Example one
Please refer to fig. 1, which is a schematic structural diagram of a lens module 100 according to an embodiment of the present invention, the lens module 100 includes a lens barrel 10, a lens assembly and a light blocking cover 12, the lens barrel 10 has an object side end 10a and an image side end 10b, the lens assembly includes a plurality of lenses, the plurality of lenses are sequentially mounted on the lens barrel 10 from the object side end 10a to the image side end 10b, the lens at the object side end 10a is a first lens 11, the first lens 11 has an optical portion 11a, the optical portion 11a at least partially protrudes from the object side end 10a, the light blocking cover 12 includes a cover portion 121 and a connecting portion 122, the cover portion 121 covers the optical portion 11a, the cover portion 121 has a stop hole 12a, the stop hole 12a is used for light passing, and the connecting portion 122 is connected to the cover portion 121 and the lens barrel 10.
Fig. 1 only shows the first lens 11, and the number and the structure of the remaining lenses can be designed according to actual requirements, and therefore, are not shown in fig. 1 one by one.
As shown in fig. 2, a lens module 100 'of the related art generally employs an integrated lens barrel 10', a lens 11 'is installed through the integrated lens barrel 10', and the lens 11 'is wrapped by a partial structure of the integrated lens barrel 10' to prevent light leakage. Because the partial structure that the integral type lens cone 10 ' is used for wrapping up lens 11 ' needs to be designed for less thickness to make the lens module that has this integral type lens cone 10 ' can be applied to the camera of bang screen or full screen cell-phone, this leads to the shaping degree of difficulty of the partial structure that is used for wrapping up lens 11 ' of integral type lens cone 10 ' to be higher.
Therefore, in the present embodiment, the lens assemblies are sequentially mounted on the lens barrel 10 from the object side end 10a to the image side end 10b, the light blocking cover 12 is connected to the lens barrel 10 and covers the optical portion 11a of the first lens 11, so that the light blocking cover 12 and the lens barrel 10 can be separately formed, and the difficulty in forming can be reduced on the premise of ensuring that the thickness of the light blocking cover 12 is small.
In addition, as shown in fig. 2, when the integral lens barrel 10 'of the lens module 100' of the related art is formed, a sharp corner 10a 'is formed at the aperture hole, and the sharp corner 10 a' is easy to cause severe spike-shaped stray light, and is difficult to improve, thereby affecting the imaging quality. While the molding difficulty of the light blocking cover 12 is reduced, the light blocking cover 12 can avoid the sharp corner through independent processing molding, so that serious spike-shaped stray light is avoided, and the imaging quality is guaranteed.
In addition, in the present embodiment, the cover body portion 121 is covered on the optical portion 11a, so as to prevent light leakage and prevent stray light from entering the first lens 11, the connecting portion 122 is connected to the cover body portion 121 and the lens barrel 10 to fix the position of the cover body portion 121 relative to the lens barrel 10, and the occurrence of light shielding failure of the cover body portion 121 on the optical portion 11a due to relative position deviation of the cover body portion 121 and the first lens 11 is avoided.
Illustratively, the light-blocking cover 12 has a thickness t ≦ 0.05 mm. It can be understood that, as shown in fig. 2, the head diameter D 'of the lens module 100' of the related art is a '+ 2 t', where a 'is the aspheric diameter of the lens 11', t 'is the thickness of the partial structure of the lens barrel 10' for wrapping the lens 11 ', and 0.3mm ≦ t' ≦ 0.5 mm. As shown in fig. 1, the head diameter D of the lens module 100 of the present embodiment is equal to a +2t, where a is the diameter of the optical portion 11a of the first lens 11, and is equivalent to the aspheric diameter a' of the lens module 100 of the related art. That is to say, the thickness t of the light blocking cover 12 is at least 0.25mm smaller than t ', so that the diameter D of the head of the lens module 100 of this embodiment is reduced by at least 0.5mm compared with the diameter D' of the head of the lens module 100 of the related art, and the overall size of the lens module 100 is smaller, which is beneficial to the miniaturization design of electronic equipment and improves the screen occupation ratio of the electronic equipment.
