[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See also Figure 1-11 The utility model provides a technical solution: a rotating and locking storage and charging integrated device, which is composed of a shell, a PCB conductive plate 1 3, a locking member 4, a toggle member 5, a spring 6, a winding reel 7, a PCB conductive plate 2 8, a spring 9 and a charging line 10, wherein the shell is made of insulating material, and the shell is formed by buckling an upper shell 1 and a lower shell 2. After the shell is formed, an opening is reserved on the side of the shell to allow the output end of the charging line 10 to be exposed from the inside of the shell.

[0041] A boss 11, a center axis 13, a center axis 2 14 and a spring limit block 15 are integrally formed inside the upper shell 1. The boss 11 extends toward the lower shell 2. A limit groove 12 is reserved at the end of the boss 11 for constraining one end of the spring 9, that is, one end of the spring 9 is inserted in the limit groove 12. The locking member 4 is sleeved on the outside of the center axis 13, and the two can rotate relative to each other. The toggle member 5 is eccentrically sleeved on the outside of the center axis 2 14, and the two can also rotate relative to each other. The locking member 4 and the toggle member 5 are stacked. The spring 6 is fixed on the outside of the spring limit block 15, and the spring 6 is wrapped around the outside of the toggle member 5. When the toggle member 5 rotates, one end of the spring 6 will be squeezed and deformed.

[0042] The PCB conductive plate 3 is fixed to the inner top of the upper shell 1 and is sleeved on the outside of the boss 11. The input terminal 31 is installed on the top of the PCB conductive plate 3. An opening is reserved at the top of the upper shell 1, through which the input terminal 31 can be exposed. Three transition terminals 32 are fixed inside the PCB conductive plate 3, and five conductive pins 33 are fixed inside each transition terminal 32. The end of each conductive pin 33 protrudes from the transition terminal 32.

[0043] In addition, in order to ensure that the circuit is conducted, the PCB conductive plate 28 is based on the winding drum 7 and is fixed on the top of the winding drum 7. Five annular track grooves 83 are opened on the top of the PCB conductive plate 28. When the PCB conductive plate 28 rotates with the winding drum 7 and rotates relative to the PCB conductive plate 13, the protruding end of the conductive pin needle 33 is always located in the corresponding track groove 83, that is, it always maintains contact to ensure conductivity. The output terminal 84 is installed at the bottom end of the PCB conductive plate 28, and the output terminal 84 is fixedly connected to the input end of the charging cable 10 by welding.

[0044] The winding drum 7 is rotatably arranged on the outside of the convex column 11, and a winding ring 71 is integrally formed at the bottom end of the winding drum 7, and a winding limit baffle 74 is arranged around the winding ring 71. The wire part of the charging cable 10 is wound around the outside of the winding ring 71 and will be constrained by the winding limit baffle 74. A notch 73 is partially reserved on the winding ring 71, and the mainspring 9 is located inside the winding ring 71, and the other end of the mainspring 9 is inserted into the inside of the notch 73.

[0045] A locking ring 75 is integrally formed at the top of the winding reel 7. The locking ring 75 has an opening area with a starting groove 76 reserved in the opening area. Several positioning grooves 77 are evenly distributed on the outside of other areas of the locking ring 75. The PCB conductive plate 8 is fixed inside the locking ring 75. An alignment groove 78 is provided on the inner side of the locking ring 75. An alignment protrusion 82 is integrally formed on the edge of the PCB conductive plate 8, and the alignment protrusion 82 is engaged in the alignment groove 78.

[0046] A stop protrusion 41 is integrally formed at the bottom end of the locking member 4, and "V"-shaped transition grooves 42 are provided at both ends of the stop protrusion 41. Arc-shaped avoidance grooves 43 are provided on both sides of the stop protrusion 41. The "V"-shaped transition groove 42 and the arc-shaped avoidance groove 43 allow the four corners of the stop protrusion 41 to form a convex structure. A locking protrusion 51 is integrally formed at the edge of the toggle member 5, and a sinking groove capable of accommodating the locking member 4 is reserved at the top of the toggle member 5, and a retention groove 1 52 and a retention groove 2 53 are respectively provided on the edges of the sinking groove.

[0047] Finally, it should be noted that: through hole 1 34, through hole 2 72 and through hole 3 81 are reserved in the middle of PCB conductive plate 1 3, winding reel 7 and PCB conductive plate 2 8 respectively. After the boss 11 passes through through hole 1 34, through hole 2 72 and through hole 3 81 in sequence, the limiting groove 12 opened at its end engages with one end of the mainspring 9.

[0048] Please read Figure 12-13 As shown, at the beginning, the positioning protrusion 51 is located in the starting groove 76, and the protrusion-shaped structure of the "V"-shaped transition groove 42 is located inside the retention groove 52 (as shown in the attached Fig.12 As shown in the figure in the upper left corner, when the user pulls out the charging cable 10, the charging cable 10 pulls the winding drum 7 to rotate clockwise, the mainspring 9 is forced to shrink, and at the same time, the locking ring 75 on one side of the starting groove 76 will move toward the locking protrusion 51. As the charging cable 10 is pulled out, the locking protrusion 51 will abut against the locking ring 75 (as shown in the figure below). Fig.12 The locking ring 75 pushes against the positioning protrusion 51, causing the toggle member 5 to rotate counterclockwise around the central axis 14. At this time, one end of the spring 6 is also compressed and deformed. When the edge of the locking ring 75 is tangent to the positioning protrusion 51 (as shown in the figure in the upper right corner), the locking ring 75 pushes against the positioning protrusion 51, causing the toggle member 5 to rotate counterclockwise around the central axis 14. Fig.12 As shown in the figure in the lower right corner, at this time, along with the counterclockwise rotation of the toggle member 5, the convex structure of the "V"-shaped transition groove 42 is located inside the second retention groove 53, until the locking ring 75 rotates to a certain positioning groove 77 and engages with the positioning protrusion 51, the convex structure is still inside the second retention groove 53. At this time, if the length of the charging cable 10 meets the use requirements, the user releases the charging cable 10, and the charging cable 10 will not be automatically recovered. When the charging cable 10 is to be recovered, the user needs to pull the charging cable 10 outward for a short distance to separate the positioning protrusion 51 from the positioning groove 77, and the convex structure from the second retention groove 53 is also separated, and then release the charging cable 10. Under the action of the mainspring 9, the winding drum 7 will immediately rotate counterclockwise to wind the charging cable 10;

[0049] The locking member 4 is locked and avoided by the toggle member 5 and the locking groove 77 .

[0050] After the charging cable 10 is rolled up and pulled, the charging will not be affected, because when the winding drum 7 rotates, the PCB conductive plate 2 8 also rotates synchronously. The conduction between the PCB conductive plate 2 8 and the PCB conductive plate 1 3 is achieved by the sliding track groove 83 and a plurality of conductive pin needles 33 during contact, so the charging work will not be affected.
