Description

Technical Field

[0001] This invention relates to the field of intelligent parking garages, and in particular to a vehicle platform storage and retrieval device and a multi-level parking system. Background Technology

[0002] With the development of Chinese society, we have fully entered the automobile era, and the resulting parking difficulties have become a major problem hindering urban development and citizens' travel. To alleviate this problem, multi-level parking garages based on double or multiple parking spaces have emerged.

[0003] The multi-level parking garage includes a vehicle storage and handover area, a vehicle parking area, and a vehicle retrieval and handover area. The vehicle parking area is equipped with vehicle pallet storage racks. When storing or retrieving vehicles, AGVs (Automated Guided Vehicles) move the vehicle pallets between the vehicle pallet storage racks and the vehicle storage and handover area, as well as between the vehicle retrieval and handover area and the vehicle pallet storage racks.

[0004] Because existing multi-level parking garages require AGVs (Automated Guided Vehicles) to move vehicle pallets between the parking area, vehicle storage area, and vehicle retrieval area, this occupies AGV space, reducing the number of AGVs available for vehicle transport and thus lowering the overall parking garage's efficiency. Furthermore, the time spent by AGVs moving the pallets back and forth also contributes to the parking garage's efficiency. Summary of the Invention

[0005] The main objective of this invention is to propose a vehicle loading and unloading device, which aims to solve the technical problem of low vehicle loading and unloading efficiency in existing multi-level parking lots.

[0006] To achieve the above objectives, the present invention proposes a vehicle platform storage and retrieval device for use in a multi-level parking garage, wherein the multi-level parking garage includes a transfer platform, and the vehicle platform storage and retrieval device includes:

[0007] A storage plate device is installed on one side of the handover platform for storing vehicle plates;

[0008] The loading and unloading device is used to remove the vehicle loading plate from the storage plate device and transfer it to the handover platform, or to store the vehicle loading plate on the handover platform into the storage plate device.

[0009] In some embodiments, the storage plate device includes:

[0010] Two upright panels are spaced apart and enclose a storage space for storing vehicle-mounted panels;

[0011] Multiple sets of first support members are installed on the inner side of the two upright plates to support the vehicle platform.

[0012] In some embodiments, two sets of the first support members are provided on the inner side of each of the upright plates, and each set of the first support members includes a plurality of support parts, which are distributed at intervals along the vertical direction.

[0013] In some embodiments, the pick-and-place device includes:

[0014] A lifting mechanism, installed within the storage space, is used to lift and lower the vehicle platform;

[0015] A transfer mechanism is used to transfer a vehicle platform from the lifting mechanism to the handover platform, or to transfer a vehicle platform from the handover platform to the lifting mechanism.

[0016] In some embodiments, the multi-level parking garage further includes a transport device for transporting vehicle platforms and vehicles, and the transfer platform includes two load-bearing members spaced apart in a vertical direction, with a parking space formed between the two load-bearing members for the transport device to move into.

[0017] In some embodiments, the bottom of the upright plate is provided with a first clearance groove, which is in communication with the parking space;

[0018] The transfer mechanism includes a telescopic arm mounted on the lifting mechanism. The telescopic arm can pass through the first clearance slot and move into the parking space to move the vehicle platform on the handover platform from the first clearance slot into the storage space, or to move the vehicle platform in the storage space from the first clearance slot to the handover platform.

[0019] In some embodiments, the carrier is configured with a second clearance groove, which is connected to the first clearance groove and the parking space.

[0020] In some embodiments, the handover platform is provided with two second support members, which are spaced apart and extend toward the inside of the handover platform.

[0021] The present invention further proposes a three-dimensional parking system, including a vehicle carrier, a transfer platform, a transport device, and a vehicle carrier storage and retrieval device as described in the foregoing embodiments. The vehicle carrier storage and retrieval device is located on one side of the transfer platform, and the transport device is used to transport the vehicle carrier and the vehicle.

[0022] In some embodiments, the vehicle platform includes a body and telescopic legs disposed around the periphery of the body, the telescopic legs being movable relative to the body.

[0023] In the technical solution of this invention, the storage plate device is set on one side of the handover platform, which is located in the vehicle storage handover area of ​​the multi-level parking lot. When storing and retrieving the vehicle plate, it can be completed by the pick-and-place device without the need for a handling device, such as an AGV. This reduces the occupation of the handling device and speeds up the storage and retrieval of the vehicle plate, thereby improving the storage and retrieval efficiency of the multi-level parking lot.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention 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 indication will also change accordingly.

