Description

Intelligent headrest

Technical Field

Background

In recent years, technology development and research on intelligent headrests have been increasing, and related products are also on the market. Generally, an intelligent headrest has one or more functions of sleeping posture detection, headrest height adjustment, breathing detection, sleeping posture adjustment and the like. The sleeping posture detection generally adopts a force sensor placed in a headrest, an air bag for detecting the internal pressure intensity of the air bag or a flexible sensor pressed on the shoulder during sleeping, the breathing detection generally adopts the detection of the pressure of the head on the headrest or breathing sound signals, and the sleeping posture adjustment generally adopts the air bag or a mechanical structure to adjust the height of the headrest. Although there are a number of techniques disclosed for intelligent headrest detection and adjustment, there are two problems in the related art as follows.

Firstly, when a force value sensor detects the pressure of a head on a headrest, the pressure sensor is selected, the force sensor generally adopts three types of sensors, the first type is a flexible sensor, and some intelligent headrest technologies apply the flexible force sensor, but the flexible sensor technology which can realize the detection function and has repeatability and long service life is not mature enough at present, so that the application of the flexible sensor on the intelligent headrest is limited; the second method adopts a method for detecting the pressure in the air bag to detect the acting force of the head on the headrest, which has the problem of difficult modeling, and because the shapes of human heads are different and the contact areas of the heads and the air bag are different during sleeping, the pressure can be influenced, so that the acting force of the head on the headrest can be hardly accurately obtained by the method for detecting the pressure of the air in the air bag; the third type is that a rigid sensor (such as a mature and stable resistance strain type sensor) is used for detecting the force applied by the head to the headrest, so that the detection precision is insufficient or the range is over-measured, the detection precision is insufficient due to the large range selection of the sensor, and the sensor is damaged due to overload when the range selection of the sensor is small.

Secondly, the existing height-adjustable intelligent headrest basically adopts the air bag as a deformation element to adjust the height of the headrest or adjust the posture of the head, and the headrest is softer, so that the air bags in a plurality of arrays are needed for height adjustment, the complexity, the failure rate and the cost are increased, and the service life of the product is shortened.

In view of the above problems, the present invention discloses an intelligent headrest, which determines a sleeping posture and a breathing condition by detecting a pressure of a head on the intelligent headrest, and controls a height or an inclination of the intelligent headrest according to a detection and determination result, so that the detection accuracy is high, the sensor can be prevented from being overloaded, and the structural design is convenient for adjusting the height and the inclination of the head.

Detailed Description

The following is a detailed description of an intelligent headrest according to the present invention, which is given by way of illustration only and not to limit the claims, and the invention is not described as applicable to the prior art.

Embodiment 1 of an intelligent headrest of the present invention (as shown in fig. 1 to 3):

an intelligent headrest is shown in a schematic structural diagram of fig. 1, and comprises a detection device 1 and a headrest wrapping layer 40 serving as a headrest cushion, wherein the detection device 1 is wrapped by the headrest wrapping layer 40, the detection device 1 is invisible because the headrest wrapping layer 40 wraps the detection device 1, and in order to show the position of the detection device, the detection device 1 is shown by a solid line in fig. 1 in the top view direction, and occupies most of the area of the headrest wrapping layer 40, namely the detection device 1 and the headrest wrapping layer 40 are close to each other in length in the direction perpendicular to the picture in fig. 1, when a head is pressed on the headrest wrapping layer 40, the head can be indirectly pressed on the detection device 1 through the headrest wrapping layer 40, and equivalently, a common headrest with the same size is placed on the detection device;

the headrest wrapping layer is made of common soft headrest materials such as memory cotton, latex and fabric, is the same as the material of a common headrest, is prepared into a layered structure or a structure with a cavity in the interior, a detection device 1 is placed between layers or in the cavity, the thickness of the headrest wrapping layer on one side, close to the head, of the detection device is thick, and the thickness of the headrest wrapping layer 40 on the other side, close to the bed, of the detection device is thin; or the common headrest is adopted as a pillow pad, and the common headrest and the detection device are wrapped together by an elastic fabric; or sewing an elastic bag under the common headrest, and putting the detection device 1 into the elastic bag.

