Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a power distribution device. Background Art

[0002] When in use, relays in power distribution equipment typically select the appropriate input source, such as mains power, photovoltaic power generation, or generators, according to the control system's program instructions. If the control system program of the power distribution equipment fails, resulting in incorrect or no relay connection, users will need to wait for technicians to dismantle the power distribution equipment, switch bypass relays, or perform repairs. During this time, users will be unable to use electricity, resulting in long power outages and inconvenience. Utility Model Content

[0003] In view of this, the present application provides a power distribution device to improve the technical problem that the existing power distribution equipment cannot provide power during the communication abnormality maintenance process.

[0004] One embodiment of the present application provides a power distribution device, comprising a relay, a control module, and a switching assembly. The relay is configured to be connected to an input power source; the relay has a mechanical switch configured to move under the action of an external force to control the on / off of the electrical connection between the relay and the input power source. The control module is in communication with the relay and is configured to automatically control the on / off of the electrical connection between the relay and the input power source. The switching assembly is configured to control the on / off of the communication connection between the relay and the control module.

[0005] In the case of abnormal communication between the relay and the control module in this power distribution equipment, the user can use the on-off component to cut off the communication between the relay and the control module, preventing the control module from controlling the relay to connect to the input power. The user can then manually control the relay using a mechanical switch, adjusting the relay to the appropriate position to connect to the corresponding input power, ensuring continuous power supply while the user awaits maintenance.

[0006] In some embodiments of the present application, the on / off assembly includes a toggle switch configured to be movable to a first position or a second position. When the toggle switch is in the first position, the relay communicates with the control assembly. When the toggle switch is in the second position, the communication connection between the relay and the control module is disconnected, thereby disconnecting the control module from controlling the relay.

[0007] In the above embodiment, the user can open and close the communication connection between the relay and the control module by driving the toggle switch to the first position or the second position. The operation is simple and convenient, which is conducive to improving the user experience.

[0008] In some embodiments of the present application, the on / off assembly further includes a knob having a first state and a second state, and the knob is configured to be switchable between the first state and the second state. When the knob is in the first state, the knob is configured to drive the mechanical switch to move to control the on / off electrical connection between the relay and the input power supply. When the knob is in the second state, the knob is configured to drive the toggle switch to move to the first position or the second position.

[0009] In the above embodiment, by integrating the function of communication between the control relay and the control module and the function of connecting the manual adjustment relay to the input power supply into the same component, it is helpful to simplify the operation interface of the power distribution equipment and facilitate user operation and use.

[0010] In some embodiments of the present application, a knob includes a first component and a second component, the first component connected to the second component and movable relative to each other, the first component cooperating with a mechanical switch, and the second component cooperating with a toggle switch. When the knob is in a first state, the first component is configured to control the mechanical switch to connect and disconnect the relay from the input power supply, while the second component avoids the toggle switch. When the knob is in a second state, the second component is configured to drive the toggle switch to move to the first position or the second position.

[0011] In the above embodiment, the knob, through the cooperation of the first and second components, can simultaneously control the communication between the relay and the control module, as well as manually adjust the electrical conduction between the relay and the input power supply. The first component is used to adjust the electrical connection between the relay and the input power supply, while the second component is used to control the communication between the relay and the control module. If either the first or second component is damaged, the user only needs to replace the corresponding component, without having to replace the entire knob, which is cost-effective.

[0012] In some embodiments of the present application, when the knob is in the first state, the first component and the second component are configured to rotate synchronously, and the second component avoids the toggle switch. When the knob is in the second state, the second component is configured to rotate relative to the first component to drive the toggle switch to move.

[0013] In the above embodiment, in the first state, the first and second components rotate synchronously to control the on / off electrical connection between the relay and the input power source. When the knob needs to be switched from the first state to the second state to control the on / off communication between the relay and the control module, this is also achieved by rotation. The operating logic of the knob switching between the two states is consistent, which helps to reduce the difficulty of operating the power distribution equipment and further improve the user experience.

