Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1, in the related art, a lens 10 includes a lens barrel 101 and a plurality of (two or more than two) lenses 102, the lens barrel 101 has an accommodating cavity 1011, each lens 102 is located in the accommodating cavity 1011 of the lens barrel 101, and an outer side surface of each lens 102 is attached to an inner peripheral surface of the lens 10. In order to satisfy the optical distance between two adjacent lenses 102, a certain distance is provided between two adjacent lenses 102 according to the design requirement, and a spacer ring 103 for adjusting the height of the lens 102 is usually added between two adjacent lenses 102 after the spacing, and two end surfaces of the spacer ring 103 close to the object side and the image side are respectively used for bearing the lenses 102 on two sides thereof, so as to enhance the connection stability between the lens 102 and the lens barrel 101.

In order to prevent stray light from passing through the optical effective area of the lens 102 and affecting the imaging quality, a light shielding sheet 104 for shielding stray light is usually added on the end surface near the outer side and the end surface near the image side of the spacer ring 103 to ensure the optical performance of the lens 10. Since the position of the light-shielding sheet 104 relative to the spacer ring 103 is relatively fixed (i.e. the light-shielding sheet 104 is located on the object-side end surface and the image-side end surface of the spacer ring 103) and is limited by the position of the adjacent lens 102, the optical performance of the lens 10 is affected.

In order to solve the above technical problems, referring to fig. 3 to 5, a first aspect of the present application provides a spacer assembly 100, the spacer assembly 100 is used for spacing two lenses adjacently disposed in a lens, and includes a spacer ring 110, a light-shielding sheet 120 and a connecting member 130, one end of the connecting member 130 is connected to the second peripheral wall 122 of the light-shielding sheet 120, and the other end is embedded in the spacer ring 110, and the position of the connecting member 130 embedded in the spacer ring 110 can be changed according to design requirements to reasonably adjust the position of the light-shielding sheet 120 relative to the spacer ring 110 so as to improve the optical performance of the lens.

Referring to fig. 5, the spacer assembly 100 includes a spacer ring 110, a light shielding sheet 120 and a connecting member 130.

The spacer ring 110 serves as a bearing member between two adjacent lenses, and may be made of a transparent material or a non-transparent material, such as a resin material. Considering that the spacer ring 110 needs to be capable of blocking light rays (e.g., light rays passing through the non-optically effective area portion of the lens) which are incident from the light inlet of the lens to the inside of the lens barrel and irradiate to a position close to the edge, in addition to two adjacent lenses, that is, the spacer ring 110 is capable of reflecting or absorbing stray light, when the spacer ring 110 is made of a light-transmitting material (e.g., transparent resin), a light-shielding layer may be provided on the entire exposed surface of the spacer ring 110, the light-shielding layer having a good light-absorbing effect, which can absorb the ineffective light rays emitted into the inner edge of the lens cone, the light shielding layer can be a black ink layer or a carbon powder particle layer, for example, when the light-shielding layer is a black ink layer, the entire exposed surface of the spacer ring 110 can be covered by spraying, when the light shielding layer is a carbon powder particle layer, the exposed surface of the whole spacing ring 110 can be covered by adopting an adhesive mode. In this embodiment, the spacer ring 110 has a first inner peripheral wall surface 111, a first through hole 1111 is formed by surrounding the first inner peripheral wall surface 111, the effective light beam formed by processing the light beam entering from the light inlet of the lens by the optical effective area portion of the lens can pass through the first through hole 1111 of the spacer ring 110 and be irradiated onto the object side surface of the next lens, and the ineffective light beam formed by processing the light beam entering from the light inlet of the lens by the non-optical effective area portion of the lens is irradiated onto the light shielding layer on the object side wall surface of the spacer ring 110 and is absorbed. It should be noted that the material of the spacer ring 110 is not limited herein, and the designer can select a suitable material according to the actual requirement as long as the spacer ring 110 can perform the bearing function on the lens and simultaneously has a good light absorption function.

The light-shielding sheet 120 serves as a member for shielding and reflecting stray light in light incident from the light-incident port of the lens to the inside of the lens barrel, that is, the light-shielding sheet 120 can reflect or absorb stray light, which can be understood as light causing blurring of an image formed by an optical system of the lens, and the light-shielding sheet 120 can be made of a light-transmitting material or a non-light-transmitting material, for example, when the light-shielding sheet 120 is made of a light-transmitting material, the light-transmitting material can be transparent resin, and when the light-shielding sheet 120 is made of a non-light-transmitting material, the material can be black resin or metal. Of course, no matter what kind of material is used for the light-shielding sheet 120, in order to ensure that the light-shielding sheet 120 has a good absorption effect on stray light, the surface of the light-shielding sheet 120 may be treated to increase the surface roughness of the light-shielding sheet 120, and a light-shielding layer may also be added on the light-shielding sheet 120, wherein the light-shielding layer has a good absorption effect on light, which can be used to further absorb stray light and enhance the extinction effect, for example, the light-shielding layer may be disposed on a side surface of the light-shielding sheet 120 facing the object side, in this embodiment, the light-shielding layer is disposed on the entire outer surface of the light-shielding sheet 120, that is, each surface of the light-shielding sheet 120 can absorb stray light, and further improves the extinction performance of the light-shielding. It should be noted that the light-shielding layer and the light-shielding layer disposed on the exposed surface of the spacer ring 110 may be made of the same light-shielding material, and the description thereof is omitted. In the present embodiment, the light-shielding sheet 120 has a second inner peripheral wall surface 121 and a second outer peripheral wall surface 122 disposed around the second inner peripheral wall surface 121, and the second inner peripheral wall surface 121 surrounds and forms the second through hole 1211, that is, the light-shielding sheet 120 is annular, the second inner peripheral wall surface 121 of the light-shielding sheet 120 corresponds to an inner annular surface of the annular light-shielding sheet 120, and the second outer peripheral wall surface 122 of the light-shielding sheet 120 corresponds to an outer annular surface of the annular light-shielding sheet 120.

