[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0024] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0025] Figure 1 1 is an exploded schematic diagram of a charging pile of a power supply line transfer installation structure provided in an embodiment of the present application; it includes a charging shell 10 and a shell upper cover 20. The back plate inside the charging shell 10 is provided with an inner mounting platform 30 protruding toward the inside of the shell, and the inner mounting platform 30 forms a mounting groove 40 on the back plate of the charging shell 10, see Figure 2 Schematic diagram of the back.

[0026] The mounting groove 40 can be formed by pressing together with the charging shell 10 during the production process, or it can be formed by additional hot melting or welding according to the specific material. The mounting groove 40 is mainly used for external wiring, including a through-groove 41 and a wiring compartment 42 connected to the through-groove 41. The through-groove 41 extends from the bottom of the charging shell 10 to the center of the back panel and connects to the wiring compartment 42. In some embodiments, the wiring direction can be from bottom to top, or introduced from the side, so the mounting groove 40 can be vertically arranged in the direction perpendicular to the ground during design, or horizontally arranged on the side back panel of the charging shell 10.

[0027] In order to improve the space utilization of the inner cavity of the shell, the power supply line 50 and the charging gun line 60 can be stacked and introduced into the wiring compartment 42 and the inside of the shell through the penetration groove 41. In this way, space can be saved as much as possible compared to the parallel arrangement or separate introduction. In addition, in the present application, the power supply line 50 is only arranged in the installation groove 40 outside the shell, and can be connected to the inside after being introduced into the wiring compartment 42 through the penetration groove 41, while the charging gun line 60 needs to be additionally introduced into the shell from the penetration groove 41. In this way, the power supply line 50 can minimize the internal space occupied by the inward penetration and improve the space utilization.

[0028] Figure 3It is a schematic diagram of the structure inside the shell. For the stacked power supply line 50 and the charging gun line 60, because they are structures protruding into the cavity, in order to occupy the internal space as little as possible, the mounting groove 40 can be a T-shaped structure, so the T-shaped inner mounting platform 30 is formed inside the charging shell 10, and the protrusion height of the inner mounting platform 30 (that is, the depth of the mounting groove 40) should not be too high to ensure that the charging gun line 60 will not be squeezed by the shell cover 20 when it is passed through. In some embodiments, in order to achieve better space utilization, the passing groove 41 can be set as a trapezoidal sink, that is, it becomes narrower toward the inside of the shell, and the top width is preferably the width of a single charging gun line 60. The wiring bin 42 can also be designed as a rectangular sink, and its size must ensure that it can accommodate wiring components. Specifically, a number of locking columns can be set inside the shell near the inner mounting platform 30, and corresponding mounting holes are opened on the plate body 81, and the locking screws are used to fasten the installation to prevent the simple snap-on installation from falling off under vibration.

[0029] Figure 4 This is a detailed view of the back of the charging case. Since the power supply line 50 is completely set outside the case, although it will not be easily touched at the back panel, it is necessary to ensure waterproof and other adverse factors. Therefore, in some embodiments, a mounting partition 43 is also provided between the threading groove 41 and the wiring compartment 42, and a threading hole 44 is opened on the mounting partition 43. Figure 4 The power supply line 50 passes through the threading hole 44 into the wiring compartment 42 and is fastened to the mounting partition 43. Specifically, the power supply line 50 can be provided with threads in the section passing through the threading hole 44, and nuts are respectively installed on both sides of the mounting partition 43 and engaged with the threads to fasten. In order to prevent the wiring compartment 42 from being directly exposed, a removable cover plate 45 can also be provided on the wiring compartment 42 for further protection.

[0030] An outer mounting platform 70 protruding in the direction away from the back plate is provided in the penetration groove 41, and the outer mounting platform 70 forms a groove 31 on the inner mounting platform 30 inside the shell. The main function of the outer mounting platform 70 is to introduce the charging gun line 50 from the outside into the shell. Similarly to the above, a threading hole 44 is also provided on the side of the outer mounting platform 70 close to the bottom of the shell, and the threading hole 44 is connected to the internal groove 31 and is fastened by a nut thread engagement. The charging gun line 60 enters the groove 31 through the threading hole 44, and is connected to the electrical installation area along the inner mounting platform 30 in the shell, and can be specifically installed on an adapter board or other circuit board. In this design, it is necessary to ensure that the outward protrusion height of the outer mounting platform 70 is less than the depth of the penetration groove 41, so that the power supply line 50 can also be introduced into the wiring compartment 42 through the top surface of the outer mounting platform 70 and the penetration groove 41. Inside the shell, a side of the groove 31 close to the electrical installation area is an inclined surface, and the charging gun wire 60 entering the shell through the threading hole 44 is routed along the inclined surface of the groove 31 until it is connected to the electrical installation area.

[0031] In summary, this application adopts the internal and external stacking wiring method, the power supply line is wired in the wiring compartment protruding outside the shell, and the charging gun line is passed through the outer mounting platform set in the penetration groove to the inside of the shell, and then fixed and routed along the inner mounting platform until it is connected to the wiring terminal. This method can optimize the space utilization of the charging pile shell from the perspective of the charging pile shell structure and line arrangement structure.
