[0002] According to modern medical research, the human spine is a straight line when viewed from the front, but has three physiological curves when viewed from the side. In order to protect the normal physiological curvature of the neck and waist and maintain normal physiological activities during sleep, people usually use pillows and lumbar pillows when sleeping.

[0003] In order to protect the normal physiological curvature of the neck and waist and maintain normal physiological activities during sleep, it is necessary to use pillows and lumbar pillows that conform to one's own spine. However, people usually use traditional pillows and traditional lumbar pillows.

[0040] The following is combined with Figures 1 to 7 This application is described in further detail.

[0041] The embodiment of the present application discloses a device for customizing a pillow or a lumbar pillow.

[0042] When customizing your pillow:

[0043] Reference Figure 1 The equipment for customizing pillows or lumbar pillows includes a lying frame 1, a mounting frame 2 and multiple detection modules 3. The lying frame 1 is for people to lie flat, the mounting frame 2 is installed at one end of the lying frame 1, and the multiple detection modules 3 are all installed in the mounting frame 2. The multiple detection modules 3 are used in conjunction with the headrest core.

[0044] Reference Figure 2 The detection module 3 is divided into four installation areas, namely a middle installation area 4, a left installation area 5, a right installation area 6 and a top installation area 7. The detection module 3 in the middle installation area 4 is used to detect the lower neck detection area, the upper neck detection area and the head detection area of ​​the headrest core, the detection module 3 in the left installation area 5 is used to detect the left side lying detection area of ​​the headrest core, the detection module 3 in the right installation area 6 is used to detect the right side lying detection area of ​​the headrest core, and the detection module 3 in the top installation area 7 is used to detect the top detection area of ​​the headrest core.

[0045] The mounting frame 2 is composed of a plurality of crisscross longitudinal beams 8, transverse beams 9 and columns 10 to form a square frame. The columns 10 are vertically arranged, and the longitudinal beams 8 and transverse beams 9 are horizontally arranged. The longitudinal beams 8 and transverse beams 9 are perpendicular to each other, and the length direction of the longitudinal beam 8 is parallel to the length direction of the lying frame 1.

[0046] Reference Figure 3 , the detection module 3 includes a support member 11, a driving member 12, a connecting member 13, a pressure sensor 14, a cushion block 15 and a position sensor 16. The support member 11 is horizontally mounted on the longitudinal beam 8, and the driving member 12 is vertically mounted on the support member 11. In this embodiment, the driving member 12 is an electric push rod, the connecting member 13 is horizontally mounted on the output end of the driving member 12, the pressure sensor 14 is mounted on the top of the connecting member 13, the cushion block 15 is mounted on the detection end of the pressure sensor 14, and the top of the cushion block 15 protrudes from the top of the overall mounting frame 2, and the position sensor 16 is installed between the support member 11 and the connecting member 13. The position sensor 16 is electrically connected to the computing module, the computing module is electrically connected to the controller, and the controller is electrically connected to the driving member 12. In this embodiment, the pressure sensor 14 is a contact sensor.

[0047] After placing the headrest core on the top of the mounting frame 2, each detection area of ​​the headrest core can be respectively adapted to the cushion blocks 15 at different positions. When the neck and head of the human body are pressed on the top of the headrest core, since the heights of the tops of all the cushion blocks 15 are the same in the initial state, and since there are physiological curves in the neck and head of the human body, there must be parts of the neck and head that can apply pressure to the cushion blocks 15 at the corresponding positions, and there must be parts of the neck and head that cannot apply pressure to the cushion blocks 15 at the corresponding positions. Therefore, the pressure values ​​detected by the pressure sensors 14 at different positions will be different, and the column heights of the position sensors 16 at different positions will also be different. At this time, the values ​​of the pressure sensors 14 corresponding to all the detection modules 3 are added and averaged by the calculation module, and then the driving member 12 at the corresponding position is controlled by the controller to extend or retract the corresponding length, thereby adjusting the column height of the detection module 3, so that the values ​​of the pressure sensors 14 corresponding to each detection module 3 are close to the average value, so that all the columns are balanced.

[0048] Preferably, due to the long length of the cushion block 15, after the person lies on the flat frame 1, the person's neck and head may not be pressed in the middle of the headrest core, or the person's neck may not be pressed in the middle of the headrest core when the human body is in the left-side lying position or the right-side lying position. In this way, according to the lever principle, the forces at both ends of the cushion block 15 will be uneven, which will cause a large error in the pressure detected by the pressure sensor 14. Therefore, a telescopic rod 17 is installed between the support member 11 and the cushion block 15, and the telescopic rod 17 is vertically arranged, and the two ends of the telescopic rod 17 are respectively connected to the support member 11 and the cushion block 15. In this way, a certain limiting effect can be played on the cushion block 15, so that the cushion block 15 is more evenly stressed, so as to improve the accuracy of the pressure detected by the pressure sensor 14. In this embodiment, the telescopic rod 17 is a detachable structure between the fixed end and the telescopic end.

