Description

Body parts and vehicles Technical Field

[0001] This application relates to the field of vehicles, and more particularly to body parts and vehicles. Background Technology

[0002] In the vehicle manufacturing industry, as consumers' demands for vehicle safety levels continue to rise, it is necessary to strengthen the body structure of existing basic vehicles. This typically requires adding sheet metal parts inside the body to improve structural strength. Thermal expansion tubes are connecting devices used to absorb thermal expansion stress caused by temperature changes. They are widely used in construction, bridges, pipeline systems, aerospace, and machinery manufacturing, among other fields. Their main function is to alleviate structural stress concentration caused by differences in the thermal expansion coefficients of materials under different operating conditions through their elastic deformation or displacement capabilities, thereby improving the stability and service life of the system.

[0003] However, in many practical engineering applications, especially in the complex node connections of compact equipment, underground piping systems, ship cabins, aircraft internal structures, or high-rise buildings, installation space is extremely limited. Traditional thermal expansion tube structures typically employ large bellows, spring buffers, or multi-segment sliding compensation structures. While these designs can meet thermal compensation requirements in some aspects, they present significant problems under space constraints. Traditional thermal expansion tube compensation mechanisms often require long axial displacement spaces or large radial dimensions, making installation difficult in narrow passages or densely packed environments. Due to their complex structure, assembly of traditional thermal expansion tubes in confined spaces is difficult, potentially requiring the disassembly of surrounding components, increasing construction difficulty and time costs. In space-constrained areas, maintenance and replacement of traditional thermal expansion tubes are limited, impacting system maintainability and operational efficiency.

[0004] Therefore, it is necessary to provide an improved body component and vehicle to solve the above problems. Summary of the Invention

Detailed Implementation

[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0034] Referring to Figures 1 to 4, this application provides a vehicle body component, including a thermal expansion tube assembly 100 and a reinforcing plate assembly. The reinforcing plate assembly includes an upper side beam reinforcing plate 200 and a side outer panel reinforcing plate 300. The upper side beam reinforcing plate 200 and the side outer panel reinforcing plate 300 are connected together and form a closed annular structure. In an embodiment of this application, the thermal expansion tube assembly 100 is fixed to the upper side beam reinforcing plate 200 to improve the strength of the upper side beam reinforcing plate 200.

[0035] Referring to Figures 5 and 6, the thermal expansion tube assembly 100 includes a thermal expansion tube 10 and a reinforcing member 20. The thermal expansion tube 10 has a cavity 11 extending along its length. The reinforcing member 20 is assembled to the thermal expansion tube 10. By employing the combination of the thermal expansion tube 10 and the reinforcing member 20, this application can significantly reduce the volume of the thermal expansion tube assembly 100, and optimize the structural design through local reinforcement, reducing space occupation and ensuring good thermal expansion compensation effect.

[0036] The reinforcing plate assembly has a reinforcing area 301 and a non-reinforcing area 302. In the embodiments of this application, the upper beam reinforcing plate 200 is provided with a reinforcing area 301 and a non-reinforcing area 302, and the thermal expansion tube 10 is assembled to the reinforcing area 301. The thermal expansion tube 10 is integrally formed. The reinforcing member 20 is first welded to the thermal expansion tube 10, and then the thermal expansion tube 10 is welded to the reinforcing area 301. The sequential welding of the reinforcing member 20 and the thermal expansion tube 10 simplifies the process, improves the assembly accuracy, reduces assembly errors, and ensures a good fit.

[0037] Specifically, the reinforcing member 20 is welded to the thermal expansion tube 10 by CO2 shielded welding. The thermal expansion tube 10 is welded to the reinforcing zone 301 by CO2 shielded welding. The reinforcing member 20, the thermal expansion tube 10, and the reinforcing zone 301 are assembled using CO2 shielded welding to improve the stability of the welding and the connection strength.

[0038] According to other embodiments of this application, the reinforcing member 20 can be assembled to the thermal expansion tube 10 by bolts or riveting instead of welding. The thermal expansion tube 10 can be a modular design, which can be assembled into a complete thermal expansion tube 10 by plugging in parts.

[0039] According to the embodiments of this application, the thermal expansion tube 10 is made of hot-formed steel. The metal tube is heated to a set temperature, expanded using high-pressure gas, and then rapidly cooled to form the thermal expansion tube 10. The thermal expansion tube 10 is a variable cross-section tube, meaning that the cross-sectional area is different at different sections of the thermal expansion tube 10. The variable cross-section thermal expansion tube 10 better adapts to the shape of the reinforcing region 301, thereby improving the strength of the reinforcing region 301.

