Specific embodiment
In order to be more clear goal of the invention of the invention, technical solution and its advantageous effects, below in conjunction with attached drawing
And specific embodiment, the present invention will be described in further detail；
In the accompanying drawings: a kind of self-priming tail-gate lock, including lock body 1；It is characterized by: being arranged on the panel of the lock body 1
There is U-shaped gap 2, is provided with side plate 3 around panel, it is end to end between adjacent side plate 3；The upper surface of its latus inframedium a3-1 is set
It is set to acclive step surface；The left side of the U-shaped gap 2 is provided with pawl shaft 4, and pawl 5, spine are provided in pawl shaft 4
Detent spring is provided between pawl 5 and panel, the right side of pawl 5 is provided with pawl release arm 6；Pawl transmission arm 7 is connected with pawl 5
It connects, and the end of pawl transmission arm 7 is arranged on the step surface of side plate a3-1；The right side of U-shaped gap 2 is provided with ratchet shaft 8, spine
Ratchet 9 is provided on wheel shaft 8, ratchet 9 is meshed with pawl 5, and lock 10 is provided in the arc groove of ratchet 9；The pawl
The front of axis 4 is provided with worm gear 11, and cam 12 is provided with above worm gear 11, and cam 12 is in contact with pawl transmission arm 7；Described
The front of ratchet shaft 8 is provided with motor 13, and 13 left end of motor is connected with worm screw 14, and worm screw 14 is meshed with worm gear 11；Locking is shaken
The left front of ratchet 9 is arranged in arm 15, and push plate 16 is connected with locking rocker arm 15 and is in contact with ratchet 9；The locking is shaken
Arm 15 is connected with external actuator.
The worm screw 14 is four-head copper worm screw；The worm gear 11 is serration worm gear；The end of the pawl transmission arm 7
End extends to the outside of side plate a3-1；The push plate 16 is fixed on slide-bar 17.
Specific implementation of the invention: realize self-suction function: operator at closing time, gently pushes, and is equivalent to and latches motionless, lock
Body moves upwards, and click is engaged in half locked position, and pawl casing acts at this time, and ratchet switch is failure to actuate, system control
External actuator dragging locking rocker arm 15；Push plate 16 pushes up ratchet 9 on the motion profile of restriction, and ratchet 9 is pushed to arrive
Full lock position.
It realizes pawl release function: when enabling, operating tail-gate opening handle (button), motor 13 drives 14 snail of worm screw
11 movement of wheel, the cam 12 on worm gear 11 push pawl transmission arm 7, and then pushes pawl 5 to disengage and engage with ratchet 9;Pawl
5 under the action of detent spring, can move to 5 ratchet 9 of pawl engagement direction, but pawl transmission arm 7, be discharged at this time by pawl
