[0054] Please refer to Figures 1 to 6 The inner peripheral wall of the adapter ring 10 is provided with a first clamping portion, and the outer peripheral wall of the adapter fitting 20 is provided with a second clamping portion adapted to the first clamping portion;

[0055] Wherein, the transfer structure has an assembled state and a disassembled state;

[0056] In the assembled state, the first clamping portion and the second clamping portion are clamped and fixed;

[0057] In the disassembled state, the first clamping portion is disengaged from the second clamping portion;

[0058] The adapter ring 10 is rotatably engaged with the adapter mating part 20, and the first clamping part is slidably engaged with the second clamping part. When the adapter ring 10 rotates relative to the adapter mating part 20, the first clamping part moves relative to the second clamping part, so that the adapter structure can switch between the assembled state and the disassembled state.

[0059] In the technical solution of the present invention, the adapter structure includes an adapter ring 10 and an adapter fitting 20, the adapter ring 10 is used to connect the filter, wherein the inner peripheral wall of the adapter ring 10 is provided with a first clamping portion, and the outer peripheral wall of the adapter fitting 20 is provided with a second clamping portion adapted to the first clamping portion. When the adapter fitting 20 is screwed into the adapter ring 10 along a first rotation direction, the first clamping portion clamps the second clamping portion, so that the adapter ring 10 is fixedly connected to the adapter fitting 20, and then the adapter ring 10 is screwed out along a second rotation direction opposite to the first rotation direction, so that the first clamping portion is disengaged from the second clamping portion. Through different rotation directions, the adapter structure can be quickly switched back and forth between the assembled state and the disassembled state; and when the adapter structure is in the assembled state, due to the constraint effect between the first clamping portion and the second clamping portion, the loosening problem between the adapter ring 10 and the adapter fitting 20 can be effectively prevented, thereby ensuring the stability of the filter alignment lens.

[0060] First of all, it needs to be explained that the adapter structure proposed in the present invention can be applied to mobile terminals with shooting functions, such as smart phones, tablet computers and SLR cameras. A shell structure (such as a protective case) is provided on the mobile terminal, and the adapter structure is arranged at the installation position of the lens corresponding to the protective case by bonding or integral molding, so that when the filter is installed on the adapter ring 10, the lens corresponds to the filter, and the required shooting effect is achieved.

[0061] In this embodiment, the adapter ring 10 includes an integral annular upper part and an annular lower part, wherein the cross-section of the annular upper part is circular, which encloses a receiving groove, and the receiving groove can be provided with a threaded structure or a magnetic structure to achieve fixed connection of the filter; the inner circumferential wall of the annular lower part is provided with a first clamping part, and the first clamping part can be a virtual groove structure or a solid convex strip structure. Furthermore, the first clamping part can also be an engaging tooth structure, and the engaging tooth structure extends along the direction from the annular lower part at one end of the annular lower part connected to the annular upper part to the end away from the annular upper part to form a first clamping part, which is not limited here. The layered arrangement of the annular upper part and the annular lower part effectively avoids position interference between the filter and the protective shell, thereby reducing the shooting quality.

[0062] The cross-sectional shape of the adapter fitting 20 is a circle that fits the adapter ring 10, and its overall cross-sectional area is smaller than the adapter ring 10. In this way, the adapter ring 10 can completely surround the outer peripheral wall of the adapter fitting 20, so as to reduce the distance between the adapter ring 10 and the shell structure, compress the occupied space, and minimize the distance between the filter and the lens to improve the shooting effect; one side of the adapter fitting 20 is used to connect to the shell structure at the lens of the mobile terminal, and can be fixedly connected to the shell structure by a bonding process or an integrated molding process, and the other side is provided with a second clamping part that fits the first clamping part. The second clamping part can be set to different forms of the first clamping part. For example, when the first clamping part is a virtual groove-shaped structure, the second clamping part provided on the outer peripheral wall of the adapter fitting 20 is a solid convex strip structure. In this way, the user rotates the adapter ring 10 , that is, the virtual groove-shaped structure and the solid convex strip structure can be engaged with each other, so that the adapter structure enters the assembled state. Similarly, the adapter ring 10 is rotated in the opposite direction, and the first clamping part moves relative to the second clamping part. After rotating a certain angle, the first clamping part is disengaged from the second clamping part, so that the adapter structure enters the disassembled state. Of course, when the first clamping part is a solid convex strip structure, the second clamping part is a virtual groove-shaped structure. The corresponding matching relationship is shown above and is not explained here. It can be understood that the solid convex strip structure and the virtual groove-shaped structure can be replaced with each other. Therefore, the first clamping part and the second clamping part are not specifically limited here; in another embodiment, the first clamping part can be a meshing tooth structure, and the second clamping part is also a meshing tooth structure, so that the first clamping part can be meshed and connected to the second clamping part, thereby realizing the rotatable and detachable connection of the adapter ring 10 to the adapter mating part 20.

