The slider also has a third position by sliding, and the third position is located between the first position and the second position. When the handle is opened, the slider can slide from the first position to the third position through the inclined surface. When the slider is in the third position, the first trigger part is in the position where the precharge switch is not triggered to close.

[0007] In an optional embodiment, a first return spring is further included for providing the slider with a moving force in the direction from the second position to the first position; The inner wall of the housing is provided with a first mounting groove, and the side of the sliding member opposite to the inner wall of the housing is provided with a second mounting groove.

[0011] In an optional embodiment, the inner wall of the housing is provided with a groove, and the sliding member is slidably connected to the groove; Along the sliding direction of the slider, the stop is located at the end of the slider near the handle opening, and the first trigger is located on the side of the slider away from the inner wall of the housing.

[0012] In an optional embodiment, the housing is provided with an elongated hole, and the sliding member is provided with a toggle part on the side facing the inner wall of the housing; The actuating part is located at the elongated hole.

[0013] Secondly, this utility model provides a switch, including the switch toggle locking and unlocking structure described in any of the foregoing embodiments.

[0014] Compared with the prior art, the technical advantages of the switch-toggle locking and unlocking structure and switch provided by this utility model are as follows: The present invention provides a switch-type locking and unlocking structure, comprising: a housing, a pre-charge circuit and a main switch disposed in parallel within the housing, and a sliding member slidably connected to the inner wall of the housing; a pre-charge switch is provided on the pre-charge circuit, and a handle opening is provided on the housing, through which the handle of the main switch extends out of the housing; a stop part and a first trigger part are provided on the sliding member, and along the sliding direction of the sliding member, the sliding member has a first position and a second position; when the sliding member is in the first position, the stop part is located on the opening and closing movement path of the handle to limit the closing of the handle, and the first trigger part is located in the position where the pre-charge switch is not triggered to close; when the sliding member is in the second position, the stop part is located outside the opening and closing movement path of the handle to enable the handle to close, and the first trigger part is located in the position where the pre-charge switch is triggered to close.

[0015] A pre-charge circuit is added inside the housing, connected in parallel with the main switch. When the slider is in the first position, the first trigger is in the position where the pre-charge switch is not triggered to close, i.e., the pre-charge switch is in the open state. The stop is located on the opening and closing movement path of the handle, limiting the main switch from closing and preventing damage to the main switch from a large inrush current. When the main switch needs to be closed, the slider is first moved from the first position to the second position, which is convenient to operate. When the slider is in the second position, the stop is located outside the opening and closing movement path of the handle, thus releasing the limit on the handle and allowing the main switch to close. At the same time as the stop releases the limit on the handle, the first trigger is located in the position that triggers the pre-charge switch to close, i.e., the pre-charge switch is in the closed state, pre-charging the capacitor and reducing the voltage difference between the input and output terminals of the switch. Then the main switch is closed. Since there is no large inrush current, the safety of the power supply system is effectively improved. At the same time, the opening and closing operations of the pre-charge circuit do not exceed the size of the housing itself.

[0016] The switch provided by this utility model includes the above-mentioned switch toggle locking and unlocking structure. Therefore, the technical advantages and effects achieved by it include the technical advantages and effects achieved by the above-mentioned switch toggle locking and unlocking structure, which will not be described in detail here.

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

[0026] The specific structure is as follows: Figures 1 to 9 As shown.

[0027] This embodiment provides a switch-type locking and unlocking structure, including: a housing 1, a pre-charge circuit and a main switch disposed in parallel within the housing 1, and a sliding member 2 slidably connected to the inner wall of the housing 1; a pre-charge switch 3 is provided on the pre-charge circuit, a handle opening 4 is provided on the housing 1, and the handle 5 of the main switch extends out of the housing 1 through the handle opening 4; the sliding member 2 is provided with a stop part 6 and a first trigger part 7, and along the sliding direction of the sliding member 2, the sliding member 2 has a first position and a second position by sliding; when the sliding member 2 is in the first position, the stop part 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 part 7 is located in the position where the pre-charge switch 3 is not triggered to close; when the sliding member 2 is in the second position, the stop part 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 part 7 is located in the position where the pre-charge switch 3 is triggered to close.

[0028] In this embodiment, a pre-charge circuit is added inside the housing 1. The pre-charge circuit is connected in parallel with the main switch. When the sliding member 2 is in the first position, the first triggering part 7 is in the position where the pre-charge switch 3 has not been triggered to close, that is, the pre-charge switch 3 is in the open state. The stop part 6 is located on the opening and closing movement path of the handle 5 to limit the handle 5, restricting the main switch from closing and avoiding damage to the main switch by a large inrush current. When the main switch needs to close, the sliding member 2 is first moved to slide from the first position to the second position, which is convenient to operate. When the sliding member 2 is in the second position... When in position, the stop part 6 is outside the opening and closing movement path of the handle 5, thereby releasing the limit on the handle 5 and allowing the main switch to close. At the same time that the stop part 6 releases the limit on the handle 5, the first trigger part 7 is located at the position that triggers the precharge switch 3 to close, that is, the precharge switch 3 is in the closed state, precharges the capacitor, reduces the voltage difference between the input and output terminals of the switch, and then closes the main switch. Since there is no large inrush current, the safety of the power supply system is effectively improved. At the same time, the opening and closing operations of the precharge circuit do not exceed the size of the housing 1 itself.

