Description

Technical Field

[0001] The present invention belongs to the technical field of stereo garages, and specifically relates to a novel vertical lifting stereo garage and an operation method thereof. Background Art

[0002] With rapid urbanization and the continued rise in car ownership, parking has become a common problem in many large and medium-sized cities. Traditional ground parking lots occupy large areas, making them inadequate in land-scarce urban cores. It is against this backdrop that multi-story parking garages have emerged. By vertically stacking parking garages, they expand the space originally reserved for one car into a three-dimensional space capable of parking two or more vehicles, cleverly resolving the conflict between scarce land and surging parking demand.

[0003] Currently, there are various types of stereo garages on the market, including but not limited to vertical lift, lift and transverse movement, vertical circulation, plane movement, and aisle stacking. Vertical lift stereo garages, commonly known as tower garages, can be divided into the following types based on how vehicles entering the tower garage are placed in the empty spaces within the tower garage: The first type is the car plate exchange type. The vehicle-carrying device on the lifting mechanism is the car plate. The vehicle to be stored enters the tower and is parked on the lifting mechanism's car plate. The lifting mechanism then rises to a level with an empty space. A controllable robotic arm mounted on the lifting mechanism then moves the car plate horizontally to the empty space. The robotic arm then retracts the arm back to the lifting mechanism, completing the task of placing the vehicle in the empty space. The lifting mechanism then descends to the next level closest to the ground. The robotic arm on the lifting mechanism then moves the empty car plate from that level horizontally onto the lifting mechanism, which then lowers it to the ground, completing the parking garage entrance and exit standby mode.

[0004] The second type is the comb-tooth exchange type. The load-bearing device fixed to the lifting mechanism is comb teeth A. The vehicle to be parked enters the garage entrance, and its four tires stop on the lifting mechanism's comb teeth A. The lifting mechanism then rises to the nearest level with an empty parking space. This empty space is equipped with a comb-tooth parking plate B that can be moved horizontally from the parking space to the elevator shaft. After the lifting mechanism rises to its upper position, comb teeth B are moved horizontally to the bottom of the lifting mechanism via the transverse mechanism. The lifting mechanism then descends, and the vehicle parked on the lifting mechanism's comb teeth A is blocked by comb teeth B. The lifting mechanism's comb teeth A then cross comb teeth B in an interlaced manner, thus completing the process of exchanging the vehicle on the lifting mechanism's comb teeth A to the parking space's comb teeth B. The lifting mechanism then lowers to the ground.

[0005] The third type is the roller-exchange type. The lifting mechanism's carrier is a rolling roller assembly A. A vehicle to be stored enters the garage entrance, with its four wheels resting on the lifting mechanism's roller assembly A. The lifting system then ascends to the nearest available parking space, where a parking structure equipped with a rolling roller assembly B is located. Once the lifting mechanism's roller assembly A is parallel to the roller assembly B of the parking structure above the empty space, the rollers on roller assemblies A and B rotate in the same direction, moving the vehicle on roller assembly A onto roller assembly B of the parking structure. The lifting mechanism then descends to the ground.

[0006] The fourth type, the pulley exchange type, is similar to the roller exchange type. The lifting mechanism's carrier is a rotating pulley A. The vehicle to be stored enters the garage entrance, with its four tires resting on the belt of pulley A. The lifting mechanism then ascends to the nearest available level, where a rotating pulley B is located. Once the lifting mechanism is parallel to pulley B in the empty space, pulleys A and B rotate in the same direction, moving the vehicle on pulley A's belt onto pulley B's belt. The lifting mechanism then descends to the ground.

[0007] However, plate-exchange turrets rely on a robotic arm to support the vehicle's weight during the exchange process, while comb-exchange turrets rely on their comb teeth throughout the entire process, limiting the weight of parked vehicles. Comb-exchange turrets are particularly prone to deformation and interference during operation, impacting equipment operation. Roller-exchange and pulley-exchange turrets utilize rollers or pulleys to exchange vehicles between the parked carrier and the lifting mechanism, requiring high horizontal alignment of the two rollers or pulleys. During use, the lifting mechanism often experiences leveling deviations due to different load-bearing conditions, preventing the two rollers or pulleys from aligning horizontally, impacting equipment operation.

[0008] In addition, the patent document with publication number CN118167104A discloses a hook-exchange multi-layer lifting and transverse movement system. The lifting mechanism of this system includes a front hook assembly for hooking the front hanging hole of the vehicle board and a rear hook assembly for hooking the rear hanging hole of the vehicle board. The front and rear hook assemblies are driven by an electric assembly to synchronously reciprocate and lift. The vehicle board is also provided with a transfer hanging hole, and the transverse movement frame of the multi-layer lifting and transverse movement system is provided with an anti-fall hook for disengaging from the transfer hanging hole when the vehicle board is raised or lowered, or for hooking with the transfer hanging hole after the vehicle board is raised into place. When in use, each column of the multi-layer lifting and transverse movement system is equipped with a set of this lifting mechanism, which realizes the exchange of the lifting state of the vehicle board and the state of parking in the corresponding storage space, which can reduce the number of lifting mechanisms of the entire machine and save costs. For example, a parking system with six layers and five columns only needs to be installed with five sets of this lifting mechanism, with a total parking capacity of 25 vehicles. This lifting mechanism is simpler than the comb-tooth lifting system, maintains the traditional simpler transverse movement system, and has a fast hook exchange action.

[0009] However, the transverse frame of the above system uses anti-fall hooks to hang the loading plate and vehicles, which has low reliability and safety; each column is equipped with a lifting mechanism, which is not conducive to cost control; when the columns on the same level are full of vehicles, the vehicles can only be taken out in order from bottom to top, and it is impossible to bypass the vehicles on the lower level to take the vehicles on the upper level first; the hooks of the front and rear hook assemblies hook the loading plate from bottom to top and are always located between the loading plate and the ground. When the loading plate falls to the ground, the front and rear hook assemblies cannot be separated from the loading plate. If the driver operates improperly or the vehicle size is close to the design limit, the vehicle and the electric component may be scratched, which will not only damage the vehicle surface, affecting the appearance and service life, but also may cause wear or breakage of the electric component, thereby affecting the stability and safety of the entire system. Summary of the Invention

[0010] This solution aims to overcome at least one defect in the existing technology and provide a new vertical lift type stereo garage operation method to solve the problems of low load capacity and high operation requirements of existing vertical lift type stereo garages.

[0011] In order to solve the above technical problems, the following technical solutions are adopted: First, a novel operating method for a vertical lift multi-story parking garage is proposed. The multi-story garage features an elevator shaft and parking areas located on one or both sides of the shaft. The elevator shaft is equipped with a lifting frame for lifting and lowering a loading platform. The parking area has multi-story parking spaces, each equipped with a transverse frame for supporting and horizontally moving a loading platform. The loading platform is used to carry vehicles. The operating method includes both retracting and releasing the platform.

