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 a mechanical drive system to provide adjustable breathing simulation with significant fluctuations, thereby eliminating at least the aforementioned disadvantages of the prior art.

[0006] According to a first aspect of this disclosure, a movement for a sleep pillow is provided, comprising: a cam; a drive mechanism coupled to the cam to drive the cam to rotate; a return spring; a follower assembly located above and in contact with the cam, at least a portion of the follower assembly being surrounded by the return spring, and the follower assembly being adapted to reciprocate under the action of the cam and the return spring; and an actuator covering at least a portion of an upper surface of the movement and connected to the follower assembly to reciprocate in accordance with the reciprocating motion of the follower assembly.

[0007] According to one embodiment of this disclosure, the driven assembly further includes: a roller that contacts the cam; a slider that is connected to the actuator; and a driven rod, one end of which is connected to the roller and the other end of which is connected to the slider; wherein the return spring surrounds at least a portion of the driven rod.

[0008] According to one embodiment of this disclosure, the rotation direction of the roller and the rotation direction of the cam are located in the same plane.

[0009] According to one embodiment of this disclosure, the end of the driven rod connected to the roller includes a first limiting portion to restrict the downward displacement of the return spring.

[0010] According to one embodiment of this disclosure, one end of the roller and one end of the driven rod are connected together by a first pin; and / or the other end of the slider and the driven rod are connected together by a second pin.

[0011] According to one embodiment of this disclosure, the movement includes a cavity for accommodating at least the drive mechanism, the cam, the driven assembly, and the return spring.

[0012] According to one embodiment of this disclosure, the cavity includes a second limiting portion to restrict the upward displacement of the reset spring.

[0013] According to one embodiment of the present disclosure, the cam includes a body and a connecting portion, wherein the connecting portion is connected to the drive mechanism, and the body has an asymmetrical profile.

[0014] According to one embodiment of this disclosure, the distance between the rotation center of the body and the farthest end of the body's outline is a first distance, and the distance between the rotation center of the body and the nearest end of the body's outline is a second distance, the difference between the first distance and the second distance being between 20 and 40 millimeters.

[0015] 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.

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

[0017] According to one embodiment of this disclosure, the transmission ratio of the one or more gears is between 1:2 and 1:10.

[0018] According to one embodiment of this disclosure, the movement includes a guide groove extending from the upper surface of the movement into the interior of the movement for receiving at least a portion of the slider, and the guide groove is used to guide the reciprocating motion of the slider and restrict the lateral movement of the slider.

[0019] According to one embodiment of this disclosure, the actuator includes a flat plate.

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

[0021] This disclosure replaces the traditional air pump-driven design with a cam-driven mechanical drive system, ensuring that the adjustable reciprocating motion of the sleep pillow precisely matches the user's breathing fluctuations. The rotating cam pushes a driven component, which in turn moves an actuator plate up and down, causing the sleep pillow to expand and contract similarly to breathing. Simultaneously, the cam profile design ensures smooth and controllable amplitude of the reciprocating motion. Furthermore, the amplitude and frequency of the reciprocating motion can be adjusted by modifying the cam shape and the speed of the drive mechanism, thus achieving targeted adjustments to meet the user's needs. This sleep pillow provides more effective and natural breathing simulation, thereby improving the user's sleep quality.

[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 example embodiment of the present disclosure is shown. Figure 1 As shown, the movement 100 has a box-shaped structure. In other embodiments, the movement 100 is implemented as having an elliptical three-dimensional structure. It should be understood that the movement 100 can be implemented as any suitable structure and shape.

[0037] In one embodiment of this disclosure, the movement 100 may be made of, for example, rigid plastic (e.g., ABS and PC). Further, the dimensions of the movement 100 are preferably 30cm × 20cm × 5cm. The edges of the movement 100 are flexible and variable, thereby facilitating controlled expansion and contraction.

