[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 6 As shown, a universal switch panel includes a base 1. Inside the base 1, a partition 2 divides the inner cavity of the base 1 into a first cavity 11 and a second cavity 12. A circuit board 3 is installed in the second cavity 12, and a support plate 4 is installed in the first cavity 11. A button inner liner 5 is hinged to the support plate 4. A button panel 6, capable of swinging the button inner liner 5, is mounted on the top of the button inner liner 5. An elastic pressing part 21 is provided on the partition 2. A connecting hole 41, corresponding to the elastic pressing part 21, is provided on the support plate 4. The button inner liner 5 has a pressing post 51, one end of which, when the button panel 6 is pressed, can press the elastic pressing part 21 through the connecting hole 41, causing the elastic pressing part 21 to press against the switching element on the circuit board 3. Thus, the pressing post 51 on the button inner liner 5 does not need to extend excessively downwards, reducing cost, and it can also accommodate pressing posts 51 of different lengths, increasing its versatility.

[0030] Specifically, at least two elastic pressing parts 21 are provided, at least two corresponding connecting holes 41 are provided, and at least one top pressing post 51 is provided. This utility model, through the standardized design of the support plate and partition, ensures that the number of connecting holes on the support plate and the elastic pressing parts on the partition are fixed and their positions correspond, and that the number of top pressing posts is less than or equal to the number of elastic pressing parts and connecting holes. This allows the switch panel to be applicable to switch products with different numbers of keys, such as single-key, double-key, four-key, and six-key switch panels, without the need to replace the support plate and partition, greatly improving the product's versatility, significantly reducing the types of materials, and lowering mold development, production management, and warehousing costs.

[0031] Specifically, the partition 2 has first strip-shaped holes 22 corresponding to the elastic pressing parts 21. The elastic pressing part 21 is an elastic arm with one end connected to the inner wall of the first strip-shaped hole 22. The free end of the elastic pressing part 21 extends upward and can extend into the through hole 41 to contact the top pressing post 51. The first strip-shaped hole 22 provides deformation space for the elastic pressing part 21. When the top pressing post 51 squeezes the elastic pressing part 21, the elastic pressing part 21 can deform and press down on the switching element on the circuit board 3 to realize the on / off control of the circuit.

[0032] In this invention, a first snap-fit ​​device 7 is provided between the support plate 4 and the partition 2 to snap the partition 2 onto the support plate 4, and a second snap-fit ​​device 8 is provided between the base 1 and the support plate 4 to lock the support plate 4 so that the partition 2 presses the circuit board 3 tightly into the second cavity 12. This invention, through the cooperation of the first and second snap-fit ​​devices, achieves rapid snap-fit ​​fixing between the partition, support plate, and base, ensuring the stability of the connection between components while simplifying the assembly process and improving production efficiency. Furthermore, the concealed snap-fit ​​design makes the appearance more concise and aesthetically pleasing.

[0033] Specifically, the first snap-fit ​​device 7 includes a snap-fit ​​opening 71 on the partition 2 and a first buckle 72, one end of which can pass through the snap-fit ​​opening 71 and snap onto the back of the partition 2. During installation, the first buckle 72 is passed through the snap-fit ​​opening 71 and snapped onto the back of the partition 2, thereby achieving the snap-fit ​​fixation between the partition 2 and the support plate 4.

[0034] Specifically, the second latching device 8 includes a latching groove 81 on the side wall of the bracket plate 4 and a second latch 82 on the inner side wall of the first cavity 11 that can cooperate with the latching groove 81. When the bracket plate 4 is installed into the first cavity 11, the second latch 82 engages with the latching groove 81, locking the bracket plate 4 in place, thereby pressing the circuit board 3 tightly into the second cavity 12 by the partition plate 2.

[0035] Furthermore, a support post 52 is provided at the lower end of the button liner 5, and a spring piece 42 is provided on the bracket plate 4. When the button panel 6 is pressed, it can be deformed by the support post 52, and after the deformation recovers, it pushes the support post 52 back to its original position, so that the button liner 5 and the button panel 6 are reset to a parallel state. Specifically, the bracket plate 4 has a second strip hole 43 corresponding to the spring piece. One end of the spring piece is connected to the inner wall of the second strip hole 43, and the second strip hole 43 provides deformation space for the spring piece. When the button panel is pressed, the spring piece can drive the button liner 5 and the button panel to quickly reset, solving the problem of misalignment and unevenness between multiple buttons, and making the overall appearance and aesthetics better.

[0036] Specifically, the spring piece 42 is provided with a positioning hole 421, and the support column 52 includes a support portion 521 that presses against the upper end surface of the spring piece 42 and a plug portion 522 provided on the support portion 521 with one end inserted into the positioning hole 421. The plug portion 522 is inserted into the positioning hole 421, which can position the support column 52 and ensure the accuracy and stability of the fit between the support column 52 and the spring piece 42.

[0037] In this invention, the button liner 5 includes multiple elastic button portions 53 and connecting portions 54 connecting the middle of two adjacent elastic button portions 53. A gap 55 extending from both ends of the elastic button portions 53 towards the connecting portion 54 is provided between the two adjacent elastic button portions 53. Multiple top-pressing columns 51 are provided and distributed at the ends of the elastic button portions 53. The middle part of the button liner 5 is hinged to the middle part of the support plate 4 via a hinge device 9. The gap 55 allows each elastic button portion 53 to swing independently, avoiding mutual interference between buttons. Furthermore, the button liner can be used on single-button switches, four-button switches, and six-button switch products, further improving product versatility and reducing product storage costs.

[0038] Specifically, the hinge device 9 includes a hinge pin 91 located in the middle of the support plate 4 and a hinge ear assembly 92 located in the middle of the button inner liner plate 5. The hinge ear assembly 92 includes two opposing locking blocks 921, with a locking groove 93 formed between the two locking blocks 921 for the hinge pin 91 to engage. Through the cooperation between the hinge pin 91 and the locking groove 93, the hinge between the button inner liner plate 5 and the support plate 4 is realized, ensuring that the button inner liner plate 5 can swing flexibly.

[0039] Specifically, multiple hinge pins 91 are provided and spaced apart on the support plate 4, and multiple sets of hinge ear assemblies 92 are provided one-to-one and spaced apart on the button inner liner plate 5. The arrangement of multiple hinge pins 91 and hinge ear assemblies 92 further improves the stability of the connection between the button inner liner plate 5 and the support plate 4 and the flexibility of swing.

[0040] When using this universal switch panel, since the number of top pressure posts 51 is less than or equal to the number of elastic pressing parts 21 and connecting holes 41, different button liner plates 5 with different numbers of top pressure posts 51 and different button panels can be set to adapt to the switching needs of different numbers of buttons, without the need to replace the bracket plate 4 and partition plate 2, which greatly improves the versatility of the product and reduces costs.
