[0038] As shown in Figures 1-8 The present embodiment provides a charging pile, which comprises a base 1, a charging pile body 4 and a locking assembly. The base 1 is used for being fixed to a mounting surface, wherein the mounting surface can be the ground, so as to fix the charging pile as a whole. The charging pile body 4 is rotationally connected with the base 1. The charging pile body 4 is connected with a charging gun 8 through a charging wire 7. The charging pile body 4 is provided with a charging gun fixing position 6 for fixing the charging gun 8. The charging pile body 4 is internally provided with a circuit assembly to realize the power supply function, and can deliver electric energy to a vehicle through the charging wire 7 and the charging gun 8. The charging gun fixing position 6 is arranged to facilitate the storage and accommodation of the charging gun 8. When the charging pile body 4 rotates on the base 1, the angle of the charging gun 8 and the charging wire 7 can be adjusted in detail, so as to facilitate the charging of the user.

[0039] The locking assembly comprises the engaging portion 10, the connecting portion and the locking portion arranged in sequence from top to bottom, the charging gun 8 can provide pressure to the engaging portion 10 when the charging gun 8 is located in the charging gun fixing position 6; one end of the connecting portion is connected with the engaging portion 10 and the other end is connected with the locking portion, and the connecting portion is arranged in the charging pile body 4 to adjust the horizontal height of the locking portion; the base 1 is provided with the fixing portion for relative fixing with the locking portion, and the charging pile body 4 is further provided with the elastic member 20 for providing upward elastic force to the locking assembly, when the charging gun 8 is located in the charging gun fixing position 6, the horizontal height of the locking portion is lower than that of the fixing portion, and when the charging gun 8 is not located in the charging gun fixing position 6, the locking portion is relatively fixed with the fixing portion. When the engaging portion 10 is subjected to downward pressure, the connecting portion can drive the locking portion to displace in the vertical direction, and then the horizontal height of the locking portion is adjusted to release the relative fixing between the locking portion and the fixing portion, so that the charging pile body 4 is not limited to rotate by the locking assembly; when the engaging portion 10 is not subjected to downward pressure, the elastic member 20 makes the locking portion rise and be relatively fixed with the fixing portion, so that the locking assembly is relatively fixed with the base 1, and since the locking assembly is arranged in the through hole of the charging pile body 4, the locking assembly is abutted with the side wall of the through hole when the locking assembly is fixed, so that the rotation of the charging pile body 4 is limited. The charging pile described above associates the locking of the charging pile body 4 with the plugging and unplugging of the charging gun 8 through the cooperation between the locking assembly and the charging gun 8, so that the operation steps of the user are reduced, and the operation is simple and fast; meanwhile, the linkage between the charging gun 8 and the locking assembly is realized through the mechanical structure, so that the control circuit does not need to be additionally designed, the subsequent maintenance is facilitated, and the cost is low.

[0040] Specifically, when the charging gun 8 is located in the charging gun fixing position 6, the lower surface of the charging gun 8 and the lower surface of the charging wire 7 can be abutted with the upper surface of the engaging portion 10 to provide pressure to the engaging portion 10. In some other embodiments, structures facilitating the engagement with the engaging portion 10, such as engaging protrusions, can also be arranged at the corresponding positions of the charging gun 8 and the charging wire 7, which are not limited in the present embodiment. Further, the engaging portion 10 is a U-shaped clamping rod, when the charging gun 8 is located in the charging gun fixing position 6, the charging wire 7 can be clamped on the top of the U-shaped clamping rod, and the U-shaped clamping rod can be pressed downward by the weight of the charging gun 8 and the charging wire 7. It can be understood that when the charging gun fixing position 6 fixes the charging gun 8, it can also help the charging gun 8 and the charging wire 7 to maintain the pressed state of the U-shaped clamping rod.

[0041] Specifically, the connecting part includes a vertical connecting rod connected with the U-shaped connecting rod, the through hole includes a first through hole 9 arranged at the bottom of the charging pile fixing position, and the vertical connecting rod is arranged in the first through hole 9 to realize adjustable setting in the vertical direction. When the charging gun 8 is located in the charging gun fixing position 6, the locking part is not fixed with the fixing part, that is, the locking assembly is not fixed with the base 1, and the charging pile body 4 can rotate together with the locking assembly; when the charging gun 8 is not located in the charging gun fixing position 6, the locking part is fixed with the fixing part, that is, the locking assembly is not fixed with the base 1, and the vertical connecting rod of the charging pile body 4 abuts against the side wall of the first through hole 9 to limit the rotation of the charging pile body 4 after the charging pile body 4 is subjected to an external force, so that the charging pile body 4 is locked.

