[0002] The inverter circuit board is one of the core components of an inverter. It is responsible for controlling the operation of the inverter and interacting with the motor. An inverter is essentially a device used to regulate the speed of an AC motor by changing the power supply frequency of the motor. Therefore, its circuit board design is crucial. The inverter circuit board is one of the core components of an inverter, responsible for controlling and managing the operating status of the motor. Its design and maintenance directly affect the performance and lifespan of the equipment. Understanding the working principle, common faults, and maintenance points of the inverter circuit board can help users better use and maintain the inverter, and improve the stability and efficiency of the equipment.
[0003] Inverter circuit boards need to be periodically removed from their brackets for maintenance and dust removal. However, typical inverter circuit boards are difficult to remove quickly from the brackets, requiring considerable time and significantly reducing work efficiency. Furthermore, the installation of inverter circuit boards is complex, and the tools used during installation can easily damage the boards, making them unusable. When replacing or upgrading circuit boards, their dimensions may change, and typical mounting brackets are insufficient to effectively secure them, leading to uneven stress, damage from excessive force, or loosening due to insufficient force. To address these issues, a quick-release inverter circuit board bracket is proposed as a solution. Utility Model Content

The upper end of the first spring 606 is fixedly connected to the lower side of the connecting plate 604, and the lower end of the first spring 606 is fixedly connected to the upper side of the mounting plate 1. A sliding plate 607 is slidably connected inside the fixed square tube 601. Several second positioning holes 608 are opened through the upper side of the sliding plate 607 near the mounting support 3.
[0019] Specifically, a support plate 609 is fixedly connected to the upper side of the slide plate 607 away from the mounting bracket 3. A second rubber pad 610 is fixedly connected to the upper side of the support plate 609 to effectively protect the circuit board.

The slot 614 engages with the four sides of the circuit board to fix the circuit board and complete the installation of the circuit board. When disassembling, simply pull the clamping plate 612 outward to remove the circuit board.