[0014] In some embodiments of the present application, the first component includes a first main body and a first toggle portion connected to the first main body, and the second component includes a second main body and a second toggle portion connected to the second main body. The first and second main bodies are rotatably connected and can rotate synchronously about the same rotation axis. The first toggle portion extends parallel to the rotation axis, and the second toggle portion extends perpendicular to the rotation axis. In a first state, the first main body rotates under the action of an external force, driving the first toggle portion to rotate, thereby actuating the mechanical switch. In a second state, the second main body rotates under the action of an external force, driving the second toggle portion to rotate, thereby actuating the toggle switch.

[0015] In the above embodiment, when the first and second members rotate synchronously, the first toggle portion can drive the mechanical switch to move, thereby controlling the on / off electrical connection between the relay and the input power source. When the second member rotates relative to the first member, the second toggle portion can drive the toggle switch to move, thereby controlling the on / off communication connection between the relay and the control module.

[0016] In some embodiments of the present application, the first toggle portion includes a first active wall and a second active wall arranged at intervals, both of which extend along the direction of the rotation axis, and the mechanical switch is at least partially located between the first active wall and the second active wall; in the first state, the first main body drives the first active wall and the second active wall to rotate synchronously, and drives one of the first active wall and the second active wall to push the mechanical switch.

[0017] In the above embodiment, the gap between the first and second active walls does not directly enclose the mechanical switch, facilitating assembly of the knob. When the knob is mounted on the relay, the mechanical switch is directly inserted into the gap between the first and second active walls to limit the mechanical switch and facilitate actuation of the mechanical switch by the knob.

[0018] In some embodiments of the present application, the switch assembly further includes a stopper having a first stop portion and a second stop portion spaced apart from each other, with the first toggle portion inserted between the first stop portion and the second stop portion. The first stop portion and the second stop portion are both configured to stop the first toggle portion to constrain the rotation angle of the first component.

[0019] In the above embodiment, a stopper is provided to constrain the rotation angle of the first toggle portion, thereby constraining the position of the first member. As the user continues to rotate the second member, the second member rotates relative to the first member. This prevents the first toggle portion from interfering with the mechanical switch and causing damage due to the first member continuing to rotate with the second member when the knob is in the second position.

[0020] In some embodiments of the present application, the second component is provided with a limiting portion, the first component is provided with a limiting hole, and the limiting portion is movably inserted into the limiting hole; the hole wall of the limiting hole is configured to stop the limiting portion when the first component rotates relative to the second component, so as to constrain the rotation range of the first component relative to the second component.

[0021] In the above embodiment, the limiting member and the limiting hole cooperate to limit the rotation range of the second component relative to the first component, thereby reducing the risk of damage to the second toggle part or the toggle switch due to excessive rotation of the second component relative to the first component, thereby extending the service life of the on-off assembly.

[0022] In some embodiments of the present application, the knob also includes a damping member, which is installed between the first component and the second component, and the opposite ends of the damping member respectively conflict with the first component and the second component; when the knob is in the first state, the first component and the second component can rotate synchronously under the action of the damping member.

[0023] In the above embodiment, when the first member is not stopped by the stopper, the first and second members can rotate synchronously under the action of the damping member. When the first member is stopped by the stopper, the user needs to apply a greater force to overcome the damping force to enable the second member to rotate relative to the first member, which helps reduce the risk of the user accidentally shutting down the communication between the relay and the control module.

[0024] In some embodiments of the present application, the damping member includes a first elastic member and a fixed block, one end of the first elastic member abuts against the second member, and the other end is connected to the fixed block, and the fixed block is configured to abut against the first member under the action of the first elastic member.

[0025] In the above embodiment, the damping member is in the form of a combination of a first elastic member and a fixed block, which can reduce the risk of the first member and the second member being unable to switch between the first state and the second state due to assembly errors between the first member and the second member.

[0026] In some embodiments of the present application, the damping member further includes a rolling member, which is disposed between the fixed block and the first component and is rollingly connected to the fixed block and the first component.

[0027] In the above embodiment, the provision of the rolling element can convert the sliding friction between the fixed block and the first component into rolling friction, thereby making the relative rotation of the first component and the second component smoother and reducing the risk of jamming or blocking.

