Description

Technical Field

[0001] This utility model relates to the field of storage products, specifically to a folding storage device. Background Technology

[0002] Existing folding storage devices typically use an X-shaped rod structure to connect two shelves. Users need to press or pull the upper shelf to move it up or down, causing the device to fold or unfold. However, this X-shaped rod structure offers only one way to control the shelf's movement, making it difficult to meet the diverse usage needs of users in various scenarios. Utility Model Content

[0003] This utility model mainly addresses the shortcomings of the existing technology, specifically relating to a folding storage device that solves the problem of the limited usage of existing folding devices.

[0004] Technical solution

[0005] This utility model relates to a folding storage device, characterized in that it includes: a storage part for placing items; a fixing part for supporting the storage part; and a lifting member, the two ends of which are rotatably connected to the storage part and the fixing part, respectively. The storage part is driven to rotate around a first rotation axis or a second rotation axis, and the two ends of the lifting member rotate relative to the storage part and the fixing part, respectively, so that the storage part moves closer to or further away from the fixing part in the direction along the first rotation axis. The first rotation axis extends along the projection direction of the storage part to the fixing part and passes through the storage part. The second rotation axis is perpendicular to the first rotation axis and passes through the fixing part.

[0006] The beneficial effect is that the lifting components are rotatably connected to the storage section and the fixed section respectively, allowing the storage section to rotate around two mutually perpendicular rotation axes. Either rotation method can change the distance between the storage section and the fixed section on the first rotation axis. This allows the storage section to have two folding methods: the first folding method involves rotating and folding the storage section along the first rotation axis, in which case the sum of the storage areas of the storage section and the fixed section does not exceed the area of ​​either the storage section or the fixed section; the second folding method involves rotating and folding the storage section along the second rotation axis, in which case the sum of the areas of the storage section and the fixed section can reach up to twice the storage area of ​​either the storage section or the fixed section. This allows users to choose different folding methods according to different usage scenarios, improving the practicality of the folding storage device and meeting the diverse usage needs of users in various life scenarios.

[0007] In one optional embodiment, the lifting component includes a rod body, with universal rotating assemblies at both ends of the rod body, and the two ends of the rod body are rotatably connected to the placement part and the fixing part respectively through the universal rotating assemblies.

[0008] The advantage is that the universal rotating assembly can rotate in any direction. When the storage part is driven to rotate along the first rotating axis, the storage part can drive the rod to rotate in any direction through the universal rotating assembly, thereby improving the flexibility of the folding and storage device.

[0009] In one optional embodiment, the lifting member further includes a locking member;

[0010] The locking member is configured to cooperate with the universal rotating assembly between the rod and the storage part, and is used to lock the universal rotating assembly, restricting the relative rotation of the rod and the storage part through the universal rotating assembly, so that the relative position between the fixing part and the storage part remains fixed;

[0011] And / or, the locking member is configured to cooperate with the universal rotation assembly between the rod and the fixed part to lock the universal rotation assembly, restricting the relative rotation of the rod and the fixed part through the universal rotation assembly, so that the relative position between the fixed part and the placement part remains fixed.

[0012] The advantage is that the locking mechanism makes the storage compartment more secure and reliable when it is in the preset position.

[0013] In one optional embodiment, the universal rotating assembly includes a universal ball and a mounting part, the mounting part being provided with an arc-shaped groove, the universal ball being disposed in the arc-shaped groove and the outer wall of the universal ball being slidable relative to the inner wall of the arc-shaped groove;

[0014] The locking element is used to limit the relative sliding between the omnidirectional ball and the arc-shaped groove.

[0015] The advantage is that the combination of the omnidirectional ball and the arc-shaped groove makes the rod connected to it rotate more smoothly, which in turn makes the rotation of the storage part smoother and prevents any jamming.

[0016] In one optional embodiment, a limiting hole is formed on the surface of the universal ball, one end of the locking member is movably connected to the mounting part, and the locking member and the mounting part are relatively movable until the other end of the locking member is inserted into the limiting hole, the locking member restricts the relative sliding between the universal ball and the arc-shaped groove.

[0017] The advantage is that the limiting hole and the locking component are designed together to make the locking more secure and reliable, thus making the folding storage device more stable when unfolded.

