[0001] The present invention relates to the technical field of new energy vehicle charging equipment, and in particular to a charging pile and a method for using the same. Background Art

[0002] A charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electrical energy to electric vehicles. It can charge various models of electric vehicles according to different voltage levels so that the electric vehicles can store enough electricity to support their operation.

[0003] Most of the charging piles in the prior art are fixed directly on the ground using bolt assemblies. Although this method ensures the stability and safety of the charging pile, due to the different locations of the charging ports of new energy vehicles and the limited number of charging piles, sometimes the parking position of the vehicle is at a certain angle to the charging pile, which is inconvenient to use the charging gun for plugging and charging. At the same time, the charging cable of the charging pile is generally very thick, and the overall weight is very heavy when combined with the charging gun. At this time, forcibly pulling the charging gun to plug into the car is not only laborious, but also causes damage to the charging cable and the ground due to friction. In addition, there are some rotatable charging piles in the prior art to adjust the angle of the charging pile, but such charging piles are usually provided with a manually operated locking structure to fix the charging pile to prevent the charging pile from rotating during charging, which is complicated to operate and inconvenient to use; or additional corresponding control circuits and structures are designed, which are costly.

[0038] like Figure 1-Figure 8 As shown, this embodiment provides a charging pile, which includes: a base 1, a charging pile body 4 and a locking assembly. The base 1 is used to be fixed on 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 rotatably connected to the base 1, and the charging pile body 4 is connected to a charging gun 8 through a charging line 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 provided with a circuit component inside to realize the power supply function, and can transmit electric energy to the car through the charging line 7 and the charging gun 8. The setting of the charging gun fixing position 6 facilitates the storage and storage of the charging gun 8. When the charging pile body 4 rotates on the base 1, the angles of the charging gun 8 and the charging line 7 can be specifically adjusted to facilitate charging by users.

[0039] The locking assembly includes a coupling part 10, a connecting part and a locking part, which are arranged in sequence from top to bottom. When the charging gun 8 is located in the charging gun fixing position 6, the coupling part 10 can be subjected to downward pressure; one end of the connecting part is connected to the coupling part 10 and the other end is connected to the locking part, and the connecting part is passed through the charging pile body 4 to adjust the horizontal height of the locking part; the base 1 is provided with a fixing part for relative fixation with the locking part, and the charging pile body 4 is also provided with an elastic part 20 that can provide an 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 part is lower than the horizontal height of the fixing part. When the charging gun 8 is not in the charging gun fixing position 6, the locking part and the fixing part are relatively fixed. When the joint part 10 is subjected to downward pressure, the locking part can be driven to move in the vertical direction through the connecting part, thereby adjusting the horizontal height of the locking part so that the locking part and the fixing part are released from relative fixation. At this time, the charging pile body 4 will not be restricted from rotating by the locking component; when the joint part 10 is not subjected to downward pressure, the elastic member 20 causes the locking part to rise and be relatively fixed with the fixing part. At this time, the locking component and the base 1 are relatively fixed. Since the locking component is inserted into the through hole of the charging pile body 4, the locking component abuts against the side wall of the through hole when it is fixed to limit the rotation of the charging pile body 4. The above-mentioned charging pile associates the locking and fixing of the charging pile body 4 with the inevitable action of plugging and unplugging the charging gun 8 through the cooperation of the locking component and the charging gun 8, thereby reducing the operating steps of the user and making the operation simple and quick; at the same time, the linkage between the charging gun 8 and the locking component is realized through the mechanical structure, and no additional control circuit design is required, which is also convenient for subsequent inspection and maintenance and has a low cost.

[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 cable 7 can abut against the upper surface of the joint 10 to provide pressure to the joint 10. In some other embodiments, a structure that is convenient for engaging with the joint 10, such as an engaging protrusion, can also be provided at the corresponding positions of the charging gun 8 and the charging cable 7, which is not limited in this embodiment. Further, the joint 10 is a U-shaped lever, and when the charging gun 8 is located in the charging gun fixing position 6, the charging cable 7 can be placed on the top of the U-shaped lever, and the U-shaped lever is pressed down by the weight of the charging gun 8 and the charging cable 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 cable 7 to maintain the downward pressure on the U-shaped lever.

