Description

Technical Field

[0001] This utility model relates to the field of charging piles, and in particular to a cable storage mechanism for multi-line charging piles. 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. To prevent the charging gun cables from becoming tangled, a mechanism is needed to store them.

[0003] A search of Chinese patents revealed publication number CN221137673U, which describes a cable storage mechanism for charging piles. The mechanism includes a cable storage box, a charging pile body, a base, and a control panel. The right side of the cable storage box is movably installed on the left side of the charging pile body. This invention utilizes a limit-position cleaning component in conjunction with a drying cleaning component to conveniently clean the cables stored in the cable storage box after use. This solves the problem of existing cable storage mechanisms failing to effectively clean the surface of the cables during storage. Furthermore, some cables may remain on the ground during use, and dust and impurities adhering to the surface of these cables move into the cable storage mechanism during storage. Over long-term use, large clumps of impurities can accumulate on the cables, leading to blockages inside the cable storage mechanism and affecting its storage efficiency, thus reducing its overall effectiveness.

[0004] Existing cable storage mechanisms are inconvenient for cable storage. Generally, cable storage mechanisms use a winding drum to store cables. When storing cables, it is necessary to manually wind the cables onto the winding drum, which is a cumbersome process, increases workload, reduces practicality, and is inconvenient to use. Furthermore, when using the cable, it is necessary to remove it from the winding drum, which is also troublesome. In order to solve the above problems, we propose a cable storage mechanism for multi-line charging piles. Utility Model Content

[0005] The purpose of this utility model is to provide a cable storage mechanism for multi-line charging piles, which has the advantage of being easy to store.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable storage mechanism for a multi-line charging pile, comprising a housing, a winding drum rotatably sleeved on the inner wall of the housing, an anti-reverse mechanism provided between the winding drum and the surface of the housing, a conductive ring fixedly sleeved on the other end of the winding drum, the outer ring of the conductive ring being fixedly sleeved on the inner wall of the housing and electrically connected to the charging pile, an adjusting shaft rotatably sleeved on the inner wall of the winding drum, a coil spring provided between the surface of the adjusting shaft and the inner wall of the winding drum, a cable fixedly sleeved on the inner wall of the winding drum, the other end of the cable being electrically connected to the inner ring of the conductive ring, and the other end of the cable extending to the outside of the housing and electrically connected to a charging gun.

[0007] By adopting the above technical solution, during storage, rotating the rotating head causes the screw to disengage the ratchet block from the ratchet wheel. The winding drum rotates under the action of the coil spring, and the winding drum rotates to wind up the cable. After winding, the charging gun can be inserted into the charging pile, thereby achieving the purpose of easy storage, reducing workload, improving practicality, and making it convenient to use.

[0008] The present invention is further configured such that: the anti-reverse mechanism includes a fixed block, the fixed block is sleeved with the surface rotating rod of the take-up drum, the fixed block is rotatably sleeved with the adjusting shaft, and the fixed block is bolted to the surface of the outer shell; a screw is threadedly connected to the inner wall of the fixed block; a fixed cylinder is rotatably connected to the bottom of the screw; the fixed cylinder is slidably connected to the inner wall of the fixed block; a telescopic rod is slidably sleeved on the inner wall of the fixed cylinder; a spring is provided between the telescopic rod and the inner wall of the fixed cylinder; a ratchet block is bolted to the bottom of the telescopic rod; a ratchet wheel is provided at the bottom of the ratchet block; and the axis of the ratchet wheel is fixedly sleeved with the surface of the take-up drum.

[0009] By adopting the above technical solution, when the cable is pulled out, the ratchet block engages with the ratchet under the action of the spring to prevent the winding drum from rotating in the opposite direction, thereby preventing the cable from retracting, facilitating charging, and improving practicality. By loosening the fixing nut and rotating the adjusting shaft, the torque of the coil spring can be adjusted, which improves the service life and stability.

[0010] The present invention is further configured such that an adjusting head is bolted to one end of the adjusting shaft.

[0011] By adopting the above technical solution, the adjustment head is set up to facilitate the rotation of the adjustment shaft.

[0012] The present invention is further configured such that a fixing nut is threaded onto the surface of the adjusting shaft.

[0013] By adopting the above technical solution, the adjusting shaft is fixed by setting a fixing nut, thereby improving stability.

[0014] The present invention is further configured such that: a slider is bolted to the surface of both the fixed cylinder and the ratchet block, and a groove is slidably connected to the surface of the slider, and the groove is formed on the inner wall of the fixed block.

[0015] By adopting the above technical solution, the fixed cylinder and ratchet block are prevented from shifting by setting sliders and grooves, thereby improving stability.

[0016] The present invention is further configured such that a rotating head is bolted to the top of the screw.

[0017] By adopting the above technical solution, a rotating head is provided to facilitate the rotation of the screw.

[0018] The present invention is further configured such that a guide wheel is rotatably connected to the inner wall of the outer shell.

[0019] By adopting the above technical solution and setting guide wheels, the friction between the cable and the outer casing is reduced, thereby improving the service life.

[0020] The present invention is further configured such that a mounting plate is bolted to the surface of the outer shell.

