Description

Technical Field

[0001] This application belongs to the field of lawn mowing equipment technology, specifically relating to a lawn mowing robot, a charging station, and a lawn mowing robot operation method. Background Technology

[0002] With the explosive growth of the yard service robot industry, lawnmowers have gradually evolved from high-end consumer products to household necessities. However, in actual use, multiple pain points such as "leaky residue after mowing" and "manual cleaning and maintenance" are becoming increasingly prominent. Currently, existing lawnmowers need to return to their charging stations periodically after completing a certain area of ​​mowing. Although some charging stations are equipped with water rinsing devices, these are only used to clean the lawnmower's blades, and this solution has significant shortcomings: on the one hand, the robot only has the function of mowing grass and lacks the ability to clean up grass debris in real time, making its operation limited and unable to meet user needs; on the other hand, when facing large-area mowing operations, the robot needs to frequently interrupt its work and return to the charging station to clean the blades. This back-and-forth cleaning mode seriously reduces continuous operation efficiency, prolongs the overall operation time, and also increases equipment energy consumption and mechanical wear. Summary of the Invention

[0003] The purpose of this application is to provide a lawn mowing robot, a charging station, and a lawn mowing robot operation method to solve the problems of existing washing devices and lawn mowing robots not being organically integrated, having limited functions, and low operation efficiency.

[0004] To achieve the above objectives, the first aspect of this application provides a lawnmower robot, comprising: The robot body is equipped with a battery module and a water supply interface; The water system includes a water storage module, a water cooling module, and a cleaning module disposed within the robot body. The water storage module is connected to the water supply interface through the water cooling module. The water cooling module is arranged corresponding to the battery module and is used for heat exchange with the battery module. The cleaning module is connected to the water storage module and is arranged corresponding to the cutter head of the robot body.

[0005] As a further improvement to the above technical solution: In some embodiments, the cleaning module includes a cleaning pipeline and a cleaning pump. The cleaning pipeline is connected to the water storage module through the cleaning pump. The cleaning pipeline is arranged around the cutter disc and has rinsing nozzles arranged towards the cutter disc.

[0006] In some embodiments, the water-cooling module includes a water-cooled radiator and water-cooled piping. The water-cooled radiator is in contact with the heat-generating part of the battery module, and the water-cooled piping is sequentially connected to the water supply interface, the water-cooled radiator, and the water storage module.

[0007] In some embodiments, the water system further includes a drainage module disposed on the robot body, the drainage module being connected to the water storage module via a drainage pipe.

[0009] In some embodiments, the water storage module includes at least two functional water tanks; Wherein, at least two of the functional water tanks are interconnected, and the water cooling module, the cleaning module, and the cleaning module are connected to one of the functional water tanks; Alternatively, at least two of the functional water tanks include a first functional water tank and a second functional water tank that are independent of each other, the water cooling module and the cleaning module are connected to the first functional water tank, and the maintenance module is connected to the second functional water tank.

[0010] To achieve the above objectives, a second aspect of this application provides a charging station for charging a lawnmower robot provided according to the first aspect, the charging station comprising: A base is provided for mounting on a foundation. The base is provided with a charging position for charging the lawnmower robot. The base is provided with a first cleaning nozzle and a second cleaning nozzle connected to an external water supply system, corresponding to the charging position. The first cleaning nozzle and the second cleaning nozzle are spaced apart along the direction in which the lawnmower robot enters the charging position. The charging pile body is mounted on the base. The charging pile body is equipped with a charging connector adapted to the battery module and a water supply connector adapted to the water supply interface. The connectors are connected to the power supply system and the water supply system.

[0011] As a further improvement to the above technical solution: In some embodiments, the charging pile further includes a water return tank, which is arranged below the base or inside the charging pile body, and the charging pile body is also provided with a water return interface connected to the water return tank; The water system also includes a drainage module installed on the robot body, wherein when the lawnmower robot returns to the charging position for charging, the drainage module connects to the return water interface.

