The lens 300 comprises a lens barrel 10 and an optical component 30. The optical component 30 is arranged in the lens barrel 10. Specifically, the lens barrel 10 is provided with a light passing hole 101. The inner side wall of the lens barrel 10 is provided with a bearing portion 12. The bearing portion 12 comprises at least one bearing surface 121 in the axial direction X of the light passing hole 101.

At least one of the at least one bearing surface 121 and the abutting surface 301 is provided with a spiral structure 20. The bearing portion 12 and the optical component 30 form a flow guide channel 102 at the spiral structure 20.

[0031] It should be noted that, Figure 2 The purpose is only to illustrate the setting mode between mirror barrel 10 and optical component 30, and not to make specific limitation on the connection position, connection relationship and specific structure of each element. Figure 2 It is only the structure of the lens 300 illustrated by the utility model embodiment, and does not constitute specific limitation on the lens 300. In other embodiments of the utility model, the lens 300 can include more or fewer components than Figure 2 the lens 300 shown, or combine certain components, or different components, for example, the lens 300 can also include but is not limited to filling piece, limiting piece, partition piece and the like.

[0032] The abutting portion 12 includes two abutting surfaces 121 arranged oppositely in the axial direction X of the light hole 101. Both of the two abutting surfaces 121 are provided with spiral structure 20. At least one of the abutting surface 121 and the abutting surface 301 is provided with spiral structure 20. For example, at least one of the abutting surface 121 is provided with spiral structure 20, and the abutting surface 301 is not provided with spiral structure 20; or both of the two abutting surfaces 121 are not provided with spiral structure 20, and the abutting surface 301 is provided with spiral structure 20; or at least one of the abutting surface 121 is provided with spiral structure 20, and the abutting surface 301 is also provided with spiral structure 20. In other embodiments, the abutting portion 12 includes only one abutting surface 121 in the axial direction X of the light hole 101. At least one of the abutting surface 121 and the abutting surface 301 is provided with spiral structure 20.

[0033] The planar spiral shape can be, but is not limited to, a waist-shaped spiral, a circular spiral, or a square spiral. Exemplarily, in the embodiment, the planar spiral shape is a circular spiral, thereby facilitating the molding of the spiral structure 20. The spiral arrangement of the spiral structure 20 can be set according to actual conditions, and the embodiment of the utility model is not specifically limited.

[0034] The optical component 30 includes at least one of, but is not limited to, a lens 32, a filter 31, a light shield (not shown in the figure), and the like. It should be noted that the lens 32 refers to an optical structure for refracting, reflecting, or focusing light, such as a concave mirror, a convex lens, and the like. The filter 31 refers to an optical structure for selectively transmitting or blocking light of a specific wavelength, such as a red filter 31, a blue filter 31, and the like. The light shield is an optical structure for blocking or reducing the passage of light. The number of lenses 32, the number of filters 31, and the number of light shields can all be set to one or more. For example, the lens 32 is provided in multiple, and the light shield is provided between two adjacent lenses 32. The light shield is used to scatter strong light and block stray light, so that the lens 300 has good imaging quality. It should be noted that the optical component 30 can directly or indirectly abut on the spiral structure 20 through a third-party element, and the utility model does not make specific limitations.

[0035] Exemplarily, in the embodiment, the optical component 30 includes the lens 32 and the filter 31. The lens 32 and the filter 31 are stacked along the optical axis direction of the lens 300 and are spaced apart in the lens barrel 10. The filter 31 and the inner side wall of the lens barrel 10 form a gap 105. Specifically, the lens 32 abuts against one of the abutting surfaces 121 of the abutting portion 12, and the filter 31 abuts against another of the abutting surfaces 121 of the abutting portion 12. Both of the abutting surfaces 121 are provided with the spiral structure 20. Thus, the flow guide channel 102 can guide the gas to be discharged to the outside air, thereby improving the exhaust effect of the lens 300. Specifically, the air generated by the close fit of the lens 32 and the abutting portion 12 of the lens barrel 10 can be discharged to the light passing hole 101 along the flow guide channel 102 formed by the lens 32 and the spiral structure 20, and then discharged to the gap 105 between the filter 31 and the inner side wall of the lens barrel 10 along the flow guide channel 102 formed by the filter 31 and the spiral structure 20, and then discharged to the outside air, thereby avoiding the problem of the displacement and rupture of the lens 32 and the filter 31 due to the accumulation and expansion of the gas in the inner cavity enclosed by the lens 32, the filter 31, and the lens barrel 10.

