Description

Technical Field

[0001] This utility model relates to the technical field of vertical double-layer parking devices, and in particular to a double-layer parking space system. Background Technology

[0002] Currently, with rapid economic development and accelerating urbanization, private cars (including gasoline-powered vehicles, new energy vehicles, and hybrid vehicles) are increasingly becoming part of households, leading to a growing conflict between car purchase and parking needs. Existing parking spaces are mostly simply marked on the ground, with each space only accommodating one car at a time. This is undoubtedly a waste in cities where land resources are scarce. Existing multi-level parking systems are primarily used in large parking lots, utilizing lift-and-access mechanisms and centralized placement of multiple parking spaces to maximize space utilization. However, these systems suffer from complex structures and high installation and maintenance costs, failing to meet the parking needs of small shopping malls and families with limited budgets.

[0003] Chinese invention patent CN110485770A discloses a double-layer vertical parking device, including a frame, a frame lateral movement system, an upper vehicle platform lifting system, and a lower vehicle platform lateral movement system. The frame is installed at the parking location. The frame lateral movement system and the upper vehicle platform lifting system are mounted on the frame. The lower vehicle platform and the lower vehicle platform lateral movement system are installed at the bottom of the frame. The upper vehicle platform is located inside the frame. The upper vehicle platform lifting system controls the lifting and lowering of the upper vehicle platform. The frame moves laterally under the control of the frame lateral movement system. The upper vehicle platform and the upper vehicle platform lifting system move synchronously with the frame. When the frame moves to a preset travel point, the upper vehicle platform lifting system controls the upper vehicle platform to descend to the bottom of the frame, allowing the car to enter / exit the upper vehicle platform. The upper vehicle platform lifting system then controls the upper vehicle platform to rise to a specified height, and the frame lateral movement system controls the frame to return to its original position. This device enables uninterrupted entry and exit of vehicles in double-layer vertical parking, improving parking efficiency.

[0004] The above solution requires the space of one parking space on the left or right side of a ground parking space in actual operation, which will inevitably affect the adjacent parking spaces (that is, in order to complete the longitudinal parking of 2 cars, the area of ​​3 parking spaces on the ground is required for operation). However, it is impossible to install and work in a space that is only one vehicle width wide. In addition, for the lifting of the vehicle, steel cables are set at the four corners of the upper platform, and the car parked on the upper platform is lifted and lowered through the steel cables. This method of lifting with steel cables will inevitably cause the car to shake during the lifting process. If the initial parking position of the vehicle on the upper platform is not straight, the shaking will be more severe during the lifting process, and there is even a risk of the car shifting.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems of the prior art and provide a double-layer parking space system to solve the technical problems of existing parking devices that use vehicle lateral movement occupying a large amount of vehicle lateral space, and the unstable shaking of vehicles caused by the use of steel wire rope lifting in existing double-layer parking devices, which may even cause vehicles to shift and overturn.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A double-layer parking system includes symmetrically arranged translation tracks on both sides of a ground parking space, and a parking frame capable of horizontal movement relative to the translation tracks. The parking frame includes a vehicle suspension space and a vehicle movement space arranged vertically, with the vehicle movement space corresponding to the position of the ground parking space serving as a vehicle entrance / exit. Symmetrically arranged at the bottom of the parking frame are translation front wheels and translation rear wheels that match the translation tracks. The translation front wheels are adjacent to the vehicle entrance / exit. A translation drive assembly capable of driving the translation front wheels to move horizontally is provided on the parking frame. A vehicle lifting assembly corresponding to the vehicle wheels is also provided on the parking frame, and is driven synchronously to rise and fall by a lifting drive assembly provided on the parking frame.

