Description

Technical Field

[0001] This utility model relates to the field of wall switches, specifically to a switch oscillating plate assembly and a switch having the oscillating plate assembly. Background Technology

[0002] Currently, wall switches include a switch button, a toggle arm, and a switch sway assembly. The switch sway assembly includes a switch sway and a spring. The connection structure between the switch sway assembly and the toggle arm can be referenced in Chinese Utility Model Patent Publication No. CN222801662U, "A Self-Resetting Switch"; Figure 7 and Figure 8 As shown, a connecting piece 97 is formed on the upper part of the switch lever. The connecting piece 97 is rectangular, and the lower end of the spring fits onto the outside of the connecting piece 97. That is to say, as Figure 8 As shown, the width of the connecting piece 97 is slightly smaller than the inner diameter of the deflector spring, so in Figure 8 From a visual perspective, the connecting piece 97 has a very small range of lateral movement relative to the spring, which is beneficial for stable switch operation. When the user presses the switch button, the switch button causes the lever arm to swing. Since the upper part of the spring is located inside the lever arm, and the upper part of the switch lever is located within the fork area at the lower end of the lever arm, the lever arm can drive the switch lever to swing and achieve the switch switching function. Furthermore, the moving contact on the switch lever presses against the stationary contact of the switch through the elastic restoring force of the spring (generated by the elastic compression deformation of the spring); Figure 8 As shown, when the lever spring and connecting piece 97 are parallel and aligned, both the upper and lower ends of the connecting piece 97 are located at the diameter of the lever spring. However, since the lever spring is cylindrical, during the process of the lever arm moving the switch lever, when the connecting piece 97 and the upper part of the lever spring are tilted relative to each other, because the width of the connecting piece 97 is only slightly smaller than the inner diameter of the lever spring, when the upper end of the connecting piece 97 swings relative to the lower end of the lever spring, the connecting piece 97 will be blocked by the inside of the lever spring. Similarly, when the lower end of the connecting piece 97 swings relative to the lower end of the lever spring, the connecting piece 97 will be blocked by the inside of the lever spring. The lower end of the switch swivel is also blocked by the internal spring. Therefore, the relative swing amplitude between the lower end of the connecting plate 97 and the spring is very small, which makes the bending deformation of the middle part of the spring more obvious. When the switch swivel reaches the limit position (that is, when the moving contact on the switch swivel contacts the stationary contact of the switch), the bending amplitude of the middle part of the spring is the largest. On the one hand, this can easily lead to spring fatigue and breakage, and on the other hand, it makes the switch swivel less flexible, which is not conducive to flexible switching. Therefore, the switch swivel assembly of the existing technology needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a switch swivel assembly that facilitates flexible switching.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The present invention relates to a switch oscillating plate assembly, comprising an oscillating plate and a spring. The upper part of the oscillating plate has an insert portion, which is disposed inside the lower end of the spring. The upper part of the insert portion gradually narrows from bottom to top, and the lower part of the insert portion gradually narrows from top to bottom.

[0006] Preferably, the left edge and the right edge of the insert portion are both curved edges.

[0007] Preferably, a groove is formed on the swing plate, the lower end of the insert portion is integrally connected to the bottom of the groove, and the lower end of the spring is disposed in the groove.

[0008] Preferably, the upper end of the groove has a chamfered opening.

[0009] Preferably, a rounded corner is formed between the lower end of the insert portion and the bottom of the groove.

[0010] Preferably, the lower end of the spring has a tapered portion, and the tapered portion has a flat end face.

[0011] This utility model also provides a switch, including the switch swash plate assembly described in any of the above claims; it also includes a lever arm, the upper part of which is disposed within the lever arm.

[0012] Compared with the prior art, the advantages of this utility model are as follows: (i) By setting the upper part of the insert portion to gradually narrow from bottom to top and the lower part of the insert portion to gradually narrow from top to bottom, the insert portion can swing relative to the lower end of the spring, which is beneficial to the flexible switching.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] The switch swash plate assembly of this utility model, such as Figures 1 to 4 As shown, the device includes a swing plate 1 and a spring 2. The upper part of the swing plate 1 has an insert portion 11, which is located inside the lower end of the spring 2. The lower end of the swing plate 1 abuts against a swing support plate connecting to the switch. This swing support plate is used to connect the live wire. Figure 1 As shown, a receiving cavity is formed inside the switch arm 99. The upper part of the spring 2 is located inside the receiving cavity, and the upper end of the spring 2 contacts the inner top of the receiving cavity. The spring 2 is in an elastically compressed deformation state. A fork 991 is formed at the lower end of the switch arm 99. The upper part of the swing plate 1 is located inside the fork 991. When the switch arm 99 swings, the fork 991 moves the swing plate 1, causing the upper part of the swing plate 1 to swing left and right (in... Figure 1 (Under the visual direction), thereby realizing the switching action. For example Figure 3 As shown, the oscillating plate 1 has an upper protrusion formed on one side of the insert portion 11, and the upper end of the upper protrusion is provided with a silver dot 12, which is used as the stationary contact of the conductive contact switch. Figure 5 As shown, the upper part of the insert portion 11 gradually narrows from bottom to top, and the lower part of the insert portion 11 gradually narrows from top to bottom. That is, the middle part of the insert portion 11 is wider, while the upper and lower ends of the insert portion 11 are narrower. The width of the insert portion 11 is... Figure 5 The dimension "W" in the text.

