[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] Currently, the most common desktop posture correctors on the market are divided into two categories: fixed and adjustable. Adjustable posture correctors can be adjusted to some extent compared to fixed posture correctors, but their adjustment range is still limited, only allowing for 180° rotation, that is, rotating the posture corrector from vertically upward to vertically downward. Although this adjustment method can achieve some degree of concealment of the posture corrector, it cannot achieve full concealment or storage.

[0042] Furthermore, when the posture correction platform is rotated to a vertically downward position, it will occupy the vertical space under the table.

[0043] Based on this, the present invention provides a hidden vision protection posture correction table, which adopts a two-stage flipping method to enable the limiting component to rotate at least 270°, thereby completely hiding it in the installation reference, solving the problem that the existing limiting component can only be partially hidden.

[0044] The following is combined with Figures 1 to 7 This invention details the first aspect of the concealed vision protection posture correction table and the second aspect of the vision protection posture correction desk.

[0045] Example 1

[0046] According to an embodiment of the present invention, in a first aspect, a concealed vision protection posture correction table is provided, combined with... Figures 1 to 3 As shown, the device includes a base component 2 and a limiting component 1. The base component 2 is rotatably mounted on the mounting reference 3, and has a first position and a second position. The limiting component 1 is rotatably mounted on the base component 2, and is arranged side by side with the base component 2. The limiting component 1 has a third position and a fourth position. The limiting component 1 includes a limiting part for correcting sitting posture.

[0047] When the base component 2 is in the first position and the limiting component 1 is in the third position, the limiting part of the limiting component 1 is located below the reference surface formed by the mounting reference 3. At this time, the limiting component 1 is in a hidden state, so that the entire posture platform is completely hidden below the mounting reference 3 when not in use, without occupying extra space and keeping the upper surface of the reference surface clean.

[0048] When the base component 2 is in the second position and the limiting component 1 is in the fourth position, the limiting part of the limiting component 1 is located above the reference plane. This is the usable state of the limiting component 1, providing effective support and correction. More specifically, the limiting component 1 is arranged parallel to the side of the mounting reference 3, and the limiting component 1 protrudes upwards from the top surface of the mounting reference 3. When the user sits on the side of the mounting reference 3, the limiting component 1 abuts against the user's chest, thereby correcting posture.

[0049] The aforementioned concealed posture correction platform for vision protection employs a two-stage flipping mechanism, allowing the limiting component 1 to rotate at least 270°, thus completely concealing it beneath the mounting base 3. This solves the problem of existing limiting components 1 only being partially concealed. Users can easily switch the limiting component 1 from the concealed state to the usable state as needed; the operation is simple and requires no disassembly, improving convenience and flexibility. When the limiting component 1 is in the usable state, its stable support effectively prevents safety hazards caused by improper posture. Simultaneously, when the limiting component 1 is in the concealed state, because it is completely retracted beneath the mounting base 3, it does not obstruct the user or surrounding objects, further enhancing safety.

[0050] The aforementioned concealed vision protection posture correction desk is suitable for office or home environments with high space requirements, such as small apartments and shared office spaces, and can provide effective posture correction functions within limited space.

[0051] In some embodiments, the concealed vision protection posture correction table also includes a mounting member 4, which is connected to the mounting reference 3, and the base member 2 is rotatably connected to the mounting member 4 so that the base member 2 is rotatably set relative to the mounting reference 3.

[0052] The mounting base 3 has a first notch 32, and the base component 2 is rotatably connected to the mounting component 4. The mounting component 4 is embedded into the first notch 32. The base component 2 is embedded into the first notch 32 of the mounting base 3, and can be flexibly flipped through the rotatable connection, making the entire device more compact, reducing external protrusions, and avoiding unnecessary space occupation. When not in use, the base component 2 can be completely stored inside the mounting base 3, maintaining a neat appearance.

[0053] In some embodiments, the mounting member 4 is provided with a second notch 41, and the mounting member 4 is embedded into the lower part of the side wall of the second notch 41. The first notch 32 and the second notch 41 are arranged side by side or partially overlapped. The base member 2 is at least embedded in the second notch and rotatably connected to the mounting member 4. When the base member 2 is in the second position and the limiting member 1 is in the fourth position, the base member 2 is flipped into the second notch and accommodated by the second notch 41. That is, when the limiting member 1 is in the hidden state, the second notch 41 on the mounting member 4 can effectively accommodate the base member 2, and the upper surface and sides of the mounting reference 3 are flat, with no notches or exposed parts, which does not affect the normal use of the mounting reference 3.