[0041] Specifically, the connection part includes a vertical connecting rod connected to the U-shaped lever, and the through hole includes a first through hole 9 provided at the bottom of the charging pile fixing position, and the vertical connecting rod is penetrated through the first through hole 9 to realize the adjustable setting in the vertical direction. When the charging gun 8 is located in the charging gun fixing position 6, the locking part and the fixing part are released from relative fixation, that is, the locking assembly is not relatively fixed to 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 and the fixing part are relatively fixed, that is, the locking assembly is not relatively fixed to the base 1, and the charging pile body 4 is subjected to external force. The vertical connecting rod will abut against the side wall of the first through hole 9 to limit the rotation of the charging pile body 4, thereby locking the charging pile body 4.

[0042] Specifically, in this embodiment, the base 1 is provided with a housing chamber 2, and one of the inner wall of the housing chamber 2 and the bottom of the charging pile body 4 is provided with a sliding protrusion, and the other is provided with an annular groove 3, and the sliding protrusion extends into the annular groove 3 and is slidably connected with the annular groove 3. Further, the sliding protrusion is provided on the inner wall of the housing chamber 2, and the sliding protrusion is provided on the bottom of the charging pile body 4. The cooperation of the sliding protrusion and the annular groove 3 makes the charging pile body 4 and the base 1 rotatably connected and limits the degree of freedom of the charging pile body 4 in the vertical direction. At the same time, the annular groove 3 extends downward with an annular shell, and the bottom of the annular shell is provided with an avoidance hole 15, and the connecting part can pass through the avoidance hole 15 and connect with the locking part. Among them, the sliding protrusion can be a continuous annular edge or a sliding protrusion arranged at intervals, which is not limited in this embodiment. In some other embodiments, the base 1 can also be provided with a rotating disk at the top instead of the housing chamber 2, and the charging pile body 4 is provided on the rotating disk, and the locking assembly extends outward from the charging pile body 4 and cooperates with the fixed part on the base 1, which is not limited in this embodiment.

[0043] Specifically, in this embodiment, the locking portion includes a gear plate 16, and the fixing portion is a toothed ring 17 for engaging with the gear plate 16. The gear plate 16 has uniform gears on its circumference, which is convenient for engaging with the toothed ring 17 to limit the rotation of the gear plate 16. When the gear plate 16 rotates to a certain angle, the gear plate 16 rises and can be engaged with the toothed ring 17 more easily. It can be understood that the smaller the pitch of the gear plate 16 and the toothed ring 17 and the denser the number of teeth, the more locking angles there are between the gear plate 16 and the toothed ring 17, and the more accurate the locking engagement of the charging pile body 4 after rotation. This embodiment does not limit the number of teeth of the gear plate 16.

[0044] Further, in this embodiment, a spring is provided at the bottom of the gear disc 16, and a slider 19 is provided at one end of the spring away from the gear disc 16, and the bottom surface of the slider 19 abuts against the base 1. That is, a spring is provided 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, which can provide an 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 engage with the toothed ring 17. At the same time, the spring is provided at one end away from the gear disc 16 so that the spring as a whole rotates with the rotation of the gear disc 16, so as to avoid excessive friction between one end of the spring and the base 1 when the gear disc 16 rotates, causing the spring to bend and affecting the effect of the elastic force. In some other embodiments, the spring can also be provided between the U-shaped lever and the first through hole 9 to provide an upward elastic force for the U-shaped lever, and drive the gear disc 16 to move upward through the connecting portion. It can also be provided between the upper surface of the gear disc 16 and the base 1, and the spring is always in a stretched state to provide an upward pulling force for the gear disc 16. It can be understood that the elastic member 20 only needs to provide an upward elastic force for the locking assembly as a whole, and the specific type and specific configuration of the elastic member 20 are not limited in this embodiment.

