By utilizing solar power systems to power sightseeing vehicles, zero-emission, low-noise, and sustainable operation can be achieved. Solar-powered sightseeing vehicles have wide application scenarios in urban tourism, scenic spots, and short-distance sightseeing transportation. Compared with traditional fuel-powered sightseeing vehicles, solar-powered sightseeing vehicles have several advantages. First, solar-powered sightseeing vehicles do not produce exhaust emissions, avoiding environmental pollution and improving air quality in tourist areas. Second, solar power systems have long lifespans and low maintenance costs, reducing operating costs, and solar energy resources are widely available, greatly improving the sustainability of sightseeing vehicles.

Solar-powered vehicles are expensive, relying on solar energy, and have limited load-bearing capacity. Furthermore, the installation of solar panels may increase the size and weight of the vehicle. Electric sightseeing vehicles, on the other hand, have limited range, and in some areas, the coverage of charging facilities is inadequate, which can cause inconvenience. In addition, electric sightseeing vehicles have long charging times, limiting the options when fast charging is needed. Utility Model Content

[0035] Please see Figures 1 to 7This utility model provides a sightseeing vehicle structure, including a frame 1, a canopy 2, a front end 3, wheels 4, a seat mechanism 5, and a charging mechanism 6. The frame 1 includes a frame body 11, a battery mounting part 12, a main beam 13, and a U-shaped support part 14. The frame body 11 is fixedly connected to the upper part of the main beam 13.

The drive mechanism 41, a hub-type drive mechanism 41, is suspended inside the frame 1 via a U-shaped support 14; the seat mechanism 5 includes a seat frame 51 and a seat body 52, the seat frame 51 is mounted on top of the frame 1, and multiple sets of seat bodies 52 are provided, with the seat body 52 mounted on top of the seat frame 51; the charging mechanism 6 is electrically connected to the hub-type drive mechanism 41 and the solar panel 22 via wires, and the charging mechanism includes a charging interface 61, a battery compartment 62, and a power battery module 63, the battery compartment 62 is placed in the battery mounting part 12, the power battery module 63 is placed inside the battery compartment 62, and the charging interface 61 is electrically connected to the power battery module 63.

[0036] In this embodiment, the frame 1 refers to a load-bearing frame composed of a frame body 11, a main beam 13, and a U-shaped support 14. The frame body 11 is made of high-strength alloy and welded to the upper part of the main beam 13 to form a main support platform. The two sets of battery mounting parts 12 are rectangular groove structures set at the top of the frame body 11 for fitting the battery compartment 62 assembly. The U-shaped support 14 refers to an arc-shaped suspension mechanism symmetrically distributed at the bottom of the main beam 13, which is connected to the hub-type drive mechanism 41 through elastic bushings to realize the shock absorption function of the wheels 4. The canopy 2 refers to an arc-shaped sunshade structure fixed to the top of the frame 1 by multiple sets of aluminum alloy support columns 21. The solar panels 22 covered on its surface are made of monocrystalline silicon material and are used to convert light energy into electrical energy for storage. The hub-type drive mechanism 41 refers to a brushless motor assembly integrated inside the wheels 4, which realizes power transmission through a planetary gear set. The charging mechanism 6 refers to the energy management system comprising a charging interface 61, a battery compartment 62, and a power battery module 63. The battery compartment 62 is made of fire-retardant material and allows for quick assembly and disassembly via positioning slots in the battery mounting section 12 of the frame 11. The power battery module 63 has a built-in optimized BMS chip and, together with the solar panel 22 and the charging interface 61, forms a dual-channel charging system. This structure achieves optimized spatial integration of the drive system, energy system, and passenger system through modular design.

