Description

Technical Field

[0002] A reading and writing desk is an auxiliary tool placed on a desktop to facilitate reading and writing. It usually has a support structure with a certain tilt angle, tilting the reading or writing surface towards the user to raise the book towards the user at a certain angle, reducing the user's head-down posture when writing and reading, relieving neck fatigue, and reducing the probability of the user's myopia.

[0003] Typically, the reading and writing desk is placed directly on the surface of the desk without any connection between the two. The desk is stabilized on the desk by its own weight. When reading and writing, the user's elbow rests on the desk and their arm or wrist extends to the reading and writing desk. The connection between the reading and writing desk and the desk is arranged at an obtuse angle, with the arm part hanging in the air and both ends resting on the desk and the reading and writing desk, which causes discomfort for the user and can easily lead to wrist stiffness during long-term use.

[0062] According to some embodiments of this application, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a three-dimensional posture corrector 100 with wrist support function in some embodiments of this application. Figure 2This is a schematic diagram of the structure of a three-dimensional posture corrector 100 with wrist support function in some embodiments of this application, with some structures removed. The three-dimensional posture corrector 100 with wrist support function in the embodiments of this application includes a writing board 110, which has a writing surface 1101. One side of the writing surface 1101 extends obliquely upward to form a main surface 1101a at an angle to the horizontal plane, and the other side of the writing surface 1101 extends along a first direction and a second direction to form a transition surface 1101b. The first direction and the second direction intersect each other.

[0063] The writing surface 1101 can be viewed as the upward-facing surface of the writing pad 110, that is, the user-facing surface. Here, "user-facing surface" refers to the surface that directly contacts the user's body or operational behavior during use. In other words, the user-facing surface is not necessarily the surface directly opposite the user. The writing surface 1101 includes a main surface 1101a and a transition surface 1101b. The main surface 1101a constitutes the main body of the writing surface 1101. One side of the writing surface 1101 extends upward at an angle to the horizontal plane, forming the main surface 1101a. The transition surface 1101b is the portion of the writing surface 1101 that connects to the main surface 1101a. The transition surface 1101b can be used to rest the wrist and elbow, or to rest either the wrist or the elbow. The other side of the writing surface 1101 extends along the first and second directions to form a transition surface 1101b. That is, the transition surface 1101b extends along the first and second directions. It should be noted that the first and second directions are used to characterize the extension state of the transition surface 1101b, reflecting that the transition surface 1101b has a certain length and width, and do not constitute a limitation on the shape change of the transition surface 1101b.

[0064] The first direction and the second direction intersect each other, that is, the first direction and the second direction are set at an angle. The angle between the first direction and the second direction is not specifically limited here.

[0065] Thus, by providing the transition surface 1101b, it can be used to rest the wrist and / or elbow, thereby improving the situation where the wrist and / or elbow are suspended or pressed against the side of the writing tablet 110, and thus improving the comfort of using the writing tablet 110.

[0066] The transition surface 1101b can be used to support the wrist and elbow, or specifically the wrist or elbow. The specific area of ​​the arm that is supported may vary slightly depending on the user's age or the usage scenario. Essentially, the design of the transition surface 1101b provides sufficient support for the user's arm, effectively improving the stiffness caused by incorrect force exertion due to wrist suspension, and enhancing the comfort of using the posture corrector.

[0067] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The area in the writing pad 110 having a transition surface 1101b at least constitutes a support portion 112. The support portion 112 is used to rest the wrist and / or elbow.

[0068] The support portion 112 is a component that can be used to support the wrist and / or elbow. For example, the area in the writing pad 110 having the transition surface 1101b at least constitutes the support portion 112, and in addition to constituting the support portion 112, it may also constitute other functional portions. Other functional portions may be functional portions for placing reading materials or other items, or for assisting writing, etc., and are not specifically limited here.

[0069] Since the support portion 112 is composed of at least a portion of the area in the writing board 110 having the transition surface 1101b, the shape of the transition surface 1101b can be used to form a support portion 112 with greater user comfort, thereby further improving the user's user comfort.

[0070] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The entire other side of the writing surface 1101 extends along the first and second directions to form a transition surface 1101b.

[0071] This allows the coverage area of ​​the transition surface 1101b to extend completely from the other side of the writing surface 1101, forming a continuous area. During use, the position of the user's wrist and / or elbow is not fixed. Because the transition surface 1101b adopts a continuous, gapless structure, it ensures that the user's wrist and / or elbow are always supported by the transition surface 1101b, further improving user comfort. At the same time, because the connection between the extended transition surface 1101b and the main surface 1101a is more complete, the structural stability of the area with the transition surface 1101b in the writing tablet 110 is stronger. When the posture corrector is placed on a table, the integrity of the overall structure allows it to present a complete structural form on the table.

[0072] Of course, in some other embodiments, a portion of the other side of the writing surface 1101 may extend along the first and second directions to form a transition surface 1101b. No specific limitations are imposed here.

[0073] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 Both the first and second directions are parallel to the horizontal plane.

