Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to an automatic cable collection device for charging piles. Background Technology

[0002] A charging pile refers to the charging equipment that provides charging services for electric vehicles. Currently, the charging cable of a charging pile is exposed on the outside of the pile body, wound around both sides of the pile body via a bracket. During use, the cable is stretched through the plug at the end to charge the vehicle. However, the charging cable is prone to tangling and twisting when wound around the bracket, and the exposed cable poses many safety hazards. High pedestrian traffic near the charging pile could lead to contact with or running over the cable, causing damage. To solve this technical problem, those skilled in the art have implemented a winding mechanism on the charging pile for winding the charging cable. This mechanism releases the cable during charging and winds it up after charging is complete, as seen in a charging pile with application number CN202211354453.5. However, using a winding method for cable management requires repeated bending, winding, and unwinding of the charging cable during reuse, which can easily damage the cable due to repeated bending. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic cable collection device for charging piles, which can organize the charging cables of charging piles and avoid damage caused by excessive bending of the charging cables.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An automatic cable hub device for charging piles includes a charging pile, a hub box installed on one side wall of the charging pile, a hub frame installed inside the hub box, and the charging cable of the charging pile passing around the hub frame and exiting the hub box.

[0006] The cable tray includes a double-ended lead screw rotatably connected to the top and bottom of the cable tray cavity, with the threads at both ends of the double-ended lead screw in opposite directions. Slider blocks are threaded to the outer walls of both opposite ends of the double-ended lead screw. A mounting base is fixed to one side of each slider, and a winding wheel assembly for the charging cable to pass over is mounted on one side of the mounting base. A driven gear is fixed to the outer wall of one end of the double-ended lead screw. A drive motor is installed at the bottom of the cable tray cavity, and a driving gear that meshes with the driven gear is fixed to the outer wall of the output end of the drive motor.

[0007] Furthermore, the winding wheel assembly includes a rotating shaft and a fixed shaft. The rotating shaft is rotatably connected to the mounting base, and a winding wheel is fixedly connected to the outer wall of the rotating shaft. The fixed shaft is fixedly connected to the mounting base, and a pressure wheel is rotatably connected to the outer wall of the fixed shaft. The charging cable passes through the gap between the winding wheel and the pressure wheel.

[0008] Furthermore, both the winding wheel and the pressure wheel include a wheel body, and the wheel body is symmetrically provided with a first retaining ring on opposite sides, and the diameter of the first retaining ring is larger than the diameter of the wheel body. The first retaining ring of the winding wheel and the first retaining ring of the pressure wheel abut against each other.

[0009] Furthermore, two limiting slide rails are installed parallel to each other on the side of the hub box near the charging pile, and both mounting seats are slidably connected to the two limiting slide rails.

[0010] Furthermore, one end of the rotating shaft passes through the mounting base and is equipped with a rotating gear. The side wall of the limiting slide rail is provided with a rack that cooperates with the rotating gear. When the two sliders slide in a direction that approaches each other, the meshing of the rotating gear and the rack drives the winding wheel to rotate in the direction that the charging cable is pulled out.

[0011] Furthermore, one side of the junction box is provided with a through hole for the charging cable to pass through, and the inner wall of the through hole is provided with a rubber protective sleeve.

[0012] Furthermore, the inner cavity of the hub box is provided with two sets of elastic limiting wheel assemblies through which the charging cables pass, with the two sets of limiting wheel assemblies respectively close to the lead-out end and lead-in end of the charging cable.

[0013] Furthermore, the elastic limiting wheel assembly includes two symmetrically arranged elastic fixing seats, and two limiting wheels are rotatably connected between the two elastic fixing seats, with the charging cable passing between the two limiting wheels.

[0014] Furthermore, the limiting wheel is symmetrically provided with second retaining rings on its opposite two sides, and the diameter of the second retaining rings is larger than the diameter of the limiting wheel.

[0015] Furthermore, the elastic fixing seat includes a concave fixing seat, and the openings of the two concave fixing seats are arranged opposite to each other. A limiting rod is installed between the opposite side walls of the inner cavity of the concave fixing seat. Two limiting mounting blocks are slidably connected to the outer wall of the limiting rod. A spring is connected between the two limiting mounting blocks, and the spring is sleeved on the outer wall of the limiting rod. The limiting wheel is rotatably installed between the two oppositely arranged limiting mounting blocks.

