Description

Technical Field

[0001] This application relates to the field of parking station equipment technology, specifically to a vehicle platform assembly and a parking tower. Background Technology

[0002] Currently, vertical lift parking equipment is commonly referred to as parking tower garages. Most common parking tower garages use lifts to transport vehicles to designated floors, and a storage and retrieval mechanism drives the movement of vehicle-carrying platforms to achieve vehicle storage and retrieval operations. Once the vehicle-carrying platform reaches the target position on the parking platform, it needs to be locked to prevent it from sliding. Existing parking tower garages typically use locking hook mechanisms to lock the vehicle-carrying platforms, but this requires corresponding electric, hydraulic, or pneumatic drive mechanisms to operate the locking hook mechanism. The overall structure and control are relatively complex, resulting in poor operational convenience. Unlocking is required before vehicle retrieval can be performed, affecting work efficiency. Furthermore, if the drive mechanism malfunctions, the locking mechanism will fail, posing a safety hazard. Utility Model Content

[0038] The vehicle carrier assembly provided in this application can be applied in parking tower garages to form a three-dimensional parking system with multiple parking platforms. By setting vehicle carriers on the parking platform and simultaneously installing a lifting device with a vehicle retrieval and placement component in the lifting channel, the lifting device moves vertically to the target floor height. The vehicle retrieval and placement component then engages with the vehicle carrier on the corresponding floor parking platform, driving the vehicle carrier body to move horizontally. This allows the vehicle carrier to move from the parking platform to the lifting device, or vice versa. The vehicle carrier carries the vehicle, allowing it to move along with the vehicle carrier under the drive of the vehicle retrieval and placement component, thus enabling vehicle retrieval and placement operations. The vehicle carrier assembly includes a locking device that mechanically locks the vehicle carrier body through the abutment between a moving part and a stop part, eliminating the need for a corresponding drive mechanism. This device also engages with an unlocking component on the vehicle retrieval and placement component, allowing the unlocking component to unlock the moving part during vehicle retrieval and placement operations.

[0039] The following describes some embodiments of the vehicle platform assembly and parking tower provided in this application, with reference to the accompanying drawings.

[0040] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the vehicle carrier assembly 400 includes a vehicle carrier body 420 and a locking device 430. The vehicle carrier body 420 is used to carry vehicles. When the vehicle carrier assembly 400 is applied to the parking tower 100, the vehicle carrier body 420 can be set on the parking platform 120 of the parking tower 100 and can move along a first horizontal direction under the drive of the vehicle retrieval assembly 23 of the parking tower 100 to transport the carried vehicle to the lifting device 21, or to transport the carried vehicle from the lifting device 21 to the parking platform 120, thereby realizing vehicle retrieval and release operations. The locking device 430 is used to lock and limit the vehicle carrier body 420; the locking device 430 includes a movable member 431, a stop member 433, and an unlocking member 432. The stop member 433 is connected to the bottom of the vehicle carrier, while the movable member 431 is correspondingly set on the parking platform and rotatably connected to the parking platform. The unlocking member 432 can be set on the vehicle retrieval assembly 23. When the vehicle carrier plate 420 enters the target position of the parking platform, the movable part 431 can rotate to a state of abutment and locking with the stop part 433, such as Figure 2 The state shown in the diagram prevents the vehicle platform body 420 from moving toward the vehicle pick-up and drop-off assembly 23; when a vehicle pick-up and drop-off operation is performed, the vehicle pick-up and drop-off assembly 23 drives the unlocking member 432 toward the vehicle platform body 420, so as to release the abutment and locking state between the moving member 431 and the stop member 433 by using the unlocking member 432, such as Figure 3 The state shown in the figure allows the vehicle platform body 420 to be unlocked and move under the drive of the vehicle pick-up and drop-off assembly 23.

[0041] It is understandable that existing vehicle carriers usually require a dedicated drive mechanism to drive the locking mechanism (such as a locking hook structure), which is relatively complex and requires corresponding electrical control lines, air lines or oil lines. Moreover, if the drive mechanism malfunctions, the locking mechanism will fail, which can easily lead to safety hazards.

