Description

Technical Field

[0001] The present invention relates to the technical field of intelligent vehicle management in parking lots, and particularly to an unattended parking lot management system and its equipment. Background Art

[0002] With the continuous improvement of the living standards of the people in our country, cars, as basic means of transportation, have gradually entered thousands of households. In order to meet people's travel needs, a large number of parking lots need to be set up in cities. In order to save operating costs, most of these parking lots are managed in an unattended manner. However, the existing parking lot vehicle management system has a low degree of intelligence and cannot determine the parking distribution and vehicle positions in the parking lot, which brings many inconveniences in parking lot management and vehicle owners' search for their vehicles.

[0003] After retrieval, a patent with the Chinese patent application number CN202310033077.8 discloses a parking information statistics robot for a parking lot, including a chassis, a traveling mechanism installed on the chassis, a frame fixedly connected to the top surface of the chassis, and a camera fixedly installed on one side of the frame. However, due to the relatively large overall structure of the robot, it will occupy a large amount of road area when moving, and it is easy to block the vehicles entering and leaving the parking lot during the peak hours of vehicle entry and exit in the parking lot. Therefore, there is also a problem that it is easy to affect the normal driving of the vehicles inside the parking lot. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an unattended parking lot management system and its equipment.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An unattended parking lot management device includes a first mounting plate, a second mounting plate, and a third mounting plate. Second connecting plates are respectively fixed to the outer walls on both sides of the second mounting plate, first connecting plates are respectively fixed to the outer walls on the opposite sides of the first mounting plate and the third mounting plate, and the second connecting plates are fixed to the inner walls of the first connecting plates by screws;

[0007] A stepping motor is fixed to the inner wall of the second mounting plate. The output shaft of the stepping motor is connected to a second rotating rod through a coupling. The first rotating rod and the third rotating rod are respectively rotatably connected to the bottom outer walls of the first mounting plate and the third mounting plate, and the second rotating rod is in transmission connection with the first rotating rod and the third rotating rod respectively through a transmission chain;

[0008] Friction discs are respectively rotatably connected to the outer walls of the bottoms of the second rotating rod, the first rotating rod, and the third rotating rod. Guide cylinders are respectively slidably connected to the outer walls of the second rotating rod, the first rotating rod, and the third rotating rod. Fixed plates are fixed to the outer walls of the guide cylinders. Moving mechanisms are arranged on the outer walls on both sides of the fixed plates. Slots are formed in the inner walls of the guide cylinders. Insert bars are respectively formed on the outer walls of the second rotating rod, the first rotating rod, and the third rotating rod. Connecting bearings are rotatably connected to the outer walls of the second rotating rod, the first rotating rod, and the third rotating rod. A group of connecting rods are fixed to the outer walls of the connecting bearings.

[0009] Preferably: An electric push rod is fixed to the outer wall of the top of the fixed plate. A push plate is arranged on the outer wall of the output shaft of the electric push rod. The push plate is arranged on the outer wall of the bottom of the connecting rod.

[0010] Furthermore: The moving mechanism includes connecting pieces, rotating shafts, rotating frames, electric wheels, and fixed pulleys. The connecting pieces are respectively fixed to the outer walls on both sides of the fixed plate. The rotating shafts are fixed to the outer walls on one side of the connecting pieces. The rotating frames are fixed to the outer walls of the rotating shafts. The fixed pulleys and the electric wheels are respectively fixed to the outer walls of the bottoms of the rotating frames.

[0011] More preferably: A control box is fixed to the outer wall of the second mounting plate. The stepping motor, the electric push rod, and the electric wheel are respectively electrically connected to the control box.

[0012] As a preferred embodiment of the present invention: Network cameras are respectively fixed to the outer walls of the second rotating rod, the first rotating rod, and the third rotating rod. The network cameras are in communication connection with the control box.

[0013] As a further preferred embodiment of the present invention: A rack plate is fixed to the outer wall on one side of the connecting rod. The rack plate is slidably connected to the outer walls on both sides of the fixed plate. A toothed ring is fixed to the outer wall of the rotating shaft. The rack plate is meshed with the toothed ring.

