Description

Technical Field

[0001] This invention relates to the field of parking equipment technology, specifically to a three-dimensional layered parking system based on a hydraulic tailgate, which is particularly suitable for the three-dimensional transformation of urban ground parking spaces. It can realize two-level three-dimensional parking of passenger cars and two-level multi-vehicle three-dimensional parking of electric motorcycles, and is equipped with an integrated charging solution. It belongs to the field of urban static traffic facilities technology and can be widely used in various ground parking scenarios such as residential areas, shopping malls, office buildings, and streets. Background Technology

[0002] With the acceleration of urbanization, the number of motor vehicles has exploded, and the contradiction between the supply and demand of urban parking resources has become increasingly prominent. "Parking difficulties" have become a major livelihood issue restricting urban development. Existing ground parking spaces all adopt a flat parking method, which has extremely low space utilization. It can only realize the parking of one vehicle per space, and cannot make full use of the space above the parking space, resulting in a serious waste of land resources.

[0003] To address the problem of insufficient parking space, various types of automated parking systems have emerged in the current technology, such as lift-and-slide automated parking systems, vertical circulation automated parking systems, and simple lift-and-slide automated parking systems. However, these automated parking systems generally suffer from the following technical defects: First, the structure is complex, resulting in high manufacturing, installation, and maintenance costs. It also requires a large centralized space, making it unsuitable for the renovation of existing scattered ground parking spaces in cities. Secondly, the problem of mutual interference between vehicles is prominent. The lifting and lateral movement of most multi-level parking garages will affect the parking and retrieval of vehicles in adjacent parking spaces or on the lower level, reducing the efficiency of vehicle storage and retrieval. Third, the functions are limited. Existing multi-level parking garages are mostly designed for cars and do not take into account the parking needs of electric motorcycles. Electric motorcycles are the main means of short-distance transportation in cities, and their number is huge. The problem of scattered and disorderly parking is even more serious. In addition, there is a lack of supporting charging facilities, and behaviors such as charging with extension cords and illegally pulling electrical wires pose great safety hazards.

[0004] Meanwhile, some simple layered parking devices have emerged in the existing technology, such as simple double-layer car parking racks. However, these devices mostly use fixed support structures, and the storage and retrieval of vehicles on the upper level requires moving the vehicles on the lower level first, which is cumbersome. In addition, there are no special safety limit protection measures, the structure is unstable, and there is a safety risk of vehicles slipping. Parking devices for electric motorcycles are mostly single-layer parking racks without layered design, which cannot improve space utilization and are not integrated with charging functions, thus failing to solve the charging problem of electric vehicles.

[0005] In addition, the drive structure and parking structure of the existing layered parking system are closely integrated. If charging facilities are provided, the movement of the system will cause damage to the charging facilities, making it impossible to achieve coordinated operation of parking and charging.

[0006] In summary, existing parking facilities suffer from technical problems such as low space utilization, complex structure, poor adaptability, mutual interference between parking and retrieval, limited functionality, and insufficient safety protection. They cannot simultaneously meet the needs of multi-level parking and charging for both cars and electric motorcycles. There is an urgent need for a multi-level parking system that is simple in structure, adaptable to the renovation of existing ground parking spaces, allows for vehicle storage and retrieval without interference, provides comprehensive safety protection, and integrates parking and charging. This system would make full use of the space above parking spaces and alleviate the dual pain points of parking and charging difficulties in cities. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a three-dimensional, layered parking system based on a hydraulic tailgate. This system addresses technical problems such as low space utilization of existing parking equipment, interference between vehicles when retrieving them from traditional three-dimensional parking garages, dispersed parking and charging of electric motorcycles, and cumbersome operation and lack of safety protection in simple layered devices. This invention enables double-layered three-dimensional parking for cars and double-layered parking for multiple electric motorcycles, ensuring that the retrieval of vehicles in the upper layer does not affect vehicles in the lower layer. It also includes an integrated independent charging device, enabling coordinated operation of parking and charging. The system has a simple structure, can be directly modified from existing ground parking spaces without large-scale construction, has low manufacturing costs, and features comprehensive safety limit protection measures. It is easy to operate, significantly improves the space utilization of parking spaces, and solves the pain points of parking and charging for both cars and electric motorcycles.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A three-dimensional layered parking system based on a hydraulic tailgate includes a parking space body, a hydraulic drive assembly, a hydraulic tailgate, a limit protection assembly, and a charging assembly. The hydraulic drive assembly includes two hydraulic rods, which are symmetrically fixed to the inner sides of the front and rear of the vehicle corresponding to the parking space body. The hydraulic rods are connected to the hydraulic tailgate and drive the hydraulic tailgate to complete the lifting, hovering and folding actions. The limiting and protective components are installed on the hydraulic tailgate and the parking space body, and are used to limit and prevent the vehicle from rolling away when parked. The charging component is an independent structure, separate from the hydraulic tailgate, and is adapted to the charging needs of vehicles parked in layers on the parking space body. The hydraulic tailgate-based three-dimensional layered parking system enables two-layer three-dimensional parking of cars and two-layer multi-vehicle three-dimensional parking of electric motorcycles, and the storage and retrieval of vehicles in the upper part does not affect vehicles parked in the lower part.

