Description

Technical Field

[0001] This utility model relates to an intelligent adjustable ergonomic pillow, and belongs to the field of pillow technology. Background Technology

[0002] Pillows are an indispensable bedding item in people's daily lives, and using pillows can help people get a good night's sleep.

[0003] Most existing pillows have a fixed structure and their height is not adjustable. A single pillow typically cannot suit the needs of different users, and its functionality is relatively limited. Existing technologies offer some solutions for adjustable pillows, such as using a height adjustment device to inflate or deflate airbags to adjust the pillow's height. However, in these existing technologies, the airbag adjustment is only located at the head-neck connection point; the neck support position cannot be adjusted. Since everyone's neck height is different, the rise and fall of the head position during height adjustment causes significant changes in the head-neck curve. Therefore, this structure is difficult to meet the practical needs of different users, and its functionality is relatively limited. Therefore, this paper proposes an intelligent adjustable ergonomic pillow to solve the problems existing in current technologies. Utility Model Content

[0025] See Figures 1-7As shown, the technical solution adopted in this specific embodiment is as follows: It includes an elastic pillowcase 1, a pillow core 2 inside the elastic pillowcase 1, and a lifting mechanism 3 inside the pillow core 2. In this embodiment, an integrated lifting mechanism is set inside the pillow core. The existing smart pillows mainly adjust the head position, which is suitable for the same user to adjust the pillow height in different sleeping positions. However, since the neck height is not adjustable, the experience is not good when different users use it. Therefore, this embodiment sets an integrated lifting structure to adjust the head and neck positions. The pillow core itself adopts an ergonomic wave-shaped structure design and uses high-elastic memory foam material. The pillow can also adopt a traditional shallow arc-shaped surface design, allowing users to choose according to their preferences. Generally, a wave-shaped structure provides better neck support, and those with poor sleep can choose this type of pillow core. Since this type of structure is a conventional design, this implementation does not impose too many restrictions. When different users adjust the pillow height through the lifting mechanism, the head and neck are raised simultaneously within a small range because the curves of the head and neck remain basically unchanged. Only the curves of the neck and body change, which is more in line with ergonomic design and can improve sleep quality. In contrast, the traditional structure raises the head but not the neck, which can cause neck discomfort and affect sleep quality.

[0026] More specifically, the lifting mechanism 3 is equipped with a heating plate 4 which is electrically connected to the control main board 8 inside the lifting mechanism 3. To enrich the functionality of the smart pillow, this embodiment also includes a heat therapy function, which is to heat the pillow by means of the heating plate. The temperature generated by the heating plate can be conducted to the user through the pillow core and elastic pillowcase to provide heat therapy for the head and neck. The heating plate is divided into multiple individually heated areas, such as multiple independently controlled electric heating wires or other heating elements. By setting the time and temperature or manually adjusting the temperature, the heat therapy effect that meets the user's needs can be obtained.

[0027] The pillow core 2 is equipped with a matrix-style temperature measuring area 211, within which several flexible NTC thermistors 213 are installed. These flexible NTC thermistors 213 are electrically connected to the control motherboard 8 via a serpentine conductive circuit. The temperature measuring area 211 also includes a matrix of sensor mounting slots 212 for mounting the flexible NTC thermistors 213. The surface of the sensor mounting slots 212 is flush with the detection surface of the flexible NTC thermistors 213. In this embodiment, a detection circuit is also included. By installing flexible NTC thermistors within the matrix-style temperature measuring area, the user's body surface temperature can be detected. The detection data can be stored in the control motherboard or read and saved by an external device via a data transmission module. This allows for monitoring of the user's body surface temperature changes during sleep, facilitating the monitoring of the user's health. Continuous monitoring provides a complete body temperature database. Due to the matrix arrangement structure, the system can effectively monitor the user's body surface temperature changes during sleep. Temperature data is collected from different contact points, such as head and neck temperatures, facilitating zoned temperature control. It should be noted that the heating plate has corresponding heating areas for different horizontal arrays of flexible NTC thermistors. That is, the heating plate has multiple heating zones, each with individual temperature control. In use, the intelligent mode can be directly used, automatically setting the heating temperature based on the collected temperatures of different areas, thus providing users with precise and intelligent thermotherapy effects. Taking this embodiment as an example, there are four rows and eight columns of flexible NTC thermistors, resulting in four heating areas. The edge areas are for neck heating, and one heating area can be used for this purpose. The other three areas heat the head. If the user moves closer to the center, the two edge areas corresponding to the neck are heated, while the other two areas heat the head. This method can be performed in intelligent mode, where the sensing unit automatically senses the temperature and performs specific control based on the temperature, achieving intelligent heating control.

