[0003] In related technologies, control boards and various sensors and actuators are generally connected using standardized electronic wires (such as UL3302 electronic wires). This connection method results in numerous and messy electronic wires, making it difficult to distinguish the electronic wires corresponding to sensors or actuators during maintenance, which greatly reduces maintenance efficiency.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0044] The control components of a cleaning robot are its core, including a control board, various sensors, and actuators. Based on data transmission rates, sensors can be broadly categorized into low-speed and high-speed sensors. Low-speed sensors, such as collision sensors and distance sensors, typically have data transmission rates between a few Kbps and several hundred Kbps. These sensors primarily detect simple environmental information around the cleaning robot, such as whether it has collided with obstacles or its approximate distance to surrounding objects. High-speed sensors, such as 3D time-of-flight sensors and tri-color cameras, generally transmit data at Mbps levels. They provide cleaning robots with more complex and accurate environmental data; for example, 3D time-of-flight sensors acquire 3D structural information of the surrounding environment, and tri-color cameras identify different objects and areas in the home environment, helping the cleaning robot complete cleaning tasks more efficiently and intelligently.

[0045] When the cleaning robot is in operation, the control board receives signals transmitted from the sensors, performs internal data analysis and processing, and then issues corresponding instructions to drive the cleaning robot to perform a series of operations such as moving forward, turning, obstacle avoidance, and cleaning.

[0046] However, in related technologies, the control board and low-speed sensors, high-speed sensors, and actuators generally use standardized electronic wires, such as UL3302 electronic wires. UL3302 electronic wires are certified by UL (Underwriters Laboratories), and the connection method is one electronic wire per sensor. This connection method leads to the following problems. First, since the robot has a large number of sensors, the one-to-one connection between sensors and electronic wires inevitably requires a large number of wires. This large number of wires makes the wiring extremely complex, crisscrossing within the robot's limited internal space, significantly occupying internal space and hindering the miniaturization design of cleaning robots. Second, the dense arrangement of numerous cables easily causes cross-interference, affecting not only the stability of signal transmission but also greatly increasing the difficulty of robot maintenance.

[0047] In response, this application provides a control component, a cleaning robot, and a cleaning device, which can improve the structural compactness of the cleaning robot, meet the miniaturization requirements of the cleaning robot, and improve the maintenance efficiency of the robot.

[0048] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the cleaning robot 100 provided in this embodiment; Figure 2 This is a schematic block diagram of the structure of the control component 10 provided in this embodiment.

[0049] The cleaning equipment in this embodiment includes a cleaning robot 100 and a cleaning base station. The cleaning robot 100 is the main body that performs the cleaning task, and can be of various types, such as a sweeping robot, a mopping robot, or a window-wiping robot. In this embodiment, a sweeping robot is used as an example for explanation.

[0050] The cleaning base station establishes a communication connection with the cleaning robot 100 to maintain the cleaning robot 100, such as charging, watering, and cleaning it, so that the cleaning robot 100 can receive timely support during operation, thereby achieving efficient and stable cleaning operations.

[0051] Taking the charging of the cleaning robot 100 by the cleaning base station as an example, the cleaning base station and the cleaning robot 100 establish a communication connection through wireless communication technology (such as Bluetooth, Wi-Fi, etc.). The cleaning base station connects to the charging port of the cleaning robot 100 through a charging interface to provide power to the robot. The charging interface can use metal contacts or electromagnetic induction for charging. The cleaning base station is equipped with a charging circuit and a battery management system, which can intelligently charge according to the robot's battery status, protecting the battery's safety and lifespan.

[0052] When the robot vacuum cleaner's battery is low, it will send a charging request to the cleaning base station via its communication module. Upon receiving the request, the cleaning base station will send a guidance signal to guide the robot back to the base station for charging. After returning to the base station, the charging interface will automatically connect, and charging will begin.

[0053] The cleaning robot 100 in this embodiment includes a housing 20, a control component 10, and an execution component.

[0054] The outer shell 20 is the external protective structure of the cleaning robot 100, providing physical protection for the internal components. The outer shell 20 can be made of high-strength, lightweight engineering plastics, such as an alloy of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS), to improve the robot's impact resistance, thereby protecting the internal components from damage. Simultaneously, its lighter weight helps reduce the robot's overall weight and energy consumption.

[0055] The control component 10 is the core component of the cleaning robot 100, including the control board 1, low-speed sensor 2, high-speed sensor 4, drive component 7, first cable 3, second cable 5, and third cable 8.

