Utility Model Content

[0003] The main purpose of this invention is to propose a chassis structure, a robot chassis, and a unibody robot, aiming to improve the stability and reliability of the unibody robot chassis.

[0004] To achieve the above objectives, the present invention proposes a chassis structure including a chassis, a shock absorber, a connector, and a hub motor. The shock absorber is supported and connected to the bottom of one end of the chassis along its length. The two ends of the connector along its length are respectively connected to the other end of the chassis along its length and the end of the shock absorber away from the chassis. The output shaft of the hub motor is connected to the connector and is located between the connector and the chassis and the connection point of the shock absorber.

[0005] In one embodiment, the chassis includes a battery mounting plate, a first support member, and a second support member. The first support member includes two members, which are respectively disposed at the bottom of both sides of the battery mounting plate in the width direction and extend along the length direction of the battery mounting plate. A second support member is respectively disposed at the bottom of both ends of the extension direction of each first support member. The shock absorber is connected to the first support member, and the connector is connected to the second support member. The battery mounting plate has a mounting groove for accommodating the battery.

[0006] In one embodiment, both the first support member and the second support member are U-shaped profiles with downward openings. A caster pad is connected to the bottom of each second support member, and the caster pad is used to connect a swivel wheel.

[0007] In one embodiment, the chassis structure further includes a radar mounting plate and a first lidar, with both ends of the radar mounting plate connected to a first support member, and the first lidar mounted on the radar mounting plate.

[0008] This utility model also proposes a robot chassis, which includes the chassis structure, outer shell assembly, and base plate assembly described above. The outer shell assembly includes a shell and a top mounting plate, with the top mounting plate disposed above the shell. The base plate assembly includes a base plate, caster fixing cylinders, caster fixing plates, and a power module. The shell and the base plate enclose a mounting cavity, and the chassis structure is disposed within the mounting cavity. Each caster fixing cylinder is circumferentially disposed on the base plate, and each caster fixing plate is correspondingly connected to a caster fixing cylinder. Each caster fixing plate is correspondingly connected to a caster pad, and the power module is connected to the base plate.

[0009] In one embodiment, the robot chassis further includes an electronic control panel and a battery. The battery is disposed in the mounting slot, and the two ends of the electronic control panel are respectively connected to the tops of the two first support members. The electronic control panel is located above the battery.

[0010] In one embodiment, the robot chassis further includes a charging assembly, which includes a charging mounting bracket, a charging contact plate, a charging contact piece, and an electromagnet. The charging mounting bracket is connected to the base plate, the charging contact plate and the electromagnet are disposed on the charging mounting bracket, and the charging contact piece is connected to the charging contact plate.

[0011] In one embodiment, the robot chassis further includes a navigation component, which includes a second lidar, a camera mounting plate, and a camera.

[0013] This utility model also proposes a body-type robot, which includes the robot chassis described above.

[0014] This utility model proposes a chassis structure including a chassis, shock absorbers, connecting parts, and hub motors. The shock absorbers are supported and connected to the bottom of one end of the chassis along its length. The connecting parts are connected to the other end of the chassis along its length and the end of the shock absorbers furthest from the chassis. This creates a triangular support structure, improving the overall stability of the chassis. The shock absorbers provide initial cushioning against external impacts, and the connecting parts evenly distribute the remaining impact force across the entire chassis structure, effectively protecting other critical components such as the battery and motor from damage due to excessive vibration. Simultaneously, the output shaft of the hub motor is connected to the connecting parts and located between the connecting parts and the chassis and shock absorbers. This design allows the hub motor's power to directly act on the connecting parts, thereby driving the movement of the entire chassis structure. This not only improves power transmission efficiency but also, because the hub motor is located between key connecting parts, enhances the compactness and integrity of the entire chassis structure, reducing swaying and deformation during power transmission and improving the vehicle's stability and handling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] The chassis of a posterior robot is a crucial component, acting as its "legs" and providing fundamental support for its movement and motion. With the continuous development of artificial intelligence and robotics, the application prospects of posterior robots in various fields are expanding, leading to increasingly higher demands on their chassis technology. The stability and reliability of the chassis structure directly affect the performance of the posterior robot. Improving the stability of the chassis structure to ensure stable operation of the posterior robot in various complex terrains remains a challenge that requires further investigation.

