Description

Technical Field

[0001] This application relates to the field of switch technology, and more specifically, to an automatic transfer switch and control circuit. Background Technology

[0002] An automatic transfer switch (ATS) is an intelligent switching device used in power systems that enables load circuits to switch between different power sources, thereby ensuring continuous power supply to critical loads.

[0003] In existing technologies, automatic transfer switches have a wide range of applications, and the specific functional requirements for them vary across different scenarios. In some scenarios, space constraints limit the size of the automatic transfer switch, requiring it to be compact for easy installation and use. In other scenarios, higher control precision is required, necessitating real-time monitoring of the switch's operating position for timely adjustment or indication. This necessitates a switch position feedback structure, but the addition of this structure inevitably increases the switch's size.

[0004] As can be seen from the above, due to the different requirements for the use of automatic transfer switches in the existing technology, it is difficult for automatic transfer switches to meet the above requirements at the same time. Therefore, different automatic transfer switch structures need to be designed for different use scenarios, which increases the design and production costs of automatic transfer switches.

[0005] Therefore, there is an urgent need to provide an automatic transfer switch structure that can meet different usage requirements of automatic transfer switches while reducing the production and processing costs of automatic transfer switches. Utility Model Content

[0006] The purpose of this application is to provide an automatic transfer switch that can meet different usage requirements of the automatic transfer switch while reducing the production and processing costs of the automatic transfer switch.

[0007] To achieve the above objectives, in a first aspect, this application provides an automatic transfer switch for switching a load between different power sources. The automatic transfer switch includes a switch module and a feedback module. The switch module includes a first housing and a rotating shaft, the rotating shaft being rotatably disposed within the first housing. The first housing has a first contact surface, the end of the rotating shaft protruding from the first contact surface, and a groove provided on the end of the rotating shaft. The feedback module includes a second housing and a linkage member, the linkage member being rotatably disposed within the second housing. The second housing has a second contact surface, the end of the linkage member protruding from the second contact surface, and a protrusion provided on the end of the linkage member, the protrusion being able to insert into the groove. When the rotating shaft rotates, it can drive the load to switch between different power sources. When the protrusion is inserted into the groove, the rotating shaft can drive the linkage member to rotate, and the rotation of the linkage member can provide feedback on the operating position of the switch module.

[0008] Based on the embodiments described above, when the automatic transfer switch is in use, the switch module is formed as a separate module within the first housing, and the feedback module is also formed as a separate module within the second housing. In specific applications, when there are significant size constraints on the automatic transfer switch and displaying the real-time operating position of the switch module is not required, the switch module can be used independently to achieve load switching between different power sources. However, when real-time display of the switch module's operating position is more important when using the automatic transfer switch, the switch module and feedback module can be assembled together. The switch module achieves load switching between different power sources, and the feedback module displays the switch module's operating position in real time.

[0009] Furthermore, enclosed by the first and second housings, the switching module and feedback module each form an independent modular structure. Through the interaction of grooves and protrusions, they can be quickly assembled to expand the functionality of the feedback signal. Simultaneously, their independent modular design allows for electrical isolation between the feedback module and the switching module, facilitating convenient and rapid expansion while improving the reliability and safety of the switching module when used independently.

[0010] During the specific connection, the first mating surface and the second mating surface are mated together, and the protrusion is inserted into the groove. When the automatic changeover switch is working, the rotating shaft rotates accordingly, and then the linkage is driven to rotate through the cooperation of the protrusion and the groove, thereby driving the feedback module. Thus, the feedback module provides real-time feedback on the working position of the switch module.

[0011] In summary, this application modularizes the switch module and feedback module separately, allowing for quick connection or disassembly as needed. This enables the automatic transfer switch to meet diverse usage requirements while avoiding increased production costs due to differentiated design and manufacturing. Furthermore, the feedback module and switch module are connected via a bump-and-groove connection, facilitating rapid connection and drive between the two modules.

[0012] In some embodiments, one of the first mating surface and the second mating surface is provided with a insertion groove, and the other is provided with a plug-in member, which can be inserted into the insertion groove.

