DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0036] A switching energy storage operating mechanism, such as Figure 1 , Figure 2 As shown, the energy storage operating mechanism is applied to the changeover switch. The energy storage operating mechanism includes a housing 3, a face cover 2 is fixedly provided on the housing 3, an input drive shaft 1 is rotatably mounted on the face cover 2, an output drive shaft 4 is rotatably mounted on one side of the housing 3, and a rotating shaft 13 is rotatably provided on the other side.

[0037] like Figure 3 As shown, the energy storage operating mechanism is fixedly provided with symmetrically distributed spring limiting plates 7. The spring limiting plates 7 are fixedly installed on the housing 3. The limiting shaft 6 is fixed inside the housing 3 and is located on one side of the spring limiting plate 7. The other side of the spring limiting plate 7 is fixedly provided with an energy storage spring 8, which is sleeved on the spring guide shaft 9.

[0038] An output transmission gear 12 is fixedly connected to one end of the rotating shaft 13. The output transmission shaft 4, the output transmission gear 12, and the rotating shaft 13 are coaxial. An input transmission gear 5 is fixedly provided at one end of the input transmission shaft 1. The input transmission gear 5 is located between the output transmission shaft 4 and the rotating shaft 13, and is positioned above the output transmission gear 12. Figure 4 As shown, the input transmission gear 5 meshes with the output transmission gear 12, and both the input transmission gear 5 and the output transmission gear 12 are incomplete bevel gear structures.

[0039] like Figures 5-9 As shown, the input transmission gear 5 has symmetrically distributed waist-shaped holes 51. One end of the input transmission shaft 1 is fixedly connected to a connecting block, which is connected to the waist-shaped holes 51. The output transmission gear 12 has symmetrically distributed connecting holes 121 at the end away from the rotating shaft 13. An output shaft 11 is fixedly connected inside the connecting holes 121. The end of the output shaft 11 away from the output transmission gear 12 is fixedly connected to the output transmission shaft 4.

[0040] A spring baffle 10 is fixedly mounted on the spring guide shaft 9, and an energy storage spring 8 is fixed between the spring baffle 10 and the spring limiting plate 7. During the movement of the spring guide shaft 9, kinetic energy is stored in the energy storage spring 8.

[0041] like Figures 10-12 As shown, the spring limiting plate 7 has a connecting groove 71, which is slidably connected to the spring guide shaft 9. The spring baffle 10 has a through groove 101, which is connected to the spring guide shaft 9. One end of the spring guide shaft 9 has a straight groove 91, and the other end has a round hole 92, which is rotatably connected to the output shaft 11. The straight groove 91 is slidably connected to the limiting shaft 6.

[0042] The working principle is as follows:

[0043] Insert the appropriate operating handle into the input drive shaft 1 and rotate it clockwise. The input drive shaft 1 connects and engages with the input drive gear 5, causing the input drive gear 5 to rotate. The input drive gear 5 then meshes with the output drive gear 12, causing the output drive gear 12 to rotate. The output drive gear 12 drives the output shaft 11 to rotate. The output shaft 11 then drives the spring guide shaft 9 and the spring baffle 10 to compress the energy storage spring 8 past the energy storage dead point. The energy storage spring 8 then releases, causing the output drive gear 12 to rotate.

[0044] Taking an operating mechanism with a rotation angle of 90° as an example, when the gear ratio between the input transmission gear 5 and the output transmission gear 12 is 1:1, the position change of the output shaft when the input transmission shaft 1 rotates from open to closed is as follows: Figures 13-15 As shown, the output angle of this switch operating device is 90° at this time. A larger angle output can be achieved by adjusting the gear ratio between the input transmission gear 5 and the output transmission gear 12.

[0045] In this embodiment, the switching energy storage operating mechanism has the following advantages: it reduces the complexity of the energy storage operating mechanism, simplifies processing, and reduces costs and failure rates;

[0046] The output shaft has a large rotation angle, achieving at least a 90-degree output angle, or even a larger angle, which significantly improves the electrical performance of the switch.

[0047] Because the kinetic energy of the energy storage spring assembly is set close to the center of the output shaft, it can output a larger angular velocity under the premise of the same energy storage spring assembly release speed, thereby further improving the electrical performance;

[0048] The transmission is smooth, efficient, and requires minimal operating force due to the bevel gear meshing.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 the claimed utility model.
