[0046] 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 protection scope of this application.

[0047] Embodiments of this application provide a vehicle body structure, which may be the floor structure of the vehicle body, such as... Figure 1 and Figure 2As shown, the vehicle body structure includes a body body 10 and a sill beam 3, which is inserted into the body body 10. At least a portion of the sill beam 3 is inserted into the body body 10, or at least a portion of the body body 10 is inserted into the sill beam. By directly inserting the sill beam 3 into the body body 10, the use of a sealing plate between the sill beam 3 and the body body 10 is reduced, thereby reducing the number of components in the body floor assembly. This helps to reduce the number of water inlet pipes between components, thus improving the sealing performance of the vehicle body.

[0048] In some embodiments, the vehicle body 10 includes a front compartment assembly 1 and a rear floor assembly 2, with a door sill beam 3 inserted into at least one of the front compartment assembly 1 and the rear floor assembly 2.

[0049] In a specific implementation, the sill beam 3 includes a section along the width direction of the vehicle body, as shown in the image below. Figure 3 As shown in the Y direction, a first sill beam 31 and a second sill beam 32 are arranged at intervals. One end of the first sill beam 31 is inserted into the left side of the front compartment assembly 1, and the other end is inserted into the left side of the rear floor assembly 2. One end of the second sill beam 32 is inserted into the right side of the front compartment assembly 1, and the other end is inserted into the right side of the rear floor assembly 2. The first sill beam 31, the second sill beam 32, the front compartment assembly 1, and the rear floor assembly 2 form four overlapping areas, and correspondingly, water ingress paths are formed at the four overlapping areas. Therefore, it is only necessary to ensure the sealing performance of the four overlapping areas, thereby reducing the water ingress paths and effectively improving the sealing performance of the vehicle body.

[0050] In some embodiments, the sill beam assembly is made of extruded aluminum alloy. The sill beam assembly includes a one-piece molded inner sill plate, an aluminum profile, and a sill reinforcement plate. By designing the sill beam assembly as a one-piece structure, the number of parts is reduced, thereby reducing mold development costs. During welding and installation, the use of fixtures can be reduced, saving labor time and contributing to weight reduction.

[0051] In some embodiments, such as Figures 1 to 3 As shown, the sill beam 3 includes a main body 35, which has at least one of an insertion part 33 or an insertion groove 101. The vehicle body 10 has the other of the insertion groove 101 and the insertion part 33, and the insertion part 33 is inserted into the insertion groove 101. Taking the example where the main body 35 of the sill beam 3 has an insertion part 33 and the vehicle body 10 has an insertion groove 101, the insertion part 33 of the sill beam 3 is inserted into the insertion groove 101, so that a part of the sill beam 3 is embedded in the vehicle body 10, which helps to improve the sealing performance between the two.

[0052] The insertion part 33 is a protruding or recessed structure extending along the width direction on the sill beam 3, so that the insertion part 33 is suitable for insertion with the body body 10.

[0053] In one specific embodiment, both the first sill beam 31 and the second sill beam 32 include a main body 35 and a connector 33 connected to the front end of the main body 35. The main body 35 extends along the length of the vehicle body, and the connector 33 at the front end of the main body 35 is connected to the inner side of the main body 35. A connector groove 101 is provided on the left side of the front compartment assembly 1, and the connector 33 at the front end of the first sill beam 31 is inserted into the connector groove 101 on the left side of the front compartment assembly 1. Specifically, the connector 33 at the front end of the first sill beam 31 is inserted into the connector groove 101 on the left side of the front compartment assembly 1 along the width direction of the vehicle body. A connector groove 101 is also provided on the right side of the front compartment assembly 1, and the connector 33 at the front end of the second sill beam 32 is inserted into the connector groove 101 on the right side of the front compartment assembly 1. The connector 33 at the front end of the second sill beam 32 is inserted along the width direction of the vehicle body, as shown in the figure. Figure 3 As shown in the Y direction, it is inserted into the insertion slot 101 on the right side of the front compartment assembly 1.