[0012] To achieve the above objectives, a third aspect of this application provides a lawn mowing robot operation method, which utilizes the lawn mowing robot described in the first aspect and the charging station described in the second aspect; the lawn mowing robot operation method includes: Switching to the return-to-pile cleaning mode: The mowing robot performs a return-to-pile action. When the mowing robot reaches the first cleaning nozzle, the first cleaning nozzle is activated to rinse the body of the mowing robot. When the mowing robot and the plug on the charging pile body are fully connected, the connection is completed, and the robot waits for power and water replenishment. The mowing robot stops moving, and the second cleaning nozzle and the cleaning module are activated to perform rinsing work together, while controlling the blade to rotate at a low speed. Switch to power replenishment mode: After the lawn mowing robot completes the alignment, it begins to replenish power and water.

The water storage module is connected to the water supply interface via the water cooling module, allowing for water replenishment through an external water supply system. Additionally, the replenished water must first pass through the water cooling module, which dissipates heat generated during charging, ensuring the battery module operates within its optimal temperature range and improving safety. Furthermore, the cleaning module performs regular cleaning of the blades during charging or mowing operations, preventing residual material from affecting efficiency. Especially during large-area mowing, regular washing by the cleaning module keeps the blades clean, reducing the number of trips to the charging station for cleaning, improving continuous operation efficiency, significantly reducing overall working time, and also lowering energy consumption and mechanical wear.

[0018] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0020] On the one hand, please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a lawn mowing robot 100, which can be used for lawn mowing operations, and is especially suitable for yard services.

[0021] The lawnmower robot 100 provided in this embodiment includes a robot body 110 and a water system 120, with the water system 120 arranged inside the robot body 110. A control system is installed inside the robot body 110, which is used to control the operation of the robot body 110 and the water system 120.

[0022] The robot body 110 is equipped with a battery module 111 and a water supply interface, which allows external water to enter the water system 120.

[0023] Specifically, the water system 120 includes a water storage module 121, a water cooling module 122, and a cleaning module 123 disposed within the robot body 110. The water storage module 121 is connected to the water supply interface through the water cooling module 122, and is used to store a certain amount of water for use by the cleaning module 123. The water cooling module 122 is arranged corresponding to the battery module 111 and is used for heat exchange with the battery module 111. The cleaning module 123 is connected to the water storage module 121 and is arranged corresponding to the cutter head 113 of the robot body 110.

[0024] Thus, the lawnmower robot 100 provided in this embodiment integrates a water system 120, consisting of a water storage module 121, a water cooling module 122, and a cleaning module 123, within the robot body 110. The water storage module 121 is connected to the water supply interface through the water cooling module 122. This allows for water replenishment through an external water supply system, while the replenished water first passes through the water cooling module 122. The water cooling module 122 dissipates the heat generated by the battery module 111 during charging, ensuring that the battery module 111 operates within its optimal temperature range and improving safety.

[0025] In addition, the cleaning module 123 can perform regular cleaning of the blade 113 during the lawnmower robot 100's return to the charging station or during lawnmower operations, to avoid residual waste on the blade 113 affecting efficiency. Especially when dealing with large-area lawnmower operations, the regular water washing by the cleaning module 123 can keep the blade 113 clean at all times, reduce the number of times it needs to be cleaned at the charging station 200, improve continuous operation efficiency, greatly reduce overall working time, and also reduce equipment energy consumption and mechanical wear.

[0026] For further details, please refer to Figure 1 , Figure 3 and Figure 4 It is understandable that the lawnmower robot 100 typically has one or two blade discs 113 mounted on its chassis 110 to accommodate multiple blades and improve mowing efficiency. The diameter of the blade discs 113 is maximized to cut a larger area, further enhancing efficiency. Furthermore, to prevent the blades from cutting personnel or colliding with hard objects like stones during operation, an additional protective device (such as a protective plate 114) is usually added outside the blade discs 113 to protect both the blades and personnel. This structure of two blade discs 113 with added protective devices increases the difficulty of debris removal and cleaning. Therefore, this application utilizes a cleaning module 123 to better clean the back of the blades and their surrounding area from all angles, avoiding cleaning dead zones.

[0027] Specifically, the cleaning module 123 includes a cleaning pipeline 1230 and a cleaning pump. The cleaning pipeline 1230 is connected to the water storage module 121 through the cleaning pump. The cleaning pipeline 1230 is arranged around the cutter head 113, and the cleaning pipeline 1230 is provided with rinsing nozzles arranged towards the cutter head 113.

