Specifically, referring to fig. 11, the specific operation process of the lawn mower is as follows:
when the working state of the mower changes (such as the movable upper cover of the mower moves upwards or the mower is suspended and lifted), the lifting limiting part moves upwards along with the suspension ball head to drive the magnetic block to be far away from the reed switch on the lifting detection plate, so that the reed switch is opened or closed, the current signal generated by the lifting detection plate changes, the current signal changes and is transmitted to the control assembly of the mower, and the main control controls the mower to stop working and give an alarm. Preferably, in a normal working state of the mower, the magnetic block is close to the reed switch, so that the reed switch is in a closed state; when the working state of the mower changes, the magnetic block is far away from the reed switch, the reed switch is opened, and the detection board is lifted to generate current signal changes. Therefore, the invention uses the magnet type suspension lifting detection component to monitor the working state of the mower, and utilizes the relative position change between the magnetic block and the reed switch to enable the lifting detection plate to generate current signal change (namely detection signal) so as to enable the control component to control the mower to stop working and give an alarm according to the current signal change, and the invention has the advantages of simple principle, difficult generation of a large amount of electromagnetic radiation, higher safety, reduced device cost and the like.
In summary, the suspension lifting detection assembly and the mower provided by the invention have the advantages that the magnetic block is lifted by utilizing the displacement state of the movable upper cover, so that the relative position between the magnetic block and the reed switch is changed, the lifting detection plate is caused to generate current signal change (namely detection signal), then the control assembly controls the mower to stop working and give an alarm according to the current signal change, the principle is simple, a large amount of electromagnetic radiation is not easy to generate, the safety is higher, the cost of devices is reduced, and the like.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
