[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides a remote-controlled lawnmower with remote control functions including chassis 10 lifting, cruise control, steering, U-turn, and remote engine start / stop 18. The remote control device has a high degree of integration and practical functions, which can effectively reduce the user's workload and improve the user experience.

[0033] Please refer to this as well. Figures 1 to 6 The remote-controlled lawnmower provided by this utility model includes a walking component, a drive component, a chassis 10, a suspension assembly, an engine 18, a remote control device, a wireless signal receiver, and a controller 11; the walking component includes a front drive wheel 13 and a rear drive wheel 14; the drive component includes a travel motor 15 for driving the walking component, the travel motor 15 is fixedly installed, and the travel motor 15 is connected to the front drive wheel 13 and the rear drive wheel 14 in a transmission connection.

[0034] The chassis 10 is connected to the suspension assembly and can be raised and lowered. An electric push rod 12 is provided between the chassis 10 and the suspension assembly. The electric push rod 12 is used to drive the chassis 10 to rise and fall. The engine 18 is located on the top of the chassis 10. The remote control device is used to transmit wireless control radio frequency signals. The wireless signal receiver is installed on the chassis 10 and is used to receive the wireless control radio frequency signals transmitted by the remote control device. The controller 11 is located on the chassis 10 and is connected to the electric push rod 12, the wireless signal receiver, the drive motor 15, and the engine 18.

[0035] Specifically, each of the two front drive wheels 13 and the two rear drive wheels 14 is equipped with a corresponding drive motor 15, meaning there are four drive motors 15 in total. These four drive motors 15 drive the front drive wheels 13 and the rear drive wheels 14 to rotate. The controller 11 is connected to the drive motors 15 via a signal connection. In use, commands can be issued by operating the remote control device to enable the remote-controlled lawnmower to perform actions such as cruise control, steering, and U-turns.

[0036] When cruise control is in operation, the controller 11 controls the four drive motors 15 to work synchronously and continuously, and the remote-controlled lawnmower travels at a constant speed. When turning, the four motors work in the same direction, and the controller 11 changes the speed of the drive motors 15 on the left and right sides, thereby changing the speed on the left and right sides, and turning is achieved by relying on the speed difference between the left and right sides. When making a U-turn, the controller 11 controls the drive motors 15 on the left and right sides to rotate in opposite directions, thereby causing the remote-controlled lawnmower to travel in the opposite direction.

[0037] Furthermore, by operating the remote control device to issue a command to raise and lower the chassis 10 of the remote-controlled lawnmower, the wireless signal receiving device receives the wireless control radio frequency signal issued by the remote control device, and the controller 11 controls the electric push rod 12 to move according to the signal received by the wireless signal receiving device. The electric push rod 12 raises and lowers, thereby driving the chassis 10 to raise and lower, and adjusting the height of the chassis 10.

[0038] With this setup, in complex road conditions such as wading through water or climbing slopes, the chassis 10 can be raised or lowered remotely via a remote control device, making it easier for the remote-controlled lawnmower to traverse these complex terrains, improving its mobility, and preventing the chassis 10 from being bumped or knocked over. The remote-controlled lawnmower has a high degree of remote control capability, practical functions, and is flexible and convenient when performing lawnmowing operations, which can reduce the user's workload and improve the user experience.

[0039] In addition, the blade 101 of the remote-controlled lawnmower is mounted on the chassis 10. The chassis 10 can be raised and lowered remotely via a remote control device, allowing the blade 101 to be adjusted to suit lawns of different heights, providing flexibility and convenience while ensuring effective mowing. The engine 18 is connected to the controller 11 via a signal connection. The chassis 10 also has a cover 19 that covers the engine 18. The remote-controlled lawnmower provided in this embodiment is a plug-in hybrid electric vehicle (PHEV), meaning it can be driven by electricity or fuel. The engine 18 can be remotely started / stopped via the remote control device. Specifically, when starting, the controller 11 controls a relay to activate the engine 18; when stopping, the controller 11 controls a kill switch to activate the engine 18.

[0040] Please refer to this as well. Figures 1 to 6 The electric push rod 12 is located between the chassis 10 and the rear axle of the suspension assembly. One end of the electric push rod 12 is mounted on the rear axle of the suspension assembly, and the other end is mounted on the chassis 10. Specifically, the fixed end of the electric push rod 12 is mounted on the rear axle of the suspension assembly, and the movable end of the electric push rod 12 is mounted on the chassis. The chassis 10 is raised and lowered by extending and retracting the electric push rod 12.

[0041] Please refer to this as well. Figures 1 to 6 A lifting mechanism is also provided between the chassis 10 and the suspension assembly. The lifting mechanism includes two sets of X-shaped balance fork arms 16, which are located on both sides of the chassis 10. When the electric push rod 12 extends or retracts, it drives the chassis 10 to rise or fall through the X-shaped balance fork arms 16. The X-shaped balance fork arms 16 include two cross-arranged hinged arms.

