Description

Technical Field

[0001] The utility model relates to the technical field of optical equipment, in particular to a lens barrel and a lens. Background Art

[0002] During the design and manufacturing process of lenses, the assembly stability of the lens barrel and lens is one of the key factors affecting the optical performance of the lens. Lenses in existing visual optical systems typically contain one or more lenses housed within a lens barrel. The lens barrel typically supports the lens with a full circle of supporting surfaces, allowing the entire edge of the lens to rest on the supporting surfaces. However, current lens barrels are typically injection molded. Due to process and size limitations, there is a risk of deformation and warping of the lens barrel during the subsequent demolding process. It is also difficult to ensure the parallelism and flatness of the full circle of supporting surfaces, which directly affects the assembly stability of the lens and barrel, and thus the imaging quality of the lens.

[0003] In other words, the lens barrel in the prior art has the problem of poor bearing stability due to process deformation. Utility Model Content

[0004] The main purpose of the utility model is to provide a lens barrel and a lens, so as to solve the problem of poor bearing stability caused by process deformation of the lens barrel in the prior art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a lens barrel is provided, including a supporting ring belt, which is arranged around the circumference of the lens barrel, and a boss structure is provided on the supporting ring belt. The side surface of the boss structure away from the supporting ring belt is a supporting surface. There are multiple boss structures, and the multiple boss structures are arranged at intervals along the circumference of the lens barrel. The radial width B of the boss structure and the axial height h of the boss structure satisfy: 0.67≤B / h≤10.

[0006] Furthermore, the heights of the multiple boss structures on the same supporting ring belt are the same.

[0007] Furthermore, the number of boss structures on the same supporting ring belt is greater than or equal to 2 and less than or equal to 5, and the angle between the line connecting two adjacent boss structures among the multiple boss structures and the optical axis of the lens barrel is greater than or equal to 90° and less than or equal to 120°.

[0008] Furthermore, the supporting annular belt is perpendicular to the optical axis of the lens barrel, and the supporting surface is a plane and perpendicular to the optical axis.

[0009] Furthermore, the distances between the multiple boss structures on the same supporting ring belt and the optical axis of the lens barrel are equal or unequal.

[0010] Furthermore, one side end of the lens barrel has a supporting portion, which has a supporting ring band; and / or the inner wall surface of the lens barrel includes a step surface, which is the supporting ring band.

[0011] Furthermore, the object-side end face or the image-side end face of the lens barrel is a supporting ring belt, and the boss structure on the supporting ring belt expands outwardly in the radial direction.

[0012] Furthermore, the axial height h of the boss structure satisfies: 0.3mm≤h≤1.5mm; and / or the radial width B of the boss structure satisfies: 1mm≤B≤3mm; and / or the length L of the boss structure along the direction perpendicular to the optical axis of the lens barrel satisfies: 3mm≤L≤8mm.

[0013] Furthermore, the projection shape of the boss structure on the supporting ring belt includes one of a rectangle, an ellipse, a semicircle, a triangle and a trapezoid.

[0014] According to another aspect of the present invention, a lens is provided, comprising: a lens, which is one or more lenses; and the lens barrel, wherein the lens is supported against a boss structure of the lens barrel.

[0015] Applying the technical solution of the present utility model, the lens barrel includes a supporting ring belt, which is arranged around the circumference of the lens barrel. A boss structure is provided on the supporting ring belt. The surface of the boss structure on one side away from the supporting ring belt is a supporting surface. There are multiple boss structures, and the multiple boss structures are arranged at intervals along the circumference of the lens barrel. The radial width B of the boss structure and the axial height h of the boss structure satisfy the following relationship: 0.67≤B / h≤10.

[0016] By arranging a plurality of spaced boss structures on the supporting annulus of the lens barrel, the side surface of the boss structure away from the supporting annulus is set as a supporting surface, so that the supporting surfaces arranged at multiple intervals can provide a supporting position for the lens, reducing the supporting area of ​​the lens and the lens barrel, which is conducive to avoiding the influence of the process deformation of the lens barrel on the parallelism and flatness of the supporting surface, making the support of the lens in the lens barrel more stable, and effectively avoiding the risk of the lens tilting or shaking during assembly or use. In addition, the supporting member of the boss structure is arranged in the present application to replace the whole circle support, and it is only necessary to control the parallelism and flatness of the supporting surface of the boss structure, which greatly reduces the production difficulty and cost and improves the molding efficiency.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0035] In order to solve the problem of poor bearing stability caused by process deformation of the lens barrel 10 in the prior art, the present invention provides a lens barrel 10 and a lens.

