Description

Technical Field

[0001] This application relates to the field of automotive longitudinal beam technology, and in particular to a multi-segment splicing automotive longitudinal beam structure. Background Technology

[0002] With increasingly stringent automotive safety requirements, traditional automotive longitudinal beam designs are increasingly facing a trade-off between strength and weight. Multi-segment splicing automotive longitudinal beam structures, as an innovative design solution, aim to optimize the vehicle's collision energy absorption characteristics, improve structural safety, and reduce vehicle weight. Traditional longitudinal beams are typically made of a single material or a monolithic structure, making it difficult to simultaneously achieve strength, stiffness, and weight. The multi-segment splicing design, by dividing the longitudinal beam into multiple segments and combining different materials and manufacturing processes, tailors the performance requirements for each segment. This design not only better disperses impact forces during a collision, improving crash resistance, but also achieves higher safety without adding excessive weight.

[0003] Currently, most multi-segment spliced ​​automotive longitudinal beam structures are supported by reinforcing ribs, resulting in poor protective effects and an inability to absorb the impact force generated by collisions. Utility Model Content

[0004] This application provides a multi-segment spliced ​​automotive longitudinal beam structure to solve the problem of poor protection and lack of ability to absorb the impact force generated by collision.

[0005] This application provides a multi-segment splicing automotive longitudinal beam structure, including a first beam segment. Damping adhesive is fixedly connected inside the first beam segment. A ceramic protective layer is fixedly connected inside the damping adhesive. A supporting partition is fixedly connected inside the ceramic protective layer. A metal woven mesh is fixedly connected to one side of the supporting partition. Ventilation holes are provided on the surface of the first beam segment. A first reinforcing rib is fixedly connected to one side of the first beam segment, and a second reinforcing rib is fixedly connected to one side of the first beam segment.

[0006] Preferably, a connecting plate one is fixedly connected to one side of the first beam segment, and a connecting plate two is fixedly connected to one side of the first beam segment.

[0007] Preferably, a bolt is slidably connected to one side of the connecting plate two, and a nut is threadedly connected to one side of the bolt.

[0008] Preferably, a spring washer is slidably connected to one side of the bolt, and an anti-slip washer is fixedly connected to one side of the bolt.

[0009] Preferably, a connecting plate three is slidably connected to the surface of the bolt, and a second beam segment is fixedly connected to one side of the connecting plate three.

[0010] Preferably, the surface of the second beam section is provided with ventilation holes, and a connecting plate is fixedly connected to one side of the second beam section.

[0011] Preferably, one side of the second beam section is fixedly connected with a reinforcing rib three, and one side of the second beam section is fixedly connected with a reinforcing rib four.

[0012] Beneficial effects: During use, the damping rubber buffers the impact of collisions, improving the protection of the longitudinal beams and extending their service life. The ceramic protective layer enhances the corrosion and high-temperature resistance of the longitudinal beams, and together with the damping rubber, it absorbs and disperses vibration energy, reducing noise during driving. The support baffles effectively resist bending and torsional stresses on the longitudinal beams during vehicle movement or collisions, preventing deformation or breakage. The metal woven mesh, together with the support baffles, disperses the energy generated by the collision when the support baffles break, further enhancing the protective capabilities of the longitudinal beams. This improves the vehicle's impact resistance in frontal and side collisions, reduces the risk of body deformation and damage to high-voltage circuits and battery packs, and enhances stability and integrity during collisions.

[0027] This utility model provides, for example Figure 1-4 The multi-segment splicing automotive longitudinal beam structure shown includes a first beam 1, a damping adhesive 2 fixedly connected inside the first beam 1, a ceramic protective layer 3 fixedly connected inside the damping adhesive 2, a supporting partition 4 fixedly connected inside the ceramic protective layer 3, a metal woven mesh 5 fixedly connected to one side of the supporting partition 4, ventilation holes provided on the surface of the first beam 1, a first reinforcing rib 6 fixedly connected to one side of the first beam 1, and a second reinforcing rib 7 fixedly connected to one side of the first beam 1.

[0028] In this system, the damping rubber 2 buffers the impact force generated by collisions, improving the protection of the longitudinal beams and extending their service life. The ceramic protective layer 3 enhances the corrosion resistance and high-temperature resistance of the longitudinal beams. Together with the damping rubber 2, it absorbs and disperses vibration energy, reducing noise generated during driving. The support baffle 4 effectively resists the bending and torsional stress of the longitudinal beams during vehicle movement or collisions, preventing deformation or breakage. The metal woven mesh 5, together with the support baffle 4, disperses the energy generated by the collision when the support baffle 4 breaks, improving the protection capability of the longitudinal beams. This enhances the protection capability of the longitudinal beams, improves the impact resistance of the vehicle in frontal and side collisions, reduces the risk of body deformation and damage to high-voltage circuits and battery packs, and improves stability and integrity during collisions.

[0029] Among them, a connecting plate 8 is fixedly connected to one side of the first beam 1, and a connecting plate 9 is fixedly connected to one side of the first beam 1.

[0030] Connecting plate 8 and connecting plate 9 facilitate the connection between longitudinal beams, making it easier to replace longitudinal beams when they are damaged, thus reducing maintenance costs.

[0031] Among them, a bolt 10 is slidably connected to one side of the connecting plate 2 9, and a nut 11 is threadedly connected to one side of the bolt 10.

[0032] Bolt 10 serves to connect connecting plate 2 9 and connecting plate 3 14, while nut 11, together with bolt 10, serves to fix connecting plate 2 9 and connecting plate 3 14.

[0033] Among them, a spring washer 12 is slidably connected to one side of the bolt 10, and an anti-slip washer 13 is fixedly connected to one side of the bolt 10.

[0034] The spring washer 12 absorbs some of the high-frequency vibration energy, reduces the risk of fatigue fracture of bolt 10, and extends its service life. The anti-slip washer 13 prevents bolt 10 from directly rubbing against the connecting plate and reduces surface wear.

[0035] Among them, the surface of bolt 10 is slidably connected to connecting plate 3 14, and one side of connecting plate 3 14 is fixedly connected to the second beam 15.

[0036] Connecting plate 3 (14) facilitates connection, while the second beam section (15) provides support and protection.

[0037] Ventilation holes are provided on the surface of the second beam section 15, and a connecting plate 16 is fixedly connected to one side of the second beam section 15.

[0038] The connecting plate 416 facilitates connection and installation, improving the ease of connection between bridges.

[0039] Among them, one side of the second beam 15 is fixedly connected with a reinforcing rib 3 17, and one side of the second beam 15 is fixedly connected with a reinforcing rib 4 18.

[0040] The reinforcing ribs 3.17 and 4.18 play a supporting role, improving the bridge's resistance to bending and torsion, and enhancing its support and protection.

[0041] Working Principle: When this multi-segment spliced ​​automotive longitudinal beam structure is used, the damping rubber 2 buffers the impact force generated by collisions, improving the protection of the longitudinal beam and extending its service life. The ceramic protective layer 3 improves the corrosion resistance and high temperature resistance of the longitudinal beam. Together with the damping rubber 2, it can absorb and disperse vibration energy, reducing noise generated during driving. The support baffle 4 effectively resists the bending and torsional stress of the longitudinal beam during vehicle driving or collisions, preventing deformation or breakage. The metal woven mesh 5, together with the support baffle 4, disperses the energy generated by the collision when the support baffle 4 breaks, improving the protection capability of the longitudinal beam. This enhances the vehicle's impact resistance in frontal and side collisions, reduces the risk of body deformation and damage to high-voltage circuits and battery packs, and improves stability and integrity during collisions.
