Description

Technical Field

[0001] This application relates to the technical field of charging piles, and particularly to a single swing arm wire supporting device and its control method. Background Art

[0002] With the increasing number of electric vehicles and the growing demand for vehicle charging, the number and power demand of charging piles are also increasing continuously. In this demand situation, the convenience and intelligence of using charging guns are becoming increasingly important.

[0003] Currently, the charging guns 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 line, and even cannot lift the charging gun due to the excessive weight of the gun line.

[0004] In order to reduce the effort spent on dragging the gun line during charging and improve the convenience of dragging the gun line, related technologies have also proposed technical solutions that can support the gun line during gun line dragging. However, some of these technical solutions use a jib to lift the gun line, and some use the cooperation of springs and pulleys to support the gun line. The former results in a waste of gun line length, and the latter not only causes a waste of gun line length but also leads to a complex device structure and high cost, and causes space waste. Summary of the Invention

[0008] The charging pile is provided with a charging gun seat. When the charging gun head is placed in the charging gun seat, the charging gun line naturally hangs down under the support of the charging gun head and the wire fixing device.

[0016] When the tensile force induction sensor detects that the tensile force generated on the charging cable fixing device when the charging cable is dragged is greater than a first tensile force value, the charging controller controls the driving motor to drive the rotation device to rotate, and the included angle between the rotation linear velocity direction of the rotation device and the dragging direction of the charging cable is less than a first angle threshold;

[0017] When the single swing arm rotates driven by the rotation device, the angular displacement sensor detects the rotation angle of the single swing arm;

[0018] When the rotation angle is greater than a second angle threshold or the tensile force detected by the tensile force induction sensor is less than or equal to the first tensile force value, the charging controller controls the driving motor to stop driving the rotation device;

[0019] When the rotation device stops rotating and the tensile force detected by the tensile force induction sensor is greater than or equal to a second tensile force value and less than the first tensile force value, the damping telescopic arm inside the single swing arm slides out until the charging cable extends to the maximum length in the dragging direction or the charging gun head is inserted into the object to be charged.

Specific Embodiments

[0047] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings. It should be noted that all kinds of data used in the embodiments of the present application have been fully authorized by the relevant entities before use.

[0048] Please refer to Figure 1 , which shows a schematic diagram of a single swing arm wire support device provided by an embodiment of the present application under an exemplary embodiment.

[0049] An embodiment of the present application provides a single swing arm wire support device, including a charging pile 1 standing upright on the ground, a charging gun wire 12 extending from the charging pile, and one end of the charging gun wire 12 is fixed to a charging gun head 8. The charging pile 1 in the embodiment of the present application is not limited, and it can be a DC charging pile or an AC charging pile. The position where the charging gun wire extends from the charging pile in the embodiment of the present application is not limited, and it can extend from the top area, middle area or bottom area of the charging pile, and can extend more and more when being dragged until reaching the maximum extension length. The embodiment of the present application does not limit the extension length, which does not constitute an implementation obstacle. The present application does not limit the sizes of the top area, middle area or bottom area, which only represent the relative position relationship between them. 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 charges by inserting into the object to be charged, such as the charging port of a charging vehicle.

[0050] At the bottom area of the charging pile, there is a rotating device 9 and a driving motor 11 connected to the rotating device 9. The rotating device 9 is connected to a single swing arm 5 and is used to drive the single swing arm 5 to rotate under the drive of the driving motor 11. Inside the single swing arm 5, there is a damping telescopic arm, which is used to slide in the inner cavity of the single swing arm. The top of the damping telescopic arm is fixed at a preset position of the charging gun line 12 through a gun line fixing device 13. The embodiments of the present application do not limit this preset position. It can be a reasonable connection position between the gun line fixing device 13 and the charging gun line 12 when the charging gun line 12 can be maximally extended in the dragged direction, and at this time, the damping telescopic arm of the single swing arm completely slides out of the inner cavity. This position can be measured through experiments or set according to experience, without constituting an implementation obstacle. The driving motor 11 can be manually triggered or automatically triggered. In the case of manual triggering, the user can independently control the rotation of the rotating device. The rotating device 9 and the single swing arm 5 are arranged in the bottom area of the charging pile, which can maximize the saving of the gun line length, so that it can basically be used to extend towards the charging port of the charging vehicle, saving more gun line than the jib structure and the suspension structure.