[0056] The low-speed sensor 2 is connected to the control board 1 via the first cable 3, the high-speed sensor 4 is connected to the control board 1 via the second cable 5, and the driver 7 is connected to the control board 1 via the third cable 8.

[0057] The signal bandwidth of either the first cable 3 or the second cable 5 is greater than the signal bandwidth of the third cable 8, the signal bandwidth of the second cable 5 is greater than the signal bandwidth of the first cable 3, and the current capacity of the third cable 8 is greater than the current capacity of either the first cable 3 or the second cable 5.

[0058] Among them, the control board 1 is the core of the entire control component 10. It is mainly used to receive, process and analyze signals from various low-speed sensor devices 2, and issue corresponding instructions according to the preset program and algorithm to control the robot to perform various operations.

[0059] The control board 1 is typically a circuit board containing electronic components such as a microprocessor, memory chip, and input / output interfaces. During the operation of the robotic vacuum cleaner, the control board 1 determines information such as the robot's position, surrounding environment, and cleaning status based on received signals. For example, when it receives a signal from the distance sensor and detects an obstacle ahead, the control board 1 quickly analyzes the signal and issues a turning command, allowing the robot to avoid the obstacle and continue cleaning.

[0060] The low-speed sensor 2 in this embodiment can be any type of low-speed sensor.

[0061] In some embodiments, the low-speed sensor 2 includes at least one of a collision sensor, a distance sensor, and a motion state detection sensor.

[0062] In a robotic vacuum cleaner, collision sensors can be pressure-type or photoelectric collision sensors. Distance sensors can be ultrasonic or infrared sensors. Motion state detection sensors can be slip detection sensors; for example, by detecting and comparing the rotational speeds of the robot's drive and driven wheels, if the driven wheel's rotational speed is significantly lower than the drive wheel's and exceeds the normal error range, it can be determined that slippage has occurred.

[0063] In this embodiment, the first cable 3 connects the control board 1 and the low-speed sensor 2. The first cable 3 includes at least two low-speed data transmission lines 31, and the low-speed sensor 2 is provided with at least two.

[0064] At least two low-speed sensor devices 2 are electrically connected to the control board 1 via different low-speed data transmission lines 31 of the same first cable 3. For example, a collision sensor and a distance sensor can be connected to the control board 1 respectively via different low-speed data transmission lines 31 of the same first cable 3. This connection method has the following advantages compared to the prior art method where one electronic wire is used to connect only one low-speed sensor device 2:

[0065] First, since multiple low-speed sensor components 2 can be connected via the same first cable 3, the number of cables used is greatly reduced. This not only lowers costs but also prevents the internal space of the cleaning robot 100 from being occupied by a large number of cables, making the internal layout of the robot more compact.

[0066] Secondly, the reduction in the number of cables allows for more efficient use of the robot's internal space, improving the robot's structural compactness and facilitating miniaturization design.

[0067] Finally, one end of the first cable 3 is connected to the control board 1, and the other end is connected to at least two low-speed sensor components 2. The wiring is simpler, which greatly reduces the assembly difficulty of the robot and improves production efficiency.

[0068] In some embodiments, the high-speed sensor 4 includes at least one of a three-dimensional time-of-flight sensor, a three-color camera, and a lidar.

[0069] A three-dimensional time-of-flight sensor calculates the distance between the object and the sensor by emitting light pulses and measuring the time it takes for the light pulses to travel from emission to reflection back from the object, thereby obtaining three-dimensional information about the surrounding environment.

[0070] A three-primary-color camera can capture clear color images and capture color information in the environment, helping robots to better identify objects and environmental features.

[0071] LiDAR (Light Detection and Ranging) constructs a two-dimensional or three-dimensional map of the surrounding environment by emitting a laser beam and measuring the time and angle at which the laser beam is reflected back. This provides detailed information about the robot's surroundings in real time, greatly improving the robot's positioning and navigation capabilities and enabling the robot to complete cleaning tasks more efficiently.

[0072] The high-speed sensor 4 is connected to the control board 1 via a second cable 5. In one embodiment, the second cable 5 includes at least one high-speed data transmission line 51, through which the high-speed sensor 4 is electrically connected to the control board 1.

