Therefore, the statements "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. "Multiple" refers to two or more.

[0061] The first aspect of the embodiment of the present application provides a mobile platform, such as Figures 1 to 3 As shown, the mobile platform includes a frame 10, a power supply assembly 20, a mobile assembly 30 and a shock absorbing assembly 40;

[0062] The power supply assembly 20 is mounted on the frame 10;

[0063] The mobile assembly 30 includes a driving wheel group 31 and a supporting wheel group 32 mounted on one side of the frame 10. The supporting wheel group 32 and the driving wheel group 31 are spaced apart and arranged side by side. The driving wheel group 31 is connected to the power supply assembly 20. The driving wheel group 31 is used to provide driving force to the mobile platform to move the mobile platform forward or backward. The driving wheel group 31 includes a first driving wheel 311 and a second driving wheel 312 arranged side by side and spaced apart. By controlling the speed difference between the first driving wheel 311 and the second driving wheel 312, the mobile platform can achieve left and right steering through the speed difference. The supporting wheel group 32 is used to support the mobile platform and assist the mobile platform in steering.

[0064] The shock absorbing assembly 40 is mounted on the frame 10 and connected to the driving wheel set 31 . The shock absorbing assembly 40 is used to reduce the vibration and impact of the driving wheel set 31 caused by uneven road surface during rotation and movement.

[0065] The mobile platform provided in the embodiment of the present application utilizes the first drive wheel 311 and the second drive wheel 312 in the drive wheel assembly 31 to coordinate and adjust the direction of movement of the mobile platform through the speed difference between the first and second drive wheels. This effectively improves the applicability of the mobile platform and intelligent robot, making it suitable for complex application scenarios. The mobile platform's drive wheel assembly 31 is equipped with a shock-absorbing assembly 40, which allows for left and right shock absorption and balancing of the drive wheel assembly 31 under heavy loads, avoiding the risk of wheel tilt under heavy pressure caused by a single-sided configuration of the conventional robot's shock-absorbing assembly 40. Furthermore, the shock-absorbing capacity of the disc is enhanced, resulting in smoother shock absorption.

[0066] In application, a differential mode is adopted for the two rollers in the driving wheel group 31. Specifically, the first driving wheel 311 and the second driving wheel 312 can realize the steering of the mobile platform or intelligent robot by adjusting the speed difference between them. The specific working principle is linear movement: when the two directional wheels rotate in the same direction at the same speed, the entire device will move forward or backward in a straight line. Steering: Turning left: The directional wheel on the right accelerates, while the directional wheel on the left slows down or remains unchanged. In this way, since the thrust generated by the right wheel is greater than that of the left, the device will deflect to the left. Turning right: In contrast to the above situation, the directional wheel on the left accelerates, and the directional wheel on the right slows down or remains unchanged, causing the device to deflect to the right. Rotating in place: If the two directional wheels rotate at the same speed but in opposite directions, the device will rotate in place. For example, the right wheel rotates clockwise and the left wheel rotates counterclockwise, which will cause the device to rotate around its center point.

[0067] In some embodiments, as Figure 1 and Figure 2As shown, the first drive wheel 311 and the second drive wheel 312 are respectively arranged on both sides of the frame 10, so that the stable movement of the entire mobile platform can be stably controlled. The support wheel group 32 includes a first roller 321 and a second roller 322 arranged side by side and at intervals. There is a speed difference between the first roller 321 and the second roller 322, and the first roller 321 and the second roller 322 are universal wheels. Auxiliary steering can also be achieved by controlling the differential speed of the first roller 321 and the second roller 322 in each support wheel group 32. The specific implementation principle is the same as the speed difference between the first drive wheel 311 and the second drive wheel 312. It should be noted that, precisely because there is a speed difference between the first roller and the second roller of the support wheel group, the friction of the mobile platform on the ground can be increased, and the operation is more stable.

