[0048] Please refer to the drawings in the description Figures 1-7 The utility model provides a kind of automobile front longitudinal beam reinforcing plate:

[0049] The structure and function of front longitudinal beam and composite reinforcing plate

[0050] Front longitudinal beam 2: as the main force structure of automobile chassis, front longitudinal beam 2 plays a core role in vehicle safety structure, mainly used to absorb and transmit impact force, prevent body deformation.

[0051] Composite reinforcing plate 1: install in the inner side of front longitudinal beam 2, this plate is designed as composite structure, the torsional and bending strength of front longitudinal beam 2 is enhanced by the combination of inner side fixed plate 12 and special-shaped connecting plate 11.Composite structure reduces weight and improves material utilization efficiency simultaneously.

[0052] Inner side fixed plate 12: as connecting base, provide a smooth fixed plane, so that special-shaped connecting plate 11 can effectively cooperate with front longitudinal beam 2, form integrated reinforcing structure.

[0053] Special-shaped connecting plate 11: W-shaped design to provide higher stability and deformation resistance when subjected to lateral and longitudinal forces. The circular arc center design helps to disperse impact force and avoid damage caused by concentrated force, while the one-word design at both ends ensures close combination with the front longitudinal beam 2.

[0054] Installation and function description of positioning assembly

[0055] Positioning stud 31 and positioning nut 32: This pair of components work together to ensure that the special-shaped connecting plate is accurately fixed at the predetermined position of the front longitudinal beam 2. The installation position of the positioning stud 31 is particularly selected at the center position of the front longitudinal beam 2, which is a region with high mechanical performance requirements on vehicle structure. The fixing effect of the positioning stud 31 and the positioning nut 32 can ensure the connection strength between the composite reinforcement plate 1 and the front longitudinal beam 2.

[0056] Structure and installation details of limiting assembly

[0057] Limiting pin 41 and anti-falling screw cap 42: The limiting pin 41 is installed through deformation of the hole, which not only fixes the structure position, but also allows the structure to move moderately when subjected to external force to some extent, which increases the flexibility and impact bearing capacity of the overall structure. The use of anti-falling screw cap 42 is to ensure that the special-shaped connecting plate 11 can still be between the front longitudinal beam 2 and the inner fixed plate 12 after deformation.

[0058] Further description of the material and function of the elastic connecting piece

[0059] Elastic connecting piece 111: The selection of fluororubber material not only because of its excellent elasticity and temperature resistance, but also because of its excellent chemical corrosion resistance, which is very important in complex automotive operating environment. The distribution design of the elastic connecting piece considers maximizing the absorption and dispersion of impact force transmitted through the special-shaped connecting plate, effectively protecting the internal structure from damage.

[0060] Protection principle

[0061] Preliminary absorption of impact force: When the vehicle is subjected to front impact, the front longitudinal beam 2 as the main bearing structure first receives the collision force. The impact force is transmitted from the front longitudinal beam 2 to the composite reinforcement plate 1, especially through the inner fixed plate 12 installed on the inner side of the front longitudinal beam and the special-shaped connecting plate 11. The special-shaped connecting plate adopts W-shaped design, which deforms during impact, and multiple elastic connecting pieces 111 also buffer and deform during deformation. During deformation, the limiting assembly 4 slides inside the corresponding deformation hole to limit the state of the entire special-shaped connecting plate 11 during deformation.

[0062] Stability and deformation resistance enhancement: The design of the special-shaped connecting plate 11 provides higher stability and deformation resistance when subjected to lateral and longitudinal forces. This design feature ensures that the reinforcing plate can maintain the integrity of the structure and effectively support the front longitudinal beam during a collision.

[0063] The role of the positioning and limiting assembly: The positioning stud 31 and the positioning nut 32 ensure that the special-shaped connecting plate is accurately fixed at the predetermined position of the front longitudinal beam, enhancing the connection strength. The limiting pin 41 and the anti-falling screw cap 42 not only fix the structure position after the deformation hole is installed, but also allow the structure to move moderately when subjected to external forces, which increases the flexibility and impact bearing capacity of the overall structure.

[0064] The buffering effect of the elastic connecting piece: The elastic connecting piece 111 uses fluororubber material, which has excellent elasticity and temperature resistance, and can maximize the absorption and dispersion of the impact force when it is transmitted to the special-shaped connecting plate, thereby protecting the internal structure from damage.

[0065] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims.
