As shown in fig. 1 to 5, the optical imaging lens includes a lens barrel 10, a lens 20 and a light shielding member 30, an inner wall surface of the lens barrel 10 has a bearing structure 11 extending toward an optical axis 50, the bearing structure 11 includes an object-side bearing surface 111 close to an object side of the lens barrel 10 and an image-side bearing surface 113 close to an image side of the lens barrel 10; a plurality of lenses 20 are arranged at intervals along the axial direction of the lens barrel 10, at least one lens 20 is supported by the object side supporting surface 111, and at least another lens 20 is supported by the image side supporting surface 113; the light shielding members 30 are plural, the plural light shielding members 30 are arranged at intervals along the axial direction of the lens barrel 10, and the light shielding members 30 are located between two adjacent lenses 20.

The inner wall surface of the lens barrel 10 has a bearing structure 11 extending out close to the optical axis 50, so that the pressure transmitted by the lens 20 to the bearing structure 11 is directly applied to the lens barrel 10 during the assembly process, and the structural strength of the bearing structure 11 is ensured. The inner wall of the lens barrel 10 is provided with the bearing structure 11, so that the assembly between the lens 20 of the large-section difference lens and the lens barrel 10 is easier to operate, the assembly between the lens 20 of the large-section difference lens and the lens barrel 10 is further more stable, and the stability of the assembly between the lens 20 of the large-section difference lens and the lens barrel 10 is ensured. At least one lens 20 is supported by the object side supporting surface 111, and at least another lens 20 is supported by the image side supporting surface 113, so that the supporting structure 11 plays a role in supporting and supporting the adjacent lens 20, the lens 20 is prevented from being inclined due to uneven pressure in the assembling process, the assembling of the lens 20 is prevented from being unstable, the assembling stability of the lens 20 is ensured, the imaging quality of the optical imaging lens is ensured, and the system yield is improved. The light shielding piece 30 is located between the two adjacent lenses 20, so that the light shielding piece 30 can bear and protect the two adjacent lenses 20, abrasion between the two adjacent lenses 20 is reduced, the working stability of the optical imaging lens is improved, more stray light can be absorbed simultaneously, and the optical imaging lens can clearly image.

In addition, by arranging the bearing structure 11 on the inner wall of the lens barrel 10, part of the spacer 40 and the light shielding member 30 are omitted, and the cost is saved. Meanwhile, stray light is reduced, and the imaging quality of the optical imaging lens is improved.

The light-shielding member 30 may be a light-shielding paper or a spacer, and may be selected according to actual conditions.

The lens 20 is a plastic lens, and the lens barrel 10 is a plastic barrel.

It should be noted that, the bearing structure 11 and the lens barrel 10 are integrally formed, so that the optical imaging lens is convenient to assemble, and the assembly difficulty is reduced. Meanwhile, the structural strength of the bearing structure 11 is guaranteed, the bearing stability of the lens 20 in the assembling process is improved, and the imaging quality of the optical imaging lens is guaranteed. The bearing structure 11 extends out from the inner wall surface of the lens barrel 10, so that the bearing structure 11 is in seamless connection with the inner wall surface, and the connection tightness between the bearing structure 11 and the inner wall surface is greatly increased. Because the bearing structure 11 and the inner wall surface are integrally formed, the bearing structure 11 cannot shake, the assembly of the lens 20 bearing on the two sides of the bearing structure 11 is more stable, the condition of pressure inclination cannot occur, and the working stability of the optical imaging lens is ensured.

As shown in fig. 1, the lens barrel 10 of the optical imaging lens of the present invention has two assembling directions, one portion of the lenses 20 is assembled at the object side of the lens barrel 10, and is fixed by dispensing at the connection between the lens 20 at the object side and the lens barrel 10 after the assembly is completed, and the other portion of the lenses 20 is assembled at the image side of the lens barrel 10, and is fixed by dispensing at the connection between the lens 20 at the image side and the lens barrel 10 after the assembly is completed.

In fig. 1, a black region at a junction between the lens 20 on the object side and the lens barrel 10 is a dispensing region, and a black region at a junction between the lens 20 on the image side and the lens barrel 10 is a dispensing region.