[0013] Based on the embodiments described above, the connection stability between the switch module and the feedback module is further enhanced through the plug-in engagement of the slot and the connector. Simultaneously, the plug-in method enables both quick connection and quick disassembly when necessary, making the connection and disassembly process simple and convenient overall.

[0014] In some embodiments, at least two insertion slots are provided, and at least two insertion pieces are provided accordingly, with the insertion slots and insertion pieces being inserted into each other.

[0015] Based on the embodiments described above, by increasing the number of plug slots and corresponding connectors, the stability of the connection between the feedback module and the switch module is enhanced. Furthermore, by increasing the number of plug slots and connectors, the relative positions of each plug slot can be configured. For example, when three plug slots and corresponding connectors are provided, the three slots form a triangular structure, making the connection between the switch module and the feedback module more stable, thereby further strengthening the connection effect.

[0016] In some embodiments, the groove is configured as a regular polygon structure, and the corresponding protrusion is configured as a regular polygon structure.

[0017] Based on the embodiments described above, by setting the groove to a regular polygonal structure, such as an equilateral triangle, a square, or a regular pentagon, the protrusion is also set to a corresponding shape. This ensures stable driving between the rotating shaft and the linkage, while also facilitating insertion and fixing, making the assembly process simple and quick.

[0018] In some embodiments, a swing block is provided on the side of the linkage member, and the feedback module further includes a first micro switch and a second micro switch, which are spaced apart on the side of the linkage member along the rotation direction of the linkage member. The first micro switch includes a first lever, and the second micro switch includes a second lever. When the linkage member rotates, the swing block can sequentially abut against one of the first lever and the second lever.

[0019] Based on the above embodiments of this application, a specific structure of the feedback module is disclosed. When the linkage rotates under the cooperative drive of the protrusion and groove, the swing block moves with the linkage to different positions and can respectively abut against the first and second levers. When the swing block abuts against the first lever, the first micro switch and its connected feedback circuit are in a conducting state, while the second lever, the second micro switch, and their corresponding feedback circuits are in a de-energized state, thereby displaying one working position of the switch module. Conversely, when the swing block rotates with the linkage to another position and abuts against the second lever, the feedback circuit corresponding to the second micro switch is turned on while the feedback circuit corresponding to the first micro switch is turned off, thereby displaying another working position of the switch module. This achieves feedback and differentiation of different working positions of the switch module.

[0020] In some embodiments, the first paddle includes a first fixed end and a first contact end, the first fixed end being connected to the first contact end and fixed to the second housing, and the first contact end being configured as a raised arcuate structure with the raised direction facing the linkage member. The second paddle includes a second fixed end and a second contact end, the second fixed end being connected to the second contact end and fixed to the second housing, and the second contact end being configured as a raised arcuate structure with the raised direction facing the linkage member. A third contact end is provided at the end of the swing block opposite to the linkage member, the third contact end being configured as a raised arcuate structure, and when the linkage member rotates, the third contact end can abut against the first contact end and the second contact end respectively.

[0021] Based on the embodiments described above, a specific structural shape of the first and second paddles is disclosed. Taking the first paddle as an example, the first fixed end is used to fix the overall position of the first paddle, while the first contact end is used for direct contact with the swing block. Furthermore, by providing the arc-shaped surface structure on the first contact end and the arc-shaped protrusion structure on the third contact end of the swing block, the entire process from initial contact to separation between the first and third contact ends is smoother, avoiding problems such as jamming between the swing block and the first paddle that could affect the normal operation of the feedback module. Similarly, by providing the above-described structure for the second paddle, the contact and separation process between the second paddle and the swing block is smoother.

[0022] In some embodiments, the feedback module further includes a wiring port, which is fixed to the second housing, and the first and second levers are electrically connected to the wiring port, respectively.

[0023] Based on the above embodiments of this application, by setting a wiring port for external display of the feedback module, the setting of the wiring port can also make the external connection process of the feedback module simpler and faster.

[0024] In some embodiments, the contour of the switch module along the first direction is the same as the contour of the feedback module along the first direction, and the first direction corresponds to the axial direction of the rotating shaft.