[0073] In one embodiment, such as Figure 2 As shown, at least two high-speed sensor devices 4 are provided, and one high-speed sensor device 4 is electrically connected to the control board 1 via a second cable 5. In another embodiment, as... Figure 3 As shown, the two high-speed sensor devices 4 are electrically connected to the control board 1 via different high-speed data transmission lines 51 of the same second cable 5. This design is similar to the connection method of the first cable 3, further reducing the number of cables, improving the compactness of the robot's internal structure and the regularity of the wiring, while also reducing production costs and assembly difficulty.

[0074] In some embodiments, the second cable 5 is a flexible circuit board. The flexible circuit board is formed by etching or other processes to create conductive lines on a flexible insulating substrate. Flexible circuit boards possess excellent electrical properties, meeting the requirements of high-speed signal transmission for signal integrity and low latency. Furthermore, their flexibility allows them to be flexibly bent and folded within the robot, adapting to different installation spaces and layout requirements, further reducing the robot's size and weight.

[0075] The control component 10 also includes a power supply 6, which provides electrical power to the various components of the robot. The drive component 7 is a key component for performing specific actions. For example, the drive component 7 includes a motor and an air pump. The motor drives the rollers to rotate, thus moving the robot, and the air pump generates suction for cleaning operations such as vacuuming. The power supply 6 and the drive component 7 are connected to the control board 1 via a third cable 8, thereby forming a complete electrical control system.

[0076] In this embodiment, since the power supply 6 and driving device 7 consume a large amount of power, they will generate a large current during operation. If ordinary cables are used, the insufficient load-bearing capacity may lead to safety issues such as overheating and short circuits. However, this embodiment uses a third cable 8 for connection. The third cable 8 can be a UL3302 electronic wire. The third cable 8 has a higher current carrying capacity and better insulation performance, which can withstand a larger power load, ensure stable power transmission, and greatly improve the safety of the system.

[0077] In the control component 10 of this embodiment, the low-speed sensor 2, the high-speed sensor 4, and the driver 7 are connected to the control board 1 via a first cable 3, a second cable 5, and a third cable 8, respectively. The signal bandwidth of either the first cable 3 or the second cable 5 is greater than that of the third cable 8, the signal bandwidth of the second cable 5 is greater than that of the first cable 3, and the current capacity of the third cable 8 is greater than that of either the first cable 3 or the second cable 5. This embodiment uses different cables to accommodate the signal characteristics and power requirements of different devices, resulting in neat and orderly wiring. During maintenance, repair personnel can quickly and accurately locate the corresponding device based on the cable type, greatly shortening troubleshooting time and improving maintenance efficiency.

[0078] In some embodiments, the first cable 3 further includes at least two sets of power lines to ensure that each low-speed sensor 2 receives a stable power supply.

[0079] In this embodiment, a set of power lines includes one positive power line and one negative power line, and the set of power lines corresponds to at least one low-speed data transmission line 31. For example, the control board 1 connects to a low-speed sensor 2 via a set of power lines and a data line. Taking a collision sensor as an example, the control board 1 provides the necessary power to the collision sensor through the set of power lines to ensure the normal operation of its internal circuit components. Simultaneously, the detected collision signal is transmitted back to the control board 1 via the low-speed data transmission line 31.

[0080] In this embodiment, the execution component is electrically connected to the control board 1 and performs operations such as forward movement, turning, obstacle avoidance, and cleaning under the instructions of the control component 10.

[0081] In some embodiments, the execution components include a cleaning module and a walking module.

[0082] The cleaning module is the core component of a robotic vacuum cleaner to achieve its cleaning function, and it can include a roller brush assembly, a side brush assembly, and a vacuuming assembly.

[0083] When the robot vacuum is working, the control board 1 issues commands according to the cleaning task requirements, controlling the roller brush assembly, side brush assembly, and vacuum assembly to work together. For example, when the robot starts cleaning, the control board 1 will issue a command to start the motor, driving the roller brush and side brush to rotate, and at the same time start the fan to generate suction. The roller brush picks up dust and debris on the floor, while the side brush sweeps dust and debris from the walls and corners into the range that the roller brush can reach. Then, the vacuum assembly sucks the dust and debris into the dust collection box.

[0084] The walking module is used to drive the robot to move on the ground and may include a roller assembly and a drive motor.

[0085] When the robotic vacuum cleaner is working, the control board 1 issues commands based on the received signals and the preset cleaning path to control the speed and direction of the drive motor, thereby enabling the robot to move forward, backward, and turn. For example, when the control board 1 receives a signal from the distance sensor and detects an obstacle ahead, it will issue a command to adjust the speed and direction of the drive motor so that the robot can avoid the obstacle.

