The technical scheme adopted by the patent for solving the technical problem is as follows:
the utility model provides a steady elevating system of self-adaptation pillow, is dull and stereotyped including the lower floor that supports, the dull and stereotyped higher authority of lower floor set up bilateral symmetry's left gasbag and right gasbag, left gasbag and right gasbag above set up the upper strata flat board, the upper strata flat board above set up the pillow body, left gasbag pass through the trachea and connect left admission valve, right gasbag pass through the trachea and connect right admission valve, left admission valve and right admission valve connect the air pump through "Y" shape trachea, still set up the treater that carries out centralized control, the treater connect electron gyroscope, left admission valve, right admission valve and air pump, the inside balance control algorithm that sets up of treater.
The inclination detection device in the scheme can adopt two setting modes:
(a) the inclination detection device is an electronic gyroscope arranged on the upper flat plate, and the electronic gyroscope sends a component G of gravity acceleration in the left and right directions to the processor after receiving the inquiry signal from the processoryAnd the processor calculates the inclination angle of the upper flat plate: thetay＝arcsin(Gy) Wherein thetayThe left side is higher than the upper flat plate to be positive.
(b) The inclination detection device is a left electronic gyroscope and a right electronic gyroscope which are arranged at two ends of the upper flat plate, and the left electronic gyroscope and the right electronic gyroscope send the components of gravity acceleration in the left-right direction to the processor after receiving the query signal from the processor
And

Detailed Description
This patent is further described below with reference to the accompanying drawings:
as shown in fig. 1, 2(a), 2(b) and 3, the stable lifting mechanism of the self-adaptive pillow comprises a lower flat plate 7 for supporting, a left air bag 5 and a right air bag 6 which are bilaterally symmetrical are arranged on the lower flat plate 7, an upper flat plate 8 is arranged on the left air bag 5 and the right air bag 6, an inclination detection device 10 is arranged on the upper flat plate 8, and a pillow body 9 is arranged on the upper flat plate 8. The inflation or deflation of the left air bag 5 and the right air bag 6 can raise or lower the height of the pillow body 9, so as to provide a comfortable headrest height for users. Because the head of the user is uncertain, the head of the user can be left, right or centered, if one air bag is used, the left-right height imbalance can be avoided in the process of inflation or deflation, and the two air bags are adopted, so that the two air bags can be inflated or deflated in an unbalanced manner according to the output inclination amount of the inclination detection device 10, and finally the balanced lifting of the pillow body 9 is realized.
In order to realize the functions, the left air bag 5 is connected with the left air inlet valve 3 through an air pipe, the right air bag 6 is connected with the right air inlet valve 4 through an air pipe, the left air inlet valve 3 and the right air inlet valve 4 are connected with the air pump 2 through a Y-shaped air pipe, and the processor 1 for centralized control is further arranged and connected with the inclination detection device 10, the left air inlet valve 3, the right air inlet valve 4 and the air pump 2 and is controlled.
The tilt detection device 10 described in this embodiment can use two setting methods:
(a) as shown in fig. 2(a), the tilt detecting device 10 is an electronic gyroscope disposed on the upper panel 8, and the electronic gyroscope sends a component G of gravitational acceleration in the left-right direction to the processor 1 after receiving the inquiry signal from the processor 1YAnd GZAs shown in fig. 3, the processor 1 calculates the inclination angle of the upper flat plate 8:
wherein theta isyThe left side is higher than the upper flat plate 8 in the left-right direction.
(b) As shown in fig. 2(b), the tilt detecting device 10 is a left electronic gyroscope and a right electronic gyroscope disposed at two ends of the upper panel, and the upper panel is a flat panelThe left electronic gyroscope and the right electronic gyroscope receive the inquiry signal from the processor 1 and then send the component of the gravity acceleration in the left and right directions to the processor 1
