[0046] With the development of artificial intelligence and Internet of Things technologies, automated lawn mowing robots have gradually emerged in the market to replace traditional lawn mowing operations that rely on manual or semi-automatic equipment. They automatically complete lawn mowing work within a set area. However, existing lawn mowing robots still need improvement in terms of structural complexity, power transmission efficiency, intelligent control, and ease of operation, and cannot meet users' needs for high efficiency, intelligence, and data-driven lawn mowing operations.

[0047] In view of this, this utility model embodiment provides a lawn mowing robot that can realize intelligent lawn mowing operations. It is equipped with a Beidou navigation component in the vehicle body. The Beidou navigation component plans the movement path according to the navigation signal and controls the movement of the drive component, thereby achieving precise autonomous navigation and completing intelligent unattended lawn mowing operations. A safety protection component is set at the front of the vehicle body. The safety protection component is electrically connected to the drive component, so that it can stop in time in the event of a collision, thereby improving the safety of the lawn mowing robot.

[0048] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0049] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a lawnmower robot, comprising:

[0050] The vehicle body 100 has a front end and a rear end;

[0051] A drive assembly 200 is provided on the vehicle body 100 and is used to drive the vehicle body 100 to move.

[0052] A blade system 300, located at the bottom of the vehicle body 100, is used for mowing grass; and

[0053] The control system includes a safety protection component 400 located at the front end of the vehicle body 100 and a Beidou navigation component 500 located at the rear end of the vehicle body 100. The Beidou navigation component 500 is used to receive navigation signals from Beidou satellites and plan a movement path according to the navigation signals. The Beidou navigation component 500 is electrically connected to the drive component 200 to control the vehicle body 100 to move along the movement path. The safety protection component 400 is electrically connected to the drive component 200 to control the vehicle body 100 to stop moving. The Beidou navigation component 500 and the safety protection component 400 cooperate to realize the automatic operation of the lawnmower robot.

[0054] In this embodiment, the vehicle body 100 is the main structure of the lawnmower robot, providing support and stability. The drive assembly 200 provides power and controls the movement of the vehicle body 100. The blade system 300 is the core component of the lawnmower robot, used for trimming the lawn. The control system coordinates and controls the robot's operation, enabling it to automatically and efficiently complete mowing. The Beidou navigation assembly 500 processes received navigation signals to generate an environmental map and plan the robot's path before mowing. This planned path is then transmitted to the drive assembly 200, which controls the vehicle body 100 to move along it. Furthermore, a safety protection assembly 400 is triggered when the robot collides with an obstacle during mowing. This triggers the drive assembly 200 according to preset control logic, stopping the robot. This ensures safe and reliable operation during mowing.

[0055] Specifically, the lawnmower robot includes a vehicle body 100, a drive assembly 200, a blade system 300, and a control system.

[0056] The vehicle body 100 can be made of metal materials such as stainless steel and iron, and has a certain load-bearing capacity to provide support. In addition, the vehicle body 100 needs to be waterproof and corrosion-resistant to adapt to the outdoor environment.

[0057] The drive assembly 200 is used to drive the vehicle body 100 to move. The drive assembly 200 can be a motor and wheels. It is connected to the vehicle body 100 for rotation through a shaft. When the user starts the motor, the motor drives the wheels to rotate, thereby moving the vehicle body 100.

[0058] The blade system 300 is used to mow the lawn while the vehicle body 100 is moving. It is understood that the blade system 300 is located at the bottom of the vehicle body 100, and during movement, it can contact the lawn to achieve automated mowing. The blade system 300 can be blades or blade rings, and is equipped with a corresponding motor. The blades or blade rings are rotatably connected to the drive shaft of the motor, and the motor drives the blades or blade rings to rotate, thus enabling simple and convenient lawn mowing.

[0059] The control component enables intelligent, unattended lawn mowing operations. This component includes a BeiDou navigation component 500 for precise positioning and path planning, and a safety protection component 400 to protect the machine and its surrounding environment during mowing. The BeiDou navigation component 500 utilizes the BeiDou satellite system for high-precision positioning, determining the real-time location of the lawnmower robot. Based on this positioning information, the BeiDou navigation component 500 automatically plans the optimal mowing path, ensuring coverage of the entire area while avoiding duplication or omissions. It also ensures that the lawnmower robot operates within a designated area and does not exceed the boundaries. The safety protection component 400 can be a sensor electrically connected to the drive component 200. When the lawnmower robot collides with an obstacle, the sensor detects the contact, triggering a shutdown procedure. This, in turn, controls the operation of the drive component 200 according to preset control logic, stopping the lawnmower robot from moving forward.

[0060] Furthermore, refer to Figure 3 , Figure 4 as well as Figure 5 In one embodiment of this utility model, the Beidou navigation component 500 includes:

[0061] The electrical control box mechanism 510 is located at the rear end of the vehicle body 100. The electrical control box mechanism 510 is electrically connected to the drive assembly 200 to control the movement of the vehicle body 100.

