Description

Technical Field

[0001] The utility model relates to the technical field of switch electrical appliance accessories, and particularly relates to a switch springboard. Background Art

[0002] Ordinary switch springboards and swing piece type switch springboards are common mid-year switch springboard structures. These two types of switch springboards have their respective disadvantages. The disadvantage of the ordinary switch springboard is that the overall pressing feel of the switch is poor, and the feedback feel after the switch is pressed is also poor. The disadvantage of the swing piece type switch springboard is that the connection between the swing piece and the connection piece is unstable. A spring needs to be added between the swing piece and the swing piece to make the swing piece be pressed tightly on the connection piece. And for the swing piece type switch, since its bottom wall has two protruding ends in contact with the support piece, the contact area between the two is small, resulting in a high temperature during use and affecting the overall service life.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings of the specification.

[0021] The present utility model provides the following technical solutions:

[0022] As shown in the appended Figures 1-4 figure, the present utility model discloses a switch springboard, including a springboard body 1, the springboard body 1 has a swing piece structure 2, and a moving contact 3 for controlling the on / off of the circuit is arranged on the swing piece structure 2. Specifically, in this design, the swing piece structure 2 is arranged on the springboard body 1, so that when the swinging part on the switch contacts the springboard body 1, it can drive the springboard body 1 to swing. During the swinging process of the springboard body 1, the swing piece structure 2 on the springboard body 1 can contact or disconnect from the conductive piece as the springboard swings, thereby realizing the on / off control of the switch circuit. And in this design, the swing piece structure 2 and the springboard body 1 are set as an integral structure, so that during the user's use, the user's pressing feel can be improved through the swing piece structure 2, and the springboard body 1 can be used to contact the conductive piece in the switch to realize electrical connection, thereby increasing the contact area with the support piece. Compared with the traditional swing piece, the temperature rise of the springboard body 1 can be reduced, and the service life of the springboard body 1 can be prolonged.

[0023] Further, the swing piece structure 2 and the springboard body 1 are of an integrally formed structure, and the swing piece structure 2 protrudes from at least one side of the springboard body 1 and bends upward toward the springboard body 1. Specifically, in this embodiment, the swing piece structure 2 is made by the integral forming process of the springboard body 1, which ensures the overall strength and stability of the springboard body 1. The design of the swing piece structure 2 takes into account the user's usage habits and feel requirements. Through the structure protruding from at least one side, the user can feel obvious feedback when pressing the switch, enhancing the accuracy and reliability of the operation. At the same time, the swing piece structure 2 bends upward toward the springboard body 1, which can ensure that when the switch acts, the swing piece structure 2 can accurately and stably contact or disconnect from the conductive piece, thereby realizing the on / off control of the switch circuit.

[0024] Refer to the appended Figures 3-4, in another embodiment, two of the swing piece structures 2 are provided, and the two swing piece structures 2 are arranged in a diagonal structure on different sides in the length direction of the springboard body 1. Specifically, in this embodiment, two swing piece structures 2 are designed, and they are arranged in a diagonal structure on both sides of the springboard body 1. This design enables the two swing piece structures 2 on both sides to swing synchronously when the springboard switch is under pressure, thereby ensuring the accuracy and stability of the circuit on-off. At the same time, the two swing piece structures 2 include a first swing piece structure 4 and a second swing piece structure 5, and the tops of the first swing piece structure 4 and the second swing piece structure 5 are in the same plane, making the springboard switch more neat and beautiful in appearance, and also facilitating wire contact with the wiring unit of the external switch, improving the contact area and contact effect. Further, moving contacts 3 are provided on both the first swing piece structure 4 and the second swing piece structure 5, and the moving contacts 3 are used to contact the wiring unit of the external switch. Specifically, in this embodiment, moving contacts 3 are provided on the tops of both the first swing piece structure 4 and the second swing piece structure 5, and these moving contacts 3 are used to contact the wiring unit of the external switch, thereby realizing the control of the circuit on-off.

