[0036] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms "a", "the" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items. It should also be understood that the term "plurality" used herein means including at least two.

[0039] Unless otherwise specified, ordinal numbers such as "first" and "second" in the embodiments of this application are used to distinguish multiple objects and are not used to define the order, timing, priority, or importance of multiple objects. For example, the first drive motor and the second drive motor are only used to distinguish the two support columns.

[0040] Alternatively, as Figure 1-4 As shown, the lifting and rotating platform system of the stereo garage can include a fixed assembly frame 1, a lifting assembly frame 2, a rotating assembly frame 3 and a control motor 4. The bottom end of the fixed assembly frame 1 can be fixed to the bottom ground of the foundation pit 100. The height of the fixed assembly frame 1 can be lower than the depth H of the foundation pit 100.

[0041] Alternatively, as Figure 1-4 As shown, the lifting assembly 2 may include a plurality of lifting guide columns 21 and a lifting platform 22. The bottom ends of the plurality of lifting guide columns 21 may be fixed to the two side ends of the fixed assembly 1, and the lifting guide columns 21 may be perpendicular to the bottom surface of the foundation pit 100. The lifting platform 22 may be arranged between the plurality of lifting guide columns 21 and connected to the plurality of lifting guide columns 21. The lifting platform 22 can be raised and lowered relative to the plurality of lifting guide columns 21.

[0042] Alternatively, as Figure 1-4 As shown, the rotating assembly frame 3 may include a rotating platform 31 and a rotating assembly 32. The rotating assembly 32 may be fixed on the lifting platform 22, and the rotating platform 31 may be connected to the rotating assembly 32 and may rotate relative to the rotating assembly 32.

[0043] Alternatively, as Figure 1-4 As shown, the control motor 4 can be drive-connected to the lifting platform 22 and the rotating platform 31 .

[0044] In the embodiment of the present application, the working process of the lifting and rotating platform system of the stereo garage can be as follows:

[0045] When the vehicle needs to park in or drive out of the stereo garage, the vehicle can drive into the lifting platform 22 and be located above the rotating platform 31 .

[0046] Combine Figure 1-5As shown, first, the control motor 4 can control the lifting platform 22 to rise, and can drive the rotating platform 31 to rise together with the vehicle until the lifting platform 22 is higher than the top ground of the foundation pit 100, and the distance h between the lifting platform 22 and the top ground of the foundation pit 100 reaches a first preset distance (for example, 300 mm). Then, the control motor 4 can determine the rotation direction of the rotating platform 31, and control the rotating platform 31 to rotate counterclockwise or clockwise relative to the rotating unit 32 based on the rotation direction to rotate a preset angle, driving the vehicle to adjust the direction of entry or exit. For example, when the rotation direction is to rotate to the left, that is, the vehicle needs to exit or enter to the left, the control motor 4 can control the rotating platform 31 to rotate 90 degrees counterclockwise relative to the rotating unit 32 based on the rotation direction. Alternatively, when the rotation direction is to rotate to the rear, that is, the vehicle needs to exit or enter backward, the control motor 4 can control the rotating platform 31 to rotate 180 degrees counterclockwise or clockwise relative to the rotating unit 32 based on the rotation direction. Afterwards, the control motor 4 can control the lifting platform 22 to descend, and can drive the rotating platform 31 to descend together, until the lifting platform 22 is at the same level as the vehicle's exit or entry ground, making it easier for the driver to drive the vehicle out of the stereo garage or into the parking space in the stereo garage. Figure 5 For example, the ground where the vehicle exits or enters is at the same level as the top ground of the foundation pit 100 .

[0047] It should be noted that the first preset distance and the preset angle can be set according to actual needs and are not limited in the embodiment of the present application.

[0048] In an embodiment of the present application, the lifting and rotating platform system of the multi-story parking garage can control the lifting and rotating platforms to be at the same level as the ground where the vehicle exits or enters, so that the lifting and rotating platforms are flush with the ground where the vehicle exits or enters, and can also control the rotation direction of the vehicle, thereby making it easier for the driver to park.

