[0043] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] Please refer to Figure 1 , the present invention provides a technical solution: an integrated walking motor, including a motor body 1, and an output shaft control module and an electric control module are respectively installed on both sides of the motor body 1;

[0045] The output shaft control module includes a braking coil 3 installed at the output end of the motor body 1, and a speed reducer 4 installed on the other side of the braking coil 3. The braking coil 3 and the speed reducer 4 share the end cover of the speed reducer 4;

[0046] The electric control module includes a motor controller 2 installed on the back of the motor body 1. The motor body 1 and the motor controller 2 share the end cover of the motor controller 2.

[0047] The assembly structure with shared end covers facilitates the vehicle manufacturer to arrange the whole vehicle according to the aerial work vehicle used in pairing, making the vehicle space effectively utilized; at the same time, because the end cover and the body are shared in the whole system, the weight is reduced, the whole vehicle is lightened, which is beneficial to improving the endurance.

[0048] Specifically, as Figure 1 shown, the braking coil 3 is fixedly connected to both the speed reducer 4 and the motor body 1 by bolts, and the motor body 1 is fixedly connected to the motor controller 2 by bolts.

[0049] The braking coil 3 can quickly cut off the power supply of the motor, stop the motor from running, achieve rapid braking, and protect the motor and the mechanical system from damage through emergency power-off.

[0050] The speed reducer 4 can reduce the high speed of the motor to the required low speed, and at the same time, according to the transmission ratio of the gears, increase the output torque while reducing the speed, that is, provide a greater torque to drive the load.

[0051] The electric control module includes a motor controller 2 installed at the rear end of the motor body 1 and sharing the end cover of the motor body 1. The motor body 1 is a permanent magnet synchronous motor.

[0052] The motor body 1 adopts a permanent magnet synchronous motor to reduce the use of wire harnesses, increase the efficiency of the entire walking system, which is beneficial to reducing the battery power and the cost of the whole vehicle. The motor controller 2 is connected to the motor body 1 through three-phase wires to drive the motor body 1. The three-phase wires are connected to the power board of the motor body 1 in an internally assembled manner.

[0053] The motor controller 2 can control the speed of the motor according to the set parameters or external input signals to achieve precise speed and torque regulation.

[0054] Sealing rings are provided at the joints of the brake coil 3 with the reducer 4 and the motor body 1, and at the joint of the motor body 1 with the motor controller 2. The sealing rings play a waterproof role, enabling the motor to reach the IP67 waterproof level. This walking motor provides an integrated design solution. As long as the host factory considers the specifications of the later tires and changes the end cover of the reducer 4 to match the tires, it can achieve technological upgrading, meeting the goals of simplified installation, optimized layout, convenient maintenance, and low cost. At the same time, the overall waterproof level can reach IP67, increasing the system reliability.

[0055] Specifically, please refer to Figure 2 , the present invention further includes a sensing integration module, a motor compensation analysis module, and a dynamic compensation analysis module;

[0056] The sensing integration module is used to monitor the real-time operation information and environmental information of the motor body 1; among them, the real-time operation information includes the shaft speed, temperature, and torque of the motor body 1, and the environmental information includes temperature, humidity, and vibration;

[0057] The motor compensation analysis module is used to receive the real-time operation information and environmental information of the motor body 1; perform a state analysis on the real-time operation information of the motor body 1 to obtain the state compensation value of the motor body 1; perform an environmental analysis on the environmental information of the motor body 1 to obtain the environmental compensation value of the motor body 1; perform a weighted processing on the state compensation value and the environmental compensation value to obtain a comprehensive compensation value;

[0058] The dynamic compensation analysis module is used to perform a dynamic analysis on the comprehensive compensation value of the motor body 1 to obtain a comprehensive abnormal compensation value and a partition compensation broken line graph; set an abnormal compensation threshold. If the comprehensive abnormal compensation value is greater than or equal to the abnormal compensation threshold, a compensation abnormal signaling is generated; if the comprehensive abnormal compensation value is less than the abnormal compensation threshold, it indicates that the operating state of the motor body 1 is relatively good;

[0059] The electronic control module is also used to receive the comprehensive compensation value sent by the motor compensation analysis module to dynamically adjust the output power of the motor body 1, and control the output shaft control module on the motor body 1 to adjust the rotation speed and torque of the motor body 1; it is also used to receive the compensation exception signaling. When receiving the compensation exception signaling, it controls the motor body 1 to stop running, and marks the compensation exception signaling, the position, number, and partition compensation broken line graph of the motor body 1 as compensation maintenance information, and sends the compensation maintenance information to the corresponding maintenance personnel.

[0060] It should be noted that the sensing integration module, motor compensation analysis module, dynamic compensation analysis module, and electronic control module in the present invention cooperate with each other to form a complete motor operation monitoring and compensation system. Through the sensing integration module, the operation information and environmental information of the motor body 1 can be comprehensively and real-time monitored, providing an accurate data basis for subsequent analysis and adjustment. Among them, the motor compensation analysis module analyzes the real-time operation information and environmental information respectively to obtain the state compensation value and environmental compensation value, and further weights them to obtain the comprehensive compensation value, realizing the multi-dimensional evaluation and compensation of the motor operation state; the dynamic compensation analysis module dynamically analyzes the comprehensive compensation value, which can not only obtain the comprehensive abnormal compensation value to judge whether the motor operation is abnormal, but also generate a partition compensation broken line graph to intuitively display the change trend of the motor compensation value, providing a strong basis for fault diagnosis and maintenance. The electronic control module dynamically adjusts the output power and rotation speed torque of the motor according to the comprehensive compensation value to achieve intelligent control. At the same time, when receiving the compensation exception signaling, it stops the motor operation in time and sends the compensation maintenance information to ensure the safe and reliable operation of the motor; in summary, through the collaborative work of multiple modules, the problem that the compensation function of the existing walking motor is not accurate and intelligent enough and lacks dynamic adjustment according to the actual operation state and environmental changes of the motor is effectively solved, meeting the requirements of modern equipment for efficient and stable operation.
