Description

Technical Field

[0001] This application relates to the field of elevator technology, and more specifically to three-dimensional cargo handling devices and parking lots. Background Technology

[0002] Layered storage is an efficient way to utilize limited space and improve space utilization. This can be achieved by using multiple liftable support units to conveniently support items in layers. However, existing support units are installed using a movable, suspended method, causing the center of gravity to naturally sag. This makes the support unit prone to swaying when raised, which can easily cause the stored items inside to tip over.

[0003] Therefore, some three-dimensional loading devices incorporate clamping components to hold the stored items within the support structure, preventing them from tipping over when the support structure sways. However, the use of clamping devices complicates the structure of the three-dimensional loading device and increases production costs.

[0004] Therefore, how to provide a three-dimensional loading device that can conveniently and stably achieve layered support of stored items and has a simplified structure remains a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, in order to solve the above-mentioned technical problems, this application provides a three-dimensional loading device and a parking lot.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a three-dimensional object-carrying device, which includes:

[0007] The first lifting mechanism has multiple first hinge parts, which are spaced apart along the first lifting closed path and can move along the first lifting closed path.

[0008] The second lifting mechanism has multiple second hinge parts, which are spaced apart along the second lifting closed path and can move along the second lifting closed path.

[0009] And multiple support sections, which are spaced apart along the first lifting closed path; the support sections are used to carry the stored items;

[0010] The bearing portion includes a third hinge portion that is hinged to the first hinge portion and a fourth hinge portion that is hinged to the second hinge portion. The axis of the third hinge portion and the axis of the fourth hinge portion are offset along a first offset direction, and the first lifting closed path and the second lifting closed path are offset along a second offset direction. The first offset direction and the second offset direction are in the same direction, so that the third hinge portion can translate in the same direction as the fourth hinge portion, thereby enabling the bearing portion to achieve translational lifting.

[0011] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a parking lot equipped with the above-mentioned three-dimensional cargo storage device, which stores vehicles.

[0012] Beneficial Effects: Unlike existing technologies, this application offers at least three beneficial effects. First, by aligning the first and second offset directions in the same direction, the supporting components enable translational lifting, facilitating layered support of stored items through the translational lifting of multiple supporting components. Second, the application utilizes the first and second hinges to support the third and fourth hinges, whose axes are offset along the first offset direction, thereby improving the stability of the stored items supported on the supporting components. Third, the structure for stable support of stored items in this application is simpler than that in existing technologies. Specifically, even without additional clamping components as in existing technologies, the first and second offset directions, aligned in the same direction, allow for stable support of stored items by supporting the third and fourth hinges, whose axes are offset along the first offset direction. In summary, the three-dimensional storage device of this application provides convenient and stable layered support of stored items with a simplified structure. Attached Figure Description

[0037] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Furthermore, all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0039] Example 1

[0040] Please see Figures 1-6 The three-dimensional carrying device 10 of this application includes a first lifting mechanism 100, a second lifting mechanism 200, and a plurality of supporting parts 300.

[0041] The first lifting mechanism 100 has a plurality of first hinge parts 110, which are spaced apart along the first lifting closed path 101 and can move along the first lifting closed path 101.

[0042] The second lifting mechanism 200 has a plurality of second hinge parts 210, which are spaced apart along the second lifting closed path 201 and can move along the second lifting closed path 201.

[0043] Multiple support units 300 are spaced apart along the first lifting closed path 101; the support units 300 are used to support and store items.

[0044] The support unit 300 includes a third hinge 310 that hinges to the first hinge 110 and a fourth hinge 320 that hinges to the second hinge 210. The axis L1 of the third hinge 310 and the axis L2 of the fourth hinge 320 are offset along a first offset direction e1, and the first lifting closed path 101 and the second lifting closed path 201 are offset along a second offset direction e2. The first offset direction e1 and the second offset direction e2 are aligned so that the third hinge 310 and the fourth hinge 320 can translate in the same direction, enabling the support unit 300 to achieve translational lifting. It should be noted that translational lifting means that the support unit 300 can rise and fall by translating.

[0045] It should be noted that the stored items are those stored in the support section 300. Layered storage of the stored items can be achieved through multiple support sections 300 spaced apart along the first lifting closed path 101. The stored items can be vehicles, pallets, daily necessities, workpieces or materials used in the production process, but are not limited to these. Pallets are items stacked together. Daily necessities include, but are not limited to, toiletries, tableware, or food, and are not specifically limited to these categories.

