Description

Technical Field

[0001] This utility model relates to the field of charging cable storage technology, specifically to an asynchronous bidirectional charging cable storage device. Background Technology

[0002] With the widespread use of portable electronic devices, charging cable storage devices have become necessities for users. Most existing charging cable storage devices adopt a synchronous bidirectional winding structure, in which two winding components share a single winding shaft and coil spring. The two winding components are not separated and are not independent of each other. The charging cable and power cord are stretched or retracted synchronously, which easily leads to cable tangling and jamming. Furthermore, the length of the cables on both sides cannot be adjusted independently, limiting the flexibility of use. In addition, existing charging cable storage devices are bulky and not easy to carry. Therefore, there is an urgent need for an asynchronous bidirectional charging cable storage device to solve the above problems. Utility Model Content

[0003] In view of this, an asynchronous bidirectional charging cable storage device with dual independent winding assemblies, which is compact in structure and occupies little space, is provided.

[0004] An asynchronous bidirectional charging cable storage device includes a housing and a winding assembly housed within the housing, and a rotary electrical connection assembly. The winding assembly includes a first winding assembly and a second winding assembly. The housing has a partition that divides the interior of the housing into a first storage compartment and a second storage compartment.

The charging cable and the power cable are electrically connected through the rotary electrical connection assembly. The first winding shaft and the second winding shaft are separate from each other and rotate independently, so that the pulling and extending actions of the charging cable and the power cable are asynchronous.

[0005] Furthermore, the first winding assembly also includes a first winding disc, which has a first disc surface and a second disc surface. The first disc surface faces away from the separator, and the second disc surface faces the separator. The first winding shaft is disposed at the center of the first disc surface.

Each annular conductive spring extends an elastic contact or point toward the corresponding conductive ring. Each annular conductive spring is electrically connected to the corresponding conductive ring through the elastic contact or point. When the charging cable or power cable is pulled out or retracted, the first or second winding shaft drives the first or second winding disc to rotate.

During the rotation, each annular conductive spring and the corresponding conductive ring always maintain an electrical connection.

[0008] Furthermore, the first winding shaft is a hollow shaft, and the first winding assembly further includes a first coil spring, a first coil spring retainer, and a first coil spring shaft.

The charging cable extends from the first cable outlet, and the power cable extends from the second cable outlet. The first cable outlet and the second cable outlet can be located on the same side or opposite sides, so that the extension direction of the charging cable and the extension direction of the power cable can be in the same direction or opposite direction.

[0010] Furthermore, the inner side of the middle portion of the separator has an inwardly extending rib ring, the edge regions of the first and second storage compartments are separated by the annular bottom wall of the rib ring, the central regions of the first and second storage compartments are connected by the inner ring of the annular bottom wall, and the rotary electrical connection assembly is connected to the rib ring.

[0011] Furthermore, the first winding assembly includes a first winding disc, the second winding assembly includes a second winding disc, and the rotary electrical connection assembly includes a main circuit board, a first multi-channel annular conductive spring and a second multi-channel annular conductive spring fixed and electrically connected to both sides of the main circuit board, and a first circuit board and a second circuit board respectively fixed to the first winding disc and the second winding disc.

The main circuit board is mounted in the positioning grooves through the positioning holes and the positioning posts.

The first winding disc and the second winding disc have through holes, and the wires of the charging cable and the power cable are electrically connected to the first circuit board and the second circuit board respectively through their corresponding through holes.

[0012] Furthermore, the shell includes an upper cover, a lower cover, and a middle frame. The middle frame and the partition are integrally formed or combined into one structure. The upper cover and the lower cover are located on both sides of the partition. The upper cover, the partition, and the middle frame together form the first storage compartment, and the lower cover, the partition, and the middle frame together form the second storage compartment.

[0013] Furthermore, the first winding shaft and the second winding shaft are arranged on the same axis.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] First, the design of using a first and second winding assembly separated by a divider in a dual storage compartment allows the charging cable and power cable to be stretched asynchronously and independently, avoiding cable pulling interference caused by synchronous winding.
