[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The principles and features of the present invention are described below in conjunction with the drawings. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] See also Figure 1-7 As shown in the figure, a charging pile provided in this embodiment is shown in FIG. Figure 1-Figure 6 , comprising a shell 1, a first connecting frame 3 for housing a charging device 2 is fixedly installed on the upper left position of both sides of the inner wall of the shell 1, a second connecting frame 5 for housing a roller device Ⅰ 4 is fixedly installed on the upper right position of both sides of the inner wall of the shell 1, a water storage tank 6 for water supply is fixedly installed at a position below the first connecting frame 3 on the front of the inner cavity of the shell 1, a limiting slide rail 8 for connecting a stroke device 7 is fixedly installed at a position below the water storage tank 6 on both sides of the inner wall of the shell 1, and a roller device Ⅰ 4 is fixedly installed on the left side of the inner wall of the shell 1. A double-hole connecting frame 11 of the roller device II 9 and the extrusion device 10, a dividing rod 12 is fixedly installed at a position between the water tank 6 and the double-hole connecting frame 11 on the front side of the inner cavity of the shell 1, a third connecting frame 14 for mounting an adjusting device 13 is provided on the front side of the inner cavity of the shell 1 on the left side of the limiting slide rail 8, a transmission device 16 for mounting an axle seat 15 is fixedly installed at a position near the top on the back side of the inner cavity of the shell 1, an indicating device 17 is fixedly installed on the top of the outer surface of the shell 1, and a chamber 18 corresponding to the adjusting device 13 is provided on the front side of the outer surface of the shell 1.

[0030] See also Figure 13-Figure 15 The travel device 7 includes a central axis 71, and a liquid guide tube 72 is sleeved on the outer surface of the central axis 71, so that when the charging device 2 is in the process of winding up, the dividing rod 12 can separate the charging line 23 and the liquid guide tube 72, thereby facilitating the winding up of the first rotating shaft 21 and the central axis 71.

[0031] See also Figure 7 The charging device 2 includes a first rotating shaft 21 , baffles 22 are fixedly installed on the outer surface of the first rotating shaft 21 at positions on both sides of the middle, and a charging line 23 is wound around the outer surface of the first rotating shaft 21 at a position between the baffles 22 .

[0032] See also Figure 8 The charging cable 23 includes a wire body 231 , and a card slot 232 is provided below the wire body 231 .

[0033] Specifically, see Fig.16 The extrusion device 10 includes an extrusion shaft 101 , second connecting shafts 102 are fixedly installed on both sides of the extrusion shaft 101 , and an extrusion ring 103 is fixedly installed on the outer surface of the extrusion shaft 101 near the middle.

[0034] See also Figure 5-Figure 6 , Figure 8 and Fig.13 The roller device II 9 is sleeved on the top of the double-hole connecting frame 11, and the second connecting shaft 102 is movably sleeved on the bottom of the double-hole connecting frame 11. The liquid guide tube 72 is in contact with the extrusion ring 103, and the liquid guide tube 72 is embedded in the interior of the card slot 232 under the joint extrusion of the roller device II 9 and the extrusion ring 103.

[0035] It can be understood that the liquid guide tube 72 is in contact with the extrusion ring 103, and the liquid guide tube 72 is embedded in the interior of the card slot 232 under the joint extrusion of the roller device II 9 and the extrusion ring 103, so that the liquid guide tube 72 and the card slot 232 form a whole. During the charging process, the card slot 232 will generate a large amount of heat due to its own resistance, and the coolant inside the liquid guide tube 72 can absorb the heat of the card slot 232, thereby playing a role in cooling, avoiding the problem of unexpected situations in the charging operation due to the excessive temperature of the card slot 232 during the charging process, thereby improving the safety performance of the device.

[0036] Specifically, see Figure 2 and Fig.17 The adjusting device 13 includes a gear column 131, which is meshed with the toothed plate 77. A third connecting shaft 132 is fixedly installed at both ends of the gear column 131. The third connecting shaft 132 passes through the housing 1 and extends to the interior of the chamber 18. A handle 133 is fixedly installed at one end of the third connecting shaft 132 at a position inside the chamber 18.

[0037] Specifically, see Fig.18 The transmission device 16 includes a spring shaft 161 , a transmission gear 162 is fixedly sleeved on the outer surface of the spring shaft 161 , and a connecting block 163 is fixedly installed on one side of the outer surface of the transmission gear 162 .

[0038] See also Fig.15 and Fig.18 The bottom of the connecting block 163 is connected to the top of the connecting seat 73 through a traction rope.

[0039] See also Figure 3 and Fig.18 The transmission gear 162 is meshed with the indicating device 17 .

