In some embodiments, the sill beam includes a main beam body, a first protrusion, and a second protrusion. Both the first and second protrusions project upwards from the upper surface of the main beam body. The first protrusion is located on one side of the second protrusion along the length direction of the vehicle. The first recess includes a first sub-recess and a second sub-recess. Along the length direction, the first sub-recess is located between the first and second protrusions and extends through the sill beam along the width direction. The second sub-recess is located on the outer side of the first protrusion facing away from the battery cell along the width direction. The sill beam does not need to be completely framed at the top; only a partial frame is needed, with the inner portion remaining to form the first protrusion. The first protrusion and the second sub-recess are correspondingly arranged along the width direction. The first protrusion does not affect the arrangement of the guide rail assembly and can enhance the overall strength of the sill beam.

[0012] In some embodiments, the first protrusion includes a second top wall, a first side wall, and a second side wall. Both the first and second side walls are connected between the second top wall and the main beam. The first side wall forms part of a second sub-recess, and the second side wall is located on the side of the first side wall facing away from the second sub-recess. At least one of the second top wall and the second side wall is provided with a second connecting portion, through which the first protrusion can be connected to the vehicle's torque converter. This facilitates the connection between the energy compartment and the torque converter in both the height and width directions, enhancing the connection strength between the energy compartment and the rear compartment and meeting the requirements for collision and torsional stiffness.

[0013] In some embodiments, the dimension of the first protrusion is smaller than the dimension of the second sub-recess along the width direction. This facilitates the connection between the sill beam and the torsion box, while also providing more installation space for the guide rail assembly, further maximizing the use of the existing space in the sill beam and improving space utilization.

[0014] In some embodiments, a third recess is provided on the side of the sill beam facing the battery cell. The third recess is recessed into the first upper surface and is located on the side of the second protrusion facing the battery cell. A portion of the floor assembly is accommodated in the third recess. The third recess can provide partial accommodating space for the floor assembly, and the floor assembly and the sill beam can share part of the space in the height direction, which is beneficial to improving space utilization and reducing the possibility that the longitudinal beam of the floor assembly will extend upward beyond the third top wall.

[0015] In some embodiments, there are two sill beams and two longitudinal beams. The two sill beams are arranged opposite each other and symmetrically along the width direction, and the two longitudinal beams are arranged opposite each other and symmetrically along the width direction. The two sill beams and two longitudinal beams cooperate to provide installation space for the guide rail assemblies of the two sliding doors of the vehicle, which helps to reduce the overall width of the vehicle with the energy compartment provided in the embodiments of this application.

[0016] According to a second aspect of this application, embodiments of this application also provide a chassis including a front compartment, a rear compartment, and an energy compartment provided according to any embodiment of the first aspect, wherein the energy compartment is connected between the front compartment and the rear compartment along the length direction of the vehicle. The chassis can better accommodate the vehicle's sliding doors, which helps to reduce the overall width of the vehicle with the chassis, lower the height of the vehicle floor, achieve vehicle miniaturization, and improve the user's boarding and alighting experience.

[0017] In some embodiments, the energy cabin is detachably connected to the front cabin and detachably connected to the rear cabin. The energy cabin, front cabin, and rear cabin can form three independent modules. These three independent modules can be independently manufactured in different manufacturing processes and processing environments, which helps to reduce manufacturing difficulty. Furthermore, the appropriate module type can be replaced according to needs, improving adaptability and reducing R&D and maintenance costs.

[0018] In some embodiments, the sill beam includes a main beam body, a first protrusion, and a second protrusion. Both the first and second protrusions project upwards from the upper surface of the main beam body. The first protrusion is located on one side of the second protrusion along the length direction of the vehicle. The first recess includes a first sub-recess and a second sub-recess. Along the length direction, the first sub-recess is located between the first and second protrusions and extends through the sill beam along the width direction. The second sub-recess is located on the outer side of the first protrusion facing away from the battery cell along the width direction. The rear compartment includes a torsion box, which is detachably connected to the first protrusion. This not only enhances the structural strength of the sill beam itself but also connects the first protrusion to the torsion box in the rear compartment, which helps to strengthen the connection strength between the energy compartment and the rear compartment, meeting the requirements for collision and bending / torsional stiffness.