Example one

As shown in fig. 2, a distance d between the object-side bearing surface 111 and the image-side bearing surface 113 is greater than or equal to 0.2 mm and less than or equal to 2.0 mm. If the distance d between the object-side bearing surface 111 and the image-side bearing surface 113 is smaller than 0.2 mm, the distance between the object-side bearing surface 111 and the image-side bearing surface 113 is too small, so that the structural strength of the bearing structure 11 is weakened, which is not favorable for the stability of the optical imaging lens assembly. Meanwhile, if the distance d between the object-side supporting surface 111 and the image-side supporting surface 113 is smaller than 0.2 mm, the distance between the object-side supporting surface 111 and the image-side supporting surface 113 is too small, and the step difference between the two lenses 20 supported by the object-side supporting surface 111 and the image-side supporting surface 113 is small. If the distance d between the object-side bearing surface 111 and the image-side bearing surface 113 is greater than 2.0 mm, the distance between the object-side bearing surface 111 and the image-side bearing surface 113 is too large, which is not favorable for assembling the lens 20 in the lens barrel 10 and is also unfavorable for miniaturizing the optical imaging lens. The distance d between the object side bearing surface 111 and the image side bearing surface 113 is limited within the range of 0.2 mm to 2.0 mm, which is beneficial to ensuring the structural strength of the bearing structure 11, ensuring the stability of the optical imaging lens assembly and ensuring the reasonability of the optical imaging lens assembly.

As shown in fig. 3, the bearing structure 11 further has a connecting surface 112 connecting the object-side bearing surface 111 and the image-side bearing surface 113, the object-side bearing surface 111 has a groove structure 1111, and the groove structure 1111 is far from the optical axis 50 relative to the connecting surface 112. The arrangement enables the light shielding member 30 to stably bear against the object side bearing surface 111, avoids the risk of the light shielding member 30 inclining during the assembling process, and ensures the assembling precision of the light shielding member 30.

Specifically, the depth h of the groove structure 1111 is greater than or equal to 0.01 mm and less than or equal to 0.05 mm. If the depth h of the groove structure 1111 is smaller than 0.01 mm, the depth of the groove structure 1111 is too small, the groove structure 1111 is not easy to manufacture, and the processing difficulty of the groove structure 1111 is increased. If the depth h of the groove structure 1111 is greater than 0.05 mm, the depth of the groove structure 1111 is too large, which affects the structural strength of the bearing structure 11, and further affects the assembly stability of the optical imaging lens. The depth h of the groove structure 1111 is limited within the range of 0.01 mm to 0.05 mm, so that the structural strength of the bearing structure 11 is guaranteed, and the assembly precision of the optical imaging lens is guaranteed.

Specifically, the width a of the groove bottom of the groove structure 1111 in the direction perpendicular to the optical axis 50 is equal to or greater than 0.01 mm and equal to or less than 0.05 mm. If the width a of the groove bottom of the groove structure 1111 in the direction perpendicular to the optical axis 50 is less than 0.01 mm, the groove structure 1111 is not easy to manufacture, and the processing difficulty of the groove structure 1111 is increased. If the width a of the groove bottom of the groove structure 1111 in the direction perpendicular to the optical axis 50 is greater than 0.05 mm, the bearing area between the light shielding member 30 and the object bearing surface 111 is reduced, which is not favorable for the stability of bearing the light shielding member 30, and affects the assembly accuracy of the light shielding member 30 and the lens barrel 10. The width a of the groove bottom of the groove structure 1111 in the direction perpendicular to the optical axis 50 is limited to be in the range of 0.01 mm to 0.05 mm, which is beneficial to ensuring the stability of the assembly of the light-shielding member 30 and the assembly precision of the light-shielding member 30, so that the light-shielding member 30 is not inclined due to the interference with the lens barrel 10.

As shown in fig. 2, the thickness w1 of the end surface of the object side end of the lens barrel 10 and the thickness w2 of the end surface of the image side end of the lens barrel 10 satisfy: min (w2, w1) is less than or equal to 0.1 mm and less than or equal to 2.0 mm. If the minimum value of the thickness w1 of the end surface of the object side end of the lens barrel 10 and the thickness w2 of the end surface of the image side end of the lens barrel 10 is less than 0.1 mm, the thickness of the lens barrel 10 is too small, which reduces the structural strength of the lens barrel 10, is not favorable for the arrangement of the bearing structure 11, and affects the assembly strength of the optical imaging lens. The minimum value of the thickness w1 of the end surface of the object side end of the lens barrel 10 and the thickness w2 of the end surface of the image side end of the lens barrel 10 is greater than 2.0 mm, so that the thickness of the lens barrel 10 is too large, the lens barrel 10 is thick and heavy, and the thinning of the lens barrel 10 is not facilitated. The minimum value of the thickness w1 of the end surface of the object side end of the lens barrel 10 and the thickness w2 of the end surface of the image side end of the lens barrel 10 is limited to the range of 0.1 mm to 2.0 mm, which is beneficial to ensuring the structural strength of the lens barrel 10 and ensuring the lightness and thinness of the lens barrel 10.

