Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic power generation system for an electric tricycle. Background Technology

[0002] This design addresses the challenge of providing power for electric tricycles and other electrical appliances in areas with underdeveloped power grids or inconvenient power supply. The primary focus is on agricultural applications: hilly regions often suffer from uneven water resource distribution, and agricultural land lacks sufficient water, requiring water to be pumped from elsewhere. However, the design is also applicable to other tricycle and electrical appliance scenarios. Therefore, this paper presents a photovoltaic power generation system for electric tricycles. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a photovoltaic power generation system for electric tricycles is provided.

[0004] This utility model is achieved through the following solution:

[0005] An electric tricycle photovoltaic power generation system includes an electric tricycle body, the upper part of which is connected to a connecting frame, and the upper part of the connecting frame is connected to a photovoltaic module unit. The photovoltaic module unit includes a middle module fixedly connected to the connecting frame, and an upper module and a lower module connected to the connecting frame via a slide rail mechanism. The upper module can reciprocate above the middle module, and the lower module can reciprocate below the middle module. The middle module, upper module, and lower module all have a structure with foldable photovoltaic panels.

[0006] The front end of the lower component extends above the driver's seat of the electric tricycle body.

[0007] The lower component is connected to the lower slider, and the lower slider is matched with the lower slide rail set on the connecting frame. The lower slider can slide back and forth on the lower slide rail.

[0008] The upper component is connected to the upper slider, and the upper slider is matched with the upper slide rail set on the connecting frame. The upper slider can slide back and forth on the upper slide rail.

[0009] The middle, upper, and lower components are all three-fold photovoltaic panel structures.

[0010] The middle component includes a bottom component flipping mechanism, a middle layer component flipping mechanism, and a top component flipping mechanism. The bottom component flipping mechanism and the middle layer component flipping mechanism are correspondingly hinged through a first hinge member, and the bottom component flipping mechanism and the top component flipping mechanism are correspondingly hinged through a second hinge member.

[0011] Each of the bottom component flipping mechanism, the middle component flipping mechanism, and the top component flipping mechanism is provided with a fixed frame, and each of the fixed frames is provided with a flexible photovoltaic panel.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model discloses a photovoltaic power generation system for an electric tricycle. By setting up sliding and foldable photovoltaic module units, it significantly improves the deployment flexibility and space utilization of photovoltaic panels. The upper and lower modules can slide back and forth along the sliding rail mechanism. The upper, lower, and middle modules all adopt a three-layer folding structure, which allows the photovoltaic panels to be compactly folded up when not in use, reducing the space occupied, and to quickly expand the light-receiving area when needed, adapting to different lighting conditions and energy demands, thereby effectively improving the overall power generation efficiency.

[0014] 2. The lower component extends to the top of the driver's seat, providing not only sunshade for the driver but also balancing the vehicle's load by distributing the weight of the photovoltaic modules between the front and rear axles. This prevents the vehicle from tilting forward or backward due to excessive weight of the upper component, enhancing driving stability and safety. This design balances practicality and structural rationality, achieving multifunctional integration within a limited vehicle space.

[0015] 3. The use of flexible photovoltaic panels combined with a multi-layer flipping mechanism allows the photovoltaic modules to form a continuous, large-area light-receiving surface when unfolded, while the layers of photovoltaic panels fit together for protection when folded, reducing the risk of mechanical damage caused by bumps during transportation. The bending characteristics of the flexible material, combined with the hinged flipping mechanism, ensure that the photovoltaic panels remain flat in the working state, maximizing photoelectric conversion efficiency, while meeting the dual requirements of lightweight and durability for vehicle-mounted equipment.

[0016] 4. The coordinated design of the photovoltaic controller and circuit switch box enables intelligent management of power output. The DC output voltage range covers 36-90V, matching both the standard charging voltage of tricycle batteries and directly driving DC loads such as water pumps. The switching circuit allows for flexible selection between charging and power supply modes. This dual-circuit design enables the system to prioritize power allocation based on actual usage scenarios. For example, it prioritizes water pump operation during irrigation and switches to battery charging during transportation, significantly improving the targeted and practical application of energy utilization.

[0017] 5. The modular design of the sliding rail mechanism allows for independent extension and retraction of the upper and lower modules, enabling users to adjust the unfolded area of ​​the photovoltaic panels according to the size of the parking space or the angle of sunlight. For example, in narrow areas, only the lower modules can be deployed to maintain basic power generation, while in open areas, all modules can be fully deployed to obtain maximum power output. This tiered deployment mode balances environmental adaptability and power generation efficiency, allowing the system to maintain high operating efficiency even in complex terrains such as hilly areas.

[0018] 6. The three-layer folding structure unfolds in tandem through several hinges (first hinge, second hinge). The bottom layer serves as a supporting base, while the middle and top layers flip sequentially to form a stepped layout. This design increases the stacking density of photovoltaic panels within a limited vertical space. Compared to traditional planar paving schemes, this structure achieves three times the actual photovoltaic panel installation area for the same projected area. Especially when the vehicle is stationary, the optimal tilt angle for sunlight absorption can be achieved by adjusting the component angles, significantly improving the power generation output per unit area.

[0019] 7. The entire system adopts a distributed photovoltaic panel layout. The nine flexible photovoltaic panels can work together to increase the total power, and can also be replaced and maintained independently when some are damaged. This design reduces the impact of a single component failure on the overall system. Combined with an independently operable sliding rail mechanism, routine maintenance does not require disassembling the entire photovoltaic array; only specific sliders or rails need to be inspected, greatly improving the maintainability and service life of the system.

