Door lock system for heavy vehicle

Abstract

The invention discloses a door lock system for a heavy vehicle. The door lock system for the heavy vehicle comprises a lock body assembly, an internal opening module, an external opening module, a manual key opening module and a remotely-controlled key opening module, wherein the lock body assembly is of a totally-closed structure, and the parts are encapsulated in a plastic shell, and installed on vehicle door sheet metal in a vehicle door through screws; the internal opening module comprises an internal opening handle assembly, an internal opening handle fixed support and an internal openingpull line; the external opening module comprises an external handle assembly, an external opening change-over crank assembly and an external opening pull rod; the manual key opening module comprisesa lock cylinder assembly and a lock cylinder pull rod; and the lock body assembly is provided with an electric wire bundle used for being connected with a vehicle door control system, so that the operation of remotely controlling a key to open and close the vehicle door. According to the door lock system for the heavy vehicle, the reliability and accuracy of internal opening rotation are ensured,and high waterproof and dustproof characteristics are achieved; an internal opening handle and a change-over mechanism are designed with torsion springs and have a self-return function separately; andthe door lock system for the heavy vehicle is convenient to install, so that the convenience of driving is improved.

Description

technical field [0001] The invention relates to a technical scheme of a truck door lock system, which belongs to the technical field of trucks. Background technique [0002] At present, the field of domestic heavy-duty vehicles is becoming more and more intelligent and automated. Its door lock system is a key system for drivers to enter and exit the vehicle, and its intelligence and durability are of great significance to the comfort of the vehicle. Most of the door lock system lock body assemblies used by domestic trucks are composed of exposed parts, which have poor performance in dustproof and waterproof functions, and most of them still use mechanical locking mechanisms, which cannot be matched with remote keys, and are relatively convenient to use. Difference. And the return of its each opening mechanism all relies on the spring force reset inside the lock body, and this mechanism has reduced the durability of lock body, has defect.

AI Technical Summary

Problems solved by technology

Most of the door lock system lock body assemblies used by domestic trucks are composed of exposed parts, which have poor performance in dustproof and waterproof functions, and most of them still use mechanical locking mechanisms, which cannot be matched with remote keys, and are relatively convenient to use. Difference

And the return of its various opening mechanisms all rely on the spring force inside the lock body to reset. This mechanism reduces the durability of the lock body and has defects.
