[0035] Specifically, a sliding plate 2 is slidingly installed on the surface of the mounting seat 1, reset springs 23 are arranged at both ends of the sliding plate 2, and one end of each reset spring 23 is fixed to the mounting seat 1, such as Figure 1 and Figure 2As shown, the sliding plate 2 can slide up and down along the length direction of itself, when the sliding plate 2 slides, the reset springs 23 at both ends of the sliding plate 2 are elastically deformed at the same time, and can reset the sliding of the sliding plate 2, one side of the sliding plate 2 is provided with a movable plate 21, a gap is left between the movable plate 21 and the sliding plate 2, and a supporting spring 22 is arranged between the movable plate 21 and the sliding plate 2, the arrangement of the supporting spring 22 enables the movable plate 21 and the sliding plate 2 to approach or move away from each other, and at the same time, the movable plate 21 itself can also tilt within a certain angle range, the supporting spring 22 can be used to reset the movable plate 21;

[0036] Secondly, the guide cylinder 3 is fixed to the surface of the movable plate 21, the inner cavity of the guide cylinder 3 movably penetrates and connects the hollow shaft 4, the hollow shaft 4 can only slide along the length direction of the guide cylinder 3, and when the guide cylinder 3 tilts with the movable plate 21, the hollow shaft 4 can also tilt, a protective cover 5 is sleeved outside the hollow shaft 4, one end of the hollow shaft 4 is fixed to one end of the protective cover 5, a gap is left between the protective cover 5 and the hollow shaft 4, one end of the protective cover 5 is fixedly provided with a hollow seat 51, a charging head 6 is arranged outside the hollow seat 51, and the charging head 6 is used for charging docking, the cable on the charging head 6 can pass through the inner cavities of the hollow seat 51 and the hollow shaft 4 in sequence;

[0037] Further, the hollow ball 7 is rotatably installed in the inner cavity of the hollow seat 51, a threaded cylinder is fixed on one side of the surface of the hollow ball 7, and the charging head 6 is threadedly connected with the hollow ball 7, as Figure 4 and Figure 3 As shown, the charging head 6 and the hollow ball 7 are relatively fixedly connected, since the hollow ball 7 can freely rotate within a certain angle range around the center of the ball, the inclination angle of the charging head 6 can be arbitrarily adjusted, when the charging head 6 is docked, the charging head 6 can be tilted under the action of the weight of the charging cable, so that the connection between the charging head 6 and the charging cable can be kept on the same straight line as much as possible, thereby reducing the bending force of the charging cable on the charging head 6, and avoiding the breakage and damage of the charging head 6 after long-term and repeated use.

[0038] In order to reset the charging head 6, the application also has a reset plate 8 movably arranged in the inner cavity of the hollow seat 51, the reset plate 8 can slide in any direction in the plane where it is located, the other side of the surface of the hollow ball 7 is provided with a gear slot one 72, the surface of the reset plate 8 is provided with a gear slot two 81, and the gear slot two 81 and the gear slot one 72 are engaged with each other, when the hollow ball 7 rotates, the hollow ball 7 can drive the reset plate 8 to slide through the engagement transmission between the gear slot one 72 and the gear slot two 81, a strip-shaped groove 82 is arranged at the edge of the reset plate 8, a sleeve plate 83 corresponding to the strip-shaped groove 82 is sleeved at the edge of the reset plate 8, the sleeve plate 83 is fixed with an elastic telescopic rod 84, the end of the elastic telescopic rod 84 is fixed to the inner wall of the hollow seat 51, the elastic telescopic rod 84 is provided with a spring, the reset plate 8 will compress the elastic telescopic rod 84 when it slides, the elastic telescopic rod 84 can be used to reset the reset plate 8, thereby realizing the reset of the hollow ball 7 and the charging head 6.

[0039] In order to prevent dust and water from entering the inner cavity of the hollow seat 51, the reset plate 8 and the hollow seat 51 are both arranged in a square structure, and the side length of the hollow seat 51 is greater than that of the reset plate 8, the reset plate 8 can only slide in the inner cavity of the hollow seat 51, one end of the hollow seat 51 is provided with an opening, and the opening is provided with a flexible layer 52, the middle part of the flexible layer 52 is adhesively fixed to the surface of the hollow ball 7, as shown in Figure 3 The flexible layer 52 is mainly used to seal the inner cavity of the hollow seat 51, so as to prevent dust and rain from entering the inner cavity of the hollow seat 51, and the flexible layer 52 itself has flexibility and will not interfere with the rotation and inclination of the charging head 6.