[0029] In this embodiment, as the slider 2 is moved from the first position to the second position, the stop 6 gradually exits the opening and closing movement path of the handle 5 until the limitation on the closing of the handle 5 is released. At the same time, the first trigger 7 gradually presses the precharge switch 3 until the precharge switch 3 is closed. The process of the slider 2 moving from the second position to the first position is the reverse of the above, and will not be described again here. The closing and unlocking of the handle 5 by the stop 6 of the slider 2 and the closing and opening of the precharge switch 3 by the first trigger 7 of the slider 2 have a simple structure, are easy to use, and can reduce user wiring.

[0030] In the optional technical solution of this embodiment, an unlocking member 8 is movably connected to the inner wall of the housing 1. The unlocking member 8 has an unlocked position and a locked 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 that cooperates with the first limiting part. The second triggering part 10 is located on the opening and closing movement path of the handle 5. When the handle 5 opens and closes, the second triggering part 10 can switch the unlocking member 8 between the unlocked position and the locked position. When the sliding member 2 is in the first position, the unlocking member 8 is in the unlocked position, and the first limiting part and the second limiting part are separated and in the unlocked state, so that the sliding member 2 can slide along the direction from the first position to the second position. When the sliding member 2 is in the second position, the unlocking member 8 is in the locked position, and the first limiting part and the second limiting part are connected and in the locked state, so as to restrict the sliding member 2 from sliding along the direction from the second position to the first position.

[0031] In this embodiment, the stop part 6 is located near the open position of the handle 5, which can limit the handle 5 to the open position. The second trigger part 10 is located near the closed position of the handle 5, and when the handle 5 is closed, the second trigger part 10 can switch the unlocking member 8 from the locked position to the unlocked position. Specifically, when the slider 2 slides from the first position to the second position, the unlocking member 8 switches from the unlocked position to the locked position. The first limit part and the second limit part change from the separated unlocked state to the connected locked state. The slider 2 is locked by the unlocking member 8, keeping the slider 2 in the second position and keeping the precharge switch 3 in the closed state, ensuring that the precharge circuit is in the charging state. At this time, the main switch can be closed. During the closing process, the handle 5 moves from the open position to the closed position and passes through the second trigger part 10. The handle 5 drives the second trigger part 10 to move away from the slider 2, switching the unlocking member 8 from the locked position to the unlocked position. At this time, the slider 2 can be slid from the second position to the first position, keeping the precharge switch 3 in the open state. When the handle 5 is in the closed position, the unlocking member 8 is always kept in the unlocked position through the second trigger part 10. Since the handle 5 is already in the closed position, the slider 2 is unlocked, ensuring that the precharge switch 3 is in the closed state before the handle 5 is in the closed position, while avoiding interference from the stop part 6 of the slider 2 to the handle 5 during the closing movement.

[0032] In this embodiment, the first limiting part can be a limiting groove 11 and the second limiting part can be a limiting protrusion 9; or 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 solution of this embodiment, the stop part 6 is provided with a stop surface 12 for limiting the closing of the handle 5 on the side facing the open position of the handle 5, and an inclined surface 13 for enabling the handle 5 to open on the side facing the close position of the handle 5; the slider 2 also has a third position by sliding, and the third position is located between the first position and the second position. When the handle 5 moves to open, the slider 2 can slide from the first position to the third position through the inclined surface 13; when the slider 2 is in the third position, the first trigger part 7 is in the position where the precharge switch 3 is not triggered to close, the unlocking part 8 is in the unlocked position, and the first limit part and the second limit part are in the unlocked state, so that the slider 2 can slide along the direction from the second position to the first position.

[0034] In this embodiment, when the handle 5 is in the open position, the stop surface 12 limits the handle 5 to prevent it from moving towards the closed position, thus achieving a good limiting effect. When the handle 5 is in the process of opening the circuit breaker, before moving from the closed position to the open position, the handle 5 passes through the stop part 6 and contacts the inclined surface 13 of the stop part 6. After the handle 5 contacts the inclined surface 13, if the circuit breaker continues to open, the handle 5 will push the slider 2 to slide through the inclined surface 13 and exit the opening and closing movement path of the handle 5 to avoid affecting the opening of the handle 5. At the same time, the farthest position pushed by the contact between the handle 5 and the inclined surface 13 is the third position. When the slider 2 is in the third position, the first trigger part 7 will not switch the precharge switch 3 from the open state to the closed state. The unlocking part 8 is in the unlocked position, and the first limit part and the second limit part are in the unlocked state. At this time, the slider 2 can slide along the direction from the second position to the first position. When the handle 5 moves to the open position, the slider 2 can be slid along the direction from the second position to the first position, so that the slider 2 is in the first position, and the stop part 6 continues to limit the handle 5.