[0040] Specifically, see Figure 4 , Figure 7 , Fig.15 and Fig.18The indicating device 17 includes an indicating plate 171, a second rotating shaft 172 is movably sleeved on one side of the indicating plate 171, a pointer 173 is fixedly mounted on one end of the second rotating shaft 172, a passive gear 174 is fixedly sleeved on the outer surface of the second rotating shaft 172, and the passive gear 174 is meshed with the transmission gear 162.

[0041] When the charging cable 23 is pulled out, the liquid guide tube 72 on the outer surface of the central shaft 71 will be pulled out synchronously, so that the mass of the liquid guide tube 72 wrapped around the outer surface of the central shaft 71 is reduced, and the total weight is reduced. At this time, under the elastic force of the connecting spring 75, the connecting seat 73 moves in the vertical upward direction under the limiting action of the limiting slide rail 8. Since the bottom of the connecting block 163 is connected to the top of the connecting seat 73 by the traction rope, the traction rope at the bottom of the connecting block 163 is relaxed during the movement of the connecting seat 73. The elastic force of the spring shaft 161 will drive the transmission gear 162 to rotate clockwise, and the driven gear 174 is engaged with the transmission gear 162 to drive the second rotating shaft 172 and the pointer 173 to rotate. The remaining length of the charging cable 23 wrapped around the outer surface of the first rotating shaft 21 is prompted by the direction indicated by the pointer 173, so as to avoid the problem that the user still pulls the charging socket 24 hard after the charging cable 23 and the liquid guide tube 72 are completely released, thereby damaging the device, thereby improving the stability of the device.

[0042] During long-term use, the stiffness coefficient of the connecting spring 75 will decrease, and the traction rope between the connecting seat 73 and the connecting block 163 will become loose, resulting in an error in the direction indicated by the pointer 173. At this time, the handle 133 can be manually rotated. Since the gear column 131 is engaged with the toothed plate 77, the relative distance between the stroke device 7 and the ground can be adjusted as a whole, thereby changing the traction force of the catheter 72, and achieving the effect of adjusting the direction indicated by the pointer 173 while the charging cable 23 and the catheter 72 remain stationary, thereby avoiding the problem of inaccurate indication of the pointer 173 after long-term use, and improving the reliability of the device.

[0043] Specifically, see Figure 7 One end of the charging cable 23 is fixedly connected to a charging socket 24 , and one end of the first rotating shaft 21 is fixedly installed with a motor 25 .

[0044] See also Figure 9-11 The charging socket 24 includes a socket body 241 , a charging interface is disposed at the front section of the socket body 241 , and a pressure sensor 242 is disposed at a position near the bottom of the end of the socket body 241 .

[0045] See also Figure 7 and Fig.11 The signal output end of the pressure sensor 242 is connected to the signal input end of the motor 25 through a wireless data connection.

[0046] Specifically, see Figure 5 and Fig.12 The roller device Ⅰ4 includes a rolling main shaft 41, the outer surface of the rolling main shaft 41 is provided with a rolling groove 42, and the first connecting shaft 43 is fixedly installed at both ends of the rolling main shaft 41, and the first connecting shaft 43 is sleeved with the second connecting frame 5.

[0047] See also Figure 7 and Fig.12 The rolling groove 42 contacts the charging cable 23, thereby preventing the charging cable 23 from deviating to both sides during movement.

[0048] See also Figure 5 and Figure 7 The structure of the roller device I4 is exactly the same as that of the roller device II9, and the roller device II9 is ​​also in contact with the charging line 23.

[0049] Specifically, see Figure 13-Figure 15 , connecting seats 73 are fixedly installed at both ends of the central shaft 71, and travel rods 74 are slidably installed on the left and right sides of the connecting seat 73. A connecting spring 75 is clamped on the top of the travel rod 74, and the bottom of the connecting spring 75 is fixedly connected to the connecting seat 73. A bottom plate 76 is fixedly installed on the bottom of the travel rod 74, and a tooth plate 77 is fixedly installed on the top of the bottom plate 76 at a position on the left side of the central shaft 71.

[0050] See also Figure 6 and Fig.13 The connecting seat 73 and the limiting slide rail 8 are slidably installed.

[0051] See also Figure 6 and Fig.15 A cavity is provided inside the central shaft 71 and is connected to the liquid guide tube 72. A connecting hole 78 is provided on the top of the connecting seat 73, and the connecting hole 78 is connected to the inner cavity inside the central shaft 71. The connecting hole 78 is connected to the water tank 6 through a pipeline.

[0052] See also Figure 6-Figure 7 , Fig.11 and Fig.15 The interior of the water tank 6 is injected with cooling oil, and the height of the top of the water tank 6 from the ground is less than 40 centimeters.