[0012] The board retracting action includes the following steps: lowering the lifting frame until the lifting frame is close to the loading plate, establishing a connection between the lifting frame and the loading plate, raising the lifting frame until the loading plate is completely located on the transverse frame of the target parking space, moving the transverse frame in the target parking space until the transverse frame completely enters the lifting channel, lowering the lifting frame until the loading plate falls on the transverse frame, releasing the connection between the lifting frame and the loading plate, raising the lifting frame until the lifting frame is completely separated from the loading plate and is completely located on the loading plate or the vehicle, and moving the transverse frame until the transverse frame and the loading plate are completely returned to the target parking space.

[0013] The board placing action includes the following steps: confirming or raising the lifting frame until the lifting frame is completely located on the vehicle loading plate or vehicle in the target parking space, moving the transverse frame in the target parking space until the transverse frame and the vehicle loading plate are completely entered into the lifting channel, lowering the lifting frame until the lifting frame is close to the vehicle loading plate, establishing a connection between the lifting frame and the vehicle loading plate, raising the lifting frame until the vehicle loading plate is completely separated from the transverse frame and is completely located on the transverse frame, moving the transverse frame until the transverse frame is completely returned to the target parking space, lowering the lifting frame until the vehicle loading plate is lowered into place, releasing the connection between the lifting frame and the vehicle loading plate, and raising the lifting frame to allow the vehicle to enter or leave the vehicle loading plate.

[0014] During the board folding and board releasing actions, if there is a vehicle parked on the loading board, in the step of lowering the lifting frame until the lifting frame is close to the loading board, the lifting frame passes over the vehicle until it is close to the loading board during the lowering process, and in the step of raising the lifting frame until the lifting frame is completely separated from the loading board and completely located on the loading board or the vehicle, and in the step of raising the lifting frame so that the vehicle can enter or leave the loading board, the lifting frame is separated from the vehicle during the raising process until the lifting frame is completely located above the vehicle.

[0015] In this solution, the lifting frame connects to the vehicle loading plate from top to bottom within the lifting channel and disconnects from the loading plate from bottom to top. This switching of connections allows the loading plate to be transferred and exchanged between the transverse frame and the ground (in a broad sense), a completely different exchange method from existing vertical lift parking garages. During the lifting process, the vehicle is carried by the loading plate, which can move between the ground and the transverse frame, rather than by a comb or other device fixed to the lifting frame in a cantilevered manner. The loading plate moves between the ground and the transverse frame through the coordinated operation of the lifting frame and the transverse frame, rather than through grasping and transverse movement using a device such as a robotic arm. This allows the loading plate to carry heavier vehicles, significantly relaxing the load limit. The parking process is that during the coordinated operation of the lifting frame and the transverse frame, the lifting frame first rises vertically to the oblique upper side of the transverse frame, and then after the transverse frame moves horizontally to the bottom of the lifting frame, it slightly lowers with the vehicle loading plate and the vehicle. After the vehicle loading plate and the vehicle are settled on the transverse frame, it is disconnected from the vehicle loading plate and slightly rises alone to complete the transfer and exchange. This process does not require the two parts of the roller / pulley to be horizontally aligned like the roller exchange or pulley exchange type three-dimensional parking garage, so there is no need to worry about the exchange being blocked due to operation deviation.

[0016] Compared with existing multi-story lifting and transverse moving stereoscopic parking garages, this solution makes the lifting channel relatively independent from the parking area through the operation method. The lifting channel is only for the loading plate and vehicles to perform lifting and lowering movements. Except for the loading plate waiting for vehicles to enter on the bottom floor, the loading plate and vehicles only stay in the parking area before and after lifting and will not occupy the lifting channel. This relative independence ensures that the lifting channel always remains unobstructed, which in turn ensures that the above-mentioned operation method can be implemented. The relative independence of the lifting channel and the parking area and the implementation of the above-mentioned operation method allow the loading plate to fall from top to bottom on the transverse moving frame, and the transverse moving frame can support the loading plate and the vehicle it carries from bottom to top, so that the loading plate, especially the loading plate carrying vehicles, can be stably parked in high-rise parking spaces. Compared with the solution where the loading plate is hung on the transverse moving frame, the reliability and safety are significantly improved. This operating method utilizes a single lifting device (elevation channel and its lifting frame, etc.) to raise and lower vehicle loading plates and vehicles (if any) in multiple high-rise parking spaces. Compared to lift-and-slide garages that require a lifting device for each parking space or row, this method offers a simpler structure and lowers manufacturing costs. The lifting device connects the loading plates via the lifting frame, improving the synchronization of connection actions at each connection point, making the connection process smoother and the established connections more stable, reliable, and secure. This operating method allows the loading plates and vehicles to be removed from any parking space at any time, eliminating the need for sequential retrieval, significantly enhancing vehicle retrieval flexibility.

[0017] There is a parking and retrieval platform at the bottom of the lifting channel. When there is an empty loading plate in the stereo garage (that is, before all the loading plates in the stereo garage are full of vehicles), there will only be one empty loading plate on the parking and retrieval platform before and after performing all actions, so that vehicles outside can enter at any time, and vehicles inside can land and leave at any time.

[0018] The step of lowering the lifting frame until the vehicle loading plate is lowered into place in the plate placing action is specifically: lowering the lifting frame until the vehicle loading plate is settled on the vehicle storage and retrieval platform or the vehicle loading plate on the vehicle storage and retrieval platform.

[0019] When parking a vehicle, the board retracting action is executed. After parking, if there are no loading pallets on the parking and retrieval platform, the board placement action is executed, and any loading pallet, either empty or loaded with a vehicle to be retrieved, is placed on the parking and retrieval platform, ensuring that a single empty loading pallet is reserved on the parking and retrieval platform. When retrieving a vehicle, the board placement action is reversed. After retrieving a vehicle, if there are two loading pallets on the parking and retrieval platform, the board retracting action is executed, and the upper loading pallet is retracted to the parking space with the missing pallet, ensuring that a single empty loading pallet is reserved on the parking and retrieval platform.

[0020] If parking and retrieving occur consecutively in the order of storage first and retrieval later, the loading plate on the parking and retrieval platform where the vehicle to be parked has entered will be retracted first, and then the loading plate on the parking area where the vehicle to be retrieved is placed will be lowered. No further actions need to be performed between or after the two actions, thus ensuring that there is still a single empty loading plate on the parking and retrieval platform after the above actions are completed.