[0054] The first sill beam 31 and the second sill beam 32 also include a connector 33 connected to the rear end of the main body 35, and the connector 33 located at the rear end of the main body 35 is connected to the inner side of the main body 35. A connector groove 101 is provided on the left side of the rear floor assembly 2, and the connector 33 at the rear end of the first sill beam 31 is inserted into the connector groove 101 on the left side of the rear floor assembly 2. Specifically, the connector 33 at the rear end of the first sill beam 31 is inserted into the connector groove 101 on the left side of the rear floor assembly 2 along the width direction of the vehicle body. A connector groove 101 is also provided on the right side of the rear floor assembly 2, and the connector 33 at the rear end of the second sill beam 32 is inserted into the connector groove 101 on the right side of the rear floor assembly 2. The connector 33 at the rear end of the second sill beam 32 is inserted into the connector groove 101 on the right side of the rear floor assembly 2 along the width direction of the vehicle body.

[0055] By inserting the front end of the main body 35 of the first sill beam 31 into the insertion slot 101 on the left side of the front compartment assembly 1, inserting the rear end of the main body 35 of the first sill beam 31 into the insertion slot 101 on the left side of the rear floor assembly 2, inserting the front end of the main body 35 of the second sill beam 32 into the insertion slot 101 on the right side of the front compartment assembly 1, and inserting the rear end of the main body 35 of the second sill beam 32 into the insertion slot 102 on the right side of the rear floor assembly 2, a front and rear end insertion structure is formed between the vehicle body 10 and the two sill beams 3, thereby improving the sealing performance between the vehicle body 10 and the two sill beams 3.

[0056] The insertion part 33 is inserted into the insertion groove 101 along the width direction of the vehicle body. It is understood that the first sill beam and the second sill beam are both arranged on both sides of the front compartment assembly 1 and / or the rear floor assembly 2 along the width direction of the vehicle body. Inserting the insertion part 33 into the insertion groove 101 along the width direction of the vehicle body ensures that the insertion force between the sill beam and the front compartment assembly 1 and / or the rear floor assembly 2 is perpendicular to the extension direction of the main body 35 of the sill beam 3. When the fixation of the main body 35 of the sill beam 3 becomes loose, the cooperation between the insertion part 33 and the insertion groove 101 will not be affected.

[0057] In some embodiments, such as Figure 3 and Figure 4 As shown, the insertion part 33 includes a first insertion wall 331 extending from the main body part 35. The first insertion wall 331 abuts against the groove wall of the insertion groove 101. By inserting the first insertion wall 331 into the insertion groove 101 and abutting against the groove wall of the insertion groove 101, a stable sealed connection is formed between the insertion part 33 of the sill beam 3 and the vehicle body 10.

[0058] The first insertion wall 331 is inclined relative to the horizontal plane of the vehicle body. By setting the first insertion wall 331 as an inclined structure, an inclined force is formed between the first insertion wall 331 and the groove wall of the insertion groove 101. This inclined force can be decomposed into a force in the width direction of the vehicle body and a force in the height direction of the vehicle body, thereby effectively preventing the impact on the sealing performance between the first insertion wall 331 and the groove wall of the insertion groove 101 when the vehicle body shakes.

[0059] In some embodiments, to further improve the sealing performance between the first insertion wall 331 and the groove wall of the insertion slot 101, the first insertion wall 331 is fixed to the groove wall of the insertion slot 101, thereby forming a stable sealed connection between the sill beam 3 and the vehicle body 10 along the extension direction of the first insertion wall 331, and making it difficult for the sill beam 3 and the vehicle body 10 to loosen. The extension direction of the first insertion wall 331 includes the width direction of the vehicle body and the height direction of the vehicle body. The first insertion wall 331 and the groove wall of the insertion slot 101 can be fixed by bolts and at least one of bolts, or by a snap-fit ​​structure.

[0060] The insertion part 33 also includes a second insertion wall 332, which is bent and connected to the first insertion wall 331 and is disposed opposite to the main body part 35. The second insertion wall 332 abuts against the groove wall of the insertion slot 101.

[0061] By bending the first insertion wall 331 and the second insertion wall 332 of the insertion part 33 to abut against the two adjacent groove walls of the insertion groove 101, a multi-faceted abutment is formed between the insertion part 33 and the insertion groove 101. This helps to improve the stability of the connection between the insertion part 33 and the insertion groove 101, while also improving the sealing performance between the sill beam 3 and the body body 10.

