Furthermore, the above design can be folded and rolled up for easy storage and portability.

[0004] While the above solution is convenient to carry, the charging cable can be placed anywhere and is not easy to wind up and store, which affects its use.

[0005] Therefore, there is an urgent need to provide a winding structure for electric vehicle charging boxes to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, such as the charging cable being placed randomly, making it inconvenient to wind and store, which affects its use, and to provide a winding structure for the electric vehicle charging box.

[0007] To solve the above-mentioned technical problems, the present invention provides a winding structure for an electric vehicle charging box, including a photovoltaic blanket, a photovoltaic panel disposed on the top surface of the photovoltaic blanket, and a charging cable connected to the photovoltaic panel, wherein a winding assembly is provided on the side of the charging cable;

[0008] The winding assembly includes a storage shell installed on the top edge of the photovoltaic blanket, a rotating rod disposed inside the storage shell, a take-up roller disposed on the side of the rotating rod, and a take-up sleeve movably connected to the outside of the take-up roller.

[0009] A transmission unit is provided between the rotating rod and the winding roller;

[0010] A limit unit is provided between the take-up sleeve and the transmission unit.

[0011] The present invention is further configured such that: one end of the charging cable is equipped with a charging head, and the top surface of the storage shell is provided with a placement groove that is adapted to the size of the charging head.

[0012] The present invention is further configured such that one end of the rotating rod extends through to the outside of the storage shell.

[0013] The present invention is further configured such that: a lead screw is movably connected to the inner wall of the take-up roller, and a sliding sleeve is threadedly connected to the outer side of the lead screw, and the sliding sleeve is movably connected to the inner wall of the take-up sleeve.

[0014] The present invention is further configured such that: the transmission unit includes a driving gear installed at one end of the rotating rod and a driven gear meshing with the side of the driving gear, the driven gear being installed on the outside of the take-up roller;

[0015] The transmission unit also includes a first transmission wheel installed at the other end of the rotating rod and a second transmission wheel movably connected to the outside of the take-up roller, with a transmission belt provided on the outside of the first and second transmission wheels.

[0016] The present invention is further configured such that: a rotating ring is movably connected to the outer side of the rotating rod, and the second transmission wheel is movably connected to the outer side of the rotating ring.

[0017] The present invention is further configured such that: there are multiple sets of the limiting units, and the multiple sets of the limiting units are distributed in a circular array with the center point of the rotating ring as the center;

[0018] The limiting unit includes a movable groove disposed on the side wall of the rotating ring, a push rod movably connected to the inside of the movable groove, a limiting ring installed on the outside of the push rod, and an extrusion member disposed on the side of the limiting ring. One end of the push rod extends through to the inside of the take-up roller.

[0019] The present invention is further configured such that the limiting unit also includes a reset member disposed between the inner wall of the take-up roller and the sliding sleeve.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, through its winding assembly, allows the operator to rotate a rotating rod to drive the drive gear when the charging cable needs to be wound. Since the drive gear meshes with the driven gear, it drives the winding roller to rotate. The rotation of the winding roller synchronously drives the winding sleeve to rotate, winding the charging cable. Simultaneously, under the elastic compression of the reset component, the sliding sleeve is pushed to rotate along the outer side of the lead screw, causing the sliding sleeve to move along the side wall of the winding roller. This allows the charging cable to wind along the length of the outer surface of the winding sleeve during winding. When the sliding sleeve moves to the limiting unit, the elastic compression of the pressing component pushes the push rod, causing one end to abut against the outer surface of the sliding sleeve. Under the action of the first transmission wheel, the second transmission wheel, and the transmission belt, the rotating ring rotates in the opposite direction to the sliding sleeve, causing the sliding sleeve to slide in the opposite direction along the outer side of the lead screw. This allows the charging cable to repeatedly wind back and forth along the outer surface of the winding sleeve, preventing the charging cable from getting tangled in one place and improving the storage effect.

