Description

Technical Field

[0001] This application belongs to the field of posture correction technology, specifically relating to a three-dimensional posture corrector with wrist support function. Background Technology

[0002] A reading and writing desk is an auxiliary tool placed on a desktop to facilitate reading and writing. It usually has a support plate structure with a certain 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. Utility Model Content

[0078] 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 2 This 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 tablet 110 and a support member 120. The writing tablet 110 has a writing surface 1101 arranged obliquely upward. The support member 120 is disposed 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 is arranged horizontally. One end of the writing tablet 110 extends obliquely upward, and the other end of the writing tablet 110 extends along a first direction and a second direction, forming a transition surface 1101a in the first direction and the second direction. The writing tablet 110 includes a support structure 111 formed by the extension of the transition surface 1101a, and at least a portion of the lower end surface of the support structure 111 is located on the same horizontal plane as the lower end surface of the support member 120.

[0079] The support member 120 is mainly used to support the writing board 110 so that the writing board 110 is arranged at an angle.

[0080] The writing surface 1101 can be viewed as the upward-facing upper surface of the writing pad 110, that is, the surface facing the user. Here, "facing the user" refers to the surface that directly contacts the user's body or actions during use. In other words, the surface facing the user is not necessarily the surface directly opposite the user. The writing surface 1101 includes a transition surface 1101a and a main body portion (not shown in the figure) arranged at an upward angle. The transition surface 1101a is the portion of the writing surface 1101 that connects to the main body portion of the writing surface 1101. The transition surface 1101a can be used to rest the wrist and elbow, or to rest either the wrist or the elbow.

[0081] It should be noted that the first direction and the second direction are used to characterize the extension state of the transition surface 1101a, reflecting that the transition surface 1101a has a certain length and width, and do not impose restrictions on the shape changes of the transition surface 1101a. The first direction and the second direction are two different directions, 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.

[0082] The transition surface 1101a extends outward relative to the writing pad 110. This outward extension of the transition surface 1101a can be understood as forming the supporting structure 111, which constitutes part of the writing pad 110. The other part of the writing pad 110 can be considered as its main body (not shown in the figure), meaning the upward-sloping portion corresponds to the other part of the writing pad 110 (i.e., the main body). The upward-facing surface of the supporting structure 111 is the transition surface 1101a.

[0083] The horizontal plane can be understood as the placement plane of the structure, for example, the placement structure can be a desk. At least a portion of the lower end face of the supporting structure 111 is located on the same horizontal plane as the lower end face of the support member 120. That is, both the supporting structure 111 and the support member 120 are in contact with the placement plane. The supporting structure 111 and the support member 120 can jointly provide support, thereby improving the support stability during use.

[0084] Thus, the transition surface 1101a extends outward to form a support structure 111, which can be used to rest the wrist and / or elbow to improve the wrist or elbow from being suspended or pressed against the side of the writing board 110, thereby improving the comfort of using the writing board 110 and improving the effectiveness of posture correction.

[0085] It should be noted that the transition surface 1101a 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, however, the design of the transition surface 1101a provides sufficient support for the user's arm, effectively improving the stiffness caused by incorrect wrist movement due to unsupported wrists, and enhancing the comfort of using the posture corrector.

[0086] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The transition surface 1101a includes a smooth transition surface. The area in the writing surface 1101 that is arranged at an upward angle is smoothly connected to the transition surface 1101a. It can be understood that the area in the writing surface 1101 that is arranged at an upward angle is the main part that is arranged at an upward angle as mentioned in some of the foregoing embodiments.

[0087] 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 limitation is made here. A smooth connection means that the tangent vector direction of the area arranged obliquely upward in the writing surface 1101 and the transition surface 1101a at the intersection tends to be consistent, without sharp turns.

[0088] By setting a smooth transition surface, user comfort can be improved while structural durability is enhanced. Since "the upwardly angled area of ​​the writing surface 1101 is smoothly connected to the transition surface 1101a," and at least a portion of the supporting structure 111 is on the same horizontal plane as the lower end face of the support member 120, the user's wrist and / or elbow can receive more stable support while allowing the item to be placed at a certain angle. It is understood that if the connection between "the upwardly angled area of ​​the writing surface 1101 and the transition surface 1101a" were a plane-to-plane connection, it would either form a significant angle or simply be an angled plane. In this case, the area would inevitably fail to provide adequate support for the user's wrist or hand, or the angle of force application would be incorrect. Therefore, the structure provided in this embodiment helps improve the correctness of the user's posture and enhances user comfort.

