Description

Technical Field

[0001] This disclosure relates to the field of sleep, and more specifically to a movement and a sleep pillow including the movement. Background Technology

[0002] Currently, there is a type of sleep pillow on the market that uses guided breathing techniques—a natural, clinically proven method—to help relax and calm the user's mind, making it easier to fall asleep and improving sleep quality throughout the night. Guided breathing can evoke the body's natural relaxation response. This guided breathing can help with concentration, promote calmness, reduce stress, and thus make it easier for users to fall asleep.

[0003] A sleep pillow typically consists of a pillow core and a movement mechanism. The movement mechanism has a retractable section. The movement mechanism can expand and contract through this retractable section to undulate in accordance with the user's breathing rhythm, thereby causing the pillow core and the entire sleep pillow to undulate.

[0004] When a user hugs a sleep pillow, they can feel fluctuations in their breathing rhythm. For example, when a user's abdomen or palm touches the air cushion, they will feel the fluctuations created by the expandable parts. However, if the fluctuations are too small, the user may not feel anything. In other words, the amplitude of the fluctuations should be large enough to help the user fall asleep. Currently popular sleep pillows guide the user's breathing based on the inflation and deflation of expandable parts (e.g., air bladders). This inflation-and-deflation approach is insufficient to produce a sufficiently large fluctuation amplitude. Therefore, a new approach is needed to provide a sufficiently large fluctuation amplitude to improve the user experience. Utility Model Content

[0005] The purpose of this disclosure is to provide an improved sleep pillow that uses an eccentric wheel-based mechanical solution to at least address the drawback of insufficient undulation amplitude in existing sleep pillows.

[0006] According to a first aspect of this disclosure, a movement for a sleep pillow is provided, characterized in that it comprises: an eccentric wheel, the edge of which includes an annular gear; a drive mechanism coupled to the annular gear to drive rotation of the eccentric wheel; a driven rod, a first end of which is movably connected to the eccentric wheel and moves with the rotation of the eccentric wheel; a slider movably coupled to a second end of the driven rod; a guide groove extending from the upper surface of the movement into the movement for receiving at least a portion of the slider, and the guide groove for guiding the slider to reciprocate with the movement of the driven rod while limiting lateral movement of the slider; and an actuator covering at least a portion of the upper surface of the movement and connected to the slider to reciprocate with the reciprocating movement of the slider.

[0010] According to one embodiment of this disclosure, the annular member is connected to the movement to movably connect the eccentric wheel to the movement.

[0011] According to one embodiment of this disclosure, the first hollow portion of the annular member includes a column, wherein the column includes a first hole penetrating the column and passing through the center of the disk, and the movement includes a recess, and the eccentric wheel includes a first pin that passes through the first hole and enters the recess to movably connect the eccentric wheel to the movement.

[0012] According to one embodiment of this disclosure, the second end of the driven rod includes a second hole, and the slider includes a third hole penetrating the slider, the second hole and the third hole being movably coupled together by a second pin.

[0013] According to one embodiment of this disclosure, the vertical line of the trajectory of the reciprocating motion of the slider is spaced apart from the center of the eccentric wheel.

[0014] According to one embodiment of this disclosure, the speed of the reciprocating motion of the slider changes non-linearly with time.

[0015] According to one embodiment of this disclosure, the actuator includes a flat plate.

[0016] According to one embodiment of this disclosure, the movement further includes one or more gears located between the drive mechanism and the eccentric wheel for adjusting the rotational speed of the eccentric wheel.

[0017] According to one embodiment of this disclosure, the movement includes a cavity for accommodating at least the eccentric wheel, the drive mechanism, the driven rod, and the slider, and the cavity communicates with the guide groove.

[0018] According to one embodiment of this disclosure, the mechanism further includes: a processor for controlling the drive mechanism; and a power supply unit for supplying power to the processor and the drive mechanism.

[0019] According to one embodiment of this disclosure, the drive mechanism includes a motor.

[0020] According to a second aspect of this disclosure, a sleep pillow is provided, comprising: a movement according to this disclosure; a pillow core for enclosing the movement; and wherein the surface of the pillow core is adapted to reciprocate in accompaniment to the reciprocating motion of the actuator.