[0019] According to a third aspect of this application, embodiments of this application also provide a vehicle comprising a chassis, an upper body, and a sliding door as provided in any embodiment of the second aspect of this application. The upper body is detachably connected to a sill beam and includes a guide rail assembly, a portion of which is disposed in a first recess and a portion of which is disposed in a second recess. The sliding door is slidably connected to the guide rail assembly. The guide rail assembly is partially disposed in the first and second recesses, sharing at least a portion of the space in the vehicle height direction with the sill beam, and sharing at least a portion of the space in the vehicle width direction with the sill beam and the floor assembly. This allows for full utilization of the existing space in the energy compartment, reducing the additional space occupied by the guide rail assembly in the vehicle width and height directions, thereby better accommodating the sliding door, reducing the overall width of the vehicle, lowering the height of the vehicle floor, achieving vehicle miniaturization, and improving the user's boarding and alighting experience.

[0020] In some embodiments, the longitudinal beam includes a first top wall away from the floor; the upper body includes a first connecting plate, a portion of which is disposed on the upper side of the first top wall and detachably connected to the first top wall. The upper body is not only connected to the sill beam, but also detachably connected to the longitudinal beam via the first connecting plate, which helps to enhance the connection strength between the upper body and the chassis, and improve the connection stability and reliability.

[0021] In some embodiments, the vehicle further includes a seal, at least a portion of which is sandwiched between the first connecting plate and the first top wall. This facilitates a seal between the upper body and the chassis, preventing external impurities such as liquids and solid particles from entering the passenger compartment and improving the passenger experience.

[0022] In some embodiments, the first connecting plate and the first top wall are connected by a first connector, which is located on the inner side of the seal facing away from the second recess along the width direction. The first connector can press the seal tightly, which helps to improve the sealing effect and reduce the possibility of the seal moving out of the gap between the first connecting plate and the first top wall.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0044] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0047] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0050] Electric MPVs (multi-Purpose Vehicles) offer a great option for next-generation mobility with their spacious interiors and superior passenger experience. In particular, the electric sliding doors of MPVs provide a smooth boarding and alighting experience. However, the skateboard chassis that integrates the energy compartment with the vehicle's chassis is difficult to adapt to the sliding door's sliding rails. The placement of the sliding door's sliding rails either encroaches on battery space, affecting the vehicle's range, or occupies significant space in the vehicle's height or width, restricting vehicle miniaturization and impacting the passenger experience.

[0051] In view of this, this application provides a technical solution by providing a first recess on the sill beam of the energy compartment frame and a second recess on the floor assembly of the energy compartment frame. The first recess extends through the sill beam along the width direction of the vehicle and is recessed into the upper surface of the sill beam. The second recess is opposite to the first recess along the width direction of the vehicle and opens towards the first recess. Thus, the space between the first and second recesses can be used to arrange the lower sliding door rail, reducing the additional space occupied by the lower sliding rail in the width and height directions of the vehicle, thereby reducing the overall width of the vehicle and lowering the height of the vehicle floor, which is beneficial for vehicle miniaturization and improving the user's boarding and alighting experience.

[0052] Furthermore, the second recess is enclosed by the floor and longitudinal beams of the floor assembly. The second recess and the battery cell are located on the upper and lower sides of the floor, respectively. The setting of the second recess does not affect the arrangement space of the battery cell, which can maximize the power distribution efficiency of the battery cell and extend the vehicle's driving range.

[0053] The technical solutions provided in this application are applicable to energy cabins, chassis, and vehicles.

[0054] The energy cabin, chassis, and vehicle provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0056] Reference Figures 1 to 7The energy compartment 100 for a vehicle provided in this application embodiment includes a frame 10 and a battery cell 20 housed within the frame 10. The frame 10 includes a sill beam 11 and a floor assembly 12. The sill beam 11 is disposed on at least one side of the battery cell 20 along the width direction X of the vehicle. The sill beam 11 has a first recess 111, which is recessed into a first upper surface 11a of the sill beam 11 and extends through the sill beam 11 along the width direction X. The floor assembly 12 includes a floor 121 and a longitudinal beam 122 connected to the floor 121. The floor 121 is disposed above the battery cell 20 and connected to the sill beam 11. The longitudinal beam 122 is disposed above the floor 121. The longitudinal beam 122 and the floor 121 enclose a second recess 123, which is disposed opposite to the first recess 111 along the width direction X and opens toward the first recess 111.