[0036] like Figures 1 to 12 As shown, the lens barrel 10 includes a supporting ring band 20, which is arranged around the circumference of the lens barrel 10. A boss structure 30 is provided on the supporting ring band 20. The side surface of the boss structure 30 away from the supporting ring band 20 is a supporting surface. There are multiple boss structures 30, and the multiple boss structures 30 are arranged at intervals along the circumference of the lens barrel 10. The radial width B of the boss structure 30 and the axial height h of the boss structure 30 satisfy: 0.67≤B / h≤10.

[0037] By arranging a plurality of spaced boss structures 30 on the supporting annulus 20 of the lens barrel 10, the side surface of the boss structure 30 away from the supporting annulus 20 is set as a supporting surface, so that the supporting surfaces arranged at multiple intervals can provide a supporting position for the lens, reduce the supporting area of ​​the lens and the lens barrel 10, and help avoid the influence of the process deformation of the lens barrel 10 on the parallelism and flatness of the supporting surface, so that the support of the lens in the lens barrel 10 is more stable, and can effectively avoid the risk of the lens tilting or shaking during assembly or use. In addition, the supporting member of the boss structure 30 is arranged in the present application to replace the whole circle support, and only the parallelism and flatness of the supporting surface of the boss structure 30 need to be controlled, which greatly reduces the production difficulty and cost and improves the molding efficiency. By rationally planning the ratio of the radial width B and the axial height h of the boss structure 30 between 0.67 and 10, on the one hand, the structural strength of the boss structure 30 can be guaranteed, which is conducive to ensuring its support strength for the lens, and on the other hand, it can be ensured that the boss structure 30 has enough support area, which is conducive to ensuring the support stability between the lens barrel 10 and the lens.

[0038] In addition, the present application provides multiple boss structures 30 on a supporting ring belt 20, replacing the entire ring supporting ring belt 20. Only the parallelism and flatness of the boss structures 30 need to be controlled, which reduces the reliance on the accuracy of the entire ring supporting ring belt 20. This greatly reduces production costs and improves molding efficiency. At the same time, it reduces the workload of detection points and improves detection efficiency. In different embodiments of the present application, B / h = 0.67, 0.8, 1.7, 2.3, 3.4, 5.8, 7.9, 10.

[0039] In an optional embodiment of the present application, the lens barrel 10 can be provided with one or more supporting annular bands 20 according to actual needs and the number of lenses to be accommodated, and each supporting annular band 20 is provided with a plurality of boss structures 30. The supporting annular band 20 is perpendicular to the optical axis 50 of the lens barrel 10. The supporting annular band 20 is actually a surface for supporting. Such an arrangement makes it possible for the supporting annular band 20 to provide a stable arrangement basis for the boss structure 30, so that the pressure exerted by the lens on the boss structure 30 during subsequent assembly or use can be dispersed to the lens barrel 10 structure where the supporting annular band 20 is located, which is conducive to ensuring the strength and reliability of the boss structure 30. The supporting surface is perpendicular to the optical axis 50. Such an arrangement is conducive to the contact stability between the supporting surface and the lens, and simultaneously enables the boss structure 30 to limit the movement of the lens in the direction of the optical axis 50, thereby ensuring the assembly accuracy of the lens.

[0040] Specifically, the multiple boss structures 30 on the same supporting ring band 20 have the same height. In other words, the surfaces of the multiple boss structures 30 on the same supporting ring band 20, which are away from the supporting ring band 20, are on the same plane, and this plane is perpendicular to the optical axis 50. This arrangement ensures that the multiple boss structures 30 can contact the lens simultaneously, ensuring stable contact between the lens barrel 10 and the lens, avoiding the risk of lens tilt, deviation, or shaking due to height inconsistency, and making the lens support more stable and reliable.

[0041] In practical applications, the boss structures 30 can be set at positions on the supporting annular band 20 that are relatively less prone to deformation. The number of boss structures 30 on the same supporting annular band 20 is greater than or equal to 2 and less than or equal to 5. The angle between the line connecting two adjacent boss structures 30 in the multiple boss structures 30 and the optical axis 50 of the lens barrel 10 is greater than or equal to 90° and less than or equal to 120°. The angles between two adjacent boss structures 30 in the multiple boss structures 30 are equal, so that the distribution of the multiple boss structures 30 on the same supporting annular band 20 is relatively uniform. Preferably, the number of boss structures 30 on the same supporting annular band 20 is 3 or 4. By reasonably constraining the number of boss structures 30 and the angle between adjacent boss structures 30, it is beneficial to ensure the uniformity of the distribution of the boss structures 30, ensure that the number of boss structures 30 is within a reasonable range, and while ensuring that the number of boss structures 30 is sufficient to support the lens, it is possible to ensure the parallelism and flatness of multiple boss structures 30 on the same supporting annulus 20, making the support of the lens more stable and reducing the requirements for the parallelism and flatness of the supporting annulus 20. By constraining the angle between two adjacent boss structures 30 and the optical axis 50 of the lens barrel 10, it is possible to make the distribution of multiple boss structures 30 on the supporting annulus 20 more uniform, which is beneficial to dispersing the support force of the lens, reducing the load of a single boss structure 30, and keeping the distribution of the boss structures 30 relatively symmetrical, so that the support force of multiple boss structures 30 on the lens is more uniform.

