[0020] In summary:

[0021] In the utility model, by setting the above-mentioned structure, personnel can adjust the density of the rubber sleeve on the charging cable according to the contact area between the rubber sleeve on the charging cable and the ground. The more the contact area with the ground or the more frequent the contact, the tighter the rubber sleeve is arranged on the charging cable.

[0026] Reference Figure 1-3 As shown, the utility model provides a technical solution: a wear-resistant automotive cable, comprising a charging cable 1, one end of the charging cable 1 is fixedly connected to a plug 2, and the other end of the charging cable 1 is fixedly connected to a charging gun 3.

[0027] The following is a detailed description of its overall specific settings and functions.

[0028] In this embodiment: the outer surface of the charging cable 1 is uniformly and slidably covered with a plurality of rubber sleeves 4. The personnel can adjust the density of the rubber sleeves 4 on the charging cable 1 according to the contact area between the charging cable 1 and the ground. The more contact area with the ground or the more frequent the contact, the denser the rubber sleeves 4 are on the charging cable 1. The rubber sleeves 4 can effectively avoid direct friction between the charging cable 1 and the ground, thereby improving the wear resistance of the charging cable 1 during use.

[0029] A plurality of balls 7 are evenly embedded in the rubber sleeve 4, and the balls 7 are made of metal. By providing the balls 7, during the process of pulling the charging cable 1, the balls 7 will move relative to the ground, thereby reducing the direct friction between the rubber sleeve 4 and the ground, and the balls 7 made of metal are not easily worn, further improving the wear resistance of the charging cable 1 during the pulling process.

[0030] Specifically, the arc surface of the rubber sleeve 4 is evenly provided with a plurality of rectangular holes 5. By providing the rectangular holes 5 provided on the rubber sleeve 4, the covering area of ​​the charging cable 1 by the rubber sleeve 4 is reduced, thereby facilitating the heat dissipation of the charging cable 1 during the charging process. The inner side of the rubber sleeve 4 is evenly fixedly connected with a plurality of longitudinal bars 6, and the cross section of the longitudinal bar 6 is an isosceles triangle. The longitudinal bars 6 with a triangular prism structure are provided to reduce the contact area of ​​the rubber sleeve 4 installed on the surface of the charging cable 1, which is also for facilitating the normal heat dissipation of the charging cable 1.

[0031] Both ends of the rubber sleeve 4 are fixedly connected with a plurality of spring pieces 8. By arranging the spring pieces 8 to press on the outside of the charging cable 1, the resistance in the process of moving the rubber sleeve 4 is increased, and the rubber sleeve 4 is prevented from sliding on the surface of the charging cable 1.

[0032] The side of the spring sheet 8 facing the charging cable 1 is a convex structure. The convex side of the spring sheet 8 faces the charging cable 1, further increasing the resistance in the process of moving the rubber sleeve 4. The surface of the spring sheet 8 close to the charging cable 1 is evenly provided with a plurality of stripe grooves 9. By providing the stripe grooves 9 provided on the surface of the spring sheet 8, the resistance of the rubber sleeve 4 in the process of moving the surface position of the charging cable 1 is further increased, and the protective effect of the rubber sleeve 4 on the protective position of the charging cable 1 is improved.

[0033] Working principle: personnel can adjust the density of the rubber sleeve 4 on the charging cable 1 according to the contact area between the charging cable 1 and the ground according to the rubber sleeve 4 on the charging cable 1. The more the contact area with the ground or the more frequent the contact, the tighter the rubber sleeve 4 is arranged on the charging cable 1. The rubber sleeve 4 can effectively avoid direct friction between the charging cable 1 and the ground, thereby improving the wear resistance of the charging cable 1 during use. By providing a rectangular hole 5 opened on the rubber sleeve 4, the covering area of ​​the rubber sleeve 4 on the charging cable 1 is reduced, thereby facilitating the heat dissipation work of the charging cable 1 during charging, avoiding the situation where the charging power is too large during charging and the charging cable 1 is not easy to dissipate heat. The longitudinal bars 6 with a triangular prism structure are provided to reduce the contact area of ​​the rubber sleeve 4 installed on the surface of the charging cable 1. It is also for the purpose of facilitating the normal heat dissipation of the charging cable 1. By providing a ball 7, when the charging cable 1 is pulled, the ball 7 will contact the ground. Relative movement occurs between the rubber sleeve 4 and the ground, thereby reducing the direct friction between the rubber sleeve 4 and the ground, and the metal ball 7 is not easy to wear, which further improves the wear resistance of the charging cable 1 during the pulling process. By arranging the spring sheet 8 to squeeze the outside of the charging cable 1, and the convex side of the spring sheet 8 faces the charging cable 1, the resistance in the process of moving the rubber sleeve 4 is increased, and the rubber sleeve 4 is prevented from sliding easily on the surface of the charging cable 1, and the stability of the use of the rubber sleeve 4 after the movement is improved. By arranging the striped groove 9 opened on the surface of the spring sheet 8, the resistance of the rubber sleeve 4 in the process of moving the surface position of the charging cable 1 is further increased, and the protective effect of the rubber sleeve 4 on the protective position of the charging cable 1 is improved. By arranging the above structure, the direct contact between the charging cable 1 and the ground during the dragging process on the ground is avoided, the wear resistance of the charging cable 1 during the movement of the charging cable 1 during the charging process of the car is facilitated, and the service life of the car charging cable 1 is extended to a certain extent.
