Description

Technical Field

[0001] This utility model relates to the field of learning aids technology, and in particular to an ergonomic eye-protection table suitable for multiple scenarios. Background Technology

[0002] Students often bend over, hunch their necks, or hunch over their desks while studying. If they maintain these incorrect postures for a long time, they can develop bad reading and writing habits. On the one hand, this can easily lead to spinal deformities, and on the other hand, it can greatly increase the probability of children developing myopia or worsening their myopia. Adolescents are in a critical period of growth and development, and this will inevitably have irreversible negative effects on their vision and normal physical development. Therefore, it is especially important to ensure that students maintain correct posture in various learning scenarios.

[0003] Posture correctors are assistive devices that guide users' sitting posture in various scenarios such as learning, writing, and office work, including reading, writing, and handicrafts. Common posture correctors include a reference board and an orthotic device placed on the side of the reference board closest to the user's sitting posture. Currently, in order to provide users with more scientific and precise posture guidance in various learning scenarios, the reference board of existing posture correctors can be placed horizontally to meet the needs of handicrafts, or it can be placed at a certain angle to the horizontal plane to meet the needs of writing or reading. Under the needs of multiple usage scenarios, the orthotic device is difficult to correct and guide sitting posture. Utility Model Content

[0004] The main purpose of this invention is to propose an ergonomic eye-protection table for multiple scenarios, aiming to improve the problem of difficulty in correcting and guiding sitting posture.

[0005] To achieve the above objectives, this utility model proposes an ergonomic eye-protection table suitable for multiple scenarios, comprising:

[0006] A reference plate, the upper surface of which has a working surface formed, the tilt angle of which is adjustable; and,

[0007] The corrective component is located on the sitting posture correction side of the reference plate. The corrective component has a correction position and a reference line relative to the reference plate. The reference line extends along the length direction of the corrective component.

[0008] Wherein, when the corrector is in the corrected position, the angle A between the reference line of the corrector and the working surface satisfies: A < 90°.

[0009] In one embodiment, the corrective member includes a support portion connected to a reference plate and a corrective portion connected to the support portion. When the corrective member is in the corrective position, the orthographic projection of the side of the corrective portion away from the reference plate in the vertical direction is at least partially located outside the reference plate.

[0010] In one embodiment, the angle A between the reference line of the straightening element and the working surface satisfies: 82.5° ≤ A ≤ 84°; and / or,

[0011] The angle B between the working surface and the horizontal plane satisfies: 0°≤B≤15°.

[0012] In one embodiment, the angle A between the reference line of the straightening element and the working surface satisfies: A = 84°, and during the adjustment of the tilt angle of the working surface:

[0013] The working surface has a first position, and when the working surface is in the first position, the angle B between the working surface and the horizontal plane is 0°; and / or,

[0014] The working surface has a second position, and when the working surface is in the second position, the angle B between the working surface and the horizontal plane is 7°; and / or,

[0015] The working surface has a third position, and when the working surface is in the third position, the angle B between the working surface and the horizontal plane is 12°.

[0016] In one embodiment, the maximum angle between the reference line of the straightening element and the vertical line is C1, and the maximum angle between the working surface and the horizontal plane is B1, wherein the angle of B1 is twice the angle of C1.

[0017] In one embodiment, the straightening member is rotatably mounted on the reference plate along an axis extending in a first direction to adjust the angle A between the reference line of the straightening member and the working surface.

[0018] In one embodiment, when the straightening member is in the straightening position, during the adjustment of the tilt angle of the working surface, the included angle A between the reference line of the straightening member and the working surface remains fixed.

[0019] In one embodiment, the corrective component includes a rotating part, which is rotatably disposed on the reference plate along an axis extending in a first direction. The corrective component is rotatably connected to the reference plate through the rotating part. The ergonomic multi-scenario eye protection platform also includes a locking structure, which locks the rotation of the rotating part when the corrective component is in the corrective position.

[0020] In one embodiment, the corrector further includes a first limiting part, and the reference plate includes a second limiting part. When the corrector is in the corrected position, the first limiting part and the second limiting part abut against each other to block the rotation of the corrector toward the working surface.

[0021] In one embodiment, the corrective member includes a rotating part, which is rotatably disposed on the reference plate along an axis extending in a first direction. The corrective member is rotatably connected to the reference plate through the rotating part, and a reference surface is formed with the rotation axis of the rotating part as a reference. When the corrective member is in the corrective position, the reference surface is perpendicular to the working surface.

