Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] 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.

[0040] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] As described in the background section, current operating devices suffer from complex structural designs. Specifically, the linkage mechanism in such devices typically includes an upper linkage, a lower linkage, and an intermediate linkage. The upper and lower linkages are connected via the intermediate linkage, and the applied force during operation is transmitted sequentially through the upper linkage and the intermediate linkage to the lower linkage. However, due to the large number of components used in this linkage mechanism, it not only increases assembly difficulty and reduces assembly efficiency but also leads to higher overall production costs.

[0044] Based on this, please refer to Figures 1-5 The present invention provides an operating device 100 and a changeover switch, which can effectively improve the aforementioned technical problems, that is, improve assembly efficiency and reduce manufacturing costs. The operating device 100 and the changeover switch will be described in detail below.

[0045] This embodiment provides a changeover switch (not shown in the figure). The changeover switch includes an operating device 100 and a contact device. The operating device 100 is used to drive the contact device to perform opening and closing actions to realize the switching between the main power supply and the backup power supply, thereby ensuring the safe operation of the power system and the continuous stability of the production process.

[0046] For details, please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the structure of the operating device 100 provided in this embodiment. Figure 2 This is an exploded view of the operating device 100 provided in this embodiment. Figure 3 This is a partially exploded view of the operating device 100 provided in this embodiment. (In conjunction with...) Figures 1-3 The operating device 100 includes a bracket 10, a main shaft 20, a first drive linkage mechanism 30, a second drive linkage mechanism 40, and a linkage component 50.

[0047] The bracket 10 includes a first bracket 11 and a second bracket 12 spaced apart. The main shaft 20 passes through the first bracket 11 and the second bracket 12, and the main shaft 20 has a first mounting part 21 and a second mounting part 22 arranged opposite to each other. The first mounting part 21 and the second mounting part 22 are both located between the first bracket 11 and the second bracket 12.

[0048] The first drive linkage mechanism 30 includes a first electromagnet 31, a first closing lever 32, a first upper connecting rod 33, a first lower connecting rod 34, and a first energy storage elastic element 35, all located between the first bracket 11 and the second bracket 12. The first electromagnet 31 is movably connected to the first closing lever 32, and the first closing lever 32 is rotatably connected to both the first bracket 11 and the second bracket 12. The first upper connecting rod 33, the first lower connecting rod 34, and the first mounting part 21 are hinged sequentially, and the first upper connecting rod 33 is rotatably connected to both the first bracket 11 and the second bracket 12. One end of the first energy storage elastic element 35 is connected to the first closing lever 32, and the other end of the first energy storage elastic element 35 is connected to the hinge joint of the first upper connecting rod 33 and the first lower connecting rod 34.

[0049] The second drive linkage mechanism 40 includes a second electromagnet 41, a second closing lever 42, a second upper connecting rod 43, a second lower connecting rod 44, and a second energy storage elastic element 45, all located between the first bracket 11 and the second bracket 12. The second electromagnet 41 is movably connected to the second closing lever 42, and the second closing lever 42 is rotatably connected to both the first bracket 11 and the second bracket 12. The second upper connecting rod 43, the second lower connecting rod 44, and the second mounting part 22 are hinged in sequence, and the second upper connecting rod 43 is rotatably connected to both the first bracket 11 and the second bracket 12. One end of the second energy storage elastic element 45 is connected to the second closing lever 42, and the other end of the second energy storage elastic element 45 is connected to the hinge joint of the second upper connecting rod 43 and the second lower connecting rod 44.

[0050] The linkage 50 is slidably disposed on both the first bracket 11 and the second bracket 12, and the two ends of the linkage 50 are respectively hinged to the first closing lever 32 and the second closing lever 42.

