Abstract
The utility model discloses a kind of improvement structures of voice coil motor bracket；It is made of rack body and sealing ring；The rack body has the mesoporous of fixed lens, and two or more card slots are opened up on the side wall of mesoporous；The outer wall of the sealing ring has two or more the convex blocks extended radially outward, and sealing ring is nested with the convex block holding in the mesoporous of rack body and on sealing ring in the card slot of rack body.Since the sealing ring of the utility model passes through convex block holding in the card slot of rack body, it is made to be not easy to disengage, this design has lacked this processing procedure of assembling dispensing compared to former design, can reduce cost.Moreover, the utility model is by double-shot moulding technology, by rack body and sealing ring in same set of mold injection molding, production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of voice coil motors, more particularly to a kind of improvement structure of voice coil motor bracket.
Background technique
Voice coil motor has the characteristics that high frequency sound, high-precision.Its cardinal principle is to pass through change in a permanent-magnetic field
The DC current size of motor interior loop, to control the stretch position of spring leaf, so that camera lens be driven to move up and down.Such as Figure 1A institute
Show, in voice coil motor, bracket 1 ' is the component for fixed lens 2 ', and sealing ring is equipped between bracket 1 ' and camera lens 2 '
3 ', in traditional design, two components of bracket 1 ' and sealing ring 3 ' are to separate molding, then sealing ring 3 ' is nested in bracket 1 '
In hole 11 ', then bonded together by glue sealing circle 3 ' with 1 ' mesoporous 11 ' of bracket.The traditional structure is more to install together
The process of sealing ring.
Summary of the invention
The purpose of this utility model is to provide a kind of improvement structures for assembling efficiently voice coil motor bracket.
To achieve the above object, the technical solution of the utility model is:
The utility model is a kind of improvement structure of voice coil motor bracket；It is made of rack body and sealing ring；Described
Rack body has the mesoporous of fixed lens, and two or more card slots are opened up on the side wall of mesoporous；Outside the sealing ring
Wall has two or more the convex blocks extended radially outward, and sealing ring is nested with convex in the mesoporous of rack body and on sealing ring
Block holding is in the card slot of rack body.
The rack body and sealing ring is by double-shot moulding technology, by two components in same set of mold injection
Molding.
After adopting the above scheme, it is made of due to the utility model rack body and sealing ring, sealing ring passes through convex block card
It sets in the card slot of rack body, it is made to be not easy to disengage, this design has lacked this processing procedure of assembling dispensing compared to former design, can drop
Low cost.Moreover, the utility model passes through double-shot moulding technology, by rack body and sealing ring in same set of mold injection
Molding, production efficiency greatly improve.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Detailed description of the invention
Figure 1A is the cooperation schematic diagram of bracket and camera lens in existing voice coil motor；
Fig. 1 is the stereogram exploded view of the utility model；
Fig. 2 is the main view of the utility model；
Fig. 3 is cross-sectional view of the Fig. 2 along line A-A.
Specific embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of improvement structure of voice coil motor bracket；By rack body 1 and close
Seal 2 forms.
The rack body 1 has the mesoporous 11 of fixed lens 10, and two or more are opened up on the side wall of mesoporous 11
Card slot 12；The outer wall of the sealing ring 2 has two or more the convex blocks 21 extended radially outward, and sealing ring 2, which is nested with, to be propped up
21 holding of convex block in the mesoporous 11 of frame ontology 1 and on sealing ring 2 is in the card slot 12 of rack body 1.
The rack body 1 and sealing ring 2 is infused two components in same mold by double-shot moulding technology
It is moulded into type.
The assembly method of the utility model:
Camera lens 10 is nested in a manner of interference or transition fit in the mesoporous 11 of rack body 1 and close with sealing ring 2
Cooperation.
The above, only the utility model preferred embodiment, rack body pocket numbers and sealing ring upper protruding block
Quantity can be according to needs depending on, therefore cannot be limited with this utility model implementation range, i.e., according to present utility model application patent
Equivalent changes and modifications made by range and description should still belong in the range of the utility model patent covers.