[0022] The reference line of the straightening component is located within the angle between the reference plane and the working surface.

[0023] The support portion is parallel to the baseline of the corrective element; or,

[0024] In one embodiment, the support extends in a curve, and the line connecting the two ends of the support is parallel to the baseline.

[0025] In the technical solution of this utility model, during use, the corrective component is placed in the corrective position, and the reference plate is operated. Usually, the height of the end of the reference plate facing away from the sitting posture correction side is raised, so that the tilt angle of the working surface can be adjusted. At this time, the corrective component installed on the reference plate swings towards the user side as the reference plate is raised. When the reference plate is flat, the angle between the reference line and the working surface is the same as the angle between the reference line and the horizontal plane. When the reference plate is tilted, the angle between the reference line of the corrector and the horizontal plane also increases. However, by setting the angle A between the reference line of the corrector and the working surface to be acute, and when the tilt angle of the working surface is within a certain range, the reference line of the corrector can be made close to the vertical axis. This reduces the outward tilt of the corrector when the reference plate is tilted, ensuring the corrector's effect on posture correction. This ensures that the corrector is always in a suitable position to guide the user's chest support, thus improving the problem of difficulty in correcting posture caused by the tilt of the reference plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] Students often bend over, hunch their necks, or hunch over their desks while studying. If they maintain these incorrect postures for a long time, they can develop bad reading and writing habits. On the one hand, this can easily lead to spinal deformities, and on the other hand, it can greatly increase the probability of children developing myopia or worsening their myopia. Adolescents are in a critical period of growth and development, and this will inevitably have irreversible negative effects on their vision and normal physical development. Therefore, it is especially important to ensure that students maintain correct posture in various learning scenarios.

[0044] Eye-protection desks provide ergonomic assistive devices for users in various scenarios such as learning, writing, and office work, offering support during activities like reading, writing, and crafts. Common posture correction products include a reference board and an orthotic device positioned on the reference board closest to the user's sitting posture. Currently, to provide more scientific and precise posture guidance for users in various learning scenarios, existing posture correction products' reference boards can be placed horizontally to meet the needs of crafts, or tilted at an angle to the horizontal plane to accommodate writing or reading needs. However, in multiple usage scenarios, the orthotic device struggles to effectively correct and guide sitting posture.

[0045] This invention proposes an ergonomic eye-protection table suitable for multiple scenarios.

[0046] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, a reference plate 1 and a corrective member 2 are included. A working surface 11 is formed on the upper surface of the reference plate 1, and the tilt angle of the working surface 11 is adjustable. The corrective member 2 is located on the sitting posture correction side of the reference plate 1, and the corrective member 2 has a correction position. The corrective member 2 has a reference line 3 relative to the reference plate 1, and the reference line 3 extends along the length direction of the corrective member 2. When the corrective member 2 is in the correction position, the included angle A between the reference line 3 of the corrective member 2 and the working surface 11 satisfies: A < 90°.

[0047] In the technical solution of this utility model, when the corrective component 2 is in the corrective position, rotating the reference plate 1 can adjust the tilt angle of the working surface 11. The corrective component 2 can move with the reference plate 1, thereby changing the angle between the reference line 3 and the horizontal plane 6. When the tilt angle of the working surface 11 is within a certain range, the reference line 3 of the corrective component 2 can be close to the vertical axis, which can ensure the corrective effect of the corrective component 2 on the sitting posture, so that the corrective component 2 can be adaptively pressed against the chest, and the problem of difficulty in correcting and guiding the sitting posture can be improved as a whole.

[0048] During use, the corrector 2 is placed in the corrective position, and the reference plate 1 is operated. Usually, the height of the end of the reference plate 1 facing away from the sitting posture correction side is raised, so that the tilt angle of the working surface 11 can be adjusted. At this time, the corrector 2 installed on the reference plate 1 swings towards the user side as the reference plate 1 is raised. When the reference plate 1 is in a flat position, the angle between the reference line 3 and the working surface 11 is the angle between the reference line 3 and the horizontal plane 6. When the reference plate 1 is tilted, the angle between the reference line 3 of the corrector 2 and the horizontal plane 6 will also increase. However, by setting the angle A between the reference line 3 of the corrector 2 and the working surface 11 to be an acute angle, when the tilt angle of the working surface 11 is within a certain range, the reference line 1 of the corrector 2 can be made close to the vertical axis, thereby reducing the outward tilt of the corrector 2 when the reference plate 1 is tilted. This ensures the corrector 2's effect on posture correction, so that the corrector 2 can always be in a suitable position to guide the user's chest support. Overall, this improves the problem of difficulty in correcting and guiding posture caused by the tilt of the reference plate 1.

