Abstract
Description
Technical Field
[0001] The present application relates to the field of relay technology, and in particular to a relay assembly, power distribution equipment, and energy storage and power distribution coordination device. Background Art
[0002] Usually, the open or closed state of the two relays is manually controlled to prevent the relays from being in the open state at the same time to avoid circuit abnormalities. In the related art, when two relays are placed side by side, the structure is limited and it is not convenient for manual control. Utility Model Content
[0003] In view of this, the present application provides a relay assembly, power distribution equipment and energy storage and distribution coordination device, which can achieve mechanical interlocking of a first relay and a second relay arranged side by side.
[0004] One embodiment of the present application provides a relay assembly. The relay assembly includes a first relay, a second relay, and a limiting member. The first relay has a first swing switch. The second relay has a second swing switch. The second relay and the first relay are positioned side by side. When the second swing switch and the first swing switch swing in the same direction, the second relay and the first relay operate in the same state. The limiting member includes a stop structure. The stop structure cooperates with the first and second swing switches to limit the movement of the first and / or second swing switches and is configured to prevent the first swing switch from being in a closed position and the second swing switch from being in a closed position at the same time.
[0005] In the above embodiment, when the first relay and the second relay are arranged side by side, the swinging movement of the first swing switch and the second swing switch is constrained by the stop structure of the limiting member, limiting the movement of the second swing switch when the first swing switch is in the closed position, and limiting the movement of the first swing switch when the second swing switch is in the closed position, thereby achieving mechanical interlocking of the first relay and the second relay.
[0006] In some embodiments of the present application, the stop structure includes a limiter. The limiter is configured to be able to withstand external force to move from an initial position to a first position or a second position. When the limiter is in the initial position, the limiter limits the movement of the first swing switch and the second swing switch to prevent the first swing switch and the second swing switch from switching to the closed position at the same time. When the limiter moves to the first position, the limiter limits the movement of the second swing switch to prevent the second swing switch from being in the closed position. When the limiter moves to the second position, the limiter limits the movement of the first swing switch to prevent the first swing switch from being in the closed position.
[0007] In the above embodiment, the limit member can simultaneously limit the movement of the first swing switch and the second swing switch when it is in the initial position, and when the limit member moves to the first position or the second position, it changes its position relative to the first relay and the second relay to limit the movement of one of the first swing switch and the second swing switch, respectively. As a result, the limit member can simultaneously limit the movement of both the first swing switch and the second swing switch or only one of them by moving to different positions, thereby achieving mechanical interlocking of the first relay and the second relay.
[0008] In some embodiments of the present application, the stop structure further includes a first stop member and a second stop member. Both the first stop member and the second stop member cooperate with the limiting member to limit the position. The first stop member is configured to be moved by the first swing switch and drive the limiting member to move from an initial position to a first position, thereby stopping the movement of the second stop member and limiting the movement of the second swing switch. Alternatively, the second stop member is configured to be moved by the second swing switch and drive the limiting member to move from an initial position to a second position, thereby stopping the movement of the first stop member and limiting the movement of the first swing switch.
[0009] In the above embodiment, the first swing switch cooperates with the limiting member via the first stop. When the first swing switch is switched to the closed position, the limiting member can be pushed to the first position by pushing the first stop, thereby limiting the movement of the second stop, thereby limiting the movement of the second swing switch. The second swing switch cooperates with the limiting member via the second stop. When the second swing switch is switched to the closed position, the limiting member can be pushed to the second position by pushing the second stop, thereby limiting the movement of the first stop, thereby limiting the movement of the first swing switch.
[0010] In some embodiments of the present application, when the limit member is in the initial position, under the action of the first swing switch and the second swing switch, the first stop member and the second stop member simultaneously have a tendency to drive the limit member to move in opposite directions, so that the limit member is maintained in the initial position, while stopping the movement of the first stop member and the second stop member and limiting the action of the first swing switch and the continued action of the second swing switch.
[0011] In the above embodiment, when the limiter is in the initial position and the first stopper and the second stopper simultaneously attempt to move the limiter, the limiter will remain in the initial position, and neither the first stopper nor the second stopper can drive the limiter to move to the first position or the second position. The first stopper and the second stopper interact with each other, causing the limiter to restrict the movement of both the first and second swing switches.
[0012] In some embodiments of the present application, the limiter comprises a first recess, a second recess, a first stop wall, and a second stop wall. When the limiter is in the first position, the first recess aligns with the first stop to allow the first stop to move and release the restriction on the operation of the first swing switch, and the second stop wall blocks the movement of the second stop to limit the operation of the second swing switch. When the limiter is in the second position, the second recess aligns with the second stop to allow the second stop to move and release the restriction on the operation of the second swing switch, and the first stop wall blocks the movement of the first stop to limit the operation of the first swing switch. When the limiter is in the initial position, the first recess aligns with the first stop, and the second recess aligns with the second stop. When the first stop enters the first recess under the action of the first swing switch, and the second stop enters the second recess under the action of the second swing switch, the limiter moves in opposite directions and is restricted, simultaneously blocking the movement of the first and second stops and restricting the operation of the first and second swing switches.
[0013] In the above embodiment, the position limiter is provided with a first recessed portion to allow for movement of the first stopper, and a first stop wall to constrain movement of the first stopper. The position limiter is provided with a second recessed portion to allow for movement of the second stopper, and a second stop wall to constrain movement of the second stopper. The position of the position limiter is adjusted so that when the first recessed portion and the first stopper align, the second stop wall and the second stopper align, and when the second recessed portion and the second stopper align, the first stop wall and the first stopper align. This allows one of the first and second swing switches to switch to the closed position while the other is restricted from switching to the closed position, thereby achieving mechanical interlocking of the first and second relays. When the position limiter moves to its initial position, the first stopper and the first recessed portion align simultaneously with the second stopper and the second recessed portion, allowing both the first and second stoppers to move. When the first stop member and the second stop member move simultaneously and the limit member has two opposite movement trends, the two opposite movement trends cancel each other out, so that the limit member is maintained in the initial position, thereby simultaneously limiting the movement of the first swing switch and the second swing switch to achieve mechanical interlocking of the first relay and the second relay.
