Description

The scanning electron alarm clock movement

The utility model relates to a kind of electronic clock product, especially a kind of scanning electron alarm clock movement.

It is pulse per second (PPS) that present widely used pointer electron quartz clock product all adopts the fixed frequency pulse frequency division that quartz oscillator is produced, and drives a stepper motor with pulse per second (PPS) again and drives the pointer rotation.Therefore, rotatablely moving of second hand is not continuous, fixing angle of the rotation but per second is beated (second jumping).Time was continuously the physical quantity of passage originally, did not meet the common visual custom of people instruction time by the pin of beating second.In addition, when the travel mechanism of pointer electron quartz clock rotatablely moves in a do second jumping, owing to exist between reduction gearing the gap to cause impact between gear teeth, second hand with certain moment of inertia is handled the needle with step-by-step system and is caused self and affect gear vibration to cause that between cog impacts, the axial force that gear drive produces also causes the impact between gear and last lower plate, more than impacts all producing impact noise.

The purpose of this utility model provides a kind of alarm clock product that is scanning electron alarm clock movement, and in the hope of realizing that second hand is handled the needle continuously, noiseless effect when alarm clock is walked.

The purpose of this utility model is achieved in that a kind of scanning electron alarm clock movement, comprise battery, wherein, described battery with by quartz oscillator, frequency division and motor-drive circuit, motor, reducing gear train, Hour Minute Second and the scanning electron alarm clock movement line that indicating mechanism, timing mechanism, acoustical generator constitute when making a noise be connected, wherein, described frequency division and motor-drive circuit are 4～16Hz with the fixed frequency electricity arteries and veins frequency division that quartz oscillator produces, and motor is continuous electric rotating machine.

Adopt the scanning electron alarm clock movement to keep that ordinary electronic quartz clock physical construction is simple, the advantage of punctual timing, overcome the shortcoming that impact noise is arranged when its second hand is beated walking again, no longer produce shock and vibration between the between cog of gear, gear and last lower plate, the pointer smooth running, embodied the continuity of time, watch comfortable, silent when walking, do not influence people's rest and sleep.

Below in conjunction with drawings and Examples in detail the scanning electron alarm clock movement that the utility model relates to is described in detail again.

Fig. 1 is the theory structure block diagram of prior art pointer electron quartz clock movement.

Fig. 2 is the theory structure block diagram of the utility model scanning electron alarm clock movement.

Fig. 3 is gear reducing gear figure between the motor of an embodiment of the utility model and second wheel

By Fig. 2, Fig. 3 and with reference to figure 1 the utility model is a kind of scanning electron alarm clock movement, comprise battery, wherein, described battery with by quartz oscillator, frequency division and motor-drive circuit, motor, reducing gear train, Hour Minute Second and the scanning electron alarm clock movement line that indicating mechanism, timing mechanism, acoustical generator constitute when making a noise be connected, wherein, described frequency division and motor-drive circuit are 4～16Hz with the fixed frequency electricity arteries and veins frequency division that quartz oscillator produces, and motor is continuous electric rotating machine.Described frequency division and motor-drive circuit output frequency are the electric pulse of 8Hz.Described reducing gear train comprises gear 3, second wheel 4, rotor 1 and reduction gearing 2, wherein, the axle tooth of rotor 1 with and the gear 3 that links to each other of second wheel 4 between increase reduction gearing 2, making the ratio of gear of the gear train that a tooth of rotor 1 and gear 2,3 and second wheel 4 constituted is 1: 480.The walking of jumping of pulse per second (PPS) frequency dividing circuit and the stepper motor that in existing pointer electron quartz clock movement product, uses as shown in Figure 1, second hand.The alarm clock product that relates to of the utility model is that the scanning electron alarm clock movement uses 4～16Hz frequency dividing circuit and electric rotating machine continuously as shown in Figure 2, makes the second hand continuous walking.Arabic numeral among the figure 1 are the rotors of continuous electric rotating machine as shown in Figure 3, and 2 and 3 is reduction gearing, and 4 is the second wheel of walking time part.The frequency dividing circuit of present embodiment is converted to 8Hz with the fixed frequency electric pulse of quartz oscillator output, rotates continuously through the synchronous rotational speed of power amplification drive motor rotor 1 with 8 revolutions per seconds.The axle tooth of rotor 1 and with gear 3 that second wheel 4 links to each other between increase reduction gearing 2, making the ratio of gear of the gear train that a tooth of rotor 1 and gear 2,3 and second wheel 4 constituted is 1: 480.

The alarm clock product that the utility model of describing with technique scheme and embodiment relates to: the scanning electron alarm clock movement, if at present as can be known, do not have discovery in the home and abroad horological industry that can retrieve.Therefore, this product is a kind of novel product that can replace the pointer electron quartz clock fully.