Referring to fig. 4 to 5, the connecting member 130 serves as a member for connecting the light shielding sheet 120 to the spacer ring 110, and the material of the connecting member 130 is not limited, and a designer may select a suitable material in consideration of the rigidity and strength of the material. In the present embodiment, the connecting member 130 is connected to the second outer peripheral wall surface 122 of the light shielding sheet 120, and the connecting member 130 is embedded in the spacing ring 110 so that the light shielding sheet 120 is located in the first through hole 1111 of the spacing ring 110, that is, the annular light shielding sheet 120 is sleeved in the first through hole 1111 of the spacing ring 110 through the connecting member 130. It can be understood that the requirement of the optical lens for the light-passing hole can be satisfied by changing the position of the second through hole 1211 of the light-shielding sheet 120 and the radial dimension of the second through hole 1211 to enhance the optical performance of the lens, that is, the light-shielding sheet 120 changes the relative position between the light-shielding sheet 120 and the spacer ring 110 by changing the position of the connecting member 130 embedded in the spacer ring 110, so as to adjust the position of the second through hole 1211 of the light-shielding sheet 120 to satisfy the requirement of the optical lens for the light-passing hole to enhance the optical performance of the lens, and for convenience of description and understanding of the position of the light-shielding sheet 120 relative to the spacer ring 110, a "height position dimension N" of the light-shielding sheet 120 and an "inner diameter dimension M" of the light-shielding sheet 120 are defined, wherein the "height position dimension N" of the light-shielding sheet 120 indicates that the image side wall surface (the end surface facing away from the object side or the light-shielding sheet 120) of the light-shielding sheet 120 and the image side of the spacer ring 110 are along The distance between the side wall surfaces (the end surface of the spacer ring 110 facing away from the object side or the end surface facing the image side), "the inner diameter dimension M" of the light-shielding sheet 120 represents the aperture size of the second through hole 1211 of the light-shielding sheet 120 in a cross section passing through the light-shielding sheet 120 in a direction perpendicular to the hole axis of the first through hole 1111 or the second through hole 1211, in the present embodiment, the end surface of the light-shielding sheet 120 close to the object side and the end surface of the spacer ring 110 close to the object side are spaced apart in the hole axis direction of the first through hole 1111, and the end surface of the light-shielding sheet 120 close to the image side and the end surface of the spacer ring 110 close to the image side are spaced apart in the hole axis direction of the first through hole 1111, that is, after the connector 130 is inserted into the spacer ring 110, the light-shielding sheet 120 is not located on the wall surface of the spacer ring 110 close to the object side or on the wall surface of the spacer ring 110 close to the image side, that is N ≠ 0, and the height position dimension N of the The thickness dimension in the direction.

In order to further improve the optical performance of the lens, in the present embodiment, after the light-shielding plate 120 is mounted on the spacer ring 110 through the connecting member 130, the hole axis of the second through hole 1211 of the light-shielding plate 120 coincides with the hole axis of the first through hole 1111 of the spacer ring 110.

In summary, the designer can change the position of the connecting member 130 embedded in the spacer ring 110 according to actual requirements to change the height position dimension N of the light-shielding sheet 120 relative to the spacer ring 110 in the direction parallel to the hole axis of the first through hole 1111 or the second through hole 1211 and change the inner diameter dimension M of the light-shielding sheet 120 relative to the spacer ring 110 in the cross section passing through the hole axis perpendicular to the first through hole 1111 or the second through hole 1211, that is, change the position of the connecting member 130 embedded in the spacer ring 110 to change the relative position between the light-shielding sheet 120 and the spacer ring 110, so as to change the position and the dimension of the second through hole 1211 of the light-shielding sheet 120 to meet the requirement of the optical lens on the light-passing hole, thereby ensuring that the lens has good optical performance.

