Description

Technical Field

[0006] ,

[0001] The present invention relates to the technical field of vehicles, and particularly relates to a vehicle component, a vehicle body structure and a vehicle. Background Art

[0002] The seat mounting cross member of a vehicle not only serves as a mounting support for the seat, but also serves as a key force transmission component during a side impact of the vehicle. The seat mounting cross member of the vehicle needs to have good strength and stiffness to prevent obvious deformation of the occupant compartment and the battery pack of the vehicle during a side impact of the vehicle.

[0003] Such as Figure 6 As shown, in the existing vehicle body structure, the seat mounting cross member 3 is usually a beam-shaped member with a "U" - shaped cross section, and both ends of the seat mounting cross member 3 are respectively connected to two vehicle body sill beams 4. The existing seat mounting cross member and vehicle body structure have the following technical problems:

[0004] In order to ensure the bending and torsional resistance performance of the whole vehicle, it is often necessary to design the cavity of the seat mounting cross member to be relatively large, resulting in the seat mounting cross member occupying too much vehicle body height space.

[0005] The connection part between the seat mounting cross member and the vehicle body sill beam has relatively low strength. During a side impact of the vehicle, this connection part is usually a weak point in the vehicle body structure.

[0006] By adding a reinforcing member to the seat mounting cross member, the strength of the seat mounting cross member can be improved, but it will increase the number of components and the weight of the whole vehicle, which is not conducive to the lightweight design of the vehicle.

[0007] In the existing vehicle body structure, it is usually necessary to set two seat mounting cross members to provide mounting points for a row of vehicle seats. During the manufacturing process of the vehicle, these two seat mounting cross members need to be installed separately, resulting in low manufacturing efficiency. Summary of the Invention

[0008] The purpose of the present invention is to provide a vehicle component, a vehicle body structure and a vehicle to alleviate or eliminate at least one of the above - mentioned technical problems.

[0009] A vehicle component according to the present invention is adapted to be integrally installed in a vehicle. The vehicle component includes two longitudinal beams arranged at intervals in the left - right direction and multiple cross beams arranged at intervals in the front - rear direction. All the multiple cross beams are connected between the two longitudinal beams. Connection parts are provided on both of the two longitudinal beams. The connection part on one longitudinal beam is used to connect with the sill beam on one side of the vehicle, and the connection part on the other longitudinal beam is used to connect with the sill beam on the other side of the vehicle.

[0010] Optionally, it includes two crossbeams, one of which is connected at both ends to one end of each of the two longitudinal beams, and the other of which is connected at both ends to the other ends of each of the two longitudinal beams.

[0011] Optionally, both longitudinal beams and the multiple transverse beams are hollow structures with closed cross sections.

[0012] Optionally, the vehicle component comprises an annular bottom wall, an annular top wall located above the bottom wall, an inner peripheral wall connecting the inner edge of the bottom wall and the inner edge of the top wall, and an outer peripheral wall connecting the outer edge of the bottom wall and the outer edge of the top wall.

[0013] Optionally, the vehicle component is an integral part made from a single tubular metal blank through a tube bending process and a hot air expansion forming process.

[0014] Optionally, at least one of the crossbeams comprises multiple crossbeam segments arranged sequentially, wherein the crossbeam segment closer to the middle position along the length direction of the crossbeam in two adjacent crossbeam segments has a thicker material; and adjacent crossbeam segments are connected by a material thickness transition section.

[0015] Optionally, the connecting part is disposed on the side wall of the longitudinal beam on the side closest to the vehicle, and the connecting part is provided with a first connecting hole for connecting with the sill beam.

[0016] Optionally, at least one of the crossbeams is provided with vehicle seat mounting holes.

[0017] Optionally, the vehicle component is provided with a leakage hole.

[0018] Optionally, the vehicle component is provided with positioning holes.

[0019] Optionally, the vehicle component is provided with a second connection hole for connecting to the vehicle's battery pack.

[0020] The present invention also proposes a vehicle body structure, including two sill beams and the vehicle component described in any of the above claims, wherein the two longitudinal beams of the vehicle component are respectively connected to the two sill beams.

[0021] The present invention also proposes a vehicle comprising the aforementioned body structure.

[0022] This invention helps to improve the strength and rigidity of the vehicle body, improve the side impact performance of the vehicle, and improve the manufacturing efficiency of the vehicle. While ensuring the performance of the vehicle body, it can reduce the requirements for the material thickness and cavity size of vehicle parts, and has the characteristics of fewer parts and higher material utilization.

Detailed Implementation

[0031] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] like Figure 1 and Figure 2The vehicle component 1 shown is adapted to be integrally installed in a vehicle. The vehicle component 1 includes two longitudinal beams 102 arranged at intervals in the left-right direction and multiple transverse beams 101 arranged at intervals in the front-rear direction. The multiple transverse beams 101 are all connected between the two longitudinal beams 102. Both longitudinal beams 102 are provided with connecting parts. The connecting part on one longitudinal beam 102 is used to connect with the sill beam 2 on one side of the vehicle, and the connecting part on the other longitudinal beam 102 is used to connect with the sill beam 2 on the other side of the vehicle.

