According to the embodiment of the invention, through simple movement stroke detection, when the lens group (comprising the zoom lens group and the zoom lens group) reaches the limit position, the motor is stopped to continue to operate in the same direction, so that abnormal behaviors causing damage to the synchronous focusing lens are avoided.
The lens barrel sliding block comprises a hollow cylindrical barrel, a first sliding groove and a second sliding groove, wherein the first sliding groove and the second sliding groove are arranged on the inner wall of the hollow cylindrical barrel, the first sliding groove is a sliding groove of a zoom lens group, the second sliding groove is a sliding groove of the zoom lens group, and at least one end of the first sliding groove and/or the second sliding groove is provided with a light touch switch, when the light touch switch is touched, the light touch switch sends a touch signal which is used for indicating that the lens barrel sliding block needs to stop rotating and stopping driving the zoom lens group and the zoom lens group to continue moving in the same direction.
Preferably, a first touch switch and a second touch switch are respectively arranged at two ends of the first sliding chute or the second sliding chute, when the first touch switch is touched, the first touch switch sends a first touch signal, and when the second touch switch is touched, the second touch switch sends a second touch signal, wherein the first touch signal indicates that the lens barrel slide block needs to stop driving the zoom lens group and the zoom lens group to continue to move towards the first direction, the second touch signal indicates that the lens barrel slide block needs to stop driving the zoom lens group and the zoom lens group to continue to move towards the second direction, and the first direction is opposite to the second direction. That is, preferably, in the embodiment of the present invention, two tact switches (hereinafter referred to as a first tact switch and a second tact switch) are disposed at two extreme positions (i.e. two ends of a chute) of the chute (hereinafter referred to as a first chute) for controlling the zoom lens set to move, each time the zoom lens set moves to an extreme position, the tact switch is triggered to send a corresponding IO signal to notify the controller to stop operating the motor to continue to operate in the same direction, or directly control the motor to drive the chip to enter the sleep mode, so as to avoid the motor heating or the rapid wear of the gear set and the damage of the lens caused by the motor continuing to operate in the same direction when the lens set reaches the extreme positions. Similarly, the two tact switches may also be installed at two limit positions of a sliding chute (hereinafter referred to as a second sliding chute) of the zoom lens set, and the same effect may also be achieved.
The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.
Taking an example that a first tact switch and a second tact switch are respectively disposed at two ends of a first sliding chute, referring to fig. 1, two ends of a first sliding chute 11 of a lens barrel slider 10 provided in an embodiment of the present invention are respectively provided with a first tact switch 12 and a second tact switch 13, when the first tact switch 12 is touched, the first tact switch 12 sends out a first touch signal, and when the second tact switch 13 is touched, the second tact switch 13 sends out a second touch signal, wherein a dashed frame represents a zoom lens group 14. The specific shape of the variable power lens group 14 is shown in fig. 2.
From another perspective, referring to fig. 3, the protrusion 15 of the zoom lens group 14 is embedded in the first sliding slot 11 of the lens barrel slider 10, the protrusion 15 is higher than the outer surface of the lens barrel slider 10, and the first tactile switch 12 and the second tactile switch 13 are located on the outer surface of the lens barrel slider 10 and located at two end points of the first sliding slot 11, respectively. The protrusion 15 contacts the first tact switch 12 or the second tact switch 13 when moving to the end point of the first sliding chute 11.
Referring to fig. 4, the synchronous focusing lens according to the embodiment of the present invention includes the lens barrel sliding block 20, the zoom lens group 22 disposed on the first sliding slot and the zoom lens group 22 disposed on the second sliding slot of the lens barrel sliding block 20 through the protruding blocks, and the motor module 23, and a lens housing 24 is disposed outside the lens barrel sliding block 20.
Preferably, the motor module 23 includes a motor and a gear set driven by the motor.
That is to say, the synchronous focusing lens includes a lens barrel slider, a zoom lens group and a zoom lens group, wherein the zoom lens group and the zoom lens group are located inside the lens barrel slider. Two convex blocks are arranged on two sides of the zoom lens group, and the two convex blocks are embedded inside a first sliding groove on the lens cone sliding block and limit the movement of the zoom lens group through the first sliding groove. When a motor in the motor module drives the lens barrel slide block to rotate, the first sliding groove is utilized to drive the zoom lens group to move correspondingly. Similarly, two convex blocks are arranged on two sides of the zoom lens group, the two convex blocks are embedded inside a second sliding groove on the lens cone sliding block, and the movement of the zoom lens group is limited through the second sliding groove. When a motor in the motor module drives the gear group to drive the lens barrel slide block to rotate, the second sliding groove is utilized to drive the zoom lens group to move correspondingly.