[0074] This results in the transition surface 1101b extending in a shape that roughly extends along a horizontal plane. Since the main surface 1101a extends upwards at an angle, when the transition surface 1101b extends in a shape that roughly extends along a horizontal plane, it presents a more gradual extension compared to the angled main surface 1101a. Thus, the writing surface 1101 as a whole presents an angled main surface 1101a and a transition surface 1101b that gently descends to the horizontal plane. On the one hand, the angled main surface 1101a raises the user's viewing distance compared to a horizontal tabletop, allowing the user to maintain a level gaze while reading and writing, reducing the probability of eye fatigue. On the other hand, the design of the transition surface 1101b not only better conforms to the natural posture of the user's wrist and / or elbow, reducing user fatigue and creating a more stable posture, but also provides smoother support during wrist and / or elbow movements, improving the user's ease of use.

[0075] Of course, in some other embodiments, the first direction and / or the second direction may not be parallel to the horizontal plane, and no specific limitation is made here. For example, the first direction may be the same as or different from the inclination direction of the main body surface 1101a. When the first direction is different from the inclination direction of the main body surface 1101a, the first direction may be a direction further downward relative to the inclination direction of the main body surface 1101a, generally making the extension trend of the transition surface 1101b downward. When the first direction is different from the inclination direction of the main body surface 1101a, the first direction may be a direction further upward relative to the inclination direction of the main body surface 1101a, generally making the extension trend of the transition surface 1101b upward.

[0076] It should be noted that the inclination direction of the main surface 1101a can be understood as the direction from which the end of the main surface 1101a connecting to the transition surface 1101b points away from the end of the main surface 1101a away from the transition surface 1101b. The end of the main surface 1101a connecting to the transition surface 1101b can be considered the lower end of the main surface 1101a, and the end of the main surface 1101a away from the transition surface 1101b can be considered the upper end of the main surface 1101a. It can be understood that the aforementioned upper and lower ends of the main surface 1101a are relative to the inclination direction of the main surface 1101a. A horizontal surface refers to a surface with a certain degree of flatness and does not constitute a limitation on whether an surface is horizontal.

[0077] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The three-dimensional posture corrector 100 with wrist support function provided in this application embodiment includes a writing board 110. The writing board 110 includes a main body 111 and a support part 112. One end of the main body 111 extends upward at an angle relative to the horizontal plane, and the other end of the main body 111 is connected to the support part 112. The support part 112 extends along a first direction and a second direction, and the support part 112 is used to support the wrist and / or elbow. The first direction and the second direction intersect each other.

[0078] The main body 111 is a component constituting the main body of the writing pad 110. The end of the main body 111 that extends upwards at an angle relative to the horizontal plane can be considered the upper end of the main body 111, and the other end of the main body 111 connecting to the support portion 112 can be considered the lower end of the main body 111. It can be understood that the aforementioned upper and lower ends of the main body 111 are relative to the direction of inclination of the main body 111. The direction of inclination of the main body 111 can be understood as the end of the main body 111 connecting to the support portion 112 pointing towards the end of the main body 111 away from the support portion 112. The end of the main body 111 connecting to the support portion 112 is the aforementioned lower end of the main body 111, and the end of the main body 111 away from the support portion 112 is the aforementioned upper end of the main body 111.

[0079] The supporting part 112 is the part of the writing board 110 that is connected to the main body 111 and can be used for support. It should be noted that the first direction and the second direction are used to characterize the extended state of the supporting part 112, reflecting that the supporting part 112 has a certain length and width, and do not constitute a limitation on the shape change of the supporting part 112.

[0080] The first direction and the second direction intersect each other, that is, the first direction and the second direction are set at an angle. The angle between the first direction and the second direction is not specifically limited here.

[0081] Thus, by providing the support part 112, it can be used to rest the wrist and / or elbow, thereby improving the situation where the wrist and / or elbow are suspended in the air or pressed against the side of the writing board 110, and thus improving the comfort of using the writing board 110.

[0082] The support portion 112 can be used to rest the wrist and elbow, or specifically, the area of ​​the arm that is rested may vary slightly depending on the user's age or the usage scenario. Essentially, however, the support portion 112 provides sufficient support for the user's arm, effectively improving stiffness caused by incorrect force exertion in the wrist and / or elbow due to unsupported movement, thus enhancing the comfort of the posture corrector.

[0083] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The main body 111 has an upward-facing main body surface 1101a, and the supporting part 112 has an upward-facing transition surface 1101b. The main body surface 1101a and the transition surface 1101b are connected.

[0084] It is understood that the main surface 1101a and the transition surface 1101b constitute at least a portion of the surface of the writing pad 110 facing upwards; that is, the main surface 1101a and the transition surface 1101b can be regarded as the user-facing surface. The user-facing surface referred to here can be referred to as illustrated in some of the foregoing embodiments, and is not specifically limited here.

[0085] Since the main body 111 is generally inclined and the supporting part 112 extends along the first and second directions, the main body surface 1101a is generally inclined and the transition surface 1101b extends generally along the first and second directions. Therefore, the main body surface 1101a and transition surface 1101b in this application embodiment can be understood by referring to the relevant content of the main body surface 1101a and transition surface 1101b illustrated in some of the foregoing embodiments, and will not be repeated here. The main body surface 1101a and transition surface 1101b illustrated in this application embodiment can constitute the writing surface 1101 mentioned above.

