Description

Technical Field

[0001] This application relates to the field of posture correction technology, specifically to a posture corrector for a streamlined writing board. Background Technology

[0002] In recent years, parents have placed great emphasis on students' learning. Because elementary school students have low self-control, they often develop poor posture while writing and reading, which can lead to myopia and other eye problems. Currently, posture correctors are popular with parents because they can correct students' poor posture during learning and prevent myopia. However, existing posture correctors often have a flat, upright design with an angled surface. This allows items placed on the writing board (such as books or tablets) to slide down due to gravity, resulting in a poor user experience. Utility Model Content

[0003] Therefore, the technical problem to be solved by this application is to overcome the shortcomings of the existing posture correctors. In the design and manufacturing process, the entire writing board is designed as a straight board, and the writing board is tilted relative to the desktop. The surface of the writing board is often relatively smooth. Items placed on the writing board (such as books, tablets, etc.) will slowly slide down the writing board due to gravity, resulting in a poor user experience.

[0065] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0068] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0069] According to some embodiments of this application, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the posture corrector 100 of the streamlined writing tablet in some embodiments of this application. Figure 2 This is a schematic diagram of the streamlined writing tablet posture corrector 100 with some structures removed in some embodiments of this application. The embodiments of this application provide a streamlined writing tablet posture corrector 100, which includes a writing tablet 110. The writing tablet 110 has a writing area and a wrist rest area. The writing area has a writing surface W, which is suitable for placing items. The wrist rest area is close to the user setting. The writing area and the wrist rest area together form an upward-facing first streamlined curved surface M1.

[0070] The writing board 110 is the main structure constituting the posture corrector 100 of the streamlined writing board. The writing area is the main area on the writing board 110 used to facilitate writing, drawing, and other operations by the user. The wrist rest area is the area on the writing board 110 used to rest the wrist and / or elbow. The writing area and the wrist rest area each have an upward-facing upper surface. The upward-facing upper surface of the writing area includes the writing surface W. The upper surfaces of the writing area and the wrist rest area can also be considered as user-facing surfaces, meaning surfaces that directly contact the user's body or operating behavior during use. In other words, a user-facing surface is not necessarily the surface directly opposite the user.

[0071] Streamlined design is a design form characterized by smooth, curved contours. The first streamlined surface M1 refers to a surface with a streamlined design. When a surface has a streamlined design, it lacks sharp edges, abrupt protrusions, or sudden depressions. This ensures that the user experiences no noticeable stinging or gritty sensation when in contact with the first streamlined surface M1. Furthermore, because the first streamlined surface M1 has a certain curvature, it helps to conform to the natural shape of the user's contact area (such as the lines of the wrist and / or elbow). When discussing other implementations of streamlined surfaces later, the first streamlined surface M1 can be used as a reference for understanding, and will not be elaborated upon further.

[0072] The first streamlined curved surface M1 can prevent objects from falling from the writing board 110 onto the table or the floor. Taking the writing area of ​​the writing board 110 placed at an angle on the table as an example, when an object falls along the writing area, the formation of the first streamlined curved surface M1 not only increases the contact area to improve friction, but also decomposes the downward force through the curvature of the surface. In other words, the geometric shape of the first streamlined curved surface M1 is used to improve the force environment of the object, thereby reducing the risk of the object falling from the writing area onto the table or the floor. It can be understood that when the writing area of ​​the writing board 110 is not placed at an angle, the first streamlined curved surface M1, being a surface with a streamlined design, can also prevent objects from falling from the writing board 110 onto the table or the floor. No specific limitations are made here.

[0073] Therefore, in this embodiment of the application, the writing board 110 is configured to include a writing area and a wrist rest area near the user, so that the writing area and the wrist rest area together form an upward-facing first streamlined curved surface M1. When an item moves on the writing board 110, the presence of the first streamlined curved surface M1 will prevent the item from falling from the writing board 110 onto the table or the ground, thus providing the user with a better user experience.

[0074] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2The wrist guard area is provided with a horizontal wrist guard plate 111. The horizontal wrist guard plate 111 has an upwardly facing horizontal wrist guard surface H. One side of the horizontal wrist guard surface H is connected to the writing surface W. The writing surface W and the horizontal wrist guard surface H form a first streamlined curved surface M1.

[0075] The term "horizontal" in "horizontal wrist rest 111" reflects the spatial position of the wrist rest 111, while "wrist support" reflects its primary functional attribute. The lateral direction of the wrist rest 111 refers to the direction that matches the user's operating posture. Taking a normal seated writing posture as an example, with the user's body facing the writing surface W and the arm naturally placed on the edge of the writing pad 110, the lateral direction is roughly parallel to the direction of the user's forearm or wrist. For example, if the writing pad 110 is tilted forward or backward, the lateral direction can be horizontal.

[0076] The upward-facing surface of the horizontal wrist guard 111 is called the horizontal wrist guard surface H. The horizontal wrist guard surface H is the surface of the horizontal wrist guard 111 that primarily supports the user's wrist and / or elbow.

[0077] Thus, by setting up a horizontal wrist rest 111, it is easier to match the user's operating posture, thereby further improving the wrist support performance and user comfort. The horizontal wrist rest 111 can be used to support the wrist and / or elbow, improving the wrist or elbow from being suspended in the air, enhancing the comfort of using the writing tablet 110, assisting the user in maintaining a correct posture, achieving longer periods of posture maintenance, correcting poor sitting posture, effectively preventing myopia, and achieving the purpose of protecting the spine and eyes.

[0078] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing surface W is inclined to the horizontal plane, and the first streamlined curved surface M1 is used to prevent items from falling along the writing area onto the table or the ground.

[0079] The horizontal plane can be understood as the desktop of the tabletop. The writing surface W is tilted relative to the horizontal plane; that is, when the posture corrector 100 of the streamlined writing board is placed on the desktop, the writing surface W is tilted. For example, the writing surface W can be tilted due to the structure of the writing board 110 itself, or it can be tilted by supporting the writing board 110 with related components. For example, the related component can be the support structure 130 shown later.

[0080] For example, in conjunction with reference Figure 1 and Figure 2 The writing surface W is tilted, which can be seen as an upward extension of the writing surface W away from the wrist guard area.

[0081] Thus, when an item descends along the writing surface W of the writing board 110, the presence of the first streamlined curved surface M1 will prevent the item from descending, thereby providing the user with a better user experience.

[0082] According to some embodiments of this application, the writing board 110 is adapted to be placed on a tabletop.

[0083] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 has a side wrist guard 112 on each side. The side wrist guard 112 has an upward-facing side wrist guard surface C, which constitutes part of the first streamlined curved surface M1.

[0084] For example, the direction from one side of the writing pad 110 to the other side of the writing pad 110 intersects with the direction from the side of the writing area away from the user to the side of the writing area facing the user. For example, the direction from one side of the writing pad 110 to the other side of the writing pad 110 is perpendicular to the direction from the side of the writing area away from the user to the side of the writing area facing the user.

[0085] The term "lateral" in lateral wrist guard 112 refers to the spatial orientation of lateral wrist guard 112. Unlike the lateral extension of horizontal wrist guard 111, lateral wrist guard 112 is located on both sides of writing board 110. The direction from one side of writing board 110 to the other side of writing board 110 can be roughly considered as the lateral extension direction of horizontal wrist guard 111. When the lateral direction is horizontal, lateral wrist guard 112 is located on the left and right sides of writing board 110, forming an enclosure or extension of the left and right sides of writing board 110.