[0025] Based on the above embodiments of this application, by setting the switch module and the feedback module to have the same outline in the first direction, and the first direction corresponds to the axis direction of the rotating shaft, that is, the assembly direction between the feedback module and the switch module, the overall shape of the automatic transfer switch after assembly is more regular, which facilitates installation and use while reducing the overall size of the automatic transfer switch.

[0026] According to a second aspect of this application, a control circuit is provided, the control circuit including a first power supply and a second power supply and the aforementioned automatic transfer switch, the automatic transfer switch being capable of switching the load between the first power supply and the second power supply.

[0027] Based on the embodiments described above, the control circuit provided in this application includes the aforementioned automatic transfer switch, which enables the load to switch between a first power supply and a second power supply. Furthermore, the automatic transfer switch configuration in this application allows it to meet various usage requirements. When space constraints significantly limit the size of the automatic transfer switch, the switch module can be used independently to achieve load switching. When the control circuit prioritizes real-time feedback on the switch module's operating position, a feedback module can be quickly connected to the switch module via a plug-in connection to drive it, providing real-time feedback on the switch module's operating position.

[0028] In summary, the above-described configuration of the automatic transfer switch in this application enables the control circuit to select different automatic transfer switch structures as needed, and allows for rapid switching between two different structures, thereby reducing overall costs while meeting different usage requirements.

[0029] In some embodiments, when the automatic transfer switch switches the load to the first power source, the swashplate abuts against the first lever. When the automatic transfer switch switches the load to the second power source, the swashplate abuts against the second lever.

[0030] Based on the above embodiments of this application, the swing block is connected to different power supplies connected to different control circuits corresponding to different levers, that is, different working positions of the switching module, thereby realizing real-time feedback on the working position of the switching module.

[0044] Automatic transfer switches (ATS) are intelligent switching devices commonly used in power systems. They enable load circuits to switch between different power sources. They are typically used to switch load circuits to backup power sources when the main power supply fails, ensuring continuous power supply to critical loads.

[0045] In existing technologies, due to the wide range of applications of automatic transfer switches, the specific functional requirements for them vary. In some scenarios, space constraints limit the size of the automatic transfer switch, requiring it to be confined to a small area for installation and use. In other scenarios, higher control precision is required, necessitating real-time monitoring of the switch's operating position for timely adjustment or indication. In such cases, the automatic transfer switch needs a switch position feedback structure, but this inevitably increases its size.

[0046] As can be seen from the above, due to the different requirements for the use of automatic transfer switches in the existing technology, it is difficult for automatic transfer switches to meet the above requirements at the same time. Therefore, different automatic transfer switch structures need to be designed for different use scenarios, which increases the design and production costs of automatic transfer switches.

[0047] Therefore, there is an urgent need to provide an automatic transfer switch structure that can meet different usage requirements of automatic transfer switches while reducing the production and processing costs of automatic transfer switches.

[0048] To address the aforementioned problems in the prior art, embodiments of this application provide an automatic transfer switch for switching loads between different power sources. (Reference) Figure 1 and Figure 2 As shown, the automatic transfer switch includes a switch module 1 and a feedback module 2. The switch module 1 includes a first housing 11 and a rotating shaft 12. The rotating shaft 12 is rotatably disposed within the first housing 11. The first housing 11 has a first contact surface 13, and the end of the rotating shaft 12 protrudes from the first contact surface 13. A groove 14 is provided on the end of the rotating shaft 12. The feedback module 2 includes a second housing 21 and a linkage 22. The linkage 22 is rotatably disposed within the second housing 21. The second housing 21 has a second contact surface 23, and the end of the linkage 22 protrudes from the second contact surface 23. A protrusion 24 is provided on the end of the linkage 22, which can be inserted into the groove 14. The rotating shaft 12 can rotate as the load switches between different power sources. When the protrusion 24 is inserted into the groove 14, the rotating shaft 12 can drive the linkage 22 to rotate, and the rotation of the linkage 22 can provide feedback on the working position of the switch module 1.

[0049] Based on the above embodiments of this application, when the automatic transfer switch is used, the switch module 1 forms a separate module under the enclosure of the first housing 11, and the feedback module 2 also forms a separate module under the enclosure of the second housing 21. In specific use, when the size of the automatic transfer switch is limited and the real-time operating position of the switch module 1 is not required, the switch module 1 can be used alone to achieve load switching between different power sources. However, when the real-time display of the operating position of the switch module 1 is more important when using the automatic transfer switch, the switch module 1 and the feedback module 2 can be assembled together. The switch module 1 achieves load switching between different power sources, and the feedback module 2 displays the real-time operating position of the switch module 1.