[0038] The movement 100 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 cam 110, a drive mechanism 120, a driven assembly 130, and a return spring 140 surrounding at least a portion of the driven assembly 130. These components are interconnected. The upper housing 101 of the movement 10 has a through guide groove 190. This guide groove 190 extends from the upper surface of the movement 100 toward the interior of the movement 100 and guides the reciprocating motion of the driven assembly 140. Figure 1 The actuator 140 (which undergoes a reciprocating motion) restricts the lateral movement of at least a portion of the driven component 140. The guide groove 140 is configured to communicate with the cavity 103. Further, the driven component 130 is connected to the actuator 150 via the guide groove 160. Preferably, the actuator 150 is implemented as a flat plate to cover at least a portion of the upper surface of the movement 100. Since the actuator 150 is connected to the driven component 130, the movement of the driven component 130 will in turn drive the movement of the actuator 150. In this disclosure, the actuator 150 and the driven component 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 100, 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 140 and connect with the driven component 130. The connection relationships and motion principles of the various components in the movement 100 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 according to an exemplary embodiment of the present disclosure is shown.

[0041] The mechanical drive system 200 includes a cam 210, a drive mechanism 220, a driven assembly 230, and a return spring 240, and is adapted to be housed within a movement 100. 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).

[0042] The drive mechanism 220 can be implemented as a motor, for example. In one embodiment of this disclosure, the motor speed is configured such that the cam 210 rotates at 30 revolutions per minute. This can be achieved, for example, by using a separate motor, or by the 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 cam 210, thereby enabling the cam 210 to rotate.

[0043] In one embodiment of this disclosure, one or more gears (not shown) are provided between the cam 210 and the drive mechanism 220. Alternatively, the one or more gears may be located within the drive mechanism 220. Preferably, the one or more gears provide a gear ratio between 1:2 and 1:10 to ensure that the cam 210 can rotate at the desired rotational speed.

[0044] Further, see Figure 2 The driven assembly 230 further includes a driven rod 231, a roller 232, and a slider 233. Holes 234 and 235 are respectively provided at both ends of the driven rod 231. The lower end of the driven rod 231 is hollow to accommodate the roller 232. The center of the roller 232 is also hollow. A pin 236 passes through the hole 234 at the lower end of the driven rod 231 and the center of the roller 232, thereby connecting the roller 232 to the driven rod 231. The roller 232 is adapted to rotate around the pin 236 and maintain contact with the cam 210. The rotation direction of the roller 232 is in the same plane as the rotation direction of the cam 210. The slider 233 is preferably configured as a cylindrical structure, and the height of the slider 240 is preferably 5 cm. The lower end of the slider 240 has a hollow structure to accommodate the upper end of the driven rod 231. The slider 233 has a hole 238 penetrating through it. By passing a pin 237 through a hole 238 and a hole 235 in the driven rod 231, the driven rod 231 can be movably coupled to the slider 233. In one example of this disclosure, the upper end of the slider 233 can be configured with a threaded structure for use with... Figure 1 The actuator 150 is fixedly connected to the slider 233. The actuator 150 has a central hole with a corresponding threaded structure to match the threaded structure at the upper end of the slider 233. In this way, the slider 233 is fixedly connected to the actuator 150.

[0045] Therefore, the rotational motion of the cam 210 will cause the reciprocating motion of the driven rod 231 through the roller 232 in contact with it. Consequently, the slider 233 located at the upper end of the driven rod 231 will also reciprocate, thereby driving the reciprocating motion of the actuator 150 connected to it. Further, as... Figure 1As shown, slider 233 will reciprocate within guide groove 190, and the lateral displacement of slider 233 is limited by guide groove 190, thereby better maintaining the reciprocating motion of slider 233 and actuator 150. In one example of this disclosure, the initial position of follower 231 is the position when roller 232 of follower 231 is at its lowest point. Return spring 240 is used to surround at least a portion of follower 231, so that after follower 231 moves upward from its initial position, it can retract, i.e., move downward, as cam 210 rotates. Preferably, in one embodiment of this disclosure, one end of follower 231 connected to roller 232 includes a first limiting portion to limit the downward displacement of return spring 240. Thus, return spring 240 can drive follower 231 back to its initial position through the first limiting portion.

[0046] Figure 3 A schematic diagram of the overall structure of a cam according to an exemplary embodiment of the present disclosure is shown. Figure 4 A schematic cross-sectional view of the body of a cam according to an exemplary embodiment of the present disclosure is shown. In the following, it will be combined with... Figure 3 and Figure 4 The cam of this disclosure is described below. The cam 210 includes a body 211 and a connecting portion 212. The connecting portion 212 is hollow and adapted to connect with the body 211 and with a drive mechanism 220. In one embodiment of this disclosure, the connecting portion 212 passes through the body 211 to increase stability during rotation.

