Description

Technical Field

[0001] This invention belongs to the field of energy storage equipment technology, and in particular relates to a charging vehicle. Background Technology Mobile charging vehicles are important energy supply equipment for emergency power supply, outdoor operations, and special scenarios, and their technological development has attracted much attention.

[0002] Existing mobile charging vehicles typically consist of a frame, energy storage module, control module, and running gear. Their structural design often employs traditional sheet metal welding and modular layouts, resulting in a bulky vehicle with low space utilization. The chassis often uses an independent bridge structure with numerous connecting parts, increasing weight and reducing overall rigidity and stability. Batteries are mostly laid flat or in a single layer, resulting in limited energy density, and heat dissipation usually relies on air cooling or simple ducts, making it difficult to meet the thermal management requirements of high-power charging and discharging conditions. Regarding body protection, existing models mostly use single-layer sheet metal or spliced ​​shells, which are prone to water seepage and dust accumulation at the seams, offering limited waterproof and dustproof ratings, and lacking reliability, especially in harsh environments. Steering control often relies on wireless remote control or mechanical linkages, which suffer from signal delay, low accuracy, and susceptibility to interference, making it difficult to guarantee operational safety and stability.

[0003] Therefore, there is an urgent need for a new type of mobile charging vehicle that is compact, well protected, reliably controlled, and has efficient heat dissipation, in order to solve the problems of wasted space, insufficient protection, poor thermal management, and inconvenient operation in the existing technology. Summary of the Invention

[0004] To address the problems of wasted space, insufficient protection, poor thermal management, and inconvenient operation in existing charging vehicles, this invention proposes a charging vehicle comprising a vehicle frame and a chassis module located at the bottom center of the vehicle frame; suspension modules are provided at the front and rear of the chassis module; the chassis module has a recessed structure in the middle, forming a sunken mounting position; a cooling module is provided within the sunken mounting position. An energy module is installed inside the vehicle frame; a control module is installed on the chassis module; and a vehicle body shell is installed on the outside of the vehicle frame.

[0005] According to the above-described charging vehicle, the chassis module includes a front axle assembly and a rear axle assembly, which are fixedly connected to the vehicle frame by welding. Both the front axle assembly and the rear axle assembly are provided with suspension modules, and each suspension module includes a pad and a spring. The vehicle body shell includes, from top to bottom, an upper body cover, an upper sheet metal, a middle body cover, and a bottom sheet metal; the upper sheet metal has ventilation openings on its side walls; the upper sheet metal has a three-layer structure, and the inner side wall of the upper body cover has a waterproof groove.

The controller is located at the front of the chassis module. The direction control structure includes a handlebar and a belt drive assembly connected to it. The belt drive assembly includes a belt and a sensor, which are connected to each other. The sensor is used to detect the rotation angle of the belt. The sensor is connected to the control module. Turning the handlebar transmits a steering signal through the sensor connected to the belt. The control module controls the steer-by-wire mechanism to achieve steering control. Protective modules are installed on the vehicle frame and energy module, forming an integrated protective structure with the vehicle shell.

[0006] According to the above-described charging vehicle, both the front axle assembly and the rear axle assembly adopt an integral welded structure and are fixedly connected to the vehicle frame through a suspension module to form a stable support structure.

[0007] According to the above-described charging vehicle, the battery storage compartments are stacked sequentially, and each layer of storage compartments has a slide rail at its bottom; friction strips are installed on the slide rails, and the batteries can be pushed in along the slide rails. The friction strips are made of wear-resistant rubber material.

[0008] According to the above-described charging vehicle, the upper sheet metal includes an upper sheet metal, a middle sheet metal, and a lower sheet metal. Each sheet metal layer is sequentially spliced ​​together by a flange structure. The ventilation opening is located on the middle sheet metal and adopts a double-layer mesh design, with the inner layer being a dustproof mesh and the outer layer being a waterproof grille.

[0009] According to the above-described charging vehicle, the upper body cover includes a front cover plate, a middle cover plate, and a rear cover plate, which are connected in sequence by bolts on their inner walls. A water guide groove is provided below the joint where they are connected, and the water guide groove is connected to a waterproof groove.

[0010] According to the above-described charging vehicle, the chassis module's recessed mounting position is located between the front axle assembly and the rear axle assembly; the controller is located on the front axle assembly, and a water-cooled cabinet is also installed in the recessed mounting position, which is fixed by a bracket.