[0046] In some examples (not shown), the carrier section may be equipped with a conveyor device including a conveyor belt for receiving items input into the carrier section and outputting items carried in the carrier section. This enables automatic loading and unloading of items.

[0047] The above-described method offers at least three beneficial effects. First, by aligning the first offset direction e1 and the second offset direction e2 in the same direction, the supporting portion 300 can achieve translational lifting, enabling convenient layered support of stored items through the translational lifting of multiple supporting portions 300. Second, the first hinge portion 110 and the second hinge portion 210 respectively support the third hinge portion 310 and the fourth hinge portion 320, whose axes are offset along the first offset direction e1, thereby improving the stability of the stored items supported on the supporting portion 300. Third, the structure for supporting stable load-bearing of stored items in this application is simpler than the structures for supporting stable load-bearing of stored items in the prior art. Specifically, even with the additional clamping components used in existing technologies, the present application ensures stable support of stored items by using a first offset direction e1 and a second offset direction e2 aligned in the same direction. This allows the first hinge portion 110 and the second hinge portion 210 to respectively support the third hinge portion 310 and the fourth hinge portion 320, whose axes are offset along the first offset direction e1, thus ensuring stable support of stored items. In summary, the three-dimensional storage device 10 of this application can conveniently and stably achieve layered support of stored items while simplifying the structure.

[0048] It should be noted that, as Figures 1-6 As shown, in the same bearing section 300, the speed at which the first hinge section 110, to which the third hinge section 310 is hinged, moves in the first lifting closed path 101 is taken as the first speed, and the speed at which the second hinge section 210, to which the fourth hinge section 320 is hinged, moves in the second lifting closed path 201 is taken as the second speed. Then, the first offset direction e1 and the second offset direction e2 are set in the same direction, so that the direction of the first speed is the same as the direction of the second speed, and the magnitude of the first speed is equal to the magnitude of the second speed. This allows the third hinge section 310 to translate in the same direction as the fourth hinge section 320, enabling the bearing section 300 to achieve translational lifting.

[0049] Optionally, the shape of the first lifting closed path 101 is the same as that of the second lifting closed path 201. The center of the area enclosed by the first lifting closed path 101 is designated as the first center O1, and the center of the area enclosed by the second lifting closed path 201 is designated as the second center O2.

[0050] In this configuration, the axis L1 of the third hinge portion 310 and the axis L2 of the fourth hinge portion 320 are both perpendicular to the plane containing the second lifting closed path 201. Viewed from the orthographic projection determined by the plane containing the second lifting closed path 201, the first center O1 and the second center O2 are offset along the second offset direction e2, and the first lifting closed path 101 and the second lifting closed path 201 are translated and offset along the second offset direction e2. This improves the stability of the lifting of the bearing portion 300.

[0051] It should be noted that the translational offset of the first lifting closed path 101 and the second lifting closed path 201 along the second offset direction e2 means that the first lifting closed path 101 and the second lifting closed path 201 are offset along the second offset direction e2, and if the first lifting closed path 101 is translated along the second offset direction e2 to the second lifting closed path 201, the first lifting closed path 101 can overlap with the second lifting closed path 201. That is, the first lifting closed path 101 and the second lifting closed path 201 are translated symmetrically.

[0052] For example, and not as a limitation, the shapes of the first lifting closed path 101 and the second lifting closed path 201 can be designed as needed, as long as the shapes of the first lifting closed path 101 and the second lifting closed path 201 are the same.

[0053] Optionally, the angle between the first offset direction e1 and the horizontal plane is taken as the first included angle, and the angle between the second offset direction e2 and the horizontal plane is taken as the second included angle. The first included angle and the second included angle are the same and both are 0 degrees to 90 degrees.

[0054] In the first example, the support portion 300 is formed as a fully open structure, where both the first and second included angles can be 0 degrees, making the fully open structure parallel to the horizontal plane. The fully open structure is, for example, a flat plate structure, but is not limited to this.

[0055] In the second example (not shown), the support portion is formed as a fully open structure, with both the first and second included angles being 10 degrees, causing the fully open structure to be inclined relative to the horizontal plane. The fully open structure is, for example, a flat plate structure, but is not limited to this.

