[0023] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As Figures 1-5 shown, a wireless charging carrier vehicle includes a carrier vehicle body 1 with a built-in drive unit. The carrier vehicle body 1 is equipped with a charging pile 2, and a wireless charging component 3 is arranged between the carrier vehicle body 1 and the charging pile 2. The carrier vehicle body 1 only needs to move near the charging pile 2 and can be charged without contact. The wireless charging component 3 includes a transmitting host 4 installed on the charging pile 2 and connected to a power source. The transmitting host 4 is connected to a transmitting coil 41. The rated power of the charging pile 2 is 350W, its input voltage is 220V ± 15%, the frequency is 50Hz, and the input current is 2.0A. A receiving host 5, a receiving coil 51 connected to the receiving host 5, and a battery pack 52 are installed on the carrier vehicle body 1. Insulating components 6 are respectively provided for the transmitting coil 41 and the receiving coil 51. The charging voltage of the receiving host 5 is 29.4V ± 0.2V, the output current is 10A ± 5%, and the output type is constant current - constant voltage.

[0025] Specifically, the insulating component 6 includes insulating plates 61 fixed to the side surfaces of the carrier vehicle body 1 and the charging pile 2. The transmitting coil 41 and the receiving coil 51 are respectively fixedly attached to the insulating plates 61. The insulating plates 61 are usually made of rubber material. On the one hand, it has good insulating performance, and on the other hand, it ensures the installation stability of the transmitting coil 41 and the receiving coil 51.

[0026] Specifically, to provide sufficient installation area, the carrier vehicle body 1 is fixedly attached to the receiver bracket 62 with an L-shaped cross-section by threaded parts, and the receiving coil 51 is fixed on the receiver bracket 62. The height of the receiver bracket 62 is the same as that of the receiving coil 51, and the insulating plate 61 is attached to the receiver bracket 62.

[0027] Furthermore, the operating temperature of the battery pack 52 is -20 - 55°C, the storage temperature is -20 - 55°C, and its protection temperature is 85°C. Specifically, a lithium battery 53 is selected. Inside the carrier vehicle body 1, there is a battery rack 54 for the vertical insertion of the lithium battery 53. The lithium battery 53 is encapsulated in an insulating housing 55, and a lifting handle 56 is provided at the top of the insulating housing 55. This sliding and pulling structure facilitates the quick plugging and replacement of the lithium battery 53.

[0028] Even further, a wired charging interface 57 is provided on the battery pack 52, and a protective cover plate 58 covering the battery pack 52 is provided outside the carrier vehicle body 1. The protective cover plate 58 can be opened in a necessary state. At this time, the wired charging interface 57 is exposed and charged by a charging cable.

[0029] Meanwhile, the size of the receiving host 5 is 122.0 * 122.0 * 30.0 mm, and the total weight is 0.32 Kg. It is connected with a 485 bus 7 and a 2.4G antenna 71 for internal and external communication. The size of the transmitting host 4 is 203 * 147 * 77.8 mm, and the total weight is 1.38 Kg.

[0030] Visibly, a cooling fan 42 is installed on the transmitting coil 41, and a heat dissipation aluminum plate 43 is installed on the back of the receiving coil 51. The heat dissipation aluminum plate 43 is fixed on the carrier vehicle body 1 for passive heat dissipation, and heat dissipation ribs are usually provided on its surface to further increase the heat dissipation area.

[0031] Obviously, the transmitting coil 41 and the receiving coil 51 are equipped with a pairing module 8, and a charging overvoltage protection module 81 and a charging overcurrent protection module 82 are provided between the receiving host 5 and the battery pack 52. When the charging distance between the transmitting coil 41 and the receiving coil 51 is within 20 - 40 mm, the allowable offset distance in the horizontal and vertical directions is 20 mm.

[0033] In summary, the principle of this embodiment is as follows: When the power plug of the transmitting host 4 is connected to a single-phase 220V power socket and the indicator light shows the standby state, the transmitting host 4 continuously emits electromagnetic waves. When the receiving coil 51 of the forklift truck body 1 enters the induction range of the transmitting coil 41, the receiving coil 51 receives the electromagnetic waves and converts them into current to supply power to the receiving host 5. Then, after the receiving host 5 successfully communicates with the transmitting host 4, wireless charging of the vehicle can be achieved. After the communication pairing between the transmitter and the receiver is completed, the transmitting host 4 converts the 220V single-phase power into electrical energy, and the transmitting coil 41 transmits the electrical energy to the receiving coil 51 through electromagnetic induction. The receiving coil 51 transmits the received electrical energy to the receiving host 5, and the receiving host 5 converts the electromagnetic waves into current to charge the battery pack 52. When the communication pairing is completed, the receiving host 5 will output a charging current according to the detected state of the battery pack 52. If it detects that the battery pack 52 is power-starved, it will charge with a small current to activate the battery pack 52 and then charge normally.
