Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a vehicle connection structure and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry in recent years, the connecting structure of a vehicle includes an outer panel assembly, reinforcing plates, and an inner panel assembly. During assembly, the outer panel assembly and reinforcing plates are usually assembled into an outer panel assembly, and then the inner panel assembly is installed onto the outer panel assembly to achieve the assembly of the three. However, automobiles often incorporate more decorative parts with various shapes and styles, such as front and rear bumpers, headlights, and surrounding side panels. Assembling the outer panel assembly and reinforcing plates first can lead to gaps and surface differences between the outer panel assembly and the decorative parts during assembly, affecting the final appearance of the assembled vehicle. Utility Model Content

[0003] In view of this, this application provides a vehicle connection structure to solve the problem of gaps and surface differences between the outer panel assembly and the trim pieces, resulting in poor molding effects during vehicle assembly. This application also provides a vehicle including the above-described vehicle connection structure.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A vehicle connection structure includes an outer panel assembly, an inner panel assembly, and a reinforcing plate disposed between the inner panel assembly and the outer panel assembly. The inner panel assembly and the reinforcing plate are connected by a first weld to form an inner panel assembly. The outer panel assembly is connected to the side of the inner panel assembly where the reinforcing plate is located.

[0006] Optionally, the outer panel assembly is connected to the inner panel assembly via a second solder mark, and the second solder mark includes a plurality of solder points spaced apart along the connection direction.

[0007] Optionally, the outer panel assembly is connected to the inner panel assembly by bolts.

[0008] Optionally, the outer panel assembly is connected to the inner panel assembly by structural adhesive, and the structural adhesive is continuously provided in the connection direction.

[0009] Optionally, any two of the second weld mark, bolt, and structural adhesive may not overlap.

[0010] Optionally, multiple bolts are spaced apart in the connection direction, and the multiple bolts are located in the middle of the inner plate assembly.

[0011] Optionally, the first solder mark is formed by double-sided welding; and / or, the second solder mark is formed by single-sided welding.

[0012] Optionally, a limiting structure is provided between the reinforcing plate and the outer plate assembly, and the structural adhesive surrounds at least a portion of the limiting structure.

[0013] A vehicle comprising the connection structure of any of the preceding claims.

[0014] Optionally, the vehicle's connection structure is at least one of the vehicle's A-pillar, B-pillar, or C-pillar.

[0015] The vehicle connection structure provided in this application, during the assembly process, first assembles the inner panel assembly and the reinforcing plate into an inner panel assembly, then connects the outer panel assembly and the inner panel assembly together, and finally assembles the outer panel assembly. This allows for fine-tuning during the assembly of the outer panel assembly to adjust its installation position, thereby reducing the gap and surface difference between the decorative parts and the outer panel assembly, and thus improving the molding effect after vehicle assembly.

[0024] This application provides a connection structure for a vehicle. This application also provides a vehicle including the above-described connection structure.

[0025] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] like Figures 1-4 As shown, this application embodiment provides a vehicle connection structure 1, including an outer panel assembly 11, an inner panel assembly 12, and a reinforcing plate 13 disposed between the inner panel assembly 12 and the outer panel assembly 11. The inner panel assembly 12 and the reinforcing plate 13 are connected by a first weld (not shown in the figure) to form an inner panel assembly 14, and the outer panel assembly 11 is connected to the side of the inner panel assembly 14 where the reinforcing plate 13 is located. That is, in the process of assembling the vehicle connection structure 1, the inner panel assembly 12 and the reinforcing plate 13 are first connected together by the first weld to form the inner panel assembly 14, and then the outer panel assembly 11 and the inner panel assembly 14 are connected together, thus realizing the assembly of the outer panel assembly 11, the inner panel assembly 12, and the reinforcing plate 13. In the prior art, the outer panel assembly 11 and the reinforcing plate 13 are first assembled into an outer panel assembly, and then the outer panel assembly and the inner panel assembly 12 are assembled. Compared with the assembly method in the prior art, the assembly method of the vehicle connection structure 1 in this application changes the assembly method and assembly order so that the outer panel assembly 11 is assembled last. This allows for fine-tuning of the installation position of the outer panel assembly 11 to meet the appearance matching requirements of the vehicle's decorative parts, adjust the gap and surface difference between the outer panel assembly 11 and the decorative parts, improve the assembly accuracy of the vehicle's connection components, and enhance the stability of its structure.

