Description

Technical Field

[0001] This application belongs to the field of optical technology, and particularly relates to a lens and an electronic product having the lens. Background Art

[0002] Currently, the lenses inside the lens of an electronic product are usually made of plastic. Plastic lenses are prone to deformation in an environment of high temperature (between 60°C and 120°C) and high humidity (between 60% and 100%). Based on this situation, in the prior art, a hard metal spacer is usually arranged between two adjacent lenses that are more susceptible to temperature and humidity. However, since the hard metal spacer does not deform with the deformation of the adjacent lenses, this will cause the space of the deformed lens to be limited, and the lens is prone to deformation, that is, the relative position between the lenses inside the lens changes, resulting in the variation of the field curvature of the lens, and thus the picture taken by the lens is prone to the situation of poor reliability resolution, that is, the picture taken by the lens is not clear. Summary of the Invention

[0003] This application aims to at least solve to some extent the technical problem that the plastic lenses in the lens are greatly affected by temperature and humidity, the lenses are prone to deformation, resulting in the variation of the field curvature of the lens, and the picture taken by the lens is not clear. For this reason, this application provides a lens and an electronic product having the lens.

[0008] Wherein, the manufacturing material of the shape memory alloy spacer is nickel alloy.

[0009] Wherein, a plurality of annular grooves are arranged on the inner annular wall of the lens barrel along the extending direction of the lens barrel;

[0010] The shape memory alloy spacer includes a spacer main body and an inclined surface. The spacer main body is a ring-shaped structure, the inclined surface is arranged on the inner side wall of the spacer main body, and the inclination direction of the inclined surface forms an angle with the axis of the spacer main body.

[0011] Among them, opposite upper and lower support surfaces are provided on the spacer body, and the upper support surface and the lower support surface are respectively abutted against two adjacent lenses.

[0012] Among them, a portion of the lower support surface of the spacer body near the inner circumference is abutted against the lens located below, a portion of the lower support surface of the spacer body near the outer circumference is clamped in its corresponding annular groove, and the upper support surface of the spacer body is abutted against the lens located above to determine the distance between the two lenses.

[0031] In order to enable those skilled in the art in the technical field to which the present application belongs to understand the present application more clearly, the technical solutions of the present application will be described in detail below with reference to the accompanying drawings and through specific embodiments.

[0032] In the related art, plastic lenses in a lens are greatly affected by temperature and humidity, and the lenses are prone to deformation, resulting in the variation of the field curvature of the lens and the technical problem that the pictures taken by the lens are not clear. The embodiments of the present application provide a lens that can at least to some extent solve the technical problems that plastic lenses are greatly affected by temperature and humidity, the lenses are prone to deformation, resulting in the variation of the field curvature of the lens, and the pictures taken by the lens are not clear.

[0033] The present application will be described below with reference to the accompanying drawings and in reference to specific embodiments:

[0034] As Figures 1 to 9 shown, the embodiments of the present application provide a lens, which includes a lens barrel 1, a lens 2, and a shape memory alloy spacer 3.

[0035] In some embodiments, there are multiple lenses 2 as described above. The multiple lenses 2 are arranged in sequence along the extending direction of the lens barrel 1. Specifically, there is a gap between two adjacent lenses 2, that is, the multiple lenses 2 are arranged at intervals along the extending direction of the lens barrel 1. The memory metal spacer 3 is arranged between two adjacent lenses 2; among them,

[0036] When two adjacent lenses 2 are deformed, the memory metal spacer 3 is adapted to fit with the two deformed lenses 2. Specifically, the lens 2 in the present application is made of plastic material. When the lens is in an environment of high temperature (the temperature is between 60°C and 120°C) and high humidity (the humidity is between 60% and 100%), the lenses 2 in the lens are likely to be deformed, that is, the lenses 2 will absorb water and expand. At this time, by arranging the memory metal spacer 3 between two adjacent deformed lenses 2, the memory metal spacer 3 is adapted to fit with the two deformed lenses 2, that is, the memory metal spacer 3 has the ability of elastic deformation. After it undergoes elastic deformation, it can return to the original state. In this way, it can prevent the field curvature of the lens from changing and ensure the clarity of the picture taken by the lens.

