DETAILED DESCRIPTION
[0040] The following embodiments are further illustrated by the accompanying drawings to further illustrate the specific implementation of the operating mechanism of the dual power switch of the utility model. The operating mechanism of the dual power switch of the utility model is not limited to the description of the following embodiments.
[0041] As Figure 1 , 2As shown, the operating mechanism of the dual power switch includes a swing arm 3 and two main electromagnetic driving mechanisms 2, the two main electromagnetic driving mechanisms 2 are connected with two ends of the swing arm 3 through two link assemblies 6, the main electromagnetic driving mechanisms 2 are switched between the first position and the second position to drive the connected link assemblies 6 to move between the first position and the second position, the swing arm 3 is driven to rotate through the connected link assemblies 6, the rotating shaft 5 connected with the swing arm 3 drives the contacts in the switch to open and close, generally, the swing arm 3 swings between the first on position and the second on position, when the swing arm 3 rotates to the first on position or the second on position, one of the main electromagnetic driving mechanisms 2 remains in the first position, i.e. drives the corresponding link assembly 6 to move to the first position, the other main electromagnetic driving mechanism 2 remains in the second position, and the corresponding link assembly 6 also remains in the second position, it can also be understood that, the two main electromagnetic driving mechanisms 2 correspond to the normal power supply and the backup power supply respectively, when the swing arm 3 is in the first on position, the main electromagnetic driving mechanism 2 corresponding to the normal power supply remains in the first position, and the main electromagnetic driving mechanism 2 corresponding to the backup power supply remains in the second position, at this time, the normal power supply is disconnected and the backup power supply is turned on, when the swing arm 3 is in the second on position, the main electromagnetic driving mechanism 2 corresponding to the backup power supply remains in the first position, and the main electromagnetic driving mechanism 2 corresponding to the normal power supply remains in the second position, at this time, the backup power supply is disconnected and the normal power supply is turned on.
[0042] As shown in the figure, Figures 2-9 The improvement of the present application lies in further comprising an interlocking mechanism 4, the interlocking mechanism 4 includes a tripping piece 41 rotatably assembled, the tripping piece 41 is connected with two locking assemblies 44, each locking assembly 44 is rotatably assembled and cooperates with one end of the swing arm 3, when the swing arm 3 is in the first on position or the second on position, the tripping piece 41 is in the original position, one of the locking assemblies 44 is locked with one end of the swing arm 3, and the other locking assembly 44 is separated from the other end of the swing arm 3, before the swing arm 3 is driven to rotate to switch positions, the tripping piece 41 is driven to rotate to the unlocking position, and the two locking assemblies 44 are respectively driven to rotate by the tripping piece 41, so that the two locking assemblies 44 are respectively separated from the two ends of the swing arm 3.
[0043] In this way, by driving the tripping piece 41 in the interlocking mechanism 4, the unlocking and locking of the swing arm 3 in different positions are realized, which has the advantages of simple structure, convenient operation and small space occupation.
[0044] Further, the interlocking mechanism 4 further comprises a tripping electromagnetic driving mechanism, which drives the tripping member 41 to rotate between the original position and the unlocking position. The tripping electromagnetic driving mechanism drives the tripping member 41 to rotate, so that the interlocking mechanism 4 is unlocked, which has the advantages of quick and convenient operation. Of course, the interlocking mechanism 4 can also comprise a tripping button, which is linked with the tripping member 41. The tripping button is manually operated to drive the tripping member 41 to rotate between the original position and the unlocking position.
[0045] Specifically, each locking assembly 44 comprises a jump buckle 441, a linkage connecting rod 442 and a locking reset member 443. The jump buckle 441 and the linkage connecting rod 442 are respectively rotationally assembled. The jump buckle 441 and one end of the linkage connecting rod 442 are slidingly matched, so that the jump buckle 441 and the linkage connecting rod 442 can slide relative to each other when matched. The other end of the jump buckle 441 is limitingly matched with one end of the swing arm 3 to lock the swing arm 3. The limitingly matched structure of the jump buckle 441 and the swing arm 3 can be realized by a recess and a boss matched with each other, or a limiting portion 4411 and a shaft rod, etc. The other end of the linkage connecting rod 442 is linked with the tripping member 41. The locking reset member 443 is connected to the jump buckle 441 to provide a reset force for the locking assembly 44.
[0046] Preferably, the two ends of the swing arm 3 are respectively assembled with limiting shafts 32. One end of the jump buckle 441 is provided with a limiting portion 4411. The side of the limiting portion 4411 facing the limiting shaft 32 is a sliding surface 4412. When the swing arm 3 is in the first or second on position, the tripping member 41 is in the original position. One of the limiting shafts 32 is limitingly matched with the limiting portion 4411 of one of the jump buckles 441 to lock one end of the swing arm 3. The other limiting shaft 32 is matched with the sliding surface 4412 of the other jump buckle 441 (see Figures 3-5 , 7 and 8). Before the swing arm 3 is driven to rotate, the tripping member 41 is driven to rotate from the original position to the unlocking position (see Figure 6 ). The limiting shaft 32 of the swing arm 3 limitingly matched with the limiting portion 4411 is separated and unlocked. With the swing arm 3 being further driven to rotate, the two limiting shafts 32 slide along the two sliding surfaces 4412 in opposite directions, until one of the limiting shafts 32 is again limitingly matched with the limiting portion 4411 to lock the swing arm 3. At this time, it can be understood that a position switching is performed between the two on positions, i.e., from the first on position to the second on position, or from the second on position to the first on position.
[0047] The tripping member 41 can be driven to rotate to the unlocking position by the tripping electromagnetic driving mechanism or other components. For example, the tripping member 41 can be driven by other actuatable driving mechanisms. The actuatable driving mechanisms can be manually operated buttons, or other accessory modules in switches.

The end of each main electromagnetic drive mechanism 2 away from the fixed plate 102 corresponds to the swing arm 3. A connecting rod assembly 6 is connected between each main electromagnetic drive mechanism 2 and one end of the swing arm 3. The connecting rod assembly 6 includes at least one connecting rod. In this embodiment, the connecting rod assembly 6 includes one connecting rod.

In the figure, the opening electromagnetic drive mechanism is fixed on one side of the assembly cavity 10 away from the fixed plate 102, the tripping member 41 is rotatably assembled in the assembly cavity 10, that is, it is rotatably assembled on the side plate 101, and the tripping member 41 is driven by the electromagnetic drive mechanism to rotate between the original position and the unlocked position, the two locking assemblies 44 are respectively rotatably assembled in the assembly cavity 10, and the two locking assemblies 44 are rotationally symmetrically arranged on opposite sides of the swing arm 3, one end of each locking assembly 44 is linked to the tripping member 41, and the other end of each locking assembly 44 cooperates with one end of the adjacent swing arm 3.

Subsequently, the main electromagnetic drive mechanism 2 on the commonly used side is switched from the first position to the second position, and the main electromagnetic drive mechanism 2 on the standby side is switched from the second position to the first position, and one end of the swing arm 3 on the corresponding standby side slides along the sliding surface 4412 until it is limited and matched with the limit platform 4411 of the tripping buckle 441. The above process can be understood as switching from the first connection position to the second connection position.

At this time, the power supply of the standby side is connected and the power supply of the common side is disconnected.
