The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In one aspect of the embodiment of the present application, an energy storage tripping device is provided, as shown in fig. 1, including a base 100, and an energy storage assembly 120, an elastic member 130, a chuck 140, a tripping assembly and a locking assembly 150 disposed on the base 100; as shown in fig. 1, the base 100 may include a mounting base 101, an upper cover 102 and a mounting box 103, wherein the mounting base 101 and the upper cover 102 may be fastened to each other to form a housing having an inner cavity, the mounting box 103 and the housing may be separately formed, the mounting box 103 is externally connected to the housing, of course, the mounting box 103 and the housing may also be integrally formed, and when being arranged, the energy storage assembly 120, the elastic member 130, the chuck 140, the trip assembly and the latch assembly 150 are fixedly or movably disposed on the mounting base 101, the upper cover 102 and the mounting box 103 as required, for example, as shown in fig. 2, the energy storage assembly 120, the elastic member 130, the chuck 140 and the latch assembly 150 are disposed inside the housing, and the trip assembly (not shown) is correspondingly disposed on the mounting box 103. In some embodiments, as shown in fig. 3, a containing groove 1024 is disposed on one side of the upper cover 102, which is engaged with the mounting seat 101, and a positioning pillar 1023 is disposed in the containing groove 1024, the energy storage element 122 of the energy storage element 120 can be contained in the containing groove 1024, and the periphery of the positioning pillar 1023 is sleeved to achieve stability of the energy storage element 122 after assembly, a shaft hole can be further disposed on the positioning pillar 1023 in a penetrating manner, so that the rotating shaft 1211 of the engaging and disengaging element 121 of the energy storage element 120 extends out of the housing through the shaft hole to be connected with the handle 110, and the connection manner can be clamping or pin connection.

As shown in fig. 2 to 9, two ends of the elastic member 130 are respectively connected to the energy storage assembly 120 and the chuck 140 (the connection here may be an abutting connection or a fixed connection); the chuck 140 can be clamped with the base 100 at different positions when in the opening position and the closing position, for example, as shown in fig. 3 and 4, the chuck 140 is rotatably disposed in the cavity of the mounting base 101, the closing limiting part 1021 and the opening limiting part 1022 are disposed at different positions of the upper cover 102, the chuck 140 can be clamped with the closing limiting part 1021 when in the closing position, and the chuck 140 can be clamped with the opening limiting part 1022 when in the opening position; the trip assembly is drivingly connected to the latching assembly 150 (the driving connection fingers may be always in driving relation or may be established only when needed).

When the energy storage assembly 120 abuts against the locking assembly 150, the energy storage assembly 120 can maintain an energy storage state (for convenience of description, this position may be referred to as an energy storage maintaining position), at this time, the chuck 140 is also in a clamping state with the base 100 (closing limiting portion 1021), and the chuck 140 is located at a closing position. When the brake is required to be opened, the trip component drives the locking component 150 to move under the control of the trip signal, so that the locking component 150 is released from abutting against the energy storage component 120, and at the moment, the energy storage component 120 releases energy. In the process of releasing energy from the energy storage assembly 120, because the chuck 140 is still clamped with the base 100 at the closing position, the energy storage assembly 120 drives the elastic member 130 to store energy first, and after the energy is stored in the elastic member 130, the energy storage assembly 120 drives the chuck 140 along with the continued energy release of the energy storage assembly 120, so that the chuck 140 and the base 100 are released from clamping at the closing position, at this time, the elastic member 130 after storing energy starts to release energy and drives the chuck 140 to move towards the opening direction until the chuck 140 moves to the opening position, that is, the opening power of the whole mechanism comes from the energy stored when the energy storage assembly 120 maintains the energy storage position.

