[0002] In existing technologies, power converters such as inverters and power transformers typically include electrical switching devices, such as relays, fuses, and contactors. These electrical switching devices include manual switches, which are usually located on the outside of the device. The manual switch handles are often quite short. When the power converter is energized, directly operating the manual switch by hand poses a risk of accidentally touching other live parts, causing component malfunctions, and also presents personal safety risks. Furthermore, because the manual switch handle is short, manually operating it is laborious, leading to a poor user experience and potential misoperation. Moreover, since the electrical switching devices are often installed inside the power converter, manual operation often requires disassembling the power converter's protective cover and other components, making the process cumbersome.

[0003] Therefore, there is an urgent need to propose an electrical switching device and a power converter to solve the above problems. Utility Model Content

[0026] 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 some embodiments of this utility model, but not all embodiments.

[0027] The following is combined Figures 1 to 4 The electrical switching device provided in this embodiment will be further described.

[0028] Please refer to Figure 1-2 The present invention provides an electrical switch device, including an electrical switch device body 1 and an auxiliary toggle mechanism. The electrical switch device body 1 has a manual lever 2, and the auxiliary toggle mechanism includes a rotating shaft mounting bracket 3, a switch lever 5, and a rotating toggle shaft 6. A support base 7 is installed at the bottom of the rotating shaft mounting bracket 3.

[0029] Please refer to Figure 3-4 The rotating toggle shaft 6 includes a central column 61, with a top end rotating column 62 connected to the top of the central column 61 and a bottom end rotating column 63 connected to the bottom of the central column 61. The bottom of the top end rotating column 62 is provided with a toggle limiting ring platform 64. The switch toggle 5 is provided with a toggle limiting drive hole 51 that matches the toggle limiting ring platform 64. The toggle limiting ring platform 64 is inserted into the toggle limiting drive hole 51. One end of the switch toggle 5 is provided with a switch toggle fork 52. The manual lever 2 of the electrical switch device body 1 is located in the switch toggle fork 52.

[0030] In this embodiment, the lever limiting ring 64 and the lever limiting driving hole 51 have a limiting relationship in the horizontal rotation direction. That is, when the lever limiting ring 64 rotates, the switch lever 5 can be driven to rotate through the limiting relationship of the lever limiting driving hole 51.

[0031] The top of the rotating shaft mounting bracket 3 is provided with a top rotating hole 31, which is fitted onto the top end rotating column 62. The support base 7 is provided with a bottom rotating hole 71, and the bottom end rotating column 63 is inserted into the bottom rotating hole 71. Understandably, the bottom rotating hole 71 has a gap that allows the bottom end rotating column 63 to rotate after being inserted into the bottom rotating hole 71.

[0032] In one embodiment, the rotary actuation shaft 6 is integrally formed.

[0033] In this embodiment, the rotating toggle shaft 6 is installed through the top rotating hole 31 and the bottom rotating hole 71. In one embodiment, the switch toggle fork 52 is a U-shaped opening. In other embodiments, the switch toggle fork 52 can be other shapes, such as a rectangular opening, a square opening, an elliptical opening, a circular opening, an irregular opening, etc., as long as the manual lever 2 of the electrical switch device body 1 can be located inside the switch toggle fork 52.

[0034] like Figure 1 - Figure 4 As shown, embodiments of this utility model also disclose the following various more optimized specific structures.

[0035] Continue to refer to Figure 2 The rotating shaft mounting bracket 3 is a gate-shaped frame. The bottom of the gate-shaped frame is provided with fixing screw ears 32. The fixing screw ears 32 are fixedly installed on the support base 7 by the bracket fixing screws 4.

[0036] Understandably, the rotating shaft mounting bracket 3 can also be other shapes, such as a Z-shape, etc.

[0037] In one embodiment, the rotating shaft mounting bracket 3 is integrally formed. The rotating shaft mounting bracket 3 can be formed by bending sheet metal parts, or it can be formed by other materials or processes, such as plastic injection molding.

[0038] A protective plate 8 is provided above the rotating shaft mounting bracket 3. The protective plate 8 is used to separate the electrical switch device body 1 from the top of the protective plate 8. The protective plate 8 is provided with an opening 81, which corresponds to the top of the top end rotating column 62.

