[0020] In an embodiment of the utility model, first charging copper sheet 31 and second charging copper sheet 32 can be separated by nylon piece and inlayed at the both sides of the front end of intelligent cart, and the wall of nylon piece charging copper sheet 30 is more prominent, that is, when the front end of intelligent cart contacts other metal objects, the first contact is nylon piece, thereby avoiding the direct contact of charging copper sheet 30 and other metal objects, and the risk of short circuit of intelligent cart can be further reduced.

[0021] In an embodiment of the utility model, first charging contact 41 and second charging contact 42 can be hiddenly installed at the both sides of the rear end of intelligent cart through fixed support, and the installation position of first charging contact 41 corresponds to the position of first charging copper sheet 31, and the installation position of second charging contact 42 corresponds to the position of second charging copper sheet 32, that is, when two intelligent carts are stacked together, the first charging contact 41 of the front cart contacts the first charging copper sheet 31 of the rear cart, and the second charging contact 42 of the front cart contacts the second charging copper sheet 32 of the rear cart.

[0025] In an embodiment of the utility model, second infrared communication module 52 is still used for inquiring the state of the charging battery 10 of the next intelligent trolley charging system of the current intelligent trolley charging system, to judge whether the electric quantity of the charging battery 10 of the next intelligent trolley charging system is below the first preset threshold value, and feedback to first infrared communication module 51.

[0026] Specifically, the first charging control panel 20 can determine whether there is another intelligent trolley behind the current intelligent trolley by acquiring the signal of the microswitch 43 under the first charging contact 41 and the second charging contact 42. For example, the current intelligent trolley (which can be numbered as intelligent trolley 1) is connected to the charging pile through the electric control lock 60. When the first charging control panel 20 in the intelligent trolley 1 detects the signal of the microswitch 43, it can be determined that there is another intelligent trolley (which can be numbered as intelligent trolley 2) behind the intelligent trolley 1. At this time, the intelligent trolley 1 can start the second infrared communication module 52, acquire the state of the charging battery of the intelligent trolley 2 through the first infrared communication module 51 of the intelligent trolley 2, and send the acquired state of the charging battery of the intelligent trolley 2 to the first charging control panel 20 of the intelligent trolley 1.
