Description

Technical Field

[0080] Please also refer to Figures 1 to 8 This utility model provides an embodiment of a workstation for a cleaning robot.

[0081] In some embodiments, such as Figures 1 to 3 as well as Figures 6 to 8 As shown, this utility model provides a workstation for a cleaning robot, comprising: a housing assembly 1, a water injection assembly 2, a charging mechanism 3, a positioning mechanism 4, and a hot water supply assembly 5. The water injection assembly 2 is disposed on the housing assembly 1 and is used to inject water into the cleaning robot; the charging mechanism 3 is disposed inside the housing assembly 1 and is used to charge the cleaning robot; the hot water supply assembly 5 is connected to the water injection assembly 2 and is used to provide hot water.

[0082] In this embodiment, the housing assembly 1 has a receiving cavity, and the charging mechanism 3, the water injection assembly 2, and the hot water supply assembly 5 are disposed within the receiving cavity of the housing assembly 1. The workstation provides services to the cleaning robot. After the cleaning robot is aligned with the workstation, the charging mechanism 3 can charge the cleaning robot. Simultaneously, the water injection assembly 2 opens to add clean water to the cleaning robot, allowing it to continuously perform floor cleaning. In this embodiment, the hot water supply assembly 5 is connected to the water injection assembly 2, enabling it to heat the water provided by the water injection assembly 2 before injecting it into the cleaning mechanisms of the squeegee, disc brush, or roller brush.

[0083] Thus, the workstation provided in this embodiment has a water heating function, which can heat the water used to clean the squeegee, disc brush, or roller brush of the cleaning robot before it flows out and is injected into the cleaning mechanism of the squeegee, disc brush, or roller brush. In this way, the hot water can more easily dissolve oil stains and solidified dirt, thereby improving the cleaning effect of the squeegee, disc brush, or roller brush of the cleaning robot.

[0084] In some embodiments, please refer to Figure 1 and Figure 6 The workstation also includes a positioning mechanism 4 for docking with the cleaning robot, the positioning mechanism 4 being located on the housing assembly 1. The positioning mechanism 4 includes: a first positioning structure 41 having a positioning mark; and a second positioning structure 42 having a groove on the surface of the housing assembly 1.

[0085] In this embodiment, the first positioning structure 41 and the second positioning structure 42 are positioning windows. The first positioning structure 41 is provided with a positioning marker, which can be a QR code, barcode, label, or other identifier with a specific pattern. The positioning marker can be sensed and identified by a sensor installed on the cleaning robot. For example, when the positioning marker is a label, the sensor on the cleaning robot can be a camera. In this embodiment, the first positioning structure 41 uses a positioning marker. As the cleaning robot moves towards the workstation, the camera on the cleaning robot can scan the positioning marker in real time. Based on the information from the positioning marker, the robot can determine the pose information of the workstation and reach the workstation according to the pose information to complete the alignment of the water inlet 24, charging mechanism 3, etc. The second positioning structure 42 provides coarse positioning, enabling the cleaning robot to perform the initial positioning with the workstation. The first positioning structure 41 enables high-precision positioning between the cleaning robot and the workstation. By cooperating with the first positioning structure 41 and the second positioning structure 42, the positioning accuracy between the cleaning robot and the workstation can be improved, thereby increasing the probability of successful docking. In this embodiment, the second positioning structure 42 is a groove structure. The laser radar on the front of the cleaning robot identifies the groove to determine the pose of the workstation. Then the cleaning robot turns around and moves backward toward the workstation. The camera on the back of the cleaning robot detects the positioning mark to achieve precise alignment.

The automatic charging electrode 32 includes a positive electrode and a negative electrode, is electrically connected to the charger 31, and extends out of the housing assembly 1. When the cleaning robot docks with the workstation, the receiving electrode of the cleaning robot docks with the automatic charging electrode 32, thereby charging the cleaning robot.

The first pressure reducing valve 26 can control the water pressure flowing out of the water inlet 24 to prevent excessive water pressure from damaging the internal components of the cleaning robot. The first flow meter 27 can accurately control the amount of clean water injected into the cleaning robot.

[0092] In some embodiments, such as Figure 4 As shown, the first pressure reducing valve 26 can also be installed between the clean water inlet 21 and the first three-way pipe 22.

[0094] In this embodiment, the clean water flowing into the clean water inlet 24 can flow into the hot water inlet pipe 52 via the second three-way pipe 51, and further flow to the heating device via the hot water inlet pipe 52. The heating control circuit 53 can drive the heating device to work, thereby heating the clean water so that the water used for cleaning the cleaning modules of the cleaning robot, such as the squeegee and the brush, is hot water. The second water-stop solenoid valve 54 can control the flow of water, and the second pressure reducing valve 55 can control the water pressure flowing into the heating device.

[0095] In some embodiments, such as Figure 4 As shown, the second pressure reducing valve 55 can also be disposed between the second three-way pipe 51 and the second water-stop solenoid valve 54.

[0097] In this embodiment, the controller is an MCU, and the overcurrent detection chip U20 can realize current acquisition and hardware overcurrent protection. The controller is mounted on the control board. The heating interface J5 is the connection port for connecting the heating device. The second switch Q46 can control the opening and closing of the power supply to the external drive and device. Specifically, the controller MCU can output a corresponding electrical signal to control the on / off state of the first switch Q45, thereby controlling the on / off state of the second switch Q46. When the power supply is on, the heating control circuit 53 can output a working signal to the heating device to drive the heating device to work. When the power supply is off, the heating control circuit 53 will not output a working signal to the heating device. The third switch Q47 can realize the hardware overcurrent automatic power-off function. For example, when the current is too large, the overcurrent detection chip U20 outputs a corresponding electrical signal to the controlled terminal of the third switch Q47 to control the on / off state of the third switch Q47, thereby controlling the on / off state of the second switch Q46, thereby shutting off the circuit power supply and preventing the circuit from burning out. It should be noted that the overcurrent standard can be set according to the actual situation and user needs. Power supply V can power the overcurrent detection chip U20, specifically...
