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] Two relays can be interlocked through a mechanical interlocking structure to prevent the relays from being in the on state at the same time, thereby avoiding circuit abnormalities. In the related art, when two relays are placed opposite each other, the structure is limited and it is not convenient to set up a mechanical interlocking structure. Utility Model Content
[0003] In view of this, the present application provides a relay assembly, power distribution equipment and energy storage and power distribution coordination device, which can achieve mechanical interlocking of a first relay and a second relay that are relatively arranged.
[0004] One embodiment of the present application provides a relay assembly, comprising a first relay, a first transmission member, a second relay, and the second transmission member. The first relay has a first swing switch. The first transmission member is configured to cooperate with the first swing switch and operate in conjunction with the first swing switch. The second relay is positioned opposite the first relay. The second relay has a second swing switch. When the second swing switch and the first swing switch swing in opposite directions, the second relay and the first relay have the same operating state.
[0005] The second transmission member is configured to cooperate with the second swing switch and operate in conjunction with the second swing switch. The first transmission member and the second transmission member are configured to limit each other and restrict the operation of the first swing switch and / or the second swing switch to prevent the first swing switch and the second swing switch from being in the closed position at the same time.
[0006] In the above embodiment, when the first and second relays are positioned relative to each other, the first transmission member and the first swing switch are provided to operate in conjunction with each other, and the second transmission member and the second swing switch are provided to operate in conjunction with each other. This allows the movement of the first and second swing switches to be limited by the mutually restricted positions of the first and second transmission members. The mutually restricted structure of the first and second transmission members is not limited to the positions of the first and second swing switches, thereby facilitating positional limits on the movement of the first and second swing switches, thereby achieving mechanical interlocking between the first and second relays.
[0007] In some embodiments of the present application, a limit region is defined between the first relay and the second relay. When the first swing switch is in the closed position, at least a portion of the first transmission member is located in the limit region. When the second swing switch is in the closed position, at least a portion of the second transmission member is located in the limit region. The first and second transmission members are configured to form a mutual abutting force to limit further movement of the first and / or second transmission members and prevent the first and / or second swing switches from continuing to swing to the closed position.
[0008] In the above embodiment, when the first swing switch and the second swing switch attempt to be simultaneously in the closed position, the first transmission member and the second transmission member attempt to simultaneously remain in the limit zone. However, the mutual force between the first transmission member and the second transmission member forces at least one of the first transmission member and the second transmission member to leave the limit zone, preventing at least one of the first swing switch and the second swing switch from being in the closed position, thereby achieving mechanical interlocking of the first relay and the second relay.
[0009] In some embodiments of the present application, when the first transmission member is first located in the limiting region, the first transmission member is configured to prevent the second transmission member from further entering the limiting region, thereby preventing the second swing switch from switching to the closed position. When the second transmission member is first located in the limiting region, the second transmission member is configured to prevent the first transmission member from further entering the limiting region, thereby preventing the first swing switch from switching to the closed position.
[0010] In the above embodiment, when one of the first swing switch and the second swing switch is first in the closed position, the corresponding one of the first transmission member and the second transmission member is first located in the limit area, thereby stopping the other of the first transmission member and the second transmission member from continuing to enter the limit area, thereby restricting the corresponding other of the first swing switch and the second swing switch from also switching to the closed position, thereby realizing mechanical interlocking of the first relay and the second relay.
[0011] In some embodiments of the present application, when the first transmission member is first located in the limiting region, the second transmission member is configured to enter the limiting region and push the first transmission member out of the limiting region, thereby switching the first swing switch to the open position and the second swing switch to the closed position. When the second transmission member is first located in the limiting region, the first transmission member pushes the second transmission member out of the limiting region, thereby switching the second swing switch to the open position and the first swing switch to the closed position.
[0012] In the above embodiment, when one of the first and second swing switches is first in the closed position, the corresponding one of the first and second transmission members is first located in the restricted area. At this time, when the other of the first and second swing switches switches to the closed position, the corresponding one of the first and second transmission members moves toward the restricted area, first pushing the one of the first and second transmission members originally in the restricted area out of the restricted area, and then driving the one of the first and second swing switches that is linked to it to switch to the open position. The other of the first and second transmission members that enters the restricted area later then remains in the restricted area, and the other of the first and second swing switches that is linked to it smoothly switches to the closed position. Therefore, when one of the first and second swing switches is first in the closed position and the other switches to the closed position later, the one that was originally in the closed position is forced to switch to the open position, thereby achieving mechanical interlocking of the first and second relays.
