Description

Technical Field

[0001] The present application relates to the technical field of low-voltage electrical appliances, and in particular to an operating mechanism, a transfer switch and a power distribution device. Background Art

[0002] The transfer switch can automatically switch to another backup power supply when one power supply fails, thereby achieving uninterrupted power supply and ensuring the normal operation of equipment. It has been widely used in electrical systems in residential, commercial and industrial buildings, especially in emergency power supply systems.

[0003] At present, transfer switches are divided into two-stage (two-station) and three-stage (three-station) according to their working positions (also known as working sections). The two-stage transfer switch is divided into two working positions: the normal power supply and the backup power supply, to ensure that the load is always connected to one power supply and is only powered off during the conversion period (usually 50-100ms). The two-stage transfer switch cannot cut off two power supplies at the same time. The three-stage transfer switch is divided into three working positions: the normal power supply, the middle zero position, and the backup power supply. The middle zero position is also called the double split position, which can ensure that the load is disconnected from the two power supplies at the same time, and the controller decides whether the load needs to be transferred to the backup power supply. The middle zero position provides a buffer time for the conversion process of the transfer switch, which is conducive to ensuring the safety of the entire conversion process.

[0004] However, when the operating mechanism of the existing switching switch is switched from the closed position to the open position, the output member of the operating mechanism is easily impacted by the rotational inertia of the moving contact, resulting in excessive rotation angle or failure to smoothly stop at the open position, which is not conducive to circuit protection.

[0008] The operating mechanism also includes a first driving member and a second driving member that are independently driven and cooperated with the output member respectively. The first driving member is driven to drive the first stop member to move to release the abutment with the output member, and drive the output member to switch between the double open position and the normal closing position.

When the second limit part is released from the abutment with the output member, the reset member is driven to store energy so that the reset member has a tendency to drive the second limit part to abut against the output member.

[0011] Optionally, the reset member is a tension spring, and two ends of the tension spring are respectively connected to the first limiting portion and the second limiting portion.

[0012] Optionally, the first stopper also includes a first triggering portion connected to the first limiting portion, the first driving member cooperates with the first triggering portion, and the first driving member is driven by the first triggering portion to drive the first limiting portion to move to release the abutment with the output member, so that the first driving member drives the output member to switch from the double-open position to the normal closing position;

[0013] The second stop member also includes a second triggering portion connected to the second limiting portion, and the second driving member cooperates with the second triggering portion. The second driving member is driven by the second triggering portion to drive the second limiting portion to move to release the abutment with the output member, so that the second driving member drives the output member to switch from the double-open position to the standby closing position.

[0014] Optionally, the output member is rotatably mounted on the mounting base, a first arc groove and a second arc groove are formed on the output member, the first driving member is slidably disposed in the first arc groove, and the second driving member is slidably disposed in the second arc groove;

[0015] A side of the first trigger portion close to the first driving member is a first arcuate surface, and the curvature of the first arcuate surface is the same as the curvature of the first arcuate groove, so that the first driving member drives the first trigger portion to move when it is driven to slide. A side of the second trigger portion close to the second driving member is a second arcuate surface, and the curvature of the second arcuate surface is the same as the curvature of the second arcuate groove, so that the second driving member drives the second trigger portion to move when it is driven to slide.

[0016] Optionally, the output member has a convex portion, the first limiting portion has a first limiting protrusion, and the second limiting portion has a second limiting protrusion. When the output member is in the double-open position, the convex portion abuts against the first limiting protrusion and the second limiting protrusion, respectively. When the output member is in the normal closing position and the standby closing position, the convex portion releases the abutment against the first limiting protrusion and the second limiting protrusion, respectively.

[0020] The beneficial effects of this application include:

[0021] The present application provides an operating mechanism, a switching switch and a power distribution device, including a mounting base and an output member movably mounted on the mounting base, a first stopper and a second stopper, wherein the first stopper and the second stopper are respectively located on opposite sides of the output member to limit the displacement of the output member from different directions, thereby enabling the output member to be driven to smoothly switch between a double-open position, a common closing position and a standby closing position. Specifically, by setting the output member to abut against the first stopper and the second stopper when it is in the double-open position, and to release the abutment from the first stopper and the second stopper when it is in the common closing position and the standby closing position, when the output member switches from the double-open position to the common closing position or the standby closing position, the first stopper and the second stopper do not block the switching process, and when the output member switches from the common closing position or the standby closing position to the double-open position, the first stopper and the second stopper abut against the opposite sides of the output member, thereby ensuring that the output member reliably stops at the double-open position. In addition, the operating mechanism also includes a first driving member and a second driving member that are independently driven and cooperated with the output member.

