Detailed implementation manners

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] Please refer to Figure 1-7 , as shown in the figure, a charging pile provided in this embodiment. Please refer to Figure 1-Figure 6 , which includes a housing 1. On the upper left side of both sides of the inner wall of the housing 1, a first connecting frame 3 for sleeving the charging device 2 is fixedly installed. On the upper right side of both sides of the inner wall of the housing 1, a second connecting frame 5 for sleeving the roller device I 4 is fixedly installed. On the front side of the inner cavity of the housing 1, below the first connecting frame 3, a water storage tank 6 for supplying water is fixedly installed. On both sides of the inner wall of the housing 1, below the water storage tank 6, a limit slide rail 8 for connecting the travel device 7 is fixedly installed. On both sides of the inner wall of the housing 1, on the left side of the water storage tank 6, a double-hole connecting frame 11 for sleeving the roller device II 9 and the extrusion device 10 is fixedly installed. On the front side of the inner cavity of the housing 1, between the water storage tank 6 and the double-hole connecting frame 11, a wire dividing rod 12 is fixedly installed. On the front side of the inner cavity of the housing 1, on the left side of the limit slide rail 8, a third connecting frame 14 for sleeving the adjusting device 13 is provided. On the back side of the inner cavity of the housing 1, near the top, a transmission device 16 for sleeving the shaft seat 15 is fixedly installed. On the top of the outer surface of the housing 1, an indicating device 17 is fixedly installed. On the front side of the outer surface of the housing 1, a chamber 18 corresponding to the adjusting device 13 is provided.

[0030] Please refer to Figure 13-Figure 15 , the travel device 7 includes a central shaft 71. A liquid guide pipe 72 is sleeved on the outer surface of the central shaft 71, so that when the charging device 2 is taking in the wire, the wire dividing rod 12 can split the charging wire 23 and the liquid guide pipe 72, thus facilitating the wire taking-in of the first rotating shaft 21 and the central shaft 71.

[0031] Please refer to Figure 7 , the charging device 2 includes a first rotating shaft 21. On the outer surface of the first rotating shaft 21, on both sides of the middle, baffles 22 are fixedly installed. On the outer surface of the first rotating shaft 21, between the baffles 22, a charging wire 23 is wound.

[0032] Please refer to Figure 8 , the charging wire 23 includes a wire main body 231. Below the wire main body 231, a card slot 232 is provided.

[0033] Specifically, please refer toFigure 16 The squeezing device 10 includes a squeezing shaft 101. Second connecting shafts 102 are fixedly installed on both sides of the squeezing shaft 101. A squeezing ring 103 is fixedly installed on the outer surface of the squeezing shaft 101 near the middle position.

[0034] Please refer to Figure 5-Figure 6 , Figure 8 and Figure 13 , the roller device II 9 is sleeved above the double-hole connecting frame 11. The second connecting shaft 102 is movably sleeved below the double-hole connecting frame 11. The liquid guide pipe 72 is in contact with the squeezing ring 103. And under the combined squeezing of the roller device II 9 and the squeezing ring 103, the liquid guide pipe 72 is embedded into the inside of the card slot 232.

[0035] It can be understood that by the liquid guide pipe 72 being in contact with the squeezing ring 103, and under the combined squeezing of the roller device II 9 and the squeezing ring 103, the liquid guide pipe 72 is embedded into the inside of the card slot 232, making the liquid guide pipe 72 and the card slot 232 form a whole. During the charging process, a large amount of heat will be generated in the card slot 232 due to its own resistance value. And the coolant inside the liquid guide pipe 72 can absorb the heat of the card slot 232, thus playing a role in cooling, avoiding the problem that the charging operation may have accidents due to the too high temperature of the card slot 232 during the charging process, and improving the safety performance of the device.

[0036] Specifically, please refer to Figure 2 and Figure 17 , the adjusting device 13 includes a gear column 131. The gear column 131 is meshed with a toothed plate 77. Third connecting shafts 132 are fixedly installed at both ends of the gear column 131. The third connecting shafts 132 penetrate through the housing 1 and extend into the inside of the chamber 18. A handle 133 is fixedly installed at one end of the third connecting shaft 132 located inside the chamber 18.

[0037] Specifically, please refer to Figure 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. A connecting block 163 is fixedly installed on one side of the outer surface of the transmission gear 162.