[0037] It should be noted that since the multiple lenses 2 are stacked in sequence along the extending direction of the lens barrel 1, by adding the memory metal spacer 3, the tightness between adjacent lenses 2 can be increased, and the situation of the lenses 2 falling off can be prevented.

[0038] As Figure 1 shown, in some embodiments of the present application, the manufacturing material of the above-mentioned memory metal spacer 3 is nickel alloy. Specifically, in a high-temperature environment, this alloy can be formed into any desired shape. In a relatively high-temperature environment, the nickel alloy can be compressed. However, when the memory metal spacer 3 made of nickel alloy is at normal temperature, it will remember its original shape and return to its original state.

[0039] It should be noted that since the nickel alloy has memory, it can automatically return to its original shape, and the memory metal spacer 3 made of nickel alloy can be repeatedly deformed and restored multiple times. No matter how it is changed, the memory metal spacer 3 can always remember its original shape. At a suitable temperature (generally referring to the temperature before the initial deformation), it will accurately return to the original shape without being affected by the deformed shape.

[0040] As Figure 1 shown, in some embodiments of the present application, a plurality of annular grooves 11 are formed at intervals along the extending direction of the inner ring wall of the above-mentioned lens barrel 1.

[0041] In this embodiment, the provision of multiple annular grooves 11 is suitable for clamping the corresponding lenses 2 and memory metal spacers 3. On one side of the lens 2 facing away from its corresponding annular groove 11, a memory metal spacer 3 for clamping the lens 2 is provided, and a lens 2 is provided again on the memory metal spacer 3. In this order, the lenses 2 and the memory metal spacers 3 are alternately arranged in sequence;

[0042] Take Figure 1 as an example to illustrate the above structure. The lower lens 2 is clamped in its corresponding annular groove 11, and a memory metal spacer 3 is provided above it. Among them, the memory metal spacer 3 includes a spacer body 33. The spacer body 33 is a ring-shaped structure adapted to the lens 2. Two opposite upper support surfaces 331 and lower support surfaces 332 are provided on the spacer body 33, that is, the two end faces of the spacer body 33 are the upper support surface 331 and the lower support surface 332 respectively. A part of the lower support surface 332 of the spacer body 33 (a part of the lower support surface 332 close to the inner circumference) abuts on the lower lens 2, and another part of the lower support surface 332 of the spacer body 33 (a part of the lower support surface 332 close to the outer circumference) is clamped in its corresponding annular groove 11. The upper support surface 331 of the spacer body 33 abuts on the upper lens 2 to determine the distance between the two lenses 2;

[0043] At the same time, the part of the upper lens 2 located outside the spacer body 33 is clamped at the corresponding annular groove 11, realizing the fixation of the position of the lens 2. In this way, it can prevent the memory metal spacer 3 from falling off. By clamping the lens 2 in the corresponding annular groove 11, the situation of the lens 2 falling off can be avoided.

[0044] Such as Figures 1 to 3 shown, the memory metal spacer 3 further includes an inclined surface 31. In this embodiment, the upper edge of the inclined surface 31 is connected to the upper support surface 331 of the spacer body 33, the lower edge of the inclined surface 31 is connected to the lower support surface 332 of the spacer body 33, and the inclination direction of the inclined surface 31 is set at an angle with the axis of the spacer body 33;

[0045] The provision of the inclined surface 31 will directly affect the reflection or refraction behavior of light and affect the optical performance. In this embodiment, the inner diameter of the upper support surface 331 is larger than the inner diameter of the lower support surface 332, so that the inclined surface 31 is inclined away from the center of the spacer body 33 on the inner side wall of the spacer body 33 from bottom to top. Refer to Figure 1 to determine the irradiation range of the lens through the inclined surface 31 and ensure the imaging quality and focusing accuracy of the lens.

[0046] Such as Figure 2 and Figure 3As shown, the memory metal spacer 3 further includes a step 32, which is provided at the connection between the upper support surface 331 and the inclined surface 31. The provision of the step 32 can reduce the thickness of the inner side wall of the spacer body 33, so as to change the inclination angle of the inclined surface 31, enabling it to meet the imaging quality and focusing accuracy of the lens.

