[0002] Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce new intelligent machines that can respond in a similar way to human intelligence. Research in this field includes robotics, speech recognition, image recognition, natural language processing, and expert systems.
[0003] Obstacle avoidance is a key technology for unmanned driving. Accurately detecting obstacles ahead and safely passing through obstacles to reach the destination are the prerequisites for smart cars to travel in complex working environments. The existing technology provides "an artificial intelligence automatic obstacle avoidance device", which mainly avoids obstacles by raising the height of the entire chassis. However, when the chassis load is too large, it becomes more difficult to lift the chassis, and the energy consumption of obstacle avoidance is high. After lifting, the overall center of gravity of the chassis rises, resulting in poor stability of the chassis and reduced safety. Summary of the invention
[0004] The present invention provides an automatic obstacle avoidance device based on artificial intelligence, which solves the technical problems of the existing obstacle avoidance devices, such as high difficulty in achieving obstacle avoidance, poor device stability and low safety.
[0005] In order to solve the above technical problems, the present invention provides an automatic obstacle avoidance device based on artificial intelligence, comprising a base, a main control module fixed on the base, an environment acquisition module, and multiple groups of one-to-one corresponding steering drive modules and displacement drive modules; the steering drive module comprises a first power assembly and a second power assembly, and the first power assembly is gear-connected with the second power assembly; the displacement drive module comprises a third power assembly and a walking wheel; the walking wheel is shaft-connected with the second power assembly;
[0006] The environment acquisition module is used to obtain the surrounding environment information and feed it back to the main control module;
[0007] The main control module is used to generate a control command for path movement according to the preset planned path and the environmental information;
[0008] The third power assembly is used to respond to the control command to drive the walking wheel to rotate to complete the movement of the device;
[0009] The first power assembly is started under the control of the control command, and drives the second power assembly to rotate, thereby driving the walking wheel to rotate horizontally to complete the steering of the device.
[0010] This basic solution adds an environment acquisition module to scan the scene around the device and transmit it to the main control module for processing and analysis, and then re-plans the travel path based on the preset planned path and the environmental information (and generates corresponding control commands). At this time, under the control of the control command, the first power assembly, the second power assembly, and the third power assembly are driven respectively, wherein the combined action of the first power assembly and the second power assembly drives the walking wheel to rotate horizontally to complete the device turning, and the third power assembly drives the walking wheel to rotate to complete the device movement. By continuously scanning the scene around the device, the device can effectively avoid collisions with obstacles during turning and displacement, and the device has strong stability and high safety performance.
[0011] In a further embodiment, the first power assembly comprises an electric push rod, a slide plate and a servo motor connected in sequence, and a first gear connected to the servo motor shaft; the fixed end of the electric push rod is fixed to the base, and the movable end is movably connected to the fixed end through the push rod; the slide plate is horizontally installed on the upper part of the movable end; the servo motor is installed on the top of the slide plate, and its rotating shaft passes through the slide plate and extends to the bottom of the slide plate; the first gear is installed on the rotating shaft;
[0012] When the control command includes a steering instruction, the electric push rod is activated, pushing the skateboard to slide on the base, driving the servo motor to move outward until the first gear is connected to the gear of the second power component; then, driven by the servo motor, the first gear drives the second power component to rotate to control the steering of the walking wheel.
[0013] This solution sets up a first power assembly with an electric push rod and a servo motor as the core. Under the action of the electric push rod, when the device moves in a straight line, the first power assembly is separated from the second power assembly to ensure that the travel wheel maintains movement in a specific direction; when the device is turning, the first power assembly is pushed to engage the gears of the second power assembly to drive the travel wheel to turn horizontally, thereby completing the steering of the device. The structure is compact, the layout is reasonable, and the steering efficiency is high.

[0015] When the control command includes a steering instruction, the first gear drives the second gear to rotate, and the second gear drives the rotating rod to rotate horizontally, so that the mounting tube also rotates synchronously, thereby controlling the walking wheel installed at the bottom of the mounting tube to complete the steering.
[0016] In this solution, the second gear and the rotating rod are movably installed on the support plate to ensure the stability of the installation structure. When a steering command is received, the driven second gear drives the rotating rod to rotate horizontally, thereby synchronously rotating the walking wheel installed at the bottom of the mounting cylinder to a preset angle, thereby quickly completing the steering and cooperating with the environment acquisition module to complete automatic obstacle avoidance.
[0017] In a further embodiment, the base comprises a base plate, a support rod, a support frame and a protective pad, wherein the support rods are radially distributed and installed on the side of the base plate; the support frame is installed around the outer end of the support rod; the main control module is installed at the bottom of the base plate; the protective pad is an arc-shaped covering structure that fits the edge of the support frame, and a mounting through hole is provided in the middle thereof for installing the environment collection module; the first power assembly is installed on the support rod;

[0019] This solution takes the base as the center point, and sets support rods, support frames and protective pads outward in sequence to form a stable base support structure. The load-bearing plate is installed on the base through sleeves and support columns. Combined with the guide rods installed on the edge and the guide grooves, the stability of the load-bearing plate can be further improved, thereby improving transportation stability.

