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 lower 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 objects 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 posture corrector in the related technology. In the design and manufacturing process, the entire writing board is designed as a straight board and the writing board is tilted 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 under the action of gravity, which has the defect of poor user experience.

[0063] 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.

[0066] 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.

[0067] 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 a streamlined writing tablet posture corrector 100 with some structures removed, as shown in some embodiments of this application. This application provides a streamlined writing tablet posture corrector 100, which includes a writing tablet 110 and a support structure 120. The writing tablet 110 includes a writing area and a wrist rest area, with the wrist rest area positioned close to the user. The writing area and the wrist rest area together form an upward-facing first streamlined curved surface M1. The support structure 120 is located on the lower end face of the writing tablet 110. The support structure 120 is used to support the writing tablet on a placement structure, allowing the upper surface of the writing area to be inclined.

[0068] 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 upper surface facing the user. The upper surfaces of the writing area and the wrist rest area can also be considered as user-facing surfaces, meaning the surfaces that the user directly contacts during use with their body or operating behavior. In other words, the user-facing surface is not necessarily the surface directly facing the user.

[0069] 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 (e.g., 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.

[0070] The support structure 120 is mainly used to support the writing board 110. When the support structure 120 is placed on the placement structure, the upper surface of the writing area can be arranged at an angle. For example, the placement structure can be a tabletop.

[0071] For example, in conjunction with reference Figure 1 and Figure 2 The upper surface of the writing area is tilted, which can be seen as an upward extension of the upper surface of the writing area away from the wrist guard area.

[0072] When the upper surface of the writing area of ​​the writing board 110 is placed at an angle on the table, as an object falls along the writing area, the formation of the first streamlined curved surface M1 structure not only increases the contact area to enhance 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 helping to reduce the risk of the object falling onto the table or the ground along the writing area.

[0073] Therefore, this embodiment of the application provides a support structure 120 to support the writing board 110, causing the upper surface of the writing board 110 to be tilted. For the user, this increases the viewing distance, reducing the probability of eye fatigue during study and facilitating proper posture correction. By configuring the writing board 110 to include a writing area and a wrist rest area positioned close to the user, the writing area and wrist rest area together form an upward-facing first streamlined curved surface M1. When an object descends along the writing board 110, the presence of the first streamlined curved surface M1 prevents the object from falling, providing a better user experience. The first streamlined curved surface M1 helps match the user's posture, improving user comfort, assisting in maintaining proper posture, correcting poor sitting posture, and effectively preventing myopia.

[0074] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2The 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 first reference surface. The intersection of the first reference surface and the first streamlined surface M1 is a curve.

[0075] For example, the curve can be a smooth curve. A smooth curve is one without sharp inflection points and without abrupt changes in the direction of the tangent.

[0076] Because the intersection of the first streamlined surface M1 and the first reference surface is a curve, the first streamlined surface M1 extends in a curved path from the side away from the user to the side facing the user. This allows the first streamlined surface M1 to be roughly considered as a curve swept along a direction perpendicular to the first reference surface. Consequently, when an item falls along the writing area, regardless of where it falls within the writing area, it helps to prevent the item from falling. Furthermore, it also helps to further improve the user's comfort and ease of use when in contact with the first streamlined surface M1. If the intersection line is a smooth curve, it further helps to improve user comfort and ease of use while preventing the item from falling.

[0077] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The surface facing upwards in the wrist guard area is curved. That is, the portion of the first streamlined curved surface M1 corresponding to the wrist guard area is curved, and this curved surface constitutes part of the first streamlined curved surface M1.

[0078] Since the wrist rest area is the area on the writing board 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.

[0079] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The first streamlined curved surface M1 includes a smooth transition surface, which is formed at a preset location on the writing board 110. The preset location includes at least one of the following: the junction between the wrist guard area and the writing area, and the wrist guard area itself.

[0080] A smooth transition surface is a surface without sharp inflection points and without abrupt changes in tangent direction. A smooth transition surface can include various types of surfaces, and no specific limitations are made here.

[0081] The preset area refers to the area with a smooth transition surface. The preset area can be the junction between the wrist support area and the writing area, or it can be the wrist support area itself, or the junction between the wrist support area and the writing area and the wrist support area; no specific limitation is made here. Taking the junction between the wrist support area and the writing area as an example, the junction between the wrist support area and the writing area forms a smooth transition surface, meaning that the wrist support area and the writing area are seamlessly connected. As mentioned above, because a smooth transition surface is formed, it means that there are no sharp inflection points or abrupt changes in the tangential direction from the writing area to the wrist support area, or vice versa, achieving a smooth connection between the writing area and the wrist support area.

[0082] By creating a smooth transition surface at the junction of the wrist rest area and the writing area, the user's wrist and / or elbow can be supported in the wrist rest area while the user's hand (e.g., fingers and / or palm) moves in the writing area during writing or drawing. The positions of both will switch more naturally with the range of operation (e.g., from left to right, from top to bottom), allowing for smooth and natural movement of the relevant parts of the user, reducing resistance and improving comfort. It's understandable that if the junction between the wrist rest area and the writing area were a flat surface, it would either create a sharp angle or be a tilted plane, failing to provide adequate support for the user's wrist or hand, or resulting in incorrect force application. Therefore, compared to a flat surface junction that makes the writing board 110's upward-facing surface tilted, a smooth transition surface at the junction of the wrist rest area and the writing area is more conducive to improving the user's posture and comfort.

[0083] By setting a smooth transition surface in the wrist support area, the smooth transition surface of the wrist support area is more conducive to conforming to the physiological curve of the user's wrist and / or elbow. While increasing the contact area, it allows the weight of the user's wrist and / or elbow to be more evenly distributed in the wrist support area, reducing muscle fatigue and thus improving the comfort of use.

[0084] 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 curved surface M1, is the first reference surface. The intersection of the first reference surface and the smooth transition surface is a smooth curve.

[0085] A smooth curve is a line without sharp inflection points and without abrupt changes in the direction of its tangent.

[0086] Because the intersection of the first reference surface and the smooth transition surface is a smooth curve, the smooth transition surface extends smoothly from the side away from the user to the side facing the user. This allows the smooth transition surface to be roughly viewed as a smooth curve swept along a direction perpendicular to the first reference surface. This further enhances user comfort and coordination when in contact with the smooth transition surface, 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.

[0087] According to some embodiments of this application, the first streamlined curved surface M1 is concave; or, the first streamlined curved surface M1 is convex.

[0088] 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.

[0089] 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.

[0090] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 is located on the upper surface of the writing area, which at least forms a writing surface W. The writing surface W is suitable for placing items. The writing surface W is inclined to the horizontal plane. The writing surface W forms 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.

[0091] That is, the upper surface of the writing board 110, as mentioned above, at least constitutes the writing surface W. The horizontal plane can be understood as the placement plane of the placement structure. The placement plane of the placement structure can be the tabletop of the table. The writing surface W is inclined relative to the horizontal plane, that is, when the posture corrector 100 of the streamlined writing board is placed on the placement plane of the placement structure, the writing surface W is inclined. For example, when the support structure 120 is placed on the placement structure, the writing surface W is inclined.

[0092] 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.

[0093] 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.

[0094] 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 112 located in the wrist guard area, and the upward-facing surface of the horizontal wrist guard 112 constitutes part of the first streamlined curved surface M1.

[0095] The term "horizontal" in "horizontal wrist rest 112" refers to the spatial position of the wrist rest 112, while "wrist rest" represents its primary functional attribute. The horizontal direction of the wrist rest 112 refers to the direction that matches the user's operating posture. For example, when a user is writing in a normal seated position, their body is directly facing the writing surface W, and their arm is naturally placed on the edge of the writing pad 110. In this case, the horizontal direction is roughly parallel to the direction in which the user's forearm or wrist is positioned. For instance, if the writing pad 110 is tilted forward or backward, the horizontal direction can be horizontal.