[0057] The interior of the frame 10 can form a receiving space 13, in which the battery cell 20 is disposed. The sill beam 11 and the floor assembly 12 form at least a portion of the receiving space 13.

[0058] In some embodiments, the frame 10 further includes a base plate 14 disposed below the battery cell 20, and the base plate 14, the floor assembly 12, and the sill beam 11 define an accommodating space 13.

[0059] The sill beam 11 is a side beam of the frame 10 in the width direction X, and the sill beam 11 extends along the length direction Y of the vehicle. In some examples, there may be one sill beam 11, which is located on one side of the battery cell 20 in the width direction X. In other examples, there may be two sill beams 11, which are located on both sides of the battery cell 20 in the width direction X.

[0060] The threshold beam 11 has a first upper surface 11a, which can be a continuous surface or include multiple disjoint surfaces.

[0061] The first recess 111 is recessed downward into the first upper surface 11a and extends through the threshold beam 11 in the width direction X. The first recess 111 is open upward, and at least a portion of the first recess 111 is open to both sides of the threshold beam 11 in the width direction X.

[0062] The sill beam 11 can be formed by machining a profile to remove some material. The area where the profile has some material removed forms the first recess 111.

[0063] The floor assembly 12 is the upper cover assembly of the frame 10 in the vehicle height direction Z, used to cover the battery cells 20. The floor assembly 12 is generally plate-shaped. After the energy compartment 100 is applied to the vehicle, the floor assembly 12 also forms the passenger compartment inside the vehicle to meet the needs of passengers.

[0064] The floor 121 can be connected to the longitudinal beam 122 by screws, riveting, welding, snap-fitting, or other suitable means. Optionally, the longitudinal beam 122 is welded to the floor 121.

[0065] The floor 121 can be connected to the sill beam 11 by screws, riveting, welding, snap-fitting, or other suitable means. Optionally, the floor 121 is connected to the sill beam 11 by screws.

[0066] The longitudinal beam 122 may protrude upward from the upper surface of the floor 121. The longitudinal beam 122 may be adjacent to the edge of the floor 121 in the width direction X so as to form a second recess 123 on the upper side of the area of ​​the floor 121 adjacent to its edge.

[0067] The longitudinal beam 122 can be a stamped part, and the second recess 123 can be formed by stamping.

[0068] The first recess 111 extends through a portion of the sill beam 11 along the width direction X and is opposite to and connected to the second recess 123. The first recess 111 and the second recess 123 together form a larger recess. The second recess 123 can provide additional space for the guide rail assembly of the vehicle sliding door on the upper side of the floor 121.

[0069] The first recess 111 can extend integrally along the length direction Y, and the second recess 123 can extend integrally along the length direction Y. The overall shape formed by the first recess 111 and the second recess 123 can match the sliding path of the vehicle sliding door.

[0070] The battery cell 20 is the smallest unit capable of independent charging and discharging. The battery cell 20 may include lithium-ion rechargeable battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, nano-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, etc. The battery cell 20 may be cylindrical, flat, cuboid, or other shapes. The battery cell 20 may be a cylindrical battery cell, a prismatic battery cell, or a pouch battery cell.

[0071] The energy compartment 100 provided in this embodiment can utilize the space of the first recess 111 and the second recess 123 to arrange the guide rail assembly of the vehicle sliding door, so that the guide rail assembly shares at least part of the space in the vehicle height direction Z with the sill beam 11, and shares at least part of the space in the vehicle width direction X with the sill beam 11 and the floor assembly 12. This fully utilizes the existing space of the energy compartment 100 and reduces the additional space occupied by the guide rail assembly in the vehicle width direction X and height direction Z. Therefore, the energy compartment 100 provided in this embodiment can better adapt to the vehicle's sliding door, which is beneficial for reducing the overall width of the vehicle with the energy compartment 100, lowering the height of the vehicle floor (the distance between the step surface for getting in and out of the vehicle and the ground), achieving vehicle miniaturization and improving the user's boarding and alighting experience.

[0072] Furthermore, the second recess 123 is enclosed by the floor 121 and the longitudinal beam 122. The second recess 123 and the battery cell 20 are located on the upper and lower sides of the floor 121, respectively. The arrangement of the second recess 123 does not affect the arrangement space of the battery cell 20, which can maximize the power distribution efficiency and extend the vehicle's driving range.

