PILLOW LIFTING STRUCTURE

Abstract

A pillow lifting structure includes a bottom plate. The bottom plate is provided with a power unit. The power unit is connected to a linking unit. The top of the linking unit is covered with a cover. The power unit actuates to deform the linking unit for adjusting the height of the cover in time so as to adjust the height of the top surface of the pillow. The X-shaped linking unit of the pillow lifting structure is lifted by a driven arcuate gear with a push arm. This action is a direct push, and there is no power consumption. Only a small motor is required for actuation. Space and energy consumption are optimized by the direct push.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Referring to FIG. 1 through FIG. 6, the pillow lifting structure of the present invention comprises a bottom plate 1. The bottom plate 1 is provided with a power unit 2. The power unit 2 is connected to a linking unit 3. The top of the linking unit 3 is covered with a cover 4. The power unit 2 is disposed on the bottom plate 1. The power unit 2 includes a motor 21. An output end of the motor 21 is connected to a speed reducer 22. An output end of the speed reducer 22 is connected to a driving gear 23. The driving gear 23 is meshed with a driven arcuate gear 24. A rotating shaft portion 25 is disposed at the arc center of the driven arcuate gear 24. The rotating shaft portion 25 is axially mounted to a fixing seat 20 beside the speed reducer 22. The driven arcuate gear 24 is connected with a push arm 26. The distal end of the push arm 26 is provided with a pulley 27. The linking unit 3 includes a first body 31 and a second body 32. The first body 31 is in the form of a Chinese character . The second body 32 is in the form of a Chinese character . The first body 31 and the second body 32 are engaged with each other to form an X shape. Two ends of a lower side of the first body 31 are provided with first pulleys 312. One side of the first body 31 is provided with a side plate 313. A side pulley 314 is connected to the distal end of the side plate 313. The bottom surface of the first body 31 is provided with a guide rail 315. The guide rail 315 is provided with a wear plate 316. The wear plate 316 is located on the top edge of the pulley 27 of the push arm 26 of the power unit 2. Two ends of a higher side of the second body 32 are provided with second pulleys 322. A central hinge 33 is provided at the junction of the first body 31 and the second body 32. The bottom plate 1 is a flat plate. The bottom plate 1 is provided with at least one second hinge 11 connected with the lower side of the second body 32. The at least one second hinge 11 provides axial movement of the second body 32 relative to the bottom plate 1. The bottom plate 1 is provided with a potentiometer 14. The side pulley 314 can be moved on the potentiometer 14. The bottom plate 1 is provided with a pair of rails 13. The pair of rails 13 is configured to limit the first pulleys 312 to roll thereon. The cover 4 is located on top of the linking unit 3. A part of the bottom surface of the cover 4 is in contact with and supported by the second pulleys 322. A higher side of the first body 31 is provided with at least one first hinge 317. The first hinge 317 is connected with the cover 4.

[0025] FIG. 6 is a schematic view of the pillow of the present invention at the lowest position. When the pillow is to be lifted, as shown in FIG. 7 and FIG. 8, the motor 21 of the power unit 2 is actuated, and the driving gear 23 is rotated after decelerating by the speed reducer 22 and increasing the thrust. The driven arcuate gear 24 in meshing relationship with the driving gear 23 will be linked to change the position and angle, and then the push arm 26 is linked to move the pulley 27. At the same time, the pulley 27 will lift relative to the guide rail 315 of the first body 31. Since the first body 31 and the second body 32 are in a linked relationship through the central hinge 33, when one end of the first body 31 is lifted, under the control of the second hinge 11 connected to the bottom plate 1, the first body 31 and the second body 32 as a whole will rise synchronously, and the side pulley 314 will move on the potentiometer 14 to detect the relative moving position (as shown in FIG. 9). Finally, the purpose of lifting is completed. On the contrary, when the pillow is to be lowered, the motor 21 is rotated reversely, and the height of the pillow is lowered in accordance with the above principle.

[0026] In the present invention, the extent of lifting and lowering can be slightly adjusted as desired according to the actuation of the motor 21, and the potentiometer 14 is used to detect the relative state and position of the movement. During the displacement, the system can control the height of lifting and lowering through the electrical information of the potentiometer 14. The height required for different sleeping postures of the user can be preset, and the automatic adjustment can be performed to achieve a height change.

[0027] As shown in FIG. 10, in the implementation of the present invention, a soft cushion 5 is provided on top of the cover 4.

[0028] In summary, the pillow lifting structure of the present invention can achieve the purpose of individually setting and automatically adjusting the height of the pillow with a miniaturized mechanism, which can improve the sleep quality of the user effectively.

[0029] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
