[0024] Reference below Figure 1-Figure 3 A vehicle frame 100 according to an embodiment of the first aspect of the present invention will be described.

[0025] like Figure 1-Figure 3 As shown, the vehicle frame 100 according to the first embodiment of the present invention comprises a floor 1, a cross beam and a plurality of sub-beams 3. In the description of the present invention, "plurality" means two or more.

[0026] Specifically, a portion of the floor 1 is raised in a direction away from the ground to form a raised portion 11. The arc-shaped crossbeam 2 is provided on the raised portion 11, and the arc-shaped crossbeam 2 extends along the width direction of the floor 1 (for example, Figure 1 The curved crossbeam 2 extends in the left-right direction (in the horizontal direction), and both ends of the curved crossbeam 2 are connected to the floor panel 1. Multiple sub-beams 3 are located on either side of the raised portion 11 in the width direction of the floor panel 1. Each sub-beam 3 is connected to the floor panel 1 and the curved crossbeam 2 at both ends, and each sub-beam 3 extends obliquely along the width direction of the floor panel 1. Each sub-beam 3 and the floor panel 1 together define an airflow channel 31, and the curved crossbeam 2, floor panel 1, and sub-beams 3 together define a wire hole 32.

[0027] For example, in Figure 1-Figure 3In the example, both ends of the curved crossbeam 2 are connected to the floor 1, ensuring a secure connection of the curved crossbeam 2 to the floor 1. A raised portion 11 is formed below the curved crossbeam 2 along the width of the floor 1 to facilitate the connection between the raised portion 11 and the curved crossbeam 2, further enhancing the secure connection of the curved crossbeam 2 to the floor 1. The raised portion 11 supports the curved crossbeam 2, preventing deformation during use. This ensures the structural integrity of the curved crossbeam 2 while creating a clearance space (referring to the internal space enclosed by the curved crossbeam 2 and the floor) between the curved crossbeam 2 and the floor 1, facilitating the formation of the airflow channel 31 and the wire hole 32.

[0028] In addition, compared to conventional straight beams, the curved beam 2 helps improve the load-bearing capacity of the frame 100. The sub-beams 3 can further enhance the load-bearing capacity of the curved beam 2, thereby improving the structural reliability of the frame 100. Multiple sub-beams 3 are provided on both sides of the raised portion 11. Along the width direction of the floor 1, one end of each sub-beam 3 is connected to the floor 1, and the other end of each sub-beam 3 is connected to the curved beam 2. This helps improve the structural strength and bending and torsional rigidity of the curved beam 2, increases the number of force transmission paths and the force contact area between the curved beam 2 and the floor 1, reduces the risk of stress concentration in the curved beam 2, and thus improves the force uniformity and overall structural stability of the curved beam 2 and the floor 1.

[0029] The closer the avoidance space between the arc-shaped beam 2 and the floor 1 is to the position of the protrusion 11, the larger the avoidance space is in the thickness direction of the floor 1 (for example, Figure 1 Because the airflow channel 31 needs to pass through a larger cross-section, the avoidance space below is functionally divided. The avoidance space on both sides of the raised portion 11 can be used to arrange the airflow channel 31 (that is, each sub-beam 3 and the floor 1 jointly define the airflow channel 31), while the avoidance space away from the raised portion 11 can be used to arrange the wire holes 32 (that is, the arc-shaped crossbeam 2, the floor 1 and the sub-beam 3 jointly define the wire holes 32). This can effectively improve the space utilization of the avoidance space.

[0030] When subjected to side impact forces, the curved crossbeam 2 not only experiences forces along the width of the floor panel 1 but also experiences forces along its thickness, effectively enhancing the curved crossbeam's 2 side impact resistance. Consequently, the curved crossbeam 2 evenly distributes and transmits loads, reducing the risk of bending or breaking under load. This enhances the stability of the curved crossbeam and extends its lifespan. Furthermore, the curved crossbeam reduces the impact of the curved crossbeam on wiring harnesses, improving the safety factor of wiring harnesses within the wiring holes 32 during side impacts, thereby enhancing the structural reliability of the vehicle frame 100.

[0031] According to the frame 100 of the embodiment of the present invention, an air flow channel 31 and a wire hole 32 are formed between the curved crossbeam 2 and the floor 1, which improves space utilization while ensuring the structural integrity of the curved crossbeam 2, that is, meets the needs of sufficient wind passing through and the need of wiring harness routing. In addition, the provision of multiple sub-beams 3 is conducive to increasing the number of force transmission paths and the force contact area between the curved crossbeam 2 and the floor 1, reducing the risk of stress concentration in the curved crossbeam 2, thereby improving the force uniformity and overall structural stability of the curved crossbeam 2, and further improving the structural reliability and safety of the frame 100.