[0040] Referring to Figures 7 to 9, the reinforcing member 20 and the thermal expansion tube 10 together form a circumferentially closed reinforcing cavity 21, which improves the resistance to deformation, ensures the stability of thermal compensation, and reduces stress concentration. According to other embodiments of this application, the reinforcing cavity 21 may not be completely closed; instead, one or more opening structures may be provided on the reinforcing member 20 to accommodate the deformation capacity of the thermal expansion tube 10. Alternatively, multiple reinforcing members 20 may be used to form discontinuous reinforcing cavities 21 in segments.

[0041] According to other embodiments of this application, the reinforcing member 20 may also be designed as a sheet metal part that fits against the surface of the thermal expansion tube 10. There is no reinforcing cavity 21 between the reinforcing member 20 and the thermal expansion tube 10. The strength of the thermal expansion tube assembly 100 is improved only by the strength of the reinforcing member 20 in this application.

[0042] The thermal expansion tube 10 is made of the same material as the reinforcing member 20, both being hot-formed steel. By selecting the reinforcing member 20, which is made of the same material as the thermal expansion tube 10, the thermal expansion performance of the entire thermal expansion tube assembly 100 can be made consistent, avoiding inconsistent thermal expansion due to material mismatch. Specifically, in the embodiments of this application, the thermal expansion tube 10 is made of HC950 or HS1300 hot-formed steel.

[0043] According to the embodiments of this application, the material of the reinforcing plate assembly is high-strength steel. The material of the reinforcing plate assembly can also be replaced with other high-strength alloys or composite materials, such as aluminum alloys, carbon fiber, etc.

[0044] In the embodiments of this application, the reinforcing member 20 is an integrally formed structure. The reinforcing member 20 includes a first reinforcing plate 22 and a second reinforcing plate 23 bent from the first reinforcing plate 22. Both the first reinforcing plate 22 and the second reinforcing plate 23 are welded to the thermal expansion tube 10. By directly welding the integrally formed reinforcing member 20 to the thermal expansion tube 10, the number of parts can be reduced, the production process can be simplified, the manufacturing cost can be reduced, and the overall stability of the structure can be improved.

[0045] According to other embodiments of this application, the reinforcing member 20 can also be a separate component, such as the first reinforcing plate 22 and the second reinforcing plate 23 being manufactured separately and then assembled together. Furthermore, in the embodiments of this application, the first reinforcing plate 22 and the second reinforcing plate 23 are flat and arranged in a "V" shape. An included angle 24 is formed between the first reinforcing plate 22 and the second reinforcing plate 23, and the angle of the included angle 24 can be set according to requirements; this application does not impose any limitations on this. The first reinforcing plate 22 and the second reinforcing plate 23 can also be bent by an arc, such as the first reinforcing plate 22 and the second reinforcing plate 23 being "U"-shaped or "C"-shaped, to adapt to different shapes of the thermal expansion tube 10.

[0046] In the embodiments of this application, a single reinforcing member 20 is provided on the thermal expansion tube 10 in the area requiring local reinforcement. Alternatively, multiple reinforcing members 20 may be provided, assembled to multiple local areas of the thermal expansion tube 10, with multiple reinforcing members 20 disposed in multiple local areas of the thermal expansion tube 10. According to other embodiments of this application, multiple reinforcing members 20 may be spaced apart along the length of the thermal expansion tube 10 or spaced apart circumferentially. Multiple reinforcing members 20 may also be spaced apart both along the length of the thermal expansion tube 10 and circumferentially.

[0047] According to other embodiments of this application, multiple reinforcing members 20 may also be discretely disposed on the thermal expansion tube 10 to improve the flexibility of their reinforcing positions, optimize the reinforcing effect of the thermal expansion tube 10, and improve the overall durability of the component.

[0048] Referring to Figures 10 to 13, the reinforcing member 20 further includes a first welding portion 221 disposed at the end of the first reinforcing plate 22 and a second welding portion 231 disposed at the end of the second reinforcing plate 23. The reinforcing member 20 has an assembly gap when welded to the thermal expansion tube 10. Specifically, this assembly gap is reserved when the first reinforcing plate 22 is welded to the thermal expansion tube 10, and the same assembly gap is reserved when the second reinforcing plate 23 is welded to the thermal expansion tube 10. The distance of the assembly gap is greater than or equal to 3 mm.

[0049] The first weld portion 221 abuts against the first reinforcing plate 22 and the thermal expansion tube 10 and adheres to the outer surface of the thermal expansion tube 10. The second weld portion 231 abuts against the second reinforcing plate 23 and the thermal expansion tube 10 and adheres to the outer surface of the thermal expansion tube 10. The reinforcing member 20 is welded and fixed to the thermal expansion tube 10 through the first weld portion 221 and the second weld portion 231. In the embodiments of this application, the number of the first weld portion 221 and the second weld portion 231 is four. This application is not limited in this respect, and the number of the first weld portion 221 and the second weld portion 231 may be one or more.

