Description

Technical Field

[0001] This invention relates to the field of automated parking garage technology, specifically to an automated parking garage and its vehicle platform lateral movement device. Background Technology

[0002] Multi-level parking garages are mechanical or equipment systems used to store and retrieve a large number of vehicles. With their unique characteristic of small average footprint per vehicle, they can resolve the contradiction between the footprint of parking spaces and the commercial space of residential areas and are widely accepted by users.

[0003] Conventional automated parking systems primarily utilize motor-driven lateral movement of vehicle carrier platforms. Vehicles are placed on these platforms, and the motor drives them to a lifting frame. The lifting frame then transports the vehicles to the designated parking level. Both the lifting platform and parking spaces are equipped with guide rails, each with rollers. The rollers on the lifting platform move the vehicle carrier platform towards the parking space, guiding it onto the guide rail. The rollers on the parking space guide rail then move the vehicle carrier platform into the parking space, completing the parking process once it is correctly positioned. However, in this existing technology, the lateral movement of the vehicle carrier platform requires a motor, with one motor installed for each parking space. A chain drive is also necessary to propel the vehicle carrier platform. Each motor and transmission assembly becomes a potential point of failure. The large number of interconnected parts increases production costs, daily maintenance expenses, and the difficulty of installation and maintenance.

[0004] To address the aforementioned problems in the design of the lateral movement mechanism for vehicle loading platforms in conventional automated parking garages, those skilled in the art have made improvements. For example, publication number CN108894560A discloses a mechanical automated parking garage vehicle loading platform lateral movement pulling device and an automated parking garage, including a lifting frame and vehicle loading platforms. The lifting frame is equipped with a pull rod device, which consists of a rotating device, a moving pull rod, and a guide rail. The guide rail of the pull rod device is fixedly connected to both sides of the lifting frame. The moving pull rod is mounted on the guide rail and moves laterally along the guide rail. The rotating device is mounted on the guide rail and rotates around its connection point with the guide rail. One end of the moving pull rod is connected to the edge of the rotating device via a connecting rod, and the other end is equipped with a limiting device for connecting the vehicle loading platform and pulling the vehicle loading platform laterally. The lifting frame is equipped with a drive device that rotates the rotating device. This technology employs a rotating device and a connecting rod-slider structure. The horizontal displacement of the vehicle platform is achieved by driving the linear movement of the horizontal rod through the horizontal rotation of a portion of the connecting rod. In other words, the horizontal rotational motion is converted into horizontal linear motion to achieve the lateral movement of the vehicle platform. Although this can reduce the number of motors and the number of failure points, it requires a large number of lateral movement mechanisms to be arranged on the same plane. Especially in bidirectional drive, this will increase the difficulty of layout in a large structural space. In addition, the combination of this device and the vehicle turning mechanism may cause interference problems. Furthermore, since it converts the horizontal rotational force into the horizontal driving force, the driving power requirement of the drive mechanism is relatively large. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a three-dimensional parking garage and its vehicle platform lateral movement device.

[0006] A vehicle platform lateral movement device for a three-dimensional parking garage according to the present invention includes a lifting frame, a micro-advancing mechanism, and a lateral movement mechanism;

[0007] The lifting frame has first tracks at both ends for sliding the vehicle platform. A second track is provided parallel to each of the two first tracks on the inner side. The two ends of the lower side of the vehicle platform are provided with clamping plates. The clamping plates have U-shaped grooves with openings facing away from the upper surface of the vehicle platform.

[0008] The micro-advancing mechanism includes a micro-advancing drive motor, a transmission assembly, and a support frame. The two ends of the support frame are slidably connected to two second tracks. The micro-advancing drive motor drives the support frame to slide along the second tracks through the transmission assembly.

[0009] The lateral movement mechanism includes a lateral movement drive motor and a hook assembly. The hook assembly is a tracked structure and includes a pin. Two sets of hook assemblies are respectively connected to both ends of the support frame. The lateral movement drive motor drives the two sets of hook assemblies to rotate synchronously.

[0010] After the vehicle platform descends to the side of the lifting frame, the micro-advancing drive motor drives the support frame to move laterally a predetermined distance toward the vehicle platform. Then, the lateral movement drive motor drives the hook assembly to rotate synchronously. As the pin at the end rotates, it engages in the slot during its movement from the lower end to the upper end. The vehicle platform moves onto the first track under the drag of the pin. Driven by the lateral movement drive motor and the micro-advancing drive motor, the vehicle platform moves laterally to the predetermined position of the lifting frame.

