Description

Technical Field

[0001] This application belongs to the field of intelligent mobile platform technology, and specifically relates to an intelligent mobile platform. Background Technology

[0002] In existing technologies, intelligent mobile platforms employ a three-wheel or four-wheel wheelset structure. A three-wheel structure features a swivel wheel at the front and two drive wheels at the rear. Steering is achieved through differential control of the two drive wheels. However, this two-wheel differential control relies on the speed difference between the two wheels to generate steering torque, making it susceptible to fluctuations in ground friction and changes in load distribution. This can lead to deviations in steering trajectory and accumulated attitude angle errors, failing to meet high-precision control requirements. Consequently, intelligent mobile platforms are unsuitable for scenarios with stringent requirements for positioning and attitude accuracy and operational precision, such as industrial inspection and automated operations. Furthermore, the three-wheel setup necessitates strict control of the platform's load to prevent tipping during turns. A four-wheel structure, on the other hand, features two steering wheels at the front and two drive wheels at the rear. Steering is achieved by rotating a steering rod, which moves a connecting rod, thereby rotating the steering wheels located at both ends of the connecting rod. However, since the steering wheels only perform steering functions and do not provide power output, they are prone to slippage on low-traction surfaces or under heavy loads due to the concentrated distribution of driving force to the rear drive wheels, resulting in insufficient grip on the steering wheels. Furthermore, the four-wheel drive system can adopt a four-wheel, four-steering configuration, thus requiring the intelligent mobile platform to integrate four drive motors and four steering motors for steering control, leading to increased manufacturing complexity and hardware procurement costs. Utility Model Content

[0003] This application provides an intelligent mobility platform to solve the technical problems of poor steering accuracy, easy rollover when turning, and insufficient front wheel grip of existing intelligent mobility platforms.

[0004] This application provides an intelligent mobile platform, the technical solution of which is as follows: An intelligent mobile platform includes a main body, three front wheels located at the front end of the main body, and two rear drive wheels located at the rear end of the main body. The three front wheels are arranged sequentially at intervals along a preset direction. Each front wheel includes a drive steering wheel located in the middle and driven steering wheels located on both sides of the drive steering wheel. The two rear drive wheels are arranged relatively at intervals. The drive steering wheel and the two rear drive wheels can actively rotate to drive the movement of the intelligent mobile platform. The drive steering wheel can actively turn, and the driven steering wheels can follow the turning of the intelligent mobile platform.

[0005] The intelligent mobile platform in this application also includes the following additional technical features: Two rear drive wheels are connected to the main body through a shock absorption device, two driven steering wheels are connected to a slewing component, the slewing component is connected to the main body through a shock absorption device, the slewing component is rotatably connected to the shock absorption device, the drive steering wheel is rotatably connected to the main body through a rotating component, and the rotating component is connected to a steering motor.

[0009] The hatch is mounted on the main body, which is equipped with an electromagnetic locking device. When the hatch is closed, the electromagnetic locking device locks the hatch, and the electromagnetic locking device can also push the hatch to rotate to expose the opening.

[0010] The housing has a front drive compartment on the side near the front wheels and a rear drive compartment on the side near the rear drive wheels. The housing also has a maintenance compartment at the end opposite the opening.

[0011] The rear end of the main body is equipped with a charging device, which includes an automatic charging electrode and a manual charging device.

[0012] The rear end of the main body is also equipped with an identification guide device to guide the automatic charging electrode to automatically dock with the charging base.

[0013] The main body is equipped with anti-collision sensors at both the front and rear ends. The front, rear, left and right sides of the main body are each equipped with infrared ranging sensors for detecting distance. The front end of the main body is also equipped with a forward-looking lidar for detecting obstacles. The front end of the main body is equipped with a control box for the anti-collision sensors, infrared ranging sensors and forward-looking lidar.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. This application utilizes a five-wheel drive structure, consisting of three front wheels at the front end and two rear drive wheels at the rear. This five-point support layout provides stable support for the main body, enhancing the load-bearing capacity of the intelligent mobile platform and effectively reducing the risk of rollover during turns. The drive steering wheels and rear drive wheels work together to provide driving force, enhancing the grip of both the front and rear drive wheels and thus improving passability on complex road conditions. The intelligent mobile platform actively controls the steering angle through the drive steering wheels, with the driven steering wheels following suit. Combined with the wheel speed difference of the rear drive wheels, this improves the stability of the steering trajectory and the accuracy of attitude angle control, meeting the needs of high-precision steering scenarios such as industrial inspection and automated operations.