[0037] In this embodiment, a stable main support platform is formed by welding the high-strength alloy frame 11 of the vehicle frame 1 to the main beam 13. Combined with the elastic bushing suspension design of the U-shaped support part 14, the vehicle body load-bearing strength is ensured while the wheels 4 are damped, improving ride smoothness. The monocrystalline silicon solar panel 22 on the top of the canopy 2, together with the dual charging channels of the charging mechanism 6, can switch between external charging and autonomous solar energy replenishment modes, enhancing the reliability of energy supply. The hub-type drive mechanism 41 optimizes power transmission efficiency and, together with the battery compartment 62, ensures the installation stability of the power battery module 63 and reduces the risk of thermal runaway, achieving a comprehensive effect of compact spatial layout and efficient functional coordination.

[0038] Furthermore, in some embodiments, two sets of support columns 21 are symmetrically distributed on both sides of the front of the vehicle 3, and the remaining support columns 21 are symmetrically distributed on the left and right sides of the frame 1.

[0039] In this embodiment, the support column 21 refers to a column-shaped load-bearing component made of high-strength aluminum alloy, with a hollow rectangular cross-section to balance lightweight and bending resistance, used to evenly transfer the load of the canopy 2 to the main body of the frame 1. The two sets of support columns 21 distributed on both sides of the front of the vehicle 3 are symmetrical column structures vertically installed at the front end of the frame 1. Their bottoms are bolted to the frame 1 via flanges, and their tops are connected to the curved surface of the front edge of the canopy 2. They are used to share the wind resistance impact load and the self-weight of the sunshade structure in the front of the vehicle 3 area. The remaining support columns 21 symmetrically distributed on the left and right sides of the frame 1 are column components arranged at equal intervals along the longitudinal axis of the frame 1. The bottom of each set of support columns 21 is welded to the pre-set mounting base of the main beam 13, and the tops form a continuous support surface with the side of the canopy 2 through an arc transition structure. This is used to maintain the overall shape stability of the canopy 2 and resist lateral torsional stress. The support columns 21 in the front of the vehicle 3 area concentrate the dynamic load of the front, while the support columns 21 on both sides of the frame 1 work together to distribute the static load in the middle and rear. This reduces the amount of material used while ensuring the reliability of the connection between the canopy 2 and the frame 1 and the structural safety under vibration conditions.

[0040] In this embodiment, the support column 21 structure, made of high-strength aluminum alloy and with a hollow rectangular cross-section design, reduces overall weight while improving bending resistance, ensuring efficient transfer of load from the canopy 2 to the frame 1. The support columns 21 on both sides of the front 3 are rigidly connected by flange bolts, with their tops fitting against the curved surface of the front edge of the canopy 2, effectively dispersing wind resistance impact loads and the structural weight of the front 3 area during driving. The support columns 21 on both sides of the frame 1 are welded to the mounting base, with their top curved transition structure forming a continuous support surface with the sides of the canopy 2, collaboratively resisting lateral torsional stress and maintaining the stability of the sunshade structure. The support columns 21 on the front 3 concentrate the dynamic load at the front, while the support columns 21 on both sides of the frame 1 evenly distribute the static load at the middle and rear. Through load path optimization, the structural integrity and long-term reliability of the connection point between the canopy 2 and the frame 1 under vibration conditions are ensured while reducing material consumption.

[0041] Furthermore, in some embodiments, the frame 1 also includes multiple sets of transverse support rods 131, which are fixed to the top of the main beam 13.

[0042] In this embodiment, the transverse support rod 131 refers to a straight rod with a uniform cross-section made of high-strength cold-rolled steel. Preferably, an I-shaped cross-section is used to improve bending and torsional resistance, enhancing the transverse structural stiffness of the top of the main beam 13 and suppressing deformation of the frame 1. The transverse support rod 131 is fixed at equal intervals along the longitudinal axis of the main beam 13 by welding. Preferably, an I-shaped flange forms a continuous load-bearing interface with the upper surface of the main beam 13, effectively dispersing the transverse shear stress generated by the seat mechanism 5 and occupant loads. This design, through the rigid connection between the transverse support rod 131 and the main beam 13, forms a grid-like reinforcing structure, improving the overall torsional stiffness of the frame 1 while providing a reference positioning surface for the installation of the seat frame 51. Its I-shaped cross-section design increases the moment of inertia compared to a traditional rectangular cross-section with the same material usage, satisfying both lightweight requirements and ensuring structural load-bearing efficiency. The surface of the transverse support rod 131 is treated with phosphate spraying, which can inhibit rusting under outdoor conditions and extend the service life of the frame 1.