As shown in fig. 2 to 3, the detection device 1 includes a support plate 10, a columnar force sensor 20, and a support plate 30, the support plate 10 is used as a support member, the columnar force sensor 20 is used as a sensing member, the support plate 30 is used as a support member, and the support plate 10 is made of a rectangular glass fiber composite plate and has a certain rigidity; the columnar force sensors 20 are piezoresistive force sensors made of high polymer materials, 2 groups of 18 columnar force sensors 20 are arranged on the supporting plate 10 in 9 groups, and the 18 columnar force sensors 20 are arranged in 2 rows and 9 columns; the 9 supporting plates 30 are glass fiber resin composite plates, are respectively placed on the 9 groups of columnar force sensors 20 and are borne by the 9 groups of columnar force sensors 20, gaps are reserved between the edges of two adjacent supporting plates 30, and the 9 supporting plates 30 are arranged in a key-shaped array. Since the supporting plate 10 is a one-piece component, it is easier to wire the column-shaped force sensor 20 on the supporting plate 10, but it is not excluded that the column-shaped force sensor 20 is mounted on the supporting plate 30, for example, when the force sensor is a passive force sensor such as FRID, it will not cause inconvenience in wire connection when mounted on the supporting plate; the columnar force sensor 20 may be bonded to the support plate 10 and the backup plate 30.

Although the column-shaped force sensors 20 made of polymer material have a large strain capacity, in order to prevent excessive compressive deformation, a group (2) of overload prevention pillars 11 is provided as an overload prevention member between each group of column-shaped force sensors 20, and 18 overload prevention pillars 11 are also arranged in an array of 2 rows and 9 columns, the overload prevention pillars 11 are fixedly mounted on the support plate 10 (although it is not excluded that the overload prevention pillars 11 are mounted on the support plate 30) between the support plate 10 and the support plate 30. It is not excluded that the overload prevention unit is a piston structure, for example, a cylindrical overload prevention post 11 mounted on the support plate 10 is inserted into a circular tube mounted on the support plate 30, and the overload prevention post can move like a piston in the circular tube, so that the overload prevention unit can play a role of guiding in addition to the overload prevention, the support plate 30 can be effectively prevented from moving in the horizontal direction (the direction perpendicular to the axis of the overload prevention post), and the support plate 30 can be ensured to be parallel to the support plate 10.

Although the 9 supporting plates 30 in fig. 2 and 3 cover a smaller area than the supporting plate 10, it is not excluded that the supporting plates 30 cover a slightly larger area than the supporting plate 10 and are wrapped by the elastic fabric without affecting the detecting function.

In order to express the positional relationship between the respective components in the top view, all the components in the top view are shown by solid lines, and the hidden components are not shown or hidden by broken lines, for example, in general, since the holding plate 30 blocks the column-shaped force sensor 20 and the overload prevention pillar 11, the column-shaped force sensor 20 and the overload prevention pillar 11 should use broken lines in the top view, or the column-shaped force sensor 20 and the overload prevention pillar 11 are not shown in the top view 2.

When the intelligent headrest is applied, in the plumb direction, the supporting plate 30 of the detection device is arranged above the supporting plate 10, and the supporting plate 30, the supporting plate 10 and the bed are both in the horizontal direction. The force of head pressure on the headrest acts on the supporting plate 30 through the headrest wrapping layer 40, the force applied by the head is attached to one group (two) of the columnar force sensors 20 through each supporting plate 30, if the columnar force sensors 20 are connected to a data acquisition device through signals, the position of the head on the intelligent headrest and the force value of the head acting on the headrest can be judged according to the acting force of the detected head on the supporting plates 30, the lying posture is judged according to the force, and under the general condition, the pressure of the head acting on the intelligent headrest in the supine state is greater than the pressure of the head acting on the intelligent headrest in the lateral lying state. Simultaneously, can make the head act on the pressure of intelligent headrest during breathing and produce the change of less range, the change frequency is the same with respiratory frequency, data acquisition device can analyze the head that detects and judge the appearance of sleeping and whether take place apnea to the pressure of intelligent headrest, can also upload the data of record to supply the user to look over in cell-phone APP, upload to the cloud platform even and be used for product big data analysis or the sleep health detection analysis of product application in-process, can analyze out the number of times of standing up in the sleep process and the number of times of apnea etc. reflect the data of sleep quality.

