Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile cable storage device. Background Technology

[0002] With the increasing popularity of electric vehicles, there are more and more outdoor charging stations. Charging stations generally require charging guns for charging, and charging guns require charging cables for power. However, if charging cables are exposed to the outside for a long time, they are easily damaged due to pulling, wear and tear from the ground, and exposure to the sun. Therefore, they need to be properly stored when not in use to extend the service life of the charging cables.

[0003] A utility model patent with publication number CN212403029U provides a cable storage mechanism for charging piles used in new energy vehicles, which can automatically retract the cable into the charging pile by squeezing it with a spring. However, during the repeated retraction of the charging cable, the lack of a reasonable dust cleaning structure allows dust to accumulate in the storage cavity, jamming the charging cable and preventing normal retraction. Furthermore, the use of a single spring to pull the charging cable has limited storage capacity, and there are no remedial measures for spring failure. Therefore, it is difficult to meet the cable storage needs of existing charging piles. Utility Model Content

[0004] The purpose of this utility model is to provide a charging pile cable storage device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charging pile cable storage device, comprising:

[0006] A storage housing is fixed on a charging pile and used to hold a charging gun. The charging gun is connected to a charging cable that is electrically connected to a power supply component inside the charging pile. The storage housing also has a storage cavity inside.

Detailed Implementation

[0025] To clearly and completely describe the objectives and technical solutions of this utility model, and to more clearly illustrate its advantages, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4This utility model provides a charging pile cable storage device, including a storage housing 1, a cable pulling device 4, and a cleaning device 3. The storage housing 1 is fixed on the charging pile and is used to hold a charging gun 7. The charging gun 7 is connected to a charging cable 8 that is electrically connected to the power supply component inside the charging pile. The storage housing 1 is provided with a storage cavity 21. The cable pulling device 4 includes a fixed plate 404 fixed to the bottom of the storage cavity 21 and a movable plate 401 that slides up and down along the storage cavity 21. A pulley group 403 for pulling the charging cable 8 is provided between the fixed plate 404 and the movable plate 401. A second return spring 402 for resetting the movable plate 401 is provided between the fixed plate 404 and the movable plate 401. The storage cavity 21 is provided with... A slide rail 20 guides the movement of the movable plate 401, and a slider 13 is fixedly installed on the movable plate 401, sliding along the slide rail 20. When the user needs to charge the device with the charging gun 7, the user removes the charging gun 7 from the storage housing 1, and then pulls the charging cable 8 outward, causing the movable plate 401 to move towards the bottom of the storage cavity 21, allowing the charging cable 8 to be pulled out to the required length. When the user stops pulling the charging cable 8, the second return spring 402 pushes the movable plate 401 upward, causing the charging cable 8 to retract into the storage cavity 21 under the traction of the pulley group 403. After the user finishes charging, the user simply puts the charging gun 7 back into the storage housing 1. Furthermore, the device can increase the amount of charging cable 8 that can be stored using the pulley group 403, thus enabling the storage of longer charging cables.

[0027] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5The bottom of the housing 1 is provided with a discharge chamber 16, and a cleaning device 3 is provided inside the discharge chamber 16. The cleaning device 3 includes a cleaning roller 301 rotatably mounted with the housing 1, and a cleaning brush 302 fixed on the cleaning roller 301, which can clean the dust on the charging cable 8 by rotating. At the junction of the corresponding storage chamber 21 and the discharge chamber 16, the housing 1 is provided with a scraper ring 18 sleeved on the charging cable 8 to scrape the dust on the surface of the charging cable 8. At the end of the corresponding scraper ring 18, the storage chamber 21 is provided with a reversing pulley 19 for guiding the charging cable 8 from the discharge chamber 16 to the pulley group 403. The reversing pulley 19 drives the cleaning device 3 to rotate through a reversing drive device 5. The reversing drive device 5 includes a first bevel gear 501 coaxially mounted with the reversing pulley 19, and a belt-driven cleaning device is rotatably mounted on the housing 1. The drive wheel 503 of the rotating drum 301 has a second bevel gear 502 coaxially mounted on it, meshing with the first bevel gear 501. During the movement of the charging cable 8, the drive wheel 503 will drive the reversing pulley 19, which in turn will drive the first bevel gear 501. The first bevel gear 501 will then drive the drive wheel 503 via the second bevel gear 502. Subsequently, the drive wheel 503 will drive the cleaning drum 301 to rotate via a belt. When the cleaning drum 301 rotates, the cleaning brushes 302 inside the cleaning drum 301 will scrape the surface of the charging cable 8, thus ensuring the cleanliness of the charging cable 8. The gaps between the cleaning brushes 302 allow the scraped dust to fall to the outside through the bottom of the discharge chamber 16. The charging cable 8 will also be scraped by the scraping ring 18, thus ensuring that the surface of the charging cable 8 is clean. By cleaning the charging cable 8 in this way, it is possible to effectively prevent dust and other impurities from being carried into the storage cavity 21 by the charging cable 8, and effectively prevent the cable pulling device 4 from getting stuck due to dust.

