Auxiliary door locking device for vehicle door

Abstract

The present invention proposes an auxiliary door lock device for a car door, which consists of a lower block assembly, a first pull rod, an intermediate shaft assembly, a second pull rod, an upper rear block assembly, a third pull rod and A set of link locking mechanism constituted by the upper front side block assembly realizes the auxiliary locking of the door, and achieves adding three new connection lock points between the door and the side door frame when locking, which is different from the existing The door hinge and ordinary door lock work together to further enhance the locking strength of the door, so that when the cab is subjected to a large impact, it can effectively prevent the deformation of the door, greatly enhance the overall rigidity of the door, and ensure driving safety.

Description

technical field [0001] The invention relates to the technical field of automobile doors, in particular to door lock technology, and more specifically to an auxiliary door lock device for a car door. Background technique [0002] In the prior art, the locking of most vehicles is based on connecting hinges and ordinary door locks. Although it can meet the requirements of ordinary locking, it is difficult for some vehicles to be used under special conditions. To meet the needs of use, for example, under the working conditions such as the car door is often subjected to large shock waves, the ordinary car door lock will frequently open involuntarily, causing damage to the car door and the door lock structure, and there is no guarantee in this case. At the same time, when the door is subjected to a large impact, if the locking strength of the door lock is poor, it will not only lead to the involuntary opening of the door, but also pose a threat to the safety of the occupants in th...

[0002] In the prior art, the locking of most vehicles is based on connecting hinges and ordinary door locks. Although it can meet the requirements of ordinary locking, it is difficult for some vehicles to be used under special conditions. To meet the needs of use, for example, under the working conditions such as the car door is often subjected to large shock waves, the ordinary car door lock will frequently open involuntarily, causing damage to the car door and the door lock structure, and there is no guarantee in this case. At the same time, when the door is subjected to a large impact, if the locking strength of the door lock is poor, it will not only lead to the involuntary opening of the door, but also pose a threat to the safety of the occupants in the cab. The door lock structure commonly used in vehicles in the prior art has defects such as poor locking strength and inability to withstand large impacts, which in turn makes the anti-collision rigidity of the entire car door very limited, which has gradually become a problem that needs to be considered in vehicle design safety