[0040] In order to facilitate the reset of the hollow ball 7, the application also has a ring-shaped cover 71 movably sleeved on the outer side of the middle part of the hollow ball 7, and the ring-shaped cover 71 is fixedly connected with the inner wall of the hollow seat 51, the inner wall of the ring-shaped cover 71 is in an arc structure and is attached to the surface of the hollow ball 7, the ring-shaped cover 71 is used for positioning the hollow ball 7, so as to ensure that the hollow ball 7 can only rotate around its center and will not be shifted in position, the gear slot one 72 and the gear slot two 81 are both provided with a plurality of gear slots, the plurality of gear slots one 72 are concentrically arranged on the surface of the hollow ball 7 and have diameters increasing in turn, the plurality of gear slots two 81 are concentrically arranged on the surface of the reset plate 8 and have diameters increasing in turn, as shown in Figure 4 It can be seen from the drawings that the plurality of gear slots one 72 and the plurality of gear slots two 81 are both circular structures and are engaged one by one, so as to ensure that the hollow ball 7 can always drive the reset plate 8 to move during rotation, and vice versa, when the reset plate 8 is reset by the elastic telescopic rod 84, it can drive the hollow ball 7 to reset automatically.

[0041] In order to avoid the relative rotation between the protective cover 5 and the guide cylinder 3, the hollow shaft 4 is slidably arranged in the middle of the movable plate 21, and the hollow shaft 4 is not hindered by the movable plate 21. The hollow shaft 4 is sleeved with a main spring 41 on the outer side. The two ends of the main spring 41 are provided with annular seats 42. The surface of the guide cylinder 3 and one annular seat 42 is provided with annular teeth one 31 and annular teeth two 421, respectively, and the two are meshed with each other. The main spring 41 is mainly used for resetting the sliding of the hollow shaft 4, so that the hollow shaft 4 and the protective cover 5 always have a tendency to move away from the guide cylinder 3. The relative rotation between the annular teeth two 421 and the annular teeth one 31 can avoid the rotation of the annular seat 42. When the user rotates the hollow seat 51 and the protective cover 5, the relative rotation between the protective cover 5 and the guide cylinder 3 will occur. At this time, the main spring 41 is twisted and elastically deformed (acts as a torsional spring). After the user releases the hollow seat 51, the protective cover 5 and the hollow seat 51 can be automatically reset under the torsional force of the main spring 41.

[0042] In order to facilitate the docking of the charging head 6, the other end of the hollow shaft 4 is fixed with a stop ring 43. The stop ring 43 is used to limit the sliding of the hollow shaft 4, so as to avoid the mutual separation between the hollow shaft 4 and the guide cylinder 3 under the elastic force of the main spring 41. A plurality of limit clamping grooves 32 and a plurality of guide sliding grooves 33 are arranged in the inner wall of the guide cylinder 3 in a ring array. The limit clamping grooves 32 and the guide sliding grooves 33 are sequentially and spacedly arranged. The surface of the hollow shaft 4 is movably inserted with a clamping block 44 corresponding to the plurality of limit clamping grooves 32, as shown in Figure 8 The number of the limit clamping grooves 32, the guide sliding grooves 33 and the clamping block 44 is consistent. The plurality of clamping blocks 44 can be located in the inner cavities of the plurality of limit clamping grooves 32 or in the inner cavities of the plurality of guide sliding grooves 33. By rotating the hollow shaft 4, the clamping block 44 can be controlled to correspond to the limit clamping groove 32 or the guide sliding groove 33. Figure 9 As shown in , when the clamping block 44 corresponds to the limit clamping groove 32, the hollow shaft 4 and the guide cylinder 3 cannot slide relative to each other. When the clamping block 44 corresponds to the guide sliding groove 33, the hollow shaft 4 and the guide cylinder 3 can slide relative to each other. The advantage of this design is that before the user needs to dock the charging head 6, the hollow seat 51 is first rotated to drive the protective cover 5 and the hollow shaft 4 to rotate until the clamping block 44 corresponds to the limit clamping groove 32. At this time, the hollow shaft 4 cannot slide relative to the guide cylinder 3, which is easy to dock the charging head 6. Then, the hollow seat 51 is released. The main spring 41 automatically resets the rotation of the hollow shaft 4 under the torsional force until the clamping block 44 corresponds to the guide sliding groove 33. At this time, the hollow shaft 4 and the guide cylinder 3 can slide relative to each other, so as to adjust the position of the hollow shaft 4.