[0056] In the third example (not shown), the supporting part is formed as a semi-open structure, such as an L-shaped structure, which includes a horizontal plate and a vertical plate. The third and fourth hinge parts are provided on the vertical plate, and the first and second included angles can both be 90 degrees, so that the horizontal plate is parallel to the horizontal plane.

[0057] In the fourth example (not shown), the support portion is formed as a semi-open structure, and the first included angle and the second included angle can both be 0 degrees, 45 degrees or 90 degrees, but are not limited to these.

[0058] In the fifth example (not shown), the support part is formed as an openable closed structure, and the first included angle and the second included angle can both be 0 degrees, 22 degrees, 45 degrees, 60 degrees or 90 degrees.

[0059] Optionally, such as Figures 1-6 As shown, viewed from the orthographic projection defined by the plane containing the second lifting closed path 201, within the same bearing portion 300, the distance between the axis L1 of the third hinge portion 310 and the axis L2 of the fourth hinge portion 320 is defined as the first offset distance d1, and the distance between the first center O1 and the second center O2 is defined as the second offset distance d2. The first offset distance d1 is equal to the second offset distance d2. This improves the stability of the lifting of the bearing portion 300.

[0060] Optionally, such as Figures 1-6 As shown, when viewed from the orthographic projection of the plane where the second lifting closed path 201 is located, the area enclosed by the first lifting closed path 101 and the area enclosed by the second lifting closed path 201 are divided into an overlapping area Q1, a first staggered area Q2, and a second staggered area Q3.

[0061] The overlapping region Q1 is the portion where the region enclosed by the first lifting closed path 101 and the region enclosed by the second lifting closed path 201 overlap. The first offset region Q2 is the portion where the region enclosed by the first lifting closed path 101 is offset from the overlapping region Q1. The second offset region Q3 is the portion where the region included by the second lifting closed path 201 is offset from the overlapping region Q1.

[0062] The first lifting mechanism 100 and the second lifting mechanism 200 are located on opposite sides of the supporting portion 300. The first offset region Q2 and the second offset region Q3 are offset along the second offset direction e2 on both sides of the overlapping region Q1. At least one supporting portion 300 extends at least partially into the overlapping region Q1, and the portion of the supporting portion 300 extending into the overlapping region Q1 is located between the first lifting mechanism 100 and the second lifting mechanism 200.

[0063] The above method can improve the utilization rate of space and make the multiple load-bearing parts 300, the first lifting mechanism 100 and the second lifting mechanism 200 more compactly assembled.

[0064] Optionally, combined Figures 1-6 See Figures 7-11 As shown, the three-dimensional carrying device 10 includes a drive assembly 400.

[0065] In one example, the drive assembly 400 is connected to the first lifting mechanism 100 and the second lifting mechanism 200 respectively to drive the first lifting mechanism 100 to move the first hinge portion 110 along the first lifting closed path 101, and to drive the second lifting mechanism 200 to move the second hinge portion 210 along the second lifting closed path 201.

[0066] In another example, the drive assembly 400 is driven to either the first lifting mechanism 100 or the second lifting mechanism 200 to drive the first lifting mechanism 100 to move the first hinge portion 110 along the first lifting closed path 101, and to drive the second lifting mechanism 200 via the bearing portion 300 to move the second hinge portion 210 along the second lifting closed path 201.

[0067] For ease of explanation, the following embodiments will be described using the example of the drive assembly 400 being connected to the first lifting mechanism 100 and the second lifting mechanism 200 respectively.

[0068] Optionally, combined Figures 1-6 See Figures 7-11 As shown, the drive assembly 400 includes a drive device 410 and a linkage assembly 420. The linkage assembly 420 is connected to the drive device 410 in a transmission manner, and the linkage assembly 420 has a first linkage end 421 and a second linkage end 422 that rotate synchronously.

[0069] The first linkage end 421 is driven to the first lifting mechanism 100 to drive the first lifting mechanism 100 to move the first hinge part 110 along the first lifting closed path 101. The second linkage end 422 is driven to the second lifting mechanism 200 to drive the second lifting mechanism 200 to move the second hinge part 210 along the second lifting closed path 201.