[0063] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, the first clamping portion is the limiting insert arm 100, and the second clamping portion is the limiting slot 20a. Both the limiting insert arm 100 and the limiting slot 20a are extended along the rotation direction.

[0064] In this embodiment, the first clamping portion is a limiting plug arm 100, which protrudes from the inner peripheral wall of the annular lower portion, and the second clamping portion is a limiting slot 20a. In order to enable the first clamping portion to surround and cover the adapter 20, a notch structure is formed at the end of the adapter 20 away from the shell structure. The notch structure is connected to the limiting slot 20a and can allow the limiting plug arm 100 to pass through. Specifically, the user first aligns the limiting plug arm 100 with the notch structure, and then moves the adapter ring 10 downward and abuts the shell. body structure, at this time, the limiting arm 100 aligns with the limiting slot 20a through the notch structure, and then the adapter ring 10 is rotated to make the limiting arm 100 enter and abut the limiting slot 20a; further, the limiting arm 100 and the limiting slot 20a are both extended along the rotation direction, thereby increasing the contact area between the limiting arm 100 and the limiting slot 20a, improving the connection reliability between the adapter ring 10 and the adapter mating part 20, and reducing the looseness problem between the two, thereby affecting the shooting effect.

[0065] In one embodiment of the present invention, the adapter ring 10 is provided with a plurality of limiting arms 100, which are arranged at intervals along the inner wall of the adapter ring 10; the outer wall of the adapter fitting 20 is provided with a plurality of limiting slots 20a, and each limiting arm 100 is inserted into a limiting slot 20a.

[0066] In this embodiment, in order to further improve the connection reliability between the adapter ring 10 and the adapter fitting 20, the adapter ring 10 is provided with at least two limiting arms 100. Figures 2 to 6 Three limiting arms 100 are arranged at intervals along the inner wall of the adapter ring 10. At the same time, a corresponding number of limiting slots 20a are provided on the outer wall of the adapter mating part 20. By rotating the adapter ring 10, each limiting arm 100 is inserted into a limiting slot 20a. In this way, multiple locking areas are formed between the adapter ring 10 and the adapter mating part 20, which effectively prevents the adapter structure from loosening.

[0067] In one embodiment of the present invention, a stopper 201 is provided at one end of the limiting slot 20 a . In the assembled state, the stopper 201 abuts against the limiting insert arm 100 to stop the limiting adapter ring 10 .

[0068] In this embodiment, in order to limit the maximum rotational stroke of the adapter ring 10, a stop portion 201 is provided at one end of the limit slot 20a, and the stop portion 201 blocks the outlet end of the limit slot 20a. In this way, when the limit arm 100 moves a certain distance in the limit slot 20a, the stop portion 201 abuts against the limit arm 100 to stop the limit adapter ring 10 from continuing to rotate. At this time, it indicates that the limit arm 100 has completely entered the limit slot 20a and the adapter structure is in an assembled state.

[0069] In one embodiment of the present invention, Figure 5 As shown, the limiting insert arm 100 includes an integrally connected guide insertion section 101 and a plug-in limiting section 102, so the cross-sectional size of the guide insertion section 101 gradually decreases from one end connected to the plug-in limiting section 102 to the end away from the plug-in limiting section 102, and the guide insertion section 101 abuts against the stop portion 201.