[0028] In some embodiments of the present application, the on-off assembly further includes a reset member, which includes a first connecting segment, a second connecting segment, and a second elastic member. The first connecting segment and the second connecting segment are mounted on the limiting member in an "X" shape, and the first connecting segment and the second connecting segment can rotate relative to each other. The second elastic member is connected to the same end of the first connecting segment and the second connecting segment, respectively. The limiting member is provided with a first protrusion and a second protrusion, the first connecting segment is provided with a first clamping portion, and the second connecting segment is provided with a second clamping portion. When the first component rotates along the first rotation direction, the first action wall pushes the first connecting segment to rotate along the first rotation direction, and the second clamping portion and the second protrusion abut against each other, thereby constraining the position of the second connecting segment. When the first component rotates along the second rotation direction, the second action wall pushes the second connecting segment to rotate along the second rotation direction, and the first clamping portion and the first protrusion abut against each other, thereby constraining the position of the first connecting segment.

[0029] In the above embodiment, when force is applied to rotate the knob, the first and second connecting segments rotate relative to each other under the action of the first toggle portion, causing the second elastic member to elastically deform. When the force applied to the knob is released, the second elastic member drives the first and second connecting segments to rotate relative to each other, automatically returning the knob to its original position, reducing user effort.

[0030] In some embodiments of the present application, the first component is provided with a positioning portion in a direction away from the second component, the limiting member is provided with a positioning groove on a side facing the first component, and the positioning portion is rotatably inserted into the positioning groove.

[0031] In the above embodiment, through the cooperation of the positioning portion and the positioning groove, not only can the relative rotation between the knob and the limit member be achieved, but also the installation efficiency of the knob can be improved, and the risk of the first toggle portion and the mechanical switch being damaged due to the offset of the first component and the limit member along the axial direction can be reduced.

[0056] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0058] When in use, relays in power distribution equipment typically select the appropriate input source, such as mains power, photovoltaic power generation, or generators, according to the control system's program instructions. If the control system program of the power distribution equipment fails, resulting in incorrect or no relay connection, users will need to wait for technicians to dismantle the power distribution equipment, switch bypass relays, or perform repairs. During this time, users will be unable to use electricity, resulting in long power outages and inconvenience.

[0059] Embodiments of the present application provide a power distribution device comprising a relay, a control module, and an on / off assembly. The relay is configured to be connected to an input power source; the relay has a mechanical switch configured to move under the action of an external force to control the on / off of the electrical connection between the relay and the input power source. The control module is in communication with the relay and is configured to automatically control the on / off of the electrical connection between the relay and the input power source. The on / off assembly is configured to control the on / off of the communication connection between the relay and the control module.

[0060] In the case of abnormal communication between the relay and the control module in this power distribution equipment, the user can use the on-off component to cut off the communication between the relay and the control module, preventing the control module from controlling the relay to connect to the input power. The user can then manually control the relay using a mechanical switch, adjusting the relay to the appropriate position to connect to the corresponding input power, ensuring continuous power supply while the user awaits maintenance.

[0061] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0062] An embodiment of the present application provides a power distribution device 100, such as Figures 1 to 3As shown, the power distribution device 100 includes a relay 10, a control module 20, and a switching assembly 30. The relay 10 is configured to be electrically connected to an input power source (not shown), such as any one or more of mains electricity, photovoltaic power, generator, energy storage device, etc.

[0063] The relay 10 has a mechanical switch 11 that is configured to move under an external force to control the on / off connection between the relay 10 and the input power supply. In other words, the user can manually control the electrical connection between the relay 10 and the input power supply through the mechanical switch 11.

[0064] For example, relay 10 is connected to two input power sources: the mains and the energy storage device. When the user controls mechanical switch 11 to move to the mains terminal, the power distribution device 100 is electrically connected to the mains. At this point, the mains power is supplied to the external load to ensure normal power consumption of the external load.

[0065] When the user controls the mechanical switch 11 to move to the generator end, the power distribution device 100 is electrically connected to the generator. At this time, the generator supplies power to the external load to ensure normal power consumption of the external load.

[0066] In some embodiments, the control module 20 is communicatively connected to the relay 10, and the control module 20 is configured to automatically control the on and off of the electrical connection between the relay 10 and the input power supply to achieve intelligent control of the power distribution equipment 100, thereby reducing the user's steps of repeatedly adjusting the mechanical switch 11 and improving the user's usage experience.

