[0041] Please refer to Figures 1 to 13 The adapter structure comprises an adapter ring 10 and an adapter fitting 20, the adapter ring 10 is used for connecting a filter, and the adapter fitting 20 is used for connecting a shell structure sleeved on a camera lens, and the adapter ring 10 is characterized in that:

[0042] Part of the structure of the adapter ring 10 is enclosed to form an adapter part 10a, the adapter part 10a is provided with a plug-in part, and the outer peripheral wall of the adapter fitting 20 is provided with a plug-in fitting part; the adapter fitting 20 can be connected to the adapter ring 10 through the sliding opening 10b of the adapter part 10a, so that the plug-in fitting part is slidably connected to the plug-in part.

[0043] In the technical scheme of the present application, the adapter structure comprises an adapter ring 10 and an adapter fitting 20, the adapter ring 10 is detachably connected to the adapter fitting 20, the adapter ring 10 is used for connecting a filter, wherein the adapter ring 10 is enclosed to form an adapter part 10a, the adapter ring 10 can be slid out relative to the adapter fitting 20 through the sliding opening 10b of the adapter part 10a, in the process of sliding out of the adapter ring 10 relative to the adapter fitting 20, the plug-in part is separated from the plug-in fitting part, so as to achieve the purpose of quickly detaching the adapter ring 10 from the adapter fitting 20; and when the adapter structure is in an assembled state, because of the constraint effect between the plug-in part and the plug-in fitting part, the loosening problem between the adapter ring 10 and the adapter fitting 20 can be effectively prevented, so as to guarantee the stability of the filter to the lens.

[0044] First of all, the adapter structure proposed in the present application can be applied to mobile terminals with shooting functions, such as smart phones, tablet computers and single-lens reflex cameras, etc. A shell structure (such as a protective shell) is sleeved on the mobile terminal. The shell structure can be a mobile phone shell, a mobile phone rabbit cage, a camera shell, a camera rabbit cage, or a protective shell for a tablet computer. The adapter structure is arranged at the mounting position of the lens corresponding to the shell structure by adhesive or one-piece forming, so that when the filter is mounted on the adapter ring 10, the lens corresponds to the filter, and the desired shooting effect is achieved.

[0045] In this embodiment, the adapter ring 10 includes an integral connecting upper portion 110 and a connecting lower portion 120. Figure 4 As shown, the cross section of the connecting upper portion 110 is circular, which encloses a receiving groove. The receiving groove can be provided with a threaded structure or a magnetic structure to achieve fixed connection of the filter. The connecting lower portion 120 is made of plastic material, as shown in FIG. Figure 5 As shown, the connecting lower part 120 is enclosed to form the adapter part 10a, and one side of the adapter part 10a is opened to form the adapter part 10a to form an open limiting structure. The sliding opening 10b formed by the adapter part 10a can be used for the adapter fitting 20 to pass back and forth, and the other side is closed to have the function of travel stop limiting. The layered arrangement of the connecting upper part 110 and the connecting lower part 120 effectively avoids position interference between the filter and the protective shell, thereby reducing the shooting quality; in order to achieve relative sliding between the adapter ring 10 and the adapter fitting 20, the groove wall of the adapter part 10a can be an inner peripheral wall or an end wall facing away from the connecting upper part 110. A plug-in part is provided, and the plug-in part can be a solid bone-inserting structure that is arranged in an entire section or at intervals, or a virtual limiting card groove that is arranged around or at intervals. The structure is not limited here; it can be understood that the adapter portion 10a is a virtual structure formed by connecting the lower portion 120 (solid structure), and the adapter portion 10a can be a groove shape with one end open and the other end closed, or, the adapter portion 10a can be a channel shape with both ends open. Furthermore, it can be an open structure at one end for achieving sliding fit between the adapter ring 10 and the adapter mating part 20, and a special-shaped structure with a small opening on the basis of a closed setting to act as a stopper on the other end. Based on the above three situations, the inventive concept of the present utility model is that no matter what shape the adapter portion 10a is, it only needs to have an opening for the adapter mating part 20 to slide in or out, so as to achieve sliding fit between the adapter ring 10 and the adapter mating part 20. The specific shape is explained below.

[0046] The adapter fitting piece 20 is connected to the shell structure at the lens of the mobile terminal on one side, and is fixedly connected to the shell structure by means of an adhesive process or an integrated molding process. On the other side, the adapter fitting piece 20 is connected to the adapter ring 10 in a sliding and detachable manner by means of the plug-in fitting part. Specifically, the shape and size of the adapter fitting piece 20 are adapted to the connection lower part 120, so as to improve the connection stability between the adapter fitting piece 20 and the adapter ring 10. The specific design of the plug-in fitting part can be adjusted adaptively, for example, when the inner circumferential wall of the adapter part 10a is provided with a solid plug-in bone structure, the plug-in fitting part is an integral type limiting clamping groove 20a structure arranged along the outer circumferential wall of the adapter fitting piece 20. During the relative sliding process between the adapter fitting piece 20 and the adapter ring 10, the plug-in fitting part is connected to the plug-in part in a sliding manner. Alternatively, when the inner circumferential wall of the adapter part 10a is provided with a virtual limiting clamping groove structure, the plug-in fitting part is an integral type solid plug-in bone structure arranged along the outer circumferential wall of the adapter fitting piece 20. In this way, the plug-in fitting part can also be connected to the plug-in part in a sliding manner during the relative sliding process between the adapter fitting piece 20 and the adapter ring 10. Therefore, the plug-in part and the plug-in fitting part are replaced, and the specific design is not limited.