[0028] More specifically, the pillow core 2 includes an upper pillow core 21 and a lower pillow core 22. Both the upper pillow core 21 and the lower pillow core 22 have mating grooves 221 that match the lifting mechanism 3. The surface of the upper pillow core 21 is a temperature-regulating buffer layer 214, into which wax-based composite phase change microcapsules 215 are uniformly filled. The main bodies of the upper pillow core 21 and the lower pillow core 22 are made of high-elasticity memory foam. In this embodiment, the pillow core is also a split structure, which can effectively cooperate with the lifting mechanism for lifting. Furthermore, the high-elasticity memory foam material used in the pillow core not only has good elasticity but also good resilience, is not easily deformed, and provides good support for the head and neck. More importantly, a temperature-regulating buffer layer is provided on the upper pillow core, into which wax-based composite phase change material is filled with nano-sized... The wax-based composite phase change microcapsules are encapsulated within porous materials and uniformly distributed within the temperature-regulating buffer layer. This allows for temperature buffering, with each gram of paraffin absorbing / releasing approximately 200 J / g of heat, significantly buffering temperature fluctuations. Specifically, when the ambient temperature is higher than the wax-based composite phase change microcapsules, the microcapsules absorb external heat to cool the pillow. Conversely, when the ambient temperature is lower than the microcapsules, they release heat to automatically heat the pillow, preventing excessive temperature differences between the pillow surface and the head or neck, thus bringing the temperature closer to the body surface and providing a more comfortable experience. Due to the relatively small temperature buffer range, the heating plate is activated for heat therapy when needed, while the temperature-regulating buffer layer primarily provides automatic temperature regulation during daily use without requiring manual control.

[0029] More specifically, a remote control 5 is provided on one side of the lifting mechanism 3 and is electrically connected to the control motherboard 8. The control motherboard 8 is equipped with an STM32L4 microcontroller, a storage module, and a power module. In this embodiment, the pillow's height adjustment and intelligent temperature control are achieved through the STM32L4 microcontroller. All temperature data collected from users are stored in the storage module. The STM32L4 microcontroller compares the collected data and performs intelligent output control. Based on the real-time temperature feedback, it associates the heating areas to achieve zoned heating, which is suitable for the different temperature needs of the head and neck, providing a more comfortable experience.

[0030] More specifically, the lifting mechanism 3 includes a supporting top plate 31 and a bottom plate 32. The bottom plate 32 is provided with a first lifting platform mechanism 6 and a second lifting platform mechanism 7 connected to the supporting top plate 31. The first lifting platform mechanism 6 and the second lifting platform mechanism 7 have the same structure. The lifting mechanism has a split structure, which is provided with two lifting platforms. The two lifting platforms are symmetrically arranged to support the supporting top plate and control its lifting speed. The lifting speed is the same.

[0031] More specifically, the first lifting platform mechanism 6 includes a lifting top plate 61, a lifting bottom plate 62, a folding lifting bracket 63, and a lifting motor 64. The folding lifting bracket 63 and the lifting motor 64 are mounted on the lifting bottom plate 62, and the lifting motor 64 is connected to the folding lifting bracket 63 in a transmission connection. The top of the folding lifting bracket 63 is connected to the lifting top plate 61. In this embodiment, the lifting motor drives and controls the folding lifting bracket to achieve the adjustment of the pillow height. The lifting motor is a servo motor, which provides more precise adjustment and control of the lifting.

