Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, and in particular to an anti-deformation structure for the upper pillar guard plate of an automobile. Background Technology

[0002] The anti-deformation structure of the automotive upper pillar guard plate plays a crucial role in the assembly and long-term use of the car body. It is used to enhance the structural stability of the upper pillar guard plate and related components, resist external pressure and vibration impact, and fix and protect the upper pillar guard plate, interior and air ducts from deformation. This ensures the integrity of the car body appearance, the ventilation function of the car body and the assembly accuracy of the interior components, and avoids problems such as abnormal noise and functional failure caused by deformation. The anti-deformation structure of the automotive upper pillar guard plate is widely used in the assembly of A-pillar guard plates of various passenger cars.

[0003] When strengthening the structural stability of the upper pillar guard plate and related components to resist external extrusion and vibration impact, and to fix and protect the upper pillar guard plate, interior trim, and air duct from deformation, an anti-deformation structure for automotive upper pillar guard plates is required. Existing anti-deformation structures for automotive upper pillar guard plates are mostly separate designs of a single rigid reinforcement component and the guard plate body. They require additional welding and multiple assembly processes to achieve connection, which can easily lead to problems such as component misalignment and stress concentration at welding points during assembly. In addition, more labor and testing costs are required to correct errors, which will significantly increase production costs. At the same time, the connection strength of the separate structure is easily affected by the assembly precision, and the buckles are prone to loosening, resulting in reduced product quality and shortened service life. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an anti-deformation structure for the upper pillar guard plate of automobiles, aiming to improve the problems of complex assembly and short service life of the split structure in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: A deformation-resistant structure for an automotive A-pillar guard plate, comprising a mounting column, an outer shell fixedly connected to the inner wall of the mounting column, a wedge-shaped groove fixedly connected to the inner wall of the outer shell, multiple through holes formed in the inner wall of the wedge-shaped groove, compression springs fixedly connected to the inner walls of the through holes, a wedge-shaped block slidingly attached to the inner wall of the wedge-shaped groove, a positioning protrusion fixedly connected to the front side of the wedge-shaped block, a butterfly spring slidably connected to the front side of the positioning protrusion, a mounting boss slidably connected to the outer wall of the butterfly spring, an air duct fixedly connected to the front end of the mounting boss, an interior trim panel connected to the inner wall of the air duct, and a support mechanism fixedly connected to the outer wall of the mounting column. The support mechanism is used to support the interior trim panel to prevent deformation due to compression and positional displacement.

[0006] As a further description of the above technical solution: The support mechanism includes a mounting plate, the bottom of which is fixedly connected to the outer wall of a mounting column. A plurality of limiting blocks are fixedly connected to the front side of the mounting plate. A rotating shaft is rotatably connected to the inner wall of each of the limiting blocks. A cross link is rotatably connected to the outer wall of the rotating shaft. A first rotating disk is fixedly connected to the inner wall of the cross link. A connecting column is rotatably connected to the inner wall of the first rotating disk. A second rotating disk is rotatably connected to the top of the connecting column. A spiral spring is rotatably connected to the outer wall of the connecting column.

[0007] As a further description of the above technical solution: The inner wall of the interior panel is fixedly connected with multiple baffles, and the adjacent baffles are fixedly connected with pins.

[0008] As a further description of the above technical solution: The inner wall of the mounting column is provided with a positioning groove and an arc-shaped groove.

[0009] As a further description of the above technical solution: A positioning plate is fixedly connected to the inner wall of the air duct, and the rear side of the positioning plate is slidably connected to the inner wall of the interior panel.

[0010] As a further description of the above technical solution: The positioning plate has multiple air outlets on its inner wall and multiple mounting holes near its edge.

[0011] As a further description of the above technical solution: The inner wall of the mounting hole is slidably connected to a bolt, and the inner wall of the bolt is threadedly connected to the inner wall of the interior panel.

[0012] As a further description of the above technical solution: The inner wall of the interior panel is fixedly connected with multiple support ribs, and the inner wall of the interior panel is fixedly connected with reinforcing rods.

