DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Series mobile charging piles, such as Figure 1 As shown, several charging bases 1 fixed on the ground are connected in series through cables, and the cables can be buried below the ground. Several charging bases 1 are connected to transformers 2 fixed on the wall through cables, and a charging pile cabinet 4 is provided on the ground. The lower end surface of the charging pile cabinet 4 is provided with a pulley, so that the charging pile cabinet 4 can slide on the ground;

[0020] like Figure 1 and Figure 2 As shown, several charging bases 1 are the same, so that a charging pile cabinet 4 can be connected to these several charging bases 1 respectively when moving, and the connecting protrusion 41 provided on the lower end surface of the charging pile cabinet 4 can be placed in the arc groove 11 provided on the upper end surface of the charging base 1;

[0021] like Figure 3 and Figure 4 As shown, the arc-shaped groove 1 on the upper end surface of the charging base 1 is an arc-shaped upward protrusion, and the electromagnetic connection socket 3 is embedded in the side end surface of the arc-shaped groove 1. The connection socket 32 ​​with a hole on the electromagnetic connection socket 3 is fixed in the inner circle of the annular electromagnet 31, and the annular electromagnet 31 is connected to the commutator through the wire at the same time, which is used to change the direction of the current on the annular electromagnet 31, so that the magnetic pole on the annular electromagnet 31 can be changed;

[0022] like Figure 5 and Figure 6 As shown, a cuboid-shaped connecting protrusion 41 is fixedly provided on the lower end surface of the charging pile cabinet 4, and a placement groove 411 is provided on the side end surface of the connecting protrusion 41. A telescopic plug 5 is fixedly provided in the placement groove 411 through a telescopic spring 53. The plug 52 is fixed in the inner circle of the annular permanent magnet 51, and the plug 52 and the annular permanent magnet 51 are fixedly connected to the inner end surface of the placement groove 411 through the telescopic spring 53.

[0023] like Figure 2 , Figure 3 and Figure 6As shown, when the electromagnetic connection socket 3 is located at the left end surface of the arc-shaped groove 11 , the telescopic plug 5 is located at the left end surface of the connecting protrusion 41 , so that the telescopic plug 5 can be inserted into the electromagnetic connection socket 3 .

[0024] Before use, place the charging base 1 Figure 1 As shown, it is fixed on the ground of different parking spaces by fixing bolts, and connected in series with a cable to the transformer 2;

[0025] Then move the charging pile cabinet 4 so that the connecting protrusion 41 on the charging pile cabinet 4 is inserted into the arc-shaped groove 11 of the charging base 1. Since the annular electromagnet 31 on the electromagnetic connection socket 3 has magnetic force, when the magnetic poles of the annular electromagnet 31 are opposite to the magnetic poles of the annular permanent magnet 51 on the telescopic plug 5, according to the principle of opposites attract, the elastic force of the compression spring 53 can be overcome, so that the annular permanent magnet 51 stretches with the plug 52 until it is inserted into the connecting socket 32, so that the charging pile cabinet 4 can be electrically connected to the charging base 1, that is, there is electricity in the charging pile cabinet 4, and then the charger can be charged by connecting the charging socket on the charging pile cabinet 4;

[0026] When the charging pile cabinet 4 needs to be moved, the commutator connected to the annular electromagnet 31 is started to change the direction of the current. At this time, the magnetic poles on the annular electromagnet 31 change. According to the principle of like repels like, there is a large repulsive force between the annular electromagnet 31 and the annular permanent magnet 51. At this time, the annular permanent magnet 51 will retract with the plug 52 into the placement groove 411 of the connecting protrusion 41. At this time, the charging pile cabinet 4 is disconnected from the charging base 1. By pushing the charging pile cabinet 4, you can leave this charging base 1, and then move the charging pile cabinet 4 to the next charging base 1. Repeat the above plug-in steps to connect the charging pile cabinet 4 to the charging base 1, that is, one charging pile cabinet 4 covers multiple parking spaces for charging, which greatly improves the probability of using the charging pile cabinet 4 and reduces the construction cost.

[0027] In the later stage of construction, the number of charging pile cabinets 4 can be appropriately increased according to the utilization probability of the charging base 1 to improve the utilization probability of the charging base 1 .

[0028] In order to ensure the safety of the charging pile cabinet 4 , a sliding track may be provided on the ground to facilitate the stable sliding of the charging pile cabinet 4 .

[0029] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