[0014] As a further solution of the present invention: A group of L-shaped support plates are fixed to the outer wall of the bottom of the fixed plate.

[0015] On the basis of the foregoing solution: A group of support frames are fixed to the outer wall of the bottom of the fixed plate. The height of the support frames is less than the height of the fixed pulleys and the electric wheels. A smooth contact surface is formed on the outer wall of the bottom of the support frames.

[0016] An unattended parking lot management system includes a gate module for controlling vehicle entry and exit, a parking area display module for displaying the remaining number of parking spaces in each area inside the parking lot, and a parking lot internal inspection module for inspecting the inside of the parking lot through parking lot management equipment. The gate module, the parking area display module, and the parking lot internal inspection module are in communication connection with each other.

[0017] The beneficial effects of the present invention are:

[0018] 1. Staff members can adjust and fix the position between the first connecting plate and the second connecting plate according to the specific width of the internal road in the parking lot and the position of the road markings set on the outer wall of the road, so as to adjust the distance between the first rotating rod, the second rotating rod and the third rotating rod, so that the moving mechanisms at the bottoms of the first rotating rod, the second rotating rod and the third rotating rod just support on the road markings on the outer wall of the road. At this time, vehicles on the road can directly pass through the gaps between the first rotating rod, the second rotating rod and the third rotating rod, enabling the parking lot management equipment to always move and patrol inside the parking lot without blocking the vehicles driving on the road, and at the same time, it will not scrape against the vehicles parked inside the parking area during movement, thus improving the operation efficiency of the parking lot management.

[0019] 2. When the management equipment moving on the road needs to turn at an intersection, first, the whole management equipment moves to the middle of the intersection driven by the moving mechanism. At this time, the first rotating rod, the second rotating rod and the third rotating rod are respectively located at the middle position and two diagonal positions of the intersection. Therefore, the management equipment located at the intersection still will not block the vehicles driving at the intersection. Subsequently, the orientation of the moving mechanisms on both sides of the fixed plate is changed through the cooperation of the electric push rod and the stepping motor, so as to quickly complete the turning of the management equipment without affecting the traffic of vehicles at the intersection, enabling the management equipment to move smoothly inside the parking lot.

[0020] 3. When the connecting rod moves downward driven by the first rotating rod, the second rotating rod and the third rotating rod, the rack plates on both sides of the connecting rod will also move downward at the same time, thereby driving the rotating shaft to rotate upward through the meshing gear ring. When the rotating shaft rotates upward, it can drive the rotating frame on the outer wall to rotate upward, so that the electric wheels and fixed pulleys on both sides of the fixed plate are turned upward at the same time, so that the electric wheels and fixed pulleys can be not in contact with the ground when the fixed plate is turning, avoiding the friction between the electric wheels and the ground from affecting the normal turning adjustment of the fixed plate.

[0021] 4. After the electric push rod pushes the connecting rod upward to the preset position, the connecting rod will also drive the first rotating rod, the second rotating rod and the third rotating rod rotatably connected to the inner wall to rise to the corresponding height through the connecting bearing. At this time, the inserts on the outer walls of the first rotating rod, the second rotating rod and the third rotating rod will be completely removed from the slots on the inner wall of the guide cylinder. At this time, the control box can control the stepping motor to drive the second rotating rod to rotate under the support and guidance of the connecting bearing, so as to change the shooting angle of the network cameras set on the outer walls of the first rotating rod, the second rotating rod and the third rotating rod, enabling the network cameras to better identify and shoot the vehicles and parking space information inside the parking lot.

[0022] 5. When the electric wheels and the rotating frame are driven by the rack plate to open to both sides, the fixed plate will continuously move downward due to its own gravity until the support frame at the bottom of the fixed plate contacts the ground. At this time, the support frame can cooperate with the friction disc to support the overall management device. At the same time, the smooth contact surface at the bottom of the support frame can reduce the friction between the support frame and the ground, so that the fixed plate can smoothly complete the turning under the support of the support frame, improving the overall stability of the management device during turning.