[0043] In this embodiment, the transverse support rod 131 is made of high-strength cold-rolled steel, which enhances the transverse structural stiffness of the top of the main beam 13 while improving bending and torsional resistance, effectively suppressing the deformation of the frame 1 caused by uneven load distribution. The continuous load-bearing interface formed by its I-shaped flange and the upper surface of the main beam 13 can evenly distribute the transverse shear stress generated by the seat mechanism 5 and the occupant load to the main body of the frame 1. After being fixed at equal intervals along the longitudinal axis of the main beam 13 by welding, it together with the main beam 13 forms a grid-like reinforcing structure, which not only improves the overall torsional stiffness of the frame 1, but also provides a precise reference positioning surface for the installation of the seat frame 51. The I-shaped cross-section design optimizes the moment of inertia of the cross section under the same material usage, taking into account both the goal of lightweighting and the structural load-bearing efficiency requirements. The dense protective layer formed by the surface phosphate spraying treatment can resist the erosion of outdoor moisture and corrosive media, thereby extending the service life of the frame 1 under complex working conditions.

[0044] Furthermore, in some embodiments, the vehicle beam 13 is provided in two sets, the two sets of vehicle beam 13 are arranged in parallel, and the two sets of vehicle beam 13 are connected by multiple sets of transverse support rods 131.

[0045] In this embodiment, the main beam 13 refers to a long, strip-shaped load-bearing component rolled from high-strength alloy steel. Its cross-section has a box-shaped closed structure to improve bending and compressive strength, and it is used to construct the main load-bearing channel of the frame 1 and distribute dynamic loads. The parallel arrangement of the two sets of main beams 13 refers to two main beam structures symmetrically distributed along the longitudinal axis of the frame 1, forming a stable double-track load-bearing foundation. The connection of multiple sets of transverse support rods 131 refers to the use of cold-rolled steel rods vertically welded between the two main beams 13 to form a grid-like reinforcing frame. The I-shaped flange of the transverse support rod 131 forms a continuous force transmission interface with the top surface of the box-shaped cross-section of the main beam 13, which can convert the vertical load applied by the seat mechanism 5 into transverse shear force and uniformly transmit it to the two main beams 13 on both sides, while suppressing the local deformation of the frame 1 under bending and torsional conditions. The parallel double-beam 13 architecture forms a continuous load transfer path in the longitudinal direction through the rigid interconnection of transverse support rods 131, and constructs distributed anti-torsional nodes in the transverse direction, thereby improving the overall rigidity of the frame 1 and reducing the risk of stress concentration. The combined design of its box-section beam 13 and transverse support rods 131 takes into account both material utilization and structural efficiency, and provides a stable installation foundation for the passenger compartment and power system.

[0046] In this embodiment, the parallel double-beam frame 13, through a high-strength alloy steel box-shaped closed section design, significantly improves the bending and compressive resistance of the frame 1, forming a stable dual-track dynamic load transfer channel. The transverse support rod 131, made of I-beam cold-rolled steel, is vertically welded between the two beams 13. Its I-beam flange and the top surface of the beam 13 form a continuous force transmission interface, converting the vertical load of the seat mechanism 5 into a transverse shear force that is evenly distributed to the two beams 13, effectively suppressing local deformation under combined bending and torsion conditions. The mesh layout of the beam 13 and transverse support rod 131, optimized through finite element analysis, establishes a continuous load transfer path in the longitudinal direction while constructing distributed anti-torsion nodes in the transverse direction, reducing the risk of stress concentration and improving the overall stiffness of the frame 1. The combined design of the box-section beam 13 and the I-beam transverse support rod 131 balances material utilization and structural efficiency, providing a stable installation foundation with stronger deformation resistance and better vibration suppression for the passenger compartment and power system.