[0049] Optionally, combined Figure 1-3 As shown, the fixed sub-frame 1 may include two fixed sub-frames 11 and a top support platform 12. The two fixed sub-frames 11 may be located on either side of the foundation pit 100. The fixed sub-frame 11 may include a bottom support 111 and a fixed support 112. The bottom end of the bottom support 111 may be fixed to the bottom ground of the foundation pit 100, and the bottom end of the fixed support 112 may be fixed to the top of the bottom support 111. The top of the fixed support 112 may be located below the horizontal plane of the top ground of the foundation pit 100. This can ensure that the lifting platform 22 and the rotating platform 31 are flush with the top ground of the foundation pit 100 while supporting the lifting platform 22 and the rotating platform 31. Furthermore, this can facilitate parking for the driver.

[0050] Specifically, combined Figure 1-3As shown, the bottom bracket 111 and the fixing bracket 112 may be concave structures, the bottom ends of the bottom bracket 111 and the fixing bracket 112 are open ends, and the top ends of the bottom bracket 111 and the fixing bracket 112 are closed ends.

[0051] Specifically, combined Figure 1-3 As shown, the bottom end of the lifting guide column 21 can be fixed to the first side end of the fixed bracket 112 facing the side of the foundation pit 100. One side end of the top support platform 12 can be fixed to the second side end of the fixed bracket 112 away from the first side end. This can meet the requirements of the lifting platform 22 and the rotating platform 31 to be raised and lowered relative to the top ground of the foundation pit 100, and can meet the requirements of the lifting platform and the rotating platform being flush with different exit or entry grounds. Furthermore, it can facilitate the driver to park.

[0052] Optionally, combined Figure 1-3 As shown in Figure 8, the lifting guide column 21 may include a fixed guide column 211 and a movable component 212. The movable component 212 may be arranged in the fixed guide column 211 and may be lifted and lowered relative to the fixed guide column 211.

The suspension shaft 2122 may include a connecting rod 21221 and a U-shaped member 21222. One end of the connecting rod 21221 may be connected to the top structure of the multi-story parking garage via the fixed axis 2124, while the other end of the connecting rod 21221 may be fixedly connected to a pulley 2121. The U-shaped member 21222 may be fixed to the other end of the connecting rod 21221, with the open end of the U-shaped member 21222 facing the pulley 2121 connected to the connecting rod 21221. The ends of the pulley axis 2125 pass through the two pulleys 2121 and are fixedly connected to the ends of the open end of the U-shaped member 21222, forming a circular axis. The suspension column 2123 may be fixed in the middle of the circular axis. One side end of the lifting platform 22 can be fixedly connected to the suspension column 2123.

[0054] Optionally, combined Figure 1-8 As shown, the fixing guide column 211 can be fixed to the side end of the foundation pit 100 by the triangular bracket 200, and the guide column 211 can be stably fixed. Figure 8 As shown, the top frame of the triangular support 200 can be at the same water level as the top ground of the foundation pit 100.

[0055] In the embodiment of the present application, by cooperating with the crane to stretch the fixed axis 2124, the lifting platform can be supported for lifting and lowering, and the purpose of stabilizing the lifting platform can be achieved when the lifting platform stops lifting.

[0056] Optionally, combined Figure 1-3 As shown, the lifting assembly 2 further includes a plurality of lifting rails 23 and a plurality of lifting guide sleeves 24, respectively located on either side of the lifting platform 22. The plurality of lifting guide sleeves 24 can be inserted into the plurality of lifting rails 23 in a one-to-one correspondence, and the lifting guide sleeves 24 can be raised and lowered relative to the lifting rails 23. The lifting rails 23 can be positioned outside the second side end of the fixed bracket 112. One end of the lifting rail 23 can pass through the top bracket platform 12 and be fixedly connected to the top end of the bottom bracket 111. One end of the lifting guide sleeve 23 can be fixedly connected to the bottom end of the lifting platform 22.