[0038] Please refer to Figure 15 and Figure 18 , the bottom of the connecting block 163 is connected to the top of the connecting seat 73 through a traction rope.

[0039] Please refer to Figure 3 and Figure 18 The transmission gear 162 is meshed with the indicating device 17.

[0040] Specifically, please refer to Figure 4 , Figure 7 , Figure 15 and Figure 18, the indicating device 17 includes an indicating disk 171. A second rotating shaft 172 is movably sleeved on one side of the indicating disk 171. One end of the second rotating shaft 172 is fixedly installed with a pointer 173. A driven gear 174 is fixedly sleeved on the outer surface of the second rotating shaft 172. The driven gear 174 meshes with the transmission gear 162.

[0041] When the charging cable 23 is pulled out, the liquid guide pipe 72 on the outer surface of the central shaft 71 will be synchronously pulled out, reducing the mass and total weight of the liquid guide pipe 72 wound around the outer surface of the central shaft 71. At this time, under the elastic force of the connecting spring 75, the connecting seat 73 moves upward along the vertical 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 a traction rope, the traction rope at the bottom of the connecting block 163 is slack during the movement of the connecting seat 73. The elastic force of the spring shaft 161 drives the transmission gear 162 to rotate clockwise. Through the meshing of the driven gear 174 and the transmission gear 162, the second rotating shaft 172 and the pointer 173 are driven to rotate. The remaining length of the charging cable 23 wound around the outer surface of the first rotating shaft 21 is prompted by the direction indicated by the pointer 173, avoiding the problem that the device is damaged when the user still pulls the charging socket 24 forcefully after the charging cable 23 and the liquid guide pipe 72 are completely released, and improving the stability of the device.

[0042] During long-term use, the spring constant of the connecting spring 75 will decrease, and the traction rope between the connecting seat 73 and the connecting block 163 will become slack, 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 meshes with the toothed plate 77, the relative distance between the entire stroke adjusting device 7 and the ground can be adjusted, thereby changing the traction force on the liquid guide pipe 72, achieving the effect of adjusting the direction indicated by the pointer 173 when the charging cable 23 and the liquid guide pipe 72 are stationary, avoiding the problem that the pointer 173 indicates inaccurately after long-term use, and improving the reliability of the device.

[0043] Specifically, please refer to 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] Please refer to Figure 9-Figure 11 , the charging socket 24 includes a socket main body 241. A charging interface is provided at the front section of the socket main body 241, and a pressure sensor 242 is provided at a position near the lower end of the end of the socket main body 241.

[0045] Please refer to Figure 7 and Figure 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 method.

[0046] Specifically, please refer to Figure 5 and Figure 12 , the roller device I 4 includes a rolling main shaft 41. A rolling groove 42 is provided on the outer surface of the rolling main shaft 41. First connecting shafts 43 are fixedly installed at both ends of the rolling main shaft 41, and the first connecting shafts 43 are sleeved with the second connecting frame 5.

[0047] Please refer to Figure 7 and Figure 12 , the rolling groove 42 is in contact with the charging cable 23, so as to prevent the charging cable 23 from shifting to both sides during movement.

[0048] Please refer to Figure 5 and Figure 7 , the structure of the roller device I 4 is exactly the same as that of the roller device II 9, and the roller device II 9 is also in contact with the charging cable 23.

[0049] Specifically, please refer to Figure 13-Figure 15 , connecting seats 73 are fixedly installed at both ends of the central shaft 71. Stroke rods 74 are slidably installed on the left and right sides of the connecting seats 73. Connecting springs 75 are clamped at the tops of the stroke rods 74. The bottoms of the connecting springs 75 are fixedly connected to the connecting seats 73. Bottom plates 76 are fixedly installed at the bottoms of the stroke rods 74. A toothed plate 77 is fixedly installed at a position on the top of the bottom plate 76 to the left of the central shaft 71.

[0050] Please refer to Figure 6 and Figure 13 , the connecting seats 73 are slidably installed with the limit slide rails 8.

[0051] Please refer to Figure 6 and Figure 15 , a cavity is provided inside the central shaft 71 and is communicated with the liquid guide pipe 72. A communication hole 78 is opened at the top of the connecting seat 73, and the communication hole 78 is communicated with the cavity inside the central shaft 71. The communication hole 78 is communicated with the water storage tank 6 through a pipeline.

[0052] Please refer to Figure 6-Figure 7 , Figure 11 and Figure 15 , cooling oil is injected into the water storage tank 6, and the height of the top of the water storage tank 6 from the ground is less than forty centimeters.