[0053] It can be understood that, under the action of gravity, the coolant inside the water tank 6 enters the interior of the liquid guide tube 72 through the pipeline connecting the connecting hole 78 and the water tank 6 and the inner cavity of the connecting hole 78 and the central axis 71. Since the charging port of the vehicle is generally 40 centimeters above the ground, and the height of the top of the water tank 6 from the ground is less than 40 centimeters, when the operator uses the charging pile to charge the vehicle, the height of the charging socket 24 is greater than the height between the water tank 6 and the ground, so that the coolant level inside the end of the liquid guide tube 72 close to the charging socket 24 is lowered, and the coolant is out of contact with the pressure sensor 242. When the vehicle is fully charged, the user pulls out the charging socket 24 and places it on the ground. At this time, the height of the charging socket 24 and the ground is much smaller than the height between the water tank 6 and the ground, so that the coolant inside the water tank 6 fills the end of the water tank 6 close to the pressure sensor 242 under the action of gravity, and exerts a certain pressure on the pressure sensor 242. After sensing the pressure of the coolant, the pressure sensor 242 is connected to the signal input end of the motor 25 through the signal output end of the pressure sensor 242 by wireless data connection, driving the baffle 22 to rotate and winding the charging line 23 around the first rotating shaft 21, thereby realizing the function of automatic winding, avoiding the situation where the charging socket 24 is placed on the ground after use and is crushed by other vehicles, thereby improving the automation of the device.

[0054] The method of use of the present invention is as follows:

[0055] When in use, the user drags out the charging socket 24 and inserts it into the charging port of the car. The charging port of the vehicle is generally 40 cm above the ground, while the height of the top of the water tank 6 from the ground is less than 40 cm. When the operator uses the charging pile to charge the vehicle, the height of the charging socket 24 is greater than the height between the water tank 6 and the ground, so that the coolant level inside the end of the liquid guide tube 72 close to the charging socket 24 is lowered, and the coolant is disconnected from the pressure sensor 242. When the vehicle is fully charged, the user pulls out the charging socket 24 and places it on the ground. At this time, the height of the charging socket 24 from the ground is much less than The height between the water tank 6 and the ground allows the coolant inside the water tank 6 to fill one end of the water tank 6 near the pressure sensor 242 under the action of gravity, and exert a certain pressure on the pressure sensor 242. After sensing the pressure of the coolant, the pressure sensor 242 is connected to the signal input end of the motor 25 through the signal output end of the pressure sensor 242 by wireless data connection, driving the baffle 22 to rotate and winding the charging line 23 around the first rotating shaft 21, thereby realizing the function of automatic winding. When the charging device 2 is in the process of winding, the branching rod 12 can connect the charging line 23 and the liquid guide tube 72 is split, so as to facilitate the winding of the first rotating shaft 21 and the liquid guiding tube 72. The liquid guiding tube 72 contacts with the extrusion ring 103, and is embedded in the interior of the card slot 232 under the joint extrusion of the roller device II 9 and the extrusion ring 103, so that the liquid guiding tube 72 and the card slot 232 form a whole. During the charging process, the card slot 232 will generate a lot of heat due to its own resistance, and the coolant inside the liquid guiding tube 72 can absorb the heat of the card slot 232, thereby playing a role in cooling. When the charging line 23 is pulled out, the liquid guiding tube 72 on the outer surface of the central shaft 71 will be pulled out synchronously, so that the liquid guiding tube 72 wound on the central shaft The mass of the liquid guide tube 72 on the outer surface of the first rotating shaft 21 is reduced, and the total weight is reduced. At this time, under the elastic force of the connecting spring 75, the connecting seat 73 moves in the vertical upward direction under the limiting action of the limiting slide rail 8. Since the bottom of the connecting block 163 is connected to the top of the connecting seat 73 through the traction rope, the traction rope at the bottom of the connecting block 163 is loose during the movement of the connecting seat 73. The elastic force of the spring shaft 161 will drive the transmission gear 162 to rotate clockwise, drive the second rotating shaft 172 and the pointer 173 to rotate, and the direction indicated by the pointer 173 indicates the remaining length of the charging line 23 wound on the outer surface of the first rotating shaft 21. When there is an error in the direction indicated by the pointer 173, by manually rotating the handle 133, the gear column 131 is engaged with the tooth plate 77, so as to adjust the relative distance between the stroke device 7 and the ground as a whole, thereby changing the traction force of the liquid guide tube 72, and achieving the effect of adjusting the direction indicated by the pointer 173 when the charging line 23 and the liquid guide tube 72 remain stationary.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