[0062] Beidou antenna 520: A Beidou antenna 520 is installed on each of the opposite sides of the vehicle body 100 to receive navigation signals from Beidou satellites;

[0063] The Beidou navigation controller 530 is electrically connected to two Beidou antennas 520 to plan the movement path according to the navigation signal, and the Beidou navigation controller 530 is electrically connected to the electrical control box mechanism 510 to transmit the movement path to the electrical control box mechanism 510.

[0064] In this embodiment, the BeiDou navigation component 500 may include an electrical control box 510, a BeiDou antenna 520, and a BeiDou navigation controller 530. The electrical control box 510 may include a housing and various electrical control components housed within it. It serves as the central hub of the BeiDou navigation component 500, responsible for integrating and processing instructions from the BeiDou navigation controller 530 and outputting control instructions to the drive component 200 to ensure precise navigation and positioning of the robot. The BeiDou antenna 520 can receive signals from BeiDou satellites. The BeiDou navigation controller 530 is the core component for processing the signals received by the BeiDou antenna 520, providing accurate positioning. In this embodiment, the BeiDou antenna 520 may be multi-system and multi-frequency to achieve global navigation satellite system reception capability. The electrical control box 510 may include a driver 511, a battery 512, and electrical components 513. The driver 511 controls the speed and direction of the drive component 200, the battery 512 provides a power source for the lawnmower robot, and the electrical components 513 ensure the safe and stable operation of the circuitry within the electrical control box 510. In this way, the Beidou navigation controller 530 can achieve precise positioning and path planning, ensuring the efficiency and accuracy of the lawnmower robot during operation. To improve the circuit stability of the lawnmower robot during mowing operations, a battery pressure plate 514 can be installed inside the electrical control box mechanism 510 to fix the battery 512 inside the electrical control box mechanism 510, reducing the impact of the complex mowing environment on the circuit and facilitating circuit transmission. In addition, fans 515 and filters 516 can be installed on opposite sides of the electrical control box mechanism 510 to ensure heat dissipation and dust protection for the electrical components 513.

[0065] Furthermore, refer to Figure 2 In one embodiment of this utility model, the Beidou navigation component 500 further includes an operation panel 540, which is electrically connected to the electrical control box mechanism 510 to operate and monitor the Beidou navigation component 500.

[0066] In this embodiment, the operation panel 540 allows users to adjust the status of the lawnmower robot. The operation panel 540 may include a charging port, a voltmeter, a 4G antenna, indicator lights, lighting buttons, stop, start, power on / off buttons, and an emergency stop button for easy operation and monitoring. The operation panel 540 may also include a communication antenna for transmitting data to external devices, such as computers or smartphones, for analysis and recording. This configuration enables the lawnmower robot to have real-time monitoring capabilities, continuously monitoring its operating status and providing real-time monitoring and intuitive data display of the mowing operation.

[0067] Furthermore, refer to Figure 1 , Figure 2 as well as Figure 3In one embodiment of this utility model, a sliding groove is provided on both sides of the vehicle body 100, and a positioning hole is provided at the front end of the vehicle body 100. The safety protection component 400 includes:

[0068] The bumper 410 is movably located at the front end of the vehicle body 100;

[0069] Two sliding members 420 are provided at intervals along the length of the bumper 410. One end of each sliding member 420 is slidably connected to a groove, and one end of both sliding members 420 extends toward the interior of the vehicle body 100.

[0070] Tension spring 430, one end of which is connected to the positioning hole, and the other end of which is connected to the slider 420; and

[0071] Limit switch 440 is located inside vehicle body 100. Limit switch 440 is electrically connected to drive assembly 200, and the sensing rod inside limit switch 440 is connected to one end of slider.

[0072] The slider 420 can slide along the slide groove to lower or raise the sensing rods on the left and right sides, thereby turning the limit switch 440 off or on the drive assembly 200.

[0073] In the technical solution adopted in this embodiment, the safety protection component 400 may further include a bumper 410, a slider 420, a tension spring 430, and a limit switch 440. The vehicle body 100 is provided with a groove and a positioning hole. In this embodiment, the tension spring 430 has a first end and a second end, wherein the first end can be connected to the positioning hole, and the second end can be connected to one of the sensing rods. The bumper 410 is located at the front end of the vehicle body 100. During the movement of the vehicle body 100, when the bumper 410 contacts an obstacle, the bumper 410 is forced to slide the slider 420 in the groove, causing the sensing rod at one end of the slider 420 to descend, thereby triggering the limit switch 440 to output a trigger signal to stop the drive component 200 from running or change the direction of travel of the drive component 200. At this time, the tension spring 430 is in a stretched state and has elasticity. When the bumper 410 separates from the obstacle, the sensing rod returns to its initial position and rises under the action of elasticity.

