The present disclosure relates to the field of electrical technologies, and in particular, to an energy storage status monitoring structure and a rotary switch.
A switch refers to an element that enables a circuit to be opened, enables a current to be interrupted, or enables a current to flow to another circuit. In the history of switches, a switch evolved from an original knife switch that requires a manual operation to a current intelligent switch that is used in various large electrical control devices. The switch has more functions and higher safety.
With development of technologies, switches are widely used in increasing control fields or automation fields, such as fields of electric power, machinery, mines, metallurgy, petrochemical, architecture, shipping, nuclear power, and new energy power generation. During use, a power supply often needs to be cut off in an emergency. In a relatively quick power supply cut-off mode, an energy storage assembly cooperates with a release assembly, and the energy storage assembly releases energy to drive a switch to perform a switch-off operation.
However, the energy storage assembly may have not completed energy storage when a power supply needs to be remotely cut off. Consequently, during remote control, the energy storage assembly cannot be remotely controlled to release energy to drive the switch to perform the switch-off operation, affecting a normal remote operation.
The present disclosureprovides an energy storage status monitoring structure and a rotary switch, to monitor an energy storage status of an energy storage assembly, thereby improving reliability of remote control.

Optionally, the energy storage tray further includes a second protrusion. The turntable includes a stopper. The stopper is located in a storage slot of the turntable. A second elastic member is disposed in the storage slot, and the second elastic member abuts against each of the second protrusion and the stopper.

Beneficial effects of embodiments of the present disclosure include:
According to the status monitoring structure and the rotary switch provided in embodiments of the present disclosure, by using the upper cover of the operation mechanism, the rotating shaft rotatably connected to the upper cover, and the energy storage tray connected to the rotating shaft, the energy storage assembly is enabled to accumulate elastic potential energy during rotation of the energy storage tray, because the energy storage assembly is connected to the energy storage tray. When accumulation of the elastic potential energy is completed, the sensing portion of the energy storage tray corresponds to the sensing component, so that the sensing component outputs the corresponding sensing signal, to ensure that the energy storage spring completes energy storage. Therefore, during remote control, the energy storage spring can be remotely controlled to release energy to drive the switch to perform a switch-off operation, thereby improving reliability of remote control.

For example, a connection may be a fixed connection, a removable connection, or an integral connection; may be a mechanical connection or an electrical connection; may be a direct connection or an indirect connection via a medium; or may be an internal connection between two components.

A status monitoring structure provided in an embodiment is mainly applied to a rotary switch, to improve reliability of remote control by monitoring an energy storage status of an energy storage assembly in the rotary switch. In this embodiment, the rotary switch is used as an example for detailed description.
As shown in
For example, when the sensing portion 1162 is located in different locations, the sensing component 132 outputs different signals. As shown in
It should be noted that a form of a connection between the rotating shaft 114 and the energy storage tray 116 is not specifically limited in this embodiment, provided that a required transmission requirement and a stable connection can be met. For example, the rotating shaft 114 and the energy storage tray 116 may use a form of a fixed connection, such as riveting, welding, or integral molding, or may use a form of an assembly connection, such as a sleeved connection, a clamped connection, or a screwed connection.
According to the status monitoring structure provided in this embodiment of the present disclosure, by using the upper cover 112 of the operation mechanism 110, the rotating shaft 114 rotatably connected to the upper cover 112, and the energy storage tray 116 connected to the rotating shaft 114, the energy storage assembly 120 is enabled to accumulate elastic potential energy during rotation of the energy storage tray 116, because the energy storage assembly 120 is connected to the energy storage tray 116. When accumulation of the elastic potential energy is completed, the sensing portion 1162 of the energy storage tray 116 corresponds to the sensing component 132, so that the sensing component 132 outputs a corresponding sensing signal, to ensure that the energy storage spring 124 completes energy storage. Therefore, during remote control, the energy storage spring 124 can be remotely controlled to release energy to drive the switch to perform a switch-off operation, thereby improving reliability of remote control.
The sensing component 132 in this embodiment may be any one of a micro switch, a travel switch, or a proximity switch, provided that output of a required sensing signal can be ensured. In actual application, the sensing component 132 can be flexibly selected based on an actual disposing location and a size of space.
As shown in
Specifically, a disposing location of the energy storage spring 124 is not specifically limited in this embodiment of this application. For example, the energy storage spring 124 may be sleeved on the rotating shaft 114, or may be disposed in an accommodation space of the upper cover 112, as long as it can be ensured that one end of the energy storage spring 124 is clamped to the upper cover 112, and the other end thereof is clamped to the energy storage tray 116, to provide required elastic potential energy by using the energy storage spring 124.
When relative rotation occurs between the rotating shaft 114 and the upper cover 112 by using the energy storage spring 124 clamped to each of the energy storage tray 116 and the upper cover 112, the energy storage tray 116 synchronously rotates with the rotating shaft 114, to drive the energy storage spring 124 to be elastically deformed, so that the energy storage spring 124 accumulates elastic potential energy. The lock 122 is hinged to the upper cover 112, so that the lock 122 can rotate along a hinge part. In addition, during a rotation process of the energy storage tray 116, when the energy storage spring 124 is driven to be elastically deformed, the energy storage spring 124 is clamped to the lock 122, thereby maintaining the elastic potential energy accumulated by the energy storage spring 124. When the energy storage spring 124 stores energy and is clamped to the lock 122, the sensing portion 1162 of the energy storage tray 116 corresponds to the sensing component 132, so that the sensing component 132 outputs the corresponding sensing signal, to ensure that the energy storage spring 124 completes energy storage.