[0013] In some embodiments of the present application, when the first transmission member and the second transmission member enter the limit area at the same time, the first transmission member and the second transmission member are configured to be able to press against each other to limit the first transmission member and the second transmission member from continuing to move and prevent the first swing switch and the second swing switch from continuing to swing to the closed position.
[0014] In the above embodiment, when the first transmission member and the second transmission member both move toward the limit area, the first transmission member and the second transmission member stop each other and prevent each other from continuing to move, so that the first transmission member and the second transmission member cannot move into place, so that the first swing switch and the second swing switch cannot be switched to the closed position, thereby realizing mechanical interlocking of the first relay and the second relay.
[0015] In some embodiments of the present application, the first transmission member is provided with a first limiter. The first limiter protrudes perpendicularly to the swing direction of the first transmission member. The second transmission member is provided with a second limiter. The second limiter protrudes perpendicularly to the swing direction of the second transmission member. The first limiter and the second limiter are configured to form a mutual abutting force to limit the movement of the first swing switch and / or the second swing switch and prevent the first and second swing switches from being in the closed position at the same time.
[0016] In the above embodiment, the direction in which the first limiting portion protrudes is perpendicular to the direction in which the first transmission member moves, so that the side of the first limiting portion facing the direction in which the first transmission member moves extends in the non-moving direction, thereby facilitating an increase in the area of the first transmission member for mating with the second transmission member. The direction in which the second limiting portion protrudes is perpendicular to the direction in which the second transmission member moves, so that the side of the second limiting portion facing the direction in which the second transmission member moves extends in the non-moving direction, thereby facilitating an increase in the area of the second transmission member for mating with the first transmission member. The abutment between the first limiting portion and the second limiting portion facilitates improving the stability of the mutual mating between the first transmission member and the second transmission member, thereby improving the stability of the mechanical interlocking of the first relay and the second relay.
[0017] In some embodiments of the present application, the relay assembly further includes a slider. The slider is slidably disposed between the first transmission member and the second transmission member. The first transmission member and the second transmission member are configured to mutually limit the movement of the first swing switch and / or the second swing switch by pushing the slider, thereby preventing the first swing switch and the second swing switch from being in the closed position at the same time.
[0018] In the above embodiment, by setting a slider, the first transmission member and the second transmission member indirectly cooperate to limit by pushing the slider, so that the setting positions of the first transmission member and the second transmission member are more diverse, which is conducive to enabling the relatively set first relay and the second relay to adjust the specific setting positions according to actual needs.
[0019] In some embodiments of the present application, the slider includes a first mating portion and a second mating portion. The first mating portion protrudes perpendicularly to the swinging direction of the first transmission member. The first transmission member is configured to abut the first mating portion and push the slider. The second mating portion protrudes perpendicularly to the swinging direction of the second transmission member. The second transmission member is configured to abut the second mating portion and push the slider.
[0020] In the above embodiment, the direction in which the first mating portion protrudes is perpendicular to the direction in which the first transmission member moves, so that the first mating portion extends toward a side surface of the first transmission member in the non-moving direction of the first transmission member, thereby facilitating an increase in the area of the portion of the slider used to mate with the first transmission member. The direction in which the second mating portion protrudes is perpendicular to the direction in which the second transmission member moves, so that the second mating portion extends toward a side surface of the second transmission member in the non-moving direction of the second transmission member, thereby facilitating an increase in the area of the portion of the slider used to mate with the second transmission member. The slider abuts against the first transmission member through the first mating portion, and abuts against the second transmission member through the second mating portion, which facilitates improving the stability of the mutual cooperation between the slider and the first transmission member, as well as between the slider and the second transmission member, thereby improving the stability of the mechanical interlocking of the first relay and the second relay.
