A lens assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-2, the lens assembly 100 may be used in a camera 200 of an electronic device 300.

As shown in fig. 1, the lens assembly 100 of the camera 200 according to the embodiment of the present invention includes a plurality of lenses (e.g., the first lens 10, the second lens 20, the third lens 30, and the fourth lens 40 shown in fig. 1), a filter 70, and an encapsulation portion 50. The lenses may be stacked, with at least one pair of adjacent lenses in the lenses, with a gap between the adjacent lenses. Specifically, the plurality of lenses of the lens assembly 100 may be stacked in the up-down direction, and thus the zoom requirement of the camera 200 may be satisfied. The gap between the two adjacent lenses can be filled with rare gas, so that the imaging effect of the camera 200 can be improved. The filter 70 and the plurality of lenses are stacked.

As shown in fig. 1, the encapsulating portion 50 may be integrally injection-molded with the filter sheet 70 and the multi-piece lens, so that the overall size of the lens assembly 100 may be reduced, the overall size of the camera 200 may be further reduced, and the precise manufacturing of the camera 200 may be realized. Further, with filter 70 and the encapsulation of multi-disc lens together, can promote the integrated degree of lens subassembly 100, can promote the anti-shake performance of lens subassembly 100 from this, and then can promote camera 200's formation of image effect. Part of the sealing portion 50 can surround the periphery of the lens, at least part of the edge of the lens is embedded in the sealing portion 50, part of the sealing portion 50 can surround the periphery of the filter 70, and at least part of the edge of the filter 70 is embedded in the sealing portion 50, so that the connection among the lens, the filter 70 and the sealing portion 50 can be firmer.

As shown in fig. 1, the inner peripheral wall of the packing portion 50 located in the gap is a reference surface on which an adhesive layer 60 is coated. Specifically, when a gap is formed between two adjacent lenses, the inner peripheral wall of the sealing portion 50 located in the gap may be provided with an adhesive layer 60. The adhesive layer 60 may be provided on a part of the inner peripheral wall of the gap, or the adhesive layer 60 may be provided on all the peripheral walls of the gap, and may be selectively provided according to actual use requirements. The adhesive layer 60 may adsorb dust particles in the gap, so as to improve the light transmission effect of the lens assembly 100, and further improve the imaging effect of the camera 200. Alternatively, the adhesive layer 60 may be an oily dust-proof adhesive.

According to the lens assembly 100 of the camera 200 of the embodiment of the invention, the packaging part 50 and the plurality of lenses are integrally molded and packaged, so that the overall size of the lens assembly 100 can be reduced, and the assembly space of the lens assembly 100 can be saved. By providing the adhesive layer 60 on the inner peripheral wall of the packaging portion 50 located in the gap, the adhesive layer 60 can adsorb dust particles in the gap, so that the light transmission effect of the lens assembly 100 can be improved, and the imaging effect of the camera 200 can be improved.

As shown in fig. 1, according to some embodiments of the invention, the peripheral wall of the lens is flush with the peripheral wall of the enclosure 50, and the peripheral wall of the filter 70 may also be flush with the peripheral wall of the enclosure 50. Thereby, structural robustness of the lens assembly 100 may be improved. Specifically, the outer peripheral wall of the lens is flush with the outer peripheral wall of the sealing portion 50, so that the contact area between the lens and the sealing portion 50 can be increased, and the fixing structure of the lens can be more firmly fixed. Similarly, the outer peripheral wall of the filter 70 may be flush with the outer peripheral wall of the sealing portion 50, so that the contact area between the filter 70 and the sealing portion 50 may be increased, and the lens fixing structure may be more stable. It is understood that an assembly gap may be provided between the outer peripheral wall of the lens and the outer peripheral wall of the sealing portion 50, an assembly gap may be provided between the outer peripheral wall of the filter 70 and the outer peripheral wall of the sealing portion 50, and the assembly gap may be filled with a sealing material.

As shown in fig. 1, according to some embodiments of the present invention, in the direction of optical path transmission, the lens located at the most upstream of the optical path is the first lens 10, the lens located at the most downstream of the optical path is the second lens 20, the surface of the first lens 10 on the side away from the second lens 20 is the first surface 110, the end surface of the end of the packaging portion 50 facing the optical path upstream is the first end surface 510, the first end surface 510 is flush with the contour line of the first surface 110, and the filter 70 may be located between the second lens 20 and the first lens 10, so that the overall structure of the lens assembly 100 may be more compact and the assembly space may be saved.

Specifically, the first lens 10 may be located at the uppermost end of the lens assembly 100, the second lens 20 may be located at the lowermost end of the lens assembly 100, and a plurality of lenses and filters 70 may be further disposed between the first lens 10 and the second lens 20. The first surface 110 is located at an upper portion of the first lens 10, and external light firstly enters the lens assembly 100 through the first surface 110 and then sequentially passes through each lens and the filter 70 in the lens assembly 100 in a top-down direction. The uppermost end surface of the encapsulation part 50 is the first end surface 510, and the first surface 110 and the first end surface 510 are arranged flush, so that a plane can be formed approximately at the upper end of the lens assembly 100, thereby facilitating the assembly and fixation of the lens assembly 100. As shown in fig. 1, in some embodiments of the present invention, the first lens 10 may be a convex lens, so as to meet the imaging requirements of the lens.

