[0028] This utility model proposes a magnetic charging base for a robot, referring to... Figures 1 to 4 The magnetic charging base of the robot includes a base body 11 mounted on a base plate 12. The base body 11 has a protrusion 110 extending above the top surface of the body. At the front opening of the protrusion 110, there is a magnetic interface 111 adapted to the magnetic charging port 24 of the robot 20. The distance D0 between the left and right sides of the base body is less than or equal to the inner distance between the left support component 21 and the right support component 22 of the robot 20. The first gap height D1 between the top surface of the body and the base plate 12 is within the adjustable ground height range of the hip 23 of the robot 20 connecting the left support component 21 and the right support component 22. The second gap height D2 between the magnetic interface 111 and the base plate 12 is within the adjustable ground height range of the magnetic charging port 24. The base body 11 has a built-in charging circuit, and the output interface of the charging circuit is electrically connected to the magnetic interface 111.

[0029] In this embodiment, the base plate 12 is the foundation of the base, providing stable support. The base plate 12 can be made of a high-strength, non-slip material (such as rubber or engineering plastics) to ensure the stability of the base on different surfaces.

[0030] The base body 11 is set on the base plate 12 and is the core part of the charging base, supporting the protrusion 110, the magnetic interface 111 and the charging circuit.

[0031] The base body 11 is also provided with a protrusion 110 that extends above the top surface of the body. The protrusion 110 is the part of the base body 11 that extends upwards and is used to install the magnetic interface 111 and ensure that the magnetic charging port 24 of the robot 20 can be smoothly connected to the base.

[0032] The protrusion 110 has a magnetic interface 111 at its front opening, which is adapted to the magnetic charging port 24 of the robot 20. The magnetic interface 111 contains a strong magnet and electrical contacts. The magnet is responsible for attracting and fixing the magnetic charging port 24 of the robot 20, while the electrical contacts are responsible for power transmission.

[0033] Optionally, the electrical contacts are designed with wear-resistant and corrosion-resistant materials to meet frequent charging needs. The shape and position of the contacts are perfectly aligned with the contact shape and position corresponding to the magnetic charging port 24 of the robot 20.

[0034] The distance D0 between the left and right sides of the base body is designed to be less than or equal to the inner distance between the left support component 21 and the right support component 22 of the robot 20. This design ensures that the robot 20 will not shift its position when placed due to the base being too narrow or too wide, thus improving the stability of charging.

[0035] The first gap height D1 between the top surface of the main body and the base body 11 is designed within the adjustable ground height range of the hip 23 of the robot 20 connecting the left support component 21 and the right support component 22. That is, the first gap height D1 should ensure that when the robot 20 is placed on the base, its chassis or hip 23 can land stably on the top surface of the base body.

[0036] The second gap height D2 between the magnetic interface 111 and the base plate 12 is designed within the adjustable ground height range of the magnetic charging port 24. That is, when the chassis or hip 23 of the robot 20 can be stably placed on the top surface of the main body of the base, the position of the magnetic interface 111 should be able to accurately align with and contact the magnetic charging port 24 of the robot 20.

[0037] The robot 20 has a hip 23 for connecting the left support component 21 and the right support component 22, which are in contact with the ground. The magnetic charging port 24 can be located above the hip 23. The support components can be equipped with corresponding connecting joints and sub-components. By adjusting the combined angle of the joints and sub-components, the overall height of the robot 20 can be adjusted, which in turn adjusts the height of the hip 23 and the magnetic charging port 24 from the ground.

[0038] Taking a wheeled robot as an example, the chassis of a wheeled robot typically consists of wheels on the left and right sides and corresponding support structures. These support structures can include retractable support arms, adjustable axle mechanisms, connecting shafts, etc. During charging, the wheeled robot can adjust the support structure to match the height of the magnetic charging port 24 with the height of the magnetic interface 111 on the charging base.

[0039] Taking humanoid robots as an example, the hips are a key part connecting the body and the leg support components. The legs are usually composed of multiple joints, such as the hip joint and knee joint, which can be adjusted by motors or hydraulic devices; each joint of the leg is equipped with a flexible adjustment mechanism, allowing the robot to adjust the length or angle of the leg, thereby changing the robot's overall height.

[0040] By adjusting the bending or extension angle of the leg joints, the length of the legs can be changed, thereby adjusting the overall ground clearance of the robot 20. Changes in leg length directly affect the ground clearance of the hip joint 23, as the hip joint 23 is the basic support point for the legs. The magnetic charging port 24 is typically located in the torso above the hip joint 23. When the leg joints are adjusted, the ground clearance of the torso and the charging port will also change accordingly.

[0041] For example, when the robot 20 needs to walk on uneven ground, it can maintain a stable height off the ground by adjusting the angle of its leg joints. When charging, the robot 20 adjusts its knee and hip joints from a standing position to a lower sitting position so that it can dock with the magnetic interface 111 on the charging base.