[0089] It should be noted that "the area arranged at an upward angle in the writing surface 1101 is smoothly connected to the transition surface 1101a" can mean that the surface on the transition surface 1101a connecting to the intersection line of the transition surface 1101a and the "area arranged at an upward angle in the writing surface 1101" is a smooth transition surface. Furthermore, the surface on the "area arranged at an upward angle in the writing surface 1101" connecting to the intersection line can also be a smooth transition surface. As long as a smooth connection can be achieved between the transition surface 1101a and the "area arranged at an upward angle in the writing surface 1101" at the intersection line, no specific restrictions are imposed here.

[0090] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The transition surface 1101a has a curved structure; and / or, the surface parallel to the direction from the side of the writing surface 1101 away from the user to the side of the writing surface 1101 facing the user, and intersecting with the transition surface 1101a, is a reference surface. The intersection line of the reference surface and the transition surface 1101a is a smooth curve.

[0091] A smooth curve is one without sharp inflection points and without abrupt changes in the direction of the tangent.

[0092] Because the transition surface 1101a has a curved structure, it is beneficial to improve user comfort and ease of use. Since the intersection of the transition surface 1101a and the reference surface is a smooth curve, the transition surface 1101a extends smoothly from the side away from the user to the side facing the user. Therefore, the transition surface 1101a can be roughly regarded as a smooth curve swept along a direction perpendicular to the reference surface. This not only improves the overall integrity and consistency of the product, but also allows for a smooth transition between the desk and the writing tablet 110, or between the writing tablet 110 itself, regardless of whether the user moves their wrist and / or elbow from the first or second direction, without any sense of obstruction. This further enhances user comfort and ease of use, thereby improving posture correction.

[0093] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The lowest point in the writing surface 1101 is located on the transition surface 1101a, and the side of the transition surface 1101a that is away from the end of the writing board 110 that is inclined upward is located above the lowest point.

[0094] This results in the transition surface 1101a having a generally recessed portion. In this way, books, pens, and other items on the writing board 110 will not roll directly down the writing surface 1101 of the writing board 110, but will slide down to the area of ​​the transition surface 1101a under the influence of gravity. At the same time, various stationery items can be placed directly on the transition surface 1101a for easy access.

[0095] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The first direction is the direction that extends obliquely upward away from the writing surface 1101, and the second direction is perpendicular to the first direction; the transition surface 1101a protrudes from the area obliquely upward arranged in the writing surface 1101 along both sides of the second direction.

[0096] Because the transition surface 1101a protrudes from the "area arranged obliquely upward in the writing surface 1101" on both sides along the second direction, the writing surface 1101 of the writing tablet 110 is generally opened towards the side set by the user, thereby making the extension range of the transition surface 1101a in the second direction larger, thus providing the user with a wider range of use and further providing more support for the user's wrist and / or elbow.

[0097] It should be noted that, in this embodiment of the application, the shape of the protrusions on both sides of the transition surface 1101a along the second direction relative to the "area arranged obliquely upward in the writing surface 1101" 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. Exemplarily, the transition surface 1101a and the "area arranged obliquely upward in the writing surface 1101" can be smoothly connected on the same side along the second direction.

[0098] For example, with Figure 2 and Figure 4 For example, along a direction that extends upwards from the "area arranged upwards in the writing surface 1101", the transition surface 1101a, on one side of the second direction, presents a shape that first protrudes and then retracts in the opposite direction to the "area arranged upwards in the writing surface 1101". It can be understood that even when it retracts in the opposite direction to the protrusion, the transition surface 1101a, on one side of the second direction, still protrudes relative to the "area arranged upwards in the writing surface 1101".

[0099] 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.

[0100] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 One end of the writing tablet 110 with a transition surface 1101a is located on the same horizontal plane as the lower end surface of the support member 120. The end of the writing tablet 110 that connects with the horizontal plane extends along a first direction and a second direction, and forms a transition surface 1101a in the first direction and the second direction.

