Embodiment
In the utility model, the aperture that preceding aperture formula camera lens comprises the mirror cell, is arranged on the eyeglass in the mirror cell and is arranged on eyeglass the place ahead, this aperture is by near the object end.As shown in Figure 4 and Figure 5, mirror cell 101 is combined as a whole by the mode of imbedding ejaculation with aperture 102.Mirror cell 101 comprises cylindric rear portion 107 and convex hoop shape front portion 103.Aperture 102 is arranged in the mirror cell 101, near convex hoop shape front portion 103; Mirror cell 101 forms the aperture section at aperture 102 places, its thickness is identical with the thickness of aperture 102.Be provided with inner chamber 108 in the cylindric rear portion 107, be used to place corresponding optical mirror slip.For fear of light is caused interference, in aperture 102 the place aheads, 101 inside, mirror cell are provided with first chamfering, 104, the first chamferings 104 and extend to mirror cell 101 forward foremost from the aperture section.At aperture 102 rears, 101 inside, mirror cell also are provided with second chamfering, 105, the second chamferings 105 and expand backward from the aperture section, near the eyeglass installation site.
As shown in Figure 6 and Figure 7, the thickness of aperture 102 is 0.029mm, because aperture 102 is to be combined as a whole by mode and the mirror cell 101 that imbeds ejaculation, so the thickness of the aperture section of mirror cell 101 also is 0.029mm.The light of incident can not avoided parasitic light phenomenons such as dazzle, ghost in the reflection of section part generation light.
In order to prevent that aperture 102 from coming off, on the first coniform step 202, aperture fixed leg 203 around be provided with anti-drop structure.This anti-drop structure can be for example to be arranged on aperture fixed leg 203 bothrium 204 on every side.Be provided with some suction holes 205 in bothrium 204, this suction hole 205 is through to the opposite side of fixation side die 201.According to the direction of arrow in as shown in figure 10, air-breathing to the opposite side of fixation side die 201, can make aperture 102 fixing, so can avoid aperture 102 when the mould matched moulds, to come off or touched by the staff and come off.Simultaneously, suction hole 205 also can increase exhaust when the mould matched moulds.
With reference to Figure 11 and Figure 12, the mould of mirror cell 101 also comprises movable side form benevolence 301, and the outer die (not shown) that is looped around fixation side die 201 and movable side form benevolence 301 outsides.Movable side form benevolence 301 comprises large-diameter cylindrical part 302 and minor diameter stylolitic part 303, and the external diameter of large-diameter cylindrical part 302 is identical with the external diameter of fixation side die 201; And the inner chamber 108 that is used to place optical mirror slip in the shape of small diameter portion 303 and length and the mirror cell 101 is suitable.On the small diameter portion 303 of fixation side die 201, be provided with the second coniform step 304, suitable with the shape of second chamfering 105 of mirror cell 101.On the front end face of the second coniform step 304, be provided with groove 305, be used to hold the aperture fixed leg 203 of fixation side die 201.The degree of depth of this groove 305 like this, when both cooperate, and can not produce the slit between the aperture 102 more than or equal to the length of aperture fixed leg 203.
Fixation side die 201 and movable side form benevolence 301 matched moulds, in the middle of the end face of first, second coniform step 202,304 is clamped in aperture 102, and the diameter of these two end faces makes the part of aperture 102 expose all less than the external diameter of aperture 102.Outer die is fixed on the outside, and closely cooperates with fixation side die 201, movable side form benevolence 301.By ejection formation, obtain mirror cell 101, simultaneously aperture 102 is imbedded mirror cell 101, it is as a whole that both are bonded into.
In the utility model, by imbedding the manufacturing process of ejaculation, aperture cross dimensions before dwindling has reduced or eliminated the parasitic light phenomenon that the reflection because of preceding aperture section produces.Because preceding aperture cross dimensions dwindles, therefore increased optical module shared space in the mirror cell, shortened the back focal length of camera lens.On the die of mirror cell, anti-drop structure is set, can avoids aperture when mirror cell's ejection formation, to drop.
