[0036] Example 1

[0037] A multi-motor drive circuit includes a first circuit board 1, multiple second circuit boards 2, and multiple motors 3;

[0038] The first circuit board 1 is provided with a power port 101 and a plurality of drive circuits 102. The input ends of the plurality of drive circuits 102 are electrically connected to the power port 101 respectively. The output ends of the drive circuits 102 include a forward interface 1021 and a reverse interface 1022.

[0039] Each second circuit board 2 is electrically connected to one of the drive circuits 102 , and an input end of the second circuit board 2 is electrically connected to the forward interface 1021 or the reverse interface 1022 via a first connecting line.

[0040] The motor 3 is electrically connected to the output end of the second circuit board 2 via a second connecting line;

[0041] When the input end of the second circuit board 2 is electrically connected to the forward rotation interface 1021 of the drive circuit 102, the motor 3 rotates forward; when the input end of the second circuit board 2 is electrically connected to the reverse rotation interface 1022 of the drive circuit 102, the motor 3 rotates reversely.

[0042] Furthermore, the input end of the second circuit board 2 is provided with an input interface 201;

[0043] The first end of the first connecting line is inserted into the input end of the second circuit board 2 , and the second end of the first connecting line is inserted into the forward interface 1021 or the reverse interface 1022 .

[0044] Furthermore, the first end of the first connecting wire is connected to the motor 3 , and the second end of the second connecting wire is welded to the output end of the second circuit board 2 .

[0045] In this embodiment, the power port 101 on the first circuit board 1 is an external power supply that provides power to multiple drive circuits 102, wherein each drive circuit 102 is connected to a second circuit board 2, and the number of second circuit boards 2 is equal to or less than the number of drive power supplies; the output end of the second circuit board 2 is connected to the motor 3, and the input end of the second circuit board 2 is connected to the forward interface 1021 or the reverse interface 1022 of the drive circuit 102 through a first connecting line. When the motor 3 is required to rotate forward, the first connecting line is connected to the forward interface 1021. At this time, after the motor 3 is powered on, the motor 3 will rotate forward; when the motor 3 is required to reverse, the first connecting line is connected to the reverse interface 1022. At this time, after the motor 3 is powered on, the motor 3 will reverse.

[0046] Example 2

[0047] The cargo lane device includes a mounting base 4, wherein a plurality of partitions 5 are provided in the mounting base 4, and a cargo lane is formed between two adjacent partitions 5 and the side panels of the mounting base 4 and the adjacent partitions 5; each cargo lane is provided with a pushing mechanism, which is used to push the goods on the cargo lane, and the pushing mechanism includes a gear box 6 installed at the rear of the mounting base 4, and also includes the multi-motor drive circuit described in Example 1; wherein,

[0048] The first circuit board 1 is mounted on the mounting seat 4;

[0049] The second circuit board 2 and the motor 3 are installed in the gear box 6 .

[0050] In this embodiment, the first circuit board 1 is mounted on the mounting base 4. At the same time, the forward rotation interface 1021 and the reverse rotation interface 1022 are located on the first circuit board 1. When the motor 3 needs to switch the direction of rotation, the merchant can easily switch the direction of the motor 3. It is understandable that in the prior art, the forward rotation interface 1021 and the reverse rotation interface 1022 are located on the back of the gear box 6, and the gear box 6 is located on the inner back of the entire vending machine. When the merchant changes the interface of the motor 3, the forward rotation interface 1021 and the reverse rotation interface 1022 are blocked by the gear box 6, and the merchant cannot directly visually see the forward rotation interface 1021 and the reverse rotation interface 1022. In addition, the space between the back of the gear box 6 and the vending machine cabinet is very narrow. Therefore, when the interface of the motor 3 needs to be changed, the entire aisle device usually needs to be disassembled from the vending machine, which is very inconvenient. In this embodiment, since the forward rotation interface 1021 and the reverse rotation interface 1022 are located at the upper end of the first circuit board 1, merchants can directly see the forward rotation interface 1021 and the reverse rotation interface 1022. At the same time, the upper ends of the forward rotation interface 1021 and the reverse rotation interface 1022 have a large space, which is convenient for merchants to switch the interface of the motor 3. It should be noted that the cargo channel device also includes a conveying spring 8, which is connected to the output end of the motor 3. The forward and reverse rotation of the motor 3 are related to the direction of the conveying spring 8. When the conveying spring 8 is left-handed, the motor 3 rotates forward, and when the conveying spring 8 is right-handed, the motor 3 reverses. Merchants may replace the conveying spring 8 with a different rotation direction according to actual conditions. In this case, the direction of rotation of the motor 3 needs to be changed accordingly; for example, some goods require two adjacent conveying springs 8 to be conveyed at the same time. In this case, one of the conveying springs 8 needs to be left-handed and the other conveying spring 8 needs to be left-handed.

[0051] Furthermore, a wiring port 601 is provided on the gear box 6 , and the input end of the second circuit board 2 faces the wiring port 601 .

[0052] Furthermore, the cargo channel device further includes a fixing member 7 , a plurality of the gear boxes 6 are sequentially installed between the mounting seat 4 and the fixing member 7 , and the first circuit board 1 is installed on the fixing member 7 .

[0053] Furthermore, a plurality of wire hanging portions 701 are provided on the side wall of the fixing member 7 , and a wire hanging area with an upward opening is formed between the wire hanging portions 701 and the side wall of the fixing member 7 , and the first connecting wire is hung in the wire hanging area.

[0054] In this embodiment, the middle portion of the first connecting wire is hung on the wire hanging portion 701, which not only prevents a large number of first connecting wires from being entangled with each other but also improves appearance.

[0055] Furthermore, the fixing member 7 is provided with a plurality of wire-binding portions 702 , and the first connecting wire is bound to the wire-binding portions 702 by wire-binding tapes.

[0056] In this embodiment, the first connecting wires are tied to the wire binding portion 702 by a wire binding tape. Like the previous solution, this is to prevent a large number of first connecting wires from being entangled with each other and is aesthetically pleasing.
