As shown in fig. 1 and 2, a lens assembly 1 of a camera 100 according to an embodiment of the present invention includes: a plurality of lenses 11 and a sealing portion 12.

Specifically, as shown in fig. 1, a plurality of lenses 11 are stacked. The plurality of lenses 11 may include dust-proof lenses, refractive lenses, and the like. The multiple layers of lenses 11 are stacked, so that the lenses 11 can better perform their functions and do not interfere with each other.

As shown in fig. 1 and 2, a plurality of lenses 11 are stacked, a sealing portion 12 and the plurality of lenses 11 are integrally injection-molded and sealed, the sealing portion 12 surrounds the periphery of the lenses 11, at least part of the edge of the lenses 11 is embedded in the sealing portion 12, a filter 13 is formed by etching part of the sealing portion 12, and the filter 13 and the lenses 11 are stacked. The packaging part 12 and the plurality of lenses 11 are packaged integrally, so that the lenses 11 can be firmly connected to the packaging part 12, and the lenses 11 are prevented from falling off or displacing under the action of external force. By forming the filter 13 by etching on a part of the structure of the package portion 12, the filter 13 does not need to be additionally arranged, thereby saving space and reducing the overall height of the lens assembly 1.

Specifically, in the etching operation, a layer of a glue medium (e.g., photoresist) is first applied to the central region of the package portion 12, then photolithography etching is performed at the position where the glue medium is applied, and finally the portion to be removed is etched away by the solution, thereby completing the etching process.

According to the lens assembly 1 of the camera 100, the plurality of lenses 11 are integrally injection-molded and encapsulated through the encapsulating part 12, the encapsulating part 12 surrounds the periphery of the lenses 11, part of the structure of the encapsulating part 12 forms the filter 13 through etching, and then the filter 13 and the encapsulating part 12 form an integral piece, so that the structural strength of the encapsulating part 12 and the filter 13 is enhanced, the structure that the filter is fixed on the lens assembly by using a bracket in the related art is cancelled, the distance between the filter 13 and the lenses 11 is reduced, the assembling efficiency is improved, and the lens assembly 1 is miniaturized.

According to some embodiments of the invention, as shown in fig. 1 and 2, the peripheral wall of the lens 11 is flush with the peripheral wall of the enclosure 12. Therefore, the packaging part 12 is more attached to the lens 11, the size of the packaging part 12 is reduced while the packaging strength is ensured, the size and the size of the lens assembly 1 are further reduced, and the lens assembly 1 is miniaturized.

According to some embodiments of the present invention, as shown in fig. 2 and 3, the filter 13 is located downstream (below as shown in fig. 2) of the plurality of lenses 11 in the optical path propagation direction. The filter 13 can filter stray light incident to the camera 100, and enhance the contrast of color, so that the shot scene is clearer and more vivid. In addition, by disposing the filter 13 downstream (below as shown in fig. 2) of the plurality of lenses 11, the lenses 11 can protect the filter 13 well.

According to some embodiments of the present invention, as shown in fig. 1 and fig. 2, in the direction of optical path transmission, the lens 11 located at the most upstream (upper side as shown in fig. 1) of the optical path is the first lens 111, the lens 11 located at the most downstream (lower side as shown in fig. 1) of the optical path is the second lens 112, the surface of the side (upper side as shown in fig. 1) of the first lens 111 away from the second lens 112 is the first surface 115, the end surface of the end (upper end as shown in fig. 1) of the packaging part 12 facing the optical path upstream is the first end surface 117, the first end surface 117 is flush with the contour line of the first surface 115, and the filter 13 is located at the side (upper side as shown in fig. 2) of the second lens 112 away from the first lens 111. Therefore, when the packaging part 12 and the lens 11 are integrally molded, the first end surface 117 of the packaging part 12 is more attached to the first lens 111, and the packaging part 12 is not easy to damage the first lens 111, so that the difficulty of the injection molding packaging process is reduced, and the excellent rate of injection molding packaging is improved. In addition, the filter 13 is disposed on the side of the second lens 112 away from the first lens 111, so that dust or small particles can be effectively prevented from falling on the filter 13.

Further, as shown in fig. 1, the first mirror 111 may be a convex lens. The convex lens has a focusing function, when a user shoots, a scene generates an inverted and reduced optical image through the convex lens, and then the scene with a wider visual angle can be focused in the camera 100 through the convex lens. In addition, the convex lens can isolate dust or small particles at the outer side of the lens assembly 1, and the convex lens is convenient to scrub, so that the dust or the small particles can be conveniently removed from the lens assembly 1.