Generally, under the condition that the height of the supporting plate 30 is fixed, the pressure of the head on the supporting plate is different when the same person lies on the back, on the side and on the prone, the pressure value difference between the side and on the back can reach hundreds of grams, the pressure value difference between the head on the side and on the prone can be small, the pressure of the head on the supporting plate 30 is small due to the slight movement of the head caused by the respiration of the person, the change is generally small, the change is only dozens of grams when the respiration is light, the sensing part of the detection device needs to detect the difference, the precision of the sensing part is required to be high, and the measuring range is not suitable for being selected to be too large. When the force applied to the supporting plate 30 is too large to compress the cylindrical force sensor 20, which causes excessive deformation of the supporting plate, the overload prevention support 11 supports the supporting plate 30 to prevent it from approaching the supporting plate 10 further, thereby preventing the cylindrical force sensor 20 from being damaged by over-range due to excessive compression. The detection device is provided with the overload prevention part, so that the sensing part can detect high-precision force value change and can be effectively prevented from being damaged by overload.

The supporting plate 10 is a rigid plate, which means that when the acting force applied by the head is applied, the rigidity of the supporting plate 10 is enough to make the deformation amount not affect the detection performance of the sensing component, and the total deformation amount is not enough to make the human head feel, even when the supporting plate 30 is pressed by the foot or the body, etc., the supporting plate 30 and the supporting plate 10 are not deformed plastically.

The adoption of multiple (9 in this embodiment) supporting plates 30 to divide the whole headrest force detection area into multiple sections (9 in this embodiment) is beneficial to eliminating interference factors, for example, if a whole supporting plate with the same length as the supporting plate 10 is used to detect head pressure, if a person puts his hands on the headrest during sleeping, the force of the hands acting on the supporting plate is also taken into the force applied by the head to cause error in adjusting the height of the headrest, because the adoption of multiple sections of supporting plates 30 can judge and eliminate the force applied by the hands when the head and the hands are positioned on different supporting plates 30, when the hands and the head are superposed together, the hands are generally rested on the head, and can also be judged by the number of the supporting plates covered by the acting force and the pressure range to correct, and the measured force under the condition is larger than the comfortable force value, the height of the headrest needs to be reduced, and the reduction of the height of the headrest does not cause discomfort to the user due to the fact that the arms are cushioned below the head.

Embodiment 2 of an intelligent headrest of the present invention (as shown in fig. 4):

the difference from example 1 is: in this embodiment, the supporting member of the detection apparatus is a folded edge supporting plate 31, the folded edge supporting plate 31 is a rectangular box-shaped sheet metal part without a cover, an opening of the folded edge supporting plate 31 is downward buckled on the columnar force sensor 20, the inner side of the vertical edge of the supporting plate 31 is close to the outer side of the columnar force sensor 20, and the columnar force sensor 20 can also limit the movement of the supporting plate 31 in the horizontal direction. In order to improve the stability of the hem supporting plate 31, four columnar force sensors 20 are arranged on the supporting plate 10 below each hem supporting plate 31, in order to improve the stability of supporting in overload prevention, four overload prevention pillars 11 are arranged below each hem supporting plate 30, and the adoption of a larger or smaller number of supporting plates 30 is not excluded, and the number of the columnar force sensors 20 and the number of the overload prevention pillars 11 are correspondingly changed.

Embodiment 3 of an intelligent headrest of the present invention (as shown in fig. 5 to 7):

the intelligent headrest in the embodiment comprises a detection device, a headrest wrapping layer, an air bag type adjusting device and a control device.

In the present embodiment, the detection device uses the box-shaped support member 12 as the support member, the box-shaped support member 12 is a rectangular parallelepiped metal plate box (having 5 faces, corresponding to standing side baffles erected on the periphery of the support plate 10) without a cover, the cylindrical force sensors 201 support the support plates 30 at the edge portions of the support plates 30, and two adjacent support plates 30 share one set of cylindrical force sensors 201 for support and force value measurement, each support plate 30 is supported at four corners, and the stability is the same as that in embodiment 2, but the number of the cylindrical force sensors 201 is reduced compared with embodiment 2. As shown in fig. 6, the cylindrical force sensor 201 and the holding plate 30 are both located inside the top view of the box-like support member 12; as shown in fig. 7, the four vertical folded edges of the box-like support member 12 are slightly lower than the top of the holding plate 30 in the height direction (the up-down direction in fig. 7), so that when a head load acts on the holding plate 30, the edges of the box-like support member 12 do not prevent the head load from being applied to the holding plate 30, and at the same time, play a role of restricting the movement of the holding plate 30 in the horizontal direction, that is, restricting the holding plate 30 from exceeding the range of the vertical edge of the box-like support member 12 in the top view of fig. 6.

