[0029] Lifting ring 2: Installed on the top of the charging box 1, with the symmetrical part at the top and installed in a threaded manner, to facilitate the lifting of the entire charging device.

[0030] Heat dissipation grille 3: Bolted on the side of the charging box 1, used for heat dissipation to ensure the normal operating temperature of the electrical components in the charging box 1.

[0031] Gun insertion slot 4: set on the charging box 1, used to plug in the charging gun 7, the charging gun 7 needs to be adapted to the gun insertion slot 4.

[0032] Display control screen 5: It is embedded in the charging box 1 and is used to display charging-related information and perform control operations.

[0033] Cable 6: Connected to the charging box 1 through the interface, one end is connected to the charging gun 7 for transmitting electrical energy.

[0034] Charging gun 7: fixedly connected to one end of the cable 6, used to connect the electric vehicle for charging.

[0035] Hollow mounting plate 8: installed at the bottom of the charging box 1, lifting the charging box 1 as a whole, and provided with mounting holes on it for fixing the entire device or connecting it to other supporting structures.

[0036] Power assist component 9: It is arranged at the diagonal position of the charging box 1 and is used to assist in pulling out and recovering the cables 6. It can support up to four cables 6 at the same time.

[0037] Hydraulic rebound hinge 1 91 : fixed to the charging box 1 , hinged to the first folding plate 92 , providing the first folding plate 92 with rotational connection and rebound functions.

[0038] The first folding plate 92 is connected to the charging box 1 through the hydraulic rebound hinge 1 91 and fixes the hydraulic rebound hinge 2 93 itself. It is the first level structure of the secondary folding of the power assist component 9.

[0039] The second hydraulic rebound hinge 93 is fixed on the first folding plate 92 and hinged to the second folding plate 94 to provide the second folding plate 94 with a rotation connection and rebound function.

[0040] The second folding plate 94 is L-shaped and connected to the first folding plate 92 via a second hydraulic rebound hinge 93. It is the second-level structure of the secondary folding of the power assist assembly 9, and a connecting rod 95 is inserted on it for horizontal rotation.

[0041] Connecting rod 95: It is inserted into the second folding plate 94 and rotates horizontally, and rotates the connecting ring buckle 96 up and down to connect the second folding plate 94 and the ring buckle 96.

[0042] Ring buckle 96: connected to the second folding plate 94 through a connecting rod 95, with a sheath 97 installed inside for hanging the cable 6.

[0043] Sheath 97: Installed inside the ring buckle 96, the internal sliding fills the cable 6 to protect the cable 6;

[0044] The working principle is as follows: When charging with the charging gun 7 is required, the charging gun 7 is pulled out from the gun slot 4. During the removal process, since the cable 6 is connected to the charging gun 7, the cable 6 will be pulled out as the charging gun 7 is pulled out. At this time, the power assist assembly 9 begins to function. The hydraulic rebound hinge 1 91 and the hydraulic rebound hinge 2 93 in the power assist assembly 9 will cause the first folding plate 92 and the second folding plate 94 to unfold in sequence as the cable 6 is pulled out. The connecting rod 95 and the buckle 96 on the second folding plate 94 will also adjust their position as the unfolding action occurs, and the sheath 97 inside the buckle 96 slides, allowing the cable 6 to be pulled out smoothly. When charging is completed, insert the charging gun 7 back into the gun slot 4. Under the action of gravity, the cable 6 will naturally droop. At this time, the hydraulic rebound hinge 1 91 and the hydraulic rebound hinge 2 93 of the power assist component 9 will automatically fold and retract the first folding plate 92 and the second folding plate 94, and the connecting rod 95 and the buckle 96 will also return to their initial positions, thereby realizing the automatic recovery of the cable 6 and the automatic folding of the power assist component 9. During the whole process, the charging box 1 provides support and power control for other components, the lifting ring 2 facilitates the lifting of the device, the heat dissipation grille 3 is used for heat dissipation, and the hollow mounting plate 8 lifts the charging box 1 and fixes the device through the mounting hole.

[0045] like Figure 2 As shown, in some embodiments, the symmetrical part of the lifting ring 2 is at the top of the charging box 1, and the lifting ring 2 is installed in a threaded manner; during the installation process, the charging box 1 and its accessories can be accurately placed in the predetermined position through the lifting ring 2 using lifting equipment; when the charging device needs to be maintained or moved, the lifting operation can also be conveniently performed using the lifting ring 2, thereby improving the operability of the device and the convenience of installation and maintenance.

[0046] like Figure 3 As shown, in some embodiments, the charging gun 7 is inserted into the gun slot 4. At the same time, the charging gun 7 needs to be adapted to the gun slot 4. Through specific design and size specifications, it is ensured that the charging gun 7 can be stably inserted therein and achieve correct electrical connection with the charging circuit inside the charging box 1, thereby providing a channel for subsequent power transmission.

[0047] like Figure 2 As shown, in some embodiments, a hollow mounting plate 8 is installed at the bottom of the charging box 1, and the hollow mounting plate 8 lifts the charging box 1 as a whole. The mounting plate 8 is provided with mounting holes; this can prevent the charging box 1 from directly contacting the ground, prevent moisture, accumulated water on the ground, etc. from corroding or damaging the charging box 1, and extend the service life of the charging box 1.

[0048] like Figure 4As shown, in some embodiments, the second folding plate 94 is L-shaped; structurally, the L-shape can better adapt to the pulling and retrieving path of the cable 6. When the cable 6 is pulled out or retracted, the L-shaped second folding plate 94 can provide appropriate support and guidance in different directions, making the movement of the cable 6 smoother.

[0049] like Figure 1 As shown, in some embodiments, the interior of the sheath 97 is slidably filled with the cable 6 to facilitate the storage of the cable 6.

[0050] like Figure 4 As shown, in some embodiments, the hydraulic rebound hinge 1 91 and the hydraulic rebound hinge 2 93 are arranged at opposite positions, and there is no movement interference, so that secondary folding can be performed.

[0051] like Figure 3 As shown, in some embodiments, the power assist component 9 can support up to four cables 6 at the same time, so as to easily pull out and recycle the heavy cables 6 under the action of gravity. Each set of power assist components 9 can perform secondary folding and unfolding operations. After the charging gun 7 is returned to its position, the power assist component 9 can automatically fold and recycle the cable 6, which is convenient and practical.