[0021] If parking and retrieving occur consecutively in the order of retrieving first and then storing, the loading plate with the vehicle to be retrieved in the parking area will be lowered first. After the vehicle to be retrieved leaves and the vehicle to be stored enters, the loading plate with the vehicle to be stored on the parking and retrieval platform will be retracted. There is no need to perform further actions before or after the above two actions, which can ensure that there is still a single empty loading plate on the parking and retrieval platform after the above actions are completed.

[0022] If a loading plate is present on the parking platform before the vehicle is retrieved, the loading plate on the parking platform is lowered and the loading plate carrying the vehicle in the parking area is lowered. After the vehicle is retrieved, the upper loading plate on the parking platform is retracted and the lower loading plate on the parking platform is raised. Lowering the lower loading plate helps reduce the height difference between the upper loading plate and the parking platform surface, making it easier for vehicles to enter or exit the loading plate.

[0023] The steps of confirming or raising the lifting frame until the lifting frame is completely located on the loading plate or vehicle of a parking space in the board placing action are specifically: judging whether the lifting frame is completely located on the loading plate or vehicle of a parking space; if not, raising the lifting frame until the lifting frame is completely located on the loading plate or vehicle of a parking space.

[0024] Secondly, a novel vertical lift type multi-story parking garage is proposed. This multi-story parking garage utilizes the aforementioned operating method. The structure comprises a lift passage and parking areas located on one or both sides of the lift passage. The lift passage is equipped with a lifting frame for lifting and lowering a vehicle loading platform and a first drive mechanism for driving the lifting frame. The parking area comprises multi-story parking spaces, each of which is equipped with a transverse frame for carrying a vehicle loading platform, transverse guide rails spanning the parking area and the lift passage, and a second drive mechanism for driving the transverse frame to slide along the transverse guide rails. The vehicle loading platform is used to carry vehicles. The lifting frame allows the vehicle loading platform to connect and disconnect with it, and the transverse frame allows the vehicle loading platform to settle on it.

[0025] The connection between the lifting frame and the vehicle loading platform is established and released via a locking mechanism, which is located on either the lifting frame or the vehicle loading platform. Compared to having the locking mechanism fixed to the vehicle loading platform, having it fixed to the lifting frame better protects the locking mechanism from vehicle damage or collisions, thereby extending the locking mechanism's service life and reducing the frequency of replacement required due to vehicle damage or collisions. This also reduces the maintenance burden and cost of the multi-story parking garage and improves the stability and reliability of the lifting system.

[0026] The locking mechanism can have various structural forms, one of which includes a rotating shaft, a lock button, a transmission assembly, and a drive component. The drive component is in transmission connection with the transmission assembly, which is in transmission connection with a pin shaft. The lower end of the rotating shaft is fixedly connected to the lock button. The transmission assembly drives the rotating shaft and the lock button to rotate under the drive component. The vehicle loading plate or lifting frame is provided with a lock hole. The lock hole allows the lock button to be inserted or removed when it is rotated to a first azimuth angle, and prohibits the lock button from being inserted or removed when it is rotated to a second azimuth angle by locking. The connection established by the locking method does not rely on power maintenance (the drive component can be powered off after locking). Even if the system loses power or malfunctions, the connection will not be accidentally disconnected, greatly improving the safety of the vehicle loading plate during lifting and parking. During the locking / unlocking process, the locking mechanism only needs to complete the task of rotating the lock button, which is conducive to achieving fast and reliable locking and unlocking cycles, improving the operating efficiency of the garage. The locking / unlocking process does not require additional horizontal movement space, which is very suitable for application scenarios such as multi-story parking garages with extremely limited space.

[0027] Compared with the existing technology, this solution has the following beneficial effects: the lifting frame of this solution establishes a connection with the vehicle loading plate from top to bottom in the lifting channel and disconnects from the vehicle loading plate from bottom to top. Through this connection switching, the transfer and exchange of the vehicle loading plate between the transverse frame and the ground (in a broad sense) is realized. This exchange method is completely different from the exchange method of the existing vertical lifting type stereo garage. Compared with the existing vertical lifting type stereo garage, it is conducive to relaxing the load limit and reducing the operation requirements. Compared with the existing multi-layer lifting and transverse moving type stereo garage, it is conducive to reducing the number of lifting mechanisms, reducing equipment costs, improving load-bearing capacity, improving equipment reliability, and improving the flexibility of storing and retrieving vehicles.

DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the present solution, the present solution is further described in detail below with reference to specific embodiments.

[0041] Figure 1The diagram illustrates a possible new vertical lift type multi-story parking garage for parking vehicles. The multi-story parking garage includes a main frame 100, a lifting frame 310, a transverse frame 410, and a vehicle loading plate 200. The main frame 100 is constructed from multiple columns and multiple beams, forming a lifting passage 110 and a parking area 120 within the main frame 100. The parking area 120 is located on one or both sides of the lifting passage 110, such as the left side, right side, or both sides. The parking area 120 is provided with multi-story parking spaces 121, such as n floors. If parking area 120 is provided on one side, the space that originally could only accommodate two vehicles on the ground can now accommodate n vehicles. If parking areas 120 are provided on both sides, the space that originally could only accommodate three vehicles on the ground can now accommodate 2n vehicles. The vehicle is carried by the vehicle loading plate 200, and the lifting channel 110 is provided with a lifting frame 310 for driving the vehicle loading plate 200 to rise and fall, so that the vehicle and the vehicle loading plate 200 can rise from the bottom of the stereo garage to each floor, and can also be lowered from each floor of the stereo garage to the bottom. Each parking space 121 is provided with a transverse frame 410 for carrying the vehicle loading plate 200 and driving the vehicle loading plate 200 to move horizontally, so that the vehicle and the vehicle loading plate 200 can stay on a certain floor of the stereo garage and release the lifting frame 310.

[0042] The operation method of the new vertical lift type multi-story parking garage includes a plate-retracting action and a plate-releasing action. The plate-retracting action is used to retract the vehicle-carrying plate 200 at the bottom of the lifting channel 110 into any empty parking space 121 (the parking space 121 during the plate-retracting action can be referred to as the target parking space 121), so that vehicles that have just entered the multi-story parking garage can park in the parking space 121. It can also prevent excessive vehicle-carrying plates 200 from being stacked at the bottom of the lifting channel 110, affecting the entry or exit of vehicles. The plate-releasing action is used to release the vehicle-carrying plate 200 in any parking space 121 (the parking space 121 during the plate-releasing action can be referred to as the target parking space 121) to the bottom of the lifting channel 110, so that vehicles parked on the vehicle-carrying plate 200 can leave and vehicles outside the multi-story parking garage can enter.

[0043] like Figure 2 As shown, the plate collecting action includes steps S11 to S18.

