[0002] Currently, the demand for multifunctional tools and vehicles is constantly increasing in industrial and agricultural production, outdoor operations, and other fields. Traditional tools and vehicles have revealed some technical shortcomings. For example, small wheeled agricultural tools, due to their miniaturization, cannot be made too large. However, they often slip or fail to climb steep slopes. Even adding tracks to the wheels of existing wheeled agricultural tools does not solve the problem of not being able to climb slopes due to their small size.

[0003] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an adjustable convertible vehicle, which aims to solve the problem that traditional utility vehicles in the prior art are generally wheel-driven and are prone to slipping and spinning in the air or scraping the chassis when encountering complex terrain such as muddy swamps, steep slopes and gravel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable conversion vehicle includes a vehicle body, a drive assembly located at the bottom of the vehicle body, a dual track wheel assembly located at the output end of the drive assembly, and a cargo assembly located at the front of the vehicle body. The two track wheels of the dual track wheel assembly are arranged parallel to each other in the vertical direction and are connected by a connecting rod. A sensor is also provided at the front end of the drive assembly for detecting the road conditions in front of the vehicle body.

[0007] Furthermore, the dual track wheel assembly includes a large track wheel and a small track wheel. Both the large and small track wheels are located on both sides of the drive assembly, and the large and small track wheels are connected by two connecting rods to form a parallelogram structure. One end of one of the connecting rods passes through the large track wheel and connects to the axle. The axle also has an attitude adjustment motor in the middle, and the attitude adjustment motor is fixed outside the drive assembly.

[0008] Furthermore, the small track wheel is also equipped with a pulley motor.

[0009] Furthermore, the drive assembly includes a drive housing, a drive shaft is provided inside the drive housing, a drive motor is provided on the drive shaft, and the drive shaft passes through both ends of the drive housing and is connected to the drive wheel of the dual track wheel assembly.

[0010] Furthermore, the vehicle body includes a control console and an L-frame. The control console is located at the upper end of the L-frame and has a power supply inside. The control console is connected to the drive assembly and the dual track wheel assembly via wires. A rear wheel is also provided at the corner of the L-frame.

[0011] Furthermore, the conductor is covered with a rubber tube.

[0012] Furthermore, the console is equipped with multiple buttons, including a start button, a lift button, and an emergency stop button.

[0013] Furthermore, the loading assembly includes at least two electric cylinders, a support rod for fixing the electric cylinders to the drive assembly, and a loading component disposed on the output shaft of the electric cylinders.

[0016] The technical solution adopted in this utility model has the following beneficial effects:

[0017] In this invention, the vehicle's wheels are designed as a vertically arranged double-track wheel structure. When the vehicle encounters complex terrain such as uphill sections, the control console is activated. The track wheels are connected via linkages, and sensors on the drive box detect the terrain, transmitting signals to the control console. A posture adjustment motor then moves the linkages, raising the smaller track wheel to the front of the larger track wheel, transforming the overall structure into a triangular track configuration. This provides better power for the vehicle when traveling uphill or on uneven terrain, preventing slippage. Simultaneously, the smaller track wheel is also equipped with a pulley motor, providing further power when climbing slopes. This effectively enhances the vehicle's adaptability to complex terrain, preventing slippage, wheel spin, and chassis scraping, thus significantly improving the efficiency and practicality of transporting materials in complex terrain.

[0027] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] An adjustable conversion vehicle, such as Figure 1 As shown, it includes a vehicle body, a drive assembly located at the bottom of the vehicle body, a dual track wheel assembly located at the output end of the drive assembly, and a cargo assembly located at the front of the vehicle body. The front end of the drive assembly is also equipped with a sensor 5, which is used to detect the road conditions in front of the vehicle body. This utility model first replaces the wheel structure commonly used in existing utility vehicles with a track wheel structure, which can better adapt to complex road terrain and avoid slippage.

[0029] In this embodiment, as Figure 1 , Figure 2 As shown, the dual track wheel assembly includes a large track wheel 1 and a small track wheel 2. Both the large track wheel 1 and the small track wheel 2 are located on both sides of the drive assembly, and the large track wheel 1 and the small track wheel 2 are connected by two connecting rods 3 to form a parallelogram structure. One end of one of the connecting rods 3 passes through the large track wheel 1 and connects to the shaft 29. The shaft 29 is also provided with an attitude adjustment motor 30 in the middle, and the attitude adjustment motor 30 is fixed outside the drive assembly. A pulley motor 16 is also provided on the small track wheel 2.

[0030] The track wheels utilize a common small track wheel structure found in existing technology. The connecting rod 3 is connected to the track wheels via bearings to avoid affecting their movement. The rear connecting rod 3 is connected to the axle 29. When the attitude adjustment motor 30 is activated, it drives the connecting rod 3 to rotate, thereby pushing the small track wheel 2 forward of the large track wheel 1, forming a triangular structure. This structure is more adaptable to sloping or uneven terrain, avoiding obstacles. Furthermore... Figures 1-8 The structure of the large track wheel 1 and the small track wheel 2 described herein is for illustrative purposes only. The distance between the two track wheels can be adjusted according to actual needs to avoid motion interference.