[0068] In some embodiments, as Figure 1 and Figure 2 As shown, multiple shock-absorbing assemblies 40 are provided, one on each side of the drive wheel assembly 31. In use, the drive wheel assembly 31 utilizes dual spring damping, with a shock-absorbing spring 43 positioned on each left and right side of the drive wheel assembly 31. Each spring is topped with a guide shaft 42 to direct the spring's direction of movement. This ensures left-right wheel damping and balancing under heavy loads. This eliminates the risk of wheel roll under heavy loads, as occurs with conventional robots with shock-absorbing springs 43 positioned on one side. The chassis achieves enhanced shock absorption and smoother vibration reduction.

[0069] In some embodiments, as Figures 1 to 3 As shown, a set of shock absorbing components 40 provided on both sides of the driving wheel assembly 31 includes a linear bearing 41, a guide shaft 42 and a shock absorbing spring 43;

[0070] One end of the linear bearing 41 is fixed to the side of the frame 10 away from the driving wheel group 31, and the other end of the linear bearing 41 passes through the frame 10 and extends toward the direction where the driving wheel group 31 is located;

[0071] One end of the guide shaft 42 is slidably inserted into the linear bearing 41, and the other end of the guide shaft 42 is connected to the rotating shaft of the driving wheel assembly 31;

[0072] A damping spring 43 is mounted on the linear bearing 41 and the guide shaft 42, with one end of the spring 43 contacting the frame 10 and the other end contacting the rotating shaft of the drive wheel assembly 31. When the road surface is uneven, the wheel is subjected to pressure that rebounds to the damping spring 43. The damping spring 43 and the linear bearing 41 move and compress, absorbing the vibration and preventing the entire mobile robot from vibrating, thus achieving a shock-absorbing effect.

[0073] In some embodiments, as Figure 3As shown, there are multiple groups of support wheel groups 32, each group of support wheel groups 32 includes a first roller 321 and a second roller 322. The support wheel groups 32 are arranged along the front and rear of the driving wheel group 31, and the support wheel groups 32 and the driving wheel group 31 are evenly distributed on both sides of the frame 10 to stably support the mobile platform. In a preferred embodiment, there are four groups of support wheel groups 32, and every two groups of support wheel groups 32 correspond to a group of support wheel groups 32 arranged front and back, that is, one driving wheel group 31 and two support wheel groups 32 are distributed on the left and right sides of the frame 10 respectively, and two groups of support wheel groups 32 are distributed at the front and rear ends of the frame 10. With this arrangement, the driving wheel groups 31 located on both sides of the middle of the frame 10 mainly provide driving force and steering functions to enable the entire mobile platform to move, while the support wheel groups 32 not only provide the function of assisting steering, but also play a role in balancing and supporting the entire mobile platform. In other embodiments, the supporting wheel groups 32 may be provided in two groups, six groups, etc., as long as the supporting wheel groups 32 can be evenly distributed on the frame 10, thereby ensuring stable support and auxiliary steering functions.

[0074] In some embodiments, the support wheels include a shock-absorbing structure, which is separate from the shock-absorbing assembly and is used to reduce vibration and impact caused by uneven road surfaces during the rotation and movement of the support wheels. In practice, the support wheels also have a shock-absorbing function, and both the drive wheels and the support wheels have independent shock-absorbing capabilities, which can further improve stability and enhance adaptability to complex terrain. Specifically, the shock-absorbing structure includes but is not limited to shock absorbers. This eliminates vibration caused by the road surface and improves driving stability.

[0075] In some embodiments, as Figure 1 and Figure 2 As shown, a mounting hole is provided in the middle of the frame 10, and the power supply assembly 20 is installed in the mounting hole. Part of the power supply assembly 20 is located on the side of the frame 10 close to the drive wheel assembly 31, and part of the power supply assembly 20 is located on the side of the frame 10 away from the drive wheel assembly 31. This arrangement can effectively lower the center of gravity of the power supply assembly 20. Moreover, for a mobile platform, the power supply assembly 20 is relatively heavy and has the greatest impact on the center of gravity of the mobile platform. Therefore, by lowering the center of gravity of the power supply assembly 20, the stability of the mobile platform is improved, thereby ensuring that it will not fall or collapse even when traveling on uneven roads.

