Lockset is a kind of utensil that can seal door leaf, can make illegal molecule arbitrarily not enter indoor.But the inartful to lockset of grasping along with illegal molecule is opened the raising of ability, and some lockset can adopt nonconventional approaches to be unlocked easily, have to pick-proof to lockset, crashproof, anti-plug performance of people proposes more and more higher requirement for this reason.And electronic lock is more and more subject to modern's favor with its peculiar safety, convenience.In current electronic lock field, one of them means that improves its safety are, in the drive path between door handle and dead bolt, clutch is set, and the structure of described clutch exists various structures form at present.
The for example prior art patent No. is 201020607497.0, the applying date is on June 1st, 2011, patent name is the Chinese utility model patent of " electronic lock clutch ", disclosed a kind of lock clutch, comprised with the clutch outer ring 7(of outer handle interlock and have another name called outer clutch block), have another name called interior clutch block with the free rolling ring 8(of Internal handle interlock), on-of pin 9 and on-of pin driving mechanism.Wherein, described free rolling ring 8 is rotationally connected with in the hole of described clutch outer ring 7 and can relatively rotates with described clutch outer ring 7; Side in described clutch outer ring 7 is provided with clutch key seat 701, and described on-of pin 9 floats and is arranged in described clutch key seat 701 and on on-of pin 9, is set with the back-moving spring that makes it outwards reset.And be provided with the pin-and-hole corresponding with on-of pin 9 in free rolling ring 8.And the output setting of on-of pin driving mechanism has the on-of pin push jack 5 of arc medial surface.Described in driving mechanism task driven, on-of pin push jack 5 moves forward and promotes described on-of pin 9, after pressing described back-moving spring, described on-of pin 9 tops enter described pin-and-hole, now described clutch outer ring 7, free rolling ring 8 forms interlock, unblanks thereby can drive free rolling ring 8 to rotate to complete while rotating described clutch outer ring 7.Meanwhile described on-of pin 9 also rotates with described free rolling ring 8 and keeps mutual top pressure condition with the arc medial surface of described on-of pin push jack 5.And thereby drive unit reversion drives described on-of pin push jack 5 to retreat to reset the interaction relationship of eliminating described on-of pin push jack 5 the top pressure effect of described on-of pin 9 has been eliminated between described on-of pin push jack 5 and described on-of pin 9 in other words power, now described on-of pin 9 resets and leaves described pin-and-hole under the elastic acting force of described back-moving spring, now in slipping state, between them, there is not interaction relation in described clutch outer ring 7, free rolling ring 8.
And for example prior art patent No. is 200920132323.0, the applying date is on June 1st, 2009, and the Chinese utility model patent that patent name is " clutch used for electronic door lock " has equally also disclosed the another kind of clutch of similar above structure.
By the analysis to prior art, we can find that clutch conventional in prior art exists same design feature, and described on-of pin only relies on described back-moving spring reset and stretch out described pin-and-hole, and then make lockset keep blocking.
Utility model content
As everyone knows in electric lockset, clutch is the critical component that other linkage components in door handle and lock body carry out power transmission, and as long as described clutch keeps released state, be the outer clutch block of described clutch and interior clutch block in the time relatively rotating in other words slipping state, the rotation of outer handle just can not be delivered to other linkage components in lock body and dead bolt be retracted in lock body and then open lockset by described clutch.And the joint of described clutch or separation are by on-of pin control, for this reason, avoid opening described lockset under abnormal condition, the reliable location of described on-of pin is crucial, in the time of blocking, must ensure that described on-of pin automatically resets and is positioned to make the position of described clutch in released state, for example, leave pin-and-hole mentioned above.And as prior art mentioned above, at present for described on-of pin is automatically reset, conventional technological means is to arrange and can push up the back-moving spring of pressing described on-of pin to reset in clutch.This scheme can make described on-of pin automatically reset and make described clutch separation in theory, but we find that after test of many times this kind of scheme exists fatal drawback, when illegal molecule knocks or clashes into lock body and produce whens vibrations, thereby being shaken, described on-of pin existence produces the mobile possibility that makes clutch unintentional engagement, for example described on-of pin may be entered described clutch hole by vibrations, particularly when described back-moving spring is after long-term use, the elastic reset performance of described back-moving spring will decline, the probability that described in when knocking in this case or clashing into lock body, on-of pin enters described pin-and-hole will improve greatly.And illegal molecule will utilize described return pin to enter just completing and unblank in a flash of described clutch hole.The problems referred to above are very easy to be designed personnel to be ignored, but this structure has seriously reduced the safety of lockset, must manage to solve.
For the deficiencies in the prior art, one of goal of the invention of the present utility model is intended to the reset mode a kind of locate mode in other words by improving described on-of pin, and described on-of pin can reliably be located, thereby improves pick-proof, the crashworthiness of lockset; Secondly, the new interlock mode of a kind of drive unit and on-of pin is provided, thereby can simplifies the structure of described clutch.