[0042] The base body 11 integrates a charging circuit. The charging circuit is responsible for converting the input DC power into DC power suitable for the robot's battery. The output interface of the charging circuit is directly connected to the magnetic interface 111. When the magnetic charging port 24 of the robot 20 is connected to the magnetic interface 111 of the charging base, the robot 20 can be charged through the magnetic interface 111.

[0043] By placing the robot 20 in the corresponding position on the base, the magnetic interface 111 will automatically attach and connect, and the charging process will begin.

[0044] In one embodiment, by integrating a charging circuit inside the base body 11 and achieving power transmission through a magnetic interface 111, physical plugging and unplugging are eliminated. This reduces cable tangling and interface wear, avoids equipment damage or safety hazards caused by improper plugging and unplugging, and enables a highly efficient and automated robot charging process. Whether charging automatically or manually, magnetic technology simplifies the charging operation and improves charging efficiency.

[0045] In one embodiment, based on the above embodiments, referring to Figure 5 The charging circuit includes a TYPE-C input terminal, a fast charging chip module, an anti-sparking module, an output interface, and a main control chip module; wherein, the TYPE-C input terminal is electrically connected to the output interface via the fast charging chip module and the anti-sparking module, and the TYPE-C input terminal is also electrically connected to the main control chip module via the fast charging chip module; the main control chip module is also electrically connected to the control terminal of the output interface.

[0046] In this embodiment, the TYPE-C input terminal serves as the power input interface for the charging circuit, supporting power input via the TYPE-C interface. The TYPE-C interface offers advantages such as reversible plugging and high power transmission capabilities (e.g., support for PD fast charging protocols), making it suitable for the needs of modern charging devices.

[0047] The fast charging chip module is responsible for rapidly charging the input power, improving charging efficiency. The input terminal of the fast charging chip module connects to the TYPE-C input terminal to receive power input; the output terminal of the fast charging chip module connects to the output interface via an anti-sparking module.

[0048] The fast charging chip module is responsible for managing the fast charging operation, including voltage and current regulation and the implementation of fast charging protocols (such as PD and QC). The fast charging chip module connects to the TYPE-C input terminal to obtain power input information and drive power. It also connects electrically to the main control chip module, providing fast charging status information and drive power to the main control chip module, or receiving control signals from the main control chip module to adjust its operating parameters.

[0049] The anti-sparking module is used to prevent electric sparks from being generated when plugging and unplugging the charging interface, protecting the circuit and equipment safety. The input terminal of the anti-sparking module is connected to the fast-charging chip module to receive power processed by fast charging; the output terminal of the anti-sparking module is connected to the output interface to output the safely processed power to the magnetic interface 111.

[0050] The output interface is used to output the processed power to the magnetic interface 111 to charge the robot 20. The input end of the output interface receives power through an anti-sparking module; the control end of the output interface is connected to the main control chip module and receives control signals from the main control chip module.

[0051] The main control chip module, as the core control unit of the entire charging circuit, is responsible for coordinating the work of various modules, including fast charging management, power output control, and fault detection. Specifically, the input terminal of the main control chip module connects to the fast charging chip module to obtain fast charging status information and drive power; the output terminal of the main control chip module connects to the control terminal of the output interface to control power output or internal energy storage.

[0052] In addition, the main control chip module can also be responsible for safety functions such as temperature monitoring, overvoltage protection, and short circuit protection.

[0053] Charging circuit working process:

[0054] External power enters the charging circuit through the TYPE-C input terminal; the power is processed by the fast charging chip module to achieve fast charging; the power passes through the anti-sparking module to ensure safety during insertion and removal; the processed power is transmitted to the magnetic interface 111 through the output interface to charge the robot 20. The main control chip module monitors and manages the entire charging process in real time to ensure charging safety and efficiency.

[0055] The TYPE-C input terminal supports a maximum power output of 20V and 3.25A; the magnetic connector 111 supports a maximum power output of 12.6V and 5A.

[0056] In one embodiment, the provided charging circuit supports fast charging protocols, shortening charging time, and provides multiple protections through an anti-sparking module and a main control chip module. Intelligent control is achieved based on the main control chip module, improving charging efficiency and reliability. The TYPE-C interface supports multiple power inputs, offering strong adaptability. This charging circuit design is ideal for robotic devices requiring efficient and safe charging, meeting the high charging performance requirements of modern intelligent devices.

[0057] In one embodiment, based on the above embodiments, referring to Figure 5 The charging circuit also includes a battery terminal, which is electrically connected to the output interface.

[0058] In this embodiment, when the external power supply is disconnected, the battery can provide power to the robot 20 or other devices. The external power supply charges the battery through a charging circuit, and the battery can store electrical energy for later use.