[0050] Furthermore, enclosed by the first housing 11 and the second housing 21, the switch module 1 and the feedback module 2 each form an independent modular structure. The feedback signal functionality can be quickly expanded through assembly via the cooperation of the groove 14 and the protrusion 24. Simultaneously, their independent modular design allows for electrical isolation between the feedback module 2 and the switch module 1, making the expansion process convenient and quick, and improving the reliability and safety of the switch module 1 when used alone.

[0051] In the specific connection, the first mating surface 13 and the second mating surface 23 are mated together, and the protrusion 24 is inserted into the groove 14. When the automatic changeover switch is working, the rotating shaft 12 rotates accordingly, and then the linkage 22 is driven to rotate through the cooperation of the protrusion 24 and the groove 14, thereby driving the feedback module 2 and realizing real-time feedback on the working position of the switch module 1 through the feedback module 2.

[0052] In summary, this application modularizes the switch module 1 and feedback module 2 separately, allowing for quick connection or disassembly as needed. This enables the automatic transfer switch to meet diverse usage requirements while avoiding increased production costs due to differentiated design and manufacturing. Furthermore, the feedback module 2 and switch module 1 are connected via the insertion of protrusion 24 and groove 14, enabling rapid connection and drive between the two modules.

[0053] Furthermore, it should be noted that the modular design of the switch module 1 and feedback module 2 in this application allows for the selection of whether or not to assemble the feedback module 2 as needed. The feedback module 2 can output different feedback signals according to different working positions of the switch module 1. Simultaneously, the connection and drive between the switch module 1 and the feedback module 2 are both achieved through plug-in connections, making the connection and disassembly process simple and quick.

[0054] This application does not impose specific restrictions on the specific structure and working principle of the switch module 1. While satisfying the above limitations, the switch module 1 can be configured with any suitable structure. For example, in some embodiments of this application, in addition to the first housing 11 and the rotating shaft 12 described above, the switch module 1 may also include a drive motor and an energy storage component. Different contact structures are arranged in the circumferential direction of the rotating shaft 12, and these different contact structures are connected to different power sources. The drive motor is used to drive the rotating shaft 12 to rotate within a certain angle, and one of the power sources, such as the main power supply, can be connected to the drive motor to supply power. The energy storage component can be configured as a torsion spring or similar structure, and the rotating shaft 12 can compress the torsion spring to store energy when rotating with the drive motor.

[0055] When switch module 1 is operating, if the main power supply is working normally, the load is connected to the main power supply, and the main power supply continuously supplies power to the drive motor, causing the rotating shaft 12 to rotate at a certain angle. At this time, the rotating shaft 12 rotates to the contact position corresponding to the main power supply, realizing the conduction of the main power supply. When the main power supply experiences an abnormal power outage, the drive motor loses power and stops working. Subsequently, the torsion spring releases and drives the rotating shaft 12 to reset, causing the rotating shaft 12 to rotate to the position of the contact corresponding to another power supply, such as the backup power supply, realizing the conduction of the backup power supply. When the main power supply is restored, it can continue to drive the drive motor, thereby driving the rotating shaft 12 to rotate and switch to the power supply line of the main power supply.

[0056] It should be noted that the "working position of switch module 1" mentioned above in this application refers to the different rotation angles of the rotating shaft 12 when the switch module 1 is switching. When the automatic transfer switch is working, the rotation of the rotating shaft 12 drives the load to switch between different power sources. At this time, the different rotation angles of the rotating shaft 12 correspond to the connection states of different power sources.

[0057] The above provides a specific structure and working principle of switch module 1. In actual use, while meeting the usage requirements of the aforementioned rotating shaft 12 and other structures, switch module 1 can be designed with any suitable structure according to different working principles. Since this application does not involve improvements to the specific structure of switch module 1, further details are omitted here.

