Description

Technical Field

[0001] This invention relates to the field of charging cable technology, and more specifically to an easy-to-use in-vehicle 2-in-1 charging cable. Background Technology

[0002] Currently, most commonly used car charging cables on the market are 2-in-1 or 3-in-1 car charging cables with multiple integrated interfaces. They adopt a parallel transmission wiring design, which has problems such as multiple wires being prone to tangling and knotting, accelerating cable aging and damage, inconvenient plugging and unplugging, and easy confusion with other devices, resulting in low charging efficiency. In addition, some car charging cables with multiple interfaces usually have their interfaces exposed when not in use, making them susceptible to dust, water stains, and other foreign objects. This not only affects charging performance but may also damage the interfaces due to foreign objects, shortening the lifespan of the charging cable. Although existing car charging cables have been optimized and improved with push-push structures, which can meet basic quick replacement needs to a certain extent, there are still problems with storage and effective protection. At the same time, the interface replacement operation of these charging cables is complicated, requiring tools or cumbersome disassembly steps, making it difficult to meet users' needs for quick and convenient interface switching.

This embodiment describes a user-friendly in-vehicle 2-in-1 charging cable. The push button 5 has a through hole 52; a drive pin 53 is movably mounted in the through hole 52; the inner wall of the outer drive ring 6 has a first drive groove; the outer wall of the inner drive ring 7 has a second drive groove; one end of the drive pin 53 is movably mounted in the first drive groove; the other end of the drive pin 53 is movably mounted in the second drive groove; the first drive groove includes a first positive spiral groove 61 and a first negative spiral groove 62; the first positive spiral groove 61 and the first negative spiral groove 62 have opposite rotation directions; the bottom of the first positive spiral groove 61... The first positive spiral groove 61 is connected to the bottom of the first reverse spiral groove 62; the second driving groove includes a second positive spiral groove 71 and a second reverse spiral groove 72; the first positive spiral groove 61 and the second positive spiral groove 71 have the same direction of rotation; the first reverse spiral groove 62 and the second reverse spiral groove 72 have the same direction of rotation; the bottom of the second positive spiral groove 71 is connected to the bottom of the second reverse spiral groove 72; a first detachment slope 63 is provided between the bottom of the first positive spiral groove 61 and the bottom of the first reverse spiral groove 62; a second detachment slope 73 is provided at the top of the second positive spiral groove 71 and the top of the second reverse spiral groove 72.This embodiment describes a user-friendly in-vehicle 2-in-1 charging cable. The inner drive ring 7 is movably equipped with a first baffle 81 and a second baffle 82. A pull cord 83 is provided between the first baffle 81 and the second baffle 82. The first baffle 81 has a first stop block 84; the second baffle 82 has a second stop block 85. The first stop block 84 is telescopically movably located at the bottom of the second positive spiral groove 71; the second stop block 85 is telescopically movably located at the bottom of the second negative spiral groove 72. Both the first baffle 81 and the second baffle 82 are equipped with a first permanent magnet 86; the other end of the drive pin 53 is equipped with a second permanent magnet 54. This embodiment describes a user-friendly in-vehicle 2-in-1 charging cable. The housing 12 contains a locking plate 9; the push button 5 has an elastic locking claw 55; the locking plate 9 has a locking groove; the free end of the elastic locking claw 55 is movably disposed within the locking groove; the locking groove includes a first vertical locking groove 91, a first oblique locking groove 92, a second vertical locking groove 93, a second oblique locking groove 94, a third oblique locking groove 95, a third vertical locking groove 96, and a fourth oblique locking groove 97 connected in sequence; the fourth oblique locking groove 97 has a guide slope 98; a blocking step 99 is provided between the first vertical locking groove 91 and the fourth oblique locking groove 97; and a slot 90 is provided between the second oblique locking groove 94 and the third oblique locking groove 95.

[0023] Specifically, in this embodiment, the easy-to-use vehicle-mounted two-in-one charging cable has its first interface 2 and second interface 3 stored in the housing 12 when not in use. 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. When the user presses down the button 5 for the first time, as the button 5 moves downward, one end of the drive pin 53 moves along the first positive spiral groove 61, causing the drive ring to rotate clockwise. This causes the rotating wheel 41 to rotate clockwise, resulting in the first half tooth 42 meshing with the first rack. The first push rod 44 pushes the first interface 2 to gradually extend. When the button 5 descends to the bottom, the elastic locking pawl 55 moves sequentially 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 into the slot 90, thereby locking the position of the button 5. In addition, one end of the drive pin 53 moves to the bottom of the first positive spiral groove 61 and disengages from the first drive groove through the first disengagement inclined surface 63, allowing the other end of the drive pin 53 to enter the second drive groove.

[0024] The user presses down the button 5 a second time, causing the elastic locking pawl 55 to disengage from the slot 90 and reset sequentially 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 stop block 84 extends out of the second positive spiral slot 71 at this time, the other end of the drive pin 53 moves upward along the second negative spiral slot 72, causing the drive ring to rotate clockwise. This drives the rotating wheel 41 to continue rotating clockwise, causing the first half tooth 42 to separate from the first rack, thus opening the first interface. 2. The first push rod 44 is reset. When the drive pin 53 moves to the top of the second anti-spiral groove 72, it disengages from the second drive groove through the second disengagement ramp 73, so that one end of the drive pin 53 enters the first anti-spiral groove 62 of the first drive groove. When the other end of the drive pin 53 moves along the second anti-spiral groove 72, the second stop 85 is pulled out into the second anti-spiral groove 72 through the cooperation of the first permanent magnet 86 and the second permanent magnet 54, and the first stop 84 is retracted from the second positive spiral groove 71.

[0025] The user begins to press the button 5 for the third time. As the button 5 moves downward, one end of the drive pin 53 moves along the first anti-spiral groove 62, causing the drive ring to rotate counterclockwise. This causes the rotating wheel 41 to rotate counterclockwise, resulting in the second half tooth 43 meshing with the second rack. The second push rod 45 pushes the second interface 3 to gradually extend. When the button 5 descends to the bottom, the elastic locking pawl 55 moves sequentially 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 into the slot 90, thereby locking the position of the button 5. In addition, one end of the drive pin 53 moves to the bottom of the first anti-spiral groove 62 and disengages from the first drive groove through the first disengagement inclined surface 63, allowing the other end of the drive pin 53 to enter the second drive groove.

[0026] The user presses the button 5 for the fourth time, causing the elastic locking pawl 55 to disengage from the slot 90 and reset sequentially 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 second stop block 85 extends out of the second reverse spiral slot 72 at this time, the other end of the drive pin 53 moves upward along the second positive spiral slot 71, causing the drive ring to rotate counterclockwise. This drives the rotating wheel 41 to continue rotating counterclockwise, causing the second half tooth 43 to separate from the second rack, thus opening the second interface. 3 and the second push rod 45 are reset. When the drive pin 53 moves to the top of the second positive spiral groove 71, it disengages from the second drive groove through the second disengagement ramp 73, so that one end of the drive pin 53 enters the first positive spiral groove 61 of the first drive groove. When the other end of the drive pin 53 moves along the second positive spiral groove 71, the first stop block 84 is pulled out into the second positive spiral groove 71 through the cooperation of the first permanent magnet 86 and the second permanent magnet 54, and the second stop block 85 is retracted from the second negative spiral groove 72.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