The overload prevention member in this embodiment is two strip-shaped overload prevention metal strips 111 fixedly installed in the box-shaped supporting member 12, and when the supporting plate 30 is subjected to an excessive pressure toward the bottom of the supporting member 12, the overload prevention metal strips 111 are used for supporting the supporting plate 30 to prevent the force value applied to the cylindrical force sensor 201 from exceeding the range of the cylindrical force sensor 201, which causes damage to the cylindrical force sensor 201. Of course, the overload-proof metal strip may be replaced by a frame-shaped member placed in the box-shaped supporting member 12, or a sheet metal folded edge may be further provided at the edge of one circle of the opening of the box-shaped supporting member 12, so as to limit the displacement of the supporting plate 30 by using the folded edge, thereby achieving the function of the overload-proof member. In addition, a folded edge capable of contacting with the folded edge of the box-shaped supporting component 12 can be added at the edge of the supporting component to serve as an overload prevention component, the two folded edges are contacted to prevent the supporting component from further contacting with the supporting component, and any one of the two folded edges which are contacted can be regarded as the overload prevention component.

The headrest wrapping layer comprises a pillow area wrapping layer 41 and a regulating area wrapping layer 42, and the pillow area wrapping layer 41 is used as a pillow pad;

the air bag type adjusting device is used as an adjusting device and comprises an air bag adjusting part 51 and an adjusting supporting plate 52, wherein 4 air bag adjusting parts 51 are arranged between the adjusting supporting plate 52 and the box-shaped supporting part 12 and are respectively positioned at four corner positions of the adjusting supporting plate 52 and the box-shaped supporting part 12, the adjusting supporting plate 52 is positioned at one side of the detecting device close to a bed, the adjusting supporting plate 52 is a plate-shaped part with the same area as or close to the box-shaped supporting part 12, the adjusting supporting plate 52 is arranged in alignment with the box-shaped supporting part 12, and the inclination state and the height of the intelligent headrest are adjusted by adjusting the inflation quantity of the air bag adjusting parts 51. The air bag adjusting member 51 is preferably a multi-layer air bag, which has a smaller area than a single-layer air bag in order to achieve the same lifting height, and thus requires a smaller amount of air when the same height change occurs, thereby facilitating more rapid adjustment of the height and inclination of the intelligent headrest.

A circle of fastening tapes 43 are fixed on the side wall of the box-shaped supporting component 12, the pillow area wrapping layer 41 is a general headrest with a circle of fastening edges around, the pillow area wrapping layer 41 is fixed on the fastening tapes 43 through a circle of fastening tapes, the pillow area wrapping layer 41 and the supporting component of the detection device form a wrapping area, the supporting component and the sensing component of the detection device are wrapped in the wrapping area, and head acting force acts on the supporting plate 30 of the detection device through the pillow area wrapping layer 41;

the adjusting region wrapping layer 42 is an elastic fabric with adhesive buttons on the edge, the adjusting region wrapping layer 42 is fixed on the adhesive button strip 43 through the adhesive buttons on the edge, the adjusting region wrapping layer 42 and the box-shaped supporting component 12 form a wrapping region, the air bag adjusting component 51 and the adjusting support plate 52 are wrapped in the wrapping region, the distance and the state between the adjusting support plate 52 and the box-shaped supporting component 12 can be changed by adjusting the air quantity in the air bag adjusting component 51, so that the height and the inclination angle of the intelligent headrest are adjusted, the distance between the adjusting support plate 52 and the box-shaped supporting component 12 is increased when the air bag adjusting component 51 is inflated, and the distance between the adjusting support plate 52 and the box-shaped supporting component 12 is reduced when the air bag adjusting component 51 is deflated; when the distance between the adjusting support plate 52 and the box-shaped supporting component 12 is changed, the adjusting area wrapping layer 42 is elastically stretched and contracted, tubular elastic fabric can be used for connecting only the outer edges of the adjusting support plate 52 and the box-shaped supporting component 12, even the non-elastic tubular fabric is used for connecting the adjusting support plate 52 and the outer edges of the box-shaped supporting component 12, and the length of the non-elastic tubular fabric is larger than the maximum distance between the adjusting support plate 52 and the box-shaped supporting component 12.

