Description

Technical Field

[0001] This invention relates to the field of mechanical parking equipment technology, specifically an elevated three-dimensional parking unit module suitable for the renovation of old residential areas, integrating photovoltaic power generation, ecological greening and intelligent control functions. Background Technology

[0002] With the acceleration of urbanization, parking difficulties in older residential communities are becoming increasingly prominent. Because early planning did not fully consider the growing demand for motor vehicles, these communities generally suffer from cramped spaces, lack of greenery, and aging infrastructure, making traditional parking solutions ill-suited to their unique environments. The following analysis examines the limitations of existing parking solutions from a technical perspective:

[0003] 1. Problems with traditional multi-level parking garages

[0004] Poor spatial adaptability: Existing multi-level parking garages (such as lift-and-slide type and lane stacking type) require a continuously leveled site (length × width ≥ 20m × 6m), while the distance between buildings in old residential areas is usually less than 10 meters and the shape is irregular, resulting in a low equipment installation rate.

[0005] High energy consumption and high cost: Traditional equipment relies on high-power motors (7.5kW and above) for driving, with an average daily power consumption of 1.2-1.8kWh per parking space, and the amount of steel structure used is as high as 180-220kg / parking space, with a construction cost of about 60,000-80,000 yuan / parking space. In addition, the subsequent maintenance costs make the construction and operation costs high.

[0006] Low ecological compatibility: The construction of multi-story parking garages not only encroaches on the existing activity and green spaces in the community, but also obstructs ventilation and lighting due to the metal structure. In addition, the visual appearance of the garage is also out of place with the community environment.

[0007] Inconvenient vehicle parking: The structure and dimensions of ordinary automated parking garages make it extremely inconvenient for vehicles to enter and exit, easily leading to scratches and seriously affecting safety and user experience. Furthermore, the conventional circular access method in automated parking garages reduces efficiency and is prone to equipment malfunctions.

[0008] 2. Disadvantages of surface parking lots

[0009] Low land utilization rate: Ground parking requires approximately 12-15 square meters per parking space, which leads to the encroachment of a large amount of green space, activity space, and pedestrian space, reducing the quality of the original community environment and failing to meet the requirement of "the green space ratio of old area renovation should not be less than 25%" in the "Urban Residential Area Planning and Design Standard" (GB50180-2018).

[0010] Significant safety hazards: Parked vehicles on the ground obstruct the width of fire lanes, causing obstruction of fire trucks and ambulances in emergencies.

[0011] Poor management: Relying on manual registration or ground lock management, the turnover rate of parking spaces is less than 2 times per day, and disputes occur frequently during peak hours.

[0012] 3. Shortcomings of existing intelligent parking systems

[0013] High energy dependence: Automated parking garages (such as AGV robot parking) require a continuous mains power supply, but the power grid in older residential areas has limited load capacity, and the operation of the equipment is prone to tripping.

[0014] Low modularity: Most existing parking systems use fixed structures, making it impossible to dynamically adjust parking height and number of floors according to the distance between buildings. In addition, installation and splicing between them are not easy.

[0015] Lack of ecological integration: The multi-level parking system has a single function and is not combined with vertical greening, rainwater circulation and other systems, which not only affects the visual image of the community, but also lacks ecological benefits.

[0016] 4. Summary of Technical Pain Points

[0017] The existing technology has the following core defects:

[0018] Poor layout flexibility: It cannot adapt to the current situation of limited land and many irregular spaces in old communities, and large-scale demolition of existing facilities is required during renovation;

[0019] Unsustainable energy: The contradiction between high-energy-consuming equipment and the carrying capacity of the community power grid is prominent;

[0020] Single function: It only solves the parking needs without taking into account the optimization of the community ecology and residents' activity space.

[0021] 5. Market demand and technological gaps

[0022] There are approximately 170,000 old residential communities nationwide that require renovation, with a potential demand for over 50 million parking spaces. However, existing solutions have a compatibility rate of less than 15%. The market urgently needs a solution with the following characteristics:

[0023] Strong spatial adaptability: Small footprint, supports flexible and rapid deployment in irregular sites;

[0024] Energy self-circulation: Photovoltaic systems solve most of the operating energy needs and reduce operating costs;

[0025] Ecological integration: achieving multi-functional integration of parking, greening, and ecological services;

[0026] Ease of use: Vehicles can be parked and retrieved easily and safely, reducing the possibility of scratches.

