Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to an intelligent billing management device for new energy vehicle charging piles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the popularity of electric vehicles is constantly increasing, and the construction scale of charging piles as supporting infrastructure is also continuously expanding. However, it is very common for charging spaces to be occupied for a long time by fuel vehicles or new energy vehicles that have already finished charging.

[0003] Because existing charging stations lack effective physical locking mechanisms, users can freely use the charging gun without paying, preventing vehicles with genuine charging needs from using the charging stations. This severely reduces the turnover efficiency and utilization rate of charging stations. Furthermore, existing charging cables are typically quite heavy. When the charging gun is inserted into the vehicle's charging port, the downward weight of the cable directly affects the connection point of the charging head. Under prolonged charging or when subjected to external force, the charging head is prone to bending and deformation, or even accidentally detaching from the charging port. This not only affects the user experience but may also cause electrical safety accidents. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent billing and management device for new energy vehicle charging piles. It solves the technical problem that existing charging piles lack an effective physical locking mechanism and cannot effectively prevent vehicles from occupying the charging space. The device has the advantages of effectively preventing vehicles from occupying the charging space, ensuring a stable charging connection, and realizing automatic cable tensioning management.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a smart billing management device for new energy vehicle charging piles, including a charging pile body, a rain shelter on the top of the charging pile body, an anti-occupancy locking mechanism and a cable tensioning mechanism on the side of the charging pile body, the anti-occupancy locking mechanism being used to lock the charging gun body after charging is completed to prevent vehicles from occupying the space, the cable tensioning mechanism being used to maintain the cable taut and prevent damage from being stepped on or crushed, the anti-occupancy locking mechanism including a rotary joint, a charging cable being fixedly installed on the rotary joint, a charging gun body being fixedly installed at the end of the charging cable away from the rotary joint, a gripping groove being opened through the charging gun body, a gun head receiving groove being opened on the side of the charging pile body, a support boss being provided below the gun head receiving groove, two mounting bases being symmetrically installed on the support boss, and an electromagnetic limiting component being movably installed on the mounting base, under normal conditions, the head of the charging gun body will be located inside the gun head receiving groove, the support boss will support the charging gun body, and the electromagnetic limiting component will be inserted into the gripping groove.

[0006] Preferably, the electromagnetic limiting component includes an electromagnetic sleeve fixedly installed on the mounting base, and a telescopic locking tongue slidably installed inside the electromagnetic sleeve. One end of the telescopic locking tongue is connected to the inner wall of the electromagnetic sleeve by a return spring, and the other end of the telescopic locking tongue is inserted into the gripping groove when extended, thereby preventing the charging gun body from being removed at will.

[0007] Preferably, the upper surface of the support boss is provided with a positioning groove that matches the contour of the end of the charging gun body. A placement sensor is provided in the positioning groove to detect whether the charging gun body is placed in place. After being placed in place, the telescopic locking tongue will automatically extend and insert into the inside of the gripping through groove, thereby completing the locking action of the charging gun body.

[0008] Preferably, the charging pile body is equipped with a touch screen component and a speaker. The touch screen component is electrically connected to the billing control module inside the charging pile body. The touch screen component is used to display charging fees and QR code information. Users can use the touch screen component to select charging packages and make payments.

[0009] Preferably, the side of the charging pile body is also provided with an anti-detachment support mechanism. The anti-detachment support mechanism includes a fixed ring seat that is fixedly sleeved on the outside of the charging cable. Support rods are symmetrically installed on the fixed ring seat. A rubber suction cup is installed at the end of the support rod away from the fixed ring seat. The rubber suction cup can be quickly adsorbed and fixed to the vehicle body near the charging port, thereby providing triangular support for the charging cable.

[0010] Preferably, the support rod is hinged to the fixed ring seat, and the outer side of the fixed ring seat is provided with an avoidance groove, so that the support rod can rotate within a certain range.

[0011] Preferably, a guide slider is slidably connected to the fixed ring seat, a limit protrusion is fixedly installed on the guide slider, and a limit groove is opened on the hinge shaft of the support rod. After the limit protrusion is inserted into the limit groove, it will restrict the rotation of the support rod.

