The outer side of the stop block is provided with an arc-shaped structure protruding outwards.

The right end part of the memory arm is inwards sunken to form an arc-shaped concave surface, the arc-shaped concave surface is a guide surface, and the stop block is connected with the guide surface in a sliding mode.

Adopt above-mentioned technical scheme, the utility model has the advantages of as follows:

1. the utility model discloses when electronic unblock signal sends or manual unblock action is accomplished, open arm and stop block around first connecting axle anticlockwise rotation, thereby make cardboard and stop block break away from the meshing, open the arm at the pivoted in-process, spacing post slides along the spacing groove and final card is established in the draw-in groove on the memory arm, the memory arm makes spacing post and draw-in groove chucking under the effect of third torsional spring, thereby carry on spacingly to opening the arm, avoid sending or manual unblock action completion back when electronic unblock signal, open arm and stop block return, the car back door receives external force and recloses, make cardboard and stop block re-meshing joint, cause the car back door to lock.

2. After the back door of the automobile is opened, the cardboard is around second connecting axle pivoted in-process, the dog of cardboard side slides and promotes the memory arm along jackshaft clockwise rotation along the guide surface on the memory arm, make spacing post and the draw-in groove on the opening arm break away from, open arm and stop block and rotate the return again around first connecting axle clockwise under the effect of first torsional spring, spacing post slides along the spacing groove, when the dog breaks away from with the memory arm along cardboard pivoted in-process, the memory arm rotates the return again around jackshaft anticlockwise under the effect of third torsional spring.

3. The outside of the stop block is arranged to be of an arc-shaped structure protruding outwards, the right end part of the memory arm is recessed inwards to form an arc-shaped concave surface, and the arc-shaped concave surface is a guide surface, so that the stop block is more smooth in sliding fit with the guide surface.