[0027] Conclusion: Existing technologies, due to structural, energy, and ecological compatibility deficiencies, are insufficient to meet the needs of multi-level parking system renovation in older residential communities. This invention proposes a modular solution for multi-level parking units, which fills the aforementioned technological gaps through elevated structure design, integrated photovoltaic energy storage, and intelligent dynamic control, providing an innovative parking pathway for the renovation of high-density older residential communities. Summary of the Invention

[0028] Purpose of the invention

[0029] This invention provides a modular, three-dimensional parking system that is highly adaptable to different spaces, convenient and safe for parking, has a high energy self-sufficiency rate, and is eco-friendly, thereby increasing the number of parking spaces in the limited space of old residential areas.

[0030] Technical solution

[0031] The three-dimensional parking unit module of the present invention includes:

[0032] Support column assembly: Composed of two sets of steel structure columns, each set further divided into two columns. The lateral spacing (short axis direction) between the two columns is 800-1200mm, and the spacing between the long sides (long axis direction) of the sets is 5100-5400mm, meeting the longitudinal dimension requirements of small motor vehicles. Cable channels and a vertical lifting system (including a brushless motor, Kevlar cables, and gravity balance weights) are installed within the lateral gaps between the two columns. Four vertical sliding rails are installed on the inner sides of the columns to control the vertical movement of the lifting platform system. Installation bases are installed on the left and right sides of the columns starting 3000mm from the ground to connect with the parking unit system, meeting the installation requirements of the parking space. A zigzag or curved structure photovoltaic canopy and battery are installed on the top of the columns to solve the energy supply and roof design issues during vehicle storage and retrieval. The column height is related to the size of the site space, but should be at least 8m to meet the needs of two-level parking.

[0033] Parking unit system: includes parking platform and surrounding vertical green troughs; the parking platform surface is equipped with anti-slip coating and tire limiters, and a PSD position sensor is installed in the middle of the platform to determine the vehicle position and prevent the vehicle from sliding; the parking platform adopts a steel structure and is connected to the steel structure column mounting base by welding or bolts; the short side width of the parking platform is at least 2400mm, and the long side is flush with the long axis of the steel structure column to meet the needs of motor vehicle parking.

[0034] The intelligent lifting platform system includes a lifting platform, a horizontal moving transport platform, a horizontal moving track, and a laser positioning target. The lifting platform is 2100mm wide, and its length is adapted to the long axis of the steel structure column. The horizontal moving transport platform is connected to the lifting platform via a retractable horizontal moving track and can slide left and right. The horizontal moving transport platform has a dynamic lifting function, and hydraulic supports are installed at the connection between the platform and the horizontal moving track. The height of the hydraulic supports can be automatically adjusted according to the height of the parked vehicle chassis (adjustment range 0-200mm). The lifting platform is equipped with an anti-slip coating and tire limiters to prevent vehicle slippage. The vehicle is parked on the side of the steel structure column, with its long side parallel to the long side of the lifting platform. The horizontal moving track moves the horizontal moving transport platform to extend under the vehicle, and then the hydraulic supports rise, allowing the horizontal moving transport platform to lift the steel beam under the vehicle. This transfers the vehicle to the horizontal moving transport platform. The horizontal moving track then moves the transport platform and vehicle back to the lifting platform, and the hydraulic supports lower, thus parking the vehicle on the lifting platform. The lifting platform is driven to reach the height of each parking platform through a vertical lifting system. Similar to the ground-based vehicle transfer, the horizontally moving transport platform extends to the left and right to transport the vehicle to each parking platform.

