Description

Noiseless dynamo-electric alarm clock

Technical field

The utility model relates to a kind of daily alarm clock, particularly relates to a kind of noiseless dynamo-electric alarm clock.

Background technology

Alarm clock has served as irreplaceable role in people's life.Though present panoramic alarm clock is more and more, the alarm clock function of mobile phone is also very convenient.But, when alarm clock sounds,, also can bother, have influence on other people inevitably and have a rest, even if the vibrating mode of alarm clock also is like this except having waken the user because people are not solitary generally.

Number of patent application is 201220118295.9 intelligent machine electric alarm clock; Comprise the clock body and wake pillow up; Wake up Vib. is installed in the pillow, the Zhong Tiyu Vib. connects, and a plurality of pressure transducers are installed in waking pillow up; A plurality of pressure transducers are arranged to the pressure sensing electric bridge, and the pressure sensing electric bridge is connected with the clock body.This intelligent machine electric alarm clock just can judge whether the litigant gets up; If the litigant does not get up, the intelligent machine electric alarm clock will be at the moment Vibration on Start-up device of setting, if the litigant gets up; Both made waking constantly of setting; The intelligent machine electric alarm clock can the Vibration on Start-up device yet, and this intelligent machine electric alarm clock can judge whether the litigant gets up, and wakes the litigant easily and leave other people alone.

Though being 201220118295.9 intelligent machine electric alarm clock, number of patent application can judge whether the litigant gets up; And wake the litigant easily and leave other people alone; But because the Vib. of this intelligent machine electric alarm clock is made up of base, motor, reduction gear, connecting rod crank mechanism and oscillating plate, motor mounting is on base, and motor is connected with the clock body; The input end of reduction gear is connected with the output shaft of motor; The crank of connecting rod crank mechanism is connected with the output terminal of reduction gear, and oscillating plate is connected with the connecting rod of connecting rod crank mechanism, in actual use; The mechanical friction noise of its reduction gear and connecting rod crank mechanism is big, and this mechanical friction noise still can be bothered other people; Simultaneously, two pairs of gears in the reduction gear of this intelligent machine electric alarm clock and regular meeting of connecting rod crank mechanism are stuck job insecurity because of unbalance stress.

Summary of the invention

The purpose of the utility model provides a kind of noiseless dynamo-electric alarm clock, and the mechanical friction noise was little when this noiseless dynamo-electric alarm clock was worked, and can not bother other people.

In order to achieve the above object, the noiseless dynamo-electric alarm clock of the utility model comprises the clock body and wakes pillow up; Wake up Vib. is installed in the pillow, the Zhong Tiyu Vib. connects, and wakes up a plurality of pressure transducers are installed in the pillow; A plurality of pressure transducers are arranged to the pressure sensing electric bridge, and the pressure sensing electric bridge is connected with the clock body, and Vib. is made up of base, motor, gear train and oscillating plate; Motor mounting is on base, and motor is connected with the clock body, and oscillating plate is movably articulated on the base; Gear train is connected between motor and the oscillating plate, it is characterized in that: gear train is a pulley blocks.

Because gear train is a pulley blocks, in the pulley blocks be with wire rope as pulling force spare, do not have noise or noise very little in the course of the work, so the noiseless dynamo-electric alarm clock operating noise of the utility model is little, can not bother other people; Simultaneously, because do not have gear drive and connecting rod crank mechanism driving in the gear train, can not be stuck because of unbalance stress, working stability is reliable.

Described noiseless dynamo-electric alarm clock; It is characterized in that: gear train is reverse two pulley blockss installing; Pulley blocks comprises fixed pulley, travelling block and wire rope, and fixed pulley is installed on the base of Vib., and the travelling block of two pulley blockss is connected with the oscillating plate two ends of Vib. respectively with wire rope.

The mechanical friction noise was little when the noiseless dynamo-electric alarm clock of the utility model was worked, and can not bother other people, and working stability is reliable.