[0045] Furthermore, in this embodiment, the slider 19 is a circular slider, and an annular slot 18 is provided in the base 1, and the circular slider is slidably connected to the annular slot 18. The provision of the circular slider and the annular slot 18 is conducive to ensuring that the spring maintains a fixed motion path when rotating with the gear plate 16, and the spring will not bend toward or away from the center of the circle generated by the motion path. At the same time, the slider 19 is set as a circular slider to better cooperate with the annular slot 18, and can avoid obstacles caused by edges and corners when sliding relative to each other.

[0046] Specifically, in this embodiment, the connection part includes a limit frame, and the limit frame includes an upper limit frame, a lower limit frame, and a lifting frame 13 for connecting the upper limit frame and the lower limit frame. The charging pile body 4 also includes a bottom plate, and the lifting frame 13 is inserted into the bottom plate. When the charging gun 8 and the charging line 7 apply downward pressure to the U-shaped lever, the lifting frame 13 and the bottom plate are slidably connected and cooperated to make the limit frame move downward as a whole. After moving a certain distance, the upper limit frame will abut against the upper surface of the bottom plate, and the connection part as a whole cannot move downward any further. At this time, the gear plate 16 compresses the spring and prevents the gear plate 16 from hitting the annular groove 18 as a whole, damaging the corresponding structure; after the charging gun 8 is pulled out, the U-shaped lever is not subjected to downward pressure, and the elastic force of the spring pushes the gear plate 16 to move upward, and the upper surface of the lower limit frame abuts against the lower surface of the bottom plate, and the connection part as a whole cannot move upward any further, which can also prevent the gear plate 16 and other structures from being damaged by the impact. Furthermore, the through hole includes a second through hole 11, and the lifting frame 13 is inserted into the second through hole 11. When the locking assembly is relatively fixed to the base 1, the lifting frame 13 can abut against the side wall of the second through hole 11 to lock the charging pile body 4. Furthermore, the limit frame is rectangular, and the upper limit frame and the lower limit frame are parallel to the bottom plate, so that the upper and lower limit frames have sufficient contact area with the bottom plate to avoid damage to the upper and lower limit frames due to uneven force.

[0047] Furthermore, the locking assembly is provided with a rectangular frame 12 between the vertical connecting rod and the limit frame, and the rectangular frame 12 can strengthen the structural strength near the limit frame on the basis of providing an upper limit frame for the limit frame, so as to avoid the instability of the single rod structure of the vertical connecting rod. In addition, a lifting plate 14 is provided between the lifting frame 13 and the gear plate 16, and the lower surface of the rectangular frame 12, the lifting frame 13 and the lifting plate 14 together enclose the limit frame. The lifting plate 14 is a horizontal plate, and the charging gun fixing position 6 is provided 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 to the lifting frame 13, and the other end extends to the rotation center of the charging pile body 4, and is relatively fixed to the gear plate 16 at the rotation center through a fixing member. When the charging pile body 4 rotates, the side wall of the through hole provides force along the rotation direction to the vertical connecting rod and the lifting frame 13, and then transmits the force to the gear plate 16 through the lifting plate 14 to drive the gear plate 16 to rotate. The rotation center of the charging pile body 4 is the circle of the gear plate 16. Applying the force from the center of the circle of the gear plate 16 to the gear plate 16 can ensure that the gear plate 16 is subjected to uniform torque, thereby ensuring the rotation effect of the gear plate 16.

[0048] Specifically, in this embodiment, a receiving groove 5 is provided at the bottom of the charging pile body 4, and a take-up wheel 25 is provided in the receiving groove 5. The rotation of the take-up wheel 25 can store the charging line 7 in the receiving groove 5. In the initial state, the charging gun 8 is located at the charging gun fixing position 6, and most of the charging line 7 is located inside the charging pile body 4, so as to avoid the friction caused by the contact with the ground caused by the exposure of the charging line 7, which affects the rotation of the charging pile body 4 or hinders pedestrians. When the user pulls out the charging gun 8 for charging, a pulling force will be provided to the charging line 7 to pull the charging line 7 out of the receiving groove 5, and then the charging gun 8 will be inserted into the car to complete the charging. After charging is completed, the charging gun 8 needs to be reinserted into the charging pile body 4. At this time, most of the charging line 7 is still in contact with the ground, which makes it difficult for the charging pile body 4 to rotate, which brings difficulties to the user's subsequent use. The user can control the take-up wheel 25 to rotate and store the charging line 7 in the receiving groove 5 to avoid exposing most of the charging line 7. Furthermore, a rotating rod 24 is provided at the axis of the take-up wheel 25. The rotating rod 24 extends out of the accommodating groove 5 and is rotatably connected to the charging pile body 4 through a bearing. The rotating rod 24 can be driven by a hand crank, a rotating drive motor 22, etc. to drive the take-up wheel 25 to rotate, which is not limited to the present embodiment.