Divide into the parcel layer of parcel outside detection device regulation area parcel layer 42 and pillow district parcel layer 41's aim at: when the height or inclination of the headrest is adjusted by the air bag adjusting member 51, the material of the pillow area covering 41 is not stretched or compressed by the change in the distance between the adjustment blade 52 and the box-like support member 12, and the detection of the force value by the detecting means is prevented from being affected. If the entire periphery of the smart headrest is wrapped with one elastic fabric, when the distance between the adjustment pallet 52 and the box-like support member 12 is changed, the wrapped elastic fabric is deformed accordingly, thereby affecting the detection force value of the detection means. The wrapping and fixing manner of the adjusting area wrapping layer 42 and the pillow area wrapping layer 41 is not limited to the above manner, as long as the change of the distance between the support member and the adjusting support plate does not affect the pillow area wrapping layer when the height of the intelligent headrest is adjusted. The pillow area wrapping 41 is necessary for the headrest, but the adjustment area wrapping is not necessary, and even the adjustment area wrapping 42 may not be provided, and the normal function of the smart headrest is not affected.

In order to adjust the height and the inclination state of the intelligent headrest at will, 4 air bag adjusting parts 51 respectively use 1 air supply valve and 1 air exhaust valve to control air supply and exhaust, share one air pump or respectively use one air pump, when air needs to be supplied to a certain air bag adjusting part 51, a control device sends signals to control the air supply valve connected with the air bag adjusting part to be opened and the air exhaust valve to be closed, and on the contrary, when air needs to be supplied to a certain air bag adjusting part 51, the air supply valve connected with the air bag adjusting part is closed and the air exhaust valve is opened. Although it is not excluded that two or more air bag adjusting members share the air supply valve and the air discharge valve, it is not surely guaranteed to arbitrarily adjust the tilt direction of the headrest. In order to facilitate noise control, a pump valve box 91 is arranged outside the range wrapped by the headrest wrapping layer, and an air supply valve, an air exhaust valve and an air pump are all arranged in the pump valve box and are connected with the air bag adjusting part 51 through air pipes. The air pump, the air supply valve and the exhaust valve belong to the category of the control device in the embodiment.

The control device is used for detecting and analyzing signals of the cylindrical force sensor 201, and further controlling the height and the inclination state of the intelligent headrest by controlling the air pump, the air supply valve and the exhaust valve, the control device generally comprises an MCU control panel, a signal transmission panel, a man-machine interaction interface and the like, for example, the MCU control panel is developed by adopting a single chip microcomputer, the signal transmission panel converts the signals of the cylindrical force sensor 201 into standard electric signals for the MCU control panel to collect, the man-machine interaction interface can adopt buttons, switches and a touch screen, and can also adopt wireless communication such as Bluetooth and the like to communicate with a mobile phone and the like, a program operated by the mobile phone is used as the man-machine interaction interface, the control device realizes the intelligent headrest control system with a plurality of schemes, the configuration modes are flexible and changeable, components of the control device can be arranged in a pump valve box or in a space wrapped by a headrest wrapping layer, for example, the control device is arranged in a box-shaped support part 12, and may be provided even on a connecting section connecting the portions surrounded by the pump housing 91 and the headrest casing.

The air supply for the air bag adopts an air pump and a switch valve, and can also adopt two communicated air bags, one air bag is used as the air bag adjusting part 51, the other air bag is used as the air bag for air storage, the air bag for air storage is driven and compressed by a motor, a screw rod, a nut and other mechanisms, so that the air supply for the air bag adjusting part 51 can be realized, the air bag for air storage is released to exhaust the air bag adjusting part 51, the air pump is not needed, the noise is convenient to control, and the required space is larger.

It is of course not excluded to use airbag adjusting members having a smaller number than 4 airbag adjusting members 51, for example, two elongated airbag adjusting members are provided only at the left and right ends of the box-like support member 12 shown in fig. 6, or two elongated airbag adjusting members are provided at both ends and one horizontally elongated airbag adjusting member is provided further downward in fig. 6 so that the horizontally elongated airbag adjusting member is positioned below the neck. Although 2 or 3 air bag adjusting parts 51 may be provided for adjusting the height and inclination of the intelligent headrest, when the position of the head on the intelligent headrest is inclined, it is difficult to ensure that the box-shaped support part 12 is maintained in a horizontal state when the height of the intelligent headrest is adjusted, and it is also difficult to adjust the inclination state to an ideal state because the air bag is a communicating vessel and the height square sizes of different portions of the air bag are different when the load is applied to different positions. Since the box-shaped support member 12 is a one-piece rigid member, it requires four sets of air bag adjusting members at most to achieve arbitrary adjustment of the height and tilt of the intelligent headrest.

