Description
Technical field
This utility model relates to a kind of camera installation, particularly relates to the dustproof construction of a kind of voice coil motor.
Background technology
Voice coil motor has high frequency sound, high-precision feature.Its cardinal principle is in a permanent-magnetic field, by changing the DC current size of motor interior loop, controls the stretch position of spring leaf, thus drives up and down motion.Mobile phone camera uses VCM to realize automatic focusing function widely, can be regulated the position of camera lens by VCM, presents image clearly.Voice coil motor includes shell, camera lens, upper shell fragment, support, lower shell fragment, lower cover；Described lower cover is fixed on the bottom of shell, has a mesopore allowing camera lens pass in the middle part of lower cover, and camera lens is fixed and is nested with in support and lower end is through the mesopore of lower cover, and support is nested with in the enclosure.The image sensor of camera lens is positioned at the underface of camera lens.Owing to being all socket relation between shell, camera lens, support, during assembling product, camera lens is when loading in support, being threaded connection due between the support that camera lens meeting and plastic material are made, both have collision and burr or dust may fall into and be attached on image sensor under gravity；Meanwhile, in use, owing to camera lens needs focusing thus displacement before and after driving voice coil motor, dust also can fall under cover, then fall into from gap and be attached to image sensor, affect the work of voice coil motor.
Utility model content
The purpose of this utility model is to provide the dustproof construction of the voice coil motor of a kind of good dustproof effect.
For achieving the above object, technical solution of the present utility model is:
This utility model is the dustproof construction of a kind of voice coil motor, including shell, camera lens, upper shell fragment, support, lower shell fragment, lower cover；Described lower cover is fixed on the bottom of shell, there is in the middle part of lower cover a mesopore allowing camera lens pass, camera lens is fixed and is nested with in support and lower end is through the mesopore of lower cover, and support is nested with in the enclosure, the end face of support and bottom surface respectively with the upper shell fragment being nested with in the enclosure and lower shell fragment against；Also including dust-proof glue, this dust-proof glue is arranged on the end face of lower cover and is positioned at outside lower cover mesopore.
Described cradle bottom surface is provided with the annular ring that a circle downwardly extends, and lower cover is provided with a upwardly extending flange collar of circle around the periphery of its mesopore, and this flange collar stretches in the annular ring of cradle bottom surface, is arranged on down the dust-proof glue covered and is positioned at below the annular ring of cradle bottom surface.
Described dust-proof glue coats or is pasted onto down and covers and arrange around lower cover mesopore.
Described lower cover offers multiple arc deep gouge around the periphery of its mesopore, coats or paste one layer of dust-proof glue in this deep gouge.
Described deep gouge is four.
After using such scheme, dust-proof glue is also included due to this utility model, this dust-proof glue is arranged on the end face of lower cover and is positioned at outside lower cover mesopore, this position is placed exactly in the lower section of support, during assembling product, between camera lens and support collision and under gravity burr or dust fall under the dust-proof Jiao Chu that covers, just by dust-proof gluing attached, simultaneously, support is when action, dust and parts burr fall from the lateral gap of support, and just by dust-proof gluing attached, avoid dust and parts burr falls on the surface of image sensor, and the impact on image sensor, good dustproof effect.
Further, owing to lower cover is provided with a upwardly extending flange collar of circle around the periphery of its mesopore, this flange collar stretches in the annular ring of cradle bottom surface, during assembling product, the dust of camera lens and support and support when action, even if fall under the dust that covers and parts burr not by dust-proof gluing live, be also unlikely to the surface at image sensor that can fall, and the impact on image sensor, improve dust-proof effect further.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As Figure 1-Figure 5, being first embodiment of the dustproof construction of a kind of voice coil motor of this utility model, it includes shell 1, camera lens 2, upper shell fragment 3, support 4, lower shell fragment 5, lower cover 6, dust-proof glue 7.
Described lower cover 6 is fixed on the bottom of shell 1, there is in the middle part of lower cover 6 mesopore allowing camera lens pass 61, on lower cover 6 end face, offer four arc deep gouges 62 around the periphery of its mesopore 61, camera lens 2 is fixing to be nested with support 4 in and lower end passes the mesopore of lower cover 6, support 4 is nested with in shell 1, the end face of support 4 and bottom surface respectively with the upper shell fragment 3 being nested with in shell 1 and lower shell fragment 5 against.Being respectively coated with in four deep gouges 62 of described lower cover 6 or paste one layer of dust-proof glue 7, the dust fallen from gap between camera lens 2 and support 4 and parts burr and the dust and the parts burr that fall from the lateral gap of support can be adhered to by this dust-proof glue 7.
As shown in Fig. 6-Fig. 9, it is second embodiment of the dustproof construction of a kind of voice coil motor of this utility model, its structure is essentially identical with first embodiment, except that: the end face of lower cover 6 ' does not offers deep gouge, and dust-proof glue 7 ' coats or is pasted onto on the end face of lower cover 6 ' and arranges around lower cover 6 ' mesopore 61 '.
As shown in Figure 10, it is the 3rd embodiment of the dustproof construction of a kind of voice coil motor of this utility model, its structure is essentially identical with first embodiment, except that: lower cover 6 " around its mesopore 61 " and periphery be provided with a upwardly extending flange collar of circle 62 ", this flange collar 62 " stretch into support 4 " annular ring 41 of bottom surface " in, coating or be pasted onto lower cover 6 " on dust-proof glue 7 " be positioned at support 4 " annular ring 41 of bottom surface " lower section, by support 4 " annular ring 41 " with lower cover 6 " flange collar 62 " and coordinate, can preferably prevent dust from falling into and be arranged on camera lens 2 " lower section image sensor.
In this utility model in the lower cover 6 in first embodiment and second embodiment lower cover 6 ' relative to lower cover 6 in the 3rd embodiment " eliminate upwardly extending flange collar 62 ", thus so that while voice coil motor possesses dust-proof effect, the whole height of voice coil motor is reduced, volume diminishes, and preferably realizes the miniaturization of voice coil motor.
It is the most all to use mechanized equipment to realize continuously to produce due to voice coil motor, in order to preferably realize mechanization, preferably uses the mode of coating to be arranged on the end face of lower cover 6 by dust-proof glue 7.
Emphasis of the present utility model is that and arranges a dust-proof glue.
The above, it is only this utility model preferred embodiment, depending on the installation quantity of dust-proof glue and shape can be according to needs, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
