[0003] At present, the charging piles used for charging electric vehicles on the market are basically high-power gun lines with rated currents of 250A and 300A. The gun lines are heavy and difficult to drag. Users with less strength find it very difficult to drag the gun lines and may even be unable to lift the charging gun because the gun lines are too heavy.

[0004] In order to reduce the effort spent on dragging the gun line during charging and improve the convenience of dragging the gun line, the relevant technology also proposes a technical solution that can support the gun line when the gun line is dragged. However, some of these technical solutions use a crane to lift the gun line, and some use a spring and a pulley to support the gun line. The former leads to a waste of gun line length, and the latter not only leads to a waste of gun line length but also leads to a complex device structure, high cost, and waste of space.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of this application clearer, the following will further describe the implementation of this application in detail with reference to the accompanying drawings. It should be noted that the various data used in the embodiments of this application have been fully authorized by the relevant entities before use.

[0022] Please refer to Figure 1 , which shows a schematic diagram of a single rocker arm wire supporting device provided in an embodiment of the present application under an exemplary implementation.

[0023] The embodiment of the present application provides a single-arm wire support device, including a charging pile 1 standing upright on the ground, a charging gun line 12 extending from the charging pile, and one end of the charging gun line 12 is fixed on the charging gun head 8. The embodiment of the present application does not limit the charging pile 1, which can be a DC charging pile or an AC charging pile. The embodiment of the present application does not limit the position where the charging gun line extends from the charging pile. It can be extended from the top area, middle area or bottom area of ​​the charging pile, and when being dragged, it can be extended more and more until the maximum extension length is reached. The embodiment of the present application does not limit the extension length and does not constitute an implementation obstacle. The present application does not limit the size of the top area, middle area or bottom area, which only indicates the relative position relationship between each other. For example, the charging pile can be divided into three equal parts in the height direction to obtain the top area, middle area and bottom area. The charging gun head 8 is charged by inserting the charged object, such as the charging port of a charging car.

[0024] The bottom area of ​​the charging pile has a rotating device 9 and a driving motor 11 connected to the rotating device 9. The rotating device 9 is connected to the single rocker arm 5 and is used to drive the single rocker arm 5 to rotate under the drive of the driving motor 11. The single rocker arm 5 is provided with a damping telescopic arm inside, and the damping telescopic arm is used to slide in the internal cavity of the single rocker arm. The top of the damping telescopic arm is fixed to the preset position of the charging gun line 12 by the gun line fixing device 13. The embodiment of the present application does not limit the preset position. It can be a reasonable connection position between the gun line fixing device 13 and the charging gun line 12 when the damping telescopic arm of the single rocker arm completely slides out of the internal cavity. This position can be measured by experiment or set according to experience, and does not constitute an implementation obstacle. The driving motor 11 can be triggered manually or automatically. In the case of manual triggering, the user can independently control the rotation of the rotating device. The rotating device 9 and the single rocker arm 5 are arranged at the bottom area of ​​the charging pile to maximize the saving of the gun line length, so that it can basically be used to extend toward the charging port of the charging car, which saves more gun line than the boom structure and the suspension structure.

[0025] The single rocker arm 5 of the embodiment of the present application may have two degrees of freedom, one is the rotational degree of freedom, and the other is the telescopic degree of freedom. It can be driven by a driving motor to rotate, and it also has the telescopic degree of freedom. Through telescoping, it can further support the charging gun line to move further in the dragging direction. In an exemplary embodiment, the single rocker arm 5 can be referred to as a hidden rail damping telescopic arm. The hidden rail reduces the occupied space of the single rocker arm and increases its extension capacity. The reasonable configuration of damping makes the process of dragging and recovering the charging gun line smooth, thereby improving the user experience.

[0026] The charging pile 1 is provided with a charging gun seat 7 . When the charging gun head is placed on the charging gun seat 7 , the charging gun wire 12 naturally droops under the support of the charging gun head 8 and the gun wire fixing device 13 .