[0028] In this embodiment, the rinsing nozzles surround the cutter head 113 and are mainly responsible for cleaning the grass clippings adhering to the chassis and the top of the protective plate 114. The pipes on the protective plate 114 are evenly distributed on the mounting surface of the protective plate 114 and its two sides, and are mainly responsible for cleaning the grass clippings below the protective plate 114 and above the cutter head 113, so as to achieve all-round cleaning of the lawnmower without dead angles.

[0029] Please see Figure 1 and Figure 2 The aforementioned water-cooled module 122 includes a water-cooled radiator and a water-cooled pipe 1220. The water-cooled radiator contacts the heat-generating parts of the battery module 111. The water-cooled pipe 1220 sequentially connects to the water supply interface, the water-cooled radiator, and the water storage module 121. Thus, after connecting to an external water supply system, the cold water supplied by the system passes through the water-cooled pipe 1220 and enters the water-cooled radiator. The water-cooled radiator exchanges heat with the battery module 111, and the water flowing through the radiator carries away heat, thereby cooling the entire battery module 111 (ensuring the battery temperature in the battery module 111 remains stably below 60°C). This ensures that the battery module 111 maintains a suitable operating temperature during charging, improving reliability and safety.

[0030] Furthermore, the arrangement of the water-cooling module 122 improves the heat dissipation efficiency of the battery module 111, allowing for the selection of a larger capacity battery module 111 and a higher charging power. For example, compared to the charging power of traditional charging piles below 100W and charging time of over 120 minutes, this invention can control the overall temperature of the charging module within a safe range under a high-power charging of 180W, greatly shortening the charging time (in actual testing, the charging time can be controlled within 50 minutes with the same capacity battery module 111), thus improving the overall lawn mowing efficiency.

[0031] Optionally, the water-cooled radiator can be formed by connecting multiple branch pipes to the water-cooling pipe 1220, or it can be a heat sink with a water flow channel.

[0032] It should be noted that although this embodiment only describes the water-cooling module 122, the robot body 110 may also be equipped with an air-cooling system or other heat dissipation methods. Therefore, this embodiment is only for illustrative purposes and is not intended to limit the scope of protection of this application.

[0033] The water-cooling module 122 also includes a temperature sensor; a temperature sensor is installed on the water-cooling pipe 1220 and / or the water storage module 121. In this embodiment, temperature sensors can be installed on both the water-cooling pipe 1220 and the water storage module 121 to monitor the water temperature in real time, ensuring that the water temperature meets the cooling requirements. When the water temperature in the water storage module 121 is too high, the high-temperature water can be discharged. The discharged high-temperature water can be stored in an underground pre-buried water tank and reused after cooling or used as backup water for cleaning.

[0034] Please see Figure 1 , Figure 3 and Figure 4Furthermore, the water system 120 also includes a drainage module 124 mounted on the robot body 110, which is connected to the water storage module 121 via a drainage pipe. The drainage module 124 can be used to quickly drain and recycle water from the water storage module 121, enabling cold water circulation for the water-cooled module 122 during the charging process of the battery module 111. It can also be used for water replacement in the water storage module 121, or to drain water when not in use for extended periods to prevent algae growth, or for discharging wastewater from cleaning the water storage module 121.

[0035] Optionally, the drainage module 124 includes a drainage pipe connected to the water storage module 121, and an electrically controlled drainage valve may be installed on the drainage pipe.

[0036] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, the water system 120 further includes a maintenance module 125, which is connected to the water storage module 121 and has maintenance nozzles mounted on the chassis of the robot body 110. The maintenance module 125 can spray water from the water storage module 121 evenly onto the lawn through the maintenance nozzles for watering and maintenance.

[0037] Furthermore, the maintenance module 125 also includes a maintenance pump and a maintenance pipeline 1250. One end of the maintenance pipeline 1250 is connected to the water storage module 121 via the maintenance pump, and the other end is connected to the maintenance nozzle.

[0038] Thus, this solution allows the use of a lawnmower robot 100 to replace manual watering or the use of pre-embedded automatic sprinkler pipes for maintenance. This avoids the maintenance costs associated with manual watering and the damage to the lawn caused by the installation of automatic sprinkler pipes, significantly saving costs and achieving multiple uses with a single machine. Furthermore, it prevents damage to the lawnmower robot 100 from the protruding nozzles of the pre-embedded automatic sprinkler pipes, while also reducing interference with pedestrian traffic and improving the flatness and aesthetics of the lawn.