[0014] In some embodiments of the present application, the first recessed portion is provided with a first inclined surface. The first stopper is configured to move along the first inclined surface to push the limiting member to move toward the first position. The second recessed portion is provided with a second inclined surface. The second stopper is configured to move along the second inclined surface to push the limiting member to move toward the second position.
[0015] In the above embodiment, when the first stopper moves, it abuts and pushes the first inclined surface, thereby pushing the limiter to the first position, thereby automatically switching the limiter to a position that restricts the movement of the second swing switch. When the second stopper moves, it abuts and pushes the second inclined surface, thereby pushing the limiter to the second position, thereby automatically switching the limiter to a position that restricts the movement of the first swing switch. Alternatively, the first and second stopper move simultaneously, causing the limiter to have opposite movement trends, thereby stopping at the initial position, thereby simultaneously restricting the movement of the first and second swing switches.
[0016] In some embodiments of the present application, the limiting member further includes an elastic member, the elastic member is connected to the limiting member, and the elastic member is configured to apply an elastic force to the limiting member to move it to an initial position.
[0017] In the above embodiment, by providing an elastic member, when the first swing switch and the second swing switch are both switched to the open position, the limit member is automatically reset to the initial position, so that the next time the first swing switch or the second swing switch is moved to the closed position, the operation can be performed directly without hindrance.
[0018] In some embodiments of the present application, the position limiting member further comprises a housing box. The position limiting member is movably disposed within the housing box. The first stop member and the second stop member are both disposed within the housing box. A portion of the first stop member and a portion of the second stop member are located within the housing box and engage with the position limiting member.
[0019] In the above embodiment, the limit member moves in the accommodating box, and the first stop member and the second stop member can enter the accommodating box and cooperate with the limit member to protect the movement of the limit member from interference from the external environment, thereby stably achieving mechanical interlocking of the first relay and the second relay.
[0020] In some embodiments of the present application, the container is provided with a first limiting hole and a second limiting hole. A first stopper extends through the first limiting hole to extend into the container and is movable along the wall of the first limiting hole to engage with the limiting hole. A second stopper extends through the second limiting hole to extend into the container and is movable along the wall of the second limiting hole to engage with the limiting hole.
[0021] In the above embodiment, the accommodating box is provided with a first limiting hole to allow the first stopper to enter the accommodating box and engage with the limiting member, and a second limiting hole is provided to allow the second stopper to enter the accommodating box and engage with the limiting member. Furthermore, the first stopper is constrained and limited by the hole wall of the first limiting hole, thereby guiding its movement, while the second stopper is constrained and limited by the hole wall of the second limiting hole, thereby guiding its movement. Thus, the first stopper moves stably under the drive of the first swing switch, and the second stopper moves stably under the drive of the second swing switch, thereby stably achieving mechanical interlocking of the first relay and the second relay.
[0022] In some embodiments of the present application, the limiting member is provided with a guide rail, and the limiting member is configured to slide along the guide rail to different positions to limit the first swing switch action and / or the second swing switch action.
[0023] In the above embodiment, by providing a guide rail, the limit member is accurately moved to different positions, thereby accurately limiting the action of the first swing switch and / or the second swing switch, and stably achieving mechanical interlocking of the first relay and the second relay.
[0024] In some embodiments of the present application, the relay assembly further includes a first transmission member and a second transmission member. The first transmission member is configured to cooperate with the first swing switch and to operate in conjunction with the first swing switch. The second transmission member is configured to cooperate with the second swing switch and to operate in conjunction with the second swing switch. A stop structure cooperates with the first and second transmission members to limit the movement of the first and / or second transmission members to prevent the first and second swing switches from being in the closed position at the same time.
[0025] In the above embodiment, the first transmission member and the first swing switch are configured to operate in conjunction with each other, and the second transmission member and the second swing switch are configured to operate in conjunction with each other, so that the limit member indirectly limits the movement of the first and second swing switches through the first and second transmission members. The position and structure of the limit member are not limited to the location of the first and second swing switches, so that the limit member can limit the movement of the first and second transmission members, respectively, thereby achieving mechanical interlocking between the first and second relays.
[0026] In some embodiments of the present application, the direction of force applied by the first transmission member to push the first stop member is parallel to the direction of movement of the first stop member. The contact surface between the first transmission member and the first stop member is perpendicular to the direction of movement of the first stop member. The direction of force applied by the second transmission member to push the second stop member is parallel to the direction of movement of the second stop member. The contact surface between the second transmission member and the second stop member is perpendicular to the direction of movement of the second stop member.
[0027] In the above embodiment, the contact surface between the first transmission member and the first stop member is disposed perpendicularly to reduce the loss of the mutual force between the first transmission member and the first stop member in a direction other than the movement of the first stop member, thereby facilitating the stability of the first swing switch actuating the first stop member and the stability of the first swing switch actuating by the first stop member. The contact surface between the second transmission member and the second stop member is disposed perpendicularly to reduce the loss of the mutual force between the second transmission member and the second stop member in a direction other than the movement of the second stop member, thereby facilitating the stability of the second swing switch actuating the second stop member and the stability of the second swing switch actuating by the second stop member.