[0009] Furthermore, the hydraulic tailgate has a load-bearing capacity of no less than 3.5 tons, suitable for parking vehicles with dimensions of 5.5 meters in length, 2.1 meters in width, and 2.0 meters in height.

[0010] Furthermore, the limiting and protective assembly includes baffles on both sides of the hydraulic tailgate, anti-roll-off stops in front of and behind the tailgate, and limiting stops in front of and behind the vehicle corresponding to the lower part of the parking space body; the width of the baffles is 0.4 meters, and the anti-roll-off stops and limiting stops work together to achieve bidirectional limiting of the vehicle.

[0011] Furthermore, the hydraulic tailgate can be folded vertically and stored on the side of the parking space body when no vehicle is parked, without occupying the floor space of the parking space.

[0012] Furthermore, the hydraulic tailgate for parking electric motorcycles is equipped with several independent partitions, each partition is individually numbered, each partition is 0.7 meters wide, and each partition is suitable for parking one electric motorcycle. The hydraulic tailgate has 3-5 partitions.

[0013] Furthermore, the hydraulic tailgate for four electric motorcycles is 3 meters long and 2 meters wide, while the hydraulic tailgate for five electric motorcycles is 3.8 meters long and 2 meters wide; the lower area of ​​the parking space can simultaneously accommodate the same number of electric motorcycles as the upper partition.

[0014] Furthermore, the charging assembly includes fixed charging plates disposed on the upper, lower and front positions of the parking space body. Each parking space body is equipped with an independent charging device. The position of the charging plate avoids the movement trajectory of the hydraulic tailgate, and the lifting and lowering action of the tailgate does not affect the normal use of the charging plate.

[0015] Furthermore, the power supply for the hydraulic drive component is an external power source. The system adapted to vehicle parking can also be equipped with a solar charging device, forming a dual power supply structure with the external power source.

[0016] Furthermore, the hydraulic telescopic rod for horizontally parked cars is 3.1 meters long, and the hydraulic telescopic rod for vertically parked cars is 5.4 meters long. The extension stroke of the hydraulic rod is matched with the parking method of the vehicle to ensure that the hydraulic tailgate lands on the outer area of ​​the vehicle below.

[0017] Furthermore, the parking spaces for electric motorcycles and the hydraulic tailgates are numbered as a whole by area. The upper parking area is numbered "X Upper N" and the lower parking area is numbered "X Lower N", where X is the overall number of the parking space and N is the sequential number of the partition / lower parking space.

[0018] The hydraulic tailgate-based three-dimensional layered parking system of the present invention overcomes many technical defects of existing parking equipment through the above-mentioned technical solution, and achieves the following significant beneficial effects: 1. Significantly improves the utilization rate of parking space. This invention makes full use of the space above the parking space to realize double-layer three-dimensional parking of cars, doubling the number of cars that can be parked in a single parking space; electric motorcycles can be parked in double layers of 3-5 vehicles per layer, directly doubling the number of electric vehicles that can be parked in a single parking space. This effectively solves the problem of extremely low utilization rate of existing flat parking space, significantly increasing parking capacity without increasing the number of ground parking spaces, and alleviating the contradiction between supply and demand of urban parking resources.

