[0025] This application provides a multi-functional four-wheel drive electric flatbed cart, solving the problems of insufficient power and unstable driving that single-wheel drive electric flatbed carts easily encounter in transportation environments with complex road conditions; and the difficulty in adjusting the position and posture of the loaded workpiece according to actual needs during transportation, which limits its application range. It achieves diversified transportation and position and posture adjustment functions through intelligent control and a multi-functional adjustment structure, meeting the complex needs of industrial scenarios.

[0026] This utility model discloses a multifunctional four-wheel drive electric flatbed vehicle.

[0027] Example 1: According to the appendix Figure 1-3 As shown, the system includes a vehicle body structure 1, a voltage regulator assembly 2, a frequency converter 3, a laser obstacle avoidance unit 4, a dual-shaft motor 5, a transformer 6, an electrical control box, an optical communication assembly 10, a laser ranging assembly 11, a multi-functional adjustment structure 12, a cover plate assembly 13, a four-wheel drive structure 14, a power supply system 15, a drive wheel structure 16, a limit switch 17, and a warning light 18. The power supply system 15 draws power from the low-voltage rail, which is converted into a standard working voltage by the transformer 6 before supplying power. The dual-shaft motor 5 drives the four-wheel drive structure 14 to drive the drive wheel structure 16. The multi-functional adjustment structure 12 rotates or flips according to the information from the optical communication assembly 10.

[0028] The four-wheel drive structure 14 enables the electric flatbed cart to accelerate quickly and adapt to various complex road conditions. Compared with traditional single-drive flatbed carts, it can operate stably in harsher environments, improving transportation efficiency. The multi-functional adjustment structure 12, combined with the optical communication assembly 10, can adjust the position and orientation of the load workpiece according to the needs of the host computer, expanding the application scenarios of the electric flatbed cart and meeting the special requirements of different industrial production processes for material position and orientation. The laser obstacle avoidance unit 4, in conjunction with the warning lights 18, monitors the driving environment in real time, promptly reports obstacle information and issues alarms, ensuring the safe operation of the electric flatbed cart. The laser ranging assembly 11 provides precise position information for vehicle movement, enabling the electric flatbed cart to accurately perform actions such as forward, backward, acceleration, deceleration, and braking. The voltage regulator assembly 2, frequency converter 3, and other components work together to ensure that each functional module operates efficiently under suitable voltage and operating conditions, improving the reliability and energy efficiency of the equipment.

[0029] Furthermore, the vehicle body structure 1 is a frame structure assembled and welded from sheet metal, used to bear and distribute loads, and to provide fixed and protective space for each functional module.

[0030] Furthermore, the voltage regulator assembly 2 contains 6 voltage regulators, which are divided into three groups. Each group corresponds to a specific output voltage value, and each voltage regulator is equipped with an adjustment knob.

[0031] Furthermore, the frequency converter 3 is installed inside the frequency converter box 8 to adjust the frequency and build a dynamic adaptation system of "operating condition-frequency-speed".

[0032] Specifically disclosed, the laser obstacle avoidance unit 4 is fixed at both ends of the vehicle frame structure to identify obstacles and feed the obstacle information back to the main electrical control box 7.

[0033] Specifically disclosed, the electrical control box includes a main electrical control box 7, a frequency converter box 8, and a test equipment mounting box 9. The main electrical control box 7 is the intelligent control hub, the frequency converter box 8 protects the frequency converter 3, and the test equipment mounting box 9 is used to install other modules.

[0034] It is important to emphasize that the four-wheel drive structure 14 includes a coupling, a steering gearbox, and gears, which are used to connect the dual output shaft motor 5 and the drive wheel structure 16 to convert rotational kinetic energy into vertical kinetic energy.

