The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0041] Most of the charging piles for new energy vehicles are fixedly installed in the charging parking spaces. However, when the charging parking spaces are occupied, the new energy vehicles that need to be charged cannot be charged, and the average utilization rate of the charging piles is low. In the related prior art, some charging parking spaces also use mobile charging piles, that is, the charging piles can be moved to any parking space and connected to the couplers on the parking space. However, since the charging piles are equipped with cables and charging guns, the charging piles are inconvenient to move.

[0042] In order to solve the above problems, Figures 1 to 7 As shown, the utility model first provides a charging device to facilitate the mobile charging pile.

[0043] like Figure 1 to Figure 2 As shown, specifically, the charging device includes a track assembly 1, a charging pile 2 and at least two charging assemblies 3, wherein: the track assembly 1 includes a first track 11 and at least two second tracks 12, each second track 12 is arranged at intervals along the length direction of the first track 11, and one end of each second track 12 can be connected to the first track 11; the charging pile 2 is arranged on the track assembly 1, and can move along the first track 11 and the second track 12; the charging assembly 3 is arranged one-to-one with the second track 12, and the charging assembly 3 is arranged at one end of the corresponding second track 12 away from the first track 11, and each charging assembly 3 includes a power supply 31 and a charging gun 32, and the power supply 31 and the charging gun 32 can be electrically connected to the charging pile 2 located on the corresponding second track 12. It should be noted that the second track 12 and the charging assembly 3 are arranged one-to-one with the parking space.

[0044] In the charging device provided by the embodiment of the utility model, when the new energy vehicle needs to be charged, the charging pile 2 is controlled to move along the first track 11. When the charging pile 2 moves to the junction of the first track 11 and the second track 12 corresponding to the parking space, the charging pile 2 is controlled to move from the first track 11 to the second track 12, and the charging pile 2 is controlled to move along the second track 12 to the end away from the first track 11 and then stop; the power supply 31 and the charging gun 32 of the corresponding charging component 3 are electrically connected to the charging pile 2, and the charging gun 32 is connected to the charging port of the new energy vehicle to start charging. The power supply 31 can supply power to the charging pile 2, and the charging pile 2 can convert the AC power output by the power supply 31 into AC power or DC power suitable for charging the new energy vehicle, and output the converted AC power or DC power to the new energy vehicle through the charging gun 32; after charging is completed, the charging gun 32 is separated from the charging port of the new energy vehicle, and the power supply 31 and the charging gun 32 are separated from the charging pile 2. In this way, the charging pile 2 can move to any parking space provided with the second track 12 and connect with the corresponding charging component 3 to charge the new energy vehicle in the parking space, thereby preventing the problem that the charging parking space is occupied and the new energy vehicle that needs to be charged cannot be charged, thereby improving the average utilization rate of the charging pile 2; separating the power supply 31 and the charging gun 32 from the charging pile 2 can prevent the connecting cables between the charging pile 2 and the power supply 31 and the charging gun 32 from affecting the normal movement of the charging pile 2, and can also simplify the structure of the charging pile 2 to facilitate the movement of the charging pile 2.

[0045] Furthermore, after charging is completed, the charging pile 2 can slide in the opposite direction along the second track 12 to the first track 11, and then slide in the opposite direction along the first track 11 to the initial position. Alternatively, the charging pile 2 can also stay on the second track 12, and when new energy vehicles in other parking spaces need to be charged, the charging pile 2 can be controlled to slide in the opposite direction along the second track 12 to the first track 11, and then slide along the first track 11 to the second track 12 corresponding to other parking spaces.

[0046] The number of charging piles 2 can be set to one, two or more according to actual needs. When the number of charging piles 2 is more than two, the charging piles 2 in the second track 12 can avoid hindering the movement of other charging piles 2 in the first track 11.

[0047] like Figure 1 As shown, the track assembly 1 can be set on the ground, and the charging pile 2 moves on the ground track without building a steel frame structure or wall, so that the charging device can be used in a variety of environments such as outdoor open-air parking lots and indoor parking lots.

