The present application will now be described more fully hereinafter with reference to the accompanying drawings.

Referring to fig. 1, a schematic structural diagram of an electronic device with a camera function in the prior art is shown, the electronic device with the camera function includes a display screen 200, and a light hole 210 is formed on the display screen 200. The electronic device with the image pickup function further comprises a lens 300, wherein the lens 300 comprises a lens barrel 310 and a first lens 320 arranged in the lens barrel 310, wherein the first lens 320 is adjacent to the object side space 400 of the lens 300. The lens barrel 310, in turn, includes a main body 311 and a shielding portion 312, the shielding portion 312 being located at an end of the main body 311. The blocking portion 312 is used to block non-imaging light that may enter the first lens 320, and on the other hand, the blocking portion 312 can also be used to limit the position of the first lens 320 and assist in calibrating the position of the first lens 320 during the assembly of the first lens 320. In addition, the shielding portion 312 has a certain thickness because the shielding portion 312 is integrally formed with the main body 311. Therefore, the lens barrel 310 is partially inserted into the light-passing hole 210 to reduce the thickness of the lens 300, so as to achieve the purpose of reducing the volume of the whole electronic device with the image pickup function. Meanwhile, the diameter of the light-passing hole 210 is equal to that of the lens barrel 310, which causes the light-passing hole 210 to occupy too large area of the display screen 200, resulting in insufficient screen occupation in the display screen.

Therefore, the application provides an electronic device with a camera shooting function, which can increase the screen occupation ratio. Referring to fig. 2, the electronic device with a camera function includes a display 200, the display 200 has a light-passing hole 210, and further includes a lens 300, an object-side space 400 of the lens 300 is connected to the display 200, and the light-passing hole 210 of the display 200 is coaxial with the lens 300. The lens 300 includes a lens barrel 310 and a first lens 320 disposed in the lens barrel 310, the first lens 320 is adjacent to the object side space 400, an end surface 314 of the lens barrel 310 is connected to the display screen 200, and a diameter of the light passing hole 210 is smaller than a diameter of the first lens 320 and larger than or equal to a diameter of an imaging area 321 of the first lens 320.

In the electronic apparatus having the image pickup function, compared with the prior art, the shielding portion 312 with a large thickness in the lens barrel 310 is eliminated, and the end surface 314 of the lens barrel 310 is connected to the display screen 200 instead of being inserted into the light passing hole 210. Therefore, the diameter of the light passing hole 210 can be reduced to a size smaller than that of the first lens 320 to reduce the occupation ratio of the light passing hole 210 on the display screen, thereby increasing the screen occupation ratio. Meanwhile, the light passing radius required for imaging by the first lens 320 can be satisfied by keeping the diameter of the light passing hole 210 greater than or equal to the diameter of the imaging region 321 of the first lens 320. On the other hand, due to the reduction of the diameter of the light through hole 210, the display screen around the light through hole 210 can play a role in shading light, so that the stray light is removed, and the imaging quality is guaranteed. Preferably, a light shielding material may be coated on the surface of the display 200 between the first lens 320 and the display 200 to achieve a better light shielding effect and prevent light leakage from the display 200. Under the above design, the screen occupation ratio can be effectively increased on the premise of ensuring the imaging quality.

In some embodiments, referring to fig. 2 and fig. 3, the lens 300 further includes a light shielding sheet 350, and the light shielding sheet 350 is disposed between the display screen 200 and the first lens element 320 for shielding unnecessary incident light to ensure the imaging quality of the lens 300. In other words, the shielding portion 312 with a larger thickness integrally formed with the main body 311 in the prior art (fig. 1) is replaced by a shielding sheet 350 with a smaller thickness and separately provided from the main body 311, so as to achieve the purpose that a required partial region of the first lens 320 in the lens 300 needs to be shielded.

In one embodiment, referring to fig. 2 and fig. 3, the light shielding sheet 350 includes a light shielding portion 352 and a connecting portion 351, the light shielding portion 352 is attached to the first lens 320, and the connecting portion 351 is connected to the end surface 314 of the lens barrel 310. The light shielding portion 352 is used to block non-imaging light from entering the first lens 320, and the connecting portion 351 is used to stably connect the light shielding sheet 350 between the lens 300 and the display screen 200. By the above design, the stability of the connection of the light-shielding sheet 350 can be enhanced.

