Description

Technical Field

[0001] The utility model relates to the technical field of pillows, and particularly relates to a pneumatic-powered lifting pillow. Background Art

[0002] A lifting pillow is a pillow with an innovative design. Its main feature is that it can automatically adjust its height according to the user's sleeping position, thereby providing a better sleep experience and cervical support. Lifting pillows usually achieve automatic height adjustment through an internal mechanical structure or an airbag system. For example, some lifting pillows are internally provided with spring brackets that can automatically rise and fall to a suitable height according to the pressure of turning over; while others adopt an air-filled bag design and adjust the height of the pillow by inflating and deflating. In addition, some lifting pillows incorporate sensing devices that can sense the user's sleeping position and make corresponding adjustments.

[0003] For existing pneumatic lifting pillows, a relatively large airbag is arranged inside the pillow to cover the whole pillow. Although the height adjustment of the pillow can be achieved by inflating and deflating the airbag, the airbag has a large capacity, and a relatively large amount of gas needs to be processed for inflating and deflating the airbag, which increases the time and energy consumption required for inflating and deflating, and the lifting adjustment efficiency is relatively low, which is not conducive to quickly lifting and adjusting the height of the pillow. Summary of the Invention

[0005] The purpose of the utility model is achieved by the following technical solutions: A pneumatic-powered lifting pillow includes a base, a pillow pressing plate, an inflatable and deflatable airbag, a central shaft, an airbag top plate, and two scissor-type lifting frames respectively arranged at both ends of the base. The two scissor-type lifting frames are respectively hinged at both ends of the central shaft. One end of the bottom of the scissor-type lifting frame is hinged to the base, and the other end of the bottom of the scissor-type lifting frame is slidably matched with the base. One end of the top of the scissor-type lifting frame is hinged to the pillow pressing plate, and the other end of the top of the scissor-type lifting frame is slidably matched with the pillow pressing plate. The airbag top plate is sleeved on the central shaft, and the inflatable and deflatable airbag is clamped between the base and the airbag top plate.

[0014] The beneficial effects of the present utility model are as follows: The airbag-powered lifting pillow of the present utility model adopts a base, a pillow pressing plate, an inflatable / deflatable airbag, a central axis, an airbag top plate, and two scissor lifts respectively arranged at both ends of the base. The two scissor lifts are respectively hinged at both ends of the central axis, and the airbag top plate is sleeved on the central axis.

[0015] In addition, an inflatable and deflatable airbag is clamped between the base and the airbag top plate. During the inflation and deflation process of the inflatable and deflatable airbag, the airbag top plate is lifted and lowered, the airbag top plate drives the central shaft to lift and lower, and then drives the scissor lift to open and close, so as to adjust the height of the pillow pressing plate. Due to the characteristics of the scissor lift, every time the airbag top plate moves up and down a distance in the height direction, the distance that the scissor lift drives the pillow pressing plate to move up and down in the height direction is greater than the distance that the airbag top plate moves up and down in the height direction. That is, the time required for lifting and lowering adjustment of the pillow pressing plate is shortened, and the lifting and lowering adjustment efficiency is higher, which is beneficial to quickly lifting and adjusting the height of the pillow.

Detailed Embodiment

[0021] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0022] As Figures 1-4 shown, an airbag-powered lifting pillow includes a base 1, a pillow pressing plate 2, an inflatable and deflatable airbag 3, a central shaft 4, an airbag top plate 5, and two scissor lifts 6 respectively arranged at both ends of the base 1. The two scissor lifts 6 are respectively hinged at both ends of the central shaft 4. The bottom end of one side of the scissor lift 6 is hinged to the base 1, the bottom end of the other side of the scissor lift 6 is slidably matched with the base 1, the top end of one side of the scissor lift 6 is hinged to the pillow pressing plate 2, the top end of the other side of the scissor lift 6 is slidably matched with the pillow pressing plate 2. The airbag top plate 5 is sleeved on the central shaft 4, and the inflatable and deflatable airbag 3 is clamped between the base 1 and the airbag top plate 5.

[0023] This airbag-powered lifting pillow adopts a base 1, a pillow pressing plate 2, an inflatable / deflatable airbag 3, a central shaft 4, an airbag top plate 5, and two scissor-type lifting frames 6 respectively arranged at both ends of the base 1. The two scissor-type lifting frames 6 are respectively hinged at both ends of the central shaft 4. The airbag top plate 5 is sleeved on the central shaft 4. By means of the scissor-type lifting frame 6, the height of the pillow pressing plate 2 is adjusted. The stability is higher. Compared with the traditional use mode where a larger airbag covers the whole pillow, in this scheme, a smaller-capacity inflatable / deflatable airbag 3 can be selected to meet the requirements. The amount of gas to be processed for inflation and deflation is smaller, which is more conducive to shortening the time required for inflation and deflation;

[0024] In addition, the inflatable / deflatable airbag 3 is clamped between the base 1 and the airbag top plate 5. During the inflation and deflation process of the inflatable / deflatable airbag 3, the airbag top plate 5 is lifted and lowered to adjust, the airbag top plate 5 drives the central shaft 4 to lift and lower, and then drives the scissor-type lifting frame 6 to open and close to adjust the height of the pillow pressing plate 2. Due to the characteristics of the scissor-type lifting frame 6, for every distance the airbag top plate 5 moves up and down in the height direction, the distance that the scissor-type lifting frame 6 drives the pillow pressing plate 2 to move up and down in the height direction is greater than the distance that the airbag top plate 5 moves up and down in the height direction. That is, the time required for the pillow pressing plate 2 to adjust the height by lifting and lowering is shortened, and the lifting and lowering adjustment efficiency is higher, which is conducive to quickly lifting and adjusting the height of the pillow.

