In addition, referring to fig. 1 and fig. 3 at the same time, it can be seen that, in the present embodiment, the base 33 of the present invention is further provided with a limit bolt 37. When the vehicle front cover is not collided, the limit bolt 37 can correspondingly abut against the rear connecting rod 34, an operator can change the protruding height of the limit bolt 37 compared with the base 33 by adjusting the limit bolt 37 up and down, and at the moment, the limit bolt 37 can still abut against the rear connecting rod 34 so as to limit the position of the rear connecting rod 34 in the rotating process when the vehicle front cover rotates around the hinge shaft of the vehicle front cover and is normally opened or closed.
FIG. 5 is a schematic diagram of a lifting mechanism pushing a rear link when a front cover of an active front cover system of a vehicle is closed according to an embodiment of the present invention.
As shown in fig. 5 and also seen in fig. 1, in the present embodiment, the lifting mechanism 5 according to the present invention can be connected to the rear connecting rod 34, and the lifting mechanism 5 may include: a gas generator 51 and a piston rod 52 connected thereto. Wherein, the piston rod 52 can be connected with the rear connecting rod 34 by a bolt connection.
When the front cover of the conventional automobile is opened and closed, the lifting mechanism 5 does not act, and only the four-bar hinge mechanism 3 is needed to realize the function of a common hinge, namely, the front cover of the automobile is only opened or closed; when the vehicle front cover is collided, the gas generator 51 in the lifting mechanism 5 can be ignited to drive the piston rod 52 to act, and the piston rod 52 can correspondingly push the rear connecting rod 34 to break the hollow pin of the locking element 36, so that the rear connecting rod 34 slides relative to the restraint rod 35 and lifts the vehicle front cover inner plate 2 in the height direction of the vehicle, and further lifts the vehicle front cover.
It should be noted that in certain preferred embodiments, the active vehicle front cover system of the present invention may further include a crash sensor and a vehicle control module in data communication therewith. The vehicle control module may be connected to the lifting mechanism 5, and when the collision sensor detects a collision signal of a collision of the vehicle, the vehicle control module may control the lifting mechanism 5 to perform an action of pushing the rear link 34.
Fig. 6 is a schematic structural view of the four-bar hinge mechanism of the structure shown in fig. 5.
As shown in fig. 6 and also shown in fig. 5, in this embodiment, the active vehicle front cover system according to the present invention may further include: a detent 38 and a bore recess 39. Wherein, the bayonet 38 and the hole groove 39 can be respectively arranged between the rear connecting rod 34 and the restraining rod 35, and the bayonet 38 can be correspondingly arranged in the hole groove 39, and the hole groove 39 can extend along the radial direction of the rear connecting rod 34.
It should be noted that, when the gas generator 51 is ignited and the driving piston rod 52 pushes the rear connecting rod 34 to slide relative to the restraining rod 35, the detent 38 can also slide in the hole 39, and when the detent 38 abuts against one side end of the hole 39, the rear connecting rod 34 can be prevented from further sliding relative to the restraining rod 35, so as to limit the height of the vehicle front cover lifted.
It can be seen that in the present invention, the length of the hole groove 39 can limit the height of the vehicle front cover to be lifted to some extent, so that the operator can control the height of the vehicle front cover to be lifted by controlling the length of the hole groove 39. In some embodiments, in order to ensure that the vehicle front cover is lifted for pedestrian protection, the length of the hole groove 39 may be controlled to be 90mm or more.
Fig. 7 is a schematic structural view of the four-bar hinge mechanism of the structure shown in fig. 1.
As shown in fig. 7 and also referring to fig. 4, in the present embodiment, a stop block 333 may be further disposed in the first sliding groove 331 of the base 33 according to the present invention. The stopper 333 is provided not only in the first slide groove 331 but also behind the second hinge shaft 312 at the lower end of the front link 31.
Accordingly, with further reference to fig. 7, it can be seen that in this embodiment, a U-shaped spring 334 may be further disposed on the base 33 according to the present invention, and the U-shaped spring 334 may be connected to the stopper 333.
It should be noted that, in the present invention, the second hinge shaft 312 can slide along the first sliding slot 331, but in the present embodiment, the stopper 333 and the U-shaped spring 334 are provided, so that the sliding of the second hinge shaft 312 can be limited to some extent by the mutual fit between the two.
In the practical application process, when the front cover of the vehicle is not collided and the front cover of the vehicle is normally opened and closed, the front cover of the vehicle can drive the front cover connecting plate 32 of the four-bar hinge mechanism 3 to move, so as to drive the front connecting rod 31 and the rear connecting rod 34 to correspondingly insert the restraint rod 35 to rotate, the front connecting rod 31 and the restraint rod 35 only rotate with the hinge shaft hinged with the base 33, the front cover connecting plate 32, the front connecting rod 31, the rear connecting rod 34 and the restraint rod 35 move together, and at the moment, the lifting mechanism 5 does not participate in the movement.
When the front cover of the vehicle collides with a pedestrian in a frontal collision, the collision sensor of the vehicle can transmit a detected collision signal to the vehicle control module of the automobile, the vehicle control module can output a signal to trigger the lifting mechanism 5, the gas generator 51 in the lifting mechanism 5 is ignited to drive the piston rod 52 to push the rear link 34 to slide relative to the restraining rod 35, and further push the rear link 34 to break the locking element 36, and the locking state is released, so that the rear link 34 can slide upwards along the track of the hole groove 39, and meanwhile, the rear link 34 can rotate around the fourth hinge shaft 352 of the restraining rod 35 on the base 33.
It should be noted that the rear link 34 slides upwards along the track of the hole 39 during the rotation process, and drives the front cover connecting plate 32 and the front cover of the automobile to lift, and when the front cover connecting plate 32 lifts, the second hinge shaft 312 and the stopper 333 of the front link 31 on the base 33 can be pulled to slide backwards on the first slide slot 331 against the spring force of the U-shaped spring 334, and at this time, the front link 31 can also rotate around the second hinge shaft 312 at the same time.
After the pedestrian collides with the automobile and the active front cover of the automobile acts, the lifting mechanism 5 can be reset by pressing the rear part of the front cover of the automobile, and a spare part is inserted to realize temporary reset, so that the automobile can be ensured to normally travel to a 4S store for replacing the gas generator 51.
In conclusion, the active vehicle front cover system can effectively protect the head of a pedestrian, has the advantages of stable and reliable structure, fewer structural components, convenience in operation, low maintenance cost and wide applicability, can be effectively applied to all vehicles, and has good popularization prospect and application value.
Different from the prior art, the active vehicle front cover system adopts reasonable structural design, realizes two motion postures through a set of four-bar hinge mechanism, has the functions of opening and closing the automobile engine compartment cover, can lift the automobile engine compartment cover to a certain height before the head of a pedestrian collides with the engine compartment cover, and can stably fall back in the collision process of the head of the pedestrian and the engine compartment cover, thereby playing a role in buffering and protecting the head of the pedestrian.