Guide cylinders 24 are respectively slidably connected to the outer walls of the second rotating rod 8, the first rotating rod 5, and the third rotating rod 15. A fixing plate 22 is fixed to the outer wall of the guide cylinder 24. Moving mechanisms are arranged on the outer walls on both sides of the fixing plate 22. Slots 27 are formed in the inner walls of the guide cylinders 24. Insert bars 18 are respectively formed on the outer walls of the second rotating rod 8, the first rotating rod 5, and the third rotating rod 15. Connecting bearings 19 are rotatably connected to the outer walls of the second rotating rod 8, the first rotating rod 5, and the third rotating rod 15. A group of connecting rods 30 are fixed to the outer walls of the connecting bearings 19;

[0037] An electric push rod 21 is fixed to the top outer wall of the fixing plate 22. A push plate is arranged on the outer wall of the output shaft of the electric push rod 21. The push plate is arranged on the bottom outer wall of the connecting rod 30.

[0038] The moving mechanism includes connecting pieces 26, rotating shafts 28, rotating frames 16, electric wheels 13, and fixed pulleys 6. The connecting pieces 26 are respectively fixed to the outer walls on both sides of the fixing plate 22. The rotating shafts 28 are fixed to the outer walls of one sides of the connecting pieces 26. The rotating frames 16 are fixed to the outer walls of the rotating shafts 28. The fixed pulleys 6 and the electric wheels 13 are respectively fixed to the bottom outer walls of the rotating frames 16.

[0039] A control box 10 is fixed to the outer wall of the second mounting plate 12. The stepping motor 11, the electric push rod 21, and the electric wheel 13 are respectively electrically connected to the control box 10.

[0040] The outer walls of the second rotating rod 8, the first rotating rod 5 and the third rotating rod 15 are respectively fixed with network cameras 20, and the network cameras 20 are communicatively connected to the control box 10.

[0041] One side outer wall of the connecting rod 30 is fixed with a rack plate 17. The rack plate 17 is slidably connected to the two side outer walls of the fixing plate 22. A gear ring 29 is fixed to the outer wall of the rotating shaft 28, and the rack plate 17 is meshed with the gear ring 29.

[0042] The control box 10 is internally provided with a radar sensor, a positioning sensor, a wireless network transceiver and a single-chip microcomputer.

[0043] Through the first mounting plate 1, the second mounting plate 12, the third mounting plate 14, the first connecting plate 7, the second connecting plate 9, the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15, the parking lot management equipment can be combined into a bracket structure inclined to the vertical road surface. The staff can adjust and fix the position between the first connecting plate 7 and the second connecting plate 9 according to the specific width of the internal road 2 of the parking lot and the position of the road marking 3 provided on the outer wall of the road 2, so as to adjust the distance between the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15, so that the moving mechanisms at the bottoms of the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15 just support on the road marking 3 on the outer wall of the road 2. At this time, the vehicles on the road 2 can directly pass through the gaps between the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15, enabling the parking lot management equipment to always move and patrol inside the parking lot without blocking the vehicles driving on the road 2, and at the same time, it will not rub against the vehicles parked inside the parking area 4 during movement, thereby improving the operation efficiency of the parking lot management.

