Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle charging, specifically relating to a charging gun cable storage device for new energy vehicles. Background Technology

[0002] Electric vehicle charging stations are key infrastructure for providing electric vehicles with power. Their core technologies lie in efficient power conversion, intelligent communication, and safety protection. Modern charging stations have evolved from AC slow charging to supporting high-power DC fast charging and integrating IoT modules to achieve remote monitoring, payment settlement, and load management, helping to build an intelligent, convenient, and safe electric vehicle charging network.

[0003] Patent CN217320061U discloses a new energy vehicle charging gun with a retractable cable, including a storage box, a cable reel, and a cable, one end of which is connected to the charging gun. The cable reel is installed inside the storage box. The cable reel has a storage spring and a slip ring, and the slip ring has a conductive ring and a conductive sheet. When the cable reel rotates, the conductive sheet and the cable reel rotate synchronously, and the conductive sheet slides on the outer surface of the conductive ring while maintaining electrical contact. It also includes a pull-to-stop structure, which includes a limiting gear and a locking tooth. The locking tooth can selectively limit the limiting gear. The limiting gear is an incomplete gear. Thus, by incorporating a slip ring in the reel of the charging gun, the problem of cable breakage during reel rotation is solved. Simultaneously, a pull-and-stop mechanism allows users to pull out the cable as needed and stop it at the appropriate position, greatly facilitating operation. While this device solves the aforementioned problems, the cable still drags on the ground during winding, causing wear on the cable sheath and affecting its lifespan. Furthermore, it poses a safety hazard of electrical leakage and fire. Therefore, a charging gun cable storage device for new energy vehicles is proposed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a charging gun cable storage device for new energy vehicles, so as to solve the problem of reduced cable life caused by cable dragging and wear.

[0005] To achieve the above objectives, the present invention provides a charging gun cable storage device for new energy vehicles, including an electrical box housing, a cable arranged on the inner wall of the electrical box housing, a charging gun arranged on the outer wall of the electrical box housing, a charging gun arranged on the outer wall of the cable, a swing arm device arranged on the top of the electrical box housing, a safety limiting device arranged on the top of the electrical box housing, and a protective heat dissipation mechanism arranged on the inner wall of the electrical box housing. The swing arm device includes a main spring rod, a C-shaped frame, a vertical column, and a horizontal torsion column. The main spring rod is rotatably connected to the inner wall of the electrical box housing via a torsion spring. The C-shaped frame is fixedly connected to the top of the main spring rod. The vertical column is fixedly connected to the inner wall of the C-shaped frame. The horizontal torsion column is rotatably connected to the outer wall of the vertical column. The maximum rotation angle of the main spring rod is 180 degrees. A sensor is installed at the bottom of the electrical box housing.

[0006] In one or more embodiments of the present invention, the swing arm device further includes a helical rod and a drive block. The helical rod is rotatably connected to the inner wall of the transverse torsion column, and the drive block is movably connected to the outer circumferential surface of the helical rod. The drive block is slidably connected to the inner wall of the transverse torsion column, and a motor is provided on the right side of the helical rod.

[0007] In one or more embodiments of the present invention, the swing arm device further includes a traction rope and a fixed ball. The traction rope is fixedly connected to the bottom of the drive block and is slidably connected to the inner wall of the transverse torsion column. The fixed ball is fixedly connected to the bottom of the traction rope and is fixedly connected to the inner wall of the fixed ball and the cable. When charging a vehicle, the charging gun is pulled to the charging port of the trolley, connecting it for charging. As the charging gun is pulled, the cable moves, causing the main spring rod to rotate. This rotation, in turn, rotates the C-frame, which in turn rotates the vertical column, which in turn rotates the horizontal torsion column. This rotation of the horizontal torsion column causes the traction rope to rotate in a circular motion, which in turn rotates the fixed ball. The rotating fixed ball lifts the cable, ensuring it remains suspended throughout the extension process. This prevents friction, crushing, and water damage to the cable's insulation, reduces the risk of leakage, and significantly extends the cable's lifespan. When the device is not in use, the electrical box housing... The sensors in the device receive signals, which in turn transmit signals to the motor, causing it to start automatically. The motor then rotates, and during this rotation, the spiral grooves on the circumferential surface drive the drive block to move under the limit of the transverse torsion column. As the drive block moves, it moves the traction rope at the bottom towards the electrical box housing. The movement of the traction rope moves the fixed ball, which in turn moves the cable towards the electrical box housing. This ensures that when the device is not in use for a long period, the cable will be close to the outer wall of the electrical box housing and coiled up. This prevents the cable from scattering in the air and obstructing pedestrians and animals when not in use, thus reducing safety hazards and minimizing the risk of damage to the device.