[0036] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0037] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0038] This invention proposes a vehicle loading platform storage and retrieval device for use in multi-level parking garages. The multi-level parking garage includes a transfer platform, as shown in the reference. Figure 1 The vehicle platform storage and retrieval equipment includes:

[0039] The storage plate device 1 is set on one side of the handover platform 3 and is used to store the vehicle plate 4;

[0040] The pick-and-place device 2 is used to remove the vehicle plate 4 from the storage plate device 1 and transfer it to the handover platform 3, or to store the vehicle plate 4 on the handover platform 3 into the storage plate device 1.

[0041] In this embodiment, the multi-level parking garage includes a vehicle loading platform storage and retrieval device and a handover platform 3. The handover platform 3 is provided with a vehicle retrieval handover area and a vehicle storage handover area. The vehicle storage handover area is the area that a vehicle needs to enter when it wants to park, and the vehicle retrieval handover area is the area where the vehicle to be retrieved will be moved when the vehicle owner needs to retrieve the vehicle.

[0042] The vehicle platform storage and retrieval equipment includes a storage device 1 and a retrieval device 2. The storage device 1 is located on one side of the transfer platform 3. The retrieval device 2 can move from the storage device 1 to the transfer platform 3, or from the transfer platform 3 to the storage device 1. The storage device 1 is used to store vehicle platforms 4. The storage capacity of the storage device 1 is related to the size of the parking space and the space at the transfer platform 3. When the space around the transfer platform 3 is relatively narrow, the storage capacity of the storage device 1 is less than that of other storage devices 1. In such cases, storage devices 1 can be set up on both sides of the transfer platform 3. The number of vehicle platforms 4 in the storage device 1 matches the number of vehicle parking areas in the multi-level parking garage.

[0043] When a vehicle needs to stop, if there is no vehicle support plate 4 in the vehicle handover area, the vehicle handover area cannot be used for parking. In this case, the retrieval device 2 will remove the vehicle support plate 4 from the storage plate device 1 and transfer it to the vehicle handover area. The vehicle can then drive into the vehicle handover area and stop on the vehicle support plate 4. When multiple vehicles need to be retrieved, as the vehicles in the retrieval handover area leave the vehicle support plate 4, the retrieval device 2 will transport the vehicle support plate 4 from the handover platform 3 back to the storage plate device 1 to avoid affecting subsequent vehicles waiting to be retrieved. When only one vehicle needs to be retrieved, the retrieval device 2 will not transport the vehicle support plate 4 from the handover platform 3 back to the storage plate device 1.

[0044] The picking and placing device 2 can be a mechanical gripper, a telescopic rod, a lift, or a conveyor belt. However, the picking and placing device 2 can transport the vehicle platform 4 from the storage device 1 to the transfer platform 3, or from the transfer platform 3 to the storage device 1, without affecting the storage of the vehicle platform 4. The storage device 1 is located on one side of the transfer platform, and the picking and placing device 2 can move from the storage device 1 to the transfer platform 3, or from the transfer platform 3 to the storage device 1. This eliminates the need for a handling device to transport the vehicle platform 4 from a distant storage rack, thus speeding up the transport time of the vehicle platform and reducing vehicle parking time.

[0045] In some embodiments, see Figure 1 and Figure 2 The storage plate device 1 includes:

[0046] Two upright panels 11 are spaced apart and enclose each other to form a storage space 13 for storing the vehicle platform 4;

[0047] Multiple sets of first support members 12 are set on the inner side of the two upright plates 11 to support the vehicle platform 4.

[0048] In this embodiment, the storage plate device 1 is used to store the vehicle plate 4. It can be a box-shaped box with an upward opening, in which the vehicle plate 4 is stored by stacking. Alternatively, it can be two upright plates 11, with a storage space 13 formed between them. A first support member 12 is then provided on the two upright plates 11 to fix the vehicle plate 4 in the storage space 13. However, for ease of maintenance and movement of the retrieval device 2, the structure of the two upright plates 11 is more convenient for maintenance. The width of the vehicle plate 4 is adapted to the width of the two upright plates 11. The first support member 12 provided on the upright plate 11 can protrude relative to the upright plate 11, allowing the vehicle plate 4 to overlap the first support member 12, or it can be recessed relative to the upright plate 11, allowing the vehicle plate 4 to be fixed in the first support member 12.

