Description

Technical Field

[0001] This invention belongs to the field of construction, specifically relating to a novel multi-level parking system. Background Technology

[0002] With the development of the national economy, the increase in residents' income, and the decline in vehicle prices, the proportion of residents owning cars has been increasing rapidly in recent years. However, urban construction often lags behind, resulting in insufficient parking spaces in public and residential areas to meet the demand. The increasing demand has driven the technological upgrading of parking lots, leading to the emergence of many multi-level parking technologies, such as double-layer parking garages and rolling parking garages. In particular, rolling parking garages can provide more than ten parking spaces while occupying only three or four existing spaces. In areas with high parking demand, this type of parking garage has developed rapidly.

[0003] However, rolling parking systems still have shortcomings. Every time a vehicle lands, the entire rolling parking device needs to be rotated, which consumes a lot of energy. Although rolling parking systems occupy a small area, they still have certain requirements for land area. For some communities, it is difficult to build rolling parking systems in small, unused spaces.

[0004] How to construct a rotating parking system that can flexibly utilize land and upper space while reducing energy consumption during use is a pressing technical problem that needs to be solved. Summary of the Invention

Each gear unit includes at least two U-shaped fixing blocks, each U-shaped fixing block forming two slots with the outer surface of the circular mechanisms. The outer surface of the U-shaped fixing blocks has horizontally distributed straight teeth evenly distributed from bottom to top. Each vertical rack assembly... Each component includes multiple vertical racks distributed from bottom to top. Each vertical rack has horizontal straight teeth distributed from bottom to top. The vertical racks are fixed to a central column and have an I-shaped cross-section. Adjacent vertical racks in the vertical direction have rack gaps that allow the corresponding circular mechanism and its corresponding U-shaped fixing block to pass through. When the U-shaped fixing block is located in the corresponding rack gap, the U-shaped fixing block and the vertical rack at that position form a rack track.

Below the lower ring of the thrust bearing is a support ring for a lower ring of a support plate. The support ring has... The system includes a limiting ring for supporting the C-shaped slider. Both the limiting ring and the limiting ring have a gap at the rack track for the rack track and the vehicle lifting mechanism to pass through. The thrust bearing is located inside the limiting ring. The top of the limiting ring is close to the bottom of the U-shaped fixing block and has a gap with the bottom of the U-shaped fixing block. The top of the ring has a ring of driven teeth. The first drive unit includes a second power source fixed on the central column. The second power source is located above the ring. The output end of the second power source has a second drive gear that meshes with the driven teeth. The control system includes a controller, which is connected to the first power source and the second power source respectively.

[0006] Preferably, there are two vertical rack groups, and each rack unit includes two convex-shaped fixing blocks. The two convex-shaped fixing blocks of each rack unit are used to cooperate with two corresponding C-shaped sliders, and the distance between the two convex-shaped fixing blocks of each rack unit is equal to the distance between the two vertical rack groups.

[0007] Preferably, each upright arm is provided with two C-shaped sliders, one above the other, which correspond to and cooperate with two adjacent circular mechanisms at each parking space in the height direction.

[0008] Preferably, the upper C-shaped slider has ball bearings embedded on both inner sides in the horizontal direction and on the inner side of the back, and the lower C-shaped slider has ball bearings embedded on both inner sides in the horizontal direction and on the outer side of the back.

[0009] Preferably, the parking unit includes a base frame fixed to the cross arm, a middle transverse moving frame, and an upper longitudinal moving frame. The base frame is fixed to the two cross arms by four pressure sensors. The outer side of the base frame is provided with a side plate. Two transverse slide rails are provided on the base frame. The transverse moving frame slides with the transverse slide rails through a guide groove at the bottom and rollers in the groove. The side plate is provided with a first positioning push rod connected to the transverse moving frame. The upper surface of the transverse moving frame is provided with two longitudinal slide rails extending in the longitudinal direction. The longitudinal moving frame slides with the longitudinal slide rails through a guide groove at the bottom and rollers in the groove. The rear side of the transverse moving frame is provided with a rear plate. The rear plate is provided with a second positioning push rod connected to the tail of the longitudinal moving frame. The controller is connected to each of the pressure sensors, the first positioning push rod, and the second positioning push rod.