[0033] To solve the above problems, please refer to... Figures 1 to 10 This utility model proposes a chassis structure 10, including a chassis 1, a shock absorber 2, a connector 3, and a hub motor 4. The shock absorber 2 is supported and connected to the bottom of one end of the chassis 1 along its length. The two ends of the connector 3 along its length are respectively connected to the other end of the chassis 1 along its length and the end of the shock absorber 2 away from the chassis 1. The output shaft of the hub motor 4 is connected to the connector 3 and is located between the connector 3 and the chassis 1 and the shock absorber 2.

[0034] The present invention provides a chassis structure 10, comprising a chassis 1, a shock absorber 2, a connector 3, and a hub motor 4. The shock absorber 2 is supported and connected to the bottom of one end of the chassis 1 along its length. The connector 3 is connected to the other end of the chassis 1 along its length and the end of the shock absorber 2 away from the chassis 1. Thus, the chassis 1, the shock absorber 2, and the connector 3 together form a triangular support structure, which improves the overall stability of the chassis structure 10. The shock absorber 2 provides initial buffering against external impacts, and the connector 3 evenly transmits the remaining impact force to the entire chassis structure 10, thereby effectively protecting other key components on the chassis 1, such as the battery 50 and electrical components, from damage due to excessive vibration. Meanwhile, the output shaft of the hub motor 4 is connected to the connector 3 and is located between the connector 3 and the chassis 1 and the shock absorber 2. This design allows the power of the hub motor 4 to be directly applied to the connector 3, thereby driving the movement of the entire chassis structure 10. This not only improves the efficiency of power transmission, but also, because the hub motor 4 is located between key connection points, it can enhance the compactness and integrity of the entire chassis structure 10 to a certain extent, reduce shaking and deformation during power transmission, and improve the stability and handling of the whole machine.

[0035] In an optional embodiment, for easier implementation of the support effect of the chassis structure 10, please refer to... Figure 7 and Figure 8 The chassis 1 includes a battery mounting plate 11, a first support member 12, and a second support member 13. The first support member 12 includes two members, which are respectively located at the bottom of both sides of the battery mounting plate 11 in the width direction and extend along the length direction of the battery mounting plate 11. A second support member 13 is provided at the bottom of both ends of the extension direction of each first support member 12. The shock absorber 2 is connected to the first support member 12, and the connector 3 is connected to the second support member 13. The battery mounting plate 11 has a mounting groove for accommodating the battery 50.

[0036] The battery mounting plate 11 has mounting grooves for accommodating the battery 50, providing a stable and safe mounting space for the battery 50. This ensures the stability of the battery 50 during vehicle operation and prevents displacement or shaking due to vibration, thereby guaranteeing the stability of the vehicle's power supply. Two first support members 12 are respectively located at the bottom of both sides of the battery mounting plate 11 in the width direction and extend along the length direction of the battery mounting plate 11. This layout allows the first support members 12 to effectively disperse the pressure and impact force on the battery mounting plate 11, evenly transmitting these forces to other parts of the chassis 1, enhancing the load-bearing capacity and impact resistance of the entire chassis 1. Second support members 13 are respectively provided at the bottom of both ends of the extension direction of each first support member 12. The shock absorber 2 is connected to the first support member 12, and the connecting member 3 is connected to the second support member 13. This layered support structure allows the shock absorber 2 and the connecting member 3 to function independently while cooperating with each other, further improving the stability and adaptability of the chassis 1 when facing impacts of different directions and degrees. For example, when the robot encounters a bumpy road during its movement, the shock absorber 2 can absorb the impact from the road in time, while the connecting piece 3 can stably transfer the force transmitted by the shock absorber 2 to the second support piece 13, which then distributes it to the entire chassis 1, thereby ensuring the stability of the robot's movement.

[0037] In an optional embodiment, to ensure the overall strength of the chassis structure 10, please refer to... Figures 5 to 8 The first support member 12 and the second support member 13 are both U-shaped and both have their openings facing downwards. The bottom of each second support member 13 is connected to a caster pad 14, which is used to connect the caster wheel 306.

