Hole.There is certain interval between light hole and switch base intracavity on switch base, dust is filtering from the gap into rear
When piece switches, it can fall on sensitive chip, switch base intracavity pastes double-side dustproof glue, and dust enters switch base
Behind inner cavity, it is secured on double-side dustproof viscose glue, avoids and fall on sensitive chip.
Further, the inner cavity of the switch base is equipped with the first groove, and double-side dustproof paste adhesive is described first
In groove.Groove plays positioning action to stickup of the double-side dustproof viscose glue on base, prevents that double-side dustproof paste adhesive is askew, leads to
Expose the double-side dustproof viscose glue in via, it is photosensitive to influence sensitive chip, causes to be imaged bad.
Further, the inner cavity of the switch base is equipped with reinforcing rib, and the reinforcing rib forms a square groove,
Its center and the center of light hole are located on same center line, and the left and right sides of the reinforcing rib is equipped with and reinforcing rib is integrated
Pillar, reinforcing rib and the switch base are integrally formed.The development of technology causes electronic product to develop to frivolous direction, equally
Material, switch base wall thickness is thinner, its intensity is lower, and intensity is low, and the easy stress destruction of product or deformation, can influence light
Thread path, influences imaging effect after deformation, in the case where not increasing wall thickness, sets reinforcing rib, adds the strong of whole product
Degree, ensures that the stability of imaging.Pillar and reinforcing rib integrated setting, on the one hand play and strengthen product rigidity, another
Aspect, convenient formation.
Further, screw thread is equipped with the pillar or is melted nut.It is threaded in pillar, passes through bolt or spiral shell
Nail so that switch base is effectively fixedly connected with upper cover.
Further, the inner cavity of the switch base be equipped with outwardly convex the second groove, the switch upper cover with
Corresponding 3rd groove, a chamber resettling is formed between two grooves.It is respectively provided with switch base and switch on lid
It is fluted, the intensity of switch base and upper cover is added, while the chamber resettling formed is easy to placement power set so that cut
Function division is obvious in parallel operation base, ease of assembly.
Further, the optical filter includes full impregnated spectral filtering glass and IR filter glass.Night utilizes full impregnated spectrum
Filter glass can sense the auxiliary light of evening infrared lamp, switch is made full use of all light, so as to substantially increase red
The low of outer video camera shines performance, makes whole picture clear and natural.When daytime, light was abundant, IR filter glass IR cut filters
Piece.
Further, the filter plate carrier is equipped with two optical filter accommodation chambers and strengthens groove.Filter plate carrier exists
Moved under the driving of power set, complete the switching of optical filter, optical filter chamber resettling is arranged on one section of filter plate carrier, separately
One end filter plate carrier is rotated as center of rotation, and stress is easily deformed, and sets groove, neither influences assembling, and can increase filter
The intensity of mating plate carrier, avoids filter plate carrier deformation from causing the assembling of optical filter not in place, causes to be imaged bad.
The beneficial effect that the utility model obtains is：(1) double-side dustproof is sticked on the inner cavity of filter plate carrier and FPC
Glue, forms twice protecting wall to sensitive chip, into the dust of camera lens module, is secured on double-side dustproof viscose glue, is formed anti-
Dirt acts on；(2) manufacturing process is simple and convenient, and it is convenient that double-side dustproof viscose glue is replaced, easy to repair and maintenance.
