[0001] This application claims priority from Chinese Utility Model Application No 202210273079.X filed 18 March 2022. The entire content of this priority application is
hereby incorporated by reference.
[0002] The present disclosure relates to an operation mechanism for a dual-power switch and a dual-power switch.
[0003] Dual-power switches are widely used in industrial field, especially in emergency power supply system. Based on the status of the power supply circuit, a
dual-power switch can switch the load circuit from one power supply to another, for example,
between the commercial power supply and the standby power supply, thus maintaining the
continuous and reliable operation of the load circuit.
[0004] At present, the dual-power switches are divided into two-stage (two-position)
and three-stage (three-position) according to its working positions (also known as working
stages). The two-stage dual-power switch is divided into two working positions: a common
power supply and a standby power supply, which ensures that the load is always connected
with one power supply, and the power is cut off only during the switching period (usually
-100 ms). The two-stage dual-power switch cannot cut off both power supplies at the same
time. The three-stage dual-power switch is divided into three working positions: common
power supply, zero position and standby power supply, and the middle zero position can be
called dual-separation position, which can ensure the long-term disconnection between the
load and the two power supplies. A controller determines whether the three-stage dual-power
switch remains in the middle zero position and how long it remains in the middle zero position. Generally speaking, the controller can provide delay control of 0-300 s. The middle zero position provides a buffer time for the switching process of dual power automatic switch, which is beneficial to arc extinguishing and ensures the safety of the whole switching process.
[0005] A traditional middle zero position keeping solution is to use an independent power blocking mechanism, which has high cost and complex structure. Another traditional
solution uses friction to keep the middle position, so the reliability is not high.
[00061 Therefore, there is a need for a dual-power switch that can reliably switch and
maintain the middle position.
[00071 The present disclosure provides an operation mechanism for a dual-power
switch and a dual-power switch. Such an operation mechanism can ensure that the
dual-power switch can perform reliable switching and stably maintain the middle position,
and is of simple structure and low cost.
[00081 In one aspect, the present disclosure provides an operation mechanism for a
dual-power switch. The operation mechanism is used for driving the breaking unit of the
dual-power switch, so that the dual-power switch can be switched between a dual-separation
state, a first power-on state and a second power-on state. The operation mechanism is
characterized in that, the operation mechanism comprises: a rotation shaft, arranged on a
housing of the dual-power switch along a rotation axis; a first driving member, arranged on
the rotation shaft and can rotate around the rotation shaft in a first direction and a second
direction which are opposite to each other; a second driving member, arranged on the rotation
shaft, connected to the breaking unit, and can rotate around the rotation shaft between a
dual-separation position, a first power-on position and a second power-on position under the
driving of the first driving member; a stop member, arranged on the frame of the housing and
can move between a locking position and an unlocking position under the driving of the first
driving member, wherein in the locking position, the stop member keeps the second driving
member near the dual-separation position; in the unlocking position, the stop member does
not block the second driving member; and an elastic member, arranged between the stop member and the frame and elastically biasing the stop member to the locking position, wherein the first driving member drives the second driving member to rotate after rotating by an idle stroke, and the second driving member further drives the breaking unit to switch the state of the dual-power switch; and wherein the first driving member drives the stop member to move from the locking position to the unlocking position when rotating by the idle stroke.

[0015] In an embodiment, the second driving member further comprises a protrusion arranged on the second body, wherein the protrusion extends along the radial direction and is outside the recess, wherein the first stop member and the second stop member can stop the movement of the protrusion.
[00161 In an embodiment, the first stop member comprises a first body and a first stop portion extending from the first body along the direction of the rotation axis toward the protrusion, and the second stop member comprises a second body and a second stop portion extending from the second body along the direction of the rotation axis toward the protrusion, wherein the first stop portion and the second stop portion are used for stopping the movement of the protrusion.

[0033] The drawings in this specification are schematic views to assist in explaining the concept of the present disclosure, and schematically show the shapes of various parts and

[0034] Hereinafter, with reference to figs. 1 to 7, preferred embodiments according to
the present disclosure will be described in detail.
[0035] Fig. 1 shows an exploded view of an operation mechanism for a dual-power
switch according to an embodiment of the present disclosure. The operation mechanism is
used for driving a breaking unit of the dual-power switch, so that the dual-power switch can
be switched between a dual-separation state, a first power-on state and a second power-on
state.
