Description

Technical Field

[0001] This utility model relates to the field of automated parking system technology, specifically to an automated parking system. Background Technology

[0002] With rapid economic development, parking difficulties have become a widespread social problem in economically developed cities. To address this issue, multi-level parking garage projects are increasingly common. However, in the renovation of some older communities, the initial planning not only resulted in a severe shortage of parking spaces, but also, due to the typical width of parking spaces being only 2-3 meters, the parking capacity of these older communities is severely limited. Expanding the number of parking spaces inevitably requires reducing the width of individual parking spaces, which significantly increases the cost of neighborhood negotiations during the renovation process. Therefore, the construction of multi-level parking garages is crucial in the renovation of older communities. Simultaneously, older communities face a common problem: very limited space for multi-level parking garage construction, especially in terms of the front-to-back span of parking spaces, which poses a significant obstacle to its construction. Furthermore, the high traffic density in older communities also necessitates improved parking efficiency. Clearly, established multi-level parking garage systems are insufficient to solve the parking lot renovation challenges of older communities.

[0003] Therefore, existing lift-and-slide automated parking systems are widely used due to their compact structure and stable operation. In lift-and-slide automated parking systems, the vehicle platform typically needs to move between the travel rail and the lift-and-slide platform, rotating on the platform to store and retrieve vehicles. However, the layout of the support columns on both sides of the travel rail in these systems often does not adequately consider the rotation radius of the vehicle platform. This could potentially lead to collisions between the platform and the support columns during rotation. To avoid collisions, sufficient safety distance must be provided for the platform's movement, which forces an increase in the distance between the support columns and the travel rail, thus increasing the overall size of the equipment and its floor space.

[0004] Furthermore, to meet the parking needs of different vehicles (such as sedans and SUVs), the length of the vehicle platform usually needs to be adjusted within a certain range. However, the structural design of traditional automated parking systems fails to optimize the relative positions between the supporting columns and the travel tracks, resulting in a waste of space when the size of the vehicle platform changes, as the overall size of the equipment still needs to be designed according to the maximum requirement.

[0005] Therefore, for lift-and-slide automated parking systems, ensuring that the rotation of the vehicle platform does not interfere with the supporting columns, while minimizing the size of each component in the equipment to meet the needs of vehicles of different sizes while occupying less space, is an urgent problem to be solved. Utility Model Content

[0006] In view of the above problems, this utility model provides a three-dimensional parking garage that not only has the advantages of a non-avoidance three-dimensional parking garage, but also improves the structural strength and load-bearing capacity of the upper track beam by configuring multiple H-beams and multiple reinforcing units in the upper track beam, thereby greatly avoiding local deformation of the track beam device and significantly improving the safety and stability of the vehicle platform during operation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a three-dimensional parking garage, comprising: a main frame including a front column and a rear column aligned with the front column, and a pair of supporting columns of the same height as the front and rear columns, with the pair of supporting columns located on both sides of the front and rear columns; a travel track connecting the front and rear columns; a lifting drive unit; and a lifting turntable capable of being driven by the lifting drive unit to move up and down along the front column, the lifting turntable including: a turntable base; and a connecting track installed on the turntable base, the track being 1.2-1.5 meters long, and capable of moving up and down around the turntable base with the vertical axis as its axis. The platform includes: a vehicle platform with a length of 3.5-5 meters and a width of 1.8-2.4 meters; a support frame located on one side of the vehicle platform and in the middle of the vehicle platform; and a walking device installed on the support frame, which is matched with the walking track and the connecting track respectively. The vertical distance L1 between the support column and the walking track is 2.5-3.2 meters, and the distance L2 between the vertical foot of the support column on the walking track and the front column is not less than 2.3-3 meters. When the value of L1 increases, the value of L2 decreases.

[0009] In some embodiments, each support column is provided with a rolling support unit facing the travel track, and the distance L3 between the vertical foot of the support column on the travel track and the rear column is not less than 0.9 meters.

[0010] In some embodiments, the distance between the front post and the rear post is 3.5-5 meters, and when the value of L1 increases, the value of L3 decreases.

[0011] In some embodiments, the traveling track includes an upper track beam and a lower track beam located below the upper track beam. The upper surface, lower surface, and inner surface of the upper track beam form a first track surface, a second track surface, and a third track surface, respectively, and the outer surface of the lower track beam forms a fourth track surface. The traveling device includes an upper traveling unit, a middle traveling unit, and a lower traveling unit respectively disposed at the upper end, middle part, and lower end of the upright. The upper traveling unit is capable of moving along the first track surface and the third track surface, the middle traveling unit is capable of moving along the second track surface, and the lower traveling unit is capable of moving along the fourth track surface.

[0012] In some embodiments, the vehicle platform further includes a connector disposed on the same side of the vehicle platform as the upright; the travel track further includes a travel drive unit disposed on the top of the lower track beam, the travel drive unit including: a transmission seat mounted on the front end of the lower track beam, having a transmission shaft extending through the transmission seat along an extension direction perpendicular to the travel track, and a first transmission wheel and a second transmission wheel disposed at both ends of the transmission shaft; a drive seat mounted on the rear upright, having two first drive members and a second drive member disposed side by side, the first drive shaft of the first drive member and the second drive shaft of the second drive member having opposite orientations, and the ends of the first drive shaft and the second drive shaft respectively being provided with a first drive wheel and a second drive wheel that match the first transmission wheel and the second transmission wheel; a transmission member, which respectively cooperates with the first drive wheel and the first transmission wheel, and the second drive wheel and the second transmission wheel; a socket disposed on the transmission member, under the drive of the first drive member and the second drive member, the transmission member can circulate back and forth between the first drive wheel and the first transmission wheel, and the second drive wheel and the second transmission wheel, and realize the cooperation between the socket and the connector.

