In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0067] In some embodiments, a charging station is provided. The charging station is configured to charge a device to be charged, for example, an electric vehicle. The charging station is portable and can be installed with the vehicle to facilitate charging the electric vehicle at any time, thereby improving charging convenience.

[0068] Figure 1 The figure shows a structural diagram of a charging pile. Figure 2 The figure shows an exploded view of a charging pile. Figure 3 The figure shows a structural diagram of the charging pile after omitting the outer shell 200. Figure 4 Shown is a cross-sectional view of a charging pile.

[0069] The charging station includes a charging gun 600. The charging gun 600 is configured to connect to a charging port of a device to be charged. For example, the charging gun 600 is connected to a charging port of an electric vehicle.

[0070] The charging station includes a power cord 700. The power cord 700 is configured to be connected to a power source. For example, the power cord 700 is connected to the mains.

[0071] The charging pile includes a housing 10 . The housing 10 forms the outer contour of the charging pile. A first accommodating cavity 140 is formed inside the housing 10 .

[0072] The charging station includes a roller 300. The roller 300 is disposed within the first accommodating chamber 140 and is configured to rotate to reel in the charging cable 610 of the charging gun 600. In other words, the roller 300 is disposed within the housing 10 and rotates under the action of an external force. This rotation reels in the charging cable 610, wrapping it around the roller 300. Figure 5 FIG. 1 is a structural diagram of the drum portion 300 .

[0073] The charging station includes an electronic control component 400. The electronic control component 400 is fixedly mounted within the drum portion 300 and is configured to rotate with the drum portion 300. The charging cable 610 is connected to the electronic control component 400. For example, a second accommodating cavity 340 is formed within the drum portion 300, and the electronic control component 400 is fixedly mounted within the second accommodating cavity 340.

[0074] The charging station includes a slip ring 500. The slip ring 500 is fixed to the drum 300 and is configured to rotate with the drum 300. One end of the slip ring 500 is located in the second accommodating cavity 340 of the drum 300 to connect to the electronic control component 400. The other end of the slip ring 500 is located outside the drum 300 and connected to the power cord 700 to ensure continuity of the charging circuit.

[0075] The charging station includes a wiring section 900. This section is fixed to the housing 10 and connects the wiring harness of the slip ring 500 and the power cord 700. The wiring section 900 provides an independent mounting area for the connection between the slip ring 500 and the power cord 700, helping to improve the reliability of the electrical connection between them and, in turn, the reliability of charging.

[0076] The connection portion 900 is offset from the axis of the slip ring 500. In other words, after the wire harness of the slip ring 500 is led out from the main body of the slip ring 500, it is bent at a certain angle and extended a certain distance. The connection position between the wire harness of the slip ring 500 and the power line 700 is away from the main body of the slip ring 500, which facilitates wiring operations and line maintenance.

[0077] When the charging pile is in use, the charging gun 600 is pulled, the drum part 300 rotates in a first direction (for example, counterclockwise), the charging cable 610 is led out from the drum part 300, the charging gun 600 is connected to the charging port of the electric vehicle, and the power cord 700 is connected to the power supply. Under the action of the slip ring 500, the charging circuit is connected to charge the electric vehicle.

[0078] After charging is completed, the charging gun 600 and the power cord 700 are pulled out, and the drum part 300 rotates in the second direction (for example, clockwise) under the action of an external force. When the drum part 300 rotates, the charging cable 610 is reeled in, and the charging cable 610 is wound around the drum part 300, thereby achieving storage of the charging cable 610.

[0079] In some embodiments, reference Figure 3 The wiring section 900 includes multiple wiring cavities 910 arranged sequentially. The multiple wiring cavities 910 serve as branching points for multiple wiring harnesses. The multiple wiring harnesses of the power cable 700 (denoted as the first wiring harness 710 ) and the multiple wiring harnesses of the slip ring 500 (denoted as the second wiring harness 510 ) are connected within the multiple wiring cavities 910 .

[0080] This arrangement helps improve the reliability and stability of the wiring harness connection, facilitating subsequent maintenance and upgrades. In addition, the multiple wiring cavities 910 separate the multiple wiring harnesses, which is beneficial for heat dissipation at the wiring location.

[0081] In some embodiments, after the second wire harness 510 of the slip ring 500 and the first wire harness 710 of the power cord 700 are connected in the wiring cavity 910 , the wiring cavity 910 is waterproofed and glued to further improve wiring reliability.