[0027] In one embodiment, the charging gun seat 7 is connected to a homing induction sensor 6, and the homing induction sensor 6 is used to detect whether the charging gun head 8 is placed on the charging gun seat 7; The rotating device 9 is connected to the angular displacement sensor 10, and the angular displacement sensor 10 is used to detect the rotation angle of the single rocker arm 5, that is, to detect the rotation angle of the rotating device; when the charging gun line is dragged, the rotation direction of the single rocker arm 5 is consistent with the dragging direction, that is, the movement of the charging gun line in the dragging direction is supported by rotation.

[0028] The gun line fixing device 13 is connected to the tension sensing sensor 4, and the tension sensing sensor 4 is used to detect the tension generated on the gun line fixing device 13 when the charging gun line 12 is dragged. When the gun line is dragged and moves in the dragging direction, it will drive the single rocker arm 5, thereby generating tension on the gun line fixing device 13 of the single rocker arm 5, and the tension is detected by the tension sensing sensor 4.

[0029] The homing induction sensor 6, the angular displacement sensor 10, and the tension induction sensor 4 are all connected to a charging controller 14 provided on the charging pile 1, and the charging controller 14 is used to control the rotation of the single rocker arm 5 and the power supply of the charging gun head 8. In the embodiment of the present application, it can be understood that the detection results of the angular displacement sensor 10, the tension induction sensor 4, and the homing induction sensor 6 can be obtained by the charging controller 14 in a timely manner, and no further explanation is given.

[0030] In one embodiment, the charging pile 1 is also provided with an operating screen 2 and a card reader 3. The card reader 3 and the operating screen 2 are both communicatively connected to the charging controller 14. The card reader 3 is used to detect the user's card swiping information, and the operating screen 2 is used to receive the user's instructions. The charging controller 14 is also used to control the rotation of the single rocker arm 5 and control the power supply of the charging gun head 8 when the card swiping information meets the charging requirements.

[0031] In the embodiment of the present application, the working principle of the single rocker arm wire supporting device can be summarized as follows: When the charging gun head does not leave the charging gun seat, it is in standby mode, and the hidden rail damping wire-receiving arm is in the initial position. Figure 1 It can be seen that it is placed vertically upward and does not rotate at this time. When the user swipes the card, the user removes the charging gun head from the charging gun holder, starts the drive motor, and the hidden rail damping wire take-up arm automatically starts to rotate. Figure 2 As shown, it shows a schematic diagram of the rotation of a single rocker arm in an embodiment of the present application. At this time, the damping telescopic arm of the hidden rail damping take-up arm is hidden in the internal space.

[0032] like Figure 3 As shown, it shows a schematic diagram of the telescopic single rocker arm of an embodiment of the present application. The charging gun line starts to move toward the vehicle charging socket by human power pulling. When the tension detected by the tension sensing sensor 4 is small, it can be determined that no rotation is required and it is likely that the charging port has been reached. At this time, the drive motor stops rotating and transmits back the rotation angle detected by the angular displacement sensor. If the user continues to pull the gun line, the hidden rail damping wire take-up arm quickly and automatically slides out to achieve a length that balances the gun line tension. The user can easily insert the charging gun head into the charging vehicle to start charging.

[0033] When charging is finished, the user pulls out the charging gun head from the vehicle. During the process of retracting the charging gun head, the rail-type damping take-up arm is quickly retracted and hidden, and provides buffering and damping when in place. If the rotation direction of the rotating device during the process of pulling the charging cable to charge is regarded as forward rotation, the drive motor drives the rotating device to reverse, that is, to rotate the rail-type damping take-up arm. After the charging gun head is inserted back into the charging gun seat, the rail-type damping take-up arm returns to the standby state.

[0034] Please refer to Figure 4 , which shows a flow chart of a control method for a wire support device according to an embodiment of the present application. The method is applied to the aforementioned single rocker arm wire support device, and the method comprises: S401. When the homing induction sensor 6 detects that the charging gun head 8 leaves the charging gun seat 7, the charging controller 14 triggers the drive motor 11 to start; S402. When the tension sensing sensor 4 detects that the tension generated on the gun line fixing device 13 when the charging gun line 12 is dragged is greater than the first tension value, the charging controller 14 controls the driving motor 11 to drive the rotating device 9 to rotate, and the angle between the direction of the rotation linear velocity of the rotating device 9 and the direction in which the charging gun line 12 is dragged is less than the first angle threshold; The angle between the rotational velocity of the rotating device 9 and the direction in which the charging gun line 12 is dragged is less than the first angle threshold, which means that the single rocker arm can rotate in a direction that can support the charging gun line in the dragging direction, and the first angle threshold can be less than 10 degrees. Figure 2 For example, the rotating device 9 rotates clockwise.

