Description

The engagement type car centrally controrlled locking system of a kind of tooth bar

Technical field:

The utility model relates to the engagement type car centrally controrlled locking system of a kind of tooth bar.

Background technology:

Existing automobile-used centrally controrlled locking system mainly adopts centrifugal clutch lock or friction clutch formula lock; Motor output shaft connects flywheel during the work of centrifugal clutch lock, and the clutch structure of flywheel and clutch gear is that the flywheel edge has centrifugal son, when the motor drives flywheel rotates; Centrifugal son stretches out; The drive clutch gear rotates, and makes pull bar flexible through travelling gear, accomplishes the centrally controrlled locking system opening and closing.Centrifugal clutch is latched in centrifugal son and often is stuck and motor short defective in application life.

Motor output shaft drives the friction pulley rotation during friction clutch formula lock machine operation; Rely on boss and recess on clutch gear and the friction pulley to form frictional fit; Rotate thereby drive clutch gear, make pull bar flexible through travelling gear again, accomplish the centrally controrlled locking system opening and closing.The friction clutch formula is latched in the situation of friction pulley and clutch gear generation slippage, causes and can't unblank, and performance is unreliable.

Summary of the invention:

For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of tooth bar engagement type car centrally controrlled locking system, and it is simple and reliable for structure, and energy consumption is low, and the life-span is long.

The utility model technical solution problem adopts following technical scheme:

The engagement type car centrally controrlled locking system of a kind of tooth bar comprises:

Be located in the car body in open handle, by open in said handle drives around first rotating shaft rotate in open the interlock plate;

Relieving mechanism, the center is connected locking/separate in the waist-shaped hole of lock dog through bearing pin, the bottom of said relieving mechanism be provided with said in open the projection that the interlock plate is interfered, the top of relieving mechanism is with can to stop latch hook to rotate an end of the lock ratchet of opening hinged;

The middle part of said lock ratchet is provided with second rotating shaft that is connected on the lock body;

Setting is passed through the tooth bar that gear train drives by the output shaft of motor, and the end of said tooth bar is provided with boss, said locking/separate lock dog to be provided with the groove that fastens with said boss.

Compared with present technology, the beneficial effect of the utility model is embodied in:

1) compares with other locks; It is the rectilinear motion that the rotation of motor output shaft is become the pulling tooth bar through the level Four gear drive that the electronic part of the utility model is unblanked; This design work dependable performance, the lock body integrated level is higher, the less and long service life of volume; The situation that centrifugal clutch lock or friction clutch formula are locked the job insecurity of carrying that brings because of structure design in the course of work can not occur, can satisfy the automobile industry standard requirement.

2) simple and reliable for structure, energy consumption is low, and the life-span is long.

3) cost is lower, and convenient realization is automatically controlled, satisfies vehicle intellectualized needs, is applicable to the volume production demand.

Description of drawings:

Fig. 1 is the schematic diagram of the automatically controlled release of the utility model, locking; Fig. 2 is the section of rack master TV structure sketch map of motor, gear train and the driving of the utility model central controlled lock; Fig. 3 is the right TV structure sketch map of the utility model central controlled lock; Fig. 4 is in the structural representation under the released state for lock body; Fig. 5 is in the structural representation under the lockup state for lock body.

Label among the figure: open handle in 1,2 relieving mechanisms, 3 lockings/separate lock dog is opened the interlock plate, 5 projections, 6 lock ratchets, 7 first rotating shafts, 8 second rotating shafts, 9 latch hooks, 10 the 3rd rotating shafts, 11 bearing pins, 12 motors, 13 gear trains, 14 tooth bars, 15 motor output shafts in 4.

Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.

The specific embodiment:

Embodiment: combine Fig. 1-5, the engagement type car centrally controrlled locking system of the tooth bar of present embodiment comprises:

Be located in the car body in open handle 1, by interior open handle drives around first rotating shaft 7 rotate in open interlock plate 4;

Relieving mechanism 2, the center is connected locking/separate in the waist-shaped hole of lock dog 3 through bearing pin 11, the bottom of relieving mechanism 2 be provided with in open the projection 5 that interlock plate 4 is interfered, the top of relieving mechanism 2 is with can to stop latch hook 9 to rotate an end of the lock ratchet of opening 6 hinged; The middle part of lock ratchet 6 is provided with second rotating shaft 8 that is connected on the lock body; Setting is passed through the tooth bar 14 that gear train 13 drives by the motor output shaft 15 of motor 12, and the end of tooth bar 14 is provided with boss, locking/separate lock dog 3 to be provided with the groove that fastens with boss.

The principle of automatically controlled release, locking: show like Fig. 1,3,5, when door lock is in lockup state, open handle 1 in the pulling or the external-open handle car door can not be opened; When the locking key of separating of pressing remote-control key; Transmit unlocking signal through the chip in the key and give automobile controller BCM, by the release end terminal A of BCM with the positive pole connection car door lock of power supply, power cathode is connected the locked end terminal B of door lock again; Rotating band moving gear group 13 through motor 12 rotates then; Get up through gear train driving-belt carry-over bar 14 motion,, thereby make the car door lock release again by tooth bar pulling locking/separate lock dog 3; At this moment only need to open handle 1 or external-open handle in the pulling, car door just can be opened; Concrete action is: when opening lock; In open handle 1 and open interlock plate 4 in driving and rotate around first rotating shaft 7; In open the interlock plate 4 front end block projection 5 and drive relieving mechanism 2 descending; Relieving mechanism 2 drives lock ratchet 6 and breaks away from around second rotating shaft, 8 rotations and with latch hook 9, and latch hook 9 is broken away from the interference of lock ratchet 6 and rotated around the 3rd rotating shaft 10, thereby door lock is opened.

Does when being in released state, how car door implement automatically controlled locking behind closing of the door? In like manner; At this moment can press the blocking wedge of remote-control key, transmit block signal through the chip in the key and give automobile controller BCM, by BCM the positive pole of power supply connected the locked end terminal B of car door lock again; Power cathode is connected the release end terminal A of door lock, rotates through the rotating band moving gear group of motor 12 then, moves through gear train driving-belt carry-over bar; Again by tooth bar pulling locking/separate lock dog; Shown in Figure 5, locking/separate lock dog 3 to promote relieving mechanism 2 makes the interference of opening interlock plate 4 in projection 5 disengagings; Thereby make the car door lock locking, at this moment open handle 1 or external-open handle just can not be with car door opening in the pulling again.
