The other end of the hinge arm 200 may also be hinged to a trunk lid (not shown) by a hinge pin, but it should be understood that the manner of hinging in the present utility model is not limited thereto, and it may be any form of the prior art as long as the above-described functions can be achieved.

According to an exemplary embodiment of the present utility model, as shown in fig. 2 and 3, the middle portion of the hinge arm 200 is provided with a spring escape groove 220 extending in the length direction at a position corresponding to the spring 520. The length of the spring escape groove 220 should be at least longer than the length of the spring 520 when the trunk lid is fully opened, that is, the length of the spring escape groove 220 should be at least longer than the length to which the spring 520 is stretched, so that the spring 520 can be fully accommodated into the spring escape groove 220, to avoid interference of the spring 520 with the hinge arm 200 to affect the spring 520 to provide an elastic damping force to the hinge arm 200.

According to an exemplary embodiment of the present utility model, as shown in fig. 2 and 3, one end of the spring escape groove 220 is provided with a connection portion 221 for passing through the second connection ring 522 such that the second connection ring 522 is connected to the hinge arm 200 through the connection portion 221.

Fig. 5A to 5C are schematic views illustrating an operation process of the hinge structure of the present utility model when the trunk lid of the vehicle is completely opened from closed. Fig. 5A is a schematic view showing the relative states of the hinge arm 200, the hinge link 400, and the elastic member 500 when the trunk lid of the vehicle is closed. At this time, the hinge arm 200 does not start to rotate, the angle α between the hinge link 400 and the spring 520 is minimum, and the spring 520 is at a natural length. Fig. 5B shows a schematic view of the relative states among the hinge arm 200, the hinge link 400, and the elastic member 500 at an initial stage of the trunk lid opening of the vehicle. At this stage, the hinge arm 200 is accelerated to rotate about the first position 110 in the direction in which the trunk lid is opened by the torque of the torsion bar 300, the angle α between the hinge link 400 and the spring 520 increases, and the spring 520 stretches. When the spring 520 is stretched to a first predetermined length, the elastic force of the spring 520 causes the slide pin 510 to slide along the slide groove 430 from a position near the second end 420 of the hinge link 400 to a position near the first end 410 of the hinge link 400 as the hinge arm 200 continues to rotate. At this time, the elastic force of the spring 520 is mainly used to overcome the frictional force between the sliding pin 510 and the sliding groove 430, and the degree of extension of the spring 520 is small, and the elastic force is small. Fig. 5C shows a schematic view of the relative states among the hinge arm 200, the hinge link 400, and the elastic member 500 at the final stage of the trunk lid opening of the vehicle. At this stage, the hinge arm 200 continues to rotate about the first position 110 in the direction of trunk lid opening under the torque of the torsion bar 300, the angle α between the hinge link 400 and the spring 520 continues to increase, the spring 520 continues to stretch and a resilient damping force is provided to the hinge arm 200. The elastic damping force of the spring 520 serves to slow down the acceleration of the rotation of the hinge arm 200 so that the hinge arm 200 tends to be in a state of uniform rotation from the state of the acceleration rotation, thereby causing the trunk lid of the vehicle to be in a state of uniform opening at the final stage of opening. After the spring 520 is stretched to a second predetermined length, the hinge arm 200 is substantially in a state of being rotated at a constant speed by the elastic damping force of the spring 520, so that the trunk lid of the vehicle is substantially in a state of being opened at a constant speed. Until the trunk lid is fully opened, the angle α between the hinge link 400 and the spring 520 is maximized, and the spring 520 is stretched to the longest.

The operation of the hinge structure for a trunk lid of a vehicle of the present utility model will be described with reference to the accompanying drawings.

When the trunk lid is closed, as shown in fig. 5A, the hinge arm 200 does not start to rotate, the angle α between the hinge link 400 and the spring 520 is minimum, and the spring 520 is at a natural length.

In an initial stage of opening the trunk lid, as shown in fig. 5B, the hinge arm 200 is accelerated to rotate about the first position 110 in the direction of opening the trunk lid by the torque of the torsion bar 300, the angle α between the hinge link 400 and the spring 520 increases, and the spring 520 stretches. When the spring 520 is stretched to a first predetermined length, the elastic force of the spring 520 causes the slide pin 510 to slide along the slide groove 430 from a position near the second end 420 of the hinge link 400 to a position near the first end 410 of the hinge link 400 as the hinge arm 200 continues to rotate.

At the final stage of opening the trunk lid, as shown in fig. 5C, the hinge arm 200 continues to rotate about the first position 110 in the direction of opening the trunk lid, the angle α between the hinge link 400 and the spring 520 continues to increase, the spring 520 continues to stretch and an elastic damping force is provided to the hinge arm 200. The elastic damping force of the spring 520 serves to slow down the acceleration of the rotation of the hinge arm 200 so that the hinge arm 200 tends to be in a state of uniform rotation from the state of the acceleration rotation, thereby causing the trunk lid of the vehicle to be in a state of uniform opening at the final stage of opening. After the spring 520 is stretched to a second predetermined length, the hinge arm 200 is substantially in a state of being rotated at a constant speed by the elastic damping force of the spring 520, thereby causing the trunk lid of the vehicle to be substantially in a state of being opened at a constant speed. Therefore, the trunk lid is stably opened, and the experience of opening the trunk lid by a user is ensured.

The hinge structure for a trunk lid of a vehicle of the present utility model provides an elastic damping force through the elastic member 500 at the final stage of opening the trunk lid, thereby realizing smooth opening of the trunk lid and guaranteeing the use experience of a user. Meanwhile, the hinge structure for the trunk cover of the vehicle has the characteristics of simple structure, lower cost and higher suitability, and is more beneficial to mass production of the vehicle.
