As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The conventional lens barrel is provided with a front wall at an object side end (i.e., a light incident end) thereof to shield light and support and limit the position of a lens in the lens barrel. However, the front wall is generally thick, and therefore, the thickness of the lens module is generally large without changing the arrangement of the optical imaging system in the lens module, so that when the lens is mounted on a mobile device with a photographing function, problems of an excessively large opening of a screen and a thick body of the mobile device are easily caused.
This application cancels the lens-barrel antetheca through the fixed mode that changes lens in the battery of lens to solve the too big and thicker problem of lens module thickness of mobile device screen trompil.
Referring to fig. 1 to 3, the present application provides a lens module 100, which includes a lens barrel 10 and a lens group 20 accommodated in the lens barrel 10, wherein the lens group 20 includes at least one lens.
The lens barrel 10 has an object side end 11 facing the object side, an image side end 12 facing the image side, and a light-passing hole 13 passing through the object side end 11 and the image side end 12 along the optical axis.
The lens group 20 includes a first lens 21, the first lens 21 is close to the object side, and has a first main body 211 for imaging, and a first fixing portion 212 disposed around the first main body 211, the first fixing portion 212 has a first surface 2122 connected to a wall of the light-passing hole. Further, the first body portion 211 at least includes an effective light-passing area of the first lens 21, and the first fixing portion 212 may be provided with a light-shielding element to achieve a light-shielding effect of the front wall of the original lens barrel, so as to adjust the amount of light entering the lens module 100.
The part of the first surface 2122 exposed to the light-passing hole 13 and the hole wall of the light-passing hole form a first connecting groove 15, and the first connecting groove 15 is filled with a colloid used for bonding the first lens 21 and the hole wall of the light-passing hole. Specifically, the first surface 2122 has a portion attached to the wall of the light-transmitting hole, and the portion of the first surface 2122 exposed to the light-transmitting hole 13 intersects with the wall of the light-transmitting hole, so that a receiving groove can be formed for dispensing. The supporting manner of the first lens 21 can be changed by providing the dispensing slot, i.e. the front wall of the conventional lens barrel can be eliminated, so as to greatly reduce the distance between the first fixing portion 212 and the object side end 11 on the optical axis. In particular, in the full-screen design process, the distance from the first fixing portion 212 to the object side end 11 on the optical axis is shortened, so that the first main body portion 211 of the first lens element 21 can be closer to the opening of the screen to obtain more light entering amount, in other words, under the condition that the lens has the same light entering amount requirement, the opening size of the screen corresponding to the lens module 100 of the present application can be smaller than that of the screen corresponding to the conventional lens module.

Furthermore, because the front wall of the lens cone does not exist, the first lens 21 can be closer to the opening on the screen to improve the light entering amount of the lens module 100, so that the size of the opening on the screen can be reduced, and a better overall screen effect can be realized; in addition, the thickness of the lens module 100 can be further reduced to make the body of the electronic photographing apparatus thin, thereby obtaining a better product design effect.
According to some embodiments of the invention, as shown in fig. 3, the first surface 2122 includes a first face 21221 obliquely arranged with respect to the clear hole wall, and a second face 21222 connected to the first face 21221 and contacting the clear hole wall, wherein the first face 21221 and the clear hole wall form the first connecting groove 15.

Specifically, the opening shape of the limiting groove 14 matches the outer peripheral shape of the light-shielding sheet 30, so that the light-shielding sheet 30 can be placed in the limiting groove 14. The limiting groove 14 is formed to limit the light shielding sheet 30, so that the positioning and the arrangement of the light shielding sheet 30 are facilitated, and the phenomenon that the light shielding sheet 30 is dislocated due to external vibration to affect the imaging effect of the lens module 100 can be avoided.
Further, with reference to fig. 3, the limiting groove 14 is a stepped groove and is opened at the hole wall near the object side end 11, and the periphery of the light shielding sheet 30 contacts with the groove wall of the limiting groove 14 facing the optical axis. Specifically, the depth of the step-shaped groove in the optical axis direction may be slightly greater than or equal to the thickness of the light-shielding sheet 30. The distance from the first lens 21 to the screen can be further reduced in the above manner, thereby reducing the aperture size of the screen.

Further, as shown in fig. 2 and fig. 3, the second fixing portion 222 includes a second object-side fixing surface 2221 facing the object side and a second image-side fixing surface 2223 facing the image side, the positioning portion 22210 is formed by extending the second object-side fixing surface 2221 toward the object side, the limiting portion 21230 is formed by recessing the first fixing portion 212 from a surface close to the second lens element 22 toward the object side, and the positioning portion 22210 is clamped in the limiting portion 21230. Specifically, the positioning portion 22210 may be configured as a protruding rib protruding toward the first fixing portion 212, the protruding rib has a positioning inclined surface inclined with respect to the second fixing portion 222, the limiting portion 21230 is configured as a groove matched with the protruding rib, the groove has a limiting inclined surface matched with the positioning inclined surface, and the protruding rib is engaged with the groove through the matching of the positioning inclined surface and the limiting inclined surface, so as to connect the first lens 21 and the second lens 22. The positioning portion 22210 is clamped to the limiting portion 21230 to provide a prestress for the second lens 22, so as to effectively improve the assembling strength between the first lens 21 and the second lens 22, and the positioning portion 22210 is disposed on the second object side fixing surface 2221 to further reduce the assembling thickness of the lens module 100.
According to some embodiments of the present invention, the second fixing portion 222 further includes a second surface 2222 connecting the second object side fixing surface 2221 and the second image side fixing surface 2223.

By providing the gap 130 between the second surface 2222 and the wall of the light-transmitting aperture, it is possible to avoid the second lens 22 being subjected to excessive radial forces, preventing a decrease in the coaxiality of the second lens 22 and the first lens 21.
Further, the lens barrel 10 has a protrusion 16 protruding from the wall of the light-passing hole, and the protrusion 16 contacts the second object side fixing surface 2221 to limit the position of the second lens 22. The second lens 22 can be limited in the optical axis direction by the protrusion 16, and the second lens 22 and the lens supported behind the second lens 22 can be axially supported.
Further, the protrusion 16 is also in contact with the first surface 2122, the first fixing portion 212 is partially abutted between the protrusion 16 and the positioning portion 22210, and a portion of the first surface 2122 exposed to the light passing hole and a side surface of the protrusion 16 away from the second fixing portion 222 form a first connecting groove 15.
