[0037] Embodiment 1
[0038] like Figures 1 to 4As shown, the first aspect of the present application provides a lens, including a lens barrel 1 and a lens 2; the lens barrel 1 has a accommodating space 11, and the lens barrel 1 is provided with a first opening 12 and a second opening 13 connected to the accommodating space 11 on opposite sides, and the side wall 111 of the accommodating space 11 is dug with at least one groove 112 along the radial direction A of the lens barrel 1, and the side wall 111 is elastic; the outer edge of at least one lens 2 is correspondingly connected with the at least one groove 112; wherein the lens 2 enters the accommodating space 11 along the axial direction B from the second opening 13 to the first opening 12 and is connected with the groove 112.
[0039] Specifically, during the process of manufacturing and assembling the lens, the lens 2 needs to be placed in the accommodating space 11 of the lens barrel 1 to achieve assembly. A first opening 12 and a second opening 13 connected to the accommodating space 11 are provided on opposite sides of the lens barrel 1. In the present application, the first opening 12 is the light inlet of the lens, and the second opening 13 is the light outlet of the lens. During the assembly of the lens 2, it enters the accommodating space 11 of the lens barrel 1 along the axial direction B from the first opening 12 to the second opening 13. In the lens, in order to make more precise adjustments to spherical aberration, coma aberration, astigmatism, chromatic aberration, etc., so that the lens has a better light path, reduces aberrations to obtain better molding quality, when a plurality of lenses 2 are provided in the lens, the size of the lens 2 gradually increases along the direction from the first opening 12 to the second opening 13, and the corresponding size of the second opening 13 is larger than the size of the first opening 12.
[0040] In the present application, at least one groove 112 is excavated on the side wall 111 of the accommodating space 11 along the radial direction A of the lens barrel 1. In order to enable the lens 2 to cooperate with the groove 112 in the process of entering the accommodating space 11 along the axial direction B, the side wall 111 of the accommodating space 11 in the present application is elastic. Since the lens 2 needs to be limited in the groove 112, the outer edge of the lens 2 in the circumferential direction needs to be limited at the bottom of the groove 112. At the same time, the groove wall of the groove 112 also needs to support the surface of the lens 2 on the side of the axial direction B. Therefore, the circumferentially arranged groove wall is close to the accommodating space 11. One end of is more protruding toward the accommodating space 11 than the outer edge of the lens 2, and in the process of placing the lens 2, the lens 2 needs to first pass through the above-mentioned groove wall and enter the groove 112 to be limited, so the groove wall needs to be elastic so that it can be deformed when the lens 2 hits the top to allow the lens 2 to pass through, and the groove wall is formed by the side wall 111 of the accommodating space 11 of the lens barrel 1 to open the groove 112, so the application sets the side wall 111 to be elastic to meet the placement requirements of the lens 2, and the elastic side wall 111 can also play a buffering role for the lens 2, protecting the integrity of the lens 2 during the assembly process. In the present application, the lens barrel 1 can be integrally formed by materials such as rubber, polyurethane, and thermoplastic elastomer, and plastic, metal, and other materials can also be used as the outer shell of the lens barrel 1, and the side wall 111 of the accommodating space 11 of the lens barrel 1 is connected to the elastic material on the surface of the above-mentioned plastic, metal, and other hard materials through processes such as adhesives, hot vulcanization, or secondary injection molding, and the specific process is not limited, as long as it can meet the lens assembly requirements of placing the lens 2 into the groove 112.
[0041] The groove 112 corresponds to the placement of the lens 2, and the number of lenses 2 in the lens is related to the optical performance required by the lens, the size of the lens barrel 1, etc. The present application sets the groove 112 so that the corresponding lens 2 does not need to be compensated and limited by gaskets or pressure rings during assembly, thereby reducing the number of gaskets, pressure rings, and glue painting stations required for lens assembly, saving costs, and in order to avoid deformation or damage caused by the lenses 2 being stacked on each other and under pressure, which affects the optical performance, the lens 2 is limited separately by the groove 112. The number of grooves 112 can be set according to the number of lenses 2 in the lens, or it can be less than the number of lenses 2. The grooves 112 can be set according to the pressure state caused by the different shapes of the lenses 2 in the lens when stacked to reduce the pressure. The number of gaskets or pressure rings in the assembly process can also be reduced by setting the groove 112 according to the goal of reducing costs during the production process. The above purpose can also be achieved by only setting one groove 112.