[0067] For example, the relay 10 will accurately select one of the mains and the generator for connection according to the program instructions of the control module 20 .

[0068] However, once the control system program of the distribution equipment 100 is abnormal, causing the relay 10 to be connected incorrectly or not connected, it is necessary to wait for technicians to dismantle the distribution equipment 100, switch the bypass relay 10 or repair it. During the technicians' repair period, the user cannot use electricity, resulting in a long-term interruption of electricity use and inconvenience in using electricity.

[0069] In some embodiments, as Figure 3 As shown, the on / off assembly 30 is configured to control the on / off communication connection between the relay 10 and the control module 20. It is understood that when communication between the relay 10 and the control module 20 is abnormal, the user can use the on / off assembly 30 to cut off the communication between the relay 10 and the control module 20, so that the control module 20 cannot control the relay 10 to be electrically connected to the input power supply.

[0070] Afterwards, the user can manually control the relay 10 through the mechanical switch 11, so that the relay 10 is adjusted to a suitable position to connect to the input power supply, thereby ensuring that the user can continue to use electricity while waiting for maintenance.

[0071] In some embodiments, as Figure 4 As shown, the on / off assembly 30 includes a toggle switch 31 that is configured to be movable to a first position or a second position. When the toggle switch 31 is in the first position, the relay 10 is in communication with the control module 20. When the toggle switch 31 is in the second position, the communication connection between the relay 10 and the control module 20 is disconnected, thereby disconnecting the control module 20 from regulating the relay 10.

[0072] By setting the toggle switch 31, the user only needs to drive the toggle switch 31 to move to the first position or the second position to open and close the communication connection between the relay 10 and the control module 20. The operation is simple and convenient, which is conducive to improving the user experience.

[0073] In some embodiments, the toggle switch 31 may be directly exposed on the outside of the power distribution device 100 so that the user can operate the toggle switch.

[0074] In some embodiments, the on / off assembly 30 is provided with a toggle member (not shown), a portion of which is exposed outside the power distribution device 100, and a portion of which extends into the interior of the power distribution device 100 and engages with the toggle switch 31. The user uses the toggle member to move the toggle switch 31, causing the relay 10 to select the corresponding input power source.

[0075] This helps reduce the risk of damage to the toggle switch 31 caused by prolonged operation, protects the toggle switch 31 , and extends the service life of the on-off assembly 30 .

[0076] In some embodiments, as Figure 4 As shown, the on / off assembly 30 further includes a knob 32 having a first state and a second state. The knob 32 is configured to be switchable between the first state and the second state. When the knob 32 is in the first state, the knob 32 is configured to drive the mechanical switch 11 to move, thereby controlling the on / off connection between the relay 10 and the input power supply, thereby achieving manual adjustment of the relay 10.

[0077] When the knob 32 is in the second state, the knob 32 is configured to drive the toggle switch 31 to move to the first position or the second position to control the on / off between the relay 10 and the control module 20 , that is, to realize the start and stop of the intelligent switching function of the relay 10 .

[0078] By integrating the functions of communication between the control relay 10 and the control module 20 and the manual adjustment function of connecting the relay 10 to the input power supply into the same component (specifically the knob 32), it is helpful to simplify the operating interface of the power distribution equipment 100 and facilitate user operation and use.

[0079] In some embodiments, as Figure 4 and Figure 8 As shown, the knob 32 includes a first member 321 and a second member 322. The first member 321 is connected to the second member 322 and can move relative to each other. The first member 321 is limited in position with the mechanical switch 11, and the second member 322 is limited in position with the toggle switch 31.

[0080] Understandably, when the knob 32 is in the first state, the first member 321 is configured to control the operation of the mechanical switch 11 to control the on / off electrical connection between the relay 10 and the input power source, and the second member 322 avoids the toggle switch 31. When the knob 32 is in the second state, the second member 322 is configured to drive the toggle switch 31 to move to the first position or the second position.

[0081] Through the cooperation of the first component 321 and the second component 322, the knob 32 can simultaneously realize the on-off of the communication between the control relay 10 and the control module 20, and manually adjust the on-off of the electrical connection between the relay 10 and the input power supply.

