[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other.

[0024] The automatic charging technology of photovoltaic panel cleaning robots has developed rapidly in recent years. Especially in solar power generation systems, cleaning robots are used to remove dust, snow, leaves and other debris on the surface of photovoltaic panels to keep the photovoltaic panels clean, thereby improving the photoelectric conversion efficiency. However, after completing the cleaning task, the cleaning robot needs to return to the charging station for charging to ensure continuous working ability.

[0025] Traditional charging methods often rely on manual intervention or use relatively simple positioning methods, and these methods have the following deficiencies: low positioning accuracy, the positioning accuracy of the robot charging system is not high, which may cause the charging interface to fail to be accurately docked, affecting the charging efficiency and even damaging the equipment; some systems require manual auxiliary positioning, reducing the autonomy and working efficiency of the robot; due to inaccurate positioning, the robot may disconnect the charging during the charging process due to slight vibration or position deviation, resulting in charging interruption and poor charging stability.

[0026] Based on this, an exemplary embodiment of the present application provides a guiding charging device for a photovoltaic cleaning robot, which includes a charging base and a charging module. A guiding surface for guiding the positioning of the cleaning robot is provided on the charging base. The charging module includes at least one guiding roller, and the guiding roller cooperates with the guiding surface to automatically position the robot body to the charging base for charging. In this way, the cleaning robot can automatically and accurately position to the charging base for charging without manual intervention, and ensure the precise docking of the charging module and the charging base through a guiding mechanism, complete the automatic charging process, and improve the charging efficiency and stability.

[0027] An exemplary embodiment of the present application provides a guiding charging device for a photovoltaic cleaning robot, as Figures 1 to 3As shown in the figure, the device includes: a charging base 30, which is provided with a guiding surface 301 for guiding the positioning of the cleaning robot; a charging module 20 provided on the cleaning robot body 10, the charging module 20 includes at least one guiding roller 201, and the guiding roller 201 cooperates with the guiding surface 301 to automatically position the robot body to the charging base 30 for charging; wherein, the guiding roller 201 rolls along the guiding surface 301 to guide the precise docking of the charging module 20 and the charging base 30 to achieve automatic charging. A cleaning roller assembly 40 is also provided on the cleaning robot body 10. In this way, the cleaning robot can automatically and precisely position itself to the charging base 30 for charging without manual intervention, and ensure the precise docking of the charging module 20 and the charging base 30 through the guiding mechanism, completing the automatic charging process and improving the charging efficiency and stability.

[0028] In one embodiment, there are multiple guiding rollers 201, preferably two, as Figure 1 shown. The two guiding rollers 201 are respectively distributed on both sides of the charging module 20. In this way, during the docking process of the charging module 20 and the charging base 30, both guiding rollers 201 can conduct guiding, ensuring that when the cleaning robot approaches the charging base 30, the guiding rollers 201 on both sides can simultaneously contact the guiding surface 301 on the charging base 30, providing a balanced guiding force, thus ensuring the precise alignment of the charging module 20 and the charging base 30 and improving the stability during the docking process.

[0029] As Figure 4 and 5 shown, the guiding surface 301 is an inclined surface, and its shape makes the charging port of the charging base 30 gradually become narrower from wide as the cleaning robot body 10 approaches, so as to guide the robot body to precisely align with the charging position. The inclined guiding surface 301 helps the cleaning robot to naturally align with the charging port when approaching the charging base 30. Even if there is a deviation in the initial position, the inclined guiding surface 301 can guide the cleaning robot to make fine adjustments until it precisely aligns with the charging position, which can reduce the impact and error that may occur during direct positioning and simplify the automatic positioning and docking process of the cleaning robot. At the same time, as the cleaning robot approaches, the process of the charging port gradually becoming narrower is equivalent to an adaptive calibration mechanism, which can ensure that the cleaning robot docks with the charging base 30 smoothly and firmly in the final stage, avoiding charging instability or failure caused by slight position deviation.

[0030] The charging dock 30 is also provided with charging contacts 302, which are in contact with the corresponding contacts on the charging module 20 to establish an electrical connection for charging. Preferably, the charging contacts 302 are telescopically arranged. When the charging module 20 of the cleaning robot is docked with the charging dock 30, the charging contacts 302 on the charging dock 30 come into contact with the corresponding contacts on the charging module 20 and retract into the charging dock 30 under the extrusion of the charging dock 30, and can provide appropriate contact pressure to ensure the stability of current transmission, thereby improving the stability and efficiency of charging.

[0031] The charging dock 30 is integrated with a positioning sensor 303. Preferably, the positioning sensor 303 is a micro switch, which is used to accurately identify the timing when the cleaning robot body 10 reaches the charging position to start the automatic charging program. The positioning sensor 303 can sense the exact moment when the cleaning robot reaches the charging position, so that the charging program can be started immediately without additional manual operation; at the same time, the instant response of the positioning sensor 303 shortens the time interval from when the cleaning robot reaches the charging position to when actual charging starts, improving the efficiency of the entire charging process.

[0032] In one embodiment, the charging dock 30 further includes a damper 304, which is used to absorb the impact force generated during the approach and docking of the cleaning robot body 10. In this way, during the process when the cleaning robot approaches and finally contacts the charging dock 30, the damper 304 can absorb and relieve the impact force caused by factors such as the speed and weight of the cleaning robot, protecting the cleaning robot and the charging dock 30 from damage, and reducing noise and vibration during the docking process.

[0033] The charging dock 30 is usually set at a certain position of the photovoltaic panel. When the cleaning robot needs to be charged, the cleaning robot moves towards the charging dock 30, aligns the charging module 20 with the charging port, and under the coordinated action of the guide roller 201 and the guide surface 301, realizes automatic positioning and automatic charging.