[0096] The upward-facing surface of the horizontal wrist rest 112 is the horizontal wrist rest surface H. The horizontal wrist rest surface H is the surface on the horizontal wrist rest 112 that primarily supports the user's wrist and / or elbow. The horizontal wrist rest surface H and the aforementioned writing surface W constitute at least a part of the first streamlined curved surface M1, that is, one side of the horizontal wrist rest surface H smoothly connects with the writing surface W.

[0097] Thus, by setting the horizontal wrist guard 112, it is easier to match the user's operating posture, thereby further improving the wrist guard's performance and enhancing the user's comfort.

[0098] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing pad 110 includes a writing section 111 located in the writing area, and lateral wrist rests 113 located on both sides of the writing section 111 along a first direction. The upward-facing surfaces of the lateral wrist rests 113 form part of a first streamlined curved surface M1. The first direction intersects with the direction from the side of the writing area away from the user to the side of the writing area towards the user.

[0099] The term "lateral" in lateral wrist guard 113 refers to the spatial orientation of lateral wrist guard 113. Unlike the lateral extension of transverse wrist guard 112, lateral wrist guard 113 is located on both sides of writing section 111 along a first direction. The first direction can be roughly considered as the lateral extension direction of transverse wrist guard 112. When the transverse direction is horizontal, lateral wrist guard 113 is located on the left and right sides of writing section 111, forming an enclosure or extension of the left and right sides of writing section 111.

[0100] The "wrist support" in the lateral wrist brace 113 reflects its main functional attribute. In combination with the spatial posture of the lateral wrist brace 113, the lateral wrist brace 113 mainly provides support for the side of the user's wrist and the edge of the forearm.

[0101] The upward-facing surface of the side wrist rest 113 is called the side wrist rest surface C. The side wrist rest surface C is the surface on the side wrist rest 113 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.

[0102] Thus, by setting the side wrist guard 113, the writing board 110 can provide edge support for the user on both sides, thereby providing the user with a wider range of use. This is beneficial for providing more support for the user's wrist and / or elbow, and can further help to adapt to the natural trajectory of the wrist's left and right movement, reduce lateral fatigue, and further improve the comfort and stability during writing, drawing and other operations.

[0103] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The lateral wrist guard 113 is located away from the side surface of the writing part 111, and together with the side surface of the writing part 111 on which the lateral wrist guard 113 is located, they form a second streamlined curved surface M2.

[0104] by Figure 1 and Figure 2For example, the writing unit 111 has a side with a lateral wrist guard 113, including a portion connected to the lateral wrist guard 113, and another portion other than the portion connected to the lateral wrist guard 113. This other portion forms a second streamlined curved surface M2 with the side surface of the lateral wrist guard 113 opposite to the writing unit 111.

[0105] For example, the side of the lateral wrist rest 113 may have a lateral curved surface, and the side of the writing part 111 may have a straight surface. The straight surface of the writing part 111 and the lateral curved surface of the lateral wrist rest 113 may form a second streamlined curved surface M2. Of course, the side of the writing part 111 may also have a lateral curved surface, and there is no specific limitation here.

[0106] Compared to forming a straight surface, forming a second streamlined curved surface M2 can eliminate structures such as sharp edges and corners that cause a gritty feel. This transforms the hard contact process into a soft transition process when the user touches the edge when moving their body or placing objects, reducing the risk of scratches and abrasions caused by bumps and collisions and improving safety.

[0107] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The writing board 110 also includes a writing section 111 located in the writing area and a horizontal wrist guard 112 located in the wrist guard area. The writing section 111, the horizontal wrist guard 112 and the side wrist guard 113 together form an upward-facing first streamlined curved surface M1.

[0108] The writing section 111, the horizontal wrist rest 112, and the lateral wrist rest 113 together form an upward-facing streamlined curved surface M1. This means that both the horizontal wrist rest surface H and the lateral wrist rest surface C smoothly connect to the writing surface W, ensuring support for the user's wrist and / or elbow in both horizontal and lateral directions. It is understood that when a user performs operations such as writing or drawing, the movement of the arm and wrist is multi-directional and complex. By providing support for the user's wrist and / or elbow in both horizontal and lateral directions with the first streamlined curved surface M1, the user's extra effort is reduced, fatigue is decreased, and user comfort is further improved.

[0109] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The upward-facing surface of the lateral wrist guard 113 and the upward-facing surface of the transverse wrist guard 112 together form a sub-streamlined surface, which constitutes a part of the first streamlined surface M1. That is, the transverse wrist guard surface H and the lateral wrist guard surface C together form the sub-streamlined surface.

[0110] The sub-streamlined surface is a localized streamlined structure formed by two contact surfaces: the lateral wrist guard surface H and the side wrist guard surface C. The lateral wrist guard surface H and the side wrist guard surface C do not exist independently; rather, through a streamlined design, they form a continuous surface covering both the lateral and sideways directions. The part of the user in contact with the sub-streamlined surface can move from the lateral direction to the side, or vice versa.

[0111] Thus, by forming a sub-streamlined curved surface through the horizontal wrist guard 112 and the side wrist guard 113, the synergistic effect between the horizontal wrist guard 112 and the side wrist guard 113 further enhances the user's comfort during continuous operation.

[0112] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The side wrist guard 113 is located away from the writing part 111 on one side surface, and together with the side of the transverse wrist guard 112 located near the side wrist guard 113, it forms a third streamlined curved surface M3.

[0113] The third streamlined surface M3 is a streamlined structure of the edge region formed by the side surface of the lateral wrist guard 113 and the side surface of the transverse wrist guard 112. In other words, the outer contour of the writing board 110 is streamlined and optimized by the third streamlined surface M3.

[0114] By forming the aforementioned third streamlined curved surface M3 at the edge of the wrist guard area of ​​the writing board 110, structures such as sharp edges and corners that cause abrasion can be eliminated. This transforms the hard contact process into a soft transition process when the user touches the edge area while moving their body or placing objects, thereby reducing the risk of scratches and abrasions caused by bumps and collisions and improving safety during use.

[0115] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The horizontal wrist guard 112 includes a main body 1121 connected to the writing section 111, and protrusions 1122 provided at both ends of the main body 1121 along the horizontal direction of the horizontal wrist guard 112. The protrusions 1122 protrude from the writing section 111 and are connected to the side wrist guard 113.

[0116] The main body 1121 is the primary functional area of ​​the transverse wrist rest 112, directly connected to the writing section 111. It is the main part supporting the user's wrist and / or elbow, providing basic wrist support. The protrusions 1122 are arranged transversely along the left and right ends of the main body 1121, extending from the main body 1121 to the left and right sides. The upward-facing surfaces of the main body 1121 and the protrusions 1122 constitute the upward-facing surface of the transverse wrist rest 112, also known as the transverse wrist rest surface H. Through the interaction of the main body 1121 and the protrusions 1122, the transverse wrist rest 112 and the lateral wrist rest 113 ultimately form an edge structure surrounding the writing section 111.

[0117] In this way, not only can the range of the wristband be extended to cover the blind spots of the user's wrist and / or elbow movements, but it can also provide a structural basis for the continuity of the wristband, thereby further improving the user's comfort.

[0118] It should be noted that, in conjunction with reference Figure 3 , Figure 3 This is a schematic diagram of the writing board 110 area in the posture corrector 100 of the streamlined writing board in some embodiments of this application. The main body 1121 and the protrusion 1122 of the horizontal wrist rest 112 are distinguished by dashed lines. The dashed lines are for illustrative purposes only and do not represent a limitation on the junction of the main body 1121 and the protrusion 1122. Of course, there may be a clear boundary between the main body 1121 and the protrusion 1122, or there may be no clear boundary; no specific limitation is made here. In the embodiments of this application, there is no clear boundary between the main body 1121 and the protrusion 1122.

[0119] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The protrusion 1122 and the side wrist guard 113 together form an upward-facing sub-streamlined surface, which constitutes part of the first streamlined surface M1.