[0042] In this embodiment, the vehicle carrier assembly 400, through improvements and optimizations to its structure and locking method, utilizes a movable component 431 and a stop component 433 to form a mechanical lock. This eliminates the need for a corresponding drive mechanism, simplifying the structure and reducing safety hazards. When applied in parking tower garages, it can cooperate with the unlocking component 432 mounted on the vehicle retrieval assembly 23, performing unlocking operations simultaneously with vehicle retrieval, thus improving the efficiency of vehicle retrieval. Furthermore, the movable component 431 can rotate vertically, horizontally, or at a certain angle to the horizontal plane. Correspondingly, the stop component 433 and the unlocking component 432 are positioned in the same direction as the movable component 431 to ensure proper locking and unlocking.

[0043] It should be noted that when applied in the parking tower 100, the vehicle platform body 420 is set horizontally, and the first horizontal direction is the direction of movement of the vehicle platform body 420. When carrying a vehicle, the vehicle can be set on the vehicle platform body 420 along the first horizontal direction or along the second horizontal direction, which is perpendicular to the first horizontal direction, according to actual usage needs. Of course, the vehicle can also be set on the vehicle platform body 420 at a certain angle.

[0044] In further embodiments of this application, such as Figures 1 to 3 As shown, in the first horizontal direction, the end of the vehicle carrier body 420 that mates with the vehicle pick-up and drop-off assembly 23 is the mating end 422; correspondingly, the stop 433 of the locking device 430 is located at the bottom of the vehicle carrier body 420 near the mating end 422, and the movable member 431 is located on the side of the stop 433 facing the mating end 422, so that when the vehicle pick-up and drop-off assembly 23 mates with the vehicle carrier body 420, the movable member 431 is located on the side near the vehicle pick-up and drop-off assembly 23, and the horizontal distance between the movable member 431 and the unlocking member 432 on the vehicle pick-up and drop-off assembly 23 can be shortened, facilitating the unlocking operation. Wherein, as Figure 2 and Figure 3 In the example, the rotation center of the movable part 431 is set along the second horizontal direction, which is perpendicular to the first horizontal direction, so that the movable part 431 can rotate in the vertical plane. On the one hand, it can reduce the space occupied in the horizontal direction, which is conducive to the assembly and arrangement in a limited space and avoids interference with other surrounding components or structures. On the other hand, the rotation of the movable part 431 can be achieved by using gravity.

[0045] Furthermore, such as Figure 2 and Figure 3In the example, the movable member 431 has a first end 4311 and a second end 4312 corresponding to the rotation center, forming a lever structure. The first end 4311 is located at the end of the movable member 431 away from the stop member 433, and the second end 4312 is located at the end of the movable member 431 closer to the stop member 433. Under the action of gravity, the torque of the first end 4311 of the movable member 431 is greater than the torque of the second end 4312, causing the first end 4311 of the movable member 431 to droop in its natural state, while the second end 4312 tilts upward, so that the second end 4312 abuts against the stop member 433 above and forms a locking state. That is, the locking between the movable member 431 and the stop member 433 is achieved by using gravity, without the need for a separate drive mechanism. The overall structure is relatively simple and easy to implement. In the vertical direction, there is a height gap between the lowest point of the stop 433 and the rotation center of the movable member 431, allowing the unlocking member 432 to pass through. When the unlocking member 432 moves toward the vehicle platform body 420 with the vehicle pick-up and drop-off assembly 23, the unlocking member 432 can contact the upward-curved movable member 431 and push the movable member 431 down to the state of disengaging from the stop 433 through the pushing action, thereby releasing the locking state between the movable member 431 and the stop 433.

