Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/CN2021/100124, filed on Jun. 15, 2021, which claims priority to Chinese Patent Application No. 202010702832.3, filed on Jul. 20, 2020. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the field of electrical technologies, and in particular, to an energy storage status monitoring structure and a rotary switch. 
     BACKGROUND 
     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. 
     SUMMARY 
     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. 
     Embodiments of the present disclosure are implemented as follows: 
     According to an aspect of embodiments of the present disclosure, an energy storage status monitoring structure is provided, including an operation mechanism, an energy storage assembly, and a release assembly. The operation mechanism includes an upper cover, a rotating shaft rotatably connected to the upper cover, and an energy storage tray connected to the rotating shaft. The energy storage assembly is connected to the energy storage tray. A sensing portion is disposed on the energy storage tray. A sensing component is disposed on the release assembly. When the energy storage tray rotates to enable the energy storage assembly to store energy, the sensing portion corresponds to the sensing component, so that the sensing component outputs a corresponding sensing signal. 
     Optionally, the sensing component is any one of a micro switch, a travel switch, or a proximity switch. 
     Optionally, the energy storage assembly includes a lock, and an energy storage spring clamped to the energy storage tray and the upper cover. Rotating the energy storage tray enables the energy storage spring to store energy and be clamped to the lock.

     Optionally, a first elastic member is further disposed on the lock, and the operation mechanism further includes a mounting base connected to the upper cover. The first elastic member is disposed between the lock and the upper cover, or the first elastic member is disposed between the lock and the mounting base, so that the release portion has a tendency to move toward the release. 
     Optionally, a mounting groove is disposed in the mounting base, and a turntable is disposed in the mounting groove. The turntable is configured to connect the energy storage tray to an on/off assembly of the rotary switch, so that the energy storage tray controls, by using the turntable, switch-off or switch-on of the rotary switch. 
     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. When rotating, the energy storage tray drives, by using the second elastic member, the turntable to rotate, to enable the rotary switch to be switched off or switched on. 
     Optionally, the release assembly further includes a housing and a reset button disposed on the housing. The reset button includes a pressing portion and a support portion connected to the pressing portion. A clamping portion is disposed on the support portion, and is configured to be clamped to a blocker in the housing for limiting.

     Optionally, an elastic reset member is disposed between the pressing portion and the housing, so that the reset button has a tendency to move toward the release. 
     According to another aspect of embodiments of the present disclosure, a rotary switch is provided, including the energy storage status monitoring structure according to any one of the foregoing implementations, and the on/off assembly connected to the operation mechanism in the energy storage status monitoring structure. The on/off assembly includes a static contact component and a dynamic contact component that is connected to the energy storage tray of the operation mechanism through transmission. 
     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.

     DESCRIPTION OF EMBODIMENTS 
     To make the objectives, technical solutions, and advantages of embodiments of the present disclosure clearer, the following clearly describes the technical solutions in embodiments of the present disclosure with reference to the accompanying drawings in embodiments of the present disclosure. It is clear that the described embodiments are some but not all of embodiments of the present disclosure. Generally, components of embodiments of the present disclosure described and shown in the accompanying drawings may be arranged and designed in various manners. 
     Therefore, the following detailed description of embodiments of the present disclosure in the accompanying drawings is not intended to limit the protection scope of the present disclosure, but merely represent selected embodiments of the present disclosure. Other embodiments obtained by a person of ordinary skill in the art based on embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. 
     It should be noted that similar reference signs and letters represent similar items in the accompanying drawings below. Therefore, once an item is defined in one drawing, it does not need to be further defined and described in subsequent drawings. In addition, the terms such as “first” and “second” are used only for distinguishing descriptions and cannot be understood as an indication or implication of relative importance. 
     In the description of the present disclosure, it should be further noted that, unless otherwise specified and defined explicitly, the terms “arrangement” and “connection” should be understood broadly. 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 person of ordinary skill in the art can understand specific meanings of the foregoing terms in the present disclosure based on a specific situation. 