[0042] Specifically, the distances between the multiple boss structures 30 on the same supporting annular band 20 and the optical axis 50 of the lens barrel 10 are equal or unequal. That is to say, in an optional embodiment of the present application, when the cross-sectional shape of the lens barrel is a regular circle, the distances between the multiple boss structures 30 on the same supporting annular band 20 and the optical axis 50 of the lens barrel 10 can be equal. In another optional embodiment of the present application, when the cross-sectional shape of the lens barrel is an irregular shape, the distances between the multiple boss structures 30 on the same supporting annular band 20 and the optical axis 50 of the lens barrel 10 can be unequal. Such arrangement can ensure the positional uniformity of the multiple boss structures 30 on the same supporting annular band 20, ensure that the lens can stably bear on these boss structures 30 when installed, avoid the tilt of the lens in the lens barrel 10, ensure that the light in the optical system of the lens can smoothly pass through the lens, and maintain the stability and accuracy of the optical path.

[0043] Specifically, the axial height h of the boss structure 30 satisfies: 0.3mm≤h≤1.5mm; the radial width B of the boss structure 30 satisfies: 1mm≤B≤3mm; and the length L of the boss structure 30 in a direction perpendicular to the optical axis 50 of the lens barrel 10 satisfies: 3mm≤L≤8mm. Specifically, the radial width B and length L of the boss structure 30 are perpendicular to each other and both are perpendicular to the optical axis 50, and the axial height h of the boss structure 30 is parallel to the optical axis 50. It should be noted that the actual size of the boss structure 30 needs to be reasonably planned based on the radial width of the supporting annulus 20 and the supporting area of ​​the lens. By reasonably planning the size of the boss structure 30, it is ensured that the boss structure 30 can provide sufficient supporting area for the lens, making the force applied to the lens more uniform when supporting, reducing stress concentration on the lens, and avoiding the risk of deformation or damage to the lens during assembly or use. At the same time, the size of the boss structure 30 is matched with the size of the lens and the supporting annulus 20 to ensure the reliability of the boss structure 30.

[0044] In addition, by reasonably constraining the size of the boss structure 30, it is possible to provide maximum support for the lens within a limited space, ensuring the assembly stability of the lens and the bearing stability of the boss structure 30, while also facilitating the assembly accuracy of the lens barrel 10. The size of the boss structure 30 can be adjusted according to different lens sizes and bearing requirements, making the design of the lens barrel 10 of the present application more flexible, adaptable to the assembly of a variety of lenses, and enhancing the versatility of the lens barrel 10.

[0045] Specifically, the projection shape of the boss structure 30 on the supporting annular band 20 includes one of a rectangle, an ellipse, a semicircle, a triangle, a waist groove, and a trapezoid. It should be noted that the shape of the boss structure 30 can be selected according to the specific supporting requirements of the lens. By flexibly designing different shapes of the boss structure 30, it can adapt to the supporting requirements of different lenses and various scenarios, ensuring the versatility of the lens barrel 10.

[0046] The present application also provides a lens, comprising a lens and the above-mentioned lens barrel 10, wherein the lens is one or more pieces, and the lens and the boss structure 30 of the lens barrel 10 are supported. The lens can be arranged in the lens barrel 10 and the boss structure 30 in the lens barrel 10, or the lens can also be arranged at the object side end or the image side end of the lens barrel 10 and the boss structure 30 on the object side end face or the image side end face of the lens barrel 10 is supported, and can be arranged according to actual conditions. The lens of the present application can ensure the assembly stability and assembly accuracy of the lens and the lens barrel 10 by adopting the above-mentioned lens barrel 10, so that the flatness or parallelism caused by the deformation of the supporting ring 20 of the lens barrel 10 has less influence on the supporting surface of the boss structure 30, making it easier to ensure the supporting stability of the lens and the boss structure 30, avoiding the poor tilt caused by the deformation of the lens barrel 10, ensuring the assembly accuracy and imaging quality of the lens, and reducing production costs and detection difficulty.