[0048] like Figure 1As shown, in one embodiment, along the length direction of the first track 11, when all parking spaces are divided on one side of the first track 11, each second track 12 can be arranged on the same side of the first track 11. In another embodiment, along the length direction of the first track 11, when some parking spaces are divided on one side of the first track 11 and the rest of the parking spaces are divided on the other side of the first track 11, each second track 12 is arranged on both sides of the first track 11, that is, some second tracks 12 are arranged on one side of the first track 11, and the rest of the second tracks 12 are arranged on the other side of the first track 11. The specific arrangement of the second tracks 12 can be adjusted according to the division method of the parking spaces.

[0049] like Figure 2 and Figure 5 As shown, in one embodiment, the first track 11 includes a first section 111 and a second section 112 arranged in parallel and spaced apart, and each second track 12 includes a third section 121 and a fourth section 122 arranged in parallel and spaced apart; the charging pile 2 includes a main body 24 and a roller 25 rotatably disposed at the bottom of the main body 24, and the number of the rollers 25 is at least two, and some of the rollers 25 move along the first section 111 and the third section 121, and the remaining rollers 25 move along the second section 112 and the fourth section 122. The first section 111 and the second section 112 can limit the rollers 25 to the inside or outside of the first track 11 to ensure the stability of the rollers 25 when moving on the first track 11. Specifically, limiting the roller 25 to the inner side of the first track 11 means limiting the roller 25 moving along the first section 111 to the side of the first section 111 facing the second section 112, and limiting the roller 25 moving along the second section 112 to the side of the second section 112 facing the first section 111; limiting the roller 25 to the outer side of the first track 11 means limiting the roller 25 moving along the first section 111 to the side of the first section 111 away from the second section 112, and limiting the roller 25 moving along the second section 112 to the side of the second section 112 away from the first section 111. Similarly, the third section 121 and the fourth section 122 can also limit the roller 25 to the inner side or the outer side of the second track 12 to ensure the stability of the roller 25 when moving on the second track 12.

[0050] The number of rollers 25 is preferably four as shown in the figure, wherein two rollers 25 move along the first section 111 and the third section 121, and the remaining two rollers 25 move along the second section 112 and the fourth section 122, thereby ensuring the stability of the charging pile 2 and avoiding increasing the complexity of the structure of the charging pile 2. The first section 111, the second section 112, the third section 121 and the fourth section 122 may be an I-shaped track, a trapezoidal track or a rectangular track.

[0051] Of course, in other embodiments, the first track 11 and the second track 12 can also be set as one track, and the outer periphery of the roller 25 is provided with a groove that can cooperate with the track, and the inner walls on both sides of the groove are respectively limited to the two sides of the track to ensure the stability of the roller 25 when moving on the first track 11 and the second track 12.

[0052] like Figure 5 As shown, the charging pile 2 also includes a power assembly (not shown) disposed on the main body 24, and the power assembly is used to drive the charging pile 2 to move along the first track 11 and the second track 12. The power assembly is used to provide power to the charging pile 2, and the charging pile 2 does not need to be connected to an external power source, so as to prevent the connection cable between the charging pile 2 and the external power source from affecting the normal movement of the charging pile 2, so that the charging pile 2 does not need to drag the cable during the movement. Among them, the power assembly can be a motor, and the motor can drive the roller 25 to rotate relative to the main body 24, so that the roller 25 moves along the first track 11 and the second track 12.

[0053] Specifically, the power assembly includes a battery (not shown), which can be electrically connected to the power supply 31. When the battery power is lower than a set value, the battery can be electrically connected to the power supply 31 when the charging pile 2 moves to any second track 12, so that the battery can be charged by the power supply 31 to ensure that the battery has enough power to drive the charging pile 2 to move.