[0051] The single swing arm 5 in the embodiments of the present application can have two degrees of freedom, one is the rotational degree of freedom and the other is the telescopic degree of freedom. Driven by the driving motor, it can rotate and also has its own telescopic degree of freedom. Through telescoping, it can further support the charging gun line to move further along the dragging direction. In an exemplary embodiment, the single swing arm 5 can be simply referred to as a hidden guide rail damping telescopic arm. By using the hidden guide rail, the occupied space of the single swing arm is reduced and its extension ability is increased. By reasonably configuring the damping, the process of dragging and recycling the charging gun line is made stable, improving the user experience.

[0052] The charging pile 1 is provided with a charging gun seat 7. When the charging gun head is placed in the charging gun seat 7, the charging gun line 12 naturally hangs down under the support of the charging gun head 8 and the gun line fixing device 13.

[0053] In one embodiment, the charging gun seat 7 is connected to a home position induction sensor 6, and the home position induction sensor 6 is used to detect whether the charging gun head 8 is placed in the charging gun seat 7;

[0054] The rotating device 9 is connected to an angular displacement sensor 10, and the angular displacement sensor 10 is used to detect the rotation angle of the single swing 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 swing arm 5 is the same as the dragged direction. That is to say, the movement of the charging gun line in the dragged direction is supported by rotation.

[0055] The gun line fixing device 13 is connected to the tensile force induction sensor 4, and the tensile force induction sensor 4 is used to detect the tensile force generated on the gun line fixing device 13 when the charging gun line 12 is dragged. When the gun line is dragged and moves along the dragging direction, it will drive the single swing arm 5, thereby generating a tensile force on the gun line fixing device 13 of the single swing arm 5, and this tensile force is detected by the tensile force induction sensor 4.

[0056] The home position induction sensor 6, the angular displacement sensor 10, and the tensile force induction sensor 4 are all connected to the charging controller 14 provided on the charging pile 1. The charging controller 14 is used to control the rotation of the single swing arm 5 and the energization 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 tensile force induction sensor 4, and the home position induction sensor 6 can all be obtained by the charging controller 14 in a timely manner, and no further elaboration is made here.

[0057] In one embodiment, the charging pile 1 is further provided with an operation screen 2 and a card swiper 3. The card swiper 3 and the operation screen 2 are both communicatively connected to the charging controller 14. The card swiper 3 is used to detect the user's card swiping information, the operation screen 2 is used to receive the user's instructions, and the charging controller 14 is further used to control the rotation of the single swing arm 5 and the energization of the charging gun head 8 when the card swiping information meets the charging requirements.

[0058] In the embodiment of the present application, the working principle of the single swing arm wire supporting device can be summarized as follows:

[0059] When the charging gun head has not left the charging gun seat, it is in a standby state, and the hidden guide rail damping wire retracting arm is in the initial position. As Figure 1 can be seen, 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 above the charging gun seat and starts the drive motor, and the hidden guide rail damping wire retracting arm automatically starts to rotate. As Figure 2 shown, it shows the single swing arm rotation schematic diagram of the embodiment of the present application. At this time, the damping telescopic arm of the hidden guide rail damping wire retracting arm is hidden in the internal space.

[0060] As Figure 3 shown, it shows the single swing arm telescopic schematic diagram of the embodiment of the present application. Manually pull the charging gun line to start moving towards the vehicle charging socket. When the tensile force detected by the tensile force induction sensor 4 is small, it can be determined that rotation is no longer required, and it is very likely that the charging port is almost reached. At this time, the drive motor stops rotating and returns the rotation angle detected by the angular displacement sensor. If the user continues to pull the gun line, the hidden guide rail damping wire retracting arm quickly slides out automatically to reach a length that balances the gun line tensile force, and the user can easily insert the charging gun head into the charging vehicle to start charging.

[0061] After charging is completed, the user pulls out the charging gun head from the vehicle. During the process of retracting the charging gun head, the guide rail type damping wire retracting arm quickly retracts and hides, and buffers the damping when in place. If the rotation direction of the rotating device during the process of pulling the charging wire for charging is regarded as forward rotation, then at this time, the driving motor drives the rotating device to reverse, that is, to rotate the guide rail type damping wire retracting arm. After the charging gun head is inserted back into the charging gun seat, the guide rail type damping wire retracting arm returns to the standby state.

