Description

Technical Field

[0001] This application relates to the field of three-wheeled electric vehicle technology, specifically to a photovoltaic air-conditioned three-wheeled electric vehicle. Background Technology

[0002] The photovoltaic air-conditioned electric tricycle is a new type of transportation that integrates solar power generation, an air conditioning system, and electric drive. It uses monocrystalline silicon photovoltaic panels mounted on the roof to absorb sunlight and convert it into electricity, replenishing the vehicle's battery and reducing reliance on external charging.

[0003] Three-wheeled electric vehicles typically employ a three-wheeled structure design, offering good stability and a certain capacity for carrying goods or passengers. Their power system is primarily electric, but combined with electricity generated by photovoltaic panels, this extends the vehicle's range. The overall design is practical and suitable for short-distance travel, especially in sunny areas where it has significant application value.

[0004] For example, a photovoltaic charging device for a cargo tricycle electric vehicle, authorized by China with publication number CN222147219U, discloses a tricycle electric vehicle that can convert solar energy into electrical energy through a photovoltaic charging panel to drive the electric vehicle normally when the power of the cargo tricycle electric vehicle is insufficient, making the electric vehicle travel more energy-efficient and environmentally friendly.

[0005] However, most photovoltaic air-conditioned tricycles currently on the market do not have good cooling functions for their photovoltaic panels. As a result, when the photovoltaic panels are working, about 80% of the solar energy is converted into heat, which causes the panels to heat up and reduce their power generation efficiency, thus reducing the amount of electricity available to the vehicle. At the same time, the installation of photovoltaic panels and cooling components causes significant obstruction to the airflow when the vehicle is in motion as it passes over the roof. Utility Model Content

[0006] Therefore, this application provides a photovoltaic air-conditioned three-wheeled electric vehicle to solve the problem that existing vehicles do not have good cooling functions, and the installation of photovoltaic panels and cooling components causes significant obstruction to airflow when passing over the roof during vehicle operation.

[0007] To achieve the above objectives, this application provides the following technical solution: A photovoltaic air-conditioning three-wheeled electric vehicle includes a three-wheeled vehicle body, a first fixed guide plate and an installation assembly. A mounting base is fixedly installed on the top of the three-wheeled vehicle body, and a photovoltaic panel is installed on the outside of the mounting base. A first fixed guide plate is fixedly installed on the outer side of the right end of the mounting base, and a movable guide plate is installed on the outer side of the first fixed guide plate through a hinge shaft. A second fixed guide plate is fixedly installed on the outer side of the left end of the mounting base. An installation component is provided on the upper outer side of the first fixed guide plate, and a circulating cooling pipe located directly below the photovoltaic panel is installed inside the installation component. An L-shaped limiting block connected to the first fixed guide plate is fixedly installed on the lower outer side of the installation component. An electric push rod is provided inside the L-shaped limiting block, and the electric push rod is fixedly installed inside the first fixed guide plate. Positioning posts are installed inside both ends of the mounting assembly, and the positioning posts and the electric push rods are arranged in a one-to-one correspondence.

[0008] Furthermore, a mounting frame is welded and fixed to the rear end of the tricycle body, and an air conditioner body is installed inside the right side of the mounting frame.

[0009] Furthermore, the movable guide plate, the first fixed guide plate, and the second fixed guide plate are all provided with prefabricated grooves inside, and the dimensions of the prefabricated grooves are adapted to those of the L-shaped limiting block.

[0010] Furthermore, the mounting assembly includes a connecting plate, a lower fixing plate, and an upper fixing plate. The connecting plate is installed on the outer side of one end of the mounting base near the central axis of the tricycle body, and the lower fixing plate is provided on the outer side of the upper end of the connecting plate. The upper fixing plate is installed on the upper end of the lower fixing plate.

[0011] Furthermore, both sides of the upper fixing plate are provided with first fixing bolts for installation, and the upper fixing plate and the side of the circulating cooling pipe closest to the circulating cooling pipe are in contact with the circulating cooling pipe for fixing the circulating cooling pipe.

[0012] Furthermore, the connecting plate has pre-drilled holes inside, and the positioning pin slides within the connecting plate through the pre-drilled holes.

[0013] Furthermore, a circulating pump connected to a circulating cooling pipe is provided on the top right side of the tricycle body.