[0047] Example 1

[0048] like Figures 1 to 3 1 , which describes the structure of the lens barrel 10 according to the first embodiment.

[0049] like Figure 2 As shown, one side end of the lens barrel 10 has a supporting portion 40, and the supporting portion 40 extends toward the direction close to the optical axis 50. The supporting portion 40 has a supporting annular band 20. Specifically, the supporting portion 40 toward the side surface inside the lens barrel 10 is the supporting annular band 20. The supporting annular band 20 is provided with a boss structure 30. There are four boss structures 30, and the four boss structures 30 are spaced apart along the circumference of the supporting annular band 20. The angle between the line connecting two adjacent boss structures 30 to the optical axis 50 of the lens barrel 10 is 90 ° or approximately 90 °, which can be arranged according to actual conditions, and the four boss structures 30 are axially symmetrically distributed along the optical axis 50 of the lens barrel 10. Specifically, the line connecting the four boss structures 30 is rectangular. In the present embodiment, the projection shape of the boss structure 30 on the supporting annular band 20 is a waist groove shape or a rectangle. The waist groove shape refers to the shape with a groove in the middle and a wider plane on both sides. The depth and width of the middle groove can be designed according to specific application and demand.

[0050] In this embodiment, the axial height h of the boss structure 30 satisfies the following conditions: 0.3 mm ≤ h ≤ 1.5 mm; the radial width B of the boss structure 30 satisfies the following conditions: 1 mm ≤ B ≤ 3 mm; and the length L of the boss structure 30 in a direction perpendicular to the optical axis 50 of the lens barrel 10 satisfies the following conditions: 3 mm ≤ L ≤ 6 mm. It should be noted that the specific size and shape of the boss structure 30 should be reasonably selected based on the width of the supporting annular zone 20 and the supporting area of ​​the lens.

[0051] It should be noted that the above-mentioned supporting portion 40 can be the object-side supporting portion or the image-side supporting portion of the lens barrel 10. In other words, when the lens barrel 10 has an object-side supporting portion, the object-side supporting portion can be provided with a supporting ring band 20; when the lens barrel 10 has an image-side supporting portion, the image-side supporting portion can be provided with a supporting ring band 20.

[0052] Example 2

[0053] like Figures 4 to 6 As shown in FIG, the structure of the lens barrel 10 of the second embodiment is described.

[0054] like Figure 5 As shown, the inner wall surface of the lens barrel 10 includes a step surface, which is a support ring 20. The step surface is formed by two sections of the lens barrel 10 structure with different inner diameters, and the step surface is formed by the change of the inner diameter of the lens barrel 10. The step surface is located between the object side end and the image side end of the lens barrel 10 and is close to one side end of the lens barrel. It should be noted that Figure 5 In the embodiment, one of the upper and lower sides of the lens barrel is the object side and the other side is the image side, so the upper end face of the lens barrel can be one of the object side end face and the image side end face, and the lower end face of the lens barrel can be the other of the object side end face and the image side end face.

[0055] In this embodiment, there are three boss structures 30, which are spaced apart along the circumference of the supporting annular band 20. The angle between the line connecting two adjacent boss structures 30 and the optical axis 50 of the lens barrel 10 is 120° or approximately 120°, which can be set according to actual conditions. The three boss structures 30 are symmetrically distributed along the optical axis 50 of the lens barrel 10. Specifically, the shape formed by the line connecting the three boss structures 30 is an isosceles triangle.

[0056] In this embodiment, the projection of the boss structure 30 on the supporting annular band 20 is semi-elliptical or semi-circular. The axial height h of the boss structure 30 satisfies the following conditions: 0.3 mm ≤ h ≤ 1.5 mm; the radial width B of the boss structure 30 satisfies the following conditions: 1 mm ≤ B ≤ 3 mm; and the length L of the boss structure 30 in a direction perpendicular to the optical axis 50 of the lens barrel 10 satisfies the following conditions: 3 mm ≤ L ≤ 6 mm. It should be noted that the specific size and shape of the boss structure 30 should be reasonably selected based on the width of the supporting annular band 20 and the supporting area of ​​the lens.

[0057] Optionally, the inner wall surface of the lens barrel 10 may also include multiple stepped surfaces. According to actual needs, the boss structure 30 may be provided on some of the multiple stepped surfaces. The stepped surface where the boss structure 30 is provided may be provided near the object side end of the lens barrel 10, or near the image side end of the lens barrel, or may be located in the middle of the lens barrel 10. That is, in the specific embodiment of the present application, the number of supporting ring belts 20 in the lens barrel 10 may be multiple, which may be determined according to actual supporting needs and assembly methods, and is not limited to the single one shown in the figure.