In the foregoing disposing form, not only stability of the energy storage spring 124 during use can be ensured, but also cooperation between the energy storage spring 124, the upper cover 112, and the rotating shaft 114 can be more compact to fully utilize an internal space. This helps implement miniaturization of the rotary switch 100.
As shown in
As shown in
For example, the release 134 is any one of a magnetic flux converter, a separate release, an undervoltage release, or an overvoltage release. An action of the release 134 is controlled by using an electrical signal, so that the lock 122 releases limitation on the energy storage spring 124, and the rotary switch 100 is enabled to rapidly respond, to implement a remote switch-off function.
Still referring to
The release 134 is configured to receive a control signal, and acts based on the control signal, for example, apply an acting force to the release portion, so that the release portion 1223 moves away from a location of the release 134. In a process in which the release portion 1223 moves away from the release 134, relative rotation occurs between the hinge portion 1221 of the lock 122 and the upper cover 112, so that a location of the limiting portion 1222 of the lock 122 moves, the second torsion arm 1246 of the energy storage spring 124 is no longer limited, and the energy storage spring 124 can recover from elastic deformation and drive the energy storage tray 116 to rotate reversely, to enable the energy storage tray 116 to rotate to a switch-off location, thereby completing a switch-off operation.
As shown in
For example, when the first elastic member 126 is disposed between the lock 122 and the upper cover 112, the first elastic member 126 may be in a form of a compression spring, a spring plate, or the like, so that there is a repulsion force between the lock 122 and the upper cover 112, and the release portion 1223 has the tendency to move toward the release 134. When the first elastic member 126 is disposed between the lock 122 and the mounting base 118, the first elastic member 126 may be in a form of an extension spring, an elastic rope, or the like, so that the release portion 1223 has the tendency to move toward the release 134, and it is ensured that the limiting portion 1222 can stably limit the second torsion arm 1246 of the energy storage spring 124.
In addition, still referring to
Referring to
As shown in
When the release 134 receives a release signal, the release 134 acts, so that the release portion 1223 overcomes an acting force of the first elastic member 126 and moves away from the location of the release 134. In a movement process of the release portion 1223, a limiting amount of the limiting surface 1225 on the second torsion arm 1246 of the energy storage spring 124 gradually decreases, until the second torsion arm 1246 is relieved from the limiting action of the limiting portion 1222. After the second torsion arm 1246 is relieved from the action of the limiting portion 1222 of the lock 122, the elastic potential energy accumulated by the energy storage spring 124 is released. By using the first protrusion 1164, the energy storage tray 116 is driven to rotate to the switch-off location, so that the rotary switch 100 is switched off.
As shown in
When the second torsion arm 1246 needs to be separated from the limiting portion 1222 to implement energy release of the energy storage spring 124, an external force may be applied to the release portion 1223 of the lock 122, thereby driving the lock 122 to rotate in a direction away from the second torsion arm 1246. The limiting surface 1225 includes a barrier surface and a transition surface that are connected to each other. As shown in
When the transition surface of the limiting portion 1222 abuts against the second torsion arm 1246, the acting force applied by the second torsion arm 1246 to the transition surface is used to enable the lock 122 to generate a rotation moment, so that the lock 122 and the second torsion arm 1246 have a tendency to move away from each other. As shown in
As shown in
In addition, as shown in
As shown in
For example, the rotating shaft 114 is disposed by passing through the upper cover 112, and extends to a location of the mounting base 118. The energy storage tray 116 connected to the rotating shaft 114 is located in the location of the mounting base 118. When rotating, the rotating shaft 114 drives, by using the energy storage tray 116, the turntable 119 to rotate, to control switch-off or switch-on of the rotary switch 100. Because the turntable 119 rotates in the mounting groove 1182, an outer circle of the turntable 119 and an inner circle of the mounting groove 1182 are circular, so as to facilitate relative rotation.
As shown in
For example, when rotating, the rotating shaft 114 drives, by using the energy storage tray 116, the second elastic member 117 to be elastically deformed, and an elastic force generated when the second elastic member 117 recovers from the elastic deformation causes the turntable 119 to rotate, so as to drive, by using the turntable 119, the rotary switch 100 to be switched off or switched on. It should be noted that the second elastic member 117 is not specifically limited in this application, provided that a required transmission force for switch-off or switch-on can be met. For example, the second elastic member 117 may be a torsion spring, a mainspring, or another elastic member. In a process in which the rotating shaft 114 rotates to enable the energy storage spring 124 to store energy and simultaneously drives the second elastic member 117 to be elastically deformed, the second elastic member 117 drives the turntable 119 to rotate, so that the rotary switch 100 is switched on. In addition, in an energy release process of the energy storage spring 124, the second elastic member 117 also recovers from elastic deformation to perform work, to drive the turntable 119 to rotate back and forth, so that the rotary switch 100 is switched off.