[0013] This utility model has the following beneficial effects: 1. In this utility model, during installation, the outer shell of the mounting column is fixed with a wedge-shaped groove. The compression spring in the through hole of the inner wall of the wedge-shaped groove applies a pushing force to the sliding wedge block in the groove. The positioning protrusion on the front side of the wedge block pushes the butterfly spring, causing the butterfly spring to deform within the mounting boss, forming an elastic lock, tightly connecting the wedge block and the mounting boss. The mounting boss fixes the air duct, thereby stabilizing the connected interior panel. When subjected to external force, the compression spring and the butterfly spring buffer the force, and the wedge structure prevents loosening, ensuring the stability of the position of each component, avoiding deformation and displacement of the guard plate and interior panel, which can improve product quality and increase service life.

[0014] 2. In this utility model, during installation, the bottom of the mounting plate is fixed to the outer wall of the mounting column, providing a stable base for the mechanism. When the interior trim is squeezed by external force, the force is transmitted to the cross link. The cross link rotates flexibly through the rotating shaft connected to the inner wall of the limiting block to adjust the support angle. At the same time, the first rotating disk on the inner wall of the cross link rotates around the connecting column, and the second rotating disk at the top of the connecting column rotates synchronously to ensure smooth multi-angle adjustment of the link. The spiral spring on the outer wall of the connecting column deforms with the rotation of the link to absorb the impact of external force. After deformation, it releases the elastic force to assist the link in resetting, preventing the interior trim from deforming and shifting due to continuous external force.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3This utility model provides an embodiment of an anti-deformation structure for an upper pillar guard plate of a car, including a mounting post 1, an outer shell 3 fixedly connected to the inner wall of the mounting post 1, a wedge groove 4 fixedly connected to the inner wall of the outer shell 3, a plurality of through holes 5 opened on the inner wall of the wedge groove 4, a compression spring 6 fixedly connected to the inner wall of the through holes 5, a wedge block 7 slidingly connected to the inner wall of the wedge groove 4, a positioning protrusion 8 fixedly connected to the front side of the wedge block 7, a butterfly spring 9 slidably connected to the front side of the positioning protrusion 8, a mounting boss 10 slidably connected to the outer wall of the butterfly spring 9, an air duct 11 fixedly connected to the front end of the mounting boss 10, an interior panel 12 connected to the inner wall of the air duct 11, and a support mechanism 2 fixedly connected to the outer wall of the mounting post 1. The support mechanism 2 is used to support the interior panel to prevent it from being squeezed and deformed, which would cause it to shift position. Specifically, the mounting post 1 serves as a basic support component, and its inner wall is fixed with a shell 3, which provides a mounting carrier for the wedge-shaped groove 4. Multiple through holes 5 on the inner wall of the wedge-shaped groove 4 fix compression springs 6, which can apply elastic thrust to the sliding wedge block 7. In conjunction with the positioning protrusion 8 on the front side of the wedge block 7, it can form an elastic compression lock with the sliding disc spring 9 inside the mounting boss 10, enhancing the connection stability between the wedge block 7 and the mounting boss 10, thereby fixing the air duct 11 at the front end of the mounting boss 10 and preventing the displacement of the air duct 11 from affecting the positional stability of the interior panel 12 connected to the air duct 11. At the same time, the support mechanism 2 on the outer wall of the mounting post 1 can directly support the interior, effectively resisting external pressure and preventing the interior from shifting due to compression deformation. The overall structure achieves the dual functions of anti-deformation and position fixation through the elastic connection and rigid support of multiple components.

[0019] Please see the appendix Figure 2 and attached Figure 4 The support mechanism 2 includes a mounting plate 201. The bottom of the mounting plate 201 is fixedly connected to the outer wall of the mounting column 1. Multiple limiting blocks 202 are fixedly connected to the front side of the mounting plate 201. The inner walls of the multiple limiting blocks 202 are rotatably connected to a rotating shaft 203. The outer wall of the rotating shaft 203 is rotatably connected to a cross link 204. The inner wall of the cross link 204 is fixedly connected to a first rotating disk 205. The inner wall of the first rotating disk 205 is rotatably connected to a connecting column 206. The top of the connecting column 206 is rotatably connected to a second rotating disk 207. The outer wall of the connecting column 206 is rotatably connected to a spiral spring 208. Specifically, the core function of the support mechanism 2 is to stably support the interior trim and prevent it from being squeezed, deformed, or shifted. The bottom of the mounting plate 201 is fixed to the outer wall of the mounting column 1, providing a fixed foundation for the entire mechanism. Multiple limiting blocks 202 on its front side allow the cross link 204 to rotate flexibly via the rotating shaft 203 on the inner wall, adapting to the position adjustment of the interior trim under different stress states. The first rotating disk 205, connecting column 206, and second rotating disk 207 on the inner wall of the cross link 204 cooperate to achieve multi-angle rotation between the links, enhancing the support flexibility. The spiral spring 208 on the outer wall of the connecting column 206 can deform and store force when the cross link 204 rotates, buffering external force impacts and avoiding damage to the interior trim caused by rigid support, thus ensuring the overall stability of the interior trim position.

