Description

Technical Field

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

[0002] In recent years, my country's automotive industry has developed rapidly, and it remains a core industry for future development. With continuous technological advancements and rising living standards, the demand for automotive performance is increasing. Among the structural elements of a car is the B-pillar, located between the front and rear doors. The B-pillar's primary function is to withstand side impacts, ensuring the safety of occupants and supporting the overall vehicle structure.

[0003] However, to improve ease of entry and exit and provide a better riding experience, the development of a pillarless body has become a new trend in vehicle development. This allows users to sit directly inside the car instead of crawling in, while also expanding the usability of the seats, supporting 180° rotation, and creating an office and home-like feel throughout the vehicle. At the same time, the door opening size will be more than twice that of current models on the market. Therefore, ensuring the vehicle's safety performance is crucial in the context of a pillarless design.

[0004] However, in most current automobiles, the door sill and battery are typically connected by a single bolt. With a pillarless body structure, the battery intrudes more into the structural space of the vehicle body, and the requirements for battery collision safety are higher. Battery protection and the development of vehicle safety performance have become one of the major technical challenges hindering the development of pillarless bodies, thus restricting the mass production of such vehicles. The structural changes brought about by developing a pillarless body, especially the weakening of the door sill's force-transmitting structure and the reduction in space, lead to a decrease in collision safety performance and battery deformation due to compression. Therefore, the structure needs further research and improvement to meet the requirements of automotive evaluation regulations. Summary of the Invention

With a pillarless body structure, the battery intrudes more into the structural space of the vehicle body, and the battery's collision safety requirements are higher. Battery protection and the development of vehicle safety performance have become significant technical challenges hindering the mass production of pillarless bodies. The development of pillarless bodies leads to structural changes, particularly a weakening of the door sill's force-transmitting structure and a reduction in its placement space, resulting in decreased collision safety performance and battery deformation under pressure.

[0054] As described in the background section, in most current automobiles, the door sill and battery are typically connected by a single bolt. With a pillarless body structure, the battery intrudes more into the structural space of the vehicle body, and the requirements for battery collision safety are higher. Battery protection and the development of vehicle safety performance have become one of the major technical challenges hindering the development of pillarless bodies, thus restricting the mass production of such vehicles. The structural changes brought about by developing a pillarless body, especially the weakening of the door sill's force-transmitting structure and the reduction in its placement space, lead to a decrease in collision safety performance and battery deformation due to compression. Therefore, the structure needs further research and improvement to meet the requirements of automotive evaluation regulations.

[0055] To address the aforementioned technical problems, this application provides a vehicle body and a vehicle, the vehicle body including a battery pack, a sill beam, and a floor longitudinal beam. The battery pack has a first mounting portion and a second mounting portion on the side facing the sill beam. One end of the battery pack is connected to the sill beam via the first mounting portion, and the other end of the battery pack is connected to the floor longitudinal beam via the second mounting portion. The vehicle includes the aforementioned vehicle body. Thus, this application embodiment improves the battery mounting point based on maximizing battery volume in a pillarless body structure, ensuring side impact performance while maximizing the use of sill space. It resolves the impact of a pillarless body structure on side impact performance and related door mechanisms, ensuring that the battery cells are not compressed during a collision, meeting domestic and international collision requirements.

[0056] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0057] Figure 1 This is a partial structural diagram of a vehicle body 100. (Refer to...) Figure 1 As shown, the vehicle body 100 may include a door 600 and a sill beam 300. Due to its structural characteristics, the sill beam 300 can be composed of several crossbeams 31 and longitudinal beams 32, so that the sill beam 300 can form a closed space 33 through the crossbeams 31 or longitudinal beams 32. Therefore, the sill beam 300 can have a closed cavity 33.

[0058] However, Figure 1The vehicle body 100 shown 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 characteristics compared to the vehicle body 100 with a B-pillar. When the side of the vehicle body 100 is hit by a collision, the force transmission path of the closed cavity 33 of the sill beam 300 is relatively simple, which may not be able to resist the collision deformation well and cannot protect the battery cells inside the vehicle.

[0059] To address the aforementioned issues, this application provides a vehicle body and a vehicle with a pillarless body structure. Based on maximizing battery volume, the battery mounting point has been improved, ensuring the vehicle's side impact performance while maximizing the use of the sill space. The specific structure of the vehicle body and vehicle provided in this application embodiment is described below with reference to the accompanying drawings.