As shown in
For example, in a process in which the rotating shaft 114 is manually operated to rotate, to enable the energy storage spring 124 to store energy and drive the rotary switch 100 to be switched on, the energy storage tray 116 synchronously rotates along with the rotating shaft 114. At an initial moment at which the energy storage tray 116 rotates, the sensing portion 1162 moves toward the first pawl 1194. As the rotation continues, the sensing portion 1162 abuts against the first pawl 1194 (as shown in
Similarly, in a process of remotely controlling switch-off, the release 134 acts to enable the lock 122 to release limitation on the energy storage spring 124. The elastic potential energy accumulated by the energy storage spring 124 is released in a switch-of process, to drive the rotating shaft 114 to rotate back and forth. The energy storage tray 116 synchronously rotates along with the rotating shaft 114, and the pushing portion 1168 moves toward the second pawl 1196. As the rotation continues, the pushing portion 1168 abuts against the second pawl 1196 and continues to push forward, until the pushing portion 1168 presses against the second pawl 1196 and the second pawl 1196 deforms in a direction toward the second gap 1199. In a process in which the second pawl 1196 is pressed against by the pushing portion 1168 and deformed, the end face of the second pawl 1196 and the second limiting protrusion 1128 are staggered, so that the turntable 119 can continuously rotate, to implement a purpose of switching off the rotary switch 100. When the rotary switch 100 completes switch-off, the preset space 1197 between the end face of the first pawl 1194 and the end face of the second pawl 1196 corresponds to the first limiting protrusion 1126, so that rotation of the turntable 119 can be driven by only the operation mechanism 110, and an accidental action of the rotary switch 100 is prevented. This helps ensure state stability of the rotary switch 100.
It should be noted that, while pushing the first pawl 1194 to enable the first pawl 1194 to be deformed, the sensing portion 1162 can also cooperate with the sensing component 132 to enable the sensing component 132 to output the sensing signal. During rotation, the sensing portion 1162 has a larger radius than the pushing portion 1168, so that the sensing portion 1162 can cooperate with the sensing component 132, and other parts do not interfere with the sensing component 132.
As shown in
For example, in a process in which the rotating shaft 114 is manually operated to rotate, the energy storage tray 116 rotates, so that the second elastic member 117 is elastically deformed. As the rotation continues, the sensing portion 1162 abuts against the first pawl 1194 and continues to push forward, and an elastic deformation amount continues to increase, until the sensing portion 1162 presses against the first pawl 1194 to deform in the direction toward the first gap 1198, so that the first pawl 1194 goes beyond the first limiting protrusion 1126. After the first pawl 1194 goes beyond the first limiting protrusion 1126, the first limiting protrusion 1126 no longer plays a role of limiting the turntable 119, and the second elastic member 117 drives, by using the stopper 1192, the turntable 119 to switch on the rotary switch 100. Similarly, in a process of remotely controlling switch-off, the elastic potential energy accumulated by the energy storage spring 124 is released, to drive the rotating shaft 114 to rotate back and forth. The energy storage tray 116 synchronously rotates along with the rotating shaft 114, and the pushing portion 1168 abuts against the second pawl 1196 and continues to push forward, until the pushing portion 1168 presses against the second pawl 1196 and the second pawl 1196 deforms in the direction toward the second gap 1199. In a process in which the second pawl 1196 is pressed against by the pushing portion 1168 and deformed, the end face of the second pawl 1196 and the second limiting protrusion 1128 are staggered, so that the second elastic member 117 drives, by using the stopper 1192, the turntable 119 to rotate back and forth, to implement a purpose of switching off the rotary switch 100.
As shown in
For example, after the release 134 strikes the release portion 1223, the release 134 needs to be reset by using an external force. By pressing against the pressing portion 1382 of the reset button 138, the support portion 1384 applies a force to reset the release 134. By using the clamping portion 1386 disposed on the support portion 1384 and the blocker 1362 disposed in the housing 136, the reset button 138 can be limited, to avoid a loss of the reset button 138. This helps ensure connection stability.

As shown in
For example, the dynamic contact component 142 is connected to the turntable 119 by using a coupler 146, and the turntable 119 is connected to the energy storage tray 116 by using the second elastic member 117, so that the energy storage tray 116 drives the dynamic contact component 142 to reach contact with or be separated from the static contact component 144.

The foregoing are merely preferred examples of the present disclosure and are not intended to limit the present disclosure, and various changes and modifications may be made to the present disclosure by a person skilled in the art. Any modification, equivalent replacement, or improvement made without departing from the principle of the present disclosure shall fall within the protection scope of the present disclosure.