[0011] According to the above-described charging vehicle, the steer-by-wire mechanism includes a steering motor, one end of which is connected to a transmission rod, and the other end of the transmission rod is hinged to a steering linkage. The forward and reverse rotation of the steering motor drives the transmission rod to reciprocate along the axis; the transmission rod drives the steering linkage to swing; thereby causing the steering linkage to drive the wheel hub to perform steering motion.

[0012] According to the above-described charging vehicle, the protection module includes a physical protection layer and an electrical protection layer.

[0014] The beneficial effects of this invention are as follows: 1. Significantly improved space utilization. This invention greatly reduces redundant space by using a welded integrated design of the front and rear axle assemblies, a three-layer battery stacking arrangement, and a recessed installation of the controller and water-cooling cabinet. This allows for more batteries and functional modules to be accommodated within the same volume. Compared to the existing technology's flat battery layout and dispersed arrangement, this design results in a more compact vehicle structure, higher energy density, and longer driving range, making it suitable for space-constrained applications.

[0015] 2. Enhanced overall protective performance. The body shell adopts a multi-layered composite structure, with water-guiding and waterproof channels between the upper body panels and the sheet metal. The sheet metal joints are treated with flanges and seals, and the ventilation openings feature a double-layer design to effectively prevent rainwater and dust intrusion. The protective module integrates physical and electrical protection, working in conjunction with the outer shell to comprehensively improve waterproof, dustproof, impact-resistant, and leakage-proof capabilities, making it suitable for use in harsh environments.

[0016] 3. Significantly improved heat dissipation efficiency. Each battery is equipped with an independent heat sink connected to the water-cooling cabinet, forming a closed-loop liquid cooling module. This precisely controls battery temperature and avoids the localized overheating problems caused by uneven heat dissipation in traditional air-cooling methods. The recessed water-cooling cabinet has a reasonable layout, does not occupy upper space, and improves overall heat dissipation efficiency and battery life.

[0017] 4. Improved control precision and reliability. The steer-by-wire mechanism achieves steering through a steering motor and transmission rod, and combined with physical limit blocks, it prevents oversteering, making operation safer and more stable, and suitable for high-precision operation scenarios.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figures 1 to 9 As shown: This embodiment provides a charging vehicle with a compact structure, excellent protection performance, reliable control, and efficient heat dissipation, suitable for various outdoor and emergency power supply scenarios. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] A charging vehicle according to this embodiment includes a vehicle frame 1, a chassis module 2, an energy module 3, a protection module 4, a vehicle shell 5, and a control module 6.

[0033] The chassis module 2 serves as the support and foundation for the entire vehicle. It includes a front axle assembly 21 and a rear axle assembly 22, both manufactured using an integral welding process to reduce the number of connecting parts and improve structural strength and stability. Both the front axle assembly 21 and the rear axle assembly 22 are fixedly connected to the vehicle frame 1 via a suspension module 23, forming a stable support structure that effectively reduces vibration transmission from the chassis module 2 and improves driving stability.

[0034] The suspension modules 23 on the front axle assembly 21 and the rear axle assembly 22 include pads 231 and springs 232. The pads 231 are made of rubber composite material, and the springs 232 are coil springs, working together to absorb shock and cushion, improving ride stability. A recessed mounting position 25 is located in the center of the chassis module 2 for mounting a water-cooled cabinet. The water-cooled cabinet is fixed by a bracket and connected to the energy module 3 via piping, forming an independent cooling cycle.

[0035] The energy module 3 comprises three layers of batteries stacked from top to bottom inside the vehicle frame 1. The battery storage positions on the vehicle frame 1 are equipped with slide rails 35 and friction strips 34. The friction strips 34 are made of wear-resistant rubber to reduce friction and wear when the batteries are pushed in. The batteries adopt a modular design, allowing them to be pushed into their corresponding positions sequentially from an opening on one side of the vehicle frame 1, making installation convenient.

[0036] Each battery has a heat sink at the bottom, which is connected to a water-cooling cabinet through pipes to form a closed-loop water-cooling module, ensuring that the battery remains within a safe temperature range when working under high load.

[0037] The structure of the vehicle body shell 5 consists of four layers from top to bottom: The top layer is the upper body cover 51, which includes a front cover 511, a middle cover 512 and a rear cover 513. The three are connected by hexagonal bolts. The inner side of the joint is provided with a water guide channel 56 and a waterproof channel 55. Rainwater flows into the water guide channel 56 along the surface of the front cover 511, the middle cover 512 and the rear cover 513, and then is discharged outside the vehicle through the waterproof channel 55, achieving efficient waterproofing.

