Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to an intelligent charging pile. Background Art

[0002] With the popularization of new energy vehicles, charging piles, as important supporting facilities for new energy vehicles, are also being built rapidly to meet the increasing use requirements of new energy vehicles.

[0003] Existing charging piles typically include a main power module, charging connector, cable, control board, metering and billing module, human-machine interface, safety protection system, power supply and distribution module, cooling system, housing, and structural components. Existing charging piles also offer DC and AC charging modes, equipped with corresponding DC and AC charging cables.

[0004] In the prior art, Chinese patent publication number CN112429599B discloses an AC charging pile with a wire-reeling structure, which discloses a folding and winding method of the charging cable by the wire-reeling mechanism, replacing the traditional wrap-around winding method. This method can prevent the charging cable from wrinkling and aging, and loosening of internal connections during long-term winding.

[0005] In combination with the above-mentioned existing technology, the technical effect to be achieved is to store the cables to prevent them from being damaged. However, the storage of the cables still requires manual rotation of the take-up hand wheel, which is inconvenient in actual use.

[0006] For another example, in the prior art, a Chinese patent with publication number CN216069675U discloses an automatic wire-reeling smart charging pile, which discloses that a first switch and a second switch can be automatically started and stopped when in use, and a motor can drive a wire-reeling wheel to automatically retract the power cord when in use. The wire-reeling efficiency is high during use, and a cleaning sponge on the surface of the wire-reeling wheel can clean the power cord during reeling, which can prevent stains from adhering to the power cord during use, thereby increasing the service life of the power cord, and the effect of use is better than that of the traditional method.

[0007] In combination with the above-mentioned existing technology, although a motor is used to drive the cable for automatic reeling, part of the cable will rub against the ground during the reeling process, and even the charging gun will rub against the ground. Over time, the insulation layer on the cable surface and the charging gun casing will produce varying degrees of wear, affecting the electrical performance of the cable and the charging gun.

[0008] In summary, existing charging piles have not made comprehensive considerations on the placement and storage of cables, resulting in damage to the surface insulation layer of the cables after long-term repeated dragging, causing safety accidents such as leakage. Secondly, the cable dragging process mainly relies on manual guidance, which makes the direction and scattering of the cables uncontrollable, making them prone to being crushed by wheels, reducing the actual application reliability and flexibility of the charging pile cables. Summary of the Invention

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See also Figures 1 to 8 , an embodiment provided by the present invention:

[0053] See also Figure 1 A smart charging pile includes a pile body 100, multiple wire collection boxes 200, multiple hanging rails 300, multiple rail cars 400, multiple charging guns 500, multiple cables 600 and multiple controllers 700.

[0054] Specifically, multiple controllers 700 are electrically connected to the control main board in the pile body 100 respectively, so as to achieve the effect of monitoring the working status of multiple controllers 700 and corresponding data. The function of the controller 700 is to control the status of the wire collection box 200 and the rail car 400 in the corresponding range, reduce the computing intensity of the control main board in the pile body 100, and reduce the risk of confusion in action logic.

[0055] It is worth noting that the plurality of hanging rails 300 are respectively arranged between two adjacent parking spaces, and the cables 600 arranged in the plurality of hanging rails 300 can be electrically connected to the same pile body 100 .

[0056] The hanging rail 300 is set on the top surface of the rain shelter above the new energy charging parking space, and the charging gun 500 hangs naturally and is located between the new energy parking spaces, which can meet the charging needs of two adjacent parking spaces.

[0057] See also Figure 3 and Figure 6 The cable 600 is located inside the wire receiving box 200, the hanging rail 300, and the rail car 400 respectively. The cable 600 passes through one end of the rail car 400 and is connected to the charging gun 500.

[0058] See also Figure 4The hanging rail 300 is provided with a cable trough 301 connected to the cable receiving box 200. A guide wheel 304 is provided at the connection between the cable trough 301 and the cable receiving box 200. The guide wheel 304 is used to guide the cable 600 from the cable receiving box 200 into the cable trough 301, preventing friction between the outer wall of the cable 600 and the cable receiving box 200, which could damage the insulation layer of the cable 600.