[0039] Please see Figure 1 and Figure 2 In some embodiments, the water storage module 121 includes at least two functional water tanks 1210 to increase water storage capacity and extend operation time. The at least two functional water tanks 1210 are interconnected, and the water cooling module 122, the cleaning module 123, and the cleaning module 123 are connected to one of the functional water tanks 1210.

[0040] In other embodiments, at least two functional water tanks 1210 include a first functional water tank 1210 and a second functional water tank 1210 that are independent of each other. The water cooling module 122 and the cleaning module 123 are connected to the first functional water tank 1210, and the maintenance module 125 is connected to the second functional water tank 1210. In this way, the water used by the water cooling module 122 and the cleaning module 123 can be physically isolated from the water used by the maintenance module 125. This allows soluble nutrients to be added to the second functional water tank 1210, or clean water can be used directly.

[0041] Please see Figure 5 and Figure 6 On the other hand, this embodiment also provides a charging station 200 for charging the lawnmower robot 100 provided in the above embodiment. The lawnmower robot 100 can automatically return to the charging station to recharge when it finishes its current task or runs out of power.

[0042] In this embodiment, the charging pile 200 includes a base 210 and a charging pile body 220 disposed on the base 210. The base 210 is used to be disposed on the foundation, and the base 210 is provided with a charging position for charging the lawnmower robot 100. The base 210 is provided with a first cleaning nozzle 211 and a second cleaning nozzle 212 connected to an external water supply system corresponding to the charging position. The first cleaning nozzle 211 and the second cleaning nozzle 212 are spaced apart along the direction in which the lawnmower robot 100 enters the charging position. The charging pile body 220 is disposed on the base 210, and the charging pile body 220 is provided with a charging connector adapted to the battery module 111 and a water supply connector adapted to the water supply interface. The charging connector is connected to an external power supply system, and the water supply connector is used to connect to an external water supply system.

[0043] In this embodiment, to facilitate water and energy replenishment, the charging connector and the water supply connector of the battery module 111 are integrated into a module male connector 221. Similarly, the charging port and water supply interface of the battery module 111 on the robot body 110 are integrated into a module female connector 112, so that charging docking and water replenishment docking can be completed in one go through the plugging and mating of the male and female connectors.

[0044] Understandably, the external power supply system can come from the external power grid or be powered by photovoltaics.

[0045] Please refer to the following: Figure 7 In this embodiment, the charging pile 200 also includes a water return tank 230, which is located below the base 210 or integrated into the charging pile body 220. The charging pile body 220 is also provided with a water return interface connected to the water return tank 230. The water return tank 230 can be directly connected to an external water supply system (such as a tap water system) for automatic water replenishment.

[0046] In some embodiments, the water return tank 230 can be pre-buried underground or placed on the ground. When the lawnmower robot 100 returns to its charging position for charging, the drainage module 124 connects to the water return interface. The water return tank 230 can be used to collect water discharged from the drainage module 124. Furthermore, pre-burying it underground prevents the water from being heated by external temperatures and facilitates water cooling. Alternatively, it can be integrated into the charging pile body 220.

[0047] Furthermore, the return water tank 230 can also pump the water in the tank directly to the water supply connector on the charging pile body 220 through the water supply pump 231, so that it can re-enter the water cooling module 122 and the water storage module 121 to achieve circulating cooling.

[0048] Furthermore, a level gauge is installed in the return water tank 230. When the water level reaches a preset height, the water stored in the return water tank 230 is used first to avoid water waste. When the water level in the return water tank 230 is too low, the external water supply system is activated in a timely manner to replenish the water.

[0049] On the other hand, please refer to Figures 1 to 7 This embodiment also provides a lawn mowing robot operation method, which uses the lawn mowing robot 100 and the charging pile 200 provided in the above embodiment.

[0050] The lawnmower robot 100 has four operating modes: a stubble cleaning mode, a power replenishment mode, a mowing mode, and a maintenance mode. The robot's operation method involves switching between these modes.

[0051] Switch to the return-to-pile cleaning mode: The mowing robot 100 performs the return-to-pile action. When the mowing robot 100 reaches the first cleaning nozzle 211, the first cleaning nozzle 211 is activated to rinse the body of the mowing robot 100. When the mowing robot 100 and the plug on the charging pile body 220 are connected, the connection is completed and the robot waits for power and water replenishment. The mowing robot 100 stops moving and the second cleaning nozzle 212 and the cleaning module 123 are activated to perform rinsing work together, and the blade disc 113 is controlled to rotate at a low speed.