[0011] In some embodiments, the transmission assembly includes a first drive sprocket, a first drive chain, and a connector. Two first drive sprockets are symmetrically arranged on the inner walls of the longitudinal beams on both sides of the lifting frame. A micro-advancing drive motor drives one of the first drive sprockets. The first drive chain meshes with both first drive sprockets. The connector connects the first drive chain and the support frame. The micro-advancing drive motor drives the first drive sprocket to rotate. The first drive chain, which rotates with the two first drive sprockets, drives the support frame to move linearly through the connector.

[0012] In some embodiments, the connector includes a connecting rod and a connecting block, the first drive chain is a non-closed structure, the two connecting rods are respectively connected to the two ends of the first drive chain, and the two connecting rods are detachably connected to the support frame through a connecting block.

[0013] In some embodiments, the transmission components are in two sets, with the two sets of transmission components respectively located near both ends of the support frame. The micro-advancing drive motor drives the two sets of transmission components to rotate synchronously, and the two sets of connecting members are respectively connected to the crossbeams located at both ends of the support frame.

[0014] In some embodiments, the hook assembly further includes a support frame, a second drive sprocket, and a second drive chain. The support frame consists of two upright plates connected to the support frame in a parallel and spaced manner. Two second drive sprockets are rotatably connected to both ends of each upright plate. The four second drive sprockets located at the ends of the support frame form a four-wheel structure. Two second drive chains are respectively meshed with two second drive sprockets located at both ends of the upright plates. The ends of the second drive chains are located outside the ends of the support frame. The pin is connected between the two second drive chains.

[0015] In some embodiments, the hook assembly further includes a first tension sprocket, four of which are connected to the support frame in a manner close to the four second drive sprockets, and the second drive chain is tensioned by the first tension sprockets.

[0016] In some embodiments, the hook assembly further includes a second tension sprocket, a third tension sprocket, and an automatic telescopic rod. The two automatic telescopic rods are respectively fixedly connected to the two upright plates of the support frame. The two second tension sprockets are connected in series on a fixed shaft and connected to the two automatic telescopic rods through the fixed shaft. The two third tension sprockets are located below the second tension sprockets. The second drive chain sequentially engages with the second tension sprocket, the third tension sprocket, and the second drive sprocket to form an inverted V-shape. The second tension sprocket automatically moves horizontally through the elastic action of the automatic telescopic rod, thereby automatically tensioning the second drive chain.

[0017] In some embodiments, a slewing mechanism is also included, which is located within the frame of the lifting frame. The slewing mechanism includes a lifting drive motor, a lifting arm, a slewing table, and a slewing drive motor. The lifting drive motor drives and connects to the lifting arm, and multiple lifting arms are connected to the slewing table. The slewing drive motor drives and connects to the slewing table.

[0018] After the vehicle platform is moved onto the lifting frame, the lifting drive motor drives the lifting arm to raise the turntable to a predetermined height. The support plate of the turntable lifts the vehicle platform, and the turntable drive motor drives the turntable to rotate, causing the vehicle platform to turn around.

[0019] In some embodiments, the lifting arm has a gear and rack structure, and there are four sets of lifting arms connected to the four corners of the rotary table.

[0020] The present invention also provides a three-dimensional parking garage, which is formed by the aforementioned three-dimensional parking garage vehicle platform lateral movement device.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The vehicle platform lateral movement device of this application for a three-dimensional parking garage achieves lateral displacement by means of a micro-advancing mechanism assisting the lateral movement mechanism. In the tracked lateral movement mechanism, the pin shaft mounted between the two drive chains engages with the U-shaped slot during the vertical rotation. The arc-shaped movement of the pin shaft at both ends is cleverly used to achieve the towing connection with the vehicle platform. Then, the horizontal movement of the pin shaft in the middle section drags the vehicle platform to complete the lateral movement. Through a simple mechanism design, the lateral movement of the vehicle platform can be completed stably, safely, and efficiently. This solves the problems of high power required by the power equipment, low lateral movement efficiency, and large space occupation of the rotary mechanism in the existing technology that uses a change of horizontal rotational force to horizontal linear drag force to complete the lateral movement operation. This improves the operation efficiency and further reduces the equipment cost.

