Description

Technical Field

[0001] The present invention relates to the field of new energy charging piles, and more specifically, to a new energy intelligent two-way charging pile. Background Art

[0002] A new energy charging pile, also known as an electric vehicle charging pile or an electric vehicle charging station, is a facility that provides electrical energy for electric vehicles. It is mainly used to charge the batteries of electric vehicles so that they can continue to drive.

[0003] At present, in order to display the charging amount and facilitate the prompt of charging billing, the existing new energy charging piles are equipped with display screens. One end of the charging pile is connected to the ground charging port for power supply to the charging pile itself. The charging pile itself also comes with a charging head for charging new energy vehicles. When actually using the new energy intelligent two-way charging pile to charge a new energy vehicle, it is necessary to unplug the charging head fixed on the charging pile and insert it into the charging port of the electric vehicle for charging. During this process, the line connecting the charging pile and the charging head is always dragged on the ground. After long-term use, it will be worn. In order to ensure the wear resistance of the line, the entire line casing is thick and thick. When pedestrians pass by, the line dragged on the ground will not attract the attention of passers-by, and there may be a situation where passers-by are tripped by the line. Moreover, the line dragged on the ground will rub against the ground every time it is used and will be repeatedly stepped on, which will also cause wear to the line epidermis. And if there is rain on the ground and it sticks to the line epidermis, and the wire is in long-term contact with rainwater, it will accelerate the corrosion and aging of the cable, shorten its service life, and there are safety hazards.

Detailed Description of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 9 Figures 1 to 9 , a new energy intelligent bidirectional charging pile, including a base 1, with universal wheels provided at the bottom of the base 1. A charging pile main body 2 is fixedly installed on the base 1. A display main body 3 is fixedly provided on the charging pile main body 2. A battery pack 4 is fixedly provided inside the charging pile main body 2. Both the upper and lower ends of the battery pack 4 are electrically connected to a conduction plate 5. The conduction plate 5 is fixedly connected to the charging pile main body 2. A charging plug 7 is provided on the charging pile main body 2. A cable main body 6 is fixedly connected to the charging plug 7. The cable main body 6 electrically connects the conduction plate 5 and the charging plug 7. A rotating groove 8 is provided inside the charging pile main body 2. Limiting rods 9 are fixedly connected to the inner walls on both sides of the rotating groove 8. An outer rotating cylinder 10 is sleeved on the outer surface of the limiting rod 9. A winding cavity 11 is provided inside the outer rotating cylinder 10, and the size of the winding cavity 11 is larger than that of the limiting rod 9. A winding spring 12 is provided in the winding cavity 11. One end of the winding spring 12 is fixedly connected to the outer surface of the limiting rod 9, and the other end of the winding spring 12 is fixedly connected to the inner wall of the winding cavity 11. A spiral groove 13 is provided on the outer rotating cylinder 10. The cable main body 6 is wound around the outer rotating cylinder 10 through the spiral groove 13.

[0033] The cable main body 6 is rotatably connected to the conduction plate 5. The outer end of the cable main body 6 penetrates through the charging pile main body 2, an inner rotating cylinder 14, and a sponge 15 and is fixedly connected to the charging plug 7.

[0034] When using the charging pile main body 2 to charge a new energy vehicle, first unplug the charging plug 7 from the charging pile main body 2, and pull the charging plug 7 to move it to the new energy vehicle for charging. When pulling out the charging plug 7, the cable main body 6 pulled outwards will pass through the spiral groove 13 on the rotating cylinder, causing the outer rotating cylinder 10 to rotate clockwise as shown in Figure 3 so as to achieve the effect of pulling out the cable main body 6 from the charging pile main body 2. After the outer rotating cylinder 10 makes a clockwise rotation, since the limiting rod 9 is fixed in the rotating groove 8, the winding spring 12 is in a contracted state. At this time, under the action of the winding spring 12, the entire cable main body 6 is in a straightened state. Furthermore, the cable main body 6 inserted externally at the new energy vehicle will be straightened and suspended in the air, which is more convenient to be noticed by pedestrians, reducing the situation of tripping pedestrians. It can also reduce the situation where the cable main body 6 hangs on the ground, is repeatedly stepped on, and rubs against the ground repeatedly, avoiding the cable main body 6 being corroded due to the outer skin sticking to rainwater or corrosive liquid when hanging on the ground, improving the service life of the cable main body 6;

[0035] It should be particularly noted here that the universal wheels on the base 1 are for facilitating the movement during the installation of the charging pile main body 2. And only by electrically connecting the cable main body 6 to the conduction plate 5 below the battery pack 4 and electrically connecting to the power supply on the ground can the effect of supplying power to the inside of the charging pile main body 2 be achieved.

