[0002] As an efficient parking solution, multi-story parking garages have received widespread attention in recent years. Multi-story parking garages have the advantages of small footprint and large number of parking spaces, which makes them widely used in solving the problem of difficult parking in cities. At present, lifting multi-story parking garages have been used in business districts, office buildings, hospitals and other places. With the advancement of technology, the design and operation of multi-story parking garages will become more intelligent and efficient. This includes but is not limited to automated parking systems, intelligent navigation systems, and a safer and more reliable parking environment. These technological innovations will further promote the development of multi-story parking garages and meet people's growing parking needs.

[0003] At present, in multi-story parking garages, most of the methods for moving and transporting vehicles are directly to use the vehicle bearing plate for moving and transporting, especially for multi-story multi-story parking garages. When parking, the vehicle is driven onto the vehicle bearing plate, and then the vehicle bearing plate is dragged by the lifting and conveying mechanism in the multi-story parking garage, and the vehicle bearing plate and the vehicle are transported to the designated parking space together. Then the lifting and conveying mechanism takes the spare parking plate on the lower side of the parking space and lowers it to the ground for the next vehicle to store and use. When picking up the vehicle, the lifting and conveying mechanism must first move the parking plate on the ground to the bottom of the parking space, and then lower the vehicle in the parking space and the parking plate on which the vehicle is placed to the ground. In this way, through the above parking method, the same mechanical action needs to be repeated many times, which invisibly increases the mechanical action of the multi-story parking process and prolongs the vehicle storage and retrieval time.

[0050] The implementation method of this device:

[0051] The three-dimensional garage includes the above-mentioned three-dimensional garage vehicle transportation device, and also includes a lifting and conveying mechanism and a main controller. The lifting end of the lifting and conveying mechanism is connected to the base 1, and the main controller is electrically connected to the longitudinal telescopic component and the transverse telescopic component 5 respectively. When the vehicle is being transported, the four wheel brackets 6 correspond to the two front wheels and the two rear wheels of the vehicle, and the outer ends of the outer fork bars 63 of at least one wheel bracket 6 corresponding to the front wheels and one rear wheel bracket 6 are provided with ultrasonic emission and echo detectors 7; initially, the lifting and conveying mechanism in the three-dimensional garage is used to move the three-dimensional garage vehicle transportation device as a whole into the bottom of the vehicle. At this time, the wheel bracket 6 is in a retracted state, and the ultrasonic emission and echo detector 7 cannot detect the echo. When the longitudinal telescopic component is used to drive the wheel bracket 6 to extend in the wheelbase direction of the front and rear wheels of the vehicle, when the wheel bracket 6 passes from the side of the wheel, the ultrasonic emission and echo detector 7 will detect an echo. At this time, the wheel bracket 6 is controlled to continue to move. When the outer fork bar 63 of the wheel bracket 6 passes over the wheel, no echo is detected. At this time, the wheel bracket 6 is controlled to move. The longitudinal telescopic assembly of the bracket 6 stops driving, the outer fork 63 of the wheel bracket 6 is on the outside of the wheel, and the inner fork 62 is on the inside of the wheel. At this time, the transverse telescopic assembly 5 between the two bracket transverse sleeves 2 is started, and the corresponding electric hydraulic cylinder 51 is controlled to move the wheel bracket 6 transverse sleeve 2 and the wheel bracket 6 to the lateral direction of the vehicle, so that the fork of the wheel bracket 6 is just stuck in the middle of the wheel. During the movement, the contact sensors arranged in the middle of the outer fork 63 of the wheel bracket 6 and the inner fork 62 of the wheel bracket 6 will contact the wheel. When the main controller in the three-dimensional car park receives the contact signal sent back by the contact sensor, it immediately controls the corresponding electric hydraulic cylinder 51 to stop. At this time, the four wheel brackets 6 are just stuck at the bottom of the four wheels, and then the lifting and conveying mechanism in the three-dimensional car body can be used to realize the transportation of the vehicle and the picking and placing of the vehicle.

[0052] Preferably, in practical applications, four bracket transverse shifting sleeves 2 can also be provided, corresponding to four wheel brackets 6 one by one, and each two bracket transverse shifting sleeves 2 form a group, and a limiting slide bar 4 is inserted in each of the two bracket transverse shifting sleeves 2 in each group, and each limiting slide bar 4 is connected to the corresponding bracket transverse shifting sleeve 2 through a longitudinal telescopic drive unit 3, so that the longitudinal position of each wheel bracket 6 can be adjusted respectively. Furthermore, an electric hydraulic cylinder 51 is respectively provided between each bracket transverse shifting sleeve 2 and the base 1, so that the transverse position of each wheel bracket 6 can be adjusted, so that by cooperating with the lifting and conveying components and the main controller in the stereo garage, it can better adapt to vehicles with inconsistent front and rear wheel tracks and realize the storage and retrieval of vehicles.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
