Description

A charging pile with cable winding function Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a charging pile with a cable winding function. Background Technology

[0002] The application of new energy vehicles is beneficial for alleviating energy and environmental pressures, promoting the optimization of the automotive industry structure, and upgrading consumption. Therefore, in recent years, there has been a strong push to build charging infrastructure to solve the charging problem for electric vehicles.

[0003] The applicant has discovered at least the following technical problems in the prior art: charging piles all come with charging cables of a certain length, but the charging cables of existing charging piles are placed rather haphazardly. When using them, the charging cables need to be organized, and after use, the cables need to be manually retracted or coiled up, which is time-consuming, inconvenient, and can easily damage the lines.

[0004] Summary of the Invention

[0005] The purpose of this invention is to provide a charging pile with a cable reel function, thereby solving the technical problems of existing charging piles where the charging cables are placed haphazardly, requiring arrangement during use and manual winding or coiling after use, which is time-consuming and inconvenient. The various technical effects of the preferred solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A charging pile with a cable winding function includes a main body shell, a cable winding unit, a pull-out limiting unit, a retraction auxiliary unit, a power supply unit, and a charging cable. The cable winding unit is rotatably connected to the main body shell. The pull-out limiting unit and the retraction auxiliary unit are respectively connected to the main body shell and the cable winding unit. The charging cable is wound on the cable winding unit, and one end of the charging cable is connected to the cable winding unit and electrically connected to the power supply unit. After the charging cable is pulled out to the required length, the pull-out limiting unit can restrict the movement of the charging cable. When the pull-out limiting unit releases the limiting position, the retraction auxiliary unit can drive the cable winding unit to rotate in the opposite direction to retract the charging cable.

[0008] Preferably, the winding unit includes a rotating shaft and a winding reel. The two ends of the rotating shaft are rotatably connected to the outer casing of the main body through a bearing structure. The winding reel is connected to the outside of the rotating shaft, and one end of the charging cable is connected to the winding reel.

[0009] Preferably, the pull-out limiting unit includes a ratchet and a pawl, the ratchet is connected to the rotating shaft and the two can rotate synchronously, the pawl is connected to the outer shell of the main body, and the ratchet and the pawl can engage or disengage.

[0010] Preferably, the recycling auxiliary unit includes a coil spring, which is connected to both the main body housing and the winding reel.

[0011] Preferably, the power supply unit includes a charging system circuit board, a collector ring, and a power input line. The collector ring includes a conductive ring and a brush that are electrically connected. The charging system circuit board and the conductive ring are both connected to the winding unit and can move synchronously with the winding unit. The brush is connected inside the housing of the main body. The charging system circuit board is electrically connected to the charging cable. The conductive ring is electrically connected to the charging system circuit board. One end of the power input line passes through the housing of the main body and is electrically connected to the brush.

[0012] Preferably, it also includes a charging display panel, which is connected to the housing and communicates with the charging system circuit board.

[0013] Preferably, it also includes rollers, two of which are connected to the outer casing of the main body, and the two rollers are located at the inlet and outlet of the charging cable and are symmetrically located on both sides of the charging cable.

[0014] Preferably, it also includes a stop ball, which is disposed on the charging line and close to the end connected to the charging gun.

[0015] Preferably, it also includes end caps, two of which are connected to the main body housing, one of which covers the outside of the pull-out limiting unit, and the other of which covers the outside of the power input line near the end of the main body housing.

[0016] Preferably, the current collector ring is offset from the recovery auxiliary unit.

[0017] The beneficial effects of this invention are: when not in use, most of the charging cable is coiled on the winding unit, and the outer casing can store it, making the charging cable neatly arranged and more tidy, while also providing protection.

[0018] When the charging station needs to be used, the user can pull out the charging cable forcefully, gradually pulling the charging cable out from inside the main body shell. When the charging cable is pulled out to the required length, the pull-out limit unit can restrict the movement of the winding unit, making it stop rotating and remain stationary, thereby restricting the movement of the charging cable. During this process, the retraction auxiliary unit stores energy, waiting to start working when the charging station is finished being used.

[0019] When the charging station is no longer in use, the limiting unit needs to be pulled out to release the limit. At this time, the winding unit can rotate, and the retraction auxiliary unit is released, which can drive the winding unit to rotate in the opposite direction. During the reverse rotation, the winding unit can retract the charging cable, so that the charging cable is re-stored in the main body shell and arranged in an orderly manner.

