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 double-power-supply changeover switch. The switching mechanism comprises a switching assembly; and the switching assembly comprises a driving disc, adriving rod, an executing mechanism and an auxiliary mechanism. The driving disc is provided with an arc-shaped driving groove, and the driving rod extends into the driving groove; and the auxiliarymechanism is provided with a spring. The driving disc can receive external force to rotate; when the end part of the driving groove does not contact the driving rod, the driving groove bypasses the driving rod; when the end part of the driving groove makes contact with the driving rod, the driving groove pushes the driving rod to rotate for a first angle and causes the spring to deform; and afterthe spring is across a dead point position, the spring returns to deform and drives the driving rod to rotate for a second angle, so that the executing mechanism is actuated to turn on or off a firstpower supply. The switching mechanism also can comprise another switching assembly for switching a second power supply. In addition, the invention provides the double-power-supply changeover switch comprising the 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...