[0024] like Figures 2 to 4 As shown, the insert portion 11 is inserted into the lower end of the lever spring 2, and moves as the lever arm 99 swings, as... Figure 2As shown, when the upper part of the spring 2 is inclined relative to the insert part 11, because the upper end of the insert part 11 is narrower, it can deviate significantly from the inner diameter of the spring 2. Similarly, because the lower end of the insert part 11 is narrower, it can deviate significantly from the inner diameter of the spring 2. This allows the insert part 11 to swing more significantly relative to the lower end of the spring 2, preventing the lower end of the spring 2 from hindering the swing of the insert part 11 relative to the aforementioned swing support plate. This facilitates flexible switch switching. Furthermore, because the insert part 11 can swing more significantly relative to the lower end of the spring 2, the bending amplitude of the insert part 11 relative to the spring 2 is reduced, preventing fatigue fracture caused by repeated bending deformation of the spring 2 and improving the durability of the switch. Figure 4 As shown, because the width of the middle part of the insert portion 11 is larger than the width of the upper and lower ends of the insert portion 11, the middle part of the insert portion 11 (in the vertical direction) can still maintain the inner diameter setting of the spring 2. That is to say, the width of the middle part of the insert portion 11 is set to be slightly smaller than the inner diameter of the lower end of the spring 2, so that the insert portion 11 can be easily inserted into the lower end of the spring 2, but at the same time, it can avoid a large degree of lateral loosening between the lower end of the spring 2 and the insert portion 11. Figure 4 (From the visual direction).

[0025] Furthermore, in Figure 5 From a visual perspective, the left and right edges of the insert portion 11 are both curved. In other words, the upper part of the insert portion 11 is gradually narrowed from bottom to top with a curved transition, and the lower part of the insert portion 11 is gradually narrowed from top to bottom with a curved transition, making the insert portion 11 approximately elliptical. During the relative swinging process between the insert portion 11 and the spring 2, the spiral spring wire of the spring 2 will scrape against the left and right edges of the insert portion 11. Since the left and right edges of the insert portion 11 are both curved, it is beneficial to guide the spiral spring wire of the spring 2 to slide relative to the insert portion 11, avoiding jamming, and further facilitating the flexible relative swinging of the lower ends of the insert portion 11 and the spring 2.

[0026] Furthermore, such as Figure 5 As shown, a groove 10 is formed on the oscillating plate 1, and the lower end of the insert portion 11 is integrally connected to the bottom of the groove 10, as shown. Figure 3 and Figure 4 As shown, the lower end of the spring 2 is located within the groove 10, thus the groove 10 can externally limit the loosening range of the lower end of the spring 2 relative to the swing plate 1. The edge of the groove 10 is located within the fork 991 of the lever arm 99.

[0027] Furthermore, such as Figure 5As shown, the upper end of the groove 10 has a chamfered opening 101. So when the lower end of the spring 2 is put on the outside of the insert part 11, the lower end of the spring 2 is simultaneously inserted into the groove 10. During this process, the chamfered opening 101 can guide the lower end of the spring 2 into the groove 10.

[0028] Furthermore, such as Figure 5 As shown, a rounded corner 113 is formed between the lower end of the insert portion 11 and the bottom of the groove 10, meaning that the transition from the lower end of the insert portion 11 to the bottom of the groove 10 is an arc. Figure 4 As shown, since the spring 2 applies a downward pushing force to the insert portion 11, the lower end face of the spring 2 is in contact with the bottom of the groove 10. The lower end of the spring 2 may scrape against the foot rounded corner 113. By setting the foot rounded corner 113 to guide the lower end of the spring 2, the sliding between the lower end of the spring 2 and the foot rounded corner 113 is prevented from causing a jam.

[0029] Furthermore, such as Figure 6 As shown, the lower end of the spring 2 has a tapered portion 21, and the tapered portion 21 has a flat end face 211. That is, the lower end face of the spring 2 is a flat end face 211, which can be formed by grinding the end of the tapered portion 21. Figure 7 As shown, the end of the existing spring is simply a cut spring wire, thus forming a spring wire end face 961. The spring wire end face 961 is approximately parallel to the axis of the spring, so it may stick to one side of the switch lever, thus hindering the switch lever from swinging relative to the spring. Figure 3 and Figure 4 As shown, during the assembly of the spring 2 and the swing plate 1, the spring 2 may rotate in different directions. Since the lower end face of the spring 2 of this invention is a flat end face 211, it avoids forming an obvious spring wire end face. When the rotation direction of the spring 2 changes, it is not easy for the end of the spring wire of the spring 2 to stick to one side of the swing plate 1, which is relatively beneficial to the lower end of the spring 2 and the swing plate 1 swinging flexibly relative to each other.

[0030] The switch of this utility model, such as Figure 1 As shown, the switch includes a toggle arm 99 and a switch button 98. The switch of this invention also includes the switch lever assembly described above, such as... Figure 1 As shown, the upper part of the spring 2 is located inside the lever arm 99. Specifically, as described above, the upper part of the spring 2 is located inside the receiving cavity of the lever arm 99. The switch button 98 is located on the front side of the lever arm 99 and is fastened to the front end of the lever arm 99. Because the switch lever assembly of this utility model facilitates flexible switch switching, the switch of this utility model also has the advantage of flexible switch switching.
