Electric tool gear adjustment circuit and method thereof

Abstract

The invention discloses a gear adjustment circuit of an electric tool and a method thereof. The positive terminal of the circuit is electrically connected to a motor through an inverter, the inverter is electrically connected to a controller, the controller is electrically connected to a gear switching module, and the inverter The device is electrically connected with a current acquisition module, and the operation module is electrically connected to the current acquisition module to detect the current when the electric tool is loaded; the timing unit is electrically connected to the operation module to count the current duration of the electric tool when it is loaded in each gear; the operation module Call and compare the current duration accumulated by the calculation module in different stages, and adjust the gear for restarting the electric tool. The present invention changes the gear switching mode of the conventional electric tool, adopts a more humanized gear switching mode, makes the gear adjustment of the electric tool more intelligent, can automatically adapt to the user's usage habits, meets the user's habitual needs, and reduces redundant gears Switch actions to increase user productivity.

Description

【Technical field】 [0001] The invention relates to the field of electric tools, in particular to an electric tool gear adjustment circuit and a method thereof. 【Background technique】 [0002] Electric tools mainly include electric drills, electric hammers, impact drills, curve saws, angle grinders, electric circular saws, cutting machines, electric planers, grinders, impact wrenches, etc., which are mostly used in automobile assembly, railways, medical treatment, construction machinery, Metallurgy, mining, decoration, furniture auto repair, construction and other fields. [0003] As we all know, many electric tools have multiple adjustable gears, and users can adjust the adapted gears according to their own needs to operate. When using electric tools, whether the gears can quickly match the user's habitual operation, Greatly affect the user's work efficiency. [0004] At present, when the existing electric tools are used again, the gears that are turned on again are basical...