[0035] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0036] Figure 1 A side view of a movement according to an exemplary embodiment of the present disclosure is shown. Figure 1 As shown, movement 10 has a box-shaped structure. In other embodiments, movement 10 is implemented as having an elliptical three-dimensional structure. It should be understood that movement 101 can be implemented as any suitable structure and shape.

[0037] In one embodiment of this disclosure, the movement 10 may be made of, for example, rigid plastic (e.g., ABS and PC). Further, the dimensions of the movement 10 are preferably 30cm × 20cm × 5cm. The edges of the movement 10 are flexible and variable, thereby facilitating controlled expansion and contraction.

[0038] The movement 10 has an upper housing 101 and a lower housing 102, which together define a cavity 103. This cavity 103 accommodates multiple components, such as a drive mechanism 120, an eccentric wheel 110, a driven rod 130, and a slider 140. These components are interconnected. The upper housing 101 of the movement 101 has a through-hole guide groove 160. This guide groove 160 extends from the upper surface of the movement 10 into the interior of the movement 10 and guides the reciprocating motion of the slider 140. Figure 1 The slider 140 (which moves up and down reciprocatingly) restricts the lateral movement of the slider 140. A guide groove 160 is configured to communicate with the cavity 103 and accommodate at least a portion of the slider 140. Further, the slider 140 is connected to the actuator 150 via the guide groove 160. Preferably, the actuator 150 is implemented in the form of a flat plate to cover at least a portion of the upper surface of the mechanism 10. Since the actuator 150 is connected to the slider 140, the movement of the slider 140 will in turn drive the movement of the actuator 150. In this disclosure, the actuator 150 and the slider 140 can be connected by any suitable mechanical connection, such as a threaded connection, a pin connection, a snap-fit ​​connection, etc.

[0039] In one embodiment, the flat plate measures 28cm × 18cm × 0.5cm and is preferably made of a suitable material such as rigid plastic or lightweight aluminum alloy. In other embodiments of this disclosure, the actuator 150 can be implemented in various other forms, such as a plate with a curved arc, to better engage with the upper surface of the movement 10, thereby further improving the user's comfort when the sleep pillow vibrates. In one embodiment of this disclosure, the actuator 150 may additionally include a downwardly protruding portion adapted to insert into the guide groove 160 and connect with the slider 140. The connection relationships and motion principles of the various components in the movement 10 will be further explained below with the aid of the accompanying drawings.

[0040] Figure 2 An exploded structural schematic diagram of a mechanical drive system 20 according to an exemplary embodiment of the present disclosure is shown. The mechanical drive system 20 includes components such as an eccentric wheel 210, a drive mechanism 220, a driven rod 230, and a slider 240, and is housed within a movement 10. These components are preferably made of durable materials such as stainless steel or aluminum, but may also be made of common engineering plastics (e.g., PPS, PA, POM).

[0041] The drive mechanism 220 can be implemented as a motor, for example. This can be achieved, for example, by providing a separate motor, or by a motor engaging with one or more gears (see below). Preferably, the motor has a rated voltage of 6V. Further, the drive mechanism 220 is coupled to the eccentric wheel 210, thereby enabling the eccentric wheel 210 to rotate. In one embodiment of this disclosure, one or more gears are provided between the eccentric wheel 210 and the drive mechanism 220. Alternatively, the one or more gears can be located within the drive mechanism 220. Preferably, the gear ratio provided by the one or more gears is between 1:2 and 1:10 to ensure that the eccentric wheel 210 can rotate at the desired rotational speed. In one embodiment of this disclosure, the drive mechanism 220 is connected to gear 202. The edge of the eccentric wheel 210 includes a ring gear. Thus, the drive mechanism 220 is tightly coupled to the ring gear via gear 202, thereby reliably converting the axial motion output by the drive mechanism 220 into the rotational motion of the eccentric wheel 210.