[0047] Furthermore, in some embodiments, the hub-type drive mechanism 41 includes a drive motor 411 and a reducer, the output shaft of the drive motor 411 being connected to the spokes of the wheel 4 via a flange; the reducer 412 is coaxially arranged with the drive motor 411.

[0048] In this embodiment, the hub-type drive mechanism 41 refers to an integrated power unit inside the wheel 4. Its drive motor 411 is a brushless motor assembly using permanent magnet synchronous technology, with built-in stator windings and rotor magnets, used to convert electrical energy into rotational kinetic energy. The reducer is a planetary gear reducer coaxially mounted with the drive motor 411, which reduces the output shaft speed and amplifies torque through multi-stage gear pairs. The output shaft of the drive motor 411 is a power transmission shaft made of high-strength alloy steel, whose end is rigidly connected to the spokes of the wheel 4 via a flange. The flange is an annular connecting disc with evenly distributed bolt holes, used to achieve high-precision coaxial positioning and torque transmission between the output shaft of the drive motor 411 and the spokes. The spokes are radial support structures connecting the hub and rim at the center of the wheel 4, forged from lightweight aluminum alloy, and receive the rotational power from the output shaft of the drive motor 411 and drive the wheel 4 to rotate via flange bolt groups. The coaxial configuration refers to the design layout in which the input shaft of the reducer, the rotor shaft of the drive motor 411, and the hub shaft of the wheel 4 are aligned. This can eliminate the vibration problem caused by transmission eccentricity. At the same time, the output speed of the drive motor 411 is adjusted in stages through the planetary gear reducer, so that the wheel 4 can obtain a greater driving torque under low-speed conditions and maintain smooth power output under high-speed conditions.

[0049] In this embodiment, the hub-type drive mechanism 41 efficiently converts electrical energy into rotational kinetic energy through a permanent magnet synchronous brushless motor assembly. Its planetary gear reducer uses multi-stage gear pairs to progressively adjust the output shaft speed and torque, enabling the wheel 4 to obtain greater driving torque at low speeds and maintain smooth power output at high speeds. The output shaft of the drive motor 411 is rigidly connected to the lightweight aluminum alloy spokes via a flange. The evenly distributed bolt holes on the flange achieve high-precision coaxial positioning, ensuring no relative displacement occurs during torque transmission. The radial support structure of the spokes evenly transmits rotational power to the rim. Combined with the coaxial layout of the reducer and drive motor 411, this eliminates vibration problems caused by transmission eccentricity. This integrated design confines the power conversion and transmission process within the hub's internal space, reducing mechanical energy loss by shortening the power transmission path. Simultaneously, the multi-stage adjustment function of the planetary gear reducer optimizes power output across a wide speed range, ultimately achieving the dual effects of improved drive efficiency and enhanced operational smoothness.

[0050] Furthermore, in some embodiments, a luggage rack 7 is also included, which is disposed at the rear end of the seat frame 51.

[0051] In this embodiment, the luggage rack 7 refers to a frame-type cargo platform welded from lightweight aluminum alloy profiles. Its main structure adopts a combination design of U-shaped crossbeams and a mesh grille base plate, used to carry passengers' carry-on luggage and travel equipment. The rear end of the seat frame 51 refers to the end area of ​​the seat frame 51 away from the front end 3. The supporting crossbeam refers to the load-bearing component extending laterally along the rear end of the seat frame 51, made of rectangular steel tubing of the same material as the seat frame 51, ensuring connection strength while reducing vibration transmission. The luggage rack 7 adopts an open frame structure. Its U-shaped crossbeams improve bending resistance by increasing the moment of inertia of the section, and the mesh grille base plate provides multi-directional limiting function while reducing its own weight. The modular connection design with the rear end of the seat frame 51 ensures that the luggage rack 7 maintains a safe distance from the passenger seat after installation, and the load is directly transferred to the main structure of the frame 1, avoiding excessive local stress.

