Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile hinge equipment, and in particular relates to a lightweight hinge. Background Art
[0002] In order to facilitate the placement of larger objects in the trunk, traditional SUV cars usually have a double-door structure, thereby further increasing the entrance to the trunk. However, the traditional connection structure usually requires the use of hinges and hydraulic rods to open and close the trunk. However, the traditional hydraulic rod needs to be installed between the trunk door and the vehicle body, which makes the hydraulic rod easily bumped and broken during loading and unloading of goods, thus affecting the use of the trunk. In addition, traditional hinges are heavy, and the use of a double-door structure will inevitably increase the use of hinges, thereby increasing the weight of the vehicle and affecting the vehicle's fuel consumption.