[0042] See Figure 2 The driven rod 230 has holes 207 and 208 at its upper and lower ends, respectively. In one embodiment of this disclosure, the driven rod 230 is made of lightweight carbon fiber composite material. The slider 240 is preferably configured as a cylindrical structure. In one embodiment of this disclosure, the slider 240 is made of engineering plastic (such as POM), with a length of 30 mm, an outer diameter of 20 mm, and a height of 10 mm. The lower end of the slider 240 has a hollow structure to accommodate the upper end of the driven rod 230. The slider 240 has a hole 209 penetrating through the slider 240, and the driven rod 230 and the slider 240 can be movably coupled together by a pin 206 passing through the hole 209 and the hole 207 of the driven rod 230. Preferably, the driven rod 230 is configured as narrow at the top and wide at the bottom to maintain the stability of the movement. In one example of this disclosure, the upper end of the slider 240 is configured as a threaded structure for connecting with... Figure 1 The actuator 150 is fixedly connected to the slider 240. The actuator 150 has a central hole with a corresponding threaded structure to match the threaded structure at the upper end of the slider 240. In this way, the slider 240 is fixedly connected to the actuator 150.

[0043] Continue to refer to Figure 2The eccentric wheel 210 further includes a disk 211, the edge of which includes the aforementioned annular gear for coupling with the gear 202. The center of the disk 211 is the rotation center of the eccentric wheel 211, i.e., the location of the hole 213. Further, the disk 211 has a hollow portion (not shown) that matches and engages with the annular member 212. Specifically, an annular member 212 is provided on the disk 211, protruding relative to the disk 211. The center of the annular member 212 is not aligned with the center of the disk 211, and the radius of the annular member 212 is smaller than the radius of the disk 211, thus creating an eccentric rotational effect. Further, the position of the rotation center of the eccentric wheel 210 and the disk 211 (i.e., the position of the hole corresponding to reference numeral 213) is located within the annular member 212. The hollow portion of the annular member 212 includes a column with a hole 213 penetrating through it. The location of the hole 213 is also the rotation center of the disk 211 (i.e., the center of the disk 211 and the eccentric wheel 210). In one example of this disclosure, the pin 214 is inserted through the hole 213 into a corresponding position (e.g., a recess) on the movement to movably connect the eccentric wheel 210 to the movement. Further, the annular member 212 is adapted to be inserted into the hole 208 of the driven rod 230, thereby being nested within the hole 208, thus movably connecting the eccentric wheel 210 to the driven rod 230. Therefore, the eccentric wheel 210, the drive mechanism 220, the driven rod 230, the slider 240, and... Figure 1 The actuators 150 are movably connected together. In one example of this disclosure, the eccentric wheel 210 may be made of high-strength aluminum alloy or rigid plastic.

[0044] Figure 3 A schematic diagram of the overall structure of a mechanical drive system 20 according to an exemplary embodiment of the present disclosure is shown. For example... Figure 3 As shown, Figure 2 The various components described herein have been assembled together. During operation, the axial movement of the drive mechanism 220 will drive the axial movement of the gear 202. Since the gear 202 is coupled to the ring gear of the eccentric wheel 210, the axial movement of the drive mechanism 220 will cause the eccentric wheel 210 to rotate around its center 215. Furthermore, the rotation of the eccentric wheel 210 will drive the movement of the driven rod 230. Finally, the movement of the driven rod 230 will drive the movement of the slider 240 and the actuator 150 connected to the slider 240. Since the slider 240 is constrained by the guide groove 160, the slider 240 will... Figure 1 The guide groove moves back and forth within 160 degrees. Figure 1The slider 240 (which moves up and down in a reciprocating motion) is limited by the guide groove 160, thereby better maintaining the reciprocating motion of the slider 240 and the actuator 150. Thus, the axial motion output by the drive mechanism 220 is ultimately converted into the reciprocating motion of the slider 240, and thus into the reciprocating motion of the actuator 150.

[0045] In actual operation, the drive mechanism 220 drives the eccentric wheel 210 to rotate at a stable angular velocity ω. This angular velocity ω is related to the rotational speed n of the drive mechanism, and the relationship between the two is ω = 2πn / 60. In one example of this disclosure, when the eccentric wheel 210 completes one revolution, the slider 240 and the actuator 150 will also complete one reciprocating motion. Figure 1 and Figure 2 (The middle part is the reciprocating motion). The time for the eccentric wheel 210 to rotate once and the time for the slider 240 and the actuator 150 to complete one reciprocating motion are T = 2π / ω.