[0025] Furthermore, a first hinge support 7 is arranged on one side of the base 1, and the bottom end of the scissor-type lifting frame 6 is hinged to the base 1 through the first hinge support 7; a second hinge support 8 is arranged on one side of the pillow pressing plate 2, and the top end of the scissor-type lifting frame 6 is hinged to the pillow pressing plate 2 through the second hinge support 8.

[0026] Furthermore, a first limit sliding groove 9 is arranged on the other side of the base 1, and the bottom end of the other side of the scissor-type lifting frame 6 is slidably matched with the base 1 through the first limit sliding groove 9; a second limit sliding groove 10 is arranged on the other side of the pillow pressing plate 2, and the top end of the other side of the scissor-type lifting frame 6 is slidably matched with the pillow pressing plate 2 through the second limit sliding groove 10.

[0027] Furthermore, the scissor-type lifting frame 6 includes a first scissor arm 61 and a second scissor arm 62. One end of the first scissor arm 61 is hinged to the base 1, the other end of the first scissor arm 61 is slidably matched with the pillow pressing plate 2, one end of the second scissor arm 62 is hinged to the pillow pressing plate 2, the other end of the second scissor arm 62 is slidably matched with the base 1, and the first scissor arm 61 and the second scissor arm 62 are cross-hinged at the end of the central shaft 4.

[0028] With the above technical solution, the first scissor arm 61 and the second scissor arm 62 are cross-hinged, and the central axis 4 serves as the hinge axis of the first scissor arm 61 and the second scissor arm 62. During the lifting and lowering process of the central axis 4, with the cooperation of the base 1 and the pillow plate 2, the first scissor arm 61 and the second scissor arm 62 are opened and closed to drive the pillow plate 2 to lift and lower. Furthermore, the end of the central axis 4 passes through the second scissor arm 62 and the first scissor arm 61 and is locked with the locking member 11 to prevent the central axis 4 from falling off. The locking member 11 includes but is not limited to a nut, that is, the end of the central axis 4 has an external thread, and the end of the central axis 4 is threaded with the nut.

[0029] Furthermore, the air supply end of the inflatable and deflable airbag 3 is connected to an air supply pipe 12 for communicating with an external inflation and deflable air system. It should be noted that the external inflation and deflable air system belongs to the prior art, such as an inflation and deflable air pump or a latex ball with a valve, etc., and an inflation and deflable air pump is preferred. Compared with the traditional built-in motor driven lifting pillow, the airbag powered lifting pillow uses the inflatable and deflable airbag 3 to adjust the airbag top plate 5 during the inflation and deflating process, avoiding the generation of loud noise inside the pillow when the built-in motor is running, saving space for the built-in motor of the pillow, and being conducive to the pillow being able to drop to the lowest position after the inflatable and deflable airbag 3 is completely deflated and avoiding the problem of the pillow being blocked from descending due to the built-in motor.

[0030] Furthermore, the bottom surface of the airbag top plate 5 has a plurality of ridges 13 protruding therefrom for abutting against the inflatable and deflable airbag 3 so that the airbag top plate 5 and the inflatable and deflable airbag 3 can fit more closely. Preferably, the number of the ridges 13 is 4, and the four ridges 13 are respectively located at the four corners of the bottom surface of the airbag top plate 5.

[0031] Furthermore, the airbag powered lifting pillow also includes two cross-hinged frames 15 respectively arranged on both sides of the base 1, one bottom end of the cross-hinged frame 15 is hinged to the base 1, and the other bottom end of the cross-hinged frame 15 is slidably matched with the base 1, one top end of the cross-hinged frame 15 is hinged to the pillow pressure plate 2, and the other top end of the cross-hinged frame 15 is slidably matched with the pillow pressure plate 2, which is more conducive to improving the overall supporting stability of the airbag powered lifting pillow.

[0032] Furthermore, a third hinge support 16 is provided at one end of the base 1, and the bottom end of the cross-hinged frame 15 is hinged to the base 1 through the third hinge support 16; a fourth hinge support 17 is provided at one end of the pillow pressure plate 2, and the top end of the cross-hinged frame 15 is hinged to the pillow pressure plate 2 through the fourth hinge support 17.

[0033] Further, the other end of the base 1 is provided with a third limiting sliding groove 18, and the other end of the bottom of the cross hinge frame 15 is slidably matched with the base 1 through the third limiting sliding groove 18; the other end of the pillow pressing plate 2 is provided with a fourth limiting sliding groove 14, and the other end of the top of the cross hinge frame 15 is slidably matched with the pillow pressing plate 2 through the fourth limiting sliding groove 14, so as to realize the opening and closing of the cross hinge frame 15.

[0034] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
