Technical Field
[0001] This utility model relates to the field of automated parking system technology, specifically to the frame structure of a modular lifting and traversing automated parking system. Background Technology
[0002] Multi-level parking garages are special equipment that use mechanical lifting, lateral movement, or circulation devices to store vehicles on multiple levels. They belong to the category of lifting machinery. Their core is to replace traditional flat parking by expanding vertical space and improving land utilization. In order to store more vehicles, multi-level parking garages use lifts to move the vehicle-carrying platforms within the frame laterally.
[0003] The existing patent authorization announcement number CN222333392U discloses a horizontal sliding frame for a three-dimensional parking garage. Through the setting of a limiting structure, when a vehicle drives into the vehicle platform, the servo motor is activated to drive the lifting plate inside the lifting seat to move upward, thereby raising the second partition bar. This works in conjunction with the first partition bar to limit the vehicle and prevent the vehicle from slipping due to parking failure, causing damage to the vehicle.
[0004] When using the above-mentioned patent, the No. 2 barrier and the No. 1 barrier need to abut against the front and rear wheels of the vehicle to effectively limit their movement. However, since the length and wheelbase of different vehicles are different, the distance between the No. 2 barrier and the No. 1 barrier is fixed after the No. 2 barrier is raised, and the distance cannot be flexibly adjusted, which reduces flexibility. Utility Model Content
[0005] The purpose of this utility model is to provide a modular lifting and traversing three-dimensional parking garage frame structure to solve the problem mentioned in the background art that the distance between the second partition and the first partition is fixed after the second partition is raised, and the distance cannot be flexibly adjusted, thus reducing flexibility.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular lifting and sliding three-dimensional parking garage frame structure, including a frame body, with symmetrical support frames arranged on the inner side of the frame body, a car carrier plate movably installed on the top of the support frames, and a limiting component arranged on the outside of the car carrier plate; the limiting component includes a guide frame fixedly installed at the bottom of the car carrier plate, an installation groove corresponding to the guide frame opened on the top of the limiting component, two threaded rods symmetrically arranged on the left and right sides rotatably installed inside the guide frame, two sliding seats threadedly connected to the outside of each of the two threaded rods, the two sliding seats respectively movably engaged with the left and right sides in the installation groove, a connecting plate located in the installation groove connected to the top of each of the two sliding seats, a rotating rod movably hinged to the outside of the connecting plate, a toothed groove provided on the outer side wall of the rotating rod, a partition bar fixedly connected to the end of the rotating rod away from the connecting plate, a transmission gear meshing with the toothed groove rotatably installed inside the lower part of the connecting plate, and a motor connected to the transmission gear fixedly installed on the outside of the connecting plate.
[0007] Preferably, a sprocket located inside a guide frame is fixedly installed at one end of each of the two threaded rods, a transmission chain is movably installed on the outside of the sprocket, and a reduction motor connected to one of the threaded rods is fixedly installed on the outside of the guide frame.
[0008] Preferably, a partition is fixedly installed on the top of the vehicle platform, and the partition is located on the side away from the mounting groove.
[0009] Preferably, the second partition is adapted to the mounting groove, and the second partition can be accommodated in the mounting groove.
[0010] Preferably, a slide is fixedly connected to both the front and rear sides of the bottom of the vehicle platform, and a slide rail with an open end is provided on the top of the support frame. The slide is movably engaged inside the slide rail. A roller is rotatably installed on the inner side of the slide. A pin hole is fixedly connected to the top of the inner side of the slide. A touch sensor is fixedly installed at the end of the slide rail away from the opening, and an electromagnetic pin is fixedly installed at the bottom of the slide rail and engaged in the pin hole.
[0011] Preferably, the roller is located on the inner side of the carriage, and the pin holes are equidistant from each other along the length of the carriage, with the rollers being offset from each other.
[0012] Preferably, the electromagnetic pin is provided in correspondence with the pin hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The electric motor drives the transmission gear to rotate and engages with the tooth groove to drive the rotating rod and the second partition to rotate and rise from the mounting groove. By driving the threaded rods on both sides to rotate synchronously, the sliding seats on the left and right sides are pushed to slide along the mounting groove towards the vehicle wheel, which drives the connecting plate and the second partition to move together. The second partition rests on the tire on the side of the vehicle away from the first partition, so that it can be flexibly adjusted according to the length and wheelbase of the vehicle, thus enhancing its flexibility and adaptability.