[0036] As shown in Figs. 1 and 2, the operation mechanism comprises a rotation shaft
3, a first driving member 1, a second driving member 2, stop members, and elastic members.
[00371 The rotation shaft 3 is arranged on a housing (not shown in the figures) of a dual-power switch, such as the housing of the breaking unit of the dual-power switch, along a
rotation axis (as shown by the dotted line A in Fig. 1). The first driving member 1 is arranged
on the rotation shaft 3 and can rotate around the rotation shaft 3 in a first direction and a
second direction opposite to each other. The second driving member 2 is arranged on the
rotation shaft 3, connected to the breaking unit, and can rotate around the rotation shaft 3
under the driving of the first driving member between a dual-separation position, a first
power-on position and a second power-on position, which respectively correspond to the dual-separation state, the first power-on state and the second power-on state of the dual-power switch.
[00381 The stop members are arranged on the frame of the housing and can move between a locking position and an unlocking position under the driving of the first driving member 1. The stop members are arranged on a fixed frame 4 of the housing of the breaking unit. In other embodiments, the stop members are arranged on a fixed frame on a side plate of the operation mechanism. In the locking position, the stop members keep the second driving member 2 near the dual-separation position. In the unlocking position, a stop member does not block the second driving member 2, that is, exits the moving path of the second driving member 2. The elastic member is arranged between the stop member and the frame and elastically biases the stop member to the locking position.
[0039] The first driving member 1, after rotating for an idle rotation, drives the second driving member 2 to rotate, and the second driving member 2 further drives the breaking unit to switch the state of the dual-power switch. The first driving member 1 drives the stop member to move from the locking position to the unlocking position when rotating by the idle stroke.
[0040] In addition, the operation mechanism further comprises a driving rod 5, which is arranged on the second driving member 2, and the second driving member 2 is connected to the breaking unit through the driving rod 5. As shown in fig. 1, the driving rod 5 can extend in a direction parallel to the rotation axis, so that the rotation of the second driving member can drive the breaking unit to move.
[0041] For example, the stop members comprise a first stop member 6 and a second stop member 7 which are arranged rotatably on the frame 4 of the housing and are arranged with respect to each other in a mirroring manner, and the elastic members comprise a first elastic member 8 and a second elastic member 9. The first elastic member 8 exerts an elastic biasing force on the first stop member 6, for example, in the clockwise direction in Fig. 2. The second elastic member 9 exerts an elastic biasing force on the second stop member 7, for example, in the counterclockwise direction in Fig. 2. The first stop member 6 and the second stop member 7, when in the locking position, prevent the second driving member 2 from rotating from the dual-separation position to the first power-on position or the second power-on position.
[0042] As shown in Figs. 3 to 7, the first driving member 1 comprises a first driving surface 11 and a second driving surface 12, and the second driving member 2 comprises a
first driven surface 21 that can cooperate with the first driving surface 11 and a second driven
surface 22 that can cooperate with the second driving surface 12.
[0043] As shown in Figs. 1 and 3 to 7, thefirst driving member 1 comprises a first
body 13 and a first boss 14 arranged on thefirst body 13 and extending in a radial direction
perpendicular to the rotation axis, and two side surfaces of the first boss 14 form the first
driving surface 11 and the second driving surface 12. The first body 13 may have a disk shape
or other shapes, which is not limited by the present disclosure.
[0044] As shown in Figs. 1 and 3 to 7, the second driving member 2 comprises a
second body 23 and a recess 24 arranged on the second body 23 and extending in the radial
direction, and two side surfaces of the recess 24 form the first driven surface 21 and the
second driven surface 22. In the assembled state of the operation mechanism, the first boss 14
is inserted into the recess 24. The second body 23 may have a disk shape or other shapes,
which is not limited by the present disclosure.
[0045] As shown in Figs. 1 and 3 to 7, thefirst driving member 1 further comprises a
second boss 15 arranged on the first body 13, which extends in the radial direction and is
outside (i.e., radially outside) the first boss 14, and is located between the first body 13 and
the first boss 14 along the direction of the rotation axis. The second boss 15 can drive the first
stop member 6 and the second stop member 7 to move respectively between their respective
locking positions and unlocking positions.