[0062] Please refer to Figure 4 , which shows the flowchart of the control method for the wire supporting device according to the embodiment of the present application. The method is applied to the aforementioned single swing arm wire supporting device, and the method includes:

[0063] S401. When the home position induction sensor 6 detects that the charging gun head 8 leaves the charging gun seat 7, the charging controller 14 triggers the driving motor 11 to start;

[0064] S402. When the pulling force induction sensor 4 detects that the pulling force generated on the gun wire fixing device 13 when the charging gun wire 12 is dragged is greater than the first pulling force value, the charging controller 14 controls the driving motor 11 to drive the rotating device 9 to rotate, and the included angle between the rotational linear velocity direction of the rotating device 9 and the dragging direction of the charging gun wire 12 is less than the first angle threshold;

[0065] The meaning that the included angle between the rotational linear velocity direction of the rotating device 9 and the dragging direction of the charging gun wire 12 is less than the first angle threshold is that the single swing arm can rotate along the direction that can support the charging gun wire in the dragging direction, and this first angle threshold can be less than 10 degrees. Taking Figure 2 as an example, the rotating device 9 rotates in the clockwise direction.

[0066] S403. When the single swing arm 5 rotates driven by the rotating device 9, the angular displacement sensor 10 detects the rotation angle of the single swing arm 5.

[0067] Taking Figure 1 as an example, the single swing arm is vertically upward in the standby state. When the charging gun wire is pulled towards the object to be charged, the single swing arm rotates clockwise, and the angle formed between the position after rotation and the vertically upward standby position is the rotation angle. During the charging gun wire recovery stage, the angle formed between the actual position of the single swing arm 5 and the vertically upward standby position is still the rotation angle.

[0068] S404. When the rotation angle is greater than the second angle threshold or the pulling force detected by the pulling force induction sensor 4 is less than or equal to the first pulling force value, the charging controller 14 controls the driving motor 11 to stop driving the rotating device 9;

[0069] S405. When the rotation device 9 stops rotating and the pulling force detected by the pulling force sensor 4 is greater than or equal to the second pulling force value and less than the first pulling force value, the damping telescopic arm inside the single swing arm 5 slides out until the charging gun cable 12 extends to the maximum length in the dragged direction or the charging gun head 8 is inserted into the object to be charged.

[0070] The embodiments of the present application do not limit the first pulling force value, the second pulling force value, and the second angle threshold. Exemplarily, the first pulling force value is greater than or equal to 50 Newtons and less than or equal to 70 Newtons, the second pulling force 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 pulling force value is 50 Newtons, the second pulling force value is 30 Newtons, and the second angle threshold is 90 degrees. In another embodiment, the first pulling force value is 70 Newtons, the second pulling force value is 45 Newtons, and the second angle threshold is 85 degrees.

[0071] In an exemplary embodiment, after the damping telescopic arm inside the single swing arm 5 slides out, it may continue to trigger the rotation of the single swing arm and the continuous sliding out of the damping telescopic arm after the rotation stops, including:

[0072] During the process of the damping telescopic arm sliding out, if the pulling force sensor 4 detects that the pulling force is greater than the first pulling force value and the rotation angle is less than the second angle threshold, the charging controller 14 controls the drive motor 11 to drive the rotation device 9 to continue rotating; when the single swing arm 5 rotates driven by the rotation device 9, the angular displacement sensor 10 detects the rotation angle of the single swing arm 5; when the rotation angle is greater than the second angle threshold or the pulling force detected by the pulling force sensor 4 is less than or equal to the first pulling force value, the charging controller 14 controls the drive motor 11 to stop driving the rotation device 9. When the rotation device 9 stops rotating and the pulling force detected by the pulling force sensor 4 is greater than or equal to the second pulling force value and less than the first pulling force value, the damping telescopic arm inside the single swing arm 5 continues to slide out. This process repeats until the charging gun cable 12 extends to the maximum length in the dragged direction or the charging gun head 8 is inserted into the object to be charged.

