Description

Technical Field

[0001] This utility model belongs to the field of automotive trunk technology, and more specifically, relates to a hinge connection structure for automotive trunks. Background Technology

[0002] As an essential opening and closing component of a car, the trunk is a part that users open very frequently during use. This makes the trunk a focus of attention for users. As a result, the gaps and surface differences between the trunk and its surrounding parts are also extremely sensitive. This requires that, while meeting the precision requirements of the trunk itself, when it is assembled into the body-in-white, the cumulative dimensional tolerances of parts other than the trunk should be minimized as much as possible to effectively ensure the quality of the appearance matching of the trunk and its surrounding parts.

[0003] Currently, the industry's approach to luggage assembly involves using hinged flaps to self-position themselves onto the luggage, followed by hinge mounting brackets that are fixed to the vehicle body in the Z-direction. The luggage assembly is then centered in the Y-direction and aligned with the side panels in the X-direction through appearance matching. While this method can achieve appearance matching adjustments in the Y and X directions, the Z-direction, being a tightening direction, can only be adjusted through localized straightening. However, straightening alters the overall posture of the luggage, and since there are gap and surface difference matching requirements around the entire luggage perimeter, this results in adjustments needing to be made around the entire luggage, increasing adjustment time and impacting the luggage's connection strength and durability.

[0004] Existing technology includes a designation titled "Automotive Trunk Lid Hinge Assembly" with publication number CN104863444A. This technology discloses an automotive trunk lid hinge assembly comprising a gooseneck-shaped hinge welded body. The hinge welded body includes a door cover mounting bracket, a bent tube, a buffer block bracket, and a hinge shaft bracket. A tension spring bracket is mounted on the buffer block bracket. The door cover mounting bracket is connected to the vehicle body via a hinge shaft, a hinge shaft bushing, and a retaining ring. The tension spring bracket is connected to the tension spring via a bushing, a hinge shaft retainer, a locking bolt, and a locking nut. The design of this invention's trunk lid hinge satisfies the different requirements of various cars for trunk space structure while also achieving low manufacturing costs.
