Description

Vehicle body and vehicle

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 28, 2024, with application number 202410223334.9 and application name “A Vehicle Body and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of automobile parts, and in particular to a vehicle body and a vehicle. Background Art

[0003] In recent years, my country's automotive industry has experienced rapid growth, and it remains a core industry for future development. With the continuous advancement of technology and the continuous improvement of people's living standards, the demand for automotive performance is also increasing. Among these, the B-pillar is often included in the structure of an automobile. The B-pillar refers to the area between the front and rear doors of the vehicle. The main function of the B-pillar is to withstand side impact forces, fully ensuring the safety of the driver and passengers, while also providing support for the entire vehicle structure.

[0004] However, to enhance ingress and egress convenience and provide a better riding experience, the development of B-pillar-less vehicles has become a new trend in vehicle development. This allows users to sit directly into the vehicle, rather than crawling inside. It also expands the use of the seats, allowing for 180-degree seat rotation, creating a work-from-home experience. Furthermore, the door openings will be more than double the size of current models on the market. Therefore, the B-pillar-less design is crucial for ensuring vehicle safety. Summary of the Invention

[0006] The embodiments of the present application provide a body and a vehicle, which is used to solve the problem raised in the above-mentioned background technology that in most cars at this stage, the door sill and the battery are often connected by a row of bolts. After the body structure without B-pillar is set, the battery invades the structural parts of the body more, and the collision safety requirements of the battery are higher. The protection of the battery and the development of the safety performance of the vehicle have become one of the important technical difficulties hindering this development, restricting the progress of the mass production of the body without B-pillar. The development of the body without B-pillar has brought about changes in the body structure, especially the weakening of the force transmission structure of the door sill and the reduction of the layout space, resulting in a reduction in collision safety performance and the battery being squeezed and deformed. Therefore, the structure needs to be further studied and improved to meet the requirements of the automobile evaluation regulations.

DETAILED DESCRIPTION

[0043] As described in the background art, in most current vehicles, the door sills and batteries are often connected by a row of bolts. With a B-pillar-less body structure, the battery intrudes even more deeply into the structural components of the vehicle body, and higher collision safety requirements are required for the battery. Battery protection and the development of vehicle safety performance have become major technical obstacles hindering this development, restricting the mass production of B-pillar-less bodies. The development of B-pillar-less bodies has brought about structural changes to the vehicle body, particularly the weakening of the force transmission structure of the door sills and the reduction of their layout space. This has led to reduced collision safety performance and extrusion deformation of the battery. Therefore, further research and improvement of the structure is needed to meet the requirements of automotive evaluation regulations.

[0044] In response to the above technical problems, an embodiment of the present application provides a body and a vehicle, wherein the body includes a battery assembly, a door sill beam, and a floor longitudinal beam. The battery assembly has a first mounting portion and a second mounting portion on the side facing the door sill beam, one end of the battery assembly is connected to the door sill beam via the first mounting portion, and the other end of the battery assembly is connected to the floor longitudinal beam via the second mounting portion. The vehicle includes the above-mentioned body. In this way, the embodiment of the present application can improve the battery installation point based on the maximization of the battery volume in a body structure without a B-pillar, and ensure the side collision performance of the vehicle on the basis of maximizing the use of the door sill space. The impact of a body without a B-pillar on the side collision performance and related door mechanisms is resolved, ensuring that the battery cells are not squeezed during a collision and meeting the collision requirements.

[0045] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0046] Figure 1 is a schematic diagram of a partial structure of a vehicle body 100. As shown in Figure 1 , the vehicle body 100 may include a door 600 and a sill beam 300. Due to its structural characteristics, the sill beam 300 may be composed of a plurality of cross beams 31 and longitudinal beams 32. This allows the sill beam 300 to enclose a closed space 33 through the cross beams 31 and longitudinal beams 32. Thus, the sill beam 300 may have a closed cavity 33.