For convenience of description, during the energy releasing process of the energy storage assembly 120, the position where the energy storage assembly 120 drives the chuck 140 to be disengaged from the base 100 is called a brake-off dead center position. It should be understood that, in the process before the energy storage assembly 120 moves from the energy storage holding position to the opening dead point position, the force value of the energy storage assembly 120 is gradually reduced, and at the same time, the force value of the elastic member 130 is gradually increased, so that before the opening dead point position, when the force value of the energy storage assembly 120 is greater than the force value of the elastic member 130, the energy storage assembly 120 can move to the opening dead point position, thereby reliably opening the whole mechanism and improving the safety of opening the door. It should be noted that the force value of the energy storage assembly 120 is the magnitude of the elastic force of the energy storage assembly 120, and similarly, the force value of the elastic member 130 is also the magnitude of the elastic force of the elastic member 130.

As shown in fig. 12, a straight line a indicates a change of a force value F of the energy storage assembly during the movement of the energy storage assembly from the energy storage maintaining position m to the opening dead point position n; and the straight line c indicates the change of the elastic force value F in the process that the energy storage assembly moves from the energy storage keeping position m to the opening dead point position n. As can be known from the graph 12, in the energy storage assembly by keeping energy storage position m towards separating brake dead point position n motion process, the power value F of energy storage assembly reduces gradually, and the power value F of elastic component increases gradually, so, before separating brake dead point position, when making the power value of energy storage assembly be greater than the power value of elastic component, make energy storage assembly can move to separating brake dead point position, thereby make the reliable separating brake of whole mechanism, improve the security of separating brake. It should be noted that, in the opening dead point position, two situations should be included, and the force value of the energy storage assembly is greater than or equal to the force value of the elastic member.

In some embodiments, a closing process is further included, that is, in the open position, the energy storage assembly 120 does not abut against the locking assembly 150, and the chuck 140 and the base 100 (the opening limiting part 1022) are in a clamping state. When the switch needs to be switched on, an external force is applied to the energy storage assembly 120, the energy storage assembly 120 starts to store energy by itself on the one hand, and on the other hand, because the chuck 140 is still clamped with the base 100 at the switch-off position, the energy storage assembly 120 can drive the elastic element 130 to store energy, after the energy storage of the elastic element 130 is completed, the energy storage assembly 120 continues to store energy and drives the chuck 140 to release the clamping with the base 100 at the switch-off position, at this time, the elastic element 130 after storing energy starts to release energy and drives the chuck 140 to move towards the switch-on direction until the chuck 140 moves to the switch-on position (i.e. the chuck 140 is clamped with the base 100 at the switch-on position), and then the energy storage assembly 120 can also continue to store energy until the energy storage position is kept abutted against the locking assembly 150 and enters the energy storage state. Therefore, when the brake is required to be opened, the reliable opening can be carried out through the opening process, and the brake opening and closing function of the energy storage tripping device is realized. After chuck 140 moves to the on-position earlier, energy storage component 120 continues to move one section route again and just reaches and keeps the energy storage position, so, be in the on-position earlier at chuck 140, but energy storage component 120 does not move when keeping the energy storage position, removes external force, can make whole mechanism get back to the position of separating brake according to aforementioned mode by energy storage component 120's release, when can guaranteeing energy storage component 120 to accomplish the energy storage, the mechanism has reliably closed a floodgate, avoids appearing closing a floodgate not in place's the condition.

Alternatively, as shown in fig. 9, the chuck 140 is rotatably disposed in the chamber of the base 100 and is in driving connection with the contact device 200, so that when the chuck 140 rotates from the open position to the close position or from the close position to the open position, the opening and closing of the contact device 200 are realized.

When the closing is required, the external force drives the shaft 1211, the shaft 1211 drives the closing plate 1212 to rotate toward the closing direction, during the rotation of the closing plate 1212, the closing plate 1212 drives the energy storage element 122 to deform and store energy through the driving portion 1214, and the closing and opening energy storage protrusion 1215 pushes the elastic element 130 to deform and store energy (because the chuck 140 is clamped with the opening limiting portion 1022 of the base 100 at the opening position through the claw 141 at this time), meanwhile, the closing plate 1212 also rotates relative to the chuck 140, after the energy storage of the elastic element 130, the closing convex edge 1213 of the closing plate 1212 moves to the closing claw 141 of the chuck 140, slides along the guiding wall, and presses the closing claw 141 to deform while sliding, so that the closing claw 141 is released from the clamping with the opening limiting portion 1022 of the upper cover 102 (one limit in the closing rotation direction is released), and the chuck 140 rotates toward the closing position under the release energy of the elastic element 130, namely, the closing limiting part 1021 facing the upper cover 102 rotates to drive the contact device 200 to move towards the closing direction, when the chuck 140 moves to the closing limiting part 1021 of the upper cover 102 and the closing limiting part 1021 is located in the accommodating space 142 between the two jaws 141, the contact device 200 completes closing, and then the closing and opening plate 1212 continues to drive the energy storage element 122 to store energy under the action of external force until the energy storage element 122 moves to the energy storage position and abuts against the locking assembly 150.

