Referring to fig. 1 to 5, a novel electric absorption lock for a rear door of an automobile includes:
a base 10;
a lock back plate 20 disposed on the base 10;
a pawl 31 installed in the base 10 by a first torsion spring 41;
a ratchet 32 mounted in the base 10 via a second torsion spring 42 and abutting against the pawl 31;
a ratchet wheel connecting swing arm 50 which is arranged on the base 10 and is connected with the ratchet wheel 32;
a motor 60 having an output end connected to a first gear 71;
the second gear 72 is rotatably arranged on the lock back plate 20 and is meshed with the first gear 71, and an arc-shaped groove 721 and a movable rod 722 movably arranged in the arc-shaped groove 721 are arranged on the second gear 72;
a lock swing arm 80, one end of which is rotatably connected with the lock back plate 20, the other end of which is provided with a movable groove 81, and a movable rod 722 extends into the movable groove 81;
an emergency switch 90 rotatably provided on the lock back plate 20 and abutting against the pawl 31;
the motor 60 can drive the first gear 71 to drive the second gear 72, the movable rod 722 and the lock swing arm 80 to move, so that the other end of the lock swing arm 80 can drive the ratchet connection swing arm 50 and the ratchet 32 to rotate for locking; the emergency switch 90 can push the movable rod 722 and the lock swing arm 80 to move from one end of the arc slot 721 to the other end of the arc slot 721 when being pressed, so that the lock swing arm 80 and the ratchet connection swing arm 50 are separated from abutting connection and the pawl 31 and the ratchet 32 are separated from abutting connection, and the ratchet connection swing arm 50 can drive the ratchet 32 to rotate under the action of the second torsion spring 42 to unlock.
In the utility model, the motor 60 drives the first gear 71 to rotate, the first gear 71 drives the second gear 72 engaged therewith to rotate when rotating, when the emergency switch 90 is not pressed, the movable rod 722 is positioned at one side of the arc-shaped groove 721 close to the ratchet connection swing arm 50, and the movable rod 722 is positioned at the upper end of the movable groove 81, so that when the second gear 72 rotates, the movable rod 722 is driven to move towards the direction of the ratchet connection swing arm 50, and because the movable rod 722 extends into the movable groove 81, the locking swing arm 80 is driven to move, and then the east ratchet connection swing arm 50 moves, and because the ratchet connection swing arm 50 is connected with the ratchet 32, the ratchet 32 is driven to rotate, so that the locking hook part on the ratchet 32 hooks the latch, and locking is completed; the unlocking principle of the emergency switch 90 is as follows: when the emergency switch 90 is pressed, the emergency switch 90 forces the pawl 31 and the ratchet wheel 32 to separate during the action, and the ratchet wheel connecting swing arm 50 and the ratchet wheel 32 are driven by the second torsion spring 42 to reset to unlock.
Because the movable rod 722 of the common electric suction lock is fixedly connected with the second gear 72, the emergency switch 90 can be used for unlocking under the condition that the motor 60 and the second gear 72 are reset, otherwise, the ratchet connecting swing arm 50 is propped by the movable rod 722 on the second gear 72 and cannot be reset, and the ratchet 32 cannot be driven to unlock, so that the emergency switch 90 cannot be used for unlocking; in the utility model, the movable rod 722 and the second gear 72 are in a separated state, and the arc-shaped groove 721 is arranged, so that the emergency switch 90 can drive the movable rod 722 to move from one side of the arc-shaped groove 721 to the other side, therefore, the lock swing arm 80 can be pushed to return to the position of the unlocked state by pressing the emergency switch 90 under the condition that the second gear 72 is not reset, and further, the ratchet wheel connecting swing arm 50 can also return to the position of the unlocked state under the action of the second torsion spring 42 under the condition that the emergency switch 90 pushes and forces the pawl 31 and the ratchet wheel 32 to be separated, thereby completing unlocking; the utility model has the advantages that: no matter whether the motor 60 drives the second gear 72 to complete resetting, manual unlocking can be achieved through the emergency switch 90, and using convenience and safety of the electric suction lock are greatly improved.
The novel electric suction lock for the automobile tail door further comprises a tension spring 91, two ends of the tension spring are respectively connected with the lock back plate 20 and the movable rod 722; the tension spring 91 pulls the movable rod 722, so that the movable rod 722 can smoothly move from one side of the arc-shaped groove 721 to the other side; further, the emergency switch 90 is mounted on the lock back plate 20 through a third torsion spring, and can be automatically reset after the emergency switch 90 is used.
The movable slot 81 is provided as a kidney-shaped hole.
The arc slot 721 is provided as a V-shaped slot.
The second gear 72 is provided as a sector gear; this arrangement can reduce the space of the second gear 72 in the lock, and certainly, because of the sector gear, the number of turns of the motor 60 or the working time needs to be strictly controlled, and the rotation angle of the second gear 72 is prevented from being too large.
It is to be understood that the present invention is not limited to the above-described embodiments, and that equivalent modifications and substitutions may be made by those skilled in the art without departing from the spirit of the present invention, and that such equivalent modifications and substitutions are to be included within the scope of the appended claims.