[0044] When the management device moving on Road 2 needs to turn at an intersection, first, the whole management device moves to the middle of the intersection driven by the moving mechanism. At this time, the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 are respectively located at the middle position and two diagonal positions of the intersection. Therefore, the management device located at the intersection still does not block the vehicles driving at the intersection. Subsequently, the control box 10 controls the electric push rod 21 to drive the push plate on the output shaft to move downward by a corresponding distance, so that the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 as a whole move downward by a corresponding distance under the guidance of the guide cylinder 24 due to their own gravity, and the friction disks 31 rotatably connected to the bottoms of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 contact the ground. Subsequently, the control box 10 controls the stepping motor 11 to drive the second rotating rod 8 to rotate 90 degrees in the direction where the management device needs to move. When the second rotating rod 8 rotates, it can drive the first rotating rod 5 and the third rotating rod 15 to rotate simultaneously through the transmission chain connected to the outer wall, so as to drive the corresponding guide cylinder 24 to rotate through the inserts 18 on the outer walls of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15. When the guide cylinder 24 rotates, it will drive the fixed plate 22 to rotate. At this time, the friction disk 31 can support the rotating first rotating rod 5, second rotating rod 8, and third rotating rod 15 through the friction force with the ground, thereby changing the orientations of the moving mechanisms on both sides of the fixed plate 22. Subsequently, the control box 10 controls the electric push rod 21 to push the push plate upward and reset, thereby driving the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 to move upward, so that the friction disk 31 is away from the ground. Subsequently, the control box 10 controls the electric wheels 13 to run again, so as to quickly complete the turning of the management device without affecting the traffic of vehicles at the intersection, and enable the management device to move smoothly inside the parking lot.

[0045] When the connecting rod 30 moves downward driven by the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15, the rack plates 17 on both sides of the connecting rod 30 also move downward simultaneously, thereby driving the rotating shaft 28 to rotate upward through the gear ring 29 meshed therewith. When the rotating shaft 28 rotates upward, it can drive the rotating frame 16 on the outer wall to rotate upward, so that the electric wheels 13 and the fixed pulleys 6 on both sides of the fixed plate 22 are turned upward simultaneously, so that the electric wheels 13 and the fixed pulleys 6 can be not in contact with the ground when the fixed plate 22 is turning, and avoid the friction force between the electric wheels 13 and the fixed pulleys 6 and the ground from affecting the normal turning adjustment of the fixed plate 22; when the connecting rod 30 moves upward and resets under the push of the electric push rod 21, the rack plate 17 also drives the rotating frame 16 to rotate downward and reset through the rotating shaft 28, so that the electric wheels 13 and the fixed pulleys 6 contact the ground again after the fixed plate 22 turns.

[0046] When the electric push rod 21 pushes the connecting rod 30 upward to a preset position, the connecting rod 30 will also drive the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 rotatably connected to the inner wall to rise to the corresponding height through the connecting bearing 19. At this time, the inserts 18 on the outer walls of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 will be completely removed from the slots 27 on the inner wall of the guiding cylinder 24. At this time, the control box 10 can control the stepping motor 11 to drive the second rotating rod 8 to rotate under the support and guidance of the connecting bearing 19, thereby changing the shooting angle of the network camera 20 provided on the outer walls of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15, so that the network camera 20 can better identify and shoot the vehicles and parking space information inside the parking lot. When the management device needs to turn, the control box 10 will control the stepping motor 11 to drive the second rotating rod 8 to rotate to the initial angle, so that the inserts 18 on the outer walls of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 are aligned with the slots 27 on the inner wall of the guiding cylinder 24 again.

[0047] As Figure 4 shown, a group of L-shaped support plates 25 are fixed on the bottom outer wall of the fixed plate 22; the L-shaped support plates 25 can support and limit the rotating frames 16 unfolded on both sides of the fixed plate 22, and cooperate with the rack plate 17 and the gear ring 29 to support and fix the rotating frames 16.

[0048] As Figure 4-5 shown, a group of support frames 23 are fixed on the bottom outer wall of the fixed plate 22. The height of the support frames 23 is less than the heights of the fixed pulley 6 and the electric wheel 13. A smooth contact surface is provided on the bottom outer wall of the support frames 23; when the electric wheel 13 and the rotating frame 16 are driven by the rack plate 17 to turn to both sides, the fixed plate 22 will continuously move downward due to its own gravity until the support frames 23 at the bottom of the fixed plate 22 contact the ground. At this time, the support frames 23 can cooperate with the friction disc 31 to support the whole management device. At the same time, the smooth contact surface at the bottom of the support frames 23 can reduce the friction between the support frames 23 and the ground, so that the fixed plate 22 can smoothly complete the turning under the support of the support frames 23, and improve the overall stability of the management device when turning.