[0086] The "wrist support" in the lateral wrist brace 112 reflects its main functional attribute. In combination with the spatial position of the lateral wrist brace 112, the lateral wrist brace 112 mainly provides support for the side of the user's wrist and the edge of the forearm.

[0087] The upward-facing surface of the side wrist rest 112 is called the side wrist rest surface C. The side wrist rest surface C is the surface on the side wrist rest 112 that primarily supports the side of the user's wrist and the edge of their forearm. The side wrist rest surface C forms part of the first streamlined curved surface M1; that is, one side of the side wrist rest surface C can smoothly connect with the lateral wrist rest surface H and / or the writing surface W, without specific limitations. Specific understanding can be based on the various structures of the writing board 110 in some embodiments, without specific limitations here.

[0088] Thus, by setting the side wrist guard 112, the writing board 110 can provide edge support for the user on both sides, thereby providing the user with a wider range of use, which is conducive to providing more support for the user's wrist and / or elbow, and can further adapt to the natural trajectory of the wrist's left and right movement, reduce lateral fatigue, and further improve the comfort and stability when writing, drawing and other operations.

[0089] During use, the user's arm is outstretched. Therefore, the lateral wrist guard 112 can provide sufficient support for the user's arm, prevent partial suspension, and provide a more stable posture support effect.

[0090] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 A second streamlined curved surface M2 is formed between the lateral wrist guard 112 and the writing board 110.

[0091] by Figure 1 and Figure 2 For example, one side of the writing board 110 with a side wrist rest 112 includes a portion connected to the side wrist rest 112, and another portion other than the portion connected to the side wrist rest 112. This other portion forms a second streamlined curved surface M2 with the side surface of the writing board 110 opposite to the side wrist rest 112.

[0092] For example, the side of the lateral wrist rest 112 may have a lateral curved surface, and the side of the writing pad 110 may have a straight surface. The straight surface of the writing pad 110 and the lateral curved surface of the lateral wrist rest 112 may form a second streamlined curved surface M2. Of course, the side of the writing pad 110 may also have a lateral curved surface, and no specific limitation is made here.

[0093] Compared to the writing tablet 110, whose sides are entirely composed of straight lines and sharp angles, the second streamlined curved surface M2 eliminates sharp edges and corners that create a gritty feel. This allows the curved surface to better adapt to the body's movements when the user touches the edge, such as when moving or placing objects. This reduces stress concentration caused by sharp edges and lowers the risk of abrasions and injuries from bumps. Furthermore, the streamlined curved surface also adapts well to the user's natural wrist movement, providing more reliable posture support.

[0094] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The side of the lateral wrist guard 112 has a lateral curved surface, and the side of the writing board 110 and the lateral curved surface of the lateral wrist guard 112 form a second streamlined curved surface M2.

[0095] Since the side wrist guard 112 is close to the user's position, there may be situations where the user touches the side of the side wrist guard 112 when moving their body or placing items. When the side of the side wrist guard 112 has a lateral curved surface, the risk of scratches and abrasions caused by bumps can be further reduced, thereby further improving the safety of use.

[0096] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The side surface of the writing area is a straight surface, and the straight surface of the side surface of the writing area constitutes part of the second streamlined curved surface M2; and / or, the writing board 110 includes a horizontal wrist guard 111 disposed in the wrist guard area, the side surface of the horizontal wrist guard 111 is a curved surface, and the curved surface of the side surface of the horizontal wrist guard 111 constitutes part of the second streamlined curved surface M2.

[0097] By setting the side surface of the writing area to a straight surface, it is easier to process and manufacture compared to curved or irregularly shaped sides. By setting the side surface of the horizontal wrist guard 111 to a curved surface, and making the curved surface of the side surface of the horizontal wrist guard 111 form part of the second streamlined curved surface M2, the edges of the horizontal wrist guard 111 and the side wrist guard 112 are smoothly connected, which not only eliminates the abruptness of right-angle splicing, but also reduces the risk of scratches caused by the formation of sharp corners.

[0098] It should be noted that the extension direction of the straight surface can be parallel to the direction from the side of the writing area away from the user to the side from the user; in this case, the straight surface can be considered an un-tilted surface. Conversely, the extension direction of the straight surface can also intersect with the direction from the side of the writing area away from the user to the side from the user; in this case, the straight surface can be considered a tilted surface. It can be understood that whether the straight surface is tilted or not is relative to the direction from the side of the writing area away from the user to the side from the user.

[0099] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 Along the side of the writing area away from the user, pointing towards the side of the writing area facing the user, the distance between the two second streamlined curved surfaces M2 increases from the lateral wrist guard 112; or

[0100] Along the side of the writing area away from the user, pointing towards the side of the writing area facing the user, the distance between the two second streamlined curved surfaces M2 changes from the side wrist guard plate 112, first increasing and then decreasing.

[0101] The phrase "showing an increasing trend" indicates that the distance between the two second streamlined surfaces M2 generally increases. For example, it could be a continuous increase, or an increase followed by a decrease. "Increase followed by decrease" means that the distance between the two second streamlined surfaces M2 first experiences an increasing phase, then a decreasing phase, but even during the decreasing phase, the distance between the two second streamlined surfaces M2 is still increased compared to the initial distance. The initial distance refers to the distance between the two second streamlined surfaces M2 at the end of the side wrist guard 112 facing away from the user.

[0102] The phrase "showing a trend of first increasing and then decreasing" describes the distance between the two second streamlined surfaces M2 first experiencing an increasing phase and then a decreasing phase. During the decreasing phase, the distance between the two second streamlined surfaces M2 may still be increasing compared to the initial distance mentioned above, or it may not be increasing at all.

[0103] For example, with Figure 1 and Figure 2 For example, along the direction from the side of the writing area away from the user to the side of the writing area facing the user, the distance between the two second streamlined surfaces M2 first increases and then decreases.

[0104] Thus, based on the contact frequency, pressure magnitude, and range of motion of the arm in different areas of the lateral wrist guard 112, the trend of the distance between the two second streamlined curved surfaces M2 can be controlled to make the lateral wrist guard 112 have a certain degree of support while also providing a certain degree of comfort and flexibility.

[0105] It should be noted that in some other embodiments, a second streamlined curved surface M2 may be formed between the lateral wrist guard surface C of the lateral wrist guard plate 112 and the writing board 110. In this case, the lateral wrist guard surface C may form the second streamlined curved surface M2 with the "lateral wrist guard surface H and / or writing surface W". The second streamlined curved surface M2 can be regarded as a part of the first streamlined curved surface M1. This can be understood and implemented according to the specific implementation structure of the writing board 110, and no specific limitations are made here.

[0106] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The surface area of ​​the lateral wrist guard 112 is 3%-15% of the surface area of ​​the writing board 110.

[0107] For example, the surface area of ​​the side wrist guard 112 can be 3%, 4%, 6%, 8%, 10%, 13%, 14%, or 15% of the surface area of ​​the writing board 110. This value can be any value within the range of 3% to 15%, and no specific limitation is made here.

[0108] Thus, the side wrist guard 112 only provides support for the user's elbows or wrists, and does not need to be too large.

[0109] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The cross-section of the first streamlined surface M1 is a curve. The cross-section of the first streamlined surface M1 is a section parallel to the direction from the side of the writing area away from the user to the side of the writing area facing the user.

[0110] For example, such as Figure 1 As shown, the curve can be a smooth curve. A smooth curve is defined as one without sharp inflection points and without abrupt changes in the direction of the tangent.