[0009] Furthermore, the parking frame includes an upper crossbeam and a lower crossbeam arranged parallel to each other above the vehicle entrance / exit. The translation drive assembly includes a translation drive motor and a translation synchronous shaft mounted on the lower crossbeam. The translation synchronous shaft is movably connected to the lower crossbeam via a translation synchronous shaft seat. A translation motor sprocket is mounted on the shaft of the translation drive motor. The translation motor sprocket is connected to the translation motor sprocket mounted on the translation synchronous shaft via a translation motor chain, thereby achieving transmission. Upper translation sprockets are respectively mounted on the left and right ends of the translation synchronous shaft. The upper translation sprockets are connected to the lower translation sprocket on the front translation wheel via a translation chain.

[0010] Furthermore, both the front and rear translation wheels are held by translation roller clamps located at the bottom of the parking frame, and are movably connected to the translation roller clamps via translation roller pins.

[0011] Furthermore, the translation roller pin corresponding to the front translation wheel is also sleeved with the lower translation sprocket after passing through the translation roller clamping seat, and the lower translation sprocket is located in the vehicle's moving space.

[0012] Furthermore, the lifting drive assembly includes a lifting drive motor and a lifting synchronous shaft mounted on the upper crossbeam. A lifting motor sprocket is mounted on the shaft of the lifting drive motor. The lifting motor sprocket is connected to the lifting motor drive sprocket mounted on the lifting synchronous shaft via a lifting motor chain to achieve transmission. The lifting synchronous shaft is movably connected to the lower crossbeam via a lifting synchronous shaft seat. Lifting synchronous sprockets are respectively mounted on the left and right ends of the lifting synchronous shaft. The lifting synchronous sprockets are connected to the vehicle lifting assembly via a first lifting synchronous chain.

[0013] Furthermore, there are four vehicle lifting assemblies, including a first vehicle lifting assembly and a second vehicle lifting assembly located on the left side of the parking frame, and a third vehicle lifting assembly and a fourth vehicle lifting assembly located on the right side of the parking frame; the first vehicle lifting assembly and the second vehicle lifting assembly, as well as the third vehicle lifting assembly and the fourth vehicle lifting assembly, are respectively connected by a second lifting synchronization chain to achieve transmission; the first vehicle lifting assembly is connected to the lifting synchronization sprocket located on the left side through the first lifting synchronization chain to achieve transmission; the third vehicle lifting assembly is connected to the lifting synchronization sprocket located on the right side through the first lifting synchronization chain to achieve transmission.

[0014] Furthermore, the first vehicle lifting assembly, the second vehicle lifting assembly, the third vehicle lifting assembly, and the fourth vehicle lifting assembly all include a lifting upper sprocket support and a lifting lower sprocket support arranged vertically on the parking frame. A lifting upper sprocket is movably connected to the lifting upper sprocket support, and a lifting lower sprocket is movably connected to the lifting lower sprocket support. The lifting upper sprocket and the lifting lower sprocket are connected by a lifting chain to achieve transmission.

[0015] Furthermore, each of the lifting chains is provided with a wheel fork plate, and the horizontal plane formed by each wheel fork plate is horizontal to the ground.

[0016] Furthermore, a roller trolley assembly is symmetrically arranged on the back of the wheel fork plate, and a vertical roller trolley limiting guide rail matching the roller trolley assembly is provided on the parking frame.

[0017] Furthermore, a translation stop block is provided at the rear end of the translation track to limit the translation front wheel.

[0018] This utility model provides a double-layer parking system. It features symmetrically arranged translation tracks on the left and right sides of each ground-level parking space, along with a parking frame capable of horizontal movement relative to these tracks. The horizontal movement of the parking frame is achieved by a translation drive component. Stable lifting and lowering control of the vehicles is achieved through vehicle lifting components corresponding to the four wheels. This system is not only simple in structure and provides excellent vehicle control, but also occupies a small area of ​​ground during operation and can effectively accommodate two vehicles for flexible parking.

