Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to a new type of intelligent lawnmower. Background Technology

[0002] As a tool suitable for quick and efficient lawn mowing, lawnmowers are widely used in urban greening and home weeding. Lawnmowers have further expanded to include new intelligent lawnmowers. These new intelligent lawnmowers can autonomously complete the lawn mowing work without direct human control or operation, and are characterized by low power consumption, low noise, and a compact and aesthetically pleasing design, significantly reducing manual operation.

[0003] As prior art, Chinese patent CN221104087U proposes a smart lawnmower, including... The system includes: a smart lawnmower body; casters, with casters fixedly installed at the four corners of the bottom of the smart lawnmower body; a mounting groove, with a mounting groove at the center of the bottom of the smart lawnmower body; a mowing assembly, with a mowing assembly inside the mounting groove for cutting grass, the mowing assembly including a hydraulic cylinder, a mounting plate, a motor, a shaft, a mowing blade, a connecting plate, and a positioning port, the top of the inner wall of the mounting groove being movably connected to the hydraulic cylinder; and a limiting assembly, with a limiting assembly inside the mounting groove.

[0004] While the above solution enables the lawnmower components to be detachable, in actual use, disassembly still requires operating the electric push rod and manually pulling the components, which involves many steps and limits its convenience. Moreover, the hydraulic cylinder structure is complex and costly, and there is a possibility of oil leakage or sealing problems after long-term use. Therefore, there is still room for improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a new type of intelligent lawnmower to solve the problems mentioned in the background section.

[0006] To solve the above technical problems, this utility model adopts the following technical solution: A novel intelligent lawnmower includes a lawnmower body and a lawnmower assembly. The lawnmower body has four casters at its bottom corners and a mounting groove in the center. The lawnmower assembly is detachably connected to the mounting groove. The lawnmower assembly includes a mounting frame, a motor, and a cutting blade. A pair of slots are provided on the upper left and right side walls of the mounting groove. A pair of inserts and a drive assembly for driving the inserts to move horizontally are provided on the upper part of the mounting frame. After the inserts move horizontally, they can be inserted into or separated from the slots. A pair of side plates are vertically provided on the lower front and rear of the mounting frame. A pair of horizontal plates are provided at the bottom of the side plates. A screw and a guide rod are respectively provided between the side plates and the horizontal plates. The utility model also includes a lifting plate that is threaded to the screw and slidably connected to the guide rod on both sides, and a power device for driving the screw to rotate. The lifting plate is slidably connected to the guide rod through a sliding hole. The motor and the cutting blade are installed below the lifting plate.

[0007] Using the above technical solution, when installing or disassembling the lawnmower components, the mounting frame is placed into the mounting slot. The drive assembly controls a pair of insert blocks to move horizontally and then insert into the slot for fixation, thus achieving the fixing and disassembly of the mounting frame. Disassembly and installation are automated with a single click, simplifying the disassembly process. No manual tools are required for assembly or disassembly. Activating the power unit rotates the screw, causing the lifting plate to slide up and down along the guide rod, adjusting the height of the mower blades. The use of an electric screw for height adjustment is lighter, simpler to maintain, and reduces costs.

[0008] As a further optimization of this utility model, the power device is a second motor located above the mounting frame, and the output end of the second motor is connected to the first screw.

[0009] As a further optimization of this utility model, a pair of connecting plates are provided at the left and right ends of the mounting bracket. The driving assembly includes a motor, a guide rod and a pair of screws located between the pair of connecting plates. The motor is a dual-axis motor and its output end is connected to the pair of screws. It also includes a pair of movable plates that are respectively connected to the pair of screws. The movable plates are slidably connected to the guide rods. The movable plates are slidably connected to the guide rods through sliding holes. The pair of inserts are respectively located on the pair of movable plates.

[0010] Using the above technical solution, when motor three is turned on, the motor rotates and drives a pair of screws two to rotate simultaneously, thereby causing a pair of movable plates to move closer or further apart, so that a pair of insert blocks move closer or further apart, thus achieving simultaneous insertion or separation from the slot.

[0011] As a further optimization of this utility model, the top four corners of the mounting groove are provided with positioning grooves, and the top of the mounting bracket is provided with positioning blocks that can be inserted and cooperate with the positioning grooves. The length of the positioning block is greater than the sum of the depth of the positioning groove and the height of the insertion block.

[0012] Using the above technical solution, the mounting bracket is positioned with the mounting slot by the cooperation of the positioning block and the positioning slot, so that the position of the plug and the slot can be aligned.

[0013] As a further optimization of this utility model, the width of the lawn mower blade is less than the horizontal distance between a pair of horizontal plates.

[0014] Using the above technical solution, when the lifting platform rises, the lawn mower can be stored between a pair of side panels, making reasonable use of space.

[0015] The beneficial effects of this utility model are as follows: When installing or disassembling the lawnmower components, the mounting frame is placed in the mounting slot, and a pair of insert blocks are controlled by the drive component to move horizontally and then insert into the slot for fixation, thereby realizing the fixation and disassembly of the mounting frame. Disassembly and installation are achieved automatically with one click, simplifying the disassembly steps. Disassembly and assembly can be completed without manual operation tools; when the power unit is turned on, the screw rotates, thereby causing the lifting plate to slide up and down along the guide rod, realizing the adjustment of the lawnmower height. The use of an electric screw structure for height adjustment is lighter and easier to maintain, reducing costs. Attached Figure Description
