Description

Technical Field

[0001] This invention relates to an intelligent charging pile with intelligent charging cable retraction and extension, belonging to the field of charging pile technology. Background Technology

[0002] Charging piles are specialized supporting equipment that provides charging for new energy electric vehicles and hybrid vehicles. With the rapid development of the new energy vehicle industry, charging pile equipment has been widely adopted. Existing conventional charging piles mainly consist of a lifting module, a control module, charging cables, and a charging gun. The control module is mounted on the upper part of the lifting module, and the charging cables are electrically connected to the control module and the charging gun, respectively.

[0003] To accommodate the charging needs of vehicles in different parking locations, charging cables are usually designed with an extended structure. This structural feature makes the cables prone to becoming tangled and sluggish when not in use, and long-term exposure can cause wear and tear, shortening their lifespan.

[0004] Currently, the industry generally uses external hook structures to store charging cables. When the equipment is not in use, the cables are manually hung neatly on the hooks. However, this purely manual storage method has significant technical defects and safety hazards: First, after the charging operation is completed, the staff may forget to store the cables, causing them to be scattered on the ground for a long time, which makes them very easy to be crushed or stepped on, greatly increasing the probability of cable damage. Second, if the stored cables are not retrieved before the charging operation, the effective charging length will be insufficient, resulting in problems such as improper insertion of the charging gun and poor contact. This not only aggravates cable wear but also seriously affects the charging stability and charging quality, posing charging failures and electrical safety hazards. Summary of the Invention

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Example 1: As Figures 1-4 As shown, a smart charging pile with intelligent charging cable retraction is provided, including: a main body 1, a charging gun 2 inserted into the right end of the main body 1, the charging gun 2 being used to connect with the vehicle to be charged, a housing 5 set in the middle of the lower end of the main body 1, the housing 5 providing a mounting carrier for components such as the retracting rod 6, a hollow lifting rod 4 installed on the lower end of the housing 5, the lifting rod 4 providing a mounting carrier for the housing 5 on the one hand, and a hidden space for the drive equipment on the other hand, and a base 41 set on the lower end of the lifting rod 4, the base 41 providing a mounting carrier for the lifting rod 4; The winding rod 6 is rotatably connected to the top of the inside of the outer shell 5. The charging cable 3 is wound up by the winding rod 6. A through groove 51 is formed by the right end of the outer shell 5 facing left, and the through groove 51 extends to the inner wall of the outer shell 5. The wound charging cable 3 is led out of the outer shell 5 through the through groove 51. The charging cable 3 is wound on the winding rod 6, and the movable end of the charging cable 3 passes through the through groove 51 and is connected to the charging gun 2. The conductive rod 61 is installed inside the winding rod 6, and the upper end of the conductive rod 61 passes through the winding rod 6 and the outer shell 5 and is rotatably electrically connected to the main body 1. The fixed end of the charging cable 3 passes through the winding rod 6 and is electrically connected to the conductive rod 61. The charging cable 3 is connected to the main body 1 through the conductive rod 61. The fixed part of the drive device located inside the lifting rod 4 is installed on the lower end of the outer shell 5, and the output shaft of the drive device passes through the outer shell 5 and is connected to the winding rod 6. The drive device is electrically connected to the main body 1. The drive device drives the winding rod 6 to rotate. The drive device can be a motor 7 with a reducer. Multiple heat dissipation vents are evenly opened on the outer end face of the lifting rod 4, and the heat dissipation vents are located on the outside of the driving device. The multiple heat dissipation vents work together to dissipate heat from the driving device. Dustproof nets are installed in the multiple heat dissipation vents to achieve dust prevention. The protective box 11 is installed on the right end of the main body 1, and the card seat on the main body 1 is located inside the protective box 11. The protective box 11 protects the card seat on the one hand, and provides installation space for the sensor 111 on the other hand. A recessed insertion hole is formed on the right side of the protective box 11, extending to the inner wall of the protective box 11. The end of the charging gun 2 facing away from the charging cable 3 is inserted into the right end of the insertion hole. The charging gun 2 passes through the insertion hole and is inserted into the card holder of the main body 1. The charging gun 2 can be normally placed and removed through the insertion hole. The sensor 111 located directly above the charging gun 2 is installed at the top inside the protective box 11 and is electrically connected to the main body 1. The sensor 111 senses whether the charging gun 2 is placed. A detector is embedded in the front end of the main body 1. The detector collects information such as the distance of the vehicle to be charged.

