Abstract
Description
Technical Field
[0001] This invention relates to the field of parking lot traffic guidance equipment technology, and in particular to an automated parking guidance vehicle. Background Technology
[0002] A parking lot is an area that provides temporary or long-term parking services for vehicles. It usually consists of parking spaces, passageways, entrances and exits, and necessary management facilities. Before a vehicle enters a parking lot, it cannot determine where there are available parking spaces. After entering the parking lot, the vehicle still needs to search for one on its own. During holidays or when parking spaces are scarce, blindly searching may result in vehicle scratches, posing certain safety hazards.
[0003] To address the aforementioned issues, a search revealed Chinese patent application number CN202411888035.3, which discloses a parking lot guidance robot with projective imaging capability. This guidance robot receives signals from available parking spaces within the parking lot via a signal receiving module, processes and organizes these signals through a data processing module, plans a route, and transmits the planned route to a control box. It then moves via a drive wheel set and projects indicators onto the ground using three projection lights located at the rear of the control box, making it easier for drivers to see the route.
[0004] However, the guide robot designed in the above technical solution occupies a large area of the road surface. Therefore, when the parking lot is in peak use, the guide robot is very likely to collide with passing vehicles and pedestrians. At the same time, occupying the lane will also affect the normal passage of vehicles in the parking lot. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated parking guidance vehicle.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automated guided vehicle (AGV) for parking lots includes a support rod and bearings mounted on the outer walls of support columns on both sides of a lane intersection. A circular stop is fixed to the top outer wall of the support rod, and an annular groove is formed on the outer wall of the circular stop. An electric telescopic rod is fixed to the outer wall of the bearings. A connecting plate is fixed to the output shaft of the electric telescopic rod. A first rotating shaft is rotatably connected to the inner wall of the connecting plate. An arc-shaped stop is fixed to the bottom end of the first rotating shaft. An arc-shaped insert is fixed to the inner wall of the arc-shaped stop and is inserted into the inner wall of the annular groove. A control panel is fixed to the outer wall of the support rod. A roller is rotatably connected to the bottom inner wall of the support rod. A drive motor is fixed to the outer wall of the support rod. The output shaft of the drive motor is connected to the roller via a transmission belt. The drive motor and the control panel are electrically connected.
[0008] The first rotating shaft and the outer wall of the support column are provided with a transmission mechanism, and support plates are fixed at both ends of the support rod. A set of guide wheels are rotatably connected to the bottom outer wall of the support plate.
[0009] Preferably, a fixing plate is fixed to the outer wall of the support column, and a guide wheel is rotatably connected to the top outer wall of the fixing plate;
[0010] The outer wall of one side of the support column located on both sides of the lane intersection has a reserved groove, and a servo motor is fixed to the inner wall of the top of the reserved groove. The output shaft of the servo motor is fixed with a rotating plate.
[0011] Furthermore, the outer wall of the fixing plate is fixed with multiple indicator lights and ultrasonic sensors corresponding to the parking spaces.
[0012] A further preferred embodiment: the transmission mechanism includes a second rotating shaft, a gear, a transmission chain, and a gear disc. The gear disc is fixed to the outer wall of the support column. The second rotating shaft is rotatably connected to the top outer wall of the electric telescopic rod. The gear is fixed to the outer wall of the second rotating shaft. The transmission chain is connected to the outer walls of the second rotating shaft and the first rotating shaft via a sprocket. The circumference of the gear disc is twice that of the gear.
[0013] As a preferred embodiment of the present invention: an L-shaped plate is fixed to the top outer wall of the electric telescopic rod, an airbag is fixed to the outer wall of the L-shaped plate, and one end of the airbag is fixed to one side of the outer wall of the connecting plate.
[0014] As a further preferred embodiment of the present invention: a cylinder is fixed to the top outer wall of the electric telescopic rod, an extension plate is fixed to the output end of the cylinder, a tension wheel is rotatably connected to the top outer wall of the extension plate, the outer wall of the tension wheel is connected to the transmission chain via a link, and the other end of the airbag is connected to the input end of the cylinder via an air guide pipe.