When the brake needs to be opened, under the control of a trip signal, the trip assembly drives the locking element 151 to rotate through the action end 154 of the locking element 150, so that the energy storage element 122 and the abutting portion 152 are released from abutting, and at this time, the opening and closing plate 1212 releases energy under the driving of the energy storage element 122, i.e., moves toward the brake opening direction. In the process of releasing energy from the energy storage element 122 and driving the switching-on/off plate 1212 to move toward the switching-off direction, since the chuck 140 is clamped with the switching-on limiting portion 1021 of the base 100 at the switching-on position through the jaws 141, the switching-on/off energy storage protrusion 1215 of the switching-on/off plate 1212 drives the elastic element 130 to store energy in a deformation manner (opposite to the deformation energy storage direction during switching-on), and simultaneously, the switching-on/off plate 1212 rotates relative to the chuck 140, after the energy is stored in the elastic element 130, the switching-off protrusion edge 1213 of the switching-on/off plate 1212 moves to the switching-off jaw 141 of the chuck 140, slides along the guide wall, and presses the switching-off jaw 141 to deform while sliding, when the switching-on/off plate 1212 moves to the switching-off dead point position, the switching-off jaw 141 and the switching-on limiting portion 1021 of the upper cover 102 just release energy (release a limit along the switching-off rotating direction), and the chuck 140 rotates toward the switching-off position under the release energy of the elastic element 130, that is, i.e., toward the switching-off limiting portion 1022 of the upper cover 102, then, the contact device 200 is driven to move towards the opening direction, and when the chuck 140 moves to the opening limiting part 1022 of the upper cover 102 and the opening limiting part 1022 is located in the accommodating space 142 between the two claws 141, the contact device 200 completes the closing.

As shown in fig. 10, when the chuck 140 is at the closing position, the closing limiting part 1021 is located in the accommodating space 142 between the two jaws 141 of the chuck 140, and is clamped and limited by the two jaws 141. As shown in fig. 11, the energy storage assembly 120 is at the opening dead point position, that is, the opening protrusion edge 1213 on the opening and closing plate 1212 of the energy storage assembly 120 drives the opening claw 141 of the chuck 140 to deform, so that the chuck 140 and the base 100 are released from the engagement of the movement in the opening direction.

Optionally, before the energy storage assembly 120 is located at the opening dead point, the force value of the energy storage assembly 120 is greater than the sum of the force value of the elastic member 130 and the force value of the resistance, so that the energy storage assembly 120 can smoothly move to the opening dead point, the whole mechanism can be reliably opened, and the opening safety is further improved. It should be noted that the above-mentioned resistance includes, but is not limited to, the friction force received during the energy storage assembly 120 releasing energy, the force required to press the claw 141 to deform to release the engagement with the base 100, and the like.

As shown in fig. 12, the straight line b is a graph showing the change of the force value F of the sum of the elastic member and the resistance force during the movement of the energy storage assembly from the energy storage holding position m toward the opening dead point position n. As can be known from the graph 12, in the process of the energy storage assembly moving towards the opening dead point position n from the energy storage position m, the force value F of the energy storage assembly is gradually reduced, and the force value F of the sum of the elastic piece and the resistance is gradually increased, so that before the opening dead point position, when the force value of the energy storage assembly is larger than the force value of the sum of the elastic piece and the resistance, the energy storage assembly can move to the opening dead point position, the whole mechanism is reliably opened, and the opening safety is improved. It should be noted that, in the opening dead point position, two situations should be included, and the force value of the energy storage assembly is greater than or equal to the force value of the sum of the elastic member and the resistance.