[0019] 2. Achieving Uninterrupted Access to Upper Vehicles: This invention relies on the principle of a hydraulic tailgate, allowing the access of upper vehicles to be completed outside the lower vehicles. The lifting and lowering of the hydraulic tailgate does not contact the lower vehicles, and the parking and driving of upper vehicles do not affect the lower vehicles at all. This solves the technical problem of mutual interference between traditional multi-level parking garages and simple layered devices, improves the efficiency of vehicle access, and is easy to operate.

[0020] 3. Simple structure, adaptable to existing parking space renovation. The core of the system of this invention is a combination of hydraulic rod and hydraulic tail plate. There is no complicated lifting and traversing structure. The manufacturing cost, installation cost and subsequent maintenance cost are far lower than those of traditional three-dimensional parking garages. The system does not need to change the planar dimensions of the existing ground parking space. The renovation can be completed by simply installing hydraulic drive components in the corresponding position. It is adaptable to various scattered ground parking spaces in the city. The renovation compatibility is strong. There is no need for large-scale construction. It can be quickly promoted and applied.

[0021] 4. Comprehensive safety protection measures and high safety in use. This invention is equipped with a full range of limiting protection components, including baffles on both sides of the tailgate, anti-roll-out gears at the front and rear, and limiting bars on the parking space body, to achieve bidirectional limiting of the vehicle in the left and right and front and rear, effectively preventing the vehicle from slipping or rolling during parking and lifting, and ensuring the safety of the vehicle and personnel; at the same time, the load-bearing capacity of the hydraulic tailgate is precisely designed to fully adapt to the weight requirements of conventional cars, and the structure is highly stable.

[0022] 5. Integrating parking and charging to solve charging problems: This invention features an independent charging component. The charging plate is separate from the hydraulic tailgate, and the movement of the tailgate does not affect the use of the charging facilities. Each parking space is equipped with an independent charging device, enabling centralized charging of electric motorcycles and solving the safety hazards of electric vehicles charging by extension cords and haphazard parking. It can also meet the charging needs of new energy vehicles. The car parking system can also be equipped with a solar charging device to achieve an energy-saving and environmentally friendly power supply method, which is in line with the development trend of new energy.

[0023] 6. Clear labeling facilitates vehicle management. Each compartment of the hydraulic tailgate for electric motorcycles in this invention is individually numbered, and the parking space body is numbered by upper and lower area. The standardized numbering rules are used, making the labeling clear and easy for managers to manage vehicles. It also makes it easier for vehicle owners to quickly find their vehicles, thus improving the parking experience.

[0024] 7. Flexible storage without affecting single-layer use of the parking space. The hydraulic tailgate of this invention can be folded vertically and stored on the side of the parking space body when no vehicle is parked, without occupying the floor space of the parking space. This ensures the normal function of the parking space when used in a single layer, realizing flexible switching between three-dimensional parking and single-layer parking to adapt to different parking needs. Attached Figure Description

[0025] Figure 1 This is a schematic diagram of the overall structure of a three-dimensional layered parking system based on a hydraulic tailgate according to the present invention (vehicles parked horizontally, electric motorcycles parked, and vehicles parked vertically). Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] The present invention proposes a three-dimensional layered parking system based on a hydraulic tailgate. The core relies on the lifting principle of the hydraulic tailgate (3) and combines it with structural designs such as limit protection and charging accessories to realize the three-dimensional layered parking of cars and electric motorcycles. The specific technical solution is as follows: The three-dimensional layered parking system based on a hydraulic tailgate of the present invention includes five core parts: parking space body (1), hydraulic drive component, hydraulic tailgate (3), limit protection component and charging component. Each component works together to realize the functions of layered parking, safe storage and retrieval and charging of vehicles. Moreover, the system can be adapted to the specific structural requirements of cars and electric motorcycles.

