Description
Technical field
The utility model relates to camera field, particularly relates to a kind of camera dustproof structure.
Background technology
Camera, when structural design, needs to consider the dust-proof of product.Traditional camera is when considering the dustproof design of product, and common way arranges foam in the junction of camera and housing, to prevent dust from entering on imageing sensor or filter, thus reaches dust-proof effect.
Foam is in the process used, constantly extrude for a long time and the deviation occurring size owing to being subject to mechanical part, thus cause sealing place of foam to occur breach, dust is easy to the inside that can enter camera through this breach, arrive on imageing sensor or filter, cause camera imaging to produce spot, have impact on the image quality of image.
Utility model content
The purpose of this utility model overcomes above-mentioned deficiency of the prior art, on the imageing sensor providing a kind of camera not easily to enter into its inside at long process peripheral dust or filter, and dust-proof camera dustproof structure can be stablized in long-time.
The purpose of this utility model is achieved through the following technical solutions:
A kind of camera dustproof structure, comprising: base, shell, magnet, carrier, coil, upper flexure strip, lower flexure strip and terminal;
Described shell is connected with described base and forms a host cavity;
Described magnet is contained in described host cavity;
Described coil is sheathed on described carrier, described upper flexure strip and described lower flexure strip are connected with the two ends of described carrier respectively, the entirety that described carrier, described coil, described upper flexure strip and described lower flexure strip form is contained in described host cavity, described upper flexure strip is connected with described shell, and described lower flexure strip is connected with described base;
Described terminal is arranged in described base and is electrically connected with described lower flexure strip, and described lower flexure strip is electrically connected with described coil;
Described base is provided with the first annular boss, one end of described carrier is provided with the second annular boss, the diameter of described first annular boss is less than the diameter of described second annular boss, described first annular boss is sheathed in described second annular boss, and one end of described second annular boss abuts with described base.
Wherein in an embodiment, the edge of described base has multiple reference column, and multiple described reference column distributes around the central shaft circular array of described base, and the madial wall of multiple described reference column and described shell supports.
Wherein in an embodiment, the quantity of described magnet is multiple, and multiple described magnet is located on described base and around the central shaft circular array of described base and is distributed.
Wherein in an embodiment, described carrier structure in the form of a ring, the inner ring of described carrier offers screw thread.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figure 1, it is the explosive view of the camera dustproof structure 10 of the utility model one embodiment.See also Fig. 2 and Fig. 3, camera dustproof structure 10 comprises: base 100, shell 200, magnet 300, carrier 400, coil 500, upper flexure strip 600, lower flexure strip 700 and terminal 800.
The edge of base 100 has multiple reference column 110, multiple reference column 110 distributes around the central shaft circular array of base 100, shell 200 is connected with base 100, and multiple reference column 110 supports with the madial wall of shell 200, and shell 200 and base 100 form a host cavity 210.
In the present embodiment, the quantity of reference column 110 is four, and the outline of base 100 is square, and reference column 110 is positioned at four end angles of base 100.Be fastened on by shell 200 on base 100, reference column 110 supports with the madial wall of shell 200, thus shell 200 and base 100 better can be fixed, and prevents shell 200 from slippage base 100.
The quantity of magnet 300 is multiple, and multiple magnet 300 is located on base 100, and distributes around the central shaft circular array of base 100.In the present embodiment, the quantity of magnet 300 is four, and four magnet 300 are located on four end angles of base 100 respectively, and are positioned at host cavity 210.
Carrier 400 in the form of a ring, has inner ring and outer ring.Coil 500 is sheathed on the outer ring of carrier 400, and the inner ring of carrier 400 offers screw thread 410, and screw thread 410 is for installing camera.Upper flexure strip 600 and lower flexure strip 700 are connected with the two ends of carrier 400 respectively, the entirety of carrier 400, coil 500, upper flexure strip 600 and lower flexure strip 700 composition is contained in host cavity 210, and upper flexure strip 600 is connected with shell 200, lower flexure strip 700 is connected with base 100.Upper flexure strip 600 and lower flexure strip 700 provide elastic-restoring force to carrier 400.
Please refer to Fig. 4 and Fig. 5, concrete, lower flexure strip 700 offers location hole 710, and one end of carrier 400 is provided with the projection 420 corresponding with location hole 710, and projection 420 is contained in location hole 710.Upper flexure strip 600 offers draw-in groove 610, and one end of carrier 400 is provided with the projection 430 corresponding with draw-in groove 610, and projection 430 is contained in draw-in groove 610.This structure is conducive to the two ends upper flexure strip 600 and lower flexure strip 700 being separately fixed at carrier 400, can prevent carrier 400 from the process of movement, offseting route simultaneously, add the stability of carrier 400 movement.
Refer to Fig. 6, terminal 800 is arranged in base 100 and is electrically connected with lower flexure strip 700, and lower flexure strip 700 is electrically connected with coil 500.
Base 100 is provided with the first circular annular boss 120, and the diameter that one end of carrier 400 is provided with the second circular annular boss 440, first annular boss 120 is less than the diameter of the second annular boss 440.First annular boss 120 is sheathed in the second annular boss 440, and one end of the second annular boss 440 abuts with base 100, forms gap between the first annular boss 120 and the second annular boss 440.
Terminal 800 is energized, and conducts electrical currents to lower flexure strip 700, and lower flexure strip 700 conducts electrical currents to coil 500 again, thus makes coil 500 charged.Because coil 500 is in the magnetic field of magnet 300, the coil 500 of energising is subject to acting in magnetic field of magnetic field force and moves, coil 500 moves and drives the carrier 400 be attached thereto to move, carrier 400 is equiped with camera, the final movement that just can drive camera, thus achieve the focusing of camera.Change the sense of current in coil 500 by terminal 800, the opposite direction that just can realize camera moves.Current vanishes in coil 500, magnetic field force disappears, and carrier 400, under the effect of the elastic-restoring force of upper flexure strip 600 and lower flexure strip 700, drives camera to reset.
Being noted that by arranging the first annular boss 120 on base 100 especially, the second annular boss 440 coordinated is set in one end of carrier 400, and the second annular boss 440 being connected on base 100 simultaneously with the first annular boss 120.Carrier 400 elastic-restoring force that flexure strip 600 and lower flexure strip 700 provide on passing through and reset when, extraneous dust by be difficult to cross the first annular boss 120 and the second dust-proof defence line of annular boss 440 twice simultaneously.Simultaneously; gap is formed between first annular boss 120 and the second annular boss 440; it is inner that dust needs could to arrive camera by the clearance channel of bending; this lessens dust and enter inner possibility; available protecting is installed in inner imageing sensor or filter; prevent camera imaging to produce spot, improve the image quality of image.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