[0021] In some embodiments of the present application, the relay assembly further includes a sliding seat and a stopper. The sliding seat is fixed relative to the first relay and the second relay. The slider slides on the sliding seat. The slider has a strip-shaped hole. The stopper passes through the strip-shaped hole and connects to the sliding seat. When the stopper abuts against the wall of the strip-shaped hole, the slider is restricted from sliding further.
[0022] In the above embodiment, the sliding seat is provided to slidably cooperate with the slider, thereby improving the stability of the slider's sliding and facilitating adjustment of the slider's position to match the positions of the first and second relays. A position-limiting member is connected to the sliding seat and passes through a strip-shaped hole in the slider. As the slider slides, the position of the position-limiting member relative to the slider is constrained by the strip-shaped hole, thereby restricting the slider's sliding range relative to the sliding seat, ensuring a stable fit between the slider and the sliding seat and improving the slider's sliding stability.
[0023] In some embodiments of the present application, the relay assembly further includes a sliding seat and a rolling element. The sliding seat is fixed relative to the first relay and the second relay. The slider slides on the sliding seat. The rolling element is disposed between the sliding seat and the slider. The rolling element and the slider engage in rolling engagement. The rolling element and the sliding seat engage in rolling engagement.
[0024] In the above embodiment, by providing a sliding engagement between the sliding seat and the slider, the stability of the slider's sliding is improved, and the slider's position can be easily adjusted to match the positions of the first and second relays. When the slider slides relative to the sliding seat, the slider and the rolling element roll together, and the sliding seat and the rolling element roll together, thereby reducing friction between the slider and the sliding seat, facilitating reduced interference with the limiting engagement between the first and second transmission elements, and thereby improving the stability of the mechanical interlocking of the first and second relays.
[0025] One embodiment of the present application provides a power distribution device. The power distribution device includes a relay assembly as described in any of the above embodiments. A first relay and a second relay are configured to connect to 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.
[0026] 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.
[0027] One embodiment of the present application provides an energy storage and power distribution coordination device. The energy storage and power distribution coordination device includes an energy storage device and a power distribution device as described in any of the above embodiments. One of a first relay and a second relay is electrically connected to the energy storage device.
[0028] In the above embodiment, the energy storage and power distribution coordination device realizes mechanical interlocking of the first relay and the second relay by setting a relay assembly, thereby avoiding abnormalities caused by the simultaneous connection of the circuit where the energy storage device is located and other circuits.

[0048] 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.
[0049] 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.
[0050] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0051] 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.
[0052] Two relays can be interlocked using a mechanical interlocking structure to prevent them from being in the on state at the same time, thus avoiding circuit anomalies. In related art, when two relays are placed opposite each other, the structure is limited, making it difficult to set up a mechanical interlocking structure. Unlike electrical interlocking, which prevents two relays from being in the on state at the same time through the coordination of relay contacts or circuit control, mechanical interlocking prevents two relays from being in the on state at the same time through the mechanical structure coordination relationship between mechanical components.
[0053] An embodiment of the present application provides a relay assembly, comprising a first relay, a first transmission member, a second relay, and a second transmission member. The first relay has a first swing switch. The first transmission member is configured to cooperate with the first swing switch and operate in conjunction with the first swing switch. The second relay is positioned opposite the first relay. The second relay has a second swing switch. When the second swing switch and the first swing switch swing to opposite directions, the second relay and the first relay have the same operating state. The second transmission member is configured to cooperate with the second swing switch and operate in conjunction with the second swing switch. The first transmission member and the second transmission member are configured to limit each other to restrict the operation of the first swing switch and / or the second swing switch, thereby preventing the first and second swing switches from being in the closed position at the same time. When the first or second swing switch is in the closed position, the circuit of the corresponding first or second relay is in the conducting state; when the first or second swing switch is in the open position, the circuit of the corresponding first or second relay is in the disconnected state.
[0054] When the first and second relays are positioned relative to each other, 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, thereby limiting the movement of the first and second swing switches by limiting the positions of the first and second transmission members. The structure in which the first and second transmission members mutually restrict each other is not limited to the positions of the first and second swing switches, thereby facilitating the limiting of the movement of the first and second swing switches, thereby achieving mechanical interlocking between the first and second relays.
[0055] 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.
[0056] See also Figures 1 to 3 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 .
