Because the inner wall surface of the lens barrel is provided with a plurality of step parts, two adjacent step parts are respectively a first step part and a second step part along the optical axis direction, the first step part is provided with a first surface vertical to the optical axis, the second step part is provided with a second surface vertical to the optical axis, the distance between the first surface and the second surface is L, the thickness of the bearing part attached to the first surface is D, and L is more than D, then when two lenses are respectively arranged on the first surface and the second surface, the distance between the bearing parts of the two lenses is provided, namely, the distance between the optical parts of the two lenses is not determined by the thickness of the bearing part of the lenses, but is determined by the positions of the first surface and the second surface. Therefore, the processing precision of the bearing parts of the lenses does not influence the distance precision of the optical parts of the two adjacent lenses, so that the processing precision requirement of the bearing parts of the lenses can be reduced, the lenses are easier to process, and the production efficiency is improved. In addition, the distance between the optical parts is determined by the step part of the lens barrel, so that the distance precision between the optical parts of two adjacent lenses is improved, and the imaging quality of the optical lens can be improved.

As an alternative implementation manner, in the embodiment of the first aspect of the present invention, at least two adjacent step portions are disposed at intervals in the optical axis direction. In this way, the distance between the first surface and the second surface of the two adjacent step parts can be set to be larger, so that the distance between the optical parts of the lenses attached to the first surface and the second surface is larger, and the distance between the optical parts of the two adjacent lenses can be adjusted.

Since the optical lens barrel adopts the lens barrel as described in the first aspect, the optical distance between two adjacent lenses is determined by the step part of the lens barrel rather than the thickness of the bearing part of the lens, so that the step part of the lens barrel determines the distance between the optical parts, which is beneficial to improving the distance precision between the optical parts of two adjacent lenses, thereby improving the imaging quality of the optical lens. And the processing precision of the bearing parts of the lenses does not influence the distance precision of the optical parts of the two adjacent lenses, so that the processing precision requirement of the bearing parts of the lenses can be reduced, the lenses are easier to process, and the production efficiency is improved.

As an optional implementation manner, in an embodiment of the second aspect of the present invention, the optical lens further includes a light shielding sheet, and the light shielding sheet is attached to the bearing portion, or an accommodating groove is formed in an inner wall surface of the lens barrel to accommodate the light shielding sheet. Through setting up the anti-dazzling screen to stray light diffuse reflection to the imaging surface in the suppression optical lens, and then guarantees the imaging effect, improves optical lens's imaging quality. When the light shielding piece is arranged on the bearing part, one part of the bearing part extends into the attaching space to be attached to the first surface and the third surface, and the other part of the bearing part, which does not extend into the attaching space, is used for being attached to the light shielding piece. Thus, the lens barrel does not need to be provided with a structure for fixing the shading sheet, so that the structure of the lens barrel is simpler. When the optical lens is assembled, the shading sheet can be attached to the bearing part of the lens firstly, and then the lens attached with the shading sheet is sequentially assembled in the lens barrel, so that the optical lens is more convenient to assemble. When the inner wall surface of the lens barrel is provided with the accommodating groove for accommodating the shading sheet, the shading sheet is fixed in the accommodating groove, so that the shading sheet is more firmly fixed.

In a third aspect, the present invention further discloses a camera module, where the camera module includes a photosensitive chip and the optical lens according to the second aspect, and the photosensitive chip is disposed on the image side of the optical lens.

Referring to fig. 1, the optical lens includes a lens barrel 101, a lens 102 installed in the lens barrel 101, a light-shielding sheet 103 and a spacer 104, wherein the lens 102 includes an optical portion 10b and a bearing portion 10a disposed at the periphery of the optical portion 10b, the light-shielding sheet 103 is sandwiched between the bearing portions 10a of the two lenses 102 to suppress stray light in the optical lens from diffusing or reflecting to an imaging surface, and the spacer 104 is sandwiched between the bearing portions 10a of the two lenses 102 to adjust the distance between the optical portions 10b of the two lenses 102, so as to meet the optical performance requirement of the optical lens.

However, the inventors found that the thickness precision and the surface flatness of the bearing portions 10a, the light-shielding sheets 103 and the spacers 104 of the two adjacent lenses 102 affect the distance precision of the optical portions 10b of the two adjacent lenses 102, thereby affecting the imaging quality of the optical lens. If the bearing portion 10a of the lens 102, the light-shielding sheet 103 and the spacer 104 adopt high processing precision, the distance precision between two adjacent optical portions 10b can be improved, but on one hand, the lens 102, the light-shielding sheet 103 and the spacer 104 adopting high processing precision are not easy to process, so that the production efficiency is reduced, on the other hand, even if the lens 102, the light-shielding sheet 103 and the spacer 104 adopting high processing precision are adopted, the processing error still cannot be eliminated, and the distance precision between two adjacent optical portions 10b is poor due to the accumulation of the processing errors of the four components of the two lenses 102, the light-shielding sheet 103 and the spacer 104, so that the higher imaging quality requirement cannot be met.