[0016] The beneficial effects of this utility model are as follows:

[0017] After the charging station is fully charged, this invention can drive the double-headed lead screw to rotate via a drive motor, causing the two winding wheel assemblies to slide in opposite directions. This gradually tauts the charging cable inside the junction box, pulling the charging cable outside the junction box back inside for collection and organization, preventing it from being exposed and posing various risks. Furthermore, the winding wheel assembly tauts the charging cable during collection, eliminating the need for rewinding and preventing damage caused by repeated rewinding. Attached Figure Description

Detailed Implementation

[0026] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figure 1-6As shown, an automatic cable hub device for a charging pile includes a charging pile, a hub box installed on one side wall of the charging pile, a hub frame installed inside the hub box, and the charging cable of the charging pile passing around the hub frame and exiting the hub box.

[0028] The cable tray includes a double-ended lead screw rotatably connected to the top and bottom of the cable tray cavity, with the threads at both ends of the double-ended lead screw in opposite directions. Slider blocks are threaded to the outer walls of both opposite ends of the double-ended lead screw. A mounting base is fixed to one side of each slider, and a winding wheel assembly for the charging cable to pass over is mounted on one side of the mounting base. A driven gear is fixed to the outer wall of one end of the double-ended lead screw. A drive motor is installed at the bottom of the cable tray cavity, and a driving gear that meshes with the driven gear is fixed to the outer wall of the output end of the drive motor.

[0029] As can be seen from the above description, the beneficial effects of this utility model are as follows:

[0030] After the charging station is fully charged, this invention can drive the double-headed lead screw to rotate via a drive motor, causing the two winding wheel assemblies to slide in opposite directions. This gradually tauts the charging cable inside the junction box, pulling the charging cable outside the junction box back inside for collection and organization, preventing it from being exposed and posing various risks. Furthermore, the winding wheel assembly tauts the charging cable during collection, eliminating the need for rewinding and preventing damage caused by repeated rewinding.

[0031] Furthermore, the winding wheel assembly includes a rotating shaft and a fixed shaft. The rotating shaft is rotatably connected to the mounting base, and a winding wheel is fixedly connected to the outer wall of the rotating shaft. The fixed shaft is fixedly connected to the mounting base, and a pressure wheel is rotatably connected to the outer wall of the fixed shaft. The charging cable passes through the gap between the winding wheel and the pressure wheel.

[0032] As can be seen from the above description, the setting of the pressure roller can prevent the cable from falling off the winding wheel, so that the charging cable can always be in close contact with the winding wheel during the sliding process of the winding wheel.

[0033] Furthermore, both the winding wheel and the pressure wheel include a wheel body, and the wheel body is symmetrically provided with a first retaining ring on opposite sides, and the diameter of the first retaining ring is larger than the diameter of the wheel body. The first retaining ring of the winding wheel and the first retaining ring of the pressure wheel abut against each other.

[0034] As described above, the first retaining ring creates a gap between the winding wheel and the pressure wheel, allowing the charging cable to pass through. At the same time, the first retaining ring prevents the charging cable from falling off from both sides of the winding wheel and the pressure wheel.

[0035] Furthermore, two limiting slide rails are installed parallel to each other on the side of the hub box near the charging pile, and both mounting seats are slidably connected to the two limiting slide rails.

[0036] As can be seen from the above description, the setting of the limit slide rail can limit the sliding of the mounting base.

[0037] Furthermore, one end of the rotating shaft passes through the mounting base and is equipped with a rotating gear. The side wall of the limiting slide rail is provided with a rack that cooperates with the rotating gear. When the two sliders slide in a direction that approaches each other, the meshing of the rotating gear and the rack drives the winding wheel to rotate in the direction that the charging cable is pulled out.

[0038] As described above, the rotation of the gear and rack allows the winding wheel to rotate during the sliding motion of the mounting base, with the rotation directions being opposite during the upward and downward movements. This assists in pulling out and retracting the charging cable.

[0039] Furthermore, one side of the junction box is provided with a through hole for the charging cable to pass through, and the inner wall of the through hole is provided with a rubber protective sleeve.

[0040] As described above, the rubber protective sleeve ensures a soft contact between the charging cable and the through hole, preventing damage to the charging cable.