[0013] In some embodiments, the connecting track includes an upper connecting beam and a lower connecting beam corresponding to the upper track beam and the lower track beam, respectively; the lifting turntable also includes a pair of stop units respectively disposed at both ends of the upper connecting beam, and a trigger unit disposed on the side of the turntable base. During the rotation of the upper connecting beam around the turntable base, the stop units respond to the abutment or separation of the trigger unit so that the upper connecting beam forms an upper track groove for limiting the upper traveling unit.

[0014] In some embodiments, the upper traveling unit includes an upper wheel seat and an upper traveling wheel assembly mounted on the upper wheel seat, and the lower traveling unit includes a lower wheel seat and a lower traveling wheel assembly mounted on the lower wheel seat, wherein the length of the upper wheel seat corresponds to the length of the upper connecting beam, and the length of the lower wheel seat corresponds to the length of the lower connecting beam.

[0015] In some embodiments, the ratio L4 between the length of the upper wheel seat and the length of the vehicle platform is 0.2-0.4. When the value of L4 decreases, the distance between the front pillar and the rear pillar increases.

[0016] In some embodiments, the upper connecting beam and the lower connecting beam are of equal length, and the length of the upper connecting beam extending beyond the turntable seat is less than the thickness of the front column.

[0017] In some embodiments, the upper connecting beam includes a horizontal track plate, a first vertical track plate disposed on the front side of the top of the horizontal track plate, and a second vertical track plate disposed on the front side of the bottom of the horizontal track plate. The first vertical track plate and the horizontal track plate enclose each other to form an upper track groove, and the second vertical track plate has a clearance hole. The stop unit includes a fixed plate connected to the bottom of the horizontal track plate and a rotating baffle rotatably connected to the fixed plate. The rotating baffle has a vertical section and an eccentric section connected to each other. The eccentric section corresponds to the clearance hole, and the mass of the eccentric section is greater than the mass of the vertical section, so that the rotating baffle has a tendency to rotate toward the turntable. The two ends of the horizontal track plate are provided with stop grooves adapted to the vertical section. Under the action of gravity, the vertical section contacts the inner wall of the stop groove, so that the center line of the vertical section is parallel to the center line of the turntable.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows:

[0019] The technical solution provided by this utility model constructs a three-dimensional parking garage with a reasonable structure and high space utilization. Through the cooperation of various components, it achieves smooth transfer and lifting of vehicles within the garage. The front and rear columns of the main frame, along with the supporting columns on both sides, form a stable foundation structure, providing reliable support for the entire garage system and ensuring the stability and safety of the vehicle platform during movement and lifting. The design of the connecting rails and the travel rails allows the vehicle platform to smoothly switch between different rails, thus achieving an organic combination of horizontal movement and vertical lifting of vehicles. Furthermore, by precisely controlling the vertical distance between the supporting columns and the travel rails, as well as the distance between their vertical feet and the front column, it is ensured that the vehicle platform will not interfere with the supporting columns during rotation. This allows the system to meet the parking needs of vehicles of different sizes while minimizing the overall size of each component, optimizing the space occupied by the equipment, and ensuring the efficient and smooth operation of the entire system.

Detailed Implementation

[0048] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0049] Reference Figures 1-6As shown, this utility model embodiment provides a three-dimensional parking garage, including a main frame 100, a travel track 200, a lifting drive unit 300, a lifting turntable 400, and a vehicle carrying platform 500. The main frame 100 includes a front column 110 and a rear column 120 aligned with the front column 110, and a pair of support columns 130 of the same height as the front column 110 and the rear column 120. A first limiting block 140 is provided on one side of the front column 110, and the pair of support columns 130 are located on both sides of the front column 110 and the rear column 120. The travel track 200 connects the front column 110 and the rear column 120. The lifting turntable 400 can be driven by the lifting drive unit 300 to rise and fall along the front column 110, and the lifting turntable 400 further includes a rotating... The platform 410 and the connecting rail 420 installed on the turntable 410, as well as the positioning stop assembly 430, are provided. The length of the connecting rail 420 is 1.2-1.5 meters, and the connecting rail 420 can be connected to the traveling rail 200 during the rotation of the turntable 410 with the vertical axis as the axis. The positioning stop assembly 430 has a positioning stop seat 431 and a first telescopic unit 432. When the first telescopic unit 432 is in the extended state, it partially extends out of the positioning stop seat 431 and can cooperate with the first limit block 140 to prevent the turntable 410 from descending.

[0050] Furthermore, the vehicle platform 500 can move linearly along the travel track 200. The vehicle platform 500 includes a vehicle platform 510 with a length of 3.5-5 meters and a width of 1.6-2.4 meters, a support frame 520 disposed on one side of the vehicle platform 510 and located in the middle of the vehicle platform 510, and a traveling device 530 disposed on the support frame 520. The traveling device 530 is matched with the travel track 200 and the connecting track 420 respectively. In addition, the vertical distance L1 between the support column 130 and the travel track 200 is 2.5-3.2 meters, and the distance L2 between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 is not less than 2.3-3 meters. When the value of L1 increases, the value of L2 decreases.

[0051] In the context of increasingly scarce urban space in modern cities, multi-level parking garages have become a key facility for solving parking problems due to their efficient use of space. The multi-level parking garage solution disclosed in this embodiment, with its unique design concept and technological innovation, not only improves the operational efficiency of parking garages and solves the problem of limited space in the renovation of old communities, but also demonstrates significant advantages in terms of economy and environmental adaptability.

[0052] The main frame 100 serves as the supporting and fixed structure of the automated parking garage. The front column 110 provides a vertical track for the lifting turntable 400 to ensure the stability of the vehicle platform 500 during lifting and avoid horizontal deviation. The rear column 120 and the front column 110 are connected to the travel track 200, ensuring the straightness of the travel track 200 and preventing track deformation when the vehicle platform 510 moves. The front column 110, rear column 120 and support column 130 form a stable triangular support structure, which can resist torsional loads caused by the rotation of the vehicle platform 510 or the off-center loading of the vehicle to a certain extent, and prevent the main frame 100 from deforming.