     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  FIG.  1   , a rotary switch  100  in this embodiment includes an energy storage status monitoring structure. The energy storage status monitoring structure includes an operation mechanism  110 , an energy storage assembly  120 , and a release assembly  130 . The operation mechanism  110  includes an upper cover  112 , a rotating shaft  114  rotatably connected to the upper cover  112 , and an energy storage tray  116  connected to the rotating shaft  114 . The energy storage assembly  120  is connected to the energy storage tray  116 . A sensing portion  1162  is disposed on the energy storage tray  116 . A sensing component  132  is disposed on the release assembly  130 . When the energy storage tray  116  rotates to enable the energy storage assembly  120  to store energy, the sensing portion  1162  corresponds to the sensing component  132 , so that the sensing component  132  outputs a corresponding sensing signal. 
     For example, when the sensing portion  1162  is located in different locations, the sensing component  132  outputs different signals. As shown in  FIG.  2   , when the sensing portion  1162  deviates from a location corresponding to the sensing component  132 , the sensing portion  1162  cannot trigger the sensing component  132  to have a signal change, and the sensing component  132  outputs a first signal. As shown in  FIG.  3   , when the sensing portion  1162  corresponds to the sensing component  132 , the sensing portion  1162  triggers the sensing component  132  to act, so that the sensing component  132  outputs a second signal. Because the first signal is different from the second signal, when the second signal is received, it is considered that the energy storage tray  116  drives an energy storage spring  124  to complete energy storage, and the energy storage spring  124  is clamped to a lock  122 , thereby providing a guarantee for subsequent remote control of switch-off. 
     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  FIG.  1   , the energy storage assembly  120  includes the lock  122  hinged to the upper cover  112 , and the energy storage spring  124  clamped to each of the energy storage tray  116  and the upper cover  112 . Rotating the energy storage tray  116  enables the energy storage spring  124  to store energy and be clamped to the lock  122 . 
     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. 
     As shown in  FIG.  4    and  FIG.  5   , the energy storage tray  116  further includes a first protrusion  1164 . The energy storage spring  124  includes an energy storage body  1242 , and a first torsion arm  1244  and a second torsion arm  1246  that are connected to the energy storage body  1242 . The first torsion arm  1244  is clamped to the upper cover  112 , and the second torsion arm  1246  abuts against the first protrusion  1164 . 
     For example, still referring to  FIG.  6   , a limiting groove  1122  is disposed on the upper cover  112 , and the first torsion arm  1244  of the energy storage spring  124  is clamped to the upper cover  112  through the limiting groove  1122 . In this way, a location between the first torsion arm  1244  of the energy storage spring  124  and the upper cover  112  may be relatively fixed, which helps improve stability of the energy storage spring  124  during use, and ensures that the energy storage spring  124  can store energy normally. In addition, by using the second torsion arm  1246  and the first protrusion  1164  of the energy storage tray  116  in a process of recovery from elastic deformation, the energy storage tray  116  is driven to rotate, which helps improve stability during switch-off. 
     Still referring to  FIG.  6   , a hollow pillar  1124  is further disposed on the upper cover  112 . The rotating shaft  114  passes through the hollow pillar  1124 , and is rotatably connected to the upper cover  112 . Specifically, the rotating shaft  114  is connected to an inner side and an outer side of the upper cover  112 , to perform an interactive operation with the rotary switch  100  by using the rotating shaft  114 . The rotating shaft  114  is disposed by passing through the hollow pillar  1124 , so that smoothness of rotation of the rotating shaft  114  can be improved, and the rotating shaft  114  is prevented from shaking in a radial direction, thereby improving precision and stability during rotatable connection. In addition, the energy storage body  1242  may be sleeved on an outer circle of the hollow pillar  1124 . This can limit the energy storage spring  124 , to prevent a lateral deviation of the energy storage spring  124  and impact on clamping between the first torsion arm  1244  of the energy storage spring  124  and the upper cover  112 . In addition, it can also be ensured that the second torsion arm  1246  of the energy storage spring  124  is clamped to and abuts against the first protrusion  1164  of the energy storage tray  116 , to avoid misalignment and impact on energy storage of the energy storage spring  124 . In addition, this also enables the second torsion arm  1246  of the energy storage spring  124  to better cooperate with the lock  122 , to avoid accidental separation of the second torsion arm  1246  from the lock  122  that is caused by shaking of the energy storage spring  124  and avoid affecting energy storage of the energy storage spring  124 . 
