The electric lawn mower is a mechanical tool used for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutter head is installed on the walking wheel, the cutter head is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, saving the working time of the weeding workers and reducing a lot of human resources. In countries where the mechanization of animal husbandry is highly developed, the research on electric lawn mowers is developing in the direction of high speed and energy saving.
The development of electric lawn mowers promotes agricultural mechanization, improves work efficiency, and improves agricultural production efficiency. It is particularly important in a large agricultural country like ours. As an important tool in agricultural production, lawn mowers have the most direct impact on crop yields. Its invention is a major advancement in human civilization. A lawn mower is a mechanical tool used to mow lawns and vegetation. There are diesel engines and gasoline engines. It is composed of cutter head, engine, traveling wheel, traveling mechanism, blade, armrest, control and other parts. The blade uses the high-speed rotation of the engine to greatly increase the output speed, which saves the work time of the weeding workers and reduces a lot of human resources.
In this electric lawn mower, the cut grass is transferred to the rear of the machine body through the reel part and finally collected in a grass bag. Since the cut grass tends to stick to the surface of the reel, it is necessary to clean the reel part from time to time. Therefore, there is a strong need for an improved electric lawn mower so that the operator can clean its reel more easily. Electric lawn mowers can fully meet this requirement. The reel part is set on one of the left and right sides of the machine body, and the power switch/key can be inserted into the concave connection (ie, the power switch) is set on the left or right side of the machine body. One side. Therefore, the user can pull the power switch/key out of the concave connection in the body on the same side of the body and place the body sideways. That is, the user is allowed to complete two required operations: inserting and unplugging the power switch/key, and placing the body sideways without changing his or her operating position. In this way, the efficiency and convenience of cleaning the reel are greatly improved. Moreover, by providing a connection with a concave machine side integrally engaged with the motor-controlled control part, it allows efficient assembly of the electric lawn mower.
The electric lawn mower is driven by the battery to rotate the electric motor, the control part is used to control the electric motor to allow the body to run and realize various functions, and is mainly used as the relay component of the power switch, which is arranged between the battery and the control part Used for electrical connections in between. Here, the battery and the control part can be electrically connected to each other through a predetermined connection part, such as a power switch/key plug-in relay part, and a predetermined connection part is pulled out from the relay part to disconnect the electrical connection between each other. . With this structure, the battery and the control part can be completely disconnected from each other by withdrawing from the relay part through the predetermined connection part, and it is possible to make the battery in the non-operating or stationary period of the electric working machine. Unnecessary discharge is minimized and over discharge is prevented during long-term storage of the working machine. In this way, the working life of the battery can be extended.
The relay component of the electric lawn mower includes a connection part provided on the side of the body for connecting the charger to charge the battery, so that the same relay component can be selectively connected to predetermined connection components, such as power on/off. The key, or charger. That is, when the electric working machine is working to complete its main function, such as the mowing function, the predetermined connection components, such as the power on/off key, can be inserted or connected to the relay component, and the charger can be inserted into the relay component when the battery is charged. Or connect with relay components. In this way, the working efficiency and convenience of the electric working machine during battery discharge (that is, during the mowing process) or charging period are greatly improved, and at the same time, accidental insertion of predetermined connecting parts or chargers can be reliably avoided.
The battery used in the electric lawn mower is preferably a nickel-based or lithium-based battery. It is well known that the temperature control of nickel-based or lithium-based batteries during charging is relatively easy. Therefore, the nickel-based or lithium-based battery used in the electric lawn mower can greatly improve the charging efficiency. In addition, the control part has the function of monitoring and controlling the battery temperature, thereby improving the reliability of battery charging. Therefore, the battery can have a longer working life. In the electric working machine, the relay component includes a positive terminal connected to the positive electrode of the battery, and the positive terminal of the relay component is also used as a charging positive terminal for connecting the charger and the positive electrode of the battery. This structure can simplify the structure of the control part and the relay component. Thereby, the necessary overall cost of the electric working machine can be reduced to a reasonable level.
