Form by above-mentioned member, the action specification of present embodiment is as follows:
At first, after an outside directional current is switched to the first coil C1 and the second coil C2, because electromagnetic induction principle, make the first coil C1 and second coil C2 generation electromagnetic force and form a downward magnetic field, as shown in Figure 8, the camera lens fitted tube 60 of then movable dress group is subjected to the magnetic force guiding, make camera lens fitted tube 60 with the slide assembling part 47 of its slide assembling part 67 downward slippages in electromagnetism dress ring 40, up to first position-arresting part 26 of first position-arresting part, 62 contacts, first framework 20 of camera lens fitted tube 60, promptly camera lens fitted tube 60 is positioned a primary importance.Wherein, the first coil C1 and the formed electromagnetic force of the second coil C2 are greater than the magnetic force of each magnet M1.
On the contrary, as shown in Figure 9, when the first coil C1 and the second coil C2 connect the electric current of opposite course, the first coil C1 and the second coil C2 will form a magnetic field that makes progress, make the 60 upwards slippages of camera lens fitted tube, up to second position-arresting part 36 of second position-arresting part, 63 contacts, second framework 30 of camera lens fitted tube 60, promptly camera lens fitted tube 60 is positioned a second place.
In addition, after activity dress group arrived the location, after promptly movable dress group was positioned at the primary importance or the second place, the first coil C1 and the second coil C2 be conducting electric current no longer just.Because each magnet M1 is the axial middle position that is positioned at electromagnetism dress ring 40, and the magnetic conduction portion 23 of first framework 20 is with respect to the first magnetic conduction portion 52 of camera lens magnetic conductive cylinder 50, and the second magnetic conduction portion 33 of second framework 30 is with respect to the different sizes in the gap of the second magnetic conduction portion 53 of camera lens magnetic conductive cylinder 50, to make each magnet M1 also different corresponding to the magnetic force loop that activity dress group is produced, just wherein the gap of a side is big, then each magnet M1 is also just less at the adsorption magnetic force of this side, so each magnet M1 just can make movable dress group effectively be maintained at the primary importance or the second place.
Therefore, movable dress group only can because of the first coil C1 and the second coil C2 up and down slippage change the position, hence one can see that the utlity model has accurate linearly operating and location.
Moreover, first framework 20 has predetermined slant with the first magnetic conduction portion 52 that the first magnetic conduction portion 23 and the second magnetic conduction portion 33 of second framework 30 all are barb-like and camera lens magnetic conductive cylinder 50 with the second magnetic conduction portion 53 is also corresponding, and can stop that foreign matter enters and has a good dust-proof effect.
Except above explanation, the utility model also can adopt following embodiment:
At first, electromagnetic drive unit can only install a coil just can provide movable dress group to move required electromagnetic force, allows whole production cost reduce.
In addition, each coil and magnet also can not be installed in fixedly in the dress group, are installed in movable dress group and change into, can in like manner reach its action.
The utility model also can not need electromagnetism dress ring, but coil and the direct installing of magnet are fixed in frame set.Wherein, coil and magnet can all be contained in the inside of frame set or all be contained in the outside, perhaps coil and magnet one of them in inside and another one externally.
Certainly, the utility model also can not need load bearing seat and carrying lid, or load bearing seat and carrying lid may be formed in the fuselage that will make up, therefore can directly be installed in the fuselage of application.
Moreover fixedly each first magnetic conduction portion and each second magnetic conduction portion of dress group and movable dress group also can be the mutual corresponding shape of arc, and perhaps other various structures of magnetic force guiding of promoting are all applicable to the utility model.
By the explanation to above embodiment, it is as follows to conclude characteristics of the present utility model:
1, the two all is arranged on fixedly in the dress group the utility model with coil and magnet, or the two all is arranged in the movable dress group, reaching the precision of installing configuration, and improves the various characteristics of action.Camera lens fitted tube electromagnetic drive unit relatively axially back and forth and accurately slippage makes the camera lens focusing have precision.
2, fixedly the magnetic conduction portion of dress group is corresponding to the magnetic conduction portion of activity dress group for the utility model, and it can make magnet effectively activity dress group is positioned fixedly dress group.In addition, each magnetic conduction portion be tiltedly stretch and overhead kick shape and gap less, also can possess good dust-proof, anti-fouling effect.
