Description
Technical field
The utility model patent relate to a kind of electric door lock for vehicle in open and two draw back opening device, belong to the auto parts machinery technical field.
Background technology
Open two drawing back in the design of present domestic part automobile type requirement door lock possesses and open function, can accomplish unlocking operation when pulling handle in promptly the passenger draws for the first time, accomplish the action of opening car door when drawing internally-opened handle for the second time.Compare separation in straighten one out and ease out his anxiety locking device, in open two drawing back and open the passenger that is more convenient for and in case of emergency accomplish the car door opening action, compare with singly drawing back to open simultaneously, two drawing back opened and can be prevented effectively that maloperation from opening the situation of car door and taking place.And it is comparatively complicated to open two most structures of opening device of drawing back in existing, and manufacturing cost is high, and fault rate is relatively also high.
The utility model content
The utility model purpose: the utility model provides a kind of simple in structure, opens two opening devices that draw back in the electric door lock for vehicle that reliability is high.
Technical scheme: open in a kind of electric door lock for vehicle and two draw back opening device, open handle, ratchet, locking swing arm, locking connecting rod and locking connector in comprising, on the locking connecting rod rod spring is installed, and rod spring rotates together with the locking connecting rod; All have groove on said ratchet and the locking connecting rod; One end of said locking connecting rod is provided with projection, this projection and the locking shift fork engagement that is located at locking swing arm lower end; One end of said locking connector is provided with projection, and in the groove of this projection embedding locking connecting rod, the other end places in the groove on the ratchet, rotates the locking connecting rod locking connector is slided in the groove of ratchet.
Hold the connecting rod that handle can promote locking swing arm and ratchet simultaneously in when rotating internally-opened handle first; Wherein the locking swing arm makes the rotation of locking connecting rod through the locking shift fork that is located at its end, lower end; Because of the projection that is arranged on locking connector one end embeds in the groove of locking connecting rod,, the rod spring on the locking connecting rod in the groove of ratchet, slides so promoting the locking connector; Opening handle in the connecting rod quilt of ratchet promotes rotation and stops the locking connector in the groove of ratchet, to continue to slide; After opening handle in unclamping, the connecting rod of ratchet is got back to initial position under the effect of lock body spring, and the locking connector continues to slide into unlocked position under the promotion of rod spring simultaneously; When for the second time spurring internally-opened handle, in open the connecting rod that handle promotes ratchet, the connecting rod rotation pusher moving lock of ratchet ends connector, promotes the unlatching that car door is accomplished in the ratchet rotation then.This shows; Said process respectively through the locking shift fork and with projection, ratchet and the locking connecting rod of locking connecting rod one end of its engagement on the structure setting of groove; Realized of the restriction of the connecting rod of ratchet to locking connector position; Cancelled the bridgeware of unblanking that two opening structures adopt usually in the prior art, in simplifying, opened and twoly also improved its reliability when drawing back opening device.
The connecting rod of said ratchet is riveted on the lock bed plate, opens handle promotion connecting rod in the rotation and rotates around the riveting point.
Said locking swing arm and door lock housing are hinged, open the swing arm of handle promotion locking in the rotation and rotate around pin joint.
Groove on the said locking connecting rod is a kidney slot, is convenient to fixedly locking connector.
Beneficial effect: open in the electric door lock for vehicle that the utility model provides and two draw back that opening device is simple in structure, reliability is high.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the rear elevation of Fig. 1;
Fig. 4 is the partial structurtes sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model.
Shown in Fig. 1-4: in open handle 1 and be riveted on the lock bed plate, and be fixedly connected with the car door internally-opened handle; The connecting rod 6 of ratchet 2 is riveted on the lock bed plate, opens handle 1 in the rotation and promotes connecting rod 6 and rotate around the riveting point; Locking swing arm 3 is same to flexibly connect through rivet and door lock housing, opens handle 1 promotion locking swing arm 3 in the rotation and rotates around the riveting point; Have groove on the ratchet 2, have kidney slot on the locking connecting rod 4; One end of locking connecting rod 4 is provided with the rectangle projection, this projection and the locking shift fork engagement that is located at locking swing arm 3 lower ends; One end of locking connector 5 is provided with projection, and in the groove of this projection embedding locking connecting rod 4, the other end places in the groove on the ratchet 2, rotates locking connecting rod 4 locking connector 5 is slided in the groove of ratchet 2.
Introduce the concrete working method of embodiment below according to Fig. 1-4: as shown in Figure 1; Opening handle 1 in triggering when spurring the car door internally-opened handle first rotates around the riveting point; Open handle 1 in rotating to behind the certain angle and promote connecting rod 6 rotations of ratchet 2; As shown in Figure 2, connecting rod 6 rotates to and stops the rotation after ratchet 2 contacts; In open handle 1 and also stir locking swing arm 3 rotations simultaneously, as shown in Figure 3, locking swing arm 3 is meshed through lower end locking shift fork and projection on the locking connecting rod 4; As shown in Figure 1; And then drive 4 rotations of locking connecting rod, and locking connecting rod 4 promotes locking connector 5 through the rod spring 7 that is attached thereto and in the groove of ratchet 2, slides, and locking connector 5 can be stopped by the connecting rod 6 of ratchet 2 behind the slip LAP; And owing to locking connector 5 one ends slide in the groove of ratchet 2; Therefore the connecting rod 6 of ratchet 2 still can continue to rotate to separate lock-bit after locking connector 5 blocked, and rod spring 7 is compressed in this process, and is as shown in Figure 4.When discharging the car door internally-opened handle; In open handle 1 and get back to initial position; The connecting rod 6 of ratchet 2 lock body with spring action under also get back to initial position; Thereby locking connector 5 is stopped that no longer under the active force of rod spring 7, locking connector 5 continues in the groove of ratchet 2, to slide into unlocked position.So far, open two opening device has been accomplished release after spurring the car door internally-opened handle for the first time operations of drawing back in the utility model.
When for the second time spurring inside door handle, open connecting rod 6 rotations that handle 1 promotes ratchet 2 once more in said, locking swing arm 3 owing in pulling first, be rotated to separating lock-bit is no longer stirred by the interior handle 1 of opening.The connecting rod 6 of ratchet 2 rotates to certain angle and promotes locking connector 5, and locking connector 5 opposite sides continue to promote ratchet 2 and rotate to an angle, thereby has accomplished the unlatching of car door.
The above only is the preferred implementation of the 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 improve the protection domain that also should be regarded as the utility model.