[0027] It should be noted that the location of the vehicle connection structure 1 in the vehicle is not limited here. The vehicle connection structure 1 can be any component in the vehicle that needs to be connected.

[0028] It should also be noted that the first weld mark is formed by double-sided welding. This setting can improve the connection strength between the inner assembly and the reinforcing plate 13, improve the stability of the connection between the two, and thus improve the overall structural strength of the connection structure 1.

[0029] In the above-described vehicle connection structure 1, during the assembly process, the inner panel assembly 12 and the reinforcing plate 13 are first assembled into the inner panel assembly 14, and then the outer panel assembly 11 and the inner panel assembly 14 are connected together. By finally assembling the outer panel assembly 11, the installation position of the outer panel assembly 11 can be adjusted by fine-tuning during assembly, so as to reduce the gap and surface difference between the decorative parts and the outer panel assembly 11, thereby improving the molding effect after vehicle assembly.

[0030] In some embodiments, please refer to Figures 1 to 4 The outer panel assembly 11 is connected to the inner panel assembly 14 via a second weld mark 15. This second weld mark 15 improves the ease of connection and structural strength between the two. Furthermore, the second weld mark 15 includes multiple weld points spaced apart along the connection direction, ensuring a more balanced connection force between the outer panel assembly 11 and the inner panel assembly 14, thus enhancing connection stability. Moreover, the evenly spaced weld points of the second weld mark 15 ensure balanced stress distribution at the connection point when external forces are applied, further improving connection stability.

[0031] It should be noted that the connection direction between the outer panel assembly 11 and the inner panel assembly 14 is... Figure 3 The direction indicated by the double-headed arrow Z.

[0032] It should also be noted that since the inner panel assembly 12 is provided on the side of the reinforcing plate 13 away from the outer panel assembly 11, the second weld mark 15 is formed by single-sided welding to improve the stability of the connection between the reinforcing plate 13 of the outer panel assembly 11 and the inner panel assembly 14.

[0033] Further details based on the above embodiments can be found in the following examples. Figures 1 to 4 The outer panel assembly 11 is connected to the inner panel assembly 14 by bolts 16. That is to say, based on the connection between the outer panel assembly 11 and the inner panel assembly 14 via the second weld 15, bolts 16 are also provided between the outer panel assembly 11 and the inner panel assembly 14. In other words, the connection between the outer panel assembly 11 and the inner panel assembly 14 is achieved through the cooperation of the second weld 15 and bolts 16. This can further improve the stability of the connection between the outer panel assembly 11 and the inner panel assembly 14, thereby improving the overall stability of the vehicle's connection structure 1.

[0034] Further details based on the above embodiments can be found in the following examples. Figures 1 to 4 The outer panel assembly 11 is connected to the inner panel assembly 14 via structural adhesive 17. In other words, in addition to the connection between the outer panel assembly 11 and the inner panel assembly 14 via the second weld 15, structural adhesive 17 is also provided between the outer panel assembly 11 and the inner panel assembly 14. This means that the connection between the outer panel assembly 11 and the inner panel assembly 14 is achieved through the combined use of the second weld 15 and structural adhesive 17, thereby improving the stability of the connection between the outer panel assembly 11 and the inner panel assembly 14. Furthermore, the structural adhesive 17 is continuously provided in the connection direction, ensuring the integrity of the structural adhesive 17 as a whole, improving the connection stability between the outer panel assembly 11 and the inner panel assembly 14. The structural adhesive 17 also has a certain thickness, which can act as a seal, preventing moisture and other substances from entering the interior of the vehicle's connection structure 1, thus improving the waterproof performance of the connection structure 1.

[0035] For further details, please refer to Figure 3 The outer panel assembly 11 and the inner panel assembly 14 are connected by three methods: second weld mark 15, bolt 16 and structural adhesive 17. This can further improve the stability of the connection between the two and further improve the structural stability of the vehicle's connection structure 1.