[0049] In some embodiments, see Figure 1 and Figure 2 Each upright plate 11 has two sets of first support members 12 on its inner side. Each set of first support members 12 includes multiple support parts 121, which are distributed at intervals along the vertical direction.

[0050] In this embodiment, there are multiple first support members 12. Two sets of first support members 12 are provided on the inner side of each upright plate 11, thereby forming four sets of first support members 12 in pairs, which can more stably fix the vehicle plate 4 and prevent the vehicle plate 4 from shaking or falling into the storage space 13 due to uneven force.

[0051] Each first support member 12 includes multiple support parts 121, which are distributed at intervals along the vertical direction. The support parts 121 are arranged at intervals in the first support member 12, and each support part 121 in each group of first support members 12 corresponds to each other horizontally. When the vehicle platform 4 is fixed in the storage space 13, the vehicle platform 4 will simultaneously abut against the support parts 121 on the same horizontal plane. In this way, more vehicle platforms 4 can be stored in the storage space 13 in a stacked manner.

[0052] In some embodiments, see Figures 1-4 The pick-and-place device 2 includes:

[0053] Lifting mechanism 21 is installed in storage space 13 and is used to lift vehicle platform 4;

[0054] The transfer mechanism 22 is used to transfer the vehicle platform 4 on the lifting mechanism 21 to the handover platform 3, or to transfer the vehicle platform 4 on the handover platform 3 to the lifting mechanism 21.

[0055] In this embodiment, the pick-and-place device 2 has various configurations. This solution adopts the method of using the lifting mechanism 21 and the transfer mechanism 22 in combination to transport the vehicle platform 4.

[0056] The lifting mechanism 21 is installed in the storage device 1. Its main function is to drive the vehicle platform 4 to move up and down in the storage device 1 through a lifting motion. Since the vehicle platform 4 moves up and down, it is stored in the storage device 1 in a stacked manner. When it is necessary to store the vehicle platform 4, the lifting mechanism 21 will move it to a specific position, and then move it to the transfer platform 3 through the transfer mechanism to transport the vehicle platform 4 back to the storage device 1. When it is necessary to remove the vehicle platform 4, the lifting mechanism 21 will move the vehicle platform 4 to a specific position, and then transport it to the transfer platform 3 through the transfer mechanism 22.

[0057] In some embodiments, see Figure 2 The multi-level parking garage also includes a transport device for transporting the vehicle platform 4 and the vehicle. The transfer platform 3 includes two load-bearing members spaced apart in the vertical direction, and a parking space 33 is formed between the two load-bearing members for the transport device to move in.

[0058] In this embodiment, the transport trolley includes an AGV trolley for transporting vehicle-carrying pallets 4. The AGV trolley moves the vehicle-carrying pallets 4 between the transfer platform 3 and the vehicle parking area in the multi-level parking garage.

[0059] The handover platform 3 also includes an opening for the passage and transport device, which is connected to the parking space 33. The opening can face the storage device 1 or other directions. The vehicle platform 4 is fixed on the carrier and located above the parking space. However, the opening direction cannot be opposite to the vehicle parking area because the transport device needs to enter the handover platform 3 to transport the vehicle platform 4 carrying the vehicle back to the vehicle parking area, or to transport the vehicle platform 4 carrying the vehicle from the vehicle parking area to the handover platform 3. The transfer mechanism 22 and the transport device both move into the parking space 33 to lift their vehicle platform 4 and then transport it to the storage device 1 or back to the vehicle parking area.

[0060] In some embodiments, see Figure 6 and Figure 7 The bottom of the upright plate 11 has a first clearance groove 111, which is connected to the parking space 33.

[0061] The transfer mechanism 22 includes a telescopic arm 221 mounted on the lifting mechanism 21. The telescopic arm 221 can pass through the first clearance groove 111 and move into the parking space 33 to move the vehicle platform 4 on the transfer platform 3 from the first clearance groove 111 into the storage space 13, or to move the vehicle platform 4 in the storage space 13 from the first clearance groove 111 onto the transfer platform 3.

