As shown in fig. 1, some embodiments of the present invention provide a reset structure, which is mainly applied to a circuit breaker, and includes a housing 100, a driving member 200, a connecting rod 300, a rotating plate 400, and a trigger switch 500.
The trigger switch 500 may be any one of a micro switch, a touch switch, or a travel switch.
The rotating plate 400 is rotatably connected to the housing 100, and the driving member 200 is rotatably connected to the rotating plate 400 through the connecting rod 300, it can be understood that the driving member 200 drives the rotating plate 400 to rotate on the housing through the connecting rod 300 during the moving process.
Meanwhile, the driving member 200 is connected to the rotating plate 400 by an elastic member 700.
In this embodiment, the driving member 200 is caused to switch between the first position and the second position by an external force.
In addition, the driving member 200 has a critical point position in the process of switching between the first position and the second position, and the elastic member 700 is in the limit deformation state at this position, that is, the elastic member 700 in the limit deformation state has an elastic force to both the driving member 200 and the rotating plate 400.
It should be noted that, when the elastic element 700 is in the extreme deformation state, the extreme deformation state here means that, during the process of switching the driving element 200 between the first position and the second position, the deformation amount of the elastic element 700 is the largest when the elastic element 700 is at the critical point position, and when the driving element 200 passes the critical point position, the elastic element 700 generates the driving force to drive the driving element 200 to move, that is, the driving element 200 moves under the elastic force of the elastic element 700. The driving member 200 may cross the critical point during the movement of the driving member 200 along the first direction, and the critical point is crossed, and it should be noted that the first direction is the movement of the driving member 200 from the first position to the second position (i.e., the first position → the critical point position → the second position).
The driving member 200 may pass through the critical point during the movement of the driving member 200 along the second direction, and the second direction is the movement of the driving member 200 from the second position to the first position (i.e., the second position → the critical point position → the first position).
When the driving member 200 crosses the critical point position, the elastic member 700 generates a driving force to the driving member 200, so that the driving member 200 moves under the elastic force of the elastic member 700.
In addition, the trigger switch 500 is disposed inside the housing 100, and a trigger 240 is disposed on a side of the driving member 200 facing the trigger switch 500.
When the driving member 200 is in the second position, the triggering member 240 triggers the triggering switch 500, and at this time, the elastic member 700 further has a driving force on the driving member 200. Specifically, when the driving member 200 is at the first position, the driving member 200 is pushed by an external force, so that the driving member 200 moves toward the rotating plate 400, and the rotating plate 400 is pushed by the driving member 200 to rotate, after the critical point is crossed, the driving member 200 reaches the second position under the action of the external force and the driving force of the elastic member, and the trigger switch 500 is triggered by the trigger member 240, at this time, the elastic member 700 does not completely recover from deformation (still has a certain amount of deformation), so that a driving force is provided to the driving member 200, and the trigger member 240 and the trigger switch 500 are stably triggered.
When the driving member 200 is disengaged from the second position, the triggering member 240 is disengaged from the trigger switch 500, and the trigger switch 500 is not triggered. It will be appreciated that when the actuating member 200 has not reached the second position, the trigger member 240 is not in contact with the trigger switch 500 and the trigger switch 500 is not triggered.
It should be noted that the elastic member 700 may be any one of a spring or a torsion spring, and may be specifically set according to actual situations.
As shown in fig. 2, the driving member 200 is provided with a waist hole 210, and in this embodiment, the waist hole 210 is a strip-shaped hole.
One end of the connecting rod 300 penetrates through the waist hole 210, and the other end of the connecting rod 300 is rotatably connected with the rotating plate 400, so that one end of the connecting rod penetrating through the waist hole 210 has a free distance in the waist hole 210.
When the driving member 200 just departs from the second position, since the end of the connecting rod 300 penetrating through the waist hole 210 slides in the waist hole 210, the movement of the driving member 200 does not drive the connecting rod 300 to move, i.e. the connecting rod 300 keeps a static state in the process.
After the driving member 200 is completely separated from the second position, the end of the connecting rod 300 penetrating through the waist hole 210 is abutted against the wall of the waist hole 210, and the driving member 200 drives the connecting rod 300 to move, so that the rotating plate 400 rotates.
Specifically, when the driving member 200 is pulled, one end of the driving member 200 near the waist hole 210 moves in the waist hole 210, and the driving member 200 does not move the link 300 during the movement. When the driving member 200 moves a distance greater than the aperture of the waist hole 210 (the relative sliding distance between the connecting rod 300 and the waist hole 210), the driving member 200 pulls the connecting rod 300, and the trigger 240 is already disengaged from the trigger switch 500 before the driving member 200 pulls the connecting rod 300 to move, so that the action of the trigger switch 500 (the action of disengaging the trigger 240 from the trigger switch 500) can be implemented before the action of the mechanical switch controlled by the driving member.
