Description

Technical Field

[0001] This invention relates to the field of charging piles, specifically to a charging pile. Background Technology

[0002] New energy charging piles are devices that provide power to electric vehicles. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They charge various models of electric vehicles according to different voltage levels. The input end of the new energy charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Their widespread application is of great significance for promoting green transportation and reducing environmental pollution. With the popularization of new energy vehicles, the construction and development of charging piles has become an indispensable part of the new energy vehicle industry.

[0003] Charging piles mainly consist of a charging pile chassis, a charging gun, and charging cables. The charging gun and connected cables are constantly exposed to the outside environment, making them prone to tangling and damage. Existing Chinese patent document CN114683898B discloses a new energy vehicle charging pile. By adjusting the positions of supporting pulleys and two supporting plates, it ensures that the charging cable remains taut on the outside of the supporting pulleys when stretched. This ensures the charging cable is always taut on the outside of the supporting pulleys and is neatly and orderly stored, preventing tangling during use and storage. However, while this method effectively stores the cable, the rubber surface can cause tension, potentially leading to cracks or breakage. Furthermore, pulling the cable while maintaining a stretched state, improper force, can cause elastic extension of the cable surface, further increasing the risk of cable sheath breakage. Summary of the Invention

[0004] The purpose of this invention is to provide a charging station that allows the cable to be stored in a spiral shape, and pulls the charging plug to pull the cable out of the mounting frame in a rotating manner, thereby improving the convenience of taking out the charging plug, solving the problem of the cable being too taut, and improving the durability of the cable.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A charging pile includes: a charging pile housing and two symmetrically arranged mounting cavities on both sides of the charging pile housing. A mounting frame is slidably mounted inside each mounting cavity. A cable is arranged inside the mounting frame, and a charging plug is fixedly mounted at one end of the cable for connecting and charging a new energy vehicle. Four electrically operated telescopic rods arranged in a rectangular array are fixedly mounted between the mounting cavity and the mounting frame for extending and retracting the mounting frame. The pile also includes: a winding mechanism for improving the ease of cable retrieval, the winding mechanism being installed inside the mounting frame; a cable winding mechanism for recycling and storing the cable, the cable winding mechanism being installed inside the mounting frame; and a wire guide mechanism for retrieving and positioning the charging plug, the wire guide mechanism being installed outside the charging plug.

[0007] Preferably, the winding mechanism includes two U-shaped frames symmetrically fixedly installed on the inner top and bottom sides of the mounting frame, respectively. Two symmetrically distributed circular boxes are fixedly installed between the two U-shaped frames. A cable take-up box is fixedly installed between the two circular boxes. The cable take-up box has a hollow disc structure. A positioning shaft is rotatably installed on the inner side of the cable take-up box. The cable is fixedly installed on the outer side of the positioning shaft and distributed in a spiral shape inside the cable take-up box for easy and quick cable take-up. The end of the cable away from the charging plug passes through one end of the cable take-up box. The cable is connected to the charging pile chassis. Pulling the cable can drive the positioning shaft to rotate and pull out the cable. The outer side of the cable retractor has an opening for pulling out the cable. One end of the positioning shaft is fixedly installed with a coil spring to facilitate cable reset and retraction. The end of the coil spring away from the positioning shaft is fixedly connected to the inner side of the circular box. The end of the positioning shaft away from the coil spring is fixedly installed with a ratchet. The inner side of the circular box is provided with two arc-shaped teeth that are centrally symmetrically distributed and cooperate with the ratchet, so that the ratchet rotates in one direction and prevents the coil spring from rebounding and pulling the cable.

[0008] Preferably, the take-up mechanism includes a fixed plate fixedly installed on the outside of the arc-shaped locking teeth, a positioning plate provided on the outside of the fixed plate, the positioning plate fixedly installed on the inside of the take-up box, a support rod slidably passing through the positioning plate fixedly installed on the top of the fixed plate, a positioning spring fixedly installed between the positioning plate and the fixed plate, so that when the ratchet rotates, it can push the arc-shaped locking teeth to retract the positioning spring and reset it to push the arc-shaped locking teeth into the next tooth groove of the ratchet. A prismatic sliding rod is fixedly installed at the end of the support rod away from the fixed plate. The surfaces of the U-shaped frame and the mounting frame are both provided with openings for... The sliding hole for limiting the sliding of the rhomboid slide rod is described above. A stop rod is slidably installed on the inner side of the U-shaped frame. One end of the stop rod is fixedly installed on the inner side of the mounting cavity. A through hole is opened on the outer side of the rhomboid slide rod for limiting the sliding of the stop rod. The height of the through hole is greater than the height of the stop rod, so that the through hole of the rhomboid slide rod can move upward along the outer side of the stop rod. A push block is fixedly installed on the top of the through hole. The side of the push block near the stop rod is a sloping structure, and the end of the stop rod near the rhomboid slide rod is an arc-shaped structure, so that when the stop rod contacts the sloping surface of the push block, it can drive the rhomboid slide rod to move upward through the push block.