[0101] In the above-described embodiments of this application, a transition surface 1101a is provided on the side of the inclined writing board 110 near the horizontal plane. The transition surface 1101a extends outward to form a support structure 111. On the one hand, it can be used to rest the wrist and / or elbow to improve the user's wrist and / or elbow from being suspended or pressed on the side of the writing board 110, thereby improving the user's comfort. On the other hand, since the transition surface 1101a, formed by the extension of the "end where the writing board 110 meets the horizontal plane", completes the transition between the writing board 110 and the desk, the user can reduce the feeling of obstruction when transitioning between the desk and the writing board 110 from either the first or second direction.

[0102] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 Along the direction away from the horizontal center of the writing board 110, the maximum thickness of the supporting structure 111 tends to decrease.

[0103] The cross-section of the supporting structure 111 perpendicular to the "direction away from the horizontal center of the writing board 110" can be of equal thickness or unequal thickness. When the cross-section is of equal thickness, its maximum thickness is the thickness of that cross-section. When the cross-section is of unequal thickness, its maximum thickness is the thickness of the largest possible thickness among the thicknesses of that cross-section.

[0104] This results in a smaller maximum thickness for the portion of the support structure 111 closer to the user. When the support structure 111 is subjected to pressure or other forces from the user, the stress distribution gradually decreases from the side away from the user to the side closer to the user, thereby improving the stress concentration in the portion closer to the user.

[0105] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The supporting structure 111 includes a supporting body 1111 and an edge portion 1112, with the edge portion 1112 located at the edge of the supporting body 1111. The end of the supporting structure 111 facing away from the user is defined as the starting end of the supporting structure 111, and the horizontal direction pointing from the starting end to the user is defined as the reference direction. Along the reference direction, the distance between the upper and lower surfaces of the edge portion 1112 decreases.

[0106] For example, the edge portion 1112 can be formed by a one-piece molding process. For instance, the edge portion 1112 may be a structure that folds over at the edge of the body 1111.

[0107] Thus, by providing an edge portion 1112 at the edge of the supporting body 1111, not only can the bending strength of the supporting structure 111 be improved, thereby enhancing the edge's resistance to deformation, but it can also serve as a protective structure at the edge of the supporting structure 111, thereby further improving user comfort. Simultaneously, since the distance between the upper and lower surfaces of the edge portion 1112 gradually changes along the reference direction, the distance corresponding to the portion of the edge portion 1112 closer to the user is smaller. When the edge region of the transition surface 1101a is subjected to user pressure or other forces, the stress distribution gradually decreases from the side away from the user to the side closer to the user, thereby improving the stress concentration situation in the part closer to the user.

[0108] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 At least a portion of the lower end face of the edge portion 1112 is located on the same horizontal plane as the lower end face of the support member 120; and / or, the distance between the upper end face and the lower end face of the edge portion 1112 is 1 mm to 5 mm.

[0109] At least a portion of the lower end face of the edge portion 1112 is located on the same horizontal plane as the lower end face of the support member 120. That is, both the edge portion 1112 and the support member 120 can contact the placement plane, and the edge portion 1112 can also provide support. The distance between the upper end face and the lower end face of the edge portion 1112 can be any value within the range of 1 mm to 5 mm, for example, it can be 1 mm, 2 mm, 3 mm or 5 mm, and no specific limitation is made here.

[0110] By controlling the distance between the upper end face and the lower end face of the edge portion 1112 to be 1mm to 5mm, it is not only beneficial to the transition of the transition surface 1101a, but also to the edge portion 1112 being supported more stably on the placement plane.

[0111] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 Along the direction away from the horizontal center of the writing board 110, the thickness of the supporting structure 111 formed by the extension of the transition surface 1101a gradually decreases and adheres to the horizontal surface.

[0112] In terms of overall shape, it can be roughly understood that the part of the transition surface 1101a that is closer to the user is closer to the horizontal plane. Thus, it can be roughly seen as the transition surface 1101a gradually attaching to the horizontal plane.

[0113] In this way, the transition between the writing board 110 and the desk is completed by the gradually thinning support structure 111, so that the transition surface 1101a can form a gradually transitioning surface, so that the user can further reduce the sense of obstruction when transitioning between the desk and the writing board 110 from the first direction or the second direction.