[0054] In some embodiments, when the base component 2 is in the first position, the top surface of the base component 2 is flush with the bottom surface of the mounting reference 3, so that the limiting component 1 will not affect the mounting reference 3 when it is stored, thus ensuring the flatness of the mounting reference 3.

[0055] In some embodiments, the mounting component 4 is a flexible component. More specifically, the mounting component 4 may be a flexible plastic component to accommodate the first notch of the mounting reference 3. Even if slight positional deviations or dimensional errors occur during the installation process, they can be compensated by the deformation and adaptability of the flexible material, ensuring that the base component 2 can be smoothly embedded and rotated.

[0056] In some embodiments, the mounting member 4 includes a flexible joint disposed between the mounting member 4 and the first notch 32 to improve the fit of the mounting member 4 and enhance its stability. The flexible structure has a certain degree of elasticity and cushioning performance, which can play a shock absorption role when the mounting member 4 is subjected to external impact, helping to reduce the impact of external vibration or collision on the mounting member 4 and its surrounding components.

[0057] In some embodiments, the mounting component 4 is detachably disposed within the first notch 32 of the mounting base 3. Because the mounting component 4 is detachable, users or maintenance personnel can easily remove it from the first notch 32 for replacement or repair, greatly simplifying the maintenance process and reducing the need to replace the entire posture aligner due to component damage or wear. The detachable design allows users to select different types of mounting components 4 according to different needs, such as mounting components of different shapes, sizes, or functions, to adapt to different usage scenarios or personal preferences.

[0058] In some embodiments, the mounting component 4 is slidably disposed within the first notch 32 of the mounting base 3. This sliding arrangement allows the mounting component 4 to be adjusted within the first notch 32 to accommodate different usage requirements or installation positions. For example, the position of the mounting component 4 can be fine-tuned as needed to ensure optimal installation. This enhances the product's flexibility, enabling it to better adapt to different application scenarios and individual preferences.

[0059] When it is necessary to disassemble or assemble the mounting part 4, the sliding mechanism allows the mounting part 4 to be easily slid in or out from one end of the first notch without complicated tools or operating procedures.

[0060] In some embodiments, the base component 2 is rotatably mounted on the mounting reference 3 via a first rotating component, and the limiting component 1 is mounted on the base component 2 via a second rotating component. The axis of the first rotating component is parallel to the axis of the second rotating component, so that the two rotational actions do not interfere with each other and maintain their independence and stability.

[0061] In some embodiments, when the limiting member 1 is located directly below the mounting reference 3 and arranged parallel to the reference plane of the mounting reference 3, the limiting member 1 is in a hidden state. When the limiting member 1 protrudes upward from the top surface of the mounting reference 3, the limiting member 1 is in a used state, and the base member 2 and the limiting member 1 are arranged vertically or horizontally side by side.

[0062] When the use state of the limiting component 1 is changed to the storage and hiding state, the limiting component 1 is flipped first, and then the base component 2 is flipped, or the base component 2 is flipped first, and then the limiting component 1 is flipped.

[0063] In some embodiments, a mounting portion 21 protrudes from the side wall of the base member 2, and a limiting member 1 is rotatably mounted on the mounting portion 21.

[0064] In some embodiments, an angle positioning structure is provided at the axis position of rotation of the limiting member 1 relative to the base member 2 to limit the rotational position of the limiting member 1 relative to the base member 2. The angle positioning structure is a damping control structure, which includes a damper disposed at the axis position of rotation of the limiting member 1 relative to the base member 2.

[0065] As an alternative embodiment, the angle positioning structure is a slot-type rotation control structure, which includes a slot and an elastic buckle adapted to the slot. The slot is disposed on the limiting member 1, and the elastic buckle is disposed on the base member 2; or, the slot is disposed on the base member 2, and the elastic buckle is disposed on the limiting member 1.

[0066] In some embodiments, when the limiting member 1 is in the third position, the limiting member 1 is arranged parallel to the reference plane of the mounting reference or the angle between the limiting member and the reference plane of the mounting reference is less than 30 degrees.

[0067] When the aforementioned concealed vision protection posture correction table is stored, the limiting member 1 is arranged parallel to the bottom surface of the mounting reference 3. The first usage process of the aforementioned concealed vision protection posture correction table is as follows:

[0068] When needed, rotate the limiting member 1 (which is in a hidden state) located directly below the mounting reference 3 by 180°. At this time, the limiting member 1 and the base member 2 are in a horizontal state, meaning that the limiting member 1 is in a temporarily hidden position. Then rotate the base member 2 so that the base member 2 and the limiting member 1 rotate 90° in the vertical plane, making the side of the limiting member 1 parallel to the side of the mounting reference 3. The limiting member 1 protrudes upward from the top surface of the mounting reference 3, thus converting the limiting member 1 into a usable state, allowing the user to correct their sitting posture.