[0111] Because the cross-section of the first streamlined surface M1 is curved, it extends in a curve from the side away from the user to the side facing the user. This allows the first streamlined surface M1 to be roughly viewed as a curve sweeping along a direction perpendicular to the direction from the side of the writing area away from the user to the side facing the user. Consequently, when an item falls along the writing area, regardless of where it falls, it helps to prevent the item from falling. Furthermore, it also helps to improve user comfort and ease of use when in contact with the first streamlined surface M1. If the cross-section of the first streamlined surface M1 is a smooth curve, it further enhances user comfort and ease of use while preventing the item from falling.

[0112] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The surface parallel to the direction from the side of the writing area away from the user to the side of the writing area facing the user, and intersecting with the first streamlined surface M1, is the reference surface. The intersection of the reference surface and the first streamlined surface M1 is a smooth curve.

[0113] A smooth curve is a line without sharp inflection points and without abrupt changes in the direction of its tangent.

[0114] Because the intersection of the reference surface and the first streamlined surface M1 is a smooth curve, the first streamlined surface M1 extends smoothly from the side away from the user to the side facing the user. This allows the smooth transition surface to be roughly considered as a smooth curve swept along a direction perpendicular to the reference surface. This further enhances user comfort and coordination when in contact with the first streamlined surface M1, thus improving posture correction. Furthermore, when an object falls along the writing area, regardless of where it falls within the writing area, it is more effective at preventing the object from falling.

[0115] It should be noted that, since the first streamlined surface M1 is a surface structure, the cross section of the first streamlined surface M1 can be regarded as the intersection of the aforementioned reference surface and the first streamlined surface M1.

[0116] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The first streamlined curved surface M1 corresponds to the entire wrist guard area and is curved. That is, the upward-facing surface of the wrist guard area is curved.

[0117] Since the wrist rest area is the area on the writing pad 110 used to rest the wrist and / or elbow, when the surface of the wrist rest area facing upward is curved, the curved structure is conducive to adapting to the natural shape of the user's contact part (such as the lines of the wrist and / or elbow), thereby further improving the user's comfort and compliance when the user moves the wrist and / or elbow on the wrist rest area.

[0118] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 includes a horizontal wrist guard plate 111 disposed in the wrist guard area. The horizontal wrist guard plate 111 has an upwardly facing horizontal wrist guard surface H, which is smoothly connected to the writing surface W.

[0119] Smooth connection means that when the horizontal wrist rest surface H and the writing surface W are connected, there are no abrupt turns, obvious height differences, harsh edges, or broken gaps. Instead, they form a seamless whole. For example, when the user's wrist moves between the writing surface W and the horizontal wrist rest surface H, there will be no bumps or jams that feel uncomfortable on the hand.

[0120] Thus, by setting up a smoothly connected horizontal wrist rest surface H and writing surface W, the user's comfort and ease of use can be further improved when the user moves their wrist and / or elbow between the horizontal wrist rest surface H and the writing surface W.

[0121] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The first streamlined surface M1 is concave; or, the first streamlined surface M1 is convex.

[0122] By setting the first streamlined curved surface M1 as a concave surface, the first streamlined curved surface M1 has a certain wrapping and anti-slip ability, which not only helps to prevent items from falling, but also helps to fit the part of the user that contacts the first streamlined curved surface M1, thus improving the user's comfort.

[0123] By setting the first streamlined curved surface M1 as a convex surface, the first streamlined curved surface M1 has a certain guiding and low resistance properties. Thus, when the part of the user that contacts the first streamlined curved surface M1 moves relative to the writing board 110, the raised curvature of the streamlined convex surface can reduce the friction of the contact surface. At the same time, the raised curvature of the streamlined convex surface can also further prevent objects from falling.

[0124] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing surface W is inclined to the horizontal plane, and the writing surface W constitutes part of the first streamlined curved surface M1. The lowest point of the first streamlined curved surface M1 is located in the wrist guard area.

[0125] The lowest point of the first streamlined surface M1 is the lowest point on the first streamlined surface M1. Since the lowest point of the first streamlined surface M1 is located in the wrist rest area, spatially, due to the inclined design of the writing surface W, the writing surface W has an upstream side and a downstream side. The upstream side of the writing surface W can be considered as a higher point in the inclined direction of the writing surface W, and the downstream side of the writing surface W can be considered as a lower point in the inclined direction of the writing surface W. It can be understood that the upstream side of the writing surface W is the side of the writing surface W away from the user, and it is inclined upwards. The downstream side of the writing surface W is the side of the writing surface W closer to the user. Since the wrist rest area is close to the user, it can be considered as being downstream of the downstream side of the writing surface W. Therefore, the lowest point of the first streamlined surface M1 is located in the wrist rest area, which means that the lowest point of the first streamlined surface M1 is downstream of the downstream side of the writing surface W.

[0126] Thus, when the lowest point of the first streamlined curved surface M1 is located in the wrist guard area, if an item falls from the writing surface W, the wrist guard area can be used to further block the item from falling, thereby further reducing the risk of the item falling.

[0127] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The wrist guard area has a protruding end 113 on the side away from the writing area, and the protruding end 113 has a third streamlined curved surface M3 on the side away from the wrist guard area.

[0128] Thus, by utilizing the protruding end 113 to form the third streamlined curved surface M3, not only can the risk of injury to the user be reduced, but the protruding end 113 can also be used to limit the user's movement. At the same time, since the third streamlined curved surface M3 is formed by utilizing the side of the protruding end 113 away from the wrist guard area, the user's arm can be placed at the third streamlined curved surface M3, which can meet the posture correction effect of various user postures.

[0129] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The sides of the protruding end 113 and the wrist guard area are formed by rounded chamfers to create a third streamlined curved surface M3; and / or

[0130] The posture corrector 100 of the streamlined writing board also includes a corrector 120, which is rotatably connected to the protruding end 113.

[0131] The third streamlined curved surface M3 is formed by rounding the corners, which not only reduces the impact of bumps and collisions, protecting the user and the posture corrector 100 of the streamlined writing board, but also makes it more conducive to conforming to the curves of the human body, reducing local pressure, and thus improving the user's comfort when placing their arm on the third streamlined curved surface M3, so as to achieve posture maintenance for a longer period of time.

[0132] The corrector 120 is a functional component that assists the user in maintaining a more correct body posture through physical restraint. Since the protruding end 113 is located on the side of the wrist guard facing the user, the corrector 120 is mounted on the protruding end 113 to directly assist the user in maintaining a correct body posture through physical contact, guiding the user to achieve a fist-sized eye-protection distance between their body and the edge of the table. Simultaneously, the areas on both sides of the protruding end 113 also provide more auxiliary space due to the relative protrusion of the protruding end 113, such as facilitating support and / or accommodating the user's arm, as mentioned above. Because the corrector 120 is rotatably connected to the protruding end 113, it can be rotated above the wrist guard area during posture correction, and can be rotated downwards for storage when not in use, providing more flexibility for various usage scenarios.

[0133] Thus, through the cooperation of the corrective element 120 and the protruding end 113, not only can the correction be more direct and effective, but it can also take into account the comfort and adaptability of use.

[0134] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The protruding end 113 is provided with a receiving groove 1131, which is adapted to be rotatably connected with the rotating end 124 of the straightening member 120.

[0135] For example, in conjunction with reference Figure 3 , Figure 3 This is a schematic diagram of the corrector 120 in some embodiments of this application. The protruding end 113 is provided with a receiving groove 1131. The receiving groove 1131 is adapted to be rotatably connected with the rotating end 124 of the corrector 120. The rotatable connection between the corrector 120 and the writing board 110 is realized through the arrangement of the receiving groove 1131 and the rotating end 124.

