AI Technical Summary
Technical Problem
The existing brushless motor controller requires the four corner snap-fit components to be operated eight times when disassembling and installing the cover, resulting in a slow maintenance speed.
Method used
The control mechanism employs gears, racks, and clamps. The rotating gears drive the rack to move the clamps, enabling quick assembly and disassembly of the outer shell and cover. The clamps can be assembled and disassembled in just two operations.
Benefits of technology
It improves the maintenance speed of brushless motor controllers, simplifies the disassembly and assembly process, and enhances the stability and fixing effect of the card plate.

Abstract
This utility model discloses a brushless motor controller that is easy to maintain. It includes a housing, an inner cover, and a controller chip fixedly connected to the bottom of the inner wall of the housing. Slots are formed on the top of both sides of the inner wall of the housing, and locking plates are installed inside the slots. A limit cover is fixedly connected to the top of the cover, with the locking plates located on both sides inside the limit cover. A control mechanism is installed inside the limit cover. This utility model utilizes a rotating gear, which drives a rack to move inward, which in turn drives the locking plates to move inward. The locking plates compress a spring, disengaging from the slots. With the slots and locking plates no longer fixed, the housing and cover are also no longer fixed. Moving the cover upward allows it to exit from the housing, enabling the controller chip to be inspected. This design offers the advantage of quick maintenance. The locking assembly only requires two operations to detach and reassemble the housing and cover, significantly improving the maintenance speed of the brushless motor controller.