[0028] Parking space body (1) The parking space body (1) is a basic modification structure for existing ground parking spaces. It does not require changing the original plan dimensions of the parking space. It only requires reserving installation space for hydraulic drive components at the inner positions of the front and rear of the corresponding vehicles. It can be adapted to various standard ground parking spaces in the city, including fixed parking spaces in residential areas, shopping malls, office buildings, etc., and can also be adapted to temporary street parking spaces, with strong modification compatibility. The parking space body (1) is divided into car parking space body (1) and electric motorcycle parking space body (1) according to the type of vehicle to be parked, respectively adapting to the parking needs of cars and electric motorcycles. Among them, the electric motorcycle parking space body (1) can also be divided into four-car type and five-car type according to the number of cars parked on top.

[0029] Hydraulic drive components The hydraulic drive assembly is the core of the system's power, comprising two hydraulic rods (2). The two hydraulic rods (2) are symmetrically fixed to the inner sides of the parking space body (1) corresponding to the front and rear of the vehicle below, and are connected to the hydraulic tailgate (3) for transmission, providing power for the lifting, hovering, and folding movements of the hydraulic tailgate (3). The telescopic rod length of the hydraulic rods (2) is specifically designed according to the parking method of the car: the telescopic rod length of the hydraulic rods (2) adapted to the horizontal parking method is 3.1 meters, and the telescopic rod length of the hydraulic rods (2) adapted to the vertical parking method is 5.4 meters, ensuring that the hydraulic tailgate (3) can be stably placed on the outer area of ​​the vehicle below, avoiding collision with the vehicle below when the tailgate is placed, and ensuring that the vehicle above can drive onto the hydraulic tailgate (3) smoothly. The hydraulic drive components are mainly powered by external power to ensure the stability of power supply. For the car parking system, a solar charging device can also be selected. The solar charging device can be installed on the side or above the parking space body (1) to form a dual power supply structure with the external power supply. It is energy-saving and environmentally friendly and suitable for open-air parking scenarios.

[0030] Hydraulic tailgate (3) The hydraulic tailgate (3) is the core load-bearing structure for realizing layered parking of vehicles. Based on the mature principle of hydraulic tailgate, it can complete the landing, raising, hovering and folding actions under the drive of hydraulic rod (2). Its core function is to support the vehicles parked on the upper part and realize the storage and retrieval of the upper vehicles on the outside of the lower vehicles, ensuring that the storage and retrieval of the upper vehicles does not affect the lower vehicles at all. The hydraulic tailgate (3) is divided into hydraulic tailgate (3) for automobiles and hydraulic tailgate (3) for electric motorcycles according to the parking vehicle type. The structure and size of the two types of tailgates are adapted to the parking needs of the corresponding vehicle types: Hydraulic tailgate (3) for automobiles: Its load-bearing capacity is not less than 3.5 tons, which is fully adapted to the parking needs of conventional automobiles with a body size of 5.5 meters long, 2.1 meters wide and 2.0 meters high; When there are no vehicles parked, the hydraulic tailgate (3) for automobiles can be folded vertically and stored on the side of the parking space body (1), without occupying the planar use space of the parking space, ensuring the normal function of the parking space when used in a single layer. Hydraulic tailgate for electric motorcycles (3): The tailgate is equipped with 3-5 independent partitions (7), each partition (7) is 0.7 meters wide, and each partition (7) is suitable for parking one electric motorcycle. Each partition (7) is assigned a unique number to facilitate vehicle management and retrieval. Depending on the number of vehicles that can be parked on the upper part, the hydraulic tailgate for electric motorcycles (3) is divided into two specifications. The hydraulic tailgate (3) suitable for four electric motorcycles is 3 meters long and 2 meters wide, and the hydraulic tailgate (3) suitable for five electric motorcycles is 3.8 meters long and 2 meters wide. The lower area of ​​the parking space body (1) can simultaneously park the same number of electric motorcycles as the upper partitions (7), thus doubling the number of electric vehicles that can be parked.