[0035] S403 . When the single rocker arm 5 is driven by the rotating device 9 to rotate, the angular displacement sensor 10 detects the rotation angle of the single rocker arm 5 .

[0036] by Figure 1 For example, in the standby state, the single rocker arm is pointing vertically upward. When the charging gun line is pulled toward the object to be charged, the single rocker arm rotates clockwise. The angle formed by the position after the rotation and the vertical standby position is the rotation angle. In the charging gun line recovery stage, the angle formed by the actual position of the single rocker arm 5 and the vertical standby position is the rotation angle.

[0037] S404. When the rotation angle is greater than the second angle threshold or the tension detected by the tension sensing sensor 4 is less than or equal to the first tension value, the charging controller 14 controls the drive motor 11 to stop driving the rotating device 9; S405. When the rotating device 9 stops rotating and the tension detected by the tension sensing sensor 4 is greater than or equal to the second tension value and less than the first tension value, the damping telescopic arm inside the single rocker arm 5 slides out until the charging gun line 12 is extended to the maximum length in the dragging direction or the charging gun head 8 is inserted into the charged object.

[0038] The embodiment of the present application does not limit the first tension value, the second tension value and the second angle threshold. For example, the first tension value is greater than or equal to 50 Newtons and less than or equal to 70 Newtons, the second tension value is greater than or equal to 30 Newtons and less than or equal to 45 Newtons, and the second angle threshold is greater than or equal to 80 degrees and less than or equal to 100 degrees. In one embodiment, the first tension value is 50 Newtons, the second tension value is 30 Newtons, and the second angle threshold is 90 degrees. In another embodiment, the first tension value is 70 Newtons, the second tension value is 45 Newtons, and the second angle threshold is 85 degrees.

[0039] In an exemplary embodiment, after the damping telescopic arm inside the single rocker arm 5 slides out, it may continue to trigger the rotation of the single rocker arm and the damping telescopic arm may continue to slide out after the rotation stops, including: During the process of the damping telescopic arm sliding out, if the tension sensing sensor 4 detects that the tension is greater than the first tension value and the rotation angle is less than the second angle threshold, the charging controller 14 controls the driving motor 11 to drive the rotating device 9 to continue to rotate; when the single rocker arm 5 rotates driven by the rotating device 9, the angular displacement sensor 10 detects the rotation angle of the single rocker arm 5; when the rotation angle is greater than the second angle threshold or the tension detected by the tension sensing sensor 4 is less than or equal to the first tension value, the charging controller 14 controls the driving motor 11 to stop driving the rotating device 9. When the rotating device 9 stops rotating and the tension detected by the tension sensing sensor 4 is greater than or equal to the second tension value and less than the first tension value, the damping telescopic arm inside the single rocker arm 5 continues to slide out. This is repeated until the charging gun line 12 is stretched to the maximum length in the dragging direction or the charging gun head 8 is inserted into the charged object.

[0040] After charging is completed, the method further includes: when the homing sensing sensor 6 detects that the charging gun head 8 is placed on the charging gun seat 7, the charging controller 14 controls the drive motor 11 to drive the rotating device 9 to rotate in the opposite direction; this reverse rotation is a reverse rotation relative to the rotation direction before charging. Continuing with the previous example, it can rotate counterclockwise at this time.

[0041] The angular displacement sensor 10 detects the rotation angle of the single rocker arm 5; when the rotation angle is less than the third angle threshold, the charging controller 14 controls the drive motor 11 to stop driving the rotating device (9). At this time, it can be considered that the line collection is basically completed and no reversal is required. The embodiment of the present application does not limit the third angle threshold, which can be less than or equal to 10 degrees, for example, it can be zero degrees.

[0042] In one embodiment, when the homing induction sensor 6 detects that the charging gun head 8 is placed on the charging gun seat 7 and the damping telescopic arm slides out, the damping telescopic arm is automatically recovered and hidden in the internal cavity of the single rocker arm 5. The telescopic movement of the damping telescopic arm depends on the damping sliding structure of the single rocker arm itself, and does not require electric control, which will not be elaborated without applying for embodiments.