[0086] Thus, since the main body surface 1101a of the main body 111 and the transition surface 1101b of the supporting part 112 are connected, it is beneficial for the user to move continuously between the main body 111 and the supporting part 112 without gaps, thereby improving the user's comfort and enhancing the integrity and structural stability of the overall structure.

[0087] According to some embodiments of this application, the first direction is the user's forward viewing direction, and the second direction is the direction of the edge of the desk opposite to the user; and / or, the first direction is the width direction of the desk, and the second direction is the length direction of the desk; and / or, both the first and second directions are parallel to the horizontal plane.

[0088] For example, the user's forward-looking direction is the width direction of the desk, and the direction of the desk's edge opposite the user is the length direction of the desk. As another example, both the first and second directions are located in a horizontal plane; the first direction is the user's forward-looking direction, i.e., the width direction of the desk; the second direction is the direction of the desk's edge opposite the user, i.e., the length direction of the desk. When the width direction and the length direction of the desk are perpendicular to each other, the first and second directions are set perpendicularly.

[0089] It should be noted that "both the first and second directions lie within the horizontal plane" means that both the first and second directions are directions within the horizontal plane. In other words, the direction vectors corresponding to both the first and second directions belong to the set of vectors within the horizontal plane. Both the first and second direction direction vectors are perpendicular to the normal vector of the horizontal plane.

[0090] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The transition surface 1101b includes an arc-shaped curved surface.

[0091] An arcuate surface is a three-dimensional surface formed by using a curve as its generatrix. Arcuate surfaces are generated from circular or elliptical arcs, and their curvature can be constant or vary systematically. No specific restrictions are imposed here.

[0092] In this way, using curved surfaces for support can make the load distribution more even, thus making the support for the user's wrists and / or elbows more comfortable and reducing the feeling of pressure.

[0093] Of course, in some other embodiments, the transition surface 1101b may also be a plane or a surface with right angles and edges. The transition surface 1101b may also be a parabola, a freeform surface, etc. No specific limitations are made here.

[0094] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The transition surface 1101b includes a smooth transition surface.

[0095] 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.

[0096] By setting smooth transition surfaces, user comfort can be improved while structural durability is enhanced.

[0097] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The surface parallel to the side of the main surface 1101a away from the user and pointing towards the side of the main surface 1101a facing the user, and intersecting with the transition surface 1101b, is the reference surface. The intersection line of the reference surface and the transition surface 1101b is a smooth curve.

[0098] A smooth curve is a curve that satisfies continuity and differentiability at any point, meaning that the curve has no sharp inflection points and the tangent direction has no abrupt changes.

[0099] Because the intersection of the transition surface 1101b and the reference surface is a smooth curve, and the reference surface and the side of the main surface 1101a away from the user are parallel to the side of the main surface 1101a facing the user, the transition surface 1101b extends smoothly from the side away from the user to the side facing the user. Thus, the transition surface 1101b can be roughly regarded as a smooth curve swept along a direction perpendicular to the reference surface. This not only helps to improve the overall integrity and consistency of the product, but also allows for the transition between the desk and the writing board 110 or on the writing board 110 when the user moves their wrist and / or elbow from either the first or second direction, without any sense of obstruction. This further enhances the user's comfort and compliance, ensuring the posture correction effect.

[0100] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The transition surface 1101b is smoothly connected to the main surface 1101a; or, the area of ​​the main surface 1101a away from the transition surface 1101b is set as a plane, and the transition surface 1101b is smoothly connected to the main surface 1101a.

[0101] A smooth connection means that the tangent vectors of the transition surface 1101b and the main surface 1101a at the intersection are in the same direction, without any sharp turns.

[0102] Because the transition surface 1101b is smoothly connected to the main surface 1101a, and the transition surface 1101b gradually extends to a horizontal shape, it not only satisfies the requirement of placing the item at a certain angle, but also ensures that the user's wrist and / or elbow can be stably supported. If the connection between the two is a plane-to-plane connection, it will either form an obvious turning angle or just be an inclined plane. This area will inevitably fail to support the user's wrist or hand, thus improving the user's tactile experience and user comfort.

[0103] It should be noted that the smooth connection between the transition surface 1101b and the main surface 1101a can be achieved by the surface on the transition surface 1101b that connects to the intersection of the transition surface 1101b and the main surface 1101a being a smooth transition surface. Furthermore, the surface on the main surface 1101a that connects to the intersection can also be a smooth transition surface. As long as a smooth connection can be achieved between the transition surface 1101b and the main surface 1101a at the intersection, no specific restrictions are imposed.

[0104] Of course, in some other embodiments, the main body surface 1101a may also include a curved surface, which is not specifically limited here.

[0105] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The lowest point of the main surface 1101a and the transition surface 1101b is located on the transition surface 1101b, and the side of the transition surface 1101b away from the main surface 1101a is located above the lowest point.

[0106] This design results in a generally recessed portion on the transition surface 1101b. Consequently, books, pens, and other items on the writing pad 110 will not roll directly off the writing surface 1101; instead, they will slide down to the transition surface 1101b area under the influence of gravity. The transition surface 1101b also allows for the direct placement of various stationery items for easy access. When the transition surface 1101b includes an arcuate surface with its lowest point located on the arcuate surface, in addition to the advantages of the arcuate surface illustrated in some of the aforementioned embodiments, it further improves the situation where books, pens, and other items on the writing pad 110 will not roll directly off the writing surface 1101, and also makes it easier to place various stationery items.