The second driving member is driven to drive the second stop member to move to release the abutment with the output member, and drive the output member to switch between the double open position and the standby closed position. The introduction of these two independent driving members enriches the driving mechanism of the operating mechanism, improves the flexibility and controllability of the product, and helps prevent the output member from unstable movement during position conversion.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. It should be noted that, in the absence of conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0035] In the description of the present application, it should be noted that the directions or positional relationships indicated by the terms "upper" and "lower" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] Driven by intelligent and automated high-tech, the smart home industry has entered a period of rapid development. The smart home industry is facing new challenges and opportunities in the transformation of technology, market and industry.

[0038] According to the function, the smart home can be divided into eight modules: entertainment system, security system, control system, lighting system, kitchen and bathroom appliance system, network and communication system, health care system, and indoor environment system. The eight modules work together to realize the whole house intelligence.

[0039] In this digital age, people are becoming more and more dependent on electricity. Whether it is home, industry or business, a stable and reliable power supply is essential. Among them, the transfer switch can automatically switch to another backup power supply when one power source fails, thereby achieving uninterrupted power supply and ensuring the normal operation of equipment. Therefore, it is often used in important power distribution occasions.

[0040] However, there are some problems with the existing transfer switches when switching from the closed position to the open position. Specifically, the operating mechanism is susceptible to the impact of the rotational inertia of the moving contact during this switching process. This may cause the output member 200 of the operating mechanism to rotate too much or fail to stably stop at the open position, thereby adversely affecting the protection of the circuit. This phenomenon may cause a series of problems, including equipment damage, unstable power supply, and unexpected impact on the load during the switching process.

[0041] In order to solve the above problems, the present application embodiment provides an operating mechanism, such as Figure 1 and Figure 2As shown, the operating mechanism includes a mounting base 100 and an output member 200 movably mounted on the mounting base 100, a first stop member 300 and a second stop member 400, wherein the first stop member 300 and the second stop member 400 are respectively located on opposite sides of the output member 200 to limit the displacement of the output member 200 from different directions, thereby enabling the output member 200 to be driven to smoothly switch between the double-open position, the normal closing position and the standby closing position. Specifically, by arranging that the output member 200 is in contact with the first stop member 300 and the second stop member 400 respectively when it is in the double-open position, and releasing the contact with the first stop member 300 and the second stop member 400 respectively when it is in the normal closing position and the backup closing position, when the output member 200 is converted from the double-open position to the normal closing position or the backup closing position, the first stop member 300 and the second stop member 400 do not block its conversion process, and when the output member 200 is converted from the normal closing position or the backup closing position to the double-open position, the first stop member 300 and the second stop member 400 abut against the opposite sides of the output member 200, it can be ensured that the output member 200 stops reliably in the double-open position, and the possibility of short circuit caused by the normal power supply and the backup power supply being connected at the same time is effectively avoided.

[0042] like Figure 1 and Figure 2 As shown, the operating mechanism also includes a first driving member 600 and a second driving member 700 which are independently driven and cooperated with the output member 200, that is, when the first driving member 600 is driven to drive the output member 200 to change its position, the second driving member 700 does not move, and when the second driving member 700 is driven to drive the output member 200 to change its position, the first driving member 600 does not move. The introduction of these two independent driving members enriches the driving mechanism of the operating mechanism and improves the flexibility and controllability of the entire system. Specifically, the first driving member 600 is driven to drive the first stop member 300 to move so as to release the abutment with the output member 200, and to drive the output member 200 to switch between the double-open position and the normal closing position. The second driving member 700 is driven to drive the second stop member 400 to move so as to release the abutment with the output member 200, and to drive the output member 200 to switch between the double-open position and the standby closing position. This independent drive design not only helps to reduce the inertial force impact on the output member 200 during the switching process, but also can more flexibly adjust the movement trajectory of the output member 200, provide more control means for the smooth operation of the operating mechanism, and help prevent the output member 200 from unstable movement when switching to the double-open position.

