Description

Intelligent mower

Technical Field

The utility model relates to an intelligence garden instrument, especially an intelligence lawn mower.

Background

The intelligent lawn mower is widely applied to maintenance of household courtyard lawns and trimming of large lawns. The intelligent mower is controlled by a programmable single chip Microcomputer (MPU), is powered by a rechargeable battery pack (generally a lithium battery pack), and automatically walks according to a certain path plan and mows within an electronic fence wall range generated by a boundary wire laid in advance. When the voltage of the battery pack is low or other reservation conditions are met, the charging station is automatically returned to charge, and the next mowing operation is waited.

The intelligent mower belongs to an outdoor mobile robot, the general working mode of the intelligent mower is that the intelligent mower automatically works according to a preset program in 24 hours all day in a lawn, and in a normal state, the intelligent mower is charged or standby on a charging base station or carries out mowing operation within the range of an electronic fence wall without manual intervention.

The mechanical structure of intelligent lawn mower includes: the intelligent mowing machine mainly comprises a frame body, wheels, a driving motor with a speed reducer, a mowing motor, a storage battery, a sensing system, a control system, a power switch, a buzzer and the like, and a reasonable mechanical structure design can provide reliable stability, safety and flexibility for the mowing robot in operation. Particularly in rainy weather, the working environment of the intelligent mower is very severe; the machine must be designed to be waterproof to prevent internal rain-sensitive components from wetting and running down. Therefore, the frame body of the intelligent mower is generally designed into a closed cavity formed by combining an upper shell and a lower shell, and all parts sensitive to rainwater, such as a control circuit board, a motor, a battery, a power switch, a buzzer and the like, are accommodated in the closed cavity.

Rechargeable batteries (typically lithium batteries) used by intelligent mowers power the control and motion systems of the entire machine. The battery pack is generally designed as an independent battery pack, is packaged by a hard plastic shell or a soft heat shrinkable sleeve, is connected with a host through a connecting terminal, provides energy for the host and communicates with the host.

First, the service life of the rechargeable battery pack is limited, and the full charge-discharge cycle life is generally 200-2000 times according to the physicochemical characteristics of the battery cell. When the useful life of the battery pack is complete, the battery pack must be replaced. Second, smart mowers are not needed in winter. Therefore, generally, in winter, if the battery pack can be taken out of the machine and stored separately from the intelligent mower, the self-discharge of the battery pack can be reduced, and the service life of the battery pack can be prolonged. Finally, this rechargeable battery, in particular the lithium battery, is a relatively expensive component; many users purchase different types of machines, such as electric drills, handheld mowers, chain saws, etc., in order to save the purchase cost, but only a small number of 1 or more battery packs are purchased, and when the different types of machines are used, the 1 or more battery packs are used for supplying power. This requires the battery pack to be optimized for construction with the machine so that the battery pack can be easily removed from the machine or easily installed on the machine.

The battery pack of the intelligent mower generally adopts a built-in structure, and the common placing methods include two types:

one is a sealed cavity formed by combining an upper shell and a lower shell. The disadvantage of this construction is that the upper and lower housings of the machine must be completely disassembled and opened when the battery pack needs to be disassembled. This task is complex, and it is also easy to damage the components of the machine or to break the sealing structure thereof, and it is generally not recommended to be completed by non-professional users.

The other type is that a battery compartment is arranged at the bottom of the lower shell, and a battery pack is placed in the battery compartment. In order to maintain the sealing performance of the cavity formed by combining the upper shell and the lower shell, a battery compartment cover is required to be arranged on the battery compartment; the battery compartment cover is connected with the bottom of the lower shell through screws, and meanwhile, a sealing piece is arranged between the battery compartment cover and the bottom of the lower shell to prevent rainwater from entering the sealed cavity. The disadvantage of this configuration is that when it is desired to disassemble and assemble the battery pack, the machine must be turned over and the screws on the battery compartment cover removed with a tool (e.g., a screwdriver) to open the battery compartment cover and remove or install the battery pack. Although the user can do this, the detaching process is still laborious.