[0049] During reading, writing, and craft activities, the orthotic piece 2, placed against the chest, reduces forward leaning of the upper body, maintaining an upright posture and correcting the sitting posture to conform to ergonomics. This reduces spinal deformation during activities such as reading, writing, and crafts. By reducing upper body tilt, the eyes and work surface 11 are kept at a suitable distance, reducing the probability of myopia or its progression in children, thus protecting their vision. Furthermore, by setting the work surface 11 to a tiltable position, downward eye movement is reduced, allowing users (such as children) to maintain a level gaze and reducing eye strain.

[0050] In this embodiment, the reference plate 1 is the tabletop of the ergonomic multi-scenario eye protection table, and the reference line 3 is a line segment or straight line extending along the length direction of the corrector 2, with the extension of the reference line 3 passing through the connection point between the corrector 2 and the reference plate 1. When the work surface 11 is horizontal, manual tasks can be completed on the work surface 11; when the work surface 11 is inclined, books can be placed on the work surface 11, thus facilitating reading.

[0051] During the use of the ergonomic eye-protecting desk in various scenarios, by placing the corrector 2 in the corrective position, the height of the corrector 21 can be made higher than the working surface 11, and the corrector 21 of the corrector 2 rests against the chest, so as to reduce forward leaning when reading and writing and achieve the correction of sitting posture.

[0052] The corrective component 2 includes a corrective component 2 connected to the reference plate 1 and a corrective part 21 connected to the corrective component 2. When the corrective component 2 is in the corrective position, the orthographic projection of the side of the corrective part 21 away from the reference plate 1 in the vertical direction is at least partially located outside the reference plate 1. When using the ergonomic multi-scenario eye protection platform, the side of the corrective part 21 away from the reference plate 1 can be pressed against the chest to prevent the user's chest from being placed directly above the reference plate 1, thereby reducing the user's forward tilting on the reference plate 1.

[0053] In this embodiment, the corrective component 2 is rotatably mounted on the reference plate 1 along an axis extending in a first direction. Specifically, the first direction extends along the length of the reference plate 1, and is parallel to the length of the working surface 11, that is, with the eye-protecting table placed in front of the user during normal use as a reference, parallel to the user's shoulder. The corrective component 2 and the reference plate 1 can be rotatably connected through a shaft hole. The corrective component 2 and the reference plate 1 can be infinitely adjustable or stepped adjustable. The ergonomic multi-scenario eye-protecting table also includes a locking structure, which locks the rotation of the rotating part 22. Specifically, the locking structure can be a bolt; after the corrective component 2 rotates to a predetermined position, the rotation of the corrective component 2 can be locked by tightening the bolt.

[0054] When the corrector 2 is in the corrected position, during the adjustment of the tilt angle of the working surface 11, the included angle A between the reference line 3 of the corrector 2 and the working surface 11 remains fixed. By keeping the included angle between the reference line 3 of the corrector 2 and the working surface 11 fixed, adaptive adjustment of the corrector 2 can be achieved when adjusting the tilt angle of the working surface 11.

[0055] Please see Figure 3 , Figure 4 and Figure 5 The included angle A between the reference line 3 of the corrective component 2 and the working surface satisfies: 82.5°≤A≤84°. When the working surface 11 is kept horizontal, the included angle A between the reference line 3 of the corrective component 2 and the working surface is at least 82.5°, and the included angle A between the reference line 3 of the corrective component 2 and the vertical line 4 is at most 84°. This allows the reference line 3 of the corrective component 2 to be close to the vertical line 4, thereby ensuring the corrective effect of the corrective component 2 on sitting posture.

[0056] When the corrector 2 is in the corrected position, the angle A between the reference line 3 of the corrector 2 and the working surface can satisfy any value among 82.5°, 83°, 83.5° and 84°, and the angle A between the reference line 3 of the corrector 2 and the working surface can be any value between any two of the above values.

[0057] The angle B between the working surface 11 and the horizontal plane 6 satisfies: 0°≤B≤15°. Adjusting the working surface 11 can adjust the angle between the working surface 11 and the horizontal plane 6 to adapt to various usage scenarios of the ergonomic multi-scenario eye protection table.