[0049] Furthermore, in this embodiment, at least two take-up wheels 25 are provided, at least two take-up wheels 25 clamp the charging line 7 together, and at least one take-up wheel 25 is provided at the output end of the rotary drive mechanism. That is, the charging line 7 is located between the gaps between the take-up wheels 25 and is in direct contact with the take-up wheels 25. When the take-up wheels 25 rotate, the charging line 7 is driven to move by the friction force on the surface. Furthermore, the charging pile body 4 includes an operation panel that is convenient for users to operate. With the direction where the operation panel is located as the front, the rear of the charging pile body 4 is fixedly connected with a protective box 21, and one or more drive motors 22 are installed in the inner cavity of the protective box 21. The drive motor 22 is used as a rotary drive mechanism, and the output end of the drive motor 22 is connected with a rotating rod 24, which penetrates into the receiving groove 5 and is provided with a take-up wheel 25 on the outer surface of the rotating rod 24. The take-up wheel 25 can be rotated under the drive of the drive motor 22. It is understandable that the take-up wheel 25 driven by the drive motor 22 is the driving wheel, and the take-up wheel 25 that is not provided with the drive motor 22 and is only rotated by the bearing member in cooperation with the rotating rod 24 is the driven wheel. The driving wheel can cooperate with the driven wheel to clamp the charging line 7 together, and when the driving wheel rotates, the driven wheel cooperates to rotate to store the charging line 7. It is understandable that the drive motor 22 can have different rotation directions, and different rotation directions can respectively realize the storage and extension of the charging line 7. When the drive motor 22 rotates forward, the charging line 7 can be stored in the receiving slot 5, and when the drive motor 22 rotates reversely, the charging line 7 can be extended out of the receiving slot 5. In some other embodiments, the rotation drive mechanism can also be a manual structure such as a hand crank, which is not limited in this embodiment.

[0050] Furthermore, there are two take-up wheels 25, one of which is a driving wheel and the other is a driven wheel. The circumferential surfaces of the two take-up wheels 25 are wrapped with a rubber layer to increase friction. The charging cable 7 is clamped in the gap between the two take-up wheels 25. In some other embodiments, the take-up wheels 25 can be arranged in two rows, and the charging cable 7 is located in the gap between the two rows of take-up wheels 25; the take-up wheels 25 can also be staggered, such as two take-up wheels 25 are arranged above, and a take-up wheel 25 is arranged below and located between the two take-up wheels 25, and the charging cable 7 is clamped by the gap between the upper and lower take-up wheels 25, that is, the arrangement of the take-up wheel 25 only needs to be able to drive the charging cable 7 to be stored, and this embodiment does not make any restrictions on this.

[0051] Furthermore, the user can use the control panel on the operation panel to start the drive motor 22, so that the drive motor 22 rotates to retract the charging cable 7 into the receiving groove 5, thereby preventing the charging cable 7 from contacting the ground and generating friction to affect the rotation of the charging pile body 4. In some other embodiments, the charging cable 7 can also be directly wound around a single take-up wheel 25, and the charging cable 7 can be reeled up by rotating the take-up wheel 25. Alternatively, multiple take-up wheels 25 can be used to clamp and move the charging cable 7 and then the take-up wheel 25 can be used to reel up the charging cable 7, which is not limited in this embodiment.