[0014] Furthermore, a through groove is provided at the bottom of the middle section of the mounting base to reduce wind resistance.

[0015] Furthermore, the tricycle body has a battery located at the bottom of the seat inside, and a steering control component is installed at the front center of the tricycle body.

[0016] Furthermore, the movable guide plate has a rotation angle of 90°, and a second fixing bolt that is threadedly connected to the photovoltaic panel is provided through the front end of the movable guide plate.

[0017] Compared with the prior art, this application has at least the following beneficial effects: 1. The mounting assembly includes a connecting plate, a lower fixing plate, and an upper fixing plate. The connecting plate is installed on the outer side of one end of the mounting base near the central axis of the tricycle body. The lower fixing plate is provided on the outer side of the upper end of the connecting plate. The upper fixing plate is installed on the upper end of the lower fixing plate. The upper fixing plate has first fixing bolts for installation through both sides. The upper fixing plate and the side of the circulating cooling pipe near the circulating cooling pipe are in contact with the circulating cooling pipe to fix the circulating cooling pipe. This facilitates heat dissipation of the photovoltaic panel through the circulating cooling pipe, preventing the photovoltaic panel from overheating and affecting the power generation effect. 2. The electric push rod is activated by an electrical signal, causing it to extend. At this time, the top of the electric push rod contacts the bottom of the positioning column, generating an upward thrust on the positioning column. This causes the positioning column to slide upward through the pre-made hole in the connecting plate. Under the action of the positioning column, the lower fixing plate can move the circulating cooling pipe and the upper fixing plate upward, thereby reducing the distance between the circulating cooling pipe and the photovoltaic panel and further improving the heat dissipation effect. 3. As the circulating cooling pipe moves upward, it is then housed inside the baffle in the middle of the mounting base. At the same time, a through groove is provided at the bottom of the middle section of the mounting base, allowing the circulating cooling pipe to move upward above the through groove. This avoids affecting the normal ventilation effect of the through groove during driving, thus making the overall installation compact, reducing wind resistance, and ensuring heat dissipation.

Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 6 As shown in the embodiment of this application, a photovoltaic air-conditioned three-wheeled electric vehicle includes: a three-wheeled vehicle body 1, a first fixed guide plate 7, and an installation assembly. An installation frame 2 is welded and fixed to the rear end of the three-wheeled vehicle body 1, and an air conditioning body 3 is installed inside the right side of the installation frame 2. A battery 21 located at the bottom of the seat is provided inside the three-wheeled vehicle body 1, and a direction control assembly 20 is installed in the middle of the front end of the three-wheeled vehicle body 1. An installation seat 4 is fixedly installed on the top of the three-wheeled vehicle body 1, and a photovoltaic panel 5 is installed on the outside of the installation seat 4.

[0023] The photovoltaic panel 5 installed on the top of the tricycle body 1 serves as the main power generation unit, converting solar energy into electrical energy under daytime sunlight. This electrical energy, after being regulated by a DC / DC converter, is preferentially used to replenish the battery 21. When the power generation exceeds the energy storage requirements, the excess electrical energy directly drives the on-board air conditioner 3 to achieve the cooling function. The battery 21, located under the seat, acts as an energy buffer device, storing the redundant power generated by photovoltaic power generation and providing a stable power supply to the drive motor and air conditioning system when sunlight is insufficient.

[0024] The steering control component 20 integrates an electronic power steering module, whose control circuit is connected to the main control system to adjust the power distribution strategy and control the vehicle's direction of travel. The driver can steer flexibly by turning the steering control component 20, utilizing the vehicle's steering system. The entire system collects energy through the photovoltaic panel 5, stores energy through the battery 21, consumes energy through the air conditioning unit 3, and controls the direction of travel through the steering control component 20. All components work together to achieve the energy-saving operation and comfortable driving function of the photovoltaic air-conditioned three-wheeled electric vehicle.

