Detailed ways

The specific embodiment of the utility model is described below in conjunction with accompanying drawing.

The human body induction display floor of the utility model is set based on the principle of a piezoelectric sensor, and works by sensing the gravity of the human body stepping on it.

Referring to Fig. 1 and Fig. 2, the human body induction display floor includes three-layer structures arranged at intervals in the vertical direction, and the uppermost layer is a transparent top plate 10, which can be made of plexiglass or tempered glass. The thickness is around 15mm. The middle layer is a display board 20, which can display characters, lights, etc. through a plurality of distributed LED lights 60; the display board 20 of this layer is also integrated with related circuit devices for display control and data processing. The bottom layer is the bottom plate 30, which plays an auxiliary supporting role.

Wherein, a plurality of pillars 40 are directly arranged between the uppermost top plate 10 and the lowermost bottom plate 30 for support. In addition, several piezoelectric sensors are provided under the top plate 10 , and each piezoelectric sensor is provided with a piezoelectric sheet 50 . Each piezoelectric sensor is correspondingly provided with a tightness adjustment device, such as a screw 70 that passes through the bottom plate 30. One end of the head of the screw 70 stays outside the bottom plate 30, and the other end is connected to the bottom of the piezoelectric sheet 50. touch.

In a preferred embodiment shown in Figure 1, four pillars 40 and two piezoelectric sensors are provided, the four pillars 40 are arranged at the four corners of the display floor, and One piezoelectric sensor is provided between the two pillars 40 on one side of the display floor and another piezoelectric sensor is arranged between the two pillars 40 on the opposite side.

Refer to Figures 1 to 3 for coordination. When someone steps on the uppermost top plate 10, the top plate 10 will be deformed, causing the piezoelectric sheet 50 to also deform, thereby causing the piezoelectric sensor to generate charges, and then convert the charges into a voltage. After this voltage is processed by filter 21, signal amplifier 22 and A/D converter 23, the microprocessor 24 controls the display board 20 to display corresponding information according to the sampling signal. The aforementioned devices 21 to 23 for data processing and the microprocessor 24 for display control are all integrated on the display board 20 .

The above is the specific implementation structure for arranging LED lights for text or light display. It can be set up in hotels and other places for location guidance, or it can be set up to display "Welcome" information at the door of shops and other places; it can also be used in places such as dance halls, controlled by a microprocessor, according to the rhythm of stepping on the top plate The change of gravity brought by the difference changes the changing rhythm of the light, so that when the pedaling rhythm is fast, the lighting changes quickly, and when the pedaling rhythm is slow, the lighting changes slowly.

In other embodiments, another information display structure can also be used, for example, an integrated or external sounding device can be added, which is similar to the control method of the light display, and the sound is emitted when the top plate is trampled; or further according to the difference in trampling gravity , to change the sound. Alternatively, the display board can be set up as a display, outputting an image or video when stepping on it, and so on.

Although the content of the present invention has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions of the present utility model will be obvious to those skilled in the art after reading the above content. Therefore, the protection scope of the present utility model should be defined by the appended claims.