[0053] It can be understood that the coolant inside the water storage tank 6, under the action of gravity, enters the inside of the liquid guide pipe 72 through the pipe communicating between the communication hole 78 and the water storage tank 6, the communication hole 78, and the inner cavity of the central shaft 71. Since the charging port of the vehicle is generally forty centimeters above the ground, and the height of the top of the water storage tank 6 from the ground is less than forty centimeters, when the operator uses the charging pile to charge the vehicle, at this time, the height of the charging socket 24 is greater than the height between the water storage tank 6 and the ground, causing the liquid level of the coolant inside the end of the liquid guide pipe 72 close to the charging socket 24 to decrease, and at the same time, the coolant is separated from the pressure sensor 242. When the vehicle finishes charging and the user pulls out the charging socket 24 and places it on the ground, at this time, the height between the charging socket 24 and the ground is much less than the height between the water storage tank 6 and the ground, causing the coolant inside the water storage tank 6 to fill the end close to the pressure sensor 242 inside the water storage tank 6 under the action of gravity and apply a certain pressure to the pressure sensor 242. After the pressure sensor 242 senses the pressure of the coolant, it is connected to the signal input end of the motor 25 through the signal output end of the pressure sensor 242 in a wireless data connection manner, driving the baffle 22 to rotate and winding the charging wire 23 around the first rotating shaft 21, thereby realizing the function of automatic wire collection, avoiding the situation that the charging socket 24 is placed on the ground and being run over by other vehicles after use, and improving the automation of the device.

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

[0055] During use, the user drags out the charging socket 24 and inserts it into the vehicle's charging port. Generally, the vehicle's charging port is 40 centimeters above the ground, while the height of the top of the water storage tank 6 from the ground is less than 40 centimeters. When the operator uses the charging pile to charge the vehicle, at this time, the height of the charging socket 24 is greater than the height between the water storage tank 6 and the ground, causing the liquid level of the coolant inside the end of the liquid guide pipe 72 close to the charging socket 24 to drop, and at the same time, the coolant is separated from the pressure sensor 242. After the vehicle finishes charging, when 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 storage tank 6 and the ground, causing the coolant inside the water storage tank 6 to fill the end near the pressure sensor 242 inside the water storage tank 6 under the action of gravity and exert a certain pressure on the pressure sensor 242. After the pressure sensor 242 senses the pressure of the coolant, it is connected to the signal input end of the motor 25 through the signal output end of the pressure sensor 242 in a wireless data connection manner, driving the baffle 22 to rotate and winding the charging wire 23 around the first rotating shaft 21, thus realizing the function of automatic wire winding. When the charging device 2 is winding the wire, the wire dividing rod 12 can separate the charging wire 23 and the liquid guide pipe 72, facilitating the wire winding of the first rotating shaft 21 and the liquid guide pipe 72. The liquid guide pipe 72 is in contact with the extrusion ring 103, and under the combined extrusion of the roller device II 9 and the extrusion ring 103, the liquid guide pipe 72 is embedded inside the card slot 232, making the liquid guide pipe 72 and the card slot 232 form a whole. During the charging process, a large amount of heat will be generated due to the resistance of the card slot 232 itself, and the coolant inside the liquid guide pipe 72 can absorb the heat of the card slot 232, thus playing a role in cooling. When the charging wire 23 is pulled out, the liquid guide pipe 72 on the outer surface of the central shaft 71 will be synchronously pulled out, reducing the mass and total weight of the liquid guide pipe 72 wound around the outer surface of the central shaft 71. At this time, under the elastic force of the connecting spring 75, the connecting seat 73 moves upward in the vertical 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 a traction rope, the traction rope at the bottom of the connecting block 163 is in a slack state 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, driving the second rotating shaft 172 and the pointer 173 to rotate. The direction indicated by the pointer 173 is used to prompt the remaining length of the charging wire 23 wound around the outer surface of the first rotating shaft 21. When the direction indicated by the pointer 173 has an error, by manually turning the handle 133, since the gear column 131 meshes with the toothed plate 77, the relative distance between the entire stroke adjustment device 7 and the ground is adjusted, thereby changing the traction force of the liquid guide pipe 72, achieving the effect of adjusting the direction indicated by the pointer 173 while the charging wire 23 and the liquid guide pipe 72 remain stationary.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