[0070] In this embodiment, the limiting insert arm 100 includes an integrally connected guide insertion section 101 and a plug limiting section 102. The cross-sectional dimension of the guide insert section 101 gradually decreases from one end connected to the plug limiting section 102 to the end away from the plug limiting section 102. Specifically, the surface of the guide insert section 101 on the side facing away from the shell structure forms an inclined plane, and the inclined plane is inclined toward the shell structure from one end connected to the plug limiting section 102 to the end away from the plug limiting section 102. In this way, when the limiting insert arm 100 passes through the notch structure of the adapter 20, because the cross-sectional dimension of the end of the guide insert section 101 along the axial direction is smaller than the cross-sectional dimension of the limiting slot 20a along the axial direction, the limiting insert arm 100 can be Quickly enter the limiting slot 20a, and after rotating a certain angle, the outer peripheral wall of the plug-in limiting section 102 abuts against the inner groove wall of the limiting slot 20a to realize the clamping and fixation of the first clamping part and the second clamping part, and in the assembled state, the guide insertion section 101 abuts against the stop part 201; further, the end of the guide insertion section 101 away from the plug-in limiting section 102 can be rounded to form an arc guide end 103. In this way, in the process of the first clamping part sliding relative to the second clamping part, the jamming problem can be effectively reduced, ensuring the smooth rotation of the adapter ring 10, and the arc-shaped guide end can make the limiting arm 100 easier and smoother to insert and rotate out of the limiting slot 20a, thereby improving the convenience of operation.

[0071] In one embodiment of the present invention, Figure 3 As shown, at least one of the inner circumferential wall of the adapter ring 10 and the outer circumferential wall of the adapter mating piece 20 is provided with at least one elastic positioning piece 30, and the other of the inner circumferential wall of the adapter ring 10 and the outer circumferential wall of the adapter mating piece 20 is provided with a positioning hole 30a adapted to the elastic positioning piece 30. In the assembled state, each elastic positioning piece 30 is inserted into a positioning hole 30a.

[0072] The elastic positioning member 30 is spaced apart from the first clamping portion or the second clamping portion.

[0073] In the present embodiment, in order to further improve the fastening effect of the adapter ring 10 and the adapter fitting 20 in the assembled state of the adapter structure, at least one elastic locating member 30 is provided on one of the inner circumferential wall of the adapter ring 10 and the outer circumferential wall of the adapter fitting 20, and a positioning hole 30a adapted to the elastic locating member 30 is provided on the other. Specifically, for example, one or more elastic locating members 30 are provided on the inner circumferential wall of the adapter ring 10. The elastic locating member 30 can be a rubber plunger made of elastic material, which can be compressed and deformed by the outer circumferential wall of the adapter fitting 20. After rotating the adapter ring 10 by a certain angle, the elastic locating member 30 is aligned with the positioning hole 30a. At this time, the elastic locating member 30 loses the constraint of the outer circumferential wall of the adapter fitting 20, and is deformed and restored under the action of elastic potential energy, so that part of the structure of the elastic locating member 30 is inserted into the positioning hole 30a to lock the assembled state of the adapter ring 10 and the adapter fitting 20, thereby improving the connection stability of the adapter structure. Of course, the elastic locating member 30 can also be provided on The outer peripheral wall of the adapter fitting 20 and the positioning hole 30a are provided on the inner peripheral wall of the adapter ring 10, which is not limited here. Similarly, in order to realize that part of the structure of the elastic positioning member 30 is inserted into the positioning hole 30a, the elastic positioning member 30 can also be a component form of a spring connected to the positioning glass bead. For example, one end of the spring is fixed to the inner peripheral wall of the adapter ring 10, and the positioning glass bead abuts the other end of the spring. When the adapter ring 10 rotates relative to the adapter fitting 20, the exposed end of the positioning glass bead can be constrained by the adapter fitting 20. So that part of its structure is retracted into the inner wall of the adapter ring 10 (it can be understood that the inner wall of the adapter ring 10 can be provided with a limit hole to accommodate the spring and the locking glass bead). When the locking glass bead is aligned with the positioning hole 30a, the locking glass bead is reset and enters the positioning hole 30a to achieve the positioning effect. Furthermore, the elastic positioning member 30 is spaced apart from the first clamping part or the second clamping part. In this way, the adapter structure forms multiple connection areas in the circumferential direction, which effectively improves the connection reliability of the first clamping part and the second clamping part.