     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  FIG.  1   ,  FIG.  4   , and  FIG.  6   , a ring groove  1142  is disposed on the rotating shaft  114 . A sealing ring is disposed on an outer circle of the ring groove  1142 , so that locations of the sealing ring and the rotating shaft  114  are relatively fixed. The sealing ring is located between the rotating shaft  114  and the hollow pillar  1124  of the upper cover  112 . When the rotating shaft  114  passes through the upper cover  112  and is rotatably connected to the upper cover  112 , the sealing ring can play a sealing function to enhance sealing performance of the rotary switch  100 . A knob  111  is further disposed on the rotating shaft  114 , and the knob  111  is located at an end of the rotating shaft  114  that is away from a transmission member. In addition, the knob  111  is further disposed on the rotating shaft  114 , and the knob  111  is located at the end of the rotating shaft  114  that is away from the transmission member. With the knob  111  disposed on the rotating shaft  114 , manually operating the rotary switch  100  is more laborsaving and more convenient. 
     As shown in  FIG.  1    and  FIG.  7   , the release assembly  130  further includes a release  134 , and the lock  122  includes a hinge portion  1221  hinged to the upper cover  112 , a limiting portion  1222  configured to limit the second torsion arm  1246 , and a release portion  1223  cooperating with the release  134 . 
     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  FIG.  6   , further, a hinged support  1125  is correspondingly disposed on the upper cover  112 , and the hinge portion  1221  of the lock  122  is connected to the hinged support  1125 . Referring to  FIG.  4    and  FIG.  7   , when the rotating shaft  114  enables the energy storage tray  116  to synchronously rotate with the rotating shaft  114 , the first protrusion  1164  of the energy storage tray  116  pushes the second torsion arm  1246  of the energy storage spring  124  to move along with the energy storage tray  116 . In addition, the first torsion arm  1244  of the energy storage spring  124  is clamped to the upper cover  112 , so that the energy storage spring  124  is elastically deformed during movement of the energy storage tray  116 , thereby generating elastic potential energy. In a process in which the first protrusion  1164  of the energy storage tray  116  pushes the second torsion arm  1246  of the energy storage spring  124  to move along with the energy storage tray  116 , the second torsion arm  1246  of the energy storage spring  124  is clamped to the limiting portion  1222 , so that the elastic potential energy generated by the energy storage spring  124  is maintained. When the energy storage spring  124  is limited, the rotating shaft  114  can rotate back and forth, so that the rotary switch  100  is switched off or switched on. In addition, when the energy storage spring  124  is limited by the lock  122  to store energy, and the rotating shaft  114  is rotated to switch on the rotary switch  100 , there is no need to drive the energy storage spring  124  to be elastically deformed, and switch-on is more laborsaving. 
     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  FIG.  1   ,  FIG.  7   , and  FIG.  8   , a first elastic member  126  is further disposed on the lock  122 , and the operation mechanism  110  further includes a mounting base  118  connected to the upper cover  112 . The first elastic member  126  is disposed between the lock  122  and the upper cover  112 , or the first elastic member  126  is disposed between the lock  122  and the mounting base  118 , so that the release portion  1223  has a tendency to move toward the release  134 . 
     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  FIG.  8   , a limiting protrusion  1226  is disposed between the release portion  1223  and the limiting portion  1222 , and the limiting protrusion  1226  cooperates with the mounting base  118  to limit the lock  122 . For example, when the release  134  is restored to a state existing before the action, the lock  122  is under an action of the first elastic member  126 , so that the lock  122  rotates by using the hinge portion  1221 , and the release portion  1223  has the tendency to move toward the release  134 . By using the limiting protrusion  1226  disposed between the release portion  1223  and the limiting portion  1222 , the mounting base  118  limits a movement range of the lock  122  in a process in which the release portion  1223  moves toward the release  134 , to avoid a collision between the release portion  1223  and the release  134 , thereby improving stability of the release  134  during use. 
     Referring to  FIG.  12   , the lock  122  includes a support body  1227 , and the release portion  1223  includes a folding edge  1228  connected to the support body  1227  and a forced portion 12299 connected to the folding edge  1228 . Specifically, there is a preset included angle between a plane on which the folding edge  1228  is located and a plane on which the support body  1227  is located, and the included angle is preferably 90°. In this way, connection strength between the support body  1227  and the release portion  1223  can be improved, to avoid deformation of the lock  122  caused by a force, and improve structural stability of the lock  122 . 
