Description

Technical Field

[0001] This utility model belongs to the field of office furniture, specifically relating to a rotating connection structure, a support unit, and a folding workbench. Background Technology

[0002] According to data from Shangpu Consulting Group, the size of my country's office furniture market reached 2.05 trillion yuan in 2022. From 2018 to 2022, the size of my country's office furniture market showed a steady upward trend with an average annual compound growth rate of 6.2%, of which the demand for desks is an important component.

[0003] Research shows that the comfort and rational design of office desks, particularly a comfortable working environment, are crucial for employees. Specifically, the height of the desk's support surface should be suitable for the human body to promote healthy work. Otherwise, an unsuitable desk, or having employees maintain a fixed posture for extended periods, will subject their physiological structures to unreasonable localized stress for prolonged periods, negatively impacting their health in ways such as cervical spondylosis, muscle strain, and varicose veins. Even for the same individual, it's essential to frequently change postures during extended work sessions to alleviate prolonged localized stress on the physiological structure.

[0004] In addition to the above, another aspect that cannot be ignored is that users nowadays have increasingly higher requirements for the diversification of office and study scenarios. For example, in addition to the traditional "sitting office", users also hope to "stand office", "semi-lying office", etc. In addition to the traditional "placement on the ground", they also hope to "place on the body" and "place on the bed" in the office space.

[0005] To meet this demand, desks with adjustable load-bearing surface height have appeared on the market, including desks that can adjust the load-bearing surface height by adjusting the support angle of the support rod, desks that can adjust the load-bearing surface height by telescopic support rod, and desks that can be placed on a bed.

[0006] However, with the continuous development of the economy, people are increasingly pursuing product personalization and experiential enjoyment. The above adjustments can only achieve physical functionality and cannot adequately satisfy product personalization and experiential enjoyment. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a folding worktable based on a support unit and a rotating connection structure, which can increase the user experience and provide multiple support states to meet the personalized needs of products.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A rotary connection structure is characterized by comprising: two structural entities, each having a structural connecting groove, a structural clearance surface, and a structural mating surface. The structural connecting groove passes through the structural mating surface, and the structural clearance surface is located near the structural connecting groove, with the clearance surface and the structural mating surface being adjacent and continuous. A rotary linkage rod is rotatably disposed at both ends within the structural connecting groove. When the rotary linkage rod rotates, one structural entity rotates relative to the other structural entity and passes through the structural clearance surface during rotation, thereby achieving mating fit between the two structural mating surfaces.

[0010] Preferably, the present invention further includes a hinged pivot rod, which passes through the structural connecting groove and through the rotating linkage rod, thereby realizing the hinged setting of the rotating linkage rod on the structural entity.

[0011] Furthermore, the structural entity has a regular prism profile and two adjacent structural mating surfaces. The structural connecting groove is formed on the two structural mating surfaces, and the two adjacent planes are transitioned by an arc surface, which is the structural avoidance surface.

[0012] Furthermore, the hinged pivot rod is located near the structural clearance surface, and the rotating linkage rod is rotatably set relative to the hinged pivot rod. When the rotating linkage rod rotates 90° within the structural connection groove, one structural entity rotates relative to another structural entity, thereby achieving a "stepped" overlap between one structural contact surface of one structural entity and the structural contact surface of another structural entity. When the rotating linkage rod continues to rotate 90°, one structural entity rotates relative to the hinged pivot rod, thereby allowing the structural entity to rotate 90° through the structural clearance surface on the structural contact surface of another structural entity, thus achieving a "straight rod" corresponding splicing between the other structural contact surfaces of one structural entity and the structural contact surfaces of another structural entity.

[0013] A support unit, based on the above-described rotary connection structure, is characterized in that it comprises at least two sequentially adjacent structural entities, and the two adjacent structural entities constitute a rotary connection structure.

[0014] A folding workbench, based on the above-mentioned rotary connection structure, is characterized in that it includes: a platform body having a platform bearing surface, and a support unit, which is the above-mentioned support unit, disposed at the edge of the platform body. When the angle between the rotating linkage rod and the plane containing the platform bearing surface is 0, the folding workbench has an initial support state; otherwise, the folding workbench has multiple other support states.

[0015] Preferably, the platform body has a recessed portion, and when the folding workbench is in the initial supported state, the support unit is embedded inside the recessed portion.

