[0025] The present application will be described in further detail below through specific embodiments and in conjunction with the drawings.

[0026] The specific structure is as shown in Figures 1 to 9 .

[0027] The embodiment provides a switch toggle type locking and unlocking structure, which comprises a shell 1, a pre-charging circuit and a main switch arranged in the shell 1 in parallel, and a sliding piece 2 slidingly connected to the inner wall of the shell 1; a pre-charging switch 3 is arranged on the pre-charging circuit, a handle opening 4 is arranged on the shell 1, and a handle 5 of the main switch extends out of the shell 1 through the handle opening 4; a stop portion 6 and a first trigger portion 7 are arranged on the sliding piece 2, and the sliding piece 2 has a first position and a second position through sliding; when the sliding piece 2 is located at the first position, the stop portion 6 is located on the opening and closing movement path of the handle 5 to limit the closing of the handle 5, and the first trigger portion 7 is located at a position not triggering the pre-charging switch 3 to close; when the sliding piece 2 is located at the second position, the stop portion 6 is located outside the opening and closing movement path of the handle 5 to enable the handle 5 to close, and the first trigger portion 7 is located at a position triggering the pre-charging switch 3 to close.

[0028] In the embodiment, the pre-charging circuit is arranged in the shell 1, the pre-charging circuit is connected to the main switch in parallel, when the sliding piece 2 is located at the first position, the first trigger portion 7 is located at a position not triggering the pre-charging switch 3 to close, that is, the pre-charging switch 3 is in an open state, and the stop portion 6 is located on the opening and closing movement path of the handle 5 to limit the handle 5, thereby limiting the closing of the main switch and avoiding the damage of the main switch caused by a large impact current, when the main switch needs to be closed, the sliding piece 2 is first toggled to slide from the first position to the second position, and the operation is convenient, and when the sliding piece 2 is located at the second position, the stop portion 6 is located outside the opening and closing movement path of the handle 5 to release the limitation of the handle 5, so that the main switch can be closed, and at the same time that the stop portion 6 releases the limitation of the handle 5, the first trigger portion 7 is located at a position triggering the pre-charging switch 3 to close, that is, the pre-charging switch 3 is in a closed state, the capacitor is pre-charged, the voltage difference between the input end and the output end of the switch is small, and then the main switch is closed, since there is no large impact current, the use safety of the power supply system is effectively improved, and the opening and closing operations of the pre-charging circuit do not exceed the size of the shell 1.

[0029] In the embodiment, during the process that the sliding piece 2 is toggled to slide from the first position to the second position, the stop portion 6 can gradually exit the opening and closing movement path of the handle 5 until the limitation of the handle 5 is released, and at the same time, the first trigger portion 7 gradually presses the pre-charging switch 3 until the pre-charging switch 3 is closed, and the process that the sliding piece 2 moves from the second position to the first position is opposite to the foregoing, which will not be described herein again. The stop portion 6 of the sliding piece 2 is used for closing and unlocking the handle 5, and the first trigger portion 7 of the sliding piece 2 is used for closing and opening the pre-charging switch 3, so that the structure is simple, the use is convenient, and the user can reduce wiring.

[0030] In the optional technical scheme of the embodiment, the unlocking member 8 is movably connected to the inner wall of the shell 1, and the unlocking member 8 has a unlocking position and a locking position through movement. The unlocking member 8 is provided with a first limiting part and a second triggering part 10. The sliding member 2 is provided with a second limiting part matched with the first limiting part. The second triggering part 10 is located on the opening and closing movement path of the handle 5, and the handle 5 can switch the unlocking member 8 between the unlocking position and the locking position through the second triggering part 10 when the handle 5 is moving. When the sliding member 2 is located at the first position, the unlocking member 8 is located at the unlocking position, the first limiting part is separated from the second limiting part, and the unlocking state is achieved, so that the sliding member 2 can slide in the direction from the first position to the second position. When the sliding member 2 is located at the second position, the unlocking member 8 is located at the locking position, the first limiting part is in contact with the second limiting part, and the locking state is achieved, so as to limit the sliding of the sliding member 2 in the direction from the second position to the first position.