[0010] Preferably, the control system further includes a battery mounted on the parking unit.

[0011] Preferably, the mains power line is installed inside the center column, and the mains power line has a socket at the parking position on the center column. The socket has a conical guide hole. The parking unit is equipped with a third positioning push rod. The front end of the push rod has a spring, and the front end of the spring has a conical plug. The tail end of the plug is connected to the battery through a charger.

[0012] The present invention relates to a novel rotary multi-level parking system. When parking, the car is placed on the vehicle lifting mechanism. The control system then drives the lifting mechanism via a first drive gear from a first power source to rise along a vertical rack track to a set height. At this time, the first drive gear at the output end of the first power source meshes with the transverse straight teeth on the corresponding U-shaped fixing block, and the C-shaped slider slides and is locked onto the corresponding U-shaped fixing block. Then, the controller drives the driven gear of the first drive unit to rotate the ring to the parking position. The first power source drives the lifting mechanism to lower the C-shaped slider onto the limiting ring. At this time, the limiting ring and the corresponding U-shaped fixing block together limit and fix the C-shaped slider. The first power source can be turned off to save energy. The entire process only requires rotating a limited number of vehicles on the same level ring to achieve parking, and the energy consumption of same-level rotating parking is much lower than that of existing vertical rotating rolling parking devices. Retrieving the car is done by reversing the operation. This new type of rotating multi-level parking garage occupies very little ground space, with only the central column taking up floor area. It can be built in a corner, with vehicles parked in the air. Only one parking space is needed for parking and retrieval, and this location can even be set directly on the passageway outside the parking space. It allows for quick and easy parking with minimal impact on traffic flow. Only the central column requires a certain amount of space for long-term use. The vertical rack adjacent to the thrust bearing has an opening groove to avoid interference with the thrust bearing, ensuring the continuity of the transverse straight teeth on the rack track while preventing interference with the normal rotation of the thrust bearing.

[0013] Furthermore, there are two vertical rack assemblies, with two C-shaped sliders on each vertical arm, resulting in smoother operation.

[0014] Furthermore, the upper C-shaped slider mainly bears the outward pulling force, and its two inner sides and the inner side of the back are embedded with ball bearings, making the upper and lower rack tracks smoother. The lower C-shaped slider mainly bears the inward pressure, and its outer side of the back is embedded with ball bearings. In use, the ball bearings embedded on the outer side of the back press against the inner surface of the wing plate of the vertical rack and the outer surface of the ring. On the one hand, it provides support and prevents the outer surface of the C-shaped slider from pressing against the vertical rack and causing jamming under pressure. On the other hand, together with the ball bearings embedded on the two inner sides of the back, it further makes the upper and lower rack tracks smoother.

[0015] Furthermore, since different vehicles park in the parking lot each day, their center of gravity varies after parking. This can cause the vehicle lifting mechanism to bear a large torque, affecting operational stability during lifting and circumferential movement. For example, if the center of gravity is forward, the front L-shaped support arm experiences greater stress, causing the vehicle lifting mechanism to twist. This increases the torque and friction between the C-shaped slider, rack and pinion rail, and convex fixing block, potentially leading to wear, noise, or even jamming. Conversely, if the center of gravity is outward, the bending point of the L-shaped support arm experiences greater stress, making it prone to fatigue. Simultaneously, the lower C-shaped slider experiences increased pressure, leading to wear and potentially causing tipping. The parking unit's structure uses pressure sensors to detect pressure changes and adjusts the vehicle's center of gravity within a set area using first and second positioning push rods, significantly enhancing the stability and lifespan of the vehicle lifting mechanism.

[0016] Furthermore, the control system also includes batteries installed on the parking unit, which is more convenient for mobile structures to use as a power source.

