[0002] Multi-level parking garages have high space utilization and are the mainstream trend for the future development of parking lots. Multi-level parking garages that use AGVs to park and transport small cars can effectively solve the problem of parking difficulties and provide a more efficient, faster, and more convenient experience in storing and retrieving vehicles.

[0003] Traditional AGV parking and transportation vehicles consist of a vehicle body, a drive mechanism, and a navigation and positioning system. The drive mechanism moves the vehicle body, and the navigation and positioning system guides it to the appropriate location and transports the vehicle to the target parking space, which can improve the user's parking experience. The drive mechanism is generally composed of a servo motor and movable wheels. The control system controls the servo motor to drive the movable wheels, thereby moving the vehicle body and realizing automated movement.

[0004] However, when tires are damaged, personnel need to manually enter the parking area to remove and replace them, which is very troublesome and time-consuming, and affects the overall parking efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an AGV parking and handling device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An AGV parking and transport device includes a vehicle body and main wheels disposed at its four ends. A servo motor is installed in the vehicle body and connected to the main wheels. Support plates are slidably installed above each set of servo motors at the four ends of the vehicle body. An intermediate plate is installed under the support plate. The intermediate plate is rotatably connected to the support plate through a rotating rod. A spare wheel is installed on one side of the intermediate plate. The main wheels and the spare wheels are each slidably connected to the intermediate plate through connecting rods. A vertical rod is installed on the connecting rod. A support rod is connected to the lower end of the vertical rod through a telescopic spring. A connecting block is installed under the support rod and slidably connected to the outer wall of the connecting rod. A telescopic air pipe is installed between the vertical rod and the support rod. One end of the telescopic air pipe is provided with a delivery port connected to an air pump. A rotating assembly is installed on the support plate. One end of the rotating assembly is connected to the rotating rod. The rotating assembly can drive the rotating rod to rotate around its own central axis by a certain angle when driven.

[0007] Preferably, a drive wheel is provided on the outer wall of the vehicle body. The drive wheel is connected to a motor via a reducer. Driven wheels are provided opposite to each other at the left and right ends of the drive wheel. The driven wheels are rotatably connected to the vehicle body via a rotating rod. A U-shaped plate is slidably provided on the outer wall of the vehicle body. The inner wall of the U-shaped plate meshes with the drive wheel via a rack. A rack is provided on each of the opposite sides of the outer wall of the U-shaped plate, respectively meshing with two sets of driven wheels. A wedge-shaped groove is provided on the lower side of the support plate. A linkage plate is provided on the driven wheel. One end of the linkage plate is provided with a wedge-shaped plate that is slidably connected to the wedge-shaped groove, and the other end is provided with a rack that meshes with the driven wheel.

[0008] Preferably, the output end of the servo motor is fitted with a positioning plate, the positioning plate has a positioning groove, and the drive wheel and the spare wheel are each provided with a positioning rod that is inserted into the positioning groove.

[0009] Preferably, the rotating assembly includes a drive motor mounted on the support plate and a drive wheel sleeved on its output shaft, and a drive wheel meshing with the drive wheel is sleeved on the rotating rod.

[0010] Preferably, the system also includes a lifting assembly, which includes an extension plate fitted at one end onto the rotating rod and a fixed wheel disposed at the other end of the extension plate.

[0011] Preferably, the expansion plate has a groove along its length, a pusher is provided on the outer wall of the vehicle body, a connecting plate is provided at the top of the piston rod of the pusher, and one side of the connecting plate is slidably connected to the groove through a sliding rod.