Optionally, when the energy storage assembly 120 is located at the opening dead point, the force value of the energy storage assembly 120 is 110% to 200% (including the end point) of the force value of the elastic member 130, so that the energy storage assembly 120 has a certain margin, and the opening reliability of the mechanism is improved. In some embodiments, when the energy storage assembly 120 is located at the opening dead point, the force value of the energy storage assembly 120 may be 120% to 150% of the force value of the elastic member 130, so that the opening of the mechanism can be further reliably achieved, and meanwhile, the mechanism loss caused by a large impact on the mechanism due to an excessively large force value of the energy storage assembly 120 can be effectively avoided. Of course, in other embodiments, the force value of the energy storage assembly 120 may also be 110% to 120% or 150% to 200% of the force value of the elastic member 130 when the energy storage assembly 120 is located at the opening dead center position.

Optionally, the energy storage assembly 120 is rotatably disposed on the base 100, and a rotation angle of the energy storage assembly 120 from the energy storage holding position to the opening dead point position is 70 degrees to 87 degrees, so that the lengths of the movement paths of the energy storage assembly 120 are all suitable, untimely opening caused by too long path is avoided, and meanwhile, too short path is avoided, and the opening speed of the mechanism is slow due to insufficient energy storage of the elastic member 130. In some embodiments, the rotation angle of the energy storage assembly 120 from the energy storage maintaining position to the opening dead point position may be 75 degrees to 85 degrees, so as to further balance the path length.

Optionally, as shown in fig. 1, the electronic device further includes a signaling device disposed on the base 100, the signaling device may be located in the mounting box 103, and as shown in fig. 7, a triggering portion 1217 is disposed on the separating plate 1212 of the energy storage assembly 120, when the energy storage assembly 120 moves to the position where the energy storage is maintained and abuts against the locking assembly 150 (the entire mechanism has completed closing), at this time, the energy storage assembly 120 triggers the signaling device, the signaling device may be connected to an external controller through a circuit board and a connection terminal disposed in the mounting box 103, and the controller obtains a signal indicating that the closing is in place. Similarly, when the brake needs to be opened, the energy storage assembly 120 leaves the energy storage holding position, that is, the triggering portion 1217 also leaves the signaling device, and the signaling device is not triggered, at this time, the controller can acquire a signal that the energy storage assembly 120 leaves the energy storage holding position. Thus, safety can be improved.

On the other hand, as shown in fig. 1 and fig. 2, the rotary switch includes a contact device 200 and any one of the above energy storage tripping devices, where the contact device 200 may include multiple phase housings, the multiple phase housings may be spliced to form a whole, and a moving contact and a static contact that are matched with each other are disposed inside each phase housing, where the moving contact is in driving connection with a chuck 140 of the energy storage tripping device, so that, in a process of driving the energy storage assembly 120 to move to a position where energy is stored and to abut against the latching assembly 150 through an external force, the chuck 140 drives the contact device 200 to be in a closing state; when the brake needs to be opened, the tripping component drives the locking component 150 to release the clamping with the energy storage component 120, and further in the process of releasing the energy of the energy storage component 120, because the chuck 140 is still clamped with the base 100 at the brake closing position, the energy storage component 120 can drive the elastic component 130 to store energy first, after the energy is stored in the elastic component 130, along with the continuous energy release of the energy storage component 120, the energy storage component 120 drives the chuck 140, so that the chuck 140 and the base 100 are released from the clamping at the brake closing position, at this moment, the elastic component 130 after storing energy starts to release energy and drives the moving contact to move towards the brake opening direction through the chuck 140 until the chuck 140 moves to the brake opening position, and the moving contact is also located at the brake opening position. In some embodiments, the multiple-phase moving contacts may form a linkage relationship, so that the opening and closing motions of the chuck 140 may drive the moving contacts in the multiple-phase housing to open and close together.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