[0052] In this embodiment, the luggage rack 7 utilizes a combination structure of a lightweight aluminum alloy U-shaped crossbeam and a mesh grille base plate. This reduces weight while improving bending resistance and enabling multi-directional luggage restraint. The standardized installation interface at the rear of the seat frame 51, after static simulation optimization of layout parameters, is rigidly connected to the supporting crossbeam via bolts, ensuring stable installation of the cargo platform. The supporting crossbeam is made of rectangular steel tubing with a uniformly distributed array of threaded holes on its surface, precisely fitted with fixing clamps. Combined with the pressing and fixing method using rubber buffer pads, it effectively absorbs driving vibration energy while maintaining connection strength. The fixing clamps, through the pre-tightening force applied by the locking bolts, transfer the load of the luggage rack 7 to the main structure of the frame 1 via the supporting crossbeam, preventing localized stress concentration exceeding limits. The modular connection mode of the open frame design ensures a safe distance between the cargo area and the passenger seats, while also achieving efficient dispersion and transmission of cargo loads during driving, ultimately achieving synergistic optimization of luggage storage and transportation functions and vehicle structural safety.

[0053] Furthermore, in some embodiments, the luggage rack 7 includes a horizontal support 71 and a vertical support 72, the horizontal support 71 being fixedly connected to the rear of the seat frame 51; the vertical support 72 being fixedly connected to the horizontal support 71, and the bottom of the vertical support 72 being fixedly connected to the top of the seat frame 51.

[0054] In this embodiment, the flat bracket refers to a U-shaped transverse load-bearing member made of lightweight aluminum alloy profiles, with both ends extending to the rear edges of the seat frame 51. It forms the basic support plane of the luggage rack 7 and distributes the load pressure. The rear of the seat frame 51 refers to the structurally reinforced mounting area at the end of the seat frame 51, which is rigidly connected to the connecting lugs at the bottom of the horizontal bracket 71 using high-strength bolts. The vertical bracket 72 is a column member welded perpendicularly to the horizontal bracket 71. It is made of square tubing of the same material, and its bottom is fixed to the pre-set positioning groove on the upper part of the seat frame 51 via angle brackets. Its top is welded to the side wall of the horizontal bracket 71 to form a three-dimensional frame structure, used to improve the luggage rack 7's anti-tilt capability and constrain load displacement. The fixed connection includes both bolt tightening and welding: the horizontal bracket 71 and the rear of the seat frame 51 are connected by a through-bolt assembly, with spring washers to suppress vibration and loosening; the vertical bracket 72 and the horizontal bracket 71 are permanently joined by continuous fillet welds, and the weld surface is ground to ensure structural smoothness. This dual-support collaborative architecture utilizes the mechanical division of labor, with the horizontal support 71 bearing the main vertical load and the vertical support 72 resisting lateral bending moments, to construct a stable three-dimensional loading platform within a limited space. The U-shaped cross-section design of the horizontal support 71 enhances bending resistance by increasing the moment of inertia, while the square tube structure of the vertical support 72 optimizes torsional stiffness through a four-way symmetrical cross-section. The combination of these two features ensures that the luggage rack 7 maintains geometric stability under dynamic driving conditions, while the load is efficiently transferred to the main body of the frame 1 through the reinforced mounting area at the rear of the seat frame 51.

[0055] In this embodiment, the luggage rack 7 forms a basic support plane through a lightweight aluminum alloy U-shaped cross-section horizontal bracket 71, with both ends extending to the rear edges of the seat frame 51. It is rigidly connected to the structurally reinforced mounting area via high-strength bolts, ensuring even distribution of load pressure. The vertical bracket 72, using a square tube structure, is vertically welded to the horizontal bracket 71. Its bottom is fixed to the upper positioning groove of the seat frame 51 via angle brackets, forming an anti-tilting three-dimensional frame to constrain load displacement. Anti-loosening bolts, combined with spring washers, suppress vibration-induced loosening. Continuous fillet welds are ground to ensure smoothness of the welded area. These two connection methods work together to ensure the structural reliability under dynamic conditions. The U-shaped cross-section of the horizontal bracket 71 enhances bending resistance, while the four-way symmetrical cross-section of the vertical bracket 72 optimizes torsional stiffness. Through mechanical division of labor, they construct a stable three-dimensional load-bearing platform. The reinforced mounting area at the rear of the seat frame 51 efficiently transfers the load to the main body of the frame 1, enabling the luggage rack 7 to possess both geometric stability and dynamic load transmission efficiency within a limited space.

