Description

Technical Field

[0001] This invention relates to the field of automotive body engineering and structural connection technology, and in particular to a modular anti-collision beam integrated isolation component and its assembly method. Background Technology

[0002] In the field of automotive body engineering and structural connection technology, the hybrid connection of aluminum alloy and high-strength steel heterogeneous metals is the mainstream technical solution to achieve both lightweight body and collision safety. Among them, the anti-collision beam, as a key safety component, has long faced a series of comprehensive technical problems caused by heterogeneous corrosion at the connection interface between its aluminum crossbeam and steel longitudinal beam. Existing technologies cannot effectively solve these problems, which seriously affect vehicle durability and driving safety. Heterogeneous corrosion at the steel-aluminum connection surface refers to the fact that direct contact between aluminum alloy beams and steel beams easily generates a galvanic cell effect, and steel bolts often become conductive "short circuit" bridges. When aluminum (Al) and steel (Fe) are in direct contact and exposed to a humid environment (electrolyte), due to the difference in their electrode potentials, a miniature galvanic cell will be formed. As a more reactive metal, aluminum will act as the anode and be rapidly corroded, leading to connection failure. Traditional sealing designs present irreconcilable contradictions. When a "dead seal" structure is used (i.e., the seal is in closed contact with the aluminum and steel surfaces), the temperature difference changes throughout the vehicle's operation and process can easily cause condensation in the connection gap, which cannot be discharged, resulting in "greenhouse corrosion." On the other hand, an open structure cannot prevent salt spray intrusion, which also induces interface corrosion. Furthermore, pure non-metallic gaskets are prone to plastic flow, i.e. creep, under the action of high bolt preload, which leads to loosening of the anti-collision beam connection and inability to maintain stable preload, seriously affecting the accuracy of FEM finite element simulation and vehicle collision safety performance, and failing to meet the requirements of anti-collision beam safety components for high compressive strength and high connection stability. Summary of the Invention

[0003] In view of this, the present invention aims to provide a modular anti-collision beam integrated isolation component and its assembly method, so as to overcome the failure defects caused by greenhouse corrosion at the aluminum-steel heterogeneous connection interface of the existing automotive anti-collision beam, and improve the long-term reliability and safety of the connection structure.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows: A modular anti-collision beam integrated isolation component includes: a gasket body made of an insulating polymer material, the gasket body having a first side for fitting an aluminum beam and a second side for fitting a steel beam, and further includes: A flow guiding structure, a sealing structure, and an insulating isolation structure are respectively provided on the first and second surfaces of the gasket body; The flow guiding structure includes a flow guiding groove with multiple segments of gradually changing curvature on the first surface and two gently sloping, large-radius circular arcs on the second surface. The curvature and arrangement of the guide grooves on both sides of the gasket body are different, and the guide grooves are only connected to the Venturi drain on the side of the gasket body where the Venturi drain is provided, and the other positions of the guide grooves do not extend to the outer edge of the gasket body. The sealing structure is arranged along the edge of the gasket body; An insulating isolation structure is provided in the bolt connection area of ​​the gasket body to form a continuous insulating isolation path when connected.

[0005] Furthermore, the gasket body is made of high-rigidity glass fiber reinforced polyamide; the Venturi drain outlets on the first and second sides are connected through micropores to achieve air pressure balance on both sides of the gasket body; the Venturi drain outlet adopts an inward-retracting and outward-expanding Venturi flare structure, and the outward-expanding part is the outer opening of the flow guide structure.

[0006] Furthermore, the first surface is provided with multiple segments of gradually curvature, arc-shaped guide grooves with three different curvature changes, gradually converging towards the central region of the first surface.

[0007] Furthermore, the second surface is provided with two gently sloping, large-radius arc guide channels; The depth of the guide groove in the thickness direction of the gasket body is less than the total thickness of the gasket body.

[0008] Furthermore, the sealing structure adopts a double-line layout and includes an inner sealing lip and an outer sealing lip with a height difference along the thickness direction. The outer sealing lip is used to form a first contact seal in the early stage of assembly, and the inner sealing lip forms a relatively closed airtight area after further compression. The height of the sealing structure is 0.2mm to 0.5mm above the main plane of the gasket body, and the width of the sealing structure is 0.5mm to 0.8mm.