     As shown in  FIG.  7    and  FIG.  8   , a guide surface  1224  is disposed between the hinge portion  1221  and the limiting portion  1222 , a limiting surface  1225  is disposed on a side of the limiting portion  1222  that is away from the guide surface  1224 , and the limiting surface  1225  has an angle of inclination. The angle of inclination may be properly set based on a location of the hinge portion  1221  of the lock  122 . For example, when the rotating shaft  114  drives the energy storage tray  116  to rotate, the first protrusion  1164  on the energy storage tray  116  drives the second torsion arm  1246  to rotate with the energy storage tray  116 . When the second torsion arm  1246  moves, the second torsion arm  1246  abuts against the guide surface  1224 , and moves along the guide surface  1224  toward the location of the limiting portion  1222 . When the second torsion arm  1246  moves to the side of the limiting portion  1222  that is away from the guide surface  1224 , that is, when the second torsion arm  1246  moves to the side of the limiting portion  1222  on which the limiting surface  1225  is disposed, the second torsion arm  1246  is limited by the limiting portion  1222 . Even if the energy storage tray  116  no longer applies an acting force to the second torsion arm  1246 , the second torsion arm  1246  cannot be restored to an initial state, thereby implementing an energy storage operation on the energy storage spring  124 . 
     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  FIG.  9   , when the second torsion arm  1246  abuts against the limiting surface  1225  with the angle of inclination, the second torsion arm  1246  applies an acting force F 1  to the limiting surface  1225  at an abutment location, and an extending direction of the acting force F 1  needs to be located below a connecting line between the abutment location and a hinge location (as shown in  FIG.  9   ). In this case, the acting force F 1  generates a counterclockwise moment M 1  on the lock  122 , so that the lock  122  generates a counterclockwise rotation tendency, thereby strengthening limitation of the limiting surface  1225  on the second torsion arm  1246 , and implementing more stable locking. In this way, the energy storage assembly  120  can still stably maintain an energy storage state under vibration of a specific amplitude. 
     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  FIG.  10   , the lock  122  rotates clockwise under an action of an external force (which may be provided by the release  134 ). In this case, the second torsion arm  1246  gradually switches from the energy storage state to an energy release state. In a switching process, the second torsion arm  1246  slides (relatively moves) from a wall surface that abuts against the barrier surface to the transition surface below the barrier surface. In this case, because the second torsion arm  1246  still stores energy, the second torsion arm  1246  further applies an acting force to the transition surface. Because one end of the lock  122  is hinged to the upper cover  112 , when the acting force acts on the lock  122  (the limiting portion  1222 ), the lock  122  is enabled to generate a tendency to rotate along the hinge portion  1221 . In addition, the rotation tendency is to rotate in a direction away from the second torsion arm  1246 , to facilitate separation between the limiting portion  1222  and the second torsion arm  1246 , so that the energy storage spring  124  can release energy smoothly. In particular, the release  134  is used to apply an external force to the lock  122  to drive the lock  122  to rotate, so that the limiting portion  1222  and the second torsion arm  1246  are separated, thereby implementing energy release of the energy storage spring  124 . A reason is that, due to a structural limitation of the release  134 , a striking force of the release  134  gradually weakens as a distance by which a protruding end of the release  134  extends outward increases. Disposing the transition surface can effectively avoid a phenomenon that the energy storage spring  124  cannot release energy when separation is needed because the striking force of the release  134  weakens in a later stage and consequently the second torsion arm  1246  and the limiting portion  1222  cannot be completely separated. This effectively ensures that energy release can be smoothly and accurately performed when the energy storage spring  124  needs to release energy, and improves control reliability of the rotary switch  100  in this application. 
     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  FIG.  10   , when the lock  122  is a rod assembly, one end of the lock  122  is hinged to the upper cover  112 . In addition, the limiting portion  1222  is disposed below the lock  122 , and the barrier surface and the transition surface are disposed on a side of the limiting portion  1222  that is away from the hinge portion  1221 . The transition surface is located below the barrier surface, and the transition surface has an angle of inclination (the angle of inclination of the transition surface may be the same as or different from that of the barrier surface in the foregoing embodiment). The angle of inclination may be properly set based on the location of the hinge portion  1221  of the lock  122 . 