[0114] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 Along the direction away from the horizontal center of the writing board 110, the transition surface 1101a smoothly transitions to the horizontal surface.

[0115] In terms of overall shape, it can be roughly understood that the part of the transition surface 1101a that is closer to the user is closer to the horizontal plane. Thus, it can be roughly seen as the transition surface 1101a gradually attaching to the horizontal plane.

[0116] Thus, the transition between the writing board 110 and the desk is completed by the gradually thinning support structure 111, so that the transition surface 1101a can form a gradually transitioning and smooth transition surface, so that the user can further reduce the sense of obstruction when transitioning between the desk and the writing board 110 from the first direction or the second direction.

[0117] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing surface 1101 of the writing tablet 110 is arranged at an upward angle. 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 is arranged horizontally. As shown in some of the aforementioned embodiments, the support member 120 is mainly used to support the writing tablet 110 so that the writing tablet 110 is arranged at an angle.

[0118] The writing board 110 has one end extending upward at an angle, and the other end of the writing board 110 is located on the same horizontal plane as the lower end surface of the support member 120. The writing board 110 extends along a first direction and a second direction at the end that contacts the horizontal plane, and forms a transition surface 1101a in the first direction and the second direction. The transition surface 1101a gradually transitions along the direction away from the horizontal center of the writing board 110 until it is attached to the horizontal plane.

[0119] Therefore, in this embodiment, a transition surface 1101a is provided on the side of the inclined writing board 110 near the horizontal plane. The transition surface 1101a extends outward to form a support structure 111, which can be used to support the user's wrist and / or elbow to improve the user's wrist or elbow from being suspended or pressed on the side of the writing board 110, thereby improving the user's comfort. On the other hand, the transition surface 1101a, which gradually thins, completes the transition between the writing board 110 and the desk, forming a smooth curved surface. This further reduces the feeling of resistance when the user transitions between the desk and the writing board 110 from either the first or second direction, making it easier to use the three-dimensional posture corrector 100 with wrist support function.

[0120] It should be noted that, in the embodiments of this application, the supporting structure 111 formed by extending outward from the transition surface 1101a can be understood and implemented with reference to the situation illustrated in some of the foregoing embodiments, and its advantages can also be understood with reference to the situation illustrated in some of the foregoing embodiments, and will not be repeated here.

[0121] For example, in this embodiment, both the first direction and the second direction are located in the horizontal plane. The first direction can be the user's forward viewing direction (i.e., the width direction of the desk), and the second direction can be the direction of the desk edge opposite to the user (i.e., the length direction of the desk), and the first direction and the second direction are set perpendicularly. Meanwhile, the support structure 111 formed by the transition surface 1101a in this application has a certain thickness. Therefore, the transition surface 1101a gradually transitions along the horizontal center direction away from the writing board 110 to be attached to the horizontal plane, which can be seen as the support structure 111 gradually thinning and attaching to the horizontal plane. The gradual transition of the transition surface 1101a to be attached to the horizontal plane can be a smooth transition of the transition surface 1101a to the horizontal plane, until the user's wrist and / or elbow do not feel any discomfort when resting on the edge of the transition surface 1101a. For example, when the thickness at the edge of the transition surface 1101a is between 1mm and 5mm, it can be considered that the edge of the transition surface 1101a is in a state of being attached to the horizontal plane.

[0122] It should be noted that the gradually thinning transition surface 1101a mentioned above is meant to represent the transition between the writing tablet 110 and the desk, and is not a special limitation on the transition surface 1101a. The transition shape between the writing tablet 110 and the desk can be understood with reference to the above illustrations, and will not be repeated here.

[0123] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The writing board 110 has a one-piece molded structure.

[0124] Thus, by configuring the writing board 110 as a one-piece 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 ease of maintenance.

[0125] According to some embodiments of this application, the upwardly inclined area of ​​the writing pad 110 and the supporting structure 111 are detachably connected. The upwardly inclined area of ​​the writing pad 110 is also the main body of the writing pad 110; that is, the main body of the writing pad 110 and the supporting structure 111 are detachably connected. When the transition surface 1101a is detachably connected to the writing pad 110, it can be understood that the main body of the writing pad 110 and the supporting structure 111 are detachably connected.