[0057] 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.
[0058] In some embodiments, energy storage device 301 has the functions of storing and discharging electricity, and is 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.
[0059] In some embodiments, the power distribution device 200 can control the connectivity of various circuits in a user's on-premises power grid. Users include individuals, households, and production units. As an illustrative example, the power distribution device 200 can control the connection between the mains and the user's on-premises power grid to supply power to the user's on-premises power grid, or the connection between the energy storage device 301 and the user's on-premises power grid to supply power to the user's on-premises power grid.
[0060] See also Figure 1 and Figure 2 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.
[0061] 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.
[0062] See also Figures 1 to 3 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.
[0063] 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, and the other is electrically connected to other power sources. The other power sources can be mains power grid energy, photovoltaic energy, generators, etc., so as to avoid abnormalities caused by the circuit where the energy storage device 301 is located and other power supply circuits being connected at the same time.
[0064] The power distribution equipment 200 realizes mechanical interlocking of the first relay 10 and the second relay 20 by providing the relay assembly 100 , thereby avoiding abnormality caused by simultaneous connection of the circuits where the first relay 10 and the second relay 20 are located.
[0065] 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.
[0066] See also Figure 3 and Figure 5In some embodiments, the second relay 20 and the first relay 10 are positioned opposite each other. 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 opposite directions, 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. 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. When the second swing switch 21 swings to the open position, the second relay 20 is in the off state.
[0067] In some embodiments, the first relay 10 and the second relay 20 are mounted relative to each other on a mounting surface S. The specific placement of the first relay 10 and the second relay 20 can be that the first swing switch 11 and the second swing switch 21 are simultaneously located on the side facing the mounting surface S or the side facing away from the mounting surface S, so that the first relay 10 and the second relay 20 are both placed flat on the mounting surface S. When the first relay 10 and the second relay 20 are in the same working state, the first relay 10 and the second relay 20 are regarded as a whole, the first swing switch 11 swings toward one side of the whole, and the second swing switch 21 swings toward the other side of the whole. As an exemplary example, Figure 3 In the embodiment, the first swing switch 11 swings upward as shown in the figure, and the second swing switch 21 swings downward as shown in the figure, and the first relay 10 and the second relay 20 are both in the disconnected state.
[0068] In some embodiments, the relay assembly 100 further includes a first transmission member 30 and a second transmission member 40. The first transmission member 30 is configured to cooperate with the first swing switch 11 and operate in conjunction with the first swing switch 11. The second transmission member 40 is configured to cooperate with the second swing switch 21 and operate in conjunction with the second swing switch 21. The first transmission member 30 and the second transmission member 40 are configured to limit each other and restrict the operation of the first swing switch 11 and / or the second swing switch 21 to prevent the first swing switch 11 and the second swing switch 21 from being in the closed position at the same time.
[0069] When the first relay 10 and the second relay 20 are positioned relative to each other, the first transmission member 30 and the first swing switch 11 are provided to operate in conjunction with each other, and the second transmission member 40 and the second swing switch 21 are provided to operate in conjunction with each other. This allows the movement of the first and second swing switches 11, 21 to be limited by the mutually restricted positions of the first and second transmission members 30, 40. The mutually restricted structure of the first and second transmission members 30, 40 is not limited to the positions of the first and second swing switches 11, 21, thereby facilitating positional limits on the movement of the first and second swing switches 11, 21 and achieving mechanical interlocking between the first relay 10 and the second relay 20.
[0070] It can be understood that in some embodiments, the first transmission member 30 and the second transmission member 40 limit each other, limiting the movement of the first swing switch 11 to prevent the first swing switch 11 from being in the closed position; or limiting the movement of the second swing switch 21 to prevent the second swing switch 21 from being in the closed position; or limiting the movement of the first swing switch 11 and the second swing switch 21 at the same time to prevent the first swing switch 11 and the second swing switch 21 from being in the closed position.