[0107] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The first direction is a direction that extends obliquely upward away from the main body surface 1101a, and the second direction is perpendicular to the first direction. The transition surface 1101b protrudes from the main body surface 1101a on both sides along the second direction.

[0108] Since the transition surface 1101b protrudes from the main surface 1101a on both sides along the second direction, the writing surface 1101 of the writing tablet 110 is generally open towards the side set by the user. This makes the extension range of the transition surface 1101b in the second direction larger, thereby providing the user with a wider range of use and further supporting the user's wrist and / or elbow.

[0109] It should be noted that, in this embodiment of the application, the shape of the protrusions of the transition surface 1101b on both sides along the second direction relative to the main body surface 1101a is not specifically limited, and can be formed as follows: Figure 1 and Figure 2 The convex shape shown can also form as... Figure 3 and Figure 4 The convex shape is shown in the illustration. Among them, Figure 3 This is a schematic diagram of the overall structure of a three-dimensional posture corrector 100 with wrist support function in some other embodiments of this application. Figure 4 This is a structural schematic diagram of a three-dimensional posture corrector 100 with wrist support function in other embodiments of this application, with some structures removed. For example, the transition surface 1101b and the main body surface 1101a can be smoothly connected on the same side along the second direction.

[0110] For example, with Figure 2 and Figure 4 For example, along the direction that extends upwards at an angle away from the main surface 1101a, the transition surface 1101b, on the side along the second direction, presents a shape that first bulges out relative to the main surface 1101a and then retracts in the opposite direction to the bulging direction. It can be understood that even when it "retracts in the opposite direction to the bulging direction," the side of the transition surface 1101b along the second direction is still bulging out relative to the main surface 1101a.

[0111] It should also be noted that, Figure 3 and Figure 4 Some implementations of the structure shown can also be implemented with reference to the aforementioned embodiments, and will not be repeated here, nor will they be specifically limited.

[0112] According to some embodiments of this application, the first direction is a direction that extends obliquely upward away from the main body surface 1101a, and the second direction is perpendicular to the first direction. A portion of the transition surface 1101b is located downstream of the main body surface 1101a along the oblique extension direction of the main body surface 1101a, and another portion of the transition surface 1101b is located on both sides of the main body surface 1101a along the second direction.

[0113] For example, "a portion of transition surface 1101b" and "another portion of transition surface 1101b" may or may not be connected. No specific restrictions are imposed here.

[0114] Thus, relative to the main surface 1101a, the transition surface 1101b extends approximately along the first direction and protrudes approximately along the second direction, causing the writing surface 1101 of the writing tablet 110 to be set to face the user in a generally open manner, thereby making the extension range of the transition surface 1101b larger, thus providing the user with a wider range of use and further providing more support for the user's wrist and / or elbow.

[0115] Based on some embodiments of this application, please continue to refer to Figure 2 and Figure 4 The writing tablet 110 includes an edge portion 113, which is located at the edge of the region in the writing tablet 110 having a transition surface 1101b.

[0116] For example, the edge portion 113 can be formed by a one-piece molding process. For instance, the edge portion 113 can be a structure that is folded at the edge of the region having the transition surface 1101b in the writing tablet 110. For example, the region having the transition surface 1101b in the writing tablet 110 can be the support portion 112 illustrated in some of the foregoing embodiments.

[0117] Thus, by providing an edge portion 113 at the edge of the area with the transition surface 1101b in the writing board 110, not only can the bending strength of the transition surface 1101b area of ​​the writing board 110 be improved, thereby enhancing the edge's resistance to deformation, but it can also serve as a protective structure at the edge of the transition surface 1101b area of ​​the writing board 110, thereby further enhancing the user's comfort.

[0118] Based on some embodiments of this application, please continue to refer to Figure 2 and Figure 4 One end of the transition surface 1101b that connects to the main body surface 1101a is defined as the starting end e1 of the transition surface 1101b, and the horizontal direction from the starting end e1 to the user is defined as the reference direction. Along the reference direction, the distance between the upper end surface and the lower end surface of the edge portion 113 gradually decreases.

[0119] Thus, the distance between the upper end face and the lower end face of the edge portion 113 gradually changes along the reference direction, so that the distance corresponding to the part of the edge portion 113 closer to the user is smaller. When the edge area of ​​the transition surface 1101b is subjected to user pressure or other forces, the stress distribution decreases gradually from the side away from the user to the side closer to the user, thereby improving the stress concentration in the part closer to the user.

[0120] Based on some embodiments of this application, please continue to refer to Figure 2 and Figure 4 The edge portion 113 is used for support on the placement structure. The placement structure can be a desk.

[0121] Thus, the support provided by the edge portion 113 can further enhance the stability of the writing tablet 110 when the user uses it, as well as the stability when the user places their wrist and / or elbow on the transition surface 1101b.