[0126] As mentioned earlier, the transition surface 1101a can be a curved structure. When the thickness of the supporting structure 111, formed by the extension of the transition surface 1101a, gradually decreases along the direction away from the horizontal center of the writing board 110 and attaches to the horizontal surface, the writing board 110, being a relatively regular plate structure, would increase the overall manufacturing difficulty of the writing board 110 due to its integral form, potentially reducing product yield. Therefore, in this embodiment, the upwardly inclined area of ​​the writing board 110 and the supporting structure 111 are designed to be detachably connected to facilitate their production. Specifically, the upwardly inclined area of ​​the writing board 110 and the supporting structure 111 are respectively provided with protrusions and grooves at their contact surfaces to facilitate assembly and disassembly. Of course, other methods such as adhesion and screw fixing can also achieve a detachable connection between the upwardly inclined area of ​​the writing board 110 and the supporting structure 111.

[0127] 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.

[0128] 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.

[0129] It should be noted that "both the first and second directions are located in 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.

[0130] 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 that extends upwards at an angle away from the writing surface 1101, 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.

[0131] 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.

[0132] 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.

[0133] 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 writing board 110.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The first direction is a direction that extends obliquely upward from the writing surface 1101, and the second direction is perpendicular to the first direction. Support members 120 are arranged in pairs, with one support member 120 at each end of the lower end surface of the writing pad 110 along the second direction. The three-dimensional posture corrector 100 with wrist support function also includes an inclined support 130 located on the back of the writing pad 110, connecting the two support members 120.

[0138] For example, when 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, the tilting support 130 connects the two support plates 121.

[0139] 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.

[0140] Thus, by providing the inclined support 130, the two support members 120 are connected via the inclined support 130, thereby further enhancing the support stability of the support members 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 is also supported on the placement plane, thereby further enhancing the overall structural stability.

[0141] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 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. The connecting plate 122 is arranged horizontally and the support plate 121 is arranged vertically. The writing board 110, the support plate 121 and the connecting plate 122 form a triangular support structure.

[0142] The triangular support structure can be understood by referring to the illustrations in some of the aforementioned embodiments, and will not be elaborated upon here.

[0143] In this way, the writing pad 110 can be arranged more stably at an upward tilt. For example, a tilting support 130 can be arranged on the back of the writing pad 110, and a spring structure can be arranged between the writing pad 110 and the connecting plate 122 to achieve the tilted arrangement of the writing pad 110. In some embodiments, the tilting support 130 is implemented as illustrated in the aforementioned embodiments.

[0144] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 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; and / or, the first direction is the direction of the side that extends obliquely upward away from the writing surface 1101, and the second direction is perpendicular to the first direction; one end of the support plate 121 extends to the lower end surface of the writing board 110 along the first direction and away from the user, and the other end of the support plate 121 extends to the junction of the obliquely upward area in the writing board 110 and the supporting structure 111.

[0145] The area where the writing pad 110 is tilted upwards and the junction with the supporting structure 111 can be understood as the supporting structure 111 being on the side away from the user.

[0146] Thus, since the support plate 121 and the connecting plate 122 are respectively located at both ends of the writing board 110 along the second direction, the overall stability can be improved while reducing the overall weight of the three-dimensional posture corrector, reducing the manufacturing cost of the three-dimensional posture corrector, and making it convenient for users to use the three-dimensional posture corrector. Since the area in the writing board 110 that is inclined upward is the main stress point, by extending the other end of the support plate 121 to the junction near the area in the writing board 110 that is inclined upward and the supporting structure 111, the overall structural stability of the writing board 110 is improved, thereby reducing the possibility of shaking or deformation during use.

[0147] Based on some embodiments of this application, please continue to refer to Figures 1 to 4At 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.

[0148] 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.

[0149] Thus, 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.

[0150] 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 connector 140, which is located on the side of the support structure 111 facing the user.

[0151] For example, the connecting portion 140 is provided on the side of the transition surface 1101a facing the user.

[0152] A conventional writing tablet 110 rests directly on the surface of a desk, with a friction pad underneath to fix it relatively in place, facilitating writing or reading. However, due to user posture and writing habits, there is a risk that the user might move the writing tablet 110 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 1101a 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.

