Adjustable mirror motor assembly
View Patent ↗An adjustable mirror motor assembly includes a base, a mirror motor component, and a housing. The mirror motor component is fixed on the base and includes a mount and a dragging member. The mount is fixed on the base. A pivot end of the dragging member is pivotally connected to a pivot portion of the mount, and a slide end of the dragging member is slidably disposed in a slide portion of the mount, so that the slide end is pivotally rotated with respect to the pivot end and is slidably moved in the slide portion. A magnet component is on a magnet fixation portion of the dragging member. A mirror is on a mirror fixation portion of the dragging member. The housing covers the base and the mirror motor component.
1 . An adjustable mirror motor assembly adapted for a lens assembly of a mobile device, wherein the adjustable mirror motor assembly comprises:
a base;
a mirror motor component fixed on the base, wherein the mirror motor component comprises:
a mount fixed on the base, wherein the mount has a pivot portion, a slide portion, and a coil fixation portion; the pivot portion and the slide portion are at two opposite ends of the mount, and a plurality of coils are on the coil fixation portion, the coil fixation portion comprises a plurality of fixation regions sequentially arranged on a sliding path of the dragging member, and the coils are respectively fixed on the fixation regions; and
a dragging member having a pivot end, a slide end, a magnet fixation portion, and a mirror fixation portion, wherein the pivot end is pivotally connected to the pivot portion, and the slide end is slidably disposed in the slide portion, so that the slide end is pivotally rotated with respect to the pivot end and is slidably moved in the slide portion; the magnet fixation portion is at a side portion of the dragging member, and a magnet component is on the magnet fixation portion; a mirror is on the mirror fixation portion; and
a housing covering the base and the mirror motor component.
2 . The adjustable mirror motor assembly according to claim 1 , wherein the lens assembly comprises a first lens group, a second lens group, and an optical sensing component, the first lens group, the second lens group, and the optical sensing component are sequentially arranged with each other, and the adjustable mirror motor assembly is disposed between the first lens group and the second lens group.
3 . The adjustable mirror motor assembly according to claim 1 , wherein each of the fixation regions has two fixation posts at two opposite ends thereof, and each of the coils is wound on the two fixation posts of a corresponding one of the fixation regions.
4 . The adjustable mirror motor assembly according to claim 1 , wherein the plurality of coils are flat coils, and the flat coils respectively comprise a plurality of coil patterns sequentially arranged on a sliding path of the dragging member.
5 . The adjustable mirror motor assembly according to claim 1 , wherein the mirror motor component comprises a position sensing element disposed on the mount to determine a position of the dragging member.
