Referring to fig. 2, Fig. 2 shows the structural schematic diagrams of focus control provided by the utility model.
As shown in Figure 2, focus control may include the Image Sensor 1 set gradually along optical axis, mobile mechanism 2, fix
Mechanism 3 and driving mechanism 4, Image Sensor 1 are fixedly connected on mobile mechanism 2.
Since the mode focused in the related technology is：By camera lens it is whole along optical axis move or camera lens in certain group eyeglass along light
Axis is mobile to be adjusted camera lens and influences at a distance from sensor, and due to realizing the mobile cost that will increase camera lens of camera lens, and frequent
Moving lens the reliability of camera lens will be caused poor, therefore, in the utility model provide a kind of not moving lens and move
The mode of Image Sensor is focused, and is avoided the movement of camera lens, is simplified lens construction, reduces camera lens cost, and
Improve the reliability of camera lens.
Referring to fig. 2, since Image Sensor 1 is fixedly connected on mobile mechanism 2, in order to be sensed by movable image
The mode of device 1 is focused, and the focus control of the utility model further includes the guidance for guiding mobile mechanism 2 to move along optical axis
Mechanism 5.
With continued reference to Fig. 2, mobile mechanism 2 may include leading column 21, dominate the center line and optical axis coincidence of column 21, fixed
Mechanism 3 is provided with leading column sleeve 31 far from the side of mobile mechanism 2, and leading column sleeve 31 is sleeved on leading column 21, due to dominating column
Set 31 is sleeved on leading column 21, and therefore, leading column sleeve 31 is provided with through-hole, and dominating column 21 can be in the through-hole of leading column sleeve 31
It is moved along optical axis.
In order to move leading column 21 in the through-hole of leading column sleeve 31 along optical axis, need to make mobile mechanism 2 along light
Axis is mobile, and in order to move mobile mechanism 2 along optical axis, with continued reference to Fig. 2, it may include auxiliary guide column 51 that guiding mechanism 5, which is arranged,
And auxiliary guide column spring 52, auxiliary guide column spring 52 are sleeved on auxiliary guide column 51, one end of auxiliary guide column 51 passes through fixed machine
