Technical Field

[0001] The utility model relates to the technical field of lawn mowers, and in particular to a detachable miniature lightweight hybrid lawn mower. Background Art

[0002] A lawn mower is a mechanical device used to mow grass in lawns, gardens, parks and other places. At present, the common lawn mowers on the market mainly include manual lawn mowers, electric lawn mowers and internal combustion engine lawn mowers. These lawn mowers have their own advantages and disadvantages. For example, manual lawn mowers are easy to operate, but inefficient and suitable for small lawns; electric lawn mowers are efficient, but need to be connected to a power source, are not easy to move, and have safety hazards; internal combustion engine lawn mowers are flexible to move, but noisy, pollute the environment, and have high maintenance costs.

[0003] In order to solve the above problems, some lawn mowers adopt hybrid power systems, that is, using electric motors and internal combustion engines as power sources at the same time to improve the performance and efficiency of lawn mowers. However, existing hybrid power lawn mowers still have some shortcomings, such as complex structure, heavy weight, difficult to disassemble and carry, and the control system is not intelligent enough and cannot automatically adjust according to different lawn conditions and user needs.

[0004] Therefore, it is necessary to develop a detachable miniature lightweight hybrid lawn mower with the advantages of simple structure, light weight, easy disassembly and carrying, and intelligent control system that can automatically adjust according to different lawn conditions and user needs.
