Description

Lens device (2)

The present invention relates to a lens device, and particularly to a lens device for a periscope lens.

A conventional (mobile phone) camera lens, in which a lens device (not shown) for image capture includes a plurality of lens driving modules. In order for the optical components (such as lenses) inside the lens device to operate normally, the relative positional relationship between the lens driving modules must be adjusted during assembly so that the lens driving modules can be moved along the lens device. The center of an imaging unit is arranged axially. Finally, after the relative positional relationship between the lens driving modules is corrected, the lens driving modules are connected through a glue.

Each connection unit 211 sequentially passes through the hole 2012f on the front plate 2012c, the long groove 2032c on the second carrier body 2032, and the hole 2012g on the back plate 2012d. Relative movement between the long groove 2032c and the connecting unit 211 in the first direction X and the second direction Z can be performed, so that the second carrier 203 can be adjusted relative to the second fixing member 201, and its moving range in the first direction X will be because The second carrier body 2032 abuts against the front plate 2012c and the rear plate 2012d of the second fixing piece 201 and is restricted. The movement range in the second direction Z will be because the second carrier body 2032 abuts against the side plate of the second fixing piece 201 2012b or connection unit 211 is restricted. The connecting unit 211 can extend beyond the second fixing member 201 so as to connect with other components (such as the optical path turning unit module).

It is worth noting that by adding the optical path turning unit module, the remaining optical components (such as the lens driving module) provided inside the lens device are no longer restricted to be aligned along the center of the imaging unit. Furthermore, the thickness and the space occupied by the lens device can be reduced. On the other hand, with the combination of the connection unit 211, the corresponding holes 2012f, 2012g, and the long groove 2032c, the lens device of the present invention can avoid a complicated adjustment process during assembly, and can relatively improve its assembly efficiency and reduce its cost. In addition, compared with a structure fixed with glue alone, the connection unit 211 greatly increases the structural strength of the lens device, thereby ensuring quality.