[0059] See also Figure 2 and Figure 3 A winch 220 for winding up the cable 600 is provided in the take-up box 200, and a first motor 230 for driving the winch 220 to rotate is provided in the winch 220. A rotary connector 210 coaxially distributed with the winch 220 is provided in the take-up box 200. The cable 600 passes through the winch 220 and is connected to the rotary connector 210. A wiring harness 110 is respectively connected between the pile body 100 and the rotary connector 210.

[0060] It is worth noting that the first motor 230 is electrically connected to the controller 700 , and the controller 700 can be used to control the working state of the first motor 230 , including the speed, number of rotations, and rotation direction.

[0061] The plug and socket of the rotary connector 210 can rotate around a common axis and ensure circuit connection, which belongs to mature existing technology and will not be described in detail here.

[0062] Specifically, the pile body 100 is connected to the rotary connector 210 through the wire harness 110 , and the output end of the rotary connector 210 is connected to the cable 600 . The rotary connector 210 satisfies the relative rotation between the wire harness 110 and the cable 600 , and satisfies the effect of rotating and storing the cable 600 through the winch 220 .

[0063] When the first motor 230 drives the winch 220 to rotate, the cable 600 can be wound around the outside of the winch 220 to achieve the purpose of storing the cable 600; secondly, when the first motor 230 reverses, the cable 600 can be released from the outside of the winch 220, and the cable 600 can enter the cable groove 301 from the wire box 200, meeting the needs of the cable 600 extending out of the rail car 400 and the charging gun 500 to connect with the charging port of the new energy vehicle.

[0064] Specifically, when the rail car 400 moves, changes the hanging position of the cable 600, or the conveying mechanism 420 releases the cable 600, changes the height of the charging gun 500, the first motor 230 needs to be reversed to release the cable 600 wound on the winch 220, thereby meeting the release needs of the cable 600.

[0065] See also Figures 5 to 8The rail car 400 includes a driving mechanism 410, a conveying mechanism 420 and a position monitoring mechanism 430. The driving mechanism 410 drives the rail car 400 to move along the hanging rail 300, the conveying mechanism 420 is used to retract and release the cable 600, and the position monitoring mechanism 430 is used to monitor the pulling direction of the cable 600.

[0066] For details, please refer to Figure 4 The hanging rail 300 includes a slide 302 and a rack 303 . The slide 302 is connected to the cable trough 301 , and the rack 303 is distributed below the slide 302 .

[0067] The slideway 302 is used to provide a moving space for the rail car 400 to communicate with the cable duct 301 , and the rack 303 is used to cooperate with the driving mechanism 410 to drive the rail car 400 to move along the hanging rail 300 .

[0068] See also Figure 5 and Figure 6 The driving mechanism 410 includes a pulley 411, a second motor 412, a roller 413 and a gear 414. The roller 413 is arranged in the slideway 302, the pulley 411 is sleeved on the outside of the roller 413, and the pulley 411 can rotate flexibly relative to the roller 413. The cable 600 is arranged on the outside of the pulley 411.

[0069] Specifically, the cable 600 located inside the cable trough 301 is placed on the surface of the pulley 411, and the pulley 411 can flexibly rotate relative to the roller 413, that is, the pulley 411 can guide the cable 600 and guide the cable 600 into the conveying mechanism 420.

[0070] See also Figure 6 Gears 414 are provided at both ends of the roller 413 and mesh with the racks 303. The power output end of the second motor 412 is connected to the roller 413. The second motor 412 is electrically connected to the controller 700, which is used to control the operating state of the second motor 412, including the speed, number of revolutions, and direction of rotation.

[0071] Specifically, when the second motor 412 rotates, it can drive the roller 413 to rotate, and the roller 413 rotates together with the gear 414, so that the gear 414 engages with the rack 303 on the hanging rail 300, thereby driving the rail car 400 to move along the hanging rail 300.

[0072] It is worth noting that see Figure 6 The rail car 400 also includes a plurality of limiting wheels 401 , which are symmetrically distributed on the inner wall of the rail car 400 , and the limiting wheels 401 can rotate along the surface of the hanging rail 300 .