     As shown in  FIG.  10   , when the second torsion arm  1246  abuts against the transition surface with the angle of inclination, the second torsion arm  1246  applies an acting force F 2  to the barrier surface at an abutment location, and an extending direction of the acting force F 2  needs to be located above a connecting line between the abutment location and a hinge location (as shown in  FIG.  10   ). In this case, the acting force F 2  generates a clockwise moment M 2  on the lock  122 , so that the lock  122  generates a clockwise rotation tendency, to cause separation between the limiting portion  1222  and the second torsion arm  1246 . In this way, the energy storage spring  124  can still smoothly release energy when the striking force is small. When M F   external &gt;M f   resistance +M 1 +M F3 , it can be ensured that the lock  122  rotates along a hinged end under an action of an external force, to drive the barrier surface to move relative to the second torsion arm  1246 , so that the second torsion arm  1246  can slide to the transition surface. When M F   external +M 2 &gt;M f dynamic +M F3 , and other friction forces of a system can be overcome, the lock  122  continues to move to an unlocking (energy release) location. M F   external  refers to an external force applied to the other end of the lock  122  relative to the hinged end, and may be the striking force of the release  134 . When the second torsion arm  1246  abuts against the barrier surface, a friction force is f resistance , which may be a dynamic friction force when the second torsion arm  1246  and the barrier surface move relative to each other, or may be a static friction force when the second torsion arm  1246  and the barrier surface are relatively stationary and have a tendency to move relative to each other. A moment generated corresponding to f resistance  is M f   resistance . Mf  dynamic  is a moment generated corresponding to the dynamic friction force f dynamic  when the second torsion arm  1246  slides on the transition surface. M F3  is a moment of an acting force F 3  applied by the first elastic member  126  to the lock  122 . If a value of M 2  is set to M 2 &gt;M f   dynamic +M F3 , it is only necessary to ensure that the release  134  can drive the second torsion arm  1246  to slide to the transition surface, and then reliable release can be ensured. That is, provided that the striking force F external  provided by the release  134  can drive the lock  122  to implement contact between the second torsion arm  1246  and the transition surface, reliable release can be ensured. 
     In addition, as shown in  FIG.  11   , when the rotary switch  100  is subject to external vibration, the limiting portion  1222  gradually moves slowly from a locking location (the energy storage state of the energy storage spring  124 ) to an unlocking location (the energy release state of the energy storage spring  124 ) under an external vibration force. When the transition surface abuts against the second torsion arm  1246  of the energy storage spring  124 , a friction force generated on the limiting portion  1222  is f static  (f static =µ static ×F 2 , and µ static  is a static friction factor on the transition surface; f dynamic =µ dynamic ×F 2 , and µ dynamic  is a dynamic friction factor on the transition surface; F 2  is an acting force applied to the transition surface by the second torsion arm  1246  of the energy storage spring  124 ; and because µ static  is much greater than µ dynamic , f static  is much greater than f dynamic ), and a generated moment is M f   static . When M 2 &lt;M f   static , it can still be ensured that the energy storage spring  124  remains in the energy storage state. When the first elastic member  126  is included, M 2 &lt;M f   static +M F3 , it can still be ensured that the energy storage spring  124  remains in the energy storage state. Therefore, disposing the transition surface can further improve an anti-interference capability of the rotary switch  100  in this application, that is, further increase an upper limit for a misoperation of the rotary switch  100  caused by vibration. 
     As shown in  FIG.  13    and  FIG.  14   , a mounting groove  1182  is disposed in the mounting base  118 , and a turntable  119  is disposed in the mounting groove  1182 . The turntable  119  is configured to connect the energy storage tray  116  to an on/off assembly  140  of the rotary switch  100 , so that the energy storage tray  116  controls, by using the turntable  119 , switch-off or switch-on of the rotary switch  100 . 
     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  FIG.  4   ,  FIG.  15   , and  FIG.  17   , the energy storage tray  116  further includes a second protrusion  1166 . The turntable  119  includes a stopper  1192 . The stopper  1192  is located in a storage slot of the turntable  119 . A second elastic member  117  is disposed in the storage slot, and the second elastic member  117  abuts against each of the second protrusion  1166  and the stopper  1192 . When rotating, the energy storage tray  116  drives, by using the second elastic member  117 , the turntable  119  to rotate, so that the rotary switch  100  is switched off or switched on. 
