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 spacer 70, an adhesive layer 60, 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.

As shown in FIG. 1, a spacer 70 may be provided in a stack with a plurality of lenses, the surface of the spacer 70 may include a working surface 71 and a non-working surface 72, and the non-working surface 72 may have a first texture 73 therein. For example, the spacer 70 may be sandwiched between the lenses, the spacer 70 may be located above or below (e.g., up and down as shown in fig. 1) the lenses, the spacer 70 may be arranged parallel to the lenses, and the spacer 70 may also form an angle with the lenses. The surface of the diaphragm 70 may include a working surface 71 and a non-working surface 72, the non-working surface 72 may be a rugged planar surface, and the non-working surface 72 may have a first texture 73 thereon.

As shown in fig. 1, the encapsulating portion 50 may be integrally injection-molded with the spacer 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 reduced, and the precise manufacturing of the camera 200 may be realized. Further, with the encapsulation of multi-disc lens and spacer 70 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. The sealing portion 50 can surround the periphery of the lens, and at least a part of the edge of the lens is embedded in the sealing portion 50, so that the connection between the lens and the sealing portion 50 can be more firm. The enclosure 50 may surround the outer periphery of the spacer 70 with at least part of the edge of the spacer 70 embedded within the enclosure 50, thereby making the connection between the spacer 70 and the enclosure 50 more secure.

As shown in fig. 1, the inner circumferential wall of the packing part 50 in the gap is a reference surface having a second texture 530 formed by a spark process, and the reference surface is coated with an adhesive layer 60. Specifically, when a gap is formed between two adjacent lenses, the inner peripheral wall of the packaging portion 50 located in the gap may have a second texture 530, and the second texture 530 may be formed by an electric discharge process. The adhesive layer 60 may be provided on a portion of the inner peripheral wall of the gap, for example, the surface of the second ridge 530 may be coated with the adhesive layer 60. The adhesive layer 60 may be provided on all the peripheral walls of the gap, and may be selected according to the actual use requirement. 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 forming the first ridges 73 on the non-working surface 72 of the spacer 70, the roughness of the non-working surface 72 of the spacer 70 can be improved without affecting the effect of the spacer 70, and the reflection of the light irradiated on the non-working surface 72 of the spacer 70 can be converted into slow reflection, and the light reflected by the rough non-working surface 72 can be reflected to the surroundings. The second texture 530 is formed on the reference surface by using an electric spark process, so that the roughness of the inner peripheral wall of the packaging part 50 can be improved, the reflection of light irradiated on the inner peripheral wall of the packaging part 50 can be converted into slow reflection, the light reflected by the rough inner wall surface can be reflected to the periphery, and the conditions that glare is formed in a reflection concentration mode and imaging is influenced can be avoided. In addition, 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.

It should be noted that the "working surface 71" mentioned herein may refer to a surface of the spacer 70 that is a portion that processes and acts on light and may contribute to the imaging result, for example, the "working surface 71" may be a filter, the "working surface 71" may also be a light-transmitting portion, and the "non-working surface 72" may refer to a surface of the spacer 70 that does not substantially act on light and may be a portion for fixing and mounting the spacer 70, for example, the "non-working surface 72" may be a non-light-transmitting portion.

As shown in fig. 1, according to some embodiments of the invention, the reference surface may be an inclined surface that gradually inclines radially outward of the lens in the direction of light transmission. For example, the reference surface may be formed as a ring surface, the cross-sectional area of the reference surface of the package portion 50 gradually increases in the direction in which light is transmitted from the outside of the camera 200 to the inside of the camera 200, i.e., the light may be irradiated from the top to the bottom (up and down as shown in fig. 1), i.e., the reference surface may be formed in a trumpet shape or an expanded shape. Therefore, after the light is reflected by the reference surface, the reflected light is relatively dispersed.

According to further embodiments of the invention, the reference surface may be an inclined surface, the reference surface gradually inclining towards a radially inner side of the lens in a direction of light transmission. For example, the reference surface may be formed as a ring surface, the light may be irradiated from the outside of the camera 200 to the inside of the camera 200, that is, the light may be irradiated from the top to the bottom (up and down as shown in fig. 1), and the cross-sectional area of the reference surface may be gradually reduced, that is, the reference surface may be formed in an inverted trumpet shape or a contracted shape. Therefore, after the light is reflected by the reference surface, the reflected light is relatively dispersed.

According to some embodiments of the invention, the adhesive layer may be an oily dirt repellent glue. The oily dustproof glue has fluidity and adhesiveness, and can be directly brushed on a reference surface. Therefore, the adhesive is convenient to coat, good in adhesion performance and good in dust collection effect.

As shown in fig. 1, in some examples of the present invention, the spacer 70 may be formed in a sheet shape, a surface of the spacer 70 may be coated with a light-blocking layer through which light cannot pass, and the surface of the spacer 70 is formed with the first ridges 73, so that the surface of the spacer 70 is uneven. The spacer 70 may be provided with a through hole penetrating the spacer 70 in an axial direction of the spacer 70, the through hole being near a central position of the spacer 70, and the through hole may partially form the working surface 71 to pass light.

As shown in fig. 1, the non-working surface 72 may have a step 74 therein, according to some embodiments of the invention. It will be appreciated that the first ridges 73 may be in the form of steps. For example, the non-working surface 72 forms a plurality of annular projections that are sequentially nested, with the thickness of the projections increasing or decreasing in a direction from a radially inner side of the spacer 70 to a radially outer side of the spacer 70. Thus, the roughness of the non-working surface 72 can be increased and the step 74 can create a slow reflection of light.

According to some embodiments of the present invention, the thickness of the septum 70 within the non-working surface 72 gradually increases in a direction radially inward to radially outward of the septum 70. In other words, the thickness of the septum 70 at the location of at least a portion of the non-working surface 72 increases gradually as viewed from the center of the septum 70 toward the edge of the septum 70, the non-working surface 72 being an inclined surface, and the distance between the upper and lower opposing portions of the non-working surface 72 increasing gradually. Thereby, the reflection path of the light can be changed.

As shown in FIG. 1, according to other embodiments of the present invention, the thickness of the septa 70 within the non-working surface 72 gradually decreases in a direction from radially inward to radially outward of the septa 70. In other words, the thickness of the diaphragm 70 at least at a portion of the non-working surface 72 gradually decreases as viewed from the center of the diaphragm 70 toward the edge of the diaphragm 70, the non-working surface 72 is an inclined surface, and the distance between the upper and lower opposing portions of the non-working surface 72 gradually decreases. Therefore, the reflection path of the light can be changed, and the packaging is convenient.

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, thereby improving the structural rigidity of the lens assembly 100. 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. It will be understood that a fitting gap may be provided between the outer peripheral wall of the lens and the outer peripheral wall of the sealing portion 50, and the fitting 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, and the first end surface 510 is flush with the contour line of the first surface 110, so that the overall structure of the lens assembly 100 can be more compact and the assembly space can 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 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 in the lens assembly 100 in a direction from top to bottom. 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, 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 second texture 530 is formed on the reference surface by using an electric spark process, so that the roughness of the inner peripheral wall of the packaging part 50 can be improved, the reflection of light irradiated on the inner peripheral wall of the packaging part 50 can be converted into slow reflection, the light reflected by the rough inner wall surface can be reflected to the periphery, and the conditions that glare is formed in a reflection concentration mode and imaging is influenced can be avoided. In addition, 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 improved.