[0073] The limiting wheels 401 are used to limit the rail car 400. The limiting wheels 401 are respectively attached to the upper and lower inner walls of the hanging rail 300, supporting the rail car 400 in the hanging rail 300, so that the driving mechanism 410 can smoothly drive the rail car 400 to move.

[0074] See also Figure 6 and Figure 7 , the conveying mechanism 420 is located below the driving mechanism 410.

[0075] The conveying mechanism 420 includes a driving wheel 421 , a driven wheel 422 , a third motor 423 and a rotary encoder 424 . The power output end of the third motor 423 is connected to the driving wheel 421 , and the driven wheel 422 is connected to the rotary encoder 424 .

[0076] The third motor 423 and the rotary encoder 424 are both electrically connected to the controller 700 , wherein the controller 700 can control the working state of the third motor 423 , including the speed, number of rotations and direction of rotation, thereby accurately controlling the length of the conveying cable 600 conveyed by the conveying mechanism 420 .

[0077] It is worth noting that the rotary encoder 424 can convert the mechanical rotational motion of the driven wheel 422 into a digital signal or a pulse signal, and can measure the rotational speed and angular displacement of the driven wheel 422. The rotary encoder 424 can adopt the RE1103 IC1-H01-0006 model; secondly, the rotary encoder 424 belongs to a mature existing technology, and those skilled in the art can flexibly choose other models according to implementation needs, which will not be elaborated here.

[0078] After the rotary encoder 424 measures the rotation data of the driven wheel 422, it transmits it to the controller 700. The controller 700 performs data calculation to obtain the output length of the cable 600 and the conveying acceleration of the cable 600, which is used by the controller 700 to determine the position state and traction state of the cable 600.

[0079] See also Figure 7 The driving wheel 421 and the driven wheel 422 are respectively in contact with the surface of the cable 600. The driving wheel 421 and the driven wheel 422 respectively clamp the cable 600, and the third motor 423 drives the driving wheel 421 to rotate, and cooperates with the clamping force of the driven wheel 422 on the cable 600 to transport the cable 600.

[0080] It is worth noting that the outer layers of the driving wheel 421 and the driven wheel 422 are both made of rubber material, which has a certain elasticity, and the distance between the driving wheel 421 and the driven wheel 422 is slightly smaller than the diameter of the cable 600. When the driving wheel 421 and the driven wheel 422 are clamped on the outside of the cable 600, they can fit tightly to the outside of the cable 600 and have a certain elasticity, which can be used for elastic buffering to avoid slipping problems.

[0081] Secondly, the driving wheel 421 rotates under the drive of the third motor 423 to transport the cable 600. The driven wheel 422 contacts the cable 600 in the transmission state. The movement of the cable 600 drives the driven wheel 422 to rotate. During this process, the rotary encoder 424 measures the number of rotations, rotation acceleration and rotation angle of the driven wheel 422. Combined with the circumference of the contact position between the driven wheel 422 and the cable 600, the length of the cable 600 passing through the conveying mechanism 420 can be calculated, which is conducive to controlling the output length of the cable 600.

[0082] See also Figure 8 , the position monitoring mechanism 430 is located below the conveying mechanism 420 .

[0083] The position monitoring mechanism 430 includes a first distance sensor 431 and a second distance sensor 432 . The first distance sensor 431 is located on the forward direction side of the railcar 400 , and the second distance sensor 432 is located on the backward direction side of the railcar 400 . The cable 600 is located between the first distance sensor 431 and the second distance sensor 432 .

[0084] The first distance sensor 431 and the second distance sensor 432 are electrically connected to the controller 700 , respectively. The controller 700 is used to process data signals from the first distance sensor 431 and the second distance sensor 432 .

[0085] Specifically, when the cable 600 is in a naturally hanging state, the cable 600 is in a vertical state, and the distances between the outer wall of the cable 600 and the first distance sensor 431 and the second distance sensor 432 are equal.

[0086] When the cable 600 is in an inclined state, a difference will occur in the distances between the outer wall of the cable 600 and the first distance sensor 431 and the second distance sensor 432 .

[0087] It is worth noting that the allowable difference range of the values ​​measured by the first distance sensor 431 and the second distance sensor 432 is half of the diameter of the cable 600 .