[0043] It should be noted that, under the drive of external force, the output member 200 can only be in any one of the double-open position, the normal closing position and the standby closing position at the same time. Since the operating mechanism can be applied to the transfer switch, at this time, the transfer switch should also be in the state corresponding to the position, that is, the double-open position of the output member 200 corresponds to the double-open position of the transfer switch, the normal closing position of the output member 200 corresponds to the normal closing position of the transfer switch, and the standby closing position of the output member 200 corresponds to the standby closing position of the transfer switch. It should be understood that the double-open position means that the switch body is disconnected from both the normal power supply and the standby power supply at this time; the normal closing position means that the switch body is connected to the normal power supply and disconnected from the standby power supply at this time; the standby closing position means that the switch body is connected to the standby power supply and disconnected from the normal power supply at this time.

[0044] Alternatively, if Figure 3 As shown, the first stop member 300 includes a first limiting portion 310, and the second stop member 400 includes a second limiting portion 410. When the output member 200 is located in the double-open position, it abuts against the first limiting portion 310 and the second limiting portion 410 respectively. Therefore, when the output member 200 is switched from the normal closing position or the standby closing position to the double-open position, the output member 200 can reliably stop at the double-open position; when the output member 200 is located in the normal closing position and the standby closing position, it releases the abutment against the first limiting portion 310 and the second limiting portion 410 respectively. Therefore, the first limiting portion 310 and the second limiting portion 410 do not affect the movement process of the output member 200 from the double-open position to the normal closing position or the standby closing position.

[0045] Alternatively, if Figures 1 to 3 As shown, the operating mechanism further includes a reset member 500 to provide additional control and recovery functions for the operating mechanism. The first limit portion 310 and the second limit portion 410 are connected via the reset member 500 to form a reset system. During the operation of the operating mechanism, when the first limiting portion 310 is driven by an external force to move in a direction away from the output member 200 and releases the contact with the output member 200, the reset member 500 can be driven to deform and store energy, so that the reset member 500 has a tendency to drive the first limiting portion 310 to contact the output member 200. Therefore, when the output member 200 is switched from the normal closing position to the double opening position, the reset member 500 can release energy to drive the first limiting portion 310 to move in the direction of the output member 200, so that the first limiting portion 310 and the output member 200 are contacted again, and when the first limiting portion 310 is actuated, the second limiting portion 410 is always inactive. At this time, the first limiting portion 310 and the second limiting portion 410 are respectively contacted with the opposite sides of the output member 200, which effectively limits the movement of the output member 200 when it is switched to the double opening position, thereby improving the reliability and stability of the operating mechanism.

[0046] Similarly, when the second limiting portion 410 is driven by an external force to move in a direction away from the output member 200 and releases the abutment with the output member 200, it can drive the reset member 500 to deform and store energy, so that the reset member 500 has a tendency to drive the second limiting portion 410 to abut against the output member 200. Therefore, when the output member 200 is switched from the standby closing position to the double-open position, the reset member 500 can release energy to drive the second limiting portion 410 to move in the direction of the output member 200, so that the second limiting portion 410 abuts against the output member 200 again, and when the second limiting portion 410 is actuated, the first limiting portion 310 does not actuate at all. At this time, the first limiting portion 310 and the second limiting portion 410 are respectively abutted against the opposite sides of the output member 200, effectively limiting the movement of the output member 200 when it is switched to the double-open position, thereby improving the reliability and stability of the operating mechanism.

[0047] Alternatively, if Figures 1 to 3 As shown, the reset member 500 is a tension spring, which is an elastic energy storage element. The two ends of the tension spring are respectively connected to the first limit portion 310 and the second limit portion 410, forming a compact and efficient reset system. Specifically, when the first limit portion 310 or the second limit portion 410 is released from the abutment with the output member 200, the tension spring is stretched and stores elastic potential energy, which makes the tension spring have a tendency to drive the first limit portion 310 or the second limit portion 410 to abut against the output member 200 again. Once the position of the output member 200 needs to be reset, the elastic potential energy of the tension spring is released, which can quickly and reliably drive the first limit portion 310 or the second limit portion 410 to abut against the output member 200 again, and realize automatic reset. It should be noted that during the operation of the operating mechanism, the firmness of the connection parts and the appropriate elasticity of the tension spring should be ensured so that the tension spring has sufficient elastic energy storage and energy release properties, thereby enabling the tension spring to provide sufficient elastic force during resetting, thereby ensuring that the first stop member 300 or the second stop member 400 can quickly and smoothly return to the predetermined working position.