In some embodiments of the present invention, the inner wall of the casing 100 is provided with a supporting column 600, and it should be noted that the supporting column 600 is perpendicular to the casing 100.
Meanwhile, one end of the support column 600, which is far away from the housing 100, is inserted into the rotating plate, so that the rotating plate rotates along the axis of the support column 600. It will be appreciated that the rotating plate is rotatably coupled to the support column 600.
In addition, the driving member 200 is slidably coupled to the housing 100. Specifically, when the driving member 200 moves away from the housing 100 during the sliding process, the driving member 200 moves away from the rotating plate. When the driving member 200 approaches the housing 100 during sliding, the driving member 200 moves in a direction of approaching the rotation plate 400.
In this embodiment, one end of the driving member 200 close to the rotating plate and one end of the rotating plate far from the supporting column 600 are connected by an elastic member 700.
The driving member 200 is connected to the rotating plate 400 through the connecting rod 300, so that when the driving member 200 drives the connecting rod 300 to move, the connecting rod 300 drives the rotating plate 400 to rotate around the axis of the supporting column.
It can be understood that the driving member 200 is movably connected to the rotating plate 400 by the connecting rod 310, and when the driving member 200 moves toward the rotating plate 400 or moves away from the rotating plate 400 by an external force and the connecting rod 300 moves by the driving member 200, the rotating plate 400 is driven to rotate about the axis of the supporting post 600 while moving by the connecting rod 300.
In this embodiment, the trigger switch 500 is disposed inside the housing 100, specifically, the trigger switch 500 is installed below the driving element 200, and a trigger 240 is disposed on a side of the driving element 200 facing the trigger switch 500, so that the trigger switch 500 is turned on or off by the trigger 240 in a process of sliding the driving element 200 on the housing 100.
In some embodiments of the present invention, the trigger switch 500 may be any one of a hall switch, a micro switch and a photoelectric switch, and may be specifically set according to actual conditions.
Specifically, when the trigger switch 500 is a hall switch, the trigger 240 is a magnet, and the hall switch is triggered by the magnet.
When the trigger switch 500 is a microswitch, at this time, the trigger 240 is a limit block, and the microswitch is triggered by the limit block.
When the trigger switch 500 is a photoelectric switch, the trigger 240 is a baffle, and the photoelectric switch is triggered by the baffle.
As shown in fig. 1, 2 and 5, in some embodiments of the present invention, the connecting rod 300 includes a connecting rod 310, a first limiting rod 320 and a second limiting rod 330, and the first limiting rod 320 and the second limiting rod 330 are respectively installed at two ends of the connecting rod 310.
Specifically, the first limiting rod 320 and the second limiting rod 330 are parallel to each other and located on the same side of the connecting rod 310, and the first limiting rod 320 and the second limiting rod 330 are perpendicular to the connecting rod 310 respectively.
Specifically, one end of the first limiting rod 320 is connected to one end of the connecting rod 310, and the other end of the first limiting rod 320 penetrates through the waist hole 210 and faces the inner wall of the housing 100. Meanwhile, one end of the second limiting rod 330 is connected to the other end of the connecting rod 310, and the other end of the second limiting rod 330 penetrates through one end of the rotating plate 400 far away from the supporting column 600 and faces the housing 100. It should be noted that the second limiting rod 330 is rotatably connected to the rotating plate 400.
It should be noted that, in the present embodiment, the connecting rod 310 is a bending rod, wherein the bending angle of the bending rod is an obtuse angle. So that the driving member 200 drives the connecting rod 310 to move toward or away from the rotating plate 400 during the movement of the driving member 200 on the housing 100, and the rotating plate 400 is pushed by the connecting rod 310 to rotate on the axis of the supporting post.
As shown in fig. 1, 3 and 4, in some embodiments of the present invention, a connection column 220 is disposed on a side of the driving member 200 close to the waist hole 210, and the connection column 220 is connected to one end of the rotation plate close to the second limiting rod 330 through an elastic member 700.
It should be noted that the connection column 220 is an L-shaped column, and the connection column 220 is connected with the driving member 200 to form a through hole, so that one end of the elastic member 700 passes through the through hole to be connected with the connection column 220, and meanwhile, the connection column 220 and the driving member 200 limit the elastic member 700, thereby preventing the elastic member 700 from sliding down from the connection column 220, and improving the stability of connection between the elastic member 700 and the connection column 220.
Meanwhile, the other end of the elastic member 700 is connected to one end of the rotating plate close to the second limiting rod 330.
As shown in fig. 3, in some embodiments of the present invention, a limiting platform 800 is disposed on one side of the housing 100, and the limiting platform 800 is disposed around the supporting column 600 to form a limit with the driving member 200 through the limiting platform 800.