Because each person feels comfortable in different prone positions, the force applied to the headrest by the head corresponds to a comfort force value, the comfort force values corresponding to the side lying and the back lying are basically the same, the comfort force value is related to the weight of the head and basically equal to the weight of the head when the cervical vertebra is in a natural state and the neck muscles are in a relaxed state, and the value is automatically taught, selected and determined by a user through a data acquisition control system before the intelligent headrest is used. When the sleeping postures of the person are different, the height of the headrest can be adjusted according to the pressure of the head on the supporting plate 30 when the person lies on the side and lies on the back, when the force value measured by the measuring device in the process of using the intelligent headrest is larger than the comfort force value, the height of the headrest is over high, the height of the headrest is required to be reduced, otherwise, the height of the headrest is required to be increased, the force acted on the headrest by the head is kept near the comfort force value, thus, the neck muscles are basically in a relaxed state and cannot be stretched excessively, and the box-shaped supporting component 12 is lifted and lowered in a horizontal state in the process of adjusting the height of the intelligent headrest most comfortably. When the height of the intelligent headrest needs to be increased, the control device controls the air bag adjusting parts 51 to be inflated when the cylindrical force sensor 201 detects that the force of the head acting on the intelligent headrest is smaller than a comfortable force value, and simultaneously controls the four air bag adjusting parts 51 to be inflated respectively according to the output of the inclination angle sensor 21, so that the intelligent headrest keeps the box-shaped supporting part 12 in a horizontal state in the height adjusting process, and the height of the headrest is automatically adjusted to automatically adapt to different sleeping postures.

During normal sleep, breathe and to make the pressure that the head acted on intelligent headrest change along with breathing, when the apnea phenomenon takes place, the value of force change by breathing the production can disappear, judge according to this kind of phenomenon when taking place the apnea, the automatic inclination of adjusting intelligent headrest repeatedly can promote the head and slightly rotate, make the people who sleeps on intelligent headrest stop the apnea phenomenon, can divide into two sets ofly with four gasbag adjusting part 51 during the inclination of adjustment intelligent headrest, fill the gassing for two sets of gasbag adjusting part 51 in proper order, can make box-shaped supporting part 12 do about or the fore-and-aft movement together with the pillow district parcel layer 41 on it, thereby promote the head do around shaking of neck or do the nod, the head movement, thereby make breathe and become normal.

The detection device is also provided with an inclination angle sensor 21 for detecting the inclination angle of the support component, the inclination angle sensor 21 is installed on the inner side horizontal plane of the box-shaped support component 12, the inclination angle sensor 21 is connected to the control device, the control device is favorable for keeping the box-shaped support component 12 and the supporting plate 30 in a horizontal state or in a state close to the horizontal state when the height of the headrest is adjusted through a control air bag or a mechanical mechanism, discomfort caused by the fact that the head inclines or leans forward or leans backward due to the fact that the pressure of the head to the headrest is distributed in the height direction and is not in the center, or the pressure of the air bags on two sides is different due to the fact that the pressure of the head to the headrest is distributed in the horizontal direction vertical to the height, so that the intelligent headrest inclines.

Embodiment 4 of an intelligent headrest of the present invention (as shown in fig. 8 to 17):

the difference between the smart headrest in this embodiment and the smart headrest in embodiment 3 is that the detection device thereof is different:

in the embodiment, a cantilever beam type resistance strain gauge type weighing sensor 22 is used as a sensing component, 8 pairs of resistance strain gauge type weighing sensors 22 are fixedly installed at the box bottom of a box-shaped supporting component 12 in an array manner, a backing plate 13 is arranged between the resistance strain gauge type weighing sensor 22 and the box-shaped supporting component 12, an overload-preventing support 11 is installed on the backing plate 13 (or directly installed on the box-shaped supporting component 12, certainly), the fixed ends of each pair of resistance strain gauge type weighing sensors 22 are adjacent, the loading ends are far away from and oppositely arranged, a unit force transmission component installation plate 221 or a two-position force transmission component installation plate 223 is installed at the loading end of each resistance strain gauge type weighing sensor 22, a unit force transmission component installation plate 221 is installed at the loading ends of two pairs of resistance strain gauge type weighing sensors 22 positioned at the outermost side, the loading ends of the rest of the resistance strain gauge type weighing sensors 22 are provided with a double-position force transmission component mounting plate 223. 14 pairs (28) of force transmission springs 222 as force transmission elastic members are arranged on the unit force transmission member mounting plates 221 or the two-position force transmission member mounting plates 223, one force transmission spring 222 is arranged on each unit force transmission