[0058] Similarly, feedback module 2 can also be configured with any suitable structure in this application. (See reference) Figures 3 to 5 As shown in the exemplary embodiment provided in this application, a swing block 6 is provided on the side of the linkage 22, and the feedback module 2 may further include a first micro switch and a second micro switch. The first micro switch and the second micro switch are distributed at intervals on the side of the linkage 22 along the rotation direction of the linkage 22. The first micro switch includes a first lever 4, and the second micro switch includes a second lever 5. When the linkage 22 rotates, the swing block 6 can sequentially abut against one of the first lever 4 and the second lever 5.

[0059] Based on the above embodiments of this application, a specific structure of the feedback module 2 is disclosed. When the linkage 22 rotates under the cooperative drive of the protrusion 24 and the groove 14, the swing block 6 moves with the linkage 22 to different positions and can respectively abut against the first lever 4 and the second lever 5. When the swing block 6 abuts against the first lever 4, the first micro switch and its connected feedback circuit are in a conducting state, while the second lever 5, the second micro switch, and their corresponding feedback circuits are in a de-energized state, thereby displaying one working position of the switch module 1. Conversely, when the swing block 6 rotates with the linkage 22 to another position and abuts against the second lever 5, the feedback circuit corresponding to the second micro switch is turned on while the feedback circuit corresponding to the first micro switch is turned off, thereby providing feedback on another working position of the switch module 1. This achieves feedback and differentiation of different working positions of the switch module 1.

[0060] It should be noted that in this application, the first micro switch and the second micro switch are used to correspond to the two different working positions of the switch module 1. In actual use, the switch module 1 can also be set with multiple working positions. In this case, the number of paddles can be increased accordingly. Multiple paddles are arranged on the outer periphery of the linkage 22 along the rotation direction of the linkage 22, and the swing block 6 can abut against any one of the multiple paddles when it rotates with the linkage 22, thereby using multiple paddles to correspond to the multiple working positions of the switch module 1.

[0061] During actual assembly, the swing block 6, the first lever 4, and the second lever 5 are each connected to a wire structure. When the swing block 6 abuts against the first lever 4, a conductive structure is formed from the swing block 6 to the first lever 4. When the swing block 6 abuts against the second lever 5, a conductive structure is formed from the swing block 6 to the second lever 5. This provides feedback and displays the different working positions of the switch module 1.

[0062] In summary, this application uses a first micro switch, a second micro switch, and a swing block 6 as the triggering structure for the feedback module 2. Specifically, taking the triggering process of the first micro switch as an example, as the swing block 6 rotates with the linkage 22, it moves closer to the first micro switch until it begins to contact the first lever 4. Subsequently, as the contact between the swing block 6 and the first lever 4 increases, the force exerted by the swing block 6 on the first lever 4 also gradually increases until a critical state is reached. The first micro switch is then quickly triggered and switches the conduction state of the corresponding feedback circuit, making the corresponding feedback circuit conduct and realizing the feedback display of the working position of the switch module 1. When the swing block 6 resets and disengages from the first lever 4, the first micro switch is triggered again, causing the corresponding feedback circuit to disconnect.

[0063] The present application discloses a specific triggering structure and triggering method for the feedback module 2. In actual use, the feedback module 2 can also select any other suitable triggering structure to cooperate with the linkage 22 to realize feedback triggering.

[0064] Furthermore, based on the aforementioned usage scenarios, the first lever 4 and the second lever 5 need to meet good electrical conductivity requirements during use, while also possessing a certain strength. In specific applications, the first lever 4 and the second lever 5 can be made of pure copper, various copper alloys, or other suitable metal materials.

[0065] Meanwhile, a swing block 6 is provided on the linkage 22 to abut against the first lever 4 and the second lever 5. Therefore, the swing block 6 also needs to meet good conductivity and certain strength requirements. The specific material can be selected with reference to the first lever 4 and the second lever 5. In the actual production and processing, the swing block 6 and the linkage 22 can be set as one piece. By setting the two as one piece, it is not only convenient for production and processing, but also improves the connection strength between the two.

