[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings. It should be noted that the embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this invention, and should not be construed as limiting this invention.

[0044] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature; "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] Terms such as “installation,” “connection,” “linking,” and “fixing” should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components, unless otherwise explicitly defined.

[0046] Terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are used solely for the purpose of describing the technical solutions of this invention and do not imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. For example, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium; "above," "on top," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature; "below," "under," and "below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] The present invention provides a posture correction device, including a pad assembly 1 having a reference plane suitable for conforming to a desktop; a correction assembly 2 connected to the pad assembly 1, suitable for forming a limiting block in front of the user's chest to correct the sitting posture; the correction assembly 2 is provided with a first connecting part 210, and the pad assembly 1 is provided with a second connecting part 11 that rotatably engages with the first connecting part 210; it also includes at least one set of adjustment assemblies 3, the adjustment assemblies 3 being connected to the first connecting part 210 and the second connecting part 11.

[0048] The adjustment assembly 3 includes an adjustment column 32 and an adjustment member 31 that cooperates with the adjustment column 32.

[0049] One end of the adjusting column 32 is connected to the first connecting part 210, and the other end passes through the second connecting part 11 and is connected to the adjusting member 31. Alternatively, one end of the adjusting column 32 is connected to the second connecting part 11, and the other end passes through the first connecting part 210 and is connected to the adjusting member 31. Rotating the adjusting member 31 can cause the first connecting part 210 and the second connecting part 11 to abut against each other or release from abutment, thereby fixing or releasing the angle between the corrective component 2 and the pad assembly 1, so that the user can personalize the tilt angle of the corrective component 2 relative to the pad assembly 1 to adapt to different body types or usage preferences.

[0050] After the adjusting component 3 forces the first connecting part 210 and the second connecting part 11 to abut against each other, the friction between the first connecting part 210 and the second connecting part 11 restricts the rotation between the correcting component 2 and the pad assembly 1, thereby fixing the angle between the two to a certain extent.

[0051] Furthermore, a rotation-limiting structure is provided between the first connecting part 210 and the second connecting part 11. After the adjusting component 3 forces the first connecting part 210 and the second connecting part 11 to abut against each other, the rotation-limiting structure engages and limits the angle between the correcting component 2 and the pad assembly 1, further fixing the angle between them. In some embodiments with poorer results, the rotation-limiting structure may not be provided, and the angle between the correcting component 2 and the pad assembly 1 may be fixed solely by friction.

[0052] The following description uses a sitting posture correction device with a rotation limit structure and an adjustment element 31 as a lever as an example.

[0053] Example 1

[0054] like Figure 1-10 As shown, a preferred embodiment of the posture correction device of the present invention is provided, including a pad assembly 1, a correction assembly 2, and an adjustment assembly 3.

[0055] The pad assembly 1 has the aforementioned reference plane and a read / write plane suitable for writing. In this embodiment, the reference plane and the read / write plane are preferably arranged opposite to each other, with the reference plane located at the bottom end of the pad assembly 1, and the correction assembly 2 connected to one side of the read / write plane of the pad assembly 1.

[0056] The correction assembly 2 includes two end rods 21 and a middle rod 22. The two ends of the middle rod 22 are respectively connected to one end of one end rod 21. A first connecting part 210 is provided at the other end of the two end rods 21. The pad assembly 1 is provided with a second connecting part 11 that rotatably engages with a first connecting part 210.

[0057] The two end rods 21 and the middle rod 22 of the correction component 2 are connected in sequence to form an n-shaped structure. When in use, the middle rod 22 physically limits the user's sitting posture or provides a visual warning, thereby achieving the purpose of correcting sitting posture.

[0058] A first connecting part 210 is provided at the end of the middle rod 22, which is far away from the two end rods 21.

[0059] Preferably, a second connecting part 11 is provided on each of the left and right sides of the pad assembly 1, and each of them is rotatably engaged with a first connecting part 210, so that the correction component 2 is rotatably mounted on the pad assembly 1. When the posture correction function is needed, the correction component 2 is rotated to be set at an angle with the pad assembly 1. When not in use, the correction component 2 and the pad assembly 1 can be stacked together to reduce the space occupied by the device and enrich the applicable scenarios of the product.

