[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-5 The utility model discloses a power connection mechanism for a mobile charging pile, which is used for connecting a charging cabinet 1 arranged on a track 01, and includes:

[0033] A charging seat 2, wherein the charging seat 2 is multiple and arranged on the side of the track 01 along the length direction of the track 01;

[0034] The charging cabinet 1 is provided with a charging gun 11 and a connecting mechanism 12;

[0035] The connection mechanism 12 includes an extension component 121 and a connection probe 122 for connecting with the charging base 2;

[0036] The extension component 121 is used to drive the connection probe 122 to extend outside the charging cabinet 1 and connect with the charging base 2 .

[0037] Through the above-mentioned structural setting, when the charging cabinet 1 is moved to the designated charging base 2, the connecting probe 122 can be pushed out through the extension component 121 arranged inside it, and inserted into the charging base 2 to achieve the power supply effect. It should be noted that the connecting probe 122 is electrically connected to the charging gun 11 to achieve the power supply effect.

[0038] In the present application, another embodiment that needs to be explained is that in order to solve the problem of rainwater erosion and leakage at the power connection of the charging stand, the charging stand 2 includes an insulating shell 21, an input socket 22 arranged inside the insulating shell 21, and a protective cover 23 arranged on the insulating shell 21;

[0039] A conductive plate 221 is disposed on one side of the input socket 22 opposite to the charging cabinet 1 .

[0040] The protective cover 23 is permanently closed on the front of the conductive plate 221 to form a sealed structure to prevent rainwater erosion and leakage.

[0041] It is easy to imagine that the charging cabinet 1 is provided with a driving unit 14, and the driving unit 14 is used to drive the charging cabinet 1 to move along the track 01.

[0042] In another embodiment, the protective cover 23 needs to be opened and closed manually when in use to facilitate the connection of the connection probe 122, which is inconvenient in actual use. Therefore, the protective cover 23 is slidably disposed on the insulating shell 21.

[0043] The protective cover 23 is provided with an electromagnetic component 24;

[0044] The insulating shell 21 is provided with a reset member 25 acting on the protective cover 23;

[0045] The charging cabinet 1 is provided with a permanent magnet 15 corresponding to the electromagnetic component 24. Figure 2 As shown, the permanent magnet 15 and the electromagnetic component 24 are arranged at the same horizontal height, and the permanent magnet 15 is arranged on both sides of the charging cabinet 1. The permanent magnet 15 is used to absorb the electromagnetic component 24 to drive the protective cover 23 to slide open as the charging cabinet 1 moves.

[0046] With the above-mentioned structural arrangement, when the device is in use, as the charging cabinet 1 moves, the permanent magnet 15 arranged thereon, when corresponding to the electromagnetic component 24, can adsorb and drive the protective cover 23 to open synchronously with the charging cabinet 1 in the moving direction of the charging cabinet 1 through the action of magnetic force, thereby facilitating the subsequent connection probe 122 to extend into the interior of the charging seat 2 and contact and energize with the conductive plate 221, until the charging cabinet 1 is charged, the charging cabinet 1 and the charging seat 2 are misaligned, and after the permanent magnet 15 is misaligned with the electromagnetic component 24 and loses its adsorption force, the reset member 25 drives the protective cover 23 to close.

[0047] It should be noted that when the charging cabinet 1 is moving, in order to prevent the protective covers 23 in each charging seat 2 from being adsorbed and opened, the elastic force of the reset member 25 is smaller than the adsorption force between the electromagnetic component 24 and the permanent magnet 15 when the electromagnetic component 24 is energized, and the elastic force of the reset member 25 is smaller than the adsorption force between the electromagnetic component 24 and the permanent magnet 15 when the electromagnetic component 24 is not energized.

[0048] When charging is required at a designated parking space, the electromagnetic assembly 24 of the charging seat 2 inside the corresponding parking space can be in a charging state, so that the protective cover 23 can be opened when the charging cabinet 1 is moved.

[0049] It is easy to imagine that the number of the charging seats 2 is consistent with the number of charging parking spaces, and each of the charging seats 2 corresponds one-to-one to each charging parking space.

[0050] Finally, it should be noted that a linear guide rail 13 is further provided in the charging cabinet 1 , and the connecting mechanism 12 is slidably provided on the linear guide rail 13 .

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0053] In addition, "plurality" means two or more.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