[0046] Furthermore, such as Figures 2 to 4 In the example, movable component 431 is connected to a rotating base 4314, and the movable component 431 and the rotating base 4314 are rotatably connected. During assembly, the rotating base 4314 can be connected and fixed to the parking platform 120 so that the movable component 431 forms a lever structure, allowing it to rotate relative to the rotation center. A counterweight 4313 is connected to the first end 4311 of the movable component 431 to increase the weight of the first end 4311, so that in its natural state, the torque of the first end 4311 is greater than the torque of the second end 4312, causing the second end 4312 to tilt upwards. Since torque equals the product of force and lever arm, given the above torque relationship, the greater the weight on the first end 4311, the smaller the required lever arm. Figure 4 In the example, the lever arm of the second end 4312 can be shortened, thereby adapting to the limited space below the vehicle platform body 420, which is more conducive to spatial layout and prevents interference with other components.

[0047] Furthermore, such as Figures 2 to 4 In the example, the stop 433 has a sloped structure 4331 on the side facing the movable member 431. The sloped structure 4331 is adapted to the upward angle of the second end 4312 of the movable member 431 to form a surface contact between the second end 4312 and the sloped structure 4331. Figure 4The state shown in the figure increases the contact area, making the locking state more stable and the force relatively uniform. The stop 433 can adopt an inverted triangular plate structure and be fixed to the bottom of the vehicle platform body 420 by welding, which is convenient for processing and forming; the movable part 431 can specifically adopt a plate structure and be connected to the parking platform 120 by rotating the base 4314.

[0048] Correspondingly, such as Figures 2 to 3 As shown, the unlocking component 432 has a horizontal pressure plate structure, which matches the movable component 431. When the vehicle pick-up and drop-off assembly 23 and the parking platform 120 are at the docking height, the unlocking component 432 can move along the first horizontal direction toward the vehicle platform assembly 400 together with the vehicle pick-up and drop-off assembly 23, so that the horizontal pressure plate structure of the unlocking component 432 passes through the height gap between the corresponding stop 433 and the rotation center of the movable component 431 along the first horizontal direction, so as to press down the second end 4312 of the movable component 431 that is tilted upward to separate from the stop 433, thereby releasing the locking state of the vehicle platform body 420, so that the vehicle platform body 420 can move along the first horizontal direction to the lifting device 21 under the drive of the vehicle pick-up and drop-off assembly 23. It is understandable that when the vehicle platform body 420 moves from the lifting device 21 to the parking platform 120 under the drive of the vehicle loading and unloading assembly 23, the movable part 431 can also be pushed down by the horizontal pressure plate structure of the unlocking part 432 to avoid interference with the stop part 433 or the vehicle platform body 420. The horizontal pressure plate structure of the unlocking part 432 can be as follows: Figure 5 The L-shaped plate structure shown in the figure facilitates connection and fixation. At the same time, it can extend a certain distance beyond the end face of the friction wheel mechanism 234 in the first horizontal direction. Before the friction wheel mechanism 234 and the friction plate 421 are engaged, the horizontal pressure plate structure can press down the movable part 431 and release the locking state of the vehicle plate body 420, so as to realize the organic coordination of unlocking operation and vehicle loading and unloading operation.

[0049] An embodiment of the second aspect of this application provides a parking tower garage, such as Figures 1 to 5As shown, the parking tower 100 includes a tower frame 1, a lifting device 21, a vehicle retrieval assembly 23, a controller, and a vehicle platform assembly 400 as described in any of the embodiments of the first aspect above. The tower frame 1 includes a main frame 11 extending along the height direction and a side frame 12. The side frame 12 is connected to the side of the main frame 11, and the main frame 11 is connected to the side frame 12 on at least one side in the horizontal direction. The main frame 11 forms a lifting channel 111 that runs through the height direction. The side frame 12 has multiple parking platforms 120 spaced apart along the height direction, and each parking platform 120 is provided with a vehicle platform assembly 400 to carry vehicles through the vehicle platform body 420 of the vehicle platform assembly 400. The vehicle platform body 420 is movable relative to the parking platform 120 in a first horizontal direction. At least a portion of the lifting device 21 is disposed in the lifting channel 111 for lifting movement. The vehicle retrieval assembly 23 is disposed on the lifting device 21. The vehicle retrieval assembly 23 can move with the lifting device 21 to a height corresponding to any parking platform 120, and can form a transmission engagement with the vehicle carrier plate body 420 on the corresponding parking platform 120 to drive the vehicle carrier plate body 420 from the parking platform 120 to the lifting device 21, or drive the vehicle carrier plate body 420 from the lifting device 21 to the corresponding parking platform 120, so that the vehicle carrier plate body 420 carries the vehicle and moves together to realize the vehicle retrieval operation. The controller is connected to the lifting device 21 and the vehicle retrieval assembly 23 to control the lifting device 21 to perform lifting movement and control the vehicle retrieval assembly 23 to perform vehicle retrieval operation.