[0082] The first component 321 is used to adjust the electrical connection between the relay 10 and the input power supply, and the second component 322 is used to control the communication between the relay 10 and the control module 20. If either the first component 321 or the second component 322 is damaged, the user only needs to replace the corresponding part, without having to replace the entire knob 32, which is cost-effective.

[0083] It is worth noting that when the knob 32 is in the first state, the second member 322 does not cause the toggle switch 31 to move, which means that the communication connection between the control module 20 and the relay 10 is not cut off. This ensures that if the relay 10 is stuck normally, rather than experiencing some communication anomaly such as a software or program failure, the user can reset the mechanical switch 11 by toggling the knob 32, thereby allowing the power distribution device 100 to operate normally.

[0084] In some embodiments, the second member 322 is rotatable relative to the first member 321. When the knob 32 is in the first state, the first member 321 and the second member 322 are configured to rotate synchronously, with the second member 321 avoiding the toggle switch 31. When the knob 32 is in the second state, the second member 322 is configured to rotate relative to the first member 321 to drive the toggle switch 31 to move.

[0085] For example, when the relay 10 becomes stuck or a software fault is misjudged due to a control program failure, the user rotates the knob 32 to rotate the second member 322 relative to the first member 321. At this point, the second toggle portion 3222 acts on the second toggle switch 31 to cut off the communication connection between the relay 10 and the control module 20.

[0086] After the communication connection between the relay 10 and the control module 20 is severed, the user rotates the knob 32 to synchronize the second member 322 with the first member 321. At this point, the first toggle portion 3212 acts on the mechanical switch 11 to electrically connect the relay 10 to the input power source, thereby ensuring normal power supply to the external load.

[0087] By setting the second component 322 and the first component 321 to be relatively rotatable, the operating logic of the knob 32 switching between the two states can be consistent, which is conducive to reducing the operating difficulty of the power distribution equipment 100 and further improving the user experience.

[0088] In other embodiments, the first member 321 and the second member 322 are relatively slidable. When the knob 32 is in the first state, the first member 321 is configured to toggle the mechanical switch 11 to control the electrical connection between the relay 10 and the input power source. In this state, the second member 322 is configured to avoid the toggle switch 31, that is, the second member 322 does not drive the toggle switch 31 to move.

[0089] When the knob 32 is in the second state, the second member 322 is configured to be raised or lowered a set distance relative to the first member 321. When the user rotates the knob 32, the second member 322 drives the toggle switch 31 to move to the first position or the second position, thereby disconnecting or connecting the communication between the control module 20 and the relay 10.

[0090] In some embodiments, as Figure 4 and Figure 8 As shown, the first member 321 includes a first main body 3211 and a first toggle portion 3212 connected to the first main body 3211 . The second member 322 includes a second main body 3221 and a second toggle portion 3222 connected to the second main body 3221 .

[0091] The first main body 3211 and the second main body 3221 are rotatably connected and can rotate synchronously about the same rotation axis O. The first toggle portion 3212 extends in a direction parallel to the rotation axis O, and the second toggle portion 3222 extends in a direction perpendicular to the rotation axis O. In a first state, the first main body 3211 rotates under the action of an external force, driving the first toggle portion 3212 to rotate, thereby driving the mechanical switch 11 to move. In a second state, the second main body 3221 rotates under the action of an external force, thereby driving the second toggle portion 3222 to rotate, thereby driving the toggle switch 31 to move.

[0092] Understandably, when the first member 321 and the second member 322 rotate synchronously, the first toggle portion 3212 can drive the mechanical switch 11 to move, thereby controlling the on / off electrical connection between the relay 10 and the input power supply. When the second member 322 rotates to a set angle relative to the first member 321, the second toggle portion 3222 can drive the toggle switch 31 to move, thereby controlling the on / off communication connection between the relay 10 and the control module 20.

[0093] In some embodiments, the first actuator 3212 includes a first action wall 3213 and a second action wall 3214 spaced apart from each other. The first action wall 3213 and the second action wall 3214 both extend in a direction parallel to the rotation axis O, and the mechanical switch 11 is at least partially located between the first action wall 3213 and the second action wall 3214.

[0094] In the first state, the first main body 3211 drives the first action wall 3213 and the second action wall 3214 to rotate synchronously, and drives one of the first action wall 3213 and the second action wall 3214 to push the mechanical switch 11 .