Further, after the light-shielding sheet 120 is mounted on the spacer ring 110, in order to further enhance the connection stability between the light-shielding sheet 120 and the spacer ring 110 under the condition that the inner diameter of the light-shielding sheet 120 satisfies the optical performance of the lens, in some embodiments, the second outer peripheral wall surface 122 of the light-shielding sheet 120 is attached to the first inner peripheral wall surface 111 of the spacer ring 110, that is, the connecting member 130 is just completely embedded in the spacer ring 110, and the corresponding light-shielding sheet 120 is just not embedded in the spacer ring 110; of course, in some embodiments, the outer peripheral wall surface 122 of the louver 120 is located within the spacer ring 110, that is, the connecting member 130 is embedded within the spacer ring 110 while a portion of the louver 110 (the outer end of the louver 120 near the second outer peripheral wall surface 122 thereof) is also embedded within the spacer ring 110.

It can be understood that the connecting member 130, which is an intermediate member for connecting the louver 120 and the spacer ring 110, has a shape structure that directly affects the stability of the connection between the louver 120 and the spacer ring 110. In some embodiments, as shown in fig. 4, the connecting member 130 includes a connecting portion 131, the connecting portion 131 is annular, the connecting portion 131 has an inner annular wall surface (an inner annular surface on the connecting portion 131 on a side close to the hole axis), and the inner annular wall surface of the connecting portion 131 is connected to the second outer circumferential wall surface 122 of the louver 120, and the connecting portion 131 is embedded in the spacer ring 110, that is, the circumferential direction of the second outer circumferential wall surface 122 of the louver 120 is surrounded and covered by the connecting portion 131. In other embodiments, as shown in fig. 3, the connection member 130 includes a plurality of (two or more) connection portions 131, the plurality of connection portions 131 are arranged at intervals along the circumferential direction of the second outer circumferential wall surface 122 of the louver 120, for example, the plurality of connection portions 131 may be arranged on the second outer circumferential wall surface 122 of the louver 120 at arbitrary intervals, that is, the intervals between two adjacent connection portions 131 are not equal, in order to enhance the connection stability between the louver 120 and the spacer ring 110, optionally, the plurality of connection portions 131 are arranged at equal intervals along the circumferential direction of the second outer circumferential wall surface 122 of the louver 120, and each connection portion 131 is embedded in the spacer ring 110.

Referring to fig. 6 to 9, it can be understood that, when the connecting member 130 includes one or more connecting portions 131, in order to enhance the connecting stability between the light shielding sheet 120 and the spacer ring 110, in the first embodiment, each connecting portion 131a at least penetrates through one connecting hole 132a, and it should be noted that the number of the connecting holes 132a is not limited herein, and of course, the larger the number of the connecting holes 132a is, the more the number is, the more the designer needs to reasonably set the number of the connecting holes 132a in consideration of the rigidity and the like of the connecting member 130 after being opened, and the shape of the connecting holes 132a is not limited herein, for example, the cross section of the connecting holes 132a may be circular or square, the plurality of connection holes 132a may be arbitrarily distributed on the corresponding connection portion 131a, and of course, in order to make the stress applied to each of the connection portions 131a uniform, the connection holes 132a on each connection portion 131a may be alternatively arranged at equal intervals around the second outer circumferential wall surface 122 of the light-shielding sheet 120. Through the plurality of connecting holes 132a formed in each connecting portion 131a, the inside of each connecting hole 132a can be filled with the material of the spacer ring 110, so that the contact area between the connecting portion 131a and the spacer ring 110 is increased, the connection stability between the connecting member 130 and the spacer ring 110 is enhanced, meanwhile, the material of the spacer ring 110 filled in each connecting hole 132a can limit the connecting member 130, and the connecting member 130 can be prevented from loosening relative to the spacer ring 110 through the mutual matching of the plurality of connecting holes 132a, so that the effect of enhancing the connection stability between the light shielding sheet 120 and the spacer ring 110 is achieved.

Referring to fig. 10 and 11, in the second embodiment, the connecting member 130 further includes embedded portions 132b equal in number to the connecting portions 131b, and each embedded portion 132b is connected to a side of the corresponding connecting portion 131b facing away from the second peripheral wall surface 122 of the light-shielding sheet 120. For example, when the connecting member 130 includes a connecting portion 131b having a ring shape, the connecting member 130 correspondingly further includes an embedding portion 132b, and the embedding portion 132b is connected to a side of the connecting portion 131b facing away from the second peripheral wall surface 122 of the light shielding sheet 120, that is, the embedding portion 132b also has a ring shape, and an inner ring surface of the embedding portion 132b is connected to a side of the connecting portion 131b facing away from the second peripheral wall surface 122 of the light shielding sheet 120; when the connection member 130 includes a plurality of connection portions 131b, the connection member 130 correspondingly includes a plurality of insertion portions 132b, and one insertion portion 132b is correspondingly connected to one connection portion 131 b. By providing the embedding portion 132b at one side of each of the connection portions 131b, the embedding portion 132b increases a contact area between the connection member 130 and the spacer ring 110 so as to increase connection stability therebetween.

Referring to fig. 12 and 13, a first included angle α is formed between the embedding portion 132b and the connecting portion 131b, and the first included angle α satisfies the following conditional expression: 0 < alpha < 180. A first included angle α exists between the embedding portion 132b and the connecting portion 131b, and the first included angle α may be an acute angle or an obtuse angle.