[0034] Using the above technical solution, multiple crossbeams 101 and two longitudinal beams 102 are connected to form a frame structure. The frame structure has high strength and rigidity, which helps to improve the strength and rigidity of the vehicle body. Moreover, the frame structure can be installed as a whole, which helps to improve the manufacturing efficiency of the vehicle.

[0035] The aforementioned vehicle component 1 is connected to the sill beam 2 via the longitudinal beam 102. The longitudinal beam 102 and the sill beam 2 can form a large force transmission area, which can better transmit the side impact force, thereby improving the vehicle's side impact performance.

[0036] The aforementioned vehicle component 1 can serve as a seat mounting crossbeam. When vehicle component 1 serves as a seat mounting crossbeam, it effectively solves the problem of weak performance at the connection between the seat mounting crossbeam and the sill beam in the prior art.

[0037] In some embodiments, the vehicle component 1 includes two crossbeams 101, one of which is connected at both ends to the front ends of two longitudinal beams 102, and the other of which is connected at both ends to the rear ends of two longitudinal beams 102. The two crossbeams 101 and two longitudinal beams 102 can be connected to form a ring-shaped vehicle component 1, which has the characteristics of simple structure and easy implementation.

[0038] In some embodiments, the two longitudinal beams 102 and the multiple transverse beams 101 are all hollow structures with closed cross sections. Compared to transverse beams with a "U"-shaped cross section, the rigidity of the hollow transverse beams 101 with closed cross sections is significantly improved, which can greatly enhance the bending and torsional resistance of vehicle component 1, thereby improving the bending and torsional resistance of the entire vehicle.

[0039] Furthermore, by employing a closed-section and hollow crossbeam 101, on the one hand, the material thickness of the crossbeam 101 can be significantly reduced while ensuring the vehicle's bending and torsional resistance, thus contributing to the vehicle's lightweight design. On the other hand, while maintaining the vehicle's bending and torsional resistance, the cavity of the crossbeam 101 can be made smaller, thereby allowing the crossbeam 101 to be made thinner, which reduces the space occupied by the crossbeam 101 in the vehicle's height.

[0040] In some embodiments, such as Figure 3As shown, vehicle component 1 comprises an annular bottom wall 116, an annular top wall 115 located above the bottom wall 116, an inner peripheral wall 113 connecting the inner edge of the bottom wall 116 and the inner edge of the top wall 115, and an outer peripheral wall 114 connecting the outer edge of the bottom wall 116 and the outer edge of the top wall 115. Using the above technical solution, vehicle component 1 has a hollow annular structure, and the cross-section of vehicle component 1 is approximately rectangular, which better provides support and mounting points for the vehicle's seats and battery pack.

[0041] In some embodiments, vehicle component 1 is an integral part manufactured from a single tubular metal blank through a tube bending process and a hot air expansion forming process. By combining the tube bending process and the hot air expansion forming process, a ring-shaped and hollow vehicle component 1 can be manufactured, which features a small number of parts and high material utilization. In specific implementations, the material utilization rate can reach over 85%.

[0042] In some embodiments, thermoforming materials can be used to manufacture vehicle component 1 to ensure the strength performance of vehicle component 1, further reduce the material thickness of vehicle component 1, and help reduce the weight of vehicle component 1.

[0043] In a specific implementation, the vehicle component 1, made from a single tubular metal blank, is a ring-shaped integral frame structure, and the joints at the ends of the vehicle component 1 can be connected by welded parts 112. As a preferred example, the joints at the ends of the vehicle component 1 can be laser-welded to form welded parts 112 after bending the tube and before hot-air expansion molding.

[0044] In some embodiments, at least one crossbeam 101 includes multiple crossbeam segments 103 arranged sequentially, with the crossbeam segment 103 closer to the middle of the crossbeam 101 along its length having a thicker material. By adopting the above technical solution and rationally setting the material thickness of each crossbeam segment 103 of the crossbeam 101, the weight of the vehicle component 1 can be reduced while ensuring that the crossbeam 101 uniformly transmits lateral impact forces. Furthermore, setting the material thickness of the crossbeam segment 103 near the end of the crossbeam 101 to be thinner reduces the difficulty of bending the tubular metal blank, thus helping to reduce the processing difficulty of the vehicle component 1. Typically, the material thickness of the crossbeam segment 103 at the end of the crossbeam 101 is the same as the material thickness of the longitudinal beam 102 connected to that end.