[0025] Further, the swing piece structure 2 includes a contact mounting portion 6, an inclined surface connecting portion 7, and a support portion 8. The moving contact 3 is provided on the contact mounting portion 6. The support portion 8 is formed by bending 90° upward from one side of the springboard body 1, and the inclined surface connecting portion 7 is provided between the support portion 8 and the contact mounting portion 6. Specifically, in this embodiment, the contact mounting portion 6 is provided at the top of the swing piece structure 2 for mounting the moving contact 3 to ensure stable and reliable contact with the wiring unit of the external switch. The support portion 8 is formed by bending 90° upward from one side of the springboard body 1, which not only provides a stable support for the swing piece structure 2 but also ensures that the swing piece structure 2 can swing smoothly and accurately when under pressure. The inclined surface connecting portion 7 connects the support portion 8 and the contact mounting portion 6. Its design enables the swing piece structure 2 to more smoothly make contact with or disconnect from the conductive sheet when the springboard switch swings, thereby improving the sensitivity and stability of the switch operation. In this design, the length and inclination angle of the inclined surface connecting portion 7 can both affect the contact between the moving contact 3 and the external static contact. In addition, the presence of the inclined surface connecting portion 7 also increases the overall strength of the swing piece structure 2, enabling the springboard switch to maintain good performance during long-term use.

[0026] Further, the contact mounting portion 6, the inclined surface connecting portion 7, and the supporting portion 8 are arranged in sequence from top to bottom. The contact mounting portion 6 is arranged on one side of the supporting portion 8 close to the center of the springboard body 1. A parallel structure is arranged between the contact mounting portion 6 and the supporting portion 8. The inclined direction of the inclined surface connecting portion 7 is that the top end of the supporting portion 8 inclines towards the bottom end of the contact mounting portion 6. Specifically, in this embodiment, the contact mounting portion 6, the inclined surface connecting portion 7, and the supporting portion 8 are arranged in sequence from top to bottom, forming a compact and stable structure. The contact mounting portion 6 is located on one side of the supporting portion 8 close to the center of the springboard body 1. This layout is beneficial to the alignment and contact between the moving contact 3 and the external wiring unit. At the same time, a parallel structure is arranged between the contact mounting portion 6 and the supporting portion 8, ensuring the stability and reliability of the swing piece structure 2 during the swinging process. The inclined direction of the inclined surface connecting portion 7 is that the top end of the supporting portion 8 inclines towards the bottom end of the contact mounting portion 6. This design enables the swing piece structure 2 to more smoothly make contact with or disconnect from the conductive sheet when the springboard swings, thereby improving the sensitivity and stability of the switch operation.

[0027] Further, the included angles between the inclined surface connecting portion 7 and the supporting portion 8 as well as the contact mounting portion 6 are both 135° ± 5°. Specifically, in this embodiment, the included angles between the inclined surface connecting portion 7 and the supporting portion 8 and the contact mounting portion 6 are both 135° ± 4°. This design has been precisely calculated and verified through multiple experiments, which can ensure that the swing piece structure 2 can swing smoothly when subjected to pressure, while avoiding performance problems caused by too large or too small angles. Moreover, the included angles between the inclined surface connecting portion 7 and the supporting portion 8 and the contact mounting portion 6 are changed according to the height of the swing piece structure 2 or the height difference between the moving contact 3 and the static contact on the external conductive sheet, thereby further enhancing the applicability and stability of the springboard switch. When the height of the swing piece structure 2 or the height difference between the moving contact 3 and the static contact on the external conductive sheet changes, the included angles between the inclined surface connecting portion 7 and the supporting portion 8 and the contact mounting portion 6 can be adjusted accordingly. In this way, regardless of how the working environment of the springboard changes, it can ensure that the moving contact 3 of the springboard switch and the static contact of the external conductive sheet always maintain a stable contact state, avoiding circuit failures caused by poor contact.

[0028] Further, corresponding swing limiting ends 9 are formed by protruding on both sides of the springboard body 1. The swing limiting ends 9 are symmetrically arranged on both sides of the springboard body 1. The swing limiting ends 9 are formed by bending upward from both sides of the springboard body 1 into an arc structure, and the radian of the swing limiting ends 9 is 1.9-2 rad. Specifically, in this embodiment, swing limiting ends 9 are provided on both sides of the springboard body 1. These swing limiting ends 9 are formed by bending upward from the springboard body 1 and are used to limit the movement range of the swing piece structure 2 during the swinging process, preventing it from swinging excessively and causing performance degradation or damage. At the same time, the swing limiting ends 9 are set into an arc structure, and this design can reduce stress concentration and improve the stability and reliability of the structure. The radian of the swing limiting ends 9 is accurately calculated and determined to be 1.9-2 rad, and such a radian can meet the performance requirements. This design of the swing limiting ends 9 enables the swing piece structure 2 to swing within a certain range when the switch springboard is under pressure, thereby ensuring the accuracy and stability of the circuit on-off. At the same time, due to the existence of the swing limiting ends 9, it can also effectively prevent users from applying excessive pressure to the switch springboard during use, protecting the internal structure of the switch springboard and extending its service life.