[0057] In the embodiment of the present application, by providing a lifting rail column and a lifting guide sleeve, the lifting platform can be easily lifted and lowered, and the stability of the lifting platform can be enhanced when the lifting platform stops lifting.

[0058] Optionally, combined Figure 1-3 As shown, the fixed sub-assembly 11 further includes a support column 113. The support column 113 can be located between the fixed bracket 112 and the lifting rail column 23. One end of the support column 113 can be fixed to the top of the bottom bracket 111, and the other end of the support column 113 can be fixed to the bottom of the top bracket platform 12. The other end of the lifting guide sleeve 24 can be connected to the support column 113 and can be raised and lowered relative to the support column 113.

[0059] In the embodiment of the present application, by being arranged on the support column, it is possible to support the top bracket platform while also enhancing the stability of the lifting platform when the lifting platform stops lifting.

[0060] Specifically, combined Figure 1-3 As shown, the outer side of the lifting rail column 23 can be provided with a tooth pattern, and the inner side of the lifting guide sleeve 24 can be provided with a tooth pattern. The lifting rail column 23 and the lifting guide sleeve 24 can be connected by the tooth pattern.

[0061] In the embodiment of the present application, by providing teeth on the outer side of the lifting rail column and the inner side of the lifting guide sleeve, the stability of the lifting platform can be further enhanced when the lifting platform stops lifting while supporting the lifting of the lifting platform.

[0062] Specifically, combined Figure 1-3 As shown, the lifting guide sleeve 24 can be an L-shaped structure to facilitate connection with the support column 113.

[0063] Optionally, combined Figure 1-3As shown, the control motor 4 may include a lifting control motor 41 and a rotation control motor 42. The lifting control motor 41 may be drivably connected to the lifting platform 22 to control the lifting of the lifting platform 22.

[0064] Specifically, combined Figure 1-7 As shown, the lift control motor 41 includes a first drive motor 411 and a lift support arm 412. One end of the first drive motor 411 can be fixed to the fixed bracket 112, and the other end of the first drive motor 411 can be drivingly connected to one end of the lift support arm 412. The other end of the lift support arm 412 can pass through the lift guide sleeve 24 and be drivingly connected to the lift rail 23. Specifically, the lift support arm 412 can be a retractable structure.

[0065] In the embodiment of the present application, the first drive motor drives the lifting support arm to move up and down relative to the lifting rail column, which can drive the lifting guide sleeve to move up and down relative to the lifting rail column, thereby supporting the lifting platform and the rotating platform to move up and down.

[0066] Specifically, combined Figure 1-6 As shown, the rotation control motor 42 may include a second drive motor 421 and a rotation support arm 422. One end of the second drive motor 421 may be fixed to the top support platform 12, and the other end of the second drive motor 421 may be drivingly connected to one end of the rotation support arm 422. The other end of the rotation support arm 422 may be fixedly connected to the rotation platform 31. Specifically, the rotation support arm 422 may be a retractable, rotating structure.

[0067] In the embodiment of the present application, the first drive motor drives the rotating support arm to lift and lower relative to the top support platform, and drives the rotating support arm to rotate relative to the lifting platform. This can support the rotating platform to lift and lower together with the lifting platform, and can also support the rotating platform to adjust its direction, so that the rotating platform can be flush with the ground when the vehicle is exiting or entering, and the rotation direction of the vehicle can also be controlled.

[0068] Specifically, combined Figure 1-6 As shown, the rotating platform 31 may be provided with a plurality of latches 311, and the rotating assembly 32 may be provided with a plurality of buckles 321. The rotating platform 31 and the rotating assembly 32 may be connected via at least some of the plurality of latches 311 and at least some of the buckles 321, so as to support the rotating platform 31 to rotate at any angle relative to the rotating assembly 32.