[0066] Further reference Figures 3 to 5 As can be seen, in some embodiments of this application, the first paddle 4 may include a first fixed end 41 and a first contact end 42. The first fixed end 41 is connected to the first contact end 42 and is fixed to the second housing 21. The first contact end 42 is configured as a raised arc-shaped structure, with the raised direction facing the linkage member 22. The second paddle 5 may include a second fixed end 51 and a second contact end 52. The second fixed end 51 is connected to the second contact end 52 and is fixed to the second housing 21. The second contact end 52 is configured as a raised arc-shaped structure, with the raised direction facing the linkage member 22. The swing block 6 has a third contact end 61 at one end away from the linkage member 22. The third contact end 61 is configured as a raised arc-shaped structure, and when the linkage member 22 rotates, the third contact end 61 can abut against the first contact end 42 and the second contact end 52 respectively.

[0067] Based on the embodiments described above, a specific structural shape of the first paddle 4 and the second paddle 5 is disclosed. Taking the first paddle 4 as an example, the first fixed end 41 is used to fix the overall position of the first paddle 4, while the first contact end 42 is used for direct contact with the swing block 6. Furthermore, through the arc-shaped surface structure on the first contact end 42 and the arc-shaped protrusion structure on the third contact end 61 of the swing block 6, the entire process from the initial contact to the separation of the first contact end 42 and the third contact end 61 is made smoother, avoiding problems such as jamming between the swing block 6 and the first paddle 4 that would affect the normal operation of the feedback module 2. Similarly, through the above-described configuration of the structure of the second paddle 5, the contact and separation process between the second paddle 5 and the swing block 6 is made smoother.

[0068] It should be noted that the phrase "the first fixed end 41 is fixed to the second housing 21" in this application refers to the first fixed end 41 being connected to the second housing 21 directly or indirectly to fix the position of the first lever 4 relative to the second housing 21. In actual assembly, the first lever 4 and the first fixed end 41, as part of the first micro switch, can be fixed to the second housing 21 together with the first micro switch. Various connection methods, including bolt fixing and adhesive bonding, can be used, and this application does not impose specific limitations on this. Similarly, the phrase "the second fixed end 51 is fixed to the second housing 21" also refers to the second fixed end 51 being connected to the second housing 21 directly or indirectly; the specific connection method can be referenced from the first lever 4.

[0069] Specifically, when selecting materials for the first lever 4 and the second lever 5, in addition to the aforementioned requirements for conductivity and strength, they should also possess a certain degree of elasticity. This elasticity ensures that when the pendulum 6 moves to the position of the first lever 4, the first lever 4 is compressed and undergoes a certain bending deformation. Simultaneously, the elasticity of the first lever 4 allows the first contact end 42 to stably abut against the third contact end 61. Subsequently, after the pendulum 6 resets, the first lever 4 naturally rebounds. The second lever 5 behaves similarly to the first lever 4. In summary, by ensuring a certain degree of elasticity, the first lever 4 and the second lever 5 neither affect the rotation of the pendulum 6 nor fail to maintain stable contact with the third contact end 61 at the end of the pendulum 6 under their own elasticity, thus improving the reliability of the feedback module 2 during operation.

[0070] refer to Figure 2 and Figure 3 As shown in some embodiments of this application, the feedback module 2 may further include a wiring port 7, which is fixed to the second housing 21, and the first lever 4 and the second lever 5 are electrically connected to the wiring port 7 respectively.

[0071] Based on the above embodiments of this application, by setting the wiring port 7 for the external display of the feedback module 2, the external connection process of the feedback module 2 can be made simpler and faster. Specifically, the external display can be any suitable display structure. For example, in some embodiments of this application, the external display may include a processor and indicator lights. The processor receives feedback signals from the first feedback switch and the second feedback switch, and then controls the corresponding indicator lights to turn on or off to intuitively display the working position of the switch module 1.

[0072] In addition, in some other technical solutions of this application, a PCB circuit board or similar structure can be directly installed inside the second housing 21, and the PCB circuit board can be connected to the first lever 4, the second lever 5, and the swing block 6 for signal reception and processing. Simultaneously, an indicator light or display screen can be installed on the second housing 21 for direct display of the working position of the switch module 1. The specific configuration can be adjusted according to actual conditions, and this application does not impose specific limitations on this.