[0069] When storage is required, the base component 2 connected to the limit component 1 in use is rotated 90° in the opposite direction in the vertical plane. At this time, the limit component 1 is arranged horizontally, that is, the limit component 1 is in a temporary hidden position. Then, the limit component 1 is rotated 180° in the opposite direction (it can be less or greater than 180°) to store the limit component 1 at the bottom of the mounting base 3. At this time, the limit component 1 is converted to a hidden state, thus realizing the hiding of the limit component 1.

[0070] When the aforementioned concealed vision protection posture correction table is stored, the limiting member 1 is arranged parallel to the bottom surface of the mounting reference 3. The second usage process of the aforementioned concealed vision protection posture correction table is as follows:

[0071] When needed, rotate the limiting member 1 (which is in a hidden state) located directly below the mounting reference 3 by 90°. At this time, the limiting member 1 and the base member 2 are on the same straight line, meaning that the limiting member 1 is temporarily hidden. Then rotate the base member 2 so that the base member 2 and the limiting member 1 rotate 180° in the vertical plane, making the side of the limiting member 1 parallel to the side of the mounting reference 3. The limiting member 1 protrudes upward from the top surface of the mounting reference 3, thus converting the limiting member 1 into a usable state, allowing the user to correct their sitting posture.

[0072] When storage is required, the base piece 2 connected to the limit piece 1 in use is rotated 180° in the reverse direction in the vertical plane. At this time, the limit piece 1 is in a temporary hidden position. Then, the limit piece 1 is rotated 90° in the reverse direction (it can be less or greater than 90°) to store the limit piece 1 at the bottom of the mounting base 3. At this time, the limit piece 1 is converted to a hidden state, thus realizing the hiding of the limit piece 1.

[0073] Example 2

[0074] This embodiment discloses a hidden vision protection posture correction table. Based on embodiment 1, the difference between this embodiment and embodiment 1 is that: in this embodiment, a first notch 32 is provided on the mounting reference 3; in this embodiment, the mounting part 4 is removed, and at least part of the base part 2 is directly embedded into the first notch 32 and rotatably connected to the mounting reference 3.

[0075] In this embodiment, removing the mounting component 4 simplifies the overall structure of the device, making it easier for users to operate and maintain. Furthermore, when the mounting component 4 is installed, there is a situation where the mounting component 4 partially protrudes downwards from the mounting reference 3; when the mounting component 4 is removed and the base component 2 is directly installed into the first notch 32, the base component 2 will not protrude downwards from the mounting reference 3, further optimizing the overall concealment effect of the device and making the device more aesthetically pleasing.

[0076] Example 3

[0077] This embodiment discloses a hidden vision protection posture correction table. Based on embodiment 1, the difference between this embodiment and embodiment 1 is that this embodiment introduces a sliding component, which further optimizes the storage and unfolding mechanism of the limiting component 1.

[0078] More specifically, the base component 2 is rotatably mounted on the sliding assembly, and the sliding assembly is in sliding engagement with the mounting reference 3.

[0079] When the limiting member 1 changes from the first state to the second state, the sliding component drives the base member 2 and the limiting member 1 to extend from the side of the mounting reference 3 along the first direction. As a result, when the limiting member 1 is flipped, there will be no interference between the limiting member 1 and the mounting reference 3, ensuring that the limiting member 1 can be flipped smoothly.

[0080] When the limiting member 1 transitions from the second state to the first state, after the limiting member 1 rotates around the second plane to below the mounting reference 3, the sliding assembly drives the base member 2 and the limiting member 1 to slide and be housed below the mounting reference 3 along the second direction. The first direction is opposite to the second direction.

[0081] Thanks to the sliding component, the device can better adapt to changes in different desktop heights and shapes, making it suitable for more complex work and life scenarios.

[0082] As one specific embodiment, the sliding component includes a slide rail, and the base component 2 is provided with a sliding part adapted to the slide rail.

[0083] As a further improved implementation, the slide rail can be straight, curved, or polygonal. The specific shape and specifications of the slide rail can be arranged according to the actual shape and specifications of the mounting reference 3, so that the limiting member 1 can be stored and hidden in the designated position on the bottom surface of the mounting reference 3 after moving along the slide rail. For example, after the limiting member 1 completes the second flip, it slides along the obliquely set slide rail to the corner position of the mounting reference 3, thereby making the posture platform as a whole far away from the position of a normally seated human body, which can effectively avoid the situation where the posture platform as a whole touches the human body after being stored.