[0020] During the above operation, the charging cable can always maintain current conduction with the power supply unit, and the rotation design of the winding unit will not cause any obstruction to the circuit setup.

[0021] With the assistance of the pull-out limit unit and the retraction auxiliary unit, the cable winding unit and the charging cable can achieve free pull-out and quick retraction of the charging cable, effectively saving time and manpower, making operation convenient, and also protecting the charging cable from damage.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Referring to Figures 1 to 3, this embodiment provides a charging pile with a cable winding function, including a main body shell 1, a cable winding unit 2, a pull-out limiting unit 3, a retraction auxiliary unit 4, a power supply unit 5, and a charging cable 6;

[0031] The main structure of the winding unit 2 is located inside the outer shell 1. The winding unit 2 can be rotatably connected to the outer shell 1, so that the main structure of the winding unit 2 can rotate relative to the outer shell 1.

[0032] The pull-out limiting unit 3 is connected to the main body shell 1 and the winding unit 2 respectively;

[0033] The recycling auxiliary unit 4 is connected to the main body shell 1 and the winding unit 2 respectively;

[0034] The charging cable 6 is coiled on the winding unit 2. One end of the charging cable 6 is connected to the winding unit 2 and electrically connected to the power supply unit 5. The other end of the charging cable 6 passes through the outer shell 1 and is connected to the charging gun.

[0035] When not in use, most of the charging cables 6 are coiled on the winding unit 2, and the outer shell 1 can store them, making the charging cables 6 neatly arranged and more tidy, while also providing protection.

[0036] When the charging station needs to be used, the user can pull out the charging cable 6 and gradually pull it out from the inside of the main body shell 1. When the charging cable 6 is pulled out to the required length, the pull-out limiting unit 3 can restrict the movement of the winding unit 2, so that it stops rotating and remains stationary, thereby restricting the movement of the charging cable 6. During this process, the recovery auxiliary unit 4 stores energy and waits for the charging station to finish its use before starting to work.

[0037] When the charging station is no longer in use, the limiting unit 3 needs to be pulled out to release the limit. At this time, the winding unit 2 can rotate, and the retraction auxiliary unit 4 is released, which can drive the winding unit 2 to rotate in the opposite direction. During the reverse rotation, the winding unit 2 can retract the charging cable 6, so that the charging cable 6 can be stored again by the outer shell 1 of the main body and arranged in an orderly manner.

[0038] During the above operation, the charging cable 6 can always maintain current conduction with the power supply unit 5, and the rotation design of the winding unit 2 will not cause any obstruction to the circuit setup.

[0039] With the assistance of the pull-out limiting unit 3 and the retraction auxiliary unit 4, the winding unit 2 and the charging cable 6 can achieve free pulling out and quick retraction of the charging cable 6, effectively saving time and manpower, and making operation convenient. It can also protect the charging cable 6 and prevent damage.

[0040] As an optional implementation, the winding unit 2 includes a rotating shaft 21 and a winding reel 22. The two ends of the rotating shaft 21 are rotatably connected to the main body housing 1 through a bearing structure. The winding reel 22 is connected to the outside of the rotating shaft 21 and can rotate synchronously with the rotating shaft 21. One end of the charging cable 6 is connected to the winding reel 22. When the charging cable 6 is pulled out, it can drive the winding reel 22 and the rotating shaft 21 to rotate relative to the main body housing 1.

[0041] As an optional implementation, the pull-out limiting unit 3 includes a ratchet 31 and a pawl 32. The ratchet 31 is connected to the rotating shaft 21 and the two can rotate synchronously. The pawl 32 is connected to the main body housing 1. The ratchet 31 and the pawl 32 cooperate with each other to achieve engagement or disengagement between them.

[0042] When the charging station needs to be used, the user can pull out the charging cable 6 by force and gradually pull the charging cable 6 out from the inside of the main body shell 1. When the charging cable 6 is pulled out to the required length, the ratchet 31 and the pawl 32 engage, so that the reel 22 and the rotating shaft 21 cannot rotate and remain stationary, thereby restricting the movement of the charging cable 6.