[0017] Furthermore, the socket uses a tapered guide hole and a tapered plug for easy plugging and charging. The front end of the push rod has a spring, which reduces the requirement for insertion accuracy and makes the process smooth, preventing damage to the plug. Attached Figure Description

[0021] To clearly illustrate the beneficial effects of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. Specific embodiments are only used to explain the present invention and are not intended to limit the present invention. Example

[0022] A new type of rotating multi-level parking garage, such as Figure 1-7 As shown, the system includes a central column 1 buried in the ground, multiple ring mechanisms rotatably mounted on the central column from bottom to top, multiple gear units spaced apart along the circumference of the ring mechanisms, a vehicle lifting mechanism movably mounted on the gear units, at least one vertical rack group 17 vertically fixed to the side of the central column, a first drive unit for driving the ring mechanisms to rotate, and a control system. In this embodiment, the central column is a structure of an outer steel cylinder and an inner concrete ring. To increase the stability of the central column, a reinforced concrete expansion end is poured at the bottom of the central column below the ground. There are 10 ring mechanisms, divided into five groups. Each ring mechanism has three gear units, and there are two vertical rack groups 17, which extend vertically and are arranged in parallel.

[0023] The gear unit includes at least two U-shaped fixing blocks 3. In this embodiment, the gear unit includes two U-shaped fixing blocks. Each U-shaped fixing block forms two slots with the outer surface of the ring mechanism. The outer surface of the U-shaped fixing block has transverse straight teeth 7 evenly distributed from bottom to top. Each vertical rack group includes multiple vertical racks distributed from bottom to top. Each vertical rack has transverse straight teeth distributed from bottom to top. The vertical racks are welded and fixed to the central column and have an I-shaped cross-section. There is a rack gap between adjacent vertical racks in the vertical direction for the corresponding ring mechanism and the U-shaped fixing block to pass through, and the U-shaped fixing block is located in the corresponding rack gap. When the convex-shaped fixing block is in the middle, it forms a rack track with the vertical rack corresponding to the position. The vehicle lifting mechanism includes at least one L-shaped support arm. In this embodiment, there are two L-shaped support arms. The L-shaped support arm includes a vertical arm 9 and an integrally set horizontal arm 6. The vertical arm of the L-shaped support arm is connected by at least two first horizontal bars 12. A parking unit 5 is set on the horizontal arm of the L-shaped support arm. Each vertical arm has at least one C-shaped slider 8 that cooperates with the rack track guide. In this embodiment, each vertical arm has two upper and two lower C-shaped sliders 8. The two C-shaped sliders cooperate with the two adjacent circular mechanisms at each parking space in the height direction. The vertical length of the C-shaped slider is less than the vertical length of the convex-shaped fixing block 3. The outer surface of the C-shaped slider has a gear through-hole 27. A first power source 11 is fixed on the first crossbar 12. In this embodiment, the first power source is a motor, such as a geared motor. The output end of the first power source has a first drive gear 10. The teeth of the first drive gear pass through the gear through-hole 27 from the outside in and mesh with the transverse straight teeth on the rack track. To increase the stability of the first drive gear 10, the shaft of the first drive gear 10, away from the first power source, is fixed to the vertical arm by a bearing. Two convex-shaped fixing blocks in each gear unit are used to cooperate with two corresponding C-shaped sliders. The distance between the two convex-shaped fixing blocks in each gear unit is equal to the distance between the two vertical rack groups.The ring mechanism includes a steel ring 2 rotatably mounted on a central column and a thrust bearing located below the ring 2. The ring is fixed to the upper ring 16 of the thrust bearing. Below the lower ring 15 of the thrust bearing is a support ring 4, which is a steel ring with a reinforcing rib 13 at the bottom. The support ring has a limiting ring 14 for supporting and limiting the C-shaped slider 8. The limiting ring 14 is also a steel ring. Both the support ring and the limiting ring have a gap 18 at the rack and pinion track for the rack and pinion track and the vehicle lifting mechanism to pass through. The thrust bearing is located inside the limiting ring 14. The top of the limiting ring is close to the bottom of the convex-shaped fixing block and is aligned with the convex shape. The bottom of the fixed block has a gap to avoid interfering with the rotation of the convex fixed block. The vertical rack adjacent to the thrust bearing has an opening groove to avoid the thrust bearing. The top of the ring has a ring of driven teeth. The first drive unit includes a second power source 30 fixed on the central column. The second power source is a geared motor. The second power source is located above the ring. The output end of the second power source has a second drive gear that meshes with the driven teeth. In this embodiment, the second drive gear is a bevel gear, and the driven teeth are bevel teeth that mesh with the bevel gear. The control system includes a controller (not shown in the figure). The controller is connected to the first power source and the second power source respectively.

