Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a wall-mounted corner assembly. Background Art

[0002] In modern automotive design, door sealing performance and structural stability are crucial factors influencing overall vehicle quality and user experience. The design of the corner assembly between the door and the A-pillar also directly impacts the door's sealing performance. Existing designs primarily rely on securing an extruded strip skeleton to the sheet metal, achieving sealing and support through an interference fit. However, this design has exposed several technical issues in practical applications, particularly regarding deformation and fit at the corner.

[0003] Related prior art, such as the Chinese patent application "A Sealing Structure for a Frameless Car Door A-pillar", application number: CN202122006261.2, discloses an A-pillar sheet metal and a car door outer triangle panel, wherein a top glass guide channel body is provided on the A-pillar sheet metal, an A-pillar guide channel body corner is provided on the car door outer triangle panel, and a bubble is provided on the top glass guide channel body. When the car door is closed, the bubble and the A-pillar guide channel body corner are squeezed and sealed. A sealing foam is also provided between the bright strip frame and the A-pillar sheet metal, and the sealing foam is located at the connection part of the fastener. A glass guide groove is provided on the top glass guide channel body, and the bubble is located on the inner wall of the glass guide groove. A lip opposite to the bubble is also provided on the inner wall of the glass guide groove, and the lip is squeezed and sealed with the A-pillar guide channel body corner.

[0004] First, during installation, traditional corner assemblies rely on an interference fit between the extruded strip and the sheet metal. While this approach can ensure a certain degree of sealing, it carries a high risk of deformation in actual use. Due to the forces and vibrations experienced during door opening and closing, the corner may undergo slight displacement or deformation, resulting in a gap between the corner and the sheet metal. This gap not only compromises the door's sealing performance but can also allow air and water to infiltrate, impacting the vehicle's NVH (noise, vibration, and harshness) performance and diminishing the driving experience.

[0005] Secondly, existing corner assemblies lack an effective reference positioning mechanism. Without a reliable positioning structure during the matching process between the corner and the sheet metal, the corner may be inaccurately positioned during installation, further exacerbating the decline in sealing performance.

[0006] To address these issues, a new angle joint assembly structure was proposed. This solves the deformation and gap issues that may occur during installation of the original angle joint assembly, improves the sealing between the door and the A-pillar, and provides more reliable technical support. Utility Model Content

[0007] The technical problem to be solved by this application is to provide a wall-mounted corner joint assembly, in which a fixed insert is added inside the corner joint, which is effectively hung on the sheet metal through the insert and can also serve as a reference positioning, effectively preventing the generation of gaps, thereby improving the sealing performance of the corner joint and the stability of the overall structure.

[0008] The technical solution adopted in this application is: a wall-mounted corner joint assembly, including sheet metal, an insert, and a corner joint connected to the sealing strip, the insert including a curved base plate, and a hook and end piece connected to both ends of the base plate, the base plate and end piece are both embedded in the corner joint, and a groove is provided on a side of the corner joint close to the sheet metal, the hook protrudes from the bottom surface of the groove of the corner joint, and the sheet metal part is inserted between the hook and the bottom surface of the groove.

[0009] Compared to existing technologies, the advantages of this application are: first, by adding an insert inside the corner, it can effectively rely on the insertion of the insert and the sheet metal for positioning, ensuring accurate installation of the corner and reducing the reduction in sealing performance caused by inaccurate positioning. Second, the new structure can effectively prevent gaps from forming between the corner and the sheet metal. When matching multiple vehicle models, it can indirectly compensate for gaps caused by corner deformation during the turnover process, thereby achieving a better sealing effect.

[0010] Furthermore, the insert and the corner joint can be injection molded together, eliminating the need for subsequent clip installation, streamlining the production process, improving efficiency, and reducing costs. In summary, the fixed insert design provides a better seal at the corner joint, reducing air and water infiltration, improving the vehicle's NVH (noise, vibration, and harshness) performance, and enhancing the user's driving experience.

[0011] In some embodiments of the present application, the corner includes a first end and a second end. The groove is located at the first end of the corner, and the end surface of the second end of the corner engages with the sealing strip. The end piece is embedded within the second end. This embedded end piece provides better structural support, reduces the risk of deformation due to external forces, and thus improves the stability of the overall structure. This integrated design can reduce subsequent assembly steps, improve production efficiency, and reduce production costs.