[0015] As a further embodiment of the present invention: connecting rods are fixed to the outer walls of adjacent sides of the support column, and magnet blocks are fixed to the outer walls of the connecting rods.
[0016] Based on the aforementioned scheme: extension plates are fixed to the outer walls on both sides of the support rod, and casters are fixed to the bottom outer walls of the extension plates.
[0017] Based on the aforementioned scheme, the preferred embodiment is as follows: a mounting plate is fixed to one side of the outer wall of the support rod, a warning light is fixed to the outer wall of the mounting plate, and the warning light is electrically connected to the control panel.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. This invention only requires controlling the drive motor to rotate the rollers in both directions. Guided by the arc-shaped blocks extending from the outer wall of the support column at the intersection, the support rod can turn and move straight according to navigation data. The column-shaped guide vehicle only needs to occupy the middle lane area of the road to move and return within the parking lot according to the navigation route. While effectively guiding vehicles, it will not affect the normal driving of other vehicles in the parking lot, thereby improving the efficiency of vehicle guidance in the parking lot.
[0020] 2. The control terminal only needs to control whether the electric telescopic rod corresponding to the outer wall of the support column pushes the arc-shaped stop forward according to the map navigation data. Pushing the corresponding arc-shaped stop forward indicates that the guide vehicle needs to turn left or right at this intersection. Not pushing the arc-shaped stops on both sides of the intersection forward indicates that the arc-shaped stops at the intersection will not obstruct the circular stops, indicating that the guide vehicle needs to go straight at this intersection. Therefore, the control terminal only needs to control the electric telescopic rod of the corresponding intersection to complete the driving route control of the guide vehicle.
[0021] 3. When the electric telescopic rod rotates around the support column under the push of the support rod, the gear located on the outer wall of the second rotating shaft will also rotate around the gear plate. Thus, while the electric telescopic rod rotates 90 degrees, it drives the gear and the second rotating shaft to rotate 180 degrees, thereby driving the first rotating shaft to rotate 180 degrees. According to the steering requirements of the support rod, the orientation of the arc-shaped stop opening is changed, so that the support rod can stably complete a 90-degree turn under the guidance of the circular stop and the arc-shaped stop.
[0022] 4. When the electric telescopic rod pushes the arc-shaped stop outward to block the support rod, the connecting plate located on the outer wall of the electric telescopic rod's output shaft will cause the airbag to stretch, thereby drawing the gas inside the cylinder into the airbag through the air guide pipe. At this time, the cylinder's output shaft will drive the tension wheel to move back, allowing the tension wheel to continuously tension the transmission chain that has been stretched after moving with the first rotating shaft. When the electric telescopic rod finishes blocking and guiding the support rod and resets, the airbag will contract under the push of the connecting plate, thereby filling the cylinder with internal gas, causing the cylinder to push the tension wheel outward, allowing the tension wheel to continuously tension the transmission chain that has been compressed and contracted after moving with the first rotating shaft, ensuring that the transmission connection between the second rotating shaft and the first rotating shaft remains stable.
[0023] 5. When the warning light is on, it can remind vehicles at the intersection that the support pole is about to go straight or turn through the intersection. Usually, when the support pole goes straight or turns through the intersection, it will not affect vehicles turning right at the intersection. Vehicles that need to turn left or go straight only need to wait for the support pole to complete the turn or go straight through the intersection before they can pass normally.

[0034] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] Example 1:
[0037] An automated guided vehicle for parking lots, such as Figure 1-9 As shown, the system includes a support rod 1 and bearings 14 mounted on the outer walls of support columns 4 on both sides of the intersection of lanes 2. A circular stop 19 is fixed to the top outer wall of the support rod 1, and an annular groove 18 is formed on the outer wall of the circular stop 19. An electric telescopic rod 9 is fixed to the outer wall of the bearing 14. A connecting plate 25 is fixed to the output shaft of the electric telescopic rod 9. A first rotating shaft 23 is rotatably connected to the inner wall of the connecting plate 25. An arc-shaped stop 20 is fixed to the bottom end of the first rotating shaft 23. An arc-shaped insert 21 is fixed to the inner wall of the arc-shaped stop 20 and is inserted into the inner wall of the annular groove 18. A control panel 7 is fixed to the outer wall of the support rod 1. A roller 36 is rotatably connected to the bottom inner wall of the support rod 1. A drive motor 17 is fixed to the outer wall of the support rod 1. The output shaft of the drive motor 17 is connected to the roller 36 via a transmission belt. The drive motor 17 is electrically connected to the control panel 7.
