Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a motor circuit board mounting module. Background Art

For example, the patent with application number 202123413135.5 discloses a winding module for a linear motor, in which the circuit board of the linear motor is installed on the side of the stator core. This poses the following problem: the core lengths of different linear motors may be different. Therefore, for cores of different lengths, the installation position of the circuit board installed on the side of the core will be difficult to determine. In addition, the circuit board located on the side will occupy the space on the side, which may cause interference with other components of the linear motor during assembly. Utility Model Content

In the utility model, the circuit board is arranged between the two groups of long iron core modules, and the actual length of the long iron core module can be adjusted by adding or reducing the iron core units according to actual needs. However, no matter how the length of the two groups of long iron core modules is, the circuit board is installed in the middle position, so the circuit board can be adapted to the installation of iron cores of different lengths.

[0006] In one embodiment, the main body includes a support block located at the bottom and a winding post connected to the middle upper part of the support block. After the circuit board is installed on the connecting mounting plate, the top height of the circuit board is not higher than the top height of the winding post.

[0007] In the above scheme, the highest point of the core unit is higher than the highest point of the connecting mounting plate, so there is an installation space in height between the two. The circuit board is installed in the installation space, and the structure is compact. The circuit board and the components installed on the circuit board usually do not protrude outside the installation space, so the interference with other components located outside the installation space can be reduced.

[0008] In one embodiment, the circuit board is in a strip shape, and a supporting protrusion matched with the circuit board is provided on the upper portion of the connecting and mounting plate.

[0009] In the above solution, the supporting protrusion is in the shape of a right triangle, and the supporting protrusion provides more supporting area for the installation of the circuit board, so that the circuit board can be stably installed on the two connecting mounting boards.

[0010] In one embodiment, two mounting holes are provided on the connecting mounting plate, and the mounting holes are vertically arranged screw holes, and two through holes are respectively provided at both ends of the circuit board.

[0011] In one embodiment, the connecting protrusion is in a trapezoidal shape, and the shorter parallel sides of the trapezoidal shape are located on the side surfaces of the corresponding main body, and the longer parallel sides of the trapezoidal shape are located on the outer sides of the corresponding main body.

[0012] In the above solution, the trapezoidal shape can achieve the effect of stable connection and no disengagement when the connection protrusion and the connection groove are connected. The connection groove is also a trapezoidal shape.

[0013] In one embodiment, a connection slot adapted to the connection protrusion is provided on one side of the lower portion of the connection mounting plate.

[0014] In the above solution, the trapezoidal shape of the connecting protrusion can achieve a stable connection and prevent disconnection when connected to the connecting slot. The connecting slot is also a trapezoidal shape.