Referring to fig. 5, the motor module drives the lens barrel slider to rotate under the driving of a driving signal sent by the external motor driving chip, so as to drive the zoom lens group to move along the first sliding groove and drive the zoom lens group to move along the second sliding groove. The two ends of a first sliding groove of a zoom lens group or a second sliding groove of the zoom lens group of the lens barrel sliding block are respectively provided with a first touch switch and a second touch switch, when the first touch switch is touched, the first touch switch sends a first touch signal to the controller, and when the second touch switch is touched, the second touch switch sends a second touch signal to the controller. And after receiving the first touch signal or the second touch signal, the controller sends a corresponding control signal to the motor driving chip, and the motor driving chip sends a corresponding driving signal to the motor module to control the motor module in the synchronous focusing lens to stop driving the lens barrel slide block to rotate and stop driving the zoom lens group and the zoom lens group to continue to move in the same direction.
In addition, the signal that first light touch switch or second light touch switch sent can also send to motor drive chip except sending to the controller as touch signal for motor drive chip gets into the dormant mode, thereby also can play the effect of stopping motor module and continuing the operation.
Similarly, the tact switch can be also arranged on the sliding chute corresponding to the zoom lens group, and the effect of the tact switch is consistent with the effect of the tact switch arranged on the sliding chute corresponding to the zoom lens group.
Referring to fig. 6, as another embodiment, a first tact switch 32 and a second tact switch 33 are respectively disposed at two ends of a second sliding slot 31 of a lens barrel slider 30 provided in the embodiment of the present invention, when the first tact switch 32 is touched, the first tact switch 32 sends a first touch signal, and when the second tact switch 33 is touched, the second tact switch 33 sends a second touch signal, wherein the second sliding slot 31 is a sliding slot of a zoom lens group 34, and the zoom lens group 34 is disposed on the second sliding slot 31 through a bump 35. Another dashed box in fig. 6 represents the zoom lens set 36. The specific shape of the zoom lens group 34 is shown in fig. 7.
Or, a first tact switch may be disposed at one end of the first sliding slot of the lens barrel slider, and a second tact switch may be disposed at the other end of the second sliding slot, so that the effect achieved is the same as the effect achieved by two tact switches disposed at two ends of the same sliding slot, and the zoom lens group move synchronously and in the same amplitude.
Or, only one end of the first sliding chute or the second sliding chute is provided with a tact switch, but at the moment, the lens barrel sliding block can only be controlled to stop rotating, and the zoom lens group are stopped to be driven to move continuously in one direction.
Therefore, in a best mode, the embodiment of the invention is based on the existing lens barrel slide block, and the two ends of the slide groove of the zoom lens group or the zoom lens group are respectively provided with the tact switches, namely the first tact switch and the second tact switch. For example, when the tact switch is disposed in the sliding groove of the variable power lens group, when the variable power lens group moves to the limit positions at the two ends of the first sliding groove, the bump of the variable power lens group may contact the first tact switch or the second tact switch, thereby triggering the first tact switch or the second tact switch to send an IO signal.
The IO signal is a touch signal sent by the first tact switch or the second tact switch received by the controller, for example, specific values thereof include 0 and 1, generally 1 indicates that the bump of the zoom lens group does not contact the tact switch, and 0 indicates that the bump of the zoom lens group contacts the tact switch.
Correspondingly, the image acquisition equipment provided by the embodiment of the invention comprises a controller, a motor driving chip and the synchronous focusing lens; wherein,
when a touch switch in the synchronous focusing lens is touched by a zoom lens group or a convex block of the zoom lens group, a touch signal is sent to the motor driving chip or the controller;

and after receiving the second touch signal, the controller sends a second control signal to the motor driving chip so as to control a motor module in the synchronous focusing lens to stop driving the lens barrel slide block to rotate and stop driving the zoom lens group and the zoom lens group to continuously move towards the second direction.