[0020] 8. The photovoltaic modules are ergonomically designed for deployment. Operators simply slide the modules in sequence and flip the layers to complete the deployment. To fold them up, simply reverse the process to restore their compact state. This mechanized deployment method avoids complex electrical connections or the need for tools, making it particularly suitable for rural users with limited education. Furthermore, the overall height after folding matches the vehicle's profile, ensuring compliance with traffic regulations regarding vehicle dimensions when driving on roads.

[0021] 9. By deeply integrating the power generation system with transportation vehicles, the functionality of mobile photovoltaic power stations can be expanded. Vehicles can keep the photovoltaic modules folded while transporting agricultural supplies, and quickly deploy them upon arrival at the work site to form a temporary power station, providing continuous power to equipment such as water pumps. This integrated design breaks through the limitations of traditional fixed-installation photovoltaic equipment, making it particularly suitable for building mobile energy nodes in farmland, hilly areas, and other areas without power grids, forming a complete "transportation-power generation-irrigation" operation chain.

[0022] 10. The system adopts a DC bus architecture, with the photovoltaic controller directly outputting DC voltage compatible with the electric vehicle battery pack, eliminating energy losses in the inverter stage. Compared to AC-coupled systems, this design reduces conversion losses by approximately 8-12%, while also reducing circuit complexity and improving system reliability and response speed. Its ability to directly drive DC loads makes it particularly suitable for agricultural irrigation scenarios, avoiding equipment startup delays or efficiency degradation caused by voltage conversion.

Detailed Implementation

[0030] The preferred embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0031] like Figure 1-5As shown, an electric tricycle photovoltaic power generation system includes an electric tricycle body 4. The upper part of the electric tricycle body 4 is connected to a connecting frame 2. The upper part of the connecting frame 2 is connected to a photovoltaic module unit. The photovoltaic module unit includes a middle module 3 fixedly connected to the connecting frame 2. The photovoltaic module unit also includes an upper module 1 and a lower module 5 connected to the connecting frame 2 via a slide rail mechanism. The upper module 1 can slide back and forth above the middle module 3, and the lower module 5 can slide back and forth below the middle module 3. The middle module 3, the upper module 1, and the lower module 5 are all equipped with foldable photovoltaic panels.

[0032] The front end of the lower component 5 extends above the driver's seat of the electric tricycle body 4, which can balance the front and rear weights and also provide a sunshade effect.

[0033] The lower component 5 is connected to the lower slider 6, which in turn matches the lower slide rail 7 mounted on the connecting frame 2. The lower slider 6 can reciprocate on the lower slide rail 7. The upper component 1 is connected to the upper slider 8, which in turn matches the upper slide rail 9 mounted on the connecting frame 2. The upper slider 8 can reciprocate on the upper slide rail 9. The slide rail mechanism can be modularly designed, or commercially available parts can be purchased directly, as long as the reciprocating sliding function can be achieved. Further details are omitted here.

[0034] The middle component 3, upper component 1, and lower component 5 are all three-fold photovoltaic panels (the specific folding principle can be referenced from a well-known three-fold mobile phone).

[0035] The middle component 3 includes a bottom component flipping mechanism 31, a middle layer component flipping mechanism 32, and a top layer component flipping mechanism 33. The bottom component flipping mechanism 31 and the middle layer component flipping mechanism 32 are hinged to each other via a first hinge 34, and the bottom component flipping mechanism 31 and the top layer component flipping mechanism 33 are hinged to each other via a second hinge 35. Each of the bottom component flipping mechanism 31, the middle layer component flipping mechanism 32, and the top layer component flipping mechanism 33 is provided with a fixed frame 36, and a flexible photovoltaic panel 37 is provided within each fixed frame 36. In practical applications, the upper component 1 and the lower component 5 have similar structures to the middle component 3, and will not be described in detail here.

[0036] The photovoltaic power generation system for electric tricycles in this application achieves a balance between high-density power generation and vehicle stability through sliding and foldable multi-layer photovoltaic modules and intelligent power distribution design. It flexibly adapts to the needs of mobile power supply, agricultural irrigation and on-board equipment in hilly areas, while also having the characteristics of quick unfolding and storage and anti-bumping.

[0037] The specific deployment method of the photovoltaic power generation system for an electric tricycle in this application is as follows: Figure 1 , 2 As shown in Figures 3, 4, and 5, Figure 1 This is the fully retracted state of the photovoltaic module of the photovoltaic power generation system for an electric tricycle according to this application, that is, the photovoltaic module unit is not deployed. Figure 2 This indicates that the lower component is extended. Figure 3 This refers to the state where the lower and upper components of a photovoltaic module unit extend simultaneously. Figure 4 The top-level component flipping mechanism of the middle component 3, upper component 1, and lower component 5 is in the open state. Figure 5 The top-layer component flipping mechanism and the middle-layer component flipping mechanism of the middle component 3, upper component 1, and lower component 5 are simultaneously open. When the photovoltaic power generation system for an electric tricycle of this application needs to be folded up, the above steps can be reversed.

[0038] In this embodiment, the middle component 3, upper component 1, and lower component 5 together include nine flexible photovoltaic panels 37. The capacity of the photovoltaic power generation system for an electric tricycle according to this application is 520Wp * 9pcs = 4680Wp. The flexible photovoltaic panels 37 are electrically connected to a photovoltaic controller, whose DC output voltage range is 36-90V. The photovoltaic controller is also electrically connected to a circuit switch box, which can be electrically connected to the DC loads of the tricycle battery and the water pump, respectively. The circuit switch box contains two circuit switches: one controls the charging of the tricycle battery, and the other controls the external DC load. The switch circuit can be switched as needed.

[0039] In practice, more or fewer flexible photovoltaic panels 37 can be set according to the actual situation and customer needs. Their specific electrical parameters and connection relationships with related electrical components are well-known technologies and will not be elaborated here.