[0048] In other embodiments, the reset member 500 may also be other elastic members such as a compression spring or a spring. For example, the reset member 500 is a compression spring, and the compression spring includes a first compression spring and a second compression spring, wherein the first compression spring applies an elastic biasing force to the first stopper 300, and the second compression spring applies an elastic biasing force to the second stopper 400. When the first limiting portion 310 or the second limiting portion 410 is released from contact with the output member 200, the first compression spring or the second compression spring is compressed and stores elastic potential energy, so that the first compression spring or the second compression spring has a tendency to drive the first limiting portion 310 or the second limiting portion 410 to contact the output member 200 again. Once the position of the output member 200 needs to be reset, the elastic potential energy of the first compression spring and the second compression spring is released, so that the first limiting portion 310 or the second limiting portion 410 can be quickly and reliably driven to contact the output member 200 again, thereby achieving automatic reset.

[0049] Alternatively, if Figure 3 As shown, the first stopper 300 also includes a first triggering portion 320 connected to the first limiting portion 310, and the first driving member 600 is driven to cooperate with the first triggering portion 320, so that the first driving member 600 is driven to drive the first triggering portion 320 to move, and the movement of the first triggering portion 320 drives the first limiting portion 310 to move in a direction away from the output member 200, that is, the external force acting on the first driving member 600 is accurately transmitted to the first limiting portion 310 through the first triggering portion 320, so that the first limiting portion 310 can be released from the abutment with the output member 200, and the output member 200 is no longer blocked by the first limiting portion 310, and the first driving member 600 can drive the output member 200 to move, and finally the output member 200 is converted from the double-open position to the common closing position;

[0050] Similarly, the second stop member 400 also includes a second trigger portion 420 connected to the second limit portion 410, which drives the second driving member 700 to cooperate with the second trigger portion 420, so that the second driving member 700 is driven to drive the second trigger portion 420 to move, and the movement of the second trigger portion 420 drives the second limit portion 410 to move in a direction away from the output member 200, that is, the external force acting on the second driving member 700 is accurately transmitted to the second limit portion 410 through the second trigger portion 420, so that the second limit portion 410 can be released from the abutment with the output member 200, and the output member 200 is no longer blocked by the second limit portion 410. The second driving member 700 can drive the output member 200 to move, and finally the output member 200 is converted from the double-open position to the standby closing position.

[0051] Alternatively, if Figure 1 and Figure 2 As shown, the output member 200 is rotatably mounted on the mounting base 100, that is, when the output member 200 is driven by an external force, it can rotate relative to the mounting base 100 to achieve the conversion of its position, such as Figure 4 As shown, by providing the first arc groove 210 and the second arc groove 220 on the output member 200, the first driving member 600 is slidably disposed in the first arc groove 210, and the second driving member 700 is slidably disposed in the second arc groove 220, so as to utilize the lengths of the first arc groove 210 and the second arc groove 220 to provide idle strokes for the first driving member 600 and the second driving member 700, respectively, so as to realize that the first driving member 600 and the second driving member 700 independently drive the output member 200. At the same time, the design of the first arc groove 210 and the second arc groove 220 enables the first driving member 600 and the second driving member 700 to have a fixed motion trajectory, so as to reduce the uncertainty of the two during the motion process, and form an efficient driving system.

[0052] At the same time, one end of the first trigger part 320 is hinged to the mounting base 100, and the side of the first trigger part 320 close to the first driving member 600 is constructed as a first curved surface 321, and the curvature of the first curved surface 321 is the same as the curvature of the first curved groove 210, so as to ensure that the first trigger part 320 can be driven to move when the first driving member 600 is driven to slide; similarly, one end of the second trigger part 420 is hinged to the mounting base 100, and the side of the second trigger part 420 close to the second driving member 700 is a second curved surface 421, and the curvature of the second curved surface 421 is the same as the curvature of the second curved groove 220, so that the second trigger part 420 can be driven to move when the second driving member 700 is driven to slide.

