Description

Technical Field

[0001] This invention relates to the field of automated parking system technology, specifically a rear-row forward-moving PSH parking system. Background Technology

[0002] In recent years, with the rapid development of the automotive industry, the per capita ownership of cars has been continuously increasing, but the growth in the number of parking spaces has been relatively slow, leading to increasingly prominent parking problems, especially in bustling urban areas, residential communities, and large shopping malls. To meet the growing parking demand, various forms of multi-level parking garages have been developed. Multi-level parking garages typically have upper and lower parking platforms. Often, the upper platform is lowered first, a vehicle drives in, and then it rises again, allowing the lower platform to be used for the next vehicle. However, this makes it difficult to retrieve vehicles already in the upper platform laterally. To address this, some existing parking systems use a lateral sliding method for the parking platforms and a drive-out method for the lower platform. However, the lateral sliding method leaves one row of vehicles unusable, resulting in low efficiency. The drive-out method requires a large area, and moving vehicles within the limited internal pathways of underground garages can cause congestion, severely impacting vehicle access during peak hours. Its applicability is poor, and the cost of two parking platforms is high, with safety being difficult to guarantee. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a rear-row forward-moving PSH parking device to solve the problems mentioned in the background art.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A rear-row forward-moving PSH parking device includes two sets of mirror-symmetrical lifting modules and steering modules. The lifting module includes a bottom movable bracket, a guide column, a rotating support column, a movable frame, and a telescopic frame. The steering module includes a support crossbeam and a parking frame.

[0006] The bottom movable support is movable. The guide column is welded to the upper surface of the bottom movable support. A first mounting box is fixedly connected to one side of the guide column, and a second mounting box is fixedly connected to the top of the guide column. A rotating support column, a tie rod, a first hydraulic rod, and a second hydraulic rod are provided on the other side of the guide column. A movable frame is provided on the side of the guide column and the rotating support column. The first hydraulic rod and the second hydraulic rod drive the rotating support column to rotate. The rotating support column drives the first support wheel to push the movable frame to rotate. The tie rod drives the movable frame to change height along the guide column when rotating.

[0007] The mobile frame is equipped with a movable telescopic frame on one side, and a support crossbeam is installed between the two sets of telescopic frames. Both sides of the support crossbeam are welded to the telescopic frames, and a rotatable parking frame is provided above the support crossbeam.

[0008] Preferably, the bottom movable support runs underground in the underground parking garage. The lower end of the bottom movable support is provided with an array of rollers. The rollers slide in cooperation with the slide rails underground, and the bottom movable support is moved along the slide rails by a chain.

[0009] Preferably, the guide column has a cavity inside, the tail end of the movable frame has a welded blocking frame, the upper end of the movable frame has a rotatably connected support shaft, the support shaft has a rotatably connected guide wheel, and the guide wheel rolls inside the cavity of the guide column.

[0010] Preferably, the first mounting box is provided with a first electric cylinder and a slidable first limiting block fixedly connected inside. The driving end of the first electric cylinder is fixedly connected to the first limiting block. The first electric cylinder pulls the first limiting block in and out of the first mounting box and through the internal cavity of the guide column to block the internal cavity of the guide column.

[0011] Preferably, the second mounting box is provided with a telescopic column and a linear displacement sensor that are fixedly connected. A spring is sleeved on the outside of the telescopic column, and a second limiting block is fixedly connected to the telescopic end of the telescopic column. The telescopic measuring end of the linear displacement sensor is fixedly connected to the second limiting block. When the second limiting block is pushed up, the telescopic measuring end of the linear displacement sensor retracts and measures the movement of the second limiting block.

[0012] Preferably, one end of the rotating support column is rotatably connected to the guide column, and the other end of the rotating support column is provided with a first support wheel that is rotatably connected. The first support wheel is tangent to the lower end of the movable frame. One end of the pull rod is rotatably connected to the rotating support column, and the other end of the pull rod is rotatably connected to the support shaft. The tail end of the first hydraulic rod is rotatably connected to the bottom movable bracket, and the telescopic end of the first hydraulic rod is rotatably connected to the rotating support column. The tail end of the second hydraulic rod is rotatably connected to the guide column, and the telescopic end of the second hydraulic rod is rotatably connected to the rotating support column.

[0013] Preferably, a fixedly connected support frame is provided on one side of the mobile frame, and a second support wheel is arranged in an array inside the support frame for rotational connection, with the lower end of the telescopic frame tangent to the second support wheel.