[0053] The structure of the vehicle platform 500 is crucial for ensuring the safe and efficient storage and retrieval of vehicles. The vehicle platform 510, the main component of the platform 500, is used to support the vehicle. It is typically designed to be robust enough to withstand the weight of the vehicle, and its surface may be covered with anti-slip material to ensure vehicle stability during movement. The support frame 520 is a vertical structure located on the side of the vehicle platform, its lower end connected to the side of the vehicle platform 510, and a traveling device 530 is mounted on it. The support frame 520 not only provides support for the traveling device 530 but may also serve a guiding and securing function in some designs.

[0054] Furthermore, the precise stopping of the lifting turntable 400 at a designated position on the front column 110, achieved through the cooperation between the first limiting block 140 on the front column 110 and the first telescopic unit 432 on the lifting turntable 400, ensures accurate docking between the connecting rail 420 and the traveling rail 200 within the lifting turntable 400. This allows vehicles to be precisely parked on the vehicle carrier 510, improving the stability and accuracy of equipment operation. Moreover, the coordinated action of the first telescopic unit 432 and the first limiting block 140 effectively prevents the lifting turntable 400 from descending unexpectedly. Even in the event of a malfunction in the lifting drive unit 300, the stability of the lifting turntable 400 can be maintained, enhancing the safety of the automated parking system and reducing the risk of vehicle damage due to control system failure.

[0055] It should be noted that, in order to ensure the precise docking between the connecting track 420 and the traveling track 200, in addition to adjusting the speed and working time of the lifting drive unit 300 through the relevant control system, the docking accuracy between the two can also be improved by limiting the size. For example, if the height of the walking track 200 above the ground is 2.2 meters, the height of the front column 110 is 6.7 meters, the overall height of the lifting turntable 400 is 1.9 meters, and the distance between the positioning stop assembly 430 and the top of the lifting turntable 400 is 0.3 meters, then the height of the first limiting block 140 above the ground can be set to 3.8 meters. That is, when the connecting track 420 in the lifting turntable 400 moves to a position that matches the walking track 200, the distance between the positioning stop assembly 430 and the bottom of the lifting turntable 400 is 1.6 meters. Since the height of the walking track 200 above the ground is 2.2 meters, the height of the first limiting block 140 above the ground can be reasonably set according to the above dimensions, i.e., 2.2 meters + 1.6 meters = 3.8 meters, to ensure the docking accuracy between the connecting track 420 and the walking track 200. In other words, the position of the first limiting block 140 on the front column 110 depends on the position of the travel track 200 on the front column 110 and the position of the positioning stop assembly 430 on the lifting turntable 400.

[0056] It should also be noted that when the vehicle platform 510 is transferred from the traveling rail 200 to the connecting rail 420, the vehicle platform 510 can rotate along with the connecting rail 420 under the drive of the lifting turntable 400. At this time, since the upright 520 is located in the middle of the vehicle platform 510, when the traveling device 530 on the upright 520 moves to the connecting rail 420, the vehicle platform 510 can rotate around the center of the upright 520 as the axis of rotation, and the axis of rotation of the vehicle platform 510 is basically equivalent to the axis of rotation of the lifting turntable 400. The rotation radius of the vehicle platform 510 mainly depends on its length and width. In order to avoid interference between the vehicle platform 510 and the supporting column 130 during rotation, it is necessary to ensure that the maximum rotation radius of the vehicle platform 510 is less than the distance between the supporting column 130 and the axis of rotation of the lifting turntable 400. The maximum rotation radius of the vehicle platform 510 is the distance between the center of the upright 520 and the diagonal of the vehicle platform 510. For example, if the length of the vehicle platform 510 is 3.8 meters and the width is 2.1 meters, its The minimum distance between the support column 130 and the rotation axis of the lifting turntable 400 is 2.8 meters. Correspondingly, when the length of the vehicle platform 510 is between 3.5 and 5 meters and the width of the vehicle platform 510 is between 1.8 and 2.4 meters, the maximum rotation radius of the vehicle platform 510 is between 2.5 and 3.5 meters. In this case, by limiting the vertical distance between the support column 130 and the travel track 200 to between 2.5 and 3.2 meters, not only can the vehicle platform 510 move smoothly between the travel track 200 and the support column 130, but the interference of the support column 130 with the wide side of the vehicle platform 510 during rotation can also be avoided. On the other hand, by limiting the distance between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 to not less than 2.3 to 3 meters, the interference of the support column 130 with the long side of the vehicle platform 510 during rotation can also be avoided.

[0057] It is understandable that the distance between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 can be determined not only based on the length and width of the vehicle platform 510, but also, under ideal conditions, calculated based on the dimensional relationships between the components. The so-called ideal conditions include: (1) not considering the joint gap between the connecting track 420 and the travel track 200; (2) after the vehicle platform 510 is transferred to the connecting track 420, the center of the vehicle platform 510, the center of the support frame 520, the center of the travel device 530, and the center of the connecting track 420 are the same center; (3) not considering the gap between the vehicle platform 510 and the travel track 200; (4) the calculation result uses an approximation and only retains one decimal place; (5) the length of the connecting track 420 is approximately equal to the length of the support frame 520; (6) not considering the assembly tolerances between other components in the automated parking system.

