[0001] The present invention relates to the technical field of chargers, and in particular to a vehicle-mounted retractable charging cable that is easy to switch between uses. Background Art

[0002] In modern life, as people's dependence on electronic devices continues to increase, vehicles have become an indispensable mobile space for people to travel and a key scenario for the battery life of electronic devices. Whether it is a mobile phone, tablet computer, or dash cam, all devices need to be charged in time during driving to ensure normal use.

[0003] However, in-car charging currently faces many challenges. For one thing, there are significant differences in the charging ports of various charging devices, such as the common Type-C interface, Lightning interface, and Micro-USB interface. This means that car owners often need to carry multiple charging cables with different interfaces to meet the charging needs of different devices during daily driving. On the other hand, existing charging cable designs are mostly limited to a single interface type and lack consideration for easy interface replacement and storage of multiple cables. When car owners need to switch charging devices in the car, it is difficult to quickly find the appropriate interface, which seriously affects usage efficiency. More importantly, multiple charging cables placed haphazardly in the car can easily become tangled, which not only increases the difficulty of use, but also may cause damage to the cables due to frequent pulling and entanglement, thereby shortening their service life.

[0033] The present invention is further described with reference to the following examples.

[0034] Depend on Figures 1 to 9 As can be seen, the embodiment of the present invention provides a retractable vehicle-mounted charging cable that is easy to switch between uses, including a housing 1; a sleeve 2 is provided within the housing 1; a plurality of reels 3 are arranged along the height direction within the housing 1, each reel 3 is rotatably sleeved outside the sleeve 2, and each reel 3 is wound with a charging cable 11; the housing 1 has a plurality of storage openings 12 corresponding to the charging cables 11;

[0035] A driving chamber 21 is provided in the sleeve 2; a switch member 4 is movably provided in the driving chamber 21;

[0036] Each reel 3 is provided with a spiral groove 31; the sleeve 2 is movably provided with a plurality of drive pins 55, each drive pin 55 is respectively provided corresponding to each spiral groove 31, and is used to drive each reel 3 to rotate;

[0037] The switch member 4 is provided with a plurality of latches 42 ; each latch 42 is respectively provided corresponding to each driving pin 55 , and each latch 42 is respectively used to drive each driving pin 55 to abut against each spiral groove 31 .

[0038] Specifically, the vehicle-mounted retractable charging cable that is easy to switch between uses described in this embodiment is configured by providing multiple reels 3, each reel 3 being wound with a charging cable 11 with a different interface. When one of the charging cables 11 is needed, the switch member 4 is rotated so that one of the latching pins 42 of the switch member 4 abuts against the corresponding driving pin 55, thereby abutting the driving pin 55 against the corresponding spiral groove 31 of the reel 3. Then, by pressing the switch member 4 downward, the reel 3 is driven to rotate under the action of the driving pin 55 and the spiral groove 31, so that the charging cable 11 on the reel 3 extends out of the corresponding storage port 12.

[0039] This embodiment can conveniently switch the charging cables 11 of different interfaces by pressing the knob of the switch member 4, and can automatically store the unused charging cables 11 when switching, avoiding the problem of entanglement and clutter of the charging cables 11, and keeping the car tidy. This design not only saves space and reduces the need to carry multiple charging cables 11, but also improves the user's usage efficiency and experience. It is particularly suitable for car owners to quickly and conveniently charge different devices while driving.

[0040] In the embodiment of the present invention, the shape of the drive cavity 21, the shape of the sleeve 2, and the shape of the switch 4 are all cylindrical. By setting the shape of the drive cavity 21, the shape of the sleeve 2, and the shape of the switch 4 to be cylindrical, the overall stability can be effectively improved.

[0041] The multiple bayonet pins 42 are respectively at different heights and are located on the same vertical line; the multiple drive pins 55 are respectively at different heights and are located on different vertical lines.

[0042] Through the above arrangement, it is convenient to rotate the switch member 4 at different angles so that one of the latches 42 abuts against the corresponding drive pin 55; that is, it is convenient to rotate the switch member 4 at different angles so that different charging cables 11 extend out of the corresponding receiving port 12.

