One position, control precision is low, the bad phenomenons such as step-out easily occurs；
Zoom optic lens stability currently on the market is poor, big by magnetic field and noise effect, and energy consumption is high, easily grinds
The wild effects such as damage, step-out；VCM motor driving trip simultaneously in the market is short, and structure is short and small；Present customer is unable to satisfy to get over
Carry out more strict requirements.
In addition, in Zoom optic lens the driving structure of traditional VCM motor mainly one by one coil in one block of U-shaped magnet
Permanent-magnetic field internal cutting magnetic induction line, convert electrical energy into mechanical energy, the setting of U-shaped magnet is inconvenient, and coil is arranged
Also be inconvenient to be powered on moving parts.
Therefore, how to overcome above-mentioned defect, it has also become those skilled in the art's important topic urgently to be resolved.
Summary of the invention
The invention overcomes the shortcomings of the above-mentioned technology and provides a kind of Zoom optic lens driven using VCM.
To achieve the above object, present invention employs following technical proposals:
A kind of Zoom optic lens driven using VCM, are included fixed cylinder 1, slidably connect energy in the fixed cylinder 1
The moving parts 2 slid back and forth in fixed cylinder 1 are reached, are fixed with the first magnetic patch 3 and strip on the lateral wall of the moving parts 2
The location sensitive magnetic sheet 4 of the location sensitive magnetic sheet 4 of shape, the strip extends along 2 direction of motion of moving parts, the fixation
Cylinder 1 inner sidewall on be fixed with it is opposite with 3 position of the first magnetic patch be used to drive the moving parts 2 in fixed cylinder 1 before
The VCM motor coil 5 and the magnetoelectricity for being used to detect 2 position of moving parts opposite with 4 position of location sensitive magnetic sheet moved afterwards
Resistive 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 in the coil slot 51
Two magnetic patch 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 described the
That end magnetic pole in one magnetic patch, 3 direction is that there is a natural attraction between the sexes.
A kind of Zoom optic lens driven using VCM as described above, first magnetic patch 3 are two pieces, are symmetrically set
It sets 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, often
It is all inserted into the coil slot 51 of a VCM motor coil 5 and is fixed with the second magnetic patch 7.
A kind of Zoom optic lens driven using VCM as described above are equipped with leading for front and back direction in the fixed cylinder 1
Axis 8, the moving parts 2 are slidably mounted on the guide shaft 8.
Compared with prior art, the beneficial effects of the present invention are:
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.
Detailed description of the invention
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
Feature of present invention and other correlated characteristics are described in further detail by the following examples, in order to the same industry
The understanding of technical staff:
As shown in Figure 1 to Figure 3, a kind of Zoom optic lens driven using VCM, it is characterised in that it include fixed cylinder 1,
The moving parts 2 that can be slid back and forth in fixed cylinder 1, the outside of the moving parts 2 are slidably connected in the fixed cylinder 1
The location sensitive magnetic sheet 4 of the first magnetic patch 3 and strip is fixed on wall, the location sensitive magnetic sheet 4 of the strip is moved along described
2 direction of motion of component 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 VCM motor coil 5 and use opposite with 4 position of location sensitive magnetic sheet that the moving parts 2 move forward and backward in fixed cylinder 1
Magnetic resistance type sensor 6 in detection 2 position of moving parts, the VCM motor coil 5 are equipped with the coil slot 51 of front and back direction,
Insertion is fixed with the second magnetic patch 7, that end magnetic of first magnetic patch 3 close to 7 direction of the second magnetic patch in the coil slot 51