[0028] In some embodiments of the present application, the direction of force applied by the first transmission member to push the first stop member is perpendicular to the direction of movement of the first stop member. The contact surface between the first transmission member and the first stop member is tilted relative to the direction of movement of the first stop member. The direction of force applied by the second transmission member to push the second stop member is perpendicular to the direction of movement of the second stop member. The contact surface between the second transmission member and the second stop member is tilted relative to the direction of movement of the second stop member.
[0029] In the above embodiment, the contact surface between the first transmission member and the first stop member is tilted, which can change the direction of the force applied between the first transmission member and the first stop member, so that the space required for movement of the first transmission member and the space required for movement of the first stop member extend in different directions, thereby facilitating adjustment of the position of the first transmission member relative to the first stop member and improving space utilization. The contact surface between the second transmission member and the second stop member is tilted, which can change the direction of the force applied between the second transmission member and the second stop member, so that the space required for movement of the second transmission member and the space required for movement of the second stop member extend in different directions, thereby facilitating adjustment of the position of the second transmission member relative to the second stop member and improving space utilization.

A first relay and a second relay are configured to connect different circuits. The first relay is configured to control the on / off state of the circuit in which it resides. The second relay is configured to control the on / off state of the circuit in which it resides.
[0031] In the above embodiment, the power distribution equipment realizes mechanical interlocking of the first relay and the second relay by providing a relay assembly, thereby avoiding abnormality caused by simultaneous connection of the circuits where the first relay and the second relay are located.
[0032] One embodiment of the present application provides an energy storage and power distribution coordination device.

[0057] 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.
[0058] 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.
[0059] In the description of this application, it should be noted that the terms "inside" and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.
[0060] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0061] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.
[0062] Typically, manual control is used to open or close two relays to prevent them from being in the open state at the same time, thus avoiding circuit anomalies. In related art, placing two relays side by side creates structural limitations, making manual control inconvenient. The open state of a relay disconnects the circuit, while the closed state connects the circuit.
[0063] An embodiment of the present application provides a relay assembly. The relay assembly includes a first relay, a second relay, and a limiting member. The first relay has a first swing switch. The second relay has a second swing switch. The second relay and the first relay are placed side by side. When the second swing switch and the first swing switch swing to the same direction, the second relay and the first relay have the same working state. The limiting member includes a stop structure. The stop structure cooperates with the first swing switch and the second swing switch to limit the position, and is configured to limit the movement of the first swing switch and / or the second swing switch to avoid the first swing switch moving and the second swing switch being in the closed position at the same time. The relay closed position is the position in which the circuit is connected, and the relay open position is the position in which the circuit is disconnected, so that the circuit cannot be connected.
[0064] When the first relay and the second relay are arranged side by side, the swinging movement of the first swing switch and the second swing switch is constrained by the stop structure of the limiting member, limiting the movement of the second swing switch when the first swing switch is in the closed position, and limiting the movement of the first swing switch when the second swing switch is in the closed position, thereby realizing mechanical interlocking of the first relay and the second relay.
[0065] 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 can be combined with each other. Figures 5 to 8 The first relay and the second relay are omitted.
[0066] See also Figures 1 to 4 An embodiment of the present application provides a relay assembly 100 , a power distribution device 200 , and an energy storage and power distribution coordination device 300 .
[0067] See also Figure 1 In some embodiments, the energy storage and power distribution coordination device 300 includes an energy storage device 301 and a power distribution device 200. The energy storage device 301 and the power distribution device 200 are electrically connected.
[0068] See also Figure 1In some embodiments, energy storage device 301 has the functions of storing and discharging electricity, and can be used for home backup power, production unit backup power, outdoor work, outdoor entertainment, etc. Energy storage device 301 can be a small portable mobile power supply, household energy storage power supply, industrial and commercial energy storage power supply, or containerized energy storage power supply. Energy storage device 301 supplies power to power distribution device 200, which distributes the power supplied by energy storage device 301 to the load, which can be a home power grid or electrical devices.
[0069] See also Figure 1 and Figure 2 In some embodiments, the power distribution device 200 can control the connectivity of various circuits within a user's internal power grid. Users include individuals, households, and production units. As an example, the power distribution device 200 can control the power usage of the user's internal power grid. The power distribution device 200 is powered by the mains or via the energy storage device 301. The power distribution device 200 is responsible for distributing and utilizing the power supplied by the mains or the energy storage device 301.
[0070] See also Figures 2 to 4 In some embodiments, the power distribution device 200 includes a relay assembly 100. The energy storage device 301 is connected to the relay assembly 100. The relay assembly 100 controls whether the user's in-house power grid supplies power through the energy storage device 301.
[0071] See also Figure 2 In some embodiments, the power distribution device 200 further includes a distribution box 201. The relay assembly 100 is disposed in the distribution box 201 to protect the relay assembly 100.
[0072] See also Figure 3 and Figure 4 In some embodiments, a relay assembly 100 includes a first relay 10 and a second relay 20. The first relay 10 and the second relay 20 are configured to connect to different circuits. The first relay 10 is configured to control the on / off state of the circuit in which it resides. The second relay 20 is configured to control the on / off state of the circuit in which it resides. The relay assembly 100 can achieve mechanical interlocking between the first relay 10 and the second relay 20 to prevent anomalies caused by the simultaneous connection of the circuits in which the first relay 10 and the second relay 20 reside.
[0073] See also Figures 1 to 4 It is understandable that in some embodiments, one of the first relay 10 and the second relay 20 is electrically connected to the energy storage device 301, thereby avoiding abnormalities caused by simultaneous connection between the circuit where the energy storage device 301 is located and other circuits.
