Description
Technical field
The utility model relates to hand-manipulating of needle timepiece movement, relates in particular to a kind of multi-functional hand-manipulating of needle timepiece movement that adopts stepper motor to start.
Background technology
Existing hand-manipulating of needle timepiece movement provides the pulse of a fixed width usually, is used for the rotor of drive stepping motor, and the gear that drives on the driving-chain rotates.Adopt the technology of fixed pulse width drive stepping motor to have following several problem: when adopting the pulsed drive stepper motor of big width, the complete machine electric current is big, power consumption is bigger, so battery is short serviceable life; When adopting the pulsed drive stepper motor of less width, the discreteness of stepper motor coil parameters is bigger, there is the coil parameter of some stepper motors to be in the stepper motor at parameter area edge, sometimes can't be driven accurately, cause hand-manipulating of needle timepiece movement to shut down, stop steathily or walk to wait slowly phenomenon, thereby cause product percent of pass to descend, have a strong impact on product quality; When the gear on the driving-chain that stepping motor rotor drove was subjected to unexpected resistance, hand-manipulating of needle timepiece movement also can shut down, stop steathily or walk slowly, may influence properties of product.
Summary of the invention
The utility model purpose is to provide a kind of self-regulating multi-functional hand-manipulating of needle timepiece movement of driving pulse width of stepper motor.
The purpose of this utility model is achieved through the following technical solutions: hand-manipulating of needle timepiece movement comprises stepper motor, driving-chain and wiring board, stepper motor is provided with inductive coil, stator and rotor, rotor is connected with driving-chain, wiring board is provided with CPU, inductive coil is connected on the CPU, and wherein the width of CPU output pulse is more than one.
The utility model adopts above structure, under common duty, and the pulse of a little width of CPU output, the rotor of drive stepping motor, when the rotor transmission ran into big resistance, the induced voltage of inductive coil was undesired, and sensing is given CPU, CPU exports the rotor of the pulsed drive stepper motor of a big level width, if the rotor transmission still is obstructed, inductive coil continues sensing and gives CPU, the pulse of the bigger level width of CPU output, the rotor of drive stepping motor is until the normal transmission of rotor.After the normal transmission of rotor, the inductive coil sensing is given CPU, and CPU output pulse reverts to the pulse of the little width of former output again, keep the state of operate as normal, so the utility model product power consumption is little, the battery long service life.Because the output pulse of CPU can be adjusted automatically; stepper motor is broken down all resistance; just overcome the time hand-manipulating of needle timepiece movement that causes that gear that the stepping rotor of existing hand-manipulating of needle wrist-watch driven is subjected to unexpected resistance and shut down, stopped steathily or walked to wait slowly phenomenon, thereby improved the qualification rate of product.More than simple in structure, low-cost, and automatically the regulating impulse width is reliable and stable.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further elaborated:
Fig. 1 is the structural representation of the utility model hand-manipulating of needle timepiece movement.
Embodiment
As shown in Figure 1, the utility model comprises stepper motor 1, driving-chain 2 and wiring board 3, stepper motor 1 is provided with inductive coil 11, stator 12 and rotor 13, rotor 13 is connected with driving-chain 2, wiring board 3 is provided with CPU31, and inductive coil 11 is connected on the CPU31, and wherein the width of CPU31 output pulse is more than one, according to the voltage condition of inductive coil 11 sensings, the pulse of output different in width.Under common duty, the pulse of a little width of CPU31 output, the rotor 13 of drive stepping motor 1, gear on the drive underdrive chain 2 of rotor 13 rotates, be reflected on the hand-manipulating of needle of hand-manipulating of needle timepiece movement output, when rotor 13 transmissions run into big resistance, the induced voltage of inductive coil 11 is undesired, sensing is given CPU31, CPU31 exports the rotor 13 of the pulsed drive stepper motor 1 of a big level width, if rotor 13 transmissions still are obstructed, inductive coil 2 continues sensing and gives CPU31, the rotor 13 of the pulsed drive stepper motor 1 of the bigger level width of CPU31 output is until rotor 13 normal transmissions.After rotor 13 normal transmissions, inductive coil 2 sensings are given CPU31, and CPU31 output pulse reverts to the pulse of the little width of former output again, keep the state of operate as normal.So can realize CPU31 output pulse width is regulated automatically.
