[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] In a specific embodiment of the present invention, Figures 1 to 3 As shown, an elevator button is specifically disclosed. The elevator button has a square shape and includes a button seat 1, a circuit board 2, a pressing structure and a panel assembly. The circuit board 2 is embedded in the bottom of the button seat 1. The pressing structure includes a pressing frame and a pressing seat 4. The pressing frame is embedded in the button seat 1. The pressing seat 4 is clamped on the pressing frame. The pressing seat 4 is made of translucent plastic. The pressing frame is composed of two U-shaped pressing frames 3. The pressing frame 4 is clamped on the bottom edge of the U-shaped pressing frame 3. The two U-shaped pressing frames 3 are rotatably connected to each other. Each U-shaped pressing frame 3 is rotatably connected to the button seat 1. When the pressing seat 4 presses any one of the U-shaped pressing frames 3, the two U-shaped pressing frames 3 are linked together, and the panel assembly is clamped on the pressing seat 4.

[0025] A spring 5 is provided between each U-shaped pressing frame 3 and the button seat 1. There are three springs 5 on each U-shaped pressing frame 3. The three springs 5 are all arranged at one end away from the opening of the U-shaped pressing frame 3, and are respectively arranged in the middle and on both sides of the U-shaped pressing frame 3. The spring 5 is used to reset the U-shaped pressing frame after being pressed down.

[0026] One end of the opening end of the U-shaped pressing frame 3 is provided with a connecting shaft 31, and the other end is provided with a connecting hole 32. When two U-shaped pressing frames 3 are assembled, the connecting shaft 31 is rotatably installed in the connecting hole 32. Connecting columns 33 are respectively arranged on both sides of the U-shaped pressing frame 3. Both ends of the connecting column 33 extend out of the U-shaped pressing frame 3. One end is inserted on the outer wall of the button seat 1, and the other end is arranged in a groove on the inner wall of the button seat 1. When any position on one side of the U-shaped pressing frame far from the opening end is pressed downward, since the opening end of the U-shaped pressing frame 3 is rotatably connected to the button seat 1 and another U-shaped pressing frame 3 at the same time, the opening end of the U-shaped pressing frame 3 moves upward, and the opening end of the other U-shaped pressing frame 3 also moves upward, and the position far from the opening end is pressed downward synchronously.

[0027] The button seat 1 includes a button base 11 and a button frame 12, and the button frame 12 is connected to the button base 11 in a snap-fit manner. The panel assembly includes a light-transmitting character sheet 6 and a decorative frame 7. The light-transmitting character sheet 6 is clamped on the pressing seat 4, and the decorative frame 7 is arranged outside the panel 6 and fixed on the button frame 12.

[0028] The circuit board 2 is provided with a light-emitting diode 21 and a switch button 22. The switch button 22 is arranged at the inner center of the circuit board 2. The number of the light-emitting diodes 21 is several, and they are respectively arranged around the switch button 22. The pressing seat 4 presses the switch button 22.

[0029] The operation process of the elevator button of the present invention is as follows: Press the light-transmitting character sheet 6 of the elevator button panel assembly. The light-transmitting character sheet 6 drives the pressing seat 4 to press downward. The pressing seat 4 presses the U-shaped pressing frame 3. When a certain part of a single U-shaped pressing frame 3 is pressed downward by force, the other U-shaped pressing frame is pressed downward synchronously, so that the whole pressing seat 4 is pressed downward. The pressing seat 4 presses the switch button 22 at the center of the circuit board 2, thereby turning on the elevator button.

[0030] In another embodiment of the present invention, as Figures 4 - 6 The outer shape of the elevator button is rectangular. A spring 5 is arranged between each U-shaped pressing frame 3 and the button seat 1. The number of the springs 5 on each U-shaped pressing frame 3 is two. The two springs 5 are both arranged at one end far from the opening of the U-shaped pressing frame 3 and are respectively arranged on both sides of the U-shaped pressing frame 3. The spring 5 is used for resetting after the U-shaped pressing frame is pressed downward. The rest of the structure of the rectangular elevator button is the same as that of the square-shaped elevator button.

[0031] The beneficial effects of this embodiment are as follows: Due to the setting of the linked U-shaped pressing frame, the elevator button with a long-shaped structure only needs to install one switch button to achieve the sensitive operation of the entire elevator button, which plays a role in cost savings compared to the phenomenon of installing multiple switch buttons in the prior art.

[0032] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
