The lower column section is connected to the lower end of the upper column section, the reinforcement structure is provided on the upper column section, and the energy-absorbing structure is provided on the lower column section to deform and absorb energy when the B-pillar is impacted. The thickness of the upper column section is greater than that of the lower column section, and the tensile strength of the upper column section is greater than that of the lower column section. In the prior art, side impact safety is typically improved by increasing the thickness of the B-pillar sheet material itself or by adding to the internal structure of the B-pillar. A strong impact on the side of the automobile can cause the B-pillar to severely dent or even break at the middle and lower ends.
[0004] Therefore, those skilled in the art urgently need to provide a car B-pillar that strengthens collision strength. Utility Model Content
[0005] The purpose of the utility model is to provide a multifunctional automobile B-pillar side impact reinforcement structure, which can enhance the collision strength of the B-pillar and effectively reduce the risk of the B-pillar sinking too much into the car and breaking.
[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a multifunctional automobile B-pillar side impact reinforcement structure, comprising a B-pillar and reinforcement ribs;

Obviously, the drawings described below are merely embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.
[0019] Figure 1 The accompanying drawing is a schematic diagram of the main structure of a multifunctional automobile B-pillar side impact reinforcement structure of the present invention.
[0020] Among them, 1 is the B-pillar; 2 is the car floor; 3 is the reinforcement rib; 4 is the storage opening; 5 is the box door; 6 is the hinge; 7 is the pin shaft; 8 is the clip strip; 9 is the seat. DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figure 1 A multifunctional automotive B-pillar side impact reinforcement structure is shown, comprising a B-pillar 1 and a reinforcing rib 3. The reinforcing rib 3 is fixedly connected between two B-pillars 1 and located at the lower ends of the B-pillars 1. The reinforcing rib 3 is arranged parallel to the vehicle floor 2, and the lower end of the reinforcing rib 3 is fixedly connected to the vehicle floor 2. The reinforcing rib 3 has a storage opening 4 on its surface facing the rear seat. Specifically, the B-pillar 1 and the reinforcing rib 3 are treated as a whole. While the B-pillar 1 remains the same, the reinforcing rib 3 is added. The height of the junction between the reinforcing rib 3 and the B-pillar 1 from the ground meets the height of most vehicles in side impacts. In the event of a side impact or a rollover, the reinforcing rib 3 effectively reduces the denting of the B-pillar 1 during a collision, ensuring space for rear passengers in the event of a traffic accident and increasing the chances of survival or escape. The reinforcing rib 3 is hollow inside, and the storage opening 4 can accommodate commonly used items, providing storage. The reinforcing rib 3 also provides a footrest for rear passengers.
[0023] In an exemplary embodiment, Figure 1 As shown, the cross section of the reinforcement rib 3 is rectangular. Specifically, the two surfaces of the reinforcement rib 3 connecting the two ends of the B-pillar 1 are square, ensuring that after a side impact, the other four surfaces of the cuboid are evenly stressed and not easily deformed.
[0024] In an exemplary embodiment, Figure 1 As shown, the reinforcing rib 3 is an integrally formed steel plate, and the connection between the reinforcing rib 3 and the B-pillar 1 is argon arc welded or arc welded. Specifically, the integrally formed reinforcing rib 3 ensures the strength of the steel plate, and the weld between the reinforcing rib 3 and the B-pillar 1 is treated with anti-corrosion and anti-rust treatment to ensure the weld strength of the connection after long-term use.
[0025] In an exemplary embodiment, Figure 1As shown, the thickness of the steel plate of the reinforcing rib 3 is 0.2-0.8 cm. Specifically, as one skilled in the art will appreciate, a 0.2 cm thick steel plate already has a certain impact resistance and can effectively reduce the degree of B-pillar denting. Alternatively, the reinforcing rib 3 can be made of an aluminum alloy plate with a thickness of 0.3-1 cm. As one skilled in the art will appreciate, a 0.3 cm thick aluminum alloy plate already has a certain impact resistance and can effectively reduce the degree of B-pillar denting.
[0026] In an exemplary embodiment, Figure 1 As shown, the height from the upper surface of the reinforcing rib 3 to the vehicle floor 2 is 8-23 cm. During use, space must be ensured for the driver's and passenger's seats to move forward and backward. Therefore, as one skilled in the art will appreciate, the height from the highest point of the reinforcing rib to the vehicle floor varies depending on the specific vehicle model. For example, the height from the upper surface of the reinforcing rib 3 to the vehicle floor 2 can be set at 8-10 cm for sedans, 9-13 cm for small SUVs, 12-18 cm for medium-to-large SUVs, and 15-23 cm for large off-road vehicles or vans.
[0027] In an exemplary embodiment, Figure 1 As shown, there are two storage openings 4, and the two storage openings 4 are symmetrical. The two storage openings 4 can provide more storage space, and the storage openings 4 are symmetrically distributed, which makes it more convenient for passengers in the back row to take and put items.
[0028] In an exemplary embodiment, Figure 1 As shown, the storage opening 4 is provided with a door 5 adapted to the storage opening 4. One end of a hinge 6 is fixedly connected to the outer side of the door 5, and the other end of the hinge 6 is fixedly connected to the reinforcing rib 3. Specifically, the door 5 opens toward the rear seat. The installation of the door 5 allows the items inside the storage opening to be concealed, making the appearance more beautiful and neat.
[0029] In an exemplary embodiment, Figure 1 As shown, the door 5 is provided with a pin 7, to which a clip 8 is hingedly connected; the reinforcing rib 3 is fixedly provided with a clip seat 9 that matches the clip 8. Specifically, during vehicle driving, bumps are inevitable. The addition of the pin 7, clip 8, and clip seat 9 to secure the door can prevent the door 5 from making noises due to bumps. During use, the clip 8 is moved to engage the clip seat 9 to close the storage opening 4 and secure the door 5. The clip 8 is moved in the opposite direction to open the door 5 and allow items to be taken in and out.