[0044] S11. Lower the lifting frame 310 until the lifting frame 310 is close to the vehicle plate 200, as Figure 6 The hollow portion of the lifting frame 310 allows vehicles to pass through, allowing the lifting frame 310 to completely avoid vehicles parked on the vehicle loading platform 200. Therefore, regardless of whether the vehicle loading platform 200 is loaded, the lifting frame 310 can be unobstructedly close to the vehicle loading platform 200, thereby establishing a connection between the lifting frame 310 and the vehicle loading platform 200. If a vehicle is loaded on the vehicle loading platform 200, the lifting frame 310 will pass over the vehicle during the lowering process until it is close to the vehicle loading platform 200. When close to the vehicle loading platform 200, the lifting frame 310 will be placed on the outside of the bottom of the vehicle.

[0045] S12. Establish a connection between the lifting frame 310 and the vehicle loading plate 200. After the connection is established, the vehicle loading plate 200 will follow the lifting frame 310 in the lifting and lowering movement. If the vehicle loading plate 200 is carrying a vehicle, the vehicle will also follow the lifting frame 310 in the lifting and lowering movement.

[0046] S13. Raise the lifting frame 310 until the vehicle loading plate 200 is completely located above the target parking space 121 of the lateral frame 410, as Figure 7 Regardless of whether the loading plate 200 is carrying a vehicle, as long as the loading plate 200 is completely above the transverse frame 410, the loading plate 200 has a chance to land on the transverse frame 410 that is moved from the target parking space 121 into the lifting channel 110. When the loading plate 200 is completely above the transverse frame 410, the vertical distance between the lifting frame 310 and the transverse frame 410 is smaller than the vertical distance between the top of the target parking space 121 and the transverse frame 410. To facilitate controlling the rising position of the lifting frame 310, the lifting frame 310 can be placed completely above the top of the target parking space 121.

[0047] S14 moves the target parking space 121 in the lateral frame 410 until the lateral frame 410 completely enters the lifting channel 110, as Figure 8 As long as the traverse frame 410 completely enters the lifting channel 110 , the vehicle loading plate 200 will gradually settle on the traverse frame 410 during the descent process, and the gravity of the vehicle loading plate 200 and even the vehicle borne by the lifting frame 310 will be gradually transferred to the traverse frame 410 .

[0048] S15. Lower the lifting frame 310 until the vehicle loading plate 200 lands on the transverse frame 410. After the vehicle loading plate 200 lands, the lifting frame 310 no longer needs to bear the gravity from the vehicle loading plate 200 or even the vehicle, so that the lifting frame 310 and the vehicle loading plate 200 can be disconnected.

[0049] S16. Release the connection between the lifting frame 310 and the vehicle loading plate 200. After the connection is released, no matter whether the lifting frame 310 is raised or lowered, the vehicle loading plate 200 will remain stationary on the transverse moving frame 410 supporting it.

[0050] S17. Raise the lifting frame 310 until the lifting frame 310 is completely separated from the vehicle loading plate 200 and is completely located on the vehicle loading plate 200 or the vehicle, as Figure 9. The hollow part of the lifting frame 310 can allow vehicles to pass through, so that the lifting frame 310 can completely avoid the vehicles parked on the loading plate 200. Therefore, regardless of whether the loading plate 200 is carrying a vehicle, the lifting frame 310 can move away from the loading plate 200 unimpeded. If there is a vehicle on the loading plate 200, the lifting frame 310 will be separated from the vehicle during the lifting process until the lifting frame 310 is completely above the vehicle (that is, the lowest point of the lifting frame 310 is above the highest point of the vehicle). If the loading plate 200 is unloaded, it is sufficient to ensure that the lifting frame 310 is completely above the loading plate 200 (that is, the lowest point of the lifting frame 310 is above the highest point of the loading plate 200), so that the transverse frame 410 carrying the loading plate 200 or even the vehicle can be moved back to the target parking space 121 unimpeded. When the lifting frame 310 is just completely located above the vehicle loading plate 200, the vertical distance between the lifting frame 310 and the vehicle loading plate 200 is smaller than the vertical distance between the top of the target parking space 121 and the vehicle loading plate 200; when the lifting frame 310 is just completely located above the vehicle, the vertical distance between the lifting frame 310 and the vehicle is also smaller than the vertical distance between the top of the target parking space 121 and the vehicle; in order to facilitate the control of the rising position of the lifting frame 310, regardless of whether the vehicle loading plate 200 is carrying a vehicle, the lifting frame 310 can be completely located above the top of the target parking space 121.

[0051] S18. Move the lateral frame 410 until the lateral frame 410 together with the vehicle loading plate 200 completely returns to the target parking space 121, as Figure 10 If the loading plate 200 is empty, the transverse moving frame 410 only sends the loading plate 200 to the target parking space 121. If the loading plate 200 is loaded with a vehicle, the transverse moving frame 410 sends the loading plate 200 and the vehicle to the target parking space 121, so that the loading plate 200 and the vehicle can be parked in the parking space 121, while ensuring that the lifting channel 110 is unobstructed, clearing obstacles for the next loading or unloading action.

[0052] like Figure 3 As shown, the board placing action includes steps S21 to S29.

[0053] S21 confirm or raise the lifting frame 310 until the lifting frame 310 is completely located on the target parking space 121 of the vehicle loading plate 200 or vehicle, such as Figure 10If the loading plate 200 in the target parking space 121 is empty, it is sufficient to ensure that the lifting frame 310 is completely above the loading plate 200 (i.e., the lowest point of the lifting frame 310 is above the highest point of the loading plate 200). If the loading plate 200 in the target parking space 121 is loaded with a vehicle, it is necessary to ensure that the lifting frame 310 is completely above the vehicle (i.e., the lowest point of the lifting frame 310 is above the highest point of the vehicle), so that the transverse movement frame 410 carrying the loading plate 200 and even the vehicle in the parking space 121 can move into the lifting channel 110 unimpeded. When the lifting frame 310 is just completely located above the vehicle loading plate 200, the vertical distance between the lifting frame 310 and the vehicle loading plate 200 is smaller than the vertical distance between the top of the target parking space 121 and the vehicle loading plate 200; when the lifting frame 310 is just completely located above the vehicle, the vertical distance between the lifting frame 310 and the vehicle is also smaller than the vertical distance between the top of the target parking space 121 and the vehicle; in order to facilitate the control of the rising position of the lifting frame 310, regardless of whether the vehicle loading plate 200 is carrying a vehicle, the lifting frame 310 can be completely located above the top of the target parking space 121.

[0054] Specifically, this step may include: S211. Determine whether the lifting frame 310 is completely located on the vehicle loading plate 200 or the vehicle in a parking space 121. If yes, jump to step S22; if not, execute step S212.

[0055] S212. Raise the lifting frame 310 until the lifting frame 310 is completely located on the vehicle loading plate 200 or the vehicle in a parking space 121.