In addition to the above embodiments, referring to fig. 2 and fig. 3, the thickness D1 of the connecting portion 351 of the light-shielding sheet 350 is greater than the thickness D2 of the light-shielding sheet 350. Wherein, connecting portion 351 is used for the stable connection of anti-dazzling screen 350 between camera lens 300 and display screen 200, when connecting portion 351 has great thickness, can strengthen connecting portion 351's intensity, and then strengthens anti-dazzling screen 350 stability and life, and anti-dazzling screen 350 is thin to be favorable to the small size of the electronic equipment who has the function of making a video recording. In a specific embodiment, the thickness D1 of the connecting portion 351 is 0.05mm, and the thickness D2 of the light shielding sheet 350 is 0.02mm, and with the above dimensions, not only the stability and the service life of the light shielding sheet 350 can be ensured, but also the volume of the electronic device with the image pickup function can be ensured not to be excessively increased.

In one embodiment, the end surface 314 of the lens barrel 310 is recessed inward to form an annular dispensing groove 360, and the dispensing groove 360 is filled with a whole circle of glue and adhered to the connecting portion 351 of the light shielding sheet 350. In this embodiment, the glue dispensing groove 360 is formed in the end surface 314 to provide a special place for accommodating glue, so that the problems of glue overflow, uneven glue, increased thickness and the like caused by the fact that the glue is filled between the light shielding sheet 350 and the end surface 314 are avoided, and on the other hand, the adhesive force between the light shielding sheet 350 and the end surface 314 can be enhanced through the design. And the whole circle of glue is dispensed in the glue dispensing groove 360, so that the adhesive force between the light shielding sheet 350 and the end surface 314 is further enhanced.

In one embodiment, the dispensing groove 360 extends to the edge of the inner side 315 of the end surface 314 of the lens barrel 310, and forms a step on the inner wall of the lens barrel 310, and the dispensing groove 360 is adjacent to the first lens 320 and the light shielding sheet 350. Through the above design, the first lens 320 and the light shielding sheet 350 can be respectively bonded to the lens barrel 310, so that on one hand, the stability of the first lens 320 is enhanced, and further, the system stability of the lens 300 is enhanced; on the other hand, the pressure of the light shielding sheet 350 for limiting the first lens 320 is reduced.

In an embodiment, referring to fig. 2, the inner wall of the lens barrel 310 is provided with a step-shaped boss 313, the lens barrel 300 further includes a second lens 330 disposed in the lens barrel 310, and the second lens 330 abuts against the boss 313 when being assembled into the lens barrel 310 from the image side space of the first lens 320. With the above design, the second lens 330 in the lens 300 and other lenses in the lens 300 that are located at the image side space of the second lens 330 can be directly assembled into the lens barrel 310 from the image side space of the lens 300. The first lens 320 can be assembled into the lens barrel 310 from the object space of the lens 300 after the second lens 330 and the other lenses are assembled into the lens barrel 310. Since the electronic device with the image capturing function provided by the present application eliminates the shielding portion 312 in the prior art, a position limiting structure, i.e., the boss 313, can be added to limit the position of each lens in the lens barrel 310. Meanwhile, in order to ensure the miniaturization of the lens 300, the position of the first lens 320 near the end 314 of the lens barrel 310 should be limited on the side of the first lens 320 far away from the end 314 of the lens barrel 310, so as to avoid increasing the axial length of the lens 300. Therefore, the bump 313 is designed to limit the position of each lens element in the image-side space of the first lens element 320, and when the lens elements in the image-side space of the first lens element 320 are assembled, the position of each lens element in the image-side space of the first lens element 320 is limited by the bump 313. At this point, each lens in the lens 300 completes the position limitation.

In one embodiment, referring to fig. 2, the side surface of the second lens element 330 is recessed inward to form a step-shaped limiting groove 331, and the limiting groove 331 and the boss 313 are mutually engaged. Through the above design, the stability between the second lens 330 and the lens barrel 310 is enhanced, and the system stability of the lens 300 is further improved.

The spacer ring 340 disposed between adjacent lenses in the lens 300 facilitates to pull apart the distance between adjacent lenses in the lens 300, so that each lens in the lens 300 can complete imaging.

In one embodiment, referring to fig. 2, the display device further includes a cover plate 100, and the cover plate 100 is attached to a surface of the display screen 200 away from the lens 300. The cover plate 100 serves to protect the display screen 200 and the lens 300 and to prevent dust from contaminating the lens 300.