[0043] In order to accommodate the card block 44, the application also has an inner boss 45 fixed on the inner wall of the hollow shaft 4, the surface of the hollow shaft 4 is provided with a receiving groove 46, and the card block 44 is slidingly installed in the inner cavity of the receiving groove 46. The receiving groove 46 is mainly used for accommodating the card block 44. One end of the card block 44 is provided in a rounded "<" shape structure. The other end of the card block 44 is fixed with a limiting rod 47. The outer side of the middle part of the limiting rod 47 is sleeved with a thrust spring 48 located in the inner cavity of the receiving groove 46. One end of the limiting rod 47 is movably penetrated through the inner wall of the inner boss 45 and is fixedly connected with a nut. As shown in Figure 10 It can be seen that the elastic force of the thrust spring 48 always has a tendency to push the card block 44 away from the inner cavity of the inner boss 45, but the limiting rod 47 and the nut at one end of the limiting rod 47 can limit the sliding of the card block 44, ensuring that the card block 44 will not completely separate from the receiving groove 46.

[0044] In order to avoid the hollow ball 7 and the reset plate 8 from separating, the application also has an annular plate 85 provided on the side of the reset plate 8 away from the hollow ball 7, and a gap is left between the annular plate 85 and the reset plate 8. The annular plate 85 and the reset plate 8 are fixedly connected through a convex ring. The outer side of the annular plate 85 is provided with a limiting ring 9. The inner part of the limiting ring 9 is provided with a hollow groove 91. The edge of the annular plate 85 is slidingly installed in the inner cavity of the hollow groove 91. The limiting ring 9 is fixedly connected with the hollow seat 51 through a bolt. As shown in Figure 5 The annular plate 85 can only slide in the inner cavity of the hollow groove 91. The distance between the reset plate 8 and the limiting ring 9 remains unchanged. By positioning the limiting ring 9, the position of the reset plate 8 can be limited, so that the reset plate 8 and the hollow ball 7 always remain in a state of adhesion, and they will not separate to cause the tooth groove one 72 and the tooth groove two 81 to fail to engage.

[0045] In order to slidingly install the sliding plate 2, the application also has a guide sliding rail 11 fixed on the surface of the mounting seat 1. The surface of the sliding plate 2 is fixed with a guide sliding block 24 corresponding to the guide sliding rail 11, and the guide sliding block 24 and the guide sliding rail 11 are slidingly connected, as shown in Figure 2 It can be seen that the guide sliding rail 11 is used to guide the sliding of the guide sliding block 24, thereby limiting and guiding the sliding of the sliding plate 2. The support spring 22 is provided with four and is located at the four corners of the sliding plate 2. By pulling the movable plate 21 to incline, the support springs 22 at different positions of the corner of the movable plate 21 will be elastically deformed to different degrees, but the movable plate 21 and the sliding plate 2 always remain corresponding and will not separate from each other.

[0046] In order to avoid the damage of the supporting spring 22 and the reset spring 23, the application further has a short pin shaft arranged in the inner cavity of the supporting spring 22, one end of the short pin shaft is fixed with the sliding plate 2, the other end of the short pin shaft is movably penetrated through the hole arranged on the movable plate 21, the diameter of the hole arranged on the movable plate 21 is larger than the diameter of the short pin shaft, the other end of the short pin shaft is provided with a circular plate with a larger diameter, which is used for preventing the movable plate 21 from being separated from the short pin shaft, since the inner diameter of the hole arranged on the movable plate 21 is larger than the diameter of the short pin shaft, the movable plate 21 itself will not interfere with the short pin shaft when it is inclined, the arrangement of the short pin shaft can be used for avoiding the bending of the supporting spring 22, thereby preventing the dislocation between the movable plate 21 and the sliding plate 2, and avoiding the excessive stretching deformation of the supporting spring 22 caused by the too large distance between the movable plate 21 and the sliding plate 2, so as to avoid the damage of the supporting spring 22, the inner cavity of the reset spring 23 is inserted with a long pin shaft, one end of the long pin shaft is fixed with the sliding plate 2, the other end of the long pin shaft is movably penetrated through and connected with the vertical plate on the mounting base 1, the arrangement of the long pin shaft can be used for avoiding the bending deformation of the reset spring 23, so as to avoid the damage of the reset spring 23.

[0047] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of the present application is defined by the appended claims and their equivalents.