[0056] S22 moves the target parking space 121 in the lateral frame 410 until the lateral frame 410 together with the vehicle loading plate 200 completely enters the lifting channel 110, such as Figure 9 If the vehicle loading plate 200 is empty, the transverse frame 410 only delivers the vehicle loading plate 200 into the lifting channel 110 . If the vehicle loading plate 200 is loaded with a vehicle, the transverse frame 410 delivers the vehicle loading plate 200 and the vehicle into the lifting channel 110 .

[0057] S23. Lower the lifting frame 310 until the lifting frame 310 is close to the vehicle plate 200, as Figure 8 The lifting frame 310 is a frame structure with a hollow portion for vehicles to pass through, allowing the lifting frame 310 to completely avoid vehicles parked on the vehicle loading platform 200. Therefore, regardless of whether the vehicle is loaded on the vehicle loading platform 200, the lifting frame 310 can be unobstructedly close to the vehicle loading platform 200, thereby establishing a connection between the lifting frame 310 and the vehicle loading platform 200. If a vehicle is loaded on the vehicle loading platform 200, the lifting frame 310 will pass over the vehicle during the lowering process until it is close to the vehicle loading platform 200. When close to the vehicle loading platform 200, the lifting frame 310 will be placed on the outside of the bottom of the vehicle.

[0058] S24. Establish a connection between the lifting frame 310 and the vehicle loading plate 200. After the connection is established, the vehicle loading plate 200 will follow the lifting frame 310 in the lifting and lowering movement. If the vehicle loading plate 200 is carrying a vehicle, the vehicle will also follow the lifting frame 310 in the lifting and lowering movement.

[0059] S25. Raise the lifting frame 310 until the loading plate 200 is completely separated from the traversing frame 410 and completely positioned above the traversing frame 410. Regardless of whether the loading plate 200 is carrying a vehicle, as long as the loading plate 200 is completely separated from the traversing frame 410 and completely positioned above the traversing frame 410, the traversing frame 410 can move back to the target parking space 121 unimpeded. When the loading plate 200 is completely separated from the traversing frame 410 and completely positioned above the traversing frame 410, the vertical distance between the lifting frame 310 and the traversing frame 410 is less than the vertical distance between the top of the target parking space 121 and the traversing frame 410. To facilitate control of the lifting position of the lifting frame 310, the lifting frame 310 can be positioned completely above the top of the target parking space 121.

[0060] S26. Move the lateral frame 410 until the lateral frame 410 completely returns to the target parking space 121, as Figure 7 As long as the lateral movement frame 410 is completely returned to the target parking space 121, the lifting channel 110 is restored to be unobstructed, and the lifting frame 310 can be raised and lowered in the lifting channel 110 without obstruction.

[0061] S27. Lower the lifting frame 310 until the vehicle plate 200 drops into place, as Figure 6 The vehicle entrance and exit are usually located on the ground floor of a multi-story parking garage. The loading platform 200 is considered to have been lowered into position when it reaches the bottom floor and is supported by the ground or other surface below. During the descent, the weight of the loading platform 200, and even the vehicle, borne by the lifting frame 310 is gradually transferred to the ground or other surface. After lowering into position, the lifting frame 310 no longer needs to bear the weight of the loading platform 200 or even the vehicle, allowing the lifting frame 310 to be disconnected from the loading platform 200.

[0062] S28. Release the connection between the lifting frame 310 and the vehicle loading plate 200. After the connection is released, regardless of whether the lifting frame 310 is raised or lowered, the vehicle loading plate 200 will remain stationary on the ground or other surface supporting it.

[0063] S29. Raise the lifting frame 310 so that the vehicle enters or leaves the vehicle loading plate 200, as Figure 5. The hollow part of the lifting frame 310 can be passed by the vehicle, so that the lifting frame 310 can completely avoid the vehicle parked on the vehicle loading plate 200. Therefore, regardless of whether the vehicle loading plate 200 is loaded with a vehicle, the lifting frame 310 can move away from the vehicle loading plate 200 unimpeded until it is completely located above the vehicle, so that the vehicle originally parked on the vehicle loading plate 200 can leave unimpeded, and the vehicles outside the stereo garage can enter unimpeded. If there is a vehicle on the vehicle loading plate 200, the lifting frame 310 will be separated from the vehicle during the lifting process until the lifting frame 310 is completely located above the vehicle. When the lifting frame 310 is just completely located above the vehicle, the vertical distance between the lifting frame 310 and the vehicle is smaller than the vertical distance between the top of the bottom parking space 121 of the stereo garage and the vehicle. In order to facilitate the control of the rising position of the lifting frame 310, the lifting frame 310 can be completely located above the top of the bottom parking space 121.

[0064] In the above-described operating method, the lifting frame 310 connects to the vehicle loading plate 200 from top to bottom and disconnects from the vehicle loading plate 200 from bottom to top within the lifting channel 110. This switching of connections allows the vehicle loading plate 200 to be transferred and exchanged between the traversing frame 410 and the ground (broadly speaking, including the ground and other surfaces at the bottom of the multi-story parking garage that can support the vehicle loading plate). This exchange method is completely different from the exchange method used in existing vertical lift multi-story parking garages. During the lifting process, the vehicle is supported by the vehicle loading plate 200, which can move between the ground and the traversing frame 410, rather than by a comb or other device fixed to the lifting frame 310 in a cantilevered manner. The movement of the vehicle loading plate 200 between the ground and the traversing frame 410 is achieved through the coordinated operation of the lifting frame 310 and the traversing frame 410, rather than by grasping and moving the vehicle loading plate 200 using a mechanical arm or other device. Therefore, the vehicle loading plate 200 can carry heavier vehicles and significantly relax the load limit. During the coordinated operation of the lifting frame 310 and the transverse frame 410, the lifting frame 310 first rises vertically to the upper side of the transverse frame 410, and then, after the transverse frame 410 moves horizontally to the bottom of the lifting frame 310, it slightly lowers with the vehicle loading plate 200 and the vehicle. After the vehicle loading plate 200 and the vehicle settle on the transverse frame 410, it is disconnected from the vehicle loading plate 200 and slightly rises alone, thereby completing the transfer and exchange. This process does not require the two parts of the roller / pulley to be horizontally aligned like the roller exchange or pulley exchange type multi-story parking garage, so there is no need to worry about the exchange being blocked due to operation deviation.