[0071] See also Figure 4 and Figure 6 In some embodiments, a limited area 101 is defined between the first relay 10 and the second relay 20. When the first swing switch 11 is in the closed position, at least a portion of the first transmission member 30 is located in the limited area 101. When the second swing switch 21 is in the closed position, at least a portion of the second transmission member 40 is located in the limited area 101. The first transmission member 30 and the second transmission member 40 are configured to form a mutual abutting force to limit the continued movement of the first transmission member 30 and / or the second transmission member 40 and prevent the first swing switch 11 and / or the second swing switch 21 from continuing to swing to the closed position. Specifically, when the first swing switch 11 is in the closed position, the first transmission member 30 can be entirely or partially located in the limited area 101; when the second swing switch 21 is in the closed position, the second transmission member 40 can be entirely or partially located in the limited area 101.
[0072] When the first swing switch 11 and the second swing switch 21 attempt to be in the closed position at the same time, the first transmission member 30 and the second transmission member 40 attempt to stay in the limit area 101 at the same time. However, the mutual force between the first transmission member 30 and the second transmission member 40 forces at least one of the first transmission member 30 and the second transmission member 40 to leave the limit area 101, preventing at least one of the first swing switch 11 and the second swing switch 21 from being in the closed position, thereby achieving mechanical interlocking of the first relay 10 and the second relay 20.
[0073] in, Figure 4 and Figure 6 FIG. 1 shows an imaginary state of the relay assembly 100 when both the first swing switch 11 and the second swing switch 21 are switched to the closed position; FIG. Figure 4 In the figure, the first transmission member 30 and the second transmission member 40 have a partial structural overlap (the dotted portion of the first transmission member 30 and the second transmission member 40 in the figure). Therefore, in actual state, the first transmission member 30 and the second transmission member 40 restrict each other and cannot switch the first swing switch 11 and the second swing switch 21 to the closed position at the same time; Figure 6 The first transmission member 30 and the second transmission member 40 respectively have partial structures that overlap with the slider 50 (the dotted parts of the first transmission member 30 and the second transmission member 40 in the figure). Therefore, in the actual state, the first transmission member 30 and the second transmission member 40 restrict each other through the slider 50, and the first swing switch 11 and the second swing switch 21 cannot be switched to the closed position at the same time.
[0074] See also Figure 3 and Figure 5 It is understood that in some embodiments, when the first swing switch 11 is in the on position, the first transmission member 30 is located outside the limiting area 101. When the second swing switch 21 is in the on position, the second transmission member 40 is located outside the limiting area 101.
[0075] It can be understood that in some embodiments, the mutual abutment force between the first transmission member 30 and the second transmission member 40 includes: the pressure applied by the first transmission member 30 and the second transmission member 40 to each other through direct or indirect abutment, or the magnetic force exerted directly or indirectly by the first transmission member 30 and the second transmission member 40 on each other, etc.
[0076] See also Figures 3 to 6 In some embodiments, when the first transmission member 30 is first located in the limiting region 101, the first transmission member 30 is configured to prevent the second transmission member 40 from further entering the limiting region 101, thereby preventing the second swing switch 21 from switching to the closed position. When the second transmission member 40 is first located in the limiting region 101, the second transmission member 40 is configured to prevent the first transmission member 30 from further entering the limiting region 101, thereby preventing the first swing switch 11 from switching to the closed position.
[0077] When one of the first swing switch 11 and the second swing switch 21 is first in the closed position, the corresponding one of the first transmission member 30 and the second transmission member 40 is first located in the limit area 101, thereby stopping the other of the first transmission member 30 and the second transmission member 40 from continuing to enter the limit area 101, so as to restrict the corresponding other of the first swing switch 11 and the second swing switch 21 from switching to the closed position, thereby realizing mechanical interlocking of the first relay 10 and the second relay 20.
[0078] In some embodiments, when the first transmission member 30 is first located in the restricted area 101, the second transmission member 40 is configured to enter the restricted area 101 and push the first transmission member 30 out of the restricted area 101, thereby switching the first swing switch 11 to the open position and the second swing switch 21 to the closed position. When the second transmission member 40 is first located in the restricted area 101, the first transmission member 30 pushes the second transmission member 40 out of the restricted area 101, thereby switching the second swing switch 21 to the open position and the first swing switch 11 to the closed position.
