Abstract

The invention discloses a connecting assembly. The connecting assembly comprises an upper connecting rod piece and a four-connecting-rod hinge structure. The four-connecting-rod hinge structure comprises a lower connecting rod piece, one end of the upper connecting rod piece is hinged to the lower connecting rod piece through a hinge shaft, and the upper connecting rod piece has a locking state and an upspring state. A lock pin is arranged on the upper connecting rod piece and provided with a clamp groove and a preloaded spring. A mounting plate is arranged on the lower connecting rod piece and extends upwards to form a matching hole. A clamp plate is hinged to the position, at one side of the matching hole, of the mounting plate, the position, close to one side of the matching hole, of the clamp plate extends to form a clamping portion, and an open portion is formed on the wall of the matching hole. A drive assembly used for driving the clamp plate to rotate is arranged on the mounting plate, and the clamping portion and the clamp groove can match or be separated along with rotation of the clamp plate. When the clamping portion and the clamp groove match, the lock pin is locked in the matching hole, and the upper connecting rod piece is in the locking state. When the clamping portion and the clamp groove are separated, the lock pin is separated out of the matching hole, and the upper connecting rod piece is in the upspring state.

Description

technical field [0001] The invention relates to the technical field of connecting components of an automobile engine cover, in particular to a connection assembly for connecting an engine cover and a vehicle body. Background technique [0002] Pedestrian protection is now an important topic for all vehicle manufacturers when it comes to improving passive safety, vehicle general layout and styling. As NCAP has higher and higher requirements for safety stars, pedestrian protection is becoming more and more important. Head injuries are a key cause of serious injury and death in pedestrian injury accidents. [0003] Tests of head module impact bonnets have shown that increased free space under the bonnet reduces the head injury value (HIC). The active hinge used for the vehicle's bonnet is firstly configured to open the bonnet in case of service and, secondly, to allow adjustment of the bonnet height in the event of a pedestrian collision. At present, most active pedestrian p...
