Description

Technical Field

[0001] This utility model belongs to the field of tracked vehicle technology, specifically relating to a tracked universal driving platform suitable for scientific exploration and engineering operations in complex terrain and other multi-terrain environments. Background Technology

[0002] In complex terrain environments, such as mountains, deserts, and muddy areas, traditional wheeled vehicles often struggle to traverse due to ground limitations. Tracked vehicles, with their superior terrain adaptability, have become a crucial choice for such scenarios. Currently, existing platform vehicles typically employ a rigid, integral frame with a fixed layout for the power battery and control modules, making it difficult to flexibly install functional modules such as cargo platforms, robotic arms, or detection equipment to adapt to different mission requirements. Furthermore, the tracked running gear used in existing tracked platform vehicles lacks an effective shock absorption system, resulting in significant vibrations during high-speed travel or obstacle crossing. This makes them susceptible to direct impact forces, affecting the safety of the transport equipment and impacting the vehicle's durability and operational stability. Utility Model Content

[0003] In view of this, the present invention provides a tracked universal driving platform to solve the problems existing in the prior art.

[0011] The motor reducer assembly is fixedly mounted on the bottom of the front left and right sides of the vehicle frame; the output shaft of the motor reducer assembly is fixedly connected to the drive wheel on the same axis.

[0012] The high-energy-density lithium battery pack is electrically connected to the motor reducer assembly to provide driving power.

[0013] Furthermore, the suspension system includes a spring and shock absorber assembly, suspension arms, and support plates;

[0014] The top end of the suspension arm is rotatably mounted on the vehicle frame, and the bottom end is fixedly connected to the support plate;

[0015] The spring and shock absorber assembly is mounted vertically between the vehicle frame and the support plate;

[0016] The load-bearing wheels are rotatably mounted on the support plate.

[0017] Furthermore, the support plate has an H-shaped structure and includes a crossbeam and longitudinal beams fixedly connected to both ends of the crossbeam;

[0018] The crossbeam is arranged along the width direction of the frame; the longitudinal beam is arranged along the length direction of the frame; and a load-bearing wheel is rotatably installed between the front and rear ends of the two longitudinal beams respectively.

[0019] The bottom end of the suspension arm is fixedly connected to the middle of the crossbeam.

[0020] Furthermore, the suspension arm is a bent structure, comprising an upper inclined arm and a lower vertical arm forming an integral structure; the top end of the inclined arm is rotatably mounted to the vehicle frame; and the bottom end of the vertical arm is fixedly connected to the middle of the crossbeam.

[0028] The vehicle controller is connected to the motor controller and the high-energy-density lithium battery pack, and is responsible for the drive control and high and low voltage power distribution of the vehicle.

[0029] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0030] 1. Existing technologies generally employ integral rigid frames, which are heavy and have limited torsional resistance, resulting in insufficient vehicle stability under complex terrain and high load conditions, and also causing inconvenience in transportation and deployment. This utility model's frame adopts a combination of channel-shaped longitudinal beams and trusses, cleverly achieving a balance between lightweight and high rigidity. The channel-shaped longitudinal beams and trusses not only significantly reduce the overall vehicle weight, making transportation more convenient and improving energy efficiency, but also enhance the frame's durability and stability under high load conditions, maintaining excellent torsional resistance and meeting the needs of high-load and complex terrain operations. Compared to traditional integral rigid frames, the channel-shaped longitudinal beam structure effectively distributes the load, maintaining stability even under rugged terrain or high-intensity load conditions, thus improving overall vehicle durability. Furthermore, this structure provides more layout space inside the vehicle body, allowing for more optimized placement of the power system and electronic control system. The lightweight frame design also makes the vehicle more convenient to transport, meeting the needs of various operational scenarios.

[0031] 2. Addressing the issues of low efficiency and long downtime during function switching and maintenance in existing technologies, this utility model's tracked universal driving platform incorporates a modular design concept in core components such as the chassis, power system, suspension system, and superstructure functional modules. This allows for rapid disassembly and replacement of core components, solving the problems of fixed functions and complex disassembly / reassembly in existing platform vehicles. The modular design enables quick disassembly and assembly of the power battery box, control system, and suspension system, significantly reducing the time and cost of equipment transportation, deployment, and maintenance. Simultaneously, the modular design supports flexible functional expansion in multi-task scenarios, such as the rapid replacement of cargo transport modules, robotic arms, or detection equipment modules to meet complex operational needs. The power battery box adopts a low-position modular layout, optimizing the vehicle's center of gravity distribution and making replacement and maintenance more convenient.

[0032] 3. Existing tracked running mechanisms mostly employ a rigid design, lacking a suspension system or featuring a complex suspension design. This results in poor vehicle stability when traversing rough terrain or high-speed obstacle crossings, with impact forces directly transmitted to the vehicle body, adversely affecting the vehicle's service life and load safety. The tracked running mechanism of this invention, combined with a modular suspension system, enables stable vehicle operation in complex terrains such as rough, muddy, and sloping surfaces. Furthermore, this invention, through its modular independent suspension design, allows the road wheels to be evenly distributed on the bottom of the tracks and flexibly adapts to ground undulations, not only improving the vehicle's passability and traction but also significantly reducing the impact of vibration on the vehicle body. Combined with the tracked running mechanism design, this vehicle can efficiently adapt to various terrains, improving overall operational capability and durability, and enhancing the vehicle's operational stability and passability in complex terrains.

[0033] This invention is applicable to various operational scenarios in complex terrains, such as material transportation, rescue operations, and environmental detection. It has the advantages of reasonable structure, reliable performance, and wide application. Attached Figure Description