[0136] In this way, the position of the corrector 120 can be adjusted to better meet the user's needs.

[0137] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 has an anti-slip structure F on the upper surface corresponding to the wrist guard area. The anti-slip structure F includes an anti-slip strip F1 and / or an anti-slip layer F2.

[0138] For example, with Figure 1 and Figure 2 For example, this illustration shows a case where both the lateral wrist guard 112 and the transverse wrist guard 111 are equipped with anti-slip strips F1. Specifically, both the lateral wrist guard surface C and the transverse wrist guard surface H are equipped with anti-slip strips F1.

[0139] For example, with Figure 4 For example, Figure 4 This is a schematic diagram of the posture corrector 100 of the streamlined writing board in some other embodiments of this application, illustrating the case where the lateral wrist guard 112 has an anti-slip layer F2 and the transverse wrist guard 111 has an anti-slip strip F1. Specifically, the lateral wrist guard surface C is coated with an anti-slip material, and the transverse wrist guard surface H has an anti-slip strip F1.

[0140] Thus, by setting up the anti-slip structure F, the friction between the user and the wrist guard area can be increased, which helps the part of the user in contact with the wrist guard area to be more stably anchored in the wrist guard area. This improves the stability of the user's operation while supporting the part of the user in contact with the wrist guard area.

[0141] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 is a one-piece molded structure; or, the writing board 110 includes a horizontal wrist guard 111 and a side wrist guard 112 located in the wrist guard area, the portion of the writing board 110 located in the writing area, the horizontal wrist guard 111 and the side wrist guard 112 together form an upwardly facing first streamlined curved surface M1, and at least two of the portion of the writing board 110 located in the writing area, the horizontal wrist guard 111 and the side wrist guard 112 are one-piece molded structures; or, the writing board 110 includes a horizontal wrist guard 111 located in the wrist guard area, the portion of the writing board 110 located in the writing area and the horizontal wrist guard 111 together form an upwardly facing first streamlined curved surface M1, and the portion of the writing board 110 located in the writing area and the horizontal wrist guard 111 are one-piece molded structures.

[0142] For example, the side wrist guard 112 and the lateral wrist guard 111 can be a one-piece molded structure, and the one-piece side wrist guard 112 and the lateral wrist guard 111 can be detachably connected to the part of the writing board 110 located in the writing area.

[0143] For example, one of the horizontal wrist guard 111 and the side wrist guard 112 is integrally formed with the writing area portion of the writing board 110, while the other is detachably connected to the writing area portion of the writing board 110. For instance, the horizontal wrist guard 111 and the writing area portion of the writing board 110 are integrally formed, while the side wrist guard 112 and the writing area portion of the writing board 110 and / or the horizontal wrist guard 111 can be detachably connected via magnetic attraction, threads, snap-fit, or other methods. As another example, the side wrist guard 112 and the writing area portion of the writing board 110 are integrally formed, while the horizontal wrist guard 111 and the writing area portion of the writing board 110 and / or the side wrist guard 112 can be detachably connected via threads, magnetic attraction, slide rail, or other methods.

[0144] For example, the writing area of ​​the writing board 110, the horizontal wrist guard 111, and the side wrist guard 112 are integrally formed.

[0145] It can be understood that the writing area is a functional area contained within the writing board 110 itself. "The part of the writing board 110 located in the writing area" means the physical part of the writing board itself that is within the writing area. This part belongs to the writing board and is also within the writing area.

[0146] Thus, by configuring the writing board 110 as a one-piece structure, or configuring at least two of the three components of the writing board 110 located in the writing area, the horizontal wrist guard 111, and the side wrist guard 112 as a one-piece structure, the writing board 110 not only has a certain structural strength, but also makes it easier to maintain the integrity of the overall structure of the writing board 110, thereby improving the product's service life and maintenance convenience.

[0147] According to some embodiments of this application, at least two of the three components—the writing pad 110 located in the writing area, the lateral wrist guard 111, and the side wrist guard 112—are detachably connected.

[0148] Detachable connection methods include threaded, magnetic, and slide rail 1121, among others, and are not specifically limited here.

[0149] For example, please continue to refer to Figure 1 , Figure 2 and Figure 4 and in conjunction with reference Figure 5 , Figure 5 The diagram shows a partial structural diagram of the side wrist guard 112 in some embodiments of this application. A detachable side wrist guard 112 is provided on each side of the writing area. Each side wrist guard 112 is provided with a slide rail 1121 and a sliding groove (not shown) is provided on the side of the writing area. The side wrist guard 112 and the writing board 110 located in the writing area are detachably connected through the matching sliding groove and slide rail 1121.

[0150] Thus, at least two of the three components—the writing pad 110 located in the writing area, the horizontal wrist guard 111, and the lateral wrist guard 112—are detachably connected, which is both easy to manufacture and maintainable.

[0151] It should be noted that when the writing board 110 includes a horizontal wrist rest 111, the portion of the writing board 110 located in the writing area and the horizontal wrist rest 111 can be integrally formed or detachably connected. When the writing board 110 includes a side wrist rest 112, the portion of the writing board 110 located in the writing area and the side wrist rest 112 can be integrally formed or detachably connected. For an understanding of integral forming and detachable connection, related implementation methods, and the advantages they bring, please refer to the content illustrated in some of the foregoing embodiments, and will not be repeated here.

[0152] It should also be noted that the above embodiments illustrate various structural implementations of the writing board 110. When the writing board 110 includes a horizontal wrist guard 111 and a side wrist guard 112, there are no specific restrictions on the structural form and implementation of the horizontal wrist guard 111 and the side wrist guard 112, as long as they can achieve the required wrist protection function.

[0153] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The posture corrector 100 of the streamlined writing board also includes a support structure 130.

[0154] The support structure 130 is primarily used to support the writing board 110. For example, when the support structure 130 is placed on the placement structure, the writing surface W can be arranged at an angle.

[0155] The support structure 130 includes a support side plate 132 and a support base plate 131, which are fixedly connected to the writing board 110. The support side plate 132 is set at an acute angle to the horizontal plane; and / or

[0156] The support structure 130 has a hollow structure Q, or the support structure 130 and the writing board 110 together define the hollow structure Q; and / or

[0157] The lower end face of the support structure 130 is used to support the placement structure, and the contact method between the lower end face of the support structure 130 and the placement structure includes surface contact; and / or

[0158] The lower end face of the supporting structure is used to support the placement structure, which is a tabletop.

[0159] The supporting base plate 131 and the supporting side plate 132 refer to components with a certain length. The end of the supporting side plate 132 connected to the supporting base plate 131 may or may not contact the tabletop; no specific restrictions are imposed here.

[0160] A hollow structure Q refers to a spatial structure such as holes or pores formed by removing a portion of material from a solid material. Of course, a hollow structure Q can also be a structure defined by connecting multiple components. When the hollow structure Q is provided on the support structure 130, it can be formed by removing a portion of the material from the support structure 130, or it can be formed by connecting multiple components to the support structure 130. When the support structure 130 and the writing board 110 jointly define the hollow structure Q, it can be considered as a structure defined by connecting multiple components. Of course, when the support structure 130 and the writing board 110 are integrally formed, the hollow structure Q can be considered as being formed by removing a portion of the material from the solid material as mentioned above. No specific limitations are made here.

