[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Reference Figure 1 and Figure 2 As shown, a circuit board assembly in this embodiment includes a first circuit board 11 disposed in a motor box 1 and a second circuit board 21 disposed in a control box 2, wherein the second circuit board 21 is a main control board and controls the motor 12 in the motor box 1 to work through the first circuit board 11.

[0022] A power board is also installed inside the control box 2. The power board is electrically connected to the second circuit board 21 and is connected to a power cord. Of course, a lithium battery can also be installed inside the control box 2. The first circuit board 11 is located on the side of the motor 12 and is electrically connected to the motor 12. Compared with the solution of placing the first circuit board 11 below the motor 12, the vertical space occupied by the motor box 1 can be reduced, thereby adapting to the installation area with less space in the height direction. Both the first circuit board 11 and the second circuit board 21 are connected to a data interface 13 or a data connector 22.

[0023] The data interface 13 can be a USB interface or a Type-C interface, etc. The first circuit board 11 can have the data interface 13 or the data connector 22; the second circuit board 21 can have the data interface 13 or the data connector 22.

[0024] When the motor box 1 and the control box 2 are directly plugged in, the data interface 13 or data connector 22 on the first circuit board 11 and the second circuit board 21 need to be limited. If the first circuit board 11 is a data interface 13, then the second circuit board 21 is a data connector 22; if the first circuit board 11 is a data connector 22, then the second circuit board 21 is a data interface 13, so as to facilitate direct plugging and unplugging of the motor box 1 and the control box 2.

[0025] When the motor box 1 and the control box 2 are connected by a communication line, there are no restrictions on the data interface 13 or data connector 22 on the first circuit board 11 and the second circuit board 21, and they can be adapted by the communication line.

[0026] Preferably, both the first circuit board 11 and the second circuit board 21 are connected to data interfaces 13, and both ends of the communication line are connected to data connectors 22; so that no connection locking structure is required between the motor box 1 and the control box 2.

[0027] Reference Figure 2 As shown, preferably, the first circuit board 11 is arranged parallel to the central axis of the motor 12. When the output shaft of the motor 12 is arranged vertically, the first circuit board 11 is also arranged vertically. Compared with the first circuit board 11 being arranged horizontally, this reduces the space occupied in the width direction, making the structure more compact.

[0028] In one embodiment, based on the vertical arrangement of the first circuit board 11, the data interface 13 or data connector 22 on the first circuit board 11 is arranged parallel to the first circuit board 11. Preferably, the data interface 13 is connected to the first circuit board 11 and is also arranged vertically. Correspondingly, if the control box 2 and the motor box 1 are directly plugged in, the data connector 22 is connected to the second circuit board 21 and the data connector 22 is arranged parallel to the first circuit board 11.

[0029] There are two possible configurations for the second circuit board 21: one is that the second circuit board 21 is perpendicular to the first circuit board 11; the other is that the second circuit board 21 is parallel to the first circuit board 11.

[0030] Preferably, the second circuit board 21 is arranged parallel to the first circuit board 11, and the data interface 13 or data connector 22 on the second circuit board 21 is arranged parallel to the second circuit board 21, which can prevent the control box 2 from protruding from the motor box 1 in the width direction.

[0031] If the control box 2 and the motor box 1 are connected via a communication cable, then if the data interface 13 is connected on the first circuit board 11, the data interface 13 can also be connected on the second circuit board 21, and then the two circuit boards can be adapted via a communication cable.

[0032] In another embodiment, based on the vertical arrangement of the first circuit board 11, the data interface 13 or data connector 22 on the first circuit board 11 is arranged vertically with the first circuit board 11. Preferably, the data interface 13 is connected to the first circuit board 11 so that the data interface 13 is arranged horizontally. The control box 2 can be arranged on the side of the motor box 1, thereby reducing the vertical space occupied by the motor box 1 and the control box 2 as a whole. The motor box 1 and the control box 2 can be inserted horizontally.

[0033] Of course, a data connector 22 can also be connected to the second circuit board 21, and the two data interfaces 13 can be connected by a communication cable adapter.

[0034] The second circuit board 21 is arranged parallel to the first circuit board 11. At this time, both the second circuit board 21 and the first circuit board 11 are arranged vertically. The data interface 13 or data connector 22 on the second circuit board 21 is arranged vertically to the second circuit board 21. Preferably, if the data interface 13 is connected to the first circuit board 11, then the data connector 22 is connected to the second circuit board 21. The data connector 22 is arranged horizontally, so that it can be horizontally connected to the data interface 13 on the first circuit board 11.

[0035] Alternatively, the arrangement of the second circuit board 21 can be changed so that the second circuit board 21 is set vertically to the first circuit board 11, and the data interface 13 or data connector 22 on the second circuit board 21 is set parallel to the second circuit board 21. In this scheme, the second circuit board 21 is set horizontally, and the data connector 22 on the second circuit board 21 is also set horizontally.

[0036] Reference Figure 2 As shown, the second circuit board 21 is provided with a data transmission interface 23 and / or an RS485 interface 24;

[0037] When there are two motor boxes 1, if there is one control box 2, it can be connected to the data interface 13 or data connector 22 of the other motor box 1 through the data transmission interface 23, and the two are connected through a communication line.

[0038] Of course, in the above situation, the data transmission interface 23 can be omitted, and the two motor boxes 1 can be connected by a communication cable that splits into two. In this case, only one data connector 22 or data connector 22 is needed on the motor box 1.

[0039] RS485 interface 24 can be used to connect to a 485 bus.

[0040] When the motor box 1 and the control box 2 need to be directly connected, preferably, the first circuit board 11 is provided with a data interface 13, and the second circuit board 21 is provided with a data connector 22, which is plugged into the data interface 13.

[0041] When the motor box 1 is not directly connected to the control box 2 and there is a gap between them, preferably, the first circuit board 11 and the second circuit board 21 are connected by a communication line through the data interface 13 or the data connector 22.

[0042] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
