The utility model discloses a kind of auto-unlocking device, comprise motor, worm screw, the worm gear of cam face, lever, spring, snap close, described motor connects described worm screw, described worm screw engages with described worm gear, described lever is fixed by fulcrum, described lever one end is hook-shaped, described lever other end lower limb is the curved surface matched with the cam face of described worm gear, top edge offers draw-in groove, described spring upper end is fixed and is placed in described draw-in groove to described lever mineralization pressure, described hook-shaped and described snap close button is taken, lever described in lifting after described worm gear wheel, make described hook-shaped and described snap close lock-off.The utility model has the advantages that employing is electronic and realize automatic unlocking with mechanical chain mechanism, this tripper compact conformation, effectively can complete that snap close button is taken, the action of lock-off, and all can not produce obvious sound when execution, more meet the user demand of high-end product.
Description
Technical field
The utility model relates to a kind of tripper.
Background technology
Along with high-endization of household appliances develops, the more and more automation of many household electrical appliance, intellectuality.Such as some refrigerators, not used for grasping the handle opening and closing door in refrigerator doors, the substitute is a button associated with snap close, press this button and can control snap close unblock.
More high-end, also have now and to be controlled by the input of sound, light or other signal that snap close unlocks, button all without the need to setting, can unlock snap close to after input signal identification.This just needs corresponding auto-unlocking device, controls snap close and unlocks.
Utility model content
Utility model object: for the problems referred to above, the purpose of this utility model is to provide a kind of auto-unlocking device opening lock catch of door lock, after recognizing input signal, can unlock snap close, be opened by door.
Technical scheme: a kind of auto-unlocking device, comprise motor, worm screw, the worm gear of cam face, lever, spring, snap close, described motor connects described worm screw, described worm screw engages with described worm gear, described lever is fixed by fulcrum, described lever one end is hook-shaped, described lever other end lower limb is the curved surface matched with the cam face of described worm gear, top edge offers draw-in groove, described spring upper end is fixed and is placed in described draw-in groove to described lever mineralization pressure, described hook-shaped and described snap close button is taken, lever described in lifting after described worm gear wheel, make described hook-shaped and described snap close lock-off.
Also comprise reference column, described reference column is arranged at described worm gear side, turns to play position-limiting action to worm gear, prevents worm gear wheel angle excessive.
Also comprise gear pair, described motor is connected between described worm screw and is connected by gear pair speed change.When motor force be not enough to direct lifting play lever time, adopt gear pair speed change, increase force.
Also comprise housing, be the carrier that parts are fixing, the fulcrum, spring, snap close, reference column etc. of motor, worm gear, lever are all fixed on housing.
Described motor is direct current generator.
Beneficial effect: compared with prior art, the utility model has the advantages that employing is electronic and realize automatic unlocking with mechanical chain mechanism, this tripper compact conformation, effectively can complete that snap close button is taken, the action of lock-off, and all can not produce obvious sound when execution, more meet the user demand of high-end product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model at blocking;
Fig. 3 is the structural representation of the utility model at released state.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of auto-unlocking device, comprises motor 1, worm screw 2, worm gear 3, lever 4, spring 5, snap close 6, reference column 11, housing 13.Worm gear 3 is cam face.
Motor 1 is connected with worm screw 2, and worm screw 2 engages with worm gear 3.Lever 4 is fixed in housing 13 by fulcrum 7, lever 4 one end is hook-shaped 8, interact with snap close 6, the lower limb of lever 4 other end is curved surface 9, this curved surface 9 matches with the cam face of worm gear 3, top edge offers draw-in groove 10, and spring 5 upper end is fixed in housing 13, lower end is placed in draw-in groove 10, and the elastic force of spring 5 forms downward pressure to lever 4.
Motor 1 is direct current generator, works after accepting the input signals such as photoelectricity.When motor 1 works, worm screw 2 drives worm gear 3 to rotate, worm gear 3 turn to the spring terminal upwards lifting making lever 4, reference column 11 is arranged at worm gear 3 side, has turned to position-limiting action to worm gear 3.
As shown in Figure 2, when not having input signal, motor does not work, and now snap close and hook are taken, and spring makes to buckle to the pressure that lever is downward and takes firmly, and worm gear is yawing moment shown in figure, and reference column is spacing to worm gear, and door lock is in blocking.
As shown in Figure 3, when having input signal, motor is started working, and drive worm screw, worm gear, worm gear is turn to counterclockwise in figure, and by the upwards lifting of the right-hand member of lever during rotation, lever is with fulcrum, and the hook-shaped and snap close lock-off of lever left end, door lock is in released state.
Motor can directly drive worm screw to rotate, and also worm screw can be driven to rotate by gear pair 12, gear pair plays the effect of speed change, when motor force be not enough to directly to drive worm screw, worm gear carry out lifting lever time, the speed change of gear pair can the output of increase force.
