Description

Technical Field

[0001] The utility model relates to an adaptive charging cable with double ends capable of independently adjusting lengths. Background Art

[0002] Given the reliability, manufacturing cost and usage scenario limitations of wireless charging pads, charging with charging cables is currently a common method for electronic devices.

[0003] After the charging cable is connected, there is often redundant length and multiple wires are intertwined together, which not only affects the neatness and is inconvenient to organize, but also easily causes entanglement and poses a safety hazard.

[0004] The reel-type cable storage charging cable can adjust the length of the charging cable, and the charging cables at both ends are stored or released synchronously with the storage box as the center. The disadvantage of this method is that because the length of both ends is adjusted synchronously, the length of both ends of the storage box is always kept equal. When charging in the car or the storage box is placed in a limited position, the storage box cannot be placed and is suspended, which affects the convenience and stability of use. In addition, in the storage state, it is impossible to judge the length of the charging cable in the storage part.

[0005] Using clips or clamps to control the charging cable is prone to loosening and it is difficult to find a fixing point. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an adaptive charging cable with independently adjustable length at both ends. The wiring harnesses at both ends of the shell can be independently adjusted in length, which improves the flexibility of the wiring harness adjustment and is also more convenient for fixing the position of the shell, avoiding neatness problems and safety hazards caused by cluttered charging cables.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an adaptive charging cable with double ends and independently adjustable length, comprising a charging cable, wherein the two ends of the charging cable are respectively connected to a power supply end and an end connected to an electrical device, and a double-head regulator is installed on the outside of the charging cable, and the double-head regulator comprises an outer shell, and a partition in the middle of the outer shell divides the outer shell into two winding chambers, and winding shafts are rotatably installed in both winding chambers, and a spiral guide groove is provided on the winding shaft, and a torsion spring and a ratchet mechanism are respectively installed at both ends of the winding shaft, and an unlocking button of the ratchet mechanism protrudes from the outer surface of the outer shell; two wire outlet seams are provided on the outer shell, and the power supply end and the electrical device end respectively pass through the two wire outlet seams.

[0008] Furthermore, the middle position of the charging cable passes through the partition and is fixedly connected to the partition.

[0009] Furthermore, the locking force direction of the ratchet mechanism is opposite to the torsion force direction of the torsion spring.

[0010] Furthermore, the relationship between the radius r of the winding shaft, the number of turns n of the spiral guide groove in each winding chamber, the length a of the charging wire extending from the threading point of the partition to the first spiral guide groove of the winding shaft, the length b of the charging wire extending from the last spiral guide groove of the winding shaft to the wire outlet seam, and the total length L of the charging wire is as follows:

[0011] 2πrn≥L / 2-ab.

[0012] Furthermore, a fixing device is provided at the bottom of the shell, and the fixing device adopts a suction cup or a magnet.

[0013] The beneficial effect of adopting the above technical solution is that the wire harnesses at both ends of the shell of the utility model can adjust the length independently, which improves the flexibility of the wire harness adjustment and is also easier to fix the position of the shell, avoiding neatness problems and safety hazards caused by the mess of the charging cable. The adjustment method is simple and fast to adjust the length through the coordination of the torsion spring and the ratchet mechanism, and the durability is strong. The spiral guide groove allows the charging cable to be arranged in a spiral on the winding shaft, and the length of the storage part can be judged according to the position and length of the charging cable pulled out from the shell, which is convenient for planning the length requirements of charging.

[0017] See attached Figure 1 The structure of a specific embodiment of the utility model includes a charging cable 1, and the two ends of the charging cable 1 are respectively connected to a power supply end 2 and a power device end 3. A double-head regulator is installed on the outside of the charging cable 1, and the double-head regulator includes a shell 1. A partition 11 in the middle of the shell 1 divides the shell 4 into two winding chambers 5. A winding shaft 6 is rotatably installed in the two winding chambers 5. The winding shaft 6 is provided with a spiral guide groove 9. A torsion spring 7 and a ratchet mechanism 8 are respectively installed at both ends of the winding shaft 6. The unlocking button 10 of the ratchet mechanism 8 protrudes from the outer surface of the shell 4; two wire outlet seams 12 are provided on the shell 4, and the power supply end 2 and the power device end 3 are respectively passed through the two wire outlet seams 12.

[0018] The middle position of the charging cable 1 passes through the partition 11 and is fixedly connected to the partition 11 .

[0019] The locking force direction of the ratchet mechanism 8 is opposite to the torsion force direction of the torsion spring 7. The charging cable 1 can be adjusted to any suitable size.

[0020] The relationship between the radius r of the winding shaft 6, the number n of spiral guide grooves 9 in each winding chamber 5, the length a of the charging cable 1 extending from the threading point of the partition 11 to the first spiral guide groove 9 of the winding shaft 6, the length b of the charging cable 1 extending from the last spiral guide groove 9 of the winding shaft 6 to the outlet seam 12, and the total length L of the charging cable 1 is 2πrn≥L / 2-ab.

[0022] The spiral guide groove 9 allows the charging cable 1 to be arranged in a spiral on the winding shaft 6. The position where the charging cable 1 passes through the wire seam 12 of the outer shell 4 corresponds to the winding range of the charging cable 1 on the winding shaft 6. The length of the storage part is determined based on the position and the length of the charging cable 1 pulled out, providing a visual basis for planning the length requirements for charging.