[0095] It should be noted that the gap between the first active wall 3213 and the second active wall 3214 does not directly enclose the mechanical switch 11, facilitating assembly of the knob 32. When the knob 32 is mounted on the relay 10, the mechanical switch 11 is directly inserted into the gap between the first active wall 3213 and the second active wall 3214, thereby limiting the position of the mechanical switch 11 and facilitating actuation of the mechanical switch 11 by the knob.

[0096] In some embodiments, as Figures 4 to 6 、 Figure 9 As shown, the switch assembly 30 further includes a stopper 33 having a first stopper 331 and a second stopper 332 spaced apart from each other. The first toggle portion 3212 is inserted between the first stopper 331 and the second stopper 332. The first stopper 331 and the second stopper 332 are configured to stop the first member 321, thereby limiting the rotation angle of the first toggle portion 3212.

[0097] As can be understood, when the user begins to rotate the second member 322, the first and second members 321, 322 rotate synchronously, and the knob 32 is now in the first state. When the first member 321 rotates a certain angle, the first stopper 331 or the second stopper 332 stops the first toggle portion 3212, thereby preventing further rotation of the first member 321. As the user continues to rotate the second member 322, the second member 322 rotates relative to the first member 321. At this point, the knob 32 is in the second state.

[0098] The above-mentioned certain angle specifically refers to the angle between the first stop portion 331 and the second stop portion 332 arranged at intervals. The size of the angle is determined according to the extreme position of the movement of the mechanical switch 11, and those skilled in the art can select it according to actual conditions.

[0099] The provision of the limiting member 33 allows relative rotation between the first member 321 and the second member 322. Furthermore, it prevents the first toggle portion 3212 from interfering with and damaging the mechanical switch 11 due to the first member 321 continuing to rotate along with the second member 322 when the knob 32 is in the second state.

[0100] In some embodiments, the first stopper 331 and the second stopper 332 can directly stop the first toggle portion 3212 to restrict the rotation angle of the first toggle portion 3212. Alternatively, in other embodiments, the first stopper 331 and the second stopper 332 can stop other structures in the first member 321 to indirectly stop the first toggle portion 3212 and restrict the rotation angle of the first toggle portion 3212. This application does not limit this, and those skilled in the art may make choices based on actual circumstances.

[0101] In some embodiments, as Figure 7 and Figure 8 As shown, the second member 322 is provided with a limiting portion 3223, and the first member 321 is provided with a limiting hole 3215. The limiting portion 3223 is movably inserted into the limiting hole 3215. The hole wall of the limiting hole 3215 is configured to stop the limiting portion 3223 when the first member 321 rotates relative to the second member 322, thereby restricting the rotation range of the first member 321 relative to the second member 322.

[0102] By cooperating with the limiting member 33 and the limiting hole 3215, the rotation range of the second component 322 relative to the first component 321 can be limited, thereby reducing the risk of damage to the second toggle part 3222 or the toggle switch 31 due to excessive rotation of the second component 322 relative to the first component 321, thereby extending the service life of the on-off assembly 30.

[0103] In other embodiments, the limiting portion 3223 and the limiting hole 3215 can also be set in reverse. For example, the second component 322 is provided with a limiting hole 3215, and the first component 321 is provided with a limiting portion 3223. This application does not limit this, and those skilled in the art can choose according to actual conditions.

[0104] In some embodiments, as Figure 7 and Figure 8As shown, the knob 32 further includes a damping member 323, which is mounted between the first member 321 and the second member 322, with the opposite ends of the damping member 323 respectively contacting the first member 321 and the second member 322. When the knob 32 is in the first state, the first member 321 and the second member 322 can rotate synchronously under the action of the damping member 323.

[0105] It can be understood that when the first component 321 is not stopped by the limiting component 33 , the first component 321 and the second component 322 can rotate synchronously under the action of the damping component 323 .

[0106] When the first component 321 is stopped by the limiter 33, the user needs to apply a greater force to overcome the damping force to enable the second component 322 to rotate relative to the first component 321, which helps reduce the risk of the user accidentally shutting down the communication between the relay 10 and the control module 20.