[0060] refer to Figure 2 A first aspect of this application provides a vehicle body 100, which may include a battery assembly 200, a sill beam 300, and a floor longitudinal beam 400. The sill beam 300 may be located on one side of the floor longitudinal beam 400, and the sill beam 300 and the floor longitudinal beam 400 may form the frame of the vehicle body 100. In this embodiment, the side of the battery assembly 200 facing the sill beam 300 may have a first mounting portion 210, and correspondingly, the side of the battery assembly 200 facing the floor longitudinal beam 400 may have a second mounting portion 220. In one possible implementation, one end of the battery assembly 200 can be connected to the sill beam 300 via the first mounting portion 210, and the other end of the battery assembly 200 can be connected to the floor longitudinal beam 400 via the second mounting portion 220.

[0061] Continue to refer to Figure 2 In this specific implementation, the battery assembly 200 may include a battery body 230. In one possible implementation, due to the structural characteristics of the sill beam 300 and the floor longitudinal beam 400, they may be composed of several crossbeams and longitudinal beams respectively, thus the 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; this application does not limit the shape of the battery body 230. Therefore, the battery body 230 can be connected to the sill beam 300 and the floor longitudinal beam 400 by providing a first mounting portion 210 and a second mounting portion 220. In this embodiment, 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.

[0062] refer to Figure 2 as well as Figure 3Based on the above embodiments, 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, the number of first mounting points 211 and second mounting points 221 may be multiple, and this application does not limit the number of first mounting points 211 and second mounting points 221. 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, the number of first fasteners 212 and second fasteners 222 may be multiple, and this application does not limit the number of first fasteners 212 and second fasteners 222. The first fastener 212 may correspond one-to-one with the first mounting point 211, and the second fastener 222 may also correspond one-to-one with the second mounting point 221. Thus, in this embodiment, the first mounting part 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 part 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 this application does not limit the type of first fasteners and the second fasteners.

[0063] Continue to refer to Figure 3 Based on the above embodiments, a plurality of first mounting points 211 can be arranged side by side along the length of the battery body 230, and correspondingly, a plurality of second mounting points 221 can also be arranged side by side along the length of the battery body 230. In this way, a plurality of first mounting points 211 can form a row, and a plurality of second mounting points 221 can also form a row. The plurality of first mounting points 211 and a plurality of second mounting points 221 make the connection of the battery body 230 more stable and improve the connection rigidity between the battery body 230 and the vehicle body 100.

[0064] Continue to refer to Figure 3 Based on the above embodiments, a plurality of first mounting points 211 and a plurality of second mounting points 221 can be staggered in the width direction of the battery body 230. It is understood that at least some of the projections of the second mounting points 221 toward the first mounting points 211 do not overlap with the first mounting points 211. In this way, by staggering a whole row of first mounting points 211 and a whole row of second mounting points 221, when the vehicle 800 is involved in a side collision, the arrangement of the first mounting points 211 and the second mounting points 221 is more uniform, which can disperse the impact force, better resist collision deformation, and protect the battery body 230.

[0065] Continue to refer to Figure 2 Based on the above embodiments, the first mounting portion 210 may 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 may be located at a lower position on the sill beam 300, while the second mounting portion 220 may be located at a higher position on the floor longitudinal beam 400. This maximizes the battery volume and thus ensures the battery's range.

[0066] Continue to refer to Figure 2 Based on the above embodiments, the vehicle body 100 may further include a first cavity 310. The sill beam 300 may have a first cavity 310. Due to its structural characteristics, the sill beam 300 may be composed of several crossbeams and longitudinal beams, allowing it to form a closed space. Therefore, the sill beam 300 may have a first cavity 310. In one possible implementation of this application embodiment, one end of several first fasteners 212 may extend into the first cavity 310, and the other end of the several first fasteners 212 may be connected to a first mounting portion 210 through several 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 several first fasteners 212 passing through the several first mounting points 211.

[0067] Continue to refer to Figure 2 Based on the above embodiments, 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; however, in other embodiments, the floor 500 may have other shapes. This application does not limit the shape of the floor 500. In this embodiment, the internal space enclosed by the floor longitudinal beam 400, the floor 500, and the sill beam 300 can form a second cavity 410. Due to its structural characteristics, the floor longitudinal beam 400 may be composed of several crossbeams and longitudinal beams. In one possible implementation, one end of several second fasteners 222 may extend into the second cavity 410, and the other end of the several second fasteners 222 may be connected to the second mounting portion 220 through several 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 several second fasteners 222 passing through the several second mounting points 221.