[0120] Based on the illustrations in the foregoing embodiments, when the surface of the lateral wrist guard 113 facing upwards and the surface of the lateral wrist guard 112 facing upwards together form a sub-streamlined surface, since the lateral wrist guard 112 includes a main body 1121 and a protrusion 1122, the surface of the protrusion 1122 facing upwards and the surface of the lateral wrist guard 113 facing upwards can together form a sub-streamlined surface. The surface of the protrusion 1122 facing upwards constitutes the lateral edge portion of the lateral wrist guard surface H. In other words, the lateral edge portion of the lateral wrist guard surface H and the lateral wrist guard surface C form a sub-streamlined surface.

[0121] When the user moves the contact point with the writing pad 110 to the left or right, they will sequentially contact the upward-facing surface of the main body 1121 of the horizontal wrist rest 112, the upward-facing surface of the protrusion 1122, and the upward-facing surface of the side wrist rest 113. Because the sub-streamlined curved surface formed by the upward-facing surface of the protrusion 1122 and the upward-facing surface of the side wrist rest 113 reduces the feeling of obstruction and suspension when moving the side wrist rest 113 from the protrusion 1122, making the wrist rest function more seamless and the user experience more comfortable.

[0122] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 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 sub-streamlined surface, is the second reference surface. The intersection of the second reference surface and the sub-streamlined surface is a curve.

[0123] For example, the curve can be a smooth curve. A smooth curve is one without sharp inflection points and without abrupt changes in the direction of the tangent.

[0124] Because the intersection of the second reference surface and the sub-streamlined surface is a curve, the sub-streamlined surface extends in a curved path from the side away from the user to the side facing the user. This allows the sub-streamlined surface to be roughly viewed as a curve swept along a direction perpendicular to the second reference surface, thereby further improving user comfort and ease of use when in contact with the sub-streamlined surface. If the intersection is a smooth curve, user comfort and ease of use can be further enhanced.

[0125] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The protrusion 1122 is on one side of the writing part 111, and together with the side wrist guard 113 on one side of the writing board 110, they form a third streamlined curved surface M3.

[0126] Based on the illustrations in the foregoing embodiments, when the side surface of the lateral wrist guard 113 facing away from the writing section 111, together with the side surface of the lateral wrist guard 112 near the lateral wrist guard 113, forms a third streamlined curved surface M3, since the lateral wrist guard 112 includes a main body 1121 and a protrusion 1122, the protrusion 1122 can be on a side surface facing away from the writing section 111, and together with the side surface of the lateral wrist guard 113 facing away from the writing board 110, form the third streamlined curved surface M3. The side surface of the protrusion 1122 constitutes the horizontal edge portion of the lateral wrist guard surface H. In other words, the horizontal edge of the lateral wrist guard surface H and the side surface of the lateral wrist guard surface C form the third streamlined curved surface M3.

[0127] Thus, in addition to the advantages of forming the third streamlined curved surface M3 mentioned above, the overall structure, from the writing section 111 to the horizontal wrist guard 112 and then to the lateral wrist guard 113, forms a continuous surface without sharp edges, sudden protrusions, or sudden depressions. When the horizontal wrist guard 112 and the lateral wrist guard 113 work together to expand the wrist support range, user comfort can be further improved.

[0128] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The protrusion 1122 protrudes beyond the maximum length of the writing portion 111, which is greater than the maximum length of the lateral wrist guard 113 extending in a direction away from the writing portion 111.

[0129] The lengths by which each part of the protrusion 1122 protrudes beyond the writing portion 111 can be the same or different. When the lengths by which each part of the protrusion 1122 protrudes beyond the writing portion 111 are the same, the maximum length of the protrusion 1122 protruding beyond the writing portion 111 is the length of each part protruding beyond the writing portion 111. When the lengths by which each part of the protrusion 1122 protrudes beyond the writing portion 111 are different, the maximum length of the protrusion 1122 protruding beyond the writing portion 111 is the longest among the lengths of each part of the protrusion 1122 protruding beyond the writing portion 111. The maximum length of the lateral wrist guard 113 extending in the direction away from the writing portion 111 can be understood with reference to the maximum length of the protrusion 1122 protruding beyond the writing portion 111, and will not be described again.

[0130] This allows the protrusion 1122 to extend further than the side wrist guard 113, thus better accommodating the lateral movement of the user's arm and providing support for the contact area between the user and the writing pad 110.

[0131] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The protrusion 1122 has a first side that connects to the lateral wrist guard 113, and a second side that is disposed opposite to the first side. The first side is the side of the protrusion 1122 that faces the writing section 111.

[0132] In the direction from the first side to the second side, the length of the protrusion 1122 protruding from the writing portion 111 first increases and then decreases; or, in the direction from the first side to the second side, the length of the protrusion 1122 protruding from the writing portion 111 increases; or, in the direction from the first side to the second side, the length of the protrusion 1122 protruding from the writing portion 111 decreases.

[0133] "A trend of increasing" describes a situation where the overall size of the protrusion 1122 extending beyond the writing portion 111 increases. For example, this could mean a continuous increase, or an initial increase followed by a decrease. "Increase followed by decrease" means that the size of the protrusion 1122 extending beyond the writing portion 111 first experiences an increase phase, then a decrease phase, but even during the decrease phase, the size of the protrusion 1122 extending beyond the writing portion 111 still increases. In other words, during the decrease phase, the protrusion 1122 still protrudes relative to the writing portion 111. "A trend of decreasing" is the opposite of "a trend of increasing." "A trend of decreasing" describes a situation where the overall size of the protrusion 1122 extending beyond the writing portion 111 decreases. This can be understood by referring to "a trend of increasing" and following the opposite trend; further elaboration is omitted here.

[0134] The phrase "increasing first and then decreasing" describes how the size of the protrusion 1122 protruding from the writing section 111 first undergoes an increasing phase and then a decreasing phase. During the decreasing phase, the size of the protrusion 1122 protruding from the writing section 111 may continue to increase or may not increase at all. That is, during the decreasing phase, the protrusion 1122 may still protrude relative to the writing section 111, or it may retract into the writing section 111 at its end. Here, the end refers to the end of the protrusion 1122 facing the user, in the direction from the first side to the second side.

[0135] For example, with Figures 1 to 3 For example, along the direction from the first side to the second side, the length of the protrusion 1122 protruding from the writing part 111 first increases and then decreases. That is, the length of the protrusion 1122 protruding from the writing part 111 presents a shape that first protrudes and then retracts in the opposite direction to the protrusion. It can be understood that even when it retracts in the opposite direction to the protrusion, the protrusion 1122 is still set to protrude relative to the writing part 111.

[0136] Thus, based on the contact frequency, pressure magnitude, and range of motion of the arm in different areas of the protrusion 1122, the degree of protrusion of the protrusion 1122 from the writing part 111 can be controlled, so that the protrusion 1122 has a certain degree of support while also having a certain degree of comfort and flexibility.

[0137] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 Along the direction from the first side to the second side, the length of the lateral wrist guard 113 extending in the direction away from the writing portion 111 tends to increase. At the junction of the lateral wrist guard 113 and the protrusion 1122, the length of the lateral wrist guard 113 extending in the direction away from the writing portion 111 is equal to the length of the protrusion 1122 protruding from the writing portion 111.

[0138] This arrangement, with the writing pad 110 generally facing the user's side in an open manner, not only provides the user with a wider range of use and better supports the user's wrist and / or elbow, but also saves space on the side of the wrist rest 113 away from the user.

[0139] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 Along the direction in which the lateral wrist rest 113 extends toward the user, the size of the lateral wrist rest 113 protruding from the writing part 111 tends to increase; or, along the direction in which the lateral wrist rest 113 extends toward the user, the size of the lateral wrist rest 113 protruding from the writing part 111 tends to first increase and then decrease.