[0060] Preferably, the two second connecting parts 11 are positioned between the two first connecting parts 210, that is, the first connecting parts 210 are assembled on the outside of the second connecting parts 11, so as to reduce the space occupied by the reading and writing plane.

[0061] Furthermore, the second connecting part 11 is detachably connected to the main body of the pad assembly 1. The pad assembly 1 has an end connector 12, and the second connecting part 11 has a connecting opening into which the end connector 12 is inserted. Preferably, a raised annular retaining edge 113 is provided in the connecting opening, and a retaining groove 121 is provided in the middle of the end connector 12. The end connector 12 is inserted into the retaining groove 121, thereby cooperating with the connecting opening and the end connector 12 to form a double-insertion combination, ensuring the connection stability between the second connecting part 11 and the pad assembly 1. Preferably, the connecting opening and the end connector 12 are further fixed by screws. In other embodiments, the second connecting part 11 is integrally formed with the pad assembly 1.

[0062] Correspondingly, the adjustment component 3 is provided in two sets, which are respectively connected to the combination of the first connecting part 210 and the second connecting part 11 on the left and right sides.

[0063] The adjusting column 32 of the adjusting component 3 is fixedly connected to the first connecting part 210 or the second connecting part 11 at one end away from the adjusting member 31, or the adjusting column 32 has a limiting end at one end away from the adjusting member 31, and the other end passes through the first connecting part 210 and the second connecting part 11 and is connected to the adjusting member 31.

[0064] In this embodiment, specifically, a shaft hole is provided on the first connecting part 210. One end of the adjusting column 32 is fixedly connected to the second connecting part 11, and the other end passes through the shaft hole and connects to the adjusting member 31. This allows the adjusting member 31 to be located outside the pad assembly 1, facilitating operation of the adjusting member 31, reducing interference from the end rod 21, and thus optimizing the user experience. In some embodiments with poorer performance, the adjusting column 32 can be fixedly connected to the first connecting part 210, and a shaft hole can be provided on the second connecting part 11. The adjusting column 32 passes through the shaft hole and connects to the adjusting member 31.

[0065] In other embodiments, a shaft hole is provided on the first connecting part 210 and the second connecting part 11 respectively. A limiting end is provided at one end of the adjusting column 32, and the other end passes through the shaft holes of the first connecting part 210 and the second connecting part 11 in sequence and is connected to the adjusting member 31. Alternatively, the other end passes through the holes of the second connecting part 11 and the first connecting part 210 in sequence and is connected to the adjusting member 31. The limiting end and the adjusting member 31 are located on the two outer sides of the combination of the first connecting part 210 and the second connecting part 11 respectively. Thus, when the adjusting member 31 is rotated, the first connecting part 210 and the second connecting part 11 are forced to abut against each other under the combined action of the adjusting member 31 and the limiting end.

[0066] The adjustment component 3 also includes a rotation limiting structure; the rotation limiting structure is connected between the first connecting part 210 and the second connecting part 11, and when the adjustment component 31 is rotated to a predetermined stroke, the rotation between the first connecting part 210 and the second connecting part 11 can be limited.

[0067] The rotation limiting structure is preferably a meshing toothed groove structure. Therefore, the rotation limiting structure includes a first tooth group 2104 connected to the first connecting part 210; and a second tooth group 114 connected to the second connecting part 11. The first tooth group 2104 includes a plurality of first teeth, which are distributed in a circular shape at one end near the second connecting part 11. The second tooth group 114 includes a plurality of second teeth that mesh with the first teeth. Preferably, both the first teeth and the second teeth are involute teeth.