[0042] In one embodiment of the present application, there is one groove 112, and the groove 112 is located at the end of the lens barrel 1 close to the second opening 13. A lens 2 is placed in the groove 112. The lens 2 is limited by the groove 112 as the lens 2 at the end of the lens. There is no need to set a pressure ring on the side away from other lenses 2 and fix it with a glue painting station. The other lenses 2 in the corresponding lens barrel 1 are stacked and assembled with each other, and gaskets are used in the lens barrel 1 to compensate for the differences in the shapes of the lenses 2.
[0043] In another embodiment of the present application, the number of grooves 112 is one, and the groove 112 is located near the middle of the lens barrel 1, and a lens 2 is placed in the groove 112. In this embodiment, the other lenses 2 in the lens barrel 1 are stacked and arranged on both sides of the lens 2 in the groove 112, and the gaskets are used to compensate for the differences in the appearance of the lenses 2, and a pressure ring is required to be arranged on the side of the lens barrel 1 near the second opening 13 to fix the lens 2 at the inner end of the lens barrel 1. In another embodiment of the present application, two grooves 112 can also be set, and the two grooves 112 are respectively located at the end of the lens barrel 1 near the second opening 13 and the position near the middle of the lens barrel 1. Through the setting of the grooves 112, the corresponding lens 2 does not need to be compensated and limited by gaskets or pressure rings during assembly, thereby reducing the number of gaskets, pressure rings, and glue painting stations required for lens assembly, reducing the manufacturing cost of the lens, and at the same time avoiding deformation or damage of the lens 2, ensuring the optical performance of the lens.
[0044] In a first aspect, the present application provides a lens, comprising a lens barrel 1 and a lens 2; the lens barrel 1 has a accommodating space 11, and opposite sides of the lens barrel 1 are provided with a first opening 12 and a second opening 13 connected to the accommodating space 11, a side wall 111 of the accommodating space 11 is provided with at least one groove 112 along a radial direction A of the lens barrel 1, and the side wall 111 is elastic; the outer edge of at least one lens 2 is correspondingly connected to the at least one groove 112; wherein the lens 2 enters the accommodating space 11 along the axial direction B from the second opening 13 to the first opening 12 and is connected to the groove 112. In the present application, at least one groove 112 is dug in the side wall 111 of the storage space 11 in the lens barrel 1, and the side wall 111 of the storage space 11 is elastic so that the lens 2 can enter the corresponding groove 112 along the axial direction B and then complete the limit, so that the lens 2 in the groove 112 is individually limited without stacking and pressing with other lenses 2 at both ends to complete the assembly, avoiding deformation or damage of the lens 2, ensuring the optical performance of the lens, and the setting of the groove 112 makes it unnecessary for the corresponding lens 2 to be compensated and limited by gaskets or pressure rings during assembly, thereby reducing the number of gaskets, pressure rings, and glue painting stations required for lens assembly, and reducing the manufacturing cost of the lens. Through the application of the present application, the problem that stacking and pressing between lenses 2 will cause deformation or damage of the lens 2 and affect the optical performance, and the use of gaskets, pressure rings and glue painting stations increases the manufacturing cost of the lens is solved.
[0045] like Figure 2 and Figure 3 As shown, in some embodiments, the side wall 111 has a first slope 1111, and the side of the first slope 1111 close to the first opening 12 is more protruding than the side close to the second opening 13; the outer edge of the lens 2 has a second slope 21, and the side of the second slope 21 close to the second opening 13 is more protruding than the side close to the first opening 12, and the second slope 21 is matched and connected with the first slope 1111.
[0046] Specifically, in order to facilitate the lens 2 to enter the groove 112 and be limited after contacting the elastic side wall 111, the present application arranges the side wall 111 to have a first inclined surface 1111, and the outer edge of the lens 2 has a second inclined surface 21, so that the second inclined surface 21 is matched and connected with the first inclined surface 1111, so that in the process of the lens 2 entering the accommodating space 11 along the axial direction B, it can enter the groove 112 adjacent to the side wall 111 through the guiding effect between the two inclined surfaces, and the lens 2 applies a thrust to the first inclined surface 1111 of the side wall 111 through the second inclined surface 21, which can buffer the deformation of the side wall 111, thereby improving the service life of the lens barrel 1 in the present application, and also plays a buffering and protective role for the lens 2. On this basis, the present application sets the first inclined surface 1111 to be protruding on the side closer to the first opening 12 than on the side closer to the second opening 13, and correspondingly, the second inclined surface 21 to be protruding on the side closer to the second opening 13 than on the side closer to the first opening 12. This is because the lens 2 needs to move along the axial direction B from the second opening 13 to the first opening 12 when entering the accommodating space 11. In order to adapt to the movement direction of the lens 2, the above-mentioned inclined surface is set to provide guidance for the lens 2 to enter the groove 112 after contacting the side wall 111.