[0073] In some embodiments, the longitudinal beam 122 has a first top wall 1221 away from the floor 121, the first top wall 1221 is provided with a first connecting portion 1222, and the first top wall 1221 can be connected to the upper body of the vehicle through the first connecting portion 1222.

[0074] The longitudinal beam 122 can be a profile formed by stamping, with an internal cavity, which can reduce the weight of the energy compartment 100.

[0075] The first connecting portion 1222 can be a connecting hole, and the first top wall 1221 is connected to the upper body of the vehicle through a connector passing through the connecting hole. Optionally, the first connecting portion 1222 can be a screw hole.

[0076] The second recess 123 is used to accommodate a part of the upper body of the vehicle (part of the guide rail assembly of the sliding door). The portion of the guide rail assembly accommodated in the second recess 123 is relatively far from the sill beam 11, making it difficult to connect with the sill beam 11. In this embodiment, by providing a first connecting portion 1222 on the first top wall 1221, the longitudinal beam 122 can be connected to the upper body through the first connecting portion 1222, which helps to improve the connection strength and stability between the energy compartment 100 and the upper body.

[0077] In some embodiments, along the width direction X, the first top wall 1221 has an outer edge 1221a near the second recess 123 and an inner edge 1221b away from the second recess 123, and the first connecting portion 1222 is closer to the inner edge 1221b.

[0078] The inner edge 1221b of the first top wall 1221 is closer to the center of the energy chamber 100 in the width direction X than the outer edge 1221a.

[0079] The first connecting portion 1222 is offset from the center of the first top wall 1221 in the width direction X and is closer to the inner edge 1221b of the first top wall 1221. A larger area can be reserved between the outer edge 1221a of the first top wall 1221 and the first connecting portion 1222 to facilitate the arrangement of a sealing element on the upper side of the first top wall 1221, thereby achieving a seal between the longitudinal beam 122 and the upper vehicle body.

[0080] In some embodiments, the first top wall 1221 has a second upper surface 1221c, and the second recess 123 is recessed in the second upper surface 1221c.

[0081] The longitudinal beam 122 may include a longitudinal beam body 1223 and two limiting portions 1224. The two limiting portions 1224 are arranged opposite each other along the length direction Y and are respectively connected to both ends of the longitudinal beam body 1223 along the length direction Y. Along the length direction Y, the second recess 123 may be located between the two limiting portions 1224.

[0082] The second upper surface 1221c may include the upper surface of the longitudinal beam body 1223 and the upper surfaces of the two limiting parts 1224.

[0083] The second recess 123 not only opens towards the first recess 111, but also opens upwards, which is beneficial for arranging the guide rail assembly of the sliding door in the second recess 123 and reducing interference.

[0084] In some embodiments, the first top wall 1221 has a second upper surface 1221c, and the first upper surface 11a and the second upper surface 1221c are flush along the height direction Z of the vehicle.

[0085] The longitudinal beam 122 does not extend upward beyond the sill beam 11, and the sill beam 11 does not extend upward beyond the longitudinal beam 122. On the one hand, this facilitates the simultaneous connection of the vehicle's upper body to both the longitudinal beam 122 and the sill beam 11, and also facilitates the installation of continuous seals between the upper body and the longitudinal beam 122, as well as between the upper body and the sill beam 11. Since each section of the seal is at the same height, it helps to improve the sealing effect. On the other hand, the longitudinal beam 122 and the sill beam 11 can share at least part of the space in the height direction Z, which helps to improve space utilization.

[0086] In some embodiments, the floor assembly 12 includes two crossbeams 124 connected to the floor 121, the crossbeams 124 being disposed on the upper side of the floor 121, and at least a portion of the longitudinal beam 122 being connected between the two crossbeams 124.

[0087] Two crossbeams 124 may be arranged opposite each other and spaced apart along the length direction Y. The crossbeams 124 may be used to connect structures located inside the upper body of the vehicle, such as seats.

[0088] Optionally, at least a portion of the longitudinal beam 122 may be connected between the ends of the two transverse beams 124 in the width direction X.

[0089] Optionally, the longitudinal beam body 1223 is connected between two transverse beams 124.

[0090] The longitudinal beam 122 is at least partially connected to the two transverse beams 124, which helps to enhance the structural strength of the floor assembly 12.