[0050] Among them, such as Figure 5 , Figure 6 As shown, each parking platform 120 is equipped with a movable component 431, and the corresponding vehicle carrier body 420 is equipped with a stop component 433. Correspondingly, an unlocking component 432 is connected to the vehicle retrieval assembly 23 and corresponds to the movable component 431 in the first horizontal direction. When the vehicle retrieval assembly 23 moves towards the parking platform 120 in the first horizontal direction, it drives the unlocking component 432 to approach the movable component 431. When the unlocking component 432 contacts the movable component 431, it generates a horizontal thrust. As the unlocking component 432 continues to move, the movable component 431 rotates and releases the abutment and locking state between itself and the stop component 433, thereby realizing the unlocking operation.

[0051] In practical applications, multiple sets of stop members 433 and movable members 431 can be spaced apart in the second horizontal direction to enable the vehicle platform body 420 to form a multi-point lock. Correspondingly, a corresponding number of unlocking members 432 are provided in the vehicle loading and unloading assembly 23, and are respectively provided with each set of stop members 433 and movable members 431. In addition, as Figure 6In the example shown, when side frames 12 are provided on both sides of the main frame 11, each parking platform 120 in the side frames 12 is provided with at least one set of stop members 433 and movable members 431. Correspondingly, the vehicle retrieval assembly 23 is provided with unlocking members 432 at both ends in the first horizontal direction to match the movable members 431 and stop members 433 on both sides respectively. In use, when the vehicle retrieval assembly 23 performs a vehicle retrieval operation on one side of the vehicle platform body 420, it is only necessary to use the unlocking member 432 on that side to unlock the corresponding movable member 431 and stop member 433. The movable member 431 and stop member 433 on the other side remain locked and do not require unlocking. This achieves a one-to-one correspondence between the vehicle retrieval operation and the unlocking operation of the locking device 430, effectively preventing the safety risks caused by simultaneously unlocking the locking devices 430 of multiple vehicle platform bodies 420.

[0052] In further embodiments of this application, such as Figures 5 to 7 As shown, the bottom of the vehicle carrier plate body 420 has a friction plate 421 extending along a first horizontal direction, and the friction plate 421 is parallel to the vertical plane. Correspondingly, the vehicle pick-up and drop-off assembly 23 specifically includes a vehicle pick-up and drop-off drive mechanism 231, a horizontal movement mechanism 232, a friction wheel drive mechanism 233, and two sets of friction wheel mechanisms 234; the vehicle pick-up and drop-off drive mechanism 231 and the friction wheel drive mechanism 233 are both communicatively connected to the controller to receive control commands from the controller and operate accordingly; the vehicle pick-up and drop-off drive mechanism 231 is drive-connected to the horizontal movement mechanism 232, the friction wheel drive mechanism 233 and the two sets of friction wheel mechanisms 234 are all mounted on the horizontal movement mechanism 232 and can move along the first horizontal direction with the horizontal movement mechanism 232; the two sets of friction wheel mechanisms 234 are spaced apart along a second horizontal direction, and the friction wheel drive mechanism 233 is drive-connected to the two sets of friction wheel mechanisms 234 to drive the friction wheels 2345 of the friction wheel mechanisms 234 to rotate. When the vehicle loading / unloading assembly 23 is in a docking state with the corresponding vehicle carrier body 420, the friction plate 421 of the vehicle carrier body 420 aligns with the gap space between the two sets of friction wheel mechanisms 234. Driven by the horizontal movement mechanism 232, the friction wheel mechanisms 234 move towards the vehicle carrier body 420, causing the friction plate 421 to enter the gap space between the two sets of friction wheel mechanisms 234 and form a rolling engagement with the friction wheel 2345. Figure 8 As shown in the diagram, the friction wheel 2345 rotates to apply friction to the friction plate 421, thereby causing the friction plate 421 and the vehicle carrier plate body 420 to move along the first horizontal direction toward the lifting device 21, thus moving the vehicle carried on the vehicle carrier plate body 420 onto the lifting device 21 to complete the vehicle retrieval operation. Correspondingly, the parking operation only requires reversing the above operation.