[0161] Thus, by setting the supporting base plate 131 and supporting side plates 132, the stability of the overall structure can be improved. When the hollow structure Q is formed, the supporting base plate 131, supporting side plates 132, and writing board 110 can roughly form a triangular support structure 130, which not only improves structural stability but also facilitates manufacturing. It should be noted that the triangular support structure 130 refers to a mechanical structure that uses three fulcrums or three supporting sides to roughly form a triangle or triangular solid, utilizing the stability of a triangle to achieve stable support. By setting the supporting side plates 132 at an acute angle to the horizontal plane, the stability of the overall structure is improved, thereby reducing the possibility of swaying or deformation during use.

[0162] By setting a hollow structure Q, not only can lightweight design be achieved and portability improved, but the center of the overall structure can also be adjusted by controlling the position of the hollow structure Q, thereby improving the stability of the overall structure.

[0163] By setting a support structure 130 to support the writing board 110, and making the contact between the support structure 130 and the placement structure include surface contact, it is not only beneficial to tilt the writing surface W of the writing board 110, but also beneficial to improve the mechanical stability of the overall structure.

[0164] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The area between the supporting side plate 132, the writing board 110, and the supporting base plate 131 is a hollow area. The hollow area can be understood with reference to the hollow structure Q shown above. The corresponding implementation method and the advantages it brings will not be repeated here.

[0165] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 includes a snap-fit ​​part 114 and a horizontal wrist guard plate 111 disposed in the wrist guard area, wherein the snap-fit ​​part 114 is connected to the horizontal wrist guard plate 111;

[0166] The snap-fit ​​portion 114 is adapted to mate with the placement structure to limit the position of the writing board 110; or

[0167] The snap-fit ​​part 114 is adapted to mate with a placement structure, wherein the placement structure is a tabletop; or

[0168] The snap-fit ​​part 114 is adapted to be connected to the tabletop.

[0169] Conventional writing boards rest directly on the surface of a table, with a friction pad underneath to secure the board and facilitate writing or reading. However, due to user posture and writing habits, there is a risk that users may move the writing board to a more comfortable position, affecting the posture correction function of the streamlined writing board's posture corrector. Therefore, this embodiment of the application incorporates a latching part 114 adapted to cooperate with the placement structure, connecting the writing board 110 to the placement structure, thereby positioning the streamlined writing board's posture corrector 100 to facilitate posture correction for the user.

[0170] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The snap-fit ​​part 114 is adapted to snap-fit ​​and fix to, for example, a tabletop, so as to fix the writing board 110 on top of the tabletop. It should be noted that the snap-fit ​​part 114 can be fixed to the tabletop by providing a telescopic snap-fit ​​rod, and can be fixedly connected to the tabletop as the thickness of the tabletop changes.

[0171] This will help improve the adaptability of the streamlined writing board's posture corrector 100 and meet the needs of different users.

[0172] It should be noted that when the aforementioned snap-fit ​​portion 114 is provided, the snap-fit ​​portion 114 and the protruding end 113 can be connected, and the snap-fit ​​portion 114 and the protruding end 113 form a third streamlined curved surface M3 on the side opposite to the transverse wrist guard plate 111. Further details will not be provided here.

[0173] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 has a slot X and a positioning groove D on the side opposite to the protruding end 113, and the positioning groove D and the slot X form an installation area.

[0174] The installation area can be used to install and / or place relevant functional components or user items, without specific limitations. Relevant functional components can be the reading board 140 shown below, without specific limitations.

[0175] In this way, by forming an installation area, it is convenient for users to use and for the expansion of functions, thereby improving the usability of the streamlined writing board posture corrector 100.

[0176] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The surface area of ​​the mounting area is 5%-25% of the surface area of ​​the writing board 110; and / or, the posture corrector 100 of the streamlined writing board also includes a reading board 140, which is connected to the writing board 110 through the mounting area; and / or, the posture corrector 100 of the streamlined writing board also includes a reading board 140 connected to the writing board 110, and the surface area of ​​the reading board 140 is 50%-80% of the surface area of ​​the writing board 110.

[0177] For example, the writing board 110 has two slots X and a positioning groove D on the side opposite to the protruding end 113, and the positioning groove D and the slots X form the mounting area of ​​the reading board 140.

[0178] For example, the surface area of ​​the mounting area can be 5%, 7%, 9%, 11%, 14%, 17%, 19%, 22%, or 25% of the surface area of ​​the writing board 110. For instance, the surface area of ​​the mounting area can preferably be 8% of the surface area of ​​the writing board 110. Of course, this value can be any value within the range of 5% to 25%, and no specific limitation is made here.

[0179] For example, within the mounting area, a slot can be used to insert a tablet computer, and a positioning recess can be used to mate with a reading board.

[0180] For example, please continue to refer to Figure 1 and Figure 2 The surface area of ​​the reading board 140 can be 50%, 52%, 55%, 60%, 62%, 70%, 75%, 78%, or 80% of the surface area of ​​the writing board 110. Of course, this value can be any value within the range of 50%-80%, and no specific restriction is made here.

[0181] In this way, by controlling the surface area of ​​the installation area, it is convenient for users to use the writing board 110 while also making the installation area easy to use.

[0182] The mounting area is formed by setting the positioning groove D and the slot X, which facilitates the installation of the reading board 140. When the reading board 140 and the writing board 110 are detachably connected, the overall height of the reading board 140 is relatively high, which may obstruct the user's line of sight when not in use, making it inconvenient for the user to observe the blackboard, etc. Therefore, making the reading board 140 and the writing board 110 detachable can improve the user's convenience.

[0183] Since items can be placed on the reading board 140, the surface area of ​​the reading board 140 is set to conform to the user's usage habits, so as to improve the situation where the reading board 140 is too large or too small, which would have an adverse effect on the writing board 110.

[0184] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The streamlined writing board posture corrector 100 also includes a reading board 140 located on the side of the writing area opposite to the wrist rest area, and a correction element 120 located on the side of the wrist rest area opposite to the writing area. The width of the reading board 140 is smaller than the width of the writing board 110. The bottom of the correction element 120, the bottom of the writing surface W, and the bottom of the reading board 140 rise successively, and the width of the reading board 140 is greater than the width of the correction element 120.

[0185] For example, when the writing surface W is tilted, the tilted writing surface W can be used to raise the bottom of the corrector 120, the bottom of the writing surface W, and the bottom of the reading plate 140 in sequence.

[0186] For example, the corrector 120 can be configured to be adjustable relative to the writing board 110. For instance, the corrector 120 is rotatably connected to the protruding end 113 and is retractable relative to the writing board 110, thus allowing the posture corrector 100 of the streamlined writing board to have different usage states. In one usage state of the posture corrector 100 of the streamlined writing board, the top of the corrector 120 is higher than the top of the writing surface W, and the top of the reading board 140 is higher than the top of the corrector 120; that is, the top of the writing surface W, the top of the corrector 120, and the top of the reading board 140 are successively raised. In another usage state of the posture corrector 100 of the streamlined writing board, the corrector 120 can be placed under the tabletop by rotation and retraction, thus retracting the corrector 120.

[0187] For example, the width of the reading board 140 is smaller than the width of the writing board 110, and the width of the reading board 140 is larger than the width of the corrector 120, so that the reading board 140 can accommodate larger books or tablets.