[0049] Reference Figure 4 and Figure 5 Preferably, a first lower connection assembly 18 is installed between the driving member 12 and the supporting member 11, and a first upper connection assembly 19 is installed between the driving member 12 and the connecting member 13. The first lower connection assembly 18 includes a first lower connection plate 20, a first lower bolt 21 and a first lower nut 22. The first lower connection plate 20 is fixed to the outer side of the housing of the driving member 12, the first lower bolt 21 penetrates the first lower connection plate 20 and the supporting member 11, and the first lower nut 22 is threadedly connected to the first lower bolt 21. In this way, due to the detachable connection between the first lower nut 22 and the first lower bolt 21, the detachable connection between the driving member 12 and the supporting member 11 can be achieved.

[0050] The first upper connection assembly 19 includes a first upper connection block 23, a first upper connection plate 24, a pin 25 and a metal belt 26. The first upper connection block 23 is fixed to the output end of the driver 12, the first upper connection is fixed to the bottom of the connection member 13, two first upper connection plates 24 are provided, and the two first upper connections are located on opposite sides of the first upper connection block 23. The pin 25 passes through the first upper connection block 23 and the two first upper connection plates 24, and the metal belt 26 passes through the tail of the pin 25. In this way, due to the detachable connection between the metal belt 26 and the pin 25, the detachable connection between the driver 12 and the connection member 13 can be realized, which is convenient for the disassembly and replacement of the driver 12.

[0051] Further, a second lower connection assembly 27 is installed between the position sensor 16 and the support member 11, and a second upper connection assembly 28 is installed between the position sensor 16 and the connection member 13. The second lower connection assembly 27 includes a second lower connection piece 29, a second lower bolt 30, and a second lower nut 31. The second lower connection piece 29 is fixed to the outer side of the housing of the position sensor 16, the second lower bolt 30 penetrates the second lower connection piece 29 and the support member 11, and the second lower nut 31 is threadedly connected to the second lower bolt 30. In this way, due to the detachable connection between the second lower nut 31 and the second lower bolt 30, a detachable connection between the position sensor 16 and the support member 11 can be achieved.

[0052] The second upper connection assembly 28 includes a second upper nut 32 and a gasket 33. The column at the output end of the position sensor 16 is provided with threads. Two second upper nuts 32 and two gaskets 33 are provided. The two second upper nuts 32 are respectively located at the upper and lower sides of the connecting member 13. The two gaskets 33 are respectively located at the upper and lower sides of the connecting member 13. The second upper nut 32 is threadedly connected to the column at the output end of the position sensor 16, and the gasket 33 is located between the second upper nut 32 and the connecting member 13. In this way, due to the detachable connection between the second upper nut 32 and the column at the output end of the position sensor 16, the detachable connection between the position sensor 16 and the connecting member 13 can be realized, which is convenient for the disassembly and replacement of the position sensor 16.

[0053] Reference Figure 2 Preferably, a plurality of stoppers 34 are installed on the top of the mounting frame 2. In this embodiment, there are three stoppers 34, which are vertically arranged plate-like structures, and the three stoppers 34 are respectively located on the two longitudinal beams 8 at the top and the outermost sides, and on the cross beam 9 at the top and away from the lying frame 1. The arrangement of the three stoppers 34 can accurately place the headrest core at the top position of the mounting frame 2, so that the headrest core is not easily offset.

[0054] Reference Figure 3 Furthermore, a slide groove 35 is provided on the longitudinal beam 8, the length direction of the slide groove 35 is parallel to the length direction of the longitudinal beam 8, a slider 36 is slidably connected in the slide groove 35, and a fixing member 37 is installed between the slider 36 and the support member 11. In this embodiment, the fixing member 37 is a countersunk screw.

[0055] Since the slider 36 is detachably connected to the support member 11 via the fixing member 37, the support member 11 can be easily disassembled and replaced. In addition, the fixing member 37 can be slightly loosened to allow the slider 36 to slide relative to the support member 11, thereby adjusting the front and rear position of the entire support member 11 and facilitating the increase or decrease of the number of detection modules 3.

[0056] Reference Figure 4Furthermore, the cross-sectional area of ​​the slide groove 35 is larger than the cross-sectional area of ​​the slider 36. A spring piece 38 is fixed to the bottom of the slider 36, and the spring piece 38 can cooperate with the bottom of the slide groove 35. Since the spring piece 38 has a certain elasticity, the spring piece 38 can apply a certain thrust to the bottom of the slide groove 35, so that there is a certain friction between the spring piece 38 and the bottom of the slide groove 35, so as to improve the connection stability between the slider 36 and the longitudinal beam 8.

[0057] When ordering a custom lumbar pillow:

[0058] Reference Figure 6 and Figure 7 , the number of detection modules 3 is reduced according to the waist pillow core 39, so that the number of detection modules 3 is five, and the distance between two adjacent detection modules 3 is adaptively adjusted to facilitate the adaptation of the waist pillow core 39 in this embodiment, and the pads 15 of each detection module 3 need to be set to the same length to facilitate the adaptation of the waist pillow core 39 in this embodiment. In addition, the installation frame 2 needs to be installed in the middle position of the lying frame 1, so that when the person lies flat on the lying frame 1, the waist of the human body can correspond to the positions of multiple detection modules 3.