[0053] In practical applications, the horizontal motion mechanism 232 can be adopted as follows: Figure 7 The frame structure shown has a rack structure connected to one side. The pick-and-place vehicle drive mechanism 231 can mesh with the rack structure through the gear structure at the output end of the drive motor, forming a gear and rack mechanism 2322. During operation, the output torque of the drive motor is transmitted through the gear and rack mechanism 2322 to drive the frame structure of the horizontal motion mechanism 232 to move along the first horizontal direction. Preferably, as shown... Figure 7 In the example, the frame structure is provided with friction wheel mechanism 234 and corresponding friction wheel drive mechanism 233 at both ends in the first horizontal direction, so as to perform vehicle loading and unloading operations on the vehicle platform body 420 on the side frame 12 on both sides of the main frame 11.

[0054] In addition, the friction wheel mechanism 234 can be specifically adopted as follows: Figure 7 The transmission chain mechanism shown drives the friction wheel 2345. For example, the driving wheel 2342 of the transmission chain mechanism is connected to the friction wheel drive mechanism 233. The driven wheel 2343 of the transmission chain mechanism forms a chain drive with the driving wheel 2342 through the transmission chain 2344. The friction wheel 2345 is coaxially arranged on the driven wheel 2343. The friction wheel drive mechanism 233 drives the friction wheel 2345 to rotate through the transmission chain mechanism. Alternatively, two coaxial gears can be arranged on the driving wheel 2342. One gear meshes with the transmission chain 2344, and the other gear meshes with a gear on the driving wheel 2342 of the corresponding friction wheel mechanism 234. Thus, one friction wheel drive mechanism 233 can simultaneously drive two sets of friction wheel mechanisms 234, and the friction wheels 2345 of the two sets of friction wheel mechanisms 234 can rotate synchronously, which helps to prevent the friction plate 421 from slipping.

[0055] Furthermore, in a specific example, such as Figure 7 In the example shown, the loading and unloading assembly 23 also includes a lateral adjustment mechanism 235, and each friction wheel mechanism 234 has a mounting cover 2341 connected to the horizontal movement mechanism 232. The lateral adjustment mechanism 235 is arranged along a second horizontal direction and passes through the mounting covers 2341 of the corresponding two friction wheel mechanisms 234; both ends of the lateral adjustment mechanism 235 protrude from a corresponding mounting cover 2341, and the ends are connected to adjusting members to adjust the distance between the two mounting covers 2341 in the second horizontal direction. For example, Figure 7In the example, the lateral adjustment mechanism 235 can adopt a threaded crossbar structure 2351. The adjustment components specifically include an adjusting nut 2352 and an elastic buffer 2353. The adjusting nut 2352 is threadedly connected to the crossbar structure 2351. The elastic buffer 2353 is sleeved on the crossbar structure 2351, with both ends abutting against the adjusting nut 2352 and the corresponding mounting cover 2341, respectively. By tightening or loosening the adjusting nut 2352, the distance between the two mounting covers 2341 in the second horizontal direction can be adjusted, thereby adjusting the gap between the two sets of friction wheel mechanisms 234 to match the friction plate 421, ensuring that the friction plate 421 can form a rolling fit after entering the gap space between the two sets of friction wheel mechanisms 234. For example, Figure 7 In the example, the elastic buffer 2353 may specifically take the form of a spring and / or an elastic pad.

