The lens elements comprise a glass lens element and a first plastic lens element, the first plastic lens element is arranged corresponding to the glass lens element, and the first plastic lens element is arranged in the plastic lens barrel. The plastic lens barrel has a first inner side surface and a first outer side surface, the first inner side surface surrounds the optical axis, the first plastic lens element is in contact with a first region of the first inner side surface, the first outer side surface is arranged corresponding to the first inner side surface and is further away from the first plastic lens element than the first inner side surface of the first plastic lens element. The frame component has a second inner side surface surrounding the optical axis and facing the first outer side surface, and the second inner side surface is in contact with a second portion of the first outer side surface. The gap is formed between the first outer side surface and the second inner side surface, the gap extends along the optical axis from the second region, and the gap corresponds to the first region. The imaging lens assembly further includes at least one first ring structure disposed on the first inner side surface, the first ring structure corresponds to the second region, and the first ring structure surrounds the optical axis and extends in a direction away from the frame component. The imaging lens assembly may simultaneously include the glass lens element and the first plastic lens element. Thus, the optical quality can be improved and the influence of the environment on the imaging lens assembly can be reduced. The first resin lens element is in contact with the resin lens barrel in the first region corresponding to the gap. This creates play for the expansion of the first lens element in a direction perpendicular to the optical axis in order to define the deformation direction of the first plastic lens element. In addition, the first ring structure corresponds to the second region, so that the mechanical strength of the second region can be improved. Thus, the influence of the environment on the size of the imaging lens assembly can be reduced.In particular, the frame component may be a socket, a frame, a socket or a lens holder, but the present disclosure is not limited thereto. In addition, the frame component is fixed to the plastic lens barrel by screw connection, adhesive, mechanical fitting, or a combination of a plurality of methods, but the present disclosure is not limited thereto.The imaging lens assembly may further include a first ring component forming the first ring structure, wherein the first ring component may be in contact with a third region of the first inner side surface. This allows the assembly flexibility to be increased.The hardness of the first ring component may be greater than the hardness of the plastic lens barrel. Thus, the axial deformation resistance of the plastic lens barrel can be improved to increase the shock resistance of the imaging lens assembly. In particular, the first ring component may be a metal part, a ceramic part, or a plastic part with glass fibers, but the present disclosure is not limited thereto.The first inner side surface and the first ring structure may be integrally formed. Thus, the need for parts can be reduced to simplify the assembly process.The frame component may comprise a protruding structure, the protruding structure extends in a direction near the optical axis, and one of the lens elements rests on the protruding structure. Thus, a holding function of the frame component for the lens elements can be additionally obtained to reduce the parts requirement.The hardness of the first frame component may be greater than the hardness of the plastic lens barrel. Thus, the size of the plastic lens barrel can be maintained in the event of environmental changes, so that the life of the imaging lens assembly can be prolonged. In particular, the frame component may be a metal part, a ceramic part, or a plastic part with glass fibers, but the present disclosure is not limited thereto.The second region does not need to overlap with the first region in a direction perpendicular to the optical axis. Thereby, the deformation margin of the first resin lens element in the direction perpendicular to the optical axis can be secured.In a section parallel to the optical axis, D for the lens diameter of the first resin lens element and T for the lens barrel thickness of the resin lens barrel in the first region can satisfy the following condition: 0.018≤T / D≤0.6.

Thus, sufficient support can be provided to prevent the resin lens element from being squeezed upon deformation.In the section parallel to the optical axis, W for the minimum width of the gap corresponding to the first range may satisfy the following condition: 0.0012 mm≤W≤0.24 mm. Thereby, with sufficient deformation margin, the mechanical strength can be increased to improve the production rate.The first ring structure is disposed in a third region of the first inner side surface and can satisfy the following condition in a section parallel to the optical axis with O for the overlap length of the third region with the second region and PBL for the length of the plastic lens barrel: 0.012≤O / PBL≤0.42.The number of the first ring structures may be greater than one. This is advantageous for securing the optical quality by further maintaining the distance between two of the lens elements.The imaging lens assembly may further include a holding component that holds the plastic lens barrel and the frame component, the holding component being disposed in the frame component, and the holding component being in contact with at least one of the lens elements and the plastic lens barrel. Thus, the cohesion of the frame component with the plastic lens barrel can be improved. In particular, the holding component may be a cover part, adhesive, or a combination of multiple components, or the holding component may be a bond formed by melting some components by heat or chemically, but the present disclosure is not limited thereto.The lens elements may also comprise a second plastic lens element and the first ring structure may be arranged between the second plastic lens element and the first plastic lens element. The second resin lens element may be in contact with the first inner side surface and the second resin lens element may correspond to the gap. Thus, the first ring structure can have a function of further maintaining the distance between two of the lens elements to increase the optical performance.The first ring structure may be arranged adjacent to the first plastic lens element. Thereby, the fitting relationship between the first resin lens element and the first ring structure can be additionally maintained to improve the mounting efficiency.The imaging lens assembly may further include a second ring structure disposed on the first inner side surface and the gap in the direction perpendicular to the optical axis, respectively, the second ring structure surrounding the optical axis and extending in a direction away from the gap. In a section parallel to the optical axis, the width of the gap corresponding to the second region may be smaller than the width of the gap corresponding to the first region, and with WN for the minimum width of the gap corresponding to the second ring structure, the following condition is satisfied: 0.004 mm≤WN≤0.05 mm. The gap corresponding to the second ring structure is narrower, so that the elongation margin of the lens elements can be obtained and the mechanical strength of the imaging lens assembly can be improved at the same time. This is advantageous for improving the stability of the entire optical system. In addition, WN for the minimum width of the gap corresponding to the second ring structure satisfies the following condition: 0.005 mm≤WN≤0.04 mm.The imaging lens assembly may further include a protruding structure disposed on the first outer side surface of the plastic lens barrel and the second ring structure, respectively, the protruding structure protruding in a direction away from the second ring structure, and the protruding structure maintaining the gap from the frame component. This is advantageous for regulating the deformation of the plastic lens barrel by improving the mechanical strength of the third region.The protruding structure may include a plurality of protruding sub-structures, and the protruding sub-structures are arranged at intervals. A gap closure on two sides of the protruding structure can be maintained after deformation. Thus, the deformation margin of the first resin lens element can be further maintained.Each of the foregoing features of the imaging lens assembly may be used in various combinations to achieve the respective effects.The present disclosure provides a camera module comprising the imaging lens assembly of the foregoing aspect and a component carrier, wherein the frame component of the imaging lens assembly is fixed in the component carrier. This is advantageous in preventing deformation of the plastic lens barrel during assembly to improve the assembly yield.

In addition, the first resin lens element is in contact with the resin lens barrel in the first region corresponding to the gap. This creates play for the expansion of the first plastic lens element in a direction perpendicular to the optical axis in order to define the deformation direction of the first plastic lens element. In addition, the width of the gap corresponding to the ring structure is smaller than the width of the gap corresponding to the first region, so that when the plastic lens barrel is squeezed by the frame component, the first plastic lens element is prevented from being impaired, so that the optical quality is maintained. In particular, the frame component may be a socket, a frame, a socket or a lens holder, but the present disclosure is not limited thereto.The imaging lens assembly may further include a protruding structure disposed on the first outer side surface of the plastic lens barrel and the ring structure, respectively, the protruding structure protruding in a direction away from the ring structure, and the protruding structure maintaining the gap from the frame component.

Thereby, with sufficient deformation margin, the mechanical strength can be increased to improve the production rate.In a section parallel to the optical axis, the second region does not have to overlap with the first region.