[0046] Furthermore, such as Figure 3 As shown, the dashed line a is the vertical line of the sliding trajectory of the slider 240. The distance between this vertical line a and the rotation center 215 of the eccentric wheel 210 is e, which is the offset. Preferably, this offset e is 25 mm. Furthermore, Figure 3 In this context, L represents the length of the driven rod 230. In one example of this disclosure, this length is defined as the distance between the connection point of the driven rod 230 and the slider and the connection point of the driven rod 230 and the eccentric wheel. Preferably, this length L is 42.5 mm. Furthermore, the eccentricity r of the eccentric wheel 210 is preferably 15 mm, and its diameter is 50 mm.

[0047] Therefore, the time-varying stroke displacement x(t) of slider 240 can be determined by the following formula 1, where θ(t)=ω*t.

[0048]

[0049] Figure 4 and Figure 5 The scenarios are shown when the driven rod 230 is at its highest and lowest points, respectively. Figure 4 and Figure 5 As shown by the arrow in the image, Figure 4 and Figure 5 The right side shows an enlarged schematic diagram of the rotation center O of the eccentric wheel 210. For example... Figure 4 As shown, B1 represents the line connecting the rotation center O of the eccentric wheel 210 and the connection center between the driven rod 230 and the eccentric wheel 210, and B2 represents a line parallel to the slider trajectory. The angle between B1 and B2 is Θ1. Figure 5As shown, C1 represents the line connecting the rotation center O of the eccentric wheel 210 and the connection center between the driven rod 230 and the eccentric wheel 210, and C2 represents a line parallel to the slider trajectory. The angle between C1 and C2 is Θ2. Under Θ1 and Θ2 conditions, the maximum displacement X of the slider... max and minimum displacement X min They are respectively:

[0050]

[0051] Therefore, the fluctuation amplitude (i.e., the amplitude of the reciprocating motion) of the slider and the actuator is h = X. max -X min .

[0052] Figure 6 A schematic diagram of the motion of a mechanical drive system 20 according to an embodiment of the present disclosure is shown. As described above, the slider 240 in the mechanical drive system 20 reciprocates under the drive mechanism 220. Figure 6 On the left side, slider 240 is located at the highest point of the reciprocating motion (i.e., the maximum displacement X). max ).exist Figure 6 On the right side, slider 240 is located at the lowest point of the reciprocating motion (i.e., the minimum displacement X). min ). Figure 6 The intermediate diagram shows that the slider 240 is in a certain intermediate position during reciprocating motion.

[0053] Figure 7 A schematic diagram of the movement of a slider according to an embodiment of the present disclosure is shown. Figure 7 In this diagram, the vertical axis represents the height of the slider, while the horizontal axis represents time. The values ​​on the vertical axis can be calculated, for example, using Formula 1 as described earlier. As mentioned earlier, due to the constraints of the guide groove, in... Figure 1 and Figure 6 The slider in the image moves in a reciprocating up-and-down motion. However, as... Figure 7 As shown, the speed of this reciprocating motion is non-linear. Therefore, combining Equation 1 and the relevant figures, the frequency and amplitude of the up-and-down undulations of the sleep pillow surface can be adjusted, for example, by changing the rotational speed of the drive mechanism and / or the eccentricity of the eccentric wheel, ultimately achieving the goal of meeting the user's personalized needs. This also means Figure 7 The resulting guide curve allows the up-and-down movement of the pillow surface caused by the slider and actuator to more effectively simulate the user's natural breathing rhythm, helping the user relax and improve sleep quality. In one example of this disclosure, the rotational speed of the drive mechanism and / or the gear settings can be adaptively adjusted accordingly to achieve the user's breathing rate (e.g., 0.5 Hz).

[0054] Figure 8A first schematic diagram of a movement according to an exemplary embodiment of the present disclosure is shown. Figure 9 A second schematic diagram of a movement according to an exemplary embodiment of the present disclosure is shown. Figure 8 In the movement 80, the actuator 850 covers at least a portion of the upper surface of the movement 80. And... Figure 9 In the middle, the actuator 950 of the movement 90 is lifted by the mechanical drive system described above.