[0038] The first rotating shaft 23 and the outer wall of the support column 4 are provided with a transmission mechanism. Support plates 8 are fixed at both ends of the support rod 1. A set of guide wheels 10 are rotatably connected to the bottom outer wall of the support plate 8.
[0039] A fixing plate 6 is fixed to the outer wall of the support column 4, and a guide wheel 10 is rotatably connected to the top outer wall of the fixing plate 6.
[0040] A reserved groove 34 is opened on one side of the outer wall of the support column 4 located on both sides of the intersection of lane 2. A servo motor 35 is fixed on the top inner wall of the reserved groove 34, and a rotating plate 5 is fixed on the output shaft of the servo motor 35.
[0041] The outer wall of the fixing plate 6 is fixed with multiple indicator lights 13 and ultrasonic sensors 33 corresponding to the parking spaces 3;
[0042] The servo motor 35, electric telescopic rod 9, indicator light 13 and ultrasonic sensor 33 are respectively connected to the control terminal in the internal computer room of the parking lot. The control panel 7 is connected to the control terminal via a wireless network. A battery is installed on the inner wall of the support rod 1 to power the control panel 7 and drive motor 17 on the support rod 1.
[0043] Multiple ultrasonic sensors 33 located on the outer wall of the fixed plate 6, corresponding to parking spaces, can monitor the usage of parking spaces inside the parking lot in real time and transmit the location and number of empty parking spaces to the control terminal in real time. When a vehicle enters the parking lot through the entrance gate, the support rod 1 will display the number of empty parking spaces in the parking lot, so that car owners can know whether there are enough empty spaces in the parking lot.
[0044] When the ultrasonic sensor 33 detects that the number of empty parking spaces is less than 10-15% of the total number of parking spaces, it indicates that vehicles entering the parking lot will need to detour for a long time to find an empty parking space. At this time, after the vehicle enters the parking lot through the parking lot gate, the gate will close first to prevent the following vehicles from continuously entering the parking lot. Then, the control terminal will select the empty parking space closest to the parking lot entrance as the target parking space based on the location of the empty parking space detected by the ultrasonic sensor 33. Then, based on the map of the lane 2 inside the parking lot, the shortest route navigation will be planned and the navigation data will be transmitted to the control panel 7. Then, the control panel 7 will display a prompt message on the screen reminding the driver to follow the support rod 1. Then, based on the road navigation data, the control panel 7 will control the drive motor 17 to drive the roller 36 to rotate, thereby driving the support rod 1 to move forward under the support of the two side support plates 8, guide wheels 10 and fixed plates 6. At the same time, the control terminal will control the electric telescopic rods 9 on the outer walls of the bearings 14 on both sides of the intersection in front of the support rod 1 according to the specified navigation route.
