[0039] like Figure 1 and Figure 2 As shown, the charging device of the utility model comprises a charging body 1, a connecting assembly 3 and a charging line 2, and one end of the charging body 1 is provided with an opening facing away from the charging body 1 ( Figure 2 The rotating chamber 11 is provided on the right side of the figure. The connecting assembly 3 is located in the rotating chamber 11. The charging cable 2 passes through the connecting assembly 3 and is electrically connected to the charging body 1. Under the action of the connecting assembly 3, the angle between the charging body 1 and the charging cable 2 can be changed, making the charging body 1 more flexible.
[0040] like Figure 3 As shown, and based on Figure 3In the orientation shown, one end of the charging body 1 is provided with a rotating bin 11 with an opening facing the upper side of the charging body 1. In one or more embodiments, the rotating bin 11 is provided in a bowl-shaped configuration with a closed mouth. The inner wall of the rotating bin 11 is provided smoothly, and the cavity formed by the rotating bin 11 is the same as the cavity formed by the bowl-shaped structure. Alternatively, the cavity formed by the rotating bin 11 can be placed in the cavity as long as the sphere can be placed in the cavity and the sphere will not escape from the cavity. In one or more embodiments, a first recess 111 is provided on the inner side wall of the rotating bin 11 in a direction away from the opening of the rotating bin 11, and the number of the first recesses 111 is six, and the first recesses 111 are evenly spaced along the circumferential direction of the rotating bin 11.

A slideway is formed between the connector 31 and the rotating bin 11, which is away from the opening direction of the rotating bin 11. The ball 32 is located in the slideway and is configured to be able to roll in the slideway so that the charging body 1 swings relative to the connector 31. In one or more embodiments, the side of the connector 31 is an arc surface. Alternatively, the side of the connector 31 can be an ellipsoid or a spherical surface. In one or more embodiments, six second recesses 311 opposite to the six first recesses 111 are provided on the outer side wall of the connector 31. The first recesses 111 and the second recesses 311 are provided one by one, and the first recesses 111 and the second recesses 311 are arranged together to form a slideway. And a corresponding ball 32 is provided in each slideway. By providing corresponding depressions on the inner wall of the rotating bin 11 and the outer wall of the connecting head 31 to form a slideway, a clear and stable trajectory is provided for the rolling of the ball 32, ensuring that the charging body 1 can swing smoothly and stably, further improving the accuracy and convenience of the charging operation.
[0042] It should be noted that the setting of the slide is not unique, and those skilled in the art can select the specific structure of the slide based on the specific application scenario.

There are six limiting holes 331, and each limiting hole 331 is a waist-shaped hole. When all the balls 32 are located in the middle of the length direction of the slideway, the extending direction of the waist-shaped hole is set at an angle of ninety degrees to the extending direction of the slideway. The setting of the limiting portion 33 ensures that the rolling of the ball 32 in the slideway will not deviate from the predetermined track, thereby increasing the stability and reliability of the entire device.
[0045] It should be noted that the setting of the limit part 33 is not necessary, and those skilled in the art can choose whether to set the limit part 33 and the specific structure of the limit part 33 based on the specific application scenario. Alternatively, the number of the limit holes 331 is determined according to the number of the balls 32, and the number of the limit holes 331 should be the same as or more than the number of the balls 32. Alternatively, when all the balls 32 are located in the middle of the length direction of the slideway, the angle between the extension direction of the waist-shaped hole and the extension direction of the slideway can be 80 degrees, 85 degrees, 95 degrees, 100 degrees, etc. Alternatively, the limit hole 331 can be a round hole, an elliptical hole, etc.

When one end of the charging cable 2 passes through the connector 31, the limiting teeth 21 are located in the limiting groove 312, so that the portion of the charging cable 2 in the connector 31 can remain stable and is not prone to sliding or twisting, further ensuring the stability and safety of charging. The number of replaceable limiting teeth 21 can be one, and one limiting tooth 21 is inserted into one limiting groove 312. Alternatively, the setting positions of the limiting teeth 21 and the limiting groove 312 can be interchanged. Of course, the limiting teeth 21 may not be provided.
[0047] like Figure 4 and Figure 5 As shown, in one or more embodiments, a first card slot and a second card slot spaced apart from each other are provided on the circumferential wall of the charging cable 2, the connector 31 is arranged between the first card slot and the second card slot, and a clamp 22 is provided in each of the first card slot and the second card slot. The design of the first card slot, the second card slot and the clamp 22 enhances the stability of the connection and improves the service life of the charging device. Alternatively, the first card slot and the second card slot may not be provided, and a threaded clamp 22 may be provided on the charging cable 2. Alternatively, the clamp 22 may not be provided, and the connection hole 313 and the outer side of the charging cable 2 may be connected by bonding.

The charging pile realizes the swing of the charging body 1 relative to the connector 31 by designing the rotating bin 11 and the connecting assembly 3, thereby increasing the flexibility of the charging gun head. This design makes it easier to align and insert the charging port when there is a slight deviation in the parking position of the vehicle or an error in the position of the charging port, greatly improving the ability to adapt to different vehicle models. At the same time, when charging in darkness or in bad weather conditions, due to the flexibility of the charging gun head, the user can connect to the charging port of the car more quickly and accurately, greatly improving the user experience.