[0074] The power distribution equipment 200 is provided with a relay assembly 100 to achieve mechanical interlocking of the first relay 10 and the second relay 20, which allows only one relay to be in a closed state, thereby avoiding abnormalities caused by the circuits where the first relay 10 and the second relay 20 are located being connected at the same time.
[0075] In some embodiments, the first relay 10 and the second relay 20 are both connected to the user's internal power grid and are respectively connected to different input sources to control the conduction between the user's internal power grid and the different input sources, wherein the different input sources include the mains power grid, the energy storage device 301, the generator, etc.
[0076] See also Figure 3 and Figure 4 In some embodiments, the second relay 20 and the first relay 10 are placed side by side. The first relay 10 has a first swing switch 11. The second relay 20 has a second swing switch 21. When the second swing switch 21 and the first swing switch 11 swing to the same direction, the second relay 20 and the first relay 10 have the same operating state. As an exemplary example, the operating state of the first relay 10 includes an on state and an off state. When the first swing switch 11 swings to the closed position, the first relay 10 is in the on state, and when the first swing switch 11 swings to the open position, the first relay 10 is in the off state. The operating state of the second relay 20 includes an on state and an off state. When the second swing switch 21 swings to the closed position, the second relay 20 is in the on state, and when the second swing switch 21 swings to the open position, the second relay 20 is in the off state.
[0077] See also Figure 3 and Figure 4 In some embodiments, the first relay 10 and the second relay 20 are mounted side by side on a mounting surface S. Figure 3 As shown, the specific placement of the first relay 10 and the second relay 20 can be that the first swing switch 11 is located on the side facing the second relay 20 and the second swing switch 21 is located on the side facing the first relay 10, or the first swing switch 11 is located on the side away from the second relay 20 and the second swing switch 21 is located on the side facing the second relay 20, so that the first relay 10 and the second relay 20 are both placed on the side of the installation surface S. Figure 4 As shown, the specific placement form of the first relay 10 and the second relay 20 can also be that the first swing switch 11 and the second swing switch 21 are simultaneously located on the side facing the installation surface S or the side away from the installation surface S, so that the first relay 10 and the second relay 20 are both placed flat on the installation surface S.
[0078] See also Figure 3 and Figure 4In some embodiments, the relay assembly 100 further includes a limiting member 30. The limiting member 30 includes a stop structure 31. The stop structure 31 cooperates with the first swing switch 11 and the second swing switch 21 to limit the movement of the first swing switch 11 and / or the second swing switch 21, and is configured to prevent the first swing switch 11 from being in the closed position and the second swing switch 21 from being in the closed position at the same time.
[0079] When the first relay 10 and the second relay 20 are arranged side by side, the swinging movement of the first swing switch 11 and the second swing switch 21 is constrained by the stop structure 31 of the limiting member 30, limiting the movement of the second swing switch 21 when the first swing switch 11 is in the closed position, and limiting the movement of the first swing switch 11 when the second swing switch 21 is in the closed position, thereby realizing mechanical interlocking of the first relay 10 and the second relay 20.
[0080] See also Figure 3 and Figure 4 In some embodiments, the stop structure 31 includes a stopper 311. The stopper 311 is configured to receive an external force to move from an initial position (e.g. Figure 5 and Figure 6 ) moves to the first position (as shown) Figure 7 as shown) or the second position (as shown Figure 8 As shown). When the limiter 311 is in the initial position, the limiter 311 limits the movement of the first swing switch 11 and the second swing switch 21 to prevent the first swing switch 11 and the second swing switch 21 from switching to the closed position at the same time. When the limiter 311 moves to the first position, the limiter 311 limits the movement of the second swing switch 21 to prevent the second swing switch 21 from being in the closed position. When the limiter 311 moves to the second position, the limiter 311 limits the movement of the first swing switch 11 to prevent the first swing switch 11 from being in the closed position. Figure 5 and Figure 6 This is a diagram showing the limiting member 311 in its initial position. Figure 7 This is a diagram showing the limiting member 311 being in the first position. Figure 8 This is a schematic diagram of the limiting member 311 being in the second position.
[0081] The limit member 311 can simultaneously limit the movement of the first swing switch 11 and the second swing switch 21 when it is in the initial position. When the limit member 311 moves to the first position or the second position, it changes its position relative to the first relay 10 and the second relay 20 to limit the movement of one of the first swing switch 11 and the second swing switch 21 respectively. As a result, the limit member 311 moves to different positions to simultaneously limit the movement of both the first swing switch 11 and the second swing switch 21 or only one of them, thereby achieving mechanical interlocking of the first relay 10 and the second relay 20.
[0082] See also Figure 3 、 Figure 4 、 Figure 7 and Figure 8 It is understood that in some embodiments, if the first swing switch 11 is in the closed position and the second swing switch 21 is to be switched to the closed position, the first swing switch 11 needs to be switched to the open position to allow the limit member 311 to leave the first position, thereby allowing the second swing switch 21 to operate. If the second swing switch 21 is in the closed position and the first swing switch 11 is to be switched to the closed position, the second swing switch 21 needs to be switched to the open position to allow the limit member 311 to leave the second position, thereby allowing the first swing switch 11 to operate.
[0083] See also Figures 3 to 6 It can be understood that in some embodiments, the direction in which the limit member 311 moves is parallel to the distribution direction of the first relay 10 and the second relay 20, so that the limit member 311 can be moved to cooperate with the first swing switch 11 or the second swing switch 21 respectively.