[0015] 2. In a preferred embodiment of this application, the two rear drive wheels and the driven steering wheel are connected to the main body via a shock-absorbing device, which can effectively buffer the impact of road bumps, improve the stability of the intelligent mobile platform when driving on uneven roads, and avoid a decrease in operational accuracy due to vibration. The rotating component connected to the driven steering wheel is rotatably connected to the shock-absorbing device, which can flexibly adjust with the steering of the intelligent mobile platform and adapt to ground undulations through the shock-absorbing device, reducing mechanical jamming and resistance during steering and ensuring smoother steering. The drive steering wheel is rotatably connected to the main body via a rotating component and is directly driven by the steering motor, which can achieve precise steering angle control. Combined with the follow-up coordination of the driven steering wheel, the steering response speed and control accuracy are further improved.

[0016] 3. As a preferred embodiment of this application, by providing a limiting protrusion in the clamping section or the rotating section, and the frame being provided with a limiting member that abuts against the limiting protrusion, the rotation angle and orientation of the rotating member can be precisely limited through the cooperation of the limiting protrusion and the limiting member, avoiding mechanical structure jamming or loss of steering angle caused by over-steering of the drive steering wheel, ensuring the effectiveness of the steering action, and improving the control stability of the drive steering wheel.

[0017] 4. As a preferred embodiment of this application, by setting two telescopic members to connect to the same mounting member, the synchronous extension and retraction of the two telescopic members provides balanced buffer support for the mounting member, improving the consistency of the shock absorption device's response to road bumps; the mobility of the mounting member can effectively absorb vibration energy, reducing the impact of uneven road surfaces on the main body and wheel assembly; by setting the rotational connection between the slewing member and the mounting member, and the connection between the support member and the mounting member, a stable shock absorption foundation is provided for the follow-up steering of the driven steering wheel and the drive of the rear drive wheel, respectively, so that the follow-up steering wheel can still maintain flexible steering during shock absorption, improving the working stability of the intelligent mobile platform.

[0018] 5. As a preferred embodiment of this application, the housing compartment has an opening on the side of the main body. The opening is directly exposed after the door is opened, allowing the battery module to be moved into or out of the housing compartment. The battery module can be placed or removed without disassembling other parts of the main body, providing a direct and spacious operation path, significantly reducing loading and unloading difficulty. This is especially beneficial when the battery module is heavy, reducing obstacles during transport and improving the convenience of replacement or maintenance. By positioning the housing compartment in the middle of the main body, the weight of the battery module is evenly distributed along the central axis of the main body, avoiding excessive local loads due to weight concentration. This ensures that the overall center of gravity of the intelligent mobile platform remains stable during driving, turning, or starting and stopping, reducing the risk of uneven wheel load, steering jamming, or tipping caused by center of gravity shift, further improving the stability and structural reliability of the intelligent mobile platform.

[0019] 6. As a preferred embodiment of this application, by setting the charging device to include an automatic charging electrode and a manual charging device, the automatic charging electrode can be adapted to automated charging equipment, the intelligent mobile platform can achieve autonomous charging without human intervention, and the manual charging device provides a flexible charging method to ensure uninterrupted power supply and improve the battery life and usage flexibility of the intelligent mobile platform.

[0020] Furthermore, through the precise positioning function of the identification guide device, the location information of the charging dock can be captured and the automatic charging electrode can be guided to dock with the charging dock, ensuring the docking accuracy between the interface and the charging dock. Moreover, docking can be completed without manual assistance, further enhancing the autonomous endurance capability of the intelligent mobile platform in unattended scenarios, reducing the interruption of the operation process due to charging operations, and enhancing the autonomy and efficiency of the intelligent mobile platform.

