[0002] In the automotive manufacturing sector, with the increasing demands for fuel economy and environmental friendliness, lightweighting has become an important development trend.

[0003] Chinese patent application CN205930914U discloses a lightweight structure for a car rear side panel reinforcement plate. This patent achieves a more reasonable structural layout without increasing weight, effectively dispersing the loads from the shock absorber and rear impact input, improving the force decomposition and absorption capacity, enhancing collision safety performance, and realizing lightweighting and cost reduction.

[0004] When using the aforementioned patent, we found that the device mainly focuses on optimizing the stress distribution through structural layout, but it is insufficient in terms of strength, sound insulation, heat insulation, corrosion resistance, and other performance aspects, making it difficult to meet the diverse usage requirements. Therefore, we proposed a lightweight structure for the rear side panel reinforcement of automobiles. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 , Figure 2 A lightweight structure for a rear side panel reinforcement plate of an automobile includes a rear side panel reinforcement plate body 1. The rear side panel reinforcement plate body 1 is made of high-strength lightweight metal materials, such as aluminum alloy or magnesium alloy. The interior of the rear side panel reinforcement plate body 1 is a hollow cavity. This hollow design can effectively reduce the weight of the reinforcement plate without significantly reducing its strength. A fixing seat 2 is fixed on the inner wall of the rear side panel reinforcement plate body 1. A support mechanism 3 for supporting the interior of the rear side panel reinforcement plate body 1 is installed on the fixing seat 2. The support mechanism 3 is mainly located in the areas of the rear side panel reinforcement plate body 1 where the stress is relatively high. The rear side panel reinforcement plate body 1 is equipped with reinforcing ribs 5 inside. The reinforcing ribs 5 are arranged in different ways such as crisscrossing, grid, or radial, which can further enhance the strength of the rear side panel reinforcement plate body 1. Sound insulation foam is filled between the reinforcing ribs 1. Sound insulation cotton 6 is provided on the inner wall of the rear side panel reinforcement plate body 1. The combination of sound insulation foam and sound insulation cotton can effectively block external noise from entering the vehicle and improve the quietness of the vehicle. The rear side panel reinforcement plate body 1 is provided with mounting holes 7, which facilitates the installation of the rear side panel reinforcement plate body 1 to the corresponding position on the car body.

[0023] Reference Figure 3 The support mechanism 3 includes a fixed rod 31, sliding sleeves 32, springs 33, a support rod 34, and a support plate 35. The fixed rod 31 is fixed inside the fixed base 2. Two sliding sleeves 32 are slidably sleeved on the fixed rod 31. The fixed base 2 has a sliding groove inside, and the sliding sleeves 32 are slidably installed in the sliding groove. A spring 33 connects the sliding sleeves 32 and the fixed base 2. The spring 33 is sleeved on the fixed rod 31. The side of the sliding sleeve 32 is hinged to the support plate 35 through the support rod 34. The rear side reinforcement plate body 1 is equipped with... Telescopic rod 4 is connected to support plate 35. When the rear side panel reinforcement plate body 1 is impacted by external force, the force will be transmitted to support plate 35. Support plate 35 pushes sliding sleeve 32 to slide on fixed rod 31 through support rod 34 and compresses spring 33, so that spring 33 is subjected to force and produces elastic deformation to absorb and buffer external force, reducing the impact force transmitted to rear side panel reinforcement plate body 1, thereby ensuring that the rear side panel reinforcement plate has sufficient strength and impact resistance to meet the safety and stability requirements of automobile body structure.

[0024] Reference Figure 4The surface of the rear side reinforcement plate body 1 is provided with an anti-corrosion coating 8, a heat insulation coating 9, and a wear-resistant coating 10. The coatings are arranged in order from the inside to the outside. The anti-corrosion coating 8 uses polyurethane anti-corrosion paint to prevent oxidation corrosion and electrochemical corrosion of the reinforcement plate and extend the service life of the reinforcement plate. The heat insulation coating 9 uses ceramic hollow microsphere composite heat insulation material, which can reflect solar radiation heat and reduce the thermal conductivity of the coating itself, effectively blocking the heat generated by the engine and other components from being transferred to the vehicle interior. The wear-resistant coating 10 uses tungsten carbide wear-resistant coating, which has high hardness and wear resistance and can effectively resist daily wear such as sand and gravel impact and scratches.

[0025] Working principle: By designing the rear side panel reinforcement plate body 1 as a hollow cavity structure, combined with the internal reinforcing ribs 5 and support mechanism 3, the weight can be reduced while ensuring that the rear side panel reinforcement plate has sufficient strength and impact resistance to meet the safety and stability requirements of the car body structure. The sound-insulating foam filled between the reinforcing ribs 5 and the sound-insulating cotton 6 on the inner wall can effectively block noise and create a quiet and comfortable driving environment. The anti-corrosion coating 8, heat-insulating coating 9 and wear-resistant coating 10 on the surface provide anti-corrosion, heat insulation and other functions respectively. The rear side panel reinforcement plate is protected in terms of wear resistance, etc., to extend its service life and improve its performance. When the rear side panel reinforcement plate body 1 is impacted by external force, the force will be transmitted to the support plate 35. The support plate 35 pushes the sliding sleeve 32 to slide on the fixed rod 31 through the support rod 34 and compresses the spring 33. The spring 33 is subjected to force and produces elastic deformation to absorb and buffer the external force, reducing the impact force transmitted to the rear side panel reinforcement plate body 1. This ensures that the rear side panel reinforcement plate has sufficient strength and impact resistance to meet the safety and stability requirements of the automobile body structure.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
