Door lock of double-side-door vehicle and locking mechanism of door lock

Abstract

The invention relates to a door lock of a double-side-door vehicle and a locking mechanism of the door lock. The locking mechanism comprises an elastic press piece, an unlocking pull piece, a disengaging and engaging part and a connecting piece. The unlocking pull piece can unlock a lock body of the door lock, and the lock body is used for locking a rear door of the vehicle. The disengaging and engaging part comprises a rotating piece, and the rotating piece can rotate under the driving of an inner handle and pull the unlocking pull piece to unlock the lock body. The connecting piece is connected between the elastic press piece and the rotating piece. The elastic press piece is arranged on a rear door metal plate or a door frame metal plate of the vehicle, the elastic press piece can be pressed when a front door of the vehicle is closed, when the elastic press piece is in a pressed state, the elastic press piece can act on the rotating piece through the connecting piece to enable the rotating piece to be separated from the inner handle, and when the elastic press piece is in a pop-up state, the elastic press piece can act on the rotating piece through the connecting piece to enable the rotating piece to be matched with the inner handle. The locking mechanism can ensure that passengers in the vehicle cannot open the rear door by rotating the inner handle when the front door of the double-side-door vehicle is in a closed state, so that the safety is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a door lock and a locking mechanism for a side-by-side vehicle. Background technique [0002] The main feature of the side-by-side model is that the front and rear doors are in the form of two-fold, and the rear door opening is large when fully opened, which improves the entry and exit experience of the rear passengers. The mechanism (lock catch) can only be arranged on the rear door, and the rear door is used as a B-pillar to ensure that the front door is locked after being locked; therefore, the door closing sequence of the side-to-door model is: first close the rear door, then close the front door; the door opening sequence is: open the front door first , Open the back door again. [0003] In order to ensure the above door opening sequence, the rear door must have a reliable locking mechanism to ensure that the rear door cannot be unlocked first when the front door is n...

Problems solved by technology

[0003] In order to ensure the above door opening sequence, the rear door must have a reliable locking mechanism to ensure that the rear door cannot be unlocked first when the front door is normally closed, otherwise the rear door is not locked, and the front door will also be in an active state. Hidden danger: Usually, there are two types of locking devices for independent doors: electronic and mechanical, both of which can be operated manually. However, on side-by-side models, this type of locking may not be applicable due to the above-mentioned connection between the front door and the rear door. And the current door is closed. To ensure safety, passengers in the car are prohibited from unlocking the rear door by turning the inner handle.
