Dismantling the fiber optic pressure sensor solves the problem of the fixed position of the existing pressure sensor installed under the mattress. The pressure sensor is closely attached to the mattress, which often makes the user feel a foreign body sensation, but it is impossible to adjust the position of the pressure sensor. The problem of affecting the sleep quality of the user overcomes the problem that the pressure sensor is fixed on the bed board and cannot be disassembled when it needs to be replaced.

2. The upper cover of the pressure sensing end on the top surface of the optical fiber pressure sensor is provided with a multi-layer circular protective cover, which can connect the optical fiber pressure sensor to the top surface of the groove through the circular protective cover to receive the pressure from the mattress. The cover is a downwardly recessed circular umbrella-shaped structure, which can make the circular protective cover fit more closely with the pressure end of the optical fiber pressure sensor.

Detailed ways

In order to make it easier to understand the technical means, creative features, goals and effects realized by the present invention, the present invention will be further described below in conjunction with the specific embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention. , not all. Based on the examples in the implementation manner, other examples obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

Example 1

As shown in Figure 1-2, an optical fiber pressure sensor-based smart bed includes a bed board 5, and a mattress 1 is installed above the bed board 5.

The bottom surface of the mattress 1 is provided with a groove 2 along the length direction of the mattress 1, the top surface of the bed board 5 is fixed with a mounting base 4 along the length direction of the bed board 5, the mounting base 4 is located in the groove 2, and the top surface of the mounting base 4 is along the mounting base 4. Two parallel slide rails 3 are arranged in the length direction, and a movable slider 11 is slidably connected to the sliding rail 3. The movable slider 11 is detachably connected with the optical fiber pressure sensor 10, and the movable sliders 11 are fixedly connected by a connecting plate 13. A positioning screw 12 is installed through the center of the connecting plate 13, and the positioning screw 12 is threadedly connected to the threaded hole 6. The threaded hole 6 is provided with several equidistant holes along the length direction of the mounting base 4, and the threaded hole 6 is located between the two slide rails 3;

The circular protective cover 7 is made of silicone material, and the circular protective cover 7 is a circular umbrella-shaped structure recessed downward.

The slide rail 3 is in the shape of a long rope, and the movable slider 11 is sleeved on the slide rail 3 . The movable slider 11 is fixed with a connecting piece 15 , and the connecting piece 15 is installed on the optical fiber pressure sensor 10 through the connecting screw 14 .

A plurality of support legs 16 are mounted on the bottom edge of the bed board 5 .