[0042] Specifically, in the embodiment, the base 1 is provided with the accommodating cavity 2, one of the inner wall of the accommodating cavity 2 and the bottom of the charging pile body 4 is provided with a sliding protrusion, and the other is provided with the annular rotating groove 3. The sliding protrusion extends into the annular rotating groove 3 and is in sliding connection with the annular rotating groove 3. Further, the sliding protrusion is arranged on the inner wall of the accommodating cavity 2, and the sliding protrusion is arranged on the bottom of the charging pile body 4. The cooperation of the sliding protrusion and the annular rotating groove 3 enables the charging pile body 4 to be rotationally connected with the base 1 while limiting the freedom degree of the charging pile body 4 in the vertical direction. Meanwhile, the annular rotating groove 3 extends downward to form an annular shell, the bottom of the annular shell is provided with an avoiding hole 15, and the connecting part can pass through the avoiding hole 15 to be connected with the locking part. The sliding protrusion can be a continuous annular edge or a plurality of sliding protrusions arranged at intervals, which is not limited in the embodiment. In some other embodiments, the base 1 can not be provided with the accommodating cavity 2 but be provided with a rotating disc at the top, the charging pile body 4 is arranged on the rotating disc, the locking assembly extends outwardly to the charging pile body 4 and cooperates with the fixing part on the base 1, which is not limited in the embodiment.

[0043] Specifically, in the embodiment, the locking part includes a gear disc 16, and the fixing part is a gear ring 17 used for clamping the gear disc 16. The circumferential direction of the gear disc 16 is provided with uniform gears, which facilitates clamping with the gear ring 17 to limit the rotation of the gear disc 16. When the gear disc 16 rotates to a certain angle, the gear disc 16 can be relatively simply clamped with the gear ring 17. It can be understood that the smaller the gear pitch and the more the number of teeth of the gear disc 16 and the gear ring 17, the more the locking angles between the gear disc 16 and the gear ring 17, and the more accurate the locking engagement of the charging pile body 4 after rotation. The number of teeth of the gear disc 16 is not limited in the embodiment.

[0044] Further, in the embodiment, the gear disc 16 is provided with a spring at the bottom, and the end of the spring away from the gear disc 16 is provided with a sliding block 19, and the bottom surface of the sliding block 19 abuts against the base 1. That is, the spring is arranged between the gear disc 16 and the base 1, and the spring is used as the elastic member 20, when the gear disc 16 is pressed down, the spring is in a compressed state, and the spring can provide upward elastic force for the gear disc 16, when the charging gun 8 is pulled out, the spring will drive the gear disc 16 to move upward and be clamped and matched with the gear ring 17. At the same time, the end of the spring away from the gear disc 16 is provided with a structure, so that the spring as a whole rotates with the rotation of the gear disc 16, and the friction between the end of the spring and the base 1 is avoided to be too large to cause the spring to be bent and affect the effect of the elastic force when the gear disc 16 rotates. In some other embodiments, the spring can also be arranged between the U-shaped connecting rod and the first through hole 9, to provide upward elastic force for the U-shaped connecting rod, drive the gear disc 16 to move upward through the connecting part, and can also be arranged between the upper surface of the gear disc 16 and the base 1, and the spring is always in a stretched state to provide upward tension for the gear disc 16. It can be understood that the elastic member 20 only needs to provide upward elastic force for the locking assembly as a whole, and the specific type and specific arrangement mode of the elastic member 20 are not limited in the embodiment.

[0045] Further, in the embodiment, the sliding block 19 is a circular sliding plate, and the base 1 is provided with an annular sliding groove 18, and the circular sliding plate is slidingly connected in the annular sliding groove 18. The circular sliding plate and the annular sliding groove 18 are arranged to facilitate the spring to keep a fixed movement path when the gear disc 16 rotates, and the spring will not be bent toward or away from the center of the circle of the movement path. At the same time, the sliding block 19 is arranged as a circular sliding plate, which can better cooperate with the annular sliding groove 18, and can avoid the hindrance caused by the edges and corners when sliding relative to each other.

