The location sensitive magnetic sheet 4 of location sensitive magnetic sheet 4, the strip extends along 2 direction of motion of moving parts, the fixed cylinder 1
Inner sidewall on be fixed with and opposite with 3 position of the first magnetic patch be used to driving the moving parts 2 front and back fortune in fixed cylinder 1
Dynamic VCM motor coil 5 and the magnetic resistance type for being used to detect 2 position of moving parts opposite with 4 position of location sensitive magnetic sheet
Sensor 6, the VCM motor coil 5 are equipped with the coil slot 51 of front and back direction, and insertion is fixed with the second magnetic in the coil slot 51
Block 7, first magnetic patch 3 is close to that end magnetic pole in 7 direction of the second magnetic patch and second magnetic patch 7 close to first magnetic
That end magnetic pole in 3 direction of block is that there is a natural attraction between the sexes.
A kind of Zoom optic lens of VCM driving as described above, first magnetic patch 3 is two pieces, is symmetricly set on
On the lateral wall of the moving parts 2, the VCM motor coil 5 on the inner sidewall of the fixed cylinder 1 corresponds to two, each VCM
It is all inserted into the coil slot 51 of motor coil 5 and is fixed with the second magnetic patch 7.
A kind of Zoom optic lens of VCM driving as described above are equipped with the guide shaft 8 of front and back direction in the fixed cylinder 1,
The moving parts 2 are slidably mounted on the guide shaft 8.
Compared with prior art, the utility model has the beneficial effects that
It is fixed with the first magnetic patch and VCM motor coil in the fixation medial wall of the tube of this case Zoom optic lens, and exercise group
The second magnetic patch is fixed on part, setting is convenient, and VCM motor coil is not moved with moving parts, and it is convenient to be powered, movement
Setting hot-wire coil is not required on component, movement is convenient, has substantive distinguishing features outstanding and significant progress, first magnetic
Block close to second magnetic patch direction that end magnetic pole and second magnetic patch close to first magnetic patch direction that end magnetic pole
For there is a natural attraction between the sexes, in this way, form magnetic field between them, when moving parts slide back and forth in fixed cylinder, magnetic field position also phase
That answers is moved forward and backward in the fixed cylinder, and such relative motion to be fixed on the VCM motor coil in fixed cylinder and cuts to
Magnetic field, when VCM motor coil is powered, the first magnetic patch drives the relatively fixed cylinder forward slip of the moving parts or slides backward
To consume energy, when change flows through the current direction of VCM motor coil, moving parts also change the direction of motion accordingly；In addition,
This case passes through the setting of location sensitive magnetic sheet and magnetic resistance type sensor, is easy to implement the accurate inspection to the moving parts position
It surveys and closed loop is adjusted, be conducive to the position for adjusting the moving parts as needed and accurately.

Fig. 1 is the perspective view of this case.
Fig. 2 is one of explosion diagram of this case.
Fig. 3 is the two of the explosion diagram of this case.
Specific embodiment
The utility model feature and other correlated characteristics are described in further detail by the following examples, in order to same
The understanding of industry technology personnel:
As shown in Figure 1 to Figure 3, a kind of Zoom optic lens of VCM driving, it is characterised in that it include fixed cylinder 1, it is described
The moving parts 2 that can be slid back and forth in fixed cylinder 1 are slidably connected in fixed cylinder 1, on the lateral wall of the moving parts 2
It is fixed with the location sensitive magnetic sheet 4 of the first magnetic patch 3 and strip, the location sensitive magnetic sheet 4 of the strip is along the moving parts 2
The direction of motion extends, and is fixed on the inner sidewall of the fixed cylinder 1 and opposite with 3 position of the first magnetic patch is used to drive the fortune