[0140] The phrase "showing an increasing trend" indicates that the overall size of the lateral wrist guard 113 protruding from the writing area 111 increases. For example, this could mean a continuous increase, or an increase followed by a decrease. Specifically, "increases first, then decreases" means that the size of the lateral wrist guard 113 protruding from the writing area 111 first experiences an increasing phase, then a decreasing phase, but even during the decreasing phase, the size of the lateral wrist guard 113 protruding from the writing area 111 still increases. In other words, during the decreasing phase, the lateral wrist guard 113 still protrudes relative to the writing area 111.

[0141] The phrase "increasing first and then decreasing" describes the initial increase followed by a decrease in the size of the lateral wrist rest 113 protruding from the writing area 111. During the decreasing phase, the size of the lateral wrist rest 113 protruding from the writing area 111 may continue to increase or remain unchanged. That is, during the decreasing phase, the lateral wrist rest 113 may still protrude relative to the writing area 111, or it may retract at its end into the writing area 111. Here, "end" refers to the end of the lateral wrist rest 113 extending towards the user.

[0142] For example, with Figures 1 to 3 For example, it is shown that the size of the side wrist guard 113 protruding from the writing part 111 increases as it extends toward the user along the direction of the side wrist guard 113.

[0143] This arrangement, with the writing pad 110 generally facing the user's side in an open manner, not only provides the user with a wider range of use and better supports the user's wrist and / or elbow, but also saves space on the side of the wrist rest 113 away from the user.

[0144] Based on some embodiments of this application, please continue to refer to Figures 1 to 3The writing pad 110 includes a writing section 111 located in the writing area, a horizontal wrist rest 112 located in the wrist rest area, and a lateral wrist rest 113. The writing section 111, the horizontal wrist rest 112, and the lateral wrist rest 113 together form an upward-facing first streamlined curved surface M1. The horizontal wrist rest 112 is connected to the side of the writing section 111 closest to the user. The horizontal wrist rest 112 and the writing section 111 together constitute a combined part, and the lateral wrist rest 113 is provided on both sides of the combined part along a first direction. The first direction 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.

[0145] Since the assembly includes a transverse wrist guard 112 and a writing section 111, when a lateral wrist guard 113 is provided on both sides of the assembly along the first direction, the lateral wrist guard 113 may be connected to the writing section 111, the lateral wrist guard 113 may be connected to the transverse wrist guard 112, or the lateral wrist guard 113 may be connected to both the writing section 111 and the transverse wrist guard 112.

[0146] For example, with Figures 1 to 3 For example, the lateral wrist guard 113 is connected to both the writing section 111 and the horizontal wrist guard 112.

[0147] The advantages of the horizontal wrist guard 112 and the lateral wrist guard 113 can be seen in the illustrations of some of the foregoing embodiments, and will not be repeated here. By controlling the connection between the writing unit 111, the lateral wrist guard 113, and the horizontal wrist guard 112, different usage needs can be met while satisfying the wrist guard function, thereby improving the practicality and adaptability of the writing tablet 110.

[0148] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The side of the wrist rest 113 extends from the side away from the user to the middle area of ​​the side of the writing section 111.

[0149] Thus, when the contact area between the user and the writing pad 110 moves to the side of the writing section 111, the lateral wrist rest 113 can provide a wider range of support for the contact area, allowing the user to receive continuous and comfortable support during use. Furthermore, since the writing section 111 is located on the side furthest from the user, it is used less frequently. Therefore, extending the lateral wrist rest 113 from the side furthest from the user to the central area of ​​the side of the writing section 111 simplifies the overall structure.

[0150] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 Along the direction in which the lateral wrist guard 113 extends toward the user, the size of the lateral wrist guard 113 protruding from the assembly tends to increase.

[0151] The phrase "showing an increasing trend" can be understood with reference to the situations illustrated in some of the aforementioned embodiments, and is not specifically limited here.

[0152] This arrangement, with the writing pad 110 generally facing the user's side in an open manner, not only provides the user with a wider range of use and better supports the user's wrist and / or elbow, but also saves space on the side of the wrist rest 113 away from the user.

[0153] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 The side of the wrist guard 113 opposite to the assembly and the side of the assembly where the side wrist guard 113 is provided form a fourth streamlined curved surface M4.

[0154] For example, with Figures 1 to 3 For example, the lateral wrist guard 113 is connected to one side of the writing unit 111 and to the lateral wrist guard 112, thus the second streamlined surface M2 and the third streamlined surface M3 shown in the aforementioned embodiments constitute the fourth streamlined surface M4. Of course, the fourth streamlined surface M4 formed will be different depending on the connection position between the lateral wrist guard 113 and the assembly unit. It can be understood by referring to the lateral streamlined surfaces formed by the lateral wrist guard 113 being connected to the writing unit 111 and the lateral wrist guard 112 shown in the aforementioned embodiments, which will not be elaborated here.

[0155] Thus, the advantages of forming the fourth streamlined surface M4 can be understood by referring to the lateral streamlined surfaces illustrated in some of the aforementioned embodiments, which will not be elaborated upon here. Therefore, by forming the fourth streamlined surface M4, the risk of scratches and abrasions caused by bumps and collisions can be reduced, thereby improving safety during use.

[0156] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 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.

[0157] For example, with Figures 1 to 3 For example, this illustration shows a scenario where both the lateral wrist guard 113 and the lateral wrist guard 112 are equipped with anti-slip strips F1. Specifically, both the lateral wrist guard surface C and the lateral wrist guard surface H are equipped with anti-slip strips F1.

[0158] For example, with Figure 4 For example, Figure 4This 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 113 has an anti-slip layer F2 and the transverse wrist guard 112 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.

[0159] 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.

[0160] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing board 110 is a one-piece molded structure; or, the writing board 110 includes a writing part 111 located in the writing area, a horizontal wrist guard 112 located in the wrist guard area, and a side wrist guard 113; the writing part 111, the horizontal wrist guard 112, and the side wrist guard 113 together form an upwardly facing first streamlined curved surface M1; at least two of the writing part 111, the horizontal wrist guard 112, and the side wrist guard 113 are one-piece molded structures.

[0161] For example, the side wrist guard 113 and the lateral wrist guard 112 can be a one-piece molded structure, and the one-piece side wrist guard 113 and the lateral wrist guard 112 can be detachably connected to the writing part 111.

[0162] For example, one of the horizontal wrist guard 112 and the side wrist guard 113 is integrally formed with the writing part 111, while the other is detachably connected to the writing part 111. For instance, the horizontal wrist guard 112 and the writing part 111 are integrally formed, and the side wrist guard 113 is detachably connected to the writing part 111 and / or the horizontal wrist guard 112 via magnetic attraction, threads, snap-fit, or other methods. As another example, the side wrist guard 113 and the writing part 111 are integrally formed, and the horizontal wrist guard 112 is detachably connected to the writing part 111 and / or the side wrist guard 113 via threads, magnetic attraction, slide rail, or other methods.

[0163] For example, the writing section 111, the horizontal wrist guard 112, and the side wrist guard 113 are integrally formed.

[0164] Thus, by configuring the writing board 110 as a one-piece structure, or configuring at least two of the three components—the writing section 111, the horizontal wrist rest 112, and the side wrist rest 113—as a one-piece structure, the writing board 110 not only has a certain structural strength, but also facilitates maintaining the integrity of the overall structure of the writing board 110, thereby improving the product's service life and ease of maintenance.

[0165] According to some embodiments of this application, at least two of the writing section 111, the horizontal wrist guard 112, and the lateral wrist guard 113 are detachably connected.

[0166] Detachable connections can be made using threaded, magnetic, or sliding rail methods, among others, and no specific restrictions are imposed here.

[0167] For example, please continue to refer to Figures 1 to 4 and in conjunction with reference Figure 6 , Figure 6 The diagram shows a partial structural diagram of the side wrist guard 113 in some embodiments of this application. A detachable side wrist guard 113 is also provided on both sides of the writing part 111. Each side wrist guard 113 is provided with a slide rail 1131 and the side of the writing part 111 is provided with a sliding groove (not shown in the figure). The side wrist guard 113 and the writing part 111 are detachably connected through the matching sliding groove and slide rail 1131.

