DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The utility model relates to a turning mechanism, which comprises a base 100 and a pillow assembly.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base 100 can be set to an L shape or other shapes. During normal use, the base 100 is in an upright state. The pillow assembly is installed on the base 100. The pillow assembly includes a pillow portion 200 and a connecting seat 300. The connecting seat 300 can be rotatably mounted on the base 100 via a rotating shaft, and the connecting seat 300 is preferably located at the top of the base 100. The pillow portion 200 is slidably connected to the connecting seat 300, and the pillow portion 200 can translate on the connecting seat 300 and be fixed at the current relative sliding position. The entire pillow assembly can be flipped up and down relative to the base 100 via the connecting seat 300. As shown Figure 6As shown, the pillow assembly is flipped downward and fixed in the first position. At this time, when the pillow 200 slides relative to the connecting seat 300, the sliding direction of the pillow 200 is also vertical relative to the base 100. The vertical direction is preferably vertical lifting, and it can also be vertical lifting with a certain slope. When the pillow 200 is lifted to a certain height position, the pillow 200 can be fixed on the connecting seat 300, so that the pillow 200 is fixed in the current position for use. Figure 7 As shown, the pillow assembly flips upward and is positioned in the second position. At this time, the pillow portion 200 slides relative to the connecting seat 300, and the sliding direction of the pillow portion 200 is also a lateral movement relative to the base 100. The lateral movement is preferably a horizontal lateral movement, which is perpendicular to the vertical movement direction of the pillow portion 200 when in the first position. The lateral movement can also be a lateral movement with a certain slope. After the pillow portion 200 moves laterally relative to the base 100, it can be fixed in the current lateral position by the connecting seat 300. The utility model also relates to a sitting posture corrector, which uses a flipping mechanism.

[0034] When using, Figure 6 As shown, the pillow assembly is in the first position, and the sitting posture corrector has a sitting posture adjustment function. The pillow 200 can be raised and lowered relative to the base 100, thereby changing the height of the pillow 200. Figure 7 As shown, when the pillow assembly is flipped to the second position, the sitting posture corrector has a prone sleeping function. The pillow portion 200 can be translated relative to the direction of approaching or moving away from the user to meet the user's different prone sleeping positions. The pillow assembly can quickly switch between the first position and the second position, and adjust the vertical position or the horizontal position to meet the different usage requirements of the user, which is convenient to use.

[0035] Among them, in some embodiments of the present utility model, such as Figure 2 , Figure 3 and Figure 4As shown, the pillow 200 is provided with a slide rail 210 and a plurality of recesses 220. One, two or more slide rails 210 may be provided on the pillow 200. The slide rail 210 extends along the sliding direction of the pillow 200 relative to the connecting seat 300. In this embodiment, two slide rails 210 are symmetrically provided on both sides of the pillow 200. A plurality of recesses 220 are located on the surface of the pillow 200 between the two slide rails 210. The recesses 220 are arranged in sequence along the length direction of the slide rail 210, that is, they are distributed in sequence along the sliding direction of the pillow 200 relative to the connecting seat 300. The recesses 220 are formed by being recessed inward from the surface of the pillow 200. The connecting seat 300 is provided with a first slide groove 310 and a convex portion 320. The direction in which the first slide groove 310 extends is consistent with the direction of the slide rail 210, and the number of the first slide groove 310 provided is consistent with the number of the slide rails 210. One or more convex portions 320 may be provided. The convex part 320 protrudes outward from the surface of the connecting seat 300. The shape of the convex part 320 and the concave part 220 can be matched, and the convex part 320 is convex in an arc surface, and the concave part 220 is concave in an arc surface. The slide rail 210 and the first slide groove 310 are matched and slidably connected one by one. When the pillow 200 slides relative to the connecting seat 300, the movement of the pillow 200 is guided by the cooperation of the slide rail 210 and the first slide groove 310. As the pillow 200 and the connecting seat 300 move relative to each other, the convex part 320 can slide in and out of each concave part 220 in sequence. When the convex part 320 slides into the concave part 220, it is equivalent to the convex part 320 being clamped in the current concave part 220, thereby fixing the pillow 200 at the current position of the connecting seat 300. The user only needs to apply a force to the pillow 200 to make the convex part 320 slide out of the concave part 220 to adjust the moving position of the pillow 200 relative to the connecting seat 300.

[0036] Further, such as Figure 5 As shown, a second slide groove 110 is provided on the base 100. The second slide groove 110 extends vertically along the height direction of the base 100. The upper end of the second slide groove 110 is open. Two second slide grooves 110 can be provided, respectively located on both sides of the base 100. When the pillow assembly is flipped to the first position, the slide rail 210 is initially located outside the second slide groove 110. Then the pillow 200 is moved downward, and part of the slide rail 210 can slide into the slide groove from the upper end of the second slide groove 110. At this time, part of the slide rail 210 remains in sliding contact with the first slide groove 310. By utilizing the cooperation of the second slide groove 110 and the slide rail 210, the pillow 200 is restricted from flipping upward toward the second position, so that the pillow 200 remains in the current orientation. At the same time, the pillow 200 can be restricted from swinging relative to the base 100. When the pillow portion 200 moves upward to a certain height, the slide rail 210 slides out of the upper end of the second slide groove 110, releasing the flipping restriction on the pillow portion 200, and the pillow assembly can flip from the first position to the second position.

[0037] In some specific embodiments of the present invention, Figure 3 and Figure 7 As shown, a limiting portion 330 is provided on the connection base 300. The limiting portion 330 can be formed by protruding in a boss shape on the connection base 300. When the pillow assembly is flipped to the second position, the limiting portion 330 can abut against the base 100 to limit the flipping stroke of the pillow assembly from the first position to the second position.

[0038] Further, such as Figure 3 and Figure 5 As shown, the connection base 300 is provided with a groove 340, and the base 100 is provided with a convex strip 120. When the connection base 300 is flipped to the second position, the convex strip 120 is snapped into the groove 340. A ticking sound is generated when the convex strip 120 is snapped into the groove 340, and the snapping feeling is transmitted to the user's hand, thereby prompting the user that the pillow assembly is flipped to the second position. The convex strip 120 and the groove 340 can be arranged parallel to the rotation axis of the connection base 300.

[0039] In some embodiments of the present invention, Figure 7 As shown, the pillow portion 200 includes a pillow seat 230 and a pillow body 240. The pillow seat 230 is slidably connected to the connecting seat 300. One, two or more pillow bodies 240 can be arranged on the pillow seat 230. The pillow body 240 can be a cloth pillow, a silicone pillow, etc. A buffer mechanism 400 is arranged between the pillow body 240 and the pillow seat 230. The user can lean on the pillow body 240, and the buffer mechanism 400 increases the comfort when leaning on the pillow body 240. Among them, the buffer device includes a spring. The spring provides a buffering effect to the pillow body 240.