[0018] In one alternative embodiment, the edge of the arc-shaped groove is recessed to form a limiting groove;

[0019] When the rod rotates relative to the placement part or the fixing part until the rod enters the limiting groove, the limiting groove restricts the relative rotation between the rod and the placement part or the fixing part, so that the relative position of the placement part and the fixing part remains fixed;

[0020] And / or, the end of the rod has a insertion hole, and a connecting rod is provided on the universal ball, the connecting rod being inserted and fixed into the insertion hole; when the rod rotates relative to the placement part or the fixing part until the connecting rod enters the limiting groove, the limiting groove restricts the relative rotation between the rod and the placement part or the fixing part, so that the relative position of the placement part and the fixing part remains fixed.

[0021] The advantage is that the limiting groove, in conjunction with the rod, prevents the storage part from shifting due to unintentional contact when the folding storage device is in its second unfolded state or when it is folded up, thus ensuring the overall stability of the folding storage device in its second unfolded state or when it is folded up.

[0022] In one alternative embodiment, at least one limiting groove is formed on the edge of the arc-shaped groove;

[0023] And / or, the fixing part is provided with a receiving cavity for storing items and a cover for opening or closing the receiving cavity.

[0024] The advantage is that the fixed part has a cavity for users to store items, which improves the utilization of space.

[0025] In an optional embodiment, the storage portion comprises a first storage plate and a second storage plate, which are respectively connected to the fixed portion via at least one lifting member. The first storage plate rotates about its corresponding second rotation axis to move closer to or further away from the fixed portion in the direction along the first rotation axis, and the second storage plate rotates about its corresponding second rotation axis to move closer to or further away from the fixed portion in the direction along the first rotation axis. When the first storage plate and the second storage plate rotate towards the fixed portion in the direction along the first rotation axis, they move away from each other, and when they rotate away from the fixed portion in the direction along the first rotation axis, they move closer to each other until they are assembled to form a complete storage portion.

[0026] The advantage is that the fixed part consists of two shelves, which can be placed on both sides of the fixed part. This allows items with distinct functions to be placed separately, making them easier to retrieve later.

[0027] In some embodiments, when the storage portion is driven to rotate forward about a first rotation axis, such that when the storage portion approaches the fixing portion in the direction along the first rotation axis until the outer wall of the lifting member abuts against the fixing portion, the folding storage device is in a folded state; when the storage portion is driven to rotate in the opposite direction about the first rotation axis, such that when the storage portion moves away from the fixing portion in the direction along the first rotation axis until the lifting member extends in the direction along the first rotation axis, the folding storage device is in an unfolded state.

[0028] The advantage is that when the storage unit abuts against the outer wall of the lifting component, the folding storage device is in a folded state. This design allows users to clearly know which position the storage unit is in before they need to drive it again, making it more convenient for users.

[0029] In some embodiments, the edge of the storage portion is connected to the edge of the fixed portion by a plurality of lifting members; when the storage portion is driven to rotate in the forward direction around a first rotation axis to the folded state, the plurality of lifting members are arranged between the storage portion and the fixed portion in a head-to-tail manner;

[0030] And / or, the first rotation axis passes through the geometric center or center of gravity of the placement part.

[0031] The advantages are that the multiple lifting components make the support of the storage unit more stable when the folding storage device is unfolded; the setting of the first rotating shaft passing through the center or center of gravity of the storage unit makes the storage unit more stable when it rotates.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0051] According to the appendix Figure 1-7As shown, this utility model embodiment relates to a folding storage device 1, including: a storage part 10, a fixing part 20, and a lifting member 30. The two ends of the lifting member 30 are rotatably connected to the storage part 10 and the fixing part 20, respectively. The storage part 10 is driven to rotate around a first rotating axis 40 or a second rotating axis. The two ends of the lifting member 30 rotate relative to the storage part 10 and the fixing part 20, respectively, so that the storage part 10 moves closer to or further away from the fixing part 20 in the direction along the first rotating axis 40. The first rotating axis 40 extends along the projection direction of the storage part 10 toward the fixing part 20 and passes through the storage part 10. The second rotating axis is perpendicular to the first rotating axis 40 and passes through the fixing part 20.

