As a new energy source, lithium-ion batteries have the advantages of high energy density and power density, high operating voltage, light weight, small size, long cycle life, high stability, cleanliness, and environmental protection. They have great prospects in the power supply of AGV batteries and other aspects.

[0003] The AGV industry also widely uses unmanned automatic charging, leading to the development of charging baseplates, a connection method that facilitates self-alignment of AGVs. However, due to the structural characteristics of this connection method, there is a risk of sparks in the charging area, necessitating the establishment of dedicated charging areas. This reduces user space utilization and poses safety risks. Furthermore, the output and receiving ends of the charging baseplates require precise docking, reducing the flexibility of battery power transmission.

[0004] Therefore, it is very necessary to develop a wireless charging power battery box with strong heat dissipation and reasonable layout. Utility Model Content

At the same time, a heat dissipation groove is provided to dissipate heat for the wireless vehicle end, thereby improving the heat dissipation capacity of the battery.

[0008] Furthermore, an aluminum plate frame is provided on one side of the outer surface of the battery box, an aluminum plate is fixedly mounted on the aluminum plate frame, the receiving coil is fixedly mounted on the aluminum plate, the aluminum plate is provided with a wire hole, and the receiving coil is connected to the internal components of the battery box through the wire hole.

[0010] Furthermore, the wireless vehicle-end module is provided with a heat sink, and a sealing plate is installed on the wireless vehicle-end module to form a ventilation slot, the ventilation slot is communicated with the air outlet, and the cooling fan discharges the heat of the wireless vehicle-end module from the ventilation slot.

[0011] Based on the above, the sealing plate has the function of guiding the wind direction, and can guide the airflow blown out by the cooling fan to be blown out from the air outlet, thereby accelerating the heat dissipation efficiency and improving the heat dissipation performance.

[0012] Furthermore, a box cover is provided on one side of the battery box body, countersunk threaded holes are provided around the box cover, and the box cover is fixed to the battery box body by countersunk screws.

[0013] Based on the above, the box cover facilitates the replacement of the battery module and the maintenance of the components inside the battery box.

[0016] Furthermore, a connection panel connected to peripheral electrical equipment is provided at the upper end of the battery box, and a Ruima plug and a communication interface are provided on the connection panel.

[0017] Based on the above, the connection panel is installed and connected, and the Ruima plug is used to output power to the AGV car.

[0018] Furthermore, a partition is provided between the battery placement groove and the heat dissipation groove, and the partition is provided with a gap for connecting the battery placement groove and the heat dissipation groove.

[0019] Based on the above, the partition separates the battery placement slot from the heat dissipation slot to prevent the heat of the battery placement slot from affecting the battery module. The wireless vehicle-end module on the battery placement slot is connected to the battery module through the gap using a cable.

[0020] Furthermore, a fixed support plate is provided in the battery placement slot, and the battery cell module is fixedly mounted on the fixed support plate.

[0021] Based on the above, the fixed support frame is used to limit and fix the battery cell module, and at the same time strengthens the internal structure of the battery box.

[0022] Furthermore, the air inlet and the air outlet are both provided with a woven dustproof net.

[0023] Based on the above, the woven dustproof net can prevent large particles of dust from entering the battery box, reducing the impact of large particles of dust on the interior of the battery.

DETAILED DESCRIPTION

[0030] like Figures 1 to 4The figure shows a wireless charging power battery box, including a battery box body 1, which is provided with a battery placement slot 2 and a heat dissipation slot 3. A partition 21 is provided between the battery placement slot 2 and the heat dissipation slot 3, leaving a gap 22. The battery placement slot 2 is provided with a fixed support plate 24, which is provided with a plurality of threaded holes. The battery cell module 9 is fixedly mounted on the fixed support plate 24 by screws engaging the threaded holes. The heat dissipation slot 3 is provided with an air inlet 5 and an air outlet 6. The air inlet 5 and the air outlet 6 are both provided with a woven dustproof net 23 to prevent large particles of dust from entering the battery box body 1 and interfering with the components inside. A wireless vehicle-side module 7 is also fixedly mounted within the heat dissipation slot 3. The wireless vehicle-side module 7 is equipped with a heat sink 13 and a cooling fan 8. A sealing plate 14 is also mounted on the wireless vehicle-side module 7, forming a ventilation slot 15 with the battery case 1. The sealing plate 14 serves to direct wind, thereby accelerating heat dissipation efficiency. The ventilation slot 15 communicates with the air outlet 6, and the cooling fan 8 blows heat from the wireless vehicle-side module 7 out of the ventilation slot 15, thereby rapidly dissipating heat. The wireless vehicle-side module 7 is electrically connected to the battery cell module 9 via a cable through the notch 22. A cover 16 is provided on one side of the battery case 1. Countersunk threaded holes 17 are provided around the cover 16. The cover 16 is fixed to the battery case 1 using countersunk screws, so that the screws do not protrude from the surface of the battery case 1 after installation, thereby improving space utilization.

[0031] An aluminum plate frame 10 is provided on one side of the outer surface of the battery box 1. An aluminum plate 11 is fixedly mounted on the aluminum plate frame 10. Both the aluminum plate frame 10 and the aluminum plate 11 are provided with corresponding wire holes. The receiving coil 4 is fixedly mounted on the aluminum plate 11. The receiving coil 4 is connected to the wireless vehicle-end module 7 via a cable passing through the wire hole. The wireless vehicle-end module 7 converts the AC power generated by the receiving coil 4 into DC power and transmits it to the battery cell module 9 of the battery box 1. A connecting plate is provided at the upper end of the battery box 1. A REMA plug 19 and a communication module are provided on the connecting plate. The connecting panel 18 is installed and connected to the AGV trolley. The REMA plug 19 is used to output power to the AGV trolley.

[0032] The specific implementation of this embodiment is as follows: the assembled battery box is installed on the AGV. When the cell module 9 within the battery box 1 needs to be charged, the AGV moves to the wireless charging area for charging. Since the wireless charging process eliminates the risk of sparks and electric shock, safety hazards are reduced. During the charging process, the receiving coil 4 generates AC power and transmits it to the wireless vehicle module 7. The wireless vehicle module 7 converts the AC current into DC power and transmits it to the cell module 9, achieving wireless charging. Both the receiving coil 4 and the wireless vehicle module 7 generate a large amount of heat during the charging process. The heat from the receiving coil 4 is dissipated through the aluminum plate 11, while the wireless vehicle module 7 uses the cooling fan 8 to blow the heat out of the vents. The heat sink 13 of the wireless vehicle module 7 accelerates heat dissipation, improving the overall heat dissipation performance of the battery box. The wireless charging system does not require precise alignment between the transmitter and receiver, and allows for large offsets, which provides a high degree of transmission freedom.
