Therefore, the present application is not limited to the embodiments shown, but is consistent with the widest scope of the claims.

[0026] The technical solutions of the present application are described in detail below in conjunction with the embodiments and the accompanying drawings.

[0028] Referring to Figures 1 to 6 illustrated, some embodiments of the present application provide a charging pile swing arm device, comprising: a base 01, the base 01 has an opening 011 at the bottom; a coil spring seat 02, the coil spring seat 02 is provided with a coil spring 021, one end of the coil spring seat 02 provided with the coil spring 021 is embedded into the base 01 through the opening 011 and is fixedly connected with the base 01 in a closed manner; a main shaft 04, a first part of the main shaft 04 is located in the base 01 and is connected with the inner end of the coil spring 021, the main shaft 04 is configured to drive the coil spring 021 to tighten when rotating in a first direction or is driven by the restoring force of the coil spring 021 to rotate in a second direction, a second part of the main shaft 04 extends out of the base 01; a swing arm 03, connected with the second part of the main shaft 04, the swing arm 03 drives the main shaft 04 to rotate in the first direction when swinging in the first direction or drives the swing arm 03 to swing in the second direction when the main shaft 04 is driven by the restoring force of the coil spring 021 to rotate in the second direction.

[0029] The working process of the charging pile swing arm device is as follows: when the charging gun is not used, because the coil spring 021 is provided with an initial pre-tightening force, specifically, because the coil spring 021 is provided with an initial pre-tightening torque, the swing arm 03 with the free end hanging the gun wire is limited in the initial position defined by the positioning block or the buffer block by the initial pre-tightening torque. When the user uses the charging gun, because the gun wire of the charging gun is connected with the swing arm 03 of the charging pile swing arm device, the swing arm 03 is swung when the charging gun is used, thereby driving the main shaft 04 to rotate and further driving the coil spring 021 to tighten. After the use of the charging gun is completed, the coil spring 021 is loosened under the action of the pre-tightening force, thereby driving the main shaft 04 to rotate and further driving the swing arm 03 to swing, so as to realize the automatic reset of the swing arm 03.

[0030] Referring to Figure 4 illustrated, in the conventional scheme, the coil spring is loaded from the top of the base, is closed through the cover plate, and then the swing arm support is arranged on the cover plate, which results in that the top structure of the base is complex, the parts are complex, the cost is high, and the overall structure height is high. In the technical scheme of the present application, the base 01 has a receiving cavity, the receiving cavity is provided with an opening 011 at the bottom, the coil spring seat 02 and the coil spring 021 are embedded into the base 01 from the opening 011, and therefore the top of the base 01 can be integrally closed, and the top structure of the base 01 is simplified.

[0031] Referring to Figure 4 illustrated, in some embodiments of the present application, the side wall of the opening 011 is provided with a mounting ring 012, and a plurality of first mounting holes 013 are arranged on the mounting ring 012. Referring to Figure 5As shown, the periphery of the coil spring seat 02 is provided with a plurality of second mounting holes 022 corresponding to the plurality of first mounting holes 013. The coil spring seat 02 is fixedly connected to the base 01 by the plurality of first mounting holes 013 and the plurality of second mounting holes 022 using bolts. The size of the coil spring seat 02 is designed to be just embedded in the opening 011.

[0032] In some embodiments of the present application, the number of the plurality of first mounting holes 013 and the plurality of second mounting holes 022 can be arbitrarily set, for example, 3 to 6. The plurality of first mounting holes 013 and the plurality of second mounting holes 022 determine the minimum gear of the pre-tightening force of the coil spring 021 when the coil spring seat 02 rotates. When installing the coil spring seat 02, the pre-tightening force of the coil spring 021 can be adjusted by rotating the coil spring seat 02 clockwise or counterclockwise. The minimum angle of rotation is the included angle between two adjacent first mounting holes 013, that is, the minimum gear of the pre-tightening force of the coil spring 021.