[0052] Furthermore, a first through hole 9 is provided at the bottom of the charging gun fixing position 6, and the first through hole 9 is connected to the receiving groove 5. The bottom of the receiving groove 5 is the 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 both vertical through holes, which can play a role of vertical guidance for the locking component penetrated therein, and the locking component can be adjusted by sliding up and down through the cooperation with the first through hole 9 and the second through hole 11.

[0053] Specifically, in this embodiment, at least one handle frame 23 is provided on the side wall of the charging pile body 4. The charging pile body 4 is a rectangular parallelepiped structure, which is not convenient for users to rotate manually. The handle frame 23 provided on the side wall is convenient for users to hold and rotate the charging pile body 4. Furthermore, multiple handle frames 23 are provided and spaced apart in the vertical direction, so that users can rotate the charging pile body 4 with their hands at different heights.

[0054] Specifically, this embodiment further provides a method for using a charging pile, which is applied to the above-mentioned charging pile and includes the following steps:

[0055] S1. Before pulling out the charging gun 8, the charging gun 8 is located at the charging gun fixing position 6, the locking portion is separated from the fixing portion, the charging pile body 4 is not fixed and locked, and the charging pile body 4 is rotated to adjust the direction of the charging pile body 4;

[0056] S2, the charging gun 8 is taken out from the charging gun fixing position 6, the locking part is relatively fixed to the fixing part, the charging pile body 4 is fixed and locked, and the charging gun 8 is connected to the car for charging;

[0057] S3. After charging is completed, the charging gun 8 is pulled out from the car and reinserted into the charging gun fixing position 6 to separate the locking portion from the fixing portion, thereby releasing the lock of the charging pile body 4.

[0058] Furthermore, the specific method of S1 is: when in use, since the charging gun 8 is inserted into the inside of the charging gun fixing position 6, and the charging line 7 is placed on the top of the U-shaped lever, the U-shaped lever pushes the gear plate 16 down through the connecting part. At this time, the descending gear plate 16 will compress a plurality of springs and separate from the gear ring 17. At this time, the charging pile body 4 can rotate through the cooperation of the sliding protrusion and the annular groove 3. During rotation, the spring can move together with the circular slide plate at the bottom of the spring in the annular groove 18. At this time, the user pushes or pulls the handle frame 23 to realize the rotation of the charging pile body 4, thereby adjusting the overall direction of the charging pile, so as to facilitate the subsequent pulling out of the charging gun 8 for charging;

[0059] Furthermore, the specific method of S2 is: after the adjustment of the direction of the charging pile body 4 is completed, the charging gun 8 is pulled out of the charging gun fixing position 6 by hand. At this time, the U-shaped lever loses the pressure brought by the weight of the charging line 7 and the charging gun 8, so that several springs can push the gear plate 16 upward, and the lifted gear plate 16 is located in the same plane and meshed with the toothed ring 17. If an external force is provided to rotate the charging pile body 4 at this time, the vertical connecting rod and the lifting frame 13 in the locking assembly will abut against the side wall of the through hole, and the charging pile body 4 will be locked and fixed. Then, the drive motor 22 is started by using the control panel at the front of the charging pile body 4. After the drive motor 22 is started, it will drive the take-up wheel 25 to rotate in the opposite direction through the rotating rod 24, and pull out the charging line 7 inside the accommodating groove 5 to extend its overall length, providing a sufficient moving distance for the charging gun 8. After the extension of the charging line 7 is completed, the drive motor 22 stops. At this time, the user connects the charging gun 8 to the car for charging;

[0060] Furthermore, the specific method of S3 is: after charging is completed, the charging gun 8 is removed and reinserted into the charging gun fixing position 6. At the same time, the charging line 7 is placed on the top of the U-shaped lever to press it down and drive the gear plate 16 to be pressed down and separated from the gear ring 17. At this time, since most of the charging line 7 is located outside the charging pile body 4, it is not convenient for the charging pile body 4 to adjust the direction later. The user can then use the control panel to start the drive motor 22 to drive the drive motor 22 to rotate forward and retract the charging line 7 into the accommodating slot 5.
