Description

Technical Field

[0001] The utility model belongs to the technical field of automobile component design, and in particular relates to a hinge and a vehicle. Background Art

[0002] The front hood of a vehicle is usually connected to the vehicle body by a hinge. Currently, the most commonly used front hood hinge on vehicles is a four-link hinge. The front hood hinge has good rigidity, but the increased rigidity of the hinge will be detrimental to the pedestrian protection of the vehicle and may increase the damage to pedestrians during a collision. For this reason, some existing four-link hinge structures generally improve pedestrian protection by designing a collapse structure on the four-link hinge body and utilizing the collapse deformation of the collapse structure during a collision. However, the existing four-link hinge with pedestrian protection is basically irreparable after being damaged and needs to be disassembled and replaced as a whole, which has high maintenance costs and poor economic efficiency.

[0003] Therefore, there is an urgent need to provide a new hinge and vehicle with pedestrian protection, hoping to solve the technical problem of high maintenance cost after the front cover hinge is damaged in the prior art. Utility Model Content

[0004] In view of this, an object of the present utility model is to provide a hinge and a vehicle, wherein the hinge is suitable for installation on a front hood of a vehicle, thereby facilitating pedestrian protection and reducing maintenance costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hinge, comprising a hinge seat, a hinge arm, and a hinge front link and a hinge rear link whose two ends are respectively hinged to the hinge seat and the hinge arm; it also includes a limiter detachably connected to the hinge front link or the hinge rear link, or the hinge arm, and the hinge seat is provided with a blocking portion for blocking the downward movement of the limiter, and the limiter is provided with a collapse portion.

[0006] In this embodiment, a limiting rod with an adjustable axial position is provided on the limiting member, and the limiting rod can abut against the blocking portion to complete the limiting.

[0007] In this embodiment, a vibration-damping rubber sleeve is fixed to the lower end of the limiter.

[0008] Furthermore, the collapse portion includes two groups of collapse grooves formed on both sides of the limiting member in the longitudinal direction and arranged symmetrically, and the longitudinal direction is the length direction of the hinge arm.

[0009] Furthermore, the blocking portion is a flange portion integrally formed on the hinge seat.

[0010] Furthermore, the limiting member is provided with a positioning flange for mounting and positioning with the hinge front link or the hinge rear link, or the hinge arm.

[0011] Furthermore, an upper limit portion for limiting the upward rotation of the hinge front link and / or the hinge rear link is integrally formed on the hinge seat.

[0012] Furthermore, a bending portion is formed on the hinge arm, and a mounting hole I is provided on the bending portion.

[0013] Furthermore, the hinge front link and hinge rear link are respectively provided with reinforcing ribs arranged conformally along their extension direction.

[0014] The utility model also provides a vehicle, comprising: a vehicle body, a front cover and the hinge described above, wherein the hinge seat is fixedly connected to the vehicle body, and the hinge arm is fixedly connected to the front cover.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention, and the following embodiments and the features in the embodiments can be combined with each other without conflict.

[0022] See also Figure 1-2 , this embodiment discloses a hinge, including a hinge seat 1, a hinge arm 2, and a hinge front link 3 and a hinge rear link 4 whose two ends are respectively hinged to the hinge seat 1 and the hinge arm 2. Specifically, the two ends of the hinge front link 3 are respectively hinged to the hinge seat 1 and the hinge arm 2 through rivets, and the two ends of the hinge rear link 4 are respectively hinged to the hinge seat 1 and the hinge arm 2 through rivets. The hinge front link 3 and the hinge rear link 4 can be columnar, plate-shaped, etc. Here, the hinge front link 3 and the hinge rear link 4 are preferably plate-shaped, and the hinge seat 1 and the hinge arm 2 are also preferably plate-shaped;

[0023] The hinge also includes a stopper 5 detachably connected to the hinge front link 3 or the hinge rear link 4, or the hinge arm 2. The hinge seat 1 is provided with a blocking portion 101 for blocking the downward movement of the stopper 5. The stopper 5 is provided with a collapse portion 501. Specifically, the stopper 5 is preferably a stopper plate. The stopper 5 is preferably detachably installed by screws. The collapse portion 501 may be a collapse groove, a weakened hole or the like.

Figure 1 The middle stopper 5 is detachably mounted on the hinge rear link 4, and the blocking portion 101 is correspondingly arranged at the rear of the hinge seat 1;

[0024] In the above structural design, a collapse portion 501 is designed on a separately arranged limit member 5. When a collision occurs, deformation failure occurs first at the collapse portion 501, usually plastic deformation failure. The limit member 5 no longer forms a limiting effect, and the hinge link and the hinge arm can continue to move downward, which is beneficial to improving the pedestrian protection effect. Moreover, since the limit member 5 is detachably connected, after damage, it only needs to be replaced to be used again, which is beneficial to reducing maintenance costs and reducing damage to the hinge body.

[0025] In this embodiment, a limiting rod 7 with adjustable axial position is provided on the limiting member 5, where "axial" refers to the axial direction of the limiting rod 7 itself, and the limiting rod 7 can abut against the blocking portion 101 to complete the limiting; specifically, the limiting rod 7 here is a limiting bolt, which is threadedly connected to the limiting member 5, and the axial position can be adjusted by rotating the limiting rod 7; in this structural design, the limiting rod 7 provided on the limiting member 5 can be used to adjust the closing position of the hinge arm 2. After being used in the installation of the automobile front hood, the Z-direction position accuracy of the automobile front hood can be adjusted, thereby facilitating the improvement of the matching accuracy between the automobile front hood and the fender, front bumper, etc.; in other embodiments, the limiting rod 7 can also be installed on the blocking portion 101, and the movement of the limiting member 5 is limited by the top end of the limiting rod 7. Here, it is provided on the limiting member 5, which is conducive to simplifying the hinge body structure.

[0026] In this embodiment, a vibration-damping rubber sleeve 6 is fixed to the lower end of the limit rod 7. Specifically, the vibration-damping rubber sleeve 6 is a rubber sleeve, which can be fixed to the limit rod 7 by interference fit or the like. By arranging the vibration-damping rubber sleeve 6 at the lower end of the limit rod 7, it is helpful to reduce abnormal noise during the opening and closing process of the hinge arm 2. After being used in a car, it is helpful to improve the NVH performance of the car. At the same time, it is also helpful to reduce the wear of the limit rod 7. The vibration-damping energy absorption of the vibration-damping rubber sleeve 6 is also helpful to improve the service life of the hinge as a whole. In other embodiments, the vibration-damping rubber sleeve 6 can also be a vibration-damping rubber pad, which can be fixed on the blocking part 101.

[0027] In this embodiment, the collapse portion 501 includes two groups of collapse grooves 501a formed on both sides of the longitudinal direction of the limit member 5 and arranged symmetrically. Specifically, the collapse grooves 501a here are arc-shaped notches, and the longitudinal direction is the length direction of the hinge arm 2; the collapse grooves 501a have a simple structure and a reasonable arrangement, which is conducive to achieving collapse deformation failure after vertical force.