[0035] Operation and control system: including a lifting control module, installed on the steel structure column, with functions such as storage, retrieval, and stop, to facilitate personnel operation and control of the vehicle's vertical and horizontal coordinated movement; a safety protection module, installed at the top of the space of the steel structure column, to monitor cable tension, structural stress, and wind speed in real time and trigger three-level braking; an energy management module, combined with the battery pack, is located at the top of the space of the steel structure column to control photovoltaic power generation and energy storage; and a lidar module is located at the bottom of the photovoltaic canopy to control the vehicle's positioning on the intelligent lifting platform system.

[0036] Core innovations:

[0037] Modular elevated structure: The elevated structure on both sides reduces the ground space occupied and makes vehicle storage more convenient and safe. In addition, the number of parking layers (2-6 layers) and the combination of modules can be dynamically adjusted according to the size of the site.

[0038] Photovoltaic and energy storage integration: Flexible CIGS batteries generate 18-25kWh of electricity per day, meeting 75% of the equipment's energy consumption needs.

[0039] Low-power lifting system: The counterweight (approximately 0.8 times the vehicle's mass) reduces the motor load, resulting in 40% less energy consumption compared to traditional equipment. Beneficial effects

[0040] Space efficiency: The elevated structure allows each parking space to occupy only 2.5-4.0㎡, saving 80% of space compared to ordinary ground parking spaces.

[0041] Safety in use: When the vehicle is parked, only one side is against the steel structure column, which greatly reduces the risk of scratches. At the same time, the elevated setting allows the ground space to still be used for traffic or activities.

[0042] Ecological benefits: The vertical greening system sequesters 1.2 tons of carbon per unit per year, while also improving the quality of life and visual appeal of the community.

[0043] Economic benefits: Installing a photovoltaic system and adding counterweights to the lifting device greatly reduces electricity consumption. Attached Figure Description

[0054] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the present invention to illustrate the technical principles of the present invention.

[0055] This embodiment provides an elevated, multi-level parking unit module, such as... Figure 1 As shown, it includes a support column assembly 1 (steel structure column 11, double winch lifting system 12, mounting base 13, vertical slide rail 14, frame photovoltaic canopy 15, and battery pack 151).

[0056] The steel structure column 11 consists of two sets of steel structure columns, each set further divided into two columns. Each column is an I-beam, measuring 300x130x13mm, and made of Q345B steel. The lateral spacing (short axis direction) between the two columns is 800-1000mm, and the spacing between the long sides (long axis direction) of the sets is 5100-5400mm, meeting the longitudinal dimension requirements of small motor vehicles. Cable channels and a double winch lifting system 12 are housed within the lateral gaps between the two columns. Four steel vertical slide rails 14 are installed opposite each other on the inner side of the columns to control the vertical movement of the lifting platform system 31 and prevent its lateral swaying. The double winch lifting system 12 (including two brushless motors 121, two Kevlar cables 122, and two gravity balance counterweights 123) is distributed in the gap between the two sets of steel structure columns, primarily for traction driving the vertical lifting intelligent lifting platform system 31. The intelligent lifting platform system 3 (including a lifting platform 31, a horizontal moving transport platform 32, hydraulic supports 321, a horizontal moving track 33, and a laser positioning target 34) primarily functions to transport vehicles horizontally and vertically. The lifting platform 31 measures 5400x2100mm and is a steel frame. The horizontal moving transport platform 32 is connected to the lifting platform 31 via the horizontal moving track 33 and can slide left and right. The horizontal moving transport platform 32 has a dynamic lifting function; a hydraulic support 321 is installed at the connection between the platform and the horizontal moving track, and its height can be automatically adjusted according to the height of the parked vehicle chassis (adjustment range 0-200mm). The lifting platform 32 is equipped with an anti-slip coating 211 and tire limiters 212 to prevent vehicle slippage.

[0057] like Figure 2 As shown, the parking unit system 2 (including parking platform 21, anti-slip coating 211, tire limiter 212, PSD position sensor 22, and vertical greening trough 23) is mainly used for aerial parking. The parking unit system 2 is symmetrically distributed on both sides of the supporting steel structure columns 11 and connected to the mounting base 13 by welding or bolts. The parking platform 21 measures 5400x2400mm, has a steel frame structure, and is equipped with anti-slip coating 211 and tire limiter 212 to prevent vehicles from sliding. The PSD position sensor 22 is located at the center of the parking platform 21, used for sensing whether a parking space is vacant and for vehicle positioning. The vertical greening trough 23 is located around the parking platform 21, with a width of 300mm, for planting greenery. The outer perimeter uses a galvanized steel wire mesh frame or other perforated materials to meet the ventilation and growth needs of the plants.