[0043] In another embodiment, before the homing induction sensor 6 detects that the charging gun head 8 leaves the charging gun seat 7, the card swiping information detected by the card reader 3 meets the charging requirements; the embodiment of the present application does not make too many restrictions on the card swiping information meeting the charging requirements, and does not constitute an implementation obstacle. After the homing induction sensor 6 detects that the charging gun head 8 is placed on the charging gun seat 7, the operation screen 2 displays a preset message, and the preset message indicates that charging is completed.

[0044] In a specific embodiment, please refer to Figure 5 , which shows a control method architecture block diagram of an embodiment of the present application.

[0045] When the charging vehicle arrives at the parking space and is ready to start charging, the user selects to swipe the card through the operation screen 2 to unlock the charging gun seat, and the charging pile switches from the standby state to the ready-to-charge state; the user removes the charging gun head 8 from the charging gun seat 7; the homing induction sensor 6 on the charging gun seat 7 is activated; the charging pile controller 14 controls the drive motor 11 to start rotating, the rotating device 9 starts to move, and the hidden rail damping wire take-up arm starts to rotate clockwise; when the tension value of the tension induction sensor 4 of the gun line fixing device 13 is greater than the 60N threshold The driving motor 11 continues to rotate until the tension value of the tension sensing sensor 4 is less than or equal to 60N, or the value of the angular displacement sensing sensor 10 is greater than or equal to 90 degrees, the driving motor 11 stops rotating, and the angular displacement sensor 10 transmits the angle value back to the charging controller 14 for closed-loop control; at this time, when the tension value is greater than 40N, the hidden guide rail slides out quickly to support the tension of the remaining part of the gun line (when the tension value is less than 40N, the hidden guide rail does not need to be drawn out); the user plugs the charging gun head 8 into the charging vehicle to start charging.

[0046] When the user has finished charging, the user pulls out the charging gun head 8 from the vehicle. When the user brings the gun head back to the charging gun seat, the hidden rail on the hidden guide rail damping take-up arm is quickly retracted (if extended) and buffered; the charging controller controls the drive motor 11 to start reversing, and the hidden guide rail damping take-up arm starts to automatically retract back; when the value of the angular displacement sensing sensor 10 is less than or equal to 0 degrees and the tension value of the tension sensing sensor 4 is less than or equal to 20N, the drive motor 11 automatically stops moving, and the hidden guide rail damping take-up arm stops rotating; the user inserts the charging gun head 8 back into the charging gun seat 7, and after the homing sensing sensor 6 senses that the gun head has returned to its position, the charging controller 14 settles the charging fee with the user. After the settlement is completed, the charging pile 1 returns to the standby state, and the user starts the vehicle and leaves.

[0047] The embodiment of the present application proposes a single rocker arm wire support device and a control method thereof. In the single rocker arm wire support device, one end of the single rocker arm is connected to a rotating device arranged at the bottom of the charging device, and the other end is connected to the charging gun wire, so that when the charging gun wire is dragged, it can be fully extended in the dragging direction under the support of the single rocker arm, thereby minimizing the waste of gun wire length.

[0048] The single rocker arm has two degrees of freedom, one is the rotational degree of freedom, and the other is the telescopic degree of freedom. It can be rotated by the driving motor, thereby driving the charging gun line to automatically rotate in the direction of being dragged. It supports the weight of the charging gun line during the rotation process, thereby minimizing the effort required to drag the charging gun line, achieving the purpose of automated dragging and labor saving. In addition, the single rocker arm itself also has the telescopic degree of freedom, which can further support the charging gun line to move further in the direction of dragging, increase the support range, and achieve the purpose of supporting the charging gun line throughout the entire process of being dragged, minimizing the effort spent on dragging the charging gun line.

[0049] The single rocker arm structure of the present application is streamlined, occupies little space, has strong supporting capacity, is low in cost, and supports the charging gun line throughout the entire process, thereby maximizing the reduction of the effort required to drag the charging gun line, and there is almost no waste of gun line length.