Therefore, the first embodiment of the utility model discloses an optical lens, which is used for improving the distance precision of optical parts of two adjacent lenses so as to improve the imaging quality of the optical lens.

The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.

Example one

Referring to fig. 2 and 3, the optical lens 100 includes a plurality of lenses 11 and a lens barrel 12, the lenses 11 include an optical portion 111 and a bearing portion 112 disposed on an outer periphery of the optical portion 111, the optical portion 111 is used for light to pass through, and the plurality of lenses 11 are sequentially mounted in the lens barrel 12 along an optical axis o direction.

As shown in fig. 3 to fig. 5, in some embodiments, the inner wall surface of the lens barrel 12 is provided with a plurality of step portions 13, the plurality of step portions 13 are sequentially arranged along the direction of the optical axis o, in the direction from the object side to the image side along the optical axis o, any two adjacent step portions 13 are respectively a first step portion 131 and a second step portion 132, the first step portion 131 has a first surface 13a perpendicular to the optical axis o, the second step portion 132 has a second surface 13b perpendicular to the optical axis o, the first surface 13a and the second surface 13b are respectively used for the abutting portions 112 of the two adjacent lenses 11 to abut against, the distance between the first surface 13a and the second surface 13b is L, the thickness of the abutting portion 112 abutting against the first surface 13a is D, and L > D. Since the plurality of stepped portions 13 are provided on the inner wall surface of the lens barrel 12, the distance between the stepped surfaces of two adjacent stepped portions 13 in the optical axis o direction is L, the thickness of the receiving portion 112 attached to the first surface 13a is D, and L > D, when two lenses 11 are attached to the first surface 13a and the second surface 13b, respectively, the distance between the receiving portions 112 of the two lenses 11, that is, the distance between the optical portions 111 of the two lenses 11 is determined not by the thickness of the receiving portion 112 of the lens 11 but by the positions of the first surface 13a and the second surface 13b, the distance between the optical portions 111 of the two lenses 11. Thus, the machining precision of the bearing parts 112 of the lenses 11 does not affect the distance precision of the optical parts 111 of two adjacent lenses 11, so that the machining precision requirement of the bearing parts 112 of the lenses 11 can be reduced, the lenses 11 are easier to machine, and the production efficiency is improved. In addition, the step part 13 of the lens barrel 12 determines the pitch of the optical parts 111, which is beneficial to improving the precision of the pitch between the optical parts 111 of two adjacent lenses 11, thereby improving the imaging quality of the optical lens 100.

In this embodiment, because two adjacent lenses 11 are attached to the first surface 13a and the second surface 13b of the lens barrel 12, and the thickness of the bearing portion 112 attached to the first surface 13a is smaller than the distance between the first surface 13a and the second surface 13b, when the light-shielding sheet 15 is disposed, the light-shielding sheet 15 can be disposed between the first surface 13a and the second surface 13b, so that the disposition of the light-shielding sheet 15 does not affect the distance accuracy of the optical portions 111 of the lenses 11, thereby improving the distance accuracy of the optical portions 111 of two adjacent lenses 11, and being beneficial to improving the imaging quality of the optical lens 100. In addition, when the lens barrel 12 is adopted, the distance precision of the optical parts 111 of two adjacent lenses 11 is not influenced by the thickness of the light-shielding sheet 15, so that the requirement of the processing precision of the light-shielding sheet 15 can be reduced, and the production efficiency of the light-shielding sheet 15 is favorably improved.

Optionally, the lens barrel 12 may be formed by injection molding, so as to reduce the processing difficulty of the lens barrel 12, and facilitate improving the processing precision of the lens barrel 12, so that when the bearing portion 112 of the lens 11 is attached to the step portion 13 of the lens barrel 12, the position precision of the lens 11 is higher, and the precision of the distance between the optical portions 111 of the two lenses 11 is facilitated to be improved, thereby improving the imaging quality of the optical lens 100.

It can be understood that the lens 11 can be adhered to the step 13 of the lens barrel 12, so as to fix the lens 11 to the lens barrel 12, and prevent the lens 11 from moving relative to the lens barrel 12 to affect the imaging quality.

Optionally, the first step portion 131 further has a third surface 13c, the third surface 13c is connected to the first surface 13a and is parallel to the optical axis o, the third surface 13c and the first surface 13a form an attaching space, the attaching space is used for the support portion 112 to extend into, and the third surface 13c is used for the support portion 112 of the lens 11 to attach and support. Because the bearing portion 112 of the lens 11 extends into the attaching space and is attached to the third surface 13c, that is, the lens 11 can be adhered to two step surfaces of the step portion 13, so as to improve the connection stability between the lens 11 and the lens barrel 12.

