[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0022] like Figures 1 to 2 As shown in the figure, this application provides a power-assisted charging connector, including a socket 100, a plug 200 and a power-assisted rod 300.

[0023] The plug 200 is inserted into the socket 100. The outer wall of the plug 200 is provided with a first positioning groove 210, a second positioning groove 220, and a third positioning groove 230. The first positioning groove 210 and the third positioning groove 230 are located on both sides of the second positioning groove 220, which is an arc-shaped groove. The assist rod 300 is used to drive the plug 200 into or out of the socket 100. The assist rod 300 is provided with a positioning protrusion 310, which can be inserted into the first positioning groove 210, the second positioning groove 220, and the third positioning groove 230 respectively. The assist rod 300 has a first working state, a second working state, and a third working state. In the first working state, the positioning protrusion 310 is inserted into the first positioning groove 210. In the second working state, the positioning protrusion 310 is slidably engaged with the second positioning groove 220. In the third working state, the positioning protrusion 310 is inserted into the third positioning groove 230.

[0024] Understandably, in the first working state, when the plug 200 is not inserted into the socket 100, the positioning protrusion 310 is inserted into the first positioning groove 210, locking the assisting rod 300 and the plug 200 together. This facilitates alignment of the plug 200 and the socket 100 without requiring additional support for the assisting rod 300. In the second working state, when the plug 200 is inserted into the socket 100 but not fully, the positioning protrusion 310 slides along the second positioning groove 220, allowing the assisting rod 300 to rotate relative to the plug 200. In the third working state, when the plug 200 is inserted into the socket 100 and fully inserted, the positioning protrusion 310 is inserted into the third positioning groove 230, locking the assisting rod 300 and the plug 200 together.

[0025] In addition, the assist rod 300 has a symmetrical structure, with two symmetrical positioning protrusions 310 on it.

[0026] The power-assisted charging connector of this application embodiment has a first positioning groove 210, a second positioning groove 220 and a third positioning groove 230 on the outer side wall of the plug 200 respectively cooperating with the positioning protrusion 310, so that the power-assisted rod 300 has a holding force in both the first working state and the third working state, ensuring that the power-assisted rod 300 remains stable relative to the plug 200.

[0027] like Figures 1 to 2As shown, in some embodiments, the first positioning groove 210 and the second positioning groove 220 are circular grooves. Since the positioning protrusion 310 is a cylinder, the shape of the positioning protrusion 310 is adapted to the first positioning groove 210 and the second positioning groove 220, thereby improving the connection reliability between the positioning protrusion 310 and the first positioning groove 210 and the second positioning groove 220, and thus ensuring the locking stability of the assist rod 300 relative to the plug 200.

[0028] like Figures 1 to 2 As shown, in some embodiments, the assist rod 300 is rotatably connected to the plug 200.

[0029] Understandably, the assist lever 300 switches between the first working state, the second working state, and the third working state by rotating relative to the plug 200.

[0030] like Figures 1 to 2 As shown, in some embodiments, the outer wall of the plug 200 is provided with a pivot 240, and the assist rod 300 is provided with a rotating hole 320 that mates with the pivot 240. The pivot 240 mates with the rotating hole 320, so that the assist rod 300 is connected to the plug 200, and the assist rod 300 can rotate around the pivot 240 on the outer wall of the plug 200, thereby causing the assist rod 300 to drive the plug 200 into or out of the socket 100.

[0031] like Figures 1 to 2 As shown, in some embodiments, the peripheral wall of the rotating shaft 240 is provided with a limiting block 241, the limiting block 241 is spaced apart from the side wall of the plug 200, and the assist rod 300 is provided with a limiting hole 330 that cooperates with the limiting block 241, and the limiting hole 330 is connected to the rotating hole 320.

[0032] Understandably, the limiting hole 330 is positioned close to the plug 200. When the assist rod 300 is installed into the plug 200, it is first rotated to a certain position so that the limiting block 241 can pass through the limiting hole 330 and be placed in the rotating hole 320. When the assist rod 300 rotates relative to the plug 200, the rotating shaft 240 and the limiting block 241 on the rotating shaft 240 rotate relative to the rotating hole 320. At the same time, the limiting block 241 can also prevent the rotating shaft 240 from disengaging from the rotating hole 320 along its axial direction, thereby preventing the assist rod 300 from disengaging from the plug 200.

[0033] like Figures 1 to 2 As shown, in some embodiments, the outer wall of the plug 200 is provided with a stop block 250, and the assist rod 300 is provided with an abutment groove 340 that cooperates with the stop block 250.

[0034] Understandably, the abutment groove 340 is a semi-open groove. This design facilitates the disengagement of the stop block 250 from the abutment groove 340 when the assist rod 300 is in the second working state. When the assist rod 300 is in the first working state, the stop block 250 contacts one end of the abutment groove 340, thereby preventing the assist rod 300 from over-rotating. When the assist rod 300 is in the third working state, the stop block 250 contacts the other end of the abutment groove 340, thereby reducing the wobble of the assist rod 300 and improving the connection stability between the assist rod 300 and the plug 200.

[0035] like Figures 1 to 2 As shown, in some embodiments, the socket 100 is provided with a mating member, and the assist rod 300 is provided with a sliding groove that slides with the mating member. Part of the sliding groove is arc-shaped. By engaging the mating member on the socket 100 with the sliding groove of the assist rod 300, the assist rod 300 can easily drive the plug 200 to be inserted into or removed from the socket 100.

[0036] In the initial stage of the connection between the plug 200 and the socket 100, the assist rod 300 is in the first working state, the plug 200 is facing the socket 100, the opening of the slide is facing the mating part, and the mating part has not entered the slide.

[0037] When the plug 200 mates with the socket 100, the plug 200 is moved so that the mating part enters the opening of the groove. The assist rod 300 is rotated, and the mating part moves along the groove and away from the opening of the groove. The distance between one end of the assist rod 300 and the plug 200 gradually decreases, and the assist rod 300 drives the plug 200 to insert into the socket 100. During this process, the assist rod 300 sequentially switches from the first working state to the second working state and then to the third working state.

[0038] When the plug 200 disengages from the socket 100, the assist rod 300 is rotated in the opposite direction. The mating part moves along the slide groove and toward the opening of the slide groove. The distance between one end of the assist rod 300 and the plug 200 gradually increases, and the assist rod 300 drives the plug 200 to disengage from the socket 100. During this process, the assist rod 300 sequentially switches from the third working state to the second working state and then to the first working state.