[0055] Figure 10 An exploded structural diagram of a sleep pillow according to an exemplary embodiment of the present disclosure is shown. The sleep pillow includes a pillow core 1000, which is composed of an upper shell 1001 and a lower shell 1002. The upper shell 1001 and the lower shell 1002 together define a cavity for accommodating the movement 10. In one embodiment of the present disclosure, the pillow core 1000 may be made of a soft, high-quality memory foam material. The overall dimensions of the pillow core 1000 may be approximately 50cm × 30cm × 10cm. The Shore hardness of the memory foam material is preferably between 40 and 50 degrees.

[0056] The movement 10 includes an upper housing 101 and a lower housing 102, which together define a cavity 885 to accommodate various components housed within the movement 10. These components include the aforementioned mechanical drive system 20, and preferably also include a processor 870 and a power supply unit 880. The power supply unit 880 is preferably implemented as a battery to power the processor 870 and the drive mechanism. The processor 870 is preferably implemented as a PCBA circuit board 870. This PCBA circuit board 870 integrates a suitable processor unit such as a microprocessor and MOS for sending drive information, such as control signals, to the drive mechanism in the mechanical drive system 200. As previously described, the slider in the mechanical drive system 20 is adapted to insert upward into a guide slot in the movement 10, thereby connecting with the actuator 850. In one embodiment of this disclosure, the processor 870 sends a PWM signal to the drive mechanism to adjust the rotational frequency of the drive mechanism (and, if necessary, can cooperate with one or more gears and drive mechanisms described above), controlling the frequency of the reciprocating motion of the slider of the mechanical drive system and the actuator 850, so that the frequency is adapted to the user's breathing rate. Furthermore, the sleep pillow also includes a control unit 890, which is embedded in a recess on the outer side of the junction of the upper housing 1001 and the lower housing 1002 of the sleep pillow, and is adapted to connect to the processor 870, thereby facilitating the user to adjust the rotational frequency of the drive mechanism and, consequently, the reciprocating motion frequency of the actuator 850 from outside the sleep pillow by controlling the processor 870, so that the frequency matches the user's breathing rate. The control unit 890 may be, for example, an external button, including, for example, a power button for the sleep pillow, a button for adjusting the rotational frequency of the drive mechanism and thus the linear reciprocating motion frequency of the actuator, or other suitable buttons.

[0057] Figure 11 Another exploded structural diagram of a sleep pillow according to an exemplary embodiment of the present disclosure is shown. Figure 11 As shown, the movement 10 has been assembled and is adapted to be housed within the cavity defined by the upper housing 1001 and lower housing 1002 of the pillow core 1000 of the sleep pillow. The upper housing 1001 and lower housing 1002 can be adapted to be connected together in any manner suitable in the art. Once the upper housing 1001 and lower housing 1002 are integrally connected, the sleep pillow will be shaped to suit user use.

[0058] In one example of this disclosure, during actual assembly, the drive mechanism is first placed into the core and secured. Then, an eccentric wheel is mounted to the output of the drive system, ensuring a tight connection. One end of the driven rod is connected to the eccentric wheel, and the other end to the slider. The slider is fitted into the guide groove, ensuring it can move freely along the groove. The slider is connected to the actuator. The actuator is placed on the outer surface of the core and in contact with the pillow core. The remaining components, such as the PCBA circuit board, power supply unit, etc., are installed in the pillow core cavity, ensuring proper connection of each component. Finally, the entire core is encapsulated within the pillow core, ensuring smooth operation of the mechanical and electrical components. During operation, the drive mechanism (e.g., a motor) rotates the eccentric wheel at a specified angular velocity ω. As the eccentric wheel rotates, the driven rod transmits motion to the slider, causing it to move back and forth linearly along the guide groove. The slider's motion is then transmitted to the actuator. The surface of the pillow core is adapted to reciprocate in sync with the actuator's reciprocating motion, thereby causing the sleep pillow to rise or fall.