[0008] In one or more embodiments of the present invention, the safety limiting device includes a limiting ring, a connecting tooth, and a circumferential ring. The limiting ring is fixedly connected to the top of the electrical box housing, the connecting tooth is fixedly connected to the inner wall of the limiting ring, and the circumferential ring is fixedly connected to the outer wall of the main spring rod. The circumferential ring is connected to the top of the electrical box housing by a spring.

[0009] In one or more embodiments of the present invention, the safety limiting device further includes a square groove, a sliding tooth, and a circumferential rod. The square groove is fixedly connected to the outer circumferential surface of the circumferential ring, the sliding tooth is slidably connected to the inner wall of the square groove, the sliding tooth is connected to the outer wall of the circumferential ring by a spring, the fixed tooth is located on the movement trajectory of the sliding tooth, and the circumferential rod is fixedly connected to the outer circumferential surface of the circumferential ring.

[0010] In one or more embodiments of the present invention, the safety limiting device further includes a slot, a limiting post, an arc-shaped limiting groove, and a helical tooth surface. The slot is formed on the inner wall of the limiting ring, the limiting post is fixedly connected to the outer wall of the circumferential rod, the arc-shaped limiting groove is formed on the top of the electrical box housing, the outer wall of the limiting post is slidably connected to the inner wall of the arc-shaped limiting groove, the circumferential rod is slidably connected to the slot, and the helical tooth surface is formed on the outer wall of the fixed tooth. The helical tooth surface is located on the movement trajectory of the sliding tooth. As the cable moves, it drives the main spring rod to rotate. This rotation, in turn, causes the circumferential ring to rotate, which in turn rotates the square groove. The square groove then moves the sliding teeth, which are pressed inward by the connecting teeth. During this movement, the sliding teeth become engaged in the gaps between the connecting teeth, providing a fixed constraint on the main spring rod. This prevents cable retraction during charging, ensuring charging is not interrupted, protecting the charging nozzle and interface, and preventing safety risks from cable pulling. Once fixed in place, the cable experiences even stress, preventing damage from minor vehicle movements, wind, or uneven ground. This causes the charging cable to be under stress, making the entire charging process more stable. When charging is complete, pulling the cable drives the sliding tooth to continue rotating. After the sliding tooth rotates to the last fixed tooth, it will lose its limit due to the guidance of the helical tooth surface, causing the main spring rod to lose its limit and automatically reset. During the rotation of the circumferential ring, the circumferential rod rotates under the limit of the slot. During the rotation of the circumferential rod, the limiting post rotates under the limit of the arc-shaped limiting groove. Under the limit of the arc-shaped limiting groove, when the main spring rod rotates to the critical angle, the limiting post will be limited by the arc-shaped limiting groove, thereby stopping the main spring rod from rotating and preventing the internal torsion spring from being damaged due to excessive rotation of the main spring rod.

[0011] In one or more embodiments of the present invention, the heat dissipation protection mechanism includes a hollow frame, a maintenance leaf, a vertical rotating rod, and a vertical moving piece. The hollow frame is fixedly connected to the outer wall of the electrical box housing, the maintenance leaf is rotatably connected to the inner wall of the hollow frame, the vertical rotating rod is fixedly connected to the bottom of the main spring rod, and the vertical moving piece is movably connected to the outer circumferential surface of the vertical rotating rod.

