Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0049] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0050] As society develops, people's electricity demand is gradually increasing, which in turn raises the requirements for the power grid and power transmission and distribution. As a result, the application of automatic transfer switches, which can ensure electricity safety, is becoming more and more widespread.

[0051] However, current changeover switches may experience contact or abutment between the drive structure and the control power contact switching structure during the electromagnetic drive reset process when switching power positions. This can cause the switch to vibrate or shake during the reset process, leading to component breakage and failure, which seriously affects the stability and reliability of the product. It may also affect power switching and fail to ensure electrical safety.

[0052] Based on the above problems, this application provides a changeover switch, which is applied in the field of low-voltage electrical technology, and is particularly suitable for products related to dual-power changeover switches.

[0053] Please see Figure 1 The changeover switch 1 provided in this application includes a drive device, which includes a drive mechanism 10. In other words, the changeover switch 1 includes a drive mechanism 10 and an actuator 11. The drive mechanism 10 is connected to the actuator 11, and the drive mechanism 10 drives the actuator 11 to close or open the circuit.

[0054] For details, please refer to Figure 2 and Figure 3The drive mechanism 10 includes a carrier 100, an electromagnetic component 200, a drive member 300, a toggle member 400, an output member 500, and a trajectory member 610. The electromagnetic component 200, the drive member 300, and the toggle member 400 are connected in sequence. The output member 500 and the trajectory member 610 are both movably disposed on the carrier 100. The output member 500 is connected to the actuator 11. Therefore, the electromagnetic component 200 can drive the drive component 300 to move relative to the carrier 100, thereby driving the toggle component 400 to rotate the output component 500. The output component 500 then drives the actuator 11 to rotate between the closed and open positions, thus realizing the switching function of the changeover switch 1. During the reset process of the drive component 300, the track component 610 abuts against the toggle component 400, ensuring that the toggle component 400 and the output component 500 remain separated during the reset process. This prevents the toggle component 400 from contacting or abutting against the output component 500 and causing an impact, thereby avoiding affecting the reset speed and making the reset process smoother. As a result, the structural stability and reliability of the changeover switch 1 are effectively improved, the service life is effectively extended, and electrical safety is ensured.

[0055] Furthermore, the electromagnetic component 200 includes an electromagnetic element 210 and a metal rod 220. The electromagnetic element 210, the metal rod 220, and the driving element 300 are connected in sequence, and the actuating element 400 is disposed at the end of the driving element 300 away from the metal rod 220. Therefore, by driving the metal rod 220 and the driving element 300 to move through the electromagnetic element 210, the actuating element 400 can be moved relative to the carrier 100, thereby actuating the output element 500, thus completing a power state switch. Afterward, the driving element 300 can be reset by moving in the opposite direction under the drive of the electromagnetic component 200, or it can be reset by other components. In this embodiment, a reset spring 110 is also provided on the carrier 100. After the electromagnetic component 200 actuates the output element 500, the driving element 300 is reset by the reset spring 630.

[0056] It should be noted that when the electromagnetic component 200 is not in operation, the toggle member 400 is in the initial position; after the electromagnetic component 200 drives the drive member 300 to move the toggle member 400 to the output member 500 and move to the limit position, the toggle member 400 is in the actuated position. The reset of the toggle member 400 means that the toggle member 400 returns to the initial position from the actuated position under the driving action of the electromagnetic component 200 or the reset spring 110.

[0057] In detail, there are two electromagnetic components 200, two driving components 300, two toggle components 400, and two track components 610, which are symmetrically arranged on both sides of the output component 500 so that the output component 500 can be driven to rotate clockwise or counterclockwise by the track components 610 on both sides.

[0058] Further, please refer to Figure 4 and Figure 6 The trajectory component 610 includes a first contact portion 613 and a second contact portion 614.

[0059] The first contact portion 613 is at least partially located on the moving path of the toggle member 400. The first contact portion 613 is used to contact the toggle member 400 and move the toggle member 400 away from the output member 500 during the reset process.

[0060] It is understandable that the trajectory component 610 essentially changes the movement trajectory of the toggle component 400 during the reset process, thereby abutting against the reset toggle component 400 through the trajectory component 610, thus preventing the toggle component 400 from contacting the output component 500.

[0061] Therefore, it should be noted that in some embodiments of this application, the trajectory member 610 can be fixedly disposed on the carrier 100, and the first contact portion 613 of the trajectory member 610 can allow the actuating member 400 to move in one direction, that is, the actuating member 400 can pass through when it moves from the initial position to the actuated position, and as long as the actuating member 400 moves relative to the carrier 100 under the abutment action of the trajectory member 610 during the reset process, the structure of the trajectory member 610 is not specifically limited here.

