Two adjacent rectangular lenses 1241: a support frame 1243 supported on a positioning flat plate 1242 of another rectangular lens 1241 is arranged on a positioning flat plate 1242 of at least one rectangular lens 1241, that is, when a plurality of rectangular lenses 1241 are combined into a group 124, a support frame 1243 is arranged on at least one positioning flat plate 1242 of two adjacent positioning flat plates 1242, and the support frame 1243 is supported on another positioning flat plate 1242, thereby realizing the assembly of two adjacent rectangular lenses 1241, which is convenient for assembly and control of the assembly precision, and a matching position does not need to be arranged on the periphery of the rectangular lens 1241, so that the volume of the lens group 124 can be made smaller, and further, a camera using the lens group 124 can also be made smaller.
Referring to fig. 3, two rectangular lenses 1241 are taken as an example: the rectangular lens 1241a and the rectangular lens 1241b are disposed adjacent to each other, a positioning plate 1242a is disposed on the periphery of the rectangular lens 1241a, a positioning plate 1242b is disposed on the periphery of the rectangular lens 1241b, a supporting frame 1243 is disposed on the positioning plate 1242a, the supporting frame 1243 is supported on the positioning plate 1242b, so as to support the rectangular lens 1241a on the rectangular lens 1241b, thereby achieving assembly and connection of the rectangular lens 1241a and the rectangular lens 1241b, and the assembly is convenient. In addition, the supporting frame 1243 is supported on the positioning plate 1242b, and a surface of the supporting frame 1243 close to the positioning plate 1242b is also a plane, so that the supporting frame 1243 can be conveniently processed, and the precision of the supporting frame 1243 can be conveniently controlled.
In one embodiment, the rectangular lenses 1241 of the lens group 124 are connected by laser welding, which can reduce the usage of the lens barrel 1245, and can reduce the volume of the rectangular lenses 1241, so that the lens group 124 can be made smaller.
In one embodiment, two adjacent rectangular lenses 1241 are connected by laser welding, for example, the supporting frame 1243 and the adjacent positioning flat plate 1242 can be connected by laser welding, so that the connection is firm, the deformation is small, and the precision of the combination of two adjacent rectangular lenses 1241 can be well controlled. Of course, in some embodiments, two adjacent rectangular lenses 1241 may be fixed by bonding.
In one embodiment, referring to fig. 3, the light absorbing layer 1244 is disposed on the peripheral side of each positioning plate 1242 and the peripheral side of the supporting frame 1243, so as to prevent external light from entering the lens assembly 124, and further prevent external stray light from affecting, so as to improve the imaging quality.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