[0053] Alternatively, if Figures 1 to 4 As shown, the output member 200 has a convex portion 230, the first limiting portion 310 has a first limiting protrusion 311, and the second limiting portion 410 has a second limiting protrusion 411. When the output member 200 is in the double-open position, the convex portion 230 abuts against the first limiting protrusion 311 and the second limiting protrusion 411 respectively to limit the rotation of the output member 200. When the output member 200 is in the normal closing position and the standby closing position, the convex portion 230 releases the abutment with the first limiting protrusion 311 and the second limiting protrusion 411 respectively, thereby not blocking the rotation of the output member 200. It should be noted that the protrusion 230 can be a semi-annular protrusion 230 protruding along its outer periphery. When the output member 200 is in the double-open position, the two ends of the protrusion 230 are respectively abutted against the first limit protrusion 311 and the second limit protrusion 411. When the output member 200 is in the normal closing position and the standby closing position, the two ends of the protrusion 230 are respectively released from the abutment with the first limit protrusion 311 and the second limit protrusion 411.

[0054] Alternatively, if Figures 1 to 4As shown, the operating mechanism also includes a first energy storage member 800 drivingly matched with the first driving member 600 and a second energy storage member 900 drivingly matched with the second driving member 700. The first driving member 600 is driven to drive the first energy storage member 800 to store energy. During this process, the first driving member 600 slides from one end of the first arc groove 210 to the other end of the first arc groove 210, and does not drive the first arc groove 210 to rotate, that is, the output member 200 does not rotate. After the first energy storage member 800 passes the dead point position, the energy is released, and the first energy storage member 800 drives the first driving member 600 to move. The movement of the first driving member 600 drives the output member 200 to switch between the double-open position and the common closing position. Similarly, the second driving member 700 is driven to drive the second energy storage member 900 to store energy. During this process, the second driving member 700 slides from one end of the second arc groove 220 to the other end of the second arc groove 220, and does not drive the second arc groove 220 to rotate, that is, the output member 200 does not rotate. After the second energy storage member 900 passes the dead point position, the energy is released, and the second energy storage member 900 can drive the second driving member 700 to move. The movement of the second driving member 700 drives the output member 200 to switch between the double open position and the standby closing position.

[0055] Alternatively, if Figure 5 As shown, the mounting base 100 includes a mounting shaft 110 and a first side plate 120 and a second side plate 130 that are oppositely and spaced apart, and the first side plate 120 and the second side plate 130 are fixedly penetrated through the mounting shaft 110. A driving source is arranged on the side of the first side plate 120 that is away from the second side plate 130, the output member 200 is rotated and penetrated through the mounting shaft 110, and is located on the side of the second side plate 130 that is away from the first side plate 120, and the first stopper 300 and the second stopper 400 are hinged to the side of the second side plate 130 that is away from the first side plate 120, and the first energy storage member 800 and the second energy storage member 900 are arranged in the clamping cavity between the first side plate 120 and the second side plate 130, and the various components are arranged reasonably to improve the utilization rate of the space and reduce the size of the entire operating mechanism. It should be noted that a first slide groove 121 corresponding to the movement trajectory of the first driving member 600 and a second slide groove 122 corresponding to the movement trajectory of the second driving member 700 should be opened on the first side plate 120 and the second side plate 130, and the first driving member 600 is slidably set in the first slide groove 121, and the second driving member 700 is slidably set in the second slide groove 122 to provide movement space for the first driving member 600 and the second driving member 700.

[0056] Specific working process: Figure 6 As shown, the output member 200 is located at the normal closing position, at which time, the protrusion 230 is released from the abutment with the first limiting protrusion 311 and the second limiting protrusion 411. Correspondingly, the switch body controlled by the operating mechanism is connected to the normal power supply.