[0153] Based on some embodiments of this application, please continue to refer to Figures 1 to 4The connecting part 140 is curved at the junction with the transition surface 1101a; and / or, one end of the connecting part 140 is connected to the transition surface 1101a, and the other end of the connecting part 140 extends downward at an angle; and / or, the writing surface 1101, the transition surface 1101a and the connecting part 140 form an arc-shaped surface along the first direction, and the lowest point of the arc-shaped surface is located on the upper surface of the transition surface 1101a.

[0154] For example, a connecting portion 140 is provided on the side of the transition surface 1101a facing the user. The connecting portion 140 is curved at the junction with the transition surface 1101a, and one end of the connecting portion 140 is connected to the transition surface 1101a, while the other end of the connecting portion 140 extends downward at an angle.

[0155] By making the junction of the connector 140 and the transition surface 1101a curved, the comfort of the user's wrist and / or elbow when moving at the junction of the connector 140 and the transition surface 1101a can be improved.

[0156] One end of the connecting part 140 is connected to the transition surface 1101a, and the other end of the connecting part 140 extends downward at an angle, which makes it easier for the connecting part 140 to overlap the edge of the desk.

[0157] The writing surface 1101, the transition surface 1101a, and the connecting part 140 form an arc-shaped surface along the first direction. That is, an arc-shaped surface is roughly formed on the three-dimensional posture corrector in the first direction. This makes the overall structure more streamlined. Even with the connecting part 140, the transition surface 1101a is still easy for the user to use. When the lowest point of the arc-shaped surface is located on the transition surface 1101a, books, pens, etc., on the writing pad 110 will not roll directly off the writing surface 1101 of the writing pad 110. At the same time, various stationery items can also be placed directly on the arc-shaped surface for easy access.

[0158] Therefore, the three-dimensional posture corrector 100 with wrist support function in this embodiment of the application, by setting the connecting part 140 shown in the above embodiments, uses the connecting part 140 to overlap 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, by forming an arc-shaped surface along the first direction with the writing surface 1101, the transition surface 1101a and the connecting part 140, it is convenient to place books, pens, etc. on the three-dimensional posture corrector, and to facilitate the use of 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, which is located on the side of the support structure 111 facing the user.

[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.

[0162] 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 connector 140. The connector 140 is located on the side facing the user, and the corrector 150 is located on the connector 140.

[0163] 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 position 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 installation structure for the corrector 150, thereby improving the utilization rate of the structure of the connecting part 140.

[0164] 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 mounting part, which protrudes from the end of the connecting part 140 away from the supporting structure 111. The mounting part has a mounting slot, and the corrector 150 is embedded in the mounting slot. 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.

[0165] 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.

[0166] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The mounting part and the connecting part 140 have a transition arc surface; and / or, the corrector 150 is rotatably mounted in the mounting slot.

[0167] 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 the sides of the corrector 150. A transition arc surface is provided between the mounting part and the connecting part 140 to facilitate the placement of the elbow, and thus facilitate the resting of the wrist on the transition surface 1101a.

[0168] By rotatably mounting the corrector 150 into the mounting slot, when the three-dimensional posture corrector 100 with wrist support function is not in use, the corrector 150 can be configured to rotate, with the mounting part 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.

[0169] 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.

[0170] For example, the receiving slot 1102 is located on the side of the writing board 110 away from the transition surface 1101a, and the receiving slot 1102 extends along the second direction. The receiving slot 1102 is mainly used to place electronic devices such as mobile phones, tablets, and learning machines.

[0171] Thus, by setting up the receiving slot 1102, paperless reading can be achieved.

[0172] 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 The diagram below shows the overall structure of the reading stand 160 in some embodiments of this application. The three-dimensional posture corrector 100 with wrist support function also includes the reading stand 160, which is located at the inclined upward end of the writing board 110.

[0173] It is understandable that, for ease of writing, the tilt angle of the writing tablet 110 itself is limited. When the writing tablet 110 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 at the tilted upward end of the writing tablet 110 and placing books on the reading rack 160.

[0174] 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.

[0175] 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.

[0176] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 3 and Figure 5The 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.

[0177] 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, while the other end rests on the lower surface of the writing board 110. Simultaneously, the holder body 164 and the support plate 163 rest on the upper 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.

[0178] 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.

[0179] 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.

[0180] 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.