[0079] When one of the first swing switch 11 and the second swing switch 21 is first in the closed position, the corresponding one of the first transmission member 30 and the second transmission member 40 is first located in the limit area 101. At this time, when the other of the first swing switch 11 and the second swing switch 21 switches to the closed position, the corresponding one of the first transmission member 30 and the second transmission member 40 moves toward the limit area 101, first pushing the one of the first transmission member 30 and the second transmission member 40 originally in the limit area 101 out of the limit area 101, and then driving the one of the first swing switch 11 and the second swing switch 21 that cooperates with it to switch to the open position; then, the other of the first transmission member 30 and the second transmission member 40 that enters the limit area 101 later stays in the limit area 101, and the other of the first swing switch 11 and the second swing switch 21 that cooperates with it switches smoothly to the closed position. Therefore, when one of the first swing switch 11 and the second swing switch 21 is in the closed position first and the other is switched to the closed position later, the one that is in the closed position first will be forced to switch to the open position, thereby achieving mechanical interlocking of the first relay 10 and the second relay 20.
[0080] In some embodiments, when the first transmission member 30 and the second transmission member 40 enter the limit area 101 at the same time, the first transmission member 30 and the second transmission member 40 are configured to be able to press against each other to limit the first transmission member 30 and the second transmission member 40 from continuing to move and prevent the first swing switch 11 and the second swing switch 21 from continuing to swing to the closed position.
[0081] When the first transmission member 30 and the second transmission member 40 both move toward the limit area 101, the first transmission member 30 and the second transmission member 40 stop each other and prevent each other from continuing to move, so that the first transmission member 30 and the second transmission member 40 cannot move into place, so that the first swing switch 11 and the second swing switch 21 cannot be switched to the closed position, thereby realizing mechanical interlocking of the first relay 10 and the second relay 20.
[0082] See also Figure 3 and Figure 4In some embodiments, the first transmission member 30 is provided with a first limiting portion 31. The first limiting portion 31 protrudes perpendicularly to the swing direction of the first transmission member 30. The second transmission member 40 is provided with a second limiting portion 41. The second limiting portion 41 protrudes perpendicularly to the swing direction of the second transmission member 40. The first limiting portion 31 and the second limiting portion 41 are configured to form a mutual abutting force to limit the movement of the first swing switch 11 and / or the second swing switch 21 and prevent the first swing switch 11 and the second swing switch 21 from being in the closed position at the same time.
[0083] The first limiting portion 31 extends perpendicularly to the direction of movement of the first transmission member 30, so that the side of the first limiting portion 31 facing the direction of movement of the first transmission member 30 extends in the non-moving direction. This helps increase the area of the first transmission member 30 mating with the second transmission member 40. The second limiting portion 41 extends perpendicularly to the direction of movement of the second transmission member 40, so that the side of the second limiting portion 41 facing the direction of movement of the second transmission member 40 extends in the non-moving direction. This helps increase the area of the second transmission member 40 mating with the first transmission member 30. The abutment between the first limiting portion 31 and the second limiting portion 41 helps improve the stability of the mutual engagement between the first transmission member 30 and the second transmission member 40, thereby enhancing the stability of the mechanical interlocking of the first relay 10 and the second relay 20.
[0084] See also Figure 3 and Figure 5 It can be understood that in some embodiments, when the first transmission member 30 and the second transmission member 40 are limited by abutting each other, the first limiting portion 31 and the second limiting portion 41 can abut directly or indirectly through other structures.
[0085] See also Figure 5 and Figure 6 In some embodiments, the relay assembly 100 further includes a slider 50. The slider 50 is slidably disposed between the first transmission member 30 and the second transmission member 40. The first transmission member 30 and the second transmission member 40 are configured to mutually limit the movement of the first swing switch 11 and / or the second swing switch 21 by pushing the slider 50, thereby preventing the first swing switch 11 and the second swing switch 21 from being in the closed position at the same time. When the first transmission member 30 pushes the slider 50, the movement direction of the slider 50 is opposite to that when the second transmission member 40 pushes the slider 50.
[0086] By setting the slider 50, the first transmission member 30 and the second transmission member 40 indirectly cooperate to limit by pushing the slider 50, so that the setting positions of the first transmission member 30 and the second transmission member 40 are more diverse, which is conducive to enabling the relatively set first relay 10 and the second relay 20 to adjust the specific setting positions according to actual needs.