[0036] As shown inFigures 6 to 8 As shown, an inner rotating cylinder 14 is rotatably arranged on the charging pile main body 2. A sponge 15 is fixedly connected to the outer end of the inner rotating cylinder 14, and the sponge 15 is annular.

[0037] When the charging plug 7 completes charging of a new energy vehicle and is placed back on the charging pile main body 2, under the action of the contracting spiral spring 12, the entire outer rotating cylinder 10 will rotate counterclockwise. Through the spiral groove 13, the cable main body 6 outside the charging pile main body 2 is wound on the outer rotating cylinder 10. During this process, the entire cable main body 6 is in a straight state and does not contact the ground. When it rains, the rain sticking to the cable main body 6, which is always in contact with the sponge 15, the rain on its surface will be absorbed by the sponge 15 during the process of the cable main body 6 being wound into the charging pile, thus achieving the effect of wiping off the moisture on the surface of the sponge 15, reducing the corrosion of the cable main body 6 by rain on the cable main body 6 skin for a long time, and further improving the service life of the cable main body 6;

[0038] Since the cable main body 6 is rotatably connected to the conduction plate 5, when the cable main body 6 is pulled out from the inside of the charging pile main body 2, the outer rotating cylinder 10 will rotate clockwise. At the same time, the outer rotating cylinder 10 will move to the right in the rotating groove 8 relative to the limiting rod 9. At this time, the connection between the cable main body 6 and the conduction plate 5 will rotate to adapt to this change.

[0039] As Figure 2 、 Figure 3 and Figure 7 shown, a gear 17 is rotatably sleeved on the outer surface of the limiting rod 9. A circle of grooves is opened on the outer surface of one end of the limiting rod 9. The limiting rod 9 limits the gear 17 through the grooves. The inner wall of the rotating groove 8 is rotatably connected to a first sprocket 18. One end of the inner rotating cylinder 14 close to the charging pile main body 2 extends into the charging pile main body 2, and a second sprocket 19 is fixedly sleeved on the outer surface of the end of the inner rotating cylinder 14 extending into the charging pile main body 2. A chain 21 is sleeved on the outer surface of the first sprocket 18. The first sprocket 18 and the second sprocket 19 are driven by the chain 21. Tooth rings 20 are equidistantly arranged on the circumference of the surface of the first sprocket 18 close to the gear 17. The tooth rings 20 are meshed with the gear 17. A plurality of telescopic rods 32 are fixedly connected to the surface of the gear 17 close to the outer rotating cylinder 10. The gear 17 and the outer rotating cylinder 10 are fixedly connected through the plurality of telescopic rods 32.

[0040] When pulling out the cable body 6 and during the process of the cable body 6 being retracted into the charging pile body 2 under the action of the spiral spring 12, since the outer rotating cylinder 10 will rotate relative to the limiting rod 9 in the rotating groove 8, it will drive the gear 17 to rotate through the telescopic rod 32, and then drive the second sprocket 19 to rotate through the toothed ring 20, the first sprocket 18 and the chain 21. The inner rotating cylinder 14 is driven to rotate by the second sprocket 19, and then the sponge 15 rotates. The sponge 15 will shake off the water adsorbed in the sponge 15. It is possible to rotate the sponge 15 twice during each charging process of the charging pile body 2 to shake off the water adsorbed on the sponge 15, reducing the corrosion of the cable body 6 by the rainwater in the sponge 15. Moreover, the sponge 15 can also be used in the next charging process of the charging pile body 2, further improving the service life of the cable body 6.

[0041] As Figure 2 , Figure 3 and Figure 6 shown, an outer cylinder 16 is fixedly connected to the outer surface of the charging pile body 2. An annular protrusion 27 is fixedly sleeved on the inner wall of the outer cylinder 16. The inner diameter of the annular protrusion 27 is smaller than the inner diameter of the inner rotating cylinder 14. The inside of the outer cylinder 16 is divided into an inner cylinder and a drainage cavity 22 by the annular protrusion 27. The inner rotating cylinder 14 is rotationally and sealingly arranged in the vertical cylinder. An extrusion tube 23 is fixedly sleeved on the outer surface of the sponge 15. The extrusion tube 23 is used to extrude the water adsorbed in the sponge 15. Water outlet holes are formed in the extrusion tube 23.

[0042] The extrusion tube 23 is divided into a front pipe 24 and a rear pipe 25 from the inside to the outside in the drainage cavity 22. A plurality of groups of circular grooves 26 are circumferentially and equidistantly formed in both the front pipe 24 and the rear pipe 25. The sponge 15 is in a compressed state in the extrusion tube 23. The circular grooves 26 in the front pipe 24 and the rear pipe 25 are not in the same plane.

