Specific embodiment
Referring to Fig.1~Fig. 4, the present invention are a kind of opening structure of rear door lock, and locking is engaged including ratchet 1, with ratchet 1
Pawl 2, and the self-priming push rod 4 being engaged with ratchet 1, ratchet 1 are equipped with the hook that stretches out upwards, self-priming push rod 4 with
One rotating device is connected, and the downside of self-priming push rod 4 is equipped with the protruding part being in contact with hook, the bottom of pawl 2 and a pawl
The bottom end of push plate 3 is flexibly connected, and the top of pawl 2 is bent to the direction of 3 place plane of pawl push plate to be extended, in pawl push plate 3
Be provided with impeller 5, the back side of self-priming push rod 4 is equipped with protrusion, raised thickness be greater than between impeller 5 and self-priming push rod 4 away from
From.
The opening structure of this rear door lock, the bottom of pawl 2 are flexibly connected with the bottom end of a pawl push plate 3, the top of pawl 2
It is bent and extends to the direction of pawl push plate 3, pawl push plate 3 is equipped with impeller 5, and impeller 5 is stuck in 4 back side of self-priming push rod protrusion
Lower section, stir impeller 5 during self-priming, impeller 5 pushes self-priming push rod 4 open, so that contact of the protruding part with hook is de-
From adhesive action terminates；After stirring impeller 5 again, pawl push plate 3 is with 2 top curved location contacts of pawl and with 2 turns of pawl
It is dynamic, make the bond-off of pawl 2 Yu ratchet 1, ratchet 1 automatically resets, so that automobile tail gate is the case where rear door lock breaks down
Under be able to achieve normally-open, convenient and reliable operation.
As a preferred embodiment of the present invention, protrusion is a strip flange 41, the bottom edge shape of strip flange 41
For wedge shape, meanwhile, the head of the strip flange 41 is located at the middle part at 4 back side of self-priming push rod, and tail portion is located at 4 back side of self-priming push rod
Tail end, bottom edge from head to tail portion be in Rising Wedge.Further, this strip flange 41 is located at the back side of self-priming push rod 4
Top.The convex design strip flange 41 wedge shaped at bottom edge is stirred into impeller 5, impeller 5 when contacting lock state
It is moved along strip flange 41 from tail portion to head at the back side of self-priming push rod 4, since bottom edge is in rise wedge from head to tail portion
Shape so that close to head side flange height be greater than by caudad side flange height, therefore impeller 5 can more effectively by
Self-priming push rod 4 boosts, so that contact of the protruding part with hook be made to disengage；Meanwhile the self-priming push rod 4 after being open avoids completely
The return space of ratchet 1, ensure that being normally carried out for rear door lock breakdown action.
As a preferred embodiment of the present invention, impeller 5 is a push plate riveting axis, and push plate riveting axle position is in pawl push plate 3
Middle position, the bottom end of push plate riveting axis passes through pawl push plate 3 and the back face of self-priming push rod 4 touches.
As a preferred embodiment of the present invention, protruding part is to hook plate, and the recessed position of plate and hook is hooked when being locked
It fits, drives ratchet 1 to rotate when self-priming push rod 4 rotates, and then ratchet 1 and pawl 2 is made to carry out engagement locking.Hooking plate will link up with
It catches on, the contact of the two is not easy to disengage, it is ensured that lock out action is normally carried out, and locking effect is more preferably.
As a preferred embodiment of the present invention, ratchet 1 has at least two hook tooths, pawl 2 close to the side of pawl 2
It is equipped with the pawl jaw portion with ratchet indented joint.
As a preferred embodiment of the present invention, rotating device is a gear set, and the head of self-priming push rod 4 is connected to gear
The side of driving gear 7 in group.Further, self-priming push rod connecting plate 8 is provided between driving gear 7 and self-priming push rod 4,
Self-priming push rod connecting plate 8 is coaxial fixed with driving gear 7 by a connecting shaft 9, and the head of self-priming push rod 4 is fixed on self-priming push rod
On connecting plate 8.
As a preferred embodiment of the present invention, pawl 2 is connected with pawl push plate 3 by pawl shaft 6.
As a preferred embodiment of the present invention, emergency driving lever, emergency driving lever and pawl push plate are installed in pawl push plate 3
3 are hinged.
During self-priming, the rotation of driving gear 7 drives self-priming push rod connecting plate 8 to rotate, and self-priming push rod 4 is with self-priming push rod
Connecting plate 8 is rotated, and run-off the straight makes it hook the hook that plate catches on 1 top of ratchet when self-priming push rod 4 rotates, to drive spine
Wheel 1 is rotated towards full lock direction, and when half lock position, the hook tooth above 1 side of ratchet is engaged with pawl jaw portion, is continued to rotate
When hook tooth to lower section is engaged with pawl jaw portion, that is, realize full lock.
Any time of self-priming process stirs the push plate riveting axis in pawl push plate 3, pushes self-priming push rod 4 and ratchet 1 open, make
It hooks plate and contacts disengagement with the fitting of hook, lose promotion fulcrum, adhesive action can be stopped；Again since push plate riveting axis is fixed on spine
In pawl push plate 3, pawl push plate 3 is rotated therewith when stirring push plate riveting axis, so that the top curved of pawl push plate 3 and pawl 2
Part contacts and pawl 2 is pushed to rotate to the direction far from ratchet 1, to make the bond-off of hook tooth Yu pawl jaw portion, spine
Wheel 1 can automatically reset after losing motive force, and rear door lock is normally opened.
Using the opening structure, after completing the simultaneously reset of ratchet 1 without waiting for adhesive action, it can just unlock open the door and move
Make, and whether pawl push plate 3 does not impact in normal switch of the initial position to rear door lock, it also can proper solution under emergency condition
Lock opens the door, the damage of automobile tail gate caused by avoiding because of picking lock.
Certainly, design of the invention creation is not limited to above embodiment, and those skilled in the art are not
Equivalent deformation or replacement can be also made under the premise of violating spirit of that invention, these equivalent variation or replacement are all contained in this Shen
It please be in claim limited range.