[0016] Furthermore, this utility model also includes a movable support plate, which can be movably disposed on the surface of the platform body. When the folding workbench is in other support states, the support unit is inclined or extends in a straight line in a direction perpendicular to the platform support surface, and the two movable support plates cover the recessed part by moving in opposite directions.

[0017] Furthermore, the structural entity is a rod with a rectangular cross-section and has multiple structural connection grooves evenly distributed along the extension direction. Thus, the corresponding structural entity has multiple rotating linkage rods, and the gaps between the multiple structural connection grooves and the corresponding rotating linkage rods form multiple parallel structural joints on the platform bearing surface.

[0018] Furthermore, this utility model also includes an angle bracket, which is disposed between the movable bearing plate and the platform body for tilting support of the load. The angle bracket has two foldable sheet structures in the shape of a "human". The angle bracket is positioned by embedding the ends of the two sheets into different structural seams, thereby changing the tilting support angle of the load relative to the surface of the platform body.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Because the rotary connection structure of this utility model includes two structural entities and a rotary linkage rod, the structural entities have a structural connecting groove, a structural clearance surface, and a structural contact surface. The structural connecting groove passes through the structural contact surface, and the structural clearance surface is located near the structural connecting groove. The structural clearance surface and the structural contact surface are adjacent and continuous, and both ends are rotatably set in the structural connecting groove. When the rotary linkage rod rotates, one structural entity rotates relative to the other structural entity and passes through the structural clearance surface during rotation, thereby achieving the contact fit between the two structural contact surfaces. When applied to an office desk, multiple rotary connection mechanisms can be combined to enable the desk to have multiple deformable postures, which can meet the personalization of the product. Furthermore, through the process of changing the posture, the user of the desk can gain a sense of pleasure from the practice of planning and designing the posture of the desk. Therefore, this utility model can increase the pleasure of the user experience and provide multiple support states to meet the personalized needs of the product.

[0021] 2. Because the hinged pivot rod of this utility model is located near the structural clearance surface, the rotating linkage rod is rotatably configured relative to the hinged pivot rod. When the rotating linkage rod rotates 90° within the structural connection groove, one structural entity rotates relative to another structural entity, thereby achieving a "stepped" overlap between one structural contact surface of one structural entity and the structural contact surface of another structural entity. When the rotating linkage rod continues to rotate 90°, one structural entity rotates relative to the hinged pivot rod, thus allowing the structural entity to rotate 90° through the structural clearance surface on the structural contact surface of another structural entity, thereby achieving a... The two structural mating surfaces of the two structural entities are connected in a "straight rod" shape. Therefore, this utility model achieves three stable postures during use through two structural mating surfaces: initially, the two structural mating surfaces are completely mated; when the hinged rotating rod rotates 90°, the two structural mating surfaces overlap and fit together; when the hinged rotating rod continues to rotate 90°, the two structural mating surfaces are completely mated. When used in combination, the multiple rotating connection structures allow the whole to have more deformation postures, further increasing the enjoyment of the experience and meeting the personalized needs of the product.

[0022] 3. Because the support unit of this utility model includes at least two sequentially adjacent structural entities, and the two adjacent structural entities constitute a rotary connection structure, this utility model can achieve more morphological changes through the coupled use of multiple rotary connection structures.

[0023] 4. Because the folding workbench of this utility model includes a platform body and a support unit, and the platform body has a platform bearing surface, when the angle between the rotating linkage rod and the plane where the platform bearing surface is located is 0, the folding workbench has an initial support state; otherwise, the folding workbench has other support states. Therefore, the folding workbench of this utility model can increase the enjoyment of the experience and provide multiple support states to meet the personalized needs of the product.

[0024] 5. Because the platform body of this utility model has a recessed part, when the folding workbench is in the initial support state, the support unit is embedded in the interior of the recessed part. Therefore, this utility model achieves a compact structure and regular overall shape of the office table through the recessed part, making it easier to store and place.

[0025] 6. Because this utility model also includes a movable support plate, which can be movably disposed on the surface of the platform body, when the folding workbench is in other support states, the support unit is inclined or extends in a straight line in the direction perpendicular to the platform support surface. The two movable support plates cover the recessed part by moving in opposite directions. Therefore, this utility model can further increase or decrease the area of ​​the platform support surface through the movable support plate to flexibly meet actual needs.