[0188] Thus, by controlling the positional relationships between the bottom of the corrector 120, the bottom of the writing surface W, and the bottom of the reading board 140, as well as the positional relationships between the top of the corrector 120, the top of the writing surface W, and the top of the reading board 140, a roughly "U"-shaped structure is formed, allowing the user to have a good line of sight during reading and writing. With the bottom of the corrector 120, the bottom of the writing surface W, and the bottom of the reading board 140 rising sequentially, the user has a good viewing angle during writing and reading. With the reading board 140 positioned higher than the corrector 120, it facilitates eye-level reading during use, mitigating fatigue caused by the corrector 120 being too high and requiring the user to look down. Furthermore, when the width of the writing board 110 is greater than the width of the reading board 140, and the width of the reading board 140 is greater than the width of the corrector 120, the posture corrector as a whole better meets the user's needs, improving the user experience.

[0189] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The width of the corrector 120 is smaller than the width of the writing board 110.

[0190] In this way, by controlling the width of the corrective element 120, it can be matched with the user's actual needs. While guiding the user's posture correction behavior, the corrective element 120 can also reduce the impact of distraction in scenarios such as learning, thus correcting posture scientifically. In addition, it can reduce the restriction on the user's range of motion and reduce the risk of the user bumping into the edge of the corrective element 120 when moving or placing the writing board 110.

[0191] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The corrective component 120 includes a connecting portion 121, a supporting portion 122, an elastic pad 123, and a rotating end 124. The connecting portion 121 and the supporting portion 122 are vertically arranged. The rotating end 124 is located at the bottom of the connecting portion 121, and the supporting portion 122 is located at the top of the connecting portion 121. The rotating end 124 is rotatably connected to the protruding end 113 to achieve relative rotation between the corrective component 120 and the writing board 110. Each end of the supporting portion 122 has an elastic pad 123 facing the user. The elastic pads 123 provide protection for the user's body.

[0192] For example, the support part 122 is arc-shaped, which can support the user's chin or prevent the user's shoulders from sinking, forcing the user to adjust to the correct sitting posture.

[0193] For example, the connecting part 121 is a telescopic adjustment rod, and the height of the connecting part 121 can be adjusted to accommodate users of different heights.

[0194] Thus, by configuring the corrective component 120 to include a connecting part 121, a support part 122, an elastic pad 123, and a rotating end 124, it can not only better adjust the user's sitting posture, but also protect the user's body.

[0195] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 4 and Figure 6 , Figure 6 The following is a schematic diagram of the structure of the reading board 140 in some embodiments of this application. The reading board 140 includes a reading board body 141, a clamping part 142, a mounting block 143, a book clip 144, and a mounting plate 145.

[0196] For example, the bottom of the reading board body 141 is provided with two spaced-apart mounting blocks 143, and the mounting blocks 143 are correspondingly disposed in the slot X of the writing board 110. The mounting blocks 143 are slidably inserted into the slot X. In this way, the reading board 140 can be easily inserted and inserted through the cooperation of the slot X and the mounting blocks 143, making it easy to disassemble and carry.

[0197] For example, such as Figure 1 , Figure 4 and Figure 6 As shown, the mounting block 143 is also provided with a limiting end 1431, which can slide into the support end (not shown in the figure). Through the cooperation between the support end and the limiting end 1431, the risk of the mounting block 143 disengaging from the slot X in the vertical direction is reduced, thereby improving the situation where the reading board 140 falls off accidentally.

[0198] For example, such as Figure 6 As shown, the bottom of the reading board body 141 is also provided with a mounting plate 145. The mounting plate 145 is detachably connected to the writing board 110. The mounting plate 145 is provided with two spaced-apart placement slots 1451. One end of the book clip is hinged in the placement slot 1451. The placement slots 1451 and the book clips 144 are arranged one-to-one. After the movable end of the book clip 144 is rotated, it extends out of the placement slot 1451 to cooperate with the reading board body 141 to clamp the user's book.

[0199] For example, such as Figure 6 As shown, a clamping part 142 is provided at the bottom of the reading tablet body 141. The side of the clamping part 142 is parallel to the reading tablet body 141. The clamping part 142 further supports the tablet computer, making the tablet computer more stable.

[0200] For example, such as Figure 1 , Figure 4 and Figure 6 As shown, the surface area of ​​the reading plate 140 is 50%-80% of the surface area of ​​the writing plate 110, preferably 60%. Figure 1 and Figure 4 As shown, after the reading board 140 is installed with the writing board 110, the reading board 140 is set at an angle to the plane of the table, the angle being between 60° and 85°, preferably 75°, and the end of the reading board 140 not connected to the writing board 110 is tilted away from the user.

[0201] In this way, by configuring various structures of the reading board 140, the user's comfort and convenience can be improved.

[0202] In some implementation methods, please continue to refer to Figure 1 and Figure 2 This application provides a streamlined writing board posture corrector 100, including a writing board 110. The writing board 110 is suitable for placement on a table. The writing board 110 has a writing area and a wrist rest area. The writing area has a writing surface W, which is suitable for placing items. The wrist rest area is close to the user. The writing area and the wrist rest area together form a first streamlined curved surface M1, which prevents items from falling along the writing area onto the table or the ground.

[0203] Thus, when the writing board 110 is placed at an angle on the table, the writing board 110 has a writing area and a wrist rest area. The writing area and the wrist rest area together form a first streamlined curved surface M1. When an item descends along the writing board 110, the presence of the first streamlined curved surface M1 will prevent the item from descending, giving the user a better user experience.

[0204] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The writing surface W is inclined to the horizontal plane. The wrist guard area is provided with a horizontal wrist guard plate 111. One side of the horizontal wrist guard surface H of the horizontal wrist guard plate 111 is connected to the writing surface W. The writing surface W and the horizontal wrist guard surface H form a first streamlined curved surface M1.

[0205] Thus, since the writing surface W is inclined to the horizontal plane, the writing surface W and the horizontal wrist guard surface H form a first streamlined curved surface M1, which prevents the item from sliding down.

[0206] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The cross-section of the first streamlined curved surface M1 is a curve.

[0207] Thus, the cross-section of the first streamlined curved surface M1 is curved, and the curve prevents the item from sliding down.

[0208] In some implementation methods, please continue to refer to Figure 1 and Figure 2The posture corrector 100 of the streamlined writing board also includes a support side plate 132 and a support base plate 131. The support side plate 132 and the support base plate 131 are fixedly connected to the writing board 110. The support side plate 132 is set at an acute angle to the horizontal plane. There is a hollow area between the support side plate 132, the writing board 110 and the support base plate 131.

[0209] Thus, the supporting side plate 132 and the supporting bottom plate 131 together support the writing board 110, and the hollowed-out area reduces the overall weight of the entire device.

[0210] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The wrist guard area has a protruding end 113 on the side opposite to the writing area, and the protruding end 113 has a third streamlined curved surface M3 on the side opposite to the wrist guard area.

[0211] Thus, the third streamlined curved surface M3 is positioned to place the user's arm, enhancing the user experience.

[0212] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The sides of the protruding end 113 and the wrist guard area are formed by rounded chamfers to form a third streamlined curved surface M3.

[0213] Thus, the sides of the protruding end 113 and the wrist guard area are formed by rounded chamfers to create a third streamlined curved surface M3, which facilitates support for the person's arm.

[0214] In some implementation methods, please continue to refer to Figures 1 to 3 The posture corrector 100 of the streamlined writing board also includes a correction element 120, which is rotatably connected to the protruding end 113. The width of the correction element 120 is smaller than the width of the writing board 110.

[0215] This makes the caliper 120 more suitable for users' needs.

[0216] In some implementation methods, please continue to refer to Figures 1 to 3 The protruding end 113 is provided with a receiving groove 1131, which is adapted to be rotatably connected to the rotating end 124 of the straightening member 120.