[0073] refer to Figure 1 and Figure 2 As shown in some embodiments of this application, the contour of the switch module 1 along the first direction may be the same as the contour of the feedback module 2 along the first direction, wherein the first direction corresponds to the axial direction of the rotating shaft 12.

[0074] Based on the above embodiments of this application, by setting the switch module 1 and the feedback module 2 to have the same outline in the first direction, and the first direction corresponds to the axis direction of the rotating shaft 12, that is, the assembly direction between the feedback module 2 and the switch module 1, the overall shape of the automatic transfer switch after assembly is more regular, which facilitates installation and use while reducing the overall size of the automatic transfer switch.

[0075] In this application, in order to improve the connection strength and stability between the switch module 1 and the feedback module 2, [reference needed]. Figure 1 and Figure 2 As shown, in some embodiments, one of the first mating surface 13 and the second mating surface 23 may be provided with a insertion groove 3, and the other may be provided with a connector 31, which can be inserted into the insertion groove 3.

[0076] Based on the embodiments described above, the connection stability between the switch module 1 and the feedback module 2 is further enhanced through the insertion and engagement of the insertion slot 3 and the insertion piece 31. Simultaneously, the insertion method enables both quick connection and quick disassembly when necessary, making the connection and disassembly process simple and convenient overall.

[0077] Specifically, the connector 31 can be configured as a circular cylindrical structure, and the corresponding connector slot 3 can be configured as a circular cavity structure. During fixing, the connector 31 is inserted into the connector slot 3, and the feedback module 2 and the switch module 1 are fixed by a tight fit.

[0078] Furthermore, in actual use, the insertion slot 3 can be provided on either the first mating surface 13 or the second mating surface 23, in which case the other of the first mating surface 13 or the second mating surface 23 is provided with a corresponding insertion member 31. Alternatively, in some embodiments, the first mating surface 13 can be provided with both the insertion slot 3 and the insertion member 31, and the second mating surface 23 is provided with a corresponding insertion member 31 according to the first mating surface 13.

[0079] However, since the switch module 1 can be used independently, considering the ease of assembly when the switch module 1 is used independently, and to avoid the protruding structure affecting the space occupied by the switch module 1 and the assembly process, in the actual production process, the plug slot 3 can be set on the first mating surface 13 as much as possible, while the plug 31 can be set on the second mating surface 23.

[0080] Furthermore, in some embodiments of this application, at least two insertion slots 3 may be provided, and at least two insertion pieces 31 may be provided accordingly, with the insertion slots 3 and insertion pieces 31 being inserted into each other.

[0081] Based on the embodiments described above, by increasing the number of plug slots 3 and corresponding connectors 31, the stability of the connection between the feedback module 2 and the switch module 1 is enhanced. Simultaneously, by increasing the number of plug slots 3 and connectors 31, the relative positions of each plug slot 3 can be set. For example, when three plug slots 3 and a corresponding number of connectors 31 are provided, the three plug slots 3 form a triangular structure, making the connection between the switch module 1 and the feedback module 2 more stable, thereby further enhancing the connection effect.

[0082] The specific number of connectors 31 and corresponding connector slots 3 can be set according to the area and shape of the first mating surface 13 and the second mating surface 23. For example, when both the first mating surface 13 and the second mating surface 23 are set as rectangular structures, connector slots 3 can be set at the four corners of the first mating surface 13, and connectors 31 can be set at the corresponding positions on the second mating surface 23. When the area of ​​the first mating surface 13 and the second mating surface 23 is large, the number of connector slots 3 and corresponding connectors 31 can be further increased. For example, in addition to the four corners, connector slots 3 and connectors 31 can be set at positions close to the midpoints of the four sides of the rectangle. The specific settings can be made according to the actual situation, and this application does not impose specific limitations on this.

[0083] In this application, the linkage between the rotating shaft 12 and the linkage component 22 is achieved through the cooperation of the groove 14 and the protrusion 24. In practical use, the cross-sectional shape of the groove 14 and the protrusion 24 can be set to any suitable shape.

[0084] refer to Figure 1 and Figure 2 As shown in the example provided in this application, the groove 14 can be configured as a regular polygon structure, and the protrusion 24 can be configured as a regular polygon structure accordingly.