[0036] Of course, in some embodiments, only any one of the two abutting surfaces 121 is provided with the spiral structure 20, and the embodiments of the utility model are not limited in particular. For example, when the abutting surface 121 abutting the lens 32 is provided with the spiral structure 20, the air generated when the lens 32 and the abutting portion 12 of the lens barrel 10 are tightly fitted can be discharged to the air hole 101 along the flow guide channel 102 formed by the lens 32 and the spiral structure 20, and then discharged to the outside air through the gap 105 between the filter 31 and the lens barrel 10. When the abutting surface 121 abutting the filter 31 is provided with the spiral structure 20, part of the air generated when the lens 32 and the abutting portion 12 of the lens barrel 10 are tightly fitted is pressed into the air hole 101, and the rest is pressed to the outside of the lens barrel 10 and discharged to the gap 105 between the filter 31 and the inner wall of the lens barrel 10, and then discharged to the outside air.

[0037] Exemplarily, in the embodiment, the lens barrel 10 is in a cylindrical shape. The air hole 101 penetrates through two end surfaces of the lens barrel 10. The optical component 30 includes a light-transmitting portion 310 and an abutting portion 320. The light-transmitting portion 310 corresponds to the air hole 101, so that external light can enter from the air hole 101 and pass through the light-transmitting portion 310 of the optical component 30. The abutting portion 320 surrounds the edge of the light-transmitting portion 310 and cooperates with the abutting portion 12.

[0038] Please participate together Figure 2 and Figure 3 , Figure 3 is Figure 2 the structure diagram of the spiral line 201 of the spiral structure 20 of the lens 300 of the electronic device 1000 and the air hole 101. In the embodiment, the normal projection of the spiral structure 20 on the axial direction X of the air hole 101 corresponds to the spiral line 201 formed by rotating in the radial direction Y of the air hole 101 from inside to outside. The spiral line 201 includes a plurality of spiral segments 2011 connected in sequence, and the distance D between the adjacent two spiral segments 2011 in the radial direction Y of the air hole 101 remains unchanged from inside to outside. In this way, on the one hand, the air generated when the optical component 30 and the abutting portion 12 are tightly fitted can flow into the air hole 101 along the spiral structure 20, and then be discharged to the outside air through the exhaust channel arranged inside the lens 300, avoiding the problems of displacement and rupture of the optical component 30 due to the expansion of the gas in the inside of the lens 300; on the other hand, the distance D between the adjacent two spiral segments 2011 remains unchanged from inside to outside, which reduces the processing difficulty of the spiral structure 20, avoids the problem of burr caused by uneven distribution of cutting force due to change of processing parameters during processing of the spiral structure 20, and makes the force uniform when the optical component 30 abuts against the spiral structure 20.

[0039] Of course, in some embodiments, the distance D between the adjacent two helical segments 2011 gradually changes from inside to outside in the radial direction Y of the light passing hole 101. For example, the distance D between the adjacent two helical segments 2011 gradually increases from inside to outside in the radial direction Y of the light passing hole 101. In this way, the flow efficiency of the air flowing from the flow channel 102 to the light passing hole 101 is improved, the force exerted by the air on the optical component 30 is reduced, the reliability and stability of the optical component 30 abutting against the abutting portion 12 are improved, and the lens 300 has good imaging quality. In other embodiments, the distance D between the adjacent two helical segments 2011 gradually changes from inside to outside in the radial direction Y of the light passing hole 101 in multiple stages; or, the distance D between the adjacent two helical segments 2011 gradually decreases from inside to outside.

[0040] It should be noted that the distance D between the adjacent two helical segments 2011 refers to the pitch of the helix line 201, in other words, the distance between the adjacent two points on the helix line 201, which is also the distance of the feed motion generated by one revolution of the thread.

[0041] In some embodiments, the helix line 201 is continuously arranged in the circumferential direction Z of the light passing hole 101, and the helical structure 20 is integrally formed with the abutting portion 12. Specifically, the helical structure 20 is formed on the abutting surface 121 by a one-tool machining forming mode. In this way, on the one hand, the machining mode of the helical structure 20 can reduce the generation of burrs, improve the flatness of the helical structure 20, so that the optical component 30 can reliably and stably abut against the abutting portion 12, thereby improving the coaxiality of the optical component 30 and the lens barrel 10, and the lens 300 has good imaging quality; on the other hand, the machining efficiency is improved, and the production cost is saved.