[0038] The U-shaped profile possesses high strength and rigidity, enabling it to withstand significant pressure and impact, and helps reduce the overall weight of the chassis structure 10, thus improving vehicle handling performance. Furthermore, each second support member 13 has a caster pad 14 connected to its bottom, which connects to the swivel caster 306. This design not only provides a stable mounting base for the swivel caster 306, but also, because the caster pad 14 is connected to the second support member 13, which in turn is tightly connected to the entire chassis structure 10, the swivel caster 306 provides greater stability and reliability in supporting vehicle weight and offering mobility. When the vehicle needs to turn or move in complex terrain, the swivel caster 306 can rotate flexibly, and the secure connection between the caster pad 14 and the second support member 13 ensures that the swivel caster 306 will not loosen or shift during rotation, thereby improving vehicle handling stability and safety.

[0039] In an optional embodiment, for ease of navigation of the chassis structure 10, please refer to... Figure 7 and Figure 8 The chassis structure 10 also includes a radar mounting plate 5 and a first lidar 6. The two ends of the radar mounting plate 5 are respectively connected to a first support member 12, and the first lidar 6 is mounted on the radar mounting plate 5.

[0040] The radar mounting plate 5 is connected to a first support member 12 at each end. This arrangement allows the radar mounting plate 5 to be stably fixed to the chassis 1, preventing shaking due to vibration or impact during the robot's movement and ensuring the stability of the first lidar 6. The first lidar 6 is mounted on the radar mounting plate 5. Since the radar mounting plate 5 is connected to the first support member 12, and the first support member 12 is tightly connected to the entire chassis structure 10, the first lidar 6 can achieve a relatively high mounting position, thereby expanding its detection range and enabling more comprehensive perception of objects and obstacles in the robot's surrounding environment. This helps improve the vehicle's autonomous driving ability in complex environments. For example, in narrow passages or crowded places, the first lidar 6 can promptly detect surrounding obstacles and feed the information back to the robot's control system, allowing the robot to adjust its driving route in time and avoid collisions. Meanwhile, mounting the lidar on the lidar mounting plate 5 also facilitates its maintenance and upgrades. The lidar mounting plate 5 provides a relatively independent and easily accessible mounting platform, allowing maintenance personnel to easily inspect, clean, or replace parts to ensure it is always in good working order.

[0041] This utility model also proposes a robot chassis 100, which includes a chassis structure 10, a shell assembly 20, and a base plate assembly 30. The shell assembly 20 includes a shell 201 and a top mounting plate 202, with the top mounting plate 202 disposed above the shell 201. The base plate assembly 30 includes a base plate 301, caster fixing cylinders 302, caster fixing plates 303, and a power module 304. The shell 201 and the base plate 301 enclose a mounting cavity, and the chassis structure 10 is disposed within the mounting cavity. Each caster fixing cylinder 302 is circumferentially disposed on the base plate 301, and each caster fixing plate 303 is correspondingly connected to a caster fixing cylinder 302. Each caster fixing plate 303 is correspondingly connected to a caster pad 14, and the power module 304 is connected to the base plate 301. The specific structure of the chassis structure 10 is as described in the above embodiments. Since this robot chassis 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here. Please refer to... Figures 1 to 4 ,as well as Figure 9The outer shell assembly 20 consists of a shell 201 and a top mounting plate 202. The top mounting plate 202 is located above the shell 201. This design provides a stable mounting platform for the robot's upper structure, which can be used to install various sensors, cameras 703, or other functional modules, thereby expanding the robot's functionality. The base plate assembly 30 includes a base plate 301, caster fixing cylinders 302, caster fixing plates 303, and a power module 304. The shell 201 and the base plate 301 enclose a mounting cavity, and the chassis structure 10 is located within the mounting cavity. This enclosed structural design effectively protects the chassis structure 10 and other internal components from external environmental influences, such as dust, moisture, and collisions, helping to extend the service life of the robot. Each caster fixing cylinder 302 is circumferentially distributed on the base plate 301 and correspondingly connected to the caster fixing plate 303 and the caster pad 14, so that the casters 306 can be evenly distributed around the base plate 301, improving the support stability and movement balance of the robot. The power module 304 is connected to the base plate 301, providing power to the entire embodied robot. Located on the base plate 301, the power module 304 helps lower the robot's center of gravity, improving its stability during movement and reducing the risk of tipping over. Furthermore, the base plate 301 is equipped with a drop ultrasonic sensor 305 to prevent the robot chassis 100 from falling when encountering steps, steep slopes, or potholes. When the robot reaches the edge of a step, the drop ultrasonic sensor 305 uses ultrasound to measure the distance between the robot chassis 100 and the ground. If this distance exceeds a set limit, a signal is sent to the controller, which then issues a steering command to change the robot chassis 100's direction of travel, thus preventing falls. This integrated chassis 1 design arranges all components in a compact space, optimizing the overall structure of the embodied robot and facilitating its installation, debugging, and maintenance, thereby improving the robot's reliability and maintainability.