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] like Figure 1 and Figure 2 As shown, this solution provides a double-layer parking system, including a translation track 6 symmetrically arranged on both sides of the ground parking space 5, and a parking frame 1 that can move horizontally relative to the translation track 6. The parking frame 1 includes a vehicle suspension space 101 and a vehicle activity space 102 arranged vertically. The position of the vehicle activity space 102 corresponding to the ground parking space 5 serves as the vehicle entrance / exit 103.

[0036] The bottom of the parking frame 1 is symmetrically provided with a front translation wheel 104 and a rear translation wheel 105 that match the translation track 6. The front translation wheel 104 is adjacent to the vehicle entrance / exit 103. The parking frame 1 is provided with a translation drive assembly 2 that can drive the front translation wheel 104 to move horizontally.

[0037] The parking frame 1 is also provided with four vehicle lifting components 4 corresponding to the four wheels 18 of the vehicle 17. The lifting components 3 provided on the parking frame 1 drive the vehicle to lift and lower the vehicle 17 synchronously, so as to raise the vehicle 17 to the vehicle suspension space 101 or lower the vehicle 17 from the vehicle suspension space 101 to the vehicle activity space 102 and make contact with the ground.

[0038] Compared to existing technologies that involve moving the vehicle sideways within a ground-level parking space, this system eliminates the need to occupy space in adjacent parking spaces on either side. Since traditional parking spaces typically have sufficient ground space in front of or behind for vehicles to enter and exit, and this space usually accommodates the vehicle's length requirements, this device meets their installation needs. Furthermore, because this parking frame is designed for double-level parking, it can be used in open-air parking lots or underground garages with a height greater than 3.8 meters.

[0039] like Figure 8 and Figure 9 As shown, the working principle is as follows:

[0040] If the parking frame 1 overlaps with the ground parking space 5 when both the upper and lower levels are empty, then it is only necessary to lower the vehicle fork 411 used to carry the vehicle to the ground in advance, drive vehicle 1 directly onto the four vehicle fork 411, and then directly rise to the hovering space 101; at this time, vehicle 2 can drive directly into the ground parking space 5.

[0041] If all spaces are full, if vehicle number 2 needs to leave, it can simply drive away from ground parking space 5.

[0042] If the parking space is full, and vehicle number 1 needs to leave, the parking frame 1 is moved out of the ground parking space 5 by the translation drive component 2, and then the vehicle lifting component 4 is driven by the lifting drive component 3 to lower vehicle number 1 to the ground and leave.

[0043] Of course, this embodiment only demonstrates some of the parking methods of this system. Depending on the size of the space in front of and behind the ground parking space in the actual environment, other flexible parking methods can also be used.

[0044] As a control method for this system, the translation drive component 2 and the lifting drive component 3 are respectively connected to the electrical control box 11 installed on the parking frame 1 for electronic control; a control box 12 can also be installed at the lower part of the parking frame 1 for convenient manual control by pressing buttons.

[0045] As a cable routing method, a cable support rod 13 can be installed at the end of the ground parking space 5, and a hanging rod 14 can be installed at the top of the cable support rod 13. The cable 15 connected to the electrical control box 11 is supported by several hanging rings 16 that are movably installed on the hanging rod 14.

[0046] like Figure 1 As shown, in this embodiment, the rear end of the translation track 6 is provided with a translation stop block 9, which is used to limit the translation front wheel 104 and prevent it from completely leaving the translation track 104 when it moves directly behind the ground parking space 5.

[0047] In addition, this embodiment can also provide a backstop block 10 on the ground corresponding to the extension end of the translation track 104 to limit the translation rear wheel 105.