[0042] In other embodiments, the helix line 201 is continuously arranged in the circumferential direction Z of the light passing hole 101, and the helical structure 20 is independently arranged with the abutting portion 12 and fixedly connected, thereby simplifying the machining difficulty of the helical structure 20. In other embodiments, the helix line 201 is discontinuously arranged in the circumferential direction Z of the light passing hole 101. For example, the helical structure 20 can be formed on the abutting surface 121 by a multi-tool machining forming mode, and the embodiments of the present application are not limited in this regard.

[0043] In some embodiments, the lens barrel 10 is provided with a dispensing groove 103 near the abutting portion 12. The dispensing groove 103 is in communication with the flow guide channel 102. In this way, on the one hand, the dispensing groove 103 is in communication with the flow guide channel 102, so that the flow guide channel 102 can also play a role in collecting the overflowed glue 50; on the other hand, the dispensing groove 103 is provided near the abutting portion 12, so that the dispensing groove 103 can prevent the overflowed glue 50 from flowing into the light transmission portion 310 of the optical filter 31 to affect the imaging quality of the lens 300.

[0044] Exemplarily, in the present embodiment, in the axial direction X of the light transmission hole 101, the groove wall of the dispensing groove 103 is located outside the abutting portion 12, the glue part of the dispensing groove 103 is bonded to the top wall of the optical filter 31 and the groove wall of the dispensing groove 103, and the remaining part is bonded to the outside wall of the optical filter 31 and the inside wall of the lens barrel 10, thereby ensuring that the optical filter 31 and the lens barrel 10 are firmly connected together. The glue of the dispensing groove 103 flows from the gap 105 to the bottom of the optical filter 31 under the action of gravity, and due to the provision of the flow guide channel 102, the glue at the bottom of the optical filter 31 is contained in the flow guide channel 102, thereby preventing the overflowed glue 50 from flowing into the light transmission portion 310 of the optical filter 31 to affect the imaging.

[0045] In some embodiments, at least one abutting surface 121 is provided with an overflow groove 104, which is in communication between the dispensing groove 103 and the flow guide channel 102. In this way, the provision of the overflow groove 104 can reduce the overflowed glue 50 in the dispensing groove 103 flowing into the flow guide channel 102, so that the flow guide channel 102 can smoothly and quickly guide the gas inside the lens 300 out.

[0046] Exemplarily, in the present embodiment, the overflow groove 104 is provided at the corner of the abutting portion 12 and the lens barrel 10, thereby providing sufficient space for the provision of the spiral structure 20, preventing the overflowed glue 50 from flowing into the light transmission portion 310 of the optical filter 31 to affect the imaging. The side wall of the overflow groove 104 near the light transmission hole 101 is provided as an inclined surface, thereby facilitating the overflowed excess glue to quickly flow along the inclined surface to the bottom of the overflow groove 104.

[0047] Please refer to Figures 2 to 4 , Figure 4 is Figure 2An enlarged view of the I part of the camera module of the electronic device in FIG. 1. Exemplarily, in the present embodiment, on a longitudinal section parallel to the axial direction X of the light passage hole 101 and passing through the central axis of the light passage hole 101, the spiral structure 20 comprises recessed structures 21 and protruding structures 22. The recessed structures 21 and the protruding structures 22 are arranged alternately. The distance between two adjacent recessed structures 21 or the distance between two adjacent protruding structures 22 is greater than or equal to 0.08 mm. It should be noted that the distance between two adjacent recessed structures 21 or the distance between two adjacent protruding structures 22 is the spacing D of two adjacent spiral segments 2011 in the radial direction Y of the light passage hole 101. The depth H of the recessed structure 21 is greater than or equal to 0.01 mm. The width of the recessed structure 21 is a first width W1, and the first width W1 is greater than or equal to 0.03 mm. The width of the protruding structure 22 is a second width W2, and the second width W2 is greater than or equal to 0.02 mm.