[0043] In this embodiment, a retractable, in-vehicle charging cable for easy switching is described. The outer wall of the switch member 4 is provided with multiple accommodating grooves 41. Each latch 42 is telescopically movable within each accommodating groove 41. A first spring 44 is disposed between the latch 42 and the accommodating groove 41. In this embodiment, a retractable, in-vehicle charging cable for easy switching is described. The sleeve 2 is provided with multiple lifting blocks 5 for upward and downward movement. Each lifting block 5 extends through a first channel 51 and a second channel 52. Each drive pin 55 is telescopically movable within the second channel 52 of each lifting block 5. A slider 53 is slidably disposed within the first channel 51. A second spring 54 is disposed between the slider 53 and the first channel 51. A third spring 56 is disposed between the slider 53 and the drive pin 55. Each slider 53 is configured to abut against each latch 42. In this embodiment, a fourth spring 57 is disposed between the bottom of the lifting block 5 and the sleeve 2. A coil spring 32 is disposed between each reel 3 and the sleeve 2. The embodiment of the present invention relates to a retractable vehicle-mounted charging cable that is easy to switch between uses. The inner wall of the driving cavity 21 is provided with a plurality of annular grooves 6 along the height direction. Each latch 42 is slidably disposed in each annular groove 6. Each annular groove 6 is provided with a guide groove 61 along the height direction. Each lifting block 5 is slidably disposed in the guide groove 61 of each annular groove 6. The embodiment of the present invention relates to a retractable vehicle-mounted charging cable that is easy to switch between uses. Each reel 3 is provided with a movable groove 33 along the height direction. The top of the movable groove 33 is connected to the top of the spiral groove 31. The bottom of the movable groove 33 is connected to the bottom of the spiral groove 31. The depth of the top of the movable groove 33 is greater than the depth of the top of the spiral groove 31. The depth of the bottom of the movable groove 33 is less than the depth of the bottom of the spiral groove 31. The depth of the top of the movable groove 33 is greater than the depth of the bottom of the movable groove 33. The movable groove 33 is provided with an inclined surface.

[0044] Specifically, the vehicle-mounted retractable charging cable that is easy to switch between uses described in this embodiment, when the charging cable 11 is stored in the reel 3, under the action of the fourth spring 57, the lifting block 5 is located at the top of the guide groove 61, and under the action of the second spring 54 and the third spring 56, the driving pin 55 is retracted in the second channel 52. At this time, pressing the switch member 4 will not cause the reel 3 to rotate.

[0045] When one of the charging wires 11 is needed, by rotating the switch member 4, each bayonet 42 is respectively in each annular groove 6. When the switch member 4 is rotated to a certain angle, one of the bayonet pins 42 of the switch member 4 is arranged opposite to the slider 53 in the corresponding lifting block 5. Under the action of the first spring 44, the slider 53 is pushed by the bayonet pin 42 to overcome the second spring 54 and move toward the second channel 52. Driven by the third spring 56, the driving pin 55 is extended from the second channel 52 and abuts against the top of the movable groove 33. Then, the switch member 4 is pressed downward, and the lifting member is driven by the bayonet pin 42 to The driving pin 55 moves downward until the driving pin 55 moves to the bottom of the movable groove 33 and falls into the bottom of the spiral groove 31, and the switch member 4 is released. Under the action of the fifth spring and the fourth spring 57, the switch member 4 and the lifting block 5 are moved upward and reset, so that the driving pin 55 moves along the spiral groove 31, thereby causing the reel 3 to rotate, and the charging wire 11 is extended from the corresponding receiving port 12 until the driving pin 55 falls from the top of the spiral groove 31 to the top of the movable groove 33 again. Under the action of the fourth spring 57, the coil spring 32 cannot be reset, ensuring that the charging wire 11 is in an extended state.

[0046] When the charging cable 11 needs to be stored again, the switch member 4 is rotated again to separate the latch 42 from the slider 53, and the drive pin 55 is retracted into the second channel 52. At this time, under the reset action of the winding spring 32, the reel 3 rotates in the opposite direction to rewind the charging cable 11.

[0047] The embodiment of the present invention describes a retractable vehicle-mounted charging cable that is easy to switch between uses. The width of the first channel 51 is greater than the width of the second channel 52. The width of the slider 53 is greater than the width of the second channel 52. The above arrangement can prevent the slider 53 from entering the second channel 52.

[0048] The detent 42 is tapered; a flat abutment surface 43 is provided at the bottom of the detent 42; and the first channel 51 is provided with a platform 58 that cooperates with the flat abutment surface 43. Specifically, the cooperating abutment between the platform 58 and the flat abutment surface 43 prevents the detent 42 from retracting into the receiving slot 41 when the switch member 4 is pressed downward, thereby enabling the detent 42 to drive the lifting member and the driving pin 55 downward. Furthermore, by setting the detent 42 to a tapered shape, when the charging cable 11 needs to be retracted, the detent 42 can be separated from the slider 53 by rotating the switch member 4.

[0049] In the embodiment of the present invention, a retractable vehicle-mounted charging cable that is easy to switch between uses is provided. The housing 1 is connected to a connector 7. Each charging cable 11 is electrically connected to the connector 7. The above arrangement can provide power to the charging cables 11.

[0050] A fifth spring 9 is provided between the switch element 4 and the driving cavity 21 , and the above arrangement facilitates the resetting of the switch element 4 .

[0051] In this embodiment, a retractable, in-vehicle charging cable that facilitates switching between different charging options is provided. The top of the sleeve 2 is provided with multiple indicator blocks 81; each indicator block 81 corresponds to a respective lifting block 5 and is aligned vertically with each lifting block 5. An indicator pin 82 is provided on the top of the switch member 4; the indicator pin 82 is aligned vertically with the latch 42. Specifically, this arrangement facilitates prompting the user to rotate the switch member 4 to the corresponding position, thereby extending the corresponding charging cable 11.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