[0070] By using the above method, the synchronization of the movement of the first lifting mechanism 100 and the second lifting mechanism 200 can be improved by using the first linkage end 421 and the second linkage end 422 to drive the first lifting mechanism 100 and the second lifting mechanism 200 respectively. This can avoid or reduce the jamming caused by the speed imbalance between the first hinge part 110 hinged by the third hinge part 310 and the second hinge part 210 hinged by the fourth hinge part 320 in the same bearing part 300.

[0071] Optionally, combined Figures 1-6 See Figures 7-11 As shown, the linkage component 420 includes a linkage shaft 424, a first linkage wheel 421a, and a second linkage wheel 422a.

[0072] The linkage shaft 424 is connected to the drive device 410 and passes through the drive device 410, protruding from both ends of the drive device 410. The first linkage end 421 is formed as a first linkage wheel 421a, which is located at one end of the linkage shaft 424 protruding from the drive device 410. The second linkage end 422 is formed as a second linkage wheel 422a, which is located at the other end of the linkage shaft 424 protruding from the drive device 410.

[0073] By using the above method, the synchronization of the movement of the first linkage wheel 421a and the second linkage wheel 422a can be improved by using the linkage shaft 424 for transmission. In turn, the synchronization of the movement of the first hinge 110 hinged to the third hinge 310 and the second hinge 210 hinged to the fourth hinge 320 in the same bearing part 300 can be improved, so as to reduce jamming.

[0074] Optionally, in one example, the first linkage wheel 421a and the second linkage wheel 422a can be respectively connected to the first lifting mechanism 100 and the second lifting mechanism 200 via corresponding third flexible traction members 423. By way of example, and not limitation, the third flexible traction member 423 may include, but is not limited to, a transmission belt or a transmission chain.

[0075] Alternatively, in another example (not shown), the first linkage wheel and the second linkage wheel can be connected to the first lifting mechanism and the second lifting mechanism respectively through corresponding gear systems.

[0076] Optionally, combined Figures 1-6 See Figures 7-11 As shown, the three-dimensional carrying device 10 may include a device housing 600, with a first lifting mechanism 100, a second lifting mechanism 200, and a drive assembly 400 disposed within the device housing 600. For example, but not as a limitation, the device housing 600 may be a semi-open structure or an openable / closable closed structure to facilitate the placement and retrieval of stored items within the device housing 600.

[0077] Optionally, see Figures 1-11 As shown, the first lifting mechanism 100 can be a first flexible traction lifting mechanism 100a, and the second lifting mechanism 200 can be a second flexible traction lifting mechanism 200a.

[0078] The first flexible traction lifting mechanism 100a includes a first flexible traction member 120a, a first upper rotating wheel 130a, and a first lower rotating wheel 140a. The first upper rotating wheel 130a and the first lower rotating wheel 140a are arranged vertically at intervals. The first flexible traction member 120a passes around the first upper rotating wheel 130a and the first lower rotating wheel 140a along a first lifting closed path 101, and a plurality of first hinge portions 110 are arranged at intervals along the first lifting closed path 101 on the first flexible traction member 120a. The first linkage end 421 is drivenly connected to the first upper rotating wheel 130a or the first lower rotating wheel 140a to drive the first flexible traction member 120a to rotate, causing the first hinge portions 110 to move along the first lifting closed path 101.

[0079] The second flexible traction lifting mechanism 200a includes a second flexible traction member 220a, a second upper rotating wheel 230a, and a second lower rotating wheel 240a. The second upper rotating wheel 230a and the second lower rotating wheel 240a are arranged vertically at intervals. The second flexible traction member 220a passes around the second upper rotating wheel 230a and the second lower rotating wheel 240a along the second lifting closed path 201, and a plurality of second hinge portions 210 are arranged at intervals along the second lifting closed path 201 on the second flexible traction member 220a. The second linkage end 422 is connected to the second upper rotating wheel 230a or the second lower rotating wheel 240a for transmission, so as to drive the second flexible traction member 220a to rotate, causing the second hinge portions 210 to move along the second lifting closed path 201.

[0080] In the above manner, the first flexible traction member 120a and the second flexible traction member 220a are flexible structures. Thus, through flexible deformation, the shape of the first lifting closing path 101 and the second lifting closing path 201 can be flexibly changed to configure a suitable shape as needed.

