Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a door hinge seat. Background Art

[0002] Hinge, also called hinge or door hinge, is a mechanical device used to connect two solid bodies and allow them to rotate relative to each other. Its main feature is to provide a buffering function when the cabinet or door is closed, which minimizes the noise caused by the collision with the body when closing. The door provides a passage for the driver and passengers to enter and exit the vehicle, and isolates the interference outside the vehicle, which can reduce the side impact to a certain extent and protect the occupants. The main function of the door hinge seat is to fix the door and enable it to open and close. It can also bear the weight and impact of the door and maintain the stability and safety of the door.

[0003] At present, in the automobile production process, hinges are needed to assemble the door and the body, but the existing hinges are cumbersome in the assembly process, and the existing hinges are not convenient to adjust the rotation flexibility after installation, and the door hinge seat needs regular maintenance and inspection to ensure its normal operation and extend its service life. After the door hinge is used for a long time, the bolts will become loose, which is inconvenient for replacing the hinge. For this reason, we propose a door hinge seat. Utility Model Content