[0168] Thus, at least two of the writing section 111, the horizontal wrist guard 112, and the lateral wrist guard 113 are detachably connected, which is convenient to manufacture and maintainable.

[0169] It should be noted that when the writing pad 110 includes a writing section 111 and a horizontal wrist rest 112, the writing section 111 and the horizontal wrist rest 112 can be integrally formed or detachably connected. When the writing pad 110 includes a writing section 111 and a side wrist rest 113, the writing section 111 and the side wrist rest 113 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.

[0170] It should also be noted that the above embodiments illustrate various implementation methods of the writing board 110. When the writing board 110 includes a horizontal wrist guard 112 and a side wrist guard 113, there are no specific restrictions on the structural form and implementation method of the horizontal wrist guard 112 and the side wrist guard 113, as long as they can achieve the required wrist protection function.

[0171] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The lower end face of the support structure 120 is used to support the placement structure. The contact method between the lower end face of the support structure 120 and the placement structure includes surface contact.

[0172] The support structure 120 is mainly used to support the writing board 110 so that the writing surface W of the writing board 110 is arranged at an angle.

[0173] Thus, by setting the support structure 120 to support the writing board 110, and making the contact between the support structure 120 and the placement structure include surface contact, not only can the writing surface W of the writing board 110 be tilted, but it also helps to improve the mechanical stability of the overall structure.

[0174] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The support structure 120 has a hollow structure Q, or the support structure 120 and the writing board 110 together define the hollow structure Q.

[0175] 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 120, it can be formed by removing a portion of the material from the support structure 120, or it can be formed by connecting multiple components to the support structure 120. When the support structure 120 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 120 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.

[0176] Thus, by setting up 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.

[0177] According to some embodiments of this application, the lower end face of the support structure 120 is used to support the placement structure, which is a table.

[0178] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The support structure 120 includes a support base plate 121 and a support side plate 122.

[0179] The supporting base plate 121 is used to support the placement structure. One end of the supporting base plate 121 and one end of the supporting side plate 122 are spaced apart and both are connected to the lower end surface of the writing board 110. The other end of the supporting base plate 121 is connected to the other end of the supporting side plate 122. And / or, the supporting base plate is used to support the placement structure, which is a table.

[0180] The supporting base plate 121 and the supporting side plate 122 refer to components with a certain length. The end of the supporting side plate 122 connected to the supporting base plate 121 may or may not be in contact with the placement structure; no specific restrictions are imposed here.

[0181] By setting up a supporting base plate 121 and supporting side plates 122, the stability of the overall structure can be improved. When the hollow structure Q is formed, the supporting base plate 121, supporting side plates 122 and writing board 110 can roughly form a triangular support structure, which not only improves the structural stability but also facilitates manufacturing.

[0182] It should be noted that a triangular support structure refers to a mechanical structure that uses three fulcrums or three supporting sides to roughly form a triangle or triangular body, and utilizes the stability of the triangle to achieve stable support.

[0183] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing area, on the side facing away from the user, points towards the side of the writing area facing the user. The support base plate 121, connected to one end of the writing board 110, is located downstream of the end of the support base plate 121 that connects to the support side plate 122. The end of the support side plate 122 connected to the writing board 110 is positioned closer to the side of the writing area facing the user than the end of the support side plate 122 connected to the support base plate 121. The end of the support side plate 122 connected to the support base plate 121 points towards the end of the support side plate 122 connected to the writing board 110 and is angled to the horizontal plane.

[0184] This not only allows for a tilted writing surface (W), but also improves the overall structural stability, thus reducing the likelihood of shaking or deformation during use.

[0185] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The support structures 120 are arranged in pairs, and the lower end face of the writing board 110 is provided with a support structure 120 at each end along the first direction.

[0186] The pairing of support structures 120 means that there are two support structures 120, located on both sides or symmetrically on the writing board 110. The two support structures 120 together constitute the structure supporting the writing board 110.

[0187] Thus, by setting up paired support structures 120, it is beneficial to further enhance the structural stability and anti-overturning ability.

[0188] It should be noted that when the support structure 120 and the writing board 110 jointly define the hollow structure Q, the writing board 110 and the support structure 120 form a triangular support structure, and the lower end face of the writing board 110 is provided with a support structure 120 at each end along the first direction, not only can the stability of the overall structure be further improved on the basis of achieving lightweight design, but it also makes it easier for users to move the overall structure through the hollow structure Q.

[0189] Based on some embodiments of this application, please continue to refer to Figures 1 to 4The writing board 110 includes a snap-fit ​​part 114 and a horizontal wrist guard plate 112 located in the wrist guard area, with the snap-fit ​​part 114 connected to the horizontal wrist guard plate 112.

[0190] The snap-fit ​​portion 114 is adapted to cooperate with the placement structure to limit the writing board 110; or, the snap-fit ​​portion 114 is adapted to cooperate with the placement structure, which is a tabletop; or, the snap-fit ​​portion 114 is adapted to connect with the tabletop.

[0191] Conventional writing boards rest directly on the surface of a table, with a friction pad underneath to fix the writing board 110 relatively to the table, facilitating writing or reading. However, due to users' posture and writing habits, there is a risk that they 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 snap-fit ​​part 114 suitable for cooperating with the placement structure to connect 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.

[0192] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The snap-fit ​​portion 114 is adapted to snap-fit ​​and fix to a placement structure (e.g., a tabletop) to secure the writing board 110 above the placement structure. It should be noted that the snap-fit ​​portion 114 can be fixed to the placement structure by providing a telescopic snap-fit ​​rod, allowing for a fixed connection with the placement structure as the thickness of the placement structure changes.

[0193] This will help improve the adaptability of the streamlined writing board's posture corrector 100 and meet the needs of different users.

[0194] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing board 110 also includes a writing section 111 located in the writing area, and a protrusion 115. A horizontal wrist rest 112 is connected to the side of the writing section 111 facing the user, and a snap-fit ​​portion 114 and a protrusion 115 are provided on the side of the horizontal wrist rest 112 opposite to the writing section 111. The snap-fit ​​portion 114 and the protrusion 115 are connected, and the snap-fit ​​portion 114 and the protrusion 115 on the side opposite to the horizontal wrist rest 112 form a fifth streamlined curved surface M5; and / or, the posture corrector 100 of the streamlined writing board also includes a correction element 130, which is rotatably connected to the protrusion 115.

[0195] For example, the snap-fit ​​portion 114 and the protrusion 115 can be formed into a fifth streamlined curved surface M5 by rounded chamfering.

[0196] Corrector 130 is a functional component that uses physical limits to help users maintain a more correct body posture.

[0197] Thus, by utilizing the latching portion 114 and the protrusion 115 to form the fifth streamlined curved surface M5, not only can the risk of injury to the user be reduced, but the protrusion 115 can also limit the user's movement. Simultaneously, since the fifth streamlined curved surface M5 is formed by using the protrusion 115 facing away from the wrist guard area, the user's arm can be placed at the fifth streamlined curved surface M5, improving the user experience. When the fifth streamlined curved surface M5 is formed by rounded chamfers on both sides of the protrusion 115 and the latching portion 114, it is easier to support and / or accommodate the user's arm. By rotatably connecting the corrector 130 to the protrusion 115, the position of the corrector 130 can be adjusted to better meet the user's needs.

[0198] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing pad 110 also includes a protrusion 115 located on the side of the wrist guard facing the user, and an adjustment member 130. The adjustment member 130 is located on the protrusion 115.

[0199] The protrusion 115 is located on the side of the wristband facing the user. The corrective element 130 is mounted on the protrusion 115, allowing for closer contact with the limb area requiring correction. This provides more direct physical contact to help the user maintain a more correct body posture. Simultaneously, the areas on either side of the protrusion 115 also provide more auxiliary space due to its relative protrusion, such as facilitating support and / or accommodating the user's arm, as mentioned above.