[0031] Limit protection components The limiting protection component is set on the hydraulic tailgate (3) and the parking space body (1) to provide all-round safety protection for the parking and lifting of vehicles, and to prevent vehicles from slipping or rolling. It includes three parts: baffle (4), anti-roll gear (5) and limiting bar (6). The baffle (4) is set on both sides of the hydraulic tailgate (3) with a width of 0.4 meters. It is used to limit the left and right displacement of the vehicle on the hydraulic tailgate (3) and prevent the vehicle from slipping off the sides of the hydraulic tailgate (3) during the lifting process. The anti-roll gear (5) is set at the front and rear ends of the hydraulic tailgate (3) to limit the front and rear roll of the vehicle on the hydraulic tailgate (3) and ensure the parking stability of the vehicle on the hydraulic tailgate (3). The limiting bar (6) is set on the parking space body (1) at the front and rear positions corresponding to the lower vehicle. It is used to limit the displacement of the lower vehicle in the parking space body (1) and ensure the parking stability of the lower vehicle. At the same time, it works with the anti-roll gear (5) on the hydraulic tailgate (3) to realize the bidirectional limiting of the layered vehicles.

[0032] Charging components The charging component is a supporting functional structure of the system. It adopts an independent design and is separated from the hydraulic tailgate (3) to realize the coordinated operation of parking and charging, and avoid damage to the charging facilities caused by the movement of the hydraulic tailgate (3). Each parking space body (1) is equipped with an independent charging device (9). The charging component also includes a fixed charging plate (8) fixedly installed on the upper, lower and front positions of the parking space body (1). The installation position of the charging plate (8) avoids the movement trajectory of the hydraulic tailgate (3). The lifting, folding and other movements of the hydraulic tailgate (3) will not affect the normal use of the charging plate (8). The charging component of the electric motorcycle parking space body (1) can realize the centralized charging of electric vehicles and solve the safety hazards of flying wire charging. The charging component of the car parking space body (1) can be adapted to the charging needs of new energy vehicles and can be used with solar charging devices to realize solar charging of new energy vehicles.

[0033] In addition, the parking space body (1) and hydraulic tailgate (3) for electric motorcycles are numbered as a whole by area, using the numbering rules of "X upper N" and "X lower N", where X is the overall number of the parking space and N is the sequential number of the partition (7) / lower parking space. For example, the upper area of ​​the parking space body (1) of seat A is numbered as A upper 1, A upper 2... and the lower area is numbered as A lower 1, A lower 2..., which is clearly marked and facilitates the management and retrieval of vehicles.

[0034] The core principle of the system for vehicle storage and retrieval in this invention is as follows: When a car is parked, the hydraulic rod (2) drives the hydraulic tailgate (3) to land on the outer area of ​​the lower car. After the upper car drives onto the hydraulic tailgate (3), the hydraulic rod (2) drives the hydraulic tailgate (3) to rise and hover in the upper space of the lower car, thus completing the double-layer parking of the car. When the upper car needs to be driven out, the hydraulic rod (2) drives the hydraulic tailgate (3) to fall down and land on the outer side of the lower car, so that the upper car can drive out directly from the hydraulic tailgate (3) without affecting the parking of the lower car. For parking electric motorcycles, the hydraulic rod (2) drives the hydraulic tail plate (3) with partition (7) to land on the outside of the parking space body (1). After the electric vehicles are parked in the independent partition (7) of the hydraulic tail plate (3) in sequence, the hydraulic rod (2) drives the hydraulic tail plate (3) to rise and hover on the upper part of the parking space body (1). The same number of electric vehicles can be parked at the lower part of the parking space body (1) at the same time, completing the double-layer multi-vehicle parking of electric vehicles. The process of taking out electric vehicles is the opposite of the parking process, which is convenient to operate.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The core of the present invention is to provide a three-dimensional layered parking system based on a hydraulic tailgate, which realizes the layered three-dimensional parking of cars and electric motorcycles, where the storage and retrieval of upper vehicles does not affect lower vehicles, and a charging component is provided to integrate parking and charging. To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to specific embodiments. The embodiments are divided into car parking embodiments and electric motorcycle parking embodiments. Each embodiment is based on the core technical solutions of the present invention and is specifically adapted to the parking needs of different vehicle models.

