Detailed Description
The principles and features of the present application are described below in conjunction with the following drawings, the illustrated embodiments are merely illustrative of the present application and are not intended to limit the scope of the present application. All embodiments obtained by the spirit of the present application will fall within the scope of protection of the present application for a person of ordinary skill in the art without any inventive effort.
Please refer to fig. 1 and fig. 2, which are schematic views of a pillow according to an embodiment of the present application. The pillow 100 includes a switch detection circuit 20, a processor 30, a memory 40, a pillow body 110, and a plurality of thin film piezoelectric switches 111, where the plurality of thin film piezoelectric switches 111 are disposed on the pillow body 110, and a gap between two adjacent thin film piezoelectric switches 111 is smaller than a preset threshold.
The switch detection circuit 20 is configured to be connected to the plurality of thin film piezoelectric switches 111, and is configured to monitor on or off of the thin film piezoelectric switches 111.
The processor 30 is connected to the memory 40 and the switch detection circuit 20, respectively, and the memory 40 stores instructions executable by the processor 30, and when the instructions are executed by the processor 30, the processor 30 determines the head position according to the closing information of the thin-film piezoelectric switch 111.
The distance between two adjacent membrane piezoelectric switches 111 is smaller than a preset threshold value, so as to reduce the risk that the membrane piezoelectric switches 111 are not pressed by the head of a user when the head of the user rests on the pillow 100 and the head of the user falls into the gap between the two adjacent membrane piezoelectric switches 111. The specific value of the preset threshold can be set according to different practical situations, as long as it is ensured that the force point of the head of the user cannot fall into the gap between the two adjacent thin-film piezoelectric switches 111 when the user is rested on the pillow 100. For example: the preset threshold may be 1 cm, 2 cm, etc. In addition, since the thin film piezoelectric switch 111 has the characteristic of being closed by force, and the thin film piezoelectric switch 111 is not required to be opposite to the point of force, as long as a certain point in the thin film piezoelectric switch 111 is stressed, the whole thin film piezoelectric switch 111 is closed, the sensitivity of closing or opening the thin film piezoelectric switch 111 is higher, and when the head of a user is rested on the pillow 100, the accuracy of determining the head position of the user through closing or opening the thin film piezoelectric switch 111 is higher.
Further, the shape of the thin film piezoelectric switch 111 may be an elliptical strip shape, and a plurality of thin film piezoelectric switches 111 are arranged in parallel, and when the head of the user presses a corresponding position, the thin film piezoelectric switch 111 corresponding to the head is closed.
The thin-film piezoelectric switch 111 has the characteristic of large contact surface, so that the head position can be accurately and effectively detected. When the thin film piezoelectric switches 111 are only required to be uniformly distributed on the upper layer of the pillow body 110, the shape thereof may be set as required, for example: a matrix of densely packed dots, etc.
Specifically, the processor 30 determines the head position according to the closing information of the thin film piezoelectric switch 111, and specifically includes: judging whether the number of the closed film piezoelectric switches is more than one; if the number of the closed membrane piezoelectric switches is equal to one, determining all the closed membrane piezoelectric switches as switches to be calculated; if the number of the closed membrane piezoelectric switches is more than one, judging whether the positions of all the closed membrane piezoelectric switches are continuous; if the positions of all closed film piezoelectric switches are continuous, taking all closed film piezoelectric switches as switches to be calculated; if the positions of the closed film piezoelectric switches are discontinuous, extracting a group of film piezoelectric switches with continuous positions and the largest number from all the closed film piezoelectric switches as switches to be calculated; and determining the head position according to the switch to be calculated.
It is worth mentioning that: when the positions of the closed film piezoelectric switches are discontinuous, the group number of the film piezoelectric switches with continuous positions can be obtained, and when the group number is larger than a preset alarm value, alarm processing is carried out.
The processor 30 determines the head position according to the switch to be calculated, and specifically includes: when the number of the switches to be calculated is an odd number, the position where the middle membrane piezoelectric switch is located is taken as the head position from the switches to be calculated, and when the number of the switches to be calculated is an even number, the position where the middle two membrane piezoelectric switches are located is taken as the head position from the switches to be calculated.
