Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to a segmented B-pillar reinforcement plate structure. Background Art
[0002] As an important component of the side reinforcement plate, the B-pillar of a car is located between the front door and the rear door. It can effectively protect the occupants of the car in the event of a side collision and plays a vital role in the absorption and transmission of energy in a side collision. However, current commercial vehicle regulations do not have mandatory requirements for side collisions. The B-pillar reinforcement plates of most models are designed to be small in size, and only the door locks, limiters and seat belt installation points are strengthened, without considering whether they can meet higher collision requirements. However, with the expansion of the market, various car companies are increasing competition in overseas markets. Many customers have other requirements for the side collision test of commercial vehicles. It is necessary to adjust the structure of the B-pillar reinforcement plate of existing commercial vehicles so that it can be applied to some existing local reinforcement structures as well as other commercial vehicles with higher requirements for side collisions. Therefore, it is necessary to provide a B-pillar reinforcement plate structure that can provide local reinforcement or overall penetration. Utility Model Content
[0003] The utility model aims to provide a segmented B-pillar reinforcement plate structure, so as to provide a B-pillar reinforcement plate structure capable of providing local reinforcement or overall penetration.
[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a segmented B-pillar reinforcement plate structure, including an upper reinforcement plate, an upper reinforcement connecting plate, a lower reinforcement plate and a lower reinforcement connecting plate which can be welded and fixed in sequence, the lower reinforcement plate supports the lower part of the vehicle door, the upper reinforcement plate is provided with a seat belt connection hole, and the lower reinforcement connecting plate is used to connect the lower reinforcement plate to the vehicle frame.
[0005] The beneficial effects of this program are:
[0006] This patent divides the B-pillar reinforcement plate assembly into multiple parts, namely the upper reinforcement plate, the upper reinforcement connecting plate, the lower reinforcement plate, and the lower reinforcement connecting plate. This allows for switching the B-pillar strength requirements based on different vehicle models, effectively reducing development costs and shortening development cycles. The upper reinforcement plate is located at the upper part of the B-pillar. The upper reinforcement connecting plate is used to connect the upper reinforcement plate and the lower reinforcement plate, primarily for strengthening the strength of the seatbelt connection area. It can be selectively welded as needed to form a through-type structure to enhance overall strength. The lower reinforcement plate is located at the lower part of the B-pillar and primarily supports the lower part of the door, enhancing the impact resistance of the vehicle side. The lower reinforcement connecting plate is used to connect the lower reinforcement plate to the frame, ensuring the overall rigidity and stability of the B-pillar and body. For traditional vehicles that do not have side collision requirements, it is only necessary to weld the upper and lower reinforcement plates and strengthen key installation points such as seat belts and buckles, which can effectively reduce the development cost of the entire vehicle; for vehicles that have requirements for vehicle side collision strength, a through-type B-pillar reinforcement plate assembly is used, and the upper reinforcement plate, upper reinforcement connecting plate, lower reinforcement plate and lower reinforcement connecting plate are welded and fixed in sequence to improve the strength of the B-pillar and ensure the vehicle's side collision resistance.
[0007] Preferably, as an improvement, the lower reinforcement plate is stamped with a reinforcement protrusion structure.
[0008] The beneficial effects are: in the event of a side collision, the reinforced protrusion structure can act as a buffer, evenly dispersing the collision energy around the protrusion, thereby improving the overall rigidity and impact resistance of the lower reinforcement plate; the use of a stamped protrusion design can increase strength without significantly increasing weight, thereby achieving a lightweight design.
[0009] Preferably, as an improvement, both ends of the upper reinforcing connecting plate are punched with sunken grooves.
[0010] The beneficial effects are: the two sunken grooves are respectively fitted with the ends of the upper reinforcing plate and the lower reinforcing plate and then welded and fixed. The design of the sunken grooves allows for a larger contact area between the upper reinforcing connecting plate and the upper and lower reinforcing plates. The upper reinforcing connecting plate is tightly fitted with the ends of the upper and lower reinforcing plates through the sunken grooves at both ends, and then welded and fixed, thereby improving the bending resistance of the B-pillar.
[0011] Preferably, as an improvement, the upper reinforcing plate, the upper reinforcing connecting plate, the lower reinforcing plate and the lower reinforcing connecting plate are made of steel plates.
[0012] The beneficial effects are: the steel plate has excellent strength and rigidity, and can provide reliable support and impact resistance for the B-pillar. Especially when the vehicle collides from the side, the steel plate material can effectively absorb and disperse the impact energy, protecting the safety of the passengers in the vehicle.
[0013] Preferably, as an improvement, a seat belt retractor mounting hole is provided in the lower reinforcing connecting plate.
[0014] The beneficial effect is that the seat belt retractor is installed on the lower reinforcement connecting plate, which effectively utilizes the overall strength of the B-pillar to ensure better occupant restraint effect in the event of a side collision of the vehicle.
[0015] Preferably, as an improvement, the connections between the upper reinforcing plate, the upper reinforcing connecting plate, the lower reinforcing plate and the lower reinforcing connecting plate are further provided with rivet holes for double-row self-piercing riveting, and the upper and lower rows of rivet holes are staggered.
[0016] The beneficial effects are: double-row self-pierce riveting can provide a larger contact area and more connection points, effectively improving the bonding strength between the upper and lower reinforcing plates and the connecting plates, and avoiding the impact of loose connections on safety performance during collisions or long-term use.