[0046] As shown in Figs. 1 and 3 to 7, the second driving member 2 further
comprises a protrusion 25 provided on the second body 23, which extends in the radial
direction and is outside (i.e., radially outside) the recess 24. The first stop member 6 and the
second stop member 7 can stop the movement of the protrusion 25.
[00471 As shown in Figs. 1 and 2, the first stop member 6 comprises a first body 61
and a first stop portion 62 extending from the first body 61 toward the protrusion 25 in the
direction of the rotation axis, and the second stop member 7 comprises a second body 71 and
a second stop portion 72 extending from the second body 71 toward the protrusion 25 in the direction of the rotation axis. The first stop portion 62 and the second stop portion 72 are used to stop the movement of the protrusion 25, so as to stop the second driving member 2.
[0048] The first driving member 1 can rotate around the rotation shaft 3 between an initial position, a first position, and a second position, which correspond to the
dual-separation position, the first power-on position, and the second power-on position of the
second driving member 2.
[0049] Next, with reference to the drawings, how the action of the operation mechanism can realize the state transition of the dual-power switch is described. Figs. 3 to 5
depict the action of the operation mechanism in the process of the dual-power switch
switching from the dual-separation state to the first power-on state. Figs. 5 to 7 depict the
action of the operation mechanism in the process of the dual-power switch switching from the
first power-on state to the dual-separation state.
[0050] As shown in Figs. 3 to 4, the first driving surface 11 contacts the first driven
surface 21 after the first driving member 1 rotates by a first idle stroke from the initial
position in a first direction (i.e., counterclockwise in the figure). In this process, the second
boss 15 abuts against the first body 61 of the first stop member 6, and overcomes the elastic
biasing force exerted by the first elastic member 8 to drive the first stop member 6 to rotate
from the locking position to the unlocking position in the first direction, so that the first stop
portion 62 no longer blocks the movement of the protrusion 25.
[0051] As shown in Figs. 4 to 5, when the first driving member 1 continues to rotate
in the first direction to the first position, the first driving member 1 drives the second driving
member 2 to rotate in the first direction from the dual-separation position to the first
power-on position, so that the dual-power switch is switched from the dual-separation state to
the first power-on state. In this process, the second boss 15 is always overcoming the elastic
biasing force exerted by the first elastic member 8 in the former stage to keep the first stop
member 6 in the unlocking position, so that the second driving member 2 can follow the first
driving member 1 to rotate in the first direction. In the latter stage, the second boss 15 no
longer abuts against the first body 61 of the first stop member 6, and the first stop member 6
returns to its locking position under the action of the first elastic member 8. Since neither the
first body 61 nor the first stop portion 62 of the first stop member 6 are on the moving path of the protrusion 25 of the second driving member 2, the second driving member 2 can rotate to the first power-on position under the drive of the first driving member 1.
[0052] As shown in Figs. 5 to 6, the second driving surface 12 contacts the second driven surface 22 after the first driving member 1 rotates from the first position in the second
direction (i.e., clockwise in the figure) by a third idle stroke. Similarly, in this process, the
second boss 15 abuts against the first body 61 of the first stop member 6, and overcomes the
elastic biasing force exerted by the first elastic member 8 to drive the first stop member 6 to
rotate from the locking position to the unlocking position in the first direction, thus the
movement of the protrusion 25 is no longer blocked.
[00531 As shown in Figs. 6 to 7, when the first driving member 1 continues to rotate
in the second direction to the initial position, the first driving member 1 drives the second
driving member 2 to rotate in the second direction from the first power-on position to the
dual-separation position, so that the dual-power switch is switched from the first power-on
state to the dual-separation state. In this process, the first driving member 1 rotates to the
initial position set horizontally in Fig. 7, and it does not move any more. In the initial position,
the second boss 15 no longer abuts against the first body 61 of the first stop member 6, so that
the first stop member 6 returns to its locking position under the action of the first elastic
member 8. In addition, after the first driving member 1 rotates to the initial position, the
second driving member 2 continues to move in the second direction due to the power
provided by the first driving member 1. However, due to the stop provided by the first stop
portion 6 of the first stop member 6 and the second stop portion 72 of the second stop
member 7 in the two directions, the second driving member 2 will bounce between the first
stop portion 6 and the second stop portion 72 until it is completely kept in the dual-separation
position.