[0047] However, the vehicle body 100 shown in FIG1 has the following defects: when the vehicle body 100 is set without a B-pillar, the strength of the vehicle body 100 needs to maintain the strength and rigidity of the vehicle body 100 compared to the vehicle body 100 with a B-pillar. When the side of the vehicle body 100 encounters a collision, the closed cavity 33 of the sill beam 300 has a relatively single force transmission path and may not be able to resist collision deformation well, and cannot protect the battery cells in the vehicle.

[0048] To address the aforementioned issues, the present invention provides a vehicle body and vehicle. In a B-pillar-less vehicle structure, the battery mounting point is improved to maximize battery volume. This maximizes the use of the door sill space while ensuring the vehicle's side impact performance. The specific structures of the vehicle body and vehicle provided in the present invention are described below in conjunction with the accompanying drawings.

[0049] 2 , a first aspect of an embodiment of the present application provides a vehicle body 100, which may include a battery assembly 200, a door sill beam 300, and a floor stringer 400. The door sill beam 300 may be located on one side of the floor stringer 400, and the door sill beam 300 and the floor stringer 400 may form a frame of the vehicle body 100. In an embodiment of the present application, the side of the battery assembly 200 facing the door sill beam 300 may have a first mounting portion 210, and correspondingly, the side of the battery assembly 200 facing the floor stringer 400 may have a second mounting portion 220. In one possible implementation, one end of the battery assembly 200 may be connected to the door sill beam 300 via the first mounting portion 210, while the other end of the battery assembly 200 may be connected to the floor stringer 400 via the second mounting portion 220.

[0050] Continuing to refer to Figure 2, in the specific implementation of this embodiment, the battery assembly 200 may include: a battery body 230. In one possible implementation, due to the structural characteristics of the door sill beam 300 and the floor longitudinal beam 400, they can be composed of a plurality of cross beams and longitudinal beams respectively, so the door sill beam 300 and the floor longitudinal beam 400 may have a stepped structure. However, in one possible implementation, the battery body 230 may be rectangular, and the present application does not limit the shape of the battery body 230. Therefore, the battery body 230 can be connected to the door sill beam 300 and the floor longitudinal beam 400 by providing a first mounting portion 210 and a second mounting portion 220. In the embodiment of the present application, the battery body 230 can be connected to the first mounting portion 210 and the second mounting portion 220 so that the battery body 230 can be fixed within the vehicle body 100.

[0051] Referring to Figures 2 and 3 , based on the above embodiment, the first mounting portion 210 may have a first mounting point 211, and correspondingly, the second mounting portion 220 may have a second mounting point 221. In one possible implementation, there may be multiple first mounting points 211 and multiple second mounting points 221, and this application does not limit the number of these points. It is understood that the first mounting portion 210 may also be provided with a first fastener 212, and correspondingly, the second mounting portion 220 may also be provided with a second fastener 222. In one possible implementation, there may be multiple first fasteners 212 and multiple second fasteners 222, and this application does not limit the number of these points. The first fasteners 212 may correspond one-to-one with the first mounting points 211, and the second fasteners 222 may correspond one-to-one with the second mounting points 221. Thus, in the embodiment of the present application, the first mounting portion 210 and the sill beam 300 can be connected by a plurality of first fasteners 212 and a plurality of first mounting points 211, and the second mounting portion 220 and the floor longitudinal beam 400 can also be connected by a plurality of second fasteners 222 and a plurality of second mounting points 221. In one possible implementation, the first fasteners and the second fasteners can be bolts, and the present application does not limit the first fasteners and the second fasteners.

[0052] Continuing with FIG. 3 , based on the above embodiment, a plurality of first mounting points 211 can be arranged in parallel along the length of the battery body 230, and correspondingly, a plurality of second mounting points 221 can also be arranged in parallel along the length of the battery body 230. In this way, the plurality of first mounting points 211 can form a row, and the plurality of second mounting points 221 can also form a row. The plurality of first mounting points 211 and the plurality of second mounting points 221 provide a more stable connection to the battery body 230, thereby improving the rigidity of the connection between the battery body 230 and the vehicle body 100.