[0048] It can be understood that if the spiral line 201 is too small, the depth H of the recessed structure 21 is too large, and more material remains during processing, thereby increasing the probability of burr generation. If the spiral line 201 is too large, the depth H of the recessed structure 21 is too small, which can reduce the processing efficiency and reduce the good exhaust effect and overflow glue effect of the flow guide channel 102 formed between the spiral structure 20 and the optical component 30. The present embodiment sets the spacing D of two adjacent spiral segments 2011 in the radial direction Y of the light passage hole 101 to be greater than or equal to 0.08 mm, and the depth H of the recessed structure 21 to be greater than or equal to 0.01 mm, thereby avoiding the risk of burr generation of the spiral structure 20 during processing and ensuring that the flow guide channel 102 formed between the spiral structure 20 and the optical component 30 has a good exhaust effect and overflow glue effect.

[0049] The optical component 30 includes an abutting surface 301 abutting against the convex structure 22, and the convex top surface of the convex structure 22 is a plane, thereby improving the stability of the helical structure 20 supporting the optical component 30, improving the stability and reliability of the optical component 30 in the alignment installation relative to the lens barrel 10, and making the lens 300 have good imaging quality. It can be understood that the larger the width of the concave structure 21 is, the better the exhaust and glue overflow effects are, and the smaller the width of the convex structure 22 is, the smaller the abutting surface 121 product between the optical component 30 and the convex structure 22 is, and the greater the contact stress is, thereby easily causing the optical component 30 to be unevenly contacted with the convex structure 22 and affecting the stability. In the embodiment of the utility model, the ratio of the sum of the widths of all the convex structures 22 to the sum of the widths of all the concave structures 21 is greater than or equal to 0.5, thereby ensuring that the flow guide channel 102 formed between the helical structure 20 and the optical component 30 has good exhaust effect and glue overflow effect, and at the same time ensuring that the helical structure 20 has a large enough abutting surface 121 product to support the optical component 30, so as to reduce the influence of the optical component 30 on vibration and impact, improve the stability and reliability of the optical component 30 in the alignment installation relative to the lens barrel 10, and make the lens 300 have good imaging quality.

[0050] It should be noted that the pitch, the depth H, the first width W1 and the second width W2 of the helical line 201 are only used for detailed description, and can be set according to actual needs, the size of the lens barrel 10 and the size of the light passage hole 101 and other factors, and the embodiment of the utility model is not specifically limited. For example, the interval D of the two adjacent helical segments 2011 in the radial direction Y of the light passage hole 101 can be, but is not limited to, 0.08mm, 0.09mm, 0.1mm, 0.15mm or 0.2mm, etc. The depth H of the concave structure 21 can be, but is not limited to, 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm or 0.1mm, etc. The width of the concave structure 21 can be, but is not limited to, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm or 0.1mm, etc. The width of the convex structure 22 is the second width W2, and the second width W2 can be, but is not limited to, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm or 0.1mm, etc.

[0051] Please participate together Figure 2 and Figure 5 , Figure 5 is Figure 1FIG. 2 is a sectional view of a second embodiment of the partial structure of the lens 300 of the electronic device 1000. The structure of the lens 300 of the second embodiment is similar to that of the lens 300 of the first embodiment, except that the lens 300 of the second embodiment further comprises a locking ring 14. The locking ring 14 is screwed with the lens barrel 10 and is arranged in the light passing hole 101. The locking ring 14 is provided with the abutting part 12 for abutting the optical component 30. In this way, on the one hand, the arrangement of the locking ring 14 can simplify the installation and adjustment process of the optical component 30, ensure the accurate centering of the optical component 30, reduce the optical axis deviation, and be suitable for different types and sizes of optical components 30; on the other hand, by abutting the optical component 30 on the locking ring 14, it is also convenient to process the spiral structure 20 on the locking ring 14, which reduces the processing difficulty and production cost of the spiral structure 20.