[0014] Preferably, the movable frame is provided with an array of drive shafts, and a first motor is fixedly connected to the other side of the movable frame. The first motor shaft is fixedly connected to a group of drive shafts through a coupling. An array of synchronous sprockets is fixedly provided on the drive shafts. The synchronous sprockets are rotated and connected by a synchronous chain, so that all drive shafts can rotate synchronously clockwise or counterclockwise.

[0015] Each drive shaft is also equipped with a fixedly connected drive wheel. The drive wheel is tangent to the inner wall of the telescopic frame. When the drive shaft rotates, it drives the drive wheel to rotate synchronously, thereby driving the telescopic frame to move and extend.

[0016] Preferably, when the telescopic frame moves and extends, it drives the supporting crossbeam to move synchronously. The supporting crossbeam is provided with an array of third support wheels below it. The upper surface of the supporting crossbeam is provided with a turntable bearing and a second motor. The outer ring of the turntable bearing is fixedly connected to the supporting crossbeam. The second motor is connected to a right-angle reducer. The lower surface of the parking frame is fixedly connected to the inner ring of the turntable bearing. The lower end of the parking frame is provided with a fixedly connected rotating frame. The rotating shaft of the right-angle reducer is fixedly connected to the center of the rotating frame. One end of the parking frame is provided with an inclined guide plate, and the other end of the parking frame is provided with an inclined limiting block.

[0017] The beneficial effects of this invention are:

[0018] The parking equipment of this invention effectively solves the parking defects of existing tilting parking equipment, allowing vehicles to be stored and retrieved on both the upper and lower levels of the parking equipment. Furthermore, when retrieving a vehicle from the upper level, there is no need to move the vehicle below, effectively improving the storage rate and applicability, without increasing the overall footprint.

[0019] The parking equipment of this invention adopts a single parking frame structure design, which effectively reduces the cost of use. The parking frame can be raised, lowered and angled. The first hydraulic rod and the second hydraulic rod drive the rotating support column to rotate. The rotating support column drives the first support wheel to push the moving frame to rotate. The pull rod drives the moving frame to change height along the guide column when rotating. The moving frame drives the parking frame to move synchronously. The movement of the parking frame adopts a single power design, avoiding the conventional use of motors and hydraulic rods, reducing the application complexity and subsequent maintenance complexity of the parking equipment.

[0020] The parking equipment of this invention has high safety. The movement of the parking rack is driven by dual hydraulic rods, avoiding the single hydraulic rod drive structure design of existing parking equipment. This also avoids the situation where the parking equipment cannot operate and the car tilts if one set of hydraulic rods fails. When the parking rack is at its lowest point, the third support wheel at the lower end of the support crossbeam provides support. When the parking rack reaches its highest point, the second limit block and the linear displacement sensor determine the movement height, and the first limit block protects the height of the parking rack to prevent it from falling.

[0021] This invention provides a parking device with multiple usage modes, effectively facilitating vehicle storage and retrieval without causing interference. The entire parking device is movable, allowing the parking rack and vehicle to be moved and repositioned, effectively avoiding vehicles parked below. When the parking device moves to the internal road of the garage, the parking rack lowers the vehicle to its lowest point. After the moving rack is level with the ground, the third support wheel contacts the ground, and the telescopic frame, support crossbar, parking rack, and vehicle extend forward. The third support wheel provides support during the movement. The telescopic frame stops at its longest point. The structural design of the parking device fully considers the limitations of the internal roads of the underground garage. When the telescopic frame is fully extended, the vehicle cannot exit the parking rack. At this point, the parking rack can rotate to adjust the vehicle's exit direction, preventing traffic congestion. Attached Figure Description

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0036] Please see Figures 1 to 11 As shown, this embodiment provides a rear-row forward-moving PSH parking device. The parking device includes two sets of mirror-symmetrical lifting modules and steering modules. The lifting modules drive the steering modules to move. The lifting modules include a bottom moving bracket 1, a guide column 2, a rotating support column 3, a moving frame 4, and a telescopic frame 5. The steering modules include a support crossbeam 6 and a parking frame 7.

[0037] Specifically, the bottom movable support 1 runs under the ground of the underground garage. The underground garage has a ground groove, and a fixedly connected slide rail 13 is provided in the ground groove. A rotatably connected sprocket 14 is provided on the side of the slide rail 13. A meshing chain 15 is provided on the sprocket 14. The internal motor drives the sprocket 14 to rotate, thereby driving the chain 15 to rotate synchronously.

