Description

Snow load structure of tail gate electric suction lock

Technical Field

The invention relates to the technical field of vehicle door locks, in particular to a snow load structure of a tail gate electric suction lock.

Background

The door lock generally has the function of no snow load (the snow load function means that a passenger can open the door lock through a cockpit key or remote control or manual operation but before the door is not completely separated from the lock hook, the door can be opened at any time after waiting for any time, and the door can not be closed again before the door is not completely separated from the lock hook (half lock of the door lock)), or the snow load function in the market is failed after half lock. Therefore, the passengers get articles after getting off are very inconvenient, because the passengers do not open the car door quickly after opening the door lock through the keys or the remote control key or the corresponding switch, the car door can return to a half-lock state and needs to open the tail door again in a corresponding mode, and the car door can return to a full-lock state to completely close the car door in an electric suction lock state, so that the experience of the passengers is very poor. Therefore, the factory provides a snow load structure of the electric absorbing lock for the tail gate, which can be opened before the door lock is not completely separated from the locking hook.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a snow load structure of a tail gate electric suction lock, which solves the problem that a passenger does not quickly open a gate after opening the gate lock by a key or a remote control key or a corresponding switch, the gate may return to a half-lock state, the tail gate needs to be opened again in a corresponding mode, and the gate may return to a full-lock state to completely close the gate in an electric suction lock state, so that the experience of the passenger is very poor.

In order to realize the purposes that the snow load structure can open the electric suction lock of the tail door before the door lock is not completely separated from the lock hook, and meanwhile, the snow load structure has small volume, convenient use and higher reliability, the invention provides the following technical scheme: the utility model provides a snow of tail-gate electricity suction lock carries structure, includes pawl, ratchet and the rocking arm of unblanking, the front end of pawl is provided with the pawl torsional spring, the one end of ratchet is provided with the transposition conversion arm, the front end of ratchet is provided with the ratchet torsional spring, the one end of transposition conversion arm is provided with the follow-up rocking arm, the rocking arm setting of unblanking is in the one end of pawl torsional spring.

Preferably, the pawl torsion spring is fixedly mounted on a side wall of the mounting column, and the mounting column is fixedly mounted in the inner mounting cylinder of the pawl.

Preferably, the pawl torsion spring support acts against the side wall of the ratchet wheel.

Preferably, the inside of the torsion conversion arm is arranged at the front end of the ratchet wheel through an installation part, and a transposition torsion spring is fixedly arranged on the side wall of a front end convex ring of the torsion conversion arm.

Preferably, the ratchet torsion spring is arranged on the side wall of the connecting piece, and the connecting piece is fixedly connected in a groove in the middle of the ratchet.

Preferably, an end of the unlocking rocker arm acts on the column and is supported at one end of the pawl.
