DETAILED DESCRIPTION

[0053] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0054] Please also see Figure 1-Figure 7 , the present application provides some embodiments of a contactless power supply track.

[0055] like Figure 1 , Figure 2 , Figure 3 As shown, the contactless power supply track of the present application comprises: a guide rail 1, a first bracket 11, a second bracket 12 and a positioning member 13. The first bracket 11 and the second bracket 12 are arranged at intervals on the guide rail 1 and are used to install the contactless power supply cable; the positioning member 13 is connected to the guide rail 1 and is located between the first bracket 11 and the second bracket 12; the cable and the positioning member 13 both extend along the length direction of the guide rail 1.

[0056] Specifically, the guide rail 1 refers to a member that plays a guiding role. The contactless power supply track is applied to the contactless power supply system. The guide rail 1 guides the contactless power supply transport vehicle in the contactless power supply system. The bracket refers to a member that plays a supporting role. The first bracket 11 and the second bracket 12 are used to install and support cables. The cable refers to a cable used for power supply. The cable includes a first cable 111 and a second cable 121. The first bracket 11 supports the first cable 111, and the second bracket 12 supports the second cable 121. There is a gap between the first bracket 11 and the second bracket 12, so that there is a gap between the first cable 111 and the second cable 121. The positioning member 13 refers to a member used for positioning, which specifically assists in positioning the mobile position of the contactless power supply transport vehicle. In this application, the cable used for power supply is installed on the first bracket 11 and the second bracket 12 respectively, and the positioning member 13 is assembled between the first bracket 11 and the second bracket 12, so that the cable, the first bracket 11, the second bracket 12 and the positioning member 13 are more compact and not bloated.

[0057] The length direction of the guide rail 1 is the moving direction of the contactless power supply transport vehicle. Since the cable and the positioning member 13 both extend along the length direction of the guide rail 1, as the contactless power supply transport vehicle moves, the cable can always provide contactless power to the contactless power supply transport vehicle, and the positioning member 13 can position the contactless power supply transport vehicle. The contactless power supply transport vehicle includes: a contactless power supply 21 and a positioning sensor 22. The contactless power supply 21 is located between the first bracket 11 and the second bracket 12, that is, between the first cable 111 and the second cable 121. There is a gap between the contactless power supply 21 and the cable (the first cable 111 and the second cable 121) and there is no contact. The cable provides an alternating current and forms a magnetic field, which generates an induced current in the contactless power supply 21, thereby realizing contactless power collection. The positioning sensor 22 senses the positioning member 13 to achieve positioning.

[0058] The cable is electrically connected to the power cabinet, which refers to a component that provides electrical energy. The power cabinet can provide high-frequency alternating current. For example, the industrial frequency 380V alternating current is transmitted to the cable after filtering, rectification, inversion and compensation.

There may be one or more third brackets 14. When multiple third brackets 14 are used, the multiple third brackets 14 are arranged along the length direction of the guide rail 1. The third bracket 14 is located on the side of the second bracket 12 away from the first bracket 11. A gap is formed between the third bracket 14 and the second bracket 12. The communication cable 141 is installed on the third bracket 14 to facilitate the control of the movement of the contactless power supply transport vehicle, and the first bracket 11, the second bracket 12, the third bracket 14 and the positioning member 13 are all concentrated together, and the structure is more compact.