[0026] 7. Because the structural entity of this utility model is a rod with a rectangular cross-section and has multiple structural connecting grooves evenly distributed along the extension direction, the corresponding structural entity has multiple rotating linkage rods. The gaps between the multiple structural connecting grooves and the corresponding rotating linkage rods form multiple parallel structural caulking joints on the platform bearing surface. Therefore, when the support legs of the load on the platform bearing surface are plate-shaped legs, the plate-shaped legs can be embedded in the structural caulking joints of this utility model for positioning, thereby enabling a more stable bearing on the load.

[0027] 8. Because this utility model also includes an angle bracket, which is set between the movable support plate and the platform body, for tilting support of the load. The angle bracket has two foldable sheet structures in the shape of a "human". The angle bracket is positioned by embedding the two sheet ends into different structural seams, thereby changing the tilting support angle of the load relative to the surface of the platform body. Therefore, this utility model can provide different tilt angle support for the load on the platform bearing surface through its built-in angle bracket, and the angle bracket can be hidden and stored by the movable support plate.

[0038] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate the rotary connection structure, support unit and folding worktable of this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0039] like Figure 1 and Figure 2 As shown, the rotary connection structure 10 in this embodiment includes a structural entity 11, a rotary linkage rod 12, and a hinged pivot rod 13.

[0040] The structural entity 11 has a regular prism outline and there are two of them. The structural entity 11 has a structural connecting groove 11a, a structural clearance surface 11b and a structural fitting surface 11c. Specifically, the structural entity 11 has a regular square prism outline.

[0041] The structural mating surfaces 11c are planar and there are two of them. The structural avoidance surfaces 11b are curved surfaces. The two structural mating surfaces 11c are adjacent and transition through the structural avoidance surfaces 11b. The structural connecting groove 11a is formed on the two structural mating surfaces 11c. The structural connecting groove 11a passes through the structural mating surfaces 11c. The structural avoidance surfaces 11b are located near the structural connecting groove 11a and are adjacent and continuous with the structural mating surfaces 11c. In this embodiment, the structural avoidance surfaces 11b make the edges of the cube outline rounded. The volume of the structural connecting groove 11a has a rectangular outline, and the structural entity 11 exactly bisects the structural connecting groove 11a.

[0042] Specifically, the number of structural connecting grooves 11a is one or two. When the number of structural connecting grooves 11a is two, the two structural connecting grooves 11a are distributed in a straight line on one side of the structural entity 11, or distributed in an oblique line on opposite corners of the structural entity 11.

[0043] The two ends of the rotating linkage rod 12 are rotatably disposed in the structural connection groove 11a. The hinged rotating shaft rod 13 passes through the inside of the structural connection groove 11a and through the rotating linkage rod 12, thereby realizing the hinged arrangement of the rotating linkage rod 12 inside the structural connection groove 11a on the structural entity. Specifically, the extension axis of the rotating linkage rod 12 is parallel to the structural contact surface 11c. The two ends of the rotating linkage rod 12 pass through the structural connection groove 11a of the two structural entities 11, and each end of the rotating linkage rod 12 has a through hole for the hinged rotating shaft rod 13 to pass through (not shown in the figure).

[0044] The hinged pivot rod 13 is located near the structural clearance surface 11b. The rotating linkage rod 12 is rotatably set relative to the hinged pivot rod 13. When the rotating linkage rod 12 rotates, one structural entity 11 rotates relative to another structural entity 11 and passes through the structural clearance surface 11b during the rotation, thereby achieving the mating fit of the two structural mating surfaces 11c.

[0045] like Figure 3 and Figure 4 As shown, when the rotating linkage rod rotates 90° within the structural connection groove, one structural entity rotates relative to another structural entity, thereby achieving a "stepped" overlap between one structural contact surface of one structural entity and the structural contact surface of another structural entity. When the rotating linkage rod continues to rotate 90°, one structural entity rotates relative to the hinged pivot rod, thereby allowing the structural entity to rotate 90° on the structural contact surface of another structural entity through the structural clearance surface, thus achieving a "straight rod" corresponding splicing between the other structural contact surfaces of one structural entity and the structural contact surfaces of another structural entity.