[0081] Optionally, see Figures 1-11 As shown, the first upper rotating wheel 130a, the first lower rotating wheel 140a, the second upper rotating wheel 230a, and the second lower rotating wheel 240a can be pulleys. The first flexible traction member 120a can be a first flexible belt 120a-1, and the second flexible traction member 220a can be a second flexible belt 220a-1.

[0082] Optionally, see Figures 1-11 As shown, the first hinge portion 110 may include, but is not limited to, a first hinge hole 111a directly or indirectly disposed in the first flexible strip 120a-1, and the second hinge portion 210 may include, but is not limited to, a second hinge hole 211a directly or indirectly disposed in the second flexible strip 220a-1. The third hinge portion 310 includes, but is not limited to, a third hinge shaft 311a directly or indirectly disposed in the support portion 300, and the fourth hinge portion 320 includes, but is not limited to, a fourth hinge shaft 321a directly or indirectly disposed in the support portion 300.

[0083] The first hinge hole 111a is hinged to the third hinge shaft 311a, and the second hinge hole 211a is hinged to the fourth hinge shaft 321a. The axis L1 of the third hinge part 310 can be the axis of the third hinge shaft 311a, and the axis L2 of the fourth hinge part 320 can be the axis of the fourth hinge shaft 321a.

[0084] Optionally, in other alternative examples (not shown), the first hinge portion may include, but is not limited to, a first hinge shaft directly or indirectly disposed on the first flexible belt, and the second hinge portion may include, but is not limited to, a second hinge shaft directly or indirectly disposed on the second flexible belt. The third hinge portion may include, but is not limited to, a third hinge hole directly or indirectly disposed on the support portion. The fourth hinge portion may include, but is not limited to, a fourth hinge hole directly or indirectly disposed on the support portion.

[0085] The first hinge shaft is hinged to the third hinge hole, and the second hinge shaft is hinged to the fourth hinge hole; the axis of the third hinge part is the axis of the third hinge hole, and the axis of the fourth hinge part is the axis of the fourth hinge hole.

[0086] Example 2

[0087] contrast Figures 1-11 See Figures 12-14 As shown, Embodiment 2 is a further refinement based on Embodiment 1. The similarities between Embodiment 2 and Embodiment 1 will not be repeated. The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the first flexible belt 120a-1 in Embodiment 1 is replaced by the first conveyor chain 120a-2, and the second flexible belt 220a-1 in Embodiment 1 is replaced by the second conveyor chain 220a-2, as detailed below.

[0088] Optionally, compare Figures 1-11 See Figures 12-14 As shown, the first upper rotating wheel 130a, the first lower rotating wheel 140a, the second upper rotating wheel 230a, and the second lower rotating wheel 240a can be sprockets. The first flexible traction member 120a can be a first conveyor chain 120a-2, and the second flexible traction member 220a can be a second conveyor chain 220a-2. Both the first conveyor chain 120a-2 and the second conveyor chain 220a-2 include multiple conveyor chain plates 121 that are sequentially hinged. The first hinge portion 110 and the second hinge portion 210 both include a transition plate 11-1 and a hinge seat 11-2. The transition plate 11-1 is integrally formed with a conveyor chain plate 121. The hinge seat 11-2 is disposed on the transition plate 11-1. The third hinge portion 310 and the fourth hinge portion 320 are respectively hinged to the corresponding hinge seats 11-2.

[0089] By using the above method, the hinge seat 11-2 is provided by the adapter plate 11-1 integrally formed with the conveyor chain plate 121, which enables the hinge seat 11-2 of the first hinge part 110 to be more stably installed on the first conveyor chain 120a-2, and the hinge seat 11-2 of the second hinge part 210 to be more stably installed on the second conveyor chain 220a-2.

[0090] Optionally, compare Figures 1-11 See Figures 12-14 As shown, the hinge base 11-2 can be fixed to the adapter plate 11-1 by a plurality of threaded connectors 11-3, but is not limited thereto. In other alternative embodiments, the hinge base 11-2 can be integrally formed with the adapter plate 11-1.

[0091] Optionally, compare Figures 1-11 See Figures 12-14 As shown, the adapter plate 11-1 may include a first plate portion 11-11 and a second plate portion 11-12. The first plate portion 11-11 is connected to a corresponding conveyor chain plate 121 and is coplanar with the corresponding conveyor chain plate 121.

