[0002] Agricultural and horticultural operations encompass multiple stages, including sowing, tilling, plant protection, pruning, harvesting, weeding, and snow removal. To address these diverse operational needs, the market has developed highly specialized machinery, such as lawnmowers for lawn mowing, snowplows for winter snow removal, tillers for land preparation, and seeders for crop planting. These machines have undergone long-term development, resulting in mature mechanical structures, power systems, and operating methods, forming the foundation for modern agricultural and forestry production and horticultural maintenance. Currently, most equipment still uses specialized units to perform specific tasks, lacking universal power modules. Specific operational needs require the purchase of dedicated equipment, making interoperability difficult and increasing operating costs. While existing specialized equipment performs well in single operational scenarios, its inherent design concepts and operating modes are no longer suitable for the new trends in modern agricultural and horticultural management towards intelligence, efficiency, and low cost. Furthermore, current equipment has relatively poor environmental perception and recognition capabilities, resulting in reliance on manual operation. Operators need to drive or follow the equipment to complete tasks, which is cumbersome and inefficient. Utility Model Content

[0016] Example: See Figures 1-9 A modular powertrain includes a vehicle body 1, a running gear 3 mounted on the lower side of the vehicle body 1 near the front end, and a rear support frame 4 mounted near the rear end. The front end of the vehicle body 1 is provided with a quick-connect mechanism for quick connection with different load working heads.

[0017] Specifically, the vehicle body 1 includes a chassis 8 and a body shell mounted on the chassis 8, the chassis 8 being composed of several main beams. In this design, the quick-assembly mechanism includes a first connecting portion located at the front end of the vehicle body 1, wherein the first connecting portion includes a positioning beam 26 extending forward from the middle of the front end of the vehicle body 1, and first connecting beams 27 located on both sides of the positioning beam 26. Specifically, the first connecting beam 27 is made of channel steel with its opening facing downwards, and at least two first connecting holes distributed along its length are formed on the web of the first connecting beam 27. Correspondingly, only a connecting plate corresponding to the positioning beam and a second connecting beam corresponding to the first connecting beam are needed on the working assembly to achieve quick connection. During processing, positioning holes through which the positioning beam 26 can pass are formed on the positioning plate to achieve quick positioning. Then, the second connecting beam corresponds to the first connecting beam 27 and can be sleeved, overlapped, or butted with the first connecting beam 27.

[0018] In this solution, the walking assembly includes two drive motors and two walking wheels. The drive motors are fixedly connected to the chassis, and their motor shafts are directly or via a reduction mechanism connected to the walking wheels through the wheel axles. In this way, the two walking wheels can be controlled independently, making walking, steering, and other controls more convenient and accurate.

[0019] A power supply module is located on the upper side of the chassis 8. This module includes multiple batteries to power the drive assembly, and the garage cover is positioned above the batteries. Multiple uprights, arranged in a rectangular pattern, are mounted on the chassis 8, with the power supply module located inside these uprights. Each upright 9 includes crossbeams and columns, forming installation spaces between adjacent columns. Mounting plates can be installed between adjacent columns as needed. These independent installation spaces facilitate the installation of different types of electrical components or motor controllers, providing ample space and improving the overall compactness of the machine. Simultaneously, they offer some isolation, preventing interference between electrical components and controllers, and facilitating wiring and maintenance.

[0020] As an alternative implementation, with subsequent structural compact design, the support frame 9 can be eliminated, and each electrical component or controller can be installed on the underside of the chassis 8, installed independently in sections, in order to reduce the overall volume of the vehicle body 1.

[0021] The vehicle body is equipped with an openable cover 40 for easy replacement of the battery 10 or maintenance, and an emergency operation panel 43 is installed on the vehicle body. The emergency operation panel 43 is also equipped with multiple operation buttons, including an emergency stop button and a key start / stop knob.

[0022] A rain sensor 42 is also installed on the vehicle body. Specifically, a battery box 10 is provided within the rectangular area enclosed by the support frame 9. The battery box 10 is divided into multiple battery mounting slots by partitions, and multiple batteries 10 are correspondingly snapped into the mounting slots to prevent the batteries 10 from shaking and to provide stability. At the same time, there is a gap between the battery box 10 and the vehicle body, and the support frame 9 is located in this gap, thereby providing installation space for electrical components or controllers mounted on the support frame.

[0023] An environmental sensing module 5 and a communication module 6 are also installed on the vehicle body; the power supply module supplies power to both the environmental sensing module and the communication module.

[0024] In this embodiment, the environmental perception module 5 includes a first visual sensor 501 (a binocular camera in this embodiment) and / or a millimeter-wave radar 502 and / or a lidar 503 mounted on the front side of the top of the vehicle body, and / or second visual sensors 504 (monocular cameras in this embodiment) on the sides and rear of the vehicle body, and / or multiple anti-collision radars 11 (ultrasonic radars in this embodiment) distributed along the width direction of the rear end of the vehicle body 1. Specifically, the first visual sensor 501 is located at the front center of the vehicle body 1, with its detection end facing the front of the vehicle body 1. This limitation does not apply if a 360° surround-view camera is used. The second visual sensor 504 is used to supplement the visual signal acquisition of the blind spots on both sides of the first visual sensor 501.