[0217] Thus, by setting the receiving groove 1131 and the rotating end 124, the rotatable connection between the corrector 120 and the writing board 110 is realized.

[0218] In some implementation methods, please continue to refer to Figure 1 and Figure 2The writing board 110 has a slot X and a positioning groove D on the side opposite to the protruding end 113. The positioning groove D and the slot X form an installation area, and the surface area of ​​the installation area is 5%-25% of the surface area of ​​the writing board 110.

[0219] Thus, the installation area is set up to facilitate the subsequent installation of the reading board 140 and the use of related components.

[0220] In some implementation methods, please continue to refer to Figure 1 , Figure 2 and Figure 6 The posture corrector 100 of the streamlined writing board also includes a reading board 140, which is connected to the writing board 110. The surface area of ​​the reading board 140 is 50%-80% of the surface area of ​​the writing board 110.

[0221] Thus, the surface area of ​​the reading board 140 is set to suit the user's usage habits. At the same time, it improves the situation where the reading board 140 is too large or too small, which would have an adverse effect on the writing board 110.

[0222] In some implementation methods, please continue to refer to Figure 1 , Figure 2 and Figure 6 The width of the reading board 140 is smaller than the width of the writing board 110, and the width of the reading board 140 is larger than the width of the corrector 120. The bottom of the corrector 120, the bottom of the writing surface W, and the bottom of the reading board 140 rise sequentially. In one usage state of the posture corrector 100 of the streamlined writing board, the top of the corrector 120 is higher than the top of the writing surface W, and the top of the reading board 140 is higher than the top of the corrector 120.

[0223] Thus, by progressively raising the bottom of the corrector 120, the bottom of the writing surface W, and the bottom of the reading board 140, and combining this with the top of the corrector 120 being higher than the top of the writing surface W and the top of the reading board 140 being higher than the top of the corrector 120, a "U"-shaped structure is formed, ensuring good visibility for the user during reading and writing. The width of the reading board 140 is greater than the width of the corrector 120, so that the reading board 140 can accommodate larger books or tablets.

[0224] In some implementation methods, please continue to refer to Figure 1 and Figure 2 A lateral wrist guard 112 is provided on each side of the writing board 110. The lateral wrist guard 112 is connected to the writing board 110, and a second streamlined curved surface M2 is formed between the lateral wrist guard 112 and the writing board 110.

[0225] Thus, by providing a lateral wrist rest 112, the user's elbow or wrist can be supported, improving the situation of the wrist being suspended in the air. The second streamlined curved surface M2 further mitigates the risk of injury to the user's elbow or wrist from straight lines. It should be noted that the lateral wrist rest 112 is connected to the writing board 110, meaning that the lateral wrist rest 112 is part of the writing board 110, and the lateral wrist rest 112 is connected to the other parts of the writing board 110.

[0226] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The side of the lateral wrist guard 112 has a lateral curved surface, and the straight line of the side of the writing board 110 and the lateral curved surface of the lateral wrist guard 112 form a second streamlined curved surface M2.

[0227] Thus, improving the straight line can prevent injury to the user's wrist or elbow. It should be noted that "straight line" refers to a shape of the side, and "straight line on the side" means that this part of the side extends in a straight line.

[0228] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The surface area of ​​the lateral wrist guard 112 is 3%-15% of the surface area of ​​the writing board 110.

[0229] Therefore, the side wrist guard 112 does not need to be too large, which can reduce the company's production costs.

[0230] In some implementation methods, please continue to refer to Figure 1 and Figure 2 The horizontal wrist guard 111 is connected to the snap-fit ​​part 114 of the writing board 110, and the snap-fit ​​part 114 is adapted to be connected to the table.

[0231] Thus, the writing board is connected to the tabletop via the snap-fit ​​part 114.

[0232] It should be noted that some other advantages and implementation methods in the above-described embodiments can be understood by referring to the situations illustrated in the foregoing embodiments, and will not be repeated here.

[0233] The following description, in conjunction with the embodiments illustrated in the above examples, provides an exemplary description of the posture corrector for the streamlined writing board provided in this application, but it is not intended to be limited thereto.

[0234] Example 1

[0235] like Figure 1-3 A specific embodiment of the posture corrector 100 of the streamlined writing board shown in Figures 5 and 6 includes: a writing board 110, and a correction element 120 and a reading board 140 respectively connected to the writing board 110.

[0236] like Figure 1 and Figure 2 As shown, the writing board 110 has a writing area and a wrist rest area, with the wrist rest area facing the user. The writing area and the wrist rest area together form a first streamlined curved surface M1, that is, the writing surface W of the writing area is inclined to the horizontal plane. The wrist rest area has a horizontal wrist rest plate 111, one side of the horizontal wrist rest surface H of the horizontal wrist rest plate 111 is smoothly connected to the writing surface W. The writing surface W and the horizontal wrist rest surface H form the first streamlined curved surface M1. The cross-section of the first streamlined curved surface M1 is curved, and the first streamlined curved surface M1 prevents items from falling along the writing area onto the table or the ground.

[0237] In this embodiment, the horizontal wrist rest surface H refers to the entire upper surface of the horizontal wrist rest plate 111, and the writing surface W refers to the upper surface of the writing area of ​​the writing board 110. It should be noted that the first streamlined curved surface M1 is concave. The writing board 110 has a writing surface W that is angled to the horizontal plane, and the writing surface W is suitable for placing items. In this embodiment, the items are books, tablet computers, etc.

[0238] The writing board 110 has a protruding end 113 on the side facing the user, wherein the protruding end 113 has a receiving groove 1131, which is adapted to be rotatably connected to the rotating end 124 of the corrector 120. The side of the protruding end 113 away from the writing area has a third streamlined curved surface M3. The setting of the third streamlined curved surface M3 can reduce the risk of injury to the user and can limit the protruding end 113 from the user.

[0239] like Figure 2 As shown, the writing board 110 also has a snap-fit ​​part 114, which is connected to the protruding end 113. The snap-fit ​​part 114 is adapted to snap-fit ​​and fix to the tabletop to fix the writing board 110 above the tabletop. It should be noted that the snap-fit ​​part 114 is fixed to the tabletop by setting a telescopic snap-fit ​​rod, and is fixedly connected to the tabletop as the thickness of the tabletop changes.

[0240] like Figure 2 As shown, the writing tablet 110 has two slots X and a positioning groove D on the side opposite to the protruding end 113. The positioning groove D and the slots X form the mounting area of ​​the reading tablet 140. The surface area of ​​the mounting area is 5%-25% of the surface area of ​​the writing tablet 110, preferably 8%. It should be noted that within the mounting area, the slots X are used to insert a tablet computer, and the positioning groove D is used to mate with the reading tablet. Figure 1 , Figure 2As shown, the protruding end 113 has a third streamlined curved surface M3 on the side opposite to the writing area. That is, a third streamlined curved surface M3 is formed between the protruding end 113 and the latching part 114. Specifically, the sides of the protruding end 113 and the wrist support area are formed with rounded chamfers to create the third streamlined curved surface M3. The third streamlined curved surface M3 is formed to accommodate and support the user's arm.

[0241] like Figure 1 As shown, the posture corrector 100 of the streamlined writing board also includes a supporting side plate 132 and a supporting base plate 131. The supporting side plate 132 and the supporting base plate 131 are fixedly connected to the writing board 110. The supporting base plate 131 is the plate that contacts the plane of the tabletop, and the supporting side plate 132 is the plate that is set at an acute angle to the plane of the tabletop. The area between the supporting side plate 132, the writing board 110, and the supporting base plate 131 is a hollow area, which forms a hollow structure Q.