[0009] Preferably, the cable mechanism includes an arc-shaped plate disposed above the charging plug to facilitate contact with the top of the charging plug. An arc-shaped strip is fixedly installed on the inner side of the arc-shaped plate. A mounting ring is fixedly installed at the end of the charging plug near the cable. The outer diameter of the mounting ring is smaller than the outer diameter of the charging plug. The side of the arc-shaped strip away from the arc-shaped plate is close to the outer side of the mounting ring, so that the arc-shaped strip provides a limit for the retraction of the charging plug. The outer side of the arc-shaped strip contacts the outer side of the charging plug. Fixing rods are fixedly installed at both ends of the arc-shaped plate. A support plate is fixedly installed at the end of the rod away from the arc-shaped plate. The end of the support plate away from the fixed rod is rotatably installed on the outside of the adjacent U-shaped frame. A collar is fixedly installed on the outside of the fixed rod. An arc-shaped rod is fixedly installed at the bottom of the collar. A slider is fixedly installed at the end of the arc-shaped rod away from the collar. An arc-shaped cavity is opened on the outside of the U-shaped frame for the slider to slide in a limited position. An arc-shaped spring is fixedly installed between the inside of the arc-shaped cavity and the slider, so that the arc-shaped spring can pull the slider to move the arc-shaped rod, making it easier for the arc-shaped plate and arc-shaped strip to attach to the outside of the charging plug.

[0010] Preferably, a rubber cover is fixedly installed on the outer side of the mounting frame, and a frame-shaped groove is provided on the outer side of the mounting cavity for the rubber cover to be inserted and positioned, thereby providing a seal between the mounting frame and the mounting cavity.

[0011] Preferably, the outer side of the mounting frame is provided with a material retrieval slot that is on the same vertical line as the charging plug, and the inner side of the material retrieval slot is rounded to improve the safety of picking up the charging plug.

[0012] Preferably, the end of the abutment near the prismatic slide bar and the push block are made of magnets with opposite poles, which facilitates contact between the abutment and the push block.

[0013] Preferably, a plurality of equally spaced sliding beads are slidably mounted on the inner side of the arc-shaped strip near the mounting ring, and the outer side of the sliding beads is in contact with the outer side of the mounting ring, so as to facilitate pulling the cable out along the sliding beads.

[0014] Preferably, both the arc-shaped strip and the outer side of the mounting ring are made of rubber for vibration damping and positioning.

[0015] Preferably, a roller shaft located below the arc-shaped plate is rotatably mounted at the opening of the circular box, and a concave pulley is rotatably mounted on the outer side of the roller shaft. The outer side of the concave pulley contacts the outer side of the cable, providing support for the bottom of the cable and facilitating the pulling out and retraction of the cable.

[0016] The beneficial effects that can be achieved by the above embodiments of the present invention include:

[0017] 1. This invention uses a winding mechanism to coil the cable into a spiral shape for storage. Pulling the charging plug causes the cable to rotate and be pulled out of the mounting frame, improving the convenience of taking out the charging plug, solving the problem of the cable being too taut, and improving the durability of the cable. Furthermore, the electric telescopic rod and mounting frame can store and protect the cable and charging plug, thus achieving the effect of stable cable retrieval and safe storage.

[0018] 2. The present invention, through the cable retraction mechanism, enables the cable to be taken out in only one direction when the mounting frame is far from the mounting cavity, preventing the spring from pulling the charging plug back and maintaining the connection between the charging plug and the charging port of the new energy vehicle. When the cable is retracted, the spring is unlocked, thereby achieving the effect of facilitating cable recycling.

[0019] 3. The present invention uses a wire mechanism to position and buffer the charging plug during cable recycling, preventing collisions between the charging plug and the cable reel, improving the durability of the charging plug, and preventing the charging plug from tilting during recycling, thereby facilitating the recycling and retrieval of the charging plug.

[0029] 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.

