[0043] In the embodiment of the present invention, a vehicle-mounted retractable charging cable that is easy to switch between uses is provided with a plurality of accommodating grooves 41 on the outer wall of the switch member 4; each bayonet 42 is telescopically arranged in each accommodating groove 41; a first spring 44 is arranged between the bayonet 42 and the accommodating groove 41. In the embodiment of the present invention, a vehicle-mounted retractable charging cable that is easy to switch between uses is provided with a plurality of lifting blocks 5 that are movable in lifting and lowering of the sleeve 2; the lifting blocks 5 are provided with a first channel 51 and a second channel 52 through them; each driving pin 55 is telescopically arranged in the second channel 52 of each lifting block 5; a slider 53 is slidably arranged in the first channel 51; a second spring 54 is arranged between the slider 53 and the first channel 51; a third spring 56 is arranged between the slider 53 and the driving pin 55; each slider 53 is used to abut against each bayonet 42. In the embodiment of the present invention, a vehicle-mounted retractable charging cable that is easy to switch between uses is provided with a fourth spring 57 between the bottom of the lifting block 5 and the sleeve 2; a coil spring 32 is arranged between each reel 3 and the sleeve 2. The embodiment of the present invention is a vehicle-mounted retractable 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 bayonet 42 is slidably disposed in each annular groove 6.

[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, the switch member 4 is rotated, and 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 in the direction of the second channel 52. Driven by the third spring 56, the driving pin 55 extends out of 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 then 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 extends out of the corresponding storage 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, thereby 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 pin 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 provides 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.

[0048] The shape of the bayonet 42 is conical; the bottom of the bayonet 42 is provided with a support plane 43; the first channel 51 is provided with a support platform 58 that cooperates with the support plane 43. Specifically, through the cooperation and abutment between the support plane 43 and the support platform 58, when the switch member 4 is pressed downward, the bayonet 42 will not retract into the accommodating groove 41, so that the bayonet 42 can drive the lifting member and the driving pin 55 to move downward; in addition, by setting the shape of the bayonet 42 to be conical, when the charging cable 11 needs to be re-stored, the bayonet 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, wherein 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 switch element 4 is easily reset by the above arrangement.

[0051] In the embodiment of the present invention, a vehicle-mounted retractable charging cable that is easy to switch between uses is provided with a plurality of indicator blocks 81 at the top of the sleeve 2; each indicator block 81 is respectively provided corresponding to each lifting block 5, and each indicator block 81 and each lifting block 5 are respectively on the same vertical line; an indicator pin 82 is provided at the top of the switch member 4; the indicator pin 82 and the bayonet 42 are on the same vertical line. Specifically, through the above arrangement, it is convenient to remind the user to rotate the switch member 4 to the corresponding position, so as to extend the corresponding charging cable 11.
