Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide the door lock clutch device in a kind of effective raising door lock application life.
For achieving the above object, the invention provides following technical scheme: a kind of door lock clutch device, comprise clutch, described clutch comprises interior clutch part and outer clutch part, described interior clutch part is rotatable to be arranged in outer clutch part, described interior clutch part is provided with clutch slot, described outer clutch part is provided with on-of pin, described on-of pin is provided with and drives it to stretch into clutch driving mechanism in clutch slot, described on-of pin is also provided with and imposes the return unit with clutch driving mechanism counter force to it, described clutch driving mechanism comprises clutch and promotes arc sheet and drive clutch to promote the driver element that arc sheet presses to on-of pin, the electromagnetic drive unit that described driver element comprises push rod and drives push rod flexible, the relative electromagnetic drive unit other end of described push rod and clutch promote arc sheet and match and arrange.
By adopting technique scheme, electromagnetic drive unit drives push rod to stretch out, and push rod makes clutch promote arc bending tablet to press to on-of pin, on-of pin is headed in clutch slot, thus achieves the interlock of interior clutch part and outer clutch part; Electromagnetic drive unit drives push rod to shrink, and clutch promotes arc sheet and resets, and makes on-of pin leave clutch slot because of the effect of return unit, interior clutch part and outer clutch part is departed from and links.Electromagnetic drive unit has better stability relative to traditional motor drive mode, thus improves the application life of door lock, and advantage of lower cost.
The present invention is arranged further: described interior clutch part is provided with the resetting-mechanism it being imposed to active force, and described active force makes clutch slot aim at the on-of pin position of outer clutch part.
By adopting technique scheme, due to the effect of the internal clutch part of resetting-mechanism, when interior clutch part is resetted, clutch slot can aim at on-of pin position all the time, thus avoids because interior clutch part resets not in place that on-of pin can not insert clutch slot, and the door lock caused can not be opened.
The present invention is arranged further: the periphery wall of described interior clutch part is provided with interior clutch groove, when clutch slot is to corresponding on-of pin position, in the internal perisporium correspondence of outer clutch part, clutch groove location is provided with the outer clutch groove suitable with interior clutch groove length, described interior clutch groove and outer clutch groove form accommodating cavity, be provided with elastic component in described accommodating cavity, described elastic component two ends offset with the circumferential two side of accommodating cavity respectively and arrange.
By adopting technique scheme, due to the effect of elastic component, when interior clutch part is resetted, clutch slot can aim at on-of pin position all the time, thus avoids because interior clutch part resets not in place that on-of pin can not insert clutch slot, and the door lock caused can not be opened.
The present invention is arranged further: described elastic component is set to Compress Spring, and described Compress Spring is that circumference is arranged in described accommodating cavity.
The present invention is arranged further: described clutch also comprises driving tooth, upper rotating shaft, upper square steel, lower rotary shaft, lower square steel, described upper square steel and upper rotating shaft are arranged in linking, described lower square steel and lower rotary shaft, interior clutch part interlock is arranged, described outer clutch part is provided with commutation screw, outer clutch spacing block set and outer clutch drive projection, described upper rotating shaft is provided with the upper rotating shaft male arms with the screw fit that commutates, described driving tooth is provided with the driving tooth male arms driving projection to match with outer clutch part, the side of described clutch is provided with the limiting rivet matched with outer clutch spacing block set.
By adopting technique scheme, when on-of pin is not inserted into clutch slot, lower square steel drives lower rotary shaft, interior clutch part to rotate, and interior clutch part and outer clutch part dally and outer clutch part can not be driven to rotate, thus driving tooth can not be made to rotate, so that door lock can not be opened; When on-of pin is inserted into clutch slot, lower square steel drives lower rotary shaft, interior clutch part to rotate, and interior clutch part and outer clutch part link and drive outer clutch part to rotate, and the outer clutch part of outer clutch part drives projection to drive driving tooth male arms, thus driving tooth is rotated, so that open door lock; And upper square steel is when driving upper axis of rotation, upper rotating shaft male arms and commutation screw fit drive outer clutch part to rotate, the outer clutch part driving projection drive driving tooth male arms of outer clutch part, thus driving tooth is rotated, so that open door lock.
The present invention is arranged further: the upper and lower wall of described outer clutch part is respectively arranged with the installing hole installed for commutation screw be symmetrical set, and described lower rotary shaft is provided with the lower rotary shaft male arms with the screw fit that commutates.
By adopting technique scheme, commutation screw can be arranged on or the installing hole of lower wall surface, make arrangement of clutch can inside and outside general.
The present invention is arranged further: described resetting-mechanism comprises torsion spring, described torsion spring is provided with two bending ends, interior clutch part is provided with two torsion springs and dials pin, and when clutch slot is to corresponding on-of pin position, described two bending ends prop up the adjacent both sides that described two torsion springs dial pin respectively.
By adopting technique scheme, due to the effect of the internal clutch part of torsion spring, when interior clutch part is resetted, clutch slot can aim at on-of pin position all the time, thus avoids because interior clutch part resets not in place that on-of pin can not insert clutch slot, and the door lock caused can not be opened.
The present invention is arranged further: describedly also comprise panel and handle, and described handle is provided through panel and the interlock end linked with outer clutch part, and described torsion spring set is located at outside the interlock end of described handle.
By adopting technique scheme, make firm being arranged in door lock of torsion spring.