[0107] In some embodiments, the damping member 323 includes a first elastic member 343 and a fixed block 3232, one end of the first elastic member 343 abuts against the second member 322, and the other end is connected to the fixed block 3232, and the fixed block 3232 is configured to abut against the first member 321 under the action of the first elastic member 343.

[0108] The damping member 323 is in the form of a combination of a first elastic member 343 and a fixing block 3232, which can reduce the risk of the first member 321 and the second member 322 being unable to switch between the first state and the second state due to assembly errors between the first member 321 and the second member 322.

[0109] For example, assuming that an assembly error exists between the first and second components 322 resulting in excessive force between the two, the user will not be able to rotate the second component 322 relative to the first component 321 when the first component 321 is stopped.

[0110] Alternatively, if the force between the first and second members 322 is too small due to an assembly error between the first and second members 322, the user cannot achieve synchronous rotation of the first and second members 322 when the first member 321 is not stopped.

[0111] In some embodiments, the first component 321 and the second component 322 can achieve synchronous rotation through static friction between the two, such as increasing the locking force of fasteners (specifically screws, screws and other threaded parts) when connecting the first component 321 and the second component 322.

[0112] In some embodiments, the damping member 323 includes a fixing block 3232 made of rubber. The first component 321 and the second component 322 can rotate synchronously due to the elastic potential energy of the fixing block 3232 .

[0113] In some embodiments, the damping member 323 further includes a rolling member (not shown), which is disposed between the fixed block 3232 and the first member 321 and is rollingly connected to the fixed block 3232 and the first member 321. The provision of the rolling member can convert the sliding friction between the fixed block 3232 and the first member 321 into rolling friction, thereby making the relative rotation of the first member 321 and the second member 322 smoother and reducing the risk of jamming or blocking.

[0114] In some embodiments, the knob 32 further includes a reset member 34 mounted on the stop member 33. The reset member 34 is configured to apply a force to the first active wall 3213 or the second active wall 3214 to force the first toggle portion 3212 to return to its initial position. The initial position is when the mechanical switch 11 is positioned between the first active wall 3213 and the second active wall 3214 and the first active wall 3213 or the second active wall 3214 is not acting on the mechanical switch 11.

[0115] It is understandable that when the user drives the knob 32 to move, the reset member 34 can restore the first member 321 to its original position, which helps to reduce the user's operating actions. The following two abnormal situations of the relay 10 are described as examples:

[0116] For example, when the relay 10 is stuck rather than experiencing a communication anomaly such as a software or program failure, the user applies force to synchronize the rotation of the knob 32, the first member 321, and the second member 322. At this point, one of the first action wall 3213 or the second action wall 3214 of the first toggle portion 3212 acts on the mechanical switch 11, causing it to move and thereby releasing the stuck contacts of the relay 10.

[0117] When the user cancels the applied force, the reset member 34 drives the first toggle portion 3212 to return to the initial position, that is, the knob 32 returns to the initial position, to wait for the next time when the relay 10 is stuck and then toggle the mechanical switch 11.

[0118] For example, after disconnecting the communication connection between control module 20 and relay 10, when manually adjusting relay 10, the user applies force to the knob 32, causing the first member 321 and the second member 322 to rotate synchronously. At this point, one of the first action wall 3213 or the second action wall 3214 in the first toggle portion 3212 acts on the mechanical switch 11, driving the mechanical switch 11 to move, thereby electrically connecting relay 10 to the corresponding input source. When the user removes the applied force, the reset member 34 drives the first toggle portion 3212 back to its initial position, thereby returning the knob 32 to its initial position.

[0119] The first rotation direction is defined as the direction in which the knob is rotated clockwise, and the second rotation direction is defined as the direction in which the knob is rotated counterclockwise.

[0120] In some embodiments, as Figure 6 and Figure 10 As shown, the reset member 34 includes a first connecting section 341, a second connecting section 342, and a second elastic member 3231. The first connecting section 341 and the second connecting section 342 are mounted on the limiting member 33 in an "X" shape, and the first connecting section 341 and the second connecting section 342 rotate relative to each other. The second elastic member 3231 is connected to the same end of the first connecting section 341 and the second connecting section 342.

