Abstract

The invention provides a lithium-ion storage battery for an outboard power tool used in aerospace, including a lithium-ion storage battery cell, a pressure plate, an outer cylinder, a support rod, an insulating ring, a top cover, a bottom plate, and an electrical connector. The structure of this example is characterized in that : The circular outer cylinder is good for astronauts to grasp with one hand; the floating in-line electrical connector and the guide groove of the battery shell are convenient for astronauts to blindly insert and dock; the metal sealing structure can shield space radiation; the in-line shape can realize the astronaut cabin It can be quickly replaced outside to provide sufficient battery life for electric tools and to deal with emergencies outside the cabin. The structure provided by the invention is simple in layout, less in parts, low in cost, small in size, easy to carry, high in output voltage, and easy to replace. It can also be used as a supporting battery product for electric tools and can be used in civilian products, especially in the field of space.

Description

technical field [0001] The invention relates to a lithium-ion storage battery for an outboard electric tool used in aerospace. Background technique [0002] Lithium-ion battery products are widely used in civil and military fields, especially in the aerospace industry. Battery products can not only be used in large-scale aerospace equipment such as satellites, rockets, and detectors, but also in astronauts' hand tools, robotic arms, In precision mechanical devices such as space suits. [0003] Traditional aerospace lithium-ion batteries cannot be used for astronauts to carry them out of the cabin due to the limitations of large size, radiation resistance of materials, and low output voltage. Contents of the invention [0004] The purpose of the present invention is to provide a lithium-ion storage battery for an out-of-cabin electric tool for aerospace, which can solve the problem that the traditional lithium-ion storage battery for aerospace cannot be used for astronauts...
