On the mounting section. As a result, the electronic components are distributed in a ring shape on the flexible circuit board and the supporting seat, and further distributed to the wing structure. In addition, according to the number of electronic components and the configuration position of the controller, the number of flexible circuit boards and supporting seats can also be adjusted to multiple according to demand, and each electronic component of the multiple flexible circuit boards after assembly is preferably Do not overlap each other. Thereby, the flexible circuit board of the present invention does not need to obtain a plurality of joint portions distributed in a ring shape by splicing, and has a relatively simple assembly method, and the bearing seat of the present invention increases the configuration range of the mounting portion by a wing structure, so as to increase The joint portion of the flexible circuit board and the number and arrangement range of the electronic components on the joint portion further improve the operation efficiency of the controller of the present invention.

Although the present invention has been disclosed as above with the examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some modifications and retouching without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application.