[0049] When this embodiment is in use, the staff can adjust and fix the positions between the first connecting plate 7 and the second connecting plate 9 according to the specific width of the internal road 2 in the parking lot and the position of the road markings 3 provided on the outer wall of the road 2, so as to adjust the distance between the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15, so that the moving mechanisms at the bottoms of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 just support on the road markings 3 on the outer wall of the road 2. At this time, the vehicles on the road 2 can directly pass through the gaps between the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15.

[0050] When the management device moving on Road 2 needs to turn at an intersection, first, the whole management device moves to the middle of the intersection driven by the moving mechanism. At this time, the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 are respectively located at the middle position and two diagonal positions of the intersection. Therefore, the management device located at the intersection still does not block the vehicles driving at the intersection. Subsequently, the control box 10 controls the electric push rod 21 to drive the push plate on the output shaft to move downward by a corresponding distance, so that the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 as a whole move downward by a corresponding distance under their own gravity under the guidance of the guide cylinder 24, and the friction discs 31 rotatably connected to the bottoms of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 contact the ground;

[0051] Subsequently, the control box 10 controls the stepper motor 11 to drive the second rotating rod 8 to rotate 90 degrees in the direction where the management device needs to move. When the second rotating rod 8 rotates, it can drive the first rotating rod 5 and the third rotating rod 15 to rotate simultaneously through the transmission chain connected to the outer wall. Thus, through the inserts 18 on the outer walls of the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15, the corresponding guide cylinders 24 are driven to rotate. When the guide cylinder 24 rotates, it will drive the fixed plate 22 to rotate. At this time, the friction disc 31 can support the rotating first rotating rod 5, second rotating rod 8, and third rotating rod 15 through the friction force with the ground, thereby changing the orientations of the moving mechanisms on both sides of the fixed plate 22. Subsequently, the control box 10 controls the electric push rod 21 to push the push plate upward and reset, thereby driving the first rotating rod 5, the second rotating rod 8, and the third rotating rod 15 to move upward, making the friction disc 31 away from the ground. Subsequently, the control box 10 controls the electric wheel 13 to run again, so as to quickly complete the turning of the management device without affecting the traffic of vehicles at the intersection.

[0052] When the connecting rod 30 moves downward driven by the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15, the rack plates 17 on both sides of the connecting rod 30 will also move downward simultaneously, thereby driving the rotating shaft 28 to rotate upward through the engaged gear ring 29. When the rotating shaft 28 rotates upward, it can drive the rotating frame 16 on the outer wall to rotate upward, so that the electric wheels 13 and the fixed pulleys 6 on both sides of the fixed plate 22 are turned upward simultaneously, so that the electric wheels 13 and the fixed pulleys 6 can be kept out of contact with the ground when the fixed plate 22 is turning. After the electric push rod 21 pushes the connecting rod 30 upward to a preset position, the connecting rod 30 will also drive the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15 which are rotatably connected to the inner wall to rise to the corresponding height through the connecting bearing 19. At this time, the inserts 18 on the outer walls of the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15 will be completely removed from the slots 27 on the inner wall of the guide cylinder 24. At this time, the control box 10 can control the stepping motor 11 to drive the second rotating rod 8 to rotate under the support and guidance of the connecting bearing 19, so as to change the shooting angle of the network camera 20 arranged on the outer walls of the first rotating rod 5, the second rotating rod 8 and the third rotating rod 15, so that the network camera 20 can better identify and shoot the vehicles and parking space information inside the parking lot.

[0053] Embodiment 2:

[0054] An unattended parking lot management system includes a gate module for controlling the entry and exit of vehicles, a parking area display module for displaying the remaining number of parking spaces in each area inside the parking lot, and a parking lot internal inspection module for inspecting the inside of the parking lot through parking lot management equipment. The gate module, the parking area display module and the parking lot internal inspection module are communicatively connected to each other.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
