Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile tailgate technology, specifically to an automobile tailgate structure. Background Technology
[0002] The tailgate is an important component of a car's body structure. It effectively isolates external noise, providing passengers with a quieter and more comfortable riding environment. As part of the vehicle body, the tailgate also protects occupants from external impacts and injuries, and cushions external loads such as pressure from people, vibrations during driving, and stones thrown from the road, thus improving passenger safety and comfort. Car tailgates are typically made of lightweight, high-strength materials such as metal or carbon fiber composites to reduce vehicle weight and improve impact resistance. They are usually equipped with a locking mechanism, including a lock cylinder, lock blocks, and linkage rods, to achieve the locking and unlocking functions of the tailgate.
[0003] Traditional car tailgate structures primarily provide access to the trunk, allowing drivers and passengers to easily retrieve and store items. However, the trunk's internal space is limited, and the amount of items that can be stored is also limited. When closed, the tailgate occupies some trunk space, reducing its capacity and the amount of items that can be stored. To address this issue, some car tailgate designs incorporate recesses on the tailgate surface, allowing items to be placed inside, thus increasing storage capacity. However, this method lacks any restraint or locking mechanism for the items placed in the recesses, limiting its applicability to side-opening tailgates. Since most car tailgates are typically lift-up, this not only compromises storage stability but also degrades the user experience. Therefore, a new car tailgate structure is proposed.