[0038] The second layer is the upper sheet metal 52, which includes upper sheet metal 522, middle sheet metal 523, and lower sheet metal 524. Each sheet metal piece has a three-layer structure, spliced ​​together by flanges 525, with sealant applied to the joints to further enhance waterproof performance. The middle sheet metal 523 has ventilation openings 521, which adopt a double-layer design: the inner layer is a stainless steel dustproof mesh, and the outer layer is an ABS waterproof grille, which ensures heat dissipation while preventing water and dust intrusion.

[0039] The third layer is the central body panel 53, which is used for connection and sealing between the upper and lower layers. It is made of aluminum alloy profile, which is lightweight and has high strength.

[0040] The bottom layer is the bottom sheet metal 54, which is made up of three different shapes of sheet metal parts. All connection points are located inside the vehicle body, with no exposed screws, making it aesthetically pleasing and providing good protection.

[0041] The control module 6 includes a direction control structure 61, a steer-by-wire mechanism 62, and a controller 63. The controller 63 is mounted on the front axle assembly 21, saving space and facilitating wiring and heat dissipation.

[0042] The steering control structure 61 includes a handlebar 611 and a belt drive assembly 612. When the handlebar 611 is turned, the belt 64 drives the sensor 65 to rotate. The sensor 65 transmits the turning angle signal to the controller 63, and the controller 63 controls the steer-by-wire mechanism 62 to operate according to the signal. The steer-by-wire mechanism 62 includes a steering motor 69, the output end of which is connected to one end of a transmission rod 67. The other end of the transmission rod 67 is hinged to a steering link 66. The forward and reverse rotation of the steering motor 69 drives the transmission rod 67 to reciprocate linearly along the axis. The transmission rod 67 drives the steering link 66 to swing, thereby causing the steering link 66 to drive the wheel hub to make steering movements.

[0043] To limit oversteering of the handlebars 611, a limit block 68 is provided on the transmission path of the belt 64 of the steering control structure 61 to prevent damage to the mechanical structure caused by oversteering of the handlebars 611.

[0044] The protection module 4 includes a physical protection layer and an electrical protection layer. The physical protection layer covers the vehicle body frame and is made of carbon fiber composite material, which has high strength and corrosion resistance. The electrical protection layer is located on the controller 63 and includes leakage protection, short circuit protection, and overload protection modules to ensure electrical safety.

[0045] The protective module 4 and the vehicle body shell 5 form multiple protective barriers, effectively resisting the effects of rain, dust, collisions and electrical faults.

[0046] The electrical connections between the modules of control module 6, as well as between control module 6 and the vehicle frame 1, chassis module 2, and energy module 3, are made via cables and conduits 7. All cables and conduits 7 are neatly arranged using cable trays and fixing clips to avoid wear and compression, thus extending their service life.

[0047] like Figure 11 As shown: The user stands on the foldable pedal 200 and pushes the handlebar 611 to rotate. The signal is transmitted to the controller 63 via the sensor 65. The controller 63 controls the steering motor 69 to operate. The output shaft of the steering motor 69 is connected to the worm gear 72, which meshes with the worm wheel 71. The worm wheel 71 is mounted on the intermediate shaft 70, and the lower end of the intermediate shaft 70 has a gear structure. The transmission rod 67 has a rack structure that meshes with the gear structure. The output shaft of the steering motor 69 drives the worm gear 72 to rotate, and the worm gear 72 meshes with the worm wheel 71, thereby driving the intermediate shaft 70 to rotate. In turn, the gear structure at the lower end of the intermediate shaft 70 and the rack structure of the transmission rod 67 drive the transmission rod 67 to move left and right. The transmission rod 67 drives the steering linkage 66 to swing, thereby causing the steering linkage 66 to drive the wheel hub to make steering motion, realizing the steering of the front wheels. The rear axle assembly 22 is equipped with a drive motor connected to the rear wheel. The controller 63 controls the drive motor to drive the rear wheel to rotate back and forth. The energy module 3 provides power through a three-layer stacked battery, and the water-cooling module continuously dissipates heat to ensure battery safety. The vehicle body shell 5 and the protective module 4 work together to ensure the stable operation of the vehicle in complex environments.

[0048] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