[0059] When the battery is charging, the external power supply enters the charging circuit through the TYPE-C input terminal. The main control chip module and the fast charging chip module perform fast charging on the power supply. Then, the power supply passes through the anti-sparking module to ensure safety before being transmitted to the magnetic interface 111 and the battery terminal through the output interface. At this time, the battery terminal can receive the power supply and store electrical energy.

[0060] After the external power supply is disconnected, the battery can power the robot 20 or other devices through the output interface.

[0061] When an external power source is connected, it prioritizes using the external power source while simultaneously charging the battery. When the external power source is disconnected, it automatically switches to battery power to ensure continuous operation of the device.

[0062] In one embodiment, both external power input and battery power supply modes are supported, improving the device's battery life and adaptability. The main control chip module monitors the power status in real time and automatically switches the power supply mode to ensure continuous device operation.

[0063] This charging circuit design is ideal for robotic devices that require long-term operation or cannot be continuously powered by an external power source. For example:

[0064] Service robots: They operate continuously in scenarios such as shopping malls and restaurants, powered by batteries.

[0065] Drones: In environments without power outlets, they complete tasks using power supplied by batteries.

[0066] Smart home devices: Support continued operation after power outages, enhancing the user experience;

[0067] By adding a battery, the charging circuit becomes more comprehensive, better meeting the robot's power supply and charging needs.

[0068] In one embodiment, based on the above embodiments, referring to Figure 5 The charging circuit also includes a charging status display module. The input terminal of the charging status display module is electrically connected to the main control chip module, and the output terminal of the charging status display module is electrically connected to the display unit 112 disposed on the base body 11.

[0069] In this embodiment, the charging status display module displays information such as charging status, battery level, and charging speed through the display unit 112.

[0070] The input terminal of the charging status display module is connected to the main control chip module to obtain charging status information and drive power; the output terminal of the charging status display module is connected to the display unit 112 to display relevant information and provide drive power.

[0071] The main control chip module monitors and manages parameters such as voltage, current, and temperature in real time during the charging process. It processes these parameters to determine the charging status (e.g., charging in progress, fully charged, fault).

[0072] The main control chip module sends the charging status information to the charging status display module, which converts the received information into a displayable format and displays it to the user through the display unit 112.

[0073] The charging status is displayed intuitively by the display unit 112, allowing users to understand the device's charging status in real time. Furthermore, in the event of an anomaly, the display unit 112 can display error codes or alarm messages to help users quickly diagnose the problem.

[0074] By providing visual feedback, users can enhance their sense of participation and control over the charging process, making it easier for them to adjust charging settings and optimize charging management based on the displayed information.

[0075] By adding a charging status display module and display unit 112, the functionality of the charging dock is further enhanced, providing users with a more convenient and safer charging experience.

[0076] In one embodiment, based on the above embodiments, referring to Figure 1 The display unit 112 is located on the front of the base body 11, and the front of the base body 11 is tilted upwards.

[0077] In this embodiment, the display unit 112 is located on the front of the base body 11, and the base body 11 is tilted upwards. The tilted design makes the display unit 112 face the user, allowing the user to easily view the charging status from a standing or sitting position.

[0078] In this way, the display unit 112 faces the user, providing intuitive visual feedback and enhancing the user experience. Users can easily view information such as charging status, battery level, and fault prompts without bending over or adjusting their viewing angle.

[0079] In one embodiment, based on the above embodiments, referring to Figure 1 The magnetic charging base has multiple parallel strip-shaped heat dissipation vents 14 at various intervals.

[0080] In this embodiment, heat dissipation vents are provided at multiple locations on the magnetic charging base, and each location has multiple parallel strip-shaped heat dissipation vents 14 spaced apart.

[0081] In this way, by increasing the airflow path, the heat dissipation effect can be improved; and by setting up multiple heat dissipation vents, it is ensured that the heat is evenly dissipated from all parts of the base, avoiding local hot spots and reducing the risk of failure due to overheating.

[0082] In one embodiment, based on the above embodiments, referring to Figure 1 and Figure 2 An upward-facing inclined surface 13 is provided on the front side of the base plate 12, where the base body 11 is not covered; the robot 20 is a wheeled robot 20, and both the left support component 21 and the right support component 22 of the robot 20 are provided with rollers.

[0083] In this embodiment, an upward-facing inclined surface 13 is provided on the front side of the base plate 12, where the base body 11 is not covered. The inclined surface 13 helps the robot 20 to enter the charging position more easily. The robot 20 slides along the inclined surface 13 using rollers, reducing resistance during entry. The inclined surface 13 provides a smooth transition, ensuring that the robot 20 smoothly enters the charging base from the ground.

[0084] The robot 20 is equipped with casters on both its left support component 21 and right support component 22, allowing it to move freely. The caster design enables the robot 20 to move flexibly on the ground, facilitating user operation.

[0085] This utility model further proposes a robot system, which includes a robot 20 and a magnetic charging base for the robot. The specific structure of the magnetic charging base for the robot is as described in the above embodiments.
