Description

Technical Field

[0001] The present invention relates to the technical field of charging cables, and in particular to an easy-to-use vehicle-mounted two-in-one charging cable. Background Art

[0002] At present, most of the commonly used car charging cables on the market are two-in-one or three-in-one car charging cables with integrated multiple interfaces. They adopt a parallel transmission wiring design, which has problems such as multiple wires easily getting tangled and knotted, accelerating wire aging and breakage, inconvenient plugging and unplugging, and easy confusion of devices, resulting in low charging efficiency. In addition, some car charging cables with multiple interfaces are usually exposed when not in use, which are easily contaminated by foreign matter such as dust and water stains. This not only affects the charging performance, but may also cause damage to the interface due to foreign matter, shortening the service life of the charging cable. Although the existing car charging cables have been optimized and improved in combination with the push-push structure, they can meet the basic quick replacement needs to a certain extent, but there is still the problem of being unable to be stored and effectively protected.

[0039] Specifically, when the easy-to-use in-vehicle two-in-one charging cable described in this embodiment is not in use, the first interface 2 and the second interface 3 are both stored in the housing 12. At this time, one end of the drive pin 53 is located at the top of the first positive spiral groove 61, and the elastic locking claw 55 is located at the top of the first vertical locking groove 91;

[0040] The user starts to press the press key 5 for the first time. During the downward movement of the press key 5, one end of the driving pin 53 moves along the first positive spiral groove 61, causing the driving ring to rotate clockwise, driving the rotating wheel 41 to rotate clockwise, so that the first half tooth 42 engages with the first rack, and the first push rod 44 pushes the first interface 2 to gradually extend. When the press key 5 drops to the bottom, the elastic locking claw 55 moves to the card slot 90 through the first vertical locking groove 91, the first oblique locking groove 92, the second vertical locking groove 93 and the second oblique locking groove 94 in sequence, thereby locking the position of the press key 5. In addition, one end of the driving pin 53 moves to the bottom of the first positive spiral groove 61, and disengages from the first driving groove through the first disengagement slope 63, so that the other end of the driving pin 53 enters the second driving groove.

[0041] The user starts to press the button 5 for the second time, so that the elastic locking claw 55 disengages from the card slot 90, and returns to its original position through the third oblique locking slot 95, the third vertical locking slot 96, the fourth oblique locking slot 97 and the first vertical locking slot 91. Since the first stopper 84 now extends out of the second positive spiral slot 71, the other end of the driving pin 53 moves upward along the second reverse spiral slot 72, thereby causing the driving ring to rotate clockwise, driving the rotating wheel 41 to continue to rotate clockwise, and the first half tooth 42 separates from the first rack, so that the first interface 2 and the first push rod 44 is reset. When the driving pin 53 moves to the top of the second reverse spiral groove 72, it disengages from the second driving groove through the second disengagement slope 73, so that one end of the driving pin 53 enters the first reverse spiral groove 62 of the first driving groove, and when the other end of the driving pin 53 moves along the second reverse spiral groove 72, the second stopper 85 is sucked out to the second reverse spiral groove 72 through the cooperation of the first permanent magnet 86 and the second permanent magnet 54, and the first stopper 84 is retracted from the second positive spiral groove 71.

[0042] The user starts to press the press key 5 for the third time. During the downward movement of the press key 5, one end of the driving pin 53 moves along the first reverse spiral groove 62, so that the driving ring rotates counterclockwise, driving the rotating wheel 41 to rotate counterclockwise, so that the second half tooth 43 engages with the second rack, and the second push rod 45 pushes the second interface 3 to gradually extend. When the press key 5 drops to the bottom, the elastic locking claw 55 moves to the card slot 90 through the first vertical locking groove 91, the first oblique locking groove 92, the second vertical locking groove 93 and the second oblique locking groove 94 in sequence, thereby locking the position of the press key 5. In addition, one end of the driving pin 53 moves to the bottom of the first reverse spiral groove 62, and disengages from the first driving groove through the first disengagement slope 63, so that the other end of the driving pin 53 enters the second driving groove.

[0043] The user starts to press the button 5 for the 10th time, so that the elastic locking claw 55 disengages from the card slot 90, and resets through the third oblique locking slot 95, the third vertical locking slot 96, the fourth oblique locking slot 97 and the first vertical locking slot 91 in sequence. Since the second stopper 85 now extends out of the second reverse spiral slot 72, the other end of the driving pin 53 moves upward along the second positive spiral slot 71, thereby causing the driving ring to rotate counterclockwise, driving the rotating wheel 41 to continue to rotate counterclockwise, and the second half tooth 43 separates from the second rack, so that the second interface 3 and the second push rod 45 is reset. When the driving pin 53 moves to the top of the second positive spiral groove 71, it disengages from the second driving groove through the second disengagement slope 73, so that one end of the driving pin 53 enters the first positive spiral groove 61 of the first driving groove, and when the other end of the driving pin 53 moves along the second positive spiral groove 71, the first stopper 84 is sucked out to the second positive spiral groove 71 through the cooperation of the first permanent magnet 86 and the second permanent magnet 54, and the second stopper 85 is retracted from the second reverse spiral groove 72.