[0009] Furthermore, the guide channel forms a non-linear, continuously changing tortuous path along the flow direction, and the path and the Venturi drain outlet constitute a one-way flow channel.

[0010] Furthermore, the insulating isolation structure includes: a first insulating liner coated with PA and a split insulating hole cover; the first insulating liner is formed by extending along the bolt connection hole of the gasket body and toward the assembly hole of the aluminum beam and the steel beam; the bolt passes through the first insulating liner; each split insulating hole cover includes a second insulating liner and an insulating flange that are interconnected; the second insulating liner is coaxially nested in the first insulating liner, and the insulating flange covers the beam contact surface where the bolt is locked.

[0011] Furthermore, the thickness of the gasket body ranges from 1.0 mm to 2.0 mm.

[0012] Furthermore, the thickness of the gasket body ranges from 2.0mm to 2.5mm. The modular anti-collision beam integrated isolation component also includes an embedded metal load-bearing core, which is located in the area of ​​the assembly holes of the aluminum beam and the steel beam and is used to press on the gasket body.

[0013] A modular anti-collision beam integrated isolation component assembly method includes the following steps: S1: Molding a gasket body, and integrally molding a sealing structure and a first insulating liner at the edge of the gasket body; S2: Molding a multi-segment gradually curvature arc-shaped guide channel on the first surface of the gasket body, and molding two gentle large-radius arc-shaped guide channels on the second surface, so that the curvature and arrangement of the guide channels on the two surfaces are different, and the guide channels only connect to the Venturi drain outlet side, and the rest of the area does not extend to the outer edge of the gasket body; S3: Molding a Venturi drain outlet and a micropore connecting the first surface and the second surface at the corresponding assembly position of the gasket body, the Venturi drain outlet adopts an inward-expanding flared mouth structure and opens outward; S4: Attaching the PA-coated first insulating liner and the split insulating hole cover of the insulating isolation structure together, so that the bolt connection area forms a three-dimensional full-domain insulation potential blockage of surface contact, hole inner wall, and bolt end; S5: Assembling the gasket body between the aluminum beam and the steel beam, and achieving double-layer interference sealing and insulation protection of the assembly interface through the sealing structure.

[0014] Compared with the prior art, the present invention can achieve the following beneficial effects: Firstly, an insulating isolation structure is adopted to achieve full-dimensional potential blocking of the aluminum beams, steel beams and bolt connection areas, including surfaces, holes and ends, thereby cutting off the electrochemical corrosion circuit of heterogeneous metals from the root and solving the problem of galvanic corrosion in aluminum-steel connections. Secondly, relying on the airflow structure, the negative pressure suction effect formed by the airflow of the vehicle actively discharges the water and water vapor at the interface, thus solving the contradiction of the traditional sealing of "dead sealing and water accumulation, open opening and salt spray", and eliminating the hidden danger of greenhouse corrosion. Thirdly, in this solution, the gasket body is made of high-rigidity glass fiber reinforced polyamide material, and the high load-bearing capacity can be set with an embedded metal load-bearing core, which effectively suppresses material creep under high preload, maintains connection stiffness and preload stability, and improves the durability and collision safety performance of the anti-collision beam structure. Fourthly, the sealing structure forms a double-layer sealing structure with outer ring protection and inner ring airtightness, which is compatible with microscopic defects on the metal surface, has high sealing and insulation reliability, and takes into account dustproof, waterproof and insulation protection.

[0015] Fifthly, the gasket body adopts differentiated curvature guide grooves on both sides to ensure structural strength while achieving interface fluid guidance and avoiding capillary water absorption and local water accumulation.