[0062] In this embodiment, a first clearance groove 111 is constructed at the bottom of the upright plate 11. The first clearance groove 111 is connected to the parking space 33. The transfer mechanism 22 needs to pass through the first clearance groove 111 to enter the parking space 33. The width of the first clearance groove 111 is adapted to the width of the vehicle platform 4. The transfer mechanism 22 can carry the vehicle platform 4 through the first clearance groove 111. The position of the first clearance groove 111 is the specific position where the lifting mechanism 21 needs to stop. Only when the transfer mechanism 22 enters the parking space 33 can it lift the vehicle platform 4. The transfer mechanism 22 carries the vehicle platform 4 into the parking space 33. The transfer mechanism 22 includes a telescopic arm 221, which can move between the storage device 1 and the transfer platform 3 by telescopic movement. In order to cooperate more closely with the lifting mechanism 21, the transfer mechanism 22 is mounted on the lifting mechanism 21. When the vehicle platform 4 is taken out, the lifting mechanism 21 rises and falls in the storage device 1, and the transfer mechanism 22 abuts against the vehicle platform 4. When the lifting mechanism 21 moves to a specific position, the telescopic arm 221 of the transfer mechanism 22 drives the vehicle platform 4 to start telescopic movement together, so that the vehicle platform 4 can be transported to the transfer platform 3.

[0063] In some embodiments, see Figures 4-7 The carrier has a second clearance groove 311, which is connected to the first clearance groove 111 and the parking space 33 respectively.

[0064] In this embodiment, the opening direction of the transfer platform 3 for the passage and transport device is perpendicular to the upright plate 11, and the bearing member 31 is in contact with the upright plate 11. Therefore, a second clearance groove 311 needs to be opened so that the transfer mechanism 22 can pass through the second clearance groove 311 and enter the parking space 33. To further explain: when the transfer mechanism 22 drives the vehicle plate 4 into the parking space 33, the lifting mechanism 21 needs to drive the transfer mechanism 22 to descend so that the vehicle plate 4 can be placed on the transfer platform. However, if the second clearance groove 311 is not opened, when the lifting mechanism 21 descends, the transfer mechanism 22 will collide with the bearing member 31 and cannot descend, thus making it impossible to place the vehicle plate 4. Therefore, the second clearance groove 311 needs to be opened.

[0065] In some embodiments, see Figure 2 and Figure 4Two second support members 32 are provided on the handover platform 3. The two second support members 32 are spaced apart and extend toward the inside of the handover platform 3.

[0066] In this embodiment, the handover platform 3 is provided with two second support members 32, which are spaced apart and used to fix the vehicle platform 4. When the vehicle platform 4 is placed directly on the support member 31, the support member 31 will be worn when the vehicle drives into or out of the vehicle platform 4. Therefore, the second support members 32 are provided to fix the vehicle platform 4. A part of the second support member 32 is in the parking space 33, that is, the second support member 32 will extend towards the inside of the handover platform 3. The extension distance does not affect the handling device from lifting the vehicle platform 4 and carrying the vehicle platform 4 away from the parking space 33.

[0067] The present invention further proposes a multi-level parking system, which includes a multi-level parking system. The specific structure of the vehicle platform storage and retrieval device is as described in the above embodiments. Since the vehicle platform storage and retrieval device adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0068] In some embodiments, see Figure 1 and Figure 2 The vehicle pallet storage and retrieval equipment is located on one side of the handover platform 3, and the handling device is used to handle the vehicle pallet 4 and the vehicle.

[0069] In this embodiment, the vehicle platform storage and retrieval device is located on one side of the handover platform 3, and the handling device is used to handle the vehicle platform 4 and the vehicle.

[0070] In some embodiments, see Figure 7 The vehicle platform 4 includes a main body 41 and telescopic support legs 42 disposed around the main body 41. The telescopic support legs 42 can move relative to the main body 41.

[0071] In this embodiment, the vehicle platform 4 includes telescopic legs 42 within the main body 41. The telescopic legs 42 can move relative to the main body 41, extending or retracting. The telescopic legs 42 are used in conjunction with the first support member 12. When the telescopic legs 42 of the vehicle platform 4 extend, the vehicle platform 4 is fixed in the storage device 1, and the extended telescopic legs 42 cooperate with the first support member 12 to fix it on the first support member 12. This process is the state of the telescopic legs 42 of the vehicle platform 4 when storing the vehicle platform 4. When the telescopic legs 42 retract into the main body 41, the vehicle platform 4 is detached from the first support member 12. This process is the state of the telescopic legs 42 of the vehicle platform 4 when removing the vehicle platform 4.