[0031] In this embodiment, as Figure 1 , Figure 3 As shown, the drive assembly includes a drive box 4, a drive shaft 26 is provided inside the drive box 4, a drive motor 25 is provided on the drive shaft 26, the drive shaft 26 passes through both ends of the drive box 4 and is connected to the drive wheel 6 of the double track wheel assembly. When the drive motor 25 is started, it drives the drive wheel 6 of the large track wheel 1 to rotate, thereby causing the large track wheel 1 to move forward.

[0032] Among them, the drive wheel 6 is the drive wheel of the track wheel commonly used in the prior art. The drive motor 25 drives the drive wheel to realize the track walking action. The small track wheel 2 is also equipped with a pulley motor 16. The pulley motor 16 is connected to the drive wheel of the small track wheel to realize the walking action of the small track wheel. The pulley motor 16 is electrically connected to the control console 10 and is controlled by the control console 10.

[0033] In this utility model, such as Figure 1 , Figure 3 , Figure 5 , Figure 8 As shown, the vehicle body includes a control console 10 and an L-frame 23. The control console 10 is located at the upper end of the L-frame 23. The control console 10 is equipped with a handrail 24. When in use, the personnel push the handrail 24. The control console 10 is equipped with a power supply 11. The control console 10 is connected to the drive assembly and the dual track wheel assembly through a wire 18. A rear wheel 28 is also provided at the corner of the L-frame 23. The rear wheel 28 forms a balance to prevent the vehicle from tipping over during the transfer. The wire 18 is covered with a rubber tube 17 to protect the wire 18 from weathering and corrosion.

[0034] In addition, the control console 10 is equipped with multiple buttons, including a start button 7, a lifting button 8, and an emergency stop button 9. These buttons allow for the start and stop of the electric motor and the lifting and lowering of the cargo components, each fulfilling a different function. The power supply 11 is housed within the control console 10 to prevent system damage in extreme weather conditions and to protect the power supply 11 and other systems from water ingress.

[0035] like Figure 1 , Figure 6 As shown, the loading assembly includes at least two electric cylinders 13, a support rod 14 that fixes the electric cylinders 13 to the drive assembly, and a loading component provided on the output shaft of the electric cylinders 13. The output shafts of the two electric cylinders 13 are also connected to baffles 12, and the output shafts of the electric cylinders 13 are also provided with slots 19.

[0036] In this embodiment, as Figure 7 As shown, the load-bearing component is a plate 20, and the side of the plate 20 is provided with a buckle 22, which is engaged with the slot 19 of the motor output shaft. Alternatively, the load-bearing component is a horizontal frame 21, and the side of the horizontal frame 21 is provided with a buckle 22, which is engaged with the slot 19 of the motor output shaft. In actual use, the load-bearing component can be replaced with a suitable basket or plate according to actual needs, which is more convenient.

[0037] exist Figure 2 , Figure 5 In the illustrated embodiment, when the start button 7 in the control panel 10 is pressed, the power supply 11 is connected to the drive box 4 via the wire 18 to provide power to the drive motor 25, and the vehicle starts to run. At the same time, the sensor 5 is activated. When the drive motor 25 starts, the output torque is buffered by the coupling and then transmitted to the drive shaft 26 in the drive box 4 for power transmission. If the sensor 5 detects a slope, it immediately sends a signal to the control panel 10. The control panel 10 controls the attitude adjustment motor 30 to start, which drives the connecting rod 3 to swing upward through the shaft 29, causing the small track wheel 2 to rise to the front of the large track wheel 1. At this time, the Z-shaped track formed by the track wheels is reconstructed into a triangular support structure due to the lifting of the small track wheel 2. By increasing the ground contact area and optimizing the force distribution, the vehicle's ability to pass through complex terrains such as slopes and potholes is improved.

[0038] exist Figure 6 In another embodiment shown, the device is activated by the lifting button 8 on the control panel 10, which powers the electric cylinder 13. The electric cylinder 13 extends or retracts its output shaft, thus moving up and down and completing the electrically controlled lifting and lowering operation. The lifting button 8 can also be used to adjust the load height.

[0039] When the adjustable conversion vehicle encounters complex terrain such as uphill slopes, the control console 10 is activated. The track wheels are connected via linkage 3, and the sensor 5 on the drive box 4 senses the terrain and transmits a signal to the control console 10. The attitude adjustment motor 30 then moves the linkage 3 to switch positions, raising the small track wheel 2 to the front of the large track wheel 1, transforming the overall track structure into a triangular track structure. This provides better power for the vehicle when driving uphill or on uneven roads, preventing slippage. Simultaneously, the small track wheel 2 is also equipped with a pulley motor, which can further provide power when climbing slopes, effectively enhancing the vehicle's adaptability to complex terrain, preventing slippage and chassis scraping, and significantly improving the efficiency and practicality of transporting materials in complex terrain.