[0041] Furthermore, the inner cavity of the hub box is provided with two sets of elastic limiting wheel assemblies through which the charging cables pass, with the two sets of limiting wheel assemblies respectively close to the lead-out end and lead-in end of the charging cable.

[0042] As described above, the elastic limit wheel assembly can act as a buffer for the charging cable, preventing it from being subjected to excessive tension.

[0043] Furthermore, the elastic limiting wheel assembly includes two symmetrically arranged elastic fixing seats, and two limiting wheels are rotatably connected between the two elastic fixing seats, with the charging cable passing between the two limiting wheels.

[0044] Furthermore, the limiting wheel is symmetrically provided with second retaining rings on its opposite two sides, and the diameter of the second retaining rings is larger than the diameter of the limiting wheel.

[0045] As can be seen from the above description, the second retaining ring can prevent the charging cable from falling off the limiting wheel.

[0046] Furthermore, the elastic fixing seat includes a concave fixing seat, and the openings of the two concave fixing seats are arranged opposite to each other. A limit rod is installed between the opposite side walls of the inner cavity of the concave fixing seat. Two limit mounting blocks are slidably connected to the outer wall of the limit rod. A spring is connected between the two limit mounting blocks, and the spring is sleeved on the outer wall of the limit rod. The limit wheel is rotatably installed between the two oppositely arranged limit mounting blocks.

[0047] As described above, when the limiting wheel is subjected to the force of the charging cable, it can drive the limiting mounting block to slide, thereby deforming the spring and thus playing a buffering role.

[0048] Please refer to Figures 1 to 6 As shown, Embodiment 1 of this utility model is as follows:

[0049] Please refer to Figure 1 and Figure 2 An automatic cable hub device for charging piles includes a charging pile 1, a hub box 2 installed on one side wall of the charging pile 1, a hub frame 3 provided inside the hub box 2, and the charging cable 11 of the charging pile 1 passing through the hub frame 3 and exiting the hub box 2.

[0050] The cable tray 3 includes a double-ended lead screw 31 rotatably connected to the top and bottom of the inner cavity of the cable tray 2, with the threads at both ends of the double-ended lead screw 31 having opposite directions. The outer walls of the opposite ends of the double-ended lead screw 31 are threaded with sliders 32. A mounting base 33 is fixedly connected to one side of the slider 32. A winding wheel assembly 34 for the charging cable 11 to pass over is mounted on one side of the mounting base 33. A driven gear 35 is fixedly connected to the outer wall of one end of the double-ended lead screw 31. A drive motor 36 is installed at the bottom of the inner cavity of the cable tray 2. A drive gear 37 that meshes with the driven gear 35 is fixedly connected to the outer wall of the output end of the drive motor 36.

[0051] Please refer to Figure 4 The winding wheel assembly 34 includes a rotating shaft 341 and a fixed shaft. The rotating shaft 341 is rotatably connected to the mounting base 33. A winding wheel 343 is fixedly connected to the outer wall of the rotating shaft 341. The fixed shaft is fixedly connected to the mounting base 33. A pressure wheel 344 is rotatably connected to the outer wall of the fixed shaft. The charging cable 11 passes through the gap between the winding wheel 343 and the pressure wheel 344.

[0052] Please refer to Figure 3 and Figure 4 Both the winding wheel 343 and the pressure wheel 344 include a wheel body. The wheel body is symmetrically provided with a first retaining ring 345 on its two opposite sides, and the diameter of the first retaining ring 345 is larger than the diameter of the wheel body. The first retaining ring 345 of the winding wheel 343 and the first retaining ring 345 of the pressure wheel 344 abut against each other.

[0053] Please refer to Figure 3 The junction box 2 is equipped with two limiting slide rails 38 installed in parallel on one side near the charging pile 1, and the two mounting seats 33 are slidably connected to the two limiting slide rails 38.

[0054] Please refer to Figure 3 and Figure 5One end of the rotating shaft 341 passes through the mounting base 33 and is equipped with a rotating gear 39. The side wall of the limiting slide rail 38 is provided with a rack 310 that cooperates with the rotating gear 39. When the two sliders 32 slide in a direction that approaches each other, the meshing of the rotating gear 39 and the rack 310 drives the winding wheel 343 to rotate in the direction that the charging cable 11 is pulled out.

[0055] The junction box 2 has a through hole on one side for the charging cable 11 to pass through, and the inner wall of the through hole is provided with a rubber protective sleeve.