As shown in fig. 3 to fig. 5, in some embodiments, the optical lens 100 further includes a light shielding sheet 15, the light shielding sheet 15 is attached to the bearing portion 112, or the inner wall surface of the lens barrel 12 is provided with an accommodating groove 14 for accommodating the light shielding sheet 15. Through setting up light-shielding sheet 15 to stray light diffuse reflection to the imaging surface in the suppression optical lens 100, and then guarantee the imaging effect, improve optical lens 100's imaging quality.

When the light shielding sheet 15 is disposed on the bearing portion 112, a portion of the bearing portion 112 extends into the attachment space to attach to the first surface 13a and the third surface 13c, and another portion of the bearing portion 112, which does not extend into the attachment space, is used for attaching to the light shielding sheet 15. Thus, the lens barrel 12 does not need to be provided with a structure for fixing the light-shielding sheet 15, thereby making the structure of the lens barrel 12 simpler. When assembling the optical lens 100, the light shielding sheet 15 can be attached to the supporting portion 112 of the lens 11, and then the lens 11 with the light shielding sheet 15 attached thereto can be assembled into the lens barrel 12 in sequence, so that the assembly of the optical lens 100 is more convenient.

When the inner wall surface of the lens barrel 12 is provided with the accommodating groove 14 for accommodating the light shielding sheet 15, the light shielding sheet 15 is fixed in the accommodating groove 14, so that the light shielding sheet 15 is more firmly fixed.

Further, the receiving groove 14 is located at one side of the step portion 13 for attaching to the bearing portion 112, and the receiving groove 14 is located outside the attaching space. Since the accommodating groove 14 is located outside the fitting space, when the accommodating groove 14 accommodates the light-shielding sheet 15, the position of the lens 11 is not affected by the arrangement of the light-shielding sheet 15, so that the distance precision between the optical parts 111 of two adjacent lenses 11 is not affected by the thickness precision of the light-shielding sheet 15.

Optionally, the accommodating groove 14 is located at an end of the first surface 13a or the second surface 13b facing the optical axis o, so that the accommodating groove 14 does not overlap with a projection of the attaching space along the optical axis direction, when the optical lens 100 is assembled, the light shielding sheet 15 may be attached to the lens 11 and then assembled into the lens barrel 12, so that the light shielding sheet 15 is accommodated in the accommodating groove 14, and the lens 11 is fixed to the step portion 13, of course, the lens 11 and the light shielding sheet 15 may also be sequentially fixed to the step portion 13 and the accommodating groove 14.

In some embodiments, the depth of the receiving groove 14 is greater than or equal to the thickness of the light shielding sheet 15, and the depth direction of the receiving groove 14 is parallel to the optical axis o direction. Because the depth of the accommodating groove 14 is greater than or equal to the thickness of the light-shielding sheet 15, when the light-shielding sheet 15 is accommodated in the accommodating groove 14, the light-shielding sheet 15 does not protrude relative to the accommodating groove 14, so that the light-shielding sheet 15 does not protrude to the attachment space, and the arrangement of the light-shielding sheet 15 does not affect the position of the lens 11 fixed in the attachment space.

In the related art, in order to increase the distance between the optical portions 111 of two adjacent lenses 11, spacers are further provided, and the spacers are interposed between the bearing portions 112 of the two lenses 11, so as to increase the distance between the optical portions 111, and thus, the thickness accuracy of the spacers affects the distance accuracy between the optical portions 111 of the two adjacent lenses 11.

Based on this, in some embodiments, at least two adjacent step portions 13 are provided at intervals in the optical axis o direction. In this way, the distance between the first surface 13a and the second surface 13b of the two adjacent step portions 13 can be set larger, so that the distance between the optical portions 111 of the lenses 11 attached to the first surface 13a and the second surface 13b is larger. It can be understood that the length of the third surface 13c along the optical axis o direction can be set, so as to adjust the distance between the first step portion 131 and the second step portion 132, so as to meet the distance requirement of the lens 11 mounted on the first step portion 131 and the second step portion 132.

In the optical lens 100 according to the first embodiment of the present invention, since the distance between the first surface 13a and the second surface 13b of the lens barrel 12 is greater than the height of the bearing portion 112 attached to the first surface 13a, when the lenses 11 are assembled in the lens barrel 12, the bearing portions 112 of two adjacent lenses 11 have a distance therebetween, and then the distance between the optical portions 111 of two adjacent lenses 11 is determined by the positions of the first surface 13a and the second surface 13b of the lens barrel 12, that is, the distance accuracy between the optical portions 111 of two adjacent lenses 11 is affected by the processing accuracy of the lens barrel 12 and is not affected by the processing accuracy of two lenses 11, so that the processing accuracy requirement of the lenses 11 is reduced, the distance accuracy between the optical portions 111 of two adjacent lenses 11 is improved, and the imaging quality of the optical lens 100 is improved.