[0012] Preferably, the cable tensioning mechanism includes a vertical slide rail vertically installed on the side wall of the charging pile body, a rectangular slide table slidably installed on the vertical slide rail, a mounting shaft fixedly installed on the rectangular slide table, and a tensioning wheel for supporting the charging cable rotatably installed on the mounting shaft. The tensioning wheel always tends to move downward under its own weight, thereby pressing the charging cable downward to keep it taut.

[0013] By employing the above technical solution, the present invention provides an intelligent billing management device for new energy vehicle charging piles, which has at least the following beneficial effects: 1. This invention features an anti-occupancy locking mechanism. The retractable locking tongue will only retract and unlock after the user completes payment on the touch screen component, physically preventing unpaid users from taking the charging gun at will. This design effectively prevents fuel vehicles or other non-charging vehicles from occupying the charging space, ensuring that charging pile resources truly serve users with charging needs.

[0014] 2. This invention, by setting up an anti-occupancy locking mechanism, allows the sensor to immediately detect the return status when the user puts the charging gun back on the support boss after charging is complete. It also automatically controls the electromagnetic sleeve to cut off the power, allowing the telescopic locking tongue to re-insert into the gripping slot under the action of the return spring to complete the locking. No manual operation or additional confirmation is required, achieving fully automatic locking management. This not only avoids equipment damage caused by the user forgetting to put the charging gun back, but also ensures that the charging gun can enter the anti-occupancy state in a timely manner after each charging.

[0015] 3. By setting up an anti-detachment support mechanism, the present invention utilizes the cooperation between the rubber suction cup and the support rod. The user can attach the rubber suction cup to the flat paint surface near the charging port of the vehicle body, forming a triangular support structure together with the charging cable. This design can share the weight of the cable falling on the charging head, and prevent the charging head from bending or deforming due to excessive cable weight or external pulling, or from accidentally detaching from the vehicle charging port. This can effectively ensure the continuity and stability of the charging process.

[0016] 4. By setting up an anti-detachment support mechanism, the support rod and the fixed ring seat are hinged and provided with a clearance groove, so that the support rod can rotate freely within a certain range. This allows users to adjust the adsorption posture according to the charging port position and body curvature angle of different car models, greatly improving the adaptability and stability on various complex car bodies.

[0017] 5. This invention utilizes a cable tensioning mechanism based on the principle of gravity self-adjustment. When the charging cable is slack, the tensioning wheel will automatically drop to straighten it. When the charging cable is pulled out, the tensioning wheel will be lifted and ready to drop to tighten it. This dynamic tensioning mechanism ensures that the charging cable is always taut, effectively preventing it from being run over by vehicles or stepped on by pedestrians after falling to the ground, and greatly reducing the risk of cable sheath wear and internal wire breakage.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Existing charging stations lack effective physical locking mechanisms, allowing users to freely use charging guns without paying. This prevents vehicles with genuine charging needs from accessing the charging stations, severely reducing their turnover efficiency and utilization rate. To address this technical deficiency in existing technologies, such as... Figures 1-5As shown in the figure, this embodiment proposes an intelligent billing management device for new energy vehicle charging piles, which can effectively prevent vehicles from occupying the charging position, ensure the stability of the charging connection, and realize automatic cable tensioning management. The device includes a charging pile body 1, a rain shelter 2 is provided on the top of the charging pile body 1, and an anti-occupation locking mechanism 3 and a cable tensioning mechanism 5 are provided on the side of the charging pile body 1. The anti-occupation locking mechanism 3 is used to lock the charging gun body 303 after charging is completed to prevent vehicles from occupying the position. The cable tensioning mechanism 5 is used to maintain the cable in a taut position to avoid damage from being stepped on or crushed.