[0023] 2. The vehicle platform lateral movement device of this application improves the meshing area between the second drive sprocket and the second drive chain by setting a tensioning structure in the hook assembly, thereby enhancing the stability of the vehicle platform lateral movement process.

[0024] 3. The vehicle platform lateral movement device of this application adds a rotation mechanism for turning the vehicle platform, thereby expanding the application scenarios of the device in addition to the function of lateral movement of the vehicle platform. Attached Figure Description

[0040] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention.

[0041] Example 1

[0042] This embodiment provides a vehicle platform lateral movement device for a three-dimensional parking garage, such as... Figure 1-10 As shown, it mainly includes a lifting frame 100, a micro-advancing mechanism 200, and a lateral movement mechanism 300. The lifting frame 100 is the frame section in the automated parking garage used for vehicle entry and exit. One or both sides of it are the frame sections that support vehicles. This embodiment takes a lifting frame 100 with both sides supporting vehicles as an example for the following description. Figure 1 As shown, the lifting frame 100 has first tracks 110 at both ends. Here, "both ends of the lifting frame 100" refers to its length, i.e., the direction from front to rear of a vehicle when it is supported. Vehicle-carrying platforms 400 located on the side frames of the lifting frame 100 slide onto the lifting frame 100 via the first tracks 110. Then, vehicles on the vehicle-carrying platforms 400 drive off the lifting frame 100 or external vehicles drive onto the vehicle-carrying platforms 400 on the lifting frame 100. The first track 110 has a groove-shaped structure, including a crossbeam serving as the track and limiting strips on both sides of the upper surface of the crossbeam. The limiting strips ensure the linear movement of the rollers at the bottom of the vehicle-carrying platform 400. The lifting frame 100 also has two second tracks 120, which are respectively positioned close to the two first tracks 110 at both ends. The second tracks 120 are formed by multiple spaced rollers rotatably connected between the two platforms. Figure 8 As shown, two retaining plates 410 are provided below the side longitudinal beams of the vehicle platform 400. The two retaining plates 410 are located near the two ends of the side longitudinal beams, which are the outermost supporting longitudinal beams of the vehicle platform 400. The retaining plates 410 are provided with U-shaped slots 411, with the openings of the U-shaped slots 411 facing downwards. In this embodiment, retaining plates 410 are provided below the side longitudinal beams on both sides of the vehicle platform 400, that is, four retaining plates 410 are provided near the four corners of the vehicle platform 400.

[0043] like Figure 1-5As shown, the micro-advancing mechanism 200 includes a micro-advancing drive motor 210, a transmission assembly 220, and a support frame 230. The support frame 230 is a rectangular frame structure, with the crossbeams at both ends of the support frame 230 resting on two second tracks 120. The micro-advancing drive motor 210 is supported within the frame of the lifting stand 100 via a bracket structure, and the micro-advancing drive motor 210 drives the support frame 230 to slide linearly on the second tracks 120 via the transmission assembly 220. The transmission assembly 220 mainly includes a first drive sprocket 221, a first drive chain 222, and a connector 223. The two first drive sprockets 221 are respectively connected to the side longitudinal beams on both sides of the lifting stand 100 in a face-to-face structure. The first drive chain 222 is engaged with the two first drive sprockets 221, and the micro-advancing drive motor 210 drives one of the first drive sprockets 221. The first drive chain 222 drives the support frame 230 to move laterally via the connector 223. The driving method is as follows: when the micro-drive motor 210 drives the first drive sprocket 221 to rotate clockwise, the first drive chain 222 drives the support frame 230 to slide to the right along the second track 120 via the connector 223; when the micro-drive motor 210 drives the first drive sprocket 221 to rotate counterclockwise, the support frame 230 slides to the left along the second track 120. In this embodiment, the connector 223 consists of connecting rods 2231 and connecting blocks 2232. At this time, the first drive chain 222 has a non-closed structure, meaning it is linear and not a closed loop. The two connecting rods 2231 are connected to both ends of the first drive chain 222, and the two connecting blocks 2232 are respectively sleeved on the two connecting rods 2231. Simultaneously, the two connecting blocks 2232 are connected to the frame structure of the support frame 230. The connecting rod 2231 and the connecting block 2232 can be detachably connected by a threaded connection, which can effectively facilitate the disassembly, replacement and maintenance of parts. In this embodiment, there are two sets of transmission components 220, which are respectively set near the crossbeams at both ends of the support frame 230. The micro-advancing drive motor 210 drives two first drive sprockets 221 located on the same side of the two sets of transmission components 220 to rotate synchronously through the drive shaft. The connecting block 2232 is connected to the crossbeams at both ends of the support frame 230. By setting two sets of transmission components 220, the smoothness of the support frame 230 sliding along the second track 120 can be effectively improved.