[0084] See also Figure 3 and Figure 4 In some embodiments, the stop structure 31 further includes a first stopper 312 and a second stopper 313. The first stopper 312 and the second stopper 313 are both engaged with the limiting member 311. The first stopper 312 is configured to be moved by the first swing switch 11 and drive the limiting member 311 to move from the initial position to the first position (e.g., Figure 5 and Figure 7 As shown), the second stopper 313 is stopped from moving and the second swing switch 21 is restricted. Alternatively, the second stopper 313 is configured to be moved by the second swing switch 21 and drive the limiting member 311 to move from the initial position to the second position (as shown). Figure 6 and Figure 8 As shown), to stop the first stopper 312 from moving and limit the action of the first swing switch 11.
[0085] The first swing switch 11 cooperates with the limiter 311 via the first stopper 312. When the first swing switch 11 is switched to the closed position, the first stopper 312 can position the limiter 311 in the first position, thereby limiting the movement of the second stopper 313, thereby restricting the movement of the second swing switch 21. The second swing switch 21 cooperates with the limiter 311 via the second stopper 313. When the second swing switch 21 is switched to the closed position, the second stopper 313 is pushed to position the limiter 311 in the second position, thereby limiting the movement of the first stopper 312, thereby restricting the movement of the first swing switch 11.
[0086] See also Figures 3 to 6 In some embodiments, when the limit member 311 is located in the initial position, under the action of the first swing switch 11 and the second swing switch 21, the first stop member 312 and the second stop member 313 simultaneously have a tendency to drive the limit member 311 to move in opposite directions, so that the limit member 311 is maintained in the initial position, thereby simultaneously stopping the movement of the first stop member 312 and the second stop member 313, and limiting the action of the first swing switch 11 and the continued action of the second swing switch 21.
[0087] When the limit member 311 is in its initial position and the first stop member 312 and the second stop member 313 simultaneously attempt to move the limit member 311, the limit member 311 is subjected to opposing forces. These opposing forces cancel each other out, resulting in no force acting to move the limit member 311. The limit member 311 remains in its initial position, and neither the first stop member 312 nor the second stop member 313 can drive the limit member 311 to its first or second position. The interaction between the first stop member 312 and the second stop member 313 causes the limit member 311 to restrict the movement of both the first swing switch 11 and the second swing switch 21, preventing the first swing switch 11 and the second swing switch 21 from switching to their closed positions.
[0088] It will be appreciated that in some embodiments, the direction of movement of the first stopper 312 intersects with the direction of movement of the limiting member 311, so that when the limiting member 311 limits the movement of the first stopper 312, the first stopper 312 can also limit the movement of the limiting member 311. The direction of movement of the second stopper 313 intersects with the direction of movement of the limiting member 311, so that when the limiting member 311 limits the movement of the second stopper 313, the second stopper 313 can also limit the movement of the limiting member 311. Exemplarily, the directions of movement of the first stopper 312 and the second stopper 313 are both perpendicular to the direction of movement of the limiting member 311.
[0089] In other embodiments, the first stopper 312 and the second stopper 313 may not push the limiting member 311 , and the limiting member 311 is moved by being pushed by other structures or external forces.
[0090] See also Figure 3 and Figure 4 In some embodiments, the limiting member 311 is provided with a first recessed portion 3111, a second recessed portion 3112, a first stop wall 3113 and a second stop wall 3114. Figure 7As shown, when the limiting member 311 is in the first position, the first recessed portion 3111 and the first stop member 312 are aligned to allow the first stop member 312 to move to release the restriction on the action of the first swing switch 11, and the second stop wall 3114 stops the second stop member 313 from moving to restrict the action of the second swing switch 21. Figure 8 As shown, when the limit member 311 is in the second position, the second recess 3112 and the second stop member 313 are aligned to allow the second stop member 313 to move to release the restriction on the action of the second swing switch 21, and the first stop wall 3113 stops the first stop member 312 from moving to limit the action of the first swing switch 11.
[0091] The limiting member 311 is provided with a first recessed portion 3111 to avoid movement of the first stopper 312, and a first stopper wall 3113 to constrain movement of the first stopper 312. The limiting member 311 is provided with a second recessed portion 3112 to avoid movement of the second stopper 313, and a second stopper wall 3114 to constrain movement of the second stopper 313. By adjusting the position of the limit member 311, the second stop wall 3114 and the second stop member 313 are aligned when the first recess 3111 and the first stop member 312 are aligned, and the first stop wall 3113 and the first stop member 312 are aligned when the second recess 3112 and the second stop member 313 are aligned, so that one of the first swing switch 11 and the second swing switch 21 can be switched to the closed position while the other is restricted and cannot be switched to the closed position, thereby realizing mechanical interlocking of the first relay 10 and the second relay 20.
[0092] See also Figures 3 to 6 In some embodiments, the first stopper 312 is configured to push the limiting member 311 to move toward the first position when entering the first recessed portion 3111. The second stopper 313 is configured to push the limiting member 311 to move toward the second position when entering the second recessed portion 3112. Figure 7 and Figure 8 As shown, the direction in which the limiter 311 moves toward the first position is opposite to the direction in which it moves toward the second position. When the limiter 311 is in the initial position, the first recess 3111 and the first stopper 312 are aligned, and the second recess 3112 and the second stopper 313 are aligned. When the first stopper 312 enters the first recess 3111 under the action of the first swing switch 11, and the second stopper 313 enters the second recess 3112 under the action of the second swing switch 21, the limiter 311 moves in opposite directions and is restricted in its movement.