[0122] It should be noted that, under the conditions that "the distance between the upper and lower surfaces of the edge portion 113 gradually decreases along the reference direction" and "the edge portion 113 is used to support the placement structure," the area of ​​the writing tablet 110 with the transition surface 1101b can be attached to the placement structure. Therefore, when the transition surface 1101b extends in different directions, the area of ​​the writing tablet 110 with the transition surface 1101b can be supported by the edge portion 113. Furthermore, since both the first and second directions are parallel to the horizontal plane, the area of ​​the writing tablet 110 with the transition surface 1101b gradually thins along the direction away from the horizontal center of the writing tablet 110 and is attached to the horizontal plane. The horizontal plane can be understood as the placement plane of the placement structure. The thickness of the area of ​​the writing tablet 110 with the transition surface 1101b can be understood as the distance between the upper and lower surfaces of the edge portion 113. The area with transition surface 1101b in the writing board 110 gradually thins along the direction away from the horizontal center of the writing board 110. That is, along the reference direction, the distance between the upper end surface of the edge portion 113 and the lower end surface of the edge portion 113 gradually decreases.

[0123] In some embodiments, since the area with the transition surface 1101b in the writing pad 110 of this application embodiment has a certain thickness, when the thickness gradually decreases and adheres to the horizontal surface, it can also be regarded as the transition surface 1101b smoothly transitioning to the horizontal surface. This thickness change process ensures that the user's arm will not feel uncomfortable when resting on the edge of the transition surface 1101b. For example, the distance between the upper end surface and the lower end surface of the edge portion 113 can be 1mm to 5mm. In this case, it can be regarded as the area with the transition surface 1101b in the writing pad 110 being in a state of being adhered to the horizontal surface.

[0124] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing pad 110 is a one-piece molded structure; and / or, the three-dimensional posture corrector 100 with wrist support function includes the writing pad 110, which includes a main body 111 and a support part 112. One end of the main body 111 extends obliquely upward relative to the horizontal plane, and the other end of the main body 111 is connected to the support part 112. The support part 112 extends along a first direction and a second direction, and is used to support the wrist and / or elbow. The first direction and the second direction intersect each other, and the main body 111 and the support part 112 are a one-piece molded structure.

[0125] Thus, by configuring the writing board 110 as an integral molded structure, or configuring the main body 111 and the supporting part 112 as an integral molded structure, not only does the writing board 110 have a certain structural strength, but it also makes it easier to maintain the integrity of the overall structure of the writing board 110, thereby improving the product's service life and maintenance convenience.

[0126] Therefore, in conjunction with the situations illustrated in some of the above embodiments, the embodiments of this application mainly provide a transition surface 1101b on the side of the inclined main surface 1101a closer to the user, and a support portion 112 is formed by extending outward from the transition surface 1101b. In this way, on the one hand, it can be used to rest the wrist and / or elbow, so as to improve the wrist and / or elbow from being suspended or pressed on the side of the writing tablet 110, thereby improving the comfort of using the writing tablet 110; on the other hand, by providing a support portion 112 with an edge portion 113, the transition between the writing tablet 110 and the desk is completed, forming the intersection line with a smooth curve as mentioned above, so that the user can improve the situation of feeling obstructed when transitioning between the desk and the writing tablet 110 from either the first direction or the second direction.

[0127] For example, the support portion 112 and the main body portion 111 are detachably connected. As mentioned above, when the support portion 112 has an edge portion 113, since the main body portion 111 is a relatively regular plate-like structure, manufacturing the writing board 110 in an integral form would increase the overall manufacturing difficulty of the writing board 110, and may reduce the product yield. Therefore, this embodiment of the application sets the support portion 112 and the main body portion 111 in a detachable connection form to facilitate their production. Specifically, the support portion 112 and the main body portion 111 are respectively provided with protrusions and grooves at their contact end faces to achieve the assembly and disassembly of the two. Of course, other forms such as adhesion and screw fixing can also achieve a detachable connection between the support portion 112 and the main body portion 111.

[0128] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The three-dimensional posture corrector 100 with wrist support function also includes a support member 120. The support member 120 is disposed on the lower end surface of the writing board 110 and is used to support the placement structure. The contact method between the lower end surface of the support member 120 and the placement structure includes surface contact.

[0129] That is, the main body surface 1101a of the writing tablet 110 is arranged at an upward angle, and a support member 120 is provided on the lower end surface of the writing tablet 110. The upper end surface of the support member 120 abuts against the writing tablet 110, and the lower end surface of the support member 120 can be arranged horizontally. The support member 120 is mainly used to support the writing tablet 110 so that the writing surface 1101 of the writing tablet 110 is arranged at an angle.

[0130] Thus, by setting the support member 120 to support the writing board 110, and making the contact method between the support member 120 and the placement structure include surface contact, not only can the main surface 1101a of the writing board 110 be tilted, but it also helps to improve the mechanical stability of the overall structure.

[0131] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing tablet 110 has one end of its main body 111 extending upward at an angle, and the other end of the main body 111 is connected to a support portion 112 and a support member 120, both of which are supported on the same horizontal plane. The situation where "the support portion 112 is supported on a horizontal plane" can be understood in conjunction with the illustration of the support portion 112 having an edge portion 113 in some of the aforementioned embodiments. Thus, since the support portion 112 and the support member 120 are supported on the same horizontal plane, not only is the overall structural mechanical stability further improved, but the user's comfort is also enhanced when the user's wrist and / or elbow are supported by the support portion 112.