[0062] In some embodiments, to further improve the sealing performance between the second insertion wall 332 and the groove wall of the insertion slot 101, the second insertion wall 332 is fixed to the groove wall of the insertion slot 101, thereby forming a stable sealed connection between the sill beam 3 and the vehicle body 10 along the extension direction of the second insertion wall 332, and making it difficult for the sill beam 3 and the vehicle body 10 to loosen. The extension direction of the second insertion wall 332 includes the height direction of the vehicle body. The second insertion wall 332 and the groove wall of the insertion slot 101 can be fixed by bolts and at least one of bolts, or by a snap-fit ​​structure.

[0063] In some embodiments, the insertion portion 33 further includes a third insertion wall 333 opposite to the first insertion wall 331 in the height direction of the vehicle body, and the third insertion wall is connected between the main body portion 35 and the second insertion wall 332. By constructing the first insertion wall 331, the second insertion wall 332, the third insertion wall 333 and the main body portion 35 into a closed connection structure, while maintaining the rigid structure of the insertion portion 33 of the sill beam 3, the internal cavity of the insertion portion 33 can also be designed to reduce weight, which is beneficial to the lightweight design of the vehicle body. A portion of the third insertion wall 333 can abut against the groove wall of the insertion slot 101.

[0064] In some embodiments, both the main body 35 and the connecting portion 33 of the sill beam 3 are hollow structures to facilitate weight reduction of the vehicle body. Multiple reinforcing ribs 37 are provided within both the main body 35 and the connecting portion 33 to enhance their structural strength. The connecting portion 33 has a first surface 334 and a second surface 335 arranged opposite each other along the vehicle width direction. The two ends of the reinforcing ribs 37 are connected to the first surface 334 and the second surface 335 respectively to improve the structural strength of the connecting portion 33.

[0065] In some embodiments, such as Figure 5 As shown, to facilitate the insertion of the sill beam 3 into the front cabin assembly 1 and the rear floor assembly 2, a first guide portion 34 is provided on the main body 35, and a second guide portion 102 is provided on the front cabin assembly 1 and the rear floor assembly 2. The first guide portion 34 slides against the second guide portion 102. By providing the first guide portion 34 and the second guide portion 102, it is beneficial to quickly install the sill beam 3 into the front cabin assembly 1 or the rear floor assembly 2 when they are fitted together.

[0066] The first guide portion 34 is configured as a protrusion extending along the vehicle width direction, and the thickness of the first guide portion 34 gradually decreases along the vehicle width direction.

[0067] In a specific implementation, such as Figure 6 As shown, the first guide portion 34 has a first guide surface 341, which is inclined relative to the horizontal plane of the vehicle body. The second guide portion 102 has a second guide surface 103, which is inclined relative to the horizontal plane of the vehicle body to fit the first guide surface 341.

[0068] By setting up a sloping guide structure, the first guide part 34 and the second guide part 102 gradually fit together during the assembly process. Even if there are precision problems in the mating surfaces between the two, resulting in gaps or interference, the design of the sloping guide structure can still complete the mating and overlapping between the two.

[0069] The thickness of the first guide portion 34 gradually decreases along the width direction of the vehicle body, and correspondingly, the thickness of the second guide portion 102 gradually decreases along the direction from the guide portion 34 to the main body portion 35, so as to facilitate the overlapping between the two.

[0070] In some embodiments, such as Figure 2 As shown, the sill beam 3 includes a first abutment portion 36, and both the front compartment assembly 1 and the rear floor assembly 2 include a second abutment portion 104. The first abutment portion 36 and the second abutment portion 104 abut against each other along the length of the vehicle body.

[0071] By constructing the sill beam 3 to abut against the front compartment assembly 1 or the rear floor assembly 2 in the length direction of the vehicle body, the length direction of the vehicle body is as follows: Figure 1 The X direction shown, and the sill beam 3 and the front compartment assembly 1 or the rear floor assembly 2 are configured to be inserted along the Y direction of the vehicle body, thereby forming a stable connection between the sill beam 3 and the front compartment assembly 1 or the rear floor assembly 2.