[0047] In another embodiment, the adapter ring 10 comprises an integrated connection upper part 110 and a connection lower part 120. The connection upper part 110 is circular in cross section and encloses a receiving groove. The receiving groove can be provided with a threaded structure or a magnetic attraction structure to achieve fixed connection of the filter. The connection lower part 120 is arranged on the side of the connection upper part 110 away from the receiving groove and comprises two oppositely arranged plastic ribs. Each plastic rib is provided with a plug-in part. The two plastic ribs are oppositely arranged to form a plug-in channel with sliding openings at both ends. The plug-in channel constitutes an adapter part 10a required by the filter. In this way, the sliding connection between the adapter ring 10 and the adapter fitting piece 20 can also be achieved through the plug-in channel. When the adapter ring 10 is connected to the adapter fitting piece 20 in a sliding manner, the plug-in fitting part and the plug-in part are connected in a plug-in manner. Further, one end of each plastic rib is bent to form a bent section. The two bent sections extend towards each other. In this way, the adapter part forms a sliding stop structure. When the adapter ring 10 slides a certain distance relative to the adapter fitting piece 20, the adapter fitting piece 20 abuts against the bent section, thereby achieving sliding stop. It can be understood that the two bent sections can extend to be connected to each other. In this way, one end of the plug-in channel forms a closed structure. The two bent sections can also extend by a certain length without being connected to each other, which is not limited herein.

[0048] In an embodiment of the present application, as shown in Figure 5 , Figure 6 , Figure 9 and Figure 12As shown, the adapter part 10a encloses a notch slot, and the notch slot forms a sliding opening 10b; the plug-in part 100 is a first plug bone 101 and a second plug bone 102, and the first plug bone 101 and the second plug bone 102 protrude in the direction of the inner slot wall 10c of the notch slot or protrude in the direction of the outer slot wall 10d of the notch slot; the plug-in matching part is a limiting slot 20a, and when the plug-in matching part is slidably connected to the plug-in part 100, the first plug bone 101 and the second plug bone 102 are respectively inserted into a limiting slot 20a.

[0049] In the embodiment, the adapter part 10a encloses a notch slot, one end of the notch slot forms a sliding opening, and the other end is closed. The plug-in part is a limiting plug bone structure, and the limiting plug bone structure includes a first plug bone 101 and a second plug bone 102. The first plug bone 101 and the second plug bone 102 are both straight segments, and are arranged to extend in the sliding direction of the adapter ring 10 towards or away from the adapter matching part 20 along the inner slot wall 10c of the adapter ring 10. In this way, a smaller force can be applied to the adapter ring 10 to disassemble the adapter ring 10. It can be understood that the first plug bone 101 and the second plug bone 102 can be arranged in a same side of the inner slot wall of the adapter part 10a or arranged in different sides, which is not limited herein. Further, the plug-in matching part is a limiting slot 20a adapted to the first plug bone 101 and the second plug bone 102, and the limiting slot 20a is adaptively arranged according to the positions of the first plug bone 101 and the second plug bone 102 to achieve the sliding connection of the adapter ring 10 to the adapter matching part 20. In another embodiment, the adapter part 10a encloses a notch slot, one end of the notch slot forms a sliding opening, and the other end is closed. The plug-in part is a limiting plug bone structure, and the limiting plug bone structure includes a first plug bone 101 and a second plug bone 102. The first plug bone 101 and the second plug bone 102 are both straight segments, and are arranged to extend in the sliding direction of the adapter ring 10 towards or away from the adapter matching part 20 along the outer slot wall 10d of the adapter ring 10. At this time, the adapter matching part 20 is provided with a plastic material insertion profiled channel for enclosing the adapter part 10a. It can be understood that the profiled channel avoids the lens hole structure on the adapter matching part to avoid positional interference between the two. At this time, the profiled channel is provided with a limiting slot 20a. In this way, when the adapter ring 10 is slidably inserted into the adapter matching part 20, the plastic material is inserted into the profiled channel, and the first plug bone 101 and the second plug bone 102 are inserted into the corresponding limiting slot 20a.

[0050] In an embodiment of the present application, as shown in Figure 5 、 Figure 6 、 Figure 11 and Figure 12 , the first plug bone 101 and the second plug bone 102 are respectively located on opposite sides of the inner slot wall 10c of the adapter part 10a, and the first plug bone 101 and the second plug bone 102 protrude towards the inner slot wall of the adapter part 10a.

[0051] In the embodiment, in order to improve the connection stability between the adapter ring 10 and the adapter fitting 20, the first insertion bone 101 and the second insertion bone 102 are respectively located on opposite sides of the inner groove wall 10c of the adapter portion 10a, at this time, the opposite sides of the outer peripheral wall of the adapter fitting 20 are provided with a limiting clamping groove 20a, so that each insertion bone can be inserted into a limiting clamping groove 20a; further, the first insertion bone 101 and the second insertion bone 102 protrude from the inner groove wall of the adapter portion 10a, when the adapter structure is in the assembled state, the first connecting portion can only slide along the length direction of the first insertion bone 101 or the second insertion bone 102, so that the first connecting portion and the second connecting portion have two constraint forces formed in the vertical length direction (for example, defining the length direction as the X-axis direction in the spatial coordinate system, at this time, the first connecting portion and the second connecting portion have constraint forces along the Y-axis and Z-axis directions), greatly improving the connection stability between the adapter ring 10 and the adapter fitting 20, at the same time, the first insertion bone 101 and the second insertion bone 102 gradually decrease in cross section from one end of the inner groove wall of the limiting clamping groove 20a to the end away from the inner groove wall of the limiting clamping groove 20a, so that the first insertion bone 101 and the second insertion bone 102 are convenient to insert into the corresponding limiting clamping groove 20a.
