[0029] A cable reel device for an electric flat car, comprising: a car body 1, a gearbox 21, a motor 22 and a drive shaft 23;

[0030] The front of the vehicle body 1 is provided with a mounting cavity 11;

[0031] A drum structure 2 is installed inside the car body 1, and the drum structure 2 includes a first sprocket 24, which is fixedly mounted on the middle section of the drive shaft 23, and a chain 25 is sleeved on the outer side of the first sprocket 24, one end of the chain 25 is sleeved on the outer side of the second sprocket 26, and a bevel gear disk 27 is fixedly connected to both sides of the middle section of the second sprocket 26. A bracket 28 is fixedly installed on the inner wall of the mounting cavity 11, and a rotating sleeve 29 is movably mounted on the inner side of the bracket 28 through a bearing, and a bevel gear ring 210 is fixedly connected to the outer wall of the rotating sleeve 29. By arranging the second sprocket 26 on the inner side of the mounting cavity 11, the surface of the car body 1 is smooth, which can reduce damage. At the same time, a rotatable rotating sleeve 29 is provided in the middle section of the cable, and the rotating sleeve 29 is sleeved on the outer side of the middle section of the cable. Therefore, the rotation of the rotating sleeve 29 drives the bristles on the inside to wipe and clean the surface of the cable to keep the cable clean and tidy, thereby extending the service life of the cable.

[0032] Furthermore, a collecting structure 3 is provided in the vehicle body 1, and the collecting structure 3 includes a mounting groove 33, which is opened at the front end of the bottom of the mounting cavity 11, and a card ball 34 is fixedly installed on the bottom surface of the mounting groove 33. A collecting box 31 is placed on the inner side of the mounting groove 33, and a card groove 32 is opened on the bottom surface of the collecting box 31. The collecting box 31 is installed in the mounting groove 33, and the card ball 34 is stuck in the card groove 32 on the bottom surface of the collecting box 31, so that the collection box 31 can be stably installed on the inner side of the mounting groove 33. The collecting box 31 can be used to receive the debris cleaned from the cable by the reel structure 2 on the lower side, so that the debris can be properly collected and convenient for unified treatment to ensure a clean environment.

[0033] Furthermore, the gearbox 21 and the motor 22 are both fixedly installed inside the vehicle body 1, the output end of the motor 22 is connected to the input end of the gearbox 21, and the output end of the gearbox 21 is connected to the drive shaft 23.

When the second sprocket 26 rotates, it can drive the two sets of bevel gear discs 27 to rotate. Therefore, the cable wound on the middle section of the second sprocket 26 is lengthened or reeled in, and the set of bevel gear discs 27 on the right side is engaged with the bevel gear ring 210. Therefore, when the second sprocket 26 rotates, it can drive the rotating sleeve 29 to rotate through the bevel gear discs 27 and the bevel gear ring 210. The rotating sleeve 29 rotates inside the bracket 28, and the rotating sleeve 29 is arranged on the outside of the middle section of the cable. Therefore, the rotation of the rotating sleeve 29 drives the bristles inside to wipe and clean the surface of the cable, which can keep the cable clean and tidy and extend the service life of the cable.

[0041] The collecting box 31 is installed in the mounting groove 33, and the card ball 34 is stuck in the card groove 32 on the bottom surface of the collecting box 31, so that the collecting box 31 can be stably installed inside the mounting groove 33.
