As shown in fig. 1, an embodiment of the present utility model provides a charging pile, which includes a power supply device 10, a charging wire 20 and a wire collecting device 30, wherein one end of the charging wire 20 is connected with the power supply device 10, and the other end of the charging wire 20 is connected with a charging plug 40; the wire collecting device 30 comprises a wire winder 31 and a connecting wire 32, one end of the connecting wire 32 is connected with the wire winder 31, and the other end of the connecting wire 32 is connected with one end of the charging wire 20 close to the charging plug 40; wherein the connection wire 32 can be extended or retracted with respect to the reel 31, and the charging wire 20 can be elongated by an external force and contracted after the external force is removed.

In the present embodiment, the reel 31 is a mechanical device for winding a wire or coil, and typically incorporates a coil spring or spiral spring capable of automatically controlling the winding process of the wire. The connection line 32 can be drawn out by external tension, and after the external force is removed, the connection line 32 is partially retracted and wound inside the reel 31 by the coil spring or the vortex spring.

Based on the above technical solution, before charging the electric bicycle with the charging post, a part of the connecting wire 32 is wound inside the reel 31, and the other end pulls the charging wire 20 near one end of the charging plug 40, so that the charging plug 40 and the charging wire 20 are in a hanging state. During charging, the charging plug 40 is taken down from the charging pile, the charging plug 40 is inserted into the charging socket of the electric bicycle, the charging wire 20 is lengthened along with the movement of the charging plug 40 under the action of external force, the connecting wire 32 is also lengthened along with the movement of the charging plug 40, and meanwhile, the charging plug 40 bears the tensile force of the connecting wire 32. After the charging is finished, the charging plug 40 is pulled out and directly released, the connecting wire 32 is retracted and wound into the reel 31 under the driving of the reel 31, and the charging wire 20 and the charging plug 40 are simultaneously pulled to be retracted together, so that the charging plug 40 and the charging wire 20 are restored to a hanging state. According to the charging pile provided by the embodiment of the invention, the charging plug 40 does not need to be manually replaced after charging, the charging plug 40 can also recover the charging pile to the initial position, and the charging wire 20 can recover to a hanging state after external force disappears by shrinkage, so that the charging wire 20 is prevented from being randomly placed or discarded to cause damage to the charging wire 20 and the charging plug 40.

Illustratively, the charging plug 40 is pulled from the first position to the second position with the charging plug 40 not being charged, the charging wire 20 is changed from the contracted state to the elongated state, and the connecting wire 32 is also changed from the state of suspending the charging wire 20 to the state of tightening the charging wire 20, thereby forming a pulling force on the charging wire 20 and the charging plug 40. After the charging is completed, the charging plug 40 is pulled out and released, and the charging plug 40 returns to the first position from the second position under the tensile force of the connecting wire 32, thereby returning to the original suspended state.

As one embodiment, the charging wire 20 includes a deformation section 21 and a fixing section 22, one end of the deformation section 21 is connected to the power supply device 10, the other end of the deformation section 21 is connected to one end of the fixing section 22, the other end of the fixing section 22 is connected to the charging plug 40, and the connecting wire 32 is connected to the fixing section 22; the deformed segment 21 can be elongated by an external force and contracted after the external force is removed.

Specifically, as shown in fig. 2, the deformation section 21 is a deformation portion of the charging wire 20, and the fixing section 22 is a holding portion of the charging wire 20. During charging, the fixing section 22 of the charging wire 20 is held by hand to insert the charging plug 40 into the charging socket of the electric bicycle, the deformation section 21 of the charging wire 20 is unfolded and elongated along with the movement of the fixing section 22 under the action of external force, the connecting wire 32 is also stretched along with the movement of the fixing section 22, and at the same time, the fixing section 22 bears the tensile force of the connecting wire 32. After the charging is finished, the charging plug 40 is pulled out and directly released, the connecting wire 32 is retracted and wound into the reel 31 under the driving of the reel 31, and meanwhile, the connecting wire 32 pulls the fixing section 22 to retract together, so that the charging plug 40 and the deformation section 21 are restored to a hanging state.

As an embodiment, as shown in fig. 1 and 2, the deformation section 21 has a coil spring shape.

In this example, the deformation section 21 is designed in particular as a helical spring wire, since the helical spring wire is a flexible and elastic structure, the housing of which is made of plastic or rubber and has a helical shape which makes it possible to spread out and enclose the wire or cable bundle, similar to a spring, so that the deformation section 21 can be elongated by an external force and contracted after the external force has been removed, facilitating the spreading or retraction of the charging wire 20, thus avoiding the charging wire 20 being placed or discarded at will.

