[0002] Children nowadays spend more and more time sitting at desks to study. If the child's sitting posture is incorrect, it is easy to cause hunchback and myopia problems. Therefore, various sitting posture correctors are available on the market to correct children's sitting posture.

[0003] Currently, the sitting posture correctors on the market are generally fixed to the table top through a supporting structure component. The chest support connected to the supporting structure component is used to support the user's chest position to prevent the user from hunching over and ensuring that the user has a relatively standard sitting posture to reduce the pressure on the cervical spine, lumbar spine, and spine. Existing sitting posture correctors can generally only be adjusted in height. However, different users have different body shapes and different chest shapes, so existing sitting posture correctors cannot adapt well to different users, which reduces the comfort of use and the correction effect. Summary of the invention

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] Embodiment 1

[0038] An adaptive sitting posture corrector capable of multi-dimensional activities in this Embodiment 1 includes a chest-top structure member 1, a support structure member 2, and a multi-dimensional activity mechanism. The chest-top structure member 1 is connected to the support structure member 2 through the multi-dimensional activity mechanism. The multi-dimensional activity mechanism restricts the translational freedom of the chest-top structure member 1 in the Y-axis direction, and the chest-top structure member 1 can move in the X-axis and Z-axis directions under the constraint of the multi-dimensional activity mechanism.

[0039] The chest-top structure member is symmetric about the left and right with respect to the support structure member. Specifically, in this embodiment, the support structure member 2 has a horizontally extending support plate located in the upper part, and the chest-top structure member 1 includes two groups of chest support assemblies symmetrically arranged at both ends of the support plate. The two groups of chest support assemblies are adapted to fit the left and right chests of the human body, conforming to ergonomics. Corresponding to the two groups of chest support assemblies, two groups of multi-dimensional activity mechanisms are provided. Under the action of the two groups of multi-dimensional activity mechanisms, the two groups of chest support assemblies respectively perform multi-dimensional activities to adapt to the left and right chests of the user.

[0040] Specifically, the multi-dimensional activity mechanism includes a movable embedding member 3, an elastic member 6, and a first limiting structure member 4 and a second limiting structure member 5 provided on the movable embedding member 3.

[0041] In this embodiment, the movable embedding member 3 is a spherical structure member, which has a spherical part 31. A cuboid connecting block 32 is provided at the front end of the spherical part 31. The chest-top structure member 1 has a chest support plate, and a connecting cavity is provided at the rear side of the chest support plate. The movable embedding member 3 is fixedly connected to the chest-top structure member 1 through the cooperation of the cuboid connecting block 32 and the connecting cavity. A spherical cavity 21a is provided on the support structure member 2, and the spherical part 31 of the movable embedding member 3 is embedded in the spherical cavity 21a of the support structure member 2 and fits with the cavity surface of the spherical cavity 21a to realize the movable connection between the movable embedding member 3 and the support structure member 2. The support structure member 2 is composed of two parts spliced together, that is, the spherical cavity is composed of two parts spliced together. During assembly, first, the spherical part 31 of the movable embedding member 3 is installed in a part of the spherical cavity, and then the other part of the spherical cavity is spliced.

[0042] The first limiting structural member 4 is arranged along the Z-axis passing through the center of the sphere portion 31, and a limiting groove 23 is formed on the wall of the spherical cavity 21a. The first limiting structural member extends into the limiting groove 23. Moreover, the limiting groove 23 is a linear groove extending in the Y-axis direction, that is, the first limiting structural member 4 has a moving space in the Y-axis direction in the limiting groove 23. A conical barrel cavity 22 is further provided in the support structural member 2 behind the spherical cavity 21a; the rear side of the sphere portion 31 is a planar structure, the second limiting structural member 5 is arranged on the rear side of the sphere portion 21a and extends backward into the conical barrel cavity 22. A matching cavity 24 is further provided at the rear part of the support plate of the support structural member 2, and an elastic member 6 is arranged in the matching cavity 24 and extends into the conical barrel cavity 22 to be connected with the second limiting structural member 5. Under the action of the elastic member 6, the movable insertion member 3 and the chest pressing structural member 1 perform elastic activities, so that the movable insertion member 3 and the chest pressing structural member 1 can be reset after the activities. In the present Embodiment 1, the elastic member 6 is a spring.

[0043] The sphere portion 31 of the movable insertion member 3 can rotate in the spherical cavity 21a of the support structural member 2. Specifically, the movable insertion member 3 can rotate in the Z-axis direction around the first limiting structural member 4, thereby driving the chest pressing structural member 1 to rotate in the Z-axis direction; this rotation in the Z-axis direction is restricted by the second limiting structural member 5 and the conical barrel cavity 22 and can be carried out within a certain angle range, so that the chest pressing structural member 1 swings around the Z-axis direction (vertical direction) within a certain angle range. The first limiting structural member 4 has a moving space in the Y-axis direction of the limiting groove 23, so that the sphere portion 31 of the movable insertion member 3 can also rotate around the X-axis, thereby driving the chest pressing structural member 1 to rotate in the X-axis direction; this rotation in the X-axis direction is restricted by the second limiting structural member 5 and the conical barrel cavity 22 and can be carried out within a certain angle range, so that the chest pressing structural member 1 swings around the X-axis direction (horizontal direction) within a certain angle range. Since the first limiting structural member 4 is restricted by the limiting groove 23 in its X-axis direction, the rotation of the sphere portion 31 of the movable insertion member 3 around the Y-axis is restricted, and thus the rotation of the chest pressing structural member 1 around the Y-axis is restricted.

