Description

Technical Field

[0001] This utility model belongs to the field of cable winding and unwinding technology, specifically relating to an automatic cable winding and unwinding and anti-crushing management device for charging piles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, charging piles, as core supporting facilities, have received widespread attention for their convenience and safety. Charging cables for charging piles are usually quite long and need to be wound up and stored after use to prevent them from being scattered on the ground and subjected to being run over or dragged by vehicles, while also ensuring the safety of passage through the site. To this end, various automatic cable winding and unwinding devices have emerged in the industry. These devices use motor-driven winding rollers, guide wheel groups, and other structures to achieve automatic cable winding. Some devices have also been optimized with features such as uniform winding, heat dissipation, and anti-crushing.

[0003] However, existing automatic cable winding devices still have key technical defects. During the cable winding process, there is a lack of a precise limiting structure for the cable winding angle. Since charging pile cables need to be frequently dragged and turned during use, they are prone to self-torsional deformation. Existing devices can only achieve straight winding or position adjustment of the cable, and cannot force the cable to enter the winding roller at the same angle. This causes the twisted cable to be directly wrapped on the winding roller. Under torsional stress for a long time, it will gradually cause the cable sheath to crack, the inner conductor to break or the insulation layer to be damaged. This not only greatly shortens the service life of the cable, but may also cause safety hazards such as leakage and short circuit, affecting the reliability and safety of the charging pile.

[0004] Therefore, in response to the problem that existing automatic cable winding and unwinding devices for charging piles cannot limit the winding angle, resulting in cable twisting, entanglement, and damage, there is an urgent need to design an improved device with cable winding angle limiting function to solve the damage problem caused by cable twisting and improve the safety and durability of charging piles. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic cable winding and anti-crushing management device for charging piles, which can force the cable to be wound to the winding roller at the same angle, effectively avoiding the direct entanglement of the twisted cable, thereby eliminating long-term torsional stress of the cable, preventing outer sheath cracking, inner core breakage and insulation layer damage, extending the service life of the cable, and reducing safety hazards such as leakage and short circuit.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An automatic cable retraction and anti-crushing management device for charging piles includes a charging pile, wherein a cable is installed inside the charging pile, and one end of the cable extends to the outside and is equipped with a charging gun.

[0008] The charging pile has mounting frames fixed on both the left and right sides. A winding roller is rotatably connected between the two mounting frames. The cable is wound around the outside of the winding roller. A first motor is installed in one of the mounting frames. The output end of the first motor passes through the mounting frame and is connected to the end of the winding roller.

[0009] The charging pile is equipped with a guide structure.

[0010] The guide structure includes two limiting blocks fixed inside the charging pile. The two limiting blocks are symmetrically arranged on the left and right sides of the cable. A limiting plate is installed at one end of the two limiting blocks that are close to each other. Limiting grooves are provided on both sides of the cable, and the two limiting blocks and the limiting plate are inserted into the two limiting grooves.

[0011] Multiple ball bearings are installed on the outside of the limiting plate and the limiting block and inside the limiting groove, and the multiple ball bearings are in contact with the inner wall of the limiting groove.

[0012] A fixed frame is fixed inside the charging pile and outside the cable. A cleaning gear is rotatably connected to one side of the fixed frame. A cleaning pad is provided inside the cleaning gear. A second motor is also installed on one side of the fixed frame. A meshing gear is fixed to the output end of the second motor and meshes with the cleaning gear.

[0013] The cleaning pad contains multiple brushes evenly spaced inside.

[0014] A reciprocating thread is rotatably connected inside the charging pile and on one side of the winding roller. A limit rod is fixed inside the charging pile and at the bottom of the reciprocating thread. A reciprocating guide block is slidably connected to the outside of the limit rod, and the reciprocating guide block is threadedly connected to the reciprocating thread. The reciprocating guide block is located on the outside of the cable. A connection structure is installed between the reciprocating thread and the winding roller.

[0015] The connection structure includes two connecting gears, which are respectively fixed to the outside of the winding roller and the reciprocating thread, and the two connecting gears are meshed together.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This utility model, by adding limiting blocks and limiting plates, forces the cable to be wound onto the winding roller at the same angle, effectively preventing the twisted cable from directly entangled. This eliminates long-term torsional stress in the cable, prevents outer sheath cracking, inner core breakage and insulation layer damage, extends the cable's service life, and reduces safety hazards such as leakage and short circuits. At the same time, combined with the anti-crushing design, it further improves the safety and reliability of the charging pile. Attached Figure Description

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-6 As shown, an automatic cable retraction and anti-crushing management device for charging piles includes a charging pile 1, a cable 2 installed inside the charging pile 1, and one end of the cable 2 extending to the outside and equipped with a charging gun 3.