[0092] The second plate portion 11-12 of the first hinge portion 110 is bent relative to the first plate portion 11-11 towards the side closer to the third hinge portion 310, and the second plate portion 11-12 of the first hinge portion 110 is provided with a corresponding hinge seat 11-2.

[0093] By means of the above method, the structural strength of the transition plate 11-1 can be improved by bending the second plate portion 11-12 relative to the first plate portion 11-11.

[0094] Optionally, compare Figures 1-11 See Figures 12-14 As shown, the hinge seat 11-2 is provided with a hinge hole 11-21, and a bearing 11-4 is embedded in the hinge hole 11-21. The third hinge part 310 and the fourth hinge part 320 are respectively hinged to the corresponding bearings 11-4.

Adjacent conveyor chain plates 121 in the first side chain plate group 12-2 and adjacent conveyor chain plates 121 in the second side chain plate group 12-3 are hinged together by chain plate hinge parts 12-1. The adapter plate 11-1 is integrally formed with one conveyor chain plate 121 in the second side chain plate group 12-3.

[0097] The first conveyor chain 120a-2 and the second conveyor chain 220a-2 are each provided with a guide rail 500. The guide rail 500 has a chain plate guide groove 501 and a hinge clearance groove 502 that connect in layers from the inside of the guide rail 500 to the outside. The chain plate guide groove 501 guides and engages with the first side chain plate assembly 12-2. The hinge clearance groove 502 avoids the chain plate hinge portion 12-1. The side wall of the hinge clearance groove 502 blocks the first side chain plate assembly 12-2 to prevent the first side chain plate assembly 12-2 from disengaging from the hinge clearance groove 502 and the chain plate guide groove 501.

[0098] By using the guide rail 500 corresponding to the first conveyor chain 120a-2 to guide the first conveyor chain 120a-2 in the above manner, the smoothness of the rotation of the first conveyor chain 120a-2 can be improved, and the shaking of the first conveyor chain 120a-2 can be avoided or reduced; by using the guide rail 500 corresponding to the second conveyor chain 220a-2 to guide the second conveyor chain 220a-2, the smoothness of the rotation of the second conveyor chain 220a-2 can be improved, and the shaking of the second conveyor chain 220a-2 can be avoided or reduced.

[0099] Optionally, compare Figures 1-11 See Figures 12-14 As shown, the chain plate hinge portion 12-1 passes through the conveyor chain plate 121 of the first side chain plate assembly 12-2, partially protruding from the outside of the conveyor chain plate 121 of the first side chain plate assembly 12-2. The guide rail 500 is provided with a protrusion clearance groove 503, and the protrusion clearance groove 503, the chain plate guide groove 501, and the hinge portion clearance groove 502 are connected in layers from the inside of the guide rail 500 to the outside of the guide rail 500. The protrusion clearance groove 503 avoids the portion of the chain plate hinge portion 12-1 that protrudes from the outside of the conveyor chain plate 121 of the first side chain plate assembly 12-2.

[0100] Example 3

[0101] contrast Figures 1-11 See Figures 15-16As shown, Embodiment 3 is a further refinement based on Embodiment 1. The similarities between Embodiment 3 and Embodiment 1 will not be repeated.

[0103] The first rotating frame type lifting mechanism 100b includes a first rotating frame 120b. A first lifting closed path 101 extends circumferentially around the first rotating frame 120b, and a plurality of first hinge portions 110 are spaced apart along the first lifting closed path 101 on the first rotating frame 120b. A first linkage end 421 is drively connected to the first rotating frame 120b to drive the first rotating frame 120b to rotate, causing the first hinge portions 110 to move along the first lifting closed path 101.

[0104] The second rotating frame type lifting mechanism 200b includes a second rotating frame 220b. A second lifting closed path 201 extends circumferentially around the second rotating frame 220b, and a plurality of second hinge portions 210 are spaced apart along the second lifting closed path 201 on the second rotating frame 220b. A second linkage end 422 is drively connected to the second rotating frame 220b to drive the second rotating frame 220b to rotate, causing the second hinge portions 210 to move along the second lifting closed path 201.

[0105] It should be noted that both the first rotating frame 120b and the second rotating frame 220b can be made of rigid structure to stably support the load-bearing part 300. For example, and not as a limitation, the first rotating frame 120b and the second rotating frame 220b can be disc-shaped rotating frames, annular rotating frames, or radial rotating frames.