[0015] 2. After the carriage is inserted into the slide rail, it will press and trigger the touch sensor when it moves to the designated position within the slide rail.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a modular lifting and sliding three-dimensional parking garage frame structure, including a frame body 1, with symmetrical support frames 2 arranged on the inner side of the frame body 1, a car carrier plate 3 movably installed on the top of the support frames 2, and a limiting component 4 arranged on the outside of the car carrier plate 3; the limiting component 4 includes a guide frame 41 fixedly installed at the bottom of the car carrier plate 3, and an installation groove 31 corresponding to the guide frame 41 is opened on the top of the limiting component 4; two threaded rods 42 symmetrically arranged on the left and right are rotatably installed inside the guide frame 41, and two sliding seats 43 are threadedly connected to the outside of the two threaded rods 42; the two sliding seats 43 are respectively movably engaged on the left and right sides of the installation groove 31; the top of each of the two sliding seats 43 is connected to a connecting plate 44 located in the installation groove 31, and a rotating rod 45 is movably hinged to the outside of the connecting plate 44. The outer wall of the rotating rod 45 is provided with a toothed groove 46. The end of the rotating rod 45 away from the connecting plate 44 is fixedly connected to the second partition 49. The lower inner part of the connecting plate 44 is rotatably installed with a transmission gear 47 that meshes with the toothed groove 46. The outside of the connecting plate 44 is fixedly installed with a motor 48 connected to the transmission gear 47. The motors 48 on both sides drive the transmission gears 47 on both sides to rotate and engage with the toothed groove 46 to drive the rotating rod 45 and the second partition 49 to rotate and rise from the mounting groove 31. By driving the threaded rods 42 on both sides to rotate synchronously, the sliding seats 43 on the left and right sides are pushed to slide along the mounting groove 31 towards the vehicle wheel, which drives the connecting plate 44 and the second partition 49 to move together. The second partition 49 abuts against the tire on the side of the vehicle away from the first partition 32, so that it can be flexibly adjusted according to the length and wheelbase of the vehicle, thus enhancing its flexibility and adaptability.
[0024] The limit component 4 is powered by connecting to the hoist during use and is pulled out after the car carrier plate 3 is placed. The motor 48 is a permanent magnet synchronous motor. After power is cut off, it can achieve self-locking through the magnetic field generated by the permanent magnet, and work with the mechanical brake to completely fix the rotor position, ensuring that the position of the second partition 49 is fixed.
[0025] The main frame 1 adopts a modular design, which is mainly composed of multiple standard steel components connected by high-strength bolts. After each component is prefabricated in the factory, it can be flexibly combined and spliced according to the actual site requirements, which greatly shortens the on-site installation cycle. The modular design makes it more convenient for the expansion, renovation or relocation of the garage in the later stage. Adjustments can be made by simply disassembling the corresponding modules, which reduces maintenance costs and the impact of secondary renovations on the site.
[0026] One end of each of the two threaded rods 42 is fixedly mounted with a sprocket 410 located inside the guide frame 41. A transmission chain 411 is movably mounted on the outside of the sprocket 410. A reduction motor 412 connected to one of the threaded rods 42 is fixedly mounted on the outside of the guide frame 41. When the reduction motor 412 is working, it drives the threaded rod 42 connected to it to rotate. The threaded rod 42 drives the other threaded rod 42 to rotate synchronously through the cooperation of the sprocket 410 and the transmission chain 411, so as to realize that the two threaded rods 42 rotate in the same direction and at the same speed. This ensures that the sliding seats 43 on the left and right sides can maintain a stable and synchronous movement state in the mounting groove 31 of the guide frame 41, providing stable power transmission and motion control for the second partition 49 to accurately press against the vehicle tire.
[0027] A first partition 32 is fixedly installed on the top of the vehicle carrier 3. The first partition 32 is located away from the mounting slot 31. Its main function is to limit the rear position of the parked vehicle. The height design of the first partition 32 fully considers the tire size of different vehicle models, ensuring that it can effectively prevent vehicle displacement without interfering with the normal parking and departure of the vehicle. During the use of the vehicle carrier 3, the first partition 32 and the second partition 49 work together to form double protection from both the front and rear ends of the vehicle, improving the safety of vehicle parking.