[0021] Furthermore, by installing anti-collision sensors at both the front and rear ends of the main body, collision risks along the direction of movement can be prioritized for detection. Combined with infrared ranging sensors positioned on the front, rear, left, and right sides of the main body, multi-angle distance monitoring is achieved, enhancing the perception capabilities of the intelligent mobile platform. By installing a forward-looking LiDAR at the front end, obstacles in the direction of travel can be accurately identified, improving the obstacle avoidance capabilities of the intelligent mobile platform. By connecting the control box to the anti-collision sensors, infrared ranging sensors, and forward-looking LiDAR, the detection signals from each sensor can be centrally received and processed, reducing signal transmission delay and improving the response speed of environmental perception and information processing.

Each front wheel 11 includes a drive steering wheel 111 located in the middle and driven steering wheels 112 located on both sides of the drive steering wheel 111. The two rear drive wheels 12 are arranged relatively at intervals. The drive steering wheel 111 and the two rear drive wheels 12 can actively rotate to drive the movement of the intelligent mobile platform. The drive steering wheel 111 can actively turn, and the driven steering wheels 112 can follow the turning of the intelligent mobile platform.

[0028] This application establishes a five-wheel structure by setting three front wheels 11 at the front end and two rear drive wheels 12 at the rear end of the main body 1. This five-point support wheel arrangement provides stable support for the main body 1, improving the load-bearing capacity of the intelligent mobile platform and effectively reducing the risk of tipping over during turns. The driving steering wheels 111 and the rear drive wheels 12 work together to provide driving force, enhancing the grip of the front wheels 111 and rear drive wheels 12, thereby improving passability on complex road conditions. The intelligent mobile platform actively controls the steering angle through the driving steering wheels 111, with the driven steering wheels 112 following suit. Combined with the speed difference of the rear drive wheels 12, this improves the stability of the steering trajectory and the accuracy of attitude angle control, meeting the needs of high-precision steering scenarios such as industrial inspection and automated operations. Those skilled in the art will understand that the preset direction is the width direction of the intelligent mobile platform. Figure 2 The horizontal direction in the middle.

[0029] As one of the preferred embodiments of this application, such as Figure 4 , Figure 5 As shown, two rear drive wheels 12 are connected to the main body 1 via a shock absorber 2, and two driven steering wheels 112 are connected to a rotating component 13. The rotating component 13 is connected to the main body 1 via the shock absorber 2, and the rotating component 13 is rotatably connected to the shock absorber 2. The drive steering wheel 111 is rotatably connected to the main body 1 via a rotating component 14, which is connected to a steering motor. The steering motor can be a servo motor, a steering gear, etc., and has a built-in high-precision encoder that can sense and adjust the steering angle of the drive steering wheel 11.

[0030] The two rear drive wheels 12 and the driven steering wheel 112 are connected to the main body 1 through the shock absorption device 2, which can effectively buffer the impact of road bumps, improve the stability of the intelligent mobile platform when driving on uneven roads, and avoid the decrease in work accuracy due to vibration. The rotary component 13 connected to the driven steering wheel 112 is rotatably connected to the shock absorption device 2, which can flexibly adjust with the turn of the intelligent mobile platform, and can also adapt to the undulation of the ground through the shock absorption device 2, reducing mechanical jamming and resistance during turning, and ensuring smoother turning action; the drive steering wheel 111 is rotatably connected to the main body 1 through the rotating component 14 and is directly driven by the steering motor, which can realize precise steering angle control. With the follow-up coordination of the driven steering wheel 112, the steering response speed and control accuracy are further improved.