[0044] The traversing mechanism 300 mainly includes a traversing drive motor 310 and hook-and-hook assemblies 320 connected to the traversing drive motor 310. There are two sets of hook-and-hook assemblies 320, each connected to and moving with the support frame 230. The hook-and-hook assembly 320 has a tracked structure design. Figure 3 , 6As shown in Figure 7, the main components include a pin 321, a support frame 322, a second drive sprocket 323, and a second drive chain 324. The support frame 322 consists of two parallel vertical plates 3221 connected at intervals to the longitudinal beams on both sides of the support frame 230. The two support frames 322 are respectively positioned near the crossbeams of the beam segment of the support frame 230. Two second drive sprockets 323 are rotatably connected to both ends of each vertical plate 3221. The second drive sprockets 323 are parallel to the vertical plate 3221, thus forming a four-wheel structure for the vehicle. Each second drive chain 324 is engaged with the two second drive sprockets 323 at both ends of each vertical plate 3221. The two engaged second drive chains 324 are located between the two vertical plates 3221, and the ends of the second drive chains 324 engaged with the second drive sprockets 323 are located outside the ends of the support frame 322. Pins 321 connect between two second drive chains 324. In this embodiment, there are multiple pins 321 connecting the second drive chains 324, and these multiple pins 321 are spaced apart. The output shaft of the transverse drive motor 310 drives the second drive sprockets 323 on the same side of the two sets of hook assemblies 320 respectively. The connection method can be as follows: two second drive sprockets 323 at the same end of the same support frame 322 are connected by a connecting shaft, and the output shaft of the transverse drive motor 310 is connected to the connecting shaft, so that the four second drive chains 324 can be driven to rotate synchronously.

[0045] The working principle of the vehicle platform lateral movement device for the automated parking garage provided in this embodiment is as follows: Figure 8-10As shown: Taking car removal as an example, after the car-carrying platform 400 moves to the side of the lifting frame 100, the micro-drive motor 210 drives the two first drive sprockets 221 of the two sets of transmission components 220 to rotate. The first drive chain 222 drives the support frame 230 to slide a predetermined distance along the second track 120 towards the car-carrying platform 400 through the connecting block 2232 and then stops. At this time, the end of the second drive chain 324 is located below the side longitudinal beam of the car-carrying platform 400, and the two clamping plates 410 are respectively located between the two second drive chains 324. The transverse drive motor 322 drives the four second drive sprockets 323 on the same side to rotate. The pin 321 rotates with the second drive chain 324 to the end of the second drive chain 324 and is inserted into the groove 411 of the clamping plate 410 during the arc rotation from bottom to top. As the transverse drive motor 322 drives the second drive chain 324 to continue rotating, the vehicle carrier 400, driven by the pin 321, slides from the side of the lifting frame 100 onto the first tracks 110 at both ends, eventually moving to a predetermined position on the lifting frame 100. After the vehicle on the vehicle carrier 400 leaves, the transverse drive motor 322 reverses and, in conjunction with the micro-advance drive motor 210, drives the vehicle carrier 400 back from the first track 110 to the frame on the side of the lifting frame 100 via the pin 321. This application achieves lateral displacement by using a micro-advancing mechanism in conjunction with a lateral movement mechanism. In the tracked lateral movement mechanism, the pin shaft mounted between the two drive chains engages with the U-shaped slot during vertical rotation. The arc-shaped movement of the pin shaft at both ends is cleverly utilized to achieve a towing connection with the vehicle platform. Then, the horizontal movement of the pin shaft in the middle section drags the vehicle platform to complete the lateral movement. Through a simple mechanism design, the lateral movement of the vehicle platform can be completed stably, safely, and efficiently. This solves the problems of high power requirements, low lateral movement efficiency, and large space occupation of the rotary mechanism in existing technologies that use a change in horizontal rotational force to horizontal linear drag force for lateral movement. This improves work efficiency and further reduces equipment costs.