[0065] The above-mentioned operating method makes the lifting channel 110 relatively independent from the parking area 120. The lifting channel 110 is only used for the vehicle loading plate 200 and the vehicle to be lifted and lowered. Except for the vehicle loading plate 200 waiting for the vehicle to enter on the bottom floor, the vehicle loading plate 200 and the vehicle only stay in the parking area 120 before and after the lifting and lowering movement, and do not occupy the lifting channel 110. This relative independence ensures that the lifting channel 110 is always unobstructed, which in turn ensures that the above-mentioned operating method can be implemented. The relative independence of the lifting channel 110 and the parking area 120 and the implementation of the above-mentioned operating method allow the vehicle loading plate 200 to be placed from top to bottom on the transverse frame 410. The transverse frame 410 can support the vehicle loading plate 200 and the vehicle it carries from bottom to top, so that the vehicle loading plate 200, especially the vehicle loading plate 200 carrying a vehicle, can be stably parked in the high-rise parking space 121. Compared with the solution where the vehicle loading plate 200 is suspended from the transverse frame 410, the reliability and safety are significantly improved. This operating method uses a single set of lifting equipment (such as the lifting channel 110 and its lifting frame 310) to raise and lower the loading plates 200 and vehicles (if any) in multiple high-rise parking spaces 121. Compared to lifting and transverse parking garages that require a lifting device for each parking space 121 row, this method offers a simpler structure and lowers manufacturing costs. The lifting equipment connects the loading plates 200 via the lifting frame 310, improving the synchronization of the connection actions at each connection point, making the connection process smoother and the established connections more stable, reliable, and secure.

[0066] The bottom of the lifting channel 110 can be equipped with a parking platform 500. The parking platform 500 can be the ground in the narrow sense, or it can be other surfaces, used to support the lowered vehicle loading plate 200. At this time, step S27 specifically includes lowering the lifting frame 310 until the vehicle loading plate 200 lands on the parking platform 500 or the parking platform 500. When there are empty vehicle loading plates 200 in the parking garage (i.e., before all vehicle loading plates 200 in the parking garage are full of vehicles), the parking platform 500 will only have one empty vehicle loading plate 200 before and after all actions are performed. That is, the parking platform 500 reserves an empty vehicle loading plate 200, allowing vehicles outside to enter at any time, and vehicles inside to land and leave at any time. If the parking and retrieval platform 500 does not have a reserved loading plate 200, vehicles outside must wait for an empty loading plate 200 to land before parking, affecting parking speed. If the parking and retrieval platform 500 has too many loading plates 200 (e.g., four), the height difference between the top loading plate 200 and the surface of the parking and retrieval platform 500 is too large, making it difficult or even impossible for vehicles inside and outside to enter or exit, thus affecting parking and retrieval speed.

[0067] When parking a vehicle, the vehicle must first enter an empty loading platform 200 on the parking / retrieval platform 500 before the platform is closed. This action then places the vehicle into the parking space 121, preventing the vehicle from occupying the elevator 110 and hindering the entry or exit of other vehicles. After parking, if no loading platforms 200 are available on the parking / retrieval platform 500, the platform is released, placing any loading platform 200, either empty or loaded with a vehicle, onto the parking / retrieval platform 500. This ensures that only one empty loading platform 200 is reserved on the parking / retrieval platform 500. When retrieving a vehicle, the platform is released, releasing the vehicle from the parking space 121 onto the parking / retrieval platform 500 for easy departure. After retrieving the car, if there are two loading plates 200 on the parking and retrieval platform 500, the plate-collecting action is executed to retract the upper loading plate 200 into the parking space 121 that lacks the loading plate 200, thereby ensuring that the parking and retrieval platform 500 has a unique empty loading plate 200 reserved.

[0068] If a single empty loading plate 200 is reserved on the parking and retrieval platform 500, and parking and retrieval occur sequentially, the loading plate 200 on the parking and retrieval platform 500 that has already received the vehicle to be parked is first retracted, and then the loading plate 200 on the parking and retrieval platform 500 that has received the vehicle to be retrieved is released. This ensures that a single empty loading plate 200 remains on the parking and retrieval platform 500 after the two operations are completed, without requiring any further operations between or after the two operations. Similarly, if a single empty loading plate 200 is reserved on the parking and retrieval platform 500, and if parking and retrieval occur sequentially in the order of retrieval first and storage later, the loading plate 200 with the vehicle to be retrieved in the parking area 120 will be lowered first. After the vehicle to be retrieved leaves and the vehicle to be stored enters, the loading plate 200 with the vehicle to be stored on the parking and retrieval platform 500 will be retracted. No further actions are required before or after the aforementioned two actions to ensure that a single empty loading plate 200 remains on the parking and retrieval platform 500 after the aforementioned actions are completed.

[0069] In the case where a single empty loading plate 200 is reserved on the parking and retrieval platform 500, if no parking occurs before the vehicle is retrieved, there will be one loading plate 200 on the parking and retrieval platform 500 before the vehicle is retrieved. If parking occurs just before the vehicle is retrieved, there may be no loading plates 200 on the parking and retrieval platform 500 before the vehicle is retrieved. If a loading plate 200 is placed on the parking and retrieval platform 500 while one is already on the parking and retrieval platform 500, two overlapping loading plates 200 will appear on the parking and retrieval platform 500. The loading plate 200 originally on the parking and retrieval platform 500 will become the lower loading plate 200, while the loading plate 200 lowered by the placing action will become the upper loading plate 200. In this case, lowering the lower loading plate 200 helps to reduce the height difference between the upper loading plate 200 and the surface of the parking and retrieval platform 500, making it easier for vehicles to enter or leave the loading plate 200. Therefore, if there is a car loading plate 200 on the car storage and retrieval platform 500 before picking up the car, the car loading plate 200 on the car storage and retrieval platform 500 can be lowered when picking up the car, and the car loading plate 200 carrying the vehicle to be picked up in the parking area 120 can be lowered. After picking up the car, the upper car loading plate 200 on the car storage and retrieval platform 500 can be retracted and the lower car loading plate 200 on the car storage and retrieval platform 500 can be floated.

[0070] The lifting frame 310 can be driven by the first driving mechanism 320 and moves in the vertical direction under the drive of the first driving mechanism 320, thereby achieving lifting. The first driving mechanism 320 and the lifting frame 310 can be driven by the first transmission mechanism 330. The second transmission mechanism 430 can adopt a rigid transmission mechanism, such as a ball screw mechanism (composed of a screw, a nut, etc.), or a flexible transmission mechanism, such as a combination of a high-strength steel wire rope, a synthetic fiber rope, or a winder (such as a Figure 1), a combination of chains and sprockets, etc. In these transmission mechanisms, the nuts, ropes, and chains are fixedly connected to the lifting frame 310, and the screws, winders, and sprockets are transmission-connected to the first drive mechanism 320, wherein one end of the rope cooperates with the winder and the other end is fixedly connected to the lifting frame 310, and one end of the chain cooperates with the sprocket and the other end is fixedly connected to the lifting frame 310. In contrast, the winder and sprocket of the flexible transmission mechanism are installed at the top of the lifting channel 110, and the ropes and chains are lifted and lowered together with the lifting frame 310. Any position where they are connected to the lifting frame 310 will not affect the transverse frame 410 entering and exiting the parking space 121, and after executing step S29, it can avoid scratches on vehicles entering and exiting, reduce delays and maintenance needs caused by scratches, improve the operating efficiency of the garage, and allow users to enjoy a faster, smoother, and more comfortable parking experience, thereby enhancing the attractiveness and market competitiveness of the multi-story parking garage. By avoiding wear or accidental damage caused by scratches, the service life of the flexible transmission mechanism is also extended, the frequency of replacement due to wear or accidental damage is reduced, and the maintenance burden and cost of the overall garage structure are reduced. This not only reduces the economic expenditure of the garage operator, but also improves the long-term stability and reliability of the garage equipment.

