DETAILED DESCRIPTION

[0044] 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, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0047] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0048] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0049] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0050] With the development of society, people's demand for electricity is gradually increasing, and therefore the requirements for the use of power grids and power transmission and distribution are also gradually increasing. Therefore, the application of automatic transfer switches that can ensure the safety of electricity use is becoming more and more widespread.

[0051] However, when the current conversion switch switches the power position, there may be a problem of contact or abutment between the drive structure and the structure that controls the power contact conversion during the electromagnetic drive resetting process. This may not only cause shaking or vibration during the resetting process, causing problems such as part breakage and failure, seriously affecting the stability and reliability of the product, but may also affect the power switching and fail to ensure the safety of electricity use.

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

[0053] See also Figure 1 The transfer switch 1 provided in the present application includes a driving mechanism 10 and an actuator 11. The driving mechanism 10 is connected to the actuator 11, and the driving mechanism 10 drives the actuator 11 to close or open the switch.

[0054] For details, see Figure 2 and Figure 3The driving mechanism 10 includes a carrier 100, an electromagnetic component 200, a driving member 300, a toggle member 400, an output member 500 and a track member 610, wherein the electromagnetic component 200, the driving member 300 and the toggle member 400 are connected in sequence, the output member 500 and the track member 610 can be movably arranged on the carrier 100, and the output member 500 is connected to the actuator 11. Therefore, the electromagnetic component 200 can drive the driving member 300 to move relative to the carrier 100, so that the driving member 300 drives the toggle member 400 to toggle the output member 500 to rotate, so that the output member 500 drives the actuator 11 to connect the moving contact to rotate between the closed or open position, thereby realizing the switching function of the conversion switch 1; and in the process of resetting the driving member 300, the track member 610 abuts against the toggle member 400, so that the toggle member 400 and the output member 500 are always in a separated state during the resetting process, avoiding the toggle member 400 and the output member 500 from contacting or abutting against each other and generating a collision, thereby avoiding affecting the resetting speed and making the resetting process smoother, thereby effectively improving the structural stability and reliability of the conversion switch 1, effectively extending the service life, and ensuring the safety of electricity use.

[0055] Further, the electromagnetic assembly 200 includes an electromagnetic member 210 and a metal rod 220, and the electromagnetic member 210, the metal rod 220 and the driving member 300 are connected in sequence, and the toggle member 400 is arranged at one end of the driving member 300 away from the metal rod 220. Therefore, by driving the metal rod 220 and the driving member 300 to move through the electromagnetic member 210, the toggle member 400 can be driven to move relative to the carrier 100, thereby toggling the output member 500, so as to complete a power state switching, and thereafter, the driving member 300 can be driven by the electromagnetic assembly 200 to move in the opposite direction to reset, or it can be reset by other components. In this embodiment, a reset spring 110 is also arranged on the carrier 100, and the driving member 300 is reset by the reset member 630 spring after the electromagnetic assembly 200 toggles the output member 500.

[0056] It should be noted that, when the electromagnetic component 200 is not operating, the toggle member 400 is located in the initial position; and after the electromagnetic component 200 drives the driving member 300 to drive the toggle member 400 to toggle the output member 500 and move it to the extreme position, the toggle member 400 is located in the actuating position. The resetting of the toggle member 400 refers to the toggle member 400 returning to the initial position from the actuating position under the driving action of the electromagnetic component 200 or the reset spring 110.

[0057] In detail, the number of the electromagnetic assembly 200, the driving member 300, the toggle member 400 and the track member 610 are two, and they are symmetrically arranged on both sides of the output member 500, so as to achieve the output member 500 rotating in a clockwise or counterclockwise direction through the track members 610 on both sides.

[0058] For further information, see Figure 4 and Figure 6 The track member 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 , and 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 resetting process.

[0060] It is understandable that the track member 610 substantially changes the movement track of the toggle member 400 during the resetting process, so that the track member 610 abuts against the reset toggle member 400 , thereby preventing the toggle member 400 from contacting the output member 500 .

[0061] Therefore, it should be noted that, in some embodiments of the present application, the track member 610 can be fixedly arranged on the carrier 100, and the first contact portion 613 of the track member 610 can allow the toggle member 400 to move in one direction, that is, the toggle member 400 can pass when the toggle member 400 moves from the initial position to the actuation position, and as long as the toggle member 400 moves relative to the carrier 100 under the abutment of the track member 610 during the resetting process of the toggle member 400, the structure of the track member 610 is not specifically limited herein.

[0062] In some other embodiments of the present application, the track member 610 can be movably arranged on the carrier 100, and in the process of the toggle member 400 toggling the output member 500, the toggle member 400 abuts against the track member 610 and drives the track member 610 to move in a direction away from the moving path of the toggle member 400, so that the toggle member 400 enables it to normally toggle the output member 500; and when the toggle member 400 is reset, the track member 610 can return to the moving path of the toggle member 400 again 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] Furthermore, the first contact portion 613 includes a first guide surface 6131 and a first retaining surface 6132 that are connected to each other, the first guide surface 6131 faces the moving path of the toggle member 400 and is away from the reset side of the toggle member 400, and the first guide surface 6131 is used to guide the toggle member 400 into the first retaining surface 6132; the second contact portion 614 includes a second guide surface 6141 and a second retaining surface 6142 that are connected to each other, the second guide surface 6141 is located on the moving path of the toggle member 400, and the second guide surface 6141 is used to guide the toggle member 400 into the second retaining 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 keep the track member 610 away from the moving path of the toggle member 400.