[0200] Thus, through the cooperation of the corrective element 130 and the protrusion 115, not only can the correction be more direct and effective, but it can also take into account the comfort and adaptability of use.

[0201] According to some embodiments of this application, the protrusion 115 forms a fifth streamlined curved surface M5 on the side opposite to the wrist guard area.

[0202] Thus, by utilizing the protrusion 115 to form the fifth streamlined curved surface M5, not only can the risk of injury to the user be reduced, but the protrusion 115 can also be used to limit the user's movement. At the same time, since the fifth streamlined curved surface M5 is formed by utilizing the side of the protrusion 115 away from the wrist guard area, the user's arm can be placed at the fifth streamlined curved surface M5, improving the user's experience.

[0203] It should be noted that when the aforementioned snap-fit ​​portion 114 is provided, the snap-fit ​​portion 114 and the protrusion 115 can be connected, and the snap-fit ​​portion 114 and the protrusion 115 form a fifth streamlined curved surface M5 on the side opposite to the transverse wrist guard plate 112. Further details will not be provided here.

[0204] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The straightening element 130 is rotatably connected to the protrusion 115.

[0205] For example, in conjunction with reference Figure 5 , Figure 5 This is a schematic diagram of the corrector 130 in some embodiments of this application. The protrusion 115 is provided with a receiving groove 1151, which is adapted to be rotatably connected with the rotating end 134 of the corrector 130. The rotatable connection between the corrector and the writing board 110 is realized by the arrangement of the receiving groove 1151 and the rotating end 134.

[0206] In this way, the position of the corrector 130 can be adjusted so that the corrector 130 better meets the user's needs.

[0207] Based on some embodiments of this application, please continue to refer to Figures 1 to 5 The corrective component 130 includes a connecting portion 131, a supporting portion 132, an elastic pad 133, and a rotating end 134. The connecting portion 131 and the supporting portion 132 are vertically arranged. The rotating end 134 is located at the bottom of the connecting portion 131, and the supporting portion 132 is located at the top of the connecting portion 131. The rotating end 134 is rotatably connected to the protrusion 115 to achieve relative rotation between the corrective component 130 and the writing board 110. Each end of the supporting portion 132 has an elastic pad 133 facing the user. The elastic pads 133 provide protection for the user's body.

[0208] For example, the support part 132 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.

[0209] For example, the connecting part 131 is a telescopic adjustment rod, and the height of the connecting part 131 can be adjusted to accommodate users of different heights.

[0210] Thus, by configuring the corrective component 130 to include a connecting part 131, a support part 132, an elastic pad 133, and a rotating end 134, it can not only better adjust the user's sitting posture, but also protect the user's body.

[0211] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing board 110 includes a writing section 111 located in the writing area, a wrist guard located in the wrist guard area, a corrector 130, and a reading board 140. The wrist guard is at least connected to the side of the writing section 111 facing the user, the corrector 130 is located on the side of the wrist guard opposite to the writing section 111, and the reading board 140 is connected to the writing section 111. The bottom of the corrector 130, the bottom of the writing section 111, and the bottom of the reading board 140 rise sequentially.

[0212] For example, the wrist guard portion can be the horizontal wrist guard plate 112 illustrated in some of the foregoing embodiments. Of course, the wrist guard portion can also include the horizontal wrist guard plate 112 and the lateral wrist guard plate 113. No specific limitations are imposed here.

[0213] The bottom of the corrector 130, the bottom of the writing section 111, and the bottom of the reading plate 140 rise sequentially; that is, the bottom of the corrector 130, the bottom of the writing surface W, and the bottom of the reading plate 140 rise sequentially. For example, when the writing surface W is inclined, the inclined writing surface W can be used to make the bottom of the corrector 130, the bottom of the writing surface W, and the bottom of the reading plate 140 rise sequentially.

[0214] For example, the corrector 130 can be configured to be adjustable relative to the writing surface 110. For instance, the corrector 130 is rotatably connected to the protrusion 115 and is retractable relative to the writing surface 110, thus allowing the posture corrector 100 of the streamlined writing surface to have different usage states. In one usage state of the posture corrector 100 of the streamlined writing surface, the top of the corrector 130 is higher than the top of the writing section 111, and the top of the reading board 140 is higher than the top of the corrector 130; that is, the top of the writing surface W, the top of the corrector 130, and the top of the reading board 140 are successively raised. In another usage state of the posture corrector 100 of the streamlined writing surface, the corrector 130 can be retracted by rotating and retracting it below the placement structure.

[0215] 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 130, so that the reading board 140 can accommodate larger books or tablets.

[0216] Thus, by controlling the positional relationships between the bottom of the corrector 130, 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 130, 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 130, 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 130, it facilitates eye-level reading during use, mitigating fatigue caused by the corrector 130 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 130, the posture corrector as a whole better meets the user's needs, improving the user experience.

[0217] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 4 and in conjunction with reference Figure 7 , Figure 7 The following is a schematic diagram of the structure of the reading board 140 in some embodiments of this application. The writing board 110 includes a writing section 111 located in the writing area. The posture corrector 100 of the streamlined writing board also includes the reading board 140, which is disposed in the writing section 111.

[0218] For example, the reading plate 140 is located on the side of the writing section 111 that is tilted upwards.

[0219] Thus, by setting up a reading board 140 on the writing section 111 and placing books on the reading board 140, the user's reading posture can be improved.

[0220] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 4 and Figure 7 The writing section 111 has a slot X and a positioning groove D, which together form a mounting area. The reading plate 140 is connected to the writing section 111 via the mounting area.

[0221] For example, the writing pad 110 has two slots X and a positioning groove D on the side opposite to the protrusion 115. The positioning groove D and the slots X form the mounting area of ​​the reading pad 140. The surface area of ​​the mounting area is 5%-25% of the surface area of ​​the writing pad 110, preferably 8%. Within the mounting area, the slots X can be used to insert a tablet computer, and the positioning groove D can be used to mate with the reading pad 140.

[0222] Thus, by setting the positioning groove D and the slot X to form an installation area, the installation of the reading board 140 is facilitated. When the reading board 140 and the writing unit 111 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 unit 111 detachable can improve the user's convenience.

[0223] For example, please continue to refer to Figure 1 , Figure 4 and Figure 7 The surface area of ​​the reading board 140 is 50%-80% of the surface area of ​​the writing board 110.

[0224] 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 in order to improve the situation where the reading board 140 is too large or too small and has an adverse effect on the writing board 110.

[0225] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 4 and Figure 7 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.

[0226] 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.

[0227] For example, such as Figure 1 , Figure 2 and Figure 7 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.

[0228] For example, such as Figure 7 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 144 is hinged in the placement slot 1451. The placement slots 1451 and the book clip 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.

[0229] For example, such as Figure 7 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.

[0230] For example, such as Figure 1 , Figure 4 and Figure 7 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 placement plane of the placement structure, 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.

[0231] In this way, by configuring various structures of the reading board 140, the user's comfort and convenience can be improved.

[0232] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 This application provides a posture corrector 100 for a streamlined writing board. The posture corrector 100 for the streamlined writing board includes a writing board 110, which is suitable for being placed 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 onto the table or the ground along the writing area.

[0233] In some embodiments, please continue to refer to Figures 1 to 4 The writing surface W is inclined to the horizontal plane. The wrist guard area is provided with a horizontal wrist guard plate 112. One side of the horizontal wrist guard surface H of the horizontal wrist guard plate 112 is connected to the writing surface W.

[0234] In some embodiments, please continue to refer to Figures 1 to 4 The cross-section of the first streamlined surface M1 is a curve. Specifically, the cross-section of the first streamlined surface M1 can be considered as the section cut by the first streamlined surface M1 through the aforementioned first reference surface. Since the first streamlined surface M1 is a surface, its cross-section is a line. That is, in this embodiment, the cross-section of the first streamlined surface M1 is a curve.