[0038] The bottom movable support 1 is provided with an array of rollers 11 at its lower end. The rollers 11 slide in cooperation with the slide rail 13. The bottom movable support 1 is also provided with a fixedly connected drive connecting block 12 at its lower end. The drive connecting block 12 is fixedly connected to the chain 15. When the chain 15 rotates, it pulls the bottom movable support 1 to move along the slide rail 13.

[0039] Furthermore, the bottom movable support 1 is provided with a welded guide column 2 at the upper end, the guide column 2 has a cavity inside, and a first mounting box 21 is fixedly connected to one side of the guide column 2;

[0040] Specifically, the top of the guide column 2 is provided with a second mounting box 22 that is fixedly connected. The first mounting box 21 is provided with a first electric cylinder 211 and a sliding first limiting block 212 that are fixedly connected. The driving end of the first electric cylinder 211 is fixedly connected to the first limiting block 212. The first electric cylinder 211 pulls the first limiting block 212 in and out of the first mounting box 21 and through the internal cavity of the guide column 2 to block the internal cavity of the guide column 2.

[0041] The second mounting box 22 contains a telescopic column 221 and a linear displacement sensor 224 that are fixedly connected. A spring 222 is sleeved on the outside of the telescopic column 221. A second limiting block 223 is fixedly connected to the telescopic end of the telescopic column 221. The telescopic measuring end of the linear displacement sensor 224 is fixedly connected to the second limiting block 223. When the second limiting block 223 is pushed up, the telescopic measuring end of the linear displacement sensor 224 retracts and measures the movement of the second limiting block 223. The measurement data is sent to the PLC control system in real time.

[0042] Furthermore, on the other side of the guide column 2, there is a rotating support column 3, a tie rod 31, a first hydraulic rod 32, and a second hydraulic rod 33. The guide column 2 and the rotating support column 3 are provided with a movable frame 4.

[0043] Specifically, the movable frame 4 has a welded blocking frame 41 at its tail end, and a rotatably connected support shaft 42 at its upper end. The support shaft 42 has a rotatably connected guide wheel 421, which rolls inside the cavity of the guide column 2.

[0044] One end of the rotating support column 3 is rotatably connected to the guide column 2, and the other end of the rotating support column 3 is provided with a first support wheel 34 rotatably connected. The first support wheel 34 is tangent to the lower end of the movable frame 4. One end of the pull rod 31 is rotatably connected to the rotating support column 3, and the other end of the pull rod 31 is rotatably connected to the support shaft 42. The tail end of the first hydraulic rod 32 is rotatably connected to the bottom movable bracket 1, and the telescopic end of the first hydraulic rod 32 is rotatably connected to the rotating support column 3. The tail end of the second hydraulic rod 33 is rotatably connected to the guide column 2, and the telescopic end of the second hydraulic rod 33 is rotatably connected to the rotating support column 3. The first hydraulic rod 32 and the second hydraulic rod 33 drive the rotating support column 3 to rotate, and the rotating support column 3 drives the first support wheel 34 to push the movable frame 4 to rotate. The pull rod 31 drives the movable frame 4 to change height along the guide column 2 when rotating.

[0045] Furthermore, a movable telescopic frame 5 and a fixedly connected support frame 43 are provided on one side of the movable frame 4. The support frame 43 is provided with a rotatingly connected second support wheel 431 in an array. The lower end of the telescopic frame 5 is tangent to the second support wheel 431. The second support wheel 431 provides bottom support for the movement of the telescopic frame 5.

[0046] The movable frame 4 is equipped with an array of drive shafts 44. On the other side of the movable frame 4, a first motor 45 is fixedly connected. The shaft of the first motor 45 is fixedly connected to a group of drive shafts 44 through a coupling. An array of synchronous sprockets 46 are fixedly installed on the drive shafts 44. The synchronous sprockets 46 are inside the movable frame 4. The synchronous sprockets 46 are rotated and connected by a synchronous chain 47, so that all drive shafts 44 can rotate synchronously clockwise or counterclockwise.

[0047] Each drive shaft 44 is also equipped with a fixedly connected drive wheel 48. The drive wheel 48 rotates inside the telescopic frame 5 and is tangent to the inner wall of the telescopic frame 5. When the drive shaft 44 rotates, it drives the drive wheel 48 to rotate synchronously, thereby driving the telescopic frame 5 to move and extend. When the telescopic frame 5 is retracted to the last position, the blocking frame 41 blocks the movement of the telescopic frame 5 to prevent the telescopic frame 5 from slipping when the moving frame 4 rotates and rises.