[0044] During use, the sitting posture corrector is assembled on the front side of the table board by means of clamping, sliding insertion, etc. For example, it can be slidably connected with the table board through a height adjustment assembly arranged on the support structural member so as to realize height adjustment during use. During the use process, the chest pressing structural member 1 can perform forward and backward pitching movements around the X-axis direction, so as to adapt to the vertical contour change of the user's chest; the chest pressing structural member 1 can also swing around the Z-axis direction to adapt to the horizontal contour change of the chest. Therefore, the sitting posture corrector of the present invention can adapt to users with different chest shapes, improve the use comfort and ensure the correction effect.

[0045] In addition, since the spherical part 31 of the movable insert 3 is inserted into the spherical cavity 21a of the support structure 2, the translational movement of the movable insert 3 in the Y-axis (front-back direction) is restricted, so that the chest support structure 1 will not expand and contract in the front-back direction, providing more effective support and more effectively maintaining the user's chest-up posture.

[0046] In this embodiment, the contour surfaces of the chest support components are all arc surfaces, which can better fit the chest curve, increase the contact area between the chest support components and the chest, make the force more uniform, avoid discomfort caused by excessive local pressure, and improve comfort.

[0047] Embodiment 2

[0048] An adaptive sitting posture corrector capable of multi-dimensional movement in this Embodiment 2 includes a chest support structure 1, a support structure 2, and a multi-dimensional movement mechanism. Among them, the support structure 2 has a horizontally extending support plate located at the upper part, and the chest support structure 1 includes two groups of chest support components symmetrically arranged at both ends of the support plate. The two groups of chest support components are adapted to fit the left and right chests of the human body. The chest support structure 1 is connected to the support structure 2 through the multi-dimensional movement mechanism. Corresponding to the two groups of chest support components, two groups of multi-dimensional movement mechanisms are provided. The multi-dimensional movement mechanism restricts the translational freedom of the chest support structure 1 in the Y-axis direction, and the chest support structure 1 can move in the X-axis and Z-axis directions under the constraint of the multi-dimensional movement mechanism.

[0049] In this embodiment, the support structure 2 has a horizontally extending support plate located at the upper part, and the chest support structure 1 includes two groups of chest support components symmetrically arranged at both ends of the support plate. The two groups of chest support components are adapted to fit the left and right chests of the human body, conforming to ergonomics. Corresponding to the two groups of chest support components, two groups of multi-dimensional movement mechanisms are provided. Under the action of the two groups of multi-dimensional movement mechanisms, the two groups of chest support components respectively perform multi-dimensional movements to adapt to the left and right chests of the user.

[0050] Specifically, the multi-dimensional movement mechanism includes a movable insert 3, an elastic member 6, a first limiting structure member 4, and a second limiting structure member 5.

[0051] In this embodiment, the movable insert 3 is a cuboid structural member. The support plate of the support structural member 2 has an assembly cavity 21b. The rear part of the movable insert 3 is inserted into the assembly cavity 21b of the support structural member 2 and is rotatably connected to the support structural member 2 through a first limiting structural member 4 extending in the Z-axis direction. The chest support structural member 1 has a chest support plate, and a connection cavity 11 is provided at the rear side of the chest support plate. The front part of the movable insert 3 is inserted into this connection cavity 11 and is rotatably connected to the chest support structural member 1 through a second limiting structural member 5 extending in the X-axis direction. Reset grooves are respectively provided at the front and rear parts of the movable insert 3, and elastic members 6 located in this reset groove are provided between the movable insert 3 and the chest support structural member 1 as well as between the rear part of the movable insert 3 and the support structural member 2. Under the action of the elastic member 6, the movable insert 3 and the chest support structural member 1 perform elastic activities, enabling the movable insert 3 and the chest support structural member 1 to be reset after the activity. In this embodiment 2, the elastic member 6 is a spring.

[0052] The movable insert 3 can rotate in the Z-axis direction around the first limiting structural member 4, thereby driving the chest support structural member 1 to rotate in the Z-axis direction; this rotation in the Z-axis direction is restricted by the assembly cavity 21b of the support structural member 2 and can be carried out within a certain angle range, so that the chest support structural member 1 swings around the Z-axis direction (vertical direction) within a certain angle range. The movable insert 3 can also rotate around the second limiting structural member 5, thereby driving the chest support structural member 1 to rotate in the X-axis direction; this rotation in the X-axis direction is restricted by the connection cavity 11 of the chest support structural member 1 and can be carried out within a certain angle range, so that the chest support structural member 1 swings around the X-axis direction (horizontal direction) within a certain angle range.

[0053] During use, as Figure 9 shown, the sitting posture corrector is assembled on the front side of the tabletop by means of clamping, sliding insertion, etc. For example, it can be slidably connected to the tabletop through a height adjustment assembly provided on the support structural member to achieve height adjustment during use. During the use process, the chest support structural member 1 can perform forward and backward pitching movements around the X-axis direction, so as to adapt to the vertical contour changes of the user's chest; the chest support structural member 1 can also rotate around the Z-axis direction to adapt to the horizontal contour changes of the chest. Therefore, the sitting posture corrector of the present invention can adapt to users with different chest shapes, improve the use comfort, and ensure the correction effect.

[0054] In addition, adopting the structure of this embodiment 2, the chest support structural member 1 will not expand and contract in the front and rear directions, so more effective support can be provided and the user's chest-out posture can be maintained more effectively.

[0055] The above are only embodiments of the present invention, and do not thereby limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