[0048] On the other hand, the start and stop control of the translation drive component 2 and the lifting drive component 3 can also be achieved by using proximity switch control. In particular, the signal control method involved in this control method is common knowledge in the field, so it will not be described in detail here.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, the parking frame 1 includes an upper crossbeam 106 and a lower crossbeam 107 arranged parallel to each other above the vehicle entrance / exit 103. The translation drive assembly 2 includes a translation drive motor 201 and a translation synchronous shaft 202 disposed on the lower crossbeam 107. The translation synchronous shaft 202 is movably connected to the lower crossbeam 107 through a translation synchronous shaft seat 203. A translation motor sprocket 204 is disposed on the shaft of the translation drive motor 201. The translation motor sprocket 204 is connected to the translation motor sprocket 206 sleeved on the translation synchronous shaft 202 through a translation motor chain 205 to achieve transmission.

[0050] The left and right ends of the translation synchronous rotating shaft 202 are respectively provided with translation upper sprockets 207. The translation upper sprockets 207 are connected to the translation lower sprockets 209 on the translation front wheel 104 through the translation chain 208, so as to realize the rotation drive of the translation front wheel 104, so that the translation front wheel 104 can move horizontally relative to the translation track 6.

[0051] Specifically, the front translation wheel 104 and the rear translation wheel 105 are both clamped by the translation roller clamping seat 7 located at the bottom of the parking frame 1, and are movably connected to the translation roller clamping seat 7 by the translation roller pin 8.

[0052] The translation roller pin 8 corresponding to the translation front wheel 104 passes through the translation roller clamping seat 7 and is also sleeved with the translation lower sprocket 209, which is located in the vehicle movement space 102. Driven by the translation chain 208, the translation lower sprocket can drive the translation front wheel 104 to rotate, thereby achieving horizontal drive of the parking frame 1.

[0053] In this embodiment, the translational lower sprocket 209 is placed in the vehicle activity space 102, mainly to avoid the impact of collisions with external objects and improve the safety of the device.

[0054] Driven by the translation drive motor 201, the translation front wheel 104 drives the parking frame 1 and the translation rear wheel 105 to move in and out relative to the ground parking space 5. The purpose of moving in is to facilitate overlapping and achieve double-layer parking; the purpose of moving out is to facilitate the vehicle to enter the vehicle suspension space 101 located on the top layer, or to facilitate the vehicle to descend and drive out from the vehicle suspension space 101.

[0055] like Figures 3-5 As shown, the lifting drive assembly 3 includes a lifting drive motor 301 and a lifting synchronous shaft 302 mounted on the upper crossbeam 106. A lifting motor sprocket 303 is mounted on the shaft of the lifting drive motor 301. The lifting motor sprocket 303 is connected to the lifting motor sprocket 305 mounted on the lifting synchronous shaft 302 via a lifting motor chain 304 to achieve transmission.

[0056] The lifting synchronous shaft 302 is movably connected to the lower crossbeam 107 via the lifting synchronous shaft seat 306; the left and right ends of the lifting synchronous shaft 302 are respectively provided with lifting synchronous sprockets 307, and the lifting synchronous sprockets 307 are connected to the vehicle lifting assembly 4 via the first lifting synchronous chain 308 to realize the rotation drive of the vehicle lifting assembly 4, so as to raise the vehicle 17 to the vehicle suspension space 101, or lower the vehicle 17 from the vehicle suspension space 101 to the vehicle activity space 102 and make contact with the ground.

[0057] In this embodiment, there are four vehicle lifting components 4, including a first vehicle lifting component 401 and a second vehicle lifting component 402 disposed on the left side of the parking frame 1, and a third vehicle lifting component 403 and a fourth vehicle lifting component 404 disposed on the right side of the parking frame 1.

[0058] The first vehicle lifting assembly 401 and the second vehicle lifting assembly 402, as well as the third vehicle lifting assembly 403 and the fourth vehicle lifting assembly 404, are respectively connected by a second lifting synchronization chain 405 to achieve transmission.

[0059] The first vehicle lifting assembly 401 is connected to the lifting synchronous sprocket 307 located on the left side through the first lifting synchronous chain 308 to achieve transmission;

[0060] The third vehicle lifting assembly 403 is connected to the lifting synchronous sprocket 307 located on the right side through the first lifting synchronous chain 308 to achieve transmission.