[0082] In some embodiments, reference Figure 3 and Figure 6 The wiring portion 900 includes a circumferential sidewall 920. A plurality of spaced-apart partitions 930 are provided within the space enclosed by the circumferential sidewall 920. The partitions 930 are partition structures that divide the space enclosed by the circumferential sidewall 920 into a plurality of sequentially arranged wiring cavities 910. A plurality of wire passage openings 921 are provided on two opposing walls of the circumferential sidewall 920. One side of the wire passage openings 921 is open to facilitate the passage of the wiring harness.

[0083] Multiple wire openings 921 are provided corresponding to the multiple wiring cavities 910. The multiple first wires 710 of the power cable 700 extend into the wiring cavity 910 through the multiple wire openings 921 on one side, and the multiple second wires 510 of the slip ring 500 extend into the wiring cavity 910 through the multiple wire openings 921 on the opposite side. The wire openings 921 separate and limit the wires, allowing the multiple wires to extend smoothly into the wiring cavity 910.

[0084] A terminal 940 is provided in the wiring cavity 910 , and the second wire harness 510 of the slip ring 500 and the first wire harness 710 of the power line 700 are connected at the terminal 940 , which facilitates wiring.

[0085] In some embodiments, reference Figure 3 and Figure 4 , the wiring cavity 910 extends along the height direction of the charging pile, and the slip ring 500 is arranged along the axial direction of the charging pile. For example, the slip ring 500 is arranged along the central axis direction of the charging pile, and the wiring cavity 910 is arranged above the slip ring 500. After the second wiring harness 510 of the slip ring 500 is led out from the main body of the slip ring 500, it is bent upward for a certain distance and extends into the wiring cavity 910. The first wiring harness 710 of the power cord 700 extends downward into the wiring cavity 910. The wiring harnesses in the wiring cavity 910 all extend along the height direction of the charging pile, which is convenient for connection in the wiring cavity 910.

[0086] In some embodiments, reference Figure 4The first outer shell 210 is provided with a mating portion 211, which is snap-fitted with the wiring portion 900 of the first inner shell 120, further isolating the multiple wiring cavities 910 from each other, making the wiring harness connection more stable and reliable.

[0087] In some embodiments, reference Figure 5 The drum unit 300 includes a drum body 310. Baffles, designated as a first baffle 320 and a second baffle 330, are disposed on opposite sides of the drum body 310. The outer diameters of the first and second baffles 320 and 330 are larger than those of the drum body 310. The charging cable 610 is wrapped around the outer circumference of the drum body 310, with the first and second baffles 320 and 330 acting as position limiters.

[0088] The drum body 310 is provided with a fourth wire threading port 311 , through which the charging cable 610 extends into the second accommodating cavity 340 to be connected to the electronic control component 400 .

[0089] In some embodiments, the first baffle 320 is rotatably connected to the inner wall of the housing 10 , and the second baffle 330 is rotatably connected to the inner wall of the housing 10 , so that the drum portion 300 can be rotatably arranged in the housing 10 .

[0090] In some embodiments, reference Figure 4 The housing 10 includes an outer housing 200 and an inner housing 100. The outer housing 200 is disposed outside the inner housing 100. A mounting cavity is formed between the outer housing 200 and the inner housing 100, and the wiring portion 900 is disposed within the mounting cavity. The inner housing 100 forms a first accommodating cavity 140. The inner housing 100 is provided with a threading port for the wiring harness to pass through, and the threading port is connected to the mounting cavity.

[0091] In other words, the roller portion 300 is positioned within the inner cavity of the inner housing 100, while the wiring section 900 is positioned within the mounting cavity between the inner and outer housings 100 and 200. The second wiring harness 510 of the slip ring 500 extends through a threading port into the mounting cavity, while the external power cable 700 extends inward through the threading port into the mounting cavity. The wiring section 900 is positioned between the outer and inner housings 200 and 100, fully utilizing the space between them and resulting in a compact structure.

[0092] In some embodiments, reference Figure 2 and Figure 4The inner housing 100 includes a circumferential housing 110, which has a circumferential frame structure. A first inner housing 120 is disposed on one side of the circumferential housing 110, and a second inner housing 130 is disposed on the opposite side. For example, the first inner housing 120 is disposed on the right side of the circumferential housing 110, and the second inner housing 130 is disposed on the left side. The circumferential housing 110 is fixedly connected to the first inner housing 120 and the second inner housing 130 using snaps, screws, or other means. The circumferential housing 110, the first inner housing 120, and the second inner housing 130 enclose a first accommodating chamber 140.

[0093] The outer shell 200 includes a first outer shell 210 and a second outer shell 220. The first outer shell 210 is disposed outside the first inner shell 120, with a mounting cavity formed between the first inner shell 120 and the first outer shell 210. The second outer shell 220 is disposed outside the second inner shell 130.

