Description
Technical Field
[0001] This utility model relates to the field of intelligent lawnmower technology, specifically an intelligent lawnmower with track cleaning capability. Background Technology
[0002] With the development of automation and intelligent technologies, intelligent lawnmowers are becoming increasingly popular because they can autonomously complete lawn mowing tasks. In order to adapt to complex terrain (such as slopes and uneven grasslands), some intelligent lawnmowers have adopted tracked walking mechanisms, which have stronger grip and better passability compared to wheeled structures.
[0003] However, when tracks operate in wet, muddy, or grassy environments, foreign objects such as mud, grass clippings, and stones can easily adhere to and become stuck between the track plates, drive wheels, and guide wheels. These deposits increase the running resistance of the tracks, leading to increased load on the drive motor and higher energy consumption. In severe cases, they can even cause motor overload and stalling, damaging the transmission system. In addition, excessive deposits can reduce the track's grip, causing slippage and affecting the machine's walking stability and positioning accuracy. They may even cause the machine to get stuck in the mud and be unable to get out. Therefore, a smart lawnmower with track cleaning capability is needed to solve the existing shortcomings. Utility Model Content
[0004] The present invention aims to provide a tracked intelligent lawnmower to solve the above-mentioned technical problems.
[0005] In view of this, the present invention provides a tracked intelligent lawnmower, comprising:
[0006] Organism;
[0007] A walking system is provided on the machine body, and the walking system includes at least one pair of triangular track structures for driving the machine body to move;
[0008] A mudguard assembly is disposed above the track structure;
[0009] A track self-cleaning system, integrated into the mudguard assembly, is used to remove foreign objects adhering to the track; the track self-cleaning system includes:
[0010] Mechanical brush cleaning mechanism is used to physically scrape the surface of the track;
[0011] Airflow cleaning mechanism, used to spray high-pressure gas onto the track surface;
[0012] The intelligent control system is electrically connected to the track self-cleaning system and is used to sense the track status and control the mechanical brush cleaning mechanism and / or airflow cleaning mechanism to start working as needed.
[0013] Furthermore, the mudguard assembly is a figure-eight arch structure adapted to the triangular track structure.
[0014] Furthermore, the mudguard assembly includes:
[0015] The front baffle is located on one side of the machine body in the direction of travel and is roughly parallel to the front side of the track structure.
[0016] The rear baffle is approximately parallel to the rear side of the track structure.
[0017] Furthermore, the mechanical brush cleaning mechanism is disposed on the rear baffle and includes:
[0018] At least one drive shaft is rotatably mounted on the rear baffle;
[0019] At least one set of cleaning brushes is fixed to the drive shaft.
[0020] Furthermore, when the cleaning brush is not in operation, its bristles maintain a gap with the track surface; when in operation, the drive shaft drives the cleaning brush to rotate, causing the bristles to contact and scrape the track surface to remove the attached substances.
[0021] Furthermore, the airflow cleaning mechanism is disposed on the front baffle and includes:
[0022] At least one nozzle is rotatably mounted on the front baffle;
[0023] The gas supply unit is located inside the machine body and is connected to the nozzle through a pipeline to provide high-pressure gas.
[0024] Furthermore, the nozzle can rotate between a working position and a retracted position; in the working position, the nozzle's outlet faces the track surface for high-pressure gas jet cleaning; in the retracted position, the nozzle retracts to the inside of the front baffle.
[0025] Furthermore, at least one protective strip is provided on the inner side of the front baffle. The position of the protective strip corresponds to the air outlet of the nozzle when it is in the retracted position. It is used to block and protect the air outlet of the nozzle when it is in the retracted position to prevent foreign objects from clogging it.
[0026] Furthermore, the intelligent control system includes:
[0027] The sensor module is used to collect data related to the track status, including the load current of the track drive motor, track speed and / or image information of the track surface;
[0028] The main control unit, connected to the sensor module, is used to receive and analyze the data, determine whether the track needs to be cleaned according to a preset algorithm, and generate control commands when cleaning is required.