[0235] In some embodiments, please continue to refer to Figures 1 to 4 The posture corrector 100 of the streamlined writing board also includes a supporting side plate 122 and a supporting base plate 121.

[0238] In some embodiments, please continue to refer to Figures 1 to 4The posture corrector 100 of the streamlined writing board also includes a corrector 130, which is rotatably connected to the protrusion 115. The width of the corrector 130 is smaller than the width of the writing board 110.

[0239] In some embodiments, please continue to refer to Figures 1 to 4 The protrusion 115 is provided with a receiving groove 1151, which is adapted to be rotatably connected to the rotating end 134 of the straightening member 130.

[0240] In some embodiments, please continue to refer to Figures 1 to 4 The writing board 110 has a slot X and a positioning groove D on the side opposite to the protrusion 115. 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.

[0241] In some embodiments, please continue to refer to Figures 1 to 4 The streamlined writing board posture corrector 100 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.

In one usage state of the posture corrector 100 of the streamlined writing board, the top of the corrector 130 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 130.

[0243] In some embodiments, please continue to refer to Figures 1 to 4 The width of the reading plate 140 is greater than the width of the corrector 130.

[0244] In some embodiments, please continue to refer to Figures 1 to 4 A lateral wrist guard 113 is provided on each side of the writing board 110. The lateral wrist guard 113 is connected to the writing board 110, and a fourth streamlined curved surface M4 is formed between the lateral wrist guard 113 and the writing board 110.

[0246] In some embodiments, please continue to refer to Figures 1 to 4 The surface area of ​​the lateral wrist guard 113 is 3%-15% of the surface area of ​​the writing board 110.

[0247] In some embodiments, please continue to refer to Figures 1 to 4 The horizontal wrist guard 112 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.

[0248] According to the above embodiments, the streamlined writing tablet posture corrector 100 provided in this application includes at least a writing tablet 110. The writing tablet 110 is suitable for placement on a table. 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 positioned 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 onto the table or the ground along the writing area. When the writing tablet 110 is placed at an angle on the table, the writing area and the wrist rest area together form the first streamlined curved surface M1. When an item falls along the writing tablet 110, the presence of the first streamlined curved surface M1 prevents the item from falling, providing the user with a better user experience.

The supporting side plate 122 is set at an acute angle to the horizontal plane, and there is a hollow area between the supporting side plate 122, the writing tablet 110, and the supporting base plate 121. The supporting side plate 122 and the supporting base plate 121 jointly support the writing tablet 110, and the hollow area reduces the overall weight of the entire device.

[0252] According to the above embodiments, the posture corrector 100 of the streamlined writing board provided in this application has a protrusion 115 on the side of the wrist guard area away from the writing area, and a fifth streamlined curved surface M5 is provided on the protrusion 115 in the direction away from the writing board 110. The fifth streamlined curved surface M5 is used to place the user's arm and improve the user's experience.

[0253] According to the above embodiments, the posture corrector 100 of the streamlined writing board provided in this application has a fifth streamlined curved surface M5 formed by rounded chamfers on both sides of the protrusion 115 and the wrist support area, so as to support the user's arm.

[0254] According to some of the above embodiments, the posture corrector 100 of the streamlined writing board provided in this application also includes a corrector 130, which is rotatably connected to the protrusion 115. The width of the corrector 130 is smaller than the width of the writing board 110, so that the corrector can better meet the user's usage needs.

[0255] According to some of the above embodiments, the posture corrector 100 of the streamlined writing board provided in this application has a receiving groove 1151 on the protrusion 115. The receiving groove 1151 is adapted to be rotatably connected to the rotating end 134 of the corrector 130. The rotational connection between the corrector 130 and the writing board 110 is realized by the arrangement of the receiving groove 1151 and the rotating end 134.

[0256] According to the above embodiments, the streamlined writing board posture corrector 100 provided in this application has a slot X and a positioning groove D on the side of the writing board 110 away from the protrusion 115. The positioning groove D and the slot X form an installation area. The surface area of ​​the installation area is 5%-25% of the surface area of ​​the writing board 110. The installation area is set to facilitate the subsequent installation of the reading board 140.

[0257] According to the above embodiments, the streamlined writing tablet posture corrector 100 provided in this application also includes a reading board 140. The reading board 140 is connected to the writing tablet 110 through a mounting area. The surface area of ​​the reading board 140 is 50%-80% of the surface area of ​​the writing tablet 110. Items are placed on the reading board 140, and the surface area of ​​the reading board 140 is set to conform to the user's usage habits. The reading board 140 is designed to avoid being too large or too small, which could adversely affect the writing tablet 110.

[0258] According to the above embodiments, the streamlined writing tablet posture corrector 100 provided in this application has a reading board 140 with a width smaller than that of the writing tablet 110. The bottom of the corrector 130, the bottom of the writing surface W, and the bottom of the reading board 140 are progressively raised. In one usage state of the streamlined writing tablet posture corrector 100, the top of the corrector 130 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 130. By progressively raising the bottom of the corrector 130, the bottom of the writing surface W, and the bottom of the reading board 140, and with the top of the corrector 130 higher than the top of the writing surface W and the top of the reading board 140 higher than the top of the corrector 130, a roughly "U"-shaped structure is formed, ensuring that the user has a good line of sight during reading and writing. The width of the reading board 140 is greater than the width of the corrector 130, so that the reading board 140 can accommodate larger books or tablet computers.

[0259] According to the above embodiments, the streamlined writing tablet posture corrector 100 provided in this application has a lateral wrist rest 113 on each side of the writing tablet 110. The lateral wrist rest 113 is connected to the writing tablet 110, and a fourth streamlined curved surface M4 is formed between the lateral wrist rest 113 and the writing tablet 110. The lateral wrist rest 113 supports the user's elbow or wrist, preventing it from being suspended in the air. The fourth streamlined curved surface M4 avoids straight lines from causing injury to the user's elbow or wrist.

[0260] According to the above embodiments, the posture corrector 100 of the streamlined writing board provided in this application has a lateral curved surface on the side of the side of the wrist rest 113, and the straight surface of the side of the writing board 110 and the lateral curved surface of the wrist rest 113 form a fourth streamlined curved surface M4 to prevent straight lines from causing injury to the user's wrist or elbow.

[0261] According to the above embodiments, the lateral wrist rest 113 of the streamlined writing board posture corrector 100 provided in this application has a surface area of ​​3%-15% of the surface area of ​​the writing board 110. The lateral wrist rest 113 does not need to be too large, reducing the production cost for enterprises.

[0262] According to the above embodiments, the posture corrector 100 of the streamlined writing board provided in this application has a horizontal wrist guard 112 connected to the snap-fit ​​part 114 of the writing board 110. The snap-fit ​​part 114 is adapted to be connected to the table, and the connection between the writing board 110 and the table is realized through the snap-fit ​​part 114.

[0263] The following description, in conjunction with the embodiments illustrated in the above examples, provides an exemplary description of the posture corrector 100 for the streamlined writing board provided in this application, but it is not intended to be limited thereto.

[0264] Example 1

[0265] like Figure 1-3 One specific embodiment of the posture corrector 100 of the streamlined writing board shown in Figures 5-7 includes: a writing board 110, and a correction element 130 and a reading board 140 respectively connected to the writing board 110.

[0266] like Figure 1 and Figure 2 As shown, the writing board 110 has a writing area and a wrist rest area. The wrist rest area is oriented towards 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.

[0267] In some embodiments, the wrist guard area is provided with a horizontal wrist guard plate 112. One side of the horizontal wrist guard surface H of the horizontal wrist guard plate 112 is smoothly connected to the writing surface W. The writing surface W and the horizontal wrist guard surface H form a first streamlined curved surface M1, and the cross-section of the first streamlined curved surface M1 is curved. By forming the first streamlined curved surface M1, it is possible to prevent items from falling along the writing area onto the table or the ground.