[0094] The wiring section 900 is mounted on the first inner housing 120. The first outer housing 210 is removably mounted on the outside of the first inner housing 120 using clips, screws, or other means. When the first outer housing 210 is removed, the wiring section 900 is exposed and located in an open area, facilitating wiring operations and line maintenance.

[0095] In some embodiments, reference Figure 6 The connection portion 900 and the first inner shell 120 are an integrally formed structure, which is easy to process and manufacture.

[0096] In some embodiments, reference Figure 4 The first inner housing 120 includes a main body and a restraining portion 127 disposed opposite the second wiring harness 510 of the slip ring 500. The slip ring, the second wiring harness 510, and the restraining portion 127 are arranged in sequence along the axial direction of the drum portion 300. The main body and the restraining portion 127 are integrally formed. The restraining portion 127 is configured to limit the position of the second wiring harness 510.

[0097] In some embodiments, reference Figure 4 A first mounting cavity 11 is formed between the first inner housing 120 and a side portion of the drum portion 300. For example, the first mounting cavity 11 is formed between the first inner housing 120 and the first baffle 320 of the drum portion 300. A second mounting cavity 12 is formed between the first inner housing 120 and the first outer housing 210. The wiring portion 900 is disposed within the second mounting cavity 12.

[0098] The slip ring 500 is fixedly connected to the first baffle 320. One end of the slip ring 500 is located in the second accommodating cavity 340 of the drum portion 300 to connect to the electronic control component 400. The other end of the slip ring 500 is located outside the drum portion 300, that is, in the first installation cavity 11. The first inner housing 120 is provided with a first threading opening 124, which connects the first installation cavity 11 and the second installation cavity 12. The second wire harness 510 of the slip ring 500 extends from the first installation cavity 11 to the second installation cavity 12 through the first threading opening 124. The second wire harness 510 of the slip ring 500 extends to the wiring portion 900 to connect to the power cord 700.

[0099] The first installation cavity 11 provides an independent spatial area for the extension of the second wiring harness 510 of the slip ring 500. The extension of the second wiring harness 510 of the slip ring 500 is in a different spatial area from the wiring position. The first installation cavity 11 limits the second wiring harness 510 of the slip ring 500, and the first wire threading port 124 also limits the routing of the second wiring harness 510 of the slip ring 500, thereby helping to improve wiring reliability.

[0100] In addition, when the second wire harness 510 of the slip ring 500 is routed in the first installation cavity 11 , the second wire harness 510 of the slip ring 500 has a small fold line radius in the first installation cavity 11 , which helps to improve the compactness of the structure.

[0101] In some embodiments, reference Figure 4 and Figure 6 The first inner housing 120 is provided with a groove portion, denoted as a first groove portion 121, which is recessed in a direction away from the drum portion 300. The first groove portion 121 includes a circumferential wall 122 and a side wall 123. The circumferential wall 122 and the side wall 123 constitute part of the side wall of the first installation cavity 11. The circumferential wall 122 is provided with a first threading port 124.

[0102] When the second wiring harness 510 of the slip ring 500 is routed within the first groove 121, it abuts against the side wall 123 and extends along the side wall 123 toward the first threading opening 124. Because the first outer shell 210 is detachably mounted, the side wall 123 limits the second wiring harness 510 of the slip ring 500, preventing the second wiring harness 510 of the slip ring 500 from directly abutting against the first outer shell 210, thereby improving the installation reliability of the first outer shell 210.

[0103] In some embodiments, reference Figure 4The first baffle 320 is provided with a second groove 321. The second groove 321 is recessed away from the first inner housing 120, that is, recessed toward the inner cavity of the drum unit 300. The second groove 321 directly faces the first groove 121. The first groove 121 and the second groove 321 form the first installation cavity 11. The provision of the second groove 321 further increases the volume of the first installation cavity 11, facilitating the routing of the second wiring harness 510 of the slip ring 500.

[0104] The circumferential outer wall of the first groove portion 121 and the circumferential inner wall of the second groove portion 321 are nested and can rotate relative to each other to achieve a rotational connection between the first baffle 320 and the first inner shell 120 to realize a rotational setting of the drum portion 300.

[0105] In some embodiments, reference Figure 3 、 Figure 4 as well as Figure 6 A second wire threading opening 125 is provided on the first inner shell 120, and a third wire threading opening 111 is provided on the circumferential shell 110. The power cord 700 extends into the first accommodating cavity 140 through the third wire threading opening 111, and then extends into the second installation cavity 12 through the second wire threading opening 125.