[0061] The first vehicle lifting assembly 401, the second vehicle lifting assembly 402, the third vehicle lifting assembly 403, and the fourth vehicle lifting assembly 404 each include an upper lifting sprocket support 406 and a lower lifting sprocket support 407 vertically disposed on the parking frame 1. An upper lifting sprocket 408 is movably connected to the upper lifting sprocket support 406, and a lower lifting sprocket 409 is movably connected to the lower lifting sprocket support 407. The upper lifting sprocket 408 and the lower lifting sprocket 409 are connected by a lifting chain 410 to achieve transmission.

[0062] It should be noted that the reason why the lifting upper sprocket 408 described in this embodiment can be connected to multiple chains at the same time to achieve synchronous drive is mainly because it is a multi-row gear, such as a three-row gear.

[0063] This embodiment describes the transmission scheme on the left side of the parking frame. The transmission scheme on the right side of the parking frame is similar, as follows:

[0064] The lifting drive motor 301 is started, and the power is transmitted to the lifting synchronous shaft 302 via the lifting motor sprocket 303 and the lifting motor chain 304. The lifting synchronous sprocket 307 located at the left end of the lifting synchronous shaft 302 drives the lifting upper sprocket 408 on the first vehicle lifting assembly 401 to rotate synchronously via the first lifting synchronous chain 308.

[0065] The upper lifting sprocket 408 on the first vehicle lifting assembly 401 drives the upper lifting sprocket 408 on the second vehicle lifting assembly 402 to rotate synchronously via the second lifting synchronous chain 405, and also drives the lower lifting sprocket 409 on the first vehicle lifting assembly 401 to rotate synchronously via the lifting chain 410.

[0066] The upper lifting sprocket 408 of the second vehicle lifting assembly 402 drives the lower lifting sprocket 409 connected to it to rotate synchronously via the lifting chain 410 on it.

[0067] In summary, the lifting drive motor 301 can drive the lifting chains 410 on the first vehicle lifting assembly 401, the second vehicle lifting assembly 402, the third vehicle lifting assembly 403, and the fourth vehicle lifting assembly 404 to rotate synchronously clockwise or counterclockwise.

[0068] like Figure 6 and Figure 7 As shown, each of the lifting chains 410 is provided with a wheel fork plate 411, and the horizontal plane formed by each of the wheel fork plates 411 is horizontal to the ground.

[0069] Specifically, a lifting chain fixing seat 419 is provided on the axis of the back of the wheel fork plate 411. After the lifting chain 410 is wound around the upper lifting sprocket 408 and the lower lifting sprocket 409 respectively, both ends of the chain are fixed to the lifting chain fixing seat 419 by chain locking bolts 420.

[0070] With the above structure, the wheel fork plate 411 can be raised and lowered vertically as the lifting chain 410 rotates clockwise or counterclockwise.

[0071] The back of the wheel fork plate 411 is also symmetrically provided with a roller trolley assembly 412, and a vertical roller trolley limiting guide rail 413 matching the roller trolley assembly 412 is provided on the parking frame 1.

[0072] In this embodiment, the roller trolley assembly 412 includes a pair of roller trolley supports 414 disposed on the back of the wheel fork plate 411. The roller trolley supports 414 are fixedly connected to a plurality of roller connecting seats 416 by bolts 415. Four rollers 417 are movably disposed on the roller connecting seats 416.

[0073] The roller trolley limiting guide rail 413 includes a T-shaped track groove 418 that can be movably embedded in the roller trolley assembly 414. Each roller 417 is limited within the T-shaped track groove 418, and each roller 417 can perform vertical limiting rolling in the T-shaped track groove under the lifting and lowering drive of the wheel fork plate 411.

[0074] Compared to traditional steel wire rope lifting, the structure provided by this solution ensures a more stable lifting process for the vehicle, preventing swaying.

[0075] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