[0042] In an optional embodiment, for ease of movement of the robot chassis 100, please refer to... Figures 1 to 4 The robot chassis 100 also includes an electronic control panel 40 and a battery 50. The battery 50 is located in the mounting slot, and the two ends of the electronic control panel 40 are respectively connected to the tops of the two first support members 12. The electronic control panel 40 is located above the battery 50.

[0043] The battery 50 is housed in a mounting slot located on the battery mounting plate 11, allowing it to be stably positioned in the center of the chassis 1, close to the robot's center of gravity. This helps balance the robot's weight distribution, improving its stability and maneuverability during movement. The control panel 40 is connected at both ends to the top of the battery mounting plate 11 and is positioned above the battery 50. This facilitates connection and communication with various sensors and actuators on the upper part of the robot, while also preventing direct contact between the control panel 40 and the battery 50, reducing the risk of damage to the control panel 40 due to battery leakage or other unforeseen circumstances. The control panel 40 is used to configure the robot's electrical control components. Its stable mounting position and favorable electrical connection environment ensure accurate processing of various commands and signals by the robot, enabling precise control over its motion, perception, and execution. Furthermore, mounting the control panel 40 on top of the battery mounting plate 11, and utilizing the support structure of the battery mounting plate 11 to support the control panel 40, can reduce the impact of vibrations on the control panel 40 during the robot's movement, thus improving the reliability of the control panel 40's operation. This layout also facilitates heat dissipation for the control panel 40, as its location above the battery 50 and in a relatively open position allows for air circulation, carrying away the heat generated during operation and extending the lifespan of the control panel 40, thereby ensuring the long-term stable operation of the robot.

[0044] In an optional embodiment, for ease of implementing charging and battery life for the robot chassis 100, please refer to... Figure 4 , Figure 5 as well as Figure 10 The robot chassis 100 also includes a charging component 60, which includes a charging fixture 601, a charging contact plate 602, a charging contact piece 603, and an electromagnet 604. The charging fixture 601 is connected to the base plate 301, the charging contact plate and the electromagnet 604 are located on the charging fixture 601, and the charging contact piece 603 is connected to the charging contact plate 602.

[0045] The charging mounting bracket 601 is connected to the base plate 301, providing a stable mounting foundation for the entire charging assembly 60. This ensures that the charging assembly 60 will not shake or shift during the movement of the robot chassis 100, thus guaranteeing the stability of the charging process. The charging contact plate 602 and electromagnet 604 are mounted on the charging mounting bracket 601. The charging contact piece 603 is connected to the charging contact plate 602, allowing the charging contact piece 603 to accurately dock with the charging interface of the external charging device. When the robot needs charging, the electromagnet 604 can attract the charging interface of the external charging device, making it tightly contact the charging contact piece 603, thereby achieving a reliable electrical connection and ensuring that the charging current can be stably transmitted to the battery 50 inside the robot. The design of the charging assembly 60 not only improves the charging efficiency and reliability but also enables automatic charging. Upon receiving a charging command, the robot can automatically move to the charging area and dock with the charging device through the electromagnet 604, reducing manual intervention and improving the autonomy and convenience of the robot's operation. Meanwhile, the secure installation of the charging bracket 601 can also protect the charging component 60 from external collisions and damage, extend its service life, and ensure that the robot can charge normally and efficiently, thereby maintaining its long-term stable operation.

[0046] In an optional embodiment, to further improve the navigation and obstacle avoidance performance of the robot chassis 100, please refer to... Figure 3 , Figure 4 as well as Figure 6 The robot chassis 100 also includes a navigation component 70, which includes a first lidar 6, a second lidar 701, a camera mounting plate 702, and a camera 703. The camera mounting plate 702 is connected to the end of the housing 201 away from the charging component 60, and the second lidar 701 and the camera 703 are spaced apart on the camera mounting plate 702.