[0032] More specifically, the folding lifting bracket 63 includes four intersecting lifting support rods 631 and three transverse support rods 632 positioned between the lifting support rods 631. The three transverse support rods 632 are positioned away from the lifting motor 64 and are all movably connected to the lifting support rods 631. Guide plates are provided on both sides of the facing surfaces of the lifting top plate 61 and the lifting bottom plate 62. Guide rail grooves 621 are provided in the guide plates. The guide rail grooves 621 and the transverse support rods 632 cooperate with the two ends of the driven screw. In this embodiment, the specific lifting method of the lifting mechanism is as follows: the drive motor drives the lifting support rods to rotate, and the transverse support rods are constrained by the guide rail grooves, so that the transverse support rods can only move within the guide rail grooves, thereby driving the lifting support rods to rise and fall, and then driving the lifting top plate to rise and fall. The overall structure is simple, the lifting effect is good, and the height adjustment is more precise under the drive of the servo motor.

[0033] More specifically, a transmission seat 65 is provided inside the lifting support rod 631 on one side of the bottom of the folding lifting bracket 63. A driven lead screw is provided inside the transmission seat 65, and a bearing seat 66 is provided outside the transmission seat 65. The bearing seat 66 is connected to the lifting motor 64 and supports the output shaft of the lifting motor 64. The output shaft of the lifting motor 64 is a lead screw. The part of the output shaft passing through the bearing seat 66 is a smooth surface, and the transmission part that contacts the driven lead screw of the transmission seat 65 is a threaded surface. The end of the output shaft is also a smooth surface, and a support seat 67 with a bearing is provided at the end. The support seat 67 is fixed on the lifting base plate 62. In this embodiment, the drive motor adopts lead screw transmission. The output shaft is provided with a thread in the middle to cooperate with the driven lead screw, driving the lifting support rod to rotate and lift. The bearing seat and the support seat support the output shaft and cooperate with its rotation, making the transmission more stable and vibration-free, ensuring the smoothness of lifting.

[0034] The working principle of this utility model is as follows: The upper pillow core 21 can adopt an ergonomic wave-shaped structure. When the user lies on it, the neck and head present a curved posture on the pillow core. Different users require different pillow heights. The pillow is at its lowest initial height. When the height needs to be adjusted, simply press the switch and select the rise function. The lifting motor 64 is a servo motor, which can precisely control the rotation speed, thereby accurately controlling the lifting height. The lifting top plate 61 pushes the upper pillow core 21 to rise, thus realizing the height adjustment. Since the overall size of the lifting top plate 61 is smaller than the size of the pillow core 2, there will be no large opening at the edge of the pillow core when the height is raised, and it will still be restrained by the elastic pillowcase 1, ensuring comfort. Each user can set a memory state after the height is adjusted via remote control, such as the flat lying state as memory 1. The side-lying position is memory 2, and the pillow can be easily adjusted to the most suitable height by selecting the corresponding memory state. During use, the pillow also has a temperature regulation function. First, the surface of the upper pillow core 21 is a temperature regulation buffer layer 214. This layer adopts a structure filled with wax-based composite phase change microcapsules 215. The wax-based composite phase change material is a passive heat storage and heat release material with a melting point of 28-32 degrees Celsius, which is the most suitable temperature for sleep. When the temperature is high, it absorbs and stores heat to achieve cooling, and when the temperature is low, it releases heat to achieve heating. When the user lies on the pillow, the temperature will be automatically adjusted. If a higher temperature is needed, the heating function will be turned on. The heating time and heating temperature can be set by remote control, and the heating plate 4 will start to heat up, heating the neck and back of the head to achieve the purpose of heat therapy, thereby obtaining a better user experience.