[0058] Specifically, refer to Figure 7 As shown, the distance between the vertical foot of the support column 130 on the travel track 200 and the front column 110 is approximately half the difference between the length of the vehicle platform 510 and the length of the connecting track 420. For example, when the length of the vehicle platform 510 is 5 meters and the length of the connecting track 420 is 1.2 meters, the distance between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 is 1.9 meters; when the length of the vehicle platform 510 is 5 meters and the length of the connecting track 420 is 1.5 meters, the distance between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 is 1.75 meters; when the length of the vehicle platform 510 is 3.5 meters and the length of the connecting track 420 is 1.5 meters, the distance between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 is 1 meter; when the length of the vehicle platform 510 is 3.5 meters and the length of the connecting track 420 is 1.2 meters, the distance between the perpendicular foot of the support column 130 on the travel track 200 and the front column 110 is 1.15 meters.

[0059] It can be observed that under the above ideal conditions, if the dimensions of the vehicle platform 510 and the connecting track 420 are both taken to their extreme values, the minimum distance L2 between the perpendicular foot of the supporting column 130 on the traveling track 200 and the front column 110 can be 1 meter. However, in actual application, the equipment is unlikely to be in a completely ideal state. Therefore, this application, by reasonably considering the existence of errors, gaps, and other dimensions, preferably configures L2 to be no less than 2.3-3 meters. This ensures that the vehicle platform 510 does not interfere with the supporting column 130 during rotation, while also giving the main frame 100 of the automated parking system, composed of the supporting column 130, the front column 110, and the rear column 120, better support performance and stability.

[0060] The technical solution provided by this utility model first constructs a three-dimensional parking garage with a reasonable structure and high space utilization. Through the cooperation of various components, the smooth transfer and lifting of vehicles within the garage are realized. Among them, the front column 110, rear column 120, and side support columns 130 of the main frame 100 form a stable foundation structure, providing reliable support for the entire parking garage system and ensuring the stability and safety of the vehicle platform 500 during movement and lifting. The design of the connecting track 420 and the walking track 200 allows the vehicle platform 500 to smoothly switch between different tracks, thereby realizing the organic combination of horizontal movement and vertical lifting of vehicles.

[0061] Secondly, by setting the positioning stop component 430 and the first telescopic unit 432, precise positioning can be achieved when the lifting turntable 400 reaches the designated position (i.e., the docking position of the connecting rail 420 and the traveling rail 200), ensuring that the vehicle can be accurately parked on the parking space (car carrier 510), thus improving the utilization efficiency of the garage. The cooperation between the first telescopic unit 432 and the limit block can effectively prevent the lifting turntable 400 from falling unexpectedly. Even if the lifting drive unit 300 fails, the stability of the lifting turntable 400 can be guaranteed, thereby improving the safety of the garage. Through the coordinated work of the precise positioning stop component 430 and the telescopic unit, high-precision control of the lifting turntable 400 can be achieved, which not only improves the operating efficiency of the garage but also reduces the risk of vehicle damage caused by inaccurate control, fully demonstrating the reliability and superiority of mechanical structures in automated equipment such as three-dimensional parking garages that have high requirements for safety and reliability.

[0062] Furthermore, by precisely controlling the vertical distance between the support column 130 and the travel track 200, and the distance between its perpendicular foot and the front column 110, specifically setting the vertical distance L1 between the support column 130 and the travel track 200 to between 2.5 and 3.2 meters, the overall lateral span of the automated parking system is limited to a very extreme range. No existing automated parking systems have a single garage width support distance less than 2.9 meters or even less than 2.8 meters. Reducing this lateral span not only ensures that the vehicle platform 510 will not interfere with the support column 130 during rotation, but also minimizes the overall size of each component while meeting the parking needs of vehicles of different sizes. This optimizes the space occupied by the equipment and ensures the efficient, smooth, and safe operation of the entire system.

[0063] In some embodiments, refer to Figure 2 , Figure 8 As shown, each support column 130 is provided with a rolling support unit 150 facing the travel track 200, and the distance L3 between the vertical foot of the support column 130 on the travel track 200 and the rear column 120 is not less than 0.9 meters.

[0064] It is important to note that if the vehicle platform 500 relies solely on the running track 200 for support, its mechanical model is a cantilever beam structure. When the vehicle is unevenly loaded, an overturning moment will occur, leading to stress concentration at the root of the track beam. In this application, the rolling support unit transforms the supporting column into a third support point, forming a triangular stable support structure with the running track, thereby improving the support stability for the vehicle platform. Furthermore, the running track 200 can restrict the vertical and longitudinal displacement of the vehicle platform 500, while the rolling support unit 150 can restrict the lateral displacement and rotational degrees of freedom of the vehicle platform 500, thus forming a complete six-degree-of-freedom constraint in space, greatly reducing the possibility of the vehicle platform 500 derailing. Moreover, if the running track 200 deforms unexpectedly, the rolling support unit 150 can still provide temporary support, buying time for emergency braking of the vehicle platform 500.

[0065] To further improve the support effect of the rolling support unit 150 on the vehicle platform 510, the size of L3 is configured to ensure the stability and reliability of the vehicle platform 510 when parked. Especially when the vehicle platform 510 is parked close to the rear column 120, if L3 is less than 0.9 meters (e.g., when L3 = 0, the supporting column 130 is flush with the rear column 120), the rolling support unit 150 and the traveling track 200 form a right-angled triangular support structure. This type of support undoubtedly has poorer stability compared to the non-right-angled triangular support structure formed when L3 is not less than 0.9 meters. This arrangement ensures that the supporting force of the rolling support unit 150 acts on the critical stress area of ​​the vehicle platform 510, which helps reduce localized wear on the track.

[0066] In some embodiments, continue to refer to Figure 1 As shown, the distance between the front post 110 and the rear post 120 is 3.5-5 meters, and when the value of L1 increases, the value of L3 decreases.