As shown in fig. 1, according to some embodiments of the present invention, in the direction of optical path transmission, the lens located at the most upstream of the optical path is the first lens 10, the lens located at the most downstream of the optical path is the second lens 20, the surface of the second lens 20 on the side away from the first lens 10 is the second surface 210, the end surface of the end of the packaging portion 50 facing the downstream of the optical path is the second end surface 520, the second end surface 520 is flush with the contour line of the second surface 210, and the filter sheet 70 may be located between the second lens 20 and the first lens 10, so that the overall structure of the lens assembly 100 may be more compact and the assembly space may be saved.

Specifically, the first lens 10 may be located at the uppermost end of the lens assembly 100, the second lens 20 may be located at the lowermost end of the lens assembly 100, a plurality of lenses and filters 70 may be further disposed between the first lens 10 and the second lens 20, and the second surface 210 is located at the lower portion of the second lens 20. After entering the lens assembly 100 through the first lens 10, the external light sequentially passes through each lens and the filter 70 in the lens assembly 100 from top to bottom, and forms a real image of an object after being refracted for multiple times. The lowermost end surface of the packing part 50 is a second end surface 520, and the second end surface 520 is disposed flush with the second surface 210, so that a plane can be formed at the lower end of the lens assembly 100, thereby facilitating the assembly and fixation of the lens assembly 100. As shown in fig. 1, in some embodiments of the present invention, the second lens 20 may be a concave lens, so as to meet the imaging requirements of the lens.

Of course, it is understood that the second lens 20 may also be a convex lens, and the arrangement may be selected according to actual requirements. For example, the lens assembly 100 may include three lenses, wherein the first lens 10 and the second lens 20 are both convex lenses, and the lens located between the first lens 10 and the second lens 20 is a concave lens. When the lens assembly 100 is used for shooting, the first lens 10 may disperse the chromaticity of an object, the concave lens may collect the dispersion, and then the dispersion is refracted twice, and finally a clear object image may be formed in the lens assembly 100.

According to some embodiments of the invention, filter 70 may be blue glass. The blue glass is made of blue glass material (common optical filters are common optical glass), and the blue glass has the effect of filtering infrared light in an absorption mode. Because of the higher transmittance of blue light, the glass filter has better transmittance than red-orange glass filter, can filter infrared light above 630nm (but allows the rest light with wide wave band from ultraviolet to infrared light to pass through), and can filter thoroughly.

The principle and law of refraction of light can be used to derive: the longer the wavelength, the smaller the refractive index; the shorter the wavelength, the larger the refractive index. Therefore, when the light rays enter the camera of the mobile phone and are refracted by the lens, the visible light and the infrared light can form images on different target surfaces. Where the visible light is imaged as a color image and the infrared light is imaged as a black and white image. When we adjust the image formed by visible light, namely image focusing and back focus adjustment, infrared light forms a virtual image on the target surface, thereby affecting the color and quality of the image. The blue glass can filter out infrared light, avoids a target surface virtual image caused by the infrared light, and can restore the real color of an object, thereby solving the problem of image color distortion.

As shown in fig. 1, according to some embodiments of the present invention, the lens may include a light passing part (e.g., the first light passing part 120, the second light passing part 220, the third light passing part 310, and the fourth light passing part 410 shown in fig. 1) and a connection part (e.g., the first connection part 130, the second connection part 230, the third connection part 320, and the fourth connection part 420 shown in fig. 1). The light-passing part is positioned in the middle of the lens, and light can pass through the light-passing part. The connecting portion can extend along the circumferential direction of the light-transmitting portion, and the connecting portion is embedded in the packaging portion 50, so that the lenses can be conveniently mounted and fixed. Optionally, the light-passing portion and the connecting portion may be an integral piece, or the connecting portion and the light-passing portion may be provided as independent components, and the connecting portion and the light-passing portion may be connected together by using a connection method such as clamping, adhesive fixing, or the like.

In some embodiments of the present invention, the connecting portion may be a ring shape, so as to improve the firmness of the lens. Particularly, since the connecting portion is formed in a ring shape, a contact area between the connecting portion and the light passing portion can be increased, the position of the lens can be more firm, the lens shake phenomenon of the lens assembly 100 in the shooting process can be prevented, and the imaging effect of the lens assembly 100 can be improved. It is understood that the connecting portion may be formed in a fan shape, a rectangular shape, or the like, as long as the requirement for connecting and fixing the lens can be satisfied.

In some embodiments of the present invention, the connecting portion may be a plurality of connecting portions, and the plurality of connecting portions are spaced apart along a circumferential direction of the light-passing portion, so that the structure of the lens assembly 100 may be more firm. For example, each of the connection portions may be formed in a fan shape, one end of the connection portion is connected to the encapsulation portion 50, the other end of the connection portion is provided with a fitting groove, and an outer edge of the light-passing portion may be engaged with the fitting groove, thereby facilitating the assembly of the lens assembly 100. Further, the plurality of connecting portions may be evenly spaced in the circumferential direction of the light passing portion, so that the stress of the passing portion may be more even, and the imaging effect of the lens assembly 100 may be improved.

As shown in fig. 2, a camera 200 according to an embodiment of the present invention includes the lens assembly 100 according to the above-described embodiment of the present invention.

According to the camera 200 of the embodiment of the invention, by arranging the lens assembly 100, the lens assembly 100 is integrally injection-molded and encapsulated with the plurality of lenses by the encapsulating part 50, so that the overall size of the lens assembly 100 can be reduced, and the assembling space of the lens assembly 100 can be saved. The lens assembly 100 is provided with the adhesive layer 60 on the inner peripheral wall of the packaging portion 50 located in the gap, and the adhesive layer 60 can adsorb dust particles in the gap, so that the light transmission effect of the lens assembly 100 can be improved, and the imaging effect of the camera 200 can be further improved.
