The utility model provides a hinge 10, including second linking arm 12, stopper 111, locating part 13, articulated shaft 1302, reset 14, first linking arm 11, second rotor arm 17, hinge seat 15 and first rotor arm 16. The second connecting arm 12 can be connected with the front hatch cover, and after the active front hatch cover function is triggered, the second connecting arm 12 rotates relative to the first connecting arm 11, so that the rear part of the front hatch cover is lifted. The stopper 111 is riveted on the first connecting arm 11 and moves along with the first connecting arm, and the stopper 111 rotates downward relative to the stopper groove 1201 of the second connecting arm 12. The limiting part 13 is connected with the first connecting arm 11, and after the active front hatch cover function is triggered, the locking second connecting arm 12 is kept in a state after jacking. The hinge shaft 1302 fixes the reset element 14 and the limiting element 13 to the first connecting arm 11, and the first connecting arm 11 is provided with a riveting hole. Reset 14 one end and connect in the trompil of first connecting arm 11, one end is connected in the recess of locating part 13, resets 14 and assembles on them two, and at the jacking in-process, locating part 13 drives and resets 14 and rotates together, and this in-process resets 14 and gathers elasticity, ensures that jacking back locating part 13 gets back to initial position. The first connecting arm 11 is arranged on the inner side of the second connecting arm 12 and connected with the second connecting arm 12, the first connecting arm 11 is connected with the second connecting arm 12, and the first connecting arm 11 moves around the hinge seat 15 plate to realize the opening function of the front hatch cover. The second rotating arm 17 and the first rotating arm 16 are both riveted at one end to the first connecting arm 11 and at the other end to the hinge base 15, so that the front hatch cover can be opened and closed according to the related track. The first limiting portion 121 designed on the second connecting arm 12 is matched with the second limiting portion 131 on the limiting member 13, so that the jacking limiting effect is achieved, the upper surface of the first limiting portion 121 is an upward convex arc surface, and the lower surface of the second limiting portion 131 is a downward convex arc surface, so that the smooth movement of the jacking process can be guaranteed. The movement track of the second connecting arm 12 in the bouncing process needs to be considered in the position of the riveting hole of the hinge shaft 1302 on the first connecting arm 11, so that the second connecting arm 12 can freely move to a height which can be separated from the limiting part 13, and the normal limiting function is ensured.

The shape design of the limiting part 13 needs to be combined with the motion track of the second connecting arm 12, so that the situation that the two parts interfere in the motion process to cause the motion jamming is avoided, and the front hatch cover cannot be bounced within the required height range to influence the pedestrian protection performance.

The hinge shaft 1302 is connected with the first connecting arm 11 in a riveting manner, but after the connection, the pressure between the limiting member 13 and the limiting spring and between the limiting member 13 and the first connecting arm 11 is ensured to be small enough, so that the limiting member 13 can smoothly rotate and reset in the bouncing process of the second connecting arm 12, and a bushing part can be added as necessary to meet the motion requirement of the limiting member 13.

The reset member 14 can be made of stainless steel, and as shown in fig. 1, the reset member is in an assembled shape, but not in a free state, and the free state shape ensures that the torsion spring maintains a certain elastic force after being assembled, so as to ensure that the limiting member 13 can be firmly stabilized in an initial state.

The stop member 112 of the first connecting arm 11 can be manufactured by stamping, riveting, or welding, and the stop member 112 of the first connecting arm 11 and the reset member 14 cooperate with each other to determine the initial position of the limit member 13. The position and size of the boss need to consider the external dimension and motion trajectory of the limiting piece 13, so that the limiting piece 13 can freely move and accurately limit in the jacking process.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description is made in conjunction with the accompanying drawings 1 to 5 to explain the working principle of the present invention in detail. This will assist those skilled in the art in further understanding the present invention.

After receiving a starting command sent by the ECU, the active front hatch cover system can instantly explode the active front hatch cover jacking device, the explosion energy accumulated in the jacking device acts on a mandril in the jacking device to push the second connecting arm 12, and a buffer part 122 (such as a riveting pin) between the first connecting arm 11 and the second connecting arm 12 is cut off, so that the first connecting arm 11 and the second connecting arm 12 are separated and can relatively move; then, the first connecting arm 11 starts to rotate upward around the first rotating arm 16 and the second rotating arm 17, and at the same time, the second connecting arm 12 starts to rotate upward around the front end of the hinge 10 relative to the first connecting arm 11, and as the second connecting arm continues to rotate, when the first surface of the first position-limiting portion 121 contacts the second surface of the first position-limiting portion 121, the position-limiting member 13 is pushed to rotate around the hinge shaft 1302, and then the rotation of the position-limiting member 13 drives the reset member 14 to rotate and deform, and the reset member 14 generates a resettable elastic force during the rotation process, as shown in fig. 2; when the first position-limiting portion 121 of the second connecting arm 12 moves to the moment of being separated from the second position-limiting portion 131 of the position-limiting member 13, the position-limiting member 13 rotates back under the action of the elastic force stored in the rotating deformation process of the restoring member 14, and returns to the initial state, as shown in fig. 3; when the second connecting arm 12 continues to rotate upwards and is blocked by the limiting block 111 to fall back, the reset limiting block 13 rotates to lock the limiting structure, the upper surface of the limiting structure clamps the lower surface of the first limiting part 121, and the two surfaces contacting the limiting structure are designed to be flat surfaces, so that the purpose of locking the second connecting arm 12 is achieved, the second connecting arm cannot continue to fall back, and finally the front hatch cover is kept in a bouncing state, as shown in fig. 1; just so can increase the distance between preceding cabin cover and the inside hard spot of preceding cabin cover, provide sufficient cushion time for pedestrian's head to promote pedestrian's protection performance, mainly be the protection of pedestrian's head.

The limiting member 13 can be designed into different shapes according to the arrangement space and the movement track of the first limiting portion 121 on the second connecting arm 12, and can be designed into a limiting bracket even under the limitation of space and arrangement, and the purpose of locking and limiting can be achieved as well, as shown in fig. 5, another form of the limiting member 13 is provided. In addition, the limit member 13, the hinge shaft 1302 and the reset member 14 may be mounted on the second connecting arm 12 in an inverted manner, and then the first limit portion 121 may be added to the first connecting arm 11.
