Description

Camera Module {CARMERA MOUDULE} The present disclosure relates to a camera module. Driven by remarkable advancements in information and communication technology and semiconductor technology, the adoption and use of electronic devices are increasing rapidly. These devices are no longer confined to their traditional domains but are trending toward providing a wide range of convergent functions. Recently, cameras have been standardly adopted in portable electronic devices such as smartphones, tablet PCs, and laptop computers, and these cameras are equipped with features such as autofocus (AF), image stabilization, and zoom. Furthermore, heavy camera modules using large sensors are being developed for high-quality photos, and the addition of aperture functions has further increased the weight of the camera modules. Consequently, there is a problem where the lens barrel impacts the IR filter upon dropping the camera module, causing frequent cracks in the IR filter. FIG. 1 is a perspective view of a camera module according to one embodiment. FIG. 2 is an exploded perspective view of a camera module according to one embodiment. FIG. 3 is a simplified cross-sectional view of a camera module according to one embodiment. FIG. 4 is a plan view of a part of a camera module according to one embodiment. FIG. 5 is a perspective view of a housing of a camera module according to one embodiment. Figure 6 is a diagram showing the impact force simulation results of the comparative example and the example. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the invention. In order to clearly explain the invention in the drawings, parts unrelated to the explanation have been omitted, and the same reference numerals have been used for identical or similar components throughout the specification. Furthermore, in the attached drawings, some components may be exaggerated, omitted, or schematically depicted, and the size of each component does not entirely reflect its actual size. The attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that all modifications, equivalents, and substitutions included within the concept and technical scope of the present invention are included. Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. Furthermore, when it is said that a part, such as a layer, membrane, region, or plate, is "on" or "on" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when it is said that a part is "directly above" another part, it means that there is no other part in between. Also, saying that a part is "on" or "on" a reference part means that it is located above or below the reference part, and does not necessarily mean that it is located "on" or "on" in the direction opposite to gravity. Throughout the specification, terms such as “comprising” or “having” are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Accordingly, when a part is said to “comprising” a certain component, unless specifically stated otherwise, this means that it may include additional components rather than excluding other components. Additionally, throughout the specification, "planar" means when the subject part is viewed from above, and "cross-sectional" means when the cross-section obtained by vertically cutting the subject part is viewed from the side. Throughout the specification, when a part is described as being "coupled" with another part, this includes not only cases where they are "directly or physically coupled," but also cases where they are "indirectly or non-contact coupled" with another element in between. Furthermore, throughout the specification, when the term "connected" is used, it does not mean only that two or more components are directly connected, but may also mean that two or more components are indirectly connected through other components, that they are connected not only physically but also electrically, or that they are a single unit although referred to by different names depending on their location or function. With reference to FIGS. 1 to 3, a camera module (10) according to one embodiment will be described. FIG. 1 is a perspective view of a camera modul