[0032] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 One end of each sub-beam 3 extends to the raised portion 11. This helps the sub-beam 3 share the force of the raised portion 11, thereby improving the structural stability of the raised portion 11 and preventing the raised portion 11 from being greatly deformed due to a large force during use.

[0033] Further, refer to Figure 3 Each sub-beam 3 includes a first beam section 33 and a second beam section 34, which are connected to each other. The first beam section 33 is connected to the curved crossbeam 2 and extends obliquely along the width of the floor 1. The second beam section 34 extends along the thickness of the floor 1 and is connected to the floor 1 and the curved crossbeam 2. The first beam section 33 and the floor 1 together define an airflow channel 31, and the curved crossbeam 2, the floor 1, and the second beam section 34 together define a wire hole 32. In other words, the second beam section 34 connects the floor 1 and the curved crossbeam 2 at both ends along the thickness of the floor 1. This allows the second beam section 34 to strengthen support for the curved crossbeam 2, further reducing the risk of deformation of the curved crossbeam 2 due to excessive force. One end of the first beam section 33 extends to the raised portion 11, and the other end of the first beam section 33 is connected to the second beam section 34, so as to limit the first beam section 33 through the raised portion 11 and the second beam section 34, thereby preventing the first beam section 33 from excessively moving along the extension direction, thereby improving the structural integrity and stability of the sub-beam 3.

[0034] Furthermore, refer to Figure 3The included angle between the first beam section 33 and the horizontal plane is α, where α satisfies: 8°≤α≤20°. When α is less than 8°, the angle between the first beam section 33 and the horizontal plane is small. In order to meet the size requirement of the avoidance space between the curved crossbeam 2 and the floor 1, the length of the first beam section 33 needs to be extended, which is easy to reduce the distance between the second beam section 34 and the end of the curved crossbeam 2, thereby making the size of the wire hole 32 small, making it difficult to meet the requirements of wiring harness installation. Alternatively, if the length of the first beam section 33 is fixed, the size of the airflow channel 31 will be small, making it difficult to meet the need for sufficient wind to pass through. When α is greater than 20°, the angle between the first beam section 33 and the horizontal plane is large, and the extended length of the curved crossbeam 2 is fixed. When the airflow channel 31 meets the requirements, the distance between the second beam section 34 and the curved crossbeam 2 is large, making it difficult to meet the side impact resistance of the part of the curved crossbeam 2 corresponding to the wire hole 32, and it is difficult to reduce the squeezing of the wire harness by the curved crossbeam 2, thereby reducing the safety of the wire harness. Alternatively, when the requirements of the airflow channel 31 and the wire hole 32 are met, the length of the curved crossbeam 2 is small, which is easy to reduce the bearing capacity of the curved crossbeam 2. Therefore, by setting the angle between the first beam section 33 and the horizontal plane to 8°≤α≤20°, the size of the airflow channel 31 meets the requirement of sufficient wind blowing through, and the size of the wire hole 32 meets the requirement of wiring harness routing, while increasing the structural strength and side impact resistance of the curved crossbeam 2, thereby improving the structural stability of the frame 100 and the safety of the wiring harness.

[0035] In addition, refer to Figure 3 The minimum distance L between the end of the curved crossbeam 2 and the second beam section 34 across the width of the floor 1 is specified as 150 mm ≤ L ≤ 300 mm. When L is less than 150 mm, the minimum distance between the end of the curved crossbeam 2 and the second beam section 34 across the width of the floor 1 is too small, resulting in a smaller size for the corresponding wire hole 32, making it difficult to meet wiring harness installation requirements. When L is greater than 300 mm, the minimum distance between the end of the curved crossbeam 2 and the second beam section 34 across the width of the floor 1 is too large, making it difficult to meet the side impact resistance requirements of the portion of the curved crossbeam 2 corresponding to the wire hole 32, making it difficult to reduce compression on the wiring harness, and thus reducing wiring harness safety. Therefore, by setting the minimum distance between the end of the arc-shaped crossbeam 2 and the second beam section 34 in the width direction of the floor 1 to 150mm≤L≤300mm, the size of the wire hole 32 meets the requirements of the wiring harness installation, while improving the side collision resistance of the part of the arc-shaped crossbeam 2 corresponding to the wire hole 32, reducing the squeezing of the arc-shaped crossbeam 2 on the wiring harness, etc., thereby improving the safety of the wiring harness.