[0057] When the output member 200 needs to be switched from the normal closing position to the double opening position, that is, when the normal power supply is disconnected, the first driving member 600 is driven by an external force to rotate counterclockwise along the first arc-shaped groove 210 in the direction of the arrow. During this process, the first energy storage member 800 starts to store energy, and the first driving member 600 is always in contact with the first triggering portion 320, so that the first limiting portion 310 connected to the first triggering portion 320 is away from the output member 200, thereby causing the reset member 500 connected to the first limiting portion 310 to deform and store energy; Figure 7 As shown in FIG. 1 , when the first driving member 600 slides from one end of the first arc-shaped groove 210 to the other end, the first energy storage member 800 also reaches the dead point position. After the external force is removed, the first energy storage member 800 starts to release energy and drives the first driving member 600 to continue to rotate counterclockwise around the arrow direction. During this process, the first driving member 600 drives the first arc-shaped groove 210 to rotate counterclockwise around the arrow direction, and the first driving member 600 is separated from the first triggering part 320, and the reset member 500 drives the first limiting part 310 to move toward the direction close to the output member 200; Figure 8 As shown, when the output member 200 is driven by the first driving member 600 to rotate to the double-split position, the first energy storage member 800 completely releases energy, the first driving member 600 is not driven by external force, and no longer drives the output member 200 to move, and the first limiting portion 310 moves to abut against the output member 200 under the drive of the reset member 500, and the reset member 500 also returns to the initial state and no longer drives the first limiting portion 310 to continue moving. It should be understood that when the first driving member 600 drives the first stop member 300 to move, the second driving member 700 should always remain at the double-open position of the output member 200 and not move, and the second stop member 400 should also always remain at a position close to the output member 200 and not move, so that when the output member 200 rotates to the double-open position, the second limit portion 410 also abuts against the output member 200. Thus, the first limit portion 310 and the second limit portion 410 respectively abut against the opposite sides of the output member 200, so that the output member 200 can be reliably stopped at the double-open position. When it is necessary to connect to the normal power supply, it is only necessary to reversely drive the first driving member 600 to drive the output member 200 from the double-open position back to the normal closing position, that is, Figure 8 The dual position Figure 7 Back to Figure 6 Common closing positions.

[0058] When the output member 200 needs to be switched from the double-open position to the standby closing position, that is, when the standby power supply is turned on, the second driving member 700 is driven by an external force to rotate counterclockwise along the second arc groove 220 in the direction of the arrow. During this process, the movement of the second driving member 700 drives the second energy storage member 900 to start storing energy. At the same time, the second driving member 700 and the second triggering portion 420 are switched from a separated state to an abutted state. Therefore, the rotation of the second driving member 700 drives the second limiting portion 410 to move in a direction away from the output member 200, so that the second limiting portion 410 is released from the abutment with the output member 200, and the reset member 500 connected to the second limiting portion 410 is deformed to store energy. At this time, the sliding of the second driving member 700 in the second arc groove 220 will not drive the rotation of the second arc groove 220, that is, the output member 200 remains stationary. Fig. 9 As shown in FIG. 1 , when the second driving member 700 slides from one end of the second arc-shaped groove 220 to the other end, the second energy storage member 900 also reaches the dead point position. At this time, the second energy storage member 900 starts to release energy and drives the second driving member 700 to continue to rotate counterclockwise around the arrow direction, thereby driving the second arc-shaped groove 220 to rotate counterclockwise around the arrow direction. At the same time, the second driving member 700 is always in contact with the second triggering portion 420, and also drives the second limiting portion 410 to overcome the pulling force of the reset member 500 and continue to move in the direction away from the output member 200; Fig.10 As shown, when the output member 200 is driven by the second drive member 700 to rotate to the standby closing position, the second energy storage member 900 completely releases energy, and the second drive member 700 is not driven by external force, and no longer drives the output member 200 to move, and the output member 200 stops at the standby closing position. It should be understood that when the second drive member 700 drives the second stop member 400 to move, the first drive member 600 should always remain at the double-open position of the output member 200 and not move, and the first stop member 300 should also always remain at a position close to the output member 200 and not move. However, when the output member 200 rotates to the standby closing position, the position of its protrusion 230 changes, so the first limit protrusion 311 of the first limit part 310 also releases the contact with the protrusion 230 of the output member 200. When the standby power supply needs to be disconnected, it is only necessary to reversely drive the second drive member 700 to drive the output member 200 from the standby closing position back to the double-open position, that is, Fig.10 The backup closing position is Fig. 9 Back to Figure 8 The double position.