[0067] The spacing between the front upright 110 and the rear upright 120 corresponds to the length of the vehicle platform 510, ensuring the stability of the vehicle platform 510 during linear movement on the travel track 200. When the length of the vehicle platform 510 is fixed, L2 is typically greater than L3. This dimensional configuration allows the support upright 130 to be positioned closer to the rear upright 120, forming an asymmetrical "longer front, shorter rear" layout. This ensures that when the vehicle platform 510 rotates, its rear sweeping area completely avoids the support upright 130. Furthermore, most of the weight of the lifting turntable 400 and the vehicle platform 510 is borne by the front column 110. This configuration brings the support column 130 closer to the rear column 120, forming a "front-heavy, rear-light" load distribution, which meets the force requirements of the lifting drive unit 300 (installed on the front column 110). It also ensures that when the vehicle platform 510 is suspended, its center of gravity is always located between the front column 110 and the support column 130, reducing the risk of the vehicle platform 510 tipping over.

[0068] When the value of L1 increases, it means that the support column 130 moves outward, expanding the lateral movement space of the vehicle platform 500. At this time, the value of L3 decreases accordingly, shortening the distance between the support column 130 and the rear column 120, which can strengthen the support effect of the end of the travel track 200 on the vehicle platform 510.

[0069] Optionally, the ratio between L2 and L3 can be 3:1. For example, when the distance between the front column 110 and the rear column 120 is 4 meters, calculated at a 3:1 ratio, the distance from the vertical foot to the front column 110 is 3 meters, and the distance from the vertical foot to the rear column 120 is 1 meter. At this time, if the length of the vehicle platform 510 is 4 meters and the width is 3 meters, its maximum rotation radius around the rotation axis of the lifting turntable 400 is approximately 3.6 meters. Since the distance from the vertical foot of the supporting column 130 to the front column 110 is 3 meters, the vertical distance between the supporting column 130 and the traveling rail 200 is 3 meters. The straight-line distance between the supporting column 130 and the center of the lifting turntable 400 also depends on the length of the connecting rail 420. Assuming the length of the connecting rail 420 is 1.5 meters, the straight-line distance from the vertical foot of the supporting column 130 to the center of the lifting turntable 400 is approximately 3 + 1.5 / 2 = 3.75 meters. The straight-line distance between the supporting column 130 and the center of the lifting turntable 400 is... Meters. It can be seen that since 4.8 meters is greater than the maximum rotation radius of the vehicle platform 510 of 3.6 meters, the supporting column 130 will not interfere with the rotation process of the vehicle platform 510.

[0070] In some embodiments, refer to Figure 4 , Figure 6 and Figure 9 As shown, a second limiting block 160 is provided on the other side of the front column 110. The positioning block assembly 430 is located between the first limiting block 140 and the second limiting block 160. The positioning block assembly 430 also includes a second telescopic unit 433. When the second telescopic unit 433 is in the extended state, the extended part can cooperate with the second limiting block 160 to prevent the lifting turntable 400 from descending.

[0071] By adding a second limiting block 160 and a second telescopic unit 433, the positioning accuracy and stability of the automated parking garage lifting turntable 400 are further enhanced. Furthermore, the first limiting block 140 and the second limiting block 160, located on both sides of the supporting column 130, can achieve dual-sided limiting of the lifting turntable 400. Setting limiting devices on both sides of the lifting turntable 400 can balance the external forces that the lifting turntable 400 may experience during lifting, avoiding imbalance problems caused by excessive force on one side.

[0072] The cooperation between the second telescopic unit 433 and the second limiting block 160 provides additional safety assurance. Even if the limiting device on one side fails, the limiting device on the other side can still prevent the lifting turntable 400 from descending unexpectedly, thus improving the safety of the lifting turntable 400. In addition, the dual limiting block design allows the connecting rail 420 to maintain precise positioning of the lifting turntable 400 even when there is a slight deviation in rotational docking with the traveling rail 200, through the flexible adjustment of the first telescopic unit 432 or the second telescopic unit 433.

[0073] Preferably, the first telescopic unit 432 and the second telescopic unit 433 extend and retract synchronously.

[0074] Setting identical limit mechanisms on both sides simplifies the design of the control system. It eliminates the need for complex algorithms to adjust the extension and retraction speeds and timings on both sides, reducing control complexity and the number and complexity of control components, thus lowering maintenance costs. The limit devices on both sides of the lifting turntable 400 need to be precisely synchronized to ensure consistent vertical movement. Synchronized extension and retraction maintain the horizontal state of the lifting turntable 400 and balance the forces acting on it, ensuring smooth vehicle parking. Synchronized extension and retraction of the telescopic unit provides more reliable safety. In emergencies, the limit devices on both sides can function simultaneously to prevent accidental descent of the lifting turntable 400, improving its safety.

[0075] Furthermore, referring to Figure 9 and Figure 10As shown, the positioning stop assembly 430 also includes a drive motor 434, a transmission shaft 435 connected to the output shaft of the drive motor 434, a transmission gear 436 mounted on the transmission shaft 435, a transmission bearing seat 437 supporting the transmission shaft 435, a driven shaft 438, a driven gear 439 mounted on the driven shaft 438 and meshing with the transmission gear 436, and a driven bearing seat 440 for supporting the driven shaft 438. Among them, one of the first telescopic unit 432 and the second telescopic unit 433 is mounted on the transmission shaft 435, and the other is mounted on the driven shaft 438.

[0076] The mechanical transmission devices, including drive shaft 435, drive gear 436, driven shaft 438, and driven gear 439, effectively transmit the power of drive motor 434 to the two telescopic units, achieving efficient and reliable power transmission and ensuring the synchronous extension and retraction of the first telescopic unit 432 and the second telescopic unit 433. The support of drive bearing housing 437 and driven bearing housing 440 ensures the stable operation of drive shaft 435 and driven shaft 438, improving the stability and lifespan of the system. The mechanical transmission method simplifies the design of the electrical control system, reduces reliance on complex sensors and control algorithms, and lowers the complexity and maintenance costs of the system.