[0045] like Figure 7-8 As shown, when support rod 1 passes through the intersection and three-way intersection inside the parking lot, according to the navigation data, when support rod 1 needs to turn to one side of the road, the control terminal controls the electric telescopic rod 9 on the outer wall of the support column 4 on the same side as the direction support rod 1 needs to turn to push the connecting plate 25 forward a corresponding distance before controlling the drive motor 17 on the control panel 7. This allows the arc-shaped stop 20 on the corresponding side of the support column 4 to block in front of the circular stop 19 at the top of support rod 1. When support rod 1 moves to the corresponding intersection, the circular stop 19 at the top will insert into the corresponding arc-shaped stop 20, thereby guiding the electric telescopic rod 9 and the bearing 14. Downward, rotating around the corresponding support column 4 towards the intersection side, after the support rod 1 moves 90 degrees in an arc under the guidance of the circular stop 19 and the electric telescopic rod 9, the transmission mechanism located on the outer wall will drive the arc-shaped stop 20 to rotate 180 degrees, so that the opening direction of the arc-shaped stop 20 rotates to the direction in which the support rod 1 moves forward at this time. Thus, after the support rod 1 moves 90 degrees in an arc, the arc-shaped stop 20 is released from the obstruction of the circular stop 19, allowing the support rod 1 to rotate from the original middle position of the straight road to the middle position of the road on the corresponding side of the intersection, so that the support rod 1 with the upright shape can complete the road turning inside the parking lot according to the navigation data;
[0046] When support rod 1 needs to pass through the corresponding intersection according to navigation data, the control terminal will control the servo motors 35 on the inner walls of the support columns 4 on both sides of the intersection to drive the rotating plate 5 to rotate to the same angle as the forward direction of support rod 1, such as... Figure 7 As shown in the rotating plate 5 on the left, the rotating plate 5 can continuously support the support plates 8 and guide wheels 10 on both sides of the support rod 1 as it moves forward through the intersection, thereby improving the stability of the support rod 1 when it passes through the intersection. When the support rod 1 needs to turn at the intersection according to the navigation data, the control terminal will control the servo motor 35 inside the support column 4 on the corresponding side to drive the rotating plate 5 to rotate 90 degrees to the corresponding side, thereby supporting the support plates 8 and guide wheels 10 on both sides of the support rod 1 after the turn.
[0047] Once the support rod 1 moves to the side of the empty parking space under the guidance of the navigation data, the vehicle can be guided. At this time, the control panel 7 will control the drive motor 17 to drive the roller 36 to rotate in the opposite direction, thereby driving the support rod 1 to return along the original route. Since the extended electric telescopic rod 9 and the arc-shaped stop 20 have already rotated 90 degrees and 180 degrees under the push of the support rod 1 when they moved before, when the support rod 1 returns along the original route, the circular stop 19 at the top of the support rod 1 will also insert into the arc-shaped stop 20 after being docked, thus pushing the electric telescopic rod 9 back. While rotating and resetting, the support rod 1 moves back in an arc shape under the guidance of the electric telescopic rod 9 and the bearing 14. The control panel 7 only needs to control the drive motor 17 to drive the roller 36 to rotate in both directions. Under the guidance of the arc-shaped stop block 20 extending from the outer wall of the support column 4 at the intersection, the support rod 1 can turn and go straight according to the navigation data. The support rod 1 only needs to occupy the middle lane area of the road to move and return according to the navigation route within the parking lot road. While effectively guiding vehicles, it will not affect the normal driving of other vehicles in the parking lot, thereby improving the vehicle guidance efficiency of the parking lot.
[0048] After the support rod 1 returns to its initial position at the entrance of the parking lot under the drive of the drive motor 17, the control terminal will control the barrier gate to open, so that the support rod 1 can continue to guide the next vehicle according to the above process. When the vacancy rate inside the parking lot exceeds 15%, the support rod 1 can stop in place and no longer needs to guide vehicles entering the parking lot. It is only necessary to play the corresponding vacancy information on the control panel 7.
[0049] When this guiding robot is used in an underground parking lot, the support column 4 can be a support column that already exists in the parking lot. When this guiding robot is used in an above-ground parking lot, the corresponding number of support columns 4 need to be installed at intersections and on both sides of the road according to the internal road conditions of the parking lot.
[0050] like Figure 3-5As shown, the transmission mechanism includes a second rotating shaft 30, a gear 12, a transmission chain 24, and a gear disc 11. The gear disc 11 is fixed to the outer wall of the support column 4. The second rotating shaft 30 is rotatably connected to the top outer wall of the electric telescopic rod 9. The gear 12 is fixed to the outer wall of the second rotating shaft 30. The transmission chain 24 is connected to the outer walls of the second rotating shaft 30 and the first rotating shaft 23 via a sprocket. The circumference of the gear disc 11 is twice that of the gear 12. When the electric telescopic rod 9 rotates around the support column 4 under the push of the support rod 1, the gear 12 located on the outer wall of the second rotating shaft 30 will also rotate around the gear disc 11. Thus, while the electric telescopic rod 9 rotates 90 degrees, it drives the gear 12 and the second rotating shaft 30 to rotate 180 degrees, thereby driving the first rotating shaft 23 to rotate 180 degrees. The orientation of the arc-shaped stop 20 opening is changed according to the steering requirements of the support rod 1, so that the support rod 1 can stably complete a 90-degree turn under the guidance of the circular stop 19 and the arc-shaped stop 20.