[0085] Based on the embodiments described above, by setting the groove 14 as a regular polygonal structure, such as an equilateral triangle, a square, or a regular pentagon, the protrusion 24 is also set to a corresponding shape. This ensures stable driving between the rotating shaft 12 and the linkage 22, while also facilitating insertion and fixing, making the assembly process simple and quick.

[0086] Furthermore, in other embodiments of this application, the cross-sectional shapes of the protrusion 24 and the groove 14 can be set to other shapes. For example, the protrusion 24 can be set to a trapezoidal structure, and the groove 14 can also be set to a trapezoidal structure accordingly. Compared with regular polygonal structures such as squares or regular pentagons, the trapezoidal protrusion 24 and groove 14 can still meet the driving requirements, but there will be problems such as uneven force distribution, and it will be more troublesome to align the protrusion 24 and groove 14 when they are inserted. Alternatively, the protrusion 14 and groove 14 can be set to a T-shape or a cross shape. Compared with regular polygonal structures, in addition to the same problems as trapezoidal structures, the strength of the protrusion 24 itself will be slightly reduced. Alternatively, in other embodiments of this application, the cross-sectional shapes of the protrusion 24 and groove 14 can be set to irregular shapes, such as a combination of circles and triangles. In this case, compared with regular polygonal structures, the protrusion 24 and groove 14 may experience uneven force distribution when they are engaged in driving, which may lead to damage to the protrusion 24 and groove 14. The specific settings can be made according to the actual situation, and this application does not impose specific limitations on them.

[0087] The above-described contents of this application disclose the specific structure of the automatic transfer switch. However, the automatic transfer switch in this application is not limited to the above structure. In specific use, the specific structure of the automatic transfer switch can be adapted to meet the actual usage requirements. For example, in some other embodiments of this application, a torsion spring can also be provided on the linkage 22. When the torsion spring is in the relaxed state, the swing block 6 is located between the first lever 4 and the second lever 5. Subsequently, when the rotating shaft 12 drives the linkage 22 to rotate, the linkage 22 can compress the torsion spring. Through the above settings, the initial positions of the linkage 22 and the swing block 6 can be limited to a relatively fixed position, so that the protrusion 24 and the groove 14 can be quickly inserted when the feedback module 2 is assembled onto the switch module 1.

[0088] Based on the above technical solutions, this application embodiment also provides a control circuit, which includes a first power supply, a second power supply, and the aforementioned automatic transfer switch. The automatic transfer switch can realize the switching of the load between the first power supply and the second power supply.

[0089] Based on the embodiments described above, the control circuit provided in this application includes the aforementioned automatic transfer switch, which enables the load to switch between a first power supply and a second power supply. Furthermore, the automatic transfer switch configuration in this application allows it to meet various usage requirements. When space constraints significantly limit the size of the automatic transfer switch, the switch module 1 can be used alone to achieve load switching. When the control circuit prioritizes real-time feedback on the operating position of the switch module 1, a feedback module 2 can be quickly connected to and driven by the switch module 1 via a plug-in connection, allowing the feedback module 2 to provide real-time feedback on the operating position of the switch module 1.

[0090] In practical applications, automatic transfer switches are typically used to ensure continuous power supply to critical loads. Therefore, the aforementioned primary and secondary power supplies can usually be configured as the main power supply and backup power supply. Under normal circumstances, the main power supply powers the load. When the main power supply fails, the automatic transfer switch switches to the backup power supply to power the load, thus achieving continuous power supply.

[0091] In summary, the above-described configuration of the automatic transfer switch in this application enables the control circuit to select different automatic transfer switch structures as needed, and allows for rapid switching between two different structures, thereby reducing overall costs while meeting different usage requirements.

[0092] In some embodiments of this application, when the automatic transfer switch drives the load to switch to the first power source, the swing block 6 abuts against the first lever 4. When the automatic transfer switch drives the load to switch to the second power source, the swing block 6 abuts against the second lever 5.

[0093] Based on the above embodiments of this application, the swing block 6 is connected to different power supplies connected to different control circuits corresponding to different paddles, that is, different working positions of the switch module 1, thereby realizing real-time feedback on the working position of the switch module 1.

[0094] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0095] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0096] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