[0025] In this embodiment, the communication module 6 includes an RTK antenna 601 and / or a 915M antenna 602 mounted on the vehicle body 1. The RTK antenna 601 works with the base station to locate the robot, while the 915M antenna 602 is used to communicate with remote control, Bluetooth devices, or other communication devices. The specific antenna type or the specific settings of the communication module 6 can be selected according to actual needs, such as GPS satellite communication, positioning, remote short-range communication, local area networking, etc.

[0026] In implementation, this solution also includes a controller, which transmits information collected by the sensing module to the remote control terminal via the communication module, and simultaneously receives instructions from the remote control terminal via the communication module to control the device's movement and operation; the data transmission and movement control are mature existing technologies and will not be described in detail here. The controller is also powered by a power supply module.

[0027] Since the powertrain is an independent and universal unit, and important electrical components such as the battery 10 are installed on it, it needs to be able to operate independently and stably when not carrying a load. Therefore, in this embodiment, the rear support frame 4 includes two support plates 31 that are positioned opposite each other on the lower rear side of the vehicle body 1. A support leg 32 is rotatably mounted between the two support plates 31 via a pivot. The support leg 32 is a rectangular frame structure formed by an upper frame, a lower frame, and two side frames. Its side frames are connected to the support plates 31 by springs 33. The lower frame of the outrigger 32 extends to both sides of the plane containing the outrigger 32 to form an enlarged structure 34, increasing the area of ​​the support surface 36 and the support effect. The upper frame of the outrigger 32 bends and extends to the rear side of the plane containing the outrigger 32 to form a support part 35. A support surface 36 is formed on the support part 35. When the outrigger 32 rotates to the rear side of the vehicle body 1 to the support position, the support surface 36 abuts against the lower side of the vehicle body 1, allowing the weight of the vehicle body 1 to be better transferred to the rear support frame 4 through the support surface 36, thereby increasing the area of ​​the support surface 36 and the support effect. A fixing arm 37 is also provided on the lower side of the vehicle body 1. The end of the fixing arm 37 is provided with a snap-fit ​​plate 38 formed by two opposing elastic plates. Correspondingly, a snap-fit ​​connector 39 is provided on the side frame of the outrigger 32. When the outrigger 32 rotates to the front side of the first vehicle body 1 to the retracted position, the snap-fit ​​connector 39 snaps into the snap-fit ​​plate 38. In use, the rear support frame 4 rotates forward and is fixed by the snap-fit ​​structure of the fixed arm 37. It is used to fix the rear support frame 4 when it is retracted during operation. The spring 33 also plays an auxiliary role to prevent the rear support frame 4 from falling. When the rear support frame 4 rotates backward to the support position, the support surface 36 on the support part 35 of the rear support frame 4 abuts against the main beam at the rear end of the chassis 8 to improve the support effect. In addition, multiple decorative grooves are provided on the support part 35 along the width direction of its body 1 to improve the aesthetics.

[0028] The outrigger 32 also includes a locking mechanism. Specifically, the locking mechanism includes a plane bearing 45 sleeved on the pivot of the outrigger 32. Between the plane bearing 45 and the support plate 31, there is a fixed block 47 fixedly connected to the support plate 31 and a rotating block 48 that can rotate around the pivot and slide along the pivot. A clamping nut is installed on the other side of the plane bearing 45. The rotating block 48 is fixedly connected to a handle 46. A first slot 49 and a second slot 50 are provided on the side opposite to the fixed block 47 and the rotating block 48. The first slot 49 and the second slot 50 are connected by an inclined plane 51. Correspondingly, a locking block is provided on the rotating block 48. When the rotating block 48 rotates, the locking block can move from the first slot 49 to the second slot 50 via the inclined plane 51. During this process, the rotating block 48 slides along the pivot away from the fixed block 47, thereby squeezing the plane bearing 45 and locking the plane bearing 45, thereby locking the outrigger 32.

[0029] When the powertrain (and running gear) is separated from the work assembly, the powertrain, having only two wheels, cannot be stably supported. At this point, the rear support structure, with its outriggers extended and in a supported position, provides stable and effective support for the powertrain, ensuring its stability when placed independently.

[0030] In summary, this utility model, through modular design and the use of a universal powertrain as the main drive mechanism, can be adapted to various garden operation heads. It allows for easy replacement of the equipped work heads according to work needs, and the quick-installation mechanism enables rapid switching between different work heads to meet diverse work requirements. The structure is simple, highly versatile, and quick to assemble and disassemble. Furthermore, it integrates environmental sensing and remote communication, enabling better perception and identification of the environment, thus facilitating applications in remote control and intelligent operation. This allows it to adapt well to the future development of unmanned and intelligent agricultural and garden equipment, improving operational efficiency.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
