Abstract
Description
Technical Field

[0002] Currently, more and more vehicles are equipped with structural reinforcement components to ensure the safety of the vehicle body. In the existing technology, the structural reinforcement components and the cavity sound insulation blocks are installed separately on the vehicle body, which requires additional openings in the vehicle body. It is difficult to meet the requirements of vehicle collision safety and air tightness at the same time.
[0003] For example, the Chinese invention patent specification CN 115520109 A, published on December 27, 2022, discloses a structure integrating a cavity sound-insulating block and a structural reinforcement. The structure includes a structural reinforcement body with protruding structures on both sides. A placement cavity is located inside the protruding structures, with both ends of the placement cavity communicating with the outside. A sound-insulating block is installed inside the placement cavity and is fitted to the cavity. A connecting groove is located inside the sound-insulating block, with the end of the connecting groove away from the structural reinforcement body communicating with the outside. Multiple sets of openings are located on the side of the connecting groove closest to the structural reinforcement body, and each set of openings has a snap-fit mechanism inside. This integrated structure of the cavity sound-insulating block and structural reinforcement uses a design that integrates the structural reinforcement body into the sound-insulating block, saving space, but resulting in a weaker sealing effect.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.
[0018] A structural reinforcement component integrated with a cavity sealing block structure is provided. The structural reinforcement component 1 is provided with a cavity sealing block 2, and the cavity sealing block 2 is attached to the outer surface of the structural reinforcement component 1. The structural reinforcement component 1 ensures the structural strength of the foundation, and the cavity sealing block 2 further strengthens the structural strength while also sealing gas and providing sound insulation.
[0019] Specifically, such as Figure 1 and Figure 3 As shown, the cavity sealing block 2 is provided with an overlapping structure 5; the overlapping structure 5 is located at the upper end of the cavity sealing block 2; the overlapping structure 5 includes a first overlap 51 and a second overlap 52; the first overlap 51 overlaps the second overlap 52; the first overlap 51 is provided with a first mounting hole 6, and the second overlap 52 is provided with a second mounting hole 10; the first mounting hole 6 and the second mounting hole 10 are connected; the overlapping structure 5 can effectively improve the sealing performance of the structure, and the first mounting hole 6 and the second mounting hole 10 facilitate the installation and positioning of the overlapping structure 5, thereby improving the installation efficiency of the workers.
[0020] Specifically, such as Figure 1 and Figure 3 As shown, both the first connector 51 and the second connector 52 are stepped structures. The stepped surfaces of the first connector 51 and the second connector 52 fit together, further improving the sealing performance of the structure.
[0021] Specifically, such as Figure 3 As shown, the structural reinforcement 1 is provided with a snap fastener 7 and a positioning hole 9; the positioning hole 9 is connected to the first mounting hole 6; one end of the snap fastener 7 passes through the first mounting hole 6, and the other end of the snap fastener 7 is located inside the positioning hole 9. This simplifies the assembly process and improves assembly efficiency. At the same time, using the snap fastener 7 can reduce costs, make the structure compact, and improve production efficiency.
[0022] Specifically, such as Figure 1 As shown, the cavity sealing block 2 is provided with a leakage hole 4; the leakage hole 4 is located at the lower end of the cavity sealing block 2, and the leakage hole 4 is a round hole structure or a square hole structure. The leakage hole 4 penetrates through the lower end of the cavity sealing block 2. The function of the leakage hole 4 is to filter out residual electrophoresis after the car body passes through the coating electrophoresis pool, thereby improving the service life of the car body.
[0023] Specifically, such as Figure 2As shown, the structural reinforcement 1 has welding tabs 8 at both ends; the welding tabs 8 are connected to the structural reinforcement 1, and the function of the welding tabs 8 is to connect the structural reinforcement 1 to the external sheet metal.
[0024] Specifically, such as Figure 2 As shown, structural adhesive 3 is provided on the structural reinforcement 1, and the structural adhesive 3 is connected to the surface of the structural reinforcement 1. The structural adhesive 3 forms the structural reinforcement 1 and the external sheet metal into a whole to resist external impacts, maintain structural stability and prevent deformation, and thus play a reinforcing role and ensure the safety of the occupants.
[0025] Specifically, such as Figure 1 As shown, the leakage holes 4 are evenly distributed, which has the advantage of allowing for more thorough electrophoretic filtration of residual fluids and further extending the service life of the vehicle body.
[0026] Specifically, structural adhesive 3 is an epoxy resin structural adhesive with high bonding strength, capable of withstanding significant impacts, further enhancing the structural strength of structural reinforcement 1. Simultaneously, after being heated and melted in an oven, and then cooled and solidified upon exiting the oven, the structural strength is further enhanced, forming a dense cross-linked structure that integrates structural reinforcement 1 and the external sheet metal into a single unit, significantly improving sealing and structural strength. The skeleton of structural reinforcement 1 is a nylon skeleton, which is lightweight, has high structural strength, and a long service life.
[0027] Specifically, such as Figure 3 As shown, the end of the buckle 7 that passes through the mounting hole 6 has an arc-shaped structure, which can enhance the stability of the buckle 7 and prevent the buckle 7 from falling off; the buckle 7 and the structural reinforcement 1 are an integral structure, which facilitates the installation of the buckle 7 and reduces the installation cost of the buckle 7.
[0028] The working process of the integrated cavity sealing block structure of the structural reinforcement is as follows: the cavity sealing block 2 is integrated on the surface of the structural reinforcement 1. The car body first passes through the electrophoresis coating pool. The cavity sealing block 2 integrated on the structural reinforcement 1 has leakage holes 4, which can filter out residual electrophoresis. Then, after passing through the baking oven heating process, the outermost structural adhesive 3 foams at high temperature and bonds with the outer sheet metal. After leaving the baking oven, during the cooling process of the car body, the structural adhesive 3 cools and cures simultaneously, stably bonding the structural reinforcement 1 and the outer sheet metal into a whole, greatly improving the sealing performance and structural strength. After the cavity sealing block 2 foams, it fully connects to the outer sheet metal and is connected to the cured structural adhesive 3, blocking air flow and playing a role in sealing and sound insulation. The welding tabs 8 at both ends of the structural reinforcement 1 connect the structural reinforcement 1 and the outer sheet metal.
[0029] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