[0056] In further embodiments of this application, such as Figure 9 and Figure 10 As shown, the parking tower 100 also includes a positioning device 3, which includes a first positioning element 31 and a plurality of second positioning elements 32. The first positioning element 31 is rotatably set on the lifting device 21 at a position corresponding to the parking platform. The second positioning elements 32 are set on the main frame 11, and a second positioning element 32 is set on the main frame 11 at a position corresponding to each parking platform 120.

[0057] Specifically, the first positioning component 31 includes a locking hook structure 311, a rotation drive mechanism 312, and an elastic reset component 313. The locking hook structure 311 is rotatably connected to the lifting device 21, and the rotation drive mechanism 312 is fixedly connected to the lifting device 21 and communicates with the controller. The rotation drive mechanism 312 is also drively connected to the locking hook structure 311 to drive the locking hook structure 311 to rotate in the vertical plane under the control of the controller. The second positioning component 32 has a locking rod structure 321, which is arranged along the second horizontal direction. When the first positioning component 31 moves with the lifting device 21 to the height corresponding to the second positioning component 32, the locking hook structure 311 rotates under the drive of the rotation drive mechanism 312 to an angle that engages with the locking rod structure 321. As the lifting device 21 moves, the locking hook structure 311 and the locking rod structure 321 form a snap-fit ​​engagement, and the lifting device 21 reaches the target positioning position, enabling it to dock with the vehicle carrier plate body 420 on the corresponding floor for vehicle loading and unloading operations. One end of the elastic reset member 313 is connected to the locking hook structure 311, and the other end is connected to the lifting device 21, so that the locking hook structure 311 is restored to its initial state by the elastic force of the elastic reset member 313. In one specific implementation, such as... Figure 10In the example, the initial state of the locking hook structure 311 is away from the locking bar structure 321. Under the drive of the rotation drive mechanism 312, the locking hook structure 311 rotates towards the locking bar structure 321 (e.g., Figure 10 (Rotating counterclockwise), while simultaneously stretching the elastic reset member 313 to generate elastic tension. When the hook structure 311 is engaged with the locking rod structure 321, the elastic reset member 313 is in a stretched state. When the hook structure 311 is disengaged from the locking rod structure 321, the elastic tension of the elastic reset member 313 drives the hook structure 311 to rotate back to its initial state. In another specific implementation, the initial state of the hook structure 311 is close to the locking rod structure 321. At this time, the elastic reset member 313 is in its natural state. When the hook structure 311 needs to avoid obstacles during the lifting process of the lifting device 21, the rotation drive mechanism 312 drives the hook structure 311 to rotate away from the locking rod structure 321 (e.g., ...). Figure 10 (rotating clockwise), simultaneously compressing the elastic reset member 313 and generating an elastic thrust. When the driving force of the rotation drive mechanism 312 is released, the locking hook structure 311 can rotate towards the locking rod structure 321 under the elastic thrust of the elastic reset member 313 (e.g., rotating clockwise). Figure 10 It rotates counterclockwise to return to its initial state and engages with the locking rod structure 321. The elastic reset element 313 can specifically be a spring.

[0058] In practical applications, the positioning device 3 can also be configured as follows: Figure 10 The first limiting structure 341 and the second limiting structure 342 shown are disposed on the side of the locking hook structure 311 away from the second positioning member 32, and are spaced apart in the height direction. When the locking hook structure 311 rotates in different directions, the first limiting structure 341 and the second limiting structure 342 abut against different positions on the locking hook structure 311 to limit the rotation stroke of the locking hook structure 311, preventing excessive rotation angle from affecting normal use. The first limiting structure 341 and the second limiting structure 342 can be bolts or screws and fixedly connected to the corresponding mounting base, or they can be connected by threads to facilitate position adjustment.