[0012] In one or more embodiments of the present invention, the protective heat dissipation mechanism further includes a vertical plate rod, a vertical short groove, a horizontal plate, and a guide plate body. The vertical plate rod is slidably connected to the inner wall of the hollow frame, and the vertical plate rod is fixedly connected to the vertical moving plate. The vertical short groove is formed on the outer wall of the hollow frame, the horizontal plate is slidably connected to the inner wall of the vertical short groove, and the guide plate body is fixedly connected to the outer wall of the vertical plate rod.

[0013] In one or more embodiments of the present invention, the protective heat dissipation mechanism further includes a transmission gear, a drive rack, a vertical moving rod, a drive ring, and a transverse connecting frame. The transmission gear is fixedly connected to the left side of the maintenance page, the drive rack is fixedly connected to the outer wall of the vertical rod, and the transmission gear and the drive rack are meshed and connected. The vertical moving rod is fixedly connected to the top of the transmission gear and is fixedly connected to the guide plate body. The drive ring is slidably connected to the outer wall of the cable, the transverse connecting frame is fixedly connected to the outer wall of the vertical moving rod, and the drive ring is fixedly connected to the vertical moving rod. During the rotation of the circumferential ring, the vertical rotating rod at the bottom rotates as well. This rotation, through the spiral groove on the circumferential surface, drives the vertical moving plate to move. As the vertical moving plate moves, it causes the vertical plate rod to move within the confines of the hollow frame's inner wall. This movement of the vertical plate rod engages the drive rack and transmission gears, causing the transmission gears to rotate. This rotation of the transmission gears then drives the maintenance cover to rotate, unfolding it upwards. When not in use, the maintenance cover is closed to block external dust and rain, thus protecting the internal circuit board. During operation, the maintenance cover unfolds upwards to release... When the charging gun returns to its original position after charging is complete, it automatically closes, thus balancing heat dissipation and protection. As the vertical lever moves upward, it drives the guide plate to move upward, which in turn drives the horizontal connecting frame to move upward. The movement of the horizontal connecting frame drives the drive ring to move, which in turn causes the cable to sway. This causes the cable to shake off water droplets and fallen leaves when it is pulled by the drive ring. When the cable is pressed, twisted, or bent, the internal core may be stressed or have poor contact. The drive ring shakes and straightens the core, making the charging process smoother and reducing the occurrence of poor contact.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. With the cooperation of the traction rope, fixed ball, cable, and electrical box housing, the traction rope rotates during its circular motion, causing the fixed ball to rotate. As the fixed ball rotates, it lifts the cable, ensuring it remains suspended throughout the extension process. This prevents friction with the ground, crushing, and water immersion, reduces damage to the cable's insulation layer, lowers the risk of electrical leakage, and significantly extends the cable's lifespan. The movement of the traction rope also moves the fixed ball, which in turn pulls the cable closer to the electrical box housing. When the device is not in use for extended periods, the cable will be close to the outer wall of the housing, preventing it from becoming entangled and creating safety hazards.

[0015] 2. With the cooperation of the fixed teeth, sliding teeth, and main spring rod, the sliding teeth are squeezed by the fixed teeth during the movement, causing them to stretch inward. The sliding teeth are stuck in the gap between the fixed teeth during the movement, which provides a fixed constraint on the main spring rod. This prevents the cable from being retracted during the charging process of the electric vehicle, thus preventing charging interruption, protecting the safety of the charging gun and interface, and avoiding safety risks caused by cable pulling. After the cable is fixed, the cable is subjected to uniform force, and the charging gun will not be stressed due to slight vehicle movement, wind, or uneven ground, making the charging process more stable.