[0058] During the angle adjustment process of the working surface 11, the angle B between the working surface 11 and the horizontal plane 6 satisfies any one of the following values: 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, and 15°, and the angle B between the working surface 11 and the horizontal plane 6 can be any value between any two of the above values.

[0059] The reference plate 1 can rotate in stages around an axis extending in a first direction, so that the tilt angle of the working surface 11 is adjustable. The rotation of the reference plate 1 can be any staged rotation method in the prior art. By rotating the reference plate 1 to different angles, the tilt angle of the working surface 11 can be adjusted.

[0060] Please see Figure 1 and Figure 2 The angle A between the reference line 3 of the corrector 2 and the working surface 11 satisfies: A = 84°. During the adjustment of the tilt angle of the working surface 11, the working surface 11 has a first position. When the working surface 11 is in the first position, the angle B between the working surface 11 and the horizontal plane 6 is 0°. At this time, the angle C between the reference line 3 and the vertical line 4 is 6°, which ensures the correction of the sitting posture by the corrector 21 during manual operation.

[0061] Please see Figure 3 , Figure 4 and Figure 5 The angle A between the baseline 3 of the corrective element 2 and the working surface 11 satisfies: A = 84°. During the adjustment of the tilt angle of the working surface 11, the working surface 11 has a second position. When the working surface 11 is in the second position, the angle B between the working surface 11 and the horizontal plane 6 is 7°; at this time, the angle C between the baseline 3 and the vertical line 4 is 1°, which can ensure the correction of posture by the corrective element 21. By setting the working surface 11 in the second position, it is convenient to place the work on the working surface 11, thereby correcting the posture during the writing process. It is also convenient to place the book on the working surface 11, thereby correcting the posture during the reading process.

[0062] Please see Figure 6 , Figure 7 and Figure 8The angle A between the baseline 3 of the corrective component 2 and the working surface 11 satisfies: A = 84°. During the adjustment of the tilt angle of the working surface 11, the working surface 11 has a third position. When the working surface 11 is in the third position, the angle B between the working surface 11 and the horizontal plane 6 is 12°, and the angle C between the baseline 3 and the vertical line 4 is 6°, which can ensure that the corrective component 21 can correct the sitting posture. By setting the working surface 11 in the third position, it is convenient to place the book on the working surface 11, thereby correcting the sitting posture during reading.

[0063] During the adjustment of the tilt angle of the working surface 11: the working surface 11 has a first position, a second position, and a third position. When the working surface 11 is in the first position, the angle B between the working surface 11 and the horizontal plane 6 is 0°; when the working surface 11 is in the second position, the angle B between the working surface 11 and the horizontal plane 6 is 7°; when the working surface 11 is in the third position, the angle B between the working surface 11 and the horizontal plane 6 is 12°. By presetting the first, second, and third positions, the working surface 11 can be easily adjusted to any one of the first, second, and third positions as needed.

[0064] The angle between the reference line 3 and the vertical line 4 of the corrector 2 is C, and the angle between the working surface 11 and the horizontal plane 6 is B. When the corrector 2 is in the corrected position, during the process of the change of the tilt angle of the working surface 11, the maximum angle between the reference line and the vertical line of the corrector is C1, and the maximum angle between the working surface and the horizontal plane is B1, wherein the angle of B1 is twice the angle of C1.

[0065] Specifically, the angle A between the reference line of the straightening component and the working surface satisfies: A = 82.5°, and when the maximum angle B1 between the working surface 11 and the horizontal plane 6 is 15°, the angle C1 between the reference line 3 and the vertical line 4 is 7.5°. The angle A between the reference line of the straightening component and the working surface satisfies: A = 84°, and when the maximum angle B1 between the working surface 11 and the horizontal plane 6 is 12°, the angle C1 between the reference line 3 and the vertical line 4 is 6°.

[0066] To increase the number of intermediate points for adjusting the tilt angle of the working surface 11, the reference plate 1 rotates steplessly around an axis extending in the first direction. The stepless rotation of the reference plate 1 can be any existing stepless rotation structure, and is not limited here.

[0067] The corrector 2 is rotatably mounted on the reference plate 1 along an axis extending in the first direction to adjust the angle A between the reference line 3 of the corrector 2 and the working surface 11. Before use, the corrector 2 can be adjusted to the corrected position by rotating it; after use, the corrector 2 can be rotated to store it.