[0012] The beneficial effects of this utility model are as follows: By setting a support plate on the vehicle body, and rotating a middle plate under the support plate, with main wheels and spare wheels on opposite sides of the middle plate, the position between the main wheels and spare wheels is changed by a rotating component to connect with the servo motor, eliminating the need for manual operation. Compared with the prior art, this utility model reduces the amount of manual labor required for wheel replacement. Simultaneously, the motor-driven drive wheel meshes with a rack on the U-shaped plate, and two sets of racks on the outer wall of the U-shaped plate mesh with the left and right driven wheels. An extension plate is fitted onto a rotating rod connecting the driven wheels to the vehicle body, with fixed wheels on the extension plate in contact with the ground. Therefore, when the main wheels and spare wheels are swapped, the extension plate can be driven to raise the height of the vehicle body through the support of the fixed wheels, allowing the main wheels and spare wheels to rotate and swap positions at a certain distance from the ground, reducing excessive friction with the ground during the swapping process.

[0023] like Figures 1 to 5 As shown, an AGV parking and handling device includes a vehicle body 1 and main wheels 2 disposed at its four ends. In this embodiment, four sets of main wheels 2 are disposed at the four ends of the vehicle body 1. Servo motors 173 are installed at the four ends of the vehicle body 1 and connected to each set of main wheels 2. L-shaped support plates 4 are horizontally slidably disposed above each set of servo motors 173 at the four ends of the vehicle body 1. A middle plate 5 is vertically disposed below the support plate 4. The upper side of the middle plate 5 is rotatably connected to the upper end of the support plate 4 through a rotating rod 6. Spare wheels 7 are also disposed below the support plate 4. The number of spare wheels 7 is the same as that of the main wheels 2 and they are opposite each other. The main wheels 2 and the opposite spare wheels 7 are slidably connected to the middle plate 5 through connecting rods 8. A positioning plate 27 is sleeved on the top of the output shaft of the servo motor 173. A positioning groove 28 is opened on the side of the positioning plate 27 away from the servo motor 173. Positioning rods 29 that are inserted into the positioning groove 28 are provided on the side of the main wheels 2 and the spare wheels 7 away from each other.

[0024] In this embodiment, a movable groove (not shown in the attached figure) is provided along the length of the intermediate plate 5. One end of the connecting rod 8 is movably connected to the movable groove. The connecting rod 8 can slide along the movable groove or rotate around its own central axis. The purpose is that when the servo motor 173 drives the main wheel 2 or the spare wheel 7, the connecting rod 8 connected to the main wheel 2 or the spare wheel 7 can rotate its own central axis at one end of the movable groove.

[0025] The middle plate 5 is T-shaped, with uprights 9 vertically arranged on the left and right sides of its upper end. The lower end of the uprights 9 is connected to a support rod 12 via a telescopic spring 11. The lower end of the support rod 12 is connected to the outer wall of the connecting rod 8 via a connecting block 13. The connecting block 13 is slidably connected to the outer wall of the connecting rod 8. A telescopic air pipe 10 is also provided between the uprights 9 and the support rod 12. The upper end of the telescopic air pipe 10 is provided with a delivery port 14 that communicates with an air pump (not shown in the attached figure). The purpose is to enable the telescopic air pipe 10 to extend through the operation of the air pump. A drive motor 30 is provided on the upper side of the support plate 4. The output shaft of the drive motor 30 is fitted with a drive wheel 31. A drive wheel 32 that meshes with the drive wheel 31 is fitted on the rotating rod 6.

[0026] A drive wheel 15 is rotatably mounted on the middle of both the left and right sides of the vehicle body 1. The drive wheel 15 is connected to the motor 17 via a reducer 16. In this embodiment, the reducer 16 is reversible. Driven wheels 18 are mounted opposite each other on the left and right ends of the drive wheel 15. The driven wheels 18 are rotatably connected to the outer wall of the vehicle body 1 via a rotating rod 19. A U-shaped plate 20 is mounted between the drive wheel 15 and the driven wheel 18. The U-shaped plate 20 is slidably connected to the outer wall of the vehicle body 1. A rack 21 that meshes with the drive wheel 15 is mounted on one side of the inner wall of the U-shaped plate 20 along its length. A rack 21 is mounted on the left and right sides of the outer wall of the U-shaped plate 20 along its length. Each of the two sets of racks 22 is provided along its length, and the two sets of racks 22 mesh with the two sets of driven wheels 18 respectively. A wedge groove 23 is provided on the lower side of the support plate 4. A linkage plate 25 is provided on the driven wheel 18. A wedge plate 24 that slides in connection with the wedge groove 23 is provided at the end of the linkage plate 25 away from the driven wheel 18. A rack 3 26 that meshes with the driven wheel 18 is provided at the other end of the linkage plate 25. It should be noted that the U-shaped plate 20 and the linkage plate 25 are not on the same plane. They are arranged one in front of the other. The purpose of this is to avoid interference between the U-shaped plate 20 and the linkage plate 25 during the upward movement of the linkage plate 20.