In this embodiment, the light-blocking cover 12 is made of opaque material, or the surface of the light-blocking cover 12 is coated with a light-blocking layer. It can be understood that the present embodiment provides a plurality of different ways to realize that the light blocking cover 12 can prevent light leakage, and prevent stray light from entering the first lens 11, which can be selected according to practical situations to meet different use requirements.
Alternatively, the light-blocking cover 12 may be made of metal. For example, the metal material may be copper, aluminum, stainless steel, etc. By using a metal material, the strength of the light blocking cover 12 can be improved, and the molding is more stable. In some other embodiments, the material of the light blocking cover 12 may also be a rigid plastic, which is not particularly limited in this embodiment.
Further, the lens barrel 10 includes a main body 101 and a bending portion 102, the main body 101 has an object side end 10a and an image side end 10b, the bending portion 102 is disposed at the object side end 10a, and the connecting portion 122 is compressed between the main body 101 and the bending portion 102. It can be understood that, by pressing the connecting portion 122 between the main body 101 and the bending portion 102, the connecting strength between the light blocking cover 12 and the lens barrel 10 is high, and the light blocking cover is not easily separated from the lens barrel 10, so that the lens module 100 functions stably and reliably.
Specifically, the bending portion 102 is used for being bent relative to the main body 101 during heating to form a mounting groove 10c with the main body 101, and the connecting portion 122 at least partially extends into the mounting groove 10c to be pressed between the main body 101 and the bending portion 102. It can be understood that, when the light-blocking cover 12 is assembled with the lens barrel 10, the connecting portion 122 of the light-blocking cover 12 is placed on the main body 101 from the object-side end 10a of the main body 101, the bending portion 102 is heated to reach a predetermined temperature, the bending portion 102 can be bent relative to the main body 101 at the predetermined temperature, so that the bending portion 102 is bent relative to the main body 101 to press the connecting portion 122 against the main body 101, and after the bending portion 102 is cooled, the connecting portion 122 can be firmly located in the mounting groove 10c between the bending portion 102 and the main body 101, thereby achieving the assembly of the light-blocking cover 12 and the lens barrel 10. That is, in the present application, the light-blocking cover 12 and the lens barrel 10 are assembled from the object-side end 10a, which does not affect the assembly of the lens assembly and the lens barrel 10, the tolerance can be reduced, the thermal stability is good, and the lens module 100 is difficult to reach the predetermined temperature during normal use, so that the bending portion 102 cannot be bent relative to the main body 101, that is, the connecting portion 122 cannot be separated from the mounting groove 10c, and the connection strength between the light-blocking cover 12 and the lens barrel 10 is high.
Illustratively, the mounting groove 10c is a straight groove or an L-shaped groove, and the shape of the portion of the connecting portion 122 extending into the mounting groove 10c is adapted to the shape of the mounting groove 10 c. It can be understood that the mounting groove 10c is designed in a straight shape, and the structure of the connecting portion 122 is relatively simple, so that the difficulty in forming the light blocking cover 12 can be reduced. The mounting groove 10c is designed in an L shape, and the difficulty of separating the connecting portion 122 from the mounting groove 10c is high, so that the connecting strength between the light blocking cover 12 and the lens barrel 10 can be improved. That is, the present embodiment provides a plurality of mounting grooves 10c and the connecting portion 122 with different shapes, which can be selected according to actual situations to meet different use requirements.
As an alternative embodiment, as shown in fig. 1, the mounting groove 10c is disposed on the inner wall of the object side end 10a, and the opening of the mounting groove 10c faces the optical axis a of the lens barrel 10.

As shown in fig. 1, after the bending portion 102 is heated and bent, the mounting groove 10c is formed between the bending portion 102 and the main body 101, and at this time, the connecting portion 122 is pressed against the bending portion 102 and the main body 101, so as to assemble the light blocking cover 12 and the lens barrel 10.