[0087] In some embodiments, the slider 50 has a first mating portion 51 and a second mating portion 52. The first mating portion 51 protrudes perpendicularly to the swing direction of the first transmission member 30. The first transmission member 30 is configured to abut the first mating portion 51 and push the slider 50. The second mating portion 52 protrudes perpendicularly to the swing direction of the second transmission member 40. The second transmission member 40 is configured to abut the second mating portion 52 and push the slider 50.
[0088] The first mating portion 51 extends perpendicularly to the direction of movement of the first transmission member 30, extending toward a side of the first transmission member 30 in the non-moving direction of the first transmission member 30. This helps increase the area of the slider 50 that engages with the first transmission member 30. The second mating portion 52 extends perpendicularly to the direction of movement of the second transmission member 40, extending toward a side of the second transmission member 40 in the non-moving direction of the second transmission member 40. This helps increase the area of the slider 50 that engages with the second transmission member 40. The slider 50 abuts the first transmission member 30 through the first mating portion 51 and the second transmission member 40 through the second mating portion 52. This helps improve the stability of the mutual engagement between the slider 50 and the first transmission member 30, and between the slider 50 and the second transmission member 40, thereby enhancing the stability of the mechanical interlocking between the first relay 10 and the second relay 20.
[0089] See also Figure 3 and Figure 5 It can be understood that in some embodiments, the first limiting portion 31 abuts against the first matching portion 51 to push the slider 50 , and the second limiting portion 41 abuts against the second matching portion 52 to push the slider 50 .
[0090] See also Figure 5 、 Figure 7 and Figure 8 In some embodiments, the relay assembly 100 further includes a sliding seat 60 . The sliding seat 60 is fixed relative to the first relay 10 and the second relay 20 . The slider 50 is slidably disposed on the sliding seat 60 .
[0091] By providing the sliding seat 60 to slide with the slider 50 , the sliding stability of the slider 50 is improved, and the setting position of the slider 50 is easily adjusted to adapt to the setting positions of the first relay 10 and the second relay 20 .
[0092] In some embodiments, the relay assembly 100 further includes a stopper 70. The slider 50 is provided with a strip-shaped hole 53. The stopper 70 passes through the strip-shaped hole 53 and is connected to the sliding seat 60. When the stopper 70 abuts against the wall of the strip-shaped hole 53, the slider 50 is restricted from sliding further.
[0093] The limit member 70 is connected to the sliding seat 60, and the limit member 70 passes through the strip hole 53 of the slider 50. When the slider 50 slides, the position of the limit member 70 relative to the slider 50 is constrained by the strip hole 53, thereby constraining the sliding range of the slider 50 relative to the sliding seat 60, so that the slider 50 and the sliding seat 60 can be stably matched, thereby improving the sliding stability of the slider 50.
[0094] As an illustrative example, the limiting member 70 includes but is not limited to a bolt, a pin, a buckle, etc.
[0095] In some embodiments, the relay assembly 100 further includes a rolling member 80. The rolling member 80 is disposed between the sliding seat 60 and the slider 50. The rolling member 80 and the slider 50 are in rolling engagement with each other. The rolling member 80 and the sliding seat 60 are in rolling engagement with each other.
[0096] When the slider 50 slides relative to the sliding seat 60, the slider 50 and the rolling member 80 roll together, and the sliding seat 60 and the rolling member 80 roll together, thereby reducing the friction between the slider 50 and the sliding seat 60, which is beneficial to reducing the obstruction to the limiting cooperation between the first transmission member 30 and the second transmission member 40, so as to improve the stability of the mechanical interlocking of the first relay 10 and the second relay 20.
[0097] It is understood that in some embodiments, the rolling element 80 is a ball bearing. The ball bearing can rotate in any direction to reduce the resistance to the sliding of the slider 50. In other embodiments, the rolling element 80 can be a roller or other structure that can roll relative to the slider 50 and the sliding seat 60.
[0098] In some embodiments, the sliding seat 60 is provided with a limiting groove 61 . The rolling element 80 is disposed in the limiting groove 61 to constrain the relative position of the rolling element 80 .
[0099] 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.