member mounting plate

221, 2 force transmission springs 222 are arranged on each two-position force transmission member mounting plate 223, and spring positioning columns 2220 for limiting the positions of the force transmission springs 222 are arranged on the unit force transmission member mounting plates 221 or the two-position force transmission member mounting plates 223 at positions corresponding to the axes of the force transmission springs 222 at the positions where the force transmission springs 222 are arranged. 7 folding edge supporting plates 31 are buckled at the top ends of the force transmission springs 222 towards the interior of the box-shaped supporting part 12, each folding edge supporting plate 31 buckles 4 force transmission springs 222, the force transmission spring 222 is positioned between the resistance strain gauge type weighing sensor 22 and the folding edge supporting plate 31, and the folding edge supporting plate 31 indirectly presses on the resistance strain gauge type weighing sensor 22 through the force transmission springs 222. Because the backing plate 13 is placed between the resistance strain gauge type weighing sensor 22 and the box-shaped supporting component 12, a space is provided for the resistance strain gauge type weighing sensor 22 to deform downwards, and a space is also provided for the tail end of the resistance strain gauge type weighing sensor 22 to be provided with the unit force transmission component mounting plate 221 or the two-position force transmission component mounting plate 223, so that the lower end of the resistance strain gauge type weighing sensor 22 and the mounted components cannot contact the box-shaped supporting component 12 when the loading end of the resistance strain gauge type weighing sensor is pressed, and the force value measurement is not influenced. Each of the hem supporting plates 31 has 4 supporting plate positioning holes 311, each of the supporting plate positioning holes 311 is provided with a columnar positioning component, each columnar positioning component extends into the inner ring of the force transmission spring 222 at the corresponding position, so that the positioning of the hem supporting plates 31 in the horizontal plane is facilitated, each columnar positioning component is axially overlapped with the spring positioning column 2220 opposite to the vertical direction of the columnar positioning component, and the lower surface of the columnar positioning component is spaced from the upper surface of the spring positioning column 2220 by a certain distance, so that when the supporting plates 31 move downwards until the supporting plates are pressed on the overload protection support column 11, a gap is reserved between the lower surface of the columnar positioning component and the upper surface of the spring positioning column 2220 all the time.

When the force of the head acts on the hem holding plate 31, the force compresses the force-transmitting spring 222 through the hem holding plate 31, and the force-transmitting spring 222 transmits the force to the resistance strain gauge type load cell 22. When the hem supporting plate 31 is pressed down by the head acting force, the force transmission spring 222 is compressed, the hem supporting plate 31 moves towards the direction close to the box-shaped supporting component 12, at most until the hem supporting plate 31 is supported by the anti-overload strut 11, and after the hem supporting plate 31 is supported by the anti-overload strut 11, even if the pressure is increased for the hem supporting plate 31, the hem supporting plate 31 can not move towards the bottom direction of the box-shaped supporting component 12 continuously. The deformation of the force transmission spring 222 is determined from the initial natural state length of the force transmission spring 222 to the moment when the flanging holding plate 31 is supported by the overload-proof support 11, the force generated by the compression of the force transmission spring 222 is determined under the condition that the specification of the force transmission spring 222 is certain, and the resistance strain gauge type weighing sensor 22 can be ensured not to exceed the range through the selection of the type of the force transmission spring 222 and the distance between the flanging holding plate 31 and the overload-proof support 11. If the force-transmitting spring 222 is not provided, but the flap support plate 31 is in direct contact with the resistance strain gauge load cell 22, it is difficult to prevent overload by the overload prevention stay 11 because the resistance strain gauge load cell 22 has a small deformation in its operating range, which may result in no load application or an over-range.

