Description

Technical Field

[0001] This invention relates to the field of new energy charging pile technology, and in particular to a charging pile with automatic cable retraction. Background Technology

[0002] New energy charging piles are specialized equipment that provides power replenishment for electric vehicles and are a key infrastructure connecting energy and transportation in the new energy vehicle industry chain.

[0003] In existing technologies, charging piles do not have the function of cable storage. Scattered cables will occupy the ground space of the charging area and are easily crushed or stepped on when vehicles enter or exit or people walk by, causing cable damage or people to trip. Especially in high-frequency use scenarios such as public charging stations, messy cables will also hinder vehicle parking and charging operations, reducing charging efficiency.

[0004] Therefore, it is necessary to design an automatic charging station with retractable charging cable to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic charging station with retractable charging cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic charging station with retractable charging cable includes a charging station body, a charging cable connected to the charging station body, a charging gun connected to the end of the charging cable, and a cable retraction assembly on the charging station body. The cable retraction assembly consists of a lifting structure and a cable retraction structure. The lifting structure includes a mounting base fixed to the back of the charging station body. An opening is provided on the side of the mounting base. A linear actuator is installed inside the mounting base. A linear slide is slidably mounted on the linear actuator. A connecting rod is fixed to the side of the linear slide. The end of the connecting rod away from the linear slide passes through the opening and slides in the opening. The cable retraction structure includes a slide rail fixed to the end of the connecting rod away from the linear slide.

[0008] As a preferred embodiment of the present invention, the cable take-up structure further includes a plurality of sliders and a first tension spring. The plurality of sliders are slidably disposed on a slide rail, and a rope buckle is fixed on the bottom surface of each slider. One end of the first tension spring is connected to the charging pile body, and the other end of the first tension spring is connected to a slider away from the connecting rod.

[0009] As a preferred embodiment of the present invention, the charging cable passes through a plurality of loops, and the plurality of loops are arranged in a linear array on the charging cable.

[0010] As a preferred embodiment of the present invention, the slide rail has an installation opening, a vertical rod is fixed on the slider away from the connecting rod, the vertical rod extends into the installation opening and slides in the installation opening, a cylinder is installed inside the charging pile body, a locking rod is fixed to the telescopic end of the cylinder, a through-hole is opened on the side of the charging pile body, the locking rod passes through the through-hole and slides in the through-hole.

[0011] As a preferred embodiment of the present invention, a cleaning component is provided on one side of the charging pile body for cleaning the charging cable. The cleaning component includes a fixing cover, which is located on one side of the charging pile body and is fixedly connected to the top of the charging pile body through a connecting frame. A motor is installed inside the fixing cover, and two rotating rollers are rotatably installed inside the fixing cover. The two rotating rollers are connected by a cleaning belt. The surface of the cleaning belt is covered with bristles, and the output shaft of the motor is connected to one of the rotating rollers.

[0012] As a preferred embodiment of the present invention, the bristles are made of plastic material.

[0013] As a preferred embodiment of the present invention, the motor is treated with moisture-proof and waterproof measures.

[0014] As a preferred embodiment of the present invention, the output shaft of the motor is fixed with a fixed plate, the top surface of the fixed plate is fixed with a side plate, a vibration assembly is provided on the slide rail, the vibration assembly includes a fixed frame, the fixed frame is fixed on the top surface of the slide rail, a slide rod is slidably provided on the fixed frame, the slide rod is connected to the slide rail by a second tension spring, and a fixed rod is fixed at the end of the slide rod away from the vertical rod.

[0015] In a preferred embodiment of the present invention, the sliding rod is positioned directly opposite the vertical rod.

[0016] As a preferred embodiment of the present invention, the fixing rod is located on the rotation path of the side plate.

[0017] The present invention has the following beneficial effects:

[0018] 1. By combining the lifting structure and the cable retraction structure, the charging cable can be automatically retracted and unfolded. After charging is completed, the charging cable is placed in an orderly manner off the ground to avoid the cable from scattering everywhere, thus extending the service life of the charging cable. At the same time, it keeps the charging area clean and improves the convenience of use.

[0019] 2. By using the locking rod and the vertical rod together, the slider is locked when not charging, preventing the charging cable from being accidentally pulled out, limiting the range of movement of the charging gun, and avoiding damage to the charging gun or dangerous situations caused by misoperation or external force, thus enhancing the safety of the charging pile.

[0020] 3. A cleaning component is installed. When the charging cable is stored, the motor drives the cleaning belt to rotate. The bristles on its surface can brush the charging cable to effectively remove snow, mud and other stains, keep the charging cable clean, and ensure the safety and stability of the charging process.