[0062] In other embodiments of this application, the trajectory member 610 is movably disposed on the carrier 100, and during the process of the toggle member 400 toggling the output member 500, the toggle member 400 abuts against the trajectory member 610 and drives the trajectory member 610 to move along a direction away from the moving path of the toggle member 400, so that the toggle member 400 can normally toggle the output member 500; when the toggle member 400 resets, the trajectory member 610 can return to the moving path of the toggle member 400 under the action of gravity or the driving action of other driving members 300, and abut against the toggle member 400, so that it always maintains a motion state that prevents interference with the output member 500 to complete the reset.

[0063] Further, the first contact portion 613 includes a first guide surface 6131 and a first holding surface 6132 connected together. The first guide surface 6131 faces the movement path of the toggle member 400 and is away from the reset side of the toggle member 400. The first guide surface 6131 is used to guide the toggle member 400 into the first holding surface 6132. The second contact portion 614 includes a second guide surface 6141 and a second holding surface 6142 connected together. The second guide surface 6141 is located on the movement path of the toggle member 400. The second guide surface 6141 is used to guide the toggle member 400 into the second holding surface 6142. When the toggle member 400 drives the output member 500 to rotate, the second contact portion 614 is used to contact the toggle member 400 and move the trajectory member 610 away from the movement path of the toggle member 400.

[0064] In this embodiment, the first guide surface 6131 and the second guide surface 6141 are arranged in parallel, the first holding surface 6132 and the second holding surface 6142 are arranged in parallel, the first guide surface 6131 and the second guide surface 6141 are both inclined, and the first holding surface 6132 and the second holding surface 6142 are arranged in the same horizontal direction as the movement direction of the toggle member 400. That is, the first guide surface 6131, the second guide surface 6141, the first holding surface 6132 and the second holding surface 6142 together form a parallelogram, which facilitates the toggle member 400 to be guided onto the first holding surface 6132 or the second holding surface 6142. The first holding surface 6132 can keep the toggle member 400 on the movement path that prevents interference with the output member 500.

[0065] It should be noted that in this embodiment, the first guide surface 6131, the second guide surface 6141, the first holding surface 6132, and the second holding surface 6142 are all planar. In other embodiments, they can also be curved surfaces or other structures, as long as they can achieve the above-mentioned effects. No specific limitations are made here.

[0066] For more details, please continue reading. Figures 7 to 9 The drive mechanism 10 also includes a mounting member 620, and a track member 610 is movably disposed on the mounting member 620. The mounting member 620 is mounted on the carrier 100. The mounting member 620 and the track member 610 together constitute a track assembly 600. The track assembly 600 is used to abut against the toggle member 400 during the reset process of the toggle member 400, so as to move the toggle member 400 away from the output member 500.

[0067] Furthermore, the trajectory component 610 includes a sliding body 611 and a slider 612. It should be noted that the first contact portion 613 and the second contact portion 614 are disposed on the slider 612.

[0068] The sliding body 611 and the mounting part 620 are slidably connected. The slider 612 is fixedly disposed on the sliding body 611. At least one side of the slider 612 is provided with a first contact part 613. The first contact part 613 is used to abut against the toggle member 400 during the reset process of the toggle member 400 so that the toggle member 400 is disengaged from the output member 500.

[0069] In this embodiment, it can be understood that during the process of the toggle member 400 toggling the output member 500, the toggle member 400 abuts against the second contact portion 614 of the slider 612 and drives the sliding body 611 to move along a direction away from the moving path of the toggle member 400, so that the toggle member 400 can normally toggle the output member 500; when the toggle member 400 resets, the trajectory member 610 can return to the moving path of the toggle member 400 under the action of gravity or the driving action of other driving members 300, and abut against the toggle member 400, so that it always maintains a motion state that prevents interference with the output member 500 to complete the reset.

[0070] Furthermore, in order to ensure that the sliding body 611 can be reset to the moving path of the toggle member 400 after movement, the trajectory mechanism also includes a reset member 630. The reset member 630 is disposed on the mounting member 620 and acts on the trajectory member 610 to make the trajectory member 610 tend to remain on the reset trajectory of the toggle member 400.