[0012] In some embodiments of the present application, the hook is a bent plate-like structure comprising a limiting segment and a guiding segment. One end of the limiting segment is connected to the base plate, and the other end is connected to the guiding segment. Compared to traditional planar structures, the bent plate-like structure provides greater strength and rigidity, enhancing the hook's load-bearing capacity and reducing deformation caused by external forces during use.

[0013] In some embodiments of the present application, the limiting section is arranged parallel to the bottom surface of the groove, an angle is formed between the guide section and the bottom surface of the groove, and the sheet metal portion is inserted between the limiting section and the bottom surface of the groove. The angle between the guide section and the bottom surface of the groove can guide the sheet metal portion to be inserted between the limiting section and the bottom surface of the groove more smoothly, simplifying the installation process and reducing errors during installation. By inserting the sheet metal portion between the limiting section and the bottom surface of the groove, the gap between the joint angle and the sheet metal can be effectively reduced, improving the overall sealing effect and preventing the infiltration of air and water.

[0014] In some embodiments of the present application, the base plate is a plate-like structure curved along the length of the corner. A retaining hole is defined on the base plate surface, and the insert is integrally injection-molded with the corner, with the corner portion embedded within the retaining hole. The curved plate-like structure provides improved strength and rigidity, enhancing the overall stability of the corner and reducing deformation due to external forces. The design of integrally injection-molding the insert and corner can reduce subsequent assembly steps, improve production efficiency, reduce production costs, and ensure component quality and consistency.

[0015] In some embodiments of the present application, the sealing strip is embedded with a frame having a U-shaped cross-section. The end pieces are U-shaped structural members, with one end of the end piece positioned opposite the frame. The U-shaped end pieces provide greater structural strength, forming a tighter seal when the corners connect to the sealing strip, reducing air and water infiltration, and thus improving overall sealing performance.

[0016] In some embodiments of the present application, the end piece is a non-straight bar structure, with the opening on the side of the end piece closer to the substrate having a larger diameter than the opening on the side farther from the substrate. This design provides improved structural strength while maintaining lightweight, reducing the risk of deformation due to external forces. A rational shape design can improve the durability of the end piece and extend its service life.

[0017] In some embodiments of the present application, the end piece is provided with a latch hole on its surface, into which the corner portion is embedded. The addition of the latch hole structure improves the reliability of the connection between the end piece and the corner portion, enhances the stability of the overall structure, and reduces displacement or deformation caused by external forces during use.

[0018] In some embodiments of the present application, one end of the substrate is connected to the hook, and the other end of the substrate is connected to the corner of the end piece, and the end piece is perpendicular to the other end of the substrate.

[0019] In some embodiments of the present application, the baseplate is provided with a reinforcement strip that connects the baseplate to the end piece. This reinforcement strip design significantly improves the overall strength and rigidity of the baseplate, reduces deformation caused by external forces during use, and ensures the stability of the assembly. The reinforcement strip effectively disperses forces applied to the baseplate and end piece, reducing localized stress concentrations and thereby improving the durability and reliability of the overall structure.

[0027] The present application will be described in detail below with reference to the accompanying drawings.

[0028] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0029] A wall-mounted corner assembly, embodiment 1 Figure 1 、 Figure 2As shown: It includes a sheet metal 1, an insert 2, and a corner joint 4 that connects to a sealing strip 3. The insert 2 includes a curved base plate 5, a hook 6 and an end piece 7 connected to the two ends of the base plate 5. The base plate 5 and the end piece 7 are both embedded in the corner joint 4. The insert 2 and the corner joint 4 can be injection molded together, eliminating the labor of subsequent buckle installation, simplifying the production process, improving production efficiency, and reducing production costs. The corner joint 4 has a groove 8 on the side near the sheet metal 1. The hook 6 extends through the bottom surface of the groove 8 of the corner joint 4, and the sheet metal 1 is partially inserted between the hook 6 and the bottom surface of the groove 8. By adding the insert 2 inside the corner joint 4, the insert 2 can be effectively positioned by relying on the hooking of the sheet metal 1, ensuring the accurate installation of the corner joint 4 and reducing the reduction in sealing performance caused by inaccurate positioning.