[0046] Specifically, in this embodiment, the connecting part includes a limiting frame, the limiting frame includes an upper limiting frame, a lower limiting frame, and a pull edge frame 13 for connecting the upper limiting frame and the lower limiting frame, the charging pile body 4 further includes a bottom plate, and the pull edge frame 13 is arranged in the bottom plate. When the charging gun 8 and the charging wire 7 apply downward pressure to the U-shaped clamping rod, the sliding connection between the pull edge frame 13 and the bottom plate allows the limiting frame as a whole to move downward, and after moving a certain distance, the upper limiting frame will abut against the upper surface of the bottom plate, so that the connecting part as a whole cannot move downward any more. At this time, the gear disc 16 is compressed and avoids the whole gear disc 16 from colliding in the annular sliding groove 18 and damaging the corresponding structure. After the charging gun 8 is pulled out, the U-shaped clamping rod is not subjected to downward pressure, the spring pushes the gear disc 16 to move upward, the upper surface of the lower limiting frame abuts against the lower surface of the bottom plate, so that the connecting part as a whole cannot move upward any more, and the gear disc 16 and other structures can also be prevented from being damaged due to collision. Further, the through hole includes a second through hole 11, the pull edge frame 13 is arranged in the second through hole 11, and when the locking assembly is fixed relative to the base 1, the pull edge frame 13 can abut against the sidewall of the second through hole 11 to lock the charging pile body 4. Further, the limiting frame is rectangular, the upper limiting frame and the lower limiting frame are parallel to the bottom plate, so that the upper and lower limiting frames have sufficient contact area with the bottom plate and are prevented from being damaged due to uneven stress.

[0047] Further, the locking assembly is provided with a rectangular frame 12 between the vertical connecting rod and the limiting frame, which can strengthen the structural strength near the limiting frame on the basis of providing the upper limiting frame for the limiting frame, and prevent the structure of the single rod of the vertical connecting rod from being unstable. In addition, the pull plate 14 is arranged between the pull edge frame 13 and the gear disc 16, and the lower surface of the rectangular frame 12, the pull edge frame 13, and the pull plate 14 together enclose the limiting frame. The pull plate 14 is a horizontal plate, the charging gun fixing position 6 is arranged on one side of the charging pile body 4, so the through hole and the locking assembly are also located on one side of the charging pile body 4. One end of the horizontal plate is fixedly connected with the pull edge frame 13, and the other end extends to the rotation center of the charging pile body 4 and is fixedly connected with the gear disc 16 at the rotation center through a fixing member. When the charging pile body 4 rotates, the sidewall of the through hole provides a force along the rotation direction to the vertical connecting rod and the pull edge frame 13, which is then conducted to the gear disc 16 through the pull plate 14 to drive the gear disc 16 to rotate. The rotation center of the charging pile body 4 is a circle of the gear disc 16, and the force applied from the center of the gear disc 16 to the gear disc 16 can ensure that the gear disc 16 is subjected to uniform torsion and the rotation effect of the gear disc 16 is ensured.

[0048] Specifically, in the embodiment, the bottom of the charging pile body 4 is provided with a containing groove 5, and a take-up wheel 25 is arranged in the containing groove 5. The take-up wheel 25 can rotate to wind the charging wire 7 into the containing groove 5. In the initial state, the charging gun 8 is located at the charging gun fixing position 6, and most of the charging wire 7 is located inside the charging pile body 4, so as to avoid the friction caused by the exposure of the charging wire 7 to the ground, which affects the rotation of the charging pile body 4 or hinders pedestrians. When the user pulls out the charging gun 8 to charge, the charging wire 7 will be pulled out of the containing groove 5, and then the charging gun 8 is inserted into the car to complete the charging. After the charging is completed, the charging gun 8 needs to be inserted back into the charging pile body 4, and at this time, most of the charging wire 7 is still in contact with the ground, which makes it difficult for the charging pile body 4 to rotate, thereby causing difficulties for the user to use it later. The user can control the rotation of the take-up wheel 25 to wind the charging wire 7 into the containing groove 5 to avoid the exposure of most of the charging wire 7. Further, the axis of the take-up wheel 25 is provided with a rotating rod 24, the rotating rod 24 penetrates out of the containing groove 5 and is rotatably connected to the charging pile body 4 through a bearing piece. The rotating rod 24 can be driven by a hand crank, a rotary drive motor 22 or the like to drive the take-up wheel 25 to rotate. This embodiment does not make any limitation.