[0030] Example 1: Please refer to Figures 1-8 The diagram shows a charging pile, including a charging pile housing 1 and two symmetrically arranged mounting cavities 2 on both sides of the housing 1. A mounting frame 3 is slidably mounted inside the mounting cavity 2, and a cable 4 is arranged inside the mounting frame 3. A charging plug 5 is fixedly mounted at one end of the cable 4 for connecting and charging new energy vehicles. Four electric telescopic rods 6 arranged in a rectangular array are fixedly installed between the mounting cavity 2 and the mounting frame 3 for extending and retracting the mounting frame 3. The charging pile also includes: a winding mechanism for improving the ease of handling the cable 4, installed inside the mounting frame 3; a cable winding mechanism for recycling and storing the cable 4, installed inside the mounting frame 3; and a wire guide mechanism for retrieving and positioning the charging plug 5, installed outside the charging plug 5.

[0031] The winding mechanism includes two symmetrically fixed U-shaped frames 7, one on the top inner side and the other on the bottom inner side of the mounting frame 3. Two symmetrically distributed circular boxes 8 are fixedly installed between the two U-shaped frames 7. A cable take-up box 9 is fixedly installed between the two circular boxes 8. The cable take-up box 9 has a hollow disc structure. A positioning shaft 10 is rotatably mounted on the inner side of the cable take-up box 9. The cable 4 is fixedly installed on the outer side of the positioning shaft 10 and arranged in a spiral pattern inside the cable take-up box 9 for quick cable take-up. The end of the cable 4 away from the charging plug 5 passes through one end of the cable take-up box 9 and is aligned with the charging pile chassis 1. Pulling the cable 4 will cause the positioning shaft 10 to rotate, pulling out the cable 4. The outer side of the cable reel box 9 has an opening for pulling out the cable 4. One end of the positioning shaft 10 is fixedly installed with a coil spring 11 to facilitate the retraction of the cable 4. The end of the coil spring 11 away from the positioning shaft 10 is fixedly connected to the inner side of the circular box 8. The end of the positioning shaft 10 away from the coil spring 11 is fixedly installed with a ratchet 12. The inner side of the circular box 8 is provided with two arc-shaped teeth 13 that are centrally symmetrically distributed and cooperate with the ratchet 12, so that the ratchet 12 rotates in one direction and prevents the coil spring 11 from rebounding and pulling the cable 4.

[0032] The electric telescopic rod 6 can push the mounting frame 3 out of the mounting cavity 2 of the charging pile box 1. The user pulls the charging plug 5, which moves the cable 4, causing the cable 4 to rotate the positioning shaft 10. The wound cable 4 can be pulled out from the cable take-up box 9. The positioning shaft 10 retracts the coil spring 11 and drives the ratchet 12 to rotate. By using the cooperation of the ratchet 12 and the arc-shaped locking teeth 13, the positioning shaft 10 can only rotate in one direction, preventing the coil spring 11 from causing the positioning shaft 10 to spring back and pull. This facilitates the connection between the charging plug 5 and the charging port of the new energy vehicle, solves the problem of the cable 4 being too taut, improves the durability of the cable 4, and thus achieves the effect of smooth cable take-up and safe storage.

[0033] The take-up mechanism includes a fixed plate 14 fixedly mounted on the outside of the arc-shaped locking tooth 13. A positioning plate 15 is provided on the outside of the fixed plate 14. The positioning plate 15 is fixedly mounted on the inside of the take-up box 9. A support rod 16 is fixedly mounted on the top of the fixed plate 14, sliding through the positioning plate 15. A positioning spring 17 is fixedly mounted between the positioning plate 15 and the fixed plate 14, so that when the ratchet 12 rotates, it can push the arc-shaped locking tooth 13 to retract the positioning spring 17 and reset it to push the arc-shaped locking tooth 13 into the next tooth groove of the ratchet 12. A prismatic sliding rod 18 is fixedly mounted on the end of the support rod 16 away from the fixed plate 14. The surfaces of the U-shaped frame 7 and the mounting frame 3 are both provided with openings for... The sliding hole of the rhomboid slide rod 18 limits its sliding. A stop rod 19 is slidably installed on the inner side of the U-shaped frame 7. One end of the stop rod 19 is fixedly installed on the inner side of the mounting cavity 2. A through hole is opened on the outer side of the rhomboid slide rod 18 for the stop rod 19 to limit its sliding. The height of the through hole is greater than the height of the stop rod 19, so that the through hole of the rhomboid slide rod 18 can move upward along the outer side of the stop rod 19. A push block 20 is fixedly installed on the top of the through hole. The side of the push block 20 near the stop rod 19 is a sloping structure, and the end of the stop rod 19 near the rhomboid slide rod 18 is an arc-shaped structure, so that when the stop rod 19 contacts the sloping surface of the push block 20, it can drive the rhomboid slide rod 18 to move upward through the push block 20.