[0073] After charging is completed, the method further includes: when the home position induction sensor 6 detects that the charging gun head 8 is placed in the charging gun seat 7, the charging controller 14 controls the drive motor 11 to drive the rotation device 9 to rotate in the reverse direction; this reverse rotation is relative to the rotation direction before charging. Continuing with the previous example, it can rotate counterclockwise at this time.

[0074] The angular displacement sensor 10 detects the rotation angle of the single swing 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 wire winding is basically completed and reverse rotation is not required. The embodiments of the present application do not limit the third angle threshold, which can be less than or equal to 10 degrees, for example, it can be zero degrees.

[0075] In one embodiment, when the home position 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 retracted and hidden in the inner cavity of the single swing arm 5. The expansion and contraction of the damping telescopic arm depends on the damping sliding structure of the single swing arm itself and does not require electric control, so the embodiments of the present application will not elaborate.

[0076] In another embodiment, before the home position induction sensor 6 detects that the charging gun head 8 leaves the charging gun seat 7, the card swiping information detected by the card swiper 3 meets the charging requirements; the embodiments of the present application do not overly limit the card swiping information meeting the charging requirements and do not constitute an implementation obstacle. After the home position induction sensor 6 detects that the charging gun head 8 is placed on the charging gun seat 7, the operation screen 2 displays preset information indicating that the charging is completed.

[0077] In a specific embodiment, please refer to Figure 5 , which shows the control method architecture block diagram of the embodiments of the present application.

[0078] When the charging vehicle arrives at the parking space and starts to prepare for charging, the user selects card swiping through the operation screen 2 to unlock the charging gun seat, and the charging pile switches from the standby state to the charging preparation state; the user removes the charging gun head 8 from the charging gun seat 7; the home position 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 operate, and the hidden guide rail damping wire winding arm starts to rotate clockwise; when the tensile force value of the tensile force sensor 4 of the gun wire fixing device 13 is greater than the 60N threshold, the drive motor 11 continues to rotate until the tensile force value of the tensile force sensor 4 is less than or equal to 60N, or when the value of the angular displacement sensor 10 is greater than or equal to 90 degrees, the drive 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 tensile force value is greater than 40N, the hidden guide rail slides out quickly to support the tensile force of the remaining part of the gun wire (when the tensile force value is less than 40N, the hidden guide rail does not need to slide out); the user plugs the charging gun head 8 into the charging vehicle to start charging.

[0079] When the user finishes charging, the user pulls out the charging gun head 8 from the vehicle. During the process of the user taking the gun head back to the charging gun seat, the hidden guide rail on the hidden guide rail damping wire winding arm quickly retracts (if extended) and cushions the retraction; the charging controller controls the drive motor 11 to start rotating in reverse, and the hidden guide rail damping wire winding arm starts to automatically retract; when the value of the angular displacement induction sensor 10 is less than or equal to 0 degrees and the pulling force value of the pulling force induction sensor 4 is less than or equal to 20 N, the drive motor 11 automatically stops operating, and the hidden guide rail damping wire winding arm stops rotating; the user inserts the charging gun head 8 back into the charging gun seat 7. After the homing induction sensor 6 senses that the gun head is in place, 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.

[0080] The embodiment of the present application proposes a single swing arm wire supporting device and its control method. In the single swing arm wire supporting device, one end of the single swing 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 swing arm, minimizing the waste of the gun wire length to the greatest extent.

[0081] The single swing arm has two degrees of freedom, one is the rotational degree of freedom and the other is the telescopic degree of freedom. Driven by the drive motor, it can rotate, thereby driving the charging gun wire to automatically rotate in the dragged direction. It supports the weight of the charging gun wire during its rotation process, thus minimizing the effort required to drag the charging gun wire to the greatest extent and achieving the purpose of automated and labor-saving dragging. Moreover, the single swing arm itself also has a telescopic degree of freedom. Through telescoping, it can further support the charging gun wire to move further along the dragging direction, increasing the support range, and achieving the purpose of supporting the charging gun wire throughout the process of being dragged and minimizing the effort required to drag the charging gun wire to the greatest extent.

[0082] The single swing arm structure of the present application is concise, occupies a small space, has strong supporting ability, low cost, and achieves the purpose of supporting the charging gun wire throughout the process, maximizing the reduction of the effort required to drag the charging gun wire. Moreover, there is almost no waste of the gun wire length, with a delicate concept and high practicality.