[0071] In this embodiment, the reset member 630 is a spring. One end of the reset member 630 is connected to the mounting member 620, and the other end is connected to the trajectory member 610. It is understood that the spring can be in a stretched state or a compressed state. Thus, the elastic restoring force of the spring acts on the sliding body 611, causing the sliding body 611 to always tend to maintain its position on the movement trajectory of the toggle member 400. It should be noted that the reset member 630 can also be directly mounted on the carrier 100, as long as it ensures that the reset member 630 can perform the above-mentioned function; no specific limitation is made here.

[0072] Furthermore, the mounting component 620 includes a first sliding part 621 and a second sliding part 622. The two sides of the sliding body 611 are provided with slide rails 6111, which can slidably cooperate with the first sliding part 621 and the second sliding part 622, so that the sliding body 611 can move stably on the mounting component 620.

[0073] Furthermore, the mounting component 620 also includes a first limiting part 623 and a second limiting part 624, which are spaced apart. The first sliding part 621, the first limiting part 623, the second sliding part 622, and the second limiting part 624 are sequentially connected and together form a frame structure. The sliding body 611 is slidably disposed between the first limiting part 623 and the second limiting part 624. The first limiting part 623 and the second limiting part 624 are used to limit the sliding stroke of the sliding body 611, so that the sliding body 611 can move in the area between the first limiting part 623 and the second limiting part 624.

[0074] Specifically, mounting parts 625 are provided on both sides of the mounting component 620 so as to be fixedly mounted on the carrier 100 through the mounting parts 625.

[0075] In detail, at least one of the mounting component 620 and the sliding component is made of insulating material to avoid short circuits, thereby improving the safety of the drive mechanism 10.

[0076] Of course, in other embodiments, at least one of the mounting element 620 and the slider may also be made of a non-insulating material.

[0077] For further information, please refer to [link / reference]. Figure 10 The toggle member 400 includes a toggle body 410 and a toggle post 420 disposed on the toggle body 410. The toggle body 410 is used to toggle the output member 500, and the toggle post 420 is used to abut against the first contact portion 613 or the second contact portion 614.

[0078] In this embodiment, by abutting the second contact portion 614 with the actuating post 420, the trajectory member 610 can be driven away from the movement path of the actuating member 400, so as to avoid collision and enable the actuating member 400 to smoothly rotate the output member 500; by abutting the first contact portion 613 with the actuating post 420, the actuating member 400 can be driven away from the output member 500, so as to avoid contact or abutment with the output member 500 during the reset process, thereby affecting the reset stability.

[0079] In detail, the actuating post 420 is cylindrical to reduce the contact area between the actuating post 420 and the track member 610, making their sliding more stable and smooth; and the actuating post 420 is made of insulating material to avoid problems such as short circuits and improve safety performance.

[0080] Of course, in other embodiments, the toggle post 420 may also be made of a non-insulating material.

[0081] Furthermore, the toggle body 410 of the toggle member 400 is movably disposed on the drive member 300, and the first contact portion 613 is used to contact the toggle member 400 and drive the toggle member 400 to move along a preset direction so that the toggle member 400 moves away from the output member 500 during the reset process.

[0082] In this embodiment, the toggle body 410 can slide along a preset straight line direction under the action of the track member 610, or rotate in a preset clockwise or counterclockwise direction, thereby moving away from the output member 500 during the reset process.

[0083] Furthermore, the toggle member 400 also includes a second reset member 430. The toggle body 410 is movably disposed on the drive member 300. The second reset member 430 is disposed on the carrier 100 and connected to the toggle body 410. The second reset member 430 is used to make the toggle body 410 have a tendency to move in a direction opposite to a preset direction.

[0084] Furthermore, the actuating member 400 also includes a limiting member 440, which is disposed on the driving member 300. The limiting member 440 is used to limit the rotation angle of the actuating member 400. Therefore, by the combined action of the limiting member 440 and the second reset member 430 on the actuating body 410, the actuating body 410 can be limited to a fixed angle.

[0085] For further information, please refer to [link / reference]. Figure 11 and Figure 12 The carrier 100 includes a first side plate 120 and a second side plate 130. The driving member 300 is movably disposed between the first side plate 120 and the second side plate 130. The reset spring 110 is disposed on the first side plate 120 and acts on the driving member 300.

[0086] In this embodiment, the output component 500 is rotatably mounted on the second side plate 130, and the trajectory component 610 is mounted on the second side plate 130 to abut against the toggle component 400 during the resetting process, so that the toggle component 400 disengages from the output component 500. The reset spring 110 is mounted on the first side plate 120, the trajectory component 610 is mounted on the second side plate 130, and the drive component 300 is mounted between the first side plate 120 and the second side plate 130, making its structure reasonable and occupying little space, thus reducing the overall length and volume of the drive mechanism 10.