According to some embodiments of the present invention, as shown in fig. 1 and fig. 2, in the optical path transmission direction, the lens 11 located at the most upstream (upper side as shown in fig. 1) of the optical path is the first lens 111, the lens 11 located at the most downstream (lower side as shown in fig. 1) of the optical path is the second lens 112, the filter 13 is located at a side (upper side as shown in fig. 2) of the second lens 112 away from the first lens 111, a surface of the filter 13 at a side (lower side as shown in fig. 1) away from the first lens 111 is the second surface 116, an end surface of one end (lower end as shown in fig. 1) of the packaging part 12 facing the downstream of the optical path is the second end surface 118, and the second end surface 118 is flush with a contour line of the second surface 116. Therefore, when the packaging part 12 and the lens 11 are integrally molded and packaged, the second end face 118 of the packaging part 12 is more attached to the filter sheet 13, the filter sheet 13 is not easily damaged by the packaging part 12, the difficulty of the injection molding packaging process is reduced, and the excellent rate of injection molding packaging is improved. In addition, the filter 13 is disposed on the side of the second lens 112 away from the first lens 111, so that dust or small particles can be effectively prevented from falling on the filter 13.

According to some embodiments of the invention, as shown in FIG. 1, the second optic 112 may be a concave lens. The concave lens has the function of diverging light, and the light projected on the concave lens through the first lens 111 can be incident on the image sensor through the imaging after divergence, so that the image sensor can analyze and process the image, and further clear imaging can be obtained.

According to some embodiments of the present invention, as shown in fig. 1, the lens 11 may include a light passing portion 113 and a connecting portion 114, the connecting portion 114 extending along a circumferential direction of the light passing portion 113, the connecting portion 114 being embedded in the package portion 12. When a user takes a picture, the light can be transmitted to the image processor through the light-passing portion 113, and the connecting portion 114 is used for connecting and fixing the light-passing portion 113. On the premise of ensuring that the light passage of the light passing part 113 is not obstructed, the connecting part 114 is embedded in the packaging part 12, so that the volumes of the connecting part 114 of the lens 11 and the packaging part 12 are reduced, and the lens assembly 1 is miniaturized.

Further, as shown in fig. 1, the connecting portion 114 has a ring shape. The annular connecting portion 114 facilitates the packaging of the packaging portion 12 to the connecting portion 114, improves the packaging effect of the packaging portion 12 to the connecting portion 114, and further enhances the limiting and fixing of the packaging portion 12 to the lens 11. In addition, the annular connecting portion 114 can increase the contact area between the packaging portion 12 and the connecting portion 114, reduce the contact stress between the packaging portion 12 and the connecting portion 114, and thus reduce the occurrence of cracks in the connecting portion 114 during the integral packaging process or under the action of external force.

In some embodiments of the present invention, the connection portion 114 is plural, and the plural connection portions 114 are distributed at intervals along the circumferential direction of the light passing portion 113. Therefore, the connection stability between the connecting portion 114 and the package portion 12 is ensured, and the complexity of the manufacturing process of the connecting portion 114 is reduced, so that the manufacturing cost of the lens 11 is reduced, and the yield of the manufacturing of the connecting portion 114 is improved.

Further, the touch panel may cover the display panel, and when the touch panel detects a touch operation thereon or nearby, the touch panel transmits the touch operation to the processor to determine the type of the touch event, and then the processor provides a corresponding visual output on the display panel according to the type of the touch event.

The audio circuitry, speaker, and microphone may provide an audio interface between a user and the electronic device 1000. The audio circuit can transmit the electric signal converted from the received audio data to the loudspeaker, and the electric signal is converted into a sound signal by the loudspeaker to be output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit and converted into audio data, which is then output to the processor for processing, and then transmitted to another electronic device 1000 via the rf circuit, or output to the memory for further processing.

The processor is a control center of the electronic device 1000, is installed on the circuit board assembly, connects various parts of the whole electronic device 1000 by using various interfaces and lines, and performs various functions of the electronic device 1000 and processes data by operating or executing software programs and/or modules stored in the memory and calling data stored in the memory, thereby performing overall monitoring of the electronic device 1000. Alternatively, the processor may include one or more processing units; preferably, the processor may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.