[0091] In some embodiments, along the height direction Z, the upper surface of the crossbeam 124 is flush with the second upper surface 1221c of the first top wall 1221. Thus, the longitudinal beam 122 can share the space in the height direction Z with the crossbeam 124, and the arrangement of the longitudinal beam 122 does not occupy additional height space, nor does it increase the dimensions of the floor assembly 12 in the height direction Z.

[0092] In some embodiments, the sill beam 11 includes a main beam body 112, a first protrusion 113, and a second protrusion 114. Both the first protrusion 113 and the second protrusion 114 protrude upward from the upper surface of the main beam body 112. The first protrusion 113 is located on one side of the second protrusion 114 along the length direction Y of the vehicle. The first recess 111 includes a first sub-recess 1111 and a second sub-recess 1112. Along the length direction Y, the first sub-recess 1111 is located between the first protrusion 113 and the second protrusion 114, and extends through the sill beam 11 along the width direction X. The second sub-recess 1112 is located on the outside of the first protrusion 113 along the width direction X, facing away from the battery cell 20.

[0093] The first protrusion 113 and the second protrusion 114 are both integrally located on the upper side of the main beam 112.

[0094] Optionally, the main beam 112, the first protrusion 113, and the second protrusion 114 are integrally formed structures.

[0095] The upper surface of the main beam 112 forms the bottom surface of the first recess 111.

[0096] Along the length direction Y, the first protrusion 113 may be located behind the second protrusion 114 along the vehicle travel direction.

[0097] The first protrusion 113 and the second protrusion 114 may be separated by the first sub-recess 1111. Along the height direction Z, the upper surface of the first protrusion 113 and the upper surface of the second protrusion 114 are flush, and the first upper surface 11a may include the upper surface of the first protrusion 113 and the upper surface of the second protrusion 114.

[0098] The first sub-recess 1111 forms a channel that passes through the sill beam 11 along the width direction X, which facilitates the transition of a portion of the guide rail assembly through the first sub-recess 1111 to the second recess 123.

[0099] The second recess 1112 opens outwards from the first protrusion 113 and upwards, facilitating the arrangement of the guide rail assembly.

[0100] Along the width direction X, the size of the first sub-recess 1111 is larger than the size of the second sub-recess 1112.

[0101] The guide rail assembly requires a narrow installation space in the rear end region along the length direction Y, and the second sub-recess 1112 does not need a large dimension in the width direction X. Therefore, the sill beam 11 does not need to be completely mounted on its upper half; only a partial mounting is required, with the inner portion retained to form the first protrusion 113. The first protrusion 113 and the second sub-recess 1112 are correspondingly arranged along the width direction X. The first protrusion 113 does not affect the arrangement of the guide rail assembly and can enhance the overall strength of the sill beam 11.

[0102] In some embodiments, the first protrusion 113 includes a second top wall 1131, a first side wall 1132, and a second side wall 1133. Both the first side wall 1132 and the second side wall 1133 are connected between the second top wall 1131 and the main beam 112. The first side wall 1132 forms a portion enclosing the second sub-recess 1112, and the second side wall 1133 is located on the side of the first side wall 1132 facing away from the second sub-recess 1112. At least one of the second top wall 1131 and the second side wall 1133 is provided with a second connecting portion 1134, through which the first protrusion 113 can be connected to the vehicle's torque converter.

[0103] The first sidewall 1132 and the second sidewall 1133 are arranged opposite each other along the width direction X, and the first sidewall 1132 is closer to the second sub-recess 1112 than the second sidewall 1133.

[0104] The second top wall 1131 and the second side wall 1133 may each be provided with a second connecting part 1134, or only the second top wall 1131 may be provided with a second connecting part 1134, or only the second side wall 1133 may be provided with a second connecting part 1134.

[0105] The second connecting portion 1134 can be a connecting hole, and at least one of the second top wall 1131 and the second side wall 1133 can be connected to the vehicle's torque box through a connector passing through the connecting hole. Optionally, the second connecting portion 1134 can be a screw hole.