[0022] When the control computer detects a severe collision, it controls the gas generating device to start and inflate the airbag for collision protection.
[0023] In this solution, the control computer and the gas generating device are installed in an embedded form in the load-bearing plate, and the airbag is embedded in an annular groove on the side of the load-bearing plate in a surround manner. When the control computer detects a severe collision, the gas generating device is controlled to start and inflate the airbag for collision protection.

[0027] In a further embodiment, the present invention comprises at least three groups of the steering drive modules and the displacement drive modules, and each group of the steering drive modules and the displacement drive modules is independently connected to the main control module;
[0028] When the control command only includes a movement instruction, the three groups of steering drive modules are controlled to drive the three groups of displacement drive modules to move horizontally, so that the three groups of walking wheels maintain the same direction; at this time, all the third power components are controlled to drive the walking wheels to rotate, so as to complete the movement of the device;

[0063] In this embodiment, the base plate 11 is taken as the center point, and support rods 12, support frames 13 and protective pads 14 are arranged outward in sequence to form a stable base support structure.

Its bottom surface, which is parallel to the ground and higher than the lowest point of the running wheel 52, can push away smaller obstacles that affect the movement of the device (such as impurities such as mud or gravel on the ground) without affecting the normal movement of the device.

[0067] In this embodiment, the present invention comprises at least three groups of steering drive modules 4 and displacement drive modules 5, and each group of steering drive modules 4 and displacement drive modules 5 is independently connected to the main control module 2;
[0068] When the control command only includes a movement instruction, the three steering drive modules 4 are controlled to drive the three displacement drive modules 5 to move horizontally, so that the three walking wheels 52 maintain the same direction; at this time, all the third power components 51 are controlled to drive the walking wheels 52 to rotate, so as to complete the movement of the device;
[0069] When the control command includes a steering instruction, a group of steering drive modules 4 at the rear is controlled to drive the corresponding displacement drive module 5 to move horizontally at a predetermined angle, and the corresponding third power component 51 is controlled to drive the walking wheel 52 to rotate, and the other two groups of steering drive modules 4 and displacement drive modules 5 are controlled to be stable and motionless, thereby completing the steering control in the forward direction and completing the steering of the device.
[0070] This embodiment is provided with three groups of steering drive modules 4 and displacement drive modules 5. When the device needs to turn, one group that originally bears the function of the driving wheel is controlled to remain stationary. According to actual needs, any electric push rod 411 in the other two groups is started to drive the slide plate 412 and the servo motor 413 to move, control the corresponding walking wheel 52 to move horizontally at a predetermined angle, and cooperate with the third power component 51 of the same group to rotate with the originally stationary walking wheel 52 as the axis point, so that the device rotates, and the steering operation of the device can be completed.

At the same time, the other two groups of steering drive modules 4 and displacement drive modules 5 are controlled to be stable and immobile, and rotate with the originally stationary walking wheel 52 (that is, the front walking wheel 52 with the original forward direction of the device as the front, or a group of walking wheels 52 that originally served as the driving wheel function) as the axis point, thereby completing the steering control in the forward direction and completing the steering of the device.
[0076] The embodiment of the present invention adds an environment acquisition module 3 to perform image scanning of the scene around the device and transmit it to the main control module 2 for processing and analysis, and then re-plans the travel path based on the preset planned path in combination with the environmental information (and generates corresponding control commands). At this time, under the control of the control command, the first power component 41, the second power component 42, and the third power component 51 are driven respectively, wherein the combined action of the first power component 41 and the second power component 42 drives the walking wheel 52 to rotate horizontally to complete the device turning, and the third power component 51 drives the walking wheel 52 to rotate to complete the device movement. By continuously performing image scanning of the scene around the device, the device can effectively avoid collision with obstacles during turning and displacement, and the device has strong stability and high safety performance.