[0025] When the state of charge of battery 21 is detected to be below the threshold, the system automatically switches to economy mode to limit unnecessary load power consumption. Each subsystem interacts with operating data in real time via the CAN bus, forming a closed-loop energy management system. This ensures that the vehicle maintains optimal energy efficiency under different operating conditions. This energy supply path forms a closed-loop system of "photovoltaic power generation - battery energy storage - air conditioning power consumption," reducing the load on battery 21 during driving and significantly improving the vehicle's range and energy self-sufficiency. The working principle of the photovoltaic air-conditioning tricycle is the same as that of a photovoltaic charging device for a cargo tricycle with Chinese authorized publication number CN222147219U. The air conditioning cooling principle is also existing technology and will not be elaborated here.

[0026] Meanwhile, the mounting bases 4 are evenly distributed at the top corners of the photovoltaic panel 5, and the mounting bases 4 have a certain height to install the photovoltaic panel 5, and can ensure that there is a certain gap between the photovoltaic panel 5 and the top of the tricycle body 1 to reduce wind resistance.

[0027] An installation assembly is provided on the outer side of the upper end of the first fixed guide plate 7, and a circulating cooling pipe 10 located directly below the photovoltaic panel 5 is installed inside the installation assembly. The installation assembly includes a connecting plate 8, a lower fixing plate 9, and an upper fixing plate 11. The connecting plate 8 is installed on the outer side of the end of the mounting base 4 near the central axis of the tricycle body 1, and a lower fixing plate 9 is provided on the outer side of the upper end of the connecting plate 8. An upper fixing plate 11 is installed on the upper end of the lower fixing plate 9. First fixing bolts 12 for installation are provided through both sides of the upper fixing plate 11, and the upper fixing plate 11 and the side of the circulating cooling pipe 10 near the circulating cooling pipe 10 are in contact with the circulating cooling pipe 10 to fix the circulating cooling pipe 10, so as to facilitate the heat dissipation of the photovoltaic panel 5 through the circulating cooling pipe 10 and avoid the photovoltaic panel 5 from getting too hot, which would affect the power generation effect.

[0028] Before installation, place the circulating cooling pipe 10 in the groove above the lower fixing plate 9, then cover the circulating cooling pipe 10 with the upper fixing plate 11 and fix it with the first fixing bolt 12.

[0029] A first fixed guide plate 7 is fixedly installed on the outer right side of the mounting base 4, and a movable guide plate 6 is installed on the outer side of the first fixed guide plate 7 via a hinge shaft. A second fixed guide plate 22 is fixedly installed on the outer left side of the mounting base 4. The movable guide plate 6, the first fixed guide plate 7 and the second fixed guide plate 22 are all provided with prefabricated grooves 17. An L-shaped limiting block 15 connected to the first fixed guide plate 7 is fixedly installed on the outer lower end of the mounting assembly, and the dimensions of the prefabricated groove 17 and the L-shaped limiting block 15 are compatible with each other.

[0030] The movable guide plate 6, the first fixed guide plate 7, and the second fixed guide plate 22 all effectively install the L-shaped limiting block 15, facilitating the subsequent installation of the circulating cooling pipe 10 via the connecting plate 8, the lower fixed plate 9, and the upper fixed plate 11, ensuring the circulating cooling pipe 10 is located below the bottom of the photovoltaic panel 5. During installation, the L-shaped limiting block 15 is first inserted into the movable guide plate 6, and then pushed, causing the L-shaped limiting block 15 to move and insert sequentially into the first fixed guide plate 7 and the second fixed guide plate 22. This effectively limits and installs the L-shaped limiting block 15, facilitating the installation of the upper fixed plate 11 below the photovoltaic panel 5 via the L-shaped limiting block 15.

[0031] The movable guide plate 6 has a rotation angle of 90°, and the front end of the movable guide plate 6 is provided with a second fixing bolt 18 that is threadedly connected to the photovoltaic panel 5. After the L-shaped limit block 15 is fully pushed in, the movable guide plate 6 is rotated upward so that the upper end of the movable guide plate 6 rotates to the side wall of the photovoltaic panel 5, and then it is fixed by the second fixing bolt 18.

[0032] Meanwhile, a circulating pump 19 connected to the circulating cooling pipe 10 is installed on the top right side of the tricycle body 1. The two ends of the circulating cooling pipe 10 are then connected to the circulating pump 19 via flanges. During installation, metal flat-welded flanges are aligned and welded to the pipe ends, with sealing gaskets used to ensure no fluid leakage. The circulating pump 19 is a weather-resistant shielded centrifugal pump, with its impeller axis coaxial with the central axis of the cooling circulation pipe to reduce fluid transmission resistance. During operation, starting the circulating pump 19 allows the cooling medium, such as an aqueous ethylene glycol solution, to flow directionally in a closed loop, sequentially passing over the surfaces of high-temperature components for heat exchange before returning to the pump inlet, forming a complete liquid cooling circulation path. The working principles of the circulating cooling pipe 10 and the circulating pump 19 are existing technologies and will not be elaborated upon here.

