The automotive oil tank door lock has the advantages of ensuring the accurate alignment between the bolt and a lock hole in the lock hole seat and avoiding the phenomenon that the oil tank door is difficult to lock or cannot be locked.

Description

technical field [0001] The invention relates to an automobile closure, in particular to an automobile fuel tank door lock. Background technique [0002] The fuel tank door lock is an important mechanism to realize the opening and closing of the fuel tank door. The force acting on the fuel tank door lock is transmitted to the lock tongue through the cable, so that the lock tongue retracts from the lock hole of the lock hole seat, and the fuel tank door pops open. Unlock to realize the fuel tank door opening process. Release the force of the cable, and the dead bolt resumes the extended state. When the external force pushes the fuel tank door to close, the fuel tank door hits the lock tongue to retract the lock tongue. When the fuel tank door continues to move forward until the lock hole of the lock hole seat is aligned with the lock tongue, the lock tongue extends into the lock hole and locks, realizing the fuel tank door. Close the process. [0003] Existing fuel tank doo...

AI Technical Summary

Problems solved by technology

[0003] Existing fuel tank door lock comprises the key hole seat that is located on the fuel tank door, is located at the lock body on the vehicle body, is located at the dead bolt in the lock body, return spring and spring seat, the drag cable that is connected with dead bolt; Therefore, when the fuel tank door is closed, the lock hole and the lock tongue are not easy to align. In addition, when there are manufacturing errors or the fuel tank door falls down, it is easy to find that the fuel tank door is difficult to lock or even impossible to lock. Therefore, it is necessary to make improvements
