Strengthening structure of sliding door for vehicle

Abstract

The invention provides a strengthening structure of sliding door for vehicle, which includes a rigid part comprising an upper and a lower strengthening member, and prevents the post-slide door from moving toward external side by maintaining the clamping between a buckle and a striker of a latch. A beam (24) that extends along front and back direction of the vehicle is set on a door inner plate (21) of the post-slide door (2); a buckle (27) if set on front of the door inner plate (21); the striker of a latch (41) is set on a vertical wall (4a) of a middle pillar (4). When applying force to the post-slide door (2) from inner side of a carriage, the buckle (27) is clamped and held by the striker of a latch (41) at the front side of the post-slide door (2); the lower part of an upper strengthening member (4) and a lower strengthening member (6) are bonded together in an overlapping way around the buckle (27); position of the bonding part is configured as high as the beam (24) when watching from the front.

Description

technical field [0001] The present invention relates to a vehicle sliding door reinforcement structure capable of increasing the holding strength for holding a front side portion of the rear sliding door when a load from the inside of the cabin is applied to the rear sliding door toward the outside of the vehicle compartment. Background technique [0002] Conventionally, a rear sliding door that opens or closes a door opening on the side of the vehicle body by sliding in the vehicle front-rear direction is provided on the side surface of the vehicle body, and the rear sliding door is disposed behind the front door. [0003] In a vehicle equipped with the above-mentioned rear sliding door, a fastener is provided on the front portion of the door inner panel constituting the rear sliding door, and on the vertical wall surface of the center pillar facing the door opening, a fastener is provided corresponding to the fastener. A striker is protruded from the ground (for example, r...

AI Technical Summary

Problems solved by technology

In the case of such deformation as described above, the engagement between the fastener and the striker deforms in the direction of disengagement, so there may be loosening of the engagement of the two (movement of the fixing point of the fastener due to misalignment) or release of both. The hidden danger of the card

In order to reduce the deformation of the fastener, it is necessary to greatly increase the rigidity of the door inner panel by providing a reinforcing member, so it is difficult to avoid an increase in weight and cost