[0047] like Figure 3 As shown, the main body 211 has an asymmetrical profile. Preferably, as... Figure 4 As shown, the cross-section of the main body 211 is asymmetrical. Specifically, Figure 4 Point O in the diagram is the center of rotation of the main body 211. For example... Figure 4 As shown, the main body 211 can rotate around point O in the D direction. R indicates the distance from the rotation center O to the farthest end of the cam profile (i.e., the farthest distance), and r indicates the distance from the rotation center O to the nearest end of the cam profile (i.e., the closest distance). The farthest end can correspond to the peak of the user's breathing curve, while the closest end can correspond to the trough of the user's breathing curve. Preferably, r can be in the range of 5 to 50 mm, or it can be larger. For example, if the volume of the mechanism 100 is large, the value of r can also be larger. Rr, that is, the difference between the farthest distance and the closest distance, is preferably between 20 and 40 mm. In one embodiment of this disclosure, the distance R+r, that is, the length of the cam 211, can be set between 2 cm and 3.5 cm, thereby achieving a reciprocating motion amplitude that matches the user's breathing.

[0048] On the other hand, due to the different values ​​of R and r, the profile of cam 211 consists of two parts. For example...Figure 4 As shown, the dashed lines divide the cam 211 into a first part A and a second part B. In one embodiment, the contours of these two parts are not equal. The contour of the first part A is slightly convex (e.g., ...). Figure 4 The longer section of the outline), while the outline of the second part B is relatively flat (as shown in the image). Figure 5 (The shorter segment of the outline). In one embodiment of this disclosure, the length difference between the outline of the first part A and the outline of the second part B is between 10% and 30% of the length of the outline of the first part A. The outline of the first part A serves to guide the inhalation phase of the user's breathing process, while the outline of the second part B serves to guide the exhalation phase of the user's breathing process. In an example of this disclosure, a circular outline segment with an angle between 5 and 15 degrees is provided at the farthest and nearest ends, respectively, to guide the user's switching between exhalation and inhalation.

[0049] Figure 6 A schematic diagram of the first motion of a mechanical drive system according to an exemplary embodiment of the present disclosure is shown. Figure 5 A schematic diagram of the second motion of a mechanical drive system according to an exemplary embodiment of the present disclosure is shown. Figure 6 In the middle, cam 510 rotates to its highest point, while... Figure 5 In the diagram, cam 610 has rotated to the upper left position. Direction D1 exemplarily illustrates the rotation direction of cam 610.

[0050] The following text will use Figure 6 and Figure 5 The motion of the mechanical drive system is described. For example... Figure 5 As shown, the mechanical drive system 500 includes a cam 510, a drive mechanism 520, a follower rod 550, a roller 560 connected to the follower rod 550, a return spring 540 surrounding at least a portion of the follower rod 550, and a slider 570 connected to the follower rod 550. The roller 560 remains in contact with the cam 510. The plane in which the roller 560 can rotate is substantially the same as the plane in which the cam 510 can rotate, thereby improving the resistance to jamming of the cam movement. In other words, by providing the roller 560, the cam 510 can better drive the reciprocating motion of the follower rod 550. Figure 6 and Figure 6 (The middle part represents reciprocating motion up and down). For example... Figure 6 As shown, when the drive mechanism 620 drives its coupled cam 610, the cam 610 will rotate accordingly (e.g., by means of rotation). Figure 6(In the D1 direction). The rotation of cam 610 means that its height position will change up and down. Since roller 660 is in contact with cam 610, the rotation of cam 610 also drives roller 660 to rotate, which in turn causes follower rod 650 to reciprocate, and finally causes slider 670 to reciprocate. Here, return spring 640 allows follower rod 650 to retract, that is, to move downward, after moving upward, as cam 610 rotates. Therefore, when cam 610 completes one rotation, follower rod 650 can also complete one cycle of reciprocating motion (in the D1 direction). Figure 7 (The middle part is a reciprocating motion).