For this reason, the utility model proposes a kind of anti-lockset of opening clutch that knocks that has, comprise lock housing body, be contained in clutch and drive unit in described lock housing body, described drive unit is positioned at by described clutch side; Described clutch comprises inside and outside clutch block in relative rotation, and described clutch also has can control the on-of pin that described inside and outside clutch block engages or separates; It is characterized in that, also comprise the intermediate transmission part being arranged between described on-of pin and the output shaft of described drive unit, described intermediate transmission part has curved portions, described intermediate transmission part is not only connected with the output shaft of described drive unit but also is connected with described on-of pin, the output shaft of described drive unit, described on-of pin both one of be slidably connected on described intermediate transmission part along the curved portions of described intermediate transmission part.
Wherein, described lock housing body is the housing of accommodating described clutch, drive unit and other linkage components.
Wherein, the structure of described clutch can adopt numerous embodiments, for example can adopt the structure of clutch conventional in similar prior art, but common ground is described clutch at least has inside and outside clutch block in relative rotation, and control the on-of pin that described inside and outside clutch block engages or separates.Thereby in the time that described on-of pin action engages described inside and outside clutch block, between described inside and outside clutch block, form interaction relation, any clutch block rotates and all can drive another clutch block to rotate, described on-of pin also can rotate thereupon, now, we claim that the residing position of described on-of pin is operating position; Thereby and in the time that described on-of pin reset separates described inside and outside clutch block, the interaction relation of described inside and outside clutch block is eliminated, inside and outside clutch block can only relatively rotate, and now, we claim that the residing position of described on-of pin is home position.According to the function of described on-of pin, can find that described on-of pin at least has two kinds of motions, the first is the telescopic moving on described clutch, the secondth, rotate with described clutch.
In addition, described on-of pin has multiple to the control mode of described clutch, the technical scheme for example disclosing in patent 201020607497.0,200920132323.0, thereby described on-of pin is relatively described clutch to be radially slided and enter described pin-and-hole and make engaging between described inside and outside clutch block, and then described clutch is engaged; Or thereby the relatively described clutch of described on-of pin is done axially-movable top and is pressed one of them clutch block to make described inside and outside clutch block mutually fasten and then make described clutch to engage; The part arm body of described on-of pin is positioned at described clutch for this reason, relatively stretch out described clutch position we can be referred to as outside head.Secondly, in order to distinguish two described clutch blocks, we are calling outer clutch block with the clutch block of outer handle interlock, and calling interior clutch block with the clutch block of Internal handle interlock, " interior " in title, " outward " do not refer to that described clutch block must be the position relationship of inside and outside setting.
And in order to drive described on-of pin action, drive unit being also set in described lock housing body, it is other to produce interlock with described clutch that described drive unit is positioned at described clutch side.Preferably, described drive unit is arranged at the opposite of described clutch, thus the output shaft that makes described drive unit with described on-of pin in relative position.Can shorten in this case the power transfer path between described drive unit and described clutch, make power transmission more stable, structure is compacter.In addition, described drive unit can comprise motor and gear, tooth bar assembly with described motor linkage, can make like this output shaft translational motion of drive unit by described gear, tooth bar assembly.
Wherein, described intermediate transmission part is the power transmission part between described on-of pin and the output shaft of described drive unit, and it can be the individual member that is independent of the output shaft of described on-of pin and described drive unit; Also can be directly with the integrally manufactured moulding of one of the output shaft of described on-of pin or described drive unit or be connected in other way.In addition, described intermediate transmission part is not only connected with the output shaft of described drive unit but also is connected with described on-of pin, the output shaft of described like this drive unit and described on-of pin remain interaction relation, and the output shaft of described drive unit can drive described on-of pin to switch between described home position and described operating position for this reason.Secondly, for the output shaft of described drive unit can fast, stably drive described on-of pin, one end of described intermediate transmission part is preferably located, for example, be positioned the output shaft of described on-of pin, described drive unit or be positioned below by the reference column of mentioning.
Wherein, described intermediate transmission part has curved portions, also allows described on-of pin in the time rotating, can form and being reliably slidably connected of described intermediate transmission part even between described like this on-of pin and described intermediate transmission part be in the situation of sliding connection structure always; Or in the situation that being fixed connection structure between described on-of pin and described intermediate transmission part, in the time that described on-of pin rotates together with described intermediate transmission part, also allow output shaft end combination on described intermediate transmission part of described drive unit slide.
Wherein, the output shaft of described drive unit, described on-of pin both one of be slidably connected on described intermediate transmission part along the curved portions of described intermediate transmission part, refer to the output shaft of described drive unit, described on-of pin both one of be not only slidably connected on described intermediate transmission part, and the direction of sliding is the direction of extending along the curved portions of described intermediate transmission part.Sliding guide mechanism and the detent mechanism of the outside head that like this, in fact described curved portions is exactly described on-of pin or the output shaft of described drive unit; In the time that described on-of pin rotates with described clutch, described intermediate transmission part can not form the obstacle that described on-of pin rotates yet, also not can and the output shaft of described drive unit between form and conflict; In addition, no matter be to form and be slidably connected between described on-of pin and described intermediate transmission part, or form and be slidably connected between described intermediate transmission part and the output shaft of described drive unit, described intermediate transmission part can also be controlled the sliding trace of described on-of pin.Specifically, in the time of locking state, described intermediate transmission part remains on home position described on-of pin to slide; And in the time of released state, described intermediate transmission part remains on operating position described on-of pin to slide.
