[0021] 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.

[0022] Reference Figures 1 to 3 As shown, a circuit board assembly for a split-type motor in this embodiment includes a first circuit board 11 disposed in a motor housing 1 and a second circuit board 21 disposed in a control housing 2. The second circuit board 21 is the main control board. A power board is also installed in the control housing 2. The power board is connected to external wires, or a lithium battery is installed in the control housing 2. The first circuit board 11 is located below the motor 12 and is electrically connected to the motor 12. Both the first circuit board 11 and the second circuit board 21 are connected to a data interface 13 or a data connector 22. The data interface 13 can be a USB interface or a Type-C interface, etc. The first circuit board 11 can have a data interface 13 or a data connector 22; the second circuit board 21 can have a data interface 13 or a data connector 22.

[0023] When the first circuit board 11 and the second circuit board 21 are directly connected, if the first circuit board 11 has a data interface 13, the second circuit board 21 needs to have a data connector 22; if the first circuit board 11 has a data connector 22, the second circuit board 21 needs to have a data interface 13.

[0024] When the first circuit board 11 and the second circuit board 21 are connected by a communication line, it is not limited whether the first circuit board 11 and the second circuit board 21 have a data connector 22 or a data interface 13; they can be adapted by a communication line.

[0025] Of course, preferably, when the first circuit board 11 and the second circuit board 21 are connected by a communication line, both the first circuit board 11 and the second circuit board 21 have data interfaces 13.

[0026] In this embodiment, when there is one motor box 1 and one control box 2 or two motor boxes 1 and two control boxes 2, a data interface 13 or a data connector 22 is provided on both the motor box 1 and the control box 2.

[0027] When there are two motor boxes 1 and one control box 2, preferably, the control box 2 is provided with two data interfaces 13 or data connectors 22, so that one control box 2 can control the working status of the two motor boxes 1 separately or simultaneously.

[0028] Of course, a one-to-two communication line can also be designed. In this case, only one data interface 13 needs to be set on the control box 2.

[0029] The aforementioned separate structure of motor box 1 and control box 2 does not involve a main and auxiliary unit. The structure of motor box 1 is identical, making processing more convenient.

[0030] The first circuit board 11 is positioned below the motor 12, thereby reducing the space occupied by the motor box 1 in the width direction.

[0031] Reference Figure 1 As shown, in a preferred embodiment, the first circuit board 11 is arranged perpendicularly to the central axis of the motor 12. In this case, the first circuit board 11 is arranged horizontally, so that the central axis of the motor 12 is perpendicular to the first circuit board 11. Compared with the method of arranging the first circuit board 11 vertically, the space occupied by the first circuit board 11 in the vertical direction can be reduced.

[0032] Reference Figure 2 As shown, taking the horizontal arrangement of the first circuit board 11 as an example, there are two ways to connect the data interface 13 or the data connector 22 to the first circuit board 11;

[0033] In one embodiment, the data interface 13 or data connector 22 is electrically connected to the first circuit board 11 and arranged parallel to each other. Preferably, the first circuit board 11 is electrically connected to the data interface 13 and arranged parallel to each other.

[0034] The data interface 13 is also set horizontally, which can reduce the vertical space occupied by the data interface 13 and further reduce the overall height of the motor box 1.

[0035] Reference Figure 1 As shown, a third circuit board 23 is connected between the second circuit board 21 and the data interface 13 or data connector 22. The third circuit board 23 is vertically arranged with the second circuit board 21. In the above scheme, in order to adapt to the horizontal setting of the data interface 13 on the first circuit board 11, a data connector 22 needs to be set on the second circuit board 21, and the data connector 22 is also horizontally arranged.

[0036] Furthermore, the control box 2 is located below the motor box 1. In order to reduce the space occupied in the width direction, the second circuit board 21 is usually set vertically. At this time, the third circuit board 23 is needed to provide a transition so that the data connector 22 can be set horizontally.

[0037] Reference Figure 3 As shown, in the second scheme, the data interface 13 or data connector 22 is electrically connected to the first circuit board 11 and is arranged perpendicular to each other. Preferably, the data interface 13 is electrically connected to the first circuit board 11 and is arranged perpendicular to each other.

[0038] The data interface 13 is arranged vertically, so that the data interface 13 on the motor box 1 and the data connector 22 on the control box 2 can be plugged in vertically; this facilitates the design of the snap-fit ​​structure between the motor box 1 and the control box 2.

[0039] The second circuit board 21 is electrically connected to the data connector 22 or the data interface 13, and the two are arranged parallel to each other. Since the control box 2 is located below the motor box 1, the second circuit board 21 is arranged vertically. The data connector 22 is directly electrically connected to the second circuit board 21 and is also arranged vertically, so that it can be plugged into the data interface 13 on the first circuit board 11 in the vertical direction.

[0040] The second circuit board 21 is connected to a data transmission interface 24, which can be a USB interface or a Type-C interface.

[0041] The data transmission interface 24 can be located at the end of the control box 2 away from the motor box 1, or on the side of the control box 2;

[0042] When there are two motor boxes 1 and one control box 2, and the control box 2 is plugged into one of the motor boxes 1, that is, when the data interface 13 on one motor box 1 is plugged into the data connector 22 on the control box 2, it can be connected to the output interface of the other motor box 1 through the data transmission interface 24 via a transmission line, thereby enabling a single control box 2 to control two motor boxes 1.

[0043] The second circuit board 21 is connected to an RS485 interface 25, which is used to connect to the 485 bus.

[0044] In one embodiment, the control box 2 and the data connector 22 and data interface 13 on one of the motor boxes 1 are directly plugged into each other, so that the control box 2 and the motor box 1 are in contact; the first circuit board 11 is provided with the data interface 13, and the second circuit board 21 is provided with the data connector 22, and the data interface 13 and the data connector 22 are plugged into each other. Of course, it is also possible that the first circuit board 11 is provided with the data connector 22, and the second circuit board 21 is provided with the data interface 13, and the two are plugged into each other.

[0045] In another embodiment, there is a gap between the motor box 1 and the control box 2. The first circuit board 11 and the second circuit board 21 are connected by a communication line through a data interface 13 or a data connector 22. The two are connected by a communication line. Preferably, this method allows the control box 2 and the motor box 1 to be electrically connected to the data interface 13, and the two ends of the communication line are connected to the data connector 22.

[0046] This connection method eliminates the need for a locking structure between the motor box 1 and the control box 2, saving the space required for designing a locking structure.

[0047] 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.