[0052] Specifically, when returning to the charging station 200 for cleaning or recharging, the RTK antenna located near the charging station 200 transmits the real-time position of the lawnmower robot 100 to the control center within the charging station 200. When the lawnmower robot 100 approaches the charging station 200 at a certain distance, the infrared device located at the rear of the charging station 200 activates to assist the lawnmower robot 100 in aligning with the station. Once the lawnmower robot 100 is properly positioned, it begins its return-to-station movement. The control center sends a command to the lawnmower to slowly reverse, while the infrared device at the rear of the charging station 200 continuously monitors the distance between the lawnmower robot 100 and the charging port.

[0053] Furthermore, when the tail of the lawnmower 100 reaches the first cleaning nozzle 211, the first cleaning nozzle 211 begins to work, spraying a water curtain to wash the body of the lawnmower 100. The lawnmower 100 continues to move backward, and when it contacts the connector on the charging station 200, the lawnmower 100 stops reversing and lowers the blade 113 to its lowest point. The control center then starts to control the cleaning nozzles on the lawnmower body to work and activates the second cleaning nozzle 212 on the charging station 200. At the same time, the blade 113 also rotates at a low speed, so that the rinsing nozzles located on the chassis and the first and second cleaning nozzles 211 and 212 on the charging station 200 work together to clean hard-to-reach areas, greatly improving the cleaning effect.

[0054] In some embodiments, the first cleaning nozzle 211 and the second cleaning nozzle 212 are arranged opposite each other, and the first cleaning nozzle 211 and the second cleaning nozzle 212 are inclined relative to the base 210, with an included angle of inclination of 20° to 55°, preferably 30°. The water flow rate sprayed by the first cleaning nozzle 211 and the second cleaning nozzle 212 is 8 to 15 m / s.

[0055] Switching to power replenishment mode: After the lawnmower robot 100 completes its alignment with the mower piles, it begins to replenish power and water. Cold water passes through the water-cooling module 122 to dissipate heat from the battery module 111 before entering the water storage module 121 to wait for backup, thus simultaneously cooling the battery module 111. The specific alignment action is the same as that in the mower return and cleaning mode, and will not be described in detail here.

[0056] Switch to mowing mode: Set the mowing path and perform mowing operations along the set path. When the preset mowing operation is completed, start the cleaning module 123 to clean the cutter head 113.

[0057] Switch to maintenance mode: Replenish sufficient maintenance water to the water storage module 121 and set the maintenance path. Control the lawnmower robot 100 to walk along the set maintenance path, and simultaneously activate the maintenance module 125 to spray maintenance water along the path through maintenance nozzles. The maintenance path can be the same as the lawnmower path. When the water level in the water storage module 121 is detected to be below 5% or the battery is insufficient, the lawnmower will return to the charging station 200 for charging and water replenishment. During this time, the cleaning system will not operate.

[0058] Compared with the prior art, the technical solution provided in this embodiment has the following advantages: 1. The lawnmower robot provided in this application has a self-cleaning system, eliminating the need for regular manual cleaning and saving significant labor costs. Furthermore, the robot's built-in rinsing nozzles are located above the protective plate 114 and between the protective plate 114 and the blade disc 113, enabling it to clean areas obscured by the protective plate 114 and blade disc 113, resulting in a more thorough cleaning compared to traditional methods.

[0059] 2. The lawnmower robot and charging station 200 provided in this application have a combined charging and water-cooling function, enabling high-power fast charging. Compared with the charging power of traditional charging stations below 100W and charging time of more than 120 minutes, this application can control the overall temperature of the charging module within a safe range under high-power charging of 180W, greatly shortening the charging time and improving the overall lawnmower efficiency.

[0060] 3. The lawnmower robot provided in this application is equipped with a functional water tank 1210, which, in addition to being used for charging, heat dissipation, and self-cleaning of the lawnmower robot itself, can also be used for lawn maintenance, such as watering, when the lawnmower is not mowing the lawn. This avoids the need to place automatic sprinklers on the lawn, prevents collisions and injuries to people running on the lawn or damage to the lawn, and improves the utilization rate of the lawnmower robot 100.