[0051] like Figure 2-4 As shown, an L-shaped plate 28 is fixed to the top outer wall of the electric telescopic rod 9, and an airbag 26 is fixed to the outer wall of the L-shaped plate 28. One end of the airbag 26 is fixed to one side outer wall of the connecting plate 25.
[0052] A cylinder 29 is fixed to the top outer wall of the electric telescopic rod 9. An extension plate 37 is fixed to the output end of the cylinder 29. A tension wheel 27 is rotatably connected to the top outer wall of the extension plate 37. The outer wall of the tension wheel 27 is connected to the transmission chain 24 via a link. The other end of the airbag 26 is connected to the input end of the cylinder 29 via an air guide pipe.
[0053] When the electric telescopic rod 9 pushes the arc-shaped stop 20 outward to block the support rod 1, the connecting plate 25 located on the outer wall of the output shaft of the electric telescopic rod 9 will cause the air bag 26 to stretch, thereby drawing the gas inside the cylinder 29 into the air bag 26 through the air guide pipe. At this time, the output shaft of the cylinder 29 will drive the tension wheel 27 to move back, so that the tension wheel 27 can continuously tension the transmission chain 24 that has been stretched after moving with the first rotating shaft 23. When the electric telescopic rod 9 ends its blocking and guidance of the support rod 1 and resets, the air bag 26 will contract under the push of the connecting plate 25, thereby filling the cylinder 29 with the internal gas, causing the cylinder 29 to push the tension wheel 27 outward, so that the tension wheel 27 can continuously tension the transmission chain 24 that has been squeezed and contracted after moving with the first rotating shaft 23, so that the transmission connection between the second rotating shaft 30 and the first rotating shaft 23 remains stable.
[0054] like Figure 2-5As shown, connecting rods 15 are fixed to the outer walls of adjacent sides of the support column 4, and magnet blocks 16 are fixed to the outer walls of the connecting rods 15. The magnet blocks 16 can attract the outer wall of the electric telescopic rod 9 that has been rotated to one side, thereby improving the stability of the electric telescopic rod 9 after it has been rotated to the corresponding side of the support column 4. The electric telescopic rod 9 can be made of metal, or a metal plate can be added to the corresponding side of the electric telescopic rod 9 so that the magnet blocks 16 can limit the electric telescopic rod 9 through magnetic force.
[0055] like Figure 6 As shown, extension plates 37 are fixed to the outer walls of both sides of the support rod 1, and universal wheels 38 are fixed to the bottom outer walls of the extension plates 37. The universal wheels 38 can support the support rod 1 as a whole when moving back and forth, and cooperate with the support plates 8 on both sides of the support rod 1 to support and guide the support rod 1 when moving.
[0056] In this embodiment, the control terminal set in the parking lot machine room can be an intelligent computer capable of running map navigation software and signal data processing software. The intelligent computer only needs to control whether the electric telescopic rod 9 corresponding to the outer wall of the support column 4 pushes the arc-shaped stop 20 forward according to the map navigation data. Pushing the corresponding arc-shaped stop 20 forward indicates that the guide vehicle needs to turn left or right at this intersection. Not pushing the arc-shaped stop 20 on both sides of the intersection forward indicates that the arc-shaped stop 20 at the intersection will not block the circular stop 19, indicating that the guide vehicle needs to go straight at the intersection. Therefore, the intelligent computer only needs to control the electric telescopic rod 9 at the corresponding intersection to complete the driving route control of the guide vehicle.
