[0002] At present, when the female plug-in connector provided on the mobile energy vehicle is docked with the male plug-in connector provided on the fixed gun rack frame, the energy vehicle is required to move to a precise position each time. If there is a deviation (i.e., misalignment) between the male plug-in connector and the female plug-in connector, or the positioning accuracy of the energy vehicle is poor, the male plug-in connector and the female plug-in connector will fail to dock.

[0003] In the process of aligning the male plug with the female plug, there are X-axis displacement, Y-axis displacement, and angle errors with the X-axis or Y-axis. Due to the large errors, the common treatment method is: sliding floating structure of X-axis and Y-axis, and adding elastic rubber columns on this basis, to achieve the purpose of angle adjustment by changing the spring tension at the four corners. However, this method is only suitable for small angle deflection adjustment (generally ±8°), and cannot achieve large angle deflection adjustment (±15° deflection adjustment). Summary of the invention

Therefore, by designing that the inner hole 501 is a waist-shaped hole and the inclined surface is a semi-conical surface, compared with the existing rectangular hole design, this method has a simple structure, is easy to operate, and will not get stuck (especially at the short side of the rectangular hole, if the angle is slightly larger, it will easily get stuck). When the first guide 5 contacts the second guide 6, the second guide 6 first contacts the semi-conical surface of the first guide 5, and is driven by the semi-conical surface to move to the center position of the first guide 5.

When the first guide member 5 contacts the second guide member 6, the second guide member 6 first contacts the semi-conical surface of the first guide member 5, and is driven by the semi-conical surface to move to the center position of the first guide member 5. Then, under the action of the torque, the angle between the first guide member 5 and the second guide member 6 is actually made to be 0°, so as to realize a large-angle deflection adjustment of the male plug 4 and the female plug 2.