[0056] Furthermore, in some embodiments, the charging interface 61 is located at the front end of the frame 1 near the front end 3.

[0057] In this embodiment, the charging interface 61 refers to a waterproof socket assembly with an IP67 protection rating. Its housing is injection molded from flame-retardant engineering plastic, and copper alloy conductive terminals are embedded inside to establish an electrical connection path between the power battery module 63 and the external charging equipment. The front end of the frame 1 refers to the longitudinal extension of the main body of the frame 1 near the mounting area of ​​the front end 3, which is formed into a mounting platform with reinforcing ribs through a stamping process. The side of the front end 3 refers to the transition area where the outer shell of the front end 3 extends inward to the front end of the frame 1. The sheet metal structure in this area is bent to form a semi-enclosed cavity to accommodate the charging interface 61 and to provide three-sided protection for it.

[0058] In this embodiment, the IP67-rated waterproof socket assembly combines a flame-retardant engineering plastic shell with copper alloy conductive terminals, achieving both flame-retardant insulation and ensuring the stability of the conductive path. The reinforced mounting platform formed by stamping at the front of the frame 1 provides a deformation-resistant support base for the charging interface 61, effectively dispersing installation stress. A semi-enclosed cavity formed by bending sheet metal on one side of the front of the vehicle 3 encloses the charging interface 61 with a three-sided protective structure, preventing direct impact from external objects on the insertion surface and maintaining the structural integrity of the vehicle's transition area. The synergistic cooperation between the flame-retardant shell and the metal enclosure structure ensures charging operation safety while maintaining a compact installation space, forming a multi-layered protection system that provides waterproofing, fireproofing, and protection against mechanical damage.

[0059] Furthermore, in some embodiments, a waterproof cover 611 is also provided on the outside of the charging interface 61.

[0060] In this embodiment, the waterproof cover 611, as an outer protective component, refers to a movable shielding part covering the opening of the charging interface 61. Its base typically adopts a rotating shaft structure or sliding rail structure that matches the housing of the charging interface 61, used to physically shield and isolate external environmental factors. When the cover is closed, it forms a continuous contact surface with the edge of the interface, achieving waterproof function in conjunction with a sealing ring or a sealing structure made of elastic material. The material of the waterproof cover 611 needs to meet the requirements of weather resistance and deformation recovery characteristics. For example, a composite structure of silicone-coated hard plastic can be used to ensure the rigidity of the cover while improving the edge fit. Its opening angle is typically 90° to 120° to balance ease of operation and structural compactness. The limiting protrusion provided on the inner side of the cover can form a positioning fit with the slot on the outer wall of the charging interface 61 to avoid unexpected displacement affecting the sealing effect.

[0061] In this embodiment, the waterproof cover 611 serves as an outer protective component, physically shielding the charging interface 61 through a movable rotating shaft or sliding base, effectively isolating it from external environmental factors such as dust and liquids. When closed, the cover forms a continuous contact surface with the interface edge, and the elastic material sealing structure fills the gaps, ensuring the reliability of the waterproof function. The composite material of silicone-coated rigid plastic maintains the rigidity of the cover structure while continuously improving the edge fit through deformation recovery characteristics, preventing sealing failure after long-term use. The limited opening angle of 90° to 120° ensures both finger movement space during operation and maintains the compactness of the overall device structure. The limiting protrusion on the inner side of the cover forms a positioning fit with the slot on the outer wall of the charging interface 61, generating mechanical restraint in the closed state to prevent cover displacement caused by external impact or vibration, ensuring the integrity of the sealing interface remains intact.
