Technical Field
[0001] This utility model belongs to the field of charging pile technology, specifically relating to a cable routing mechanism for a charging pile cable retraction device. Background Technology
[0002] Charging stations, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. When charging an electric vehicle, the charging gun needs to be unplugged from the charging station's mounting box. Because the car's charging interface is low to the ground, using the charging gun requires dragging the charging cable. The charging cable is long and heavy, making this time-consuming, laborious, and difficult to operate. Furthermore, each time the cable is charged, its insulation layer rubs against the ground, causing damage and shortening its lifespan, potentially leading to safety hazards. Therefore, charging stations with cable retraction mechanisms have emerged on the market.
[0003] The existing cable winding mechanism of the cable winding device has limited constraints on the charging cable, and cannot ensure that the charging cable can be neatly wound on the cable reel. It is easy for the charging cable to get tangled or messy, which makes it impossible for the charging cable of the charging gun to be retracted and used normally. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a cable routing mechanism for a charging pile cable retraction device, which can effectively solve the problems of charging cables being knotted and tangled, and ensure the normal extension and retraction of the charging cables.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cable routing mechanism for a charging pile cable winding device includes a housing and a winding reel and a lead screw rotatably disposed within the housing. The lead screw is rotatably disposed within the housing along the axial direction of the winding reel. The lead screw is linked to the winding reel, and the driving force of the winding reel causes the lead screw to rotate within the housing. A cable routing plate threadedly connected to the lead screw is slidably disposed within the housing. The driving force of the lead screw causes the cable routing plate to reciprocate within the housing along the axial direction of the winding reel. A guide groove for the cable to pass through is provided on the side of the cable routing plate facing the winding reel.
[0006] In some embodiments, a support column is provided inside the housing along the axial direction of the winding reel, and a guide hole is provided on the cable tray. The support column is inserted into the guide hole, and a sliding connection is formed between the cable tray and the support column.
[0007] In some embodiments, a bushing that abuts against the cable is provided in the guide groove, and the bushing is slidably mounted on the support column.
[0008] In some embodiments, a gear is provided on the lead screw, and a large gear that meshes with the gear is provided on the winding reel.
[0009] In some embodiments, the housing is provided with a micro switch assembly that cooperates with the ribbon cable board. The micro switch assembly includes a support plate disposed in the housing and a first micro switch and a second micro switch. The first micro switch and the second micro switch are respectively disposed on both ends of the support plate. The ribbon cable board moves with the lead screw and triggers the first micro switch and the second micro switch respectively, thereby realizing the connection or disconnection of the first micro switch and the second micro switch.
[0010] In some embodiments, one end of the ribbon cable board has a protrusion for triggering a first micro switch and a second micro switch.
[0011] In some embodiments, a spiral-shaped partition is provided on the outer peripheral wall of the reel, and a spiral-shaped clamping groove for placing cables is formed between the partition and the outer peripheral wall of the reel.
[0012] In some embodiments, the partition is provided with a plurality of protrusions on both sides that abut against the cable.
[0013] In some embodiments, the outer peripheral wall of the winding reel is provided with a spiral-shaped snap-fit groove, and the partition is snapped into the snap-fit groove.
[0014] In some embodiments, the housing is provided with a pressing wheel assembly for pressing the cable into the clamping groove. The pressing wheel assembly includes a support rod and a plurality of pressing wheels for pressing the cable into the clamping groove. The plurality of pressing wheels are respectively rotatably mounted on the support rod along the axial direction of the cable reel.
