That is, when the vehicle collides with a pedestrian, the jack 1 receives a sensor signal to explode and bounce, and the jack 11 is protruded upward in the vehicle height direction.
Further, the hinge lifting mechanism 2 is connected between the vehicle body 300 and the rear end of the hood 200 so that the hood 200 can rotate relative to the vehicle body 300 to satisfy normal opening of the hood 200 relative to the vehicle body 300, to facilitate maintenance of components in the front cabin, and the like.
In order to better protect the head of a pedestrian when the pedestrian collides with the engine cover 200, the embodiment of the invention enables the hinge lifting mechanism 2 to have a locking state and an unlocking state, namely, under normal conditions, the hinge lifting mechanism 2 is in the locking state so as to meet the rotation relative to the vehicle body 300 when the front end of the engine cover 200 is opened, and when the vehicle collides with the pedestrian, the ejector rod 11 stretches upwards, at this time, the ejector rod 11 can jack up the hinge lifting mechanism 2, then the hinge lifting mechanism 2 can be converted into the unlocking state from the locking state, and the hinge lifting mechanism 2 can lift the rear end of the engine cover 200 so as to form a buffer space 3 between the engine cover 200 and the vehicle body 300. Therefore, when the pedestrian head collides with the engine cover 200, the buffer space 3 can play an effective role in buffering so as to effectively protect the pedestrian head from being damaged by the collision, thereby improving the pedestrian protection performance of the vehicle.
According to the hood hinge assembly 100 of the embodiment of the present invention, the hood hinge assembly 100 is capable of lifting the rear end of the hood 200 when a vehicle collides with a pedestrian to form the buffer space 3 between the rear end of the hood 200 and the vehicle body 300, thereby effectively protecting the head of the pedestrian from the collision.
With reference to the embodiment shown in fig. 1-9, the hinge lifting mechanism 2 comprises: the first hinge arm 21 and the second hinge arm 22 are connected by rivets to realize rotatable connection between the first hinge arm 21 and the second hinge arm 22, wherein the first hinge arm 21 is rotatably arranged relative to the vehicle body 300, and the second hinge arm 22 is fixedly connected with the rear end of the engine cover 200, so that the rear end of the engine cover 200 is movable relative to the vehicle body 300.
Wherein, the ejector rod 11 is adapted to push the first hinge arm 21 to rotate in the lifting direction of the engine cover 200, and after the first hinge arm 21 rotates, the first hinge arm 21 is adapted to drive the second hinge arm 22 and the engine cover 200 to lift up to achieve the unlocking state.
Further, referring to fig. 1, the first hinge arm 21 is longer than the second hinge arm 22, and an end (rear end) of the first hinge arm 21 remote from the front end of the hood 200 is rotatably connected to the vehicle body 300. That is, the first hinge arm 21 may be directly rotatably connected to the vehicle body 300 through a pin, or may be connected to the vehicle body 300 through the vehicle body fixing arm 6, that is, the vehicle body fixing arm 6 is fixed to the vehicle body 300, and the first hinge arm 21 is rotatably connected to the vehicle body fixing arm 6, so that the first hinge arm 21 may be rotated with respect to the vehicle body 300.
Still further, one end of the first hinge arm 21 near the front end of the hood 200 (front end in the vehicle length direction) is rotatably connected to one end of the second hinge arm 22 near the front end of the hood 200 (front end in the vehicle length direction), and the upper wall of the second hinge arm 22 is fixedly connected to the lower wall of the hood 200 (refer to fig. 1). Thus, when the first hinge arm 21 is lifted up, the first hinge arm 21 will jack up the hood 200 to move the hood 200 up, and the movement of the hood 200 will drive the movement of the second hinge arm 22 to limit the lifting distance of the hood 200 and ensure the stability of the lifting process of the hood 200 by the rotatable connection of the first hinge arm 21 and the second hinge arm 22.
And, the overall structure of the hinge lifting mechanism 2 is more stable than conventional active hinge structures employing shear pins or tension pins, and less energy is required from the jack 1, resulting in lower overall cost of the hood hinge assembly 100.
