Description

Technical Field

[0001] The utility model relates to the technical field of automobile door locks, in particular to a reinforcement plate for the left front door lock of an automobile. Background Art

[0002] Car doors provide access for drivers and passengers, isolate them from outside interference, mitigate side impacts to a certain extent, and protect occupants. Usually, in order to ensure the rigidity and strength of the car door lock installation point, a door lock reinforcement plate is welded on the door inner panel. The reinforcement plate serves to install the door lock and increase the strength of the door. Currently, the traditional door lock reinforcement plate is an ordinary L-shaped bending structure.

[0003] The Chinese patent publication number is CN205936022U, and the authorization announcement date is February 8, 2017. It discloses a vehicle door lock reinforcement plate having a lock hole formed therein and a groove formed above the lock hole. The groove is filled with a sealing material for sealing against the inner door panel of the vehicle. This arrangement eliminates the gap between the inner door panel above the vehicle door lock and the vehicle door lock reinforcement plate, thereby preventing water from flowing through the gap between the inner door panel and the door lock reinforcement plate and into the vehicle door lock, effectively preventing corrosion of the vehicle door lock. Furthermore, it can delay the degradation of the vehicle door lock's performance, extend the service life of the vehicle door lock, and improve the quality and reliability of the vehicle door lock. The utility model also provides a vehicle equipped with such a vehicle door lock reinforcement plate.

[0004] The existing door lock reinforcement plate is connected to the vehicle body by welding. During installation, the worker needs to hold the door lock with one hand and perform the installation work with the other hand. The operation is time-consuming and labor-intensive. Welding cannot absolutely fix the door and lacks a lateral limit function. When the vehicle door collides from the side, the door lock reinforcement plate is easily cracked and knocked open, which reduces the installation effect of the door lock reinforcement plate and cannot meet the use requirements.
