Embodiment Construction

[0060] The following describes specific embodiments of the switching mechanism for a dual power supply switch according to the present invention with reference to the accompanying drawings. In the various drawings, the same or corresponding elements use corresponding reference numerals (for example, elements marked with "1XX" and "2XX" have the same structure and similar function). For the sake of clarity, the drawings only show the main components of the switching mechanism, and do not show other components that can easily be imagined by those skilled in the art. In the description herein, the terms "left", "right", "upper", "lower", etc. are used to describe the relative orientation of parts, and the terms "first", "second", "one", "another", etc. These terms, and other similar terms, are used to distinguish similar elements and are not intended to limit the scope of the invention.

Abstract

The invention provides a switching mechanism for a dual power supply switch, which includes a switching assembly, and the switching assembly includes a driving disc, a driving rod, an actuator and an auxiliary mechanism. The driving disc has an arc-shaped driving groove, and the driving rod extends into the driving groove; and the auxiliary mechanism has a spring. The drive plate can receive external force and rotate. When the end of the drive groove does not touch the drive rod, the drive groove bypasses the drive rod. When the end of the drive groove touches the drive rod, the drive groove pushes the drive rod to rotate through the first angle, and prompting the spring to deform; and, when the spring passes through the dead point, the spring deforms back and drives the driving rod to rotate a second angle, thereby actuating the actuator to switch on or off the first power supply. The switching mechanism may also include another switching component for switching the second power source. In addition, the present invention also provides a dual power conversion switch including such a switching mechanism.

Description

technical field [0001] The invention relates to a switching mechanism of a dual power supply switch and a dual power supply switch comprising the switching mechanism. Background technique [0002] Dual power transfer switches are widely used in emergency power supply systems, which can automatically or manually switch the load circuit from one power source to another based on the condition of the power circuit, such as switching between mains power and backup power, so as to maintain the continuity of the load circuit operate reliably. A type of dual power transfer switch has three working positions, that is, the first power position where the first power is turned on, the second power position where the second power is turned on, and the position where the first power and the second power are simultaneously disconnected. Double point position. The double-point position can meet the user's needs for delayed switching, safety inspection and other aspects. [0003] The swit...