[0022] Specifically, the anti-occupancy locking mechanism 3 includes a rotary joint 301, on which a charging cable 302 is fixedly installed. A charging gun body 303 is fixedly installed at the end of the charging cable 302 away from the rotary joint 301. A gripping groove 304 is formed through the charging gun body 303. A gun head receiving groove 305 is formed on the side of the charging pile body 1. A support boss 306 is provided below the gun head receiving groove 305. A positioning groove matching the end contour of the charging gun body 303 is formed on the upper surface of the support boss 306. A placement sensor is provided in the positioning groove to detect whether the charging gun body 303 is in place. After placement, the telescopic locking tongue automatically extends and inserts into the gripping groove 304, thereby completing the locking action of the charging gun body 303. Two mounting bases 307 are symmetrically installed on the support boss 306. An electromagnetic limiter 308 is movably installed on the mounting base 307. Under normal conditions, the head of the charging gun body 303 is located inside the gun head receiving groove 305. The supporting boss 306 supports the charging gun body 303. The electromagnetic limiting member 308 is inserted into the gripping through groove 304. The electromagnetic limiting member 308 includes an electromagnetic sleeve fixedly installed on the mounting base 307 and a telescopic locking tongue slidably installed inside the electromagnetic sleeve. One end of the telescopic locking tongue is connected to the inner wall of the electromagnetic sleeve with a return spring. The other end of the telescopic locking tongue is inserted into the gripping through groove 304 when extended, thereby preventing the charging gun body 303 from being removed arbitrarily. The charging pile body 1 is equipped with a touch screen component 309 and a speaker 310. The touch screen component 309 is electrically connected to the billing control module inside the charging pile body 1. The touch screen component 309 is used to display charging fees and QR code information. Users can use the touch screen component 309 to select and pay for charging packages.

[0023] As can be seen from the above, the charging pile body 1 is equipped with a billing management controller, which is electrically connected to the electromagnetic limiter 308, the touch screen assembly 309 and the speaker 310 respectively.

[0024] Before charging begins or after charging is complete, the head of the charging gun body 303 will be located in the gun head receiving groove 305. Before the user completes the selection and payment of the charging package, the electromagnetic limiter 308 will keep the charging gun body 303 locked.

[0025] When the user completes the charging package selection and payment on the touch screen component 309, and the billing management controller confirms the payment is successful, it will send a command to the electromagnetic limit component 308. Subsequently, the telescopic locking tongue will retract under the action of the electromagnetic sleeve, thereby releasing the limiting effect on the charging gun body 303.

[0026] After charging is complete, the user will put the charging gun body 303 back into the support boss 306 and position the head of the charging gun body 303 inside the gun head receiving groove 305. At this time, the placement sensor will detect that the charging gun body 303 has been returned to its original position.

[0027] Next, the electromagnetic sleeve will lose power and magnetism, and the telescopic locking tongue will be inserted into the gripping slot 304 under the action of the return spring, thereby relocking the charging gun body 303.

[0028] This embodiment features an anti-occupancy locking mechanism 3. The telescopic latch will only retract and unlock after the user completes payment on the touchscreen component 309, physically preventing unpaid users from taking the charging gun at will. This design effectively prevents fuel vehicles or other non-charging vehicles from occupying the charging space, ensuring that charging pile resources truly serve users with charging needs. Moreover, by setting up the anti-occupancy locking mechanism 3, when the user returns the charging gun body 303 to the support boss 306 after charging, the placement sensor can immediately detect the return status and automatically control the electromagnetic sleeve to cut off the power. This allows the telescopic latch to re-insert into the gripping slot 304 under the action of the return spring, completing the locking process without manual operation or additional confirmation. This achieves fully automatic locking management, preventing equipment damage caused by users forgetting to return the charging gun body 303 and ensuring that the charging gun body 303 promptly enters the anti-occupancy state after each charging session.

[0029] Example 2 In existing technology, after the charging gun of a charging station is inserted into the vehicle's charging port, the weight of the cable directly acts on the gun head connection. During prolonged charging or under external pulling force, the gun head is prone to bending and deformation, and may even accidentally detach from the charging port. This not only affects the user experience but may also cause electrical safety accidents. To address this technical deficiency, based on Embodiment 1, as follows... Figure 1 , Figure 2 , Figure 5 , Figure 6 as well as Figure 7As shown, this embodiment includes an anti-detachment support mechanism 4. Specifically, the anti-detachment support mechanism 4 includes a fixed ring seat 401 fixedly sleeved on the outside of the charging cable 302. Support rods 402 are symmetrically installed on the fixed ring seat 401. A rubber suction cup 403 is installed at the end of the support rod 402 away from the fixed ring seat 401. The rubber suction cup 403 can quickly adhere and fix to the car body near the charging port, thereby providing triangular support for the charging cable 302. The support rod 402 is hinged to the fixed ring seat 401. An avoidance groove 404 is provided on the outside of the fixed ring seat 401, so that the support rod 402 can rotate within a certain range. A guide slider 405 is slidably connected to the fixed ring seat 401. A limiting protrusion 406 is fixedly installed on the guide slider 405. A limiting groove is provided on the hinge shaft of the support rod 402. After the limiting protrusion 406 is inserted into the limiting groove, it will restrict the rotation of the support rod 402.