[0093] When the limiter 311 moves to its initial position, the first stopper 312 and the first recessed portion 3111 align with the second stopper 313 and the second recessed portion 3112, allowing both the first and second stopper 312, 313 to move. However, if one of the first and second stopper 312, 313, moves, causing the limiter 311 to change position, the movement of the other will be restricted. This allows the limiter 311 to automatically restrict the movement of the second swing switch 21 after the first swing switch 11 switches to the closed position, and vice versa. However, if both the first and second stopper 312, 313 move simultaneously, and the limiter 311 has two opposing motions, the two opposing motions cancel each other out, maintaining the limiter 311 in its initial position and thereby restricting the movement of both the first and second swing switches 11, 21.
[0094] See also Figures 3 to 6 In some embodiments, the first recessed portion 3111 is provided with a first inclined surface 3115. The first stopper 312 is configured to move along the first inclined surface 3115 to push the limiting member 311 to move toward the first position. The second recessed portion 3112 is provided with a second inclined surface 3116. The second stopper 313 is configured to move along the second inclined surface 3116 to push the limiting member 311 to move toward the second position.
[0095] When the first stopper 312 moves, it abuts and pushes the first inclined surface 3115, thereby pushing the limiter 311 to the first position, thereby automatically switching the limiter 311 to the position that restricts the movement of the second swing switch 21. When the second stopper 313 moves, it abuts and pushes the second inclined surface 3116, thereby pushing the limiter 311 to the second position, thereby automatically switching the limiter 311 to the position that restricts the movement of the first swing switch 11. Alternatively, the first stopper 312 and the second stopper 313 move simultaneously, causing the limiter 311 to have opposite movement trends, thereby stopping at the initial position, thereby simultaneously restricting the movement of the first swing switch 11 and the second swing switch 21.
[0096] It can be understood that in some embodiments, the first inclined surface 3115 is inclined relative to the direction of movement of the first stop member 312 and is inclined relative to the direction of movement of the limit member 311, and the second inclined surface 3116 is inclined relative to the direction of movement of the second stop member 313 and is inclined relative to the direction of movement of the limit member 311.
[0097] See also Figures 3 to 6In some embodiments, when the limit member 311 is in the initial position, the first stop member 312 is aligned with the first inclined surface 3115, and the second stop member 313 is aligned with the second inclined surface 3116, so that the relay assembly 100 can select which of the first stop member 312 and the second stop member 313 pushes the limit member 311 to move.
[0098] See also Figures 5 to 8 It can be understood that in some embodiments, when the first stop member 312 moves into the first recessed portion 3111 and the second stop member 313 moves into the second recessed portion 3112 at the same time, if the first stop member 312 and the second stop member 313 exert the same force on the limiting member 311, the limiting member 311 is maintained at the initial position and the movement of the first stop member 312 and the second stop member 313 is restricted at the same time; if the force exerted by the first stop member 312 is greater, the limiting member 311 moves to the first position and the first stop member 312 can continue to move; if the force exerted by the second stop member 313 is greater, the limiting member 311 moves to the second position and the second stop member 313 can continue to move.
[0099] See also Figure 5 and Figure 6 It can be understood that in some embodiments, the structure of the limiting member 311 is symmetrical front to back along the moving direction with its own midpoint in the moving direction as the boundary.
[0100] See also Figures 3 to 6 In some embodiments, the limiting member 30 further includes an elastic member 32. The elastic member 32 is connected to the limiting member 311. The elastic member 32 is configured to apply an elastic force to the limiting member 311 to move it to the initial position.
[0101] By providing the elastic member 32, when the first swing switch 11 and the second swing switch 21 are both switched to the on position, the limit member 311 is automatically reset to the initial position, so that the next time the first swing switch 11 or the second swing switch 21 is moved, the operation can be performed directly without hindrance.
[0102] In some embodiments, the elastic member 32 is a spring or a torsion spring. In other embodiments, the elastic member 32 can be a structure such as an elastic arm provided on the housing structure and capable of generating elastic deformation.
[0103] In some embodiments, the elastic member 32 is configured such that, when the first swing switch 11 is in the closed position, the elastic force applied by the elastic member 32 to the limit member 311 is transmitted to the first swing switch 11, preventing the first swing switch 11 from switching to the open position, so that the first relay 10 is stably in the open state; when the second swing switch 21 is in the closed position, the elastic force applied by the elastic member 32 to the limit member 311 is transmitted to the second swing switch 21, preventing the second swing switch 21 from switching to the open position, so that the second relay 20 is stably in the open state.
[0104] In some embodiments, two elastic members 32 are provided. One elastic member 32 is configured to apply an elastic force to the limiting member 311 to move from the first position to the initial position, and the other elastic member 32 is configured to apply an elastic force to the limiting member 311 to move from the second position to the initial position.
[0105] In some embodiments, the limiting member 30 further includes a housing 33. A limiting member 311 is movably disposed within the housing 33. A first stopper 312 and a second stopper 313 are both disposed within the housing 33. Portions of the first stopper 312 and a portion of the second stopper 313 are located within the housing 33 and engage with the limiting member 311 to limit the position.
[0106] The limit member 311 moves in the accommodating box 33, and the first stop member 312 and the second stop member 313 can enter the accommodating box 33 and cooperate with the limit member 311 to protect the movement of the limit member 311 from interference from the external environment, thereby stably realizing the mechanical interlocking of the first relay 10 and the second relay 20.
[0107] It is understood that in some embodiments, when the first swing switch 11 is actuated to move the first stopper 312, the portion of the first stopper 312 located outside the accommodating box 33 decreases, while the portion located inside the accommodating box 33 increases. When the second swing switch 21 is actuated to move the second stopper 313, the portion of the second stopper 313 located outside the accommodating box 33 decreases, while the portion located inside the accommodating box 33 increases.
[0108] It is understood that in some embodiments, the elastic member 32 is disposed in the accommodating box 33 to protect the elastic member 32 from interference from the external environment.