[0052] In this embodiment, the storage portion 10 is driven to rotate around the first rotation axis 40 or around the second rotation axis. This rotation causes the storage portion 10 to move closer to or further away from the fixing portion 20 in the direction of the first rotation axis 40. Figure 5 As shown, when the storage unit 10 is needed, it is driven to rotate forward around the first rotation axis 40, causing the storage unit 10 to move away from the fixing part 20. When it rotates to a preset position, it is in the first unfolded state, and the user can use the storage unit 10. When the storage unit 10 needs to be stored after use, it is rotated in the opposite direction, so that the storage unit 10 is close to the fixing part 20. Figure 4 As shown, when the user needs to unfold the storage unit 10 in the second rotation axis direction in the first unfolded state, the storage unit 10 is driven to rotate forward around the second rotation axis. When it rotates to the preset position, the storage unit 10 is close to the fixing part 20 in the direction of the first rotation axis 40, which is the second unfolded state. When the storage unit 10 needs to be stored after use, the storage unit 10 is rotated in the opposite direction. When the storage unit 10 rotates to the first unfolded state, the storage unit 10 is driven to rotate in the opposite direction along the first rotation axis 40 so that the storage unit 10 is close to the fixing part 20. The user controls the unfolding and folding of the folding storage device 1 by driving the storage unit 10 to rotate around different rotation axes, which greatly increases the diversity and fun of operation and improves the user experience.

[0053] like Figure 5 As shown, when the user needs to fold and store the storage device 1 in the first unfolded state, the storage part 10 is driven to rotate along the first rotating shaft 10, which in turn drives the lifting member 30 to rotate, thereby adjusting the storage part 10 to the first storage state. At this time, the sum of the storage areas of the storage part 10 and the fixing part 20 will not exceed the storage area of ​​the storage part 10. However, at this time, the required storage space of the folding and storage device 1 is minimal. When the space is extremely small, the folding and storage device 1 can be adjusted to this state; Figure 4As shown, when a user needs a larger storage area in the horizontal direction in the first unfolded state, they only need to move the storage part 10 along the second rotation axis so that the storage part 10 gradually approaches the fixing part 20 in the direction of the first rotation axis 10. When the storage part 10 is parallel to the fixing part 20, it is the second folded state. At this time, both the storage part 10 and the fixing part 20 can be used to place items, so that the sum of the storage areas of the storage part 10 and the fixing part 20 will not exceed twice the storage area of ​​the storage part 10 at most, and will not be less than the storage area of ​​the storage part 10 at least. When the user needs a larger storage area, the folding storage device 1 can be adjusted to this state. It can be seen that in this application solution, the user can rotate the storage part 10 along the first rotation axis 10 or the second rotation axis, and the storage area of ​​the folding storage device 1 will be different. In this way, the user can adopt different folding methods according to different usage scenarios, which improves the practicality of the folding storage device 1 and can meet the diverse usage needs of users in multiple life scenarios.

[0054] The storage section 10 can be a plate, a disc-shaped object that is high around the edges and low in the middle, or other objects, as long as it can serve the purpose of placing items. In this embodiment, a disc-shaped object is preferred because it is convenient to place items.

[0055] The fixing part 20 is used to support the storage part 10. It can be a solid square object, a plate-shaped object, or an object of other shapes, as long as it can support the storage part 10. This embodiment does not limit this.

[0056] The first rotating shaft 40 extends along the projection direction of the storage part 10 toward the fixing part 20 and passes through the storage part 10. The first rotating shaft 40 can extend along the orthogonal projection direction of the storage part 10 toward the fixing part 20 or along the oblique projection direction of the storage part 10 toward the fixing part 20. In this embodiment, the first rotating shaft 40 preferably extends along the orthogonal projection direction of the storage part 10 toward the fixing part 20. Furthermore, in this embodiment, the first rotating shaft 40 is preferably extended through the center of the storage part 10. This arrangement makes the force on the lifting member 30 more uniform when the storage part 10 rotates around the first rotating shaft 40, the rotation process more stable, and the user can rotate the storage part 10 more smoothly.