[0132] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The three-dimensional posture corrector 100 with wrist support function has a hollow structure Q, which is provided on the support member 120, or the support member 120 and the writing board 110 together define the hollow structure Q; and / or, the writing board 110 and the support member 120 form a triangular support structure; and / or, the first direction is the direction of the side that extends obliquely upward away from the main body surface 1101a, and the second direction is perpendicular to the first direction; the support members 120 are arranged in pairs, and a support member 120 is provided at each end of the lower end surface of the writing board 110 along the second direction.

[0133] 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 member 120, it can be formed by removing a portion of the material from the support member 120, or it can be formed by connecting multiple components to the support member 120. When the support member 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 member 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.

[0134] A triangular support structure refers to a mechanical structure that uses three fulcrums or three supporting sides to roughly form a triangle or a triangular prism, utilizing the stability of a triangle to achieve stable support. The writing board 110 and the support member 120 constitute a triangular support structure; that is, the lower end face of the writing board 110, the lower end face of the support member 120, and the side face of the support member 120 can roughly form a triangle. In this case, the support member 120 and the writing board 110 can jointly define a hollow structure Q, which can be roughly triangular in shape. Of course, in some other embodiments, the support member 120 can also be roughly triangular in shape. In this case, the support member 120 may or may not have a hollow structure Q; no specific limitations are made here.

[0135] For example, in conjunction with reference Figures 1 to 4 In this embodiment, the support member 120 includes a support plate 121 and a connecting plate 122 disposed on the side of the writing board 110 away from the writing surface 1101. That is, the support plate 121 and the connecting plate 122 are disposed on the lower end surface of the writing board 110. The connecting plate 122 can be arranged horizontally, and the support plate 121 can be arranged vertically. The writing board 110, the support plate 121, and the connecting plate 122 form a triangular support structure to achieve a stable upward tilt of the main body 111 of the writing board 110.

[0136] The pairing of support members 120 means that there are two support members 120, located on both sides or symmetrically on the writing board 110. The two support members 120 together constitute the structure supporting the writing board 110.

[0137] Thus, by setting a hollow structure Q on the support member 120, 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. By configuring the writing tablet 110 and the support member 120 to form a triangular support structure, the stability of the overall structure is further enhanced. By setting the support members 120 in pairs, structural stability and anti-overturning ability are further strengthened.

[0138] It should be noted that when the support member 120 and the writing board 110 jointly define the hollow structure Q, the writing board 110 and the support member 120 form a triangular support structure, and the lower end face of the writing board 110 is provided with a support member 120 at each end along the second 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.

[0139] Based on some embodiments of this application, please continue to refer to Figures 1 to 4The support member 120 includes a support plate 121 and a connecting plate 122 disposed on the lower end face of the writing board 110. The support plate 121 is used to place on the placement structure. One end of the support plate 121 and one end of the connecting plate 122 are spaced apart and both are connected to the lower end face of the writing board 110. The other end of the support plate 121 and the other end of the connecting plate 122 are connected.

[0140] Support plate 121 and connecting plate 122 refer to components with a certain length. The end of connecting plate 122 connected to support plate 121 may or may not contact the placement structure; no specific restrictions are imposed here.

[0141] By setting up the support plate 121 and the connecting plate 122, the support plate 121, the connecting plate 122 and the writing board 110 roughly form the aforementioned triangular support structure, which not only improves the structural stability but also facilitates manufacturing.

[0142] For example, in conjunction with reference Figures 1 to 4 When "support members 120 are arranged in pairs and a support member 120 is provided at each end of the lower end face of the writing board 110 along the second direction", the support plate 121 and the connecting plate 122 are both arranged in pairs, and the two support plates 121 and the two connecting plates 122 are respectively located at both ends of the writing board 110 along the second direction. The arrangement of the support plates 121 and the connecting plates 122 at both ends of the writing board 110 along the second direction can improve the overall stability, reduce the overall weight and manufacturing cost of the three-dimensional posture corrector, and facilitate the user's use of the three-dimensional posture corrector.

[0143] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The lower end surface of the writing pad 110 includes a first portion disposed opposite to the main body surface 1101a and a second portion disposed opposite to the transition surface 1101b. A support plate 121 is disposed on the first portion. A first direction is a direction that extends obliquely upward away from the main body surface 1101a, and a second direction is perpendicular to the first direction. One end of the support plate 121 extends to the end of the lower end surface of the writing pad 110 along the first direction and away from the user, and the other end of the support plate 121 extends to the junction near the first portion and the second portion.

[0144] The first part can be regarded as the lower end face of the main body 111 shown in the foregoing embodiments, and the second part can be regarded as the lower end face of the support part 112 shown in the foregoing embodiments. The other end of the support plate 121 extends to the junction near the first part and the second part, that is, the support member 120 is supported on the main body 111 of the writing board 110, and the support part 112 is not supported by the support member 120.

[0145] Since the main stress point of the writing tablet 110 is in the main body 111, supporting the main body 111 with the support member 120 helps to improve the overall stability of the main body 111, thereby improving the situation of shaking or deformation during use.

[0146] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 At least two of the support plate 121, connecting plate 122 and writing board 110 are integrally formed structures; or, at least two of the support plate 121, connecting plate 122 and writing board 110 are detachably connected.