[0027] An extension plate 33 is fitted onto the rotating rod 19. A fixed wheel 34 is provided at the end of the extension plate 33 away from the rotating rod 19. A groove 35 is provided on the outer wall of the extension plate 33 along its length. A pusher 36 is provided on the outer wall of the vehicle body 1. In this embodiment, the pusher 36 is a hydraulic cylinder. A connecting plate 37 is connected to the top of its piston rod. One side of the connecting plate 37 is slidably connected to the groove 35 through a sliding rod 38. The purpose is to improve the support force of the extension plate 33.

[0028] When the vehicle body 1 is running normally, the main wheel 2 is in contact with the ground, the telescopic air pipe 10 at the spare wheel 7 is in a non-air-intake state, the telescopic spring 11 at that location is in an initial unstretched state, the spare wheel 7 is not at the same height as the main wheel 2, the spare wheel 7 is not in contact with the ground, the positioning rod 29 at the main wheel 2 is engaged with the positioning groove 28 on the positioning plate 27, the pusher 36 is in a retracted state, and the fixed wheel 34 is not in contact with the ground.

[0029] When one or more sets of main wheels 2 are damaged, personnel can control the vehicle body 1 to stop first through the control system, and then start the motor 17 to reverse. The motor 17 meshes with rack 21, driving the U-shaped plate 20 to move upward. During the upward movement, rack 22 meshes with driven wheel 18. Driven wheel 18 drives extension plate 33 to rotate around the central axis of rotating rod 19 by rotating rod 19. Pushing member 36 extends synchronously, cooperating with fixed wheel 34 to move downward. Fixed wheel 34 begins to rotate and move downward to contact the ground, lifting vehicle body 1 and causing drive wheel 15 to leave the ground. It should be noted that when the main wheel 2 leaves the ground, the sliding engagement of wedge plate 24 and wedge groove 23 just reaches the point where the support plate 4 can be pushed horizontally away from vehicle body 1. During the process of fixed wheel 34 lifting vehicle body 1, it continuously pushes support plate 4 away from vehicle body 1 to a certain distance. Then, the drive motor 30 starts to rotate forward, driving the rotating rod 6 through the meshing of the drive wheel 31 and the driving wheel 32. The intermediate plate 5 is also rotated synchronously, causing the main wheel 2 and the spare wheel 7 to switch positions. At the same time, the telescopic air pipe 10 at the drive wheel 15 stops taking in air, the telescopic spring 11 retracts, the drive wheel 15 is indirectly pulled upward, and the telescopic air pipe 10 at the spare wheel 7 starts to take in air, pushing the support rod 12 downward. The connecting block 13 at the lower end of the support rod 12 simultaneously pushes the connecting rod 8 at the spare wheel 7 downward. The spare wheel 7 moves down to the appropriate position, and then the motor 17 starts to rotate forward. The fixed wheel 34 moves away from the ground again. At this time, the entire vehicle body 1 moves down, and the spare wheel 7, which is opposite to the damaged main wheel 2, is supported on the ground. The damaged main wheel 2 is raised and does not contact the ground. Personnel can control the vehicle body 1 to move to the repair area or continue the transportation work.

[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