[0084] As a further improved implementation, the base component 2 moves along the slide rail under the drive of an electric drive structure or a manual adjustment handle, making the sliding of the base component 2 and the limiting component 1 more convenient. For example, when the slide rail is a linear slide rail, a lead screw can be arranged inside the slide rail, and a lead nut can be arranged on the sliding part. The lead screw and the lead nut are fitted together, and a motor is provided at the end of the lead screw. When the motor is running, the motor can drive the lead screw to rotate, thereby driving the lead nut, the base component 2, and the limiting component 1 to move to the designated position. This method can be applied to situations where the position where the posture aligning table needs to be stored is far from the side of the mounting reference 3, making manual operation inconvenient. In addition, the base component 2 and the limiting component 1 can also be directly pushed along the slide rail by a manual adjustment handle.

[0085] Example 4

[0086] This embodiment discloses a hidden vision protection posture correction table. The difference between this embodiment and embodiment 1 is that the base component 2 is set to be retractable.

[0087] When the limiting member 1 transitions from the first state to the second state, the base member 2 extends to allow the limiting member 1 to extend from the side of the mounting reference 3. This prevents the limiting member 1 from contacting the mounting reference 3 during rotation, reducing interference from the mounting reference 3 during rotation. When the limiting member 1 transitions from the second state to the first state, after rotating around the second plane to below the mounting reference 3, the base member 2 retracts to house the limiting member 1 below the mounting reference 3.

[0088] More specifically, the base component 2 can be divided into a body part and a mounting part, with a telescopic rod provided between the body part and the mounting part. When the mounting part is pulled, the mounting part can move along the direction of the telescopic rod. The direction of the telescopic rod is perpendicular to the side of the mounting reference 3, or the direction of the telescopic rod is at a certain angle to the side of the mounting reference 3. Thus, when the telescopic rod extends, the limiting member 1 can extend from the side of the mounting reference 3, avoiding interference between the limiting member 1 and the side of the mounting reference 3 when rotating.

[0089] Example 5

[0090] This embodiment discloses a concealed vision protection posture correction table. Based on any of the embodiments in Embodiments 1-4, the difference between this embodiment and Embodiments 1-4 is that: the base component 2 and the mounting reference 3 are detachable; and / or, the limiting component 1 and the base component 2 are detachable.

[0091] In this embodiment, the base component 2 and the mounting reference 3 are designed to be detachable, so that when the base component 2 and / or the mounting reference 3 are damaged, they can be removed and replaced.

[0092] Example 6

[0093] This embodiment discloses a concealed vision protection posture correction table, combined with Figures 3 to 7 As shown, based on any of the embodiments in Examples 1-5, the difference between this embodiment and Examples 1-5 is that a first receiving cavity 22 is provided through the side wall of the base component 2, and a second receiving cavity 31 is provided on the mounting reference 3. When the base component 2 is in the first position and the limiting component 1 is in the third position, the axis of the first receiving cavity 22 is collinear with the axis of the second receiving cavity 31, and the first receiving cavity 22 and the second receiving cavity 31 are connected, so that the limiting part of the limiting component 1 is housed in the second receiving cavity 31 of the mounting reference 3.

[0094] In this embodiment, by designing the axis of the first receiving cavity 22 to be collinear with the axis of the second receiving cavity 31, the limiting member 1 can flexibly switch positions between the base member 2 and the mounting reference 3. When the limiting member 1 is not needed, it can be completely or partially housed within the second receiving cavity 31 of the mounting reference 3, reducing the space occupied.

[0095] Example 7

[0096] Secondly, this embodiment discloses a vision protection posture correction table, including mounting reference 3 and a hidden vision protection posture correction table in any of the embodiments 1-6.

[0097] Mounting reference 3 can be any of a table, tabletop, or table clamp, meeting the needs of increasingly diverse learning scenarios. When a table is used as mounting reference 3, it has supporting legs at its base. The table can be of any suitable shape and size to adapt to different usage environments and user needs. When a tabletop is used as mounting reference 3, it can be fixed or height- and tilt-adjustable to provide greater flexibility. Table clamps are suitable for fixing concealed vision protection posture correctors to existing tables or flat surfaces, allowing for easy installation and use without any modifications to the table.

[0098] At least one concealed posture correction stand is provided and installed on mounting base 3 to correct the user's sitting posture. When correcting the user's posture, the base component 2 of the concealed posture correction stand can be flipped to the second position, and the limiting component 1 can be flipped to the fourth position. The limiting component 1 guides the user back to the correct sitting posture, which not only helps protect the user's vision health, but also effectively prevents health problems such as cervical and lumbar spine caused by improper sitting posture for a long time.

[0099] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