[0035] Example 2: According to the appendix Figure 1-3As shown, the system includes a vehicle body structure 1, a voltage regulator assembly 2, a frequency converter 3, a laser obstacle avoidance unit 4, a dual-shaft motor 5, a transformer 6, an electrical control box, an optical communication assembly 10, a laser ranging assembly 11, a multi-functional adjustment structure 12, a cover plate assembly 13, a four-wheel drive structure 14, a power supply system 15, a drive wheel structure 16, a limit switch 17, and a warning light 18. The power supply system 15 draws power from the low-voltage rail, which is converted into a standard working voltage by the transformer 6 before supplying power. The dual-shaft motor 5 drives the four-wheel drive structure 14 to drive the drive wheel structure 16. The multi-functional adjustment structure 12 rotates or flips according to the information from the optical communication assembly 10.

[0036] It is worth emphasizing that the drive wheel structure 16 adopts a through-shaft structure design, including two single-rimmed wheels with steel cores and rubber material, a connecting shaft, and a drive gear. The drive gear is fixed on the connecting shaft to obtain rotational kinetic energy.

[0037] Working principle: The power acquisition system 15 obtains electrical energy from the low-voltage rail, which is then converted into the working voltage required by the electric flatcar system by the transformer 6 and supplied to the dual-output shaft motor 5 and the voltage regulator assembly 2. The voltage regulator assembly 2 converts the voltage output by the transformer 6 into the working voltage required by other functional components. When the dual-output shaft motor 5 rotates clockwise, the right output shaft outputs kinetic energy to the connecting shaft of the front drive wheel structure in the drive wheel structure 16 through the four-wheel drive structure 14. The rotation of the connecting shaft drives the front wheel to rotate synchronously, dragging the electric flatcar to perform forward movement. At the same time, the left output shaft outputs kinetic energy to the connecting shaft of the rear drive wheel structure in the drive wheel structure 16 through the four-wheel drive structure 14. The rotation of the connecting shaft drives the rear wheel to rotate synchronously, pushing the electric flatcar to perform forward movement. When the dual-output shaft motor 5 rotates counterclockwise, the right output shaft outputs kinetic energy to the connecting shaft of the front drive wheel structure in the drive wheel structure 16 through the four-wheel drive structure 14. The rotation of the connecting shaft drives the front wheel to rotate synchronously, dragging the electric flatcar to perform a backward movement. At the same time, the left output shaft outputs kinetic energy to the connecting shaft of the rear drive wheel structure in the drive wheel structure 16 through the four-wheel drive structure 14. The rotation of the connecting shaft drives the rear wheel to rotate synchronously, pushing the electric flatcar to perform a backward movement. The laser obstacle avoidance unit 4 detects obstacles on the travel route in real time to ensure the safe and stable operation of the electric flatbed cart. The laser ranging assembly 11 maps the position information of the electric flatbed cart in real time. Based on the information mapped by the laser obstacle avoidance unit 4 and the laser ranging assembly 11, the main control box 7 adjusts the output frequency of the inverter 3 in real time to enable the electric flatbed cart to execute acceleration, deceleration, braking and other action commands. When the electric flatbed cart feeds back the information of running to the designated work location to the main control box 7 through the limit switch 17, the electric flatbed cart adjusts the output frequency of the inverter 3 in a timely manner to execute braking action. The optical communication assembly 10 receives the pose information from the host computer and converts it into the pose requirements of the workpiece being carried. The main control box 7 issues corresponding posture adjustment parameter commands to the multi-functional adjustment structure 12 contained in the electric flatcar. The relevant drive units contained in the multi-functional adjustment structure 12 perform rotation and flipping actions. The posture of the workpiece carried by the electric flatcar matches the posture required by the host computer. This posture adjustment process adopts the management mode of absolute difference control logic. When the positive or negative deviation of the actual posture of the workpiece exceeds the preset deviation range, it is determined that the posture adjustment is not in place. When the adjustment mechanism still cannot meet the posture requirements of the host computer after running to the limit position, the main control box 7 will issue an alarm message through the warning alarm light 18 to notify personnel to intervene and further adjust the posture requirements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