[0068] Continue to refer to Figure 2Based on the above embodiments, the vehicle body 100 may further include a door 600 and a partition 700. The partition 700 may be located between the door 600 and the sill beam 300. In one possible implementation, there may be a certain gap between the door 600 and the sill beam 300, and the partition 700 may be located within this gap, with one side of the partition 700 connected to the sill beam 300 to fix the partition 700 to the sill beam 300. In this embodiment, when the door 600 is closed, the internal space enclosed by the door 600 and the partition 700 can form a third cavity 710. Thus, the partition 700 enhances the force transmission path between the door 600 and the sill beam 300. It is worth noting that the partition 700 and the first mounting portion 210 may be arranged side-by-side in the width direction of the vehicle body 100. When the side of the vehicle body 100 is involved in a collision, the partition 700 can resist part of the collision force on its inner first mounting part 210, thereby protecting the battery body 230 inside the vehicle body 100.

[0069] refer to Figure 2 as well as Figure 4 In this embodiment, the vehicle body 100 may have at least two doors 600, and sill beams 300 are respectively provided below each door 600. The sill beams 300 may be located on both sides in the width direction of the floor 500, so that occupants can enter the vehicle body 100 through the sill beams 300. It is understood that, compared with the closed cavity of the sill beam 300 in the prior art, the size of the first cavity 310 may be set slightly smaller than the size of the closed cavity, so as to provide some space for the size of the third cavity 710 on one side of the first cavity 310, thereby enhancing the force transmission path between the door 600 and the sill beam 300.

[0070] Based on the above embodiments, the sill 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 sill beam 300 can have a first mounting part 210 and a second mounting part 220, providing protection for both sides of the vehicle body.

[0071] Continue to refer to Figure 2Based on the above embodiments, 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 separator 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 three cavities 710, 310, and 410 are separated to form three independent cavities. In this embodiment, arranging the third cavity 710, the first cavity 310, and the second cavity 410 side by side in the width direction of the vehicle body 100 enhances the force transmission path between the door 600 and the sill beam 300 when the vehicle 800 is involved in a side collision, thereby increasing the bending resistance of the vehicle 800 in the side impact direction. The force transmission path between the door 600 and the sill 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 successively, 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.

[0072] Based on the above embodiments, the partition 700 can be made of aluminum beam. It should be noted that aluminum beam has the characteristics of being lightweight, high-strength, corrosion-resistant, easy to process, and environmentally friendly. This can save costs, reduce the internal weight of the vehicle body 100, and improve the bending resistance of the vehicle 800 in the side-impact direction. It also enhances the force transmission path between the door 600 and the sill beam 300.

[0073] refer to Figure 4 A second aspect of this application provides a vehicle 800, wherein the vehicle 800 may include the vehicle body 100 described above. In one possible implementation, the vehicle 800 may further include components such as wheels 810 and windshield 820, which together with the vehicle body 100 constitute the vehicle 800.

[0074] In this embodiment, with a pillarless body structure, the battery mounting point is improved to maximize battery volume, ensuring the side impact performance of the vehicle 800 while maximizing the use of the sill space. This addresses the impact of a pillarless body structure on side impact performance and related door 600 mechanisms, ensuring that the battery cells are not compressed during a collision, meeting domestic and international collision requirements. With the pillarless body structure, the addition of a third cavity 710 enhances the force transmission path between the door 600 and the sill beam 300, while also addressing the issues of door 600 placement space and body structure rigidity. Compared to existing technologies, the overall cavity area of ​​the first cavity 310, the second cavity 410, and the third cavity 710 is larger than the cavity area of ​​the closed cavity in the existing sill beam 300, enabling the vehicle 800 to better resist collision deformation and further protecting the battery body 230 within the vehicle 800.

[0075] In this embodiment, the battery mounting points are improved compared to the prior art by adding another row of battery mounting points on top of the existing row. By staggering the row of first mounting points 211 and the row of second mounting points 221, when the vehicle 800 is involved in a side collision, the arrangement of the several first mounting points 211 and several second mounting points 221 is more uniform, 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. The third cavity 710 and the first cavity 310 absorb energy deformation, while the second cavity 410 resists deformation, better protecting the battery body 230 from collision compression, thereby improving the safety of the battery body 230 and the vehicle 800.