[0086] In some embodiments, please refer to Figure 2 and Figure 5 To connect multiple low-speed sensor devices 2 and control board 1, the first cable 3 in this embodiment adopts a "one master, multiple slave" topology. Specifically, in each first cable 3, segments of multiple low-speed data transmission lines 31 are integrated together to form a main connection section 301, which is connected to the control board 1. The main connection section 301 is formed by integrating multiple independent low-speed data transmission lines 31 in a specific area using ribbon cable technology, and wrapping the outer layer with insulating material to form a unified connection part.

[0087] The remaining segments of the multiple low-speed data transmission lines 31 are arranged in a forked manner and are connected to multiple low-speed sensor devices 2 one by one. The end of the main connection section 301 away from the control board 1 extends into multiple independent branch segments, each branch segment connecting to a low-speed sensor device 2.

[0088] In this embodiment, the first cable 3 adopts a "one master, multiple slaves" topology, which significantly reduces the number of cables and the space occupied. The originally haphazardly distributed cables are integrated through the main connecting section 301 and the branching segments, making the internal wiring of the robot more orderly and efficient, saving space and contributing to the miniaturization of the robot. Furthermore, during assembly, workers only need to connect the main connecting section to the control board and then connect each branch segment to the corresponding low-speed sensor 2, reducing the probability of assembly errors and improving production efficiency.

[0089] In some embodiments, the first cable 3 is a flexible flat cable. The flexible flat cable of this embodiment can be laminated from multiple layers of flexible insulating material and conductive lines, allowing it to be bent freely with a small bending radius, thus adapting to the complex and compact spatial layout inside the robot vacuum cleaner. For example, the flexible flat cable can be flexibly laid out where it needs to bypass other components inside the robot. Moreover, its flat shape occupies less space than traditional round cables, further optimizing the internal spatial structure of the robot and contributing to its miniaturization design.

[0090] In some embodiments, at least one first connector 11 is provided on the control board 1. The first connector 11 includes a plastic housing and metal pins. The plastic housing is used to protect and fix the metal pins, and the metal pins are used to transmit electrical signals. Exemplarily, one end of the first cable 3 has an interface that matches the first connector 11. By inserting this interface into the metal pins of the first connector 11, an electrical connection is achieved between the first cable 3 and the control board 1. This plugging method is not only convenient and quick to install, facilitating assembly on the production line, but also ensures the stability and reliability of the connection.

[0091] Meanwhile, since a first cable 3 can connect at least two low-speed sensor devices 2 at the same time, that is, a first connector 11 can meet the connection requirements of at least two low-speed sensor devices 2. Compared with the existing technology of connecting one low-speed sensor device 2 with one connector, the number of connectors used is greatly reduced, saving costs.

[0092] Please see Figure 3 , Figure 3 Another schematic block diagram of the control component 10 provided in the embodiments of this application.

[0093] In some embodiments, the control board 1 is provided with at least one second connector 12. The second connector 12 also includes a plastic housing and metal pins. Exemplarily, one end of the second cable 5 has an interface that matches the second connector 12, and an electrical connection with the control board 1 is achieved by plugging it in.

[0094] In some embodiments, the first connector 11 includes multiple first interfaces (such as pin interfaces) that can support direct insertion of multiple low-speed data transmission lines 31 (such as FFC flexible flat cables). In other embodiments, the multiple first interfaces can also be compatible with the insertion of multiple high-speed data transmission lines 51 (such as FPC flexible circuit boards), for example, by means of an adaptive impedance matching circuit (such as an adjustable resistor network) inside the first interface, to achieve compatibility with different signal frequencies.

[0095] The second connector 12 includes multiple second interfaces (such as pin interfaces) that can support the insertion of multiple high-speed data transmission lines 51. In other embodiments, the multiple second interfaces can also be used to insert multiple low-speed data transmission lines 31, for example, by adapting the electrical characteristics of the high-speed interfaces to low-speed signal standards through a protocol conversion chip (such as a level converter).

[0096] In this embodiment, the first connector 11 and the second connector 12 can be universal connectors, such as FPC / FFC connectors. Universal connectors reduce the production cost of dedicated interfaces and are compatible with multiple cable types, thereby saving production costs.

[0097] Meanwhile, standardized interfaces reduce the problem of loose connections caused by manual soldering, and the locking structure of FPC / FFC connectors (such as flip-top type and snap-on type) makes wiring faster and more stable, improving the reliability of the connection.