[0057] It should be noted that the second rotating shaft (not shown) is set perpendicular to the first rotating shaft 40, with the first rotating shaft 40 as the reference. Since the first rotating shaft 40 is set vertically relative to the fixed part 20, the second rotating shaft is a straight line extending horizontally relative to the fixed part 20. Figure 4 As shown, when the storage part 10 is driven to rotate relative to the fixed part 20 along the second rotation axis, the storage part 10 can move closer to or further away from the fixed part 20 in the direction of the first rotation axis 40.

[0058] The lifting component 30 serves as a connector, with its two ends rotatably connecting the storage part 10 and the fixing part 20, respectively. At the same time, when the folding storage device 1 is in the unfolded state, the lifting component 30 also serves as a support component, supporting the storage part 10 to remain in a fixed position.

[0059] See appendix Figure 1-3 In one optional embodiment, the lifting member 30 includes a rod 31, with universal joints 32 respectively provided at both ends of the rod 31. The rod 31 is connected to the storage part 10 and the fixing part 20 respectively through the universal joints 32.

[0060] The main body of the lifting component 30 is a rod 31, with universal joint assemblies 32 at both ends. The rod and the universal joint assemblies 32 can be detachably connected or integrally formed. This embodiment does not impose any restrictions on this.

[0061] It should be noted that the universal rotating assembly 32 is a component that can rotate in any direction. It can be a universal ball assembly or a universal joint assembly, as long as it can rotate at a large angle. This embodiment does not impose any restrictions on this. Since the universal rotating assembly 32 can rotate in any direction, when the storage part 10 is driven to rotate along the first rotating axis 40, the storage part 10 drives the rod 31 to rotate in any direction through the universal rotating assembly 32, thereby improving the flexibility of operation of the folding storage device 1.

[0062] like Figure 2-3 As shown, in an optional embodiment, the lifting member 30 further includes a locking member 33, which is configured to cooperate with the universal rotation assembly 32 between the rod 31 and the storage part 10, for locking the universal rotation assembly 32 and restricting the relative rotation of the rod 31 and the storage part 10 through the universal rotation assembly 32, so that the relative position between the fixed part 20 and the storage part 10 remains fixed; and / or, the locking member 33 is configured to cooperate with the universal rotation assembly 32 between the rod 31 and the fixed part 20, for locking the universal rotation assembly 32 and restricting the relative rotation of the rod 31 and the fixed part 20 through the universal rotation assembly 32, so that the relative position between the fixed part 20 and the storage part 10 remains fixed. During the rotation of the storage part 10 relative to the fixed part 20, when the storage part 10 rotates to a preset position relative to the fixed part 20, the locking member 33 locks the universal rotation assembly 32 between the storage part 10 and the rod 31, restricting the rotation of the universal rotation assembly 32, thereby keeping the storage part 10 in the preset position and preventing it from rotating, making the storage part 10 more stable and reliable when it is in the preset position; or the locking member 33 locks the universal rotation assembly 32 between the fixed part 20 and the rod 31, restricting the rotation of the universal rotation assembly 32, thereby keeping the storage part 10 in the preset position and preventing it from rotating, making the storage part 10 more stable and reliable when it is in the preset position.

[0063] The locking member 33 is used to lock the universal rotating assembly 32. One embodiment of the locking member 33 is that a groove is provided on the rotating part of the universal rotating assembly 32, and a movable protrusion is correspondingly provided on the locking member 33. When the storage part 10 rotates to a preset position, the protrusion is confined in the groove, restricting further rotation of the universal rotating assembly 32, thereby locking the storage part 10 in the preset position. Alternatively, the locking member 33 can be a clamping device with a toothed groove at the end. When the storage part 10 rotates to the preset position, the toothed groove can clamp the rotating part of the universal rotating assembly 32, restricting the universal rotating assembly 32. 2. Further rotation locks the storage unit 10 in a preset position. The locking element 33 can also be a damping structure. A damping element is provided below or above the rotating part of the universal rotating assembly 32. When the storage unit 10 rotates to the preset position, the damping element is just at the maximum damping position. At this time, the universal rotating assembly 32 needs a large driving force to rotate further, thereby limiting the further rotation of the universal rotating assembly 32 and locking the storage unit 10 in the preset position. Of course, the locking element 33 can also be other unlisted structures, as long as it can limit the further rotation of the universal rotating assembly 32.