[0059] In other embodiments, when the output member 200 needs to be switched from the double-open position to the standby closing position, that is, when the standby power supply is turned on, the second driving member 700 is driven by an external force to rotate counterclockwise along the second arc-shaped groove 220 in the direction of the arrow. During this process, the movement of the second driving member 700 drives the second energy storage member 900 to start storing energy, and because the second driving member 700 and the second triggering portion 420 are in a separated state, the rotation of the second driving member 700 will not drive the movement of the second limiting portion 410. At the same time, the sliding of the second driving member 700 in the second arc-shaped groove 220 will not drive the rotation of the second arc-shaped groove 220, that is, the second stopper 400 and the output member 200 remain stationary; Fig. 9 As shown in the figure, when the second driving member 700 slides from one end of the second arc-shaped groove 220 to the other end, the second energy storage member 900 also reaches the dead point position. At this time, the second energy storage member 900 starts to release energy and drives the second driving member 700 to continue to rotate counterclockwise around the arrow direction. During this process, the second driving member 700 abuts against the second triggering part 420, and drives the second limiting part 410 to overcome the pulling force of the reset member 500 and move in the direction away from the output member 200, so that the second limiting part 410 is released from the abutment with the output member 200, and then the second driving member 700 can drive the second arc-shaped groove 220 to rotate counterclockwise around the arrow direction under the action of the second energy storage member 900; as shown in the figure, Fig.10 As shown, when the output member 200 is driven by the second drive member 700 to rotate to the standby closing position, the second energy storage member 900 completely releases energy, and the second drive member 700 is not driven by external force, and no longer drives the output member 200 to move, and the output member 200 stops at the standby closing position. It should be understood that when the second drive member 700 drives the second stop member 400 to move, the first drive member 600 should always remain at the double-open position of the output member 200 and not move, and the first stop member 300 should also always remain at a position close to the output member 200 and not move. However, when the output member 200 rotates to the standby closing position, the position of its protrusion 230 changes, so the first limit protrusion 311 of the first limit part 310 also releases the contact with the protrusion 230 of the output member 200. When it is necessary to disconnect the standby power supply, it is only necessary to reversely drive the second drive member 700 to drive the output member 200 from the standby closing position back to the double-open position, that is, Fig.10 The backup closing position is Fig. 9 Back to Figure 8 The double position.

[0060] In general, when the first driving member 600 and the second driving member 700 move, they can be used to release the position limit of the output member 200 by the first stop member 300 and the second stop member 400, and can also be used to drive the first energy storage member 800 and the second energy storage member 900 to store energy, and can also drive the output member 200 to switch states. The first driving member 600 and the second driving member 700 can drive the first energy storage member 800 and the second energy storage member 900 to store energy while driving multiple parts to move, which reduces the number of parts used in this product and facilitates assembly.

[0061] The embodiment of the present application provides a transfer switch, including a switch body and any of the above-mentioned operating mechanisms, wherein the output member 200 of the operating mechanism cooperates with the moving contact of the switch body so that the external force acting on the output member 200 is accurately transmitted to the moving contact, thereby, when the output member 200 is in the double-open position, the moving contact is also in the double-open position, that is, at this time, the moving contact is neither in contact with the static contact on the common side nor in contact with the static contact on the standby side, thereby realizing the double disconnection of the transfer switch from the common power supply and the standby power supply. When the output member 200 is in the common closing position, the moving contact is driven to contact with the static contact on the common side, thereby realizing the connection of the common power supply. When the output member 200 is in the standby closing position, the moving contact is driven to contact with the static contact on the standby side, thereby realizing the connection of the standby power supply.

[0062] Optionally, the transfer switch further includes a controller, which can receive terminal signals and control the operating mechanism to drive the switch body to switch between the double open position, the common closing position and the standby closing position according to the terminal signals, thereby realizing electric operation. Of course, a handle can also be matched to realize manual operation, that is, the operating mechanism is driven by the handle to drive the switch body to switch between the double open position, the common closing position and the standby closing position. In addition, the controller can also be used to detect power quality and equipment status.