[0036] Example 1: Double-layer multi-level parking system for automobiles This embodiment is a three-dimensional, layered parking system based on a hydraulic tailgate adapted for car parking.

It includes a car parking space body (1), a hydraulic drive assembly, a hydraulic tailgate for cars (3), a limit protection assembly, and a car charging assembly. A solar charging device is also optional. The specific structure and operation process are as follows: Structural design Car parking space body (1): Adopt the standard urban ground car parking space, without changing the original plane size. Only a hydraulic rod (2) installation position is reserved on the inner side of the front and rear of the car body (1).

[0037] Hydraulic drive assembly: includes two hydraulic rods (2) of the same specification, symmetrically fixed at the above-mentioned mounting position. The hydraulic rods (2) are connected to an external power source. At the same time, a solar charging device is installed on the side of the parking space body (1). The solar charging device and the external power source form a dual power supply. According to the parking method of the car, the hydraulic rods (2) are divided into two specifications. The length of the hydraulic rod (2) for horizontal parking is 3.1 meters, and the length of the hydraulic rod (2) for vertical parking is 5.4 meters. The extension stroke of the extension rod is adjustable, and the maximum stroke is consistent with the length of the extension rod.

[0038] Hydraulic tailgate (3) for automobiles: The planar dimensions of the hydraulic tailgate (3) are adapted to the body size of the automobile, with a length of 5.6 meters and a width of 2.2 meters, which is slightly larger than the body size of the automobile, ensuring that the automobile can be parked smoothly; the load-bearing capacity of the hydraulic tailgate (3) is designed to be 4 tons, which is higher than the maximum weight of the automobile of 3.5 tons, ensuring structural stability; the hydraulic tailgate (3) adopts a foldable vertical structure, and the thickness after folding is 0.2 meters, which can be stored on the right side of the parking space body (1) without occupying the planar space of the parking space body (1).

[0039] Limiting and protective components: 0.4-meter-wide metal baffles (4) are set on both sides of the hydraulic tailgate (3). The baffles (4) are welded to the hydraulic tailgate (3) and have high strength. Two anti-slip positions (5) are set at the front and rear ends of the hydraulic tailgate (3). The anti-slip positions (5) are liftable structures. They are raised after the vehicle stops to prevent the vehicle from sliding. A movable limiting bar (6) is set at the front and rear ends of the parking space body (1) corresponding to the lower vehicle. The limiting bar (6) is lowered after the vehicle is parked to limit the displacement of the lower vehicle.

[0040] Car charging components: Each car parking space body (1) is equipped with an independent new energy vehicle charging device (9). The charging device (9) is installed on the rear side of the parking space body (1). A fixed charging plate (8) is set at the upper hovering position, the lower parking position and the front position of the car body (1). The charging plate (8) is connected to the charging device (9) through wires. The installation position of the charging plate (8) avoids the movement trajectory of the hydraulic tail plate (3). The hydraulic tail plate (3) will not touch the charging plate (8) when it is raised or lowered.

[0041] Operating procedures (1) Double-layer parking process ① Lower car parking: Drive the lower car into the car parking space body (1), and after stopping, lower the limit bars (6) in front and behind the parking space body (1) to restrict the displacement of the lower car; ② Tailgate landing: Start the hydraulic drive assembly, the hydraulic rod (2) drives the hydraulic tailgate (3) to unfold outward and slowly land until the hydraulic tailgate (3) is level with the ground. The landing position of the hydraulic tailgate (3) is the right outer side of the lower car, and the distance between it and the lower car is 0.5 meters to avoid collision with the lower car; ③ Upper car parking: Drive the upper car onto the hydraulic tailgate (3), and after stopping, raise the anti-roll gears (5) in front and behind the hydraulic tailgate (3) to restrict the displacement of the upper car; ④ Tailgate suspension: The hydraulic rod (2) drives the hydraulic tailgate (3) to slowly rise until the hydraulic tailgate (3) rises to the upper space of the lower car. The suspension height is 2.2 meters, which is 2.0 meters higher than the height of the car. Meters, to avoid the hydraulic tailgate (3) from contacting the car below, to complete the double-layer three-dimensional parking of the car.