[0121] The limiting member 33 is provided with a first protrusion 333 and a second protrusion 334, the first connecting section 341 is provided with a first clamping portion 344, and the second connecting section 342 is provided with a second clamping portion 345. The first clamping portion 344 abuts against the first protrusion 333 to constrain the position of the first connecting section 341, and the second clamping portion 345 abuts against the second protrusion 334 to constrain the position of the second connecting section 342.

[0122] As can be understood, when the first member 321 rotates in the first rotational direction, the first driving portion 3212 pushes the first connecting section 341 to rotate, and the second engaging portion 345 stops the second connecting section 342 from rotating in the first rotational direction. This means that the first connecting section 341 and the second connecting section 342 rotate relative to each other. At this time, the second elastic member 3231 deforms elastically and accumulates elastic potential energy.

[0123] When the user releases the force applied to the knob 32, the second elastic member 3231 releases its elastic potential energy, and the second elastic member 3231 drives the first connecting section 341 and the second connecting section 342 to rotate relative to each other in opposite directions. At this time, the first connecting section 341 drives the first toggle portion 3212 to move to the initial position.

[0124] When the first member 321 rotates in the second rotational direction, the first driving portion 3212 pushes the second connecting section 342 to rotate, and the first engaging portion 344 stops the first connecting section 341 from rotating in the second rotational direction. In other words, the first connecting section 341 and the second connecting section 342 rotate relative to each other. At this time, the second elastic member 3231 undergoes elastic deformation and accumulates elastic potential energy.

[0125] When the user releases the force applied to the knob 32, the second elastic member 3231 releases its elastic potential energy, and the second elastic member 3231 drives the first connecting section 341 and the second connecting section 342 to rotate relative to each other in opposite directions. At this time, the second connecting section 342 drives the first toggle portion 3212 to move to the initial position.

[0126] In other embodiments, the reset member 34 can also be directly formed as a torsion spring (not shown). The torsion spring has a first torsion arm and a second torsion arm. The first torsion arm acts on the first toggle portion 3212, and the second torsion arm acts on the stop member 33. When the knob 32 rotates relative to the stop member 33, the first torsion arm and the second torsion arm move relative to each other. This application does not limit this, and those skilled in the art may select the spring based on their actual needs.

[0127] In some embodiments, as Figure 11 As shown, the first component 321 is provided with a positioning portion 3216 in a direction away from the second component 322 , and the limiting member 33 is provided with a positioning groove 335 on a side facing the first component 321 , and the positioning portion 3216 is rotatably inserted into the positioning groove 335 .

[0128] It is understandable that when installing the first component 321, the user only needs to insert the positioning portion 3216 in the first component 321 into the positioning groove 335 in the limiter 33 along the direction of the rotation axis O to achieve precise alignment of the first component 321 and the limiter 33.

[0129] Through the cooperation of the positioning portion 3216 and the positioning groove 335, not only can the relative rotation between the knob 32 and the limit member 33 be achieved, but also the installation efficiency of the knob 32 can be improved, and the risk of the first toggle portion 3212 and the mechanical switch 11 being damaged by conflict due to the offset of the first component 321 and the limit member 33 along the direction of the rotation axis O can be reduced, which is beneficial to protecting the relay 10 and the knob 32.

[0130] In some embodiments, as Figure 4 As shown, the first member 321 and the second member 322 are coaxially arranged. By coaxially arranging the first member 321 and the second member 322, the volume of the knob 32 can be reduced, thereby reducing the space occupied by the entire on-off assembly 30. Of course, in other embodiments, the first member 321 and the second member 322 can also be coaxial. This is not limited in this application, and those skilled in the art can make choices based on actual circumstances.

[0131] For example, when the relay 10 in the power distribution device 100 is stuck or a software fault is misjudged due to a control program fault, the operation flow of the power distribution device 100 is as follows:

[0132] The knob 32 is rotated to rotate the second member 322 relative to the first member 321 . The second toggle portion 3222 acts on the toggle switch 31 and cuts off the communication connection between the relay 10 and the control module 20 .

[0133] After the communication connection between the relay 10 and the control module 20 is severed, the knob 32 is rotated again to synchronize the second member 322 with the first member 321. The first toggle portion 3212 acts on the mechanical switch 11, controlling the relay 10 to be electrically connected to one of the different input power sources, thereby switching between the mains power side and the other input power source.

[0134] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
