[0031] Please refer to Figures 1-5 It shows the specific structure of the preferred first embodiment of the utility model, and it is a positioning structure of folding earphone charging base, including base 10 and charging plate 20 rotatingly arranged on the base, the top surface of base 10 is concavely provided with receiving groove 30, the side of receiving groove 30 is provided with elastic twist member 40, one end of charging plate 20 is rotatably arranged at the corresponding end of receiving groove 30.

[0032] ​The elastic member 41 of the elastic twist member 40 is connected to the rotating end 21 of the charging plate 20. When the charging plate 20 is rotated to an angle of more than 30°, the elastic member 41 abuts against the positioning plate 42 sleeved on the rotating end 21, so that the charging plate 20 is vertically stored in the storage groove 30. When the charging state is switched to the storage state, the charging plate 20 is rotated to an angle of less than 30°, and the elastic member 41 drives the charging plate 20 to be stored in the storage groove 30. Compared with the positioning structure of the existing folding earphone charging base, the rotating end is provided with a bayonet, and the rotating end can be rotated to make the bayonet be clamped with the clamping block in the base, so that the charging plate is vertically stored in the storage groove 30. The positioning structure of the folding earphone charging base is that the storage groove 30 is formed in the base 10, the charging plate 20 is stored in the storage groove 30, and the rotating end 21 on both sides of the charging plate 20 is inserted into the base 10 through the side wall of the storage groove 30. When the charging plate 20 is rotated, the rotating end 21 drives the elastic member 41 in the elastic twist member 40 to be twisted, and abuts against the positioning plate 42 sleeved on the rotating end 21. After the charging plate 20 is turned to an angle of more than 30°, the charging plate 20 can be vertically stored in the storage groove 30, so that the user can charge the earphone according to the requirement.

[0033] The rotating end of the charging plate 20 is inserted into the cavity 11 of the base 10, and the elastic twist member 40 is arranged in the cavity 11.

[0034] The elastic member 41 is connected to the positioning plate 42, and the positioning plate 42 is arranged in the inner cavity of the base 10. Because the thickness of the charging plate 20 is less than that of the base 10, the elastic member 41 and the positioning plate 42 are arranged in the cavity 11.

[0035] As shown in Figure 4 The positioning plate 42 includes two spliced first plate body 421 and second plate body 422, the first plate body 421 and the second plate body 422 are L-shaped, the first plate body 421 is sleeved on the rotating end 21, and the second plate body 422 is provided with a connecting hole 423 for screw insertion. One side of the first plate body 421 is longer than the second plate body 422 and is sleeved on the rotating end 21, so that the second plate body 422 connected to the first plate body 421 is not affected by the rotating end 21. In addition, the connecting hole 423 formed in the second plate body 422 allows the positioning plate 42 to be installed in the inner cavity of the base 10 through a screw.

[0036] As shown in Figure 2As shown, the base 10 is provided with a support part 12 and a positioning part 13 corresponding to the connecting hole 423 of the second plate body 422 on the opposite inner wall, and the support part 12 and the positioning part 13 are staggered. The support part 12 is located below the second plate body 422. When the charging plate 20 is normally used, the base 10 is placed horizontally on the desktop. At this time, if the support part 12 is missing, the positioning plate 42 may fall down. The end of the positioning part 13 with the threaded hole is in contact with the connecting hole 423 on the second plate body 422. After the screw is twisted into the threaded hole, the second plate body 422 and the positioning part 13 are connected more tightly, further avoiding the positioning plate 42 from falling down due to lack of positioning, causing the elastic member 41 to not tightly contact the positioning plate 42 when the rotating end 21 rotates, and further affecting the verticality of the charging plate 20 in the storage slot 30.

[0037] As shown in the figure, Figure 4 As shown, the elastic member 41 includes a resistance spring 411 and a cam 412 connected to one end of the resistance spring 411, and the cam 412 is connected to the positioning plate 42. One side of the cam 412 is fixed to one end of the resistance spring 411, and the other side is in contact with the positioning plate 42. With the twisting of the rotating end 21, the cam 412 rotates and forms extrusion friction with the positioning plate 42, thereby limiting the rotating end 21 after rotation.

[0038] Specifically, the opposite surfaces of the cam 412 and the positioning plate 42 are provided with extrusion structures 80 that match each other. The extrusion groove 81 is provided on the positioning plate 42, and the extrusion column 82 is provided on the cam 412. With the rotation of the cam 412, the extrusion column 82 extrudes and rubs the extrusion groove 81, thereby limiting the rotating end 21 after rotation of more than 30°.

[0039] It should be noted that the diameter of the extrusion groove 81 gradually decreases in some areas, which is smaller than the diameter of the extrusion column 82, so that the extrusion column 82 can be tightly attached to the extrusion groove 81 after rotation,

[0040] As shown in the figure, Figure 5 As shown, the end of the rotating end 21 away from the charging plate 20 is provided with a threaded groove 211 and is threadedly connected with a nut 50, and the nut 50 is connected to the end of the resistance spring 411 away from the cam 412. The threaded groove 211 on the rotating end 21 allows the nut 50 to move on the rotating end 21 and extrude the resistance spring 411 while avoiding the nut 50 from falling off the rotating end 21. Ultimately, the operator can push the resistance spring 411 to the cam 412 according to actual needs, so that the elastic restoring force of the resistance spring 411 is reduced, thereby reducing the possibility of the rotating end 21 returning to the original position when the charging plate 20 rotates more than 30°.

[0041] The threaded groove 211 extends to the rotating end 21 of the resistance spring 411, so that the nut 50 rotates around the threaded groove 211, and the resistance spring 411 drives the cam 412 to press the positioning plate 42.

[0042] The base 10 is provided with a recessed clamping groove 60, and the USB transmitter 70 is clamped in the clamping groove 60. The arrangement of the USB transmitter 70 can facilitate the user to take and use the folding earphone charging base, or to place the USB transmitter 70 in the wireless earphone charged on the folding earphone charging base.

[0043] In one embodiment, the charging plate 20 is provided with a window 22, and the window 22 is provided with a light guide column 23. When the earphone is placed on the charging plate 20 for charging, the light guide column 23 can display light to help the user to distinguish the earphone power.

[0044] Specifically, the light guide column 23 is embedded in the window 22, and the light guide column 23 contains multiple circles. When the earphone is charging, the light guide column 23 emits light in a whole circle, which is easier for the user to distinguish the charging condition of the earphone.

[0045] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification made according to the technical essence of the present application shall still fall within the scope of the technical solution of the present application.
