[0002] Lithium-ion batteries, also known as lithium-ion power batteries, refer to lithium-ion batteries with a capacity of 3Ah or higher, and are divided into high-capacity and high-power types. High-power lithium-ion batteries are mainly used in hybrid electric vehicles and other applications requiring high-current charging and discharging. Lithium-ion batteries in hybrid electric vehicles and new energy vehicles require charging stations for charging. During use, there is a risk of forgetting to unplug the charging adapter before driving away, which can easily cause the cables used to charge the car's battery at existing charging stations to be broken or even damaged by the car, affecting both the charging station and the vehicle, and impacting charging safety. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing technologies where forgetting to unplug the charging head before driving away can lead to the breaking or even damage of the charging station and the car. Therefore, this utility model proposes a charging battery cable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a rechargeable battery cable, including a cable and a tension spring. The cable is adhered to the inner outer wall of the tension spring. A pair of fixing rings are fixed to the outer walls of both ends of the tension spring, and the cable is inserted into the inside of the fixing rings. Each pair of fixing rings is rotatably connected to a pull rope through a hinge device. The ends of the two pull ropes close to each other are connected by an elastic rubber rope. The outer walls of the two pull ropes are provided with a switch structure, and the switch structure is electrically connected to a power source and an alarm through a wire. The power source is electrically connected to the alarm through a wire.

[0006] Preferably, an upper conductive cylinder and a lower conductive cylinder are fixed to the outer wall of the two pull ropes that are close to each other, and the lower conductive cylinder is inserted into the interior of the upper conductive cylinder. The upper conductive cylinder and the lower conductive cylinder are respectively connected to a power supply and an alarm through wires.

[0007] Preferably, the switch structure includes a dustproof sleeve bonded to the outer wall of both the upper and lower pull ropes, located outside the upper and lower conductive cylinders, and the outer wall of the dustproof sleeve is provided with a through hole for the wire to pass through.

[0008] Preferably, the lower end of the upper conductive cylinder has an inner chamfer to facilitate insertion of the upper conductive cylinder.

[0009] Preferably, the upper end face of the lower conductive cylinder has an outer chamfer to facilitate the insertion of the upper conductive cylinder.

[0010] Preferably, the inner outer wall of the tension spring has a helical groove with a cross-section of a semi-circular diameter the same as that of the cable, and the cable is bonded inside the helical groove.

[0011] Preferably, the hinge device includes a rotating shaft and a hinge ring. The outer wall of the fixed ring is fixedly provided with the hinge ring located on the inner side, and the rotating shaft is rotatably provided inside the hinge ring. The outer wall of the rotating shaft is fixedly connected to a pull rope.

[0012] The present invention discloses a rechargeable battery cable with the following advantages: the power supply can adapt to changes in length due to the car moving away and changes in distance from the charging port during charging by stretching the cable and the spring. Furthermore, the shorter distance during charging will not cause the upper conductive tube to detach from the lower conductive tube. When the charging plug is forgotten at one end of the cable and the vehicle is started and driven away, the stretching of the spring will cause the two pull ropes to stretch to a certain extent, resulting in the upper conductive tube detaching from the lower conductive tube. This allows the alarm to detect the circuit change and issue a warning, reminding the owner and staff to avoid breaking the cable. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5A rechargeable battery cable includes a cable 3 and a tension spring 1. A pair of fixing rings 4 are fixed on the outer wall of each cable, and the cable 3 is inserted into the inside of the fixing rings 4. Each pair of fixing rings 4 is rotatably connected to a pull rope 5 through a hinge device. The ends of the two pull ropes 5 that are close to each other are connected by an elastic rubber rope 12. The outer wall of the two pull ropes 5 is provided with a switch structure, and the switch structure is electrically connected to a power supply 9 and an alarm 10 through a wire. The power supply 9 is electrically connected to the alarm 10 through a wire.

[0021] Reference Figure 1-5 In order to reduce the entry and contamination of the lower conductive cylinder 13 and the upper conductive cylinder 11 by dust and moisture, the upper conductive cylinder 11 and the lower conductive cylinder 13 are respectively fixed on the outer wall of the two pull ropes 5 close to each other, and the lower conductive cylinder 13 is inserted into the upper conductive cylinder 11. The upper conductive cylinder 11 and the lower conductive cylinder 13 are respectively connected to the power supply 9 and the alarm 10 through wires.

[0022] Reference Figure 1-5 In order to make the switch structure disconnect and the alarm 10 sound when the two pull ropes 5 are far apart, the switch structure includes a dustproof sleeve 2 that is glued to the outer wall of both the upper and lower pull ropes 5 and located outside the upper conductive cylinder 11 and the lower conductive cylinder 13, and the outer wall of the dustproof sleeve 2 is provided with a through hole for the wire to pass through.

[0023] Reference Figure 1-5 In order to facilitate the insertion of the lower conductive cylinder 13 into the upper conductive cylinder 11, the lower end of the upper conductive cylinder 11 is provided with an inner chamfer to facilitate the insertion of the upper conductive cylinder 11.

[0024] Reference Figure 1-5 In order to facilitate the insertion of the lower conductive cylinder 13 into the upper conductive cylinder 11, the upper end face of the lower conductive cylinder 13 is provided with an outer chamfer to facilitate the insertion of the upper conductive cylinder 11.

[0025] Reference Figure 1-5 In order to enhance the stability of the connection between the cable 3 and the tension spring 1, a spiral groove 8 with a cross-section and a diameter the same as that of the cable 3 is opened on the inner outer wall of the tension spring 1, and the cable 3 is bonded in the spiral groove 8.

[0026] Reference Figure 1-5 To reduce wear on the pull rope 5, the hinge device includes a rotating shaft 7 and a hinge ring 6. The outer wall of the fixed ring 4 is fixedly provided with the hinge ring 6 located on the inner side, and the rotating shaft 7 is rotatably provided inside the hinge ring 6. The outer wall of the rotating shaft 7 is fixedly connected to the pull rope 5.

[0027] Working principle: The cable 3 drives the tension spring 1 to stretch to adapt to the length change due to the car moving away. The tension spring 1 stretches the two pull ropes 5 away from the measuring point, which in turn stretches the elastic rubber rope 12. After stretching to a certain extent, the upper conductive cylinder 11 separates from the lower conductive cylinder 13, so that the alarm 10 detects the circuit change and issues a warning to remind the car owner and staff.

[0028] This power supply can adapt to changes in length due to the car moving away and changes in distance from the charging port during charging by stretching the tension spring 1 via the cable 3. Furthermore, the shorter distance during charging will not cause the upper conductive cylinder 11 to detach from the lower conductive cylinder 13. If the vehicle is started and driven away without unplugging one end of the cable 3, the stretching of the tension spring 1 will cause the two pull ropes 5 to stretch the elastic rubber rope 12 to a certain extent, causing the upper conductive cylinder 11 to detach from the lower conductive cylinder 13. This allows the alarm 10 to detect the circuit change and issue a warning, alerting the owner and staff to avoid breaking the cable 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