[0020] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 Multiple baffles 13 are fixedly connected to the inner wall of the interior panel 12, and pins 14 are fixedly connected between adjacent baffles 13. A positioning plate 17 is fixedly connected to the inner wall of the air duct 11. The rear side of the positioning plate 17 is slidably connected to the inner wall of the interior panel 12. A positioning groove 15 is provided on the inner wall of the mounting column 1, and an arc groove 16 is provided on the inner wall of the mounting column 1. Specifically, multiple baffles 13 on the inner wall of the interior panel 12 cooperate with adjacent pins 14 to form a limiting structure, preventing the internal components of the interior panel 12 from loosening or shifting. The positioning plate 17 on the inner wall of the air duct 11 is slidably connected to the inner wall of the interior panel 12, which can help the interior panel 12 to accurately align with the air duct 11 and avoid misalignment during installation. The positioning groove 15 and arc groove 16 on the inner wall of the mounting column 1 can provide an installation positioning reference for related components, further ensuring the positional stability of the interior panel 12 and connecting components and reducing the risk of deformation.

[0021] Please see the appendix Figure 1 and attached Figure 5 The inner wall of the positioning plate 17 is provided with multiple air outlets 18, and the inner wall of the positioning plate 17 is provided with multiple mounting holes 19 near the edge. The inner wall of the interior panel 12 is fixedly connected with multiple support ribs 21, and the inner wall of the interior panel 12 is fixedly connected with a reinforcing rod 22. The inner wall of the mounting hole 19 is slidably connected with a bolt 20, and the inner wall of the bolt 20 is threadedly connected to the inner wall of the interior panel 12. Specifically, the addition of components to the positioning plate 17 and the interior panel 12 further strengthens the fixation and functional compatibility. Multiple air outlets 18 on the inner wall of the positioning plate 17 can guide the airflow of the air duct 11 to ensure ventilation. Multiple mounting holes 19 on its edge cooperate with the sliding bolts 20 on the inner wall. The bolts 20 are threadedly connected to the inner wall of the interior panel 12 to firmly fix the two and prevent loosening. Multiple support ribs 21 and reinforcing rods 22 on the inner wall of the interior panel 12 can enhance the structural strength of the interior panel 12 itself, reduce deformation caused by external forces, and ensure the overall connection stability.

[0022] Working principle: During installation, the outer shell 3 of the inner wall of the mounting column 1 is fixed with a wedge-shaped groove 4. The compression spring 6 in the through hole 5 of the inner wall of the wedge groove 4 applies a pushing force to the sliding wedge block 7 in the groove. The positioning protrusion 8 on the front side of the wedge block 7 pushes the butterfly spring 9, causing the butterfly spring 9 to deform in the mounting boss 10, forming an elastic lock, which tightly connects the wedge block 7 with the mounting boss 10. The mounting boss 10 fixes the air duct 11, thereby stabilizing the connected interior panel 12. When subjected to external force, the compression spring 6 and the butterfly spring 9 buffer the force, and the wedge structure prevents loosening, ensuring the stability of the position of each component and avoiding deformation and displacement of the guard plate and interior panel. During installation, the bottom of the mounting plate 201 is fixed to the outer wall of the mounting column 1, providing a stable base for the mechanism. When the interior trim is squeezed by external force, the force is transmitted to the cross link 204. The cross link 204 rotates flexibly through the rotating shaft 203, which is rotatably connected to the inner wall of the limiting block 202, to adjust the support angle. At the same time, the first rotating disk 205 on the inner wall of the cross link 204 rotates around the connecting column 206, and the second rotating disk 207 at the top of the connecting column 206 rotates synchronously to ensure smooth multi-angle adjustment of the link. The spiral spring 208 on the outer wall of the connecting column 206 deforms with the rotation of the link to absorb the impact of external force. After deformation, it releases the elastic force to assist the link in resetting, preventing the interior trim from deforming and shifting due to continuous external force.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