[0087] Furthermore, the second side plate 130 is provided with a through hole 131, which is used for the actuating post 420 to pass through so that the actuating post 420 can abut against the track member 610.

[0088] In this embodiment, the through hole 131 can also serve to limit the movement trajectory of the toggle post 420.

[0089] Furthermore, at least one of the first side plate 120 and the second side plate 130 is provided with a guide hole 121, and the driving member 300 is provided with a guide post. The guide post is disposed in the guide hole 121 and can move along the extension direction of the guide hole 121, thereby improving the stability of the driving member 300 driving the actuating member 400 to move relative to the first side plate 120 and the second side plate 130.

[0090] In this embodiment, the guide post is also a pin connecting the actuating member 400 to the driving member 300, thereby reducing the number of parts or structural components on the driving member 300 and facilitating processing.

[0091] Further, please refer to Figure 4 and Figure 5The output component 500 includes a rotating component 510 and a rotating shaft 520. The rotating component 510 is disposed on the rotating shaft 520, which is rotatably disposed on the second side plate 130. The first side plate 120 is provided with an opening 122 for the rotating shaft 520 to pass through. One end of the rotating shaft 520 passing through the opening 122 is used to connect with the actuator 11, thereby driving the actuator 11 to close or open the circuit through the rotating shaft 520.

[0092] In detail, the rotating member 510 is provided with at least four actuating parts 530, namely two commonly used side actuating parts 530 and two spare side actuating parts 530. The two actuating parts 530 located on one side of the rotating member 510 are used to contact one of the toggle members 400, and the two actuating parts 530 located on the other side of the rotating member 510 are used to contact the other toggle member 400.

[0093] Further, please refer to Figure 13 and Figure 14 The actuator 11 includes a base 700, a gear set 800, and an actuator output component 900.

[0094] In this embodiment, the gear set 800 and the actuator output component 900 are disposed on the base 700, and the gear set 800 and the actuator output component 900 are rotatably connected to the shaft 520. The gear set 800 and the actuator output component 900 are connected in a transmission manner. The actuator output component 900 is connected to the contact to drive the contact to rotate between the closed and open positions, thereby realizing the switching function of the changeover switch 1 and thus meeting the electrical requirements.

[0095] Furthermore, the number of gears includes at least one, and when there are multiple gears, the multiple gears mesh with each other, thereby realizing that the drive mechanism 10 and the actuator 11 are stacked and non-coaxial, which is reasonable in layout, helps to reduce the size of the changeover switch 1, and the modular design is beneficial to production.

[0096] Furthermore, the gear set 800 includes a first transmission gear 810 and a second transmission gear 820. The first transmission gear 810 is fixedly disposed on the rotating shaft 520. The first transmission gear 810 and the second transmission gear 820 mesh with each other. The second transmission gear 820 is rotatably disposed on the base 700 and connected to the contact, so as to drive the contact to rotate between the closed and open positions under the drive of the drive mechanism 10.

[0097] Furthermore, the actuator 11 also includes a central shaft 1000, a first mounting portion 821 for the second transmission gear 820, and a second mounting portion 910 for the actuator output component 900. The two ends of the central shaft 1000 are respectively mounted on the first mounting portion 821 and the second mounting portion 910, so that the second transmission gear 820 is connected to the actuator output component 900 in a transmission connection.

[0098] In detail, the actuator 11 also includes an energy storage spring 1100, the second transmission gear 820 is provided with a first connecting part, the actuator output part 900 is provided with a second connecting part opposite to the first connecting part, one end of the energy storage spring 1100 is connected to the base 700, and the other end is provided with a connecting shaft 1200, with the two ends of the connecting shaft 1200 respectively provided at the first connecting part and the second connecting part.

[0099] In summary, this application provides a driving mechanism 10 and a changeover switch 1. The electromagnetic component 200 drives the driving element 300 to move relative to the carrier 100, thereby causing the driving element 300 to drive the toggle element 400 to rotate the output element 500. The output element 500 then drives the moving contact of the actuator 11 to rotate between the closed and open positions, thus realizing the switching function of the changeover switch 1. During the reset process of the driving element 300, the track element 610 abuts against the toggle element 400, ensuring that the toggle element 400 and the output element 500 remain separated during the reset process. This prevents the toggle element 400 from contacting or abutting against the output element 500 and causing impact, thus avoiding affecting the reset speed and making the reset process smoother. Therefore, it effectively improves the structural stability and reliability of the changeover switch 1, effectively extends its service life, and ensures electrical safety.
