Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
Referring to Fig. 1, Fig. 2, present embodiment discloses a kind of device that can realize refrigerator automatic opening and closing door, refrigerator includes case
Body 1 and door body 2, device include arc chain bar 3, driving gear 4, driven gear 5, spacing fast pulley 6, motor 12 and controller,
The inner side of arc chain bar 3 is provided with multiple internal tooths, and arc chain bar 3 is horizontal to be located between door body 2 and casing 1, and the one end of arc chain bar 3 is consolidated
It is scheduled in door body 2, the other end is extended in the accommodating cavity at the top of casing 1, driving gear 4, driven gear 5, spacing fast pulley
6th, motor 12 and controller are installed in the accommodating cavity at the top of casing 1, driving gear 4, driven gear 5 and arc chain
The internal tooth of bar 3 is meshed successively, and the number of teeth of driving gear 4 is less than the number of teeth of driven gear 5, and driven gear 5 is used as reduction gearing, can dropped
The slow-speed of revolution and increase torque.Driving gear 4, driven gear 5 are rotatably arranged in accommodating cavity respectively, and driven gear 5 and limit
Position fast pulley 6 is located at the inner side and outer side of arc chain bar 3 respectively, and spacing fast pulley 6 is by a spring support 7 tight against in arc
The outside of chain bar 3 causes driven gear 5 to be meshed all the time with arc chain bar 3, can effectively prevent arc chain bar 3 and driven gear 5
It is relative during effect to slide or come off.Driving gear 4 be arranged on motor 12 output shaft on, motor 12 be electrically connected with the controller and by
Control in controller, drive driving gear 4 to rotate by motor 12, so as to drive driven gear 5 to rotate, driven by driven gear 5
Arc chain bar 3 moves, and the movement pulling door body 2 of arc chain bar 3 realizes automatic door opening or the shutdown of door body 2.Motor 12 uses direct current
Motor, direct current generator small power consumption, noise is small, and small volume, structure is easily installed；Output torque is big, output linearity is smooth, gap-ratio
Smaller, no auto-lock function, dynamical output response is rapidly.
Referring also to Fig. 3, controller inside are provided with main control unit 8, driver element 9, the harmony of 12 protection location of motor 10
Unit 11 is controlled, driver element 9, the protection location 10 of motor 12 and audio control unit 11 electrically connect with main control unit respectively, and motor 12 divides
Do not electrically connected with driver element 9, the protection location 10 of motor 12, audio control unit 11 sends sound control signal to main control unit 8, master control
Unit 8 processed issues instructions to driver element 9 according to the sound control signal received, allows driver element 9 to carry out motor 12 and works；Work as electricity
During 12 retard motion of machine, the feedback of motor 12 signal that is obstructed gives the protection location 10 of motor 12, by the protection location 10 of motor 12 transmit by
Resistance signal issues instructions to the driver element 9 of motor 12 to main control unit 8, main control unit 8 according to the signal that is obstructed received, by
The driver element 9 of motor 12 stops motor 12, and motor 12 is stopped.
Wherein, audio control unit 11 has voice identification function, voice store function, can set special messenger's special function, tool
Prevent that children from speaking function, acoustic control regulatory function by mistake, have and identify accurate, good antijamming capability, small power consumption, Ke Yigen
The distance spoken according to demand setting.The protection location 10 of motor 12 can be protected to the overvoltage overcurrent of motor 12, Yi Ji electricity
The stall of machine 12 is protected.The driver element 9 of motor 12 is driven using safety low-voltage, and oneself power consumption is low, output current scope
Greatly, wide input voltage range, self-regulating votage is relatively good, and dynamic response is fast.
After consumer sends switch gate instruction, switch gate instruction can pass to main control unit 8 by audio control unit 11,
Driver element 9 is passed to again, is allowed driver element 9 to carry out motor 12 and is worked accordingly.When motor 12 works, driving gear
4, which rotate drive driven gear 5, rotates, and when 5 rotate counterclockwise of driven gear, driven gear 5 pulls arc chain bar 3 to close to case
The direction motion of body 1, drives door body 2 to close, and spacing fast pulley 6 limits the position of arc chain bar 3 in the process, prevents arc chain
Slip teeth or separated when bar 3 acts on driven gear 5.When door body 2 is closed, the stop motion of door body 2, the retard motion of motor 12, electricity
Machine 12 feeds back the signal that is obstructed and gives the protection location 10 of motor 12, is transmitted by the protection location 10 of motor 12 and is obstructed signal to main control unit
8, main control unit 8 issues instructions to the driver element 9 of motor 12 according to the signal that is obstructed received, is stopped by the driver element 9 of motor 12
Only motor 12, motor 12 are stopped, and realize automatic door-closing.Motor 12 drives enabling operation principle and shutdown operation principle
It is similar.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should be included in the scope of the protection.