[0072] In one specific implementation, the first abutment portion 36 includes a side beam disposed on the inner side of the main body portion 35, and the second abutment portion 104 includes a side beam disposed on the inner side of the front compartment assembly 1 or the rear floor assembly 2. The first abutment portion 36 overlaps the second abutment portion 104, and the end of the first abutment portion 36 abuts against the end of the second abutment portion 104 along the length direction of the vehicle body.

[0073] The first abutment portion 36 and the second abutment portion 104 are provided with a fitting gap, which helps to improve the gap or interference between the sill beam 3 and the front cabin assembly 1 or the rear floor assembly 2 caused by the precision of the parts. The fitting gap is designed to facilitate quick installation between the two. In order to improve the sealing performance between the sill beam 3 and the front cabin assembly 1 or the rear floor assembly 2, a sealant is provided at the fitting gap between the first abutment portion 36 and the second abutment portion 104.

[0074] In one embodiment, the sill beam 3 is secured to the front cabin assembly 1 or the rear floor assembly 2 by at least one of bolts and screws.

[0075] In one specific embodiment, such as Figure 7 As shown, since the front compartment assembly 1 is subjected to more collision conditions than the rear floor assembly 2, the sill beam 3 and the front compartment assembly 1 are mostly connected by bolts. The fixing strength of bolt connection is higher than that of screw connection. The sill beam 3 and the rear floor assembly 2 can mostly be connected by screws. The strength of screw connection is lower, but it is easy to install and helps to improve installation efficiency.

[0076] This application also provides an installation method for a sill beam between the front compartment assembly 1 or the rear floor assembly 2. This installation method includes pushing the sill beam in at a 45° upward angle, causing the overlapping edge of the sill beam 3 to align with the front compartment assembly 1 or the rear floor assembly 2. A clamp is used for positioning, aligning the sill beam 3 with the front compartment assembly 1 or the rear floor assembly 2 along the length of the vehicle body. Then, the insertion part of the sill beam is inserted into the insertion groove of the front compartment assembly 1 or the rear floor assembly 2 along the width of the vehicle body, thus achieving a proper fit between the sill beam and the front compartment assembly 1 or the rear floor assembly 2. This installation method avoids gaps at the overlap between the sill beam and the front compartment assembly 1 or the rear floor assembly 2 due to molding precision issues, which could affect sealing. This installation method also improves the problem of interference between the sill beam 3 and the front compartment assembly 1 or the rear floor assembly 2 along the width of the vehicle body, which could lead to assembly difficulties.

[0077] In some embodiments, such as Figure 8 As shown, the front compartment assembly 1 includes an integrally formed front bulkhead 11, front longitudinal beam 12 and front wheel arch 13. The front longitudinal beam 12 includes two parts: the front end of the front longitudinal beam and the rear end of the front longitudinal beam. The front compartment assembly 1 is formed by an integral die casting process, which reduces the number of parts, reduces mold development costs, effectively reduces the use of installation fixtures, saves time and costs, and is also conducive to achieving lightweight design of the vehicle body.

[0078] In some embodiments, such as Figure 9As shown, the rear floor assembly 2 includes a one-piece molded rear floor 21 and a rear longitudinal beam 22. The rear floor 21 includes a rear floor front crossbeam, a rear floor panel, and a rear floor rear crossbeam. The rear longitudinal beam 22 includes a front section and a rear section. The rear floor assembly 2 is molded using a one-piece die-casting process, which reduces the number of parts, reduces mold development costs, effectively reduces the use of installation fixtures, saves labor time and costs, and also facilitates lightweight vehicle body design.

[0079] According to a first aspect of this application, a sill beam assembly is provided, the sill beam assembly including a sill beam, at least a portion of the sill beam being inserted into a vehicle body, or at least a portion of the vehicle body being adapted to be inserted into the sill beam.

[0080] By inserting the sill beam into the vehicle body, the use of the sealing plate between the sill beam and the vehicle body is reduced, thereby reducing the number of parts in the vehicle body. This helps to reduce the water ingress path at the connection of parts, reduce the risk of water ingress into the vehicle body, and thus improve the sealing performance of the vehicle body.