[0071] like Figures 11-12As shown, the lifting frame 310 can also be guided by a lifting guide rail 341. The lifting guide rail 341 is configured within the lifting channel 110 and extends from the top of the lifting channel 110 to the bottom of the lifting channel 110. The lifting frame 310 is slidably connected to the lifting guide rail 341 and slides along the lifting guide rail 341 under the drive of the first drive mechanism 320, thereby moving in a vertical direction to achieve lifting. The guidance of the lifting guide rail 341 helps to strictly limit the lifting and lowering motion trajectory of the lifting frame 310, thereby facilitating the alignment of the lock button 352 and the lock hole 357 during the process of establishing a connection between the lifting frame 310 and the vehicle loading plate 200, especially when the transmission between the first drive mechanism 320 and the lifting frame 310 is driven by a flexible transmission mechanism. Parking areas 120 are typically located on either side of the elevator 110, while the vehicle entrance and exit are located at the front of the ground floor of the multi-story parking garage. Therefore, lift guide rails 341 can be located at both the front and rear sides of the elevator 110. The lift guide rail 341 located at the rear of the elevator 110 extends from the top of the elevator 110 to the bottom of the elevator 110, while the lift guide rail 341 located at the front of the elevator 110 extends from the top of the elevator 110 to the top of the vehicle entrance and exit. Compared to configuring a lift guide rail 341 at each of the four inner corners of the elevator 110, this can achieve optimal guidance at a lower cost without hindering vehicle entry and exit. At least one pair of pulleys 342 can be located at the front and rear of the lifting frame 310, with space between each pair of pulleys 342 for engagement with the lift guide rails 341. This allows for smoother sliding between the lifting frame 310 and the lift guide rails 341, particularly ensuring smooth docking of the lifting frame 310 with the front lift guide rails 341 when entering and exiting the ground floor.

[0072] like Figure 13 As shown, the transverse frame 410 can be guided by a transverse guide rail 440 and driven by a second drive mechanism 420. Driven by the second drive mechanism 420, it slides along the transverse guide rail 440 to achieve horizontal movement. The transverse guide rail 440 spans the parking area 120 and the elevator channel 110, allowing the transverse frame 410 to move from the parking space 121 into the elevator channel 110 and from the elevator channel 110 back to the parking space 121. The second drive mechanism 420 and the transverse frame 410 can be driven by a second transmission mechanism 430. The second transmission mechanism 430 may include a roller rotatably connected to the transverse frame 410. The roller is in transmission connection with the second drive mechanism 420 and, driven by the second drive mechanism 420, rolls on the transverse guide rail 440, thereby driving the transverse frame 410 to slide along the transverse guide rail 440.

[0073] The first drive mechanism 320 and the second drive mechanism 420 are usually composed of a motor, a controller and a power supply system. The motor serves as a power output device and is respectively connected to the lifting frame 310 and the transverse frame 410. Specifically, a DC brushless motor or a servo motor can be used. The controller is responsible for receiving external instructions (such as a remote control, a touch screen, etc.) and converting them into electrical signals that can be recognized by the motor, controlling the forward and reverse rotation and speed of the motor to achieve precise movement of the lifting frame 310 and the transverse frame 410. The controller may also have safety functions such as overload protection and short-circuit protection to ensure stable operation of the system. The power supply system provides a stable and reliable power supply for the motor and controller, and usually includes mains access, a transformer, a voltage stabilizer and a backup power supply (such as a battery), etc., to ensure that a certain operating time can be maintained in the event of a sudden power outage, so as to safely evacuate the vehicle.

[0074] The connection between the lifting frame 310 and the vehicle loading plate 200 can be established and released via a locking mechanism 350. The locking mechanism 350 can be fixed to the lifting frame 310 or the vehicle loading plate 200. Compared with being fixed to the vehicle loading plate 200, fixing the locking mechanism 350 to the lifting frame 310 is more conducive to protecting the locking mechanism 350 from being crushed or hit by vehicles, thereby extending the service life of the locking mechanism 350, reducing the frequency of replacement due to vehicle crushing or impact damage, and also reducing the maintenance burden and cost of the multi-story parking garage, and improving the stability and reliability of lifting.

[0075] The locking mechanism 350 can have various structural forms, one of which is Figures 14 to 19As shown, the locking mechanism 350 may include a rotating shaft 351, a locking button 352, a transmission assembly 353, and a driving component 354. The driving component 354 is in driving connection with the transmission assembly 353, which is in driving connection with the pin. The lower end of the rotating shaft 351 is fixedly connected to the locking button 352. Driven by the driving component 354, the transmission assembly 353 drives the rotating shaft 351 and the locking button 352 to rotate about the rotating shaft 351. The vehicle loading plate 200 or the lifting frame 310 is provided with a locking hole 357. If the locking mechanism 350 is fixed to the lifting frame 310, the locking hole 357 is provided on the vehicle loading plate 200. If the locking mechanism 350 is fixed to the vehicle loading plate 200, the locking hole 357 is provided on the lifting frame 310. The locking hole 357 allows the locking knob 352 to be inserted or removed when rotated to a first orientation, while locking it in a manner that prevents it from being inserted or removed when rotated to a second orientation. Therefore, after being inserted into the locking hole 357, the locking knob 352 can be rotated to the second orientation, establishing a connection between the lifting frame 310 and the vehicle loading platform 200. After the connection is established, the locking knob 352 can also be rotated to the first orientation and removed from the locking hole 357 to disconnect the lifting frame 310 from the vehicle loading platform 200. This locking mechanism does not rely on electrical power to maintain the connection (the drive component 354 can be powered off after locking). Even if the system loses power or malfunctions, the connection will not be accidentally disconnected, significantly improving the safety of the vehicle loading platform 200 during lifting and parking. During the locking / unlocking process, the locking mechanism 350 only needs to rotate the locking knob 352, facilitating a fast and reliable locking and unlocking cycle, improving the operating efficiency of the garage. The locking / unlocking process does not require additional horizontal movement space, making it ideal for applications such as multi-story garages, where space is extremely limited.