[0064] It should be noted that the locking member 33 can be disposed on the universal rotating assembly 32, and can be fixedly or movably connected to the universal rotating assembly 32. In this embodiment, it is preferable that the locking member 33 is disposed on both the universal rotating assembly 32 between the rod 31 and the storage part 10 and the universal rotating assembly 32 between the rod 31 and the fixed part 20. During the rotation of the storage part 10 relative to the fixed part 20, when the storage part 10 rotates to a preset position relative to the fixed part 20, the locking member 33 locks the universal rotating assembly 32 between the rod 31 and the storage part 10 and the universal rotating assembly 32 between the rod 31 and the fixed part 20 respectively, so that the universal rotating assembly 32 cannot rotate further, thereby keeping the storage part 10 in the preset position. Regarding the positioning, it should be understood that the locking member 33 can lock the position of the storage part 10 relative to the fixed part 20 by locking either the universal rotation component 32 between the rod 31 and the storage part 10 or the universal rotation component 32 between the rod 31 and the fixed part 20. Of course, both can be locked simultaneously, which makes the storage part 10 more stably and reliably stay in the preset position relative to the fixed part 20. Of course, the locking member 33 can also be set on the rod 31, either fixedly connected to the rod 31 or detachably connected to the rod 31. When one end of the locking member 33 is fixed to the rod 31, the other end can move to limit the universal rotation component 32, so that the storage part 10 is kept in the preset position.

[0065] In one optional embodiment, the universal rotating assembly 32 includes a universal ball 321 and a mounting portion 322. The mounting portion 322 is provided with an arc-shaped groove 3221. The universal ball 321 is disposed in the arc-shaped groove 3221, and the outer wall of the universal ball 321 is slidable relative to the inner wall of the arc-shaped groove 3221. The locking member 33 is used to restrict the relative sliding between the universal ball 321 and the arc-shaped groove 3221. The cooperation between the universal ball 321 and the arc-shaped groove 3221 makes the rotation of the rod 31 connected to it smoother, thereby making the rotation of the storage portion 10 smoother and preventing jamming.

[0066] The universal ball 321 is slidably disposed in the arc-shaped groove 3221, and the other end can be connected to the rod body, or to the placement part 10 or the fixing part 20. Similarly, one end of the arc-shaped groove 3221 is connected to the universal ball 321, and the other end can be connected to the rod body 31 through the mounting part 322, or to the placement part 10 or the fixing part 20 through the mounting part 322. In this embodiment, it is preferred that one end of the universal ball 321 is slidably disposed in the arc-shaped groove and the other end is connected to the rod body 31, and the other end of the arc-shaped groove 3221 is connected to the fixing part 20 through the mounting part 322. This arrangement makes it convenient to install the universal ball 321 into the arc-shaped groove 3221, which is convenient for production and processing.

[0067] It should be noted that the inner wall of the arc-shaped groove 3221 and the outer wall of the universal ball 321 are mutually compatible arc-shaped surfaces, and the two surfaces can slide smoothly against each other, thereby enabling the universal rotating assembly 32 to rotate smoothly. As for the external shape of the arc-shaped groove 3221, it can be circular, square, or any other arbitrary shape, which is not limited in this embodiment.

[0068] It should be noted that the omnidirectional ball 321 can be a whole sphere, or only the part that slides in conjunction with the arc-shaped groove 3221 can be spherical, while the shape of the other parts can be cylindrical, square, or other shapes. This embodiment does not impose any restrictions.

[0069] In one optional embodiment, a limiting hole 3211 is provided on the surface of the universal ball 321. One end of the locking member 33 is movably connected to the mounting part 322. When the locking member 33 and the mounting part 322 move relative to each other until the other end of the locking member 33 is inserted into the limiting hole 3211, the locking member 33 restricts the relative sliding between the universal ball 321 and the arc-shaped groove 3221. The limiting hole 3211 and the locking member 33 are configured to cooperate, making the locking more stable and reliable, thereby making the folding storage device 1 more stable when unfolded and used.

[0070] The limiting hole 3211 used to cooperate with the locking member 33 can be hole-shaped or groove-shaped. When the locking member 33 enters the limiting hole 3211 or the limiting groove 32211, it can limit the universal ball 321, thereby restricting the universal ball 321 from rotating further, so that the placement part 10 can be stably stopped in the preset position relative to the fixed part 20.

