Description

Intelligent pillow movement self-adaptive adjusting system and method Technical Field The application relates to the technical field of microstructure systems, in particular to an intelligent pillow core self-adaptive adjusting system and method. Background Along with the development of the intelligent sleep health field, the intelligent pillow has evolved from basic filler improvement to a stage with the functions of height adjustment and partition support. The key point of the improvement of the prior art is how to make the support form of the pillow more accurate and dynamically fit the cervical vertebra physiological curvature which is continuously changed when a user sleeps, thereby realizing the crossing of the function of the pillow core from passive bearing to active adaptation. This requires the pillow core to have the ability to actively adapt or guide fine adjustment of head pose to achieve three-dimensional adaptive support of the head and neck of the user. In the prior art, a motor push rod array is arranged below a pillow surface, and after the sleeping gesture is detected through a pressure sensor, the corresponding push rods are controlled to independently lift in the height direction, so that the partition height adjustment is realized, and the integral supporting curved surface is changed. But each of its execution units, i.e. the pushers, has only a single degree of freedom of rectilinear motion in the vertical direction. This makes the formation of its supporting curved surface entirely dependent on the envelope surface of the discrete lattice constituted by the tips of the pushrods. As can be seen, the three-dimensional micro-displacement capability is lacking, when the head of the user is subjected to unintentional horizontal lateral rotation or sliding during sleep, the solution may not be capable of actively adjusting the horizontal profile of the supporting surface in real time to fit the fine change of the head and neck posture, so that mismatch exists between the supporting curved surface and the dynamically changed cervical vertebra curve, and the accuracy and the comfort of the self-adaptive support are affected. Aiming at the technical problems that the intelligent pillow movement system in the related art cannot dynamically adjust the plane distribution of the supporting points according to the horizontal change of the head posture of the execution unit, so that the fitting degree of the intelligent pillow movement system to the head and neck dynamic change in sleeping is poor, no effective solution is proposed at present. Disclosure of Invention The embodiment of the application provides an intelligent pillow core self-adaptive adjusting system and method, which are used for solving the problem that the intelligent pillow core system in the related art cannot dynamically adjust the plane distribution of supporting points according to the horizontal change of the head posture of an execution unit, so that the fit degree of the intelligent pillow core system to the head and neck dynamic change in sleeping is poor. In a first aspect, in an embodiment of the present application, there is provided an intelligent pillow core adaptive adjustment system, including: the driving layer comprises a plurality of driving modules arranged based on a preset array, and a single driving module comprises a first executing unit and a second executing unit; The first execution unit is used for executing lifting driving along the direction perpendicular to the driving layer; the second execution unit is in transmission connection with the output end of the corresponding first execution unit and is used for allowing the output end of the first execution unit to execute displacement in a preset displacement interval along the direction parallel to the driving layer and positioning the output end of the first execution unit after executing displacement; The flexible force transmission layer is covered on the output ends of all the first execution units of the driving layer and is used for coupling the output ends of all the first execution units so as to form a continuous supporting curved surface; And the control unit is used for cooperatively adjusting the execution actions of the first execution unit and the corresponding second execution unit so as to dynamically reconstruct the three-dimensional form of the supporting curved surface. In some embodiments, the second execution unit comprises a flexible guide mechanism and a locking mechanism; the flexible guide mechanism is connected between the output end of the first execution unit and the support panel, and allows the support panel to execute displacement in a preset displacement interval along a direction parallel to the driving layer; The locking mechanism has a locking state and a releasing state, and is used for releasing the constraint on the flexible guide mechanism in the releasing state so that the support panel can execute displacement