[0045] Furthermore, adjacent crossbeam segments 103 are connected by a material thickness transition section 104. The material thickness transition section 104 helps ensure the uniform transmission of lateral impact forces. In specific implementation, to ensure the structural performance of the material thickness transition section 104, its length in the longitudinal direction of the crossbeam 101 is not less than 100 times the difference in material thickness between the two crossbeam segments 103 on either side of the material thickness transition section 104.

[0046] In practice, vehicle parts 1 can be made from tubular metal blanks of varying thicknesses. Multiple crossbeam sections 103 of varying thicknesses and thickness transition sections 104 of gradually changing thickness can be formed using tubular metal blanks of varying thicknesses.

[0047] In some embodiments, the connecting portion is disposed on the side wall of the longitudinal beam 102 on the outer side of the vehicle, and the connecting portion is provided with a first connecting hole 106 for connecting with the sill beam 2. By disposing the connecting portion on the side wall of the longitudinal beam 102 on the outer side of the vehicle, a larger force transmission area can be formed between the longitudinal beam 102 and the sill beam 2.

[0048] In practical implementation, the first connecting hole 106 is used to cooperate with the first bolt, and the first bolt can be used to fix the side wall of the longitudinal beam 102 on the outside of the vehicle to the sill beam 2 together.

[0049] In practice, multiple first connection holes 106 can be provided on the side wall of the longitudinal beam 102 on the side facing outwards from the vehicle.

[0050] As a preferred example, to ensure a large force transmission area between the longitudinal beam 102 and the sill beam 2, the side wall of the longitudinal beam 102 on the outside of the vehicle and the side wall of the sill beam 2 on the inside of the vehicle are stacked and fixedly connected together. By using the side wall of the longitudinal beam 102 on the outside of the vehicle to increase the force transmission area between the vehicle component 1 and the sill beam 2, the vehicle body's ability to resist side impacts can be significantly improved.

[0051] In some embodiments, at least one crossbeam 101 is provided with vehicle seat mounting holes 105. The crossbeam 101 of the vehicle component 1 can serve as a seat mounting crossbeam, providing support and mounting points for the vehicle seat. More specifically, the two crossbeams 101 of the vehicle component 1 can serve as a front seat mounting crossbeam and a rear seat mounting crossbeam, respectively.

[0052] By adopting the above technical solution, a single vehicle component 1 can replace the six parts in the prior art: the front seat mounting crossbeam, the rear seat mounting crossbeam, the left bracket of the front seat mounting crossbeam, the right bracket of the front seat mounting crossbeam, the left bracket of the rear seat mounting crossbeam, and the right bracket of the rear seat mounting crossbeam. This reduces the number of parts, tooling quantity, and tooling costs.

[0053] In specific implementation, a first clearance hole 107 is usually provided on the inner peripheral wall 113 of the vehicle component 1, which is opposite to the first connecting hole 106. The first clearance hole 107 is used to avoid the first bolt and provide an installation channel for the first bolt.

[0054] In some embodiments, the vehicle component 1 is provided with a drain hole 111. Providing the drain hole 111 can ensure the quality of electrophoresis inside the vehicle component 1.

[0055] In some embodiments, the vehicle component 1 is provided with a positioning hole 110, which can play a positioning role and improve the installation accuracy of the vehicle component 1.

[0056] In some embodiments, the vehicle component 1 is provided with a second connection hole 109 for connecting to the vehicle's battery pack. The second connection hole 109 provides a fixing point for the battery pack. In specific implementations, a second bolt that mates with the second connection hole 109 can be used to securely connect the battery pack and the vehicle component 1. More specifically, the second connection hole 109 is typically provided on the bottom wall 116 of the vehicle component 1, and a second clearance hole 108 opposite to the second connection hole 109 is typically provided on the top wall 115 of the vehicle component 1. The second clearance hole 108 is used to avoid the second bolt and provides an installation channel for the second bolt.

[0057] As a specific example, vehicle component 1 includes two crossbeams 101 and two longitudinal beams 102. The lengths of the two crossbeams 101 extend in the left-right direction, and the lengths of the two longitudinal beams 102 extend in the front-back direction. The two crossbeams 101 and the two longitudinal beams 102 are connected to form a ring-shaped rectangular frame structure. The corner portion between the crossbeams 101 and the longitudinal beams 102 is a bent section 117 formed by bending. More specifically, the material thickness of the bent section 117, the material thickness of the longitudinal beam 102 connected to the bent section 117, and the material thickness of the crossbeam segment 103 at the end of the crossbeam 101 connected to the bent section 117 are all the same.

[0058] like Figure 4 and Figure 5 As shown, the present invention also proposes a vehicle body structure, including two sill beams 2 and the vehicle component 1 described in any of the above claims, wherein the two longitudinal beams 102 of the vehicle component 1 are respectively fixedly connected to the two sill beams 2.

[0059] The present invention also proposes a vehicle including the above-described body structure.