[0076] The surface of the locking button 352 facing away from the rotating shaft 351 can be designed as a conical or spherical surface, which acts as a guide surface. When the locking button 352 approaches the locking hole 357, even if there is a slight misalignment, the conical / spherical surface will contact the edge of the locking hole 357, generating a lateral force component, guiding the locking button 352 automatically into the center of the locking hole 357. This significantly reduces the stringent positioning accuracy requirements between the lifting frame 310 and the vehicle loading plate 200, improves the system's fault tolerance, and reduces misalignment caused by minor deviations. During the insertion process of the locking button 352, the conical / spherical surface contacts the edge of the locking hole 357 gradually (rather than a hard collision with a right-angled edge), effectively buffering impact and extending its service life.

[0077] The transmission assembly 353 can be a meshing worm gear and worm. The worm gear is connected to the rotating shaft 351, and the worm is connected to the output end of the drive component 354. The worm gear transmission has a natural self-locking property. When the drive component 354 stops working, the worm cannot be reversely driven by the worm gear. In other words, the weight of the loading plate 200 or external forces cannot force the lock button 352 to rotate. This helps prevent the loading plate 200 from accidentally falling off and further improves safety. The drive component 354 is typically composed of a motor and other components.

[0078] The locking mechanism 350 may also be configured with a limit assembly 355, which is used to constrain the rotation angle of the rotating shaft 351 and the lock button 352 to prevent the rotating shaft 351 and the lock button 352 from rotating too much or too little, thereby causing a locking or unlocking failure. Specifically, the limit assembly 355 may include a limit block 3551, a first limit switch 3552, and a second limit switch 3553. The limit block 3551 is fixedly connected to the rotating shaft 351. The first limit switch 3552 and the second limit switch 3553 are respectively electrically connected to the driving component 354. The driving component 354 stops driving when the first limit switch 3552 or the second limit switch 3553 detects the limit block 3551. When the first limit switch 3552 detects the limit block 3551, the lock hole 357 allows the lock button 352 to be inserted or withdrawn. When the second limit switch 3553 detects the limit block 3551, the lock hole 357 prohibits the lock button 352 from being inserted or withdrawn. A limit block 3551 is provided along the rotation path of shaft 351, physically limiting the rotation angle of shaft 351 and ensuring that lock knob 352 rotates to the precise locked and unlocked positions. This prevents under- or over-rotation of lock knob 352 due to transmission errors or overshoot of drive component 354, ensuring that the fit between lock knob 352 and lock hole 357 always meets design requirements. Confirming the end point of lock knob 352's rotation using a limit switch is more direct than traditional methods that rely on encoders or timer controls, and helps ensure accurate end point determination.

[0079] Limit block 3551 may include a circular column and a fan-shaped column. The outer wall of the circular column is fixedly connected to the inner wall of the fan-shaped column, and the inner wall of the circular column is fixedly connected to the side of the rotating shaft 351. The fan-shaped column has a first plane and a second plane passing through the rotation axis 351. The first plane faces the first limit switch 3552 when the first limit switch 3552 detects the limit block 3551, and the second plane faces the second limit switch 3553 when the second limit switch 3553 detects the limit block 3551. The difference between the first azimuth angle and the second azimuth angle can be set to 90°, and the angle between the first plane and the second plane can also be set to 90°. Accordingly, the contacts of the first limit switch 3552 and the second limit switch 3553 can be distributed on the same plane as the rotation axis 351.

[0080] The locking mechanism 350 may also be equipped with a mounting assembly 356. The rotating shaft 351, transmission assembly 353 (worm gear), drive assembly 354, and limit assembly 355 (first limit switch 3552 and second limit switch 3553) may all be mounted on the mounting assembly 356. The mounting assembly 356 may be fixedly connected to the lifting frame 310, allowing the locking mechanism 350 to be assembled independently and then mounted on the lifting frame 310. The rotating shaft 351 is rotatably mounted on the mounting assembly 356, allowing it to rotate and drive the knob. Once connected, the rotating shaft 351 can stably withstand the weight of the vehicle loading platform 200 and the vehicle. The rotating shaft 351 may extend through the mounting assembly 356 and the limit block 3551, with the limit block 3551 sandwiched between the upper end of the rotating shaft 351 and the mounting assembly 356. This allows the limit block 3551 to better secure the rotating shaft 351 to the mounting assembly 356. The worm is rotatably mounted on the mounting component 356 , so that the worm is positioned and the worm can be driven by the driving component 354 to rotate and drive the worm wheel to rotate, thereby driving the rotating shaft 351 and the locking button 352 to rotate.

[0081] The lateral moving frame 410 and the vehicle loading plate 200 can be guided and positioned by the positioning posts 451 and the positioning holes 452 so that the vehicle loading plate 200 can be accurately placed on the upper surface of the lateral moving frame 410. The positioning posts 451 can be arranged on the upper side of the lateral moving frame 410 or on the lower side of the vehicle loading plate 200. If the positioning posts 451 are arranged on the upper side of the lateral moving frame 410, the positioning holes 452 that cooperate with the positioning posts 451 should be arranged on the vehicle loading plate 200. In this case, the top surface of the positioning posts 451 can be set to a conical surface or a spherical surface so that it can be inserted into the positioning holes 452 more smoothly, thereby reducing the difficulty of docking the two. If the positioning posts 451 are arranged on the lower side of the vehicle loading plate 200, the positioning holes 452 that cooperate with the positioning posts 451 should be arranged on the lateral moving frame 410. In this case, the bottom surface of the positioning posts 451 can be set to a conical surface or a spherical surface so that it can be inserted into the positioning holes 452 more smoothly, thereby reducing the difficulty of docking the two.

[0082] like Figures 20-21As shown, the parking and retrieval platform 500 can be provided with a recessed pit 510, in which a lifting mechanism 520 is provided. The lifting mechanism 520 is used to support the lowered vehicle loading plates 200 so that the topmost vehicle loading plate 200 is substantially flush with the top surface of the parking and retrieval platform 500, facilitating the entry and exit of vehicles onto or off the vehicle loading plates 200. The lifting mechanism 520 can support at most two vehicle loading plates 200. When supporting two vehicle loading plates 200, the lifting mechanism 520 drives the vehicle loading plates 200 downward. When supporting one vehicle loading plate 200, the lifting mechanism 520 drives the vehicle loading plates 200 upward. In this way, the lifting mechanism 520 only needs to be raised to the highest point or the lowest point, without the need for additional positioning points in between, to ensure that the topmost vehicle loading plate 200 is substantially flush with the top surface of the parking and retrieval platform 500. The lifting mechanism 520 can be configured as a jack, which is conducive to stably, firmly and reliably supporting the vehicle loading plate 200, so that the top vehicle loading plate 200 is kept flush with the top surface of the vehicle storage and retrieval platform 500, especially when the vehicle enters the vehicle loading plate 200.