[0056] Please refer to Figure 2 The inner cavity of the hub box 2 is provided with two sets of elastic limiting wheel assemblies 4 through which the charging cables 11 pass. The two sets of limiting wheel assemblies 42 are respectively close to the lead-out end and the lead-in end of the charging cables 11.

[0057] Please refer to Figure 4 The elastic limiting wheel assembly 4 includes two symmetrically arranged elastic fixing seats 41, and two limiting wheels 42 are rotatably connected between the two elastic fixing seats 41. The charging cable 11 passes through the two limiting wheels 42.

[0058] Please refer to Figure 4 The limiting wheel 42 has a second retaining ring 43 symmetrically arranged on its opposite two sides, and the diameter of the second retaining ring 43 is larger than the diameter of the limiting wheel 42.

[0059] Please refer to Figure 4 The elastic fixing seat 41 includes a concave fixing seat 411, and the openings of the two concave fixing seats 411 are arranged opposite to each other. A limiting rod 412 is installed between the opposite side walls of the inner cavity of the concave fixing seat 411. A limiting mounting block 413 is slidably connected to the outer wall of the limiting rod 412. A spring 414 is sleeved on the outer wall of the limiting rod 412, and the spring 414 is located between the inner wall of the concave fixing seat 411 and the limiting mounting block 413. The two limiting wheels 42 are rotatably installed between the two limiting mounting blocks.

[0060] The specific working process of the above embodiments is as follows:

[0061] When charging a car at charging station 1, the charging personnel remove the charging gun and press the switch on charging station 1 to turn on the drive motor 36. The drive motor 36 drives the active gear 37 to rotate (the rotation time of the drive motor 36 is fixed each time it is charged, that is, the sliding distance of the two winding wheel assemblies 34 is consistent each time it is charged), which in turn drives the driven gear 35 and the double-ended lead screw 31 to rotate. The double-ended lead screw 31 drives the sliders 32 and the mounting base 33 at both ends to slide in a direction that approaches each other under the limiting action of the limiting slide rail 38, so that the upper and lower winding wheel assemblies 34 gradually approach each other, thereby changing the charging cable 11 from a taut state to a slack state, so that the charging personnel can stretch the charging cable 11 to charge the vehicle.

[0062] During the sliding process of the winding wheel assembly 34 approaching each other, the rotating gear 39 on the outer wall of the rotating shaft 341 meshes with the rack 310 on the outer wall of the limiting slide rail 38, thereby driving the rotating gear 39, the rotating shaft 341 and the winding wheel 343 to rotate, so that the winding wheel 343 can deliver the charging cable 11 outward as the charging cable 11 becomes loose, thereby reducing the resistance of pulling out the charging cable 11.

[0063] After charging is complete, the charging personnel insert the charging gun back into the fixed position and press the switch of the drive motor 36 again, causing the drive motor 36 to reverse and drive the two winding wheel assemblies 34 to slide away from each other, so that the charging cable 11 is taut again, thus putting the charging cable 11 exposed outside the junction box 2 into a taut state, realizing the cable gathering operation of the charging cable 11. When the winding wheel assemblies 34 slide away from each other, the cooperation between the rotating gear 39 on the outer wall of the rotating shaft 341 and the rack 310 can cause the winding wheel 343 to reverse, thereby assisting in the retraction of the charging cable 11.

[0064] When the charging cable 11 is pulled out or retracted, the angle between the charging cable 11 and the winding wheel assembly 34 changes, which can synchronously drive the limit wheel 42 on the limit wheel 42 assembly to move, and drive the limit mounting blocks 413 on both sides to slide, thereby causing the spring 414 to deform and play a buffering role.

[0065] In summary, the automatic cable collection device for charging piles provided by this utility model allows the double-ended lead screw to rotate via a drive motor after the charging pile is fully charged. This causes the two winding wheel assemblies to slide in opposite directions, gradually tauting the charging cables inside the collection box. This pulls the charging cables outside the collection box back into the box for collection and organization, preventing them from being exposed and posing various risks. Furthermore, the winding wheel assemblies taut the charging cables during collection, eliminating the need for rewinding and preventing damage caused by repeated rewinding. The winding wheels also provide assistance during both the pulling out and retraction of the charging cables, reducing resistance.

[0066] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