[0019] When in use, the detector first collects information such as the distance to the stationary vehicle to be charged and sends the vehicle information to the main body 1. The driver moves out of the vehicle to be charged and holds the charging gun 2. Then the charging gun 2 is taken out of the protective box 11. At this time, the sensor 111 cannot detect the charging gun 2 and sends sensing information to the main body 1. The main body 1 analyzes and calculates the received vehicle information and sensing information, and then sends out the corresponding control signal. The motor 7 receives the control signal and starts. The operation of the motor 7 will drive the winding rod 6 to rotate and extend the wound charging cable 3. At this time, the driver can hold the charging gun 2 and move it towards the vehicle to be charged. Then the driver inserts the holding charging gun 2 into the charging port of the vehicle to be charged. At this time, the motor 7 rotates the corresponding number of turns according to the control signal, thereby controlling the extension length of the charging cable 3. Then the main body 1 charges the vehicle through the conductive rod 61, the charging cable 3 and the charging gun 2. After charging is complete, remove the charging gun 2 from the vehicle and re-insert it through the socket on the protective box 11 and engage it with the card slot on the main body 1. At this time, the sensor 111 senses the charging gun 2 and sends sensing information to the main body 1. The main body 1 analyzes and calculates the received vehicle information and sensing information, and then sends out the corresponding control signal. The motor 7 receives the control signal and starts. The motor 7 receives the control signal and starts. The operation of the motor 7 will drive the winding rod 6 to rotate in the opposite direction and rewind the extended length of the charging cable 3. This realizes the winding and unwinding of the charging cable 3 and makes the winding and unwinding operation intelligent, effectively reducing the probability of damage to the charging cable 3, improving safety, and effectively ensuring the charging effect and quality.