[0088] When the difference in values ​​measured by the first distance sensor 431 and the second distance sensor 432 is greater than half the diameter of the cable 600, the cable 600 is triggered to be in a traction tilt state, that is, the rail car 400 is not above the charging port of the new energy vehicle, and the controller 700 controls the rail car 400 to move, and moves the rail car 400 toward the direction of the first distance sensor 431 or the second distance sensor 432 with a smaller monitoring distance value, until the distance values ​​measured by the first distance sensor 431 and the second distance sensor 432 are within the allowable value difference range, then the movement of the rail car 400 is stopped, and the rail car 400 is now above the charging port of the new energy vehicle.

[0089] It is worth noting that see Figure 8 The position monitoring mechanism 430 also includes two limiting rollers 433, which are respectively located on both sides of the first distance sensor 431 and the second distance sensor 432. The cable 600 is located between the two limiting rollers 433, and the width between the two limiting rollers 433 is the same as the diameter of the cable 600.

[0090] The two limiting rollers 433 are used to control the stability of the cable 600 between the first distance sensor 431 and the second distance sensor 432 to ensure the accuracy of the measurement data.

[0091] To sum up, when a new energy vehicle drives to a charging parking space, the user can select the nearest charging gun 500 according to the location of the new energy vehicle charging port. When the charging gun 500 is pulled, the charging gun 500 drives the cable 600 to move, and the rotary encoder 424 detects the acceleration of the cable 600, activating the automatic release program of the cable 600.

[0092] Specifically, after the rotary encoder 424 detects the acceleration of the cable 600, it simultaneously records the number of rotations of the driven wheel 422 and begins measuring the length of the cable 600. Simultaneously, the first distance sensor 431 and the second distance sensor 432 detect the tilt direction of the cable 600. The controller 700 controls the movement of the railcar 400 and the release of the cable 600 by the winch 220. The first motor 230 drives the winch 220 to rotate, releasing the cable 600 from the winch 220 to adjust the length of the cable 600 as the railcar 400 moves.

[0093] The railcar 400 moves toward the direction of the first distance sensor 431 or the second distance sensor 432 where the monitoring distance value is smaller, until the distance values ​​measured by the first distance sensor 431 and the second distance sensor 432 are within the allowable value difference range, then the movement of the railcar 400 is stopped. At this time, the railcar 400 is above the new energy vehicle charging port.

[0094] During this process, the controller 700 controls the third motor 423 to operate, outputting the cable 600. The rotary encoder 424 continuously measures the output length of the cable 600 until it reaches the set length, i.e., the cable 600 extends 2 meters from the railcar 400. During this process, the controller 700 controls the first motor 230 to operate synchronously with the third motor 423, continuously releasing the cable 600 from the capstan 220 to meet the needs of the conveying mechanism 420 for cable transportation.

[0095] If the set length of cable 600 still does not meet actual usage requirements, the user pulls cable 600, and rotary encoder 424 detects acceleration of cable 600 again. Controller 700 then controls conveyor mechanism 420 to deliver 50 cm of cable 600, which is the compensation length. It is worth noting that conveyor mechanism 420 can deliver a maximum of five compensation lengths.

[0096] While the cable 600 is being delivered to the railcar 400, the first motor 230 is in a free-wheeling state. This means that as the railcar 400 moves, the cable 600 can be pulled from the winch 220 for release. This allows the railcar 400 to automatically follow the position of the charging gun 500, reducing the force required to pull the cable and preventing insulation damage from friction between the cable and the ground.

[0097] After charging is completed, the user can disconnect the charging gun 500 from the vehicle charging port. The control motherboard in the pile body 100 cancels the charging state and outputs a reeling signal to the controller 700. The controller 700 outputs a signal to the first motor 230, which drives the winch 220 to rotate and reel in the cable 600.

[0098] During this process, the rotary encoder 424 measures the storage length of the cable 600, which is conducive to controlling the suspension height of the charging gun 500, so that the charging gun 500 is suspended at a height that the user can easily reach, that is, the automatic cable reeling is completed, avoiding the cable 600 from being scattered randomly in the charging parking space, and the risk of damage to the cable 600 caused by being run over by the vehicle, thereby ensuring the reliability and safety of the cable 600.

[0099] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