[0054] like Figures 1 to 4 As shown, in one embodiment, the track assembly 1 further includes at least two switches 13, which are arranged one-to-one with the second track 12, and are arranged between the corresponding second track 12 and the first track 11; the switch 13 has a first state and a second state, in which the switch 13 disconnects the corresponding second track 12 from the first track 11, and in the second state, the switch 13 connects the corresponding second track 12 with the first track 11. The switch 13 is used to provide steering capability for the charging pile 2. When all the switches 13 are in the first state, the charging pile 2 always moves along the first track 11 or the second track 12, and cannot move from the first track 11 to the second track 12, or from the second track 12 to the first track 11; when a certain switch 13 is in the second state, the charging pile 2 can move from the first track 11 to the corresponding second track 12, or from the corresponding second track 12 to the first track 11, so that the charging pile 2 can accurately move to the target second track 12, and the structures of the track assembly 1 and the charging pile 2 are relatively simple.

[0055] like Figures 2 to 4As shown, along the length direction of the first track 11, the first track 11 is provided with at least two notches 113, and the notches 113 are arranged one-to-one with the second track 12; the switch 13 is arranged at the corresponding notches 113, and in the first state, the two ends of the switch 13 are respectively connected to the two ends of the corresponding notches 113, and in the second state, the two ends of the switch 13 are respectively connected to the first track 11 and the second track 12. When all the switches 13 are in the first state, each switch 13 connects the two ends of the corresponding gap 113, so that the first track 11 and the switch 13 form a continuous track, and the charging pile 2 can always move along the continuous track or along the second track 12; when a switch 13 is in the second state, the switch 13 connects the first track 11 and the second track 12, so that the charging pile 2 can move from the first track 11 to the corresponding second track 12 through the switch 13, or from the corresponding second track 12 to the first track 11 through the switch 13, and because the two ends of the corresponding gap 113 are disconnected in the second state, the charging pile 2 at the gap 113 cannot continue to move along the first track 11. Thereby, the accuracy of the movement path of the charging pile 2 can be guaranteed.

[0056] like Figure 3 to Figure 4 As shown, in the illustrated embodiment, the turnout 13 includes a fifth section 131 and a sixth section 132. The second track 12 can be arranged on the side of the first section 111 away from the second section 112, or on the side of the second section 112 away from the first section 111. For ease of description, the following takes the case where the second track 12 is arranged on the side of the second section 112 away from the first section 111 as an example, the second section 112 is provided with a notch 113, the third section 121 and the fourth section 122 are respectively connected to both ends of the notch 113, and one end of the fifth section 131 and the sixth section 132 are both connected to the end connected to the notch 113 and the third section 121. In the first state, the other end of the fifth section 131 is disconnected from the first section 111, and the other end of the sixth section 132 is connected to the end connected to the notch 113 and the fourth section 122; in the second state, the other end of the fifth section 131 is connected to the first section 111, and the other end of the sixth section 132 is disconnected from the end connected to the notch 113 and the fourth section 122. Of course, the turnout 13 may also include only one track, and one end of the turnout 13 is connected to the end where the gap 113 and the third section 121 are connected. In the first state, the other end of the turnout 13 is connected to the end where the gap 113 and the fourth section 122 are connected; in the second state, the other end of the turnout 13 is connected to the first section 111.

[0057] Of course, in other embodiments, the track assembly 1 may not be provided with the turnout 13, and a steering structure may be added at the roller 25, so that the steering capability of the charging pile 2 can be achieved through the cooperation of the power assembly, the steering structure and the roller 25.

[0058] like Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment, the power supply 31 includes a first input terminal 311 and a first output terminal 312, the first output terminal 312 is used to be electrically connected to the power grid, and the first input terminal 311 is electrically connected to the corresponding charging gun 32; the charging pile 2 includes a second input terminal 21 and a second output terminal 22, and the second input terminal 21 and the second output terminal 22 can be electrically connected to the first output terminal 312 and the first input terminal 311 respectively. After the charging pile 2 moves to the corresponding second track 12, the first output terminal 312 and the first input terminal 311 of the corresponding power supply 31 are connected to the second input terminal 21 and the second output terminal 22 of the charging pile 2 respectively, and the alternating current of the power grid can be transmitted to the charging pile 2 through the first output terminal 312 and the second input terminal 21, and the charging pile 2 transmits the converted alternating current or direct current to the charging gun 32 through the second output terminal 22 and the first input terminal 311, and the charging gun 32 then outputs to the new energy vehicle. In this way, the charging gun 32 is fixed to the power source 31, which can simplify the structure of the charging component 3, and the charging gun 32 is electrically connected to the charging pile 2 through the power source 31, so that the connection method is simple and convenient for users to operate.