[0016] The overall design is modular and integrated, which makes assembly simple and positioning reliable, reduces the number of loose parts, is compatible with automated assembly, and improves production efficiency and assembly consistency. Attached Figure Description

[0025] This invention aims to provide a modular anti-collision beam integrated isolation component and its assembly method, to overcome the failure defects caused by greenhouse corrosion at the aluminum-steel heterogeneous connection interface of existing automotive anti-collision beams, and to improve the long-term reliability and safety of the connection structure. Please refer to the appendix. Figure 1-8 As shown, the overall structure implementation method is as follows: A modular anti-collision beam integrated isolation component includes: a gasket body 10 made of insulating polymer material, the gasket body 10 having a first surface 101 for fitting aluminum beam members and a second surface 102 for fitting steel beam members, and further includes: The flow guiding structure 100, sealing structure 200, and insulating isolation structure 300 work together to achieve insulation, sealing, drainage, and mechanical stability at the connection interface in order to ensure the best implementation effect. Among them, the flow guiding structure 100 and the insulating isolation structure 300 are the core functional structures for actually solving the failure defects caused by greenhouse corrosion in this application. In terms of specific configuration, the flow guiding structure 100 includes multiple flow guiding grooves 103 with gradually changing curvature and arc shape on the first surface 101, and two flow guiding grooves 103 with gentle large radius arcs on the second surface 102. The curvature and arrangement of the guide grooves 103 on both sides of the gasket body 10 are different, and the guide grooves 103 are only connected to the Venturi drain 104 on the side of the gasket body 10 where the Venturi drain 104 is provided. The other positions of the guide grooves 103 do not extend to the outer edge of the gasket body 10. The sealing structure 200 is arranged along the edge of the gasket body 10; An insulating isolation structure 300 is disposed in the bolt connection area of ​​the gasket body 10 and is used to form a continuous insulating isolation path in the connected state. That is, when the insulating isolation structure 300 connects the gasket body 10, the aluminum beam, and the steel beam, it achieves spatial potential blocking at the connection point.

[0026] In one specific embodiment, please refer to the appendix. Figure 1 , 2 As shown in Figure 3, the gasket body 10 is made of high-stiffness glass fiber reinforced polyamide; The Venturi drain 104 of the first surface 101 and the second surface 102 are connected through micropores 105 to achieve air pressure balance on the front and back sides of the gasket body 10. The Venturi drain outlet 104 adopts an inward-retracting and outward-expanding Venturi horn structure, and the outward-expanding part is the outer opening of the flow guide structure 100. The Venturi drain outlet 104 is always in the negative pressure side where the vehicle generates negative pressure, which is equivalent to active suction and realizing "self-breathing" dehumidification.

[0027] In one specific embodiment, please refer to the appendix. Figure 1 , 2 As shown in Figures 1 and 3, the first surface 101 is provided with multiple segments of gradually curvature and arc-shaped guide grooves 103 with three different curvature changes, which gradually converge towards the central region of the first surface 101. The different radii of curvature allow the fluid to form a continuously varying velocity or pressure drop distribution along the flow direction within the guide channel 103.

[0028] In one specific embodiment, please refer to the appendix. Figure 1 , 2 As shown in Figures 1 and 3, the second surface 102 is provided with two gently sloping, large-radius arc guide grooves 103; The guide groove 103 forms a non-through structure inside the gasket body 10, and its extension depth in the thickness direction is less than the total thickness of the gasket body 10.

[0029] As attached Figure 1 , 2 As shown in Figures 1 and 3, the flow guiding structure 100 includes multiple flow guiding grooves 103 with gradually changing curvature and arc shape on the first surface 101, and two flow guiding grooves 103 with gentle large-radius arcs on the second surface 102.

[0030] The curvature and arrangement of the guide grooves 103 on both sides of the gasket body 10 are different, and the guide grooves 103 are only connected to the Venturi drain 104 on the side of the gasket body 10 where the Venturi drain 104 is provided. The other positions of the guide grooves 103 do not extend to the outer edge of the gasket body 10.

[0031] The first surface 101 is provided with multiple segments of gradually curvature and arc-shaped guide grooves 103 with three different curvature changes, which gradually converge toward the central region of the first surface 101.

[0032] The sealing structure 200 adopts a double-line layout and includes an inner ring sealing lip and an outer ring sealing lip with a height difference along the thickness direction. The outer ring sealing lip is used to form a first contact seal at the initial stage of assembly, and the inner ring sealing lip forms a relatively closed airtight area after further compression. The design features are as follows: the height of the sealing structure 200 extends 0.2mm to 0.5mm above the main plane of the gasket body 10; The width of the sealing structure 200 ranges from 0.5 mm to 0.8 mm.