[0043] Since the entire extrusion tube 23 is fixed, the circular grooves 26 on the inner wall of the extrusion tube 23, in cooperation with the inner wall of the extrusion tube 23, will exert an extrusion effect on the sponge 15 during the process of the sponge 15 rotating to shake off water, improving the effect of the sponge 15 rotating to shake off the internal water. Moreover, due to the design of the extrusion tube 23, there is an extrusion effect on the sponge 15, making the sponge 15 contact the surface of the cable body 6 more closely and improving the adsorption effect of the sponge 15 on the rainwater on the surface of the cable body 6;

[0044] Moreover, since the extrusion tube 23 is divided into a front pipe 24 and a rear pipe 25, when the front pipe 24 squeezes the sponge 15, part of the water in the sponge 15 located in the front pipe 24 will enter the position of the sponge 15 in the rear pipe 25 due to the extrusion of the front pipe 24. Since the water in the sponge 15 in the rear pipe 25 increases at this time, the centrifugal force of the water in the sponge 15 will increase, improving the efficiency of the sponge 15 shaking off the internal water;

[0045] It should be specifically noted here that: the magnitude of the centrifugal force is affected by the gravity of the object. According to the centrifugal force formula: F = m·r·ω·ω, where the rotation radius remains unchanged, the rotation angular velocity remains unchanged, and the mass increases, the centrifugal force increases.

[0046] As Figure 2 , Figure 3 and Figure 6 shown, the sponge 15 is located in the drainage cavity 22. A notch is provided at the bottom of the drainage cavity 22, and the direction of the notch is vertically downward.

[0047] Since the entire sponge 15 is within the extrusion tube 23, during the process of the sponge 15 throwing out water, the water will be thrown into the drainage cavity 22. Due to the presence of the inner wall of the drainage cavity 22, the thrown-out water will be blocked by the drainage cavity 22 and flow down along the inner wall of the drainage cavity 22 and be discharged through the notch, which can avoid the situation where rainwater is thrown onto the user during the process of pulling out the cable main body 6 and putting back the charging plug 7.

[0048] As Figure 6 shown, an outer cover plate 28 is rotatably provided at the outer end of the outer cylinder 16. The outer cover plate 28 is fixedly connected to the outer end of the sponge 15. A scraper 29 is fixedly connected to the outer surface of one side of the outer cover plate 28, and the scraper 29 is slidably provided in the drainage cavity 22.

[0049] The top end of the scraper 29 contacts the drainage cavity 22, the inner end of the scraper 29 contacts the outer wall of the extrusion tube 23, and the size of the scraper 29 is the same as the size of the extrusion tube 23.

[0050] When the inner rotating cylinder 14 drives the sponge 15 to rotate, the sponge 15 will drive the scraper 29 to rotate in the drainage cavity 22 through the outer cover plate 28, thereby wiping off the rainwater on the inner wall of the drainage cavity 22 and the outer surface of the extrusion tube 23, enabling the thrown-out water to quickly leave the drainage cavity 22 and reducing the water remaining in the drainage cavity 22 from corroding the cable main body 6.

[0051] As Figure 6 shown, a water blocking cover 30 is fixedly connected to the outer surface of the charging pile main body 2, and the water blocking cover 30 is spherical. A water blocking cavity 31 is provided inside the water blocking cover 30, and the water blocking cavity 31 is spherical. An opening is provided below the water blocking cover 30, and the opening is used for drainage. The outer cylinder 16 is provided in the water blocking cavity 31.

[0052] In order to reduce the influence of rainwater flowing down along the outer surface of the charging pile main body 2 to the sponge 15 on the normal function of the sponge 15 on rainy days, the water blocking cover 30 can effectively isolate the sponge 15 from the external rainwater and ensure the use effect of the sponge 15.

[0053] Usage method: When using the charging pile main body 2 to charge a new energy vehicle, first unplug the charging plug 7 from the charging pile main body 2, and pull the charging plug 7 to move it to the new energy vehicle for charging. When pulling out the charging plug 7, the cable main body 6 pulled outwards will pass through the spiral groove 13 on the rotating cylinder, causing the outer rotating cylinder 10 to rotate clockwise as shown in Figure 3 shown in Figure 3 , thereby achieving the effect of pulling out the cable main body 6 from the charging pile main body 2. After the outer rotating cylinder 10 makes a clockwise rotation, since the limiting rod 9 is fixed in the rotating groove 8 and the coil spring 12 is in a contracted state, at this time, under the action of the coil spring 12, the entire cable main body 6 is in a straightened state. Furthermore, the cable main body 6 inserted externally at the new energy vehicle will be straightened and suspended in the air, which is more convenient to be noticed by pedestrians, reducing the situation of tripping pedestrians, and can also reduce the situation where the cable main body 6 droops on the ground, is repeatedly stepped on, and rubs against the ground repeatedly, avoiding the cable main body 6 being corroded due to the outer skin sticking to rainwater or corrosive liquid when hanging on the ground, and improving the service life of the cable main body 6.

[0054] The above is only a preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