     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  FIG.  4    and  FIG.  14   , a pushing portion  1168  is disposed on the energy storage tray  116 , and the turntable  119  includes a turntable body  1191  and a first pawl  1194  and a second pawl  1196  that are disposed on the turntable body  1191 . The first pawl  1194  and the second pawl  1196  are disposed opposite to each other, and there is a preset space  1197  between an end face of the first pawl  1194  and an end face of the second pawl  1196 . Still referring to  FIG.  6   , a first limiting protrusion  1126  and a second limiting protrusion  1128  are disposed at a corresponding space on the upper cover  112 , and both the first limiting protrusion  1126  and the second limiting protrusion  1128  can be clamped in the preset space  1197 . There is a first gap  1198  between the first pawl  1194  and the turntable body  1191 , and there is a second gap  1199  between the second pawl  1196  and the turntable body  1191 . The sensing portion  1162  can abut against the first pawl  1194 , so that the first pawl  1194  retracts toward the first gap  1198 , and the first limiting protrusion  1126  releases limitation on the first pawl  1194 . The pushing portion  1168  can abut against the second pawl  1196 , so that the second pawl  1196  retracts toward the second gap  1199 , and the second limiting protrusion  1128  releases limitation on the second pawl  1196 . 
     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  FIG.  18   ), and continues to push forward, until the sensing portion  1162  presses against the first pawl  1194  to deform in a direction toward the first gap  1198 . In a process in which the first pawl  1194  is pressed against by the sensing portion  1162  and deformed, the end face of the first pawl  1194  and the first limiting protrusion  1126  are staggered (as shown in  FIG.  19   ), so that the turntable  119  can continuously rotate, to implement a purpose of switching on the rotary switch  100 . When the rotary switch  100  completes switch-on, 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 second limiting protrusion  1128 , so that the turntable  119  is limited and an accidental action of the rotary switch  100  is prevented. This helps ensure state stability of the rotary switch  100 . 
     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  FIG.  4   ,  FIG.  15   , and  FIG.  17   , in an optional embodiment, the second elastic member  117  includes an elastic body  1172  and a first end  1174  and a second end  1176  that are connected to the elastic body  1172 . The first end  1174  abuts against the second protrusion  1166 , and the second end  1176  abuts against the stopper  1192 . 
     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  FIG.  20   , the release assembly  130  further includes a housing  136  and a reset button  138  disposed on the housing  136 . The reset button  138  includes a pressing portion  1382  and a support portion  1384  connected to the pressing portion  1382 . A clamping portion  1386  is disposed on the support portion  1384 , and is configured to be clamped to a blocker  1362  in the housing  136  for limitation. The support portion  1384  is configured to abut against the release  134 , so that the release  134  is reset after action. 
     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. 
     Still referring to  FIG.  20   , an elastic reset member  139  is disposed between the pressing portion  1382  and the housing  136 , so that the reset button  138  has a tendency to move toward the release  134 . In this way, a location of the reset button  138  can be relatively fixed, thereby avoiding random shaking between the reset button  138  and the housing  136 . 
     As shown in  FIG.  1    and  FIG.  21   , the rotary switch  100  provided in this embodiment of the present disclosure further includes the on/off assembly  140  connected to the operation mechanism  110  in the energy storage status monitoring structure. The on/off assembly  140  includes a static contact component  144  and a dynamic contact component  142  that is connected to the energy storage tray  116  of the operation mechanism  110  by transmission. 
     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 . As shown in  FIG.  14   , a connecting hole  1193  (shown in  FIG.  16   ) is correspondingly disposed on the turntable  119 , so that the coupler  146  is connected to the turntable  119 , and the dynamic contact component  142  is also connected to the coupler  146 . Therefore, the dynamic contact component  142  synchronously rotates with the turntable  119 . A connected conductor is disposed on the dynamic contact component  142 . There are two static contact components  144 . A conductor is also disposed on each static contact component  144 . By rotating the dynamic contact component  142 , the conductor on the dynamic contact component  142  is separately connected to the conductors on the two static contacts, to form a path.