[0072] This invention further proposes a method for storing and retrieving a vehicle-mounted plate; please refer to [link to relevant documentation]. Figure 8 This includes the following steps:

[0073] In step S10, when storing the vehicle platform 4, the lifting mechanism 21 is controlled to descend to the first preset position, and then the transfer mechanism 22 is controlled to transfer the vehicle platform 4 from the outside of the storage space 13 into the storage space 13. Then the lifting mechanism 21 is controlled to drive the vehicle platform 4 to rise, so as to place the vehicle platform 4 in the second preset position.

[0074] In step S20, when the vehicle platform 4 is taken out, the lifting mechanism 21 is controlled to rise to the third preset position. After the vehicle platform 4 is taken out, the lifting mechanism 21 is controlled to fall to the first preset position. Then, the transfer mechanism 22 is controlled to transfer the vehicle platform 4 from the storage space 13 to the outside of the storage space 13.

[0075] In one specific embodiment, please refer to Figure 9 The method for storing vehicle-mounted pallets proposed in this invention includes:

[0076] Step 101: After receiving the retrieval information, the main control system determines the first height to be stored.

[0077] The main control system's management records contain information on the storage and retrieval of each vehicle platform 4, used to determine the current quantity in device 1. The first height refers to the lifting height required by the lifting mechanism 21 in device 1. The main control system stores a first mapping table between the number of vehicle platforms 4 already stored in the storage space and the lifting height. The calculation method can be as follows: the main control system records the position of each vehicle platform 4, counted as position 1, position 2, position 3... position X; empty vehicle platforms are recorded as quantity X (X is the total number of vehicle platforms 4 in the warehouse), and quantity Y (Y is the current number of vehicle platforms 4 in the warehouse); the operation of the lifting mechanism 21 is recorded as state A, the operation of the transfer mechanism 22 is recorded as state B, the number of times vehicle platforms 4 are retrieved is recorded as M, and the number of times vehicle platforms 4 are stored is recorded as N; when retrieving a vehicle platform 4, when the lifting mechanism 21 rises to the set position, it will retrieve the vehicle platform 4, then the lifting mechanism 21 will descend, and the transfer mechanism 22 will move to transport the vehicle platform 4 to the transfer platform 3, thus completing the retrieval process. When the command to store vehicle platform 4 ends, the main control system records this process as AB and the count status as -1. When storing vehicle platform 4, the transfer mechanism 22 first moves to below vehicle platform 4 and then transports vehicle platform 4 to the storage device 11. Then, the lifting mechanism 21 is activated. When the lifting mechanism 21 rises and transports vehicle platform 4 to the set position, the command to store vehicle platform 4 ends, and the microcontroller records this process as BA and the count status as +1. When the set position needs to be known, the loading / unloading... The set position is obtained by adding the counted states of vehicle platform 4 and storage vehicle platform 4. This process is recorded as Z, and the formula is established as: Z = N*BA + M*AB. The set position of vehicle platform 4 is recorded as K, and the set position of storage vehicle platform 4 is recorded as T. By derivation, we can obtain K = |Z| + 1, T = |Z|. The relationship between X, Y, and Z is: Y = X + Z. |Z| is the absolute value of Z. In addition to this calculation method, other calculation methods can also be used to obtain the first target position.

[0078] Step 102: Send a first operating signal to the lifting mechanism 21. The first operating signal contains the first target position and the first height. After the main control system determines the first target position, it sends a first operating signal to the lifting mechanism 21. The first operating signal contains the first target position and the first height. The first target position is the spatial position and coordinate information of the vehicle platform 4. The first height is the lifting height of the lifting mechanism 21.

[0079] After receiving the first operating information, the lifting mechanism 21 lifts to the first height. After receiving the first operating signal from the main control system, the first drive component controls the carrier component 31 to lift the transfer mechanism 22 to the first height.