[0106] The vehicle's torque pack can be a rear torque pack, located in the vehicle's rear compartment. The second top wall 1131 can be connected to the vehicle's torque pack via the second connecting part 1134, achieving a connection between the energy compartment 100 and the torque pack in the height direction Z. The second side wall 1133 can also be connected to the vehicle's torque pack via the second connecting part 1134, achieving a connection between the energy compartment 100 and the torque pack in the width direction X. This enhances the connection strength between the energy compartment and the rear compartment, meeting the requirements for collision and bending / torsional stiffness.

[0107] In some embodiments, along the width direction X, the size of the first protrusion 113 is smaller than the size of the second sub-recess 1112.

[0108] The first protrusion 113 has a relatively small dimension in the width direction X, which allows for an increase in the dimension of the second sub-recess 1112 in the width direction X. This not only facilitates the connection between the sill beam 11 and the torsion box, but also provides a larger installation space for the guide rail assembly, further maximizing the use of the existing space in the sill beam 11 and improving space utilization.

[0109] In some embodiments, the second protrusion 114 includes a third top wall 1141, the third top wall 1141 is provided with a third connecting portion 1142, and the second protrusion 114 can be connected to the upper body of the vehicle through the third connecting portion 1142.

[0110] The third connecting portion 1142 can be a connecting hole, and the second protrusion 114 can be connected to the upper body of the vehicle through a connector passing through the connecting hole. Optionally, the third connecting portion 1142 can be a screw hole.

[0111] Along the width direction X, the third top wall 1141 has an outer edge away from the battery cell 20 and an inner edge close to the battery cell 20, and the third connecting part 1142 is closer to the outer edge of the third top wall 1141 to facilitate the connection operation between the energy compartment 100 and the upper body.

[0112] In some embodiments, the sill beam 11 has a third recess 115 on the side facing the battery cell 20. The third recess 115 is recessed into the first upper surface 11a and is located on the side of the second protrusion 114 facing the battery cell 20. A portion of the floor assembly 12 is accommodated in the third recess 115.

[0113] The third recess 115 opens upwards and is open along the width direction X toward the side facing the battery cell 20. The edge of the floor assembly 12 along the width direction X can be accommodated in the third recess 115.

[0114] The second protrusion 114 may include a third sidewall 1143 and a fourth sidewall 1144 disposed opposite to each other along the width direction X. The third sidewall 1143 and the fourth sidewall 1144 are both connected between the main beam 112 and the third top wall 1141. The fourth sidewall 1144 forms part of the enclosure of the third recess 115. The third sidewall 1143 is located on the outside of the fourth sidewall 1144 along the width direction X, facing away from the battery cell 20.

[0115] The floor 121 may be connected to the fourth side wall 1144 by screws, snap-fit, welding or other suitable means.

[0116] The third recess 115 can provide partial accommodating space for the floor assembly 12. The floor assembly 12 and the threshold beam 11 can share part of the space in the height direction Z, which is beneficial to improving space utilization and reducing the possibility that the longitudinal beam 122 of the floor assembly 12 may extend upward beyond the third top wall 1141.

[0117] In some embodiments, there are two threshold beams 11 and two longitudinal beams 122. The two threshold beams 11 are arranged opposite to each other and symmetrically along the width direction X, and the two longitudinal beams 122 are arranged opposite to each other and symmetrically along the width direction X.

[0118] The two sill beams 11, the floor assembly 12, and the base plate 14 together define the receiving space 13. The two sill beams 11 are located on both sides of the battery cell 20 along the width direction X.

[0119] The two sill beams 11 and the two longitudinal beams 122 work together to provide installation space for the guide rail assemblies of the two sliding doors of the vehicle, which helps to reduce the overall width of the vehicle with the energy compartment 100 provided in the embodiments of this application.

[0120] According to a second aspect of this application, embodiments of this application also provide a chassis 200, which includes a front compartment 300, a rear compartment 400, and an energy compartment 100 provided in any embodiment of this application. Along the length Y direction of the vehicle, the energy compartment 100 is connected between the front compartment 300 and the rear compartment 400.

[0121] The energy compartment 100 can be connected to the forward compartment 300 and the aft compartment 400 by means of screws, welding, snap-fitting, riveting or other suitable methods.

[0122] The chassis 200 can be a skateboard chassis, which has a high degree of integration and helps to reduce R&D costs.

[0123] The chassis 200 provided in this application embodiment can better adapt to the sliding doors of the vehicle, which is conducive to reducing the overall width of the vehicle with the chassis 200, lowering the height of the vehicle floor, realizing vehicle miniaturization and improving the user's boarding and alighting experience.