[0042] (2) Upper vehicle removal process ① Tailgate lowering: Start the hydraulic drive assembly, the hydraulic rod (2) drives the suspended hydraulic tailgate (3) to slowly lower until the hydraulic tailgate (3) is level with the ground and lands on the right side of the lower vehicle; ② Vehicle removal: Open the anti-roll gear (5) before and after the hydraulic tailgate (3) and drive the upper vehicle directly out of the hydraulic tailgate (3); ③ Tailgate storage: If there is no need to continue parking the upper vehicle, the hydraulic rod (2) drives the hydraulic tailgate (3) to fold vertically and store it on the right side of the parking space body (1) to complete the removal process.

[0043] (3) Single-layer usage process If only a single-layer parking space is needed, drive the car directly into the car parking space body (1), and after stopping, lower the limit stop bar (6). At this time, the hydraulic tailgate (3) remains in a folded and stored state, which does not affect the normal parking and retrieval of the car.

[0044] (4) Charging process: Whether it is the lower car or the upper car, after the car stops, it can be charged by connecting the charging device (9) through the corresponding fixed charging plate (8). During the charging process, the hydraulic tail plate (3) remains stationary. After the charging is completed, the connection of the charging plate (8) can be disconnected. The subsequent movement of the hydraulic tail plate (3) will not affect the structure and use of the charging plate (8).

It is a preferred embodiment of the electric motorcycle parking system, including an electric motorcycle parking space body (1), a hydraulic drive assembly, a hydraulic tailgate for five-space electric motorcycles (3), a limit protection assembly, and an electric vehicle charging assembly. The specific structure and operation process are as follows: Structural design Electric motorcycle parking space body (1): adopts the urban standard ground non-motorized vehicle parking space, with a plane size of 4 meters long and 2.2 meters wide, which can accommodate the single-layer parking needs of five electric motorcycles.

[0046] Hydraulic drive assembly: includes two hydraulic rods (2), which are symmetrically fixed to the inner side of the parking space body (1) corresponding to the front and rear of the electric vehicle below. The hydraulic rods (2) are only connected to an external power source. The telescopic rod is 2.0 meters long and can drive the hydraulic tail plate (3) to land on the outer area of ​​the parking space body (1). The lifting stroke is 1.8 meters, ensuring that the hydraulic tail plate (3) does not affect the access of the electric vehicle below after it is suspended.

[0047] Hydraulic tailgate (3) for five-car electric motorcycles: The hydraulic tailgate (3) is 3.8 meters long and 2 meters wide, which is compatible with the width of the parking space body (1); Five independent metal partitions (7) are set on the hydraulic tailgate (3), and the partitions (7) are welded to the hydraulic tailgate (3). The width of each partition (7) is 0.7 meters, and the distance between the partitions (7) is 0.05 meters. Each partition (7) is suitable for parking one electric motorcycle; Each partition (7) is assigned a unique number, numbered 1-5. The overall numbering of the hydraulic tailgate (3) is consistent with the numbering of the parking space body (1). For example, the hydraulic tailgate (3) of the parking space body (1) of seat A is numbered A-up 1-A-up 5; The hydraulic tailgate (3) also has a folding and vertical storage function, and can be stored on the side of the parking space body (1) when no vehicle is parked.

[0048] Limiting and protective components: 0.4-meter-wide plastic baffles (4) are set on both sides of the hydraulic tail plate (3), which are lightweight and have a certain protective strength; small anti-slip stops (5) are set at both ends of each partition (7) to prevent electric vehicles from sliding inside the partition (7); the lower area of ​​the parking space body (1) is divided into 5 parking spaces, and each parking space is equipped with a simple limit block to limit the displacement of the electric vehicles below.