[0051] Understandably, in the first drive linkage mechanism 30 of the operating device 100, the first upper linkage 33 is directly hinged to the first lower linkage 34, which can transmit the force applied by the first energy storage elastic element 35 to the first mounting part 21, thereby realizing the rotation of the main shaft 20. Similarly, in the second drive linkage mechanism 40, the second upper linkage 43 is also directly hinged to the second lower linkage 44, and transmits the force applied by the second energy storage elastic element 45 to the second mounting part 22, which can also realize the rotation of the main shaft 20. That is to say, the linkage mechanism in the operating device 100 is all about the upper and lower linkages being hinged. Compared with the prior art, the intermediate linkage structure is eliminated, and the rotation of the main shaft 20 can still be realized, thereby realizing the closing or opening operation of the corresponding power supply. Therefore, the operating device 100 has a simple structure, reduces the number of parts, thereby improving assembly efficiency and reducing manufacturing costs.

[0052] It should be noted that the operating device 100 drives the main shaft 20 to rotate through the coordinated operation of the first drive linkage mechanism 30, the second drive linkage mechanism 40, and the linkage member 50, thereby realizing the corresponding power supply closing and opening operations. Specifically, when it is necessary to close the main power supply and open the backup power supply, the first electromagnet 31 can be energized, causing its iron core to extend and drive the first closing lever 32 to rotate relative to the first bracket 11 and the second bracket 12. At this time, on the one hand, the first closing lever 32 can apply force to the first energy storage elastic element 35, causing the first upper connecting rod 33 and the first lower connecting rod 34 to rotate, and transmit the force to the first mounting part 21, realizing the relative rotation of the main shaft 20, thereby driving the contact device to perform the closing operation of the main power supply; on the other hand, the first closing lever 32 can also drive the linkage 50 to slide on the first bracket 11 and the second bracket 12. Through the action of the linkage 50, the second closing lever 42, the second energy storage elastic element 45, the second upper connecting rod 43 and the second lower connecting rod 44 can also perform corresponding actions and act on the second mounting part 22.

[0053] In other words, by setting the linkage 50, the first drive linkage mechanism 30 and the second drive linkage mechanism 40 can move synchronously and act on the main shaft 20 at the same time, thereby improving the stability and reliability of the closing and opening operations.

[0054] Furthermore, it should be noted that in this embodiment, the first electromagnet 31 and the first closing lever 32 are movably connected in the following manner: a pull rod is hinged to the iron core of the first electromagnet 31, and the pull rod has an elongated hole, in which the pin of the first closing lever 32 is movably disposed; similarly, the second electromagnet 41 and the second closing lever 42 are movably connected in the following manner: a pull rod is also hinged to the iron core of the second electromagnet 41, and the pin of the second closing lever 42 is movably disposed in the elongated hole of the pull rod. Of course, in other embodiments, the first electromagnet 31 and the first closing lever 32, and the second electromagnet 41 and the second closing lever 42, may also be provided with other movably connected methods.

[0055] Combination Figure 2 and Figure 3The first support 11 is provided with a first rotating shaft 111, and the second support 12 is provided with a second rotating shaft 121; the first drive linkage mechanism 30 also includes a first pin 36 and a second pin 37, the first closing lever 32 is provided with two first pin holes 321, the two ends of the first upper link 33 are provided with two second pin holes 331 and two third pin holes 332 respectively, the first lower link 34 is provided with two fourth pin holes 341, the first pin 36 passes through two first pin holes 321, the first rotating shaft 111 passes through one of the second pin holes 331, the second rotating shaft 121 passes through the other second pin hole 331, and the second pin 37 passes through two third pin holes 332 and two fourth pin holes 341 respectively; the two ends of the first energy storage elastic member 35 are connected to the first pin 36 and the second pin 37 respectively.

[0056] By setting the first pin 36 and the second pin 37, the installation of the first energy storage elastic element 35 can be facilitated, and the energy storage and release effect of the elastic element can be improved. In addition, the first upper connecting rod 33 and the first lower connecting rod 34 can be directly hinged through the second pin 37, which is simple in structure and can improve assembly efficiency.

[0057] In order to further improve the energy storage and release effect of the first energy storage elastic element 35 and enhance the overall stability of the closing and opening of the operating device 100, the number of the first energy storage elastic elements 35 can be set to multiple, and the multiple first energy storage elastic elements 35 are spaced apart along the extension direction of the first pin 36 or the second pin 37.

