[0025] Example

[0026] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides an elevator button, including an outer cylinder 1, a pressing character sheet 2, an anti-dropping frame 3 and a circuit board 4, the inner side of the outer cylinder 1 is embedded with a pressing character sheet 2, the center of the pressing character sheet 2 is fixedly provided with a boss 201, the top of the outer cylinder 1 is fixedly provided with an anti-dropping frame 3 by fixing glue, the center of the outer cylinder 1 is fixedly provided with a circuit board 4, the upper surface of the circuit board 4 is provided with a touch switch 401 in parallel, and a plurality of rebound components are provided at the inner bottom of the outer cylinder 1.

[0027] During actual use, when assembling the elevator button, the structural glue is applied on the top of the outer cylinder 1, the pressing piece 2 is placed in the outer cylinder 1, and then the anti-detachment frame 3 is adhered to the structural glue on the top of the outer cylinder 1, and the boss 201 on the pressing piece 2 is embedded in the central through hole of the anti-detachment frame 3, and the assembly of the elevator button can be completed, which is simple and convenient to operate.

[0028] In this embodiment, the side length of the boss 201 is smaller than the side length of the pressing character sheet 2 , and the pressing character sheet 2 matches the upper opening of the outer cylinder 1 , and the boss 201 matches the central through hole of the anti-slip frame 3 .

[0029] In this embodiment, the boss 201 is made of transparent silicone, and the height of the boss 201 is equal to the thickness of the anti-slip frame 3, ensuring the light transmittance and wear resistance of the boss 201, and ensuring that the boss 201 and the anti-slip frame 3 are on the same plane, ensuring the user's experience of touching and pressing the character sheet 2.

[0030] In this embodiment, four touch switches 401 are provided, and the four touch switches 401 are respectively provided at four corners of the upper surface of the circuit board 4. By providing four touch switches 401, when an individual touch switch fails, the remaining touch switches can still work normally, so that the elevator button can continue to work, reducing the failure rate of the elevator button, extending the service life of the elevator button, and enhancing the user experience.

[0031] In this embodiment, four rebound assemblies are provided, and the four rebound assemblies are respectively arranged in four directions of left, right, front and back of the outer cylinder 1 .

[0032] In this embodiment, the rebound assembly includes a guide sleeve 5, a rebound block 501, a first spring 502, a guide rod 503, a mounting block 504, a slider 505, a second spring 506, a fixed block 507 and a connecting rod 508. The guide sleeve 5 is fixedly arranged at the inner bottom of the outer cylinder 1. The first springs 502 are fixedly arranged on the left and right sides of the guide sleeve 5. The rebound block 501 is fixedly arranged on the top of the first spring 502. The guide rod 503 is fixedly arranged at the inner center of the guide sleeve 5 through two mounting blocks 504. The slider 505 is penetrated on the left and right sides of the guide rod 503. The second spring 506 is fixedly arranged between the slider 505 and the mounting block 504. The fixed block 507 is fixedly arranged at the bottom center of the rebound block 501. The fixing block 507 and the slider 505 are rotatably connected by a connecting rod 508 through a pin.

[0033] In this embodiment, when the first spring 502 and the second spring 506 are in a naturally extended state, the upper portion of the rebound block 501 extends out of the upper opening of the guide sleeve 5 , so that the rebound block 501 can rebound the pressed character sheet 2 .