[0034] When the ratchet 12 rotates, it pushes the arc-shaped locking tooth 13 to move, causing the arc-shaped locking tooth 13 to push the support rod 16 along the inner side of the positioning plate 15 through the fixing plate 14, compressing the positioning spring 17. When the ratchet 12 stops rotating, the rebound force of the positioning spring 17 facilitates the arc-shaped locking tooth 13 to limit the ratchet 12 again, maintaining the limit on the cable 4. When the electric telescopic rod 6 pulls the mounting frame 3 to reset, the arc-shaped end of the abutment 19 contacts the inclined surface of the push block 20, causing the abutment 19 to push the push block 20 to move. The push block 20 drives the prismatic slide rod 18 to move synchronously, causing the prismatic slide rod 18 to pull the support rod 16 to move. The support rod 16 pulls the arc-shaped locking tooth 13 away from the ratchet 12 through the fixing plate 14, thus unlocking the ratchet 12. The retracted coil spring 11 can then drive the positioning shaft 10 to rotate, retrieving the cable 4, thereby achieving the effect of facilitating the retrieval of the cable 4 and improving the convenience of cable 4 retrieval.

[0035] Working principle: First, the user starts the electric telescopic rod 6 through the control panel of the charging pile housing 1. The electric telescopic rod 6 pushes the mounting frame 3 to move, causing the mounting frame 3 to move out of the mounting cavity 2 of the charging pile housing 1. Then, the user holds the charging plug 5 and pulls it outward. The charging plug 5 drives the cable 4 to move. The cable 4 drives the positioning shaft 10 to rotate, causing the wound cable 4 to be pulled out of the take-up box 9. The positioning shaft 10 retracts the coil spring 11. At the same time, the positioning shaft 10 drives the ratchet 12 to rotate, and the ratchet 12 pushes... The arc-shaped locking tooth 13 moves, causing it to push the support rod 16 along the inner side of the positioning plate 15 via the fixing plate 14, compressing the positioning spring 17. When the cable 4 is pulled to the appropriate length, the cable 4 stops moving. The rebound force of the positioning spring 17 causes the arc-shaped locking tooth 13 to insert into the tooth groove of the ratchet 12, preventing the coil spring 11 from pulling back the positioning shaft 10. This facilitates the connection of the charging plug 5 with the charging port of the new energy vehicle, solves the problem of the cable 4 being too taut, and improves the durability of the cable 4. Users can pull out the cable 4 of the corresponding length as needed. After the new energy vehicle is charged, the electric telescopic rod 6 pulls the mounting frame 3 back into the mounting cavity 2. During the movement of the mounting frame 3, the arc-shaped end of the abutment rod 19 contacts the inclined surface of the push block 20, causing the abutment rod 19 to push the push block 20 to move. At the same time, the electric telescopic rod 6 stops running, and the push block 20 drives the prismatic slide rod 18 to move synchronously, causing the prismatic slide rod 18 to pull the support rod 16 to move. The support rod 16 pulls the arc-shaped locking teeth 13 through the fixing plate 14. Synchronous movement causes the arc-shaped locking teeth 13 to be pulled out of the tooth grooves of the ratchet 12. As a result, the coiled spring 11 in its retracted state can drive the positioning shaft 10 to rotate, causing the positioning shaft 10 to drive the cable 4 to rotate back, thus realizing the retrieval of the cable 4. Finally, the electric telescopic rod 6 operates again, pulling the mounting frame 3 completely back into the mounting cavity 2 to store the cable 4 and the charging plug 5. This achieves the effect of stable cable retrieval and storage, and provides protective storage for the charging plug 5 and the cable 4, improving the safety of the charging plug 5 and the cable 4.

[0036] Example 2: Please refer to Figure 3 , Figure 7 and Figure 8This embodiment further explains Example 1. The wire mechanism shown in the figure includes an arc-shaped plate 21 disposed above the charging plug 5, facilitating contact with the top of the charging plug 5. An arc-shaped strip 22 is fixedly installed on the inner side of the arc-shaped plate 21. An installation ring 23 is fixedly installed on the end of the charging plug 5 near the cable 4. The outer diameter of the installation ring 23 is smaller than the outer diameter of the charging plug 5. The side of the arc-shaped strip 22 away from the arc-shaped plate 21 is close to the outer side of the installation ring 23, so that the arc-shaped strip 22 provides a limit for the retraction of the charging plug 5. The outer side of the arc-shaped strip 22 is in contact with the outer side of the charging plug 5. Fixing rods 24 are fixedly installed at both ends of the arc-shaped plate 21. A support plate 25 is fixedly installed at the end of the fixed rod 24 away from the arc plate 21. The end of the support plate 25 away from the fixed rod 24 is rotatably installed on the outside of the adjacent U-shaped frame 7. A collar 26 is fixedly installed on the outside of the fixed rod 24. An arc rod 27 is fixedly installed at the bottom of the collar 26. A slider 28 is fixedly installed at the end of the arc rod 27 away from the collar 26. An arc cavity for limiting the sliding of the slider 28 is opened on the outside of the U-shaped frame 7. An arc spring 29 is fixedly installed between the inner side of the arc cavity and the slider 28, so that the arc spring 29 can pull the slider 28 to move the arc rod 27, making it easier for the arc plate 21 and the arc strip 22 to be attached to the outside of the charging plug 5.

