Embodiment
Fig. 2 is according to the utility model embodiment example schematic, and the setting position of dust preventing component is described.As shown in Figure 2, dust preventing component 26 comprises at least one circular element 261 with at least one around property assembly 262.Lens driving apparatus 20 comprises a lens group 21, a camera lens carries seat 22, one upper cover 23, a base 24 and a photosensory assembly 25.Camera lens carries seat 22 in order to accommodating lens group 21, and camera lens carries seat 22 and is connected in base 24 with a plurality of elasticity things (in figure, nothing shows); Upper cover 23 arranges camera lens and carries seat 22 outsides and be fixed on base 24; At least one circular element 261 is arranged at the periphery of lens group 21 with a fine gap (about 0.1mm), at least onely around property assembly 262, at least one circular element 261 is fixed on to base 24; And photosensory assembly 25 arrange lens group 21 under.Camera lens carries seat 22 and can move back and forth with Z direction, reaches the required focusing action of lens group 21.Due to, at least one circular element 261 is arranged at the periphery of lens group 21 with a fine gap, so dust preventing component 26 can't affect the motion of lens group 21.
Wherein, at least one circular element is that a single ring texture, a pair of half range structure or a plurality of width shape structure form, and its material is a kind of material in plastics, metal, compound substance.At least one is some glue or an elastic material around property assembly.
Fig. 3 is for illustrating how dust preventing component reaches dustproof schematic diagram.As shown in Figure 3, when carrying seat 22, camera lens make lens group 21 when Z direction focuses on action, camera lens carries seat 22 can produce spaces 27 with base 21, if can be along space 27 be fallen into by least one circular element 261 and at least one dust preventing component 26 forming around property assembly 262 by 28 of foreign matters.Therefore, at least one circular element 261 with at least one around property assembly 262 effectively blocking foreign body 28 fall into photosensory assembly 25, and then reach dustproof effect.
Wherein, the ultimate range when height of this at least one circular element is equal to or greater than this lens group and moves with Z direction, Z direction is this lens group focusing direction.
Fig. 4 is the schematic top plan view of lens driving apparatus and dust preventing component group.As shown in Figure 4, at least one circular element 261 to be to be arranged at lens group 21 exterior circumferential around coated mode, but still possessing one small is between the two, the outside of at least one circular element 261 utilizes is at least onely fixed on base 24 around property assembly 262.At least one circular element 261 can be implemented by the mode that single ring texture, a pair of half range structure or a plurality of width shape structure form, and wherein this single ring texture is the best example of implementing.Due to the design that is formed in one of, this single ring texture, can avoid structural complexity completely and produce coming off or assembly failure situation, and then cause other problem of product.
In sum, the dust preventing component of lens driving apparatus of the present utility model can effectively prevent dust or any foreign body falls into optical sensor, to reach dustproof object, to avoid photosensory assembly to produce shade in imaging.Separately, dust preventing component is made by elastic material, is arranged at the periphery of lens group, and the protective effect of lens group can be provided simultaneously.
As described above is only the utility model embodiment, when not limiting according to this utility model practical range.The equalization that the utility model claim is done such as changes and modifies, and all should still belong to scope of the present utility model.