[0058] Example 3

[0059] like Figures 7 to 9 As shown in FIG, the structure of the lens barrel 10 of the third embodiment is described.

[0060] like Figure 7 and Figure 8 As shown, the inner wall surface of the lens barrel 10 includes a step surface, which serves as a supporting ring belt 20 .

[0061] This embodiment differs from the second embodiment in that the stepped surface provided with the boss structure 30 is located at a different position on the lens barrel 10. The stepped surface is located between the object-side end and the image-side end of the lens barrel 10 and near the center of the lens barrel. Three boss structures 30 are provided on the support annular band 20 and are spaced apart along the circumference of the support annular band 20. The angle between two adjacent boss structures 30 and the optical axis 50 of the lens barrel 10 is 120° or approximately 120°, and can be set according to actual conditions. The three boss structures 30 are symmetrically distributed along the optical axis 50 of the lens barrel 10.

[0062] In this embodiment, the projection shapes of the multiple boss structures 30 on the supporting annular band 20 include rectangles and triangles. Specifically, two of the three boss structures 30 have triangular projection shapes on the supporting annular band 20, and another of the three boss structures 30 has a rectangular projection shape on the supporting annular band 20. The two boss structures 30 with triangular projection shapes are distributed axially symmetrically along the optical axis 50. Specifically, the line connecting the three boss structures 30 forms an isosceles triangle.

[0063] In this embodiment, the axial height h of the rectangular projection structure 30 satisfies the following conditions: 0.3 mm ≤ h ≤ 1.5 mm; the radial width B of the rectangular projection structure 30 satisfies the following conditions: 1 mm ≤ B ≤ 3 mm; and the length L of the rectangular projection structure 30 in a direction perpendicular to the optical axis 50 of the lens barrel 10 satisfies the following conditions: 3 mm ≤ L ≤ 8 mm. The axial height h of the triangular projection structure 30 satisfies the following conditions: 0.3 mm ≤ h ≤ 1.5 mm; the length D of the base of the triangle satisfies the following conditions: 3 mm ≤ D ≤ 8 mm; and the distance H from the vertex to the base of the triangle along the perpendicular bisector satisfies the following conditions: 1 mm ≤ H ≤ 3 mm.

[0064] Example 4

[0065] like Figures 10 to 12 , the structure of the lens barrel 10 according to the fourth embodiment is described.

[0066] like Figure 10As shown, the object side end face or the image side end face of the lens barrel 10 is a supporting ring band 20 , and the boss structure 30 on the supporting ring band 20 extends outward in the radial direction. The outward here actually refers to the outside of the lens barrel 10 .

[0067] In this embodiment, the upper end surface of the lens barrel 10 is a supporting annular band 20, which is the object-side end surface or the image-side end surface. A portion of the boss structure 30 is disposed on the supporting annular band 20, while another portion extends outward in the radial direction, thereby causing the boss structure 30 to partially extend outward relative to the supporting annular band 20. There are three boss structures 30, which are spaced apart along the circumference of the supporting annular band 20. The angle between two adjacent boss structures 30 and the optical axis 50 of the lens barrel 10 is 120° or approximately 120°, which can be set according to actual conditions, and the three boss structures 30 are symmetrically distributed along the optical axis 50 of the lens barrel 10.

[0068] In this embodiment, the projections of the multiple boss structures 30 onto the supporting annular band 20 have rectangular and trapezoidal shapes. Specifically, two of the three boss structures 30 have trapezoidal projections onto the supporting annular band 20, while another of the three boss structures 30 has a rectangular projection onto the supporting annular band 20. Furthermore, the two triangular projections 30 are arranged axially symmetrically. In other words, the line connecting the three boss structures 30 forms an isosceles triangle.

[0069] In this embodiment, the axial height h of the projected rectangular boss structure 30 satisfies the following conditions: 0.3 mm ≤ h ≤ 1.5 mm; the radial width B of the projected rectangular boss structure 30 satisfies the following conditions: 1 mm ≤ B ≤ 3 mm; and the length L of the projected rectangular boss structure 30 in a direction perpendicular to the optical axis 50 of the lens barrel 10 satisfies the following conditions: 3 mm ≤ L ≤ 8 mm. The axial height h of the projected trapezoidal boss structure 30 satisfies the following conditions: 0.3 mm ≤ h ≤ 1.5 mm; the distance H from the upper base to the lower base of the trapezoid satisfies the following conditions: 1 mm ≤ H ≤ 3 mm; and the length D of the lower base of the trapezoid satisfies the following conditions: 3 mm ≤ D ≤ 8 mm.
