Technical Field

[0001] This invention relates to the field of circuit connection, and more particularly to a combined motor circuit board connection structure. Background Technology

[0002] Currently, boost circuits are often used to drive high-power motors. However, using boost circuits inevitably leads to excessive line losses in the circuit. Since low-voltage, high-current discharge cells are available on the market, multiple parallel small motors can be used to work together to increase the overall power of the device.

[0003] In the existing technology, the connection between the power supply (i.e., the battery cell) and multiple motors needs to be connected by wires. In the relatively complex circuit connection, a large number of wires inevitably accumulate inside the equipment, which is not conducive to the overall assembly and production of the device and internal heat dissipation.

The motor positive wiring terminal of each motor is plugged into and electrically connected to the corresponding set of motor positive wiring ports, and the motor negative wiring terminal of each motor is plugged into and electrically connected to the corresponding set of motor negative wiring ports.

[0008] As a preferred technical solution, the circuit board body is provided with a positive copper busbar and a negative copper busbar, and the positive terminal of each motor is located on the positive copper busbar, and the negative terminal of each motor is located on the negative copper busbar.

[0009] As a preferred technical solution, the battery cell wiring device includes a battery cell wiring port provided on the circuit board body, and a battery cell terminal is provided at one end of the power battery cell near the circuit board body, and the battery cell terminal is inserted into the battery cell wiring port accordingly.

[0010] Due to the adoption of the above technical solution, the combined motor circuit board connection structure connects the power supply cell and multiple motors, including a circuit board body. Each motor is plugged into and installed on one side surface of the circuit board body. The motors are connected in parallel and have a motor wiring device between them and the circuit board body. The power supply cell is installed on the other side surface of the circuit board body, and a cell wiring device is provided between the power supply cell and the circuit board body.