[0068] In this embodiment, the first tooth set 2104 and the second tooth set 114 are preferably located on the end faces of the first connecting portion 210 and the second connecting portion 11, both having a toothed disc structure. Specifically, the first tooth set 2104 is located at the bottom of the cap of the first connecting portion 210, circumferentially distributed between the connecting post 2101 and the cap skirt 2102, and distributed in a circular pattern. The second tooth set 114 is located on the end face of the second limiting skirt 111 near the first connecting portion 210. When the rotating adjustment member 31 releases the angle fixation, the correction component 2 can be directly rotated to adjust to the expected angle, and then the adjustment member 31 can be rotated in the opposite direction to fix the angle between the correction component 2 and the pad assembly 1. In other embodiments, the first tooth set 2104 may be distributed on the outer wall of the connecting post 2101, and the second tooth set 114 may be distributed on the inner wall of the second limiting skirt 111.

[0069] In this embodiment, the rotational engagement between the first connecting portion 210 and the second connecting portion 11 is achieved through a rotating shaft and a shaft groove. Specifically, an annular second limiting skirt 111 extends from the second connecting portion 11 toward the first connecting portion 210, and a shaft groove is formed on the inner side of the second limiting skirt 111; a cylindrical connecting post 2101 extends from the first connecting portion 210 toward the second connecting portion 11, serving as a rotating shaft, and the connecting post 2101 is fitted into a shaft hole formed on the inner side of the second limiting skirt 111.

[0070] The adjusting column 32 is fixedly connected to the second connecting part 11; an assembly hole 2103 is provided in the connecting column 2101; the adjusting column 32 passes through the assembly hole 2103 and is connected to the adjusting member 31. The adjusting column 32 can be slidably or movably disposed in the assembly hole 2103 along the axial direction. In this embodiment, the adjusting column 32 can preferably also rotate in the assembly hole 2103.

[0071] Preferably, the axis of rotational engagement between the first connecting part 210 and the second connecting part 11 is concentric with the adjusting column 32.

[0072] In some other embodiments, the rotational engagement between the first connecting part 210 and the second connecting part 11 is achieved by a rotating shaft. The rotating shaft and the adjusting column 32 are integrated into one unit. For example, the adjusting column 32 is fixed to the first connecting part 210, and a shaft connection hole is provided on the second connecting part 11. The adjusting column 32 passes through the shaft connection hole and is connected to the adjusting member 31. At this time, the adjusting column 32 is both the shaft that realizes the rotational connection between the first connecting part 210 and the second connecting part 11, and the structure that cooperates with the adjusting member 31 to achieve angle fixation.

[0073] Furthermore, a first annular limiting skirt 112 extends from the second connecting portion 11 toward the first connecting portion 210 and is distributed in an annular shape along the circumference of the adjusting column 32; a hood skirt 2102 that matches the first limiting skirt 112 is provided on the first connecting portion 210. The centers of the first limiting skirt 112 and the hood skirt 2102 are concentrically arranged with the rotation of the first connecting portion 210 and the second connecting portion 11, in order to further increase the stability of the rotation function.

[0074] Furthermore, the hood skirt 2102 is fitted around the outer edge of the first limiting skirt edge 112, and the connecting post 2101 is fitted around the inner edge of the second limiting skirt edge 111, so that the first limiting skirt edge 112 and the second limiting skirt edge 111 are both located between the hood skirt 2102 and the connecting post 2101, thereby increasing the stability of the product structure.

[0075] Furthermore, a stop structure is provided between the first connecting part 210 and the second connecting part 11. After the first connecting part 210 rotates by a predetermined angle, the stop structure can brake the rotation between the first connecting part and the second connecting part 11.

[0076] The stopping structure includes a first stopping block disposed at the first connecting portion 210; and a second stopping block 115 disposed at the second connecting portion 11, located on the rotational travel of the first stopping block. When the correcting component 2 is rotated to a predetermined angle, the second stopping block 115 interferes with the rotation of the first stopping block, thereby keeping the correcting component 2 at the predetermined angle. The predetermined angle is preferably 30 degrees, that is, the angle between the end rod 21 of the correcting component 2 and the pad assembly 1 is 30 degrees.

[0077] In this embodiment, the second stop block 115 is preferably a fan-shaped block and is disposed between the second limiting skirt 111 and the first limiting skirt 112; the first stop block is also disposed in a fan-shaped block and is located outside the first tooth group 2104.