[0042] The chassis 10 may be equipped with a support 102, through which the electric push rod 12 and the X-shaped balance fork arm 16 are mounted. When the remote control device issues a command to raise or lower the chassis 10 via the controller 11, the controller 11 controls the electric push rod 12 to extend or retract. As the electric push rod 12 extends or retracts, the X-shaped balance fork arm 16 moves accordingly, causing the chassis 10 to rise or fall horizontally.

[0043] Please refer to this as well. Figures 1 to 6The remote-controlled lawnmower provided by this utility model also includes a tail box 21. The tail box 21 is located near the drive rear wheel 14 and fixed to the chassis 10. At least a power supply 22 and a controller 11 are installed inside the tail box 21. The power supply 22 and the controller 11 are connected by a signal. A tail cover 23 is connected to the outside of the tail box 21. Cooling fans 24 are also installed inside the tail box 21. The cooling fans 24 are distributed on both sides of the tail box 21. The left cooling fan 24 draws air into the box and blows it towards the controller 11 and the power supply 22. The right cooling fan 24 sucks away the air that has been blown over the controller 11 and the power supply 22 and exhausts it outside the box. By setting up the cooling fans 24, the heat generated by the power supply 22 and the controller 11 can be quickly conducted into the air, helping the power supply 22 and the controller 11 to maintain a normal operating temperature and preventing system crashes or performance degradation due to overheating.

[0044] Among them, the power supply 22 is a storage battery. When the engine 18 is not working, all the power supply of the remote control lawnmower is provided by the storage battery. When the storage battery is low, it can be charged by plugging in a 110V-240V wide voltage charger. When mowing, the engine 18 is working. At this time, the high-power magneto of the generator provides AC power, which is then rectified by the controller 11 to obtain a stable 54V DC power output to the storage battery. The output power at this time is greater than the maximum power that the remote control lawnmower can consume, and there is surplus output power to charge the storage battery.

[0045] Please refer to this as well. Figures 1 to 6 The remote-controlled lawnmower provided by this utility model also includes a control panel, which is located above the tail box 21. The control panel can display at least the fuel level information, chassis 10 height information, and power and voltage information of the power supply 22.

[0046] The chassis 10 is equipped with a fuel tank 20, and a fuel level sensor is installed inside the fuel tank 20. The fuel level sensor is connected to the controller 11. With this configuration, the fuel level sensor inside the fuel tank 20 can monitor the fuel level information by changing the resistance of the fuel level sensor according to the change in fuel position.

[0047] The oil level display on the control panel reads changes in the resistance of the oil level sensor and updates the oil level display. The potentiometer inside the electric actuator 12 changes resistance as the actuator extends, and the height display on the chassis 10 on the control panel reads these changes to update the chassis 10's height information. A voltmeter can be connected in parallel across the battery terminals to display real-time charge and voltage information.

[0048] Please refer to this as well. Figures 1 to 6A radar 17 is installed in the center of the front axle of the suspension assembly, and the radar 17 is connected to the controller 11 via a signal. Specifically, the radar 17 can be located in the center of the bumper of the front axle of the suspension assembly. By setting the radar 17, the remote-controlled lawnmower has an active braking function. When the remote-controlled lawnmower is driving, when the radar 17 detects an obstacle, it sends a serial port signal to the controller 11, and the controller 11 cuts off the forward current, thereby performing active braking.

[0049] In addition, the remote-controlled lawnmower is equipped with a buzzer and an alarm light. When the remote-controlled lawnmower brakes actively, the controller 11 controls the buzzer to sound continuously and the alarm light to stay on, in order to remind the user.

[0050] Please refer to this as well. Figures 1 to 6 The tail box 21 is equipped with a grass collection bag 25, which has a hook. The grass collection bag 25 is fixed to the tail box 21 by the hook. During operation, the hook is hung in the hanging hole of the tail box 21, the tail box 21 cover is fastened to the grass collection bag 25, and the torsion spring on the tail box 21 cover is in a compressed state, so that the tail box 21 cover and the grass collection bag 25 are in contact without gaps, the tail box 21 cover does not shake, and the grass collection bag 25 does not fall off.

[0051] The remote-controlled lawnmower provided by this utility model allows the controller 11 to perform operations such as chassis 10 lifting and lowering, cruise control, steering, U-turn, and remote engine start / stop based on signals received by the wireless signal receiver. It offers a high degree of remote control, practical functions, and flexible and convenient use, improving the user experience. The control panel displays information such as the fuel level in the fuel tank 20, chassis 10 height, and power and voltage information of the power supply 22, making it easy for the user to monitor.

[0052] Furthermore, the remote-controlled lawnmower is a plug-in hybrid electric vehicle that can be driven by electricity or fuel. When the battery is low, it can be charged by plugging in a 110V-240V wide-voltage charger. When mowing, the engine 18 works, and the high-power magneto of the generator provides AC power. After rectification by the controller 11, a stable 54V DC power output is obtained and sent to the battery to charge it.

[0053] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0054] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