[0268] It should be noted that in this embodiment, the horizontal wrist rest surface H refers to the entire upper surface of the horizontal wrist rest plate 112, and the writing surface W refers to the upper surface of the writing area of ​​the writing board 110. It should also be noted that in this embodiment, 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.

[0269] In some embodiments, the writing board 110 has a protrusion 115 on the side facing the user, wherein the protrusion 115 has a receiving groove 1151, the receiving groove 1151 is adapted to be rotatably connected to the rotating end 134 of the corrector 130, and the side of the protrusion 115 away from the writing area has a fifth streamlined curved surface M5. The setting of the fifth streamlined curved surface M5 can reduce the risk of injury to the user and can limit the protrusion 115 to the user.

[0270] In some implementations, such as Figure 2 As shown, the writing board 110 also has a snap-fit ​​part, which is connected to the protrusion. The snap-fit ​​part is suitable for snapping and fixing to the tabletop to secure the writing board 110 above the tabletop. It should be noted that the snap-fit ​​part can be fixed to the tabletop by setting a telescopic snap-fit ​​rod, and can be fixedly connected to the tabletop as the thickness of the tabletop changes.

[0271] In some implementations, such as Figure 2 As shown, the writing tablet 110 has two slots and a positioning groove on the side opposite to the protrusion. The positioning groove and slots form the mounting area of ​​the reading tablet, and 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 are used to insert the tablet computer, and the positioning groove is used to mate with the reading tablet.

[0272] In some implementations, such as Figure 1 and Figure 2 As shown, the protrusion has a fifth streamlined curved surface M5 facing away from the writing board 110. That is, the fifth streamlined curved surface M5 is formed between the protrusion and the snap-fit ​​part. Specifically, the sides of the protrusion and the wrist guard area are formed with rounded chamfers to create the fifth streamlined curved surface M5. By forming the fifth streamlined curved surface M5, the user's arm can be accommodated and supported.

[0273] In some implementations, such as Figure 1 As shown, the posture corrector 100 of the streamlined writing board also includes a supporting side plate 122 and a supporting base plate 121. The supporting side plate 122 and the supporting base plate 121 are fixedly connected to the writing board 110. The supporting base plate 121 is the plate that contacts the plane of the tabletop, and the supporting side plate 122 is the plate that is set at an acute angle to the plane of the tabletop. The area between the supporting side plate 122, the writing board 110, and the supporting base plate 121 is a hollow area, which forms a hollow structure Q.

[0274] In some implementations, such as Figure 1 , Figure 2 and Figure 6 As shown, the writing pad 110 also has a detachable side wrist rest 113 on each side. Each side wrist rest 113 has a slide rail 1131, 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 1131. It should be noted that the surface area of ​​the side wrist rest 113 is 3%-15% of the surface area of ​​the writing pad 110, preferably 5%. The side wrist rest 113 only supports the user's elbow and / or wrist and does not need to be too large. Figure 1 and Figure 2 As shown, a fourth streamlined curved surface M4 is formed between the lateral wrist rest 113 and the writing board 110. That is, the side of the lateral wrist rest 113 has a lateral curved surface, and the straight surface of the side of the writing board 110 and the lateral curved surface of the lateral wrist rest 113 form the fourth streamlined curved surface M4. By forming the fourth streamlined curved surface M4, the risk of injury to the user's elbow or wrist from the straight surface can be reduced. Furthermore, to facilitate lateral support, the writing board 110 also includes a lateral wrist rest 112, which is detachably connected to the writing board 110 via a latch (not shown) and a slot (not shown). It should be noted that the lateral wrist rest 112 is located above the latching part 114. It should be noted that both the lateral wrist rest 113 and the lateral wrist rest 112 are provided with anti-slip strips F1.

[0275] 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 112 is provided, the horizontal wrist guard surface H of the horizontal wrist guard 112 constitutes a portion of the first streamlined curved surface M1. For example, when a lateral wrist guard 113 is provided, the lateral wrist guard surface C of the lateral wrist guard 113 constitutes a portion of the first streamlined curved surface M1. For example, when both the horizontal wrist guard 112 and the lateral wrist guard 113 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.

[0276] It should also be noted that the fourth streamlined surface M4 formed between the lateral wrist rest 113 and the writing board 110 refers to the formation of a fourth streamlined surface M4 between the lateral wrist rest 113 and the "writing section 111 and / or the lateral wrist rest 112," which is determined based on the structure of the writing board 110 and the connection method between the lateral wrist rest 113 and other structures of the writing board 110. That is, the fourth streamlined surface M4 can be the second streamlined surface M2, or it can be the third streamlined surface M3, or it can include both the second streamlined surface M2 and the third streamlined surface M3. No specific limitations are imposed here. This can be understood in conjunction with the situations illustrated in some of the foregoing embodiments, and will not be elaborated upon further here.

[0277] In some implementations, such as Figure 1 and Figure 5 As shown, the orthodontic component 130 includes a connecting portion 131 and a supporting portion 132, wherein the connecting portion 131 and the supporting portion 132 are arranged vertically. The bottom of the connecting portion 131 has a rotating end 134, and the top of the connecting portion 131 has the supporting portion 132. The rotating end 134 is rotatably connected to the protrusion 115 of the writing board 110 to achieve relative rotation between the orthodontic component 130 and the writing board 110. It should be noted that the supporting portion 132 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 131 is a telescopic adjustment rod, allowing adjustment of the height of the connecting portion 131 to accommodate users of different heights. Figure 5 As shown, each end of the support 132 is provided with an elastic pad 133 facing the user, so as to protect the user's body.

[0278] In some implementations, such as Figure 1 , Figure 2 and Figure 7 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, through the cooperation of the slot X and the mounting blocks 143, the reading board 140 can be easily inserted and removed for convenient carrying. Figure 7 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 7As 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 a placement slot 1451, and 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 to clamp the user's book. Figure 7 As 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 body 141. The clamping part 142 further supports the tablet computer, making the tablet computer more stable. Figure 1 and Figure 7 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.

[0279] In some embodiments, the bottom of the adjustable wrist rest of the posture corrector 130, the bottom of the writing surface W, and the bottom of the reading board 140 are raised sequentially to ensure a good viewing angle for the user during writing and reading. Furthermore, in one usage state of the posture corrector 100 of the streamlined writing board, the reading board 140 is positioned higher than the corrector 130, facilitating eye-level reading and preventing fatigue caused by the corrector 130 being too high and the user's gaze looking downwards. In addition, 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 130, so that the overall posture corrector better meets the user's needs and improves the user experience.

[0280] As an alternative implementation, the side wrist rest 113 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 113 and the structure in the writing board 110 can be detachably connected.

[0281] As an alternative implementation, the horizontal wrist rest 112 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 112 and the structure in the writing board 110 can be detachably connected.

[0282] As an alternative implementation, the side wrist guard 113 and the lateral wrist guard 112 can also be integrated as a single unit, and the integrated side wrist guard 113 and lateral wrist guard 112 can be detachably connected to the writing section.

[0283] As an alternative implementation, the first streamlined surface M1 can be a curve of other shapes, such as a convex surface.

[0284] As an alternative implementation, the number of mounting blocks 143 can also be 3, 4, or even more.

[0285] Example 2

[0286] In this embodiment, as Figure 4 As shown, the writing section of the writing board 110 is integrally formed with the side wrist guard 113 and the horizontal wrist guard 112. The anti-slip strip F1 of the side wrist guard 113 is removed, and anti-slip material is applied to the corresponding position of the side wrist guard 113 to form an anti-slip layer F2. The other structures of this embodiment are the same as those of embodiment 1.

[0287] It is understood that the above-described embodiments 1 and 2 do not fully illustrate all the various implementation methods illustrated in the foregoing embodiments. The various ways of forming streamlined curved surfaces and other structural implementation methods illustrated in the foregoing embodiments can be freely combined and implemented, and no specific restrictions are imposed here.

[0288] 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.