[0029] Please see Figure 1 - Figure 5 A charging box winding structure for electric vehicles includes a photovoltaic blanket 1, a photovoltaic panel 2 disposed on the top surface of the photovoltaic blanket 1, and a charging cable 3 connected to the photovoltaic panel 2. The connection between the charging cable 3 and the photovoltaic panel 2 is provided with a plug. When the charging cable 3 is wound up, the plug can be unplugged for winding. A winding assembly 4 is provided on the side of the charging cable 3. The winding assembly 4 is used to wind up the charging cable 3 for storage.

[0030] The winding assembly 4 includes a storage shell 41 installed on the top edge of the photovoltaic blanket 1, a rotating rod 42 disposed inside the storage shell 41, a take-up roller 43 disposed on the side of the rotating rod 42, and a take-up sleeve 44 movably connected to the outside of the take-up roller 43. Preferably, the take-up sleeve 44 is slidably connected to the side wall of the take-up roller 43.

[0031] A transmission unit 45 is provided between the rotating rod 42 and the winding roller 43;

[0032] A limit unit 46 is provided between the winding sleeve 44 and the transmission unit 45.

[0033] One end of the charging cable 3 is equipped with a charging head 5, and the top surface of the storage shell 41 is provided with a placement slot 411 that is adapted to the size of the charging head 5.

[0034] One end of the rotating rod 42 extends through to the outside of the storage shell 41.

[0035] The inner wall of the take-up roller 43 is movably connected to a lead screw 47, and the outer side of the lead screw 47 is threadedly connected to a sliding sleeve 48. The sliding sleeve 48 is movably connected to the inner wall of the take-up sleeve 44, preferably the sliding sleeve 48 is rotatably connected to the inner wall of the take-up sleeve 44.

[0036] The transmission unit 45 includes a drive gear 451 mounted on one end of the rotating rod 42 and a driven gear 452 meshing with the side of the drive gear 451. The driven gear 452 is mounted on the outside of the take-up roller 43.

[0037] The transmission unit 45 also includes a first transmission wheel 453 installed at the other end of the rotating rod 42 and a second transmission wheel 454 movably connected to the outside of the take-up roller 43. A transmission belt 455 is provided on the outside of the first transmission wheel 453 and the second transmission wheel 454.

[0038] The rotating rod 42 is movably connected to the outer side of the rotating ring 421, and the second transmission wheel 454 is movably connected to the outer side of the rotating ring 421.

[0039] Among them, there are multiple sets of limiting units 46, and the multiple sets of limiting units 46 are distributed in a circular array with the center point of the rotating ring 421 as the center.

[0040] The limiting unit 46 includes a movable groove disposed on the side wall of the rotating ring 421, a push rod 461 movably connected to the inner side of the movable groove, a limiting ring 462 installed on the outer side of the push rod 461, and a pressing member 463 disposed on the side of the limiting ring 462. One end of the push rod 461 extends through to the inner side of the take-up roller 43. Preferably, the pressing member 463 is a compression spring.

[0042] When the charging cable 3 needs to be wound up, the operator rotates the rotating rod 42 to drive the drive gear 451 to rotate. Since the drive gear 451 meshes with the driven gear 452, it drives the winding roller 43 to rotate. When the winding roller 43 rotates, it synchronously drives the winding sleeve 44 to rotate, winding up the charging cable 3. At the same time, under the elastic compression of the reset member 464, it pushes the sliding sleeve 48 to rotate along the outside of the lead screw 47, so that the sliding sleeve 48 drives the winding sleeve 44 to move along the side wall of the winding roller 43, so that the charging cable 3 will move along the winding sleeve 44 during winding. The outer surface is wound along its length, and when the sliding sleeve 48 moves to the limiting unit 46, it will be pushed by the elastic compression of the pressing member 463 to make one end of the push rod 461 abut against the outer surface of the sliding sleeve 48. Thus, under the action of the first transmission wheel 453, the second transmission wheel 454 and the transmission belt 455, the rotating ring 421 and the sliding sleeve 48 will rotate in opposite directions, so that the sliding sleeve 48 slides in the opposite direction along the outside of the lead screw 47, so that the charging cable 3 is wound back and forth along the outer surface of the take-up sleeve 44, avoiding the charging cable 3 from being tangled in one place and improving the storage effect.