[0031] As a preferred embodiment of the implementation method, the following is an example: Figure 4 , Figure 5 As shown, the rotating component 14 includes a clamping section 141 rotatably connected to the drive steering wheel 111 and a rotating section 142 connected to the main body 1. The clamping section 141 or the rotating section 142 is provided with a limiting protrusion 143. The main body 1 includes a frame 15, and the rotating component 14 is rotatably connected to the frame 15. The frame 15 is provided with a limiting member 151 that abuts against the limiting protrusion 143. Preferably, a drive motor is disposed in the clamping section 141 to drive the drive steering wheel 111 to rotate.

[0032] By providing a limiting protrusion 143 in the clamping section 141 or the rotating section 142, and a limiting member 151 that abuts against the limiting protrusion 143 in the frame 15, the rotation angle and orientation of the rotating member 14 can be precisely limited through the cooperation of the limiting protrusion 143 and the limiting member 151, so as to avoid mechanical structure jamming or loss of steering angle caused by excessive steering of the drive steering wheel 111, ensuring the effectiveness of steering action and improving the control stability of the drive steering wheel 111.

[0033] As a preferred embodiment of the implementation method, the following is a second preferred embodiment: Figure 4 , Figure 5 As shown, the shock absorption device 2 includes two telescopic members 21 connected to the main body 1. The ends of the two telescopic members 21 opposite to the main body 1 are connected to a mounting member 22. The mounting member 22 can move relative to the main body 1. The rotating member 13 is rotatably connected to the mounting member 22. The intelligent mobile platform also includes a support member 3 rotatably connected to the rear drive wheel 12. The support member 3 is connected to the mounting member 22. The drive motor is set on the support member 3 to drive the rear drive wheel 12 to rotate.

[0034] By setting two telescopic components 21 to connect to the same mounting component 22, the synchronous extension and retraction of the two telescopic components 21 provides balanced buffer support for the mounting component 22, improving the consistency of the shock absorption device 2's response to road bumps; the mobility of the mounting component 22 can effectively absorb vibration energy, reducing the impact of uneven road surfaces on the main body 1 and wheel set; by setting the rotational connection between the slewing component 13 and the mounting component 22, and the connection between the support component 3 and the mounting component 22, a stable shock absorption foundation is provided for the follow-up steering of the driven steering wheel 112 and the drive of the rear drive wheel 12, respectively, so that the follow-up steering wheel can still maintain flexible steering during shock absorption, improving the working stability of the intelligent mobile platform.

[0035] In this application, the power supply configuration of the intelligent mobile platform can be any of the following embodiments: Implementation Method Two: (e.g.) Figure 1 , Figure 4 , Figure 6 As shown, the intelligent mobile platform also includes a storage compartment 4 located in the middle of the main body 1. The storage compartment 4 is used to store the battery module 5. The battery module 5 is movably disposed in the storage compartment 4. The storage compartment 4 has an opening 41 on the side of the main body 1. The storage compartment 4 also has a door 42. The door 42 has a closed state that closes the opening 41 and an open state that exposes the opening 41.

[0036] The housing 4 has an opening 41 on the side of the main body 1. After the door 42 is opened, the opening 41 can be directly exposed, allowing the battery module 5 to be moved into or out of the housing 4. The battery module 5 can be placed or removed without disassembling other parts of the main body 1. The operation path is direct and the space is open, which greatly reduces the difficulty of loading and unloading. Especially when the battery module 5 is heavy, it can reduce obstacles during transportation and improve the convenience of replacement or maintenance. By setting the housing 4 in the middle of the main body 1, the weight of the battery module 5 is evenly distributed on the central axis of the main body 1, avoiding excessive local load due to weight concentration. This ensures that the overall center of gravity of the intelligent mobile platform remains in a stable area during driving, turning, or starting and stopping, reducing the risk of uneven wheel force, steering jamming, or tipping caused by center of gravity shift, and further improving the smoothness and structural reliability of the intelligent mobile platform.

[0037] Furthermore, the hatch 42 is rotatably mounted on the main body 1, and the main body 1 is equipped with an electromagnetic locking device (not shown in the attached figure). When the hatch 42 is in the closed state, the electromagnetic locking device locks the hatch 42. The electromagnetic locking device can push the hatch 42 to rotate and expose the opening 41. This application does not limit the control method of the electromagnetic locking device; it can be controlled by an operation button located on the main body 1 or by remote control to open the hatch 42, thereby facilitating the replacement of the battery module 5.