[0030] The design of the fixed insert 2 can provide a better sealing effect at the joint corner 4, reduce the infiltration of air and water, improve the NVH (noise, vibration and harshness) performance of the entire vehicle, and enhance the user's driving experience.

[0031] Example 2, as Figures 1 to 4 As shown, the corner 4 includes a first end and a second end. The groove 8 is located at the first end of the corner 4. The end surface of the second end of the corner 4 engages with the sealing strip 3. The end piece 7 is embedded within the second end. This embedded end piece 7 provides better structural support, reduces the risk of deformation due to external forces, and thus improves the stability of the overall structure. This integrated design can reduce subsequent assembly steps, improve production efficiency, and reduce production costs.

[0032] The hook 6 is a bent plate-like structure comprising a limiting segment 9 and a guide segment 10. One end of the limiting segment 9 is connected to the base plate 5, and the other end of the limiting segment 9 is connected to the guide segment 10. Compared to a traditional planar structure, the bent plate-like structure provides greater strength and rigidity, enhances the load-bearing capacity of the hook 6, and reduces deformation caused by external forces during use.

[0033] The limiting section 9 is positioned parallel to the bottom surface of the groove 8. The guide section 10 forms an angle with the bottom surface of the groove 8, and the sheet metal 1 is partially inserted between the limiting section 9 and the bottom surface of the groove 8. This angle between the guide section 10 and the bottom surface of the groove 8 guides the sheet metal 1 portion more smoothly between the limiting section 9 and the bottom surface of the groove 8, simplifying the installation process and reducing installation errors. By partially inserting the sheet metal 1 between the limiting section 9 and the bottom surface of the groove 8, the gap between the joint 4 and the sheet metal 1 is effectively reduced, improving the overall sealing effect and preventing the infiltration of air and water.

[0034] The base plate 5 is a curved plate-like structure extending along the length of the corner 4. A retaining hole 11 is defined on its surface. The insert 2 is integrally injection-molded with the corner 4, with the corner 4 partially embedded within the retaining hole 11. This curved plate-like structure provides enhanced strength and rigidity, enhancing the overall stability of the corner 4 and reducing deformation due to external forces. The integral injection molding of the insert 2 and corner 4 reduces subsequent assembly steps, improving production efficiency and reducing costs, while ensuring component quality and consistency.

[0035] The sealing strip 3 is embedded with a frame 12 having a U-shaped cross-section. The end piece 7 is a U-shaped structural member, with one end of the end piece 7 positioned opposite the frame 12. The U-shaped end piece 7 provides greater structural strength, forming a tighter seal when the corner 4 is connected to the sealing strip 3, reducing the infiltration of air and water, thereby improving the overall sealing performance.

[0036] The end piece 7 is a non-straight bar-shaped structure. The opening on the side of the end piece 7 closest to the base plate 5 is larger than the opening on the side away from the base plate 5. This design provides greater structural strength while maintaining lightweight, reducing the risk of deformation due to external forces. Through a rational shape design, the durability of the end piece 7 can be improved, extending its service life.

[0037] The end piece 7 is provided with a latch hole 11 on its surface, into which the corner 4 is partially embedded. The addition of the latch hole 11 improves the reliability of the connection between the end piece 7 and the corner 4, enhances the stability of the overall structure, and reduces displacement or deformation caused by external forces during use.

[0038] One end of the base plate 5 is connected to the hook 6 , and the other end of the base plate 5 is connected to the corner of the end piece 7 , and the end piece 7 is perpendicular to the other end of the base plate 5 .

[0039] The base plate 5 is provided with a reinforcement strip 13, which connects the base plate 5 to the end piece 7. The design of the reinforcement strip 13 significantly improves the overall strength and rigidity of the base plate 5, reduces deformation caused by external forces during use, and ensures the stability of the assembly. The reinforcement strip 13 effectively distributes the forces applied to the base plate 5 and end piece 7, reducing localized stress concentration, thereby improving the durability and reliability of the overall structure.
