The invention discloses a kind of auto-unlocking device, including 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 passes through fixed pivot, described lever one end is hook-shaped, described lever other end lower limb is the curved surface that the cam face with described worm gear matches, draw-in groove is offered on top edge, fixing being placed in described draw-in groove of described spring upper end forms pressure to described lever, described hook-shaped and described snap close button is made to take, lever described in lifting after described worm gear wheel, make described hook-shaped and described snap close lock-off.It is an advantage of the invention that employing is electronic and realize automatic unlocking with mechanical chain mechanism, this tripper compact conformation, can efficiently accomplish snap close button take, the action of lock-off, and when execution all without produce obvious sound, more meet the use demand of high-end product.
Description
Technical field
The present invention relates to a kind of tripper.
Background technology
Along with high-endization of household appliances develops, many household electrical appliance increasingly automatization, intellectualities.Such as some refrigerators,
Open and close the handle of door in refrigerator doors not used for grasping, the substitute is a button associated with snap close,
Press this button and can control snap close unblock.
More high-end, control what snap close unlocked also by the input of sound, light or other signal now, button all without
Arrange, to unlocking snap close after input signal identification.This needs exist for corresponding auto-unlocking device, controls snap close
Unlock.
Summary of the invention
Goal of the invention: for the problems referred to above, it is an object of the invention to provide a kind of auto-unlocking device opening lock catch of door lock,
After recognizing input signal, snap close can be unlocked, door is opened.
Technical scheme: a kind of auto-unlocking device, including motor, worm screw, the worm gear of cam face, lever, spring,
Snap close, described motor connects described worm screw, and described worm screw engages with described worm gear, and described lever passes through fixed pivot, institute
It is hook-shaped for stating lever one end, and described lever other end lower limb is the curved surface that the cam face with described worm gear matches, on
Offering draw-in groove on edge, fixing being placed in described draw-in groove of described spring upper end forms pressure to described lever, makes described
Hook-shaped and described snap close button is taken, lever described in lifting after described worm gear wheel, makes described hook-shaped and described snap close lock-off.
Also include that locating dowel, described locating dowel are arranged at described worm gear side, worm gear is turned to and plays position-limiting action, prevent
Worm gear wheel angle is excessive.
Also including gear pair, described motor is connected and is connected by gear pair speed change between described worm screw.When motor force is not enough to
When directly lifting plays lever, use gear pair speed change, increase power.
Also include housing, for the carrier that parts are fixing, motor, worm gear, the fulcrum of lever, spring, snap close, locating dowel
Deng being all fixed on housing.
Described motor is direct current generator.
Beneficial effect: compared with prior art, it is an advantage of the invention that employing is electronic and realizes automatically solving with mechanical chain mechanism
Lock, this tripper compact conformation, it is possible to efficiently accomplish snap close button take, the action of lock-off, and when execution all
Obvious sound will not be produced, more meet the use demand of high-end product.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is the present invention structural representation at blocking；
Fig. 3 is the present invention structural representation at released state.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate this
Invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As shown in Figure 1, a kind of auto-unlocking device, including motor 1, worm screw 2, worm gear 3, lever 4, spring 5,
Snap close 6, locating dowel 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, interacts with snap close 6, and the lower limb of lever 4 other end is curved surface 9, this curved surface 9
Matching with the cam face of worm gear 3, top edge offers draw-in groove 10, 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 rotate, worm gear 3 turn to the spring terminal upwards lifting making lever 4, locating dowel 11 is arranged at worm gear 3 side, right
Worm gear 3 turned to position-limiting action.
As shown in Figure 2, when not having input signal, motor does not works, and now snap close is taken with hook, and spring is to lever
Downward pressure makes button take firmly, and worm gear is yawing moment shown in figure, and locating dowel is spacing to worm gear, and door lock is in locking
State.
As shown in Figure 3, when having input signal, motor is started working, and drives worm screw, worm gear, and worm gear is the inverse time in figure
Pin turns to, by the upwards lifting of the right-hand member of lever during rotation, lever with fulcrum, 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, it is also possible to driving worm screw to rotate by gear pair 12, gear pair plays change
The effect of speed, when motor force is not enough to directly drive worm screw, worm gear to carry out lifting lever, the speed change of gear pair can increase power
Output.