[0051] Figure 7 An enlarged schematic diagram of the components of a movement according to an exemplary embodiment of the present disclosure is shown. Figure 8 As shown in the enlarged view above, the mechanical drive system 700 includes a cam 710, a follower rod 750, a roller 760 connected to the follower rod 750, a return spring 740 surrounding at least a portion of the follower rod 750, and a slider 770 connected to the follower rod 750. These components are preferably housed within a cavity 703 of the movement. A first limiting portion is included at the end of the follower rod 750 near the roller 760 to limit the downward displacement of the return spring 740. The cavity 703 includes a second limiting portion 780 to limit the upward displacement of the return spring 740. Therefore, by providing the first and second limiting portions 780, the overall displacement of the return spring 740 can be limited, thereby allowing the return spring 740 to better cooperate with the cam 710 so that the follower rod 750 and the slider 770 can reciprocate with the rotation of the cam 710.

[0052] Figure 9 A first schematic diagram of a movement according to an exemplary embodiment of the present disclosure is shown. Figure 8 A second schematic diagram of a movement according to an exemplary embodiment of the present disclosure is shown. Figure 9 In this movement 800, the actuator 850 covers at least a portion of the upper surface of the movement 800. And... Figure 10 In the middle, the actuator 950 of the movement 900 is lifted by the mechanical drive system described above.

[0053] Figure 11An 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 core 100. 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.

[0054] The movement 100 includes an upper housing 101 and a lower housing 102, which together define a cavity 103 to accommodate various components housed within the movement 100. These components include the aforementioned mechanical drive system 200, and preferably also include a processor 170 and a power supply unit 180. The power supply unit 180 is preferably implemented as a battery to power the processor 170 and the drive mechanism. The processor 170 is preferably implemented as a PCBA circuit board 170. This PCBA circuit board 170 integrates a suitable processor unit such as a microprocessor and a MOS transistor 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 200 is adapted to insert upward into a guide slot in the movement 100, thereby connecting with the actuator 150. In one embodiment of this disclosure, the processor 170 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 150, so that the frequency is adapted to the user's breathing frequency. Furthermore, the pillow core 1000 also includes a control unit 190, which is embedded in a recess on the outer side of the upper housing 1001 and lower housing 1002 of the pillow core 1000, and is adapted to connect to the processor 170, thereby facilitating the user to adjust the rotational frequency of the drive mechanism and, consequently, the reciprocating motion frequency of the actuator 150 from outside the pillow core 1000 by controlling the processor 170, so that the frequency matches the user's breathing frequency. The control unit 190 may be, for example, an external button, including, for example, a power button for the pillow core 1000, a button for adjusting the rotational frequency of the drive mechanism and thus the reciprocating motion frequency of the actuator, and other suitable buttons.

[0055] Figure 11 Another exploded structural diagram of a sleep pillow according to an exemplary embodiment of the present disclosure is shown. ​As shown, the movement 100 has been assembled and is adapted to be housed within the cavity defined by the upper housing 1101 and the lower housing 1102 of the pillow core 1100. The upper housing 1101 and the lower housing 1102 can be adapted to be connected together in any manner suitable in the art. Once the upper housing 1101 and the lower housing 1102 are connected as one unit, the sleep pillow will be shaped to suit user use.

[0056] In one example disclosed herein, during the actual assembly process, the cam is first connected to the drive mechanism and then to the aforementioned mechanical drive system. Subsequently, the assembled components are placed within the movement. Next, the actuator is placed on the upper surface of the movement and connected to the mechanical drive system. The movement is then encapsulated within the sleep pillow.

[0057] This disclosure enhances the undulation of the sleep pillow through a redesigned mechanical drive system. In actual operation, the user can activate the sleep pillow via a control unit. The drive mechanism rotates at a predetermined frequency, for example, 0.5 Hz (similar to the user's breathing rate). Preferably, the user can also adjust the rotation frequency of the drive mechanism via a processor to match the user's current breathing rate. When the drive mechanism provides power, the cam rotates at a predetermined frequency and, in conjunction with a return spring, drives the reciprocating motion of the driven component. Since the actuator is connected to the driven component, it moves synchronously with the driven component, causing the surface of the sleep pillow to rise and fall. Specifically, when the cam is rotating downwards, the actuator moves downwards to contract the sleep pillow surface, simulating the user's breathing phase. When the cam is rotating upwards, the actuator moves upwards to expand the sleep pillow surface, simulating the user's inhalation phase. This creates a continuous and smooth breathing motion, helping the user synchronize their breathing. Furthermore, the amplitude and frequency of the reciprocating motion of the actuator can be adjusted by changing the cam profile and size, the speed of the drive mechanism, the gear settings, etc. This rhythmic movement causes the entire sleep pillow to match the user's breathing rhythm.