[0024] In this embodiment, the upper C-shaped slider has ball bearings 28 embedded on both inner sides of its horizontal axis and the inner side of its back, while the lower C-shaped slider has ball bearings 29 embedded on both inner sides of its horizontal axis and the outer side of its back. The upper C-shaped slider mainly bears the outward pulling force, and the ball bearings on its two inner sides of its horizontal axis and the inner side of its back make the upper and lower rack tracks smoother. The lower C-shaped slider mainly bears the inward pressure, and the ball bearings on its outer side of its back are used. During use, the ball bearings on the outer side of its back rest against the inner surface of the wing plate of the vertical rack and the outer surface of the ring. On the one hand, this provides support and prevents the outer surface of the C-shaped slider from pressing against the vertical rack under pressure, causing jamming. On the other hand, together with the ball bearings on the two inner sides of its horizontal axis, it further makes the upper and lower rack tracks smoother.

[0025] In this embodiment, the parking unit includes a base frame 20 fixed to the crossarms, a middle transverse moving frame 31, and an upper longitudinal moving frame 25. The base frame is fixed to the two crossarms by four pressure sensors 19, with two pressure sensors 19 spaced apart on each crossarm. In this embodiment, to prevent the base frame from detaching from the crossarms, bolts 32 are welded to the crossarms. Bolt holes are provided on the base frame, and the bolts pass through the base frame and are secured by nuts 33. Side plates 22 are provided on the outer side of the base frame, and two transverse slide rails 21 are provided on the base frame. The transverse moving frame 31 slides with the transverse slide rails through guide grooves at the bottom and rollers in the grooves. In conjunction with the above, the side plate has a first positioning push rod 23 connected to the transverse moving frame. The upper surface of the transverse moving frame has two longitudinal slide rails 24 extending in the longitudinal direction. The longitudinal moving frame 25 slides with the longitudinal slide rails through a guide groove at the bottom and rollers in the groove. The rear side of the transverse moving frame has a rear plate 26, on which a second positioning push rod (not shown in the figure) connected to the tail of the longitudinal moving frame is set. The controller is connected to each pressure sensor, the first positioning push rod, and the second positioning push rod. The control system also includes a battery (not shown in the figure) installed on the parking unit, specifically on the first crossbar. The mains power line is installed inside the center column, and a socket (not shown in the figure) is installed at the parking position on the center column. The socket has a tapered guide hole. The parking unit has a third positioning push rod (not shown in the figure), specifically on the first crossbar. The front end of the push rod has a spring, and the front end of the spring has a tapered plug. The tail end of the plug is connected to the battery through a charger.

[0026] In this embodiment of the rotary multi-level parking system, when parking, the car is placed on the vehicle lifting mechanism. Then, the control system drives the lifting mechanism to rise to a set height along the vertical rack track via the first drive gear of the first power source. At this time, the first drive gear at the output end of the first power source meshes with the transverse straight teeth on the corresponding convex fixed block, and the C-shaped slider slides and is locked on the corresponding convex fixed block. Then, the controller drives the driven tooth of the first drive unit to drive the ring to rotate to the parking position. The first power source drives the lifting mechanism to lower the C-shaped slider onto the limiting ring. At this time, the limiting ring and the corresponding convex fixed block together limit and fix the C-shaped slider. The first power source can be turned off to save energy. The entire process only requires rotating a limited number of vehicles on the same level ring to achieve parking, and the energy consumption of same-level rotating parking is much lower than that of the existing vertical rotating rolling parking device. When retrieving the car, the operation is reversed. This new type of rotating multi-level parking garage occupies very little ground space, with only the central column taking up floor area. It can be built in a corner, with vehicles parked in the air. Only one parking space is needed for parking and retrieval, and this location can even be set directly on the passageway outside the parking space. It allows for quick and easy parking with minimal impact on traffic flow. Only the central column requires a certain amount of space for long-term use. The vertical rack adjacent to the thrust bearing has an opening groove to avoid interference with the thrust bearing, ensuring the continuity of the transverse straight teeth on the rack track while preventing interference with the normal rotation of the thrust bearing.