[0021] 4. Through the design of the vibration component, the motor drives the fixed plate to rotate, and the side plate periodically pushes the fixed rod, causing the slide bar to vibrate, which in turn drives the slider and charging gun to vibrate. Combined with the brush bristles, it further shakes off the deposits on the surface of the charging gun, significantly improving the cleaning effect. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1: This example describes an automatic charging station with retractable charging cable, as disclosed in this example. Figure 1 , Figure 5 , Figure 6 and Figure 8 The system includes a charging pile body 1, a charging cable 11 connected to the charging pile body 1, a charging gun 12 connected to the end of the charging cable 11, a socket for inserting the charging gun 12 on the charging pile body 1, and the charging gun 12 being inserted into the socket under normal conditions. The charging pile body 1 is equipped with a cable winding assembly, which consists of a lifting structure and a cable winding structure. The lifting structure includes a mounting base 2, which is fixed to the back of the charging pile body 1. An opening 21 is provided on the side of the mounting base 2. The opening 21 is elongated and is set along the height direction of the mounting base 2. A linear actuator 22 is installed inside the mounting base 2. A linear slide 221 is slidably mounted on the linear actuator 22. A connecting rod 222 is fixed on the side of the linear slide 221. The end of the connecting rod 222 away from the linear slide 221 passes through the opening 21 and slides in the opening 21. When the linear actuator 22 is running, the linear slide 221 drives the connecting rod 222 to move up and down.

[0034] The cable retraction structure includes a slide rail 31 and a first tension spring 34. The slide rail 31 is fixed to the end of the connecting rod 222 away from the linear slide block 221. Several sliders 32 are slidably arranged on the slide rail 31. Each slider 32 has a rope buckle 33 fixed to its bottom surface. The charging cable 11 passes through the rope buckles 33, which are arranged in a linear array on the charging cable 11. One end of the first tension spring 34 is connected to the charging pile body 1, and the other end is connected to the sliders 32 away from the connecting rod 222. Under the elastic force of the first tension spring 34, the sliders 32 are in a retracted state, at which time the charging cable 11 is gathered together, forming a... Figure 5In the state shown, the charging cable 11 is off the ground and arranged in an orderly manner, achieving storage of the charging cable 11. When the user charges, the user unlocks the charging gun 12, and the linear actuator 22 operates accordingly. In the initial state, the linear slide 221 is located at the top of the mounting base 2. When the linear actuator 22 operates, the linear slide 221 moves downward, and drives the slide rail 31 downward through the connecting rod 222. When the slide rail 31 descends, the charging cable 11 on it descends accordingly until the slide rail 31 descends to the middle position of the charging pile body 1. Then, the user pulls the charging gun 12 to start charging. When the charging gun 12 is pulled, the charging gun 12 pulls the charging cable 11, causing the charging cable 11 to pull several rope buckles 33, which in turn causes several sliders 32 to slide and spread out on the slide rail 31. In this case, the charging cable 11 can be stretched, making it convenient for the user to charge. After charging is completed, the linear actuator 22 drives the linear slide block 221 to reset, causing the slide rail 31 to move upward. When the slide rail 31 moves upward, the charging cable 11 moves away from the ground. At the same time, the first tension spring 34 drives the corresponding slider 32 to move, causing several sliders 32 to retract, and finally retracting the charging cable 11, realizing the automatic storage of the charging cable 11.

[0035] The implementation principle of this embodiment is as follows: The cable retraction assembly of the automatic cable retraction charging pile consists of a lifting structure and a cable retraction structure. In the lifting structure, the mounting base 2 is fixed to the back of the charging pile body 1. When the linear actuator 22 inside it runs, it drives the linear slide 221 to move up and down. The linear slide 221 drives the slide rail 31 to rise and fall through the connecting rod 222. In the cable retraction structure, several sliders 32 with rope buckles 33 are slidably arranged on the slide rail 31. The charging cable 11 passes through the rope buckle 33 and one end is connected to the charging gun 12. One end of the first tension spring 34 is connected to the other end of the charging pile body 1. The slider 32, which is connected away from the connecting rod 222, is normally closed by the first tension spring 34, which causes the slider 32 to retract and the charging cable 11 to gather and lift off the ground. When the user is charging, the charging gun 12 is unlocked, and the linear actuator 22 operates to lower the slide rail 31 to the middle. The user pulls the charging gun 12, which causes the charging cable 11 to pull the cord buckle 33. The slider 32 slides and spreads on the slide rail 31, and the charging cable 11 is stretched to facilitate charging. After charging is completed, the linear actuator 22 drives the slide rail 31 to move upward, and the first tension spring 34 drives the slider 32 to retract, and the charging cable 11 retracts to achieve automatic storage.

[0036] Example 2: Based on Example 1, this example discloses an automatic charging station with retractable charging cable, such as... Figure 4 and Figure 5 As shown, the slide rail 31 has an installation port 311. A vertical rod 321 is fixed on the slider 32 away from the connecting rod 222. The vertical rod 321 extends into the installation port 311 and slides in the installation port 311. A cylinder 41 is installed inside the charging pile body 1. A locking rod 42 is fixed to the telescopic end of the cylinder 41. A through-hole is opened on the side of the charging pile body 1. The locking rod 42 passes through the through-hole and slides in the through-hole.