[0109] In some embodiments, the accommodating box 33 is provided with a first limiting hole 331 and a second limiting hole 332. The first stopper 312 extends through the first limiting hole 331 to extend into the accommodating box 33 and can move along the wall of the first limiting hole 331 to engage with the limiting member 311. The second stopper 313 extends through the second limiting hole 332 to extend into the accommodating box 33 and can move along the wall of the second limiting hole 332 to engage with the limiting member 311.
[0110] The accommodating box 33 is provided with a first limiting hole 331 to allow the first stopper 312 to enter the accommodating box 33 and engage with the limiting member 311. A second limiting hole 332 is provided to allow the second stopper 313 to enter the accommodating box 33 and engage with the limiting member 311. Furthermore, the first limiting hole 331 restricts the position of the first stopper 312, thereby guiding its movement. The second limiting hole 332 restricts the position of the second stopper 313, thereby guiding its movement. As a result, the first stopper 312 moves stably under the influence of the first swing switch 11, and the second stopper 313 moves stably under the influence of the second swing switch 21, thereby stably achieving mechanical interlocking between the first relay 10 and the second relay 20.
[0111] See also Figures 5 to 8 In some embodiments, the first stopper 312 is provided with a first guide arm 3121 and a first protrusion 3122. The first guide arm 3121 is attached to the side wall of the limiter 311 to guide the movement of the first stopper 312. The first protrusion 3122 is protruded from the side of the first guide arm 3121 facing the limiter 311. The first protrusion 3122 is configured to enter the first recess 3111 and move along the first inclined surface 3115 to push the limiter 311 to move toward the first position. When the limiter 311 is in the second position, the first stop wall 3113 stops the first protrusion 3122 to limit the movement of the first stopper 312, thereby limiting the operation of the first swing switch 11.
[0112] In some embodiments, the second stopper 313 is provided with a second guide arm 3131 and a second protrusion 3132. The second guide arm 3131 abuts against the sidewall of the stopper 311 to guide the movement of the second stopper 313. The second protrusion 3132 is provided on the side of the second guide arm 3131 facing the stopper 311. The second protrusion 3132 is configured to enter the second recess 3112 and move along the second inclined surface 3116 to push the stopper 311 toward the second position. When the stopper 311 is in the first position, the second stop wall 3114 blocks the second protrusion 3132, thereby limiting the movement of the second stopper 313 and thereby limiting the operation of the second swing switch 21.
[0113] In some embodiments, the limiting member 30 is provided with a guide rail 333. The limiting member 311 is configured to slide along the guide rail 333 to different positions to limit the movement of the first swing switch 11 and / or the second swing switch 21.
[0114] By providing the guide rail 333 , the limiter 311 can be accurately moved to different positions, thereby accurately limiting the action of the first swing switch 11 and / or the second swing switch 21 , thereby stably achieving mechanical interlocking of the first relay 10 and the second relay 20 .
[0115] In some embodiments, the guide rail 333 is provided on the inner wall of the accommodating box 33. For example, the guide rail 333 can be formed in a convex shape or in a concave shape.
[0116] See also Figure 3 and Figure 4 In some embodiments, the relay assembly 100 further includes a first transmission member 40 and a second transmission member 50. The first transmission member 40 is configured to cooperate with the first swing switch 11 and to operate in conjunction with the first swing switch 11. The second transmission member 50 is configured to cooperate with the second swing switch 21 and to operate in conjunction with the second swing switch 21. The stop structure 31 is engaged with the first transmission member 40 and the second transmission member 50 and is configured to limit the movement of the first transmission member 40 and / or the second transmission member 50 to prevent the first swing switch 11 and the second swing switch 21 from being in the closed position at the same time.
[0117] The first transmission member 40 and the first swing switch 11 are configured to operate in conjunction with each other, and the second transmission member 50 and the second swing switch 21 are configured to operate in conjunction with each other, so that the limit member 311 indirectly limits the movement of the first and second swing switches 11, 21 through the first and second transmission members 40, 50. The position and structure of the limit member 311 are not limited to the positions of the first and second swing switches 11, 21, so that the limit member 311 can limit the movement of the first and second transmission members 40, 50, respectively, thereby achieving mechanical interlocking between the first relay 10 and the second relay 20.
[0118] In some embodiments, the first transmission member 40 is rotatably mounted on the first relay 10 , and the second transmission member 50 is rotatably mounted on the second relay 20 .
[0119] In some embodiments, the first transmission member 40 and the first stop member 312 are aligned and cooperate with each other. When the first swing switch 11 is actuated, the first transmission member 40 actuates synchronously and pushes the first stop member 312 to move. The limit member 311 stops the movement of the first stop member 312 to restrict the movement of the first transmission member 40, thereby restricting the movement of the first swing switch 11. The second transmission member 50 and the second stop member 313 are aligned and cooperate with each other. When the second swing switch 21 is actuated, the second transmission member 50 actuates synchronously and pushes the second stop member 313 to move. The limit member 311 stops the movement of the second stop member 313 to restrict the movement of the second transmission member 50, thereby restricting the movement of the second swing switch 21.
[0120] See also Figure 3In some embodiments, when the first relay 10 and the second relay 20 are both placed sideways on the mounting surface S, the direction of force applied by the first transmission member 40 to the first stopper 312 is parallel to the direction of movement of the first stopper 312, and the direction of force applied by the second transmission member 50 to the second stopper 313 is parallel to the direction of movement of the second stopper 313. The contact surface between the first transmission member 40 and the first stopper 312 is perpendicular to the direction of movement of the first stopper 312. The contact surface between the second transmission member 50 and the second stopper 313 is perpendicular to the direction of movement of the second stopper 313.
