Description

Camera module and electronic device including the same Cross Reference to Related Applications The present application claims the benefit of priority from korean patent application No. 10-2020-01101074 filed on 9 months 16 in 2020, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field The present disclosure relates to a camera module that can prevent a lens from being separated from a lens barrel. Background The camera module includes a lens barrel configured to accommodate a plurality of lenses therein. The lens barrel has an inner space in which lenses may be sequentially arranged in ascending order of size. For example, the inner space of the lens barrel may be gradually widened from one side thereof toward the other side thereof to sequentially accommodate therein the first lens having the smallest size and the lens having the largest size. Since the other side of the lens barrel is wide enough to accommodate the largest lens, the lens can be easily separated from the lens barrel. Therefore, in order to prevent lens separation, the outermost lens is fixed by inserting a press-fit ring to the other side of the lens barrel or applying an adhesive to the other side of the lens barrel. However, as the number of lenses arranged in the lens barrel gradually increases, fixing the lenses by press-fitting the rings and the adhesive becomes difficult. The above information is presented merely as background information to aid in the understanding of the present disclosure. No determination is made, nor an assertion is made, as to whether any of the above may be used as prior art with respect to the present disclosure. Disclosure of Invention This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. In one general aspect, a camera module includes a first lens barrel including a first support portion that supports a lens accommodated in the first lens barrel on an object side of the first lens barrel, and a second lens barrel including a second support portion that supports a lens accommodated in the second lens barrel on an image side of the second lens barrel, wherein the first lens barrel and the second lens barrel are configured to be coupled to each other by a protrusion and a groove. The camera module may further include a first lens group disposed in the first lens barrel, and a second lens group disposed in the second lens barrel. The first lens group may include a plurality of lenses. The maximum diameter of the lenses constituting the first lens group may be smaller than the maximum diameter of the lenses constituting the second lens group. The first lens barrel may include a stepped portion for supporting the lenses of the first lens group in the first accommodation space of the first lens barrel. The camera module may further include a gap maintaining member disposed between the first lens accommodated in the first lens barrel and the second lens accommodated in the second lens barrel when the first lens barrel and the second lens barrel are coupled to each other by the protrusion and the groove. The maximum diameter of the gap retaining member may be larger than the maximum diameter of the second lens. When the first lens barrel and the second lens barrel are coupled to each other by the protrusion and the groove, a space in which an adhesive is to be filled may be located between the protrusion and the groove. The protrusion and the recess may include threads to mate with each other. The electronic apparatus may include a camera module and a surface on which the camera module is mounted, the camera module further including an image sensor configured to convert an optical signal incident through lenses of the first lens barrel and the second lens barrel into an electrical signal when the first lens barrel and the second lens barrel are coupled to each other by the protrusion and the groove.