[0077] Furthermore, referring to Figure 11 As shown, a support block 441 is provided inside the positioning stop 431. The first telescopic unit 432 and the second telescopic unit 433 are both cams, and the cams have a first protrusion and a second protrusion. When the cam rotates to the first position, the first protrusion extends out of the positioning stop 431, and the pressing surface of the first protrusion can press against the bearing surface of the first limiting block 140. When the cam rotates to the second position, the first protrusion retracts into the positioning stop 431. In addition, when the cam rotates to the first position, the second protrusion can contact the support block 441 and stop the rotation trend of the cam.

[0078] The first protrusion of the cam, when pressed tightly against the bearing surface of the limiting block, allows the lifting turntable 400 to stop precisely at a specific position, ensuring that vehicles can be accurately parked in designated parking spaces. The rotation position of the cam controls the extension and retraction of the first protrusion. This mechanical control method simplifies the requirements of the electrical control system, reducing system complexity and failure rate. When the cam rotates to the first position, the first protrusion and the limiting block are tightly engaged, forming a stable support point, preventing the lifting turntable 400 from unexpectedly descending due to external forces or system malfunctions, thus improving the stability and safety of the lifting turntable 400. Furthermore, by adjusting the cam's design parameters, such as the height and shape of the protrusion, it can adapt to different positioning requirements and load conditions, increasing the system's flexibility and adjustability.

[0079] Furthermore, by engaging the first protrusion of the cam with the limiting block and contacting the second protrusion with the support block 441, dual positioning of the lifting turntable 400 at specific positions can be achieved. When the cam rotates to the first position, the second protrusion contacts the support block 441, forming an additional stopping force to prevent the cam from continuing to rotate due to external forces or system malfunctions, thereby avoiding accidental movement of the lifting turntable 400 and improving its stability and safety. The engagement of the support block 441 with the second protrusion simplifies the control system of the lifting turntable 400, reduces reliance on external power sources or sensors, and lowers system complexity and maintenance costs. Clearly, the mechanical cam-support block 441 engagement method has high durability and anti-interference capabilities, enabling stable operation in harsh environments and improving the overall system reliability.

[0080] In some embodiments, refer to Figure 12 and Figure 13 As shown, the traveling track 200 includes an upper track beam 210 and a lower track beam 220 located below the upper track beam 210. The upper surface, lower surface, and inner surface of the upper track beam 210 form a first track surface, a second track surface, and a third track surface, respectively, and the outer surface of the lower track beam 220 forms a fourth track surface. Furthermore, the traveling device 530 includes an upper traveling unit 531, a middle traveling unit 532, and a lower traveling unit 533, respectively disposed at the upper, middle, and lower ends of the upright frame 520. The upper traveling unit 531 can move along the first and third track surfaces, the middle traveling unit 532 can move along the second track surface, and the lower traveling unit 533 can move along the fourth track surface.

[0081] In this application, each walking unit in the walking device 530 can be a walking wheel, a walking slider, etc., and the specific structure of each walking unit is not limited. In addition, through the constraints of the upper first track surface and the third track surface on the upper walking unit 531, the constraint of the second track surface on the middle walking unit 532, and the constraint of the fourth track surface on the lower walking unit 533, a three-dimensional stable support structure of "three-point support and four-sided constraint" is formed between the walking track 200 and the walking device 530.

[0082] The upper traveling unit 531 and the middle traveling unit 532 jointly lock the upper track beam 210, which can resist the outward tilting moment of the vehicle platform 510; the lower traveling unit 533 can provide basic support and prevent the vehicle platform 510 from tilting inward, thereby completely solving the overturning risk of the single-sided cantilever structure.

[0083] In addition, the first and second track surfaces can constrain the vertical displacement of the car platform 510, the third track surface can constrain the lateral displacement of the car platform 510, and the fourth track surface can constrain the longitudinal displacement and pitch tendency of the car platform 510. Through the cooperation between the wheel and the rail, a rigid constraint is formed on the car platform 510 in multiple directions and at multiple contact points, which greatly suppresses the possible swaying of the car platform 510 along the X / Y / Z axes and the torsion around the Z axis during movement. This allows the load on the car platform 510 to be more reasonably distributed to multiple track surfaces and wheel sets, avoiding overload of a single point or a few wheel sets. This significantly reduces the contact stress between the wheel and the rail, greatly reduces abnormal wear and "rail biting" phenomenon, and thus greatly extends the life of the system and reduces the maintenance frequency and cost of the equipment.

[0084] In some embodiments, refer to Figure 14 and Figure 15 As shown, the vehicle platform 500 also includes a connector 540 disposed on the same side of the vehicle plate 510 as the upright 520; the travel track 200 also includes a travel drive unit 230 disposed on the top of the lower track beam 220. The travel drive unit 230 includes a transmission seat 231 installed at the front end of the lower track beam 220, a drive seat 232 installed on the rear column 120, a transmission component 233, and a socket 234 disposed on the transmission component 233.

[0085] The transmission base 231 has a transmission shaft 435 (not marked in the figure) extending through the transmission base 231 along a direction perpendicular to the travel track 200, and a first transmission wheel (not marked in the figure) and a second transmission wheel (not marked in the figure) disposed at both ends of the transmission shaft 435; the drive base 232 has two first drive members (not marked in the figure) and second drive members (not marked in the figure) arranged side by side, the first drive shaft of the first drive member and the second drive shaft of the second drive member are oriented in opposite directions, and the ends of the first drive shaft and the second drive shaft are respectively provided with a first drive wheel (not marked in the figure) and a second drive wheel (not marked in the figure) that match the first transmission wheel and the second transmission wheel; the transmission member 233 cooperates with the first drive wheel and the first transmission wheel, and the second drive wheel and the second transmission wheel respectively; under the drive of the first drive member and the second drive member, the transmission member 233 can circulate back and forth between the first drive wheel and the first transmission wheel, and the second drive wheel and the second transmission wheel, and realize the cooperation between the socket 234 and the plug 540.