[0028] The charging pile 1 has mounting brackets 4 fixed on both the left and right sides. A winding roller 5 is rotatably connected between the two mounting brackets 4. The cable 2 is wound around the outside of the winding roller 5. A first motor 6 is installed in one of the mounting brackets 4. The output end of the first motor 6 passes through the mounting bracket 4 and is connected to the end of the winding roller 5. After the user fully charges the electric vehicle or other electrical equipment, the first motor 6 is driven, so that the output end of the first motor 6 drives the winding roller 5 to rotate. The cable 2 is wound around the outside of the winding roller 5 through the winding roller 5, thereby realizing the winding of the charging gun 3 and the cable 2 into the charging pile 1, realizing automatic winding and unwinding and avoiding the situation of being crushed.

[0029] A guide structure is installed inside the charging pile 1.

[0030] See attached document Figures 4-5 The guiding structure includes two limiting blocks 7 fixed inside the charging pile 1. The two limiting blocks 7 are symmetrically arranged on the left and right sides of the cable 2. A limiting plate 8 is installed at the end of the two limiting blocks 7 that is close to each other. Limiting grooves 9 are provided on both sides of the cable 2. The two limiting blocks 7 and the limiting plate 8 are inserted into the two limiting grooves 9. When the cable 2 is wound up, the limiting blocks 7 and the limiting plate 8 can restrict the cable 2, so that the cable 2 can only be wound into the charging pile 1 at the same angle. Therefore, if the cable 2 is twisted or twisted, and it is directly wound on the winding roller 5, the cable 2 will be in a twisted state for a long time, which may cause the outer sheath or inner core of the cable 2 to break.

[0031] Multiple balls 18 are installed on the outside of the limiting plate 8 and the limiting block 7 and inside the limiting groove 9. The multiple balls 18 are in contact with the inner wall of the limiting groove 9. By setting the balls 18, when the limiting block 7 and the limiting plate 8 guide and limit the cable 2, the cable 2 can directly contact the balls 18, which reduces the friction between the cable 2 and the limiting block 7 and the limiting plate 8, ensures the winding speed of the cable 2, and avoids damage to the cable 2 inside the limiting groove 9.

[0032] See attached document Figure 6A fixing frame 10 is fixed inside the charging pile 1 and outside the cable 2. A cleaning gear 11 is rotatably connected to one side of the fixing frame 10. A cleaning pad is provided inside the cleaning gear 11. A second motor 13 is also installed on one side of the fixing frame 10. A meshing gear 12 is fixed to the output end of the second motor 13, and the meshing gear 12 is meshed with the cleaning gear 11. When the cable 2 is wound up, the second motor 13 can be driven, so that the output end of the second motor 13 drives the meshing gear 12 to rotate. Through the meshing connection between the meshing gear 12 and the cleaning gear 11, the meshing gear 12 can drive the cable 2 to rotate. The cleaning gear 11 rotates, causing the cleaning pad inside the cleaning gear 11 to contact the cable 2 and clean the surface of the cable 2. Multiple brushes are evenly arranged inside the cleaning pad, allowing the brushes to further clean the surface of the cable 2 and reach into the limiting groove 9 to clean the inside of the limiting groove 9. The user can turn on the charging pile 1 at regular intervals to remove the dust that has been cleaned. The second motor 13, meshing gear 12, and cleaning gear 11 can be located on the outside of the charging pile 1, so that the dust that has been cleaned falls directly onto the outside of the charging pile 1.

[0033] See attached document Figure 3 A reciprocating thread 14 is rotatably connected inside the charging pile 1 and located on one side of the winding roller 5. A limit rod 16 is fixed inside the charging pile 1 and located at the bottom of the reciprocating thread 14. A reciprocating guide block 17 is slidably connected to the outside of the limit rod 16 and is threadedly connected to the reciprocating thread 14. The reciprocating guide block 17 is located on the outside of the cable 2. A connection structure is installed between the reciprocating thread 14 and the winding roller 5. The connection structure includes two connecting gears 15, and the two connecting gears 15 are respectively fixed on the outside of the winding roller 5 and the reciprocating thread 14. The two connecting gears 15 are meshed and connected.

[0034] When the mounting bracket 4 is driven, it can drive the winding roller 5 to rotate, thereby winding the cable 2. When the winding roller 5 rotates, it can be connected by the meshing of two connecting gears 15, so that the connecting gears 15 can drive the reciprocating thread 14 to rotate. It is connected by the thread between the reciprocating thread 14 and the reciprocating guide block 17, and is limited by the limit rod 16, thereby driving the reciprocating guide block 17 to move. When the reciprocating guide block 17 moves to the end of the reciprocating thread 14, the reciprocating guide block 17 can automatically jump into another thread groove of the reciprocating thread 14, thereby moving towards the other end of the reciprocating thread 14, thereby driving the reciprocating guide block 17 to move left and right. Through the movement of the reciprocating guide block 17, the reciprocating guide block 17 drives the cable 2 to reciprocate left and right around the outside of the winding roller 5, thereby avoiding the cable 2 from only being wound in a certain area of ​​the winding roller 5 and causing accumulation.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