As an embodiment, as shown in fig. 2, the fixing section 22 is provided with a binding portion 23, and one end of the connection wire 32 is bound to the binding portion 23 so that the connection wire 32 connects the fixing section 22.

Specifically, since the connection line 32 is connected to the fixed segment 22, the connection line 32 may exert a large tensile force on the connection position of the fixed segment 22 during the stretching or retracting of the connection line 32. If the stress is concentrated for a long time, the cable of the fixing section 22 is damaged and destroyed, so that the inner layer battery core is exposed, and electric shock accidents are easy to occur. Based on this problem, the fixing section 22 is provided with the binding portion 23, and the binding portion 23 is used for fixing the connecting wire 32 and can bear strong stress concentration, and even if the connecting wire 32 is repeatedly stretched, the cable structure of the fixing section 22 is not damaged.

Specifically, in order to avoid stress concentration of the same portion of the fixed segment 22 caused by the connecting wire 32, the binding portion 23 may be moved along the axial direction of the fixed segment 22, thereby adjusting the position of the binding portion 23 on the fixed segment 22. Of course, limiting structures can be arranged at two ends of the fixing section 22 to limit the moving range of the binding portion 23, so as to avoid the unstable connection of the connecting wire 32 caused by the movement of the binding portion 23 to the deformation section 21.

As a preferred embodiment, the fixing section 22 is provided with a plurality of binding portions 23, and the plurality of binding portions 23 are arranged at intervals along the axial direction of the fixing section 22.

Also, in this embodiment, a plurality of binding portions 23 may be disposed on the fixed segment 22, so as to avoid stress concentration on the same portion of the fixed segment 22 caused by the connecting wire 32 by adjusting positions of the binding portions 23 on each binding portion 23 of the fixed segment 22.

As an embodiment, as shown in fig. 1 and 2, the deformation section 21 is integrally formed with the fixing section 22.

In this embodiment, the deformation section 21 and the fixing section 22 are integrally formed, and are all made of insulating material to wrap the battery core, and the insulating material provides electrical insulation and mechanical protection for the battery core, so as to ensure that the current can be safe and reliable when the battery core is transmitted, and prevent the electric wire from being damaged or current leakage.

As an embodiment, as shown in fig. 1, 2 and 4, the charging pile further includes a fixing bracket 50, and the fixing bracket 50 is used for installing the power supply device 10 and the wire winding device 30.

Specifically, the power supply device 10 and the wire takeup device 30 are mounted on the same fixing bracket 50 such that the power supply device 10, the wire takeup device 30, and the fixing bracket 50 together constitute the charging module 60. In practice, the charging module 60 generally meets the charging requirements of electric vehicles of different scales and types according to its power and performance. Specifically, the electric bicycle charging system is provided with a plurality of charging modules 60, the charging modules 60 are detachable so as to be convenient to install quickly and install flexibly, and charging specifications among the plurality of charging modules 60 can be different so as to meet the charging requirements of electric bicycles of different types, thereby expanding the application range of the charging pile.

As an embodiment, as shown in fig. 2 and 3, the fixing bracket 50 is provided with a first guide hole 51, and the charging wire 20 is connected to the power supply device 10 through the first guide hole 51.

Specifically, the first guide hole 51 is used to adjust the wire outlet position of the charging wire 20. During charging, the charging wire 20 is pulled outward through the first guide hole 51; after the charging is completed, the charging plug 40 is released, and the charging wire 20 is regulated by the first guide hole 51, so that the charging wire returns to the initial state.

As an embodiment, as shown in fig. 3, the fixing bracket 50 is provided with a second guide hole 52, and the connection wire 32 is connected to the reel 31 through the second guide hole 52.

Specifically, the second guide hole 52 is used to adjust the wire outlet position of the connection wire 32.

They are typically single phase ac charging piles.

(2) Commercial charging pile: commercial charging piles are suitable for commercial places such as shopping centers, hotels, restaurants, parking lots and the like. They typically have higher power and can charge the electric vehicle faster to meet the needs of more customers. Commercial charging piles are typically three-phase ac charging piles that can provide charging for multiple vehicles.

(3) And (3) a quick charging station: the quick charge station is used for long distance trips or situations where quick charge is required. They typically provide very high power, capable of charging the battery of an electric vehicle in a relatively short time. These charging posts typically employ a dc charging technique, allowing the electric vehicle to charge at a faster rate.

(4) Super charging station: super charging stations are typically part of a charging network, located on highways, and are designed specifically for long travel of electric vehicles. They typically have extremely high power and can charge electric vehicles in an extremely short period of time.

In summary, the choice of charging stake depends on the type of electric vehicle, the charging requirement and the usage scenario, and different types of charging stake provide flexible charging solutions for electric vehicles of different scales and types to meet the requirements of different users.