[0052] In some embodiments, the optical component 30 further comprises a sealing gasket 33. The sealing gasket 33 is arranged between the lens 32 and the abutting part 12. It can be understood that the lens 32 is usually configured as a transparent structure of glass or other materials. The locking ring 14 can be configured as a hard structure such as a metal structure or a ceramic structure, which is easy to scratch and wear when the lens 32 is pressed on the locking ring 14, thereby affecting the imaging quality of the lens 300. The material of the sealing gasket 33 includes but is not limited to at least one of silicone rubber, fluororubber, nitrile rubber, polytetrafluoroethylene, polyurethane and other plastics. The material of the sealing gasket 33 can also include metal materials such as copper or aluminum. In the embodiment of the utility model, the sealing gasket 33 is arranged between the lens 32 and the abutting part 12, so that the sealing gasket 33 can absorb vibration, reduce impact on the lens 32, and make the pressure evenly distributed, avoid local excessive stress on the lens 32, and prevent the lens 32 from deforming or breaking; on the other hand, the sealing gasket 33 effectively blocks dust and pollutants, keeps the lens 32 clean, and prevents moisture from entering, thereby preventing the lens 32 from being damp, so that the lens 300 has good imaging quality.

[0053] In a possible implementation, the lens barrel 10 body can be configured as a metal light shielding structure. On the one hand, the surface of the metal light shielding structure is not easy to scratch and scratch, has high strength and is not easy to deform, and will not be deformed due to excessive assembly pressure during assembly; on the other hand, since the metal light shielding structure itself has a certain weight, it will not be positionally deviated due to static electricity. Of course, in another possible implementation, the lens barrel 10 body can also be configured as a plastic light shielding structure, on the one hand, to reduce production cost; on the other hand, since the plastic light shielding structure has a certain flexibility, it can avoid the problem of lens barrel 10 body breakage during processing, thereby reducing the processing difficulty of the lens barrel 10 body.

[0054] Please participate together Figure 2 and Figure 6 , Figure 6 isFigure 1 The third embodiment of the partial structure of the lens 300 of the electronic device 1000 in FIG. 1 1 is a cross-sectional view. The structure of the lens 300 of the second embodiment is similar to that of the lens 300 of the first embodiment, except that in the second embodiment, the abutting surface is provided with a spiral structure 20, which is defined as a first spiral structure 210; the abutting surface 301 is provided with a spiral structure 20, which is defined as a second spiral structure 220, and the first spiral structure 210 and the second spiral structure 220 are arranged in a superposed manner and form a flow guide channel 102. In this way, the volume of the flow guide channel 102 formed by the abutting portion 12 and the optical component 30 at the spiral structure 20 is increased, so that the flow guide channel 102 has good exhaust effect and overflow glue effect, while ensuring that the spiral structure 20 has a large enough abutting surface 121 to support the optical component 30, so as to reduce the influence of the optical component 30 on vibration and impact, improve the stability and reliability of the alignment installation of the optical component 30 relative to the lens barrel 10, and make the lens 300 have good imaging quality.

[0055] Exemplarily, in the present embodiment, the first spiral structure 210 and the second spiral structure 220 are arranged opposite to each other, and the side wall of the recessed structure 21 of the first spiral structure 210 is flush with the side wall of the recessed structure 21 of the second spiral structure 220, and the side wall of the recessed structure 21 of the first spiral structure 210 and the side wall of the recessed structure 21 of the second spiral structure 220 are smoothly connected, thereby improving the smoothness and reliability of the flow channel of the gas and glue 50 in the flow guide channel 102, and facilitating the processing and molding of the first spiral structure 210 and the second spiral structure 220. In other words, the width of the recessed structure 21 of the first spiral structure 210 is equal to the width of the recessed structure 21 of the second spiral structure 220. Of course, in some embodiments, the width of the recessed structure 21 of the first spiral structure 210 can also be greater than the width of the recessed structure 21 of the second spiral structure 220, thereby reducing the alignment assembly precision requirement of the optical component 30 and the lens barrel 10, and improving the assembly efficiency and assembly yield.

[0056] It should be noted that the arrangement of the second spiral structure 220 in the third embodiment is applicable to the lens barrel 10 of the second embodiment. In the following description of the second embodiment and the third embodiment, the detailed description of the structure which is the same as that of the first embodiment is omitted to avoid repeated description. For example, the structure of the lens barrel 10 in the third embodiment is the same as that of the lens barrel 10 in the first embodiment.

[0057] The above has carried out the detailed introduction to the embodiment of the utility model, the principle and implementation mode of the utility model have been described in this article by applying specific examples, the above embodiment explanation is only for helping understanding the method and its core thought of the utility model; simultaneously, for the general technical personnel of the field, according to the thought of the utility model, there will be changes in specific implementation mode and application range, and the above, the content of the specification should not be understood as the limitation of the utility model.