Specifically, when the driving member 200 moves toward the rotating plate 400 by an external force, the driving member 200 abuts against the limiting table 800 at the final position. The driving member 200 is limited by the limiting table 800, so that the situation that the driving member 200 cannot reset due to the fact that the driving member 200 slides towards the rotating plate 400 under the action of external force is avoided, and the stability of the driving member 200 in the sliding process on the shell 100 is improved.
As shown in fig. 1 and 2, in some embodiments of the present invention, the inner wall of the casing 100 is provided with a limiting plate 900, and the limiting plate 900 contacts with one side of the driving member 200 close to the trigger 240 to form a limit with the trigger 240 through the limiting plate 900.
Specifically, the limiting plate 900 is perpendicular to the inner wall of the casing 100, and one sides of the limiting plate 900 and the driving element 200 close to the trigger element 240 are parallel to each other, so that the driving element 200 is limited to the trigger element 240 through the limiting plate 900 in the sliding process, and when the driving element 200 is pulled by an external force, the driving element 200 is prevented from being pulled out of the casing 100, and the stability of the driving element 200 in the casing 100 is improved.
As shown in fig. 2 and 4, in some embodiments of the present invention, the other end of the driving member 200 is provided with a pull handle 230, so that a user can pull the driving member 200 through the pull handle 230 or push the driving member 200 through the pull handle 230, thereby improving convenience for the user to move the driving member 200.
It should be noted that some embodiments of the present invention provide a reset structure at least including the following motion states, state one: the driver 200 is in the first position.
And a second state: when the driving member 200 moves in the first direction by applying an external force, the driving member 200 drives the rotating plate 400 to rotate through the connecting rod 300, and the elastic member 700 is gradually deformed, and when the driving member 200 reaches a critical point, the elastic member 700 is deformed to a maximum value, and the driving member 200 is still between the first position and the second position.
And a third state: based on the second state, at this time, when the driving member 200 continues to move towards the first direction under the action of the external force, the driving member 200 finally reaches the second position due to the crossing of the critical point under the action of the driving force of the elastic member 700 and the external force, and at this time, the trigger member 240 triggers the trigger switch 500; since the elastic member 700 is not yet completely deformed, a driving force is applied to the driving member 200 to stably actuate the actuating member 240 and the trigger switch 500.
And a fourth state: based on the third state, when the driving member 200 is pulled to move toward the second direction, because the end of the connecting rod 300 penetrating through the waist hole 210 slides in the waist hole 210, the driving member 200 moves without driving the connecting rod 300 to move, when the driving member 200 completely separates from the second position (at this time, the trigger switch 500 is also completely separated from the trigger switch 240, and therefore the trigger switch is not triggered), at this time, the end of the connecting rod 300 penetrating through the waist hole 210 is opposite to the wall of the waist hole 210, at this time, the driving member 200 drives the connecting rod 300 to move, so that the rotating plate 400 rotates, and at the same time, the elastic member 700 begins to deform until the driving member 200 reaches the critical point position.
And a fifth state: based on the fourth state, when the driving member 200 continues to move toward the second direction under the external force, the driving member 200 finally reaches the second position, i.e. returns to the first state, due to the driving force of the elastic member 700 and the external force, which exceed the threshold point.
In state four, the trigger 240 can be disengaged from the trigger switch 500, such that the circuit controlled by the trigger switch 500 is opened before the mechanical switch controlled by the driving member 200.
As shown in fig. 2 and 6, in some embodiments of the present invention, the distance from the axis of the connecting column 220 to the axis of the connecting buckle 410 is greater than the original length of the elastic member 700.
As shown in fig. 7, some embodiments of the present invention also provide a circuit breaker 1000, the circuit breaker 1000 comprising a solid state circuit switch 1100 and a mechanical switch 1200 in series relationship in a circuit relationship.
In addition, the circuit breaker 1000 further includes a reset structure described in any of the above embodiments.
As shown in fig. 8, when the trigger switch 500 is triggered, the solid-state circuit switch 1100 is turned on (the MCU receives the trigger signal to turn on the solid-state circuit switch 1100); when the trigger switch 500 is not triggered, the solid state circuit switch 1100 is turned off (the MCU does not receive a trigger signal to turn off the solid state circuit switch 1100). Such a circuit in which the MCU receives the trigger signal to turn on the solid-state circuit switch 1100, and a circuit in which the MCU does not receive the trigger signal to turn off the solid-state circuit switch 1100 belong to the common knowledge, and are not described herein again.
In all examples shown and described herein, any particular value should be construed as merely exemplary, and not as a limitation, and thus other examples of example embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The above-described embodiments are merely illustrative of several embodiments of the present invention, which are described in detail and specific, but not intended to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