[0035] In the optional technical solution of this embodiment, a first reset spring 14 is also included for providing the sliding member 2 with a moving force in the direction from the second position to the first position; the inner wall of the housing 1 is provided with a first mounting groove 15, the side of the sliding member 2 away from the inner wall of the housing 1 is provided with a second mounting groove 16, and one end of the first reset spring 14 is provided in the first mounting groove 15 and the other end is provided in the second mounting groove 16.

[0036] In this embodiment, during the process of the handle 5 opening the circuit breaker, the sliding member 2 is driven from the first position to the third position, and the first reset spring 14 is gradually compressed. When the handle 5 moves to the open position, the first reset spring 14 drives the sliding member 2 from the third position to the first position. The structure is simple, the drive is stable, and the reset is convenient.

[0037] In the optional technical solution of this embodiment, the unlocking member 8 is L-shaped and has a first segment and a second segment. The first limiting part is located at the end of the first segment away from the second segment, and the second triggering part 10 is located at the end of the second segment away from the first segment. A slot 17 is provided on the housing 1, and the unlocking member 8 is movably disposed in the slot 17.

[0038] In this embodiment, the unlocking component 8 is L-shaped. During the closing process of the handle 5, the unlocking component 8 moves along the opening direction of the handle 5 and moves from the locked position to the unlocked position. The sliding direction of the sliding component 2 is perpendicular to the opening and closing direction of the handle 5. Along the opening and closing direction of the handle 5, the second limiting part is located at the end of the sliding component 2 facing the closing position of the handle 5. The overall structure is simple, the unlocking component 8 and the sliding component 2 are easy to cooperate and occupy little space.

[0039] In an optional technical solution of this embodiment, a second return spring 18 is further included to provide the unlocking member 8 with a moving force in the direction from the unlocked position to the locked position, and the second return spring 18 is sleeved on the first segment; the first segment is provided with an anti-disengagement part 19, and the second return spring 18 is located between the anti-disengagement part 19 and the slot 17. The anti-disengagement part 19 is used to prevent the second return spring 18 from disengaging from the first segment, wherein the anti-disengagement part 19 may be a circumferential rib, protrusion, or other structure that can prevent the second return spring 18 from disengaging from the first segment.

[0040] In this preferred embodiment, the first limiting part is a limiting protrusion 9, and the second limiting part is a limiting groove 11. When the sliding member 2 is not in the second position, the limiting protrusion 9 always abuts against the end of the sliding member 2 where the limiting groove 11 is provided, so that when the unlocking member 8 is in the unlocking position, the second return spring 18 is in a compressed state. When the sliding member 2 is in the second position, the second return spring 18 can drive the unlocking member 8 to move from the unlocking position to the locking position. The overall structure is simple, the unlocking member 8 is easy to drive, and the stability is high.

[0041] In an optional technical solution of this embodiment, a buffer slope 20 is provided between the first limiting part and the second limiting part. When the first limiting part and the second limiting part are in the locked state, the buffer slope 20 is used to enable the slider 2 to move along the direction from the first position to the second position. This prevents structural damage caused by excessive sliding when the slider 2 slides from the first position to the second position.

[0042] In this embodiment, a buffer slope 20 may be provided on the side of the limiting protrusion 9 facing the handle opening 4, or a buffer slope 20 may be provided on the inner wall of the limiting groove 11 near the handle opening 4; preferably, a buffer slope 20 may be provided on both the side of the limiting protrusion 9 facing the handle opening 4 and the inner wall of the limiting groove 11 near the handle opening 4.

[0043] In the optional technical solution of this embodiment, the inner wall of the housing 1 is provided with a groove 21, and the slider 2 is slidably connected to the groove 21. Along the sliding direction of the slider 2, the stop part 6 is located at the end of the slider 2 near the handle opening 4, and the first trigger part 7 is located on the side of the slider 2 away from the inner wall of the housing 1. The slider 2 has a simple structure and is easy to manufacture, but it is not limited to this. The stop part 6 can also be located on the side of the slider 2 away from the inner wall of the housing 1, and the first trigger part 7 can also be located at the end of the slider 2 near the handle opening 4. Preferably, the first trigger part 7 is a trigger block, which has a simple structure and a stable triggering effect.

[0044] In the optional technical solution of this embodiment, the housing 1 is provided with an elongated hole 22, and the sliding member 2 is provided with a toggle part 23 on the side facing the inner wall of the housing 1; the toggle part 23 is located at the elongated hole 22. The sliding member 2 is driven to slide by toggle the toggle part 23, which has a simple structure and facilitates the movement of the sliding member 2. Preferably, the toggle part 23 is provided with an anti-slip structure, which can be an anti-slip texture, an anti-slip pad, or other anti-slip structure that meets the requirements.

[0045] This embodiment provides a switch including the aforementioned switch toggle locking and unlocking structure.