[0037] The implementation principle of this embodiment is as follows: In the initial state, the slide rail 31 is located at the top of the charging pile body 1, and several sliders 32 are in a gathered state. At this time, the vertical rod 321 is located on one side of the locking rod 42, forming a shape like... Figure 5 In the state shown, the locking lever 42 blocks the vertical lever 321. When the charging gun 12 is pulled, the sliders 32 cannot slide on the slide rail 31. This design prevents the charging cable 11 from being pulled out, thus limiting the range of movement of the charging gun 12 and achieving locking protection for the charging gun 12. When the user unlocks the charging pile body 1, the slide rail 31 drives the sliders 32 to move downward, and the vertical lever 321 also moves downward. At this time, the vertical lever 321 will be misaligned with the locking lever 42, and the locking lever 42 no longer restrains the sliders 32. This allows the charging cable 11 to unfold freely, facilitating normal charging operations.

[0038] Example 3: Based on Example 2, this example discloses an automatic charging station with retractable charging cable, such as... Figure 2 , Figure 4 and Figure 9 As shown, a cleaning component is provided on one side of the charging pile body 1 for cleaning the charging cable 11. The cleaning component includes a fixing cover 51, which is located on one side of the charging pile body 1 and is fixedly connected to the top of the charging pile body 1 through a connecting bracket 511. A motor 52 is installed inside the fixing cover 51. The motor 52 is treated with moisture-proof and waterproof measures to enable it to operate stably in outdoor environments. The specific treatment measures are existing technology and will not be described in detail here. Two rotating rollers 53 are rotatably installed inside the fixing cover 51. The two rotating rollers 53 are connected by a cleaning belt 54. The surface of the cleaning belt 54 is covered with bristles 55. The output shaft of the motor 52 is connected to one of the rotating rollers 53.

[0039] The implementation principle of this embodiment is as follows: The charging pile proposed in this invention not only has the function of storing the charging cable 11, but also has the function of cleaning the charging cable 11. Specifically, when the charging cable 11 is in the stored state, the device can actively clean the charging cable 11. During cleaning, the motor 52 starts and drives the corresponding rotating roller 53 to rotate. The two rotating rollers 53 are connected by a cleaning belt 54. Therefore, the two rotating rollers 53 can drive the cleaning belt 54 to rotate. During the rotation of the cleaning belt 54, the bristles 55 on its surface can continuously brush the charging cable 11. When there is snow or mud on the surface of the charging cable 11, the brushing of the bristles 55 can clean the charging cable 11.

[0040] Example 4: Based on Example 3, this example discloses an automatic charging station with retractable charging cable, such as... Figure 3 and Figure 7 As shown, the output shaft of the motor 52 is fixed with a fixed plate 521, and a side plate 522 is fixed on the top surface of the fixed plate 521. A vibration assembly is provided on the slide rail 31. The vibration assembly includes a fixed frame 61, which is fixed on the top surface of the slide rail 31. A slide rod 62 is slidably arranged on the fixed frame 61, and the slide rod 62 is positioned directly opposite the vertical rod 321. The slide rod 62 is connected to the slide rail 31 by a second tension spring 63. A fixed rod 621 is fixed to the end of the slide rod 62 away from the vertical rod 321, and the fixed rod 621 is located on the rotation path of the side plate 522.

[0041] When the cleaning component cleans the charging cable 11, the telescopic end of the cylinder 41 automatically retracts until the locking rod 42 retracts into the charging pile body 1. Without the constraint of the locking rod 42, several sliders 32 can slide freely on the slide rail 31. In addition, while the motor 52 drives the cleaning belt 54 to rotate, the motor 52 can also drive the fixed plate 521 to rotate. The side plate 522 on the fixed plate 521 rotates accordingly. During the rotation, the side plate 522 can periodically push the fixed rod 621. When the fixed rod 621 is pushed by the side plate 522, the fixed rod 621 drives the sliding rod 62 to move, and at the same time stretches the second tension spring 63. When the fixed rod 621... When separated from the side plate 522, the slide rod 62 returns to its original position under the action of the second tension spring 63. Therefore, under the pushing action of the side plate 522, the slide rod 62 vibrates on the slide rail 31. The vibration of the slide rod 62 is transmitted to the vertical rod 321, which ultimately drives the slider 32 away from the connecting rod 222 to vibrate. When one of the sliders 32 vibrates, the vibrating slider 32 can drive the other sliders 32 to vibrate through the charging cable 11, which ultimately causes the charging gun 12 to vibrate. When the charging gun 12 vibrates, the snow and mud attached to the surface can be shaken off. At the same time, with the brushing action of the bristles 55, the cleaning effect of the device on the charging cable 11 is further improved.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