[0098] In some embodiments, such as Figure 4 As shown, the low-speed sensor component 2 includes various types such as a left collision sensor, a left front cliff sensor, a slip detection sensor, a left middle cliff sensor, a left rear cliff sensor, a positioning sensor, a right collision sensor, a right front cliff sensor, an ultrasonic sensor, a right rear cliff sensor, a right middle cliff sensor, an edge sensor, a water level sensor, an encoder, and a recharge alignment sensor. These sensors play different roles in the operation of the robotic vacuum cleaner.

[0099] For example, the left collision sensor detects whether a collision has occurred on the left side of the robot. When the robot encounters an obstacle on its left side during cleaning, this sensor transmits a collision signal to control board 1. Control board 1 then adjusts the robot's movement direction to avoid continuous collisions and damage. The left front cliff sensor, left middle cliff sensor, left rear cliff sensor, right front cliff sensor, right rear cliff sensor, and right middle cliff sensor detect areas with significant drops around the robot to prevent it from falling and ensure its safe operation. The slip detection sensor monitors the operating status of the robot's drive wheels. When slippage is detected, control board 1 takes appropriate measures, such as adjusting the drive wheel speed, to ensure the robot can move normally. The positioning sensor detects whether certain parts of the robot have reached their designated positions, ensuring that the robot's various operations are executed accurately. The edge sensor helps the robot identify wall edges and obstacle edges, enabling the robot to clean efficiently along walls. The water level sensor detects the water level in the tank. When the water level is too low, control board 1 will remind the user to add water or control the robot to return to the base station to replenish water. The encoder measures the rotation angle and speed of the drive wheels, providing control board 1 with data on the robot's motion for better control of its movement path. The recharge alignment sensor helps the robot accurately align with the charging port when it needs to return to the base station for charging.

[0100] To achieve data transmission between the low-speed sensor 2 and the control board 1, this embodiment employs a grouped connection method. The left collision sensor, left front cliff sensor, and slip detection sensor are electrically connected to the control board 1 via a flexible flat cable. Similarly, the left middle cliff sensor, left rear cliff sensor, and positioning sensor are electrically connected to the control board 1 via a flexible flat cable; the right collision sensor, right front cliff sensor, and ultrasonic sensor are electrically connected to the control board 1 via a flexible flat cable; and the right rear cliff sensor, right middle cliff sensor, and edge sensor are electrically connected to the control board 1 via a flexible flat cable. The water level sensor, encoder, and recharge alignment sensor are electrically connected to the control board 1 via a flexible flat cable. This grouped connection method not only improves the neatness of the wiring but also facilitates maintenance and troubleshooting.

[0101] The high-speed sensor 4 includes a three-primary-color camera and a three-dimensional time-of-flight sensor. These two high-speed sensor 4 are electrically connected to the control board 1 via flexible circuit boards.

[0102] The driving device 7 includes a drive wheel motor, a side brush motor, a roller brush motor, a drum motor, a lifting motor, a vacuum fan, an external expansion motor, an air pump, etc. In this embodiment, the driving device 7 is used to drive the robot to work. For example, the drive wheel motor drives the robot's drive wheels to rotate, enabling the robot to move on the ground; the side brush motor drives the side brushes to rotate, cleaning dust and debris from walls and corners; the roller brush motor drives the roller brush to rotate, rolling dust and debris from the ground onto the roller brush.

[0103] These drive devices 7 are electrically connected to the control board 1 via third cables 8. Since the drive devices 7 consume a large amount of power, the third cables 8 have higher current capacity and better insulation performance, enabling them to withstand larger power loads, ensuring stable power transmission, and improving system safety.

[0104] This embodiment selects different cables based on data transmission rate and power requirements. For low-speed sensor 2, since its data transmission rate is relatively low, a flexible flat cable is sufficient to meet the data transmission needs. Furthermore, flexible flat cables offer advantages such as flexibility and small footprint, making them suitable for internal robot wiring. High-speed sensor 4, with its higher data transmission rate, requires a flexible circuit board that ensures signal integrity and low latency. For actuator 7, considering its high power consumption, a third cable 8 is used for connection, ensuring safe and stable power transmission.

[0105] Meanwhile, multiple low-speed sensor components 2 are electrically connected to the circuit board via the same first cable 3. This method reduces the number of cables, improves the compactness of the robot's internal structure, and reduces production costs and assembly difficulty.

[0106] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