[0147] For example, the support plate 121 and the connecting plate 122 can be a single-piece molded structure, or the connecting plate 122 and the writing board 110 can be a single-piece molded structure, or all three—the support plate 121, the connecting plate 122, and the writing board 110—can be a single-piece molded structure. The phrase "at least two of the support plate 121, the connecting plate 122, and the writing board 110 can be detachably connected" can be understood with reference to the implementation of the single-piece molded structure, and will not be elaborated further here. The detachable connection methods include plug-in connection, snap-fit ​​connection, bolt connection, etc., and are not specifically limited here.

[0148] By configuring at least two of the support plate 121, connecting plate 122, and writing board 110 into a single molded structure, it is not only easy to manufacture but also possesses certain mechanical properties. By making at least two of the support plate 121, connecting plate 122, and writing board 110 detachably connected, it is easy to store and replace the corresponding parts, providing a certain degree of flexibility and maintainability.

[0149] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The three-dimensional posture corrector 100 with wrist support function also includes an inclined support 130 located on the back of the writing board 110. The inclined support 130 connects two support plates 121.

[0150] Understandable, Figure 1 and Figure 3 From the perspective shown, a portion of the inclined support 130 can be seen through the openwork structure Q. Figure 2 and Figure 4 The tilted support 130 is not shown from the perspective illustrated.

[0151] Thus, by providing the inclined support 130, the two support plates 121 are connected via the inclined support 130, thereby further enhancing the support stability of the support member 120. Furthermore, in some embodiments, the inclined support 130 may or may not be connected to the lower end face of the writing tablet 110; no specific limitation is made here. When the inclined support 130 is connected to the lower end face of the writing tablet 110, the inclined support 130 can also be supported on the placement structure, thereby further enhancing the overall structural stability.

[0152] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The three-dimensional posture corrector 100 with wrist support function also includes a connecting part 140. The connecting part 140 is located on the side of the transition surface 1101b opposite to the main body surface 1101a.

[0153] For example, the junction of the connecting portion 140 and the transition surface 1101b is curved, and one end of the connecting portion 140 is connected to the transition surface 1101b, while the other end of the connecting portion 140 extends downward at an angle. Of course, the other end of the connecting portion 140 may also extend downward vertically, and no specific limitation is made here.

[0154] Conventional writing tablets rest directly on the surface of a desk, with a friction pad underneath to stabilize the tablet and facilitate writing or reading. However, due to user posture and writing habits, there is a risk that the user might move the tablet to a more comfortable position, affecting the posture correction function of the three-dimensional posture corrector. Therefore, this embodiment of the application includes a connecting portion 140 on the transition surface 1101b facing the user. This connecting portion 140 overlaps the edge of the desk, thereby positioning the three-dimensional posture corrector to facilitate posture correction for the user.

[0155] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The first direction is the direction that extends upwards at an angle away from the main surface 1101a, and the second direction is perpendicular to the first direction. The writing board 110, the transition surface 1101b, and the connecting part 140 form an arc-shaped surface along the first direction. That is, the transition surface 1101b and the connecting part 140 can be smoothly connected at the junction.

[0156] Thus, by making the writing pad 110, the transition surface 1101b, and the connecting part 140 form an arc-shaped surface along the first direction, the overall structure is made smoother. Even with the connecting part 140 provided, the transition surface 1101b is still easy for the user to use.

[0157] Of course, in conjunction with the situations illustrated in the foregoing embodiments, when the main surface 1101a, transition surface 1101b, and connecting portion 140 in this application form an arcuate surface along the first direction, the lowest point of the arcuate surface can be located on the transition surface 1101b. This prevents books, pens, etc., on the writing pad 110 from rolling directly off the main surface 1101a of the writing pad 110. Simultaneously, the arcuate surface can also be used to directly place various stationery items for easy access.

[0158] Therefore, the three-dimensional posture corrector 100 with wrist support function in this embodiment of the application, by setting a connecting part 140, is attached to the edge of the desk to achieve relative fixation between the three-dimensional posture corrector and the desk, so as to facilitate the posture correction of the user by the three-dimensional posture corrector. At the same time, the main body surface 1101a, the transition surface 1101b and the connecting part 140 form an arc-shaped curved surface structure to facilitate the placement of books, pens and other items on the three-dimensional posture corrector, making it convenient to access various stationery items.

[0159] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The three-dimensional posture corrector 100 with wrist support function also includes a corrector 150. The corrector 150 is disposed on the side of the transition surface 1101b opposite to the main body surface 1101a; or, the three-dimensional posture corrector 100 with wrist support function also includes a connecting part 140, which is disposed on the side of the transition surface 1101b opposite to the main body surface 1101a, and the corrector 150 is disposed on the connecting part 140.

[0160] The orthotics 150 is a functional component that uses physical limits to help users maintain a more correct body posture.

[0161] Thus, by setting the corrector 150, users can write or read with a more correct body posture. When the corrector 150 is located in the connecting part 140, on the one hand, the connecting part 140 cooperates with the edge of the table to limit the placement of the posture corrector on the table; on the other hand, by placing the corrector 150 in the connecting part 140, there is no need to provide an additional mounting structure for the corrector 150, thereby improving the utilization rate of the structure of the connecting part 140.