[0086] Through the reciprocating motion of the transmission component 233 (such as a chain), the first and second driving components, which are arranged in opposite directions, can drive the vehicle platform 510 to move quickly in both directions, shortening the vehicle storage and retrieval time. The cooperative design of the connector 540 and the socket 234 allows the vehicle platform 510 to automatically disengage from the drive unit when transferred to the connecting rail 420, thereby realizing the rapid transfer of the vehicle platform 510 between the travel rail 200 and the connecting rail 420. The drive seat 232 is installed on the rear column 120, and the transmission seat 231 is located at the front end of the lower rail beam 220, which can disperse the power source position, facilitate maintenance, and reduce single-point load.

[0087] In some embodiments, refer to Figure 16 As shown, the connecting track 420 includes an upper connecting beam 421 and a lower connecting beam 422 corresponding to the upper track beam 210 and the lower track beam 220, respectively; the lifting turntable 400 also includes a pair of stop units 450 respectively disposed at both ends of the upper connecting beam 421, and a trigger unit 460 disposed on the side of the turntable base 410. During the rotation of the upper connecting beam 421 around the turntable base 410, the stop unit 450 responds to the pushing or separating of the trigger unit 460 so that the upper connecting beam 421 forms an upper track groove for limiting the upper traveling unit 531.

[0088] Through the cooperation between the stop unit 450 and the trigger unit 460, the stop unit 450 can effectively control the size of the openings at both ends of the upper track groove under the action of the trigger unit 460. When the vehicle platform 500 enters the upper track groove of the lifting turntable 400, the opening of the upper track groove is enlarged to allow the vehicle platform 500 to enter smoothly. After entering, the opening is narrowed to reliably limit the vehicle platform 500, effectively preventing the vehicle platform 500 from deviating or sliding during lifting or transfer, thereby improving the safety of the automated parking system.

[0089] Specifically, the vehicle platform 500 moves relative to the travel track 200 and the connecting track 420 through multiple traveling units mounted on it. When the upper traveling unit 531 moves in the upper track groove, it is only necessary to control the stop unit 450 to partially block the opening at the end of the upper track groove, making the size of the blocked opening smaller than the width of the upper traveling unit 531. This limits the upper traveling unit 531, thereby limiting the vehicle platform 500. Correspondingly, when the vehicle platform 500 moves from the upper track groove to the travel track 200, the trigger unit 460 triggers the stop unit 450 to rotate, which expands the size of the opening at the end of the upper track groove, making it larger than the width of the upper traveling unit 531, thereby enabling the upper traveling unit 531 to transfer between the connecting track 420 and the travel track 200.

[0090] In some embodiments, refer to Figure 14 and Figure 17As shown, the upper traveling unit 531 includes an upper wheel seat 5311 and an upper traveling wheel assembly 5312 mounted on the upper wheel seat 5311, and the lower traveling unit 533 includes a lower wheel seat 5331 and a lower traveling wheel assembly 5312 mounted on the lower wheel seat 5331. The length of the upper wheel seat 5311 corresponds to the length of the upper connecting beam 421, and the length of the lower wheel seat 5331 corresponds to the length of the lower connecting beam 422.

[0091] The lengths of the upper wheel seat 5311 and the lower wheel seat 5331 correspond to the lengths of the upper connecting beam 421 and the lower connecting beam 422, respectively. This ensures that the upper traveling unit 531 and the lower traveling unit 533 can be fully embedded in the connecting track 420, thereby enabling the smooth movement of the vehicle platform 510.

[0092] Optionally, the upper traveling wheel assembly 5312 can be composed of several first vertical wheels and several first horizontal wheels arranged in an alternating manner. The upper wheel seat 5311 has multiple notches corresponding to the first horizontal wheels. The arrangement of the first vertical wheels and first horizontal wheels allows the upper traveling unit 531 to contact both the first and third track surfaces simultaneously, thereby ensuring the stable movement of the vehicle platform 510 on the upper track beam 210 and preventing the vehicle platform 510 from derailing or shifting. Furthermore, the alternating arrangement of the first horizontal wheels and first vertical wheels enables the upper traveling wheel assembly 5312 to simultaneously exert pressure and side clamping functions on the upper track beam 210 within a limited space, while the notches ensure effective contact between the first horizontal wheels and the inner wall of the upper track beam 210.

[0093] The middle traveling unit 532 includes a middle traveling wheel set 5321 composed of several second vertical wheels, and a lower traveling wheel set 5312 has several second horizontal wheels. The second vertical wheels can contact the second track surface, and the second horizontal wheels can contact the fourth track surface. The arrangement of the second vertical wheels and the second horizontal wheels can further effectively prevent the lateral displacement of the vehicle platform 510 during travel and improve the stability of the vehicle platform 510 during travel.

[0094] Furthermore, the axles of the first and second lateral wheels are very close to each other in the horizontal direction (almost vertically aligned). When the vehicle platform 510 tends to tilt outward, the first and second lateral wheels generate strong opposing torques between the upper and lower track beams 220, respectively, thus effectively resisting the tilting moment of the vehicle platform 510. Moreover, the small gap between the axles of the first and second lateral wheels maximizes the effect of the torque arm in the vertical direction, which is a key mechanical design feature for preventing tilting.

[0095] In some embodiments, the ratio L4 between the length of the upper wheel seat 5311 and the length of the vehicle platform 510 is 0.2-0.4. When the value of L4 decreases, the distance between the front pillar 110 and the rear pillar 120 increases.