[0058] like Figure 2 , Figure 3 As shown, parking unit system 2 adopts a two-story layout, accommodating four vehicles. The ground floor has an elevated height of at least 3 meters, and the vertical spacing of parking unit system 2 is at least 2 meters. Brushless motors 121 use 48V DC power, with a single unit load capacity of at least 3 tons. They are installed at both ends of the top of the steel structure columns 11, and both ends are connected to the lifting platform 31 and the counterweight 123 via Kevlar cables 122. The gravity balance counterweight 123 has a mass of 1.2 tons, approximately 0.8 times the mass of a typical vehicle. The frame-type photovoltaic canopy 15 adopts a zigzag or curved surface design, with a steel frame welded to the steel structure columns 11. It is 3.2 meters long, and its upper surface is covered with CIGS solar panels (efficiency 22%), with a peak power of 7.2 kW.

[0059] like Figure 3 , Figure 4 As shown, the lifting control module 41 is installed on the steel structure column 11 and has functions such as storage, retrieval, and stop to facilitate personnel operation; the safety protection module 42 is installed at the top of the column space to monitor cable tension, structural stress, and wind speed in real time and trigger three-level braking; the energy management module 43 is combined with the battery pack 151 to measure the performance of the photovoltaic system and the battery pack; the lidar module 44 is installed below the frame-type photovoltaic canopy 15. The battery pack 151 is installed below the frame-type photovoltaic canopy 15, close to the brushless motor 121, and serves as the main driving energy source. The input of the battery pack 151 is connected to the frame-type photovoltaic canopy 15 and the municipal power supply, and the output is connected to the brushless motor 121; the battery pack 151 is a 48V / 200Ah lithium iron phosphate battery pack with a cycle life of ≥6000 cycles.

[0060] When parking a vehicle, first place the ground vehicle on one side of the long axis of the steel structure column 11, so that the long side of the vehicle is parallel to the long axis of the column. Operate the empty parking space number key in the lifting control module 41, so that the horizontal moving track 33 drives the horizontal moving transport platform 32 to move automatically at a constant speed (0.1m / s), and extends to the lower part of the vehicle. Then the hydraulic support 321 is raised, so that the horizontal moving transport platform 32 can lift the lower steel beam of the vehicle. In this way, the vehicle is transferred to the horizontal moving transport platform 32. The horizontal moving track 33 then drives the transport platform and the vehicle to retract back to the lifting support platform 31. Subsequently, the hydraulic support 321 is lowered, and the vehicle is parked on the lifting support platform 31. The laser radar module 44 and the laser positioning target 34 are combined to measure whether the vehicle position is centered. The laser positioning target 34 and the PSD position sensor (22) on the parking unit system work together to achieve a docking accuracy of ±1mm. The lifting platform 31 is pulled and lifted at a constant speed (0.3m / s) by the double winch lifting system 12 to reach the height of the vacant parking platform 21. Similar to the ground transfer vehicle, the horizontal moving transport platform 32 extends to the left and right through the horizontal moving track 33 to transport the vehicle to the vacant parking platform 21. The left and right travel of the horizontal moving track is 2.5m respectively.

[0061] When retrieving a vehicle, operate the parking space key in the lifting control module 41. The lifting platform 31 will be driven by the double winch lifting system 12 to reach the height of the parking platform 21 where the vehicle is located. The horizontal moving transport platform 32 extends to the left and right through the horizontal moving track 33 to transport the vehicle onto the lifting platform 31. Then the lifting platform 31 will descend to the ground, and the horizontal moving transport platform 32 will lift the vehicle and transport it to one side of the long axis of the steel structure column 11 to complete the vehicle retrieval.