[0036] According to some specific embodiments of the present invention, Figure 3The height of the raised portion 11 in the thickness direction of the floor 1 is H, where H satisfies the following conditions: 40 mm ≤ H ≤ 80 mm. When H is less than 40 mm, the height of the raised portion 11 in the thickness direction of the floor 1 is relatively small, and the corresponding distance between the curved crossbeam 2 and the floor 1 is relatively small. This makes it difficult to meet the required dimensions of the airflow channel 31 and / or the wire hole 32 within the limited width of the floor 1. When H is greater than 80 mm, the height of the raised portion 11 in the thickness direction of the floor 1 is relatively large. While meeting the required dimensions of the airflow channel 31 and the wire hole 32, it also reduces the extended length of the curved crossbeam 2, lowering its bearing capacity and concentrating the force on the curved crossbeam 2. This can easily cause significant deformation of the curved crossbeam 2, shortening the service life of the vehicle frame 100. Therefore, by setting the height of the raised portion 11 in the thickness direction of the floor 1 to 40mm≤H≤80mm, while ensuring that the sizes of the air flow channel 31 and the wire hole 32 meet the requirements, the extended length of the arc-shaped crossbeam 2 is relatively reasonable, which can meet the bearing capacity requirements of the arc-shaped crossbeam 2, avoid large deformation of the arc-shaped crossbeam 2, and extend the service life of the frame 100.

[0037] According to some embodiments of the present invention, referring to Figure 3 The arc-shaped crossbeam 2 includes a first connecting section 21 and two second connecting sections 22. The first connecting section 21 is fitted with the raised portion 11. The two second connecting sections 22 are connected to both ends of the first connecting section 21, and each second connecting section 22 extends obliquely in a direction away from the first connecting section 21 and is connected to the floor 1. The side surface of the raised portion 11 facing the arc-shaped crossbeam 2 is adapted to the first connecting section 21, thereby increasing the connection area between the first connecting section 21 and the raised portion 11 and improving the connection stability and reliability between the arc-shaped crossbeam 2 and the raised portion 11. The two second connecting sections 22 are obliquely connected to the first connecting section 21 and the floor 1, so that the force on the first connecting section 21 can be dispersed and transmitted to the floor 1 through the second connecting section 22, thereby improving the structural strength and stability of the arc-shaped crossbeam 2 and extending the service life of the arc-shaped crossbeam 2.

[0038] Further, refer to Figure 1 and Figure 3 The width of the raised portion 11 in the width direction of the floor panel 1 gradually increases as it moves away from the curved cross-member 2. This helps to further disperse and transmit the force applied to the first connecting section 21 connected to the raised portion 11 to the floor panel 1, improving the raised portion 11's ability to disperse the force applied to the curved cross-member 2. This allows the curved cross-member 2 to better adapt to and resist stress concentration caused by loads on the side away from the raised portion 11, thereby improving the structural stability of the vehicle frame 100.

[0039] According to some specific embodiments of the present invention, each sub-beam 3 is a hollow beam, which is beneficial to maintaining the structural strength and rigidity of the sub-beam 3 while reducing the weight of the sub-beam 3, saving materials and improving economic benefits.

[0040] The cross-section of each sub-beam 3 may be in the shape of a circular ring or a rectangular ring, but is not limited thereto.

[0041] Reference Figure 3 , the thickness of each sub-beam 3 is d, where d satisfies: 1mm≤d≤3mm. When d<1mm, the thickness of each sub-beam 3 is small, the structural strength of the sub-beam 3 is small, and the sub-beam 3 is easily deformed or broken during use, which reduces the service life of the frame 100; when d>3mm, the thickness of each sub-beam 3 is large, which increases the weight of the sub-beam 3 and is not conducive to the lightweight design of the frame 100. Therefore, by setting the thickness of each sub-beam 3 to 1mm≤d≤3mm, the thickness design of the sub-beam 3 is made more reasonable, that is, while ensuring the structural strength of the sub-beam 3, it is conducive to the lightweight design of the sub-beam 3, and thus is conducive to the lightweight design of the frame 100.

[0043] The vehicle according to the embodiment of the present invention adopts the above-mentioned frame 100, which is conducive to improving the user experience, while improving the layout regularity and safety of the wiring harness, etc., which is conducive to improving the market competitiveness of the vehicle.