[0016] 3. With the cooperation of the vertical lever, drive rack, and maintenance cover, the vertical lever moves to drive the drive rack to mesh with the transmission gear, thereby causing the transmission gear to rotate. During the rotation of the transmission gear, the maintenance cover rotates and unfolds upward. When not in use, the maintenance cover is closed to block external dust and rainwater, thus protecting the circuit board inside the device. During operation, the maintenance cover unfolds upward to dissipate heat. When charging is complete, it automatically closes when the charging gun returns to its position, thus taking into account both heat dissipation and protection. Attached Figure Description

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a charging gun cable storage device based on new energy vehicles, including an electrical box housing 1, a cable 2 provided on the inner wall of the electrical box housing 1, a charging gun 3 provided on the outer wall of the electrical box housing 1, a charging gun 3 provided on the outer wall of the cable 2, a swing arm device 4 provided on the top of the electrical box housing 1, a safety limiting device 5 provided on the top of the electrical box housing 1, and a protective heat dissipation mechanism 6 provided on the inner wall of the electrical box housing 1. The swing arm device 4 includes a main spring rod 401, a C-shaped frame 402, a vertical column 403, and a horizontal torsion column 404. The main spring rod 401 is rotatably connected to the inner wall of the electrical box housing 1 via a torsion spring. The C-shaped frame 402 is fixedly connected to the top of the main spring rod 401. The vertical column 403 is fixedly connected to the inner wall of the C-shaped frame 402. The horizontal torsion column 404 is rotatably connected to the outer wall of the vertical column 403. The maximum rotation angle of the main spring rod 401 is 180 degrees. A sensor is installed at the bottom of the electrical box housing 1.

[0021] The swing arm device 4 also includes a screw rod 405 and a drive block 406. The screw rod 405 is rotatably connected to the inner wall of the transverse torsion column 404, and the drive block 406 is movably connected to the outer circumferential surface of the screw rod 405. The drive block 406 is slidably connected to the inner wall of the transverse torsion column 404, and a motor is provided on the right side of the screw rod 405.

[0022] The swing arm device 4 also includes a traction rope 407 and a fixed ball 408. The traction rope 407 is fixedly connected to the bottom of the drive block 406. The traction rope 407 is slidably connected to the inner wall of the transverse torsion column 404. The fixed ball 408 is fixedly connected to the bottom of the traction rope 407. The inner wall of the fixed ball 408 is fixedly connected to the cable 2. During the circular motion of the traction rope 407, the fixed ball 408 rotates. As the fixed ball 408 rotates and moves, it lifts the cable 2, thus suspending the cable 2 in the air throughout the pulling and extension process. This avoids friction with the ground, crushing, and water immersion, reduces damage to the insulation layer of the cable 2, lowers the risk of leakage, and significantly extends the life of the cable 2. The movement of the traction rope 407 also moves the fixed ball 408, causing the cable 2 to move closer to the electrical box housing 1. When the device is not in use for a long time, the cable 2 will be close to the outer wall of the electrical box housing 1 and coiled up close to the electrical box housing 1. This prevents the cable 2 from being scattered in the air and obstructing pedestrians and animals when not in use, and prevents the cable 2 from getting tangled in the air and causing safety hazards.

[0023] The safety limiting device 5 includes a limiting ring 501, a connecting tooth 502, and a circumferential ring 503. The limiting ring 501 is fixedly connected to the top of the electrical box housing 1, the connecting tooth 502 is fixedly connected to the inner wall of the limiting ring 501, and the circumferential ring 503 is fixedly connected to the outer wall of the main spring rod 401. The circumferential ring 503 is connected to the top of the electrical box housing 1 by a spring.

[0024] The safety limiting device 5 also includes a square groove 504, a sliding tooth 505, and a circumferential rod 506. The square groove 504 is fixedly connected to the outer circumferential surface of the circumferential ring 503. The sliding tooth 505 is slidably connected to the inner wall of the square groove 504. The sliding tooth 505 is connected to the outer wall of the circumferential ring 503 by a spring. The fixed tooth 502 is located on the movement trajectory of the sliding tooth 505. The circumferential rod 506 is fixedly connected to the outer circumferential surface of the circumferential ring 503.