[0124] In some embodiments, the energy cabin 100 is detachably connected to the front cabin 300 and the energy cabin 100 is detachably connected to the rear cabin 400.

[0125] The energy compartment 100 and the forward compartment 300 can be detachably connected by screws, snap-fit, or other suitable means. The energy compartment 100 and the aft compartment 400 can also be detachably connected by screws, snap-fit, or other suitable means.

[0126] Optionally, the front compartment 300 and the rear compartment 400 are detachably connected by fasteners such as screws, which provides a stronger connection and helps improve the stability and reliability of the chassis 200.

[0127] Optionally, the front cabin 300 and the rear cabin 400 can be connected to the sill beam 11 of the energy cabin 100 to improve the convenience and reliability of the connection.

[0128] The energy chamber 100 and the front chamber 300 are detachably connected, and the energy chamber 100 and the rear chamber 400 are detachably connected. The energy chamber 100, the front chamber 300 and the rear chamber 400 can form three independent modules. The three independent modules can be independently prepared in different preparation processes and processing environments, which helps to reduce the difficulty of preparation. In addition, the appropriate module type can be replaced according to the needs, improving adaptability and reducing R&D costs and maintenance costs.

[0129] In some embodiments, the sill beam 11 includes a main beam body 112, a first protrusion 113, and a second protrusion 114. Both the first protrusion 113 and the second protrusion 114 protrude upwards from the upper surface of the main beam body 112. The first protrusion 113 is located on one side of the second protrusion 114 along the length direction of the vehicle. The first recess 111 includes a first sub-recess 1111 and a second sub-recess 1112. Along the length direction Y, the first sub-recess 1111 is located between the first protrusion 113 and the second protrusion 114, and extends through the sill beam 11 along the width direction X. The second sub-recess 1112 is located on the outside of the first protrusion 113 along the width direction X, facing away from the battery cell 20. The rear compartment 400 includes a torque box 401, which is detachably connected to the first protrusion 113.

[0130] Torque box 401 can be detachably connected to the first protrusion 113 by screw connection, snap-fit ​​or other suitable means.

[0131] The second top wall 1131 and the second side wall 1133 of the first protrusion 113 may both be provided with a second connecting part 1134, and the first protrusion 113 is connected to the torque box 401 through the second connecting part 1134.

[0132] Optionally, the second connecting part 1134 can be a connecting hole, and the second top wall 1131 and the second side wall 1133 can be connected to the torque box 401 in both the height direction Z and the width direction X through the connector 402 passing through the connecting hole.

[0133] In this embodiment, a first protrusion 113 is provided on the sill beam 11, which not only enhances the structural strength of the sill beam 11 itself, but also connects the first protrusion 113 to the torsion box 401 of the rear compartment 400, which helps to enhance the connection strength between the energy compartment 100 and the rear compartment 400 and meet the requirements of collision and bending torsional stiffness.

[0134] Figure 9 This is a structural schematic diagram of a vehicle provided in some embodiments of this application. (Refer to...) Figures 1 to 9According to a third aspect of this application, embodiments of this application also provide a vehicle 1000, which includes a chassis 200, an upper body 500, and a sliding door (not shown) provided in any embodiment of the second aspect of this application. The upper body 500 is detachably connected to a sill beam 11, and the upper body 500 includes a guide rail assembly 501, a portion of which is disposed in a first recess 111, and a portion of which is disposed in a second recess 123. The sliding door is slidably connected to the guide rail assembly 501.

[0135] The upper body 500 can be detachably connected to the sill beam 11 by screws, snap-fit, or other suitable means.

[0136] Optionally, the upper body 500 is detachably connected to the sill beam 11 by fasteners such as screws.

[0137] The guide rail assembly 501 is used to guide the sliding door's movement. The guide rail assembly 501 may include a guide rail box 5011 and a guide rail 5012 mounted within the guide rail box 5011. The sliding door can slide along the guide rail 5012.

