High-adaptability direct charging power supply for lithium battery tool

Abstract

The invention discloses a high-adaptability direct charging power supply for a lithium battery tool. Thehigh-adaptability direct charging power supply comprises a lithium battery tool body; the bottom of the lithium battery tool body is fixedly connected with one end of an elastic connecting assembly, the other end of the elastic connecting assembly is fixedly connected with an outer protection assembly, a driving assembly is connected to the side end face of the outer protection assembly in a clamped mode, the driving assembly is located in the outer protection assembly, an ejection assembly is arranged at the bottom of the inner side of the outer protection assembly, and an electric connection assembly is bonded to the end face of the inner side of the ejection assembly. According to the high-adaptability direct charging power supply for the lithium battery tool provided by the technical schemes of the invention, through mutual cooperation of structures such as an energy recovery assembly, the elastic connecting assembly, the driving assembly, the ejection assembly and the electric connecting assembly, absorption of heat on the surface of an outer protective shell by cooling liquid is effectively improved through circular flowing of the cooling liquid, and the heat energy volatilization amount of a lithium battery pack in unit time is guaranteed, and the stability of the low-temperature air acting on the lithium battery pack is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of lithium electric equipment, more specifically, it relates to a highly adaptable direct charging source for lithium electric tools. Background technique [0002] Lithium electric tools are composed of a motor, a casing and a battery pack. The normal operation of the motor requires a fixed voltage of direct current. Lithium electric tools are continuously charged and discharged during use, and the life of the battery will be greatly reduced. The battery pack needs to be repaired or replaced. At present, the current Some direct charging sources for lithium electric tools still have some deficiencies during use, because the direct charging source will release more heat energy during use, which seriously affects the stability of the direct charging source during use , and the direct charging source is prone to rust during use. Therefore, at this stage, there is an urgent need for a direct charging source for l...

[0002] Lithium electric tools are composed of a motor, a casing and a battery pack. The normal operation of the motor requires a fixed voltage of direct current. Lithium electric tools are continuously charged and discharged during use, and the life of the battery will be greatly reduced. The battery pack needs to be repaired or replaced. At present, the current Some direct charging sources for lithium electric tools still have some deficiencies during use, because the direct charging source will release more heat energy during use, which seriously affects the stability of the direct charging source during use , and the direct charging source is prone to rust during use. Therefore, at this stage, a direct charging source with high adaptability for lithium electric tools is urgently needed to solve the above problems
