The invention discloses a connection structure between a dash panel and a front floor passage. The dash panel assembly and the front floor assembly form a passage. A reinforced cavity, the rear part of the channel is located at the lower part of the front floor assembly, and a second reinforced cavity facing upward in the direction of Y is provided, and the dash panel assembly and the front floor assembly are provided with A reinforcement device, the reinforcement device forms at least two three-layer plate welds along the X direction between the dash panel assembly and the front floor assembly and the dash panel assembly and the front floor assembly place. The connection structure between the dash panel and the front floor passage of the present invention has a simple structure and low manufacturing cost, and can be applied to integral and split front floor assemblies at the same time. The deformation is small and the safety performance is good.
Description
technical field [0001] The invention relates to a channel, in particular to a connection structure between a dash board and a front floor channel. Background technique [0002] At present, in some models with higher collision star ratings (four stars and above), in order to reduce the collision intrusion of the dash panel and ensure the normal operation of the airbag control module (ECU) 5, the dash panel assembly 1 The channel connection area with the front floor assembly 2 adopts a reinforced structure, such as: the channel sheet metal adopts high-strength steel, and the channel connection area adds a reinforcement plate 3 ( Figure 1 ) and even beams. The main disadvantages are: the high-strength steel used in the central channel is expensive; the use of different materials for the central channel and the floor body is only suitable for the block-type front floor assembly, not for the integral floor structure; the overlapping area between the front panel and the front flo...