[0074] Furthermore, refer to Figure 1 , Figure 4 In one embodiment of the present invention, the drive assembly 200 includes a tracked walking mechanism 210 disposed on the vehicle body 100 and a power component 220. The power component 220 is connected to the tracked walking mechanism 210 to drive the tracked walking mechanism 210 to rotate, thereby causing the vehicle body 100 to move.

[0075] In this embodiment, the drive assembly 200 may further include a tracked walking mechanism 210 and a power component 220. The tracked walking mechanism 210 enables the lawnmower robot to move on rough terrain, providing better grip and stability than a wheeled walking mechanism, thus adapting to complex mowing environments. The power component 220 drives the tracked walking mechanism 210 to rotate. In this embodiment, the power component 220 may include an integrated motor and reducer and a drive shaft. The integrated motor and reducer provides power and converts high-speed, low-torque into low-speed, high-torque to drive the tracked walking mechanism 210. The tracked walking mechanism 210 may use rubber tracks, which can reduce the degree of ground compaction and reduce damage to the lawn and soil. The tracked walking mechanism 210 achieves flexible movement through the cooperation of support rollers, tension rollers, and drive wheels. In addition, the tension and stability of the track are ensured by setting tensioning links, tension rollers, and bushings.

[0076] Furthermore, refer to Figure 1 , Figure 5 as well as Figure 6 In one embodiment of this utility model, the tool system 300 includes:

[0077] Mounting plate 310 is movably located within vehicle body 100;

[0079] A drive unit 330 is disposed on the mounting plate 310 and is drivenly connected to the cutter head assembly 320 to drive the cutter head assembly 320 to rotate relative to the mounting plate 310.

[0080] In this embodiment, the cutting tool system 300 may further include a mounting plate 310, a cutter head assembly 320, and a drive unit 330. In this embodiment, the mounting plate 310 is used to stably connect the drive unit 330 to the vehicle body 100. The cutter head assembly 320 is securely connected to the drive shaft of the drive assembly 330. The cutter head assembly 320 is the part that directly contacts and cuts the grass, and may include one or more rotating cutter heads. The drive unit 330 may be an engine, which directly drives the cutter head to rotate via a transmission shaft, thereby cutting the grass. The engine can be connected to a generator via a belt and pulleys. The engine drives the pulleys and belts to rotate, thereby rotating the driven shaft of the generator. The generator converts mechanical energy into electrical energy, and the generated electricity is used to power the battery 512 in the electrical control box mechanism 510, achieving the effect of energy reuse.

[0081] Furthermore, refer to Figure 2 , Figure 3 as well as Figure 5In one embodiment of the present invention, the tool system 300 further includes a lifting mechanism 340, which is disposed on the vehicle body 100 and connected to the mounting plate 310 to adjust the height of the mounting plate 310.

[0082] In this embodiment, the lifting mechanism 340 allows the lawnmower robot to adjust the height of the blade according to different mowing needs, achieving uniform cutting and protecting the lawn. Additionally, it reduces the risk of damaging the blade or the vehicle body 100 when mowing on uneven ground. The lifting mechanism 340 can be a threaded rod, threadedly connected to the mounting plate 310. When the distance between the blade assembly 320 and the bottom surface is higher than a preset height, the threaded rod is rotated, causing the mounting plate 310 to move closer to the ground, thus lowering the blade assembly 320. When the distance between the blade assembly 320 and the bottom surface is lower than the preset height, the threaded rod is rotated in the opposite direction, causing the mounting plate 310 to move away from the ground, thus raising the blade assembly 320.

[0083] Furthermore, refer to Figure 2 , Figure 3 as well as Figure 5 In one embodiment of this utility model, the lifting mechanism 340 includes a push rod motor 341, a linkage rod 342 connected to the push rod motor 341, and a lifting arm 343 connected to the linkage rod 342.

A lifting arm 343 is provided at both the left and right ends of each linkage rod 342. Both lifting arms 343 are movably connected to the mounting plate 310.

[0084] In this embodiment, the lifting mechanism 340 may further include a push rod motor 341, a linkage rod 342, and a lifting arm 343. In this embodiment, when the push rod of the push rod motor 341 extends, the linkage rod 342 moves forward in a straight line, thereby pushing the lifting arm 343 to rotate counterclockwise around its center, causing the mounting plate 310 to rise. When the push rod of the push rod motor 341 retracts, the linkage rod 342 moves backward in a straight line, pulling the lifting arm 343 to rotate clockwise around its center, thereby causing the mounting plate 310 to descend. Push rod motors 341 are provided on opposite sides inside the vehicle body 100, which can distribute the load, reduce the burden on a single push rod motor 341, improve the reliability and durability of the entire lifting mechanism 340, and also improve the stability of the mounting plate 310.

[0085] Furthermore, refer to Figure 7 , Figure 8 In one embodiment of the present invention, the cutter head assembly 320 includes a cutter head rotatably connected to the drive member 330 and a swivel blade 322 connected to the cutter head, with a swivel blade 322 connected to each of the opposite sides of the cutter head.