Referring to fig. 3, the pillow 100 further includes an air bag layer 12. Wherein the airbag layer 12 comprises a plurality of airbags 121. The plurality of thin film piezoelectric switches 111 are disposed on the air bag layer 12, and the air bag 121 is disposed corresponding to the thin film piezoelectric switches 111. Specifically, each air cell 121 corresponds to two thin film piezoelectric switches 111. Because the membrane piezoelectric switch 111 is closed under stress, when the head of a user is rested on the pillow 100, the head of the user generates pressure on the pillow 100 under the action of gravity, the membrane piezoelectric switch 111 located below the head of the user is closed under the action of the pressure, and the switch detection circuit 20 detects the closing or opening of the membrane piezoelectric switch 111 to determine the position of the head of the user so as to control the corresponding air bag 121 to work, thereby adjusting the posture of the head of the user.
In one embodiment, there are two thin film piezoelectric switches 111 for each air cell 121, and it is understood that in some other embodiments, the air cells 121 and the thin film piezoelectric switches 111 may be arranged in a one-to-one correspondence, or in a one-to-three or one-to-many arrangement, etc.
It is understood that the controlling of the operation of the air bag 121 refers to inflating or deflating the air bag 121, when the air bag 121 is inflated or deflated, the height of the air bag 121 changes, and when the head of the user rests on the air bag 121, the head of the user automatically adjusts along with the height change of the air bag 121, so as to adjust the posture of the head of the user.
Referring to fig. 3, in order to better protect the plurality of thin film piezoelectric switches 111 and the air bag layer 12, the pillow 100 may further include a shell 13, the plurality of thin film piezoelectric switches 111 and the air bag layer 12 are disposed in the shell 13, and the plurality of thin film piezoelectric switches 111 are located below a pillow surface of the shell 13, the pillow surface of the shell 13 may be made of a flexible material, and the pillow surface of the shell 13 has a deformation property, so that a pressure applied to the pillow surface may be transmitted to the plurality of thin film piezoelectric switches 111. Of course, in other alternative embodiments, the plurality of thin film piezoelectric switches 111 may also be directly disposed on the pillow surface of the housing 13, and when the head of the user rests on the pillow 100, the head of the user directly contacts with the plurality of thin film piezoelectric switches 111 to directly generate pressure on the plurality of thin film piezoelectric switches 111.
It can be understood that, no matter the plurality of thin film piezoelectric switches 111 are disposed in the housing 13 and also disposed on the pillow surface of the housing 13, the total area of the plurality of thin film piezoelectric switches 111 is preferably the same as the area of the pillow surface, so that the coverage of the plurality of thin film piezoelectric switches 111 is the same as the coverage of the pillow surface, thereby ensuring that the head of the user is necessarily within the coverage of the plurality of thin film piezoelectric switches 111 when the head of the user rests on the pillow 100.
Please refer to fig. 4 and 5, which are schematic views illustrating a thin film piezoelectric switch according to an embodiment of the present disclosure. The thin film piezoelectric switch 111 includes a positive electrode conductive layer 1111, a negative electrode conductive layer 1112, and a flexible partition layer 1113, and the flexible partition layer 1113 is located between the positive electrode conductive layer 1111 and the negative electrode conductive layer 1112. The flexible partition layer 1113 has a number of through holes 1114 therein.
Specifically, as shown in fig. 4, when the thin-film piezoelectric switch 111 is not under pressure, the flexible partition layer 1113 separates the positive conductive layer 1111 and the negative conductive layer 1112 of the thin-film piezoelectric switch 111, and the thin-film piezoelectric switch 111 is in an off state. As shown in fig. 5, when the thin-film piezoelectric switch 111 is pressed, a pressure is applied to the thin-film piezoelectric switch 111 (when the head of a user rests on the pillow 100), the flexible shielding layer 1113 in the middle of the thin-film piezoelectric switch 111 is pressed to deform, the positive conductive layer 1111 and the negative conductive layer 1112 are connected through the through hole 1114 of the flexible shielding layer 1113 to form a circuit loop, and the thin-film piezoelectric switch 111 is in a closed state.
In the embodiment of the present application, the plurality of thin film piezoelectric switches 111 of the pillow 100 are disposed on the air bag layer 12, the air bag layer 12 includes a plurality of air bags 121, and the air bags 121 are disposed corresponding to the thin film piezoelectric switches 111. Since the membrane piezoelectric switch 111 is closed by force, when the head of the user is rested on the pillow 100, the position of the head of the user can be determined by detecting the closing or opening of the membrane piezoelectric switch 111, so as to control the corresponding air bag 121 to work, thereby adjusting the posture of the head of the user. And the distance between two adjacent membrane piezoelectric switches 111 is smaller than a preset threshold value, so as to reduce the risk that the head of the user cannot fall into the gap between two adjacent membrane piezoelectric switches 111 when the head of the user is rested on the pillow 100, and improve the accuracy of detecting the head of the user.
