Technical Field

[0001] The present application relates to the field of mobile charging systems for electric vehicles, and specifically to track-type charging systems. Background Art

[0002] With the widespread use of new energy vehicles, the problem of difficulty in charging electric vehicles has gradually emerged. At present, electric vehicle charging in parking lots is divided into charging areas, which are managed by dedicated personnel or only allow charging vehicles to enter. This squeezes out the parking space for gasoline vehicles and wastes a lot of parking resources. Especially when it is difficult to park in the gasoline parking area, it is easy to cause conflicts. Therefore, a charging system that can cover a larger area of ​​the parking lot and avoid installing too many charging devices is needed. Summary of the invention

[0003] The purpose of this application is to provide a track-type charging system, which solves the problem that the charging device can only be fixed on the parking space and cannot meet the charging needs of electric vehicles. It can cover the entire parking lot and save renovation costs.

[0004] In order to achieve the above purpose, this application is implemented through the following technical solutions:

[0005] A track-type charging system comprises a main track, wherein the main track is a concave hanging track, a through groove is provided at the bottom of the main track, a plurality of sub-tracks are provided on the main track, the sub-tracks are also concave hanging rails, a through groove is provided at the bottom of the sub-tracks, and the through grooves of the sub-tracks are connected with the through grooves of the main track; a plurality of mobile charging vehicles are provided on the main track, and the mobile charging vehicles comprise a vehicle body, a magnetic suction block and a power-taking end are provided on the side wall of the vehicle body, a fixing plate is provided at one end of the sub-track away from the main track, a first telescopic rod is provided on the fixing plate, an electromagnet is fixed at the end of the first telescopic rod, and a power-receiving end is also provided on the fixing plate; a connecting rod is provided at the bottom of the vehicle body, the connecting rod passes through the through groove and is connected to an electric drum, the electric drum comprises a skeleton, a winding rod, and a first motor, the first motor is fixed on the skeleton, the output shaft of the first motor is connected to the winding rod, the winding rod is rotatably connected to the skeleton, a charging wire is wound on the winding rod, a charging gun is provided on the charging wire, and the first motor drives the winding rod to rotate to realize the retraction and extension of the charging gun.

[0006] Furthermore, four wheels are provided at the bottom of the vehicle body, a power supply and a second motor are provided on the mobile charging vehicle, the second motor drives the wheels to rotate, and two sliders are also provided at the bottom of the vehicle body, the sliders are inverted concave blocks, and a second telescopic rod is provided on the vehicle body, the second telescopic rod drives the sliders to move up and down; a groove perpendicular to the main through groove is provided on the main track, a slide rail is provided in the groove, the sub-track has a groove parallel to the main track groove, a slide rail is also provided in the sub-track groove, and the main track slide rail is connected to the sub-track slide rail; when the second telescopic rod is retracted, the slider is located above the slide rail, and when the second telescopic rod is extended, the slider contacts the slide rail and causes the wheel to leave the main track.

[0007] Furthermore, the power-taking end is a truncated cone-shaped power-taking hole, and the power-connecting end is a power-connecting pole with a truncated cone-shaped end.

[0010] Compared with the prior art, the beneficial effects of this application are:

[0011] Existing charging devices are all fixed on parking spaces, and electric vehicles can only be charged in a few designated parking spaces. However, due to the shortage of parking resources, cars that do not need to be charged are often parked in parking spaces with charging devices, resulting in electric vehicles that need to be charged being unable to charge. If charging devices are installed in all parking lots, it will cause waste and increase costs.

[0012] The present application sets a main track and a sub-track above the parking lot. The main track is mainly used for the movement of mobile charging vehicles. The sub-track is set above the corresponding parking space for the mobile charging vehicles to stop when charging to avoid blocking the main track. By deploying a few mobile charging vehicles, full coverage of the parking lot can be achieved, which not only saves costs but also makes good use of the resources of the parking lot.

[0013] Furthermore, the electric drum of the present application can automatically realize the retraction and extension of the charging gun, which is convenient for automated management and prevents the charging gun from being dragged. BRIEF DESCRIPTION OF THE DRAWINGS

The main track 1 is provided with a groove 23 perpendicular to the main through groove 2, and a slide rail 24 is provided in the groove 23. The sub-track 3 is parallel to the groove 23 of the main track 1, and a slide rail 24 is also provided in the groove 23 of the sub-track 3. The slide rail 24 of the main track 1 is connected with the slide rail 24 of the sub-track 3. When the second telescopic rod 22 is retracted, the slider 21 is located above the slide rail 24. When the second telescopic rod 22 is extended, the slider 21 contacts the slide rail 24 and causes the wheel 20 to detach from the main track 1. When the slider 21 contacts the slider 21, the wheel 20 detaches from the main track 1. In the subsequent dragging process, the friction coefficient between the slide rail 24 and the slider 21 is small, which reduces the friction resistance, prevents the wheel 20 from being damaged, and prolongs the service life.

The winding rod 16 includes a base shaft 27, and a plurality of conductor ring slides 28 are arrayed on the outer side of the base shaft 27. The inner diameter wall and the outer diameter wall of the conductor ring slide 28 are both provided with insulating spacers 29. The conductor ring slide 28 is in contact with a contact piece 4 at one axial end. The end of the contact piece 4 away from the conductor ring slide 28 is connected to a connection wire.