[0033] The L-shaped limiting block 15 has an internal electric push rod 16, which is fixedly installed inside the first fixed guide plate 7. Positioning posts 13 are installed inside both ends of the mounting assembly, and the positioning posts 13 and the electric push rod 16 are arranged in a one-to-one correspondence. Simultaneously, the second fixed guide plate 22 also has an electric push rod 16 installed inside, with its installation position aligned with the positioning posts 13.

[0034] The connecting plate 8 has pre-drilled holes 14 inside, and the positioning post 13 slides within the connecting plate 8 through the pre-drilled holes 14. The connecting plate 8 serves to install and limit the positioning post 13, allowing the height of the lower fixing plate 9 to be adjusted. After the photovoltaic panel 5, the circulating cooling pipe 10, and the circulating pump 19 are all installed, the electric push rod 16 is activated by an electrical signal, causing the electric push rod 16 to extend. At this time, the top of the electric push rod 16 contacts the bottom of the positioning post 13, generating an upward thrust on the positioning post 13, which in turn drives the positioning post 13 to slide upward within the connecting plate 8 through the pre-drilled holes 14. At this time, the lower fixing plate 9, driven by the positioning post 13, can move the circulating cooling pipe 10 and the upper fixing plate 11 upward, thereby reducing the distance between the circulating cooling pipe 10 and the photovoltaic panel 5 and further improving the heat dissipation effect.

[0035] The electric push rod 16 has a driving voltage of 6V, a stroke of 100mm, and a thrust of 128N. It can be extended when the power is turned on and retracted when the power is reversed.

[0036] As the circulating cooling pipe 10 moves upward, it is then housed inside the baffle in the middle of the mounting base 4. Simultaneously, a through groove is provided at the bottom of the middle section of the mounting base 4, allowing the circulating cooling pipe 10 to move upward above the through groove. This avoids affecting the normal ventilation effect of the through groove during operation, resulting in a compact overall installation that reduces wind resistance and ensures effective heat dissipation.

[0037] Working principle First, place the circulating cooling pipe 10 in the groove above the lower fixing plate 9, then cover the circulating cooling pipe 10 with the upper fixing plate 11 and fix it with the first fixing bolt 12. Then, insert the L-shaped limiting block 15 into the interior of the movable guide plate 6, and then push the L-shaped limiting block 15 so that the L-shaped limiting block 15 moves and inserts into the first fixing guide plate 7 and the second fixing guide plate 22 in sequence, thereby providing a good limiting and installation function for the L-shaped limiting block 15, making it convenient to install the upper fixing plate 11 under the photovoltaic panel 5 through the L-shaped limiting block 15. Then, connect and install the circulating cooling pipe 10 with the circulating pump 19.

[0038] Next, the photovoltaic panel 5 is fixedly installed on the upper outer side of the mounting base 4 with screws, and the movable guide plate 6 is rotated upward so that the upper end of the movable guide plate 6 rotates to the side wall of the photovoltaic panel 5. Then, it is fixed with the second fixing bolt 18, which facilitates the fixing of the positions of the connecting plate 8, the lower fixing plate 9 and the circulating cooling pipe 10.

[0039] The electric push rod 16 is activated by an electrical signal, causing it to extend. At this time, the top of the electric push rod 16 contacts the bottom of the positioning post 13, generating an upward thrust on the positioning post 13. This causes the positioning post 13 to slide upward through the pre-drilled hole 14 within the connecting plate 8. Under the influence of the positioning post 13, the lower fixing plate 9 can move the circulating cooling pipe 10 and the upper fixing plate 11 upward, thereby reducing the distance between the circulating cooling pipe 10 and the photovoltaic panel 5. Simultaneously, the circulating cooling pipe 10 is retracted into the inner side of the baffle in the middle of the mounting base 4, resulting in a compact overall installation.

[0040] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