[0054] The action of the operation mechanism in the process of the dual-power switch
switching from the dual-separation state to the second power-on state is similar to that
described above with respect to Figs. 3 to 5, and the action of the operation mechanism in the
process of the dual-power switch switching from the second power-on state to the
dual-separation state is similar to that described above with respect to Figs. 5 to 7. No
schematic views are provided here, and the process is described only in words.
[0055] After the first driving member 1 rotates in the second direction (clockwise in the figure) from the initial position by a second idle stroke, the second driving surface 12 contacts the second driven surface 22. In this process, the second boss 15 abuts against the second body 71 of the second stop member 7, and overcomes the elastic biasing force exerted by the second elastic member 9 to drive the second stop member 7 to rotate in the second direction from the locking position to the unlocking position, so that the second stop portion 72 no longer blocks the movement of the protrusion 25.
[0056] When the first driving member 1 continues to rotate in the second direction to the second position, the first driving member 1 drives the second driving member 2 to rotate in the second direction from the dual-separation position to the second power-on position, so that the dual-power switch is switched from the dual-separation state to the second power-on state. In this process, the second boss 15 is always overcoming the elastic biasing force exerted by the second elastic member 9 in the former stage to keep the second stop member 7 in the unlocking position, so that the second driving member 2 can follow the first driving member 1 to rotate in the second direction. In the latter stage, the second boss 15 no longer abuts against the second body 71 of the second stop member 7, and the second stop member 7 returns to its locking position under the action of the second elastic member 9. Since neither the second body 71 nor the second stop portion 72 of the second stop member 7 are on the moving path of the protrusion 25 of the second driving member 2, the second driving member 2 can rotate to the second power-on position under the drive of the first driving member 1.
[00571 After the first driving member 1 rotates from the second position in the first direction by the third idle stroke, the first driving surface 11 contacts the first driven surface 21. Similarly, in this process, the second boss 15 abuts against the second body 71 of the second stop member 7, and overcomes the elastic biasing force exerted by the second elastic member 9 to drive the second stop member 7 to rotate in the second direction from the locking position to the unlocking position, thus the movement of the protrusion 25 is no longer blocked.
[0058] When the first driving member 1 continues to rotate in the first direction to the initial position, the first driving member 1 drives the second driving member 2 to rotate in the first direction from the second power-on position to the dual-separation position, so that the dual-power switch is switched from the second power-on state to the dual-separation state. In this process, the first driving member 1 rotates to the initial position set horizontally in Fig. 7, and it does not move any more. In the initial position, the second boss 15 no longer abuts against the second body 71 of the second stop member 7, so that the second stop member 7 returns to its locking position under the action of the second elastic member 9. In addition, after the first driving member 1 rotates to the initial position, the second driving member 2 continues to move in the first direction due to the power provided by the first driving member 1. However, due to the stop provided by the first stop portion 62 of the first stop member 6 and the second stop portion 72 of the second stop member 7 in the two directions, the second driving member 2 will bounce between the first stop portion 62 and the second stop portion 72 until it is completely kept in the dual-separation position.
[0059] As shown in Figs. 3 to 4, the first idle stroke is the rotation angle of the first driving surface 11 in the process of traveling from the initial position to a position in contact with the first driven surface 21, and the second idle stroke is the rotation angle of the second driving surface 11 in the process of traveling from the initial position to a position in contact with the second driven surface 21. The first idle stroke and the second idle stroke may have the same rotation angle. As shown in Figs. 5 to 6, the third idle stroke is the rotation angle of the second driving surface 12 in the process of traveling from the first position to a position in contact with the second driven surface 22, or the rotation angle of the first driving surface 11 in the process of traveling from the second position to a position in contact with the first driven surface 21.
[0060] Through the initial idle rotation of the first driving member realized by the above structure, the operation mechanism of the present disclosure can quickly and reliably obtain a stable middle dual-separation state, and can reliably switch from the intermediate dual-separation state to the first power-on state or the second power-on state. In addition, the operation mechanism of the present disclosure is simple in structure and low in cost.