[0047] As Figure 1 shown, in an alternative embodiment of the present application, the above-mentioned spacer body 33 is disposed between two deformed lenses 2. Specifically, since the material of the lens 2 is usually plastic, when the lens is in an environment of high temperature (temperature between 60°C and 120°C) and high humidity (humidity between 60% and 100%), the lens 2 in the lens will easily deform, that is, the lens 2 will absorb water and expand. At this time, by disposing the spacer body 33 between two adjacent deformed lenses 2, the spacer body 33 is adapted to fit with the two deformed lenses 2, that is, the spacer body 33 has the ability of elastic deformation and can return to its original state after elastic deformation. In this way, the field curvature of the lens can be prevented from changing, ensuring the clarity of the lens shooting image.

[0048] In some embodiments of the present application, the upper support surface 331 of the above-mentioned spacer body 33 is in contact with one of the deformed lenses 2, and the lower support surface 332 of the spacer body 33 is in contact with the other of the deformed lenses 2. Specifically, by the upper support surface 331 of the spacer body 33 being in contact with one of the deformed lenses 2 and the lower support surface 332 of the spacer body 33 being in contact with the other of the deformed lenses 2, it can be ensured that there is a tight fit between the deformed lens 2 and the spacer body 33, preventing looseness.

[0049] As Figure 1 shown, in an alternative embodiment of the present application, each lens 2 is respectively disposed in a corresponding annular groove 11. Specifically, each lens 2 is respectively embedded in a corresponding annular groove 11, which can effectively prevent the lens 2 from falling out of the annular groove 11. In addition, one lens 2 is clamped in a corresponding annular groove 11, that is, the lens 2 and the annular groove 11 are arranged in a one-to-one correspondence.

[0050] As Figures 4 to 6 shown, the figure schematically shows that before the lens is affected by the high temperature and high humidity environment, neither the lens 2 nor the memory metal spacer 3 is deformed. When encountering a high temperature and high humidity environment, the memory metal spacer 3 will deform as the two adjacent lenses 2 deform. However, when the high temperature and high humidity environment is eliminated, the memory metal spacer 3 will return to its original state and is not affected by the previous deformation, having shape recoverability.

[0051] As Figures 7 to 9As shown Figure 7 Before the lens of the present application is affected by high temperature and high humidity environments, the optical curves are almost in a unified form. However, when the lens is in a high temperature and high humidity environment, the optical curves will be in a non-unified state (see Figure 8 ). When the high temperature and high humidity environment returns to its previous state, Figure 9 the optical curve diagram shown Figure 7 is almost the same as the optical curve diagram shown

[0052] Based on the same inventive concept, an embodiment of the present application further provides an electronic product, including an electronic product body (not shown in the figure) and the lens described in the above embodiment provided on the electronic product body. Specifically, the lens 2 in the electronic product of the present application is made of plastic material. When the lens is in a high temperature (temperature between 60°C and 120°C) and high humidity (humidity between 60% and 100%) environment, the lens 2 in the lens will easily deform, that is, the lens 2 will absorb water and expand. At this time, by arranging the shape memory metal spacer 3 between two adjacent deformed lenses 2, the shape memory metal spacer 3 is adapted to fit with the two deformed lenses 2, that is, the shape memory metal spacer 3 has the ability of elastic deformation and can return to its original state after elastic deformation. In this way, it is possible to prevent the field curvature of the lens from changing and ensure the clarity of the lens shooting image.

[0053] In a specific embodiment of the present application, the electronic product can be a smart camera, a smart phone, a digital camera, etc.

[0054] In summary, the lens 2 in the present application is made of plastic material. When the lens is in a high temperature (temperature between 60°C and 120°C) and high humidity (humidity between 60% and 100%) environment, the lens 2 in the lens will easily deform, that is, the lens 2 will absorb water and expand. At this time, by arranging the shape memory metal spacer 3 between two adjacent deformed lenses 2, the shape memory metal spacer 3 is adapted to fit with the two deformed lenses 2, that is, the shape memory metal spacer 3 has the ability of elastic deformation and can return to its original state after elastic deformation. In this way, it is possible to prevent the field curvature of the lens from changing and ensure the clarity of the lens shooting image.