[0076] In some embodiments, as Figure 4 and Figure 5As shown, a lower baffle 11 is further provided on the side of the frame 10 close to the driving wheel group 31. A clearance hole 110 is provided on the lower baffle 11 corresponding to the position of the driving wheel group 31 and the supporting wheel group 32. The lower baffle 11 is used to prevent external contaminants from entering the interior of the mobile platform. In application, an anti-collision strip 111 is provided on the side of the lower baffle 11 away from the frame 10. Since the lower baffle 11 is relatively close to the ground, the lower baffle 11 is the first to collide when encountering an obstacle. In order to protect the lower baffle 11, an anti-collision strip 111 is added. On the one hand, it acts as a buffer, and on the other hand, it can also prevent the lower baffle 11 from being damaged. Specifically, the anti-collision strip 111 is set at the front end of the lower baffle 11. It should be noted that the left and right directions above refer to the X direction in the figure, and the front and back directions (the front end or rear end refers to the Y direction). The above is only for the convenience of understanding the technical solution of the embodiment of the present application, and should not be understood as limiting the scope of protection of the embodiment itself.

[0077] In some embodiments, as Figures 4 to 7 As shown, the side of the frame 10 away from the driving wheel group 31 is also provided with an upper cover 12, and the side of the upper cover 12 away from the driving wheel group 31 is also provided with a connecting member 121, which is used to connect to external equipment; in application, the connecting member 121 includes but is not limited to slide rails, fastening screws, mounting holes, etc., which can be connected to external equipment to further improve the applicability of the intelligent robot.

[0078] In use, a first installation space 100 is formed between the frame 10 and the lower baffle 11. The first installation space 100 is used for installing the driving wheel group 31, the supporting wheel group 32, and the shock absorbing assembly 40. A second installation space 101 is formed between the frame 10 and the upper cover 12. The second installation space 101 is used for installing the control module 80 and the electrical structure.

[0079] The first installation space 100 and the second installation space 101 are separated from each other to prevent external contaminants from entering the mobile platform and ensure that the internal components are not affected. By physically separating the electrical and motion components, the two modules can be prevented from interfering with each other, which also improves the overall spatial layout and space utilization of the mobile platform.

[0080] In some embodiments, as Figures 8 to 10 The mobile platform also includes a housing 13, which is connected to the upper cover 12, the frame 10, and the lower baffle 11. The housing 13 encloses the first installation space 100 and the second installation space 101. This effectively improves the aesthetics and the physical protection of the mobile platform. The housing 13 also provides a mounting platform for some sensors.

[0081] The side of the housing 13 near the front end of the mobile platform is recessed toward the interior of the mobile platform, forming a heat dissipation space 130. Within this heat dissipation space 130, the housing 13 is provided with a plurality of heat dissipation holes 131, which connect the second installation space 101 and the clearance space. Heat dissipation space 130 also serves as a clearance space, allowing the mobile platform's internal components to extend for user operation. The presence of heat dissipation holes 131 effectively improves heat dissipation for the electrical components within the second installation space 101.

[0082] In some embodiments, as Figures 4 to 7 As shown, connecting columns 14 are provided between the lower baffle 11 and the frame 10. The connecting columns 14 are respectively arranged on both sides of the frame 10 to improve the stability of the frame 10 and facilitate the connection between the lower baffle 11 and the upper cover 12. A fixing bar 15 is also provided on the side of the frame 10 away from the lower baffle 11. The two ends of the connecting column 14 are respectively connected to the lower baffle 11 and the fixing bar 15, and the middle part of the connecting column 14 is connected to the frame 10. Furthermore, the connecting column 14 is connected to the outer shell 13, and the fixing bar 15 is welded to the outer shell 13. In use, multiple support columns are provided between the upper cover 12 and the frame 10, and multiple support columns are also provided between the frame 10 and the baffle to connect and fix the frame 10, the upper cover 12, and the lower baffle 11.

