Description

Technical Field

[0001] The utility model relates to the technical field of automobile B-pillars, in particular to a novel automobile B-pillar reinforcement plate structure. Background Art

[0002] The B-pillar of a car is a vertical support structure on the side of the vehicle, located between the front door and the rear door. It is an important part of the body structure. The B-pillar is usually made of steel or other high-strength materials to provide the necessary body rigidity and safety, and usually contains internal reinforcement structures such as ribs or foam filling to increase its bending and impact resistance. It can provide the strength and rigidity of the body, support the roof structure of the vehicle, and withstand the force of side collisions and vehicle rollovers. It also provides a fixing point for the vehicle door, allowing the door to open and close smoothly, and provides a safe interior space.

[0003] In order to improve the supporting strength of the existing automobile B-pillar, a reinforcement plate structure is usually added. However, the reinforcement plate structure is usually made of high-strength steel formed in one piece. When a collision occurs, the energy absorption effect is poor, which can easily cause the B-pillar to break and penetrate into the car, thereby injuring the driver's head.

[0004] To this end, we proposed a new B-pillar reinforcement plate structure for automobiles. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a first reinforcing plate. When a side collision occurs in a vehicle, the first reinforcing plate is designed in sections so that there is enough buffer space between the upper reinforcing plate and the lower reinforcing plate to ensure the integrity of the upper reinforcing plate, avoid direct breakage of the first reinforcing plate, and avoid injury to the driver's head. The arc interface between the upper reinforcing plate and the lower reinforcing plate is welded to ensure the overall strength of the first reinforcing plate, and the strip block is clamped in the strip groove, and the corresponding welding process is performed to further ensure the overall strength of the first reinforcing plate.

[0015] 2. The utility model provides an energy-absorbing block between the upper reinforcing plate and the second reinforcing plate.

The first reinforcement plate 200 includes an upper reinforcement plate 201 and a lower reinforcement plate 202. An arc interface 203 is provided between the upper reinforcement plate 201 and the lower reinforcement plate 202, and the arc interface 203 is welded. When a side collision occurs on the vehicle, the segmented design of the first reinforcement plate 200 allows sufficient buffer space to be provided between the upper reinforcement plate 201 and the lower reinforcement plate 202, thereby ensuring the integrity of the upper reinforcement plate 201, avoiding direct breakage of the first reinforcement plate 200, and avoiding injury to the driver's head.

[0025] See also Figure 1-5 The upper reinforcing plate 201 and the lower reinforcing plate 202 are provided with strip grooves 204 on their surfaces for clamping the strip blocks 205. The strip blocks 205 are welded in the inner cavity of the strip grooves 204. By welding at the arc interface 203 between the upper reinforcing plate 201 and the lower reinforcing plate 202, the overall strength of the first reinforcing plate 200 is ensured, and the strip blocks 205 are clamped in the strip grooves 204, and corresponding welding processes are performed to further ensure the overall strength of the first reinforcing plate 200.

[0026] See also Figure 1-5 The tensile strength of the first reinforcement plate 200 is 1500MPa, and the wall thickness of the first reinforcement plate 200 is 2.50mm-3.20mm. It has higher strength and rigidity, can withstand greater tensile loads, and can achieve a lighter design, thereby reducing the weight of the entire structure and improving the fuel efficiency and performance of the vehicle. The tensile strength of the outer panel 100 is 500MPa, and the wall thickness of the outer panel 100 is 1.20mm-1.50mm, which is easier to process and form, and is convenient for complex shape processing. The tensile strength of the second reinforcement plate 300 is 1200MPa, and the wall thickness of the second reinforcement plate 300 is 1.5mm-1.8mm, which improves the overall strength of the B-pillar body 1.

[0027] In this embodiment: when in use, the outer panel 100, the first reinforcing plate 200 and the second reinforcing plate 300 are integrally welded and assembled, which can improve the overall strength of the B-pillar body 1 while reducing the weight of the entire structure and improving the fuel efficiency and performance of the vehicle; when a collision occurs on the side of the vehicle, the segmented design of the first reinforcing plate 200 allows sufficient buffer space to be provided between the upper reinforcing plate 201 and the lower reinforcing plate 202, thereby ensuring the integrity of the upper reinforcing plate 201, avoiding direct breakage of the first reinforcing plate 200, and avoiding injury to the driver's head; and by welding the arc interface 203 between the upper reinforcing plate 201 and the lower reinforcing plate 202, the overall strength of the first reinforcing plate 200 is ensured, and the strip block 205 is clamped in the strip groove 204, and the corresponding welding process is performed to further ensure the overall strength of the first reinforcing plate 200.

[0028] Example 2

[0029] See also Figure 1-4 The present embodiment further illustrates Example 1. In the figure, a plurality of slots 206 are provided on the side wall of the upper reinforcing plate 201 for connecting the energy absorbing block 301. A plurality of energy absorbing blocks 301 are welded on the side wall of the second reinforcing plate 300 for releasing the energy of the upper reinforcing plate 201 to ensure the integrity of the upper reinforcing plate 201. The other end of the energy absorbing block 301 is inserted into the slot 206. The energy absorbing block 301 is welded to the upper reinforcing plate 201. The energy absorbing block 301 is I-shaped. The tensile strength of the energy absorbing block 301 is 500 MPa, which has a good energy absorbing effect, thereby slowing down the collision process and protecting the safety of the vehicle and passengers.

[0030] In this embodiment: when in use, by setting an energy-absorbing block 301 between the upper reinforcing plate 201 and the second reinforcing plate 300, when a collision occurs, the collision energy received by the upper reinforcing plate 201 can be further absorbed and released through the deformation of the energy-absorbing block 301, thereby ensuring the integrity of the upper reinforcing plate 201 and preventing the driver and passengers from suffering head impacts.
