Description

A kind of dead lock of central controlled lock
Technical field
The utility model relates to a kind of ingredient of motor central lock, the dead lock of a kind of central controlled lock of more specifically saying so.
Background technology
Motor central lock gives dead lock a signal by controller, dead lock work, and drivening rod rotates, and connecting rod drive locking device makes on the car door lock again.State Intellectual Property Office's on October 5th, 2008 disclosed " a kind of latch-up structure of automobile door lock " (publication number: CN201133153) locking device is introduced.
Dead lock is the important component part of motor central lock, existing dead lock comprises drive motors, gear and the connecting rod driving wheel that is arranged in the dead lock housing, drive motors and gear, gear and connecting rod driving wheel are in transmission connection respectively, signal by controller, make drive motors work, rotate the unlatching of the latch-up structure of Control of Automobile door lock and locking then by gear driven connecting rod driving wheel.In above-mentioned dead lock, between gear and dead lock housing, be provided with back-moving spring, can guarantee that so each execution action backgear and connecting rod driving wheel are returned to initial position, in the existing dead lock, back-moving spring between gear and the dead lock housing takes an end and the gear of spring to fix again mostly, the other end and dead lock housing are fixed, and have deficiencies such as complex structure, installation trouble.
The utility model content
Be topic at above-mentioned, the problem that the utility model quasi-solution is determined provides the dead lock of back-moving spring between a kind of gear and dead lock housing central controlled lock simple in structure, easy for installation.
For achieving the above object, the utility model is by the following technical solutions: a kind of dead lock of central controlled lock, and it comprises the dead lock housing, is arranged on drive motors, worm screw, worm gear and connecting rod driving wheel in the dead lock housing, described drive motors is connected with worm-drive, described worm and wheel engagement; Be fixed in the dead lock housing in that described worm gear is rotatable, be fixed with coaxial transition gear on the described worm gear, described connecting rod driving wheel is fan-shaped, has dentation on the fan-shaped camber line of described connecting rod driving wheel, the dentation of described connecting rod driving wheel and transition gear engagement, described connecting rod driving wheel is provided with the connecting rod output, the structure that can change fixing at described worm gear and dead lock housing is: a side of described worm gear is provided with columniform worm gear mounting blocks, described dead lock inner walls is provided with the worm gear installing hole, described worm gear mounting blocks is in the worm gear installing hole, be provided with spring block in the described worm gear installing hole, described spring block is in the worm gear mounting blocks outside; The side face of described worm gear mounting blocks is provided with projection; The described spring block outside is provided with back-moving spring, and two ends of described back-moving spring bend inwards, and abuts against two sides of projection of the side face of worm gear mounting blocks.
Two ends stating back-moving spring bend inwards, and the two side worm gears of projection that abut against the side face of worm gear mounting blocks are when rotating, the projection of the side face of worm gear mounting blocks is also rotated thereupon, a wherein side of projection props up one of them end of back-moving spring and rotates, and another end of back-moving spring is blocked by the spring block in the worm gear installing hole, spring twists, and the power that drives on worm gear disappears, and the restoring force of back-moving spring makes worm gear be returned to initial position.The dead lock of the utility model central controlled lock simple in structure, when worm gear is installed, as long as two ends of back-moving spring are stuck in the worm gear mounting blocks projection and side is installed very convenient.
Description of drawings
Fig. 1 is the structural representation of the dead lock of the utility model central controlled lock;
Fig. 2 is the johning knot composition of worm gear and dead lock housing;
Fig. 3 is that Fig. 2 overlooks the direction structure schematic diagram.
Among the figure: 1-dead lock housing, 2-drive motors, 3-worm screw, 4-worm gear, 5-transition gear, 6-connecting rod driving wheel, 7-connecting rod output, 8-worm gear installing hole, 9-spring block, 10-worm gear mounting blocks, 11-back-moving spring, two ends of 12-back-moving spring, 13-projection.
The specific embodiment
As shown in Figure 1, the dead lock of the utility model central controlled lock comprises dead lock housing 1, is arranged on drive motors 2, worm screw 3, worm gear 4 and connecting rod driving wheel 6 in the dead lock housing 1, and described drive motors 2 is in transmission connection with worm screw 3, described worm screw 3 and worm gear 4 engagements.Described worm gear 4 rotatable being fixed in the dead lock housing 1, be fixed with coaxial transition gear 5 on the described worm gear 4, described connecting rod driving wheel 6 is fan-shaped, has dentation on the fan-shaped camber line of described connecting rod driving wheel 6, the dentation of described connecting rod driving wheel 6 and transition gear 5 engagements, described connecting rod driving wheel 6 is provided with connecting rod output 7.The dead lock of the central controlled lock of said structure and prior art does not have essential distinction, therefore no longer launches.
Referring to Fig. 2, Fig. 3, the characteristics of the dead lock of the utility model central controlled lock are: described worm gear 4 with the structure that dead lock housing 1 can change fixing is: a side of described worm gear 4 is provided with columniform worm gear mounting blocks 10, described dead lock housing 1 inwall is provided with worm gear installing hole 8, described worm gear mounting blocks 10 is in worm gear installing hole 8, be provided with spring block 9 in the described worm gear installing hole 8, described spring block 9 is in worm gear mounting blocks 10 outsides; The side face of described worm gear mounting blocks 10 is provided with projection 13; Described spring block 9 outsides are provided with back-moving spring 11, and two of described back-moving spring 12 ones at ends bend inwards, and abut against two sides of projection 13 of the side face of worm gear mounting blocks 10.Described protruding 13 two sides are the inclined-plane, and promptly two sides of projection 13 and the radial direction of worm gear mounting blocks 10 have angle, make two ends 12 of back-moving spring be not easy to break away from protruding 13 sidewalls like this.