It is not excluded to use other forms of elastic elements instead of the force-transmitting spring 222 as the force-transmitting elastic member, for example, as shown in fig. 16, one end of a rectangular force-transmitting elastic plate 224 is directly fixed on top of the loading end of the resistance strain gauge type load cell 22, and the flap holding plate 31 is supported upward; as shown in fig. 17, the spring steel 225 with a rectangular cross section folded into an approximate "U" shape is installed between the fold supporting plate 31 and the resistance strain gauge type load cell 22 as a force transmission elastic member, and the expected effect can be achieved. In a word, the force transmission elastic component has the function of enabling the supporting component to generate a certain deformation amount when being pressed by the head, which is beneficial to adjusting the distance between the overload-proof pillar 11 and the folded edge supporting plate 31, when the distance between the overload-proof pillar 11 and the folded edge supporting plate 31 is designed, it should be ensured that when the force-transmitting spring deflection reaches the distance between the overload prevention pillar 11 and the hem holding plate 31, the force generated by the force transmitting spring being compressed is less than the span of the resistive strain gage load cell 22, meanwhile, the distance between the overload protection pillar 11 and the folding edge supporting plate 31 is required to be ensured not to exceed the measuring range of the resistance strain gauge type weighing sensor 22 even if the distance is not accurately adjusted and is a little bit larger than the designed value, for example, the distance between the overload prevention pillar 11 and the folded edge supporting plate 31 is 1mm larger than the designed value, so that the force transmission elastic part is deformed by 1mm more, and the measuring range of the resistance strain gauge type weighing sensor 22 is not exceeded. The force-transferring elastic component can be any elastic component with the same function, and not only comprises a metal elastic component, but also can be nonmetal elastic components with different shapes, such as cylindrical high polymer elastic materials with better resilience. Even a spring steel 225 with a rectangular cross section like that in fig. 17 is formed as a force-transmitting elastic part directly at the edge of the holding plate 31 by sheet metal bending, for example.

Embodiment 5 of an intelligent headrest of the present invention (as shown in fig. 18 to 22):

this example differs from example 4 in that:

in the detection device of the present embodiment, instead of the single cantilever-beam type strain sensor in embodiment 4, a plurality of strain beams 220 are cut out from a single sensor board 130 made of a spring steel plate, the strain beams 220 are bent to be higher than the body of the sensor board (as shown in fig. 19), strain gauges 2201 are respectively attached to the upper and lower surfaces of the strain beams 220, so that the strain beams 220 and the strain gauges 2201 constitute a strain-type sensor, a force transmission spring 222 is disposed at the end of the strain beam to be loaded, and the sensor board 130 is fixedly mounted on the inner bottom surface of the box-shaped support member 12. Since the strain beam 220 is higher than the inner surface of the bottom of the box-like support member 12 after the sensor plate 130 is fixedly attached to the inner bottom surface of the box-like support member 12, it does not hinder the strain beam 220 from deforming in a direction to approach the bottom of the box-like support member 12 when it is pressed. The deformation part of the strain beam 220 is trapezoidal and is an equal strain beam, which is beneficial to reducing the pasting requirement of the strain gauge. Of course, the strain beam may be cut into other shapes, such as a triangle with a sharp outer side (corresponding to a triangle with a sharp upper and lower sides and a wide middle portion in fig. 18). And it is not excluded to cut and bend a strain beam having the same function and structure as the strain beam 220 directly at the bottom of the box-like support member 12 and thereby construct a pressure sensor.

In the embodiment, the herringbone arm heightening devices 6 are adopted to adjust the height and the inclination of the intelligent headrest, as shown in fig. 20, the herringbone arm heightening devices 6 are installed at two ends of the box-shaped supporting part 12, the length direction of the herringbone arm heightening devices is the same as the height direction of a human body, and the herringbone arm heightening devices are positioned between the strain beams 220; the chevron arm adjustment device 6 shown in fig. 20 merely shows its position in top view, in fact it is located below the box-like support member 12, not visible in top view.

The common motor is not excluded to drive the screw rod 66 to rotate through the transmission of a coupler, a belt and the like.

In order to reduce the minimum distance between the adjustment pallet 52 and the box-like support member 12, the box-like support member 12 is projected by a rectangular area from the bottom toward the opening of the box at the position of the herringbone arm raising means 6 shown in fig. 20 for mounting the herringbone arm raising means 6 therein, and the overall length of the herringbone arm raising means 6 is made slightly shorter than the width of the box-like support member 12 as shown in fig. 22, and the top of the herringbone arm raising means 6 can be projected into a part of the box-like support member 12 by using a part of the height of the box-like support member 12. The herringbone arm height adjusting device 6 realizes linear motion by adopting a mode of adding a screw rod and a nut through motor rotation, and does not exclude the mode of realizing linear motion by adopting a pull rope transmission mode and the like.

There are many mechanical height adjusting mechanisms, and besides the herringbone arm solution of the present embodiment, it is not excluded to use a scissor type, telescopic arm type, folding arm type, etc. lifting mechanisms, and all of them can be used to adjust the distance between the box-shaped supporting member 12 and the adjusting support plate 52. Even the height adjusting mechanism of the intelligent headrest is arranged on the bed or embedded in the mattress, or the cantilever lifting mechanism is arranged on the headrest corresponding to the bed head and used for adjusting the height and the inclination angle of the intelligent headrest.