[0096] The value of L4 directly determines the relative length of the cantilever section of the vehicle platform 510. When L4 decreases (e.g., from 0.4 to 0.2), the length of the upper wheel seat 5311 shortens, and the overhang at the front or rear end of the vehicle platform 510 increases. In this case, the structural deflection caused by the cantilever effect is compensated by increasing the distance between the front and rear columns (i.e., the garage depth), thereby preventing the vehicle platform 510 from sagging due to excessive overhang and reducing the load concentration per unit length of the vehicle platform 510. Furthermore, when L4 decreases, L2 (the distance from the front column to the vertical foot of the supporting column) needs to be increased simultaneously to ensure that the vehicle platform 510 does not interfere with the supporting column 130 when rotating (e.g., when L4 = 0.2, L2 needs to be ≥ 2.8 meters). Moreover, the range of L4, through the inverse relationship between overhang length and support span, achieves the optimal solution for the garage under the stiffness-space-cost triangle constraint, which is the core innovation of the parametric design of the multi-level parking garage.

[0097] In some embodiments, the upper connecting beam 421 and the lower connecting beam 422 are of equal length, and the length of the upper connecting beam 421 extending out of the turntable base 410 is less than the thickness of the front column 110.

[0098] On the one hand, the upper connecting beam 421 and the lower connecting beam 422 are set to the same length, which simplifies the processing technology. The upper and lower connecting beams can be manufactured using the same mold or production line, reducing production costs and ensuring that the traveling track 200 can be synchronously aligned with the connecting track 420. On the other hand, the extension length of the upper connecting beam 421 does not exceed the thickness of the front column 110, which can avoid interference between the upper connecting beam 421 and the lower connecting beam 422 and the upper track beam 210 and the lower track beam 220 when the upper connecting beam 421 and the lower connecting beam 422 rotate to the side of the front column 110, thereby ensuring a smooth and accurate connection between the connecting track 420 and the traveling track 200.

[0099] In some embodiments, refer to Figure 18 and Figure 19As shown, the upper connecting beam 421 includes a horizontal track plate 4211, a first vertical track plate 4212 disposed on the front side of the top of the horizontal track plate 4211, and a second vertical track plate 4213 disposed on the front side of the bottom of the horizontal track plate 4211. The first vertical track plate 4212 and the horizontal track plate 4211 enclose each other to form an upper track groove. The second vertical track plate 4213 has a clearance hole (not marked in the figure). The stop unit 450 includes a fixing plate 45 connected to the bottom of the horizontal track plate 4211. 1. A rotating baffle 452 is rotatably connected to the fixed plate 451, and the rotating baffle 452 has a vertical section and an eccentric section connected to each other. The eccentric section corresponds to the clearance hole, and the mass of the eccentric section is greater than the mass of the vertical section, so that the rotating baffle 452 has a tendency to rotate toward the turntable base 410. Furthermore, the two ends of the horizontal track plate 4211 are provided with stop grooves that are adapted to the vertical section. Under the action of gravity, the vertical section contacts the inner wall of the stop groove, so that the center line of the vertical section is parallel to the center line of the turntable base 410.

[0100] The horizontal track plate 4211 and the first vertical track plate 4212 together form the upper track groove, providing a clear movement trajectory and support space for the carrying travel unit 531. This allows the vehicle platform 500 to run stably along the upper track groove during entry and exit from the lifting turntable 400, reducing shaking and friction during operation and improving operational smoothness and reliability. The second vertical track plate further strengthens the structural strength and load-bearing capacity of the upper connecting beam 421. The second vertical track plate 4213, together with the horizontal track plate 4211 and the first vertical track plate 4212, forms a more stable frame structure, better supporting the weight of the vehicle platform 500 and ensuring stability during lifting and transfer. The clearance holes in the second vertical track plate 4213 correspond to the eccentric section of the rotating baffle 452, providing sufficient space for the rotation of the eccentric section, avoiding collisions and interference between components, and allowing the stop unit 450 to move freely and flexibly, ensuring the normal operation of the lifting turntable 400 and the realization of its limiting function.

[0101] When the stop unit 450 separates from the trigger unit 460, the eccentric section, due to its larger mass, can drive the vertical section to return to its original position within the upper track groove, thus automatically narrowing and limiting the opening of the upper track groove. When it is necessary to widen the opening, the trigger unit 460 pushes against the eccentric section, allowing it to rotate against gravity. This flexible and accurate movement ensures the convenience and safety of the vehicle platform 500 entering and exiting the lifting turntable 400. Furthermore, under the influence of gravity, the vertical section is in close contact with the inner wall of the stop groove. This design ensures the precise position of the stop unit 450 in its initial state, providing a reliable guarantee for the accurate parking and limiting of the vehicle platform 500, and improving the operational accuracy of the automated parking system.

[0102] In some embodiments, refer to Figure 20As shown, the trigger unit 460 includes a mounting plate 461 and a trigger plate 462 that is perpendicularly connected to the mounting plate 461. The eccentric section has a groove on the side facing the turntable base 410 that is adapted to the trigger plate 462 so that the cross-sectional shape of the eccentric section is hook-shaped.

[0103] On the one hand, the trigger unit 460, formed by the vertical connection of the mounting plate 461 and the trigger plate 462, has a simple and stable structure. The trigger plate 462 is compatible with the groove in the eccentric section of the rotating baffle 452. When the connecting track 420 rotates and the eccentric section approaches the trigger plate 462, the trigger plate 462 can smoothly enter the groove, achieving effective pressure control of the rotating baffle 452. The hook-shaped design of the groove increases the contact area and friction, ensuring that the rotating baffle 452 will not easily slip during pressure control, thus improving the reliability of the trigger. On the other hand, the matching design of the groove and the trigger plate 462 can disperse the contact stress between the rotating baffle 452 and the trigger plate 462, reducing wear on the trigger plate 462 and the eccentric section during long-term use and extending the lifespan of the device.
