Embodiment
The embodiments of the invention provide a kind of lens barrel sliding block, synchronizing focus camera lens, image capture device, controller and its control
Method processed.
The embodiment of the present invention is detected by simple movement travel, works as lens group（Including zoom lens set and focus-variable lens
Group）When reaching the limit of position, stopping motor continuation is equidirectional to remain in operation, so that avoiding the occurrence of causes synchronizing focus camera lens to damage
Abnormal behaviour.
A kind of lens barrel sliding block provided in an embodiment of the present invention, including hollow circuit cylinder cylinder, are arranged on hollow circuit cylinder cylinder inwall
The first chute and the second chute, wherein, the first chute be zoom lens set chute, the second chute be focus-variable lens group cunning
Groove, touch-switch is provided with least one end of the first chute and/or the second chute, wherein when the touch-switch is touched
When, the touch-switch is sent for indicating that the lens barrel sliding block needs to stop operating, and stops driving zoom lens set and zoom
Lens set is to the equidirectional touching signals continued to move to.
Touched out it is preferred that being respectively arranged with the first touch-switch and second at the two ends of the first chute or the second chute
Close, when first touch-switch is touched, first touch-switch sends the first touching signals, touch when described second
When switch is touched, second touch-switch sends the second touching signals, wherein, the first touching signals indicate that the lens barrel is slided
Block needs to stop driving zoom lens set and focus-variable lens group to continue to move to first direction, and the second touching signals indicate the mirror
Cylinder sliding block needs to stop driving zoom lens set and focus-variable lens group to continue to move to second direction, first direction and second direction
Conversely.That is, preferably, the embodiment of the present invention passes through the chute in control zoom lens set movement（Hereinafter referred to as first
Chute）Two extreme positions（That is chute two ends）Dispose two touch-switch（Hereinafter referred to as the first touch-switch and second light
Touch switch）, each zoom lens set is moved to extreme position and just triggers touch-switch, sends corresponding I/O signal, to notify control
Device processed stops operation motor and continues equidirectional operating, or directly controlled motor driving chip enters park mode, it is to avoid work as mirror
When head group reaches the limit of position, the motor feels hot caused by motor continues to equidirectional remain in operation or the Fast Wearing of gear train
And the damage of camera lens.Similarly, the two touch-switch can also be arranged on the chute of focus-variable lens group（Hereinafter referred to as second slides
Groove）Two extreme positions, same effect can also be reached.
Technical scheme provided in an embodiment of the present invention is described below in conjunction with the accompanying drawings.
So that the first touch-switch and the second touch-switch are separately positioned on the first chute two ends as an example, referring to Fig. 1, the present invention
The two ends of first chute 11 of the lens barrel sliding block 10 that embodiment is provided are respectively arranged with the first touch-switch 12 and second and touched out
13 are closed, when first touch-switch 12 is touched, first touch-switch 12 sends the first touching signals, when described the
When two touch-switch 13 are touched, second touch-switch 13 sends the second touching signals, and dotted line frame therein represents zoom
Lens set 14.The concrete shape of zoom lens set 14 is referring to Fig. 2.
In terms of another angle, referring to Fig. 3, the projection 15 of zoom lens set 14 is embedded in the first chute of lens barrel sliding block 10
In 11, projection 15 is higher by the outer surface of lens barrel sliding block 10, and the first touch-switch 12 and the second touch-switch 13 are located at lens barrel sliding block 10
Outer surface, and respectively at two end points of the first chute 11.Projection 15 can connect when moving to the end points of the first chute 11
Contact the first touch-switch 12 or the second touch-switch 13.
Referring to Fig. 4, a kind of synchronizing focus camera lens provided in an embodiment of the present invention, including described lens barrel sliding block 20, pass through
