[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 , including a wrapping layer 1, which is one of polyester fiber fabric, nylon fabric and cotton canvas fabric. The wrapping layer 1 uses polyester fiber fabric, nylon fabric or cotton canvas fabric as its material, and an interwoven metal mesh layer 2 can be interspersed inside it. The polyester fiber fabric, nylon fabric or cotton canvas fabric is strong and can increase the service life to a certain extent.

[0021] The interior of the wrapping layer 1 is wrapped with a metal mesh layer 2. During production, the warp and weft of the metal mesh layer 2 are respectively interspersed with the warp and weft of the wrapping layer 1. Finally, spot welding is performed at the intersection of the warp and weft of the metal mesh layer 2 to fix the warp and weft of the metal mesh layer 2. The metal mesh layer 2 is made of a metal material with strong toughness and can be easily bent. Therefore, under the action of the metal mesh layer 2, the wrapping layer 1 is shaped. On the other hand, by setting the metal mesh layer 2, a certain electrostatic shielding effect can be provided to the power cord, thereby improving the power charging efficiency.

[0022] A rubber pad layer 3 is provided on one side of the wrapping layer 1. The rubber layer 3 has certain anti-slip properties. As the part in contact with the charger power cord, it has excellent anti-slip properties, which can reduce the outer sheath from sliding on the surface of the charger power cord when the charger power cord is installed.

[0023] A wear-resistant layer 4 is provided on the other side of the wrapping layer 1. The wear-resistant layer 4 is made of one of polyester, ethylene / vinyl acetate copolymer, TPR and polyurea. The wear-resistant layer 4 is made of polyester, ethylene / vinyl acetate copolymer, TPR or polyurea, and has excellent wear-resistant properties. As the outermost layer of the power cord outer sheath, it can play a certain protective role on the power cord.

[0024] Heat dissipation holes 5 are provided on the wrapping layer 1, the rubber cushion layer 3 and the wear-resistant layer 4. The gaps in the heat dissipation holes 5 correspond to the gaps in the metal mesh layer 2. By providing the heat dissipation holes 5, the charger power cord can be fully exposed to the air, thereby increasing the heat dissipation effect.

[0025] A binding strip 6 is fixed to one side of the rubber pad 3. There are at least three binding strips 6, and the binding strips 6 are equidistant from each other. The three binding strips 6 are respectively arranged at both ends and the center of the outer sheath, so that comprehensive binding can be achieved. The corresponding number of binding strips 6 can be added according to the size of the outer sheath. There is no specific restriction on the material of the binding strips 6, and flexible materials can be used.

[0026] The binding cloth strip 6 is provided with a Velcro sub-sticker 7, and the other side of the binding cloth strip 6 is provided with a Velcro mother sticker 8. The length of the Velcro mother sticker 8 is greater than the length of the Velcro sub-sticker 7. The outer sheath is installed by fitting the Velcro sub-sticker 7 onto the Velcro mother sticker 8.

[0027] When the utility model is in use, the power cord outer sheath is first installed on the charger power cord, the rubber cushion layer 3 is facing one side of the power cord, and then curled. After curling tightly, a plurality of binding strips 6 are wrapped around the outermost layer of the wear-resistant layer 4, and finally fixed with Velcro sub-stickers 7 and Velcro mother stickers 8. After the charger of the electric bicycle is connected to the power supply and the electric bicycle, the user adjusts the power cord outer sheath according to the sagging of the charger power cord, and can bend the power cord outer sheath into a suitable shape to prevent the power cord from falling to the ground.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