[0025] The safety limiting device 5 also includes a slot 507, a limiting post 508, an arc-shaped limiting groove 509, and a helical tooth surface 510. The slot 507 is opened on the inner wall of the limiting ring 501. The limiting post 508 is fixedly connected to the outer wall of the circumferential rod 506. The arc-shaped limiting groove 509 is opened on the top of the electrical box housing 1. The outer wall of the limiting post 508 and the inner wall of the arc-shaped limiting groove 509 are slidably connected. The circumferential rod 506 and the slot 507 are slidably connected. The helical tooth surface 510 is opened on the outer wall of the fixed tooth 502. The helical tooth surface 510 is located on the movement trajectory of the sliding tooth 505. During the movement of the sliding tooth 505, it is squeezed by the fixed tooth 502, causing it to extend and retract inward. The sliding tooth 505 is stuck in the gap between the fixed teeth 502 during the movement, which provides a fixed constraint on the main spring rod 401. This prevents the cable 2 from being retracted during the charging process of the electric vehicle, thus preventing charging interruption, protecting the safety of the nozzle and interface, and avoiding safety risks caused by the cable 2 being pulled. After the cable 2 is limited and fixed, the cable 2 is subjected to uniform force, and the cable will not be subjected to force due to slight vehicle movement, wind, or uneven ground, making the charging process more stable.

[0026] Working Principle: When charging a vehicle, the device pulls the charging gun 3 to move it to the charging port of the trolley, connecting it to charge the trolley. During this pulling process, the charging gun 3 moves the cable 2, which in turn rotates the main spring rod 401. This rotation of the main spring rod 401, in turn, rotates the C-frame 402. The rotation of the C-frame 402 then rotates the vertical column 403, which in turn rotates the horizontal torsion column 404. This rotation of the horizontal torsion column 404 causes the traction rope 407 to rotate in a circular motion. This circular motion of the traction rope 407 then rotates the fixed ball 408. The rotating and moving fixed ball 408 supports the cable 2, thus suspending the cable 2 throughout its extension process. This prevents friction, crushing, and water damage to the cable 2's insulation layer, reduces the risk of leakage, and significantly extends the cable 2's lifespan. When the device is not in use, the electrical box... The sensor inside the housing 1 receives a signal, which then transmits a signal to the motor, causing the motor to start automatically. The motor starts and drives the screw rod 405 to rotate. During the rotation of the screw rod 405, the drive block 406 moves under the limit of the transverse torsion column 404 through the spiral groove on the circumferential surface. During the movement of the drive block 406, the bottom traction rope 407 moves towards the electrical box housing 1. The movement of the traction rope 407 drives the fixed ball 408 to move. The movement of the fixed ball 408 drives the cable 2 to move closer to the electrical box housing 1. When the device is not in use for a long time, the cable 2 will be close to the outer wall of the electrical box housing 1 and coiled up. This prevents the cable 2 from being scattered in the air and obstructing pedestrians and animals when not in use, and prevents the cable 2 from getting tangled in pedestrians and animals, thus reducing safety hazards and the risk of damage to the device.

[0027] During its movement, cable 2 drives the main spring rod 401 to rotate. The rotation of the main spring rod 401 causes the circumferential ring 503 to rotate, which in turn causes the square groove 504 to rotate. The rotation of the square groove 504 then moves the sliding tooth 505. As the sliding tooth 505 moves, it is squeezed by the connecting teeth 502, causing it to extend and retract inwards. The sliding tooth 505 becomes lodged in the gap between the connecting teeth 502, providing a fixed constraint on the main spring rod 401. This prevents cable 2 from retracting during charging, thus preventing charging interruption, protecting the nozzle and interface, and avoiding safety risks caused by cable 2 being pulled. After being fixed in place, cable 2 experiences uniform force, preventing stress on the cable due to slight vehicle movement, wind, or uneven ground. To ensure a more stable charging process, when charging is complete, pulling the cable 2 causes the sliding tooth 505 to continue rotating. After the sliding tooth 505 rotates to the last fixed tooth 502, it will be guided by the helical tooth surface 510 to lose its limit, causing the main spring rod 401 to lose its limit and automatically reset. During the rotation of the circumferential ring 503, the circumferential rod 506 rotates under the limit of the slot 507. During the rotation of the circumferential rod 506, the limiting post 508 rotates under the limit of the arc-shaped limiting groove 509. Under the limit of the arc-shaped limiting groove 509, when the main spring rod 401 rotates to the critical angle, the limiting post 508 will be limited by the arc-shaped limiting groove 509, thereby stopping the main spring rod 401 from rotating too much and causing damage to the internal torsion spring.