[0059] In further embodiments of this application, such as Figure 1 , Figure 5 , Figure 11 and Figure 12In the example, the side frame 12 of the tower rack 1 specifically includes multiple horizontal frames 121, at least two side columns 122, and multiple side connecting rods 123. At least two side columns 122 are correspondingly located on the sides of the main frame 11, forming a rectangular space with the main frame 11. Multiple horizontal frames 121 are located within the rectangular space between the side columns 122 and the main frame 11, and are spaced apart in the height direction. Each horizontal frame 121 is connected and fixed to the main frame 11 and at least two side columns 122 (e.g., welded or bolted), so that the upper surface of the horizontal frame 121 forms a parking platform 120 for placing the vehicle platform body 420, thereby carrying a vehicle. The side connecting rods 123 connect between the main frame 11 and the side columns 122, or connect between two adjacent side columns 122, to improve the connection strength of the side frame 12. Specifically, the side connecting rods 123 can be as follows: Figure 11 and Figure 12 The tilted setting shown can also be set to a horizontal or vertical state, depending on the specific strength requirements.

[0060] In practical applications, the main frame 11 can be an independent rectangular three-dimensional frame structure, or it can be a structure such as... Figure 11 The structure shown includes two sets of vertical frame structures arranged side by side in the second horizontal direction. Each set of vertical frame structures includes two main columns 112 and multiple main connecting rods 113 arranged horizontally between the two main columns 112. Correspondingly, in the first horizontal direction, side frames 12 are provided on both sides of the main frame 11. The two ends of the two sets of vertical frames are respectively connected and fixed to the horizontal frames 121 of the side frames 12 on both sides, so as to form a lifting channel 111 between the two sets of vertical frames. The main frame 11 has side frames 12 on both sides in the first direction. That is, the tower rack frame 1 mainly includes four main columns 112, four side columns 122, multiple main connecting rods 113, multiple side connecting rods 123, and multiple horizontal frames 121. The bottom of the main column 112 has a mounting base 114. During construction, the aforementioned structural components can be pre-assembled into multiple modular structures, such as the vertical frame and horizontal frame 121, and then transported to the construction site for assembly. This modular assembly construction improves on-site assembly efficiency, shortens the on-site construction cycle, and enables rapid assembly. Compared to the cantilevered frame structures commonly found in existing technologies, the tower garage frame 1 assembled from the structural components in this embodiment has higher structural strength. In particular, the side frame 12, which is used to support vehicles, is not only connected and fixed to the main frame 11 in the horizontal direction, but also connected to the parking platforms 120 of adjacent floors in the vertical direction through columns and side connecting rods 123. The stress distribution of the side frame 12 is relatively more uniform, with stronger load-bearing capacity and higher reliability, making it suitable for widespread application in large-scale multi-level parking tower garages.

[0061] Furthermore, such as Figure 1 , Figure 5 As shown, the lifting device 21 specifically includes a lifting platform 211 and a lifting drive mechanism 212. The lifting platform 211 is installed within the lifting channel 111 of the main frame 11, and the lifting drive mechanism 212 is installed on the top of the main frame 11 and is connected to the lifting platform 211 via a wire rope and pulley mechanism. The lifting drive mechanism 212 is communicatively connected to a controller to drive the lifting platform 211 to move up and down within the lifting channel 111 under the control of the controller. Vertical guide rails can be installed on the main column 112 of the main frame 11, and vertical guide wheels can be correspondingly installed on the lifting platform 211. The vertical guide wheels and vertical guide rails form a rolling engagement to guide the lifting movement of the lifting platform 211, which helps to improve the stability of the lifting platform 211 during movement. Additionally, as... Figure 10 In the example, a horizontal guide rail 124 extending along the first horizontal direction can also be provided on the parking platform 120, and a corresponding horizontal guide wheel 125 can be provided at the bottom of the vehicle platform body 420. The horizontal guide wheel 125 and the horizontal guide rail 124 roll together to guide the vehicle platform body 420.

[0062] In practical applications, the controller can be installed on the tower rack or the lifting device 21, or a separate electrical control cabinet can be installed on the ground to house the controller and related electrical control components and systems. Specifically, the controller can be an independent electrical control component or an electrical control module integrated into the overall control system. The communication connection between the controller and the lifting device 21, the vehicle retrieval assembly 23, and the positioning device can be a wired communication connection or a wireless communication connection, such as WIFI or 4G / 5G communication connections. The specific configuration can be determined according to actual usage needs and will not be elaborated further here.

[0063] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
