Abstract
The invention relates to the technical field of vehicle structures, and provides a B-pillar reinforcement plate, a manufacturing method thereof, and a B-pillar assembly. The B-pillar reinforcement plate includes: an outer layer reinforcement plate with a body extending along the first direction, the body is provided with a weight-reduction hole extending along the first direction, the weight-reduction hole avoids the load-bearing area of the B-pillar reinforcement plate; the inner layer The reinforcement board is laid on the inner wall of the outer layer reinforcement board through fiber materials, and the inner layer reinforcement board is laid in sequence along its thickness direction: the first basic layer corresponding to the area where the main body is located, and the first layer corresponding to the area where the weight-reducing hole is located. The reinforced layup, the second reinforced layup corresponding to the area where the lightening hole and the bearing area are located, and the second basic layup corresponding to the area where the main body is located. In the present invention, the weight-reducing holes are provided on the outer layer reinforcement plate to realize the lightweight of the B-pillar reinforcement plate; the inner layer reinforcement plate is formed by laying multiple layers of fiber materials with variable thickness, and the weight-reduction holes and the load-bearing area are reinforced to realize the B-pillar reinforcement plate Strength and performance boost.
Description
technical field [0001] The invention relates to the technical field of vehicle structures, in particular to a B-pillar reinforcement plate, a manufacturing method thereof, and a B-pillar assembly. Background technique [0002] Vehicle safety is very important to vehicle construction. In the scene of vehicle side collision, the B-pillar is mainly used to bear the force to ensure that the vehicle does not undergo major deformation, thereby protecting the safety of passengers. [0003] The basic structure of the B-pillar includes the inner panel of the column and the reinforcing plate, among which the reinforcing plate is the main load-bearing component. The reinforced plate is usually stamped and formed by hot-formed steel or high-strength aluminum plate. The mainstream design includes: the plate is completely equal in thickness; the equal thickness plate is rolled into a continuously variable thickness plate according to the thickness requirement by a rolling mill; Welding ...