[0027] In addition, there are two vertical rack assemblies, with two C-shaped sliders on each arm, resulting in smoother operation. Since different vehicles park in the parking lot each day, their center of gravity varies after parking, which can cause the vehicle lifting mechanism to bear a large torque. This affects operational stability during lifting and circumferential movement. For example, if the center of gravity is forward, the front L-shaped support arm experiences greater force, causing the vehicle lifting mechanism to twist. This increases the torque and friction between the C-shaped sliders, rack rails, and convex fixing blocks, potentially leading to wear, noise, or even jamming. Conversely, if the center of gravity is outward, the bending point of the L-shaped support arm experiences greater stress, leading to fatigue. Simultaneously, the lower C-shaped sliders experience increased pressure and are prone to wear, potentially posing a risk of tipping over. The parking unit's structure uses pressure sensors to detect pressure changes and adjusts the vehicle's center of gravity within a set area using first and second positioning push rods, significantly enhancing the stability and lifespan of the vehicle lifting mechanism. The control system also includes a battery installed on the parking unit; using batteries as a power source is convenient for a moving structure. The socket uses a tapered guide hole and a tapered plug for easy plugging and charging. The front end of the third positioning push rod has a spring. The flexibility of the spring reduces the requirement for insertion accuracy and makes the process smooth, preventing damage to the plug.

[0028] It should be noted that the electrical components of the vehicle lifting mechanism, such as pressure sensors, the first power source, and the first, second, and third positioning push rods, are all connected to the controller via Bluetooth, Wi-Fi, and / or GPRS communication. The controller can be divided into sub-controllers on the vehicle lifting mechanism and a central controller on the ground that communicates with each other.

[0029] In other embodiments, unlike the embodiments described above, a rack and pinion track can be provided, and an L-shaped support arm can also be provided. Although this structure can be used in theory, the rack and pinion track and the L-shaped support arm need to be set wider, and the stability is reduced.

[0030] In other embodiments, unlike the embodiments described above, such as Figure 8 As shown, a covered rain shield 34 can also be installed around the central pillar 1 to protect the vehicle from rain. A guard 35 can also be installed in the rain shield 34 at the parking position to prevent the vehicle from falling and causing greater damage. However, the rain shield 34 will occupy more space.

[0031] Specific parking instructions: Step 1: After the vehicle is parked on the longitudinal moving frame, the controller controls the first positioning push rod to push the lateral moving frame and the second positioning push rod to push the longitudinal moving frame, so that the center of gravity of the vehicle is positioned in the set position. The position is relatively simple to determine. For example, in the longitudinal direction, the pressure of the front and rear pressure sensors on the same side is equal. In the lateral direction, the pressure on the outer side is less than the pressure on the inner side. A ratio range of inner and outer pressure can be set according to the actual situation. When the first positioning push rod extends to its limit, even if the inner and outer pressures are not within the ratio range, it is assumed to meet the requirements. Step 1: Then the controller controls each first power source to start. Through the meshing motion of the gear and rack, the vehicle lifting mechanism is driven to rise along the vertical rack track to a certain parking height. Then the first drive unit drives the ring mechanism to rotate. The convex fixed block, along with the C-shaped slider, rotates the vehicle lifting mechanism around the central column to the parking position. The C-shaped slider falls slightly onto the limit ring 14. The convex fixed block and the limit ring 14 jointly position the vehicle lifting mechanism. Then the first power source is de-energized. Step 3: When the battery needs to be charged, the third positioning push rod extends, and the spring at the front end flexibly inserts the conical plug into the conical guide hole to charge the battery.

[0032] The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art to which this invention pertains may make any modifications, additions, or equivalent substitutions to the described embodiments without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