[0028] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the heat dissipation protection mechanism 6 includes a hollow frame 601, a maintenance page 602, a vertical rotating rod 603, and a vertical moving piece 604. The hollow frame 601 is fixedly connected to the outer wall of the electrical box housing 1, the maintenance page 602 is rotatably connected to the inner wall of the hollow frame 601, the vertical rotating rod 603 is fixedly connected to the bottom of the main spring rod 401, and the vertical moving piece 604 is movably connected to the outer circumferential surface of the vertical rotating rod 603.

[0029] The heat dissipation protection mechanism 6 also includes a vertical bar 605, a vertical short groove 606, a horizontal plate 607, and a guide plate body 608. The vertical bar 605 is slidably connected to the inner wall of the hollow frame 601, and the vertical bar 605 is fixedly connected to the vertical moving plate 604. The vertical short groove 606 is opened on the outer wall of the hollow frame 601. The horizontal plate 607 is slidably connected to the inner wall of the vertical short groove 606, and the guide plate body 608 is fixedly connected to the outer wall of the vertical bar 605.

[0030] The heat dissipation protection mechanism 6 also includes a transmission gear 609, a drive rack 610, a vertical rod 611, a drive ring 612, and a transverse connecting frame 613. The transmission gear 609 is fixedly connected to the left side of the maintenance page 602. The drive rack 610 is fixedly connected to the outer wall of the vertical rod 605. The transmission gear 609 and the drive rack 610 are meshed and connected. The vertical rod 611 is fixedly connected to the top of the transmission gear 609. The vertical rod 611 is fixedly connected to the guide plate body 608. The drive ring 612 is slidably connected to the outer wall of the cable 2. The transverse connecting frame 613 is fixedly connected to the outer wall of the vertical rod 611. The drive ring 612 is fixedly connected to the vertical rod 611. The vertical lever 605 moves, causing the drive rack 610 to mesh with the transmission gear 609, thereby causing the transmission gear 609 to rotate. During the rotation of the transmission gear 609, the maintenance page 602 rotates and unfolds upward. When not in use, the maintenance page 602 is closed to block external dust and rainwater, thus protecting the circuit board inside the device. During operation, the maintenance page 602 unfolds upward to dissipate heat. When charging is complete, the charging gun 3 returns to its original position and automatically closes, thus taking into account both heat dissipation and protection.

[0031] Working principle: During the rotation of the circumferential ring 503, the vertical rotating rod 603 at the bottom rotates. The rotation of the vertical rotating rod 603 drives the vertical moving plate 604 to move through the spiral groove on the circumferential surface. During the movement of the vertical moving plate 604, the vertical plate rod 605 moves under the limit of the inner wall of the hollow frame 601. The movement of the vertical plate rod 605 drives the drive rack 610 to mesh with the transmission gear 609, thereby causing the transmission gear 609 to rotate. During the rotation of the transmission gear 609, the maintenance page 602 rotates and unfolds upwards. The maintenance page 602 is closed when not in use, blocking external dust and rainwater, thus protecting the internal circuit board of the device. During operation... The maintenance page 602 unfolds upwards for heat dissipation. When charging is complete, the charging gun 3 returns to its position and automatically closes, thus balancing heat dissipation and protection. As the vertical lever 605 moves upwards, it drives the guide plate body 608 to move upwards. The upward movement of the guide plate body 608 drives the horizontal connecting frame 613 to move upwards. The movement of the horizontal connecting frame 613 drives the drive ring 612 to move. The movement of the drive ring 612 causes the cable 2 to shake. As the cable 2 is pulled, it shakes under the drive of the drive ring 612, shaking off the water droplets and fallen leaves adhering to it. When the cable 2 is pressed, twisted, or bent, the internal core may be stressed or have poor contact. After the drive ring 612 shakes and straightens it, the charging process is smoother and the occurrence of poor contact is reduced.