[0106] In other words, third threading opening 111 is provided on the circumferential side of housing 10. External power cable 700 extends into housing 10 through third threading opening 111, abuts against first inner housing 120, and then extends into second mounting cavity 12 through second threading opening 125 to connect with second wiring harness 510 of slip ring 500. The routing of power cable 700 fully utilizes the space within housing 10, resulting in a compact structure.

[0107] In some embodiments, reference Figure 7 A wire fixing portion 126 is provided on the inner side of the first inner shell 120. The wire fixing portion 126 is fixed to the inner side of the first inner shell 120 by screws or the like. The wire fixing portion 126 limits the power cord 700 and improves the routing reliability of the power cord 700.

[0108] In some embodiments, ratchet teeth 331 are provided on the roller portion 300, and a pawl 223 is provided on the shell 10. The ratchet teeth 331 cooperate with the pawl 223, and the shell 10 is configured to drive the roller portion 300 to rotate when rotating along a set direction (for example, the second direction described above).

[0109] When the housing 10 is rotated along the first direction described above, the housing 10 rotates idle, which can prevent the cable in the accommodating cavity from becoming loose when the housing 10 is rotated along the first direction.

[0110] In some embodiments, the second outer shell 220 is rotatably connected to the second inner shell 130. For example, referring to Figure 8 The second outer shell 220 is provided with a raised portion 221 extending along the circumference of the second outer shell 220. A hook is provided at the end of the raised portion 221. A corresponding slideway (not shown) is provided on the second inner shell 130. The raised portion 221 is located within the slideway, and the hook engages with the sidewall 123 of the slideway, achieving a rotational connection between the second outer shell 220 and the second inner shell 130.

[0111] Reference Figure 5 The roller portion 300 is provided with ratchet teeth 331, specifically, the second baffle 330 is provided with ratchet teeth 331, and the ratchet teeth 331 extend along the circumference of the second baffle 330. Figure 8 A pawl 223 is provided on the second outer shell 220, and the ratchet teeth 331 cooperate with the pawl 223. The second outer shell 220 is configured to drive the roller part 300 to rotate when it rotates.

[0112] In other words, when the second outer shell 220 rotates under the action of an external force, the second outer shell 220 drives the roller portion 300 to rotate synchronously through the cooperation between the ratchet teeth 331 and the pawl 223 .

[0113] The cooperation between the ratchet teeth 331 and the pawl 223 can avoid the problem of the charging cable 610 being stuck due to the reverse rotation of the drum part 300, thereby reliably achieving one-way winding of the charging cable 610 and avoiding the phenomenon that the user rotates the second outer shell 220 in the reverse direction during the winding process, causing the drum part 300 to be stuck.

[0114] In some embodiments, reference Figure 1 A handle 60 is provided on the second outer shell 220 for the user to manually crank the second outer shell 220, making the storage of the gun line more convenient. In combination with the cooperation between the above-mentioned ratchet teeth 331 and the pawl 223, it can reliably achieve one-way winding, avoiding the phenomenon that the user cranks the handle 60 in the opposite direction, causing the gun line to be scattered and making it impossible to smoothly retract the gun line.

[0115] In some embodiments, reference Figure 1 and Figure 4 The display unit 50 is provided on the side of the drum unit 300. Figure 8 The second outer shell 220 is provided with an opening 222 for exposing the display unit 50. The display unit 50 is configured to display the charging status, etc. The display unit 50 also integrates a button function for adjusting the charging gear.

[0116] In some embodiments, reference Figure 1 A handle 20 is provided on the top of the circumferential shell 110 to facilitate hand-held pickup of the charging pile.

[0117] In some embodiments, a first wire clamp 30 is provided on a side of the circumferential housing 110 for fixing the charging gun 600 .

[0118] In some embodiments, a second wire clamp (not shown) is further provided on the side of the circumferential housing 110 for fixing the power cord 700 .

[0119] In some embodiments, reference Figure 10 The circumferential housing 110 is provided with a wiring opening 112 through which the charging cable 610 passes. A brush 40 is provided at the wiring opening 112. When the charging cable 610 is reeled in, the brush 40 cleans away dust and other foreign matter on the charging cable 610, keeping the charging cable 610 clean.

[0120] In some embodiments, reference Figures 9 to 11 The charging pile also includes a base 800, which is configured to place the main body of the charging pile.

[0121] The base 800 includes a front plate 820, a back plate 830 and a bottom plate 810. The front plate 820 and the back plate 830 extend upward from the bottom plate 810, and a storage space for placing the main body of the charging pile is formed therebetween. The top of the storage space is open.

[0122] The back panel 830 is fixed to a mounting carrier such as a wall by means of screws or the like. When the charging pile is not in use, it is placed on the base 800 to store the charging pile.
