Problems solved by technology

However, the internal movement space of the traditional pin puller is relatively closed. In the ground test, the gas in this space is difficult to discharge in a short time, which will generate additional resistance to the movement of the pin shaft, delay the action of the pin shaft, and have a certain impact on the ground test results. Adverse effects, making the state of the ground test inconsistent with the state of use in high altitude or space

Abstract

The invention provides a low-resistance electromagnetic pin puller and a spacecraft, and relates to the technical field of aerospace technologies. The low-resistance electromagnetic pin puller comprises a pin puller housing, an armature moving part, a coil assembly and a resetting mechanism, wherein the armature moving part is inserted into the pin puller housing and can move relative to the pin puller housing; the coil assembly and the reset mechanism are both arranged in the pin puller housing, and the coil assembly is arranged outside the armature moving part and the reset mechanism in a sleeving manner; and a reset gap is reserved between the reset mechanism and the armature moving part, and the reset mechanism is provided with a vent hole group for discharging air in the reset gap. The low-resistance electromagnetic pin puller can reduce the additional resistance caused by the fact that the air cannot be discharged, it is ensured that the armature moving part can move quickly, andthe use state in space is consistent with the ground test state.

Description

Technical field [0001] The invention relates to the field of aerospace technology, in particular to a low-resistance electromagnetic pin puller and a spacecraft. Background technique [0002] The electromagnetic pin puller refers to the use of the principle of electromagnetic conversion to generate electromagnetic force to attract the pin by energizing the coil assembly, and the pin moves against the resistance of the spring, thereby realizing the restriction or release of the restriction of the pin on other structures. [0003] Pin pullers are widely used in the field of aerospace and are mainly used to constrain or release key components of aircraft. Their performance directly affects the success or failure of aerospace vehicles. However, the internal movement space of the traditional pin puller is relatively closed. In the ground test, the gas in this space is difficult to be discharged in a short time, which creates additional resistance to the movement of the pin, delays the m...