[0047] like Figure 2 and Figure 3 As shown, in some embodiments, the first inclined surface 1111 forms a preset angle with the axial direction B, and the preset angle is an acute angle; the angle between the second inclined surface 21 and the axial direction B is the same as the preset angle.
[0048] Specifically, the first inclined surface 1111 forms a preset angle with the axial direction B, and the preset angle is an acute angle, so that when the side wall 111 receives the thrust applied by the lens 2 when it pushes against the top, the thrust can be decomposed into two components along two directions parallel to the first inclined surface 1111 and perpendicular to the first inclined surface 1111 under the action of the preset angle of the first inclined surface 1111, and deformed under the action of the two components. The angle between the second inclined surface 21 and the axial direction B is the same as the preset angle, so that the lens 2 can enter the groove 112 adjacent to the side wall 111 through the guiding effect between the first inclined surface 1111 and the second inclined surface 21 to complete the limiting.
[0049] In one embodiment of the present application, the angles between the first bevel 1111, the second bevel 21 and the axial direction B are set in the range of 30° to 60°. When the angle is in the range of 30° to 60°, when the side wall 111 is subjected to the thrust applied by the lens 2 when it moves along the axial direction B, the thrust is decomposed into two components along two directions parallel to the first bevel 1111 and perpendicular to the first bevel 1111, and the side wall 111 is deformed under the action of the two components, so that the lens 2 enters the groove 112 adjacent to the side wall 111 through the guiding effect between the first bevel 1111 and the second bevel 21 to complete the limiting, and the angle range of 30° to 60° makes the side wall 111 in an appropriate deformation amount in two directions, thereby improving the service life of the lens barrel 1 in the present application, and also plays a buffering and protective role for the lens 2.
[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the side wall 111 also has a first straight surface 1112, the first straight surface 1112 is parallel to the axial direction B, and one side of the first straight surface 1112 is connected to the side of the first inclined surface 1111 close to the first opening 12; the outer edge of the lens 2 also has a second straight surface 22, the second straight surface 22 is parallel to the first straight surface 1112, and one side of the second straight surface 22 is connected to the side of the second inclined surface 21 close to the second opening 13.
[0051] Specifically, in order to improve the overall strength of the side wall 111, so that the side wall 111 has an appropriate elastic deformation amount so that the lens 2 can enter the groove 112 after passing through the side wall 111, and can provide sufficient support for the lens 2 when the lens 2 is placed in the groove 112, the side wall 111 in the present application also has a first straight surface 1112, and correspondingly, the outer edge of the lens 2 has a second straight surface 22, one side of the first straight surface 1112 is connected to the side of the first inclined surface 1111 close to the first opening 12, and one side of the second straight surface 22 is connected to the side of the second inclined surface 21 close to the second opening 13, so that the lens 2 can be placed in the groove 112. During the movement from the second opening 13 to the first opening 12 in the axial direction B, the lens 2 is first guided by the first inclined surface 1111 of the side wall 111. At the same time, the side wall 111 undergoes a certain amount of elastic deformation to allow the lens 2 to pass through. The first straight surface 1112 of the side wall 111 increases the thickness of the side wall 111 in the axial direction B to improve the overall structural strength of the side wall 111, thereby ensuring the service life of the side wall 111 and the lens barrel 1. When the lens 2 enters the groove 112, the inner side wall 111 can provide sufficient supporting force to stably limit the lens 2 in the groove 112. It should be noted that the expression of the first straight surface 1112 and the second straight surface 22 in the present application means that when the lens is in a sectional view, the outer edges of the cross sections of the side wall 111 and the lens 2 have straight line characteristics. In the structure of an actual lens, the first straight surface 1112 is a continuous curved surface on one side of the side wall 111, and the second straight surface 22 is a continuous curved surface on the lens 2.