[0028] Example 2: Please refer to Figure 1 , Figure 2 and Figure 4Based on Embodiment 1, a controller 10 is fixedly installed on the housing 1, and a positioning switch 6 for detecting whether the charging gun 7 is correctly placed on the housing 1 is fixedly installed on the charging gun 7. A limit push rod 11 is fixedly installed on the movable plate 401, and the output end of the limit push rod 11 drives a pressing block 12 that presses against the inner wall of the storage cavity 21 and is used to limit the displacement of the movable plate 401. The controller 10 is electrically connected to the charging gun 7, the positioning switch 6, and the limit push rod 11 respectively. When the controller 10 detects that the charging gun 7 is in a normal charging state, the controller 10 will drive the limit push rod 11 to press the pressing block. The 12 is pressed against the inner wall of the storage cavity 21, thereby restricting the movement of the movable plate 401 and preventing the charging cable 8 from being pulled back into the storage cavity 21 by the cable pulling device 4. This avoids the problem of the charging gun 7 falling off due to the cable pulling device 4 pulling the charging cable 8 during normal charging. When the charging is completed, when the user correctly places the charging gun 7 on the storage housing 1, the positioning switch 6 will be triggered. At this time, the controller 10 controls the limit push rod 11 to move in the opposite direction, thereby causing the pressing block 12 to disengage from the contact state with the inner wall of the storage cavity 21. This allows the cable pulling device 4 to normally retract the charging cable 8 into the storage cavity 21.

[0029] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3Based on Embodiment 2, a rack 17 is installed vertically inside the storage cavity 21, and a main motor 14 is fixedly installed on the movable plate 401. The output end of the main motor 14 drives a main gear 15 that meshes with the rack 17, and the main motor 14 is used to drive the movable plate 401 to move up and down. The controller 10 is electrically connected to the main motor 14. A limiting guide device 2 for limiting the charging cable 8 is provided at the inlet end of the discharge cavity 16. The limiting guide device 2 includes a connecting plate 201 fixed to the storage shell 1, and a guide is connected to the connecting plate 201 through a first return spring 204. The frame 203 guides the charging cable 8 into the cleaning roller 301. A pressure sensor 205 is mounted on the connecting plate 201 to detect the force on the first return spring 204. A limiting block 9 for pushing the guide frame 203 is fixed at a designated retraction stop position for the charging cable 8. The pressure sensor 205 is electrically connected to the controller 10. A first elastic membrane 202 and a second elastic membrane 206 are provided between the connecting plate 201 and the guide frame 203 to seal the first return spring 204. The first elastic membrane 202 contacts the limiting block 9. Both the first elastic membrane 202 and the second elastic membrane 206 can be made of rubber. The first elastic membrane 202 has a thicker surface and, if necessary, a metal sheet is provided inside the first elastic membrane 202 for support, thereby ensuring a stable relative position between the connecting plate 201 and the guide frame 203, allowing the limiting block 9 to press correctly onto the guide frame 203. When the limiting block 9 presses onto the guide frame 203, the pressure on the pressure sensor 205 reaches the threshold. The controller 10 will then lock the position of the movable plate 401 again via the limiting push rod 11 to prevent the charging gun 7 from being pulled too much and to prevent children from pulling out the cable. The locking state will only be released when the user removes the charging gun 7 from the storage housing 1 and the positioning switch 6 is not triggered. In addition, considering that the second reset spring 402 may fail and result in insufficient rebound force, making it impossible to fully retract the charging cable 8, the controller 10 will start timing after the user correctly places the charging gun 7 on the storage housing 1 and triggers the positioning switch 6. Within the preset timing period, if the limiting block 9 fails to properly press the guide frame 203 and trigger the pressure sensor 205, the controller 10 will control the main motor 14 to directly drive the main gear 15 to rotate. The main gear 15 will then drive the movable plate 401 upward along the rack 17 until the pressure sensor 205 is correctly triggered. This method effectively avoids problems such as the charging cable 8 not being properly stored in the storage cavity 21 or the charging cable 8 being easily pulled out by children, thus better protecting the charging cable 8.