[0242] like Figure 1 , Figure 2 and Figure 5 As shown, the writing pad 110 also has a detachable side wrist rest 112 on each side. Each side wrist rest 112 has a slide rail 1121, and the side of the writing pad 110 has a sliding groove. The detachable connection is achieved through the matching sliding groove and slide rail 1121. It should be noted that the surface area of ​​the side wrist rest 112 is 3%-15% of the surface area of ​​the writing pad 110, preferably 5%. The side wrist rest 112 mainly supports the user's elbow and / or wrist and does not need to be too large. Figure 1 , Figure 2 As shown, a second streamlined curved surface M2 is formed between the lateral wrist rest 112 and the writing board 110. Specifically, the side of the lateral wrist rest 112 has a lateral curved surface, and the straight line of the side of the writing board 110 and the lateral curved surface of the lateral wrist rest 112 form the second streamlined curved surface M2. By forming the second streamlined curved surface M2, the risk of injury to the user's elbow or wrist from straight lines can be reduced. For easier lateral support, the writing board also includes a lateral wrist rest 111. The lateral wrist rest 111 is detachably connected to the writing board 110 via a locking block and a locking slot. It should be noted that the lateral wrist rest 111 is located above the locking portion 114. It should also be noted that both the lateral wrist rest 112 and the lateral wrist rest 111 are equipped with anti-slip strips F1.

[0243] It should be noted that the first streamlined curved surface M1 can be understood based on the structure of the writing board 110. For example, when a horizontal wrist guard 111 is provided, the horizontal wrist guard surface H of the horizontal wrist guard 111 constitutes a portion of the first streamlined curved surface M1. For example, when a lateral wrist guard 112 is provided, the lateral wrist guard surface C of the lateral wrist guard 112 constitutes a portion of the first streamlined curved surface M1. For example, when both the horizontal wrist guard 111 and the lateral wrist guard 112 are provided, the writing surface W, the horizontal wrist guard surface H, and the lateral wrist guard surface C together form the first streamlined curved surface M1. This can be understood in conjunction with the situations illustrated in some of the foregoing embodiments, and will not be elaborated upon here.

[0244] like Figures 1 to 3 As shown, the orthodontic component 120 includes a connecting portion 121 and a supporting portion 122, wherein the connecting portion 121 and the supporting portion 122 are arranged vertically. The bottom of the connecting portion 121 has a rotating end 124, and the top of the connecting portion 121 has the supporting portion 122. The rotating end 124 is rotatably connected to the protruding end 113 of the writing board 110 to achieve relative rotation between the orthodontic component 120 and the writing board 110. It should be noted that the supporting portion 122 is arc-shaped to support the user's chin or prevent the user's shoulders from sagging, forcing the user to adjust to a correct sitting posture. It should also be noted that the connecting portion 121 is a telescopic adjustment rod, allowing adjustment of its height to accommodate users of different heights. Figure 3 As shown, each end of the support 122 is provided with an elastic pad 123 facing the user, so as to protect the user's body.

[0245] like Figure 6 As shown, the bottom of the reading board 140 has two spaced-apart mounting blocks 143, which correspond to the slot X of the writing board 110. The mounting blocks 143 are slidably inserted into the slot X. Thus, the reading board 140 can be easily inserted and removed through the cooperation of the slot X and the mounting blocks 143, facilitating its disassembly and transport. Figure 6 As shown, the mounting block 143 also has a limiting end 1431, which can slide into the support end. Through the cooperation between the support end and the limiting end 1431, the mounting block 143 is prevented from vertically disengaging from the slot X, thereby preventing the reading plate 140 from accidentally falling off. Figure 6 As shown, the bottom of the reading board 140 is also provided with a mounting plate 145, which is detachably connected to the writing board 110. The mounting plate 145 has two spaced-apart placement slots 1451. One end of a book clip 144 is hinged into the placement slot 1451. The placement slots 1451 and book clips 144 are arranged in a one-to-one correspondence. The movable end of the book clip 144 extends out of the placement slot 1451 after rotation to cooperate with the reading board 140 and clamp the user's book. Figure 6As shown, the bottom of the reading tablet 140 is provided with a clamping part 142. The side of the clamping part 142 is parallel to the reading tablet 140. The clamping part 142 further supports the tablet computer, making the tablet computer more stable. Figure 1 , Figure 2 and Figure 6 As shown, the surface area of ​​the reading plate 140 is 50%-80% of the surface area of ​​the writing plate 110, preferably 60%. Figure 1 As shown, after the reading board 140 is installed with the writing board 110, the reading board 140 is set at an angle to the plane of the table, the angle being between 60° and 85°, preferably 75°, and the end of the reading board 140 not connected to the writing board 110 is tilted away from the user.

[0246] The adjustable wrist rest posture corrector provided in this application features a series of progressively higher bottom sections: the bottom of the corrector 120, the bottom of the writing surface W, and the bottom of the reading board 140. This ensures a good viewing angle for the user during writing and reading. Furthermore, in one usage state of the posture corrector 100 on the streamlined writing board, the reading board 140 is positioned higher than the corrector 120, facilitating eye-level reading. This increased viewing distance prevents eye strain caused by the corrector 120 being too high, thus preventing myopia. Additionally, the width of the writing board 110 is greater than the width of the reading board 140, and the width of the reading board 140 is greater than the width of the corrector 120, making the overall posture corrector more user-friendly and enhancing the user experience.

[0247] As an alternative implementation, the side wrist rest 112 and the writing board 110 can also be detachably connected by other means such as magnetic attraction, thread, or snap-fit. That is, depending on the structure of the writing board 110, the side wrist rest 112 and the structure in the writing board 110 can be detachably connected.

[0248] As an alternative implementation, the horizontal wrist rest 111 and the writing board 110 can also be detachably connected by other means such as threads, magnets, or slide rails. That is, depending on the structure of the writing board 110, the horizontal wrist rest 111 and the structure within the writing board 110 can be detachably connected.

[0249] As an alternative implementation, the side wrist guard 112 and the lateral wrist guard 111 can also be integrated as a single unit, and the integrated side wrist guard 112 and lateral wrist guard 111 can be detachably connected to the structure in the writing board 110.

[0250] As an alternative implementation, the first streamlined surface M1 can be a curve of other shapes, such as a convex surface.

[0251] As an alternative implementation, the number of mounting blocks 143 can also be 3, 4, or even more.

[0252] Example 2

[0253] In this embodiment, as Figure 4 As shown, the writing board 110, the side wrist rest 112, and the horizontal wrist rest 111 are integrally formed. That is, based on the structure of the writing board 110, the side wrist rest 112, the horizontal wrist rest 111, and the structure within the writing board 110 are all integrally formed. The anti-slip strip F1 of the side wrist rest 112 is removed, and an anti-slip material is applied to the corresponding position of the side wrist rest 112 to form an anti-slip layer F2. The other structures in this embodiment are the same as in Embodiment 1.

[0254] It is understood that the embodiments 1 and 2 shown above do not fully illustrate all the various implementation methods shown in the foregoing embodiments. The various ways of forming streamlined curved surfaces and other structural implementation methods shown in the foregoing embodiments can be freely combined and implemented, and no specific limitations are made here. In addition, the structure in the writing board 110 can be understood as the part of the writing board 110 shown in the foregoing embodiments located in the writing area.

[0255] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