[0047] The camera mounting plate 702 is connected to the end of the housing 201 furthest from the charging assembly 60, that is, mounted in front of the robot chassis 100. This provides the camera 703 with a relatively wide field of view, enabling it to better capture image information of the environment in front of and around the robot chassis 100, providing more comprehensive visual data for the robot's visual navigation and obstacle recognition. The second LiDAR 701 and the camera 703 are spaced apart on the camera mounting plate 702. This spaced arrangement helps avoid mutual interference between the LiDAR and the camera 703, ensuring that both can independently acquire accurate environmental information. The LiDAR measures distance and detects obstacles by emitting and receiving laser beams, while the camera 703 identifies features such as the shape, color, and texture of objects by capturing images. This spaced arrangement prevents the LiDAR's laser beam from interfering with the imaging of the camera 703, and also avoids the camera 703's flash or other light sources affecting the LiDAR's measurement results. The first LiDAR 6 is mounted on the radar mounting plate 5, located at the top of the robot. It provides a higher-angle environmental perception, complementing the low-angle perception of the camera 703 and the second LiDAR 701 to form a multi-dimensional environmental perception system. This improves the navigation accuracy and obstacle avoidance capabilities of the embodied robot in complex environments. This multi-layered, multi-angle navigation component layout enables the embodied robot to have a more comprehensive understanding of its surroundings, promptly detect and avoid obstacles, accurately plan its path, and achieve efficient and safe autonomous navigation.

[0048] In an optional embodiment, to facilitate human-machine interaction between the user and the robot chassis 100, please refer to... Figure 1 and Figure 2 The side wall of the housing 201 is also provided with an operation panel, which includes a waterproof socket 2011, a reset button 2012 and an emergency button 2013.

[0049] This design provides the robot chassis 100 with a convenient human-machine interface, facilitating operator control and management. The waterproof socket 2011 allows the robot chassis 100 to safely use external power devices, such as chargers and maintenance tools, in humid environments or places requiring water cleaning, without worrying about short circuits or other electrical faults caused by moisture entering the socket. This enhances the adaptability and reliability of the robot chassis 100 in various harsh environments. The reset button 2012 allows operators to quickly reset the robot chassis 100 in case of system failure or crashes, restarting the system and restoring it to normal operation. This reduces downtime caused by system failures and improves the availability and efficiency of the robot chassis 100. The emergency button 2013 is designed to prevent accidents and ensure the safety of personnel and equipment in case of emergencies such as impending collisions, getting stuck in dangerous areas, or other situations that may endanger personnel or equipment. Operators can quickly press the emergency button 2013 to immediately stop all movements of the robot chassis 100, effectively preventing accidents and ensuring the safety of personnel and equipment. All these functions on the control panel are concentrated in an easily observable and accessible location, allowing operators to operate quickly and accurately when needed, eliminating the need to search for multiple scattered control components on the robot chassis 100, thus improving operational convenience and emergency response speed.

[0050] This utility model also proposes a body-like robot, which includes a robot chassis 100. The specific structure of the robot chassis 100 is as described in the above embodiments. Since this body-like robot adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Other communication modules, sensor modules, or robotic arms can be installed and connected on the top mounting plate 202 so that the body-like robot can meet different usage scenarios and needs. The body-like robot, using the above-described robot chassis 100, has high stability and reliability and can adapt to various complex environments and task requirements. The various components included in the chassis structure 10, such as the shock absorber 2, hub motor 4, battery fixing plate 11, support components, radar mounting plate 5, lidar, casters, etc., together provide a solid foundation for the body-like robot's movement, perception, control, and power supply. The rational layout of the shock absorber 2 and support components ensures the stability of the embodied robot during movement, avoiding structural damage and equipment failure caused by vibration and impact. The efficient power transmission and flexible wheel design of the hub motor 4 enable the embodied robot to respond quickly and accurately to control commands, achieving flexible movement. The multi-dimensional layout of sensing components such as LiDAR and camera 703 gives the embodied robot strong environmental perception capabilities, enabling it to autonomously navigate, avoid obstacles, and perform tasks in complex environments. The design of the battery mounting plate 11 and power module 304 ensures that the embodied robot has sufficient power support, extending its working time. The various control elements on the operation panel facilitate the operator's management and emergency operation of the embodied robot. This allows the embodied robot to play an important role in various fields such as industry, logistics, service, and rescue, such as material handling in factories, inventory management in warehouses, providing guidance services in public places, or conducting search and rescue operations at disaster sites. Its highly integrated and modular design also facilitates functional expansion and customization according to different task requirements, further enhancing the applicability and flexibility of embodied robots and providing strong technical support for the widespread application and development of embodied robots.