[0049] Further, in the embodiment, the take-up wheel 25 is provided with at least two, and the at least two take-up wheels 25 jointly hold the charging wire 7. At least one take-up wheel 25 is arranged at the output end of the rotary drive mechanism. That is, the charging wire 7 is located between the gaps between the take-up wheels 25 and directly contacts the take-up wheels 25. When the take-up wheel 25 rotates, the charging wire 7 is moved by the friction force on the surface. Further, the charging pile body 4 comprises an operation panel which is convenient for the user to operate. The direction in which the operation panel is located is the front part, and the rear part of the charging pile body 4 is fixedly connected with a protection box 21. One or more drive motors 22 are installed in the inner cavity of the protection box 21. The drive motor 22 is used as a rotary drive mechanism. The output end of the drive motor 22 is connected with a rotating rod 24. The rotating rod 24 penetrates into the containing groove 5 and is provided with a take-up wheel 25 outside the rotating rod 24. The take-up wheel 25 can rotate under the drive of the drive motor 22. It can be understood that the take-up wheel 25 driven by the drive motor 22 is a driving wheel, and the take-up wheel 25 which is not provided with a drive motor 22 and only rotates through the cooperation of a bearing piece and the rotating rod 24 is a driven wheel. The driving wheel and the driven wheel can jointly hold the charging wire 7. When the driving wheel rotates, the driven wheel rotates to wind the charging wire 7. It can be understood that the drive motor 22 can have different rotating directions. Different rotating directions can respectively realize the winding and extension of the charging wire 7. When the drive motor 22 rotates forward, the charging wire 7 can be wound into the containing groove 5. When the drive motor 22 rotates reversely, the charging wire 7 can be extended out of the containing groove 5. In some other embodiments, the rotary drive mechanism can also be a hand crank or the like manual structure. This embodiment does not make any limitation.

[0050] Further, the winding wheels 25 are two in total, one of which is a driving wheel and the other is a driven wheel, and the circumferential surfaces of the two winding wheels 25 are wrapped with rubber layers to increase the friction. The charging wire 7 is clamped in the gap between the two winding wheels 25. In some other embodiments, the winding wheels 25 can be arranged in two rows, and the charging wire 7 is clamped in the gap between the two rows of winding wheels 25; the winding wheels 25 can also be staggered, for example, two winding wheels 25 are arranged above, one winding wheel 25 is arranged below and between the two winding wheels 25, and the charging wire 7 is clamped in the gap between the upper and lower winding wheels 25, that is, the arrangement of the winding wheels 25 only needs to meet the requirement of winding the charging wire 7, and the present embodiment does not make further limitations.

[0051] Further, the user can start the driving motor 22 by using the control screen on the operation panel to rotate the driving motor 22 and wind the charging wire 7 into the inside of the accommodating groove 5, so as to avoid the charging wire 7 from contacting the ground and generating friction to affect the rotation of the charging pile body 4. In some other embodiments, the charging wire 7 can also be directly wound on a single winding wheel 25, and the charging wire 7 can be wound by rotating the winding wheel 25, or the charging wire 7 can be wound by first clamping and moving the charging wire 7 by using multiple winding wheels 25 and then winding the charging wire 7 by using the winding wheel 25, and the present embodiment does not make further limitations.

[0052] Further, the bottom of the charging gun fixing position 6 is provided with a first through hole 9, the first through hole 9 is communicated with the accommodating groove 5, the bottom of the accommodating groove 5 is a bottom plate, and the bottom plate is provided with a second through hole 11. It can be understood that the first through hole 9 and the second through hole 11 are vertical through holes, which can vertically guide the locking assembly passing therethrough, and the locking assembly can be adjusted up and down by cooperating with the first through hole 9 and the second through hole 11.

[0053] Specifically, in the present embodiment, the side wall of the charging pile body 4 is provided with at least one handle frame 23. The charging pile body 4 has a rectangular structure, and it is not convenient for the user to manually rotate it. The handle frame 23 arranged on the side wall facilitates the user to hold and exert force to rotate the charging pile body 4 with hands. Further, the handle frame 23 is provided with multiple handle frames and is arranged in a vertical direction, which facilitates the user to exert force to rotate the charging pile body 4 with both hands at different heights.

[0054] Specifically, the present embodiment also provides a use method of the charging pile, which is applied to the charging pile and includes the following steps:

[0055] S1, before pulling out the charging gun 8, the charging gun 8 is located in the charging gun fixing position 6, the locking part is separated from the fixing part, the charging pile body 4 is not fixed and locked, the charging pile body 4 is rotated, and the direction of the charging pile body 4 is adjusted;

[0056] S2, the charging gun 8 is taken out from the charging gun fixed position 6, the locking part is fixed opposite to the fixed part, the charging pile body 4 is fixed and locked, the charging gun 8 is connected with the automobile to charge;

[0057] S3, after completing the charging, the charging gun 8 is pulled out from the automobile and reinserted into the charging gun fixed position 6, so that the locking part is separated from the fixed part, and the locking of the charging pile body 4 is released.
