Embodiment Construction

[0021] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0022] The present invention is an active heating device for spacesuit gloves outside the cabin, such as figure 1 As shown, it includes box body 1, controller 2, power supply 3, heating sheet 4, negative temperature thermal sensor 5, cable sheet 6, magnet 7

[0023] like figure 1 , the box body 1 is installed between the TMG layer and the restrictive layer at the back of the hand of the extravehicular spacesuit glove 8; since the human body is colder the closer to the fingertips, the temperature is lower, so in the five parts of the extravehicular spacesuit glove 8 The first knuckles of each finger are respectively fixed to the heating sheet 4, and the heating sheet 4 is located between the TMG layer and the limiting layer of the glove 8. Because the temperature at the fingertip is the lowest when the human hand is cold, and the temperature at the f...

Abstract

The invention discloses an active heating device for extravehicular space suit gloves, comprising a box body, a controller, a power supply, a heating sheet, a negative temperature heat-sensitive sensor, a winding displacement sheet and a magnet; the controller comprises an automatic control module and a manual control module, thus realizing automatic heating and manual heating on the extravehicular space suit gloves. Ambient temperature is detected by the negative temperature heat-sensitive sensor to send a temperature signal to the controller, and the controller drives the heating sheet to work so as to finish the automatic heating of the extravehicular space suit gloves. The manual control module is communicated by the magnet, thereby ensuring the heating sheet to heat so as to finish manual heating of the extravehicular space suit gloves. The heating device can ensure the continuity of extravehicular work, improve extravehicular work efficiency and reduce the risk of extravehicular work for astronauts; and in addition, the heating device has small volume, compact structure and convenient operation.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to an active heating device that can automatically or manually heat an astronaut's hand according to the feeling of coldness and warmth of the astronaut's hand. Background technique [0002] When astronauts go out of the cabin, they will encounter the space low temperature environment of -140~-160°C (near-Earth space). Therefore, the extravehicular spacesuit gloves must have the corresponding heat insulation and warmth performance to keep the astronauts' hands comfortable. normal function. Extravehicular space gloves are generally composed of an airtight layer, a confinement layer and a TMG layer (reference: "Spacesuit glove manufacturing enhancements through the use of advanced technologies", author: Cadogan D, Bradley D, from "SAE"). It is generally believed that 0.635cm is the maximum glove thickness that basically maintains the work efficiency of the hand. However, gloves of this thic...