[0083] In some embodiments, the fixing bar 15 is a welded component, provided on both the upper and lower portions of the housing 13. The fixing bar 15 is welded to the housing 13 as a single unit, facilitating connection to the load platform and the lower baffle 11. In use, the housing 13 comprises a front shell, a rear shell, and a top shell. The front and rear shells respectively enclose the circumference of the frame 10, covering the front and rear ends of the mobile platform, both physically protecting the internal components and enhancing the aesthetics. The top cover 12 is connected to the fixing bar 15, enclosing and covering the top of the mobile platform.

[0084] In some embodiments, as Figure 5 、 Figures 8 to 10 As shown, the mobile platform further includes a sensor assembly 50, an expansion interface assembly 60, and a junction box 61. The sensor assembly 50 and the expansion interface assembly 60 are distributed at the front and rear ends of the mobile platform. The junction box 61 is located on the frame 10 and below the expansion interface assembly 60.

[0085] The sensor assembly 50 includes a distance measuring sensor 51 , an anti-collision sensor 52 and an anti-falling sensor 53 distributed along the circumference of the mobile platform. The anti-falling sensor 53 is arranged at the bottom of the mobile platform.

[0086] In application, the anti-fall sensors 53 are distributed on the driving wheel set 31 and the supporting wheel set 32 ​​to detect the distance between the wheels and the ground in real time to prevent the wheels from stepping on air, thereby playing a role in anti-falling.

[0087] In practice, expansion interface assembly 60 generally refers to the portion of a hardware device or software system used to add functionality or connect to other devices. This includes, but is not limited to, the following: PCI card slots, an early standard for expansion slots, used to install various cards, such as sound cards and network cards; USB ports, used to connect to various external devices, such as keyboards, mice, and printers; and high-speed data transfer interfaces, capable of connecting monitors, hard drives, and other peripherals.

[0088] In use, the junction box 61 is a device used to connect wires. It can protect the wire connections from the influence of the external environment (such as moisture, dust, etc.), preventing the occurrence of wire short circuits or electric shock accidents. When the wiring needs to be inspected or repaired, the junction box can be easily opened. In some complex circuit systems, the junction box can be used to centrally manage multiple lines, making the line layout clearer and more orderly, and reducing the possibility of incorrect connections. The space inside the junction box can accommodate various types of connectors and adapters, so that wires of different specifications can be easily connected together. By using a junction box, it can be ensured that all wire connections are completed in a closed and safe environment, effectively avoiding potential safety hazards.

[0089] The mobile platform also includes a charging diode, which prevents simultaneous discharge during charging, enhancing safety. The battery's output is located within a junction box 61, which supports integrated capabilities such as manual charging, automatic recharging, and discharging, making wiring safer and more convenient.

[0090] In some embodiments, as Figures 8 to 10 As shown, a visual sensing module 70 is provided at the front end of the mobile platform. The visual sensing module 70 includes: a mounting frame 71, a camera 72 and an ultrasonic radar 73;

[0091] The camera 72 is mounted on the mounting frame 71 and faces the front end of the mobile platform. The camera 72 is used to capture three-dimensional information in the environment and accurately measure the distance and size of objects.

[0092] The ultrasonic radar 73 is mounted on the mounting bracket 71 and measures distance by emitting ultrasonic waves and receiving reflected waves.

[0093] In practice, the mounting bracket 71 can be mounted on the frame 10. In this embodiment, the mounting bracket 71 is located at the front end of the housing 13.