[0015] The beneficial effects of this utility model are as follows: The cable laying mechanism adopts a screw drive structure design, and the cable laying plate plays a guiding role in the laying and winding of the cable, thereby ensuring that the cable laying is orderly during the laying and winding process, effectively avoiding the problems of cable knotting and tangling, ensuring the normal extension and retraction of the cable, and helping to improve the laying and winding efficiency of the cable.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:
[0025] like Figure 1 , 2As shown, a cable routing mechanism for a charging pile cable winding device includes a housing 1, a winding reel 2 rotatably disposed within the housing 1, and a lead screw 3. The lead screw 3 is rotatably disposed within the housing 1 along the axial direction of the winding reel 2. The lead screw 3 and the winding reel 2 are linked and cooperate, and the driving force of the winding reel 2 causes the lead screw 3 to rotate within the housing 1. A cable routing plate 4, threadedly connected to the lead screw 3, is slidably disposed within the housing 1. The driving force of the lead screw 3 causes the cable routing plate 4 to reciprocate within the housing 1 along the axial direction of the winding reel 2. A guide groove 41 is provided on the side of the cable routing plate 4 facing the winding reel 2, allowing the cable to pass through. A support column 5 is provided within the housing 1 along the axial direction of the winding reel 2. A guide hole 42 is provided on the cable routing plate 4, and the support column 5 is inserted into the guide hole 42, forming a sliding connection between the cable routing plate 4 and the support column 5. The support column guides the cable routing plate, allowing the cable routing plate to slide along the support column and achieve orderly cable routing, preventing the cable from tangling or becoming messy. A bushing 6 is installed inside the guide groove 41, abutting against the cable. The bushing is slidably mounted on the support column 5. The bushing in contact with the cable within the guide groove serves as a guide, ensuring the cable can be wound and unwound in an orderly manner. A gear 7 is linked to the lead screw 3, and a large gear 8 meshing with the gear 7 is installed on the reel 2. The reel and the lead screw are driven by gears, ensuring that the reel can reliably drive the lead screw to rotate, resulting in more reliable and stable transmission.
[0026] like Figure 2 As shown, the housing 1 contains a micro switch assembly 9 that works in conjunction with the cable tray 4. The micro switch assembly 9 includes a support plate 91, a first micro switch 92, and a second micro switch 93, all housed within the housing 1. The first and second micro switches 92 and 93 are respectively positioned at both ends of the support plate 91. The cable tray 4 moves with the lead screw 3, triggering the first and second micro switches 92 and 93 respectively, thus enabling their connection or disconnection. The first and second micro switches monitor the position of the cable tray, thereby controlling the cable winding and unwinding limits of the reel, improving the reliability of the winding and unwinding process. When the cable reaches its limit position (complete retraction), the cable tray triggers the first micro switch, which sends the detected limit winding signal to the control circuit board. The control circuit board then stops the motor, thus stopping the cable winding and unwinding device. When the cable is laid out to its limit (fully extended), the second microswitch sends the detected limit signal to the control circuit board. The control circuit board then stops the motor, thereby stopping the cable winding and unwinding device. One end of the cable tray 4 has a protrusion 43 for triggering the first microswitch 92 and the second microswitch 93. The cable tray triggers the first and second microswitches via the protrusion, which improves the reliability of the microswitch assembly.
[0027] like Figure 3 and 4As shown, a spiral-shaped partition 10 is provided on the outer peripheral wall of the cable reel 2. A spiral-shaped clamping groove 200 for placing cables is formed between the partition 10 and the outer peripheral wall of the cable reel 2. The partition limits the cable and ensures that the cable can be wound orderly on the cable reel, which helps to improve the reliability of cable winding and unwinding. Multiple protrusions 101 are provided on both sides of the partition 10 to abut against the cable. The protrusions can increase the clamping force of the partition on the cable and ensure that the cable can be reliably wound on the cable reel. A spiral-shaped snap-fit groove 21 is provided on the outer peripheral wall of the cable reel 2, and the partition 10 is snapped into the snap-fit groove 21. The cable reel and the partition are engaged by a snap-fit method, which facilitates the assembly of the partition and the cable reel and improves the assembly efficiency.
[0028] like Figure 2 , 3 As shown, the housing 1 is equipped with a wire pressing wheel assembly 11 for pressing the cable into the clamping groove 200. The wire pressing wheel assembly 11 includes a support rod 111 and multiple wire pressing wheels 112 for pressing the cable into the clamping groove 200. The multiple wire pressing wheels 112 are rotatably mounted on the support rod 111 along the axial direction of the winding reel 2. The wire pressing wheel assembly limits the cable position. When winding the cable, the wire pressing wheels can press the cable into the clamping groove, ensuring that the cable can be reliably wound on the winding reel.
[0029] The cable routing mechanism adopts a screw drive structure design, and the cable routing plate guides the cable winding and unwinding, thereby ensuring orderly cable routing during the winding and unwinding process. This effectively avoids cable tangling and tangling, ensures normal cable extension and retraction, and helps improve cable winding and unwinding efficiency.
[0030] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