[0046] like Figure 5 As shown, the support unit 10A is based on the above-mentioned rotary connection structure 10 and includes at least two adjacent structural entities 11, and the two adjacent structural entities 11 constitute the rotary connection structure 10. Specifically, in practical applications, the dimensional parameters of the regular square prism outline of the structural entity 11 can be changed as needed, such as the length, width and aspect ratio of the structural entity 11.

[0047] like Figures 6 to 9 As shown, the folding workbench 100 includes a platform body 20, a support unit 10A, a movable bearing plate 30, and an inclined bracket 40.

[0048] The platform body 20 has a platform bearing surface (not shown in the figure) for serving as a bearing plane, and the support unit 10A is provided at the edge of the platform body 20. Specifically, the platform body 20 is flat.

[0049] The platform body 20 also has a recessed portion 20a. In this embodiment, there are two recessed portions 20a, which are rectangular recessed structures formed on opposite sides of the platform body 20. The platform body 20 forms an "I" shape through the recessed portions 20a.

[0050] There are two support units 10A, and the corresponding structural entity 11 is a rectangular prism rod with a rectangular cross section. The structural entity 11 has multiple structural connecting grooves 11a evenly distributed along the extension direction, so the corresponding structural entity 11 has multiple rotating linkage rods 12.

[0051] Two support units 10A are respectively embedded inside the recess 20a. Specifically, multiple structural entities 11 of the support unit 10A are sequentially hinged from the inside of the recess 20a outwards. Each structural entity 11 of the support unit 10A has two lengths. The shorter structural entity 11 is located inside the recess 20a and its length corresponds to the side length of the recess 20a. The longer structural entity 11 is located outside the recess 20a and its length corresponds to the side length of the platform body 20 at the opening of the recess 20a, thus forming a regular plate shape. The length support unit 10A forms a support structure for the platform body 20 through posture deformation. Therefore, by setting different posture deformations of the support unit 10A, not only can different shapes of folding worktables 100 be obtained, but also different support heights can be obtained for the platform bearing surface.

[0052] The gaps between the multiple structural connecting grooves 11a and the corresponding rotating linkage rods 12 form multiple parallel structural caulking joints 20b on the platform bearing surface.

[0053] When the angle between all the rotating linkages 12 of the support unit 10A and the plane on which the platform bearing surface is located is 0, the folding worktable 100 has an initial support state; otherwise, the folding worktable 100 has multiple other support states. When the folding worktable 100 is in the initial support state, the support unit 10A is embedded in the recess 20a. When the folding worktable 100 is in other support states, the support unit 10A is inclined or extends in a straight line in a direction perpendicular to the platform bearing surface. In this embodiment, when the folding worktable 100 has the initial support state, the platform body 20 and the support unit 10A are generally rectangular flat plates. When the folding worktable 100 has other support states, the platform body 20 and the support unit 10A are generally stool-shaped with an "I"-shaped platform support surface and two supports. The multiple other support states correspond to multiple different support postures.

[0054] There are two movable support plates 30, which are movably disposed on the surface of the platform body 20. The two movable support plates 30 cover the recessed portion 20a by moving in opposite directions. When the movable support plates 30 cover the recessed portion 20a by moving in opposite directions, the caulking joint 20b formed on the platform support surface structure is exposed outward.

[0055] In this embodiment, recessed tracks (not shown in the figures) are provided on two opposite edges of the surface of the platform body 20, so that the movable support plate 30 can be inserted into the recessed tracks and become movable.

[0056] An inclined bracket 40 is disposed between the movable support plate 30 and the platform body 20 to provide inclined support for the load. The inclined bracket 40 has two foldable sheet structures in the shape of a "human". Specifically, when the movable support plate 30 does not cover the recess 20a, the inclined bracket 40 is folded and hidden between the movable support plate 30 and the platform body 20; when the movable support plate 30 covers the recess 20a, the inclined bracket 40 is exposed.

[0057] The tilt bracket 40 is positioned by embedding the two ends of the sheet into different structural caulking joints 20b, thereby changing the tilt support angle of the load relative to the surface of the platform body 20. Specifically, the tilt bracket 40 includes a long support piece 41 and a short support piece 42, which are respectively embedded in different structural caulking joints 20b. The larger the distance between the structural caulking joints 20b into which the long support piece 41 and the short support piece 42 are embedded, the smaller the tilt support angle.

[0058] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