[0030] As can be seen from the above, after the user inserts the charging gun body 303 into the car charging port, he / she rotates the two support rods 402 until the rubber suction cups 403 at the ends of the support rods 402 can be firmly attached to the smooth paint surface of the car body near the car charging port.

[0031] After the angle adjustment is completed, the user will press the guide slider 405, so that the limiting protrusion 406 is inserted into the limiting groove on the hinge shaft, thereby locking the angle of the support rod 402 and ensuring that the rubber suction cup 403 can maintain a stable adsorption state throughout the charging process.

[0032] After the rubber suction cup 403 is attached and fixed, the support rod 402 and the charging cable 302 will form a triangular support structure together. This structure can effectively share the weight of the cable falling on the charging gun body 303, and prevent the gun head from bending or coming out of the charging port due to excessive cable weight.

[0033] This embodiment, by setting up an anti-detachment support mechanism 4, utilizes the cooperation between the rubber suction cup 403 and the support rod 402. The user can attach the rubber suction cup 403 to a flat painted surface near the vehicle's charging port, forming a triangular support structure together with the charging cable 302. This design can share the weight of the cable falling on the charging head, preventing the charging head from bending or deforming due to excessive cable weight or external pulling, or from accidentally detaching from the vehicle's charging port, effectively ensuring the continuity and stability of the charging process. Moreover, by setting up the anti-detachment support mechanism 4, the support rod 402 is hinged to the fixed ring seat 401 and has a clearance groove 404, allowing the support rod 402 to rotate freely within a certain range. This allows the user to adjust the suction posture according to the charging port position and vehicle surface curvature of different models, greatly improving adaptability and stability on various complex vehicle bodies.

[0034] Example 3 To prevent the charging cable 302 from being run over by vehicles or stepped on by pedestrians after falling to the ground, based on the above embodiments, such as Figures 1-3 As shown, this embodiment includes a cable tensioning mechanism 5. Specifically, the cable tensioning mechanism 5 includes a vertical slide rail 501 vertically mounted on the side wall of the charging pile body 1. A rectangular slide table 502 is slidably mounted on the vertical slide rail 501. A mounting shaft 503 is fixedly mounted on the rectangular slide table 502. A tensioning wheel 504 for supporting the charging cable 302 is rotatably mounted on the mounting shaft 503. The tensioning wheel 504 always tends to move downward under its own weight, thereby pressing the charging cable 302 downward to keep it taut.

[0035] As can be seen from the above, the rectangular slide table 502 and the tensioning wheel 504 do not have any additional locking or power devices. Therefore, under their own weight, they will always have the tendency to slide downward along the vertical slide rail 501. The charging cable 302 is located below the tensioning wheel 504. When the charging cable 302 is in a slack state, the tensioning wheel 504 will slide downward under the action of gravity, pulling down the excess slack part of the charging cable 302, thereby keeping the charging cable 302 in a taut and straight state.

[0036] When the user pulls the charging cable 302 to charge, the charging cable 302 will overcome the gravity of the tensioning wheel 504 and lift it up along the vertical slide rail 501. At this time, the rectangular slide 502 will rise accordingly. No matter how long the charging cable 302 is pulled out, as long as the external tension decreases, the tensioning wheel 504 will immediately fall down by gravity and tighten the charging cable 302 again. This design allows the charging cable 302 to always be attached to the tensioning wheel 504, which can effectively prevent the charging cable 302 from falling to the ground and being run over by vehicles or stepped on by pedestrians.

[0037] In this embodiment, by setting up a cable tensioning mechanism 5, the tensioning wheel 504 automatically falls to straighten the charging cable 302 when it is slack. When the charging cable 302 is pulled out, the tensioning wheel 504 is lifted up and ready to fall to tighten it at any time. This dynamic tensioning mechanism can ensure that the charging cable 302 is always in a taut state, which can effectively prevent the charging cable 302 from being run over by vehicles or stepped on by pedestrians after it falls to the ground, and greatly reduce the risk of cable sheath wear and internal wire breakage.

[0038] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0039] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