[0078] Furthermore, the adjustment assembly 3 also includes an elastic element 4 connected between the first connecting portion 210 and the second connecting portion 11, adapted to tend to move the first connecting portion 210 away from the second connecting portion 11. When the adjustment assembly 31 releases the contact between the first connecting portion 210 and the second connecting portion 11, the elastic element 4 causes the rotation limiting structure to separate, that is, the first gear set 2104 and the second gear set 114 separate, thereby improving the adjustment efficiency. In this embodiment, the elastic element 4 is preferably a compression spring, with its two ends abutting against the connecting post 2101 of the first connecting portion 210 and the bottom wall of the shaft groove formed by the second limiting edge on the second connecting portion 11, respectively.

[0079] In this embodiment, the adjusting member 31 is a lever member with an eccentric end at one end. The eccentric end is rotatably connected to the adjusting column 32. When the adjusting member 31 is rotated to the first position away from the eccentric end, the eccentric end presses against the first connecting part 210, that is, the distal point 312 corresponding to the eccentric end contacts the first connecting part 210, causing it to move closer to the second connecting part 11. At the same time, the connecting column 2101, driven by the eccentric end, drives the second connecting part 11 to move closer to the first connecting part 210, thereby causing the first connecting part 210 and the second connecting part 11 to abut against each other. Rotate the adjusting member 31 to the second position, the eccentric end eliminates or reduces the pressure on the first connecting part 210, that is, the proximal point 3111 corresponding to the eccentric end contacts the first connecting part 210, the force of the first connecting part 210 and the second connecting part 11 squeezing each other disappears or weakens, thereby releasing the state of mutual abutment between the first connecting part 210 and the second connecting part 11. Then rotate the adjusting and correcting component 2, and after rotating to the expected angle, rotate the adjusting member 31 to the first position again to fix the angle between the correcting component 2 and the pad assembly 1, thus completing the angle adjustment of the correcting component 2.

[0080] Example 2

[0081] As a variation of the above embodiment, the adjusting member 31 is a knob, which is threadedly connected to the adjusting column 32. By rotating the knob, the first connecting part 210 and the second connecting part 11 are made to abut against each other and fixed, or the abutment between the first connecting part 210 and the second connecting part 11 is released.

[0082] In this embodiment, the correction component 2 includes a horizontal bar and a vertical bar, with the first connecting portion 210 provided at the lower end of the vertical bar, and the horizontal bar connected to the upper end of the vertical bar. In some other embodiments where the effect is less satisfactory, the correction component 2 may only have a vertical bar.

[0083] The adjusting column 32 is a cylindrical screw with a limiting end at one end. The first connecting part 210 and the second connecting part 11 are respectively provided with shaft holes. The other end of the adjusting column 32 passes through the two shaft holes and is threaded to the knob. At this time, the adjusting column 32 also serves as a rotating shaft to realize the rotational connection between the first connecting part 210 and the second connecting part 11.

[0084] When it is necessary to adjust the angle of the correction component 2, turn the knob to release the mutual abutment of the first connecting part 210 and the second connecting part 11, then turn the adjustment correction component 2. After turning to the expected angle, turn the knob in the opposite direction to make the first connecting part 210 and the second connecting part 11 abut against each other, thereby fixing the angle between the correction component 2 and the pad assembly 1, and finally completing the angle adjustment of the correction component 2.

[0085] This utility model discloses a posture correction device that is placed on a tabletop using a pad assembly. The correction component is rotatably mounted on the pad assembly via a first and second connecting part. An adjusting component allows the first and second connecting parts to abut or dismount, fixing or releasing the angle between the correction component and the pad assembly. This provides the posture correction device with multiple usage states, improving posture correction efficiency and effectively reducing incorrect sitting postures such as leaning forward or looking down. This makes it easier for users to maintain a comfortable and healthy sitting posture for extended periods, thereby reducing the probability of vision and cervical spine damage and effectively preventing diseases such as myopia, kyphosis, and spinal curvature.

[0086] The above embodiments only illustrate a portion of the implementation methods of the present invention. Any modifications, substitutions, and improvements made by those skilled in the art without departing from the inventive concept of the present invention, without creative effort, are all within the protection scope of the present invention.