[0050] According to an embodiment of this application, the first welding portion 221 and the second welding portion 231 are cylindrical. Four first welding portions 221 are spaced apart at the edge of the first reinforcing plate 22. Four second welding portions 231 are spaced apart at the edge of the second reinforcing plate 23. The thickness of the first welding portions 221 and the second welding portions 231 is greater than or equal to 3 mm to control the height of the carbon dioxide shielded welding.

[0051] The reinforcing member 20 is positioned using a fixture when welding to the thermal expansion tube 10. The thermal expansion tube 10 is also positioned using a fixture when welding to the reinforcing area 301. By setting an assembly gap for carbon dioxide shielded welding and positioning it using a fixture, the welding accuracy between the thermal expansion tube 10 and the reinforcing member 20, and between the thermal expansion tube 10 and the reinforcing area 301, is effectively ensured, avoiding assembly errors.

[0052] A liquid inlet hole 25 is provided at the connection between the first reinforcing plate 22 and the second reinforcing plate 23. In the embodiment of this application, there are two liquid inlet holes 25, and the reinforcing cavity 21 is a partially circumferentially closed cavity at the position of the liquid inlet hole 25. The second reinforcing plate 23 is also provided with a clearance hole 232 to avoid other body parts.

[0053] The reinforcing region 301 has a cavity 31, and the thermal expansion tube assembly 100 is located within the cavity 31. The cavity 31 includes a small cross-sectional area and a large cross-sectional area. The thermal expansion tube 10 is disposed in both the small cross-sectional area and the large cross-sectional area. The reinforcing member 20 is disposed in the large cross-sectional area. According to the embodiments of this application, when the thermal expansion tube 10 and the reinforcing member 20 together form a reinforcing cavity 21, there are at least two cavities in the small cross-sectional area, such as the cavity between the thermal expansion tube 10 and the reinforcing region 301 and the empty cavity 11; and at least three cavities in the large cross-sectional area, such as the cavity between the reinforcing member 20 and the reinforcing region 301, the reinforcing cavity 21, and the empty cavity 11.

[0054] This application, by forming a cavity 31 in the reinforcing zone 301 and setting small and large cross-sectional areas of different sizes, allows the thermal expansion tube assembly 100 to be effectively arranged in two different spatial regions. This ensures the rational configuration of the thermal expansion tube assembly 100 within a confined space and improves the structural compactness of the vehicle body components. The thermal expansion tube 10 runs through most of the cavity 31, but the reinforcing member 20 is only installed in the large cross-sectional area because the large cross-sectional area has sufficient space to accommodate the reinforcing member 20 and the thermal expansion tube 10, while the small cross-sectional area only houses the thermal expansion tube 10 to save space. This design achieves optimized space allocation, ensuring effective reinforcement even in narrow areas while avoiding interference.

[0055] According to other embodiments of this application, the cavity 31 may be divided into multiple cross-sectional areas rather than just two, arranged according to spatial gradients to accommodate reinforcing members 20 of different sizes. Where space permits, the reinforcing members 20 may also be located in small cross-sectional areas, or flexible reinforcing materials may be used to adapt to narrow areas.

[0056] The specific assembly steps of the vehicle body components of this application are as follows: First, the thermal expansion tube 10 and the reinforcing member 20 are positioned using a fixture, ensuring an assembly gap of at least 3 mm between the first reinforcing plate 22 and the second reinforcing plate 23 and the thermal expansion tube 10; and the first welding part 221 and the second welding part 231 both abut against the outer surface of the thermal expansion tube 10. Then, the reinforcing member 20 is welded to a local area of ​​the thermal expansion tube 10 using CO2 shielded welding to form a thermal expansion tube assembly. Next, the thermal expansion tube assembly 100 and the upper side beam reinforcing plate 200 are positioned using a fixture, ensuring an assembly gap of at least 3 mm between the thermal expansion tube 10 and the upper side beam reinforcing plate 200. Subsequently, the thermal expansion tube 10 is welded to the upper side beam reinforcing plate 200 using CO2 shielded welding. Finally, the height of the CO2 shielded weld is measured using a gauge; if the joint at the weld exceeds the assembly tolerance, the deviation can be eliminated by grinding.

[0057] This application also provides a vehicle including the aforementioned body components.

[0058] The reinforcing member 20 of this application is installed in a local area of ​​the thermal expansion tube 10. While ensuring thermal compensation performance and structural strength, it significantly reduces the size of the thermal expansion tube assembly 100, effectively solving the installation and arrangement problem of the reinforcing member 20 in a narrow cavity space. At the same time, the thermal expansion tube 10 is combined with the reinforcing area 301 of the reinforcing plate assembly to achieve precise local reinforcement, making installation and maintenance convenient.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