Referring to fig. 6, the pillow 100 further includes a sound detection device 80, the sound detection device 80 is connected to the processor 30, and the sound detection device 80 is configured to collect sound of a user, obtain a sound signal, and send the sound signal to the processor 30. The processor 30 is further configured to perform: analyzing and processing the sound signal, and judging whether the user is in a snoring state; if so, sending a control signal for driving the air bag corresponding to the head position of the user to act.
For example, the sound detection device 80 detects the volume of sound and sends volume information to the process 30. The processor 30 determines whether the user is in a snoring state according to the volume information and the characteristics of the sound, namely the sound size and the snoring characteristics of the user, and if so, triggers the snore stopping operation on the user. After the pillow accurately acquires the head position of a user, the corresponding air bag 121 is driven to act, and a good snore stopping effect can be achieved.
Referring to fig. 7, the switch detection circuit includes a plurality of pull-up resistors 70, one end of each pull-up resistor 70 is connected to the power supply 60, the other end of each pull-up resistor 70 is connected to the positive conductive layer 1111 of the thin film piezoelectric switch 111 and the processor 30, and the negative conductive layer 1112 of the thin film piezoelectric switch is grounded. The other end of the pull-up resistor is used as a detection voltage output end for monitoring the on or off of the thin film piezoelectric switch 111.
The processor 30 includes I O terminals, each of which is connected to one of the above-mentioned detection voltage outputs for detecting the on/off state of the membrane piezoelectric switches 111 connected to the I O terminal, and when the pillow 100 is not acted by external force, all the membrane piezoelectric switches 111 are in the off state, and the voltage detected by the processor 30 is high level. When pressure is applied to the pillow 100, for example: when the head of the user rests on the pillow 100, the thin film piezoelectric switch 111 corresponding to the head of the user is closed, and the voltage detected at the I O terminal corresponding to the closed thin film piezoelectric switch 111 changes from high level to low level. Therefore, the switch detection circuit 20 can detect the level of the voltage output terminal to determine whether the corresponding thin-film piezoelectric switch 111 is in the closed state or the open state. Of course, in other alternative embodiments, the state of the thin-film piezoelectric switch 111 may be determined in other manners, which is not described herein again.
Since the piezoelectric membrane switches 111 have a resistance when being turned on, and the resistance value of the resistance is fixed, and each of the membrane piezoelectric switches 111 is connected in parallel to the power supply 60, when the piezoelectric membrane switches 111 are more closed, the overall resistance is smaller, and the current is larger, therefore, when the head of a user is rested on the pillow 100, the pressing area of the head of the user can be determined by detecting the total current of the plurality of membrane piezoelectric switches 111, the pressure is determined according to the pressing area, and then the force for adjusting the action of the air bag 121 is determined according to the pressure, so as to improve the experience of the user.
It is worth mentioning that: the switch detection circuit 20, the processor 30, the memory 40, the power supply 60, the pull-up resistor 70 and the sound detection device 80 may be wholly or partially disposed in the pillow body 110 of the pillow 100, or wholly or partially disposed outside the pillow body 110.
Please refer to fig. 8, which is a flowchart of a method for determining a head position according to an embodiment of the present application, the method is applied to the pillow, a plurality of thin film piezoelectric switches are disposed in the pillow, a gap between two adjacent thin film piezoelectric switches is smaller than a preset threshold, and the method includes:

Step 802: and judging the position of the head according to the closing information of the film piezoelectric switch.
The membrane piezoelectric switch is closed when being applied with external force and is opened when not being applied with external force, so that when the head of the user is placed on the pillow, the closed membrane piezoelectric switch is caused by the gravity of the head of the user, and therefore, the position of the head of the user can be determined by detecting the closed membrane piezoelectric switch, as shown in fig. 9, step 802 includes:
step 8021: judging whether the number of the closed film piezoelectric switches is greater than one, if so, entering a step 8022, and if so, entering a step 8023;

step 8025: and determining the head position according to the switch to be calculated.
Wherein, according to the switch to be calculated, determining the head position specifically comprises: and when the number of the switches to be calculated is an odd number, taking the position of the middle membrane piezoelectric switch from the switches to be calculated as a head position, and when the number of the switches to be calculated is an even number, taking the position of the middle two membrane piezoelectric switches from the switches to be calculated as a head position.
In the embodiment of the application, when the head of a user is rested on the pillow, the position of the head of the user can be determined by detecting the on or off of the thin film piezoelectric switch, so that the accuracy of judging the head position is improved.
