The N+1 on any cylindrical surface etc. in facets, the rotation axis of cam body etc. in facets, the idler wheel of the first groove and microswitch
It is engaged by clamping, specifically, the idler wheel of microswitch can roll in cam circumference face, when the roller motion of microswitch is to the
When in one groove, cam can generate Caton, at this point, the part that colour disk exposes electronic lock is single color, and only one
Microswitch is in normally off, and colour disk is exposed to the color of electronic lock and the state relation of microswitch, is convenient for detecting,
Color category on certain colour disk is consistent with the quantity of microswitch, that is, the color on colour disk has N+1 kind, rotates colour disk
Caton sense is able to ascend the operating experience of colour disk.
Further, the first groove 11 runs through cam body 10 along the direction of the rotation axis of cam body 10.
In an embodiment of the present invention, the first groove runs through cam body along the direction of the rotation axis of cam body, micro-
When in the roller motion to the first groove of dynamic switch, prevents from being stopped by the trough rim of the first groove, improve microswitch
Service life, so that cam rotation is more smooth.
Further, the first groove 11 is the first groove of semicolumn, central axis and the cam body 10 of the first groove 11
Rotation axis is parallel.
In an embodiment of the present invention, the first groove is the first groove of semicolumn, the central axis and cam sheet of the first groove
The rotation axis of body is parallel, and when in the roller motion to the first groove of microswitch, idler wheel can be bonded as far as possible with the first groove,
Reduce abrasion of first groove to idler wheel, when idler wheel rolls out the first groove, the first groove will not generate idler wheel biggish
Barrier force is detached from the first groove convenient for idler wheel, so that cam rotation is more smooth.
Further, the side of the first groove 11 and cam body 10 is crossed to form the first trough rim 12 and the second trough rim 13,
First trough rim 12 and the second trough rim 13 are sequentially arranged in the rotation direction of cam body 10, the second trough rim 13 and cam body 10
The distance between rotation axis is greater than the distance between the first trough rim 12 and 10 rotation axis of cam body.
In an embodiment of the present invention, when in the roller motion of microswitch to the first groove, idler wheel is from the second trough rim
Side, which is detached from the first groove counter roller and is detached from the first groove from the first trough rim side, to be more difficult, so that user is in rotation cam,
It is easy rotation cam toward the direction, can be improved the service life of microswitch.
Further, the top surface or bottom surface of cam body 10 are arranged at intervals with N+1 protrusion 20, between adjacent protrusion 20
The second groove 21 is formed, the second groove 21 is arranged in using the rotation axis of cam body 10 as the N+1 on any cylindrical surface of center axis
Etc. in facets.
In an embodiment of the present invention, when the color for adjusting colour disk, the second groove can be sticked by other mechanisms
It is interior, carry out lock cam, prevent cam from rotating, the quantity of the second groove is also N+1, certainly, is scrolled into N in N number of microswitch
It, can be by the second groove come locking cam when a first groove.
Further, the first groove 11 is arranged between adjacent protrusion 20.
In an embodiment of the present invention, the first groove is arranged between adjacent protrusion, can be avoided the first groove and convex
Interference is played, the difficulty of processing of cam is reduced, so that cam structure is more reasonable.
Further, the second groove 21 is greater than the second groove 21 close to convex far from the width of 10 rotation axis side of cam body
Take turns the width of 10 rotation axis side of ontology.
In an embodiment of the present invention, come locking cam position convenient for retaining mechanism and the cooperation of the second groove, improve lock
Tight efficiency.
Further, it is connected between adjacent first groove 11 by cambered surface.
In an embodiment of the present invention, it is rolled on the circumference side of cam convenient for the idler wheel of microswitch, reduces cam
Friction between idler wheel extends the service life of microswitch, meanwhile, so that in rotation cam, it is more smooth, it is promoted
The operating experience of user.
Another embodiment of the invention is, with reference to Fig. 3 and 4, cam rotational position detection device, for detecting cam
The idler wheel 31 of turned position, including N+1 microswitch 30, microswitch 30 is rolled in the circumference side of cam body 10, is appointed
N number of microswitch 30 of anticipating is clamped with N number of first groove 11, is in normally off with the microswitch 30 of the first groove 11 clamping,
Normally open is in the microswitch 30 of the circumference face contact of the cam body 10 between adjacent first groove 11.
In an embodiment of the present invention, when cam rotates, the idler wheel of microswitch is on the circumference side of cam body
It rolls, when there is N number of microswitch to roll to N number of first groove, cam can generate Caton, and cam is rotated by resistance, this
When, the part that colour disk exposes electronic lock is single color, and there are one cam of the microswitch between adjacent first groove
The circumference side of ontology, this microswitch is in normally off, by detecting the signal of this microswitch, can obtain cam
Colour disk is exposed the color of electronic lock and the state relation of microswitch, is convenient for detecting, on certain colour disk by turned position
Color category is consistent with the quantity of microswitch, that is, the color on colour disk has N+1 kind, and the Caton sense for rotating colour disk can mention
Rise the operating experience of colour disk.
Further, the idler wheel of microswitch 30 sticks into the first groove 11, and the rotation axis of microswitch pressing tablet 32 is set
It sets in the same side of the first groove 11 cooperated with microswitch idler wheel 31.
In an embodiment of the present invention, the idler wheel of microswitch sticks into the first groove, the rotation of microswitch pressing tablet
The same side with the first groove of microswitch idler wheel cooperation is arranged in axis, that is, guarantees to rotate when cam along a direction
When, it the pressing tablet of each microswitch or all under tension or is all under pressure, it can be by being arranged on electronic lock shell
Rotation cue button come remind user how rotation cam so that cam can along make pressing tablet under tension direction turn
It is dynamic, improve the service life of microswitch.
Further, the idler wheel 31 of microswitch sticks into the first groove 11, presses on the first groove 11 apart from microswitch
The farther away trough rim of the rotation axis of tabletting 32 and the line of the rotation axis of pressing tablet 32 are pressed on the first groove 11 apart from microswitch
Angle between the tangent line of the farther away trough rim of the rotation axis of tabletting 32 is more than or equal to 90 degree.
In an embodiment of the present invention, it can guarantee that cam can only when the idler wheel of microswitch sticks into the first groove
It is rotated along a direction, and when cam is rotated along this direction, pressing tablet under tension improves making for microswitch
Use the service life.