[0059] In another embodiment, the power supply 31 and the charging gun 32 can also be electrically connected to the charging pile 2 independently, that is, the power supply 31 includes a first output terminal 312 for electrically connecting to the power grid; the charging pile 2 includes a second input terminal 21 and a second output terminal 22, and the second input terminal 21 and the second output terminal 22 can be electrically connected to the first output terminal 312 and the charging gun 32 respectively.

[0060] like Figures 5 to 7 As shown, the power supply 31 also includes a first connector 313, the first input end 311 and the first output end 312 are both provided at the first connector 313, the charging pile 2 includes a second connector 23 that can be connected to the first connector 313, and the second input end 21 and the second output end 22 are both provided at the second connector 23. After the charging pile 2 moves to the corresponding second track 12, the first connector 313 of the corresponding power supply 31 is connected to the second connector 23 of the charging pile 2, so that the first output end 312 and the first input end 311 can be connected to the second input end 21 and the second output end 22 respectively, so that the connection method between the charging pile 2 and the charging component 3 is simpler and convenient for user operation.

[0061] like Figure 6As shown, in one embodiment, the second connector 23 is disposed on the main body 24 and can be extended relative to the main body 24. After the charging pile 2 moves into place on the corresponding second track 12, the second connector 23 can be aligned with the first connector 313, and the second connector 23 is controlled to extend toward the first connector 313 and dock with the first connector 313; after charging is completed, the second connector 23 is controlled to retract into the main body 24, so that the second connector 23 is separated from the first connector 313. In this way, the second connector 23 can be docked or separated from the first connector 313 by controlling the second connector 23 to extend relative to the main body 24, without the need for the user to manually dock the second connector 23 and the first connector 313, further facilitating user operation.

[0062] like Figure 7 As shown, in another embodiment, the power supply 31 further includes a seat body 314, and the first connector 313 is disposed on the seat body 314 and can be extended relative to the seat body 314. After the charging pile 2 moves to the corresponding second track 12, the first connector 313 is controlled to extend toward the second connector 23 and dock with the second connector 23; after charging is completed, the first connector 313 is controlled to retract into the seat body 314, so that the first connector 313 is separated from the second connector 23. Alternatively, after the charging pile 2 moves to the corresponding second track 12, the first connector 313 can be controlled to extend toward the second connector 23, and the second connector 23 can be controlled to extend toward the first connector 313, so that the first connector 313 is docked with the second connector 23; after charging is completed, the first connector 313 is controlled to retract into the seat body 314, and the second connector 23 is controlled to retract into the main body 24, so that the first connector 313 is separated from the second connector 23. Of course, in other embodiments, the user can also manually dock the first connector 313 with the second connector 23 through a cable.

[0063] like Figure 1 As shown, the embodiment of the utility model also provides a charging system, including a controller (not shown) and the above-mentioned charging device, and the controller is used to control the movement of the charging pile 2. When the new energy vehicle is parked in the parking space and needs to be charged, the controller controls the charging pile 2 to move along the first track 11 and the second track 12 corresponding to the parking space to the end of the second track 12 away from the first track 11. When the charging pile 2 and the charging component 3 are electrically connected through the telescopic connection of the first connector 313 or the second connector 23, the controller can also control the second connector 23 to telescope relative to the main body 24, or control the first connector 313 to telescope relative to the seat 314, so that the first connector 313 is connected or disconnected with the second connector 23. In this way, the charging system is more intelligent and easy to operate.