[0057] In this embodiment, the control terminal selects the nearest available parking space to the parking lot entrance as the target parking space based on the location of the available parking space detected by the ultrasonic sensor 33. Then, based on the map of the lane 2 inside the parking lot, it plans the shortest route for navigation and transmits the navigation data to the control panel 7. The control panel 7 then displays a prompt message on the screen reminding the driver to follow the support rod 1. Subsequently, the control panel 7 controls the drive motor 17 to rotate the roller 36 based on the road navigation data, thereby moving the support rod 1 forward under the support of the two side support plates 8, guide wheels 10 and fixed plate 6. At the same time, the control terminal controls the electric telescopic rods 9 on the outer walls of the bearings 14 on both sides of the intersection in front of the support rod 1 according to the specified navigation route.
[0058] When the support rod 1 passes through the crossroads and three-way intersections inside the parking lot, before the control terminal controls the drive motor 17 to run on the control panel 7, it controls the electric telescopic rod 9 on the outer wall of the support column 4 on the same side as the direction the support rod 1 needs to turn to push the connecting plate 25 forward by a corresponding distance, so that the arc-shaped stop 20 on the side of the corresponding support column 4 blocks in front of the circular stop 19 at the top of the support rod 1.
[0059] When the support rod 1 moves to the corresponding intersection, the circular stop 19 at the top will insert into the corresponding arc-shaped stop 20. Under the guidance of the corresponding electric telescopic rod 9 and bearing 14, it will rotate around the corresponding support column 4 towards the intersection. After the support rod 1 moves 90 degrees in an arc under the guidance of the circular stop 19 and the electric telescopic rod 9, the transmission mechanism on the outer wall will drive the arc-shaped stop 20 to rotate 180 degrees, so that the opening direction of the arc-shaped stop 20 rotates to the direction in which the support rod 1 moves forward. After the support rod 1 moves 90 degrees in an arc, the arc-shaped stop 20 will stop the circular stop 19, allowing the support rod 1 to rotate from the original middle position of the straight road to the middle position of the road on the corresponding side of the intersection, so that the support rod 1 with the upright shape can complete the road turning inside the parking lot according to the navigation data.
[0060] When the support rod 1 needs to pass through the corresponding intersection according to the navigation data, the control terminal will control the servo motor 35 on the inner wall of the support column 4 on both sides of the intersection to drive the rotating plate 5 to rotate to the same angle as the forward direction of the support rod 1, so that the rotating plate 5 can continuously support the support plate 8 and guide wheel 10 on both sides of the support rod 1 as it passes through the intersection.
[0061] Once the support rod 1 moves to the side of the empty parking space under the guidance of the navigation data, the vehicle can be guided. At this time, the control panel 7 will control the drive motor 17 to drive the roller 36 to rotate in the opposite direction, causing the support rod 1 to return along the original route. When the support rod 1 returns along the original route, the circular stop 19 at the top of the support rod 1 will also insert into the previously connected arc-shaped stop 20. While pushing the electric telescopic rod 9 to rotate back and reset, the support rod 1 moves back in an arc shape under the guidance of the electric telescopic rod 9 and the bearing 14. The control panel 7 only needs to control the drive motor 17 to drive the roller 36 to rotate in both directions. Under the guidance of the arc-shaped stop 20 extending from the outer wall of the support column 4 at the intersection, the support rod 1 can turn and go straight according to the navigation data. The support rod 1 only needs to occupy the middle lane area of the road to move and return according to the navigation route within the parking lot road.
[0062] Example 2:
[0063] An automated guided vehicle for parking lots, such as Figure 4 As shown, this embodiment makes the following improvements based on embodiment 1: A mounting plate 31 is fixed to one side of the outer wall of the support rod 1, and a warning light 32 is fixed to the outer wall of the mounting plate 31. The warning light 32 is electrically connected to the control panel 7. When the warning light 32 is lit, it can remind vehicles at the intersection that the support rod 1 is about to go straight or turn through the intersection. Usually, when the support rod 1 goes straight or turns through the intersection, it will not affect vehicles turning right at the intersection. Vehicles that need to turn left or go straight only need to wait for the support rod 1 to complete the turn or go straight through the intersection before they can pass normally.
[0064] In this embodiment, when the warning light 32 is lit, it can remind vehicles at the intersection that the support pole 1 is about to go straight or turn through the intersection.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