[0071] In one optional embodiment, the edge of the arc-shaped groove 3221 is recessed to form a limiting groove 32211; when the rod 31 rotates relative to the placement part 10 or the fixing part 20 until the rod 31 enters the limiting groove 32211, the limiting groove 32211 restricts the relative rotation between the rod 31 and the placement part 10 or the fixing part 20, so that the relative position of the placement part 10 and the fixing part 20 remains fixed; and / or, the end of the rod 31 has a insertion hole 311, and a connecting rod 3212 is provided on the universal ball 321, and the connecting rod 3212 is inserted and fixed into the insertion hole 311. When the rod 31 rotates relative to the storage part 10 or the fixing part 20 until the connecting rod 3212 enters the limiting groove 32211, the limiting groove 32211 restricts the relative rotation between the rod 31 and the storage part 10 or the fixing part 20, so that the relative position of the storage part 10 and the fixing part 20 remains fixed. The limiting groove 32211 is set in conjunction with the rod 31 so that the storage part 10 will not be deflected due to unintentional touch when the folding storage device 1 is in the second unfolded state or the storage state, thus ensuring the stability of the overall structure of the folding storage device 1 in the second unfolded state or the storage state.

[0072] The limiting groove 32211 is formed by the recessed edge of the arc-shaped groove 3221. It can be circular, square or other irregular shapes, as long as it can restrict the relative rotation between the rod 31 and the storage part 10 or the fixing part 20. It should be noted that the opening of the limiting groove 32211 must be greater than or equal to the outer diameter of the rod 31 or the connecting rod 3212. In this embodiment, the opening of the limiting groove 32211 is preferably greater than the outer diameter of the rod 31 or the connecting rod. Since the opening of the limiting groove 32211 is greater than the outer diameter of the rod 31 or the connecting rod 3212, when the storage part 10 rotates relative to the fixing part 20 in the direction of the first rotation axis 40 and approaches the fixing part 20, the rod 31 can be smoothly rotated into the limiting groove 32211, so as to make it more convenient for the user to operate the folding and storage device 1.

[0073] In one alternative embodiment, the edge of the arc-shaped groove 3221 is formed with at least one limiting groove 32211; and / or, the fixing part 20 is provided with a receiving cavity 21 for storing items and a cover plate 22 for opening or closing the receiving cavity 21. The fixing part 20 is provided with a receiving cavity 21 for storing items, thereby improving the utilization of space.

[0074] The limiting groove 32211 can be set as one or four in the circumferential direction. In this embodiment, it is preferred to set four. In this way, no matter which direction the storage part 10 is rotated relative to the fixed part 20 along the second rotation axis, when it rotates close to the fixed part 20, the rod 31 can be limited by the limiting groove 32211, thereby ensuring the flexibility of operation of the folding storage device 1.

[0075] It should be noted that in this embodiment, the fixing part 20 is hollow, and its interior is provided with a receiving cavity 21 for storing items. At the same time, a cover plate 22 is provided on the outside of the cavity, which is used to open or close the cavity. Furthermore, the interior of the receiving cavity 21 can be a complete large cavity, or it can be divided into multiple separate small cavities by partitions. Similarly, the cover plate 22 can be set to open from the left and right, or from the top and bottom, or it can be set as a drawer. This embodiment does not limit this.

[0076] See appendix Figure 7 In one optional embodiment, the storage section 10 is divided into a first storage plate 11 and a second storage plate 12. The first storage plate 11 and the second storage plate 12 are respectively connected to the fixing section 20 through at least one lifting member 30. The first storage plate 11 rotates around its corresponding second rotation axis to move closer to or away from the fixing section 20 in the direction along the first rotation axis 40. The second storage plate 12 rotates around its corresponding second rotation axis to move closer to or away from the fixing section 20 in the direction along the first rotation axis 40. When the first storage plate 11 and the second storage plate 12 rotate towards the fixing section 20 in the direction along the first rotation axis 40, they move away from each other. When the first storage plate 11 and the second storage plate 12 rotate away from the fixing section 20 in the direction along the first rotation axis 40, they move closer to each other until they are assembled to form a complete storage section 10. The storage section 10 can be divided into two storage plates, and the two storage plates can be placed on both sides of the fixing section 20. This allows items with significantly different functions to be placed separately, facilitating subsequent retrieval and placement.