[0074] In one embodiment of the present invention, Figure 5 As shown, the inner peripheral wall 10a of the adapter ring 10 is provided with an elastic positioning member 30, and the outer peripheral wall 20A of the adapter fitting 20 is provided with a positioning hole 30a;

[0075] The outer peripheral wall 20A of the adapter fitting 20 forms a guide arc groove 20b between a positioning hole 30a and a second clamping portion;

[0076] It is defined that the adapter ring 10 can be rotated along a first rotation direction so that the adapter structure enters an assembled state;

[0077] The depth of the guide arc groove 20b gradually decreases along the first rotation direction.

[0078] In this embodiment, the elastic positioning member 30 is provided on the inner peripheral wall 10a of the adapter ring 10, the positioning hole 30a and the second clamping portion are provided on the outer peripheral wall 20A of the adapter fitting 20, and the outer peripheral wall 20A of the adapter fitting 20 is further provided with a guide arc groove 20b, at least one end of the guide arc groove 20b extends along the outer peripheral wall 20A of the adapter fitting 20 to a positioning hole 30a or a second clamping portion. Of course, both ends of each guide arc groove 20b can extend along the outer peripheral wall 20A of the adapter fitting 20 to an adjacent positioning hole 30a and an adjacent second clamping portion. In this way, the outer circumference of the adapter fitting 20 can be reduced, thereby reducing the diameter of the adapter fitting 20 and thus reducing the installation area of ​​the adapter fitting 20; further, The depth of the guide arc groove 20b gradually decreases along the first rotation direction. It should be explained that the groove depth refers to the length of the guide arc groove 20b along the radial direction of the adapter fitting 20. The first rotation direction refers to the direction in which the first clamping portion of the adapter ring 10 can be screwed into the second clamping portion of the adapter fitting 20 when the user assembles the adapter ring 10 and the adapter fitting 20. For example, in this embodiment, the first rotation direction is clockwise, that is, the user can assemble the adapter ring 10 and the adapter fitting 20 by rotating the adapter ring 10 clockwise to put the adapter structure into an assembled state. Specifically, when preparing to assemble the adapter structure, the elastic positioning member 30 of the adapter ring 10 aligns the guide arc groove 20b with one end close to the adjacent second clamping portion (such as Figure 9 , and then rotates along the first rotation direction (which can be clockwise). During the continuous rotation, as the groove depth of the guide arc groove 20b gradually decreases, the elastic end of the elastic positioning member 30 is squeezed by the groove bottom wall of the guide arc groove 20b, resulting in gradual compression. Subsequently, when the elastic end of the elastic positioning member 30 moves to the guide arc groove 20b close to an adjacent positioning hole 30a, the inner bottom wall of the guide arc groove 20b coincides with the outer peripheral wall 20A of the adapter 20 (as shown in FIG. Figure 9 b end in the middle), so that the elastic positioning member 30 is at the maximum compression, and then rotates a certain angle along the first rotation direction, the elastic end of the elastic positioning member 30 is aligned with the positioning hole 30a, and after the elastic end of the elastic positioning member 30 loses its constraint, it is inserted into the positioning hole 30a under the action of its own elastic potential energy, thereby completing the assembly of the adapter ring 10 and the adapter mating member 20, so that the adapter structure enters the assembled state; in this process, because the elastic positioning member 30 is gradually compressed, the user's assembly feel can be ensured, and at the same time, the cooperation between multiple elastic positioning members 30 and the guide arc groove 20b can effectively prevent slipping problems during the assembly process.