As another alternative embodiment, as shown in fig. 4 and fig. 5, the mounting groove 10c is disposed on an end surface of the object-side end 10a, the connecting portion 122 includes a first extending portion 122a and a second extending portion 122b connected to the first extending portion 122a, the first extending portion 122a extends from the cover portion 121 to an end surface of the object-side end 10a in a direction away from the optical axis a of the lens barrel 10, and the second extending portion 122b extends into the mounting groove 10c to be compressed between the bending portion 102 and the main body portion 101. It is understood that, as shown in fig. 6 or fig. 7, when the bending portion 102 is not heated and bent, the mounting groove 10c is not formed between the bending portion 102 and the main body 101, and at this time, the connecting portion 122 can be placed on the main body 101 from the object side end 10a of the main body 101. As shown in fig. 4 or fig. 5, after the bending portion 102 is heated and bent, the mounting groove 10c is formed between the bending portion 102 and the main body 101, and at this time, the second extending portion 122b is pressed against the bending portion 102 and the main body 101, so as to assemble the light blocking cover 12 and the lens barrel 10.
In the lens module 100 according to the first embodiment of the present invention, the lens assembly is sequentially mounted along the object side end 10a toward the image side end 10b through the lens barrel 10, the first lens 11 of the lens assembly has an optical portion 11a, and at least a portion of the optical portion 11a is located outside an opening of the object side end 10a and is covered on the optical portion 11a by the light blocking cover 12 connected to the lens barrel 10 to prevent light leakage. The light blocking cover 12 and the lens barrel 10 can be separately processed and molded, and the molding difficulty is low.

Please refer to fig. 8, which is a schematic structural diagram of a lens module 200 according to the second embodiment of the present invention, the lens module 200 includes a lens barrel 20, a lens assembly and a light blocking cover 22, the lens barrel 20 has an object-side end 20a and an image-side end 20b, the lens assembly includes a plurality of lenses, the lenses are sequentially mounted on the lens barrel 20 from the object-side end 20a to the image-side end 20b, the lens at the object-side end 20a is a first lens 21, the first lens 21 has an optical portion 21a, the optical portion 21a is at least partially located outside an opening of the object-side end 20a, the light blocking cover 22 is connected to the lens barrel 20 and covers the optical portion 21a, the light blocking cover 22 is provided with a diaphragm hole 22a corresponding to the optical portion 21a, and the diaphragm hole 22a is used for light to pass through.
The lens module 200 of the second embodiment is different from the lens module 100 of the first embodiment in the connection manner of the light blocking cover 22 and the lens barrel 20, and the second embodiment is mainly described with respect to the main differences, and other parts that are the same as those of the first embodiment are not repeated, which can be referred to in the description of the first embodiment.
In the present embodiment, the connecting portion 222 of the light blocking cover 22 is adhered to the lens barrel 20. It can be understood that the connection portion 222 is connected to the lens barrel 20 by bonding, so as to assemble the light blocking cover 22 and the lens barrel 20, and the assembly method is simple in process, low in assembly difficulty, high in assembly efficiency, and capable of adapting to mass production of the lens module 200.

It can be understood that, by receiving part of the connecting portion 222 in the groove 20c, and the connecting portion 222 being lower than the end surface of the object side 20a, the overall length of the lens module 200 can be reduced, which is beneficial to miniaturization design.
As another alternative, as shown in fig. 9 and 10, a notch 20d is formed along a circumference of the object side end 20a of the lens barrel 20, and the connecting portion 222 is adhered to the notch 20 d. It can be understood that, by forming the notch 20d on the outer side wall of the object-side end 20a of the lens barrel 20, the lens barrel 20 is prevented from being affected by the structure thereof during dispensing, and the difficulty of dispensing is reduced. Optionally, the notch 20d may be formed by cutting a material of the lens barrel 20 to form the notch 20d, or the notch 20d may be formed by providing a protrusion on the lens barrel 20 to form the notch 20d around the protrusion, which is not limited in this embodiment.