[0138] The upper body 500 and chassis 200 are detachably connected, which facilitates the separation and decoupling of the upper body and chassis 200, making it easy to replace the upper body 500 as needed and improving adaptability. Furthermore, the guide rail assembly 501 is partially located in the first recess 111 and the second recess 123. The guide rail assembly 501 shares at least a portion of the space in the vehicle height direction Z with the sill beam 11, and shares at least a portion of the space in the vehicle width direction X with the sill beam 11 and the floor assembly 12. This fully utilizes the existing space of the energy compartment 100, reducing the additional space occupied by the guide rail assembly 501 in the vehicle width direction X and height direction Z, thereby better adapting to the sliding door. This helps to reduce the overall width of the vehicle 1000, lower the height of the vehicle 1000 floor, achieve miniaturization of the vehicle 1000, and improve the user's boarding and alighting experience.

[0139] In some embodiments, the longitudinal beam 122 includes a first top wall 1221 remote from the floor 121. The upper body 500 includes a first connecting plate 502, a portion of which is disposed on the upper side of the first top wall 1221 and detachably connected to the first top wall 1221.

[0140] The first connecting plate 502 can be connected to the guide rail assembly 501. At least a portion of the first connecting plate 502 extends beyond the inner surface of the guide rail assembly 501 along the width direction X and extends to the upper side of the first top wall 1221.

[0141] The first connecting plate 502 can be detachably connected to the first top wall 1221 by screws, snap-fit, or other suitable means.

[0142] The upper body 500 is not only connected to the sill beam 11, but also detachably connected to the longitudinal beam 122 through the first connecting plate 502, which helps to enhance the connection strength between the upper body 500 and the chassis 200 and improve the connection stability and reliability.

[0143] In some embodiments, the vehicle 1000 further includes a seal 700, at least a portion of which is sandwiched between the first connecting plate 502 and the first top wall 1221.

[0144] The seal 700 can be made of an elastic, compressible material, such as rubber or foam. The seal 700 can also be formed by curing a colloid.

[0145] Optionally, the seal 700 may be cured from butyl sealant. The seal 700 may be pre-applied to the upper surface of the first top wall 1221 before the first connecting plate 502 is pressed onto the first top wall 1221; alternatively, the first connecting plate 502 may be assembled onto the first top wall 1221 first, and then the seal 700 may be squeezed between the first connecting plate 502 and the first top wall 1221.

[0146] The seal 700 can be entirely clamped between the first connecting plate 502 and the first top wall 1221, or only a part of the seal 700 can be clamped between the first connecting plate 502 and the first top wall 1221. Another part of the seal 700 can be clamped in other contact areas between the upper body 500 and the chassis 200, for example.

[0147] Optionally, the seal 700 may be an integral ring, and the seal 700 may be sandwiched between the upper body 500 and the chassis 200. The seal 700 may be located on the upper side of the integrated casting of the front compartment 300, the second protrusion 114 of the two sill beams 11, the two longitudinal beams 122, the two torque boxes 401 of the rear compartment 400, and the intermediate connecting plate 403 connecting the two torque boxes 401.

[0148] The first connecting plate 502 and the first top wall 1221 form a partial contact area between the upper body 500 and the chassis 200. The sealing element 700 is sandwiched between the first connecting plate 502 and the first top wall 1221, which helps to achieve a seal between the upper body 500 and the chassis 200, and can prevent external impurities such as liquids and solid particles from entering the passenger compartment, thus improving the passenger experience.

[0149] The vehicle 1000 in this embodiment of the application achieves the decoupling connection and sealing requirements between the chassis 200 and the upper body by setting the longitudinal beam 122, which is beneficial to improving the adaptability and performance of the vehicle 1000.

[0150] In some embodiments, the first connecting plate 502 and the first top wall 1221 are connected by a first connector 801, which is located on the inner side of the seal 700 facing away from the second recess 123 along the width direction X.

[0151] The first top wall 1221 is provided with a first connecting part 1222, which can be a connecting hole.

[0152] The first connecting plate 502 is provided with a connecting hole, and the first connecting member 801 can be a fastener. The first connecting member 801 passes through the connecting hole of the first connecting part 1222 and the first connecting plate 502, thereby detachably connecting the first connecting plate 502 and the first top wall 1221.

[0153] The first connector 801 is closer to the inner edge of the first top wall 1221 than the seal 700. The first connector 801 is also closer to the inner edge of the first connecting plate 502. The first connector 801 can press the seal 700, which helps to improve the sealing effect and reduces the possibility of the seal 700 moving out of the gap between the first connecting plate 502 and the first top wall 1221.