[0037] In this embodiment: when the cable 4 is retracted, the rebound force of the arc spring 29 can pull the slider 28 to move along the arc cavity of the U-shaped frame 7, so that the slider 28 pulls the support plate 25 and the fixed rod 24 downward through the arc rod 27. The fixed rod 24 pulls the arc strip 22 on the arc plate 21 to adhere to the outside of the cable 4, keeping the cable 4 retracted along the inside of the cable take-up box 9, preventing the cable 4 from getting tangled. When the mounting ring 23 on the charging plug 5 comes into contact with the arc strip 22, the arc strip 22 can abut against the outside of the mounting ring 23 and the charging plug 5, and the arc plate 21 abuts against the top of the charging plug 5 to position the charging plug 5. The elasticity of the arc spring 29 provides a buffer for the charging plug 5, preventing the charging plug 5 from colliding with the cable take-up box 9, improving the durability of the charging plug 5, and preventing the charging plug 5 from tilting during retraction, thereby achieving the effect of facilitating the retraction and retrieval of the charging plug 5.

[0038] Example 3: Please refer to Figure 2 and Figure 4This embodiment further illustrates other embodiments. A rubber cover 30 is fixedly installed on the outer side of the mounting frame 3 in the figure. A frame-shaped groove is opened on the outer side of the mounting cavity 2 for the rubber cover 30 to be inserted and positioned, providing a seal between the mounting frame 3 and the mounting cavity 2. A material retrieval slot 34 is opened on the outer side of the mounting frame 3, which is on the same vertical line as the charging plug 5. The inner side of the material retrieval slot 34 is rounded to improve the safety of picking up the charging plug 5. The end of the abutment 19 near the rhomboid slide rod 18 and the push block 20 are made of magnets with opposite poles, which facilitates the contact between the abutment 19 and the push block 20.

[0039] In this embodiment: when the electric telescopic rod 6 pulls the mounting frame 3 into the mounting cavity 2, the rubber cover 30 can be inserted into the frame-shaped groove on the outside of the mounting cavity 2, improving the sealing between the mounting frame 3 and the mounting cavity 2, preventing external moisture from entering, facilitating the sealing of the charging plug 5, allowing the user to take the charging plug 5 through the material retrieval slot 34, and the cable 4 can enter the inside of the material retrieval slot 34 and be bent upwards, suitable for new energy vehicles of different heights, preventing friction between the cable 4 and the mounting frame 3, when the abutment rod 19 and the push block 20 are close together, the magnetic material abutment rod 19 and push block 20 can facilitate accurate docking of the abutment rod 19 and the push block 20.

[0040] Example 4: Please refer to Figure 8 This embodiment further illustrates other embodiments. In the figure, multiple equally spaced ball bearings 31 are slidably mounted on the inner side of the arc-shaped strip 22 near the mounting ring 23. The outer side of the ball bearings 31 contacts the outer side of the mounting ring 23, making it easy to pull the cable 4 out along the ball bearings 31. The outer sides of both the arc-shaped strip 22 and the mounting ring 23 are made of rubber for vibration damping and positioning. A roller shaft 32 located below the arc-shaped plate 21 is rotatably mounted at the opening of the circular box 8. A concave pulley 33 is rotatably mounted on the outer side of the roller shaft 32. The outer side of the concave pulley 33 contacts the outer side of the cable 4, providing support for the bottom of the cable 4, making it easy to pull out and retract the cable 4.

[0041] In this embodiment: when the cable 4 is retracted, the cable 4 can move along the outside of the ball bearing 31, improving the smoothness of the cable 4 retraction. Furthermore, the arc-shaped strip 22 of the rubber structure can provide a buffer for the collision between the mounting ring 23 and the arc-shaped strip 22 when it comes into contact with the mounting ring 23. When the cable 4 is pulled out and retracted, it can move along the concave pulley 33 on the outside of the roller 32, improving the convenience of pulling out the cable 4.