[0031] In the embodiment, the stop part 6 is located near the open position of the handle 5, and can limit the handle 5 at the open position. The second triggering part 10 is located near the closed position of the handle 5, and the handle 5 can switch the unlocking member 8 from the locking position to the unlocking position through the second triggering part 10 when the handle 5 is closing. Specifically, when the sliding member 2 slides from the first position to the second position, the unlocking member 8 is switched from the unlocking position to the locking position, the first limiting part is switched from the separated unlocking state to the contacting locking state, the sliding member 2 is locked by the unlocking member 8, the sliding member 2 is kept at the second position, the pre-charging switch 3 is kept in the closed state, the pre-charging circuit is kept in the charging state, the main switch can be closed, and the handle 5 passes through the second triggering part 10 before moving from the open position to the closed position during the closing process. The handle 5 drives the second triggering part 10 to move away from the sliding member 2, switches the unlocking member 8 from the locking position to the unlocking position, and slides the sliding member 2 from the second position to the first position to make the pre-charging switch 3 in the open state. When the handle 5 is located at the closed position, the unlocking member 8 is kept at the unlocking position through the second triggering part 10. Since the handle 5 has unlocked the sliding member 2 after being located at the closed position, the pre-charging switch 3 is kept in the closed state before the handle 5 is located at the closed position, and the stop part 6 of the sliding member 2 avoids interfering with the handle 5 during the closing movement.

[0032] In the embodiment, the first limiting part can be a limiting groove 11, and the second limiting part can be a limiting protrusion 9. Alternatively, the first limiting part can be a limiting protrusion 9, and the second limiting part can be a limiting groove 11.

[0033] In the optional technical scheme of the embodiment, the stop portion 6 is provided with a stop straight surface 12 for limiting the closing of the handle 5 on the side of the handle 5 towards the open position, and is provided with an inclined surface 13 for enabling the opening of the handle 5 on the side of the handle 5 towards the closed position; the sliding piece 2 further has a third position by sliding, and the third position is between the first position and the second position; the handle 5 can drive the sliding piece 2 to slide from the first position to the third position through the inclined surface 13 when the handle 5 is in the open movement; when the sliding piece 2 is in the third position, the first trigger portion 7 is in the position of not triggering the closing of the pre-charging switch 3, the unlocking piece 8 is in the unlocking position, and the first limiting portion and the second limiting portion are in the unlocking state, so that the sliding piece 2 can slide in the direction from the second position to the first position.

[0034] In the embodiment, the handle 5 is limited by the stop straight surface 12 when the handle 5 is in the open position, so that the handle 5 is prevented from moving in the direction of the closed position, and the limiting effect is good. When the handle 5 is in the open process, the handle 5 passes through the stop portion 6 and contacts the inclined surface 13 of the stop portion 6 before moving from the closed position to the open position. When the handle 5 continues to open after contacting the inclined surface 13, the handle 5 will push the sliding piece 2 to slide and exit the opening and closing movement path of the handle 5 through the inclined surface 13, so as to avoid affecting the opening of the handle 5. Meanwhile, the farthest position of the sliding piece 2 pushed to slide by the handle 5 contacting the inclined surface 13 is the third position, and when the sliding piece 2 is in the third position, the first trigger portion 7 will not switch the pre-charging switch 3 from the open state to the closed state, the unlocking piece 8 is in the unlocking position, and the first limiting portion and the second limiting portion are in the unlocking state. At this time, the sliding piece 2 can slide in the direction from the second position to the first position. When the handle 5 moves to the open position, the sliding piece 2 can be slid in the direction from the second position to the first position, so that the sliding piece 2 is in the first position, and the stop portion 6 continues to limit the handle 5.