[0121] The contact surface between the first transmission member 40 and the first stopper 312 is disposed perpendicularly to reduce the loss of the mutual force between the first transmission member 40 and the first stopper 312 in directions other than the movement of the first stopper 312. This helps improve the stability of the movement of the first swing switch 11, which in turn drives the movement of the first stopper 312, and improves the stability of the movement of the first swing switch 11 restricted by the first stopper 312. The contact surface between the second transmission member 50 and the second stopper 313 is disposed perpendicularly to reduce the loss of the mutual force between the second transmission member 50 and the second stopper 313 in directions other than the movement of the second stopper 313. This helps improve the stability of the movement of the second swing switch 21, which in turn drives the movement of the second stopper 313, and improves the stability of the movement of the second swing switch 21, which in turn in turn drives the movement of the second stopper 313.
[0122] See also Figure 4 In some embodiments, when the first relay 10 and the second relay 20 are both placed flat on the mounting surface S, the force applied by the first transmission member 40 to the first stopper 312 is perpendicular to the direction of movement of the first stopper 312, and the force applied by the second transmission member 50 to the second stopper 313 is perpendicular to the direction of movement of the second stopper 313. The contact surface between the first transmission member 40 and the first stopper 312 is tilted relative to the direction of movement of the first stopper 312. The contact surface between the second transmission member 50 and the second stopper 313 is tilted relative to the direction of movement of the second stopper 313.
[0123] The inclined contact surface between the first transmission member 40 and the first stop 312 can change the direction of the force applied between the first transmission member 40 and the first stop 312, extending the space required for the movement of the first transmission member 40 and the space required for the movement of the first stop 312 in different directions. This facilitates adjustment of the position of the first transmission member 40 relative to the first stop 312, thereby improving space utilization. The inclined contact surface between the second transmission member 50 and the second stop 313 can change the direction of the force applied between the second transmission member 50 and the second stop 313, extending the space required for the movement of the second transmission member 50 and the space required for the movement of the second stop 313 in different directions. This facilitates adjustment of the position of the second transmission member 50 relative to the second stop 313, thereby improving space utilization.
[0124] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 7 In some embodiments, the first stopper 312 and the second stopper 313 may be omitted. The first transmission member 40 and the second transmission member 50 directly cooperate with the limiter 311. When the limiter 311 is in the first position, the first recessed portion 3111 aligns with the first transmission member 40 to allow the first transmission member 40 to move and release the restriction on the operation of the first swing switch 11, and the second stopper wall 3114 stops the second transmission member 50 from moving and restricting the operation of the second swing switch 21. When the limiter 311 is in the second position, the second recessed portion 3112 aligns with the second transmission member 50 to allow the second transmission member 50 to move and release the restriction on the operation of the second swing switch 21, and the first stopper wall 3113 stops the first transmission member 40 from moving and restricting the operation of the first swing switch 11.
[0125] In some embodiments, the first transmission member 40 is configured to push the limit member 311 toward the first position when entering the first recess 3111. The second transmission member 50 is configured to push the limit member 311 toward the second position when entering the second recess 3112. When the limit member 311 is in its initial position, and when the first transmission member 40 enters the first recess 3111 under the action of the first swing switch 11, and the second transmission member 50 enters the second recess 3112 under the action of the second swing switch 21, the limit member 311 moves in opposite directions and is restricted in its movement.
[0126] It is understood that in some embodiments, the first transmission member 40 is configured to move along the first inclined surface 3115 to push the limiting member 311 to move toward the first position, and the second transmission member 50 is configured to move along the second inclined surface 3116 to push the limiting member 311 to move toward the second position.
[0127] See also Figures 3 to 6In some embodiments, the mechanical interlocking principle of the relay assembly 100 is as follows:
[0128] The first swing switch 11 and the second swing switch 21 are both in the open position, and the limiting member 311 is in the initial position under the action of the elastic member 32 .
[0129] like Figure 7 As shown, when the first swing switch 11 is switched to the closed position, the first transmission member 40 actuates and pushes the first stopper 312 to move. The first stopper 312 enters the first recess 3111 and moves along the first inclined surface 3115, pushing the limit member 311 to the first position. The second stopper wall 3114 of the limit member 311 then stops the second stopper 313, restricting the movement of the second transmission member 50 and thus the movement of the second swing switch 21, thus achieving mechanical interlocking of the first relay 10 and the second relay 20.
[0130] like Figure 8 As shown, when the second swing switch 21 is switched to the closed position, the second transmission member 50 actuates and pushes the second stopper 313 to move. The second stopper 313 enters the second recess 3112 and moves along the second inclined surface 3116, pushing the limit member 311 to the second position. The first stopper wall 3113 of the limit member 311 then stops the first stopper 312, restricting the movement of the first transmission member 40 and thus the movement of the first swing switch 11, thus achieving mechanical interlocking of the first relay 10 and the second relay 20.
[0131] If the first swing switch 11 and the second swing switch 21 attempt to switch to the closed position simultaneously, the first transmission member 40 and the second transmission member 50 move simultaneously, pushing the first stopper 312 and the second stopper 313. The first stopper 312 enters the first recess 3111 and moves along the first inclined surface 3115 to attempt to move the limiter 311. The second stopper 313 enters the second recess 3112 and moves along the second inclined surface 3116 to move the limiter 311. The limiter 311 moves in opposite directions and remains in its initial position, preventing the first stopper 312 and the second stopper 313 from moving further. This restricts the movement of the first transmission member 40 and the second transmission member 50, and thus the movement of the first swing switch 11 and the second swing switch 21, thereby achieving mechanical interlocking of the first relay 10 and the second relay 20.
[0132] 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.
