Efficient power supply battery pack of electric power tool

Abstract

The invention relates to an efficient power supply battery pack of an electric power tool. The battery pack comprises a battery pack shell, a battery assembly is arranged in the battery pack shell, and the battery pack shell comprises a base and a battery pack cover connected with the base. The battery assembly comprises two positioning frames which are oppositely arranged, a plurality of batterycore bodies are arranged between the two positioning frames, and current connecting plate assemblies connected with the two ends of the battery cell bodies are arranged on the two positioning frames.A battery pack protection plate is arranged at the top of the battery assembly, a wiring board assembly is arranged on the battery pack protection plate, and the battery pack protection plate is connected with the current connecting plate assemblies. An electric power tool connecting port corresponding to the wiring board assembly is formed on the battery pack cover, and a plurality of heat dissipation holes are formed in the positioning frames, so that the heat generated by the battery core body is conveniently dissipated.

Description

technical field [0001] The invention relates to the field of battery power, in particular to a high-efficiency power supply battery pack for electric tools. Background technique [0002] An electric tool is a mechanized tool, which is powered by an electric motor or an electromagnet, and drives the working head through a transmission mechanism to perform operations. It is usually made into a hand-held and movable type. The electric tool has a light structure and is easy to carry and use. Compared with hand tools, the production efficiency can be increased several times to dozens of times. Power tools have been widely used in various fields of the national economy and have entered home use. Hand-held power tools generally require battery packs to supply power. The overall battery pack The structure directly affects the use efficiency of electric tools. Currently, there are generally multiple battery cores in the battery pack of electric tools, and the current output of multi...

Compared with hand tools, the production efficiency can be increased several times to dozens of times. Power tools have been widely used in various fields of the national economy and have entered home use. Hand-held power tools generally require battery packs to supply power. The overall battery pack The structure directly affects the use efficiency of electric tools. Currently, there are generally multiple battery cores in the battery pack of electric tools, and the current output of multiple battery cores has the problem of non-concentrated current output;

[0003] In addition, the current power tool battery packs are not designed well enough for the protection of the battery core and heat dissipation, and there are problems of poor heat dissipation and damage to the battery core