[0028] The second partition 49 is adapted to the mounting groove 31. The second partition 49 can be accommodated in the mounting groove 31. When the vehicle leaves the vehicle platform 3, the second partition 49 can be completely retracted into the mounting groove 31 to prevent it from protruding from the surface of the vehicle platform 3 and causing scratches to the vehicle tires or chassis.
[0029] Please see Figure 1 , Figure 2 and Figure 5 The vehicle platform 3 has a slide 33 fixedly connected to both the front and rear sides of its bottom. The top of the support frame 2 is provided with a slide rail 21 with one end open. The slide 33 is movably engaged inside the slide rail 21. A roller 34 is rotatably installed on the inner side of the slide 33. A pin hole 35 is fixedly connected to the top of the inner side of the slide 33. A touch sensor 22 is fixedly installed at the end of the slide rail 21 away from the opening. An electromagnetic pin 23 is fixedly installed at the bottom of the slide rail 21 and engaged in the pin hole 35. After the slide 33 is engaged in the slide rail 21, when the slide 33 is pushed to the designated position in the slide rail 21, it squeezes and triggers the touch sensor 22. After the touch sensor 22 is triggered, the electromagnetic pin 23 extends and engages in the pin hole 35, thereby limiting the position of the vehicle platform 3 and enhancing the stability of the placement.
[0030] The roller 34 is located inside the slide 33 and is equidistantly provided with pin holes 35 along the length of the slide 33. The roller 34 is offset from the pin holes 35. The setting of the roller 34 can transform the sliding friction between the slide 33 and the slide rail 21 into rolling friction, effectively reducing the resistance when the slide 33 moves in the slide rail 21, making the pushing process of the car plate 3 smoother and more stable, reducing wear between components, and extending the service life of the device. The offset design of the pin holes 35 and the roller 34 can avoid mutual interference between the two in the structural layout, ensuring that the electromagnetic pin 23 can accurately and smoothly engage with the pin holes 35 when it extends.
[0031] The electromagnetic pin 23 is configured with a diameter slightly smaller than that of the pin hole 35 to allow for a certain assembly gap. This prevents the electromagnetic pin 23 from getting stuck and unable to extend or retract smoothly due to machining errors or thermal expansion and contraction of the parts. The electromagnetic pin 23 is electrically connected to an external control terminal. After receiving the trigger signal from the touch sensor 22, the control terminal energizes the electromagnetic pin 23. The extension and retraction stroke of the electromagnetic pin 23 is calculated to ensure that it can fully extend and penetrate into the pin hole 35 after the touch sensor 22 is triggered, forming a stable mechanical limit. At the same time, it can quickly retract when the limit needs to be released, without affecting the normal movement of the vehicle platform 3.
[0032] Working principle: During use, the vehicle is positioned on the vehicle carrier 3, with one end of its wheel abutting against the first partition 32 to ensure it is in place. Then, the control motor 48 drives the transmission gear 47 to rotate. The synchronous rotation of the left and right motors 48 drives the transmission gear 47 to engage with the tooth groove 46, causing the rotating rod 45 and the second partition 49 to rotate and rise from the mounting groove 31. Then, the control reduction motor 412 drives the threaded rod 42 connected to it to rotate. The two threaded rods 42 achieve synchronous rotation through the transmission of the sprocket 410 and the transmission chain 411, driving the left and right sliding seats 43 to slide along the mounting groove 31 towards the vehicle wheel. This synchronously drives the connecting plate 44 and the second partition 49 to move together. The second partition 49 abuts against the tire on the side of the vehicle away from the first partition 32, thus allowing for flexible adjustment according to the vehicle's length and wheelbase, improving flexibility and adaptability.
[0033] The vehicle platform 3 is lifted to the corresponding position of the frame body 1 by the hoist and pushed along the opening side of the slide rail 21. The slide 33 is then inserted into the slide rail 21 and pushed into place as the slide 33 is located in the slide rail 21, which triggers the touch sensor 22. The touch sensor 22 is triggered to generate an electrical signal to the external control terminal. The electromagnetic pin 23 is then extended and inserted into the pin hole 35 to limit the position of the vehicle platform 3, thereby improving the placement stability. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