[0058] Similarly, in this embodiment, the first bracket 11 is provided with a third rotating shaft 112, and the second bracket 12 is provided with a fourth rotating shaft 122; the second drive linkage mechanism 40 also includes a third pin 46 and a fourth pin 47, the second closing lever 42 is provided with two fifth pin holes 421, the two ends of the second upper connecting rod 43 are respectively provided with two sixth pin holes 431 and two seventh pin holes 432, the second lower connecting rod 44 is provided with two eighth pin holes 441, the third pin 46 passes through two fifth pin holes 421, the third rotating shaft 112 passes through one of the sixth pin holes 431, the fourth rotating shaft 122 passes through the other sixth pin hole 431, and the fourth pin 47 passes through two seventh pin holes 432 and two eighth pin holes 441; the two ends of the second energy storage elastic member 45 are respectively connected to the third pin 46 and the fourth pin 47.

[0059] It is easy to understand that by setting the third pin 46 and the fourth pin 47, the installation of the second energy storage elastic element 45 can be facilitated, and the energy storage and release effect of the elastic element can be improved. In addition, the second upper connecting rod 43 and the second lower connecting rod 44 can be directly hinged through the fourth pin 47, which also simplifies the structure and improves assembly efficiency.

[0060] In order to further improve the energy storage and release effect of the second energy storage elastic element and enhance the overall stability of the operation device 100 during closing and opening, the number of the second energy storage elastic element 45 can also be set to multiple, and the multiple second energy storage elastic elements 45 are spaced apart along the extension direction of the third pin 46 or the fourth pin 47.

[0061] It should be noted that in this embodiment, there are two of both the first energy storage elastic element 35 and the second energy storage elastic element 45; of course, in other embodiments, the number of the first energy storage elastic element 35 and the second energy storage elastic element 45 may be one, three, or four, etc. Furthermore, in this embodiment, the first energy storage elastic element 35 and the second energy storage elastic element 45 are specifically springs; however, in other embodiments, the first energy storage elastic element 35 and the second energy storage elastic element 45 may also be spring sheets, rubber sleeves, or other elastic structures.

[0062] Furthermore, the changeover switch may also have a dual-open position, that is, by driving the contact device through the operating device 100, both the main power supply and the backup power supply can be in an open state. Therefore, in order to ensure that the operating device 100 can be stably locked when in the dual-open position, and to ensure the reliability and safety of the operation process, in this embodiment, the operating device 100 also includes a dual-open locking mechanism 60. The dual-open locking mechanism 60 includes a dual-open lever 61, a locking shaft 62, and a third electromagnet 63, all disposed between the first bracket 11 and the second bracket 12. The dual-open lever 61 is connected to both the first mounting part 21 and the second mounting part 22, and the locking shaft 62 is connected to the third electromagnet 63.

[0063] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of the double-splitting lever 61 provided in this embodiment, combined with... Figures 2-4 The double-splitting lever 61 is equipped with a locking protrusion 611, which engages with the locking shaft 62. As is easily understood, when a double-splitting locking operation is required, the first drive linkage mechanism 30, the second drive linkage mechanism 40, and the linkage member 50 work together to rotate the main shaft 20 to the double-splitting position. During this process, the main shaft 20 also drives the double-splitting lever 61 to rotate, causing the locking protrusion 611 to engage with the locking shaft 62, locking the main shaft 20 and achieving double-splitting locking. This prevents accidental closing of the switch during use and improves safety. When double-splitting unlocking is required, energizing the third electromagnet 63 causes its core to retract, moving the locking shaft 62 downwards and disengaging it from the locking protrusion 611, thus unlocking the main shaft 20.