[0080] Step 103: The main control system sends the first drive information to the vehicle platform 4, controls each telescopic support leg 42 of the vehicle platform 4 to switch to the retracted state, the vehicle platform 4 is detached from the frame, the transfer mechanism 22 on the lifting mechanism 21 supports the vehicle platform 4, and the lifting mechanism 21 lifts to the first height and maintains the first height.

[0081] After receiving the first drive information, the vehicle platform 4 on the transfer mechanism 22 controls each telescopic outrigger 42 to switch to the retracted state. When the command is completed, each telescopic outrigger 42 retracts from the frame into the vehicle platform 4, and the vehicle platform 4 detaches from the frame. Alternatively, the first target position information can be sent to the frame in the vehicle platform 4, and the frame at the first height can drive each frame of the vehicle platform 4 to switch to the retracted state after receiving the first target position information.

[0082] The lifting mechanism 21 is reset. After the transfer mechanism 22 picks up the vehicle plate 4, the lifting mechanism 21 is reset. At this time, the transfer mechanism 22 and the vehicle plate 4 correspond to the first clearance groove 111.

[0083] Step 104: The main control system sends a second operating signal to the transfer mechanism 22. The second operating signal includes a first length, which refers to the distance between the transfer mechanism 22 and the handover platform 3. The first length is further interpreted as a fixed length, which is the distance measured when assembling the vehicle platform storage and retrieval equipment, and therefore does not need to be calculated by the main control system.

[0084] Upon receiving the second operating signal, the transfer mechanism 22 drives the vehicle carrier 4 through the first clearance groove 111 and the second clearance groove 311, moving it to the first length. After receiving the signal, the transfer mechanism 22 carries the vehicle carrier 4, first passing through the first clearance groove 111 to leave device 1, and then passing through the second clearance groove 311 until it reaches the first length, at which point the transfer mechanism 22 stops extending and retracting.

[0085] Step 105: The main control system sends a third operating signal to the lifting mechanism 21. The third operating signal includes a preset height, which refers to the descent height of the lifting mechanism 21. The preset height can be further interpreted as a fixed height. When assembling the vehicle platform storage and retrieval equipment, the relationship between the lifting mechanism 21 and the first clearance groove 111, the second clearance groove 311, and the platform is measured. The preset height can be further interpreted as the height at which the lifting mechanism 21 drives the transfer mechanism 22 to descend together, so that the transfer mechanism 22 will just detach from the vehicle platform 4, thereby causing the vehicle platform 4 to be completely fixed on the transfer platform 3. This height is called the preset height.

[0086] When the lifting mechanism 21 receives the third operating signal, it drives the transfer mechanism 22 to descend to the preset height. During the descent, the vehicle platform 4 is connected to the transfer platform 3 through the various second support members 32. The vehicle platform 4 is separated from the transfer mechanism 22, and the lifting mechanism 21 moves to the preset height. Since the transfer mechanism 22 is fixed on the lifting mechanism 21, the lifting and lowering of the lifting mechanism 21 will drive the transfer mechanism 22 to rise and fall together. The transfer mechanism 22 resets, and the lifting mechanism 21 resets. When the lifting mechanism 21 reaches the preset height, after the third operating signal is completed, the transfer mechanism 22 resets. After the reset command of the transfer mechanism 22 is completed, the lifting mechanism 21 begins to execute the reset command.

[0087] In another specific embodiment, please refer to Figure 10 The method for removing the vehicle platform proposed in this invention includes:

[0088] Step 201: After receiving the storage information, the main control system determines the second height to be stored;

