Abstract
The utility model discloses an internally locking connecting rod device, provided with gear engagement, of an automobile electric door lock. The internally locking connecting rod device comprises a locking handle, a locking spring, an internally locking connecting rod, a pawl clamp and a pawl, wherein the locking handle is riveted on a lock body by the pawl through rivets, and a slave connecting rod of a control handle of the automobile door lock triggers the locking handle to rotate on the riveted plane; the locking spring is arranged in a lock body slot, one end corner of the locking spring is positioned in a side slot of the internally locking connecting rod, and a wedge part of the locking handle is pressed on the locking spring in the lock body slot; and the internally locking connecting rod is assembled on a lock body post, and is meshed with one end of the pawl clamp through wheel teeth arranged on the internally locking connecting rod. According to the internally locking connecting rod device, the position of the internally locking connecting rod is limited in the overall locking and unlocking processes and the gear engagement of the internally locking connecting rod and the pawl clamp is conducted by utilizing the locking spring, the locking handle and a plurality of other connecting pieces usually adopted by other locking structures are omitted, and the compactness and the reliability of the whole device can also be improved while the movement mechanism is simplified.
Description
Technical field
The utility model relates to a kind of interior locking linkage with the gear engagement of electric door lock for vehicle, belongs to the auto-parts technical field.
Background technology
The locking system of most domestic automobile side door lock all adopts a plurality of locking connecting rods to link to each other with the relieving mechanism that opens the door and fetches release and the locking of finishing door lock at present.This automobile side door lock locking system structure is comparatively complicated, and manufacturing cost is high, and part is more, so fault rate is also high.
The utility model content
The utility model purpose: the utility model provide a kind of simple in structure, reliability is high, save the interior locking linkage with the gear engagement of the electric door lock for vehicle of cost.
Technical scheme: a kind of interior locking linkage with the gear engagement of electric door lock for vehicle comprises the locking handle, locking spring, interior locking connecting rod, ratchet clamp and ratchet; Described locking handle is riveted on by pawl rivet with it the lock, touches the locking handle by the control crank slave connecting rod of automobile door lock and rotates on the riveted joint plane; Described locking spring fitting is in lock body groove, and one end angle is arranged in the side channel of locking connecting rod, and the wedge of locking handle partly presses on the locking spring in lock body groove; Described interior locking connecting rod is assemblied on lock Shenzhu, and by establish thereon the gear teeth and an end of described ratchet clamp be connected with a joggle.
When described locking handle rotates on the riveted joint plane, locking handle wedge partly presses the locking spring and moves down in lock body groove, cause two end angles of locking spring up to be lifted, be located at the locking spring terminal angle in the side channel of interior locking connecting rod, interior locking connecting rod is moved up and down along the sub-axis of lock Shenzhu, when up lift at the end angle of locking spring, interior locking connecting rod is also up mobile under the active force at locking spring terminal angle, open the disengagement of handle and interior locking connecting rod in making, thereby reach the effect of locking door lock; But the gear parts of interior locking connecting rod still is meshed with gear on the ratchet clamp and does not throw off, and reaches the effect of accurate release in the process from the lockup state to the released state.
Beneficial effect: compared with prior art, the interior locking linkage with the gear engagement of electric door lock for vehicle provided by the utility model, simple in structure, compact, saved taking up room of door lock, reliability is high, and the gear engagement by locking connecting rod and ratchet clamp reaches accurately release and locking effect.
Whole locking releasing process utilizes the position limitation of the internal locking connecting rod of locking spring, and the gear of interior locking connecting rod and ratchet clamp engagement, cancel locking handle and other a plurality of connectors that other locking structures adopt usually, when simplifying motion, also improved compactedness and the reliability of whole device.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Shown in Fig. 1-5, the interior locking linkage with the gear engagement of electric door lock for vehicle comprises locking handle 1, locking spring 2, interior locking connecting rod 3, ratchet clamp 4 and ratchet 5; Locking handle 1 is riveted on by pawl rivet with it the lock, touches locking handle 1 by the control crank slave connecting rod of automobile door lock and rotates on the riveted joint plane; Locking spring 2 is installed in the lock body groove, and one end angle is arranged in the side channel of locking connecting rod 3, and the wedge of locking handle 1 partly presses on the locking spring 2 in lock body groove; Interior locking connecting rod 3 is assemblied on lock Shenzhu, and by establish thereon the gear teeth and an end of described ratchet clamp 4 be connected with a joggle.
When locking handle 1 rotates on the riveted joint plane, locking handle 1 wedge partly presses locking spring 2 and moves down in lock body groove, cause two end angles of locking spring 2 up to be lifted, be located at the locking spring 2 end angles in the side channel of interior locking connecting rod 3, interior locking connecting rod 3 is moved up and down along the sub-axis of lock Shenzhu, when up lift at the end angle of locking spring 2, interior locking connecting rod 3 is also up mobile under the active force at locking spring 2 end angles, open handle and 3 disengagements of interior locking connecting rod in making, thereby reach the effect of locking door lock; But the gear parts of interior locking connecting rod 3 still is meshed with gear on the ratchet clamp 4 and does not throw off, and reaches the effect of accurate release in the process from the lockup state to the released state.
Motion and the principle of automobile door lock from the lockup state to the released state is the same.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