[0020] Example 2: Figures 2-8 As shown, a spiral groove 62 is formed by an inward recess at the annular end of the take-up rod 6, and the charging cable 3 is wound inside the spiral groove 62. The take-up rod 6 and the spiral groove 62 work together to organize the charging cable 3 in an orderly manner. A first synchronous pulley 63 is set at the middle of the lower end of the take-up rod 6. The output shaft of the drive device passes through the housing 5 and the first synchronous pulley 63 and is connected to the take-up rod 6. The output shaft of the drive device is fixedly connected to the first synchronous pulley 63. The corresponding synchronous belt rotates using the first synchronous pulley 63, and the lead screw 85 is rotated inside the housing 5. The nut seat 86 moves up and down through the lead screw 85. The second synchronous pulley 851 is installed on the lower annular end of the lead screw 85, and the second synchronous pulley 851 is connected to the first synchronous pulley 63 through a synchronous belt. The lead screw 85 rotates through the second synchronous pulley 851. The nut seat 86 located on the upper side of the second synchronous pulley 851 is connected to the annular end of the lead screw 85 through a ball nut pair. The hollow guide block 8 moves up and down through the nut seat 86. A slide rod 82 is installed inside the outer shell 5, and the annular end of the slide rod 82 is slidably connected to the slider 83. The slider 83 extending from the upper side of the hollow guide block 8 is installed on the rear end of the hollow guide block 8. The slide rod 82 and the slider 83 work together to guide the up and down movement of the hollow guide block 8. The hollow guide block 8 located on the right side of the winding rod 6 is installed on the rear end of the nut seat 86. The first guide cylinder 81, which extends into the through groove 51 at its right end, is connected to the right end of the hollow guide block 8 and is slidably connected to the through groove 51. The cross-section of the first guide cylinder 81 is a trumpet shape with a narrow left and wide right arrangement. The second guide cylinder 89 located on the right end of the winding rod 6 is connected to the left end of the hollow guide block 8 and has a trumpet shape with a wide left and narrow right arrangement. The movable end of the charging cable 3 passes through the second guide cylinder 89, the hollow guide block 8, the first guide cylinder 81, and the through groove 51 in sequence and is connected to the charging gun 2. The hollow guide block 8, the first guide cylinder 81, and the second guide cylinder 89 work together to guide the winding and unwinding movement of the charging cable 3. An installation box 84 is connected to the upper end of the hollow guide block 8. The installation box 84 provides installation space for the extrusion wheel 871. The extrusion wheel 871 is rotatably connected inside the installation box 84. The lower end of the extrusion wheel 871 passes through the installation box 84 and the hollow guide block 8 and is squeezed and attached to the upper end of the charging cable 3. The extrusion wheel 871 is used to assist in the retraction and extension of the charging cable 3. The extrusion wheel 871 is made of rubber. The rotating shaft 87 is rotatably connected to the rear end of the installation box 84. The front end of the rotating shaft 87 passes through the installation box 84 and is connected to the extrusion wheel 871. The extrusion wheel 871 is rotated through the rotating shaft 87. The auxiliary box 88 is rotatably connected to the rear end of the rotating shaft 87, and the auxiliary box 88 is connected to the left end of the slider 83. The auxiliary box 88 provides installation space for the gear 872. The left end of the slider 83 is flat, and a toothed plate 821 is installed on the left end of the flat surface. The toothed plate 821 passes through the slider 83, and the gear 872 is rotated through the toothed plate 821. The gear 872 is rotatably connected inside the auxiliary box 88, and the right end of the gear 872 passes through the auxiliary box 88 and the slider 83 and meshes with the left end of the toothed plate 821. The rear end of the rotating shaft 87 passes through the auxiliary box 88 and is connected to the gear 872. The rotating shaft 87 is rotated through the gear 872.

[0021] During the winding and unwinding of the charging cable 3, the operation of the motor 7 causes the first synchronous pulley 63 to rotate, and with the assistance of the synchronous belt, the second synchronous pulley 851 rotates, which in turn causes the lead screw 85 to rotate accordingly. Since the lead screw 85 is connected to the nut seat 86 through a ball nut pair, the rotation of the lead screw 85 causes the nut seat 86 to move up and down, which in turn causes the hollow guide block 8, the first guide cylinder 81, and the second guide cylinder 89 to move up and down, thereby achieving orderly guidance of the winding and unwinding of the charging cable 3. The spiral groove 62 is used to effectively store and release the charging cable 3, effectively reducing the probability of knots or other phenomena occurring during the winding and unwinding process. The guiding movement and winding and unwinding of the charging cable 3 are linked, effectively ensuring the charging effect and quality. During the up-and-down movement of the hollow guide block 8, the slider 83 will move up and down along the slide bar 82. At this time, the sliding motion between the slider 83 and the slide bar 82 will guide the movement of the hollow guide block 8. The up-and-down movement of the slider 83 will cause the auxiliary box 88 to move up and down, which will cause the gear 872 and the toothed plate 821 to move relative to each other. Since the gear 872 and the toothed plate 821 mesh with each other, the relative movement of the gear 872 and the toothed plate 821 will cause the gear 872 to rotate in the corresponding direction. The rotation of gear 872 causes the shaft 87 to rotate, which in turn causes the extrusion wheel 871 to rotate. Since the lower end of the extrusion wheel 871 is in a pressing fit with the charging cable 3, the rotation of the extrusion wheel 871 will apply a pushing force to the charging cable 3, thereby assisting in the winding and unwinding of the charging cable 3. This effectively reduces the probability of cable jamming during the winding and unwinding process, and achieves a linkage between the auxiliary pushing motion, guiding motion, and winding and unwinding of the charging cable 3, effectively ensuring the charging effect and quality.