[0029] The drive module is connected to the main control unit, the mechanical brush cleaning mechanism and the airflow cleaning mechanism respectively, and is used to receive and execute the control commands to control the start and stop, working mode and action sequence of the cleaning mechanism.
[0030] Furthermore, the sensor module includes at least one of the following sensors:

[0046] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0047] like Figure 1-4 As shown, this utility model provides a technical solution: an intelligent lawnmower capable of track cleaning, including...
[0048] The main body 1 is made of high-strength, lightweight engineering plastics or glass fiber reinforced materials, and has internal compartments to house core components such as the main control board, battery pack, drive motor, and air pump. Drainage holes are designed at the bottom of the main body 1 for easy cleaning and drainage of accumulated water.
[0049] The walking system is set on the body 1. The walking system includes at least one pair of triangular track 2 structures for driving the body 1 to move. The track 2 is made of wear-resistant and non-slip rubber or polyurethane composite material. The surface of the track 2 is designed with non-slip texture and self-cleaning grooves to reduce the adhesion of foreign objects.
[0050] The mudguard assembly, which is installed above the track 2 structure, mainly serves to block mud, grass clippings and water kicked up by the track 2, and protect the internal components of the machine body 1. At the same time, it serves as the mounting platform for the cleaning mechanism, tightly integrating the cleaning system with the track 2.
[0051] Track 2 self-cleaning system, integrated into the mudguard assembly, is used to remove foreign objects adhering to track 2; the track 2 self-cleaning system includes:
[0052] Mechanical brush cleaning mechanism, used to physically scrape the surface of track 2;
[0053] An airflow cleaning mechanism is used to spray high-pressure gas onto the surface of track 2.
[0054] The intelligent control system, electrically connected to the self-cleaning system of track 2, is used to sense the status of track 2 and control the mechanical brush cleaning mechanism and / or airflow cleaning mechanism to start working as needed. The mudguard assembly is an eight-shaped arch structure adapted to the triangular track 2 structure, which includes:
[0055] The front baffle 3 is located on one side of the machine body 1 in the forward direction and is roughly parallel to the front side of the track 2 structure.
[0056] The rear baffle 4 is roughly parallel to the rear side of the track 2 structure.
[0057] like Figure 1 and Figure 3 As shown, the mechanical brush cleaning mechanism is mounted on the rear baffle 4 and includes:
[0058] At least one drive shaft 5 is rotatably mounted on the rear baffle 4, and a small DC motor or stepper motor is mounted on the outside of the rear baffle 4 and connected to one end of the drive shaft 5 via a coupling or gear set. In this application, four drive shafts 5 are provided.
[0059] At least one set of cleaning brushes 6 is fixed on the drive shaft 5. In this application, one set includes two cleaning brushes 6. The cleaning brushes 6 are made of hard nylon brushes or steel wire brushes and are fixed on the drive shaft 5 by buckles or bolts. The length and hardness of the brush bristles are designed to make slight contact with and effectively scrape off the attachments on the surface of the track 2, but without excessively abrading the track 2.
[0060] In the non-working state, the bristles of the cleaning brush 6 maintain a gap with the surface of the track 2; in the working state, the drive shaft 5 drives the cleaning brush 6 to rotate, so that the bristles contact and scrape the surface of the track 2 to remove the attached substances.
[0061] Specific workflow: Under the command of the intelligent control system, the drive motor starts, driving the drive shaft 5 and the cleaning brush 6 to rotate, so that the brush bristles are perpendicular to the surface of the track 2 and pressed together. At the same time, the drive shaft 5 can maintain low-speed rotation or reciprocating swing to powerfully scrape the surface of the track 2.
[0062] like Figure 1 , Figure 2 and Figure 3 As shown, the airflow cleaning mechanism is mounted on the front baffle 3 and includes:
[0063] At least one nozzle 7 is rotatably mounted on the front baffle 3. In this application, four nozzles 7 are installed, and four protective baffles 8 are installed accordingly. The nozzles 7 are controlled by a micro rotary servo motor or stepper motor, which can achieve rotation from 0 to 180 degrees. The nozzles 7 are designed with flow channels inside. A high-speed solenoid valve is set between the air source and the nozzles 7 and is controlled by an intelligent control system to precisely control the flow of air.
