[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Figure 1 : is a schematic diagram of the structure of an automatic charging device according to an embodiment of the utility model, such as Figure 1 As shown, the automatic charging device includes: a charging gun 10, an automatic charging system 20, a liquid cooling system and a gun line management device 40.

[0030] Among them, the charging gun 10 includes a gun line 101 and a gun head 102; the automatic charging system 20 is used to control the charging gun 10 to automatically insert the gun and charge; the liquid cooling system includes a cold source 301 and a cooling pipe 302, the cold source 301 is used to provide coolant, and the coolant cools the gun line 101 and the gun head 102 of the charging gun through the cooling pipe 302 and then flows back to the cold source 301; the gun line management device 40 is used to provide a wire fulcrum for the gun line and the cooling pipe 302.

[0031] Specifically, Figure 1As shown, the charging gun 10 includes: a gun line 101, a gun head 102, an automatic mechanical arm 103 and a visual positioning system 104. The gun head 102 has a charging gun needle and a metal conductor inside, which is positioned by the visual positioning system 104. The automatic charging system 20 controls the movement of the automatic mechanical arm 103 according to the positioning result to realize automatic insertion and automatic charging of the gun head 102. In order to improve the charging power, the gun line 101 is a liquid-cooled gun line. The cooling pipe 301 of the liquid cooling system cools the gun line 101 and the gun head 102 through the coolant provided by the cold source 301. The liquid cooling system is a heat dissipation cold source. The coolant is driven to flow through the gun line 101 and the gun head 102 through power elements such as pumps, providing a cooling function for the gun line 101 and the gun head 102 during charging, thereby increasing the charging current and the charging power. However, if the gun line 101 is bent, the cooling pipe 301 will also be bent and deformed, resulting in a reduction in the cross-sectional area at the bend, obstruction of the flow of the coolant, or even blockage. To this end, the utility model is provided with a gun line management device 40, which is a fixed or movable structure. The device can set a suitable wire fulcrum for the gun line 101, so that the gun line 101 and the cooling tube 302 have a sufficient bending radius under any charging condition, so that the gun line 101 and the cooling tube 302 can move and bend in an orderly and reasonable manner during the charging action, thereby avoiding the problem of gun line wear and coolant flow obstruction caused by the gun line and the cooling tube dragging on the ground and sharp bending.

[0032] Specifically, the bending process of the cooling tube 302 is as follows: Figure 2-7 , pipeline bending state 1, pipeline bending state 2 and pipeline bending state 3 are three process change examples of the cooling pipe 302 when the gun line 101 is bent (only three state examples in the whole process). During the bending process of the gun line 101, the internal cooling pipe 302 will also be bent, and the cross-sections of the cooling pipe 302 are S1-S2-S3 in sequence, and the cross-sectional area is constantly decreasing (for the same circumference, the circle has the largest area, and the less it is close to the circle, the smaller the area), which causes the flow of the coolant 1012 to be obstructed or even blocked. The automatic charging system using the gun line management device can set appropriate line fulcrums and movement paths for the gun line 101 and the cooling pipe 302, so as to ensure that the gun line 101 has a sufficient bending radius under any charging condition to avoid excessive bending.

[0033] An example of the bending of the gun line 101 during the automatic charging process is as follows Figure 8-13 , posture 1, posture 2, and posture 3 are three typical postures, respectively. In any bending section of any posture, the bending radius R11, R12, R1, R21, R22, R23, R31, R32, R33 of the liquid cooling gun line 101 and any other bending radius can be greater than the minimum bending radius required by the gun line 101, so as to avoid the internal cooling pipe 302 being excessively bent and causing the flow of the coolant 1012 to be blocked.

[0034] Furthermore, in the present invention, the cooling pipe 302 may start from the outlet of the cold source 301 , and after contacting the charging gun needle and the metal conductor inside the gun head along the gun line 101 , return to the inlet of the cold source 301 from inside the gun head.

[0035] In the present invention, the liquid cooling system may further include: a pump, which is disposed in the cooling pipe 302 , and the pump 302 is used to drive the coolant, and can increase the flow rate of the coolant and improve the cooling efficiency.

[0036] In the present invention, the gun line management device 40 may include: a line clamp 401. The line clamp 401 is above the ground by a first set distance.

[0037] Specifically, the wire clamp 301 of the gun wire management device 40 is set at a certain height, that is, the gun wire 101 is suspended and is located above the ground 40 under any charging conditions, and there will be no problem of the gun wire dragging on the ground and causing cable wear.

[0038] In the present invention, the gun line may further include: a wire sheath, the wire sheath covers the outside of the gun line, the wire sheath is the gun line external protection structure, and is used to protect the gun line. A wire sheath may also be provided outside the cooling pipe 302 .

[0039] In summary, according to the automatic charging device of the embodiment of the utility model, a liquid cooling system can provide a cooling function for the gun line and the gun head of the charging gun during charging, thereby increasing the charging current and charging power of the automatic charging device and realizing high-power charging. By setting a gun line management device to provide a suitable wire fulcrum for the gun line, the gun line and the cooling tube have a sufficient bending radius under any charging condition, so that the gun line and the cooling tube can move and bend in an orderly and reasonable manner during the charging action, thereby avoiding the problems of gun line wear and coolant flow obstruction caused by the gun line dragging on the ground and sharp bending.