[0064] To facilitate the installation of the double-split lever 61 and the main shaft 20, and to improve the synchronization of the double-split lever 61 with the rotation of the main shaft 20, the first mounting part 21 and the second mounting part 22 are respectively provided with a first mounting hole 211 and a second mounting hole 221. The double-split lever 61 is provided with a third mounting hole 612 and a fourth mounting hole 613 that are arranged opposite to each other. The double-split locking mechanism 60 also includes a first mounting shaft 64 and a second mounting shaft 65. The first mounting shaft 64 passes through both the first mounting hole 211 and the third mounting hole 612, and the second mounting shaft 65 passes through both the second mounting hole 221 and the fourth mounting hole 613.

[0065] Furthermore, in this embodiment, the first lower connecting rod 34 has a fifth mounting hole 342, and the first mounting shaft 64 passes through the first mounting hole 211, the third mounting hole 612, and the fifth mounting hole 342 simultaneously. The second lower connecting rod 44 has a sixth mounting hole 442, and the second mounting shaft 65 passes through the second mounting hole 221, the fourth mounting hole 613, and the sixth mounting hole 442 simultaneously.

[0066] In other words, the first lower connecting rod 34, the first mounting part 21, and the double-split lever 61 are all connected through the same hinge point, that is, they are connected through the first mounting shaft 64; similarly, the second lower connecting rod 44, the second mounting part 22, and the double-split lever 61 are also connected through the same hinge point, that is, they are connected through the second mounting shaft 65. This arrangement reduces the number of assembly steps and connecting parts, thereby further improving assembly efficiency, reducing manufacturing costs, and simplifying the overall structure of the operating device 100.

[0067] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the spindle 20 provided in this embodiment, combined with... Figure 5 The spindle 20 includes a spindle body 24 and a spindle seat 23. The spindle seat 23 is sleeved on the spindle body 24 and is located between the first bracket 11 and the second bracket 12. The spindle seat 23 has a first mounting part 21 and a second mounting part 22 that are disposed opposite to each other.

[0068] Please combine them together Figures 2-5 To facilitate the installation of the double-split lever 61, the double-split lever 61 is also provided with a seventh mounting hole 614, which is located between the third mounting hole 612 and the fourth mounting hole 613; the main shaft body 24 is simultaneously inserted through the first bracket 11, the seventh mounting hole 614 and the second bracket 12.

[0069] To further improve the installation stability of the double-splitter lever 61, in this embodiment, the spindle seat 23 is provided with a limiting step 231, which abuts against the inner wall of the seventh mounting hole 614.

[0070] Please continue to combine Figure 2 The bracket 10 also includes at least one fixed shaft 13, with its two ends connected to the first bracket 11 and the second bracket 12, respectively. By providing the fixed shaft 13, the overall structural strength of the operating device 100 can be improved.

[0071] It should be noted that in this embodiment, the number of fixed shafts 13 is three; of course, in other embodiments, the number of fixed shafts 13 can also be one, two, or four, etc.

[0072] In addition, in order to limit the sliding distance of the linkage 50, the bracket 10 also includes a limiting shaft 14, which is located at the top of the first bracket 11 or the second bracket 12. The linkage 50 has a sliding groove 51, and the limiting shaft 14 is located in the sliding groove 51.

[0073] In summary, the embodiments of this utility model provide an operating device 100 and a changeover switch. The operating device 100 is directly hinged to the first lower connecting rod 34 via the first upper connecting rod 33, and transmits the force applied by the first energy storage elastic element 35 to the first mounting part 21, thereby enabling the rotation of the main shaft 20. Similarly, the second upper connecting rod 43 is also directly hinged to the second lower connecting rod 44, and transmits the force applied by the second energy storage elastic element 45 to the second mounting part 22, also enabling the rotation of the main shaft 20. It is easy to understand that the linkage mechanism in this operating device 100 consists entirely of upper and lower connecting rods hinged together. Compared with the prior art, this eliminates the need for an intermediate connecting rod structure, yet still enables the rotation of the main shaft 20, thereby achieving the corresponding power supply closing or opening operation. Therefore, the operating device 100 has a simple structure, reduces the number of parts, thereby improving assembly efficiency and reducing manufacturing costs.

[0074] The changeover switch includes an operating device 100, which has all the beneficial effects of the operating device 100.