[0064] In this embodiment, at least one of the above-mentioned guide surfaces is inclined, and at least one of the above-mentioned retaining surfaces is non-inclined. Specifically, the first guide surface 6131 and the second guide surface 6141 are arranged in parallel, the first retaining surface 6132 and the second retaining surface 6142 are arranged in parallel, the first guide surface 6131 and the second guide surface 6141 are both inclined, and the first retaining surface 6132 and the second retaining 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 retaining surface 6132 and the second retaining surface 6142 together form a parallelogram, which is convenient for guiding the toggle member 400 onto the first retaining surface 6132 or the second retaining surface 6142, and the first retaining surface 6132 can keep the toggle member 400 on the movement path to prevent interference with the output member 500.

[0065] It should be noted that in the present embodiment, the first guide surface 6131, the second guide surface 6141, the first retaining surface 6132, and the second retaining surface 6142 are all planes, while in other embodiments, they can also be other structures such as curved surfaces, as long as they can achieve the above-mentioned effects, and no specific limitation is made here.

[0066] For more details, please continue to read Figures 7 to 9 The driving mechanism 10 also includes a mounting member 620, and the track member 610 can be movably arranged on the mounting member 620. The mounting member 620 is installed on the carrier 100. The mounting member 620 and the track member 610 together constitute a reset mechanism 600, which is used to abut the toggle member 400 during the resetting process of the toggle member 400 to keep the toggle member 400 away from the output member 500.

[0067] Furthermore, the track member 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 member 620 are slidably connected, the slider 612 is fixedly disposed on the sliding body 611, and a first contact portion 613 is disposed on at least one side of the slider 612. The first contact portion 613 is used to abut against the toggle member 400 during the resetting process of the toggle member 400 to disengage the toggle member 400 from the output member 500.

[0069] In the present embodiment, it can be understood that, in 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 in a direction away from the moving path of the toggle member 400, so that the toggle member 400 enables it to normally toggle the output member 500; and when the toggle member 400 is reset, the track member 610 can return to the moving path of the toggle member 400 again 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 track mechanism also includes a reset member 630, which is arranged on the mounting member 620 and acts on the track member 610 to make the track member 610 have a tendency to remain on the reset track of the toggle member 400.

[0071] In this embodiment, the reset member 630 is a spring, one end of which is connected to the mounting member 620, and the other end is connected to the track member 610. It is understandable that the spring can be in a stretched state or in a compressed state. Thus, the elastic restoring force of the spring acts on the sliding body 611, so that the sliding body 611 always has a tendency to remain in the motion track of the toggle member 400. It should be noted that the reset member 630 can also be directly set on the carrier 100, as long as it is ensured that the reset member 630 can play the above-mentioned role, and no specific limitation is made here.

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

[0073] Furthermore, the mounting member 620 also includes a first limiting portion 623 and a second limiting portion 624, the first limiting portion 623 and the second limiting portion 624 are arranged at intervals, the first sliding portion 621, the first limiting portion 623, the second sliding portion 622 and the second limiting portion 624 are connected in sequence and together form a frame-like structure, the sliding body 611 can be slidably arranged between the first limiting portion 623 and the second limiting portion 624, the first limiting portion 623 and the second limiting portion 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 portion 623 and the second limiting portion 624.

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

[0075] In detail, at least one of the mounting member 620 and the track member 610 is made of an insulating material to avoid a short circuit, thereby improving the safety of the driving mechanism 10 .

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

[0077] For further information, please refer to Fig.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 toggle column 420 against the second contact portion 614, the track member 610 can be driven away from the movement path of the toggle member 400 to play an avoidance role, so that the toggle member 400 can smoothly toggle the output member 500 to rotate; by abutting the toggle column 420 against the first contact portion 613, the toggle member 400 can be driven away from the output member 500 to avoid contact or abutment with the output member 500 during the resetting process, thereby affecting the resetting stability.

[0079] In detail, the toggle post 420 is cylindrical to reduce the contact area between the toggle post 420 and the track member 610, making the sliding between them more stable and smooth; and the toggle 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 non-insulating material.

[0081] Furthermore, the toggle body 410 of the toggle member 400 is movably disposed on the driving 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 is away from the output member 500 during the resetting 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 can rotate along a preset clockwise or counterclockwise direction, so as to be away from the output member 500 during the resetting process.

[0083] Furthermore, the toggle member 400 also includes a second reset member 430. The toggle body 410 is movably disposed on the driving 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 the preset direction.

[0084] Furthermore, the toggle member 400 also includes a limit member 440, which is arranged on the driving member 300 and is used to limit the rotation angle of the toggle member 400.