[0048] Furthermore, the support crossbeam 6 is installed between the two sets of telescopic frames 5. Both sides of the support crossbeam 6 are welded to the telescopic frames 5. When the telescopic frames 5 move and extend, they drive the support crossbeam 6 to move synchronously. The support crossbeam 6 is provided with an array of third support wheels 61 below it. The upper end face of the support crossbeam 6 is provided with a turntable bearing 62 and a second motor 63. The outer ring of the turntable bearing 62 is fixedly connected to the support crossbeam 6. The second motor 63 is connected to a right-angle reducer.

[0049] A rotatable parking frame 7 is provided above the support crossbeam 6. The lower end face of the parking frame 7 is fixedly connected to the inner ring of the turntable bearing 62. A rotating frame 73 is fixedly connected to the lower end of the parking frame 7. The right angle reducer shaft is fixedly connected to the center of the rotating frame 73. The second motor 63 drives the parking frame 7 to rotate by driving the rotating frame 73. An inclined guide plate 71 is provided at one end of the parking frame 7, and an inclined limit block 72 is provided at the other end of the parking frame 7.

[0050] Working principle:

[0051] When using it, please refer to Figure 11 As shown, when the parking equipment is idle, the positions of the telescopic frame 5, the support crossbeam 6, and the parking frame 7 inside the parking equipment are as follows: Figure 1 , Figure 2 As shown, the first hydraulic rod 32 and the second hydraulic rod 33 drive the movable frame 4 to descend to the lowest point. At this time, the movable frame 4 is horizontal with the ground, the third support wheel 61 is in contact with the ground, and the second motor 63 drives the parking frame 7 to keep parallel with the telescopic frame 5. The telescopic frame 5 moves back to the innermost end of the movable frame 4. When the vehicle needs to park, it can drive directly into the parking space and then drive onto the parking frame 7 through the guide plate 71. When the car limit block 72 blocks the car tire, it means that the car is parked in place. The driver can turn off the engine and get out of the car. When the car is retrieved, it can be driven away directly.

[0052] When a vehicle is parked in the parking rack 7, and a second car needs to enter the parking space, the first hydraulic rod 32 and the second hydraulic rod 33 push the rotating support column 3 to rotate and rise. When the rotating support column 3 rotates and rises, it pushes the movable frame 4 to rotate through the first support wheel 34. The pull rod 31 drives the movable frame 4 to change height along the guide column 2 during rotation, thereby raising the movable frame 4, the telescopic frame 5, the support crossbar 6, the parking rack 7, and the car to a certain height. Figure 3 In the schematic state, during the upward process, the guide wheel 421 rolls upward in the internal cavity of the guide column 2. When the guide wheel 421 contacts the second limit block 223, it pushes the second limit block 223 to continue to rise. At this time, the telescopic column 221 retracts, the telescopic measuring end of the linear displacement sensor 224 retracts and measures the movement of the second limit block 223. After the measurement value of the linear displacement sensor 224 reaches the set value, the PLC control system stops the parking equipment. At this time, the first electric cylinder 211 drives the first limit block 212 to move forward and insert into the guide column 2. The first limit block 212 blocks the lower end of the guide wheel 421 to limit the guide wheel 421 and prevent the moving frame 4 from descending when the parking equipment malfunctions. Then, the second car drives into the support crossbeam 6 and parking frame 7 and parks.

[0053] Once the first car is lifted, the second car can be driven away directly to retrieve it;

[0054] When the second car has not yet left, and the first car that has been raised needs to be driven away, the sprocket 14 rotates, driving the chain 15 to rotate. The chain 15 pulls the parking equipment along the slide rail 13 to the road inside the garage through the drive connecting block 12. Then, the first limit block 212 moves back to unlock the guide wheel 421. The first hydraulic rod 32 and the second hydraulic rod 33 drive the moving frame 4 and the car to the lowest point. After the moving frame 4 is level with the ground, the third support wheel 61 contacts the ground. The first motor 45 starts and drives the telescopic frame 5 forward through the drive wheel 48. The telescopic frame 5 pushes the support crossbar 6, the parking frame 7 and the car forward. The third support wheel 61 provides support. The telescopic frame 5 stops when it reaches its longest point. Since the width of the road inside the underground garage is limited, when the telescopic frame 5 is fully extended, the car cannot lower the parking frame 7. At this time, the second motor 63 starts and drives the parking frame 7 and the car to rotate 90°. Then the driver unlocks the car and drives away the first car.

[0055] If the second car has not yet left, and a new first car needs to be driven in, simply repeat the above steps in reverse.