[0049] Electric vehicle charging components: Each electric motorcycle parking space body (1) is equipped with an independent electric vehicle charging device (9). The charging device (9) is installed on the side of the parking space body (1). A small fixed charging plate (8) is set in each partition (7) and in each parking space below. The charging plate (8) is connected to the charging device (9). The charging plate (8) adopts a waterproof design to adapt to open-air parking scenarios. The charging plate (8) is fixed to the partition (7) of the hydraulic tail plate (3). When the hydraulic tail plate (3) is raised and lowered, it drives the upper charging plate (8) to move synchronously. The lower charging plate (8) is fixed to the parking space body (1). The upper and lower charging plates (8) do not interfere with each other.

[0050] Operating procedures (1) Double-layer parking process ① Lower electric vehicle parking: Park five electric motorcycles in the five parking spaces at the bottom of the parking space body (1) in sequence, and fix them with limit blocks to complete the lower parking; ② Tailboard landing: Start the hydraulic drive assembly, the hydraulic rod (2) drives the hydraulic tailboard (3) with 5 partitions (7) to unfold outward and land, keeping it horizontal with the ground; ③ Parking of electric vehicles on the upper part: Park the five electric motorcycles in the five independent compartments (7) of the hydraulic tailgate (3) in sequence. After they are parked, raise the anti-slip gear (5) of each compartment (7) and connect the electric vehicles to the charging plate (8) in the compartment (7) for direct charging. ④ Tailgate suspension: The hydraulic rod (2) drives the hydraulic tailgate (3) to slowly rise and hover in the upper space of the parking space body (1). The hovering height is 1.5 meters, ensuring that the electric vehicles below can be stored and retrieved normally, and completing the double-layer three-dimensional parking of five electric motorcycles. At this time, a total of 10 electric motorcycles can be parked in a single parking space body (1), doubling the parking capacity.

[0051] (2) Procedure for removing the upper electric vehicle ① Tailplate lowering: Start the hydraulic drive assembly, and the hydraulic rod (2) drives the hovering hydraulic tailplate (3) to slowly lower until it is level with the ground; ② Remove the vehicle: Disconnect the electric vehicle from the charging plate (8), open the anti-roll gear (5) of the corresponding partition (7), and remove the electric vehicle from the partition (7); ③ Tailgate storage: If there is no need to continue parking the upper electric vehicle, the hydraulic rod (2) drives the hydraulic tailgate (3) to fold vertically and store it on the side of the parking space body (1), completing the retrieval process.

[0052] (3) Charging process: After the electric motorcycle is parked in the partition (7) or the lower parking space, it can be directly connected to the corresponding charging plate (8) for charging. The charging device (9) is independent and can charge a total of 10 electric vehicles in the upper and lower parts at the same time, realizing centralized charging of electric vehicles and solving the safety hazards of flying wire charging. When the hydraulic tail plate (3) is raised and lowered, the upper electric vehicle can maintain the charging state and the charging is not affected by the movement of the hydraulic tail plate (3).

[0053] Example 3: Electric Motorcycle Four-Seat Double-Layer Vertical Parking System This embodiment is a three-dimensional, layered parking system based on a hydraulic tailgate, suitable for parking four electric motorcycles. Its structure and operation process are basically the same as those of Embodiment 2. The core difference lies only in the size of the hydraulic tailgate (3) for electric motorcycles and the number of partitions (7): The hydraulic tailgate (3) in this embodiment is 3 meters long and 2 meters wide. Four independent partitions (7) are set on the hydraulic tailgate (3), each partition (7) is 0.7 meters wide. The lower area of ​​the parking space body (1) can simultaneously park four electric motorcycles, and a single parking space body (1) can park a total of eight electric motorcycles. The partitions (7) of the hydraulic tailgate (3) are numbered 1-4, and the area numbers of the parking space body (1) are "X Upper 1-X Upper 4" and "X Lower 1-X Lower 4". The structure of the hydraulic drive component, limit protection component and charging component in this embodiment is the same as that in Embodiment 2, and the operation process is the same, so it will not be described again here.