[0043] When the charging station is no longer in use, the limit of the pull-out limit unit 3 needs to be released, that is, the engagement between the ratchet 31 and the pawl needs to be released so that the two are separated. You can choose to pull the charging cable 6 forward a short distance so that the teeth on the ratchet 31 and the pawl 32 are misaligned and no longer engaged. After releasing the charging cable 6, the charging cable 6 can be retracted under the drive of the retraction auxiliary unit 4. During the retraction process of the charging cable 6, the ratchet 31 and the pawl 32 will not engage, ensuring that the charging cable 6 can be returned to the coil on the reel 22 as a whole.

[0044] As an optional implementation, the recycling auxiliary unit 4 includes a coil spring, which is connected to the main body housing 1 and the winding reel 22 respectively. The coil spring can generate coil force under the action of external force. During the process of pulling out the charging cable 6, the coil spring can store force. When the charging cable 6 is no longer in use and needs to be retracted, after the connection between the ratchet 31 and the pawl 32 is released, the coil spring can return to its original state. During this process, it can drive the winding reel 22 and the rotating shaft 21 to rotate in the opposite direction relative to the main body housing 1, thereby retracting the charging cable 6 and making the charging cable 6 rewind onto the winding reel 22.

[0045] As an optional implementation, the power supply unit 5 includes a charging system circuit board 51, a collector ring 52, and a power input line 53;

[0046] The charging system circuit board 51 is connected to the winding unit 2 and can move synchronously with the winding unit 2. The charging system circuit board 51 is electrically connected to the charging cable 6.

[0047] The collector ring 52 includes a conductive ring and a brush that are electrically connected. The conductive ring is connected to the winding unit 2 and can move synchronously with the winding unit 2. The conductive ring is electrically connected to the charging system circuit board 51. The brush is connected inside the main body housing 1. One end of the power input line 53 passes through the main body housing 1 and is electrically connected to the brush.

[0048] The power input line 53, brush, conductive ring, charging system circuit board 51 and charging cable 6 sequentially conduct current. By setting the collector ring 52, the conductive ring can rotate synchronously with the winding unit 2, while the brush remains stationary. The rotating conductive ring can always maintain current conduction with the brush, and the current is stably transmitted under the premise that the charging system circuit board 51 and the conductive ring rotate relative to each other.

[0049] By adopting the slip ring 52, the slip ring 52 can carry a larger current, thereby effectively ensuring stable output under high current conditions. Furthermore, the use of the slip ring 52 makes the overall structure simpler, effectively simplifying the structural design, protecting the wires, and having a lower failure rate, effectively extending the service life of charging piles with cable winding function.

[0050] As an optional implementation, a charging display board 7 is also included. The charging display board 7 is connected to the housing 1 and is communicatively connected to the charging system circuit board 51. The charging display board 7 can display the charging status in real time, making it convenient for users to observe the charging status intuitively. Here, the charging display board 7 and the charging system circuit board 51 preferably transmit signals wirelessly to reduce the setting of wires and facilitate the overall structural design.

[0051] As an optional implementation, it also includes rollers 8. Two rollers 8 are connected to the outer shell 1 of the main body. The two rollers 8 are located at the inlet and outlet of the charging cable 6 and are symmetrically located on both sides of the charging cable 6. The two rollers 8 can guide the movement of the charging cable 6 at the inlet and outlet, and can also assist the movement of the charging cable 6 to make its movement smoother.

[0052] As an optional implementation, a stop ball 9 is also included. The stop ball 9 is disposed on the charging cable 6 and close to the end connected to the charging gun. The size of the stop ball 9 is larger than the size of the inlet and outlet opening on the main body shell 1 for the charging cable 6 to enter and exit. The stop ball 9 can limit the end of the charging cable 6 connected to the charging gun to prevent it from being completely retracted into the main body shell 1.

[0053] As an optional implementation, it also includes end caps 10, with two end caps 10 connected to the main body housing 1;

[0054] One of the end caps 10 is installed on the outside of the pull-out limiting unit 3, and the end cap 10 can protect the ratchet 31 and pawl 32 located on the outside of the main body housing 1.

[0055] Another end cap 10 is installed on the outside of the power input line 53 near the outer casing 1, and the end cap 10 can protect the power input line 53.

[0056] As an optional implementation, the collector ring 52 and the recycling auxiliary unit 4 are staggered. This arrangement can optimize the spatial design of the structure and reduce the structural size.

[0057] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