[0077] The first shelf 11 and the second shelf 12 can be connected to the fixed part 20 by one lifting member 30 or by multiple lifting members 30. In this embodiment, the first shelf 11 and the second shelf 12 are connected to the fixed part 20 by two lifting members 30, so that when the shelf 10 is in a state away from the fixed part 20, the support of the two lifting members 30 can make the shelf 10 more stably fixed in the current position.

[0078] In some embodiments, the storage unit 10 is driven to rotate forward about the first rotation axis 40, such that when the storage unit 10 approaches the fixing part 20 along the first rotation axis 40 until the outer wall of the lifting member 30 abuts against the fixing part 20, the folding and storage device 1 is in a folded state; when the storage unit 10 is driven to rotate in the opposite direction about the first rotation axis 40, such that when the storage unit 10 moves away from the fixing part 20 along the first rotation axis 40 until the lifting member 30 extends along the first rotation axis 40, the folding and storage device 1 is in an unfolded state; in this embodiment, when the storage unit 10 abuts against the outer wall of the lifting member 30, the folding and storage device 1 is in a folded state. This arrangement allows the user to clearly know which position the storage unit 10 is rotated to before driving it again, making it convenient for the user.

[0079] In some embodiments, the edge of the storage section 10 is connected to the edge of the fixing section 20 by a plurality of lifting members 30; when the storage section 10 is driven to rotate in the forward direction around the first rotation axis 40 to the folded state, the plurality of lifting members 30 are arranged in a head-to-tail manner between the storage section 10 and the fixing section 20; and / or, the first rotation axis 40 passes through the geometric center or center of gravity of the storage section 10, and the arrangement of the plurality of lifting members 30 makes the support of the lifting members 30 for the storage section 10 more stable when the folding storage device 1 is unfolded; the first rotation axis 40 is arranged to pass through the center or center of gravity of the storage section 10, which makes the storage section 10 more stable when rotating.

[0080] It should be noted that there can be two or more lifting components 30. In this embodiment, four are preferred. Each lifting component 30 supports the four sides of the storage part 10, so that the support of the lifting component 30 for the storage part 10 is more stable when the folding storage device 1 is unfolded.

[0081] See appendix Figure 1-7The following is a general description of a preferred embodiment of the present invention. In this embodiment, the storage part 10 of the folding storage device 1 is a square tabletop, the fixing part 20 is a hollow, roughly regular cube, four lifting components 30 are provided, and four universal rotating components 32 are simultaneously provided. Each universal rotating component 32 includes a universal ball 321 and a locking component 33. The first rotating axis 40 is an extension line extending from the storage part 10 to the fixing part 20, i.e., from the vertical direction downwards through the center of the storage part 10. The second rotating axis is parallel to any edge of the upper surface of the fixing part 20. When the user needs to switch the folding storage device 1 from the storage state to the unfolded state, the storage part 10 is first driven to rotate clockwise around the first rotating axis 40. When it rotates to the maximum height, i.e., when the lifting components 30 are perpendicular to the storage part 10 and the fixing part 20 respectively, the locking component 33 locks the universal ball 321 to prevent the universal ball 321 from rotating further. At this time, the folding storage device 1 is in the first unfolded state, and the user can... Using the storage unit 10; when the user needs to switch to the second unfolded state, first release the locking member 33 from the universal ball 321, and then drive the storage unit 10 to rotate in the forward direction relative to the fixed part 20 around the second rotation axis. When the storage unit 10 and the fixed part 20 are closest in the vertical direction, the folding and storage device 1 is in the second unfolded state, and the user can use the storage unit 10 in the direction of the second rotation axis. In this way, the device can be used in places with low height. When the user needs to put away the folding and storage device 1, since it is in the second unfolded state, the storage unit 10 needs to be driven in the reverse direction to rotate the storage unit 10 to the first unfolded state. Then drive the storage unit 10 to rotate counterclockwise around the first rotation axis 40. When it is rotated to the minimum height, that is, when the distance between the storage unit 10 and the fixed part 20 is the minimum in the vertical direction, the folding and storage device 1 is in the stored state. In this way, after each use, only a small space is needed for the user to put away the folding and storage device 1.

[0082] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