[0021] By adopting the above technical solution and setting up an installation plate, installation and fixation are facilitated.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model achieves the purpose of easy storage by rotating the rotating head during storage, causing the screw to drive the ratchet block to disengage from the ratchet wheel, and the winding drum to rotate the rod under the action of the coil spring. The winding drum rotates to wind up the cable. After winding, the charging gun can be inserted into the charging pile, thereby achieving the purpose of easy storage, reducing workload, improving practicality, and making it convenient to use.

[0024] 2. This utility model prevents the rewind drum from rotating in the opposite direction when the cable is pulled out, by having the ratchet block engage with the ratchet under the action of the spring, thereby preventing the cable from retracting, facilitating charging, and improving practicality. By loosening the fixing nut and rotating the adjusting shaft, the torque of the coil spring can be adjusted, which improves the service life and stability. Attached Figure Description

A winding drum 2 is rotatably sleeved on the inner wall of the housing 1. An anti-reverse mechanism 3 is provided between the surface of the winding drum 2 and the surface of the housing 1. A conductive ring 4 is fixedly sleeved on the other end of the winding drum 2, and the outer ring of the conductive ring 4 is fixedly sleeved with the inner wall of the housing 1 and electrically connected to the charging pile. An adjusting shaft 5 is rotatably sleeved on the inner wall of the winding drum 2. A coil spring 6 is provided between the surface of the adjusting shaft 5 and the inner wall of the winding drum 2. There is a cable 7, and the other end of the cable 7 is electrically connected to the inner ring of the conductive ring 4. The other end of the cable 7 extends to the outside of the outer shell 1 and is electrically connected to the charging gun 8. When storing, rotating the rotating head 20 causes the screw 10 to drive the ratchet block 14 to disengage from the ratchet 15. The winding drum 2 rotates under the action of the coil spring 6. The winding drum 2 rotates to wind up the cable 7. After winding, the charging gun 8 can be inserted into the charging pile. This achieves the purpose of easy storage, reduces workload, improves practicality, and is convenient to use.

[0035] refer to Figure 1 and Figure 2 The surface of the adjusting shaft 5 is threaded with a fixing nut 17. By setting the fixing nut 17, the adjusting shaft 5 is fixed and the stability is improved.

[0036] refer to Figure 1 , Figure 2 and Figure 5 A rotating head 20 is bolted to the top of the screw 10, which facilitates the rotation of the screw 10.

[0037] refer to Figure 1 and Figure 3 The inner wall of the outer casing 1 is rotatably connected to a guide wheel 21. By setting the guide wheel 21, the friction between the cable 7 and the outer casing 1 is reduced, thereby improving the service life.

[0038] Example 2:

[0039] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The anti-reverse mechanism 3 includes a fixed block 9, which is sleeved with the rotating rod on the surface of the take-up drum 2, and is also rotatably sleeved with the adjusting shaft 5. The fixed block 9 is also bolted to the surface of the outer casing 1. A screw 10 is threaded onto the inner wall of the fixed block 9, and a fixed cylinder 11 is rotatably connected to the bottom of the screw 10. The fixed cylinder 11 is slidably connected to the inner wall of the fixed block 9. A telescopic rod 12 is slidably sleeved onto the inner wall of the fixed cylinder 11. A spring 13 is provided between the telescopic rod 12 and the inner wall of the fixed cylinder 11. A ratchet block 14 is bolted to the bottom of the telescopic rod 12, and a ratchet wheel 15 is provided at the bottom of the ratchet block 14. The axis of the ratchet wheel 15 is fixedly sleeved onto the surface of the take-up drum 2. When the cable 7 is pulled out, the ratchet block 14 engages with the ratchet wheel 15 under the action of the spring 13 to prevent the winding drum 2 from rotating in the opposite direction, thereby preventing the cable 7 from retracting, facilitating charging, and improving practicality. By loosening the fixing nut 17 and rotating the adjusting shaft 5, the torque of the coil spring 6 can be adjusted, improving service life and stability.

[0040] refer to Figure 1 and Figure 2 An adjusting head 16 is bolted to one end of the adjusting shaft 5, which facilitates the rotation of the adjusting shaft 5.

By setting the slider 18 and the groove 19, the fixed cylinder 11 and the ratchet block 14 are prevented from shifting, thus improving stability.

[0042] refer to Figure 1 and Figure 2 A mounting plate 22 is bolted to the surface of the outer casing 1, which facilitates installation and fixation.

[0043] Brief description of usage: When using the cable, remove the charging gun 8 from the charging station and pull the cable 7. The movement of the cable 7 causes the winding drum 2 to rotate, which in turn tightens the coil spring 6. During the pulling of the cable 7, the ratchet block 14, under the action of the spring 13, continuously engages with the ratchet wheel 15 to prevent the winding drum 2 from reversing, thus preventing the cable 7 from retracting. After pulling the cable 7 to the required length, charging begins. After charging is complete, rotate the rotating head 20. The rotation of the rotating head 20 drives the screw 10 to rotate. The moving fixed cylinder 11 causes the telescopic rod 12 to disengage the ratchet block 14 from the ratchet 15. The winding drum 2 reverses under the action of the coil spring 6 and winds up the cable 7. After winding, the charging gun 8 is inserted into the charging pile for easy storage. By loosening the fixing nut 17 and rotating the adjusting head 16, the adjusting head 16 rotates the adjusting shaft 5. The rotation of the adjusting shaft 5 changes the torque of the coil spring 6, thereby adjusting the torque of the coil spring 6. After adjustment, the fixing nut 17 is tightened to fix it.

[0044] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
