[0002] With the rapid development of electric vehicles, charging anxiety is becoming increasingly prominent. Currently, there are three main solutions to the charging problem: 1. Charging with charging piles, the most widely used solution; 2. Battery swapping systems, which solve the problem of charging time for users, but at the same time, high station costs and poor battery replacement quality make this solution difficult to implement; 3. Wireless charging, but wireless charging technology has the disadvantage of low transmission power, which cannot meet the growing charging demand. Charging / battery swapping stations, as important supporting infrastructure for the development of electric vehicles, have important social and economic benefits.

[0003] As the power input source for new energy vehicles, the ease of use of the charging cable directly impacts the user's charging experience. On existing charging piles, the cable, a crucial power output source, varies in length and weight to meet the charging needs of different vehicles. After charging, the cable faces two situations: First, it can be simply thrown on the ground; second, the cable tip can be fixed to the charging pile socket. Improper handling can lead to the cable being crushed or abraded against the ground. High-power charging cables are also bulky, making them difficult and inconvenient for those with less strength.

[0031] The present invention is described in further detail below with reference to the accompanying drawings:

[0032] like Figure 1 As shown, the present invention provides a constant force gun line management device for a charging pile, comprising an active swing arm assembly 1, a driven swing arm assembly 2, a fixing clamp 3 and a base 4. In this embodiment, the constant force gun line management device comprises two sets of active swing arm assemblies 1, driven swing arm assemblies 2, a fixing clamp 3 and a base 4. The two bases 4 are arranged on both sides of the top of the charging pile, distributed left and right, as shown in FIG. Figure 3 As shown, one of the bases is located at the upper end of charging pile A, and the other is located at the upper end of charging pile B, and is the second base. When a person stands directly in front of the charging pile, the side of the first base facing away from the second base is in the same horizontal plane as the left side wall of the charging pile; the side of the second base facing away from the first base is in the same horizontal plane as the right side wall of the charging pile. The lower end of the base 4 is provided with multiple connectors 41, specifically fixing screws, which are fixedly connected to the charging pile. It should be noted that the fixed connection here is a detachable connection.

[0033] The active swing arm assembly 1 and the driven swing arm assembly 2 are arranged on the upper end of the base 4, as shown in FIG. Figure 4 As shown, one side of the active swing arm assembly 1 is movably connected to the base 4 through a connecting unit, and the other end is movably connected to the driven swing arm assembly 2 through a hydraulic transmission device 5. A protective shell 11 is provided on the side of the active swing arm assembly 1 close to the connecting unit, and the protective shell 11 rotates in the same direction as the active swing arm assembly 1. The driven swing arm assembly 2 is provided on the side of the active swing arm assembly 1 away from the protective shell 11. The driven swing arm assembly 2 is connected to the active swing arm assembly 1 through a rotating shaft, as shown in FIG. Figure 6As shown, a hydraulic transmission device 5 is disposed between the opposing sides of the active swing arm assembly 1 and the passive swing arm assembly 2. One end of the hydraulic transmission device 5 is fixedly connected to the active swing arm assembly 1, and the other end is movably connected to the passive swing arm assembly 2. The fixed connection here is welded, threaded, or other means, which can be adjusted accordingly according to actual conditions. The hydraulic transmission device 5 can adjust the angle between the active swing arm assembly 1 and the passive swing arm assembly 2 within a range of 0-180°.

[0034] The connecting unit includes a rotating shaft 6, a fixing member 7, a first washer 8 and a second washer 9. Figure 5 As shown, the fixing part 7 is arranged inside the base 4, the rotating shaft 6 passes through the active swing arm assembly 1 from top to bottom and is hinged to the fixing part 7, the first washer 8 is sleeved on the upper end of the rotating shaft 6 and clamped with the protective shell 11, and the second washer 9 is sleeved on the lower end of the rotating shaft 6 and clamped with the protective shell 11.

[0035] The fixing clamp 3 is arranged at the lower end of the driven swing arm assembly 2 away from the active swing arm assembly 1. The fixing clamp 3 is fixedly connected to the driven swing arm assembly 2, specifically by welding. At the same time, a through hole 31 is provided on the fixing clamp 3. The shape of the through hole 31 is adapted to the gun line. Figure 1 As shown, one end of the gun line is fixedly connected to the charging pile, and the other end passes through the through hole 31 and can be connected to the charging base of the new energy vehicle or the charging pile. After the gun line passes through the through hole 31, it will be suspended to prevent the gun line from touching the ground, avoiding the risk of gun line wear and gun head being compressed and damaged.

[0036] like Figure 2 As shown, the constant force gun line management device is installed on the top of the charging pile, and the charging gun passes through the through hole 31. The weight of the gun line is carried by the constant force gun line management device. The customer only needs to pull the gun line by hand. The gun line is fixed on the driven swing arm assembly 2, wherein the driven swing arm assembly 2 and the active swing arm assembly 1 are connected together through a rotating shaft, wherein one end of the hydraulic transmission device 5 is installed on the driven swing arm assembly 2, and the other end is fixed on the active swing arm assembly 1. The hydraulic transmission device 5 is a constant force hydraulic device. The dragging force of the gun line causes the internal pressure of the hydraulic transmission device to change, thereby causing the hydraulic transmission device 5 to produce a displacement. The driven swing arm assembly 2 and the active swing arm assembly 1 present a certain angle, causing the gun line to produce a certain displacement. When it reaches the appropriate position, the customer can plug in the gun to complete charging; after charging is completed, the customer can pull out the gun and then plug in the gun, or even not plug in the gun. The constant force gun line management device uses the weight of the gun line itself to cause the internal pressure of the hydraulic transmission device 5 to change, slowly dragging the gun line back to its original position, so that the gun head will not fall to the ground when the customer does not plug in the gun; thereby improving the customer experience and reducing the effort required for charging.

[0037] For different types of vehicles, the length of the gun line is also different. The present application adjusts the length of the gun line by fixing the clamp 3 to meet the requirements of different vehicles for the gun line, thereby improving the utilization rate of the gun line length and being compatible with more types of vehicles.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