[0068] The corrective component 2 includes a rotating part 22, which is rotatably mounted on the reference plate 1 along an axis extending in a first direction. The corrective component 2 is rotatably connected to the reference plate 1 via the rotating part 22. The ergonomic multi-scenario eye protection platform also includes a locking structure. When the corrective component 2 is in the corrective position, the locking structure locks the rotation of the rotating part 22. The rotating part 22 can be a rotating seat, and the rotating seat and the reference plate 1 can be rotatably connected through a shaft hole. The locking structure is a bolt that tightens the rotation of the rotating part 22. The locking structure can also be a snap-fit ​​mechanism to lock the rotation of the rotating part 22; no limitation is made here.

[0069] To pre-set the rotational position of the rotating part 22 and thus position the corrector 2 in a predetermined manner, the rotation of the rotating part 22 about an axis extending in the first direction is a stepped rotation. The stepless rotation of the rotating part 22 can be any existing stepped rotation structure, and is not limited here.

[0070] The rotation of the rotating part 22 around the axis extending in the first direction is a stepless rotation. This increases the adjustable position of the corrector 2, allowing the rotating part 22 to be adjusted to a corresponding position as needed. The stepless rotation of the rotating part 22 can be any existing stepless rotation structure, and is not limited here.

[0071] Reference Figure 1 , Figure 9 and Figure 10 The corrector 2 further includes a first limiting part 221, and the reference plate 1 includes a second limiting part 12. When the corrector 2 is in the corrected position, the first limiting part 221 and the second limiting part 12 abut against each other to block the rotation of the corrector 2 toward the working surface 11. When the corrector 2 is in the corrected position, the first limiting part 221 and the second limiting part 12 abut against each other to improve the stability of the corrector 2 and reduce the shaking of the corrector 2. The first limiting part 221 is the outer surface of the rotating part 22, and the second limiting part 12 is the outer surface of the reference plate 1.

[0072] When the corrector 2 is in the corrected position, by recessing the second limiting portion 12 away from the first limiting portion 221, or by recessing the first limiting portion 221 away from the second limiting portion 12, the reference line 3 forms an acute angle with the working surface 11 when the first limiting portion 221 and the second limiting portion 12 abut. Alternatively, the shape and position of the first limiting portion 221 and the second limiting portion 12 can be configured such that the angle between the reference line 3 and the working surface 11 forms an acute angle when the first limiting portion 221 and the second limiting portion 12 abut.

[0073] Please see Figure 1 and Figure 2 The straightening component 2 includes a rotating part 22, which is rotatably mounted on the reference plate 1 along an axis extending in a first direction. The straightening component 2 is rotatably connected to the reference plate 1 via the rotating part 22, and a reference surface is formed with the rotation axis of the rotating part 22 as a reference. When the straightening component 2 is in the straightening position, the reference surface 5 is perpendicular to the working surface 11. The reference line 3 of the straightening component 2 is located within the angle between the reference surface 5 and the working surface 11. Thus, by controlling the rotating part 22 of the straightening component 2, the reference line 3 of the straightening component 2 maintains an acute angle with the working surface 11, eliminating the need for additional complex structures and reducing processing difficulty.

[0074] The reference plane 5 is a plane passing through the rotation axis of the rotating part 22, and the reference plane 5 rotates with the rotating part 22. Specifically, when the angle of the working surface 11 remains unchanged, the corrector 2 is moved and the corrector 2 is placed in the corrected position, the reference plane 5 is perpendicular to the working surface.

[0075] The support portion 23 is parallel to the reference line 3 of the straightening member 2; ensuring the connection between the support portion 23 and the rotating portion 22 and the straightening portion 21, the length of the support portion 23 can be reduced, thereby reducing the material used in the support portion 23. Specifically, the support portion 23 is coaxial with the reference line 3 of the support portion 23. The support portion 23 can be connected to the edges of the straightening portion 21 and the rotating portion 22 respectively, such that the reference line 3 is offset from the support portion 23, or the reference line 3 is located outside the support portion 23.

[0076] The support portion 23 extends in a curve, and the line connecting the two ends of the support portion 23 is parallel to the reference line 3. While ensuring the connection between the support portion 23 and the rotating portion 22 and the straightening portion 21, the shape of the support portion 23 can be modified according to requirements by setting the support portion 23 to a curved structure.

[0077] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