[0053] Continuing with reference to FIG. 3 , based on the above embodiment, the plurality of first mounting points 211 and the plurality of second mounting points 221 may be staggered in the width direction of the battery body 230. It will be appreciated that the orthographic projections of at least some of the plurality of second mounting points 221 toward the plurality of first mounting points 211 do not overlap with the plurality of first mounting points 211. Thus, staggering a whole row of first mounting points 211 and a whole row of second mounting points 221 allows for a more even distribution of the plurality of first mounting points 211 and the plurality of second mounting points 221 when the vehicle 800 is subjected to a side collision, thereby distributing the collision force, better resisting collision deformation, and protecting the battery body 230.

[0054] Continuing with Figure 2 , based on the above embodiment, the first mounting portion 210 can be lower than the second mounting portion 220 in the thickness direction of the battery body 230. In this embodiment, the first mounting portion 210 can be located at a lower position on the door sill beam 300, while the second mounting portion 220 can be located at a higher position on the floor longitudinal beam 400. This maximizes the battery volume and, therefore, the battery's endurance.

[0055] Continuing to refer to FIG2 , based on the above embodiment, the vehicle body 100 may further include: a first cavity 310. The sill beam 300 may have a first cavity 310. Due to its own structural characteristics, the sill beam 300 may be composed of a plurality of cross beams and longitudinal beams, so that the sill beam 300 can form a closed space through the cross beams or longitudinal beams. Therefore, the sill beam 300 may have a first cavity 310. In the embodiment of the present application, in one possible implementation, one end of a plurality of first fasteners 212 may extend into the first cavity 310, and the other end of the plurality of first fasteners 212 may be connected to the first mounting portion 210 through a plurality of first mounting points 211, so that the first mounting portion 210 is connected to the sill beam 300 and the first cavity 310 through the plurality of first fasteners 212 passing through the plurality of first mounting points 211.

[0056] Continuing with Figure 2 , based on the above embodiment, the vehicle body 100 may further include a floor 500 . The sill beam 300 is located on one side of the floor 500 . In one possible implementation, the floor 500 may be rectangular. Of course, in other embodiments, the floor 500 may also have other shapes. This application does not limit the shape of the floor 500 . In this embodiment of the application, the interior space enclosed by the floor longitudinal beam 400 , the floor 500 , and the sill beam 300 may form a second cavity 410 . Due to its inherent structural characteristics, the floor longitudinal beam 400 may be composed of a plurality of transverse beams and longitudinal beams. In one possible implementation, one end of the plurality of second fasteners 222 can extend into the second cavity 410, and the other ends of the plurality of second fasteners 222 can be connected to the second mounting portion 220 through the plurality of second mounting points 221, so that the second mounting portion 220 is connected to the floor longitudinal beam 400 and the second cavity 410 through the plurality of second fasteners 222 passing through the plurality of second mounting points 221.

[0057] Continuing with FIG. 2 , based on the above embodiment, the vehicle body 100 may further include a door 600 and a divider 700. The divider 700 may be located between the door 600 and the sill beam 300. In one possible implementation, a gap may exist between the door 600 and the sill beam 300, and the divider 700 may be located in the gap between the door 600 and the sill beam 300. One side of the divider 700 may be connected to the sill beam 300 to secure the divider 700 to the sill beam 300. In this embodiment of the present application, when the door 600 is closed, the interior space enclosed by the door 600 and the divider 700 may form a third cavity 710. The placement of the divider 700 thus enhances the force transmission path between the door 600 and the sill beam 300. Notably, the divider 700 may be positioned parallel to the first mounting portion 210 in the width direction of the vehicle body 100. When the side of the vehicle body 100 encounters a collision, the separator 700 can partially resist the collision force on the first mounting portion 210 inside the separator 700 , thereby protecting the battery body 230 inside the vehicle body 100 .

[0058] 2 and 4 , in the embodiment of the present application, the vehicle body 100 may have at least two doors 600, with corresponding sill beams 300 disposed below each of the doors 600. The sill beams 300 may be located on either side of the floor 500 in the width direction, so that passengers can enter the vehicle body 100 through the sill beams 300. It will be appreciated that, compared to the enclosed cavity of the sill beam 300 in the prior art, the size of the first cavity 310 may be slightly smaller than that of the enclosed cavity, providing sufficient space for the third cavity 710 on one side of the first cavity 310, thereby enhancing the force transmission path between the vehicle door 600 and the sill beam 300.