[0036] Of course, the outer panel assembly 11 and the inner panel assembly 14 can also be connected by bolts 16 and structural adhesive 17. This arrangement can also improve the stability of the connection between the outer panel assembly 11 and the inner panel assembly 14.

[0037] In some embodiments, please refer to Figures 1 to 4 The second weld mark 15, bolt 16, and structural adhesive 17 are all non-overlapping. In other words, no two of the three are in contact. This arrangement ensures the stability of the connection between the second weld mark 15, bolt 16, and structural adhesive 17 to the outer panel assembly 11 and the inner panel assembly 14, and avoids one connection method affecting the other connection methods.

[0038] Of course, two of the three components, namely the second weld mark 15, the bolt 16 and the structural adhesive 17, may overlap. For example, the structural adhesive 17 and the bolt 16 may partially overlap. The adhesive force of the structural adhesive 17 will fill the gaps in the threads of the bolt 16, thereby improving the adhesive performance of the bolt 16 and thus improving the stability of the connection between the outer panel assembly 11 and the inner panel assembly 14.

[0039] In some embodiments, please refer to Figures 1 to 4 Multiple bolts 16 are spaced apart in the connection direction, and the multiple bolts 16 are located in the middle of the inner panel assembly 14. After the outer panel assembly 11 and the inner panel assembly 14 are connected together in the manner described in the above embodiment, the middle part of the vehicle's connection structure 1 is a relatively weak area and is prone to deformation when subjected to external forces. In this embodiment, the arrangement can enhance the structural strength of the middle connection area between the outer panel assembly 11 and the inner panel assembly 14, thereby preventing the vehicle's connection structure 1 from bending or breaking when subjected to external forces, and thus improving the stability of the vehicle's connection structure 1.

[0040] In some embodiments, please refer to Figures 1 to 4A limiting structure 18 is provided between the reinforcing plate 13 and the outer plate assembly 11. For example, the limiting structure 18 may include a protrusion on one of the reinforcing plate 13 and the outer plate assembly 11, and a groove on the other that matches the protrusion. The limiting structure 18 may also include limiting holes aligned on the reinforcing plate 13 and the outer plate assembly 11, and pins that can pass through the two limiting holes. Furthermore, structural adhesive 17 surrounds at least a portion of the limiting structure 18. Specifically, since structural adhesive 17 is a high-strength, high-durability adhesive, mainly used for structural bonding that bears large loads or requires long-term stability, surrounding at least a portion of the limiting structure 18 with structural adhesive 17 prevents moisture from entering the limiting structure 18 from the outside, thus achieving a waterproof effect. Moreover, structural adhesive 17 typically has a certain thickness, and it also acts as a buffer and shock absorber, preventing the limiting structure 18 from shaking and producing abnormal noise.

[0041] It should be noted that the structural adhesive 17 surrounding the limiting structure 18 includes at least two situations: the structural adhesive 17 completely surrounds the limiting structure 18, that is, the structural adhesive 17 surrounds the circumferential outer side of the limiting structure 18, such as... Figure 3 Region E of the structural adhesive 17; the structural adhesive 17 surrounds a local area of ​​the limiting structure 18, that is, the structural adhesive 17 surrounds the outer side of a local circumference of the limiting structure 18, as shown in the image. Figure 3 The F region of structural adhesive 17.

[0042] A vehicle includes a vehicle connection structure 1 as described above. Since the vehicle includes the aforementioned vehicle connection structure 1, the beneficial effects of the vehicle brought about by the vehicle connection structure 1 are described above and will not be repeated here.

[0043] In some embodiments, the vehicle's connection structure 1 is at least one of the vehicle's A-pillar, B-pillar, or C-pillar. The A-pillar is located on both sides of the windshield, connecting the roof to the front door frame, and is used to withstand the impact force during a frontal collision; the B-pillar is located between the front and rear doors, connecting the roof to the side of the vehicle body, and is used to resist the impact force during a side collision; the C-pillar is located on both sides of the rear windshield, connecting the roof to the rear door frame or trunk, and is used to enhance the overall rigidity of the vehicle body. Of course, the vehicle's connection structure 1 in the above embodiments can also be other components of the vehicle or located in other positions within the vehicle.
