Description

Voice-controlled single-motor double-rail direct-current electric opening and closing curtain system

Technical Field

The utility model relates to a voice-controlled single-motor double-track direct-current electric curtain opening and closing system, in particular to a direct-current electric curtain opening and closing device which makes the overall dimension of a curtain motor of the direct-current electric curtain opening and closing system small; the direct current electric curtain system is developed and designed on the basis of the invention patent ZL201310470601.4 and the invention patent application scheme with the application number of 201810893968.X, and can control a single motor to drive two sets of curtains under double tracks to open and close in a one-way or two-way mode in a voice mode; the automatic two-way clutch is driven by a synchronous belt, joints connecting two ends of the synchronous belt and a pulley main body are designed into a whole, and the automatic two-way clutch has a voice control function and a remote control function by applying an aluminum alloy double rail described in the invention patent ZL201310470601.4 and the mechanical two-way automatic clutch in the invention patent application scheme with the application number of 201810893968. X.

The voice control method comprises the following steps: 6 awakening names are configured for each electric curtain opening and closing motor, and are respectively as follows: kitten, pineapple, duck, small jingle, little baby hello, little shellfish hello; wake name + wake word-command. The 'awakening name' and the 'awakening word' are burnt in the chip of the voice control module in advance.

Through the awakening name setting function, a user can set different awakening names for electric curtain opening and closing motors at different positions on the same occasion in a voice mode; when the awakening name is set once, the awakening name is broadcasted with voice, so that a user can know the awakening name of the current curtain motor; the awakening words of all the electric curtain opening and closing motors are the same, and the awakening name is used for awakening the electric curtain opening and closing motors at different positions.

After the user sets the awakening name, the set of direct-current electric curtain opening and closing system can be controlled at will only by saying the awakening name and the awakening word in daily life. For example: when a user sets the awakening name of the current curtain motor to be the small cat, the curtain motor simultaneously broadcasts the ' hello, i.e. the small cat ' through voice, namely the awakening name of the direct-current electric opening and closing curtain motor is called the small cat '.

After the awakening name is set, the user only needs to stand in the identification distance range allowed by the curtain motor in daily life: the small cat responds with the 'jinjinjinding' sound instantly to indicate that the curtain motor is in an awakening state, and when a user then says 'open the curtain', the curtain motor starts to work to open the curtain; and so on: the set of direct current electric curtain system can be controlled by using similar instructions of 'small jingle' + 'closing the curtain', 'small duck' + 'stopping', 'small pineapple' + 'opening half', 'small baby hello' + 'closing one third', 'small baby hello' + 'opening one point', and the like.

When a user does not want to call the current 'awakening name' and 'kitty' of the electric opening and closing curtain motor any more, the 'awakening name' of the curtain motor can be changed at any time in a 'voice' mode; the operation method comprises the following steps: the user stands in an allowed distance to say 'kitten', the curtain motor instantly responds with 'jinjinding' sound, the user then says 'change of name', the curtain motor instantly responds with 'jinding' sound again, the user then says 'pineapple', and the curtain motor can instantly report 'you are good, i.e. the user is pineapple', namely, the curtain motor is successfully called 'pineapple'.

The plastic shell of the curtain motor is directly contacted with the plastic transmission case and the plastic positioning plate, and the plastic shell, the plastic transmission case and the plastic positioning plate are in rigid connection. The metal motor base and the metal noise shielding cover are in interference fit.

The plastic shell and the plastic positioning plate of the curtain motor are not directly contacted with the metal motor base and the metal shielding cover, and elastic pieces are padded between the plastic shell and the plastic positioning plate and are elastically connected; the metal motor base and the metal shielding cover are not in direct contact with the metal planetary gear speed reducing motor, and elastic parts are arranged among the metal motor base and the metal shielding cover and are in elastic connection.

The T-shaped hollow screw damping cushion is sleeved on a metal screw for fixing a metal planetary gear reduction motor box body, a metal motor base and a metal noise shielding cover; the I-shaped hollow vibration-damping rubber pad is sleeved on a metal self-tapping nail used for fixing a metal motor base, a plastic positioning plate and a plastic transmission case, so that the parts are isolated by the vibration-damping rubber pad.

Background

At present, the output rotating speed of a planetary gear speed reducing motor of a direct current electric curtain opening and closing motor in the market is between 70 rpm and 130 rpm. In order to reduce the operating noise of the planetary gear speed reducing motor, a planetary gear speed reducing box driven by a plastic gear is generally adopted. Under the condition of the same volume size, the torque transmitted by the plastic gear is smaller than that transmitted by the metal gear.

At present, the starting rotating speed of a direct current motor used by a direct current electric curtain opening and closing motor on the market is 2000-4000 rpm. Under the condition that the required output rotating speed is the same, the lower starting rotating speed of the direct current motor limits the reduction ratio of the planetary gear reduction box, so that the larger output torque cannot be obtained by a larger reduction ratio.

When the planetary gear speed reducing motor driven by the plastic gear and the planetary gear speed reducing motor driven by the metal gear have the same output torque, the plastic gear with the larger volume than the metal gear and the direct current motor with the relatively larger diameter and the relatively larger volume need to be selected, so that a main control panel and a variable voltage power supply in a traditional electric opening and closing curtain motor shell cannot be transversely arranged in parallel with the planetary gear speed reducing motor in the limited space in the motor shell.

The traditional main control board and the variable voltage power supply inside the direct current electric opening and closing curtain motor shell are arranged at the tail end of the planetary gear speed reduction motor in a longitudinal vertical column mode due to the fact that the planetary gear speed reduction box made of plastic materials is overlarge in size, the direct current motor is low in starting rotating speed, large in output torque, large in diameter and large in size, the length of the main control board and the variable voltage power supply are usually as long as more than 30 cm, even 36 cm, and the weight of the direct current motor is usually 1.2-1.6 kilograms.