[0162] For example, in this embodiment of the application, the connecting portion 140 has a mounting portion protruding from one end away from the transition surface 1101b, and the mounting portion is provided with a mounting groove, in which the corrector 150 is embedded. This facilitates the installation of the corrector 150. Of course, the corrector 150 can also have other installation methods, which are not specifically limited here.

[0163] It should be noted that the connecting part 140 in this embodiment is used to attach to the edge surface of the desk and has a low overall thickness. Therefore, by providing a protruding mounting part to accommodate the corrector 150, the overall manufacturing cost of the three-dimensional posture corrector 100 with wrist support function can be reduced.

[0164] For example, there is a transitional arc-shaped surface between the mounting part and the connecting part 140. After the corrector 150 limits the user's sitting posture, the user's arms can be placed on the surface of the writing board 110 through both sides of the corrector 150. The transitional arc-shaped surface between the mounting part and the connecting part 140 facilitates the placement of the elbow, and thus facilitates the resting of the wrist on the transitional surface 1101b.

[0165] For example, in this embodiment, the corrector 150 is rotatably mounted in the mounting slot. As mentioned above, when the three-dimensional posture corrector 100 with wrist support function does not require the corrector 150, the corrector 150 can be configured to be rotatable, with the mounting portion protruding from the edge of the desk. When the corrector 150 rotates vertically, it can be retracted under the desk surface to achieve concealed storage of the corrector 150.

[0166] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing board 110 has a receiving groove 1102 on its upper surface.

[0167] For example, the receiving groove 1102 is located on the side of the main body surface 1101a away from the transition surface, and the receiving groove 1102 extends along the second direction. The receiving groove 1102 is mainly used to place electronic devices such as mobile phones, tablets, and learning machines.

[0168] Thus, by setting up the receiving slot 1102, paperless reading can be achieved.

[0169] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 3 and in conjunction with reference Figure 5 , Figure 5 This is a schematic diagram of the overall structure of the reading holder 160 in some embodiments of this application. The three-dimensional posture corrector 100 with wrist support function also includes the reading holder 160. The reading holder 160 is located on the upward tilted side of the writing tablet 110. That is, the upward tilted side of the writing tablet 110 can be understood as the side where the main body 111 of the writing tablet 110 is away from the support 112.

[0170] It is understandable that the tilt angle of the writing tablet is limited to facilitate writing, and when the writing tablet is used as a reading tablet, the user still needs to look down to read. Therefore, this embodiment of the application improves the user's reading posture by setting a reading rack 160 on the tilted upward side of the writing tablet 110 and placing books on the reading rack 160.

[0171] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 3 and Figure 5 The reading stand 160 and the writing board 110 are detachably connected.

[0172] Because the overall height of the reading stand 160 is relatively high, it will obstruct the user's view when not in use, making it inconvenient for the user to observe the blackboard, etc. Therefore, the reading stand 160 and the writing board 110 are designed to be detachable to facilitate the assembly and disassembly of the reading stand 160.

[0173] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 3 and Figure 5 The reading stand 160 includes an embedding part 161, and the writing pad 110 is provided with an embedding groove 1103. The embedding part 161 is removably embedded in the embedding groove 1103.

[0174] For example, in conjunction with reference Figure 2 , Figure 4 and Figure 5 The reading holder 160 in this embodiment further includes an abutment portion 162, a support plate 163, and a holder body 164. The support plate 163 is flush with the writing board 110. An embedding portion 161 is provided below the support plate 163, and an abutment portion 162 is arranged side by side below the embedding portion 161. The abutment portion 162 and the embedding portion 161 form a stepped platform along the inclined direction of the writing board 110. An embedding groove 1103 is provided at the end face where the writing board 110 and the support plate 121 meet. The embedding portion 161 is embedded in the embedding groove 1103. One end of the abutment portion 162 along the first direction is attached to the lower end face of the writing board 110, and the other end of the abutment portion 162 along the first direction abuts against the upper end face of the support plate 121. In some embodiments, the present application provides a corresponding recessed groove 1103 on the reading holder 160. When the embedded part 161 below the support plate 163 falls into the embedded groove 1103, one end of the abutment part 162 supports and abuts against the upper surface of the support plate 121 as a fulcrum, and the other end rests on the lower surface of the writing board 110. At the same time, the holder body 164 and the support plate 163 rest on the upper surface (i.e., the main body surface) of the writing board 110. The holder body 164 and the abutment part 162 together form a rocker arm structure, thereby achieving stable installation of the reading holder 160 on the writing board 110. Furthermore, when the reading holder 160 needs to be disassembled, the embedded part 161 can simply be pulled out along the arrangement direction of the writing board 110.

[0175] Thus, by using an embedded method to install the reading holder 160 onto the writing board 110, it is not only easy to assemble and disassemble, but also to achieve a more stable installation structure.

[0176] Therefore, by setting the corrector 150 and reading stand 160 shown in some of the above embodiments, with the corrector 150 and reading stand 160 located at both ends of the writing board 110 along the first direction, the three-dimensional posture corrector 100 with wrist support function provided in this application embodiment constitutes an integrated structure with corrector 150, writing board 110 and reading stand 160, which can realize a three-dimensional integrated structure that limits sitting posture, facilitates writing and reading.

[0177] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