[0033] In one specific embodiment, please refer to the appendix. Figure 1 , 2 As shown in Figure 3, the flow channel 103 forms a non-linear, continuously changing tortuous path along the flow direction, and this path forms a one-way flow channel with the Venturi drain outlet 104; the non-linear, continuously changing tortuous path can be implemented by selecting an S-shaped labyrinth structure to improve the fluid guiding effect and ensure structural strength.

[0034] In one specific embodiment, please refer to the appendix. Figure 6 , 7As shown, the insulating isolation structure 300 includes: a first insulating liner 310 coated with PA and a split insulating hole cover 320, the split insulating hole cover 320 also being treated with PA insulating coating; the first insulating liner 310 is formed by extending along the bolt connection hole of the gasket body 10 towards the assembly hole 2 of the aluminum beam and the steel beam; the bolt 1 passes through the first insulating liner 310; each split insulating hole cover 320 includes a second insulating liner 322 and an insulating flange 321 connected to each other; the second insulating liner 322 is coaxially nested in the first insulating liner 310, and the insulating flange 321 covers the beam contact surface locked by the bolt 1.

[0035] For the final implementation of the insulation and isolation structure, please refer to the appendix. Figure 6 , 7 As shown in Figure 8, the insulating isolation structure 300 is used to block the spatial potential at the connection point when connecting the gasket body 10, the aluminum beam, and the steel beam (thus forming a three-dimensional full-domain insulating barrier of the surface, hole, and end).

[0036] The thickness of the gasket body 10 and the implementation method of the load-bearing structure are shown in the attached figure. Figure 1 , 2 As shown in Figures 1 and 3, the thickness of the gasket body 10 ranges from 1.0 mm to 2.0 mm, which meets the insulation, sealing and rigidity requirements of conventional connection conditions, and does not use an embedded metal load-bearing core 330. Another embodiment includes an embedded metal load-bearing core 330, as shown in the attached figure. Figure 6 , 7 As shown, the thickness of the gasket body 10 ranges from 2.0mm to 2.5mm. The embedded metal load-bearing core 330 is disposed in the area of ​​the assembly hole 2 of the aluminum beam and the steel beam and presses on the main body of the gasket body 10 to improve the creep resistance and structural stability under the bolt preload.

[0037] In the assembly and working process, the gasket body 10 is placed between the aluminum beam and the steel beam, and the first insulating liner 310 of the insulating isolation structure 300 with PA coating and the split insulating hole cover 320 are snapped together and then locked by bolt 1. During the locking process, the sealing structure 200 forms a double-layer interference seal; When the vehicle is in motion, the airflow at the interface creates a negative pressure "self-breathing" effect at the guide channel 103 and the Venturi drain outlet 104. The air pressure on both sides is balanced through the micropores 105, causing water and moisture accumulated at the interface to be discharged outwards along the guide channel and the Venturi drain outlet, achieving dynamic dehumidification and corrosion prevention. The above process is the modular anti-collision beam integrated isolation component assembly method mentioned in this application, including the following steps: S1: Molded gasket body 10, and integrally formed sealing structure 200 and first insulating liner 310 at the edge of gasket body 10; S2: A multi-segment gradually curvature arc-shaped guide channel 103 is formed on the first surface 101 of the gasket body 10, and two gentle large-radius arc-shaped guide channels 103 are formed on the second surface 102, so that the curvature and arrangement of the two guide channels 103 are different, and the guide channels 103 are only connected to the Venturi drain outlet 104 on the side, and the rest of the area does not extend to the outer edge of the gasket body 10. S3: A Venturi drain 104 and a microhole 105 connecting the first surface 101 and the second surface 102 are formed at the corresponding assembly position of the gasket body 10. The Venturi drain 104 adopts a flared structure that is narrowed inward and expanded outward and opens outward. S4: The PA-coated first insulating liner 310 and the split insulating hole cover 320 of the insulating isolation structure 300 are snapped together to form a three-dimensional global insulating potential blockage of the bolt connection area, including surface contact, hole inner wall and bolt end. S5: The gasket body 10 is assembled between the aluminum beam and the steel beam, and the double-layer interference seal and insulation protection of the assembly interface are achieved through the sealing structure 200.

[0038] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this invention disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this invention can be achieved, and this is not limited herein.

[0039] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