[0046] Example 2

[0047] This embodiment 2 is based on embodiment 1. By incorporating a tensioning structure into the hook assembly, the meshing area between the second drive sprocket and the second drive chain is increased, thereby enhancing the stability of the vehicle platform during lateral towing. Specifically:

[0048] like Figure 3As shown, the hook assembly 320 also includes four first tension sprockets 325, each connected to a vertical plate 3221 located near one of the four second drive sprockets 323. These four first tension sprockets 325 engage with the second drive chain 324, transforming the chain, which is initially horizontally aligned, into a trapezoidal shape with no bottom. By increasing the tension of the second drive chain 324 through the first tension sprockets 325, and by positioning them close to the second drive sprockets 323, the meshing area between the second drive chain 324 and the second drive sprockets 323 is effectively increased, improving the stability of the vehicle platform 400 when towed.

[0049] The hook assembly 320 also includes a second tension sprocket 326, a third tension sprocket 327, and an automatic telescopic rod 328. For example... Figure 6 As shown, two automatic telescopic rods 328 are fixedly connected to the two upright plates 3221 of the support frame 322. Two second tension sprockets 326 are connected by a fixed shaft, with both ends of the fixed shaft connected to the two automatic telescopic rods 328. The automatic telescopic rods 328 are self-driven by springs, allowing the second tension sprockets 326 to slide horizontally on the automatic telescopic rods 328 when subjected to external force. A third tension sprocket 327 is mounted below the second tension sprockets 326 via a bracket. The second tension sprocket 326 is externally engaged with the second drive chain 324, while the third tension sprocket 327 is internally engaged with the second drive chain 324. External engagement refers to the sprocket contacting the outer circumferential surface of the chain, while internal engagement refers to the sprocket contacting the inner circumferential surface of the chain. The second drive chain 324 sequentially engages with the second tension sprocket 326, the third tension sprocket 327, and the second drive sprocket 323 located at the end of the support frame 322 to form a U-shaped structure. When the second drive chain 324 is relaxed, the second tension sprocket 326, pulled by the spring on the automatic telescopic rod 328, causes the opening of the U-shaped structure to decrease, thereby tensioning the second drive chain 324. Conversely, when the tension of the second drive chain 324 is greater, the second drive chain 324 drives the second tension sprocket 326 to move outward along the automatic telescopic rod 328, causing the opening of the U-shaped structure to increase and reducing the tension of the second drive chain 324.

[0050] Example 3

[0051] This embodiment 3 is based on embodiment 1 or 2. By adding a turning mechanism for the vehicle platform to turn around, the lateral movement device not only performs the lateral movement function of the vehicle platform but also adds a turning function, effectively expanding the application scenarios of the device. Specifically:

[0052] like Figure 11-14As shown, the slewing mechanism 500 is entirely located within the frame of the lifting stand 100 and also within the frame of the support frame 230. The slewing mechanism 500 mainly includes a lifting drive motor 510, a lifting arm 520, a turntable 530, and a slewing drive motor 540. In this embodiment, the lifting arm 520 has a rack and pinion structure design. The racks of the four lifting arms 520 are respectively connected to the base of the turntable 530. The lifting drive motor 510 drives the racks through the gears of the lifting arms 520, thereby driving the turntable 530 to lift synchronously. A support plate 531 is provided on the top of the turntable 530, which is used to lift the vehicle platform 400 from below. A gear disk 532 with intermeshing transmission is provided inside the turntable 530. The support plate 531 sits on and is connected to the gear disk 532. The slewing drive motor 540 drives the support plate 531 to rotate through the gear disk 532.

[0053] After the vehicle platform 400 is moved onto the lifting frame 100 through the cooperation of the micro-advancing mechanism 200 and the lateral movement mechanism 300, the lifting drive motor 510 drives the four sets of lifting arms 520, so that the support plate 531 lifts the vehicle platform 400 as the turntable 530 rises. When the vehicle platform 400 is lifted to the predetermined height, the rotary drive motor 540 drives the gear disk 532 to rotate. After the support plate 531 rotates 180° with the gear disk 532, the vehicle platform 400 completes the turnaround.

[0054] This application adds a slewing mechanism to enable the vehicle platform to turn around, based on the crawler-type lateral movement mechanism which occupies less space on the lifting frame and provides sufficient structural space for the installation of the mechanism. This adds a slewing function to the lateral movement function of the vehicle platform, effectively expanding the application scenarios of the device.