[0039] The protective plate 8 has a switch rotation indicator on one side of the exposed hole 81 to indicate the direction of rotation for opening and closing. For example, the left and right sides of the switch rotation indicator are INV and GRID, respectively, where INV represents the inverter and GRID represents the power grid. In an inverter-connected and off-grid system (hereinafter referred to as the system), turning the switch to INV means the system is off and the system is powered by the inverter; turning the switch to GRID means the system is on and the system is powered by the power grid.

[0040] The top surface of the top end rotating column 62 is provided with a tool drive notch 621. Figure 3In this embodiment, the tool-driven notch 621 is a flathead notch. A flathead screwdriver is inserted into the tool-driven notch 621, and then the top end rotating column 62 is rotated, causing the lever limiting ring 64 to rotate, thereby driving the switch lever 5 to rotate. The rotation of the switch lever 5 drives the manual lever 2 to switch on and off. It can be understood that, in addition to being a flathead notch (in which case the corresponding tool can be a flathead screwdriver), the tool-driven notch 621 can also be a Torx-shaped notch, a Phillips head notch, an internal hex notch, etc. Accordingly, when rotating the top end rotating column 62, the corresponding tool can be used (e.g., Torx-shaped screwdriver, Phillips head screwdriver, internal hex screwdriver, etc.).

[0041] Understandably, the area of ​​the aperture 81 is large enough to allow one end of the tool to pass through and be inserted into the tool drive notch 621 and then rotated; the shape of the aperture 81 can be circular, rectangular, square, irregular, etc.

[0042] In one embodiment, the electrical switch body 1 can be fixedly mounted on the support base 7 by screws.

[0043] In another embodiment, the support base 7 is provided with a support frame 72, and the upper end of the support frame 72 is provided with a slot 721, and the lower end of the electrical switch device body 1 is locked in the slot 721.

[0044] In one embodiment, the manual lever 2 on the electrical switch body 1 is located inside the switch toggle fork 52.

[0045] like Figure 1 - Figure 4 The assembly process of the electrical switchgear shown is as follows:

[0046] a. Fix or confine the electrical switch body 1 to the support base 7 by means of screws or clips.

[0047] b. Insert the bottom end rotating column 63 on the rotating toggle shaft 6 into the bottom rotating hole 71 of the support base 7, and then put the toggle limit driving hole 51 of the switch toggle 5 onto the toggle limit ring platform 64. During installation, adjust the switch toggle 5 so that the manual lever 2 enters the switch toggle fork 52.

[0048] c. Then install the rotating shaft mounting bracket 3, so that its top rotating hole 31 fits onto the top end rotating column 62, and use the bracket fixing screw 4 to fix the rotating shaft mounting bracket 3 to the support base 7.

[0049] d. After the above assembly is completed, fix the support base 7 inside the power converter box.

[0050] e. Finally, after all other components are assembled, install the protective plate 8. During installation, ensure that the top end rotating column 62 is aligned with the exposed hole 81 set in the protective plate 8 so that the tool can be inserted and the mechanism can be turned.

[0051] When the above structure is in use, a flathead screwdriver or other appropriate tool is inserted into the tool drive notch 621 of the rotating toggle shaft 6. When the tool is rotated, the top end rotating column 62 drives the toggle limit ring platform 64 to rotate, thereby driving the switch toggle 5 to rotate. The switch toggle 5 transmits torque to the manual lever 2, thereby realizing the closing and opening of the electrical switch device by remote non-contact operation.

[0052] The aforementioned auxiliary toggle mechanism enables manual control of the electrical switch body 1 from a distance outside the protective plate 8, reducing the risk of operators accidentally touching live parts, greatly improving product safety and personal safety. It also increases the lever arm distance, thereby reducing the operator's operating force and achieving the effect of easily toggling the electrical switch, greatly improving the user experience. Furthermore, it has advantages such as simple structure, high efficiency, wide application scenarios, and low cost.

[0053] This utility model also discloses a power converter, which includes the aforementioned electrical switching device.

[0054] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
