Description

Two, vehicle lock

Technical field

The utility model relates to two, a kind of vehicle lock.

Background technology

Traditional automobile backrest lock only has single unlatching and latch functions; If run into some extreme cases, as road bump, when people's spirit is tired, during long-time sitting, back of seat can be adjusted a more comfortable position backrest rest.

Utility model content

In view of the deficiency that background technology exists, technical problem to be solved in the utility model is to provide a kind ofly has two two gear latch functions and more efficient, firm two, the vehicle lock of drive mechanism.

The utility model takes following technical scheme: two, vehicle lock, comprise housing and locking bar, be provided with lock leaf in housing and open rocking arm, lock leaf has two grades of lock grooves, corresponding two grades of lock grooves are configured with double lock bar, described housing comprises upper shell and lower house, described lock leaf adopts the first pivot to be connected between upper shell and lower house, described unlatching rocking arm adopts the second pivot to be connected between upper shell and lower house, described second pivot is wound with torsion spring, torsion spring impels lock leaf towards the power in sealed direction to opening rocking arm applying, described upper shell offers arc guide groove, described lock leaf adopts the 3rd pivot pivot joint with unlatching rocking arm, 3rd pivot enters in the arc guide groove on upper shell.

In the utility model, lock leaf in case product adopts pin-jointed structure with unlatching rocking arm, make torsion spring can apply counter-force to unlatching rocking arm, open rocking arm and adopt the 3rd pivot pivot joint with lock leaf again, 3rd pivot enters in the arc guide groove of upper shell, the counter-force of unlatching rocking arm can be delivered on lock leaf, impel lock leaf to be applied in counter-force to sealed direction all the time.In above-mentioned drive mechanism, the main pin-jointed structure that adopts connects, and coordinate the position of firm 3rd pivot of guide groove, thus make drive mechanism more stable, efficient, and lock leaf has two grades of lock grooves, thus be provided with two grades of latch functions, make seat back carry out appropriateness adjustment, enable personnel wherein more comfortable.