[0052] like Figure 2 and Figure 3 As shown, in some embodiments, the groove bottom of the groove 112 has a third straight surface 1121 , and the third straight surface 1121 is cooperatively connected with the second straight surface 22 .
[0053] Specifically, in order to ensure that the lens 2 is stably placed after entering the groove 112, the present application provides a third straight surface 1121 at the bottom of the groove 112, and the third straight surface 1121 is matched and connected with the second straight surface 22, so that when the lens 2 is placed in the groove 112 in the lens barrel 1, the circumferential outer edge of the lens 2 can be matched with the third straight surface 1121 at the bottom of the groove 112 through the second straight surface 22, so that there can be no gap between the lens 2 and the groove 112 in the radial direction A, thereby avoiding the lens 2 from shifting and shaking in the radial direction A during the use of the lens, and ensuring the optical performance of the lens. It should be noted that, on the basis of having the third straight surface 1121, the shape and structure of the groove 112 can also be adaptively adjusted according to the shape and structure of the different outer edges of different lenses 2, so as to meet the requirement that the lens 2 is stably placed in the groove 112. It should be noted that, in the present application, the third straight surface 1121 refers to the fact that when the lens is in a cross-sectional view, the bottom of the groove 112 has a straight line feature. In the structure of an actual lens, the bottom of the groove 112 is a continuous curved surface.
[0054] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, a plurality of grooves 112 are formed at intervals along the axial direction B on the side wall 111 of the accommodating space 11 , and the outer edges of the plurality of lenses are correspondingly matched and connected with the plurality of grooves 112 .
[0055] Specifically, in one embodiment of the present application, the side wall 111 is provided with a plurality of grooves 112 at intervals along the axial direction B, and the outer edges of the plurality of lenses are correspondingly connected with the plurality of grooves 112. Figure 2 and Figure 3 As shown, the plurality of lenses 2 may also be the number of all lenses 2 required for the lens, such as Figure 6 The multiple lenses 2 shown may also be smaller than the number of lenses 2 required for the lens. In one embodiment, the present application sets grooves 112 near the middle of the lens barrel 1 and on one side near the second opening 13. The present application sets the grooves 112 so that the corresponding lenses 2 do not need gaskets or pressure rings for compensation and limiting during assembly, thereby reducing the number of gaskets, pressure rings, and glue painting stations required for lens assembly, saving costs, and the grooves 112 can prevent the lenses 2 from being stacked on each other and causing deformation or damage after being compressed, which affects the optical performance.
[0056] It should be noted that the corresponding lens 2 without the groove 112 is adaptively provided with a gasket or a pressing ring according to its location and the needs during the assembly process to ensure stable assembly of the lens.
[0057] like Figures 1 to 6 As shown, in some embodiments, the second opening 13 is larger than the first opening 12; the inner diameters of the plurality of grooves 112 decrease along the axial direction B; and the outer diameters of the plurality of lenses 2 decrease along the axial direction B.
[0058] Specifically, in the lens, in order to make more precise adjustments to spherical aberration, coma aberration, astigmatism, chromatic aberration, etc., so as to have a better light path in the lens and reduce aberrations to obtain better molding quality, when a plurality of lenses 2 are provided in the lens, the size of the lenses 2 gradually increases from the first opening 12 to the second opening 13, and the corresponding size of the second opening 13 is larger than the size of the first opening 12. At the same time, the inner diameters of the plurality of grooves 112 decrease along the axial direction B, and the outer diameters of the plurality of lenses 2 decrease along the axial direction B to meet the assembly requirements of the plurality of lenses 2 in the lens.
[0059] like Figures 1 to 6 As shown, in some embodiments, the inner diameter of the side wall 111 of the accommodating space 11 decreases along the axial direction B.
[0060] Specifically, on the basis that the second opening 13 is larger than the first opening 12; the inner diameters of the plurality of grooves 112 decrease along the axial direction B; and the outer diameters of the plurality of lenses 2 decrease along the axial direction B, in order to facilitate the lenses 2 to enter the grooves 112 under the elastic deformation of the side walls 111, the inner diameter of the side walls 111 of the accommodating space 11 of the present application decreases along the axial direction B to ensure smooth assembly of the lenses 2.