[0059] Based on the above embodiment, the threshold beam 300 can be located on both sides of the battery assembly 200 on the width of the battery body 230. In this way, each side of the battery assembly 200 facing the threshold beam 300 can have a first mounting portion 210 and a second mounting portion 220, providing protection for both sides of the vehicle body.

[0060] Continuing with reference to FIG. 2 , based on the above embodiment, the third cavity 710, the first cavity 310, and the second cavity 410 can be arranged side by side in the width direction of the vehicle body 100. A partition 700 is provided between the third cavity 710 and the first cavity 310, and a sill beam 300 is provided between the first cavity 310 and the second cavity 410, so that the first cavity 310, the second cavity 410, and the third cavity 710 are separated from each other to form three independent cavities. In this embodiment of the present application, the third cavity 710, the first cavity 310, and the second cavity 410 are arranged side by side in the width direction of the vehicle body 100. When the vehicle 800 is hit from the side, the force transmission path between the door 600 and the sill beam 300 is enhanced, thereby increasing the vehicle 800's bending resistance in the side impact direction. The force transmission path between the vehicle door 600 and the threshold beam 300 is transmitted from the third cavity 710 to the first cavity 310 and then to the second cavity 410, so that the intensity of the force decreases gradually, which effectively protects the battery body 230 located under the floor longitudinal beam 400, better resists collision deformation, and further protects the battery cells inside the battery body 230.

[0061] Based on the above embodiment, the separator 700 can be made of an aluminum beam. It should be noted that aluminum beams are lightweight, high-strength, corrosion-resistant, easy to process, and environmentally friendly. This can save costs while reducing the weight of the vehicle body 100, improving the vehicle 800's bending resistance in a side impact, and enhancing the force transmission path between the door 600 and the sill beam 300.

[0062] 4 , a second aspect of an embodiment of the present application provides a vehicle 800 , wherein the vehicle 800 may include the aforementioned vehicle body 100 . In one possible implementation, the vehicle 800 may further include components such as wheels 810 and a windshield 820 , which together with the vehicle body 100 constitute the vehicle 800 .

[0063] In the embodiment of the present application, in a vehicle body structure without a B-pillar, the battery mounting point is improved based on maximizing the battery volume. This ensures the side impact performance of the vehicle 800 while maximizing the use of the rocker space. This addresses the impact of a B-pillar-less vehicle body on side impact performance and the related door 600 mechanism, ensuring that the battery cells are not squeezed during a collision and meeting collision requirements. In a vehicle body 100 without a B-pillar, the addition of a third cavity 710 not only enhances the force transmission path between the door 600 and the rocker beam 300, but also takes into account the layout space of the door 600 and the rigidity of the vehicle body structure. Compared to the prior art, the combined cavity area of ​​the first cavity 310, the second cavity 410, and the third cavity 710 is larger than the cavity area of ​​the enclosed cavity in the existing rocker beam 300, enabling the vehicle 800 to better resist collision deformation and further protecting the battery body 230 in the vehicle 800.

[0064] In the embodiment of the present application, compared with the prior art, the battery mounting points are improved, and another row of battery mounting points is set on the basis of the existing row of battery mounting points. By staggering a whole row of first mounting points 211 and a whole row of second mounting points 221, when the vehicle 800 is hit from the side, the arrangement of several first mounting points 211 and several second mounting points 221 is more even, which can disperse the collision force, better resist collision deformation, and protect the battery body 230. In addition, the cavity strength of the third cavity 710, the first cavity 310 and the second cavity 410 transmits force from weak to strong, wherein the third cavity 710 and the first cavity 310 absorb energy and deform, and the second cavity 410 resists deformation, which better protects the battery body 230 from collision and extrusion, thereby improving the safety of the battery body 230 and the vehicle 800.