[0038] Furthermore, a front drive compartment 7 is provided on the side of the housing compartment 4 near the front wheel 11, and a rear drive compartment 8 is provided on the side near the rear drive wheel 12. A maintenance compartment 9 is provided at the end of the housing compartment 4 away from the opening 41. The intelligent mobile platform is provided with a partition (not shown in the attached figure) on the top of the housing compartment 4, the front drive compartment 7, and the rear drive compartment 8. The intelligent mobile platform is also provided with a top plate (not shown in the attached figure). A control compartment (not shown in the attached figure) is formed between the top plate and the partition. The control compartment is used to house the control components of the intelligent mobile platform, realize the compartmentalized management of each functional component, facilitate the installation and maintenance of each functional component, and improve the heat dissipation capacity of each functional component.

[0039] Implementation Method 3: This implementation method 3 is not illustrated. The difference from implementation method 2 is that the accommodating compartment has an opening at the top of the main body.

[0040] As a preferred embodiment of this application: such as Figure 1 , Figure 2 , Figure 3 As shown, the rear end of the main body 1 is provided with a charging device 16, which includes an automatic charging electrode 161 and a manual charging device 162.

[0041] By setting the charging device 16 to include an automatic charging electrode 161 and a manual charging device 162, the automatic charging electrode 161 can be adapted to automated charging equipment, enabling the intelligent mobile platform to charge autonomously without human intervention. The manual charging device 162 provides a flexible charging method, ensuring uninterrupted power supply and improving the battery life and usability of the intelligent mobile platform.

[0042] As a preferred option, such as Figure 1 , Figure 2 , Figure 3 As shown, the rear end of the main body 1 is also equipped with an identification and guidance device to guide the automatic charging electrode 161 to automatically dock with the charging base. Through the precise positioning function of the identification and guidance device, the location information of the charging base can be captured and the automatic charging electrode 161 can be guided to dock with the charging base, ensuring the docking accuracy between the interface and the charging base. Moreover, docking can be completed without manual assistance, further improving the autonomous endurance of the intelligent mobile platform in unattended scenarios, reducing the interruption of the operation process due to charging operations, and enhancing the autonomy and efficiency of the intelligent mobile platform. The identification and guidance device includes a camera 18 located at the rear end of the main body 1, which enables the intelligent mobile platform to navigate and automatically reach the charging location.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 3As shown, the main body 1 has anti-collision sensors (not shown in the attached diagram) at both its front and rear ends. Infrared ranging sensors (not shown in the attached diagram) for distance detection are located on the front, rear, left, and right sides of the main body 1. A forward-looking LiDAR 17 for obstacle detection is also located at the front of the main body 1. The front of the main body 1 also includes a control box 6 for the anti-collision sensors, infrared ranging sensors, and the forward-looking LiDAR 17. Anti-collision strips are provided along the circumference of the main body 1 to improve the avoidance of hard contact between the main body 1 and obstacles. Preferably, cameras 18 are located on both sides of the forward-looking LiDAR 17, and an ultrasonic radar is also located at the front of the main body 1 to obtain information about the front of the intelligent mobile platform during its movement.

[0044] By installing anti-collision sensors at both ends of the main body 1, collision risks along the direction of movement (front / back) can be prioritized. Combined with infrared ranging sensors located on the front, rear, left, and right sides of the main body 1, multi-angle distance monitoring is achieved, improving the perception capabilities of the intelligent mobile platform. A forward-looking LiDAR 17 at the front end can accurately identify obstacles in the direction of travel, enhancing the obstacle avoidance capabilities of the intelligent mobile platform. By connecting the control box 6 to the anti-collision sensors, infrared ranging sensors, and forward-looking LiDAR 17, the detection signals from each sensor can be centrally received and processed, reducing signal transmission delay and improving the response speed of environmental perception and information processing.