[0059] Since the middle area of ​​the top of the waist pillow core 39 needs to be set to a wave shape with a high middle and low sides in order to fit the curve of the human waist as much as possible to improve the comfort of the human body, this will cause the thickness of the waist pillow core 39 between the bottom of the upper waist detection area 43, the middle waist detection area 44 and the lower waist detection area 45 of the waist pillow core 39 and the top of the corresponding detection area to be inconsistent, which is easy to cause errors in subsequent detection. Therefore, the upper waist detection area 43, the middle waist detection area 44 and the lower waist detection area 45 of the waist pillow core 39 are all set to a step shape, and the bottom height of the middle waist detection area 44 is higher than the bottom height of the lower waist detection area 45 and the upper waist detection area 43. In this way, the thickness of the waist pillow core 39 corresponding to the upper waist detection area 43, the middle waist detection area 44 and the lower waist detection area 45 of the waist pillow core 39 can be kept basically consistent to reduce the error of subsequent detection. In addition, the stepped arrangement of the upper waist detection area 43, the middle waist detection area 44 and the lower waist detection area 45 can also facilitate the subsequent filling work of filling materials of different thicknesses and materials.

[0060] The upper waist detection area 43 includes a seventh step groove 46 and an eighth step groove 47. The length, width and depth of the seventh step groove 46 are 210 mm, 28 mm and 15 mm respectively, and the length, width and depth of the eighth step groove 47 are 210 mm, 28 mm and 25 mm respectively.

[0061] Since the depth of the seventh step groove 46 and the eighth step groove 47 gradually increases, the thickness of the waist pillow core 39 between the bottom of the upper waist detection area 43 and the upper waist support portion 40 can be kept as consistent as possible at different positions to reduce the error of subsequent detection. The seventh step groove 46 and the eighth step groove 47 have the same width in order to adapt to the pads 15 of the same size on the detection modules 3 at different positions.

[0062] Preferably, the length, width and depth of the mid-waist detection area 44 are 210 mm, 28 mm and 30 mm respectively.

[0063] Further, the lower waist detection area 45 includes a tenth step groove 48 and an eleventh step groove 49, the length, width and depth of the tenth step groove 48 are 210mm, 28mm and 20mm respectively, and the length, width and depth of the eleventh step groove 49 are 210mm, 28mm and 10mm respectively. Since the depth of the tenth step groove 48 is less than the depth of the middle waist detection area 44, and the depth of the eleventh step groove 49 is less than the depth of the tenth step groove 48, it is convenient to adapt to the lower waist curve of the human body to improve the accuracy of subsequent detection.

[0064] Since the variation range of the upper waist curve of the human body is greater than that of the lower waist curve, the depth of the seventh step groove 46 is greater than the depth of the eleventh step groove 49 , and the depth of the eighth step groove 47 is greater than the depth of the tenth step groove 48 .

[0065] In this way, the thickness of the waist pillow core 39 corresponding to the upper waist detection area 43, the middle waist detection area 44 and the lower waist detection area 45 of the waist pillow core 39 can be kept basically consistent, so as to reduce the error of subsequent detection.

[0066] It should be noted that, in this embodiment, the number of detection modules 3 needs to be reduced according to the waist pillow core 39, so that the number of detection modules 3 is five, and the distance between two adjacent detection modules 3 is adaptively adjusted to facilitate the adaptation of the waist pillow core 39 in this embodiment, and the cushion blocks 15 of each detection module 3 need to be set to the same length to facilitate the adaptation of the waist pillow core 39 in this embodiment. In addition, in this embodiment, the installation frame 2 needs to be installed in the middle position of the lying frame 1, so that when a person lies flat on the lying frame 1, the waist of the human body can correspond to the positions of multiple detection modules 3.

[0067] The implementation principle of a device for customizing pillows or lumbar pillows in an embodiment of the present application is as follows: detecting multiple filling materials of different initial thicknesses, and drawing a curve diagram between their pressure values ​​and downward pressing thicknesses, and recording the data in a database; placing a headrest core on the detection module 3, and lying on the device in a supine position and in the most comfortable state, with the neck and head of the human body located in the middle of the headrest core; multiple detection modules 3 detect the pressure of multiple areas on the headrest core; adding the values ​​of the pressure sensors 14 corresponding to the multiple detection modules 3 to obtain an average value; and adjusting the column heights of the detection modules 3 so that the values ​​of the pressure sensors 14 corresponding to each detection module 3 are close to the average value, so that all columns are balanced in force; obtaining the column heights and corresponding pressure values ​​of the multiple detection modules 3; selecting filling materials of corresponding materials and initial thicknesses according to the heights and corresponding pressure values ​​of each column; filling the filling materials into the headrest core; and preparing a pillow; a pillow made based on this data better fits the user's neck and head.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