Specifically, the bearing structure 11 is located in the middle of the lens barrel 10, and the large step is located in the middle of the lens barrel 10, so that the assembly between the lens 20 of the large step lens and the lens barrel 10 is easier to operate, the assembly between the lens 20 of the large step lens and the lens barrel 10 is further more stable, and the structural strength between the lens 20 of the large step lens and the lens barrel 10 is ensured. The bearing structure 11 is arranged in the middle of the lens barrel 10, so that when the lens 20 is assembled, the lens can be assembled on two sides of the bearing structure 11, the assembly difficulty is reduced, and the assembly efficiency is increased.

Specifically, when the bearing structure 11 is disposed in the middle of the lens barrel 10, the lens barrel 10 includes a large diameter section 12, a variable diameter section 13, and a small diameter section 14 connected in sequence from the object side to the image side, and the bearing structure 11 is disposed at the variable diameter section 13. The bearing structure 11 is arranged at the variable diameter section 13, so that the risk of shaking of the lens 20 at the variable diameter section 13 in the working process is avoided, and the assembly stability of the lens 20 at the variable diameter section 13 and the lens barrel 10 is ensured. The bearing structure 11 is arranged at the reducing position, so that the bearing structure 11 can bear the lens with large step.

As shown in fig. 1, at least one light shielding member 30 is disposed between the lens 20 and the object bearing surface 111. The arrangement enables the light shielding member 30 to bear and protect the lens 20, avoids the risk that the bearing structure 11 crushes the lens 20, and increases the working stability of the optical imaging lens. Meanwhile, the light shielding member 30 can absorb stray light generated by the bearing structure 11, thereby ensuring that the optical imaging lens can clearly image.

Of course, at least one light shielding member 30 may be disposed between the lens 20 and the image side bearing surface 113. Similar to the effect of disposing the light shielding member 30 between the lens 20 and the object bearing surface 111, the description is omitted here.

Of course, one light-blocking member 30 may be disposed between the lens 20 and the object-side bearing surface 111, and the other light-blocking member 30 may be disposed between the lens 20 and the image-side bearing surface 113, so that stray light can be further absorbed.

As shown in fig. 4, the lens barrel 10 in the present application is integrally molded using a mold. The mold includes a PL bevel in the region where the connecting surface 112 of the bearing structure 11 connects with the image-side bearing surface 113, which is arranged to facilitate demolding of the lens barrel 10. The mold further comprises two insert structures, wherein the first insert structure 70 is located on the object side of the PL slope and connected with the inner wall of the lens barrel 10, and the second insert structure 80 is located on the image side of the PL slope and connected with the inner wall of the lens barrel 10. The mold further comprises two cavities, a first cavity 90 is located at the periphery of the lens barrel 10 and connected with the object side surface of the first sub-structure 70, and a second cavity 100 is located at the periphery of the lens barrel 10 and connected with the image side surface of the second sub-structure 80. The lens barrel 10 is further provided at the periphery thereof with a front mold structure 200 and a rear mold structure 300.

As shown in fig. 1, the optical imaging lens further includes a spacer 40, and the spacer 40 is disposed between adjacent lenses 20, so that the spacer 40 plays a role of bearing and supporting the adjacent lenses 20, and the stability of assembling the lenses 20 in the lens barrel 10 is ensured.

In the embodiment shown in fig. 5, the bearing structure 11 is close to the image side of the lens barrel 10 relative to the object side of the lens barrel 10. At this time, the lens barrel 10 includes a large-diameter section 12 and a small-diameter section 14 connected in sequence from the object side to the image side, and the bearing structure 11 is provided at the small-diameter section 14. The optical imaging lens in this embodiment is a telephoto lens different from that in the first embodiment, and the lens barrel 10 in this embodiment has no variable diameter section 13, and the bearing structure 11 is closer to the image side of the lens barrel 10. The optical imaging lens is convenient to assemble, the assemblage performance of the optical imaging lens can be effectively guaranteed, and the production cost can be effectively saved.