[0064] The gas supply unit is located inside the body 1 and is connected to the nozzle 7 via a pipeline to provide high-pressure gas;
[0065] The nozzle 7 can rotate between a working position and a retracted position. In the working position, the air outlet of the nozzle 7 faces the surface of the track 2 and performs high-pressure gas jet cleaning. In the retracted position, the nozzle 7 retracts to the inside of the front baffle 3. At least one protective strip 8 is also provided on the inside of the front baffle 3. The position of the protective strip 8 corresponds to the air outlet of the nozzle 7 when it is in the retracted position. It is used to block and protect the air outlet of the nozzle 7 when it is in the retracted position to prevent foreign objects from clogging it.
[0066] Standby state: The nozzle 7 is retracted to the inside of the front baffle 3. At this time, the air outlet of the nozzle 7 is blocked by the protective baffle 8 to prevent dust and rainwater from entering.
[0067] Operating status: Under the command of the intelligent control system, the rotary servo first drives the nozzle 7 to rotate out and adjust to the optimal spray angle (for example, aiming at the meshing point of the drive wheel and track 2 or the surface of track 2). Then, the solenoid valve opens, and high-pressure gas (about 0.5-0.8MPa) is sprayed out from the nozzle 7 at high speed to blow away and remove stubborn dirt from the gaps and surface of track 2.
[0068] like Figure 1 and Figure 4 As shown, the intelligent control system includes:
[0069] Sensor module 9 is used to collect data related to the state of track 2, including the load current of the drive motor of track 2, the speed of track 2 and / or image information of the surface of track 2;
[0070] For example, infrared sensors: Inside the mudguard assembly, facing the surface of track 2, one (or several) pairs of infrared beam-through or reflective sensors are installed. The cleanliness of the track 2 surface is determined by measuring the degree to which infrared light is blocked by mud or grass clippings.
[0071] The main control unit 10 is connected to the sensor module 9 and is used to receive and analyze data, determine whether the track 2 needs to be cleaned according to a preset algorithm, and generate control commands when cleaning is required.
[0072] The drive module 11 is connected to the main control unit 10, the mechanical brush cleaning mechanism and the airflow cleaning mechanism respectively, and is used to receive and execute control commands to control the start and stop, working mode and action sequence of the cleaning mechanism.
[0073] Sensor module 9 includes at least one of the following sensors:
[0074] The current sensor, employing a Hall effect current sensor, is connected in series in the power supply circuit of the left and right track drive motors. It is used to monitor the motor's operating current in real time.
[0075] A speed sensor is used to monitor the actual speed of track 2;
[0076] An image sensor is used to capture images of the surface of track 2 to identify foreign object attachment.
[0077] When performing mowing tasks, this intelligent lawnmower's intelligent control system continuously monitors the current, infrared signals, or surface images of the track 2 motor to determine if the track 2 is dirty or under abnormal load. Once cleaning is detected, the system automatically pauses or slows down and sequentially initiates a self-cleaning program consisting of mechanical brushes and high-pressure airflow to remove attached foreign objects. After cleaning is completed, mowing operations resume. In addition, the system supports multiple operating modes:
[0078] Scheduled cleaning mode: Automatically starts a preventative cleaning cycle according to a preset period (e.g., every 30 minutes of work).
[0079] Manual forced mode: Users can trigger the cleaning process instantly via mobile app or physical button on the device.
[0080] Deep Cleaning Mode: When the machine finishes its task and returns to the charging station, it automatically performs a full and thorough cleaning to ensure that the track 2 remains clean while in standby mode.
[0081] Through the aforementioned intelligent collaborative operation, this invention ensures that the track 2 remains clean under various working conditions, thereby maintaining optimal working condition and significantly improving the practicality, reliability, and user experience of the intelligent lawnmower.
[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
