Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to a bidirectional fixing and installation structure of a B-pillar reinforcement. Background Art

[0002] Structural reinforcements are currently widely used in the automotive industry. They are characterized by light structure and high specific strength. They have become another composite material tool for body design engineers to provide structural support or reduce noise and vibration. In the body structure, reinforcements are mainly used in the vehicle's beams, pillars, crossbeams, key hinge points, door frames and other locations. The B-pillar (center pillar) of the car body plays a decisive role in the side collision safety performance of the vehicle. When a side collision occurs, the B-pillar is the first to be hit, so the B-pillar must have sufficiently high stiffness and strength.

[0003] The existing automobile B-pillar reinforcement structure, in order to improve the side impact and top pressure performance, will continuously increase the number and thickness of sheet metal at the B-pillar position, which increases the overall mass and does not meet the requirements of lightweight automobiles. At the same time, the B-pillar reinforcement cannot play a sound insulation effect, and the loud noise outside can be heard inside the car, affecting the driving experience of the vehicle.

[0023] The utility model is further described in detail below:

[0024] like Figures 1 to 5 As shown, the utility model provides a bidirectional fixed installation structure of a B-pillar reinforcement, including a B-pillar reinforcement plate 1, the B-pillar reinforcement plate 1 includes a reinforcement plate body 11, an inner side of the reinforcement plate body 11 is provided with an embedded groove 12, an edge of the embedded groove 12 is provided with a snap-fit ​​groove 13, an inner lining component 2 and a sound insulation component 4 are movably installed inside the embedded groove 12, a fixing bolt 3 penetrating the B-pillar reinforcement plate 1 is movably installed inside the lining component 2, and the top and bottom of the B-pillar reinforcement plate 1 are provided with mounting holes 5;

[0025] The lining assembly 2 includes an inner docking plate 21 , the outer side of the inner docking plate 21 is fixedly connected to a support inner edge 22 , and the inner side of the support inner edge 22 is fixedly connected to an inner reinforcing rib 23 .

[0026] The multiple inner reinforcing ribs 23 arranged on the inner side of the inner docking plate 21 of the lining component 2 not only help to reduce the weight of the lining component 2 and meet the requirements of lightweight automobiles, but also can significantly improve the structural strength and rigidity of the automobile B-pillar reinforcement plate 1 through its structural characteristics.

[0027] like Figure 4 As shown, the sound insulation component 4 includes a sound insulation felt 41 and a sound insulation cotton 42 . The sound insulation felt 41 is movably installed inside the embedded groove 12 , and the sound insulation cotton 42 is filled and arranged inside the embedded groove 12 .

[0028] The installation method of the sound insulation component 4 further optimizes its sound insulation effect. The contact surface between the sound insulation felt 41 and the embedded groove 12 is fixed to reduce the noise transmission caused by vibration. In addition, the material of the sound insulation cotton 42 is selected as a high-density sound-absorbing material, and its internal structure has been specially treated to have excellent sound absorption and sound insulation performance. At the same time, the outer shell of the sound insulation felt 41 is provided with an additional sound insulation film covering the outside of the sound insulation felt 41, which has good sound wave reflection and absorption characteristics, can effectively block high-frequency noise, and further improve the sound insulation effect.

[0029] like Figure 2 and Figure 3 As shown, a snap-fit ​​groove 13 is provided at the inner edge of the embedded groove 12 , and a connecting hole 14 is provided inside the snap-fit ​​groove 13 .

[0030] The fixing bolt 3 passes through the inner docking plate 21 and is threadedly connected to the inside of the connecting hole 14. The size of the clamping groove 13 set on the inner edge of the embedded groove 12 is slightly larger than the size of the embedded groove 12, and the fixing bolt 3 is installed in the connecting hole 14 to ensure a stable connection.

[0031] like Figure 3 and Figure 5 As shown, the support inner edge 22 is matched with the embedded groove 12 , and the support inner edge 22 is engaged with the inside of the embedded groove 12 .

[0032] The surface of the support inner edge 22 is polished to ensure that the contact surface with the embedded groove 12 is smooth and free of burrs, thereby providing stable supporting force. In order to enhance the reliability of the connection, the edge of the embedded groove 12 is designed with a chamfer so that the support inner edge 22 can smoothly transition when engaged, avoiding stress concentration and improving the overall strength and rigidity. The carefully designed matching structure of the support inner edge 22 and the embedded groove 12 not only ensures the stability and reliability of the component, but also greatly improves the convenience of installation and maintenance.

[0033] like Figure 3 As shown, the inner reinforcing rib 23 is welded to the inner side of the supporting inner edge 22, and the inner reinforcing rib 23 is arranged in a "Z" shape.

[0034] The inner reinforcing ribs 23 are welded to the inner side of the support inner edge 22. The inner reinforcing ribs 23 are arranged in a "Z" shape, which not only increases the rigidity of the structure but also effectively disperses the stress concentration points, thereby improving the overall bearing capacity. Transition sections can be set at both ends of the inner reinforcing ribs 23 to smoothly connect the support inner edge 22 and the inner reinforcing ribs 23, thereby reducing stress concentration and improving the fatigue life of the structure.

[0035] like Figure 5 As shown, the sound insulation cotton 42 is arranged on the inner side of the sound insulation felt 41 , the inner reinforcing ribs 23 abut against the outer side of the sound insulation felt 41 , and the sound insulation cotton 42 is filled inside the inner reinforcing ribs 23 .

[0036] The material of the sound insulation cotton 42 is selected to have high density and excellent sound absorption performance. A certain cavity is formed between the sound insulation felt 41 and the internal reinforcing ribs 23, which helps to further absorb and isolate noise. The outside of the sound insulation cotton 42 can also be covered with sound insulation cloth, which can prevent the fibers of the sound insulation cotton 42 from falling off, and can also reflect and absorb noise to a certain extent.

[0037] like Figure 5 As shown, an adhesive layer is provided inside the embedded groove 12 , and the sound insulation felt 41 is bonded and connected to the inner side of the embedded groove 12 .

[0038] The adhesive layer is provided to connect with the sound insulation felt 41, so that installation is facilitated and noise can be effectively reduced.

[0039] The working principle of the bidirectional fixed installation structure of the B-pillar reinforcement is described in detail below.

[0040] like Figures 1 to 5 As shown, first, the sound insulation felt 41 is manually set inside the embedded groove 12 set on the inner side of the reinforcing plate body 11, and is fixed to the inside of the embedded groove 12 by using the adhesive layer set inside the embedded groove 12, and then the sound insulation cotton 42 corresponding to the shape of the embedded groove 12 is inserted into the inner side of the support inner edge 22, and the support inner edge 22 is inserted into the embedded groove 12 corresponding to the inner side of the reinforcing plate body 11, so that the inner docking plate 21 is engaged with the inner side of the engagement groove 13, and the inner docking plate 21 and the reinforcing plate body 11 are fastened together by using the fixing bolts 3 to pass through the inner docking plate 21 and threadedly installed in the connecting hole 14, and the inner docking plate 21 and the reinforcing plate body 11 are fastened together, and the sound insulation cotton 42 is squeezed and filled into the support inner edge 22 and expanded on the inner side of the inner reinforcing rib 23, and is installed in the frame through the mounting holes 5 set in the upper and lower parts of the reinforcing plate body 11, and can be installed and fixed corresponding to other accessories of the reinforcing plate body 11.
