The invention relates to the field of vehicles, and discloses an air supporting device, a machine cover hinge mechanism and a vehicle. The air supporting device (10) comprises a cylinder barrel (11) and a supporting rod (12) penetrating through the cylinder barrel, wherein the supporting rod divides the interior of the cylinder barrel into a first cavity with the supporting rod and a second cavity C which is not provided with the supporting rod and is sealed with the supporting rod; the cylinder barrel comprises a bottom wall for limiting the second cavity C; the bottom wall comprises a fixed part and a movable part; the fixed part is provided with a through hole (111); and the movable part is arranged at the through hole and can move relative to the fixed part so as to be switched between an open state for opening the through hole and a closed state for closing the through hole. When an upper plate of a machine cover hinge is bounced, the supporting rod is driven to be quickly away from the bottom wall, so that the pressure of the second cavity is quickly reduced, the movable part moves under the action of external air pressure to open the through hole, and the supporting rod can reach the limit position at the highest speed. When resetting is needed, only the second cavity needs to be exhausted.
Description
technical field [0001] The present application relates to the vehicle field, in particular to an air strut, a hood hinge mechanism and a vehicle. Background technique [0002] With the popularization of vehicles, traffic accidents will inevitably be caused. Pedestrians are usually seriously injured in traffic accidents where pedestrians are struck, and therefore, vehicle designs have undergone numerous improvements to reduce injuries to pedestrians during collisions. For example, use a hood hinge mechanism that can actively pop up in the event of a collision to minimize head injuries to pedestrians in the event of a collision. In the prior art, the hinge mechanism of the hood bounces up in the event of a collision (including erroneous activation in response to an erroneous collision signal), and then restricts the pop-up position through a rigid stopper, and cannot be reset after bouncing up, and the pop-up impact is usually It will damage the hinge mechanism of the mechan...