[0089] The main control system's management records contain information on the storage and retrieval of each vehicle platform 4, used to determine the current quantity in device 1. The first height refers to the lifting height required by the lifting mechanism 21 in device 1. The main control system stores a first mapping table between the number of vehicle platforms 4 already stored in the storage space and the lifting height. The calculation method can be as follows: the main control system records the position of each vehicle platform 4, counted as position 1, position 2, position 3... position X; empty vehicle platforms are recorded as quantity X (X is the total number of vehicle platforms 4 in the warehouse), and quantity Y (Y is the current number of vehicle platforms 4 in the warehouse); the operation of the lifting mechanism 21 is recorded as state A, the operation of the transfer mechanism 22 is recorded as state B, the number of times vehicle platforms 4 are retrieved is recorded as M, and the number of times vehicle platforms 4 are stored is recorded as N; when retrieving a vehicle platform 4, when the lifting mechanism 21 rises to the set position, it will retrieve the vehicle platform 4, then the lifting mechanism 21 will descend, and the transfer mechanism 22 will move to transport the vehicle platform 4 to the transfer platform 3, thus completing the retrieval process. When the command to store vehicle platform 4 ends, the main control system records this process as AB and the count status as -1. When storing vehicle platform 4, the transfer mechanism 22 first moves to below vehicle platform 4 and then transports vehicle platform 4 to the storage device 11. Then, the lifting mechanism 21 is activated. When the lifting mechanism 21 rises and transports vehicle platform 4 to the set position, the command to store vehicle platform 4 ends, and the microcontroller records this process as BA and the count status as +1. When the set position needs to be known, the loading / unloading... The set position is obtained by adding the counted states of vehicle platform 4 and storage vehicle platform 4. This process is recorded as Z, and the formula is established as: Z = N*BA + M*AB. The set position of vehicle platform 4 is recorded as K, and the set position of storage vehicle platform 4 is recorded as T. By derivation, we can obtain K = |Z| + 1, T = |Z|. The relationship between X, Y, and Z is: Y = X + Z. |Z| is the absolute value of Z. In addition to this calculation method, other calculation methods can also be used to obtain the first target position.

[0090] Step 202: The main control system issues a fourth operating signal to the lifting mechanism 21. The fourth operating signal includes a preset height, which is further interpreted as a fixed height. When assembling the vehicle platform storage and retrieval equipment, the relationship between the lifting mechanism 21 and the first clearance groove 111, the second clearance groove 311 and the platform is measured. The preset height is further interpreted as the height at which the lifting mechanism 21 drives the transfer mechanism 22 to descend together, so that the transfer mechanism 22 will just detach from the vehicle platform 4, thereby causing the vehicle platform 4 to be completely fixed on the transfer platform 3. This height is called the preset height.

[0091] After receiving the fourth operating signal, the lifting mechanism 21 descends to the preset height. During the descent of the telescopic lifting mechanism 21, it will drive the already reset transfer mechanism 22 to descend together to reach the preset height.

[0092] In step S203, the main control system sends a fifth operating signal to the transfer mechanism 22. The fifth operating signal includes a first length, which is further interpreted as a fixed length, the distance measured when assembling the vehicle platform storage and retrieval equipment, and therefore does not require calculation by the main control system.

[0093] When the transfer mechanism 22 receives the fifth operating signal, it moves to the first length. Then, the lifting mechanism 21 resets. Through the reset of the lifting mechanism 21, the transfer mechanism 22 lifts the vehicle platform 4 and separates it from the transfer platform 3. The transfer mechanism 22 runs unloaded, first passing through the first avoidance groove 111, then through the second avoidance groove 311, and arrives at the vehicle parking area. When the transfer mechanism 22 completes the fifth operating signal, the lifting mechanism 21 resets. The reset of the lifting mechanism 21 will drive the transfer mechanism 22 to lift the vehicle platform 4, so that the vehicle platform 4 is completely separated from the transfer platform 3.

[0094] In step S204, the main control system sends a sixth operating signal to the lifting mechanism 21. The sixth operating signal includes the second height and the second position information. The second position information is the spatial position and coordinate information of the second height recorded based on the second height. After receiving the sixth operating signal, the lifting mechanism 21 rises to the second height.

[0095] After receiving the sixth operating signal, the lifting mechanism 21 will drive the transfer mechanism 22 and the vehicle platform 4 to rise together until they reach the second height and remain stationary.

[0096] In step S205, the main control system sends out a second drive signal.

[0097] When the lifting mechanism 21 reaches the second height, the sixth operating signal ends, and the main control system sends a second drive signal. The second drive signal is a command issued and is relative to the first drive information. The first drive signal controls the telescopic outrigger 42 to retract into the body 41, and the second drive signal controls the telescopic outrigger 42 to extend out of the body 41.

[0098] Upon receiving the second drive signal, the telescopic support legs 42 of the vehicle platform 4 are extended. The telescopic support legs 42, which are retracted inside the vehicle platform 4, are driven to extend from inside the vehicle platform 4, so that they can be attached to the frame to fix the vehicle platform 4. The lifting mechanism 21 is reset, and the relocation mechanism 22 is also reset.
