Description

Technical Field

[0001] This invention relates to the field of new energy sightseeing vehicle technology, and in particular to a long-range new energy sightseeing vehicle based on a high-efficiency permanent magnet synchronous motor. Background Technology

[0002] In existing technologies, a common approach to achieve vehicle lightweighting to further improve energy efficiency and driving range is to optimize the chassis structure of sightseeing vehicles. For example, U-shaped steel is used as the main load-bearing component of the chassis, and multiple regularly arranged through holes are made in the web or flange of the U-shaped steel. This design can indeed effectively reduce the chassis's weight and lower the overall vehicle's curb weight, thereby indirectly improving the vehicle's driving range and dynamic response performance.

[0003] However, the existing design concept based on "weight reduction through openings" has a significant limitation: its design goal is too singular, focusing solely on weight reduction. These through-holes in the U-shaped steel are typically treated merely as "hollowed-out areas" for weight reduction, completely ignoring their potential space utilization value. In actual operating scenarios, especially in scenic areas or campuses, passengers (tourists, teachers, and students) often carry backpacks, handbags, small suitcases, photography equipment, and even strollers of varying sizes. These openings in the existing chassis structure are not given any functional purpose and remain idle, failing to provide passengers with flexible and convenient additional cargo space. This leads to: 1. Insufficient storage space: When passengers carry many or large items, the limited space under the seats or in the luggage racks may become insufficient, affecting passenger comfort and potentially obstructing passageways and creating safety hazards. 2. Waste of space resources: The carefully designed holes for weight reduction do not effectively utilize their internal space, essentially wasting structural space resources. 3. Lack of functional flexibility: The chassis structure lacks adaptability to diverse cargo carrying needs and cannot flexibly expand or adjust storage capacity according to actual needs.

[0004] Therefore, an innovative structural design is urgently needed that, while inheriting the advantages of existing "weight reduction through openings," can overcome the limitations of a single function and cleverly transform these weight-reducing openings into usable cargo space, achieving the dual goals of "weight reduction" and "capacity increase." Such a design not only further optimizes the vehicle's energy efficiency but also significantly enhances the practicality of the sightseeing vehicle and passenger comfort, addressing the practical pain point of passengers carrying belongings, thus more comprehensively meeting the operational needs of green sightseeing vehicles. Summary of the Invention

[0005] This invention aims to overcome the problem of limited functionality in the lightweight design of existing new energy sightseeing vehicle chassis. Specifically, it provides an innovative structural design that, while achieving chassis lightweighting, improved energy efficiency, and extended driving range, cleverly transforms these weight reductions into usable cargo space. This leads to the introduction of a long-range new energy sightseeing vehicle based on a high-efficiency permanent magnet synchronous motor, offering enhanced functional expansion capabilities.

[0006] This invention provides a long-range new energy sightseeing vehicle based on a high-efficiency permanent magnet synchronous motor, comprising: a body shell formed by stamping and splicing lightweight aluminum alloy sheets using argon arc welding; a storage compartment shell fixedly connected to the upper part of the body shell and made of the same lightweight aluminum alloy material, wherein a storage compartment is formed inside the storage compartment shell, and a weather-resistant EPDM rubber baffle with a double-layer sealing structure is fixedly connected to the opening edge of the storage compartment shell; and multiple longitudinal and transverse reinforcing ribs penetrating the storage compartment shell and the body shell, the reinforcing ribs being arranged in a grid pattern and connected to the storage compartment shell and the body shell. The inner wall of the body is integrally extruded, and the cross-section of the reinforcing rib is I-shaped or channel-shaped. The inner side wall of the body shell is integrally formed or welded to a recessed large item placement slot for placing large items. The opening edge of the large item placement slot is rotatably connected to a door panel via a stainless steel hinge. The door panel adopts a composite sandwich structure with a rust-resistant steel plate surface and an embedded lightweight high-strength aluminum alloy honeycomb core, and the edge of the door panel is provided with a sealing strip installation groove that cooperates with a rubber baffle. An integrated door lock is installed through the inside of the door panel, and the lock tongue of the integrated door lock cooperates with the corresponding lock hole on the body shell to achieve locking. The key structural components of the vehicle in this invention all adopt high-strength lightweight materials and optimized design, which significantly reduces the overall vehicle weight. For electric vehicles, this directly reduces the energy consumption required for driving and significantly improves the range on a single charge, meeting the core requirement of "long range". In particular, the grid-shaped reinforcing ribs form a highly efficient skeletal structure in key parts of the vehicle body, greatly improving the overall rigidity and strength of the body. This not only enhances the vehicle's driving stability and handling under complex road conditions (such as bumpy roads in scenic areas), but more importantly, it strengthens the body's collision resistance and improves passive safety. It should also be noted that the synergistic effect of the double-layer EPDM rubber baffle and the door panel edge sealing strips forms multiple reliable sealing barriers at the storage compartment opening. This effectively prevents rainwater, dust, mud, and other external pollutants from entering the storage compartment, protecting the cleanliness and dryness of stored items (especially tourists' luggage). The weather-resistant EPDM rubber ensures the durability and sealing effectiveness of the seals under long-term exposure to sunlight, rain, and high and low temperature changes, extending their service life. The honeycomb core structure achieves lightweighting while ensuring door panel rigidity and impact resistance, while the surface rust-resistant steel plate effectively resists environmental corrosion; stainless steel hinges prevent rust jamming and ensure smooth and reliable door opening and closing. It is also worth noting that the use of argon arc welding can provide high-quality, high-strength welded joints, ensuring the robustness and long-term reliability of the connections between the main structural components of the vehicle body (shell, reinforcing ribs), which is crucial to the structural integrity and safety of the entire vehicle. One-piece extrusion molding avoids connection problems and has better overall integrity.
